D. Risk Factors
An investment in our business involves risk, and readers should carefully consider the risks described below and in our other filings on the SEDAR+ website and filed with the U.S. Securities and Exchange Commission ("SEC") on EDGAR. Our ability to generate revenue and profit from our technologies is dependent on a number of factors, and the risks identified below, if they were to occur, could have a material impact on our business, financial condition, liquidity, results of operations or prospects. Additional risks and uncertainties not presently known to us or that we currently consider immaterial may also impair our business operations. These risk factors could materially affect our future operating results and could cause actual events to differ materially from those described in our forward-looking statements.
Risks Related to our Business and the Automotive Industry
Our products face, and will continue to face, significant competition from competing alternative powertrain technologies, including from incumbent technologies, improvements to current powertrain technologies, and new alternative powertrain technologies (such as fuel cell and battery electric technologies). As the market for our products continues to grow, this competition may increase. New developments in technology may negatively affect the development or sale of some or all our products or make our products noncompetitive or obsolete. Other companies, many of which have substantially greater customer bases, businesses, and financial and other resources than us, are currently engaged in the development of products and technologies that are similar to, or may be competitive with, certain of our products and technologies.
Competition for our products may come from a wide range of established and emerging powertrain and fuel system technologies. Each of our target markets is currently serviced by existing manufacturers with existing customers and suppliers using proven and widely accepted technologies. Many existing manufacturers have or had natural gas and hydrogen engine programs and could develop new engines without our help or components, using other technologies or technologies from competitive companies. Additionally, there are competitors working on developing technologies such as cleaner diesel engines, biodiesel, fuel cells, advanced batteries and hybrid battery/internal combustion engines, and new fuels in each of our target markets. Each of these competitors has the potential to capture market share in various markets, which could have a material adverse effect on our position in the industry and our financial results. For our products to be successful against competing technologies, especially diesel engines, they must offer advantages in one or more of these areas: regulated or unregulated emissions performance, including CO2 reduction; fuel economy; fuel cost; engine performance; power density; engine and fuel system weight; and engine and fuel system price. There can be no assurance that our products will be able to offer advantages in all or any of these areas.
The market for vehicles with our fuel systems may be limited or may take longer to develop than we anticipate and/or certain products may not achieve widespread adoption.
Vehicles with our alternative fuel systems represent an emerging market, and we do not know the extent to which end-users will ultimately want to use them or to pay for any initial incremental purchase price over and above a competing technology or a technology that may have a preferential advantage due to government incentives. The development of a mass market for our fuel systems may be affected by many factors, some of which are beyond our control, including: the
7

emergence of newer, more competitive technologies and products; the future cost of natural gas and other fuels used by our systems; the future cost of diesel, gasoline and other alternative fuels that may be used by competitive technologies; the ability to successfully build the refueling infrastructure necessary for our systems; changes to regulatory requirements; availability of government incentives; customer perceptions of the safety of our products; and customer reluctance to try a new product. If a market fails to develop or develops more slowly than we anticipate, we may be unable to recover the investments we will have made in the development of our products and may never achieve profitability.
Our technologies have been commercialized in heavy-duty trucks, medium-duty vehicles, and construction, bus, rail, forklift and passenger car applications. However, we do not know whether we will successfully grow these market offerings as required to realize a long-term sustainable business where higher volumes are important drivers to bring costs in line with customer expectations.
Management identifies a material uncertainty regarding our ability to continue as a going concern

Management continues to identify a material uncertainty that raises substantial doubt about the Company's ability to continue as a going concern. Based on the Company's projected capital expenditures, debt servicing obligations and operating requirements under its current business plan, we anticipate that our cash and cash equivalents will not be sufficient to fund our operations through the next twelve months from the date of the issuance of this annual report.
We may need to raise additional funding in order to continue as a going concern and we cannot provide any assurance that it will be successful in doing so. If we are unable to improve its liquidity position when required, we may not be able to continue as a going concern.
Our growth is dependent on available refueling infrastructure, fuel price differentials and environmental regulations, policies and government incentives which may not persist or develop as we anticipate.
Natural gas and hydrogen must be carried on board in liquefied or compressed form and refueling infrastructure is not as well developed as gasoline and diesel fuel infrastructure in many jurisdictions. Although alternative refueling infrastructure is expanding, there can be no assurance of the successful expansion of the availability of such infrastructure to meet projected demand. If customers are unable to obtain fuel conveniently and affordably, a mass market for vehicles with our technology is unlikely to develop.
The acceptance of low carbon fueled engines may depend in large part on the price differential between low carbon fuels and diesel after incentives. Current oil price volatility and natural gas price volatility may change what has, at certain times and in certain markets, been a price advantage for natural gas, including Renewable Natural Gas (RNG), and biogas. This price differential is affected by many factors, including changes in the resource base for natural gas compared with crude oil, availability of shale gas, pipeline transportation capacity for natural gas, refining capacity for crude oil, exports for refined products and government excise and fuel tax policies and geopolitical pressures. There can be no assurance that natural gas, RNG, or biogas will consistently remain less expensive than diesel and gasoline fuels in all geographies. This may impact upon potential customers' decisions to adopt gaseous fuels as a transportation energy solution in the short term.
While we have benefited historically from certain government environmental policies, mandates and regulations around the world, there are indications this may change regarding fossil natural gas, where some jurisdictions are keen to move to incentive for only carbon neutral or carbon free fuels. Examples of such regulations include those that provide economic incentives, subsidies, tax credits and other benefits to purchasers of low emission vehicles, restrict the sale of engines that do not meet emission standards, fine the sellers of non-compliant engines, tax the operators of diesel engines and require the use of more expensive ultra-low sulfur diesel fuel. There can be no assurance that these policies, mandates, and regulations will be continued. Incumbent industry participants with a vested interest in gasoline and diesel, many of which have substantially greater resources than we do, may invest significant time and money to influence environmental regulations in ways that delay or repeal requirements for clean vehicle emissions. If these are discontinued, if current requirements are relaxed, or if other regulations (for example those related to zero carbon) are implemented that may impact our business.
Failure of our products to perform as expected could negatively impact our ability to develop, market and sell our products.
If our products contain defects in design and manufacture that cause them not to perform as expected or that require repair, our ability to develop, market and sell our products could be impaired. While we attempt to address any identified product issues as effectively and rapidly as possible, any lack of timeliness may impede production or not satisfy our customers.
8

While we have performed extensive quality control on our products, we cannot provide assurance that we will be able to detect and fix all defects in our products prior to their sale to or installation for customers.
Any product defects, delays or legal restrictions on product features, or other failure of our products to perform as expected, could harm our reputation and result in delivery delays, product recalls, product liability claims, breach of warranty claims, and significant warranty and other expenses, and could have a material adverse impact on our business, financial condition, operating results and prospects.
We will need to raise additional funds to grow our business and meet our financial obligations. If we cannot raise additional funds when we need or want them, our operations and prospects could be negatively affected.
The design and manufacture of powertrain technologies is a capital-intensive business, and the specific timing of cash inflows and outflows may fluctuate substantially from period to period. Until we are consistently generating positive free cash flows, we may need or want to raise additional funds through the issuance of equity, equity-related or debt securities or through obtaining credit from financial institutions to fund, together with our organic cash flows from operations, the costs of developing and manufacturing our current or future products, to pay any significant unplanned or accelerated expenses or for new significant strategic investments, or to refinance our indebtedness, even if not required contractually. We may need sufficient capital to fund our ongoing operations, and continue research and development "R&D" projects for future generations of our products and/or technologies. We cannot be certain that additional funds will be available to us on favorable terms when required, or at all. If we cannot raise additional funds when we need them, our financial condition, results of operations, business and prospects could be materially and adversely affected.
We are dependent on relationships with our suppliers.
While we have a diverse supply base with various manufacturers, certain suppliers provide components or materials that are critical to our products, and we are dependent on their ability to source materials, manage their capacity, workforce, and schedules as well as their ability to ramp up capacity and maintain quality and cost to support our production requirements. For several reasons, including but not limited to shortages of parts, labor disruptions, lack of capacity and equipment failure, a supplier may fail to supply materials or components that meet our quality, quantity or cost requirements or to supply any at all. If we are not able to resolve these issues or obtain substitute sources for these materials or components in a timely manner on terms acceptable to us or at all, our ability to manufacture certain products may be harmed, and we may be subjected to cancellation of orders or penalties for failed or late deliveries, which could have a material adverse effect on our business and financial results. Our products also use steel and other materials that are in global demand. The prices and quantities at which those supplies are available fluctuate and may increase significantly. Competitive pressure, however, may not allow us to increase the sales price of our products. Any such increases may therefore negatively affect our margins and financial condition. We mitigate these risks by seeking secondary suppliers, carrying inventory and locking in long-term pricing when possible. There are no guarantees, however, that we will be successful in securing alternative suppliers or that our inventory levels will be sufficient for our production requirements.
We conduct business in foreign markets that carry risk.
We conduct a substantial portion of our business in foreign markets that may carry risks relating to: political and economic uncertainty, including those related to nationalization, war, civil unrest, insurrection, acts of terrorism, and other political risk; corruption risks; high inflation; trade, customs and tax risks; currency exchange rates; limitations on the repatriation of funds; competition to attract and retain qualified employees; risks of pandemics or other outbreaks of illness, disease or virus; expropriation of property and equipment; and other risks associated with conducting business internationally, including other actions by governments that may adversely affect our operations. Expansion of our business internationally to where gaseous fuel systems are opening due to favorable climate change-related regulation is an important element of our long-term strategy. Consequently, our exposure to the risks described above may be greater in the future and the potential risks to us will vary from country to country and are unpredictable. The occurrence of any such risks could have an adverse effect on our operations, profitability and financial condition.
We derive a substantial portion of our revenue from production and sales by subsidiaries outside of Canada, and the payment of dividends or the making of other cash payments or advances by these subsidiaries to us may be subject to restrictions or exchange controls on the transfer of funds in or out of the respective countries or result in the imposition of taxes on such payments or advances. We have organized our foreign operations in part based on certain assumptions about various tax laws (including capital gains and withholding taxes), foreign currency exchange and capital repatriation laws and other relevant laws of a variety of foreign jurisdictions. While we believe that such assumptions are reasonable, we
9

cannot provide assurance that foreign taxation or other authorities will reach the same conclusion. Further, we cannot provide assurance that future developments, including changes in government, civil unrest, changes in laws or other disturbances, would not have an adverse impact on our ongoing operations, and thus not have an adverse impact on our operational and financial results.
Our ability to achieve our objectives with respect to our Cespira joint venture may be impacted by its operations and our relationship with the joint venture partner.
We conduct certain of our operations through our Cespira joint venture under contractual arrangements pursuant to which we share ownership and certain management and governance responsibilities with our joint venture partner, Volvo Group. As a result, our ability to realize the anticipated benefits of our investment in Cespira depends in significant part on Cespira's operational performance, its ability to expand commercialization of its products, secure additional customers, achieve anticipated production volumes, and the actions and strategic priorities of our joint venture partner.
From an operational and governance perspective, joint venture arrangements also involve inherent risks. Our joint venture partner's strategic objectives may differ to ours, and disagreements could result in delays or limitations in decision making, including with respect to business strategy, capital allocation, or operational matters. In addition, our ability to implement our operational policies and internal controls within the joint venture may be limited. As a result, we may face increased risks related to adherence to laws and regulations, including but not limited to, tax laws, customs laws, environmental laws, labor laws, permitting laws and regulations, industry laws or international anti-corruption and anti-bribery laws, including Canadian anti-corruption laws and U.S. Foreign Corrupt Practices Act ("FCPA"). The occurrence of any such risks could have an adverse effect on our operations, profitability and reputation.

Our limited production trials, commercial launch activities and field tests could encounter problems.
We conduct limited production trials and field tests on several of our products as part of our product development cycle, and we are working on scaling up our production capabilities. These trials, production readiness activities and field tests may encounter problems and delays for several reasons, including the failure of our technology, the failure of the technology of others, the failure to combine these technologies properly, the failure to maintain and service the test prototypes properly, or changes in macroeconomic or market conditions. Some of these potential problems and delays are beyond our control. Any problem or perceived problem with our limited production trials and field tests could hurt our reputation and the reputation of our products and delay their commercial launch.
We could become subject to product liability claims.
Our business exposes us to potential product liability claims that are inherent to natural gas, hydrogen and products that use these gases. Natural gas and hydrogen are flammable gases and are potentially dangerous products. Any accidents involving our products or other natural gas, or hydrogen-based products could materially impede widespread market acceptance and demand for our engines and fuel systems. In addition, we may be subject to a claim by end-users or others alleging that they have suffered property damage, personal injury or death because our products did not perform adequately. Such a claim could be made whether or not our products perform adequately under the circumstances. From time to time, we may be subject to product liability claims in the ordinary course of business, and we carry a limited amount of product liability insurance for this purpose. However, our current insurance policies may not provide sufficient or any coverage for such claims, and we cannot predict whether we will be able to maintain our insurance coverage on commercially acceptable terms.
Natural gas, hydrogen, and products that use these gases entail inherent safety and environmental risks that may result in substantial liability to us.
Our operations, including our R&D and manufacturing processes, are subject to all the risks and hazards inherent to natural gas and hydrogen and products that use these gases, including equipment defects, malfunctions and failures and natural disasters, which could result in uncontrollable flows of natural gas, fires, explosions and other damages.  Although we believe that our procedures for using, handling, storing and disposing of natural gas, hydrogen and other hazardous materials comply with legally prescribed standards, we cannot completely eliminate the risk of contamination or injury resulting from natural gas, hydrogen and other hazardous materials and we may incur liability as a result of such contamination or injury. In the event of an accident, we could be held liable for damages or penalized with fines, and the liability could exceed our insurance and other resources, in which event we could incur significant costs that could have a material adverse effect upon its financial condition.
10

We could lose or fail to attract the human capital necessary to run our business.
Our success depends in large part on our ability to attract and retain key management, engineering, scientific, manufacturing, and operating human capital. As we develop additional capabilities, we may require more skilled employees. Given the highly specialized nature of our products, our employees must be highly skilled and have a sound understanding of our industry, business, or technology. Recruiting employees for the alternative fuel industry is also highly competitive. Although to date we have been successful in recruiting and retaining qualified employees, there can be no assurance that we will continue to attract and retain the human capital needed for our business. The failure to attract or retain qualified employees could have a material adverse effect on our business.
Warranty claims could be higher than forecasted.
There may be a risk that the warranty accrual included in our cost of revenue is not sufficient, and we may recognize additional expenses, including those related to litigation, because of warranty claims in excess of our current expectations. Such warranty claims may necessitate a re-design, re-specification, a change in manufacturing processes, and/or recall of our products, which may have an adverse impact on our finances and on existing or future sales. Although we attempt to mitigate against these risks through our sales and marketing initiatives and our product development, quality assurance, support and service programs, there can be no assurance that such initiatives and programs are adequate or that sales of our commercial products will continue to grow and contribute financially. Even in the absence of any warranty claims, a product deficiency such as a manufacturing defect or a safety issue could be identified, necessitating a product recall, which could have an adverse impact on our finances and on existing or future sales.
We may have difficulty responding to significant demand growth for our products.
As products are launched, sales may be more than we expect. During periods of quicker than anticipated expansion, we may have difficulty expanding the scope of our operations to match the increased demand. In addition, we may be required to place more reliance on our strategic partners and suppliers, some of whom may not be capable of meeting our production demands in terms of timing, quantity, quality or cost. Difficulties in effectively managing the budgeting, forecasting and other process control issues presented by any rapid expansion could harm our business, prospects, results of operations or financial condition.
We may not realize the anticipated benefits from our joint venture, investments, or acquisitions.
Our current joint venture, and any future joint venture, investment, or acquisition, could expose us to certain liabilities, including those that we fail or are unable to identify during the investment or acquisition process. In addition, joint ventures and acquisitions often result in difficulties in integration, and, if such difficulties were to occur, they could adversely affect our results. We have historically and may, in the future, seek to expand our business through acquisitions, investments and/or joint ventures. Any such transactions will be in part dependent on management's ability to identify, acquire and develop suitable acquisition targets in both new and existing markets. In certain circumstances, acceptable acquisition targets might not be available. Acquisitions, specifically, involve a number of risks including: (i) the possibility that we, as a successor owner, may be legally and financially responsible for liabilities of prior owners; (ii) the possibility that we may pay more than the acquired company or assets are worth; (iii) the additional expenses associated with completing an acquisition and amortizing any acquired intangible assets; (iv) the difficulty of integrating the operations and employees of an acquired business; (v) the challenge of implementing uniform standards, controls, procedures and policies throughout an acquired business; (vi) the inability to integrate, train, retain and motivate key employees of an acquired business; and (vii) the potential disruption of our ongoing business and the distraction of management from our day-to-day operations. These risks and difficulties, if they materialize, could disrupt our ongoing business, distract management, result in the loss of key human capital, increase expenses and otherwise have a material adverse effect on our business, results of operations and financial performance.

11

We have foreign currency risk.
Although we report in U.S. dollars, many of our operating expenses are in Canadian dollars, Euros and Renminbi. Foreign exchange gains and losses are included in the results of operations. Following the divestiture of our Light-Duty segment, which generated the majority of our Euro denominated revenues, our revenue from continuing operations is denominated in a combination of U.S. dollars, Canadian dollars, Euros, and Renminbi. A decline in the U.S dollar, Euro or Renminbi relative to the Canadian dollar could negatively impact margins and other financial results. We have not entered into foreign exchange contracts to hedge against gains and losses from foreign currency fluctuations.
We are at risk of cyber based attacks.
Our information technology systems serve an important role in the operation of our business. We rely on various technologies to operate our production facilities, interact with customers, vendors, and employees and to report on our business. Interruption, failure or unsuccessful implementation and integration of our information technology systems could result in material and adverse impacts on our financial condition, operations, sales, and reputation and could also result in damage to our operations. Our information technology systems and networks could be interrupted or fail due to a variety of causes, such as natural disaster, fire, power outages, vandalism, or cyber-based attacks. Subsequent to the fiscal year ended 2025, during the first quarter of 2026, we experienced a ransomware incident involving unauthorized access to certain information systems and certain customer and personal data. While remediation actions are ongoing and, as of the date of this Form 20-F, we do not believe the incident has had a material impact on us, including our operations, business strategy, results of operations, or financial condition, we may incur further costs and liabilities arising from this incident. Any future cybersecurity incident, including a recurrence, could result in operational disruptions, remediation costs, legal claims, regulatory investigations or enforcement actions, reputational harm, and adverse effects on our business, operations, financial condition, results of operations and cash flows. Although to date we have not experienced any material losses relating to cyber risks, there can be no assurance that we will not incur such losses in the future. Our Information Technology leadership continues to develop and enhance internal controls, policies and procedures designed to protect systems, servers, computers, software, data and networks from attack, damage, or unauthorized access. As cyber threats continue to evolve, we may be required to expend additional resources to continue to modify or enhance protective measures or to investigate and remediate any security vulnerabilities.
Legal, Regulatory and Other Related Risks
Risks with anti-corruption laws could have a material adverse effect on our reputation and results of operations.
Our operations are governed by, and involve interactions with, many levels of government in numerous countries. We are required to comply with anti-corruption and anti-bribery laws, including the Canadian Corruption of Foreign Public Officials Act (the "CFPOA") and the U.S. FCPA, as well as similar laws in the countries in which we conduct business. In recent years, the U.S. Department of Justice, the SEC, and the Royal Canadian Mounted Police have brought an increasing number of FCPA and CFPOA enforcement cases for non-compliance, many resulting in very large fines, penalties and deferred criminal prosecutions. A company may be liable for violations by its employees, contractors, and third-party agents. Our Code of Conduct, Anti-Bribery and Corruption policies and programs mandate compliance with anti-bribery and corruption laws. Notwithstanding these policies and programs, there can be no assurance that all employees and third-party intermediaries working on our behalf will comply with anti-bribery and corruption laws, which would result in significant penalties, fines and/or sanctions imposed on us, and/or have a material adverse effect on our operations.
We could become involved in legal proceedings and commercial or contractual disputes, which could have a material adverse effect on our business, results of operations and financial condition.
From time to time, we may be involved in proceedings or disputes with other parties arising in the ordinary course of business that may result in litigation. If we are unable to resolve these disputes favourably, it may have a material adverse impact on the financial condition, cash flow and results of our operations. Such proceedings or disputes are typically claims that arise in the ordinary course of business, including, without limitation, commercial or contractual disputes, and other disputes with customers and suppliers, joint venture parties, intellectual property matters, tax matters and employment matters. The outcome with respect to outstanding, pending or future proceedings cannot be predicted with certainty and may be determined adversely to us and could have a material adverse effect on our assets, liabilities, business, financial condition and results of operations. Even if we prevail in any such legal proceedings, the proceedings could be costly and time-consuming and may divert the attention of management and key personnel from business operations, which could have an adverse effect on our financial condition.
12

We depend on our intellectual property and our failure to protect that intellectual property could adversely affect our future growth and success.
Failure to protect our existing and future intellectual property rights could seriously harm our business and prospects and may result in the loss of our ability to exclude others from practicing our technology. If we do not adequately ensure our ability to use certain technology, we may have to pay others for the right to use their intellectual property, pay damages for infringement or misappropriation and/or be enjoined from using such intellectual property. Our patents do not guarantee us the right to practice our technologies if other parties' own intellectual property rights are necessary to practice such technologies. Our patent position is subject to complex factual and legal issues that may give rise to uncertainty as to the validity, scope and enforceability of a particular patent. As is the case in many other industries, the web of intellectual property ownership in our industry is complicated and, in some cases, it is difficult to define with precision where one property begins and another ends.
We also seek to protect our proprietary intellectual property, including intellectual property that may not be patented or patentable, in part by confidentiality agreements and, if applicable, inventors' rights agreements with our strategic partners and employees. There can be no assurance that these agreements will not be breached, that we will have adequate remedies for any breach or that such persons or institutions will not assert rights to intellectual property arising out of these relationships.
Certain intellectual property has been licensed to us from third parties who may also license such intellectual property to others, including our competitors. If necessary or desirable, we may seek further licenses under the patents or other intellectual property rights of others. However, we can give no assurances that we will obtain such licenses or that the terms of any offered licenses will be acceptable to us. The failure to obtain or renew a license from a third party for intellectual property we use at present could cause us to incur substantial costs and to suspend the manufacture or shipment of products or our use of processes requiring such intellectual property.
We could become engaged in intellectual property litigation or disputes that may negatively affect our business.
Claims may be made by third parties that the practice of our technology infringes upon patents owned by those third parties. Although we have seen no valid basis for any claims, as our business grows, parties may attempt to take advantage of that growth and assert claims and demands for compensation. Our response to such claims will be commensurate with the seriousness of the allegations, their potential effect on our business and the strength of our position. We will examine a range of options, from formal legal action to obtaining a declaratory judgment of non-infringement, to the initiation of design changes. We intend to vigorously defend our intellectual property.
We are currently engaged in material intellectual property litigation against others who we believe are infringing on our rights. In addition, we could become subject to lawsuits in which it is alleged that we have infringed the intellectual property rights of others or in which the scope, validity and enforceability of our intellectual property rights is challenged. Our involvement in intellectual property litigation or disputes could be time consuming and result in significant expense to us, diversion of resources, and delays or stoppages in the development, production and sales of products or intellectual property, whether or not any claims have merit, or such litigation or disputes are resolved in our favor. Any such result could require the expenditure of substantial time and other resources and could have a material adverse effect on our business and financial results.
Economic sanctions may impact the business of certain of our foreign subsidiaries and our joint venture.
Some of our foreign subsidiaries, our joint venture, or future acquisitions may sell products to customers in countries whose companies, governments, and people may be subject to sanctions, tariffs, and embargoes imposed by, including but not limited to, the U.S., Canadian, and European Union governments. Although these sanctions, tariffs, and embargoes may not prohibit those foreign subsidiaries and joint ventures from selling products and providing services in these countries, they may prohibit us and our domestic subsidiaries and joint ventures, as well as employees of our foreign subsidiaries and joint ventures who are US, Canadian, and European citizens, from participating in, approving or otherwise facilitating any aspect of the business activities in those countries. The constraints on our ability to have U.S., Canadian or European persons, including our senior management, provide managerial oversight and supervision over sales in embargoed countries may negatively affect the financial or operating performance of such business activities. We routinely monitor changes in economic sanctions laws and adapt our procedures to remain in compliance with such laws.
13

We could become liable for environmental damages resulting from our research, development or manufacturing activities.
The nature of our business and products exposes us to potential claims and liability for environmental damage, personal injury, loss of life, and damage to or destruction of property, including potentially for claims due to the release of methane and other greenhouse gases (GHG). Our business is subject to numerous laws and regulations that govern environmental protection and human health and safety. These laws and regulations have changed frequently in the past and it is reasonable to expect additional and more stringent changes in the future. Our operations may not comply with future laws and regulations, including those related to climate change, and we may be required to make significant unanticipated capital and operating expenditures. If we fail to comply with applicable environmental laws and regulations, governmental authorities may seek to impose fines, penalties, compliance orders, injunctions, civil liability, or criminal sanctions, or to revoke or deny the issuance or renewal of operating permits, and private parties may seek damages from us. Under those circumstances, we might be required to curtail or cease operations, conduct site remediation or other corrective action, or pay substantial damage claims. In addition, depending on the nature of the claim, our current insurance policies may not provide sufficient or any coverage for such claims.
Failure to comply with privacy laws to which we are subject could harm us.
Our privacy policy is posted on our website, and any failure by us to comply with it or with privacy, data protection or security laws or regulations to which we are subject, that relate to the collection, use, retention, security and transfer of personally identifiable information could result in regulatory or litigation-related actions against us, legal liability, fines, damages, ongoing audit requirements and other significant costs. Substantial expenses and operational changes may be required in connection with maintaining compliance with such laws, and certain emerging privacy laws are still subject to a high degree of uncertainty as to their interpretation and application.
Additional or higher tariffs may impact the demand for our products.
Increases in trade conflicts and protectionism, as well as political developments, could result in increased and additional implementation of tariffs. This may cause volatility in the demand and pricing of our products in the markets we serve, with concerns over supply chain disruptions leading to fluctuations in purchasing patterns. Additionally, ongoing changes and uncertainty in trade policies have contributed to volatility in the U.S. dollar exchange rate, which in turn impacts our sales and cost structure by influencing raw material costs, pricing competitiveness, and cross-border trade dynamics. To the extent such U.S. tariffs have and may continue to lead to retaliatory tariffs on imports of United States products, or otherwise cause an increase in the prices of the inputs we use in our operations or diminished availability of such inputs, our ability to maintain our current cost structure or level of operations may be materially and adversely affected. In addition, general or specific tariffs having an adverse effect on our customers may significantly reduce the demand for our products. Any of these risks may result in, among other things, us experiencing reduced production levels, higher costs and lower operating margins, any of which could have a material and adverse effect on our financial position, results of operations and liquidity. If these or any other of the risks contemplated by this Form 20-F manifest themselves in a manner that has a disproportionate effect on our operations, our financial condition and results of operations may be materially and adversely affected.
Risks Related to our Common Shares
Our Common Share price may fluctuate.
The stock market in general, and the market prices of securities of technology companies in particular, can be extremely volatile, and fluctuations in our Common Share price may be unrelated to our operating performance. Our Common Share price has been and could in the future be subject to significant fluctuations in response to many factors, including: actual or anticipated variations in our results of operations; the addition or loss of customers; announcements of technological innovations; new products or services by us or our competitors; changes in financial estimates or recommendations by securities analysts; conditions or trends in our industry; our announcements of significant acquisitions, strategic relationships, joint ventures or capital commitments; additions or departures of key employees; general market conditions; and other events or factors, many of which may be beyond our control. Therefore, you bear the market risk associated with fluctuations in the price of our Common Shares. Unstable market conditions could cause the trading price of our Common Shares to decline or fluctuate in a rapid or unpredictable manner and, in that case, investors could lose all or part of their investment in such securities.
14

There can be no assurance that the current trading price will be maintained, and it is possible that our Common Share price could drop significantly. In addition, future sales of substantial amounts of our Common Shares, or securities convertible into or exchangeable for shares of our Common Shares, into the public market, or the perception that those sales could occur, could negatively affect the market price of our Common Shares and our ability to raise capital in the future. An issuance of additional Common Shares could also dilute the percentage ownership interest and corresponding voting power of the existing holders of such securities. Holders of our Common Shares are not entitled to pre-emptive rights or other protections against dilution.
Litigation, including litigation due to Common Share price volatility or other factors, could cause us to incur substantial costs and divert our management's time and attention.
From time to time, we may become involved in, or become liable for legal, contractual, and other claims by various parties, including customers, suppliers, former employees, class action plaintiffs and others, including litigation related to the volatility of our Common Shares and investigations or reviews by regulatory bodies. If we become involved in significant litigation, investigations or reviews by regulatory bodies or other proceedings in the future, it could result in substantial costs and diversion of management’s attention and resources and could adversely affect our financial condition, business, and prospects. On an ongoing basis, we attempt to assess the likelihood of any adverse judgments or outcomes to these proceedings or claims, although it is difficult to predict final outcomes with any degree of certainty. Except as disclosed from time to time in our financial statements, we do not believe that any of the proceedings or claims to which we are party will have a material adverse effect on our financial position; however, we cannot provide any assurance to this effect.
We do not currently pay and do not anticipate paying any cash dividends on our Common Shares in the near future; therefore, our shareholders may not be able to receive a return on their Common Shares until they sell them.
We have never paid or declared any cash dividends on our Common Shares. We do not anticipate paying any cash dividends on our Common Shares in the foreseeable future because, among other reasons, our loan agreement restricts our ability to pay dividends, and we currently intend to retain any future earnings to finance our business. The future payment of dividends will be dependent on factors such as cash on hand and achieving profitability, the financial requirements to fund growth, our general financial condition, and other factors our board of directors may consider appropriate in the circumstances. Until we pay dividends, which we may never do, our shareholders will not be able to receive a return on their Common Shares unless they sell them.
If we are characterized as a passive foreign investment company ("PFIC"), U.S. holders may be subject to adverse U.S. federal income tax consequences.
A non-U.S. corporation generally will be treated as a PFIC for U.S. federal income tax purposes in any taxable year if either (1) at least 75% of its gross income for such year is passive income (such as interest income) or (2) at least 50% of the value of its assets (generally based on an average of the quarterly values of the assets) during such year is attributable to assets that produce or are held for the production of passive income. Based on the value of our assets, including goodwill, and the composition of our income, assets and operations for the taxable year ended December 31, 2025, we do not believe that we were a PFIC for U.S. federal income tax purposes for that taxable year. However, we must determine our PFIC status annually based on tests which are factual in nature, and our status in future years will depend on our income, assets and operations in those years. The application of the PFIC rules is subject to uncertainty in several respects, and determinations of value are inherently factual and subject to different interpretations. Changes in the composition of our income or assets, the market value of our Common Shares, and the market value of our assets may cause us to become a PFIC. Accordingly, there can be no assurance that we were not a PFIC for any previous taxable year (including our taxable year ended December 31, 2025) or that we will not be a PFIC for the current taxable year or any future taxable year. Moreover, if we are a PFIC for any taxable year during which a U.S. Holder (as defined in “Taxation — U.S. Federal Income Tax Considerations --Definition of a U.S. Holder”) holds our Common Shares, such U.S. Holder may be subject to adverse tax consequences. Each prospective investor is strongly urged to consult its tax advisors regarding the application of these rules to such investor's particular circumstances. See “Taxation — U.S. Federal Income Tax Considerations”.
If a U.S. person is treated as owning at least 10% of our shares, such holder may be subject to adverse U.S. federal income tax consequences.
If a U.S. person is treated as owning (directly, indirectly or constructively) at least 10% of the value or voting power of our shares, such person will be treated as a “United States shareholder” with respect to each controlled foreign corporation
15

(“CFC”) in our group (if any). Because our group includes one or more United States subsidiaries, certain of our non-U.S. subsidiaries could be treated as CFCs for taxable years beginning before January 1, 2026, regardless of whether or not we are treated as a CFC. However, for taxable years beginning after December 31, 2025, as a result of certain changes enacted by the One Big Beautiful Bill Act of 2025, our non-U.S. subsidiaries generally will not be treated as CFCs, and no U.S. Holder will be treated as a United States shareholder with respect to such non-U.S. subsidiaries, solely by reason of the inclusion of one or more U.S. subsidiaries in our group. A United States shareholder of a CFC generally will be required to annually report and include in its U.S. taxable income its pro rata share of “Subpart F income,” “net CFC tested income” (or “global intangible low taxed income” for taxable years beginning before January 1, 2026 and investments in U.S. property by the CFC, whether or not we make any distributions. An individual that is a United States shareholder with respect to a CFC generally would not be allowed certain tax deductions or foreign tax credits that would be allowed to a United States shareholder that is a corporation. A failure to comply with these reporting obligations may subject a United States shareholder to significant monetary penalties and may prevent the statute of limitations with respect to a United States shareholder’s U.S. federal income tax return for the year for which reporting was due from starting. Furthermore, we cannot provide any assurances that we will have sufficient information to assist investors in determining whether we or any of our subsidiaries are treated as a CFC or whether such investor is treated as a United States shareholder with respect to any such CFCs. We also cannot guarantee that we will be in a position to furnish to any United States shareholder information that may be necessary to comply with the aforementioned reporting and tax payment obligations. U.S. investors should consult their own advisors regarding the potential application of these rules to an investment in our Common Shares.

As a foreign private issuer, we are subject to different U.S. securities laws and rules than a domestic U.S. issuer, which may limit the information publicly available to our U.S. shareholders.
We are a foreign private issuer under applicable U.S. federal securities laws and, therefore, we are not required to comply with all the periodic disclosure and current reporting requirements of the U.S. Securities Exchange Act of 1934, as amended (the "Exchange Act") and related rules and regulations. We file our annual report with the SEC on Form 20-F, which differs in certain respects from the reports that U.S. domestic issuers file on Forms 10-K, 10-Q, and 8-K. We are not required to file quarterly reports on Form 10-Q or current reports on Form 8-K and instead furnish certain interim reports and press releases to the SEC on Form 6-K. In addition, as a Canadian foreign private issuer, our officers, directors, and principal shareholders are subject to different insider reporting requirements and reporting timeframes than those applicable to officers, directors and principal shareholders of U.S. domestic issuers. Consequently, information regarding purchases or sales of our common shares by such persons may not be available to shareholders on the same basis or within the same timeframes as would be the case for a U.S. domestic issuer. In addition, as a foreign private issuer, we are exempt from the proxy rules under the Exchange Act and Regulation FD. In addition, subject to the applicable rules of our listing exchange, we may follow certain home-country corporate governance practices in lieu of the requirements of U.S. securities exchanges. As a result of these differences, you may receive less or different information about us and at different times than you would receive from a U.S. domestic issuer.
We may lose our foreign private issuer status in the future, which could result in significant additional costs and expenses to us.
To maintain our status as a foreign private issuer, a majority of our Common Shares must be owned of record by non-residents of the U.S. unless we also satisfy one of the additional requirements necessary to preserve this status. We may in the future lose our foreign private issuer status if a majority of our Common Shares are held in the U.S. and we fail to meet the additional requirements necessary to avoid loss of foreign private issuer status. The regulatory and compliance costs to us under U.S. federal securities laws as a U.S. domestic issuer may be significantly more than the costs we incur as a Canadian foreign private issuer eligible to file on Form 20-F. If we are not a foreign private issuer, we would not be eligible to use Form 20-F and would instead be required to file annual reports on Form 10-K, quarterly reports on Form 10-Q, and current reports on Form 8-K with the SEC, which impose more detailed and extensive disclosure obligations than those applicable to a foreign private issuer. In addition, we may lose the ability to rely upon exemptions from corporate governance requirements of the Nasdaq Listing Rules that are available to foreign private issuers.
U.S. investors may not be able to obtain enforcement of civil liabilities against us.
The enforcement by investors of civil liabilities under the U.S. federal or state securities laws may be affected adversely by the fact that we are governed by the Business Corporations Act (Alberta), a statute of the Province of Alberta, Canada, that the majority of our officers and directors and some of the experts named in this Form 20-F, are residents of Canada or otherwise reside outside the U.S., and that all, or a substantial portion of their assets and a substantial portion of our assets, are located outside the U.S. It may not be possible for investors to effect service of process within the U.S. on certain of our directors and officers or the experts named in this Form 20-F or enforce judgments obtained in the U.S. courts against us,
16

certain of our directors and officers or the experts named in this Form 20-F based upon the civil liability provisions of U.S. federal securities laws or the securities laws of any state of the U.S.
There is some doubt as to whether a judgment of a U.S. court based solely upon the civil liability provisions of U.S. federal or state securities laws would be enforceable in Canada against us, our directors and officers or the experts named in this Form 20-F. There is also doubt as to whether an original action could be brought in Canada against us or our directors and officers or the experts named in this Form 20-F to enforce liabilities based solely upon U.S. federal or state securities laws.

B. Business Overview
Westport is a technology and innovation company connecting synergistic technologies to power a cleaner tomorrow. As a supplier of affordable, alternative fuel, low-emissions transportation technologies, the Company designs, manufactures, and supplies advanced components and systems that enable the transition from traditional fuels to alternative energy solutions.
Westport's technologies support a wide range of alternative fuels – including natural gas, renewable natural gas, and hydrogen – enabling OEMs and commercial transportation industries to meet performance demands, regulatory requirements, and climate targets in a cost-effective way. With decades of expertise and a commitment to engineering excellence, Westport is helping our partners achieve sustainability goals—without compromising performance or cost-efficiency – making clean, scalable transport solutions a reality.

Westport is headquartered in Vancouver, Canada, with operations in Cambridge, Ontario; Calgary, Alberta; and China and Europe. With a focus on engineering, manufacturing, and supplying alternative fuel systems and components for transportation applications, Westport’s product offerings, sold under its AFS and GFI brands and through Cespira, enable the use of several alternative fuels in the transportation sector that provide economic and/or environmental advantages as compared to diesel, gasoline, or battery powered electric vehicles.

Our portfolio includes our High-Pressure Controls segment sold under the AFS and GFI brands and a 55% ownership in Cespira, a joint venture with Volvo. Our High-Pressure Controls segment designs, develops, and produces components, including pressure regulators, valves, filters, electronic control units ("ECUs") and high-pressure hydrogen components for transportation and industrial applications. We partner with fuel cell, hydrogen engine and alternative fuel engine manufacturers offering versatile solutions that serve a variety of fuel types. Cespira launched in 2024 and is committed to advancing the development and commercialization of Cespira's HPDI™ fuel system, a fully OEM-integrated gaseous fuel system that enables heavy-duty diesel engines to operate with a range of alternative fuels including natural gas, RNG, hydrogen and others without any performance or efficiency compromises relative to the base diesel engine platform. As part of Westport and Cespira's portfolio of solutions, Cespira's LNG HPDI 2.0 fuel system is on the road today and is a complete system offering OEMs the flexibility to differentiate their natural gas product lines easily while also maintaining maximum commonality with their conventional diesel fueled products.
Business Segments
Westport develops and supplies advanced alternative‑fuel systems, components, and technologies that enable global transportation and industrial customers to affordably reduce emissions and transition toward cleaner mobility solutions. Our technologies, products, and services are sold under our established brands and form the foundation for sustainable growth in both existing and emerging markets worldwide. We operate through the following segments:

Cespira
In June 2024, Westport and Volvo entered into a series of joint venture agreements (collectively, the "JV Agreement"), to establish Cespira, focused on promoting, developing, and commercializing the HPDI fuel system technology (see Material Contracts – Joint Venture Governance Agreements). Under the terms of the agreement, Westport owns a 55% equity interest in Cespira, while Volvo owns 45%. The JV prioritizes scaling the HPDI fuel system and supporting the global transition to carbon-neutral, internal combustion engine technologies, particularly within heavy-duty, long-haul trucking, where multiple propulsion technologies are required to achieve substantial decarbonization. Cespira designs, assembles, and supplies LNG HPDI 2.0 fuel systems, related components, and engineering services to engine manufacturers and commercial vehicle OEMs. The fully integrated LNG HPDI 2.0 fuel systems enable diesel engines to operate predominantly on alternative gaseous fuels - such as renewable natural gas (RNG) - while maintaining equivalent power, torque, and fuel efficiency relative to conventional compression ignition engines fueled with diesel fuel. This can provide a
18

cost-effective pathway to meaningful greenhouse gas reductions. The JV is also advancing the application of HPDI fuel systems for hydrogen and other alternative fuels in internal combustion engines, expanding its relevance to future decarbonization strategies.
Over the past three fiscal years, HPDI has remained Cespira’s (and previous to Cespira’s formation, Westport’s) primary heavy‑duty on‑engine decarbonization offering.

Cespira is currently working on the advancement of a hydrogen (H2) HPDI fuel system, adapting HPDI technology to operate on gaseous hydrogen. Publicly announced development work is ongoing, including system‑level engineering, prototype integration, and performance validation.

High-Pressure Controls
The High-Pressure Controls segment designs, engineers, manufacturers, and supplies components for transportation and industrial applications, using gaseous fuels such as hydrogen. This segment represents Westport's off-engine product portfolio, supplying regulators, valves, ECUs, pressure components, and related engineered solutions to OEM and Tier-1 customers worldwide. These technologies support fuel-cell vehicles, hydrogen fueled internal combustion engines, and natural gas mobility platforms.
Westport's High-Pressure Controls segment, with its GFI-branded products, has decades of engineering expertise in developing high‑quality and often customized components tailored for global automotive, truck, bus, rail, construction, and industrial OEMs. The business is positioned at the forefront of the clean‑energy transition, with solutions supporting both current alternative‑fuel deployment and hydrogen‑powered mobility.

Through our GFI‑branded operations, with manufacturing facilities in Canada and China, we deliver components used in passenger vehicles, buses, mid‑duty and heavy‑duty trucks, rail applications, construction and industrial equipment.

New products & developments:
•Ongoing development of next‑generation hydrogen‑rated regulators.
•Expansion of electronics and controls, including updated ECUs and calibration software supporting broader fuel‑system architectures.
•Multiple components for hydrogen internal combustion engines and fuel‑cell vehicles remain in active development phases with global OEM partners.

Heavy-Duty OEM
The Heavy-Duty OEM segment represents historical results from our heavy-duty business for the period January 1, 2024, until the formation of the Cespira joint venture which occurred on June 3, 2024. Subsequently, the Heavy-Duty OEM segment reflected activity from a transitional services agreement with Cespira, which was put in place primarily to support the JV in the short-term as the organization established its manufacturing operations. On June 30, 2025, the transitional services agreement (TSA) ended.
2. Principal Markets & Revenue Breakdown (Last Three Years)

Westport competes across a diverse set of global transportation and industrial markets that are transitioning toward lower‑carbon propulsion systems. Our revenue streams reflect the varied applications of Cespira's HPDI and high‑pressure components and controls portfolios.

•Heavy‑duty long‑haul trucking: A core market for HPDI fuel systems, where operators demand diesel‑equivalent performance combined with significant emissions reduction. This segment represents the largest commercial opportunity for Cespira’s LNG and hydrogen HPDI offerings.
•Medium‑duty and vocational transport: Including regional delivery, refuse, governmental, and utility vehicles adopting gaseous‑fuel solutions to meet evolving emissions standards.
•Passenger vehicles: GFI‑branded components provide OEMs with validated gaseous‑fuel solutions.
•Industrial, construction, and off‑road equipment: Markets requiring high‑pressure components for forklifts, construction machinery, power systems, mining equipment, and agricultural machinery.
•Rail and specialty applications: Niche applications where hydrogen and natural‑gas fuels provide significant emissions‑reduction benefits in controlled‑route operations.

Over the last three fiscal years, our revenues have aligned with the structure of our reportable segments:
•Cespira (HPDI fuel system technology, a heavy‑duty on‑engine solution)
•High‑Pressure Controls (components and subsystems)
19

•Heavy‑Duty OEM (TSA activities)

Geographically, Westport generates revenue from North America, Europe, and Asia‑Pacific, with growing penetration in emerging markets adopting gaseous‑fuel mobility solutions. Refer to Note 17 in our consolidated financial statements included in this annual report Form 20-F for our revenue by geographic region.

3. Seasonality of Business

Demand in several of our transportation‑related markets exhibits moderate seasonality, influenced by OEM production cycles, regulatory introduction dates, and fleet procurement patterns. Hydrogen and natural‑gas component sales may fluctuate based on regional adoption incentives and infrastructure availability. Heavy‑duty OEM order cycles may also reflect freight and logistics seasonality.

4. Sources and Availability of Raw Materials

Our manufacturing processes rely on metals, precision‑machined components, electronics, seals, and specialized high‑pressure materials sourced from global suppliers. While most raw materials are available from multiple vendors, certain high‑precision, hydrogen‑rated, and HPDI‑specific components require qualified suppliers with specialized manufacturing capabilities. Prices for metals and electronics can exhibit volatility based on global supply‑chain disruptions, commodity cycles, and geopolitical factors. We mitigate this risk through multi‑source strategies, long‑term supply arrangements, and inventory management.

5. Marketing Channels & Sales Methods

Westport employs a multi‑channel, engineering‑driven market approach, including:
•Direct OEM relationships: Our largest revenue streams arise from long‑term supply programs with global heavy‑duty truck OEMs, bus manufacturers, and industrial‑equipment producers.
•Engineering‑integration engagements: HPDI and advanced hydrogen systems require deep collaboration with OEM engineering teams during engine development, validation, calibration, and certification.
•Tier‑1 and Tier‑2 supply agreements: GFI‑branded components integrate into broader propulsion systems built by leading hydrogen‑ICE and fuel‑cell system providers.

Sales cycles are long‑duration and engineering‑intensive, often spanning multi‑year development programs. Pricing often reflects multi‑year contractual frameworks involving volume commitments, engineering services, and validation milestones.

6. Dependence on Patents, Licenses & Material Contracts

Westport’s competitive position relies on our portfolio of patents and trade secrets relating to HPDI combustion, high‑pressure fuel delivery, hydrogen‑rated components, control algorithms, and electronic management systems.

The Cespira joint venture and associated licensing, technology‑transfer, and supply agreements are material to our long‑term HPDI business.

The Company is also party to industrial contracts with OEMs and Tier‑1 suppliers relating to component development, validation, and supply. These contractual and intellectual‑property foundations are critical to our business and profitability.

7. Basis for Competitive Position Statements

Statements about Westport’s competitive position are based on:
•Our status as the only commercial provider of HPDI fuel system technology enabling diesel‑like performance using LNG/RNG or hydrogen.
•Our decades‑long presence in hydrogen and natural‑gas components through the GFI brand.
•Publicly disclosed OEM collaborations, customer deployments, component performance specifications, and industry market‑share assessments from independent market participants.

Such statements reflect the Company's evaluation of publicly available data and customer‑validated performance metrics.

8. Government Regulations & Regulatory Bodies

Our products and operations are subject to environmental, emissions, safety, and fuel‑certification standards administered by regulatory agencies globally, including:
•U.S. Environmental Protection Agency (EPA)
•California Air Resources Board (CARB)
•European Union regulatory bodies (e.g., UNECE)
20

•Transport Canada

Item 5. Operating and Financial Review and Prospects
A. Operating Results
OVERVIEW OF FINANCIAL RESULTS FOR 2025
Revenues for the year ended December 31, 2025 decreased by 43% to $23.3 million compared to $40.7 million in the prior year. The decrease was primarily driven by the end of the transitional service agreement between Westport and Cespira to provide inventory and contract manufacturing in Q2 2025 in our Heavy-Duty OEM segment, resulting in a decrease $16.3 million compared to prior year. The slowdown in the hydrogen industry, beginning early in 2025, along with the move of our manufacturing capability from Italy to Canada and China in the third and fourth quarters of 2025, negatively impacted sales in our High-Pressure Controls segment in 2025.
Cespira's revenue for the year ended December 31, 2025 was $77.4 million, an increase of $34.4 million, or 80% compared to prior year. Cespira continued its growth in 2025, for more information on Cespira's results refer to "Selected Cespira Statement of Operations information" within this MD&A.
We reported a net loss from continuing operations of $29.6 million for the year ended December 31, 2025 compared to a net loss from continuing operations of $31.3 million for the prior year. The net change was primarily the result of:
•Lower operating expenditures across research and development, and selling, general and administrative expenses.
•Favorable change in foreign exchange rates resulting in a net gain in 2025.
•In the prior year, a gain on deconsolidation of $15.2 million on the formation of Cespira reduced the net loss from continuing operations, without the gain, the improvement in our current year net loss from continuing operation compared to prior year would be greater.
•Partially offset by our loss from investments accounted for by the equity method of $15.8 million in 2025 compared to a loss of $6.7 million in the prior year.
Cash and cash equivalents were $27.2 million as at December 31, 2025. Cash used in operating activities from continuing operations during the year was $14.2 million, primarily driven by our operating loss from continuing operations. Cash provided by investing activities included the sale of our Light-Duty segment, partially offset by capital contributions to Cespira and the purchase of property, plant, and equipment for the new facilities in Canada and China. Cash used in financing activities from continuing operations was related to net debt repayments of $4.0 million in the year, which included a short-term loan from the Purchaser of $5.8 million in July 2025.
We reported negative adjusted EBITDA of $17.3 million (see "Non-GAAP Measures" section in this annual report Form 20-F) during the year ended December 31, 2025 as compared to negative adjusted EBITDA of $11.4 million in the prior year.

The decrease in revenue for the year ended December 31, 2025 compared to the prior year period were primarily driven by the general slowdown in hydrogen infrastructure development that began in the first half of 2025, leading to a slower adoption of automotive and industrial applications powered by hydrogen. In Q3 2025, we moved our manufacturing capacity from Italy to our new facilities in Canada and China, which required shutting down our operations. In late Q4 2025, we resumed selling products to our customers to meet the backlogged demand from the aforementioned shutdown. In early 2026, we announced start of production at both facilities and expect output and efficiency to increase over the year.

Foreign exchange gains and losses reflect net realized gains and losses on foreign currency transactions and net unrealized gains and losses on our net U.S. dollar denominated monetary assets and liabilities in our Canadian operations that were mainly comprised of cash and cash equivalents, accounts receivable and accounts payable. In addition, we have foreign exchange exposure on Euro denominated monetary assets and liabilities where the functional currency of the subsidiary is not in Euro. For the year ended December 31, 2025, we recognized a foreign exchange gain of $5.4 million compared to a foreign exchange loss of $6.2 million for the year ended December 31, 2024. The gain recognized in the current year primarily relates to unrealized foreign exchange gain resulting from the remeasurement of U.S. dollar denominated debt in our Canadian legal entities.
Depreciation and amortization for the years ended December 31, 2025 and December 31, 2024 were $0.7 million and $2.2 million, respectively. Depreciation and amortization decreased year-over-year, primarily driven by the transition of the HPDI business into Cespira on June 3, 2024.

NON-GAAP FINANCIAL MEASURES & RECONCILIATIONS
In addition to the results presented in accordance with U.S. GAAP, we used EBIT, EBITDA, Adjusted EBITDA, gross margin, net working capital, and other non-current liabilities (collectively, the “Non-GAAP Measures") throughout this MD&A. We believe these non-GAAP measures provide additional information that is useful to stakeholders in understanding our underlying performance and trends through the same financial measures employed by our management. We believe that EBIT, EBITDA, and Adjusted EBITDA are useful to both management and investors in their analysis of our ability to generate liquidity by producing operating cash flow to fund working capital needs, service debt obligations and fund capital expenditures. Management also uses these non-GAAP measures in its review and evaluation of the financial performance of the Company. EBITDA is also frequently used by stakeholders for valuation purposes whereby EBITDA is multiplied by a factor or "EBITDA multiple" that is based on an observed or inferred relationship between EBITDA and market values to determine the approximate total enterprise value of a company. We believe these non-GAAP financial measures also provide additional insight to stakeholders as supplemental information to our U.S. GAAP results and as a basis to compare our financial performance period-over-period and to compare our financial performance with that of other companies. We believe that these non-GAAP financial measures facilitate comparisons of our core operating results from period to period and to other companies by, in the case of EBITDA, removing the effects of our capital structure (net interest income on cash deposits, interest expense on outstanding debt and debt facilities), asset base (depreciation and amortization) and tax consequences. Adjusted EBITDA provides this same indicator of Westport's EBITDA from operations and removing such effects of our capital structure, asset base and tax consequences, but additionally excludes any unrealized foreign exchange gains or losses, stock-based compensation charges and other one-time impairments and costs that are not expected to be repeated in order to provide greater insight into the cash flow being produced from our operating business, without the influence of extraneous events. Readers should be aware that non-GAAP measures have no standardized meaning under U.S. GAAP and accordingly may not be comparable to the calculation of similar measures by other companies. Non-GAAP measures are intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with U.S. GAAP.

Liquidity & Capital Resources    
The Company believes that it has considered all possible impacts of known events arising from the risks discussed elsewhere in this annual report Form 20-F related to supply chain, and fuel prices in the preparation of the consolidated financial statements for the year ended December 31, 2025. However, changes in circumstances due to the forementioned risks could affect our judgments and estimates associated with our liquidity and other critical accounting assessments.
For the year ended December 31, 2025, the Company continues to sustain operating losses and use cash to support its business activities. Cash used in operating activities from continuing operations was $14.2 million for the year ended December 31, 2025 and was primarily driven by our operating loss from continuing operations and changes in working capital.
As at December 31, 2025, we had cash and cash equivalents of $27.2 million and debt of $2.9 million. Based on the Company's projected capital expenditures, debt servicing obligations and operating requirements under its current business plan, the Company is projecting its cash and cash equivalents will not be sufficient to fund its operations through the next twelve months from the date of the issuance of this annual report. These conditions raise substantial doubt about Westport's ability continue as a going concern within one year after the date of this annual report is issued.
31

We plan to improve our liquidity position by raising funds from public markets, borrowing debt, or other financing alternatives. These plans are not final and are subject to market and other conditions not in our control. As such, there can be no assurances that Westport will be successful in obtaining sufficient funding. Accordingly, we concluded under the accounting standards that these plans do not alleviate the substantial doubt about Westport's ability to continue as a going concern.
Our cash and cash equivalents position increased by $12.4 million to $27.2 million at December 31, 2025 compared to $14.8 million at December 31, 2024. The increase in cash was primarily driven by the sale of our Light-Duty segment, partially offset by cash used in our operating activities and debt repayments.

Cash Flow from Operating Activities from Continuing Operations

For the year ended December 31, 2025, net cash used in operating activities from continuing operations was $14.2 million compared to net cash used in operating activities from continuing operations of $5.8 million for the year ended December 31, 2024, an $8.4 million increase in net cash used in operating activities. The increase in net cash used in operating activities for the current year was primarily driven by the change in our working capital in the prior year after the formation of the joint venture in June 2024, partially offset by the lower operating losses in the current year.

Cash Flow from Investing Activities from Continuing Operations

For the year ended December 31, 2025, our net cash provided by investing activities from continuing operations was $15.8 million compared to net cash provided by investing activities from continuing operations of $16.3 million for the year ended December 31, 2024. The decrease in net cash provided by investing activities were primarily driven by purchases of property, plant and equipment of $2.7 million and capital contributions to Cespira of $21.7 million in the year ended December 31, 2025, partially offset by the sale of the Light-Duty segment. In the prior year, we received proceeds from sale of investments which included cash proceeds of $27.3 million from Volvo for the purchase of a 45% ownership interest in Cespira as part of the formation of the joint venture.

The Company and its joint venture partner, Volvo, have jointly committed to funding $20.0 million to Cespira for fiscal year 2026. Our expected portion of capital contributions to Cespira is 55% or $11.0 million. Compared to our 2025 annual capital contributions of $21.7 million, this is a significant reduction in required funding reflecting the improvement in net cash flows used in Cespira.

Cash Flow from Financing Activities from Continuing Operations

For the year ended December 31, 2025, our net cash used in financing activities was $4.0 million, compared to net cash used in financing activities of $18.7 million during the year ended December 31, 2024. On November 30, 2024, we closed our revolving financing facility with Royal Bank of Canada and reduced our use of the credit facility. In July 2025, we borrowed $5.8 million from the Purchaser for short-term liquidity as we prepared for the sale of the Light-Duty segment. We continued to repay our term loan to EDC in 2025.

C. Research and Development, Patents and Licenses
Our joint venture, Cespira, is responsible for all research and development work undertaken to advance the HPDI fuel system technology. Westport continues to work to improve the products for Westport's High Pressure Controls and Systems segment, as we strive to drive innovation, strengthen our competitive edge and position us for long-term growth.

Our intellectual property strategy is to capture, protect, and utilize our intellectual property in coordination with our business and technology plans and enable the successful commercialization of our proprietary products. Our intellectual property strategy is designed to be adaptive to our target markets in supporting the commercial launch of new products while maintaining Westport’s long-term competitive advantage. As a result, we rely on a combination of patents, trade secrets, trademarks, copyrights and contracts to protect our proprietary technology.

We use patents as the primary means of protecting our technological advances and innovations. They include proprietary claims to novel concepts embodied in our components, materials, operating techniques, and systems. We have a proactive approach to identifying, evaluating, and choosing strategic inventions to protect through the timely filing and prosecution of patent applications. Patent applications are filed in various jurisdictions internationally, which are carefully chosen based
32

on the likely value and enforceability of intellectual property rights, and to strategically protect anticipated major commercial markets.

D. Trend Information
Other than as disclosed elsewhere in this annual report on Form 20-F, we are not aware of any trends, uncertainties, demands, commitments or events that are reasonably likely to have a material adverse effect on our revenue, net loss, profitability, liquidity or capital resources, or that would render reported financial information to be not necessarily indicative of future operating results or financial conditions.

E. Critical Accounting Estimates
Our significant accounting policies are described in "Note 3. Significant accounting policies" in our consolidated financial statements included elsewhere in this annual report on Form 20-F. The preparation of these financial statements in accordance with U.S. GAAP requires us to make estimates and judgments that affect the reported amount of assets, liabilities, revenues, expenses and related disclosure of our long-term investments in Cespira. Critical accounting estimates are those that involve significant judgment or uncertainty and could materially impact our financial condition or results of operations if different assumptions or conditions were to occur.
We are not aware of any specific events or circumstances that would require updates to our estimates and judgments or require us to revise the carrying value of our assets or liabilities from what had been assumed when the financial statements were prepared. These estimates may change as new events occur and additional information is obtained. Actual results could differ materially from these estimates under different assumptions or conditions. The following represent our most critical accounting estimates.
Variable interest entities ("VIEs") and impairment of long-term investments accounted for by the equity method

We identified Cespira Canada LP and Cespira Sweden AB as VIEs, as the entities are dependent on funding from its owners. The funding and ownership interests of the entities are split on a 55/45 basis between the owners of the VIEs. The voting rights and power to exercise control is shared equally on a 50/50 basis between the owners of the VIEs. Therefore, we have determined that we are not the primary beneficiary of the VIEs. We account for our investment in VIEs for which we are not primary beneficiaries of using the equity method of accounting.

Identifying a VIE and determining the primary beneficiary of a VIE requires the use of our judgment, estimates, and assumptions including determining the most significant activities and decisions that impact the economic performance of a VIE and the beneficiary who has the power over those decisions. If events and circumstances change in a VIE, it may have a significant impact in how we account for the entity.

We evaluate our long-term investments for impairment when an investee has recognized a series of operating losses or recognizes an impairment loss in its financial statements. In such an event, we measure the fair value of the investee against its carrying amount. We estimate the fair value of our long-term investment using the expected future cash flows discounted at a rate commensurate with the risks of the investee.

If the fair value is lower than the carrying amount, we will consider whether the loss is other than temporary. Factors considered when evaluating whether a loss is other than temporary include:

(i) the length of time and extent to which the fair value of the investee has been less than its carrying amount

(ii) the investee's financial condition and near term prospects, including recent operating losses or specific events that may negatively influence its future earning potential; and

(iii) our intent and ability to retain the investment for a period of time sufficient to allow for an anticipated recovery in fair value.

When we conclude the loss is other than temporary, we would record an impairment against the investment's carrying amount and report the impairment loss in our consolidated statement of operations and comprehensive loss. As at December 31, 2025, we concluded that there was no impairment loss in our investment in Cespira.

33

Property, plant, & equipment ("PP&E") and Right-of-use assets
We consider whether or not there has been an impairment in our long-lived assets, such as plant and equipment, furniture and leasehold improvements and right-of-use assets, whenever events or changes in circumstances indicate that the carrying value of the assets may not be recoverable. If such assets are not recoverable, we are required to write down the assets to fair value. When quoted market values are not available, we use the expected future cash flows discounted at a rate commensurate with the risks associated with the recovery of the asset as an estimate of fair value to determine whether or not a write down is required.

Impairment of PP&E
We have significant long-lived assets related to our High-Pressure Controls segment in our new Canada and China manufacturing facilities. In the current year, we had hydrogen development program cancellation by a customer that resulted in certain dedicated PP&E impacted by the cancellation. As a result, we recognized an impairment loss of $0.5 million in the year. Although there is a general slowdown in the hydrogen infrastructure development, leading to a slower adoption of automotive and industrial applications powered by hydrogen, we continue to see a demand for our products and ongoing activity in research and development with our global OEM partners. The long-lived assets in our High-Pressure Controls segment are fuel agnostic and not solely for hydrogen applications. As of December 31, 2025, we have concluded that there are no other impairment indicators.

B. Director Compensation
The compensation structure of the Board of Directors is designed to attract and retain exceptionally talented and experienced directors, leading to our long-term success. This requires our directors to be adequately and competitively compensated. The Board has determined that director compensation should be in line with comparable companies and
35

reflect the time, responsibilities of our directors as well as current trends in director compensation. The HRC Committee reviews these factors based on relevant market data and advice of our external compensation consultant when making recommendations on Director compensation to the Board.
Director Share Ownership Requirements
The Board encourages directors to obtain a meaningful share ownership interest in Westport. In 2020, the Board approved an increase in the number of shares required to be held by non-employee directors. Under the share ownership guidelines applicable to all non-employee directors, each director must hold at least five times their annual cash retainer in Common Shares or Units, to be acquired over a five-year period from their election to the Board.

Each of the non-employee directors complied with the guidelines regarding share ownership as of December 31, 2025, or is reasonably proceeding with compliance having regard to the applicable fifth anniversary of his or her initial election to the Board. Mr. Kotush was appointed to the Board on January 1, 2026. For further details on director share ownership, please review the individual director biographies in "Board Practices: Nominees for Election to the Board."
Director Compensation Schedule
Fixed annual retainers are used to compensate directors rather than a fee per meeting. The retainer is comprised of a combination of cash and equity compensation. Non-management directors are paid a base annualized cash board retainer and equity compensation in the form of DSUs and Committee Chairs are paid a base annualized cash committee chair retainer, all as reflected in the schedule below.

In 2023, the HRC Committee completed a further director compensation review with Hugessen Consulting ("Hugessen" or "Compensation Consultant") which resulted in the decision to change from Directors to being able to elect to take equity compensation in RSUs, DSUs or a combination, to only awards in DSUs for equity compensation. Compensation in the form of DSUs is at risk since DSUs can be redeemed only upon a director retiring from the board, and the redemption value of DSUs depends on the market value of our shares at that time.

In 2024, the HRC Committee completed a director compensation review with Hugessen, which resulted in the elimination of Committee Member retainers. At the June 13, 2024, Board Meeting, the Board approved that Directors also could elect to take all or a portion of their cash retainers in the form of DSUs. These adjustments were made to align with our strategic priority of reducing our cost structure, enhancing efficiency, and improving cash management.

No changes were made to chair or non-chair director compensation cash retainer or equity compensation levels in 2025.
Directors are also reimbursed for travel and other reasonable expenses incurred in connection with Board or committee meetings. Mr. Sceli does not receive compensation for his role as a director and is instead compensated solely as a member of management. The following table outlines the 2025 Director compensation approved on May 15, 2025.

B. Compensation of Executive Officers
Named Executive Officers

The following discussion relates to the compensation program for Westport's "CEO", the "CFO" and the next three most highly compensated executives or employees as at December 31, 2025, and two executives that transferred with the sale of the Light-Duty business unit (collectively "NEOs").

•Daniel Sceli, CEO
•Elizabeth Owens, CFO
•William Larkin, former CFO
•Lance Follett, Chief Legal Officer and Executive Vice President, Corporate Development
•Ashley Nuell, Vice President, Investor Relations
37

•Jim Mancuso, Vice President, High Pressure Controls and Systems
•Bart van Aerle, former Executive Vice President, Independent Aftermarket & Light Duty Original Equipment Manufacturing
•Frank Spinello, former Vice President, Financial Operations and Amministratore Delegato, Westport Fuel Systems Italia

Changes to the NEOs

Effective August 26, 2025, Mr. Larkin stepped down as CFO and resigned from all positions with the Company effective as of September 15, 2025.
On August 26, 2025, Ms. Owens was promoted and appointed CFO.

Effective July 29, 2025, Mr. Van Aerle and Mr. Spinello transferred with the disposition of the Light Duty segment.

Executive Compensation Philosophy
Our compensation philosophy is to pay for performance over the long-term, as well as on an annual basis. Our performance considerations include both financial and non-financial measures—including the way results are achieved—for the Company, line of business, and the individual. The "Compensation Governance" section below presents the range of performance and governance considerations the HRC Committee considers as inputs into compensation decisions. These factors are evaluated each year and have remained consistent over time as part of a balanced and disciplined approach to the compensation decision process. Within that framework, key company, and business segment performance considerations for 2025 and the "Individual performance highlights" are the key considerations for the performance for each of our NEOs. These considerations reinforce and promote fiscal discipline and responsible growth and maintain alignment with our executive compensation philosophy. Our executive compensation program provides a mix of salary, incentives, and benefits paid overtime to align executive officer and shareholder interests. Our HRC Committee is responsible for approving our compensation strategy and philosophy and the compensation programs applicable to our named executive officers.

Compensation Governance
The HRC Committee is responsible for administering our executive compensation program, which, among other things, includes:

•Determining the compensation for our executive officers, including base salary, short and long-term incentive opportunities, performance benchmarking and market analysis.
•Reviewing, approving and administering our executive compensation plans, including our equity plans.
•Establishing performance objectives under our short and long-term incentive plans.
•Determining the attainment of performance objectives and the resulting awards pursuant to our "STIP" and "LTIP".
•Evaluating CEO performance and the performance and capabilities of Executive Management, based on input from the CEO.
•Evaluating executive officer compensation practices to ensure they remain equitable and competitive.
•Reviewing succession planning for executive officer positions, including the CEO.
•Reviewing and approving the mandate and terms of the Compensation Consultant.
•Approving employee benefit plans.

To provide support and assistance to the governance and oversight of our compensation process, the HRC Committee originally retained Hugessen on September 26, 2019, as an independent compensation advisor to provide executive and director compensation consulting services. This engagement and the annual workplan are reviewed and approved annually by the HRC Committee. Hugessen participates in certain HRC Committee meetings where executive compensation matters are discussed. As part of its services, Hugessen provides the following services when required:

•reviews market data and participates in the design of executive compensation programs to help the HRC Committee evaluate the linkage between pay and performance, including the selection of peer group companies and market data analysis;
38

•informs the HRC Committee on market trends, as well as regulatory issues and developments and how they may impact the Company's executive compensation programs; and
•reviews and advises the HRC Committee regarding director compensation, including market trends, as well as regulatory issues and developments regarding director compensation.

The HRC committee seeks review and input from Hugessen as required, including with respect to proposals from management. Additionally, the HRC Committee and Hugessen will meet without management present to make final decisions or recommendations to the Board. This supports responsible oversight of executive compensation. Recommendations made by the HRC Committee are based on multiple sources including advice received from our Compensation Consultant.

Services provided by Hugessen in 2025 were related to executive and director compensation. No other services were performed by Hugessen and no other fees were paid in 2025. In 2025, alignment changes were made to the compensation plans, and the HRC Committee did not undertake a benchmarking exercise, resulting in lower fees in 2025. It is expected that the fees in 2026 will increase as the HRC Committee will review the Omnibus Plan's available pool and complete appropriate benchmarking reviews.

The table below summarizes the fees paid in relation to executive and director compensation consulting services for the past two financial years. Any additional consulting services required by the Compensation Consultant outside of those relating to executive compensation must be pre-approved by the HRC Committee before proceeding.

Westport maintains its commitment to building long-term shareholder value by using a balanced performance measurement framework aligned with our key performance metrics and ensuring adherence to general governance best practices. The
39

following table outlines some of the best practices the HRC Committee employs in implementing the compensation program:

What We DoWhat We Don't Do
•Provide a meaningful part of pay which is "at risk" and contingent upon corporate and individual performance
•Ensure the pay opportunity is capped
•Retain external experts who report directly to the HRC Committee
•Benchmark pay levels and mix to other organizations of comparable size in a similar industry and geographic area
•Review peer group on a regular basis for continued appropriateness
•Ensure the majority of executive long-term compensation vests based on performance
•Ensure the short-term incentive award criteria is well defined, aligned to business strategy and reflects pay for performance
•Mitigate risk by having Anti-Hedging and Clawback policies in place
•Include a “double trigger” in executive employment agreements so that severance payments are due upon a change of control only if employment is also effectively terminated
•Align executive interests with Shareholders’ by having equity ownership guidelines for directors and executive officers
•Provide Shareholders an opportunity to have their say on executive pay decisions through an annual advisory vote
•No offering or repricing of stock options
•No offering of tax gross ups
•No pledging of our Common Shares as collateral for a loan or holding our Common Shares in margin accounts
•No hedging or "short sales" of our shares
•No defined benefit retirement plan or supplemental executive retirement plan
•No excessive executive perquisites
•No issuance of severance above applicable common-law entitlements; instead, efforts are made to keep severance entitlements in line with industry best practice
Compensation Risk Management
Promoting appropriately incented behaviors is an essential part of the compensation setting process. The HRC Committee believes measured risk is necessary for continued growth and innovation, but that risks should be encouraged within parameters that are appropriate for the long-term health and sustainability of the business. Performance relative to incentive targets is regularly reviewed and the HRC Committee is updated periodically to effectively monitor performance and manage inherent risk.

The HRC Committee believes annual STIP bonus plans and LTIP awards granted to executive officers should tie to business performance goals, such as revenue, Adjusted EBIT, operating cash flow, operating metrics and strategic performance objectives and shareholder value creation. These metrics encourage an ownership mindset as these individuals strive to achieve overall business performance. Awards are subject to a maximum payout cap.

The HRC Committee works with independent external consultants to stress test each component, ensuring boundary conditions are reasonable and do not produce unexpected or unintended financial windfalls.

We have implemented a Clawback Policy to ensure that incentive compensation is paid based on accurate financial data. Executive Officers may be required to forfeit or pay back any excess bonus amounts, or equity-based compensation should the Company's financial statements be restated as a result of material non-compliance with any financial reporting requirements under applicable securities laws (other than a restatement due to a change in financial accounting rules).

We have also adopted an Anti-Hedging Policy, which prohibits officers, directors, and employees from engaging in hedging against future decreases in the market value of the securities of the Company through the purchase of financial instruments designed to hedge or offset such risk.

Additionally, Westport, as a foreign private issuer, is subject to certain U.S. legislation, including provisions of the Sarbanes-Oxley Act. The Sarbanes-Oxley Act provides that in the event an issuer is required to prepare an accounting restatement as a result of the material non-compliance of the issuer with any financial reporting requirement, the CEO and
40

the CFO of the issuer will be required to reimburse the issuer for certain elements of such executive's compensation. In Westport's case, the elements include annual bonus and PSUs issued under our omnibus incentive plan (the "Omnibus Plan"). Westport abides by these laws.
Share Ownership Requirements
Non-employee directors and executive officers are required to meet share ownership guidelines and hold equity in the Company to align their interests with those of our shareholders:
•Our non-employee directors are required to hold a minimum of five times their annual cash retainer in Common Shares or Units (as subsequently defined).
•Non-employee directors have five years from the date the director is elected to the Board to accumulate the minimum threshold required under the share ownership guidelines.
•Each of our Executive Officers, except for the CEO, is required to hold a minimum of one time of their annual base salary in Common Shares or Units.
•The CEO is required to hold a minimum of three times their annual base salary in Common Shares or Units.
•Executive Officers (including the CEO) have five years from the date they are appointed as an executive officer to accumulate the minimum threshold required under the share ownership guidelines. For Executive Officers, the ownership threshold is based on the individual's annual base salary for the preceding financial year.

The value of the Common Shares or Units owned by each non-employee director and NEO for the purposes of achieving the share ownership guidelines is the greater of: (i) the acquisition cost of any Common Shares or the grant price of any Units; and (ii) the market value of the Common Shares at the time of the determination. The table below summarizes each NEO's holdings as of December 31, 2025.

Executive Compensation Discussion and Analysis
Our executive compensation program is designed to retain, attract, motivate, and reward our Executive Officers who advance our strategic, financial and operational objectives and thereby enhance shareholder value. The HRC Committee believes the executive compensation program's underlying philosophy and related policies maintain a robust pay for performance alignment, which factors in the median levels of both local market and peer compensation data to balance pay mix and level targets of its executives and employees.

Westport's compensation program is based on the following philosophy:

•Pay for performance - salary, bonus and equity awards are linked to both corporate performance and achievement of goals against an individual's area of responsibility.
•Long-term incentives - balance retention and performance-based equity compensation to be aligned with shareholder value creation.
•Competitive total compensation - factors in the median levels of both a defined comparator group of peers' compensation and local market data to balance pay mix and level targets for executives and employees across the geographies in which we operate.
Determination of Compensation

The HRC Committee establishes the compensation philosophy and evaluates the design and merits of executive compensation programs through comprehensive reviews to ensure the executive compensation and benefit programs align with shareholders' best interests, while considering any risks associated with our compensation policies and practices. The HRC Committee's recommendations factor in the competitiveness for talent and are reached primarily through benchmark analysis conducted by Hugessen, which assists in determining whether our executive compensation program is both reasonable in relation to competitive pay levels and appropriate in supporting business objectives that encourage a positive performance-based culture. Our current philosophy is to target pay at the median of the a pre-determined comparator group of companies (the "Comparator Group") recognizing that pay is often correlated with company size.

In the fall of 2023 Westport completed a comprehensive review of its Comparator Group against selection criteria which included revenue, global scope, EBITDA, Total Enterprise Value ("TEV"), market capitalization, business complexity, industry presence and geography. As a result, a new Comparator Group was adopted to ensure a more robust and relevant set of peer data would be used as the basis for compensation program reviews and overall compensation decision making going forward. The table below outlines the 20 companies which form the Comparator Group and includes 8 U.S., 7 European, 3 United Kingdom and 2 Canadian based companies:

Bulten AB (publ)Ideanomics, Inc.Somero Enterprises, Inc.
Ballar Dewhurst Group PlcLandi Renzo S.p.A.Strattec Security Corporation

Gencor Industries, Inc.Manitex International, Inc.Tornado Global Hydrovacs
Glaston Oyj AbpMincon Group plcTwin Disc, Incorporated
GreenPower Motor CompanyMpac Group plcXos, Inc.
hGears AGPWO AG

As the Company was going through a strategic transition in 2025 which resulted in changes in organizational size, global footprint, business complexity and market capitalization the HRC Committee felt it was appropriate to consult with Hugessen with respect to best practice in compensation decisions and alignment in the Company's situation.

For more information on the LTIP, please see "Elements of our Executive Compensation Program: Long-Term Incentive Plan."

Executive Compensation At Risk

A significant portion of executive pay is designed to be "at risk", meaning that it is not a guaranteed payment, and that payment varies with performance. To align with our pay for performance philosophy, a substantial percentage of the executives' total compensation is comprised of short-term and long-term incentives which link directly to corporate performance and / or relative total shareholder return ("TSR"). The following table shows the targeted mix of compensation components and demonstrates the proportion of "at risk" pay for the CEO, CFO and other NEOs employed at December 31, 2025 relative to their total compensation in 2025.

Base Salary

Base salary guidelines and salary adjustments for executive officers are designed to recognize market compensation trends, acknowledge competencies and skills of individuals, and match the expected market value of senior executives based on executive experience and qualifications. We typically target median base salary levels of our Comparator Group and factor in local market adjustments for base salary where applicable. Executive officer base salaries remain fixed throughout the year unless a promotion, change in responsibilities, or special circumstances occur.

Short-Term Incentives

43

The STIP is the primary method for motivating business and individual performance during the financial year and is intended to link pay and performance during the annual operating cycle by providing cash compensation if targeted results are achieved, up to a capped percentage amount of base salary.

The CEO's performance metrics are approved by the HRC Committee for each annual financial period. The corporate performance metrics for NEOs are set by the CEO and reviewed by the HRC Committee before being recommended to the Board of Directors. Payouts are made after the HRC Committee reviews and approves the calculations of performance against the goals for the year and only after the Audit Committee approves audited fiscal year financial statements.

Following the sale of the Company's Light-Duty Business segment in 2025, the HRC Committee determined that, during this period of strategic transformation, 30% of the STIP value should be tied to the financial target of adjusted EBIT. This approach aims to balance operational accountability with strategic flexibility. The adjusted EBIT metric maintains a clear line of sight for management decisions and outcomes on controllable operating performance. This metric provided a clear link to the Company's operational excellence focus and has been a consistent metric for prior STIP programs. Strategic initiatives focused on the Company's business model were set at 60% of the value of the bonus. Each of the following strategic initiatives included defined measurable performance criteria relating to financial metrics, project milestones, and customer and stakeholder engagement:

•Transfer of the retained High-Pressure Control (Hydrogen) manufacturing from Italy to Canada and China
•North American natural gas heavy-duty market entry path validation
•Organizational size and cost realignment
•Strategic partners and capital attainment

The balance, weighted at 10%, was linked to individual performance

See "2025 Executive Compensation: Short-Term Incentives" for details on results.

Long-Term Incentives

The long-term incentives ("LTIs") are established to support retention, facilitate executive stock ownership and reward for multi-year shareholder value creation. LTIs comprise a significant "at-risk" element of total compensation for Executive Management. The design and magnitude of long-term incentives are guided by several factors, including:
•the design must be aligned with shareholder value creation
•the design should be supportive of the Company's business goals and strategic plan
•the design must be retentive

In prior years, the HRC Committee analyzed market data, Comparator Group data and assessed recommendations from its Compensation Consultant along with information provided by management in determining LTI program design, metrics and targets. The HRC Committee believes that a three-year ratable vesting for restrictive awards such RSUs and a three-year cliff vesting and performance period for PSUs are each an appropriate length of time to support retention, motivate executive performance, and align with shareholder interests. Three-year vesting is also consistent with common market practice and taxation principles. Performance awards only vest and entitle the holder to Common Shares or a cash payout if minimum thresholds are achieved. If the performance metrics are not attained in the three-year performance period, the PSU award will expire and be returned to the pool of awards available for future grants under the Omnibus Plan. The PSU awards have previously used a combination of relative Total Shareholder Return ("rTSR") and Share Price Appreciation ("SPA") metrics. The performance of PSUs was measured against Comparator Groups comprised of selected North American based companies on a U.S. based stock exchange.

The following table summarizes the LTI factors and metrics that were used in prior years to provide grants under the LTIs:

CEO recommendations on LTIs are limited to Executive Management and key employees (other than himself). The HRC Committee then approves the grants of LTI awards for the NEOs, other executives, and other key employees. CEO LTI awards are determined by the HRC Committee, with consultation from the Board Chair.

In 2010, Shareholders approved our current Omnibus Plan. The Omnibus Plan was re-approved by Shareholders for an extended term in 2020 and is designed to provide flexibility to the Board of Directors to issue equity-based incentives to align compensation with shareholder interests over the long-term and offer the ability to retain and attract the best talent globally.

Although the Omnibus Plan allows for the use of Options, virtually all grants made over the life of the Omnibus Plan have taken the form of Units which will ultimately convert into Common Shares of the Company following vesting. On a limited basis Restricted Phantom Shares ("RPSs") have been granted where the recipient receives cash compensation instead of Common Shares of the Company on vesting and to address differing taxation requirements across the various jurisdictions in which we operate.

Long-Term Incentive Plan (“LTIP”)

In 2019 the HRC Committee approved the adoption of an LTIP that consists of a combination of: (i) time restricted awards in the form of RSUs or RPSs that ratably vest over three years; and (ii) performance-based awards in the form of PSUs that are linked to shareholder value creation metrics, subject to a performance-based payout scale and fully at-risk with the potential for zero payout. RPSs are intended to be awarded to non-executive employees in operating regions outside North America to simplify the conversion process.

In 2023, the HRC Committee adjusted the performance metric to a single metric of rTRS for the PSU awards granted to the management team ensuring the majority of the awards are based on pay-for-performance metrics and aligned with shareholder value creation. In 2023, the HRC Committee introduced restrictive cash-based awards at the employee level outside of North America, replacing the RSU, RPS and PSU awards.

In 2024, the HRC Committee did not award performance-based awards in the form of PSUs as the Company was in a transition phase with respect to the formation of the HPDI joint venture new CEO. The LTIP awards for 2024 consisted of time restricted awards in the form of RSUs that ratably vest over three years as retention of Executive Management through this transition period was viewed to be imperative.

In 2025, the Company initiated a strategic transition to reposition the business for sustainable value creation. In this context, the HRC Committee determined the 2025 LTI awards would consist of only PSUs and selected the SPA metric to measure absolute shareholder value creation, reflecting the market's assessment of the effectiveness of the Company's strategy, execution, and capital allocation decisions. Participants realize value only if the Company's share price increases over the performance period.

The HRC Committee determined that rTSR is less appropriate during the strategic transition due to the evolving nature of the Company’s business model and a stable and comparable peer group should be determined in 2026. A SPA metric avoids potential distortion arising from peer group volatility and ensures the incentive outcomes are aligned with the actual shareholder experience.

As such, 100% of the LTIP awards in 2025 were performance based.

45

On August 11, 2025, the HRC Committee approved the following LTIP, with the performance period to end December 31, 2027 ("PP End Date"). Performance awards only payout if minimum thresholds are achieved and are capped to ensure positive shareholder value transfer is created with the award. If the performance metrics are not attained in the performance period the PSU award will be returned to the Omnibus Pool for future award.

These PSU awards will vest and are dependent on:

•Payout criteria 1 – if payout criteria 2 is not achieved, the number of awards which vest in accordance with payout criteria 1 shall be determined in the manner indicated in the table below are ultimately vested and settled.
•Payout criteria 2 - 100% of the PSUs will vest and settle if the trailing 20-day volume weighted average share price of Westport Fuel Systems shares on the NASDAQ is at or above $7.62 USD at any point before the PP End Date.

Other Benefits

In addition to the executive compensation program described above, our executives participate in Company-wide employee benefit programs within their region of employment, such as short-term disability income benefit, health and dental care including dependent coverage, employee life insurance, dependent life insurance, accidental death and dismemberment insurance and the matching of regional long-term savings plans. These programs vary by region of operation and are offered to all employees employed within the region of operation. The Company offers an additional voluntary executive health and wellness benefit to our executives on a cost-sharing basis. The Company does not offer a defined benefit pension plan to executives. In addition, Westport offers only limited benefits and perquisites, and current offerings to our NEOs are consistent with market practice.

Payments Upon Termination

In the event of termination of employment without cause, such as may be the case in the event of a change of control, certain Westport NEOs are entitled to an amount of compensation as outlined in the "Employment Agreements - Termination and Change in Control" section of this Form 20-F.

Short-Term Incentives
CORPORATE PERFORMANCE
Each NEO's STIP objectives included a financial metric related to achieving better than budgeted Adjusted EBIT (weight of 30%) and as well the strategic initiatives (weight 60%) focused on the Company's business model changes. The remaining weighing of 10% related to individual performance as assessed and recommended by the CEO to the HRC Committee.

The financial metric of Adjusted EBIT was based on the Board approved budget and was set with the following pay out levels:
•a minimum payout (0.5x) threshold of achieving 10% better than budget;
•a target payout (1.0x) of achieving 20% better than budget; and
•a maximum payout (1.5x) of achieving 35% better than budget.

The minimum payout threshold was not met, thus the HRC Committee approved 0% pay out of a possible 30%.

Within each of the strategic initiatives, there is a combination of defined financial metrics, project-based milestones, and stakeholder engagement metrics. The Company was able to advance the progression of the strategic initiatives in 2025, including corporate restructuring and relocation of our High Pressure Controls manufacturing plant and establishing the foundations for entry into the North American natural gas, heavy-duty market. The HRC Committee reviewed progress and achievement of each of the initiative's metrics with the CEO and approved a 15% payout out of a possible 60%.

The Strategic Initiative are defined above in the “Elements of Our 2025 Executive Compensation Framework – Short Term Incentives” section.

Individual performance was weighed at 10%, with a payout range of 0x to 1.5x. The HRC Committee approved payouts ranging from 10-15%.

Payout amounts for each NEO are listed in full in the "Executive Compensation Figures & Tables" section.
For more information on the financial performance during 2025, see the Company's MD&A and financial statements, filed on SEDAR+ at www.sedarplus.ca and available on our website.
CEO SHORT-TERM INCENTIVE ACHIEVEMENT
As per the CEO's employment agreement, the short-term incentive ("STI") component of the CEO's compensation has a target of 100% of base salary, with potential payout between 0% and 150% of base salary depending on performance against predefined corporate and individual performance targets. The table below summarizes the original metrics and weighting for the CEO and the actual achievement in 2025. The HRC Committee has approved a quantitative performance rating of 0% out of a possible 30% weighting for the financial measure of the STIP for 2025. The key qualitative targets for the CEO’s 2025 STIP were reviewed by the Board and the Board awarded the CEO a performance rating of 15% for the strategic initiatives. The evaluation of the qualitative metrics and individual performance is based on Board discretion at the recommendation of the HRC Committee after assessing the defined milestone achievements of initiatives related operational effectiveness, organizational transformation and external stakeholder engagement.

This resulted in an overall CEO performance score of 30% for a total STIP payout of $143,835 for 2025.

Targeted bonuses for the other NEOs, range from 35% to 50% of base salary, with a potential payout between 0% and 150% of target bonus depending on performance against predefined corporate and individual performance targets. Depending on the NEO’s area of responsibility, metrics were established and weighted in alignment with the STI design principles noted above.

Factoring in the financial and strategic metric performance outcomes and individual performance (target weighting of 10%) the HRC Committee approved STIP performance objective ratings ranging from 25% to 30% for the NEOs. NEO STIP participation rates as a percentage of base salary are 50% for Ms. Owens and Mr. Follett and 35% for Ms. Nuell and Mr. Mancuso. The approved payout values ranged from 8.75% to 15% of base salary. These payouts are recorded in the Compensation Summary Table below.

The consolidated financial performance metrics associated with the NEO's STI were based on the 2025 Annual Operating Plans approved by the Board of Directors.
Ms. Owens payout value was pro-rated for the year, factoring in her prior position prior to being appointed CFO.

With the disposition of the Light Duty Business Unit, Mr. van Aerle and Mr. Spinello were not participants of the STIP in 2025. They were eligible to receive a transaction bonus with the closing of the sale of the Light Duty Business Unit. The transaction bonus was intended to address execution and continuity risks associated with a complex carve-out and sale process, including operational separation, regulatory approvals, customer transition and preservation of transaction value through closing.

Payout amounts for each NEO are listed in full in the "Executive Compensation Figures & Tables" section.

2023-2025 Long-Term Incentive Awards
Under the LTIP, in March of 2023 the Company awarded RSUs and PSUs for the three-year retention and performance period for the period of 2023 – 2025. The PSUs were set to become available after December 31, 2025, contingent upon total shareholder return targets achieved over the applicable three-year period, calculated using the weighted volume average share price of Westport shares on the NASDAQ over the preceding 20 days.

Based on the measurement of the required vesting conditions, 0% of the PSUs awarded for the 2023-2025 period met the required vesting conditions to vest and therefore all PSU awards for this period expired and 37,010 units were returned to the equity reserve under the Omnibus Plan.

Following the disposition of the Light Duty Business Unit, LTI participants who transferred with the transaction had their RSU and PSU awards vested at closing and settled in cash, rather than in shares in accordance with the terms of the awards. These awards were returned to the Omnibus Equity Plan pool. The HRC Committee assessed the 2023-2025 PSU awards applicable performance vesting conditions at the time of the Light Duty disposition announcement and determined that 95% of the PSUs awarded would have met the required vesting conditions. A total of 17,721 units vested and were returned to the equity reserve under the Omnibus Plan, with a total cash settlement of $34,175. The HRC Committee
48

approved the accelerated vesting of RSUs at closing and were settled in cash rather than receiving shares in accordance with the terms of the awards. A total of 3,319 units were vested and returned to the equity reserve under the Omnibus Plan, with an aggregate cash settlement value of $6,738.

2024 Long-Term Incentive Awards

Under the LTIP, the 2024 LTI awards consisted of time-restricted awards in the form of RSUs that ratably vest over three years, as retention of executive management through this transition period was viewed to be imperative. One-third of these awards vested in December 2025, with the final third to vest in December 2026.

Following the disposition of the Light-Duty Business segment, the HRC Committee approved the accelerated vesting of RSUs for participants who transferred with the transaction. These awards vested at closing and were settled in cash rather than receiving shares in accordance with the terms of the awards. A total of 2,590 units vested, with an aggregate cash settlement value of $5,335, and were returned to the equity reserve under the Omnibus Plan.
Payout amounts, if any, for the prior year LTIP in 2025 for each NEO are listed in full in the table "Value Vested or Earned During the Year" in the "Other Plan Awards" section below.

2025 Long-Term Incentive Awards

Under the LTIP, in August of 2025 the Company awarded 290,540 PSUs for the performance period for the period of 2025-2027. Payout amounts for each NEO are listed in full in the "Executive Compensation Figures & Tables" section.

Share Performance Graph
The Common Shares have been listed and posted for trading on the TSX under the trading symbol "WPRT" since November 10, 2016 (and under the trading symbol "WPT" prior hereto), and the NASDAQ under the trading symbol "WPRT" since August 18, 2008. The following graph and table compare cumulative total shareholder return from an investment of C$100 in Common Shares of the Company made on December 31, 2020, with the cumulative total return of the S&P/TSX Composite Total Return Index over the same period, assuming reinvestment of dividends. Westport’s executive compensation is structured in a manner that is intended to align with shareholder value creation. Westport’s STI has paid out below target over this period and the LTIP PSU awards have not paid out over the past several performance cycles, consistent with the shareholder experience.

Executive Compensation Figures and Tables
Financial Year 2025 Summary Compensation Table
The following tables and notes thereto set out information concerning the compensation paid, payable, awarded, granted, given or otherwise provided, directly or indirectly, to our NEOs in financial years 2023, 2024 and 2025. The table reflects the CFO transition, the NEOs at December 31, 2025, and the NEOs that transferred with the disposition of the Light-Duty business. The Company does not have a pension plan; therefore, the pension contribution for the NEOs is nil.

The aggregate cash compensation (salary and non-equity incentive plan) earned by the NEOs remaining at December 31, 2025 during the financial year ended December 31, 2025, was $1,541,668 and the total compensation$2,305,048. Based on the 2025 STIP results, and the Share Unit awards received under the LTIP during fiscal year 2025, the sum of their actual fixed compensation was $1,287,988 or 56% of total compensation and actual at-risk pay was $979,390 or 42% of total compensation.

Notes:
1.Annual base salaries for the current NEOs as of December 31, 2025, were C$670,000, C$325,000, C$370,000, C$250,000 and C$250,000 for Mr. Sceli, Ms. Owens, Mr. Follett, Ms. Nuell and Mr. Mancuso respectively, and €225,000, €170,000, for Mr. van Aerle and Mr. Spinello respectively. The table above translates the Canadian and Euro dollar salaries into US dollars at the average exchange rate during the year.
2.The values of the RSUs and PSUs are determined by multiplying the number of RSUs and PSUs awarded by the NASDAQ exchange closing price of the Common Shares on the date of the award. These RSUs and PSUs typically vest over three years and the PSUs vest based on achieving performance criteria within a three-year performance period. The actual compensation earned by the NEO may ultimately be more or less than the amount indicated in this table based on whether the vesting criteria associated with such RSUs and PSUs are ultimately achieved. Historically, less than 100% of the issued share based awards have been vested.
3.This represents Westport short-term incentive awards. The amounts were accrued in the year reported but paid to the NEOs in the subsequent year. For details on non-equity incentive plan values paid during the fiscal year, see table titled "NEO Incentive Plan Awards: Value Vested/Earned".
4.The column entitled "All Other Compensation" includes Westport's contributions to each NEO's long-term savings plan, where applicable. These are voluntary participation programs where the employer matches employee contributions up to a maximum of 5% of base salary per pay period. In addition, it includes additional bonuses and allowances (such as housing and vehicle).
5.Ms. Owens was appointed CFO on August 26, 2025. STI awards were pro-rated for 2025 based on her time as Vice President, Finance and CFO.
6.The Company entered into a mutual separation agreement dated August 26, 2025 in connection with Mr. Larkin stepping down as the Company's Chief Financial Officer. Pursuant to the agreement Mr. Larkin was entitled to be paid $530,624 ($400,000 lump sum and $106,250 prorated 2025 STIP entitlement as per his employment agreement). Mr. Larkin was also paid $101,126 in accrued vacation pay.
7.Mr. Larkin and Mr. Follett were paid an additional $25,000 and $16,345 respectively in salary in 2024 and $50,000 and $33,588 respectively in salary in 2023 in relation to their additional duties during the CEO transition period. Additionally, Mr. Larkin and Mr. Follett were awarded $150,000, and $100,000 PSUs respectively in 2023 in relation to their additional duties during the CEO transition period. Mr. Larkin and Mr. Follett were paid $75,000 and $49,648 respectively as a one-time bonus in 2024 respectively in relation to the close of Cespira HPDI Joint Venture.
8.The compensation reported for Mr. van Aerle in fiscal 2025 includes a one-time, non-recurring transaction bonus of $252,563 in connection with the sale (disposition) of the Company's Light-Duty Business Unit. The transaction bonus was intended to address execution and continuity risks associated with a complex carve-out and sake process, including operational separation, regulatory approvals, customer transition and preservation of transaction value through closing. Following the disposition, Mr. van Aerle's transferred with with the disposed business unit transferred with the transaction. Mr. van Aerle did not participate in the Company's 2025 STIP and was not awarded LTI equity in fiscal 2025.
9.The compensation reported for Mr. Spinello in fiscal 2025 includes a one-time, non-recurring transaction bonus of $190,825 in connection with the sale (disposition) of the Company's Light-Duty Business Unit, which caused Mr. Spinello to qualify as an NEO for fiscal 2025 disclosure purposes. The transaction bonus was intended to address execution and continuity risks associated with a complex carve-out and sake process, including operational separation, regulatory approvals, customer transition and preservation of transaction value through closing. Following the disposition, Mr. Spinello transferred with the disposed business unit transferred with the transaction. Mr. Spinello did not participate in the Company's 2025 STIP and was not awarded LTI equity in fiscal 2025.

Other Plan Awards
During the year ended December 31, 2025, DSUs, were granted for Board of Director compensation (see section "Director Compensation") and PSUs were issued to certain employees of the Company (including grants made to NEOs) for LTIP purposes. Excluding director compensation, 290,540 PSUs were issued during the year ended December 31, 2025. The value of the PSUs, are based on the fair market value on the date of the grant.

2.This is a notional amount that is calculated by multiplying the number of Units by the closing price of the Common Shares underlying the Units on the NASDAQ as of December 31, 205 ($1.57). Such amounts may not represent the actual value of the Units that ultimately vest, as the value of the Common Shares underlying the Units may be of greater or lesser value on vesting.

Employment Agreements: Termination and Change in Control
The CEO and CFO have signed employment agreements which include standard industry terms and conditions, such as intellectual property and confidentiality provisions. Pursuant to the terms of these agreements, in the event of termination of employment by Westport without cause, the entitlements for the CEO and CFO are outlined below. The other NEOs do not have any termination provisions in their employment agreements as statutory requirements, and common law would apply.

Mr. Sceli entered into an employment agreement on January 16, 2024. Under the terms of this agreement, in case of termination without cause Mr. Sceli is entitled to 1.25 times the aggregate sum of base salary plus target annual performance incentive, plus an additional one twelfth of the aggregate sum of base salary plus target annual performance incentive for every year of company service completed.

Ms. Owens entered into an employment agreement on August 23, 2025. Under the terms of this agreement, in case of a termination without cause Ms. Owens is entitled to a minimum 12 months’ of base salary plus one month base salary per year of service in the position of CFO, to a maximum of 18 months, plus a partial incentive bonus calculated on a pro rata basis for months worked within the fiscal year in which termination occurs plus, benefits coverage per the length of service to a maximum of 18 months.

Mr. Follett, Ms. Nuell, and Mr. Mancuso do not have any termination provisions within their employment agreements.

In the event of termination of any eligible recipient's employment with Westport without cause, all PSUs granted under the Omnibus Plan for which the measurement period has been completed would immediately vest with pay out in accordance with the resulting outcome of the award assessment of the grant and pursuant to the terms of the Omnibus Plan.

None of the NEOs have specific change in control provisions in their agreements, however they are covered under Westport’s Change in Control Policy (described below).

Westport has a change in control policy ("Change in Control Policy") that is intended to provide eligible executives of the Company with reasonable continuing financial security in their employment and position with the Company, without distraction from uncertainties or risks regarding their employment created by the possibility of a change in control of the Company. The Change in Control Policy applies to all permanent full-time officers, executive vice presidents, and senior vice presidents of the Company and certain affiliated entities as well as to certain other officers or executives who are designated by the CEO and ratified by the HRC Committee and entitles such participants to certain payments and benefits in the event the participant's employment is terminated as a result of a "Qualifying Termination" relating to a change of control, as defined in the policy. "Qualifying Termination" for this purpose is defined in the policy to mean either: (a) receipt by a participant of notice of termination of the participant's employment without cause (regardless of the effective date of such termination); or (b) the resignation of the participant's employment as a result of constructive dismissal, in each case during the period commencing on the change in control and ending on the date which is eighteen (18) months after the change in control. The Change in Control Policy generally provides that, in the event of a Qualifying Termination, the executive will be entitled to a cash payment ranging in an amount equal to either one and half (1.5) or two (2) times the aggregate sum of: (a) that executive's annual base salary plus the executive's target annual bonus amount; and (b) an amount equal to the annualized cost of the Company-sponsored medical, dental, vision insurance and executive medical and health care benefits in effect for the executive as at the termination date at a cost equal to either 150% or 200% of the Company's premium rate for such benefits, together with any accrued but unpaid salary as at the termination date. Pursuant to the Change in Control Policy, all unvested Option or RSU awards held by the terminated executive will also be deemed to be vested as at the date of the Qualifying Termination. Any PSU awards or any other award subject to any performance targets shall be reviewed the HRC Committee, which shall make a good faith determination as to whether or not the performance target has been achieved, the level at which such performance target has been achieved and the payout amount.
To the extent that an executive is entitled to benefits under both the Change in Control Policy and the terms of their existing employment agreement, such executive may elect to receive payments and/or benefits under such employment agreement in lieu of the payments or benefits so provided by the Change in Control Policy.

The following tables set forth, for each NEO employed at December 31, 2025, the amount such person would have been contractually entitled to receive on the termination of their employment without cause on December 31, 2025, and the amount such person would have been contractually entitled to receive if a change in control triggered the termination event on December 31, 2025, as per such person's employment agreement or Westport's Change in Control Policy.

We have a specific policy for our non-management directors of compensating such directors primarily with an annual retainer payment and equity-based compensation. See information under the heading "Director Compensation." Additionally, non-employee directors are required to meet share ownership guidelines and hold equity in the Company of a minimum five times their annual cash retainer in Common Shares or Units, to be acquired over a five-year period.(3) For further information see "Section 2: Share Ownership Requirements” of this Circular.
Notes:
1.The number of Common Shares and Units beneficially owned or controlled are provided as of April 23, 2026. The information as to these numbers, not being within the knowledge of Westport, has been furnished by the respective nominees. The number of Common Shares held by directors varies in shareholding positions primarily due to purchase price or grant amounts at varying times and share prices.
2.Certain of such Units are subject to a time-based or performance-based restriction.
3.In April 2020, the Board approved a change to the share ownership requirements for non-employee directors, increasing it to five times their annual cash retainer from the prior requirement of three. As a result, the expected acquisition period has been reset to five years for all non-employee directors. The value of the Common Shares or Units owned by each non-employee director for the purposes of achieving the share ownership guidelines is the greater of: (i) the acquisition cost of any Common Shares and the grant price of any Units; and (ii) the market value of the Common Shares at the time of the determination.

Structure and Composition of the Board and Election of Directors
The NCG Committee annually reviews the composition of the Board of Directors with consideration of our business strategy, all relevant facts and circumstances, individual director contributions, tenure, risk of over boarding and potential candidates for election as directors. The NCG Committee also has the responsibility to determine the optimum mix of business skills, experience, and diversity of the members of the Board of Directors to effectively fulfill its mission.

The NCG Committee then recommends to the Board a slate of directors for election by Shareholders that brings a diversity of background and industry or related expertise and experience to the Board. Directors are individually nominated and elected annually at Westport’s Annual General Meeting of Shareholders. There are no term limits for directors since the directors are subject to an election by Shareholders each year. If a nominated director fails to achieve a majority of votes for their appointment in an uncontested election, that nominated director is required to submit his or her resignation to the Board Chair in accordance with Westport’s Majority Voting Policy.
62

Board Leadership
The Board Chair sits at the intersection between the Board of Directors and Executive Management and, although the Board Chair is also a director and shares all the duties and responsibilities of any director, the Board Chair has several unique duties and responsibilities that include:
•presiding at all meetings of the Board of Directors and at Annual General Meetings of Shareholders, or delegate a substitute chair if necessary
•engaging with the chair of each committee to build strong and effective committees and, together with the NCG Committee, develops and oversees an effective annual performance review process to improve the performance of Board members and their committees
•leading special projects or taking on special assignments from the Board of Directors
•ensuring the Board of Directors operates independently from management and, for example, ensuring in camera sessions of the Board, excluding any directors who are also officers or employees, will be held at each meeting of the Board of Directors
The Board Chair is elected annually by the independent directors following the Annual General Meeting of Shareholders.
Board Independence and Effectiveness
Our business is conducted by Executive Management under the oversight of the Board of Directors. We believe an effective Board of Directors has a high degree of independence from management and, while a working culture of trust and collaboration must exist with Executive Management for us to succeed, the Board of Directors must exercise its duties and responsibilities in accordance with its own best judgment and its own views of the long-term interests of the organization and its Shareholders. The Board of Directors have adopted the following organizational principles:
•The Board of Directors must have a majority of independent directors. All directors except Mr. Sceli, who is our CEO, are considered independent within the meaning of National Instrument 58-101 - Corporate Governance Disclosure ("NI 58-101") and the listing rules of the NASDAQ and the TSX;
•The Chair of the Board of Directors, Mr. Gugliemin, is considered independent within the meaning of NI 58-101 and the listing rules of the NASDAQ and the TSX;
•During 2025, the Board of Directors maintained three standing committees (“Standing Committees”) and delegated specific responsibilities to each Committee. Each Committee operates under a charter and has a chair (“Committee Chair”) responsible for leadership and overall operation of the Committee. The Standing Committees are the Audit Committee, the HRC Committee, and the NCG Committee.
•The Audit Chair, the NCG Chair and the HRC Chair positions are held by independent directors, and all members of these Standing Committees are independent directors.
•The Board frequently reviews the need for new committees and may establish new committees or disband current committees at its discretion according to evolving circumstances, legal and regulatory requirements, as well as best corporate governance practices;
•The Board may form special committees and delegate specific responsibilities to address extraordinary matters;
•At every Board and committee meeting, time is set aside if needed for in camera discussion excluding any directors who are also officers or employees; and
•Where appropriate, executive sessions of only independent directors are held, with these sessions being overseen by the Board Chair.

Certain functions shall be the exclusive responsibility of independent directors, consulting closely with the Board Chair and CEO, who will then bring recommendations to the full Board of Directors for approval. These functions include:

•revising the Board of Director charter from time to time
•developing a position description for the Board Chair, the Chairs of each Committee, and the directors
•developing a position description for the CEO, as well as indicators to measure the CEO's performance

The Board, as well as each Standing Committee, may, in its discretion, and in consultation with the Board Chair, retain the services of independent outside professional advisors (financial, legal, compensation, other), at the expense of the Company, for the purpose of advising the Board or a Standing Committee in the execution of its responsibilities and duties.

Board of Directors Skills Matrix
Directors must have an appropriate mix of skills, knowledge and experience in business and an understanding of the industry and the geographical areas in which we operate. We maintain a critical skills matrix which identifies areas which are necessary for the Board to carry out its mandate effectively – now and in the future. The NCG Committee reviews the matrix annually to confirm it continues to reflect the most relevant skills, experience, and competencies. The skills matrix is also used in determining the appropriate mix of directors on each of the Standing Committees. Together with the Chair of the Board of Directors, the NCG Committee determines the expected skill set of new candidates by considering existing Board strengths and the needs of the organization. The following table identifies the skills and experience of our directors as ranked on a scale of one to three by each nominated director and defined below.

Diversity
The Board recognizes that diversity (including gender, as well as members of minority groups, geography, skills, competency and age) enriches the discussion, debate and facilitates a broader exchange of perspectives, which in turn, helps enable innovation, enhance balanced decision making, and improve business performance leading to greater organizational strength. Westport upholds its commitment to diversity through its diversity policy (the "Diversity Policy"), which sets out our commitment to actively considering candidates from diverse backgrounds based on merit, with a focus on gender diversity. For more information, please view the Diversity Policy here: investors.westport.com/governance/governance-documents/.  

The Board makes director nominee decisions based on merit and remains committed to selecting the best person to fulfil these roles. We recognize that diversity (including gender, as well as members of minority groups, geography, skills, competency and age) at both the Board and within all levels of management is important to provide a wide range of perspectives, experience and expertise required in building an effective team. We believe that diverse views enrich the discussion and debate and facilitate a broader exchange of perspectives, which in turn, helps enable innovation, enhance balanced decision making, and improve business performance leading to greater organizational strength.

Our Board is committed to upholding a gender balanced board as turnover occurs and consistent with this commitment, the Board has adopted a target of having women represent at least 30% of our Board. This commitment is reflected in both the Charter and in the Diversity Policy. We have met or exceeded this target at our annual meetings since 2020 and at our 2026 Annual General and Special Meeting, 33% of the nominees for our Board are women, with one of the three Standing Committees chairs in 2025 being a woman. Our current director nominees represent a well-rounded diversity of skills, knowledge, experience, and perspectives. All our nominees are seasoned leaders.

While the Company has not set a specific gender target for executive officers, 33% of our executive officers and senior management team are women: Chief Financial Officer and Vice President of Investor Relations. Given the size of the organization, the transition period, and small size of the executive team, the Company believes that implementing targets would not be appropriate.

The Company is committed to taking active measures to ensure candidate pools are diverse when assessing potential new executive officer candidates. Additionally, when using search firms to find executive officer candidates, the Company directs them to prioritize diversity, especially by including women candidates.

Orientation & Continuing Education
Robust onboarding for new directors is critical, as well as ongoing comprehensive education and training for all Board members on key matters and to foster board effectiveness. In addition, all Board members are encouraged to participate in relevant external director education opportunities. The Board recognizes: (1) the importance of fostering an atmosphere of continuous enhancement, long-term value creation, and strengthening shareholder confidence; and (2) that institutional investors and regulators expect directors at public companies to continually enhance their skills and remain up to date of company and industry matters.

Director onboarding involves a combination of written materials, oral presentations, meetings with the Board and management and site visits where possible. Among the topics covered during onboarding are company purpose, history, strategy, financial condition, risks, safety and soundness, ethics, core values, and corporate governance. To help new directors learn more about our business and their oversight roles within the organization, the onboarding process includes meetings with business segments, control and support groups, and visits to facilities as appropriate. This allows directors to
66

better step into their oversight roles and begin making meaningful contributions to the Board more quickly. In-house educational sessions facilitated by management are provided to all directors throughout the year with a focus on topics specific to our business and industry. All new directors must participate in the director orientation program which commences promptly after the appointment of a new director. In addition, the Board of Directors periodically receives advice from outside legal counsel and its auditors regarding changes in the regulations applicable to the organization.

Directors also participate in continuous learning activities as part of Continuing Education initiatives overseen by the NCG Committee. Continuing education covers a range of current topics including best practices in corporate governance, latest business and product information, cybersecurity, artificial intelligence and data privacy matters, and sustainability matters. Sessions are designed to maximize the knowledge and effectiveness of directors throughout their tenure and offer the opportunity to discuss in detail the changing risk environment, impacts on overall business strategy and achievement of our mission. During 2025, the directors attended an education session on AI.

Meetings of the Board of Directors
Our Board of Directors meets as needed during the year and a quorum for Board meetings requires a majority of its members to be in attendance. At every meeting, time is set aside for independent directors to meet without management present to discuss any procedural or substantive issues. The Audit Committee charter requires the committee to meet at least four times per calendar year in conjunction with the review and approval of annual and quarterly financial statements, management discussion, and analysis ("MD&A") and related filing. In 2025 the Audit Committee met 6 times. The HRC Committee and NCG Committee charters require each committee to meet at least twice annually. In 2025, the HRC committee met 7 times, and the NCG committee met 5 times. Detailed 2025 attendance by current directors is summarized in each director biography found in "Board Practices: Nominees for Election to the Board."

The NCG Committee reviews the number of boards on which our directors serve to ensure directorships align
67

The holders of our Common Shares are entitled to one vote per Common Share at meetings of shareholders, to receive such dividends as declared by the Board, and to receive Westport Fuel Systems' remaining property and assets upon dissolution
70

or winding-up. The Common Shares are not subject to any future call or assessment, and there is no exchange, pre-emptive, conversion, redemption or retraction rights attached to the Common Shares. The Board is elected annually at each annual general meeting of shareholders.

Under the Business Corporations Act (Alberta) we are permitted to conduct any lawful business that we are not restricted from conducting by our Articles. Our Articles do not restrict the business we may conduct.
Under the Business Corporations Act (Alberta), a director may vote on a proposal, arrangement or contract in which he or she is interested, if the contract is:

To the extent permitted by the Business Corporations Act (Alberta), the Board may from time to time delegate to a committee of directors, or to one or more of the directors and officers of the Corporation, all or any of the powers conferred to the Board to such extent and in such manner as the Board from time to time determines.

There is no specification in Westport's Articles or By-laws that indicate an age limit regarding retirement or non-retirement of directors.

The Articles, authorize the directors, between annual general meetings, to appoint one or more additional directors of Westport to serve until the next annual general meeting, provided that the number of additional directors does not exceed one-third of the number of directors who held office at the expiration of the last annual general meeting of Westport.
In order to amend the Articles to change the rights of holders of shares, a special resolution of Westport and of each class or series of shares affected by that change is required. A special resolution means a resolution passed by a majority of not less than 2/3 of the votes cast by the shareholders who voted in respect of that resolution or signed by all the shareholders entitled to vote on that resolution. There are no requirements applicable to changing the rights of holders of shares of Westport that are more significant than those required by law.

Subject to the Business Corporations Act (Alberta), the annual meeting of shareholders is convoked by the directors of Westport at such time as the directors may determine, provided that such meeting shall be held not later than 15 months after the holding of the last preceding annual meeting. Extraordinary general meetings of shareholders may be convoked at any time by the directors of Westport. Meetings of shareholders are held at such place as the directors may determine.
The board of directors has the power to call a special meeting of shareholders at any time.
The only persons entitled to be present at a meeting of shareholders shall be those entitled to vote thereat, the directors and auditors of Westport, and others who, although not entitled to vote, are entitled or required under any provision of the Business Corporations Act (Alberta) or Articles or By-laws to be present at the meeting.

There are no known limitations on the rights to own securities, including the rights of non-resident or foreign shareholders to hold or exercise voting rights except that, in accordance with the Business Corporations Act (Alberta), the corporation is generally prohibited from holding shares in itself and subsidiaries are limited as to the number of shares of Westport that they may own and the period of time over which they may own such shares.

There are no By-law provisions governing the ownership threshold above which shareholder ownership must be disclosed.

There are no significant differences that management is aware of, in the law applicable to Westport in the areas outlined above in Canada versus the United States.

C. Material Contracts
EDC Loan Agreement

EDC is Canada's export credit agency, providing financing, insurance, bonding, trade knowledge and connections to support Canadian companies. To bolster liquidity and support the Westport LNG HPDI 2.0 fuel system program launch and commercialization, Westport entered into a $20 million secured term loan agreement in December 2017 with EDC. Since that time, there have been several amendments, with the most recent occurring in May 2024. At that time, the security structure was revised to align with the launch of the HPDI joint venture. The maturity date of the loan remains September 15, 2026

D. Exchange Controls
Canada has no system of exchange controls. There are no Canadian restrictions on the repatriation of capital or earnings of Canadian public company to non-resident investors. There are no laws in Canada or exchange restrictions affecting the remittance of dividends, profits, interest, royalties and other payments to non-resident holders of the Company’s securities, except as discussed in “Item 10.E. Taxation” below.

E. Taxation
The following summary discusses certain material U.S. and Canadian tax considerations related to the holding and disposition of common shares as of the hereof. Prospective purchasers of our common shares are advised to consult their own tax advisers concerning the consequences under the tax laws of the country of which they are resident or in which they are otherwise subject to tax of making an investment in our common shares.

Canadian Federal Income Tax Considerations

The Company believes the following is a brief summary of the material principal Canadian federal income tax consequences to a U.S. Holder (as defined below) of common shares of the Company who deals at arm’s length with the Company, holds the shares as capital property and who, for the purposes of the Income Tax Act (Canada) (the “Tax Act”) and the Canada — U.S. Income Tax Convention (1980) (the “Treaty”), is at all relevant times resident in the U.S., is not and is not deemed to be resident in Canada and does not use or hold and is not deemed to use or hold the shares in carrying on a business in Canada. Special rules, which are not discussed below, may apply to a U.S. Holder that is an insurer that carries on business in Canada and elsewhere. U.S. Holders are urged to consult their own tax advisors with respect to their particular circumstances.

This summary is based upon the current provisions of the Tax Act, the regulations thereunder in force at the date hereof, all specific proposals to amend such regulations and the Tax Act publicly announced by or on behalf of the Minister of Finance (Canada) prior to the date hereof and the current provisions of the Convention and the current administrative practices of the Canada Revenue Agency published in writing prior to the date hereof. This summary does not otherwise take into account or anticipate any changes in law or administrative practices whether by legislative, governmental or judicial decision or action, nor does it take into account tax laws of any province or territory of Canada or of the U.S. or of any other jurisdiction outside Canada.

For the purposes of the Tax Act, all amounts relating to the acquisition, holding or disposition of the common shares must be converted into Canadian dollars based on the relevant exchange rate applicable thereto.

This summary does not address all aspects of Canadian federal income taxation that may be relevant to any particular U.S. Holder in light of such holder’s individual circumstances. Accordingly, U.S. Holders should consult with their own tax advisors for advice with respect to their own particular circumstances.

Under the Tax Act and the Treaty, a U.S. Holder of common shares will generally be subject to a 15% withholding tax on dividends paid or credited or deemed by the Tax Act to have been paid or credited on such shares. The withholding tax rate is 5% where the U.S. Holder is a corporation that beneficially owns at least 10% of the voting shares of the Company and the dividends may be exempt from such withholding in the case of some U.S. Holders such as qualifying pension funds and charities.

A U.S. Holder will generally not be subject to tax under the Tax Act on any capital gain realized on a disposition of common shares, provided that the shares do not constitute “taxable Canadian property” to the U.S. Holder at the time of disposition. Generally, common shares will not constitute taxable Canadian property to a U.S. Holder provided that such shares are listed on a designated stock exchange (which currently includes the TSXV) at the time of the disposition and,
73

during the 60- month period immediately preceding the disposition, the U.S. Holder, persons with whom the U.S. Holder does not deal at arm’s length, or the U.S. Holder together with all such persons has not owned 25% or more of the issued shares of any series or class of the Company’s capital stock. If the common shares constitute taxable Canadian property to a particular U.S. Holder, any capital gain arising on their disposition may be exempt from Canadian tax under the Convention if at the time of disposition the common shares do not derive their value principally from real property situated in Canada.

U.S. Federal Income Tax Considerations

The following discussion describes the material U.S. federal income tax consequences to U.S. Holders (as defined below) of the purchase, ownership and disposition of our Common Shares, but does not purport to be a complete analysis of all potential tax effects. The effects of other U.S. federal tax laws, such as estate and gift tax laws, and any applicable state, local or non-U.S. tax laws are not discussed. This discussion is based on the U.S. Internal Revenue Code of 1986, as amended (the “Code”), U.S. Treasury regulations promulgated thereunder (the “Treasury Regulations”), judicial decisions, and published rulings and administrative pronouncements of the U.S. Internal Revenue Service (“IRS”), in each case in effect as of the date hereof. These authorities may change or be subject to differing interpretations. Any such change or differing interpretation may be applied retroactively in a manner that could adversely affect a U.S. Holder of our Common Shares. We have not sought and will not seek any rulings from the IRS regarding the matters discussed below. There can be no assurance the IRS or a court will not take a contrary position to that discussed below regarding the tax consequences of the purchase, ownership and disposition of our Common Shares.

This discussion is limited to U.S. Holders that hold our Common Shares as a “capital asset” within the meaning of Section 1221 of the Code (generally, property held for investment). This discussion does not address all U.S. federal income tax consequences relevant to a U.S. Holder’s particular circumstances, including the impact of the Medicare contribution tax on net investment income or the alternative minimum tax. In addition, it does not address consequences relevant to U.S. Holders subject to special rules, including, without limitation:

·U.S. expatriates and former citizens or long-term residents of the United States;
·persons holding our Common Shares as part of a hedge, straddle or other risk reduction strategy or as part of a conversion transaction or other integrated investment;
·banks, insurance companies, and other financial institutions;
·brokers, dealers or traders in securities;
·persons that directly, indirectly or constructively own 10% or more of the total combined voting power or value of all classes of our share capital;
·real estate investment trusts or regulated investment companies;
·S corporations, partnerships or other entities or arrangements treated as partnerships for U.S. federal income tax purposes (and investors therein);
·tax-exempt organizations or governmental organizations;
·persons deemed to own Common Shares under the constructive sale provisions of the Code;
·persons who hold or receive our Common Shares pursuant to the exercise of any employee stock option or otherwise as compensation;
·U.S. persons that do not have the U.S. dollar as their functional currency;
·persons that hold our Common Shares in connection with a trade or business conducted outside of the United States or in connection with a permanent establishment outside of the United States;
·tax-qualified retirement plans; and
·persons subject to special tax accounting rules as a result of any item of gross income with respect to our Common Shares being taken into account in an applicable financial statement.

THIS DISCUSSION IS FOR INFORMATIONAL PURPOSES ONLY AND IS NOT TAX ADVICE. INVESTORS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF OUR COMMON SHARES ARISING UNDER THE U.S.
74

FEDERAL ESTATE OR GIFT TAX LAWS OR UNDER THE LAWS OF ANY STATE, LOCAL OR NON-U.S. TAXING JURISDICTION OR UNDER ANY APPLICABLE INCOME TAX TREATY.

Definition of a U.S. Holder

For purposes of this discussion, a “U.S. Holder” is any beneficial owner of our Common Shares that, for U.S. federal income tax purposes, is or is treated as:
·an individual who is a citizen or resident of the United States;
·a corporation (or entity taxable as a corporation for U.S. federal income tax purposes) created or organized under the laws of the United States, any state thereof, or the District of Columbia;
·an estate, the income of which is subject to U.S. federal income tax regardless of its source; or
·a trust that (1) is subject to the primary supervision of a U.S. court and the control of one or more “United States persons” (within the meaning of Section 7701(a)(30) of the Code), or (2) has a valid election in effect to be treated as a United States person for U.S. federal income tax purposes.

If an entity treated as a partnership for U.S. federal income tax purposes holds our Common Shares, the tax treatment of a partner in the partnership will depend on the status of the partner, the activities of the partnership and certain determinations made at the partner level. Accordingly, partnerships holding our Common Shares and the partners in such partnerships should consult their tax advisors regarding the U.S. federal income tax consequences to them.

Passive Foreign Investment Company

A non-U.S. entity treated as a corporation for U.S. federal income tax purposes generally will be a passive foreign investment company (“PFIC”) for U.S. federal income tax purposes for any taxable year if either:
·at least 75% of its gross income for such year is passive income (such as interest income); or
·at least 50% of the value of its assets (generally based on an average of the quarterly values of the assets) during such year (which may be determined in part by the market value of our Common Shares, which is subject to change) is attributable to assets that produce passive income or are held for the production of passive income.

For this purpose, we will be treated as owning our proportionate share of the assets and earning our proportionate share of the income of any other entity treated as a corporation for U.S. federal income tax purposes in which we own, directly or indirectly, 25% or more (by value) of the stock.

Based on the value of our assets, including goodwill, and the composition of our income, assets and operations for the taxable year ended December 31, 2025, we do not believe that we were a PFIC for U.S. federal income tax purposes for that taxable year. However, we must determine our PFIC status annually based on tests which are factual in nature, and our status in future years will depend on our income, assets and operations in those years. The application of the PFIC rules is subject to uncertainty in several respects, and determinations of value are inherently factual and subject to different interpretations. Changes in the composition of our income or assets, the market value of our Common Shares, and the market value of our assets may cause us to become a PFIC. Accordingly, there can be no assurance that we were not a PFIC for any previous taxable year (including our taxable year ended December 31, 2025) or that we will not be a PFIC for the current taxable year or any future taxable year.

If the Company is considered a PFIC at any time that a U.S. Holder holds our Common Shares, the Company will generally continue to be treated as a PFIC with respect to the U.S. Holder, even if the Company ceases to be a PFIC in subsequent years, unless the U.S. Holder makes a “deemed sale” election. In addition, any gain recognized by the U.S. Holder on a sale or other disposition of the Common Shares, as well as the amount of any “excess distribution” (defined below) received by the U.S. Holder, would be allocated ratably over the U.S. Holder’s holding period for the Common Shares. The amounts allocated to the taxable year of the sale or other disposition (or the taxable year of receipt, in the case of an excess distribution) and to any year before the Company became a PFIC would be taxed as ordinary income. The amount allocated to each other taxable year would be subject to tax at the highest rate in effect for individuals or corporations, as appropriate, for that taxable year, and an interest charge would be imposed. For purposes of these rules, an excess distribution is the amount by which any distribution received by a U.S. Holder on Common Shares exceeds 125% of the average of the annual distributions on the Common Shares received during the preceding three years or the U.S. Holder’s holding period, whichever is shorter.

Certain elections may be available that would result in alternative treatments (such as qualified electing fund treatment or mark-to-market treatment) of our Common Shares if we are considered a PFIC. The adverse consequences resulting from
75

PFIC treatment can be mitigated if a U.S. Holder makes a valid “qualified electing fund” election ("QEF election"), which, among other things, would require the U.S. Holder to include currently in income its pro rata share of the Company’s net capital gain and ordinary earnings, based on earnings and profits as determined for U.S. federal income tax purposes. However, a U.S. Holder can only make a QEF election with respect to our Common Shares if we furnish such U.S. Holder with certain tax information annually. We cannot provide any assurances that we will furnish to U.S. Holders information that may be necessary for U.S. Holders to make a QEF election. U.S. Holders can also mitigate some of the adverse tax consequences resulting from PFIC treatment by making a mark-to-market election with respect to our Common Shares to include in income in each year as ordinary income an amount equal to the increase in value of our Common Shares for that year or a deduction for any decrease in value (but only to the extent of previous mark-to-market gains), provided that our Common Shares are “marketable.” Our Common Shares will be marketable if they are “regularly traded” on certain U.S. stock exchanges (including the Nasdaq) or on a foreign stock exchange that meets certain conditions, as set forth in applicable Treasury Regulations. If we are treated as a PFIC with respect to a U.S. Holder for any taxable year, the U.S. Holder will be deemed to own shares in any of our subsidiaries that are also PFICs. However, an election for mark-to-market treatment generally will not be available with respect to any such subsidiaries.

If the Company is considered a PFIC, a U.S. Holder would also be subject to annual information reporting requirements. Failure to comply with such information reporting requirements may result in significant penalties and may suspend the running of the statute of limitations. U.S. Holders should consult their tax advisors about the potential application of the PFIC rules to an investment in our Common Shares.

U.S. Holders should consult their tax advisors regarding whether we are a PFIC, the tax consequences of owning the Common Shares if we were to be a PFIC, certain elections that may be made that are designed to lessen the adverse tax consequences, and reporting requirements that are applicable to U.S. Holders of stock of a PFIC.

Taxation of Dividends and Other Distributions on the Common Shares

Subject to the PFIC rules discussed above, the gross amount of any distributions we make to you (including the amount of any tax withheld) with respect to our Common Shares generally will be includible in your gross income as dividend income on the date you receive such distribution, but only to the extent the distribution is paid out of our current or accumulated earnings and profits (as determined under U.S. federal income tax principles). The dividends will not be eligible for the dividends-received deduction allowed to corporations in respect of dividends received from other U.S. corporations. To the extent the amount of the distribution exceeds our current and accumulated earnings and profits (as determined under U.S. federal income tax principles), such excess amount will be treated first as a tax-free return of your tax basis in your Common Shares, and then, to the extent such excess amount exceeds your tax basis in your Common Shares, as capital gain. We currently do not, and do not intend to, calculate our earnings and profits under U.S. federal income tax principles. Therefore, you should expect that a distribution will generally be reported as a dividend even if that distribution would otherwise be treated as a non-taxable return of capital or as capital gain under the rules described above.

With respect to certain non-corporate U.S. Holders, including individual U.S. Holders, dividends may be taxed at the lower capital gain rates applicable to qualified dividend income, provided (1)(a) we are eligible for the benefits of the United States-Canada income tax treaty (the “Treaty”), or (b) the dividends are with respect to Common Shares that are readily tradable on an established securities market in the United States, (2) the Company is neither a PFIC nor treated as such with respect to you (as discussed above) for either the taxable year in which the dividend was paid or the preceding taxable year, and (3) certain other requirements (including holding period and at risk requirements) are met. We have given notice to the Nasdaq, which for this purpose is an established securities market in the United States, of the offering of the Common Shares offered by this prospectus supplement and the prospectus. The determination of whether a dividend qualifies for the preferential tax rates described above must be made at the time the dividend is paid. Although we do not believe we were a PFIC for the taxable year ended December 31, 2025, whether we are treated as a PFIC for any taxable year will depend on factual circumstances during such year, and therefore there can be no assurance that we will not be a PFIC for the taxable year in which such dividend is paid.

The amount of any distribution paid in a currency other than U.S. dollars will be equal to the U.S. dollar value of such currency on the date such distribution is includible in your income, regardless of whether the payment is in fact converted into U.S. dollars at that time. If a distribution in a foreign currency is converted into U.S. dollars on the day it is received, the U.S. Holder will not be required to recognize foreign currency gain or loss with respect to such distribution. Any gain or loss on a conversion or other disposition of the foreign currency for a different U.S. dollar amount on a later date general will be U.S. source ordinary income or loss. The amount of any distribution of property other than cash will be the fair market value of such property on the date of distribution.

Any dividends will generally constitute foreign-source income for foreign tax credit limitation purposes. If the dividends are taxed as qualified dividend income (as discussed above), the amount of the dividend taken into account for purposes of calculating the foreign tax credit limitation in general will be limited to the gross amount of the dividend, multiplied by the
76

reduced tax rate applicable to qualified dividend income and divided by the highest tax rate normally applicable to dividends. The limitation on foreign taxes eligible for credit is calculated separately with respect to specific classes of income. For this purpose, dividends paid by us with respect to our Common Shares will generally constitute passive category income but could, in the case of certain U.S. Holders, constitute general category income. However, if the Company is a “United States-owned foreign corporation,” solely for foreign tax credit purposes, a portion of the dividends allocable the Company's U.S.-source earnings and profits may be re-characterized as U.S. source income. A “United States-owned foreign corporation” is any foreign corporation in which United States persons own, directly or indirectly, 50% or more (by vote or by value) of the stock. Under an exception, dividends will not be allocated to U.S.-source income if less than 10% of the earnings and profits of a United States-owned foreign corporation are attributable to sources within the United States. We cannot provide any assurances that we will not be characterized as a “United States-owned foreign corporation”. If we are a United States-owned foreign corporation and 10% or more of our earnings and profits are attributable to sources within the United States, the portion of the dividends paid on the Common Shares allocable to our United States source earnings and profits would be treated as U.S.-source income, and this treatment could adversely affect a U.S. Holder’s ability to credit any foreign tax withheld from such dividends against such holder’s U.S. federal income liability. The rules relating to the determination of the U.S. foreign tax credit are complex. U.S. Holders should consult their tax advisors regarding the availability of a foreign tax credit in their particular circumstances and the possibility of claiming an itemized deduction (in lieu of the foreign tax credit) for any foreign taxes paid or withheld.

If Canadian withholding taxes apply to any dividends paid to you with respect to the Common Shares, subject to certain conditions and limitations (including specific holding period and at risk rules), such withholding taxes may be treated as foreign taxes eligible for credit against your U.S. federal income tax liability. If tax is withheld at a rate in excess of the rate applicable to a U.S. Holder under the Treaty, the U.S. Holder may not be entitled to credits for the excess amount, even if the procedures for claiming refunds and the practical likelihood that refunds would be made available in a timely fashion were uncertain. Pursuant to applicable Treasury Regulations, if a U.S. Holder is not eligible for the Treaty or depending on the nature of the Canadian withholding tax, the U.S. Holder may not be able to claim a foreign tax credit arising from Canadian withholding tax imposed on dividends, although the IRS has provided temporary relief from the application of certain aspects of these regulations until new guidance or regulations are issued. Instead of claiming a credit, you may elect to deduct such taxes in computing taxable income, subject to applicable limitations. If a refund of the tax withheld is available under the applicable laws of Canada or under the Treaty, the amount of tax withheld that is refundable will not be eligible for such credit against your U.S. federal income tax liability (and will not be eligible for the deduction against your U.S. federal taxable income).

The rules relating to the determination of the foreign tax credit are particularly complex, and each U.S. Holder should consult its tax advisor regarding the availability of a U.S. foreign tax credit in its particular circumstances, including its eligibility for benefits under the Treaty and the potential impact of the applicable Treasury Regulations and the temporary IRS relief as well as the possibility of claiming a deduction (in lieu of the U.S. foreign tax credit).

Taxation of Disposition of Common Shares

Subject to the PFIC rules discussed above, upon a taxable sale or other taxable disposition of our Common Shares, you generally will recognize capital gain or loss for U.S. federal income tax purposes in an amount equal to the difference between the amount realized (including the amount of any tax withheld) and your tax basis in such Common Shares. Your tax basis in your Common Shares generally will equal the cost of such Common Shares. Any gain or loss on the sale or other disposition of such Common Shares generally will be treated as U.S.-source income or loss, and treated as long-term capital gain or loss if your holding period in such Common Shares at the time of the disposition exceeds one year. Because capital gain on the sale or other disposition of our Common Shares generally will be treated as U.S.-source gain, in the event any Canadian tax (including withholding tax) is imposed upon such sale or other disposition, you may not be able to utilize foreign tax credits unless (1) the gain is resourced as foreign-source under the provisions of the Treaty and you elect to apply the Treaty or (2) you have foreign-source income or gain in the same category from other sources. Long-term capital gain of non-corporate U.S. Holders generally will be subject to U.S. federal income tax at reduced tax rates. The deductibility of capital losses is subject to significant limitations.

The rules relating to the determination of the foreign tax credit are particularly complex, and each U.S. Holder should consult its tax advisor regarding the availability of a U.S. foreign tax credit in its particular circumstances, including its eligibility for benefits under the Treaty and the potential impact of the applicable Treasury Regulations and the temporary IRS relief as well as the possibility of claiming a deduction (in lieu of the U.S. foreign tax credit).

Information Reporting and Backup Withholding

Payments of distributions with respect to our Common Shares and proceeds from the sale, exchange or redemption of our Common Shares that are made within the United States or through certain U.S.-related financial intermediaries generally are subject to information reporting to the IRS and may be subject to U.S. backup withholding. Backup withholding will
77

not apply, however, to a U.S. Holder that furnishes a correct taxpayer identification number and makes any other required certification or that is otherwise exempt from backup withholding. U.S. Holders that are required to establish their exempt status generally must provide such certification on IRS Form W-9. You should consult your tax advisor regarding the application of the U.S. information reporting and backup withholding rules.

Backup withholding is not an additional tax. Amounts withheld as backup withholding may be credited against your U.S. federal income tax liability, and you may obtain a refund of any excess amounts withheld under the backup withholding rules by filing the appropriate claim for refund with the IRS and furnishing any required information in a timely manner.

Information with respect to Foreign Financial Assets

Individuals and certain entities that have U.S. individual owners or beneficiaries may be required to report information on IRS Form 8938 relating to an interest in our Common Shares, subject to certain exceptions (including an exception for our Common Shares held in accounts maintained by certain financial institutions). Penalties can apply if a U.S. Holder fails to satisfy such reporting requirements, and the statute of limitations on the assessment and collection of all U.S. federal income taxes of such U.S. Holder for the related tax year may not close before the date which is three years after the date on which a required IRS Form 8938 is filed. You should consult your tax advisor regarding the effect, if any, of reporting requirements on your ownership and disposition of our Common Shares.

THE DISCUSSION OF MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS SET FORTH ABOVE IS NOT INTENDED TO CONSTITUTE A COMPLETE ANALYSIS OF ALL TAX CONSIDERATIONS APPLICABLE TO AN INVESTMENT IN OUR COMMON SHARES. INVESTORS SHOULD CONSULT THEIR TAX ADVISORS ABOUT THE APPLICATION OF THE U.S. FEDERAL TAX RULES TO THEIR PARTICULAR CIRCUMSTANCES, AS WELL AS THE STATE, LOCAL, NON-U.S. AND OTHER TAX CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF OUR COMMON SHARES.

Our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended ("Exchange Act"), are designed to provide reasonable assurance that information required to be disclosed in the reports that we file or submit under the Exchange Act and applicable Canadian securities law requirements is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms and applicable Canadian securities law requirements, and that such information is accumulated and communicated to our management, including our Chief Executive Officer ("CEO") and Chief Financial Officer ("CFO") (our principal executive officer and principal financial officer, respectively), as appropriate to allow timely decisions regarding required disclosures.
We evaluated the effectiveness of our internal controls over financial reporting as of December 31, 2025 with the participation, and under the supervision of our management, including our CEO and CFO. Based upon this evaluation, our CEO and CFO concluded that as of December 31, 2025, our internal controls and procedures over financial reporting were effective for the period.
Management's Report on Internal Control Over Financial Reporting
Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act. Internal control over financial reporting is a process designed by, or under the supervision of, our CEO and CFO and effected by our board of directors, management, and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of our consolidated financial statements for external reporting purposes in accordance with U.S. GAAP and the requirements of the SEC, as applicable. There are inherent limitations in the effectiveness of internal control over financial reporting, including the possibility that misstatements may not be prevented or detected.
79

Because of these inherent limitations, internal control systems, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system's objectives will be met, and no evaluation of controls can provide absolute assurance that all control issues have been detected. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under potential future conditions, regardless of how remote. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.
Management, including the CEO and CFO, has evaluated the effectiveness of our internal control over financial reporting, based on the criteria in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, management has determined that our internal control over financial reporting was effective as of December 31, 2025.
KPMG LLP ("KPMG"), our independent registered public accounting firm, has audited our annual financial statements and expressed an unqualified opinion thereon. KPMG has also expressed an unqualified opinion on the effective operation of our internal control over financial reporting as of December 31, 2025. KPMG's audit report on effectiveness of internal control over financial reporting is included in the Annual Financial Statements.
Changes in Internal Control Over Financial Reporting
As a result of the disposal of the Light-Duty segment, during the year ended December 31, 2025, there have been changes to our internal controls over financial reporting. There were no other changes to our internal controls over financial reporting that materially affected, or are reasonably likely to materially affect our internal controls over financial reporting.
Item 16. [Reserved]
Item 16A. Audit committee financial expert
On April 23, 2026, the Company’s Audit Committee consists of Brad Kotush, Eileen Wheatman, and Karl Viktor-Schaller. Each member of the Audit Committee, in the opinion of the directors, is independent (as determined under Rule 10A-3 of the Exchange Act and Nasdaq Rule 5605(a)(2)) and financially literate.
The Company’s Board of Directors has determined that Brad Kotush and Eileen Wheatman qualify as "audit committee financial experts" (as defined in Item 407 of Regulation S-K under the Exchange Act) and are independent (as determined under Exchange Act Rule 10A-3 and Nasdaq Rule 5605(a)(2)).
Item 16B. Code of Ethics
We have adopted a Code of Conduct that applies to our directors, officers (including our principal executive officer, principal financial officer and principal accounting officer or controller) and employees. Our Code of Conduct is designed to promote honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest, compliance with applicable laws and regulations, and full, fair, accurate, timely and understandable disclosure in reports and documents that we file with or submit to regulatory authorities. Our Code of Conduct was amended during the financial year ended December 31 2025. The amendments did not result in any material changes to the standards of conduct applicable to our directors, officers and employees. Our Code of Conduct is publicly available on our website at investors.westport.com/governance/governance-documents/.

Policies and Procedures of the Audit Committee
Mandate
The mandate of the Audit Committee as prescribed by the Board is set out in the Audit Committee Charter. The latest version of our Audit Committee Charter is available on our website at investors.westport.com/governance/governance-documents/.
Non-Audit Services
The Audit Committee is mandated to review the provision of non-audit services and consider the effect of any such services on the independence of the external auditors.
The SEC rules on auditor independence as they relate to public companies include prohibitions or restrictions on services that may be provided by auditors to their audit clients and require that all services provided to a listed entity audit client, including its subsidiaries, be pre-approved by the client's audit committee. In accordance with those rules, the Audit Committee has approved, adopted and made effective a preapproval policy as part of the Audit Committee Charter. That policy requires that any proposed audit and permitted non-audit services be provided by the external auditors to Westport or its subsidiaries must receive prior approval from the Audit Committee. As a practical matter, the policy also contemplates that such proposals may be received and considered by the Audit Committee Chair (or such other member of the Audit Committee who may be delegated authority to approve audit and permitted non-audit services) for approval of the proposal on behalf of the Audit Committee, in which case the Audit Committee Chair will then inform the Audit Committee of any approvals granted at the next scheduled meeting.
Item 16D. Exemptions from the Listing Standards for Audit Committees
Not applicable.

Item 16E. Purchases of Equity Securities by the Issuer and Affiliated Purchasers
Not applicable.

Item 16F. Change in Registrant's Certifying Accountant
Not applicable.

Item 16G. Corporate Governance
As a foreign private issuer incorporated under the laws of Alberta, Canada and listed on the Nasdaq Stock Market ("Nasdaq"), the Company is permitted to follow Canadian corporate governance practices in lieu of certain corporate governance requirements otherwise applicable to U.S. domestic issuers listed on the Nasdaq, pursuant to Nasdaq Listing Rule 5615(a)(3). A description of the significant ways in which our governance practices differ from those followed by domestic companies pursuant to Rule 5600 of the Nasdaq Rules is as follows:

•Rule 5620(c) requires that each listed company provide for a quorum for any meeting of the holders of the listed company’s common stock that is not less than 33 1/3% of the listed company’s outstanding shares of common stock entitled to vote. The Company’s bylaws provide for a quorum of at least two persons present in person and holding or representing by proxy not less than 25% of the shares entitled to vote at the meeting.

•Rule 5605(d)(1)(D) requires that each listed company adopt a formal written compensation committee charter that specifies, among other things, the specific compensation committee responsibilities and authority set forth in Rule 5605(d)(3). The Company’s Human Resources and Compensation Committee Charter does not specify the specific compensation committee responsibilities and authority set forth in Rule 5605(d)(3).

We may elect to take advantage of additional Canadian corporate governance practices in lieu of certain corporate governance requirements otherwise applicable to U.S. domestic issuers listed on the Nasdaq in the future.

We follow the corporate governance practices required by applicable Canadian federal and provincial corporate and securities laws, including National Instrument 58-101 - Disclosure of Corporate Governance Practices and National Policy 58-201 - Corporate Governance Guidelines.

Item 16H. Mine Safety Disclosure
Not applicable.

Item 16I. Disclosure Regarding Foreign Jurisdictions that Prevent Inspections
Not applicable.

Item 16J. Insider trading policies
The Company has adopted an Insider Trading Policy to provide directors, officers and employees with guidelines regarding trading in securities of the Company. The rules and procedures outlined in the Insider Trading Policy are intended to prevent improper trading in securities of Westport and any other company in respect of which material non-public information is obtained by Westport and the improper communication of material non-public information regarding Westport or such other companies. The foregoing description of the Insider Trading Policy does not purport to be complete and is qualified in its entirety by the terms and conditions of the Insider Trading Policy, a copy of which is attached hereto as Exhibit 11.1 and is incorporated herein by reference.

Item 16K. Cybersecurity
The Company's Information Technology ("IT") function manages its cyber resilience efforts through a variety of relevant organizational functions. The Company's cybersecurity program includes the administrative, technical and organizational measures intended to protect the confidentiality, integrity, and availability of its information and systems. It is led by the head of IT, who has over 25 years of experience in information technology and operational systems at global manufacturing and operations-focused organizations. In carrying out its responsibilities, management also engages external cybersecurity and information security specialists to support the assessment, prevention, detection, mitigation, and remediation of cybersecurity risks and incidents.

The IT function's mandate includes defining the Company's cyber resilience framework, identifying and measuring risks, building the business continuity strategy and tactics, disaster recovery plans, capturing key business information security risks beyond IT and reporting any incidents. The head of IT provides regular updates to the Audit Committee with analysis,
82

mitigation strategies and incident reporting being reported to the Board. In 2025, cybersecurity, information security, and artificial intelligence awareness training programs were completed by employees, focused on developing awareness of threats and how to recognize them. Working in concert with an information security partner, the Company has implemented global security structures and measures, with breach detection, prevention, event management and reporting.

During the first quarter of 2026, the Company identified a cybersecurity incident involving unauthorized access to certain information systems. Upon detection, the Company activated its incident response protocols, including containment measures, engagement of external cybersecurity advisors, and notification of senior management and the Audit Committee. The Company is undertaking remediation of the affected systems and implementing targeted enhancements to its cybersecurity controls and monitoring capabilities. The Company is also carrying out notification and regulatory reporting activities where required under applicable laws. As of the date of this Form 20-F, management believes the incident has not had a material impact on the Company, including its operations, business strategy, results of operations, or financial condition; however we may incur further costs and liabilities arising from this incident. Additionally, the Company has not identified risks from any other known cybersecurity threats that have materially affected or are reasonably likely to materially affect us, including our operations, business strategy, results of operations, or financial condition.

The Board receives prompt and timely information from management on any cybersecurity or information security incident that may pose significant risk to our organization and continues to receive regular reports on the incident until its conclusion. In 2025, there were no reported incidents of information or cyber breaches, however the Company identified a cybersecurity incident during the first quarter of 2026, as described above. In addition, the Board receives management reports on key developments and incidents at the industry level and received cybersecurity and artificial intelligence educational sessions in 2025 to ensure members continue to remain informed about evolving trends.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors
Westport Fuel Systems Inc.:

Opinion on the Consolidated Financial Statements
We have audited the accompanying consolidated balance sheets of Westport Fuel Systems Inc. (and subsidiaries) (the Company) as of December 31, 2025 and 2024, the related consolidated statements of operations and comprehensive loss, shareholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2025, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025, and 2024, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2025, in conformity with U.S. generally accepted accounting principles.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated April 23, 2026, expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.
Going Concern
The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 2 to the consolidated financial statements, the Company has suffered recurring losses from operations and, based on the projected capital expenditures, debt servicing obligations, and operating requirements under the current business plan, is projecting insufficient cash flows that raise substantial doubt about its ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 2. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.
Basis for Opinion
These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.


F-2

Critical Audit Matters
Critical audit matters are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. We determined that there are no critical audit matters.

Report of Independent Registered Public Accounting Firm


To the Shareholders and Board of Directors
Westport Fuel Systems Inc.:

Opinion on Internal Control Over Financial Reporting
We have audited Westport Fuel Systems, Inc.’s (and subsidiaries’) (the Company) internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2025 and 2024, the related consolidated statements of operations and comprehensive loss, shareholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2025, and the related notes (collectively, the consolidated financial statements), and our report dated April 23, 2026, expressed an unqualified opinion on those consolidated financial statements.
Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control Over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
F-4

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Notes to Consolidated Financial Statements
(Expressed in thousands of United States dollars)
Years ended December 31, 2025, 2024, and 2023
1. Company organization and operations:
Westport Fuel Systems Inc. (the “Company”) was incorporated under the Business Corporations Act (Alberta) on March 20, 1995. Westport is a technology and innovation company connecting synergistic technologies to power a cleaner tomorrow. As a supplier of affordable, alternative fuel, low-emissions transportation technologies, the Company designs, manufactures, and supplies advanced components and systems that enable the transition from traditional fuels to alternative energy solutions. The Company's technologies support a wide range of alternative fuels – including natural gas, renewable natural gas, and hydrogen – enabling OEMs and commercial transportation industries to meet performance demands, regulatory requirements, and climate targets in a cost-effective way.
2. Liquidity and going concern:
For year ended December 31, 2025, the Company reported an operating loss from continuing operations of $14,229. The Company continues to sustain operating losses and to use cash to support its business activities. As at December 31, 2025, the Company had cash and cash equivalents of $27,158 and an outstanding term loan, net of deferred financing fees, with Export Development Canada ("EDC") of $2,924. The Company has a minimum cash covenant under the term loan of $15,000. If the Company's cash and cash equivalents fall below the minimum cash requirement, the Company may be required to repay the outstanding amount of the term loan.
On July 29, 2025, the Company closed the sale of the Light-Duty segment to a wholly-owned investment vehicle of Heliaca Investments (the "Purchaser"), a Netherlands based investment firm supported by Ramphastos Investments Management B.V., a Dutch venture capital and private equity firm for total consideration of $59,975 (€51,424) (note 5).
On September 29, 2025, the Company filed a final short form base shelf prospectus (the "Shelf Prospectus") with the relevant Canadian securities regulatory authorities allowing the Company to offer up to US $100,000 of common shares, preferred shares, subscription receipts, warrants, debt securities, or units, or any combination thereof during the 25-month period that the Shelf Prospectus will be effective.
In connection with preparing consolidated financial statements for each annual and interim reporting period, the Company is required to evaluate whether there are conditions or events, considered in aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date the financial statements are issued. Substantial doubt exists when conditions and events, considered in aggregate, indicate that it is probable a company will be unable to meet its obligations as they become due within one year after the date the consolidated financial statements are issued. This evaluation initially does not take into consideration the potential mitigating effect of management’s plans and actions that have not been fully implemented as of the date the financial statements are issued. When substantial doubt exists, management evaluates whether the mitigating effect of its plans sufficiently alleviates substantial doubt about the Company’s ability to continue as a going concern. The mitigating effect of management’s plans, however, is only considered if both: (1) it is probable the plans will be effectively implemented within one year after the date the financial statements are issued; and (2) it is probable the plans, when implemented, will mitigate the relevant conditions or events that raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date the financial statements are issued.
Based on the Company's projected capital expenditures, debt servicing obligations and operating requirements under its current business plan, management is projecting that its existing cash and cash equivalents will not be sufficient to fund its operations through the next twelve months from the date of the issuance of these consolidated financial statements. These conditions raise substantial doubt about the Company's ability to continue as a going concern within one year after the date these consolidated financial statements are issued.
Management plans to improve the Company's liquidity position by raising funds from the public markets, borrowing debt and other financing alternatives. These plans are not final and are subject to market and other conditions not in the Company's control. As such, there can be no assurance that the Company will be successful in obtaining sufficient funding. Accordingly, management has concluded under the accounting standards that these plans do not alleviate the substantial doubt about the Company's ability to continue as a going concern.

Notes to Consolidated Financial Statements
(Expressed in thousands of United States dollars except share and per share amounts)
Years ended December 31, 2025, 2024, and 2023
These consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the ordinary course of business. The consolidated financial statements do not include any adjustments related to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that may be necessary if the Company were unable to continue as a going concern.
3. Significant accounting policies:
(a)    Basis of presentation:
The consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany balances and transactions have been eliminated on consolidation.
These consolidated financial statements are presented in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). In the statement of operations and comprehensive loss, certain prior period figures have been adjusted to conform to current period presentation.
(b)    Foreign currency translation:
The Company’s functional currency is the Canadian dollar and its reporting currency for its consolidated financial statement presentation is the United States dollar ("U.S. Dollar"). The functional currencies for the Company's significant subsidiaries include the following: U.S. Dollar, Canadian dollar, Euro, and Chinese Renminbi (“RMB”). The Company translates assets and liabilities of non-U.S. dollar functional currency operations using the period end exchange rates, shareholders’ equity balances using the weighted average of historical exchange rates, and revenues and expenses using the monthly average rate for the period with the resulting exchange differences recognized in other comprehensive income (loss). 
Transactions that are denominated in currencies other than the functional currencies of the Company’s or its subsidiaries' operations are translated at the rates in effect on the date of the transaction. Foreign currency denominated monetary assets and liabilities are translated to the applicable functional currency at the exchange rates in effect on the balance sheet date. Non-monetary assets and liabilities are translated at the historical exchange rate. All foreign exchange gains and losses are recognized in the condensed consolidated interim statements of operations, except for the translation gains and losses arising from available-for-sale instruments, which are recorded through other comprehensive income (loss) until realized through disposal or impairment.
Except as otherwise noted, all amounts in these financial statements are presented in U.S. dollars. For the years presented, the Company used the following exchange rates:
 Year-end exchange rate as at:Average for the year ended:
December 31,December 31,
 202520242023202520242023
Canadian dollar$1.37 $1.44 $1.32 $1.40 $1.37 $1.35 
Euro$0.85 $0.96 $0.90 $0.89 $0.92 $0.92 
RMB$6.99 $7.30 $7.10 $7.19 $7.20 $7.08 
(c)    Cash and cash equivalents (including restricted cash):
Cash and cash equivalents include cash on hand, term deposits, banker acceptances and guaranteed investment certificates with maturities of ninety days or less when acquired. Cash and cash equivalents at December 31, 2025 include restricted cash of $363 (2024 - $406; 2023 - $103). Restricted cash at December 31, 2025, 2024, and 2023 is related to cash used to secure a letter of credit.

Years ended December 31, 2025, 2024, and 2023
(d)    Accounts receivable, net:
The accounts receivable balance reflects invoiced and accrued revenue and is presented net of an allowance for credit losses. The Company expects most of its accounts receivable balances to continue to come from large customers as it supplies the majority of its products and services through distributors and OEMs. The Company establishes current expected credit losses ("CECL") for pools of assets with similar risk characteristics by evaluating historical levels of credit losses, current economic conditions that may affect a customer's ability to pay, and creditworthiness of significant customers. When specific customers are identified as no longer sharing the same risk profile as their current pool, they are removed from the pool and evaluated separately. The Company, in the normal course of business, monitors the financial condition of its customers and reviews the credit history of each new customer. When the Company becomes aware of a specific customer's inability to meet its financial obligations to the Company (such as in the case of bankruptcy filings or material deterioration in the customer's operating results or financial position, and payment experiences), the Company records a specific credit loss provision to reduce the customer's related accounts receivable to its estimated net realizable value. If circumstances related to specific customers change, the Company's estimates of the recoverability of accounts receivable balances could be further adjusted.
(e)    Inventories:
The Company’s inventories consist of the Company’s fuel system products (finished goods), work-in-progress, purchased parts and materials. Inventories are recorded at the lower of cost and net realizable value. Cost is determined based on weighted average costing method. The cost of fuel system product inventories, assembled parts and work-in-progress includes materials, labour and production overhead, including depreciation. The Company records inventory write-downs based on an analysis of excess and obsolete inventories determined primarily by future demand forecasts. In addition, the Company records a liability for firm, noncancellable, and unconditional purchase commitments with manufacturers for quantities in excess of the Company’s future demand forecast consistent with its valuation of excess and obsolete inventory.
(f)    Property, plant and equipment:
Property, plant and equipment are stated at cost. Depreciation is provided for as follows:
AssetsBasisRate
Computer equipment & software Straight-line 3 years
Furniture and fixtures Straight-line 5 years
Machinery and equipment Straight-line 
5 - 10 years
Leasehold improvements Straight-line Shorter of lease term or estimated useful life
Depreciation expense on machinery and equipment used in the production and manufacturing process is included in cost of revenue. All other depreciation is included in depreciation and amortization expense in the consolidated statements of operations and comprehensive loss.
(g)    Long-term investments and impairment:
The Company accounts for investments in which it has significant influence, including variable interest entities ("VIEs") for which the Company is not the primary beneficiary, using the equity method of accounting. Under the equity method, the Company recognizes its share of income or loss from equity accounted investees in the statement of operations with a corresponding change in long-term investments. Any additional capital contributions to investees are capitalized and any dividends paid or payable are credited against long-term investments.
The Company identified Cespira Canada LP and Cespira Sweden AB as VIEs, as the entities are dependent on funding from their owners. The funding and ownership interests of the entities are split on a 55/45 basis between the owners of the VIEs. The voting rights and power to exercise control is shared equally on a 50/50 basis between the owners of the VIEs.

(Expressed in thousands of United States dollars except share and per share amounts)
Years ended December 31, 2025, 2024, and 2023
Therefore, the Company has determined that it is not the primary beneficiary of the VIEs. The Company's maximum exposure to loss are its investments in Cespira Canada LP and Cespira Sweden AB and the current outstanding accounts receivables balances.
The Company evaluates its long-term investments for impairment when an investee has recognized a series of operating losses or recognizes an impairment loss in its financial statements. In such an event, the Company measures the fair value of the investee against its carrying amount. The Company estimates the fair value of its long-term investments under the equity method using the expected future cash flows discounted at a rate commensurate with the risks of the investee.
If the fair value is lower than carrying amount, the Company will consider whether the loss is other than temporary. Factors considered when evaluating whether a loss is other than temporary include:
(i) the length of time and extent to which the fair value of the investee has been less than its carrying amount
(ii) the investee's financial condition and near term prospects, including recent operating losses or specific events that may negatively influence its future earnings potential; and
(iii) the intent and ability of the Company to retain its investment for a period of time sufficient to allow for an anticipated recovery in fair value.
When the Company concludes the loss is other than temporary, it records an impairment loss against the investment's carrying amount and reports the impairment loss in the Company's consolidated statement of operations and comprehensive loss.
(h)    Financial liabilities:
Accounts payable and accrued liabilities, short-term debt and long-term debt are measured at amortized cost. Transaction costs relating to long-term debt are netted against long-term debt and are amortized using the effective interest rate method.
(i)    Research and development costs:
Research and development costs are expensed as incurred and are recorded net of funding received or receivable.
(j)    Impairment of long-lived assets:
The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. If such conditions exist, assets are considered impaired if the sum of the undiscounted expected future cash flows expected to result from the use and eventual disposition of an asset is less than its carrying amount. An impairment loss is measured at the amount by which the carrying amount of the asset exceeds its fair value. When quoted market prices are not available, the Company uses the expected future cash flows discounted at a rate commensurate with the risks associated with the recovery of the asset as an estimate of fair value.
(k)    Warranty liability:
Estimated warranty costs are recognized at the time the Company sells its products and are included in cost of revenue. The Company provides warranty coverage on products sold from the date the products are put into service by customers. Warranty liability represents the Company’s best estimate of warranty costs expected to be incurred during the warranty period. Furthermore, the current portion of warranty liability represents the Company’s best estimate of the costs to be incurred in the next twelve-month period. The Company uses historical failure rates and costs to repair defective products to estimate the warranty liability. New product launches require a greater use of judgment in developing estimates until claims experience becomes available. Product specific experience is typically available four or five quarters after product launch, with a clear experience trend not evident until eight to twelve quarters after launch. The Company records warranty expense for new products using historical experience from previous generations in the first year, a blend of actual product

and historical experience in the second year and product specific experience thereafter. The amount payable by the Company and the timing will depend on actual failure rates and cost to repair failures of its products.
(m)    Revenue recognition:
The Company generates revenues primarily from product sales. Product revenues are derived from standard product sales contracts and purchase orders from customers. The Company recognizes revenue when a customer obtains control of the goods. Determining the timing of the transfer of control, at a point in time or over time, requires judgment. On standard product sales contracts, revenues are recognized when customers obtain control of the product, that is when transfer of title and risks and rewards of ownership of goods have passed and when obligation to pay is considered certain. Invoices are generated and revenue is recognized at that point in time. Provisions for warranties are made at the time of sale. Service revenue is recognized over time as performance obligations are satisfied.
(n)    Income taxes:
The Company accounts for income taxes using the asset and liability method. Under this method, deferred income tax assets and liabilities are determined based on the temporary differences between the accounting basis and tax basis of the assets and liabilities and for loss carry-forwards, tax credits and other tax attributes, using the enacted tax rates in effect for the years in which the differences are expected to reverse. The effect of a change in tax rates on deferred income tax assets and liabilities is recognized in income in the period that includes the enactment date. 
The Company recognizes deferred income tax assets to the extent the assets are more-likely-than-not to be realized. In making such a determination, the Company considers all available positive and negative evidence including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies and results of recent operations. If it is determined that, based on all available evidence, it is more-likely-than-not that some or all of the deferred income tax assets will not be realized, a valuation allowance is provided to reduce the deferred income tax assets.
The Company uses a two-step process to recognize and measure the income tax benefit of uncertain tax positions taken or expected to be taken in a tax return. The tax benefit from an uncertain tax position is recognized if it is more-likely-than-not that the position will be sustained upon examination by a tax authority based solely on the technical merits of the position. A tax benefit that meets the more-likely-than-not recognition threshold is measured as the largest amount that is greater than 50% likely to be realized upon settlement with the tax authority. To the extent a full benefit is not expected to be realized, an income tax liability is established. Any change in judgment related to the expected resolution of an uncertain tax position is recognized in the year of such a change.
Interest and penalties related to income taxes are included as a component of income tax expense.
(o)    Leases:
The Company determines if an arrangement is a lease or contains a lease at inception. Operating leases with lease terms greater than 12 months are included in current and non-current assets, current and non-current liabilities in the consolidated balance sheet. Assets under finance leases are included in property, plant and equipment and the related lease liabilities in current and non-current liabilities in the consolidated balance sheets.
Operating lease and finance lease right-of-use (“ROU”) assets and operating lease liabilities are recognized based on the present value of the future lease payments over the lease term at the commencement date. As the rate implicit in the lease is not readily determinable for the Company’s operating leases, an incremental borrowing rate is generally used to determine the present value of future lease payments. The incremental borrowing rate for each lease is based on the Company’s estimated borrowing rate over a similar term to that of the lease payments, adjusted for various factors including collateralization, location and currency.
The operating lease expenses are recognized on a straight-line basis over the lease term and included in cost of revenue and operating expenses. Short-term leases, which have an initial term of 12 months or less, are not recorded in the consolidated balance sheets.

(p)    Stock-based compensation:
The Company measures stock-based awards at fair value on the date of the grant and expense the awards over the requisite service period of employees or consultants. The fair value of stock options is determined using the fair market value at the time of grant. The fair value of restricted stock units (“RSUs") and Deferred Share Units (“DSUs") are determined using the share price of the Company at the date of grant. The fair value of performance based restricted stock units (“PSUs”) is determined using the Monte Carlo Simulation Model. Stock-based compensation expense related to stock option awards is recognized over the requisite service period on a graded vesting basis. Forfeitures are accounted for as they occur. Stock-based awards are either equity settled or cash settled. Cash-settled awards are recorded as a liability based on the Company's share price on the date of grant and remeasured at the end of each reporting period over the vesting term.
The Company’s estimates may be impacted by certain variables including, but not limited to, stock price volatility, employee stock option exercise behaviors, additional stock option grants, the Company’s performance and related tax impacts.
(q)    Earnings (loss) per common share:
Basic earnings or loss per share includes no potential dilution and is computed by dividing the earnings or loss attributable to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings or loss per share reflect the potential dilution of securities that could share in the earnings or loss of our Company. Dilutive securities are excluded from the calculation of our diluted weighted average common shares outstanding if their effect would be anti-dilutive based on the treasury stock method or due to a net loss from continuing operations. Common Shares that have not been released under the Company’s stock based plan or are being held in trust for purposes of the Company’s restricted stock unit program have been excluded from the calculation of basic earnings per share.
(r)    Contingent consideration:
The Company may enter into contingent consideration arrangements whereby a buyer pays the seller additional consideration after transaction close upon the achievement of certain milestones, performance-based metrics, or other objectives as agreed to per the terms of the related agreement.
The Company accounts for contingent considerations that are not identified as derivatives using the loss recovery approach. The Company does not recognize any contingent receivable at inception and will recognize a contingent gain when such gain is realized or realizable.
(s)    Held-for-sale disposal group and discontinued operations:
The Company classifies a component of an entity as a held-for-sale disposal group when it has been disposed of during the period, or it has met all of the held-for-sale criteria under Topic 205 - Presentation of Financial Statements at the balance sheet reporting date. A held-for-sale disposal group is measured at the lower of its carrying amount and fair value less cost to sell. If the fair value less cost to sell is lower than its carrying amount, a loss is recognized to write down the carrying amount of the disposal group as a whole.
After a disposal group has been classified as held-for-sale, management may decide to reverse its plan to divest, or circumstances may change so that the disposal group no longer meets the held-for-sale criteria. In such instances, the Company would reclassify the disposal group's assets and liabilities on the balance sheet as held-and-used and remeasured on the date of reclassification.

4. New accounting pronouncements
New accounting standard adopted in 2025:
ASU 2023-09 - Income Taxes (Topic 740): Improvement to Income Tax Disclosures
The ASU amends the rules on income tax disclosures by modifying or eliminating certain existing income tax disclosure requirements in addition to establishing new requirements. The amendments address investor requests for more transparency about income taxes, including jurisdictional information, by requiring consistent categories and greater disaggregation of information. The ASU's two primary amendments relate to the rate reconciliation and income taxes paid annual disclosures.
Reconciling items presented in the rate reconciliation are in dollar amounts and percentages, and are disaggregated into specified categories with certain reconciling items further broken out by nature and/or jurisdiction using a 5% threshold of domestic federal taxes. Income taxes paid are disaggregated between federal, provincial/territorial, and foreign taxing jurisdictions using a 5% threshold of total income taxes paid net of refunds received.
The ASU is effective for annual periods beginning after December 15, 2024. The Company adopted this standard prospectively in the fourth quarter of 2025 with an effective date of January 1, 2025 and has included the disaggregation of rate reconciliation items and income tax payments by specified categories, nature and/or jurisdiction as described within note 14 - Income taxes.
Upcoming accounting standards not yet adopted in 2025:
ASU 2024-03 - Disaggregation of Income Statement Expenses (Subtopic 202-40)
The ASU aims to provide stakeholders a clearer understanding of an entity's expenses and enhance their ability to assess performance, forecast expenses and evaluate the entity's potential for future cash flows. The ASU amends the rules on income statement expense disclosures and requires public business entities to disaggregate and disclose, in tabular format in the notes to financial statements, specified categories of expenses contained within certain income statement expense line items; to integrate certain amounts that were already required to be disclosed under current GAAP with the new disaggregation requirements and to qualitatively disclose descriptions of the amounts remaining that were not separately disaggregated. The ASU also requires public business entities to disclose the total amount of selling expenses and, in annual reporting periods, an entity's definition of those selling expenses. This ASU does not change or remove the current disclosure requirements of expense line items on the face of the Consolidated Statements of Income.
The amendments in this ASU are effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The amendments in this ASU should be applied either prospectively to Consolidated Financial Statements issued for reporting periods following the effective date, or retrospectively to any or all prior periods presented in the Consolidated Financial Statements. While this guidance may have an impact on the disclosures, the Company does not expect this guidance to have a material impact on its financial position, operations, and cash flows.
The Company has evaluated other recently issued ASU's effective on or after December 31, 2025 and does not expect their adoption to have a material impact on its consolidated financial statements.

5. Discontinued operations
On May 15, 2025, shareholders approved management's plan to sell the Light-Duty segment in accordance with the terms of the sale and purchase agreement ("SPA") dated March 30, 2025. On July 14, 2025, the Company entered into a short-term loan with the Purchaser for $5,839 (€5,000). The loan was subsequently repaid on July 29, 2025.
On July 29, 2025, the Company closed the sale of its Light-Duty segment to the Purchaser for consideration of $59,975 (€51,424). The Company recorded a $37,313 loss on disposal of the operations in respect of the sale. The Company received proceeds of $50,763 (€43,424) from the Purchaser in cash and other consideration. The Company expects to receive a further $9,391 (€8,000) from proceeds held in escrow, which are included in a holdback receivable (note 6) and other long-term assets (note 10). The proceeds held in escrow will be released to the Company in three tranches by early 2026, early 2027 and mid-year 2027. Purchase price adjustments may impact the final proceeds received from the Purchaser pending satisfaction of certain general representations and warranties provided by the Company that are customary in nature. Subsequent to year-end, the Company received $6,493 (€5,500) for the first of three tranches.

Further, up to $3,790 (€3,250) in potential earnouts will be payable to the Company if certain conditions are achieved in accordance with the terms and conditions of the sale and purchase agreement.

If either owner is unable to fund Cespira when funding is requested in accordance with the joint venture agreement, a convertible loan may be extended from the other owner to fund all or a part of the funding requested. The convertible loan may settle in ownership interest in Cespira in the event that the borrowing party is unable to fulfill the repayment terms.

The loan is secured by share pledges in the Company's equity interest in Cespira. Throughout the term of certain of these financing arrangements, the Company is required to meet certain financial and non-financial covenants.

shares were issued and any fractional shares were rounded down to the nearest whole common shares. The number of outstanding common shares and share units issued have been retroactively adjusted for all periods presented.
During the year ended December 31, 2025, the Company issued 92,279 common shares, net of cancellations, upon exercises of share units (year ended December 31, 2024 – 108,432 common shares; December 31, 2023 - 44,186). The Company issues shares from treasury to satisfy share unit exercises.
(a)    Share Units ("Units"):
The value assigned to issued Units and the amounts accrued are recorded as other equity instruments. As Units are exercised or vested and the underlying shares are issued from treasury of the Company, the value is reclassified to share capital.
The Westport Omnibus Plan aims to advance the Company's interests by encouraging employees, consultants and non-employee directors to receive equity-based compensation and incentives. The plan outlines the stock-based options types, eligibility and vesting terms.

RSUs typically vest over a three year period so the actual value received by the individual depends on the share price on the day such RSUs are settled for common shares, not the date of grant. Values of PSUs are determined using the Monte–Carlo Simulation Model and vest only when the performance criteria has been met within the evaluation period. Vesting of DSUs shall occur immediately prior to the resignation, retirement or termination of directorship, in accordance with the terms of Westport's Omnibus Plan and settled in cash.
As at December 31, 2025, $719 of compensation expense related to Units has yet to be recognized in results from operations and will be recognized ratably over 1.5 years.

16. Commitments and contingencies:
(a)     Contractual commitments
The Company is a party to a variety of agreements in the ordinary course of business under which it is obligated to indemnify a third party with respect to certain matters. Typically, these obligations arise as a result of contracts for sale of the Company’s product to customers where the Company provides indemnification against losses arising from matters such as product liabilities. The potential impact on the Company’s financial results is not subject to reasonable estimation because considerable uncertainty exists as to whether claims will be made and the final outcome of potential claims. To date, the Company has not incurred significant costs related to these types of indemnifications.
(b)     Contingencies
The Company is engaged in certain legal actions and tax audits in the ordinary course of business and believes that, based on the information currently available, the ultimate outcome of these actions will not have a material adverse effect on our operating results, liquidity or financial position.
17. Segment information:
The Company discloses segment information under three reportable segments, consistent with the manner in which its Chief Operating Decision Maker ("CODM") evaluates its businesses. The Company's CODM is its Chief Executive Officer. These segments are the strategic pillars of the Company and are managed separately as each represents a specific grouping of related automotive components and systems. The reportable segments are further described below. In prior years, the Company presented its results under four reportable segments: Light-Duty, High-Pressure Controls, Heavy-Duty OEM, and Cespira.
On July 29, 2025, the Company sold its Light-Duty segment to the Purchaser (note 5). The Company now reports its results in the following three reportable segments: High-Pressure Controls, Heavy-Duty OEM, and Cespira. The prior year comparatives were recast to reflect this change in reportable segments.
•High-Pressure Controls: This segment's products include fuel cell and hydrogen fuel system solutions and components.
•Heavy-Duty OEM: Prior to June 3, 2024, this segment's products include HPDI related fuel system solutions and components. Subsequently, this segment's operations were related to the transitional services agreement between the Company and Cespira for inventory and contract manufacturing. The transitional service agreement for these services ended on June 30, 2025 when Cespira completed their independent set up for inventory manufacturing.
•Cespira: This segment's products include HPDI related fuel system solutions and components after June 3, 2024.
Segment earnings or losses before income taxes, interest, depreciation, and amortization ("Segment EBITDA") is the measure of segment profitability used by the Company. The accounting policies of our reportable segments are the same as those applied in our consolidated financial statements. Management prepared the financial results of the Company's reportable segments on basis that is consistent with the manner in which Management internally disaggregates financial information to assist in making internal operating decisions. Certain common costs and expenses were allocated among segments and presented differently than the Company would for stand-alone financial information prepared in accordance with GAAP. These include certain costs and expenses of shared services, such as IT, human resources, legal, finance and supply chain management. Segment EBITDA is not defined under US GAAP and may not be comparable to similarly titled measures used by other companies and should not be considered a substitute for net earnings or other results reported in accordance with GAAP.
The Company's CODM uses segment EBITDA disclosed below to evaluate the performance of its reportable segments. The Company believes Segment EBITDA is most reflective of the operational profitability or loss of its reportable

18. Financial instruments:
Financial risk management
The Company has exposure to liquidity risk, credit risk, foreign currency risk and interest rate risk.
Liquidity risk
Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they are due. The Company has a history of losses and mostly negative cash flows from operations since inception. At December 31, 2025, the Company has $27,158 of cash, cash equivalents including $363 in restricted cash (see note 3(c)).

 $22,642 $23,220 $21,620 $945 $655 
Credit risk
Credit risk arises from the potential that a counterparty to a financial instrument fails to meet its contractual obligations and arises principally from the Company’s accounts receivable.
The Company is exposed to credit risk with respect to uncertainties as to timing and amount of collectability of accounts receivable. As at December 31, 2025, 20% (December 31, 2024 - 11%; December 31, 2023 - 91%) of accounts receivable relate to customer receivables, and 80% (December 31, 2024 - 89%; December 31, 2023 - 9%) relate to amounts due from holdback receivable, related parties and income tax authorities for value added taxes and other tax related refunds. In order to minimize the risk of loss for customer receivables, the Company’s extension of credit to customers involves review and approval by senior management as well as progress payments as contracts are executed. Most sales are invoiced with payment terms in the range of 30 days to 90 days. Refer to note 3(d) for the Company's policy with respect to an allowance for credit losses.
Foreign currency risk
Foreign currency risk is the risk that the fair value of future cash flows of financial instruments will fluctuate because of changes in foreign currency exchange rates. The Company conducts a significant portion of its business activities in foreign currencies, primarily the U.S. dollar and the Euro. The Company are subject to foreign currency exchange rate risk to the extent that our costs are denominated in currencies other than those in which the Company earn revenues. In addition, since the Company's consolidated financial statements are reported in U.S. dollars, changes in foreign currency exchange rates between the U.S. dollar and other currencies have had, and will continue to have, an impact on the Company's results of operations, financial condition and cash flows.
Cash and cash equivalents, accounts receivable, accounts payable, and long-term debt that are denominated in foreign currencies will be affected by changes in the exchange rate between the Canadian dollar and these foreign currencies. The Company’s functional currency is the Canadian dollar.
A 5% increase/decrease in the relative value of the U.S. dollar against the Canadian dollar and Euro compared to the exchange rates in effect for the year ended December 31, 2025 would have resulted in lower/higher income from operations of approximately $441. This assumes a consistent 5% appreciation in the U.S. dollar against the Canadian dollar and the Euro throughout the fiscal year. The timing of changes in the relative value of the U.S. dollar can affect the magnitude of the impact that fluctuations in foreign exchange rates have on our income from operations.
Interest rate risk
Interest rate risk is the risk that the fair value of future cash flows of a financial instrument will fluctuate because of changes in market interest rates. The Company is subject to interest rate risk on its term loan with variable rates of interest.
If interest rates for the year ended December 31, 2025 had increased or decreased by 200 basis points, with all other variables held constant, net loss for the year ended December 31, 2025 would have increased or decreased by $58.

Fair value of financial instruments
As at December 31, 2025, cash and cash equivalents are measured at fair value on a recurring basis and are included in Level 1.
The carrying amounts reported in the consolidated balance sheets for cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate their fair values due to the short-term period to maturity of these instruments.
The long-term investments represent the Company's interests in Cespira are accounted for using the equity method.
The carrying values reported in the consolidated balance sheets for obligations under operating leases, which are based upon discounted cash flows, approximate their fair values.
The carrying values of the term loan facilities included in the long-term debt (note 12) are carried at amortized costs, which approximate their respective fair values as at December 31, 2025.
The Company categorizes its fair value measurements for items measured at fair value on a recurring basis into three categories as follows:
 Level 1 –Unadjusted quoted prices in active markets for identical assets or liabilities.
   
 Level 2 –Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
   
 Level 3 –Inputs for the asset or liability that are not based on observable market data (unobservable inputs).
When available, the Company uses quoted market prices to determine fair value and classify such items in Level 1. When necessary, Level 2 valuations are performed based on quoted market prices for similar instruments in active markets and/or model–derived valuations with inputs that are observable in active markets. Level 3 valuations are undertaken in the absence of reliable Level 1 or Level 2 information.
