TABLE OF CONTENTS

PART I

Sono-Tek Corporation (the “Company”, “Sono-Tek”, “We” or “Our”) is the world leader in the design and manufacture of ultrasonic coating systems for applying precise, thin film coatings to add functional properties, protect or strengthen surfaces on parts and components for the microelectronics/electronics, alternative energy, medical, industrial and emerging research & development/other markets. We design and manufacture custom-engineered ultrasonic coating systems incorporating our patented technology, in combination with strong applications engineering knowledge, to assist our customers in achieving their desired coating solutions.

Our ultrasonic nozzle systems use high frequency ultrasonic vibrations that atomize liquids into minute drops that can be applied to surfaces at low velocity providing microscopic layers of protective and other useful materials over a wide variety of surfaces, including glass and metals. Our equipment solutions are environmentally-friendly, efficient and highly reliable. They enable dramatic reductions in overspray, savings in raw materials, water and energy usage and provide improved process repeatability, transfer efficiency, high uniformity and reduced emissions. We serve a variety of industries and applications and have a broad base of customers.

The applications that are employing our unique coating technology and expertise have been expanding as the advantages of ultrasonic coatings are more broadly recognized. The original application of our technology was to coat the inner surface of blood collection tubes used for medical diagnostic testing. Our products enable the application of a thin and uniform coating of material that prevents coagulation of blood. Following that initial breakthrough, our technology was then used for applying uniform flux coatings to printed circuit boards, a critical part of the fabrication process for all electronic devices. A later application for much larger surfaces was to address the many challenges that glass manufacturers faced. They needed a solution for specialized glass applications in the construction and automotive industries. Among other things, our ultrasonic nozzles are used to provide coatings that improve durability, create filters, increase clarity, reduce reflection, enable conductivity, and enhance safety. We have invested significant resources to enhance our market diversity by leveraging our core ultrasonic coating technology. As a result, we have increased our portfolio of products, the industries we serve, and the countries in which we sell our products.

We were founded by the inventor of the ultrasonic nozzle, Dr. Harvey Berger, and incorporated in New York on March 21, 1975. We became a public company in 1987 and our stock is traded on the Nasdaq Capital Market. Our corporate offices are located in Milton, New York where our production facilities are co-located. We also have a sales and service office in Singapore and an application process development laboratory in Guangzhou, China. We are ISO 9001 qualified since registering in September 1998 and have been recertified annually since then.

Our fiscal year ends on February 28, except in leap years when it ends on February 29. We refer to the fiscal year ended February 28, 2026 as “fiscal 2026” and use similar protocol for previous fiscal years.

Our Products, Markets and Customers

Our products are used in a wide range of applications. We provide our customers a broad offering of ultrasonic spray coating equipment solutions custom suited for their requirements and we continually expand our offerings to address new applications. Our products include fully integrated Multi-Axis Coating Systems, Integrated Coating Systems, Fluxing Systems, OEM Systems and other related systems. We invest heavily in research and development to continually bring to market new solutions for our customers, to increase our market share and to solve high value problems in manufacturing.

Our Multi-Axis Coating Systems, Integrated Coating Systems and Fluxing Systems provide complete fully integrated solutions for our customers, while we created the Universal Align to offer our customers subsystems that integrate our nozzles and generators for incorporation into their original equipment.

We have built our brand and reputation on providing high quality, highly reliable products that provide consistent performance for critical applications in demanding operating environments. Our surface coating solutions are used in 24/7 work schedules, under harsh and challenging manufacturing environments, where they provide value in a continuous and dependable fashion.

We target the following markets where our product quality and consistency and application knowledge are valued by our customers:

Our principal customers include original equipment manufacturers, distributors and end users of our products in the industries that we serve.

Our products are sold primarily through our direct sales personnel, select independent distributors and through sales representatives around the world that are trained on our technologies and products. Our distributors are typically experts in their industries and recognize the significant value that our technology provides their customers. We provide extensive training and on-site support with our direct sales force and application engineers, who also respond to leads generated by our web site and the trade shows in which we participate. To grow sales, we continue to strengthen our laboratory and applications engineering personnel and support our worldwide process development labs with additional ultrasonic coating equipment, in conjunction with sponsoring various technical training seminars for our distribution network.

We also provide application consulting services enabling our customers to rely on our surface coating expertise and specific customer process optimization. We offer these services both in our application process development laboratory and at our customers’ sites where we can assist in the design and development of customized coating systems.

We are a global business, and our geographical sales mix can vary from year to year depending on the timing of orders from customers. In fiscal 2026, 33% of our sales were from outside the U.S. and Canada.

Our Strengths

From our core strengths and capabilities, we:

Our Strategy

Our strategy is to further advance the use of ultrasonic coating technologies for the microscopic coating of surfaces in a broader array of applications which enable better outcomes for our customers’ products and processes. We believe product superiority is imperative and that it is attained through the extensive experience that we have in the coatings industry, our proprietary manufacturing know-how and skills, and our unique work force that we have built over the years.

We intend to leverage our innovative technologies, proprietary know-how, unique talent and experience, and global reach to:

To accomplish these objectives, we believe that we must judiciously deploy our monetary and human capital to expand our presence in our targeted markets and create broader offerings for our customers.

Availability of Raw Materials

Historically, we have not been adversely impacted by the availability of raw materials or components used in the manufacture of our products.

Generally, except in instances of pandemic related supply chain issues, all raw materials used in our products are available from many different domestic suppliers, who may themselves be subject to international raw material availability. We purchase circuit board assemblies and sheet metal components from a wide range of suppliers throughout the world.

We carefully manage our inventory using lean manufacturing processes.

Research and Development

We believe that our long-term growth is dependent upon the development and commercialization of ultrasonic coating technologies to solve customers’ high value problems across a wide spectrum of applications in various industries, while also advancing the utility of our core technology. During fiscal 2026 and fiscal 2025, we spent $2,554,000 and $2,724,000, respectively, on research and development activities related to new products and services and the ongoing improvement of existing products and services. As a percentage of sales, research and development expenses were 12% and 13% in fiscal 2026 and 2025, respectively.

Intellectual Property

Our business is based in part on the technology covered by our U.S. patents. We also rely on unpatented know-how in the design and production of our nozzle systems, subsystems and complete solutions. We have executed non-disclosure and non-compete agreements with all of our employees to safeguard our intellectual property. We execute reciprocal non-disclosure agreements with our key customers to safeguard any jointly developed intellectual property.

Competition

We operate in competitive markets in many of our industry segments. We compete against alternative coating technologies, as well as global and regional manufacturers of nozzles and other products based on price, quality, product features, application engineering and follow-up service. We maintain our competitive position by providing highly effective solutions that meet our customers’ requirements and needs. In several emerging markets, we encounter less competition compared to more established markets based on the uniqueness of our ultrasonic technology in these applications.

Information Regarding Sales Outside the United States and Canada

During fiscal 2026 and fiscal 2025, net sales to customers outside the U.S. and Canada accounted for approximately $6,963,000, or 33% of total net sales, and $7,998,000, or 39% of total net sales, respectively. Our international sales have been impacted by changes in trade policies, including the imposition of new tariffs or other trade restrictions.

Employees

As of February 28, 2026, we employed 79 full-time and 10 part-time employees. We believe that relations with our employees are generally good.

Available Information

We are subject to the informational requirements of the Securities Exchange Act of 1934, as amended. Therefore, we file “reports, proxy statements and other information with the Securities and Exchange Commission (“SEC”). The SEC maintains a website at www.sec.gov that contains the reports, proxy statements and other information for registrants that file electronically, as we do. Additionally, these reports may be read and copied at the Public Reference Room of the SEC at 100 F Street, N.E., Washington, DC 20549. Information regarding the SEC’s Public Reference Room may be obtained by calling 1-800-SEC-0330.

We maintain a website at http://www.sono-tek.com. On our site, we provide copies of our Forms 8-K, 10-K, 10-Q, Proxy and Annual Report as soon as reasonably practicable after filing electronically such material with the SEC. Copies are also available, without charge, from Sono-Tek Corporation, 2012 Route 9W, Milton, NY 12547.

We do not have long-term commitments for significant revenues with most of our customers and may be unable to retain existing customers, attract new customers or replace departing customers with new customers that can provide comparable revenues and profit margins.

Because we generally do not obtain firm, long-term volume purchase commitments from our customers, most of our sales are derived from individual purchase orders. We remain dependent upon securing new purchase orders in the future to sustain and grow our revenues. Accordingly, there is no assurance that our revenues and business will grow in the future. Our failure to maintain and expand our customer relationships could materially and adversely affect our business and results of operations.

In recent years, a few major customers and distributors have accounted for a significant portion of our revenue. Our revenue could decline if we are unable to maintain or develop relationships with additional customers or distributors and our results of operations could be adversely affected if any one of these customers is unable to meet their financial obligations to us.

For the year ended February 28, 2026, one customer accounted for approximately 28% of our net sales. For the year ended February 28, 2025, one customer accounted for approximately 11% of our net sales. If we are unable to diversify our customer base, our future results could be heavily dependent on these customers and distributors. Our dependence on a limited number of customers and distributors means that the loss of a major customer or distributor or any reduction in orders by a major customer or distributor would materially reduce our net sales and adversely affect our results of operations. As we continue our transition from primarily selling ultrasonic nozzles and components to a more complex business providing complete equipment solutions and higher value subsystems, we expect that sales to relatively few customers will continue to account for a significant percentage of our net sales for the foreseeable future; however, these customers or our other customers, may not use our products at current levels in the future, if at all. Customer purchase orders may be delayed or cancelled, and order volume levels can be changed with loss of deposit as the only penalty. We may not be able to replace cancelled, delayed, or reduced purchase orders with new orders. If any one of these customers reduces its demand for our products, it will likely have a material adverse effect on our operations.

Furthermore, a significant portion of our accounts receivables is concentrated with a few major customers, who may not be able to meet their financial obligations to us. The failure of any such customers to pay amounts owed to us in a timely fashion or at all could have an adverse effect on our results of operations. The Company is also exposed to credit risk on its accounts receivable, and this risk is heightened during periods when economic conditions worsen. The Company's outstanding receivables are not covered by collateral or credit insurance. The Company's exposure to credit and collectability risk on its receivables may also be higher in certain international markets, and its ability to mitigate such risks may be limited. While the Company has procedures to monitor and limit exposure to credit risk on its receivables, there can be no assurance such procedures will effectively limit our credit risk and avoid losses.

We may need to raise additional funds to develop our business, which may adversely affect our future growth.

We may finance a portion of our anticipated future growth and possibly future strategic acquisitions through public or private equity offerings or debt financings. Additional funds may not be available when we need them on terms that are acceptable to us, or at all. If adequate funds are not available, we may be required to delay or reduce the scope of, our plans to grow our revenues or to consummate one or more strategic acquisitions or otherwise to scale back our business plans. In addition, we could be forced to reduce or forego attractive business opportunities. To the extent that we raise additional funds by issuing equity securities, our stockholders may experience significant dilution. In addition, debt financing, if available, may involve restrictive covenants. We may seek to access the public or private capital markets whenever conditions are favorable, even if we do not have an immediate need for additional capital at that time. Our access to the financial markets and the pricing and terms we receive in the financial markets could be adversely impacted by various factors, including changes in financial markets and interest rates.

Changes in United States trade policy, including the imposition of tariffs and the resulting consequences, may have a material adverse impact on our business and results of operations.

The US government has adopted a new approach to trade policy and in some cases to renegotiate, or potentially terminate, certain existing bilateral or multi-lateral trade agreements. It has also initiated or is considering the imposition of tariffs on certain foreign goods, including electronic components and devices, metal alloys, and potentially other parts used in our systems and machinery. Changes in United States trade policy could result in one or more of US trading partners adopting responsive trade policies making it more difficult or costly for us to export our products to those countries. These measures could also result in increased costs for goods imported into the United States. This in turn could require us to increase prices to our customers which may reduce demand, or, if we are unable to increase prices, result in lowering our margin on products sold.

We cannot predict future trade policy or the terms of any renegotiated trade agreements and their impact on our business. The adoption and expansion of trade restrictions, the occurrence of a trade war, or other governmental action related to tariffs or trade agreements or policies has the potential to adversely impact demand for our products, our costs, our customers, our suppliers, and the US economy, which in turn could adversely impact our business, financial condition and results of operations.

We may be adversely affected by global and regional economic conditions and military, legislative, regulatory and political developments.

We sell our products around the world, and we expect to continue to derive a substantial portion of sales from outside the U.S. In addition, we are currently operating in a period of economic uncertainty and capital markets disruption, which has been impacted by geopolitical instability due to ongoing military conflicts in various regions, including war with Iran. Our business, financial condition and results of operations could be materially adversely affected by any negative impact on the global economy and capital markets resulting from such conflicts or broader geopolitical tensions.

Customers or suppliers may experience cash flow problems and as a result, may modify, delay or cancel plans to purchase our products, and suppliers may significantly and quickly increase their prices or reduce their output. Additionally, if customers are not successful in generating sufficient revenue or are precluded from securing financing, they may not be able to pay, or may delay payment of, amounts owed to us. Any inability of current and/or potential customers to purchase our products and/or to pay us for our products may adversely affect our sales, earnings and cash flow. Sales and earnings could also be affected by our ability to manage the risks and uncertainties associated with the application of local legal requirements or the enforceability of laws and contractual obligations, trade protection measures, changes in tax laws, regional political instability, war, terrorist activities, severe or prolonged adverse weather conditions and natural disasters as well as health epidemics or pandemics.

Geopolitical instability and the ongoing military conflict in Iran could adversely affect our business, financial condition, and results of operations.

The ongoing military conflict between the United States and Iran, which escalated in early 2026, has created significant volatility in global markets and remains a source of substantial uncertainty. We are subject to risks associated with this conflict, which may include, but are not limited to:

The extent to which the conflict impacts our results will depend on future developments, including the duration of hostilities, the potential for regional escalation involving neighboring states, and the effectiveness of any diplomatic efforts to restore stability. Any of these factors could have a material adverse effect on our business, financial condition, and results of operations.

Our success will depend, to a large degree, on the expertise and experience of the members of our management team, the loss of whom could have a material adverse effect on our business.

Our success is, to a large degree, dependent upon the expertise and experience of the management team and its ability to attract and retain qualified personnel who are technically proficient. The loss of the services of one or more of such personnel could have a material adverse effect on our business. Our business may be adversely affected if we are unable to continue to attract and retain such personnel.

We will need to add qualified additional personnel as we expand our business, and we may not be able to employ such persons, which could affect our ability to expand and have a material adverse effect on our business.

 To expand our product offerings and customer base, we will need to hire additional qualified personnel. We may not be able to identify such persons, and even if we identify them, we may not have the funds or ability to employ them, which could have a material adverse effect on our business.

Although we have not experienced any material disruptions due to labor shortages to date, we have observed an overall tightening and increasingly competitive labor market. A sustained labor shortage or increased turnover rates within our employee base as a result of general macroeconomic factors, could lead to increased costs, such as increased overtime to meet demand and increased wage rates to attract and retain employees, and could negatively affect our ability to complete our projects according to the required schedule or otherwise efficiently operate our business. If we are unable to hire and retain employees capable of performing at a high level, or if mitigation measures we may take to respond to a decrease in labor availability, such as overtime and third-party outsourcing, have unintended negative effects, our business could be adversely affected. An overall labor shortage, lack of skilled labor, increased turnover or labor inflation, caused by general macroeconomic factors, could have a material adverse impact on our operations, results of operations, liquidity or cash flows.

If we are unable to manage our expected growth, our business may be materially and adversely affected.

We expect to expand our operations, including by expanding our internal resources, making possible acquisitions and entering new markets, and we intend to continue to focus on rapid growth, including organic growth and possibly acquisitions. The growth of our business could place significant strain on our management, operational and financial resources. To manage our future growth, we could be required to improve existing or implement new operational or financial systems, procedures and controls or expand, train and manage a growing employee base. Our failure to accomplish any of these tasks could materially and adversely affect our business. Even if we are successful in integrating future acquisitions into our existing operations, we may not derive the benefits, such as operational or administrative synergies, that we expected from such acquisitions, which may result in the investment of our capital resources without realizing the expected returns on such investment.

Our inability to protect our intellectual property rights could negatively affect our business and results of operations.

Our ability to compete effectively depends in part upon developing, maintaining and/or protecting intellectual property rights relevant to our ultrasonic nozzles and coating processes. We rely principally on a combination of patent protection, trade secret laws, confidentiality and non-disclosure agreements, and trusted business relationships to establish, maintain and protect the intellectual property rights relevant to our business. These measures, however, may not be adequate in every given case to permit us to gain or retain any competitive advantage, particularly in those countries where the laws do not protect our proprietary rights as fully as in the United States.

Where we consider it appropriate, we may seek patent protection in the United States on technologies used in, or relating to, our ultrasonic nozzles, applications and manufacturing processes. The issuance of a patent is not conclusive as to its scope, validity and enforceability. Thus, any patent or patent application which may issue into a patent held by us could be challenged, invalidated or held unenforceable in litigation or proceedings before the U.S. Patent and Trademark Office and/or other patent tribunals or circumvented by others. No consistent policy regarding the breadth of patent claims has emerged to date in the United States, and the landscape could become more uncertain in view of future rule changes by the United States Patent and Trademark Office, the introduction of patent reform legislation and decisions in patent law cases by United States federal courts. The patent landscape outside the United States is even less predictable. As a result, the validity and enforceability of patents cannot be predicted with certainty. In addition, we may fail to apply for patents on important technologies or product candidates in a timely fashion, if at all, and our existing and future patents may not be sufficiently broad to prevent others from utilizing our technologies or from developing competing products or technologies.

Our patent strategy involves complex legal and factual questions. Our ability to maintain and solidify our proprietary technology may depend in part upon our success in obtaining patent rights and enforcing those rights once granted or licensed. Our issued patents and those that may be issued in the future may be challenged, invalidated, rendered unenforceable or circumvented, which could limit our ability to prevent competitors from marketing similar or related products, or shorten the term of patent protection that we may have for our products, processes and enabling technologies. In addition, the rights granted under any issued patents may not provide us with competitive advantages against competitors with similar technology. Furthermore, our competitors may independently develop similar technologies, duplicate technology developed by us or otherwise possess intellectual property rights that could limit our ability to manufacture our products and operate our business.

We also rely on trade secret protection for our confidential and proprietary information. Trade secrets, however, can be difficult to protect. We may not be able to maintain our technology or know-how as trade secrets, and competitors may develop or acquire equally valuable or more valuable technology or know-how related to the manufacture of comparable ultrasonic nozzles. We also seek to protect our confidential and proprietary information, in part, by requiring all employees, consultants and business partners to execute confidentiality and/or nondisclosure agreements upon the commencement of any employment, consulting arrangement or engagement with us. These agreements generally require that all confidential and proprietary information developed by the employee, consultant, or business partner, or made known to the employee, consultant or business partner by us, during the course of the relationship with us, be kept confidential and not disclosed to third parties. These agreements may be breached and may not provide adequate remedies in the event of breach. To the extent that our employees, consultants, or business partners use intellectual property owned by others in their work for and/or with us, disputes could arise as to the rights in related or resulting technologies, know-how or inventions. Moreover, while we also require customers and vendors to execute agreements containing confidentiality and/or nondisclosure provisions, we may not have obtained such agreements from all of our customers and vendors. In addition, our trade secrets may otherwise become known or be independently discovered by competitors, customers, or vendors. Such customers or vendors may also be subject to laws and regulations that require them to disclose information that we would otherwise seek to keep confidential.

Moreover, others may independently develop and obtain patents covering technologies that are similar or superior to the product forms, applications, or manufacturing processes that we employ. If that happens, we may need to obtain licenses for these technologies and may not be able to obtain licenses on reasonable terms, if at all, which could limit our ability to manufacture our future products and operate our business. In addition, third parties could utilize our intellectual property rights in territories where we do not have intellectual property protection. Such third parties may then try to import products made using our intellectual property rights into the United States or other countries, which could have a material adverse effect on our business.

We could become subject to intellectual property litigation that could be costly, limit or cancel our intellectual property rights, divert time and efforts away from business operations, require us to pay damages and/or otherwise have an adverse material impact on our business.

The success of our business is highly dependent on protecting our intellectual property rights. Unauthorized parties may attempt to copy or otherwise obtain and use our products and/or enabling technologies. Policing the unauthorized use of our intellectual property rights is difficult and expensive, as is enforcing these rights against unauthorized use by others. Identifying unauthorized use of our intellectual property rights is difficult because we may be unable to monitor the processes and/or materials being employed by other parties. The steps we have taken may not prevent unauthorized use of our intellectual property rights, particularly in foreign countries where enforcement of intellectual property rights may be more difficult than in the United States.

Our continued commercial success will also depend in part upon not infringing the patents or violating the intellectual property rights of third parties. We are aware of patents and patent applications generally relating to aspects of our technologies filed by, and issued to, third parties. Nevertheless, we cannot determine with certainty whether such patents or patent applications of other parties may materially affect our ability to conduct our business. There may be existing patents of which we are unaware that we may inadvertently infringe, resulting in claims against us or our customers. If the manufacture, use and/or sale of our products or processes is challenged, or if our product forms or processes conflict with the patent rights of others, third parties could bring legal actions against us or our customers in the United States, Asia, Europe or other countries, claiming damages and seeking to enjoin the manufacturing and/or marketing of our products. Additionally, it is not possible to predict with certainty what patent claims may issue from any relevant third-party pending patent applications. Third parties may be able to obtain patents with claims relating to our product forms, applications and/or manufacturing processes which they could attempt to assert against us or our customers.

In either case, litigation may be necessary to enforce, protect or defend our intellectual property rights or to determine the validity and scope of the intellectual property rights of others. Any litigation could be unsuccessful, cause us to incur substantial costs, divert resources and the efforts of our personnel away from daily operations, harm our reputation and/or result in the impairment of our intellectual property rights. In some cases, litigation may be threatened or brought by a patent holding company or other adverse patent owner who has no relevant product revenues and against which our patents may provide little or no deterrence. If we are found to infringe any patents, we could be required to (1) pay substantial monetary damages, including lost profits, reasonable royalties and/or treble damages if an infringement is found to be willful and/or (2) totally discontinue or substantially modify any products or processes that are found to be in violation of another party’s intellectual property rights. If our competitors are able to use our technology without payment to us, our ability to compete effectively could be harmed.

The markets within which we compete are highly competitive. Many of our competitors have greater financial and other resources than we do and one or more of these competitors could use their greater financial and other resources to gain market share at our expense.

If our business continues to develop as expected, we anticipate that our revenues will continue to grow. If, due to capital constraints or otherwise, we are unable to fulfill our existing backlog in a timely manner and/or procure and timely fulfill our anticipated future backlog, our customers and potential customers may decide to use competing systems or products. If we are unable to fulfill the demand for products and systems in a timely manner, our customers and potential customers may choose to purchase products from our competitors. In addition, we could face new competition from large international or domestic companies with established industrial brands and distribution networks that enter our end markets. Demand for our products may also be affected by our ability to respond to changes in design and functionality, to respond to downward pricing pressure, and to provide shorter lead times for our products than our competitors. If we are unable to respond successfully to these competitive pressures, we could lose market share, which could have an adverse impact on our results. We cannot assure that we will be able to compete successfully in our markets or compete effectively against current and new competitors as our industry continues to evolve.

Rapid technological changes may prevent us from remaining current with our technological resources and maintaining competitive product and service offerings.

The markets in which we and our customers operate are characterized by rapid technological change. Significant technological changes could render our existing and potential new products, systems, and technology obsolete. Our future success will depend, in large part, upon our ability to:

If we are unable to successfully respond to technological change or if we do not respond to it in a cost-effective and timely manner, then our business will be materially and adversely affected. We cannot assure you that we will be successful in responding to changing technology. In addition, technologies developed by others may render our products, systems, and technology uncompetitive or obsolete. Even if we do successfully respond to technological advances, the integration of new technology may require substantial time and expense, and we cannot assure you that we will succeed in adapting our products, systems and technology in a timely and cost-effective manner.

If we are unable to continue to develop new and enhanced products and systems that achieve market acceptance in a timely manner, our competitive position and operating results could be harmed.

Our future success will depend on our ability to continue to develop new and enhanced ultrasonic nozzles and coating systems and related products that achieve market acceptance in a timely and cost-effective manner. The markets in which we and our customers operate are characterized by frequent introductions of new and enhanced products and services, evolving industry standards and regulatory requirements, government incentives and changes in customer needs. The successful development and market acceptance of our products and systems, depends on several factors, including:

We may experience financial or technical difficulties or limitations that could prevent us from introducing new or enhanced products or systems. Furthermore, any of these new or enhanced products and systems could contain problems that are discovered after they are introduced. We may need to significantly modify the design of these products and systems to correct problems. Rapidly changing industry standards and customer preferences and requirements may impede market acceptance of our products and systems.

Development and enhancement of our products and systems will require significant additional investment and could strain our management, financial and operational resources. The lack of market acceptance of our products or systems or our inability to generate sufficient revenues from this development or enhancement to offset their development costs could have a material adverse effect on our business. In addition, we may experience delays or other problems in releasing new products and systems and enhancements, and any such delays or problems may cause customers to forego purchases of our products and systems and to purchase those of our competitors.

We cannot provide assurance that products and systems that we have recently developed or that we develop in the future will achieve market acceptance. If our new products and systems fail to achieve market acceptance, or if we fail to develop new or enhanced products and systems that achieve market acceptance, our growth prospects, operating results and competitive position could be adversely affected.

We manufacture and assemble all our products at one facility. Any prolonged disruption in the operations of this facility would result in a decline in our sales and profitability.

We manufacture and assemble our products and systems at our production facility located in Milton, New York. Any prolonged disruption in the operations of our manufacturing and assembly facility, whether equipment or information technology infrastructure failure, cyber-attacks, labor difficulties, prolonged health emergencies, destruction of or damage to this facility because of a hurricane, earthquake, fire, flood, other catastrophes, and other operational problems would result in a decline in our sales and profitability. In the event of a business interruption at our facility, we may be unable to shift manufacturing and assembly capabilities to alternate locations, accept materials from suppliers or meet customer shipment needs, among other severe consequences. Such an event could have a material and adverse impact on our financial condition and results of our operations.

Failure to obtain adequate supplies of components and raw materials or failure to obtain components or raw materials at affordable prices could negatively affect our ability to supply products to our customers and negatively affect our profit margins.

We use a variety of components and raw materials in the manufacture of our products. As other industries develop products utilizing similar components and raw materials that we use, we may not be able to obtain adequate supplies of components and raw materials required for the manufacture of our existing and future products that would prevent us from supplying products to our customers and materially affect our business. Furthermore, any increased demand for, the raising of tariff rates on, or an increase of non-tariff trade barriers that apply to the components and raw materials that we use could increase the price we must pay to obtain them and could adversely affect our profitability, which would have an adverse effect on our financial results.

Recently, we have encountered challenges in our supply of various materials and components, and electronic components in particular, due to well-documented shortages and constraints in the global supply chain. Lead times for ordered components may vary significantly, and some components used to manufacture our products are provided by a limited number of sources.

We may rely on sub-contractors to meet current demand for our products, and we may need to obtain additional manufacturing capacity to increase production of our existing products or to produce our proposed new products, the failure of which could have a material adverse effect on our operations.

We may not have sufficient internal manufacturing capacity to meet the current demand for our products, and we may need to rely on subcontractors to enable us to meet this demand. Since we may rely on our subcontractors for a significant amount of our production capacity, the loss of the services of our subcontractors would have a material adverse effect on our business. Our plans for the growth of our business rely upon increasing sales of our existing products and systems and developing and marketing new products. We may not have adequate internal manufacturing facilities to substantially increase production of our products and obtaining additional manufacturing capacity in-house could require substantial capital expenditures. We may not have the capital resources to obtain or construct new facilities to expand manufacturing capacity and meet increasing demand for our products, which could have a material adverse effect on our operations. Conversely, any significant decrease in demand for our products could create idle plant capacity and an inability to cover fixed costs, which could adversely impact our results of operations and financial condition.

We are exposed to risks related to our international sales, and the failure to manage these risks could harm our business.

In addition to our net sales to customers within the U.S. and Canada, we may become increasingly dependent on net sales to customers outside the U.S. and Canada as we pursue expanding our business with customers worldwide. In the fiscal years ended February 28, 2026 and February 28, 2025, our net sales outside of the U.S. and Canada accounted for approximately 33% and 39%, respectively, of our total net sales. We continue to expect that a significant portion of our future revenues will be from international sales. As a result, the occurrence of any international, political, economic, or geographic event, including the imposition of tariffs and the onset of trade wars, could result in a significant decline in revenue. There are significant risks associated with conducting operations internationally, requiring significant financial commitments to support such operations. These numerous and sometimes conflicting laws and regulations include internal control and disclosure rules, data privacy and filtering requirements, anti-corruption laws, such as the Foreign Corrupt Practices Act, and other local laws prohibiting corrupt payments to governmental officials, and anti-competition regulations, among others.

Violations of these laws and regulations could result in fines and penalties, criminal sanctions against us, our officers, or our employees, prohibitions on the conduct of our business and on our ability to offer our products and services in one or more countries, and could also materially affect our brand, our international expansion efforts, our ability to attract and retain employees, our business, and our operating results. Although we have implemented policies and procedures designed to ensure compliance with these laws and regulations, there can be no assurance that our employees, contractors, or agents will not violate our policies.

Some of the risks and challenges of conducting business internationally include:

While these factors and the impacts of these factors are difficult to predict, any one or more of them could adversely affect our business, financial condition and results of operations in the future.

Any liability damages resulting from technical faults or failures of our products could be substantial and could materially adversely affect our business and results of operations.

Our products are used by customers and integrated into customers’ machines and systems, and therefore a malfunction or the inadequate design of our products could result in product liability claims. Any liability for damages resulting from technical faults or failures could be substantial and could materially adversely affect our business and results of operations. In addition, a well-publicized actual or perceived problem could adversely affect the market’s perception of our products, which would materially impact our financial condition and operating results.

Inflationary Pressures and Rising Prices for Goods and Services.

Inflation rose sharply beginning in early 2021 and continued rising through 2022, leveling off in 2023 at rates not seen for over 40 years. Although the Federal Reserve has significantly increased interest rates in response to rising inflation, inflationary pressures, driven in part by evolving and uncertain US tariff policies, are currently expected to remain elevated throughout 2026. Small to medium-sized businesses may be impacted more during periods of high inflation as they are not as able to leverage economics of scale to mitigate cost pressures compared to larger businesses. Inflation has the potential to adversely affect our liquidity, business, financial condition and results of operations by increasing our overall cost structure, particularly if we are unable to achieve commensurate increases in the prices we charge our customers. The existence of inflation in the economy has resulted in, and may continue to result in, higher interest rates and capital costs, shipping costs, supply shortages, increased costs of labor, weakening exchange rates and other similar effects. As a result of inflation, we have experienced and may continue to experience, cost increases. Although we may take measures to mitigate the impact of this inflation, if these measures are not effective our business, financial condition, results of operations and liquidity could be materially adversely affected. Even if such measures are effective, there could be a difference between the timing of when these beneficial actions impact our results of operations and when the cost of inflation is incurred.

Reduction or elimination of United States government clean energy initiatives could materially adversely affect our business and results of operations

Since 2022, legislation such as the CLEAN Energy Act, Inflation Reduction Act and the American Renewable Energy Act intended to stimulate growth of the clean energy sector and have contributed to an increase in sales of our systems and products to the clean energy and solar markets. Any reduction or elimination of these government initiatives could have a material adverse effect on sales to these markets and on our total revenues and results of operations.

We could become liable for damages resulting from our manufacturing activities, which could have a material adverse effect on our business or cause us to cease operations.

The nature of our manufacturing operations exposes us to potential claims and liability for environmental damage, personal injury, loss of life and damage to, or destruction of, property. Our manufacturing operations are 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 manufacturing operations may not comply with future laws and regulations, and we may be required to make significant unanticipated capital and operating expenditures to bring our operations within compliance with such evolving regulations. If we fail to comply with applicable environmental laws and regulations, manufacturing guidelines, and workplace safety requirements, governmental authorities may seek to impose fines and penalties on us or to revoke or deny the issuance or renewal of operating permits, and private parties may seek damages from us. Under such circumstances, we could be required to curtail or cease operations, conduct site remediation or other corrective action, or pay substantial damage claims for which may not have sufficient or any insurance coverage for claims.

If we fail to maintain an effective system of internal control over financial reporting, we may not be able to accurately report our financial results, and current and potential stockholders may lose confidence in our financial reporting.

Section 404 of the Sarbanes-Oxley Act of 2002 requires our management to assess the effectiveness of our internal control over financial reporting and to disclose in our filings if such controls were unable to provide assurance that a material error would be prevented or detected in a timely manner. We have an ongoing program to review the design of our internal controls framework in keeping with changes in business needs, implement necessary changes to our controls design and test the system and process controls necessary to comply with these requirements. If in the future, our internal controls over financial reporting are determined to be not effective resulting in a material weakness or significant deficiency, investor perceptions regarding the reliability of our financial statements may be adversely affected which could cause a decline in the market price of our stock and otherwise negatively affect our liquidity and financial condition.

We may have risks associated with security of our information technology systems.

We make significant efforts to maintain the security and integrity of our information technology systems and data. Despite significant efforts to create security barriers to such systems, it is virtually impossible for us to entirely mitigate this risk. There is a risk of industrial espionage, cyber-attacks, misuse or theft of information or assets, or damage to assets by people who may gain unauthorized access to our facilities, systems, or information. Such cybersecurity breaches, misuse, or other disruptions could lead to the disclosure of confidential information; improper usage and distribution of our intellectual property; theft, manipulation, and destruction of private and proprietary data; and production downtimes. Although we actively employ measures to prevent unauthorized access to our information systems, preventing unauthorized use or infringement of our rights is inherently difficult. These events could adversely affect our financial results and any legal action in connection with any such cybersecurity breach could be costly and time-consuming and may divert management’s attention and adversely affect the market’s perception of us and our products. In addition, we must frequently expand our internal information system to meet increasing demand in storage, computing and communication, which may result in increased costs. Our internal information system is expensive to expand and must be highly secure due to the sensitive nature of our customers’ information that we transmit. Building and managing the support necessary for our growth places significant demands on our management and resources. These demands may divert such resources from the continued growth of our business and implementation of our business strategy.

RISKS RELATED TO OUR COMMON STOCK

Future equity financings and issuances of shares under equity compensation plans would dilute your ownership and could adversely affect your common stock ownership rights in comparison with those of other security holders.

Our board of directors has the power to issue additional shares of common stock without stockholder approval. Additional shares are subject to issuance through various equity compensation plans or through the exercise of currently outstanding equity awards. Our stockholders do not have preemptive rights to any common stock issued by us in the future; therefore, stockholders may experience additional dilution of their equity investment if we issue additional shares of common stock in the future, including shares issuable under equity incentive plans, or if we issue securities that are convertible into shares of our common stock.

If additional funds are raised through the issuance of equity securities, the percentage of ownership of our existing stockholders will be reduced, and such newly issued securities may have rights, preferences or privileges senior to those of existing stockholders. If we issue additional common stock or securities convertible into common stock, such issuance will reduce the proportionate ownership and voting power of each other stockholder. In addition, such stock issuances might result in a reduction of the market value of our common stock, which could make our stock unattractive to existing stockholders.

Provisions in our articles of incorporation and bylaws could discourage changes in the composition of our board of directors which could hinder an acquisition of us by a third party, even if the acquisition would be favorable to you, thereby adversely affecting existing stockholders.

Our articles of incorporation and bylaws contain provisions that may have the effect of making more difficult or delaying attempts by others to obtain control of our board of directors and our Company, even when these attempts may be in the best interests of stockholders. For example, our articles of incorporation and bylaws provide for a classified board of directors which could delay or prevent changes in our control or management, including transactions in which stockholders might otherwise receive a premium for their shares over then-current market prices. These provisions may also limit the ability of stockholders to approve transactions that they may deem to be in their best interests.

There is limited trading volume of our common stock, which could make it difficult for you to liquidate an investment in our common stock in a timely manner.

Since August 27, 2021, our common stock has been traded on the Nasdaq Capital Market under the symbol SOTK. Because there is limited volume in our common stock, investors may not be able to liquidate their investments when they desire to do so.

In addition, if we fail to meet the criteria set forth in SEC and Nasdaq Capital Market rules and regulations, various requirements would be imposed by law on broker-dealers who sell our securities to persons other than established customers and accredited investors. Consequently, such regulations may deter broker-dealers from recommending or selling our common stock, which may further affect its liquidity.

If securities analysts do not publish research or reports about our business or if they downgrade us or our sector, the price of our common stock could decline.

The trading market for our common stock will depend in part on research and reports that industry or financial analysts publish about us or our business. Furthermore, if one or more of the analysts who cover us downgrades us, the industry in which we operate, or the stock of any of our competitors, the price of our common stock may decline. If one or more of these analysts ceases coverage altogether, we could lose visibility, which could also lead to a decline in the price of our common stock.

Our operating results can fluctuate significantly from period to period, which makes our operating results difficult to predict and can cause our operating results, in any particular period, to be less than comparable periods and expectations from time to time.

Our operating results have fluctuated significantly from quarter-to-quarter, period-to-period and year-to-year during our operating history and are likely to continue to fluctuate in the future due to a variety of factors, many of which are outside of our control. Certain factors that may affect our operating results include, without limitation, those set forth under “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Critical Accounting Policies” in this Annual Report on Form 10-K.

Because we have little or no control over many of these factors, our operating results are difficult to predict. Any adverse change in any of these factors could negatively affect our business and results of operations.

Our revenues, net income and other operating results are heavily dependent upon the size and timing of customer orders and projects, and the timing of the completion of those projects. The timing of our receipt of large individual orders, and of project completion, is difficult for us to predict. Because our operating expenses are based on anticipated revenues over the mid and long-term and because a high percentage of our operating expenses are relatively fixed, a shortfall or delay in recognizing revenues can cause our operating results to vary significantly from quarter-to-quarter and can result in significant operating losses or declines in profit margins in any particular quarter. If our revenues fall below our expectations in any particular quarter, we may not be able, or it may not be prudent for us, to reduce our expenses rapidly in

response to the revenue shortfall, which can result in us suffering significant operating losses or declines in profit margins in that quarter.

Due to these factors and the other risks discussed in this Annual Report on Form 10-K, you should not rely on quarter-to-quarter, period-to-period or year-to-year comparisons of our results of operations as an indication of our future performance. Quarterly, period and annual comparisons of our operating results are not necessarily meaningful or indicative of future performance. As a result, it is likely that, from time to time, our results of operations or our revenue backlog could fall below historical levels or the expectations of public market analysts and investors, which could cause the trading price of our common stock to decline significantly.

The market price of our common stock has been and may continue to be volatile.

The market price of our common stock has been volatile and fluctuates widely in response to various factors that are beyond our control. The price of our common stock is not necessarily indicative of our operating performance or long-term business prospects. In addition, the securities markets have from time-to-time experienced significant price and volume fluctuations that are unrelated to the operating performance of particular companies. These market fluctuations may also materially and adversely affect the market price of our common stock. Factors such as the following could cause the market price of our common stock to fluctuate substantially:

The realization of any of these risks and other factors beyond our control could cause the market price of our common stock to decline significantly. The stock market in general experiences, from time to time, extreme price and volume fluctuations. Periodic and/or continuous market fluctuations could result in extreme volatility in the price of our common stock, which could cause a decline in the value of our common stock. Price volatility may be worse if the trading volume of our common stock is low.

Future sales of our common stock, or the perception that future sales may occur, may cause the market price of our common stock to decline.

If any significant number of our outstanding shares are sold, such sales could have a depressive effect on the market price of our stock. We are unable to predict the effect, if any, that the sale of shares, or the availability of shares for future sale, will have on the market price of the shares prevailing from time to time. Sales of substantial numbers of shares in the public market, or the perception that such sales could occur, could depress prevailing market prices for the shares. Such sales may also make it more difficult for us to sell equity securities or equity-related securities in the future at a time and price that we deem appropriate.

Purchases under our Stock Repurchase Plan may cause the market price of our common stock to rise but may have an adverse effect on available cash.

In 2024, our Board approved the adoption of a Stock Repurchase Plan which permits us to make open market purchases of up to a total of $2,000,000 of our common stock from time-to-time at prices and in amounts we deem reasonable. Purchases under the Stock Repurchase Plan may cause the market price of our stock to rise, however, the amounts of such purchases are limited by federal securities regulations and by the parameters of the Stock Purchase Plan. To the extent that we use cash to make purchases under the Stock Repurchase Plan, such monies will not be available to fund our operations if ever needed. If adequate funds are not otherwise available, we may be required to delay or reduce the scope of our business plans.

The Company is considered a “smaller reporting company” and is exempt from certain disclosure requirements, which could make our common stock less attractive to potential investors.

Rule 12b-2 of the Securities Exchange Act of 1934 ("Exchange Act") defines a “smaller reporting company” as an issuer that is not an investment company, an asset-backed issuer, or a majority-owned subsidiary of a parent, that is not a smaller reporting company, and that had a public float of less than $250 million as of the last business day of its most recently completed second fiscal quarter, computed by multiplying the aggregate worldwide number of shares of its voting and non-voting common equity held by non-affiliates by the price at which the common equity was last sold, or the average of the bid and asked prices of common equity, in the principal market for the common equity.

As a “smaller reporting company,” we are subject to reduced disclosure requirements that are less comprehensive than applicable to issuers that are not “smaller reporting companies,” which could make our stock less attractive to potential investors and could make it more difficult for shareholders to sell their shares.

We have no current plan to pay dividends on our common stock, and investors may lose the entire amount of their investment.

 We have no current plans to pay dividends on our common stock; therefore, investors will not receive any funds absent a sale of their shares. We cannot assure investors of a positive return on their investment when they sell their shares, nor can we assure that investors will not lose the entire amount of their investment.

GENERAL RISK FACTORS

We will continue to incur significant costs as a result of operating as a public company, and our management may be required to devote substantial time to compliance initiatives that ultimately could have a material adverse effect on our financial condition and results of operations.

As a public company, we expect to continue to incur significant legal, accounting and other expenses. In addition, the Sarbanes-Oxley Act, as well as rules subsequently implemented by the SEC, have imposed various requirements on public companies, including requiring establishment and maintenance of effective disclosure and financial controls as well as mandating certain corporate governance practices. Our management and other personnel will continue to devote a substantial amount of time and financial resources to these compliance initiatives.

As a “smaller reporting company” we are able to take advantage of certain exceptions to disclosure requirements, including, but not limited to, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements and the exemption from providing a “Compensation Discussion and Analysis” section in our proxy statements; providing only two years of audited financial statements; and other “scaled” narrative business disclosure requirements that are less comprehensive than issuers that are not smaller reporting companies.

If we fail to staff our accounting and finance function adequately or maintain internal control systems adequate to meet the demands that are placed upon us as a public company, we may be unable to report our financial results accurately or in a timely manner and our business and stock price may suffer. The costs of being a public company, as well as diversion of management’s time and attention, may have a material adverse effect on our future business, financial condition and results of operations.

Changes in U.S. Generally Accepted Accounting Principles (“GAAP”) could adversely affect our financial results and may require significant changes to our internal accounting systems and processes.

We prepare our consolidated financial statements in conformity with GAAP. These principles are subject to interpretation by the Financial Accounting Standards Board (“FASB”), the SEC and various bodies formed to interpret and create appropriate accounting principles and guidance. The FASB periodically issues new accounting standards on a variety of topics. For information regarding new accounting standards, please refer to Note 1 and 2, “Business Description and Significant Accounting Policies,” of the Notes to Consolidated Financial Statements in Part II, Item 8, “Financial Statements and Supplementary Data,” of this Annual Report on Form 10-K. These and other such standards generally result in different accounting principles, which may significantly impact our reported results or could result in variability of our financial results.

In preparing our financial statements we make certain assumptions, judgments and estimates that affect amounts reported in our consolidated financial statements, which, if not accurate, may significantly impact our financial results.

We make assumptions, judgments and estimates for a number of items, including the fair value of financial instruments, long-lived assets and other intangible assets; the realizability of deferred tax assets; the recognition of revenue and the fair value of stock option awards; and others. We also make assumptions, judgments and estimates in determining the accruals for revenue recognition, product warranties, employee-related liabilities, including commissions and variable compensation, and in determining the allowance or provisions for uncertain tax positions, doubtful accounts, excess or obsolete inventory, and legal contingencies. These assumptions, judgments and estimates are drawn from historical experience and various other factors that we believe are reasonable under the circumstances as of the date of the consolidated financial statements. Actual results could differ materially from our estimates, and such differences could significantly impact our financial results.

Our business could be negatively affected as a result of actions of activist shareholders, and such activism could impact the trading value of our securities.

In recent years, shareholder activists have become involved in numerous public companies. Shareholder activists frequently propose to involve themselves in the governance, strategic direction and operations of the Company. Such proposals may disrupt our business and divert the attention of our Board of Directors, management and employees, and any perceived uncertainties as to our future direction resulting from such a situation could result in the loss of potential business opportunities, interfere with our ability to execute our strategic plan, be exploited by our competitors, cause concern to our current or potential customers, and make it more difficult to attract and retain qualified personnel and business partners, all of which could adversely affect our business. A proxy contest for the election of directors at our annual meeting could also require us to incur significant legal fees and proxy solicitation expenses. In addition, actions of activist shareholders may cause significant fluctuations in our stock price based on temporary or speculative market perceptions or other factors that do not necessarily reflect the underlying fundamentals and prospects of our business.

Major bank failure or sustained financial market illiquidity, or illiquidity at our clearing, cash management and custodial financial institutions, could adversely affect our business, financial condition and results of operations.

We face certain risks in the event of a sustained deterioration of financial market liquidity, as well as in the event of sustained deterioration in the liquidity, or failure, of our clearing, cash management and custodial financial institutions. In particular:

If financial liquidity deteriorates, there can be no assurance we will not experience an adverse effect, which may be material, on our ability to access capital and on our business, financial condition and results of operations.

Risk Management and Strategy

We own an industrial park located in Milton, New York. The industrial park consists of approximately 50,000 square feet of office and warehouse space. Our offices, product development, manufacturing and assembly facilities are located in the industrial park. We presently utilize 41,000 square feet or 82% of the park for our operations. We believe our facilities will be adequate for the foreseeable future and the ownership of the industrial park provides us opportunity to expand as we grow.

Approximately 9,000 square feet of the park is leased or available for lease to unrelated third parties at any given time.

PART II

Our common stock currently trades on the Nasdaq Capital Market.

As of May 18, 2026, there were 80 record holders of our common stock and approximately 2,321 beneficial shareholders of our Common Stock.

We have not paid any cash dividends on our Common Stock since inception. Except as set forth in the following table, we intend to retain earnings, if any, for use in our business and for other corporate purposes.

Forward-Looking Statements

We discuss expectations regarding our future performance, such as our business outlook, in our annual and quarterly reports, news releases, and other written and oral statements. These “forward-looking statements” are based on currently available competitive, financial and economic data and our operating plans. They are inherently uncertain, and investors must recognize that events could turn out to be significantly different from our expectations and could cause actual results to differ materially. These factors include, among other considerations, general economic and business conditions; political, regulatory, tax, competitive and technological developments affecting our operations or the demand for our products; inflationary and supply chain pressures; international hostilities, including war with Iran; the recovery of the Electronics/Microelectronics and Medical markets; maintenance of increased order backlog; the imposition of tariffs; timely development and market acceptance of new products and continued customer validation of our coating technologies; adequacy of financing; capacity additions, the ability to enforce patents; maintenance of operating leverage; consummation of order proposals; completion of large orders on schedule and on budget; continued sales growth in the medical and alternative energy markets; successful transition from primarily selling ultrasonic nozzles and components to a more complex business providing complete machine solutions and higher value subsystems; and realization of quarterly and annual revenues within the forecasted range of sales guidance.

We undertake no obligation to update any forward-looking statement.

Sono-Tek Corporation Fiscal Year 2026 Highlights (compared with fiscal 2025 unless otherwise noted)
We refer to the twelve-month periods ended February 28, 2026 and February 28, 2025 as fiscal 2026 and fiscal 2025, respectively.

Market and Geographic Diversity

We have invested significant resources to enhance our market diversity. By leveraging our core ultrasonic coating technology, we have expanded our portfolio of products, the industries we serve, and the countries in which we sell our products.

Today, we serve five industries: microelectronics/electronics, medical, alternative/clean energy, industrial markets, and emerging research and development and other.

We are a geographically diverse company with a presence either directly or through distributors and trade representatives in the United States and Canada, EMEA (Europe, Middle East and Africa), APAC (Asia Pacific) and Latin America (including Mexico). In fiscal 2026, approximately 33% of sales originated outside of the United States and Canada.

We have an established infrastructure of application process development laboratories located at our distributor sites in Japan, China, Germany, Singapore, South Korea and our home office in New York. These laboratories are equipped with Sono-Tek systems and technical personnel to conduct customer demonstrations and process development for new coating applications that our customers bring to us. Our engineering, service and sales teams all continue to grow as we expand our addressable markets and enhance our product line to include larger more sophisticated machinery and systems with increased capabilities.

We believe that the new products we have introduced, the new markets we have penetrated, and the expanded regions in which we now sell our products, are a strong foundation for our future sales growth and enhanced profitability.

Results of Operations

Sales and Gross Profit:

Gross profit increased $821,000, or 8% to $10,560,000 for fiscal 2026 compared with $9,739,000 in fiscal 2025. The gross profit percentage increased to 51% for fiscal 2026, compared to 48% for fiscal 2025.

In fiscal 2026 the increase in the gross profit percentage was influenced by product mix, including a favorable mix of mature high ASP systems with reduced manufacturing costs. In addition, sales to the United States were strong, which carry fewer distributor related expenses.

Product Sales:

Total sales for fiscal year 2026 increased by 2%, driven primarily by significant growth in Integrated Coating Systems and Fluxing Systems, partially offset by declines in Multi-Axis Coating Systems and other product categories.

In-Line Coating System sales increased by 91%, or $3,367,000, to $7,070,000 due to shipments of multiple high ASP production systems, including several systems delivered to a key customer in the solar energy market. This increase reflects continued success in transitioning customers from research and development systems to production-scale platforms.

Fluxing System sales increased 53%, or $246,000, to $713,000, primarily driven by increased demand in Asia.

Multi-Axis Coating System sales decreased by $2,623,000, or 25%, to $8,055,000, primarily due to reduced demand in electrolysis-related applications within the Alternative/Clean Energy market.

OEM System sales decreased 18%, or $274,000, to $1,210,000, and Other product sales declined 7%, or $311,000, to $3,861,000, reflecting normal variability in customer demand and order timing.

Overall, product mix in fiscal 2026 continued to shift toward higher-value, production-scale systems, consistent with the Company’s strategic focus on expanding its portfolio of complex, high-ASP coating solutions.

Market Sales:

Sales to the Medical market increased $1,754,000, or 54%, to $5,004,000 in fiscal 2026 compared to $3,250,000 in fiscal 2025. The increase was driven by strong demand for coating systems used in applications such as balloon catheter manufacturing, specialty stent coating needs, and custom medical device applications.

Electronics/Microelectronics sales increased $864,000, or 16%, to $6,290,000 in fiscal 2026 compared to $5,426,000 in fiscal 2025, reflecting continued demand for electrically active coatings for diagnostic-related applications.

Sales to the Alternative/Clean Energy market decreased $1,864,000, or 19%, to $7,974,000 in fiscal 2026 compared to $9,838,000 in fiscal 2025. The decrease was primarily attributable to reduced demand for electrolysis-related systems, influenced by reductions and eliminations of government incentives, partially offset by solar-related system shipments earlier in the fiscal year.

Industrial sales decreased $348,000, or 18%, to $1,575,000 in fiscal 2026 compared to $1,923,000 in fiscal 2025, reflecting continued variability in demand for industrial coating applications.

Emerging R&D and Other sales remained relatively unchanged and continue to represent an increasingly smaller portion of total revenue. As customer applications progress from development-stage activity to commercial adoption, the related revenue opportunity typically transitions into our larger addressable end markets, including Medical, Electronics/Microelectronics, Alternative/Clean Energy and Industrial.

Geographic Sales:

In fiscal 2026, approximately 67% of our sales were to US and Canadian customers. This is compared to 61% in fiscal 2025, reflecting a continued shift toward domestic, production-oriented customers and higher-value system shipments.

Sales in the United States and Canada increased $1,440,000, or 12%, to $13,946,000 in fiscal 2026 compared to $12,506,000 in fiscal 2025. This increase was driven by increased shipments of production systems with high ASPs, including significant system deliveries to a major solar customer, as well as a greater concentration of revenue from domestic customers where we benefit from lower distribution and logistical costs.

Sales in international markets declined, with Asia Pacific decreasing $128,000, or 5%, to $2,630,000, Europe, Middle East and Africa decreasing $689,000, or 16%, to $3,742,000, and Latin America decreasing $218,000, or 27%, to $591,000. These decreases reflect variability in regional demand and the timing of system shipments.

Operating Expenses:

Research and Product Development:

Research and product development costs decreased $170,000 to $2,554,000 for fiscal 2026 due to a decrease in salary associated with the departure of a senior engineer, a decrease in research and development materials, supplies, insurance expense and travel expenses. These decreases were partially offset by additional lab salaries.

Marketing and Selling:

Marketing and selling expenses decreased $153,000 to $3,525,000 for fiscal 2026 due to a decrease in salary expense, a decrease in travel and trade show expenses and a decrease in commission expense.

During fiscal 2026, we expended approximately $568,000 for travel and trade show expenses compared with $595,000 for the prior fiscal year, a decrease of $27,000. Our sales and marketing costs are variable, and a large portion of the costs are dependent upon trade shows and where geographically our sales are generated. We anticipate that our costs will increase in the future as we increase our trade show presence and the potential change in geographic origin of our sales from our in-house sales team to our external distributors.

In fiscal 2026, we expended approximately $635,000 for commissions as compared with $767,000 for the prior fiscal year, a decrease of $132,000. The decline was driven by a higher mix of sales closed directly by our in-house team. Our in-house team earns a consistent commission percentage on all sales. When sales are made through distributors or manufacturer representatives, we also incur their additional commissions (and related channel costs), which increase total selling costs. The shift toward direct sales reduced those third-party costs in the current period.

We expect our marketing and sales expenses to increase in fiscal 2027 as we invest in additional sales personnel, forward deployed engineering personnel, and programming talent to support new business opportunities, particularly those associated with production systems that have high ASPs to drive future growth.

General and Administrative:

General and Administrative (G&A) costs increased $329,000 to $2,656,000 for fiscal 2026 due to an increase in salaries, insurance expense, corporate expenses, stock-based compensation and other expenses. These increases were partially offset by a decrease in professional fees.

In fiscal 2026 stock-based compensation expense increased $69,000 to $317,000, compared with $248,000 in fiscal 2025. The increase in stock-based compensation expense in fiscal 2026 is due to option awards that were issued in the prior fiscal year. Option awards are expensed over three years based on vesting terms.

In the fourth quarter of fiscal 2024, we were notified by the State of California that we were required to collect sales tax on our shipments to customers in California. In connection with previous taxable sales, we collected approximately $86,000 of delinquent sales tax from our customers in fiscal 2025. As of February 29, 2024, on the basis of a preliminary analysis of our sales to our California customers commencing on April 1, 2019, we recorded an accrual in the amount of $138,000 for the estimated sales tax, penalties and interest that we may have been required to remit to the State of California.

In the second quarter of fiscal 2025, we filed all necessary sales tax returns with the State of California. Our net expense for sales tax and interest amounted to $72,000. In the second quarter of fiscal 2025, we reversed the remaining accrual of $66,000. This reversal is recorded in general and administrative expenses.

Operating Income:

Our operating income increased $815,000 or 81%, to $1,825,000 in fiscal 2026 compared with $1,010,000 for the prior fiscal year. Operating margin for fiscal 2026 increased to 9% compared with 5% in fiscal 2025. In fiscal 2026, the increase in gross profit was the key factor in the increase in operating income.

Interest and Dividend Income:

Interest and dividend income decreased $45,000 to $444,000 for fiscal 2026 as compared with $489,000 for the prior fiscal year, reflecting a minor reduction in interest rates earned on our cash balances in fiscal 2026. Our present investment policy is to invest excess cash in highly liquid, low risk US Treasury securities and certificates of deposit. At February 28, 2026, the majority of our holdings are rated at or above investment grade.

Income Tax Expense:

We recorded an income tax expense of $461,000 for fiscal 2026 compared with $261,000 for the prior fiscal year. The increase in income tax expense in fiscal 2026 is due to the current year’s increase in income before income taxes offset by the application of available research and development tax credits.

The deferred tax asset decreased approximately $384,000, to $1,142,000 at February 28, 2026 from $1,525,000 at February 28, 2025. Additionally, the deferred tax liability decreased approximately $76,000, to $56,000 at February 28, 2026 from $132,000 at February 28, 2025. The net decrease in the deferred tax asset and liability was approximately $307,000 for fiscal 2026. This decrease is primarily due to the retroactive expensing of research and development expenses that were capitalized for tax purposes, prior to the enactment of the One Big Beautiful Bill Act (the “Act” or “OBBBA”) on July 4, 2025.

The Act introduced significant changes to the Internal Revenue Code, including the permanent extension of many provisions of the 2017 Tax Cuts and Jobs Act (“TCJA”) and various new tax incentives and adjustments. The financial reporting implications of the Act were recorded in the income tax provision for fiscal 2026, in accordance with ASC 740, Income Taxes.

The OBBBA did not change the statutory U.S. federal tax rate. Accordingly, the OBBBA did not compel us to remeasure our deferred tax assets and liabilities solely because of a rate change. However, the various changes in tax law did impact our current and deferred tax calculations.

The most significant tax provisions impacting us include:

Bonus Depreciation – The Act permanently restores 100% bonus depreciation for qualified property acquired and placed into service after January 19, 2025.

Research and Development (“R&D”) Costs – The Act reinstates the ability for entities to immediately expense domestic R&D costs for tax years beginning after December 31, 2024. Certain small businesses may also retroactively expense R&D costs, which were capitalized under the TCJA during the calendar years 2022 – 2024.

In accordance with the Act, for the fiscal year ended February 28, 2026, the Company has expensed the R&D costs incurred for the current calendar year end. Pursuant to the Act, R&D costs amounts previously capitalized and recorded as a deferred tax asset now are eligible to be expensed in full verses being amortized periodically over a five year term.  Any prior year R&D amounts capitalized and not utilized in the current year will be carried over as a deferred tax asset. Some states have decoupled from the federal tax provisions of the Act and continue to follow the prior tax laws per the 2017 Tax Cuts and Jobs Act for capitalizing and amortizing R&D costs. The expensing of these costs is subject to taxable income limitations.

Net Income:

Net income increased $533,000 or 42%, to $1,806,000 for fiscal 2026 compared with $1,273,000 for the prior fiscal year. The increase in net income in fiscal 2026 is a result of an increase in gross profit offset by a slight increase in operating expenses and partially offset by an increase in income tax expense.

Liquidity and Capital Resources

Working Capital – Our working capital increased $2,735,000 to $16,236,000 at February 28, 2026 from $13,501,000 at February 28, 2025. The increase in working capital was primarily the result of the current year’s net income and non-cash charges partially offset by purchases of equipment and redemptions of the Company’s stock.

We aggregate cash and cash equivalents and marketable securities in managing our balance sheet and liquidity. For purposes of the following analysis, the total is referred to as “Cash.” At February 28, 2026 and February 28, 2025, our working capital included:

The following table summarizes the accounts and the major reasons for the $2,879,000 increase in “Cash”:

During fiscal 2026 the net increase in our marketable securities was $742,000. This increase is included in the net increase in cash in the table above.

Stockholders’ Equity – Stockholders’ Equity increased $1,982,000 from $17,792,000 at February 28, 2025 to $19,774,000 at February 28, 2026. The increase is a result of the current year’s net income of $1,806,000, proceeds from exercise of stock options of $11,000, and $317,000 in additional equity related to stock-based compensation awards. These increases were partially offset by treasury stock purchases of $151,000. The details of stock-based compensation awards are explained in Note 4 in our financial statements.

During fiscal 2025 and fiscal 2026, we acquired a total of 44,091 shares of our common stock pursuant to a Stock Repurchase Plan which terminated in January 2026. Such shares were held as treasury stock until February 2026 when they were canceled, becoming authorized but unissued.

Operating Activities – We generated $3,246,000 of cash in our operating activities in fiscal 2026 compared with generating $525,000 in fiscal 2025, an increase of $2,721,000. The increase in cash generated by operating activities was the result of increases in accounts payable, accrued expenses, an increase in customer deposits and a decrease in inventories. These sources of cash were partially offset by an increase in accounts receivable, an increase in prepaid expenses and an increase in income taxes payable.

In fiscal 2026, our accounts receivable increased $1,003,000 when compared to the prior year. The increase in accounts receivable is primarily due to a large number of sales occurring in the fourth quarter of fiscal 2026. 

In fiscal 2026, customer deposit balances increased $657,000 when compared to the prior year. The increase in customer deposits is primarily due to a large number of shipments occurring in the fourth quarter of fiscal 2026.

Investing Activities – In fiscal 2026, our investing activities used $968,000 of cash compared with providing $2,550,000 in fiscal 2025. Capital spending in fiscal 2026 was $225,000 for the purchase or manufacture of equipment, furnishings and leasehold improvements. This compares with $469,000 for the prior year period.

In fiscal 2026, we used $743,000 of cash for the purchase of marketable securities compared with $3,019,000 being generated in fiscal 2025.

Bank Credit Facilities:

We currently have a revolving credit line of $1,500,000 and a $750,000 equipment purchase facility, both of which are with a bank. The revolving credit line is collateralized by the Company’s accounts receivable and inventory. The revolving line of credit is payable on demand and must be retired for a 30-day period, once annually. As of February 28, 2026, there were no outstanding borrowings under the line of credit.

Backlog

At the end of fiscal year 2026, our total backlog amounted to $9,117,000, comprised of $8,968,000 in equipment backlog and $149,000 in services-related backlog.

Off - Balance Sheet Arrangements

We do not have any Off - Balance Sheet Arrangements as of February 28, 2026.

Critical Accounting Estimates

The discussion and analysis of the Company’s financial condition and results of operations are based upon the Company’s consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements requires the Company to make estimates and judgments that affect the reported amount of assets and liabilities, revenues and expenses, and related disclosure on contingent assets and liabilities at the date of the financial statements. Actual results may differ from these estimates under different assumptions and conditions.

Management’s estimates and judgements are continually evaluated and are based on historical experience and expectations regarding future events that are believed to be reasonable under the specific circumstances.

Critical accounting estimates are defined as those that are reflective of significant judgments and uncertainties and may potentially result in materially different results under different assumptions and conditions.

Accounting for Income Taxes

The Company accounts for income taxes under the asset and liability method. Under this method, deferred income taxes are recognized for the tax consequences of “temporary differences” by applying enacted statutory tax rates applicable to future years to differences between the financial statement carrying amounts and the tax basis of existing assets and liabilities. Based on management’s estimate, if it is more likely than not that some portion or all of a deferred tax asset will not be realized, a valuation allowance is recognized. Management evaluates the valuation allowance based on current estimates and historical experience. We use a recognition threshold and a measurement attribute for financial statement recognition and measurement tax positions taken or expected to be taken in a return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. As of February 28, 2026 and February 28, 2025, there were no uncertain tax provisions.

On July 4, 2025, the One Big Beautiful Bill Act (the “Act” or “OBBBA”) was signed into law. The Act introduces significant changes to the Internal Revenue Code, including the permanent extension of many provisions of the 2017 Tax Cuts and Jobs Act (“TCJA”) and various new tax incentives and adjustments. The financial reporting implications of the Act were recorded in the income tax provision for the quarter and year to date periods ended November 30, 2025, in accordance with ASC 740, Income Taxes.

The OBBBA did not change the statutory U.S. federal tax rate. Accordingly, the OBBBA did not compel the Company to remeasure its deferred tax assets and liabilities solely because of a rate change. However, the various changes in tax law did impact the Company’s current and deferred tax calculations.

The most significant tax provisions impacting the Company include:

Bonus Depreciation – The Act permanently restores 100% bonus depreciation for qualified property acquired and placed into service after January 19, 2025.

Research and Development Costs – The Act reinstates the ability for entities to immediately expense domestic research and development costs for tax years beginning after December 31, 2024. Certain small businesses may also retroactively expense research and development costs, which were capitalized under the TCJA during the calendar years 2022 – 2024.

In accordance with the Act, for the fiscal year ended February 28, 2026, the Company has expensed the R&D costs incurred for the current calendar year end. Pursuant to the Act, R&D costs amounts previously capitalized and recorded as a deferred tax asset now are eligible to be expensed in full verses being amortized periodically over a five year term. Any prior year R&D amounts capitalized and not utilized in the current year will be carried over as a deferred tax asset. Some states have decoupled from the federal tax provisions of the Act and continue to follow the prior tax laws per the 2017 Tax Cuts and Jobs Act for capitalizing and amortizing R&D costs. The expensing of these costs is subject to taxable income limitations.

Revenue Recognition

The Company recognizes revenue in accordance with ASC 606, Revenue from Contracts with Customers, the core principle of which is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to receive in exchange for those goods or services.

Judgement is required when determining at what point in time control of the Company’s manufactured equipment is transferred to its customers. Management’s judgement is based on each customer contract and the transfer of control of the equipment to the customer. The sales revenue to be recorded is based on each contract. 

Impact of New Accounting Pronouncements

In November 2024, the FASB issued ASU 2024-03 – Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which is intended to provide more detailed information about specified about specified categories of expenses (purchases of inventory, employee compensation, depreciation and amortization) included in certain expense captions presented on the consolidated statement of operations. The guidance in this ASU is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the impact the adoption of this ASU will have on its consolidated financial statements and related disclosures.

Other than ASU 2023-09 discussed above, accounting pronouncements issued but not yet effective have been deemed to be not applicable or the adoption of such accounting pronouncements is not expected to have a material impact on the financial statements of the Company.

Our financial statements are presented on pages F-1 to F-17 of this Report.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the “Act”)) as of the end of the period covered by this annual report on Form 10-K.  Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that these disclosure controls and procedures were effective as of such date, at a reasonable level of assurance, in ensuring that the information required to be disclosed by us in the reports we file or submit under the Act is (i) accumulated and communicated to our management (including the Chief Executive Officer and Chief Financial Officer) in a timely manner, and (ii) recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

Internal Control Over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f). Under the supervision and with the participation of our management, including our Chief Executive Officer (principal executive officer) and Chief Financial Officer (principal accounting officer), we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the criteria in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on our evaluation, management has concluded that our internal control over financial reporting was effective as of and for the year ended February 28, 2026. 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 risks that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Changes in Internal Control Over Financial Reporting

There was no change in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934, as amended) that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors of

Sono-Tek Corporation:

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Sono-Tek Corporation (the “Company”) as of February 28, 2026 and 2025, the related consolidated statements of income, stockholders’ equity and cash flows for the years ended February 28, 2026 and 2025, and the related notes (collectively referred to as the “financial statements”). In our opinion, based on our audits, the financial statements present fairly, in all material respects, the financial position of the Company as of February 28, 2026 and 2025, and the results of its operations and its cash flows for the years ended February 28, 2026 and 2025, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (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 financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the 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 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 financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

Critical audit matters are matters arising from the current period audit of the 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 financial statements and (2) involved our especially challenging, subjective, or complex judgments. We determined that there are no critical audit matters.
