CAUTIONARY STATEMENT FOR FORWARD LOOKING STATEMENTS

Certain statements in this report, other than purely historical information, are "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). These forward-looking statements generally are identified by the words "believe," "aim," "projected," "expect," "anticipate," "estimate," "forecast," "outlook," "intend," "scheduled," "targets," "strategy," "future," "opportunity," "plan," "may," "should," "will," "would," "will be," "will continue," "will likely result," or the negative thereof or variations thereon or similar expressions generally intended to identify forward-looking statements.

These statements are based on currently available information and our current assumptions, expectations and projections about future events. While we believe that our assumptions, expectations and projections are reasonable in view of the currently available information, you are cautioned not to place undue reliance on our forward-looking statements. Forward-looking statements speak only as of the date they are made and are not guarantees of future performance. They are subject to future events, risks and uncertainties – many of which are beyond our control – as well as potentially inaccurate assumptions, that could cause actual results to differ materially from our expectations and projections including, among other things:

•global macroeconomic factors;

•increased prices and inflationary pressures;

•volatility and uncertainty in the political, economic and regulatory environments in which we operate, including new or increased tariffs, changes to trade agreements, sanctions, import and export regulations, custom duties and applicable tax regulations and interpretations, social and political unrest, instability, national and international conflict, terrorist acts and other geographical disputes and uncertainties;

•the strength and stability of the institutional, commercial and residential construction and remodeling markets;

PART I

Item 1. BUSINESS

Overview

Allegion plc ("Allegion," "we," "us" or "the Company") is a leading global provider of security products and solutions that keep people and assets safe and secure in the places they live, learn, work and connect. We pioneer safety and security to create a safer and more accessible world. Both developing and partnering are central to our work to create ecosystems that enable seamless access experiences and an uninterrupted and secure flow of people and assets. We offer an extensive and versatile portfolio of security and access control products and solutions across a range of market-leading brands. Our experts around the world deliver high-quality hardware, software, services and systems, and we use our deep expertise to serve as trusted partners to end-users who seek customized solutions to their security needs.

We offer the following extensive and versatile portfolio of security and access control products and solutions across a range of market-leading brands:

•Door controls, door control systems, and exit devices: An extensive portfolio of life-safety products and solutions generally installed on fire doors and facility entrances and exits. Exit devices, also known as panic hardware, provide rapid egress to allow building occupants to exit safely in an emergency. Door controls and systems include mechanical door closers, automatic door operators, as well as high-performance interior and storefront door systems. In addition, we offer a full range of automatic entrance solutions, including sliding, swing, folding and ICU doors, as well as an array of sensors, controls and security options for commercial and institutional buildings. Sold under leading brands like Briton®, CISA®, LCN®, STANLEY® Access Technologies ("Stanley Access Technologies" or "Stanley"; "STANLEY" is the property of Stanley Logistics L.L.C.) and Von Duprin®;

•Doors, glass and door systems, and accessories: A portfolio of hollow metal doors and frames, glass and specialty door systems, as well as a variety of additional security products and components, including hinges, door pulls, door stops, louvers, weather stripping, thresholds and other accessories. Sold under leading brands like Falcon®, Glynn-Johnson®, Ives®, Republic™, Steelcraft®, TGP® and Trimco®;

Additionally, we offer software as a service ("SaaS") offerings throughout the U.S. and internationally, including access control, platform integration and workforce management solutions through brands like Interflex, Yonomi® and Zentra® among others.

Security and access control products and solutions are critical elements in every building and home. Many door openings are configured to maximize a room’s particular form and function while also meeting local and national building and safety code requirements and end-user security needs. Most buildings have multiple door openings, each serving its own purpose and requiring different specific access control solutions. Each door must fit exactly within its frame, be prepared precisely for its hinges, synchronize with its specific lockset and corresponding latch and align with a specific key to secure the door. Moreover, with the growing adoption of connected hardware and software solutions, security products – including credentials – are increasingly linked electronically, integrated into access control software and popular consumer technology platforms and controlled with mobile applications, creating additional functionality and complexity.

We believe our ability to deliver a wide range of solutions that can be custom configured to meet end-users’ security needs is a key driver of our success. We accomplish this with:

•Our innovative, market-leading brands, many of which are known as pioneers in safety and / or invented their product categories, including: CISA, Interflex, LCN, Schlage, SimonsVoss and Von Duprin;

•Our extensive and versatile product and service portfolio, combined with our deep expertise, which enable us to deliver the right products and solutions to meet diverse security and functional specifications and to successfully and securely integrate into leading technologies and systems;

•Our consultative approach and expertise, which enable us to develop the most efficient and appropriate building security and access control specifications to fulfill the unique needs of our end-users and their partners, including architects, designers, security consultants, contractors, homebuilders and engineers;

Table of Contents

•Our access to and management of key channels in the market, which is critical to delivering our products in an efficient and consistent manner; and

•Our enterprise excellence capabilities, including our global manufacturing operations and agile supply chain, which facilitate our ability to deliver specific product and system configurations to end-users and consumers worldwide, quickly and efficiently.

We believe the security products industry will continue to benefit from several global macroeconomic trends, including:

•Expected growth in global electronic and electromechanical products and solutions as end-users adopt newer technologies in their facilities and homes;

•Heightened awareness of security and privacy requirements;

•Increased focus and adoption of mobile technology; and

•The shift to digital, interconnected and increasingly interoperable environments that require a strong ecosystem of partners.

We sell a wide range of security and access control solutions for end-users in commercial, institutional and residential facilities worldwide, including education, healthcare, government, hospitality, retail, commercial office and single and multi-family residential markets. Our portfolio spans more than 40 brands, including brands like CISA, Interflex, LCN, Schlage, SimonsVoss, and Von Duprin.

During the year ended December 31, 2025, we generated Net revenues of $4,067.3 million and Operating income of $859.5 million. The following table presents percentage of Net revenues by category.

History and Developments

We were incorporated in Ireland on May 9, 2013, to hold the commercial and residential security businesses of what was then Ingersoll Rand plc ("Ingersoll Rand"). On December 1, 2013, we became a stand-alone public company after Ingersoll Rand completed the separation of these businesses from the rest of Ingersoll Rand via the transfer of these businesses from Ingersoll Rand to us and the issuance by us of ordinary shares directly to Ingersoll Rand’s shareholders. Our security businesses have long and distinguished operating histories. Several of our brands were established more than 100 years ago, and many originally created their categories:

•Von Duprin, established in 1908, was awarded the first exit device patent;

•Schlage, established in 1920, was awarded the first patents granted for the cylindrical lock and the push button lock;

Table of Contents

•LCN, established in 1926, created the first door closer;

•CISA, established in 1926, devised the first electronically controlled lock;

•SimonsVoss, established in 1995, created the first keyless digital transponder; and

•Stanley Access Technologies patented the world's first hands-free door operator in 1931.

We have built upon these founding legacies since our entry into the security products market through the acquisition of Schlage, Von Duprin and LCN. Today, we continue to develop, acquire and introduce innovative products.

In 2018, we announced the formation of Allegion Ventures to invest in and help accelerate the growth of companies that have innovative, digital-first technologies and products such as touchless access and workspace monitoring solutions that complement our core business solutions. Building on this success, in December 2021, Allegion Ventures announced a second fund with an additional allocation of $100 million to focus on investing in technologies like artificial intelligence, video monitoring, machine learning and cybersecurity.

Recent examples of successful product launches by Allegion are illustrated in the table below:

Industry and Competition

We serve customers within institutional, commercial and residential construction and remodeling markets throughout North America, Europe, Asia and Oceania. We expect the security products industry will continue to benefit from favorable trends such as increased concerns about safety and security, and technology-driven innovation that enables seamless access and a better user experience as people and assets traverse multiple locations and facilities. Further, we expect continued growth in connected security products and solutions as end-users continue to adopt newer technologies, including mobile solutions and artificial intelligence, in their facilities and single and multi-family homes.

The security products markets are highly competitive and fragmented throughout the world, with a number of large multi-national companies and thousands of smaller regional and local companies. This high degree of fragmentation primarily reflects local regulatory requirements and highly variable end-user needs. We believe our principal global competitors are Assa Abloy AB and dormakaba Group. We also face competition in various markets and product categories throughout the world, including Fortune Brands Innovations, Inc. in the North American residential market and from private label brands. As we move into more technologically advanced product categories, we may also compete against new, more specialized competitors.

Our success depends on a variety of factors, including brand and reputation, knowledge and expertise in our industry, product breadth, innovation, integration with popular technology platforms, quality and delivery capabilities, price and service capabilities. As many of our businesses sell through distribution, our success also depends on building and partnering with a strong channel network. We compete based on the breadth, innovation and quality of our products and solutions, pricing, our ability to custom-configure solutions to meet individual end-user requirements and our global supply chain.

Customers

We sell most of our products and solutions through distribution and retail channels, including specialty distribution, e-commerce and wholesalers. We have built a network of channel partners that help our customers choose the right solution to meet their security needs and help commercial and institutional end-users fulfill and install orders. We also sell through a variety of retail channels, including large do-it-yourself home improvement centers, multiple online and e-commerce platforms, as well as small, specialty showroom outlets. We work with our retail partners on developing marketing and merchandising strategies to maximize their sales per square foot of shelf space. Through a few of our businesses, most notably Stanley Access Technologies, Interflex and our Global Portable Security brands, we also provide products and services directly to end-users.

Our 10 largest customers represented approximately 26% of our total Net revenues in 2025. No single customer represented 10% or more of our total Net revenues in 2025.

Sales and Marketing

In markets where we sell through commercial and institutional distribution channels, we employ sales professionals around the world who work with a combination of end-users, security professionals, architects, contractors, engineers and distribution partners to develop specific, custom-configured solutions to meet our end-users’ needs. Our field sales professionals are assisted by specification writers who work with architects, engineers and consultants to help design door openings and security systems to meet end-users’ functional, aesthetic and regulatory requirements. Both groups are supported by dedicated customer care and technical sales support specialists worldwide. We also support our sales efforts with a variety of marketing efforts, including trade-specific advertising, cooperative distributor merchandising, digital marketing and marketing at a variety of industry trade shows.

In markets where we sell through retail and homebuilder distribution channels, we have teams of sales, merchandising and marketing professionals who help drive brand and product awareness through our channel partners and to consumers. We utilize a variety of advertising and marketing strategies, including traditional consumer media, retail merchandising, digital marketing, retail promotions and builder and consumer trade shows, to support these teams.

We also work actively with several industry bodies around the world to help promote effective and consistent safety and security open platform standards. For example, we are members of the American Association of Automatic Door Manufacturers (AAADM), American Institute of Architects (AIA), Builders Hardware Manufacturers Association (BHMA), Connectivity Standards Alliance (CSA), Door Security and Safety Foundation (DSSF), Construction Specification Institute, Door and Hardware Institute (DHI), FiRa Consortium, National Association of State Fire Marshals (NASFM), Partner Alliance for Safer Schools (PASS), Physical Security Interoperability Alliance (PSIA), Security Industry Association (SIA), Security Technology Alliance, Z-Wave Alliance, The European Federation of Associations of Locks and Builders Hardware Manufacturers (ARGE), ASSOFERMA (Italy), BHE (Germany), Door Hardware Federation (UK), Open Security Standards Association (Germany) and UNIQ (France).

Production and Distribution

We manufacture products in several geographic markets around the world. We operate 37 principal production and assembly facilities – 22 in our Allegion Americas segment and 15 in our Allegion International segment. Our strategy is to produce in the region of use, wherever appropriate, to allow us to be closer to the end-user and increase efficiency and timely product delivery. Much of our U.S. based residential portfolio is manufactured in the Baja region of Mexico under the Maquiladora,

Table of Contents

Manufacturing and Export Services Industry ("IMMEX") program. In managing our network of production and assembly facilities, we focus on continuous improvement in customer experience, employee health and safety, productivity, resource utilization and operational excellence.

We distribute our products through a broad network of channel partners. In addition, third-party manufacturing and logistics providers perform certain manufacturing, storage and distribution services for us to support certain parts of our manufacturing and distribution network.

Raw Materials

We continue to support our region-of-use production strategy with corresponding region-of-use supplier partners for much of our supply base. Our global and regional commodity teams work with production leadership, product management and materials management teams to source materials for production. Where appropriate, we may enter fixed-cost contracts to lower overall costs.

We purchase a wide range of raw materials, including steel, zinc, brass and other non-ferrous metals, as well as other parts and components, such as electronic components, to support our production facilities.

Intellectual Property

Intellectual property, inclusive of certain patents, trademarks, copyrights, know-how, trade secrets and other proprietary rights, is important to our business. We create, protect and enforce our intellectual property investments in a variety of ways. We work actively in the U.S. and internationally to help ensure the protection and enforcement of our intellectual property rights. We use trademarks on nearly all our products and believe such distinctive marks are an important factor in creating a market for our goods, in identifying us and in distinguishing our products from others. We consider our CISA, Interflex, LCN, Schlage, SimonsVoss, Von Duprin and other associated trademarks to be among our most valuable assets, and we have registered these trademarks in a number of countries. Although certain proprietary intellectual property rights are important to our success, we do not believe we are materially dependent on any particular patent or license, or any particular group of patents or licenses.

Research and Development

Our research and development ("R&D") efforts focus on advancing innovative products and solutions designed to drive growth and enhance competitiveness. Key areas of emphasis include the development of new product platforms as well as initiatives aimed at improving product cost efficiency, quality, safety and sustainability.

R&D resources are managed globally to leverage technologies and product platforms across our business units, while optimizing development costs and resource utilization. Regional teams apply their expertise in local standards and configurations to adapt products to specific market requirements, thereby enhancing customer value. Additionally, we operate a global technology center in Bengaluru, India, which provides engineering support and augments the capabilities of our regional R&D teams.

Seasonality

Our business experiences seasonality that varies by product and service line. For instance, as more construction and do-it-yourself projects occur during the second and third calendar quarters in the Northern Hemisphere, our security product sales related to those projects are typically higher in those quarters than in the first and fourth quarters. However, certain other businesses typically experience higher sales in the fourth quarter, due to demand for services and project timing.

Human Capital

Our human capital strategy is based on our values and is foundational to achieving our business strategy. Our workplace culture is based on practices that reward performance, provide growth and development opportunities, and support employees with competitive compensation and benefits packages. As a testament to this, Allegion received the Gallup Exceptional Workplace Award in both 2024 and 2025. This award recognizes the most engaged workplace cultures in the world.

As of December 31, 2025, we had approximately 13,300 employees worldwide. Our employee base is supplemented by contingent labor where business demand fluctuates or we experience short-term needs for specialized skills. Approximately 45% of employees are employed within the U.S. and approximately 55% based outside the U.S. Among our U.S. based employees, approximately 16% were subject to collective bargaining agreements with various labor unions. Outside the U.S., we have employees in certain countries, particularly in Europe, that are represented by an employee representative organization, such as a works council. We believe our relations with our workforce in both unionized and non-unionized settings are generally positive.

Talent Attraction and Retention

Our employer brand creates a differentiated employee experience intended to attract and retain the right talent for Allegion. Our talent attraction efforts are focused on and highlight a culture that reflects our core values, Allegion leadership behaviors and business objectives.

Table of Contents

We want to attract talent with core capabilities relevant to our long-term corporate business strategy: customer focus, innovation, partnering, pace and agility and collaboration. We use a variety of recruitment tactics to help ensure a strong base of labor for manufacturing operations and to build the base of talent with these capabilities. Throughout the recruitment cycle, we provide a technology-enabled seamless experience for internal and external candidates and hiring managers. Our compensation and benefit programs are designed to be competitive in the geographies where we work, including a total rewards package (which varies by country/region) that includes hourly and salaried compensation, performance-based incentive and long-term equity incentive plans, retirement, insurance and government social welfare programs, disability and family leave, health and wellness programs, education benefits to pursue degrees and certifications and additional offerings to support financial stability and personal planning.

Talent Development and Succession Planning

Talent development and succession planning are key components of the Allegion Operating System, which supports governance, reporting processes and management of the business. Our performance management system includes annual performance reviews for all permanent salaried employees. Talent development and succession planning takes place at all levels of the organization and is supported through individual career mapping, assessment of performance and talent pipeline planning up to and including the executive leadership team ("ELT"). As part of their quarterly business review, the ELT reviews talent development, focusing on developing a diverse succession pipeline. These cross-functional reviews highlight individuals who are ready for new opportunities, individuals who are on a special assignment or project and individuals early in their career that demonstrate emerging leadership skills.

Learning and Development

Opportunities for ongoing learning and development are delivered to employees through structured coursework, on-site and expert-led training and experiential, applied development. The Allegion Academy is offered globally, supporting multiple languages and providing thousands of self-guided online courses. We offer programs to provide successive levels of development, including re-skilling and upskilling existing employees, as well as strengths-based leadership curriculum and global programs for employee mentoring and coaching.

Culture and Engagement

Culture and engagement are also parts of the Allegion Operating System. Engagement surveys provide a mechanism to gather direct employee feedback, give team leaders insights on potential areas of focus, and allow leaders to prioritize and act on their teams’ foundational, inclusion, growth and development needs. Strengths-based leadership is an element of our commitment to inclusion: the more employees understand their own strengths, the better equipped they are to add value and appreciate the contributions of team members.

We believe in fundamental standards that support our employees, while building and maintaining diverse and inclusive workplaces. Employee-led resource and affinity groups provide opportunities for a variety of members of our workforce.

Employee Health and Safety

Employee health and safety are top priorities and integral to the Company's growth strategy. ‘Be safe, be healthy’ is a core organizational value in our proactive safety culture.

The ELT, with oversight from our Board of Directors, is responsible for risk management, employee accountability, safety hazard recognition and executing safety initiatives. We monitor leading and lagging indicators related to health and safety as part of our ongoing management of the Allegion Operating System and we regularly update the Corporate Governance and Nominating Committee of the Board of Directors on key developments and employee health and safety topics.

Regulatory Matters

We are subject to a variety of federal, state and local laws and regulations, both within and outside the U.S., relating to Environmental, Health and Safety ("EHS") matters. We are committed to conducting business in a safe, environmentally responsible and sustainable manner, in compliance with all applicable EHS laws and regulations, as well as some applicable voluntary programs and collective agreements. We continuously work to promote and protect the health and safety of the environment, employees, customers, contractors and members of our local communities worldwide. We operate with principles and practices that support our commitments. These include:

•Integrating sound EHS and sustainability strategies in all elements of our business, we set quantitative metrics and targets to provide clear accountability and to monitor and measure improvement in EHS performance;

•Conducting periodic, formal evaluations and audits of our compliance status, while also routinely reviewing our objectives and metrics;

•Fostering a workplace culture where everyone at Allegion is responsible for safety:

•Implementing measures to enhance internal and external stakeholder awareness of our environmental management policy and its impacts;

Table of Contents

•Establishing prioritization and action plans to continuously improve our EHS and sustainability management systems and performance; this includes reduction in use of natural resources, minimization of waste and prevention of pollution, as well as prevention and elimination of workplace accidents, injuries and risks;

•Designing, operating and maintaining our facilities in a manner that minimizes negative EHS and sustainability impacts;

•Using materials responsibly, including, where feasible, the recycling and reuse of materials; and

•Acting in a way that shows sensitivity to community concerns about EHS and sustainability issues.

We recognize these principles are critical to our future success. We are currently engaged in site investigations and remediation activities to address environmental cleanup from past operations at current and former production facilities. We also regularly evaluate our remediation methods that are in addition to, or in replacement of, those we currently utilize based upon enhanced technology and regulatory changes. We are sometimes a party to environmental lawsuits and claims and have, from time to time, received notices of potential violations of environmental laws and regulations from the U.S. Environmental Protection Agency ("EPA") and similar state authorities. We have also been identified as a potentially responsible party ("PRP") for cleanup costs associated with off-site waste disposal at federal Superfund and state remediation sites. For all such sites, there are other PRPs, and we believe our involvement is minimal.

In estimating our liability, we have assumed that we will not bear the entire cost of remediation of any site to the exclusion of other PRPs who may be jointly and severally liable. The ability of other PRPs to participate has been taken into account, based on our understanding of the parties’ financial condition and probable contributions on a per site basis. Additional lawsuits and claims involving environmental matters are likely to arise from time to time in the future. For a further discussion of our potential environmental liabilities, see Notes 2 and 19 to the Consolidated Financial Statements.

Environmental, social and governance ("ESG") factors important to our business are embedded into our values and our leadership's commitment to create a workplace culture grounded in doing the right thing in the right way. Our Board of Directors oversees the Company's ESG strategies, goals and performance, and both our leadership and employees all have a responsibility to uphold excellence, as we believe our commitment to ESG matters helps advance engagement and business vitality. Additional information about our ESG priorities and progress may be found in the ESG section of our website (found under the ESG tab at www.allegion.com). The website highlights our ongoing progress and advancements in ESG matters.

Item 1A. RISK FACTORS

We are subject to future events, risks and uncertainties – many of which are beyond our control – that could materially and adversely affect our business, financial condition, results of operations and cash flows. You should carefully consider the risk factors discussed below, together with all the other information included in this Form 10-K, in evaluating us and our securities. If any of the events, risks or uncertainties below actually occurs, our business, financial condition, results of operations and cash flows could be materially and adversely affected. Any such adverse effect may cause the trading price of our securities to decline, and as a result, you could lose all or part of your investment in us. Our business, financial condition, results of operations and cash flows may also be materially and adversely affected by events, risks and uncertainties not known to us or events, risks and uncertainties that we currently believe to be immaterial.

Economic, Market and Financial Risks

Our business performance is impacted by the strength of the institutional, commercial and residential construction and remodeling markets and global macroeconomic factors.

Demand for our security products and solutions relies on the institutional, commercial, and residential construction and remodeling markets, which are marked by cyclicality based on national, regional and local economic conditions, including consumer confidence and disposable income, corporate and government spending, work-from-home trends, availability of credit and demand for new housing and infrastructure. As a result, weakness or instability in one or more of these markets could

Table of Contents

slow demand for new construction or remodeling projects and cause current and potential customers to delay or cancel capital projects or otherwise choose not to make purchases, which could negatively impact the demand for our products and solutions and result in declines in our revenues, profitability and cash flows. In the recent past, our business operations and performance were also impacted by global macroeconomic challenges, including supply chain disruptions and delays, material, electronic component and labor shortages, prolonged periods of cost inflation, and increased interest rates. Negative macroeconomic trends, future market disruptions or uncertainty related to potential changes to fiscal and monetary policy and/or trade policy, including the imposition, or threatened imposition, of tariffs and potential retaliatory trade restrictions, may make it more challenging for us to manufacture and deliver products to our customers, could cause periodic production interruptions and supply constraints, impact our ability to forecast and plan for future business activities and, if not adequately managed by us, could cause a material adverse impact on our business, results of operations, financial condition and cash flows.

Increased prices, whether due to inflationary pressures or other factors, could negatively impact our margin performance and our financial results.

Higher prices for raw materials, parts and components, freight, packaging, labor and energy, whether caused by inflationary pressures or other geopolitical factors, such as new or increased tariffs, duties, or other charges as a result of changes to U.S. or international trade policies or trade agreements, increase our costs to manufacture and distribute our products and services, and we may be unable to pass these increased costs on to our customers. We do not currently use financial derivatives to hedge against volatility in commodity prices; however, we utilize firm purchase commitments, where possible, to help mitigate risk. The pricing of some materials, parts and components we use is based on market prices. To mitigate this exposure, we may use annual price contracts to minimize the impact of inflation and to benefit from deflation. However, these hedging and pricing strategies may not fully protect us against cost increases caused by factors such as new or increased tariffs, changing import duties, market illiquidity and specific local regulations.

Additionally, we are exposed to fluctuations in other costs such as packaging, freight, labor and energy prices. If these costs increase beyond our ability to control for them through measures such as implementing operating efficiencies, or we are not able to increase prices to sufficiently offset the effect of various cost increases without negatively impacting customer demand, our margin performance and results of operations would be negatively impacted.

Our global operations subject us to political, economic and regulatory risks, including uncertainty related to the imposition of new or increased tariffs and the global trade environment more generally.

Our businesses operate around the world in various geographic regions and product markets. Additionally, we procure various products, parts, components and services from supplier partners located throughout the world. Our global operations depend on products manufactured, purchased and sold in the U.S. and internationally, including in Australia, Canada, China, Europe, Mexico, New Zealand and the Middle East. The political, economic and regulatory environments in which we operate are becoming increasingly volatile and uncertain. Accordingly, we are subject to multiple risks that are inherent in operating and sourcing globally, including:

•Changes to trade agreements, foreign trade policies, sanctions, import and export regulations, including the imposition or threatened imposition of new or increased tariffs, quotas, customs duties and similar restrictions, as well as retaliatory actions that may be imposed by other governments in response to such tariffs or other trade restrictions;

•Changes in applicable tax regulations and interpretations;

•Economic downturns;

•Social and political unrest, instability, national and international conflict, including the conflicts in the Middle East and the war between Russia and Ukraine, border closures, civil disturbances, terrorist acts and other geographical disputes and uncertainties;

•Government measures to restrict business activity, for example, to prevent the spread of a communicable disease;

•Changes in laws and regulations or imposition of currency restrictions and other restraints in various jurisdictions;

•Limitation of ownership rights, including expropriation of assets by a local government, and limitation on the ability to repatriate earnings;

•Sovereign debt crises and currency instability in developed and developing countries;

•Difficulty in staffing and managing global operations;

•Difficulty in enforcing agreements, collecting receivables and protecting assets through non-U.S. legal systems; and

•Difficulty in transporting materials, components and products.

These risks have increased our cost of doing business in the U.S. and internationally. These risks may also increase our counterparty risk, disrupt our operations, disrupt the ability of suppliers and customers to fulfill their obligations, increase our effective tax rate, increase the cost of our products, limit our ability to sell products and services in certain markets, reduce our operating margin and cash flows and/or negatively impact our ability to compete.

Throughout 2025, the U.S. government announced tariffs on imports from several countries from which we manufacture and/or import products and components. In 2025, we have offset inflation due to tariffs with pricing actions. We estimate we source approximately 20-25% of Cost of goods sold from Mexico and less than 5% of Cost of goods sold from China. The degree to

Table of Contents

which any new or increased tariffs would impact our business and results of operations is largely dependent on factors outside of our control, including the timing, duration and magnitude of their implementation, and responses or retaliatory actions taken by other countries or regions. We can give no assurance that the impact of any tariffs will not have a material adverse effect upon our results of operations, financial condition or liquidity or that actions we may take to mitigate the impact of the tariffs will be effective.

Currency exchange rate fluctuations have had, and may continue to have, an adverse effect on our business, financial condition, results of operations and cash flows.

We are exposed to a variety of market risks, including the effects of changes in currency exchange rates. See "Part II, Item 7A. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Quantitative and Qualitative Disclosures About Market Risk."

Approximately 25% of our 2025 Net revenues were derived outside the U.S., and we expect sales to non-U.S. customers to continue to represent a significant portion of our consolidated Net revenues. Although we may enter into currency exchange contracts to reduce our risk related to currency exchange fluctuations, changes in the relative fair values of currencies occur from time to time and in some instances have had a significant impact on our results of operations. We do not hedge against all our currency exposure, and therefore, our results of operations will continue to be susceptible to impacts from currency fluctuations.

We also translate assets, liabilities, revenues and expenses denominated in non-U.S. dollar currencies into U.S. dollars for our Consolidated Financial Statements based on applicable exchange rates. Consequently, fluctuations in the value of the U.S. dollar compared to other currencies may have a material impact on the value of these items in our Consolidated Financial Statements, even if their value has not changed in their original currency. Further, certain of our businesses may invoice customers in a currency other than its functional currency, or may be invoiced by suppliers in a currency other than its functional currency, which could result in unfavorable translation effects on these businesses and our results of operations.

We may be required to recognize impairment charges for our goodwill, indefinite-lived intangible assets and other long-lived assets.

At December 31, 2025, the net carrying value of our goodwill and other indefinite-lived intangible assets totaled approximately $1.9 billion and $107.2 million, respectively. Pursuant to U.S. generally accepted accounting principles ("GAAP"), we are required to annually assess our goodwill and indefinite-lived intangible assets for impairment. In addition, interim assessments must be performed for these and other long-lived assets whenever events or changes in circumstances indicate that an impairment may have occurred. Significant disruptions to our business or end market conditions, protracted economic weakness (including a potential economic downturn or recession), unexpected significant declines in operating results of reporting units, divestitures or market capitalization declines may result in recognition of impairment charges to our goodwill, indefinite-lived intangible or other long-lived assets. Any charges relating to such impairments could have a material adverse impact on our results of operations in the periods when recognized.

The capital and credit markets are important to our business.

Future instability in U.S. and global capital and credit markets, including market disruptions, limited liquidity and interest rate volatility or reductions in the credit ratings assigned to us by independent ratings agencies, could reduce our access to capital markets, increase our costs of borrowing or adversely impact our ability to obtain favorable financing terms in the future. In particular, if we are unable to access capital and credit markets on terms that are acceptable to us, we may not be able to execute potential merger and acquisition plans, make other investments or fully execute our business plans and strategy.

Our suppliers and customers are also dependent upon the capital and credit markets. Limitations on the ability of customers, suppliers or financial counterparties to access credit could lead to insolvencies of key suppliers and customers, limit or prevent customers from obtaining credit to finance purchases of our products and services, delay institutional, commercial and/or residential construction and remodeling projects and cause delays in the delivery of key products from suppliers.

There are risks associated with our outstanding and future indebtedness.

We had approximately $2.0 billion of outstanding indebtedness at December 31, 2025. We have a senior unsecured revolving credit facility (the "Revolving Facility") that permits borrowings of up to $1.0 billion. A portion of our cash flows from operations is dedicated to servicing our indebtedness and will not be available for other purposes, including our operations, capital expenditures, payment of dividends, share repurchases or future business opportunities or other strategic investments.

At December 31, 2025, we had $190.6 million outstanding on the Revolving Facility, which exposes us to variable interest rate risk. We are also exposed to the risk of continued rising interest rates to the extent we fund our short or long-term financing needs with variable-rate borrowings under the Revolving Facility. If variable base rates under the Revolving Facility increase in the future, our Interest expense could increase as well. For more details about our interest rate exposure under the Revolving Facility, please see Part II. Item 7A.

Table of Contents

Our ability to make scheduled payments or to refinance our debt obligations depends on our financial and operating performance, which is subject to prevailing economic and competitive conditions and to certain financial, business and other factors beyond our control, such as the credit ratings assigned to us by independent ratings agencies or our ability to access capital markets on acceptable terms. If our cash flows and capital resources are insufficient to fund our debt service obligations, we may be forced to reduce or delay capital expenditures, reduce or eliminate the payment of dividends, sell assets, seek additional capital or seek to restructure or refinance our indebtedness. These alternative measures may not be successful and may not permit us to meet our scheduled debt service obligations. In such event, we could face substantial liquidity problems and might be required to sell material assets or operations to attempt to meet our debt service and other obligations. If we are not able to maintain compliance with stated financial covenants or if we breach other covenants in any debt agreement, we could be in default under such agreement or trigger a cross-default of other debt instruments. Such a default would adversely affect our credit ratings, may allow our creditors to accelerate the related indebtedness, and may result in the acceleration of any other indebtedness to which a cross-acceleration or cross-default provision applies.

Strategic and Operational Risks

Increased competition, including from technological developments, could adversely affect our business.

The markets in which we operate include a large number of participants, including multi-national, regional and small, local companies. We primarily compete on the basis of quality, innovation, expertise, effective channels to market, breadth of product offering and price. We may be unable to effectively compete on all these bases. Further, in a number of our product offerings, we compete with our retail customers and technology partners who use their own private labels. If we are unable to anticipate evolving trends in the market or the timing and scale of our competitors’ activities and initiatives, including increased competition from private label brands, the demand for our products and services could be negatively impacted.

In addition, we compete in an industry that is experiencing the convergence of mechanical, electronic and digital products. Technology and innovation play significant roles in the competitive landscape. Our success depends, in part, upon the research, development and implementation of new technologies and products including obtaining, maintaining and enforcing necessary intellectual property protections. Securing and maintaining key partnerships and alliances, recruiting and retaining highly skilled and qualified employee talent and having access to technologies, services, intellectual property and solutions developed by others will play a significant role in our ability to effectively compete. The continual development of new technologies, such as artificial intelligence and machine learning, by existing and new competitors, including non-traditional competitors with significant resources, could adversely affect our ability to sustain operating margins and desirable levels of sales volumes. To remain competitive, we must develop new products and service offerings and respond to new technologies in a timely manner.

Our growth is dependent, in part, on the development, commercialization and acceptance of new products and services.

We must develop and commercialize new products and services that meet the varied and evolving needs of our customers and end-users in order to remain competitive in our current and future markets and in order to continue to grow our business. End- users are continually adopting more advanced technologies in their facilities and homes, accelerated by the increasing adoption of IoT technologies and connected devices, which will require us to devote significant effort and resources to the development, maintenance and enhancement of our IT Systems (as defined below) and other infrastructure required to support and/or enhance the functionality of our electronic products and solutions. The speed of development by our competitors and new market entrants is increasing. We cannot provide any assurance that any new product or service will be successfully commercialized in a timely manner, if ever, or, if commercialized, will result in returns greater than our investment. Investment in a product or service could divert our attention and resources from other projects that become more commercially viable in the market. We also cannot provide any assurance that any new product or service will be accepted by the market.

Changes in customer and consumer preferences and the inability to maintain beneficial relationships with large customers could adversely affect our business.

We have significant customers, particularly major retailers, although no one customer represented 10% or more of our total Net revenues in any of the past three fiscal years. The loss or material reduction of business, either due to a reduction in demand from one or more of our significant customers, or our inability to timely meet any elevated level of customer demand for various reasons, the lack of success of sales initiatives or changes in customer preferences or loyalties for our products related to any such significant customer could have a material adverse impact on our business. In addition, major customers who are volume purchasers are much larger than us and have strong bargaining power with their suppliers. This limits our ability to recover cost increases through higher selling prices. Furthermore, unanticipated inventory adjustments by these customers can have a negative impact on sales.

We also sell our products through various trade channels, including traditional retail and e-commerce channels. If we or our major customers are not successful in navigating the shifting consumer preferences to distribution channels such as e-commerce, our expected future revenues may be negatively impacted.

Table of Contents

If our products or solutions fail to meet certification and specification requirements, are defective, cause, or are alleged to have caused, bodily harm or injury, or otherwise fall short of end-users' needs and expectations, our business may be negatively impacted.

The security and access control product markets we serve often have unique certification and specification requirements, reflecting local regulatory requirements and highly variable end-user needs. While we strive to meet all certification and specification requirements, if any of our products or solutions do not meet such requirements, or contain, or are perceived to contain, defects or otherwise fall short of end-users' needs and expectations, fail to perform as intended, or are otherwise alleged to result in property damage, bodily injury and/or death we may become subject to personal injury lawsuits and/or product liability claims, and if found liable, may incur significant costs, which could negatively impact our business, results of operations or financial condition.

Additionally, electronic security products and solutions are increasingly more sophisticated and technologically complex than the mechanical security products we sell and have an increased risk of design, cybersecurity or manufacturing defects, which could lead to recalls, product replacements or modifications, write-offs of inventory or other assets and significant warranty and other expenses. Product quality issues could also adversely affect the end-user experience, resulting in reputational harm, loss of competitive advantage, poor market acceptance, reduced demand for products and solutions, delay in new product and service introductions and lost sales. Further, adverse publicity, whether or not justified, or allegations of product or service quality issues, even if false or unfounded, could damage our reputation and negatively affect our sales.

Our business and innovation strategies include making acquisitions of, and investments in, external companies. These acquisitions and investments could be unsuccessful, consume significant resources or increase our exposure to cybersecurity, data privacy or other regulatory risks, which could adversely affect our business, financial condition, results of operations and cash flows.

Our long-term growth strategies include the acquisition of businesses or product lines to strengthen our industry position, enhance our existing set of products and services offerings or expand into adjacent markets. However, we cannot provide assurance that we will identify or successfully complete acquisitions with suitable candidates in the future, nor can we provide assurance that completed or future acquisitions will be successful or otherwise achieve the anticipated strategic and financial benefits, including cost and revenue synergies.

Acquisitions often place significant demands on management, operational and financial resources, which could decrease management’s capacity to focus on other important business strategies or divert resources from other parts of our business. Further, the success of future or completed acquisitions will depend, in large part, on the successful integration of operations, sales and marketing, information technology, finance and administrative operations. We cannot provide assurance that we will be able to successfully integrate these new businesses. Additionally, the financing of future business acquisitions may increase our leverage, impact our credit rating and/or diminish our financial position and ability to re-invest in our existing businesses. Future acquisitions may also be dependent on our ability to access the capital and credit markets to obtain new debt or equity financing to fund the purchase price on terms that are acceptable to us.

Some of the businesses we may seek to acquire may be marginally profitable or unprofitable. For these businesses to achieve acceptable levels of profitability, we may need to improve their management, operations, products and market penetration or incur significant capital expenditures. We may not be successful in this regard, the costs of doing so may exceed our original estimates or we may encounter other potential difficulties.

Acquisitions also involve numerous other risks, including:

•Difficulties in obtaining and verifying the financial statements and other business information of acquired businesses;

•Our ability to raise capital on reasonable terms to finance attractive acquisitions;

•Inability to obtain regulatory approvals and/or required financing on favorable terms;

•Potential loss of key employees, key contractual relationships or key customers of acquired companies or of us;

•Difficulties competing in any new markets we may enter;

•Assumption of the liabilities and exposure to unforeseen liabilities (including, but not limited to, regulatory, legal and product or personal liability claims) of acquired companies;

•Cybersecurity related vulnerabilities or data security incidents that may be present in the IT Systems of acquired companies, or emerge when integrating the acquired company into our IT Systems;

•Dilution of interests of holders of our ordinary shares through the issuance of equity securities or equity-linked securities;

•Labor disruptions, work stoppages or other employee-related issues, particularly if employees of the acquired companies are represented by labor unions or trade councils; and

•Difficulty in integrating financial reporting systems and implementing controls, procedures and policies, including disclosure controls and procedures and internal control over financial reporting appropriate for public companies of our size at companies that, prior to the acquisition, had lacked such controls, procedures and policies.

Further, as part of our innovation strategy, from time to time we invest in start-up companies and/or development stage technology or other companies. In evaluating these opportunities, we follow a structured evaluation process that considers factors such as potential financial returns, new expertise in emerging technology and business benefits. Despite our best efforts to calculate potential return and risk, some or all of the companies we invest in may be unprofitable at the time of, and subsequent to, our investment. We may lose money in these investments, including the potential for future impairment charges on the investments, and the anticipated benefits of the technology and business relationships may be less than expected.

We may pursue business opportunities that diverge from our core business.

We may pursue business opportunities that diverge from our core business, including expanding our products or service offerings, seeking to expand our products and services into new international markets, investing in new and unproven technologies and forming new alliances with companies to develop and distribute our products and services. We can offer no assurance that any such business opportunities will prove successful. Certain international markets may be slower than our established markets in adopting our services and products, and our operations in such markets may not develop at a rate that supports our level of investment. Among other negative effects, our investment in new business opportunities may exceed the returns we realize. New investments could have higher cost structures than our current business, which could reduce operating margins and require more working capital. In the event that working capital requirements exceed operating cash flow, we may be required to draw on the Revolving Facility or pursue other external financing, which may not be readily available. In addition to the risks outlined above, expansion into certain new markets may require us to compete with local businesses with greater knowledge of the market, including the tastes and preferences of end-users, and higher market shares.

Our strategic initiatives, including enterprise excellence efforts among other significant capital expenditure projects, may not achieve the improvements or financial returns we expect.

We utilize a number of tools to improve efficiency and productivity. Implementation of new processes to our operations could cause disruptions and may prove to be more difficult, costly or time-consuming than expected. Additionally, from time to time, we undertake substantial capital projects for varying reasons, such as to increase production capacity or to insource certain products, parts or components. We invest in areas we believe best align with our business strategies and that will optimize future returns. However, there can be no assurance that all our planned enterprise excellence projects or other capital expenditures will be fully implemented, or if implemented, will realize the expected improvements or financial returns.

We may not be able to effectively manage and implement restructuring initiatives or other organizational changes.

We have, from time to time, restructured or made other adjustments to our workforce and manufacturing footprint, and may need to do so in the future, in response to market or product changes, performance issues, changes in strategy, acquisitions and/or other internal or external considerations. These restructuring activities and other organizational changes often result in increased restructuring costs, diversion of management’s time and attention from daily operations, cybersecurity and other operational risks and temporarily reduced productivity. If we are unable to successfully manage and implement restructuring and other organizational changes, we may not achieve or sustain the expected growth or cost savings benefits of these activities or do so within the expected timeframe. These effects could recur in connection with future acquisitions and other organizational changes, and our results of operations could be negatively affected.

The effects of global climate change or other unexpected events, including global health crises, may disrupt our operations and have a negative impact on our business.

The effects of global climate change, such as extreme weather conditions and natural disasters occurring more frequently or with more intense effects, or the occurrence of unexpected events including wildfires, tornadoes, hurricanes, earthquakes, floods, tsunamis and other severe hazards in the countries where we operate or sell products and services, could adversely affect our business, financial condition, results of operations and cash flows. These events could disrupt our operations by impacting the availability and cost of materials needed for manufacturing, cause physical damage or closure of our manufacturing sites or distribution centers, lead to loss of human capital and/or cause temporary or long-term disruption in the manufacturing or delivery of products and services to customers. These events and disruptions could also adversely affect our customers’ and suppliers’ financial condition or ability to operate, resulting in reduced customer demand, delays in payments received or supply chain disruptions. Further, these events and disruptions could increase insurance and other operating costs, including impacting our decisions regarding construction of new facilities to select areas less prone to climate change risks and natural disasters, which could result in indirect financial risks passed through the supply chain or other price modifications to our products and services.

Many governmental and other regulatory bodies worldwide are enacting regulations to mitigate the impacts of climate change. If we or others in our supply chain are required to comply with these laws and regulations, or if we choose to take voluntary steps to reduce or mitigate our impact on the climate, we may experience increased costs for energy, production, transportation, and raw materials, increased capital expenditures, or increased insurance premiums and deductibles, each of which could adversely impact our operations. In addition, inconsistent regulations among jurisdictions may also affect our cost to comply with such laws and regulations. Any assessment of the potential impact of future climate change legislation, regulations, or

Table of Contents

industry standards, as well as any international treaties and accords, is uncertain given the wide scope of potential regulatory change in the countries in which we operate.

Global health crises, or outbreak and spread of a communicable disease or virus in the countries where we operate or sell products and provide services, could adversely affect our operations and financial performance. Further, any national, state or local government mandates or other orders taken to minimize the spread of a global health crisis could restrict our ability to conduct business as usual, as well as the business activities of our key customers and suppliers, including the potential for labor shortages. In particular, the ultimate extent of the impact of any epidemic, pandemic or other global health crisis on our business, financial condition and results of operations will depend on future developments which are highly uncertain and cannot be predicted.

We may be subject to risks relating to systems failures or disruptions to our information technology and operational technology systems.

We rely extensively on information technology and operational technology systems, networks and services including hardware, software, firmware and technological applications and platforms (collectively, "IT Systems") to manage and operate our business from end-to-end, including ordering and managing materials from suppliers, design and development, manufacturing, marketing, selling and shipping to customers, invoicing and billing, managing our banking and cash liquidity systems, managing our enterprise resource planning and other accounting and financial systems and complying with regulatory, legal and tax requirements. There can be no assurance that our current IT Systems will function properly. We have invested and will continue to invest in improving our IT Systems. Some of these investments are significant and impact many important operational processes and procedures. There is no assurance that newly implemented IT Systems will improve our current systems, improve our operations or yield the expected returns on the investments. In addition, the implementation of new IT Systems may be more difficult, costly or time-consuming than expected and cause disruptions in our operations and, if not properly implemented and maintained, negatively impact our business. If our IT Systems cease to function properly or if these systems do not provide the anticipated benefits, our ability to manage our operations could be impaired.

As artificial intelligence and machine learning (“AI”) technologies advance and are increasingly adopted by threat actors, the frequency, sophistication and scale of cyberattacks may increase. AI‑enabled methods, including automated vulnerability discovery, automated credential‑stuffing, deepfake‑assisted social engineering and other generative‑AI techniques, could make attacks more successful and harder to detect. In addition, our own or third‑party use of AI could introduce new classes of vulnerabilities. These developments could increase the likelihood and potential impact of disruptions, unauthorized disclosures or other compromises of our IT Systems, products or data, and could increase our remediation and compliance costs, harm our reputation and subject us to regulatory or legal liability.

We currently rely on third-party service providers for many of the critical elements of our global information and operational technology infrastructure, and their failure to provide effective support for such infrastructure could increase our cybersecurity risk or otherwise negatively impact our business and financial results.

We have outsourced many of the critical elements of our global information and operational technology infrastructure to third-party service providers in order to achieve efficiencies. If such service providers experience a disruption due to a cyberattack or other internal or external factors, or they do not perform or perform effectively, we may not be able to achieve the expected efficiencies and may have to incur additional costs to address failures in providing service by the service providers. Depending on the function involved, such non-performance, ineffective performance or failures of service may lead to business disruptions, processing inefficiencies or security breaches.

Cybersecurity incidents could disrupt business operations, result in the loss of critical and confidential information, and adversely impact the Company's reputation, operating results, and financial condition.

Despite our implementation of cybersecurity measures, which have focused on prevention, mitigation, resilience and recovery, our network and products, including access solutions, may be vulnerable to cybersecurity attacks, computer viruses, malicious codes, malware, ransomware, phishing, social engineering, denial of service, hacking, break-ins and similar disruptions. Cybersecurity attacks and intrusion efforts are continuous and evolving, and in certain cases they have been successful at the most robust institutions. The scope and severity of risks that cyber threats present have increased dramatically and include, but are not limited to, malicious software, ransomware attacks, attempts to gain unauthorized access to data or premises, exploiting weaknesses related to vendors or other third parties that could be exploited to attack our systems, denials of service and other electronic security breaches that could lead to disruptions in systems, unauthorized release of confidential or otherwise protected information and corruption of data. Any such event could have a material adverse effect on our business, financial condition, results of operations and cash flows as we face regulatory, reputational and litigation risks resulting from potential cyber incidents, as well as the potential of incurring significant remediation costs. Further, while we maintain insurance coverage that may, subject to policy terms and exclusions, cover certain aspects of our cyber risks, such insurance coverage may be insufficient to cover our losses or all types of claims that may arise in the continually evolving area of cyber risk.

Our networking infrastructure and related assets may be subject to unauthorized access by hackers, employee error or malfeasance or other unforeseen activities. Such issues could result in the disruption of business processes, network degradation

Table of Contents

and system downtime, along with the potential that a third party will exploit our critical assets such as intellectual property, proprietary business information and data related to our customers, suppliers and business partners. To the extent that such disruptions occur, and our business continuity plans do not effectively address these disruptions in a timely manner, they may cause delays in the manufacture or shipment of our products and the cancellation of customer orders and, as a result, our business operating results and financial condition could be materially and adversely affected, resulting in a possible loss of business or brand reputation.

We are exposed to risks related to compliance with data privacy and governance laws.

Our daily business operations also require us to collect and/or retain sensitive data such as intellectual property, proprietary business information and data related to customers, employees, suppliers and business partners within our networking infrastructure including data from individuals subject to the European Union's General Data Protection Regulation, that is subject to privacy and security laws, regulations and/or customer-imposed controls. Despite our efforts to protect such data, the loss or breach of such data due to various causes including material security breaches, catastrophic events, extreme weather, natural disasters, power outages, system failures, computer viruses, improper data handling, programming errors, unauthorized access and employee error or malfeasance could result in wide reaching negative impacts to our business. As such, the ongoing maintenance and security of this information is pertinent to the success of our business operations and our strategic goals.

In addition, we operate in an environment where there are different and potentially conflicting data privacy laws and regulations in effect or expected to go into effect in the future, including regulations related to devices connected through IoT, in the various jurisdictions in which we operate, and we must understand and comply with such laws and regulations while ensuring our data is secure.

Finally, the regulatory environment around cybersecurity is increasingly challenging, with additional reporting requirements around cybersecurity, risk management, strategy and governance, as well as increased disclosure obligations around the occurrence of material cybersecurity incidents. These requirements may present material obligations and risks to our business, including significantly expanded compliance burdens, costs and enforcement risks. We may also be obligated to report a cybersecurity incident before we have been able to fully assess its impact or remediate the underlying issue, and it could potentially reveal system vulnerabilities to threat actors. Failure to timely report incidents under these or other similar rules could also result in monetary fines, sanctions, or subject us to other forms of liability.

Our ability to successfully grow and expand our business depends on our ability to recruit and retain a highly qualified and diverse workforce.

Our ability to successfully grow and expand our business is dependent upon our ability to recruit and retain a workforce with the skills necessary to develop, manufacture and deliver the products and services desired by our customers. We need highly skilled and qualified personnel in multiple areas, including engineering, sales, manufacturing, information technology, cybersecurity, business development, strategy and management. We must therefore continue to effectively recruit, retain and motivate highly qualified, skilled and diverse personnel to maintain our current business and support our projected growth. A shortage of these employees for various reasons, including intense competition for skilled employees, labor shortages, increased labor costs, candidates’ preference to work remotely, changes in laws and policies regarding immigration and work authorizations or any government or public health mandates in jurisdictions where we have operations that may result in workforce attrition and difficulty with recruiting, may jeopardize our ability to grow and expand our business.

In recent years, we have experienced labor shortages and increased turnover rates that have led to, and could in the future lead to, increased costs, such as increased overtime to meet customer demand and increased wage rates to attract and retain employees and could negatively affect our ability to efficiently operate our production facilities or otherwise operate at full capacity. An overall or prolonged labor shortage, lack of skilled labor, increased turnover or sustained level of wage inflation could have a material adverse impact on our business, financial position, results of operations and cash flows.

Disruptions in our global supply chain, including product manufacturing and logistical services provided by our supplier partners, may negatively impact our business.

We procure certain products, including raw materials and other commodities, including steel, zinc, brass and other non-ferrous metals, as well as parts, components (including electronic components) and logistical services from supplier partners located throughout the world. Our ability to meet our customers' needs and achieve cost targets depends on our ability to maintain key manufacturing and supply arrangements, including supplier execution and certain sole supplier or sole manufacturing arrangements. Our reliance on these third parties reduces our control over the manufacturing and delivery process, exposing us to risks including reduced control over product costs and delivery. Additionally, because not all of our supply arrangements provide for guaranteed supply and some key parts and components may be available only from a single supplier or a limited group of suppliers, we are also subject to supply and pricing risks, which could negatively impact our margin performance, results of operations, inventory levels and cash flows.

If we are unable to effectively manage these relationships, or if these third parties experience delays, disruptions, shortages of materials, labor, electronic and other components, capacity constraints, new or increased tariffs and/or other trade restrictions, regulatory issues or quality control problems in their operations, freight delays and other supply chain constraints and

Table of Contents

disruptions, or otherwise fail to meet our future requirements for timely delivery, our ability to ship and deliver certain of our products to our customers could be impaired and our business could be harmed.

Legal and Compliance Risks

We are subject to risks related to corporate social responsibility and reputational matters.

Our reputation and the reputation of our brands, including the perception held by our customers, end-users, business partners, investors, other key stakeholders and the communities in which we do business, are influenced by various factors. There is an increased focus from our stakeholders, as well as regulatory authorities both within the U.S. and internationally, on ESG practices and disclosure. If we fail, or are perceived to have failed, in any number of ESG matters, such as environmental stewardship, good corporate governance, workplace conduct and support for local communities, or to effectively respond to changes in, or new, legal, regulatory or reporting requirements concerning climate change or other sustainability concerns, we may be subject to regulatory fines and penalties, and our reputation or the reputation of our brands may suffer. Further, we have made several public commitments regarding our intended reduction of carbon emissions. Although we intend to meet these commitments, we may be required to expend significant resources to do so, which could increase our operational costs. Further, there can be no assurance of the extent to which any of our commitments will be achieved, or that any future investments we make to achieve such commitments will meet investor, legal and/or any other regulatory expectations and requirements. Moreover, we may determine that it is in the best interest of our Company and our stockholders to prioritize other business, social, governance or sustainable investments over the achievement of our current commitments based on economic, technological developments, regulatory and social factors, business strategy or pressure from investors, activist groups or other stakeholders. If we are unable to meet our commitments, we could incur adverse publicity and reaction from investors, advocacy groups or other stakeholders, which could adversely impact our reputation and brand perception. Such damage to our reputation and the reputation of our brands may negatively impact our business, demand for our products and services, our financial condition and results of operations.

In addition, negative or inaccurate postings or comments on social media or networking websites about our company or our brands could generate adverse publicity that could damage our reputation or the reputation of our brands. If we are unable to effectively manage real or perceived issues, including concerns about product quality, safety, corporate social responsibility or other matters, sentiments toward the Company or our products could be negatively impacted, and our financial results could suffer.

Our brands are important assets of our businesses, and violation of our trademark rights by imitators could negatively impact revenues and brand reputation.

Our brands and trademarks enjoy a reputation for quality and value and are important to our success and competitive position. Unauthorized use of our trademarks may not only erode sales of our products but may also cause significant damage to our brand name and reputation, interfere with relationships with our customers and increase litigation costs. There can be no assurance that our on-going effort to protect our brand and trademark rights will prevent all violations.

Material legal judgments, fines, penalties or settlements imposed against us or our assets could adversely affect our business, financial condition, results of operations and cash flows.

We are currently, and may in the future become, involved in legal proceedings, claims and disputes incidental to the operation of our business in the ordinary course. Our business may be adversely affected by the outcome of these proceedings and other contingencies (including, without limitation, environmental, product and warranty liability, claims for property damage, physical harm or bodily injury, antitrust, intellectual property, data protection, privacy and labor and employment matters) that cannot be predicted with certainty. As required by GAAP, we establish reserves based on our assessment of the probability of contingencies and whether we are able to reasonably estimate the expected range of loss. Subsequent developments in legal proceedings and other contingencies may affect our assessment and estimates of the loss contingency recorded as a reserve, and we may incur additional costs or be required to make material payments beyond our previously recorded reserves.

Allegations that we have infringed the intellectual property rights of third parties could negatively affect us.

We may be subject to claims of infringement of intellectual property rights by third parties. In particular, we often compete in areas having extensive intellectual property rights owned by others, and we have become subject to claims alleging infringement of intellectual property rights of others. In general, if it is determined that one or more of our technologies, products or services infringes the intellectual property rights owned by others, we may be required to cease marketing those products or services, to obtain licenses from the holders of the intellectual property at a material cost or to take other actions to avoid infringing such intellectual property rights. The litigation process is costly and subject to inherent uncertainties, and we may not prevail in litigation matters regardless of the merits of our position. Adverse intellectual property litigation or claims of infringement against us may become extremely disruptive if the plaintiffs succeed in blocking the trade of our products and services and may have a material adverse effect on our business.

Our reputation, ability to do business and results of operations could be impaired by improper conduct by any of our employees, agents or business partners.

We are subject to regulation under a variety of U.S. federal and state and non-U.S. laws, regulations and policies including laws related to anti-bribery and anti-corruption, export and import compliance, competition and anti-money laundering due to our global operations. We provide compliance training for our employees and have other controls and procedures in these areas. We cannot provide assurance that our internal controls will always protect us from the improper conduct of our employees, agents and business partners. Any improper conduct could damage our reputation and subject us to, among other things, civil and criminal penalties, material fines, equitable remedies (including profit disgorgement and injunctions on future conduct), securities litigation, adverse publicity and a general loss of investor or public confidence.

Our operations are subject to regulatory risks related to domestic and international, environmental, health and safety laws.

Our U.S. and non-U.S. operations are subject to a number of laws and regulations, including fire and building codes and EHS standards. We have incurred, and will be required to continue to incur, significant expenditures to comply with these laws and regulations. Changes to, or changes in interpretations of, current laws and regulations, including climate change legislation or other environmental mandates, could require us to increase our compliance expenditures, cause us to significantly alter or discontinue offering existing products and services or cause us to develop new products and services. Altering current products and services or developing new products and services to comply with changes in the applicable laws and regulations could require significant research and development investments, increase the cost of providing the products and services and adversely affect the demand for our products and services. In the event a regulatory authority concludes that we are not or have not at all times been in full compliance with these laws or regulations, we could be fined, criminally charged or otherwise sanctioned.

Certain environmental laws assess liability on current or previous owners of real property or operators of manufacturing facilities for the costs of investigation, removal or remediation of hazardous substances or materials at such properties or at properties at which parties have disposed of hazardous substances. Liability for investigative, removal and remedial costs under certain U.S. federal and state laws and certain non-U.S. laws are retroactive, strict and joint and several. In addition to cleanup actions brought by governmental authorities, private parties could bring personal injury or other claims due to the presence of, or exposure to, hazardous substances. We have received notifications from U.S. and non-U.S. governmental agencies, including the EPA and similar state environmental agencies, that conditions at a number of current and formerly owned sites where we and others have disposed of hazardous substances require investigation, cleanup and other possible remedial action. These agencies may require that we reimburse the government for its costs incurred at these sites or otherwise pay for the costs of investigation and cleanup of these sites, including by providing compensation for natural resource damage claims from such sites. For more information, see "Item 1. Business – Regulatory Matters."

While we have planned for future capital and operating expenditures to maintain compliance with environmental laws and have accrued for costs related to current remedial efforts, our costs of compliance, or our liabilities arising from past or future releases of, or exposures to, hazardous substances, may exceed our estimates. We may also be subject to additional environmental claims for personal injury or cost recovery actions for remediation of facilities in the future based on our past, present or future business activities.

As a global business, we have a relatively complex tax structure, and there is a risk that tax authorities will disagree with our tax positions.

Since we conduct operations worldwide through our subsidiaries, we are subject to complex transfer pricing regulations in the countries in which we operate. Transfer pricing regulations generally require that, for tax purposes, transactions between us and our affiliates be priced on a basis that would be comparable to an arm's length transaction and that contemporaneous documentation be maintained to support the tax allocation. Although uniform transfer pricing standards are emerging in many of the countries in which we operate, there is still a relatively high degree of uncertainty and inherent subjectivity in complying with these rules. To the extent that any tax authority disagrees with our transfer pricing policies, we could become subject to significant tax liabilities and penalties. Our tax returns are subject to review by taxing authorities in the jurisdictions in which we operate. Although we believe we have provided for all tax exposures, the ultimate outcome of a tax review could differ materially from our provisions.

We could be subject to changes in tax rates, the adoption of new tax legislation or exposure to additional tax liabilities.

Our future effective tax rate and cash tax obligations could be adversely affected by shifts in our mix of earnings in countries with varying statutory tax rates, changes in the valuation of our deferred tax assets or liabilities or changes in tax laws, regulations, interpretations or accounting principles, as well as certain discrete items. In addition, we are subject to regular review and audit by tax authorities. As a result, we have received, and may in the future receive, assessments in multiple jurisdictions on various tax-related assertions. Any adverse outcome of such a review or audit could have a negative effect on our operating results and financial condition. In addition, the determination of our worldwide provision for income taxes and other tax liabilities requires significant judgment, and there are many transactions and calculations where the ultimate tax determination is uncertain. Although we believe our estimates are reasonable, the ultimate tax outcome may differ from the

Table of Contents

amounts recorded in our Consolidated Financial Statements and may materially affect our financial results in the period or periods for which such determination is made. Furthermore, due to shifting economic and political conditions, tax policies, laws, interpretations and rates in various jurisdictions may be subject to significant change, which could materially affect our financial position and results of operations. For example, many countries in Europe, as well as a number of other countries and organizations, have proposed, recommended or implemented changes to existing tax laws or have enacted new laws that could significantly increase our effective tax rate or cash tax obligations in countries where we do business or require us to change the manner in which we operate our business. Additionally, the European Commission has been investigating whether various tax regimes or private tax rulings provided by a country to a particular taxpayer may constitute State Aid. We continue to examine the impact the above items may have on our business and the amount of tax we must pay.

The implementation of global tax reforms could negatively impact our financial results.

In recent years, the Organization for Economic Cooperation and Development (“OECD”) has led international efforts to implement various international tax reforms, including the introduction of a global minimum effective corporate tax (“GMT”) rate of 15%, applied on a jurisdiction-by-jurisdiction basis. Over 130 countries agreed to the general framework of the GMT rules and numerous countries in which we operate have transposed those rules into national laws, including Ireland, the location of our incorporation. Additional countries are in various stages of implementing the rules into their national laws.

We anticipate the continued and ongoing release of OECD GMT interpretive guidance and local country GMT legislation. We are continuing to evaluate the potential impact of this interpretative guidance and the release of GMT-implementation legislation in other countries, and such guidance or legislation could result in a material increase in our effective tax rate.

Risks Related to Our Incorporation in Ireland

Irish law differs from the laws in effect in the United States and may afford less protection to holders of our securities.

The U.S. currently does not have a treaty with Ireland providing for the reciprocal recognition and enforcement of judgments in civil and commercial matters. As such, there is some uncertainty as to whether the courts of Ireland would recognize or enforce judgments of U.S. courts obtained against us or our directors or officers based on U.S. federal or state civil liability laws, including the civil liability provisions of the U.S. federal or state securities laws, or hear actions against us or those persons based on those laws.

As an Irish company, we are governed by the Companies Act 2014 of Ireland, as amended, which differs in some material respects from laws generally applicable to U.S. corporations and shareholders, including, among others, differences relating to interested director and officer transactions and shareholder lawsuits. Likewise, the duties of directors and officers of an Irish company generally are owed to the company only. Shareholders of Irish companies generally do not have a personal right of action against directors or officers of the company and may exercise such rights of action on behalf of the company only in limited circumstances. Accordingly, holders of our securities may have more difficulty protecting their interests than would holders of securities of a corporation incorporated in a jurisdiction of the U.S.

In addition, Irish law allows shareholders to authorize share capital which then can be issued by a board of directors without shareholder approval. Also, subject to specified exceptions, Irish law grants statutory preemptive rights to existing shareholders to subscribe for new issuances of shares for cash. At our annual general meeting of shareholders, our shareholders authorized our Board of Directors to issue up to 20% of our issued ordinary shares and further authorized our Board of Directors to issue up to 20% of such shares for cash without first offering them to our existing shareholders. Both of these authorizations will expire after a certain period unless renewed by our shareholders, and we cannot guarantee that the renewal of these authorizations will always be approved. If the Directors' authority to issue ordinary shares is not renewed, then we may be limited in our ability to use our shares, for example, as consideration for acquisitions.

Changes in tax laws, regulations or treaties, changes in our status under the tax laws of many jurisdictions or adverse determinations by taxing authorities could increase our tax burden or otherwise affect our financial condition or operating results, as well as subject our shareholders to additional taxes.

The realization of any tax benefit related to our incorporation and tax residence in Ireland could be impacted by changes in tax laws, tax treaties or tax regulations or the interpretation or enforcement thereof by the tax authorities of many jurisdictions. From time to time, proposals have been made and/or legislation introduced to change the tax laws of various jurisdictions or limit tax treaty benefits that if enacted could materially increase our tax burden and/or our effective tax rate. Moreover, other legislative proposals could have a material adverse impact on us by overriding certain tax treaties and limiting the treaty benefits on certain payments, which could increase our tax liability. We cannot predict the outcome of any specific legislation in any jurisdiction.

While we monitor proposals that would materially impact our tax burden and/or our effective tax rate and investigate our options, we could still be subject to increased taxation on a going forward basis no matter what action we undertake if certain proposals are enacted, certain tax treaties are amended and/or our interpretation of applicable tax law is challenged and determined to be incorrect. In particular, any changes and/or differing interpretations of applicable tax law that have the effect

Table of Contents

of disregarding our incorporation in Ireland, limiting our ability to take advantage of tax treaties between jurisdictions, modifying or eliminating the deductibility of various currently deductible payments or increasing the tax burden of operating or being resident in a particular country, could subject us to increased taxation.

Dividends received by our shareholders may be subject to Irish dividend withholding tax.

In certain circumstances, we are required to deduct Irish dividend withholding tax of 25% from dividends paid to our shareholders. In the majority of cases, shareholders residing in the U.S. will not be subject to Irish withholding tax, and shareholders resident in a number of other countries will not be subject to Irish withholding tax provided that they complete certain Irish dividend withholding tax forms. However, some shareholders may be subject to withholding tax, which could discourage the investment in our stock and adversely impact the price of our shares.

Dividends received by our shareholders may be subject to Irish income tax.

Dividends paid in respect of our shares generally are not subject to Irish income tax where the beneficial owner of these dividends is exempt from Irish dividend withholding tax, unless the beneficial owner of the dividend has some connection with Ireland other than his or her shareholding in Allegion.

Our shareholders who receive their dividends subject to Irish dividend withholding tax will generally have no further liability to Irish income tax on the dividends unless the beneficial owner of the dividend has some connection with Ireland other than his or her shareholding in Allegion.

Certain provisions in our Memorandum and Articles of Association, among other things, could prevent or delay an acquisition of us, which could decrease the trading price of our ordinary shares.

Our Memorandum and Articles of Association contain provisions to deter takeover practices, inadequate takeover bids and unsolicited offers. These provisions include, amongst others:

•A provision of our Articles of Association which generally prohibits us from engaging in a business combination with an interested shareholder (being (i) the beneficial owner, directly or indirectly, of 10% or more of our voting shares or (ii) an affiliate or associate of us that has at any time within the last five years been the beneficial owner, directly or indirectly, of 10% or more of our voting shares), subject to certain exceptions;

•Rules regarding how shareholders may present proposals or nominate directors for election at shareholder meetings;

•The right of our Board of Directors to issue preferred shares without shareholder approval in certain circumstances, subject to applicable law; and

•The ability of our Board of Directors to set the number of directors and to fill vacancies on our Board of Directors.

We believe these provisions will provide some protection to our shareholders from coercive or otherwise unfair takeover tactics. These provisions are not intended to make us immune from takeovers. However, these provisions will apply even if the offer may be considered beneficial by some shareholders and could delay or prevent an acquisition that our Board of Directors determines is in our best interests and our shareholders' best interests. These provisions may also prevent or discourage attempts to remove and replace incumbent directors.

In addition, several mandatory provisions of Irish law could prevent or delay an acquisition of us. For example, Irish law does not permit shareholders of an Irish public limited company to take action by written consent with less than unanimous consent. We also will be subject to various provisions of Irish law relating to mandatory bids, voluntary bids, requirements to make a cash offer and minimum price requirements, as well as substantial acquisition rules and rules requiring the disclosure of interests in our shares in certain circumstances. Also, Irish companies, including us, may alter their Memorandum of Association and Articles of Association only with the approval of at least 75% of the votes of the company’s shareholders cast in person or by proxy at a general meeting of the company.

Item 1C. CYBERSECURITY

Risk Management and Strategy

Allegion plc recognizes the significance of developing, implementing and maintaining cybersecurity measures to safeguard our information systems and products and protect the confidentiality, integrity and availability of our data.

Managing Material Risks & Integrated Overall Risk Management

Cybersecurity is a critical part of our enterprise risk management. To address cybersecurity threats, we leverage a multi-layer approach, with our Chief Information Security Officer (“CISO”) leading a team that is responsible for forming our enterprise-wide information security strategy, training, policy, standards, architecture and processes to protect us against cybersecurity risks. Our risk management group works with our cybersecurity team to continuously evaluate and address cybersecurity risks.

Table of Contents

All employees are required to comply with our information security policies and are responsible for helping protect our information security, including promptly reporting suspected security events through established channels. We maintain an employee security awareness program and a security training program for technical personnel that provide mandatory and on‑demand training. As part of these programs, every employee is expected to report any suspected security event immediately upon discovery. Employees may report incidents through established channels such as the security operations mailbox, our ticketing portal or service desk, or by contacting local IT support.

Engage Third Parties on Risk Management

We engage a range of external experts, including cybersecurity consultants and auditors to evaluate and test our risk management systems. Our collaboration with these third parties includes regular audits, threat assessments, and consultation on security enhancements. Our cybersecurity programs generally align with the NIST Cybersecurity Framework 2.0, and third-party audits on portions of our cybersecurity program or processes apply the NIST Cybersecurity Framework 2.0 controls. These partnerships provide expert knowledge and insights, which are designed to ensure our cybersecurity strategies and processes are consistent with industry best practices.

Oversee Third-party Risk

We rely on our information technology systems and networks in connection with many of our business activities. Some of these networks and systems are managed by third-party service providers and are not under our direct control. The Company has implemented processes designed to manage the cybersecurity risks associated with its use of third-party service providers.

Risks from Cybersecurity Threats

Despite the security measures we have implemented, certain cyber incidents could materially disrupt operational systems; result in loss of trade secrets or other proprietary or competitively sensitive information; compromise personally identifiable information regarding customers or employees; delay our ability to deliver products to customers; and/or jeopardize the security of our facilities. The adoption of AI by threat actors has resulted in more sophisticated and scalable attacks. These may include AI‑enabled social engineering, deepfake impersonation, automated vulnerability discovery and exploitation of AI models themselves. The use of AI by our stakeholders, including vendors and customers, may also introduce new vulnerabilities into our ecosystem. These risks are further described in the risk factors within Item 1A, particularly under the headings “We may be subject to risks relating to systems failures or disruptions to our information technology and operational technology systems;” “We currently rely on third-party service providers for many of the critical elements of our global information and operational technology infrastructure, and their failure to provide effective support for such infrastructure could increase our cybersecurity risk or otherwise negatively impact our business and financial results;” and “Disruptions or breaches of our information systems could adversely affect us.”

We have not encountered any risks from cybersecurity threats, including as a result of any previous cybersecurity incidents, that have materially affected or are reasonably likely to materially affect us, including our business strategy, results of operations or financial condition.

Governance

The Board of Directors (the "Board") has established oversight mechanisms designed to ensure effective governance in managing risks associated with cybersecurity threats.

Board of Directors Oversight

Due to the importance of cybersecurity to the Company, the full Board is charged with oversight responsibility for our risk management and security strategy and policy. The Board is composed of members with diverse expertise including, risk management, information technology, engineering, manufacturing, innovation and finance, equipping them to oversee cybersecurity risks effectively. The Board receives updates from the CISO and management at least quarterly at board meetings, which updates cover the Company's cybersecurity strategy, current cybersecurity risk assessment, key risk areas, current cyber trends and any significant cyber incidents that have occurred or are reasonably likely to occur.

Management’s Role

Management is responsible for assessing and managing cybersecurity risk. Specifically, the CISO is responsible for the prevention, mitigation, detection and remediation of cybersecurity incidents. The CISO regularly meets with the Chief Executive Officer (“CEO”) and Executive Leadership Team to inform them on cybersecurity risks. These briefings encompass a broad range of topics, including:

•Threat intelligence;

•Risk updates with regional vice presidents;

•Third-party assessments and results of tabletop exercises;

•Training programs for employees;

•Results of phishing simulations;

•Cybersecurity technologies and best practices; and

•Significant cybersecurity incidents and/or trends (if any).

Table of Contents

Risk Management Personnel

Primary responsibility for assessing, monitoring and managing our cybersecurity risks rests with the CISO. With over 20 years of experience in the field of information technology, the CISO brings a wealth of expertise to the role. The CISO’s education includes a Master’s in Cybersecurity Management. The CISO has in-depth knowledge and experience in developing and executing our cybersecurity strategies. The CISO oversees our governance programs, tests our compliance with standards, remediates known risks and leads our comprehensive employee security awareness program. The CISO is also responsible for building and overseeing a cybersecurity team, including internal and external resources, who provide subject matter expertise and operational talents to achieve our cybersecurity objectives.

Monitor Cybersecurity Incidents

The CISO and the cybersecurity team are continually informed about the latest developments in cybersecurity, including potential threats and innovative risk management techniques, which is an important component in designing programs to prevent, detect, mitigate and remediate cybersecurity incidents. This includes monitoring emerging AI-driven threats and adapting our detection, prevention and response capabilities to address them. The CISO implements and oversees processes for the regular monitoring of our information systems. This includes the deployment of advanced security measures and regular system audits to identify potential vulnerabilities. In the event of a cybersecurity incident, we have a well-defined incident response plan. This plan includes immediate actions to mitigate the impact and long-term strategies for remediation and prevention of future incidents and informing the board of significant cyber incidents in accordance with the Company’s incident response plan.

Item 2. PROPERTIES

We operate through a broad network of production and assembly facilities, distribution centers, sales offices and engineering centers, across North America, Europe, Asia and Oceania. Our production and assembly facilities for the Allegion Americas business segment are primarily located in the United States, Mexico and Canada, and for the Allegion International business segment primarily in Australia, France, Germany, Italy, the Netherlands, New Zealand, Poland, Spain and the United Kingdom. Our active properties represent approximately 7.7 million square feet, of which approximately 45% is leased.

We own 16 of our 37 production and assembly facilities, with the remaining 21 under long-term lease arrangements. We believe our plants are well maintained, generally in good condition and suitable for the conduct of our business.

Item 3. LEGAL PROCEEDINGS

In the normal course of business, we are involved in a variety of lawsuits, claims and legal proceedings, including commercial and contract disputes, employment matters, product liability claims, environmental liabilities, intellectual property disputes and tax-related matters. In our opinion, pending legal matters are not expected to have a material adverse impact on our results of operations, financial condition, liquidity or cash flows.

This item should be read in conjunction with the Risk Factors set forth in Part I. Item 1A of this Form 10-K.

Item 4. MINE SAFETY DISCLOSURES

PART II

Item 5. MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND

ISSUER PURCHASES OF EQUITY SECURITIES

Our ordinary shares are traded on the New York Stock Exchange under the symbol ALLE. As of February 12, 2026, the number of record holders of ordinary shares was 1,635.

Dividend Policy

Our Board of Directors declared dividends of $0.51 per ordinary share on February 6, 2025, April 10, 2025, September 4, 2025 and December 3, 2025. On February 4, 2026, our Board of Directors declared a dividend of $0.55 per ordinary share payable on March 31, 2026, to shareholders of record on March 13, 2026. We paid a total of $175.3 million in cash for dividends to ordinary shareholders during the year ended December 31, 2025. Future dividends on our ordinary shares, if any, will be at the discretion of our Board of Directors and will depend on, among other things, our results of operations, cash requirements and surplus, financial condition, contractual restrictions (including under the agreements governing our indebtedness) and other factors that the Board of Directors may deem relevant, as well as our ability to pay dividends in compliance with the Irish Companies Act. Under the Irish Companies Act, dividends and distributions may only be made from distributable reserves. Distributable reserves, broadly, means the accumulated realized profits of Allegion plc ("ALLE-Ireland") which are unrelated to any GAAP reported amounts (e.g., retained earnings). As of December 31, 2025, we had distributable reserves of $4.1 billion. In addition, no distribution or dividend may be made unless the net assets of ALLE-Ireland are equal to, or in excess of, the aggregate of ALLE-Ireland’s called up share capital plus undistributable reserves, and the distribution or dividend does not reduce ALLE-Ireland’s net assets below such aggregate.

Our Board of Directors has approved a share repurchase program (the "Share Repurchase Authorization") which authorizes the repurchase of up to, and including, $500 million of the Company's ordinary shares. The Share Repurchase Authorization does not have a prescribed expiration date and does not oblige the Company to acquire any particular amount of the Company's ordinary shares. Share repurchases may be made from time to time in open market, accelerated stock repurchase or privately negotiated transactions, including pursuant to one or more Rule 10b5-1 trading plans. The timing and manner of any share repurchase and the actual number of ordinary shares repurchased will be determined at the discretion of management based on a variety of factors, including, among others, the Company’s stock price, corporate and regulatory requirements, and other general market and economic conditions. The Board of Directors may suspend, modify or terminate the repurchase program at any time without prior notice.

Item 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations contains forward-looking statements that involve risks and uncertainties. Our actual results may differ materially from the results discussed in the forward-looking statements. Factors that might cause a difference include, but are not limited to, those discussed under Part I, Item 1A. Risk Factors in this Annual Report on Form 10-K. The following section is qualified in its entirety by the more detailed information, including our consolidated financial statements and the notes thereto, which appears elsewhere in this Annual Report on Form 10-K.

Overview

Organization

We are a leading global provider of security products and solutions operating in two segments: Allegion Americas and Allegion International. We sell a wide range of security products and solutions for end-users in commercial, institutional and residential facilities worldwide, including the education, healthcare, government, hospitality, retail, commercial office and single and multi-family residential markets. Our leading brands include CISA®, Interflex®, LCN®, Schlage®, SimonsVoss® and Von Duprin®.

Recent Developments

Business and Industry Trends and Outlook and Global Trade and Macroeconomic Environment

In 2025, we delivered high-single digit revenue growth compared to 2024, driven by favorable pricing and volume growth, as well as the impact from acquisitions made during the year. Demand for electronic security products has also remained strong and continues to be a long-term growth driver.

Throughout 2025, the U.S. government announced tariffs on imports from several countries from which we manufacture and/or import products and components. In 2025, we offset inflation due to tariffs with pricing actions. We continue to analyze the impact of changes in tariffs and what, if any, steps, including pricing actions, we may take to mitigate the impact of the tariffs. We estimate we source approximately 20-25% of cost of goods sold ("COGS") from Mexico, less than 5% of COGS from China, and 5-10% of COGS from all other non-US countries. Additionally, this could impact future demand.

The demand trends and macroeconomic conditions discussed above and a number of other challenges and uncertainties that could affect our businesses are described under Part I, Item 1A, "Risk Factors."

2025 and 2024 Significant Events

Acquisitions

We have made several recent business acquisitions across our Allegion Americas and Allegion International segments. The acquisitions align with our strategy of expanding our mechanical and electronic product portfolios and adding complimentary software and services. This includes the acquisition of ELATEC, including Elatec GmbH and other group entities ("ELATEC") on July 1, 2025. ELATEC is a manufacturer of security and access technology based in Germany, and the acquisition helps expand our global electronics portfolio in attractive end markets while also increasing strategic relationships with channel partners.

The aggregate consideration, inclusive of contingent consideration and net of cash acquired, for all acquisitions completed in 2025 and 2024 was approximately $631.6 million and $147.2 million, respectively. Businesses acquired in 2025 generated $93.0 million of Net revenues since the acquisition dates, which is included within our Consolidated Statements of Comprehensive Income.

See Note 3 to the Consolidated Financial Statements for further information.

Financing Activities

On December 9, 2025, we amended and restated our unsecured revolving credit facility (the "Revolving Facility") which, among other things, increased the total commitment from $750.0 million to $1.0 billion, and extended the maturity from May 20, 2029 to May 20, 2030. We used borrowings under the Revolving Facility to repay our outstanding term loan, which was scheduled to mature in November 2026. Outstanding borrowings under the Revolving Facility were $190.6 million at December 31, 2025.

Dividends and Share Repurchases

During 2025, we paid quarterly dividends of $0.51 per ordinary share to shareholders on record as of March 14, 2025, June 13, 2025, September 15, 2025, and December 16, 2025, for a total of $175.3 million, and repurchased approximately 0.6 million ordinary shares for approximately $80.0 million.

Table of Contents

During 2024, we paid quarterly dividends of $0.48 per ordinary share to shareholders on record as of March 15, 2024, June 14, 2024, September 20, 2024, and December 17, 2024, for a total of $167.0 million, and repurchased approximately 1.6 million ordinary shares for approximately $220.0 million.

The discussions that follow describe the significant factors contributing to the changes in our results of operations for the years presented and form the basis used by management to evaluate the financial performance of the business. For a discussion of our results of operations for the year ended December 31, 2024, compared to the year ended December 31, 2023, see “Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our 2024 Annual Report on Form 10-K filed with the SEC on February 18, 2025.

Net Revenues

Net revenues for the year ended December 31, 2025, increased by 7.8%, or $295.1 million, as compared to the year ended December 31, 2024, due to the following:


Pricing	3.1	%
Volume	1.0	%
Acquisitions / divestitures	3.1	%
Currency exchange rates	0.6	%
Total	7.8	%

The increase in Net revenues was driven by improved pricing, favorable impact from acquisitions / divestitures, higher volumes and favorable foreign currency exchange rate movements.

Pricing includes increases or decreases of price, including discounts, surcharges and/or other sales deductions, on our existing products and services. Volume includes increases or decreases of revenue due to changes in unit volume of existing products and services, as well as new products and services.

Cost of Goods Sold

For the year ended December 31, 2025, Cost of goods sold as a percentage of Net revenues decreased to 54.8% from 55.8%, as compared to the year ended December 31, 2024, due to the following:


Pricing and productivity in excess of inflation and investment spending	(0.1)	%
Volume / product mix	(0.6)	%

Currency exchange rates	(0.2)	%
Restructuring / integration / acquisition expenses	(0.1)	%
Total	(1.0)	%

Cost of goods sold as a percentage of Net revenues decreased primarily due to favorable product mix, favorable foreign currency exchange rate movements, a year-over-year decrease in restructuring, integration, and acquisition expenses and pricing and productivity, which exceeded the impacts from inflation and investment spending.

Pricing and productivity in excess of inflation and investment spending includes the impact to Cost of goods sold from pricing, as defined above, in addition to productivity, inflation and investment spending. Productivity represents improvements in unit costs of materials and cost reductions related to improvements to our manufacturing design and processes. Inflation includes unit costs for the current period compared to the average actual cost for the prior period, multiplied by current year volumes. Expenses related to increased head count for strategic initiatives, new facilities or other significant spending for strategic

initiatives or new product and channel development, are captured in investment spending. Volume/product mix represents the impact due to increases or decreases of revenue due to changes in unit volume, including new products and services, including the effect of changes in the mix of products and services sold on Cost of goods sold.

Selling and Administrative Expenses

For the year ended December 31, 2025, Selling and administrative expenses as a percentage of Net revenues increased to 24.1% from 23.5%, as compared to the year ended December 31, 2024, due to the following:


Inflation in excess of productivity and investment spending	0.5	%
Volume leverage	(0.2)	%


Restructuring / integration / acquisition expenses	0.3	%
Total	0.6	%

Selling and administrative expenses as a percentage of Net revenues increased due to inflation in excess of productivity and investment spending and a year-over-year increase in restructuring, integration, and acquisition expenses. These increases were partially offset by the favorable impact of higher volume leverage.

Volume leverage represents the contribution margin related to changes in sales volume, excluding the impact of price, productivity, mix and inflation. Expenses related to increased head count for strategic initiatives, new facilities or significant spending for strategic initiatives or new product and channel development, are captured in investment spending in the table above.

Operating Income/Margin

Operating income for the year ended December 31, 2025, increased $78.8 million as compared to the year ended December 31, 2024, and Operating margin increased to 21.1% from 20.7%, due to the following:


In millions	Operating Income		Operating Margin
December 31, 2024	$	780.7	20.7	%
Pricing and productivity in excess of inflation and investment spending	8.7		(0.4)	%
Volume / product mix	41.1		0.9	%
Currency exchange rates	9.1		—	%
Acquisitions / divestitures	24.4		—	%
Restructuring / integration / acquisition expenses	(4.5)		(0.1)	%


December 31, 2025	$	859.5	21.1	%

The increase in Operating income was driven by favorable volume/product mix, the favorable impact from acquisitions/divestitures, favorable foreign currency exchange rate movements, and pricing and productivity improvements in excess of inflation and investment spending. These increases were partially offset by higher restructuring, integration, and acquisition expenses.

The increase in Operating margin was driven by favorable volume/product mix, which was partially offset by lower operating margin from pricing and productivity in excess of inflation and investment spending and higher restructuring, integration and acquisition expenses.

Interest Expense

Interest expense for the year ended December 31, 2025, decreased $1.0 million as compared to the year ended December 31, 2024, primarily due to a lower weighted-average interest rate on our outstanding indebtedness.

Other Income, net

The components of Other income, net, for the years ended December 31 were as follows:


In millions	2025		2024
Interest income	$	(12.0)	$	(20.5)
Currency translation loss	3.4		2.2
Earnings and gains from the sale of equity method investments, net	(1.6)		(1.1)
Net periodic pension and postretirement benefit (income) cost, less service cost	1.0		(0.2)
Other income	(0.7)		(0.5)
Other income, net	$	(9.9)	$	(20.1)

For the year ended December 31, 2025, Other income, net, decreased $10.2 million compared to 2024, primarily due to less interest income generated as a result of less cash on hand throughout the year due to the increase in acquisition activity.

Provision for Income Taxes

For the year ended December 31, 2025, our effective tax rate was 16.2%, compared to 14.5% for the year ended December 31, 2024. The increase in the effective income tax rate was primarily due to the unfavorable mix of income earned in higher tax rate jurisdictions and year over year changes in amounts recognized for uncertain tax positions and income tax credits, which were partially offset by the enactment of legislative changes.

Review of Business Segments

We operate in and report financial results for two segments: Allegion Americas and Allegion International. These segments represent the level at which our chief operating decision maker ("CODM") reviews our financial performance and makes operating decisions.

Segment operating income is the measure of profit and loss that our CODM uses to evaluate the financial performance of the business and as the basis for resource allocation, performance reviews and compensation. For these reasons, we believe Segment operating income represents the most relevant measure of Segment profit and loss. Our CODM may exclude certain charges or gains, such as corporate charges and other special charges, to arrive at a Segment operating income that is a more meaningful measure of profit and loss upon which to base our operating decisions. We define Segment operating margin as Segment operating income as a percentage of the segment's Net revenues.

The segment discussions that follow describe the significant factors contributing to the changes in results for each segment included in Net earnings.

The increase in Net revenues was driven by improved pricing, the favorable impact of acquisitions and higher volumes. These increases were partially offset by unfavorable foreign currency exchange rate movements.

Excluding Net revenues of businesses acquired in 2025, Net revenues from non-residential products grew by a high-single digits percent compared to the prior year, driven by increased pricing and higher volumes, and Net revenues from residential

Table of Contents

products decreased by a low-single digits percent compared to the prior year, driven by lower volumes, partially offset by increased pricing.

Growth in Americas electronic security products and solutions is a metric monitored by management and a focus of our investors. Electronic products encompass both residential and non-residential products, and include all electrified product categories including, but not limited to, electronic and electrified locks, access control systems and electronic and electrified door controls and systems and exit devices. Net revenues from the sale of electronic products increased by a low-double digits percent compared to 2024. We continue to believe electronic products are a long-term growth driver.

December 31, 2025	$	76.5	9.0	%

The increases in Segment operating income and Segment operating margin were primarily driven by the favorable impact from acquisitions/divestitures and favorable movements in foreign currency exchange rates. These increases were partially offset by higher restructuring, integration and acquisition expenses, unfavorable volume/product mix and inflation and investment spending in excess of pricing and productivity improvements. Macroeconomic conditions in our International markets remain mixed.

Liquidity and Capital Resources

Liquidity Outlook, Sources and Uses

Our primary source of liquidity is cash provided by operating activities. Cash provided by operating activities is used to invest in new product development and fund capital expenditures and working capital requirements. Our ability to generate cash from our operating activities, our unused availability under the Revolving Facility and our access to the capital and credit markets enable us to fund these capital needs, execute our long-term growth strategies and return value to our shareholders. Further, our business operates with strong operating cash flows, low leverage and low capital intensity, providing us financial flexibility.

Our short-term financing needs primarily consist of working capital requirements, restructuring initiatives, capital spending, potential acquisitions, dividend payments and principal and interest payments on our long-term debt. Long-term financing needs depend largely on potential growth opportunities, including potential acquisitions, repayment or refinancing of our long-term obligations and repurchases of our ordinary shares. Of our total outstanding indebtedness as of December 31, 2025, approximately 90% incurs fixed-rate interest and is therefore not exposed to the risk of rising variable interest rates.

Based upon our operations, existing cash balances and unused availability under the Revolving Facility, as of December 31, 2025, we expect cash flows from operations to be sufficient to maintain a sound financial position and liquidity and to meet our financing needs for at least the next twelve months. Further, we do not anticipate any covenant compliance challenges with any of our outstanding indebtedness for at least the next twelve months. We also believe unused availability under the Revolving Facility and access to credit and capital markets are sufficient to achieve our longer-term strategic plans.

The following table reflects the major categories of cash flows for the years ended December 31. For additional details, see the Consolidated Statements of Cash Flows in the Consolidated Financial Statements.


In millions	2025		2024
Net cash provided by operating activities	$	783.8	$	675.0
Net cash used in investing activities	(685.5)		(228.4)
Net cash used in financing activities	(266.7)		(394.5)

Operating activities: Net cash provided by operating activities for the year ended December 31, 2025, increased by $108.8 million compared to 2024, driven primarily by higher net earnings and less cash used for working capital.

Investing activities: Net cash used in investing activities for the year ended December 31, 2025, increased by $457.1 million compared to 2024, primarily due to higher cash used for acquisitions and an increase in capital expenditures.

Financing activities: Net cash used in financing activities for the year ended December 31, 2025, decreased by $127.8 million compared to 2024. The change in cash used in financing activities was primarily due to a decrease in cash used for share repurchases, partially offset by higher net repayments on debt and higher dividend payments.

We have an unsecured revolving credit facility (the "Revolving Facility") in place, of which $190.6 million was outstanding at December 31, 2025. We paid the outstanding $212.5 million principal balance and interest on a term loan facility during the year ended December 31, 2025 using cash on hand and borrowings under the Revolving Facility. On December 9, 2025, we amended and restated the Revolving Facility which, among other things, increased the total commitment from $750.0 million to $1.0 billion, and extended the maturity from May 20, 2029 to May 20, 2030.

The Revolving Facility provides aggregate commitments of up to $1.0 billion, which includes up to $100.0 million for the issuance of letters of credit. We had $25.2 million and $18.4 million of letters of credit outstanding at December 31, 2025 and 2024, respectively. Borrowings under the Revolving Facility may be repaid at any time without premium or penalty, and amounts repaid may be reborrowed. We pay certain fees with respect to the Revolving Facility, including an unused commitment fee on the undrawn portion of between 0.080% and 0.200% per year, depending on the Company's credit ratings, as well as certain other fees.

Outstanding borrowings under the Revolving Facility accrue interest, at our option, of (i) a SOFR plus an applicable margin, or (ii) a base rate (as defined in the credit agreement) plus an applicable margin. The applicable margin ranges from 0.875% to 1.375% depending on our credit ratings. At December 31, 2025, our outstanding borrowings under the Revolving Facility accrued interest at SOFR plus a margin of 1.125%, resulting in an interest rate of 4.902%. The credit agreement also contains negative and affirmative covenants and events of default that, among other things, limit or restrict our ability to enter into certain transactions. In addition, the Revolving Facility requires us to comply with a maximum leverage ratio as defined in the credit agreement. As of December 31, 2025, we were in compliance with all applicable covenants under the credit agreement.

As of December 31, 2025, we also have $400.0 million outstanding of our 3.550% Senior Notes due 2027 (the “3.550% Senior Notes”), $600.0 million outstanding of our 5.411% Senior Notes due 2032 (the “5.411% Senior Notes”), $400.0 million outstanding of the 5.600% Senior Notes due 2034 (the "5.600% Senior Notes") and $400.0 million outstanding of its 3.500% Senior Notes due 2029 (the “3.500% Senior Notes”, and all four senior notes collectively, the "Senior Notes"). The 3.550% Senior Notes and 3.500% Senior Notes both require semi-annual interest payments on April 1 and October 1 of each year and mature on October 1, 2027 and October 1, 2029, respectively. The 5.411% Senior Notes require semi-annual interest payments on January 1 and July 1 of each year and mature on July 1, 2032. The 5.600% Senior Notes require semi-annual interest payments on May 29 and November 29 of each year and mature on May 29, 2034.

Historically, the majority of our earnings were considered to be permanently reinvested in jurisdictions where we have made, and intend to continue to make, substantial investments to support the ongoing development and growth of our global operations. At December 31, 2025, we analyzed our working capital requirements and the potential tax liabilities that would be incurred if certain subsidiaries made distributions and concluded that no material changes to our historic permanent reinvestment assertions were required.

Scheduled future principal repayments on our outstanding indebtedness can be found in Note 8 to the Consolidated Financial Statements. Interest payments related to our long-term indebtedness in 2026 are expected to be $90-95 million, given our current level of indebtedness and effective interest rates as of December 31, 2025.

Contractual Obligations and Other Commitments

In addition to the scheduled principal and interest payments discussed above, our material cash requirements include the following contractual and other obligations:

Table of Contents

Purchase Commitments – We occasionally enter into short-term, firm purchase commitments to mitigate pricing risk related to certain of our commodity, parts and component purchases, which represent commitments under enforceable and legally binding agreements. Such purchase commitments are made in the normal course of business and are not anticipated to materially impact our liquidity or financial position over the next twelve months. See Note 19 to the Consolidated Financial Statements for further information.

Leases – We have numerous real estate and equipment leasing arrangements for which we are a lessee. See Note 10 to the Consolidated Financial Statements for further information as to the short and long-term lease liabilities included within the Consolidated Balance Sheets, as well as future minimum lease payments for 2026 and future years.

Defined Benefit Plans – Our investment objective in managing defined benefit plan assets is to ensure that all present and future benefit obligations are met as they come due. We seek to achieve this goal while trying to mitigate volatility in plan funded status, contributions and expense by matching the characteristics of the plan assets to that of the plan liabilities. Global asset allocation decisions are based on a dynamic approach whereby a plan's allocation to fixed income assets increases as the funded status increases. We monitor plan funded status, asset allocation and the impact of market conditions on our defined benefit plans regularly in addition to investment manager performance. None of our defined benefit plans have experienced a significant impact on their liquidity due to volatility in the markets.

At December 31, 2025, we had net pension assets of $14.6 million, which consist of plan assets of $498.5 million and benefit obligations of $483.9 million. It is our objective to contribute to our pension plans in order to ensure adequate funds are available to make benefit payments to plan participants and beneficiaries when required. At December 31, 2025, the funded status of our U.S. pension plans increased to 101.0% from 100.8% at December 31, 2024. The funded status for our non-U.S. pension plans increased to 104.8% at December 31, 2025 from 101.4% at December 31, 2024. The funded status for all of our pension plans at December 31, 2025 increased to 103.0% from 101.1% at December 31, 2024. We currently expect to contribute approximately $3.9 million to our plans worldwide in 2026.

Determining the costs and obligations associated with our defined benefit plans is dependent on various actuarial assumptions including discount rates, expected returns on plan assets, employee mortality and turnover rates. Changes in any of the assumptions can have an impact on the net periodic pension benefit cost. An estimated 0.5% rate decline in the discount rate would have increased net periodic pension benefit cost by approximately $0.4 million in 2025, while a 0.5% rate decline in the estimated return on assets would have increased net periodic pension benefit cost by approximately $2.2 million. For further details on defined benefit plan activity, see Note 11 to the Consolidated Financial Statements.

Income Taxes – At December 31, 2025, we have total unrecognized tax benefits for uncertain tax positions of $54.8 million and $12.0 million of related accrued interest and penalties, net of tax, although we are unable to reasonably estimate the timing over which these liabilities might be paid. See Note 16 to the Consolidated Financial Statements for additional information regarding matters relating to income taxes, including unrecognized tax benefits and tax authority disputes.

Contingent Liabilities – We are involved in various litigation, claims and administrative proceedings, including those related to environmental, asbestos-related and product liability matters. We believe that these liabilities are subject to the uncertainties inherent in estimating future costs for contingent liabilities and will likely be resolved over an extended period of time. See Note 19 to the Consolidated Financial Statements for additional information.

Guarantor Financial Information

Allegion US Hold Co is the issuer of the 3.550% Senior Notes, 5.411% Senior Notes, and 5.600% Senior Notes and is the guarantor of the 3.500% Senior Notes. Allegion plc (the “Parent”) is the issuer of the 3.500% Senior Notes and is the guarantor of the 3.550% Senior Notes, 5.411% Senior Notes, and 5.600% Senior Notes. Allegion US Hold Co is directly or indirectly 100% owned by the Parent and each of the guarantees of Allegion US Hold Co and the Parent is full and unconditional and joint and several.

The 3.550% Senior Notes, 5.411% Senior Notes, and 5.600% Senior Notes are senior unsecured obligations of Allegion US Hold Co and rank equally with all of Allegion US Hold Co’s existing and future senior unsecured and unsubordinated indebtedness. The guarantee of the 3.550% Senior Notes, 5.411% Senior Notes, and 5.600% Senior Notes is the senior unsecured obligation of the Parent and ranks equally with all of the Parent’s existing and future senior unsecured and unsubordinated indebtedness. The 3.500% Senior Notes are senior unsecured obligations of the Parent and rank equally with all of the Parent’s existing and future senior unsecured and unsubordinated indebtedness. The guarantee of the 3.500% Senior Notes is the senior unsecured obligation of Allegion US Hold Co and ranks equally with all of Allegion US Hold Co's existing and future senior unsecured and unsubordinated indebtedness.

Each guarantee is effectively subordinated to any secured indebtedness of the guarantor to the extent of the value of the assets securing such indebtedness. The Senior Notes are structurally subordinated to indebtedness and other liabilities of the subsidiaries of the guarantor, none of which guarantee the notes. The obligations of the guarantor under its guarantee are limited as necessary to prevent such guarantee from constituting a fraudulent conveyance under applicable law and, therefore, are limited to the amount that the applicable guarantor could guarantee without such guarantee constituting a fraudulent conveyance; this limitation, however, may not be effective to prevent such guarantee from constituting a fraudulent

Table of Contents

conveyance. If the guarantee was rendered voidable, it could be subordinated by a court to all other indebtedness (including guarantees and other contingent liabilities) of the guarantor, and, depending on the amount of such indebtedness, the applicable guarantor’s liability on its guarantee could be reduced to zero. In such an event, the notes would be structurally subordinated to the indebtedness and other liabilities of the applicable guarantor.

For further details, terms and conditions of the Senior Notes refer to the Company’s Forms 8-K filed October 2, 2017, September 27, 2019 June 22, 2022, and May 29, 2024.

The following tables present the summarized financial information specified in Rule 1-02(bb)(1) of Regulation S-X for each issuer and guarantor. The summarized financial information has been prepared in accordance with Rule 13-01 of Regulation S-X.

Critical Accounting Estimates

Management’s Discussion and Analysis of Financial Condition and Results of Operations are based upon our Consolidated Financial Statements, which have been prepared in accordance with GAAP. The preparation of financial statements in accordance with GAAP requires management to use judgment in making estimates and assumptions based on the relevant information available at the end of each period. These estimates and assumptions have a significant effect on reported amounts of assets and liabilities, revenues and expenses as well as the disclosure of contingent assets and liabilities because they result primarily from the need to make estimates and assumptions on matters that are inherently uncertain. Actual results may differ from estimates. If updated information or actual amounts are different from previous estimates, the revisions are included in our results for the period in which they become known.

The following is a summary of certain accounting estimates and assumptions made by management that we consider critical:

•Goodwill – Goodwill is tested annually during the fourth quarter for impairment or when there is a significant change in events or circumstances that indicate the fair value of a reporting unit is, more likely than not, less than its carrying amount. Recoverability of goodwill is measured at the reporting unit level and starts with a comparison of the carrying amount of a reporting unit to its estimated fair value. If the estimated fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is not impaired. To the extent that the carrying value of a reporting unit exceeds

Table of Contents

its estimated fair value, a goodwill impairment charge will be recognized for the amount by which the carrying value of the reporting unit exceeds its fair value, not to exceed the carrying amount of the reporting unit's goodwill.

As quoted market prices are not available for our reporting units, the calculation of their estimated fair values is based on two valuation techniques, a discounted cash flow model (income approach) and a market multiple of earnings (market approach), with each method being weighted in the calculation. The income approach relies on our estimates of revenue growth rates, margin assumptions and discount rates to estimate future cash flows and explicitly addresses factors such as timing, with due consideration given to forecasting risk. These assumptions are subject to varying degrees of judgment and complexity. Estimates of future revenue growth rates and margin assumptions represent our best estimates of future cash flows given our expectations of market growth for the security products industry in the specific markets in which we operate, as well as factors such as our market positioning, brand strength, pricing and marketing efforts and other growth and productivity opportunities and initiatives. Discount rate assumptions represent our best estimates of market participant adjusted weighted-average costs of capital. Although these assumptions represent our best estimates as of the assessment date, certain factors could potentially create variances in these estimates, including, but not limited to:

•Decreases in estimated market sizes or market growth rates due to greater than expected declines in volumes, pricing pressures or disruptive technology;

•Declines in our market share and penetration assumptions due to increased competition or an inability to develop or launch new products;

•The impacts of market volatility, including but not limited to, impacts of global pandemics, greater than expected inflation, supply chain disruption and delays, declines in pricing, reductions in volumes or fluctuations in foreign currency exchange rates;

•The level of success of on-going and future research and development efforts, including those related to acquisitions, and increases in the research and development costs necessary to obtain regulatory approvals and launch new products; and

•Volatility in market interest rates that could impact the selection of an appropriate discount rate.

The market approach requires determining an appropriate peer group, which is utilized to derive estimated fair values of our reporting units based on selected market multiples. The market approach reflects the market’s expectations for future growth and risk, with adjustments to account for differences between the selected peer group companies and the subject reporting units. While market multiples are based on observable, arm’s-length evidence of value, these assumptions are still subject to inherent uncertainty, as the peer-group companies may differ in significant ways from one or more of our reporting units in terms of size, growth or business characteristics.

The critical accounting estimates and assumptions discussed above, include our estimates of revenue growth rates and margin assumptions, discount rates, our selection of an appropriate peer group and selected market multiples. These estimates and assumptions are considered critical, as they are subject to a high degree of judgment and complexity. Forecasted revenue growth rates and margin assumptions are updated annually and often fluctuate from year to year due to a myriad of factors, such as our assessment of the macroeconomic conditions throughout the major markets in which we do business, supply chain challenges, elevated levels of inflation in recent years and pricing initiatives to offset inflation, market acceptance of new product innovation, investments in productivity projects, restructuring efforts, among other economic, strategic and operational factors impacting our businesses. Discount rate and market multiple assumptions are similarly updated annually, based on our best estimates of market participants, which typically include observable, arm's length-evidence of value, where possible. While we make every effort to estimate fair value as accurately as possible with the information available at the assessment date, changes in assumptions and estimates may affect the estimated fair value of the reporting unit and could result in impairment charges in future periods. During our most recent annual impairment analysis, none of our reporting units were determined to be impaired.

•Indefinite-lived intangible assets – Similar to goodwill, indefinite-lived intangible assets are tested annually during the fourth quarter for impairment or when there is a significant change in events or circumstances that indicate the fair value of the asset is, more likely than not, less than its carrying amount. Recoverability of indefinite-lived intangible assets is determined on a relief from royalty methodology, which is based on the implied royalty paid, at an appropriate discount rate, to license the use of an asset rather than owning the asset. The present value of the after-tax cost savings (i.e. royalty relief) indicates the estimated fair value of the asset. Any excess of the carrying value over the estimated fair value is recognized as an impairment loss equal to that excess. The critical assumptions utilized in our annual impairment analysis for indefinite-lived intangible assets include our estimates of revenue growth rate, royalty rates and discount rates, which often differ amongst our various indefinite-lived assets. We assess the appropriateness of each royalty rate assumption annually, based on our assessment of observable market royalty rates and an analysis of the profitability of the primary business that owns or otherwise uses the indefinite-lived asset. Discount rate assumptions typically consider the discount rate conclusions for the reporting unit in which an underlying business operates, plus an incremental spread, where appropriate, to consider size, country or other company-specific risk. A significant change in any or a combination of the assumptions used to estimate fair value of our indefinite-lived intangible assets could have a negative impact on the estimated fair values.

•Income taxes – We account for income taxes in accordance with ASC Topic 740. Deferred tax assets and liabilities are determined based on temporary differences between financial reporting and tax bases of assets and liabilities, applying enacted tax rates expected to be in effect for the year in which the differences are expected to reverse. We recognize future tax benefits, such as net operating losses and non-U.S. tax credits, to the extent that realizing these benefits is considered in our judgment to be more likely than not. The recoverability of our deferred tax assets, which we consider to be a critical estimate, is reviewed regularly by considering our historic profitability, projected future taxable income, timing of the reversals of existing temporary differences and the feasibility of our tax planning strategies. Where appropriate, we record a valuation allowance with respect to future tax benefits. We establish valuation allowances against the realizability of any deferred tax assets based on our consideration of all available evidence, both positive and negative, using a “more likely than not” standard. This assessment considers the nature, frequency and amount of recent losses, the duration of statutory carryforward periods and tax planning strategies. Although our assessments of the valuation and recoverability of our deferred tax assets can change given a change in facts and circumstances (such as a change in a statutory tax rate), in making such judgments and estimates, significant weight is given to evidence that can be objectively verified.

The provision for income taxes also involves a significant amount of management judgment regarding interpretation of relevant facts and laws in the jurisdictions in which we operate. Future changes in applicable laws, projected levels of taxable income and tax planning could change the effective tax rate and tax balances recorded by us. In addition, tax authorities periodically review income tax returns filed by us and can raise issues regarding our filing positions, timing and amount of income or deductions and the allocation of income among the jurisdictions in which we operate. A significant period of time may elapse between the filing of an income tax return and the ultimate resolution of an issue raised by a tax authority with respect to that return. We believe we have adequately provided for any reasonably foreseeable resolution of these matters and will adjust our estimates if significant events so dictate. To the extent that the ultimate results differ from our original or adjusted estimates, the effect will be recorded in the Provision for income taxes in the period the matter is finally resolved.

•Business combinations – The accounting for business combinations involves a considerable amount of judgment and estimation, including the identification of and fair values determined for acquired intangible assets, which typically include trade names, customer relationships and completed technologies. The determination of fair values of acquired intangible assets involves projections of future revenues and cash flows that are either discounted at an estimated discount rate or measured at an estimated royalty rate; fair values of other acquired assets and assumed liabilities, including potential contingent consideration; and the useful lives of the acquired assets. Due to the level of judgment and estimation required, in the case of significant acquisitions, we normally obtain the assistance of a third-party valuation specialist in estimating fair values of acquired tangible and intangible assets and assumed liabilities. An income approach or market approach (or both) is utilized in accordance with accepted valuation models to determine fair value. The determination of fair value of acquired assets typically requires the use of assumptions that include projections developed using historical information, internal forecasts, available industry and market data, estimates of revenue growth rates, profitability, customer attrition and discount and royalty rates, which are estimated at the time of acquisition, considering the perspective of marketplace participants. While we believe expectations and assumptions utilized for historical business combinations have been reasonable, they are inherently uncertain, and unanticipated market or macroeconomic events and circumstances occasionally do occur, and may occur in the future, which could affect the accuracy and validity of such assumptions.

The impact of future business combinations on our financial condition or results of operations may also be materially impacted by the change in or initial selection of assumptions and estimates, in addition to events and circumstances subsequent to the acquisition that are not reasonably anticipated when finalizing our purchase accounting estimates and assumptions.

Recent Accounting Pronouncements

See Note 2 to our Consolidated Financial Statements for a discussion of recently issued and adopted accounting pronouncements.

Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to fluctuations in currency exchange rates, commodity prices and interest rates which could impact our results of operations and financial condition.

Foreign Currency Exposures

We have operations throughout the world that manufacture and sell products in various international markets. As a result, we are exposed to movements in exchange rates of various currencies against the U.S. dollar as well as against other currencies throughout the world. We actively manage material currency exposures that are associated with purchases and sales and other

Table of Contents

assets and liabilities at the legal entity level; however, we do not hedge currency translation risk. We attempt to hedge exposures that cannot be naturally offset to an insignificant amount with foreign currency derivatives. Derivative instruments utilized in our hedging activities are viewed as risk management tools, involve little complexity and are not used for trading or speculative purposes. To minimize the risk of counter party non-performance, derivative instrument agreements are made only through major financial institutions with significant experience in such derivative instruments.

We evaluate our exposure to changes in currency exchange rates on our foreign currency derivatives using a sensitivity analysis. The sensitivity analysis is a measurement of the potential loss in fair value based on a percentage change in exchange rates. Based on the firmly committed currency derivative instruments in place at December 31, 2025, a hypothetical change in fair value of those derivative instruments assuming a 10% adverse change in exchange rates would result in an additional unrealized loss of approximately $4.3 million. This amount, when realized, would be partially offset by changes in the fair value of the underlying transactions.

Commodity Price Exposures

We purchase a wide range of raw material, including steel, zinc, brass and other non-ferrous metals, and are exposed to volatility in the prices of these and other commodities used in our products. We use fixed price contracts to manage this exposure where appropriate. We do not have committed commodity derivative instruments in place at December 31, 2025. However, an increase in commodity prices could result in lower gross profit.

Interest Rate Exposure

Of our total outstanding indebtedness of $2.0 billion as of December 31, 2025, approximately 90% incurs fixed-rate interest and is therefore not exposed to the risk of rising variable interest rates. However, outstanding borrowings under the Revolving Facility accrue variable rate interest at our option of (i) a Secured Overnight Financing Rate ("SOFR") plus the applicable margin or (ii) a base rate plus the applicable margin. The applicable margin ranges from 0.875% to 1.375% depending on our credit ratings. At December 31, 2025, the outstanding borrowings of $190.6 million under the Revolving Facility accrue interest at SOFR plus a margin of 1.125%, resulting in an interest rate of 4.902%. We are also exposed to the risk of rising interest rates to the extent that we fund our operations with short-term or variable-rate borrowings. We have $190.6 million outstanding and unused availability of $784.2 million under the Revolving Facility as of December 31, 2025. A hypothetical increase of 1% in the interest rate on the variable rate borrowings under our Revolving Facility would increase our interest expense over the next twelve months by $2.0 million based on the balances outstanding as of December 31, 2025. If the SOFR or other applicable base rates of the Revolving Facility increase in the future, our Interest expense could increase.

Item 9A. CONTROLS AND PROCEDURES


(a)			Evaluation of Disclosure Controls and Procedures

The Company's management, including its Chief Executive Officer and Chief Financial Officer, have conducted an evaluation of the effectiveness of the Company's disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act), as of the end of the period covered by this Annual Report on Form 10-K. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded as of December 31, 2025, that the Company's disclosure controls and procedures were effective in ensuring that information required to be disclosed by the Company in reports that it files or submits under the Exchange Act has been recorded, processed, summarized and reported, within the time periods specified in the Commission's rules and forms, and that such information has been accumulated and communicated to the Company's management including its Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.


(b)			Management's Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined under Exchange Act Rules 13a-15(f) and 15d-15(f). Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Internal control over financial reporting includes those policies and procedures that:

•pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the Company’s assets;

•provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that the Company’s receipts and expenditures are being made only in accordance with authorizations of the Company’s management and directors; and

•provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Company’s assets that could have a material effect on the financial statements.

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

Management assessed the effectiveness of our internal control over financial reporting as of December 31, 2025. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework (2013). We concluded that our internal control over financial reporting was effective as of December 31, 2025.

The effectiveness of our internal control over financial reporting has been audited by PricewaterhouseCoopers LLP, the independent registered public accounting firm, as stated in their report herein.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of Allegion plc

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Allegion plc and its subsidiaries (the "Company") as of December 31, 2025 and 2024, and the related consolidated statements of comprehensive income, of equity and of cash flows for each of the three years in the period ended December 31, 2025, including the related notes and financial statement schedule listed in the accompanying index (collectively referred to as the "consolidated financial statements"). We also have audited the Company's internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.

Basis for Opinions

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control Over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting 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 audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated

F-1

Table of Contents

financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Revenue Recognition

As described in Notes 2 and 18 to the consolidated financial statements, the Company has two principal revenue streams, tangible product sales and services and software. For the year ended December 31, 2025, the Company’s net revenues were $4,067.3 million. Net revenues are recognized based on the satisfaction of performance obligations under the terms of a contract. A performance obligation is a promise in a contract to transfer control of a distinct product or to provide a service, or a bundle of products or services, to a customer. Product sales involve contracts with a single performance obligation. Transfer of control typically occurs when goods are shipped from the Company's facilities or at other predetermined control transfer points (for instance, destination terms). Services and software offerings include inspection, maintenance and repair, aftermarket, design and installation services, as well as on-premise, software maintenance and software as a service solutions. Unlike the single performance obligation to ship a product or bundle of products, revenue related to services is recognized when the service based performance obligations are satisfied.

The principal consideration for our determination that performing procedures related to revenue recognition is a critical audit matter is the high degree of auditor effort in performing procedures and evaluating audit evidence related to the Company’s revenue recognition.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the revenue recognition process. These procedures also included, among others (i) testing the completeness, accuracy, and occurrence of revenue recognized during the year for a sample of revenue transactions by obtaining and inspecting source documents, such as purchase orders, invoices, shipping documentation, service order completion sheets and subsequent cash receipts, (ii) for certain revenue transactions, testing the issuance and settlement of invoices and credit memos, tracing transactions not settled to a detailed listing of accounts receivable, and testing the completeness and accuracy of data provided by management; and (iii) confirming a sample of outstanding customer invoice balances as of year-end and obtaining and inspecting source documents, such as subsequent cash receipts or shipping documentation, for confirmations not returned.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 – DESCRIPTION OF COMPANY AND BASIS OF PRESENTATION

Allegion plc, an Irish public limited company, and its consolidated subsidiaries ("Allegion" or "the Company") are a leading global company that provides security products and solutions that keep people and assets safe and secure in the places they live, learn, work and connect. Allegion creates peace of mind by pioneering safety and security to create a safer and more accessible world. The Company offers an extensive and versatile portfolio of security and access control products and solutions across a range of market-leading brands including CISA®, Interflex®, LCN®, Schlage®, SimonsVoss® and Von Duprin®.

Basis of presentation: The Consolidated Financial Statements were prepared in accordance with generally accepted accounting principles in the United States of America ("GAAP") as defined by the Financial Accounting Standards Board ("FASB") within the FASB Accounting Standards Codification ("ASC").

NOTE 2 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The following is a summary of significant accounting policies used in the preparation of the accompanying Consolidated Financial Statements:

Principles of Consolidation: The Consolidated Financial Statements include all controlled subsidiaries of the Company, after elimination of all intercompany accounts and transactions. A noncontrolling interest in a subsidiary is considered an ownership interest in a controlled subsidiary that is not attributable to the Company. The Company includes noncontrolling interests as a component of Total equity in the Consolidated Balance Sheets and the Net earnings attributable to noncontrolling interests are presented as an adjustment from Net earnings used to arrive at Net earnings attributable to Allegion plc in the Consolidated Statements of Comprehensive Income.

Use of Estimates: The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosures of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Estimates are based on several factors including the facts and circumstances available at the time the estimates are made, historical experience, risk of loss, general economic conditions and trends and the assessment of the probable future outcome. Some of the more significant estimates include useful lives of property, plant and equipment and intangible assets, purchase price allocations of acquired businesses, valuation of assets and liabilities including goodwill and other intangible assets, product warranties, sales allowances, assets and liabilities related to defined benefit plans, taxes, lease related assets and liabilities, share-based compensation, environmental costs, product liability and other contingencies. Actual results could differ from the Company's estimates. Estimates and assumptions are reviewed periodically, and the effects of changes, if any, are reflected in the Consolidated Statements of Comprehensive Income in the period they are determined.

Currency Translation: Assets and liabilities where the functional currency is not the U.S. dollar have been translated at year-end exchange rates, and income and expense accounts have been translated using average exchange rates throughout the year. Adjustments resulting from the process of translating a subsidiary’s financial statements into the U.S. dollar are recorded to Accumulated other comprehensive loss.

Foreign currency transaction gains and losses are a result of the effect of exchange rate changes on transactions denominated in currencies other than the functional currency. Transaction gains and losses are recognized in Other income, net, in the Consolidated Statements of Comprehensive Income in the period they are incurred.

Cash and Cash Equivalents: Cash and cash equivalents include cash on hand, demand deposits and all highly liquid investments with original maturities at the time of purchase of three months or less.

Accounts and Notes Receivable, Net: Receivables consist of billed receivables which are currently due from customers. The Company provides for an allowance for doubtful accounts and notes receivable, which represents the best estimate of expected lifetime credit losses inherent in the Company’s accounts and notes receivable portfolios. The Company's estimates are influenced by a continuing credit evaluation of customers' financial condition, trade accounts and notes receivable aging and historical loss experience, as well as reasonable and supportable forecasts of future economic conditions. The Company has reserved $12.9 million and $20.2 million for doubtful accounts and notes receivable as of December 31, 2025 and 2024, respectively.

Inventories: Inventories are stated at the lower of cost and net realizable value using the first-in, first-out (FIFO) method.

Property, Plant and Equipment: Property, plant and equipment are stated at cost, less accumulated depreciation. Assets placed in service are recorded at cost and depreciated using the straight-line method over the estimated useful life of the asset except for leasehold improvements, which are depreciated over the shorter of their economic useful life or their lease term. Repair and maintenance costs that do not extend the useful life of the asset are expensed as incurred. Major replacements and

F-7

Table of Contents

significant improvements that increase asset values and/or extend useful lives are capitalized. The range of useful lives used to depreciate property, plant and equipment is as follows:


Buildings	10	to	50	years
Machinery and equipment	2	to	12	years
Software	2	to	7	years

The Company assesses the recoverability of the carrying value of its property, plant and equipment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be fully recoverable. Recoverability is measured by a comparison of the carrying amount of an asset to the future net undiscounted cash flows expected to be generated by the asset. If the undiscounted cash flows are less than the carrying amount of the asset, an impairment loss is recognized for the amount by which the carrying value of the asset exceeds its fair value.

Investments: The Company periodically invests in debt or equity securities of start-up companies and/or development stage technology or other companies without acquiring a controlling interest. The Company applies the equity method of accounting when the Company has the ability to exercise significant influence over the operating and financial decision making of the investee. Investments in equity method affiliates totaled $15.5 million and $13.7 million as of December 31, 2025 and 2024, respectively. Equity investments that have readily determinable fair values in which the Company does not have significant influence are measured at fair value, with any unrealized holding gains and losses being recorded to earnings. Investments without readily determinable fair values are measured at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or similar investment of the same issuer and are qualitatively assessed for impairment indicators each reporting period. Investments in debt and equity securities not accounted for under the equity method of accounting totaled $66.8 million and $66.9 million as of December 31, 2025 and 2024, respectively. The Company's investments are recorded within Other noncurrent assets within the Consolidated Balance Sheets.

Leases: As a lessee, the Company categorizes its leases into two general categories: real estate and equipment leases. The Company's real estate leases include leased production and assembly facilities, warehouses and distribution centers and office space, while the Company's equipment leases primarily include vehicles, material handling and other equipment utilized in the Company's facilities, laptops and other information technology ("IT") equipment. The Company records a right-of-use ("ROU") asset and lease liability for substantially all leases for which it is a lessee. At inception of a contract, the Company considers all relevant facts and circumstances to assess whether or not the contract represents a lease by determining whether or not the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. The Company assesses the specific terms and conditions of each lease to determine the appropriate classification as either an operating or finance lease and the lease term. Substantially all of the Company's leases for which the Company is a lessee are classified as operating leases. If at lease commencement date, a lease has a term of less than 12 months and does not include a purchase option that is reasonably certain to be exercised, the Company does not include the lease as part of its ROU asset or lease liability. If the Company enters into a large number of leases in the same month with the same terms and conditions, these are considered a group (portfolio). There are no material residual value guarantees provided by the Company nor any restrictions or covenants imposed by any leases to which the Company is a party.

The Company assesses the specific terms and conditions of each real estate lease, which can vary significantly from lease to lease, to determine the amount of the lease payments and the length of the lease term, which includes the minimum period over which lease payments are required plus any renewal options that are both within the Company's control to exercise and reasonably certain of being exercised upon lease commencement. When available, the Company will utilize the rate implicit in the lease as the discount rate to determine the lease liability; however, as this rate is not available for most leases, the Company will use its incremental borrowing rate for debt instruments with terms approximating the weighted-average term of its real estate or equipment leases to discount the future lease payments over the lease term to present value. The Company incurs variable lease payments for certain of its real estate leases, such as reimbursements of property taxes, maintenance and other operational costs to the lessor. In general, these variable lease payments are not captured as part of the lease liability or ROU asset, but rather are expensed as incurred. Most of the Company's equipment leases are for terms ranging from two to five years, although terms and conditions can vary from lease to lease. The Company applies similar estimates and judgments to its equipment lease portfolio in determining the lease payments, lease term and incremental borrowing rate as it does to its real estate lease portfolio. The Company does not typically incur variable lease payments related to its equipment leases.

Goodwill: The Company records goodwill as the excess of the purchase price of an acquired business over the fair value of the net assets acquired. Goodwill is tested and reviewed annually for impairment during the fourth quarter or whenever there is a significant change in events or circumstances that indicate the fair value of a reporting unit is more likely than not less than its carrying amount. Recoverability of goodwill is measured at the reporting unit level. The carrying amount of a reporting unit is compared to its estimated fair value. If the estimated fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is not impaired. To the extent that the carrying value of the reporting unit exceeds its estimated fair value, a goodwill impairment charge will be recognized for the amount by which the carrying value of the reporting unit exceeds its fair

F-8

Table of Contents

value, not to exceed the carrying amount of the reporting unit's goodwill. Estimated fair value of the Company's reporting units is based on two valuation techniques, a discounted cash flow model (income approach) and a market multiple of earnings (market approach), with each method being weighted in the calculation.

Intangible Assets: Similar to Goodwill, indefinite-lived intangible assets are not amortized, but are tested and reviewed annually for impairment during the fourth quarter or whenever there is a significant change in events or circumstances that indicate the fair value of the asset is more likely than not less than its carrying amount. Recoverability of indefinite-lived intangible assets (i.e. Trade names) is determined on a relief from royalty methodology, which is based on the implied royalty paid, at an appropriate discount rate, to license the use of an asset rather than owning the asset. The present value of the after-tax cost savings (i.e. royalty relief) indicates the estimated fair value of the asset. Any excess of the carrying value over the estimated fair value is recognized as an impairment loss equal to that excess.

Intangible assets such as completed technologies, patents, customer-related intangible assets and other intangible assets with finite useful lives are amortized on a straight-line basis over their estimated economic lives. The weighted-average useful lives approximate the following:


Customer relationships	21	years
Trade names (finite-lived)	14	years
Completed technologies/patents	11	years
Other	5	years

Recoverability of intangible assets with finite useful lives is assessed in the same manner as property, plant and equipment, as described above.

Business Combinations: The fair value of consideration paid in a business combination is allocated to the tangible and identifiable intangible assets acquired, liabilities assumed and goodwill using the acquisition method of accounting. Acquired intangible assets typically include trade names, customer relationships and completed technologies. The accounting for business combinations involves a considerable amount of judgment and estimation, and as a result, for significant acquisitions the Company normally obtains the assistance of a third-party valuation specialist in estimating fair values of acquired tangible and intangible assets and assumed liabilities. The allocation of consideration paid to assets acquired and liabilities assumed may be subject to revision based on the final determination of fair values during the measurement period, which may be up to one year from the acquisition date. Any contingent consideration is recorded at the estimated fair value as of the date of the acquisition and is recorded as part of the purchase price. This estimate is updated in future periods and any changes in the estimate, which are not considered an adjustment to the purchase price, are recorded in the Consolidated Statements of Comprehensive Income. Business acquisition and integration costs are expensed as incurred.

Income Taxes: The calculation of the Company’s income taxes involves considerable judgment and the use of both estimates and allocations. Deferred tax assets and liabilities are determined based on temporary differences between financial reporting and tax bases of assets and liabilities, applying enacted tax rates expected to be in effect for the year in which the differences are expected to reverse. The Company recognizes future tax benefits, such as net operating losses and tax credits, to the extent that realizing these benefits is considered in its judgment to be more likely than not. The Company regularly reviews the recoverability of its deferred tax assets considering its historic profitability, projected future taxable income, timing of the reversals of existing temporary differences and the feasibility of its tax planning strategies. Where appropriate, the Company records a valuation allowance with respect to future tax benefits.

Cash paid for income taxes, net of refunds, for the year ended December 31, 2025, was $121.2 million. Irish federal taxes paid were $1.3 million, U.S. federal taxes paid were $72.5 million and other foreign taxes paid were $47.4 million. Cash paid for income taxes, net of refunds, for the years ended December 31, 2024 and 2023 was $158.3 million and $157.9 million, respectively. The reduction in cash taxes paid in 2025 compared to prior years was primarily attributable to the 2025 enactment of the One Big Beautiful Bill Act in the United States, which allowed for the acceleration of certain tax deductions.

Product Warranties: The Company offers a standard warranty with most product sales, and the value of such warranty is included in the contractual sales price. Standard product warranty accruals are recorded at the time of sale and are estimated based upon product warranty terms and historical experience. The Company regularly assesses the adequacy of its liabilities and makes adjustments as necessary based on known or anticipated warranty claims, or as new information becomes available.

Revenue Recognition: Net revenues are recognized based on the satisfaction of performance obligations under the terms of a contract. A performance obligation is a promise in a contract to transfer control of a distinct product or to provide a service, or a bundle of products or services, to a customer. The Company has two principal revenue streams, tangible product sales and services and software. Product sales involve contracts with a single performance obligation, the transfer of control of a product or bundle of products to a customer. Transfer of control typically occurs when goods are shipped from the Company's facilities or at other predetermined control transfer points (for instance, destination terms). Services and software offerings include inspection, maintenance and repair, aftermarket, design and installation services, as well as on-premise, software maintenance and software as a service ("SaaS") solutions. Unlike the single performance obligation to ship a product or bundle of products,

F-9

Table of Contents

revenue related to services is recognized when the service based performance obligations are satisfied. In some instances, customer acceptance provisions are included in sales arrangements to give the buyer the ability to ensure the service meets any established criteria. In these instances, revenue recognition is deferred until the performance obligations are satisfied, which could include acceptance terms specified in the arrangement being fulfilled through customer acceptance or a demonstration that established criteria have been satisfied. Revenue from on-premise software solutions are recognized at the point in time when the customer can benefit from the software, which generally aligns with the beginning of the license period.

Net revenues are measured as the amount of consideration expected to be received in exchange for transferring control of the products or providing the services and takes into account variable consideration, such as sales incentive programs including discounts and volume rebates. The existence of these programs does not preclude revenue recognition but does require the Company's best estimate of the variable consideration to be made based on expected activity, as these items are reserved for as a deduction to Net revenues based on the Company's historical rates of providing these incentives and annual forecasted sales volumes. Sales returns and customer disputes involving a question of quantity or price are accounted for as variable consideration, and therefore, as a reduction to Net revenues and as a contra receivable. At December 31, 2025 and 2024, the Company had a reserve for customer claims of $50.6 million and $56.2 million, respectively. All other incentives or incentive programs where the customer is required to reach a certain level of purchases, remain a customer for a certain period, provide a rebate form or is subject to additional requirements are also considered variable consideration and are accounted for as a reduction of revenue and a liability. At December 31, 2025 and 2024, the Company had a sales incentive accrual of $73.5 million and $62.8 million, respectively. These estimates are reviewed regularly for accuracy, and if updated information or actual amounts are different from previous estimates, the revisions are included in the Company’s results for the period in which they become known.

As a practical expedient allowed under ASC 606, "Revenue from Contracts with Customers", the Company recognizes incremental costs of obtaining a contract, if any, as an expense when incurred if the amortization period of the asset would have been one year or less. The Company also applies the practical expedients to omit the disclosure of remaining performance obligations for contracts with an original expected duration of one year or less. The transaction price is not adjusted for the effects of a significant financing component, as the time period between control transfer of goods and services is less than one year. Sales, value-added and other similar taxes collected by the Company are excluded from Net revenues. The Company has also elected to account for shipping and handling activities that occur after control of the related goods transfers as fulfillment activities instead of performance obligations. These activities are included in Cost of goods sold in the Consolidated Statements of Comprehensive Income. The Company’s payment terms are generally consistent with the industries in which its businesses operate.

Environmental Costs: The Company is subject to laws and regulations relating to protecting the environment and is dedicated to an environmental program to reduce the utilization and generation of hazardous materials during the manufacturing process and to remediate identified environmental concerns. The Company is currently engaged in site investigations and remediation activities to address environmental cleanup from past operations at current and former production facilities. The Company is also sometimes a party to environmental lawsuits and claims and has, from time to time, received notices of potential violations of environmental laws and regulations from the U.S. Environmental Protection Agency and similar state authorities. It has also been identified as a potentially responsible party ("PRP") for cleanup costs associated with off-site waste disposal at federal Superfund and state remediation sites for past operations. For all such sites, there are other PRPs and, in most instances, the Company’s involvement is minimal. In estimating its liability, the Company has assumed it will not bear the entire cost of remediation of any site to the exclusion of other PRPs who may be jointly and severally liable. The ability of other PRPs to participate has been taken into account, based on the Company's understanding of the parties’ financial condition and probable contributions on a per site basis. The Company regularly evaluates its remediation programs and considers alternative remediation methods that are in addition to, or in replacement of, those currently utilized by the Company based upon enhanced technology and regulatory changes.

Environmental expenditures relating to current operations are expensed or capitalized as appropriate. Expenditures relating to existing conditions caused by past operations, which do not contribute to current or future revenues, are expensed. Liabilities for remediation costs are recorded when they are probable and can be reasonably estimated, generally no later than the completion of feasibility studies or the Company’s commitment to a plan of action. The assessment of this liability, which is calculated based on existing technology, does not reflect any offset for possible recoveries from insurance companies and is not discounted.

Research and Development Costs: The Company conducts research and development activities for the purpose of developing and improving new products and services. These costs are expensed when incurred. For the years ended December 31, 2025, 2024 and 2023, expenses related to research and development activities amounted to approximately $132.0 million, $112.7 million and $101.9 million, respectively, and primarily consisted of salaries, wages, benefits, facility costs and other overhead expenses.

Defined Benefit Plans: The Company provides a range of U.S. and non-U.S. defined benefit plan benefits to eligible current and former employees. Noncontributory defined benefit pension plans covering non-collectively bargained U.S. employees provide benefits based on an average pay formula while most plans for collectively bargained U.S. employees provide benefits based on a flat dollar benefit formula. The non-U.S. defined benefit plans generally provide benefits based on earnings and years of service. Determining the costs associated with such benefits is dependent on various actuarial assumptions, including discount rates, expected returns on plan assets, employee mortality and turnover rates. Actuarial valuations are performed to determine the plan obligations and expense in accordance with GAAP. Actual results may differ from the actuarial estimates and assumptions, and when they do, are generally recorded to Accumulated other comprehensive loss and amortized into Net earnings over future periods.

The Company reviews its actuarial assumptions at each measurement date and makes modifications to the assumptions as appropriate. Discount rates are generally established using hypothetical yield curves based on the yields of corporate bonds rated AA quality. Spot rates are developed from the yield curve and used to discount future benefit payments. The expected return on plan assets reflects the average rate of returns expected on the funds invested or to be invested to provide for the benefits included in the projected benefit obligation. The expected return on plan assets is based on what is achievable given the plan’s investment policy, the types of assets held and the target asset allocation.

Share-Based Compensation: The Company records share-based compensation awards using a fair value method and recognizes compensation expense for an amount equal to the fair value of the share-based payment award issued. The Company’s share-based compensation plans include programs for stock options, restricted stock units ("RSUs"), performance stock units ("PSUs") and deferred compensation. The fair value of each of the Company’s stock option and RSU awards is expensed on a straight-line basis over the required service period, which is generally the 3-year vesting period. However, for stock options and RSUs granted to retirement eligible employees, the Company recognizes expense for the fair value of these awards at the grant date. The Company's Performance Stock Program ("PSP") provides awards for key employees in the form of PSUs based on performance against pre-established objectives. The annual target award level is expressed as a number of the Company's ordinary shares. All PSUs are settled in the form of ordinary shares.

Share Repurchases: Common shares that are repurchased by the Company subsequent to issuance are immediately retired upon settlement and decrease the total number of shares issued and outstanding. The cost of share repurchases is charged against shareholder's equity.

Loss Contingencies: Liabilities are recorded for various contingencies arising in the normal course of business, including litigation and administrative proceedings, environmental matters, product liabilities, product warranties, workers' compensation and other claims. The Company has recorded reserves in the financial statements related to these matters, which are developed using inputs derived from actuarial estimates and historical and anticipated experience data, depending on the nature of the reserve and, in certain instances, with consultation of legal counsel, internal and external consultants and engineers. Amounts recorded for identified contingent liabilities are estimates, which are reviewed periodically and adjusted to reflect additional information when it becomes available.

Financial Instruments: The Company uses various financial instruments, including derivative instruments, to manage the risks associated with interest and currency rate exposures. These financial instruments are not used for trading or speculative purposes. When a derivative contract is entered into, the Company designates the derivative instrument as a cash flow hedge of a forecasted transaction, a cash flow hedge of a recognized asset or liability or as an undesignated derivative. The Company formally documents its hedge relationships, including identification of the derivative instruments and the hedged items, as well as its risk management objectives and strategies for undertaking the hedge transaction. This process includes linking derivative instruments that are designated as hedges to specific assets, liabilities or forecasted transactions.

The Company assesses at inception and at least quarterly thereafter, whether the derivatives used in cash flow hedging transactions are effective in offsetting the changes in the cash flows of the hedged item. To the extent the derivative is deemed to be an effective hedge, the fair market value changes of the instrument are recorded to Accumulated other comprehensive loss and subsequently reclassified to Net earnings when the hedged transaction affects earnings. Changes in the fair market value of derivatives not deemed to be an effective hedge are recorded in Net earnings in the period of change. The Company recognizes all derivative instruments on the Consolidated Balance Sheets at their fair value, which is determined through market-based valuations and may not be representative of the actual gains or losses that will be recorded when these instruments mature due to future fluctuations in the markets in which they are traded. If the hedging relationship ceases to be effective subsequent to inception, or it becomes probable that a forecasted transaction will no longer occur, the hedging relationship will be undesignated, and any future gains or losses on the derivative instrument will be recorded in Net earnings.

On December 9, 2025, the Company amended and restated its unsecured revolving credit facility (the "Revolving Facility") which, among other things, increased the total commitment from $750.0 million to $1.0 billion, and extended the maturity from May 20, 2029 to May 20, 2030. The Company used borrowings under the Revolving Facility to repay its outstanding term loan, which was scheduled to mature in November 2026. Outstanding borrowings under the Revolving Facility were $190.6 million at December 31, 2025.

The Revolving Facility provides aggregate commitments of up to $1.0 billion, which includes up to $100.0 million for the issuance of letters of credit. The Company had $25.2 million and $18.4 million of letters of credit outstanding at December 31, 2025 and 2024, respectively. Borrowings under the Revolving Facility may be repaid at any time without premium or penalty, and amounts repaid may be reborrowed. The Company pays certain fees with respect to the Revolving Facility, including an unused commitment fee on the undrawn portion of between 0.080% and 0.200% per year, depending on the Company's credit ratings, as well as certain other fees.

Outstanding borrowings under the Revolving Facility accrue interest, at the option of the Company, of (i) a SOFR plus an applicable margin, or (ii) a base rate (as defined in the credit agreement) plus an applicable margin. The applicable margin ranges from 0.875% to 1.375% depending on the Company's credit ratings. At December 31, 2025, the Company's outstanding borrowings under the Revolving Facility accrued interest at SOFR plus a margin of 1.125%, resulting in an interest rate of 4.902%. The credit agreement also contains negative and affirmative covenants and events of default that, among other things, limit or restrict the Company’s ability to enter into certain transactions. In addition, the Revolving Facility requires the Company to comply with a maximum leverage ratio as defined in the credit agreement. As of December 31, 2025, the Company was in compliance with all applicable covenants under the credit agreement.

Senior Notes

As of December 31, 2025, Allegion US Hold Co has $400.0 million outstanding of its 3.550% Senior Notes due 2027 (the “3.550% Senior Notes”), $600.0 million outstanding of its 5.411% Senior Notes due 2032 (the “5.411% Senior Notes”) and $400.0 million outstanding of its 5.600% Senior Notes due 2034 (the "5.600% Senior Notes"), and Allegion plc has $400.0 million outstanding of its 3.500% Senior Notes due 2029 (the “3.500% Senior Notes”, and all four senior notes collectively, the "Senior Notes"). The 3.550% Senior Notes and 3.500% Senior Notes both require semi-annual interest payments on April 1 and October 1 of each year and mature on October 1, 2027 and October 1, 2029, respectively. The 5.411% Senior Notes require semi-annual interest payments on January 1 and July 1 of each year and mature on July 1, 2032. The 5.600% Senior Notes require semi-annual interest payments on May 29 and November 29 of each year and mature on May 29, 2034.

The 3.550% Senior Notes, 5.411% Senior Notes and 5.600% Senior Notes are senior unsecured obligations of Allegion US Hold Co and rank equally with all of Allegion US Hold Co’s existing and future senior unsecured and unsubordinated indebtedness. The guarantee of the 3.550% Senior Notes, 5.411% Senior Notes and 5.600% Senior Notes is the senior unsecured obligation of Allegion plc and ranks equally with all of the Company's existing and future senior unsecured and unsubordinated indebtedness. The 3.500% Senior Notes are senior unsecured obligations of Allegion plc, are guaranteed by Allegion US Hold Co and rank equally with all of the Company's existing and future senior unsecured indebtedness.

NOTE 9 – FINANCIAL INSTRUMENTS

Currency Hedging Instruments

The gross notional amount of the Company’s currency derivatives was $320.1 million and $167.2 million at December 31, 2025 and 2024, respectively. Neither the fair values of currency derivatives, which are determined based on a pricing model that uses spot rates and forward prices from actively quoted currency markets that are readily observable (Level 2 inputs under the fair value hierarchy described in Note 12), nor the balances included in Accumulated other comprehensive loss, were material as of December 31, 2025 and 2024. Currency derivatives designated as cash flow hedges did not have a material impact to either Net earnings or Other comprehensive income (loss) during any of the years ended December 31, 2025, 2024 or 2023, nor is the amount to be reclassified into Net earnings over the next twelve months expected to be material, although the actual amounts that will be reclassified to Net earnings may vary as a result of future changes in market conditions. At December 31, 2025, the maximum term of the Company's currency derivatives, both those that are designated as cash flow hedges and those that are not, was less than one year.

Concentration of Credit Risk

The counterparties to the Company’s forward contracts consist of a number of investment grade major international financial institutions. The Company could be exposed to losses in the event of nonperformance by the counterparties. However, the credit ratings and the concentration of risk in these financial institutions are monitored on a continuous basis and present no significant credit risk to the Company.

It is the Company’s objective to contribute to the pension plans to ensure adequate funds are available in the plans to make benefit payments to plan participants and beneficiaries when required. However, certain plans are not funded due to either legal, accounting or tax requirements in certain jurisdictions. As of December 31, 2025, approximately 6% of the Company's projected benefit obligation relates to plans that are not funded, of which the majority are non-U.S. plans.

Net periodic pension benefit cost for 2026 is projected to be approximately $3.6 million, utilizing the assumptions for calculating the pension benefit obligations at the end of 2025.

Weighted-average assumptions utilized in determining net periodic pension benefit cost for the years ended December 31, were as follows:


	2025		2024		2023
Discount rate:
U.S. plans	5.6	%	5.1	%	5.4	%

Expected return on plan assets:
U.S. plans	7.0	%	6.5	%	6.5	%
Non-U.S. plans	6.9	%	6.2	%	6.4	%

The Company generally estimates the service and interest cost components of net periodic benefit cost utilizing a full yield-curve approach. Under this approach, the Company applies discounting using the applicable spot rates derived from the yield curve to discount the cash flows used to measure the benefit obligation. These spot rates align to each of the projected benefit obligation cash flows and service cost cash flows. The expected return on plan assets reflects the average rate of returns expected on the funds invested or to be invested to provide for the benefits included in the projected benefit obligation and is based on what is achievable given the plan’s investment policy, the types of assets held and target asset allocations. The expected long-term rate of return is determined as of the measurement date. Each plan is reviewed, along with its historical returns and target asset allocations, to determine the appropriate expected return on plan assets to be used.

The Company's overall objective in managing its defined benefit plan assets is to ensure that all present and future benefit obligations are met as they come due. The goal is to achieve this while trying to mitigate volatility in plan funded status, contributions and expense by better matching the characteristics of the plan assets to that of the plan liabilities. Each plan’s funded status and asset allocation is monitored regularly in addition to investment manager performance.

Table of Contents

The Company's non-U.S. pension plan assets are valued using the following methodologies:

•Cash, cash equivalents and short-term investments – Cash equivalents are valued using a market approach with inputs including quoted market prices for either identical or similar instruments. Short-term investments are valued at the closing price or amount held on deposit by the custodian bank, at fair value by discounting the related cash flows based on current yields of similar instruments with comparable durations considering the credit-worthiness of the issuer, or at NAV per share or the equivalent based upon the fair value of the underlying investments. NAV per share or the equivalent is used for fair value purposes as a practical expedient and is calculated by the investment manager or sponsor of the fund. These investments primarily consist of short-term investment funds.

•Equity mutual funds – Equity mutual funds are primarily valued at NAV per share or the equivalent. NAV per share or the equivalent is used for fair value purposes as a practical expedient and is calculated by the investment manager or sponsor of the fund.

•Corporate and non-U.S. bonds – Quoted market prices are not available for these securities. Fair values are either estimated using pricing models and/or quoted prices of securities with similar characteristics or discounted cash flows, in which instances such securities are classified as Level 2, or valued at NAV per share or the equivalent. NAV per share or the equivalent is used for fair value purposes as a practical expedient and is calculated by the investment manager or sponsor of the fund.

The Company made employer contributions of $0.1 million, $0.2 million and $15.9 million to the U.S. pension plans in 2025, 2024 and 2023, respectively. The Company made employer contributions to its non-U.S. pension plans of $4.7 million, $5.0 million and $5.0 million in 2025, 2024 and 2023, respectively.

The Company currently projects that approximately $3.9 million will be contributed to its plans worldwide in 2026. The Company’s policy allows it to fund an amount, which could be in excess of or less than the pension cost expensed, subject to the limitations imposed by current tax regulations. The Company anticipates funding the plans in 2026 in accordance with contributions required by funding regulations or the laws of each jurisdiction.

Most of the Company’s U.S. employees are covered by defined contribution plans. Employer contributions are determined based on criteria specific to the individual plans and amounted to approximately $36.2 million, $33.0 million and $31.7 million in 2025, 2024 and 2023, respectively. The Company’s contributions relating to non-U.S. defined contribution plans and other non-U.S. benefit plans were $12.0 million, $10.9 million and $10.1 million in 2025, 2024 and 2023, respectively.

Deferred Compensation Plan

The Company maintains an Executive Deferred Compensation Plan, which is an unfunded, nonqualified plan that, prior to 2019, permitted certain employees to defer up to 50% of their annual salary and up to 100% of their annual bonus awards, performance stock plan awards and restricted stock units into a number of investment choices, including its ordinary share equivalents, until conclusion of their employment with the Company. As of December 31, 2025 and 2024, the deferred compensation liability balance was $11.5 million and $12.0 million, respectively, the majority of which was recorded within Postemployment and other benefit liabilities in the Consolidated Balance Sheets. Amounts invested in ordinary share equivalents of the Company are not included in the deferred compensation liability balance, as these amounts will be settled in ordinary shares of the Company at the time of distribution.

NOTE 12 – FAIR VALUE MEASUREMENTS

Fair value is defined as the exchange price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Fair value measurements are based on a framework that utilizes the inputs market participants use to determine the fair value of an asset or liability and establishes a fair value hierarchy to prioritize those inputs. The fair value hierarchy is comprised of the three levels described below:

•Level 1 – Inputs based on quoted prices in active markets for identical assets or liabilities.

•Level 2 – Inputs other than Level 1 quoted prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability.

•Level 3 – Unobservable inputs based on little or no market activity and that are significant to the fair value of the assets and liabilities.

The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Observable inputs are obtained from independent sources and can be validated by a third party, whereas unobservable inputs reflect assumptions regarding what a third party would use in pricing an asset or liability based on the best information available under the circumstances. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement.

The Company determines the fair value of its financial assets and liabilities using the following methodologies:

•Investments – These instruments include equity mutual funds and corporate bond funds. The fair value is obtained based on observable market prices quoted on public exchanges for similar instruments.

•Deferred compensation and other retirement plans – These include obligations related to deferred compensation and other retirement plans adjusted for market performance. The fair value is obtained based on observable market prices quoted on public exchanges for similar instruments.

•Debt – These instruments are recorded at cost and include the Revolving Facility and Senior Notes maturing through 2034. The fair value of these debt instruments is obtained based on observable market prices quoted on public exchanges for similar instruments.

The carrying values of Cash and cash equivalents, Accounts and notes receivable, net, Accounts payable, Accrued compensation and benefits and Accrued expenses and other current liabilities are a reasonable estimate of their fair values due to the short-term nature of these instruments. As discussed in Note 2, the Company also has investments in debt and equity securities without readily determinable fair values, which are measured at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for identical or similar investments of the same issuer and are qualitatively assessed for impairment indicators at each reporting period. As these investments are considered to be nonrecurring fair value measurements, they are not included in the fair value tables above.

The methodologies used by the Company to determine the fair value of its financial assets and liabilities at December 31, 2025, are the same as those used at December 31, 2024.

Stock Options / RSUs

The weighted-average fair value of stock options granted for the years ended December 31, 2025, 2024 and 2023, was estimated to be $37.72, $40.92 and $33.66 per share, respectively, using the Black-Scholes option-pricing model. The weighted-average assumptions used were as follows:


	2025		2024		2023
Dividend yield	1.61	%	1.47	%	1.60	%
Volatility	29.89	%	29.28	%	28.47	%
Risk-free rate of return	4.31	%	4.29	%	4.10	%
Expected life	5.4 years		6.0 years		6.0 years

Volatility is based on the Company's historic volatility. The risk-free rate of return is based on the yield curve of a zero-coupon U.S. Treasury bond on the date the award is granted with a maturity equal to the expected term of the award. In 2023 and 2024, the expected life of the Company’s stock option awards was derived from the simplified approach based on the weighted-average time to vest and the remaining contractual term, because the company did not have sufficient history to estimate expected life. Beginning in 2025, the expected life of the Company's stock option awards is derived from historical data, based on the past exercise activity and post-vest cancellation activity of the Company's stock option program and represents the period of time that awards are expected to be outstanding.

Changes in options outstanding under the plans for the years ended December 31, 2025, 2024 and 2023, were as follows:


	Shares subject to option	Weighted- average exercise price(a)		Aggregate intrinsic value (millions)		Weighted-average remaining life (years)

At December 31, 2025, there was $4.3 million of total unrecognized compensation cost from stock option arrangements granted under the plan, which is primarily related to unvested stock options held by non-retirement eligible employees. The aggregate intrinsic value of stock options exercised during the years ended December 31, 2025 and 2024, was $16.2 million and $11.4 million, respectively. Generally, stock options expire ten years from their date of grant.

Performance Stock

In February 2023, 2024 and 2025, the Compensation Committee of the Company's Board of Directors granted PSUs that vested based 50% upon a performance condition, measured at each reporting period by earnings per share ("EPS") performance during a three-year performance period in relation to pre-established targets set by the Compensation Committee, and 50% upon a market condition, measured by the Company’s relative total shareholder return ("TSR") against, for 2023, the S&P 400 Capital Goods Index over a three-year performance period, and for 2024 and 2025, a 50/50 weighting of the S&P 400 Capitals Goods Index and the S&P 500 Capital Goods Index over a three-year performance period. The fair values of the market conditions are estimated using a Monte Carlo simulation approach in a risk-neutral framework to model future stock price movements based upon historical volatility, risk-free rates of return and correlation matrix.

The following table summarizes PSU activity for the maximum number of shares that may be issued upon vesting of those awards for the years ended December 31, 2025, 2024 and 2023:

(a)The weighted-average grant date fair value represents the fair value of the awards on the grant date converted to ordinary shares of the Company.

At December 31, 2025, there was $8.6 million of total unrecognized compensation cost from the PSP based on actual performance through such date, which is related to shares underlying unvested awards. This compensation cost will be recognized over the required service period, which is generally the three-year performance/vesting period.

The majority of the Company's earnings are considered permanently reinvested, and therefore, the Company has not recorded any incremental withholding or income tax liabilities on these permanently reinvested earnings.

At December 31, a summary of the deferred tax accounts was as follows:

At December 31, 2025, $6.1 million of deferred taxes were recorded for certain undistributed earnings of subsidiaries. Historically, no deferred taxes have been provided for any portion of the remaining undistributed earnings of the Company's subsidiaries since these earnings have been, and will continue to be, permanently reinvested in these subsidiaries. For many reasons, including the number of legal entities and jurisdictions involved, the complexity of the Company's legal entity structure, the complexity of tax laws in the relevant jurisdictions and the impact of projections of income for future years to any calculations, the Company believes it is not practicable to estimate, within any reasonable range, the amount of additional taxes which may be payable upon the distribution of earnings.

At December 31, 2025, the Company had the following tax losses and tax credit carryforwards available to offset taxable income in prior and future years:


In millions	Amount		Expiration Period
Ireland Federal tax loss carryforwards	$	67.7	Unlimited



Non-Ireland Federal and State credit carryforwards	5.2		2026-2037
Non-Ireland tax loss carryforwards	$	1,016.8	2026-Unlimited

The non-Ireland tax loss carryforwards were incurred in various jurisdictions, predominantly in Luxembourg and the United Kingdom.

The Company evaluates its deferred income tax assets to determine if valuation allowances are required or should be adjusted. GAAP requires that companies assess whether valuation allowances should be established against their deferred tax assets based on consideration of all available evidence, both positive and negative, using a "more likely than not" standard. This assessment considers the nature, frequency and amount of recent losses, the duration of statutory carryforward periods and tax planning strategies. In making such judgments, significant weight is given to evidence that can be objectively verified.

Activity associated with the Company’s valuation allowance is as follows:


In millions	2025		2024		2023
Beginning balance	$	247.0	$	281.0	$	264.7
Increase to valuation allowance	10.9		2.9		15.7
Decrease to valuation allowance	(5.9)		(26.5)		—
Tax rate change	1.2		(8.8)		—
Currency translation	2.6		(1.6)		0.6



Ending balance	$	255.8	$	247.0	$	281.0

During the year ended December 31, 2025, the valuation allowance increased by $8.8 million, while during the year ended December 31, 2024, the valuation allowance decreased by $34.0 million. The Company's valuation allowance will fluctuate from year to year as a result of changes in country specific tax laws, internal restructurings, jurisdictional profitability and changes in judgments and facts regarding the realizability of deferred tax assets.

The Company has total unrecognized tax benefits of $54.8 million and $44.5 million as of December 31, 2025 and 2024, respectively. The amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate is $54.8 million as of December 31, 2025. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:


In millions	2025		2024		2023

The Company records interest and penalties associated with the uncertain tax positions within its provision for income taxes. The Company had reserves associated with interest and penalties, net of tax, of $12.0 million and $9.2 million at December 31, 2025 and 2024, respectively. For the year ended December 31, 2025, the Company recognized $2.0 million in interest and penalties, net of tax, related to these uncertain tax positions. For the year ended December 31, 2024, the Company recognized $1.0 million in interest and penalties, net of tax, related to these uncertain tax positions.

The provision for income taxes involves a significant amount of management judgment regarding interpretation of relevant facts and laws in the jurisdictions in which the Company operates. Future changes in applicable laws, projected levels of taxable income and tax planning could change the effective tax rate and tax balances recorded by the Company. In addition, tax authorities periodically review income tax returns filed by the Company and can raise issues regarding its filing positions, timing and amount of income or deductions and the allocation of income among the jurisdictions in which the Company operates. A significant period of time may elapse between the filing of an income tax return and the ultimate resolution of an issue raised by a tax authority with respect to that return. In the normal course of business, the Company is subject to examination by taxing authorities throughout the world, including such major jurisdictions as Australia, Canada, France, Germany, Italy, Mexico, the Netherlands, Poland and the U.S. In general, the examination of the material tax returns of subsidiaries of the Company is complete for the years prior to 2016, with certain matters being resolved through appeals and litigation.

NOTE 17 – EARNINGS PER SHARE (EPS)

Basic EPS is calculated by dividing Net earnings attributable to Allegion plc by the weighted-average number of ordinary shares outstanding for the applicable period. Diluted EPS is calculated after adjusting the denominator of the basic EPS calculation for the effect of all potentially dilutive ordinary shares, which in the Company’s case, includes shares issuable under its share-based compensation plans.

F-32

Table of Contents

The following table summarizes the weighted-average number of ordinary shares outstanding for basic and diluted earnings per share calculations:


In millions	2025	2024	2023
Weighted-average number of basic shares	86.1	87.2	87.9
Shares issuable under share-based compensation plans	0.5	0.4	0.4
Weighted-average number of diluted shares	86.6	87.6	88.3

As of December 31, 2025 and 2024, 0.2 million and 0.1 million stock options were excluded from the computation of weighted-average diluted shares outstanding, respectively, because the effect of including these shares would have been anti-dilutive.

NOTE 19 – COMMITMENTS AND CONTINGENCIES

The Company is involved in various litigation, claims and administrative proceedings, including those related to environmental and product warranty matters. Amounts recorded for identified contingent liabilities are estimates, which are reviewed periodically and adjusted to reflect additional information when it becomes available. Subject to the uncertainties inherent in estimating future costs for contingent liabilities, except as expressly set forth in this note, management believes that any liability which may result from these legal matters would not have a material adverse effect on the financial condition, results of operations, liquidity or cash flows of the Company.

NOTE 20 – BUSINESS SEGMENT INFORMATION

The Company classifies its business into the following two reportable segments based on industry and market focus: Allegion Americas and Allegion International. The Company largely evaluates performance based on Segment operating income and Segment operating margin. The Company’s CODM is its chief executive officer, who uses Segment operating income as the measure of profit and loss to evaluate the financial performance of the business and as the basis for resource allocation, performance reviews and compensation. For these reasons, the Company believes Segment operating income represents the most relevant measure of segment profit and loss. The Company’s CODM may exclude certain charges or gains, such as corporate charges and other special charges, from Operating income to arrive at a Segment operating income that is a more meaningful measure of profit and loss upon which to base operating decisions. The Company defines Segment operating margin as Segment operating income as a percentage of the segment's Net revenues.
