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 create peace of mind by pioneering safety and security with a vision of enabling seamless access and a safer world. Seamless access allows authorized, automated and safe passage and movement through spaces and places in the most efficient and frictionless manner possible. Central to our vision is partnering and developing ecosystems to create a flawless experience and enable 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 across the globe deliver high-quality security 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.

Access control security 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 increasing adoption of the Internet of Things ("IoT"), security products – including credentials – are increasingly linked electronically, integrated into software and popular consumer technology platforms and controlled with mobile applications, creating additional functionality and complexity. Seamless access capitalizes on the ability for multiple products and brands to work in tandem, allowing people and assets to move efficiently and safely by adapting access rights for various settings or use cases. These solutions can also provide insights on usage and traffic patterns to boost efficiency, improve hygiene of high-traffic areas and improve visitor, staff and tenant experiences.
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 extensive and versatile product and service portfolio, combined with our deep expertise, which enables 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 enables 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, contractors, homebuilders and engineers;
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 products and solutions as end-users adopt newer technologies in their facilities and homes;
Heightened awareness of security and privacy requirements;
Increased focus on touchless solutions that help promote a healthy environment; and
The shift to a digital, interconnected and increasingly interoperable environment.
We operate in and report financial results for two segments: Allegion Americas and Allegion International, the latter of which provides security products, services and solutions primarily throughout Europe, Asia and Oceania. We sell our products and solutions under the following brands:

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;
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 ("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 in 1974. 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 (AI), video monitoring, machine learning and cybersecurity. For example, in 2023, Allegion Ventures made a $20 million investment in Ambient.ai, an AI powered computer vision intelligence company.

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, new attention on touchless solutions that help promote a healthy environment 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 IoT and AI, 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. As we move into more technologically advanced product categories, we may also compete against new, more specialized competitors and technology companies.
Our success depends on a variety of factors, including brand and reputation, 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. Although price often serves as an important customer decision point, we also compete based on the breadth, innovation and quality of our products and solutions, our ability to custom-configure solutions to meet individual end-user requirements and our global supply chain.

We also offer ongoing aftermarket services, design and installation offerings and locksmith services in select locations.
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 our Access Technologies business, Interflex and our Global Portable Security brands, we also provide products and services directly to end-users.
Our 10 largest customers represented approximately 25% of our total Net revenues in 2023. No single customer represented 10% or more of our total Net revenues in 2023.

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), Builders Hardware Manufacturers Association (BHMA), Connectivity Standards Alliance (CSA), 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 31 principal production and assembly facilities – 18 in our Allegion Americas segment and 13 in our Allegion International segment. We own 16 of these facilities and lease the others. 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, 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.
In late 2022, supply chain disruptions experienced in prior years moderated and the availability of many raw material categories improved. The prior actions taken to create supply flexibility and improved safety stocks permitted reliable supply during the year. See "Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations" for a more detailed discussion of these trends and challenges.
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 try to ensure the protection and enforcement of our intellectual property rights. We use trademarks on nearly all of 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
We are committed to investing in our research and development capabilities with a focus on innovations that will deliver growth through the introduction of new products and solutions. In addition, we invest in initiatives that continuously drive improvements in product cost, quality, safety and sustainability.
Our research and development team is managed as a global, collaborative group to identify and develop new technologies and worldwide product platforms. Our regionally located resources leverage expertise in local standards and configurations and apply those to adapt products for the benefit of our customers. Further, we operate a global technology center in Bengaluru, India, which augments and supports our regional engineering and technology 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 of December 31, 2023, we had approximately 12,400 employees worldwide, of which approximately 12,200 are full-time employees. Approximately 48% of employees are employed within the U.S. and approximately 52% based outside the U.S. Among our U.S. based employees, approximately 15% 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. Our employee base is supplemented by contingent labor where business demand fluctuates or we experience short-term needs for specialized skills. 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.
12

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 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 on-going 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 reskilling and upskilling existing employees, as well as strengths-based leadership curriculum and global programs for employee mentoring and coaching.
Engagement and Diversity, Equity and Inclusion ("DEI")
Engagement and DEI 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 diverse members of their teams.
We believe in fundamental standards that support our employees, while building and maintaining diverse and inclusive workplaces, safe and healthy practices. Employee led resource and affinity groups provide opportunities for women's leadership, early career professionals, allies and members of the LGBTQIA+, Black, veteran and Hispanic communities.
The efforts of Allegion’s DEI Steering Committee, our ELT and our employee resource groups, are driving expectations and accountability while creating role models and change champions. Our DEI strategy has three core pillars:
Learn & listen deeply: Learn to recognize biases and mitigate them. Seek to first understand an individual's perspective rather than respond or act;
Unite widely: Create a workplace where all employees feel welcomed, respected and valued, enabling customers to more easily connect with our brands through our people; and
Take action: Identify the unique things that impact our organization, our communities and our industry.
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. We continue to adapt to changing health conditions at a local level and support a wide range of health and safety measures, including encouraging preventative health measures such as COVID-19 and influenza vaccines and booster shots.
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 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 our business in a safe, environmentally responsible and sustainable manner, in compliance with all applicable EHS laws and regulations, and in a manner that helps promote and protect the health and safety of our environment, associates, customers, contractors and members of our local communities worldwide. We operate with principles that support our proactive commitments, including:
Integrating sound EHS and sustainability strategies in all elements of our business functions, including objectives and measurements;
Conducting periodic, formal evaluation of our compliance status and annual review of objectives and targets;
Creating a workplace culture where all employees are responsible for safety;
Making continuous improvements in EHS and sustainability management systems and performance, including the reduction in the usage of natural resources, waste minimization, prevention of pollution and prevention 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 the recycling and reuse of materials, where feasible; and
Acting in a way that shows sensitivity to community concerns about EHS and sustainability issues.
We recognize that these principles are critical to our future success. We have a dedicated environmental program designed to reduce the utilization and generation of hazardous materials during the manufacturing process and to remediate any identified environmental concerns. As to the latter, 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 21 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 committed to 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, and includes our materiality matrix of ESG priorities.

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 operations and performance have been, and are expected to continue to be, impacted by global macroeconomic factors. Ongoing macroeconomic challenges could adversely impact our business, results of operations, financial conditions and cash flows.
Macroeconomic challenges, including ongoing supply chain disruptions and delays, material, electronic component and labor shortages, cost inflation, rising interest rates and volatility in the capital markets, have impacted, and may continue to impact, our business, our customers and our suppliers. These challenges may also 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, could have a material adverse impact on our business, results of operations, financial condition and cash flows.
Further, demand for our products and solutions is impacted by the strength of institutional, commercial and residential construction and remodeling markets, which are sensitive to national, regional and local economic conditions. As a result, deterioration of these macroeconomic conditions (or weakness in these conditions existing for an extended period of time), a decline in general economic activity or recession in the U.S. or global economy could slow demand for new construction or remodeling projects and result in our customers cancelling or delaying orders, which in turn could erode average selling prices and result in declines in our revenues, profitability and cash flows.
Increased prices and inflation could negatively impact our margin performance and our financial results.
Elevated levels of inflation, including rising prices for raw materials, parts and components, freight, packaging, labor and energy, increases 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.
Additionally, we are exposed to fluctuations in other costs such as packaging, freight, labor and energy prices. If inflation in these costs increases 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 economic risks.
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, sanctions, import and export regulations, including imposition of burdensome tariffs and quotas, and customs duties;
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;
15

Table of Contents
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.
Our business relies on the institutional, commercial and residential construction and remodeling markets.
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 overall 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. Weakness or instability in one or more of these markets may cause current and potential customers to delay or cancel major capital projects or otherwise choose not to make purchases, which could negatively impact the demand for our products and solutions and erode average selling prices.
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 2023 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, 2023, the net carrying value of our goodwill and other indefinite-lived intangible assets totaled approximately $1.4 billion and $104 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. Based on our 2023 assessment, it was determined that two of the Company's indefinite-lived trade names in the International segment were impaired, and we recorded a $7.5 million impairment charge.
The capital and credit markets are important to our business.
Continued 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.
16

Table of Contents
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 billion of outstanding indebtedness at December 31, 2023. In addition, we have a senior unsecured revolving credit facility (the "2021 Revolving Facility") that permits borrowings of up to $500 million. 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, 2023, our borrowings included a variable rate term loan facility (the "2021 Term Facility", and together with the 2021 Revolving Facility, the "2021 Credit Facilities"). The 2021 Credit Facilities had a combined outstanding variable rate balance of $225.0 million at December 31, 2023, which exposes us to variable interest rate risk. Applicable variable interest rates have increased throughout 2023, resulting in increased Interest expense. 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 2021 Revolving Facility. If variable base rates under the 2021 Credit Facilities continue to increase in the future, our Interest expense could increase as well. For more details about our interest rate exposure under the 2021 Credit Facilities, please see Part II. Item 7A.
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
17

Table of Contents
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.
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.

18

Table of Contents
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 2021 Revolving Facility or pursue other external financing, which may not be readily available. Additionally, our pursuit of new business opportunities that diverge from our core business may expose us to different risks and uncertainties other than those described in this “Risk Factors” section or elsewhere in this Annual Report on Form 10-K. 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 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, such as the COVID-19 pandemic or any other actual or threatened epidemic, pandemic, 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 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.
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.
Disruptions or breaches of our information systems could adversely affect us.
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
20

Table of Contents
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 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.
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 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.
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, regulatory issues or quality control problems in their operations, freight delays and other supply chain constraints and 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, DEI, 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, including a commitment to achieve carbon neutral emissions by 2050. 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
22

Table of Contents
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.
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
23

Table of Contents
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 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 recently 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 approximately 25 countries have implemented the GMT rules. Further, on December 15, 2022, the European Union adopted a Council Directive which requires GMT rules to be transposed into member states’ national laws starting in 2024.
On December 18, 2023, Ireland, the location of our incorporation, enacted legislation which includes provisions regarding the implementation of GMT. We are currently assessing the impact of the legislation, but we expect our effective income tax rate to increase beginning in 2024. Further, we anticipate the continued and ongoing release of OECD GMT interpretive guidance. 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 33% of our issued ordinary shares and further authorized our Board of Directors to issue up to 5% 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.
24

Table of Contents
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 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 contains 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. Further, we have an employee security awareness program in place and a security training program for technical personnel that provides mandatory and on-demand training.
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, and third party audits on portions of our cybersecurity program or processes apply the NIST Cybersecurity Framework 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. These risks are further described in the risk factors within Item 1A, particularly under the headings “We may be subject to risks relating 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 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 its quarterly board meeting, 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;
26

Table of Contents
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).
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. 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 sales offices, engineering centers, 31 principal production and assembly facilities and several distribution centers throughout the world. Our active properties represent about 7.6 million square feet, of which approximately 48% is leased.
We own 16 of our production and assembly facilities, with the remainder under long-term lease arrangements. We believe that our plants have been well maintained, are generally in good condition and are 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 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 14, 2024, the number of record holders of ordinary shares was 1,920.

Dividend Policy
Our Board of Directors declared dividends of $0.45 per ordinary share on February 9, 2023, April 13, 2023, September 7, 2023 and December 7, 2023. On February 7, 2024, our Board of Directors declared a dividend of $0.48 per ordinary share payable on March 29, 2024, to shareholders of record on March 15, 2024. We paid a total of $158.7 million in cash for dividends to ordinary shareholders during the year ended December 31, 2023. 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, 2023, we had distributable reserves of $3.9 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.

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
Industry Trends and Outlook
During 2023, we experienced stable demand for our non-residential products and services in our Allegion Americas segment. As the year progressed, customers began adjusting ordering patterns in response to our reduced lead times due to improved supply chain and operational execution, which resulted in abnormal seasonality of non-residential revenues in 2023. Macroeconomic conditions had a more challenging impact on the demand for our residential products in our Allegion Americas segment which negatively impacted revenues. We also experienced a continued softening of demand in our Global Portable Security and China businesses in our Allegion International segment.
Growth in electronic security products and solutions remained strong throughout 2023 and continues to outperform mechanical products. We expect growth in the global electronic security product and solution categories we serve to continue to outperform growth in mechanical products and solutions over the long-term, as end-users adopt newer technologies in their facilities and homes.
We expect the security products industry will benefit from favorable long-term demographic trends such as continued urbanization of the global population, increased concerns about safety and security and technology-driven innovation.
The economic 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."
2023 and 2022 Significant Events
Acquisition of plano.group ("plano")
On January 3, 2023, we acquired plano for a closing purchase price of $36.6 million. This acquisition was financed through cash on hand and borrowings under the 2021 Revolving Facility. Plano is a SaaS workforce management solution based in Germany, and has been incorporated into our Allegion International segment.
Acquisition of the Access Technologies business
On July 5, 2022, we completed the acquisition of the Access Technologies business for a purchase price of $915.2 million. This acquisition was financed by the net proceeds from the issuance of our 5.411% Senior Notes, together with borrowings under the 2021 Revolving Facility. The Access Technologies business has been integrated into our Allegion Americas segment.
The Access Technologies business is a leading manufacturer, installer and service provider of automatic entrance solutions in North America, primarily in the U.S. and Canada. Its diversified customer base centers on non-residential settings, including retail, healthcare, education, commercial offices, hospitality and government. This acquisition helps us create a more comprehensive portfolio of access solutions, with the addition of automated entrance solutions. Additionally, the Access Technologies business adds an expansive service and support network throughout the U.S. and Canada, broadening our solutions to national, regional and local customers, and complementing our existing strengths in these non-residential markets.
Divestiture of Milre
In September 2022, we sold Milre Systek Co. Ltd. ("Milre") in South Korea for an immaterial amount. As a result of the sale, we recorded a net loss on divestiture of $7.6 million.

Impairment of Intangible Assets
As discussed in Note 7 to the Consolidated Financial Statements, the results of our 2023 impairment test indicated that the estimated fair value of two indefinite-lived trade names in our International segment were determined to be less than book value. Consequently, intangible asset impairment charges totaling $7.5 million were recorded. The impairments related to declines in volumes which reduced the brands' expected future cash flows.
Financing activities
On June 22, 2022, Allegion US Holding Company Inc., a wholly-owned subsidiary of the Company ("Allegion US Hold Co"), issued $600.0 million aggregate principal amount of its 5.411% Senior Notes due 2032 (the “5.411% Senior Notes”). The 5.411% Senior Notes require semi-annual interest payments on January 1 and July 1, and mature on July 1, 2032. We incurred and deferred $5.9 million of discounts and financing costs associated with the 5.411% Senior Notes, which is being amortized to Interest expense over their 10-year term, as well as $4.3 million of third party financing costs that were recorded within Interest expense on the Consolidated Statement of Comprehensive Income for the year ended December 31, 2022.
Dividends and Share Repurchases
We paid quarterly dividends of $0.45 per ordinary share to shareholders on record as of March 15, 2023, June 15, 2023, September 18, 2023, and December 18, 2023, for a total of $158.7 million and repurchased approximately 0.5 million ordinary shares for approximately $59.9 million during the year ended December 31, 2023.
We paid quarterly dividends of $0.41 per ordinary share to shareholders on record as of March 16, 2022, June 16, 2022, September 16, 2022, and December 16, 2022, for a total of $143.9 million and repurchased approximately 0.5 million ordinary shares for approximately $61.0 million during the year ended December 31, 2022.

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, 2022, compared to the year ended December 31, 2021, see “Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our 2022 Annual Report on Form 10-K filed with the SEC on February 22, 2023.
Net Revenues
Net revenues for the year ended December 31, 2023, increased by 11.6%, or $378.9 million, as compared to the year ended December 31, 2022, due to the following:
Pricing7.5 %
Volume(2.3)%
Acquisitions / divestitures6.2 %
Currency exchange rates0.2 %
Total11.6 %
The increase in Net revenues was driven by improved pricing across our major businesses, our acquisitions of the Access Technologies and plano businesses and favorable foreign currency exchange rate movements. These increases were partially offset by lower volumes and a divestiture in the prior year. Increased pricing was the result of multiple pricing initiatives implemented to help mitigate the impact of inflation. We will continue to monitor the inflationary pressures to our businesses and address them through pricing initiatives where appropriate.
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, 2023, Cost of goods sold as a percentage of Net revenues decreased to 56.7% from 59.6%, as compared to the year ended December 31, 2022, due to the following:
Pricing and productivity in excess of inflation and investment spending(3.8)%
Volume / product mix0.3 %
Acquisitions / divestitures0.5 %
Currency exchange rates0.3 %
Restructuring / integration / acquisition expenses(0.2)%
Total(2.9)%
Cost of goods sold as a percentage of Net revenues decreased primarily due to the pricing and productivity improvements, which exceeded the impacts from inflation and investment spending, and lower restructuring and acquisition costs year-over-

year. These decreases were partially offset by unfavorable product mix, lower gross margins associated with our acquired Access Technologies business and unfavorable foreign currency exchange rate movements.
Pricing and productivity in excess of inflation and investment spending includes the impact to Costs 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, 2023, Selling and administrative expenses as a percentage of Net revenues increased to 23.7% from 22.5%, as compared to the year ended December 31, 2022, due to the following:
Inflation in excess of productivity and investment spending0.7 %
Volume leverage0.5 %
Acquisitions / divestitures(0.3)%
Restructuring / integration / acquisition expenses0.3 %
Total1.2 %
Selling and administrative expenses as a percentage of Net revenues increased due to inflation in excess of productivity and investment spending, as well as unfavorable volume leverage and year-over-year increase in acquisition and integration expenses. These increases were partially offset by the beneficial impact from current and prior year acquisition and divestiture activity.
Inflation in excess of productivity is primarily the result of increases to variable compensation. 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, 2023, increased $122.0 million as compared to the year ended December 31, 2022, and Operating margin increased to 19.4% from 17.9%, due to the following:

Restructuring / integration / acquisition expenses(4.0)(0.1)%
December 31, 2023$708.4 19.4 %
The increase in Operating income was driven by pricing and productivity improvements in excess of inflation and investment spending and the contribution from recent acquisition and divestiture activity. These increases were partially offset by unfavorable volume/product mix, unfavorable foreign currency exchange rate movements, a year-over-year increase in restructuring and acquisition costs and impairment charges on intangible assets recorded in the current year.
The increase in Operating margin was driven by pricing and productivity improvements in excess of inflation and investment spending. The increase was partially offset due to an unfavorable volume/product mix, unfavorable foreign currency exchange rate movements, the year-over-year increase in restructuring, integration and acquisition expenses and the full year dilutive impact to Operating margin from our Access Technologies business as well as the impairment charges recorded in the current year.
Interest Expense
Interest expense for the year ended December 31, 2023, increased $17.2 million as compared to the year ended December 31, 2022 due to the full year impact of interest on our 5.411% Senior Notes issued in June of 2022 as well as an increase in the variable interest rate on borrowings under our 2021 Term Facility.

For the year ended December 31, 2023, Other income, net, decreased $9.7 million compared to 2022, primarily due to an unfavorable net periodic pension and postretirement benefit cost (income), less service cost in 2023 compared to 2022, which was partially offset by an increase in interest income in 2023 compared to 2022.
Provision for Income Taxes
For the year ended December 31, 2023, our effective tax rate was 12.4%, compared to 10.9% for the year ended December 31, 2022. The increase in the effective tax rate was primarily due to the mix of income earned in higher tax rate jurisdictions, which was partially offset by the favorable resolutions of uncertain tax positions.

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 (the "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. Due to a reporting change effective January 1, 2023, results for our Global Portable Security brands (inclusive of the AXA, Kryptonite and Trelock businesses) are now fully reflected within the Allegion International segment. Accordingly, the 2022 summary of operations by reportable segment below have been recast to conform with the current period presentation. The impact of this recast was to realign approximately $20.9 million of Net revenues and $2.1 million of Segment operating income for the year ended December 31, 2022, from the Allegion Americas segment to the Allegion International segment.

Allegion Americas
Our Allegion Americas segment is a leading provider of security products, services and solutions throughout North America. The segment sells a broad range of products and solutions including, locks, locksets, portable locks, key systems, door controls and systems, exit devices, doors, accessories, electronic security products, access control systems and software and service solutions to customers in commercial, institutional and residential facilities, including the education, healthcare, government, hospitality, retail, commercial office and single and multi-family residential markets. This segment’s primary brands are LCN, Schlage, Von Duprin and Stanley Access Technologies, which we utilize with permission in accordance with the terms of the Access Technologies acquisition agreement ("Stanley" is the property of Stanley Logistics L.L.C).
Net revenues
Net revenues for the year ended December 31, 2023, increased by 15.1%, or $382.9 million, as compared to the year ended December 31, 2022, due to the following: 
Pricing8.3 %
Volume(0.9)%
Acquisitions7.9 %
Currency exchange rates(0.2)%
Total15.1 %
The increase in Net revenues was driven by improved pricing and the acquisition of our Access Technologies business. These increases were partially offset by lower volumes and unfavorable foreign currency exchange rate movements. Increased pricing was the result of multiple pricing initiatives implemented to help mitigate the impact of inflation. We will continue to monitor the inflationary pressures to our businesses and address them through pricing initiatives where appropriate.
Net revenues from non-residential products (excluding Net revenues from our acquired Access Technologies business), increased by a low double-digits percent compared to the prior year, driven by improved pricing which was offset by lower volumes. Pricing improvements reflect the realization of initiatives taken by the Company in response to inflation pressures.
Net revenues from residential products decreased by a low single digits percent compared to the prior year. Stable pricing was offset by lower volumes during the year. During 2023, we experienced a softening in market demand for our residential products, due in part to lower consumer sentiment, which resulted in reduced sales volumes. Further, market conditions for new residential construction remained soft throughout 2023 and we anticipate softness in demand for our residential products to continue into 2024.
Growth in 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 twenties percent compared to the prior year, driven by improved pricing and higher volumes. Continued strong demand and improvements around the availability of materials and components helped drive the increase in revenues compared to 2022. We expect continued growth from the sale of electronic products in 2024 given the combination of stable demand and our pricing initiatives.
Operating income/margin
Segment operating income for the year ended December 31, 2023, increased $146.0 million, and Segment operating margin increased to 26.0% from 24.2% as compared to the year ended December 31, 2022, due to the following:

Allegion International
Our Allegion International segment provides security products, services and solutions primarily throughout Europe, Asia and Oceania. The segment offers end-users a broad range of products, services and solutions including locks, locksets, portable locks, key systems, door controls and systems, exit devices, doors, electronic security products, access control systems, time and attendance and workforce productivity solutions, among other software and service solutions. This segment’s primary brands are AXA, Bricard, Briton, CISA, Gainsborough, Interflex, Kryptonite and SimonsVoss.
Net revenues
Net revenues for the year ended December 31, 2023, decreased by 0.5%, or $4.0 million, as compared to the year ended December 31, 2022, due to the following:
Pricing4.9 %
Volume(7.4)%
Acquisitions / divestitures0.7 %
Currency exchange rates1.3 %
Total(0.5)%
The decrease in Net revenues was driven by lower volumes, particularly within our Global Portable Security business. These decreases were partially offset by improved pricing across our major businesses throughout the segment as well as favorable foreign currency exchange rate movements. The impact from the acquisition of plano in 2023 was partially offset by the divestiture of Milre in 2022.
A softening demand throughout much of Europe, Asia and Oceania in 2023 has impacted several of our businesses. While we anticipate pricing initiatives to continue to positively contribute to revenue growth in 2024, volume growth will likely continue to be tempered until prevailing macroeconomic and geopolitical conditions improve.
Operating income margin
Segment operating income for the year ended December 31, 2023, decreased $12.3 million, and Segment operating margin decreased to 7.9% from 9.5% as compared to the year ended December 31, 2022, due to the following:

The decreases in Segment operating income and Segment operating margin were primarily driven by unfavorable volume/product mix, a year-over-year increase in restructuring, integration and acquisition expenses, and impairment charges on intangible assets recorded in the current year. These decreases were partially offset by pricing and productivity improvements in excess of inflation and investment spending, favorable movements in foreign currency exchange rates and both prior year and current year acquisition and divestiture activity.

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 2021 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, dividend payments and principal and interest payments on our long-term debt. Long-term financing needs depend largely on

Table of Contents
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, 2023, approximately 89% 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 2021 Revolving Facility, as of December 31, 2023, 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 12 months. Further, we do not anticipate any covenant compliance challenges with any of our outstanding indebtedness for at least the next 12 months. We also believe existing availability under the 2021 Credit Facilities 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.

Operating activities: Net cash provided by operating activities for the year ended December 31, 2023, increased by $141.1 million compared to 2022, driven primarily by higher net earnings and higher cash provided by working capital.
Investing activities: Net cash used in investing activities for the year ended December 31, 2023, decreased by $865.0 million compared to 2022, primarily due to the Access Technologies acquisition in 2022, which was partially offset by an increase of $20.2 million in capital expenditures compared to 2022 and an increase in other investments by $6.2 million compared to 2022.
Financing activities: Net cash used in financing activities for the year ended December 31, 2023, changed by $735.7 million compared to 2022. In 2022, we issued $600.0 million of Senior Notes and had net borrowings of $69.0 million on the 2021 Revolving Facility to finance the acquisition of the Access Technologies business. In 2023, we repaid the remaining borrowings on the 2021 Revolving Facility. The remaining change in cash used in financing activities was primarily due to an increase in dividend payments partially offset by slightly less cash used to repurchase shares in 2023 compared to 2022.

As of December 31, 2023, we have an unsecured Credit Agreement in place, consisting of the $250.0 million 2021 Term Facility, and the 2021 Revolving Facility (together with the 2021 Term Facility, the “2021 Credit Facilities”). The 2021 Credit Facilities mature on November 18, 2026. The 2021 Term Facility amortizes in quarterly installments at the following rates: 1.25% per quarter from March 31, 2022 through March 31, 2025, 2.5% per quarter starting June 30, 2025 through September 30, 2026, with the remaining balance due on November 18, 2026. Principal amounts repaid on the Term Facility may not be reborrowed.
The 2021 Revolving Facility provides aggregate commitments of up to $500.0 million, which includes up to $100.0 million for the issuance of letters of credit. In July 2022, we borrowed $340.0 million under the 2021 Revolving Facility to partially fund our acquisition of the Access Technologies business. We subsequently repaid $271.0 million, resulting in $69.0 million of borrowings outstanding on the 2021 Revolving Facility as of December 31, 2022. In 2023, we repaid the remaining balance, resulting in no outstanding balance on the 2021 Revolving Facility as of December 31, 2023. We also had $18.4 million of letters of credit outstanding as of December 31, 2023. Outstanding borrowings under the 2021 Revolving Facility may be repaid at any time without premium or penalty, and amounts repaid may be reborrowed.
Outstanding borrowings under the 2021 Credit Facilities accrue interest at our option of (i) a Bloomberg Short-Term Bank Yield Index (“BSBY”) rate 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, 2023, outstanding borrowings under the 2021 Credit Facilities accrued interest at BSBY plus a margin of 1.125%, resulting in an interest rate of 6.581%. 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 Credit Agreement requires us to comply with a maximum leverage ratio as defined within the agreement. As of December 31, 2023, our leverage ratio of approximately 2.0 was significantly below the covenant requirement, and we do not anticipate any potential concerns for at least the next 12 months.
As of December 31, 2023, we also have $400.0 million outstanding of 3.200% Senior Notes due 2024 (the “3.200% Senior Notes”), $400.0 million outstanding of 3.550% Senior Notes due 2027 (the “3.550% Senior Notes”), $400.0 million outstanding of 3.500% Senior Notes due 2029 (the “3.500% Senior Notes”), and $600.0 million outstanding of 5.411% Senior Notes due 2032 (the “5.411% Senior Notes” and all four senior notes collectively, the "Senior Notes"). The 3.200% Senior Notes, 3.550% Senior Notes, 3.500% Senior Notes, and 5.411% Senior Notes all require semi-annual interest payments, and will mature on October 1, 2024, October 1, 2027, October 1, 2029, and July 1, 2032, respectively. We expect the availability on the 2021 Revolving Facility, along with cash on hand, will provide sufficient liquidity to repay the 3.200% Senior Notes due in the fourth quarter of 2024, if needed.
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, 2023, 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 9 to the Consolidated Financial Statements. Expected principal and interest payments related to our long-term indebtedness in 2024 amount to $412.6 million and $97.1 million, respectively, given our current level of indebtedness and effective interest rates as of December 31, 2023.

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:
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 12 months.
Leases – We have numerous real estate and equipment leasing arrangements for which we are a lessee. See Note 11 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 2024 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 better 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, 2023, we had net pension liabilities of $0.3 million, which consist of plan assets of $512.1 million and benefit obligations of $512.4 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, 2023, the funded status of our U.S. pension plans increased to 101.6% from 97.8% at December 31, 2022. The funded status for our non-U.S. pension plans increased to 98.5% at December 31, 2023 from 97.4% at December 31, 2022. The funded status for all of our pension plans at December 31, 2023 increased to 99.9% from 97.6% at December 31, 2022. We currently expect to contribute approximately $5 million to our plans worldwide in 2024.
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 2023, while a 0.5% rate decline in the estimated return on assets would have increased net periodic pension benefit cost by approximately $2.4 million. For further details on defined benefit plan activity, see Note 12 to the Consolidated Financial Statements.
Income Taxes – At December 31, 2023, we have total unrecognized tax benefits for uncertain tax positions of $45.1 million and $9.0 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 18 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 21 to the Consolidated Financial Statements for additional information.
Guarantor Financial Information
Allegion US Hold Co is the issuer of the 3.200% Senior Notes, 3.550% Senior Notes and 5.411% 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 3.200% Senior Notes, 3.550% Senior Notes and 5.411% 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 3.200% Senior Notes, 3.550% Senior Notes and 5.411% 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 3.200% Senior Notes, 3.550% Senior Notes and 5.411% 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
39

Table of Contents
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 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 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 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 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, and June 22, 2022.
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.



40

Table of Contents
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 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 are the 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
41

Table of Contents
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 contingencies; 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.

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 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, 2023, 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 $2.9 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, 2023.
Interest Rate Exposure
Of our total outstanding indebtedness of $2.0 billion as of December 31, 2023, approximately 89% incurs fixed-rate interest and is therefore not exposed to the risk of rising variable interest rates. However, outstanding borrowings under the 2021 Credit Facilities accrue variable rate interest at our option of (i) a BSBY rate 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, 2023, the outstanding borrowings of $225.0 million under the 2021 Credit Facilities accrue interest at BSBY plus a margin of 1.125%, resulting in an interest rate of 6.581%. Applicable variable interest rates increased throughout 2023, resulting in increased Interest expense. 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 $18.4 million of letters of credit outstanding and unused availability of $481.6 million under the 2021 Revolving Facility as of December 31, 2023. A hypothetical increase of 1% in the interest rate on the variable rate borrowings under our 2021 Credit Facilities would increase our interest expense over the next twelve months by $2.2 million based on the balances outstanding for these borrowings as of December 31, 2023. If the BSBY or other applicable base rates of the 2021 Credit Facilities 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 Securities Exchange Act of 1934, as amended (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, 2023, 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, 2023. 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, 2023.
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, 2023 and 2022, 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, 2023, 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, 2023, 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, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2023 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, 2023, 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.
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.

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

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 20 to the consolidated financial statements, the Company has two principal revenue streams, tangible product sales and services. For the year ended December 31, 2023, the Company’s net revenues were $3,650.8 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). Service offerings include inspection, maintenance and repair, aftermarket, design and installation and locksmith services, as well as software as a service solutions. Unlike the single performance obligation to ship a product or bundle of products, revenue recognition related to services is delayed until 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.
