Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of Allegion Public Limited Company

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, 2021 and 2020, 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, 2021, 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, 2021, 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, 2021 and 2020**,** and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021 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, 2021, 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.

Goodwill Impairment Assessment - Allegion International Reporting Unit

As described in Notes 2 and 5 to the consolidated financial statements, the Company’s consolidated goodwill balance was $803.8 million as of December 31, 2021, and the goodwill associated with the Allegion International reporting unit was $302.6 million. As disclosed by management, goodwill is tested annually for impairment during the fourth quarter or whenever there is a significant change in events or circumstances that indicate that the fair value of the reporting unit is more likely than not less than the carrying amount of the reporting unit. If the estimated fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is not impaired. To the extent that the carrying value of the reporting unit exceeds its estimated fair value, a goodwill impairment charge will be recognized for the amount by which the carrying value of the reporting unit exceeds its fair value, not to exceed the carrying amount of goodwill. For the annual impairment analysis, the estimated fair value of the Allegion International reporting unit was 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 management’s estimates of revenue growth rates, margin assumptions, and discount rates. The market approach requires the determination of an appropriate peer group, which is utilized to derive estimated fair values based on selected market multiples.

The principal considerations for our determination that performing procedures relating to the goodwill impairment assessment of the Allegion International reporting unit is a critical audit matter are (i) the significant judgment by management when developing the fair value of the reporting unit; (ii) a high degree of auditor judgment, subjectivity, and effort in performing procedures and evaluating management’s significant assumptions related to revenue growth rates, discount rates, peer group determination, and selected market multiples; and (iii) the audit effort involved the use of professionals with specialized skill and knowledge.

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 management’s goodwill impairment assessment, including controls over the valuation of the Allegion International reporting unit. These procedures also included, among others (i) testing management’s process for developing the fair value estimate of the Allegion International reporting unit; (ii) evaluating the appropriateness of the income and market approaches; (iii) testing the completeness and accuracy of underlying data used in the approaches; and (iv) evaluating the reasonableness of the significant assumptions used by management related to revenue growth rates and discount rates in the income approach, and the peer group determination and selected market multiples in the market approach. Evaluating management’s assumptions related to revenue growth rates involved evaluating whether the assumptions used by management were reasonable considering (i) the current and past performance of the reporting unit, (ii) the consistency with external market and industry data, and (iii) whether the assumption was consistent with evidence obtained in other areas of the audit. Evaluating the Company’s peer group determination included assessing the appropriateness of the identified peer companies. Professionals with specialized skill and knowledge were used to assist in the evaluation of management’s income and market approaches, and the discount rates, peer group determination, and selected market multiples assumptions.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 – DESCRIPTION OF COMPANY AND BASIS OF PRESENTATION

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

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

NOTE 2 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

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

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

Equity method affiliates represent unconsolidated entities over which the Company demonstrates significant influence but does not have a controlling financial interest. The Company is also required to consolidate variable interest entities in which it bears a majority of the risk to the entity’s potential losses or stands to gain from a majority of the entity’s expected returns.

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

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

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

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

Allowance for Doubtful Accounts: The Company provides for an allowance for doubtful accounts and notes receivable, which represents the best estimate of expected lifetime credit losses inherent in the Company’s accounts and notes receivable portfolios. The Company's estimates are influenced by a continuing credit evaluation of customers' financial condition, trade accounts and notes receivable aging and historical loss experience, as well as reasonable and supportable forecasts of future economic conditions. The Company has reserved $5.4 million and $6.2 million for doubtful accounts and notes receivable as of December 31, 2021 and 2020, respectively.

F-7

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

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

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

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

Investments: The Company periodically invests in debt or equity securities of start-up companies and/or development stage technology or other companies without acquiring a controlling interest. The Company applies the equity method of accounting when the Company has the ability to exercise significant influence over the operating and financial decision making of the investee. Investments in equity method affiliates totaled $11.0 million and $17.4 million as of December 31, 2021 and 2020, respectively. Equity investments that have readily determinable fair values in which the Company does not have significant influence are measured at fair value, with any unrealized holding gains and losses being recorded to earnings. Investments without readily determinable fair values are measured at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or similar investment of the same issuer and are qualitatively assessed for impairment indicators each reporting period. Investments in debt and equity securities not accounted for under the equity method of accounting totaled $35.8 million and $13.7 million as of December 31, 2021 and 2020, respectively. The Company's investments are recorded within Other noncurrent assets within the Consolidated Balance Sheets.

Leases: The Company records a right-of-use ("ROU") asset and lease liability for substantially all leases for which it is a lessee. At inception of a contract, the Company considers all relevant facts and circumstances to assess whether or not the contract represents a lease by determining whether or not the contract conveys the right to control the use of an identified asset, either explicit or implicit, for a period of time in exchange for consideration. Judgment and estimation is also required in determining the lease classification and the amount of the ROU asset and corresponding lease liability for each lease, which includes determining the appropriate lease term and an applicable discount rate. The Company assesses the specific terms and conditions of each lease to determine the appropriate classification as either an operating or finance lease. Substantially all of the Company's leases for which the Company is a lessee are classified as operating leases. In determining the appropriate length of the lease term, both the minimum period over which lease payments are required plus any renewal options that are both within the Company's control to exercise and reasonably certain of being exercised as of lease commencement are considered. If at lease commencement date, a lease has a term of less than 12 months and does not include a purchase option that is reasonably certain to be exercised, the Company does not include the lease as part of its ROU asset or lease liability. If the Company enters into a large number of leases in the same month with the same terms and conditions, these are considered a group (portfolio). There are no material residual value guarantees provided by the Company nor any restrictions or covenants imposed by any leases to which the Company is a party.

As a lessee, the Company categorizes its leases into two general categories: real estate leases and equipment leases. The Company's real estate leases include leased production and assembly facilities, warehouses and distribution centers and office space. The Company's equipment leases include vehicles, material handling equipment, other machinery and equipment utilized in the Company's production and assembly facilities, warehouses and distribution centers, laptops and other IT equipment and other miscellaneous leased equipment.

The terms and conditions of real estate leases can vary significantly from lease to lease. The Company assesses the specific terms and conditions of each real estate lease to determine the amount of the lease payments and the length of the lease term, which includes the minimum period over which lease payments are required plus any renewal options that are both within the Company's control to exercise and reasonably certain of being exercised upon lease commencement. The Company assesses all relevant factors to determine if sufficient incentives exist as of lease commencement to conclude whether or not renewal is

F-8

reasonably certain. When available, the Company will utilize the rate implicit in the lease as the discount rate to determine the lease liability. However, as this rate is not available for most leases, the Company will use its incremental borrowing rate for debt instruments with terms approximating the weighted-average term of its real estate or equipment leases to discount the future lease payments over the lease term to present value. The Company does incur variable lease payments for certain of its real estate leases, such as reimbursements of property taxes, maintenance and other operational costs to the lessor. In general, these variable lease payments are not captured as part of the lease liability or ROU asset, but rather are expensed as incurred. Most of the Company's equipment leases are for terms ranging from two to five years, although terms and conditions can vary from lease to lease. The Company applies similar estimates and judgments to its equipment lease portfolio in determining the lease payments, lease term and incremental borrowing rate as it does to its real estate lease portfolio. The Company does not typically incur variable lease payments related to its equipment leases.

Goodwill: The Company records as goodwill the excess of the purchase price of an acquired business over the fair value of the net assets acquired. Once the final valuation has been performed for each acquisition, adjustments may be recorded. Goodwill is tested and reviewed annually for impairment during the fourth quarter or whenever there is a significant change in events or circumstances that indicate the fair value of a reporting unit is more likely than not less than its carrying amount.

Recoverability of goodwill is measured at the reporting unit level. The carrying amount of a reporting unit is compared to its estimated fair value. If the estimated fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is not impaired. To the extent that the carrying value of the reporting unit exceeds its estimated fair value, a goodwill impairment charge will be recognized for the amount by which the carrying value of the reporting unit exceeds its fair value, not to exceed the carrying amount of the reporting unit's goodwill. Estimated fair value of the Company's reporting units is based on two valuation techniques, a discounted cash flow model (income approach) and a market multiple of earnings (market approach), with each method being weighted in the calculation.

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

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

Customer relationships			20			years
Trade names (finite-lived)			25			years
Completed technologies/patents			10			years
Other			7			years

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

Business Combinations: The fair value of consideration paid in a business combination is allocated to the tangible and identifiable intangible assets acquired, liabilities assumed and goodwill. Acquired intangible assets primarily include indefinite-lived trade names, customer relationships and completed technologies. The accounting for business combinations involves a considerable amount of judgment and estimation, including the fair value of acquired intangible assets involving projections of future revenues and cash flows that are either discounted at an estimated discount rate or measured at an estimated royalty rate; fair value of other acquired assets and assumed liabilities, including potential contingencies; and the useful lives of the acquired assets. As a result, in the case of significant acquisitions, the Company normally obtains the assistance of a third-party valuation specialist in estimating fair values of acquired tangible and intangible assets and assumed liabilities. An income approach or market approach (or both) is utilized in accordance with accepted valuation models for significant acquired assets to determine fair value.

Income Taxes: The calculation of the Company’s income taxes involves considerable judgment and the use of both estimates and allocations. Deferred tax assets and liabilities are determined based on temporary differences between financial reporting and tax bases of assets and liabilities, applying enacted tax rates expected to be in effect for the year in which the differences are expected to reverse. The Company recognizes future tax benefits, such as net operating losses and tax credits, to the extent

F-9

that realizing these benefits is considered in its judgment to be more likely than not. The Company regularly reviews the recoverability of its deferred tax assets considering its historic profitability, projected future taxable income, timing of the reversals of existing temporary differences and the feasibility of its tax planning strategies. Where appropriate, the Company records a valuation allowance with respect to future tax benefits.

Cash paid for income taxes, net of refunds, for the twelve months ended December 31, 2021, 2020 and 2019 was $89.1 million, $82.6 million and $103.0 million, respectively.

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

Revenue Recognition: Net revenues are recognized based on the satisfaction of performance obligations under the terms of a contract. A performance obligation is a promise in a contract to transfer control of a distinct product or to provide a service, or a bundle of products or services, to a customer. The Company has two principal revenue streams, tangible product sales and services. Approximately 99% of consolidated Net revenues involve contracts with a single performance obligation, the transfer of control of a product or bundle of products to a customer. Transfer of control typically occurs when goods are shipped from the Company's facilities or at other predetermined control transfer points (for instance, destination terms). The Company's remaining Net revenues involve services, including installation and consulting. 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. In some instances, customer acceptance provisions are included in sales arrangements to give the buyer the ability to ensure the service meets any established criteria. In these instances, revenue recognition is deferred until the performance obligations are satisfied, which could include acceptance terms specified in the arrangement being fulfilled through customer acceptance or a demonstration that established criteria have been satisfied.

Net revenues are measured as the amount of consideration expected to be received in exchange for transferring control of the products or providing the services and takes into account variable consideration, such as sales incentive programs including discounts and volume rebates. The existence of these programs does not preclude revenue recognition but does require the Company's best estimate of the variable consideration to be made based on expected activity, as these items are reserved for as a deduction to Net revenues based on the Company's historical rates of providing these incentives and annual forecasted sales volumes. Sales returns and customer disputes involving a question of quantity or price are accounted for as variable consideration, and therefore, as a reduction to Net revenues and as a contra receivable. At December 31, 2021 and 2020, the Company had a customer claim accrual (contra receivable) of $47.7 million and $48.6 million, respectively. All other incentives or incentive programs where the customer is required to reach a certain level of purchases, remain a customer for a certain period, provide a rebate form or is subject to additional requirements are also considered variable consideration and are accounted for as a reduction of revenue and a liability. At December 31, 2021 and 2020, the Company had a sales incentive accrual of $38.0 million and $35.0 million, respectively. Each of these accruals represents the Company’s best estimate of the most likely amount expected to be received from customers based on historical experience. These estimates are reviewed regularly for accuracy, and if updated information or actual amounts are different from previous estimates, the revisions are included in the Company’s results for the period in which they become known.

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

Environmental Costs: The Company is subject to laws and regulations relating to protecting the environment and is dedicated to an environmental program to reduce the utilization and generation of hazardous materials during the manufacturing process and to remediate identified environmental concerns. The Company is currently engaged in site investigations and remediation activities to address environmental cleanup from past operations at current and former production facilities. The Company regularly evaluates its remediation programs and considers alternative remediation methods that are in addition to, or in

F-10

replacement of, those currently utilized by the Company based upon enhanced technology and regulatory changes. Changes to the Company's remediation programs may result in increased expenses and increased environmental reserves.

The Company is sometimes a party to environmental lawsuits and claims and has, from time to time, received notices of potential violations of environmental laws and regulations from the U.S. Environmental Protection Agency and similar state authorities. It has also been identified as a potentially responsible party ("PRP") for cleanup costs associated with off-site waste disposal at federal Superfund and state remediation sites for past operations. For all such sites, there are other PRPs and, in most instances, the Company’s involvement is minimal. In estimating its liability, the Company has assumed it will not bear the entire cost of remediation of any site to the exclusion of other PRPs who may be jointly and severally liable. The ability of other PRPs to participate has been taken into account, based on the Company's understanding of the parties’ financial condition and probable contributions on a per site basis. Additional lawsuits and claims involving environmental matters are likely to arise from time to time in the future.

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

Research and Development Costs: The Company conducts research and development activities for the purpose of developing and improving new products and services. These costs are expensed when incurred. For the years ended December 31, 2021, 2020 and 2019, expenses related to research and development activities amounted to approximately $73.3 million, $54.4 million and $54.7 million, respectively, and primarily consisted of salaries, wages, benefits, facility costs and other overhead expenses.

Defined Benefit Plans: The Company provides a range of defined benefits, including pension, postretirement and postemployment benefits to eligible current and former employees. Determining the costs associated with such benefits is dependent on various actuarial assumptions, including discount rates, expected returns on plan assets, compensation increases, employee mortality and turnover rates. Actuaries perform the required calculations to determine expense in accordance with GAAP. Actual results may differ from the actuarial estimates and are generally recorded to Accumulated other comprehensive loss and amortized into Net earnings over future periods. The Company reviews its actuarial assumptions at each measurement date and makes modifications to the assumptions as appropriate. Refer to Note 12 for further details on defined benefit plans.

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

Loss Contingencies: Liabilities are recorded for various contingencies arising in the normal course of business, including litigation and administrative proceedings, environmental matters, product liabilities, product warranties, worker’s compensation and other claims. The Company has recorded reserves in the financial statements related to these matters, which are developed using inputs derived from actuarial estimates and historical and anticipated experience data depending on the nature of the reserve and, in certain instances, with consultation of legal counsel, internal and external consultants and engineers. Amounts recorded for identified contingent liabilities are estimates, which are reviewed periodically and adjusted to reflect additional information when it becomes available. Subject to the uncertainties inherent in estimating future costs for these types of liabilities, the Company believes its estimated reserves are reasonable and does not believe the final determination of the liabilities with respect to these matters would have a material effect on the financial condition, results of operations, liquidity or cash flows of the Company for any year.

Financial Instruments: In the normal course of business, the Company uses various financial instruments, including derivative instruments, to manage the risks associated with interest and currency rate exposures. These financial instruments are not used for trading or speculative purposes. When a derivative contract is entered into, the Company designates the derivative instrument as a cash flow hedge of a forecasted transaction, a cash flow hedge of a recognized asset or liability or as an

F-11

undesignated derivative. The Company formally documents its hedge relationships, including identification of the derivative instruments and the hedged items, as well as its risk management objectives and strategies for undertaking the hedge transaction. This process includes linking derivative instruments that are designated as hedges to specific assets, liabilities or forecasted transactions.

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

Recent Accounting Pronouncements

Recently Adopted Accounting Pronouncements:

In December 2019, the FASB issued ASU 2019-12, "Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes." The new guidance was intended to simplify the accounting for income taxes by removing certain exceptions and by updating accounting requirements around franchise taxes, goodwill recognized for tax purposes, the allocation of current and deferred tax expense among legal entities, among other minor changes. This ASU became effective for fiscal years beginning after December 15, 2020, and interim periods within those annual periods. Accordingly, the Company adopted ASU 2019-12 on January 1, 2021, and the adoption did not have a material impact to the Consolidated Financial Statements.

In January 2020, the FASB issued ASU 2020-01, "Investments—Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815): Clarifying the Interactions between Topic 321, Topic 323, and Topic 815." The amendments in ASU 2020-01 clarify the interaction of the accounting for equity securities under Topic 321 and investments accounted for under the equity method of accounting. This ASU became effective for fiscal years beginning after December 15, 2020, and interim periods within those annual periods. Accordingly, the Company adopted ASU 2020-01 on January 1, 2021, and the adoption did not have a material impact to the Consolidated Financial Statements.

Recently Issued Accounting Pronouncements:

In October 2021, the FASB issued ASU No. 2021-08, "Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers." This ASU requires contract assets and contract liabilities (e.g. deferred revenue) acquired in a business combination to be recognized and measured by the acquirer on the acquisition date in accordance with ASC 606, "Revenue from Contracts with Customers". Generally, this new guidance will result in the acquirer recognizing contract assets and contract liabilities at the same amounts recorded by the acquiree. Historically, such amounts were recognized by the acquirer at fair value in purchase accounting. The guidance is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Early adoption is permitted, including in interim periods, for any financial statements that have not yet been issued. The Company elected to early adopt ASU 2021-08 on January 1, 2022, and will apply to all business combinations consummated subsequent to this date.

As a result of the global economic disruption and uncertainty due to the COVID-19 pandemic arising during the first quarter of 2020, the Company concluded a triggering event had occurred as of March 31, 2020, and performed interim impairment tests on the goodwill balances, at that time, of its previous EMEA and Asia Pacific reporting units (which were combined to form the new Allegion International segment effective January 1, 2021). The results of the interim impairment testing indicated that the estimated fair value of the former Asia Pacific reporting unit was less than its carrying value. Consequently, a goodwill impairment charge of $88.1 million was recorded, which is included in Impairment of goodwill and intangible assets in the Consolidated Statement of Comprehensive Income for the year ended December 31, 2020.

NOTE 6 – INTANGIBLE ASSETS

The following table sets forth the gross amount and related accumulated amortization of the Company’s intangible assets at December 31:

						2021																		2020
In millions						Gross carrying amount						Accumulated amortization						Net carrying amount						Gross carrying amount						Accumulated amortization						Net carrying amount
Completed technologies/patents						$	57.9					$	(28.8)					$	29.1					$	59.9					$	(25.1)					$	34.8

Total						$	697.5											$	447.5					$	710.9											$	487.1

Intangible asset amortization expense for the years ended December 31, 2021, 2020 and 2019, was $34.0 million, $31.5 million and $31.2 million, respectively. Future estimated amortization expense on existing intangible assets in each of the next five years amounts to approximately $29.0 million for 2022, $28.8 million for 2023, $28.8 million for 2024, $27.9 million for 2025 and $25.7 million for 2026.

No intangible asset impairment charges were recorded for the year ended December 31, 2021. However, as a result of the global economic disruption and uncertainty due to the COVID-19 pandemic arising during the first quarter of 2020, the Company concluded a triggering event had occurred as of March 31, 2020, and performed interim impairment testing on certain indefinite-lived trade names. Based on these tests, it was determined that three of the Company's indefinite-lived trade names were impaired, and impairment charges of $8.2 million were recorded. Additional intangible asset impairment charges of $5.4 million were recorded in 2020, relating to supply chain disruptions, which reduced a brand's expected future cash flows, and declines in volumes and pricing pressure for a separate subsidiary. During the 2019 annual impairment testing, it was determined that two of the Company's indefinite-lived trade names were impaired, resulting in impairment charges totaling $5.9 million. Intangible asset impairment charges are included in Impairment of goodwill and intangible assets in the Consolidated Statements of Comprehensive Income.

NOTE 7 - ACQUISITIONS

In July 2021, the Company acquired, through its subsidiaries, certain assets of Astrum Benelux B.V. ("Astum Benelux") and 100% of the equity of WorkforceIT B.V. in the Netherlands ("WorkforeceIT"), both of which were previously held under common control and offer workforce management technology products and solutions in the Benelux region of Europe. Neither the assets from Astrum Benelux nor the acquisition of WorkforceIT had a material impact on the Consolidated Financial Statements. Both Workforce IT and the assets acquired from Astrum Benelux were accounted for as a business combination and have been integrated into the Allegion International segment.

In December 2020, the Company acquired the remaining interest of Yonomi, Inc. ("Yonomi"), a U.S. based smart home integration platform provider and innovation leader in IoT Cloud platforms, through one of its subsidiaries. Prior to acquisition, the Company held a noncontrolling interest in Yonomi that was considered an equity method investment. This acquisition was accounted for as a business combination and did not have a material impact on the Consolidated Financial Statements. Yonomi has been integrated into the Allegion Americas segment.

During the years ended December 31, 2021, 2020 and 2019, the Company incurred $4.4 million, $2.3 million and $2.0 million, respectively, of acquisition and integration related expenses, which are included in Selling and administrative expenses in the Consolidated Statement of Comprehensive Income.

NOTE 8 - DIVESTITURES

As previously disclosed, during the fourth quarter of 2020, the net assets of the Company's Qatar Metal Industries ("QMI") business, met the criteria to be classified as held for sale, and accordingly, were written down to fair value, resulting in a Loss on assets held for sale in 2020 of $37.9 million. On February 28, 2021, the Company completed its divestiture of QMI. The completion of the divestiture did not have a material impact to the Consolidated Financial Statements for the year ended December 31, 2021.

F-14

In 2019, the Company closed its production facility in Turkey and sold certain of the production assets thereof. Total proceeds from the sale were approximately $4.1 million, and the Company recorded a loss on divestiture of $24.2 million ($25.5 million, net of tax), primarily driven by the reclassification of $25.0 million of accumulated foreign currency translation adjustments to earnings upon sale. The Company also sold its interests in its Colombia operations in 2019 for a nominal amount, recording a net loss on divestiture of $5.9 million, of which $1.2 million relates to the reclassification of accumulated foreign currency translation adjustments to earnings upon sale. These losses are included within Loss on divestitures in the Consolidated Statements of Comprehensive Income for the year ended December 31, 2019.

NOTE 9 – DEBT AND CREDIT FACILITIES

Unsecured Credit Facilities

On November 18, 2021, the Company entered into a new unsecured credit agreement (the “2021 Credit Agreement”), which refinanced in full the Company's previously outstanding unsecured Credit Facilities. The 2021 Credit Agreement consists of a $250.0 million term loan facility (the “2021 Term Facility”) and a $500.0 million revolving credit facility (the “2021 Revolving Facility” and, together with the 2021 Term Facility, the “2021 Credit Facilities”). The 2021 Credit Facilities mature on November 18, 2026, and are unconditionally guaranteed jointly and severally on an unsecured basis by the Company and Allegion US Holding Company Inc. ("Allegion US Hold Co"), the Company's wholly-owned subsidiary. All obligations under the previously outstanding Credit Agreement were satisfied, all commitments thereunder were terminated, and all guarantees that had been granted in connection therewith were released.

The full amount of the 2021 Term Facility was drawn at closing, with the initial proceeds of $250.0 million primarily used to repay in full the outstanding borrowings under the previously outstanding Term Facility. The 2021 Term Facility will amortize in quarterly installments at the following rates: 1.25% per quarter starting March 31, 2022 through March 31, 2025, 2.5% per quarter starting June 30, 2025 through September 30, 2026, with the balance due on November 18, 2026. The Company may voluntarily prepay outstanding amounts under the 2021 Term Facility at any time without premium or penalty, subject to customary breakage costs. Amounts borrowed under the 2021 Term Facility that are repaid 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. At December 31, 2021, there were no borrowings outstanding on the 2021 Revolving Facility and the Company had $8.7 million of letters of credit outstanding. Commitments under the 2021 Revolving Facility may be reduced at any time without premium or penalty, and amounts repaid may be reborrowed. The Company pays certain fees with respect to the 2021 Revolving Facility, including an unused commitment fee on the undrawn portion of the 2021 Revolving Facility of between 0.090% and 0.200% per year, depending on the Company's credit rating, as well as certain other fees.

Outstanding borrowings under the 2021 Credit Facilities accrue interest at the option of the Company of (i) a Bloomberg Short-Term Bank Yield Index (“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 the Company's credit ratings. At December 31, 2021, the outstanding borrowings under the 2021 Term Facility accrue interest at BSBY plus a margin of 1.125%, resulting in an interest rate of

Gains and losses associated with the Company's non-designated currency derivatives, which are offset by changes in the fair value of the underlying transactions, are included within Other (income) expense, net in the Consolidated Statements of

F-16

Comprehensive Income. At December 31, 2021, the maximum term of the Company’s currency derivatives, both those that are designated as cash flow hedges and those that are not, was less than one year.

Concentration of Credit Risk

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

NOTE 11 - LEASES

Total rental expense for the years ended December 31, 2021, 2020 and 2019, was $45.4 million, $44.2 million and $43.2 million, respectively, and is classified within Cost of goods sold and Selling and administrative expenses within the Consolidated Statements of Comprehensive Income. Rental expense related to short-term leases, variable lease payments or other leases or lease components not included within the ROU asset or lease liability totaled $8.2 million, $9.1 million and $8.1 million, respectively, for the years ended December 31, 2021, 2020 and 2019. No material lease costs have been capitalized on the Consolidated Balance Sheets as of December 31, 2021 or 2020.

NOTE 12 – PENSIONS AND POSTRETIREMENT BENEFITS OTHER THAN PENSIONS

The Company sponsors several U.S. defined benefit and defined contribution plans covering substantially all U.S. employees. Additionally, the Company has non-U.S. defined benefit and defined contribution plans covering eligible non-U.S. employees. Postretirement benefits, other than pensions, provide healthcare benefits, and in some instances, life insurance benefits for certain eligible employees.

Pension Plans

The noncontributory defined benefit pension plans covering non-collectively bargained U.S. employees provide benefits on an average pay formula, while most plans for collectively bargained U.S. employees provide benefits on a flat dollar benefit formula. The non-U.S. pension plans generally provide benefits based on earnings and years of service. The Company also maintains additional other supplemental plans for officers and other key employees.

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

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

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

• Cash, cash equivalents and short-term investments – Short-term investments are valued at their daily net asset value (NAV) per share or the equivalent based upon the fair value of the underlying investments. NAV per share or the equivalent is used for fair value purposes as a practical expedient and is calculated by the investment manager or sponsor of the fund. These investments primarily consist of short-term investment funds.

• Common collective trusts - Common collective trust ("CCT") funds are not publicly traded and are valued at NAV per share or the equivalent based upon the fair value of the underlying investments. NAV per share or the equivalent is used for fair value purposes as a practical expedient and is calculated by the investment manager or sponsor of the applicable fund. CCT funds consist of a variety of publicly traded securities, including equity mutual funds, U.S. government and agency obligations, corporate and non-U.S. bonds, securitized credit and emerging market debt. There are no unfunded commitments, redemption frequency restrictions or other redemption restrictions related to such investments.

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

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

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

F-22

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

The Company made employer contributions of $6.2 million, $6.3 million and $6.0 million to the U.S. pension plans in 2021, 2020 and 2019, respectively. The Company made required and discretionary contributions to its non-U.S. pension plans of $6.0 million, $5.1 million and $10.6 million in 2021, 2020 and 2019, respectively.

The Company currently projects that approximately $5 million will be contributed to its plans worldwide in 2022. The Company’s policy allows it to fund an amount, which could be in excess of or less than the pension cost expensed, subject to the limitations imposed by current tax regulations. The Company anticipates funding the plans in 2022 in accordance with contributions required by funding regulations or the laws of each jurisdiction.

Most of the Company’s U.S. employees are covered by defined contribution plans. Employer contributions are determined based on criteria specific to the individual plans and amounted to approximately $18.3 million, $17.9 million and $15.6 million in 2021, 2020 and 2019, respectively. The Company’s contributions relating to non-U.S. defined contribution plans and other non-U.S. benefit plans were $8.6 million, $7.0 million and $6.0 million in 2021, 2020 and 2019, respectively.

Deferred Compensation Plan

The Company maintains an Executive Deferred Compensation Plan ("EDCP"), which is an unfunded, nonqualified plan that, prior to 2019, permitted certain employees to defer up to 50% of their annual salary and up to 100% of their annual bonus awards, performance stock plan awards and restricted stock units earned until conclusion of their employment with the Company. As of December 31, 2021 and 2020, the deferred compensation liability balance was $18.2 million and $18.1 million, respectively, which was recorded within Postemployment and other benefit liabilities in the Consolidated Balance Sheets.

Postretirement Benefits Other Than Pensions

The Company sponsors a postretirement ("OPEB") plan that provides for healthcare benefits, and in some instances, life insurance benefits, that cover certain eligible retired employees. The Company funds postretirement benefit obligations principally on a pay-as-you-go basis. Generally, postretirement health benefits are contributory with contributions adjusted annually. Life insurance plans for retirees are primarily noncontributory. Net periodic postretirement benefit income is included within Other (income) expense, net within the Consolidated Statements of Comprehensive Income.

The benefit obligation related to the Company's postretirement plans as of December 31, 2021 and 2020 was $4.4 million and $5.2 million, respectively, and is classified as Accrued compensation and benefits and Postemployment and other benefit liabilities within the Consolidated Balance Sheets. Net periodic postretirement benefit income was not material for any of the years ended December 31, 2021, 2020 or 2019, nor is it projected to be material for 2022. Benefit payments for postretirement benefits, which are net of expected plan participant contributions and Medicare Part D subsidies, are expected to be less than $1 million per year for the foreseeable future.

NOTE 13 – FAIR VALUE MEASUREMENTS

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

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

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

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

F-23

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

Assets and liabilities measured at fair value at December 31, 2021, were as follows:

			Fair value measurements																		Total fair value

Total financial instruments not carried at fair value			$	—					$	1,541.4					$	—					$	1,541.4

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

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

*•*Derivative instruments – These instruments include foreign currency contracts for non-functional currency balance sheet exposures, including both those that are and are not designated as cash flow hedges. The fair value of the foreign currency contracts is determined based on a pricing model that uses spot rates and forward prices from actively quoted currency markets that are readily accessible and observable.

F-24

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

• Debt – These instruments are recorded at cost and include senior notes maturing through 2029. The fair value of the long-term debt instruments is obtained based on observable market prices quoted on public exchanges for similar instruments.

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

The methodologies used by the Company to determine the fair value of its financial assets and liabilities at December 31, 2021, are the same as those used at December 31, 2020.

NOTE 15 – SHARE-BASED COMPENSATION

Under the Company's incentive stock plan, the total number of ordinary shares authorized by the shareholders is 8.0 million, of which 2.6 million remain available as of December 31, 2021 for future incentive awards.

Compensation Expense

Share-based compensation expense is included in Cost of goods sold and Selling and administrative expenses within the Consolidated Statements of Comprehensive Income. The following table summarizes the expenses recognized for the years ended December 31:

Stock Options / RSUs

The average fair value of the stock options granted for the years ended December 31, 2021, 2020 and 2019, was estimated to be $24.99, $25.62 and $19.58 per share, respectively, using the Black-Scholes option-pricing model. The weighted-average assumptions used were as follows:

						2021						2020						2019
Dividend yield						1.32		%				0.99		%				1.23		%
Volatility						27.14		%				20.70		%				21.44		%
Risk-free rate of return						0.75		%				1.41		%				2.53		%
Expected life						6.0 years						6.0 years						6.0 years

Volatility is based on the Company's historic volatility. The risk-free rate of return is based on the yield curve of a zero-coupon U.S. Treasury bond on the date the award is granted with a maturity equal to the expected term of the award. The expected life of the Company’s stock option awards is derived from the simplified approach based on the weighted-average time to vest and the remaining contractual term and represents the period of time that awards are expected to be outstanding.

Performance Stock

In February 2019, 2020 and 2021, the Company's Compensation Committee granted PSUs that were earned based 50% upon a performance condition, measured at each reporting period by earnings per share ("EPS") performance in relation to pre-established targets set by the Compensation Committee, and 50% upon a market condition, measured by the Company’s relative total shareholder return ("TSR") against the S&P 400 Capital Goods Index over a three-year performance period. The fair values of the market conditions are estimated using a Monte Carlo simulation approach in a risk-neutral framework to model future stock price movements based upon historical volatility, risk-free rates of return and correlation matrix.

Deferred Compensation

Prior to 2019, the Company allowed key employees to defer a portion of their eligible granted PSUs and/or compensation into a number of investment choices including its ordinary share equivalents. Any amounts invested in ordinary share equivalents will be settled in ordinary shares of the Company at the time of distribution.

NOTE 16 – RESTRUCTURING ACTIVITIES

During the years ended December 31, 2021, 2020 and 2019, the Company recorded $4.3 million, $25.6 million and $16.5 million, respectively, of expenses associated with restructuring activities. Restructuring activities in each period were primarily associated with the Allegion International segment and related to workforce reductions intended to optimize and simplify operations and cost structure, although approximately $9 million of the restructuring charges incurred during the year ended December 31, 2020, related to the Allegion Americas segment and Corporate. Restructuring expenses for each of the three years ended December 31, 2021, 2020 and 2019, are primarily included within Cost of goods sold and Selling and administrative expenses, although $1.9 million of the 2019 restructuring charges related to pension curtailment costs and are included within Other (income) expense, net within the Consolidated Statements of Comprehensive Income.

The changes in the restructuring reserve during the years ended December 31, 2021 and 2020, were as follows:

In millions																											Total
December 31, 2019																											$	1.2
Additions, net of reversals																											25.0

The Company also incurred other non-qualified restructuring charges of $0.8 million, $1.2 million and $5.7 million during the years ended December 31, 2021, 2020 and 2019, respectively, which represent costs directly attributable to restructuring activities, but that do not fall into the severance, exit or disposal category. Non-qualified restructuring charges are included within Cost of goods sold and Selling and administrative expenses within the Consolidated Statements of Comprehensive Income.

NOTE 17 – OTHER (INCOME) EXPENSE, NET

At December 31, the components of Other (income) expense, net were as follows:

In millions						2021						2020						2019
Interest income						$	(0.4)					$	(0.9)					$	(1.8)
Foreign currency exchange loss						2.7						0.7						1.8

funding round. These gains are included within Other in the table above. Other (income) expense, net for the year ended December 31, 2021, also included a gain of $6.4 million from the sale of the Company's equity method investment in Nuki Home Solutions GmbH.

Other (income) expense, net for the year ended December 31, 2020, included gains of $12.8 million related to the reclassification to earnings of accumulated foreign currency translation adjustments upon the liquidation of two legal entities in the Company's former EMEA segment. These gains are included within Other in the table above.

NOTE 18 – INCOME TAXES

Earnings before income taxes for the years ended December 31 were taxed within the following jurisdictions:

In millions						2021						2020						2019
U.S.						$	74.5					$	151.4					$	211.1
Non-U.S.						449.5						214.0						264.1
Total						$	524.0					$	365.4					$	475.2

The jurisdictional mix of earnings, which includes the impact of the location of earnings as well as the tax cost on the Company's international operations, can vary as a result of operating fluctuations in the normal course of business, the impact of internal restructurings and as a result of the extent and location of other income and expense items, such as restructuring charges, asset impairments and gains or losses on strategic business decisions.

The components of the Provision for income taxes for the years ended December 31 were as follows:

In millions						2021						2020						2019
Current tax expense:
U.S.						$	57.4					$	55.0					$	87.1

The majority of the Company's earnings are considered permanently reinvested, and therefore, the Company has not recorded any incremental withholding or income tax liabilities on earnings of its non-U.S. subsidiaries.

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

In millions						2021						2020
Deferred tax assets:
Inventory and accounts receivable						$	6.5					$	6.5
Fixed assets and intangibles						3.2						2.6

Other						(10.3)						(5.6)
Gross deferred tax liabilities						(157.7)						(147.5)
Net deferred tax assets						$	92.5					$	58.1

At December 31, 2021, $1.9 million of deferred taxes were recorded for certain undistributed earnings of non-U.S. subsidiaries. Historically, no deferred taxes have been provided for any portion of the remaining undistributed earnings of the Company's subsidiaries since these earnings have been, and will continue to be, permanently reinvested in these subsidiaries. For many reasons, including the number of legal entities and jurisdictions involved, the complexity of the Company's legal entity structure, the complexity of tax laws in the relevant jurisdictions and the impact of projections of income for future years to any calculations, the Company believes it is not practicable to estimate, within any reasonable range, the amount of additional taxes which may be payable upon the distribution of earnings.

At December 31, 2021, the Company had the following tax losses and tax credit carryforwards available to offset taxable income in prior and future years:

In millions						Amount						Expiration Period
U.S. Federal tax loss carryforwards						$	17.7					2027-Unlimited
U.S. Federal and State credit carryforwards						23.4						2025-2037
U.S. State tax loss carryforwards						52.1						2022-Unlimited
Non-U.S. tax loss carryforwards						$	1,013.7					2025-Unlimited

The U.S. state loss carryforwards were incurred in various jurisdictions. The non-U.S. loss carryforwards were incurred in various jurisdictions, predominantly in China, Ireland, Italy, Luxembourg and the United Kingdom.

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

F-31

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

In millions						2021						2020						2019
Beginning balance						$	259.7					$	241.0					$	357.1
Increase to valuation allowance						8.4						21.1						2.8
Decrease to valuation allowance						(2.0)						(2.8)						(118.6)
Foreign exchange translation						(0.6)						0.4						(0.3)

During the year ended December 31, 2021, the valuation allowance increased by $5.8 million, while during the year ended December 31, 2020, the valuation allowance increased by $18.7 million. The increases for the years ended December 31, 2021 and 2020, are the result of changes in country specific tax laws, internal restructurings, jurisdictional profitability and changes in judgments and facts regarding the realizability of deferred tax assets.

The Company has total unrecognized tax benefits of $41.5 million and $41.2 million as of December 31, 2021 and 2020, respectively. The amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate is $40.4 million as of December 31, 2021. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:

In millions						2021						2020						2019
Beginning balance						$	41.2					$	37.3					$	42.0
Additions based on tax positions related to the current year						8.8						6.0						5.7
Additions based on tax positions related to prior years						3.6						4.1						1.7
Reductions based on tax positions related to prior years						(2.2)						(1.5)						(7.0)
Reductions related to settlements with tax authorities						(3.6)						(0.3)						(4.0)
Reductions related to lapses of statute of limitations						(5.6)						(5.2)						(0.8)
Translation (gain)/loss						(0.7)						0.8						(0.3)
Ending balance						$	41.5					$	41.2					$	37.3

The Company records interest and penalties associated with the uncertain tax positions within its provision for income taxes. The Company had reserves associated with interest and penalties, net of tax, of $7.5 million and $7.6 million at December 31, 2021 and 2020, respectively. For the years ended December 31, 2021 and 2020, the Company recognized $0.5 million and $1.9 million in interest and penalties, net of tax, related to these uncertain tax positions.

The total amount of unrecognized tax benefits relating to the Company's tax positions is subject to change based on future events including, but not limited to, the settlements of ongoing audits and/or the expiration of applicable statutes of limitations. Although the outcomes and timing of such events are highly uncertain, it is reasonably possible that the balance of gross unrecognized tax benefits, excluding interest and penalties, could potentially be reduced by up to approximately $8.7 million during the next 12 months.

The provision for income taxes involves a significant amount of management judgment regarding interpretation of relevant facts and laws in the jurisdictions in which the Company operates. Future changes in applicable laws, projected levels of taxable income and tax planning could change the effective tax rate and tax balances recorded by the Company. In addition, tax authorities periodically review income tax returns filed by the Company and can raise issues regarding its filing positions, timing and amount of income or deductions and the allocation of income among the jurisdictions in which the Company operates. A significant period of time may elapse between the filing of an income tax return and the ultimate resolution of an issue raised by a tax authority with respect to that return. In the normal course of business, the Company is subject to examination by taxing authorities throughout the world, including such major jurisdictions as Australia, Canada, France, Germany, Italy, Mexico, the Netherlands, Poland and the U.S. In general, the examination of the material tax returns of subsidiaries of the Company is complete for the years prior to 2009, with certain matters being resolved through appeals and litigation.

NOTE 19 – EARNINGS PER SHARE (EPS)

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

F-32

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

In millions						2021						2020						2019
Weighted-average number of basic shares						89.9						92.3						93.6
Shares issuable under share-based compensation plans						0.6						0.5						0.7
Weighted-average number of diluted shares						90.5						92.8						94.3

At December 31, 2021, 0.1 million stock options were excluded from the computation of weighted-average diluted shares outstanding because the effect of including these shares would have been anti-dilutive.

NOTE 20 – NET REVENUES

The following table shows the Company's Net revenues related to both tangible product sales and services for the years ended December 31, 2021, 2020 and 2019, respectively, disaggregated by business segment. Net revenues are shown by tangible product sales and services, as contract terms, conditions and economic factors affecting the nature, amount, timing and uncertainty around revenue recognition and cash flows are substantially similar within each of the two principal revenue streams:

			2021

Total Net revenues			$	2,114.5					$	739.5					$	2,854.0

As of December 31, 2021 and 2020, neither the contract assets related to the Company's right to consideration for work completed but not billed nor the contract liabilities associated with contract revenue were material. The Company does not have any costs to obtain or fulfill a contract that are capitalized on its Consolidated Balance Sheets. During the years ended December 31, 2021 and 2020, no adjustments related to performance obligations satisfied in previous periods were recorded.

NOTE 21 – COMMITMENTS AND CONTINGENCIES

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

Environmental Matters

The Company incurred $0.9 million, $7.1 million and $1.7 million of expenses during the years ended December 31, 2021, 2020 and 2019, respectively, for environmental remediation at sites presently or formerly owned or leased by the Company.

F-33

Environmental remediation costs are recorded in Costs of goods sold within the Consolidated Statements of Comprehensive Income.

As of December 31, 2021 and 2020, the Company has recorded reserves for environmental matters of $16.4 million and $21.1 million, respectively. The total reserve at December 31, 2021 and 2020, included $4.3 million and $4.4 million, respectively, related to remediation of sites previously disposed by the Company. Environmental reserves are classified as Accrued expenses and other current liabilities or Other noncurrent liabilities within the Consolidated Balance Sheets based on the timing of their expected future payment. The Company's total current environmental reserve at December 31, 2021 and 2020, was $3.7 million and $6.1 million, respectively, and the remainder is classified as noncurrent. Given the evolving nature of environmental laws, regulations and technology, the ultimate cost of future compliance is uncertain.

Warranty Liability

The changes in the standard product warranty liability for the years ended December 31, were as follows:

In millions			2021						2020						2019
Balance at beginning of period			$	16.5					$	15.9					$	14.5
Reductions for payments			(10.6)						(7.3)						(8.4)
Accruals for warranties issued during the current period			11.9						8.2						10.3
Changes to accruals related to preexisting warranties			—						(0.6)						(0.4)
Translation			(0.1)						0.3						(0.1)
Balance at end of period			$	17.7					$	16.5					$	15.9

Standard product warranty liabilities are classified as Accrued expenses and other current liabilities or Other noncurrent liabilities within the Consolidated Balance Sheets based on the timing of the expected future payments.

NOTE 22 – BUSINESS SEGMENT INFORMATION

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

As previously announced, effective January 1, 2021, the Company combined its previous operations in Europe, the Middle East and Africa ("EMEA") and Asia Pacific into a new segment named Allegion International, in addition to renaming its Americas segment "Allegion Americas". Business segment information for EMEA and Asia Pacific for the years ended December 31, 2020 and 2019, has been combined in the table below to reflect this change in reportable segments.
