The majority of the goodwill related to these acquisitions is not expected to be deductible for tax purposes.

The following unaudited pro forma financial information for the three and nine months ended September 30, 2025 and 2024 is subject to change, and reflects the consolidated results of operations of the Company as if these acquisitions had taken place on January 1, 2024:

The unaudited pro forma financial information is presented for informational purposes only and is not intended to be indicative of results of operations that would have occurred had the pro forma events taken place on the date indicated or the future consolidated results of operations of the combined company. The unaudited pro forma financial information does not reflect any synergies or other strategic benefits as a result of the acquisitions. The unaudited pro forma financial information is required under GAAP, and has been calculated after applying the Company's accounting policies and adjusting the historical financial results to reflect additional items directly attributable to the acquisitions that would have been incurred assuming the acquisitions had occurred on January 1, 2024, including amortization of acquired intangible assets, interest costs for debt to fund the acquisitions, and acquisition and integration costs.

Currency Hedging Instruments

The gross notional amount of the Company’s currency derivatives was $349.4 million and $167.2 million at September 30, 2025 and December 31, 2024, respectively. Neither the fair values of currency derivatives, which are determined based on a pricing model that uses spot rates and forward prices from actively quoted currency markets that are readily observable (Level 2 inputs under the fair value hierarchy described in Note 11), nor the balances included in Accumulated other comprehensive loss were material as of September 30, 2025 or December 31, 2024. Currency derivatives designated as cash flow hedges did not have a material impact to Net earnings, Other comprehensive income, or the Condensed and Consolidated Statements of Cash Flows during the nine months ended September 30, 2025 and 2024, nor is the amount to be reclassified into Net earnings over the next twelve months expected to be material. At September 30, 2025, the maximum term of the Company’s currency derivatives 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 therefore, the Company believes they present no significant credit risk to the Company.

Rental expense related to short-term leases, variable lease payments or other leases or lease components not included within the right of use ("ROU") asset or lease liability totaled $12.3 million for the nine months ended September 30, 2025 and 2024. No material lease costs have been capitalized on the Condensed and Consolidated Balance Sheets as of September 30, 2025 or December 31, 2024.

The Company assesses the specific terms and conditions of each lease to determine the appropriate classification as either an operating or finance lease and the lease term. Substantially all of the Company's leases for which the Company is a lessee are classified as operating leases.

Service cost is recorded in Cost of goods sold and Selling and administrative expenses, while the remaining components of Net periodic pension benefit cost (income) are recorded in Other income, net within the Condensed and Consolidated Statements of Comprehensive Income. Employer contributions to the plans were not material during the nine months ended September 30, 2025 or 2024. Employer contributions totaling approximately $3.6 million are expected to be made during the remainder of 2025.

NOTE 11 - 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 three levels that are described below:

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

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

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

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

Assets and liabilities measured at fair value as of September 30, 2025, were as follows:

			Fair value measurements																		Total fair value
In millions			Quoted prices in active markets for identical assets (Level 1)						Significant other observable inputs (Level 2)						Significant unobservable inputs (Level 3)
Recurring fair value measurements

Total financial instruments not carried at fair value			$	—					$	1,979.3					$	—					$	1,979.3

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

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

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

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

The methodologies used by the Company to determine the fair value of its financial assets and liabilities as of September 30, 2025, are the same as those used as of December 31, 2024. The carrying values of Cash and cash equivalents, Accounts and notes receivable, net, Accounts payable and Accrued expenses and other current liabilities are a reasonable estimate of their fair value due to the short-term nature of these instruments.

The Company also had investments in debt and equity securities without readily determinable fair values of $67.3 million and $66.9 million as of September 30, 2025 and December 31, 2024, respectively, which are classified as Other noncurrent assets within the Condensed and Consolidated Balance Sheets. These investments are considered to be nonrecurring fair value measurements, and thus, are not included in the fair value tables above.

NOTE 13 - SHARE-BASED COMPENSATION

The Company’s share-based compensation plans include programs for stock options, restricted stock units ("RSUs") and performance stock units ("PSUs"). Share-based compensation expense is included in Cost of goods sold and Selling and administrative expenses within the Condensed and Consolidated Statements of Comprehensive Income. The following table summarizes the share-based compensation expense recognized for the three and nine months ended September 30:

			Three months ended												Nine months ended
In millions			2025						2024						2025						2024

ALLEGION PLC

NOTES TO CONDENSED AND CONSOLIDATED FINANCIAL STATEMENTS (Continued)

(Unaudited)

The weighted-average fair value of the stock options granted is determined using the Black-Scholes option-pricing model. The following weighted-average assumptions were used during the nine months ended September 30:

			2025						2024
Dividend yield			1.61		%				1.47		%
Volatility			29.89		%				29.29		%
Risk-free rate of return			4.31		%				4.29		%
Expected life (years)			5.4						6.0

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

Performance Stock

During the nine months ended September 30, 2025, the Company granted PSUs with a maximum award level of approximately 0.1 million shares. In February 2023, 2024 and 2025, the Company’s Compensation and Human Capital 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 for each performance period set by the Compensation and Human Capital Committee of the Board, and 50% upon a market condition, measured by the Company’s relative total shareholder return against, for 2023, the S&P 400 Capital Goods Index over a three-year performance period, and for 2024 and 2025, a 50/50 blend of the S&P 400 Capitals Goods Index and the S&P 500 Capital Goods Index over a three-year performance period. The fair values of the market condition 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.

NOTE 14 - OTHER INCOME, NET

The components of Other income, net for the three and nine months ended September 30 were as follows:

			Three months ended												Nine months ended

Other income, net			$	(1.7)					$	(8.4)					$	(10.5)					$	(17.2)

NOTE 15 - INCOME TAXES

The effective income tax rates for the three months ended September 30, 2025 and 2024, were 9.8% and 10.5%, respectively. The decrease in the effective income tax rate compared to 2024 is primarily due to a tax benefit related to the enactment of a tax legislative change, partially offset by the unfavorable year over year changes in amounts recognized for uncertain tax positions.

The effective income tax rates for the nine months ended September 30, 2025 and 2024, were 15.1% and 15.5%, respectively. The decrease in the effective income tax rate compared to 2024 is primarily due to a tax benefit related to the enactment of a tax legislative change, partially offset by the unfavorable year over year changes in amounts recognized for uncertain tax positions.

NOTE 16 - EARNINGS PER SHARE ("EPS")

Basic EPS is calculated by dividing Net earnings 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.

The following table summarizes the weighted-average number of ordinary shares outstanding for basic and diluted EPS calculations for the three and nine months ended September 30:

			Three months ended												Nine months ended
In millions			2025						2024						2025						2024
Weighted-average number of basic shares			85.9						87.1						86.1						87.3
Shares issuable under share-based compensation plans			0.6						0.5						0.5						0.5
Weighted-average number of diluted shares			86.5						87.6						86.6						87.8

At September 30, 2025 and 2024, 0.2 million and 0.3 million stock options, respectively, were excluded from the computation of weighted-average diluted shares outstanding because the effect of including these shares would have been anti-dilutive.

NOTE 17 - NET REVENUES

The following tables show the Company’s Net revenues related to both tangible product sales and services and software for the three and nine months ended September 30, 2025 and 2024, respectively, disaggregated by business segment:

			Three months ended September 30, 2025																		Nine months ended September 30, 2025

Total Net revenues			$	782.4					$	184.7					$	967.1					$	2,262.4					$	564.2					$	2,826.6

(a) Revenue from access control systems and time, attendance and workforce productivity solutions were reclassified from electronic Products revenue to Services and software revenue to better align with the Company's operations and management reporting. The reclassification had no impact on the timing or amount of revenue recognized. Accordingly, the electronic Products revenue and Services and software revenue for the three and nine months ended September 30, 2024 were recast to reflect this change.

Net revenues are shown by tangible product sales and services and software, 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 these two principal revenue streams.

As of September 30, 2025 and December 31, 2024, contract assets related to the Company’s right to consideration for work completed but not billed were not material. The Company does not have any material costs to obtain or fulfill a contract that are capitalized on its Condensed and Consolidated Balance Sheets. During the three and nine months ended September 30, 2025 and 2024, no adjustments related to performance obligations satisfied in previous periods were recorded.

As of September 30, 2025 and December 31, 2024, contract liabilities related to revenues allocated to remaining performance obligations totaled $46.2 million and $33.2 million, respectively, and are classified as Accrued Expenses and other Current Liabilities and Other noncurrent liabilities within the Condensed and Consolidated Balance Sheets. The Company's total current contract liabilities related to revenues as of September 30, 2025 and December 31, 2024 totaled $41.0 million and $28.1 million, respectively, and the remainder was classified as noncurrent.

NOTE 18 - COMMITMENTS AND CONTINGENCIES

The Company is involved in various litigation, claims and administrative proceedings, including those related to environmental and product warranty matters, and the Company also has certain contractual obligations requiring minimum purchases. 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

As of September 30, 2025 and December 31, 2024, the Company had reserves for environmental matters of $23.1 million and $17.8 million, respectively. The total reserve at September 30, 2025 and December 31, 2024, included $9.4 million and $9.9 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 Condensed and Consolidated Balance Sheets based on the timing of their expected future payment. The Company’s total current environmental reserve at September 30, 2025 and December 31, 2024, was $4.6 million and $2.4 million, respectively, and the remainder was classified as noncurrent. Expenses related to environmental remediation were not material during the nine months ended September 30, 2025 or 2024. 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 nine months ended September 30 were as follows:

In millions			2025						2024
Balance at beginning of period			$	22.8					$	20.7
Reductions for payments			(8.8)						(10.4)
Accruals for warranties issued during the current period			8.8						11.6
Changes to accruals related to preexisting warranties			—						(0.6)
Acquisitions			1.7						—
Currency translation			0.6						0.1
Balance at end of period			$	25.1					$	21.4

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

Contractual Obligations

As of September 30, 2025, the Company has arrangements with certain software and information technology service providers that require future minimum purchases of $72.9 million over the remainder of 2025 through 2029.

NOTE 19 - 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. The Company's chief operating decision maker (the "CODM") is its chief executive officer, who uses segment operating income as the measure of profit and loss to evaluate the financial performance of the business and as the basis for resource allocation, performance reviews and compensation. For these reasons, the Company believes that Segment operating income represents the most relevant measure of segment profit and loss. The Company’s CODM may exclude certain charges or gains, such as corporate charges and other special charges, from Operating income to arrive at a Segment operating income that is a more meaningful measure of profit and loss upon which to base operating decisions.

Item 2 – 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 may cause a difference include, but are not limited to, those discussed under Part I, Item 1A – Risk Factors in the Annual Report on Form 10-K for the fiscal year ended December 31, 2024. The following section is qualified in its entirety by the more detailed information, including our Condensed and Consolidated Financial Statements and the notes thereto, which appears elsewhere in this Quarterly Report.

Overview

Organization

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

Recent Developments

Business and Industry Trends and Outlook

In the third quarter of 2025, we delivered low-double digit revenue growth compared to the same period in 2024, driven by favorable pricing and volume growth in the Allegion Americas and Allegion International segments, as well as the impact from acquisitions made during the year.

Demand for electronic security products has also remained strong and continues to be a long-term growth driver. Macroeconomic conditions in our International markets remain mixed.

Global Trade and Macroeconomic Environment

Throughout 2025, the U.S. government announced tariffs on imports from several countries from which we manufacture and/or import products and components. Through the nine months ended September 30, 2025, we have offset inflation due to tariffs with pricing actions. We continue to analyze the impact of changes in tariffs and what, if any, steps, including pricing actions, we may take to mitigate the impact of the tariffs. We estimate we source approximately 20-25% of cost of goods sold ("COGS") from Mexico, less than 5% of COGS from China, and 5-10% of COGS from all other non-US countries. Additionally, this could impact future demand.

Acquisitions

The following acquisitions were completed during the nine months ended September 30, 2025:

On February 4, 2025, we, through our subsidiaries, acquired Next Door Company ("Next Door"), a global provider of security products and solutions based in the United States. Next Door is reported in the Allegion Americas segment.

Net Revenues

Net revenues for the three months ended September 30, 2025, increased by 10.7%, or $103.1 million, compared with the same period in 2024, due to the following:

Pricing			4.0		%
Volume			1.9		%
Acquisitions / divestitures			3.9		%
Currency exchange rates			0.9		%
Total			10.7		%

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

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

Operating Income/Margin

Operating income for the three months ended September 30, 2025, increased $18.8 million compared to the same period in 2024. Operating margin, which we define as Operating income as a percentage of total Net revenues, for the three months ended September 30, 2025, decreased to 21.8% from 22.2% for the same period in 2024, due to the following:

In millions			Operating Income						Operating Margin
September 30, 2024			$	215.0					22.2		%
Pricing and productivity in excess of inflation and investment spending			2.2						(0.6)		%
Volume / product mix			12.7						0.9		%
Acquisitions / divestitures			7.0						(0.2)		%
Currency exchange rates			1.7						—		%
Acquisition / integration / restructuring expenses			(4.8)						(0.5)		%
September 30, 2025			$	233.8					21.8		%

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

The decrease in Operating margin was driven by inflation and investment spending in excess of pricing and productivity, higher acquisition, integration and restructuring expenses, and the unfavorable impact on operating margin from acquisitions/divestitures. These decreases were partially offset by favorable volume/product mix.

Inflation and investment spending in excess of pricing and productivity includes the impact to both Operating income and Operating margin from pricing, as defined above, in addition to productivity, inflation and investment spending. Productivity represents improvements in unit costs of materials, cost reductions related to improvements to our manufacturing design and processes and reductions in selling and administrative expenses due to productivity projects. Inflation includes both unit costs for the current period compared to the average actual cost for the prior period, multiplied by current year volumes, and current period costs of ongoing selling and administrative functions compared to the same ongoing expenses in the prior period. 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 to both Operating income and Operating margin 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.

Interest Expense

Interest expense for the three months ended September 30, 2025, decreased $2.2 million compared with the same period in 2024, primarily due to lower outstanding indebtedness compared to the same period in the prior year.

Other Income, net

The components of Other income, net for the three months ended September 30 were as follows:

In millions			2025						2024
Interest income			$	(2.5)					$	(8.3)
Foreign currency exchange loss			1.2						(0.5)
Other (income) expense			(0.4)						0.4
Other income, net			$	(1.7)					$	(8.4)

Provision for Income Taxes

The effective income tax rates for the three months ended September 30, 2025 and 2024, were 9.8% and 10.5%, respectively. The decrease in the effective income tax rate compared to 2024 is primarily due to a tax benefit related to the enactment of a tax legislative change, partially offset by the unfavorable year over year changes in amounts recognized for 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 reviews our financial performance and makes operating decisions.

Segment operating income is the measure of profit and loss that our 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, we believe that Segment operating income represents the most relevant measure of Segment profit and loss. Our chief operating decision maker 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.

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 operating activities, our unused borrowing capacity under the Revolving Facility and our access to the capital and credit markets enable us to fund these capital needs, execute our long-term growth strategies and return value to our shareholders. Further, our business operates with strong operating cash flows, low leverage and low capital intensity, providing 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 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 September 30, 2025, approximately 86% 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 borrowing capacity under the Revolving Facility, as of September 30, 2025, we expect our cash flows from operations will be sufficient to maintain a sound financial position and liquidity and to meet our current 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 borrowing capacity under the 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 nine months ended September 30. For additional details, see the Condensed and Consolidated Statements of Cash Flows in the Condensed and Consolidated Financial Statements.

In millions			2025						2024
Net cash provided by operating activities			$	543.7					$	456.0
Net cash used in investing activities			(649.3)						(190.2)
Net cash (used in) provided by financing activities			(115.2)						147.3

Operating Activities: Net cash provided by operating activities during the nine months ended September 30, 2025, increased $87.7 million compared to the same period in 2024, primarily driven by less cash used for working capital and higher net earnings.

Investing Activities: Net cash used in investing activities during the nine months ended September 30, 2025, increased $459.1 million compared to the same period in 2024, primarily due to higher cash used for acquisitions.

Financing Activities: Net cash used in financing activities during the nine months ended September 30, 2025, increased $262.5 million compared to the same period in 2024. Net proceeds from debt borrowings were $306.6 million lower year over year due to the timing of the issuance of the $400 million 5.600% Senior Notes in May 2024. The proceeds from the 5.600% Senior Notes were used to repay senior notes that matured in October 2024. Net proceeds from the debt borrowings in 2025 were $83.3 million and were used to partially fund the acquisitions completed during the year. Additionally, repurchases of ordinary shares were $40 million lower than the prior year period.

We have an unsecured credit agreement in place, consisting of a $250.0 million term loan facility (the “Term Facility”), of which $196.9 million was outstanding at September 30, 2025, and a $750.0 million revolving credit facility (the “Revolving Facility” and, together with the Term Facility, the “Credit Facilities”), of which $99.0 million was outstanding at September 30, 2025.

The Term Facility requires quarterly principal payments through its maturity on November 18, 2026. Future payments total $6.3 million for the remainder of 2025 and $190.6 million in 2026. We repaid $15.6 million of principal on the Term Facility during the nine months ended September 30, 2025. The Revolving Facility matures on May 20, 2029 and includes up to $100.0 million for the issuance of letters of credit. We had $18.7 million of letters of credit outstanding at September 30, 2025. Borrowings under the Revolving Facility are due upon its maturity but may be repaid at any time without premium or penalty, and amounts repaid may be reborrowed.

Outstanding borrowings under the Credit Facilities accrue interest, at our option, equal to either: (i) a Secured Overnight Financing Rate ("SOFR") plus an 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 September 30, 2025, our outstanding borrowings under the Credit Facilities accrued interest at SOFR plus a margin of 1.225%, resulting in an interest rate of 5.388%. The Credit Facilities also contain 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 Facilities require us to comply with a maximum leverage ratio as defined in the credit agreement. As of September 30, 2025, we were in compliance with all applicable covenants under the credit agreement.

As of September 30, 2025, we also have $400.0 million outstanding of 3.550% Senior Notes due 2027 (the “3.550% Senior Notes”), $600.0 million outstanding of 5.411% Senior Notes due 2032 (the “5.411% Senior Notes”), $400.0 million outstanding of 5.600% Senior Notes due 2034 (the "5.600% Senior Notes"), and $400.0 million outstanding of 3.500% Senior Notes due 2029 (the “3.500% Senior Notes”, and all four senior notes collectively, the "Senior Notes"). The 3.550% Senior Notes and 3.500% Senior Notes both require semi-annual interest payments on April 1 and October 1 of each year and mature on October 1, 2027 and October 1, 2029, respectively. The 5.411% Senior Notes require semi-annual interest payments on January 1 and July 1 of each year and mature on July 1, 2032. The 5.600% Senior Notes require semi-annual interest payments on May 29 and November 29 of each year and mature on May 29, 2034.

Historically, the majority of our earnings were considered to be permanently reinvested in jurisdictions where we have made, and intend to continue to make, substantial investments to support the ongoing development and growth of our global operations. At September 30, 2025, we analyzed our working capital requirements and the potential tax liabilities that would be incurred if certain subsidiaries made distributions and concluded that no material changes to our historic permanent reinvestment assertions are required.

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. For further details on pension plan activity, see Note 10 to the Condensed and Consolidated Financial Statements.

Guarantor Financial Information

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

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

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

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

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

Critical Accounting Policies

Management’s Discussion and Analysis of Financial Condition and Results of Operations are based upon our Condensed and Consolidated Financial Statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of financial statements in conformity with those accounting principles requires management to use judgments 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, revenue 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.

Management believes there have been no significant changes during the nine months ended September 30, 2025, to the items we disclosed as our critical accounting policies in "Management’s Discussion and Analysis of Financial Condition and Results of Operations" in our Annual Report on Form 10-K for the year ended December 31, 2024.

These statements are based on currently available information and our current assumptions, expectations and projections about future events. While we believe that our assumptions, expectations and projections are reasonable in view of the currently available information, you are cautioned not to place undue reliance on our forward-looking statements.
