DUBLIN (April 28, 2026) – Allegion plc (NYSE: ALLE), a leading global security products and solutions provider, today reported financial results for its first quarter (ended March 31, 2026).

“Allegion delivered strong Q1 revenue growth led by our Americas non-residential and electronics businesses,” Allegion President and CEO John H. Stone said. “Our team remains agile, proactively managing inputs to offset external pressures in a volatile macro environment. I’m especially proud of our people and our culture, recognized with our third Gallup Exceptional Workplace Award in March of this year.”

Q1 2026 Company Results

(All comparisons are year-over-year, unless otherwise noted)

Allegion reported first-quarter 2026 net revenues of $1,033.6 million and net earnings of $138.1 million, or $1.59 per share. Adjusted net earnings were $155.9 million, or $1.80 per share, down 3.2%. (Details of the adjustments are included in the footnotes of the tables in this press release.)

First-quarter 2026 net revenues increased 9.7%. On an organic basis, which excludes impacts of acquisitions, divestitures and foreign currency movements, net revenues increased 2.6%, led by the Americas region. The organic revenue increase was driven by price realization partially offset by volume declines. Reported revenue reflects a 4.8% net positive impact from acquisitions and divestitures, as well as a 2.3% tailwind from foreign currency.

First-quarter 2026 operating income was $195.3 million, a decrease of $1.1 million or 0.6%. Adjusted operating income in first-quarter 2026 was $218.9 million, an increase of $5.5 million or 2.6%.

First-quarter 2026 operating margin was 18.9%, compared with 20.9%. The adjusted operating margin in first-quarter 2026 was 21.2%, compared with 22.7%. The adjusted operating margin decline is attributable to headwinds from volume declines and price and productivity net of inflation and investment (PPII), inclusive of transactional foreign currency, which was positive on a dollar basis but a headwind to margin rate.

Q1 2026 Segment Results

(All comparisons are year-over-year, unless otherwise noted)

The Americas segment revenues were up 6.9% (up 4.5% on an organic basis). The non-residential business was up mid-single digits organically, driven by price realization. The residential business was flat organically, with price realization offsetting volume declines. The reported revenue reflects a 2.1%

positive impact from acquisitions and a slight tailwind from foreign currency. Adjusted operating margin in the region decreased 110 basis points to 28.1% due to volume declines in the residential business and unfavorable mix. PPII, inclusive transactional foreign currency headwinds, was positive on a dollar basis but a headwind to margin rate. Acquisitions were also a 40-basis point headwind to margin rate.

The International segment revenues were up 21.5% (down 5.3% on an organic basis). The organic revenue decrease was primarily driven by volume declines related to disruptions from an ERP implementation in one of the company's legacy mechanical businesses, partially offset by price realization. Reported revenue reflects a 15.9% net positive impact from acquisitions and divestitures and a 10.9% tailwind from foreign currency. Adjusted operating margin in the region decreased 220 basis points to 8.0%, driven by volume declines and a PPII headwind, offset by favorable impacts from acquisitions. The margin rate decline was primarily driven by the ERP implementation previously mentioned. Production rates in the affected legacy mechanical business are improving, and we expect to recover the ERP production related shortfall over the remainder of 2026, as supported by existing orders and backlog.

Additional Items

(All comparisons are year-over-year, unless otherwise noted)

Interest expense for first-quarter 2026 was $24.2 million, a decrease of $0.5 million.

Other income, net for first-quarter 2026 was $0.4 million, compared to other income, net of $3.5 million.

The company’s effective tax rate for first-quarter 2026 was 19.5%, compared with 15.4%. The company’s adjusted effective tax rate for first-quarter 2026 was 20.1%, compared with 16.1%.

Cash Flow and Liquidity

Year-to-date available cash flow for 2026 was $80.3 million, a decrease of $3.1 mill
