How Does Allegion Make Money?
Alle_Allegion Americas supplies 79% of revenue, so Allegion's results move mostly with that one business; the others matter more for diversification than for the headline number. Between fiscal 2024 and 2025, Allegion International grew fastest (+11.7%) and Alle_Allegion Americas slowest (+6.9%), so the revenue mix tilts toward Allegion International while that gap lasts.
| Segment | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
|---|---|---|---|---|
| Alle_Allegion Americas | $3.2 billion | $3.0 billion | 79.1% | 6.9% |
| Allegion International | $849 million | $760 million | 20.9% | 11.7% |
Which Allegion Segments Earn the Most?
| Segment | FY2025 segment operating income | Segment margin |
|---|---|---|
| Alle_Allegion Americas | $897 million | 27.9% |
| Allegion International | $77 million | 9.0% |
Segment operating income is the profit measure Allegion reports to its chief operating decision maker for each segment. It usually leaves out corporate costs that are not allocated to a segment, so the segments usually add up to more than consolidated operating income, and margins are comparable within Allegion more safely than against another company.

| Electronic Products | $1.1 billion | $946 million | 26.4% | 13.6% |
| Service | $278 million | $254 million | 6.8% | 9.7% |

| Region | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
|---|---|---|---|---|

| Outside the United States | $1.0 billion | $914 million | 25.0% | 11.4% |
What the Segment Figures Do Not Show
The rows above add up to 100% of Allegion's reported revenue for fiscal 2025; the difference is intersegment eliminations, corporate revenue or items the company reports outside its segments. Segment definitions are management's choice and change when a company reorganizes, in which case it restates prior years in the next filing, so a multi-year comparison should use the figures from a single filing. Revenue shows where sales come from, not where profit or cash is earned: a small segment can carry most of the margin.
Where These Numbers Come From
Every figure on this page is a value Allegion reported in the segment note and revenue disclosures of its Form 10-K filed February 17, 2026 (accession 0001579241-26-000007), read from the SEC's Financial Statement Data Sets. The prior-year column is the comparative figure from that same filing, so it reflects any restatement for a change in segments. Category names are the company's own XBRL labels, lightly reformatted for reading.
Rows that only total other rows (for example a "Products" line beside the individual products) are left out so nothing is counted twice. This page is educational and describes reported history for fiscal 2025; it is not a forecast or a recommendation.
