Allegion (ALLE)
Forward P/E is 18.28x against a peer median of 16.35x, a ratio of 1.12x — inside the 0.90–1.15 fairly priced band, near its top — with trailing P/E 22.62x and PEG 1.86. Latest-quarter revenue grew 9.6% year over year (PRIMARY, EDGAR), matching the cluster median, so the small premium stays within the fair band. Delivered demand check: the Electrical equipment & building products group's median growth was 9.6% year over year — demand rising, and this company is growing at that pace.
What would change this label: Move to OVERVALUED if the forward P/E rises to about 18.8x or above (1.15x the peer median) at unchanged estimates, or if revenue growth falls below 3% year over year for two quarters. Move to UNDERVALUED if the forward P/E compresses to about 14.7x or below (0.90x the peer median) at unchanged estimates while revenue growth stays at or above the group pace.
Allegion makes locks, door hardware and electronic security products for buildings. Its shares trade at about 18 times expected earnings, a small premium to similar companies, while sales grew about 10% in the latest quarter, matching the wider group. That combination makes the price look fair — the small premium is backed by solid growth.
Both lines start at 100 on 2020-09-01. Over the full window Allegion returned +76.84% and the S&P 500 +118.28% (price returns; dividends not reinvested). Worst peak-to-trough fall for Allegion: -39.9% (2021-09-03 to 2022-09-27). Source: Nasdaq official daily history.

Multiples: stockanalysis.com (SECONDARY, S&P Global data), fetched Oct 28, 2026. Peer set chosen by sector; the median is the middle value of the set. The label and its numbers were recorded in the programme’s label registry on Oct 28, 2026 and will be scored at 6 and 12 months.
Sales, profit and cash
This company does not report a gross-profit line in its SEC facts (normal for banks, payment networks and some health insurers), so profit is shown as net income instead — gross margin is marked UNVERIFIED-absent rather than estimated.
Free cash flow = cash from operations minus spending on plant and equipment, both from the company’s SEC cash-flow statement. Gaps are quarters where that spending line is not separately tagged in the filings — shown as gaps, never estimated.

The last twelve reported quarters. Full 25-quarter history sits in the data pack behind this page. A dash means the figure is not tagged as a standalone quarter in the company’s SEC facts (the usual case is the fourth quarter, which many companies only report inside the full-year filing) — it is missing, not zero.
Earnings: getting better or worse?
Each box is one quarter’s earnings per share (EPS). Green means EPS was higher than the same quarter a year earlier; red means lower; a dash means the figure is not tagged in the filings.
Basis: GAAP diluted EPS from SEC company facts, compared with the same quarter a year earlier.

What we could not verify
- Gross profit / gross margin: not tagged as a standalone line in this company's EDGAR company facts (common for banks, payment networks and some healthcare payers) — shown as UNVERIFIED-absent; the page charts revenue and net income instead.
- TTM GAAP diluted EPS could not be summed from company facts because at least one of the last four quarters (typically Q4) has no standalone tagged EPS; trailing P/E is therefore taken from the labelled secondary source in valuation_label.md.
- Own-history P/E (5-year median): not computed in the Phase 1 batch — UNVERIFIED
- Guidance record (each quarter scored against the guidance the company gave the quarter before) is not yet compiled for this company — it is a Phase 2 layer. The earnings strip below therefore uses reported EPS versus a year earlier, which is fully sourced from filings.
The IT factor — the most exciting thing the market is overlooking — is not assessed on an X-Ray page. It belongs to the Deep Dive (Phase 2), where it gets the evidence standard it needs. Leadership-era scoring (the six years split by chief executive) is likewise a Phase 2 layer; this page names the current chief executive only, from a sourced profile.
