Allegion PLC (ALLE)

Investment Committee Summary

Investment Thesis

At $163 (25 August 2026) Allegion trades on 18 times forward earnings, a marked discount to its building-products peer median, implying the market treats it as a low-growth hardware cyclical rather than a compounding security franchise. The engine largely agrees with the market, not the peer set: the discounted-cash-flow work and the Monte Carlo median both sit beneath the current price, and only a minority of simulated paths finish above it. The probability-weighted value of $136 and the base-path target of $137 sit well below spot, and triangulated fair value of $125 leaves the shares trading rich to the anchor set, -23% against spot. The peer-multiple anchors are the outliers; the engine reads the gap as a discount worth monitoring, not an entitlement, because the valuation is carried by margin and multiple rather than growth — variance decomposition puts most outcome dispersion in the earnings multiple and much of the balance in gross margin. Capital intensity is light on an operating margin of 22% and net debt of ~$1.7B, so cash conversion is not the debate. The rating is SELL. The single most damaging risk is the structural scenario — a construction-demand reset combined with substitution pressure — which prices the shares far below the 52-week low.

Narrative drafted 2026-08-16 by claude-opus-5 under supervision; reviewed by Marinus 2026-08-16.

The dashboard below is the whole argument on one page: spot ($163) against each valuation anchor, the scenario tree, technicals and the options-implied move.

Anti-Thesis (The Real Bear Case)

The structural bear is not a cycle call. Allegion earns an operating margin of 22% on mechanical locks and door hardware supplied into a consolidating channel while the installed base goes electronic. If access control migrates to software-defined credentials, the moat shifts from brass and specification relationships to platforms — territory where better-capitalised electronics and cloud players set the economics and hardware becomes the commodity layer. Layer a genuine nonresidential reset on top, with datacentre and institutional construction normalising after the recent surge, and volume, price and mix retreat together. Margins compress towards the mid-teens, the multiple follows from 18 times toward the low double digits, and the equity clears at the structural target — below the 52-week low, a level the recent range has never tested.

Key Debate

P/E Multiple explains 63% of Monte Carlo outcome variance — i.e. value is set by the multiple the market will pay, a rate/sentiment regime bet as much as an earnings bet.

What the Market Is Pricing In

At the current price, the market pays 18.2× consensus forward EPS, vs the house DCF terminal 13.0×, and a peer median 25.8×. The house DCF sits 27% below spot, so the market is pricing in more than the house case — roughly 2.7pp of revenue CAGR.

Variant perception: the house view is below-consensus, and the thesis is primarily event-driven.

Scenario Analysis

The scenario tree spans a structural 'Structural — Construction-Demand Reset / Substitution' downside ($59.40) to a 'Bull — Re-Rate' bull case ($240); the probability-weighted blend (PWEV $136) is -17% versus spot.

Share-count charge: none applied. The probability-weighted value above is the gross per-share figure — no annual dilution is deducted — stock-based compensation runs at 0.7% of revenue; free cash flow net of SBC is $0.66B. SBC is therefore disclosed, not charged: read the per-share figures as before dilution.

Scenario rationale — the driver path behind every target:

• Structural — Construction-Demand Reset / Substitution (20%, $59.40). Structural impairment — construction-demand reset / substitution: earnings AND the multiple compress together. Target sits below the 52-week low by construction.
• Housing / Nonres Recession (17%, $100). Cyclical downturn — new-build + repair-remodel volumes + price/mix vs input costs weakens for 1–2 years before normalising.
• Base — Repair-Remodel + Pricing (35%, $140). Mid-cycle — normalised new-build + repair-remodel volumes + price/mix vs input costs; disciplined capital allocation; steady returns.
• Growth — Datacenter Cooling / Electrification / Reno (20%, $191). Upside — renovation cycle + efficiency upgrades + non-res build lifts earnings above mid-cycle; the multiple expands modestly.
• Bull — Re-Rate (8%, $240). Upside tail — sustained tight conditions or a structural re-rate on renovation cycle + efficiency upgrades + non-res build.

Valuation Triangulation

Three weighted anchors — an intrinsic dcf, a scenario-weighted pwev and a monte carlo median (student-t + regime switching) — read them with their basis in mind. The Monte Carlo, the DCF terminal and any peer re-rate key off a market multiple, so they are not fully independent; only discounted cash flows themselves are genuinely multiple-free. The discipline is to read the spread and weight the cash-based view, not to treat three numbers as three independent votes.

The house blend DECLARES five anchor weights — DCF 35%, scenario PWEV 25%, Monte Carlo 15%, sum-of-parts 15%, peer re-rate 10%. For this name sum-of-parts, peer P/E re-rate are not computed, so 25% of the declared weight is redistributed across the anchors that exist — which is why the weights above differ from the declared ones. The fair value is unaffected by this disclosure; the blend has always worked this way.

Peer EV/Revenue re-rate — 0% weight: it duplicates the peer-multiple information already carried by the Peer P/E anchor while ignoring margin mix; weighting both would double-count the peer view. Shown as a cross-check.

Monte Carlo — the outcome distribution

10,000 paths, Student-t shocks (fat tails) with a regime-switching overlay. The median lands at $124 and 24% of paths finish above spot. The variance decomposition shows the p/e multiple is the dominant swing factor (63% of variance). Value is a multiple bet: fundamentals move the answer far less than the rating does.

DCF — the cash-flow anchor

Independent of the market multiple: a 5-year path, WACC 8.5%, 13.0x terminal FCF multiple → $118. This anchor is deliberately the heaviest (47%): it is the valuation least hostage to the current multiple regime.

Peer benchmarking — relative value

Against the peer cohort, re-rating to the peer-median EV/Revenue multiple implies $187; the peer-median forward P/E is 25.8x, but the engine carries no P/E-implied price for this name (no forward-EPS basis at the peer step). A premium is only justified by superior growth/margins; otherwise it is multiple risk. Excluded from the weighted blend — shown only as a market cross-check.

Across all anchors the spread is 51% of the median — wide (genuine disagreement — the blend carries low valuation confidence).

Sensitivity

DCF/share — WACC × terminal multiple

DCF/share — revenue CAGR Δ × op-margin Δ

Tornado — DCF/share swing by driver (widest first)

Company lever — SoP/share vs Building Products multiple (AI re-rating) (base 15.0x)

Peer Quality & Weighting

Quality-weighted forward P/E: 26.2× (simple median 25.8×). Direct peers count 100%, segment 50%, broad 25%.

Historical-range cross-check: 52-week range $124–$182, centre $150 (-8% vs spot); spot sits at the 67th percentile of the range. Low-weight mean-reversion cross-check, not a fundamental anchor.

Risk / Reward & Margin of Safety

That ratio compares triangulated upside against the probability-weighted bear target, not the extreme tail; with a leg missing it is withheld rather than computed from a magnitude. Bull case (Bull — Re-Rate): $240.

Company Overview & Business Model

Allegion PLC — INDUSTRIALS · SECURITY & PROTECTION SERVICES. Allegion plc is an American-Irish provider based in Dublin of security products, for homes and businesses. It comprises thirty one global brands, including CISA, Interflex, LCN, Schlage and Von Duprin.

How it makes money.

Edge. Wide moat — Allegion's moat is wide within its niche: entrenched specification (spec-writers write Schlage/Von Duprin into building codes and designs), fire/life-safety code compliance, and a large installed base of mechanical and electronic access hardware with high replacement/spec stickiness. A wide but niche moat supports a premium to a plain cyclical - yet the market prices it at ~15x vs. a 25.8x peer median, treating it as low-growth hardware; the terminal multiple should re-rate toward peers if electronic-access/software attach lifts growth, or stay depressed if it remains mechanical replacement demand - falsified if the electronics/software mix drives sustained high-single-digit organic growth.

Scenario Macro & Key Risks

Decision Rules (Machine-Checked)

Stance: Hold — 0 bullish / 1 bearish / 0 caution rules triggered of 6 evaluable (0 lacked data).

Machine-checked rules over disclosed inputs. The authored falsification triggers elsewhere in this report are analyst judgment and are NOT evaluated here. The stance is a portfolio-management signal and does not modify the published research rating.

Reasons the Thesis Could Fail (Falsifiable)

Pre-registered signals that would break the thesis — each polices a specific scenario boundary and is checked at every earnings update:

• Total organic revenue growth (YoY) < 0.01 (2 consecutive prints). (rationale withheld pending re-authoring — frozen figure or verdict)
• Adjusted operating margin < 0.204 (2 consecutive prints). (rationale withheld pending re-authoring — frozen figure or verdict)
• Americas segment organic revenue growth (YoY) < 0.0 (2 consecutive prints). The Americas nonresidential and institutional channel carries the profit pool. Two consecutive organic declines there would show the nonres backlog rolling over rather than a soft patch, invalidating the mid-cycle base assumption.
• FY adjusted EPS guidance < 8.9 (single event). (rationale withheld pending re-authoring — frozen figure or verdict)
• Net debt / EBITDA > 3.0 (single event). (rationale withheld pending re-authoring — frozen figure or verdict)

Fact / Inference / Speculation

• FACT: Spot $163; 52-week range $124–$182; engine rating SELL; house target $137 (-16%). (source: Alpha Vantage 2026-08-24, 25 August 2026)
• INFERENCE: Triangulated FV $125 (-23% vs spot · triangulated FV); the rating tracks the Monte-Carlo + scenario-PWEV core; the cash-flow anchor sits below the multiple-discipline core.
• SPECULATION: At current prices the embedded bet is that the market keeps paying the current multiple through the capex cycle — a regime call the engine cannot verify from fundamentals alone.

Conviction Score

Research Conviction measures the strength and quality of the research setup — input coverage, financial quality, valuation support, process agreement. It is NOT the probability that the recommendation succeeds; the forecast track record section is the evidence on that.

61.8/100 (confidence band 49.9–73.8), 66th percentile of 858 covered names (as of 2026-08-24). Weighted composite under config ros-1.19.0 — every component and its inputs below.

Missing inputs (macro tailwinds) are excluded and the remaining weights renormalised; the confidence band widens accordingly.

Score history: 62.3 → 62.3 → 62.6 → 62.5 → 62.5 → 62.6 → 62.2 → 62.2.

Probability-Weighted Return Profile

Horizon: 1 year — at this horizon CAGR equals total return by definition. Expected values are the probability-weighted sums over the full scenario set below.

The gross expected return is the probability-weighted scenario return (it reconciles to the gross PWEV); the diluted figure applies the SBC share-count charge and matches the published PWEV-based target.

Expected Alpha

Expected return minus the return this name is REQUIRED to deliver for its risk (1-year horizon). Constants are pre-registered (preregistered-static (amendment #2, 2026-07-29); not fitted to MCH outcomes).

A negative expected alpha does not change the rating — it says the expected return does not clear the risk-adjusted hurdle at today's price. Rating mechanics are unchanged by this section.

Probability Cross-Checks

Not authoritative. The scenario probabilities in this report are AUTHORED — a judgement about how the world might go, not a measurement. Nothing below modifies them, the target, the rating or any position size. These checks ask only whether anything outside our own model agrees with us; where it does not, that is information for the reader, not a correction we have quietly applied.

Authored set: 5 scenarios, probabilities summing to 1.0, mean target $135.5.

Factor Exposures

Cross-sectional percentiles over 858 covered names (style scores sector-demeaned; thematic = return-beta to the theme's proxy ETF). 50 = estate median.

Market interaction: correlation vs SPY +0.42, vs QQQ +0.30 (trailing ~1y daily returns).

Options Intelligence

Preferred structure: Put Debit Spread. The selector reads the equity view (direction) and the volatility surface — nothing here re-prices the chain.

• bearish with cheap options — buy defined-risk downside
• Direction bearish from the overlay conviction/rating (read-only input).
• IV/RV at the 11th percentile of the cross-section → low vol bucket. This is the measure that selects the structure above: it ranks how rich this name's implied vol is against its own realised vol, relative to other names.
• Reported alongside and not used to select: this name's own ATM IV sits at the 79th percentile of its own month-end history (decile 8). The two measures disagree here — vol is high for this name by its own history while its options are not unusually rich against its realised vol. Where they diverge, the cross-sectional measure is the one acting.

IV term structure (flat, slope +0.0pp): 25-DTE 28% · 116-DTE 29% · 207-DTE 28%

Options Overlay

A defined-risk way to express the SELL equity view. Chain as of 2026-08-24 — end-of-day marks — indicative, not executable quotes.

Market signals — ATM IV 27.8% (moderate regime) · expected move ±5.6% (2026-09-18) · put/call OI 0.16 · ATM Δ 0.44 / Θ -0.09 / ν 0.17 · next earnings 2026-10-22. Direction: SHORT/HEDGE (implied return -23.1% to triangulated fair value $125.08).

Bear Put Spread (Bearish) — Long 165 P / Short 125 P · 2027-03-19 · net debit $11.9 · max profit $28.10 · breakeven $153.10 · RoR 236.0% · max loss $11.90 · priced from the listed chain (EOD marks)

Defined-risk downside expression: the debit caps the loss, with the position gaining as the stock falls toward the lower strike — a way to act on a bearish view without shorting stock. Illustrative — no outcome is implied or guaranteed.

Protective Put (if held) (Hedge) — Long 165 P · 2027-03-19 · premium $13.15 · floor 1.0% · max loss $13.15 · priced from the listed chain (EOD marks)

Insurance for an existing holding — a known premium buys a floor while leaving the upside intact. A way to hold through a binary event or volatility with defined downside.

Protective Collar (if held) (Hedge) — Long 145 P / Short 180 C · 2027-03-19 · net $2.35 · floor -11.0% · cap +11.0% · priced from the listed chain (EOD marks)

For a holder who wants to stay invested but cap risk: the sold call funds most of the protective put, fencing the position into a band — a way to ride out a de-rating without selling.

Indicative options structures — a defined-risk expression of the equity view, model-and-market illustrated from the last-close chain. NOT personalised advice or an executable quote; premiums, IV and greeks move intraday. Options carry the risk of total loss of premium. Not a registered financial adviser.

Rating Bridge

Rating = SELL because:

• Probability-weighted scenario value implies -17% vs spot
• Monte Carlo median implies -24% vs spot
• DCF fair value implies -27% vs spot — but this is terminal-value sensitive (exit-multiple $118 vs Gordon $149, 26% apart), so it carries less weight
• Bear case (Structural — Construction-Demand Reset / Substitution) downside is -63% vs spot
• Net: the valuation anchor itself sits 23.1% below spot, so there is no reward leg to weigh against the bear case and the reward-to-risk ratio is withheld rather than computed off a negative upside. The rating warrants a Sell.

Model Appendix

DCF — line items

FCF is bridged: NOPAT + D&A − Capex − ΔNWC (capex intensity 3% of revenue, weighted from the segments) — not a single conversion fudge.

WACC 8.5% · Σ PV(FCF) $3B + PV(terminal) $8B = EV $11B; − net debt $1.7B → equity $10B ÷ diluted shares $0.08B = $118/share (exit-multiple terminal).

• Gordon terminal at 2.5% → $149/share — a genuinely non-multiple, cash-based cross-check; the exit-multiple and Gordon values bracket the terminal-value risk.
• Incremental ROIC on the forecast capex ≈ 30% vs WACC 8.5% → above WACC — the build is value-creative.

Peer set

Implied prices at the peer medians: EV/Rev → $187 (no P/E-implied price — no forward-EPS basis at the peer step).
