Zero-growth floor

Optimistic top

$76

Arthur J Gallagher & Co (AJG): A conservative value band $40–$76 / sh (zero-growth floor to growth-capped optimistic top); central read about $65. Today’s price sits above that band (price $265 as of 2026-08-26).

The middle figure is the main read. The right end is the optimistic case under the same conservative caps — not an absolute ceiling.

Method & numbers

Operating income is not reported separately (e.g. banks, insurers, and some diversified issuers), so earnings power is shown via the owner-earnings lens only; the unlevered NOPAT lens does not apply.

A conservative intrinsic-value band (zero-growth floor to growth-capped DCF) plus a tangible asset floor — not investment advice, not a buy/sell signal, and not a price target.

Owner-earnings DCF $44.44 – $75.59 · Greenwald zero-growth $47.22 · zero-growth base $47.22 · reproduction $27.65

Moat Franchise (moat) · terminal value 39% of present value · owner-earnings yield 2% vs 10Y 4.7%.

Graham earnings-power value (normalized NOPAT)

Operating income is not reported separately (e.g. banks, insurers, and some diversified issuers), so earnings power is shown via the owner-earnings lens only; the unlevered NOPAT lens does not apply.

Normalized NOPAT from operating margin — not applicable when operating income is not reported separately. Unlevered (pre-interest, attributable to all capital). Capitalized at the 9–11% rate band (read as a WACC proxy). Enterprise → equity bridge (+ cash − total debt) — not applied (lens not assessable).

Years: TTM 2026-06-30, 2024, 2023, 2022, 2021

Buffett owner-earnings value$40.35 – $47.22 / sh

Owner earnings = average net income + average D&A − maintenance capex (zero-growth floor; no ΔNWC). Levered (starts from net income, already after interest — an equity-holder stream). Capitalized at the 11.7–13.7% band (9–11% base + 2.7pp leverage premium). No enterprise→equity bridge: the capitalized result is already equity value (subtracting debt would double-count interest).

Years: TTM 2026-06-30, 2024, 2023, 2022, 2021

v1 simplifications: Maintenance capex or D&A unavailable → degraded to normalized net income (= average net income over the years shown). One-time items are not separately normalized (multi-year averaging smooths them partially). Share-based compensation is left as a real expense (not added back); see the SBC/OE disclosure. Capitalized at the 9–11% base band plus a 2.7pp leverage premium (cost of equity rises with leverage — MM Proposition II). Net debt is about 8.5 years of owner earnings, adding 2.7pp of cost-of-equity risk premium.

Asset floor: Reproduction value = tangible net assets + acquired-intangible reset proxy, ÷ diluted shares; tangible net assets alone are negative for this asset-light franchise (no R&D history to capitalize).

Moat reading: Franchise test compares earnings power (EPV) against reproduction value (tangible net assets + capitalized R&D). EPV well above reproduction value signals a moat; near it, a commodity; below it, value destruction. A directional reading, not a verdict.

Assumes a narrow moat · competitive-advantage period ≈ 10 years.

Growth value not assessable — Operating income is not available across the window, so ROIIC / growth value cannot be computed.

Window TTM 2026-06-30, FY 2024, 2023, 2022, 2021 · discount band 9%–11% · normalized tax 16% (Average effective tax rate over 5 year(s), capped at the statutory 21%.) · diluted shares.

Baseline 9%–11%, net debt ≈ 8.5 years of owner earnings → +2.7pp cost-of-equity premium → effective 11.7%–13.7%.

Owner-earnings DCF: growth g₁ 7% · OE FY TTM 2026-06-30, 2024, 2023, 2022, 2021 · Discount band: 11.91%–14.75% (DGS10 +4.5% to a 12% strict end, each +2.75pp for leverage premium, as of 2026-08-26). No enterprise→equity bridge: owner earnings already flow to shareholders (post-interest), so no net cash is added and no debt subtracted — matching the engine owner-earnings lamp.

Valuation basis: trailing twelve months to 2026-06-30 — latest 10-K plus unaudited 10-Q filings.

What the price is betting

Today's price pencils in about over 30.0% (outside the usual range) a year in owner-earnings for the next few years. Revenue actually grew 14.1% a year.

The market wants it well ahead of its own track record.

Roughly, the price needs its historical revenue growth to run about 34 more years to hold up.
