Marsh & Mclennan Cos (MRSH): Two methods value the business — a conservative owner-earnings DCF and a growth-credited Greenwald estimate, $54–$172 / sh. Today’s price sits above both (price $193 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

Model cautions

The two methods’ midpoints differ materially — growth assumptions warrant review (over 20%).

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 $77.83 – $137.88 · Greenwald $121.79 – $172.46 (neutral $146.38) · zero-growth base $90.29 · reproduction $2.08

Moat Franchise (moat) · terminal value 45% of present value · owner-earnings yield 5% vs 10Y 4.7%.

Graham earnings-power value (normalized NOPAT)$54.39 – $75.17 / sh

Normalized NOPAT = average operating margin over the years shown × latest-year revenue × (1 − normalized tax); then + D&A − maintenance capex (write A). Unlevered (pre-interest, attributable to all capital). Capitalized at the 9–11% rate band (read as a WACC proxy). Enterprise → equity bridge applied: + cash − total debt.

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

v1 simplifications: Maintenance capex (degraded) deducted in full cash (write A): EPV = (NOPAT + D&A − maintenance capex) / WACC; no tax shield on the capex term. Maintenance-capex methods diverge by 160% (> 50%); estimate is degraded. Share-based compensation is left as a real expense (not added back). Operating margin is below its multi-year average (cyclical/declining): normalized margin capped at the latest year — no peak-margin capitalization (audit #2).

Buffett owner-earnings value$74.89 – $90.29 / 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 9.7–11.7% band (9–11% base + 0.7pp 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: Owner earnings = net income + D&A − maintenance capex (degraded); the working-capital change is excluded (maintenance ΔNWC ≈ 0; growth ΔNWC is carried in growth value, not double-counted). Maintenance-capex methods diverge by 160% (> 50%); estimate is degraded. 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 0.7pp leverage premium (cost of equity rises with leverage — MM Proposition II). Net debt is about 4.5 years of owner earnings, adding 0.7pp 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: if the moat holds for 10 yr at ROIIC ≈ 293%, $31.50–$82.18 / sh (neutral $56.10). Conservative, not a forecast.

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

Baseline 9%–11%, net debt ≈ 4.5 years of owner earnings → +0.7pp cost-of-equity premium → effective 9.7%–11.7%.

Owner-earnings DCF: growth g₁ 5% · OE FY TTM 2026-06-30, 2024, 2023, 2022, 2021 · Discount band: 9.89%–12.73% (DGS10 +4.5% to a 12% strict end, each +0.73pp 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. Two-method midpoint gap 24%.

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 14.7% a year in owner-earnings for the next few years. Revenue actually grew 8.8% a year.

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

Roughly, the price needs its historical revenue growth to run about 21 more years to hold up.
