The essentials

  • Global leader as stated in the company's own 10-K: "the world's largest insurance broker and risk advisor," present in 130 countries with more than 95,000 colleagues.
  • Capital-light model: TTM capex is only about 1.1% of revenue; growth is financed almost entirely with operating cash, with no material operating leverage.
  • Recent reported growth (FY2025 +10.3%, TTM +8.3%) is inflated by the McGriff acquisition (Nov-2024, US$7.75bn); underlying organic growth runs around 4-5% per year.
  • Returns nearly all free cash flow to shareholders via a growing dividend and share buybacks (~2% annual reduction in share count).

Intrinsic value — two valuation methods

Fairly valued
Price market

DCF value today

Multiples value today

+27.7% vs price

Total return at 5 years: 10.0%/year = 7.4% appreciation + 2.6% dividend. The target price ($252) is ex-dividend; the $27 in dividends collected over 5 years are added separately.

By both methods, the value today (DCF $240 · Multiples $225) exceeds the market price ($177).

Pillars of the analysis

The verdict — today vs 5 years

Today — fairly valued: at $177 trades ~21.7% below its value discounted to today (~$225); the discount is positive but does not reach the margin of safety we require (≥38%).

At 5 years — En valor: the target price ($252) plus dividends yield between the 4% floor and the 10% average return — a reasonable return, though without the margin of a great investment.

The bridge: the return at 5 years exceeds the risk-free rate (4.5%) — but the discount does not reach the required margin of safety (≥38%). To require a 15% annual return, it would need to be bought at ~$143.

Thesis

The business

Global leader in insurance brokerage and consulting, capital-light, with recurring revenue based on commissions and fees, a scale and regulatory moat, and a disciplined complementary M&A strategy. Business quality is high under the three pillars of Quality Investing: strong cash generation, high return on capital, and an attractive reinvestment runway via complementary acquisitions.

The valuation

Valued at the enterprise level by EV/NOPAT on after-tax operating income, insurance-broker archetype (16-22× band). The base case uses an exit multiple of 19× on the result projected 5 years out, with growth decelerating from the current organic level (~5%) toward a terminal ~4.5%. The resulting 5-year value implies Fairly valued with an annual return of +10%.

The margin of safety

It trades close to intrinsic value, far from the required margin of safety. The market price today implies 22× trailing-twelve-month after-tax operating income, above the top of the archetype band (22×), reflecting a TTM result depressed by the Greensill litigation charge (US$425M) and the recognized quality of the business. The margin of safety depends on earnings normalizing and the multiple converging toward the 16-22x range.

What to watch

The central disconfirmer is whether organic growth (currently 4-5%) holds up without the boost from large M&A like McGriff, and whether a "soft" insurance market (falling premium rates) compresses Marsh Risk's commission base more than modeled. Also watch the final resolution of the Greensill litigation and the pace of execution of the Thrive program (targeted annualized savings of US$400 million starting in 2028).
