BRO vs MRSH: Which Is the Better Buy in 2026?

Last updated August 2026

Short answer

MRSH is the larger of the two ($90.52B market cap): the incumbent the market prices for continued execution (16.63x forward earnings, beta 0.60). BRO is the smaller challenger ($23.56B), priced similarly on forward earnings (14.61x): more room to run, but more to prove. The real question is which set of drivers you believe, and whether owning one (or both) leaves you over-concentrated.

BRO vs MRSH: the tie-breaker metrics

Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

MetricBROMRSHWhat it tells you
Market cap$23.56B$90.52BSize. The larger name is the incumbent; the smaller has more room to grow and more to prove.
Forward P/E14.6116.63Valuation on next year's expected earnings, the same yardstick for both. Lower is cheaper for that growth; higher means the market is paying up.
Trailing P/E22.4923.16Valuation on the last 12 months. A big drop from trailing to forward means the market expects earnings to jump, so more growth is already in the price.

Before you buy: how BRO and MRSH affect your concentration

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. BRO and MRSH share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined BRO and MRSH exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker. Walnut is not an investment adviser.

What does Brown & Brown (BRO) do?

Brown & Brown is a Daytona Beach, Florida based insurance intermediary that connects businesses and individuals with insurance carriers, collecting commissions and fees instead of taking underwriting risk on its own balance sheet. It operates through two reportable segments after a 2025 reorganization, Retail and Specialty Distribution, spanning property and casualty, employee benefits, programs, and wholesale brokerage. The business is fee-based and capital-light, which historically produced high margins, strong free cash flow, and decades of dividend increases, and management has grown for years by acquiring smaller agencies and folding them into its decentralized model.

What does Marsh (MRSH) do?

Marsh (ticker MRSH, formerly Marsh & McLennan Companies under MMC) is a global professional services firm built around two segments. Risk and Insurance Services houses Marsh, the world's largest insurance brokerage, and Guy Carpenter, a leading reinsurance broker. The Consulting segment houses Mercer, a large health, wealth, and career consultancy, and Oliver Wyman, a management consulting brand. Together these businesses employ roughly 90,000 people and generate the bulk of revenue from recurring commissions and advisory fees tied to commercial insurance placement, reinsurance, retirement, and workforce advisory work.

BRO vs MRSH: how do they differ?

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

  • BRO drivers: Acquisition-led compounding; Fee-based, capital-light economics.
  • MRSH drivers: Insurance brokerage scale and pricing cycle; Diversified consulting through Mercer and Oliver Wyman.

Which fits which kind of investor

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: The dominant near-term risk is a softening insurance-rate environment: organic growth slowed toward the mid single digits (around 3.6% in a recent quarter versus roughly 10% a year earlier) as premium rates flatten or fall across property, casualty, cyber, and executive lines, which pressures commission-based revenue. For MRSH, as an insurance broker, revenue is tied to the commercial insurance pricing cycle, and a prolonged soft market with falling premium rates would slow commission growth.

BRO or MRSH: which should you pick?

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick BRO if you believe its drivers more; MRSH if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the BRO and MRSH guides.

BRO vs MRSH: the full fundamentals

BRO. As of mid-July 2026 BRO traded near the high $60s with a market cap around $23 billion and a trailing P/E in the low 20s, a premium typical of high-quality insurance brokers. The 2025 revenue jump to over $5.9 billion was driven heavily by the Accession acquisition rather than organic growth, which had slowed to the mid single digits. The forward multiple sits below the trailing multiple, reflecting expected earnings accretion from a full year of Accession.

MRSH. Marsh generated roughly $27 billion in trailing revenue with high-single-digit organic growth and expanding adjusted margins. It trades around a low-20s price to earnings multiple, a premium that reflects its recurring fee revenue and steady compounding rather than rapid growth. The next quarterly report is expected in late July 2026.

Headline figures (approximate, July 2026): BRO shows revenue (ttm) ~$7 billion, 2025 total revenue ~$5.9 billion (+~23% YoY), market cap ~$23 billion, trailing p/e ~21x; MRSH shows revenue (ttm) ~$27.5B, net income (ttm) ~$4.2B, diluted eps (ttm) ~$7.99, market cap ~$86B.

The bottom line: BRO vs MRSH

BRO and MRSH are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined BRO and MRSH exposure against your real portfolio. It is not an investment adviser.

FAQ

What is the difference between BRO and MRSH?

+

Brown & Brown is a Daytona Beach, Florida based insurance intermediary that connects businesses and individuals with insurance carriers, collecting commissions and fees instead of taking underwriting risk on its own balance sheet. Marsh (ticker MRSH, formerly Marsh & McLennan Companies under MMC) is a global professional services firm built around two segments. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.

Is BRO or MRSH the better stock?

+

Neither is universally better. MRSH is the larger incumbent; BRO is the smaller challenger and looks cheaper on forward earnings. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.

Which is cheaper, BRO or MRSH?

+

On forward P/E (as of August 2026), BRO trades at 14.61x and MRSH at 16.63x, so BRO is the cheaper of the two on next year's expected earnings. A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.

Should you own both BRO and MRSH?

+

Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.

What are the risks of BRO vs MRSH?

+

BRO: The dominant near-term risk is a softening insurance-rate environment: organic growth slowed toward the mid single digits (around 3.6% in a recent quarter versus roughly 10% a year earlier) as premium rates flatten or fall across property, casualty, cyber, and executive lines, which pressures commission-based revenue. Integration risk from the large debt-funded Accession deal is significant, and the added leverage reduces financial flexibility if results disappoint. The stock trades at a premium valuation, so any further deceleration in organic growth or margin can drive sharp multiple compression, as the market reaction to recent results showed. Falling interest rates would reduce income on fiduciary balances, and a downturn in carrier profitability could shrink contingent commissions. Longer term, consolidation among larger rivals and questions about AI disrupting distribution add competitive uncertainty. MRSH: As an insurance broker, revenue is tied to the commercial insurance pricing cycle, and a prolonged soft market with falling premium rates would slow commission growth. The consulting businesses are more cyclical and can weaken when corporate clients cut discretionary project and benefits spending. The stock trades at a premium valuation (a low-20s price to earnings multiple), so disappointing organic growth or margins could compress the multiple. Large acquisitions carry integration and goodwill risk, and the firm faces professional liability and regulatory exposure across many jurisdictions. Currency swings also affect reported results given the global footprint.
