MRSH vs NP: 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). NP is the smaller challenger ($4.35B), actually pricier on forward earnings (47.22x): 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.
MRSH vs NP: 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.
| Metric | MRSH | NP | What it tells you |
|---|---|---|---|
| Market cap | $90.52B | $4.35B | Size. The larger name is the incumbent; the smaller has more room to grow and more to prove. |
| Forward P/E | 16.63 | 47.22 | Valuation 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/E | 23.16 | 151.00 | Valuation 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. |
| Price vs 52-week range | 58% of range | 83% of range | Where today's price sits between the 52-week low and high. Near the high is momentum with less margin of safety; near the low is out of favor or a discount, depending on why. |
Reading it: MRSH is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.
Before you buy: how MRSH and NP 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. MRSH and NP 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 MRSH and NP 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.

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.
What does Neptune Insurance Holdings (NP) do?
Neptune Insurance Holdings (NYSE: NP) is a St. Petersburg, Florida insurtech whose main subsidiary, Neptune Flood, is the largest private flood insurance seller in the United States. It operates as a managing general agent, meaning it uses its proprietary AI platform, Triton, to quote, underwrite, and issue residential and commercial flood policies on behalf of a panel of insurance-carrier and reinsurance partners, then earns commissions and fees rather than holding most of the underlying catastrophe risk on its own balance sheet. Triton runs without traditional human underwriters, processes roughly 20,000 quotes on a typical day, and had generated more than 29.7 million lifetime quotes and bound over 1.1 million policies as of mid-2025, with a lifetime written loss ratio around 24.7%. Neptune also offers excess flood coverage and has begun beta-testing parametric and indemnity earthquake products.
MRSH vs NP: 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.
- MRSH drivers: Insurance brokerage scale and pricing cycle; Diversified consulting through Mercer and Oliver Wyman.
- NP drivers: Share shift from the federal NFIP; Technology-driven margin and scale.
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: 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. For NP, the central risks are catastrophe and reinsurance related.
MRSH or NP: 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 MRSH if you believe its drivers more; NP 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 MRSH and NP guides.
MRSH vs NP: the full fundamentals
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.
NP. Figures are approximate and tied to the asOf date; verify live numbers before acting. NP trades at a steep growth multiple, roughly 120x trailing earnings, which reflects investor expectations for continued premium-in-force growth and high agency margins rather than a mature insurer's valuation. The 52-week range (about $14.78 to $33.23) shows how much the stock has moved since its October 2025 IPO, so the numbers matter most as a measure of how much future expansion is already priced in.
Headline figures (approximate, July 2026): MRSH shows revenue (ttm) ~$27.5B, net income (ttm) ~$4.2B, diluted eps (ttm) ~$7.99, market cap ~$86B; NP shows revenue (q1 2026 quarterly) ~$37.8 million, up 29% year over year, adjusted ebitda (q1 2026) ~$21.6 million (~57% margin), up 26%, net income (q1 2026) ~$7.3 million (~$13.4 million adjusted), full-year 2026 guidance ~$195 million revenue, 60% to 61% adjusted EBITDA margin.

FAQ
What is the difference between MRSH and NP?
+
Marsh (ticker MRSH, formerly Marsh & McLennan Companies under MMC) is a global professional services firm built around two segments. Neptune Insurance Holdings (NYSE: NP) is a St. 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 MRSH or NP the better stock?
+

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, MRSH or NP?
+
On forward P/E (as of August 2026), MRSH trades at 16.63x and NP at 47.22x, so MRSH 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 MRSH and NP?
+
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 MRSH vs NP?
+
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. NP: The central risks are catastrophe and reinsurance related. Neptune concentrates in a single, weather-exposed line, so a severe flood season or a string of major storms could spike losses and, more importantly for an agency model, raise the cost or reduce the availability of the reinsurance capacity it depends on. Its economics are also tied to the political fate of the NFIP, whose periodic reauthorization and reform can shift the competitive landscape in either direction. As a recently public, founder-controlled company (CEO Trevor Burgess holds around 82% of voting power), minority shareholders have limited say, and the roughly 120x P/E leaves little room for disappointment if growth or margins slow. Widening loss ratios, higher acquisition costs from new competitors, and regulatory changes across states are additional pressures.
