Approach 1: Marsh & McLennan Companies Excess Returns Analysis

The Excess Returns model asks whether Marsh & McLennan Companies is generating returns on shareholders equity that are comfortably above its cost of capital, and what that gap is worth over time. It starts from the company book value per share and then estimates the value created by earning more than investors required return.

For Marsh & McLennan, the starting Book Value is $30.92 per share, with a Stable Book Value of $36.45 per share, based on weighted future estimates from four analysts. Against this equity base, the business is expected to deliver Stable EPS of $10.87 per share, implying an Average Return on Equity of 29.82%. With a Cost of Equity of only $2.54 per share, the model estimates Excess Return of $8.33 per share, meaning most of the forecast earnings are economic profit rather than just covering the capital charge.

Aggregating these excess returns, the model arrives at an intrinsic value of roughly $261.90 per share, implying the stock is about 30.0% undervalued relative to its current trading price.

Result: UNDERVALUED

Our Excess Returns analysis suggests Marsh & McLennan Companies is undervalued by 30.0%. Track this in your watchlist or portfolio, or discover 933 more undervalued stocks based on cash flows.

Approach 2: Marsh & McLennan Companies Price vs Earnings

For established, consistently profitable businesses like Marsh & McLennan Companies, the price to earnings (PE) ratio is a useful shorthand for how much investors are willing to pay for each dollar of current earnings. It links today’s price directly to the company’s profit engine, which is ultimately what funds dividends, buybacks and reinvestment.

What counts as a normal or fair PE depends on how fast earnings are expected to grow and how risky those earnings are. Higher growth and more predictable cash flows usually justify a higher multiple, while slower or more volatile growth tends to pull the PE down. Marsh & McLennan currently trades on a PE of 21.77x, above the Insurance industry average of about 13.06x but below the peer group average of roughly 27.09x. This suggests the market already prices in some quality and growth, but not to the same extent as its closest comparables.

Simply Wall St’s fair ratio framework goes a step further. Instead of just comparing Marsh & McLennan with broad industry or peer averages, it estimates what a tailored PE should be once factors like the company-specific earnings growth outlook, profitability, risk profile, industry and market cap are all taken into account. For Marsh & McLennan, this fair ratio is 14.85x, well below the current 21.77x, implying the shares are pricing in more optimism than this fundamentals-based model supports.

Result: OVERVALUED

Upgrade Your Decision Making: Choose your Marsh & McLennan Companies Narrative

Earlier we mentioned that there is an even better way to understand valuation, so let us introduce you to Narratives, a simple framework on Simply Wall St’s Community page where you connect your view of a company’s story to your own forecast for its future revenue, earnings and margins, and then to a fair value you can compare with today’s share price. Instead of just accepting a PE ratio or analyst target, you can pick or build a Narrative that reflects how you think Marsh and McLennan will navigate rising risk complexity, regulation and digital disruption, and the platform turns that story into numbers that show whether the stock looks expensive or attractive. Narratives are dynamic, automatically updating when new earnings, news or guidance come in, so your fair value view evolves as the facts change. For example, one investor might back a more bullish Narrative that sees Marsh and McLennan compounding steadily and justifying a fair value closer to $258 per share. A more cautious investor could choose a Narrative aligned with a $197 view, and each can decide whether to buy, hold or sell based on how their chosen fair value compares with the current price.
