Approach 1: American Express Excess Returns Analysis

The Excess Returns model looks at how much profit American Express can generate above the return that equity investors typically require, then capitalizes those surplus profits into an estimated intrinsic value per share. Instead of focusing on cash flows, it evaluates how effectively the company is using shareholder capital.

For American Express, the model starts with a Book Value of $49.85 per share and a Stable EPS estimate of $20.82 per share, based on weighted future Return on Equity estimates from 13 analysts. The Average Return on Equity used in the model is 35.64%, which is compared with a Cost of Equity of $4.79 per share. The gap between these figures produces an Excess Return of $16.03 per share.

The model also uses a Stable Book Value of $58.42 per share, based on weighted future Book Value estimates from 9 analysts. Combining these assumptions, the Excess Returns model arrives at an intrinsic value of about $402.58 per share, which is 14.9% above the recent share price of $342.56. On this measure, American Express stock screens as undervalued.

Result: UNDERVALUED

Approach 2: American Express Price vs Earnings

For a profitable company like American Express, the P/E ratio is a straightforward way to relate what you are paying for each dollar of current earnings. It connects the share price directly to earnings power, which many investors see as a core driver of long term value.

What counts as a reasonable P/E depends on what the market expects for future growth and how risky those earnings appear. Higher expected growth or lower perceived risk can support a higher multiple, while slower growth or higher risk often point to a lower one.

American Express currently trades at a P/E of 21.08x. This is higher than the Consumer Finance industry average P/E of 8.50x and above a peer group average of 19.51x. Simply Wall St also calculates a Fair Ratio of 19.53x for American Express, based on factors such as its earnings profile, industry, profit margins, market value and risk characteristics. This Fair Ratio aims to be more tailored than simple peer or industry comparisons because it adjusts for company specific traits rather than assuming all companies deserve the same multiple.

Comparing the Fair Ratio of 19.53x with the actual P/E of 21.08x suggests American Express stock screens as overvalued on this metric.

Result: OVERVALUED

Upgrade Your Decision Making: Choose your American Express Narrative

Earlier it was mentioned that there is an even better way to think about valuation. Here is Narratives, a simple way for you to attach your story about American Express to the numbers by combining your view on its future revenue, earnings, margins and fair value into a single, shareable forecast. This links the company’s business story to a cash flow outlook, then to a Fair Value that you can compare with today’s price to decide whether you see the stock as expensive or cheap. All of this is available within the Narratives tool on Simply Wall St’s Community page, where Narratives update automatically when fresh data, news or earnings arrive. For example, one investor might build a Narrative that lines up with a higher Fair Value near US$440.45, while another might anchor on a more cautious Fair Value around US$285, and both can clearly see how their assumptions differ and what that means for their view of American Express at its current share price.

For American Express, however, we will make it really easy for you with previews of two leading American Express Narratives:

Both are built from the same underlying data but reach different conclusions. This is exactly what you want when stress testing your own view on the stock.

Revenue growth assumption: 11.43% per year

• Leans on American Express focusing on premium cardmembers, younger affluent customers, and product refreshes to support card fee growth, spending and retention.
• Builds in analyst expectations for double digit revenue growth, resilient credit quality and ongoing buybacks to support earnings and per share outcomes.
• Flags risks around rising competition in premium cards, changing payment habits, higher engagement costs and the potential impact of lower margin assumptions on future returns.

Narrative fair value: US$299.60 per share

Implied overvaluation vs last close: about 14.3% above this fair value

Revenue growth assumption: 6.81% per year

• Highlights that American Express has a wide moat, solid margins and EPS growth, but questions how value accretive those returns are when recent return on invested capital is close to the cost of capital.
• Uses several valuation methods, including DCF, EPS growth, dividend models and historical multiples, which together point to a lower blended fair value than the current share price.
• Emphasizes that the current P/E, P/B and dividend yield sit above or below historical averages in ways that suggest the stock could be priced ahead of the weighted fair value estimate.
