Approach 1: Banco Santander Excess Returns Analysis

The Excess Returns model looks at how much value Banco Santander creates over and above the minimum return that shareholders require. Instead of focusing on cash flows, it starts from the bank’s equity base and asks whether its returns on that equity are high enough, and durable enough, to justify a premium over book value.

For Santander, the model assumes a Book Value of €6.82 per share and a Stable EPS of €1.03 per share, based on weighted future Return on Equity estimates from 14 analysts. With an Average Return on Equity of 13.21% compared with a Cost of Equity of €0.73 per share, the bank is expected to generate an Excess Return of €0.30 per share on a Stable Book Value rising to €7.79 per share, using book value forecasts from 9 analysts.

When these excess returns are projected forward and discounted back, the model arrives at an intrinsic value of about €11.99 per share, suggesting the stock is trading at a 16.6% discount to its current price. In other words, the market is not fully pricing in Santander’s ability to earn returns above its cost of equity.

Result: UNDERVALUED

Our Excess Returns analysis suggests Banco Santander is undervalued by 16.6%. Track this in your watchlist or portfolio, or discover 916 more undervalued stocks based on cash flows.

Approach 2: Banco Santander Price vs Earnings

For a consistently profitable bank like Banco Santander, the price to earnings, or PE, ratio is a practical way to gauge what investors are willing to pay for each euro of earnings today. In general, stronger and more reliable earnings growth, combined with lower perceived risk, justify a higher PE multiple, while slower growth or higher risk usually warrant a lower one.

Santander currently trades on a PE of 11.48x, which is slightly above the global Banks industry average of about 10.84x and very close to its peer group average of 11.43x. Simply Wall St also estimates a Fair Ratio for Santander of 12.32x, which reflects what investors might reasonably pay given its earnings growth outlook, profitability, size, industry positioning and risk profile.

This Fair Ratio is more informative than a simple comparison to peers or the sector, because it adjusts for Santander specific characteristics, rather than assuming all banks deserve the same multiple. Comparing the Fair Ratio of 12.32x with the current PE of 11.48x suggests the market is applying a modest discount to what would be considered reasonable, which indicates that the shares still look slightly undervalued on earnings.

Result: UNDERVALUED

Upgrade Your Decision Making: Choose your Banco Santander Narrative

Earlier we mentioned that there is an even better way to understand valuation, so let us introduce you to Narratives, which are simply your story about a company expressed as numbers like your fair value, and your expectations for future revenue, earnings and margins, all linked together. A Narrative connects what you believe about Santander’s strategy, risks and opportunities to a concrete financial forecast and then to an implied fair value, so you can directly compare that fair value with today’s share price to decide whether it looks like a buy, hold or sell. On Simply Wall St, millions of investors build and share these Narratives on the Community page, and they update dynamically as new information, such as earnings or major news, comes in. For example, one Santander Narrative might lean bullish, assuming revenue growth closer to the top end of analyst expectations and a fair value near €9.5 per share, while a more cautious Narrative might assume slower growth, lower margins and a fair value closer to €5.8, giving you a clear, numbers based view of how different perspectives translate into different investment decisions.
