Santander's €12.4bn is a Poland story; the €11.2bn is the real one

When a bank reports a record, which of its numbers should you believe? Santander's nine-month results are a textbook case: the big figure is real, but it isn't the one that should anchor your view of the bank.

Santander says its attributable profit for the first nine months of 2026 reached €12,405 million, up 20%. Underneath sits a different number: a record underlying profit of €11,176 million, up 16%, which the bank credits to strong customer activity and its ONE Transformation efficiency program. It also says it added 17 million customers in a year.

The headline profit is real, but Poland is doing the heavy lifting

The gap between the two numbers is the story. According to The Corner, the reported figure includes a €1.9 billion net capital gain from completing the sale of Santander Bank Polska in January, partly offset by €666 million in charges, including integration costs tied to TSB and Webster. Do the arithmetic and it roughly reconciles: about €1.9bn of gain minus €666m of charges is a bit over €1.2bn, which is the distance between €11.2bn and €12.4bn.

A capital gain is a receipt, not a business line. Santander can't sell Poland again next year. Its own accounting treats it that way: in the underlying income statement, the Polish business and the resulting gain are parked in a single "non-recurring items" line and excluded from underlying profit. So the 20% includes a large one-time credit that the 16% leaves out.

A sale gain happens once; the 16% is the number that has to repeat

The ordinary 16% is the number that deserves the applause, and it deserves it fairly. A record underlying profit growing at that pace is not trivial. We would simply argue it's a different kind of achievement than the headline suggests, and that the 4-point gap between 16% and 20% is precisely the part nobody should extrapolate.

There is a second reason to prefer the underlying figure. The documentation we have doesn't break out how much of the improvement comes from customer growth, cost cuts or anything else, so we won't pretend to know. But in our view profit earned through efficiency and a growing client base deserves more weight than profit that comes from a one-off disposal.

Strong profits don't guarantee a happy market

We can't say how investors will digest Santander's numbers, and one session proves little anyway. But there is a useful reminder from another large bank: HSBC's earnings jumped 32% in the third quarter, yet its shares fell 5%, according to Ámbito. In our view that suggests investors already expect strong bank earnings and are asking what comes next, not applauding what has already been booked.

This is the underrated point. A record is backward-looking by definition. Markets price the future, and Santander has reiterated its 2026 targets, according to RTTNews' headline. Whether those targets hold up is the real test, and it will show up in ordinary profit, not in a divestment gain.

Read the 16%, treat the 20% as a one-off

This is not investment advice, and we don't know your goals or your tax situation, which also differ by country. As a way of reading results, though, a few habits would serve most readers well:

• Start with the underlying figure, then check what sits between it and the reported one.
• Treat sale gains and restructuring charges as one-offs in both directions: they flatter or punish a single period.
• Watch how a stock reacts over several sessions, not one morning. A drop on good news often means expectations were higher than the result.

Our verdict: Santander had a very good nine months, and a record €11,176 million of ordinary profit says so without any help. But the €12.4bn headline is dressed up by Poland, and anyone using it as a run rate is fooling themselves. Judge the bank by the 16%, not the 20%.
