Banco Santander’s third-quarter results show why an earnings headline needs its accounting basis. Underlying profit rose 19% year on year to €3.848 billion, but reported attributable profit fell 2% to €3.432 billion. The bank disclosed the figures on 28 October 2026 in its official results release filed with Spain’s CNMV.
The practical distinction is €416 million of third-quarter non-recurring charges. Subtracting those charges from underlying profit gives the reported figure: €3.848 billion minus €0.416 billion equals €3.432 billion. Neither number should be described as the other.

What underlying profit leaves out
Underlying profit is an alternative performance measure: it removes specified items to present the bank’s view of operating performance. It supplements, rather than replaces, reported results. A higher underlying figure does not erase a charge borne in the reported accounts.
The nine-month comparison points in the opposite direction from the quarter. Reported attributable profit exceeded underlying profit by €1.229 billion. That net benefit reflected a €1.895 billion capital gain from the Poland disposal, partly offset by €666 million of charges, including acquisition-related integration costs and intangible-asset impairments. These are nine-month amounts, not additional third-quarter gains.
How to read the growth rates
The percentages above use current euros. They must not be mixed with the release’s separate constant-euro comparisons, which remove specified currency effects. Likewise, comparing a three-month result with a nine-month total would mix reporting periods.
For readers comparing banks, the next useful step is to place the reported and underlying measures side by side, identify the excluded items, and keep the period and currency basis consistent. CapKet’s six-field earnings comparison worksheet provides a reusable check.
