◆ What the Market Isn't Pricing In

PKO Bank Polski (PKO) — the variant view

At 2,3 times book and 13,6 times earnings, the market is paying a premium for a bank whose statutory tax rate falls seven points over the next two years.

At the end of 2022 PKO was worth 37 863 million złoty. It is now worth about 147 900 million1 — very nearly four times, in under four years.

Price to book, year-end1,49x20211,06x20221,39x20231,43x20241,82x20252,26x2026From 1,06x at the 2022 trough to 2,26x - the re-rating happened before the tax cut is legislated
At 2,3 times book the market is already paying for a bank whose statutory tax rate falls seven points by 2028. The relief is priced; the margin decline may not be.

The re-rating is the whole story and it is the exact opposite of Allegro's. The multiple went from 11,4 times earnings in 2022 to 8,0 in 2024 and 13,6 now2, while net profit went 3 312 million to 10 682 million3 and return on equity from 9,6% to 19,5%4. The market was pricing a bank buried in Swiss franc litigation and credit holidays; it is now pricing one earning nearly 20% on equity.

The bull case is that the earnings are real and the overhang is closing. Cost of credit risk is 0,30% and has improved four years running5; impaired exposures have fallen every year since 20216; the Swiss franc charge fell 534 million in 2025 and the first half of 2026 added only 685 million7; the capital ratio supports a 75% payout at a 5,0% yield8; and the 2027 return-on-equity target of above 18% was already beaten in 2025.

The bear case is that none of the three largest variables belongs to the bank. The interest margin is set by the National Bank of Poland and has already fallen 44 basis points9. The tax rate is set by the government, which raised it from 19% to 30%10. The Swiss franc liability is set by the courts. PKO's management controls the cost base, the underwriting and the customer experience — and those are the parts already running close to their best.

What neither side prices properly is the tax schedule. The rate is legislated to fall to 26% in 2027 and 23% in 202811, which on a pre-tax profit above 16 billion złoty is worth more than any commercial initiative the bank could undertake. It requires only that the government does what the current law already says — and the same government proposed a further increase in bank taxation in July 2026. That is a large, binary, entirely political swing factor sitting inside a stock usually analysed on net interest margin.

There is a quieter one in the income mix. Fees are 17,3% of income and grew 2,4% against interest income's 9,3%12, so the business became more rate-dependent in the year before rates turned. The Allegro and Automarket ecosystems are the answer, and they are small.

There is a third thing the market may be reading too simply, and it is the book value. PKO trades at about 2,3 times book13 on equity of 58 503 million złoty14, which is a full price for a European bank. But that equity absorbed 4 365 million złoty of Swiss franc charges in 2025 alone15 and still grew from 52 370 million — so the book being multiplied is one that has been repeatedly written down and rebuilt, rather than one carried at an untested value.

Watch two numbers and ignore the noise: the effective tax rate, and net interest income rather than the margin. The first decides how much of the return shareholders keep. The second decides whether 13% volume growth is still covering a falling spread.
