By Brazil Stock Guide – Banco ABC Brasil (B3: ABCB4) reported net income of R$275.5 million in the fourth quarter of 2025, an increase of 7.3% from the previous quarter and 13.4% from the same period a year earlier. The improvement reflects better margins, though much of the gain was absorbed by higher costs and provisions.
Start with revenues. The bank made more money from its core business in the quarter. Net interest margin (NIM) rose to 4.7% per year, up from 4.4% in 3Q25 and 4.2% in 4Q24. In simple terms, the bank was able to price loans and financial assets better, benefiting from higher spreads and market operations. This pushed gross financial margin up 9.4% quarter on quarter, to R$713.4 million.
However, higher income did not fully convert into profit. Provision expenses jumped 41.1% from the previous quarter, reaching R$126.1 million, as the bank reinforced buffers against potential credit losses. At the same time, personnel and administrative expenses rose 12.1% quarter on quarter, reflecting both inflation and variable compensation linked to performance.
After these costs, the improvement looks more modest. Financial margin after provisions increased only 4.4% q/q, much less than the headline growth in margins. This explains why net income grew, but not as fast as revenues.
Compared with 4Q24, the story is similar. Profit rose 13.4% year on year, helped by stronger client margins and a larger equity base remunerated at CDI. Still, provision expenses were almost 30% higher than a year earlier, and operating costs also increased, keeping earnings growth in check.
On asset quality, the numbers remained comfortable. Loans overdue by more than 90 days fell to 0.5% of the expanded credit portfolio, down 10 basis points from 3Q25. Coverage was high, with provisions equivalent to 501% of non-performing loans, suggesting low realized stress — but also a conservative stance.
Credit growth stayed moderate. The expanded credit portfolio grew 4.7% in the quarter to R$54.7 billion, driven mainly by the middle-market segment, which expanded 8.9% q/q. Exposure to large corporates continued to decline, reinforcing a cautious risk profile.
Profitability improved slightly, not dramatically. Return on average equity (ROAE) reached 16.3% in 4Q25, up from 15.5% in 3Q25 and 15.2% in 4Q24. This shows stabilization at a higher level, but not a clear breakout.
In short, the fourth quarter shows a clear sequence: margins improved first, costs and provisions followed, and net profit landed in the middle. The bank exited 2025 stronger on pricing and asset quality, but still with limited operating leverage.
