This 6-K filing provides extensive regulatory disclosures on Itau Unibanco's risk and capital management as of December 31, 2025. Key capital ratios, including Common Equity Tier 1, Tier 1, and Total Capital, experienced a notable decline from the previous quarter, primarily driven by increased risk-weighted assets and shareholder distributions (dividends and share buybacks). Despite this, the bank maintains a substantial capital surplus well above regulatory minimums. The report also disclosed a past model miscalibration in its agribusiness probability of default model, which was identified and subsequently addressed with a new model. Liquidity ratios remain robust, and problem assets decreased, indicating a stable overall risk profile. Investors should monitor future capital ratio trends in light of continued RWA growth and capital allocation strategies.
