Shares of Capital One Financial (NYSE: COF) fell more than 6% intra-day on Friday after the lender announced plans to acquire fintech firm Brex Inc. and reported fourth-quarter earnings that missed expectations.

Capital One said it entered into a definitive agreement to acquire Brex, a corporate credit card specialist, for $5.15 billion, with the transaction structured as approximately 50% cash and 50% stock. The acquisition was viewed as a strategic effort to diversify Capital One's revenue base beyond consumer lending and potentially provide greater resilience during future economic downturns.

Capital One's provision for credit losses increased by $1.4 billion to $4.1 billion, including $3.8 billion in net charge-offs and a $302 million build in loan reserves. Period-end loans held for investment rose 2% to $453.6 billion, with credit card loans increasing 3% to $279.6 billion. Total deposits grew 1% to $475.8 billion.

Net interest margin declined by 10 basis points from the prior quarter to 8.26%. The company reported a Common Equity Tier 1 capital ratio of 14.3% under the Basel III standardized framework as of December 31, 2025.

For full-year 2025, Capital One posted a 37% increase in total net revenue to $53.4 billion, while total non-interest expenses rose 42% to $30.5 billion.
