Capital One Financial Corp

Capital One closed Q4 2025 with a mixed result that underscored both the transformative scale of its Discover integration and the near-term costs that come with it, as adjusted EPS of $3.86 missed the $4.14 consensus estimate by 6.76% even as revenue of $15.58 billion exceeded expectations and grew 12.8% year over year. The primary driver behind the earnings shortfall was a surge in non-interest expense, which climbed 53% year over year to $9.34 billion, reflecting Discover integration costs, a $352 million integration expense charge, and a sharp 38% sequential jump in marketing spend. The acquisition, completed in May 2025, reshaped Capital One's footprint dramatically, with period-end credit card loans expanding 72% year over year to $279.57 billion and net interest margin improving 123 basis points from the prior-year period to 8.26%. Looking ahead, the company's announced agreement to acquire Brex Inc. for $5.15 billion signals that management is far from finished building, with analysts broadly maintaining a constructive view on the stock's long-term upside as integration synergies take hold.
