Capital One Financial on Tuesday evening reported second-quarter results that topped expectations on both the top and bottom lines. While the company's business model transformation is testing our patience, the payoff could ultimately be worth the wait. Revenue in the second quarter ended June 30 increased 27% year over year to $15.85 billion, beating the $15.77 billion consensus estimate of analysts surveyed by LSEG.

Adjusted earnings per share (EPS) increased 6% year over year to $5.81, beating the $4.75 estimate, LSEG data showed. COF YTD mountain Capital One YTD Capital One shares were relatively unchanged in after-hours trading at $206. For 2026, the stock is down about 15%.

Bottom line The top-line beat was driven by strength in non-interest income, which continued its string of positive results. Non-interest income revenue increased 39% year over year and about 13% quarter over quarter. The sequential increase was driven by a 15% increase in net discount and interchange fees, which totaled $2.26 billion.

Because Capital One now owns the Discover payment network, it can capture more of the economics from card transactions rather than relying solely on third-party networks. Its continued growth is a positive indicator for the Discover integration story. Net interest income (NII) of $12.37 billion came in slightly below Street estimates, despite growing about 24% year over year.

Similarly, net Interest margin improved year over year, but not at the magnitude the Street forecasted. Offsetting some of the top-line growth was another big surge in non-interest expenses. This figure increased 29% year over year to $9 billion, driven by a 23% increase in marketing expenses, which totaled $1.66 billion.

That's actually below the FactSet estimate of $1.7 billion. Capital One likes to lean into marketing and media to drive new account originations in its domestic credit card and checking account business. Higher operating expenses were another factor, and the increase may be due in part to the inclusion of the acquisition of Brex into the financials.

Brex is a fintech company that provides corporate credit cards, expense management software, and cash management tools that help businesses manage spending and finances. Capital One paid more than $5 billion to acquire this business in April. As for buybacks, Capital One repurchased 14 million shares for $2.7 billion in the second quarter.

That's a small step up from the $2.5 billion repurchased in the first quarter. Capital One still has about $9 billion remaining under its share repurchase authorization, so we expect plenty of repurchases through the rest of the year. Integration timelines The biggest question on our minds is when Capital One will begin to see more tangible benefits from its deals.

It was something we talked about in our earnings preview story . That has been one of the key storylines holding the stock back in 2026 after a strong finish to 2025. Although the company is working hard to drive the revenue and expense synergies from its two integrations, these gains are taking some time.

The reported results include the full run-rate debit revenue synergy tied to the Discover deal, which we can see with the net discount and interchange fees above.
