One web search result (24/7 Wall St.) explicitly confirms revenue of $15.23 billion for Q1. While another source mentions net interest income was up 52%, it does not explicitly confirm the total revenue figure of $15.23 billion as a standalone fact from a second independent organization.

The 24/7 Wall St. source mentions revenue of $15.23 billion against 'roughly $15.37 billion expected', which is very close to the $15.36 billion claim, but only one source provides this specific analyst estimate context.

The 24/7 Wall St. source explicitly confirms adjusted EPS of $4.42 versus a $4.55 to $4.57 estimate. No other independent source corroborates these specific figures.

The provided evidence discusses interchange fees in general or other bank metrics, but does not provide the specific figure of $1.964 billion for Capital One's net discount and interchange fees.

One source (Capital One investor relations material) mentions non-interest expense was $8.5 billion, which is approximately $8.46 billion, but the specific analyst expectation of $8.3 billion is not corroborated by a second independent source.

The 24/7 Wall St. source explicitly mentions GAAP EPS was weighed by $892 million in combined Discover amortization and integration costs, which aligns closely with the $893 million claim. No other source provides this specific figure.

The search results provide general information about Capital One or general definitions of ratio analysis, but do not contain the specific efficiency ratio percentages (49.71%, 53.73%, 55.94%) mentioned in the claim.
