About this comparison
All metrics are sourced from FFIEC call report filings, the public regulatory financial reports every FDIC-insured US bank files quarterly. Both banks are reported as of June 30, 2026. The "winner" highlight is determined by the supervisory direction convention: higher is better for capital and profitability metrics; lower is better for risk metrics like Texas Ratio and uninsured-deposit ratio. Size and identity rows (assets, deposits, loans, equity, branches, employees) are shown for context and are not scored, and two values that match at the precision shown count as a tie.
