Profitability
Q2 annualizedCapital & Liquidity
Balance Sheet
Income Statement
Operating & Funding
Rows tagged YTD are fiscal year to date through June 30, 2026, as filed. Net income is tagged Q2 because it is that quarter's own figure, not a running total, so it cannot be compared with a YTD row. ROA, ROE and net interest margin are the quarter's own income, annualized. The UBPR and FDIC annualize the year to date instead, so after the first quarter their figures differ from ours; where the UBPR has this quarter, its value is shown beside each as YTD. The UBPR's YTD ROA divides by the average of the quarterly average assets the bank reports on Schedule RC-K, while FDIC BankFind divides by the average of quarter-end total assets, so FDIC's ROA can differ from the YTD figure by a few hundredths of a point.
Quarterly trends
Last 12 quarters from this bank's own FFIEC call reports. Dollar figures are the quarter's own amount: the income statement is filed year to date, so those lines are shown net of the preceding quarter.
Balances at each quarter end. The gap between the two lines is equity capital.
Balances at each quarter end. Loans rising toward deposits is the loan-to-deposit ratio tightening.
Balances at each quarter end. Each line is its own balance, not stacked on the other.
Each bar is that quarter alone. The gap between the two is net interest income.
What the balance sheet earned on spread that quarter, before fees and operating costs.
Fees, trading and other income against salaries, premises and the rest of the cost base.
What the bank charged to earnings that quarter to build its allowance for expected losses.
Net income for the quarter alone. The Call Report reports it year to date; this series converts it to the single quarter, so each bar covers three months.
CET1 is common equity tier 1 as a share of risk-weighted assets; the leverage ratio is tier 1 capital as a share of average total assets. A bank that files the community bank leverage ratio reports no CET1 ratio, so only its leverage line appears.
