At September 30, 2023, total assets were $5.25bn, loans were $4.10bn gross ($4.06bn net), deposits were $3.90bn, and shareholders’ equity was $483.2m. Total assets increased $378m, loans $188m, and deposits $188m from year-end 2022. Cash and cash equivalents rose to $266.0m from $96.8m.
- Cash flow, nine months: operating activities provided $73.9m, investing activities used $197.1m, and financing activities provided $292.4m. Cash increased $169.2m, compared with a $691.1m decrease in the prior-year period.
- Credit: allowance for credit losses was $48.0m, or 1.17% of loans, versus $42.2m at year-end. Nonperforming loans were $5.9m (0.14% of loans), down from $7.7m; year-to-date net charge-offs were approximately $0.1m.
- Borrowings and liquidity: FHLB advances totaled $457.9m, up $149.6m from year-end; repurchase agreements were $164.1m, down $30.3m. Subordinated debentures and notes totaled $138.4m. The bank reported $424m of remaining FHLB borrowing availability based on collateral and $70m of correspondent-bank lines.
- Capital: the bank’s total risk-based capital ratio was 13.8%, above the 10.0% well-capitalized threshold; common equity Tier 1 was 12.8%. The bank reported $185m of capital in excess of the total-capital amount associated with that threshold.
Material changes versus comparable periods
- Q3 net income rose about 30% year over year; nine-month net income rose about 58%. Management attributed the improvement mainly to stronger net interest income from higher asset yields and loan growth.
- Net interest margin expanded to 3.98% in Q3 and 4.10% year to date. Higher interest rates also sharply increased funding costs: Q3 interest expense was $22.2m versus $5.8m, and nine-month expense was $52.7m versus $16.0m.
- Gross loans grew 4.8% from year-end. Residential mortgage loans grew about $99.9m, while commercial loans increased $87.0m; commercial and industrial loans declined $18.9m.
- Deposit balances shifted toward interest-bearing products. Noninterest-bearing deposits fell $295m, while money-market deposits rose about $200m and time deposits increased. Total deposits grew, but wholesale funding—out-of-area deposits and FHLB advances—rose to $569m, about 13% of deposits and borrowings, from $308m, about 7%.
- The available-for-sale securities portfolio had a $93.2m net unrealized loss at September 30, versus $82.7m at year-end, largely attributed to higher market interest rates. The nine-month after-tax decline in securities value reduced equity by $8.2m.
- Nine-month noninterest income edged down $0.5m, as lower mortgage banking income and service charges offset growth in card, swap, and payroll fees. Noninterest expense increased $5.9m, including higher compensation, FDIC assessments, unfunded-commitment reserves, and swap-collateral costs.
Outlook, management commentary, risks, and unusual items
- Management described the commercial loan pipeline as strong. It cited $379m of unfunded commitments on commercial construction and development loans already in construction, expected to draw over 12–18 months, and approximately $288m of new lending commitments expected to be accepted and funded over that period. These are management expectations, not earnings guidance.
- Management expects future securities purchases to generally be municipal bonds and the securities portfolio to remain about 12% of total assets. No formal earnings or full-year financial guidance is provided in the supplied filing text.
- Credit-loss estimates reflect loan growth, residential mortgage prepayment assumptions, and local economic considerations, including potential effects of the United Auto Workers strike involving Detroit automakers. Management cited strong overall loan quality but cautioned that deteriorating loan quality or economic conditions could require higher reserves.
- Interest-rate exposure is material: management’s model estimated next-12-month net interest income changes from -12.4% under a 300-basis-point rate decline to +10.4% under a 300-basis-point increase. The filing cautions that model assumptions are uncertain and actual results may differ.
- Liquidity risks include deposit migration, rate competition, potentially volatile sweep balances, and reliance on wholesale funding. Sweep accounts are secured borrowings, not deposits, and are not federally insured. Management reported monitoring liquidity and maintaining contingency funding plans.
- Other identified risks include commercial real estate values, recession and inflation, customer repayment capacity, competition, regulation, cybersecurity, technology, litigation, and operational and reputational risks. The company reported no material change in risk factors from its 2022 Form 10-K.
- Unusual items included a $0.4m gain on sale of other real estate owned and a $0.4m write-down of a former branch facility during the year. The company reported no material current legal proceedings, effective disclosure controls, and no material change in internal control over financial reporting.
Important facts for investors to verify
- Whether deposit growth and funding costs remain favorable as noninterest-bearing balances decline and time deposits and wholesale funding increase.
- Whether loan growth—particularly commercial real estate, construction, and residential mortgage lending—continues without deterioration in delinquencies, criticized loans, or loss reserves.
- How much of the $379m construction commitments and $288m new lending commitments is ultimately drawn, and the related liquidity and capital effects.
- Whether the $93.2m unrealized securities loss changes further, and how interest rates affect reported equity, liquidity, and net interest income.
- Whether the reported $424m of collateral-based FHLB availability and other funding sources remain accessible under stressed conditions.
- Whether actual margins and earnings track management’s rate-sensitivity scenarios; the filing states that modeled results rely on assumptions and are not forecasts.
