OAK VALLEY BANCORP REPORTS 3rd QUARTER RESULTS

OAKDALE, CA – Oak Valley Bancorp (NASDAQ: OVLY) (the “Company”), the bank holding company for Oak Valley Community Bank and their Eastern Sierra Community Bank division, recently reported unaudited consolidated financial results. For the three months ended September 30, 2025, consolidated net income was $6,693,000, or $0.81 per diluted share (EPS), as compared to $5,588,000, or $0.67 EPS, for the prior quarter and $7,324,000, or $0.89 EPS, for the same period a year ago. Consolidated net income for the nine months ended September 30, 2025 was $17,578,000, or $2.12 EPS, compared to $18,940,000 or $2.30 EPS for the same period of 2024.

The increase in third quarter net income compared to the prior quarter was due to earning asset growth, an increase in the yield of the loan portfolio, and the corresponding increase to net interest income. The QTD and YTD decreases compared to the same periods of 2024 are primarily due to a reversal of allowance for credit losses of $1,620,000 recorded in the third quarter of 2024 that was related to loan recoveries, and an increase in general operating expenses.

Net interest income for the three months ended September 30, 2025 was $19,197,000, compared to $18,154,000 in the prior quarter, and $17,655,000 in the same period a year ago. The increase in net interest income over the prior periods is attributed to average earning asset growth, rising loan yields, and a slight decrease in average cost of funds. Net interest margin for the three months ended September 30, 2025 was 4.16% (1), compared to 4.11% (1) for the prior quarter and 4.04% (1) for the same period last year.

Non-interest income was $1,973,000 for the quarter ended September 30, 2025, compared to $1,703,000 for the prior quarter and $1,846,000 for the same period last year. The increases compared to prior periods was mainly due to a one-time gain from a life insurance policy redemption, combined with increased production from our investment advisory service and related fee income, and increased service charge income on deposit accounts.

Non-interest expense totaled $12,700,000 for the quarter ended September 30, 2025, compared to $12,688,000 in the prior quarter and $11,324,000 in the same quarter a year ago. Compared to the prior quarter, non-interest expense was essentially flat. The third quarter increase compared to the same period a year ago is primarily due to staffing expense and general operating costs related to servicing the growing loan and deposit portfolios. Our full-time equivalent employees grew by six during the third quarter in preparation of our 19^th full-service branch which opened in Lodi on October 2, 2025. “Our team continues to execute on our growth strategy while maintaining excellent asset quality and customer relationships,” commented Chris Courtney, Chief Executive Officer. “The opening of our new Lodi branch demonstrates our focus on expanding our presence across the Central Valley.”

Total assets were $2.00 billion at September 30, 2025, an increase of $74.5 million and $95.0 million over June 30, 2025 and September 30, 2024, respectively. Gross loans were $1.11 billion at September 30, 2025, an increase of $3.0 million and $37.7 million over June 30, 2025 and September 30, 2024, respectively. The Company’s total deposits were $1.77 billion as of September 30, 2025, an increase of $63.6 million and $84.6 million from June 30, 2025 and September 30, 2024, respectively. Our liquidity position is very strong as evidenced by $247.2 million in cash and cash equivalents balances at September 30, 2025.

Non-performing assets (“NPA”) remained at zero as of September 30, 2025, as they were for all of 2025 and 2024. The allowance for credit losses (“ACL”) as a percentage of gross loans was 1.03% at September 30, 2025, compared to 1.03% at June 30, 2025 and 1.07% at September 30, 2024. The decrease in the ACL as a percentage of gross loans from last year is partially due to the growth in the loan portfolio. Management has performed a thorough analysis of credit risk as part of the Current Expected Credit Loss (CECL) model’s ACL computation, concluding that the credit loss reserves relative to gross loans remain at acceptable levels, and credit quality remains stable. The Company recorded a reversal of provision for credit losses of $60,000 during the third quarter which was related to a decrease in unfunded loan commitments.
