Arrow Reports 3rd Quarter Net Income of $12.8 Million, or $0.77 per Share, and Declares 4th Quarter Dividend of $0.29 per Share

GLENS FALLS, N.Y. (October 30, 2025) – Arrow Financial Corporation (NasdaqGS® – AROW) ("Arrow" or "the Company") announced financial results for the three-month period ended September 30, 2025. Reported net income for the third quarter of 2025 was $12.8 million and fully diluted earnings per share ("EPS") was $0.77, versus net income of $10.8 million and EPS of $0.65 for the second quarter of 2025.

The Board of Directors of Arrow declared a quarterly cash dividend of $0.29 per share; payable November 24, 2025 to shareholders of record as of November 12, 2025.

This quarter's results include approximately $600 thousand ($0.03 per share) of non-core unification costs related to Arrow’s system conversion and operational merger of its two banking subsidiaries, which were successfully completed in July 2025. Arrow does not expect to incur additional costs related to the unification effort.

This Earnings Release and related commentary should be read in conjunction with the Company's October 30, 2025 Form 8-K and related Third Quarter 2025 Investor Presentation, which can also be found on Arrow's website: arrowfinancial.com/documents/investor-presentations.

Arrow President and CEO David S. DeMarco:

"I am proud to report that on the heels of our unification effort, the Arrow team delivered a great financial quarter. EPS increased by almost 20% from the prior quarter and ROA improved by 16 bps to 1.16%, despite recognizing the last remaining unification expenses. Our third quarter delivered record net interest income, solid net interest margin expansion and more than 10% annualized growth in tangible book value. With the Federal Reserve enacting a first round of interest rate cuts late in the third quarter and again in late October, Arrow is well-positioned with our near-term liability sensitive balance sheet to deliver another great quarter to end the year. We are delighted that we can use our improved financial performance to continue to support our communities while delivering strong results to our shareholders."

Balance Sheet

•Total Assets: Total assets were $4.6 billion at September 30, 2025, an increase of $172.4 million, or 3.9%, as compared to June 30, 2025. For the third quarter of 2025, the overall change in the balance sheet was primarily attributable to the seasonal surge in municipal deposits as well as fluctuations in cash balances, maturities of investments and growth in the loan portfolio.

•Investments: Total investments were $558.4 million as of September 30, 2025, an increase of $30.0 million, or 5.7%, compared to June 30, 2025. The increase from June 30, 2025 was driven primarily by $48 million of additional investments offset by paydowns and maturities. There were no credit quality issues related to the investment portfolio.

•Loans4: Total loans were $3.4 billion as of September 30, 2025. Loan growth for the third quarter of 2025 was $17.3 million. Loan growth was primarily driven by an increase in residential real estate loans and commercial loans. Please see the loan detail included in the Consolidated Financial Information table on page 12.

•Allowance for Credit Losses: The allowance for credit losses was $34.2 million as of September 30, 2025, which represented 0.99% of loans outstanding, as compared to $34.2 million, or 1.00% of loans outstanding, at June 30, 2025. Net charge-offs, expressed as an annualized percentage of average loans outstanding, were 0.10% for the three-month period ended September 30, 2025, as compared to 0.49% for the three-month period ended June 30, 2025. The decrease was the result of a charge-off of a previously reserved commercial loan participation in the second quarter of 2025. Nonperforming assets were $6.7 million as of September 30, 2025, representing 0.15% of period-end assets, compared to $6.8 million, or 0.15%, at June 30, 2025.

•Deposits: At September 30, 2025, deposit balances were $4.1 billion, an increase of $170.7 million from June 30, 2025. The change from June 30, 2025 was primarily attributable to the seasonality of municipal deposits. Please refer to page 6 for further details related to deposits.

1.			Non-GAAP Financial Measure Reconciliation: Tangible Book Value, Tangible Equity, and Return on Tangible Equity exclude goodwill and other intangible assets, net from total equity.  These are non-GAAP financial measures, which Arrow believes provide investors with information that is useful in understanding its financial performance.

2.			Non-GAAP Financial Measure Reconciliation: Net Interest Margin is the ratio of annualized tax-equivalent net interest income to average earning assets. This is also a non-GAAP financial measure, which Arrow believes provides investors with information that is useful in understanding its financial performance.
						9/30/2025						6/30/2025						12/31/2024						12/31/2024						9/30/2024

			Net Interest Margin (Non-GAAP)*			3.24		%				3.16		%				3.08		%				2.85		%				2.79		%
3.			Non-GAAP Financial Measure Reconciliation: Financial Institutions often use the "efficiency ratio", a non-GAAP ratio, as a measure of expense control. Arrow believes the efficiency ratio provides investors with information that is useful in understanding its financial performance. Arrow defines efficiency ratio as the ratio of non-interest expense to net gross income (which equals tax-equivalent net interest income plus non-interest income, as adjusted).
4.			For the current quarter, all of the regulatory capital ratios as well as the Total Risk-Weighted Assets are calculated in accordance with bank regulatory capital rules. The September 30, 2025 CET1 ratio listed in the tables (i.e., 13.07%) exceeds the sum of the required minimum CET1 ratio plus the fully phased-in Capital Conservation Buffer (i.e., 7.00%). Regulatory capital ratios are estimated, subject to finalization as part of the current quarter Call Report.
