Arrow Reports 1st Quarter Net Income of $6.3 Million, or $0.38 per Share, and Declares 2nd Quarter Dividend of $0.28 per Share

GLENS FALLS, N.Y. (May 1, 2025) – Arrow Financial Corporation (NasdaqGS® – AROW) ("Arrow" or "the Company") announced financial results for the three-month period ended March 31, 2025. Reported net income for the first quarter of 2025 was $6.3 million and fully diluted earnings per share ("EPS") was $0.38, versus $4.5 million and EPS of $0.27 for the fourth quarter of 2024.

The Board of Directors of Arrow declared a quarterly cash dividend of $0.28 per share payable May 23, 2025 to shareholders of record as of May 13, 2025.

The quarter was adversely impacted by the recognition of a specific reserve of $3.75 million ($0.17 per share) related to a $15 million commercial real estate loan participation secured by properties in two office parks in upstate New York, where Arrow is a 22% participant in a $67 million multi-bank lending facility as previously reported in a Form 8-K filed April 16, 2025.

This quarter's results also reflect approximately $0.6 million ($0.03 per share) of non-core unification costs related to Arrow’s planned July 2025 system conversion and operational merger of its two banking subsidiaries.

This Earnings Release and related commentary should be read in conjunction with the Company's May 1, 2025 Form 8-K and related First 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:

“We delivered another quarter of strong margin expansion along with continued loan growth, further improving core profitability during these volatile economic times. We continue to execute on our strategic initiatives for continued growth, including expanding our Corporate Banking Team in the Capital Region of New York state. Our overall credit quality remains extremely strong, despite the recent development in one of our larger commercial credit exposures. We believe this to be an isolated incident as all credit metrics outside of this particular exposure are trending favorably. Furthermore, we are moving closer to finalizing our bank unification efforts to better serve our growing market and drive stronger operating performance under one brand.”

1

•Net Interest Margin improved to 3.07% (3.08% FTE1), up from 2.83% (2.85% FTE) in the prior quarter

•Year-to-date loan growth of approximately $22 million2 (2.5% annualized), despite an increase in loan pay-offs and sale activity

•Quarter-end loan exit rates increased to 5.45% at March 31, 2025 vs. 5.40% at December 31, 2024

•Tangible Book Value increased to $22.72

Income Statement

•Net Income: Net income for the first quarter of 2025 was $6.3 million, increasing from $4.5 million in the fourth quarter of 2024.

◦Compared to the prior quarter, net income benefited from an increase of $1.7 million in net interest income and an increase in non-interest income of $3.6 million, partially offset by an increase in the provision for credit losses of $2.2 million and a slight increase in non-interest expense of $207 thousand.

•Net Interest Income: Net interest income for the first quarter of 2025 was $31.4 million, increasing 5.6% from $29.7 million for the fourth quarter of 2024.

◦Total interest and dividend income was $50.4 million for the first quarter of 2025, a decrease from $50.9 million in the fourth quarter of 2024. Interest expense for the first quarter of 2025 was $19.0 million, a decrease from $21.2 million for the fourth quarter of 2024. The decrease in interest expense from the prior quarter was driven primarily by active management of deposit rates, partially offset by changes in deposit composition.

•Net Interest Margin: Net interest margin, on an FTE basis, for the first quarter of 2025 increased to 3.08%, compared to 2.85% for the fourth quarter of 2024. The increase in net interest margin compared to the fourth quarter in 2024 was primarily the result of continued yield expansion on earning assets combined with the moderating cost of interest-bearing liabilities. Net interest margin is negatively affected by deposits continuing to migrate to higher cost products, such as money market savings and time deposits, while being positively impacted by repricing of higher cost time deposits.

1 FTE Net interest margin is a non-GAAP measure. See reconciliation on Note 3 to the Selected Quarterly Information.

2 Includes both $3.3 million fair value hedge adjustment at March 31, 2025 and $2.2 million fair value hedge adjustment at December 31, 2024.

•Provision for Credit Losses: For the first quarter of 2025, the provision for credit losses was $5.0 million compared to $2.9 million in the fourth quarter of 2024. The primary driver of the increase was Arrow's recognition of a $3.75 million specific reserve on a $15 million commercial real estate loan. Other drivers for the provision for credit losses in the first quarter of 2025 were charge-offs, growth in loan balances and changes to the economic forecast factors embedded in the credit loss allowance model. Subsequent to March 31, 2025, the bank group foreclosed on the collateral related to the above referenced commercial real estate loan.

•Non-Interest Income: Non-interest income for the three months ended March 31, 2025, was $7.8 million, an increase from $4.2 million in the fourth quarter of 2024. The increase from the prior quarter was primarily attributable to the absence of a $3.0 million pre-tax loss related to the investment portfolio repositioning as well as a $0.7 million pre-tax charge related to legacy branding, both recognized in the fourth quarter of 2024.

•Non-Interest Expense: Non-interest expense for the first quarter of 2025 was $26.0 million, an increase from $25.8 million in the fourth quarter of 2024. The first quarter of 2025 included unification expenses of approximately $0.6 million. The unification expenses were primarily comprised of project management and information technology costs related to the July 2025 system conversion. Arrow continues to focus on overall expense management.

•Provision for Income Taxes: The provision for income taxes and effective tax rate were $1.8 million and 22.4%, for the first quarter of 2025, and $0.8 million and 14.4%, for the fourth quarter of 2024. The increase in the effective tax rate from the fourth quarter of 2024 was primarily attributable to the change in pre-tax income combined with a change in the amount of tax advantaged earning assets as a percentage of total earning assets.

Balance Sheet

•Total Assets: Total assets were $4.4 billion at March 31, 2025, an increase of $142.5 million, or 3.3%, as compared to December 31, 2024. For the first quarter of 2025, overall growth in the balance sheet was attributable to changes in cash balances, primarily from seasonal municipal and corporate deposits, as well as growth in the loan portfolio.

•Investments: Total investments were $553.0 million as of March 31, 2025, a decrease of $17.8 million, or 3.1%, compared to December 31, 2024. The decrease from December 31, 2024 was driven primarily by paydowns and maturities. There were no credit quality issues related to the investment portfolio.

3

•Loans3: Total loans were $3.4 billion as of March 31, 2025. Loan growth for the first quarter of 2025 was $22.3 million. Loan growth was primarily driven by an increase in residential real estate 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 $37.8 million as of March 31, 2025, which represented 1.11% of loans outstanding, as compared to $33.6 million, or 0.99%, at December 31, 2024. The increase in the allowance for credit losses was primarily driven by the recognition of the specific reserve of $3.75 million. Excluding the specific reserve, the coverage ratio for the allowance for credit loses was 1.00%. Net charge-offs, expressed as an annualized percentage of average loans outstanding, were 0.10% for the three-month period ended March 31, 2025, as compared to 0.06% for the three-month period ended December 31, 2024. Nonperforming assets were $19.5 million as of March 31, 2025, representing 0.44% of period-end assets, compared to 0.50% at December 31, 2024.

•Deposits: At March 31, 2025, deposit balances were $4.0 billion, an increase of $140.2 million from December 31, 2024. The increase from December 31, 2024 was primarily attributable to the seasonality of municipal deposits as well as an additional $125.0 million of brokered CDs. The brokered CDs partially replaced previous wholesale funding sources and are part of a cash flow hedge using interest rate swaps to reduce overall funding costs. Please refer to page 7 for further details related to deposits.

•Capital: Total stockholders’ equity was $404.4 million at March 31, 2025, an increase of $3.5 million, or 0.9%, from December 31, 2024. The increase from December 31, 2024 was primarily attributable to net income of $6.3 million and other comprehensive income of $4.9 million offset by dividends of $4.7 million and share repurchases of $3.4 million. Arrow's regulatory capital ratios remain strong. As of March 31, 2025, Arrow's Common Equity Tier 1 Capital Ratio was 12.59% and Total Risk-Based Capital Ratio was 14.48%. The capital ratios of Arrow and its subsidiary bank continued to exceed the “well capitalized” regulatory standards.

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.

			Net Interest Margin (Non-GAAP)*			3.08		%				2.85		%				2.79		%				2.69		%				2.62		%
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 March 31, 2025 CET1 ratio listed in the tables (i.e., 12.59%) exceeds the sum of the required minimum CET1 ratio plus the fully phased-in Capital Conservation Buffer (i.e., 7.00%).

			Common Equity Tier 1 Capital			395,900						397,285						397,122						395,691						391,706
