Income Statement

• Net Income:Net income for the second quarter of 2026 was $11.0 million, decreasing from $13.5 million in the first quarter of 2026.

  • Compared to the prior quarter, net income decreased primarily due to an increase in the provision for credit losses of $2.3 million, including $1.6 million related to a specific reserve for a commercial loan where the borrower and guarantors entered into bankruptcy during the quarter. Net income was also impacted by a decrease in non-interest income of $0.4 million, an increase in MRE of $0.2 million and lower net interest income of $0.2 million. The decreases were partially offset by lower income tax expenses of $0.9 million.
    
    

• Net Interest Income:Net interest income for the second quarter of 2026 was $35.9 million, decreasing 0.6% from the first quarter of 2026.

  • Total interest and dividend income was $53.6 million for the second quarter of 2026, a decrease from $53.8 million in the first quarter of 2026. The decrease was attributable to lower average earning assets throughout the quarter as well as the increase in non-performing loans. Interest expense for the second quarter of 2026 was $17.7 million, consistent with the first quarter of 2026 as lower deposit costs were offset by timing and a change in the mix of deposit balances toward higher cost deposits.
    
    

• Net Interest Margin:Net interest margin, on an FTE basis, for the second quarter of 2026 decreased to 3.43%, compared to 3.48% for the first quarter of 2026. The decrease in net interest margin compared to the first quarter of 2026 was primarily the result of a seasonal change in the deposit mix toward higher costing interest-bearing liabilities. Net interest margin was also impacted by the reversal of interest income related to the aforementioned commercial loan migrating to non-performing.

• Provision for Credit Losses:For the second quarter of 2026, the provision for credit losses was $2.8 million compared to $0.5 million in the first quarter of 2026, primarily driven by a $1.6 million specific reserve related to the non-performing commercial loan as well as an increase to the provision due to loan growth in the second quarter of 2026.
  
  

• Non-Interest Income:Non-interest income for the three months ended June 30, 2026, was $8.3 million, a decrease from $8.6 million in the first quarter of 2026. The decrease was the result of the season fluctuation of insurance premiums of $0.1 million as well as a $0.3 million charge related to the impairment of a property held for future use. This was partially offset by an increase in interchange fees from the linked quarter and a positive equity position valuation adjustment of approximately $0.2 million
  
  

• Non-Interest Expense:Non-interest expense for the second quarter of 2026 was $27.5 million, an increase from $26.9 million in the first quarter of 2026. The second quarter of 2026 included approximately $1.0 million of MRE versus $0.8 million in the first quarter of 2026.
  
  

• Provision for Income Taxes: The provision for income taxes and effective tax rate were $2.9 million and 21.1%, respectively for the second quarter of 2026, and $3.9 million and 22.3%, respectively for the first quarter of 2026. The lower tax expense was driven by lower pre-tax income and a lower effective tax rate. The effective tax rate for the second quarter of 2026 reflects the impact of tax credits recognized from energy production tax credit purchases made in June 2026 offset by nondeductible expenses related to the acquisition of Adirondack Bancorp, Inc. and Adirondack Bank.

Balance Sheet

• Total Assets: Total assets were $4.5 billion at June 30, 2026, a decrease of $39.7 million, or 0.9%, as compared to March 31, 2026. For the second quarter of 2026, the overall change in asset was driven by a decline in cash balances attributable to a net decrease in deposits. 
  
  

• Investments: Total investments were $587.9 million as of June 30, 2026, a decrease of $6.6 million, or 1.1%, compared to March 31, 2026. The decrease from March 31, 2026 was driven primarily by paydowns and maturities. There were no material credit quality issues related to the investment portfolio. 
  
  

• Loans:Total loans were $3.5 billion as of June 30, 2026. Loans outstanding increased in the second quarter of 2026 by $57.6 million, driven by growth in commercial loans. Please see the loan detail included in the Consolidated Financial Information  table on page 14.
  
  

• Allowance for Credit Losses:The allowance for credit losses was $36.2 million as of June 30, 2026, which represented 1.03% of loans outstanding, as compared to $34.1 million, or 0.99% of loans outstanding, at March 31, 2026. The increase in the allowance was the result of a $1.6 million specific reserve related to the previously referenced non-performing commercial loan as well as an increase to the allowance for growth in the loan portfolio, partially offset by charge-offs. Net charge-offs, expressed as an annualized percentage of average loans outstanding, were 0.08% for the three-month period ended June 30, 2026, as compared to 0.10% for the three-month period ended March 31, 2026. Nonperforming assets were $8.7 million as of June 30, 2026, representing 0.19% of period-end assets, an increase from $4.9 million, or 0.11%, at March 31, 2026. Nonperforming assets increased due to the $3.8 million non-performing commercial loan previously referenced.
  
  

• Deposits: At June 30, 2026, deposit balances were $3.7 billion, a decrease of $358.7 million from March 31, 2026. The change from March 31, 2026 was primarily attributable to $300 million of brokered CDs, being replaced by lower costing FHLB borrowings. In addition, the seasonality of municipal deposits contributed to decreased deposits in the quarter. Please refer to page 7 for further details related to deposits.
  
  

• Capital:Total stockholders' equity was $446.3 million at June 30, 2026, an increase of $6.2 million, or 1.4%, from March 31, 2026. The increase from March 31, 2026 was primarily attributable to net income of $11.0 million and other stock-based activity of $0.8 million offset by other comprehensive loss of $0.6 million and dividends of $5.0 million. Arrow's regulatory capital ratios remain strong. As of June 30, 2026, Arrow's Common Equity Tier 1 Capital Ratio was 13.21% and Total Risk-Based Capital Ratio was 14.98%. The capital ratios of Arrow and its subsidiary bank continued to exceed the "well capitalized" regulatory standards. Regulatory capital ratios are preliminary, subject to finalization as part of the current quarter Call Report.
