Priscilla Sims Brown, President and Chief Executive Officer, commented, “Amalgamated is a conservatively managed bank with a simple model, prudent asset liability management practices, efficient operations, experienced management, strong asset quality and, importantly, a uniquely stable deposit base which is beginning to benefit from strong political deposit inflows as the presidential election cycle begins.” Second Quarter Earnings Net income for the second quarter of 2023 was $21.6 million, or $0.70 per diluted share, compared to $21.3 million, or $0.69 per diluted share, for the first quarter of 2023. The $0.3 million increase for the second quarter of 2023 compared to the preceding quarter was primarily driven by a $2.7 million increase in non-interest income, a $1.1 million decrease in provision expense, and a $1.1 million decrease in non-interest expense offset by a $4.3 million decrease in net interest income, and a $0.2 million increase in income tax expense. Core net income excluding the impact of solar tax equity investments (non-GAAP)1 for the second quarter of 2023 was $22.0 million, or $0.72 per diluted share, compared to $23.0 million, or $0.74 per diluted share, for the first quarter of 2023. Excluded from core net income for the second quarter of 2023 were $0.3 million of pre-tax losses on sales of securities and $0.3 million in severance costs. Excluded from the first quarter of 2023 were $3.1 million of pre-tax losses on the sale of securities and $0.8 million of pre-tax gains on subordinated debt repurchases. Net interest income was $63.0 million for the second quarter of 2023, compared to $67.3 million for the first quarter of 2023. Interest income on securities decreased $0.2 million driven by a 12 basis point increase in securities yield offset by a decrease in the average balance of securities of $102.0 million. Loan interest income increased $0.6 million driven by a $73.5 million increase in average loan balances offset by a 7 basis point decrease in loan yields. The increase in interest income was offset by higher interest expense on deposits of $5.0 million driven by a 45 basis point increase in deposit costs and an increase in the average balance of interest-bearing deposits of $165.5 million. The changes in deposit costs were primarily related to a $43.8 million increase in average Brokered CDs and a $112.5 million increase in average savings, NOW, and money market deposits. Net interest margin was 3.33% for the second quarter of 2023, a decrease of 26 basis points from 3.59% in the first quarter of 2023. The decrease is largely due to increased rates and average balances of interest-bearing liabilities, primarily costs for deposits. No prepayment penalties were earned in loan income in the first or second quarter of 2023. Provision for credit losses totaled $3.9 million for the second quarter of 2023 compared to $5.0 million in the first quarter of 2023. The decrease in the provision is largely due to a $1.2 million impairment charge on a Silicon Valley Bank (“SIVB”) senior note in the first quarter of 2023, which was subsequently sold during the second quarter. Core non-interest income excluding the impact of solar tax equity investments (non-GAAP)1 was $8.2 million for the second quarter of 2023, compared to $7.5 million in the first quarter of 2023. The increase of $0.7 million was primarily related to increased income from equity investments, higher Trust Department fees, and fees on treasury investments for certain clients seeking alternative yields to deposit pricing. Core non-interest expense (non-GAAP)1 for the second quarter of 2023 was $37.2 million, a decrease of $1.4 million from the first quarter of 2023. This was primarily driven by a $0.8 million decrease in compensation and employee benefits comprised mainly of increased payroll taxes given timing of corporate incentive payments, temporary personnel costs, and benefit insurance costs incurred during the first quarter of 2023. Additionally, advertising expense and data processing expense decreased during the quarter, offset by increased reserves for FDIC depository insurance and increased professional fees. 2

Our provision for income tax expense was $7.8 million for the second quarter of 2023, compared to $7.6 million for the first quarter of 2023. The increase reflects the higher pre-tax income in the second quarter. Our effective tax rate for the second quarter of 2023 was 26.5%, compared to 26.2% for the first quarter of 2023. Balance Sheet Quarterly Summary Total assets were $7.8 billion at June 30, 2023, compared to $7.8 billion at March 31, 2023, in keeping with our strategy to keep our balance sheet flat. Notable changes within individual balance sheet line items include a $53.5 million increase in loans receivable, net of deferred loan origination costs, funded mainly by a $58.9 million decrease in available-for-sale investment securities, and a $15.4 million decrease in resell agreements. Additionally, Brokered CDs declined by $126.4 million, offset by a $90.0 million increase in short-term borrowings. Total loans receivable, net of deferred loan origination costs at June 30, 2023 were $4.3 billion, an increase of $53.5 million, or 1.3%, compared to March 31, 2023. The increase in loans is primarily driven by a $32.9 million increase in multifamily loans, a $25.6 million increase in commercial and industrial loans, a $5.9 million increase in the commercial real estate portfolio, offset by a $1.6 million decrease in residential loans, and a $9.2 million decrease in construction loans. During the quarter we had $5.2 million of payoffs and upgrades of criticized or classified loans, including a payoff of a $3.8 million office related loan, as we continue to focus on the improving the credit quality of the commercial portfolio. Deposits at June 30, 2023 were $6.9 billion, a decrease of $146.7 million, or 2.1%, as compared to $7.0 billion as of March 31, 2023. Deposits excluding Brokered CDs decreased by $20.3 million to $6.4 billion, a 0.3% decrease compared to March 31, 2023. Deposits held by politically active customers, such as campaigns, PACs, advocacy-based organizations, and state and national party committees were $835.8 million as of June 30, 2023, an increase of $157.7 million compared to $678.1 million as of March 31, 2023. Non-interest-bearing deposits represented 45% of average total deposits and 43% of ending total deposits for the quarter ended June 30, 2023, contributing to an average cost of total deposits of 110 basis points. Nonperforming assets totaled $35.3 million, or 0.45% of period-end total assets at June 30, 2023, a decrease of $3.4 million, compared with $38.7 million, or 0.49% on a linked quarter basis. The decrease in non-performing assets was primarily driven by the $1.8 million SIVB senior note placed on nonaccrual status in the first quarter of 2023, which was subsequently sold in the second quarter, and a $1.3 million commercial real estate loan that was 90 days past due and accruing at March 31, 2023 was brought current in the second quarter. Additionally, a $1.7 million commercial loan was charged off in the quarter which was substantially reserved for as of the first quarter, offset by an additional $1.4 million in retail loans that were placed on nonaccrual status. During the quarter, the allowance for credit losses on loans increased $0.1 million to $67.4 million at June 30, 2023 from $67.3 million at March 31, 2023. The ratio of allowance to total loans was 1.59%, a decrease of 2 basis points from 1.61% in the first quarter of 2023. Capital Quarterly Summary As of June 30, 2023, our Common Equity Tier 1 Capital Ratio was 12.51%, Total Risk-Based Capital Ratio was 15.26%, and Tier-1 Leverage Capital Ratio was 7.78%, compared to 12.23%, 15.00%, and 7.50%, respectively, as of March 31, 2023. Stockholders’ equity at June 30, 2023 was $528.6 million, compared to $519.2 million at March 31, 2023. The increase in stockholders’ equity was primarily driven by $21.6 million of net income for the quarter offset by a $7.9 million increase in accumulated other comprehensive loss due to the tax effected mark-to-market on our available for sale securities portfolio. Our tangible book value per share was $16.78 as of June 30, 2023 compared to $16.42 as of March 31, 2023. Tangible common equity was 6.59% of tangible assets, compared to 6.43% as of March 31, 2023. 3
