Priscilla Sims Brown, President and Chief Executive Officer, commented, “We are operating in an enviable position of managing deposit liquidity instead of searching for it. In today's highly constrained liquidity environment, we are punching well above our weight, giving us many options to deliver above peer returns.” Fourth Quarter Earnings Net income for the fourth quarter of 2023 was $22.7 million, or $0.74 per diluted share, compared to $22.3 million, or $0.73 per diluted share, for the third quarter of 2023. The $0.4 million increase during the quarter was primarily driven by a $3.6 million increase in net interest income and a $2.6 million increase in non-interest income, offset by a $1.8 million increase in provision for credit losses, and a $3.7 million increase in income tax expense primarily driven by a state and city tax examination that reduced the Bank’s net operating loss carryforwards, which resulted in additional tax liabilities and a write-down of deferred tax assets totaling $3.3 million. Core net income1 for the fourth quarter of 2023 was $22.1 million, or $0.72 per diluted share, compared to $23.3 million, or $0.76 per diluted share, for the third quarter of 2023. Excluded from core net income for the quarter, pre-tax was $2.3 million of losses on the sale of securities, and $3.3 million of tax credits from our solar tax equity investments. Excluded from the third quarter of 2023, pre-tax was $1.7 million of losses on the sale of securities, $0.6 million of pre-tax gains on subordinated debt repurchases, and $0.3 million in severance costs. Net interest income was $67.3 million for the fourth quarter of 2023, compared to $63.7 million for the third quarter of 2023. Loan interest income increased $2.0 million driven by a $56.2 million increase in average loan balances coupled with a 12 basis point increase in loan yields. Interest income on securities increased $1.8 million driven by a 27 basis point increase in securities yield offset by a decrease in the average balance of securities of $32.6 million. The increase in interest income was offset by higher interest expense on total interest-bearing deposits of $2.2 million driven by a 14 basis point increase in cost and an increase in the average balance of total interest-bearing deposits of $128.7 million. The changes in deposit costs were primarily related to increased rates on select non-time deposit products and also a 55 basis point increase in the cost of time deposits. Net interest margin was 3.44% for the fourth quarter of 2023, an increase of 15 basis points from 3.29% in the third quarter of 2023. The increase is largely due to increased yields and average balances of interest-earning assets driven mainly by strong PACE originations and commercial lending portfolio repricing. Prepayment penalties had no impact on our net interest margin in the fourth quarter of 2023, which is the same as in the prior quarter. Provision for credit losses totaled an expense of $3.8 million for the fourth quarter of 2023 compared to an expense of $2.0 million in the third quarter of 2023. The expense in the fourth quarter is primarily driven by $4.7 million charge-off on a construction loan, partially offset by improvements in macro-economic forecasts used in the CECL model. 2

Core non-interest income1 was $8.5 million for the fourth quarter of 2023, compared to $7.8 million in the third quarter of 2023. The increase was primarily related to fees from our treasury investment services as well as fees earned from off- balance sheet reciprocal deposits. Core non-interest expense1 for the fourth quarter of 2023 was $37.7 million, an increase of $0.7 million from the third quarter of 2023. This was mainly driven by a $0.2 million increase in professional fees, and a $0.4 million increase in other expense primarily related to residential loan servicing expenses. Our provision for income tax expense was $12.5 million for the fourth quarter of 2023, compared to $8.8 million for the third quarter of 2023. The increase is primarily driven by a $3.3 million adjustment related to a state and city tax examination as previously mentioned. Excluding the tax adjustment, our effective tax rate for the fourth quarter of 2023 was 26.2%, compared to 28.4% for the third quarter of 2023. Balance Sheet Quarterly Summary Total assets were $8.0 billion at December 31, 2023, compared to $7.9 billion at September 30, 2023, in keeping with our strategy to keep our balance sheet flat. Notable changes within individual balance sheet line items include a $48.7 million increase in net loans receivable, and a $50.0 million increase in resell agreements. Additionally, deposits excluding Brokered CDs increased by $170.8 million while Brokered CDs decreased $149.7 million. Total net loans receivable, at December 31, 2023 were $4.3 billion, an increase of $48.7 million, or 1.1% for the quarter. The increase in loans is primarily driven by a $53.2 million increase in multifamily loans, a $29.3 million increase in the commercial real estate portfolio, and a $16.1 million increase in residential loans, offset by a $39.4 million decrease in commercial and industrial loans, mainly related to paydowns on revolving lines. During the quarter, criticized or classified loans increased $22.0 million largely related to the downgrade of an $18.7 million commercial and industrial loan to substandard and accruing. Total deposits at December 31, 2023 were $7.0 billion, an increase of $21.1 million, or 0.3%, during the quarter. Total deposits excluding Brokered CDs increased by $170.8 million to $6.8 billion, or a 2.6% increase. Deposits held by politically active customers, such as campaigns, PACs, advocacy-based organizations, and state and national party committees were $1.2 billion as of December 31, 2023, an increase of $236.1 million during this quarter, of which a substantial portion were moved off-balance sheet. Non-interest-bearing deposits represented 41% of average total deposits and 42% of ending total deposits for the quarter, contributing to an average cost of total deposits of 143 basis points. Super- core deposits1 totaled approximately $3.6 billion, had a weighted average life of 16 years, and comprised 53% of total deposits, excluding Brokered CDs. Total uninsured deposits were $4.0 billion, comprising 58% of total deposits. Excluding uninsured super-core deposits of approximately $2.6 billion, remaining uninsured deposits were approximately 21%-24% of total deposits with immediate liquidity coverage of 202%. Nonperforming assets totaled $34.2 million, or 0.43% of period-end total assets at December 31, 2023, a decrease of $2.3 million, compared with $36.5 million, or 0.46% on a linked quarter basis. The decrease in nonperforming assets was primarily driven by a charge-off of a $4.7 million construction loan and sale of a $1.2 million multifamily loan held for sale, offset by a $4.2 million increase in residential real estate nonaccrual loans. During the quarter, the allowance for credit losses on loans decreased $2.1 million to $65.7 million. The ratio of allowance to total loans was 1.49%, a decrease of 6 basis points from 1.55% in the third quarter of 2023. 3

Capital Quarterly Summary As of December 31, 2023, our Common Equity Tier 1 Capital ratio was 12.98%, Total Risk-Based Capital ratio was 15.64%, and Tier-1 Leverage Capital ratio was 8.07%, compared to 12.63%, 15.28% and 7.89%, respectively, as of September 30, 2023. Stockholders’ equity at December 31, 2023 was $585.4 million, an increase of $39.1 million during the quarter. The increase in stockholders’ equity was primarily driven by $22.7 million of net income for the quarter offset by $3.1 million in dividends paid at $0.10 per outstanding share, $1.1 million of common stock repurchases, and a $19.3 million improvement in accumulated other comprehensive loss due to the tax effected mark-to-market on our available for sale securities portfolio. Tangible book value per share was $18.74 as of December 31, 2023 compared to $17.43 as of September 30, 2023. Tangible common equity improved to 7.16% of tangible assets, compared to 6.72% as of September 30, 2023.

Our management utilizes this information to compare our operating performance for December 31, 2023 versus certain periods in 2023 and 2022 and to prepare internal projections. We believe these non-GAAP financial measures facilitate making period-to-period comparisons and are meaningful indications of our operating performance.

The presentation of non-GAAP financial information, however, is not intended to be considered in isolation or as a substitute for GAAP financial measures.

Terminology Certain terms used in this release are defined as follows: “Core efficiency ratio” is defined as “Core non-interest expense” divided by “Core operating revenue.” We believe the most directly comparable performance ratio derived from GAAP financial measures is an efficiency ratio calculated by dividing total non-interest expense by the sum of net interest income and total non-interest income. “Core net income” is defined as net income after tax excluding gains and losses on sales of securities, gains on the sale of owned property, costs related to branch closures, restructuring/severance costs, acquisition costs, tax credits and accelerated depreciation on solar equity investments, and taxes on notable pre-tax items.

We believe the most directly comparable GAAP financial measure is non-interest income. “Core operating revenue” is defined as total net interest income plus “core non-interest income”. We believe the most directly comparable GAAP financial measure is the total of net interest income and non-interest income. “Core return on average assets” is defined as “Core net income” divided by average total assets. We believe the most directly comparable performance ratio derived from GAAP financial measures is return on average assets calculated by dividing net income by average total assets. “Core return on average tangible common equity” is defined as “Core net income” divided by average “tangible common equity.” We believe the most directly comparable performance ratio derived from GAAP financial measures is return on average equity calculated by dividing net income by average total stockholders’ equity. “Super-core deposits” are defined as total deposits from commercial and consumer customers, with a relationship length of greater than 5 years. We believe the most directly comparable GAAP financial measure is total deposits. 5
