Second Quarter Earnings Net income for the second quarter of 2024 was $26.8 million, or $0.87 per diluted share, compared to $27.2 million, or $0.89 per diluted share, for the first quarter of 2024. The $0.4 million decrease during the quarter was primarily driven by $3.6 million decrease in non-core income from solar tax equity investments, which was expected, and a $1.4 million increase in non-interest expense. This was offset by a $2.3 million decrease in income tax expense, a $2.0 million increase in non-core ICS One-Way Sell fee income from our off-balance sheet deposits, and a $1.2 million increase in net interest income. Core net income1 for the second quarter of 2024 was $26.2 million, or $0.85 per diluted share, compared to $25.6 million, or $0.83 per diluted share, for the first quarter of 2024. Excluded from core net income for the quarter, pre-tax, was $4.9 million of ICS One-Way Sell fee income, $2.7 million of losses on the sale of securities, $1.8 million of accelerated depreciation from solar tax equity investments, $0.4 million of gains on subordinated debt repurchases, and $44 thousand in severance costs. Excluded from core net income for the first quarter of 2024, pre-tax, was $2.9 million of ICS One-Way Sell fee income, $2.8 million of losses on the sale of securities, $1.8 million of tax credits from our solar tax equity investments, $0.5 million in gains on the settlement of a lease termination, and $0.2 million in severance costs. Net interest income was $69.2 million for the second quarter of 2024, compared to $68.0 million for the first quarter of 2024. Loan interest income decreased $0.7 million and loan yields decreased 8 basis points as a result of $2.1 million of accelerated amortization related to purchase premiums associated with the payoff of a C&I loan relationship, offset by a $16.4 million increase in average loan balances. Interest income on securities increased $1.9 million driven by an increase in the average balance of securities of $138.5 million. Interest income on resell agreements increased $0.7 million driven by a $43.6 million increase in the average balance. The overall increase in interest income was offset by higher interest expense on total interest-bearing deposits of $3.0 million driven by a 22 basis point increase in cost and by an increase in the average balance of total interest-bearing deposits of $126.7 million. The changes in deposit costs were primarily related to increased rates on money market products and select non-time deposit accounts and a 26 basis point increase in the cost of time deposits. The increase in the average balance of interest-bearing deposits was primarily driven by strong deposit growth across both political and non-political sectors, partially offset by a decrease in the average balance of higher cost borrowings of $183.5 million. Net interest margin was 3.46% for the second quarter of 2024, a decrease of 3 basis points from 3.49% in the first quarter of 2024. The decrease is attributable to $2.1 million of accelerated amortization related to purchase premiums associated with the payoff of a C&I loan relationship as mentioned above, which had an approximate 10 basis point constrictive impact on net interest margin in the quarter. Prepayment penalties had no impact on our net interest margin in the second quarter of 2024, which is the same as in the prior quarter. Provision for credit losses totaled an expense of $3.2 million for the second quarter of 2024 compared to an expense of $1.6 million in the first quarter of 2024. The expense in the second quarter was primarily driven by charge-offs on the solar loan portfolio and increase in reserves on the solar loan portfolio, partially offset by improvements in macro-economic forecasts used in the CECL model. Non-interest income was $9.3 million for the second quarter of 2024, compared to $10.2 million in the first quarter of 2024. Excluding all non-core income adjustments, core non-interest income1 was $8.5 million for the second quarter of 2024, compared to $8.3 million in the first quarter of 2024. The increase was primarily related to higher commercial banking fees and increased fees from our treasury investment services, offset by modestly lower income from our trust business. Non-interest expense for the second quarter of 2024 was $39.5 million, an increase of $1.4 million from the first quarter of 2024. Core non-interest expense1 for the second quarter of 2024 was $39.5 million, an increase of $1.0 million from the first quarter of 2024. This was mainly driven by a $0.7 million increase in compensation and employee benefits expense due to select differential investments in employees, as well as higher data processing and personnel recruitment expense. 2

Our provision for income tax expense was $9.0 million for the second quarter of 2024, compared to $11.3 million for the first quarter of 2024. In the current quarter there were $0.5 million of discrete tax benefits resulting in an effective tax rate of 25.2%. In the prior quarter, the conclusion of a state and city tax examination resulted in an adjustment of $0.9 million additional tax expense. Excluding the discrete items and adjustment, our effective tax rate for the second quarter of 2024 was 26.6%, compared to 26.9% for the first quarter of 2024. Balance Sheet Quarterly Summary Total assets were $8.3 billion at June 30, 2024, compared to $8.1 billion at March 31, 2024, modestly growing our balance sheet within our target range. Notable changes within individual balance sheet line items include a $97.2 million decrease in cash and cash equivalents, a $152.8 million increase in securities, and a $49.0 million increase in net loans receivable. Additionally, deposits excluding Brokered CDs increased by $152.0 million while Brokered CDs decreased $8.8 million, and other borrowings decreased by $60.0 million. Our off-balance sheet deposits increased by $607.0 million, or 133%, to $1.1 billion. Total net loans receivable, at June 30, 2024 were $4.4 billion, an increase of $49.0 million, or 1.1% for the quarter. The increase in loans is primarily driven by a $55.1 million increase in multifamily loans, a $23.9 million increase in commercial real estate loans, offset by a $1.7 million decrease in commercial and industrial loans, a $12.9 million decrease in consumer solar loans, and a $14.7 million decrease in residential loans. During the quarter, criticized or classified loans decreased $6.4 million, largely related to a $9.5 million paydown on a classified commercial and industrial loan, and an upgrade of $3.7 million of commercial and industrial loans based on improvement in performance. This was offset by downgrades of small business loans totaling $6.1 million, and a $2.1 million increase in residential and consumer criticized and classified loans. Total deposits at June 30, 2024 were $7.4 billion, an increase of $143.2 million, or 2.0%, during the quarter. Total deposits excluding Brokered CDs increased by $152.0 million to $7.3 billion, or a 2.1% increase. Including accounts currently held off-balance sheet, deposits held by politically active customers, such as campaigns, PACs, advocacy-based organizations, and state and national party committees were $1.7 billion as of June 30, 2024, an increase of $292.3 million during this quarter, of which a substantial portion were moved off-balance sheet. Non-interest-bearing deposits represented 46% of average total deposits and 47% of ending total deposits for the quarter, excluding Brokered CDs, contributing to an average cost of total deposits of 155 basis points. Super-core deposits2 totaled approximately $4.2 billion, had a weighted average life of 17 years, and comprised 58% of total deposits, excluding Brokered CDs. Total uninsured deposits were $4.5 billion, comprising 60% of total deposits. Nonperforming assets totaled $35.7 million, or 0.43% of period-end total assets at June 30, 2024, an increase of $1.7 million, compared with $34.0 million, or 0.42% on a linked quarter basis. The increase in nonperforming assets was primarily driven by a $3.0 million increase in residential real estate nonaccrual loans and a $0.5 million increase in commercial and industrial nonaccrual loans, offset by a $1.1 million decrease in consumer solar nonaccrual loans and $0.8 million of commercial and industrial loan charge-offs. During the quarter, the allowance for credit losses on loans decreased $1.0 million to $63.4 million. The ratio of allowance to total loans was 1.42%, a decrease of 4 basis points from 1.46% in the first quarter of 2024. The decrease was primarily the result of a commercial and industrial loan charge-off that was previously fully reserved for. 3 2 Refer to Terminology on page 5 for definitions of certain terms used in this release.

Stockholders’ equity at June 30, 2024 was $646.1 million, an increase of $29.2 million during the quarter.
