BALANCE SHEET

Total assets were $949.4 million as of June 30, 2025, representing an increase of $96.4 million, or 11.3%, from June 30, 2024.

• Cash and cash equivalents increased to $55.2 million from $44.1 million, a $11.1 million, or 25.2%, year over year as a result of the cash raised in the reorganization and stock offering.
• Net loans were $751.2 million, representing an increase of $69.3 million or 10.2% from the prior year as demand for new originations continued. The main driver of the new growth was in multi-family, residential real estate and commercial real estate loans, which increased $41.8 million, $18.8 million and $16.9 million, respectively, partially offset by a decline in the construction portfolio of $5.5 million.
• Investment securities totaled $104.5 million, representing an increase of $17.9 million or 20.6% from the prior year due to purchases of U.S. treasuries and government agency securities.
• Deposits totaled $679.2 million, representing an increase of $43.8 million, or 6.9% from the prior year. The increase in deposits was a result of growth in customer deposits, primarily money market and certificate of deposit accounts, which increased by $35.1 million and $21.0 million, respectively, partially offset by decreases in savings and demand deposit accounts, which decreased by $8.2 million and $4.1 million, respectively.
• Shareholders' equity was $115.4 million, representing an increase of $35.1 million from $80.3 million, or 43.7% from the prior year. The increase was driven by net stock offering proceeds, which totaled $37.8 million partially offset by the one-time contribution to the Charitable Foundation and $3.3 million for the purchase of 334,633 shares of common stock by the employee stock ownership plan ("ESOP") in the offering.

NET INTEREST INCOME

• The increase in interest income during the year ended June 30, 2025 was primarily attributable to an increase in average earning assets of $100.0 million, and an increase of 38 basis points in average asset yields.
