    Balance sheet repositioning continues to drive improvements

    • Net interest margin continues to improve: Our net interest margin has continued to expand since the completion of our securities restructuring in October 2023, increasing over 100 basis points from our net interest margin of 1.21% for fiscal year 2023 to 2.39% for the quarter ended September 30, 2026. The more recent improvement was due mainly to the continued growth in our commercial loan portfolio, and, to a lesser extent, a reduction in borrowings.
