Net Interest Income & Margin Net Interest Income Net Interest Margin (NIM) p$5.3 million or 2% fromprior quarter p $10.5 million or 4% from3Q 2025 p 10 bps from prior quarter p 16 bps from 3Q 2025 Net interest income and margin increased from the prior quarter due to the following factors: • Deposit pricing continued to improve, contributing to lower funding costs; average cost of deposits improved by 6 bps to 1.99%. • The tax equivalent yield on investment securities benefited from the sale of lower-yielding securities and reinvestment into higher- yielding securities, which improved the overall yield of the investment portfolio. • Tax equivalent yields on commercial loans increased 5 bps from the prior quarter, reflecting favorable loan repricing and improved commercial loan portfolio mix. Net interest income and margin also increased from a year ago due to the following factors: • Average NIDDA grew by $824 million while average interest bearing liabilities declined by $1.0 billion; average cost of deposits improved by 39 bps from a year ago. • Partially offset by lower tax-equivalent asset yields, as variable-rate loans and securities repriced downward faster than the benefit from lower funding costs and favorable funding mix dynamic due to lower SOFR/Fed funds basis.
