Earnings More Than Double

Net Interest Margin Expands to 3.67%
Net interest margin increased 64 basis points year-over-year to 3.67%, as the yield on interest-earning assets rose 38 basis points and the cost of interest-bearing liabilities fell 31 basis points.
-
Balance Sheet Transformed by WFB Deal
Total assets grew 36% to $3.86 billion, total loans increased 41% to $3.06 billion, and total deposits rose 37% to $3.21 billion, primarily due to the January 1 acquisition of Wichita Falls Bancshares.
-
Credit Quality Deteriorates Slightly
Nonperforming loans increased to 0.63% of total loans from 0.43% at year-end 2025, driven by downgrades of a $6.6 million commercial real estate relationship and a $1.6 million construction loan. The allowance for credit losses to total loans decreased to 1.18% from 1.26% a year ago.
Analysis · ISTR · Finance
The second quarter reveals just how transformative the Wichita Falls Bancshares acquisition, which closed on January 1, has been for Investar. Net income available to common shareholders more than doubled to $8.9 million, fueled by a 70% jump in net interest income as the loan book swelled to $3.1 billion. Driving that income surge, the net interest margin expanded 64 basis points to 3.67%, reflecting higher-yielding acquired loans and lower funding costs. Credit quality, however, warrants attention — nonperforming loans rose to 0.63% of total loans, up from 0.43% at year-end, and the allowance coverage ratio dipped to 1.18%. While the balance sheet is significantly larger and more profitable, integration costs and asset quality trends will be key going forward.
