Credit costs increased. The provision for credit losses was $7,500 in the quarter and $17,000 year-to-date, up from $2,500 and $4,900. Management links this mainly to elevated commercial and commercial real estate charge-offs, including about $6.8 million on two office relationships and $4.3 million on a warehouse and distribution borrower, plus roughly $8.3 million of powersport net charge-offs related to loans acquired in the Bancorp Financial transaction. The allowance for credit losses on loans stood at $70,380, with an additional $2.0 million for unfunded commitments.

Securities available-for-sale had fair value of $1,040,760 and gross unrealized losses of $49,083, and $663.7 million of securities were pledged. Stockholders’ equity increased to $902,811 as retained earnings grew despite $40,207 of treasury stock purchases and first-half dividends of $0.14 per share, with an additional $0.07 dividend declared for payment in August 2026.
Old Second Bancorp, Inc. reported strong results for the second quarter of 2026 with net income of $28.2 million, or $0.54 per diluted share, up from $25.6 million, or $0.48, in the first quarter.

Net interest income was $83.3 million, and the tax-equivalent net interest margin expanded nine basis points quarter over quarter to 5.23%, supported by a $60.6 million increase in loans to $5.25 billion.
Credit costs remained elevated but manageable. Net charge-offs were $9.2 million, largely from one downtown Chicago office credit and one commercial relationship, while nonperforming loans declined to 1.08% of total loans and the allowance for credit losses stood at 1.34% of loans. Noninterest income grew 5.0% to $13.3 million, and noninterest expense rose 2.1% to $51.3 million, producing an efficiency ratio of 51.72%.
Capital and per-share measures improved. Tangible book value per share increased to $14.77 despite the repurchase of 732,000 shares during the quarter. The tangible common equity to tangible assets ratio was 11.19%, while the common equity Tier 1 capital ratio was 13.28% and the Tier 1 leverage ratio 12.05%.
