Insights
Solid Q1 profitability and capital, offset by higher credit costs and nonperforming assets.
Old Second Bancorp generated Q1 2026 net income of $25.6M and diluted EPS of $0.48, down from $28.8M and $0.54 in Q4 2025. Core banking spreads were strong, with tax-equivalent net interest margin at 5.14% and an efficiency ratio of 52.40%, helped by a $2.7M decline in noninterest expense.
Credit costs moved higher: the $9.5M provision for credit losses exceeded the prior quarter’s $3.0M, and nonperforming assets increased to $77.0M, tied to a downtown Chicago office loan and another commercial relationship. However, allowance for credit losses covered 1.39% of total loans and 115.15% of nonaccrual loans, indicating meaningful reserves based on current disclosures.
Capital remained robust. Tangible common equity to tangible assets rose to 11.07%, even after $23.1M of stock repurchases, and Q1 return on average tangible common equity was 14.20%. These metrics suggest the balance sheet can absorb current credit issues while supporting shareholder returns, though future performance will depend on how problem credits and loan growth trends evolve in subsequent quarters.
