Old Second Bancorp IncOSBC

Old Second Bancorp, Inc. (OSBC), the parent of Old Second National Bank, closed the books on Q1 2026 with $25.6m of net income attributable to the parent, $893.3m of shareholders’ equity, and $115.7m of cash and cash equivalents, all per the 10-Q filed 2026-05-08. The diluted EPS clocked in at $0.48 on 53.3m weighted average shares outstanding, while operating cash flow for the quarter was $36.9m and the bank tucked away $769k in property, plant, and equipment-barely enough to buy a single branch sign.

Old Second National Bank is an Illinois-chartered commercial bank whose product pages promise “equipment financing for construction, farming, and manufacturing,” Zelle transfers, and a suite of mobile apps, all wrapped in FDIC insurance. The bank also publishes its Community Reinvestment Act public file, which is the regulatory equivalent of leaving the kitchen light on so the neighbours know you’re still solvent.

On 2026-07-21 the company filed an 8-K disclosing the appointment of William L. Kubik as Lead Independent Director, a move that arrived alongside a 2026-07-08 8-K announcing the retirement of a director and a 2026-07-22 8-K detailing routine third-quarter board and committee fees. The human machinery of governance keeps turning even when the balance-sheet machinery is humming at a modest tempo.

Old Second’s own press release from October 2025 trumpets the “completion of systems and brand conversion” of Evergreen Bank Group, which the bank says expanded its Chicagoland footprint to 55 locations. The image on the release shows a smiling customer at a counter, which is the banking equivalent of a stock photograph that has been airbrushed to remove the stress lines.

If you need a chart of the company’s share price action, the evidence set provided does not include a price series or a chart route; therefore no levels or commentary on performance are supplied here. The renderer will decide whether to add a price rail once a valid source is supplied. (source: SEC EDGAR index, https://www.sec.gov/edgar/browse/?CIK=357173)

What changed this week: the bank filed routine governance updates and director fee disclosures, while the 10-Q confirms the financial shape of the business remains solid but plain vanilla. What remains unproven: whether the expanded branch network will translate into materially higher net interest margin, fee income, or operating leverage over the next year, given the thin cash position and modest capital ratios. Evidence that would deepen the file includes an updated efficiency ratio, loan growth decomposition, and a tangible book-value reconciliation-none of which are supplied in the current evidence set.
