Old Second Bancorp Investment Narrative Recap

To own Old Second Bancorp, you need to be comfortable with a bank that leans into higher yielding specialty and powersports lending while trying to keep credit losses in check. The Q2 revenue beat supports the idea that this model can still produce solid top line results, even as net interest income growth expectations slow and deposit competition remains significant.

The key near term factor remains how credit costs trend from here, particularly around commercial real estate and powersports loans. If net charge offs linger at elevated levels, that could chip away at earnings quality. The Q2 result does not remove that risk, but it also does not appear to worsen it in a material way.

The most relevant development alongside this quarter is the ongoing focus on an asset sensitive balance sheet and tax equivalent net interest margin above 5%, supported by total deposit costs around 1.00%. The Q2 revenue outcome shows Old Second Bancorp is still relying on that spread driven engine, with specialty and powersports portfolios feeding into higher yielding assets.

This same mix links directly back to both the main catalyst and the main risk. Higher APR specialty and powersports loans and fee streams help support resilience in net interest income and overall revenue. At the same time, those portfolios require tight credit discipline. Elevated net charge offs or further stress in office related commercial real estate would quickly test how durable this model is over the next few quarters.

Old Second Bancorp Analyst Expectations In Context

Old Second Bancorp sits in front of a fairly specific analyst script. Revenue is assumed to rise by about 1.5% per year over the next three years, with profit margins moving from 27.1% today to 38.8% in that same period. Earnings are projected to reach US$138.4 million by around 2029 compared with US$92.4 million today, with earnings per share of US$2.65 on those figures.

The jump from US$92.4 million in earnings today to US$138.4 million represents an increase of about US$46 million on analyst numbers. That path also assumes the share count shrinks by roughly 3.41% a year over the next three years, which would help earnings per share even if profit growth is modest. The Q2 revenue beat fits into this story as one more data point that aligns with a gradual revenue trend rather than a rapid reset higher or lower.

On valuation, the analyst framework points to Old Second Bancorp trading on a P/E multiple of 11.4x by 2029, based on the projected US$138.4 million in earnings. That multiple would be lower than the current 13.6x and roughly in line with the present US banks sector P/E of 11.4x. The discount rate used in the Simply Wall St model is 7.24%, while the scenario that ties revenue, earnings and valuation together in the consensus view references a similar 7.2% cost of equity when discounting back to today.

Price targets cluster in a relatively tight range. The consensus sits at US$28.0 per share, with the most optimistic analyst at US$30.0 and the most cautious at US$25.0. Against a recent share price of US$24.66 as of early October 2026, that central target is about 11.9% higher. Those numbers imply that much of the perceived opportunity rests on Old Second Bancorp hitting the forecast margin expansion and earnings trajectory rather than on a sharp rerating of the earnings multiple.

Old Second Bancorp's narrative projects US$357.0 million revenue and US$138.4 million earnings by 2029, based on analyst estimates. This requires 1.5% yearly revenue growth and an earnings increase of about US$46.0 million from US$92.4 million today.

Uncover why Old Second Bancorp's fair value indicates a 13% potential upside to its current price, which could narrow quickly.
