With Old Second Bancorp trading at $20.00, an intrinsic discount estimate of 58.84% and a price target of $23.40, an important question arises: is there real value here, or is the market already pricing in future growth?

Most Popular Narrative: 14.5% Undervalued

With Old Second Bancorp’s fair value narrative sitting at $23.40 against a last close of $20.00, the story centers on whether the current price reflects the earnings potential analysts have mapped out.

The recent Evergreen Bank acquisition is performing ahead of expectations, providing higher-than-expected profitability and a more favorable asset mix, which is expected to drive incremental revenue growth, strengthen net interest margin, and enhance ROA as integration is completed.

Read the complete narrative.

Curious how a single acquisition, steady revenue assumptions, margin expansion and a future earnings multiple combine into that $23.40 figure? The key inputs behind this narrative tie together loan growth, profitability targets and what analysts think is a reasonable valuation multiple on those future earnings, but the exact mix of assumptions is where the real story sits.

Result: Fair Value of $23.40 (UNDERVALUED)

Have a read of the narrative in full and understand what's behind the forecasts.

However, this hinges on Old Second managing its concentrated exposure to Illinois and keeping credit issues in commercial real estate from undermining the earnings story analysts are using.

Another way to look at Old Second’s valuation

The fair value story so far leans on analyst earnings forecasts and a target of $23.40, but the P/E picture pulls in a different direction. Old Second trades on 12x earnings, a touch richer than peers at 11.6x and the US Banks average at 11.5x, even though its fair ratio is 12.7x. That mix of slightly higher pricing today and a fair ratio above the current P/E suggests room for both disappointment and opportunity, depending on which number the market moves toward next.

Apple's near record highs, yet the AI crowd still writes it off as a laggard. I think they're misreading the strategy.
