Byline Bancorp (BY) just rolled out a fresh share repurchase program, with board approval to buy back up to 2.25 million shares, roughly 5% of the float, running through the end of 2026.

The buyback comes after a strong run, with a 14.1% 1 month share price return and a 5 year total shareholder return of 113.1%, suggesting momentum is still quietly building around a $30.51 share price.

If this capital return story has your attention, it could be a good moment to widen the lens and explore fast growing stocks with high insider ownership.

With the stock trading below its analyst price target and screening as undervalued on intrinsic metrics, the new buyback raises a key question for investors: is this a genuine mispricing, or is the market already discounting future growth?

Most Popular Narrative Narrative: 10.3% Undervalued

Byline Bancorp's most followed narrative pegs fair value at 34 dollars per share, slightly above the 30.51 dollars last close and quietly supportive of the new buyback.

The analysts have a consensus price target of $32.2 for Byline Bancorp based on their expectations of its future earnings growth, profit margins and other risk factors. In order for you to agree with the analyst's consensus, you would need to believe that by 2028, revenues will be $532.2 million, earnings will come to $141.9 million, and it would be trading on a PE ratio of 13.9x, assuming you use a discount rate of 6.9%.

Curious what justifies paying a richer multiple for a regional bank with only moderate growth? The narrative leans on specific revenue, margin and earnings paths. Want to see exactly how those moving parts stack up and support that higher fair value?

Result: Fair Value of $34 (UNDERVALUED)

However, tighter regulation as Byline approaches the 10 billion dollar asset threshold, and any worsening in credit quality, could quickly challenge this upbeat margin story.
