BY does not currently have enough recent insider (Form 4) trading activity to compute a convergence signal against its 13F institutional flows.
13F data as of 2026-06-30 quarterly filings. Note: many large institutions file close to the 45-day post-quarter deadline, so early-quarter flow figures can shift substantially as more filings arrive.

Byline Bancorp released its Q2 2026 earnings press release on July 23, 2026, and also posted a related slide deck on its website for a public conference call scheduled for July 24. This 8-K simply "furnishes" those materials—meaning they are not officially "filed" under securities laws.
