Why are they buying?

AI · discretionary · catalyst credible · partial

Directors likely stepped in to acquire shares following recent price pullbacks and market reactions associated with earlier class action allegations and disclosures regarding procedural growth.

Multiple independent directors (David C. Habiger, Edward J. Ludwig, and Cheryl Pegus) acquired shares via open-market transactions on May 19 and May 20, 2026, totaling substantial investments shortly after recent corporate news and filing dates.
