Why are they buying?

AI · discretionary · catalyst credible · documented

Insiders stepped in to purchase millions of dollars of stock following a steep decline of over 22% triggered by a critical short-seller report from Muddy Waters Research.

The heavy insider buying occurred across late April and early May 2026, directly after public reports alleged improper client operations and caused significant share price volatility.
