TIMMINS MEGAN C. 4

What Happened
Megan C. Timmins, EVP, Chief Legal Officer and Secretary of Rockwell Medical, had 3,667 restricted stock units (RSUs) withheld to satisfy her estimated tax withholding obligation. The withholding was reported as a disposition at $0.90 per share, totaling $3,300. This was a routine tax-withholding transaction — not an open-market sale or a purchase.

Context
Withholding shares to cover taxes is a common administrative step when RSUs vest and does not necessarily indicate insider sentiment about the stock — it’s a substitute for a cash tax payment. This is not a market sale of shares; the shares were surrendered to satisfy withholding obligations.
