Glahn Ronald J 4

What Happened

• Ronald J. Glahn, SVP, Global Sales, Broadband at Harmonic Inc. (HLIT), converted 3,750 restricted stock units (RSUs) into 3,750 shares on April 15, 2026 (transaction code M). There was no cash exercise price ($0.00 per share).
• To cover tax withholding (transaction code F), 1,042 of those shares were surrendered/withheld at a reported value of $9.88 per share, totaling $10,295. Net new shares received by Glahn = 3,750 - 1,042 = 2,708.

Context

• This was a conversion of RSUs (award vesting), not an open-market purchase or deliberate sale; withholding shares to satisfy tax obligations is a routine administrative step, not necessarily a market sentiment signal.
• Transaction codes: M = exercise/conversion of a derivative (RSU conversion to shares); F = payment of exercise price or tax liability (shares withheld).
