Glahn Ronald J 4

What Happened

• Ronald J. Glahn, SVP, Global Sales, Broadband at HARMONIC INC. (HLIT), had 3,750 restricted stock units (RSUs) convert into common shares on July 15, 2026 (listed as an exercise/conversion of a derivative, code M). The RSUs had an exercise/conversion price of $0.00 (i.e., they converted into shares without a cash exercise price).
• To cover tax withholding (code F), 1,031 of those shares were surrendered/withheld at a reported value of $12.99 per share, totaling $13,393. After withholding, the net shares retained by Glahn are 2,719 (3,750 converted − 1,031 withheld).

Context

• This was a standard RSU vesting/conversion with partial share withholding to satisfy tax obligations (a routine corporate compensation event), not an open-market purchase or sale of stock for investment purposes.
• Code notes: M = exercise/conversion of derivative (here, RSUs converting to shares); F = shares withheld to cover tax liabilities.
• Such inward conversions plus withholding are common and generally reflect compensation vesting rather than a directional insider market bet.
