Barker Robert 4

What Happened
Robert Barker, a Class II director of GCT Semiconductor Holding, Inc. (GCTS), received an award of 24,122 restricted stock units (RSUs) on March 31, 2026. The RSUs are recorded at $0.00 acquisition price (a grant) and were calculated by dividing a $27,500 target amount by the fair market value of $1.14 per share on March 31, 2026, then rounding down. Based on the $1.14 FMV, the notional value of the granted shares is roughly $27.5K. The RSUs are subject to vesting and will be payable in common stock per the reporting person’s deferral election.

Context
RSUs are a form of compensation that convert to actual shares only upon vesting and settlement; they are not an open-market purchase and do not immediately increase tradable float. This filing documents a grant (compensation) rather than a purchase or sale. The Form 4 was filed two days after the transaction date (filed 2026-04-02 for a 2026-03-31 report), which is generally within the normal two-business-day reporting window.
