### CLAWBACK POLICY ACKNOWLEDGMENT
The Board of Directors (the “Board”) of GCT Semiconductor Holding, Inc. (the “Company”) has adopted the GCT Semiconductor Holding, Inc. Clawback Policy (the “Clawback Policy”) which is applicable to the Company’s Covered Executives. Any capitalized terms used in this acknowledgment that are not otherwise defined shall have the meaning ascribed to them in the Clawback Policy.

I, the undersigned, acknowledge that I have received a copy of the Clawback Policy, as it may be amended, restated, supplemented or modified from time to time, and that I have read it, understand it, and acknowledge that I am fully bound by, and subject to, all of the terms and conditions thereof.

In the event of any inconsistency between the terms of the Clawback Policy and the terms of any employment agreement to which I am a party, or the terms of any compensation plan, program, or arrangement under which Incentive Compensation (as defined in the Clawback Policy) has been granted, awarded, earned, or paid to me, whether or not deferred, the terms of the Clawback Policy shall govern.

If the Board determines that any Incentive Compensation I have received must be forfeited, repaid, or otherwise recovered by the Company, I shall promptly take whatever action is necessary to effectuate such forfeiture, repayment, or recovery.

I acknowledge that I am not entitled to indemnification in connection with the Company’s enforcement of the Clawback Policy.

I understand that any delay or failure by the Company to enforce any requirement contained in the Clawback Policy will not constitute a waiver of the Company’s right to do so in the future.
