On February 6, 2026, the Board appointed (i) Jung Kyu Ham, (ii) Jung Soo Kim, and (iii) Gyeung Seog Cheon to the Board, effective February 9, 2026, to serve, until a successor has been duly elected and qualified or until an earlier death, resignation or removal, as directors of the Company. Messrs. Jung Kyu Ham, Jung Soo Kim and Gyeung Seog Cheon will serve as Class III, Class I, and Class II directors of the Company for a term expiring at the Company’s 2026, 2027, and 2028 annual meeting of stockholders, respectively. The Board also appointed Mr. Cheon to the audit committee of the Board.

For their services on the Board, the three newly appointed directors will receive an annual retainer of $20,000. The Company also intends to enter into an indemnification agreement with each of the three newly appointed directors in the same form as its standard form of indemnification agreement with its other directors and in the same form as previously filed with the Company’s Current Report on Form 8-K filed with the Securities and Exchange Commission on October 2, 2017.

Except as described above, the three newly appointed directors do not have any direct or indirect material interest in any transaction required to be disclosed pursuant to Item 404(a) of Regulation S-K. There are no arrangements or understandings between any of the three newly appointed directors and any other person pursuant to which they were elected as a director.
