Mr. Moorthy holds a B.S. in Physics from the University of Bombay, a B.S. in Electrical Engineering from the University of Washington, and an MBA, Marketing, from National University.

For his service on the Board, Mr. Moorthy will be compensated pursuant to the Company’s Independent Director Compensation Policy (the “Policy”), which is attached as Exhibit 10.36 to the Company’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2025 filed with the Commission on May 8, 2025 (File No. 001-39135).
