(d) Appointment of Lisa Hook as Director

On February 24, 2026, the Board of Directors (the "Board") of NextNav Inc. (the "Company") increased the size of the Board from nine (9) directors to ten (10) directors and appointed Lisa Hook as a director to fill the resulting vacancy. Her term will expire at the Company's 2026 Annual Meeting of Stockholders (the "Annual Meeting") and will continue until her successor has been elected and qualified, subject, however, to earlier death, resignation, retirement, disqualification, or removal. She will stand for reelection at the Annual Meeting. Ms. Hook was appointed to serve as the Board's Lead Independent Director and as a member of the Board's Technology and National Defense and Compensation and Human Capital Committees.

For her service as Lead Independent Director, Ms. Hook will receive cash and equity compensation as follows: an initial equity grant of approximately $75,000, an annual equity grant of approximately $175,000, and an annual cash retainer of $80,000. Ms. Hook will also receive cash compensation for her service on Board committees, consistent with that provided to all non-employee directors.

The Company will enter into an indemnity agreement with Ms. Hook in connection with her appointment to the Board. The indemnity agreement will be substantially the same form as the indemnity agreement for the other directors of the Company, which was filed as Exhibit 10.2 to the Company's Current Report on Form 8-K filed with the U.S. Securities and Exchange Commission on October 28, 2021.

No arrangement or understanding exists between Ms. Hook and any other person pursuant to which she was appointed as a director. There are no transactions in which she has an interest that would require disclosure under Item 404(a) of Regulation S-K.
