This Amendment No. 4 (“Amendment  No. 4”) to Schedule 13D relates to the common stock, $0.0001 par value per share (the “Common Stock”), of NextNav Inc. (the “Issuer”), and amends and supplements the initial statement on Schedule 13D filed on November 8, 2021, as amended and supplemented by Amendment No. 1 to Schedule 13D filed on January 30, 2023, Amendment No. 2 to Schedule 13D filed on March 14, 2024 and Amendment No. 3 to Schedule 13D filed on November 14, 2024 (as previously amended, the “Prior Schedule 13D”). Except as specifically provided herein, this Amendment No. 4 does not modify any of the information previously reported in the Prior Schedule 13D. Capitalized terms used but not defined in this Amendment No. 4 shall have the same meanings ascribed to them in the Prior Scheduled 13D.

This Amendment No. 4 is being filed to reflect the update to the aggregate percentage of Common Stock owned by the Reporting Persons due to the transactions described in Item 5(c), resulting in a decrease of over one percent (1%) in the aggregate percentage ownership reported by CCIV, CCEI IV and Mr. Fleming.  Additionally, as a result of the transactions reported herein, as of December 5, 2024, the Reporting Persons ceased to be the beneficial owner of more than five percent of the Common Stock.
