### Footnotes:

(1) The reporting person disclaims beneficial ownership of these securities except to the extent of his pecuniary interest therein.

(2) The call options expiring on June 18, 2026 were acquired in a series of transactions. These options were all immediately exercisable from the applicable date of purchase until their expiration.

(3) The price reported in Column 8 is a weighted average price. These shares were sold in multiple transactions at prices ranging from $2.05 to $2.20, inclusive. The reporting person undertakes to provide to NextNav Inc., any security holder of NextNav Inc., or the staff of the Securities and Exchange Commission, upon request, full information regarding the number of shares sold at each separate price within the ranges set forth in footnote (3) to this Form 4.

**Remarks:**
The exit box is checked because, after the sale of the 600,000 shares of the common stock of NextNav Inc. (the "Common Stock") and the sale of the call options representing 400,000 shares of Common Stock reflected in this Form 4, the reporting person is no longer a 10% owner.

**Signature:** /s/ Joseph Samberg  
**Date:** 2025-11-17
