NextNav Says On Oct 9, Subsidiary Amended Agreement With AT&T For Pinnacle Network; Agreement Term Extended To October 28, 2028

On October 9, 2025, NextNav LLC, a wholly-owned subsidiary of NextNav Inc. (the "Company"), entered into an amendment (the "Amendment") to the Equipment, Network Colocation and Installation Agreement with AT&T Services, Inc. ("AT&T"), dated October 7, 2019 (the "Agreement"), relating to our Pinnacle network operations. The Agreement was previously filed as Exhibit 10.11 to the Company's Registration Statement on Form S-4 filed on August 25, 2021.

As previously disclosed, our Pinnacle network is primarily operated in partnership with AT&T as part of its FirstNet® initiative. Our Pinnacle system is primarily used for public safety applications, including enhanced E911 to devices operating on all the national cellular networks. The Pinnacle altitude stations are co-located at AT&T wireless sites pursuant to the Agreement and take advantage of the power systems, including battery backup and generators, at the AT&T sites. We monitor the Pinnacle network health through our network operations center ("NOC"). Connectivity among the Pinnacle altitude stations, our cloud service platform, and our NOC are enabled through wireless connections, currently provided by AT&T. We are not required to use AT&T wireless sites for network expansion and may establish new service areas through independently acquired site leases or with other partners.

The Amendment materially extends the term of this Agreement. Prior to the Amendment, the Agreement was scheduled to expire on October 7, 2026. Pursuant to the Amendment, the term of the Agreement has been extended for approximately two years and will now expire on October 28, 2028. Other than the extension of the term, the Amendment does not modify any operational, financial or other terms of the Agreement.
