Leverages existing LTE/5G networks to reduce TerraPoiNT CapEx deployment costs by approximately 75% ($250M reduction), with commensurate reduction in associated network OpEx costs. Accelerates deployment of near-nationwide (U.S.) and global resilient Positioning Navigation and Timing ("PNT") capability by integrating existing LTE/5G signals into NextNav's Terra PoiNT system. Expands the combined companies' leading IP portfolio, adding Nestwave's portfolio of geolocation patents to NextNav's 130+ existing patents. Improves NextNav's global market presence through Nestwave's long-standing French-based operations and EU relationships. N NEXTNAV 4#6Example of Potential Deployment: San Francisco Bay Area We can potentially dramatically reduce the deployment of Terra PoiNT beacons needed for resilient PNT by leveraging thousands of existing LTE/5G beacons.

NextNav believes full, resilient PNT services across the United States can now be achieved at a fraction of the prior estimated TerraPoiNT deployment costs. ~75% Expected Reduction in deployment costs domestically NextNav and Nestwave compatibility with LTE/5G systems lowers barriers to adoption by LTE/5G handsets and devices going forward, including through a software upgrade.
