(the “Company”) is a wireless communications company focused on commercializing its spectrum assets to enable its targeted utility and critical infrastructure customers to deploy private broadband networks and on offering innovative broadband solutions to the same target customers. The Company is the largest holder of licensed spectrum in the 900 MHz band (896 - 901 / 935 - 940 MHz) with nationwide coverage throughout the contiguous United States, Hawaii, Alaska and Puerto Rico. On May 13, 2020, the Federal Communications Commission (the “FCC”) approved the Report and Order (the “Report and Order”) to modernize and realign the 900 MHz band to increase its usability and capacity by allowing it to be utilized for the deployment of broadband networks, technologies and solutions. The Report and Order was published in the Federal Register on July 16, 2020, and became effective on August 17, 2020. The Company is now engaged in qualifying for and securing broadband licenses from the FCC. At the same time, the Company is pursuing opportunities to monetize the broadband spectrum it secures to its targeted utility and critical infrastructure customers. The Company is also expanding the benefits and solutions it offers to the same targeted customers. As part of the Company’s solution expansion, the Company launched an integrated platform to accelerate the scale benefits of combining, or networking together, individual private broadband networks to enhance utilities’ resiliency, reach and collaboration. The first commercial service on the platform, CatalyX, includes public network roaming management solution along with secure, remote SIM provisioning. CatalyX is a turnkey connectivity management solution that helps utilities gain economic and operational benefits leveraging commercial broadband during their transition to private LTE (“PLTE”) networks, extending coverage into gap areas or providing back-up connectivity for private networks. The Company has successfully led and completed initiatives in 3GPP to secure enhancements to the US 900 MHz spectrum to benefit its customers, including the designation of a new band, both for LTE and 5G, as well as a transition to 5G, which received worldwide wireless industry support.</span></div><div style="margin-top:12pt;padding-left:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">Business Developments</span></div><div style="margin-top:12pt;padding-left:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:400;line-height:120%">TECO Agreement</span></div><div style="margin-top:12pt;padding-left:27pt"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">On November 22, 2023, the Company entered into an agreement with Tampa Electric Company (“TECO”) to provide TECO the use of the Company’s 900 MHz Broadband Spectrum for a term of 20 years throughout TECO’s service territory in West Central Florida (the “TECO Agreement”). The TECO Agreement also provides TECO an option to extend the agreement for two 10-year terms for additional payments. The TECO Agreement, which covers an approximately 2,000-square-mile service territory in West Central Florida, is expected to enable TECO to deploy a PLTE network providing critical broadband communications capabilities in support of its initiatives. The scheduled prepayments for the 20-year initial term of the TECO Agreement total $34.5 million, of which $6.9 million was received by the Company in December 2023.

The LCRA Agreement will support LCRA’s deployment of a PLTE network which will provide a host of capabilities including grid awareness, communications and operational intelligence that will enhance resilience and spur innovation at LCRA. The new licenses will enable LCRA to move from narrowband to next generation broadband and provide mission-critical data and voice services within LCRA and to more than 100 external customers such as electric cooperatives, schools and transit authorities across more than 73,000 square miles. Total consideration of $30.0 million is to be paid through fiscal year 2026 pursuant to the terms of the LCRA Agreement.
