1.The Spectrum Sale Agreements are subject to customary provisions regarding remedies for non-delivery, including termination rights and refund of amounts paid, if the Company fails to perform its other contractual obligations, including failure to deliver the relevant cleared 900 MHz Broadband Spectrum in accordance with the terms of the Agreements. A gain or loss on the sale of spectrum will be recognized for each county once we deliver the cleared 900 MHz Broadband Spectrum and the associated broadband licenses. See Note 5 Intangible Assets for further discussion on the sale of intangible assets.

The following table summarizes the Company’s short-term and long-term contingent liabilities related to spectrum sale agreements entered into in the non-ordinary course of business based on the estimated timing of license deliveries (in thousands) as of June 30, 2026 and March 31, 2026:

1.As these contracts were entered into outside the ordinary course of business, a reduction in the contingent liability and a gain or loss on the sale of spectrum will be recognized for each county once the Company delivers the 900 MHz Broadband Spectrum and the associated broadband licenses. See Note 5 Intangible Assets for further discussion on the sale of intangible assets.

In October 2022, the Company entered into an agreement with Xcel Energy providing Xcel Energy dedicated long-term usage of the Company’s 900 MHz Broadband Spectrum for a term of 20 years throughout Xcel Energy’s service territory in eight states (the “Xcel Energy Agreement”). In connection with the Xcel Energy Agreement, the Company entered into a guaranty agreement, under which the Company guaranteed the delivery of the relevant 900 MHz Broadband Spectrum and the associated broadband licenses in Xcel Energy’s service territory in eight states along with other commercial obligations. In the event of default or non-delivery of the specific territory’s 900 MHz Broadband Spectrum, the Company is required to refund payments it has received. In addition, to the extent the Company has performed any obligations, the Company’s liability and remaining obligations under the Xcel Energy Agreement will extend only to the remaining unperformed obligations. The Company recorded $76.0 million in deferred revenue in connection with the prepayments received as of June 30, 2026. The Company commenced delivery of the relevant cleared 900 MHz Broadband Spectrum and the associated broadband leases in the first

quarter of fiscal year 2024 and will continue through 2029. As of June 30, 2026, the maximum potential liability of future undiscounted payments under this agreement is approximately $66.5 million, reflecting a reduction in liability due to the obligations it has performed to date and revenue recognized.

In June 2025, the Company entered into an agreement to retune and acquire wireless licenses for approximately $28.0 million. In connection with this agreement, the Company entered into a guaranty agreement with the incumbent, under which the Company guaranteed the payment and performance of all obligations under the agreement to the incumbent in the event of default. In addition, to the extent the Company has performed any obligations under the agreement, the Company’s liability and remaining obligations will extend only to the remaining obligations. As of June 30, 2026, the maximum potential liability of future undiscounted payments under this agreement is approximately $13.1 million.

The Company sponsors defined contribution plans (the “Plans”) that cover our employees following the completion of an eligibility period. Under the Plans, participating employees may defer a portion of their pretax and post tax earnings up to the limits provided by local statutory requirements. The Company makes matching contributions, subject to limits of the base compensation that a participant contributes to the Plan. The Company records its portion of matching contributions within general and administrative expenses on the Company’s Consolidated Statement of Operations. The Company contributed $0.1 million and $0.2 million for the three months ended June 30, 2026 and 2025, respectively.
