Contingencies and Guaranty | Contingencies and Guaranty Contingent Liabilities Spectrum Sale Agreements Entered into Prior to December 31, 2025 As a result of the Company’s business strategy evolution and the introduction of the Company’s new brand and visual identity in the fourth quarter of fiscal 2026, as described in Note 2 Summary of Significant Accounting Policies, sales agreements entered into in subsequent to this shift are considered completed in the ordinary course of business and are included in Note 3 Revenue.

1.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. Guaranties 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 March 31, 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 March 31, 2026, the maximum potential liability of future undiscounted payments under this agreement is approximately $67.4 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 March 31, 2026, the maximum potential liability of future undiscounted payments under this agreement is approximately $18.2 million. Defined Contribution Plan - Employer Contributions 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 $0.4 million and $0.5 million for the years ended March 31, 2026 and 2025, respectively. Litigation In addition to commitments and obligations in the ordinary course of business as reflected in the lease footnote above, the Company may be subject, from time to time, to various claims and pending and potential legal actions arising out of the normal conduct of its business. The Company assesses contingencies to determine the degree of probability and range of possible loss for potential accrual in its financial statements. Because litigation is inherently unpredictable and unfavorable resolutions could occur, assessing litigation contingencies is highly subjective and requires judgments about future events. When evaluating contingencies, the Company may be unable to provide a meaningful estimate due to a number of factors, including the procedural status of the matter in question, the presence of complex or novel legal theories and/or the ongoing discovery and development of information important to the matters. In addition, damage amounts claimed in litigation against it may be unsupported, exaggerated or unrelated to possible outcomes, and as such are not meaningful indicators of its potential liability. The Company regularly reviews contingencies to determine the adequacy of its accruals and related disclosures. During the period presented, the Company has not recorded any accrual for loss contingencies associated with any claims or legal proceedings; determined that an unfavorable outcome is probable or reasonably possible; or determined that the amount or range of any possible loss is reasonably estimable. However, the outcome of legal proceedings and claims brought against the Company is subject to significant uncertainty. Therefore, although management considers the likelihood of a material adverse outcome to be remote, if one or more of these legal matters were resolved against the Company in a reporting period, the Company’s consolidated financial statements for that reporting period could be materially adversely affected.
