Commitments and Contingencies Disclosure [Abstract]
Contingencies and Guaranty	Contingencies and Guaranty Contingent Liabilities SDG&E Refund Obligations In February 2021, the Company entered into the SDG&E Agreement with SDG&E, to sell 900 MHz Broadband Spectrum throughout SDG&E’s California service territory, including San Diego and Imperial Counties and portions of Orange County, for a total payment of $50.0 million. The total payment of $50.0 million is comprised of an initial payment of $20.0 million received in February 2021 and the remaining payments which are due as the Company delivers the relevant cleared 900 MHz Broadband Spectrum and the associated broadband licenses to SDG&E. As the Company is required to refund payments it has received from SDG&E in the event of termination or non-delivery of the specific county’s full 900 MHz Broadband Spectrum, it recorded the initial payments as contingent liability on the Company’s Consolidated Balance Sheets. 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 full cleared 900 MHz Broadband Spectrum and the associated broadband licenses to SDG&E. In September 2022, the Company transferred to SDG&E 1.4 x 1.4 cleared 900 MHz Broadband Spectrum and the associated broadband license related to Imperial County and received a milestone payment of $0.2 million. In September 2023, the Company transferred to SDG&E the San Diego County broadband license and received a milestone payment of $25.2 million net of delivery delay adjustments of $1.1 million. In December 2023, the Company transferred to SDG&E the remainder of the cleared 900 MHz Broadband Spectrum and the associated broadband license related to Imperial County and received a milestone payment of $0.2 million. This resulted in the recognition of a gain on the sale of spectrum and derecognition of the contingent liability associated with San Diego County and Imperial County. See Note 4 Intangible Assets for further discussion on the sale of intangible assets. Subsequent to the derecognition of the contingent liability related to the delivery of San Diego County and Imperial County licenses, the remaining contingent liability related to SDG&E of $1.0 million for Orange County is classified as a short-term liability due to the expected timing of delivery. LCRA Refund Obligation In April 2023, the Company entered into the LCRA Agreement for a total payment of $30.0 million, to be paid through fiscal year 2026 pursuant to the terms of the agreement. In December 2023, the Company received $15.0 million in milestone payments, of which $7.5 million was deposited in an escrow account. The remaining payments are due as the Company delivers the relevant cleared 900 MHz Broadband Spectrum and the associated broadband licenses to LCRA. As the Company is required to refund the deposit it has received from LCRA in the event of termination or non-delivery of the specific county’s full cleared 900 MHz Broadband Spectrum, it recorded the initial payments as contingent liability on the Company’s Consolidated Balance Sheets. 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 full cleared 900 MHz Broadband Spectrum and the associated broadband licenses to LCRA. See Note 3 Escrow Deposits for further discussion on the escrow deposit. In November 2024, the Company received the agreed upon narrowband spectrum licenses from LCRA with a fair value of $1.4 million, these licenses are recorded as contingent liability on the Company’s Consolidated Balance Sheets. As of December 31, 2024, the Company has classified $0.4 million and $14.6 million as short-term and long-term contingent liability, respectively, based on the estimated timing of license delivery associated with the LCRA Agreement. Oncor Refund Obligation In June 2024, the Company entered into the Oncor Agreement for a total payment of $102.5 million, to be paid through fiscal year 2026 pursuant to the terms of the agreement. In June 2024, the Company received an initial payment of $10.0 million with remaining payments due to the Company for each county, at closing. The timing and rights to milestone payments could vary as 900 MHz broadband licenses are granted by the FCC, broadband licenses are assigned to Oncor and incumbents are cleared by the Company. As the Company is required to refund the deposit it has received from Oncor in the event of termination or non-delivery of the specific county’s full cleared 900 MHz Broadband Spectrum, it recorded the initial payment as contingent liability on the Company’s Consolidated Balance Sheets. 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 full cleared 900 MHz Broadband Spectrum and the associated broadband licenses to Oncor. As of December 31, 2024, the Company has classified $4.0 million and $6.0 million as short-term and long-term contingent liability, respectively, based on the estimated timing of license delivery associated with the Oncor Agreement. Xcel Energy Guaranty In October 2022, the Company entered into an agreement with Xcel Energy Services Inc. (“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 $67.1 million in deferred revenue in connection with the prepayments received as of December 31, 2024. 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 December 31, 2024, the maximum potential liability of future undiscounted payments under this agreement is approximately $62.8 million, reflecting a reduction in liability due to the obligations it has performed to date. Litigation From time to time, the Company may be involved in litigation that arises from the ordinary operations of the business, such as contractual or employment disputes or other general actions. The Company is not involved in any material legal proceedings at this time. Macroeconomic Conditions Recent macroeconomic events, inflation and geopolitical matters, have increased operating costs or resulted in delays in customer contracting or impacted the availability of equipment necessary for the deployment of the Company’s target customers’ planned PLTE projects. The Company continues to closely monitor these risks. Although difficult to quantify, the Company believes the current macroeconomic environment, including inflation, may have an adverse effect on the Company’s target customers’ businesses, which may harm the Company’s commercialization efforts and negatively impact the Company’s revenues and liquidity. If the Company is not able to control its operating costs or if the Company’s commercialization efforts are slowed or negatively impacted, continued periods of high inflation could have a material adverse effect on the Company’s business, operating results and financial condition.
