(3)  Revenue Recognition

Contracts with Customers

The Company had receivables of $165 million and $154 million at September 30, 2026 and December 31, 2025, respectively, the long-term portion of which are included in Other assets, net. The Company had deferred revenue of $29 million and $31 million at September 30, 2026 and December 31, 2025, respectively. The receivables and deferred revenue are only from contracts with customers. GCI Holdings’ customers generally pay for services in advance of the performance obligation and therefore these prepayments are recorded as deferred revenue. The deferred revenue is recognized as revenue in the accompanying condensed consolidated statements of operations as the services are provided. Changes in the contract liability balance for the Company during the nine months ended September 30, 2026 were not materially impacted by other factors.

The Company expects to recognize revenue in the future related to performance obligations that are unsatisfied (or partially unsatisfied) of $131 million in the remainder of 2026, $304 million in 2027, $84 million in 2028, $72 million in 2029 and $102 million in 2030 and thereafter.

Revenue from contracts with customers, classified by customer type and significant service offerings, is as follows:

Government Assistance

​

In current and prior years, the Company has been awarded, as either the recipient or subrecipient, federal government grants to construct broadband infrastructure to unserved and underserved communities in rural Alaska. During the three months ended September 30, 2026 and 2025, the Company received zero and approximately $3 million, respectively, for grants awarded in current and prior years. During the nine months ended September 30, 2026 and 2025, the Company received approximately $5 million and $22 million, respectively, for grants awarded in current and prior years.

These grants are accounted for using a grant accounting model by analogy to International Accounting Standard 20, Accounting for Government Grants and Disclosure of Government Assistance. These grants were recorded as deferred revenue since the primary conditions for the receipt of the grant are the build out and operation of the broadband services over the established time frames, which range from 9 to 21 years for assets already placed in service and will be based on the property’s useful life for assets currently being constructed. During both the three and nine months ended September 30, 2026 and 2025, revenue recorded in the condensed consolidated financial statements was not material. Both

short-term and long-term deferred revenue have been recorded for the amounts of the grants received, with approximately $6 million recorded as short-term deferred revenue, as of both September 30, 2026 and December 31, 2025, and approximately $109 million and $108 million recorded as long-term deferred revenue, as of September 30, 2026 and December 31, 2025, respectively.
