The following discussion and analysis provides information concerning our results of operations and financial condition. This discussion should be read in conjunction with our accompanying condensed consolidated financial statements and the notes thereto and the Prospectus.

Overview

GCI Liberty, Inc. ("GCI Liberty") consists of 100% of the outstanding equity interests in GCI, LLC, GCI Holdings, LLC ("GCI Holdings" or "GCI") and their subsidiaries (collectively, the "GCI Business"), and was formerly owned by Liberty Broadband, prior to the Separation (defined below).

GCI Liberty was formed in Nevada in December 2024 for the purpose of ultimately holding the GCI Business. On July 14, 2025, Liberty Broadband and its subsidiaries completed an internal reorganization in order for Liberty Broadband to transfer the GCI Business to GCI Liberty in exchange for GCI Liberty stock, including 10,000 shares of GCI Liberty non-voting preferred stock, and the assumption of liabilities related to the GCI Business by GCI Liberty. The internal reorganization resulted in GCI Liberty owning, directly or indirectly, GCI, LLC and the operations comprising, and the entities that conduct, the GCI Business. Following the internal reorganization, Liberty Broadband sold all of the non-voting preferred stock (the "Preferred Stock Sale") to third parties. The non-voting preferred stock is issued by GCI Liberty, has a 12% dividend rate and $1,000 per share liquidation price plus accrued and unpaid dividends. The mandatory redemption date is July 14, 2032. Following the Preferred Stock Sale, GCI Liberty effected a reclassification of GCI Liberty's existing common stock into a sufficient number of shares of Series A GCI Group common stock, Series B GCI Group common stock and Series C GCI Group common stock to complete the divestiture of GCI Liberty pursuant to the distribution (the "Distribution") by Liberty Broadband to the holders of record of Liberty Broadband common stock, as of the record date for the Distribution, of all the shares of GCI Group common stock held by Liberty Broadband immediately prior to the Distribution. The internal reorganization, the Preferred Stock Sale, the reclassification and the Distribution are collectively referred as the "Separation."

In connection with the Separation, the Company entered into certain agreements, including the separation and distribution agreement, a tax sharing agreement (the "Tax Sharing Agreement") and a tax receivables agreement (the "Tax Receivables Agreement"), pursuant to which, among other things, GCI Liberty and Liberty Broadband will indemnify each other against certain losses that may arise. The Tax Sharing Agreement governs the allocation of taxes, tax benefits, tax items and tax-related losses between Liberty Broadband and GCI Liberty, and the Tax Receivables Agreement governs the respective rights and obligations of Liberty Broadband and GCI Liberty with respect to certain tax matters. In addition, the Company entered into certain agreements, including a services agreement ("Services Agreement"), a facilities sharing agreement and an aircraft time sharing agreement, with Liberty Media Corporation ("Liberty Media") and/or its subsidiaries. Pursuant to the Services Agreement, Liberty Media will provide GCI Liberty with public company support services, including legal, tax, accounting, treasury, information technology, cybersecurity, internal auditing and investor relations services. GCI Liberty will reimburse Liberty Media for all out-of-pocket expenses incurred by Liberty Media in providing the services and will pay a services fee that will be subject to review and evaluation for reasonableness on a quarterly basis. The fees payable to Liberty Media for the first year of the Services Agreement are not expected to exceed approximately $5 million.

Update on Economic Conditions

GCI Holdings offers wireless and wireline telecommunication services, data services, and managed services to customers primarily throughout Alaska. Because of this geographic concentration, growth of GCI Holdings' business and operations depends upon economic conditions in Alaska. Unfavorable economic conditions, such as a recession or economic slowdown in the U.S., or inflation in the markets in which GCI operates, could negatively affect the affordability of and demand for GCI's products and services and its cost of doing business. In recent years, varying factors have contributed to significant volatility and disruption of financial markets and global supply chains. Additionally, the U.S. Federal Reserve began decreasing interest rates in 2024 after several years of higher rates, and while interest rates remained steady throughout most of 2025, the U.S. Federal Reserve further decreased rates in the second half of 2025. Mounting inflationary cost pressures and recessionary fears have negatively impacted the U.S. and global economy. Increased equipment costs, for example due to increased tariffs, could also impact GCI's results.

The Alaska economy is dependent upon the oil industry, state and federal spending, investment earnings and tourism. A decline in oil prices would put significant pressure on the Alaska state government budget. The Alaska state government has financial reserves that GCI Holdings believes may be able to help fund the state government for the next couple of years. The Alaska economy is subject to recessionary pressures as a result of the economic impacts of volatility in oil prices, inflation, and other causes that could result in a decrease in economic activity. While it is difficult for GCI Holdings to predict the future impact of a recession on its business, these conditions have had an adverse impact on its business and could adversely affect the affordability of and demand for some of its products and services and cause customers to shift to lower priced products and services or to delay or forgo purchases of its products and services. GCI Holdings' customers may not be able to obtain adequate access to credit, which could affect their ability to make timely payments to GCI Holdings and could lead to an increase in accounts receivable and bad debt expense. If Alaska experiences a recession or economic slowdown, it could negatively affect GCI Holdings' business including its financial position, results of operations, or liquidity, as well as its ability to service debt, pay other obligations and enhance shareholder returns.

In addition, during 2024 and continuing in 2025, GCI Holdings has experienced the impact of inflation-sensitive items, including upward pressure on the costs of materials, labor, and other items that are critical to GCI Holdings' business. GCI Holdings continues to monitor these impacts closely and, if costs continue to rise, GCI Holdings may be unable to recoup losses or offset diminished margins by passing these costs through to its customers or implementing offsetting cost reductions.

On July 4, 2025, the One Big Beautiful Bill Act ("OBBBA") was enacted into law. The accounting impacts from the law change were included in our third quarter results. The OBBBA did not have a material impact on income tax expense on our financial statements; however, we were able to defer cash taxes to future years as a result of the OBBBA.

On October 1, 2025, the federal government of the United States began a shut-down, which could affect the timeliness of government grant approvals and funding the Company receives.

Due to goodwill and intangible asset impairments recorded during the third quarter of 2025, the fair values of such intangible assets do not significantly exceed their carrying value. The Company will continue to monitor current business performance versus the current and updated long-term forecasts, among other relevant considerations, to determine if the carrying value of its assets (including goodwill and indefinite-lived intangible assets) is appropriate. Future outlook declines in revenue, cash flows, or other factors could result in a sustained decrease in fair value that may result in a determination that additional carrying value adjustments are required, which could be material.

Federal Universal Service Programs

Legal Challenges to the Constitutionality of the FCC Universal Service Support Programs.There have been a number of legal challenges to the constitutionality of the USF. The U.S. Courts of Appeals for the Sixth and Eleventh Circuits rejected such challenges in 2023, as did a panel of three judges in the Fifth Circuit. However, on July 24, 2024, the U.S. Court of Appeals for the Fifth Circuit sitting en banc ruled that the USF program is unconstitutional as currently administered, and remanded the case to the FCC. In its decision, the en banc Fifth Circuit concluded that there was an

I-20

impermissible public delegation of legislative authority to the FCC and an impermissible private delegation of authority from the FCC to the Universal Service Administrative Company, the private company responsible for USF administration. The Supreme Court granted petitions for certiorari from the Fifth Circuit's decision and heard the case on March 26, 2025. The Supreme Court issued a decision on June 27, 2025, reversing the Fifth Circuit and upholding the constitutionality of the USF contribution factor. There is continuing litigation, as petitioners have filed a new Petition for Review in the Fifth Circuit, on October 1, 2025, to challenge two statutory provisions that the Supreme Court did not have occasion to address, as well as to challenge the legality of the USAC, which administers that program for the FCC.

Pause in Federal Financial Assistance. On January 27, 2025, the Office of Management and Budget ("OMB") issued a memorandum directing a pause in federal financial assistance pending review for consistency with presidential executive actions. On January 28, 2025, OMB clarified that this only applied to programs affected by certain specified executive actions, which do not appear to include FCC universal service support programs. OMB subsequently withdrew the memorandum, which has also been subject to preliminary injunction by two federal district courts. However, if this or another pause were to extend to federal universal service support programs, or to other infrastructure grants that GCI Holdings receives, and such a pause were to become extended, it could have a material adverse effect on GCI Holdings' business and the Company's financial position, results of operations or liquidity.

RHC Program

GCI Holdings receives support from various USF programs including the RHC Program. The USF programs are subject to change by regulatory actions taken by the FCC, interpretations of or compliance with USF program rules, or legislative actions. The USF programs have also been subject to ongoing legal challenges, which could disrupt or eliminate the support GCI Holdings receives. Changes to any of the USF programs that GCI Holdings participates in could result in a material decrease in revenue and accounts receivable, which could have an adverse effect on GCI Holdings' business and the Company's financial position, results of operations or liquidity.

​

Revenue. Consolidated revenue decreased $5 million and increased $31 million for the three and nine months ended September 30, 2025, respectively, as compared to the same periods in 2024. The following table highlights selected key performance indicators used in evaluating the Company's business.

¹ A cable modem subscriber is defined by the purchase of cable modem service regardless of the level of service purchased. Small-to-Medium Business customers and promotional and suspended subscribers are included.

I-22

The components of revenue are as follows:

​

​

Consumer data revenuedecreased $2 million and $6 million for the three and nine months ended September 30, 2025, respectively, as compared to the same periods in 2024. The decrease for the three months ended September 30, 2025 was primarily driven by a decrease in the number of subscribers. The decrease for the nine months ended September 30, 2025 was primarily driven by a decrease in the number of subscribers, including the impact of the discontinuation of the Affordable Connectivity Program in 2024. Subscriber growth in rural areas has also been adversely impacted by an outage from a fiber break on a third-party network in which GCI Holdings uses capacity, however the network was restored during the three months ended September 30, 2025.

Consumer wireless revenueincreased $5 million and $11 million for the three and nine months ended September 30, 2025, respectively, as compared to the same periods in 2024. The increases were driven by an increase in wireless USF support for high cost areas.

Consumer other revenuedecreased $8 million and $11 million for the three and nine months ended September 30, 2025, respectively, as compared to the same periods in 2024. Consumer other revenue consists of consumer video and voice revenue. The decreases were primarily due to decreases in video subscribers. On May 5, 2025, GCI Holdings received regulatory approval to begin discontinuing video services. The Company began discontinuing service for remaining video customers after receiving the regulatory approval and as of September 30, 2025, the Company has exited the video business.

Business data revenueincreased $1 million and $42 million for the three and nine months ended September 30, 2025, respectively, as compared to the same periods in 2024,primarily due to service upgrades with existing health care and education customers.

Business wireless revenue decreased $1 million and $5 million for the three and nine months ended September 30, 2025, respectively, as compared to the same periods in 2024, primarily due to decreases in roaming revenue due to contractual changes.

Business other revenueremained flat for both the three and nine months ended September 30, 2025, as compared to the same periods in 2024. Business other revenue consists of business video and voice revenue. On May 5, 2025, GCI Holdings received regulatory approval to begin discontinuing video services. The Company began discontinuing service for remaining video customers after receiving the regulatory approval and as of September 30, 2025, the Company has exited the video business.

I-23

Operating expense

Consumer direct costsconsists of wireless handset inventory costs, video programming, wireless distribution costs, marketing and advertising expenses, bad debt expense, credit card and other transactional fees, and internal and external labor costs for managing relationships with consumer customers. Consumer direct costs decreased $6 million and $8 million for the three and nine months ended September 30, 2025, respectively, as compared to the same periods in 2024, due to decreases in video programming costs and distribution costs. The decreases in distribution costs were partially due to the temporary cost savings from a fiber break on a third party network in which GCI Holdings uses capacity, which was fully restored during the three months ended September 30, 2025.

Business direct costs consists of network distribution costs, largely to healthcare and education customers, as well as internal and external labor costs for managing relationships with business customers. Business direct costs decreased $1 million and $12 million for the three and nine months ended September 30, 2025, respectively, as compared to the same periods in 2024, due to decreases in distribution costs for health care and education customers, primarily related to temporary cost savings from a fiber break on a third party network in which GCI Holdings uses capacity, which was fully restored during the three months ended September 30, 2025.

Technology expenseconsists of field and technology operations costs incurred to manage the Company's network, including internal and external labor costs, software related costs, lease expenses, maintenance costs, as well as utility costs. Technology expenses increased $2 million and $5 million for the three and nine months ended September 30, 2025, respectively, as compared to the same periods in 2024, primarily due to increased maintenance and software costs.

Selling, general and administrative expenseconsists of corporate overhead costs largely comprised of internal and external labor costs, software costs, insurance expense, property taxes and professional service fees. Selling, general and administrative expense increased $8 million and $9 million for the three and nine months ended September 30, 2025, respectively, as compared to the same periods in 2024, primarily due to an increase in internal labor costs, including higher healthcare costs and higher accrued incentive payments, as well as increased corporate expenses related to amounts allocated pursuant to the Services Agreement, partially offset by a decrease in external labor costs.

Stock-based compensationdecreased $2 million for both of the three and nine months ended September 30, 2025, as compared to the same periods in 2024, primarily due to decreased grant activity prior to the Separation.

Depreciation and amortization remained relatively flat for the three and nine months ended September 30, 2025, as compared to the same periods in 2024.

Impairment of goodwill and intangible assets. During the nine months ended September 30, 2025, the Company recorded an impairment of goodwill and intangible assets of $525 million, consisting of a goodwill impairment of $108 million and an intangible asset impairment of $417 million. See note 4 to the accompanying notes to the condensed consolidated financial statements for additional information.

Operating Income (Loss). Consolidated operating loss increased $529 million and $487 million for the three and nine months ended September 30, 2025, respectively, as compared to the same periods in 2024. Operating loss was impacted by the above explanations.

I-24

Adjusted OIBDA. To provide investors with additional information regarding the Company's financial results, the Company also discloses Adjusted OIBDA, which is a non-GAAP financial measure. The Company defines Adjusted OIBDA as operating income (loss) plus depreciation and amortization, stock-based compensation, separately reported litigation settlements, restructuring, and impairment charges. The Company's chief operating decision maker and management team use this measure of performance in conjunction with other measures to evaluate its business decisions and allocate resources. The Company believes this is an important indicator of the operational strength and performance of its business by identifying those items that are not directly a reflection of business performance or indicative of ongoing business trends. In addition, this measure allows management to view operating results, perform analytical comparisons and identify strategies to improve performance. Accordingly, Adjusted OIBDA should be considered in addition to, but not as a substitute for, operating income, net income, cash flow provided by operating activities and other measures of financial performance prepared in accordance with U.S. generally accepted accounting principles. The following table provides a reconciliation of operating income (loss) to Adjusted OIBDA:

​

​

Consolidated Adjusted OIBDA decreased $8 million and increased $37 million during the three and nine months ended September 30, 2025, respectively, as compared to the same periods in 2024, due to the items discussed above.

Other Income and Expense

Components of Other income (expense) are presented in the table below.

​

​

Interest Expense. Interest expense remained relatively flat during the three and nine months ended September 30, 2025, as compared to the same periods in 2024.

Other, net.Other, net income was relatively flat during the three and nine months ended September 30, 2025, as compared to the same periods in 2024.

​

I-25

Income taxes. Earnings (losses) before income taxes and income tax (expense) benefit are as follows:

​

​

For the three months ended September 30, 2025, the income tax benefit differs from the U.S. statutory tax rate of 21% primarily due to state income taxes, mostly offset by an impairment of goodwill that is not deductible for tax purposes (see note 4 to the accompanying condensed consolidated financial statements). For the nine months ended September 30, 2025, the income tax benefit differs from the U.S. statutory rate of 21% primarily due to state income taxes, offset by an impairment of goodwill that is not deductible for tax purposes. For the three and nine months ended September 30, 2024, the income tax expense differs from the U.S. statutory tax rate of 21% primarily due to state income taxes.

Net earnings (loss). The Company had net losses of $387 million and net earnings of $21 million for the three months ended September 30, 2025 and 2024, respectively, and net losses of $325 million and net earnings of $54 million for the nine months ended September 30, 2025 and 2024, respectively. The change in net earnings (loss) was the result of the above-described fluctuations in our revenue, expenses, and other income and expenses.

Liquidity and Capital Resources

The following are potential sources of liquidity: available cash balances, cash generated by the operating activities of GCI Holdings, dividend and interest receipts, capital market transactions and debt (including borrowings under the Senior Credit Facility (as discussed in note 5 to the accompanying condensed consolidated financial statements)).

As of September 30, 2025, GCI Libertyhad a cash and cash equivalents balance of $124 million, which was substantially held in cash. When applicable, cash equivalents are invested in U.S. Treasury securities, other government securities or government guaranteed funds, AAA rated money market funds and other highly rated financial and corporate debt instruments.

​

The increase in cash provided by operating activities during the nine months ended September 30, 2025, as compared to the same period in 2024, was primarily driven by increased operating income (not factoring in the impairment) and timing differences in working capital accounts.

During the nine months ended September 30, 2025 and 2024, net cash flows used in investing activities were primarily related to capital expenditures, net of grant proceeds of $152 million and $143 million, respectively.

During the nine months ended September 30, 2025, net cash flows used in financing activities were primarily for net debt repayments of $87 million. During the nine months ended September 30, 2024, net cash flows used in financing activities were primarily for distributions to our former parent of $150 million, partially offset by net debt borrowings of $26 million.
