Accounting Changes and Error Corrections [Abstract]
Basis of Presentation	The accompanying condensed consolidated financial statements have been prepared in accordance with U.S. GAAP and with the instructions to the Quarterly Report on Form 10-Q and Article 10 of Regulation S-X for interim financial information. Accordingly, these financial statements do not include all of the information required by U.S. GAAP or SEC rules and regulations for complete financial statements. In the opinion of management, these financial statements reflect all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of the results of operations for the interim periods presented. The results of operations for any interim period are not necessarily indicative of results for the full year. These condensed consolidated financial statements should be read in conjunction with our consolidated financial statements and notes thereto included in our 2025 Form 10-K. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Estimates and assumptions are used in accounting for, among other things, the valuation of acquisition-related assets and liabilities, expected credit losses, programming and copyright expenses, deferred income taxes and related valuation allowances, loss contingencies, fair value measurements, impairment assessments, capitalization of internal costs associated with construction and installation activities, useful lives of long-lived assets and actuarial liabilities associated with certain benefit plans. Actual results could differ from those estimates. Certain prior-period amounts have been reclassified to conform to the current period presentation.
Liquidity	Liquidity Within 12 months from the issuance of these condensed consolidated financial statements, in October 2027, the $1,161 million principal amount of the 2027 LPR Senior Secured Notes will be due and payable by LCPR Senior Secured Financing. The proceeds of the 2027 LPR Senior Secured Notes were on-lent by LCPR Senior Secured Financing to certain entities within our Liberty Puerto Rico borrowing group, and the related senior secured proceeds loan will be due and payable at the same time that the 2027 LPR Senior Secured Notes become due and payable. The Company and our Liberty Puerto Rico borrowing group have respectively engaged advisors and are in discussions with the creditors of LCPR Senior Secured Financing and LCPR Loan Financing, and their respective advisors, in relation to managing the liabilities arising from the senior secured proceeds loans made by such entities to the Liberty Puerto Rico borrowing group, including the senior secured proceeds loan relating to the 2027 LPR Senior Secured Notes. As of November 4, 2026, these discussions have not resulted in an agreement between the parties, and the position of the relevant entities within the Liberty Puerto Rico borrowing group with respect to their debt and our position with respect to our equity interests in such entities remain uncertain. If an agreement is not reached before the maturity of the 2027 LPR Senior Secured Notes and the 2027 LPR Senior Secured Notes are not repaid in full, those creditors may seek to instruct LCPR Senior Secured Financing and LCPR Loan Financing to enforce their respective security interests over 100% of the equity in certain entities within the Liberty Puerto Rico borrowing group pursuant to the terms of the 2027 LPR Senior Secured Notes, the 2029 LPR Senior Secured Notes, the 2028 LPR Term Loan and the related senior secured proceeds loans, which would result in a loss of control and deconsolidation of those entities from our consolidated financial statements. The indebtedness of our other borrowing groups do not contain cross-default or cross-acceleration provisions to the indebtedness of the Liberty Puerto Rico borrowing group. As such, a default with respect to the 2027 LPR Senior Secured Notes, the 2029 LPR Senior Secured Notes, the 2028 LPR Term Loan and the related senior secured proceeds loans would not result in the acceleration of debt obligations of our other borrowing groups or Liberty Latin America’s ability to service its own obligations. Management has evaluated the potential impact on Liberty Latin America if an agreement with the applicable creditors is not reached and certain entities within the Liberty Puerto Rico borrowing group are deconsolidated. Based on the structure of our borrowing groups, the absence of any cross-default or cross-acceleration provisions between them, and the fact that the indebtedness of the Liberty Puerto Rico borrowing group is non-recourse to, and is not guaranteed by, the Company or our other borrowing groups, management does not expect such an outcome to impair Liberty Latin America’s ability to continue to operate or meet its obligations as they become due.
Accounting Changes and Recent Accounting Pronouncements	Accounting Changes ASU 2025-05 In July 2025, the FASB issued ASU No. 2025-05, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets (ASU 2025-05), which introduces a practical expedient for all entities and an accounting policy election for all entities, other than public business entities, that elect the practical expedient to simplify the estimation of expected credit losses for current accounts receivable and current contract assets. Entities electing the practical expedient can assume that current conditions as of the balance sheet date do not change for the remaining life of the asset. Entities must disclose whether they have elected to use the practical expedient and, if so, whether they have also applied the accounting policy election. ASU 2025-05 is effective for annual reporting periods beginning after December 15, 2025, and interim periods within those annual reporting periods, with early adoption permitted. This standard did not have a material impact on our consolidated financial statements. Recent Accounting Pronouncements ASU 2024-03 In November 2024, the FASB issued ASU No. 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses (ASU 2024-03), which requires more detailed disclosure in the notes to the financial statements about the types of expenses in commonly presented expense captions. In each annual and interim reporting period, entities are required to (i) disclose the amounts of (a) purchases of inventory, (b) employee compensation, (c) depreciation, and (d) intangible asset amortization included in each expense line item within continuing operations that is presented on the statement of operations, (ii) include certain amounts that are already required to be disclosed under current U.S. GAAP in the same disclosure as the other disaggregation requirements, (iii) disclose a qualitative description of the amounts remaining in each expense line item within continuing operations that are not separately quantified and (iv) disclose the total amount of selling expenses and, in annual reporting periods, an entity’s definition of selling expenses. In January 2025, the FASB issued ASU No. 2025-01, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date (ASU 2025-01). ASU 2024-03 is effective for annual reporting periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027, with early adoption permitted, as clarified in ASU 2025-01. We are currently evaluating the impact this standard will have on our consolidated financial statements. ASU 2025-06 In September 2025, the FASB issued ASU No. 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40) (ASU 2025-06), which provides accounting guidance to modernize the accounting for internal-use software costs. The amendments replace the prior stage-based model with a principles-based approach, removing all references to project stages and instead focusing on the two remaining criteria for capitalization, being i) management has authorized and committed to the funding for the software project and ii) it is probable a project will be completed and used as intended. Until both of these criteria are met, all software development costs should be expensed as incurred. ASU 2025-06 is effective for annual and interim periods beginning after December 15, 2027, with early adoption permitted. Entities may apply the amendments prospectively, retrospectively, or using a modified retrospective approach. We are currently evaluating the impact of ASU 2025-06 on our consolidated financial statements.
Recurring and Non-Recurring Fair Value Measurements	Recurring Fair Value Measurements Derivatives In order to manage our interest rate and foreign currency exchange risk, we have entered into various derivative instruments, as further described in note 5. We use the fair value method to account for most of our derivative instruments. The recurring fair value measurements of these derivative instruments are determined using discounted cash flow models. Most of the inputs to these discounted cash flow models consist of, or are derived from, observable Level 2 data for substantially the full term of these derivative instruments. This observable data mostly includes interest rate futures and swap rates, which are retrieved or derived from available market data. Although we may extrapolate or interpolate this data, we do not otherwise alter this data in performing our valuations. We incorporate a credit risk valuation adjustment in our fair value measurements to estimate the impact of both our own nonperformance risk and the nonperformance risk of our counterparties. Our and our counterparties’ credit spreads represent our most significant Level 3 inputs, and these inputs are used to derive the credit risk valuation adjustments with respect to these instruments. As we would not expect changes in our or our counterparties’ credit spreads to have a significant impact on the valuations of these instruments, we have determined that these valuations fall under Level 2 of the fair value hierarchy. Our credit risk valuation adjustments with respect to our interest rate derivative contracts are further explained in note 5. Non-recurring Fair Value Measurements Fair value measurements may also be used for purposes of non-recurring valuations performed in connection with our acquisition accounting and impairment assessments. During the three and nine months ended September 30, 2026, we did not perform any such non-recurring valuations. During the three and nine months ended September 30, 2025, we performed non-recurring valuations in connection with certain impairment assessments at Liberty Puerto Rico, as further discussed below.

Accounting Changes and Error Corrections [Abstract]

The accompanying condensed consolidated financial statements have been prepared in accordance with U.S. GAAP and with the instructions to the Quarterly Report on Form 10-Q and Article 10 of Regulation S-X for interim financial information. Accordingly, these financial statements do not include all of the information required by U.S. GAAP or SEC rules and regulations for complete financial statements. In the opinion of management, these financial statements reflect all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of the results of operations for the interim periods presented. The results of operations for any interim period are not necessarily indicative of results for the full year. These condensed consolidated financial statements should be read in conjunction with our consolidated financial statements and notes thereto included in our 2025 Form 10-K.

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Estimates and assumptions are used in accounting for, among other things, the valuation of acquisition-related assets and liabilities, expected credit losses, programming and copyright expenses, deferred income taxes and related valuation allowances, loss contingencies, fair value measurements, impairment assessments, capitalization of internal costs associated with construction and installation activities, useful lives of long-lived assets and actuarial liabilities associated with certain benefit plans. Actual results could differ from those estimates. Certain prior-period amounts have been reclassified to conform to the current period presentation.

Liquidity

Within 12 months from the issuance of these condensed consolidated financial statements, in October 2027, the $1,161 million principal amount of the 2027 LPR Senior Secured Notes will be due and payable by LCPR Senior Secured Financing. The proceeds of the 2027 LPR Senior Secured Notes were on-lent by LCPR Senior Secured Financing to certain entities within our Liberty Puerto Rico borrowing group, and the related senior secured proceeds loan will be due and payable at the same time that the 2027 LPR Senior Secured Notes become due and payable.

The Company and our Liberty Puerto Rico borrowing group have respectively engaged advisors and are in discussions with the creditors of LCPR Senior Secured Financing and LCPR Loan Financing, and their respective advisors, in relation to

managing the liabilities arising from the senior secured proceeds loans made by such entities to the Liberty Puerto Rico borrowing group, including the senior secured proceeds loan relating to the 2027 LPR Senior Secured Notes.

As of November 4, 2026, these discussions have not resulted in an agreement between the parties, and the position of the relevant entities within the Liberty Puerto Rico borrowing group with respect to their debt and our position with respect to our equity interests in such entities remain uncertain. If an agreement is not reached before the maturity of the 2027 LPR Senior Secured Notes and the 2027 LPR Senior Secured Notes are not repaid in full, those creditors may seek to instruct LCPR Senior Secured Financing and LCPR Loan Financing to enforce their respective security interests over 100% of the equity in certain entities within the Liberty Puerto Rico borrowing group pursuant to the terms of the 2027 LPR Senior Secured Notes, the 2029 LPR Senior Secured Notes, the 2028 LPR Term Loan and the related senior secured proceeds loans, which would result in a loss of control and deconsolidation of those entities from our consolidated financial statements.

The indebtedness of our other borrowing groups do not contain cross-default or cross-acceleration provisions to the indebtedness of the Liberty Puerto Rico borrowing group. As such, a default with respect to the 2027 LPR Senior Secured Notes, the 2029 LPR Senior Secured Notes, the 2028 LPR Term Loan and the related senior secured proceeds loans would not result in the acceleration of debt obligations of our other borrowing groups or Liberty Latin America’s ability to service its own obligations.

Management has evaluated the potential impact on Liberty Latin America if an agreement with the applicable creditors is not reached and certain entities within the Liberty Puerto Rico borrowing group are deconsolidated. Based on the structure of our borrowing groups, the absence of any cross-default or cross-acceleration provisions between them, and the fact that the indebtedness of the Liberty Puerto Rico borrowing group is non-recourse to, and is not guaranteed by, the Company or our other borrowing groups, management does not expect such an outcome to impair Liberty Latin America’s ability to continue to operate or meet its obligations as they become due.

Recurring and Non-Recurring Fair Value Measurements

Recurring Fair Value Measurements

Derivatives

In order to manage our interest rate and foreign currency exchange risk, we have entered into various derivative instruments, as further described in note 5. We use the fair value method to account for most of our derivative instruments. The recurring fair value measurements of these derivative instruments are determined using discounted cash flow models. Most of the inputs to these discounted cash flow models consist of, or are derived from, observable Level 2 data for substantially the full term of these derivative instruments. This observable data mostly includes interest rate futures and swap rates, which are retrieved or derived from available market data. Although we may extrapolate or interpolate this data, we do not otherwise alter this data in performing our valuations. We incorporate a credit risk valuation adjustment in our fair value measurements to estimate the impact of both our own nonperformance risk and the nonperformance risk of our counterparties. Our and our counterparties’ credit spreads represent our most significant Level 3 inputs, and these inputs are used to derive the credit risk valuation adjustments with respect to these instruments. As we would not expect changes in our or our counterparties’ credit spreads to have a significant impact on the valuations of these instruments, we have determined that these valuations fall under Level 2 of the fair value hierarchy. Our credit risk valuation adjustments with respect to our interest rate derivative contracts are further explained in note 5.

Non-recurring Fair Value Measurements

Fair value measurements may also be used for purposes of non-recurring valuations performed in connection with our acquisition accounting and impairment assessments. During the three and nine months ended September 30, 2026, we did not perform any such non-recurring valuations. During the three and nine months ended September 30, 2025, we performed non-recurring valuations in connection with certain impairment assessments at Liberty Puerto Rico, as further discussed below.
