Optimum Communications, Inc.

Item 2.02 Results of Operations and Financial Condition. The information appearing below under Item 4.02 regarding certain previously reported financial information of Optimum Communications, Inc. (the "Company") for the fiscal year ended December 31, 2025, and the fiscal quarters and year-to-date periods ended September 30, 2025, March 31, 2026, and June 30, 2026, is incorporated herein by reference. The information appearing below under Item 4.02(a) refers to certain financial statements that the Company intends to restate. The Company identified that it inadvertently failed to recognize non-cash deferred tax benefits associated with two previous non-cash impairment charges of its indefinite-lived cable franchise rights during the periods described above. The restatement will not affect the Company's previously reported cash balances, revenues, capital expenditures, cash flows, EBITDA or loss before income taxes.

Item 4.02(a). Non-Reliance on Previously Issued Financial Statements or a Related Audit Report or Completed Interim Review On September 16, 2026, the Audit Committee of the Board of Directors (the “Audit Committee”) of the Company, in consultation with management, concluded that certain previously issued consolidated financial statements of the Company (and related earnings releases, shareholder communications, investor presentations or other materials describing relevant portions of such financial statements) should no longer be relied upon because of errors in such financial statements related to understatements of deferred tax benefits and overstatements of a related deferred tax liability. The audited consolidated financial statements as of and for the fiscal year ended December 31, 2025, contained within the Annual Report on Form 10-K for such year (and the associated audit report of the Company’s independent registered public accounting firm) and the unaudited consolidated financial statements contained within the Quarterly Reports on Form 10-Q for the interim periods ended September 30, 2025, March 31, 2026, and June 30, 2026, were impacted by these errors. Accordingly, the Company intends to restate these financial statements by amending its Annual Report on Form 10-K for the year ended December 31, 2025, along with the applicable quarterly reports on Form 10-Q (the “Restated Filings”), as soon as reasonably practicable. Additionally, because the errors also impact the consolidated financial statements of the Company’s wholly-owned subsidiary, CSC Holdings, LLC, the Company intends to restate those consolidated financial statements for the corresponding periods. Subsequent to the issuance of the Company’s consolidated financial statements as of and for the three and six months ended June 30, 2026, the Company identified that it inadvertently failed to recognize non-cash deferred tax benefits associated with two previous non-cash impairment charges of its indefinite-lived cable franchise rights during the periods described above. Such errors resulted in understatements of deferred income tax benefits and overstatements of the related deferred tax liability, which accordingly also impacted total liabilities, accumulated deficit, total stockholders’ deficiency and net loss. This identification of errors is preliminary, unaudited and may be subject to change (including the potential identification of additional errors) as we complete our procedures and prepare the Restated Filings. The Audit Committee, along with management, discussed with KPMG LLP, the Company’s independent registered public accounting firm, the matters disclosed in this filing pursuant to this Item 4.02(a). Summary of Impacts The restatements are expected to reduce our previously reported net losses by correcting understatements of deferred tax benefits and overstatements of a related deferred tax liability of (i) approximately $430 million for the three and nine-month periods ended September 30, 2025, and for the year ended December 31, 2025, and (ii) approximately $720 million for the quarter ended March 31, 2026, and the six-month period ended June 30, 2026. These restatements will have corresponding impacts to total liabilities, accumulated deficit, and total stockholders’ deficiency; however, will not affect the Company's previously reported cash balances, revenues, capital expenditures, cash flows, EBITDA or loss before income taxes. Controls and Procedures Management is assessing the effect of the restatements on the Company’s internal control over financial reporting and disclosure controls and procedures and expects to report in its amended filings that a material weakness in its internal control over financial reporting related to accounting for income taxes existed during the affected periods. Accordingly, the Audit Committee concluded that management’s report on internal control over financial reporting as of December 31, 2025, and KPMG LLP’s opinion on the effectiveness of the Company’s internal control over financial reporting as of December 31, 2025, should no longer be relied upon.
