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 t
