Accounting Policies [Abstract]
BASIS OF PRESENTATION	NOTE 1: BASIS OF PRESENTATION The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information. As permitted under those rules, certain footnotes or other financial information that are normally required by GAAP can be condensed or omitted. These financial statements have been prepared on the same basis as our annual consolidated financial statements and, in the opinion of management, reflect all normal recurring adjustments, which are necessary for the fair statement of our financial information. As such, the information included in this Quarterly Report on Form 10-Q should be read in conjunction with the Company’s audited consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the year ended December 31, 2025 (“2025 Form 10-K”) as filed with the SEC on February 24, 2026. Operating results for interim periods are not necessarily indicative of the results that may be expected for any subsequent quarter or for the fiscal year ending December 31, 2026. All intercompany balances and transactions have been eliminated in consolidation. Continuing operations consist of the Broadband business. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. The Company’s significant accounting policies are described in Note 2 to its audited Consolidated Financial Statements included in the 2025 Form 10-K. There have been no significant changes to these policies during the six months ended July 3, 2026. As previously reported, on December 8, 2025, the Company entered into a Put Option Agreement to sell its Video business to Leone Media Inc. (d/b/a MediaKind) (the “Buyer”) for a purchase price of $145 million in cash. On March 20, 2026, the Buyer and the Company executed the Asset Purchase Agreement (the "APA"). On June 16, 2026, the Company completed the sale of its Video business to the Buyer pursuant to the APA. Proceeds from the sale were $137.9 million paid at closing, subject to final adjustments under the terms of the APA. Following the disposition, Harmonic operates as a pure-play broadband company with a single reportable segment: Broadband. The results of the Video business are presented as discontinued operations in the accompanying unaudited condensed consolidated statement of operations for all periods presented. The assets and liabilities of the Video business have been reflected as assets and liabilities of discontinued operations in the accompanying unaudited condensed consolidated balance sheet for all prior periods presented. Unless otherwise noted, all amounts and disclosures included in these Notes to unaudited condensed consolidated financial statements reflect only our continuing operations. Refer to Note 3 for additional details on discontinued operations.
