Exhibit (a)(5)(B)

Optimum Subsidiary Announces Preliminary Results of Tender Offer
for Shares of Optimum’s Class A Common Stock

NEW YORK (July 1, 2026) — CSC Investments II LLC, a Delaware limited liability company (“CSC Investments II”), and a wholly owned subsidiary of Optimum Communications, Inc. (NYSE: OPTU) (“Optimum”), today announced the preliminary results of its tender offer, which expired at 5:00 p.m., New York City time, on June 30, 2026.

Based on the preliminary count by Equiniti Trust Company, LLC, the depositary for the tender offer (the “Depositary”), a total of approximately 254,956,213 shares of Optimum’s Class A Common Stock, par value $0.01 per share (each share of Optimum’s Class A Common Stock, a “Share,” and collectively, the “Shares”), were validly tendered and not validly withdrawn at the purchase price of $2.50 per Share, which includes 20,062,734 Shares that were tendered through notice of guaranteed delivery.

In accordance with the terms and conditions of the tender offer and based on the preliminary count by the Depositary, CSC Investments II expects to accept for purchase an aggregate of 120,000,000 Shares at a purchase price of $2.50 per Share, for an aggregate cost of approximately $300,000,000, excluding fees and expenses relating to the tender offer. Because the tender offer was oversubscribed, CSC Investments II expects to accept the Shares on a pro rata basis, except for tenders of “odd lots,” which will be accepted in full, and conditional tenders that will automatically be regarded as withdrawn because the condition was not satisfied. CSC Investments II has been informed by the Depositary that the preliminary proration factor for the tender offer is approximately 47.1%. The Shares expected to be accepted for purchase represent approximately 42.5% of the Shares that were issued and outstanding as of June 30, 2026.

The number of Shares expected to be purchased in the tender offer and proration factor are preliminary and subject to change. The preliminary information contained in this press release is subject to confirmation by the Depositary and is based on the assumption that all Shares tendered through notice of guaranteed delivery will be delivered within the one business day delivery period. The final number of Shares to be purchased in the tender offer will be announced following the expiration of the guaranteed delivery period and the completion by the Depositary of the confirmation process. Payment for the Shares accepted for purchase pursuant to the tender offer, and the return of all other Shares tendered and not purchased, will occur promptly thereafter. Payment for Shares will be made in cash, subject to applicable withholding and without interest.
