MBI Term Loan Exchange Offer — Expiration and Results

On June 24, 2026, Cable One, Inc. (the “Company”) announced that, as of 5:00 p.m., New York City time, on June 23, 2026, the designated exchange agent for the Company’s previously announced offer (the “MBI Term Loan Exchange Offer”) to lenders (the “MBI Lenders”) of the senior secured term loans (the “MBI Term Loans”) outstanding under that certain Credit Agreement, dated as of November 12, 2020 (as amended, amended and restated, supplemented or otherwise modified from time to time), among Mega Broadband Investments Holdings LLC (“MBI”), as borrower, the lenders from time to time party thereto and Truist Bank, as administrative agent, had received irrevocable lender acceptances from MBI Lenders holding approximately 34.0% of all outstanding MBI Term Loans.

The Company reserves the right, in its sole discretion, not to consummate the MBI Term Loan Exchange Offer for any reason.

The MBI Term Loan Exchange Offer was made pursuant to the offer materials distributed to eligible MBI Lenders, a copy of which was filed as Exhibit 99.1 to the Company’s Current Report on Form 8-K filed on June 22, 2026 and is incorporated herein by reference.

This Current Report on Form 8-K does not constitute an offer to purchase or a solicitation of an offer to sell any securities, nor shall there be any sale of any securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction.

Cautionary Statement Regarding Forward-Looking Statements

This current report may contain “forward-looking statements” that involve risks and uncertainties. These statements can be identified by the fact that they do not relate strictly to historical or current facts, but rather are based on current expectations, estimates, assumptions and projections about the Company’s industry, business, strategy, technologies, acquisitions and strategic investments, market expansion plans, dividend policy, capital allocation, financing strategy, the purchase price payable pursuant to the put option associated with the remaining equity interests in MBI which was exercised on January 2, 2026 (such purchase price, the “Put Price”) and the anticipated timeline to consummate such transaction, the Company’s ability and sources of capital to fund the Put Price, MBI’s future indebtedness and the Company’s financial results and financial condition. Forward-looking statements often include words such as “will,” “should,” “anticipates,” “estimates,” “expects,” “projects,” “intends,” “plans,” “believes” and words and terms of similar substance in connection with discussions of future operating or financial performance. As with any projection or forecast, forward-looking statements are inherently susceptible to uncertainty and changes in circumstances. The Company’s actual results may vary materially from those expressed or implied in its forward-looking statements. Accordingly, undue reliance should not be placed on any forward-looking statement made by the Company or on its behalf. Important factors that could cause the Company’s actual results to differ materially from those in its forward-looking statements include government regulation, economic, strategic, political and social conditions and the following factors, which are discussed in the Company’s latest Annual Report on Form 10-K as filed with the Securities and Exchange Commission (the “SEC”):

·	rising levels of competition from historical and new entrants in the Company’s markets;

·	recent and future changes in technology, and the Company’s ability to develop, deploy and operate new technologies, service offerings and customer service platforms;

·	risks associated with the Company’s use of artificial intelligence;

·	the Company’s ability to grow its residential data and business data revenues and customer base;

·	increases in programming costs and retransmission fees;

·	the Company’s ability to obtain hardware, software and operational support from vendors, including the potential impacts of changes in trade policy and tariffs;

·	risks relating to existing or future acquisitions and strategic investments by the Company, including risks associated with the exercise of the put option associated with the remaining equity interests in MBI and the acquisition and integration of MBI;

·	the integrity and security of the Company’s network and information systems;

·	the impact of possible security breaches and other disruptions, including cyber-attacks;

·	the Company’s failure to obtain necessary intellectual and proprietary rights to operate its business and the risk of intellectual property claims and litigation against the Company;

·	the Company’s ability to maintain effective internal control over financial reporting and disclosure controls and procedures;

·	impairments of intangible assets and goodwill;

·	legislative or regulatory efforts to impose new requirements on the Company’s data services;

·	additional regulation of the Company’s video and voice services or changes to government subsidy programs;

·	the Company’s ability to renew cable system franchises;

·	increases in pole attachment costs;

·	changes in local governmental franchising authority and broadcast carriage regulations;

·	the potential adverse effect of the Company’s level of indebtedness on its business, financial condition or results of operations and cash flows;

·	the restrictions the terms of the Company’s indebtedness place on its business and corporate actions;

·	the possibility that interest rates will rise, causing the Company’s obligations to service its variable rate indebtedness to increase significantly;

·	risks associated with the Company’s indebtedness, including the Company’s ability to pay dividends on, make distributions in respect of, repurchase or redeem, capital stock;

·	provisions in the Company’s charter, by-laws and Delaware law that could discourage takeovers and limit the judicial forum for certain disputes;

·	adverse economic conditions, labor shortages, supply chain disruptions, changes in rates of inflation and the level of move activity in the housing sector;

·	pandemics, epidemics or disease outbreaks, such as the COVID-19 pandemic, have, and may in the future, disrupt the Company’s business and operations, which could materially affect the Company’s business, financial condition, results of operations and cash flows;

·	lower demand for the Company’s residential data and business data products;

·	fluctuations and/or declines in the Company’s stock price;

·	dilution from equity awards, convertible indebtedness and potential future convertible debt and stock issuances;

·	damage to the Company’s reputation or brand image;

·	the Company’s ability to retain key employees (whom the Company refers to as associates);

·	the Company’s ability to successfully transition to its new Chief Executive Officer;

·	the Company’s ability to incur future indebtedness;

·	provisions in the Company’s charter that could limit the liabilities for directors; and

·	the other risks and uncertainties detailed from time to time in the Company’s filings with the SEC, including but not limited to those described under “Risk Factors” in its latest Annual Report on Form 10-K and in its subsequent filings with the SEC.

Any forward-looking statements made by the Company in this current report speak only as of the date on which they are made. The Company is under no obligation, and expressly disclaims any obligation, except as required by law, to update or alter its forward-looking statements, whether as a result of new information, subsequent events or otherwise.
