Cable One to Acquire Full Ownership of Mega Broadband

PHOENIX–(BUSINESS WIRE)–Cable One, Inc. (NYSE: CABO) (the “Company”) today announced it has entered into a definitive agreement to acquire all of the equity interests in Mega Broadband Investments Holdings LLC (“MBI”) that it does not already own. Full ownership of MBI will provide Cable One with a larger and more geographically diversified operating footprint in attractive markets and unlock efficiency opportunities from increased scale.

MBI is a leading provider of broadband services across the Southeast, Northwest and Mid-South United States and offers an extensive range of broadband, fiber connectivity, video and voice services for commercial and residential customers under the Vyve Broadband brand. MBI’s total revenues for the 12 months ended September 30, 2025 were approximately $310 million, with approximately 210,000 residential and business data customers across a network footprint with approximately 675,000 passings as of September 30, 2025.

“We are excited about the opportunity to acquire full ownership in MBI,” said Todd Koetje, Cable One Interim CEO and CFO. “Our strategic investment in MBI reflects our continuing commitment to provide rural America with reliable high-speed internet service. MBI has developed an excellent network in geographies that will be complementary to our existing footprint, enable us to expand our overall market footprint and enhance our long-term growth prospects. Their operating model and local-first focus is in line with our own operating philosophy and we look forward to combining with them and welcoming their exceptional team of associates to Cable One.”

Transaction Details

Cable One currently owns a 45% stake in MBI, and certain affiliates of GTCR LLC (the “GTCR Investors”) and MBI management own the balance of MBI. Under the terms of the transaction, the Company will pay a purchase price for the 55% of MBI that it does not already own calculated under a formula based on (i) a multiple of MBI’s adjusted earnings before interest, taxes, depreciation and amortization and (ii) MBI’s total net indebtedness. Based on currently available information, (i) the purchase price payable by the Company is expected to range between approximately $475 million and $495 million; and (ii) MBI’s total net indebtedness that will be outstanding at the time it becomes a wholly-owned subsidiary of the Company in the fourth quarter of 2026 is expected to be approximately $845 million to $895 million (in the form of term loans maturing in November 2027).

The GTCR Investors held a previously established put option to sell to the Company all the equity interests in MBI that the Company did not already own. On January 2, 2026, the GTCR Investors exercised this put option.

Cable One intends to finance the purchase price for the transaction with a combination of cash resources and indebtedness, which may include borrowings under the Company’s existing $1.25 billion revolving credit facility or new debt instruments.

The transaction is subject to customary closing conditions. The Company currently anticipates that the transaction will be completed on October 1, 2026.

Cravath, Swaine & Moore LLP acted as legal advisor to Cable One on the transaction.
