Cable One provided service to approximately 1.1 million residential and business customers, of which approximately 1,062,000 subscribed to data services, 202,000 subscribed to video services and 136,000 subscribed to voice services, as of September 30, 2022. On October 1, 2020, the Company contributed its Anniston, Alabama system (the “Anniston System”) to Hargray in exchange for an approximately 15% equity interest in Hargray on a fully diluted basis. On May 3, 2021, the Company acquired the remaining approximately 85% equity interest in Hargray that it did not already own for an approximately $2.0 billion cash purchase price, which implied a $2.2 billion total enterprise value for Hargray on a cash-free and debt-free basis. The all-cash transaction was funded through a combination of cash on hand and proceeds from new indebtedness. Refer to note 2 for further details on this transaction. On December 30, 2021, the Company acquired certain assets and assumed certain liabilities from Cable America Missouri, LLC, a data, video and voice services provider in central Missouri ("CableAmerica"), for $113.1 million in cash on a debt-free basis. The all-cash transaction was financed with cash on hand. Refer to note 2 for further details on this transaction. On January 1, 2022, the Company closed a joint venture transaction in which the Company contributed certain fiber operations (including certain fiber assets of Hargray and a majority of the operations of Delta Communications, L.L.C. ("Clearwave")) (the "Clearwave Fiber Contribution") and certain unaffiliated third-party investors contributed cash to a newly formed entity, Clearwave Fiber LLC ("Clearwave Fiber"). The operations contributed by the Company generated approximately 3% of Cable One's consolidated revenues for the three months ended December 31, 2021. The Company's approximately 58% investment in Clearwave Fiber was valued at $440.0 million as of the closing date. Clearwave Fiber is intended to accelerate deployment of fiber internet to residents and businesses in existing markets and near-adjacent areas, as well as to provide connectivity to unserved and underserved areas in such markets via fiber-to-the-premises service. Clearwave Fiber is reported on Cable One’s balance sheet under the equity method of accounting, with the proportionate share of its net income (loss) each period reflected within Cable One's operating results on a one quarter lag.
