Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Other Information	Basis of Presentation and Other Information Shenandoah Telecommunications Company and its subsidiaries (collectively, “Shentel”, “we”, “our”, “us”, or the “Company”) provide broadband data, video and voice services to residential and commercial customers in portions of Virginia, West Virginia, Maryland, Pennsylvania and Kentucky, via fiber optic and hybrid fiber coaxial cable networks. We also lease dark fiber and provide Ethernet and Wavelength fiber optic services to enterprise and wholesale customers throughout the entirety of our service area. Shentel’s Broadband business also provides voice and DSL telephone services to customers in Virginia’s Shenandoah County and portions of adjacent counties as a Rural Local Exchange Carrier (“RLEC”). These integrated networks are connected by a fiber network. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X for interim financial information. All normal recurring adjustments considered necessary for a fair presentation have been included. Certain disclosures normally included in annual consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) have been omitted. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes contained in our Annual Report on Form 10-K for the year ended December 31, 2023. The preparation of the unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect reported amounts of assets, liabilities, revenues and expenses and related disclosures. On an on-going basis we evaluate significant estimates and assumptions, including, but not limited to, revenue recognition, stock-based compensation, estimated useful lives of assets, impairment of goodwill and indefinite-lived intangible assets, intangible assets subject to amortization, the computation of income taxes and the fair value of interest rate swaps. Future events and their effects cannot be predicted with certainty; accordingly, the Company’s accounting estimates require the exercise of judgment. The accounting estimates used in the preparation of the financial statements will change as new events occur, as more experience is acquired, as additional information is obtained, and as the Company’s operating environment changes. Management evaluates and updates assumptions and estimates on an ongoing basis. Actual results may differ from these estimates under different assumptions or conditions. Sale of Shentel’s Tower Portfolio On March 29, 2024, Shenandoah Mobile, LLC, a wholly-owned subsidiary of Shenandoah Telecommunications Company, completed the initial closing of its previously disclosed sale of substantially all of Shentel’s tower portfolio and operations (“Tower Portfolio”) to Vertical Bridge Holdco, LLC for $309.9 million (the “Tower Transaction”). The Company received $305.8 million, net of certain transaction costs at the time of the initial closing. At the initial close, the Company conveyed sites representing approximately 99.5% of the tower portfolio value. The Company expects to convey the remaining tower sites in the portfolio by the end of March 2025. The Tower Transaction was completed pursuant to the terms of a Purchase and Sale Agreement, dated February 29, 2024, as amended by Amendment No. 1 to the Purchase and Sale Agreement, dated March 29, 2024. The Tower Portfolio represented substantially all of the assets and operations in Shentel’s previously reported Tower Reporting Segment and the Tower Transaction represented a strategic shift in the Company’s business. Consequently, the Tower Portfolio has been reclassified as a discontinued operation. For all periods presented, the assets and liabilities that transferred in the Tower Transaction (the “disposal group”) are presented as held for sale in our unaudited condensed consolidated balance sheets, and operating results and cash flows related to the Tower Portfolio were reflected as a discontinued operations in our unaudited condensed consolidated statements of comprehensive income and unaudited condensed consolidated statements of cash flows. Refer to Note 14, Discontinued Operations for more information regarding the presentation of the disposal group in the Company’s financial statements. As a result of the sale of the Tower Portfolio, the Company has one reportable segment. Consequently, segment reporting previously disclosed is no longer applicable. Adoption of New Accounting Standards There have been no material developments related to recently issued accounting standards, including the expected dates of adoption and estimated effects on the Company’s unaudited condensed consolidated financial statements and note disclosures from those disclosed in the Company’s Annual Report on Form 10-K for its fiscal year ended December 31, 2023, that would be expected to impact the Company.
