Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions:

On November 24, 2009, Iowa Telecommunications Services, Inc. (the “Company”) issued a press release announcing that on November 23, 2009, it had entered into a definitive Agreement and Plan of Merger (the “Merger Agreement”) with Windstream Corporation, a Delaware corporation (“Windstream”), and Buffalo Merger Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of Windstream (“Newco”). The Merger Agreement provides that, upon the terms and subject to the conditions set forth in the Merger Agreement, the Company will merge with and into Newco, with Newco continuing as the surviving corporation (the “Merger”).

At the effective time and as a result of the Merger, each share of common stock, par value $0.01 per share, of the Company, issued and outstanding immediately prior to the effective time of the Merger will be converted into and become exchangeable for (i) shares of common stock of Windstream at a fixed exchange ratio of 0.804 and (ii) $7.90 in cash. In connection with the Merger, each outstanding stock option under the Company’s 2002 Stock Incentive Plan will be converted into the right to receive the merger consideration, less the exercise price of the stock option. Each share of restricted stock awarded under the Company’s 2005 Stock Incentive Plan will be treated the same as any other outstanding share of Company common stock, but the forfeiture provisions and other terms and conditions of the restricted stock will continue to apply to the merger consideration received for the restricted stock and the cash portion of the consideration will be retained by Windstream until the restrictions have lapsed.

Each of the Company and Windstream has made customary representations and warranties in the Merger Agreement. The Company has agreed to various covenants and agreements, including, among others, (i) to conduct its business in the ordinary course during the interim period between the execution of the Merger Agreement and consummation of the Merger, (ii) not to engage in certain kinds of transactions during such period, (iii) to convene and hold a meeting of its shareholders to consider and vote upon the Merger, (iv) that, subject to certain exceptions, the Board of Directors of the Company will recommend approval of the Merger Agreement by its shareholders, and (v) not to (a) solicit or knowingly facilitate inquiries or proposals relating to alternative business combination transactions or (b) subject to certain exceptions, engage in discussions or negotiations regarding, or provide any non-public information in connection with, alternative business combination transactions.

The Company intends to pay its regular quarterly dividend through the end of the quarter preceding the quarter in which the closing occurs, subject to approval of its Board of Directors and the limitations of its Credit Agreement. Subject to the same factors, the Company also intends to pay a prorated dividend for the portion of the quarter in which the closing occurs prior to the closing date, equal to a pro rata portion of the Company’s regular dividend for the period up to the closing date minus a pro rata portion of the Windstream dividend that holders will receive on the stock consideration in the merger for the same period.

Consummation of the Merger is subject to customary conditions, including the absence of a material adverse change relating to the Company and Windstream and approval of the Company’s shareholders. The approval of Windstream’s shareholders is not required, and there is no financing contingency in the Merger Agreement. The consummation of the Merger is also subject to the satisfaction of several regulatory approvals, including, without limitation: (i)

approval by the Federal Communications Commission; (ii) approval by the public utilities commissions, or similar governing bodies, of Iowa, Minnesota, Missouri and Nebraska; and (iii) the expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976.

The transaction is expected to close in the middle of 2010.

The Company or Windstream may terminate the Merger Agreement under certain circumstances, including, among other things, if the merger is not consummated by June 23, 2010 (subject to a three month extension to obtain outstanding regulatory approvals) or upon a material breach by the other party not curable within 30 days.

Windstream may also terminate the Merger Agreement in the event the Company’s Board of Directors withdraws or materially modifies or changes its recommendation of the merger in a manner adverse to Windstream. In connection with such a termination, or in the event the Merger Agreement is terminated in certain circumstances after the Company receives an acquisition proposal and within 12 months following such termination the Company enters into an agreement with a third party with respect to certain extraordinary transactions or certain extraordinary transactions are consummated, then, in either case, the Company must pay a fee of $25,000,000 to Windstream.

The foregoing description of the Merger Agreement and the transactions contemplated thereby is not complete and is subject to and qualified in its entirety by reference to the Merger Agreement, a copy of which is attached hereto as Exhibit 2.1 and the terms of which are incorporated herein by reference.

The Merger Agreement has been attached as an exhibit to provide investors and security holders with information regarding its terms. It is not intended to provide any other financial information about Windstream, the Company, or their respective subsidiaries and affiliates. The representations, warranties and covenants contained in the Merger Agreement were made only for purposes of that agreement and as of specific dates, are solely for the benefit of the parties to the Merger Agreement, may be subject to limitations agreed upon by the parties, including being qualified by confidential disclosures made for the purposes of allocating contractual risk between the parties to the Merger Agreement instead of establishing these matters as facts, and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors. Investors should not rely on the representations, warranties and covenants or any description thereof as characterizations of the actual state of facts or condition of Windstream, the Company, or any of their respective subsidiaries or affiliates. Moreover, information concerning the subject matter of the representations, warranties and covenants may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in public disclosures by Windstream or the Company.
