On July 18, 2014, Cbeyond, Inc. (the “Company”) completed its previously announced merger with Birch Communications, Inc., a Georgia corporation (“Birch”). Pursuant to the Agreement and Plan of Merger, dated as of April 19, 2014 (the “Merger Agreement”), by and among Birch, the Company, and Hawks Merger Sub, Inc., a Delaware corporation and wholly owned subsidiary of Birch (“Merger Sub”), Merger Sub merged with and into the Company (the “Merger”), with the Company continuing as the surviving corporation in the Merger. At the effective time of the Merger (the “Effective Time”), the Company became a wholly owned subsidiary of Birch.

At the Effective Time, in accordance with the terms of the Merger Agreement, each issued and outstanding share of common stock, par value $0.01 per share, of the Company (the “Shares”) was converted into the right to receive $10.00 per share in cash (the “Per Share Merger Consideration”), without interest, subject to any withholding of taxes required by applicable law.

Immediately prior to the Effective Time, in accordance with the terms of the Merger Agreement,

The merger consideration was funded by Birch from available cash and the proceeds of borrowings under its secured term loan and revolving credit facility (collectively, the “Credit Facilities”).

The description of the Merger and the Merger Agreement contained in this Current Report on Form 8-K does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Merger Agreement, which is incorporated herein by reference to the Company’s Current Report on Form 8-K dated April 21, 2014.

In connection with the completion of the Merger, on July 18, 2014, the Company notified the NASDAQ Global Select Market (“NASDAQ”) that each Share was converted into the right to receive the Per Share Merger Consideration, and requested that trading of the Shares on the NASDAQ be suspended and that NASDAQ file a notification of removal from listing on Form 25 with the Securities and Exchange Commission (the “SEC”). As of the close of business on July 18, 2014, the Shares, which traded under the symbol “CBEY,” ceased trading on, and are being delisted from, NASDAQ. In addition, the Company intends to file with the SEC a Certification on Form 15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), requesting the deregistration of the Company’s common stock under Section 12(g) of the Exchange Act and suspension of the Company’s reporting obligations under Sections 13(a) and 15(d) of the Exchange Act.
