US telecoms provider Windstream has completed its previously announced USD1.1 billion merger with EarthLink, under which EarthLink shareholders receive 0.818 shares of Windstream common stock for each EarthLink share owned. No fractional shares of Windstream common stock were issued in the merger, and EarthLink stockholders will receive cash in lieu of any fractional shares. Both companies have satisfied all necessary customary closing conditions, including approval from shareholders of both Windstream and EarthLink. The combined company, which will retain the Windstream name, will be headquartered in Little Rock, Arkansas. Going forward, Windstream expects to achieve more than USD150 million in annual operating and capital expense synergies within 36 months of closing, an increase of USD25 million over its initial estimates.
