Redwood City, California / Amsterdam, The Netherlands, September 21, 2016—Avast Software B.V. today announced that it has received written confirmation from the Committee on Foreign Investment in the United States (“CFIUS”) that CFIUS has completed its review of Avast’s proposed acquisition of AVG Technologies N.V. (NYSE: AVG) and determined that there are no unresolved national security concerns with respect to such acquisition. As previously announced, the United States Federal Trade Commission granted early termination of the waiting period applicable to the tender offer under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, Germany’s Federal Cartel Office granted clearance of the tender offer, and the required waiting period under the Austrian Cartel Act expired. As a result, all requisite antitrust and regulatory approvals in connection with Avast’s pending tender offer to purchase all of the outstanding ordinary shares of AVG for $25.00 in cash have been obtained.

Avast expects to complete the tender offer promptly following the expiration of the tender offer, which is currently scheduled to expire at 11:59 p.m., New York City time, on September 29, 2016, subject to the satisfaction of the other conditions set forth in the Offer to Purchase dated July 29, 2016, as amended.
