ManTech International (NASDAQ:MANT) Chairman and CEO George J. Pedersen will ring the closing bell at NASDAQ on April 10 in celebration of the tenth anniversary of the company’s listing on the exchange.

ManTech International listed on NASDAQ on February 6, 2002. Its 2001 revenue was $430 million. In the ten years since listing, ManTech’s revenue has grown to nearly $3 billion, shareholder equity has grown from $23 million to $1.1 billion, and it has made 20 strategic acquisitions.

Most recently, ManTech announced that it had acquired Evolvent Technologies, which marked its entry in the healthcare IT market, and HBGary, which will allow it to offer integrated products and services for cyber security to both government and commercial customers.

“We have enjoyed great success and tremendous growth since listing on NASDAQ, and our shareholders have been a big part of that,” said Mr. Pedersen. “They not only share profits through the dividends we pay, but they play a role in helping to secure the nation. We are looking forward to celebrating our success with our partners at NASDAQ, who also share in our success.”
