Black Box Corporation (NASDAQ:BBOX) today announced that on April 30, 2006 it completed its previously-announced acquisition of the USA Commercial and Government and Canadian Operations of NextiraOne, LLC, a company owned by Platinum Equity, LLC. These operations service commercial and various government agency clients and represent approximately $270 million to $280 million of projected annualized voice services revenues. Black Box and NextiraOne will begin the integration process, including the immediate re-branding of the NextiraOne business as Black Box. The combined Black Box and NextiraOne entity will continue to fully support installed and new voice technology requirements for all NextiraOne clients. Black Box also will continue to be a Strategic Authorized National Nortel Elite Business Partner for all of Nortel's products and services throughout the USA and Canada. The transaction is being accounted for as a purchase.

The actual equity book value adjustment will be confirmed post-closing at which time the final purchase price will be determined. The purchase price was paid in cash.
