Black Box Announces Status of Independent Review of Stock Option Grant Practices and Expected Restatement of Previously Issued Financial Statements.

PITTSBURGH -- Black Box Corporation (NASDAQ:BBOX) reported today on the status of the independent review of past stock option grant practices currently being undertaken under the direction of the Audit Committee (the "Audit Committee") of the Board of Directors of Black Box Corporation (the "Company"), with the assistance of outside legal counsel, and the expected restatement of previously issued financial statements.

As previously announced, the Audit Committee is conducting an independent review of the Company's historical stock option grant practices and related accounting for stock option grants during the period from 1992 to the present. On February 1, 2007, the Company announced that, while the review of option grant practices was continuing, it believed that it would need to record additional non-cash charges for stock-based compensation expense relating to certain stock option grants and, accordingly, cautioned investors about relying on its historical financial statements until the Company could determine with certainty whether a restatement would be required and, if so, the extent of any such restatement and the periods affected.

Although the Audit Committee has not yet completed its review, the Audit Committee has concluded that the exercise price of certain stock option grants differed from the fair market value of the underlying shares on the appropriate measurement date. Although the review of option practices is ongoing, Company management and the Audit Committee currently expect that the Company's additional non-cash, pre-tax charges for stock-based compensation expense relating to certain stock option grants will approximate $63 million for the period under review. In addition, the Company and the Audit Committee have now concluded that the Company will need to restate its previously issued financial statements contained in reports previously filed by the Company with the Securities and Exchange Commission (the "SEC"). The Company continues to expect that any such restatement will not have a material impact on its earnings for the fiscal year ending March 31, 2007.

Accordingly, on March 19, 2007, Company management and the Audit Committee concluded that the Company's previously issued financial statements and other historical financial information and related disclosures for the period under review, including applicable reports of its current or former independent registered public accounting firms and related press releases, should not be relied upon.

The Company will prepare and file with the SEC, as soon as practical after completion of the ongoing review of option practices, any necessary reports or amendments to previous SEC filings as well as its Form 10-Q for the fiscal quarter ended December 30, 2006.

Company management and the Audit Committee have discussed the matters in this release with BDO Seidman, LLP, the Company's independent registered public accounting firm.
