(Attach Extra Sheets if Needed)
Black Box Corporation (the “Company”) did not file its Quarterly Report on Form 10-Q for the fiscal
quarter ended June 30, 2007
(“Form 10-Q”) by August 9, 2007, the required filing date.
As previously announced, the Audit Committee (the “Audit Committee”) of the Board of Directors of
the Company, with the assistance of outside legal counsel, is conducting an independent review of
the Company’s historical stock option grant practices and related accounting for stock option
grants. As a result of the review, and due to the allocation of Company personnel and resources to
such review, the Company is in the process of completing the audit of its financial statements for
the fiscal year ended March 31, 2007 and, therefore, has not filed its Annual Report on Form 10-K
for the fiscal year ended March 31, 2007 (“Form 10-K”).
At the present time, the Company plans to file the Form 10-K on or about August 13, 2007. As
previously announced, on August 14, 2007, the Company will release its financial results for its
fiscal quarter ended June 30, 2007. The Company further expects to file its Form 10-Q on or about
August 16, 2007.
This Form 12b-25 contains “forward-looking statements” under the Private Securities Litigation
Reform Act of 1995 including those that involve risks and uncertainties related to the review by
the Audit Committee and the filing of delinquent reports on Form 10-K and Form 10-Q. Any
forward-looking statements contained in this Form 12b-25 are made pursuant to the safe harbor
provisions of the Private Securities Litigation Reform Act of 1995. You can identify these
forward-looking statements by the fact they use words such as “should,” “anticipate,” “estimate,”
“approximate,” “expect,” “target,” “may,” “will,” “project,” “intend,” “plan,” “believe” and other
words of similar meaning and expression. One can also identify forward-looking statements by the
fact that they do not relate strictly to historical or current facts. Forward-looking statements
are inherently subject to a variety of risks and uncertainties that could cause actual results to
differ materially from those projected. Although it is not possible to predict or identify all
risk factors, they may include the timing and final outcome of the ongoing review of the Company’s
stock option grant practices by the Audit Committee, including the related Securities and Exchange
Commission (“SEC”) investigation, shareholder derivative lawsuit, NASDAQ process regarding listing
of the common stock and tax matters, the timing of the completion and results of the audit of the
Company’s financial statements for the fiscal year ended March 31, 2007 and any actions that may be
required or taken as a result of such review, SEC investigation, shareholder derivative lawsuit,
NASDAQ process, tax matters or completion of the audit. We can give no assurance that any goal,
plan, date or target set forth in forward-looking statements can be achieved and readers are
cautioned not to place undue reliance on such statements, which speak
only as of the date made. We undertake no obligation to release publicly any revisions to forward-looking statements as a result
of future events or developments.
