MODTECH HOLDINGS, INC. RECEIVES NASDAQ DEFICIENCY LETTER

Perris, Calif.—April 29, 2008—Modtech Holdings, Inc., (Nasdaq: MODT) today announced that on April 24, 2008, it received a letter from The NASDAQ Stock Market notifying the company that, for the last 30 consecutive trading days, the publicly held shares of the company’s common stock had not maintained a minimum market value of $5 million as required for continued inclusion on The NASDAQ Global Market by Marketplace Rule 4450(a)(2). In accordance with Marketplace Rule 4450(e)(1), NASDAQ has given the company 90 calendar days, or until July 23, 2008 to regain compliance with the minimum market value rule. The notification has no effect on the listing of the company’s common stock at this time.

If at any time before July 23, 2008, the market value of Modtech’s publicly held shares of common stock is $5 million or greater for a minimum of 10 consecutive trading days, NASDAQ will provide the company with written notification that it has achieved compliance with Marketplace Rule 4450(a)(2) and Modtech’s shares will continue to trade on The NASDAQ Global Market. If Modtech does not regain compliance by July 23, 2008, the NASDAQ Staff will provide written notification that the company’s securities will be delisted. At that time, Modtech can appeal the Staff’s determination to a Listing Qualifications Panel.

Modtech is currently evaluating its alternatives to resolve the listing deficiency. If it is unable to resolve the listing deficiency, it may apply to transfer its common stock to The NASDAQ Capital Market if its securities satisfy the requirements for continued inclusion for that market. If Modtech submits a transfer application and pays the applicable listing fees by July 23, 2008, the initiation of the delisting proceedings will be stayed pending the NASDAQ Staff´s review of the application. If the Staff does not approve the transfer application, it will provide written notification to Modtech that its common stock will be delisted.
