MODTECH HOLDINGS INC.

REPORTS FOURTH-QUARTER, TWELVE-MONTH 2004 RESULTS

Quarterly Sales Rise, Losses Narrow

Perris, Calif.—March 30, 2005—Modtech Holdings, Inc. (Nasdaq: MODT) reported financial results for fourth quarter and twelve months ended December 31, 2004.

Revenues for the quarter rose to $46.7 million from $23.1 million in fourth-quarter 2003 due primarily to higher sales in California and Florida, a focus on new markets, and the restoration of key customer relationships. Cost of sales were $44.2 million, versus $26.2 million last year. The additional increases in costs were due to the corresponding increase in revenues, adjustments on underbid jobs, and write-downs for project overruns and obsolete inventory. Gross profit for the quarter was $2.5 million compared to a loss of $3.1 million in fourth-quarter 2003. This improvement was primarily due to the renegotiation of several major projects, and the increase of more profitable, quick turnaround projects in Florida, Arizona, and California non-education.

Sales, general, and administrative (SG&A) expenses were $3.5 million compared to $2.4 million in 2003. The $1.1 million increase was due primarily to Sarbanes Oxley compliance costs, and restructuring costs. Operating loss for the quarter was $1.1 million compared to operating losses of $5.5 million in fourth-quarter 2003. Net loss for the quarter was $1.3 million, or 9 cents per share, compared to a net loss of $3.2 million, or 24 cents per share, for fourth-quarter 2003.

Revenues for the year rose to $186.7 million from $159.9 million in 2003 due primarily to higher sales outside the California classroom market. Cost of sales increased to $183.9 million from $147.9 million from 2003. This $36 million increase in 2004 was primarily due to the increase in sales, restructuring costs, and compliance costs.

SG&A expenses for 2004 rose to $14.5 million from $8.1 million in 2003. Of the $6.4 million increase in 2004, $2.1 million was related to restructuring costs, $1.8 million was related to compliance costs, with the remaining amount due to increases in operations. Operating loss for the year was $11.0 million, compared to operating income of $3.7 million for 2003. Net loss for the year, including a benefit for taxes of $5.1 million, was $7.9 million, or 58 cents per share, compared to net income of $1.5 million, or 11 cents per share, in 2003.

Modtech President and Chief Executive David Buckley commented: “2004 was clearly a year of significant change for Modtech. While we have addressed the major issues facing the company in 2004, there is still a great deal of work to be done to bring costs in line and to improve overall margins. In addition to addressing specific operational issues, we are continuing our efforts to change the Company’s business culture, including a core set of beliefs, and a clear focus on operational efficiency.”

“The key focus for improving operational efficiencies is our launch of a Lean Enterprise initiative. Early indications are very positive to the kinds of changes that can be made to the way we do business. These efforts are clear, fast, and have had an immediate impact on the first areas of concentration, such as the Request for Proposal process. Along with our Lean efforts, we are also moving forward with National supplier agreements, infrastructure improvements, technology improvements, and a strict focus on inventory and cash management. At the end 2004, and into early 2005, we completed our re-financing plans and we now have sufficient capital to support our turnaround and growth strategy.”

“From a top-line perspective, we continue to move toward additional markets that will allow us to limit our reliance on the California education sector. While we will continue to focus on and expand our California education business, we are accelerating our efforts to expand toward additional, new markets where we see stronger sales opportunities and profit potential,” Buckley continued. “For example, in the fourth-quarter, California education sales were 50% of total revenues, compared to 58% for the previous three quarters. This growth outside of California education was partially the result of new sales and marketing efforts, and also partly due to much-improved relationships with former key customers.”

“To further expand and maintain momentum, we have restructured the Company’s operations into regions with General Managers who have full profit and loss accountability” added Buckley. “Consistent with this realignment, the manufacturing operations in Northern California are closing as scheduled on April 4, 2005. One area of recent concern was the record-setting rains which occurred in California in December, January, and February. This rainfall will have little to no impact on attained sales, but the rains did postpone revenue recognition due to the inability to work on-site for more than 4 weeks during this period. We feel this should only marginally affect our outlook for 2005, especially since we were, and still are, expecting continual improvement in revenue and cost lines as the year progresses.”

Modtech Chief Financial Officer Dennis Shogren remarked: “Our efforts to improve cash flow, increase productivity, and increase efficiency are starting to pay off. We are seeing improvements in the areas where we concentrate the bulk of our efforts. We are seeing clear evidence that the Company’s turnaround is moving forward. We will continue to work through each issue while we continue to focus on our goals for 2005”.
