FOR IMMEDIATE RELEASE

Morton Industrial Group, Inc. Reports
Increases in Revenues and Profitability
for the 2004 Fiscal Year and Fourth Quarter

MORTON, IL — March 29, 2005 — Morton Industrial Group, Inc. (OTC BB: MGRP), which operates Morton Metalcraft Co., a leading metal fabrication supplier to large industrial original equipment manufacturers (OEMs), today announced its financial results for the fiscal year and fourth quarter ended December 31, 2004.

William D. Morton, Chairman and Chief Executive Officer of Morton Industrial Group, Inc., stated, “Our prestigious Customers, who serve the Construction, Agricultural and Commercial capital goods industries, experienced unanticipated rapid and strong increases in demand for their products throughout 2004, driven by the emerging and ongoing economic recovery, and which is continuing into 2005.

“In order to support our Customers’ increased assembly line requirements, we made significant investments in expanding our capacity by adding manpower and machines, as well as increasing our flow of materials. Also, this stronger business environment occurred in parallel with the restructuring of the U.S. Steel Industry, which caused the cost of cosmetically-sensitive steel - our core commodity — to nearly double. These higher steel costs were captured and passed through to our customers in the form of surcharges throughout 2004 and which is continuing in 2005.”

Excluding the impact of the steel surcharges passed through to our customers, net sales for the fiscal year ended December 31, 2004 were $167.3 million compared to $131.4 million for the fiscal year ended December 31, 2003, and $43.7 million for the quarter ended December 31, 2004 compared to $33.2 million for the quarter ended December 31, 2003. The sales increases in the 2004 fiscal year and fourth quarter resulted primarily from increased unit demand by existing customers.

Including the impact of the steel surcharges passed through to our customers of $18.2 million in the 2004 fiscal year and $5.0 million in the 2004 fourth quarter, net sales for the fiscal year ended December 31, 2004 were $185.5 million compared to $131.4 million for the fiscal year ended December 31, 2003, and $48.7 million for the quarter ended December 31, 2004 compared to $33.2 million for the quarter ended December 31, 2003.

Mr. Morton continued: “Our commitment to keep our customers’ production lines running added expenses to our operations during 2004, as we made significant strategic investments to secure longer-term customer satisfaction. Although we sacrificed short-term earnings in 2004, we are pleased with our improved operating performance, as operating income for the 2004 fiscal year rose to $8.8 million from $4.8 million in the 2003 fiscal year, and $2.3 million in the 2004 fourth quarter from $0.9 million in the 2003 fourth quarter.”

The Company’s net earnings reflect the operating improvement in 2004 and the effects of a gain on redemption of preferred stock of $2.8 million (with no comparable events in 2003) and an income tax benefit of $5.8 million (primarily recognizing in 2004 the benefits of the planned future utilization of net operating loss carryforwards).

Excluding the impact of the gain on redemption of preferred stock and the income tax benefit described above, net earnings available to common shareholders for the 2004 fiscal year were $4.2 million, or $0.70 per diluted share compared to $0.6 million, or $0.13 per diluted share in the comparable period a year ago. Net earnings available to common shareholders for the 2004 fourth quarter were $0.9 million, or $0.16 per diluted share compared to $0.3 million, or $0.06 per diluted share in the 2003 fourth quarter.

Including the impact of the gain on redemption of preferred stock and the income tax benefit described above, net earnings available to common shareholders for the 2004 fiscal year were $12.8 million, or $2.16 per diluted share compared to $0.6 million, or $0.13 per diluted share in the comparable period a year ago. Net earnings available to common shareholders for the 2004 fourth quarter were $7.5 million, or $1.25 per diluted share compared to $0.3 million, or $0.06 per diluted share in the comparable period a year ago.

Mr. Morton commented: “With sufficient capacity now in place, we expect 2005 to produce improved performance for our Customers and ongoing stable financial results for our Company. Morton Metalcraft Co. remains committed to the use of 6 Sigma methodologies, which continue to improve efficiencies throughout our Company.

“Looking ahead, we believe there will continue to be many challenges that face the Construction, Agricultural and Commercial original equipment manufacturers and members of their supply networks such as Morton Industrial Group, Inc. We believe that we are well positioned to be able to respond to these challenges and meet them successfully.”
