FOR IMMEDIATE RELEASE

Morton Industrial Group, Inc. Announces 2002 Fourth Quarter and Year End Results

MORTON, IL — March 31, 2003 — Morton Industrial Group, Inc. (OTC: MGRP), a leading contract manufacturing supplier to large industrial original equipment manufacturers (OEMs), today announced its financial results for the 2002 fourth quarter and year ended December 31, 2002.

William D. Morton, Chairman, President and Chief Executive Officer of Morton Industrial Group, Inc., stated:  “We, like most American manufacturing companies, entered 2002 expecting our economy to improve during the last half of the year. This recovery did not materialize and, given the global challenges in front of us, may not do so during 2003. This will extend further the longest running economic constriction in American manufacturing since the Great Depression of 1929.

“We have made the long-term viability of Morton Industrial Group, Inc. our primary objective during this lingering downturn. To assure this, we have refocused on our core business, Morton Metalcraft Co., and determined that our recent expansion into contract plastics manufacturing, which created Morton Custom Plastics in 1998 and expanded it in 1999, should be discontinued.

“On December 24, 2002, we sold all of the assets of our five Morton Custom Plastics facilities located in Harrisburg and Concord, North Carolina; St. Matthews, South Carolina; and Lebanon, Kentucky, to Wilbert, Inc., an established contract plastics manufacturer servicing common capital goods industry customers.  We have also entered into discussions for the sale of the assets of our remaining Morton Custom Plastics facility located in West Des Moines, Iowa, requiring that we classify this business as ‘assets held for sale’ in our current financial statements.

“These actions allow us to concentrate all of our management attention on further developing Morton Metalcraft Co., our core business of contract metal fabrication manufacturing.”

The sales and operating income results from these continuing operations are referenced below. Details regarding earnings per share, discontinued operations, and the Company’s extended credit facility are available in the Company’s 10-K which may be accessed through the SEC’s EDGAR on-line system at www.sec.gov.

Net sales for the year ended December 31, 2002 from continuing operations were $116.6 million compared to $127.1 million for the year ended December 31, 2001.  The year over year sales decrease resulted primarily from the continued softness of the general economy negatively impacting unit demand from our major customers.   For the three months ended December 31, 2002, net sales from continuing operations rose to $26.2 million from $22.8 million in the same period a year ago. This resulted from the receipt of several major project awards from existing customers and the establishment of two new customers in diverse industries during the year.

Operating income from continuing operations for the year ended December 31, 2002 increased to $2.9 million from $1.3 million for the year ended December 31, 2001. For the three months ended December 31, 2002, the operating loss from continuing operations narrowed to $0.3 million from an operating loss of $3.6 million in the same period a year ago. This improved operating income during a year over year sales decrease resulted from the continued positive impact of our 6 Sigma initiative, which has lowered our overall operating costs.

Mr. Morton continued:  “We enter 2003 cautious of the global economic and political challenges that we and our customers are currently experiencing. But we are optimistic about the talent and resolve of our employees, the quality of our expanding customer base and the progress we’ve made in refocusing our business during 2002.”
