MATERIAL SCIENCES CORPORATION ANNOUNCES

SECOND QUARTER FISCAL 2007 RESULTS

ELK GROVE VILLAGE, IL, OCTOBER 10, 2006 – Material Sciences Corporation (NYSE: MSC), a leading provider of material-based solutions for acoustical and coated applications, today reported results for the second quarter of fiscal 2007, ended August 31, 2006.

Net sales for the second quarter were $67.3 million, a decline of nine percent from sales of $74.0 million in the second quarter of fiscal 2006. Net income for the quarter was $2.7 million, or 19 cents per diluted share, more than double net income of $0.9 million, or six cents per diluted share, in the comparable period last year.

“Significant reductions in the production schedules of our automotive customers during the second quarter negatively affected sales of automotive vehicles that contain our Quiet Steel^® acoustical products,” said Clifford D. Nastas, chief executive officer for Material Sciences. “However, despite the sales decline, our lean manufacturing and quality improvement initiatives implemented last year, combined with higher scrap prices, enabled us to sustain gross profit.”

“The domestic automotive manufacturers that are our largest customers are expected to maintain reduced production schedules through the balance of this fiscal year. We will have better clarity once they finalize their production schedules for the next six months.

“To lessen our reliance on the domestic automotive industry, we continue efforts to diversify our business by expanding our customer base and entering new sectors. Based on feedback from prospective customers, our investment in the Application Research Center will be a very important asset in our quest to penetrate new market segments,” Nastas added.

Results of Continuing Operations – Second Quarter Sales, Gross Profit and Income

In the first quarter of 2007, the Company began reporting sales under two types of applications, acoustical and coated, to better reflect its business mix. Electronic products sales are reported as acoustical sales when sold for disk drive applications and as coated sales when sold for all other electronic applications.

Acoustical material sales decreased 11.4 percent to $31.9 million from $36.0 million during the second quarter of fiscal 2006, primarily due to overall softness in the domestic automotive industry. Weakness in the automotive industry has led to a significant reduction in automobile sales and production, which, in turn, has reduced the demand for body panel laminate. Sales in the brake market declined 20.7 percent, mainly due to an inventory adjustment at one of our biggest customers in the aftermarket brake segment. Sales into the original equipment brake market increased reflecting our improved ability to solve noise issues quickly through the Application Research Center. Disk drive sales were down versus the second quarter of fiscal 2006 due to a change in disk drive design methodology at our largest customer in this sector.

Coated sales declined 6.8 percent in the second quarter to $35.4 million compared with $38.0 million in the prior period. Gas tank sales were impacted by softness in the auto industry, particularly a decline in the sale of sport utility vehicles. Lost business and general market fluctuations impacted appliance/HVAC sales during the quarter.

“Our investment in upgrading our coating commercial team combined with improvements in product quality have really helped offset the loss of the simulated stainless film product, which contributed $4.1 million of sales in the second quarter of fiscal 2006,” Nastas added.

Despite lower sales, gross profit in the second quarter increased to $13.3 million from $13.0 million in the second quarter of fiscal year 2006. Gross profit as a percent of sales increased to 19.8 percent of sales versus 17.6 percent of sales in the comparable period, a result of the quality improvement initiatives the company implemented in fiscal 2006, an increase in scrap prices, and a gain recorded on a raw material contract. These positive trends were partially offset by continued increases in the cost of certain raw materials compared with the prior year period. Gross profit was also negatively affected by changes in the Company’s product mix, and higher variable labor and overhead costs such as wages, variable energy costs and production supplies.

Selling, general and administrative expenses were $8.6 million in the second quarter, a slight decline from $9.2 million in last year’s quarter. The decrease is mainly due to the collection of a $0.3 million account receivable in the second quarter of fiscal 2007 that had previously been written off and environmental expenses of $0.5 million that were recorded in the second quarter of fiscal 2006, which did not repeat this year. These favorable expenses were partially offset by increased management incentive accruals of approximately $0.6 million in fiscal 2007.

Income from continuing operations for the second quarter was $2.7 million, or 19 cents per diluted share, compared with income from continuing operations of $2.0 million, or 14 cents per diluted share, last year.

Results of Discontinued Operations for the Quarter

As previously announced, the Company’s Electronic Materials & Devices (EMD) business was sold to TouchSensor Technologies on June 20, 2005, and the Company reports EMD as a discontinued operation in all periods presented. Management believes any future costs associated with the conclusion of EMD operations will be insignificant to the Company’s financial statements. The Company had no discontinued operations activity for EMD during the second quarter of fiscal 2007. However, the Company recorded losses on discontinued operations for EMD of $1.2 million, net of income taxes, in the second quarter of fiscal 2006.

Conference Call

Material Sciences will host a conference call to review the second quarter fiscal 2007 results on October 12, 2006, at 9:00 a.m. Central Daylight Time. Clifford D. Nastas, chief executive officer, and James M.
