Material Sciences Continues to Improve Profitability

for Third Quarter, Nine Months

ELK GROVE VILLAGE, IL, January 14, 2011—Material Sciences Corporation (NASDAQ: MASC), a leading provider of material-based solutions for acoustical and coated applications, today reported its third-consecutive profitable quarter and increasing net income for its nine months ended November 30, 2010.

Net sales for the latest three months were off 23.0 percent, primarily due to the sale of certain coil coating assets earlier in the year, to $30.1 million from $39.1 million a year ago. However, net income was $1.7 million, or 13 cents per common share, compared with a net loss of $2.0 million, equal to 15 cents per common share, in last year’s third quarter.

Growth Strategies Continue to Improve Performance

“We ended the quarter and nine-month period with our best net income performance in five years,” said Clifford D. Nastas, chief executive officer. “Third quarter results were buoyed by good markets for our products, but the bulk of the improvements came from following our strategies for growth. We maintained the operating leverage built over the last two years by ensuring the size of our company matched its growth opportunities. This, combined with progress made on our operational excellence initiatives, was a significant contributor to our increased gross profit and reduced spending. We continued to benefit from our investments in Europe and Asia, which is reflected by a 14 percent increase in non-domestic sales over last year’s nine months. Customer response and acceptance of our innovative technologies—such as ElectroBrite®, ViviColor®, Quiet Steel® and rubber coated metal—remained strong as we enjoyed new wins during the quarter. And while divesting non-strategic operations reduced our sales, it enables management to better focus on its execution of our growth strategies, as well as expanding the amount of cash we have to invest in higher value segments to provide even greater growth moving forward.”

Gross Margin, Earnings Improve Despite Lower Third Quarter Sales

Sales of acoustical materials—most often to automotive manufacturers—were $17.7 million compared with $19.8 million for last year’s third quarter, off 10.4 percent. This reflected decreased Quiet Steel shipments to one automotive customer, partially offset by higher body panel laminate sales to another, and a new Quiet Steel application in the appliance market.

Revenues for coated materials—primarily used in the automotive industry—at $12.4 million decreased 35.9 percent from $19.4 million for the year-ago quarter. The difference was largely due to the April 2010 coil coating asset sale, which resulted in a $6.9 million revenue reduction for the latest three months. However, this was partially offset by greater demand for electrogalvanized and gasket products.

Gross profit saw a 57.4 percent increase in the quarter, to $6.8 million from $4.3 million in the prior-year period. As a result, the gross profit margin reached 22.5 percent compared with 11.0 percent in last year’s third quarter. The $2.5 million rise came largely from improvements in quality and higher secondary scrap sales, as well as higher margin products.

Selling, general and administrative expenses (SG&A) were 17.2 percent lower in the most recent three months, at $5.6 million compared with $6.8 million. As a percentage of sales, SG&A in the latest quarter was 18.5 percent in contrast to 17.3 percent for the same period last year, reflecting the lower level of sales. The $1.2 million reduction came from lower salary and people-related costs (from restructurings in fiscal 2010 and 2011), and a decrease in professional fees.

Income from operations was $1.2 million in contrast to a loss of $2.4 million in the third quarter last year. Total other income in the latest quarter doubled to $0.4 million from $0.2 million, due to rental income received from the lease of the Elk Gove Village plant in conjunction with the coil coating asset sale. The provision for income taxes was a $0.1 million benefit for the three months versus a $0.2 million benefit in the year-ago period. Net income was $1.7 million, or 13 cents per common share, an improvement from the net loss of $2.0 million, equal to 15 cents per common share, in last year’s third quarter.

Higher Sales, Gross Margin, Profits for Nine Months

For the first nine months of fiscal 2011, net sales rose 3.6 percent to $105.7 million from $102.1 million. This reflected a 17.4 percent increase in acoustical materials sales, which more than offset the 9.2 percent reduction in coated materials sales, primarily due to a $14.9 million decrease in revenues because of the April 2010 asset sale. Gross profit was $22.9 million or 21.6 percent of sales, compared with $9.8 million or 9.6 percent of sales in for the first nine months of last year. SG&A of $15.8 million in the latest period was 21.6 percent lower than the $20.2 million in the prior year, for a decrease of $4.4 million. Income from operations was $8.8 million, improved from a $10.4 million loss for the prior-year’s nine months. Total other income for the most recent period was $1.1 million in contrast to $0.6 million for the same period last year. Net income was $9.7 million, or 75 cents per common share, compared with a loss of $9.7 million, equal to 74 cents per common share, for last year’s nine months. A number of items related to the coil coating asset sale affected net income in the first nine months of fiscal 2011. These included a gain on the sale of assets of $6.6 million, real property impairment expense of $3.7 million, restructuring expense for severance of $1.1 million and a one-time facility shutdown- related cost of $1.0 million.

Earnings before interest, taxes, depreciation and amortization (EBITDA) for year-to-date fiscal 2011 reached $14.1 million. This included net income of $9.7 million; plus provision for taxes of $0.2 million; less interest income of $0.06 million; plus depreciation of $4.3 million.

Management believes that EBITDA is an important metric used by investors and analysts to review Material Sciences’ historical results. However, it should not be considered as an alternative to net income or operating income as an indicator of the company’s operating performance, or as an alternative to operating cash flows for measuring liquidity.

Strong Financial Condition

Net cash provided by operating activities for the most recent nine months was $8.6 million compared with $4.5 million in the same period last year. The increase was primarily due to higher net income, partially offset by a lower improvement in inventory levels when compared with the prior year, and other working capital changes. Material Sciences generated $14.4 million of net cash from investing activities, reflecting the sale of coil coating assets at Middletown, Ohio, and Elk Grove Village, Illinois, and the collection of a note receivable before its scheduled payment date. Capital improvements for the first nine months of fiscal 2011 were $1.4 million versus $0.8 million in the prior-year period.

Due to amendments and actuarial changes to its retiree health care plan, the company lowered that long-term liability by $2.4 million at the end of the third quarter.
