Material Sciences Delivers Strongest Profit Performance in 11 Years for Fiscal 2011

ELK GROVE VILLAGE, IL, April 29, 2011—Material Sciences Corporation (NASDAQ: MASC), a leading provider of material-based solutions for acoustical and coated applications, today reported its first profitable year since fiscal 2007, and its strongest earnings per share performance in 11 years.

Net sales for fiscal 2011, ended February 28, 2011, were $137.6 million, stable with $137.8 million for fiscal 2010. The latest year reflected the sale of some coil coating assets in April 2010, which reduced revenues by $20.1 million in fiscal 2011 compared with fiscal 2010. Net income, however, reached $12.0 million, or 93 cents per common share, a turnaround from fiscal 2010’s net loss of $11.6 million, equal to 89 cents per common share.

Results Benefit from Expense Reductions, Growth Strategies, Noncore Asset Sales

“Fiscal 2011 net income was our strongest performance since 2000,” said Clifford D. Nastas, chief executive officer. “It’s now clear that our restructuring activities over the past three years combined with a commitment to operational excellence, product portfolio diversification, globalization and technical leadership have given Material Sciences the strong operating leverage to benefit from an improving global economy. These actions allowed us to continue expanding our gross margin—to 23.0 percent for the year—while reducing selling, general and administrative costs to 16.4 percent of revenues. Capitalizing on our global presence, we increased international sales 14.9 percent during the year. Growing acceptance of the innovative technologies we have commercialized —including ElectroBrite^®, Deco Steel^®, Quiet Steel^® and rubber coated metal—won us a number of new programs during fiscal 2011. This is helping us build share in markets we currently serve and reach new ones. While selling noncore coil coating assets reduced our sales by $20.1 million this year, this divestiture enabled us to focus on higher value segments with greater growth potential. As a result, we entered fiscal 2012 in a solid position to capitalize on the opportunities it offers.”

Higher Gross Margin, Operating Performance

Acoustical materials revenues were $73.1 million in fiscal 2011, up 9.3 percent from $66.9 million for the prior fiscal year. Higher demand for Quiet Steel in automotive brakes and engine-related products as well as new applications in the appliance market more than offset lower body panel laminate sales to General Motors.

Sales of coated materials for the latest year were $64.5 million compared with $70.9 million in fiscal 2010. The difference was largely due to the impact of the April 2010 coil coating asset sale mentioned earlier, plus lower fuel tank sales. These sales decreases were offset by stronger sales of electrogalvanized (EG) and gasket products used in the automotive market, plus the launch of several new ElectroBrite applications into the appliance market.

Gross profit nearly doubled, to $31.7 million in fiscal 2011 from $16.1 million a year ago. This led to a gross profit margin of 23.0 percent compared with 11.7 percent in fiscal 2010. The $15.6 million increase was primarily the result of a higher margin sales mix with more acoustical and EG revenue and lower coil coating sales, a reduction in production overhead costs, improved capacity utilization, quality improvements, and stronger pricing in the secondary scrap market.

Selling, general and administrative expenses (SG&A) decreased 14.7 percent between the two years, to $22.6 million from $26.5 million in fiscal 2010. As a percent of sales, SG&A in fiscal 2011 was 16.4 percent versus last year’s 19.3 percent. The $3.9 million decrease reflected lower headcount-related costs (from restructurings in fiscal 2010 and 2011), and a decline in professional fees and other discretionary spending. These expense reductions were partially offset by higher expenses from management and director incentive programs that accompanied increases in Material Sciences’ profitability and stock price.

Income from operations was $10.7 million, compared with a year-ago loss of $12.5 million. Total other income in fiscal 2011 more than doubled to $1.7 million from $0.7 million, mainly 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 $0.3 million versus a benefit of $0.1 million in fiscal 2010.

As a result, net income for the latest year was $12.0 million, or 93 cents per common share, a reversal of the net loss of $11.6 million, equal to 89 cents per common share, in fiscal 2010. A number of items related to the coil coating asset sale affected net income in 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 one-time facility shutdown-related costs of $1.0 million. The net impact of these items on fiscal 2011 income from operations was a positive $0.8 million.

Earnings before interest, taxes, depreciation and amortization (EBITDA) for fiscal 2011 was $17.8 million. This included net income of $12.0 million, plus provision for taxes of $0.3 million, minus net interest income of $0.1 million, plus depreciation of $5.6 million. The $17.8 million EBITDA was an improvement of $21.2 million over the prior year loss of $3.4 million.

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

Net Income Positive Compared with a Loss in Fourth Quarter Last Year

For the final three months of fiscal 2011, net sales were $31.9 million, down 10.9 percent from $35.8 million for this period last year. Divesting the coil coating assets accounted for a $5.7 million sales reduction from fiscal 2010. Gross profit was $8.8 million or 27.6 percent of sales, compared with $6.3 million or 17.6 percent of sales for the fourth quarter of fiscal 2010. Income from operations was $1.9 million versus a loss of $2.1 million for last year’s fourth quarter. Total other income for the most recent quarter was $0.6 million compared to $0.1 million in the prior-year’s three months. Net income was $2.4 million, or 18 cents per common share, in contrast to a loss of $2.0 million, equal to 16 cents per common share for the fourth quarter of fiscal 2010.

Strong Financial Condition

Net cash provided by operating activities for the latest year was $9.3 million compared with $2.8 million in fiscal 2010. The increase was primarily due to an improvement in net income, partially offset by an increase in working capital from higher inventory and accounts receivable. Material Sciences generated $13.5 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 due date. Capital improvements in fiscal 2011 were $2.4 million compared with $1.1 million in the prior year.

Fiscal 2012: Capitalizing on Opportunities

“The near-term outlook for our automotive markets is clouded by the effects of the recent tragic events in Japan, and that country’s ability to produce automotive parts,” explained Nastas. “To date, disruptions to our customer base have been minimal, but this can change suddenly as automotive manufacturers continue to manage the crisis one day at a time. We expect our consumer and industrial markets to continue their gradual upward movement.”

“Now that Material Sciences has more focused and efficient operations, we are turning our attention to expanding demand for our core and new innovative technologies. We believe that the capital investments planned for fiscal 2012 will generate long-term benefits by improving our overall competitiveness and making it easier for customers around the globe to do business with Material Sciences,” Nastas concluded.
