ELK GROVE VILLAGE, IL, MARCH 19, 2007 - Material Sciences Corporation (NYSE: MSC), a leading provider of material-based solutions for acoustical and coated applications, today announced that it filed its Form 10-Q for the third quarter of fiscal 2007, ended November 30, 2006, with the Securities and Exchange Commission.

On January 10, 2007, Material Sciences reported preliminary results of operations before income taxes and delayed filing its Form 10-Q subject to completing a review of its deferred tax balances.

The company has completed its review of deferred tax balances and recorded a tax benefit of $0.3 million in the third quarter of fiscal 2007. This benefit was not material to the fiscal year or any prior period financial statements. The previously released results from operations before income taxes did not change.

The total tax benefit for continuing operations was $0.7 million in the third quarter of fiscal 2007 compared with a provision of $1.5 million in the third quarter of last year. The tax benefit recorded in the third quarter of fiscal 2007 also included a $0.3 million tax benefit related to the completion of an audit by the Internal Revenue Service.

The company reported a net loss for the quarter of $0.2 million, or a loss of one cent per diluted share, compared with net income of $2.2 million, or income of 15 cents per diluted share, in the comparable period last year.
