Minerals Technologies Reports Fourth Quarter Diluted Earnings Per Share Of $0.86

January 31, 2008
    Company Records Net Loss of $3.31 per Share for Full Year 2007 Due
       to the Realignment Program Initiated in the Third Quarter

    Company Declares Regular Quarterly Dividend of $0.05 per Share

NEW YORK--(BUSINESS WIRE)--Jan. 31, 2008--Minerals Technologies Inc. (NYSE: MTX) today reported net income of $16.8 million, or $0.86 per share, for the fourth quarter 2007, compared with $10.5 million, or $0.55 per share in the same period of 2006.

"As part of the realignment and restructuring program initiated in the third quarter of 2007, the company recorded additional restructuring charges of $0.14 per share in the fourth quarter," said Joseph C. Muscari, chairman and chief executive officer. "However, these charges were largely offset by the initial savings generated from that program. The benefits of the restructuring will continue into 2008 with targeted annualized future savings between $15 million and $20 million."

Fourth quarter earnings included certain favorable special items. The company recognized a business interruption insurance recovery gain of approximately $0.10 per share and a similar amount for one-time compensation and employee benefit adjustments. In addition, the company realized favorable effects of an inventory revaluation in the fourth quarter due to the increasing cost of raw materials in the Refractories segment. This will result in higher cost of sales in the first quarter of 2008.

Fourth quarter results and all prior periods reflect the transfer of the Synsil(R) product line and the two plants in the Midwest that process imported ores to discontinued operations. The loss from discontinued operations was $0.03 per share in the fourth quarter of 2007 compared with a loss of $0.13 per share in 2006.

The company's worldwide sales in the fourth quarter increased 8 percent to $274.3 million compared with $254.8 million in the prior year. Foreign exchange had a favorable impact on sales of approximately 5 percentage points of growth. Operating income increased 7 percent to $24.1 million from the $22.4 million recorded in the same period in 2006.

Worldwide sales for the full year 2007 were $1.08 billion, a 5-percent increase over the $1.02 billion reported in 2006. For the year, foreign exchange had a favorable impact on sales of 3 percentage points of growth. The company recorded an operating loss for the full year 2007 of $8.5 million. Included in the loss from operations were an impairment of assets charge of $94.1 million and restructuring costs of $16.0 million.

As a result, the loss from continuing operations for 2007 was $25.7 million compared to a profit of $56.1 million in 2006. The loss from discontinued operations for the year was $37.8 million compared with a loss of $6.1 million in 2006. Included in the loss from discontinued operations was a pre-tax impairment of assets charge of $46.8 million and restructuring charges of $2.3 million. The net loss for the full year was $63.5 million compared with a profit of $50.0 million in 2006. The company's loss per share was $3.31 in 2007 compared with earnings of $2.53 per diluted share in 2006.

For the fourth quarter, worldwide sales in the company's Specialty Minerals segment, which consists of precipitated calcium carbonate (PCC) and Processed Minerals, were $180.4 million, a 9-percent increase over the $164.9 million in the same period of 2006. Foreign exchange had a favorable impact on sales for the quarter of approximately 5 percentage points of growth. For the full year 2007, Specialty Minerals sales increased 6 percent to $716.6 million compared with $675.6 million for 2006. Foreign exchange had a favorable impact on sales of approximately 3 percentage points of growth. For the fourth quarter, income from operations of $16.3 million increased 21 percent from the $13.5 million in the prior year. Included in income from operations were restructuring costs of $1.3 million in the fourth quarter of 2007. For the full year, Specialty Minerals incurred an operating loss of $20.0 million compared to a profit of $60.5 million recorded in the prior year. Included in the 2007 loss from operations were an impairment of assets charge of $79.3 million and restructuring costs of $11.3 million

Worldwide sales of PCC, which is used mainly in the manufacturing processes of the paper industry, increased 11 percent from $138.5 million in the fourth quarter of 2006 to $154.1 million in the same period of 2007. For the full year, PCC sales increased 8 percent from $557.0 million in 2006 to $602.6 million in 2007. Sales growth was attributable to increased selling prices from the pass through to customers of raw material cost increases and to foreign currency. Paper PCC sales volume decreased slightly from the prior year. Increased PCC volumes at several facilities were more than offset by paper industry consolidations, primarily in North America.

Worldwide sales of Processed Minerals products decreased slightly in the fourth quarter to $26.3 million from $26.4 million in the same period of the prior year. For the full year, Processed Minerals product sales decreased 4 percent to $114.0 million in 2007 from $118.6 million in 2006. This decrease was primarily due to weakness in the residential construction industry. Processed Minerals products, which include ground calcium carbonate and talc, are used in the building materials, polymers, ceramics, paints and coatings, glass and other manufacturing industries.

In the company's Refractories segment, sales in the fourth quarter were $93.9 million, a 4-percent increase over the $89.9 million recorded in the fourth quarter of 2006. Foreign exchange had a favorable impact on sales of $5.8 million for the fourth quarter. Sales for the full year for the Refractories segment were $361.1 million, a 4-percent increase over the $347.9 million in 2006. Foreign exchange had a favorable impact on sales of $11.9 million for the year, or 3 percentage points of sales growth. Sales from the Turkish acquisition made in late 2006 contributed an additional 4 percentage points of growth in 2007.

Operating income in the fourth quarter for the Refractories segment was $7.8 million, a 12-percent decrease from the $8.9 million recorded during the same period in 2006. Included in income from operations were restructuring costs of $2.6 million in the fourth quarter of 2007. For the full year, Refractories' operating income was $11.5 million, a 64-percent decrease from the $31.9 million recorded in the previous year. Included in income from operations were an impairment of assets charge of $14.8 million and restructuring costs of $4.7 million.

"The year 2007 was one of transition during which we took the necessary steps--by realigning and restructuring our operations--to strengthen our basic foundation," said Mr. Muscari. "We eliminated underperforming assets and will now be able to focus on our core competencies. In 2008, we expect to achieve higher returns on capital and higher rates of profitable growth. However, we are concerned about the state of the economy and the potential impact it may have on our product lines."

The company also declared a regular quarterly dividend of $0.05 per share on its common stock. The dividend is payable on March 19, 2008 to stockholders of record on February 28, 2008.

Minerals Technologies will sponsor a conference call tomorrow, February 1, at 11 a.m. The conference call will be broadcast live on the company web site: www.mineralstech.com.

2) In the third quarter of 2007, the Company initiated a plan to

 its operations. This realignment resulted in impairment of assets
 charges and restructuring charges for the fourth quarter and full
 year of 2007 from continuing operations as follows (millions of
 dollars):

                                          =====   =====

      The restructuring program will result in a reduction of
       approximately 200 employees, or 7%, of the company's worldwide
       workforce.

      The restructuring also resulted in inventory write-downs of $0.2
       million in the third quarter which were included in cost of
       goods sold.

      The impairment of assets charge for the full year includes a
       write-down of an intangible asset of $0.5 million related to
       customer relationships associated with a recent acquisition in
       the Refractories segment.



3) During the fourth quarter of 2006, the Company liquidated its
 wholly-owned subsidiary in Hadera, Israel and classified this
 business as a discontinued operation. The Company had previously
 operated a one-unit satellite PCC facility at this location.

   During the fourth quarter of 2007, the Company exited its Synsil(R)
    Products product line and reclassified such operations as
    discontinued. In addition, the Company reclassified to
    discontinued operations its two Midwest plants located in Mt.
    Vernon, Indiana and Wellsville, Ohio. All assets are classified as
    held for disposal as of December 31, 2007.

4) To supplement the Company's consolidated financial statements
 presented in accordance with GAAP, the following is a presentation of
 the Company's non-GAAP income (loss), excluding special items, for
 the fourth quarter and full year ended December 31, 2007 and 2006,
 respectively. The Company's management believes these non-GAAP
 measures provide meaningful supplemental information regarding its
 performance as inclusion of such special items are not indicative of
 the Company's ongoing operating results and thereby affect the
 comparability of results between periods. The Company feels inclusion
 of these non-GAAP measures also provides consistency in its financial
 reporting and facilitates investors' understanding of historic
 operating trends.
