Minerals Technologies Inc. Reports Second Quarter Diluted Earnings Per Share of $0.63

July 27, 2006

NEW YORK--(BUSINESS WIRE)--July 27, 2006--Minerals Technologies Inc. (NYSE: MTX) today reported second quarter net income of $12.6 million, a 4-percent decrease from the $13.1 million reported in the second quarter of 2005. Diluted earnings per common share were $0.63, the same as reported in the second quarter of last year.

"As we announced in June, the company did not achieve the increase in operating income expected during the quarter," said Paul R. Saueracker, chairman, president and chief executive officer.

Worldwide sales in the quarter increased 9 percent to $266.5 million from $244.7 million in the previous year. Foreign exchange had a minimal unfavorable impact on sales. Income from operations was $20.9 million in the second quarter, slightly above the prior year.

Worldwide sales for the first six months of 2006 increased 7 percent to $532.5 million from $495.5 million reported last year. Foreign exchange had an unfavorable impact on sales of approximately $6.1 million or 1 percentage point of growth. Operating income for the first six months of 2006 was $39.8 million, an 11-percent decrease from the $44.9 million reported in the first half of 2005.

For the first six months of 2006, net income decreased 11 percent to $25.4 million from $28.4 million last year. Diluted earnings per common share decreased 7 percent to $1.27 from $1.36 for the same period in 2005.

"In a comparison of the second quarter of 2006 with the same period last year, our operating income improved only slightly as a result of a number of factors," said Mr. Saueracker. "These included unrecovered raw material and energy cost increases; reduced contributions from the metallurgical product line; paper mill and paper machine shutdowns affecting several satellite PCC facilities; and, increased market development and ramp-up costs for our SYNSIL(R) Products.

"Partially mitigating these factors were improved paper industry operations in Finland, which had faced labor disputes in the second quarter of last year; improved operations of our two large satellite precipitated calcium carbonate (PCC) plants in China; and the ramp up of our European coating program," said Mr. Saueracker.

Sales in the Specialty Minerals segment, which includes the PCC and Processed Minerals product lines, increased 12 percent to $179.6 million from $160.7 million in the comparable quarter of 2005. Income from operations for the second quarter of 2006 was $13.3 million, a 9-percent increase over the $12.2 million reported the previous year. For the first six months of 2006, Specialty Minerals sales increased 10 percent to $362.1 million from $330.5 million in the same period in 2005. Income from operations for the six months decreased 11 percent to $25.5 million from $28.6 million in the first half of last year.

Worldwide net sales of PCC, which is used primarily in paper manufacturing, increased 12 percent in the second quarter to $137.8 million from $122.9 million in the same period in 2005. Total PCC sales for the first six months of 2006 were $281.1 million, a 9-percent increase from $256.9 million in the prior year.

For the second quarter, Paper PCC sales grew 14 percent to $123.7 million from $108.8 million in the prior year. For the first half of 2006, Paper PCC sales grew 10 percent to $251.9 million.

"Paper PCC achieved sales growth in all regions during the second quarter as total worldwide unit volumes grew 11 percent," said Mr. Saueracker. "Four percentage points of this growth were attributable to the ramp-up of volumes from new facilities in China and Germany and 3 percentage points of growth were due to the resumption of operations in Finland that had been affected by the labor actions in 2005. Strong demand and satellite PCC expansions more than offset the volume losses associated with the paper mill shutdowns."

Sales of Specialty PCC in the quarter were essentially flat compared to prior year at $14.1 million. For the first six months of 2006, Specialty PCC sales increased 3 percent to $29.2 million from $28.4 million.

Sales of Processed Minerals products for the second quarter were $41.8 million, an 11-percent increase over the $37.8 million reported for the same period in 2005. Talc sales increased 18 percent to $16.1 million from $13.7 million in the prior year due to strong global demand for plastics and consumer-related markets. For the six months, sales of Processed Minerals products increased 10 percent to $81.0 million from $73.6 million in the first half of 2005. Processed Minerals products are used in the building materials, polymers, ceramics, paints and coatings, glass and other manufacturing industries.

Second quarter net sales in the Refractories segment, which primarily serves the steel industry, increased 3 percent to $86.9 million from $84.0 million in the same period of 2005. Sales in the metallurgical product line decreased 15 percent to $20.8 million from $24.5 million in the second quarter of 2005. Sales of refractory products and systems to steel and other industrial applications increased 11 percent to $66.1 million from $59.5 million in the prior year. Income from operations for the Refractories segment in the second quarter of 2006 decreased 12 percent to $7.6 million from $8.6 million in the same period last year.

"The Refractories segment experienced strong demand for its refractory products and systems during the quarter," said Mr. Saueracker. "The decline in sales in the metallurgical product line, however, was attributable primarily to lower prices as a result of a reduction in raw material costs passed through to customers."

For the six months, sales in the Refractories segment increased 3 percent to $170.4 million from $165.0 million in the same period in 2005. However, income from operations for the six months decreased 12 percent--from $16.3 million for the first six months of 2005 to $14.3 million. The decline in operating income for the six months was due to lower margins in the metallurgical product line, and additional costs related to new business development activities.

Mr. Saueracker concluded: "We are disappointed with the company's operating income performance for the second quarter, but looking forward, we believe that our results will improve through the remainder of the year,"

The company has scheduled an analyst conference call for Friday, July 28, 2006 at 11:00 a.m. to discuss operating results for the second quarter. The conference call will be broadcast over the company's website, www.mineralstech.com.

1) For the periods ended July 2, 2006 and July 3, 2005.

2) Sales increased 8% in the United States in both the second quarter
   and for the first six months of 2006. International sales
   increased approximately 11% in the second quarter and 6% for the
   first six months of 2006.

3) Provisions for bad debt, included in marketing and administrative
   expenses, increased $1.1 million in the second quarter and $1.6
   million for the first six months of 2006. The provisions for bad
   debt were $0.3 million and $1.3 million for the second quarter and
   first six months of 2006, respectively. In the second quarter of
   2005, recoveries of bad debt were in excess of provisions.

4) On January 1, 2006, the Company adopted the fair value recognition
   provisions of SFAS No. 123R, "Share-Based Payment," using the
   modified-prospective transition method. Under this transition
   method, stock-based compensation was recognized in the financial
   statements for granted, modified or settled stock options.
   Compensation expense recognized included the estimated expense for
   stock options granted in the first half, based on the grant date
   fair value estimated in accordance with the provisions of SFAS
   123R, and the estimated expense for the portion vesting in the
   first half for options granted prior to, but not vested as of
   January 1, 2006, based on the grant date fair value estimated in
   accordance with the original provisions of SFAS 123. Stock-based
   compensation expense relating to these options recognized in
   marketing and administrative expenses in the consolidated
   statement of income in the second quarter and first six months was
   $0.6 million and $1.1 million, respectively. The related tax
   benefit on the non- qualified stock options was $0.1 million and
   $0.2 million in the second quarter and first six months,
   respectively.

5) On January 1, 2006, the Company adopted the consensus of Emerging
   Issues Task Force ("EITF") Issue No. 04-06, "Accounting for
   Stripping Costs Incurred During Production in the Mining
   Industry." This consensus states that stripping costs incurred
   during the production phase of a mine are variable production
   costs that should be included in the costs of inventory produced
   during the period that the stripping costs are incurred. The
   Company had previously deferred stripping costs in excess of the
   average life of mine stripping ratio and amortized such costs on a
   unit of production method. As a result of this consensus, the
   Company recorded an after-tax charge to opening retained earnings
   of $7.1 million and increased its opening inventory by $0.8
   million. The change in accounting did not have a significant
   impact on the second quarter or the first six months earnings.

6) During the first quarter of 2006, the Company recognized an
   insurance settlement gain of approximately $1.8 million for
   property damage sustained at the Easton, Pennsylvania facility in
   2004 related to Hurricane Ivan. Such amount is included in
   non-operating deductions (income) for the six month period ended
   July 2, 2006.

7) The results of operations for the interim period ended July 2, 2006
   are not necessarily indicative of the results that ultimately
   might be achieved for the current year.

8) The analyst conference call to discuss operating results for the
   second quarter is scheduled for Friday, July 28, 2006 at 11:00
   a.m. and will be broadcast over the Company's website
   (www.mineralstech.com). The broadcast will remain on the Company's
   website for no less than one year.
