     The accompanying unaudited condensed consolidated financial statements have been prepared by management in accordance with the rules and regulations of the United States Securities and Exchange Commission. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted. Therefore, these financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2001. In the opinion of management, all adjustments, consisting solely of normal recurring adjustments necessary for a fair presentation of the financial information for the periods indicated, have been included. The results for the three-month and nine-month periods ended September 29, 2002 are not necessarily indicative of the results that may be expected for the year ending December 31, 2002.

     The following is a summary of inventories by major category:

     The following is a summary of long-term debt:

     Basic earnings per share are based upon the weighted average number of common shares outstanding during the period. Diluted earnings per share are based upon the weighted average number of common shares outstanding during the period assuming the issuance of common shares for all dilutive potential common shares outstanding. The following table sets forth the computation of basic and diluted earnings per share:

     The following are the components of comprehensive income (loss):

The components of accumulated other comprehensive loss, net of related tax are as follows:

     Segment information for the three-month and nine-month periods ended September 29, 2002 and September 30, 2001 was as follows:

     Included in income from operations of the Specialty Minerals segment for the nine months ended September 29, 2002, is a write-down of impaired assets of $0.8 million. In the second quarter of 2001, a restructuring charge of approximately $3.0 million and $0.4 million was included in income from operations for the Specialty Minerals segment and Refractories segment, respectively.

     The following is a schedule of amortization expense related to goodwill by segment:

     The carrying amount of goodwill by reportable segment as of September 29, 2002 and December 31, 2001 was as follows:

     A reconciliation of the totals reported for the operating segments to the applicable line items in the condensed consolidated financial statements is as follows:

     On February 6, 2002, the Company acquired from J.M. Huber Corporation of Edison, New Jersey a merchant precipitated calcium carbonate plant located in Hermalle-sous-Huy, Belgium. The plant has the capacity to produce approximately 60,000 tons of PCC annually. The Company acquired this plant to accelerate the development of its European coating PCC program. The purchase price was $10.2 million, which included acquisition costs and assumed liabilities. The terms of the acquisition also provide for additional consideration of $1.0 million to be paid if certain volumes of coating PCC are produced and shipped from this facility for any six consecutive months within five years following the acquisition. Approximately $0.1 million of the purchase price was assigned to goodwill. The operations of this entity have been included in the Company's financial statements since the date of its acquisition.

     On April 26, 2002, the Company acquired the assets of Thermo Radiometrie Oy and all of the outstanding shares of Thermo Radiometrie K.K. (collectively, Radiometrie). Radiometrie develops and manufactures a refractory lining monitoring system used to measure and monitor ceramic refractory linings of steel converters and ladles. The purchase price was $1.4 million, which included acquisition costs and assumed liabilities. Approximately $0.1 million of the purchase price was assigned to goodwill. The operations of this entity have been included in the Company's financial statements since the date of its acquisition.

     On September 9, 2002, the Company acquired the business and assets of Polar Minerals Inc. ("Polar"), a privately owned producer of industrial minerals in the midwest United States. The purchase price was $22.5 million. The final appraisal of the business and assets has not been completed as of September 29, 2002. The Company has estimated that approximately $4.7 million of the purchase price will be assigned to goodwill and has included that amount in the financial statements. The operations of this entity have been included in the Company's financial statements since the date of acquisition.

     Effective January 1, 2002, the Company adopted Statement of Financial Accounting Standards (SFAS) No. 142, "Goodwill and Other Intangible Assets." Under SFAS No. 142, goodwill and other intangible assets with indefinite lives will no longer be amortized, but instead reviewed for impairment at least annually in accordance with the provisions of SFAS No. 142. This statement also required an initial goodwill impairment assessment in the year of adoption. The Company completed the initial impairment analysis. The analysis did not result in an impairment charge.

     The carrying amount of goodwill was $50.1 million and $43.5 million as of September 29, 2002 and December 31, 2001, respectively. The net change in goodwill since January 1, 2002 was primarily attributable to the acquisition of Polar.

     The following table reconciles previously reported net income as if the provisions of SFAS No. 142 had been in effect in 2001:

     Acquired intangible assets subject to amortization as of September 29, 2002 and December 31, 2001 were as follows:

     The weighted average amortization period for acquired intangible assets subject to amortization is approximately 15 years. Estimated amortization expense is $0.4 million for each of the next five years through 2007.

     The Company accounts for impairment of long-lived assets in accordance with SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets." SFAS No. 144 establishes a uniform accounting model for long-lived assets to be disposed of. This Statement also requires that long-lived assets be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by comparing the carrying amount of an asset to future net cash flows expected to be generated by the asset. If the carrying amount of the asset exceeds its estimated cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds the fair value of the asset. During the first quarter of 2002, the Company recorded a write-down of impaired assets of $750,000 for a precipitated calcium carbonate plant at a paper mill that had ceased operations. Such charge is included in cost of goods sold for the nine months ended September 29, 2002.

The Board of Directors and Shareholders
Minerals Technologies Inc.:

       We have reviewed the condensed consolidated balance sheet of Minerals Technologies Inc. and subsidiary companies as of September 29, 2002 and the related condensed consolidated statements of income for each of the three-month and nine-month periods ended September 29, 2002 and September 30, 2001, and cash flows for the nine-month periods then ended. These financial statements are the responsibility of the company's management.

       We conducted our review in accordance with standards established by the American Institute of Certified Public Accountants. A review of interim financial information consists principally of applying analytical procedures to financial data and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with auditing standards generally accepted in the United States of America, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

       Based on our review, we are not aware of any material modifications that should be made to the condensed consolidated financial statements referred to above for them to be in conformity with accounting principles generally accepted in the United States of America.

       As discussed in Note 8 to the condensed consolidated financial statements, effective January 1, 2002, the Company adopted the provisions of SFAS No. 142, "Goodwill and Other Intangible Assets."

       We have previously audited, in accordance with auditing standards generally accepted in the United States of America, the consolidated balance sheet of Minerals Technologies Inc. and subsidiary companies as of December 31, 2001, and the related consolidated statements of income, shareholders' equity, and cash flows for the year then ended (not presented herein); and in our report dated January 22, 2002, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidated balance sheet as of December 31, 2001 is fairly presented, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

Results of Operations

     Net sales in the third quarter of 2002 increased 9.8% to $192.1 million from $174.9 million in the third quarter of 2001. Foreign exchange had a favorable effect on sales of approximately $1.5 million or 0.9 percentage points of growth.

     Worldwide net sales of PCC, which is used primarily in the manufacturing process of the paper industry, increased 9.0% to $107.6 million from $98.7 million in the third quarter of 2001. Sales volume for PCC used for filling and coating paper increased 10%. This increase was primarily due to the ramp-up of the ten new units of precipitated calcium carbonate capacity that were added in 2001 and increased volume worldwide from several long-standing satellite facilities. These volume increases more than compensated for the closure of several satellite PCC facilities in the United States. A unit represents approximately 30,000 tons of annual PCC production.

     Net sales of the Specialty PCC product line, which is used in non-paper applications, increased 4.2% from the prior year. This increase was attributable primarily to increased volume from the Brookhaven, Mississippi facility. However, this facility is still operating well below capacity levels and the overall profitability of this product line continues to be affected by weak industry conditions and a competitive environment in the calcium supplement market.

     Net sales of Processed Minerals products increased 8.9% in the third quarter to $24.5 million from $22.5 million in the same period the prior year. Approximately 6 percentage points of the sales growth were attributable to the acquisition of Polar Minerals Inc. on September 9, 2002.

     Net sales in the Refractories segment increased 11.7% to $60.0 million as compared with $53.7 million in the prior year. Approximately 9 percentage points of the increase in sales were the result of the acquisition of Rijnstaal B.V., a Netherlands-based producer of cored metal wires used mainly in the steel and foundry industries, in the third quarter of 2001.

     Net sales in the United States in the third quarter of 2002 increased approximately 6% as compared with the third quarter of 2001. The 6% sales increase in the U.S. occurred in both business segments. International sales increased approximately 17% in the third quarter of 2002. This was primarily due to strong sales in Europe in both business segments and to the acquisitions in Belgium and the Netherlands.

     Cost of goods sold was 75.8% of sales compared with 73.7% in the prior year. An increase in cost of goods sold as a percentage of sales occurred in both reporting segments. Cost of goods sold as a percentage of sales for the Specialty Minerals segment increased slightly primarily as a result of the financial effect of the shortened periods over which existing satellite plants at International Paper Company ("IP") mills are depreciated, continued development activities for coating-grade PCC associated with the acquisition of a PCC plant in Belgium and continued weakness in the Specialty PCC product line. Cost of goods sold as a percentage of sales for the Refractories segment increased due to volume losses as a result of slowdowns and closures in high margin integrated steel mill accounts, inventory and production problems at certain facilities in North America, and increased development costs associated with new products and systems.

12

     Marketing and administrative costs were approximately 10.1% of sales compared with 10.5% of sales in the prior year. Although the Company's sales and marketing staff increased as a result of the recent acquisitions, these costs were largely offset by the benefits of the prior year's restructuring.

     Income from operations decreased 1.9% to $21.6 million, as compared with $22.1 million for the same period last year. There was no amortization related to goodwill in the third quarter of 2002. Amortization related to goodwill was $0.4 million in the third quarter of 2001. Operating income in the Specialty Minerals segment represented 12.8% of its net sales and increased 9.8% to $16.9 million from $15.4 million in the prior year. The Refractories segment's operating income decreased 29.1% to $4.7 million and was 7.8% of its net sales. This decrease was attributable to the aforementioned decrease in production margin and higher expenses.

     Non-operating deductions decreased due to lower interest rates and lower average borrowings.

     Net income increased 4.6% to $14.2 million from $13.6 million in the prior year. Diluted earnings per share were $0.70 in the third quarter of 2002 as compared with $0.68 in the prior year.

     On September 9, 2002, the Company acquired the business and assets of Polar Minerals Inc. ("Polar"), a privately owned producer of industrial minerals in the Midwest United States. The purchase price was $22.5 million. Polar had sales in 2001 of approximately $24.1 million.

     Several consolidations in the paper industry have taken place in recent years. Such consolidations concentrate purchasing power in the hands of a smaller number of papermakers, enabling them to increase pressure on suppliers. This increased pressure could have an adverse effect on the Company's results of operations in the future. In addition, these consolidations could result in partial or total closure of some paper mills at which the Company operates PCC satellites. In particular, the Company's largest customer, IP, decided during 2000 to reduce production capacity by closing four paper mills at which the Company has satellite PCC plants. These closed mills are located in Mobile, Alabama; Lock Haven, Pennsylvania; Erie, Pennsylvania; and Oswego, New York. Sales to IP represented approximately 10.8% and 11.5% of consolidated net sales for the three-month and nine-month periods ended September 29, 2002, respectively. In addition, during 2000 two paper companies filed for bankruptcy protection and closed their paper mills in Plainwell, Michigan and Anderson, California, at which the Company had satellite PCC plants.

     Excluding the aforementioned plants that have been closed, there are two satellite locations at which contracts with host mills have expired and one location, representing less than one unit of PCC production, at which the host mill has informed the Company that the contract will not be renewed upon its expiration in 2004, although the Company continues to supply PCC at all of these locations. At one of these locations the Company hopes to reach agreement on a long-term extension of the contract; however, there can be no assurance that these negotiations will be successful. At the other location the customer, IP, has informed the Company that it intends to begin negotiations with alternative suppliers. The Company continues to supply PCC at this location, and expects to continue to do so through 2003. IP also informed the Company at the end of the second quarter that it will honor all existing satellite contracts; however, it expects to negotiate with other suppliers at other satellite locations as the contracts for those locations expire over the next several years, with the last contract expiring in 2010. That decision by IP increases the risk that some or all of these contracts will not be renewed. The loss of a substantial amount of the Company's sales to IP would have a material effect on the Company's results of operations and projected growth rate; however, because these contracts have various remaining terms, the full impact would not be felt for several years.

     In recognition of this increased risk, the Company has shortened the periods over which existing satellite plants at IP mills are depreciated. The shortened depreciation schedule reduced diluted earnings per share by approximately $0.02 per share in the third quarter of 2002, and will reduce diluted earnings per share by approximately $0.02 per share in the fourth quarter of 2002, $0.08 per share in 2003, 2004 and 2005, and $0.04 per share in 2006.

     Net sales for the first nine months of 2002 increased 9.5% to $558.0 million from $509.6 million in 2001.

     Net sales in the Specialty Minerals segment increased 6.0% in the first nine months of 2002 to $384.1 million from $362.4 million in the same period in 2001. Worldwide net sales in the PCC product line grew 6.0% to $313.8 million for the first nine months of 2002 from $296.0 million in the same period of 2001. Net sales in the Processed Minerals product line increased 5.9% to $70.3 million in the first nine months of 2002 from $66.4 million in the prior year.

13

     On February 6, 2002, the Company purchased from the J.M. Huber Corporation of Edison, New Jersey a PCC manufacturing facility in Hermalle-sous-Huy, Belgium for approximately $10.2 million. The acquisition of this merchant PCC plant, which has the capacity to produce approximately 60,000 tons of PCC per year, will allow the Company to accelerate its European coating PCC program.

     On April 26, 2002, the Company acquired the assets of Thermo Radiometrie Oy and all of the outstanding shares of Thermo Radiometrie K.K. (collectively, "Radiometrie"). The purchase price was $1.4 million, which included acquisition costs and assumed liabilities. Radiometrie develops and manufactures a refractory lining monitoring system used to measure and monitor ceramic refractory linings of steel converters and ladles.

     Income from operations increased 9.1% to $64.0 million from $58.7 million in the first nine months of 2001. Excluding the prior year's restructuring charge, operating income increased 3.1% in the first nine months of 2002. The unfavorable leveraging of the sales growth to operating income occurred in the Refractories segment. Income from operations in the Specialty Minerals segment, excluding the prior year's restructuring charge, increased 8.3% to $47.8 million as compared with $44.1 million in the prior year and was 12.4% of its net sales. Income from operations in the Refractories segment, excluding the prior year's restructuring charge, decreased 9.6% to $16.3 million and was 9.4% of its net sales.

     Non-operating deductions decreased due to lower net interest expense as a result of decreased borrowings and lower interest rates.

     The Company's effective tax rate for 2002 was approximately 28.5%, compared with 29.5% in the prior year. The change in the effective tax rate reflects differences in the expected geographic mix of profit by country for the year.

     Net income for the first nine months increased 17.3% to $41.8 million from $35.6 million in 2001. Diluted earnings per common share increased 13.5% to $2.02 compared with $1.78 for the first nine months of 2001.

     Cash flows in the first nine months of 2002 were provided from operations and proceeds from stock option exercises and were applied principally to fund capital expenditures, to fund the aforementioned acquisitions, to repurchase common shares for treasury, and to repay short-term debt. Cash provided from operating activities amounted to $83.4 million in the first nine months of 2002 as compared with $72.3 million in the prior year.

     The Company has available approximately $115 million in uncommitted, short-term bank credit lines, of which $44 million was in use at September 29, 2002. The Company anticipates that capital expenditures, including acquisitions, for all of 2002 will approximate $70 million. The Company expects to meet its financing requirements from internally generated funds, its uncommitted bank credit lines and, where appropriate, project financing of certain satellite plants.

     The Securities and Exchange Commission encourages companies to disclose forward-looking information so that investors can better understand the companies' future prospects and make informed investment decisions. This report may contain forward-looking statements that set out anticipated results based on management's plans and assumptions. Words such as "expects," "plans," "anticipates," "will," and words and terms of similar substance used in connection with any discussion of future operating or financial performance identify these forward-looking statements.

     The Company cannot guarantee that the outcomes suggested in any forward-looking statement will be realized, although it believes it has been prudent in its plans and assumptions. Achievement of future results is subject to risks, uncertainties and inaccurate assumptions. Should known or unknown risks or uncertainties materialize, or should underlying assumptions prove inaccurate, actual results could vary materially from those anticipated, estimated or projected. Investors should bear this in mind as they consider forward-looking statements and should refer to the discussion of certain risks, uncertainties and assumptions under the heading "Cautionary Factors That May Affect Future Results" in Exhibit 99 to this Quarterly Report.

     In June 2001, the Financial Accounting Standards Board issued Statement of Financial Accounting Standard (SFAS) No. 143, "Accounting for Asset Retirement Obligations." SFAS No. 143, effective for fiscal years beginning after June 15, 2002, addresses financial accounting and reporting for obligations associated with the retirement of tangible and long-lived assets and the associated asset retirement costs. The Company is currently analyzing this statement and has not yet determined its impact on the consolidated financial statements.

     On July 30, 2002, the Financial Accounting Standards Board issued SFAS No. 146, "Accounting for Costs Associated with Exit or Disposal Activities." This standard requires companies to recognize costs associated with exit or disposal activities when they are incurred rather than at the date of a commitment to an exit or disposal plan. This statement is to be applied prospectively to exit or disposal activities initiated after December 31, 2002.

     The Company's discussion and analysis of its financial condition and results of operations is based upon the Company's consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities.

     On an on-going basis, the Company evaluates its estimates and assumptions, including those related to revenue recognition, allowance for doubtful accounts, valuation of inventories, valuation of long-lived assets, goodwill and other intangible assets, pension plan assumptions, income taxes, depreciation, income tax valuation allowances and litigation and environmental liabilities. The Company bases its estimates on historical experience and on various other assumptions that it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about carrying values of assets and liabilities that can not readily be determined from other sources. There can be no assurance that actual results will not differ from those estimates.

     Property, plant and equipment are amortized over their estimated useful lives. Useful lives are based on management's estimates of the period that the assets can generate revenue, which does not necessarily coincide with the remaining term of a customer's contractual obligation for use of those assets. Failure of a PCC customer to renew an agreement or continue to purchase PCC from the Company could result in an impairment of asset charge at such facility and/or a revision of the useful life and accelerated depreciation of such asset.

     See above under "Results of Operations -- Three Months Ended September 29, 2002 as Compared with Three Months Ended September 30, 2001" for a discussion of the Company's decision to shorten the periods over which existing satellite plants at International Paper Company paper mills are depreciated.

     For a detailed discussion on the application of these and other accounting policies, see the discussion of critical accounting policies in Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations," and the "Summary of Significant Accounting Policies" in the "Notes to the Consolidated Financial Statements" in the December 31, 2001 Annual Report on Form 10-K.

Market risk represents the risk of loss that may affect the Company's financial position, results of operations or cash flows due to adverse changes in market prices and rates. The Company is exposed to market risk because of changes in foreign currency exchange rates as measured against the U.S. dollar and changes in interest rates. It does not anticipate that near-term changes in exchange rates will have a material impact on its future earnings or cash flows. However, there can be no assurances that a sudden and significant decline in the value of foreign currencies would not have a material adverse effect on the Company's financial condition and results of operations. Approximately 33% of the Company's interest-bearing debt bears interest at variable rates; therefore the Company's results of operations would be affected by interest rate changes. However, an immediate 10 percent change in interest rates would not have a material effect on the Company's results of operations over the next fiscal year.

15

     The Company does not enter into derivatives or other financial instruments for trading or speculative purposes. When appropriate, the Company enters into derivative financial instruments, such as forward exchange contracts and interest rate swaps, to mitigate the impact of foreign exchange rate movements and interest rate movements on the Company's operating results. The counterparties are major financial institutions. Such forward exchange contracts and interest rate swaps would not subject the Company to additional risk from exchange rate or interest rate movements because gains and losses on these contracts would offset losses and gains on the assets, liabilities and transactions being hedged. The Company had open forward exchange contracts to purchase $0.5 million of foreign currencies as of September 29, 2002. These contracts mature on December 27, 2002. The fair value of these instruments was an asset of $18,000 at September 29, 2002. The Company entered into three-year interest rate swap agreements with a notional amount of $30 million that expire in January 2005. These agreements effectively convert a portion of the Company's floating-rate debt to a fixed-rate basis. The fair value of these instruments was a liability of $1.4 million at September 29, 2002.

     Within the 90 days prior to the date of this report, and under the supervision and with the participation of the Company's management, including the Chief Executive Officer and the Chief Financial Officer, the Company carried out an evaluation of the effectiveness of the design and operation of the Company's disclosure controls and procedures pursuant to Exchange Act Rule 13a-14. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the Company's disclosure controls and procedures are effective in timely alerting them to material information relating to the Company (including its consolidated subsidiaries) required to be included in the Company's periodic SEC filings.

     Subsequent to the date the Company carried out its evaluation, there have been no significant changes in the Company's internal controls or in other factors which could significantly affect these controls.

     On or about July 14, 2000, MTI, Specialty Minerals Inc. and Minteq International Inc. received from the Connecticut Department of Environmental Protection ("DEP") a proposed administrative consent order relating to the Canaan, Connecticut site, at which both Minteq and Specialty Minerals have operations. The proposed order would settle claims relating to an accidental discharge of machine oil alleged to have contained polychlorinated biphenyls at or above regulated levels. The Company's employees immediately took steps to contain and clean up the discharge and notified the Connecticut DEP and the U.S. EPA, as required by law. Investigations to define the nature and extent of contamination associated with historic use of polychlorinated biphenyls have been undertaken pursuant to administrative orders issued by the U.S. EPA and the Connecticut DEP. The proposed order also alleges certain violations of other environmental regulations, including violations of the Canaan site's existing permit for discharge of stormwater, and of regulations governing the management of underground storage tanks. The proposed order would require payment of a civil penalty of $341,000, remediation of certain conditions at the site, and other injunctive relief. MTI and the other respondents dispute many of the factual allegations forming the basis of the proposed order, and are contesting them vigorously. There can be no assurance, however, that the Company will be successful in doing so, and the amount of any civil penalty to be paid, and the cost of any remediation or other injunctive relief, remains uncertain.

     The Company and its subsidiaries are not party to any other pending legal proceedings, other than routine litigation incidental to their businesses.
