&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● Earnings per share of $1.17, or $1.38 excluding special items, representing a 21% increase over the prior year

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● 11% sales growth over prior year and 5% over prior quarter

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● Strong sales growth in both segments, momentum continuing in Q2

NEW YORK, April 30, 2026 (GLOBE NEWSWIRE) -- Minerals Technologies Inc. (NYSE: MTX) ("MTI"), a leading, technology-driven specialty minerals company, today reported earnings per share for the first quarter ended April 5, 2026, of $1.17, or $1.38 excluding special items, representing a 21 percent increase over the prior year.

"In the first quarter, our sales grew by double digits across multiple businesses, underscoring the momentum we have built in recent quarters. Supported by our innovation pipeline and recent growth investments, we expect this momentum to continue through the year," said Douglas T. Dietrich, MTI's Chairman and Chief Executive Officer. "Recent geopolitical events presented new challenges; however, consistent with our track record, our teams moved quickly to make the necessary adjustments to navigate higher global energy costs."

**First Quarter 2026 Consolidated Results**

In the first quarter, MTI's worldwide net sales were $547 million, up 11 percent over the prior year, primarily driven by volume growth across both segments. Foreign exchange had a favorable impact on sales of $17 million.

Reported operating income was $59 million, or $68 million excluding special items, up 7 percent over the prior year. Reported operating margin was 10.7 percent of sales, or 12.3 percent excluding special items.

**First Quarter 2026 Segment Results**

**Consumer & Specialties** segment sales were $297 million, up 8 percent sequentially and 11 percent over prior year. Sales in the Household & Personal Care product line were $142 million, up 7 percent sequentially and 16 percent over the prior year, driven by cat litter, animal health, fabric care, and edible oil and renewable fuel purification. Sales in the Specialty Additives product line were $154 million, up 9 percent sequentially and 6 percent over the prior year, primarily driven by higher sales to paper and packaging customers.

Segment reported operating income was $33 million, up 18 percent over the prior year or 8 percent excluding special items.

It includes two product lines: Household & Personal Care, which delivers mineral-to-market products for improved performance and enhanced consumer experiences in end markets including cat litter, household and personal care, edible oil and renewable fuel purification, animal health, and agriculture; and Specialty Additives, which offers mineral-based technologies for improved functionality in end markets including paper and packaging, food and pharmaceuticals, sealants and adhesives, paints and coatings, and residential construction.

**Engineered Solutions**segment sales were $250 million, up 2 percent sequentially and 12 percent over the prior year. Sales in the High-Temperature Technologies product line were $183 million, up 3 percent sequentially and 8 percent over the prior year, driven by continued higher sales to steel customers and supported by a stable performance in our foundry business. In the Environmental & Infrastructure product line, sales were $67 million, flat sequentially and up 24 percent over the prior year, driven by stronger sales related to large-scale project activity, infrastructure drilling, and offshore water treatment.

Segment reported operating income was $39 million, up 17 percent over prior year or 14 percent excluding special items.

MTI's Engineered Solutions segment provides advanced technologies and solutions designed to improve customers' manufacturing processes and projects. It includes two product lines: High-Temperature Technologies, which delivers mineral-based blends, technologies, and systems that solve complex challenges in the foundry, steel, and other high-temperature processing industries; and Environmental & Infrastructure, which offers solutions for water treatment, fluid management, building materials, and environmental, remediation, and infrastructure-related projects.

**NOTES TO CONDENSED CONSOLIDATED STATEMENTS OF INCOME (LOSS)**

1) For comparative purposes, the quarterly periods ended April 5, 2026, December 31, 2025, and March 30, 2025 consisted of 95 days, 94 days, and 89 days, respectively.

2) To supplement the Company's consolidated financial statements presented in accordance with GAAP, the following is a presentation of the Company's non-GAAP earnings per share, excluding special items, for the quarterly periods ended April 5, 2026, December 31, 2025 and March 30, 2025, and a reconciliation to reported earnings per share for such periods.

In the first quarter of 2025, the Company recorded a $215 million provision to establish a reserve for estimated costs to fund a trust to resolve all current and future talc-related settlements as well as fund the bankruptcy of BMI Oldco Inc.'s (f/k/a Barretts Minerals Inc.) ("Oldco") and Barretts Ventures Texas LLC, and related litigation costs. Included in this provision is $30 million of additional debtor-in-possession financing by Minerals Technologies Investments LLC to the Debtors, which was committed in Q2 2025. In addition, the Company initiated a cost savings program and recorded a $5.5 million charge relating to severance and other costs in the first quarter of 2025. The Company incurred litigation and settlement expenses of $8.8 million, $5.1 million, and $2.8 million for the quarterly periods ending April 5, 2026, December 31, 2025, and March 30, 2025, respectively, in connection with the bankruptcy of Oldco and lawsuits related to talc products sold by Oldco.

In the fourth quarter of 2025, the Company recorded $3.7 million of restructuring and other items primarily related to the write-down of assets and other charges relating to consolidated and shut-down facilities.

In the fourth quarter of 2025, the Company recorded a $4.3 million net gain related to the sale of our chromite mine in South Africa.

3) Free cash flow is defined as cash flow from operations less capital expenditures. The following is a presentation of the Company's non-GAAP free cash flow for the quarterly periods ended April 5, 2026, December 31, 2025, and March 30, 2025 and a reconciliation to cash flow from operations for such periods. The Company's management believes this non-GAAP measure provides meaningful supplemental information as management uses this measure to evaluate the Company's ability to maintain capital assets, satisfy current and future obligations, repurchase stock, pay dividends and fund future business opportunities. Free cash flow is not a measure of cash available for discretionary expenditures since the Company has certain non-discretionary obligations such as debt service that are not deducted from the measure. The Company's definition of free cash flow may not be comparable to similarly titled measures reported by other companies.

To supplement the Company's consolidated financial statements presented in accordance with GAAP, the following is a presentation of the Company's non-GAAP operating income, excluding special items (set forth in the above table), for the quarterly periods ended April 5, 2026, December 31, 2025 and March 30, 2025, constituting a reconciliation to GAAP operating income (loss) set forth above. The Company's management believe these non-GAAP measures provide meaningful supplemental information regarding its performance as inclusion of such special items are not indicative of ongoing operating results and thereby affect the comparability of results between periods. The Company believes inclusion of these non-GAAP measures also provides consistency in its financial reporting and facilitates investors' understanding of historic operating trends.
