Minerals Technologies (MTX) Earnings: Q3 2026 Results

The quarter ended October 4, 2026 and Minerals Technologies published the results on October 29, 2026. Revenue and diluted EPS are shown against Q3 2025, the same quarter a year earlier, which takes seasonal swings out of the comparison. Minerals Technologies reports EPS two ways: GAAP, under the accounting rules every US filer follows, and excluding special items, which leaves out items the company considers outside its operating results. The release reconciles the two, and when they diverge, the reconciliation says why.

• Minerals Technologies uses a fiscal calendar: Q3 2026 ended October 4, 2026 and Q3 2025 ended September 28, 2025, both 91 days. The 2026 nine-month period had 277 days against 271.
• Q2 2026 GAAP EPS of $(5.90) reflects a $290 million charge to increase the reserve for talc-related claims after the company filed a Plan of Reorganization in the Chapter 11 cases of its subsidiary BMI Oldco Inc.

How Minerals Technologies splits revenue in its own release, under its own labels, for Q3 2026 against Q3 2025. Indented lines are parts of the line above them.

• Minerals Technologies's Consumer & Specialties revenue was $278 million in Q3 2026, flat on $277 million in Q3 2025, 50% of total revenue.
• Minerals Technologies's Engineered Solutions revenue was $277 million in Q3 2026, up 9% from $255 million in Q3 2025, 50% of total revenue.

Segment lines are the figures writers cite most often, because they show where the growth in a quarter came from. Companies redraw their segments from time to time and restate the prior year to match, so a year-ago figure here can differ from the one printed a year ago. When that has happened, the note above says so.

From the earnings release

Minerals Technologies gives no numeric revenue or earnings outlook in its release. The only outlook is this sentence from the CEO.

In its Q3 2026 release (Douglas T. Dietrich, Chairman and CEO), Minerals Technologies said:

“Our sales growth continued in the third quarter, and we remain on track to achieve mid-single-digit revenue growth for the full year”

Each quarter keeps its own page with the figures as reported, so a link to one stays pointed at the same numbers after the next report.

• Q3 2026 (this page), reported Oct 29, 2026

Minerals Technologies had net sales of $554.9 million in Q3 2026, up 4% from $532.4 million a year earlier and 1% higher than the previous quarter. Sales split almost evenly between its two segments: Consumer & Specialties at $278.1 million and Engineered Solutions at $276.8 million. (Minerals Technologies Q3 2026 release (8-K Exhibit 99.1), Oct 29, 2026)

Consumer & Specialties sells mineral-to-market products such as cat litter, edible oil and renewable fuel purification, animal health and agriculture through Household & Personal Care ($130.5 million), and mineral additives for paper and packaging, food and pharmaceuticals, sealants, paints and residential construction through Specialty Additives ($147.6 million, flat with a year earlier). Household & Personal Care rose 6% sequentially on higher cat litter volumes in North America. (Minerals Technologies Q3 2026 release (8-K Exhibit 99.1), Oct 29, 2026)

Engineered Solutions drove the growth, up 9%. High-Temperature Technologies, which serves foundry and steel customers, grew 7% to $192.3 million on higher sales to steel and foundry customers, and Environmental & Infrastructure grew 11% to $84.5 million on environmental lining and remediation products, building materials and infrastructure drilling. (Minerals Technologies Q3 2026 release (8-K Exhibit 99.1), Oct 29, 2026)

United States sales were $287.7 million, 52% of the total, and international sales $267.2 million. Much of Minerals Technologies' paper and packaging business runs through satellite plants it owns and operates next to customers' mills, usually under long-term contracts. (Minerals Technologies Q3 2026 release (8-K Exhibit 99.1), Oct 29, 2026; Minerals Technologies Form 10-K, 2025, Feb 20, 2026)

Minerals Technologies earned GAAP diluted EPS of $1.37 in Q3 2026, the same as a year earlier, and $1.53 excluding special items, down from $1.55. The only special item in the quarter was $6.7 million of litigation expenses tied to the bankruptcy of its former talc subsidiary BMI Oldco Inc. and lawsuits over talc products it sold, which net of a $1.6 million tax effect accounts for the gap. (Minerals Technologies Q3 2026 release (8-K Exhibit 99.1), Oct 29, 2026)

Profit fell in Consumer & Specialties: segment operating income was $24.8 million, down 34%, because higher energy, transportation and raw material costs were not fully recovered within the quarter given the timing of contractual pricing adjustments. Engineered Solutions earned $48.7 million, a 17.6% margin. Consolidated operating margin excluding special items was 12.9%, down from 14.7%. (Minerals Technologies Q3 2026 release (8-K Exhibit 99.1), Oct 29, 2026)

The tax provision was $12.2 million on pre-tax income of $53.0 million. Diluted shares were 31.2 million, against 31.3 million a year earlier. On October 21, 2026 the board raised the quarterly dividend by 8% to $0.13 per share. (Minerals Technologies Q3 2026 release (8-K Exhibit 99.1), Oct 29, 2026)

Diluted EPS divides net income by the weighted average number of shares outstanding in the quarter, plus the shares that options and other equity awards could add. Buybacks shrink that count and lift EPS for the same profit; share issuance and stock awards enlarge it.

Minerals Technologies does not publish a numeric revenue or EPS outlook in its release. CEO Douglas Dietrich said the company remains on track to achieve mid-single-digit revenue growth for the full year; nine-month sales were $1,650.2 million, up 6%. (Minerals Technologies Q3 2026 release (8-K Exhibit 99.1), Oct 29, 2026)

At its September 22, 2026 Investor Day, Minerals Technologies introduced a process to produce high-purity calcium metal for U.S. heavy rare earth metallization and a way to extract minerals from steel slag, and estimated the two could create over $200 million in revenue over the next five years. On October 13, 2026 it issued $400 million of 7.5 percent senior notes due 2032 to repay notes due in 2028. (Minerals Technologies Q3 2026 release (8-K Exhibit 99.1), Oct 29, 2026)

A consensus figure is the average of the models published by the analysts who cover Minerals Technologies, collected by a data provider and revised up to the day of the report. A quarter that lands above it says how expectations were set as much as how the business did, and the share price on the day also reflects the guidance and the lines no consensus covers.

The consensus figures on this page are Yahoo Finance's, as pulled on the date shown. Each comes with the number of analysts behind it; the smaller that number, the more one revised estimate can move the average.

The figures below are the ones Minerals Technologies's own release and filings put weight on for Q3 2026, with the latest reported value for each.

What the quarter means for a holding is a separate question from what it reported. The case for and against owning MTX is on is MTX a buy or a sell?, what analysts expect next is on the MTX forecast, and what the company does is on the Minerals Technologies (MTX) stock page.

Every number on this page can be traced to a document Minerals Technologies published. Checking one takes a couple of minutes, and it is worth doing before you quote a figure anywhere.

• The results release is the document linked in the source line above. Companies publish it on their investor relations site at the moment results go out, and it carries the headline tables: revenue, operating income, net income and EPS for the quarter and the year-ago quarter.
• The same release is filed with the SEC as Exhibit 99.1 to a Form 8-K under Item 2.02, usually on the day of the report. The SEC copy does not change after the fact, which makes it the safer thing to link when you cite a number.
• The quarterly report (Form 10-Q) follows within a few weeks and carries the full financial statements, the segment note and management's discussion of what changed. The fourth quarter is covered by the annual report (Form 10-K) instead.
• Restated comparisons are flagged in the notes on this page. When a company redraws its segments or changes how it adjusts EPS, it restates the year-ago column, so the year-ago figure in a new release can differ from the one printed a year ago. This page always uses the comparison in the newer release, because that is the like-for-like one.
