NEW YORK, February 2, 2023 – Minerals Technologies Inc. (NYSE: MTX) (“MTI” or “the Company”) today reported diluted earnings per share of $0.67, excluding special items, for the fourth quarter ended December 31, 2022, compared with $1.25 in the prior year. Reported diluted earnings per share were $0.62 compared with $1.23 in the prior year.

For the full year 2022, the Company reported earnings per share of $4.88, excluding special items, compared with $5.02 in the prior year. Reported earnings per share were $3.73 compared with $4.86 for the full year 2021.

“We had a challenging finish to an otherwise strong year, with several acute factors impacting our fourth quarter results. Inflationary costs in Europe were higher, and the combination of severe weather in the U.S. and COVID-related shutdowns in China significantly hampered our operations and shipments in the quarter,” says Douglas T. Dietrich, Chairman and CEO. “Our teams navigated through significant challenges throughout the year to deliver solid performance in 2022. We continued to advance our growth strategy, we more than offset historic levels of inflation with price increases, and we continued to balance our portfolio for more stable growth with the acquisition of Concept Pet. Looking ahead, the company is well-positioned to continue to deliver higher levels of profitable growth.”

Fourth Quarter 2022

Worldwide net sales were $507.6 million, up 6 percent versus the prior year. On a constant currency basis, sales grew 13 percent versus the prior year, as foreign exchange had an unfavorable impact of $30 million.

Reported operating income was $43.6 million. Operating income excluding special items was $44.0 million and represented 8.7 percent of sales. Operating income and margins in the fourth quarter were impacted by higher inflationary costs, particularly freight and energy associated with the European pet care business. In addition, COVID-related shutdowns in China and severe weather conditions in the western U.S. affected production, shipping, and operating costs at several facilities.

Segment Information

Performance Materials segment sales were $265.6 million in the fourth quarter, up 4 percent versus the prior year. On a constant currency basis, sales were up 11 percent from the prior year, as foreign exchange had an unfavorable impact of $18 million.

Household, Personal Care & Specialty Products sales increased 8 percent versus the prior year primarily driven by the acquisition of Concept Pet and continued strong demand for consumer-oriented products. Metalcasting sales decreased 5 percent versus the prior year as strength in North America was offset by COVID-related shutdowns in China. Environmental Products sales grew 18 percent from the prior year on strength in remediation, wastewater, and filtration activities. Building Materials sales were down 13 percent versus the prior year, primarily due to lower construction activity levels in Europe.

Segment operating income excluding special items was $19.0 million and operating margin was 7.2 percent of sales. Operating income and margins were impacted by higher inflationary costs, primarily related to sea freight and energy rates incurred by the European pet care business on bulk bentonite transfers from Turkey to the Netherlands. While sea freight and energy rates moderated at the end of the year, this business incurred significant inflation in the fourth quarter through the sale of this high-cost inventory. Margins for the segment were also impacted by COVID-related shutdowns in China and severe weather in the western U.S.

The Performance Materials segment provides a wide range of bentonite-based and synthetic materials for consumer-oriented and industrial markets and for non-residential construction, environmental remediation, and infrastructure projects worldwide.

Specialty Minerals segment sales were $155.1 million in the fourth quarter, 10 percent above the prior year. On a constant currency basis, sales were up 14 percent, as foreign exchange had an unfavorable impact of $7 million.

Refractories segment sales were $86.9 million in the fourth quarter, up 10 percent from the prior year. On a constant currency basis, sales were up 17 percent, as foreign exchange had an unfavorable impact of $6 million. Refractories segment sales increased primarily due to the continued ramp-up of new business volumes and higher pricing to cover inflationary cost increases.

Segment operating income was $12.5 million and represented 14.4 percent of sales. The Refractories segment provides products and services primarily to the worldwide steel industry.

Full Year 2022

Household, Personal Care & Specialty Products sales increased 22 percent, primarily due to continued strong demand for consumer-oriented products and the acquisition of Concept Pet. Metalcasting sales grew 5 percent as strength in North America and the rest of the world offset weakness in China due to COVID-related restrictions and shutdowns. Environmental Products sales grew 28 percent on strength in remediation, wastewater, and filtration activity. Building Materials sales were 2 percent lower than the prior year.

Segment operating income excluding special items was $130.8 million, up 4 percent versus the prior year, and operating margin was 11.6 percent of sales.

Refractories segment sales were $349.4 million, 15 percent higher than the prior year. On a constant currency basis, sales grew 21 percent, as foreign exchange had an unfavorable impact of $19 million.

Segment operating income was a record at $57.6 million and represented 16.5 percent of sales. Sales and operating income benefited from strong operating performance and new business development.
