“Building on the momentum from previous quarters, the MTI team delivered second quarter sales growth, margin expansion, and the highest earnings per share in our company’s history,” said Douglas T. Dietrich, Chairman and Chief Executive Officer. “Continued robust demand across our end markets, strong operational execution while navigating a dynamic supply chain environment, and improving activity in our project-oriented businesses enabled MTI to deliver these results. In addition, we continued to make progress on our growth initiatives globally and improved our balance sheet while delivering strong free cash flow.”

Mr. Dietrich added, “We were also excited to close on the highly complementary acquisition of Normerica, which significantly strengthens our position in the North America cat litter market. MTI is now one of the largest vertically integrated packaged private label pet litter providers globally with a strong foundation in product development and innovation. We look forward to working with the Normerica team on a seamless integration.”

Second Quarter 2021

Worldwide net sales were $455.6 million, 28 percent higher than the prior year and 1 percent higher sequentially on continued strong demand across the majority of end markets. Foreign exchange had a favorable impact on sales of approximately $15 million, or 4 percentage points, versus the prior year.

Operating income was $63.7 million, or $64.1 million excluding special items. Operating income excluding special items grew 53 percent versus the prior year and 9 percent versus the first quarter. Operating Margin was 14.1 percent excluding special items, compared to 11.8 percent in the prior year and 13.0 percent in the first quarter.

Cash flow from operations was $67.1 million compared to $63.8 million in the prior year. First half 2021 cash flow from operations was $118.0 million compared with $94.1 million in the prior year, a 25 percent improvement. Capital expenditures were $22.2 million in the second quarter versus $15.0 million in the prior year, as the company continued to invest in high-return organic growth opportunities.

Segment Information

Performance Materials segment sales were $238.4 million in the second quarter, 24 percent higher than the prior year and 3 percent higher sequentially.

Metalcasting sales were 52 percent higher than the prior year and 1 percent lower sequentially as foundry demand remained strong in North America and China. Household, Personal Care & Specialty Products sales were 17 percent above the prior year and 6 percent lower sequentially, primarily due to seasonally lower pet care sales. Environmental Products sales grew 6 percent versus the prior year and 53 percent sequentially as demand for environmental lining systems, remediation, and wastewater treatment started to improve. Building Materials sales grew 17 percent versus the prior year and 12 percent sequentially on higher levels of project activity, particularly in North America.

Operating income for the segment was $34.7 million, 55 percent above the prior year and 16 percent higher sequentially. Operating margin was 14.6 percent of sales versus 11.7 percent in the prior year and 12.9 percent in the first quarter as pricing actions and productivity more than offset inflationary cost pressures. In addition, higher volumes and increased project activity drove incremental margin improvement.

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

Specialty Minerals segment sales, which consist of the Precipitated Calcium Carbonate (PCC) and Processed Minerals product lines, were $142.7 million in the second quarter, 30 percent higher than the prior year and 3 percent lower sequentially.

PCC sales grew 30 percent versus the prior year on recovering Paper PCC demand and the continued ramp-up of three new satellite plants, as well as higher SPCC demand from automotive, construction, and consumer end markets. PCC sales were 5 percent lower sequentially, primarily due to typical seasonal paper mill maintenance outages in North America and temporary customer outages in India related to COVID-19. PCC is used in paper and packaging, automotive and construction sealants, and the food and pharmaceutical industries.

Processed Minerals sales grew 31 percent versus the prior year and 2 percent sequentially on continued strength in residential construction and consumer end markets. Processed Minerals products are used in the building materials, polymers, ceramics, consumer products, paints and coatings, glass, and other manufacturing industries.

Segment operating income was $20.0 million, 31 percent higher than the prior year excluding special items and 5 percent lower sequentially. Operating margin was 14.0 percent of sales and was impacted by the timing of price increases relative to higher energy and raw material costs.

Refractories segment sales were $74.5 million in the second quarter, 33 percent higher than the prior year and 1 percent higher sequentially on strong end market demand.

Segment operating income was $11.7 million, 98 percent higher than the prior year and 3 percent lower sequentially. Operating margin remained strong at 15.7 percent of sales. The Refractories segment provides products and services primarily to the worldwide steel industry.

Acquisition of Normerica

On July 26, 2021, MTI completed the acquisition of Normerica, a leading supplier of premium pet care products in North America.

Normerica, a privately held company, was established in 1992 and is headquartered in Toronto, Canada. Normerica has grown significantly since its inception, becoming a leading North American producer and supplier of branded and private label pet care products to a large customer base. Its product portfolio consists primarily of bentonite-based cat litter products which are supplied from a network of strategically located manufacturing facilities in Canada and the United States. Normerica employs approximately 320 people and generated revenue of approximately $140 million in 2020.

MTI is financing the acquisition through a combination of cash on hand and its current credit facilities. The purchase of Normerica is expected to be accretive to MTI’s earnings per share in 2021. Normerica’s financial results will be reported in the Household, Personal Care & Specialty Products business within MTI’s Performance Materials segment.

Accordingly, in Q1 2021, in order to support MTI's key growth initiatives and more closely align complementary technologies, processes and capabilities, the Company reorganized the management structure for its Energy Services and Performance Materials operating segments to better reflect the way performance is evaluated and resources are allocated. As a result, Energy Services was combined into Environmental Products under the Performance Materials operating segment. Presented below are the restated financial results, by product line, for each of the quarters and full year 2020 of this operating segment to conform to the current management structure.

	5	)	Free cash flow is defined as cash flow from continuing operations less capital expenditures. The following is a presentation of the Company's non-GAAP free cash flow for the quarterly periods ended July 4, 2021, April 4, 2021 and June 28, 2020 and the six month periods ended July 4, 2021 and June 28, 2020 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.
