ITEM 4. MINE SAFETY DISCLOSURES
In the U.S., we lease silica quartz mine sites near our Tacoma, Washington facility and in Nevada that are being actively mined. We have contracted with a third-party mining company to perform the mining operations at these sites, including providing the labor and equipment for the mining work. We also maintain leases on various properties in Texas that would permit us to mine silica quartz and we own property in California which could be mined for silica. As of June 30, 2026, we are not mining at the Texas or California sites and have no immediate plans to do so.
As a mine operator in the U.S., we are required by Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”), and rules promulgated by the SEC implementing that section of the Dodd-Frank Act, to provide certain information concerning mine safety violations and other regulatory matters concerning the operation of our mines. During the three months ended June 30, 2026, we did not receive any notices, citations, orders, legal action or other communication from the U.S. Department of Labor’s Mine Safety and Health Administration that would necessitate additional disclosure under Section 1503(a) of the Dodd-Frank Act. Similarly, we have not experienced any mining-related fatalities in our mining operations. There are currently no pending legal actions before the Federal Mine Safety and Health Review Commission related to our mining operations.
