We are exposed to market risk from changes in interest rates and changes in foreign currency exchange rates. A discussion of our primary market risk exposure in financial instruments is presented below. Interest Rate Risk We are primarily exposed to interest rate risk through our Credit Facility, which is subject to variable interest rates as determined by the debt agreement. At June 30, 2026, we had no borrowings under our Credit Facility. Foreign Currency Risk Our principal foreign operations are currently conducted in the U.K., which contributed approximately 12% of our consolidated revenues for the first half of 2026. We have foreign currency exchange risks associated with these operations, which are conducted principally in British pounds. Historically, we have not used off-balance sheet financial hedging instruments to manage foreign currency risks when we enter into a transaction denominated in a currency other than our local currencies.

In the ordinary course of conducting our business, we become involved in litigation and other claims from private party actions, as well as judicial and administrative proceedings involving governmental authorities at the federal, state, and local levels. In addition, in connection with the Sale Transaction, we have indemnified the Purchaser for certain pre-closing contingencies of the Fluids Systems business. While the outcome of litigation or other proceedings against us, including pre-closing contingencies of the Fluids Systems business, cannot be predicted with certainty, management does not expect that any loss resulting from such litigation or other proceedings, in excess of any amounts accrued or covered by insurance, will have a material adverse impact on our consolidated financial statements.

There have been no material changes during the period ended June 30, 2026 to our “Risk Factors” as discussed in Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2025. 22
