Interest Rate Risk We had unrestricted cash and cash equivalents of $230.5 million and $314.0 million as of June 30, 2026 and December 31, 2025, respectively. We maintain our cash and cash equivalents in deposit accounts and money market funds with various financial institutions. Due to the short-term nature of these instruments, we believe that we do not have any material exposure to changes in the fair value of these investments as a result of changes in interest rates. Increases or declines in interest rates would be expected to augment or reduce future interest income by an insignificant amount. We are exposed to risk related to changes in interest rates on our outstanding borrowings. Borrowings under our Credit Agreement bear interest at rates that are variable. Increases in the bank prime or SOFR rates would increase the interest rate on any future outstanding borrowings. Any debt we incur in the future may also bear interest at variable rates. ​ Our Notes have a fixed annual interest rate; therefore, we have no financial or economic interest exposure associated with changes in interest rates. However, the fair value of fixed rate debt instruments fluctuates when interest rates change. Additionally, the fair value of the Notes can be affected when the market price of our common stock fluctuates. We carry the Notes at principal value less unamortized issuance costs on our condensed consolidated balance sheets, and we present fair value for required disclosure purposes only. ​ Foreign Currency Exchange Risk Our revenues and expenses are primarily denominated in U.S. Dollars. For our foreign operations, the majority of our revenues and expenses are denominated in other currencies, such as the Canadian Dollar, Euro, British Pound, and Brazilian Real. Decreases in the relative value of the U.S. Dollar as compared to these currencies may negatively affect our revenues and other operating results as expressed in U.S. Dollars. For both the three and six months ended June 30, 2026, approximately 4% of our revenues were denominated in currencies other than U.S. Dollars. For the three and six months ended June 30, 2025, approximately 6% and 5%, respectively, of our revenues were denominated in currencies other than U.S. Dollars. 61 Table of Contents ​ We have experienced and will continue to experience fluctuations in our net income or loss as a result of transaction gains or losses related to revaluing certain current asset and current liability balances that are denominated in currencies other than the functional currency of the entities in which they are recorded. We have historically recognized immaterial amounts of foreign currency gains and losses in each of the periods presented. We may in the future hedge selected significant transactions denominated in currencies other than the U.S. dollar as we expand our international operations and our risk grows. 62 Table of Contents ​
