We are subject to certain market risks arising from transactions in the normal course of business, principally risk associated with interest rate and foreign currency exchange rate fluctuations. Interest Rate Risk Cash, Cash Equivalents Restricted Cash and Investments—We are exposed to the risk of interest rate fluctuations on the interest income earned on our cash, cash equivalents, restricted cash and investments. A hypothetical one-percentage point increase or decrease in interest rates applicable to our cash, cash equivalents, restricted cash and investments outstanding at June 30, 2026 would increase or decrease interest income by approximately $1.3 million on an annual basis. Long-term Debt—Our interest rate risk relates primarily to the United States dollar SOFR-indexed borrowings. Based on our outstanding borrowings pursuant to the Amended and Restated Credit Agreement, interest is incurred at a floating per annum rate in an amount equal to the sum of (i) 6.95% (or 5.95% if the replacement rate is in effect) plus (ii) the greater of (x) the forward-looking term rate based on SOFR for a three month tenor (or the replacement rate, if applicable), and (y) 2.00% per annum. The remaining balance of unamortized debt issuance costs have been reflected as a direct reduction to the loan balance. Interest on the 2028 Convertible Notes is assessed at a fixed rate of 8.0% annually and therefore does not subject us to interest rate risk. Foreign Currency Exchange Risk We contract with organizations outside the United States at times. We may be subject to fluctuations in foreign currency exchange rates in connection with certain of these agreements. Transactions denominated in currencies other than the functional currency are recorded based on exchange rates at the time such transactions arise. Net foreign currency gains and losses did not have a material effect on our results of operations for the six months ended June 30, 2026.
