Interest Rate Risk
We are exposed to market risks in the ordinary course of our business. These risks primarily relate to interest rate fluctuations. As of June 30, 2026, we had cash and cash equivalents of $62.1 million, consisting of bank deposits and money market funds. We had marketable investment securities of $204.7 million, primarily invested in U.S. government securities. Due to the nature of these instruments, we believe our exposure to interest rate risk is not material.
As of June 30, 2026, we had outstanding term debt of $10.1 million under a term loan that bears interest at a floating rate based on the WSJ Prime Rate, subject to an interest rate floor of 6.00%, which exposes us to interest rate risk.
A hypothetical 10% change in interest rates during any of the periods presented would not have had a material impact on our financial statements.
Foreign Currency Risk
We are exposed to foreign currency exchange rate risk primarily related to a loan receivable and certain equity securities denominated in Swedish Krona (“SEK”). As of June 30, 2026, this loan had a principal balance of SEK 20 million and bears interest at a rate of 2.00% plus the three-month Stockholm Interbank Offered Rate. We do not currently hedge our foreign currency exposure. A hypothetical 10% change in foreign currency exchange rates

would increase or decrease the value of our foreign currency-denominated assets by approximately $1.0 million, which we do not consider material to our financial statements.
Inflation Risk
Our exposure to inflationary pressures is primarily in personnel and related costs. The extent of any future impacts from inflation on our business and our results of operations will depend on the duration and severity of inflationary trends, which we are unable to predict. If inflationary pressures persist or increase, our operating expenses may rise and we may utilize our capital resources sooner than expected. Additionally, due to the reimbursement environment in which we operate, our payors may be unwilling or unable to adjust reimbursement rates to offset inflationary cost increases.
Equity Price Risk
As of June 30, 2026, we held equity securities with a total fair value of $6.8 million. A hypothetical 10% decrease in the market price of these securities would result in an approximate $0.7 million decrease in fair value. These securities are subject to market-related risks that could materially impact their value.
