All marketable securities are classified as short-term. The Company regularly reviews its available-for-sale marketable securities in an unrealized loss position and evaluates the current expected credit loss by considering factors such as historical experience, market data, issuer-specific factors, and current economic conditions. As of June 30, 2026, the aggregate difference between the amortized cost and fair value of each security in an unrealized loss position was de minimis. Since any provision for expected credit losses for a security held is limited to the amount the fair value is less than its amortized cost, no allowance for expected credit loss was deemed necessary at June 30, 2026. As of June 30, 2026 and December 31, 2025, interest income receivable recorded as a component of prepaid expenses and other current assets on the condensed consolidated balance sheet were $0.2 million and de minimis, respectively.
