The Company invests in highly rated investment grade debt securities. As of June 30, 2025, all of the Company’s available-for-sale securities have final maturities of one year or less, except for five U.S. treasury securities classified as long-term with final maturities extending through November 15, 2026. The Company reviews the individual securities that have unrealized losses on a regular basis. The Company evaluates whether it has the intention to sell any of these investments and whether it is more likely than not that it will be required to sell any of them before recovery of the amortized cost basis. Neither of these criteria were met as of June 30, 2025 or December 31, 2024.

The Company additionally evaluates whether the decline in fair value of the securities below their amortized cost basis is related to credit losses or other factors. Based on this evaluation, the Company determined that the unrealized losses for its available-for-sale securities were primarily attributable to changes in interest rates and non-credit-related factors.

Accordingly, the Company determined that none of the unrealized losses were other-than-temporary, and that recognition of an impairment charge was not required as of June 30, 2025 or December 31, 2024. As of June 30, 2025, there were eight securities with an aggregate market value of $186.2 million that were in an unrealized loss position. The cumulative loss related to these securities was less than $0.1 million. None of the Company’s available-for-sale securities have been in an unrealized loss position for more than one year. No available-for-sale securities were sold during the six months ended June 30, 2025 or June 30, 2024.

See Note 5 for additional information regarding the fair value of the Company’s investments.
