Marketable securities classified as current as of June 30, 2026 and December 31, 2025 had contractual maturities of one year or less from the purchase date.

As of June 30, 2026 and December 31, 2025, no significant facts or circumstances were present to indicate a deterioration in the creditworthiness of the issuers of the marketable securities, and the Company has no requirement or intention to sell these securities before maturity or recovery of their amortized cost basis. The Company considered the current and expected future economic and market conditions and determined that its marketable securities were not significantly impacted. For all marketable securities with a fair value less than its amortized cost basis, the Company determined the decline in fair value below amortized cost basis to be immaterial and non-credit related, and therefore no allowance for expected credit losses was recorded for the three and six months ended June 30, 2026 and 2025.
