[1] In August 2024, the Company purchased a $2.0 million non-marketable convertible promissory note from an unrelated third party (the “convertible note”). The convertible note bears a 5% interest rate annually and will mature in August 2026.

[2] The amortized cost of the Company’s investments in U.S. Government securities approximated their fair value due to their short-term maturities, and there have been no events or changes in circumstances that would have had a significant effect on the fair value of these securities in the periods presented. For the three and nine months ended September 30, 2025 and 2024, there were no material realized or unrealized gains or losses, either individually or in the aggregate.
