Investments, Debt and Equity Securities [Abstract] |
Investments in Non-Marketable Securities | Investments in Non-Marketable Securities Non-Marketable Equity Securities Our non-marketable equity securities are investments in privately held companies without readily determinable market value and primarily relate to our investments in seqWell Inc. (“seqWell”) and other investments in non-marketable equity securities. These investments are accounted for under the measurement alternative and are measured at cost minus impairment, if any, plus or minus changes resulting from observable price changes for identical or similar securities of the same issuer. Non-marketable equity securities are measured at fair value on a non-recurring basis and classified within Level 2 in the fair value hierarchy when we estimate the fair value of these investments using the observable transaction price paid by third party investors for the same or similar security of the same issuers. The fair value of non-marketable equity securities are classified within Level 3 when we estimate fair value using unobservable inputs such as when we remeasure due to impairment and we use discount rates, market data of comparable companies, and rights and obligations of the securities the Company holds, among others. We adjust the carrying value of non-marketable equity securities which have been remeasured during the period and recognize resulting gains or losses as a component of interest and other expense, net in the unaudited condensed consolidated statements of operations. There was no remeasurement event for our investments in non-marketable equity securities that occurred during the three and nine months ended September 30, 2025. For the three and nine months ended September 30, 2024, we recognized an impairment charge of $3.9 million which is presented within interest and other expense, net in the condensed consolidated statements of operations. This adjustment is related to the write-down of our investment in Molecular Assemblies, Inc. (“MAI”) to its related fair value as determined based on valuation methods using the latest observed transaction price of MAI’s preferred stock securities to be issued during the fourth quarter of 2024 and adjusted for the rights and obligations of the preferred stock securities the Company holds. There was no remeasurement event for our other investments in non-marketable equity securities that occurred during the three and nine months ended September 30, 2024. We recognized no realized gains or losses during the three and nine months ended September 30, 2025 and 2024. The following table presents the carrying value of our non-marketable equity securities (in thousands):
