| License, Collaboration, and Success Payment Agreements | License, Collaboration and Success Payment Agreements Fred Hutch License Agreement - In 2018, the Company entered into a license agreement with Fred Hutchinson Cancer Center (“Fred Hutch”) that grants the Company a worldwide, sublicensable license under certain patent rights (exclusive) and certain technology (non-exclusive) to research, develop and commercialize products and processes for all fields of use utilizing chimeric antigen receptors (“CARs”) and/or T-cell receptors (“TCRs”), subject to certain exceptions. Collaboration and Success Payments - In 2018, the Company entered into a research and collaboration agreement with Fred Hutch (“Fred Hutch Collaboration Agreement”), pursuant to which it granted Fred Hutch rights to certain success payments. The potential payments for the Fred Hutch success payments are based on multiples of increased value ranging from 10 times to 50 times based on a comparison of the per share fair market value of the Company’s common stock relative to the original $1.83 per share issuance price of the Company’s Series A convertible preferred stock, which converted into an equal number of shares of the Company’s common stock in connection with the closing of the Company’s initial public offering (“IPO”). The aggregate success payments to Fred Hutch are not to exceed $200.0 million, which would only occur upon a 50 times increase in value relative to the original $1.83 per share issuance price of the Company’s Series A convertible preferred stock. Each threshold is associated with a success payment, ascending from $10.0 million at $18.29 per share to $200.0 million at $91.44 per share, payable if such threshold is reached during the measurement period. The term of the success payment agreement ends on the earlier to occur of (i) the nine-year anniversary of the date of the agreement and (ii) a change in control transaction. The following table summarizes the aggregate potential success payments, which are payable to Fred Hutch in cash or cash equivalents, or at the Company’s discretion, publicly-tradeable shares of the Company’s common stock:
The success payments will be owed if the per share fair value of the Company’s common stock on the contractually specified valuation measurement dates during the term of the success payment agreement equals or exceeds the above outlined multiples. The valuation measurement dates are triggered by the following events: the one-year anniversary of the Company’s IPO and each two-year anniversary of the Company’s IPO thereafter, the closing of a change in control transaction and the last day of the term of the success payment agreement, unless the term has ended due to the closing of a change of control transaction. As of March 31, 2025, no success payments have been incurred as the per share fair value of the Company’s common stock was below the price required for payment. The success payment liability was $0.1 million as of both March 31, 2025 and December 31, 2024, which is recognized in accrued liabilities and other current liabilities. With respect to the Fred Hutch Collaboration Agreement success payment obligations, the Company recognized success payment expense reversal of approximately zero for the three months ended March 31, 2025 and success payment expense of $0.4 million for the three months ended March 31, 2024, which are recognized in other income, net. Stanford License Agreement - In 2019, the Company entered into a license agreement with The Board of Trustees of the Leland Stanford Junior University (“Stanford”) to license specified patent rights. Collaboration and Success Payments - In October 2020, the Company entered into a research and collaboration agreement with Stanford (“Stanford Collaboration Agreement”), pursuant to which it granted Stanford rights to certain success payments. The potential payments for the Stanford Collaboration Agreement success payments are based on multiples of increased value ranging from 10 times to 50 times based on a comparison of the per share fair market value of the Company’s common stock relative to the original $1.83 per share issuance price of the Company’s Series A convertible preferred stock, which converted into an equal number of shares of the Company’s common stock in connection with the closing of the Company’s IPO. The aggregate success payments to Stanford are not to exceed $200.0 million, which would only occur upon a 50 times increase in value relative to the original $1.83 per share issuance price of the Company’s Series A convertible preferred stock. Each threshold is associated with a success payment, ascending from $10.0 million at $18.29 per share to $200.0 million at $91.44 per share, payable if such threshold is reached during the measurement period. The term of each success payment agreement ends on the earlier to occur of (i) the nine-year anniversary of the date of the agreement and (ii) a change in control transaction. The following table summarizes the aggregate potential success payments, which are payable to Stanford in cash or cash equivalents, or at the Company’s discretion, publicly-tradeable shares of the Company’s common stock:
The success payments will be owed if the per share fair value of the Company’s common stock on the contractually specified valuation measurement dates during the term of the success payment agreement equals or exceeds the above outlined multiples. The valuation measurement dates are triggered by the following events: the one-year anniversary of the Company’s IPO and each two-year anniversary of the Company’s IPO thereafter, the closing of a change in control transaction and the last day of the term of the success payment agreement, unless the term has ended due to the closing of a change of control transaction. As of March 31, 2025, no success payments have been incurred as the per share fair value of the Company’s common stock was below the price required for payment. The success payment liability is estimated at the fair value at inception and at each subsequent reporting period and the expense is accreted over the service period of the Stanford Collaboration Agreement as research and development expense through September 2024. As of October 2024, the Company’s associated success payment liability was fully accreted to fair value as Stanford had provided the requisite service obligation to earn the potential success payment consideration. The success payment liability was $0.2 million and $0.3 million as of March 31, 2025 and December 31, 2024, respectively, which is recognized in accrued liabilities and other current liabilities. With respect to the Stanford Collaboration Agreement success payment obligations, the Company recognized success payment expense reversal of $0.1 million for the three months ended March 31, 2025 and success payment expense of $0.5 million for the three months ended March 31, 2024, which are recognized in other income, net and research and development expense, respectively.
