On March 31, 2025, the Company entered into a License and Assignment Agreement, or the Scithera License Agreement, with Scithera, Inc., or Scithera, a biotechnology company that focuses on antibody-based molecules.

Pursuant to the Scithera License Agreement, the Company licensed to Scithera the right to use certain assets in the Company’s antibody library to research, develop, and commercialize antibody-based molecules to certain targets. Additionally, the Company assigned to Scithera its agreement with NorthStar Medical Technologies, LLC for the development of radiopharmaceuticals for the treatment of cancer. The Company also agreed to make available to Scithera certain research materials useful for identifying, generating, and developing antibodies from antibody libraries to enable Scithera’s use of the assets licensed under the Scithera License Agreement.

Contingent upon Scithera’s achievement of specified funding events, Scithera was required to pay the Company $1.3 million as a non-refundable payment. In addition, Scithera may make additional future milestone payments of up to an aggregate of $41.25 million per target upon the achievement of certain milestone events, and potential royalty payments on net sales in the low- to mid-single digits.

As of the effective date of the agreement, the Company identified one performance obligation, which was the transfer of licenses to Scithera for the specified assets and all related materials and know-how. During the second quarter of 2025, Scithera achieved the specified funding event and made a non-refundable payment of $1.3 million to the Company. Upon notice of the achievement of such funding event, the Company re-assessed the transaction price to be $1.3 million, which was allocated to the single performance obligation. All remaining consideration under the agreement is variable consideration associated with the achievement of specified development milestones, and as a result, has been fully constrained (excluded) from the transaction price until such time that the Company concludes that it is probable that a significant reversal of previously recognized revenue will not occur. These estimates will be reassessed at each reporting period.

During the three and six months ended June 30, 2025, the Company completed its single performance obligation and recognized $1.3 million at the point in time upon the completion of the transfer of all licensed materials and know-how. No revenue was earned under the Scithera License Agreement during the three and six months ended June 30, 2026.
