4. Revenue Recognition

Net Product Revenue

Net product revenue was approximately $18.5 million for the three months ended March 31, 2026 from the U.S. sales of IBTROZI. We began shipping IBTROZI to our U.S. customers in June 2025.

Collaboration and License Agreements Revenue

The Company enters into collaborative arrangements for the research and development, and commercialization of drug products and drug candidates. To date, these collaborative arrangements have included out-licensing of and options to out-license in-licensed compounds to other parties. These arrangements may include non-refundable upfront payments, contingent obligations for potential development, regulatory and commercial performance milestone payments, cost reimbursement arrangements, product supply and royalty payments.

In-Licensing Arrangements with Daiichi Sankyo Company Ltd. (“DS”)

The Company has in-licensed the rights to develop, manufacture and commercialize multiple development stage drug candidates globally or in specific territories. The development milestone payments are recognized when the achievement of the associated milestone becomes probable and estimable and have been expensed before regulatory approval has been obtained. In December 2024, a $2.0 million development milestone payment was capitalized as an intangible asset upon regulatory approval in China. We reached two milestones in 2024, and the resulting $6.0 million in development milestone payments owed were paid to DS in March 2025. In June 2025, upon regulatory approval in the U.S., an $8.0 million milestone payment was owed to DS under the arrangement. This milestone payment was paid in July 2025 and was capitalized as an intangible asset. We paid $3.0 million in February 2026 after converting SIGMA to a pivotal study, which was expensed to research and development.

Out-Licensing Arrangements

The Company's revenue related to its out-licensing collaborative agreements consist of product revenue, upfront license fees, royalty revenue and research and development services revenue from its collaboration agreements with Innovent Biologics Co. Ltd. (“Innovent”), Nippon Kayaku Co., Ltd. (“NK”), and Eisai Co., Ltd. (“Eisai”) for taletrectinib (also known as “AB-106”).

Collaboration and License Agreement with Innovent

In May 2021, AnHeart entered into an agreement with Innovent, granting Innovent a sub-licensable, royalty-bearing, exclusive right and license to commercialize AB-106 in the People's Republic of China and Taiwan (the “Innovent Territory”). AnHeart is responsible for funding ongoing clinical trials of AB-106, regulatory submissions after development with Innovent responsible for commercialization. Under the agreement, AnHeart received a non-refundable upfront cash payment, $12.0 million for achievement of certain regulatory approval milestones, and is eligible to receive up to $17.0 million upon achievement of additional regulatory milestones, up to $105.0 million upon achievement of commercial milestones, and tiered percentage royalties ranging from mid-teen to low-twenties on annual net sales of taletrectinib in the Innovent Territory subject to certain adjustments.

For the three months ended March 31, 2026, collaboration and license agreements revenue was comprised of research and development service revenue of $0.7 million, sales of products supply of $2.9 million and royalties of $1.4 million.

Collaboration and License Agreement with NK

In October 2023, AnHeart entered into an agreement with NK, granting NK a sub-licensable, royalty-bearing, exclusive right and license to commercialize AB-106 in Japan (the “NK Territory”). AnHeart is responsible for funding ongoing clinical trials of AB-106 in the NK Territory, with NK responsible for funding regulatory submissions in the NK Territory. The Company also granted NK a sub-licensable, royalty-bearing, exclusive right and license to research, develop and commercialize any new indications of AB-106 in the NK Territory (“NK New Indication Right”). Under the agreement, AnHeart received a non-refundable upfront cash payment of $40.0 million, $25.0 million for achievement of a regulatory milestone (“Regulatory Milestone Payment”), and is eligible to receive up to $35.0 million upon achievement of commercial milestones and a lower-mid double digit percentage royalty on net sales of taletrectinib in the NK Territory. In September 2025, taletrectinib was approved by Japan’s Ministry of Health, Labour, and Welfare. Since the regulatory approval has now been obtained, all remaining contract liability for research and development service from the initial upfront payment was recognized as revenue. In December 2025, upon receipt of the Regulatory Milestone Payment, the Company recognized $21.2 million in license revenue and $3.8 million in research and development service revenue.

The Company collaboration and license agreements revenue was comprised of research and development service revenue of $0.2 million, sales of products supply of $0.1 million, and royalties of $0.3 million for the three months ended March 31, 2026.

Collaboration and License Agreement with Eisai

On January 11, 2026, the Company entered into a License and Collaboration Agreement (the “License Agreement”) with Eisai. Pursuant to the License Agreement, the Company granted Eisai an exclusive license to develop and commercialize licensed products containing taletrectinib in the following territories: the European Union and all member states thereof, Albania, Andorra, Armenia, Azerbaijan, Belarus, Bosnia and Herzegovina, Georgia, Kosovo, Moldova, Monaco, Montenegro, North Macedonia, San Marino, Serbia, Switzerland, Ukraine, Vatican City, the United Kingdom, Russia, Turkey, Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, the United Arab Emirates, Israel, Jordan, Iran, Iraq, Libya, Lebanon, Egypt, Sudan, Morocco, Algeria, Tunisia, Australia, New Zealand, Canada, Singapore, Philippines, Indonesia, Thailand, Malaysia, Vietnam and India (collectively, the “Territory”).

In January 2026, upon receipt of the upfront payment, the Company recognized approximately $58.7 million in license revenue. For the three months ended March 31, 2026, the Company also recognized $0.2 million in research and development service revenue.

Contract assets and contract liabilities

When the Company satisfies its performance obligations by providing services to a customer before the customer pays consideration and before payment is due, the Company recognizes its rights to consideration as a contract asset.

The Company did not recognize any contract assets as of March 31, 2026.

When a customer pays consideration before the Company provides services, the Company records its obligation as a contract liability representing the transaction price allocated to the remaining performance obligations. The contract liabilities as of March 31, 2026 of $18.4 million are expected to be recognized as revenue as research and development services are provided over the next 3 years, with $8.6 million expected to be recognized within one year of the balance sheet date.

The Company recognized $0.7 million of revenue for the three months ended March 31, 2026 that was included in the contract liability balance at December 31, 2025.

The costs incurred to fulfill customer contracts were capitalized and amortized to cost of revenue on a systematic basis that is consistent with the transfer of research and development services to the customer to which the asset relates. For the three months ended March 31, 2026, $0.7 million of costs incurred to fulfill customer contracts were capitalized and expensed in the same period. There were no balances related to the costs incurred to fulfill customer contracts as of March 31, 2026.
