Evaluation and Collaborative Arrangements	6. Evaluation, Collaboration and License, and Collaborative Arrangements Chugai Collaboration and License Agreement In October 2025, the Company entered into a Collaboration and License Agreement (the “Chugai Collaboration and License Agreement”) with Chugai Pharmaceutical Co., Ltd. (“Chugai”). Under the Chugai Collaboration and License Agreement, the Company and Chugai will collaborate to develop, manufacture, seek regulatory approvals for and, if approved, commercialize a product (the “Chugai Product” or “RT-117”) combining Chugai’s antibody (the “Compound”), which is in development for hemophilia, and the RaniPill HC oral delivery device (the “Device”) for use in humans. Under the Chugai Collaboration and License Agreement, the Company received a $10.0 million upfront payment and is eligible to receive up to $18.0 million in technology transfer milestones (of which $10.0 million is subject to the customer's option), up to $57.0 million in regulatory and development milestones, up to $100.0 million in a series of sales-based milestones, contingent upon approval and the commercial success of the Chugai Product, and single digit royalties on net sales upon approval and successful commercialization of the Chugai Product. Under the Chugai Collaboration and License Agreement, the Company granted Chugai an exclusive, worldwide right and license to certain intellectual property owned by the Company to research, develop, register, manufacture, use, sell, offer to sell, import, export, commercialize, and market the Chugai Product. Chugai granted the Company a non-exclusive, worldwide right and license to certain intellectual property owned by Chugai to manufacture and supply the Device and Chugai Product to Chugai and to perform activities under the Chugai Collaboration and License Agreement. Both parties have the right to sublicense subject to certain conditions. In addition, Chugai has a one-time limited option to replace the Compound with a different compound subject to certain terms and conditions, a time-limited right of first refusal with respect to a select group of additional targets, and a time-limited option to extend its rights to up to five of the additional drug targets, each exercisable upon payment of a $5.0 million additional target fee, under similar deal terms as the Chugai Collaboration and License Agreement. The parties have the right to terminate the Chugai Collaboration and License Agreement at any time through mutual written consent. Chugai has the unilateral right to terminate the Chugai Collaboration and License Agreement at will, without cause, by providing the Company with 60 days’ prior written notice. Upon termination, Chugai must wind down development, regulatory, and commercial activities and continue paying royalties on any remaining net sales made during the wind-down period. Further, both the Company and Chugai retain their ownership of intellectual property, program inventions, and the license automatically becomes exclusive, irrevocable, perpetual, and fully paid‑up in favor of Chugai, unless Chugai terminated the Agreement without cause. The Company determined that the Chugai Collaboration and License Agreement falls within the scope of Accounting Standards Codification ("ASC") Topic 808: Collaborative Arrangements ("ASC 808"), with certain elements accounted for under ASC Topic 606, Revenue from Contracts with Customer ("ASC 606"). Specifically, the exclusive license granted to Chugai, technology transfer of a sterile manufacturing process, sales-based milestones, and royalties are accounted for under ASC 606, while the development related activities are accounted for as collaborative arrangements under ASC 808. Under ASC 606, the Company concluded there is one combined performance obligation, primarily consisting of the exclusive license, the information transfer of the Company's intellectual property, and the sterile manufacturing process research and know-how transfer. The combined performance obligation conveys a right to use the Company's functional intellectual property, which has significant standalone value as Chugai has exclusive rights to use the Compound within the RaniPill. The performance obligation is a stand ready obligation that is satisfied over time by providing Chugai with ongoing access to the Company's leadership throughout the period of delivery of regulatory feedback on the sterile manufacturing process, in order to answer regulatory questions when and if they are asked. The Company uses the time based (straight line) measure of progress to recognize revenue for the arrangement over time as the performance obligation is satisfied, which is the period from license issuance through the period over which sterile manufacturing process research activities and the corresponding know-how transfer occur. Accordingly, the Company expects to recognize the initial $10.0 million transaction price between the execution of the arrangement through the expected completion date of the sterile manufacturing process transfer. As of December 31, 2025, the transaction price primarily consisted of the $10.0 million upfront payment. Additional variable considerations including development milestones have been excluded from the initial transaction price because achievement is not considered probable and is fully constrained due to uncertainties outside the Company's control. Based on its assessment as of June 30, 2026, the Company concluded that there were no changes in facts or circumstances that would result in any milestone‑related variable consideration becoming probable of achievement. As such, no variable consideration was included in the transaction price as of June 30, 2026. The Company will reassess milestone-related variable consideration each reporting period and will update the transaction price once it becomes probable and the associated constraint is lifted. Any milestone consideration included in the transaction price will be recognized when the milestone is achieved or consistent with the pattern of recognition of the associated performance obligation, including through cumulative catch-up adjustments, as applicable. For the three and six months ended June 30, 2026, the Company recognized $1.7 million and $3.4 million of revenue, respectively, on the condensed consolidated statement of operations. As of June 30, 2026, $5.1 million in revenue was deferred under this agreement as current deferred revenue on the condensed consolidated balance sheet. As of June 30, 2026, of the $10.0 million upfront payment, $8.0 million was received in cash and $2.0 million remains in accounts receivable relating to tax withheld by the Japanese tax authorities, which is expected to be refunded to the Company upon submission and acceptance of the required residency certificate. The Company submitted the required residency certificate in July 2026. The Company expects to collect the full amount and does not view the withholding as impacting the collectability assessment under ASC 606. Evaluation Arrangement In August 2024, the Company entered into a contract with Chugai to conduct evaluation services of certain Chugai compounds for oral delivery using the RaniPill HC (the "Chugai Research Agreement"), which was concluded to be a single performance obligation with an enforceable right to payment. The Company received an up-front payment of $0.6 million upon execution of the contract. Upon completion of the evaluation services, in April 2025, the Company was paid a final $0.6 million for an aggregate total of $1.2 million due under the contract. In addition, if agreed upon, the agreement allows for joint filing of certain intellectual property protection in which all associated expenses will be shared equally. Chugai has the ability to terminate the agreement at any time by providing 10 days’ written notice after the effective date of the contract. The contract can be terminated for cause by either party based on uncured material breach by the other party. Upon early termination, all ongoing activities under the agreement and all mutual collaboration, development and commercialization licenses and sublicenses will terminate. For the three and six months ended June 30, 2025, $0 and $0.2 million in contract revenue was recognized for evaluation services performed, respectively. As of June 30, 2026, no contract asset or contract liability was outstanding under the Chugai Research Agreement, as all consideration received had been recognized as revenue in proportion to the services performed. ProGen Co., Ltd. In June 2024, the Company and ProGen Co., Ltd. (“ProGen”) entered into a Collaboration Agreement (the “Collaboration Agreement”). Under the Collaboration Agreement, the Company and ProGen will collaborate to manufacture, develop, seek regulatory approvals for and, if approved, commercialize a product (the “Product” or “RT-114”) combining ProGen’s GLP-1/GLP-2 dual agonist compound, PG-102, and the RaniPill HC oral delivery device in the field of weight management (including without limitation obesity, weight reduction and weight maintenance) in humans (the “Collaboration”). Under the Collaboration Agreement, development costs, as well as operating profits and losses from the commercialization of the Product, will be equally shared by the Company and ProGen. The Company and ProGen each granted to the other party an exclusive right and license (except with respect to the other party’s affiliates and sublicensees) to certain intellectual property to develop the Product for weight management and an exclusive right and license to seek regulatory approval for, and to use, sell, offer to sell, import and commercialize the Product in their assigned territories. The parties share responsibility for the development of RT-114 worldwide, with the Company leading such development for preclinical activities through Phase 1 clinical trials. After initiation of the first Phase 2 clinical trial, the Company will lead development and commercialization of the Product in the United States, Canada, Europe (including the United Kingdom) and Australia, and ProGen will lead development and commercialization in all other countries. Each party has the right to opt-out of the Collaboration (“Opt-Out”) at any time upon prior written notice to the other party. Following an Opt-Out, the continuing party shall have sole right to develop, conduct regulatory activities for and commercialize the Product on a worldwide basis. The Opt-Out party shall share all development costs and operating profit (or loss) through the effective date of the Opt-Out, and all costs to complete the conduct of any clinical trials of Product that have been initiated prior to delivery of the Opt-Out notice, even if the costs are incurred or the trials are completed after the effective date of the Opt-Out. The continuing party shall pay to the Opt-Out party low single to mid-single digit royalties on net sales of the Product made after the Opt-Out date depending on when the Opt-Out occurs. The Company determined that the Collaboration Agreement is not a contract with a customer and is therefore accounted for under ASC 808. The Company evaluates the presentation of amounts due from ProGen based on the nature of each separate activity. Reimbursements from ProGen are recognized as contra-research and development expense on the Consolidated Statement of Operations once earned and collectability is assured. For the three and six months ended June 30, 2026, reimbursement due from ProGen recorded as contra-research and development expense was $0.1 million and $0.4 million, respectively. For the three and six months ended June 30, 2025, reimbursement due from ProGen recorded as contra-research and development expense was de minimis.

Chugai Collaboration and License Agreement

In October 2025, the Company entered into a Collaboration and License Agreement (the “Chugai Collaboration and License Agreement”) with Chugai Pharmaceutical Co., Ltd. (“Chugai”).
