OUT-LICENSE AGREEMENTS	OUT-LICENSE AGREEMENTS Out-License of TP-03 Commercial Rights in the China Territory in March 2021 In March 2021, the Company entered into the China Out-License with LianBio for its exclusive development and commercialization rights of TP-03 (lotilaner ophthalmic solution) 0.25% in the China Territory for the treatment of Demodex blepharitis and MGD. Prior to the March 2024 Novation Agreement to GrandPharma discussed in detail below, LianBio was contractually responsible for all clinical development and commercialization activities and costs within the China Territory. The Company assessed this arrangement and identified the following material promises under the arrangement: (i) the exclusive license to research, develop, manufacture, commercialize, make, offer for sale, sell, and import TP-03 in the China Territory; and (ii) the research and development services in the form of clinical study materials for the respective Phase 2b/3 trial (Saturn-1) and Phase 3 (Saturn-2) TP-03 trials. The promises to provide research and development services for Saturn-1 and Saturn-2 clinical trials were evaluated and determined to be distinct promises in the contract and each of the two clinical trials are separate performance obligations apart from the promise to provide the license. The assessment of the initial transaction price for the China Out-License included an analysis of amounts the Company expected to receive, which at contract inception consisted of: (i) the upfront cash payment of $15.0 million; (ii) a second cash payment of $10.0 million; (iii) a $10.0 million milestone that was determined to be within the control of the Company; and (iv) $1.2 million representing the initial fair value of equity warrants. The Company accounted for each performance obligation as follows: Out-License The Company determined that this license was distinct based on an evaluation of the delivery of the functional license that was in the later stages of development, and it met the criteria for being distinct from the research and development services required under the China Out-License. The Company determined the standalone selling price of this license using a discounted projected sales model and recognized as license fees and collaboration revenue the total allocated transaction price at contract inception, upon delivery of the license. Research and Development Services The standalone selling price of these performance obligations was determined using the adjusted market assessment approach. The Company analyzed costs expected to be incurred for each of the clinical trials through completion to estimate the price that a customer would be willing to pay for these services in order to benefit from the clinical trials. The Company determined that LianBio simultaneously benefited from the research and development services that are satisfied over time, as they were able to request and access the clinical trial data at any point through the trial completion. Therefore, the Company recognized the amounts allocated to the respective research and development performance obligations for the Saturn-1 and Saturn-2 clinical trials within license fees and collaboration revenue as the research and development services were provided using an input method, based on the costs incurred for each clinical trial and the total costs expected to be incurred to satisfy each performance obligation. The Company believes this method most faithfully depicted its performance in transferring the promised services during the expected period of time that each clinical trial was ongoing. The Company monitored the expected completion dates for each clinical trial and updated its estimated time to completion at each reporting period, as necessary. In February 2024, LianBio announced its plan to wind down its operations and in March 2024 made a special cash dividend payment to the Company of $0.7 million (equivalent to $4.80 per share - see Note 3). In March 2024, the Company executed an agreement with GrandPharma and LianBio to transition the rights to develop and commercialize TP-03 in China for Demodex blepharitis and MGD from LianBio to GrandPharma ("the Novation Agreement") and, upon execution of the Novation Agreement, the China Out-License with LianBio was assigned to GrandPharma with a one-time payment of $2.5 million (the "Termination Payment") made to the Company from LianBio in April 2024. This Termination Payment was recorded as license fees and collaboration revenue in the Condensed Statements of Operations and Comprehensive Loss for the six months ended June 30, 2024. The Novation Agreement amended the $15.0 million future development milestone payable on China regulatory approval of the China Out-License with a combined condition of patent issuance related to TP-03 in China. Simultaneous with the execution of the Novation Agreement, the Company entered into a warrant termination agreement (the "Warrant Termination Agreement") for a total cancellation payment of $0.4 million (the "Warrant Cancellation Payment"). This Warrant Cancellation Payment was recorded as license fees and collaboration revenue in the Condensed Statements of Operations and Comprehensive Loss for the six months ended June 30, 2024. Through June 30, 2025, the Company received aggregate payments from LianBio totaling $86.1 million, comprised of (i) initial consideration of $15.0 million, (ii) $67.5 million for the achievement of specified milestones, (iii) $2.5 million upon execution of the Novation Agreement, (iv) $0.4 million upon execution of the Warrant Termination Agreement, and (v) $0.7 million related to a special cash dividend. As of June 30, 2025 the Company is eligible to receive further consideration from GrandPharma upon the achievement of additional TP-03 events, including: (i) additional regulatory approval and/or patent issuance milestones of up to an aggregate of $20.0 million; (ii) China-based TP-03 sales threshold milestone payments of up to an aggregate of $100.0 million; and (iii) tiered low-to-high-teen royalties for China Territory TP-03 product sales. The variable consideration related to the remaining milestone payments was fully constrained as of June 30, 2025.
