Investment in Joint Ventures The Company has elected to measure the investment in joint ventures using the fair value option at each reporting date. Under the fair value option, bifurcation of an embedded derivative is not necessary, and all related gains and losses on the host contract and derivative due to change in the fair value will be reflected in other income (expenses), net in the unaudited condensed consolidated statements of operations and comprehensive loss. The value at which the Company’s investment in joint ventures is carried on its books is adjusted to estimated fair value at the end of each quarter, taking into account general economic and stock market conditions and those characteristics specific to the underlying investments. Investment in Zylö Therapeutics In connection with the Company’s March 2020 underwritten public offering of shares of its common stock, on May 4, 2020, the Company purchased 120,000 shares of Zylö Therapeutics (“Zylö”) Class B common stock for $60,000. On December 8, 2021, the Company entered into a third amendment (the “Zylö Amendment”) to the Exclusive Sublicense Agreement with Zylö originally dated August 19, 2019 (as amended, the “Exclusive Sublicense Agreement”), pursuant to which the Company licensed its novel cannabinoid therapeutic, HT-005 for lupus patients, back to Zylö. Pursuant to the Zylö Amendment, on December 6, 2021, Zylö issued the Company 100,000 shares of its Class B common stock. In addition, pursuant to the Zylö Amendment, within 90 days following a sale by Zylö of all of its assets and rights related to HT-005 to a third-party (a “Sale”), Zylö shall pay the Company a low single digit percent of the net proceeds received by it attributable to HT-005 in the United States and Canada and their respective territories (collectively, the “Territory”) for the purposes of therapeutic uses related to lupus in humans (the “Field”). After the Sale, any and all rights of the Company pursuant to the Exclusive Sublicense Agreement, including all amendments thereto, shall terminate. Furthermore, pursuant to the Zylö Amendment, following the date of the first commercial sale of HT-005 in the Territory, in the Field, Zylö shall pay the Company (i) a low single digit percent of the Net Sales (as defined in the Exclusive Sublicense Agreement) of HT-005 in the event HT-005 is sold in the Territory and (ii) a low double digit percent of any royalty that Zylö receives through the sublicense to a third-party based on Net Sales of HT-005 in the Territory which payments shall continue in each country in the Territory until expiration of the last-to-expire Valid Claim (as defined in the Exclusive Sublicense Agreement). Zylö conducted a 409A valuation of their Class B common stock in February 2024, and as of June 30, 2025 and December 31, 2024, valued its share price at $0.167 and $0.167 per share, respectively. This value was ratified by Zylö’s board of directors in February 2024 and December 2023, respectively. On February 23, 2024, the Company acquired 22,000 shares of Class B Common stock of Atticus Pharma, a subsidiary of Zylö Therapeutics, based upon a 1-for-10 ratio of current shares and was instructed, on July 3, 2024, that the 409A valuation of the shares was $79, or $0.0036 per share, pursuant to the February 2024 valuation ratified by Zylö’s board of directors. The valuations reflect a probability-weighted present value of expected future investment returns considering certain possible outcomes and the rights of each class of Zylö’s and Atticus Pharma’s equity. The future values of the common stock under the various outcomes are discounted back to the valuation date at a risk-adjusted discount rate and probability weighted to determine the value for the Class B common stock. Significant unobservable inputs in the valuation include (i) probabilities of each scenario, (ii) timing of occurrence, (iii) future valuation; (iv) and the risk-adjusted discount rate. The consolidated investment in Zylö was valued at $36,819 and $36,819 as of June 30, 2025 and December 31, 2024, respectively.
