(2) The Company's fair value investments in common stock were comprised of marketable equity securities in two publicly traded companies that were purchased in October 2024 and March 2025, all of which were sold in July 2025. (3) The Company's measurement alternative method investment was comprised of Triple Ring as of both September 30, 2025 and December 31, 2024. The Company's recognized share of net losses from its equity method investments was zero for both the three months ended September 30, 2025 and 2024, respectively, and totaled $5.9 million and $2.3 million for the nine months ended September 30, 2025 and 2024, respectively. MediBeacon Pansend accounts for its preferred stock investment in MediBeacon under the equity method of accounting, inclusive of any fixed maturity securities (notes) issued by MediBeacon to Pansend. On January 17, 2025, MediBeacon received approval from the U.S. Food and Drug Administration ("FDA") for its Transdermal GFR Measurement System ("TGFR"). Pursuant to the terms of MediBeacon's convertible notes, upon the FDA approval, Pansend's convertible notes of $11.4 million and the related accrued interest of $1.5 million, together totaling $12.9 million, were converted into Series 3 Preferred Stock. In addition, pursuant to its amended commercial partnership with Huadong and, as a result of FDA approval, a $7.5 million milestone payment from Huadong Medicine Co. Ltd ("Huadong"), a publicly traded company on the Shenzhen Stock Exchange, to MediBeacon for MediBeacon preferred stock was received in the first quarter of 2025. As a result of these transactions, Pansend's ownership in MediBeacon decreased from 45.9% prior to the transactions to 44.7% subsequent to the transactions. On a fully diluted basis, Pansend's ownership in MediBeacon decreased from 40.1% to 39.7%. As a result of these transactions, Pansend recognized a step-up gain of $4.4 million which is reflected in Other (expense) income, net in the Condensed Consolidated Statements of Operations for the nine months ended September 30, 2025, which increased Pansend's carrying amount of its investment in MediBeacon. Concurrently, Pansend recognized equity method losses of $5.9 million, driven by the $4.4 million step-up gain and $1.5 million of interest from the conversion of the convertible notes, which were previously unrecognized because Pansend's carrying amount of its investment in MediBeacon had been previously reduced to zero. MediBeacon's total outstanding principal amount of notes due to Pansend was $0.5 million and $12.0 million, as of September 30, 2025 and December 31, 2024, respectively. Interest income earned by Pansend from the MediBeacon notes totaled $15 thousand and $0.3 million for the three months ended September 30, 2025 and 2024, respectively, and totaled $0.1 million and $1.0 million for the nine months ended September 30, 2025 and 2024, respectively. The related accrued interest receivable was $0.4 million and $1.7 million, as of September 30, 2025 and December 31, 2024, respectively. As of September 30, 2025, Pansend's carrying amount of its investment in MediBeacon remained at zero, inclusive of the $0.5 million in secured promissory notes which has been offset against recognized equity method losses, and Pansend has cumulative unrecognized equity method losses relating to MediBeacon of $18.2 million. Marketable Securities In October 2024, the Company purchased common shares in the open market of a publicly traded company for approximately $2.0 million, and in March 2025, the Company purchased common shares in the open market of another publicly traded company for $0.3 million. Both purchases represented less than 1% of the total outstanding equity of the respective issuers. In July 2025, all of these shares were sold for aggregate proceeds of $2.9 million. Prior to their disposal, these securities were remeasured at fair value each reporting period using the externally quoted market prices, Fair Value Level 1 inputs. For the three and nine months ended September 30, 2025, fair value gains of $0.3 million and $0.8 million, respectively, related to these securities were included in Other income, net in the Condensed Consolidated Financial Statements.
