Note 4 - Fair Value

Recurring Fair Value Measurements

Our borrowing instruments are recorded at their carrying values in the balance sheets, which may differ from their respective fair values. The fair value of borrowings as of December 31, 2025 and 2024 is primarily associated with the Perceptive Term Loan Facility entered into with Perceptive Credit Holdings IV, LP in November 2022 and was determined using a discounted cash flow analysis, excluding the fair value of the Perceptive Warrant (as defined below) issued in conjunction with the transaction. The carrying value of outstanding borrowings approximates the fair value as of December 31, 2025. The difference between the carrying value and fair value of outstanding borrowings as of December 31, 2024 is due to an increase in the fair value of debt as a result of improved credit markets. The table below presents the carrying and fair values of outstanding borrowings, which are classified as Level 2, as of the dates indicated (in thousands):

The financial liabilities that are measured and recorded at estimated fair value on a recurring basis consist of the warrant liabilities granted as consideration for the Perceptive Term Loan Facility (see Note 8 – Debt), contingent value rights granted to certain holders of our previously converted Series F Preferred Stock, and, prior to 2025, contingent consideration associated with our previous acquisition of Indi, which were accounted for as liabilities and remeasured through our statements of operations. The fair values of these financial liabilities are classified as Level 3 in the fair value hierarchy, however, as of December 31, 2025 and 2024, there are no liability balances associated with warrant liabilities, contingent value rights, or contingent consideration.

Warrant Liabilities

On November 21, 2022, as consideration for the Perceptive Term Loan Facility (see Note 8 – Debt), the Company issued Perceptive a warrant to purchase up to 250,000 shares of the Company's common stock (the Perceptive Warrant), including Initial Warrants (as defined in Note 10 – Equity below) and Tranche B and C Warrants. The Initial Warrants are equity classified (see Note 10 – Equity) while the Tranche B and C Warrants were initially classified as liabilities and recognized at fair value. On December 15, 2023 (the Tranche B Borrowing Date), the Company exercised its ability to draw the Tranche B loan (see Note 8 – Debt). In connection with the Tranche B draw, the Company remeasured the Tranche B Warrants through the Tranche B Borrowing Date and recorded the change in

fair value through the statements of operations and, subsequently, reclassified the fair value to additional paid-in capital (see Note 10 – Equity).

The fair value of the Tranche C Warrants was determined using a Black-Scholes option-pricing model and subject to certain unobservable inputs. The significant unobservable inputs used in the measurement of the fair value included the fair value of the Company's common stock, risk-free rate, the volatility of common stock, and the probability of the expected borrowing. The Tranche C loan had a prior commitment date through September 30, 2024 and, as of that date, the Company did not exercise its ability to draw the Tranche C loan. On February 28, 2025 (the Fifth Amendment Effective Date), the Company entered into the Fifth Amendment to the Credit Agreement and Guaranty (the Fifth Amendment) with Perceptive (see Note 8 – Debt), whereby subject to the terms and conditions of the Fifth Amendment, the Tranche C Loan Commitment Termination Date (as defined in the Credit Agreement) was extended, providing continued availability to the Tranche C Loan through December 31, 2025. In addition, on the Tranche C Loan Borrowing Date (as defined in the Credit Agreement), the Tranche C Warrants, as amended, would become vested and exercisable at an exercise price equal to $15.86, the Company's closing stock price on February 28, 2025.

On May 8, 2025, the Company exercised its ability to draw the Tranche C loan under the Perceptive Term Loan Facility for $10.0 million (the Tranche C Loan) pursuant to the Credit Agreement. As consideration for drawing the Tranche C Loan, the Company agreed to modify the previously agreed upon per share exercise price of $15.86 for the Tranche C Warrants to a new per share exercise of $8.382, which was equal to the 10-day VWAP of the Company’s common stock on May 9, 2025, the business day immediately preceding the Tranche C Loan borrowing date. In connection with the Tranche C draw, the Company remeasured the Tranche C Warrants through the Tranche C Borrowing Date and recorded the change in fair value through the statement of operations and, subsequently, reclassified the fair value to additional paid-in capital (see Note 10 – Equity).

During the year ended December 31, 2025, the Company recorded a loss of $0.3 million as a change in fair value through the statements of operations due to changes in unobservable inputs. During the year ended December 31, 2024, the Company recorded no change in fair value through the statements of operations.

Contingent Value Rights

In January 2016, the Company issued shares of Series F Preferred Stock (the Series F Offering) that were subsequently converted into common stock in connection with the Company's initial public offering in October 2020. In connection with the Series F Offering, investors who purchased more than their pro-rata amount in the financing received a calculated number of contingent value rights (CVRs). One CVR represents 0.00375% of the Company’s interest in the drug ficlatuzumab, which began a Phase 3 clinical trial in January 2024 (see Note 16 - Commitments and Contingencies below). In January 2016, the Company issued 3,999 CVRs, or 15% interest in the drug ficlatuzumab, originally valued at $0.5 million. The initial estimated value of the CVRs were recorded as a liability and as a reduction to the Series F proceeds. Subsequent to recoupment of our initial co-development costs, upon receipt of a milestone, royalty, or any other type of payment from the Company’s ownership rights in the drug, the Company is required to make a cash payment to the CVR holders equal to 15% of net proceeds, as defined. During the years ended December 31, 2025 and 2024, the Company recorded no change in fair value due to the remote probability of receiving net proceeds in excess of our initial co-development costs.

Contingent consideration

In connection with the acquisition of Indi in 2018, the Company recorded contingent consideration for amounts contingently payable to Indi's selling shareholders pursuant to the terms of the asset purchase agreement (the Indi APA). The contingent consideration arrangement required additional consideration to be paid by the Company to such shareholders upon attainment of a three-consecutive month gross margin target of $2.0 million within the seven-year period after the acquisition date, which was achieved during the three months ended June 30, 2021. Under the terms of the original agreement, when the gross margin target was achieved, the Company was required to issue 2,520,108 shares of common stock. For the six months following the achievement of the gross margin target, Indi had the option to require the Company to redeem these common shares for $37.0 million in cash over eight equal quarterly installments. If Indi elected to not exercise its option, the Company had 12 months to repurchase the common stock in two equal and consecutive quarterly cash installments totaling $37.0 million.

In August 2021, the Company entered into an amendment to the original agreement in which all parties agreed to forgo the issuance of common stock and agreed that the Company would, in lieu thereof, make six quarterly installments of approximately $4.6 million each beginning in January 2022 and a final payment of approximately $9.3 million in July 2023 for a total of $37.0 million (the Milestone Payments and each individually a Milestone Payment). The aggregate amount of payments owed by the Company under this amendment was the same as if Indi had exercised the put right or the Company had exercised the call right provided for in the original agreement.

On April 7, 2022, the Company entered into Amendment No. 3 to the Indi APA, in which the parties agreed to restructure the Milestone Payments. The Company made five quarterly installments of $2.0 million each beginning in April 2022, three quarterly installments of $3.0 million which began in July 2023, one installment of $5.0 million in April 2024, and one installment of $8.4 million in July 2024. In addition, the Company agreed to an exit fee of approximately $6.1 million to be paid in October 2024. Interest accrued on the difference between the payment schedule as agreed in the August 2021 amendment and the April 2022 amended payment schedule, at an aggregate per annum rate equal to 10%, with such interest payable quarterly on the following installment payment date. Our ability

to make these payments was subject to ongoing compliance under the Perceptive Term Loan Facility. On September 30, 2024, the Company obtained consent from Perceptive and prepaid the October 1, 2024 exit fee of $6.1 million to Indi. The Company has no remaining obligations to Indi.

During the year ended December 31, 2024, the Company recorded $1.1 million in interest expense due to the passage of time and fixed payment schedule.
