Revenue Interest Purchase Agreement
Revenue Interest Liability
On December 29, 2023, we entered into the RIPA with Infinity and Oberland. Pursuant to the RIPA, Oberland acquired certain initial Revenue Interests from us for a gross purchase price of $200.0 million paid on closing, less $7.5 million of issuance costs. Oberland had the option to purchase additional Revenue Interests from us in exchange for a $100.0 million Second Payment upon satisfaction of certain conditions in the RIPA, including receipt of approval from the FDA of our BLA for ANKTIVA on or before June 30, 2024.
In April 2024, the FDA approved our product ANKTIVA and as a result, on May 13, 2024 Oberland purchased additional Revenue Interests from us for a gross purchase price of $100.0 million, less $3.1 million of issuance costs. The issuance costs incurred are being amortized to interest expense over the estimated term of the debt.
As consideration for the aforementioned payments, Oberland has the right to receive quarterly Revenue Interest Payments from us based on, among other things, a certain percentage of our net sales during such quarter, which are tiered payments ranging from 4.5% to 10.0% (before funding of the Second Payment, 3.0% to 7.0%) of the company’s worldwide net sales, excluding those in China.
If the aggregate Revenue Interest Payments made to Oberland as of December 31, 2029 (Test Date) equal or exceed the Cumulative Purchaser Payments ($300.0 million) as of that date, the initially tiered revenue interest rate will be decreased to a single rate of 2.25% (before the funding of the Second Payment, 1.50%) of the company’s worldwide net sales, excluding those in China. If the aggregate Revenue Interest Payments made to Oberland as of the Test Date are less than the aggregate amount of Cumulative Purchaser Payments as of the Test Date, then following the Test Date the initially tiered revenue interest rate will increase to a rate that, had such increased rate applied during the period from December 29, 2023 through December 31, 2029, it would have resulted in Oberland receiving aggregate Revenue Interest Payments (excluding certain payments detailed in the RIPA) equal to the Cumulative Purchaser Payments as of the Test Date. In addition, if aggregate Revenue Interest Payments made to Oberland as of the Test Date are less than the aggregate amount of Cumulative Purchaser Payments as of the Test Date, then the company must make the True-Up Payment.
Oberland’s rights to receive Revenue Interest Payments under the RIPA shall terminate when Oberland has received payments (including any True-Up Payment) equal to 195.0% of the then Cumulative Purchaser Payments unless the RIPA is terminated prior to such date (subject to certain Call/Put Option scenarios as described below). If Oberland has not received total payments (including any True-Up Payment) equal to 195.0% of the then Cumulative Purchaser Payments on or before the twelfth anniversary of the RIPA, then the company shall be obligated to pay to Oberland an amount equal to 195.0% of the then Cumulative Purchaser Payments less the aggregate payments (including any True-Up Payments) made as of such date.
The company’s obligations under the RIPA are guaranteed by certain of its subsidiaries meeting materiality thresholds set forth in the RIPA. To secure the company’s obligations under the RIPA and the subsidiary guarantors’ obligations under the guarantees, each of the company and the subsidiary guarantors has granted a security interest in substantially all its assets, subject to certain exceptions and limitations.
The RIPA contains affirmative and negative covenants and events of default, including covenants and restrictions that, among other things, restrict our ability to incur additional liens, incur additional indebtedness, make loans and investments, enter into transactions with affiliates, engage in mergers and acquisitions, engage in asset sales and exclusive licensing arrangements, and declare dividends to our stockholders, in each case, subject to certain exceptions set forth in the RIPA. As of December 31, 2025, the company was in compliance with all covenants.
The RIPA is considered a sale of future revenues and is accounted for as long-term debt recorded at amortized cost using the effective interest rate method. The company imputes interest expense associated with this liability using the effective interest rate method. The effective interest rate is calculated based on the rate that would enable the debt to be repaid in full over the anticipated life of the arrangement. The interest rate on this liability may vary during the term of the agreement depending on a number of factors, including the level of forecasted net sales. The company evaluates the interest rate quarterly based on its current net sales forecasts utilizing the prospective method.
On December 10, 2024, the company entered into an amendment to the RIPA to add additional conditions to the payment of certain existing indebtedness. Such amendment did not have an impact on the valuation or financial statement classification of the revenue interest liability or the embedded derivative liabilities related to the RIPA.
During the years ended December 31, 2025, 2024 and 2023, we recorded $51.5 million, $39.7 million and $0.3 million of interest expense, respectively, related to this arrangement.
The following table summarizes the revenue interest liability activity during the years ended December 31, 2025 and 2024 (in thousands):
Revenue interest liability, at December 31, 2023$155,415

Accrued revenue interest payment(839)

Embedded Derivative Liabilities
Under the RIPA, the company has a Call Option to terminate the RIPA and repurchase the Revenue Interests at any time upon advance written notice, subject to certain limitations set forth in the RIPA. Additionally, Oberland has a Put Option enabling them to terminate the RIPA and to require the company to repurchase the Revenue Interests upon enumerated events, such as a bankruptcy event, failure to make a payment, an uncured material breach, default in certain third-party agreements, a breach or default under any subordination agreements with respect to indebtedness to existing stockholders, or subordinated notes during certain time periods, judgments in excess of certain amounts against the company, a material adverse effect, the loss of regulatory approval of our product candidates or a change of control.
The required purchase price with respect to the Call Option and/or Put Option, as applicable, shall be (a) 120.0% of the Cumulative Purchaser Payments as of such date, if Oberland exercises the Put Option (other than in connection with a change of control) on or prior to the first anniversary the Closing Date, (b) 135.0% of the Cumulative Purchaser Payments as of such date, if the Put Option or the Call Option is exercised in connection with a change of control on or prior to the date that is eighteen (18) months after the Closing Date, and (c) in all other cases, (i) 175.0% of the Cumulative Purchaser Payments as of such date, if the Put Option or the Call Option is exercised no later than the date that is thirty six (36) months after the Closing Date, and (ii) 195.0% of the Cumulative Purchaser Payments as of such date, if the Put Option or the Call Option is exercised later than the date that is thirty six (36) months after the Closing Date, minus, in each case, the total payments made to Oberland on or prior to such date.
The aforementioned Call and Put Options are considered embedded derivatives requiring bifurcation as a single compound derivative instrument. The company estimated the fair value of the derivative liability using a “with-and-without” method. The “with-and-without” methodology involves valuing the whole instrument on an as-is basis and then valuing the instrument without the individual embedded derivative. The difference between the entire instrument with the embedded derivative compared to the instrument without the embedded derivative is the fair value of the derivative liability.
The company recorded $34.5 million for the initial fair value of the derivative liability upon the closing of the initial $200.0 million Revenue Interests acquired by Oberland. The company recorded an incremental $6.2 million for the fair value of the derivative liability upon the closing of the additional $100.0 million Revenue Interests acquired by Oberland in May 2024. The initial and incremental fair value allocated to the derivative liability is recorded against the RIPA as a debt discount, which is being amortized in interest expense, on the consolidated statement of operations over the expected term of the debt using the effective interest method. Such embedded derivative is classified in derivative liabilities, on the consolidated balance sheet. The embedded derivative is subsequently remeasured at fair value each reporting period using a Monte Carlo Simulation valuation technique, with the change in fair value being recorded in change in fair value of derivative liabilities, on the consolidated statement of operations.
The estimated probability and timing of underlying events triggering the exercisability of the Put Option contained in the RIPA, forecasted cash flows and the discount rate are significant unobservable inputs used to determine the estimated fair value of the entire instrument with the embedded derivative. As of December 31, 2025 and 2024, the discount rate used for valuation of the derivative liability was 11.7% and 10.4%, respectively.
The change in fair value of the derivative liability is as follows (in thousands):
Fair value, at December 31, 2023$34,500 
Change in fair value(14,850)
Embedded contingent derivative liability related to Second Payment6,150

Change in fair value(6,400)
Fair value, at December 31, 2025$19,400 
Stock Purchase and Option Agreement
In connection with the RIPA, we entered into a SPOA with Oberland pursuant to which we sold an aggregate of approximately $10.0 million of our common stock at $4.1103 per share in a private placement. Oberland also had an option to purchase up to an additional $10.0 million of our common stock, at a price per share to be determined by reference to the 30-day trailing volume weighted-average price of our common stock calculated from the date of exercise.
This stock purchase option was classified as a liability estimated at fair value at issuance. The initial $200.0 million received pursuant to the RIPA and $10.0 million received pursuant to the SPOA were allocated among the resulting financial instruments on a relative fair value basis, with $197.1 million allocated to the debt under the RIPA, $12.0 million allocated to the common stock issued under the SPOA, and $0.8 million allocated to the stock purchase option as of December 31, 2023.
In April 2024, Oberland exercised part of their option and purchased 858,990 shares of our common stock at an exercise price of $5.8208 per share generating net proceeds of approximately $4.9 million. In relation to this transaction, we recorded $7.6 million in additional paid-in capital, on the statement of stockholders’ deficit during the year ended December 31, 2024. Following such exercise, approximately $5.0 million remains available for future exercise under the SPOA as of December 31, 2025. This option expires on December 29, 2028.
This stock purchase option is classified in derivative liabilities, on the consolidated balance sheet at its fair value and is subsequently remeasured at fair value each reporting period, with the change in fair value being recorded in change in fair value of derivative liabilities, on the consolidated statement of operations.
The estimated fair value of the stock option purchase liability was computed using a Monte Carlo Simulation valuation technique that used the calculated exercise price and discounted it back to a present value at the risk-free rate with the following unobservable input at the following dates:

About Debt Disclosures

Debt disclosures detail a company's borrowing structure — the types of instruments, interest rates, maturity schedule, and covenant restrictions that define its financial obligations and flexibility. This section is essential for assessing refinancing risk, interest rate exposure, and the margin of safety against financial distress.

Key signals: the maturity schedule reveals concentration risk — large maturities within 1-2 years during tight credit markets can force dilutive refinancing or asset sales. Compare the fair value of debt against carrying amount to gauge whether the market views the company's credit risk differently than the balance sheet suggests. Watch covenant compliance disclosures for tightening cushions, especially leverage and interest coverage ratios. Variable-rate debt exposure quantifies sensitivity to interest rate changes. Secured versus unsecured mix affects recovery rates and future borrowing capacity. Compare net debt-to-EBITDA against industry peers and covenant limits to assess financial health.
