On August 25, 2021, the Company entered into a royalty purchase agreement with certain entities managed by HCR for up to $325.0 million. Under the terms of the agreement, the Company received gross proceeds of $225.0 million upon closing (the “First Investment Amount”) and received an additional $75.0 million during the year ended

On February 18, 2026, the Company entered into an amendment (the “HCR Amendment”) to the Purchase and Sale Agreement, dated August 25, 2021 (the “Original HCR Agreement” and, as amended by the HCR Amendment, the “Amended HCR Agreement”). Under the Original Agreement, upon the occurrence of a change of control event, the Company is obligated to pay HCR $750 million (or $675 million if HCR receives royalty payments exceeding a mid-nine-digit amount on or prior to March 31, 2029), less the amount of royalties previously paid to HCR. Under the Amended HCR Agreement, upon the occurrence of a change of control event, the Company is obligated to pay HCR $150 million (if the change of control event occurs on or before December 31, 2027) or $200 million (if the change of control event occurs on or after January 1, 2028), which amount is not reduced by the amount of royalties previously paid to HCR. In addition, following such change of control event, the royalty obligations under the Amended HCR Agreement will continue until the Royalty Cap (as defined in the Original HCR Agreement), unless the Company (or its successor in interest) buys out the remaining royalty obligations by paying HCR $525 million (if the buyout occurs on or prior to December 31, 2029) or $750 million (if the buyout occurs on or after January 1, 2030), less the amount of royalties previously paid to HCR and the change of control payment described above.

In connection with the HCR Amendment, the Company issued to HCR warrants (the “HCR Warrants”) to purchase 9,834,776 common shares. The HCR Warrants are exercisable at any time after their original issuance until December 31, 2030. The exercise price per common share purchasable upon the exercise of the HCR Warrants is $3.81 per share, subject to customary adjustments. The HCR Warrants have certain limitations on exercise, including (i) any exercise must be for at least 50,000 common shares (or, if less, the remaining common shares available for purchase under the HCR Warrants) and (ii) cashless exercise is not available in certain circumstances as specified in the HCR Warrants. The HCR Warrants contain customary anti-dilution adjustments and will entitle holders to receive any dividends or other distributions paid on the underlying common shares prior to their expiration on an as-exercised basis. The HCR Warrants and any common shares issuable upon exercise of the warrants are not transferable on or prior to December 31, 2027, except, with respect to common shares issued upon exercise of the warrants, in connection with the consummation of certain fundamental transactions.

The Company assessed the HCR amendment for a debt extinguishment or modification in accordance with ASC-470-50. The fair value of the warrants issued was determined to be $20.8 million at the time of issuance. The HCR amendment was accounted for as a debt modification as the present value of future cashflows of the modified agreement compared to that of the original agreement resulted in a less than 10% change. As a result, the Company did not incur any gain or loss relating to the modification. The fair value of the warrants is presented as a direct reduction to the carrying value of the debt. The Company will continue to account for the value of the debt at amortized cost.

The HCR warrants are recognized as a warrant obligation and presented in the unaudited condensed consolidated balance sheet as a liability given the existence of a net settlement feature under which the holder may settle in cash equal to the par value, with the amount payable indexed to the CHF/USD exchange rate, and receive the underlying shares on a net basis. The warrant obligation was recorded at its initial fair value of $20.8 million at the time of issuance as described further above. Subsequent to issuance, the warrant obligation is remeasured to fair value at the end of each reporting period. Changes in the fair value (gains or losses) of the warrant obligation at the end of each period is recorded in the unaudited condensed consolidated statement of operations.

During the three and six months ended June 30, 2026, the Company recognized income of $14.4 million and $16.6 million, respectively, as a result of changes in the fair value of the warrant obligation. This amount was recorded to Other, net in the unaudited condensed consolidated statement of operations. The fair value of the warrant obligation as of June 30, 2026 was $4.2 million.
