Fair value measurement

The Company measures certain financial assets and liabilities at fair value, either upon initial recognition or for subsequent accounting or reporting. ASC 820, Fair Value Measurement requires disclosure of the methodologies used in determining the reported fair values and establishes a hierarchy of inputs used when available. The three levels of the fair value hierarchy are described below:

Level 1 – Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities that the Company can access at the measurement date.

Level 2 – Valuations based on quoted prices for similar assets or liabilities in markets that are not active or models for which the inputs are observable, either directly or indirectly.

Level 3 – Valuations that require inputs that reflect the Company’s own assumptions that are both significant to the fair value measurement and are unobservable.

To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized as Level 3. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

The carrying amount of cash and cash equivalents, accounts receivable from licensing and collaboration partners, other assets, accounts payable, accrued expenses and other current liabilities reflected in the Unaudited Consolidated Balance Sheets approximate their fair values due to their short-term maturities.

The Company’s material financial assets include cash and cash equivalents, restricted cash and investment securities. Cash and cash equivalents and restricted cash are measured at fair value using Level 1 inputs. Restricted cash is included in Other non-current assets within the Unaudited Consolidated Balance Sheets. Investment securities are measured at amortized cost.

The following table sets forth the Company’s assets and liabilities that are required to be measured at fair value on a recurring basis as of June 30, 2026 and December 31, 2025:

a)Contingent consideration

The Company is required to pay up to EUR 143.1 million (or $163.0 million based on the foreign exchange rate on June 30, 2026) to the former shareholders of uniQure France SAS (formerly Corlieve Therapeutics SAS) upon the achievement of the remaining contractually defined milestones related to the development of AMT-260 in connection with the Company’s acquisition of uniQure France SAS.

The fair value of the contingent consideration as of June 30, 2026 was EUR 15.9 million ($18.1 million) (December 31, 2025: EUR 15.9 million ($18.7 million)) using discount rates of approximately 10.1% to 11.8% (December 31, 2025: 11.8%).

If, as of June 30, 2026, the Company had assumed a 100% likelihood of AMT-260 advancing into a Phase III clinical study, then the fair value of the contingent consideration would have increased to EUR 51.3 million ($58.4 million). If, as of June 30, 2026, the Company had assumed that it would discontinue development of the AMT-260 program, then the contingent consideration would have been released to income.

The following table presents the changes in fair value of the contingent consideration (presented within non-current liabilities) between December 31, 2025 and June 30, 2026:

The Company classified the total contingent consideration liability as non-current as of June 30, 2026 and December 31, 2025. The classification of the contingent consideration within the Company’s Unaudited Consolidated Balance Sheets between current and non-current liabilities is based upon the Company’s best estimate of the timing of settlement of the remaining relevant milestones.

b)Liability related to pre-funded warrants

In September 2025, the Company completed a follow-on public offering which included the issuance of pre-funded warrants to purchase 526,316 of the Company’s ordinary shares at the public offering price of $47.50 per ordinary share, less a $0.0001 per ordinary share exercise price for each pre-funded warrant (“Pre-Funded Warrant(s)”). The obligation to issue ordinary shares upon the exercise of the Pre-Funded Warrants is classified as a liability related to pre-funded warrants.

The Pre-Funded Warrants are not exchange-quoted and are measured using a valuation technique whose significant inputs are observable; therefore, the fair value measurement is classified within Level 2 of the fair value hierarchy.
