Basis of presentation
The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP") for interim financial reporting and pursuant to the requirements for reporting on Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information required for the full annual financial statements and should be read in conjunction with the annual consolidated financial statements of the Company for the year ended December 31, 2025, included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (the "SEC") on February 25, 2026 (the "Annual Report").
The accompanying condensed consolidated financial statements contain all normal recurring adjustments necessary to present a fair statement of the financial position, results of operations, and cash flows for the interim periods reported. In the opinion of management, all adjustments considered necessary to present fairly the results of the interim periods have been included and consist only of normal and recurring adjustments. Certain information and footnote disclosures have been condensed or omitted as permitted under U.S. GAAP. The results for the three months ended March 31, 2026 are not necessarily indicative of the results to be expected for the year ending December 31, 2026, any other interim periods, or any future year or period.
Use of estimates
The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make judgments, estimates and assumptions. These judgments, estimates and assumptions affect the reported assets and liabilities as well as income and expenses in the financial period.
The estimates and associated assumptions are based on information available when the condensed consolidated financial statements are prepared, historical experience and various other factors which are believed to be reasonable under the circumstances, the results of which form the basis of making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources.
Existing circumstances and assumptions about future developments, however, may change due to market changes or circumstances arising that are beyond the Company’s control. Actual results could differ from those estimates. Estimates are primarily made in relation to revenue recognition, operating lease incremental borrowing rates, share-based compensation expense, clinical accruals, and deferred tax asset valuation allowances.
Fair value measurements
Where financial and non-financial assets and liabilities are measured at fair value, the Company uses appropriate valuation techniques for which sufficient data are available, maximizing the use of relevant observable inputs and minimizing the use of unobservable inputs.
As of March 31, 2026 and December 31, 2025, the Company held $353.0 million and $366.8 million, respectively, of money market funds required to be measured at fair value on a recurring basis within cash and cash equivalents. In addition, as of March 31, 2026 and December 31, 2025, the Company held $392.2 million and $396.4 million of marketable securities, respectively. The Company recorded unrealized gains of $1.8 million for the three months ended March 31, 2026 and $5.5 million for the three months ended March 31, 2025, respectively on these marketable securities. The fair value of these cash equivalents and marketable securities is based on quoted prices from active markets (Level 1 inputs). Other financial instruments, although not recorded at fair value on a recurring basis, include cash, accounts receivable, accounts payable and debt obligations.
The fair value of borrowings under the convertible senior notes (the “Notes”, disclosed in Note 5. “Interest-bearing loans and borrowings”) were based on Level 2 inputs, which include observable inputs estimated using discounted cash flows and market-based expectations for interest rates, credit risk, and the contractual terms of debt instruments. After initial recognition, borrowings are measured at amortized cost using the effective interest method.

Significant accounting policies
The significant accounting policies used in the preparation of these condensed consolidated financial statements as of and for the three months ended March 31, 2026 are consistent with those disclosed in Note 2. "Summary of Significant Accounting Policies" in the audited consolidated financial statements for the year ended December 31, 2025, included in the Company’s Annual Report.

Recently issued and recently adopted accounting pronouncements
In November 2024, the FASB issued ASU 2024-03, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40). This ASU requires disclosure in the notes to the financial statements, at each interim and annual reporting period, of specified information about certain costs and expenses including purchases of inventory, employee compensation, depreciation and intangible asset amortization included in each relevant expense caption. Also required is a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated. This ASU is effective for all public entities for annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027, and early adoption is permitted. This ASU should be applied either prospectively to financial statements issued after the effective date of this update or retrospectively to any or all prior periods presented in the financial statements. The Company is currently evaluating these new disclosure requirements and the impact of adoption on its financial statements.
