Organization, Consolidation and Presentation of Financial Statements [Abstract]

ORGANIZATION AND BASIS OF PRESENTATION

ORGANIZATION AND BASIS OF PRESENTATION

Organization. NovoCure Limited (including its consolidated subsidiaries, the "Company") was incorporated in the Bailiwick of Jersey and is principally engaged in the development, manufacture and commercialization of Tumor Treating Fields ("TTFields") devices, including Optune Gio and Optune Lua (collectively, our "Products"), for the treatment of solid tumor cancers. The Company markets Optune Gio and Optune Lua in multiple countries around the globe with the majority of revenues coming from the use of Optune Gio in the U.S., Germany, France and Japan. The Company also has a License and Collaboration Agreement (the "Zai Agreement") with Zai Lab (Shanghai) Co., Ltd. ("Zai") to market Optune in China, Hong Kong, Macau and Taiwan ("Greater China").

Financial statement preparation. The accompanying unaudited consolidated financial statements include the accounts of the Company and intercompany accounts and transactions have been eliminated. In the opinion of the Company’s management, the unaudited consolidated financial statements reflect all adjustments, which are normal and recurring in nature, necessary for fair financial statement presentation for the periods presented. The preparation of these unaudited consolidated financial statements in conformity with U.S. generally accepted accounting principles ("GAAP") requires management to make estimates and assumptions that affect the amounts reported in these unaudited consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates. These unaudited consolidated financial statements and accompanying notes should be read in conjunction with the Company’s annual consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025 (the "2025 10-K") filed with the Securities and Exchange Commission on February 26, 2026.

The significant accounting policies applied in the audited annual consolidated financial statements of the Company as disclosed in the 2025 10-K are applied consistently in these unaudited interim consolidated financial statements except for the adoption of ASU 2025-05, Financial Instruments - Credit Losses (Topic 326): "Measurement of Credit Losses for Accounts Receivable and Contract Assets”, see below.

Concentration Risks. The Company's cash, cash equivalents, short-term investments and trade receivables are potentially subject to a concentration of risk. Cash, cash equivalents and short-term investments are invested at top tier financial institutions globally and the total value invested at any one institution is limited pursuant to the Company's investment policy. These investments may be in excess of insured limitations or not insured in certain jurisdictions. Generally, these investments may be redeemed upon demand according to the terms of the securities.

The Company's trade receivables are due from numerous governments and federal and state agencies that are paid from their respective budgets, and from hundreds of health insurance companies. The Company does not believe that there are significant default risks associated with these governments, agencies and health insurance companies based upon the Company's historical experience.

The Company has no off-balance sheet concentrations of credit risk such as foreign exchange contracts, option contracts or other foreign hedging arrangements.

Recently adopted accounting pronouncements

In November 2024, the FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, requiring public entities to disclose additional information about specific expense categories in the notes to the financial statements on an interim and annual basis. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and for interim periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact of adopting ASU 2024-03.

In July 2025, the FASB issued ASU 2025-05, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets. This amendment introduces a practical expedient for the application of the current expected credit loss (“CECL”) model to current accounts receivable and contract assets. ASU 2025-05 is effective for fiscal years beginning after December 15, 2025, and interim reporting periods within those annual reporting periods. Early adoption is permitted. The Company adopted ASU 2025-05 on January 1, 2026, on a prospective basis, and elected the practical expedient provided by ASU 2025-05. Under this expedient, the Company assumes that economic conditions as of the balance sheet date remain unchanged for the

remaining life of all current accounts receivable and current contract assets arising from transactions under ASC 606. The Company continues to estimate expected credit losses for non-current receivables and contract assets in accordance with ASC 326. The adoption of ASU 2025-05 did not have any material impact on the consolidated financial statements.

In September 2025, the FASB issued ASU 2025-06, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40) - Targeted Improvements to the Accounting for Internal-Use Software. The ASU was updated to consider different methods of software development and requires internal use software costs to be capitalized when management has authorized and committed to funding the software project and when significant uncertainty associated with the development of the software has been resolved. The amendments in this ASU are required to be adopted for annual and interim reporting periods beginning after December 15, 2027 (the year ending December 31, 2028, for the Company), with early adoption permitted, and may be applied either through a prospective, retrospective or a modified transition approach. The Company is currently evaluating the effect of adopting the ASU on its consolidated financial statements.

In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements, which clarifies interim disclosure requirements and the applicability of Topic 270. This update will be effective beginning after December 15, 2027. The Company is currently evaluating the impact that adoption of ASU 2025-11 will have on its consolidated financial statements.
