Basis of presentation

These condensed consolidated interim financial statements have been prepared on the historical cost basis except for certain financial instruments and equity investments that are measured at fair value. Financial assets and equity investments classified as fair value through profit or loss are measured at their fair value at each reporting date, with changes in fair value recognized in profit or loss during the period in which they arise. Investments in joint ventures over which the Company has significant influence, but not control, are accounted for using the equity method in accordance with IAS 28 Investments in Associates and Joint Ventures. Such investments are initially recognized at cost and are subsequently adjusted to reflect the Company’s share of the investee's profits or losses and distributions received.

These condensed consolidated interim financial statements are presented in the United States dollar ("USD"), and all values are rounded to the nearest thousand except as otherwise indicated.

The functional currency of all subsidiaries is USD. For these entities, all transactions not denominated in USD functional currency are considered to be foreign currency transactions.

Critical accounting estimates and judgments

The preparation of financial statements requires management to make judgments, estimates and assumptions that affect the application of policies and reported amounts of assets, liabilities and contingent liabilities as of the date of the financial statements, and the reported amount of revenues and expenses during the reporting period. Estimates and judgments are continuously evaluated and are based on management’s experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. Actual results may differ from these estimates.

Information about critical judgments in applying accounting policies and assumptions and estimation uncertainties that have the most significant effect on the amounts recognized in the condensed consolidated interim financial statements are disclosed in Note 2 of the Company’s consolidated financial statements for the year ended December 31, 2025.
