EXPLANATORY NOTE

Commencing with its fiscal year beginning January 1, 2025, Amber International Holding Limited (the “Company”) will begin reporting its results and will prepare its financial statements in accordance with International Financial Reporting Standards (“IFRS”) issued by the International Accounting Standards Board as oppose to United States Generally Accepted Accounting Principles (“US GAAP”), which was previously followed. Some prior year information will be restated in accordance with IFRS. Such restated information relates solely to the Company’s transition to IFRS, and there were no prior material errors, corrections or misstatements in the Company’s previously issued financial statements prepared in accordance with US GAAP.

The change is to align with the reporting and preparation of the financial statements of Amber DWM Holding Limited, which was treated as the “acquirer” company for financial reporting purpose in connection with the business combination completed by the Company as of March 12, 2025 (the “Business Combination”). Immediately following the Business Combination, Amber DWM Holding Limited became a subsidiary of the Company.
