ECARX Holdings Inc.

PRELIMINARY NOTE

Our unaudited condensed consolidated financial statements as of and for the six-months ended June 30, 2025 and June 30, 2024, included herein, are prepared in accordance with accounting principles generally accepted in the United States of America and are reported in U.S. dollars (“US$”). These should be read in conjunction with our audited financial statements as of and for the year ended December 31, 2024 filed with the U.S. Securities and Exchange Commission (the “SEC”) on Form 20-F on March 26, 2025 (the “2024 Annual Report”).

During the six-months ended June 30, 2025, we decided to change our reporting currency from Chinese Renminbi (“RMB”) to U.S. dollars. This change was made as a result of our assessment and conclusion that the change will help provide a clearer understanding of our financial performance to investors and improve comparability of our performance to peers, particularly due to our ongoing international expansion.

The change in our reporting currency is a voluntary change and is accounted for retrospectively. The unaudited condensed consolidated financial statements appended herewith for all periods presented have been translated into the new reporting currency as if we have always used U.S. dollars as the reporting currency.
