The accompanying unaudited condensed consolidated financial statements of ECARX Holdings Inc. (“the Company”) and its consolidated subsidiaries (the “Group”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted as permitted by rules and regulations of the United States Securities and Exchange Commission. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements of the Group as of and for the year ended December 31, 2025.

The accompanying unaudited condensed consolidated financial statements were prepared assuming the Group will continue as a going concern. The Group generated a net loss of US$23,001 and net cash outflows from operations of US$127,695 for the six months ended June 30, 2026. As of June 30, 2026, the Group’s consolidated current liabilities exceeded current assets in the amount of US$271,385.

The Company has evaluated plans to continue as a going concern which include, but are not limited to, (i) reducing discretionary capital and operating expenses; (ii) obtaining additional facilities from banks and renewal of existing bank borrowings; (iii) issuance of new equity and convertible debt securities; (iv) obtaining extended financial support from controlling shareholder and related parties; and (v) accelerating pace of collections of amounts due from related and third parties to optimize operational efficiency.

Notwithstanding this, feasibility of some of these plans is contingent upon factors outside of the control of the Company and, as such, the Company concluded that substantial doubt about its ability to continue as a going concern has not been alleviated as of the reporting date.

In the opinion of the management, all adjustments (which include normal recurring adjustments) necessary to present a fair statement of the financial position as of June 30, 2026, the results of operations and cash flows for the six months ended June 30, 2025 and 2026, have been made.

The preparation of unaudited condensed consolidated financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, related disclosures of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements and reported revenues and expenses during the periods presented in the unaudited condensed consolidated financial statements and accompanying notes.

Risks and concentration

Concentration of credit risk

Financial instruments that potentially expose the Group to concentrations of credit risk consist principally of cash, restricted cash, short-term investments, accounts receivables, notes receivable, amounts due from related parties, other receivables included in prepayments and other current assets and other non-current assets.

Fair value measurements

The Group measures certain assets and liabilities at fair value. Fair value is the exit price, or the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. The fair value hierarchy is based on inputs to valuation techniques that are used to measure fair value that are either observable or unobservable. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources while unobservable inputs reflect a reporting entity’s pricing based upon their own market assumptions.

The fair value hierarchy consists of the following three levels:

Level 1 — Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.

Level 2 — Includes other inputs that are directly or indirectly observable in the marketplace.

Level 3 — Inputs are derived from valuation techniques in which one or more significant inputs or value drivers are unobservable.
