Valuation Techniques

Investment securities: The Group invested in a listed equity securities, ECARX, and values the equity securities using quoted prices for the underlying securities in active markets. Accordingly, the Group classifies the valuation technique that use these inputs as Level 1.

Derivative asset: Derivative asset represents forward currency contracts. The fair value is estimated by discounting the difference between the contractual forward price and the current available forward price for the residual maturity of the contract using observable market rates.

Securities pledged to an investor: The estimated fair values of the securities are determined using available market information. Accordingly, the Group classifies the valuation technique that use these inputs as Level 1.

Put option liabilities, exchangeable notes and convertible notes: As the Group’s put option liabilities, exchangeable notes and convertible notes are not traded in an active market with readily observable quoted prices, the Group uses significant unobservable inputs (Level 3) to measure the fair value of the put option liabilities, exchangeable notes and convertible notes at inception and at each subsequent balance sheet date. See Notes 13, 14 and 15 for information about the significant unobservable inputs used in the respective fair value measurements.

Public Warrants and Sponsor Warrants: As of December 31, 2025, Public Warrants and Sponsor Warrants are classified as Level 1 due to the use of the observed trading price. As of December 31, 2024, Public Warrants is classified as Level 1 due to the use of the observed trading price, while Sponsor Warrants is classified as Level 3 due to the use of the significant unobservable inputs (Level 3) used in the fair value measurements (Note 12).

The other financial assets and liabilities of the Group primarily consist of cash and cash equivalents, restricted cash, accounts receivable, loan receivables and other receivables included in prepayments and other current assets and other non-current assets, short-term borrowings, accounts payable, other payables included in accrued expenses and other current liabilities and other non-current liabilities and operating lease liabilities. As of December 31, 2025 and 2024, the fair values of operating leases liabilities approximated to their carrying values, which were due to that the underlying interest rates approximated to the market rates for similar instruments with similar maturities, and the carrying amounts of other financial instruments approximated to their fair values, which were due to short term maturity of these instruments.

The Group’s non-financial assets, such as property, equipment and software and intangible assets, would be measured at fair value only if they were determined to be impaired.
