Accounting Policies [Abstract]
Basis of presentation	Basis of presentation 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, 2023. 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 RMB610,321 and net cash outflows from operations of RMB416,811 for the six months ended June 30, 2024. As of June 30, 2024, the Group’s consolidated current liabilities exceeded current assets in the amount of RMB1,604,975. 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) obtaining extended financial support from controlling shareholder and related parties (iv) accelerating pace of collections of amounts due from related and third parties to optimize operational efficiency and (v) exploring opportunities for further equity financing. 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, 2024, the results of operations and cash flows for the six months ended June 30, 2023 and 2024, 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. Significant accounting estimates include, but are not limited to, service period of connectivity services; expected credit losses for accounts receivable, other non-current assets and amounts due from related parties; realizability of inventories; accrual for warranty obligations; useful lives and recoverability of property, equipment and intangible assets and right-of-use assets; recoverability of long-term investments; valuation allowance of deferred tax assets; fair values of share-based compensation awards, fair values of intangible assets acquired in an asset acquisition, fair value of convertible notes payables, warrant liabilities, incremental borrowing rates of the Group’s leases. Changes in facts and circumstances may result in these estimates to be revised. Actual results could differ from those estimates, and as such, differences may be material to the unaudited condensed consolidated financial statements.
Asset acquisition of Suzhou Photon-Matrix Optoelectronics Technology Co., Ltd (“Suzhou Photon Matrix”)	Asset acquisition of Suzhou Photon-Matrix Optoelectronics Technology Co., Ltd (“Suzhou Photon Matrix”)On January 31, 2024, the Group entered into share purchase agreements with existing third party shareholders of Suzhou Photon- Matrix, pursuant to which the Group acquired 13.10% additional equity interest in Suzhou Photon-Matrix for a total cash consideration of RMB46,306. Prior to the transaction, the Group held 49.17% equity interest in Suzhou Photon-Matrix and accounted for the interest as an equity method investment. As a result of the transactions, the Group’s equity interest increased to 62.27%, and the Group obtained control in Suzhou Photon- Matrix. The transaction was accounted for as an asset acquisition rather than a business combination as what the Group acquired does not include a substantive process that together with input to significantly contribute to the ability to create output. In determining the cost basis to be allocated to assets acquired, the Group measured its previously held equity interest and noncontrolling interest at their carrying values. The cost of assets acquired was allocated to the individual assets acquired or liabilities assumed based on their relative fair values.
Risks and concentration	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 and non-current assets. The Group’s policy requires cash and restricted cash to be placed with high quality financial institutions. The Group regularly evaluates the credit standing of the counterparties or financial institutions. The Group conducts credit evaluations on its customers prior to delivery of goods or services. The assessment of customer creditworthiness is primarily based on historical collection records, research of publicly available information and customer on site visits by senior management. Based on this analysis, the Group determines what credit terms, if any, to offer to each customer individually. If the assessment indicates a likelihood of collection risk, the Group will not deliver the services or sell the products to the customer or require the customer to pay cash to secure payment or to make significant down payments.
Fair value measurements	Fair value measurements Financial assets and liabilities of the Group primarily consist of cash, restricted cash, short-term investments, accounts receivable, amounts due from related parties, notes receivable, equity securities, short-term borrowings, accounts payable, notes payable, amounts due to related parties, warrant liabilities, convertible notes, and other payables included in accrued expenses and other current liabilities. The Group measures below assets and liabilities at fair value on a recurring basis by level within the fair value hierarchy as of December 31, 2023 and June 30, 2024 as below: Level 1 – Equity securities and public warrant liabilities using observable inputs in active markets; Level 3 – Private warrant liabilities using unobservable inputs.
Convenience translation	Convenience translationThe United States dollar (“US$”) amounts disclosed in the accompanying unaudited condensed consolidated financial statements are presented solely for the convenience of the readers. Translations of amounts from RMB into US$ for the convenience of the reader were calculated at the rate of US$1.00=RMB7.2672 , the certified noon buying rate set forth in the H.10 statistical release of the Federal Reserve Board on June 28, 2024. No representation is made that the RMB amounts could have been, or could be, converted into US$ at that rate on June 30, 2024, or at any other rate.

Warrants and Rights Note Disclosure [Abstract]

Warrant liabilities

ECARX Warrants in connection with the Merger

ECARX Public Warrants are publicly traded on Nasdaq, the liability is measured at fair value using observable inputs and categorized in Level 1 of the fair value hierarchy, while ECARX Private Warrant liability is measured at fair value using unobservable inputs and categorized in Level 3 of the fair value hierarchy. The Binomial Option Pricing Model with the following key assumptions is used for estimating the fair value of ECARX Private Warrants.


	As of December 31,		As of June 30,
	2023		2024
Risk-free rate of return (%)	3.93	%	4.47	%
Volatility	29.50	%	43.49	%
Expected dividend yield	0.0	%	0.0	%
Expected term	4.0 years		3.5 years
Fair value of the underlying ordinary shares	US$3.16 (equivalent to RMB22.44)		US$2.06 (equivalent to RMB14.97)

The risk-free rate of return was based on the yield of US Treasury Notes for the expected remaining life of the warrant liabilities. The Company estimates the volatility of its common stock using a binomial lattice model based on the price of public warrant as of the valuation date. Expected dividend yield is zero as the Company does not anticipate any dividend payments in the foreseeable future. Expected term to exercise the warrant liabilities is up to December 2027. The fair value of the Company’s ordinary shares was obtained from the listed trading price of ECX.

The table below reflects the movement of ECARX Warrants for the six months ended June 30, 2024:


	January 1, 2024 RMB	Addition RMB	Loss due to change in fair value RMB	Foreign exchange translation RMB	Settlement RMB	June 30, 2024 RMB

Accounting Policies [Abstract]

Summary of significant accounting policies

(a) Basis of presentation

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, 2023.

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 RMB610,321 and net cash outflows from operations of RMB416,811 for the six months ended June 30, 2024. As of June 30, 2024, the Group’s consolidated current liabilities exceeded current assets in the amount of RMB1,604,975.

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) obtaining extended financial support from controlling shareholder and related parties (iv) accelerating pace of collections of amounts due from related and third parties to optimize operational efficiency and (v) exploring opportunities for further equity financing. 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, 2024, the results of operations and cash flows for the six months ended June 30, 2023 and 2024, 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. Significant accounting estimates include, but are not limited to, service period of connectivity services; expected credit losses for accounts receivable, other non-current assets and amounts due from related parties; realizability of inventories; accrual for warranty obligations; useful lives and recoverability of property, equipment and intangible assets and right-of-use assets; recoverability of long-term investments; valuation allowance of deferred tax assets; fair values of share-based compensation awards, fair values of intangible assets acquired in an asset acquisition, fair value of convertible notes payables, warrant liabilities, incremental borrowing rates of the Group’s leases. Changes in facts and circumstances may result in these estimates to be revised. Actual results could differ from those estimates, and as such, differences may be material to the unaudited condensed consolidated financial statements.

(b) A combination between entities under common control

Acquisition of controlling interest in HF Tech Europe AB (“HF EU”)

On June 30, 2024, Ecarx Sweden AB. (“Ecarx SE”) acquired all issued and outstanding shares of HF Tech Europe AB (“HF EU”), an entity under common control, at a purchase consideration of SEK16,111 (equivalent to RMB10,854), which is subject to working capital adjustments and will be settled in December 2024. The unaudited condensed consolidated financial statements of the Company have been presented by combining assets, liabilities, revenues, expenses and equity of Ecarx and HF EU using the pooling-of-interests method as if the transaction occurred at the establishment date of HF EU on January 30, 2023. All intercompany transactions and balances between the combining entities have been eliminated.

The following table summarizes the results of operations and net assets of HF EU consolidated in these unaudited condensed consolidated financial statements. The amounts are after eliminating transactions between the Group and HF EU.

On January 31, 2024, the Group entered into share purchase agreements with existing third party shareholders of Suzhou Photon- Matrix, pursuant to which the Group acquired 13.10% additional equity interest in Suzhou Photon-Matrix for a total cash consideration of RMB46,306. Prior to the transaction, the Group held 49.17% equity interest in Suzhou Photon-Matrix and accounted for the interest as an equity method investment. As a result of the transactions, the Group’s equity interest increased to 62.27%, and the Group obtained control in Suzhou Photon- Matrix. The transaction was accounted for as an asset acquisition rather than a business combination as what the Group acquired does not include a substantive process that together with input to significantly contribute to the ability to create output. In determining the cost basis to be allocated to assets acquired, the Group measured its previously held equity interest and noncontrolling interest at their carrying values. The cost of assets acquired was allocated to the individual assets acquired or liabilities assumed based on their relative fair values.

(d) 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 and non-current assets.

The Group’s policy requires cash and restricted cash to be placed with high quality financial institutions. The Group regularly evaluates the credit standing of the counterparties or financial institutions.

The Group conducts credit evaluations on its customers prior to delivery of goods or services. The assessment of customer creditworthiness is primarily based on historical collection records, research of publicly available information and customer on site visits by senior management. Based on this analysis, the Group determines what credit terms, if any, to offer to each customer individually. If the assessment indicates a likelihood of collection risk, the Group will not deliver the services or sell the products to the customer or require the customer to pay cash to secure payment or to make significant down payments.

Factoring agreement

In March 2024, the Group entered into an accounts receivable factoring agreement with a finance company of Geely Group with a minimum interest rate of 6.0% per annum. The one-year factoring agreement provides the Group to have access to up to RMB149,000 on a revolving basis, measured by the aggregate amount advanced for the unpaid balance of certain trade accounts receivable from specified customers from time to time.

The Group accounts for transfers of accounts receivable in accordance with ASC 860, Transfers and Servicing (“ASC 860”). Pursuant to ASC 860, the Group does not derecognize customers’ accounts receivable when receiving advance payment from the finance company due to the recourse obligations retained by the Group. As of June 30, 2024, factoring accounts receivable of RMB186,250 were not derecognized and were restricted as security for the advanced amounts of RMB149,000 received by the Group, which were recorded as amounts due to related parties on the unaudited condensed consolidated balance sheets. The factoring proceeds from the finance company was considered financing activities and reported as “Borrowings from related parties” on the unaudited condensed consolidated statements of cash flows.

Share-Based Payment Arrangement [Abstract]

Share based compensation

(a) Restricted Share Unit (“RSU”)

2022 Share Incentive Plan

In February 2024, the Company granted an aggregated number of 117,250 RSUs to employees, which were immediately fully vested upon the grants and these RSUs had been fully exercised as of February 29, 2024.

The following table summarizes activities of the Company's RSUs for the six months ended June 30, 2024:


	Number of RSUs	Weighted Average Exercise Price	Weighted Average Fair value at grant date	Weighted remaining contractual years	Aggregate intrinsic value
		US$	US$
Outstanding at January 1, 2024	15,033,854	0.69	4.91
Granted (new RSUs)	117,250	—	3.51
Exercised	(4,039,195)	0.03	—
Outstanding at June 30, 2024	11,111,909	0.92	4.31
Vested and expected to vest as of June 30, 2024	11,111,909	0.92	4.31	8.81	38,054
Exercisable as of June 30, 2024	9,185,844	0.92	4.26	8.93	31,602

Total intrinsic value of RSUs exercised was RMB22,449 for the six months ended June 30, 2024.

The fair value of the RSUs granted in 2024 under 2022 Share Incentive Plan is estimated using the closing price as of the grant dates of listed trading price of the Company.

(b) Options

2022 Share Incentive Plan

In April 2024, the Company granted an aggregate number of 4,960,570 share options to employees. The share options vest under one of the following two approaches:

•fully vested on the date of grant.

•25% of the grants vest every twelve-month service period since the service commencement of the employees.

The following table summarizes activities of the options for the six months ended June 30, 2024:


	Number of RSUs	Weighted Average Exercise Price	Weighted Average Fair value at grant date	Weighted remaining contractual years	Aggregate intrinsic value
		US$	US$
Outstanding at January 1, 2024	11,260,718	9.62	3.11
Granted	4,960,570	0.50	1.21
Forfeited	(195,628)	7.36	2.86
Outstanding at June 30, 2024	16,025,660	6.82	2.52
Vested and expected to vest as of June 30, 2024	16,025,660	6.82	2.52	8.02	—
Exercisable as of June 30, 2024	10,884,902	8.66	2.76	7.49	—

The fair value of the options granted for the six months ended June 30, 2023 and 2024 are estimated using the binomial model with the following assumptions used:


	Six Months Ended June 30,
	2023		2024
Risk-free rate of return	3.79	%	4.69	%
Volatility	44.95	%	47.25	%
Expected dividend yield	0.0	%	0.0	%
Fair value of underlying ordinary share	US$8.02		US$1.64
Expected terms	10 years		10 years

The expected volatility was estimated based on the historical volatility of comparable peer public companies with a time horizon close to the expected term of the option awards. The risk-free interest rate was separately estimated based on the yield to maturity of U.S. Treasury bonds for a term consistent with the expected term of the options in effect at the valuation date. Expected dividend yield is zero as the Group does not anticipate any dividend payments in the foreseeable future. Expected term is the contract life of the option awards.

Compensation expenses recognized for RSUs and options for the six months ended June 30, 2023 and 2024 were allocated as follows.


	Six Months Ended June 30,
	2023	2024
	RMB	RMB
Selling, general and administrative expenses	32,565	55,066
Research and development expenses	19,661	15,859
Total	52,226	70,925

As of June 30, 2024, US$9,290 (equivalent to RMB66,196) of the total unrecognized compensation expense related to RSUs and options is expected to be recognized over a weighted-average period of 1.2 years. The unrecognized compensation cost may be adjusted for actual forfeitures occurring in the future.

Nil and RMB6,446 impairment loss were recognized for the six months ended June 30, 2023 and 2024, respectively.

As disclosed in Note 1(c), the Group acquired 13.10% additional equity interest in Suzhou Photon-Matrix from existing shareholders and thereafter the Group obtained control of Suzhou Photon-Matrix and derecognized the equity method investment with carrying amount of RMB34,829.

In May 2024, Hubei Dongjun Automotive Electronic Technology Co., Ltd. ("Hubei Dongjun”) distributed on a pro rata basis its equity interest in Shenzhen U Chance Technology Co., Ltd. (“U Chance”) to each of its equity holders, namely the Group and Hubei Dongjun Industrial and Commercial Co., Ltd. based on their respective shareholding. As a result, U Chance was spun-off from Hubei Dongjun and the Group directly held 49% equity interest in U Chance. The Group continues to account for its investment in U Chance as equity method investment at its carrying amount.

Equity securities measured at fair value

The fair value of 2,030,374 shares of Luminar Technologies, Inc. decreased to US$3,025 (equivalent to RMB21,985) as of June 30, 2024. The fair value change of US$3,773 (equivalent to RMB27,421) was recorded as a loss in the unaudited condensed consolidated statements of comprehensive loss.
