As disclosed in Note 8, the Group’s available-for-sale debt security investments include investments the Group made in private companies which contains substantive redemption and preferential rights. The Group’s equity securities investments measured using fair value option include an investment the Group made in a private company which contains certain preferential rights. Such investments are classified within Level 3 for fair value measurement. As of December 31, 2024 and June 30, 2025, the carrying value of the investments were RMB1,277,068 and RMB1,278,557, respectively. The Group re-measured the respective fair values using a market approach by adopting a backsolve method, which determined the estimated fair value of the investments through comparison to a recent transaction and applied significant unobservable inputs and assumptions. For the six months ended June 30, 2024 and 2025, fair value changes of available-for-sale debt security investments and equity securities investments using fair value option were not material. The significant unobservable inputs adopted in the valuation as of December 31, 2024 and June 30, 2025 are as follows:

​

As disclosed in Note 19, the warrants issued by PE CNHC in May 2024 are not traded in an active securities market. As such, the Company estimated its fair value using the binomial option pricing model as of June 30, 2025 using the assumptions including fair value per share, dividend yield, time to maturity, risk free interest rate and expected volatility. As of June 30, 2025, the carrying value of the warrant was not material.

Financial assets and liabilities of the Group primarily consist of cash and cash equivalents, restricted cash, short-term investments, trade receivables, amounts due from related parties, deposits and other receivables, available-for-sale debt security investments, retained asset - backed securities, trade and notes payable, amounts due to related parties, other payables, derivative instruments, short-term borrowings, lease liabilities and long-term borrowings. As of December 31, 2024 and June 30, 2025, other than as discussed above, the carrying values of these financial instruments approximated to their respective fair values.

The estimated useful lives are as follows:

​

The cost of maintenance and repairs is expensed as incurred, whereas the cost of renewals and betterment that extends the useful lives of property, plant and equipment is capitalized as additions to the related assets. Interest expense on outstanding debt is capitalized during the period of significant capital asset construction. Capitalized interest on construction-in-progress is included within property, plant and equipment and is amortized over the useful life or units of production of the related assets. When assets are retired or otherwise disposed of, the cost and related accumulated depreciation and amortization are removed from their respective accounts, and any gain or loss on such sale or disposal is reflected in the consolidated statements of comprehensive loss.

Available-for-sale debt security investments are reported at estimated fair value with the aggregate unrealized gains and losses, net of tax, reflected in accumulated other comprehensive loss in the consolidated balance sheets. Gain or losses are realized when the investments are sold or when dividends are declared or payments are received. If the amortized cost basis of an available-for-sale security exceeds its fair value and if the Company has the intention to sell the security or it is more likely than not that the Company will be required to sell the security before recovery of the amortized cost basis, an impairment is recognized in the consolidated statements of comprehensive loss. If the Company does not have the intention to sell the security and it is not more likely than not that the Company will be required to sell the security before recovery of the amortized cost basis and the Company determines that the decline in fair value below the amortized cost basis of an available-for-sale security is entirely or partially due to credit-related factors, the credit loss is measured and recognized as an allowance for credit losses in the consolidated statements of comprehensive loss. The allowance is measured as the amount by which the debt security’s amortized cost basis exceeds the Company’s best estimate of the present value of cash flows expected to be collected.

Held-to-maturity debt security investment are reported at amortized cost. The securities are held to collect contractual cash flows, and the Group has the positive intent and ability to hold those securities to maturity.

Trading securities are acquired and held principally for the purpose of selling them. The securities are reported at fair value, and subsequent changes in the fair value are recognized through net income.

The Group monitors its investments measured under equity method for other-than-temporary impairment by considering factors including, but not limited to, current economic and market conditions, the operating performance of the companies including current earnings trends and other company-specific information. No impairment charge was recognized for the six months ended June 30, 2024 and 2025.

The following table shows a reconciliation in the current reporting period related to carried-forward warranty liabilities:

Vehicle sales

The Group generates revenue from sales of electric vehicles, together with a number of embedded products and services through a series of contracts. The Group identifies the users who purchase the vehicle as its customers. In general, there are multiple distinct performance obligations explicitly stated in a series of contracts in addition to sales of vehicles, which may include home chargers, vehicle connectivity services, extended warranty services and battery swapping services, some of which are only granted to certain initial users. These multiple distinct performance obligations are accounted for in accordance with ASC 606. The standard warranty provided by the Group is accounted for in accordance with ASC 460, Guarantees, and the estimated costs are recorded as a liability when the Group transfer the control of vehicle to a user.

In the instance that customers only pay the amount after deducting the government subsidies to which they are entitled for the purchase of electric vehicles, the government subsidies are applied and collected by the Group or Jianghuai Automobile Group Co., Ltd. (“JAC”) from the government on behalf of the customers. The government subsidy is considered as a part of the transaction price it charges the customers for the electric vehicle, as the subsidy is granted to the buyer of the electric vehicle instead of the Group and the buyer remains liable for such amount to the Group in the event the subsidies were not received by the Group.

In the instance that some eligible customers elect installment payment for battery or the auto financing arrangements, the Group believes such arrangement contains a significant financing component and as a result adjusts the transaction price to reflect the impact of time value on the transaction price using an appropriate discount rate (i.e. the interest rates of the loan reflecting the credit risk of the borrower). Interest income from such arrangements with a significant financing component is presented as other sales. Receivables related to the battery installment payment and auto financing programs that are expected to be repaid by customers beyond one year of the dates of the financial statements are recognized as non-current assets. The difference between the gross receivable and the respective present value is recorded as unrealized finance income. Interest income from such arrangements with a significant financing component is presented separately from revenue from contracts with customers.

The Group generally determines standalone selling prices based on the prices charged to customers. If the standalone selling price is not directly observable, it is estimated using expected cost plus a margin or adjusted market assessment approach, considering the Group’s pricing policies and practices, and the data utilized in making pricing decisions. The overall contract price is then allocated to each distinct performance obligation based on the relative estimated standalone selling price in accordance with ASC 606. The revenue for vehicle sales and home chargers are recognized at a point in time when the control of the product is transferred to the customer. For the vehicle connectivity services and battery swapping services, the Group recognizes the revenue over time using a straight-line method during the estimated beneficial period. For the performance obligations which are only granterd to initial owners, the estimated beneficial period is based on the estimated length of time that the initial owner owns the vehicles before it is re-sold to secondary market. As for the extended warranty services, given limited operating history and lack of sufficient historical data, the Group decides to recognize the revenue over time based on a straight-line method initially, and will continue monitoring the cost pattern periodically and adjust the revenue recognition pattern to reflect the actual cost pattern as it becomes available.

As the consideration for the vehicle and all embedded services are generally paid in advance, which means the payments received are prior to the transfer of goods or services by the Group, the Group records a contract liability (deferred revenue) for the allocated amount regarding those unperformed obligations. As of December 31, 2024 and June 30, 2025, the balances of contract liabilities (deferred revenue) from vehicle sales contracts were RMB6,349,012 and RMB6,236,488, respectively.

Battery as a Service (BaaS)

The Battery as a Service (the “BaaS”), allows users to purchase electric vehicles without batteries and subscribe for the usage of batteries separately. In PRC, under the BaaS, the Group sells batteries to Wuhan Weineng Battery Asset Co., Ltd. and its subsidiaries (the “Battery Asset Company”), an equity investee of the Group, on a back-to-back basis when the Group sells the vehicle to the BaaS users and the BaaS users subscribe for the usage of the batteries from the Battery Asset Company by paying a monthly subscription fee to the Battery Asset Company. The promise to transfer the control of the batteries to the Battery Asset Company is the only performance obligation in the contract with the Battery Asset Company for the sales of batteries. The Group recognizes revenue from the sales of batteries to the Battery Asset Company when the vehicles (together with the batteries) are delivered to the BaaS users which is the point that control of the batteries is transferred to the Battery Asset Company.

Together with the sales of the batteries, the Group entered into service agreements with the Battery Asset Company, pursuant to which the Group provides services to the Battery Asset Company including batteries monitoring, maintenance, upgrade, replacement, IT system support, etc., with monthly service charges. In case of any default in payment of monthly rental fees from users, the Battery Asset Company also has right to request the Group to track and lock down the battery subscribed by the users to limit its usage. In addition, in furtherance of the BaaS, the Group agreed to provide guarantee to the Battery Asset Company for the default in payment of monthly subscription fees from users. The maximum amount of guarantee that can be claimed by the Battery Asset Company for the users’ payment default shall not be higher than the accumulated service fees the Group receives from the Battery Asset Company.

For services provided to the Battery Asset Company, revenue is recognized over the period when services are rendered. As for financial guarantee liabilities, the provision of guarantee is linked to and associated with services rendered to the Battery Asset Company and the payment of guarantee amount is therefore accounted for as the reduction to the revenue from the Battery Asset Company.

The fair value of the guarantee liabilities is determined by taking considerations of the default pattern of the Group’s existing battery installment programs provided to users. At each period end, the financial liabilities are remeasured with the corresponding changes recorded as the reduction to the revenue. For the six months ended June 30, 2024 and 2025, both service revenue and guarantee liability were immaterial.

Since 2022, the BaaS users are also provided with the option to buy out the batteries in PRC. Under this arrangement, BaaS users and the Battery Asset Company enter into battery subscription termination agreement, and the Group purchases the outgoing batteries from the Battery Asset Company, after which the Group sells batteries with qualified performance to the BaaS users. These transactions are arranged on back-to-back basis under which the Group is in substance rendering the agency service to facilitate the BaaS users which are also the customers of the Group to complete the purchase of batteries from the Battery Asset Company. The Group therefore recognizes revenue of the service to facilitate the BaaS batteries buy out transactions on net basis with the amount of the difference between the consideration the Group receives from the BaaS users for the battery sales and the price of batteries the Group pays to the Battery Asset Company. Upon the completion of BaaS buy-out, the Group stops to provide battery service and is not obliged to provide guarantee and warranty related to the relevant batteries to the Battery Asset Company.

Practical expedients and exemptions

The Group follows the guidance on immaterial promises when identifying performance obligations in the vehicle sales contracts and concludes that certain value-added services are not performance obligations considering that they are not critical items for vehicle driving and the usage of these services are expected to be very limited. The Group also performs an estimation on the standalone fair value of each promise applying a cost plus margin approach and concludes that the standalone fair value of these services are insignificant individually and in aggregate, representing less than 3% of vehicle gross selling price and aggregate fair value of each individual promise.

Parts, accessories and after-sales vehicle services

The Group sells parts and accessories to the third party authorized service centers and its users, and provides after-sales vehicle services to users, including, repair, maintenance, extended warranty services and other vehicle services. Revenue from the sales of parts and accessories is recognized when the control of the products is transferred to the customers. Revenue from after-sales services is recognized when the services are rendered.

Provision of power solutions

The Group provides power solutions to users, including sale of charging piles, provision of battery charging and swapping services, battery upgrade service, BaaS battery buy-out service and other power solution services. Revenue from the services is recognized when relevant services are rendered. Revenue from the sales of charging piles is recognized when the control of the products is transferred to the customers.

Battery swapping service

The Group provides battery swapping service to users with convenient “recharging” experience by swapping the user’s battery for another one. The battery swapping service is in substance a charging service instead of non-monetary exchanges or sales of batteries as the batteries involved in such swapping are the same in capacity and very similar in performance.

For performance obligation of the battery swapping service sold together with the vehicles (i.e. monthly free-of-charge quota), the Group recognizes the revenue over time using a straight-line method in the estimated beneficial period, being the estimated length of time that the initial owner owns the vehicle. For the battery swapping beyond monthly free-of-charge quota for which additional considerations are paid by the users, the Group recognizes revenue when the battery swapping service is completed.

Battery upgrade service

The Group provides battery upgrade service to both BaaS users and non-BaaS users. The users can exchange their batteries with lower capacity for the batteries with higher capacity from the Group with a fixed cash consideration. The battery upgrade service is in substance the provision of incremental battery capacity service to the users instead of non-monetary battery exchanges or sales of battery. Therefore, under non-BaaS model, the revenue from the battery upgrade service is recognized at the amount of cash consideration paid by users at a point in time when the service is rendered. Under the BaaS model, since the ownership of originally installed battery belongs to the Battery Asset Company, when a user requests battery upgrade, the Group actually upgrades the battery that belongs to the Battery Asset Company and recognize revenue for the battery upgrade service at the amount paid by the Battery Asset Company when upgrade service is rendered. BaaS users will then pay a higher monthly subscription fee to the Battery Asset Company for subscribing for the battery with higher capacity.

Others

Other revenues consists of sales of used vehicles, auto financing services, technical services, retail merchandise, automotive regulatory credits, embedded products and services offered together with vehicle sales, including vehicle connectivity services, and other products and services. Revenue is recognized when relevant services are rendered or control of the products is transferred.

Technical services

The Group provides a range of technical services to customers, including technologies licensing, engineering, development, testing, sourcing, support and consultancy services. Revenue from technical services is recognized when relevant services are rendered.

Among these services, the Group generates revenue from providing a non-exclusive, non-transferable and sublicensable worldwide license of the Group’s existing and future iteration of technical information, technical solutions, software and intellectual property rights in relation to its electric vehicle platform (collectively referred to as the “Licensed Technologies”) to a related party and its affiliates. The consideration agreed includes one-time fixed amount of license fee plus royalties determined based on licensed products sold by licensee in the future. The functionality of the Licensed Technologies granted to this related party is expected to substantively change during the license period, and the related party is practically required to use the updated Licensed Technologies. This arrangement is considered as one performance obligation to provide access to the Group’s technology, which is continuously developed and upgraded by the Group over the license period. The license fee is recognized in revenue on a straight-line basis over the license period and the sales-based royalties is recognized when the subsequent sale occurs.

Sales of automotive regulatory credits

New Energy Vehicle (“NEV”) mandate policy launched by China’s Ministry of Industry and Information Technology (“MIIT”) specifies the NEV credit targets and as all of the Group’s products are NEVs, the Group is able to generate NEV credits above target. The credits earned per vehicle is dependent on various metrics such as vehicle driving range and battery energy efficiency, and is calculated based on the MIIT published formula. Excess positive NEV credits are tradable to other vehicle manufacturers through a credit management system established by the MIIT on a separately negotiated basis. The Group sells these credits at agreed price to other vehicle manufacturers.

Considerations for automotive regulatory credits are typically received at the point control transfers to the customer, or in accordance with payment terms customary to the business. The Group recognizes revenue on the sale of automotive regulatory credits at the time control of the regulatory credits is transferred to the purchasing party as other sales revenue in the consolidated statements of comprehensive loss.

Incentives

The Group frequently offers NIO points, a self-managed customer loyalty program, and coupons under various scenarios, which can be redeemed to acquire free or discounted goods or services provided by the Group, including accessories, branded merchandise and other services etc. The major accounting policy for those incentives is described as follows:

(i) Incentives in connection with sales transactions

NIO points and coupons granted in connection with the sales transaction that provide a material right to the customer give rise to a separate performance obligation according to ASC 606, and are taken into consideration when allocating the transaction price of the sales. The Group determines the standalone selling price of each point or coupon based on estimated incremental discount adjusted for redemption probability, which is estimated based on the historical redemption pattern. The amount allocated to the NIO points and coupons as separate performance obligation is recorded as contract liability (deferred revenue) and revenue should be recognized when future goods or services are transferred or when the NIO points and coupons expire.

A coupon that can be applied against amounts owed to the Group in a future sale transaction is consideration payable to a customer, which is accounted for as a reduction of the transaction price and, therefore, of revenue.

(ii) Incentives in other scenarios

NIO points and coupons are also granted for encouraging user engagement and generating market awareness, such as inviting friends to test drive or purchase a vehicle, frequent sign-ins to the Group’s mobile application, participating in community activities, etc. The Group accounts for such NIO points and coupons as selling, general and administrative expenses with a corresponding liability recorded under other current liabilities of its consolidated balance sheets upon the NIO points and coupons are granted. The Group estimates the liabilities based on cost of the products and services that can be redeemed, and its estimate of probability of redemption. At the time of redemption, the Group records a reduction of inventory and other current liabilities. In certain cases where merchandise is sold for cash in addition to NIO points, the Group records revenue of other sales for the amount of cash received.

For the six months ended June 30, 2024 and 2025, the revenue portion allocated to the NIO points and coupons as a separate performance obligation was RMB708,482 and RMB640,036, respectively, which is recorded as contract liability (deferred revenue). For the six months ended June 30, 2024 and 2025, the total NIO points and coupons recorded as selling, general and administrative expenses was RMB122,704 and RMB122,196, respectively.

As of December 31, 2024 and June 30, 2025, liabilities recorded related to unredeemed NIO points and coupons were RMB2,017,516 and RMB2,112,784, respectively.
