PRC

Under the Enterprise Income Tax Law (“EIT Law”) in the PRC, domestic companies are subject to EIT at a uniform rate of 25%. The Company’s PRC subsidiaries, VIE and VIE’s subsidiaries are subject to the statutory income tax rate at 25% unless otherwise specified.

Under the EIT Law and its implementation rules, an enterprise established outside China with a “place of effective management” within China is considered a China resident enterprise for Chinese enterprise income tax purposes. A China resident enterprise is generally subject to certain Chinese tax reporting obligations and a uniform 25% enterprise income tax rate on its worldwide income. The implementation rules to the New EIT Law provide that non-resident legal entities are considered PRC residents if substantial and overall management and control over the manufacturing and business operations, personnel, accounting, properties, etc., occurs within the PRC. Despite the present uncertainties resulting from the limited PRC tax guidance on the issue, the Company does not believe that the legal entities organized outside the PRC should be treated as residents for 2008 EIT law purposes. If the PRC tax authorities subsequently determine that the Company and its subsidiaries registered outside the PRC are deemed resident enterprises, the Company and its subsidiaries registered outside the PRC will be subject to the PRC income tax at a rate of 25%. Dividends paid to non-PRC-resident corporate investor from profits earned by the PRC subsidiaries after January 1, 2008 would be subject to a withholding tax. The EIT law and its relevant regulations impose a withholding tax at 10%, unless reduced by a tax treaty or agreement, for dividends distributed by a PRC-resident enterprise to its non-PRC-resident corporate investor for earnings generated beginning on January 1, 2008. As of December 31, 2025 and June 30, 2026, there was no retained earnings from consolidated level of all the foreign subsidiaries.

As of June 30, 2026, the valuation allowance of RMB398,148 was related to the deferred income tax asset of the Group’s certain subsidiaries, VIEs and the VIEs’ subsidiaries established in PRC. These entities were in a cumulative loss position, which is a significant negative indicator to overcome that sufficient income will be generated over the periods in which the deferred income tax assets are deductible or utilized. The ultimate realization of deferred income tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible or utilized. Management considers the scheduled reversal of deferred income tax liabilities, projected future taxable income and tax planning strategies in making this assessment.

The net operating losses carry forwards of the Company’s PRC subsidiaries amounted to RMB538,346 as of June 30, 2026, of which RMB200,685, RMB111,893, RMB96,812, RMB89,821 and RMB39,135 will expire if unused by December 31, 2026, 2027, 2028, 2029 and 2030, respectively.
