CEO and CFO Comments

Mr. Xiang Li, chairman and chief executive officer of Li Auto, commented, “Amid intense market competition and a major model refresh cycle, Li Auto remained the best-selling domestic automotive brand in China’s RMB200,000-and-above NEV market in the first half of 2026. We have completed the upgrade of Li L series and are now refreshing our BEV lineup. Notably, the new Li L6 generated robust order flow, and we are confident that it will carry on the success of the Li i6 and reinforce our leading position in the RMB200,000-to-300,000 SUV market. Our enhanced product portfolio positions us well for growth. Backed by our unwavering user-centric product philosophy and leading in-house technologies, we will continue to pursue product excellence, expand our global footprint, and forge a sustainable path toward long-term value creation.”

Mr. Tie Li, chief financial officer of Li Auto, added, “In the second quarter of 2026, our gross margin improved sequentially to 11.0%, benefiting from the launch of the all-new Li L9. We anticipate further margin expansion for the second half of the year as our product mix optimizes, with a higher sales contribution from the Livis trim and the launch of refreshed BEV models and Li i9. Coupled with a sustained focus on operational efficiency, we expect our bottom-line to improve gradually. Balancing growth and profitability through disciplined capital allocation, we will steadfastly execute our core strategies in product innovation, technological advancement, and global expansion to secure our future competitiveness.”

Non-GAAP Financial Measures

The Company uses non-GAAP financial measures, such as non-GAAP cost of sales, non-GAAP research and development expenses, non-GAAP selling, general and administrative expenses, non-GAAP income/(loss) from operations, non-GAAP net income/(loss), non-GAAP net income/(loss) attributable to ordinary shareholders, non-GAAP basic and diluted net earnings/(loss) per ADS attributable to ordinary shareholders, non-GAAP basic and diluted net earnings/(loss) per share attributable to ordinary shareholders and free cash flow, in evaluating its operating results and for financial and operational decision-making purposes. By excluding the impact of share-based compensation expenses, the Company believes that the non-GAAP financial measures help identify underlying trends in its business and enhance the overall understanding of the Company’s past performance and future prospects. The Company also believes that the non-GAAP financial measures allow for greater visibility with respect to key metrics used by the Company’s management in its financial and operational decision-making.

The non-GAAP financial measures are not presented in accordance with U.S. GAAP and may be different from non-GAAP methods of accounting and reporting used by other companies. The non-GAAP financial measures have limitations as analytical tools and when assessing the Company’s operating performance, investors should not consider them in isolation, or as a substitute for financial information prepared in accordance with U.S. GAAP. The Company encourages investors and others to review its financial information in its entirety and not rely on a single financial measure.

The Company mitigates these limitations by reconciling the non-GAAP financial measures to the most comparable U.S. GAAP performance measures, all of which should be considered when evaluating the Company’s performance.

For more information on the non-GAAP financial measures, please see the table captioned “Unaudited Reconciliation of U.S. GAAP and Non-GAAP Results” set forth at the end of this press release.
