CEO and CFO Comments

Mr. Xiang Li, founder, chairman, and chief executive officer of Li Auto, commented, “Fueled by our comprehensive capabilities in R&D, supply chain, and intelligent manufacturing, we executed on our product roadmap and delivered another quarter with meaningful progress. Our Li L9 deliveries exceeded 10,000 in the first full month of its production despite the uncertain macro environment and supply chain disruptions. Li L9 has been the sales champion among full-size SUVs in China since its deliveries started. Such a strong performance demonstrated the wide recognition by family users and our team’s formidable execution capabilities. Meanwhile, we forged ahead with the launch of Li L8, the successor to Li ONE, and unveiled Li L7, a five-seat flagship family SUV.”

“To create successful products, we have two core goals. Firstly, for consumers, we choose to exceed their needs rather than merely meeting them. Secondly, as a company, we aim to achieve healthy gross margin and self-sustaining cash flow, which will allow us to continually invest in our dual growth engines of R&D and business capabilities. Specifically, our R&D efforts will be directed more comprehensively across products, platforms, and systems, with the long-term goal of growing into a world-class technology company. Our business capabilities include commercial, supply, and organization capabilities. With continued investments in R&D and business capabilities supported by our healthy gross margin, we will continue to pursue product and commercial success and foster a healthy long-term development model. This flywheel has been the strategic focus since our founding and, we believe, will remain our strategy going forward. By understanding this business model, you will understand Li Auto.”

Mr. Tie Li, chief financial officer of Li Auto, added, “In the third quarter, we navigated our model succession and launch cycle, as well as a challenging macro environment and cost inflation. Against this backdrop, our third quarter revenues came in at RMB9.34 billion, up 20.2% year over year. Our gross margin was 12.7% during the quarter, affected by a provision related to Li ONE, despite the healthy vehicle margin we achieved for Li L9 in its first quarter of production. Looking ahead, we are optimistic that with rapid production ramp-up, rigorous execution, and responsible cost management, we will realize greater economies of scale and further drive down costs, putting us back on track to hit our profitability inflection point. As always, we believe that our ability to deliver best-in-class products will keep Li Auto at the forefront of the NEV transformation.”

Non-GAAP Financial Measure

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 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 net loss or other consolidated statements of comprehensive loss data 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 GAAP and Non-GAAP Results” set forth at the end of this press release.
