CEO and CFO Comments

Mr. Xiang Li, chairman and chief executive officer of Li Auto, commented, “In the first quarter of 2024, our deliveries reached 80,400 vehicles, up 52.9% year over year, further solidifying Li Auto’s leadership position in the RMB300,000 and higher NEV market in China. In March, we launched and commenced delivery of our high-tech flagship family MPV, Li MEGA, which is also our first high-power charging BEV. Meanwhile, we accelerated our efforts to deploy super charging stations nationwide, adding charging resources for Li Auto users to expedite the 0-to-1 development phase of our high-power charging BEVs. In April, we launched and commenced delivery of Li L6, a five-seat premium family SUV, to satisfy the mobility needs of more young families, making all-wheel-drive range extension system and intelligent features available on vehicles priced below RMB300,000. As our company continues to grow amidst an ever-changing market landscape, we will embrace the twists and turns that the journey presents and consistently focus on enhancing operating efficiency while persistently creating incremental user value.”

Mr. Tie Li, chief financial officer of Li Auto, added, “Despite the rollout of a new model, product iterations, and pricing adjustments, our first quarter financial results remained solid. Our revenue reached RMB25.6 billion for the period, growing by 36.4% year over year, and our gross margin stayed healthy at 20.6%. While our first quarter deliveries fluctuated sequentially, we remain confident that our deliveries will continue to grow in the coming quarters. In line with this outlook, we have maintained the pace of our investments in research and development and sales and servicing network. Looking ahead, we will continue to rigorously evaluate and streamline our operations while being fully centered on users and products, driving progress toward our long-term goals and strategic vision amidst a competitive market.”

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 from operations, non-GAAP net income, non-GAAP net income attributable to ordinary shareholders, non-GAAP basic and diluted net earnings per ADS attributable to ordinary shareholders, non-GAAP basic and diluted net earnings 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 and release of valuation allowance on deferred tax assets, 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 GAAP and Non-GAAP Results” set forth at the end of this press release.
