CEO and CFO Comments

“In the first quarter of 2026, the Company delivered 83,465 smart electric vehicles, representing a year-over-year increase of 98.3%. Starting from the second quarter, the Company has entered an intensive new product launch and delivery cycle. We expect total deliveries in the second quarter to range between 110,000 and 115,000 vehicles, with a year-over-year growth of 52.7% to 59.6%,” said William Bin Li, founder, chairman, and chief executive officer of NIO.

“After eleven years of sustained investment and dedication, the Company has built comprehensive systematic innovation capabilities, serving as the core foundation for us to continuously launch innovative products and strengthen our long-term competitiveness. The NIO All-New ES8 has ranked first in sales in both China’s large SUV segment and the segment priced above RMB 400,000 for five consecutive months. The NIO ES9, our flagship executive SUV, integrates multiple industry-first technologies and class-leading features, and is poised to lead the premium flagship executive SUV segment into the battery electric era. This year, powered by NIO’s in-house developed smart driving chip, NIO WorldModel and the full-domain vehicle operating system, ONVO’s new models will undergo comprehensive upgrades in smart technologies, continuously enhancing user experience. The recently launched ONVO L80, ONVO’s flagship large five-seat SUV, caters to broader user needs through innovative space and lifestyle design. FIREFLY will continue to launch special edition models to deepen emotional connections with users,” added William Bin Li.

"In the first quarter of 2026, our vehicle margin stood at 18.8%, improving quarter-over-quarter for four consecutive quarters. Other sales margin reached 20.6%, a four-year high, supported by the expanding scale and improving profitability of our services and community-related businesses as our user base continues to grow. We also maintained positive non-GAAP operating profit in the quarter, and cash reserves continued to increase,” said Stanley Yu Qu, NIO’s chief financial officer. “We are encouraged by the continued improvement across all key operating metrics. Looking ahead, we will further enhance cost and operational efficiency while strengthening our sustainable business capabilities.”

Non-GAAP Disclosure

The Company uses non-GAAP measures, such as adjusted cost of sales (non-GAAP), adjusted research and development expenses (non-GAAP), adjusted selling, general and administrative expenses (non-GAAP), adjusted profit/(loss) from operations (non-GAAP), adjusted net profit/(loss) (non-GAAP), adjusted net profit/(loss) attributable to ordinary shareholders (non-GAAP) and adjusted basic and diluted net profit/(loss) per share/ADS (non-GAAP), in evaluating its operating results and for financial and operational decision-making purposes. The Company defines adjusted cost of sales (non-GAAP), adjusted research and development expenses (non-GAAP), adjusted selling, general and administrative expenses (non-GAAP) and adjusted profit/(loss) from operations (non-GAAP) and adjusted net profit/(loss) (non-GAAP) as cost of sales, research and development expenses, selling, general and administrative expenses, profit/(loss) from operations and net profit/(loss) excluding share-based compensation expenses and organizational optimization charges. The Company defines adjusted net profit/(loss) attributable to ordinary shareholders (non-GAAP) and adjusted basic and diluted profit/(loss) per share/ADS (non-GAAP) as profit/(loss) attributable to ordinary shareholders and basic and diluted profit/(loss) per share/ADS excluding share-based compensation expenses, organizational optimization charges and accretion on redeemable non-controlling interests to redemption value. By excluding the impact of share-based compensation expenses, organizational optimization charges and accretion on redeemable non-controlling interests to redemption value, which are either non-cash or not indicative of the Company’s ordinary or ongoing operations due to their size or nature, 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 profit/(loss) or other consolidated statements of comprehensive profit/(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.
