 Delivered 3,318 ES8 vehicles in December 2018

 2018 cumulative deliveries of ES8 reached 11,348

SHANGHAI, China, Jan. 10, 2019 (GLOBE NEWSWIRE)  NIO Inc. (NIO or the Company) (NYSE: NIO), a pioneer in Chinas premium electric vehicle market, today provided its December 2018 delivery results.

As of December 31, 2018, aggregate deliveries of the Companys ES8, its 7-seater, high- performance premium electric SUV, reached 11,348 vehicles, 3,318 of which were delivered in December.

With 11,348 ES8 deliveries in 2018, we exceeded our delivery goal for our first calendar year as a public company, said William Li, founder, chairman and chief executive officer of NIO. 2018 has been a milestone year for us, as we produced and delivered over 11,000 ES8s and launched our second production car, the ES6, a 5-seater high-performance premium electric SUV on NIO Day in December 2018. We will continue to focus on market penetration by delivering high-quality products and holistic services to our users and to improve the system efficiency of our development and operations.

We are pleased with the solid ramp-up in production and delivery in 2018, which demonstrated our execution capabilities, added Louis T. Hsieh, NIOs chief financial officer. The delivery of 3,318 ES8s in December exceeded our expectation, which was in part due to accelerated deliveries made at the year end in anticipation of expected EV subsidy reductions in China in 2019. Despite an overall challenging automotive market and the seasonal low demand in the first quarter, we remain committed to expanding our sales network and strengthening our brand to support our future growth.
