Shares of Nio (NYSE: NIO ) stock are in the red today following a concerning report about Tesla’s (NASDAQ: TSLA ) Chinese production. According to Bloomberg ,
Tesla notified employees at its Shanghai Gigafactory to work five days a week instead of the normal 6.5 days. The plant produces the
Model 3 and Y. Meanwhile, the plant’s schedule of two 11.5-hour shifts per day remained unchanged. Production lines, such as battery workshops, could see limitations for an extended period of time. These production limits are expected to last through April, according to people familiar with the situation. This fares poorly for Nio, which has already seen its shares decline by over 40% year-to-date. At the same time, Nio’s fourth-quarter earnings showed improvements on several metrics, although the company remains unprofitable with slowing revenue growth. For the quarter, vehicle revenue grew by 4.6% year-over-year to $2.17 billion. Deliveries grew by 25% to 50,045, while vehicle margins increased to 11.9% from 6.8%. Net loss was $756 million compared to $800 a year ago.
