While New Year’s Eve is a time for celebration, Elon Musk seems to have other plans for the holiday. The Tesla (TSLA) CEO said he will ring in 2020, making sure the company meets its delivery deadline.

Musk posted a tweet on Monday confirming the news, saying he will be at Tesla’s Fremont, California, factory on New Year’s Eve when asked by one Twitter user what his plans are for the holiday were.

In his tweet, Musk said, he is going “to help with vehicle deliveries” as Tesla’s Q4 ends and the electric car company looks to get those last vehicles out the door in time to meet the quarter’s performance report.

In Q3 2019, Tesla fell short of analyst expectations for vehicle deliveries with 97,000 units that quarter, which was a record for the company. For Q4, Musk has said that Tesla will again break a record for vehicle deliveries as the company looks to meet its year-end goal of 360,000 and 400,000 units, CNBC reported.

There was no word from Musk if he will be working the entire eve to help with deliveries, or just stopping in to make sure everything is running smoothly. But Musk has reportedly been known to pull some late-night hours working, especially when there is a deadline to meet, Business Insider reported.

In the past, Musk has claimed to work 120 hours a week, the news outlet said. But this is not the first time that Musk has spent a holiday working as he also spent his 48th birthday on “global logistics,” when asked by a Twitter user how he would celebrate the day.

Shares of Tesla stock were up 1.12% as of 12:55 p.m. EST on Tuesday.
