(Bloomberg) -- Elon Musk, already in hot water with securities regulators over his Twitter use, said in a tweet that Tesla Inc. would make more than 500,000 cars in the next 12 months.

The forecast, made as part of a seemingly innocuous aside in a discussion about the future value of Tesla vehicles, nonetheless comes as Musk’s lawyers are negotiating with U.S. Securities and Exchange Commission lawyers about whether the chief executive officer violated a settlement intended to put controls in place relating to his tweets. U.S. District Judge Alison Nathan has given the two sides an April 18 deadline to rework the language of their agreement so there won’t be any ambiguity on what Musk is allowed to post.

In an April 3 statement, Tesla reiterated its forecast for as many as 400,000 vehicle deliveries in calendar year 2019.
