Tesla  CEO Elon Musk said deliveries for the company’s long-awaited trucking models would begin as early as this year and into 2023.

Deliveries for Tesla’s (ticker: TSLA ) 500-mile range semi-truck will start this year, Musk said in a tweet, five years after its official unveiling.

The CEO previously had indicated that the model would arrive on roads in 2023, along with the Cybertruck, Tesla’s pickup truck. The Cybertruck’s projected shipping date is still next year, Musk said on Wednesday.

Tesla unveiled the Cybertruck in 2019, but production has faced multiple delays over the course of the last three years. That’s slated to pick up now that the company has inaugurated its new manufacturing facility in Austin, Texas,, where the Cybertruck will be produced.

The production delays have weighed heavily on Tesla stock, causing the share price to fluctuate. But investors reacted positively to Musk’s update, with the stock up 1.6% to $861.68 on Wednesday.

Musk also made waves Tuesday night by disclosing he had sold $6.9 billion of Tesla stock over three days in more than 120 separate transactions. In April, he sold shares worth about $8.5 billion, presumably to fund his acquisition of social media platform Twitter ( TWTR ). He still holds about 155 million shares of Tesla.
