SpaceX has told employees that the stock option vesting date, when shares granted as stock options become eligible for sale, will be brought forward to April instead of May as originally expected, people familiar with the matter said.The accelerated vesting arrangement is expected to help ease employee concerns about the number of shares the company will be able to sell if it goes public.
The move is another sign that SpaceX is getting closer to filing public filings for an IPO. If the company achieves its fundraising goal of up to $75 billion, it would be the largest IPO ever. According to people familiar with the matter, SpaceX is expected to publicly submit IPO listing documents at the end of May and price the company in the week of June 15.
When a company goes public, it usually states in a prospectus filed with the Securities and Exchange Commission how many shares are available for sale on the first day of trading and the status of stock options that have been granted to employees.
People familiar with the matter said relevant discussions are still ongoing and IPO details such as the timing may change. Representatives for SpaceX did not immediately respond to a request for comment.
