Elon Musk will remain at Tesla under a 10-year, all-or-nothing pay package that demands massive growth.
The agreement, revealed today in a regulatory filing, requires that Tesla grow in US$50 billion ($67.9b) leaps, to a staggering US$650b market capitalisation.
To put those demands in perspective, the electric car maker, based in Palo Alto, California, is worth less than US$60 billion today.
Tesla must hit a series of escalating revenue and adjusted profit targets, only after which Musk would vest stock options worth 1 per cent of company shares. He would get no other guaranteed compensation including salary, bonuses or equity "that vests simply by the passage of time", Tesla said.
The pay still needs the approval of Tesla shareholders, who will vote on it at a special meeting in late March. Elon and Kimbal Musk, Elon's brother, will recuse themselves from the vote.
If the goals are reached, Tesla would be one of the biggest companies in America, and Musk's wealth would grow exponentially.
The US$650b benchmark would make Tesla the fourth-most valuable US company, behind only Apple, Alphabet, and Amazon.com based on current valuations. It would be larger than Microsoft, and would exceed the current combined valuation of the world's top eight publicly-traded auto companies.
Tesla's plan to meet those goals was laid out in 2016 in a document Musk called "Master Plan, Part Deux".
Tesla will expand from electric cars and SUVs to trucks — including a semi tractor-trailer that's due out in 2019 — and buses. It will continue to work on autonomous vehicle technology and plans to enter the car-sharing business, letting owners share their cars when they're not using them and running Tesla-owned fleets in cities.
The company, which bought solar panel maker SolarCity in 2016, also plans to expand its solar panel and energy storage businesses.
In order to vest shares when milestones are reached, Musk must stay on as CEO or serve as both executive chairman and chief product officer. That would give Tesla the option of hiring a different CEO in the future.
Tesla, which turns 15 this year, has never earned a full-year profit. It has reported only two profitable quarters since it went public in 2010.
Tesla said while it doesn't currently intend for Musk to step away from the CEO role, the terms allow Musk to potentially focus more of his attention on key product and strategic matters.
Musk is also the founder and CEO of rocket maker SpaceX and the co-founder and chairman of OpenAI, a nonprofit that researches artificial intelligence. He was also the founder of the online payment service PayPal.
