In mid—March this year, Levandowski agreed to plead guilty to one count of stealing materials from Google to make other criminal charges go away. He apologized to his former colleagues in a statement:

“The last three and a half years have forced me to come to terms with what I did. I want to take this time to apologize to my colleagues at Google for betraying their trust, and to my entire family for the price they have paid and will continue to pay for my actions.”

Meanwhile, Waymo told TechCrunch in a statement that Levandowki’s actions “erases the contributions of many” and that Alsup’s decision “represents a win for trade secret laws that promote cutting-edge technology development.” The rest of the statement reads:

“Anthony Levandowski’s theft of autonomous technology trade secrets has been enormously disruptive and harmful to Waymo, constituted a betrayal, and the effects would likely have been even more severe had it gone undetected.”

Although the former Google employee apologized to his colleagues, TechCrunch learned that he recently filed a lawsuit against Waymo and Uber that could make him a very rich man. He claimed that when the companies settled, one of the terms they agreed upon was that he could never work for Uber again. As a result, the ride-hailing giant reneged on its promises when it acquired Otto, his self-driving truck startup.

Apparently, one of things Uber promised him was an earnout plan that would give him “a percent interest of billions in profit for Uber’s new trucking business.” Further, the lawsuit claims that he may not have been the only Google employee to steal trade secrets from the company. Levandowski is now asking for at least $4.128 billion, which he believes he would’ve earned from the earnouts he was promised.

After about three years of legal wrangling between Uber and Waymo over self-driving car tech, the engineer at the center of it has agreed to plead guilty to one count of stealing materials from Google. Anthony Levandowski was a lead engineer on the self-driving car project that’s now known as Waymo, until he left to form his own company, Otto, which Uber then acquired.

Reuters reports that the agreement will see all the other criminal charges go away while he admits to taking a file that tracked Google’s goals for its self-driving car project. A court already ruled that Levandowski owes Google $179 million for violating his contract, and he has declared bankruptcy. Prosecutors said they will recommend a sentence of fewer than 30 months.

Levandowski’s new company was later acquired by Uber, igniting a court battle between the two corporations. Google accused the ride-hailing titan of colluding with its former employee to steal secrets from Waymo before he left. This particular case, however, only addresses Google’s contract dispute complaint.

Back in December, an arbitration panel ruled that Levandowski and colleague Lior Ron breached their legal obligations, as well as engaged in unfair competition, when they started a rival company and brought Google employees over. Ron chose to settle with Google, but Levandowski decided to dispute the ruling. Now, a San Francisco County court has denied his petition and backed the panel’s decision.

That said, it’s unclear if he has to pay anything. Uber may have to shoulder the payment, depending on the terms of his contract. In addition, Levandowski has filed for bankruptcy to be able to negotiate debts, telling the court he only has $50 million to $100 million in estimated assets, which aren’t enough to pay off between $100 million and $500 million in liabilities.
