JPMorgan Chase & Co has sued Tesla and its founder, Elon Musk, for $162.2 million for “flagrantly” breaching a contract signed by the companies in 2014. The contract relates to warrants the automaker sold to the bank that year.

A warrant gives the holder the right to buy a stock at a set “strike” price and date. The suit revolves around the way that JPMorgan repriced its Tesla warrants in 2018, reports Reuters. The bank claims the warrants contained standard provisions that allowed it to adjust the price to protect itself against the economic effects of “significant corporate transactions involving Tesla.”

The bank argues that this scenario transpired in 2018 when it repriced the warrants after Musk tweeted on August 7, 2018, that he might take Tesla private at $420 per share and had “funding secured. The bank then changed the price again 17 days later, when Musk said that he was abandoning the plan.

JPMorgan Chase claims in a filing that it adjusted the strike price both times to “maintain the same fair market value” as before the tweets were published.

In 2019, Tesla called the adjustments “an opportunistic attempt to take advantage of changes in volatility in Tesla’s stock.” According to JPMorgan Chase, though, the automaker did not challenge the calculations that informed its changes.

“Though JPMorgan’s adjustments were appropriate and contractually required,” the bank said in the complaint, “Tesla has flagrantly ignored its clear contractual obligation to pay JPMorgan in full.”

The warrants expired in June and July, when the stock was in the midst of a tremendous upswing, which JPMorgan Chase says requires Tesla to hand over shares of its stock or cash under the contract. It argues that the automaker’s failure to do that amounted to a default.

Along with this lawsuit, the 2018 tweets referenced above led to an SEC investigation and brought civil charges and fines of $20 million against both Elon Musk and Tesla.
