Tesla Inc. countersued JPMorgan Chase on 24 January, intensifying a dispute over the payout for a bond sale the bank helped arrange in 2014.

JPMorgan started the fight with a lawsuit in November, claiming it was owed around $162m more for a set of warrants it had acquired as part of the bond sale. Tesla on 24 Monday said the bank wasn’t entitled to the billions of dollars in stock it got last year from those warrants.
