Shares of embattled electric truck start-up Nikola (NKLA -1.06%) were trading lower on Friday, after steel company Worthington Industries (WOR 5.24%) revealed in a regulatory filing that it had sold its entire stake in the company.
As of 1 p.m. EST, Nikola shares were down about 6.2% from Thursday's closing price.
In an 8-K filing released after the market closed on Thursday, Worthington said that its subsidiary WI Ventures had sold its entire remaining stake in Nikola, just over 7 million shares, for about $147 million.
Worthington was an early investor in Nikola, providing the start-up with some of its initial funding back in 2015. This transaction was the third sale of its Nikola stock; in total, it realized over $600 million, selling at an average of about $34 per share.
To be clear, it's not the sale itself that drove Nikola's price down on Friday -- Worthington actually sold its stake on Wednesday -- but the news that yet another company connected with Nikola had effectively severed ties.
Nikola still has a connection to Worthington: Its CEO, Mark Russell, was formerly president and chief operating officer of the steel maker. But clearly the managers of WI Ventures didn't think the company's prospects warranted holding its stake any longer, despite Russell's leadership.
Auto investors hoping for an update from Russell can look ahead to Nikola's fourth-quarter earnings report, likely in mid-February.
