Potential partners have been reluctant to move forward amid the heightened scrutiny, but a deal could still come together, the report said https://www.wsj.com/articles/nikolas-talks-with-major-energy-firms-stalled-following-short-seller-report-11600872115?mod=searchresults&page=1&pos=1 on Wednesday, citing people familiar with the matter.

Nikola and BP did not immediately respond to Reuters requests for comment.

The electric-truck maker's shares sank again on Wednesday, falling 26% to $21.15.

In a scathing report two weeks ago, short-seller Hindenburg Research said it had enough evidence to show Nikola and its founder Trevor Milton made false claims about the company's proprietary technology to form partnerships with automakers.

Following the allegations, Milton quit, but Nikola's Chief Financial Officer Kim Brady said on Tuesday the company has the backing of all its existing automotive partners.

Nikola has publicly rejected the accusations and has threatened to take legal action against Hindenburg.
