A Twitter shareholder Wednesday filed a lawsuit against Elon Musk and Twitter, Inc. and alleged that Musk’s statements, tweets and conduct surrounding his possible purchase of the tech giant negatively affected Twitter’s stock. Since Musk announced his intention to purchase Twitter, the company has lost $8 billion in value.

Shareholder William Heresniak filed the proposed class action complaint “on behalf of all stockholders of Twitter, Inc. who have been harmed and/or are threatened with harm by Defendants’ unlawful conduct in connection with Musk’s proposed buyout of Twitter.”

Musk offered his Tesla stock as collateral for a $12.5 billion loan to purchase Twitter. Shortly after, financial institutions expressed concern over Tesla’s working conditions and recent series of electric vehicle fires. Telsa’s stock has now dropped more than 35% since the buyout announcement.

The complaint alleges that Musk found himself with “a unique and multi-billion-dollar” issue: if Tesla’s stock continues to fall, Musk may need to put up additional collateral for his loan. Therefore, Heresniak believes Musk intentionally engaged in “unlawful conduct” to tank Twitter’s value. Heresniak seeks a jury trial, declaratory and injunctive relief, punitive damages and attorneys’ fees.
