Ringler claimed that Twitter did not provide Musk with relevant business information he requested, as Ringler said the contract would require. Musk has previously said he wanted to assess Twitter’s claims that about 5% of its monetizable daily active users (mDAUs) are spam accounts.

“Twitter has failed or refused to provide this information,” Ringler claimed. “Sometimes Twitter has ignored Mr. Musk’s requests, sometimes it has rejected them for reasons that appear to be unjustified, and sometimes it has claimed to comply while giving Mr. Musk incomplete or unusable information.”

Ringler also charged in the letter that Twitter breached the merger agreement because it allegedly contains “materially inaccurate representations.” This accusation is based on Musk’s own preliminary review of spam accounts on Twitter’s platform. Twitter has said it’s not possible to calculate spam accounts from solely public information and that a team of experts conducts a review to reach the 5% figure.

“While this analysis remains ongoing, all indications suggest that several of Twitter’s public disclosures regarding its mDAUs are either false or materially misleading,” Ringer alleged.

He also claimed Twitter breached its obligations under the agreement to get Musk’s consent before changing its ordinary course of business, pointing to recent layoffs at the company.

Twitter did not immediately respond to a request for comment.
