Papa John’s founder John Schnatter on Monday demanded that the pizza chain remove a provision that bars him from talking to other investors about the company — a policy he says will lead to a “significant loss” for shareholders.

Papa John’s board adopted a “poison pill” in July to thwart takeover attempts days after Schnatter, who holds 31 percent of Papa John’s shares, stepped down as chairman after a series of racially tinged controversies.

Also included in the poison pill was a so-called “wolf pack” provision, which prevents Schattner from speaking to current and potential investors about the company.

In a fiery letter to Papa John’s board released in a Monday regulatory filing, Schnatter claims that the “wolf pack” provision violates law in Delaware, where the pizza chain is incorporated, and is an “infringement on shareholders’ rights.”

He noted that “several third parties” have tried to speak with him about Papa John’s, but the provision blocks those conversations.

It is not known if those third parties are interested in teaming up with Schnatter to buy the company, or want to pursue other plans for Papa John’s.

Earlier this month it was reported that billionaire Nelson Peltz’s Trian Fund requested information on Papa John’s as it explored a possible bid. Peltz reportedly met with Papa John’s in June, when Schnatter was still chairman, and brought along Wendy’s Chief Executive Todd Penegor.

Both Trian and Papa John’s declined to comment on the hedge fund’s reported interest at the time, with each noting that it doesn’t comment on “market rumors.”

Schnatter also took a swipe on Monday at Chief Executive Steve Ritchie, who assumed the top spot in January after Schnatter criticized NFL leadership for its handling of the national anthem protests.

“The leadership team that Steve Ritchie established is crumbling, and now he is promoting the wrong people and losing long-term employees who provided the essence of what Papa John’s was created to do — provide customers with better ingredients and better pizza,” Schnatter wrote.

Although Schnatter remains a board member, he was barred from the corporate office in July after it was revealed that he used the N-word on a marketing call in May.

Reps from Papa John’s defended the poison pill provision Monday, saying it was in the “best interests” of shareholders.

“The plan also reduces the likelihood that any person or group gains control of Papa John’s without paying an appropriate control premium to all of the company’s stockholders,” the company added.

Reps for Schnatter declined to comment beyond Monday’s filing.
