StarKist agreed to plead guilty on Thursday to one felony charge of price fixing for its role in a broad conspiracy to rig the price of canned and ready-to-eat tuna, the Justice Department said.

The company faces a fine of up to $100 million for forcing shoppers to pay inflated prices from at least November 2011 through December 2013, the Justice Department said.

The amount is to be determined in a hearing by the United States District Court in San Francisco, which must also approve the terms of StarKist’s plea agreement. StarKist, an American subsidiary of Dongwon Industries of South Korea, has also agreed to cooperate with the federal investigation, which began in 2015.

“The conspiracy to fix prices on these household staples had direct effects on the pocketbooks of American consumers,” said Makan Delrahim, an assistant attorney general in the Justice Department’s antitrust division. “We will continue to hold companies and individuals who cheat consumers accountable.”
