United States v. Archer Daniels Midland Co. was a criminal case filed on October 15, 1996 in which the United States alleged that Archer Daniels Midland Company (ADM) and other corporations and individuals engaged in a conspiracy to fix and maintain prices of lysine and citric acid and to restrain or eliminate competing suppliers of these additives in violation of Section 1 of the Sherman Antitrust Act (15 U.S.C. § 1). ADM entered into a plea agreement in which ADM plead guilty to both antitrust counts and agreed to pay a combined fine of $100 million ($70 million for the lysine count and $30 million for the citric acid count). This is equivalent to $169.30 million in present-day terms and was at the time the largest antitrust fine ever imposed.
