Background on the Tyson Foods Securities Class Litigation

Tyson Foods, a Delaware Corporation with principal executive offices in Arkansas, operates together with its subsidiaries as a food company worldwide.

The action alleges that throughout the Class Period, defendants made materially false and/or misleading statements, and/or failed to disclose that: (i) Tyson Foods systematically colluded with several of its industry peers to fix prices in the broiler-chicken market; (ii) the foregoing conduct constituted a violation of federal antitrust laws; (iii) consequently, Tyson Foods’ Chicken segment revenues during the Class Period were the result of illegal conduct; and (iv) Tyson Foods lacked effective internal control over financial reporting.

On September 2, 2016, food distributor Maplevale Farms, Inc. (“Maplevale”) filed an antitrust class action complaint against Tyson Foods and several other poultry producers, alleging that the companies had conspired since 2008 to manipulate the prices of broiler chickens by coordinating and limiting production and exchanging detailed information about prices, capacity, and sales volume, in violation of the Sherman Antitrust Act.

On October 7, 2016, Pivotal Research (“Pivotal”) downgraded Tyson Foods from Hold to Sell based on Maplevale’s allegations that Tyson Foods and its industry peers engaged in price manipulation. On this news, Tyson Foods’s common stock price fell $6.63 per share, or 8.91%, from a closing price of $74.38 on October 6, 2016, to close at $67.75 per share on October 7, 2016, on extremely heavy trading volume.
