I found it linked in some articles, e.g. here in the first paragraph: https://alabamareflector.com/2023/12/13/lawsuit-alleges-alabama-prisons-using-forced-labor/

Skimming through it, I see these companies named as defendants:

franchisees of McDonald’s, KFC, Wendy’s, and Burger King; Bama Budweiser, a distributor of Anheuser-Busch products; poultry and meat processors including Gemstone Foods, Koch Foods, and Southeastern Meats; Paramount Services, a linen company; and manufacturing and engineering employers Masonite, Cast Products, Ju-Young, Hwaseung, SL Alabama, and Progressive Finishes.
