Vitamins Antitrust Litigation

Analysis Group has assisted a group of law firms representing large vitamin manufacturers in multiple federal and state litigations. The lawsuits have been brought by direct and indirect purchasers of vitamin products. In the direct purchaser litigations, we developed pricing models to compute “but-for” prices for bulk vitamin products. In the indirect purchaser litigations, we evaluated class certification and calculated damages to plaintiffs. We applied advanced econometric models to transactional and aggregate data to assess pass-through along complex supply chains. The Analysis Group team included Managing Principal Pierre Cremieux, and Vice Presidents George Kosicki, Tamar Sisitsky, Patrick Lefebvre, and Adam Decter, in support of several academic affiliates including Professor Robert Pindyck of MIT, who filed an expert report.
