ORDER DENYING TRANSFER
SARAH S. VANCE, ChairBefore the Panel:* The Express Scripts defendants1 move under 28 U.S.C. § 1407 to centralize this litigation in the Eastern District of Missouri. This litigation currently consists of four actions pending in two districts, as listed on Schedule A. Plaintiffs in all actions and defendant Anthem, Inc. (Anthem) oppose centralization. In the alternative, plaintiffs in the Southern District of New York actions and Anthem request that district.
On the basis of the papers filed and the hearing session held, we conclude that centralization is not necessary for the convenience of the parties and witnesses or to further the just and efficient conduct of the litigation. The actions unquestionably share common factual allegations concerning ESI’s provision of pharmacy benefit-management services- for- Anthem health plans and, in particular, ESI’s alleged failure to provide competitive pricing for prescription drugs. But where only a minimal number of actions are involved, the proponent of centralization bears a heavier burden to demonstrate that centralization is appropriate. See In re: Transocean Ltd. Sec. Litig. (No. II), 753 F.Supp.2d 1373, 1374 (J.P.M.L. 2010). *1371Moving defendants have failed to do so here.
There are only four actions in this litigation, and three actions already are proceeding as related cases before the same judge in the Southern District of New York.2-The Express Scripts defendants, are represented principally by two counsel in the underlying actions, who are well-positioned to coordinate the litigation across the four actions. All responding parties except for movants agree that informal coordination of discovery and pretrial proceedings is practicable and preferable to centralization.
Additionally, the ERISA action raises ease-specific factual and legal issues concerning the extent of overpayments allegedly made by Anthem plan participants, ESI’s and Anthem’s duties under ERISA, and putative classes not implicated in any other action. These case-specific issues are likely to undermine the alleged efficiencies that could be gained from centralizing an already minimal number of actions. '
Although movants believe that the filing of related actions is likely, the mere possibility of additional'actions does not support centralization. See, e.g., In re: California Wine Inorganic Arsenic Levels Prods. Liab. Litig., 109 F.Supp.3d 1362, 1363 (J.P.M.L. 2015).
Given the limited number of involved counsel and actions, and the presence of significant non-overlapping issues in one action, informal coordination of discovery and pretrial motions is preferable to centralization. See, e.g., In re: United Healthcare Servs., Inc., Harvoni (Ledipasvir and Sofosbuvir) Health Ins. Litig., 222 F.Supp,3d 1339 (J.P.M.L. 2016); see also Manual for. ■ Complex Litigation, Fourth, § 20.14 (2004).
IT IS THEREFORE ORDERED that the motion for centralization, of these actions is denied.
