The investigation focuses on whether Express Scripts and certain of its officers and/or directors violated federal securities laws. On April 24, 2017, the Company announced that it is losing its biggest customer, Anthem Inc., who claims that Express Scripts overcharged it by billions of dollars and so will not renew its contract with the Company when it expires in 2019.
