Wells Fargo analyst David Maris believes the lawsuit by 44 states against 20 generic drugmakers will weigh on generic drug stocks this week and remain an "overhang issue for some time." Actual penalties and damages are impossible to calculate, but could be material, Maris tells investors in a research note. The analyst spoke to the Connecticut attorney general's office this morning and learned they are preparing for trial in these cases. Language the attorney general has used, such as "unprecedented" and his desire to clawback all gains from collusion, should be indicative of the states' intent, Maris writes. He believes that for a sector that is generally highly levered, and with some companies named already facing an overhang from opioid litigation like Teva (TEVA), this is "especially unwelcome news."
