[Discussion] How do PBMs in US rank drug companies on the formulary?

I understand the PBMs make deals with pharma companies and receive rebates in exchange for reduced prices and listing the particular drug on Tier-1 of the formulary. But what happens when different companies compete for a similar drug (manufactured by both of them) to be listed in Tier-1? Whom does the PBM list? And what role does the US Govt. have in this?
