Searching the Orange Book for Lupin does show 9 drugs classified as BX, while all of Laurus’ approvals remain as AB.
Jefferies’ claim that the list is incomplete could be true, as Lupin is now up to 9 rating changes, Amneal is up to 31. (Although it’s possible that some may already have had BX status and aren’t new changes, but I don’t track these companies)
If the information from this source is true, we should expect one rating change in a few days.
