shouldn't take much for NVS to get $100M in profits from lovenox, assuming they maintain 35%-50% of the market
The assumption is too generous.
In some post I described a market channel segmentation* view of how sales might shake out. It would not be favorable to MNTA IF I have that right. That too suggests your numbers are too high.
But worst of all, how can anyone take the 45% profit share seriously once you know that the hybrid split was triggered by the AG AND we can reasonably expect an Amphastar launch (or a TEVA launch) which would reduce the payments to a straight royalty.
It is astonishing what foolish things one can temporarily believe if one thinks too long alone ... where it is often impossible to bring one's ideas to a conclusive test either formal or experimental. J.M. Keynes
