HCV world-wide sales for 3Q16 and all of 2016:
--------3Q16---------------2016-------
GILD -3,325 77.9% - 11,605 - 79.6%
BMY - 379 - 8.88% - 1,352 - 9.27%
ABBV - 378 - 8.85% - 1,211 - 8.30%
MRK - 164 - 3.84% - 326 - 2.2%
JNJ - 21 - .49% - 79 - .54%
TOTAL - 4,267 -- 14,573
Since the 2015 total was 22,703, '16 sales will be down at least 17%. And '17 should be down another 10%+ without significant additional discounting.
Since BMY is disappearing in the US (its primary market) and ABBV continues to lose share to MRK in the US (not nearly as important since ABBV already has such a small share), MRK will be the main competition in the US until ABBV comes with its 2nd generation product.
The main issue continues to be how much market there will be in 2018 and beyond. GILD's OUS sales have decreased much more significantly than its US sales. Clearly the Japanese price decrease is a big part of that, but the EU decrease is more of a surprise. ABBV is clearly taking some market share there, but its overall OUS sales are not really growing either. It appears that EU sales industry wide are going to fall going forward also.
The market is pricing GILD (and ENTA) as though the fall will be steep and with stop. The market had underestimated the sales in '14 and '15 and overestimated the sales in '16. Whether it is right now is anyone's guess. FWIW, my guess is that '17 and '18 will be down years in the 20% range (assuming no real price war in generation 2 products), and that the decreases will be smaller thereafter. I still think that GILD will maintain a ~80% market share WW. BMY will not have much share and ABBV will have the rest with its 2G product. But with the much smaller overall market, ABBV sales will not be much (if any) above its sales for '15. Of course further trials could show a problem with side effects that charge the prospects for GILD and/or ABBV greatly.
As always, JMO.
