Mills commented, “We are not surprised by the MDT/HTWR deal this morning, although we are frankly underwhelmed by the price. To explain, despite recent challenges in HTWR’s VAD business – namely MVAD snafus and uncertainty regarding HVAD’s competitiveness with HeartMate 3 (STJ) until we see contemporary Stroke results from the ENDURANCE 2 trial) – we have remained bullish on HTWR, largely due to our belief in the long-term growth potential of the VAD market, and our belief that HTWR would turn the business around (partially predicated on our belief that E2 Stroke results would be positive and MVAD was not dead). In fact, we think in this, latter scenario – i.e. E2 Stroke rates below 15% (i.e. .15 events per patient year) and a narrative regarding MVAD that portended a return to human clinicals before year-end 2017 – could have driven the stock north of $60, even before an acquisition occurred. This is the reason we are underwhelmed by this deal.”
