BUSINESS COMBINATION HEARTWARE, HVAD and the HEARTWARE logo are registered trademarks of HeartWare. Safe HeartWare®

HeartWare + Valtech: Creating the Technology Leader in Heart Failure MVAD® System will lead a transformation of MCS portfolio and VAD market, picking up where HVAD® leaves off Synergies with disease, customer, referral channel and delivery system will create compounding benefits over next decade Adjustable repair of MR and TR expected to emerge as firstline option, whether surgical or interventional Nearer-term commercial opportunity in established surgical and interventional mitral repair market with >$450M in sales Sophisticated CardioValve™ design and delivery system to enable HeartWare leadership in mitral replacement Combined pipeline creates unique opportunity for differentiated value creation HEARTWARE, HVAD and the HEARTWARE logo are registered trademarks of HeartWare.

Our Mitral and Tricuspid Market Investment Thesis Consistent With Valtech’s Portfolio Approach Repair’s Value Understood From Surgery • Surgical mitral repair long understood to be the preferred approach • Annuloplasty the most frequently performed surgical mitral repair Mitral Anatomy Complex • Multiple tools required to serve the spectrum of MR patients • A leading player in the mitral market needs repair and replacement Physicians Will Prefer to Repair First • Transcatheter mitral valve replacement (TMVR) will be much more challenging than TAVR • Repair will be a safer treatment and therefore the cardiologist’s first choice, when possible Transseptal Required to Meet TMVR Potential • The majority of inoperable mitral and tricuspid regurgitation patients are sick heart failure patients; left ventricular trauma a watch-out • Transseptal delivery necessary to achieve large market opportunity Tricuspid Next Horizon • Tricuspid regurgitation is drastically undertreated today, and there is a growing body of evidence supporting intervention • Tricuspid is a repair story; annuloplasty is preferred surgical approach HEARTWARE, HVAD and the HEARTWARE logo are registered trademarks of HeartWare.

Replacement Will Eventually Have Strong Place in the Market; Repair Represents Much Stronger Near- and Mid-Term Opportunity as Valve Technology Matures Repair Transapical Replacement Transseptal Replacement Phase I: Repair + Early TA Replacement Phase II: Repair + Mature TA and Early TS Replacement Phase III: Repair + Mature TS Replacement Repair • Repair safer, available first and more proven • Broader use in earlier disease stages and lower-risk patients • Mature repair market • Younger FMR patients • Growth in DMR Segment Replacement • Early transapical replacement outcomes varied • Mostly reserved for high-risk severe FMR patients • Mature transapical, early transseptal replacement • Mature transseptal replacement valves • Older FMR patients • Select DMR etiologies Note: Transapical (TA), Transseptal (TS).
