Alex Denner

Alex Denner developed his healthcare activism expertise while working at Icahn Capital as a portfolio manager focused on pharmaceutical companies. In 2012, he founded Sarissa Capital Management to apply activist strategies specifically to healthcare. Sarissa's approach involves identifying pharmaceutical or biotech companies with strong underlying assets but poor management execution, then working to unlock value through strategic alternatives including sales, spin-offs, or management changes. Notable campaigns include Allergan (before its takeover), Biogen, Ariad Pharmaceuticals, Medivation, and ImClone. Denner holds a PhD in biochemistry from Harvard, giving him genuine scientific expertise to evaluate pipeline value — a critical differentiator in healthcare activism where understanding drug efficacy is essential to the investment thesis.
