Binary regulatory risk - FDA rejection or clinical trial failure of aficamten would eliminate 70-80% of current valuation given pipeline concentration
Reimbursement pressure from payers challenging specialty drug pricing, particularly for cardiovascular indications without mortality benefit data
Manufacturing scale-up risk transitioning from clinical to commercial production without established infrastructure
Patent cliff exposure with key composition-of-matter patents expiring 2030s, limiting commercial exclusivity window
Bristol Myers Squibb's mavacamten (Camzyos) already approved for obstructive HCM with 2+ year head start and established market presence
Multiple cardiac myosin inhibitors in development (BMS next-gen compounds, other competitors) targeting same patient population
Established heart failure therapies (SGLT2 inhibitors, ARNIs) expanding indications into Cytokinetics' target markets
Risk of superior efficacy/safety profiles from competitor programs rendering pipeline assets non-competitive
Cash burn of $400M annually provides approximately 2.5-3 year runway, requiring additional capital raises that dilute existing shareholders
Negative operating cash flow and no revenue generation creates dependence on capital markets access during potential downturns
