Why Is Jazz (JAZZ) Down 6.9% Since Last Earnings Report?
Jazz Pharmaceuticals missed Q2 2026 EPS expectations ($5.71 vs. $6.04 estimate) due to $77 million in acquired IPR&D expenses, but beat revenue estimates at $1.21 billion. The company raised full-year 2026 revenue guidance to $4.60-$4.75 billion, driven by strong performance in its sleep franchise (Xywav up 13%), epilepsy business (Epidiolex up 16%), and oncology portfolio (up 32%). Despite the positive outlook, shares have underperformed the S&P 500 by 6.9% since the earnings report.
