Simplify's Take

What believers are saying

  • Q2 2026 revenues reached $628.7 million, with CABOMETYX U.S. sales up 10%.
  • Exelixis repurchased $311.6 million in Q2 2026 and extended authorization through 2027.
  • Zanzalintinib’s STELLAR-303 data support a December 2026 FDA decision and launch preparations.

What critics are saying

  • CABOMETYX concentration leaves Exelixis exposed if renal and NET demand slows again.
  • FDA review ends December 3, 2026; a narrow zanzalintinib label crushes launch economics.
  • Teva can launch CABOMETYX generics January 1, 2031, threatening the cash engine.

What makes Exelixis unique

  • CABOMETYX remains a multi-indication oncology franchise with durable U.S. demand in 2026.
  • Exelixis paired disciplined buybacks with pipeline expansion, retiring 93.3 million shares since 2023.
  • Zanzalintinib targets colorectal cancer first, then six additional pivotal programs across tumor types.

Exelixis retires 8% of shares with $1.1B buyback as zanzalintinib awaits December FDA decision

Exelixis has spent approximately $1.1 billion buying back its own shares over the past year, reducing shares outstanding by 8.0%. This mechanical effect means existing shareholders now hold larger stakes in the business without taking any action. The company's CABOMETYX oncology drug generated $573 million in US net product revenue in the second quarter of 2026, up roughly 10% year-on-year. Exelixis converts 47.5% of revenue into free cash flow, which funds the buyback programme. The company has revised its 2026 total revenue guidance downward to $2.50 billion to $2.55 billion, lowering the midpoint by $50 million. Management attributed this to a slower ramp for the neuroendocrine tumour indication. The stock trades at 15.8 times trailing earnings. The company's next growth driver, zanzalintinib, awaits a regulatory decision for colorectal cancer in early December 2026.

Why this top-ranked IBD 50 stock just plummeted on its earnings. * ALLISON GATLIN * Updated 05:08 PM ET 08/05/2026 IBD 50 stock Exelixis (EXEL) toppled late Wednesday on a mixed second-quarter report, as sales of its bread-and-butter cancer drug, cabozantinib, lagged expectations. The biotech company sells cabozantinib under the brand names Cabometyx and Cometriq. The former - a treatment for kidney, liver and thyroid cancers as well as neuroendocrine tumors - brought in $570.6 million in quarterly sales. Cometriq, which treats a form of thyroid cancer, generated $2.4 million in sales. But analysts called for a healthier $578 million and $3 million in sales, respectively. Biotech's Next Boom?

More promisingly, Exelixis topped earnings forecasts, reporting an adjusted 91 cents per share, vs. the Street's forecast for 85 cents, according to FactSet. Earnings grew more than 21% as total sales climbed close to 11%, reaching $627.8 million. That includes sales of Cabometyx and Cometriq, as well as $53.2 million in royalties from partners Ipsen and Takeda Pharmaceutical. But sales lagged projections for $636 million. Investors are now watching closely the next steps for zanzalintinib. The Food and Drug Administration is reviewing the experimental prostate cancer treatment for potential approval in December.
