Thesis Summary

Exelixis combines a growing and profitable cabozantinib franchise with a potentially transformative but binary near-term regulatory catalyst for zanzalintinib. Second-quarter 2026 U.S. cabozantinib-franchise net product revenue reached $573.0 million, while management maintained substantial full-year revenue expectations after narrowing them. Zanzalintinib's NDA is under FDA review with a December 3, 2026 action date, supported by statistically significant overall-survival improvement in the STELLAR-303 intention-to-treat population. However, the non-liver-metastases subgroup did not achieve statistical significance, and STELLAR-304 remains an important unreported phase 3 test.

Bear CaseDownside scenario
$41.0023%

The FDA delays or rejects the zanzalintinib application, imposes a commercially restrictive label, or STELLAR-304 misses at least one primary endpoint. Concurrently, cabozantinib net product revenue falls below the revised guidance floor, increasing dependence on an aging flagship franchise and reducing confidence in the timing of a second growth platform.

Base CaseCentral scenario
$52.9457%
Matches the consensus mean

CABOMETYX continues to generate substantial revenue within the revised 2026 guidance range while investors await the December 2026 FDA decision and second-half STELLAR-304 data. Zanzalintinib retains meaningful strategic value, but the missed statistical threshold in the STELLAR-303 non-liver-metastases subgroup and normal regulatory uncertainty constrain conviction.

Bull CaseUpside scenario
$66.0020%

The FDA approves zanzalintinib plus atezolizumab by the assigned action date without a materially restrictive label, establishing Exelixis's second commercial franchise. CABOMETYX remains within or above revised 2026 guidance, and STELLAR-304 reports favorable primary-endpoint results, supporting expansion of zanzalintinib beyond colorectal cancer.

Scenarios are anchored to street consensus at the research date, with our probabilities and rationale.

Key Investment Merits
  • Second-quarter 2026 U.S. cabozantinib-franchise net product revenue increased to $573.0 million from $520.0 million in the comparable 2025 quarter, primarily from higher sales volume.
  • The FDA accepted the zanzalintinib-plus-atezolizumab NDA and assigned a December 3, 2026 target action date, creating a defined potential second-franchise catalyst.
  • STELLAR-303 achieved statistically significant overall-survival improvement in its intention-to-treat population, providing the principal efficacy basis for the pending application.
  • The zanzalintinib program spans multiple pivotal and expansion studies, including STELLAR-304, STELLAR-311, STELLAR-316, LITESPARK-033, and LITESPARK-034.

Key Investment Risks
  • The STELLAR-303 non-liver-metastases subgroup showed only a non-statistically-significant overall-survival trend, creating regulatory and labeling uncertainty.
  • Exelixis reduced its 2026 total-revenue and net-product-revenue guidance ranges from the ranges initially issued in January 2026.
  • The near-term diversification thesis depends heavily on FDA approval and successful commercialization of zanzalintinib in metastatic colorectal cancer.
  • STELLAR-304 topline results remained pending as of the latest company update, leaving material clinical risk in a potential renal-cell-carcinoma expansion.
