Thesis Summary

Amgen entered the second half of 2026 with strong portfolio momentum: its six key growth drivers expanded 26% year over year and represented nearly 70% of second-quarter product sales. Repatha, EVENITY, UPLIZNA, TEZSPIRE, BLINCYTO and IMDELLTRA delivered substantial growth, while MariTide advanced through a broad Phase 3 program. The counterweight is accelerating biosimilar and pricing pressure on Prolia, XGEVA, Otezla and Enbrel, alongside unresolved TAVNEOS regulatory proceedings and partial clinical holds affecting subcutaneous blinatumomab studies.

Bear CaseDownside scenario
$230.0018%

The bear case assumes biosimilar and government-pricing pressure accelerates across Prolia, XGEVA, Otezla and Enbrel before newer products can fully replace lost sales. It also incorporates a material MariTide Phase 3 setback, an adverse TAVNEOS withdrawal outcome, or prolonged clinical holds affecting subcutaneous blinatumomab, any of which would weaken confidence in pipeline replacement capacity.

Base CaseCentral scenario
$383.6658%
Matches the consensus mean

The base case assumes continued expansion of Repatha, EVENITY, TEZSPIRE, UPLIZNA, BLINCYTO and IMDELLTRA broadly offsets declining denosumab, Otezla and other mature-product sales. MariTide remains a promising but unapproved late-stage asset, while TAVNEOS and subcutaneous blinatumomab regulatory issues remain manageable.

Bull CaseUpside scenario
$452.0024%

The bull case assumes Amgen's key growth medicines sustain strong volume-led adoption, MariTide's extensive Phase 3 program progresses without a pivotal failure, and newer assets such as IMDELLTRA, UPLIZNA and PAVBLU more than offset erosion in mature products. MariTide's differentiated monthly-to-quarterly dosing potential and broad obesity-related outcomes program could materially expand Amgen's long-duration growth profile.

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

Key Investment Merits
  • The six key growth drivers grew 26% year over year and generated nearly 70% of second-quarter 2026 product sales, indicating that growth is increasingly supported by newer medicines.
  • MariTide has a broad Phase 3 program spanning chronic weight management, cardiovascular outcomes, heart failure, obstructive sleep apnea, treatment switching and long-term maintenance.
  • Multiple products delivered strong second-quarter growth, including Repatha at 37%, EVENITY at 38%, UPLIZNA at 90%, TEZSPIRE at 42%, BLINCYTO at 23% and IMDELLTRA at 115%.

Key Investment Risks
  • Second-quarter 2026 sales declined 32% for Prolia and 34% for XGEVA as multiple biosimilars launched globally, creating material replacement pressure.
  • Otezla sales declined 21%, while Enbrel faced lower net selling prices associated with Medicare price setting and increased 340B mix.
  • The FDA-related TAVNEOS proceeding and partial clinical holds on subcutaneous blinatumomab studies create regulatory uncertainty independent of commercial execution.
