Business Economics — Johnson & Johnson
Ticker: JNJ | Currency: USD | Most recent data: FY2025 (fiscal year ended Dec 28, 2025)
J&J is a two-segment healthcare company that makes money by (1) selling patent-protected pharmaceuticals and biologics (Innovative Medicine, ~63% of revenue) and (2) selling medical devices, surgical instruments, and contact lenses (MedTech, ~37%). The Consumer Health business (Kenvue) was separated in 2023. J&J has further announced a planned separation of its Orthopaedics business, continuing a portfolio simplification strategy.
The economic engine is strengthening — but unevenly. Innovative Medicine is the real profit driver, with operating margins above 40%, powered by blockbuster franchises in oncology (DARZALEX, ERLEADA, CARVYKTI), immunology (TREMFYA, successor to STELARA), and neuroscience (SPRAVATO). FY2025 consolidated sales were approximately $91.7B, up ~5–6% operationally from FY2024's $88.8B. The Innovative Medicine segment grew faster than MedTech, which is structurally a mid-single-digit grower tied to procedure volumes.
The critical question is the STELARA patent cliff. STELARA (~$10B+ at peak) began facing biosimilar competition in early 2025 in the U.S. and Europe. J&J has been preparing for years — TREMFYA's expanded indications, DARZALEX's continued penetration into earlier lines of therapy, and CARVYKTI's CAR-T ramp are all designed to fill this gap. Management has guided that new product launches from its pipeline should more than offset STELARA erosion by 2026–2027. Whether this plays out on schedule is the single biggest near-term variable.
This is a genuine win-win model. J&J's drugs treat serious diseases (cancer, autoimmune disorders) with measurable clinical benefit — the products earn their pricing through demonstrated efficacy in randomized trials. MedTech sells instruments that enable surgeries. Neither segment relies on extracting rents from captive customers.
No structural deterioration. Revenue is growing across both segments. The pipeline has 100+ programs. The concern is cyclical — patent cliffs are a recurring feature of pharma, not a sign of business decay. J&J has navigated them before (Remicade, Procrit).
Key governing metrics: (1) Innovative Medicine organic growth ex-STELARA — measures whether the pipeline is working; (2) MedTech procedure volume growth — proxy for underlying demand; (3) Adjusted operating margin — tracks pricing power vs. cost inflation; (4) R&D yield — new molecular entity approvals per dollar spent; (5) Free cash flow conversion — J&J typically converts >90% of net income to FCF, funding its 62-year dividend increase streak.
