The August 2023 Kenvue separation removed approximately $15 billion of consumer healthcare revenue from J&J's top line, along with the associated consumer brand portfolio (Tylenol, Band-Aid, Listerine). The strategic logic was clean: consumer health was growing slower than the rest of J&J, operated at lower margins, and was consuming management attention disproportionate to its profit contribution.
The remaining business has two segments. Innovative Medicine (pharma) represents approximately 60% of revenue and includes Darzalex, Stelara, Tremfya, Erleada, and the rapidly growing oncology pipeline (multiple myeloma, lung cancer, bladder cancer). MedTech represents approximately 40% of revenue and spans medical devices across cardiology, orthopaedics, surgical, and vision.
The market's mental model of J&J has been slow to update. Many investors still think of J&J as the consumer-dominant healthcare conglomerate of the pre-Kenvue era. The current business is materially different. Innovative Medicine is one of the largest pharma franchises globally with a credible pipeline. MedTech is one of the largest medical device businesses globally with a growth acceleration underway.
Historically, healthcare conglomerates that have simplified their structures have seen multiple expansion following the transition. Pfizer's 2020 Viatris separation produced roughly 18 months of outperformance for the remaining business before the COVID cycle distorted the comparison. Merck's 2021 Organon separation produced similar outperformance. J&J's Kenvue separation is still in the early innings of that re-rating.
