Exposure to emerging modalities and collaborations: recent partnerships with Arcturus Therapeutics for RNA therapies and KinetiSol technology integration show investment in next-gen drug manufacturing

Stable financial foundation with $42.9B FY2025 revenue, $6.0B net income, and consistent profitability despite modest YoY decline, providing job security and investment in growth

Watch Out For

Recent layoff activity: 490 total employees affected across 5 WARN filings in 2025–2026 (CA, MA, FL), with the largest (173 employees in CA) as recent as January 2026, signaling restructuring despite revenue scale
Low R&D intensity (3%) and recent R&D budget reduction ($1.5B in FY2024 to $1.3B in FY2025) indicate modest internal drug development ambition; primarily a services/platform play rather than pipeline-driven growth
