Financial Impact Assessment

Performance Context

• Revenue Scale: The full-year revenue of $2.987 billion represents approximately 6.9% of the company's $43.35 billion market capitalization, demonstrating a strong revenue generation capability for a company of its size.
• Profitability Milestone: Achieving both GAAP and non-GAAP profitability is a critical milestone for a biopharmaceutical company, indicating that commercial sales are now robust enough to cover significant R&D and SG&A expenditures. This fundamentally changes the investment thesis from a speculative growth story to a profitable enterprise.
• Forward Guidance: The 2026 net product revenue guidance of $4.9B - $5.3B implies a further 64% - 77% YoY growth, signaling strong continued momentum.
