Outlook and guidance

  • 2024 revenue guidance is $40.4B–$41.6B; growth is expected to be led by New Products and partly offset by continued Trulicity declines.

  • 2024 GAAP EPS guidance is $11.80–$12.30 and non-GAAP adjusted EPS is $12.20–$12.70, including a $0.40 amortization adjustment.

  • Gross margin guidance is 80%–82% GAAP and 81%–83% non-GAAP; the (gross margin less OPEX)/revenue ratios are 30%–32% reported and 31%–33% non-GAAP.

  • R&D and SG&A are expected to rise with late-stage programs and launches, with R&D growing faster than marketing and selling costs; other expense is $400M–$500M and tax rate ~14%.

  • Outlook reflects launch momentum, geographic growth, second-half injectable incretin capacity expansion, Trulicity erosion and high-single-digit net price decline excluding divestitures; demand is expected to exceed supply.
