Key Developments Driving Growth#
Mounjaro and Zepbound: Cornerstones of Market Leadership#
Mounjaro (tirzepatide) has rapidly become a dominant therapy for obesity and type 2 diabetes, generating about $2.3 billion in Q1 2025 sales alone—a remarkable 347% year-over-year growth. This success stems from its dual-action mechanism targeting both GIP and GLP-1 receptors, resulting in superior weight loss and glycemic control compared to traditional treatments.

Pipeline Innovations: Orforglipron and Retatrutide#
Lilly’s next-generation candidates, orforglipron and retatrutide, are poised to extend market dominance. Orforglipron, currently in Phase 3 trials, is projected to generate $11.8 billion in annual sales by 2030. It delivers approximately 7.9% weight loss and reduces HbA1c by 1.6%, offering a competitive alternative within GLP-1 therapies Clinical Trials Arena.
Retatrutide, with Phase 2 data showing up to 24.2% weight loss, represents a potential game-changer, reinforcing Lilly’s strategy to innovate beyond current standards and compete aggressively against peers like Novo Nordisk and Amgen A Invest News.
Strategic Acquisitions: Kisunla and Verve Therapeutics#
Diversification beyond metabolic health is a strategic priority, illustrated by acquisitions of Kisunla and Verve Therapeutics. Kisunla enhances Lilly’s footprint in neurodegenerative diseases, particularly Alzheimer’s, while Verve Therapeutics adds cardiovascular genetic medicine capabilities. These moves reduce reliance on obesity drugs and broaden Lilly’s long-term growth avenues Monexa Blog.
Financial Performance and Metrics#
Revenue and Profit Growth#
Eli Lilly’s fiscal year 2024 results reflect strong financial execution amid rapid expansion. Revenue jumped to $45.04 billion, up +32% from $34.12 billion in 2023.

Cash Flow and Balance Sheet Strength#
Operating cash flow nearly doubled to $8.82 billion (+107.96%) in 2024, supporting a free cash flow of $414 million despite a significant capital expenditure increase to $8.4 billion. Lilly’s investments in property, plant, and equipment reflect capacity expansion and R&D infrastructure enhancement.
The balance sheet remains robust, with total assets growing to $78.71 billion and equity rising to $14.19 billion. Net debt increased to $30.38 billion, primarily due to acquisition activity and capital investments, but the net debt-to-EBITDA ratio of 2.18x remains manageable within industry standards.

Competitive Landscape#
Eli Lilly operates in a fiercely competitive environment dominated by players like Novo Nordisk and Amgen. Novo Nordisk’s Wegovy remains a key competitor, but Lilly’s Zepbound is rapidly gaining share, capturing 75% of new obesity treatment starts, signaling a shift in clinician preference. Novo Nordisk’s market share of 51% in the incretin market is closely contested by Lilly’s near 49% share TradingView.
Amgen’s recent obesity drug Maritide has shown promising Phase 2 results but has yet to achieve the market penetration of Lilly’s offerings, highlighting the competitive advantage of Lilly’s early investments and robust clinical data PharmaPhorum.
Regulatory and pricing pressures remain challenges industry-wide. Lilly’s proactive approach to regulatory pathways and pricing strategies is critical to maintaining access and market share.
What Drives Eli Lilly’s Dominance in the Obesity Drug Market?#
