Mounjaro (tirzepatide), initially approved for diabetes management, has demonstrated remarkable efficacy in weight loss, leading to its expansion into obesity treatment. Zepbound, a newer entrant targeting obesity directly, further consolidates Lilly's position. The combined sales of these drugs have propelled Lilly to the forefront of the obesity market, challenging established players and redefining treatment paradigms globally. This aggressive market penetration is a key driver behind the company's impressive financial metrics.

Financial Performance and Growth Drivers#

LLY's financial results for fiscal year 2024 highlight the profound impact of its strategic investments. Revenue surged to $45.04 billion, marking a +32% increase from $34.12 billion in 2023 [Monexa AI]. This growth significantly outpaces the company's historical three-year compound annual growth rate (CAGR) for revenue, which stood at +16.73% [Monexa AI], indicating an accelerating growth trajectory fueled by new product uptake. Net income more than doubled, reaching $10.59 billion in 2024 from $5.24 billion in 2023, representing a staggering +102.08% increase [Monexa AI]. This expansion in profitability is also reflected in the net income ratio, which improved to 23.51% in 2024 from 15.36% in 2023 [Monexa AI], demonstrating enhanced operational efficiency and pricing power.

Earnings per share (EPS) mirrored this growth, with a +101.9% increase [Monexa AI], signaling strong shareholder value creation. The company's gross profit ratio also saw a healthy increase, rising from 79.25% in 2023 to 81.31% in 2024 [Monexa AI].

The Powerhouse Duo: Mounjaro and Zepbound#

Tirzepatide, marketed as Mounjaro for diabetes, has experienced exponential growth, with sales increasing by 60% from April to May 2025 in India, reaching approximately ₹12.6 crore ($1.5 million) [Business Standard]. Its dual-action mechanism, targeting both GIP and GLP-1 receptors, offers superior glycemic control and weight loss benefits compared to traditional therapies. The success of Mounjaro underscores LLY's commitment to innovation and its ability to bring highly effective treatments to market.

Its introduction has been strategic, aiming to capture a significant share of the rising obesity treatment market in India and globally [The Hindu]. The rapid uptake of these drugs highlights a critical shift in the obesity treatment paradigm, moving towards highly effective injectable therapies. This shift is translating directly into LLY's financial gains, as evidenced by its substantial revenue and net income growth. The company's ability to consistently deliver innovative products with strong clinical profiles is a core tenet of its long-term strategic effectiveness.

Quantifying Eli Lilly's Market Share and Expansion#

Eli Lilly's share of the obesity market is expanding rapidly, particularly in high-growth emerging markets. As of 2025, Lilly aims for a 60% market share in India alone, where the anti-obesity drug market was valued at ₹576 crore as of March 2025 [Makreo]. This ambitious target demonstrates LLY's aggressive expansion strategy beyond established Western markets. The company's focus on affordability, with Mounjaro pricing ranging from ₹3,500 to ₹4,375 per vial in India [LiveMint], has facilitated wider adoption, especially in a price-sensitive market.

Within the global GLP-1 market, LLY's products are capturing a substantial portion, competing closely with Novo Nordisk's offerings. The company's strategic marketing, combined with robust clinical data, has been instrumental in increasing its market share in this lucrative segment. This proactive approach to market expansion and pricing strategy is crucial for sustaining its high growth rates and building a durable competitive moat. The company's ability to localize its market approach, as seen in India, is a key indicator of effective management execution.

The dividend per share for the TTM is $5.60, with a payout ratio of 43.74% [Monexa AI], suggesting a balanced approach between reinvestment and shareholder returns. The company's ability to service its growing debt while continuing to invest heavily will be a key determinant of its long-term financial stability and strategic flexibility.

Market Reaction and Valuation Context#

Eli Lilly's stock (LLY has reacted positively to its strong performance and dominant position in the obesity market. As of the latest quote, LLY trades at $777.67, with a modest daily change of +$2.22 or +0.29% [Monexa AI]. The company commands a substantial market capitalization of $737.03 billion [Monexa AI], reflecting investor confidence in its growth trajectory and pipeline potential. However, its valuation metrics indicate that much of this optimism is already priced in.

Key Valuation Metrics#

LLY currently trades at a trailing twelve-month (TTM) P/E ratio of 62.91x, significantly higher than the broader market and many pharmaceutical peers [Monexa AI]. Its price-to-sales ratio is 15.04x TTM, and enterprise value over EBITDA (EV/EBITDA) stands at 47.45x TTM [Monexa AI]. These elevated multiples reflect the market's high expectations for future revenue and earnings growth, primarily driven by its GLP-1 franchise. Looking ahead, analyst estimates project a forward P/E of 37.4x for 2025, decreasing to 29.26x for 2026 and 24.04x for 2027 [Monexa AI]. Similarly, forward EV/EBITDA is estimated at 41.75x for 2025, declining to 34.71x for 2026 [Monexa AI].

These forward multiples, while still premium, suggest an anticipated normalization as earnings catch up to the stock price, assuming the company meets its aggressive growth targets. The high valuation indicates that investors are betting on [LLY](/dashboard/companies/LLY]'s ability to continue dominating the GLP-1 market and successfully bring new innovations to fruition. This high-growth valuation contrasts sharply with historical pharma valuations, reflecting the unprecedented market opportunity presented by obesity drugs.
