Eli Lilly & Co. (NYSE:LLY)

The valuation metrics exhibit a distinct cyclical pattern characterized by a period of aggressive multiple expansion from early 2022 through late 2023, followed by a sustained trend of multiple compression through the first quarter of 2026. All four analyzed ratios reached their peak in the fourth quarter of 2023, indicating a synchronized surge in market valuation relative to fundamental financial markers.

Price to Earnings (P/E) Ratio

The P/E ratio grew from 45.29 in March 2022 to a peak of 135.24 by December 2023. Following this apex, the ratio entered a downward trajectory, falling to 120.94 in March 2024 and continuing a general decline to reach 34.82 by March 2026. This represents a significant correction, with the final value falling below the initial 2022 levels.

Price to Operating Profit (P/OP) Ratio

Mirroring the P/E trend, the P/OP ratio rose from 36.49 in March 2022 to a high of 109.75 in December 2023. A consistent decrease was observed thereafter, with the ratio declining to 27.92 by March 2026. The trajectory suggests that the valuation premium attributed to operating profitability expanded and contracted in tandem with overall earnings valuations.

Price to Sales (P/S) Ratio

The P/S ratio increased from 9.47 in March 2022, peaking at 20.77 in December 2023. After this peak, the ratio experienced a gradual reduction, reaching 12.18 by March 2026. Although the ratio declined after 2023, it remained higher than the starting 2022 baseline for the majority of the period analyzed.

Price to Book Value (P/BV) Ratio

The P/BV ratio demonstrated the most significant relative volatility, climbing from 29.75 in March 2022 to a peak of 65.80 in December 2023. The subsequent compression was sharp, with the ratio returning to 28.21 by March 2026, effectively erasing the premium gains accumulated over the preceding three years.

The alignment of these peaks in December 2023 suggests a period of maximum market optimism or speculative pricing that was not sustained. The subsequent decline across all ratios indicates a systemic realignment of the stock price toward more conservative fundamental valuations. By the end of the observed period in March 2026, the valuation multiples for earnings, operating profit, and book value had all retreated to levels lower than those recorded in March 2022.

The analyzed period is characterized by a significant expansion in valuation followed by a period of normalization driven by accelerating earnings growth. The interaction between share price appreciation and earnings per share (EPS) resulted in a volatile P/E ratio that peaked in late 2023 before entering a sustained downward trend.

Share Price Movement

A consistent upward trajectory is observed from March 2022 through December 2024, with the price increasing from $292.13 to $867.05. Although a temporary correction occurred in the first half of 2025, reaching a low of $640.86 in June 2025, the price recovered to reach a peak of $1,038.27 by December 2025 before settling at $934.60 in March 2026.

Earnings Per Share Growth

EPS remained relatively stable between March 2022 and March 2023, fluctuating within a narrow range between $5.99 and $6.84. A period of rapid acceleration began in late 2024, with EPS rising from $11.17 in September 2024 to $26.84 by March 2026, indicating a substantial increase in profitability per share over the latter half of the period.

P/E Ratio Dynamics

The P/E ratio experienced a sharp escalation, rising from 45.29 in March 2022 to a peak of 135.24 in December 2023. This indicates a phase where share price growth significantly outpaced earnings growth. Following this peak, the ratio entered a steady decline, falling to 34.82 by March 2026. This compression in the valuation multiple is attributed to the convergence of the accelerating EPS growth and the stabilization of the share price, moving the valuation toward a more conservative level relative to earnings.

The financial trajectory from March 2022 through March 2026 is characterized by a significant expansion and subsequent contraction of the Price to Operating Profit (P/OP) ratio, reflecting a shift from valuation driven by market expectations to valuation supported by fundamental operational growth.

Share Price Evolution

An overall upward trend is observed, with the share price increasing from 292.13 US$ in March 2022 to a peak of 1,038.27 US$ in December 2025. Significant acceleration occurred between June 2023 and December 2023, where the price rose from 521.60 US$ to 745.91 US$. Despite a temporary decline in the first half of 2025, the price remained substantially elevated compared to 2022 levels.

Operating Profit per Share Performance

Operating profit per share exhibited a U-shaped recovery followed by aggressive growth. After a period of stagnation and decline reaching a low of 6.22 US$ in September 2023, a sharp upward trend commenced. Operating profit per share grew from 6.80 US$ in December 2023 to 33.47 US$ by March 2026, representing a substantial increase in operational efficiency and profitability over the final two years of the period.

P/OP Ratio Dynamics

The P/OP ratio experienced extreme volatility, peaking at 109.75 in December 2023. This peak was the result of the share price appreciating rapidly while operating profits were concurrently declining or stagnant. Following this peak, a consistent downward trend is observed, with the ratio compressing to 27.92 by March 2026. This compression indicates that the growth in operating profit per share began to outpace the growth in share price.

The observed patterns indicate a period of valuation decoupling during 2022 and 2023, where the market priced in future growth far in advance of operational realization. The subsequent decline in the P/OP ratio from 2024 onward demonstrates a fundamental realignment, as the surge in operating profit per share provided the necessary financial justification for the higher share price levels.

The valuation profile of the common stock exhibits a period of significant expansion in the Price to Sales (P/S) ratio, followed by a corrective phase and subsequent stabilization. While the share price and sales per share both trended upward over the observed period, the rate of increase in share price initially far outpaced the growth in sales, leading to a peak in valuation multiples before the fundamental sales growth began to align more closely with the market price.

Share Price Trajectory

The share price demonstrated a strong long-term upward trend, rising from 292.13 USD in March 2022 to a peak of 1,038.27 USD in December 2025. Although the progression was generally positive, volatility emerged in 2025, characterized by a dip to 640.86 USD in June 2025 before recovering and eventually settling at 934.60 USD by March 2026.

Sales per Share Performance

Fundamental revenue performance showed consistent and accelerating growth. Sales per share remained relatively flat through 2022, hovering around 30 USD. However, from March 2023 onward, a steady climb is observed, with sales per share increasing from 29.17 USD to 76.72 USD by March 2026. This represents a significant improvement in the underlying revenue generation per share over the analyzed timeframe.

Price to Sales (P/S) Ratio Analysis

The P/S ratio underwent three distinct phases. From March 2022 to December 2022, the ratio remained moderate, fluctuating between 9.47 and 11.46. A period of rapid valuation expansion occurred throughout 2023, with the ratio peaking at 20.77 in December 2023, suggesting that market expectations grew significantly faster than realized sales. Following a plateau in early 2024, a contraction phase occurred, bringing the ratio down to 11.39 by June 2025. The final period showed continued volatility, with the ratio ending at 12.18 in March 2026, indicating a normalization of the valuation relative to the increased sales per share.

The valuation metrics for the period between March 2022 and March 2026 reveal a period of significant market premium followed by a gradual normalization of the price-to-book relationship. While both the share price and book value per share trended upward over the long term, the rate of change differed substantially, leading to high volatility in the P/BV ratio.

Share Price Dynamics

The share price experienced a strong bullish trend, rising from 292.13 US$ in March 2022 to a peak of 1,038.27 US$ by December 2025. A period of rapid acceleration is observed between March 2023 and December 2023, where the price climbed from 390.35 US$ to 745.91 US$. Although some volatility occurred in mid-2025, the overall trajectory remained positive until a slight correction to 934.60 US$ by March 2026.

Book Value Per Share (BVPS) Growth

BVPS maintained a consistent upward trajectory throughout the analyzed period. Starting at 9.82 US$ in March 2022, growth was initially gradual, remaining under 12.00 US$ through late 2023. However, a marked acceleration in book value growth occurred starting in early 2024, with the value increasing to 33.13 US$ by March 2026. This represents a more than three-fold increase in the underlying accounting value per share over the timeframe.

Price to Book Value (P/BV) Analysis

The P/BV ratio exhibited a pronounced cycle of expansion and contraction. The ratio rose from 29.75 in March 2022 to a peak of 65.80 in December 2023, indicating that the market price was increasing at a rate far exceeding the growth of the company's book value. Following this peak, the ratio entered a phase of gradual decline. Despite the share price remaining at elevated levels, the accelerating growth of the BVPS in 2025 and 2026 drove the P/BV ratio downward. By March 2026, the ratio reached 28.21, returning to a level slightly below the initial March 2022 valuation.

In summary, the data indicates a valuation peak in late 2023 characterized by an extreme premium over book value. The subsequent decline in the P/BV ratio was not primarily driven by a collapse in share price, but rather by a substantial increase in the book value per share, which effectively lowered the valuation multiple by March 2026.
