Accenture PLC (NYSE:ACN)

The valuation ratios exhibit a cyclical pattern characterized by a significant peak in late 2021, a correction throughout 2022, a period of stabilization and moderate recovery between 2023 and 2024, and a sharp contraction in valuation multiples beginning in early 2025 and continuing through May 2026.

Price to Earnings (P/E) Ratio

The P/E ratio reached a maximum of 40.88 in November 2021 before experiencing a decline to 22.93 by August 2022. Following this trough, the ratio recovered to a peak of 31.14 in November 2023. However, a sustained downward trajectory is observed from November 2024 (30.76), culminating in a significant drop to 10.06 by May 2026.

Price to Operating Profit (P/OP) Ratio

Mirroring the P/E trend, the P/OP ratio peaked at 31.03 in November 2021 and bottomed at 16.83 in August 2022. A secondary recovery phase saw the ratio rise back to 24.43 in February 2024. A precipitous decline followed, with the ratio falling to 7.40 by the end of the observed period in May 2026.

Price to Sales (P/S) Ratio

The P/S ratio shifted from a high of 4.72 in November 2021 to a low of 2.56 in August 2022. After fluctuating between 2.72 and 3.51 from February 2023 through November 2024, the ratio entered a sharp decline, reaching a period low of 1.07 in May 2026.

Price to Book Value (P/BV) Ratio

The P/BV ratio exhibited the most pronounced volatility, peaking at 12.45 in November 2021. After a correction to 7.13 in August 2022 and a subsequent stabilization around the 8.00 mark in late 2023, the ratio declined steadily. This contraction accelerated in 2025, ending at 2.46 in May 2026.

A high degree of correlation is observed across all four valuation metrics, suggesting that the fluctuations are primarily driven by changes in market price rather than isolated shifts in earnings, sales, or book value. The consistent and steep decline across all ratios starting in early 2025 indicates a significant compression in market valuation multiples.

The financial data reveals a divergence between fundamental earnings growth and market valuation over the analyzed period. While earnings per share exhibited a consistent upward trajectory, the price-to-earnings ratio experienced significant volatility, culminating in a sharp valuation contraction in the final quarters.

Earnings Per Share (EPS) Performance

Earnings per share demonstrated steady growth, rising from 8.27 US$ in November 2020 to 12.72 US$ by May 2026. This consistent increase indicates a strengthening of the underlying profitability and fundamental operational performance throughout the period.

P/E Ratio Fluctuations and Peak Valuation

The P/E ratio underwent several distinct phases. An initial expansion phase occurred between November 2020 and November 2021, where the ratio climbed from 31.97 to a peak of 40.88. This peak coincided with the highest share price recorded in the set at 400.60 US$. A subsequent correction followed, with the ratio dropping to 22.93 by August 2022, reflecting a shift in market sentiment or valuation adjustments.

Mid-Term Stability

From August 2022 through November 2024, the P/E ratio remained relatively stable, fluctuating within a range of 23.64 to 31.14. During this period, share prices and earnings moved in a more synchronized manner, maintaining a valuation multiple consistent with previous historical norms.

Terminal Valuation Compression

A pronounced downward trend in valuation is observed starting in February 2025. Despite EPS continuing to rise to 12.72 US$, the share price declined sharply to 127.98 US$ by May 2026. This resulted in the P/E ratio compressing from 24.53 in February 2025 to a period low of 10.06 in May 2026, representing a significant reduction in the multiple the market was willing to pay for each dollar of earnings.

The analysis of the valuation ratios reveals a significant divergence between operational performance and market valuation over the observed period. While operating profit per share maintained a generally positive trajectory, the share price exhibited high volatility, resulting in substantial fluctuations in the Price to Operating Profit (P/OP) ratio.

Share Price Trends

The share price experienced an initial expansion phase, peaking at 400.60 in November 2021. This was followed by a period of correction and subsequent volatility, with a secondary peak of 372.16 in November 2024. However, a severe downward trend is evident starting in February 2025, with the price declining sharply to 127.98 by May 2026.

Operating Profit per Share Performance

Operating profit per share demonstrated consistent growth and resilience. Starting at 10.46 in November 2020, the figure rose steadily to 15.11 by November 2022. Despite minor fluctuations between 2023 and early 2024, the trend resumed an upward trajectory, reaching a period high of 17.30 by May 2026. This indicates that fundamental operational efficiency improved regardless of market sentiment.

Price to Operating Profit (P/OP) Ratio Analysis

The P/OP ratio reflects the impact of the decoupling between market price and operational earnings. The ratio peaked at 31.03 in November 2021, aligning with the share price peak. A notable contraction occurred in August 2022, dropping to 16.83. While the ratio stabilized between 20.00 and 24.00 for several quarters, it entered a precipitous decline in 2025 and 2026. The ratio fell to 7.40 by May 2026, the lowest point in the series, driven by a collapse in share price despite the simultaneous increase in operating profit per share.

The analysis of the price-to-sales (P/S) ratio reveals a period of significant valuation volatility that stands in contrast to a consistent, linear increase in sales per share. While revenue generation per share grew steadily over the observed period, the market valuation of those sales fluctuated sharply, ending in a substantial contraction.

Sales Performance Trends

Sales per share demonstrated an uninterrupted upward trajectory, increasing from 70.47 US$ in November 2020 to 119.40 US$ by May 2026. This represents a sustained growth in operational revenue efficiency per share regardless of market price fluctuations.

Valuation Expansion and Peak

An initial expansion in the P/S ratio is observed from November 2020 through November 2021, where the ratio climbed from 3.75 to a peak of 4.72. This period coincided with a rise in share price from 264.47 US$ to 400.60 US$, indicating increasing investor confidence and a higher premium placed on each dollar of revenue.

Intermediate Volatility and Correction

A significant valuation correction occurred between February 2022 and August 2022, with the P/S ratio dropping from 3.57 to 2.56. A subsequent recovery phase took place between February 2023 and November 2024, during which the ratio stabilized and peaked again at 3.51. During this window, the share price experienced intermittent volatility but generally maintained a range between 271.66 US$ and 372.16 US$.

Severe Valuation Compression

A sharp decline in the P/S ratio is evident starting in February 2025 and accelerating through May 2026. Despite sales per share continuing to rise to 119.40 US$, the share price plummeted to 127.98 US$. This resulted in the P/S ratio falling to 1.07, the lowest point in the analyzed period, signaling a fundamental shift in market valuation or a significant decrease in the premium assigned to the company's revenue stream.

The financial data reveals a significant divergence between the steady growth of the book value per share and the volatility of the market price, resulting in a long-term compression of the price-to-book value (P/BV) ratio. While the underlying accounting value of the equity has increased consistently throughout the period, the market valuation premium has diminished substantially.

Book Value per Share (BVPS) Trend

A consistent and linear upward trajectory is observed in the book value per share, rising from 28.21 US$ in November 2020 to 52.09 US$ by May 2026. This steady growth indicates a continuous accumulation of net assets and retained earnings over the analyzed period.

Share Price Volatility

The share price exhibited significant fluctuations, reaching an initial peak of 400.60 US$ in November 2021. Following a period of volatility and a secondary peak of 372.16 US$ in November 2024, a sharp decline occurred toward the end of the sequence, with the price falling to 127.98 US$ by May 2026.

P/BV Ratio Dynamics

The P/BV ratio transitioned through three distinct phases: 1. Expansion: An initial increase from 9.38 in November 2020 to a peak of 12.45 in November 2021. 2. Stabilization: A correction and subsequent plateau where the ratio generally fluctuated between 6.92 and 8.03 from August 2022 through May 2024. 3. Contraction: A sustained and accelerating decline starting in February 2025, ultimately reaching a period low of 2.46 in May 2026.

The overall analysis indicates that the market's willingness to pay a premium over the book value has eroded. The collapse of the P/BV ratio in the final quarters is primarily driven by the precipitous drop in share price, which occurred even as the book value per share continued its steady ascent.
