AbbVie Inc. (NYSE:ABBV)

The valuation ratios exhibit a generalized trend of significant expansion from early 2022 through late 2025, followed by a period of contraction or stabilization in early 2026. This upward trajectory is most pronounced in earnings and book value multiples, suggesting a substantial increase in market valuation relative to fundamental accounting metrics over the observed period.

Price to Earnings (P/E) Ratio

The P/E ratio remained relatively stable between 19.16 and 22.62 throughout 2022. Starting in March 2023, a sharp upward trend emerged, with the ratio climbing from 34.43 to a peak of 159.78 by September 30, 2025. A subsequent correction occurred in the final quarters, with the ratio descending to 94.06 by December 31, 2025, and ending at 97.96 on March 31, 2026.

Price to Operating Profit (P/OP) Ratio

The P/OP ratio followed a trajectory similar to the P/E ratio but with less volatility. After maintaining a range of 14.12 to 14.78 in 2022, the ratio rose steadily to a peak of 42.20 in September 2025. A notable decline was observed thereafter, with the ratio reverting to 23.23 by March 31, 2026, indicating a return toward historical norms.

Price to Sales (P/S) Ratio

The P/S ratio demonstrated the highest degree of stability among the measured metrics. It fluctuated within a narrow band of 4.28 to 4.76 during 2022 and 2023, before experiencing a moderate increase to 6.40 by September 2025. The ratio concluded the period at 5.67, reflecting a modest overall increase in the valuation premium applied to revenue.

Price to Book Value (P/BV) Ratio

The P/BV ratio showed the most aggressive growth pattern. After starting at 16.59 in March 2022, the ratio accelerated rapidly from March 2023 onward. A steep exponential increase is observed between December 2024 (102.40) and March 2025, where the ratio reached 229.63. This indicates a significant divergence between the market price and the company's book value.

Overall, the data indicates a period of intense valuation expansion that peaked in the third quarter of 2025. The simultaneous rise in P/E, P/OP, and P/BV ratios suggests that market expectations significantly outpaced growth in earnings, operating profits, and book value during this window, before a partial correction began in late 2025.

A significant divergence between market valuation and earnings performance is evident over the analyzed period. While the share price maintained a general upward trajectory, earnings per share experienced a sustained decline, resulting in a substantial expansion of the Price-to-Earnings (P/E) ratio.

Share Price Performance

The share price exhibited moderate volatility throughout 2022, ranging between 138.92 US$ and 152.83 US$. Starting in late 2023, a consistent growth trend emerged, with the price ascending from 141.20 US$ in September 2023 to a peak of 224.81 US$ by December 2025. A corrective movement is observed in the first quarter of 2026, with the price adjusting to 201.55 US$.

Earnings per Share (EPS) Trends

EPS remained relatively robust during 2022, peaking at 7.58 US$ in September. However, a precipitous decline began in the first quarter of 2023, where EPS dropped to 4.30 US$. This downward trend persisted through 2024 and 2025, reaching a period low of 1.35 US$ in September 2025. Despite a slight recovery toward the end of 2025, earnings remained significantly below 2022 levels, ending at 2.06 US$ in March 2026.

Price-to-Earnings (P/E) Ratio Expansion

The P/E ratio transitioned from a stable range of approximately 19x to 22x in 2022 to an aggressively expanded valuation. The ratio began to climb sharply in early 2023, surpassing 60x by the end of that year. This expansion accelerated through 2024 and peaked at an extreme valuation of 159.78 in September 2025. The ratio remained elevated through the start of 2026, concluding at 97.96.

Valuation Analysis

The dramatic increase in the P/E ratio is the result of a "scissors effect," where the numerator (share price) increased while the denominator (EPS) decreased. This pattern indicates that market sentiment shifted toward a higher valuation multiple despite weakening quarterly earnings, suggesting that investors may have been pricing in future growth expectations or responding to external market factors rather than current profitability.

An analysis of the valuation metrics reveals a significant divergence between the market price of the equity and the underlying operating profitability from early 2022 through early 2026. While the share price exhibited a general upward trajectory for much of the period, operating profit per share faced a sustained decline, leading to a substantial expansion in the Price to Operating Profit (P/OP) ratio.

Share Price Trends

The share price remained relatively stable between March 2022 and September 2023, fluctuating primarily within the 138 to 152 range. A notable upward shift began in December 2023, with the price climbing steadily through 2024 and 2025. The valuation peaked at 224.81 in December 2025 before experiencing a correction to 201.55 by March 2026.

Operating Profitability Performance

Operating profit per share showed a consistent downward trend starting from a peak of 10.49 in March 2022. Profitability declined steadily throughout 2023 and 2024, reaching a trough of 5.12 in September 2025. This represent a significant reduction in operational earnings power over a three-year period. However, a sharp recovery is observed in the final two quarters, with profit per share rising back to 8.68 by March 2026.

Price to Operating Profit (P/OP) Ratio Analysis

The P/OP ratio remained compressed and stable between 14.12 and 16.55 during the first eighteen months of the period. Beginning in December 2023, the ratio expanded rapidly as the share price rose while operating profits fell. This valuation expansion peaked in September 2025 at 42.20, indicating a period of significant premium pricing relative to operating earnings. The ratio contracted sharply in the final two quarters, falling to 23.23 by March 2026, driven by the simultaneous recovery in operating profits and the correction in share price.

The data indicates that the surge in the P/OP ratio was not driven by earnings growth, but rather by market price appreciation during a period of declining operational efficiency. The eventual contraction of the ratio suggests a realignment of the market valuation with the company's recovered operating performance.

The valuation of the equity based on the price-to-sales (P/S) ratio demonstrates three distinct phases: a period of relative stability, a significant expansion in valuation multiples, and a subsequent correction. The overall trajectory shows a shift from a valuation base in the mid-4x range to a peak above 6x, before returning to a more moderate level by the end of the observed period.

Share Price Volatility and Growth

Share prices exhibited moderate fluctuations between March 2022 and September 2023, trading within a range of approximately 138.92 to 152.83. A bullish trend emerged starting in December 2023, with prices ascending from 175.75 to a peak of 224.81 in December 2025. This upward momentum concluded with a price reduction to 201.55 by March 2026.

Sales per Share Performance

Revenue efficiency per share remained relatively stable, characterized by a slight decline from 32.10 in March 2022 to a trough of 30.75 in December 2023. Following this low point, a consistent growth trend is observed, with sales per share increasing every quarter from March 2024 (30.81) through March 2026, reaching a period high of 35.56.

Price-to-Sales (P/S) Ratio Dynamics

The P/S ratio remained compressed between 4.28 and 4.76 during the first eighteen months of the analysis. A sharp valuation expansion occurred in December 2023, where the ratio jumped to 5.72. This expansion continued through December 2025, peaking at 6.50. This indicates that the share price grew at a significantly faster rate than the underlying sales per share during this interval, suggesting increased market optimism or a re-rating of the company's valuation.

Valuation Correction

A notable divergence occurred in March 2026. While sales per share reached their highest recorded value of 35.56, the P/S ratio contracted to 5.67. This decline in the ratio was driven exclusively by a reduction in the share price, reflecting a contraction in the multiple the market was willing to pay for each dollar of sales.

A significant divergence is observed between the market valuation and the accounting book value of the entity over the analyzed period. While the share price generally trended upward, the book value per share experienced a consistent and severe decline, leading to an exponential increase in the Price to Book Value (P/BV) ratio before the ratio ceased to be applicable due to negative equity.

Share Price Trajectory

The share price exhibited overall growth, moving from 152.83 US$ in March 2022 to a peak of 224.81 US$ in December 2025. Despite some interim volatility, particularly between June and September 2023, the valuation maintained a strong upward bias for the majority of the period, ending at 201.55 US$ in March 2026.

Book Value Per Share (BVPS) Erosion

A continuous downward trend in the book value per share is evident throughout the entire timeline. Beginning at 9.21 US$ in March 2022, the BVPS declined steadily to 1.88 US$ by December 2024. The erosion accelerated in 2025, with the value crossing into negative territory in June 2025 (-0.10 US$) and continuing to fall to -3.77 US$ by March 2026. This indicates a substantial reduction in total shareholders' equity relative to the number of shares outstanding.

Price to Book Value (P/BV) Expansion

The P/BV ratio underwent an aggressive expansion, reflecting the widening gap between market price and book value. The ratio remained relatively stable between 15.52 and 20.62 from March 2022 through September 2023. However, a sharp acceleration began in December 2023 (29.97), climbing rapidly to 102.40 by December 2024 and reaching 229.63 by March 2025. The ratio becomes mathematically undefined or non-reportable following March 2025, as the book value per share turned negative, signifying that the company's liabilities exceeded its assets on a per-share basis.

The combination of rising share prices and collapsing book value suggests that the market valuation is driven by factors entirely independent of the company's balance sheet equity, such as projected future earnings or intangible assets not captured in the book value. The transition to negative book value indicates a capital structure heavily reliant on debt or significant returns of capital to shareholders through buybacks and dividends that exceeded retained earnings.
