Waste Management Inc. (NYSE:WM)

The financial performance and market valuation of Waste Management Inc. between 2006 and 2022 are characterized by a long-term appreciation in share price and a significant shift in the valuation multiple applied to earnings.

Share Price and Earnings Trends

A consistent upward trajectory in share price is evident, rising from 33.90 US$ in 2006 to 142.68 US$ by 2022. Earnings per share (EPS) remained relatively stable between 2006 and 2013, generally fluctuating between 1.76 US$ and 2.35 US$. A severe contraction in earnings occurred in 2014, where EPS fell to 0.21 US$, before recovering to 2.83 US$ in 2015 and peaking at 4.54 US$ in 2019.

P/E Ratio Volatility and Anomalies

The Price to Earnings (P/E) ratio exhibited relative stability from 2006 to 2013, ranging from 12.94 to 21.15. A significant anomaly is observed in 2014, where the P/E ratio spiked to 197.88. This outlier was driven by a sharp decline in EPS while the share price continued to rise, indicating a temporary decoupling of market price from annual earnings.

Valuation Multiple Expansion

Following the 2014 volatility, a trend of multiple expansion is observable. From 2015 onward, the P/E ratio transitioned from a historical average of approximately 16x to a higher valuation regime. By 2020, the ratio stabilized above 31x, remaining at 32.57 by 2022. This suggests that the market began assigning a higher premium to each dollar of earnings in the latter part of the period analyzed.

Overall, the data indicates that while earnings growth supported the stock's rise, a substantial portion of the share price increase in the final five years of the period was driven by an expansion in the P/E multiple rather than proportional growth in EPS.
