Ecolab Inc. (NYSE:ECL)

The valuation of Ecolab Inc. from 2006 to 2022 is characterized by a general expansion in the Price to Operating Profit (P/OP) multiple, coinciding with a substantial increase in share price despite fluctuations in operating profitability.

Share Price Evolution

A consistent long-term upward trajectory is observed in the share price, which rose from 36.19 US$ in 2006 to 180.30 US$ by 2022. Significant acceleration occurred between 2013 and 2020, with the price peaking at 209.36 US$ in 2021 before experiencing a moderate correction.

Operating Profit per Share Performance

Operating profit per share demonstrated a general increase over the period, growing from 2.14 US$ in 2006 to 5.57 US$ in 2022. However, this growth was non-linear. Stability was observed between 2014 and 2020, with values ranging between 6.53 US$ and 6.99 US$. A notable contraction occurred in 2021, where the profit per share dropped to 4.88 US$, representing a significant deviation from the preceding six-year trend.

P/OP Ratio Analysis

The P/OP ratio reveals three distinct valuation phases. Between 2006 and 2011, the ratio remained relatively low, reaching a cyclical trough of 10.54 in 2009. From 2012 to 2020, the ratio transitioned into a higher range, typically fluctuating between 17 and 26, indicating a higher market premium placed on operating earnings. A valuation spike occurred in 2021, with the ratio reaching a peak of 42.88, driven by the combination of a record-high share price and a simultaneous decline in operating profit per share. By 2022, the ratio contracted to 32.34, though it remained significantly elevated compared to historical norms established prior to 2020.

The divergence between share price and operating profit in the final years of the period suggests a shift in market sentiment or valuation methodology, where the stock price became less sensitive to short-term fluctuations in operating profit and more driven by growth expectations or external market multiples.
