Kinder Morgan Inc. (NYSE:KMI)

The valuation of Kinder Morgan Inc. between 2011 and 2020 experienced a significant transition, moving from a high-premium valuation to a period of correction and subsequent stabilization. The Price to Book Value (P/BV) ratio exhibits a clear downward trajectory over the first half of the decade, followed by a period of relative consistency.

Initial Premium Valuation (2011-2012)

During this period, the P/BV ratio was at its highest, peaking at 7.82 in February 2012. This elevated ratio was driven by share prices exceeding 30 USD while the book value per share remained relatively low, hovering around 4 USD.

Book Value Expansion and Ratio Contraction (2013-2015)

A structural shift occurred in 2013, characterized by a sharp increase in book value per share from 4.13 USD to 13.39 USD. This expansion led to a significant contraction in the P/BV ratio, which declined to a range between 2.53 and 2.78, even as share prices peaked at 42.03 USD in February 2015.

Market Correction and Valuation Trough (2016)

A sharp decline in share price to 15.62 USD in February 2016 resulted in the P/BV ratio falling below the 1.0 threshold, reaching a low of 0.99. This indicates a period where the market valuation of the company dipped slightly below its accounting book value.

Stabilization and Recovery (2017-2020)

From 2017 through 2020, the P/BV ratio entered a phase of stabilization, fluctuating within a narrow band between 1.13 and 1.46. This period is marked by a more consistent relationship between share prices and a book value per share that remained steady, ending the period at 14.90 USD.
