Philip Morris International Inc. (NYSE:PM)

The price-to-book value (P/BV) ratio exhibits significant fluctuation over the observed period. Initially, the ratio demonstrates a substantial increase, followed by periods of instability and, ultimately, a return to more moderate levels, though remaining elevated compared to the beginning of the period.

Initial Increase (2009-2011)

From February 2009 to February 2011, the P/BV ratio increased markedly, moving from 9.14 to 31.91. This suggests a growing investor confidence in the company’s future earnings potential relative to its book value, or potentially an overvaluation of the share price. The share price increased substantially during this period, while the book value per share decreased.

Extreme Fluctuation (2012)

In February 2012, the P/BV ratio reached an exceptionally high value of 624.24. This dramatic increase coincided with a significant rise in share price and a substantial decrease in book value per share, which became a positive value. This suggests a considerable disconnect between market valuation and the company’s net asset value. The negative book value per share is an unusual circumstance that warrants further investigation.

Negative Book Values (2013-2018)

From February 2013 through February 2018, the book value per share remained negative, ranging from -2.11 to -8.18. Consequently, the P/BV ratio is not calculable for these years. The persistent negative book value indicates significant accumulated losses or substantial share repurchases exceeding retained earnings.

Continued Negative Book Values & Moderate P/BV (2019-2023)

The book value per share remained negative through February 2023, fluctuating between -5.78 and -8.07. The P/BV ratio remained undefined during this period. The share price experienced fluctuations, but the negative book value continued to prevent meaningful P/BV ratio calculation.

Recent Trend (2024-2026)

In February 2024, the P/BV ratio is again calculable, reaching 18.23. This is due to the book value per share becoming a negative value again. The P/BV ratio increased to 24.38 in February 2025 and 28.68 in February 2026, alongside increases in share price. This suggests a renewed investor willingness to pay a premium for each dollar of book value, despite the continued negative book value.

Overall, the P/BV ratio demonstrates a complex pattern, heavily influenced by fluctuations in both share price and, critically, book value per share. The extended period of negative book values significantly impacts the interpretability of the ratio, and the recent increases in P/BV alongside continued negative book values suggest a potentially speculative market valuation.
