Price-to-Earnings of 24x: Is it justified?

Nippon Gas trades at a price-to-earnings ratio of 24x, significantly higher than both its industry peers and what models suggest it should be. With a recent close price of ¥2,954, this places Nippon Gas in the premium valuation zone compared to its sector.

The price-to-earnings multiple is a quick snapshot of how much investors are willing to pay for each yen of the company’s annual earnings. In defensive sectors like utilities, investors often look for steady and predictable earnings. A high multiple can signal the expectation of strong profit growth or deeper market confidence.

Currently, the company’s price-to-earnings ratio stands well above the Asian Gas Utilities industry average of 13.9x and the peer average of 11x. More strikingly, it is nearly triple the estimated fair price-to-earnings ratio of 8.3x, hinting at lofty market expectations or possible over-enthusiasm around recent performance. If the market readjusts toward the fair ratio, significant repricing is possible.

Result: Price-to-Earnings of 24x (OVERVALUED)

However, slowing revenue growth and the stock’s existing rally could limit further upside if market enthusiasm fades in the months ahead.

Another View: SWS DCF Model Points to Opportunity

While the earnings multiple signals overvaluation, our DCF model tells a different story. According to this approach, Nippon Gas is trading below its estimated fair value by roughly 16.8%.

Market enthusiasm for earnings, or a more patient take on cash flow potential?
