Momentum has been building for Taisei, with a 22.5% share price return over the past month and nearly doubling year-to-date. The company’s successful buyback, sharply boosted dividends, and upgraded earnings forecast have all contributed to renewed investor confidence. This is reflected in a remarkable 96.4% total shareholder return over the past year.

Price-to-Earnings of 14.9x: Is it justified?

At a price-to-earnings (P/E) ratio of 14.9 times, Taisei trades below the peer average of 16.4x and stands out relative to the company's recent earnings surge and share price momentum.

The price-to-earnings ratio measures what investors are willing to pay for each unit of profit generated by the company. For an established business like Taisei, this figure is a benchmark for how the market values its current and future profitability.

With earnings growth far outpacing its five-year average, this lower-than-peer P/E may imply the market is underappreciating Taisei’s recent performance. Compared to the wider construction industry, Taisei’s P/E sits above the industry average of 11.6x. This indicates that its strong earnings momentum and upgraded outlook still command a premium to the sector. However, our models suggest a fair P/E of 18.2x, a level the market could shift toward if momentum is sustained.
