After riding a remarkable multi-year run, Constellation Software’s share price has pulled back sharply in 2025, sliding over 8% just this past week and down nearly 24% year-to-date. While the company’s three-year total shareholder return of 74% still stands out, recent momentum is clearly fading as investors weigh leadership shifts and an evolving competitive landscape.

This recent pullback raises a pivotal question for investors: Is Constellation Software now trading at an attractive discount, or is the market fully accounting for both leadership risks and its future growth potential?

Price-to-Earnings of 79.8x: Is it justified?

Constellation Software is trading at a price-to-earnings (P/E) ratio of 79.8, which signals a significant premium compared to both its peers and the broader Canadian software sector. At a last close price of CA$3385.76, this valuation suggests that investors are pricing in strong future profitability or at least continued execution of its acquisition-led growth model.

The price-to-earnings ratio compares a company’s current market price to its earnings per share and is a popular yardstick for valuing technology and software businesses. High P/E ratios can reflect high expectations for future growth, but can also serve as a warning if earnings momentum slows.

At 79.8x, Constellation Software’s multiple is markedly higher than the Canadian software industry average of 52.1x, and also exceeds the broader peer group average of 59.1x. Notably, the fair P/E ratio based on regression analysis for the company is estimated at 42.5x, which is far below its current level. This highlights the risk that the market could recalibrate its expectations downward if growth does not accelerate.

However, if profitability or acquisition pace slows, or if industry valuations fall, Constellation's current premium could quickly come under pressure.

Another View: What Does the SWS DCF Model Say?

While the market’s high P/E multiple may imply overvaluation, our SWS DCF model presents a different perspective. According to this method, Constellation Software is actually trading about 35% below its estimated fair value, suggesting a possible disconnect between current market sentiment and the company’s future cash flow potential. Could this signal an overlooked opportunity, or is the market pricing in more risk than DCF models capture?
