How Should Investors View Comfort Systems USA After the 95% Rally in 2024?

If you’re thinking about what to do with your Comfort Systems USA shares, or maybe whether now is the time to get involved, you’re definitely not alone. This stock has been turning heads lately, and for good reason. After a modest dip of -0.9% in the last week, the share price surged 7.0% over the past month. Zoom out, and those bigger numbers really tell the story: up 95.4% year-to-date, over 100% in the last year, and a staggering 1,463.6% in five years. That kind of consistent outperformance does not just happen by chance. It reflects both bullish investor sentiment and some notable shifts in how the market perceives Comfort Systems USA’s potential for long-term growth.

The company’s impressive run has come during a period of renewed interest in industrial services and infrastructure, as investors respond to changing economic priorities and demand for efficient systems nationwide. But soaring share prices inevitably spark conversations about valuation. Is Comfort Systems USA still undervalued, or has the recent run-up made it too expensive to touch?

Let’s get into that. Our latest analysis scores Comfort Systems USA a 4 out of 6 on our valuation score, meaning the company is considered undervalued in four key metrics. We’ll dig into how this score is calculated and what it really means for investors like you, drawing on several popular valuation methods. And, if you stick around, I’ll share a perspective that might matter even more than most traditional models.

Comfort Systems USA delivered 102.6% returns over the last year. See how this stacks up to the rest of the Construction industry.

Approach 1: Comfort Systems USA Discounted Cash Flow (DCF) Analysis

The Discounted Cash Flow (DCF) approach estimates a company’s fair value by extrapolating its projected future cash flows and discounting them back to today’s terms. This model helps investors gauge what the business is fundamentally worth, without getting caught up in current market sentiment.

For Comfort Systems USA, the most recent data shows its last twelve months (LTM) Free Cash Flow at $557.6 Million. For the next several years, analysts project healthy growth, with year-by-year estimates rising from $860 Million in 2026 to over $1.77 Billion by 2029. After that, Simply Wall St extrapolates continued Free Cash Flow growth through 2035, using reasonable growth rates. All projections are provided in US dollars for consistency with the company’s financial reporting.

Taking all these projected cash flows into account, the DCF analysis arrives at an estimated fair value of $1,092.19 per share for Comfort Systems USA. As of the latest calculation, the stock is trading at a 23.4% discount to this intrinsic value. This suggests the shares are currently undervalued according to this model.

Result: UNDERVALUED

Approach 2: Comfort Systems USA Price vs Earnings (PE)

The Price-to-Earnings (PE) ratio is widely used for valuing profitable companies, as it helps investors understand how much they’re paying for each dollar of a company’s earnings. A company with steady profits and growth prospects is well suited for PE-based analysis, since it reflects both current performance and market expectations for the future.

Growth expectations and risk play a huge role in determining what counts as a “normal” or “fair” PE ratio. Companies expected to grow rapidly often trade at higher multiples, as investors are willing to pay up for future potential. Riskier or slower-growing companies may deserve a lower PE.

Comfort Systems USA’s current PE ratio stands at 42.6x. This is slightly below the Construction industry average of 36.8x, and also below the average of peer companies at 45.2x. Based on these numbers, the company is positioned in the middle of the pack, neither a strong bargain nor extremely overpriced according to standard benchmarks.

However, Simply Wall St’s proprietary "Fair Ratio" provides a more complete picture by incorporating factors like Comfort Systems USA’s earnings growth, profit margins, risk profile, market cap, and industry positioning. The Fair Ratio for the company is 44.1x, which is custom-calculated to reflect what a rational investor would pay, factoring in the company's unique characteristics rather than broad averages.

Because the current PE ratio of 42.6x is quite close to the Fair Ratio of 44.1x, the stock appears fairly valued using this method.

Result: ABOUT RIGHT

Earlier, we mentioned there is an even better way to understand valuation, so let's introduce you to Narratives. A Narrative is simply your own story and outlook for a company.
