Approach 1: CECO Environmental Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model takes estimates of a company’s future cash flows and discounts them back to today using a required rate of return, to arrive at an estimate of what the business may be worth per share.

For CECO Environmental, the 2 Stage Free Cash Flow to Equity model starts from last twelve month free cash flow of a loss of $10.7 million, then uses analyst estimates and extrapolated figures to project improving cash flows. By 2028, free cash flow is projected at $132.5 million, with further projections running out to 2035, all expressed in $ and then discounted back to today.

On this basis, the model estimates an intrinsic value of about $85.00 per share, compared with a current share price around $74. The implied discount is 12.8%, which indicates that, under the assumptions of this model, CECO Environmental is trading below this estimate of fair value.

Result: UNDERVALUED

Our Discounted Cash Flow (DCF) analysis suggests CECO Environmental is undervalued by 12.8%. Track this in your watchlist or portfolio, or discover 51 more high quality undervalued stocks.

Approach 2: CECO Environmental Price vs Sales

For companies where revenue is a key focus, the P/S ratio can be a useful way to think about value because it compares what you pay for each dollar of sales, regardless of the current profit level.

In general, higher growth expectations and lower perceived risk can justify a higher P/S multiple, while slower expected growth or higher risk tend to support a lower, more conservative multiple. Therefore, the “right” P/S is rarely a single fixed number and depends on what the market expects from the business.

CECO Environmental currently trades on a P/S ratio of 3.31x. That sits above the broader Machinery industry average of 2.24x and also above the peer group average of 3.07x. To go a step further, Simply Wall St’s Fair Ratio framework estimates what a reasonable P/S might be for CECO Environmental, based on factors such as its growth profile, profit margins, industry and market cap. The Fair Ratio for CECO Environmental is 2.73x, which is designed to be more tailored than a simple comparison with peers or the industry.

Comparing this Fair Ratio of 2.73x with the current P/S of 3.31x suggests CECO Environmental is trading at a premium to that fair value estimate.

Result: OVERVALUED

Upgrade Your Decision Making: Choose your CECO Environmental Narrative

Earlier it was mentioned that there is an even better way to understand valuation, so Narratives on Simply Wall St let you turn your view of CECO Environmental into a clear story that connects assumptions about future revenue, earnings and margins to a forecast and then a Fair Value that you can compare directly to the current share price.

Each Narrative on the Community page is a simple, structured view of that story, showing how your own expectations stack up against others and updating as new earnings, news or guidance come in. This helps your Fair Value view stay linked to the latest information rather than a one off model.

For CECO Environmental, one investor might lean toward the more optimistic Fair Value of about US$103.0 based on higher assumed earnings and a P/E of 42.8x by 2029. Another might align with the more cautious Fair Value of about US$55.0 using slower revenue growth assumptions and a P/E of 41.2x. Narratives make those different views transparent so you can decide where you sit on that spectrum.

For CECO Environmental, here are previews of two leading CECO Environmental Narratives that make the range of market expectations easier to understand:

The first reflects the bullish end of market expectations, built around faster revenue growth, higher margins and a higher Fair Value relative to today. The second sits at the cautious end, with more modest assumptions for growth and profitability that point to a lower Fair Value and a tighter margin of safety.

Fair Value: US$103.00

Implied discount to this Fair Value versus the current US$74.14 share price: about 28.0%.

Revenue growth assumption: 16.69% a year.

• Backlog above US$1b, record orders of US$449 million in Q1 2026 and a sales pipeline of roughly US$7.3b underpin a large pool of contracted and potential work across natural gas, semiconductor, electronics and industrial water markets.
• The pending Thermon combination targets a US$1.5b sales run rate and US$40 million of cost synergies, with expectations for higher EBITDA and potential margin expansion as overlapping customers and products are combined.
• Bullish analysts assume revenue growth of 16.7% a year, profit margins rising from 1.7% to 9.1% and earnings reaching US$115.9 million by 2029, supported by a 42.8x P/E on those earnings and an 8.6% discount rate.

Fair Value: US$55.00

Implied premium to this Fair Value versus the current US$74.14 share price: about 34.6%.

Revenue growth assumption: 12.46% a year.

• Execution risk on large power and natural gas projects, including sizable facilities and a power pipeline that could approach US$2b, may affect project timing, cash conversion and how quickly the current US$793 million backlog and US$1.064b in bookings translate into earnings.
• Industrial water projects in the US and internationally tend to be US$10 million to US$50 million in size with long qualification cycles, while the Thermon integration brings ERP, footprint and synergy execution challenges that could cap margin improvement.
• Bearish analysts assume revenue growth of 12.5% a year, profit margins easing from 6.5% to 5.7% and earnings of US$62.7 million by 2029, with the shares on a 41.2x P/E and an 8.5% discount rate, resulting in a Fair Value of US$55.00 at the low end of the analyst range.
