Estimating The Fair Value Of Tetra Tech, Inc. (NASDAQ:TTEK)
Key Insights
- Tetra Tech's estimated fair value is US$248 based on 2 Stage Free Cash Flow to Equity
- Current share price of US$236 suggests Tetra Tech is potentially trading close to its fair value
- Analyst price target for TTEK is US$251, which is 1.1% above our fair value estimate
Today we will run through one way of estimating the intrinsic value of Tetra Tech, Inc. (NASDAQ:TTEK) by taking the expected future cash flows and discounting them to today's value. We will use the Discounted Cash Flow (DCF) model on this occasion. It may sound complicated, but actually it is quite simple!
Companies can be valued in a lot of ways, so we would point out that a DCF is not perfect for every situation. For those who are keen learners of equity analysis, the Simply Wall St analysis model here may be something of interest to you.

Is Tetra Tech Fairly Valued?
We use what is known as a 2-stage model, which simply means we have two different periods of growth rates for the company's cash flows. Generally the first stage is higher growth, and the second stage is a lower growth phase. In the first stage we need to estimate the cash flows to the business over the next ten years. Where possible we use analyst estimates, but when these aren't available we extrapolate the previous free cash flow (FCF) from the last estimate or reported value. We assume companies with shrinking free cash flow will slow their rate of shrinkage, and that companies with growing free cash flow will see their growth rate slow, over this period. We do this to reflect that growth tends to slow more in the early years than it does in later years.
A DCF is all about the idea that a dollar in the future is less valuable than a dollar today, and so the sum of these future cash flows is then discounted to today's value:
10-year free cash flow (FCF) estimate
2025 | 2026 | 2027 | 2028 | 2029 | 2030 | 2031 | 2032 | 2033 | 2034 | |
Levered FCF ($, Millions) | US$467.3m | US$476.3m | US$482.9m | US$542.1m | US$564.0m | US$584.1m | US$603.1m | US$621.4m | US$639.2m | US$656.8m |
Growth Rate Estimate Source | Analyst x3 | Analyst x2 | Analyst x1 | Analyst x1 | Est @ 4.04% | Est @ 3.57% | Est @ 3.25% | Est @ 3.03% | Est @ 2.87% | Est @ 2.76% |
Present Value ($, Millions) Discounted @ 6.4% | US$439 | US$421 | US$401 | US$423 | US$414 | US$403 | US$391 | US$378 | US$366 | US$353 |
("Est" = FCF growth rate estimated by Simply Wall St)
Present Value of 10-year Cash Flow (PVCF) = US$4.0b
The second stage is also known as Terminal Value, this is the business's cash flow after the first stage. For a number of reasons a very conservative growth rate is used that cannot exceed that of a country's GDP growth. In this case we have used the 5-year average of the 10-year government bond yield (2.5%) to estimate future growth. In the same way as with the 10-year 'growth' period, we discount future cash flows to today's value, using a cost of equity of 6.4%.
Terminal Value (TV)= FCF2034 × (1 + g) ÷ (r – g) = US$657m× (1 + 2.5%) ÷ (6.4%– 2.5%) = US$17b
Present Value of Terminal Value (PVTV)= TV / (1 + r)10= US$17b÷ ( 1 + 6.4%)10= US$9.3b
The total value is the sum of cash flows for the next ten years plus the discounted terminal value, which results in the Total Equity Value, which in this case is US$13b. To get the intrinsic value per share, we divide this by the total number of shares outstanding. Relative to the current share price of US$236, the company appears about fair value at a 4.9% discount to where the stock price trades currently. The assumptions in any calculation have a big impact on the valuation, so it is better to view this as a rough estimate, not precise down to the last cent.
Important Assumptions
Now the most important inputs to a discounted cash flow are the discount rate, and of course, the actual cash flows. If you don't agree with these result, have a go at the calculation yourself and play with the assumptions. The DCF also does not consider the possible cyclicality of an industry, or a company's future capital requirements, so it does not give a full picture of a company's potential performance. Given that we are looking at Tetra Tech as potential shareholders, the cost of equity is used as the discount rate, rather than the cost of capital (or weighted average cost of capital, WACC) which accounts for debt. In this calculation we've used 6.4%, which is based on a levered beta of 0.947. Beta is a measure of a stock's volatility, compared to the market as a whole. We get our beta from the industry average beta of globally comparable companies, with an imposed limit between 0.8 and 2.0, which is a reasonable range for a stable business.
SWOT Analysis for Tetra Tech
- Debt is not viewed as a risk.
- Earnings declined over the past year.
- Dividend is low compared to the top 25% of dividend payers in the Commercial Services market.
- Annual earnings are forecast to grow for the next 3 years.
- Current share price is below our estimate of fair value.
- Annual earnings are forecast to grow slower than the American market.
Moving On:
Whilst important, the DCF calculation shouldn't be the only metric you look at when researching a company. DCF models are not the be-all and end-all of investment valuation. Instead the best use for a DCF model is to test certain assumptions and theories to see if they would lead to the company being undervalued or overvalued. If a company grows at a different rate, or if its cost of equity or risk free rate changes sharply, the output can look very different. For Tetra Tech, we've put together three important items you should look at:
