Approach 1: Tetra Tech Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow model projects a company’s future cash flows and then discounts them back to today’s dollars, aiming to estimate what the whole business could be worth right now.

For Tetra Tech, the model used is a 2 Stage Free Cash Flow to Equity approach. The latest twelve month Free Cash Flow stands at about $666.7 million. Simply Wall St uses analyst forecasts where available, then extends those trends for later years. In this case, projected Free Cash Flow for 2028 is $435.85 million, with further estimates running out to 2035 based on a mix of analyst inputs and extrapolated figures.

After discounting these projected cash flows, the model arrives at an estimated intrinsic value of around $39.80 per share. Compared with the recent share price of $27.27, this suggests Tetra Tech trades at about a 31.5% discount to that DCF estimate, indicating the stock appears undervalued on this method alone.

Approach 2: Tetra Tech Price vs Earnings

For a profitable company, the P/E ratio is a straightforward way to see how much investors are paying for each dollar of earnings, which makes it a useful cross check against the DCF result you just saw.

What counts as a “normal” P/E depends on how the market views a company’s growth prospects and risk. Higher expected growth or lower perceived risk can support a higher P/E, while slower growth or higher risk typically lines up with a lower one.

Tetra Tech trades on a P/E of 16.08x. That sits below the Commercial Services industry average of 22.05x and well below the peer group average of 31.72x. Simply Wall St also calculates a Fair Ratio of 17.86x, which is the P/E that might be expected given factors such as earnings growth, profit margins, industry, market cap and risk profile.

This Fair Ratio is more tailored than a simple peer or industry comparison, because it is based on Tetra Tech’s own characteristics rather than assuming all companies should trade on the same multiple. With the current P/E of 16.08x sitting below the 17.86x Fair Ratio, the stock screens as undervalued on this earnings based view.

Result: UNDERVALUED

Earlier it was mentioned that there is an even better way to understand valuation, so this is where Narratives come in, giving you a simple story behind your numbers by linking your view on Tetra Tech’s future revenue, earnings and margins to a forecast and then to a Fair Value that you can compare with the current price. All of this happens within the Narratives section on Simply Wall St’s Community page, where millions of investors share their views and where those Narratives update automatically when fresh news or earnings arrive.
