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

A Discounted Cash Flow, or DCF, model estimates what a company could be worth by projecting future cash flows and then discounting them back to today, using a required rate of return. It is essentially asking what all of Tetra Tech's future cash generation is worth in today's dollars.

For Tetra Tech, the model used is a 2 Stage Free Cash Flow to Equity approach based on cash flow projections. The latest twelve month free cash flow is about $495.3 million. Analyst inputs and extrapolated estimates point to free cash flow of $350.0 million in the 2028 financial year, with a series of projections extending out to 2035 that are discounted back to present value.

Putting these cash flows together, the model arrives at an estimated intrinsic value of US$27.11 per share. Compared with the recent share price of US$30.85, the DCF output suggests the stock is about 13.8% overvalued on this set of assumptions.

Result: OVERVALUED

Approach 2: Tetra Tech Price vs Earnings

For a profitable company like Tetra Tech, the P/E ratio is a useful quick check on how much you are paying for each dollar of current earnings. Investors usually accept a higher P/E when they expect stronger growth or see lower risk, and prefer a lower P/E when growth expectations are more modest or risks feel higher.

Tetra Tech currently trades on a P/E of 22.86x. This is close to the Commercial Services industry average P/E of 23.00x, and below the peer group average of 32.50x, which suggests the shares are not priced at the very high end of their sector.

Simply Wall St's Fair Ratio for Tetra Tech is 23.24x. This is a proprietary estimate of what the P/E could be given the company's earnings profile, industry, profit margins, market cap and risk characteristics. Because it adjusts for these company specific factors, it can be more informative than a straight comparison with broad industry or peer averages. With the current P/E of 22.86x sitting slightly below the Fair Ratio of 23.24x, the shares screen as mildly undervalued on this metric.

Result: UNDERVALUED
