Tetra Tech (TTEK) Stock Forecast and Price Target (2026)

The average target of $40.50 sits above the $34.72 price, +16.6%. The median is $40.00, and where the two differ the median is the steadier read, because one unusually high or low target cannot drag it.

The published targets span $37.00 to $46.00. That gap is 22% of the average target, which counts as narrow disagreement. A spread that tight means the analysts broadly agree on the model, so the consensus is a reasonably stable read rather than an average of wildly different views.

The useful move is to read the high target as one bull scenario and the low target as one bear scenario, then ask which set of assumptions you find more plausible. Both cases are worked through on the TTEK is it a buy page.

In the last six months there have been 0 raises and 3 cuts among these actions. The direction of revisions is often more telling than the level, because it shows which way informed opinion is moving.

Of the analysts with a published rating, 5 say buy, 3 say hold, and 0 say sell, so 63% carry a buy. That mix has been broadly steady over the last three months.

Read the distribution rather than the label. Sell ratings are rare across the entire market for structural reasons, so a stock with no sell ratings is unremarkable, while even a handful of them is worth understanding.

• It is a 12-month model output. An analyst picks assumptions for revenue, margin, and a multiple, and the target falls out of the arithmetic. Change one assumption and the target moves a lot.
• The distribution is skewed. Sell-side coverage carries far more buy ratings than sell ratings across the whole market, so the average is not a balanced vote.
• Targets follow price as often as they lead it. Revisions frequently arrive after a move, not before, which is why a rising target is weak evidence on its own.
• Nobody is scored on it. There is no cost to a target that never gets close, so treat accuracy as unverified unless you check the firm's record yourself.

For the fiscal year ending Sep 2026, the 7 analysts publishing estimates on TTEK expect earnings of $1.58 per share (+1.1% on the year before) and revenue of $4.4 billion (-5.7%).

Estimates are the most widely published forecast there is: many more analysts model a company's earnings than publish a price target on it. They are also revised constantly, and the direction of those revisions into a report is often more informative than the level. Tetra Tech next reports on November 11, 2026, which is when these figures get tested against actual results.

Not a published one. Analyst price targets run to about twelve months, occasionally two years, and the firms covering TTEK do not put out a 2030 number. Anything presenting one is extrapolating a growth rate rather than reporting research, and a figure produced that way tells you about the assumption chosen, not about the company.

The furthest-out consensus that exists is for the fiscal year ending Sep 2027: analysts expect earnings of $1.72 per share, +9.1% on the fiscal year ending Sep 2026 estimate of $1.58. Beyond that, nobody publishes estimates, so any later number is an extrapolation.

On the figures we hold as of October 2026, TTEK trades at about 20.9 times trailing earnings and 20.3 times forward earnings. A forward multiple below the trailing one means the market expects earnings to grow, and the size of that gap is roughly how much growth is already in the price.

That is the more useful frame for a ten-year question. A share price is the market’s estimate of future cash flows discounted to today, so the multiple is already a statement about growth. The long-horizon question is whether Tetra Tech can deliver what is priced in, and what would have to change for that to break. Both are answerable from the drivers and risks below. A number for 2030 is not.

In short: the drivers cited most often are Water and environmental infrastructure demand, Returning to growth after the funding pause, Margin discipline. The risk cited most often against it is the biggest risk is dependence on government spending, shown vividly when a USAID and State Department funding pause cut roughly $200 million in one quarter and hundreds of millions in annualized revenue; trailing revenue is still running about 4 percent below a year ago.

Both sides are worked through properly, with the high and low targets used as the bull and bear anchors, on the TTEK is it a buy page. This page deliberately stops at the numbers.
