Tetra Tech, Inc. paid $0.27 per share over the last four reported quarters. The most recent declaration was $0.07 for Jun 2026. At today's price of $40.94 that is a yield of 0.66%, based on dividends already paid, not a forecast.

A dividend is cash paid out for each share. The 12-month total is the four most recent quarters added together.

Tetra Tech is not in the Nasdaq 100, the S&P 500 or the Dow Jones 30, and is not on the US tech stocks list.

Tetra Tech, Inc. earned $110 M of net profit in the Jun 2026 quarter, −3.7% on the same quarter a year earlier. Full-year FY25 profit was $248 M. Over 4 years profit has grown 1.6% a year on average. That is 9.9% of the quarter's revenue. The same quarter a year earlier earned $114 M.

Net profit is what is left after every cost, interest and tax. Earnings per share, dividends and book value all grow from it.

For the full year, FY25 profit was $248 M (−25.7% on the year before).

Why profit moved: revenue changed −3.9% on a year earlier and the margin moved +0.0 percentage points. Sales did the work, and the margin was about flat.

On average over the last four quarters, profit changed +3,906.7% and revenue −5.2%. Profit is growing faster than sales: fixed costs are spread over more sales, so each extra dollar of revenue adds more to profit.

Tetra Tech, Inc. reported $1.1 B of revenue in the Jun 2026 quarter, −3.9% on the same quarter a year earlier. Over 4 years it has grown 16.0% a year on average. The last full year, FY25, came in at $4.6 B. The last four reported quarters add to $4.4 B.

Revenue is everything the company billed its customers in the period.

FY25 revenue was $4.6 B, +6.8% on the year before.

Recent pace: the last four quarters grew −5.2% on average, against 16.0% a year over the longer run, so this year is growing slower than its own long-run rate.

Is growth speeding up? Revenue over the last 12 months grew −5.2%, against +1.5% a year over the last 8 quarters (rolling over); profit over the last 12 months grew +101.7%, against +22.4% a year (accelerating).

Tetra Tech, Inc.'s operating margin was 14.3% in the Jun 2026 quarter, about the same as the same quarter a year ago. Its latest full-year margin is the highest it has ever reported. Across 5 years it has been between 10.8% and 13.1%. The latest quarter is above every full year in that period.

Operating margin is what is left from every $100 of sales after the costs of running the business, before interest and tax. It shows pricing power and cost control.

In the latest quarter it moved +0.0 percentage points on the same quarter a year ago. Across 5 years it has been between 10.8% and 13.1%, and FY25's 13.1% is the highest of them.

Why the margin moved: operating margin changed +0.0 percentage points on the year while gross margin changed +0.1 points. So the gain came mostly from the gross margin, which means input costs and prices charged.

As noted under valuation: when margins are at a record, every ratio built on profit looks better than usual, so a low multiple can mislead.

Over the last 3 years, 139% of Tetra Tech, Inc.'s reported profit came in as cash from its operations, so the profit is backed by cash. In FY25 it brought in $458 M of operating cash against $248 M of profit. After $18.6 M of spending on assets, $439 M was left over as free cash.

The profit and loss account shows what was earned. The cash-flow statement shows the cash that actually came in. Comparing operating cash flow with profit is one of the best checks that a profit is real.

Cash-flow figures here are yearly, because quarterly cash statements are not published, so this section changes once a year.

Why: the cash figure is clear, but the day counts behind it are not in our data, so we show it without guessing the reason.

What to look at next: the main use of cash is spending on assets. The next section checks what that spending is building.

Tetra Tech, Inc. does not report the customer, stock and supplier day counts a cash cycle needs, so this section looks at its spending on assets instead. It spent $63.7 M on assets over the last 3 years. Averaged over those years that is 0.5% of FY25 revenue a year.

Working capital is the cash tied up between paying suppliers and getting paid. Debtor days: how long customers take to pay. Inventory days: how long stock sits. The cash cycle: the whole loop, in days of sales.

Nothing is estimated in place of the missing day counts, so no cash-cycle chart is drawn.

Spending on assets: $63.7 M over the last 3 years.

In short: the cash is going into new capacity, not getting stuck in the daily cycle. The question is whether the new capacity earns.

Tetra Tech, Inc.'s P/E is 24.6×, near the low end of its own history: it has been lower only 17% of the time. Its usual P/E (the middle reading) is 30.7×, over 4.6 years of weekly prices. This compares the share price with the company’s own past. It does not say what the business is worth.

P/E is the share price divided by a year's profit per share: how many dollars the market pays for each dollar of yearly profit.

Keep one thing in mind: margins are the best this company has ever reported. A multiple that looks low against its own past can mislead when profit is at a record. If margins fall back, today's multiple is higher than it looks.
