Tetra Tech heads into its fiscal fourth-quarter report with something it has not had in a while: momentum that the market is starting to believe. After a bruising year spent absorbing the loss of USAID work, the engineering and consulting firm told investors last quarter that backlog had turned higher year over year for the first time in several quarters. It also raised full-year guidance for the fourth straight time. The November 11 release, due after the close, is the first chance to see whether that turn was a genuine shift or a single good quarter.
The Street expects earnings of $0.47 a share on revenue of about $1.14 billion. That sits comfortably within management's guidance of $0.45 to $0.48 on revenue of $1.12 billion to $1.17 billion. On earnings, consensus leans toward the upper half of the range. On revenue, it is a touch below the midpoint. The year-over-year math looks odd at first glance: revenue is projected to fall roughly 14%, while earnings per share are expected to grow about 4% from $0.45. That gap is the story of the past year. Low-margin USAID and one-time disaster work have rolled off, and margins on the remaining business have improved. Management guided to about 70 basis points of margin expansion for the year, well ahead of its 50-basis-point long-term target. Holding segment margins near the third quarter's 17.5% in government services and 15.1% in commercial and international would keep that story intact.
Backlog is the number that matters most. It climbed 8% sequentially in the second quarter and another 5% in the third, to just under $4.5 billion, after sitting flat around $4.14 billion a year ago. A third consecutive increase would show that the new work is broad based. That work includes roughly $300 million of Army Corps capacity, the Dayton PFAS treatment system, FAA airspace modernization, and data center and power transmission orders. A flat or declining figure would revive the worry that federal contracting friction is still capping growth. Management said that friction, tied to staff cuts and shorter task-order durations, is making procurement slower and choppier. The third quarter's double-digit growth in both U.S. federal and international work offered encouragement, and repeating it would help.
The soft spots deserve equal scrutiny. U.S. commercial grew just 1% last quarter, weighed down by the cancellation of Atlantic offshore wind programs. Management is counting on power, mining and data center demand to fill that hole, so any acceleration there would be meaningful. State and local growth guidance was already trimmed to 5% to 10%, with federal flood-protection co-funding withheld. Ukraine-related State Department revenue, roughly $66 million a quarter, adds political exposure that could swing the outlook.
The market has already rewarded the improving narrative. Shares have gained about 13% since the last report, beating the S&P 500 by roughly 11 percentage points. At $39.57, the stock trades about 20% above its 200-day moving average and sits within a hair of its post-earnings high of $39.80, effectively testing a breakout. Sentiment has improved sharply, with the bearish reading easing to 22.6% from 47.3% a quarter ago, though it remains on the negative side. That combination suggests skepticism is fading but has not disappeared, and an in-line print may no longer be enough to push the stock through resistance.
The bar, then, is less about hitting $0.47 and more about what comes with it. Four straight raises have conditioned investors to expect upside. A fourth-quarter report with guidance-topping results, another step up in backlog and strong cash flow would validate the inflection thesis. Those cash flow measures include year-to-date operating cash flow of $467 million, sustained buybacks and leverage below 0.9 times. Any early commentary on fiscal 2027 that points to net revenue growth would strengthen it further. If backlog stalls or commercial demand stays flat, the recent rally may look like it priced in a recovery that has not fully arrived.
