Water Sustainability And Digital Automation Will Generate Lasting Impact

Key Takeaways

• Focus on high-value, tech-driven services and recurring revenue streams is boosting margins and earnings stability.
  
• Strong financial health and strategic investments support long-term shareholder value and growth potential.
  
• Revenue concentration risks have increased due to lost government contracts, non-recurring disaster work, sluggish commercial growth, and shifting U.S. federal budget priorities.

Catalysts

Provides consulting and engineering services that focuses on water, environment, and sustainable infrastructure.

• Increased global investment and regulatory pressure around climate adaptation, sustainability, and infrastructure resilience are driving continued growth in Tetra Tech's water, environmental, and disaster response businesses, with state and local water programs seeing high-teens to 20% growth-supporting robust, recurring revenue growth potential.
  
• Ongoing expansion of advanced digital automation and analytics offerings, catalyzed by rising adoption of AI and recent strategic acquisitions, positions Tetra Tech for higher-margin, tech-driven consulting services and recurring revenue streams, supporting long-term net margin and earnings growth.
  
• Government stimulus and large new federal contracts-such as major allocations in defense facilities, Coast Guard, and air traffic control system upgrades-are expanding Tetra Tech's U.S. public sector pipeline, reducing reliance on more volatile commercial segments and enhancing earnings stability.
  
• Execution of a strategic shift away from lower-margin USAID and legacy work toward complex, higher-value projects has already resulted in record high company margins, with management targeting ongoing annual margin expansion of 50+ basis points, suggesting further earnings leverage ahead.
  
• Strengthened balance sheet, robust cash flow generation, and an active share repurchase program create additional upside for EPS growth, while industry-leading DSO metrics and reduced leverage support both organic investment and accretive M&A, underpinning long-term shareholder value creation.

Tetra Tech Future Earnings and Revenue Growth

Assumptions

• Analysts are assuming Tetra Tech's revenue will decrease by 0.8% annually over the next 3 years.
• Analysts assume that profit margins will increase from 4.7% today to 11.9% in 3 years time.
• Analysts expect earnings to reach $559.6 million (and earnings per share of $1.78) by about September 2028, up from $216.1 million today.
• In order for the above numbers to justify the analysts price target, the company would need to trade at a PE ratio of 23.7x on those 2028 earnings, down from 42.7x today. This future PE is lower than the current PE for the US Commercial Services industry at 25.7x.
• Analysts expect the number of shares outstanding to decline by 1.86% per year for the next 3 years.
• To value all of this in today's terms, we will use a discount rate of 7.03%, as per the Simply Wall St company report.

Tetra Tech Future Earnings Per Share Growth

Risks

• The elimination of USAID as a client and the wind down of Department of State work, which previously contributed significant revenue, exposes Tetra Tech to revenue concentration in other areas and creates uncertainty about replacing lost revenue from these lapsed government contracts in future periods, directly impacting top-line growth and backlog visibility.
  
• The significant uplift in recent quarters' margins and revenues was driven by exceptional, episodic disaster response work (e.g., Southern California fires), which is non-recurring in nature and expected to contribute minimally in coming quarters, increasing the risk of margin compression and inconsistent earnings performance.
  
• Management noted a shift in U.S. federal government contracting cadence to a "book and burn" approach with delayed task order issuance, coupled with governmental staffing reductions and early retirements in contracting offices; these trends could result in persistent backlog stagnation or declines and shortened revenue visibility, therefore impacting long-term revenue predictability and backlog-driven valuation.
  
• International and commercial segments remain sluggish, with revenue declines in U.S. commercial (down 4% YoY, largely due to reduced renewable energy work) and flat international performance (with ongoing Australian weakness), highlighting region
• and sector-based risk to broad-based revenue and exacerbating reliance on U.S. government-related growth.
  
• Recent budget shifts, such as increased U.S. federal funding for defense, Coast Guard, and air traffic control, come at the expense of renewable energy and possibly future infrastructure/transportation projects, creating a risk that government fiscal priorities could continue to shift away from Tetra Tech's traditional or growth areas (e.g., renewables, non-defense infrastructure), driving cyclicality and margin volatility in core services over time.

Valuation

• The analysts have a consensus price target of $43.6 for Tetra Tech based on their expectations of its future earnings growth, profit margins and other risk factors. However, there is a degree of disagreement amongst analysts, with the most bullish reporting a price target of $48.0, and the most bearish reporting a price target of just $40.0.
• In order for you to agree with the analyst's consensus, you'd need to believe that by 2028, revenues will be $4.7 billion, earnings will come to $559.6 million, and it would be trading on a PE ratio of 23.7x, assuming you use a discount rate of 7.0%.
• Given the current share price of $35.1, the analyst price target of $43.6 is 19.5% higher.
• We always encourage you to reach your own conclusions though. So sense check these analyst numbers against your own assumptions and expectations based on your understanding of the business and what you believe is probable.
