Urbanization And Regulatory Reforms Will Drive Water Utility Expansion

Key Takeaways

• Expansion through customer growth, acquisitions, and favorable regulation is driving sustainable revenue and earnings growth while improving operational scale and efficiency.
  
• Ongoing investments in modernization and digitalization strengthen margins, stabilize earnings, and support reliable financial performance in a regulated environment.
  
• Rising costs, elevated debt, regulatory uncertainty, weather disruptions, and heavy infrastructure investments could constrain earnings growth and apply pressure to long-term returns.

Catalysts

Through its subsidiaries, provides water and wastewater services in the United States.

• Persistent population growth and urbanization across key U.S. states are fueling organic customer additions (e.g., 2% customer growth target and multiple acquisitions adding ~87,000 connections); this underpins long-term revenue growth as American Water expands its service footprint and taps into rising water demand.
  
• Heightened regulatory and societal focus on water quality and infrastructure modernization is accelerating rate case approvals and driving significant capital investment (e.g., $3.3 billion capital spend in 2025, requests for $111 million cumulative rate increases in CA by 2029); these factors enable predictable, above-inflation rate increases and support sustainable earnings expansion.
  
• Systematic execution of a robust acquisition strategy, including the recent Nexus Water Group deal and a strong pipeline of municipal and private system takeovers, is creating scale and operational leverage; this drives margin improvement through synergies and supports non-organic revenue growth.
  
• Favorable legislative and regulatory developments-such as full decoupling in California-are reducing volume risk and promoting affordability, further stabilizing revenues and enabling more reliable net margin performance.
  
• Ongoing investment in digitalization, maintenance, and operational efficiency (e.g., enhanced digital metering, automation) is expected to mitigate O&M cost increases and improve net margins, supporting steady EPS growth even as capital expenditures remain elevated.

American Water Works Company Future Earnings and Revenue Growth

Assumptions

• Analysts are assuming American Water Works Company's revenue will grow by 6.8% annually over the next 3 years.
• Analysts assume that profit margins will increase from 21.9% today to 22.8% in 3 years time.
• Analysts expect earnings to reach $1.4 billion (and earnings per share of $6.76) by about August 2028, up from $1.1 billion today.
• In order for the above numbers to justify the analysts price target, the company would need to trade at a PE ratio of 24.7x on those 2028 earnings, down from 25.6x today. This future PE is greater than the current PE for the US Water Utilities industry at 21.6x.
• Analysts expect the number of shares outstanding to grow by 0.12% per year for the next 3 years.
• To value all of this in today's terms, we will use a discount rate of 6.78%, as per the Simply Wall St company report.

American Water Works Company Future Earnings Per Share Growth

Risks

• Persistent rises in operating, maintenance, and technology costs (highlighted by significant O&M and depreciation increases this quarter) threaten net margin expansion, especially if inflationary pressures persist faster than revenue growth.
  
• Higher interest and financing expenses due to continued reliance on significant debt issuances ($1 billion planned for 2025; 58% net debt-to-capital ratio) could erode net earnings and put pressure on future financial flexibility if rates remain elevated.
  
• Success in achieving timely and adequate rate relief is increasingly dependent on regulatory approvals across multiple states, and delayed or denied rate cases-particularly in key markets like California or Pennsylvania-could constrain revenue growth and shareholder returns.
  
• Adverse weather patterns already resulted in negative year-over-year earnings impacts, and ongoing climate volatility (e.g., droughts, floods) may further disrupt operating costs and diminish volume-driven revenue.
  
• The need for continuous, multi-billion-dollar investments in aging infrastructure raises the risk that capital expenditures will outpace allowed rate base growth, potentially depressing future returns on equity and threatening long-term earnings growth.

Valuation

• The analysts have a consensus price target of $143.0 for American Water Works Company 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 $159.0, and the most bearish reporting a price target of just $116.0.
  
• In order for you to agree with the analyst's consensus, you'd need to believe that by 2028, revenues will be $6.0 billion, earnings will come to $1.4 billion, and it would be trading on a PE ratio of 24.7x, assuming you use a discount rate of 6.8%.
  
• Given the current share price of $141.91, the analyst price target of $143.0 is 0.8% higher. The relatively low difference between the current share price and the analyst consensus price target indicates that they believe on average, the company is fairly priced.
  
• 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.
