European Regulations Will Accelerate Energy Efficient Biosolids Solutions

Key Takeaways

• Tighter regulations and emerging contaminants are increasing demand for Cambi's advanced, energy-efficient biosolids solutions, positioning the company for long-term growth and recurring revenues.
  
• Expansion into new markets and ongoing innovation are strengthening Cambi's margin profile, premium pricing power, and competitive advantage.
  
• Revenue and margin growth face risks from order backlog decline, unfavorable project mix, regulatory uncertainty, competitive pressures, and heavy reliance on public infrastructure funding cycles.

Catalysts

About Cambi

Provides thermal hydrolysis solutions for sewage sludge and organic waste management in Europe, the Americas, Asia, Africa, and Oceania.

What are the underlying business or industry changes driving this perspective?

• The increasing regulatory focus on energy neutrality and quaternary treatment in Europe (e.g., the Urban Wastewater Directive) is expected to drive higher demand for advanced and energy-efficient biosolids solutions like Cambi's new THP Model E, likely boosting long-term revenue growth and supporting gross margin expansion as utilities seek compliant, sustainable technologies.
  
• Rising restrictions on land application of biosolids due to emerging contaminants (microplastics, PFAS) are pushing utilities towards flexible, future-proof thermal treatment platforms, such as Cambi's, which directly benefits long-term revenue visibility and positions Cambi's solutions as a "no regret" investment for risk-averse utilities.
  
• Cambi's growing installed base and maintenance needs, along with strong demand for performance upgrades and spare parts, are expanding predictable, higher-margin service revenues, supporting margin improvement and more stable earnings over time.
  
• Geographic expansion and increased regulatory stringency in large markets (notably Germany after the CNP CYCLES acquisition, and increased interest from populous developing cities) are opening significant new sales pipelines and service opportunities, offering both revenue diversification and long-term earnings growth potential.
  
• Continued investments in innovation and energy efficiency (e.g., 30% lower energy use at Lilleström) support Cambi's ability to charge premium prices, maintain technological leadership, and safeguard net margins-especially as energy costs and emissions regulation become more central to purchasing decisions.

Cambi Future Earnings and Revenue Growth

Assumptions

How have these above catalysts been quantified?

• Analysts are assuming Cambi's revenue will grow by 13.7% annually over the next 3 years.
• Analysts assume that profit margins will increase from 15.2% today to 18.4% in 3 years time.
• Analysts expect earnings to reach NOK 291.9 million (and earnings per share of NOK 1.86) by about September 2028, up from NOK 164.2 million today. The analysts are largely in agreement about this estimate.
• In order for the above numbers to justify the analysts price target, the company would need to trade at a PE ratio of 16.2x on those 2028 earnings, down from 18.2x today. This future PE is lower than the current PE for the NO Machinery industry at 27.9x.
• Analysts expect the number of shares outstanding to remain consistent over the next 3 years.
• To value all of this in today's terms, we will use a discount rate of 7.17%, as per the Simply Wall St company report.

Cambi Future Earnings Per Share Growth

Risks

What could happen that would invalidate this narrative?

• The order backlog has declined significantly year-on-year (from nearly NOK 1.5 billion to NOK 938 million), and Cambi acknowledged that new contract awards are needed to maintain current activity and profitability. If the company fails to secure substantial new orders, there is a risk of a revenue dip in 2026, negatively impacting both revenue growth and earnings visibility.
  
• Gross margins are under pressure due to a less favorable project mix (higher share of extended scope contracts with lower margins) and FX impacts. Ongoing high operational expenses from previous organizational investments and inflation risk in materials and skilled labor may continue to weigh on net margins and earnings.
  
• Heightened regulatory uncertainty around emerging contaminants (notably PFAS and microplastics) and restrictions on land application of biosolids may cause delays in utility decision-making and project awards, creating lumpiness in order intake and increasing the risk of revenue volatility in the long term, especially in developed markets.
  
• Intense competitive pressure in core markets, particularly Germany and the broader EU (where Cambi is expanding via acquisition and stricter regulations exist), may limit market share gains or force price competition, impacting profitability and posing risk to the planned synergies and revenue from newly acquired entities like CNP CYCLES.
  
• Cambi's dependence on municipal/government capex cycles and infrastructure funding exposes it to macroeconomic downturns and policy shifts; any budget tightening or changes in wastewater management priorities (including increased adoption of decentralized or alternative treatment technologies) could reduce demand for Cambi's high-capital-intensity solutions, constraining long-term revenue growth.

Valuation

How have all the factors above been brought together to estimate a fair value?

• The analysts have a consensus price target of NOK24.0 for Cambi based on their expectations of its future earnings growth, profit margins and other risk factors.
• In order for you to agree with the analyst's consensus, you'd need to believe that by 2028, revenues will be NOK1.6 billion, earnings will come to NOK291.9 million, and it would be trading on a PE ratio of 16.2x, assuming you use a discount rate of 7.2%.
• Given the current share price of NOK18.7, the analyst price target of NOK24.0 is 22.1% 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.
