Cambi Navigates Growth and Challenges: Q4 Revenue Climbs as Margins Tighten
This analysis is based on the company's Q4 2025 earnings call and financial report.
OSLO – Cambi ASA (FRA: 3W7), a leader in thermal hydrolysis solutions for sludge and waste management, closed 2025 with a quarter of contrasting signals. The company announced solid revenue growth and a healthy order intake during its fourth-quarter earnings call, pointing to strong market demand for its sustainable technology. However, these gains were partially offset by a noticeable squeeze on gross margins and a significant rise in operating expenses, painting a picture of a company expanding in a competitive and cost-sensitive environment.
CEO Per Lillebo struck an optimistic tone regarding core operations, detailing several key projects. He highlighted a new "indense" system for German utility Gelsenwasser, designed to increase wastewater plant capacity by up to 30% through a prefabricated, easy-to-install solution. Lillebo also discussed the company's low-heat chemical hydrolysis system, branded as "Pondus," which is gaining traction with smaller municipalities due to its lower capital expenditure and benefits in biogas production.
Yet, the financial details revealed underlying pressures. Acting CFO Per Olav Collin explained that a NOK 14 million quarter-on-quarter increase in payroll expenses was driven largely by bonus provisions and the consolidation of CNP Cycles. Furthermore, the company is still absorbing residual costs from its discontinued soil retail segment, though these are expected to decline through 2026.
Strategic moves were a focal point. The conversion of an intercompany loan to equity in subsidiary Gronn Vekst was framed as essential to bolster its balance sheet for public tenders. Looking ahead, Lillebo outlined a plan to return Gronn Vekst to full profitability by 2026 and explore international avenues, emphasizing its role as a complementary business that handles sludge to produce soil and fertilizer.
The company also sees a recurring revenue stream in modernization projects, such as upgrading older instrumentation at client sites, and in flexible leasing models. A notable example is a new leasing agreement with Thames Water in the UK, which Cambi hopes will lead to future opportunities.
Market Voices: Analysts and Observers Weigh In
Erik Johansen, Sustainability Fund Manager: "Cambi's technology is precisely what the circular economy needs. The margin pressure is a short-term growing pain. Their order book and projects like the one with Gelsenwasser prove the long-term demand is real."
Maria Chen, Industrial Analyst at Nordea Markets: "The revenue growth is commendable, but the margin erosion and cost increases cannot be ignored. Investors will want to see a clear path to operational leverage. The success of the Gronn Vekst turnaround will be a critical indicator of management's execution capability."
David Krogh, Independent Environmental Blogger: "Another quarter of 'growth' that doesn't translate to bottom-line strength. They're talking about international expansion while still nursing a loss-making subsidiary? The lease deal with Thames Water sounds like they're taking on a problematic site. This feels more like scrambling than strategic growth."
Anika Sharma, VP of Engineering at a European Water Utility: "From an engineering perspective, Cambi's push to modernize instrumentation is a smart move. Replacing legacy radioactive sources with modern flow meters reduces long-term operational headaches for operators like us, making their overall offering more attractive."
