About Companhia de Saneamento do Paraná - SANEPAR

Companhia de Saneamento do Paraná, SANEPAR, provides water supply, sewage collection and treatment services primarily in the state of Paraná, Brazil.

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

• The aggressive BRL 11.8 billion 2025 to 2029 CapEx cycle for universalization and environmental compliance may lock SANEPAR into a high investment regime just as demand growth slows due to demographic maturity and efficiency gains. This could pressure future free cash flow and limit upside to earnings.
• The push toward 100 percent water service and 90 percent sewage coverage, with already high current levels in Paraná, reduces remaining room for organic volume expansion. Future top line growth could increasingly depend on tariff decisions and expansion into riskier new geographies, putting revenue growth at risk.
• The rapid digitalization agenda through Sanepar 5.0, including smart operations, data platforms, and cybersecurity, requires significant upfront and ongoing technology spend and specialized labor. This could erode operating leverage and compress EBITDA margins if efficiency gains do not fully materialize.
• Rising complexity in sludge treatment, circular economy projects, biogas and energy co-generation, and solid waste handling exposes SANEPAR to execution risk, higher regulatory and environmental compliance costs, and potential underperforming new-business lines, weighing on net margins.
• Expansion beyond Paraná via PPPs, auctions, and international technical cooperation may divert management focus into unfamiliar regulatory and political environments. This increases the probability of mispriced concessions or delayed paybacks, which could dilute returns on invested capital and depress long term earnings growth.

Assumptions

This narrative explores a more pessimistic perspective on Companhia de Saneamento do Paraná - SANEPAR compared to the consensus, based on a Fair Value that aligns with the bearish cohort of analysts. How have these above catalysts been quantified?

• The bearish analysts are assuming Companhia de Saneamento do Paraná - SANEPAR's revenue will grow by 5.3% annually over the next 3 years.
• The bearish analysts assume that profit margins will shrink from 30.1% today to 11.9% in 3 years time.
• The bearish analysts expect earnings to reach R$982.6 million (and earnings per share of R$1.76) by about December 2028, down from R$2.1 billion today. However, there is some disagreement amongst the analysts with the more bullish ones expecting earnings as high as R$1.6 billion.
• In order for the above numbers to justify the price target of the more bearish analyst cohort, the company would need to trade at a PE ratio of 15.4x on those 2028 earnings, up from 5.2x today. This future PE is greater than the current PE for the BR Water Utilities industry at 12.0x.
• The bearish 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 18.39%, as per the Simply Wall St company report.

Risks

What could happen that would invalidate this narrative?

• The company is executing a BRL 11.8 billion 2025 to 2029 investment cycle with over 2,300 projects aimed at completing water and sewage universalization in Paraná and strengthening environmental compliance. If delivered on time and on budget, these assets can underpin stable, regulated growth in connections and volumes, supporting long term revenue and earnings rather than compressing them.
• EBITDA margins of 41.5% year to date, net margin of 32.3% and leverage of only 0.5 times EBITDA after strong cash inflows give Sanepar substantial financial flexibility to absorb temporary cost spikes and provisions. If this conservative balance sheet is maintained, it reduces downside risk to net margins and earnings.
• The shift to the free energy market, digital optimization of networks and active loss reduction programs using advanced technologies such as hydraulic modelling, AI leak detection and automation have already produced sizeable energy savings. If scaled successfully, these structural efficiency gains can offset cost inflation and help sustain or improve operating margins and free cash flow.
• Innovation and new business initiatives in biogas, sludge drying, co processing, circular economy projects and PPP or international expansion create optionality for incremental, higher margin revenue streams over time. If these platforms mature, they can diversify the top line and support structural earnings growth beyond the core regulated tariff base.

Valuation

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

• The assumed bearish price target for Companhia de Saneamento do Paraná - SANEPAR is R$30.2, which represents up to two standard deviations below the consensus price target of R$38.26. This valuation is based on what can be assumed as the expectations of Companhia de Saneamento do Paraná - SANEPAR's future earnings growth, profit margins and other risk factors from analysts on the more bearish end of the spectrum.
  
• However, there is a degree of disagreement amongst analysts, with the most bullish reporting a price target of R$45.9, and the most bearish reporting a price target of just R$30.2.
  
• In order for you to agree with the more bearish analyst cohort, you'd need to believe that by 2028, revenues will be R$8.3 billion, earnings will come to R$982.6 million, and it would be trading on a PE ratio of 15.4x, assuming you use a discount rate of 18.4%.
  
• Given the current share price of R$36.5, the analyst price target of R$30.2 is 20.9% lower.
  
• 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.
