Hybrid Solar And Storage Platforms Will Drive Powerful Long Term Upside Potential

About Grenergy Renovables

Grenergy Renovables develops, finances and operates solar PV and battery energy storage projects across Europe and the Americas.

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

• Rapid scale up of the Oasis of Atacama and Central Oasis hybrid PV plus storage platforms in Chile, where large, already contracted and near-COD projects like Elena and Gabriela are expected to transform the earnings base through high merchant prices, capacity payments and PPA-backed cash flows, materially lifting group revenue and EBITDA.
• Acceleration of the Greenbox stand-alone storage platform in six European markets, with 8 gigawatt hours already in advanced development and flagship projects such as Oviedo moving to construction, positioning Grenergy to monetize multiple revenue stacks and improve group net margins as returns in Spain and Germany trend to double digits.
• Structural shift in power systems toward high solar penetration and the need for flexibility, which strongly favors Grenergy’s combined PV and BESS model and deep pipeline of 75 gigawatt hours, supporting sustained project deployment, recurring asset rotation gains and growing earnings visibility.
• Upside from upcoming tolling agreements and PPAs with investment-grade counterparties in Europe and Latin America, including Chile, Spain and Germany, which should de-risk cash flows, compress financing costs and enhance net profit through higher, more stable realized prices.
• Expanding optionality in high-growth markets such as the United States and data-center-driven demand in Chile and Europe, where safe-harbored U.S. projects, attractive ITC levels and potential long-term offtake for 24/7 low-cost power could drive incremental high-margin revenue and asset rotation gains beyond the current business plan.

Assumptions

This narrative explores a more optimistic perspective on Grenergy Renovables compared to the consensus, based on a Fair Value that aligns with the bullish cohort of analysts. How have these above catalysts been quantified?

• The bullish analysts are assuming Grenergy Renovables's revenue will grow by 11.7% annually over the next 3 years.
• The bullish analysts assume that profit margins will increase from 9.5% today to 19.1% in 3 years time.
• The bullish analysts expect earnings to reach €278.7 million (and earnings per share of €9.76) by about December 2028, up from €98.9 million today. However, there is some disagreement amongst the analysts with the more bearish ones expecting earnings as low as €108.3 million.
• In order for the above numbers to justify the price target of the more bullish analyst cohort, the company would need to trade at a PE ratio of 12.5x on those 2028 earnings, down from 23.7x today. This future PE is lower than the current PE for the ES Renewable Energy industry at 19.8x.
• The bullish analysts expect the number of shares outstanding to decline by 2.15% per year for the next 3 years.
• To value all of this in today's terms, we will use a discount rate of 9.81%, as per the Simply Wall St company report.

Risks

What could happen that would invalidate this narrative?

• The long term asset rotation model depends on a liquid M&A market and buyers willing to pay around 1.6 times enterprise value to invested capital. If demand for contracted renewables or BESS platforms weakens as rates stay higher for longer, or utilities and infrastructure funds pull back, Grenergy may have to sell assets at lower multiples or retain more projects on balance sheet. This would pressure capital recycling, slow growth and reduce earnings and asset rotation driven revenue.
• The business plan assumes sustained high returns on very large scale BESS and hybrid platforms such as Oasis of Atacama, Central Oasis and Greenbox. A prolonged fall in power price volatility, capacity payments that arrive later than expected or underdeliver, or weaker ancillary service markets in Europe and Chile would compress project IRRs below the expected high single digit to double digit range. This would weigh on net margins and the EBITDA uplift from new capacity.
• The company is committing around EUR 3.5 billion of CapEx between 2025 and 2027, with more than EUR 1 billion per year already in sight. If supply chain costs for batteries and grid connection rise again, key equipment is delayed or U.S. and European trade policies increase tariffs on components, project CapEx could overshoot assumptions and force repricing or cancellation of projects. This would undermine returns and lower future earnings versus current guidance such as the EUR 70 million to EUR 90 million EBITDA expected from Elena.
• Grenergy is rapidly expanding into multiple new and less mature markets such as Poland, Romania and the United States, while also scaling complex tolling agreements and PPAs with investment grade counterparties across continents. Execution missteps, regulatory changes in emerging storage markets or weaker than expected PPA pricing in places like Chile and the U.S. could leave parts of the 75 gigawatt hour pipeline locked into lower value contracts. This would reduce realized power prices and limit revenue growth and profitability.
• The strategy relies on maintaining relatively low leverage, with net debt to EBITDA expected to normalize quickly after asset sales. However, the current net debt of around EUR 1.047 billion and record CapEx of EUR 713 million in nine months increase exposure to any delay in disposals such as Gabriela or future Oasis phases. A period of tighter credit or weaker valuations at the time of rotation could leave leverage elevated for longer, raise financing costs and dilute net profit as interest expense absorbs a greater share of EBITDA.

Valuation

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

• The assumed bullish price target for Grenergy Renovables is €100.0, which represents up to two standard deviations above the consensus price target of €84.66. This valuation is based on what can be assumed as the expectations of Grenergy Renovables's future earnings growth, profit margins and other risk factors from analysts on the bullish end of the spectrum.
  
• However, there is a degree of disagreement amongst analysts, with the most bullish reporting a price target of €100.0, and the most bearish reporting a price target of just €72.0.
  
• In order for you to agree with the more bullish analyst cohort, you'd need to believe that by 2028, revenues will be €1.5 billion, earnings will come to €278.7 million, and it would be trading on a PE ratio of 12.5x, assuming you use a discount rate of 9.8%.
  
• Given the current share price of €83.5, the analyst price target of €100.0 is 16.5% 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.
