About Sterling and Wilson Renewable Energy

Sterling and Wilson Renewable Energy is an engineering, procurement and construction company focused on large scale solar and hybrid clean energy projects, along with associated operations and maintenance services.

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

• Although the domestic solar EPC pipeline in India remains robust with strong PSU and IPP ordering activity, any slowdown in tender finalization or tariff adoption for solar plus storage and hybrid projects could defer execution of the INR 9,287 crores order book and temper revenue growth in coming years.
• While the company is well placed to participate in emerging battery storage and hybrid solar projects, delays in tariff clarity and project structuring for these newer formats may cap the mix shift toward higher value contracts and limit any sustained improvement in blended EBITDA margins.
• Although the O&M portfolio of 9.1 gigawatts offers relatively stable, high margin cash flows, slower than expected conversion of internal EPC projects into long term O&M contracts and any slippage in third party O&M wins could constrain the targeted 20% to 23% O&M margins from translating into stronger consolidated net margins.
• Despite a stabilizing global module pricing environment that should support turnkey EPC competitiveness, a higher share of contracts that bundle module supply can structurally keep project level margins at the lower end of the guided 4% to 6% operational EBITDA range and weigh on overall earnings quality.
• While balance sheet clean up of legacy international projects and fresh term loans from development lenders improve near term liquidity, elevated net debt and any rating pressure after large write offs could increase funding costs and restrict working capital flexibility, limiting the ability to scale revenue without diluting profitability.

Assumptions

This narrative explores a more pessimistic perspective on Sterling and Wilson Renewable Energy 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 Sterling and Wilson Renewable Energy's revenue will grow by 12.5% annually over the next 3 years.
• The bearish analysts assume that profit margins will increase from -4.7% today to 6.3% in 3 years time.
• The bearish analysts expect earnings to reach ₹7.1 billion (and earnings per share of ₹30.33) by about December 2028, up from ₹-3.7 billion today. The analysts are largely in agreement about this estimate.
• 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 13.5x on those 2028 earnings, up from -13.5x today. This future PE is lower than the current PE for the IN Construction industry at 17.7x.
• The bearish analysts expect the number of shares outstanding to grow by 0.75% per year for the next 3 years.
• To value all of this in today's terms, we will use a discount rate of 16.18%, as per the Simply Wall St company report.

Risks

What could happen that would invalidate this narrative?

• Legacy international disputes and arbitration losses could signal deeper structural weaknesses in project selection and risk management, leading to further write-offs, erosion of net worth and sustained pressure on earnings and net margins over the long term.
• High reliance on bank funding and fresh term loans in the context of a weakened balance sheet raises the risk of credit rating downgrades and higher borrowing costs, which could constrain working capital, slow order execution and compress net margins and cash flow generation.
• Persistent delays and uncertainty in large projects such as the Nigeria order and the Reliance-linked pipeline may cause mismatch between headline order book and actual execution, resulting in slower revenue conversion, lumpier earnings and heightened downside risk to long-term revenue growth.
• An increasing share of turnkey EPC contracts that include module supply, where margins are structurally lower than balance of system projects, could cap operational EBITDA in the 4% to 6% range and limit improvement in consolidated net margins and return on equity even if topline continues to grow.
• Dependence on policy-driven segments like battery storage, hybrid and large PSU or IPP tenders, combined with potential delays in tariff adoption, auctions and regulatory clarity, could prolong tender finalization cycles and defer execution of the INR 9,287 crores order book, negatively impacting revenue visibility and long-term earnings growth.

Valuation

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

• The assumed bearish price target for Sterling and Wilson Renewable Energy is ₹255.0, which represents up to two standard deviations below the consensus price target of ₹320.5. This valuation is based on what can be assumed as the expectations of Sterling and Wilson Renewable Energy'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 ₹386.0, and the most bearish reporting a price target of just ₹255.0.
  
• In order for you to agree with the more bearish analyst cohort, you'd need to believe that by 2028, revenues will be ₹112.0 billion, earnings will come to ₹7.1 billion, and it would be trading on a PE ratio of 13.5x, assuming you use a discount rate of 16.2%.
  
• Given the current share price of ₹214.89, the analyst price target of ₹255.0 is 15.7% 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.
