They were originally part of the Shapoorji Pallonji Group, but Reliance New Energy now holds a 32.5% stake, making it the dominant promoter.
SWSOLAR serves independent power producers, developers, and equity funds, leveraging end-to-end capabilities in project design, procurement, construction, commissioning, and asset management (Sterling and Wilson Renewable Energy Limited, 2022).
Detailed Ownership Structure: Strategic Backing:
Historical Context: Rooted in the Shapoorji Pallonji Group, a 160-year-old Indian conglomerate with a strong infrastructure legacy.
Current Ownership: Reliance New Energy Ltd (a Reliance Industries subsidiary) holds a 32.5% stake (acquired 2022), providing strategic and financial synergies. Shapoorji Pallonji retains a 6.9% stake, with public and institutional investors holding the rest.
Promoter Holding: 45.7%, down from 76.7% over three years due to dilution, offset by Reliance’s entry (Screener, 2025).
Waaree Group Clarification: SWSOLAR has no ownership or operational ties with the Waaree Group. A 2021 merger involving Sterling & Wilson–Waaree Pvt Ltd was a one-time structural event with no ongoing linkage.
Q1 FY26 Financial Performance: Strong Turnaroun:
SWSOLAR’s Q1 FY26 results (April–June 2025) reflect robust growth:
Revenue: ₹1,761.63 crore, up 92.5% YoY from ₹915.06 crore (Q1 FY25), though down 30.1% QoQ from ₹2,519.11 crore (Q4 FY25) due to seasonal project cycles (Business Standard, 2025).
Gross Profit: ₹205 crore, up 101% YoY, with gross margins at 11.7% (Business Standard, 2025).
EBITDA: ₹102 crore, up 176% YoY, with margins at 5.8%, driven by cost optimization (SolarQuarter, 2025).
Net Profit (PAT): ₹31.97 crore, up 663% YoY from ₹4.19 crore, marking consecutive profitable quarters (Business Standard, 2025).
Order Inflow: ₹2,170 crore (₹1,154 crore international, ₹1,016 crore domestic). Unexecuted order book: ₹9,396 crore (July 18, 2025), ~1.5x FY25 revenue (SolarQuarter, 2025).
Debt and Working Capital: Net debt reduced 90% to ₹97 crore (June 2024); working capital days improved from 145 to 47.2 (Saur Energy, 2024).
Analysis: YoY growth reflects SWSOLAR’s ability to capitalize on India’s solar boom and global demand. The QoQ dip is typical, with H2 contributing 60–65% of annual revenue. Margin expansion and debt reduction signal financial strength (SolarQuarter, 2025).
Policy Tailwinds: Structural Growth Drivers:
India’s renewable energy policies fuel SWSOLAR’s growth:
🧨PLI Scheme: Enhances domestic module supply, reducing EPC input costs.
🧨Import Restrictions: Curbs on Chinese solar equipment boost domestic competitiveness.
🧨500 GW Target: India’s goal of 500 GW non-fossil fuel capacity by 2030 drives EPC and O&M demand (Financial Express, 2025).
🧨PM Surya Ghar Muft Bijli Yojana: Subsidies for rooftop solar fuel domestic pipelines.
🧨State Tenders: Strong presence in Gujarat (e.g., 225 MW PV project) and Rajasthan ensures order flow (Tickertape, 2025).
Globally, SWSOLAR benefits from ESG investment flows and demand in the Middle East, Africa, and Europe.
The US Anti-Dumping Duty Concerns:
Context: On July 18, 2025, SWSOLAR shares fell 4% after U.S. manufacturers filed trade petitions accusing Indian firms of dumping subsidized solar modules, following high duties on Southeast Asian suppliers (e.g., 3,521% on Cambodia) (Equitymaster, 2025).
Rebuttal:
Limited U.S. Exposure: The U.S. contributes ~5–10% of revenue, with India and other regions driving the **₹9,396 crore order book (SolarQuarter, 2025).
Geographic Diversification: Orders like a $1.5 billion Nigeria MoU and projects in Europe and Latin America reduce U.S. reliance (Saur Energy, 2024).
BESS Pivot: Expansion into battery energy storage systems, less affected by module duties, diversifies revenue (Equitymaster, 2025).
Market Opportunity: U.S. duties on Southeast Asia create a supply gap, positioning SWSOLAR as a non-Chinese supplier with potential for long-term contracts.
Management Strategy: SWSOLAR is exploring legal and diplomatic remedies, leveraging Reliance’s influence and India’s trade agreements (SolarQuarter, 2025).
Outlook: Short-term margin pressure is possible, but SWSOLAR’s diversified portfolio and domestic focus mitigate risks, with opportunities in non-U.S. markets.
Brokerage Targets:
🧨Nuvama (July 2023): ‘Buy’ with ₹454 target (~51% upside) (Business Today, 2023).
🧨MNCL (February 2024): ₹800 target (~166% upside), citing PSU and international orders (INDmoney, 2025).
🧨INDmoney (February 2025): ₹420 target (~40% upside), based on financial recovery (INDmoney, 2025).
Projections:
Order Book: ₹10,000–12,000 crore by FY26 end (Tickertape, 2025).
Revenue: 20–30% YoY growth in FY26, with H2 driving ~60–65% of revenue (SolarQuarter, 2025).
EBITDA Margins: 6–8% by FY26, supported by cost efficiencies (Business Standard, 2025).
PAT: ₹150–200 crore in FY26, driven by execution and margins (SolarQuarter, 2025).
Strategic Advantages:
Reliance Synergies: Access to Reliance’s module sourcing and financing for projects like its 20 GW solar rollout (Business Today, 2023).
Global Scale: 19.4 GWp EPC portfolio across 28 countries (Sterling and Wilson Renewable Energy Limited, 2022).
Execution Expertise: Recent 225 MW Gujarat project** win (Tickertape, 2025).
Financial Turnaround: 90% debt reduction to ₹97 crore, working capital at 47.2 days (Saur Energy, 2024).
Institutional Support: Investors include Vanguard Group, HSBC AMC, and 17 mutual fund schemes (INDmoney, 2025).
Key Risks:
The US Anti-Dumping Duties: Potential margin pressure, mitigated by diversification.
Thin Margins: ~5–6% margins vulnerable to commodity and forex risks.
Execution Delays: EPC project delays may impact revenue.
High Valuation: P/E of ~64.0 requires sustained earnings growth.
Conclusion: A High-Conviction Solar Play:
At ₹300.50, SWSOLAR offers exposure to India’s renewable energy megatrend, backed by Reliance New Energy (32.5% stake) and a ₹9,396 crore order book. Its global EPC leadership and alignment with India’s 500 GW target by 2030 drive growth. Brokerage targets (₹420–₹800) reflect optimism, with 20–30% revenue growth projected for FY26. The U.S. anti-dumping issue is a short-term headwind, mitigated by diversified markets and BESS focus. High valuations require patience, ideal for long-term, risk-tolerant investors.
