Sterling Wilson Solar delivered strong operational performance in FY26: revenue ₹7,548 crore, record unexecuted order book ₹11,813 crore, domestic order inflow +30% YoY, and Q4 PAT ₹142 crore. The headline FY26 net loss of ₹296 crore is almost entirely due to ₹611 crore in exceptional items (US litigation legacy costs) — the core India solar EPC business is profitable and growing. FY27 guided at +15% revenue and 8-10% gross margins. Good sentiment, medium confidence (US litigation uncertainty, Q4 revenue muted, Reliance order unclear).

What Drove the Results
- Unexecuted order book ₹11,813 crore — record visibility: At 1.6x FY26 annual revenue, the order book provides the strongest forward revenue visibility in the company's history. This record book reflects India's solar buildout accelerating: SWSOLAR won ₹10,062 crore of new orders in FY26 (domestic +30%). If FY27 order inflow matches FY26, the backlog will continue compounding.
- Domestic EPC ₹5,836 crore — India is the growth engine: The domestic India solar EPC business grew to ₹5,836 crore vs. international ₹1,444 crore — confirming SWSOLAR's successful pivot from international-heavy (pre-2022) to India-focused. International projects brought legacy litigation; domestic India projects have cleaner risk profiles and faster payment cycles.
- Q4 PAT ₹142 crore — operational profitability is real: Despite the FY26 annual net loss, Q4 FY26 PAT of ₹142 crore confirms the core EPC business is generating operating profit. The loss is entirely from exceptional items — not operating deterioration.
- US litigation exceptional ₹611 crore — painful but finite: Legacy US project disputes from pre-2020 international expansion have now resulted in ₹611 crore of cash costs in FY26. Management provided no specific estimate of remaining liability — this uncertainty is the key risk. However, each passing quarter of resolution reduces the overhang.
- FY27 gross margin target 8-10% — margin recovery path: SWSOLAR's gross margins have been under pressure from commodity price volatility and working capital constraints. The 8-10% guidance signals confidence that the India project mix (better pricing, shorter cycles) and improved cost management will restore margins to the profitable range.
What Management Said
Management was confident on the order book and India business but cautious on several fronts. On order book: "₹11,813 crore unexecuted — this is the strongest visibility we have ever had. Domestic order inflow grew 30%+ YoY." On FY27: "15% revenue growth with 8-10% gross margins — this is our guidance. We expect the India solar market to remain strong with 500 GW 2030 target." On US litigation: "We cannot give a specific quantum for remaining liability — these are active cases. We are working to resolve them." On Reliance order: "We cannot provide specifics at this time." On Q4 revenue: "Q4 was muted — geopolitical uncertainty caused some ordering delays. This is a timing issue, not a structural slowdown." On module prices: "Chinese production cuts and export tax removal are causing PV module price changes — we are monitoring closely."
Key Tailwinds and Risks
Tailwinds:
- India 500 GW renewable target by 2030 — multi-year solar buildout
- Domestic order inflow +30% YoY to ₹10,062 crore — market share holding
- Record unexecuted order book ₹11,813 crore — 1.6x revenue coverage
- O&M (Operations & Maintenance) business growing — annuity revenue building
- India focus reducing international project risk profile
Risks:
- US litigation ongoing — quantum of remaining liability uncertain
- Q4 revenue muted (₹1,946 crore) — FY27 execution needs acceleration from Q1
- PV module price volatility (Chinese production cuts, export policy) — procurement cost risk
- Reliance New Energy order status uncertain — large potential order with unclear timeline
- Nigeria and other international projects slow — capital locked in slow-paying markets

Frequently Asked Questions
What was Sterling Wilson Solar's FY26 revenue and why was there a net loss? Sterling Wilson Solar reported FY26 revenue of ₹7,548 crore. The FY26 annual net loss of ₹296 crore was almost entirely due to ₹611 crore in exceptional items — legal costs and provisions related to legacy US international project litigation. Excluding these exceptional items, the core India solar EPC business was operationally profitable (Q4 PAT of ₹142 crore confirms this).
What is SWSOLAR's unexecuted order book and what does it mean? SWSOLAR's unexecuted order book stands at ₹11,813 crore — a record high and 1.6x the company's FY26 annual revenue. An unexecuted order book represents contracted projects where work has not yet been completed and revenue has not yet been recognized. This provides forward revenue visibility: if SWSOLAR executes its backlog at current rates, FY27 revenue growth of 15%+ is underpinned by existing contracts.
What is the US litigation risk for Sterling Wilson Solar? Sterling Wilson Solar has legacy litigation from international solar EPC projects executed in the US before 2020. In FY26, ₹611 crore in exceptional items were recognized for legal costs and settlements. Management has not provided a specific estimate of remaining liability — this uncertainty is the key risk. As these cases are resolved (favorably or through settlement), the exceptional item burden will reduce. The core India business is unaffected by the US litigation.
