Growth thesis

Synergy Green Industries operates a foundry in Kolhapur producing large castings from 3 to 30 metric tonnes, serving wind turbine OEMs, gearbox makers, and non-wind sectors like mining and conventional power. The company counts six of the world's top fifteen wind OEMs among its customers, including Vestas, Nordex, and Siemens Gamesa, and sits in the upstream component supply chain for the global wind buildout. The Indian competitive landscape is narrow, with only a couple of meaningful domestic foundry rivals, while the company holds cost and logistics advantages over Chinese suppliers given the recent yuan appreciation against the rupee and US tariff rollback to 18%. FY26 PBDIT margin came in at 13.1%, but this reflects a year of expansion disruption and outsourced machining; management has guided a 300 basis point improvement for FY27, with a path to 18% plus margins in FY28.

The economics persist because of qualification cycles and customer stickiness. New product development with an existing OEM takes 6 to 8 months, while onboarding a new customer requires roughly two years, including audits and prototype approvals. The company has executed 12 new product developments in FY26 alone, embedding itself into OEM platforms like the Vestas 4 MW and Nordex 5 MW. The investment required for a new foundry of this scale, with customer approvals and serial production experience, would take 3 to 5 years to become competitive, providing a high entry barrier. Additionally, the company has an import substitution opportunity; for instance, it recently secured a L&T order for super thermal power plant casings previously imported, and received BHEL facility approval. The combination of long approval cycles, proven reliability across six major OEMs, and a cost base that is now 5 to 10% cheaper than China on landed cost in the US bolsters the durability of its niche.

The inflection is already underway. The foundry capacity has expanded from 30,000 to 45,000 tonnes, with the second automated line commissioned by March 2026, and utilization reached 66% in Q1 FY27, targeting 80% for the full year. The in-house machining facility of 20,000 tonnes is moving from development to serial production, with 50% utilization achieved in mid-2026 and stabilization expected by Q2 FY27. By the end of FY27, the business should deliver revenue of around 500 crores, a 33% increase over FY26, with PBDIT margins up 300 basis points to roughly 16%. Looking 18 to 24 months out, that is by the second half of FY28, the Vestas 4 MW contract signed for January to December 2027 will be in full serial production, adding 30 to 40% growth over historical export volumes. Nordex 5 MW serial production for the US market, Adani 3.3 MW platform ramping, and new conventional power revenue from L&T and BHEL of 20 to 25 crores annually from H2 FY27 will broaden the revenue base. With the 45,000 tonne foundry hitting 90% plus utilization and machining running at full tilt, revenue has the potential to reach 550 to 650 crores in FY28, while margins could push toward the 18% PBDIT guidance cited for that year. Land acquisition for the next phase, a greenfield expansion to 100,000 tonnes, is targeted by March 2027, with a 500 to 600 crore capex decision expected in Q2 to Q3 FY27, positioning the business for a further step change in capacity from FY29 onward.

Management's execution history is mixed but the forward trajectory is consistent. In November 2025, the company forecast 20% revenue growth for FY26, but by February 2026 it revised that to around 5% growth due to project delays and production disruptions during the brownfield expansion, ending FY26 with 13.1% PBDIT margin. However, the company consistently guided FY27 revenue of 500 crores and 300 basis points margin expansion across the last three calls, and reiterated that guidance in August 2026 even after Q1 FY27 margins came in weak at 7% due to raw material inflation and electricity tariff changes. Management has delivered on capacity: the 45,000 tonne foundry and 20,000 tonne machining are operational, and the machining facility achieved 50% utilization by mid-2026. The capital structure remains manageable, with debt around 165 crores and an expected closing debt of 175 to 180 crores by FY27, keeping the debt-to-equity below 1.5. The next capex of 500 to 600 crores is planned to be funded through internal accruals, debt, and equity, though specifics are pending finalization in Q2 to Q3 FY27. The company has not raised equity beyond a small amount for the current expansion, and management has committed to early repayment of term loans once margins hit 16 to 18%.

The earnings path is quantifiable: FY27 revenue of 500 crores at a 16% PBDIT margin implies roughly 80 crores of PBDIT, nearly double the FY26 level. To achieve this, the company needs to recover the Q1 margin dip through raw material pass-through indexation, which typically lags by one quarter, and realize the operating leverage from higher utilization and in-house machining. The order book already exceeds 500 crores for FY27, with customer projections pointing to a potential of 650 to 700 crores, but management discounts this to the 500 crore guidance. The single most important watchpoint is capacity utilization: should the foundry fail to reach 80% for the year, or should machining stabilisation slip beyond Q2 FY27, the margin expansion will fall short. Another falsifier is customer concentration; Vestas historically contributed 40 to 48% of revenue, and although that is expected to fall to around 30% as Nordex, Envision, and Adani ramp, any delay in those ramps would reduce both revenue and margin. The tension between Q1 FY27's 7% PBDIT margin and the full-year 16% guidance is operational, not structural, because the cost inflation is recoverable with a lag and the company has a history of resolving quarter-level volatility. The kill shot would be a failure to land the greenfield land acquisition by March 2027, which would delay the next growth phase but not alter the current two-year earnings trajectory. Overall, the business 18 to 24 months out should be a larger, higher-margin foundry with a broader customer base, executing on a credible order book while preparing to double capacity.
