Supreme Power Equipment is a transformer manufacturer whose economics depend on filling a new 9,000 MVA Kannur plant with higher-voltage power transformers while holding a PAT margin around 9-12%. The business sells power, distribution and inverter-duty transformers to state utilities, renewable developers and EPC contractors. At the Q2 FY27 call the order book was ₹565.80 crore, with power transformers about 78%, distribution 16-17% and inverter duty about 5%. Government orders were 27-28%. H1 FY27 total income was ₹135.57 crore, EBITDA ₹23.62 crore and PAT ₹13.65 crore, a 10.07% PAT margin. The thesis is not that demand is weak; it is that execution, qualification and working capital determine how much of the demand converts into revenue and cash.
The earnings path is now more ambitious. Management guides FY27 revenue at ₹300-350 crore, with H2 execution of ₹200-225 crore after ₹135.57 crore in H1. Customer requirement is ₹353 crore before March 2027 and ₹212 crore after March, so the H2 guidance is deliberately below the customer schedule. For FY28, management expects combined peak revenue of ₹550-600 crore, with ₹200-250 crore from the new plant and ₹70-80 crore from Unit 1. That is a sharp upgrade from the prior call, when FY28 was described as another ₹100 crore added to FY27. The FY27 guidance is explicit management guidance. The FY28 figure is also management guidance, but it is a peak-revenue target, not a committed annual revenue forecast, and it assumes the new plant reaches about 80% utilisation next year.
The operating mechanism is capacity utilisation. The Kannur plant was at 20-30% utilisation in H1 FY27, with 40-50% targeted by March 2027 and about 80% next year. Management said about ₹100-120 crore had been spent on the Kannur capacity. The old plant can contribute ₹70-80 crore annually; the new plant is expected to contribute ₹200-250 crore. If the ramp holds, incremental revenue carries the existing overhead base and supports the guided margin band. If the ramp slips, the fixed cost of the new plant and the working capital tied up in inventory dilute returns. The tank plant, budgeted at ₹20-25 crore for one acre, is a smaller backward-integration project intended to bring in-house tanks equal to 5-8% of turnover and ease supply; management said the margin benefit is modest because steel and iron are only 6-7% of transformer cost.
Competitive position rests on qualification. The company has long supplied utilities and has type-tested up to 25 MVA/110 kV at CPRI. Higher-voltage utility and data-centre work requires larger type tests and vendor approvals. Management targets PGCL approval within a year and says type-test certificates for 50 MVA and 100 MVA are under process; a 50 MVA unit for a customer is getting ready. Data centres are a real demand pool but not yet an order pool: management had received no data-centre order as of Q2 FY27 and said credentials and type tests for 160-200 MVA extra-high-voltage transformers are needed. The prior December 2026-January 2027 CPRI test plan was not updated. Passing these gates would widen the addressable market; failing or delaying them keeps the company in the more crowded lower-voltage segments.
Capital allocation is split between the completed Kannur build, the small tank plant and a future greenfield expansion. The next expansion is only to be planned next year and will be much bigger, with no size, land or budget disclosed. That is not yet a committed capex number. Working capital is the nearer constraint. Management plans to hold ₹60-70 crore of inventory to support the ₹300-350 crore revenue plan and expects cash flow from operations to turn positive in H2 FY27. Receivable days were 94 at the end of FY26, down from around 210 two years earlier, but the order book's spill into FY28 ties up cash. If bank limits or customer collections lag, the revenue plan competes with working capital for funding.
Management delivery is mixed but not broken. The physical Kannur plant was delivered broadly on schedule, with commercial production confirmed by June 2026. FY26 revenue was cut from ₹200-250 crore to ₹180-200 crore and came in at ₹182.1 crore, at the bottom of the revised range. The Q4 FY26 new-plant contribution promised at ₹30-40 crore was missed; the full-year contribution was ₹20-25 crore. PAT margin was held inside the promised band. In Q2 FY27, FY27 revenue guidance was raised to ₹300-350 crore and FY28 peak revenue to ₹550-600 crore, while the PAT margin band was trimmed to 9-12%. The correct reading is that physical execution has been better than the revenue ramp attached to it. The next twelve months test whether the upgraded revenue numbers are delivered or reset again.
The falsifiers are concrete. FY27 revenue below ₹300 crore would show the H2 execution plan did not hold against the ₹353 crore customer requirement. PAT margin below 9% would show price-variation cover is insufficient for the 20-30% of the book not covered. Kannur utilisation below 40-50% this year or below about 80% next year would defer the ₹550-600 crore peak revenue target. Delay in PGCL approval or the 50 MVA/100 MVA type tests would keep higher-voltage utility and data-centre orders gated. Operating cash flow failing to turn positive in H2 FY27 would leave the growth funded by inventory and bank lines. If those markers hold, the compounder case is that a small transformer manufacturer uses a qualified 9,000 MVA asset to earn a mid-single-digit-to-low-double-digit PAT margin on a much larger revenue base. If they fail, the company remains a capacity-rich but qualification- and working-capital-constrained supplier.
