SPML Infra is an infrastructure EPC contractor generating 85-90% of revenue from government-funded water projects, with power substations and battery energy storage systems (BESS) as emerging segments. The company entered Q4 FY26 with a consolidated order book of INR5,369 crore, split between INR4,000 crore of new high-margin orders and INR1,369 crore of legacy back-to-back contracts. It ranks among the top 4-5 players in Indian water EPC and top 10 in power substations, leveraging 45 years of execution history and 700+ completed projects. FY26 EBITDA margin was 9.7%, with new orders targeted at a minimum 10% margin, while legacy orders carry lower but protected margins. This margin level is average for the EPC industry, but the mix shift toward new orders and BESS manufacturing is expected to lift it structurally over the next two years.
The persistence of these economics rests on underappreciated barriers. The 45-year track record and pre-qualification advantages create qualification cycles that are difficult for new entrants to replicate, especially for government tenders requiring proven execution and financial stability. The BESS manufacturing facility at Supa MIDC Pune, with a technology tie-up with Energy Vault, gives SPML a first-mover advantage in localizing battery pack and container production, turning a commodity input into a specialized output with manufacturing margins of 14-15%. Legacy back-to-back contracts have no working capital liability, and all new contracts include price variation clauses that protect against cost escalation. While the EPC space is competitive, the combination of selective bidding on fully funded and DPR-approved projects, plus the BESS localization, creates a defensible niche that should persist through cycles.
The inflection is the commissioning of the 2.5 GWh BESS assembly line by end June 2026, with expansion to 5 GWh and 600 containerized units by end of 2026. This coincides with the wind-down of legacy low-margin orders, which are expected to be fully executed in 2-3 years. By mid-2027, the company should have a revenue mix where new water orders and BESS contribute significantly, with a visible BESS pipeline of INR9,000 crore over the next 6-12 months providing a strong order book. Management targets more than 25% growth in both top line and margin for FY27, and with the BESS plant operational, the company expects to supply battery packs as OEM to other EPC players, adding a new revenue stream. By 18-24 months out, the business should have a higher-margin profile, with EBITDA margins moving from the current 9.7% toward the 10-15% range as BESS manufacturing scales, and a debt-free balance sheet as arbitration awards of INR627 crore plus claims of INR4,526 crore repay NARCL dues.
Management's walk-talk has been mixed but shows improvement. In the Feb 2026 call, they guided FY26 revenue growth of 25-30% and PAT growth of 40-50%, but nine-month revenue was INR594 crore versus INR624 crore in the prior year, implying a need for an unprecedented Q4. However, the Jun 2026 call reported FY26 PAT up 55% to INR76 crore, exceeding the PAT guidance, and EBITDA margin of 9.7% for the full year. The BESS plant timeline slipped from March 2026 to Q1 FY27, but the latest call confirms commissioning by end June 2026. Management has maintained the FY27 guidance of more than 25% growth and has consistently targeted an annual order book of INR5,000 crore. Capital allocation is focused on debt reduction, with NARCL dues of INR380 crore being prepaid, and the company expects to be effectively debt-free as arbitration awards are realized. The shift to the new tax regime will utilize accumulated losses of over INR200 crore, reducing tax outlay for the next few years.
The earnings path to 18-24 months is quantified by order book conversion and margin expansion. With an order book of INR5,369 crore and new orders at 10%+ margins, revenue should grow at least 25% in FY27, implying revenue of around INR1,500 crore from a FY26 base of roughly INR1,200 crore (given PAT of INR76 crore and 9.7% EBITDA margin). By FY28, BESS manufacturing at 5 GWh capacity could add INR1,000-1,500 crore in revenue, with manufacturing margins of 14-15%. The key watchpoint is execution pace, as the company depends on government fund disbursements, which were impacted by the West Asia war in March FY26. The single most important falsifier is the conversion of the INR9,000 crore BESS pipeline into firm orders and the timely commissioning of the 5 GWh expansion. If BESS orders slip or the plant ramps slower than planned, the margin uplift will be delayed, but the legacy order exit and arbitration inflows provide a floor. The tension between the missed FY26 revenue guidance and the strong PAT growth is resolved by the fact that the revenue miss was due to timing of customer disbursements, while the margin improvement from new orders is structural.
