Analysis: Waaree Renewable Technologies Ltd.

Growth thesis

Waaree Renewable Technologies is an EPC contractor for solar, battery storage, and transmission and distribution projects, with an O&M portfolio of 1.15 GWp and own IPP assets of 82 MWp operational plus a 198.6 MWp pipeline. In Q1 FY27 it executed 888.81 MWp of solar EPC and carried a consolidated unexecuted order book of INR5,300 crore, of which roughly INR2,400 crore is pure solar EPC, INR200 crore is BESS, and the balance sits in T&D through the 55% acquisition of Associated Power Structures. The standalone solar EPC EBITDA margin has historically delivered near 19%, while the consolidated margin is around 15% because of the lower-margin T&D business. The competitive structure is fragmented in solar EPC with many new entrants, but the T&D side brings two decades of execution and an in-house fabrication and galvanization capacity of 108,000 metric tons per annum, which gives a cost and execution edge that pure EPC players cannot easily replicate.

The economics persist because the T&D business carries real barriers: qualification cycles are long, substation and transmission projects require proven capability and manufacturing depth, and the integrated solar plus power evacuation solution creates switching costs for developers. The O&M contracts, which are typically added on project completion, increase customer stickiness over time. Management does not chase unprofitable tenders, and its ability to hold standalone solar EPC EBITDA above 19% despite intense competition suggests disciplined selection. However, 30-40% of the order book comes from group entities, which raises a revenue-quality concern, and the solar EPC segment itself has limited pricing power, so the moat is not in solar alone but in the combination of solar, BESS, T&D, and in-house manufacturing that forms a full value chain for grid-connected renewable projects.

The inflection is the acquisition of APSPL and the simultaneous ramp in T&D and BESS execution. Over the next 18-24 months, the INR5,300 crore unexecuted order book is slated to be completed within 12-15 months, implying a steady execution pace, while the company pursues a domestic solar EPC pipeline of roughly 27 GW, an international pipeline of 10-11 GW, and a T&D order pipeline of about INR20,000 crore. By mid-2028, the business should look materially different: T&D and BESS will likely contribute 30-40% of revenue, the IPP pipeline of 198.6 MWp will be progressively commissioned to create recurring cash flows, and consolidated EBITDA margins should recover from the current near-15% level toward 18% as APSPL's ~11% margin is lifted through process improvements and as higher-margin IPP and BESS projects mix in. The timeline for APSPL order execution is typically 18-24 months for larger substations, which aligns with the 18-24 month horizon, but no specific commissioning dates have been promised.

Management has consistently delivered above its stated 15% EBITDA threshold historically, with FY26 standalone margin at 19.24% and 9M FY26 at 19.48%, and it has not cut any guidance despite the margin dip from consolidation. On the August and July 2026 calls, management reiterated its intention to hold consolidated EBITDA at around 15% for FY27 while explicitly stating the INR5,300 crore order book will be executed over the next 12-15 months and that it will work to improve APSPL's margins through operational efficiency. The acquisition was funded with 75% debt, which will raise interest costs in the near term, but the company has no fund-based working capital borrowings and uses its own cash generation to fund IPP capex of INR3-3.5 crore per MWp, indicating a conservative capital allocation stance with no dilution so far.

The quantified earnings path is tied to order book conversion and order inflow momentum. If the current INR5,300 crore book is executed evenly over 12-15 months, quarterly revenue would run around INR1,000-1,100 crore, similar to the Q1 FY27 run-rate of ~INR1,150 crore implied by EBITDA of INR173.48 crore at a ~15% margin. Growth comes from converting the 27 GW solar and INR20,000 crore T&D pipelines into firm orders, which is the single most important watchpoint. The falsifiers are clear: if related-party orders are not economically independent, or if T&D margins remain stuck near 11% due to competition and rising input costs, the structural improvement thesis breaks. Additionally, working capital days may stretch beyond the guided 60-90 days if T&D project execution encounters terrain or clearance delays, so quarterly order inflow, consolidated margin trajectory, and working capital trends will be the decisive metrics to track.
