Dee Development Engineers designs and manufactures high-specification piping systems, heavy fabrication, and seamless pipes for the power, oil and gas, and process industries, serving customers in India and export markets. Its core business also supports a separate non-core segment comprising a biomass pellet plant and a power plant. In the niche of HRSG piping for gas turbine combined cycle plants, management states there is practically no competition in India beyond one or two players with far less capacity, with global rivals mainly from Korea and Turkey. This positions the company as a preferred supplier to major OEMs like GE, Nooter Eriksen, Mitsubishi, and Siemens. As of June 30, 2026, the order book stands at Rs 2,428 crore, while Q1 FY27 EBITDA margin came in at 16.9 percent versus 16 percent a year earlier, with management guiding to above 19 percent for the full fiscal year. The money is made through high-value engineered piping that carries qualification barriers and long customer ties.
The economics persist because of multiple, compounding barriers that are time-intensive to replicate. Supply of alloy steel seamless pipes in P91/P92 grades is scarce globally; the company's new seamless pipe plant is a backward integration that captures margin and reduces import dependence. Customers undergo lengthy qualification cycles, and the company has sealed long-term capacity reservation and volume agreements, notably Nooter Eriksen's reservation of 60 percent of Thailand facility capacity, which equates to roughly Rs 150 crore in annual job work. A Siemens MoU begins with 10 GT piping units next year, scaling to 15 and then 25 to 30 units over three years, with each unit valued between 1 and 1.5 million euros. The receipt of a Rs 386.82 crore BPCL order, one of the largest single orders in company history, further demonstrates the trust PSU refineries place in its delivery record. These agreements and qualifications take years to build, creating a durable moat.
The inflection is happening now because the Anjar heavy fabrication facility and the seamless pipe plant are both commissioned and ramping up. Management expects Anjar to reach 60 to 65 percent utilization by end FY27 and near 100 percent by the following year, while the seamless pipe plant is guided to ramp to 60 to 70 percent utilization in FY27. This capacity, coupled with strong order inflow visibility of at least Rs 2,000 crore for FY27, supports a conservative revenue target of Rs 1,500 crore for FY27 and a longer-term goal of Rs 2,500 crore by FY29, pulled forward from the original FY30 target. Eighteen to twenty-four months from now, the business should be generating revenue close to Rs 2,500 crore with EBITDA margins above 19 percent, aided by higher utilization, backward integration, and the elimination of non-core power losses. Working capital days are targeted to compress from 263 to 180 to 200, which will improve cash conversion and reduce net debt to no more than Rs 400 to 425 crore by FY27 end.
Management's walk-talk record has been consistent. In the August 2025 call, they guided to FY26 revenue of roughly Rs 1,300 crore and EBITDA margin of 19 to 20 percent. At the nine-month mark of FY26, core revenue was Rs 780 crore and core EBITDA margin was 17.4 percent, but after adding back one-off items, management stated the true core margin was already 18 percent, reiterating the 18 to 20 percent range for FY27. Anjar was commissioned in Q3 FY26, ahead of the original end-August 2025 schedule, and order inflow targets for FY26 were met. In the August 2026 call, they reiterated the FY27 revenue guidance of above Rs 1,500 crore, EBITDA margin above 19 percent, and net debt at or below Rs 400 to 425 crore. The track record of delivering on previous commitments, including the seamless pipe plant's on-schedule commercial production, supports the credibility of these forward targets.
The quantified earnings path is clear. FY26 core EBITDA was Rs 210.5 crore, up 64.2 percent year on year, excluding non-core losses. With revenue moving toward Rs 2,500 crore and EBITDA margin above 19 percent, FY29 core EBITDA would approach Rs 475 to 500 crore, a more than doubling from current levels. The triggers include the tariff revision at the Malwa power plant from Rs 3.5 to Rs 5.22 per kilowatt-hour and the biomass pellet plant reaching EBITDA neutrality, which should remove the Rs 36 crore power segment drag. However, the key watchpoint is execution on capacity ramp and order flow. If Anjar utilization fails to reach 60 to 65 percent by end FY27, or if the GE HRSG order for 15 to 16 units is delayed beyond current expectations, the margin trajectory will be at risk. The gross margin decline from material-heavy power jobs is a temporary mix effect that should be offset by lower conversion costs from operating leverage and backward integration, but the single most important falsifier remains whether working capital days compress to the targeted 180 to 200 range without disrupting project execution.
