Strengths & risks

The case for and against, from the DRHP's own numbers and risk factors.

Strengths · 6

  • 01The company has been in turnkey engineering projects since 1994 and holds ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018 certifications that help it meet tender pre-qualification norms.
  • 02The order book was Rs 217.24 crore on 30 June 2026, spread across its four business verticals.
  • 03EBITDA rose from Rs 3.65 crore in FY2024 to Rs 12.03 crore in FY2026, and EBITDA margin rose from 3.10% to 11.37%.
  • 04Repeat customers gave 93.60% of FY2026 revenue from operations and 99.26% in FY2025, which points to long client relationships.
  • 05Total borrowings fell from Rs 30.27 crore at 31 March 2025 to Rs 20.83 crore at 31 March 2026, and debt to equity was 0.16.
  • 06Promoters and promoter group hold 78.89% before the issue.

Risks · 9

  • 01The largest customer gave 75.61% of FY2026 revenue from operations and the top 5 customers gave 92.22%, so losing one client would hurt badly.
  • 02Operating cash flow was negative in all three years: Rs -15.08 crore in FY2026, Rs -3.21 crore in FY2025 and Rs -16.14 crore in FY2024, even though FY2026 profit was Rs 8.04 crore.
  • 03Revenue from operations fell from Rs 139.99 crore in FY2025 to Rs 105.83 crore in FY2026, and PAT fell from Rs 12.89 crore to Rs 8.04 crore.
  • 04The company made a loss of Rs 6.71 crore in FY2024.
  • 05Turnkey engineering projects gave 59.67% of FY2026 revenue from operations, and most work comes from the oil and gas industry.
  • 06A large part of the business comes from tenders of government undertakings, with exposure to liquidated damages and bank guarantee invocation if projects are delayed.
  • 07The company owns no vessels and depends on customers for vessels and marine assets, and monsoon disrupts work on the high seas.
  • 08Up to Rs 82.50 crore of the fresh issue goes to long-term working capital, and general corporate purposes can take up to 25% of gross proceeds, with the amount not yet fixed.
  • 09The company faces 50 tax proceedings against it, and the order book of Rs 217.24 crore may be delayed, changed or cancelled.
