Borderline, landed KILL. Re-check at first results.
Why:
- The service has no price edge, so the market comes slowly. Piped steam costs its buyers about ₹3.21 a kilo, inside the ₹1.8 to ₹6.0 range the filing itself gives for running your own boiler (T1). What sells it is convenience and compliance, not savings, which is why shared boilers are still about 3% of the pool after twelve years, the push from regulators is a recommendation rather than a rule (T1/T2), and 65% of the company's own built capacity sits idle.
- The business was built on debt that the IPO now repairs. Borrowings reached about four times operating profit, the rating agency downgraded the company in 2024 for project delays and falling realisations with interest cover dropping from 6.5x to 3.9x (T2), and half the fresh money repays loans, including the entire bond issue whose payoff frees the promoter's pledged 76% stake. Another ₹109 crore, more than the whole new-boiler programme, is raised with no stated use (T1).
- The promoter group sits on every side of the table, and one number does not add up. The promoter's own textile mill is the largest customer, taking ₹90 crore of traded coal a year, which is nine to twenty times what a mill that size can burn; where the rest goes is not disclosed (T1/T2). The mill also supplies steam, lends money, owns the original plant and licenses the land, all disclosed, all asserted as arm's length, none evidenced.

The filing's chosen peers (two industrial-gas companies) average 70.96x earnings, so the offer prices below the set the issuer picked, though neither peer runs coal boilers (T1). The price does not move the verdict: the six ratings judge the business, not the band.
The story
A buyer is buying a set of small local monopolies: once Steamhouse lays the only steam pipe through a Gujarat industrial estate, the factories on it have one supplier. The mature estates make real money. The bet is that the two-thirds of built capacity now idle fills up, and that more factories choose piped steam over owning a boiler. The catch is that piped steam saves them little money, so they switch slowly.
What this business is
The company runs seven coal-fired boiler plants (345 tonnes of steam an hour) in industrial estates around Surat, Vapi, Ankleshwar, Panoli, Sarigam, Nandesari and Dahej, and pipes metered steam to 202 factories, mostly dyeing, chemicals and pharma. Customers avoid buying, running and getting pollution clearance for their own boilers; 90.7% of revenue is repeat business, and names like Lupin and Atul are on the pipe (T1/T2). It also resells steam bought from the promoter's mill and from third parties, runs a waste-to-energy steam unit at Vapi, has one customer on a small nitrogen pipeline, and trades coal at about a 2% margin, which is a third of reported revenue and makes the headline growth look faster than the steam business grew (T1).
Easy or difficult business? A capital-heavy local utility. The hard parts are winning the estate rights, laying kilometres of pipe, and running boilers efficiently, and once the pipe is down a rival is unlikely to lay a second one. The genuinely hard commercial part is filling a plant after building it: the company builds first and sells later, its newer estates are years behind plan, and the rating agency downgraded it for exactly that (T1/T2).
Key numbers
| ₹ cr | FY2024 | FY2025 | FY2026 |
|---|---|---|---|
| Revenue | 292 | 395 | 492 |
| Revenue growth % | n/a | 35.4 | 24.4 |
| EBITDA | 68 | 69 | 83 |
| EBITDA margin % | 23.4 | 17.5 | 17.0 |
| PAT | 27 | 31 | 39 |
| PAT growth % | n/a | 14.6 | 24.0 |
The margin fall is mostly an optical effect: near-zero-margin coal trading grew from nothing to ₹132 crore of revenue, swelling the denominator. Measured on a like-for-like base the margin is roughly flat at 23 to 24%, and the steam business itself earned more per tonne in FY2026 than the year before (T1). FY2025 profit growth leaned on a tax swing; FY2026 is at the normal tax rate (T1).

Scorecard
| Block | Rating | Why |
|---|---|---|
| Right to win | PASS | The customer's reason is real: steam arrives by pipe, metered, with no boiler to buy, staff, fuel or get cleared with the pollution board, and switching back means capital spending. The pipe itself is the moat: 60 km of it across the estates, ten-year usage rights, and no rival pipe behind it. The numbers show it working where it is mature: 202 customers, up 62% in two years, 90.7% repeat revenue, own production up 22% and margin per tonne at a three-year high (T1). Limits: the price gives customers little saving, contracts carry no minimum offtake, and 30 customers terminated in the period. |
| Industry and TAM | MARGINAL | The pool of steam raised in its clusters is far bigger than its ₹343 crore of steam revenue, but shared boilers are ~3% of it after twelve years, the regulator recommends rather than requires them, and the issuer's claim to 36% of the segment fails its own arithmetic (T1/T3). Growth is real and slow. |
| Financial momentum | MARGINAL | Steam economics improved in FY2026 and new plants commissioned earn about 20% on their capital, above the cost of debt; but the build ran on borrowings near 4x operating profit, the rating was cut in 2024 on delays and falling realisations, and reported operating cash flow is flattered by unpaid equipment bills (T1/T2). |
| Risks, governance, RPTs | MARGINAL | No money leaves toward the promoters, audits are clean, and the debt being repaid funded plants, not family. Held down by the unexplained coal volumes to the promoter's mill, a pollution show-cause notice on the showcase waste-to-energy plant with two plants run ahead of final consent, and related-party dealings around a quarter of revenue with no third-party pricing shown (T1/T2). |
| Promoter and cap table | MARGINAL | A genuine builder, independently confirmed, selling only 4% of his stake. Held down by a corroborated record of late, over-budget projects; a share history in which group companies moved 91% of the company to him at face value in 2021 while outsiders paid ₹51 within a year; placements at ₹200 in 2024 and ₹73 in 2026 on the same share base; and a small aircraft-charter venture leased from the family's US entity during the IPO run-up (T1/T2). |
| Offer structure | MARGINAL | 85% of the offer is fresh money and the boiler capex ties to the stated strategy. But half the fresh issue repays debt whose retirement also frees the promoter's pledged shares, the profit boost from that repayment is small once the real interest line is read, and ₹109 crore, more than the entire boiler programme, is raised with no stated use (T1). |
Watch out for
- The coal arithmetic. ₹90 crore a year of coal sold to the promoter's dyeing mill implies many times the coal such a mill can burn. Either it resells the rest, or someone else does; the filing does not say (T1/T2).
- The rating history is the independent record. Downgraded in October 2024 for commissioning delays and falling realisations; never upgraded through the build-out; the municipal waste-heat project is over a year past its contracted date with a penalty clause so far unenforced (T2).
- The pledge and the repayment travel together. The bonds being repaid with IPO money are the ones whose covenant released the promoter's 76% pledge in August 2026; the release is conditional and carries no timeline or risk factor (T1).
- A pollution notice sits on the flagship. The Vapi waste-to-energy unit, the company's best-running new plant, carries a show-cause notice, and two plants operated ahead of final consent (T2).
- New estates are the test. Sarigam is at ~12% utilisation in year three and Panoli at 7% at commissioning, both blamed on the chemicals downturn; the IPO builds 180 tonnes an hour more (T1).
The offer
- Raising ₹414 crore in total: ₹353 crore of fresh money plus a ₹61 crore offer for sale by the promoter, about 4% of his holding (T1).
- For ₹180 crore of debt repayment, ₹114 crore of new boiler capacity at three estates, and ₹109 crore of general purposes with no stated use, which is more than the entire boiler programme (T1).
- Implied valuation: the table at the top carries it, ₹2,149 to ₹2,242 crore at the band.
- Promoters: the family holds 95.0% before the offer and about 76 to 77% after, still above the 75% ceiling, so further selling is mandated within the listing rules' timeline (T1).
Assessment of the Red Herring Prospectus dated 3 September 2026 under the orchestrated process. Outside checks of the rating record, regulators and competitors were made and are marked where used (T1 regulator and court records, T2 established outside reporting with a named source, T3 sell-side or press); the price band, lot and offer dates come from the NSE and BSE public records. Numbers otherwise carry (T1) for the filing's audited sections and (T3) for its issuer-commissioned industry chapter. Not a recommendation. The valuation section states what the announced band implies and is not a view on whether that price is right.
