Steamhouse India is set to list on the BSE and NSE on Thursday, September 17, riding a speculative wave that pushes its grey market premium (GMP) to ₹13.5. At the upper price band of ₹81, this suggests a debut price around 17% above the issue rate. While GMPs are volatile and often fade on listing day, the current sentiment reflects strong demand for industrial infrastructure plays, even as the stock hasn't technically entered public hands yet.
The subscription data tells a story of institutional confidence rather than just retail frenzy. The issue closed 30.49 times oversubscribed on September 11. Non-institutional investors (NIIs) led the charge at 44.30 times, followed closely by Qualified Institutional Buyers (QIBs) at 43.91 times. Retail investors chipped in at 16.90 times. This distribution suggests smart money is backing the asset, not just retail investors chasing a hot ticker. The total issue size is ₹414 crore, comprising a fresh issue of ₹353 crore and an Offer For Sale (OFS) of ₹61 crore. Equirus Capital is the sole book-running lead manager.
Fundamentally, the numbers show a business scaling fast but with margin pressure. Revenue jumped over 50% to ₹494.97 crore in FY26 from ₹293.16 crore in FY24. EBITDA rose to ₹83.49 crore in FY26 from ₹69.32 crore in FY25. However, efficiency is slipping. EBITDA margins compressed to 16.87% in FY26, down from 17.4% in FY25 and a much healthier 23.34% in FY24. Profit After Tax (PAT) margins held steady at 7.81%. For a utility-style business, maintaining margin percentage while scaling volume is the key metric to watch post-listing.
Valuation is tricky here because Steamhouse lacks a direct listed peer. It operates community boilers and nitrogen pipelines in Gujarat’s industrial clusters like Vapi and Sachin. Comparisons often draw it to Linde India or the recently listed Ellenbarrie Industrial Gases, but the business models differ significantly. Steamhouse is a localised utility; Linde is a global industrial gas major. At the ₹81 issue price, Steamhouse trades at a 57.86x post-IPO P/E. Linde’s multiple is higher, but its scale and diversification aren't comparable. Steamhouse posted a 22.36% Return on Equity in FY26, outpacing Linde’s 13.8%, which supports the higher P/E if margins stabilize.
For investors, the listing on September 17 is the immediate catalyst. The 17% GMP premium is a strong start, but it’s not a guarantee. The stock will need to prove it can sustain its 50% revenue growth without further margin erosion. Watch the first few trading sessions for volatility. If it lists above ₹95, it may face a correction as early buyers take profits. The key question for long-term holders is whether the community boiler model can scale beyond Gujarat without the capex eating into those 16% EBITDA margins.
