Borderline, landed KILL. Re-check at first results.
Why:
- Growth: the reported 36.5% is roughly 20% once a tariff pass-through is stripped, and it is slowing. The United States put a 50% tariff on imported steel structures in 2025. Karamtara's American customers reimburse that duty, and the ₹577 cr they reimbursed in FY2026 is booked as revenue with a matching cost, so it inflates sales without touching profit (T1, disclosed by the company). On the company's own adjusted-revenue line, growth was 21.4% in FY2026, down from about 25% the year before. The tariff is not going away: the February 2026 US-India trade deal cut other tariffs but left the 50% steel tariff in place (T3).
- Position: the customers own the designs and can leave on short notice. About four-fifths of revenue is solar structures built to drawings supplied by tracker companies and EPCs. There is no order book, no long-term volume contract, and the filing says customers can switch suppliers at short notice (T1). The one listed company doing comparable work, KP Green Engineering, grew about 79% last year at a 20% EBITDA margin against Karamtara's 14.6% on the same adjusted basis (T1, the filing's own peer table).
- Debt and cash: real borrowings are 3.2 times operating profit, and less than half of profit became cash. The headline says 1.8x, but it leaves out ₹698 cr of bank acceptances sitting inside trade payables that the filing itself calls "akin to any other borrowing" (T1). Counting them, working capital is about 102 days of revenue, not 43. Across three years the company burned about ₹925 cr of free cash while building capacity, and it discloses no order book to fill it (T1).
Why this is BORDERLINE and not a plain KILL: the verdict engine lands one grade from TRACK. The market itself is genuinely good: India installed a record 36.6 GW of solar in 2025 and tracker use is rising fast (T3), the company's plants that existed a year ago ran fuller this year than last (T1, derived), volumes grew 29%, and it is prequalified with 16 of the top 24 American solar builders with real shipments confirmed in US customs records (T2). If Karamtara turns those qualifications into a durable customer hold, the business answer improves and the verdict flips. The first results after listing decide.

The filing's own peer table tops out at a P/E of 30.15 and averages 19.18 (T1), so the offer is priced above every company the issuer chose to compare itself with. The price does not move the verdict; the six ratings judge the business, not the band.
The story
A buyer is buying India's largest solar mounting-structure fabrication estate: 13 plants and 889,200 tonnes of annual capacity that turn bought-in steel into mounting structures, tracker parts, transmission towers and wind towers, mostly to the customer's own drawings. Solar is 79% of revenue. The whole thesis is whether that estate stays full at a rising conversion margin, and today the designs, and therefore the pricing power, belong to the customers.
What this business is
Karamtara buys steel, rolls, fabricates and galvanizes it, and ships finished structures: mounting frames and tracker components for solar farms, lattice towers for power lines, tubular and angular towers for wind turbines, and fasteners. Customers are solar tracker companies and engineering contractors in India and the United States, plus power utilities. It earns a conversion margin of roughly ₹9,500 per tonne on about 525,000 tonnes shipped in FY2026 (T1, derived).
The company grew capacity 81% in two years, commissioning five new plants on schedule, and is building a plant in Saudi Arabia funded by its own borrowings (T1). Exports were 76% of revenue three years ago and are 40% now; the growth this year came from India (T1).
Easy or difficult business? Mid-difficulty. Anyone can fabricate steel, but qualifying with global solar builders takes years of audits and certifications, and Karamtara holds them: European structural marks, carbon-border registration, and approvals from 16 of the top 24 US solar contractors (T1). What it does not hold is the design. The tracker companies it supplies own the technology and hand over drawings, so the work is skilled contract manufacturing rather than a product of its own.
Key numbers
| ₹ cr | FY2024 | FY2025 | FY2026 |
|---|---|---|---|
| Revenue | 2,425 | 3,158 | 4,312 |
| Revenue growth % | n/a | 30.2 | 36.5 |
| EBITDA | 263 | 347 | 498 |
| EBITDA margin % | 10.8 | 11.0 | 11.6 |
| PAT | 103 | 139 | 229 |
| PAT growth % | n/a | 35.7 | 64.2 |
FY2026 revenue includes the ₹577 cr American tariff reimbursement, which has no profit in it; on the company's own adjusted line, revenue is ₹3,423 cr and the EBITDA margin 14.6% (T1). PAT grew faster than revenue mainly because the tariff item carries no cost below the EBITDA line and the FY2026 margin gained from cheaper steel and a currency gain (T1, derived).
| Segment, ₹ cr | FY2024 | FY2025 | FY2026 |
|---|---|---|---|
| Solar products | 1,983 | 2,571 | 3,406 |
| Solar products growth % | n/a | 29.7 | 32.5 |
| Transmission towers | 101 | 165 | 274 |
| Transmission towers growth % | n/a | 62.9 | 65.9 |
| Fasteners | 145 | 208 | 234 |
| Fasteners growth % | n/a | 43.6 | 12.3 |
| Wind towers | 0 | 2 | 135 |
The solar line carries the tariff reimbursement; stripped of it, solar grew about 12% in FY2026 rather than 32.5% (DERIVED, the filing does not allocate the recovery by product).
Scorecard
| Block | Rating | Why |
|---|---|---|
| Right to win | MARGINAL | The real assets are prequalifications with top US builders, confirmed by customs records, an execution record of five plants commissioned on schedule, and India's biggest solar galvanizing estate. But the customers own the designs, nothing is contracted, there is no order book, and the one listed peer doing the same work grows faster at a better margin. A capable contract fabricator, not a business with a hold on its customers. |
| Industry and TAM | PASS | India installed a record 36.6 GW of solar in 2025 and tracker use is heading from about a third of projects toward more than half, which means more steel per megawatt (T3). The company's own growth pools, torque tubes and foundation piles, compound at 15 to 17% (T3, commissioned). The caution: the US half of the market shrinks in 2026 under the 50% steel tariff, and Karamtara's share of the booming home tracker market has been drifting down. |
| Financial momentum | MARGINAL | Real growth is about 20% and slowing. The margin gain is mostly steel prices and a currency gain, not scale. Counting acceptances, debt is 3.2x EBITDA, under half of profit became cash, and three years of building consumed about ₹925 cr of free cash. Volumes grew 29% and returns on productive capital are decent; the balance sheet behind them is stretched. |
| Risks, governance, RPTs | MARGINAL | A 2024 CBI charge sheet names the sitting chairman and CFO over 2013 letter-of-credit invoices, unadjudicated and disclosed; the MD gave a personal statement to the ED; a customs inquiry covers the whole export book since 2022, unquantified; a company-law matter went to the NCLT the day before this RHP was filed (T1). Each is disclosed; together they are a file. |
| Promoter and cap table | PASS | The execution record is emphatic and the structure is clean: no pledge, a simple share count, promoters selling only 2.4% of their own holding. Watch-outs listed below. |
| Offer structure | MARGINAL | ₹600 cr of the ₹675 cr fresh issue repays working-capital borrowings the filing says will be drawn again, the second balance-sheet repair in twenty months. General corporate purposes take about a fifth of the primary money counting a pre-IPO placement. The clean part: 77% of the offer is fresh money and the promoter sale is small. |
Watch out for
- A CBI charge sheet from October 2024 names the sitting chairman-MD and CFO over allegedly non-genuine invoices against 2013 letters of credit; a petition to quash it is pending (T1). Unadjudicated, fully disclosed, and the reason the governance block is not clean.
- The company sold a Mumbai flat to a promoter for ₹48.5 cr, at roughly its eight-year-old cost, with no valuation disclosed and it is the same property the company-law inspector had flagged (T1).
- ₹158 cr of today's share value moved to two executives' family vehicles at ₹4.02 a share three weeks before outside investors paid ₹310, with no charge in the accounts and the consideration mechanics undisclosed (T1, derived).
- The last pre-IPO investor got in at an effective ₹254 a share, 18% below the ₹310 paid in January 2025, and the family took a ₹14.6 cr dividend eleven weeks before filing (T1).
- The filing's two revenue-by-geography tables disagree by about ₹630 cr on the US line. On the audited note, US revenue rose about 9% excluding the tariff; on the KPI table it rose less. The gap is unexplained (T1).
The offer
- Raising ₹875 cr: ₹675 cr fresh issue and ₹200 cr offer for sale by the two promoter brothers (T1).
- For repaying ₹600 cr of borrowings and acceptances that the filing says will be redrawn for working capital, plus general corporate purposes. No plant is built with IPO money; the announced expansions carry their own funding (T1).
- Implied valuation ₹7,790 cr to ₹8,174 cr at the band, from the table above.
- Promoters hold 92.1% before the offer, are selling about 2.4% of their own shares, and keep about 82% after (T1).
