Key themes
Heavy engineering scale-up and margin recovery
How the narrative shifted
- Heavy engineering integration and value chain shift: Management emphasizes that moving from consumables to integrated heavy engineering solutions increases order size, customer stickiness, and competitive advantage.
- Capacity expansion for next growth phase: The new Nagpur facility doubling heavy engineering capacity to 18,000 MT is the key enabler for executing larger orders and sustaining high growth rates.
- Raw material headwinds and margin recovery: Raw material price spikes and volatility pressured gross margins in Q4 and Q1, but stabilization and customer acceptance of price hikes are expected to support margin recovery.
- International market penetration: UAE facility ready for manufacturing, Turkey turned profitable; international markets are positioned as a meaningful medium-term growth opportunity beyond product exports.
- New high-value applications: Railways & Defence: The company is progressing qualification for Vande Bharat ecosystem and defence subassemblies, though gestation is long; these are extensions of core engineering capabilities.
Operational commentary
- Heavy engineering capacity doubling to 18,000 MT: new Nagpur facility started phased commissioning, adding machining capability and integrated manufacturing.
- UAE manufacturing facility ready; revenue contribution expected from Q2. Turkey business turned profitable with increasing revenue.
- New product pipeline advancing: VRM rollers and steel mill rollers gaining initial orders; high-volume wear parts being promoted.
- Railways: workshop approval process underway for Vande Bharat ecosystem parts; small developmental orders received; 9-12 month conversion timeline for tenders under evaluation.
- Defence: associate Tejorup developing VSHORADS prototype; existing flux-cored wire orders for defence contribute ~1.5-2% of revenue; pursuing subassembly opportunities.
- Order book diversification: welding consumables order book jumped, reflecting customer consolidation of yearly requirements and increasing maintenance demand.
Analyst Q&A
Q. What is the Top 10 customer concentration in overall revenue or heavy engineering?
Honestly, we don't have that answer ready, maybe we can check from our ERP and send you a separate reply for that. The nature of the business hasn't changed much; anywhere between 60% to 70% is what we expect it to be.
