How durable is the business?
The segment is expanding through the acquisition of Hobel Bellows, which adds specialized capabilities in metal forming and hydroforming. Management guides for a conservative 15-17% growth rate over the next 3-4 years, driven by a $2.6 billion global addressable market. (1 expanding)
“For the year ended 31st March 2026, Hobel Bellows reported approximately INR129 crores in revenue... we see a clear pathway to scale the business assuming conservative growth rate of 15% to 17% over the next 3 to 4 years.”
The segment has evolved into 'Aero Tooling / MRO Tooling' which now includes specialized engine tools for LEAP, Pratt & Whitney, and Rolls Royce. While specific revenue share for bellows isn't isolated, the segment's capacity has grown significantly. (5 expanding across 2 engines)
“I should say more than 75% is being contributed by bellows and rest comes from exhaust manifolds and other structural components.”
The company remains heavily export-oriented at 95%, though it is actively working to reduce US-specific exposure and increase domestic share to 20% over three years. (1 expanding, 1 shifted, 3 stable)
“Hobel has built a long-standing relationship with marquee global OEMs, with nearly 90% of its revenues derived from exports, catering to markets including UK, United States, Singapore, and China.”

Where does growth come from?
The order book remains healthy at INR 81 crores (810 mn) as of June 2025, with management explicitly expecting a surge in order flow during the next two quarters. (2 new trend across 2 signals)
“So Krisha, so the current order book as we have seen is for the next 6 months there's an outstanding order book for INR65 crores plus is what we have understood.”
Capacity is accelerating rapidly with floor space increasing from 180k to 213k sq ft in one quarter, and a target of 300k sq ft. Machining hours tripled year-over-year. (3 accelerating, 2 decelerating across 5 signals, 3 leading indicators)
“For the year ended 31st March 2026, Hobel Bellows reported approximately INR129 crores in revenue... we see a clear pathway to scale the business assuming conservative growth rate of 15% to 17% over the next 3 to 4 years.”
The company is seeing traction in the semiconductor space with 52-week order visibility and is qualifying for high-volume manufacturing, viewing semiconductors as a 'gold rush' opportunity. (1 new trend, 1 accelerating across 2 signals)
“So there is -- we see a rising global demand for high power and emission efficient power generation systems driven by increased deployment of data centers and advancements in AI.”
The company maintains its AS9100 D certification, which is a critical entry barrier for global aerospace work, and is now leveraging this to expand into the USA and European markets. (1 steady, 1 accelerating across 2 signals, 1 leading indicator)
“So the key drivers include a strong and growing addressable market for metallic bellows estimated at around 2.6 billion with expected annual growth of 6%... the first task is going to be getting into that [AS9100] certification followed by qualification.”

What could break the thesis?
Revenue growth has stalled (only 1% YoY in Q2) and the company has officially retracted its 40% revenue growth guidance for FY26 due to structural shifts in customer buying behavior. (3 intensifying, 2 easing, 1 high-severity)
“but there are two key OEMs or the OEM groups who contribute close to around 93% of their revenue.”
INTENSIFYING. Management explicitly noted slowness in the export market due to 'tariff news' and uncertainty regarding US tariff finalization on August 1st. They anticipate potential margin compression of 15-20% if forced to share costs with customers. (3 intensifying, 2 easing)
“Hobel has built a long-standing relationship with marquee global OEMs, with nearly 90% of its revenues derived from exports, catering to markets including UK, United States, Singapore, and China.”
The risk is intensifying as the company is actively preparing for EMCCR tenders and nuclear projects, where certification timelines are critical for revenue realization. (1 intensifying, 2 stable, 1 easing)
“And the last question from me is like the NPCIL certification that you are talking about is for Hobel, right? And like how much time it will take? Management: Yes, about a year's time.”
