Our verdict on Unimech Aero. isn’t the consensus take — see where we landed, and the one risk the bull case glosses over.
See the verdict — free →Does management do what it says?
The company saw a massive surge in order inflows, particularly in Q3 FY26, with the order book doubling from Sep'25 levels. (1 exceeded across 1 tracked commitment)
“Improving Order Book (INR Mn) ... Sep'25 1,048 ... As on 12th Feb'26 2,098”
The company successfully increased its stake in Dheya Technologies to 30% during the last quarter. (2 met across 2 tracked commitments)
“Acquired 16% stake in Dheya Engineering with a roadmap to acquire 30%”
Working capital currently stands at 110 days, but management reiterates the expectation that it will rise to approximately 150 days as they deliver more nuclear projects and larger GSE orders. (2 in progress, 1 met, 2 revised across 5 tracked commitments)
“thus indicating working capital to raise from current 110-days to around 150-days in future periods.”
Employee benefit expenses as a percentage of revenue stood at 20.6% for the first half of FY26, aligning with the 20-22% guidance. (1 met, 1 missed across 2 tracked commitments)
“Overall employee cost is expected to be ranging around 20% to 22% range for the fiscal, which is in line with our growth plan, and which we have anyway anticipated that.”
Revenue growth for H1 FY26 was only 4% YoY, significantly below the 35-40% target. Management acknowledged that growth remained 'soft' due to tariff-induced challenges in export markets. (1 missed, 3 in progress across 4 tracked commitments)
“We have been guiding for a growth of achievement up to Rs.1,000 crores by end of FY29.”

How durable is the business?
The regulatory moat is expanding as the company moves into the Nuclear and Jet Engine (Dheya Technologies) sectors. These require even longer qualification cycles (8-10 months for precision parts and years for engines), further insulating the business from competition. (2 expanding)
“It usually takes around 8 to 10 months to prove out to a customer. Once that clarity is available, we'll be able to give you a better sense.”
The moat is being reinforced by the establishment of a Free Trade Warehousing Zone (FTWZ) to mitigate tariff volatility and reduce lead times for global customers. (2 expanding)
“Once the FTWZ is operational, this will allow our customers to build and maintain duty-free inventories of aero engine and airframe tools... makes us an even more critical strategic partner.”
The domestic segment is poised for expansion through a massive entry into the Indian Nuclear sector. The company has submitted bids worth INR 800+ crores for nuclear modernization (EMCCR) and new reactors, representing a significant shift in the domestic revenue driver from locomotives to nuclear energy. (1 expanding)
“Overall, about INR800 plus crores we have participated in the last one month to two months [in nuclear].”
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.”

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.”
The order book has grown significantly to Rs. 105 crores as of November 2025, driven by a large $4 million (approx. Rs. 33.5 Cr) win in the LEAP engine program. This represents a substantial jump from the previously reported visibility. (4 accelerating, 1 decelerating across 5 signals)
“I would also want to highlight about our order book, which is about Rs.105 crores until the end of first week of November”

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.”
The company has maintained its AS9100 Rev D certification, which is the gold standard for aerospace quality, mitigating some execution risk for the core entity. (1 easing, 1 stable)
“ISO 9001:2015 and AS9100 Rev D Certified... NADCAP certified process including heat treatment and anodizing”
Demand appears to be stabilizing with a 6% year-on-year revenue growth and a healthy order book of Rs 810 million, though Q-o-Q revenue declined by 8%. (2 easing)
“Orders in hand Rs 810 mn as of Jun’25; expect larger order flow in in Q2 & Q3... Revenue (INR Mn) 629.9 (Q1 FY26) vs 592.1 (Q1 FY25)”
