Unimech sees Rs 855 crore order book reshape revenue mix

Unimech Aerospace and Manufacturing Limited is seeking to supplement its historically short-cycle aerospace-tooling orders with multi-year component programmes. Unimech reported a consolidated Rs 855 crore order book as of September 30, 2026, up 715% year on year, and management expects more than 590 qualified parts by the end of FY27 to support later serial production.

How is Unimech changing its revenue model?

Unimech is retaining aerospace tooling as its anchor while expanding precision components and assemblies into longer-duration customer programmes. Management said conventional aerospace tooling is generally supplied through short-cycle purchase orders, whereas component programmes can be covered by multi-year long-term supply agreements with original equipment manufacturers, or OEMs, and Tier 1 suppliers.

The H1 FY27 revenue mix shows that tooling remains the larger business. Of consolidated H1 FY27 revenue of Rs 231 crore, aerospace tooling contributed about 67%, while precision components and assemblies, or PCA, contributed 33%. Hobel Bellows represented 30% of total H1 revenue, meaning PCA activity excluding Hobel was still at an earlier stage of development, according to management.

Unimech reported H1 FY27 revenue growth of 85% year on year and an earnings before interest, tax, depreciation and amortisation, or EBITDA, margin of 38%. Management linked its planned mix transition to precision-component opportunities across aerospace, defence, semiconductors, capital equipment, energy and nuclear applications, while presenting tooling as the business that continues to generate established engine and airframe demand.

What supports Unimech's Rs 855 crore order book?

Unimech said its Rs 855 crore consolidated order book contains firm purchase orders, long-term supply agreements and award letters, rather than only short-cycle tooling orders. The order book was reported as of September 30, 2026 and was 715% above the year-earlier level, according to management.

Rs 589 crore of the total order book related to long-term wins and award letters across three identified aerospace programmes. Management cited a five-year FACC agreement for aerostructure components, a Honeywell Aerospace agreement for engine components and control systems lasting 10 years and extendable by two years, and a French Tier 1 aerospace programme with indicated visibility over 10 years.

The order book is not equivalent to immediately deliverable revenue because customer qualification and prototype prove-outs can remain necessary before serial supplies begin. Management said it had customer exhibits supported by purchase orders for the aerospace programmes, while a semiconductor example showed that 60 qualified parts had moved into revenue production after qualification.

Management also said the FACC contract was worth about USD 7.5 million over five years and was in initial execution. It indicated that ongoing qualification and discussions could potentially extend the agreement's tenure and value, but this was a possibility described by management rather than a disclosed contract amendment.

How could qualified parts generate recurring production revenue?

Unimech had qualified more than 250 parts across its PCA customer base by the end of H1 FY27, with another 340-plus parts in the throughput pipeline. Management expects this combined base to exceed 590 qualified parts by the close of FY27 and said serial production from the qualified pipeline would begin contributing from FY28 and beyond.

The aerospace qualification target is more than 320 parts during FY27. These parts are undergoing first article inspection, or FAI, during the fiscal year, and management said their production ramp would follow customer approvals and scaling of serial programmes. This sequence differs from a shorter tooling order because it requires engineering, inspection and qualification before recurring deliveries can start.

Semiconductor operations had begun contributing revenue in H1 FY27, though management described the contribution as small and expected a step-up in H2. Unimech said it had invested for 20 months in the semiconductor domain, qualified 60 FAI parts, and targeted another 20 components and assemblies by the end of calendar 2026.

The semiconductor work includes precision metal and plastic machine portfolios and higher-precision mechanical sub-assemblies for customers' core equipment. Management expects H2 FY27 revenue to exceed H1's Rs 231 crore with similar margins, citing semiconductor capital-goods OEM deliveries, nuclear-order execution and steady performance in other businesses.

What execution milestones does Unimech need to meet?

Unimech must complete manufacturing and certification milestones to support component programmes included in its pipeline. At its existing facility, it is installing automated special-process cells and assembly lines, with trial runs taking place in October and November 2026, commissioning targeted for December 2026 and Nadcap certification targeted for March 2027.

The planned in-house processes include anodizing, electroless nickel plating, passivation, zinc and cadmium plating, heat treatment, surface finishing and non-destructive testing. Management said these capabilities are intended to improve control of quality, lead times and process traceability for aerospace and semiconductor customers; subcontracting costs were 2% of H1 FY27 revenue.

Manufacturing facilities were operating at about 65% utilisation in H1 FY27, including 15% to 20% of available capacity used for new-product introductions, prove-outs and customer qualifications. Management said it would initiate capacity expansion if customer demand required it and was evaluating an equity fundraise in early calendar 2027, subject to final requirements and market conditions.

Outside the existing facilities, the Saudi Arabia joint venture with Kanoo was targeting commercial manufacturing readiness in March or April 2027. Hobel's Vizag facility was pursuing AS9100 certification with completion targeted for February 2027, which management said could open aerospace bellows opportunities.

Conclusion

Unimech's Rs 855 crore order book and qualification pipeline point to management's effort to add multi-year component revenue alongside its short-cycle tooling business. The H1 FY27 mix, where tooling supplied 67% of Rs 231 crore revenue and PCA supplied 33%, shows that the legacy activity remains the principal contributor even as long-term programmes are being developed.

The next milestones are December 2026 commissioning of the special-process capacity, the February 2027 AS9100 target for Hobel's Vizag facility and the March 2027 Nadcap target. Management also expects H2 FY27 revenue to be higher than H1 with similar margins, contingent on semiconductor deliveries, nuclear-order execution, qualifications and customer production schedules.
