Unimech Aerospace acquires Hobel Bellows in 2026 deal

What Unimech announced under SEBI Regulation 30

Unimech Aerospace and Manufacturing Limited disclosed a press release under Regulation 30 of the SEBI (LODR) Regulations, 2015, around its latest acquisition move. The company said it signed definitive agreements on April 22, 2026, to acquire Hobel Bellows. Hobel Bellows is described as a specialised manufacturer of metallic bellows and precision-engineered assemblies. The announcement places the acquisition within Unimech’s broader capability expansion plan. The company positioned the deal as a step aimed at long-term value creation, without sharing transaction consideration in the provided text. The development comes alongside a series of disclosures by the company under the same regulation framework.

Target company profile: Hobel Bellows and its facility

Hobel Bellows operates out of a 180,000 sq. ft. facility in Visakhapatnam, according to the release. The company reported revenues of ₹123.7 crore for the year ended March 31, 2026. Unimech also noted that about 90% of Hobel Bellows’ business is export-oriented. That export skew is a key operational detail because it signals customer reach outside India. The provided disclosure does not detail customer concentration, profit metrics, or order book for Hobel Bellows. It also does not mention regulatory approvals, closing timelines, or whether the acquisition is structured as a share purchase or asset purchase. Still, the operational footprint and revenue scale were clearly stated.

Why Unimech wants this asset

Unimech said the acquisition enhances its capabilities in metal forming, welding, and precision fabrication. The company also said it expands its presence in locomotive, industrial, and power sectors. This is notable because it broadens the end-market mix beyond the company’s aerospace and defence positioning. Unimech framed the deal as aligned with its strategy to move beyond precision components into higher-value engineered assemblies and sub-systems. In practical terms, that indicates a shift up the value chain, where suppliers aim to deliver larger, more integrated modules instead of single parts. The disclosure did not quantify expected revenue synergies or margin impact. It also did not provide capex plans linked to the Visakhapatnam facility.

How this fits with Unimech’s recent capacity additions

The acquisition follows several capacity and expansion updates from Unimech over the past months. On December 29, 2025, the company expanded its Precision Engineering Facility at KIADB Aerospace Park, Bengaluru. It added 62,000 sq. ft. to reach a total of 95,000 sq. ft., and said this was funded through internal accruals. The stated objective was to augment high-precision machining capacity and support a growing order book across nuclear, aerospace, and oil and gas sectors. Separately, Unimech also disclosed commissioning two new facilities at the KIADB Aerospace Park in Bengaluru, expanding its total manufacturing footprint to about 243,000 sq. ft. One of these, Unit 3, was described as a 33,000 sq. ft. precision engineering facility focused on high-precision components for Nuclear, Aerospace, and Oil and Gas sectors.

Order wins highlighted in company disclosures

Unimech’s updates also included order announcements that provide context to its operating momentum. On January 7, 2026, Unimech said its wholly owned subsidiary, Innomech Aerospace Toolings, won an order worth ₹72.20 crore from Nuclear Power Corporation of India Limited (NPCIL). The contract is for supplying support equipment to Tarapur Atomic Power Station Units 3 and 4, with staggered deliveries scheduled until December 2028. In another disclosure, Unimech reported an order worth ₹35 crore from an overseas customer for manufacturing and supplying Ground Support Equipment for the aerospace segment. The company said that order is to be executed within 5 to 12 months and clarified it is not a related party transaction, adding that promoters have no interest in the ordering entity.

Stock move linked to Dheya Engineering stake purchase

The company also featured in a market update noting a sharp intraday move in its shares. The report said shares of Unimech Aerospace and Manufacturing Ltd rose nearly 3% on a Wednesday after it approved an investment of up to ₹5.53 crore to acquire a 29.99% stake in Dheya Engineering Technologies. The stock rose as much as 2.74% during the day to ₹968.7 per share, described as the biggest intraday rise since November 10 that year. It later pared gains to trade 1.3% higher at ₹955.3 per share. The same update compared this with a 0.36% advance in the Nifty 50 as of 9:30 AM. The provided text does not state whether this stake purchase is connected to the Hobel Bellows acquisition.

Market impact: what the disclosures indicate

The immediate market reaction described in the provided text relates to the investment to acquire a 29.99% stake in Dheya Engineering Technologies, where shares rose as much as 2.74% intraday to ₹968.7. For the Hobel Bellows acquisition, the disclosure focuses on operational logic rather than near-term financial projections. The key numeric anchors are Hobel Bellows’ ₹123.7 crore revenue base and its 90% export orientation, which could matter to investors tracking export exposure and customer diversification. The capacity additions in Bengaluru, including the stated move to 95,000 sq. ft. for the precision engineering facility and the broader footprint of about 243,000 sq. ft., add context on how Unimech is scaling production. The order wins of ₹72.20 crore and ₹35 crore provide additional data points on demand across nuclear and aerospace ground support equipment segments.

Why this matters for the aerospace and defence supply chain

Unimech’s stated strategy of moving from precision components to higher-value engineered assemblies and sub-systems aligns with a common trend among suppliers seeking deeper integration into customer programs. The acquisition of a specialised metallic bellows and precision assemblies manufacturer can widen process capabilities such as forming and welding, which are often critical in complex assemblies. The mention of locomotive, industrial, and power sectors signals that the company is also positioning for non-aerospace industrial demand. At the same time, the export-heavy profile of Hobel Bellows suggests a business model that is already operating with international customers, which can be relevant for a supplier building global credentials. The disclosures, however, do not provide details on valuation, integration plans, or timelines, so the measurable impact will depend on subsequent filings.

Conclusion

Unimech Aerospace and Manufacturing Limited has signed definitive agreements to acquire Hobel Bellows, adding a Visakhapatnam facility of 180,000 sq. ft. and a ₹123.7 crore revenue business with 90% exports. The company said the acquisition strengthens fabrication capabilities and supports a shift toward higher-value assemblies and sub-systems, while expanding exposure to locomotive, industrial, and power sectors. The deal sits alongside recent Bengaluru capacity expansions and disclosed order wins across nuclear and aerospace ground support equipment. Further clarity is expected only through subsequent Regulation 30 filings that may cover transaction structure, closing conditions, and post-acquisition integration steps.
