....turing in India. This shift requires Tier-1 partners with strong governance, mature quality systems, and proven programme execution. Nasmyth brings decades of experience shaped within European aerospace supply chains, where it has been directly trained, audited, and developed by leading OEMs to meet demanding quality, compliance, and delivery standards. That experience has embedded deep knowledge of OEM production systems, special process control, and long-cycle programme governance. These capabilities are difficult to replicate quickly and remain limited within the domestic Indian aerospace ecosystem. The acquisition also brings advanced manufacturing capabilities into India, including precision machining of hard metals and superalloys....

...., aerospace-grade fabrication and complex systems integration. Integrating these strengths into Sigma’s Indian platform significantly shortens the timeline to scale high-criticality aerospace and defence manufacturing. This transaction is a cornerstone of Sigma’s international growth strategy, which prioritises disciplined acquisitions to add differentiated capabilities rather than relying only on organic expansion. Building and certifying aerospace-grade special processes can take many years. By acquiring Nasmyth, Sigma effectively advances its strategic roadmap by several years while integrating a business that already operates at global aerospace benchmarks. Together, Sigma Advanced Systems and Nasmyth are well-positioned to bene....
