The transaction, valued at approximately GBP 11.89 million (approximately INR 153 crore), is expected to close by end July 2026, subject to customary closing conditions. The transaction represents an enterprise value to adjusted EBITDA (CY2026 estimate) multiple of approximately 4.6x, reflecting Sigma’s disciplined approach towards value-accretive strategic acquisitions. Creating a global precision manufacturing platform The acquisition marks a significant milestone in Sigma's international growth strategy, strengthening its position within the Rolls-Royce supply chain while complimenting its UK division, Nasmyth Group. Bromford's capabilities directly complement Sigma’s expertise in manufacturing larger components for the same OEM customers, giving the combined platform a deeper full-range product offering for global aerospace and power generation customers. In addition, Bromford brings new product offerings through long term contracts to manufacture components such as engine lock plates which compliment the larger structural components manufactured by Sigma. Founded in 1988, Bromford operates from its facility in Leicestershire, UK, and specialises in manufacturing complex aeroengine ring components and other complex precision-machined aeroengine structures such as compressor casings, ducts, brackets, and lock plates. Bromford is an operationally profitable business, with demand from key customers driving the growth of the business. Value creation plan Sigma intends to apply the operational playbook used at its other overseas operations to create sustained value at Bromford over the next few quarters, through three initiatives: Margin expansion: Targeting an EBITDA margin improvement through capital investment and automation. India-based manufacturing: Transitioning select component manufacturing to India, mirroring the existing Sigma model to optimise costs and enhance competitiveness, to drive margin expansion. Revenue growth: Achieving revenue growth through deeper penetration with leading OEM customers and expansion of long-term agreements. Bromford's experienced management team will continue to lead day-to-day operations, supported by the broader Sigma leadership team. Commenting on the acquisition, Sunil Kalidindi, Chief Executive Officer, said, "This acquisition strengthens Sigma's position within one of the most demanding aero engine supply chains in the world. Bromford brings precision manufacturing capability that complements us directly, and together the enlarged group creates one of the most capable ring and casing manufacturing platforms globally. We look forward to building on Bromford's three decades of engineering heritage as part of Sigma's broader platform." Through strategic acquisitions, advanced manufacturing capabilities and cross-border integration, Sigma is steadily evolving from an India-based precision engineering company into a globally integrated aerospace and defence platform. With operations spanning India and the UK, the company is creating a differentiated manufacturing ecosystem that supports leading international customers across aerospace and defence, while strengthening India’s role in the global supply chain.
