Sigma Advanced Systems secures £300 million long-term agreement with Rolls-Royce to manufacture and supply aerospace systems

Sigma Advanced Systems has signed a seven-year long-term agreement with Rolls-Royce, marking a steady step forward in its global aerospace journey. The agreement represents a deepening strategic relationship with one of the world’s largest and most respected aerospace OEMs, placing the company at the heart of critical global engineering programs.

The contract is valued at nearly £300 million (i.e., roughly Rs 3800 cr), providing the company with a long-term revenue stream and stronger visibility over future growth.

Under the agreement, Sigma Advanced Systems will supply a wide portfolio of high-precision-engineered, safety-critical components and assemblies for Rolls-Royce’s aerospace programs. This is a program-level partnership delivered through the company’s manufacturing network across India and the UK, reflecting how the company is increasingly operating as an integrated global platform rather than a location-specific supplier.

At its core, the partnership builds on an existing relationship and signals continued confidence in Sigma Advanced Systems’ ability to operate as a globally integrated manufacturing platform. Leveraging its India-UK dual-source model, the company brings together cost-efficient scale in India. With proximity, engineering collaboration, and program alignment in the UK, the company cements its transition from a system player to a more integrated manufacturing partner capable of handling larger work packages.

Beyond immediate business impact, the partnership delivers multi-year revenue visibility through a long-term order pipeline and reinforces Sigma Advanced Systems’ growth in long-duration, high-value aerospace programs.

Sunil Kumar Kalidindi, Chief Executive Officer and Executive Director at Sigma Advanced Systems, said, “This partnership with Rolls-Royce reflects how our strategy is taking shape. It validates the investments we have madein building a connected India–UK platform and our focus on quality, reliability, and long-term partnerships. We see this as an opportunity to deepen our role in global aerospace programs while continuing to scale our capabilities across both regions. We sincerely thank Rolls-Royce for the trust it has placed in us by awarding this long-term agreement.”

As the company expands its global footprint, agreements like this point to a broader transition. Sigma Advanced Systems is steadily moving closer to the core of the aerospace supply chain, taking on larger and more complex roles in programs that demand both scale and precision.
