E-mail: investor.relations@ril.com, Website: www.ril.com CIN- L17110MH1973PLC019786 MEDIA RELEASE Reliance Industries and Rolls-Royce announce strategic intent to partner and develop India's indigenous combat engine for the Advanced Medium Combat Aircraft (AMCA) programme London / Mumbai, 14th August 2026: Reliance Industries Limited (Reliance) and Rolls-Royce (LSE: RR., ADR: RYCEY) today announced their strategic intent to partner and offer capabilities for the design, development, manufacturing and delivery of a sovereign indigenous combat engine for India’s Advanced Medium Combat Aircraft (AMCA) programme. As part of the partnership, Reliance and Rolls-Royce will explore the formation of a dedicated Aerospace Gas Turbine Complex that will be a centre of excellence for power and propulsion technology in India. The partnership will offer a compelling proposition for joint development of the AMCA engine in India, bringing together world-leading technology and industrial execution capabilities. This marks a step towards realising the vision set out by the Hon’ble Prime Minister of India, Shri Narendra Modi, for India’s defence ecosystem to deliver an indigenous engine to power the country’s fighter jet programme. Statement from Sh Anant Ambani, Executive Director, Reliance Industries Limited: "India’s strategic autonomy requires sovereign capability in critical technologies. Our intent with Rolls-Royce is to combine their world-leading expertise in advanced propulsion with Reliance’s technology, manufacturing, scale and execution capabilities to build an indigenous aero-engine ecosystem in India. Together, we aim to build an enduring national capability that can make India self-reliant and, over time, globally competitive in advanced propulsion technologies. This is our contribution to the Hon’ble Prime Minister Shri Narendra Modi’s vision of an Atmanirbhar Viksit Bharat." Statement from Tufan Erginbilgiç, CEO, Rolls-Royce plc: "I welcome the opportunity to join forces with Reliance Industries, bringing together our century-long heritage in advanced engineering and proven engine expertise with their homegrown leadership in Indian industry. Together, with our existing partnerships and capabilities in India, this marks a major milestone towards building a robust, self-reliant aerospace ecosystem in the country." By combining Rolls-Royce’s global leadership in engines with the established industrial strengths of Reliance, the Aero Gas Turbine Complex will build sovereign, end-to-end Indian capability across design, development, manufacturing, testing, production and through-life support. This will also unlock opportunities to explore wider collaborations across defence, civil aerospace, and new power and propulsion systems. The alliance will support India’s ‘Atmanirbhar Bharat’ vision for technology indigenisation and help position the country as a global leader in advanced propulsion capabilities.
