Rossell Techsys is a precision manufacturer that builds the electrical nervous systems and electronic brains inside fighter jets, helicopters, satellites and chip-making machines - the wiring harnesses, control panels and test gear that global defence and aerospace giants trust to work every time. It began in 2011 as a greenfield venture to fulfil offset obligations for Boeing in India, and was demerged from its parent Rossell India Limited in August 2024 to become an independent listed company. The recurring approach is a "CEO" philosophy - customer first, employee next, organisation last - that has produced a 100% customer retention rate and a roster of marquee names including Boeing, Lockheed Martin, Honeywell and BAE Systems. # Business segments Four engines at different stages - a defence manufacturing cash cow, two new-growth platforms in space and semiconductor, and an aftermarket services business just getting started - all built on the same precision-manufacturing backbone. ## 1. Aerospace and defence manufacturing: where the company's reputation was forged **This is the core factory floor - building electrical wiring systems, electronic assemblies and automated test equipment for the world's most demanding military and commercial aircraft programmes.** - **Wired into America's fleet** - the company's wiring harnesses, interconnect systems and electrical panels are embedded in over a dozen flagship US military platforms, from advanced fighter jets and attack helicopters to maritime patrol aircraft and multimission naval helicopters. - **Four competencies under one roof** - it designs and manufactures electrical wiring and interconnect systems (EWIS), electronic systems and system integration (ESSI), automatic test equipment (ATE), and electrical panel assemblies (EPA), all certified to the aerospace industry's highest standards. - **Certifications are the entry ticket** - the company holds 45 NADCAP AC7121-audited processes, the highest count in Asia, plus AS9100 Rev D, ITAR compliance, and compliance with US cybersecurity standard NIST SP 800-171, which together make it a qualified supplier that global OEMs can plug into without additional vetting. - **Centres of Excellence lock in customers** - dedicated factory infrastructure and teams are built around individual marquee clients like Boeing and Lockheed Martin, so each customer gets a production line that behaves like an extension of its own operations. - **Awards tell the story** - Boeing named it Supplier of the Year twice in five years (2015 and 2019), the only Indian aerospace company to achieve that; Lockheed Martin gave an Outstanding Supplier Recognition Award, Honeywell gave a Supplier Excellence Award, and BAE Systems gave a Special Recognition Award. ## 2. Space manufacturing: the new frontier that moved from qualification to volume orders **In a single year, the company went from proving it could build for space to winning a landmark multi-year contract worth roughly INR 400 crores.** - **Harnesses that leave the planet** - the company manufactures complex wiring harnesses for satellite payload systems and other components that go into space, applying the same high-reliability manufacturing discipline it uses for military aircraft. - **Qualified, then ramped immediately** - FY26 was the structural shift: the company completed customer qualification and moved straight into volume-ready execution, securing a multi-year space contract and beginning to onboard additional space customers. - **Customers want it closer** - one leading global space customer is actively encouraging the company to expand its US presence through its Arizona subsidiary, Rossell Techsys Inc., so that support can happen nearer to the customer's own operations. ## 3. Semiconductor equipment manufacturing: early leadership in a new supply chain **The company now makes wiring harnesses for the machines that manufacture semiconductor chips - a segment that went from customer qualification to volume ramp-up within the same year.** - **Inside the chip-making machines** - the company produces electrical harnesses for semiconductor manufacturing equipment, a precision-intensive application where reliability directly affects the uptime of multi-million-dollar fabrication tools. - **First-mover advantage** - management describes the company as building "early market leadership" in this segment, having secured assured orders from existing customers and begun onboarding another major overseas semiconductor customer. - **Part of the diversification story** - semiconductor work, together with space, is the engine that management expects will bring defence's share of revenue down from 93% to roughly half over the medium term, reducing dependence on any single sector. ## 4. Aftermarket services (MRO): the repair-and-overhaul business just getting started **With a newly acquired Defence Production License and AS9110 MRO certification, the company can now repair, overhaul and reverse-engineer electrical and electronic systems for military aircraft - a market it is only beginning to pursue.** - **Fixing what it already builds** - the company provides maintenance, repair and overhaul services for electrical and electronic systems, including re-engineering products, developing alternate parts and reverse-engineering entire assemblies when original components are no longer available. - **Certifications unlocked the Indian market** - obtaining the AS9110 MRO certification and a Defence Production License formally unlocked the Indian market for manufacturing, repair, overhaul, and aftermarket services, and the company is evaluating entry into Indian defence and MRO. - **A natural extension** - because the company already knows the systems it built for global OEMs, offering aftermarket support is a logical next step that deepens customer relationships and creates a recurring revenue stream beyond original equipment delivery. # Manufacturing backbone **A single flagship campus in Bengaluru houses all production, engineering and quality functions - and it is expanding fast to absorb the space and semiconductor ramp-up.** - **One integrated campus** - the company operates from a 4.25-acre site in the Hi-Tech Defence and Aerospace Park in Devanahalli, Bengaluru, with a paperless, IGBC Gold-rated facility that integrates engineering, supply chain, quality and sales under one roof. - **Capacity tripling in phases** - from 225,000 sq ft in FY25, the company expanded to 240,000 sq ft, then initiated a further 150,000 sq ft build and leased an additional 210,000 sq ft nearby, taking total capacity to 465,000 sq ft with the leased facility chosen for faster operational readiness. - **Raw materials are the big cost** - materials account for 50-60% of revenue, and almost 80% of raw materials are imported, so the company is localising sourcing where possible and adding price-adjustment clauses to new long-term contracts to protect against currency and commodity swings. # Group structure and partners **A lean corporate structure with a single US subsidiary that acts as the near-shore arm for American customers, plus a board and leadership team with over 360 man-years of industry experience.** - **Parent and subsidiary** - Rossell Techsys Limited is the listed Indian parent, headquartered in Bengaluru; its wholly owned subsidiary Rossell Techsys Inc. operates from a 4,000 sq ft leased facility in Tempe, Arizona, with five employees providing near-shore support in repairs, supplier quality, logistics and business development for US customers. - **Built at the customer's request** - the US subsidiary was formed at the behest of key American customers who wanted local support, and its role has since expanded to include on-site quality, licensing-related services and institutional collaborations. - **Marquee partnerships spanning a decade** - Boeing, Lockheed Martin, Honeywell and BAE Systems are the anchor customers, each with relationships evidenced by multiple supplier awards and dedicated Centres of Excellence within the Bengaluru factory. - **Leadership continuity** - the board is chaired by Harsh Mohan Gupta with Rishab Mohan Gupta as Managing Director, supported by a CEO, CFO and COO who together with the senior team bring over 360 man-years of combined experience from large global corporations.
