Centum Electronics is a builder of the electronic brains inside India’s most sensitive machines - missiles, satellites, fighter-jet radars - and a quiet manufacturing partner to global industrial giants who need their own complex electronics made without fail. Founded in Bangalore in the early 1990s, it spent three decades moving from design services into full-blown, turnkey manufacturing of mission-critical systems, a journey that made it one of the largest private suppliers to ISRO and a trusted factory floor for Western semiconductor and defence OEMs. The recurring approach is simple: it inserts itself so deeply into a customer’s supply chain - as a single-source supplier for roughly 80% of what it makes - that walking away becomes almost impossible, then it climbs the value chain from making components to owning the design of entire systems.
Business segments
Three engines, one platform - a turnkey systems builder for Indian defence and space, a high-reliability contract manufacturer for global OEMs, and a deep bench of 600 design engineers that feeds both - all recently refocused on a pure India-based ESDM core after exiting loss-making overseas adventures.
1. Build-to-Specification: where India’s defence and space programmes get their electronic systems
Centum takes a customer’s concept for a radar, satellite payload or missile subsystem, designs it, industrialises it and manufactures the finished system - owning the entire chain under one roof.
- Turnkey from concept to deployment - the company works on a Build-to-Specification model, meaning a defence lab or ISRO hands over a requirement and Centum delivers a qualified, field-ready electronic system, with a single point of accountability for design, testing and production.
- The moat is a top-tier security clearance - it holds a SAMAR Maturity Level 5 certification, the highest level, which lets it bid for the most sensitive defence tenders covering safety-critical and mission-critical projects, a filter that shuts out most competitors.
- Radars are the new frontier - having supplied modules and subsystems for decades, the company recently won a marquee order from HAL for a full AESA radar on the UHM platform, a program worth over INR 570 crores across its lifecycle, and a second order for a complete satellite-and-debris-tracking radar system, marking a deliberate climb from component-maker to system-owner.
- Space is the long-standing backbone - since 2002 it has delivered mission-critical electronics on almost every major ISRO mission, including Mangalyaan, Chandrayaan and Aditya-L1, typically supplying 300 to 500 components per mission, and in FY24 it won a roughly INR 200 crore order for defence satellite payloads.
- Sticky, multi-decade customer ties - the average relationship with its top customer groups spans 10 to 15 years, and the BTS order book stood at approximately INR 864 crores at the end of FY26, having grown at a compound rate of about 20% over the preceding three years.
2. Electronic Manufacturing Services: the high-reliability factory for global OEMs
When a semiconductor equipment maker or an industrial giant needs complex circuit boards and box-level systems built to exacting standards, Centum acts as their outsourced production line - assembling, testing and integrating on a per-unit fee.
- Paid per unit, not per project - unlike the turnkey BTS business, EMS revenue comes from manufacturing service contracts on a cost-plus basis, with margins typically in the 9-11% range, making it a volume-driven engine that contributed 72% of standalone revenue in FY26.
- A semiconductor equipment OEM is the anchor client - the business is riding a wave of global supply-chain diversification toward India, with a leading semiconductor equipment maker deepening its engagement and ramping up deliveries through Centum’s lines.
- More than 80 new products introduced in a year - the EMS division completed over 80 New Product Introductions in FY26 alone, a measure of how quickly it converts customer designs into manufacturable products and wins follow-on business.
- Single-source supplier to most customers - roughly 80% of the products Centum manufactures are single-sourced, meaning the customer has no second supplier, which creates deep integration and high switching costs.
- A global supply chain behind the factory floor - the company draws on a network of over 600 suppliers worldwide to feed its assembly lines, while continuously adding new production capacity and process automation to handle growing orders from industrial electrification and grid-automation customers.
3. Engineering R&D Services: the design brain that feeds both engines
A 600-engineer-strong design force spread across India, Europe and North America that conceives the electronics, embedded software and power systems - then hands the blueprint to the BTS or EMS factory next door.
- The front-end of the “Concept to Commissioning” promise - ER&D teams work on electronic hardware, embedded software, FPGA design, analogue, RF systems, and power electronics, letting customers start with a napkin sketch and end with a manufactured product inside the same company.
- Flexible engagement, fixed-price delivery - projects often begin on a time-and-materials basis and convert to fixed-price contracts once the scope is clear, giving customers early flexibility and Centum a path to higher-value, outcome-based work.
- Proprietary products have spun out of the lab - the division developed its own Public Address and Passenger Information Systems for trains, deployed across North America, Europe, Asia and Australia, and has engineered electric-vehicle inverters, battery management systems and hydrogen-fuel-cell electronics.
- Cross-selling is the structural glue - the EMS and Strategic Electronics divisions’ strategy explicitly targets feeding ER&D services to their customers, so a customer who comes for manufacturing often stays for design, and vice versa.
Group structure and partners
Centum has just completed a brutal two-year clean-up of its international structure - shutting down loss-making Canadian operations and exiting its French subsidiary through a court-supervised sale - to refocus entirely on its profitable Indian ESDM platform, while locking in strategic partnerships with global defence houses.
- The French subsidiary was the biggest drag - Centum T&S Group S.A., a designer of embedded systems for transportation and aerospace with sites in Paris, Grenoble, Toulouse, Lyon and Belgium, had eroded its net worth to negative INR 1,804 million by FY26; in June 2026 a Lyon court approved a restructuring plan under which MBDA France and SII acquired the business with no consideration flowing back to Centum, and the parent wrote off investments and receivables totalling over INR 1,900 million.
- Canadian operations were discontinued outright - two fourth-level subsidiaries supplying passenger information systems to train builders like Alstom and Siemens were consistently loss-making; the board approved winding them up in December 2025, after providing INR 504 million against trade receivables and advances.
- The Indian subsidiary was absorbed - Centum T&S Private Limited, the domestic ER&D arm, was merged into the parent company with effect from the appointed date of April 1, 2024, with the scheme approved by the board in August 2024 and by the NCLT in October 2025, and effectiveness pending filing of the order with the Registrar of Companies, simplifying the group structure to a single listed entity.
- Global defence partnerships are the new growth playbook - Centum has signed exclusive MoUs with Spain’s Indra for long-range space-surveillance radar, with Israel’s Rafael for electronic warfare systems for the Indian Navy and Coast Guard, with Bharat Electronics Limited for EW and radar, with Garden Reach Shipbuilders for naval navigation systems, and with Indra Air Traffic for air navigation systems, each aimed at co-developing and indigenous manufacturing under India’s Atma Nirbhar Bharat framework.
