Top EMS Stocks India (Week of May 10, 2026)

Sector Pulse

The EMS sector currently presents a MIXED demand environment based on the latest constituent disclosures. AIMTRON reported an IMPROVING setup, highlighted by its acquisition of US-based International Control Services Inc. (ICS) to expand its geographical footprint. Conversely, CENTUM reported a MIXED environment, recording a 21.4% year-on-year increase in operational revenue to ₹3,314 Mn, but suffering a consolidated net loss of ₹618 Mn due to discontinued operations and exceptional items.

Catalysts Playing Out Across the Pack

Two primary catalysts are driving the sector: Order Book Or Contract Wins and Value Added Product Mix Shift. Both constituents are actively securing new business. CENTUM reported a consolidated order book of ₹17,001 Mn and secured a major AESA Radar Systems order from HAL worth ₹66 crore for Phase 1 and ₹500 crore for Phase 2. AIMTRON noted a current order book of ₹98 Crores with an RFQ pipeline of ₹155 Crores. Furthermore, both companies are moving up the value chain. AIMTRON is transitioning from a standard EMS model to an ODM-ESDM provider, leveraging the engineering talent from its recent acquisition. CENTUM is entering mission-critical air navigation systems, evidenced by its partnership with GRSE.

What Managements Are Guiding

Forward visibility remains limited across the analyzed constituents. AIMTRON management expects its recent acquisition to support a long-term revenue goal of ₹1000 crore, with the acquired entity contributing up to ₹280–300 crore annually. AIMTRON also guided for a capex of ~INR 10–12 crore to support capacity expansion. CENTUM, however, did not provide quantitative forward revenue or margin guidance, focusing instead on its restructuring efforts. Consequently, the aggregate revenue outlook is constrained by insufficient guidance disclosure.

Shared Risks (9-type taxonomy)

The sector faces active geopolitical and regulatory risks tied to international exposure. CENTUM derives 65-70% of its revenues from overseas customers in advanced economies, exposing it to macroeconomic fluctuations in Europe and the UK. AIMTRON specifically cited potential tariff impacts as a driver for its US acquisition, aiming to mitigate these risks by adding brick-and-mortar operations on US soil. Additionally, litigation risk is highly active for CENTUM, which reported an exceptional item of INR 556 million and is undergoing a judicial reorganization process for its entities in France.

Bottom Line

The sector verdict is CAUTIOUS. While top-line metrics and order books are expanding, the severe bottom-line impact of restructuring and exceptional losses at CENTUM weighs heavily on aggregate profitability. AIMTRON's successful M&A execution and capital raise of ₹945.7 million provide a positive counterweight, but the broader sector's near-term earnings trajectory remains clouded by overseas operational challenges and geopolitical uncertainties.
