India’s electronics exports have surged at an extraordinary pace. In just over a decade, export volumes have expanded nearly eight times, marking one of the most decisive shifts in the country’s manufacturing story. At the heart of this rise sits a quiet but powerful engine: Electronics Manufacturing Services, or EMS.
The growth numbers appear impressive, but beneath the surface, the EMS business reveals a far more complex and fragile reality. Recent slowdowns among India’s largest EMS players signal that this industry, despite its scale, operates under tight constraints. Understanding this slowdown requires a closer look at how the EMS model actually works.
Where EMS Fits in the Global Electronics Chain
The global electronics industry is not a single factory-driven system. It is a long, fragmented value chain dominated by specialization.
At one end are component manufacturers. Semiconductor chips are designed in advanced innovation hubs and fabricated in capital-intensive facilities across Taiwan, South Korea, and the United States. Displays originate largely from China and Korea. Japanese firms dominate passive components such as capacitors and resistors. Batteries, sensors, camera modules, and connectors are sourced from tightly integrated East Asian ecosystems.
At the opposite end are global consumer brands. These companies control product design, pricing, branding, distribution, and customer ownership. They define what gets built and where it is sold.
EMS companies exist between these two poles. They neither own product designs nor control customer relationships. They do not manufacture advanced components. Their role is execution—turning finalised designs into large volumes of fully assembled products with minimal defects, on strict timelines, and at the lowest possible cost.
This position in the middle is structurally weak. Pricing power is limited. Intellectual property belongs elsewhere. Component sourcing is often dictated externally. As a result, EMS players capture only a small fraction of the total value created in the electronics ecosystem.
This imbalance is well described by the “Smile Curve,” where value concentrates at the design and branding stages, while assembly remains trapped at the bottom. EMS businesses operate permanently in this low-margin zone.
Not All EMS Is the Same
Despite sharing a position in the value chain, EMS work varies widely.
High-volume, low-mix manufacturing dominates public perception. This includes smartphones, laptops, and consumer electronics produced in massive quantities with limited variation. Competition here is intense, margins are thin, and switching costs are low.
At the other extreme lies low-volume, high-mix manufacturing. Automotive electronics, defense systems, industrial controls, and medical devices fall into this category. Volumes are smaller, but complexity is higher. Product lifecycles are longer, certifications are strict, and supplier switching is expensive. These factors create entry barriers and support better margins.
The difference between these two segments defines profitability across the EMS industry.
How EMS Operations Actually Work
EMS execution typically follows two operating models: consignment and turnkey.
In the consignment model, the product owner supplies all critical components. The EMS provider focuses only on assembly and testing, charging a fixed conversion fee. Risk is limited, but so is upside.
In the turnkey model, the EMS company manages sourcing, procurement, inventory, and assembly. This increases responsibility and financial exposure, but also allows higher earnings. The EMS provider effectively becomes both a manufacturer and a short-term financier.
Indian EMS players predominantly operate under the turnkey model. While this expands revenue potential, it introduces severe vulnerabilities. Component price inflation, supply delays, demand shocks, and inventory buildup can rapidly destabilize operations.
These risks directly impact two core metrics: profitability and working capital.
Why Margins Stay Thin
In most electronics products, components account for nearly 70% of the total cost. EMS players pass these costs through with minimal markup. The remaining 30%—covering assembly, testing, logistics, and execution—is where profits are made.
However, pricing power is almost nonexistent. Assembly processes can be replicated, competition is global, and contracts are constantly renegotiated. As a result, net margins rarely exceed 2–4%.
Profitability improves only through scale or complexity.
Scale spreads fixed costs—factories, machinery, power, and labor—across larger volumes. High throughput improves unit economics, but any drop in demand quickly erodes margins.
Complexity, on the other hand, reduces competition. Low-volume, high-mix products command better pricing because they require specialized skills, certifications, and long-term reliability. This segment offers a path away from pure volume dependence.
The Silent Pressure of Working Capital
Margins tell only half the story. Working capital determines survival.
Components are usually paid for within 30–60 days. Production ties up inventory for weeks. Finished goods are shipped, but customer payments often arrive 60–90 days later. This mismatch locks up cash and forces EMS firms to rely heavily on borrowing.
Two companies with identical margins can have vastly different financial strength based on payment cycles and inventory control. Scale improves bargaining power with suppliers and customers, but smaller players struggle to achieve favorable terms.
In rare cases, working capital itself becomes a competitive advantage. Negative working capital cycles—where cash is collected before suppliers are paid—are exceptional in this industry and extremely difficult to sustain.
India’s EMS Push and the PLI Effect
Historically, India entered electronics manufacturing at a disadvantage. Logistics costs were higher, interest rates increased financing pressure, and the component ecosystem was shallow, forcing heavy imports.
The Production Linked Incentive (PLI) scheme directly altered this equation. By offering 4–6% incentives on incremental revenue, the scheme reshaped economics overnight. For businesses operating on 2–3% margins, the impact was dramatic.
Electronics emerged as the largest beneficiary among all PLI sectors, receiving over ₹23,000 crore in incentives. A handful of large players absorbed the vast majority of these payouts. Capacity expansion accelerated, and global brands began reallocating production to India.
However, these incentives are temporary. Mobile manufacturing benefits will expire soon, while structural challenges will persist. Firms that used the subsidy window to build scale, secure supply chains, and deepen customer relationships stand a chance of sustaining growth. Others may struggle once support fades.
A new PLI scheme focused on component manufacturing aims to address deeper ecosystem gaps. Its effectiveness remains uncertain.
What's Next
The EMS industry in India has made undeniable progress. Investment surged, global relevance increased, and manufacturing capabilities expanded rapidly. Yet the fundamental challenge remains unchanged.
Assembly alone is a fragile business. It sits in the weakest part of the value chain, exposed to global competition, margin pressure, and financial stress. Long-term success depends on moving upward—toward design influence, component manufacturing, specialized systems, and deeper integration.
The question is no longer whether India can assemble electronics at scale. The real test is whether it can escape the middle and claim a larger share of value in the global electronics economy.
