## EMS — the story behind the numbers

This is the written read behind the EMS figures above — what is actually happening in the sector, in words, with the evidence each claim rests on. It is dated 22 Jul 2026. 4 themes are live here.

The EMS sector sample for this week consists of a single constituent, AIMTRON, which delivered a transformational FY26. Full-year revenue reached Rs 3,011.6 Mn, representing an 89.2% YoY increase. EBITDA grew 93.6% YoY to Rs 657.7 Mn. The order book surged 175.8% YoY to Rs 5,212 Mn, which is 1.7x FY26 revenue.

How old this read is: This read comes from our EMS sector brief dated 22 Jul 2026, so the words here and the numbers above them cover the same few weeks.

## Revenue Scale & Growth Durability

What the numbers say: Centum Electronics Ltd is the scale leader at ₹1,058 crore, Centum Electronics Ltd's growth is 8.1% from a ₹1,058 crore base, with 15 reported observations in the 20-quarter window. Treat the growth leader as an acceleration candidate, not as equally proven scale.

Investor read: Centum Electronics Ltd is the scale benchmark; Centum Electronics Ltd is the acceleration watch. Promote the challenger only if growth persists and converts into margin and returns.

This conclusion weakens if: Centum Electronics Ltd's growth falls below Centum Electronics Ltd's for two consecutive comparable reports while operating margin also compresses.

Evidence: Centum Electronics Ltd · ₹1,058 crore | Not enough peers | 4/8 recent comparable periods | 1/2 companies · 21 observations

Definition: Revenue is compared on a common reported-currency basis. Growth is year-on-year, so seasonality does not masquerade as progress.

## Operating Economics & Margin Trend

What the numbers say: Aimtron Electronics Ltd leads both opm at 20% and margin change at +1 percentage points.

Investor read: Aimtron Electronics Ltd sets the level benchmark; use the change leader as an inflection watch only after another comparable report confirms it.

This conclusion weakens if: The next two comparable reports reverse the current margin change signal.

Evidence: Aimtron Electronics Ltd · 20% | 66.7% versus #2 · Centum Electronics Ltd | 1/4 recent comparable periods | 2/2 companies · 26 observations

Definition: Operating margin compares operating profit with revenue. Improvement is measured in percentage points, not percentage growth.

### OPM — highest
1. Aimtron Electronics Ltd (AIMTRON): 20%
2. Centum Electronics Ltd (CENTUM): 12%

### Margin change — fastest expanders
1. Aimtron Electronics Ltd (AIMTRON): +1.0 pp

## Profit Scale & Acceleration

What the numbers say: Centum Electronics Ltd leads with ₹50 crore of TTM profit, Centum Electronics Ltd shows ≥100% on the scoring scale (525% uncapped) growth from a ₹50 crore profit base. Compare the size of the base and persistence before ranking acceleration above profit scale.

Investor read: Centum Electronics Ltd sets the level benchmark; use the change leader as an inflection watch only after another comparable report confirms it.

This conclusion weakens if: The next two comparable reports reverse the current profit growth signal.

Evidence: Centum Electronics Ltd · ₹50 crore | Not enough peers | 1/5 recent comparable periods | 1/2 companies · 21 observations

Definition: Net profit is the residual after operating costs, interest and tax. Growth off a loss or near-zero base is excluded from the fastest-grower rank.

### Net profit — largest
1. Centum Electronics Ltd (CENTUM): ₹50 Cr

### Profit growth — fastest growers

## Return On Capital Employed

What the numbers say: Aimtron Electronics Ltd leads ROCE at 28.2%, 2.7 percentage points above Centum Electronics Ltd. Centum Electronics Ltd has the strongest latest improvement at +9 percentage points. Read the leader beside the density of its reported history: a sparse high return is a candidate; a repeated high return is evidence of durability.

Investor read: Aimtron Electronics Ltd sets the level benchmark; use the change leader as an inflection watch only after another comparable report confirms it.

This conclusion weakens if: The next two comparable reports reverse the current roce change signal.

Evidence: Aimtron Electronics Ltd · 28.2% | 10.6% versus #2 · Centum Electronics Ltd | 1/3 recent comparable periods | 2/2 companies · 5 observations

Definition: ROCE asks how much operating return the business earns on the capital employed. Direction matters, but a single exceptional year should not be mistaken for durability.

### ROCE — highest
1. Aimtron Electronics Ltd (AIMTRON): 28%
2. Centum Electronics Ltd (CENTUM): 26%

## Valuation Against Growth & Quality

What the numbers say: There is not enough comparable evidence to name a reliable peg leader.

Investor read: Treat valuation as permission to investigate, never as a standalone reason to buy.

This conclusion weakens if: The next two comparable reports reverse the current p/e signal.

Evidence: No comparable leader | Not enough peers | Not enough history | 0/2 companies · 1 observations

Definition: PEG is shown only when earnings are positive and three-year EPS growth is between 5% and 60%. It is recomputed consistently as the trailing P/E divided by that growth rate — reported earnings, never an expected-earnings multiple. On Indian companies it is shown only where the two data feeds agreed. Where any of that fails the ratio is left out rather than printed: a P/E divided by a loss, or by growth measured off a tiny base, is a number that looks precise and means nothing.

### PEG — lowest PEG

## What can make this comparison misleading?
- A high growth rate can be a low-base artefact. The page keeps level and change separate for that reason.
- A high ROCE can be temporary or flattered by a small capital base. Read it beside margin, cash conversion and reinvestment.
- The 4-Factor Sector Score ranks research priority, not portfolio action. Management quality, catalysts and risks need equally fresh evidence before capital is deployed.
- An “all companies” line chart preserves completeness, but rank changes should be checked against reporting dates before drawing a conclusion.
- 1 company is missing from the second-feed metrics by decision, not by absence: the two sources disagree, so nothing from the second is drawn. Read those rows as narrower evidence, never as a weaker business.
- Thin comparisons: Revenue, Net profit, Valuation have fewer than three usable current readings.

## Source standing of each company

Cross-checked: 1. Unverified: 0. Withheld: 1. Graded companies: 2.

1 of 2 companies has a second data feed that is known to disagree with the primary source, so nothing from it is drawn: Centum Electronics Ltd (CENTUM) — its two data sources disagree by up to 40% on reported income across 14 comparable periods, so its derived ratios are withheld.

### Which EMS company is largest by revenue?

Centum Electronics Ltd leads with revenue of ₹1,058 crore, based on 1 of 2 comparable companies through Jun 2026.

### Which EMS company is growing fastest?

### Which EMS company has the strongest 4-Factor Sector Score?

### How much history does this EMS comparison include?

The page compares up to 20 reported quarters per company for fundamentals, returns and valuation, ending Jun 2026. Missing observations remain blank rather than being estimated.

### How is the 4-Factor Sector Score calculated?

The four visible contributions add directly: growth and earnings up to 35 points, capital efficiency up to 25, valuation up to 20, and relative strength up to 20. Missing or stale evidence moves only the affected contribution toward neutral.

### Is there a Nifty EMS index?

NSE India maintains Nifty indices for several broad sector categories — Nifty Bank, Nifty IT, Nifty Pharma and others — but not for every sub-sector grouping on this site. Whether or not an official Nifty index covers EMS, this page builds its own equal-weight basket of 2 listed EMS companies — one company, one vote, regardless of market value — so no single large company dominates the reading. Figures are as of Jun 2026.

### Which are the best EMS stocks in India?

Ranked by this page's four-factor score, Aimtron Electronics Ltd places first among 2 listed EMS companies, followed by Centum Electronics Ltd. That is a ranking of published data — earnings, quality, valuation and market behaviour as of Jun 2026 — and not a recommendation; Sector Alpha is not registered with SEBI as an investment adviser.

### How many EMS stocks are listed in India?

This comparison covers 2 listed EMS companies in India, each above the size floor the site applies, with 20 quarters of reported figures per company where the filings exist. The full ranked list is on this page, as of Jun 2026.

### Which EMS company is the biggest?

Centum Electronics Ltd is the largest, with trailing-twelve-month revenue of ₹1,058 crore. That covers 1 of 2 companies with comparable reporting through Jun 2026.

### Which EMS company has the best profit margins?

Aimtron Electronics Ltd has the highest operating margin at 20%, from 2 of 2 comparable companies. Aimtron Electronics Ltd shows the biggest recent improvement, at +1 percentage points. A high margin matters most when it is holding or rising, not when it is peaking.

### Which EMS company makes the most profit?

Centum Electronics Ltd earns the most, at ₹50 crore of trailing-twelve-month net profit, from 1 of 2 comparable companies. Centum Electronics Ltd has the fastest profit growth at the ≥100% scoring cap, though growth off a small or recovering profit base overstates how much has actually changed.

### Which EMS company earns the highest return on capital?

Aimtron Electronics Ltd leads on return on capital employed at 28.2%, across 2 of 2 companies. Read it beside the length of its reported history: a high return that repeats for years is evidence of a durable business, while a single high reading can be a small capital base or one good year.

### Is the EMS sector beating the market?

EMS has outperformed NIFTY 500 by 95.8% over the last 52 weeks and 30.9% over 13 weeks, measured on an equal-weight index of its current members. Inside the sector, 2 of 2 covered companies are beating the market on their own. Sector strength does not transfer evenly to every stock in it.

### Which EMS stock has the strongest price momentum?

Aimtron Electronics Ltd has the strongest relative strength against NIFTY 500. Relative strength answers last, after growth, quality and valuation: price can move well before the fundamentals confirm it, and sometimes without them confirming at all.

### Which EMS company scores highest for research priority?

Aimtron Electronics Ltd scores 70.3 out of 100 with 52.8% evidence confidence, from 20.7 points on growth and earnings, 19.6 on capital efficiency, 10 on valuation and 20 on relative strength. This ranks what deserves work next. It is not a buy recommendation, and management quality, catalysts and risk still need separate research.

### How many EMS companies does this comparison cover, and over what period?

It compares 2 listed companies over up to 20 reported quarters of fundamentals, ending Jun 2026, plus weekly price and relative-strength history. Membership is the full sector list — nothing is dropped for having thin data.

### What is the total market cap of the EMS sector?

### Why are some values on this page blank?

A blank means that company did not report a comparable figure for that period, so nothing is shown. Missing observations are never interpolated, carried forward, or replaced with a similar-looking accounting line, and a company with missing evidence has its research score pulled toward neutral rather than being scored as bad.

### Is this investment advice?

No. Every figure here is a deterministic calculation from reported company filings and market data, published for research. It contains no recommendation to buy or sell any security, does not account for your circumstances, and is not a substitute for advice from a licensed adviser.
