## Auto Ancillaries - Others — the story behind the numbers

This is the written read behind the Auto Ancillaries - Others figures above — what is actually happening in the sector, in words, with the evidence each claim rests on. It is dated 17 Apr 2026, so the words are older than the numbers. 4 themes are live here, 1 of them rated high severity.

The sector outlook is BULLISH. Despite a one-off labor charge impacting PAT, underlying operating performance is expanding, driven by 100% order book coverage for FY 2028, expanding export shares to 20%, and capacity utilization exceeding 90%.

The Auto Ancillaries - Others sector, represented by TENNIND, is showing an IMPROVING demand environment. TENNIND delivered a 14.7% YoY growth in Value Added Revenue, reaching INR 11,941 million, and a 24.8% YoY growth in EBITDA at INR 2,225 million. The EBITDA margin stood at 18.6% of VAR.

How old this read is: STALE — this read comes from our Auto Ancillaries - Others sector brief dated 17 Apr 2026, about 4 months ago. The page says so rather than dressing it up, and a fresh sector dive replaces it the day it runs.

### Live themes, worst first
- HIGH | Newly notified labour code requiring retrospective statutory benefit calculations. | Management stated this is a one-off spend and underlying margins remain intact. | quoted: "For profit after tax, we had a one-time impact of recently notified labour code, which required us to go back in time to calculate the full impact of statutory benefits as per the new definition." | named for TENNIND
- LOW | Shifts in US trade and environmental policy, including tariff reductions. | Viewed as beneficial due to lower tariffs and a move back toward ICE/hybrid vehicles. | quoted: "New tariff and duty reduction announcements by the US and EU will strongly improve the tailwinds to allow us to grow our exports further." | named for TENNIND
- LOW | Elevated prices of precious metals like platinum, palladium, and rhodium. | Partnering with OEMs to optimize design and reduce precious metal loading. | quoted: "we can actually reduce the amount of platinum, palladium, rhodium loading, so as to still get the benefi" | named for TENNIND
- LOW | Uncertainty regarding potential concessions or timeline pushbacks for CAFE 3 and TREM 5. | Management reports no pushbacks from OEMs, who want to stay ahead for exports. | quoted: "So I think look, there are always rumors on push back etc across CAFE, TREM 5, even BS 7 as you know. But from our standpoint we're not seeing that." | named for TENNIND

## Revenue Scale & Growth Durability

What the numbers say: Tenneco Clean Air India Ltd is the scale leader at ₹5,663 crore, 32.7× the revenue of Kinetic Engineering Ltd. Kinetic Engineering Ltd's growth is 25.4% from a ₹173 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: Tenneco Clean Air India Ltd is the scale benchmark; Kinetic Engineering Ltd is the acceleration watch. Promote the challenger only if growth persists and converts into margin and returns.

This conclusion weakens if: Tenneco Clean Air India Ltd's growth falls below Kinetic Engineering Ltd's for two consecutive comparable reports while operating margin also compresses.

Evidence: Tenneco Clean Air India Ltd · ₹5,663 crore | 32.7× versus #2 · Kinetic Engineering Ltd | 5/5 recent comparable periods | 2/2 companies · 24 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: Tenneco Clean Air India Ltd leads both opm at 16% and margin change at -2 percentage points.

Investor read: Tenneco Clean Air India 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: Tenneco Clean Air India Ltd · 16% | 184.2% versus #2 · Kinetic Engineering Ltd | 2/5 recent comparable periods | 2/2 companies · 29 observations

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

## Profit Scale & Acceleration

What the numbers say: Tenneco Clean Air India Ltd leads with ₹602 crore of TTM profit, 46.3× the profit of Kinetic Engineering Ltd. Tenneco Clean Air India Ltd shows 5.6% growth from a ₹602 crore profit base. Compare the size of the base and persistence before ranking acceleration above profit scale.

Investor read: Tenneco Clean Air India 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: Tenneco Clean Air India Ltd · ₹602 crore | 46.3× versus #2 · Kinetic Engineering Ltd | 3/5 recent comparable periods | 2/2 companies · 24 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.

## Return On Capital Employed

What the numbers say: Tenneco Clean Air India Ltd leads ROCE at 60.8%, 57.2 percentage points above Kinetic Engineering Ltd. Tenneco Clean Air India Ltd has the strongest latest improvement at +19.6 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: Tenneco Clean Air India 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: Tenneco Clean Air India Ltd · 60.8% | 16.8× versus #2 · Kinetic Engineering Ltd | 1/1 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. Tenneco Clean Air India Ltd (TENNIND): 61%
2. Kinetic Engineering Ltd (KINETICENG): 3.6%

## Valuation Against Growth & Quality

What the numbers say: Tenneco Clean Air India Ltd has the lowest comparable PEG at 1.84×. Only 1 of 2 companies have earnings and growth steady enough for the ratio to mean anything, so no broad “cheapest stock” conclusion is defensible unless the current multiple, own-history position and growth durability agree.

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: Tenneco Clean Air India Ltd · 1.84× | Not enough peers | 0/3 recent comparable periods | 1/2 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
1. Tenneco Clean Air India Ltd (TENNIND): 1.8

### P/E — lowest P/E

## 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.
- Thin comparisons: Valuation have fewer than three usable current readings.
