The automobile industry is changing rapidly.

Electric vehicles, hybrids, connected cars, advanced electronics and autonomous-driving technologies are changing what goes inside a vehicle. This transformation creates opportunities for some auto ancillary companies—but it could also make some traditional suppliers less relevant.

For investors, this creates an important question:

How do you identify an auto ancillary company that can remain relevant over the next 5–10 years?

Looking only at revenue growth or the share price is not enough.

A better approach is to ask a structured set of questions about the company’s products, customers, management, EV strategy, financial performance and valuation.

Here are 10 questions that can be asked for almost any auto ancillary company.

1. What does the company manufacture?

This should be the first question.

Before looking at the stock price, understand the actual business.

Find out:

• What components does the company manufacture?
• Which products generate most of its revenue?
• Are these components mechanical, electrical or electronic?
• Are they used in two-wheelers, passenger vehicles, commercial vehicles or tractors?
• Are the products used in ICE vehicles, EVs, hybrids or all of them?
• Are these low-value commodity products or technologically complex components?

This question tells us what the company actually sells.

More importantly, it helps us understand whether its products will remain relevant as automobile technology changes.

The key question

Will the products this company makes today still be required 10 years from now?

2. Who are its biggest customers?

An auto ancillary company is often heavily dependent on automobile manufacturers.

Therefore, we need to understand who is buying its products.

Look at:

• Major OEM customers
• Percentage of revenue from the largest customer
• Top five customer contribution
• Domestic vs international customers
• Passenger vehicle vs commercial vehicle vs two-wheeler exposure
• EV vs ICE customers

Customer quality matters.

A supplier working with several large global OEMs may have a different risk profile from a company dependent on one small manufacturer.

The key question

If the company’s biggest customer loses market share, what happens to the supplier?

3. How dependent is the company on ICE vehicles?

This is becoming one of the most important questions.

ICE means Internal Combustion Engine, which includes traditional petrol and diesel vehicles.

Some auto ancillary products are highly dependent on the internal-combustion engine.

If EV adoption increases, demand for those components could decline.

Therefore, investors should identify:

• ICE-dependent revenue
• EV-compatible revenue
• Hybrid revenue
• Powertrain-neutral revenue

Then ask:

What happens to this company’s business if EV adoption becomes much faster than expected?

A company doesn’t necessarily need to become a pure EV company.

A better position could be having products that work across:

ICE + Hybrid + EV

4. What percentage of revenue comes from EV-related products?

This question separates EV storytelling from EV business.

Many companies say:

“We are preparing for EVs.”

But that statement doesn’t tell us much.

Instead, look for numbers.

Ask:

• What percentage of revenue comes from EV products?
• How much did EV revenue grow last year?
• Is EV revenue growing faster than total revenue?
• How many EV customers does the company have?
• How many EV programmes has it won?
• What percentage of its order book is EV-related?

For example:

Company A

EV revenue = 2%

Management says EV is the future.

versus:

Company B

EV revenue = 35%

EV revenue growing 40% annually.

The second company gives investors much more evidence that its EV strategy is actually working.

5. When did management start preparing for EVs?

Timing matters.

A company that started preparing for EVs five or ten years ago may have a significant advantage over one that has only recently announced an EV strategy.

Look through old annual reports and investor presentations.

Ask:

• When was EV first mentioned?
• When did management identify electrification as a strategic opportunity?
• When did R&D begin?
• When were the first EV products developed?
• When did the company receive its first EV order?
• When did EV revenue start appearing?

This is also a good way to test management credibility.

Compare:

What management said five years ago

with

What actually happened five years later.

The key question

Did management foresee the transformation, or is it simply reacting to it now?

6. What actual investments has management made in EVs?

This is perhaps the most important question.

Don’t judge a strategy by presentations.

Look at where the company is putting its money.

Check for:

• R&D spending
• New manufacturing plants
• EV production lines
• Technology acquisitions
• Joint ventures
• Technology partnerships
• New engineering centres
• Hiring of specialised talent
• New EV product development

There is a huge difference between:

“We plan to enter the EV market.”

and:

“We invested ₹500 crore in a new facility, developed three EV products and already secured orders from five customers.”

The second statement is backed by action.

7. Are those investments generating revenue and orders?

Investment alone isn’t enough.

A company can spend enormous amounts of money on a new technology without generating meaningful returns.

Therefore, follow the chain:

Investment

↓

Product development

↓

Customer approval

↓

Orders

↓

Production

↓

Revenue

↓

Profit

This is the complete journey.

Ask:

• How many new programmes have been won?
• What is the order-book value?
• How much of the order book is EV-related?
• When will those orders start contributing revenue?
• Are new customers being added?
• Is capacity utilisation increasing?

The key question

Is the company’s EV investment becoming a real business, or is it still only a future promise?

8. Is the company’s financial performance improving?

Eventually, every strategy has to appear in the financial statements.

Look at at least five years of:

• Revenue
• EBITDA
• EBITDA margin
• PAT
• EPS
• ROCE
• ROE
• Operating cash flow
• Free cash flow
• Debt

Don’t look at revenue alone.

A company may grow revenue by 30% but increase profit by only 5%.

That could indicate:

• Margin pressure
• Higher raw-material costs
• Poor product mix
• Higher expenses
• Aggressive pricing

Therefore, ask:

Is the company growing profit and cash flow along with revenue?

9. What could make the company lose its competitive advantage?

This is the question investors often forget.

When researching a company, it is easy to focus on why it will succeed.

Instead, deliberately search for reasons why it could fail.

Ask:

Technology risk

Could a new technology make its products obsolete?

Customer risk

Could its largest customer reduce orders?

Competition

Can another company manufacture the same product more cheaply?

Chinese competition

Could Chinese manufacturers put pressure on prices?

EV transition

Could EV adoption happen faster than the company can adapt?

Management

Can management execute its expansion plans?

Debt

Has the company borrowed too much to fund expansion?

Capital allocation

Is management investing shareholder money wisely?

The objective isn’t to find a company with zero risks.

Such a company probably doesn’t exist.

The objective is to understand:

What could break the investment thesis?

10. At the current valuation, how much future growth is already priced into the stock?

This is the question that connects business analysis with investment returns.

A great company doesn’t automatically mean a great stock investment.

Suppose a company is growing earnings at 25% annually.

Sounds excellent.

But if the stock is trading at 80× earnings, investors may already be expecting years of 20–25% growth.

If growth falls to 10–12%, the share price could suffer even though the company continues to grow.

Therefore, compare:

Current market capitalisation

with:

• Current revenue
• Current profit
• EPS
• Expected earnings growth
• P/E
• EV/EBITDA
• ROCE
• Free cash flow

Then ask:

What growth rate does today’s valuation appear to be assuming?

This is one of the most important questions in the entire framework.

The Auto Ancillary Investor Checklist

After answering all 10 questions, create a simple scorecard.

The Most Important Question

If you remember only one question from this entire framework, make it this:

“If the automobile industry looks completely different 10 years from now, will this company be more relevant or less relevant?”

That question forces us to look beyond today’s financial statements.

An auto ancillary company may be extremely profitable today because of ICE vehicles.

But if its products become irrelevant in an EV world, today’s profitability may not tell us much about tomorrow.

On the other hand, a company that is successfully moving from traditional components into EVs, electronics, software, sensors and other higher-value technologies may have a much larger opportunity ahead.

From Company Story to Investment Thesis

The ultimate objective of this framework is not to find companies that simply talk about EVs.

It is to identify companies where the following chain is visible:

Good product

↓

Strong OEM customers

↓

Management sees industry change

↓

Investment in future technology

↓

New products

↓

Customer wins

↓

Growing order book

↓

Revenue growth

↓

Profit & cash-flow growth

↓

Reasonable valuation

When most of these pieces fit together, we may have a company worth researching more deeply.

But there is one final rule:

Never confuse a good business with a good stock at any price.

The business tells us what the company could become.

The valuation tells us how much we are paying for that possibility.

That is why the final question—“How much future growth is already priced into the stock?”—is just as important as understanding the company’s EV strategy.
