A company announces a new factory.

Revenue will increase by 20%.

Management calls it a major growth initiative.

The stock rises.

Most people ask:

“How much will revenue grow?”

A better question is:

“How much money will the company make on the money it is about to spend?”

That question is the foundation of serious investing.

Imagine two companies.

Company A

Company B

Both companies are growing.

Both are expanding.

Both are increasing revenue.

But they are not creating the same value.

Company A earns a 25% return.

Company B earns a 6% return.

Growth is not automatically good.

Growth is only valuable when the returns exceed the cost of capital.

This is the idea that changes how you read almost every annual report.

Many beginners calculate ROE or ROCE and stop there.

Those metrics are useful.

But they describe the business that already exists.

The more important question is:

This is called incremental return on capital.

Suppose a business historically earned 24% returns.

Then it becomes much larger.

Its next investment earns only 10%.

The reported ROCE may still look excellent.

But the future economics of the business have changed dramatically.

Great businesses often become average businesses because incremental returns fall.

Consider a premium consumer products company.

For many years it earned high returns because it expanded into underpenetrated markets.

New products generated strong demand.

Distribution improved.

Scale increased.

Then growth slowed.

Management started investing heavily in:

Revenue continued growing.

But each new investment generated lower returns than earlier investments.

The business was still profitable.

The business was still growing.

But capital efficiency was deteriorating.

This is often invisible if you only look at earnings growth.

When analysing any company, I ask four questions.

Look for increases in:

Not revenue.

Operating profit.

Compare new investment with new profit.

One successful investment is not enough.

The best companies can reinvest at high returns for many years.

That is where extraordinary shareholder value is created.

Imagine two companies each earn $500 million.

One requires almost no additional capital to grow.

The other requires massive reinvestment every year.

The first business can:

The second business is constantly raising capital.

Same earnings.

Completely different economics.

This is why experienced investors often care more about returns on capital than headline earnings.

Here is a useful exercise.

Find the last five years of:

Ask:

“Is each additional dollar of capital producing more profit or less profit?”

That question reveals whether management is becoming a better allocator of capital or a worse one.

The answer is often more important than next year’s earnings forecast.

Use this prompt with any public company annual report.

Notice what we are asking.

Not for a summary.

For an economic judgement.

That is the difference between using AI as a search engine and using AI as an analytical tool.

Open Excel (or Google Sheets) and create a simple five-year table.

Then calculate:

Finally, create a line chart comparing EBIT growth and invested capital growth.

The objective is not the formula.

The objective is to visually identify whether the company is becoming more capital efficient or less capital efficient.

A useful formatting rule:

This is the same discipline used in professional investment banking and equity research models.

Choose a company you know.

Find:

Then answer:

“If this company invested another $100 million next year, do I believe it could earn more than a 15% return on that investment?”

Do not worry about getting the exact number.

Focus on the reasoning.

Because the future value of a business is determined by the return on capital that has not yet been invested.

Choose one listed company and spend 15 minutes answering these questions.

Write a three-sentence investment memo:

“This company appears to be creating / destroying shareholder value because…”

The constraint is important.

Analysts are often forced to make decisions with incomplete information.

Learning to communicate a conclusion clearly is as valuable as building the calculation itself.

Next week, we will examine a metric that looks impressive in almost every investor presentation but often hides operational weakness: EBITDA.
