Same Industry, Different Economics: How to Compare Two Companies

Put two companies from the same industry beside each other and the comparison seems straightforward. Who is growing faster? Who has the higher margin? Which share trades at the lower multiple?

Those are useful questions. They become much more useful once we understand what sits behind the numbers.

Two retailers can sell similar products while one owns its stores and the other leases them. Two manufacturers can earn the same profit while one waits much longer to collect payment. Two technology-service businesses can serve the same customer industries but do different work, with different staffing needs and contract risks.

The industry tells us where to begin. It does not tell us how each business earns its return.

First, make sure the columns belong together

TCS and Infosys are a useful place to practise. There is a timing trap before we even reach the figures.

As of 13 October 2026, TCS has published its September-quarter results, on 8 October. Infosys’s investor calendar in its FAQs lists 23 October as the tentative release date for that quarter. Comparing each company’s “latest quarter” would put different periods together.

For a matched comparison, start with the quarter ended 30 June 2026. Here are selected figures from TCS’s July release and Infosys’s July release:

Revenue is on a common period and currency basis. The other rows need more work. TCS qualifies its headline margin by excluding an exceptional item. The cash highlights also use different measures: operating cash flow and free cash flow are not interchangeable.

The table is a starting point for questions, not a ranking. The apparent 2.9-percentage-point margin gap does not, on its own, establish a lasting competitive advantage. Before using it, reconcile adjustments and examine several periods on a consistent basis.

Keep reported growth separate from constant-currency growth too. The former includes translation effects; the latter attempts to remove them. Neither label should disappear when the number moves into a spreadsheet.

Ask what the customer is actually buying

“Both are in IT services” is not yet an explanation of their economics.

For any pair, I would map the work: recurring operations, consulting, implementation, engineering or a product licence. Then I would ask how it is priced. Charging for time, accepting a fixed project price and being paid for an outcome create different ways to make—or lose—money.

A fixed-price project can become more profitable when delivery gets faster. It can also become painful if the original estimate was wrong. A time-based contract has a different relationship between hours worked and revenue earned.

These are possible mechanisms to investigate, not claims that explain the TCS–Infosys margin difference. To make that claim, we would need evidence about their actual mix, delivery costs and contract terms.

The same exercise works elsewhere. A retailer selling its own brands is not doing exactly the same job as a distributor of other people’s products. A manufacturer with scarce technical capability has a different bargaining position from one competing mainly on price.

A margin tells us only part of the return

Suppose two fictional suppliers each generate ₹100 crore of annual revenue.

Company A earns a 20% operating margin, producing ₹20 crore of operating profit. Company B earns 15%, producing ₹15 crore. On margin and profit alone, A looks stronger.

Now add the capital needed to support those sales. A uses ₹100 crore; B uses ₹50 crore. In this simplified example, their pre-tax operating returns on that capital base are 20% and 30%, respectively.

B earns less profit from the same sales, but more profit per rupee of operating capital. That distinction matters when the companies have opportunities to expand.

SAME SALES. DIFFERENT CAPITAL NEEDS.

The higher margin doesn’t settle it.

Two fictional suppliers each sell ₹100 crore a year. Company A stays fixed at a 20% margin and ₹100 crore of operating capital. Change Company B, then see what growth requires from both.

Scroll the table sideways to compare both companies.

Annual figures; rupee amounts in crore

Measure	Company A	Company B
Revenue	₹100.00	₹100.00
Operating margin	20%	15%
Operating profit	₹20.00	₹15.00
Operating capital base	₹100.00	₹50.00
Capital turnover	1.00×	2.00×
Pre-tax operating return	20.0%	30.0%
Extra sales at 20% growth	₹20.00	₹20.00
Extra annual operating profit	₹4.00	₹3.00
Extra operating capital needed	₹20.00	₹10.00

B’s 30.0% operating return exceeds A’s 20.0%. At 20% growth, B needs ₹10.00 crore of extra capital for ₹3.00 crore of extra annual operating profit.

Follow the capital calculation

B’s operating profit: ₹100 crore × 15% = ₹15.00 crore. Capital turnover: ₹100 crore ÷ ₹50 crore = 2.00×. Operating return: ₹15.00 crore ÷ ₹50 crore = 30.0%. Growth adds ₹20.00 crore of sales; keeping turnover constant requires ₹10.00 crore more capital. Margin and turnover are assumed unchanged during expansion.

Choose “Higher margin, more capital.” B’s margin rises to 25%, but its capital base rises to ₹150 crore. Its modeled operating return falls to 16.7%, below A’s 20%.

Then try “More capital tied up.” B keeps its original margin, but needs twice the starting capital. Its return falls from 30% to 15%. In a real business, slower collections or heavier inventory could be among the reasons capital requirements rise; this example does not model either cause separately.

The arithmetic is simple:

Operating profit ÷ operating capital = operating margin × revenue ÷ operating capital.

The harder work is deciding what belongs in the capital base. Cash surplus to operating needs, goodwill, leases and unusual balance-sheet items can change the comparison. Use a consistent definition and, where appropriate, average balances. The interactive figures are a teaching proxy, not reported ROCE for either real company.

Follow the money after the sale

A sale can be profitable before it has been paid for. If customers take longer to pay, receivables rise and more money stays inside the business.

That does not make every increase in receivables a warning. Growth can require working capital. Seasonality can move collections between quarters. A large project may have agreed payment milestones. The question is whether the extra capital produces worthwhile returns and whether collection assumptions are credible.

Read the cash-flow statement alongside profit over several years. Compare similar cash measures, reconcile how free cash flow is calculated, and investigate large changes in receivables, inventory and supplier payments.

Also look for trade-offs. Delaying supplier payments can improve cash today without improving the product or customer relationship. Cutting investment can flatter a cash figure while weakening the business later.

Growth has a funding requirement

In the starting interactive example, both suppliers grow sales by 20%. Holding margins and capital turnover constant, A needs ₹20 crore of extra operating capital for ₹4 crore of extra annual operating profit. B needs ₹10 crore for ₹3 crore.

Those figures describe different reinvestment requirements. They are not free-cash-flow forecasts: operating profit is before interest and tax, and the model does not include maintenance investment or the timing of payments.

The assumption deserves scrutiny too. Spare capacity might allow growth with little immediate investment. Entering a new market might require a much larger commitment before sales arrive. Historical returns do not guarantee the same return on the next rupee invested.

A better business can still be an expensive share

Once the operating comparison makes sense, bring in valuation.

A premium may be reasonable for durable returns, reliable cash generation or a long runway to reinvest. It can also leave little room for disappointment. A lower multiple may compensate for weaker economics—or reflect a problem the simple peer table has missed.

Keep the basis consistent here too. An equity earnings multiple is affected by financing and tax; an enterprise-value multiple uses a different claim on the business. Debt, leases and surplus cash need coherent treatment. A bank, in particular, needs a framework suited to funding, credit risk and regulatory capital rather than a supplier-style operating-capital shortcut.

I would finish a comparison with five short answers:

1. What does each customer pay for, and why? Identify the work, pricing and repeat-purchase reasons.
2. Where does the margin difference come from? Separate business mix, execution and accounting adjustments.
3. How much capital supports the profit? Use consistent definitions and explain material differences.
4. What does growth require? Test cash collection, reinvestment and the economics of new business.
5. What is already expected in the price? Consider what has to go right, and what could go wrong.

A good comparison should make each company easier to understand. It should explain why two businesses sharing an industry label can produce different outcomes—and identify the evidence that would change that explanation.
