TCS vs Infosys: FY 2025–26 Growth, Margins and AI Revenue

Comparison at a glance

What each business actually sells

TCS and Infosys can compete for the same investor capital or customer budget while producing revenue in different ways. Begin with the contract, customer, unit of sale, revenue-recognition rule and capital required to deliver it.

Use the Customer Churn, Gross Revenue Retention and NRR Calculator to apply these points to your figures.

The gap is structural, not cyclical: TCS’s larger, more diversified delivery base supports its margin lead, while Infosys’s smaller base gives it more room for percentage-point growth if large-deal conversion improves.

Where each company has an edge

Metrics that deserve priority

• Constant-currency revenue growth
• Operating margin and utilisation
• Deal wins and conversion
• Free cash flow and dividends
• Headcount, attrition and revenue per employee

Use at least three years where the business structure has remained comparable. When an acquisition, demerger, listing, accounting change or segment reorganisation breaks the series, rebuild the history from restated disclosures or clearly mark the break.

Build a decision-useful scorecard

Start with four separate layers. First, measure growth quality: identify whether expansion comes from volume, pricing, acquisitions, currency, incentives or a change in reporting perimeter. Second, test unit economics: ask what one additional customer, transaction, vehicle, store, workload or contract contributes after direct costs. Third, inspect capital intensity: include capital expenditure, leases, working capital, depreciation, stock compensation and long-term purchase commitments. Fourth, assess durability: customer concentration, switching costs, regulatory permissions, distribution control and the likelihood that competitors can copy the advantage.

For TCS, the strongest disclosed metric should be paired with the cost or balance-sheet item that makes it possible. For Infosys, apply the same rule. This prevents a fast-growing operating statistic from being presented without the cash, capacity or incentive needed to produce it. It also prevents a mature company’s slower growth from being dismissed when it may be generating superior cash returns.

Create three scenarios rather than one forecast. The base case should use current disclosed trends; the downside case should include margin pressure, slower demand and higher funding or compliance cost; the upside case should require a specific operating improvement. Do not change growth, margin and valuation assumptions independently when they are economically linked. A higher growth assumption often needs more capital, customer acquisition or working capital.

Finally, keep business quality and share price separate. A stronger company can still be a poor investment at an excessive price, while a weaker company can appear statistically cheap because the market expects deterioration. This article does not use live market prices; insert the current price, share count, net debt and dilution only on the date of your own analysis.

Risks and regulatory watch

Regulatory lens: Data protection, cross-border delivery, immigration, AI governance and client-sector regulation affect both.

Practical example

A US$2 billion contract value does not become US$2 billion of annual revenue. Revenue is recognised over delivery periods and may depend on consumption, milestones or renewals. Track conversion from bookings to revenue.

The practical lesson is to reproduce the comparison in a simple worksheet. Put each company in a separate column, use the same period and currency, document adjustments, and keep accounting figures separate from operational indicators.

Action checklist

• Reconcile the latest annual report and subsequent quarterly filing for TCS.
• Reconcile the latest annual report and subsequent quarterly filing for Infosys.
• Align fiscal periods and currencies before calculating growth or margins.
• Separate accounting revenue from transaction value, volume, bookings or user counts.
• Read segment notes, cash-flow statements and commitments—not only the earnings release.
• Stress-test the thesis against regulation, capital intensity and customer concentration.

Evidence checklist

• Annual report, audited financial statements and notes
• Latest quarterly results and investor presentation
• Cash-flow statement and capital-commitment disclosures
• Segment definitions and non-GAAP reconciliation
• Regulatory filings, litigation and risk-factor disclosures
• A dated spreadsheet showing every source and calculation

Common mistakes

• Comparing different fiscal periods without adjustment
• Treating gross transaction value, order value or volume as revenue
• Using management estimates as independent market data
• Ignoring stock compensation, one-offs, tax effects or revaluations
• Comparing consolidated margins across dissimilar business mixes
• Turning a relative business advantage into personalised investment advice

Red flags

• A growth claim with no period or measurement definition
• A margin shown without reconciling adjusted and statutory figures
• User, subscriber or client counts without an activity definition
• Large capital commitments excluded from the cash-flow discussion
• Regulatory or corporate-status changes omitted from the comparison
