TCS: Is This a Good Business? A Financial Analyst's View
Tata Consultancy Services is an Indian IT services firm that earns revenue from technology and consulting labour services. Clients (banks, retailers, manufacturers and other large companies around the world) pay TCS for the construction, maintenance and modernization of their software systems, move them to the cloud, and have them run back-office IT operations for them under long-term contracts. Revenue is "billed hours plus fixed-fee project value" scaled up to hundreds of thousands of employees, thousands of client relationships. The service is a part of the client's daily business (payroll systems, banking cores, supply chain), making it fairly predictable in terms of revenue from one year to the next, a quality that makes it sticky and recurring, meaning easy to bind and repeat.
The model depicts a company that is large, profitable and steadily growing. FY2025 revenue was ₹255,324 Cr with net profit of ₹48,797 Cr, a margin of about 19.1%. FY2026 revenue rose to ₹267,021 Cr (+4.6% YoY) with profit of ₹49,454 Cr, though margin compressed slightly to 18.5%. Assuming a revenue growth of 6% per year and projecting that margin will remain at 18.5% for FY2027 and FY2028, the forecast holds that FY2027 revenue is ₹283,042 Cr with a net profit of ₹52,421 Cr and FY2028 revenue is ₹300,025 Cr with a net profit of ₹55,567 Cr. To summarise: the net margins, in the high teens range, have been maintained across the period, and the model assumes performance improves modestly on the 4.6% actual pace set in FY2026.
Given these figures, TCS appears to be a solid business – it turns nearly 1 of every 5 rupee of its revenue into net profit, a ratio most businesses can only dream of, and does so in large volumes with growth that is modest but positive as opposed to volatile. While it isn't a hyper-growth story, that's the kind of thing a founder wants to see, in terms of margin, base, and cyclicality. The greatest threat to this prediction is the growth assumption itself – the 6% figure is not justified through operations, and given client budget cuts, AI-driven pricing pressure on traditional staffing-based contracts, and global recession risk, real growth could just as easily fall below the 4.6% actually delivered in FY2026 as reach the modeled 6%.
Reflection: The assumption that I am the least confident with is holding the net profit margin at 18.5% for the next two years; in reality, wage inflation, rupee-dollar currency fluctuation, and pricing pressure caused by artificial intelligence could move this margin meaningfully either way, and the model has not captured any of these factors.
