Infosys makes money by being the operating system that large enterprises don't want to build themselves. Strip away the branding and platform names, and the core transaction is straightforward: a Fortune 500 company needs technology work done — building software, migrating to the cloud, maintaining legacy systems, running business processes — and Infosys provides the people, processes, and platforms to do it. The trick is in how the work gets divided. About 25-30% of Infosys' workforce sits on-site with clients in New York, London, Frankfurt, or Sydney. They gather requirements, manage relationships, attend steering committees, and handle the work that requires physical proximity or cultural fluency. The remaining 70-75% sits in India — Bengaluru, Mysuru, Pune, Hyderabad, Chennai — writing code, running tests, managing infrastructure, and processing transactions at roughly one-third to one-fifth the cost of equivalent Western labor. This split is the Global Delivery Model, and it's been Infosys' economic engine since the 1990s. It produces operating margins around 20-21%, which is remarkable for a services business with 328,000 employees. The revenue breaks down into four streams, though they blur at the edges. IT services is the heavyweight — application development, systems integration, infrastructure management, testing, and enterprise package implementation (SAP, Oracle, Salesforce, ServiceNow). This is where most of the $20.2 billion comes from. Consulting, delivered through Infosys Consulting, is the upstream play — advising on strategy, architecture, and transformation roadmaps before the implementation work begins. It's lower revenue but higher margin, and more importantly, it lets Infosys shape the technology decisions that generate downstream implementation contracts. Business process management (BPM) handles the repetitive operational work — finance and accounting, procurement, HR administration, customer service — on multi-year contracts that provide steady recurring revenue. And then there are products and platforms: Finacle for core banking (embedded in 100+ banks globally), AssistEdge for automation, Cobalt for cloud services, and Topaz for AI. These carry software-like margins and create switching costs that pure services work doesn't. Geographically, North America accounts for roughly 58% of FY2026 revenue, Europe about 30%, and the rest of the world fills in the remainder. Financial services is the largest vertical, followed by retail, manufacturing, and energy. No single client exceeds 3-4% of revenue, but the top accounts run deep — multi-year relationships worth hundreds of millions each, with Infosys teams embedded so thoroughly in client operations that switching vendors would mean months of transition risk in systems running payroll, lending, or patient care. In FY2026, the company signed $14.9 billion in large deals (contracts over $50 million in total value), up 24% year-over-year. That number matters because large deals provide revenue visibility for years ahead and deepen the operational integration that makes clients sticky. The Mysuru training campus — 337 acres, capacity for 15,000 simultaneous trainees — is the factory floor for this model. When a new technology wave hits (cloud five years ago, generative AI now), Infosys can retrain thousands of engineers in months rather than hiring externally at premium rates. It's an underappreciated asset. The campus ensures consistent quality regardless of which office or project an engineer comes from, and it gives clients confidence that the person assigned to their account has been through a standardized program. The 20,000 freshers hired annually aren't just headcount — they're raw material entering a production system designed to turn engineering graduates into billable consultants within six months.
