🗞️ Key Recent Developments (Past 18 Months)
India's IT exports crossed $224.4 billion in FY25, a 12.48% year-on-year increase from $199.5 billion in FY24. Total IT-BPM sector revenue (including domestic) is estimated at $283 billion for FY25 — a historic high. The US remained the dominant market at 54.1% of exports, with Europe contributing 30.8%.
AI deals now constitute ~74% of all new contract wins among major Indian IT firms over the last six quarters. HCLTech led with 139 AI-focused deals (72% of its total), TCS followed with 81 AI deals (76% of total), and Wipro showed the highest relative emphasis, with 83 AI-themed deals out of 99 total. This marks a decisive pivot from traditional digital transformation to AI-centric engagements.
Infosys CEO Salil Parekh confirmed the company is now working with 90% of its top 200 clients on AI-led programmes, running 4,600 active AI projects. TCS COO Aarthi Subramanian noted that 2025 marked a shift "from POCs and pilots to ROI-led scaled implementations."
Infosys–Anthropic Partnership: Infosys unveiled its "AI-First Value Framework" and disclosed a partnership with U.S.-based Anthropic to develop and deploy advanced enterprise AI agents across multiple sectors. The deal targets a projected $300–400 billion AI services opportunity by 2030.
Tech M&A at 3-year high: The top five IT firms executed 7 acquisitions in 2025 (vs 5 in 2024 and 2 in 2023), with total disclosed deal value crossing $750 million. Key deals: Wipro's $375M acquisition of Harman DTS; Infosys acquiring 75% of Versent Group (Telstra) for ~$158M; HCLTech acquiring Hewlett Packard Enterprise's Telco Solutions business for $160M.
Largest ER&D acquisition ever by an Indian IT firm: Coforge's $2.35 billion takeover of US-based Encora (mid-cap category), signaling aggressive consolidation in the engineering R&D segment. India's tech M&A activity in 2025 hit total deal values of $26–29 billion, a three-year high.
IT spending in India reached $145.4 billion in 2024, projected to rise 11.1% to $161.5 billion in 2025. India's public cloud market is projected to reach $17.8 billion by 2027 (CAGR: 23.4%). India's AI market is projected to reach $28.8 billion by 2025 at a 45% CAGR.
India holds ~65% of global IT offshoring and processes roughly 40% of global business outsourcing. The country has over 1,000 global delivery centers across 80 countries. Non-metro IT hiring hubs like Udaipur, Coimbatore, and Nagpur recorded 50%+ hiring growth in H1 2025, significantly outpacing Bengaluru and NCR (12–15%).
Key Investor Metrics & Sector Analysis
These are the indicators that professional analysts track to assess the health and trajectory of Indian IT companies. Every long-term investor in the sector should monitor these.
🔑 The 8 Metrics Every IT Investor Should Track
1. Deal Wins & Total Contract Value (TCV)
The single most forward-looking indicator. Large deal TCV signals pipeline revenue for the next 2–5 years. Watch quarterly TCV announcements. TCS typically targets $7–9B per quarter. A drop in TCV is an early warning sign before revenue softness appears.
2. Revenue Growth (CC vs USD)
Always compare constant currency (CC) growth, which strips out forex effects. A company can report flat USD revenue while actually growing 4–6% in real terms due to INR depreciation. Track both for the full picture.
3. EBIT / Operating Margin
Healthy Indian IT EBIT margins range from 20–26%. TCS is the benchmark at ~24–25%. Margin pressure can come from wage hikes (typically April), higher subcontractor costs, or underutilization. Watch for margin trajectory, not just a single quarter.
4. Attrition Rate
High attrition (above 20%+) was a major headwind in FY22–FY23. It has since normalized to 12–15% for large firms. Lower attrition reduces hiring and training costs, stabilizes project continuity, and improves margins. Rising attrition is a warning signal.
5. Digital Revenue Mix
Tracks the proportion of revenues from cloud, AI, cybersecurity, data analytics vs legacy application maintenance. Higher digital mix signals premium pricing power and higher growth potential. Infosys and HCLTech are leaders in digital revenue reporting.
6. Top Client Concentration
If the top 5 clients contribute more than 25–30% of revenue, the business faces concentration risk. Examine the percentage from the top 10 and top 20 clients. Healthier companies have a broader, more diversified client base. Compare annually for trends.
7. Headcount & Utilization
Net headcount change tells you whether companies are confident about future demand. Rising utilization rates (above 83–85%) indicate healthy demand momentum. The Big 5 collectively cut ~58,000 jobs over FY24–25, signaling cautious demand and AI-driven productivity.
8. Free Cash Flow & Dividend
Indian IT is a capital-light business. High free cash flow conversion (target: 90–100% of net income) is a mark of quality. TCS and Infosys consistently return cash to shareholders via dividends and buybacks, making them "annuity-style" holdings for long-term investors.
🌐 Structural Strengths: Why Indian IT Has Long-Term Staying Power
Despite near-term headwinds, several structural factors give the Indian IT sector durable advantages that are difficult for competitors to replicate:
India's IT cities offer 30–50% cost savings per FTE compared to alternatives like Singapore, Manila, or Kuala Lumpur. While AI is closing some gaps, complex project execution remains significantly cheaper from India, sustaining the core outsourcing model.
India produces approximately 1.5 million engineering graduates annually. The sector employs 5.4 million workers, with 2 million classified as digitally skilled. Global Capability Centres (GCCs) are expected to employ 4–5 million people by 2030, expanding India's IT footprint well beyond traditional IT services firms.
Indian IT firms are not passive recipients of AI disruption — they are active AI integrators. With AI now embedded in 74% of new contracts, firms like TCS (620 AI engagements), Infosys (4,600 AI projects), and HCLTech ($2.4B in AI contracts) are positioning themselves as irreplaceable partners in enterprise AI transformation.
As revenues are earned in USD/EUR and costs are largely in INR, a weakening rupee directly expands profit margins when translated back. A 5% INR depreciation can boost reported margins by 80–100 basis points — a structural advantage vs. purely domestic competitors.
Indian IT firms serve clients across BFSI, healthcare, manufacturing, retail, and telecom — making them more resilient to single-sector recessions. While tech spending cuts in the US do hurt (as seen in FY24), the sector has historically recovered within 2–4 quarters.

"We are seeing large AI-led service transformations, net new deals happening, and service transformation increasingly becoming core to decision-making in every pursuit."— C Vijayakumar, CEO, HCLTech
Long-Term Opportunities: The HCLSoftware segment creates a recurring revenue "moat" unlike pure-services IT firms. ER&D growth in aerospace, automotive, and semiconductor sectors. AI-driven legacy modernization in BFSI. The company's balance of services + software products + ER&D makes it the most structurally diversified of the Big 5 — and potentially best positioned for an outcome-based pricing world.
*Revenue declined for two consecutive years as Wipro underwent significant restructuring. Recovery is expected in FY26.
Industries Served: Banking, Financial Services & Insurance (BFSI, ~33%), Consumer (~14%), Technology (~14%), Healthcare (~10%), Communications (~9%), Energy, Natural Resources & Utilities (~9%), Manufacturing (~6%), Others (~5%).
Key Global Clients (Examples): Société Générale, ABB, Metro AG, FrieslandCampina, Marqeta, UK Government agencies, major US telecom providers. Wipro serves clients across more than 65 countries.
Core Services: Application services, cloud (Wipro FullStride Cloud), AI-driven business process transformation (Wipro ai360), cybersecurity (CyberDefense), product and ER&D services, SAP transformation, and integrated infrastructure services.
AI & Strategic Highlights: Wipro showed the highest relative emphasis on AI among the Big 5, with 83 of 99 deal wins (84%) carrying an AI theme over six quarters. In Q1 FY26, Wipro secured 16 large deals including two mega-deals, with $5 billion in total bookings and the highest quarterly profit growth of the Big 5 (+6.4%). Its $375M acquisition of Harman DTS (a HARMAN International / Samsung subsidiary) in December 2025 significantly strengthened its embedded product engineering and IoT capabilities. CEO Srini Pallia confirmed that AI has become central to clients' cost optimization strategies, driving vendor consolidation.
"Clients are now focused on cost optimisation, vendor consolidation and a clear shift towards AI-led transformation."— Srini Pallia, CEO, Wipro
Long-Term Opportunities: Wipro's restructuring and strategic reorientation (effective April 2025) positions it for leaner, higher-margin growth in FY26 and FY27. The Harman DTS acquisition is a transformative bet on embedded AI in physical products (automotive, telecom equipment, consumer electronics). Analyst consensus suggests Wipro's trough in revenue growth may have been FY25, with FY26 recovery gradual but real.
*Under "Project Fortius" turnaround. Margin recovery expected in FY26/27. Revenue growth also declined; recovery underway.
Industries Served: Communications, Media & Entertainment (~40% — unique industry dominance), Technology (~20%), BFSI (~12%), Manufacturing (~10%), Healthcare (~7%), Retail & Others (~11%).
Key Global Clients (Examples): AT&T, Verizon, BT Group, SoftBank, Deutsche Telekom, ABN AMRO, Raytheon, major European telecom operators. Tech Mahindra has a distinctive presence as a telecom-specialist IT firm.
Core Services: Network services and 5G transformation (a core differentiator), application services, cloud, AI/ML (sector-specific AI models), BPO, cybersecurity, and digital engineering. Tech Mahindra is the only Indian IT firm with deep 5G network engineering expertise — a structural advantage as global telecom networks evolve.
AI & Strategic Highlights: Tech Mahindra is undergoing "Project Fortius" — a multi-year transformation to higher-margin, AI-led services. CEO Mohit Joshi (appointed 2023) is repositioning the company's go-to-market toward outcome-based pricing. In late 2025, Tech Mahindra announced one of the largest deals in its history — a multi-year engagement with a European telecom services provider for AI-led operational transformation. The company partnered with NVIDIA for 5G and AI initiatives, and with SoftBank for "large telco models" — large language models specifically designed for telecom use cases. Its AI deal wins are now at a 5-year high on a last-twelve-months basis.
"Our deal wins on an LTM basis are the highest we have achieved in the past five years, reflecting an improved deal-win run-rate over the past several quarters."— Mohit Joshi, CEO, Tech Mahindra
Long-Term Opportunities: 5G monetization by global telecom operators is a multi-decade opportunity that no other large-cap Indian IT firm can serve with the same depth. As global telecoms shift from 5G deployment to 5G monetization (AI-native networks, network slicing, private 5G for enterprises), Tech Mahindra is uniquely positioned. Additionally, its AI model specialization for telecom creates IP-based revenue potential that is fundamentally different from headcount-driven outsourcing.
Risks, Opportunities & The Long-Term Outlook
A balanced, non-promotional assessment of what could go right and what could go wrong for Indian IT investors over the next 3–5 years. This is not investment advice — consult your financial advisor.
⚠️ Key Risks to Watch
- US Macroeconomic Slowdown: ~54% of revenues come from US clients. A recession or further tech spending freeze directly impacts deal volumes and revenue growth with a 1–2 quarter lag.
- AI Displacement of IT Jobs (Deflationary Pressure): As AI tools automate coding, testing, and basic application management, the revenue-per-employee model faces headwinds. Indian IT firms must shift to outcome-based pricing or face deflation in their core markets.
- US Immigration/Visa Policy: Restrictions on H-1B visas could limit the ability of Indian IT firms to deploy engineers onsite at US client locations — a core delivery model, especially for new project ramp-ups.
- GCC Competition: Global Capability Centres — in-house tech operations set up directly by multinationals in India — are increasingly competing for talent and for work that would otherwise go to IT services firms.
- Client Concentration in BFSI: With 30–35% of revenues tied to financial sector clients, any prolonged downturn in global banking or insurance IT budgets creates significant top-line risk.
- Valuation Premium: The Nifty IT index trades at a ~20% premium to the Nifty 50, despite a lower earnings CAGR forecast (6–8% vs 14–15%). Elevated valuations leave less room for disappointment.
✅ Key Opportunities to Watch
- AI Services as the Next S-Curve: AI deals constituting 74% of new contract wins signals the beginning of a multi-decade AI services cycle. The global AI services market could reach $300–400 billion by 2030 — Indian IT firms are best positioned to capture a disproportionate share.
- Large Deal Pipeline Recovery: After three years of muted growth, analyst forecasts suggest FY27 revenue growth recovery to ~8% as AI deal ramp-ups convert to revenue. The pipeline is already visible in TCV data.
- Cloud Expansion: India's domestic public cloud market is projected to hit $17.8B by 2027 (CAGR: 23.4%). Globally, enterprises are in the early stages of cloud migration — a process that will take 10+ years to complete and directly feeds Indian IT revenues.
- Blockchain in Banking: Infosys Finacle serves 1,300+ global banks. As banks globally adopt blockchain for trade finance, cross-border payments, and tokenization, Indian IT firms are ideally placed to deliver implementation and integration services.
- Engineering R&D (ER&D) Expansion: ER&D is growing at 7.8% annually, faster than core IT services. India's engineering talent base makes it a global hub for semiconductor, automotive, aerospace, and medical device R&D outsourcing.
- Favorable Demographics & Cost Structure: India's large, affordable engineering workforce continues to attract global corporations looking to cut costs while maintaining quality — a structural advantage that will persist for at least another decade.
📈 Long-Term Outlook: The AI Era for Indian IT
The near-term picture for Indian IT (FY26) remains one of cautious recovery, with revenue growth estimates ranging from 3–5% for the large caps. However, the structural case for the sector over a 5–10 year horizon remains compelling for several reasons:
First, the volume of AI-related deal wins is unprecedented in the sector's history. The pivot from "IT services" to "AI transformation partner" is not cosmetic — it represents a fundamental upward repricing of what Indian IT can charge per engagement.
Second, the global enterprise AI opportunity is enormous and under-penetrated. Infosys is targeting a $300–400 billion incremental AI services market by 2030. Even capturing 15–20% of this market would represent a step-change in revenues for the sector.
Third, headcount deflation (job cuts, hiring freezes) over FY24–25 has already reset the cost base. When revenue growth accelerates in FY27, the operational leverage will be significant — translating higher revenue growth directly to margin expansion and earnings acceleration.
Fourth, the Indian rupee's long-term trajectory remains one of gradual depreciation against the USD — a sustained tailwind for companies earning in USD and paying costs in INR.
The bear case is real: AI could structurally deflate IT services pricing, compressing revenue even as deal volumes rise. The transition to outcome-based pricing will be painful for firms with legacy headcount-heavy models. But those who execute the transition successfully stand to emerge as the dominant AI integration firms of the next decade.
