The brokerage has downgraded Tata Consultancy Services and Infosys to Hold while maintaining High Conviction Outperform ratings on Coforge and Persistent Systems. This isn't just about size—it's about business models. Large caps are struggling to transition from traditional services to AI-driven models, while midcaps have built their entire operations around AI from the ground up. The result? Coforge and Persistent are growing at 17-49% annually while TCS and Infosys are stuck in single-digit territory. CLSA's stance reflects a fundamental belief that in an AI-disrupted world, agility and specialized expertise trump scale and legacy relationships.
TCS and Infosys face a structural challenge that no amount of scale can solve: their legacy service mix.
Infosys has acknowledged that AI is cannibalizing its traditional services, forcing it to cut FY27 guidance to just 1.5-3% constant currency growth. Both companies are managing thousands of client relationships through complex AI transitions, creating execution risk and margin pressure. Their sheer scale—TCS serves over 2,500 active clients—once an advantage, now becomes a liability as they must simultaneously modernize massive legacy portfolios while competing with nimble specialists.
Coforge and Persistent Systems represent the opposite end of the spectrum.
This isn't a transition—it's their core business. Persistent Systems has delivered 22 consecutive quarters of revenue growth, with a 25.6% four-year CAGR driven by platform-based digital engineering. Both companies have built proprietary AI platforms (Coforge's 1One AI and Nuuron; Persistent's SASVA platform) that deliver measurable client efficiency gains of 30% or more. This allows them to command premium pricing—Coforge's specialized vertical services command approximately 15% higher billing rates than standard contracts—while expanding margins through automation rather than facing compression.
The performance gap is stark. Coforge reported 49% year-on-year revenue growth in Q1 FY27, with net profit up 110%. Persistent Systems grew 17.4% in FY26 and maintained a 15.6% EBIT margin. In contrast, TCS managed only 2.7% year-on-year revenue growth in Q1 FY27, while Infosys grew just 1% sequentially in constant currency terms. Wipro's IT services revenue actually declined 1.4% quarter-on-quarter. This isn't a temporary blip—it's a structural shift. Midcaps are winning because they're faster, more verticalized, and better positioned for the new AI-led, outcome-centric buying cycle. Enterprises are directing spending toward vendors that can move quickly, bring sharper domain context, and package AI around measurable business outcomes.
Margin trends tell an equally compelling story. Wipro's IT Services EBIT margin fell to 16% in Q1 FY27, a 15-quarter low, with management warning that margin recovery will take several quarters. TCS and Infosys are maintaining margins but facing pressure from wage inflation and AI productivity gains that are compressing traditional service pricing. Meanwhile, Coforge's EBIT margin expanded 414 basis points year-on-year to 16% in Q1 FY27, driven by AI automation of backend processes and cost-saving synergies. Persistent achieved a record quarterly EBIT margin of 16.3% in Q2 FY26. The difference? Midcaps are using AI to expand margins through automation and higher-value services, while large caps are using AI primarily to defend margins in declining legacy businesses.
CLSA's analysis reveals a fundamental difference in deal quality. TCS reported a $9.5 billion order book in Q1 FY27, but sequential revenue growth remained flat at 2.2%, indicating slower conversion. Infosys reduced its FY27 guidance despite a $3.6 billion large deal TCV, signaling execution challenges. In contrast, Coforge's executable order book stands at $2.23 billion, up 44.2% year-on-year, with 95.7% repeat business. Persistent reported $674.5 million in TCV for Q3 FY26, adding five large clients. Midcaps are winning deals because they're faster to close, more specialized in their offerings, and better aligned with the new AI-driven buying patterns. Large deals are taking longer to close and ramp up at established players, while midcaps are converting opportunities more quickly.
Here's where CLSA's analysis gets nuanced. Large caps like TCS and Infosys have excellent client diversification—TCS serves over 2,500 clients across industries and geographies. This provides stability but also complexity. Midcaps have higher concentration—Coforge's top 10 clients contribute 26.1% of revenue, while Persistent's top 10 account for 41.5%. Yet CLSA prefers midcaps because these concentrated relationships are deeper and more strategic. Coforge serves 11 of the top 15 global airlines and 8 of the top 10 travel technology companies, creating barriers to entry that generalist competitors can't match. Persistent has 81% of its revenue from the USA, but this reflects deep relationships with Big Tech and Big Pharma that justify premium valuations. CLSA accepts the concentration risk because the relationships are stickier and more profitable.
Demand trends by vertical reveal why midcaps are outperforming. BFSI, traditionally strong for large caps, is showing mixed signals—TCS and Infosys cite stable technology spending, but Wipro faces continued softness in US BFSI. Midcaps are winning here too: Coforge's BFS business grew 13.8% annually, while Persistent's BFSI business grew 29% year-on-year. Healthcare is another growth area—Coforge's Healthcare & Hi-Tech segment grew 11.6% in Q1 FY27, and Persistent has 26% revenue exposure to healthcare with strong digital engineering demand. Even in travel, a sector facing pressure, Coforge's 18.5% revenue exposure is a strength because of its deep domain expertise serving major global airlines. Large caps are too diversified to benefit from these vertical-specific growth pockets, while midcaps are perfectly positioned.
CLSA cut target prices across the sector, but the reasoning differs by company.
Infosys faced similar treatment with its target cut to Rs 1,653 following guidance reductions. Wipro's target was cut to Rs 218 with a Hold rating due to "relatively weaker growth visibility compared with peers." Yet CLSA maintained High Conviction Outperform on Coforge (target Rs 2,170, 20.4% upside) and Persistent (target Rs 6,246, 12.1% upside). The difference? Midcaps are trading at discounts to their historical averages despite premium current valuations—Coforge's PE of 44.67x is below its 5-year average of 68.5x, while Persistent's 44.64x PE is below its 5-year average of 56.5x.
For large caps to regain favor, CLSA would need to see several things: TCS and Infosys must demonstrate that their AI investments are translating into meaningful revenue contributions beyond the current 6-8% levels. They need to show that they can win large AI transformation deals at scale, not just manage legacy relationships. Margin stability through the AI transition is crucial—any further compression would trigger additional downgrades. For Wipro and Tech Mahindra, the path is even steeper: they need visible margin recovery and evidence that their turnaround strategies are gaining traction. Tech Mahindra's high PE of 29.6x is difficult to justify without clearer evidence of sustained margin improvement and growth acceleration.
For midcaps, the risks are different but real. Coforge and Persistent must maintain their growth momentum while managing client concentration risks. Geographic diversification is a priority—Persistent's 81% USA exposure and Coforge's 62% Americas concentration create vulnerability to US macroeconomic conditions. Execution on large deals and successful integration of acquisitions (Coforge's Encora deal, Persistent's potential Nagarro offer) will be critical. CLSA will be watching whether these companies can scale without losing the agility and specialization that made them successful in the first place.
CLSA's differential rating actions reflect a fundamental belief that the Indian IT sector is undergoing a structural shift, not just a cyclical downturn. The winners will be companies with AI-native business models, specialized vertical expertise, and the agility to adapt to rapidly changing client requirements. The losers will be companies burdened by legacy service models, complex client portfolios, and slow decision-making processes. Scale alone is no longer an advantage—in fact, it's becoming a liability in an AI-disrupted world. CLSA is betting that midcaps like Coforge and Persistent Systems will continue to outperform because they're built for the future, while large caps like TCS and Infosys are still trying to escape the past. For investors, the message is clear: the old rules of IT investing no longer apply. The future belongs to the specialized, the agile, and the AI-native.
