Management did not repeat the 25% margin goal analysts cite, as TCS growth held at 0.5%, below Q4 FY26's 1.2%

Growth is positive, but no faster than Q1 and below Q4 FY26

In April the chief executive of Tata Consultancy Services described a regular first quarter and second quarter and said the company was also expecting a stronger first half; he named no number and no baseline for stronger. In the September 2026 quarter revenue grew 0.5% from the quarter before in constant currency, meaning with exchange-rate moves taken out. That is a slowdown from the 1.2% of Q4 FY26. By the CEO's account the quarter matched the one before it, so the half ran at that pace twice over, by our arithmetic, roughly half the pace of the two quarters before it. An analyst said a better second quarter had been hoped for at the July call, which we do not hold.

The margin is holding, and the year-end goal has gone quiet

In April the finance chief said the annual pay rise would cost 150 to 200 basis points of margin, as in past cycles. Last quarter the company gave its operating margin as 24%, without a decimal, against 25.3% before the pay rise. By our arithmetic that is a fall of about 1.3 points if 24% is exact, at or below the low end of the hit flagged.

What held it there matters more than the figure. The finance chief named currency gains and operating leverage, and told an analyst of a lower outlay this time, given its performance against internal targets. Pushing the other way were a larger bench of staff hired ahead of projects, more subcontractors, and spending on partnerships and acquisitions. And the company expects a drag in the second half from a proposed acquisition, whose timing depends on approvals.

Four asked about 25%; the CFO gave no figure or date

Four analysts on the call asked about a year-end operating margin of 25%. At least two described it as the company's own commitment or guidance. We did not find the figure in our summaries of the January and April calls, which record the finance chief speaking of climbing toward 26% (January) and moving toward 26% on a longer-term basis (April).

On this call the finance chief neither repeated nor disowned it, and gave it no date or figure on the call. One reply to an analyst is garbled in the transcript (it reads 'we want to end up' and then turns to investment), so we do not build on it. He said the long-term aspiration stands and that near-term priority is investment. His one summary was this: "While it is an uphill task, we'll continue to endeavor to inch up on our margins." A long-term aspiration costs nothing to repeat. A year-end number can be checked at the year-end results, two reports away, with the acquisition drag still to come.

AI is growing; by our arithmetic the rest is shrinking

The line management showcased most is AI. Its annualised revenue went from above $2.3 billion in April to above $3.1 billion now, over a tenth of revenue. An analyst put the quarter's AI growth at 19% and no one on the call disputed it; its basis was not stated on the call. By our arithmetic AI added more quarterly revenue than the whole company did, which implies, on these inputs, that the rest of the business shrank by about 1.2%. That rests on an analyst's number and on revenue we approximate, and the call carried no definition of AI revenue. The COO, answering another analyst, said the company is also gaining share in traditional services, helped by vendor consolidation, so the split is not one management draws. In April, asked about margins on AI and data services, management declined to give one; this time the finance chief said AI revenue is "coming in at a much higher margin than our company average." No number came with it.

What would have to be true, and what we do not know

The finance chief's route to a higher margin runs through growth putting the larger bench to work and lower subcontractor cost. Among the levers the finance chief named were utilisation, productivity, subcontractor cost and the rate average. Against that stand the second-half drag and the usual year-end furlough season.

An analyst put the fall in India revenue at about 10%, which the chief executive attributed to a project deferral; he gave no date on the call for its return and said the revenue should come. We do not hold the July call, so we cannot say whether the 25% was set there. On this call the company repeated the long-term aspiration and stayed vague on the number analysts say comes due soon.
