The AI line is paid for out of the rest of the book

Infosys sold $5,145m of services in the quarter to 30 September 2026 and reported that 10.5% of its revenue was AI revenue, against 8.2% in the June quarter. The AI line grew 29% sequentially. Total revenue grew 1.2% in constant currency. Put those rates together on the company's own shares and revenue excluding AI fell about 1.3% over the three months, with the AI line taking 2.3 points of the mix. The AI book is not expanding the services market. It is being funded out of the account beside it, and Infosys is the party reporting both numbers.

For a CIO closing a technology budget by 31 December 2026, the question is no longer whether AI gets its own line. It is which line pays for it, and the supplier has already assumed the answer.

01The AI line grew 29.6% and the rest of the book fell 1.3%

The derivation needs only what Infosys publishes. Take the June quarter's total revenue as 100 and its AI revenue as 8.2. A total that grows 1.2% becomes 101.2, of which 10.5% is 10.626 of AI revenue, so the AI line grew 29.6%, which is the 29% the company stated. The remaining 90.574 compares with 91.8 a quarter earlier. Infosys does not disclose what it counts as AI revenue, so the arithmetic cannot separate new AI work from traditional work relabelled as AI, and the chief executive was asked exactly that on 23 October 2026. What the arithmetic does settle is the total: 1.2% for the whole business, on a line inside it growing at 29%.

The guidance moved the other way. Infosys revised full-year revenue growth to 1%-2% from 1.5%-3% in the same release, kept the operating margin range at 20%-22%, and had grown 1.9% in constant currency across the half year. A services firm that cuts its growth range in the quarter its AI line grew 29% is not describing a market that got bigger. It is describing work moving from one column to another inside a budget that did not move.

02The buyer now asks for the productivity back in price

The pricing conversation moved first, and it moved toward the buyer. On the earnings call of 23 October 2026, Salil Parekh, Infosys's chief executive, said requests for AI productivity benefits to be passed on in price run across the client base, and that some go beyond the return the company is prepared to accept. The rate increase Infosys had assumed for the year did not arrive. Its guidance for the second half names continued sharing of those benefits as a headwind, alongside wage increases and large-deal ramp-ups, which is a supplier telling its shareholders that the client keeps part of the saving.

So on the pricing, what we are seeing is that across the client base, there is demand or request requirement, which is focused on productivity benefits from the AI that are getting passed on.

The segment commentary puts it in the language of individual industries. In communications, Infosys reports clients maintaining tight control over discretionary spend and AI driven productivity expectations putting pressure on pricing and the delivery model. In retail, expectations for AI-led productivity commitments are said to be increasing competitive intensity and reshaping the commercial model. The thing being negotiated is not a discount. It is a productivity commitment written into the contract before the productivity exists, which is why a supplier calls it a reshaping of the commercial model rather than a price cut.

03The margin is being bought with a charge, not with price

Accenture makes the trade legible because it reports the charge separately. Operating margin rose to 15.4% from 14.7%, adjusted margin to 15.8% from 15.6%, revenue grew 5% in local currency and diluted earnings per share reached $13.56, up 12%. Underneath, the company recorded $308m of business optimization costs in fiscal 2026 and $615m in fiscal 2025, primarily for employee severance, and excluded both from the adjusted margin. The charge is excluded. The saving it buys is not, and it lands in the same year.

Cognizant is the only one of the three that prices the mechanism and names AI in the reason. Project Leap was initiated in the second quarter of 2026, and the filing's glossary defines it as a program aimed at streamlining operations and enhancing productivity through AI-led efficiencies. The expected cost is $180m to $250m, of which $150m to $200m is employee severance and other personnel costs. By 30 September 2026 it had recorded $51m in the quarter and $135m since inception, $102m of that employee separation, and it expects $140m to $160m in 2026 with the remainder through the first quarter of 2027. Adjusted operating margin rose 30 basis points while the reported margin fell 60, because the charge is excluded and the saving is not. The filing's own risk factor concedes the trade: the programme could disrupt the business and may not result in anticipated savings.

04The delivery workforce carries it, and it is not shrinking

The saving is not a smaller firm. Accenture ended fiscal 2026 with approximately 814,000 people against 779,000 a year earlier, utilisation up to 93% from 92% and voluntary attrition down to 13% from 14%. Infosys added 4,000 net in the quarter, hired 8,000 graduates, plans approximately 20,000 for the year against attrition it puts near 13%, which it translates as roughly 45,000 people leaving annually, and runs at 85% utilisation, which its management calls optimum. None of these documents describes a workforce being replaced by software. What the severance buys is a workforce reshaped rather than reduced: total headcount rose at both firms that report it, while the charge was taken once and the benefit runs through later quarters.

05The forward book is thinning where the run-rate work sits

Accenture's bookings table is the leading indicator, and it is weaker than the revenue line. Total new bookings rose 3% in local currency against revenue up 5%. By type of work, consulting bookings rose 6% in local currency while consulting revenue rose 3%, and managed services bookings were flat in local currency while managed services revenue rose 6%. Managed services is the multi-year operation, maintenance and infrastructure work that a client buys as a run-rate rather than as a project. In fiscal 2026 the book that funds it stopped growing while the revenue from it grew fastest.

One year is one year. New bookings include renewals, extensions and changes to existing contracts, and Accenture's own filing says they are not comparable to, nor should they be substituted for, an analysis of revenues over time, and that the timing of a small number of large managed services contracts can move the number. The signal is worth testing at the next release, not worth a forecast on its own.

06New scope is being signed, and the annual budget is not growing

The case against this reading is strong and it comes from the same company. Infosys signed $5.2bn of large-deal total contract value in the quarter, 62% of it net new, including one deal over $2bn, and Parekh rejected the substitution reading directly. Asked whether the AI revenue was incremental or traditional work relabelled, he said: “It is not something which is replacing what we have. There is a lot of new work that we are doing.” Both can be true. Total contract value is the whole of a multi-year deal, not a client's annual spend, and a client can sign new AI scope while holding the annual number flat by retiring work it no longer wants. The revenue line is the budget, and it grew 1.2% in the quarter and 1.9% in the half against guidance cut to 1%-2%. What survives is narrower than the claim it started from, and it is still the decision in front of a buyer: on these three issuers, AI work is being funded inside a flat annual budget, and the deal book is not yet converting into a larger one.

07What each seat owes before 31 December 2026

The budget closes in December and the seats do not owe the same thing. The supplier has already assumed the re-cut; the buyer is the only party still deciding.

• CFO: re-cut the technology budget so the AI line is funded from the managed services run-rate rather than a new increment, and show the non-AI line falling in the plan. A 2.3 point mix shift inside a 1.2% total is what the supplier is already reporting. By 31 December 2026.
• CIO: write a productivity pass-through into every renewal that carries an AI commitment, with the baseline unit rate and the client's share of the saving stated in the schedule. Infosys says clients request it across its base and some ask beyond the return it will accept. By 31 December 2026.
• General Counsel: check the notice period on each consulting agreement before the renewal, because Accenture states that many of its consulting contracts are under 12 months and typically permit termination on as little as 30 days' notice, while its managed services contracts generally require longer. The short-dated work is where the pass-through can be enforced. By 31 December 2026.
• Procurement: require the supplier to name, in each statement of work, the baseline headcount or unit rate that an AI saving is measured against. Cognizant is spending $150m to $200m on severance to obtain the saving, and the buyer's share of it is only what the contract says. By 31 December 2026.

08What a board should put to its management

The question is not whether the company is buying AI. It is whether the same outcome is being bought twice, once through the run-rate and once through the programme, and the budget is the last document that can answer it before the money is committed.

• Which outcomes in the plan are claimed by both the managed services run-rate and the AI programme, and what is the total paid for each?
• What productivity commitment have we signed in the AI contracts, and against what baseline is it measured?
• If the supplier's AI revenue grows 29% again in the quarter to 31 December 2026 while our total spend is flat, which of our lines absorbs it?
• Which of our supplier contracts can we terminate at short notice without penalty, and who holds that list?
• What evidence do we hold that the AI output is used, rather than paid for?

09The dates that test this reading

• December 2026: Accenture reports the quarter ending 30 November 2026. Managed services bookings growing in local currency would make the thinning forward book a single year rather than a trend.
• The quarter to 31 December 2026: Infosys reports its AI share. Repeat the two rates of the September quarter and the share reaches 13.4% of revenue; a share below 12% would mean the AI line grew less than 16% sequentially.
• By the first quarter of 2027: Cognizant's Project Leap charge should land inside $180m to $250m. A total above the range means the productivity cost more than it disclosed.
• The quarter to 31 March 2027: if Infosys reports sequential growth in revenue excluding AI while the AI share keeps rising, this reading fails. AI would be incremental and the budget expanding.

The number to hold a supplier to is not its AI growth rate. It is the share of the client's annual spend the AI line represents, and whether the client chose to move it or had it moved for them. Infosys has published the arithmetic for one quarter. Every buyer carrying a flat run-rate and a rising AI line is looking at the same subtraction, and a budget signed in December is where it stops being a trend and becomes a decision.
