IBM Q3 2026 Earnings: Growth Rebounds to 5%, and Most of the Pickup Came From Hardware
IBM's sales growth bounced back to 5% in the third quarter of 2026, three months after its chief executive wrote "this quarter we faltered." By our count, about three quarters of the pickup came from hardware, where mainframe sales fell less steeply than in spring, and a company IBM bought added to software.
The short answer. IBM's sales rose 5% to $17.1 billion from July to September, after 1% in the spring, and IBM kept the yearly forecast it cut in July. Banks, airlines and governments run on IBM machines and software, so its quarter is one gauge of how much those big customers are spending. Our own numbers show that most of the pickup came from hardware, that about half the new software sales match what a bought company sold alone, and that IBM's running AI total is missing from its last three releases.

IBM third quarter 2026 earnings results
IBM's sales grew 5% after a nearly flat spring, but IBM kept the yearly sales forecast it lowered in July. The company says the quarter "exceeded expectations," without saying whose.
IBM reported its results at 4:08 p.m. Eastern time on October 21, 2026. Revenue was $17.1 billion, up 5% from a year earlier. At constant currency, which strips out swings in exchange rates, growth was 6%.
Profit grew faster than sales. Operating earnings per share, IBM's own profit measure that leaves out acquisition costs and some pension items, rose 11% to $2.95. Profit under standard accounting rules rose even faster, helped by a much lower tax bill than a year earlier.
The stock moved in late trading. IBM shares were at $259.35 at 4:59 p.m. Eastern time, 3.1% above the regular close, according to StockTitan price data. Prices after hours come from thin trading and can change sharply before the next regular session.

Why IBM cut its forecast in July
In the spring quarter, IBM's customers moved spending to servers, storage and memory ahead of expected price rises, and several big IBM deals did not close in time. IBM cut its growth forecast for the year.
On July 14, IBM published early second-quarter numbers with a letter from chief executive Arvind Krishna. Revenue for April to June had grown just 1%. He wrote that "in the last few weeks of June, we saw clients shift their quarterly capex spend toward servers, storage, and memory purchases to secure supply-constrained infrastructure ahead of expected price increases." Capex is money spent on equipment.
Then came the admission. "These conditions require our teams to execute perfectly, and this quarter we faltered," the letter said, adding that "numerous large deals failed to close on the timelines we expected." A week later, IBM's second-quarter release cut its 2026 growth forecast to between 4% and 5% at constant currency.
The letter blamed timing as much as demand. In our reading, deals that were only late should show up in later quarters, which makes this quarter the first test of IBM's explanation.
Where did IBM's growth rebound come from?
Mostly from hardware. IBM's hardware unit went from shrinking in the spring to growing this quarter, which by our count is about three quarters of the improvement.
One way to see it is to compare each quarter with the same quarter a year earlier. In the spring, IBM's revenue was $185 million higher than a year before. This quarter it was $772 million higher.
Show the data
| Item | Q2 2026 | Q3 2026 | Change |
|---|---|---|---|
| Infrastructure | -$307M | $148M | +$455M |
| Software | $374M | $595M | +$221M |
| Consulting | $13M | $11M | -$2M |
The swing came mostly from Infrastructure, IBM's hardware unit, which also includes support services. It went from $307 million below the year before to $148 million above it, a change of about $455 million out of the roughly $590 million improvement.
Software did its part, adding about $220 million more than in the spring. Consulting barely moved. So the rebound is mostly IBM's hardware recovering from a weak spring. The software story is real but smaller, and part of it was bought.
Why did IBM mainframe sales fall 20%?
A year ago a new mainframe model had just come out and sales jumped, a high bar to beat. This quarter's 20% fall was about half as steep as the spring's, and IBM's release does not say how much of it is the comparison and how much is deals that failed to close in time.
A mainframe is the large, very reliable computer that banks, airlines and governments use to process huge numbers of transactions. The current model, the z17, was announced in April 2025 for general availability on June 18, 2025.
That launch made 2025 a huge year. IBM Z revenue grew 61% in the third quarter of 2025 and 67% in the fourth. Krishna's July letter called it "the strongest start to a mainframe program in our history."
IBM expected a decline to follow. The same letter said IBM had planned for infrastructure revenue to "decline low-single digits for the year" from the spring onward, and that the spring turned out "worse than our expectations." IBM's second-quarter release put the IBM Z drop at 42%, so this quarter's fall was about half as deep.
IBM still calls the cycle a success. Its earnings presentation says the z17 "continues to outperform the prior generation, delivering >$1 billion incremental revenue." By our rough arithmetic, IBM Z revenue this quarter was still about 29% higher than in the third quarter of 2024, before the z17 arrived.
The software that runs on those machines moved with them. Mainframe software, which IBM calls Transaction Processing, swung to 9% growth after falling 8% in the spring.

| Period | IBM Z mainframes | Power and storage line | All software | Mainframe software |
|---|---|---|---|---|
| Q3 2025 | 61% | 10% | 10% | -1% |
| Q4 2025 | 67% | 3% | 14% | 8% |
| Q1 2026 | 51% | 17% | 11% | 6% |
| Q2 2026 | -42% | 37% | 5% | -8% |
| Q3 2026 | -20% | 31% | 8% | 9% |
The rest of IBM's hardware grew fast. Distributed Infrastructure, which includes IBM's Power servers and storage systems, grew 31% after 37% in the spring. IBM's presentation says storage "delivered record revenue growth and gained market share across the portfolio," but it gives no reason for the growth.
Put together, Infrastructure revenue rose 4% to $3.7 billion, with one line falling hard and another rising fast.
How much of IBM's software growth came from Confluent?
IBM does not say. Confluent's own sales in the same quarter of 2025, before IBM bought it, equal about half of the $595 million IBM's software sales grew.
IBM completed its purchase of Confluent on March 17, 2026. Confluent sells software that moves data between a company's systems as it happens. None of its sales were in IBM's year-earlier quarter, so all of them count as growth this quarter.
Show the data
| Category | Value |
|---|---|
| Software added, Q3 2025 to Q3 2026 | $595.0M |
| Confluent's own sales, Q3 2025 | $298.5M |
As an independent company, Confluent reported $298.5 million of revenue for July to September 2025. IBM's software revenue rose $595 million over the same stretch. Our comparison measures size only. It is not IBM's figure.
If Confluent's sales under IBM matched that level, IBM software grew about 4% without it. If they were higher, the rest grew less. IBM's presentation shows how much acquisitions added to its research spending, but it gives no such figure for sales.
Confluent was inside IBM throughout both quarters, so its inclusion alone does not explain the speed-up since the spring. IBM does not say whether its contribution grew.
Elsewhere in software, Red Hat, which sells the Linux system and tools many companies use to run their own cloud, grew 11%. IBM says yearly recurring sales of its OpenShift tools grew more than 30%. Automation, the tools that run computer operations without people, fell 3%.
Software is still IBM's largest business. It brought in about $46 of every $100 of revenue this quarter, and the profit it keeps from each dollar of sales rose to 35 cents from 33 cents.

What IBM says about Super Intelligence and its AI sales
IBM's chief executive says clients are now "deploying Super Intelligence." IBM does not define the term, and it gives no dollar figure for its AI business, a number it used to quote at the top of its results.
Krishna's quote leads the release: "Our clients are now deploying Super Intelligence in ways that transform entire operating models." Chief financial officer James Kavanaugh used the same words. Neither the release nor the earnings presentation says what IBM means by the phrase or puts a number on it.
The phrase is new in IBM's press releases on StockTitan. Of 806 releases filed under IBM's ticker since June 2020, today's results release is the only one that uses "Super Intelligence" or "superintelligence."
A familiar number is missing. IBM used to report a generative AI "book of business," which its 2025 releases defined as software sales since the start plus new yearly subscription value and consulting contracts signed. It was a running total that grew every quarter, so it never measured one quarter's revenue. The fourth-quarter 2025 release put it at "more than $12.5 billion." IBM has not given the figure in its last three quarterly releases.
The presentation offers a share instead. It says generative AI is "increasingly embedded across Consulting engagements representing 35% of backlog," meaning the consulting work clients have signed but IBM has not yet delivered. Consulting sales were flat in dollars, though, and new consulting contracts fell 2% at constant currency.
Research and development spending rose 15% on IBM's operating measure, and its presentation shows about half of that rise came with companies it bought. So the AI story now comes in words and shares, while the dollar total readers used to track is gone.
What IBM's 2026 forecast means for the fourth quarter
IBM's own forecast allows fourth-quarter growth as low as about 2%, against 12% a year earlier. Its higher cash goal asks its strongest quarter to get stronger.
IBM still expects revenue to grow 4% to 5% at constant currency in 2026, the range it set in July, with currency having no net effect over the year. It now expects free cash flow to rise by "more than $1 billion" from 2025, after saying "about $1 billion" since January. Free cash flow, as IBM measures it, is the cash its operations bring in after equipment spending, leaving out changes in its customer financing book.
By our arithmetic from IBM's own figures, the sales range implies fourth-quarter revenue of about $20.1 billion to $20.7 billion. That is growth of roughly 2% to 5%.
The low end looks weak next to the 12% of late 2025, but currency matters here. IBM's presentation expects exchange rates to cut about 1 to 1.5 points from fourth-quarter growth, so at constant currency the low end is closer to 3%.
The cash goal asks more. IBM needs more than $7.9 billion of free cash flow in the fourth quarter, at least 5% above the $7.6 billion of late 2025. That quarter already produced about half of 2025's free cash flow, so IBM's goal now depends on its strongest season doing better again.
That leaves the July question open. IBM's release does not say whether the large deals that failed to close in the spring quarter have now closed. The fourth quarter is the next test of whether this rebound holds.
| Date | 2026 revenue growth forecast (constant currency) | 2026 free cash flow forecast |
|---|---|---|
| January 28, 2026 | More than 5% | Up about $1B |
| April 22, 2026 | More than 5% | Up about $1B |
| July 22, 2026 | 4% to 5% | Up about $1B |
| October 21, 2026 | 4% to 5% | Up more than $1B |
Source: IBM quarterly results releases of the dates shown. 2025 free cash flow $14.7B; nine-month 2026 free cash flow $7.8B; fourth-quarter 2025 revenue $19.7B, up 12%.
How we counted
Where the rebound came from: for each business we subtracted year-earlier revenue from current revenue, using IBM's second-quarter and third-quarter 2026 releases. Second quarter: Software $7,761M against $7,387M (up $374M), Consulting $5,327M against $5,314M (up $13M), Infrastructure $3,835M against $4,142M (down $307M), total up $185M. Third quarter: Software up $595M, Consulting up $11M, Infrastructure up $148M, total up $772M. Infrastructure's change of $455M is about 77% of the $587M total improvement; the business lines do not add exactly to the totals because of financing, other revenue and rounding.
Fourth-quarter revenue: 2025 revenue of $67,535 million times 1.04 and 1.05 gives $70,236 million to $70,912 million for 2026. We treat reported growth as constant-currency growth for the year because IBM expects currency to be neutral for the year. Subtracting nine-month 2026 revenue of $50,182 million leaves $20,054 million to $20,730 million, against $19,686 million in the fourth quarter of 2025, or reported growth of 1.9% to 5.3%. IBM's presentation expects currency to reduce fourth-quarter growth by about 1 to 1.5 points, so constant-currency growth would be that much higher.
Fourth-quarter free cash flow: 2025 free cash flow of $14,734 million plus $1,000 million is $15,734 million. Subtracting nine-month 2026 free cash flow of $7,787 million leaves more than $7,947 million, against $7,553 million a year earlier.
Software without Confluent: IBM software revenue rose from $7,209 million to $7,804 million, an increase of $595 million. Confluent reported $298.5 million of revenue for the quarter ended September 30, 2025 in its Form 10-Q, which is 50% of that increase. Subtracting it from $7,804 million and comparing with $7,209 million gives growth of about 4.1%. This holds only if Confluent's revenue under IBM equals its year-earlier revenue.
IBM Z: (1 + 0.61) times (1 - 0.20) is 1.288, about 29% above the third quarter of 2024, approximate because both growth rates are rounded. Research spending: IBM's expense summary shows operating R&D up 15%, with acquisitions accounting for 8 points.
Release count: on October 21, 2026 we searched the full text of every press release under the IBM ticker in StockTitan's news database for "Super Intelligence" and "superintelligence". The database holds 806 such releases, dated June 15, 2020 to October 21, 2026.
Frequently asked questions
Did IBM beat expectations in Q3 2026?
IBM says the quarter "exceeded expectations." Revenue grew 5% to $17.1 billion after 1% growth in the second quarter, and operating earnings per share rose 11% to $2.95. This article does not compare the results with analysts' estimates.
How did IBM stock react to Q3 2026 earnings?
IBM shares were at $259.35 at 4:59 p.m. Eastern time on October 21, 2026, in after hours trading following the release. That was 3.1% above the regular close, according to StockTitan price data.
What is IBM's revenue outlook for 2026?
IBM expects 2026 revenue to grow 4% to 5% at constant currency, the range it set in July after cutting it from more than 5%. It expects free cash flow to rise by more than $1 billion from the $14.7 billion of 2025.
Why did IBM mainframe revenue fall?
IBM Z revenue fell 20% against the third quarter of 2025, when it grew 61% after the z17 mainframe launched. In July IBM said it expected infrastructure sales to decline after that launch; the third-quarter release does not say how much of the fall is the comparison and how much is deals that failed to close in time.
Does IBM still report its AI book of business?
Not in its releases. IBM's January 2026 release put its generative AI book of business at more than $12.5 billion, and the three quarterly releases since then do not give the figure.
When is IBM's next dividend?
IBM declared a quarterly dividend of $1.69 a share, payable December 10, 2026 to shareholders of record on November 10. IBM says that with the December 10 payment it will have paid consecutive quarterly dividends every year since 1916. StockTitan's dividend yield calculator shows what a payout means against a share price, and IBM's financial statements are on StockTitan.
