IBM Q3 2026 revenue rises 5% to $17.1B on software

IBM reported third-quarter 2026 revenue of $17.1 billion on October 21, up 5% from a year earlier, or 6% in constant currency. Software grew 8% to $7.8 billion, led by Red Hat and data products. Sales of IBM Z mainframes fell 20%.

IBM now expects 2026 free cash flow to rise by more than $1 billion over last year.

The quarter in numbers

The results beat estimates of $16.82 billion in revenue and $2.86 in adjusted earnings per share, Cryptopolitan reports. Constant currency strips out exchange-rate swings, so it shows the underlying growth.

Measure	Q3 2026	Versus Q3 2025
Revenue	$17.1B	up 5%
GAAP earnings per share (continuing operations)	$2.31	$1.84 a year earlier
Operating earnings per share	$2.95	$2.65 a year earlier
GAAP gross margin	56.8%	57.3% a year earlier
Free cash flow	$3.0B	up $0.7B

Part of the profit jump came from taxes. IBM's effective tax rate fell to 11.9% from 28.2% a year earlier, TradingKey notes, so earnings per share grew faster than pre-tax profit.

"Disciplined execution throughout the quarter drove accelerated revenue growth and strong free cash flow," chief executive Arvind Krishna said. Shares slipped after the close, Cryptopolitan reports.

Segment by segment

IBM reports four segments. Software, its largest, includes Red Hat, the open-source Linux and cloud software company IBM owns.

Segment	Revenue	Change
Software	$7.8B	up 8%
Consulting	$5.3B	flat (up 2% in constant currency)
Infrastructure	$3.7B	up 4%
Financing	$0.2B	down 4%

Inside software, Hybrid Cloud, which includes Red Hat, grew 11%. Data software grew fastest, at 19%, and transaction processing rose 9%. Automation software fell 3%.

Infrastructure moved in two directions. Distributed infrastructure, IBM's non-mainframe servers and storage, jumped 31%. IBM Z, its mainframe computer line, fell 20%.

Consulting was flat. Chief financial officer James Kavanaugh said AI-related work now makes up about 30% of consulting revenue and 35% of its backlog, Cryptopolitan reports.

Guidance and cash

IBM kept its 2026 forecast of 4% to 5% revenue growth in constant currency. It expects currency to be neutral at current rates.

The cash outlook rose. IBM generated $3.0 billion of free cash flow in the quarter, up $0.7 billion, and $4.0 billion from operations. It now expects full-year free cash flow to grow by more than $1 billion. It spent $11.4 billion on acquisitions in the first nine months of 2026.

IBM ended the quarter with $11.1 billion in cash and marketable securities and $63.8 billion of total debt. It declared a quarterly dividend of $1.69 a share, payable December 10.

What this means for developers

IBM's growth is coming from software it owns, while its oldest hardware line shrinks.

• Red Hat is still a growth engine. Hybrid Cloud, which includes Red Hat, grew 11%. Teams that depend on Red Hat products can expect them to stay central to IBM's plans.
• Data software is the fastest-growing piece. At 19% growth, IBM's data products are where it is winning the most new spending. Expect IBM sales teams to lead with them.
• AI is now a third of IBM consulting. If you hire IBM for IT services, AI work will show up in most proposals. Ask for the delivery plan and the measures of success in writing.
• Watch the acquisitions. IBM spent $11.4 billion buying companies in nine months. A tool your team relies on could become an IBM product, with new pricing and terms.
