IBM delivered a knockout quarter. The company reported earnings of $4.52 per share on January 28, 2026, sailing past the $4.32 consensus estimate.
Revenue for the fourth quarter totaled $19.69 billion. Wall Street had expected $19.23 billion. The beat wasn’t small either—IBM exceeded projections by nearly half a billion dollars.
The stock reacted immediately. Shares jumped 8% in trading as investors digested the results.
Net income told an even better story. IBM earned $5.6 billion for the quarter, or $5.88 per share. That’s almost double the $2.92 billion, or $3.09 per share, from the same quarter last year.
Full-year numbers showed consistent strength across the board. Revenue reached $67.5 billion, up 6% from 2024. But the real eye-opener was free cash flow.
IBM generated $14.7 billion in cash during 2025. That’s up 16% and marks the highest level the company has seen in over a decade. This kind of cash generation gives IBM flexibility to invest, return money to shareholders, or make strategic moves.
CEO Arvind Krishna credited the company’s artificial intelligence business for much of the momentum. The generative AI book now totals more than $12.5 billion across all segments.

Mainframes Make Unexpected Comeback
Infrastructure turned in the quarter’s biggest surprise. The segment pulled in $5.1 billion, representing 21% growth from a year ago.
Mainframes drove the gains. IBM Z Systems, the company’s flagship mainframe line, grew 67% year-over-year in Q4. That’s not a typo—mainframes, often written off as legacy technology, just posted double-digit growth.
The z17 systems attracted customers with AI-led innovation built directly into the hardware. This isn’t your grandfather’s mainframe anymore. IBM engineered these machines to handle modern workloads including AI processing.
Distributed infrastructure remained stable. New Power system adoption offset some weakness in storage products experiencing normal product-cycle dynamics. Overall, the infrastructure segment expanded profit margins by 450 basis points for the full year.
Software continued its winning streak. The division brought in $9 billion during Q4, up 14% from last year. Growth accelerated to 11% for the quarter with over 7 percentage points coming from organic expansion rather than acquisitions.
Annual recurring revenue in the software business climbed to $23.6 billion. That represents more than $2 billion in growth from where things stood at the end of 2024. This recurring revenue provides predictable income streams that Wall Street loves.
Consulting Finally Finds Its Footing
After a rough first half, consulting got back on track. The segment posted $5.3 billion in Q4 revenue, up 1% year-over-year. Full-year consulting revenue came to $21.1 billion, growing 0.4%.
The consulting team closed its biggest GenAI bookings quarter on record. New business exceeded $2 billion for the three-month period. Total GenAI bookings in consulting have now surpassed $10.5 billion since IBM started tracking this metric.
The $32 billion consulting backlog grew 2% at actual rates. This pipeline gives IBM visibility into 2026 and beyond. Companies don’t cancel these contracts lightly, especially when they’re tied to digital transformation initiatives.
CFO James Kavanaugh highlighted margin expansion during the earnings presentation. Adjusted EBITDA margin grew by roughly 230 basis points, translating to 17% growth for the fiscal year.
The company also achieved $4.5 billion in productivity savings at the 2025 exit run rate. IBM managed to cut costs while simultaneously investing in growth areas like AI and hybrid cloud.
Data offerings within software grew 19% year-over-year. Automation solutions jumped 14%. Red Hat products contributed solid gains as hybrid cloud adoption continued.
The hybrid cloud category in software grew 8% compared to last year. This aligns with IBM’s strategy of positioning itself as a software-led hybrid cloud and AI platform company rather than a hardware vendor.
IBM laid out its 2026 roadmap during the call. The company expects revenue growth to exceed 5% at constant currency. That’s a deceleration from 8% growth in 2025, but analysts had only penciled in 4.6% growth.
Software is expected to lead the charge. IBM projects the software segment will accelerate to 10% growth in 2026, driven by organic initiatives rather than acquisitions.
Operating pre-tax income margin should expand by about a point. Free cash flow is projected to increase by approximately $1 billion year-over-year, representing high single-digit growth from the record 2025 level.
Krishna dropped another piece of news during the analyst call. IBM is on pace to deliver its first large-scale quantum computer by 2029. This puts the company at the forefront of yet another emerging technology alongside AI.
The board declared a dividend of $1.68 per share. The payment date is March 10. When IBM pays this dividend, it will mark 110 consecutive years of quarterly dividends—a streak that spans two world wars, the Great Depression, and every economic crisis since.
