Not among the names typically associated with the AI boom, IBM said its results were boosted by software sales, with handsome growth for its AI-focused offerings.

Revenue rose 12% to $19.7 billion, and adjusted earnings increased 15% to $4.52 per share – both beating Wall Street’s estimates of $19.23 billion revenue and $4.32 EPS.

Revenue from IBM’s software unit, which includes cloud, Red Hat offerings, AI software such as WatsonX, and automation and data products, rose 14% to $9 billion.

“Our generative AI book of business now stands at more than $12.5 billion. This capped a strong 2025 for IBM where we exceeded expectations for revenue, profit and free cash flow,” CEO Arvind Krishna said in a statement. AI customers are shifting from experimenting to scaling, he said on the analyst call. 

The company’s AI business book was $9.5 billion as of the end of the third quarter. IBM expects 2026 revenue to increase by more than 5%, slightly higher than analysts’ 4.6% growth estimate.

If the after-hours gains hold up on Thursday, it would be the stock’s best performance since last October, when it gained nearly 8% following IBM’s third quarter report.

Since then, the stock has traded within a narrow range. As of the last close, IBM was down 0.7% so far this year.
