IBM results beat expectations as the company pushes up full-year guidance

• IBM delivered stronger results than expected and raised its forecast for full-year free cash flow.
• The software, hardware and consulting company saw strength in sales of infrastructure, such as mainframe computers.
• IBM shares have outperformed the S&P 500 by a significant margin this year.

IBM shares fell as much as 5% in extended trading on Wednesday after the tech conglomerate issued second-quarter results that topped Wall Street projections.

Here's how the company did in comparison with LSEG consensus:

• Earnings per share:$2.80 adjusted vs. $2.64 expected
• Revenue:$16.98 billion vs. $16.59 billion

IBM's revenue increased nearly 8% year over year in the quarter, according to a statement. Growth in the first quarter was below 1%. Net income, which includes costs related to acquisitions, rose to $2.19 billion, or $2.31 per share, from $1.83 billion, or $1.96 per share, a year ago.

Software revenue climbed about 10% to $7.39 billion, exceeding the $7.43 billion consensus among analysts surveyed by StreetAccount. The unit's gross margin of 83.9%, barely narrower than StreetAccount's 84.0% consensus.

Revenue from consulting rose almost 3% to $5.31 billion, higher than StreetAccount's $5.16 billion consensus. Infrastructure revenue went up 14% to $4.14 billion, above the $3.75 billion StreetAccount average estimate.

During the quarter, IBM announced the next-generation z17 mainframe computer and the acquisition of data and artificial intelligence consulting firm Hakkoda.

IBM called for over $13.5 billion in 2025 free cash flow, similar to a projection from April. The company still sees at least 5% revenue growth at constant currency for the year.

As of Wednesday's close, IBM shares were up 28% so far in 2025, while the S&P 500 index has gained around 8% in the same period.

Executives will discuss the results with analysts on a conference call starting at 5 p.m. ET.
