IBM reported third-quarter 2026 revenue of $17.1 billion on 21 October, up 5 percent, or 6 percent at constant currency, and raised its outlook for full-year free cash flow. GAAP earnings per share from continuing operations were $2.31, up 26 percent, and operating earnings per share were $2.95, up 11 percent. Software revenue was $7.8 billion, up 8 percent, consulting was $5.3 billion and flat, and infrastructure was $3.7 billion, up 4 percent. IBM expects constant-currency revenue growth of 4 percent to 5 percent for the year, and now expects free cash flow to increase by more than $1 billion from last year.
The argument that the quarter was a good one rests on acceleration in software and cash. Hybrid cloud revenue, driven by Red Hat, rose 11 percent, data revenue rose 19 percent, and transaction processing rose 9 percent. Distributed infrastructure rose 31 percent, and hybrid infrastructure overall rose 8 percent. The operating pre-tax income margin was 19.3 percent, up 0.7 points, and operating pre-tax income of $3.3 billion was up 9 percent. Net income of $2.2 billion was up 26 percent. Year to date, net cash from operating activities was $11.8 billion and free cash flow was $7.8 billion. Chief Executive Arvind Krishna said clients are deploying what IBM calls super intelligence to transform whole operating models.
The counter-argument is that parts of the portfolio are shrinking and margins slipped. IBM Z, the mainframe line, fell 20 percent, or 19 percent at constant currency, and the automation part of software fell 3 percent. Consulting was flat, up only 2 percent at constant currency, with intelligent operations down 2 percent, and infrastructure support revenue also fell 3 percent. The GAAP gross profit margin was 56.8 percent, down 50 basis points, and the operating gross margin was 58.5 percent, down 20 basis points. GAAP pre-tax income margin fell 30 basis points to 14.6 percent, so most of the 26 percent rise in net income came from below the pre-tax line. Financing revenue was $0.2 billion, down 4 percent. GAAP gross profit was $9.7 billion, up 4 percent, operating gross profit was $10.0 billion, GAAP pre-tax income was $2.5 billion, up 3 percent, and operating net income was $2.8 billion, up 12 percent.
The report matters because IBM is positioning itself as an enterprise software and consulting company, and the split between growing and shrinking businesses shows how far that shift has gone. Software now accounts for 46 percent of revenue, a calculation from the $7.8 billion and $17.1 billion figures, and it grew at a faster rate than the whole company. The company said that its productivity initiatives are driving profit and cash flow growth while it keeps paying a dividend. Investors will watch whether consulting returns to growth and whether the mainframe decline is a pause in a cycle or a longer trend.
IBM beat expectations on growth and raised its cash outlook, with software doing the heavy lifting. The mainframe decline and the flat consulting line are what to watch in the next quarter.
