Summary
- IBM reported second-quarter revenue of $17.2 billion, up 1%, GAAP net income of $2.2 billion and diluted earnings of $2.27 a share.
- Software revenue rose 5% to $7.8 billion; Red Hat grew 11% and Data 19%, while transaction processing declined 8%.
- Consulting revenue was flat at $5.3 billion, and infrastructure fell 7% to $3.8 billion as IBM Z dropped 42% while distributed infrastructure rose 37%.
- Quarterly operating cash flow was $2.6 billion and free cash flow was $2.5 billion, down $0.3 billion; first-half free cash flow was flat at $4.8 billion.
- IBM now expects 4% to 5% full-year revenue growth at constant currency and still expects free cash flow to improve by about $1 billion year on year.
IBM's new outlook is a statement about mix. The company did not produce a broad second-quarter acceleration: reported revenue increased only 1%, consulting did not grow, infrastructure shrank and quarterly free cash flow moved backwards. What changed the full-year range was the expanding part of the portfolio—software—combined with management's view of the remaining pipeline and recent acquisitions.
That distinction matters because a company can improve its recurring-revenue profile while its operating engine remains uneven. The investment case then depends less on one aggregate growth number and more on whether software expansion survives weaker transaction processing, whether consulting demand turns into implementation revenue, and whether acquisition spending produces cash rather than merely enlarging the base.
Software is doing more than its share
Software generated $7.8 billion, up 5%. Within it, Red Hat grew 11% and Data 19%, two signals that hybrid-cloud infrastructure and data tooling continue to attract spending. Those rates give IBM a plausible route to steadier revenue than a hardware-led cycle would provide.
The offset is transaction processing, down 8%. That business has historically carried attractive economics and deep customer dependence. A decline does not erase the installed base, but it shows that recurring characteristics do not make every software line mechanically immune to contract timing, optimization or comparison effects.
Software's strength also should not be confused with proof that every booked commitment has become revenue. Backlog and future obligations can support confidence, but accounting revenue arrives only when the contracted work is delivered. The quarter's $7.8 billion is the recognized result; any unrecognized distributed-infrastructure or software demand remains evidence about the future, not an addition to this quarter.
Hardware has entered the other side of its cycle
Infrastructure revenue fell 7% to $3.8 billion. IBM Z was down 42%, a sharp contraction consistent with the timing of mainframe product cycles. Distributed infrastructure grew 37%, preventing the segment from falling further, but the two movements do not cancel operationally: one is a mature high-value platform resetting after a strong cycle, while the other is demand that still has to establish its durability.
Consulting, at $5.3 billion, was flat. That is important because consulting is one bridge between a software licence or subscription and an enterprise deployment. If clients buy technology but delay transformation projects, IBM may still recognize software growth while losing some of the services pull-through that broadens account economics.
The result is not a collapse. GAAP net income was $2.2 billion and diluted earnings were $2.27 a share. It is an uneven portfolio in which the most predictable-looking line is carrying two businesses with more obvious timing exposure.
The cash test is stricter than the guidance
Quarterly operating cash flow was $2.6 billion and free cash flow $2.5 billion, $0.3 billion below the prior-year period. For the first half, operating cash flow reached $7.8 billion and free cash flow was $4.8 billion, unchanged year on year. Those period boundaries matter: the stronger first-half operating cash number cannot be presented as quarterly cash, and the full-year promise has not yet been earned.
IBM ended the period with $8.2 billion of cash and marketable securities and $62 billion of debt. It had spent $10.5 billion on acquisitions year to date. Acquisitions can increase reported scale, technology coverage and future cross-selling, but the purchase price leaves immediately while integration benefits arrive gradually and uncertainly.
Management now expects full-year revenue to grow 4% to 5% at constant currency, narrowing and lifting the prior framing. Constant currency removes exchange-rate movement so that operating progress is easier to see; it is not the same as reported-dollar growth. The company retained its expectation that free cash flow will improve by about $1 billion from 2025.
That cash commitment is the more useful accountability line. If software growth, consulting conversion and acquired operations lift full-year cash by the promised amount, the mix shift will have created financial capacity. If revenue reaches the range while free cash flow lags, IBM will have purchased or deferred more of the improvement than the headline suggests.
The next quarter should therefore be read across four lines, not one: Red Hat and Data growth, the depth of the IBM Z trough, consulting's return or failure to return to growth, and cumulative free cash flow. A raised constant-currency range earns attention. Only cash conversion can turn it into proof.
