IBM Q2 FY 2026: Software Growth Continues as Mainframe Purchases Slow

Analyst(s): Futurum Research
Publication Date: July 27, 2026

IBM’s Q2 FY 2026 earnings report shows a business still anchored by software, hybrid cloud, and infrastructure, but exposed to large enterprise license agreement timing and mainframe-linked purchasing behavior. The quarter also shows IBM shifting attention toward AI orchestration, open source security, distributed infrastructure, and sales coverage expansion to improve growth execution.

The News: IBM (NYSE: IBM) reported Q2 FY 2026 revenue of $17.16 billion, up 1% year over year (YoY), which was 1.8% below Wall Street consensus estimates. Software revenue was $7.76 billion, up 5.1% YoY, compared with consensus of $7.99 billion, while Consulting revenue was $5.33 billion, up 0.2% YoY, compared with consensus of $5.39 billion. Infrastructure revenue was $3.84 billion, down 7.4% YoY, compared with consensus of $3.96 billion, and Financing revenue was $186 million, up 12.2% YoY, compared with consensus of $178.6 million. Non-GAAP operating pre-tax income was $3.29 billion, up 2.9% YoY, and non-GAAP operating pre-tax margin was 19.2%, expanding from 18.8% in Q2 FY 2025. Non-GAAP operating net income was $2.79 billion, up 5.3% YoY, and non-GAAP operating diluted earnings per share was $2.93, up 4.6% YoY.

“Although we faced revenue headwinds late in the second quarter, we continued to focus on the fundamentals of our business, including driving productivity, strengthening our portfolio, and generating free cash flow,” said James Kavanaugh, IBM senior vice president and chief financial officer. “In a quarter like this, it is critical that our financial and operational discipline remains strong and that we continue to invest for growth while returning value to shareholders through our dividend.”

IBM Q2 FY 2026: Software Growth Continues as Mainframe Purchases Slow

Analyst Take: IBM’s Q2 FY 2026 results are less about broad demand erosion and more about spending priority shifts inside large enterprise accounts. The shortfall centered on large capital expenditure-sensitive transactions tied to mainframe and enterprise license agreements, while recurring software continued to grow. The quarter also shows that enterprise AI spending can crowd out adjacent software decisions when customers redirect budgets toward constrained infrastructure supply. IBM now needs to prove that delayed transactions convert and that go-to-market changes can reduce quarter-end concentration.

Software Mix Shows Both Resilience and Exposure

IBM’s software business now has a clearer divide between recurring demand and transactional timing risk. Roughly 80% of annual software revenue is recurring, including Red Hat, HashiCorp, Confluent, subscriptions, support, and consumption-based offerings. That recurring base grew through the quarter, with annual recurring revenue reaching $24.6 billion, up 8% YoY. Red Hat grew 11%, OpenShift annual recurring revenue reached $2.2 billion, and HashiCorp delivered another record bookings quarter. The remaining 20% of software revenue is transactional and tied heavily to mainframe-associated enterprise license agreements, which created the Q2 FY 2026 pressure point when large deals slipped. IBM’s software model is more durable than in prior cycles, but the transactional layer still has enough weight to affect quarterly growth.

Mainframe Incumbency Remains Central

Mainframe performance was the most visible pressure point, with IBM Z revenue down 42% in the quarter against a difficult prior-year comparison. The longer-cycle indicators remain more constructive, as z17 revenue is still nearly 130% of the prior z16 program at the same point in the cycle. IBM also pointed to more than 140 million installed MIPS in the market and said clients representing 85% of installed MIPS are maintaining or growing capacity. The mainframe still runs over 70% of global transaction value, including core workloads in banking, airlines, retail, and other high-dependence sectors. AI also has a role in the platform story, with clients using Spyre and watsonx Code Assistant for Z showing faster MIPS capacity growth. The risk is not rapid mainframe displacement, but uneven timing in how clients fund hardware, software, and capacity upgrades.

AI, Security, and Consulting Demand

IBM’s AI positioning is strongest where enterprise clients need orchestration, governance, data control, and workload placement flexibility. watsonx Orchestrate, Red Hat, Confluent, Concert, and Bob give IBM an enterprise AI stack that connects application development, data movement, operations, and agent management. Consulting also showed better forward indicators, with signings up 6% and generative AI representing about 50% of signings in the quarter. Generative AI now accounts for more than 30% of consulting backlog, suggesting client demand is moving beyond pilots and into process redesign. Lightwell also creates a new open source security opportunity, with more than 7,500 package versions made available in the first two weeks and early adoption across major financial institutions. IBM’s best path is to connect AI deployment, open source security, and hybrid operations into repeatable enterprise buying motions.

Guidance and Final Thoughts

IBM now expects FY 2026 constant currency revenue growth of 4% to 5%, down from its prior outlook of more than 5%. Software revenue is expected to grow 6% to 8% for FY 2026, with the lower end assuming recent enterprise spending dynamics persist and the higher end assuming a more typical pipeline conversion pattern. Infrastructure is expected to grow low single digits for FY 2026, supported by Power and Storage demand, distributed infrastructure growth, and continued z17 program strength. Consulting revenue is expected to accelerate to low to mid single-digit growth for FY 2026, supported by backlog quality and generative AI demand. IBM continues to expect full-year free cash flow to increase by about $1 billion YoY and now expects 100 basis points of operating pre-tax margin expansion.

IBM’s quarter reinforces that its growth profile increasingly depends on expanding recurring software and AI-led services while reducing the earnings impact of large, transaction-driven businesses. The resilience of Red Hat, recurring software, and consulting signings suggests customer engagement remains healthy, but delayed enterprise license agreements and mainframe purchasing decisions continue to create quarterly volatility. The next phase of IBM’s execution will hinge on whether AI orchestration, hybrid cloud software, and security offerings can become sufficiently large to offset the cyclicality of infrastructure purchases and deliver more consistent growth across business cycles.
