IBM (NYSE:IBM) software hits $7b, but consulting slowdown keeps investors cautious

Red Hat and data growth shine, but the stock still slips

Before we dive into the quarterly update, a little context on IBM worth appreciating.

This is a 115-year-old technology company, and that alone is a rare phenomenon. The average technology company lifecycle is just 20 years. IBM has not only survived that window multiple times over, it has reinvented itself along the way, most recently pivoting into hybrid cloud and now planting its flag firmly in AI infrastructure.

That kind of staying power does not happen by accident, and it is a big part of why we are paying attention here.

Three Business Segments

Today, IBM sits at the backbone of the global economy, helping the world’s largest banks, governments, and hospitals run their most critical technology systems.

IBM operates across three core business segments.

Software is the crown jewel, pulling in $7 billion this quarter, roughly 40% of total revenue. It is IBM’s fastest growing and highest margin segment, housing Red Hat, an open source cloud platform, alongside automation tools and data management. This is where the compounding value lives.

Consulting came in at $5.3 billion, representing 33% of revenue. Growth here has slowed, and frankly, that is not surprising. The conversation around AI displacing traditional consulting roles is real, and it is putting pressure on both growth and fees across the industry.

Then there is Infrastructure, the segment worth watching closely right now given the AI buildout cycle we are in. Think of it as the flywheel that keeps everything else spinning. The hardware acts as an anchor, locking clients into IBM’s software ecosystem for decades. Once they are in, they stay in.

Broad-Based Acceleration

So what happened this quarter? IBM delivered $15.9 billion in Q1 2026 revenue, up 9%, the strongest Q1 the company has posted in years. Yet the stock fell 7% on the print, which opened up an interesting conversation.

Software grew 11%, with Data up an impressive 19% and Hybrid Cloud (Red Hat) up 13%. Here is why that matters. Software carries gross margins of 82%. Growth in this segment does not just add revenue, it drops through to margins and profitability at a rate most businesses would envy. Pricing power at that margin profile is a real competitive advantage.

Infrastructure is a naturally cyclical segment, and right now the cycle is working in IBM’s favour. We are seeing infrastructure revenues surge across the board, and IBM is a direct beneficiary. Our read is that this cycle has more room to run. As infrastructure build-out continues, watch how that demand converts into software growth downstream. That is the flywheel at work.

Worth highlighting too, Infrastructure gross margins came in at 56%, up from 52% last year. That improvement tells us the segment is not just growing, it is growing more efficiently. That trajectory matters.

Margins Expanding at Every Level

Stepping back and looking at the business holistically, gross margins sit at 56% and EBIT at 8.7%. As the product mix continues to deepen toward software and infrastructure, we are seeing margin improvements across the board.

The Infrastructure segment is the standout. Margins jumped from 8.6% to 15.8%, nearly doubling year-over-year. The IBM Z mainframe upgrade cycle is the driver here. Z systems carry significantly higher margins relative to Distributed Infrastructure and Support, and with Z revenue up 51% in Q1, that mix shift is flowing straight through to profitability.

Return on invested capital is trending in the right direction, and that is a healthy sign. That said, it is worth being honest with ourselves. A meaningful portion of this margin expansion is being carried by a favourable cyclical period. The tailwinds are real, but they are not permanent, and that is an important distinction to hold onto as we think about what is sustainable versus what is cyclical.

Confluent Acquisition: The Data Streaming Bet

IBM made a significant move this quarter, acquiring Confluent, a commercial business built around an open source data streaming platform. Most Fortune 500 companies already run on Confluent to move real-time data across applications, databases, and AI systems.

The logic behind the acquisition is straightforward. Customers need to move data fast and efficiently, and that is the critical infrastructure layer that modern AI runs on. You simply cannot run AI models on stale data.

Confluent gives IBM a cloud-native, market-leading data streaming platform that plugs directly into watsonx. It fills a genuine gap, solves a real customer problem, and tightens IBM’s grip on the full AI infrastructure stack. The strategic rationale here is hard to argue with.

Is IBM Worth the Investment?

To keep it simple, the valuation really comes down to one question: how long does this AI buildout cycle last?

If capex and demand hold up, IBM is a clear beneficiary and there is upside over the next 2 to 3 years. But let’s be measured about what that looks like. This is not Nvidia. IBM is a large, mature business, and the return profile reflects that.

Infrastructure growth and margin expansion are not permanent. They are cyclical. Overall operating margins are still relatively thin, and if the cycle turns, IBM will feel it. That is the honest risk sitting in the middle of this story.

On balance, this is a hold.
