Constellation Software Bets AI Won’t Break Its Software Model

Constellation Software is trying to reassure investors that it can handle the growing disruption artificial intelligence may bring to the software industry. On its latest earnings call, president and CEO Mark Miller said the company is taking AI very seriously, but believes it is in a strong position because its businesses are built on something deeper than just coding speed. Constellation owns hundreds of software companies serving niche industries with mission critical products, including areas such as public transit and golf operations. Miller argued that its long developed strengths, including vertical market expertise, deep understanding of customer workflows, valuable data inside its systems, and trusted client relationships, will matter more than simply building features faster.

That message comes at a time of real investor anxiety. Constellation has long been viewed as one of Canada’s most reliable technology companies, but its stock has fallen about 38 percent over the past 12 months as markets struggle to judge how AI will reshape software. At first, AI was seen as a benefit because it could help developers work more efficiently. Now, many investors worry it could weaken the traditional software as a service model by reducing the number of licenses companies need, making it easier for startups to compete, and allowing customers to create more of their own tools. Miller acknowledged the uncertainty, but said Constellation has not seen meaningful revenue erosion from AI so far, nor has it yet seen major new revenue directly generated by AI products.

Inside the company, Constellation has spent the past year helping its businesses navigate this shift. Miller said thousands of developers have been upskilled in AI enabled coding, and internal AI accelerator programs are being used to spread best practices across the company’s portfolio. Those efforts include programs involving operating groups such as Volaris, Harris, Vela, Jonas, and others. Management says the productivity gains are real and still increasing, but it is not treating them as a quick source of higher profit margins. Instead, the plan is to reinvest those gains into faster product development and broader product roadmaps. Miller said that in the long run, building features faster will become standard across the industry, so the real competitive edge will come from domain knowledge, customer trust, and what he described as emerging knowledge networks that connect expertise, process understanding, and data.

Constellation is also changing how it thinks about acquisitions. Its overall capital allocation process remains mostly the same, but it now includes an explicit AI lens to assess both disruption risk and AI upside for each target. The company is also piloting AI tools to help rank acquisition prospects by quality and readiness to transact, though Miller said it is still too early to know whether those tools will prove valuable over time. In 2025, Constellation completed acquisitions totaling $1.579 billion and made net investments of $530 million, including in Asseco Poland. Since Dec. 31, it has also completed or committed to additional deals worth $802 million.

A major strategic shift is the formal launch of Constellation’s permanent engaged minority shareholder strategy, or PEMS. Rather than replacing its usual practice of acquiring companies outright, this approach gives the company another way to deploy capital in larger businesses it may not be able to buy entirely. The first major example is Sabre Corp., where Constellation owns a 12.7 percent stake and secured board representation through Damian McKay of Vela Software. Miller emphasized that this is an evolution, not a change in direction, and said the company will pursue minority stakes rationally without letting them become a distraction.

Financially, the company reported fourth quarter revenue of $3.2 billion, up 18 percent from a year earlier, while full year revenue rose 15 percent to $11.6 billion. Organic growth slowed from 3 percent to 2 percent, and full year profit fell 30 percent, adding to concerns. Even so, some analysts believe the selloff has gone too far. With Mark Miller now leading more publicly after founder Mark Leonard stepped down as president last year for health reasons, Constellation is presenting itself as a disciplined software consolidator that sees AI as a major challenge, but not one that will force it to abandon the strategy that built the company.
