CONSTELLATION SOFTWARE INC. ANNOUNCES CONFERENCE CALL TO DISCUSS AI'S IMPACT ON SOFTWARE BUSINESSES

Constellation Software Inc. will host a live shareholder question-and-answer audio webcast on Sept. 22, 2025, at 9 a.m. ET, regarding the impact of artificial intelligence technologies (AI) on software businesses.

Mark Leonard, president of Constellation, said:

"One of our largest shareholders asked CSI for a question-and-answer session regarding AI's impact on software businesses. We felt that the discussion would inevitably turn from the general to the CSI-specific, so we suggested a webcast where all shareholders would be able to pose questions. This is a nice example of an enterprising shareholder catalyzing corporate action that benefits all shareholders.

"AI has created uncertainty for our employees, shareholders and customers. CSI management don't purport to know the future of AI. We have a group of AI specialists throughout CSI. They don't know the future of AI, either. They do, however, help us monitor our AI progress and that of AI generally in our marketplaces. We've asked four of them to join our panel for this discussion. I hope you enjoy the Q&A session and emerge more informed."

To access the call, please dial 1-877-879-1183 (North America toll-free) or 1-412-902-6703 (international) and using conference ID 2442103. A conference operator will create a queue and introduce each questioner. You can also hear the call on-line. A replay of the call can be accessed on-line for 12 months following the call.
