CONSTELLATION ANNOUNCES THE RETIREMENT OF DEXTER SALNA

Constellation Software Inc.'s Dexter Salna will retire effective Dec. 31, 2023.

Perseus is one of the six operating groups within Constellation Software. Mr. Salna will continue to serve on the board of Perseus, along with Mark Leonard and Bernie Anzarouth. Mr. Salna will also continue as a member of the board of directors at CSI.

Mark Leonard, president of Constellation Software, commented: "In 1995, Dexter Salna was one of the original employees of Constellation. During the intervening 28 years, he has helped to build Constellation, has pioneered a number of its best practices and, due to his consistent annual share purchases, has become one of our largest shareholders.

"Dexter was the chief executive and architect of Perseus and its predecessors. He founded the group with a 40-employee, Toronto-based acquisition in early 2004. The group has completed more than 50 acquisitions, has over 4,000 employees and manages a half billion dollars of CSI's capital.

"With Dexter's continued service on the CSI and Perseus boards of directors, we hope to be able to benefit from Dexter's wisdom and experience for many years to come."
