Rowan Street Capital, LLC on Constellation Software Inc.
Thesis
Rowan Street initiated Constellation Software in the first quarter of 2026 after years of experience owning Topicus. The fund is attracted to a record of approximately 28% annual compounding in shareholder capital since the 2006 listing, supported by a decentralized acquisition model and disciplined reinvestment. First-quarter revenue rose 20%, free cash flow available to shareholders grew 44%, and the company deployed a record $766 million into acquisitions. Rowan Street believes the mission-critical nature of its vertical-market software and deeply embedded customer workflows make the portfolio more durable against AI disruption than the market assumes, while the decentralized system is designed to survive beyond founder Mark Leonard.
“We believe the enduring value of Constellation lies not in one individual, but in the decentralized system he spent decades building.”
Key risks
- Artificial intelligence may disrupt portions of the vertical-market software portfolio.
