Constellation Kidney Group (CKG), a global portfolio of businesses under Miram Solutions within the Perseus Operating Group (Perseus) of Constellation Software Inc. (TSX: CSU), proudly commemorates 50 years of dialysis technology innovation, honoring the legacy of Quantitative Medical Systems Inc. (QMS), founded in Oakland, California in 1976. Acquired by Perseus in 2013, QMS laid the foundation for what is now a global leader in integrated clinical, operational, and analytics solutions for kidney care providers.

To mark this milestone, CKG is unveiling a refreshed brand identity and introducing its next-generation product ecosystem:

• KidneyOne, a fully integrated dialysis management platform;
• CKG Intelligence, a powerful analytics suite, including the Renal AI predictive care solution; and
• CKG Exchange, a robust interoperability hub for the future, connecting data across the kidney care continuum.

"Celebrating 50 years is a testament to the incredible legacy of QMS and the ongoing commitment of Constellation Kidney Group to empower dialysis providers with technology that makes a meaningful difference," said David Abbott, General Manager of CKG. "As part of the Constellation Software family, our ethos has always been to acquire and nurture vertical market software businesses for the long term, ensuring continuous innovation and lasting value for our customers."

CKG’s KidneyOne platform brings together its market-leading solutions into a single, unified ecosystem — enhancing workflows, delivering actionable insights, and helping dialysis providers optimize care, operations, and compliance across global markets.

“KidneyOne gives providers a smarter, more connected way to run their dialysis operations while supporting better outcomes and reducing costs,” said Chris Lutz, General Manager, CKG US. “By uniting best-in-class solutions with AI-driven analytics and integrated workflows in a single platform, we’re defining the next generation of dialysis software built to scale for long-term growth.”

The 50th anniversary milestone reflects CKG’s enduring mission to advance kidney care through purpose-built technology, reliability, and long-term partnership. Visit the company’s updated website to learn more: www.constellationkidney.com
