Vesta Software Group Limited
Year Ended 31 December 2025

Constellation Software UK Holdco Limited and its UK subsidiaries operating under the Vesta
Software Group are committed to preventing modern slavery and human trafficking in all areas
of our business and supply chain. We take this responsibility seriously and continue to
strengthen our approach each year.

Who We Are
Vesta is a group of 22 UK businesses. While each business operates independently, core
functions such as HR, IT and Finance are centralised to ensure consistent standards and strong
governance.

Our People
We consider the risk of modern slavery within our own workforce to be low. All employees,
contractors, and agency workers are engaged through controlled processes that include
right-to-work checks, standardised contracts, and clear policies on ethical conduct, equality,
and whistleblowing.

Our Supply Chain
Our supply chain includes technology, hosting, hardware, and professional services suppliers.
Most are based in the UK and Europe, but we recognise that some categories particularly
hardware and suppliers operating in higher-risk regions require closer scrutiny.

To improve visibility and oversight, we are implementing a centralised supplier management
system and strengthening our due-diligence processes across all businesses.

Our Actions
During the year, we:

• – Built a central database of suppliers across the Group
• – Introduced a risk-based assessment process for new and existing suppliers
• – Began issuing enhanced questionnaires to higher-risk suppliers
• – Developed a Supplier Code of Conduct outlining our minimum labour standards

Our Commitment
We remain committed to:

• – Improving visibility of our supply chain
• – Strengthening supplier assessments and monitoring
• – Ensuring all suppliers meet our minimum standards
• – Protecting the rights and well-being of everyone connected to our operations
