Overview

Brookfield-backed Data4 is a European data centre operator, which owns and operates highly connected, resilient and sustainable data centre campuses across key regions. The mainly operational data centre portfolio within Data4 is comprised of hyperscale data centres in Paris, Madrid and Milan, with combined capacity of 244 MW.

The investment in Data4 was made by Interogo Holding’s investment fund Inter Infrastructure Capital II (IIC II) and advised by IH Infrastructure Advisors AG. The investment is managed by Inter Fund Management S.A.

Amberside Advisors’ role

Amberside Advisors were tasked with auditing the structurally complex transaction model, featuring a large number of standalone asset-level sites, each feeding into country-level summaries and ultimately rolling up into a consolidated portfolio valuation. With multiple layers of logic, including four tax jurisdictions, the audit of this model was non-standard and required a well-considered and executed plan to ensure each aspect of the model was captured.

Outcome

The financial close was announced on 1 August 2025, with Interogo Holding AG acquiring a significant minority stake in the Data4 portfolio.

“We are pleased to add the Data4 assets to our portfolio. With 244 MW capacity and an experienced management team, the company is well positioned in the digital infrastructure sector. Its high-quality asset base and long-term customer contracts provide solid visibility and stability for the future. We look forward to partnering with Brookfield, Arjun and Data4 management to support the future development of the company”, said Constantin Dogos-Docovitch, Head of IH Infrastructure Advisors.

“Data centres are experiencing remarkable growth, and we at Amberside Advisors are proud to be playing a pivotal role in this vital asset class and transaction. We’re especially pleased with the way our team came together to tackle the complexities of this deal - not only under significant time pressure, but also in navigating the structural intricacies of the financial model. Congratulations and well done to everyone involved in bringing this project to fruition.” added Alan Samuels, Director at Amberside Advisors.
