Yondr Group Secures £532m ABS for London Campus

Yondr Group – a developer, owner and operator of hyperscale data centres – has priced £532m (US$670m) in securitised term notes, marking its debut in the public capital markets. 

The transaction also represents Yondr’s first bond under its Green Finance Framework, supporting campus development and long-term capital strategy.

The notes refinance part of Yondr’s 100MW+ campus in Slough, one of Europe’s largest data centre hubs. 

The campus comprises three data centres located near London. 

The first and second buildings are fully operational, delivering more than 60MW of capacity.

The ABS transaction covers these two buildings on the Slough campus.

Both buildings maintain a strong track record of operational excellence and service-level compliance, maintaining industry-leading reliability for mission-critical workloads. 

A third building is currently under construction and will become operational later this year, further strengthening Yondr’s presence in the region.

Green bond designation

The transaction achieves a green bond designation via a Second-Party Opinion from Morningstar Sustainalytics, confirming alignment with Yondr’s Green Finance Framework. 

This framework meets the core components of the Green Bond Principles 2025 and the Green Loan Principles 2025.

Sandip Mahajan, CFO at Yondr, says: “Securing our first ABS financing marks a major milestone in diversifying Yondr’s capital strategy and reflects the strength of our asset base and capability of our team.

“This transaction not only diversifies our capital structure but also reinforces our commitment to supporting the continued build‑out of Europe’s digital infrastructure. 

“As we scale our portfolio, it is essential that our approach to financing continues to evolve in both its structuring and its alignment with our environmental ambitions.”

Legal and financial advisers

Yondr is represented by Linklaters LLP as Issuer Counsel. Latham and Watkins act as Underwriters Counsel. 

Barclays is leading the transaction as Sole Structuring Advisor and Sole Green Structuring Coordinator, with Goldman Sachs acting alongside Barclays as Joint Lead Managers and Joint Bookrunners.

Additional support has come from ABN AMRO, Deutsche Bank, Nomura and Société Générale as Co-Managers.

The involvement of these firms supports Yondr’s debut in public capital markets and its ability to execute structured financing for its data centre campus. 

The Slough campus, with more than 100MW of potential capacity, remains a central focus for the company’s operational and financing strategy.

Campus expansion and operations

Yondr continues to expand its London-area campus while maintaining high operational standards. 

The first two buildings deliver reliable service for mission-critical workloads, demonstrating the company’s ability to operate at scale.

The third building, currently under construction, will increase total campus capacity once operational later this year, further enhancing Yondr’s footprint in one of Europe’s key data centre hubs.

The Green Finance Framework ensures that all financing aligns with sustainability targets, including net zero emissions, reduced water use and improved cooling efficiency. 

Allocation and impact reporting are maintained across all sites, reflecting Yondr’s commitment to transparent and responsible capital deployment.

The ABS financing marks both a financial and operational milestone, supporting continued campus growth while linking capital to measurable environmental objectives.

Looking ahead

As hyperscale data centre demand continues to grow across Europe, campuses like Yondr’s Slough site are positioned to play an increasingly important role in supporting digital infrastructure. 

Operators are expanding capacity while maintaining reliability for mission-critical workloads and the integration of green finance frameworks highlights the industry’s focus on sustainability. 

Transparent reporting, energy efficiency improvements and water reduction strategies are expected to remain key priorities as data centre campuses evolve to meet both environmental standards and the rising needs of cloud and enterprise services.
