Eurofiber locks in €2.2bn sustainability-linked debt

Eurofiber said it has locked in €2.2bn ($2.56bn) of long-term financing, replacing its €1.5bn facility in a sustainability-linked refinancing that keeps open digital infrastructure inside the infrastructure debt market. The new platform includes significant undrawn committed facilities, making the capital a runway for buildout rather than a one-time payout, and a broad group of banks and institutional investors backed the deal, with Macquarie Asset Management confirming a €125m ($145m) senior term loan piece.

The facility is €700m larger than the one it replaces and arrives as Eurofiber reshapes its asset base: in June, the company agreed to sell four of its French data centers to Etix, an edge data center firm, and in February it acquired Luxembourg-based connectivity provider LuxNetwork. BNP Paribas and Rothschild & Co advised on the financing, with Clifford Chance acting for Eurofiber, Antin Infrastructure Partners and PGGM Infrastructure Fund, leaving the debt platform reset while the portfolio is sold and expanded.

Eurofiber runs a 77,500km fiber network spanning the Netherlands, Belgium, Luxembourg, France and Germany, plus eight data centers in the Netherlands, two of which arrived with the 2024 purchase of Bytesnet. That footprint is the collateral for the refinancing and helps explain the breadth of the lender group: a five-country route with data center attachments is a base lenders can underwrite without depending on one market or one customer.

The transaction is structured as a Sustainability-Linked Loan aligned with the LMA Sustainability-Linked Loan Principles, with annual ESG targets and a margin adjustment mechanism tied to three KPIs: reducing Scope 1, 2 and 3 emissions in line with the Science Based Targets initiative, introducing a circularity KPI, and increasing gender diversity. The announcement does not disclose the specific thresholds, and a margin ratchet tied to unstated targets is easy to announce and hard to audit. Eurofiber's financing partners are underwriting the company's ESG trajectory along with its fiber footprint. Chief executive Alex Goldblum said the refinancing confirms the strength of the model and the confidence of lenders in the long-term strategy; the margin movement in future reporting will show whether the ratchet is doing real work.

Digital infrastructure capital splits between hyperscaler-anchored assets that clear at infrastructure pricing and everything else that fights for capital. Eurofiber is a test of that divide: on its face, this is an open digital infrastructure platform, with no campus anchored to a single hyperscale lease, and it has still priced €2.2bn of long-term debt. The distinction that matters may not be the anchor tenant; it may be the quality of the contracted base and the willingness to tie the margin to ESG targets.

Macquarie's role sharpens the point. A week before this deal, Macquarie sold its Polish fiber networks to Deutsche Telekom for €1bn, and the proceeds were heading into data centers and towers; now Macquarie is on the lender side of a different fiber platform's refinancing, capital recycling running in both directions: exit the mature asset, fund the expander.

The refinancing buys Eurofiber headroom and a larger committed base, and it sets a clean test for sustainability-linked debt in digital infrastructure. The undrawn facilities become useful only if they convert into fiber that earns its cost of capital; the margin ratchet becomes credible only if the KPI disclosures show real movement. On both scores, the next reporting cycle will tell more than the announcement did.
