European datacentre operator maincubes, which is majority owned by DTCP, has secured E2.475bn (US$2.89bn) in platform-level debt financing to refinance its portfolio and fund growth across Europe, according to a press release from DTCP. 

The financing includes E1.775bn of committed facilities and a further E700m uncommitted accordion, provided by a consortium of 11 banks - with MUFG, UniCredit, and ING confirming their participation in LinkedIn posts. Proceeds will be used to refinance existing assets and support the development of new datacentre projects, the release said.  

The funding will support construction of maincubes’ fourth Frankfurt datacentre, known as FRA04, development of a planned 200MW Berlin mainHub campus, and expansion options and upgrades across existing operational sites, the release added. 

While this story has now broken to the public, TMT Finance subscribers had exclusive access to our reporting from January 2025, giving them early knowledge of the deal and the opportunity to track how it evolved –  a full year in advance:

​

maincubes operates a platform of around 400MW across Germany and serves public sector customers and global hyperscalers, the release noted. The company was advised on the financing by RBC Capital Markets, which TMT Finance originally reported in June 2025, and A&O Shearman, while the financing consortium was advised by Hogan Lovells. 

In November 2025, TMT Finance exclusively reported that the refinancing and capex raise for maincubes had been upsized to about E1.8bn, comprising an amend-and-extend of the E685m financing maincubes had secured in March 2023 to raise an additional E1.1bn of capex. The transaction was being priced at an average margin of around 270 basis points, with sources adding that the debt carried a leverage ratio of between 12x and 13x. Several banks were participating in the debt raise, which sources said was expected to reach financial close by the end of December 2025. 

TMT Finance reported in October 2025 that RBC had launched a E1.6bn debt refinancing and capex raise to the market. We reported in June 2025 that RBC had taken up the mandate on the refinancing from the previous adviser. 

TMT Finance also reported in January that the transaction centred on a E1.035bn financing package secured in March 2023, comprising E685m of committed facilities and a E350m uncommitted accordion. The March 2023 loan was provided by a consortium of eight banks and one institutional fund, with maincubes advised by Perella Weinberg Partners’ debt advisory team and Allen & Overy, and the financing consortium advised by Hogan Lovells, per an announcement at the time.
