Pursuant to announcement on March 1, 2022, this press release has been updated from the previously branded “SUPERNAP Italia” to “STACK Infrastructure,” “STACK,” or “STACK EMEA – Italy” to reflect the current branding.

The high voltage transmission to be developed by Sirti will support the growth plans recently announced by STACK, who will provide Sirti with colocation services in its data centers.

Milan - June 8, 2021 - Sirti, innovation hub in the field of network infrastructure development, and STACK Infrastructure (“STACK” or the “Company”), the digital infrastructure partner to the world’s most innovative companies, today announced that they have signed a strategic partnership aimed at creating innovative synergies within their respective areas of expertise.

Specifically, Sirti - through the Sirti Energia business unit - will design, develop, and manage the high voltage line and the high/medium voltage substation that will increase STACK's capacity up to 80 MW, connecting the data center campus directly to the Terna substation. In parallel, STACK will provide its renowned colocation services to support Sirti's critical IT infrastructure in its Milan data centers.

"We are thrilled to expand our data center campus in Italy so that we can continue to support our current and future customers in meeting their digital infrastructure needs," said Sherif Rizkalla, CEO of  STACK EMEA – Italy. “High voltage transmission, which has been part of our campus design plans from day one, will enable that growth, as well as even greater redundancy and reliability. In Sirti we have found an experienced partner with whom we are happy to collaborate. "

"We are particularly proud to have been chosen by STACK for this important innovation project, which aims to support the growth in Italy of a company with a distinctive position in the data center field, thanks to our expertise in integrating diverse technologies and latest-generation digital services for smart management of utilities, "said Roberto Loiola, CEO of Sirti. "At the same time, the agreement signed provides for STACK to become Sirti's privileged partner for colocation needs: we will entrust them with our critical infrastructure, in a digital scenario in which IT and data management will become increasingly sensitive issues, in terms of availability, security, and sustainability."

The project is expected to be completed within a year, coinciding with the development of new data centers announced by STACK in May.
