Igneo expands digital infrastructure footprint with acquisition of Vault Digital, a c. 75 MW U.S. wholesale data center portfolio
All Press releasesNEW YORK, February 5th 2026: Igneo Infrastructure Partners (“Igneo”), a global infrastructure investment manager with $23 billion in assets under management, today announced that it has acquired an approximately 75 MW, 750,000 sf, portfolio of seven operational data centers across key US markets from CVC DIF and Northleaf Capital Partners.
The portfolio, which will operate as Altum Digital Infrastructure (“Altum”), is made up of data centers strategically located in high-growth digital infrastructure markets including Phoenix (AZ), Richardson (TX), Santa Clara (CA), Charlotte (NC), Clarksville (VA), Hazelwood (MO), and Indianapolis (IN). These locations are characterized by low vacancy rates and high barriers to entry. In addition to currently providing critical capacity for blue-chip tenants under long term leases, Altum has a secured expansion plan to scale capacity within 18 months. The portfolio’s largest asset is located in Phoenix, Arizona, with more than 24 MW of utility power, offering customers capacity, reliability, and speed to market for enterprise applications.
Altum will be led by Timothy Doherty, Chief Executive Officer, and Chris Kent, Chief Operating Officer, seasoned executives with decades of experience in data center operations, energy, logistics, and large-scale project delivery. Their leadership, combined with Igneo’s capital and long-term investment approach, positions Altum as a trusted partner for organizations navigating cloud and digital transformation.
“The data center sector is experiencing rapid growth as organizations expand their data and compute capabilities,” said Michael Ryder, Partner and Co-Head of North America. “This transaction reflects our focus on acquiring mid-market platforms with growth capacity and strong downside protection. Altum is exceptionally well positioned to serve high-quality tenants in supply-constrained markets. We look forward to partnering with Altum’s management team whose proven track record and expertise will be the cornerstone of driving the next phase of growth for the company.”
“Igneo’s long-term investment approach and deep digital infrastructure expertise make them the ideal partner as we continue to meet the evolving needs of hyperscale and enterprise clients,” said Doherty. “Altum’s strong foundation of secured power, strategically located facilities and a clear path to expansion, provides customers an outstanding runway for growth.”
Altum is Igneo’s third investment from its dedicated North American infrastructure strategy. Since 2020, Igneo has deployed c. $3.5 billion in the United States across digital, transportation and energy infrastructure sectors. Financial details of the transaction were not disclosed.
Wells Fargo and BofA Securities served as Co-Financial Advisors and Co-Lead Arrangers on the financing supporting the transaction, highlighting robust institutional backing for Igneo’s digital infrastructure expansion strategy. Gibson, Dunn & Crutcher LLP acted as legal advisor to Igneo.
