SummitIG announced that it has completed the acquisition of Dark Fiber and Infrastructure from funds managed by Blue Owl Capital. Financial terms of the transaction were not disclosed.
SummitIG is a pure-play dark fiber provider focused on data center connectivity solutions. SDC Capital Partners has been the majority owner of SummitIG since 2019.
The acquisition strengthens SummitIG’s position in dark fiber infrastructure across Virginia and expands its reach into Maryland. The deal adds critical network density and route diversity across Northern Virginia and Maryland.
SummitIG’s existing footprint includes more than 1,100 miles of high-capacity dark fiber infrastructure in Virginia. The acquisition adds nearly 200 miles of DF&I conduit and dark fiber assets to SummitIG’s platform.
The combined footprint provides customers with deeper route diversity and density in Virginia. It also adds nearly 60 miles of distinct network into Maryland, extending to Baltimore.
SummitIG said the expanded network will support hyperscalers, carriers, and large enterprises. The company expects the added capacity and route diversity to help customers support next-generation cloud and AI workloads.
The transaction comes during a period of growth for SummitIG. The company is expanding across five core domestic markets and has recently established SierraIG, a strategic joint venture that extends its infrastructure capabilities into Mexico.
DF&I was previously a portfolio company of Blue Owl’s Digital Infrastructure platform. Blue Owl supported DF&I’s regional buildout and helped expand the network’s reach sixfold over six years.
SummitIG is implementing an integration plan to transition customers, operations, and network asset information. The company also plans to complete the remaining active construction projects to ensure continuity for current contract commitments.
Skadden, Arps, Slate, Meagher & Flom served as legal advisor to SummitIG. Bank Street Group served as exclusive financial advisor to DF&I, and Akin Gump Strauss Hauer & Feld served as legal advisor to DF&I.
SummitIG designs, builds, and operates purpose-built fiber networks for the digital economy. Its infrastructure platform serves hyperscale cloud providers, carriers, data center operators, and enterprises.
SDC Capital Partners is a global digital infrastructure investment firm with about $12 billion in assets under management. Blue Owl is an alternative asset manager with $315 billion in assets under management as of March 31, 2026.
