Key Terms

dark fiber, hyperscalers, joint venture, route diversity

4 terms

dark fiber technical

"SummitIG, the premier pure-play dark fiber provider with unmatched network quality"

Dark fiber is unused or unlit optical fiber cable installed in the ground or buildings that can carry data but currently has no active equipment powering it. Investors care because it’s a physical, long-lived infrastructure asset that can be leased or activated to quickly expand network capacity without laying new cable, offering steady, contract-based revenue potential but also requiring upfront capital and facing technology and demand risks.

hyperscalers technical

"we are giving hyperscalers, carriers and large enterprises greater flexibility"

Hyperscalers are large technology companies that operate massive computing networks and data centers to provide cloud services, data storage, and online infrastructure at an enormous scale. They are essential to the digital economy because they enable businesses and organizations to handle vast amounts of data and run complex applications efficiently. For investors, hyperscalers represent powerful engines of growth and innovation in the technology sector.

joint venture financial

"the recent establishment of SierraIG, a strategic joint venture extending its infrastructure"

A joint venture is when two or more companies team up to work on a specific project or business idea, sharing both the risks and the rewards. It’s like friends starting a lemonade stand together—each contributes resources and they split the profits, making it easier to succeed than going alone.

route diversity technical

"adds critical network density and route diversity across Northern Virginia and Maryland"

Route diversity means having multiple, separate physical paths for moving data, power, or goods so a single break or blockage won’t stop service. Like a store with several different roads in and out, it reduces the chance of outages, delivery delays or regulatory breaches, which matters to investors because it protects revenue, lowers operational risk and preserves a company’s reputation and long‑term value.

Strategic acquisition adds critical network density and route diversity across Northern Virginia and Maryland, reinforcing SummitIG's position as the leading digital connectivity partner

STERLING, Va., June 30, 2026 /PRNewswire/ -- SummitIG, the premier pure-play dark fiber provider with unmatched network quality and scale for data center connectivity solutions, today announced it has completed the acquisition of Dark Fiber and Infrastructure, LLC ("DF&I") from funds managed by Blue Owl Capital Inc. ("Blue Owl") (NYSE: OWL), a leading alternative asset manager. SDC Capital Partners, LLC ("SDC"), a leading digital infrastructure investment firm, has been the majority owner of SummitIG since 2019.

The move further solidifies SummitIG's position as the definitive market leader for dark fiber infrastructure across Virginia and broadens its strategic reach into the burgeoning Maryland market.

Complementing SummitIG's existing footprint of over 1,100 miles of robust, high-capacity dark fiber infrastructure in Virginia, the acquisition integrates nearly 200 miles of DF&I's conduit and dark fiber assets into SummitIG's expansive platform. The newly combined footprint provides customers with unparalleled route diversity and density in Virginia and connects nearly 60 miles of distinct network into Maryland, stretching to Baltimore.

"As a leading infrastructure provider of dense, purpose-built dark fiber networks, SummitIG has established a strong track record of execution, and this acquisition represents a significant milestone in our strategy to expand and strengthen our platform in the markets that matter most to our customers," said Sunny Kumar, CEO of SummitIG. "By integrating DF&I's complementary network into our existing broad footprint, we are giving hyperscalers, carriers and large enterprises greater flexibility, deeper route diversity and the additional capacity required to support the next generation of cloud and AI workloads. We are hitting the ground running to ensure a seamless transition and unlock new opportunities for our combined customer base."

This transaction comes during a period of significant growth for SummitIG, with rapid expansion ongoing across five core domestic markets and the recent establishment of SierraIG, a strategic joint venture extending its infrastructure capabilities into Mexico.

"As global demand for cloud computing and next-generation infrastructure accelerates, specialized digital infrastructure assets have never been more critical," said Chris Jensen, Managing Director, Digital Infrastructure at Blue Owl. "We are incredibly proud of the scaled platform we built alongside DF&I's leadership over the last six years. SummitIG is the ideal successor to take these assets forward, and we are confident that their operational expertise and market momentum will drive continued success and infrastructure excellence across the region."

DF&I was previously a portfolio company of the Blue Owl Digital Infrastructure platform, which supported the company's regional buildout and grew the network's reach sixfold over a six-year period. SummitIG is executing a comprehensive integration plan to seamlessly transition customers, operations and network asset information, while completing any remaining active construction projects to ensure continuity for current contract commitments.

Skadden, Arps, Slate, Meagher & Flom LLP served as legal advisor to SummitIG for the transaction. Bank Street Group served as exclusive financial advisor and Akin Gump Strauss Hauer & Feld LLP served as legal advisor to DF&I in connection with this transaction.
