US fiber optic network firm FiberLight has closed a $500 million sustainability-linked refinancing facility.

FiberLight intends to use the capital to refinance existing debt and accelerate strategic initiatives, including organic network expansion and enhanced service delivery for both new and existing customers across enterprise, hyperscale, and government sectors.

The facility was underwritten by JPMorgan Chase Bank and SMBC, and is currently being syndicated to a larger group of lenders.

"This investment represents a major milestone for FiberLight and is a strong indicator of the trust we have established as a brand," said Bill Major, CEO of FiberLight.

"We're not just growing, we're accelerating. With this capital in hand, we're scaling faster, reaching further, and delivering future-ready infrastructure that meets the needs of our customers today and tomorrow. We're here to lead the industry, and we're just getting started."

The loan is tied to certain ESG performance targets, including an expansion into underinvested and high-growth markets, and direct investments into local communities through technological deployments.

“In facilitating this refinancing, we were able to provide FiberLight the capital and flexibility to scale rapidly and advance its business goals. We’re proud to support FiberLight’s continued growth and sector innovation,” said Perry Offutt, chair of FiberLight and partner at Morrison.

FiberLight was founded in 2005 and is headquartered in Atlanta, Georgia. The company has an extensive footprint across the US, operating in more than 430 cities, with approximately 19,000 route miles of fiber networks and 230,000 pre-qualified near-net buildings. The company was acquired by a consortium led by Morrison in 2023 for a reported $1 billion.

Last month, the company agreed a deal to acquire Metro Fiber Networks, a fiber network firm based in Virginia. The deal is expected to close in Q2 2025.
