Lightower Fiber Networks and Sidera Networks said on Thursday they have closed their more than $2 billion merger, first announced last December.
The combined company now goes by the Lightower name and Lightower CEO Rob Shanahan remains at the helm.
Together, Lightower and Sidera create one of the largest metro fiber providers in the United States with a footprint that spans New England, the New York metro region, Philadelphia, Washington, D.C., Virginia and west to Chicago, with connectivity to landing points in London and Toronto.
Services include backup and recovery, content carriage, media distribution, medical imaging, distance learning, and application and cloud connectivity over Ethernet, waves, dark fiber and more. The company connects more than 130 data centers, 115 carrier hotels and central offices, 40 financial exchanges and 18 Lightower colocation centers.
The transaction was led by Boston-based Berkshire Partners. Pamlico Capital, a Lightower investor, and ABRY Partners, a Sidera investor, will remain investors in the new company. Further details of the financial transaction were not disclosed.
