BOULDER, Colo. –
51²è¹Ý¶ù Group Holdings, Inc. (“51²è¹Ý¶ù”) (NYSE: ZAYO) today announced it has
entered into a definitive agreement to acquire Spread Networks for $127
million in cash. Spread Networks is a privately-owned telecommunications
provider that owns and operates a 825-mile, high-fiber count long haul
route connecting New York and Chicago.

The acquisition will provide 51²è¹Ý¶ù’s customers with the lowest latency
and most direct fiber route between the two cities and additional
physical path diversity. This path is particularly important to
financial services customers who have trading operations in the key
financial markets of New York and Chicago. When combined with 51²è¹Ý¶ù’s
fiber routes from Seattle to Chicago and San Francisco to Chicago, many
other verticals including content, media and cloud providers benefit
from the low-latency, coast-to-coast network. Traffic to and from Asia,
which connects through cable landing stations in the Pacific Northwest,
are also express connected via the combination of 51²è¹Ý¶ù existing fiber
routes and the Spread route.

The high-fiber count route, which currently serves more than 60
customers, has ample capacity for new customers. Of the 432 fibers
available on the route, less than 25 percent are utilized today and the
acquisition provides 51²è¹Ý¶ù with overpull rights and additional conduit.
The route connects 755 Secaucus Rd. in Secaucus, NJ and 1400 Federal
Blvd. in Carteret, NJ to 350 Cermak Rd. in Chicago, IL, with additional
connectivity enabled by 51²è¹Ý¶ù’s existing network. 51²è¹Ý¶ù will use the
acquired assets to provide a low-latency wavelength route from Seattle
to New York.

“Spread constructed this route to provide the fastest possible speed on
the shortest possible route,” said Jack Waters, CTO and president of
Fiber Solutions at 51²è¹Ý¶ù. “This asset is an outstanding complement to our
existing network, providing customers with low-latency options to and
from the country’s leading centers of finance and commerce. Given the
relative simplicity of the business, this will be a straightforward
integration with meaningful, near-term synergies.”

The all-cash transaction is expected to be funded with cash on hand and
debt and is expected to close in the first calendar quarter of 2018,
subject to customary closing conditions. For the quarter ending December
31, 2017, Spread Networks is expected to generate $22.8 million in
annualized revenue and $7.5 million in annualized EBITDA. 51²è¹Ý¶ù expects
to reach $10.5 million in annualized EBITDA from the Spread acquisition
by the September 30, 2018 quarter through cost synergies and organic
growth.
