BOULDER - Bandwidth infrastructure provider Zayo Group LLC on Friday reported revenue of $273.6 million for the company's second fiscal quarter ending Dec. 31.

The revenue marked an increase of $28.3 million compared with the same period a year ago. But net loss also increased, from $34.2 million to $36.3 million.

Boulder-based Zayo said in a press release that the revenue growth, which increased nearly $10 million compared with the previous quarter, was due "largely to a function of organic growth associated with positive net installations, and to a smaller extent, acquisition-related growth."

The net loss, which increased by $8.4 million compared with the previous quarter, was related to a $14 million jump in stock-based compensation expense.

Zayo Group has grown rapidly, acquiring several fiber-networking companies, and there has been speculation recently that Zayo could be primed for an initial public offering sometime this year.
