Management Comments

“With the completion of recent spectrum auctions, carriers are now focused on utilizing small cell architectures and the densification of their networks, which is driving increased demand for our rooftop locations,” said Jeffrey Thompson, President and Chief Executive Officer.  “We are also excited to see Google enter the WiFi cellular model as it will likely spur demand for our network.  Moreover, the addition of LTE-Unlicensed is increasing the value of our beach front rooftops.”

"Our On Net program offering of 100 megabytes of bandwidth for $699 per month continues to gain traction as evidenced by the strong growth in lit buildings and customers," noted Joseph Hernon, Chief Financial Officer. "Our new sales center location in Southern Florida is open and staffed, and we expect that a higher base of experienced account executives will drive growth in the Fixed Wireless segment over the course of the year."

The Company has two reportable segments. The Fixed Wireless segment provides fixed wireless broadband services to commercial customers and delivers access over a wireless network transmitting over both regulated and unregulated radio spectrum. The Shared Wireless Infrastructure segment offers a range of rental options on street level rooftops related to (i) the installation of customer owned Small Cells, (ii) Wi-Fi access and the offloading of mobile data, and (iii) backhaul, power and other related telecommunications.

The Corporate group includes corporate overhead and centralized activities which support our overall operations. Corporate overhead includes administrative personnel, including executive management, and other support functions such as information technology and facilities. Centralized operations include network operations, customer care, and the management of network assets. Corporate costs are not allocated to the segments because such costs are managed on a centralized basis. Management also believes that not allocating these centralized costs provides a better reflection of the direct operating performance of each segment.

Non-GAAP Measures and Reconciliations to GAAP Measures

We use certain Non-GAAP measures to monitor the Company's business performance and that of our segments. These Non-GAAP measures are not recognized under generally accepted accounting principles ("GAAP"). Accordingly, investors are cautioned about using or relying on these measures as alternatives to recognized GAAP measures. Our methods of calculating these measures may not be comparable to similar measures presented by other companies.

A definition of the Non-GAAP measures that we employ, and how we use them to monitor business performance, are as follows:

“Adjusted EBITDA” represents net income (loss) before interest, income taxes, depreciation and amortization expenses, excluding, when applicable, stock-based compensation, deferred rent expense, other non-operating income or expenses, as well as gain or loss on (i) nonmonetary transactions, and (ii) business acquisitions.

“ARPU” refers to the monthly average revenue per user, or customer, being generated from those customers under contract at the end of each indicated period. We calculate ARPU by dividing our monthly recurring revenue (“MRR”) at the end of a period by the number of customers generating that MRR.

“ARPU of new customers” is calculated in the same manner but only includes new customers who entered into contracts during the indicated period.

“Churn” and “Churn rate” refer to the percent of revenue lost on a monthly basis from customers disconnecting from our network or reducing the amount of their bandwidth.

“Corporate” includes corporate overhead and centralized activities which support our overall operations.

“EBITDA” represents net income (loss) before interest, income taxes, depreciation and amortization.

“Net Cash Flows” represents Adjusted EBITDA less capital expenditures.

A reconciliation of non-GAAP measures to GAAP financial measures is as follows (amounts in thousands):
