RCN Corporation Minimizes Costs, Identifies Market Penetration Opportunities with Hyperion Business Performance Management Solutions

SUNNYVALE, Calif., October 8, 2002 — Nothing is more important to today's integrated communications service providers than reducing costs and growing market share. RCN Corporation (Nasdaq: RCNC) is accomplishing both of these goals with its use of business performance management solutions from Hyperion (Nasdaq: HYSL). Since implementing Hyperion applications last year, New Jersey-based RCN has been able to leverage more immediate and accurate performance information, resulting in increased productivity, cost savings and enhanced customer service. In addition, the analysis delivered through Hyperion solutions has allowed RCN to identify new market opportunities and quickly take action to grow revenue.

"Hyperion delivers the valuable information we need to identify new markets, potential market sizing and penetration rates," said Ernest Iocca, senior system developer and administrator for RCN Telecom Services. "With this analysis at our fingertips we can make strategic decisions about staffing, promotions and inventory related to each of our regions. By reducing our inventory costs and improving growth opportunities we have already seen significant return on our Hyperion investment."

To Market, To Market
Hyperion provides RCN with a combination of cost-saving benefits and market growth opportunities. Rather than relying on spreadsheets and time-intensive manual calculations, RCN taps Hyperion's planning capabilities for timely information and analysis about the market penetration rate and number of marketable homes in a region. This allows RCN to make fast decisions about where to deploy sales teams, when to increase aggressive promotions and where to upgrade technology.

At the same time, RCN has improved its budget and forecasting processes using Hyperion applications. These applications allow managers to make adjustments that are reflected immediately at any point during the budget cycle. This provides more accurate forecasts and makes managers more accountable for their figures, which is fundamental to achieving increased effectiveness. RCN management now can easily track which regions are ahead or behind on budgets and quickly determine if problems exist in the field that might have gone undetected.

"Business performance management is about much more than tracking financial performance," said Nazhin Zarghamee, chief marketing officer for Hyperion. "Hyperion business performance management solutions allow leaders like RCN to identify opportunities for growth and take immediate action on critical information. This not only drives profitability, but leads to greater customer, shareholder and employee satisfaction."

All Paths Lead to the Customer
A key part of RCN's business involves managing the growing inventory of cable television converter boxes or high-speed Internet access devices. With the cost and performance data captured in Hyperion applications, RCN has been able to increase enterprisewide visibility into the utilization rate of these boxes, significantly reducing excess inventory costs and streamlining management of rentals and returns. With Hyperion's business performance management solutions, RCN has simplified its billing data across each region, resulting in more accurate invoices and decreased customer inquiries. While RCN is improving productivity and reducing costs, in the end the customers realize the greatest benefit.

"Hyperion makes us all aware of what is behind our budgets and our market growth plans," said Iocca. "Now we can analyze those numbers, track the trends and quickly make adjustments along the way."
