Yellow Pages Publisher R.H. Donnelley Selects Hyperion to Help Manage, Measure and Report Business Performance.

SUNNYVALE, Calif. -- Leading Yellow Pages Publisher and Directional Media Company Extends Reporting and Forecasting Power to Users at Multiple Locations via the Web

When one of the nation's leading yellow pages publishers and directional media companies decided to extend reporting and forecasting capabilities to staff at two locations, it selected Hyperion (Nasdaq:HYSL), the global leader in Business Performance Management software, to deliver a solution. R.H. Donnelley Corporation (NYSE:RHD) chose Hyperion Financial Management to provide centralized external management and cost center reporting as well as to extend reporting power to employees across its divisions.

Hyperion will provide Web-based Business Performance Management capabilities to executives and staff at R.H. Donnelley's primary operating facilities in its Cary, N.C., headquarters region, as well as its office in Overland Park, Kan. In addition to enabling R.H. Donnelley staff to input, manage and monitor its own forecasting information, the solution will allow access to integrated performance data from the company's existing data sources to provide senior management with actionable information for decision making.

R.H. Donnelley publishes 389 directories and serves more than 260,000 local and national advertisers. The company plans to roll out the Hyperion solution to an initial selection of executives and staff before introducing it to a wider employee user group.

"We are experiencing rapid expansion as a result of our recent acquisition of SBC's communications directory publishing business in Illinois and northwest Indiana, and our acquisition of Sprint's directory publishing business last year," said Alan Rupp, director of financial planning and analysis for R.H. Donnelley. "With its industry experience, proven solutions and market leadership, Hyperion is the natural choice to support R.H. Donnelley's continued growth. Hyperion Financial Management provides us with a centralized, unified view of our overall performance, as well as increased ability to provide additional control, responsibility and decision-making power to our divisions."

The first phase of R.H. Donnelley's two-phase implementation project was completed in September 2004. During the second phase, Hyperion Analyzer will be used to develop a dashboard interface that further speeds and streamlines access to performance information and reports.
