PHOENIX - Research on how visitors navigated its previous site provided data and insight for the recent redesign of the Pinnacle West Capital Corp Web site. The new site allows investors, financial analysts, the media and job seekers to access more information in fewer clicks.

While the original Web site offered such innovative features as allowing visitors to make stock purchases and file job applications online, the new site presents even more capabilities. Simplified navigation and easy access to company news and information at www.pinnaclewest.com provide:

• General company background information;
• Information for the media, including regulatory filings and news releases;
• Online access to shareholder accounts;
• Investor links including key financial documents and online stock purchases;
• Career opportunities at Pinnacle West and its subsidiaries including its School-to-Work program;
• Subscription opportunities to receive electronic news releases, investor information and statistics; and
• Direct links to the company’s subsidiaries.

The new site was designed in-house, but to ensure the optimum visitor experience, Pinnacle West also worked with Phoenix-based Mighty Interactive, an Internet consulting firm.

Pinnacle West (NYSE: PNW) is a Phoenix-based company with consolidated assets of approximately $8.5 billion. Through its subsidiaries, the company generates, sells and delivers electricity and sells electricity and energy-related products and services to retail and wholesale customers in the western United States. It also develops residential, commercial, and industrial real estate projects.
