SANTA CLARA, Calif., April 9, 2007 -- Hyperion (Nasdaq Global Select: HYSL), the global leader in Business Performance Management (BPM) software, joins 33 of its own customers on a new list of America’s 100 most trustworthy companies recently published online by Forbes magazine. The listing highlights companies that “showed the highest degree of accounting transparency and fair dealings to stakeholders” in 2006, and spotlights only two other software companies besides Hyperion.

The list was compiled by Audit Integrity, an independent firm that conducts research on corporate governance and supplies related data to Forbes.com. The full list is available at http://www.forbes.com/2007/03/26/companies-accounting-governance-lead- cx_pm_0327trustyintro.html (Due to its length, this URL may need to be copied/pasted into your Internet browser's address field.

Among Hyperion’s customers included in the Forbes.com list is Kansas City Life Insurance Company, which implemented Hyperion software in 2005 to streamline its financial reporting and close processes. “As insurance products become more complex and integrated, this can complicate financial reporting,” said Rob Fisher, assistant vice president of financial systems and accounting operations at Kansas City Life. “If your data doesn’t easily integrate or can’t be analyzed across the company, you can’t monitor and manage your revenues and costs. In the face of Sarbanes-Oxley and other regulatory requirements, companies like ours have to find ways to remain competitive while still meeting or exceeding our compliance obligations. Being recognized as one of the country’s most trustworthy companies is validation that we’re doing it right.”

“It’s exciting to learn that Hyperion and its customers represent more than a third of the 100 most trustworthy companies in America,” said Godfrey Sullivan, president and CEO of Hyperion. “This honor is especially meaningful to us, as many of our customers rely on Hyperion Solutions to help them trust their numbers and lower the costs and operational impact of regulatory compliance. We’re proud to join so many great companies on this highly selective list.”

Audit Integrity drew its list of 100 from a pool of 8,000 public U.S. companies. To ensure that the list included only companies that are widely held, Audit Integrity excluded any company with a market capitalization of less than $250 million.

For each company, Audit Integrity assigned an Accounting and Governance Risk (AGR) score. The AGR score reflects financial and non-financial factors that help assess the risk of fraud or financial misrepresentation. Hyperion received a current-quarter AGR score of 83. Scores on the Forbes.com list range from 78 to 88.
