Agilysys Provides New Guidance for Fiscal 2011 Results

CLEVELAND—May 16, 2011—Agilysys, Inc. (Nasdaq: AGYS), a leading provider of innovative IT solutions, today announced that it is lowering its guidance for the fiscal year ended March 31, 2011. Projected results are unaudited and subject to the ongoing audit closing process.

The Company now expects to report consolidated revenue of approximately $676 million and adjusted EBITDA, excluding asset impairment and restructuring charges, ranging between a loss of $3 million and break-even for the fiscal year ended March 31, 2011. Cash on hand was approximately $74 million as of March 31, 2011. The Company also expects to record a non-cash charge ranging between $34 million and $42 million for impairment of acquisition-related goodwill and intangible assets in its Technology Solutions Group in fiscal 2011.

“Revenues for the Technology Solutions Group (TSG) and Retail Solutions Group (RSG) are expected to be below the internal estimates used to provide the previous guidance,” said Martin Ellis, president and chief executive officer. “Strong execution in our Hospitality Solutions Group (HSG) is expected to result in revenue above the internal estimates used to provide the previous guidance.”

The Company will provide more detail on its performance when it announces its fiscal 2011 fourth-quarter and full-year results on or before June 14, 2011.
