Digi International Announces First Fiscal Quarter Revenue and Earnings per Share Guidance; Revises Annual 2009 Revenue and Earnings per Share Guidance

First Fiscal Quarter 2009 Results Expected to be Released January 22, 2009

(Minneapolis, MN - Digi International® Inc. (NASDAQ: DGII, http://www.digi.com) expects to report first fiscal quarter 2009 revenue in a range of $41.0 million to $41.6 million compared to $44.6 million in the first fiscal quarter of 2008, or a decrease of approximately 7% to 8%. Digi previously provided guidance of approximately $47.5 million in revenue for the first fiscal quarter of 2009. The decrease in revenue is a result of lower than anticipated revenue across all regions and product lines attributable to rapidly deteriorating demand conditions during the last half of the first fiscal quarter of 2009. Digi anticipates first fiscal quarter 2009 earnings per diluted share in a range of $0.02 to $0.04, which includes a $0.01 tax benefit due to the extension in the quarter of the income tax credit for increased research and development for the last three quarters of fiscal 2008.

Digi now anticipates fiscal 2009 revenue in a range of $170 million to $200 million, compared to previous guidance of $200 million to $220 million. Earnings per diluted share are expected to be in a range of $0.19 to $0.47, compared to previous guidance of $0.47 to $0.65.

Digi expects to continue repurchasing its stock under its previously announced stock repurchase program.
