Digi International Reports 25.3% Increase in Revenue
for First Fiscal Quarter 2007 Over First Fiscal Quarter 2006

(Minneapolis, MN, January 18, 2007)-Digi International^® Inc. (NASDAQ: DGII) reported revenue of $41.8 million for the first fiscal quarter of 2007 compared with $33.4 million for the first fiscal quarter of 2006, an increase of $8.4 million, or 25.3%. Other financial highlights for the quarter include:

• Revenue increased sequentially from the fourth quarter of fiscal 2006 by 1.9%, despite a traditionally weaker first fiscal quarter.

• Operating income increased by 50% over the first fiscal quarter of 2006.

• Digi met its quarterly revenue and earnings per share guidance.

MaxStream, which Digi acquired in July 2006, contributed $4.6 million in revenue for the quarter. Revenue from embedded products in the first quarter of fiscal 2007 was $16.6 million, an increase of $2.6 million, or 18.5% compared to the first quarter of 2006. Revenue from non-embedded products was $25.2 million in the first quarter of 2007, an increase of $5.8 million, or 30.2% compared to the first quarter of 2006.

Gross profit margin in the first quarter of 2007 was 52.6% compared with 54.5% during the same quarter of fiscal 2006. The decrease in gross profit margin in the first quarter of 2007 compared to the first quarter of 2006 was due to lower sales of mature products with higher gross profit margins, as well as higher manufacturing expenses. Gross profit margin includes the amortization of identifiable intangibles for purchased and core technology, which impacted gross profit margin in the first quarter of 2007 and 2006 by 2.8% and 3.5% respectively.

Total operating expenses in the first quarter of 2007 were $17.7 million, or 42.3% of revenues, compared with $15.3 million, or 45.9% of revenue, in the first quarter of 2006. The increase in operating expenses is attributable to the inclusion of operating expenses pertaining to MaxStream and variable compensation expenses related to the increase in revenue. Operating expenses as a percent of net sales decreased by 3.6 percentage points in the first quarter of 2007 compared to the first quarter of 2006 as Digi continues to focus on controlling expenses while increasing revenue.

Operating income improved to $4.3 million, or 10.3% of net sales, in the first quarter of 2007, compared with $2.9 million, or 8.6% of net sales, in the first quarter of 2006.

Net income was $3.8 million in the first quarter of 2007, or $0.15 per diluted share, compared with $2.2 million in the first quarter of 2006, or $0.09 per diluted share, or an increase of 74.2%. As a result of the extension of the research and development credit for two additional years beyond calendar 2005, a benefit for research and development credits earned during the last three quarters of fiscal 2006 was recorded in the first

quarter of 2007, resulting in an additional tax benefit of $0.5 million, or $0.02 per diluted share.

Digi’s cash and cash equivalents and marketable securities balance at the end of the first quarter of 2007 was $61.5 million, an increase of $2.6 million over the cash and cash equivalents and marketable securities balance at the end of fiscal 2006. Digi’s current ratio is 5.2 to 1, and the Company has no debt other than insignificant amounts of capital lease obligations.

“We started off fiscal 2007 with a good quarter,” said Joe Dunsmore, Digi’s Chief Executive Officer. “We are pleased with our financial results, particularly our continued strong profitability.”

First Fiscal Quarter 2007 Business Highlights:
