Digi International Reports 21.4% Increase in Revenue for
Third Fiscal Quarter 2007 Over Third Fiscal Quarter 2006

(Minneapolis, MN, July 23, 2007)-Digi International^® Inc. (NASDAQ: DGII) reported revenue of $ $43.5 million for the third quarter of 2007 compared with $35.9 million for the third quarter of 2006, an increase of $7.6 million, or 21.4%. Other financial highlights for the quarter include:

• Operating income and net income increased by 35.9% and 103.0%, respectively, over the third quarter of 2006.

• Earnings per diluted share increased by 86% over the third quarter of 2006, including discrete tax benefits recorded in the third quarters of fiscal 2007 and 2006.

Revenue from embedded products in the third quarter of 2007 was $18.8 million, an increase of $5.1 million, or 37.2%, compared to the third quarter of 2006. Revenue from non-embedded products was $24.7 million in the third quarter of 2007, an increase of $2.6 million, or 11.6%, compared to the third quarter of 2006. MaxStream-branded product revenue was $5.4 million for the third quarter of 2007. MaxStream was acquired on July 27, 2006.

Gross profit margin in the third quarter of 2007 was 52.8% compared with 54.3% during the same quarter of fiscal 2006. The decrease in gross profit margin was due to lower sales of higher gross profit margin mature products and other product mix changes within both the embedded and non-embedded product categories. Gross profit margin includes the amortization of identifiable intangibles for purchased and core technology, shown separately on our Condensed Consolidated Statements of Operations.

Operating expenses as a percent of net sales decreased by 2.7 percentage points in the third quarter of 2007 compared with the third quarter of 2006 as Digi continues to focus on controlling expenses while increasing revenue. Total operating expenses in the third quarter of 2007 were $17.9 million, or 41.1% of revenue, compared with $15.7 million, or 43.8% of revenue, in the third 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 income increased by 35.9% in the third quarter of 2007 compared to the same quarter of 2006. Operating income was $5.1 million, or 11.7% of net sales, in the

third quarter of 2007, compared with $3.8 million, or 10.5% of net sales, in the third quarter of 2006.

Digi recorded a discrete tax benefit of $2.9 million in the third quarter of 2007 equating to $0.11 per diluted share pertaining to the closing of a domestic tax return and the settlement of a foreign tax audit. As a result of the aforementioned events taking place in the third quarter of 2007, Digi reversed previously established tax reserves associated with these items. During the third quarter of 2006 Digi recorded a tax benefit of $0.6 million equating to $0.02 per diluted share pertaining to the recovery of discrete tax benefits in the quarter.

Net income was $6.8 million in the third quarter of 2007 compared to $3.3 million in the third quarter of 2006, an increase of 103.0%. Earnings per diluted share were $0.26 in the third quarter of 2007 compared to $0.14 in the third quarter of 2006, an increase of 86%.

For the nine months ended June 30, 2007, Digi reported revenue of $128.2 million compared to revenue of $103.6 million for the nine months ended June 30, 2006, or an increase of 23.7%. For the nine months ended June 30, 2007, Digi reported net income of $14.2 million compared to $8.1 million for the nine months ended June 30, 2006, an increase of 75.3%. Earnings per diluted share were $0.55 for the first nine months of 2007 compared to $0.34 for the comparable period in 2006, an increase of 59%.

Digi’s cash and cash equivalents and marketable securities balance at the end of the third quarter of 2007 was $78.0 million, an increase of $19.1 million over the cash and cash equivalents and marketable securities balance at the end of fiscal 2006. Digi’s current ratio is 5.7 to 1, and the Company has no debt other than insignificant amounts of capital lease obligations.

“This was another strong quarter for Digi,” said Joe Dunsmore, Digi’s Chief Executive Officer. “In particular, our operating income improvement of 35.9% year over year is indicative of our positive operating momentum.”
