Digi International Reports 24.7% Increase in Revenue for
Second Fiscal Quarter 2007 Over Second Fiscal Quarter 2006

Revenue and Earnings Per Share Guidance Raised for Remainder of Fiscal 2007

(Minneapolis, MN, April 25, 2007) - Digi International^® Inc. (NASDAQ: DGII) reported revenue of $42.9 million for the second quarter of 2007 compared with $34.4 million for the second quarter of 2006, an increase of $8.5 million, or 24.7%. Other financial highlights for the quarter include:

• Operating income and net income increased by 46.8% and 40.1%, respectively, over the second quarter of 2006.

• Revenue growth of 24.7% consisted of organic revenue growth of 10% and revenue growth from MaxStream, acquired in July 2006, of 14.7%.

• Digi met its quarterly revenue and earnings per share guidance. The business outlook for the year has improved, and Digi has increased its revenue and earnings per share guidance for the remainder of fiscal 2007.

Revenue from embedded products in the second quarter of 2007 was $18.4 million, an increase of $5.3 million, or 40.7%, compared to the second quarter of 2006. Revenue from non-embedded products was $24.5 million in the second quarter of 2007, an increase of $3.2 million, or 14.8%, compared to the second quarter of 2006. MaxStream contributed $5.0 million in revenue for the second quarter of 2007.

Gross profit margin in the second quarter of 2007 was 52.5% compared with 53.3% 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 2.5 percentage points in the second quarter of 2007 compared with the second quarter of 2006 as Digi continues to focus on controlling expenses while increasing revenue. Total operating expenses in the second quarter of 2007 were $17.8 million, or 41.5% of revenue, compared with $15.1 million, or 44.0% of revenue, in the second 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 46.8% in the second quarter of 2007 compared to the same quarter of 2006. Operating income was $4.7 million, or 11.0% of net sales, in the second quarter of 2007, compared with $3.2 million, or 9.3% of net sales, in the second quarter of 2006.

Net income was $3.6 million in the second quarter of 2007, or $0.14 per diluted share, compared with $2.6 million in the second quarter of 2006, or $0.11 per diluted share, or an increase of 40.1%.

For the six months ended March 31, 2007, Digi reported revenue of $84.7 million compared to revenue of $67.8 million for the six months ended March 31, 2006, or an increase of 25.0%. For the six months ended March 31, 2007, Digi reported net income of $7.4 million, or $0.28 per diluted share, compared to net income for the six months ended March 31, 2006, of $4.8 million, or $0.20 per diluted share, an increase of 56%.

Digi’s cash and cash equivalents and marketable securities balance at the end of the second quarter of 2007 was $69.9 million, an increase of $11.0 million over the cash and cash equivalents and marketable securities balance at the end of fiscal 2006. Digi’s current ratio is 5.5 to 1, and the Company has no debt other than insignificant amounts of capital lease obligations.

“I am pleased with our financial results, particularly our strong profitability, for the first half of 2007,” said Joe Dunsmore, Digi’s Chief Executive Officer.
