Digi International Reports Fiscal Second Quarter 2003 Results
Exceeds earnings per share estimates for the quarter and
provides improved earnings per share guidance for the year

(Minneapolis, MN, April 16, 2003) — Digi International® Inc. (NASDAQ: DGII) reported revenues of $25.5 million for the fiscal second quarter of 2003 compared to $25.5 million in the prior quarter and $25.2 million in the fiscal second quarter of 2002. Revenue for the quarter met the high end of management’s previously disclosed guidance of $24.5 — $25.5 million.

Digi reported net income of $2.5 million for the fiscal second quarter of 2003, or $0.12 per diluted share, compared to a net loss of $7.3 million, or $0.39 per diluted share, in the fiscal second quarter of 2002. These results compare to a net loss of $42.8 million in the fiscal first quarter of 2003, or $1.94 per diluted share. Digi adopted Statement of Financial Accounting Standards No. 142 “Goodwill and Other Intangible Assets” (SFAS 142) in the fiscal first quarter of 2003, and recorded a non-cash goodwill impairment charge of $43.9 million as a change in an accounting principle. Income before the cumulative effect of accounting change was $1.1 million, or $0.05 per diluted share in the fiscal first quarter of 2003. Earnings per share for the quarter exceeded management’s previously disclosed guidance of $0.02 — $0.04.

During the fiscal second quarter of 2003 Digi recognized the beneficial impact of reversing an income tax valuation reserve related to its German net operating loss carryforwards. Management concluded that the previously recorded valuation allowance should be reversed based upon current and anticipated taxable income generated by its German operations. The impact of this decision was a tax benefit of $1.4 million, or $0.07 per diluted share in the second quarter.

Revenue from Digi Connectware products was $17.3 million for the fiscal second quarter. Device Networking products, which include NetSilicon and the Device Server product lines, contributed $8.2 million in the second quarter.

Gross margins in the fiscal second quarter of 2003 were 59.6%, compared to 60.1% in the previous quarter and 52.3% in the fiscal second quarter of 2002. The increase in 2003 gross margins is primarily a result of replacing lower margin LAN products with higher margin embedded networking connectivity products.

Total operating expenses in the fiscal second quarter of 2003 were $13.7 million, compared to $13.9 million in the previous quarter.

“We are very pleased to achieve revenue results at the high-end of our guidance and to exceed our earnings expectations,” said Joe Dunsmore, Chairman, President and CEO of Digi. “Our execution continues to improve in the face of the continued challenging market conditions.”

Digi’s cash and marketable securities balance at the end of the quarter was $56.5 million, an increase of $2.1 million from the end of the prior quarter. Days sales outstanding (DSO) was at 34 days, an increase of one day from the previous quarter. Digi’s cash per share, defined as cash and marketable securities divided by March 31, 2003 shares outstanding of 21,235,686, was $2.66.

REVENUE AND EARNINGS GUIDANCE:

Digi expects fiscal third quarter 2003 revenue to be in the range of $24.5 — $25.5 million and anticipates earnings per diluted share to be in the range of $.03 — $.05. For the full fiscal year, the revenue guidance remains the same as forecasted in the range of $101 — $103 million. Digi is increasing its guidance for earnings per diluted share, excluding the impact of adoption of SFAS 142, to a range of $0.23 — $0.27, from the previously forecasted range of $0.13 — $0.17. Including the impact of adoption of SFAS 142, diluted loss per share is forecasted to be in a range of $1.76 — $1.79, a reduction from the forecasted loss per diluted share of $1.82 - $1.86.
