Diedrich Coffee Reports First Quarter Results

Irvine, California, November 7, 2005–Diedrich Coffee, Inc. (Nasdaq: DDRX) today announced operating results for its first fiscal quarter of 2006, which ended September 21, 2005. For the quarter, the Company reported a net loss of $1,552,000, or $0.29 per share, compared to a loss of $468,000, or $0.09 per share, for the first quarter of the prior fiscal year.

The prior year quarter included $556,000 or $0.11 per share of earnings from the discontinued operations of the Gloria Jean’s international franchise operations that we sold in February 2005. The loss in this year’s first quarter from continuing operations of $1,552,000 or $0.29 per share compares to a loss of $1,024,000 or $0.20 per share from continuing operations in last year’s quarter.

Roger Laverty, Diedrich Coffee’s Chief Executive Officer, stated “The seasonality of the Company’s business typically produces first quarter losses. The increase in loss from continuing operations in this year’s quarter was due to additional audit and tax fees related to the 2005 fiscal year, expense related to the adoption of new accounting rules for stock options and costs associated with a lease buyout that allowed us to close a very unprofitable coffeehouse.”

Laverty added “Obviously loss of the earnings stream from the international Gloria Jean’s franchise operations had a huge impact on the quarterly results. We believe the sale of that operation captured maximum value for our shareholders and it left us with the resources to aggressively grow the business in the United States. Domestic coffeehouse openings do not immediately produce earnings, but we believe that the growth we are beginning to achieve will ultimately replace the international earnings contribution.”

Revenue

Total revenue for the twelve weeks ended September 21, 2005, was $12,180,000, an increase of $966,000 (8.6%) compared with revenue of $11,214,000 for the prior year period. Segment increases were $759,000 (10.6%) in retail sales, $343,000 (10.6%) in wholesale sales, and a decline of $136,000 (15.9%) in franchise revenue.

The increase in retail sales for the first fiscal quarter versus the prior year quarter was the result of a 3.8% increase in same company-operated store sales and a net increase of three stores since the beginning of the prior year quarter (nine stores were opened, four were closed and a net of

two were transferred to franchisees). E-commerce retail sales also increased by $47,000 above sales of the prior year quarter.

System-wide comparable store sales at Diedrich Coffee brand coffeehouses open for at least one year increased 1.0% for the quarter, as compared with the prior year, while comparable store sales at the Company’s Coffee People locations increased 6.3% during this same period. System-wide comparable store sales at Gloria Jean’s units declined 3.2% during the first fiscal quarter compared to the prior year quarter.

The increase in wholesale sales was due to a $382,000 increase in sales to third party customers partially offset by a decrease of $38,000 in sales of roasted coffee to franchisees.

Franchise revenue decreased primarily due to the net effect of a $72,000 decrease in royalties, a $28,000 increase in roasting and new store fees and an accounting reclassification of $91,000 of coordination fees to general and administrative expense. Since the beginning of fiscal 2005, the domestic franchise units increased by a net of two units.

Costs and Expenses

Cost of sales and related occupancy costs increased from 53.2% of retail and wholesale sales in the prior year quarter to 56.3% in the current quarter. The increased costs were almost entirely in the wholesale segment. Planned cost reductions and price adjustments are expected to improve gross margins for the remainder of the fiscal year.

Operating expenses remained relatively stable, increasing from 37.8% of retail and wholesale sales in the first quarter of last year to 38.0% in the first quarter of the current year.

General and administrative expenses increased 11.6% from $2,566,000 in the prior year quarter to $2,863,000 in the current year quarter. Primary factors in the increase were audit and tax fees expensed in the first quarter of fiscal 2006 that related to fiscal 2005 year. Also, adopting the new accounting pronouncement requiring expensing employee stock options increased expense by $85,000.
