Emeryville, CA — (BUSINESS WIRE) — May 27, 2008 — Jamba, Inc. (NASDAQ:JMBA; NASDAQ:JMBAU; NASDAQ:JMBAW) today reported unaudited financial results for the fiscal first quarter ended April 22, 2008. The Company’s financial statements include the results of its wholly owned subsidiary, Jamba Juice Company.

Fiscal first quarter 2008 (1Q08), 16-week period ended April 22, 2008, compared to fiscal first quarter 2007 (1Q07), 16-week period ended May 1, 2007:

• Company-owned comparable store sales⁽¹⁾ of (4.2%), compared to 4.2% in 1Q07. In California, company-owned comparable store sales⁽²⁾ of (5.6%); outside California, company-owned comparable store sales of 0.6%.

• 17 new company-owned stores were opened, compared to 17 new company-owned stores in 1Q07. This brings the total number of company-owned stores to 515 and the total number of system-wide stores (company-owned and franchise-operated stores) to 726.

• Loss from operations of $19.6 million, compared to loss from operations of $8.0 million in 1Q07. Included in the 1Q08 loss is a $4.0 million store impairment expense, compared to $0.1 million in 1Q07.

• Net loss of $6.4 million, compared to net income of $11.9 million in 1Q07. Included in the 1Q08 loss is a gain from derivative liabilities of $5.6 million, compared to a $15.2 million gain in 1Q07.

• Diluted loss per share of ($0.12), compared to diluted earnings per share of $0.20 in 1Q07.

“While our first quarter results did not meet our expectations, I believe that we have the right strategy in place to transform our business to a healthy living company, improve the performance of our existing stores, and increase shareholder value,” said Paul Clayton, Jamba’s ceo. “We’ve further slowed the growth of new stores to shift and intensify our focus on improving the performance of our existing stores. As a result of this new focus, we’ve reorganized our support functions, including a workforce reduction of approximately 53 team members, and engaged in other cost savings measures which we believe will result in a reduction of G&A expenses between $7 - $8 million on an annualized basis. We have also announced the planned closure of 10 stores and proposed termination of leases for seven unopened stores which will also contribute to improved cash flow.”

“In the first quarter we launched our breakfast platform and, while it’s still early and we have limited results, indications appear positive,” Mr. Clayton continued. “We’re seeing an increase in the percentage of sales coming from the morning daypart, which we believe will ultimately translate into increased comparable store sales.”

Footnotes

⁽¹⁾ Comparable store sales are calculated using sales of stores open at least thirteen full fiscal periods.

⁽²⁾ California company-owned stores represent approximately 76% of the revenue in the comparable store sales base.
