FOR IMMEDIATE RELEASE

Liquidmetal^® Technologies Announces Projected Fourth Quarter Revenue

Rancho Santa Margarita, Ca. January 14th, 2008- Liquidmetal^® Technologies, Inc. OTCBB: LQMT) today announced that based upon preliminary review of its 2007  fourth quarter financial performance, the Company expects to report net revenue of approximately  $8.6 million for the fourth quarter ending December 31, 2007, the highest level of quarterly revenue reported to date for the Company.  Projected fourth quarter net revenue represents an increase from $7.1 million in the third quarter of 2007 and the $6.4 million in the fourth quarter of 2006.  Projected net revenue does not include revenue of licensees from the manufacture and sale of Liquidmetal products although it includes royalty and material sales to our licensees.

Larry Buffington, Chief Executive Officer, commented, “The strong revenue growth in the fourth quarter was due in part to increased demand and adoption of our technology and continued momentum building in our strategy to segment our business into respective business categories, whether through our own subsidiary or a licensee, and allowing each business unit to focus and execute their respective strategies. We are pleased with the trend in the business.”

Liquidmetal Technologies will provide additional details of the fourth quarter financials during a regularly scheduled earnings call to be announced later next month. The Company does not intend to announce projected revenue every quarter prior to the filing of its periodic reports with the SEC.
