In its annual report on Form 10-KSB for the year ended December 31, 2007, Circuit Research Labs, Inc. (the “Company”) expects to report net sales of approximately $12.9 million.  This reflects an increase of 2% from net sales of $12.6 million for the year ended December 31, 2006. 

The Company anticipates its gross profit for the year ended December 31, 2007 to be approximately 56% compared to 54% for 2006, or $7.2 million in 2007 as compared to $6.9 million in 2006.  The overall increase in the gross profit as a percentage of net revenue is primarily attributed to our ability to increase production runs and reduce costs associated with setup and labor.
