Thomas Group, Inc. (NasdaqCM:TGIS), a leading operational consulting firm, today announced its addition to the Russell Microcap Index effective June 30, 2006. The Russell Microcap Index measures performance of the microcap segment, representing less than 3% of the U.S. equity market, and includes the smallest 1,000 securities in the small-cap Russell 2000(R) Index, plus the next 1,000 securities. "Inclusion in the Russell Microcap Index is yet another indicator of our growth over the past 12 months," said Jim Taylor, CEO of Thomas Group. "Our year-over-year comparisons are favorable in revenue, profits, debt levels and almost any other metric an investor might choose to measure, not the least of which is a 68% year-over-year increase in revenue for the first quarter. We remain confident in our ability to increase shareholder value, as evidenced by the increase in our annual dividend announced two weeks ago. We anticipate our visibility to investors and institutions will increase as a result of inclusion in the Russell Index." Thomas Group, Inc.
