Mannatech Reports Fourth Quarter and Full Year 2007

Sales and earnings decline; additional accrual made for litigation

Coppell, TX, March 14, 2008 – Mannatech, Incorporated (NASDAQ – MTEX) today reported a fourth quarter 2007 loss of $3.6 million or $0.13 cents per diluted share, which included an accrual of $4.7 million for litigation-related expenses. This compares to $0.30 cents earnings per diluted share and $8.2 million of net income for the fourth quarter of 2006. The company reported a pretax loss of $4.7 million compared to $12.2 million for the fourth quarter of 2006.

Fourth quarter net sales for 2007 were $99.9 million, a decrease of 6.5%, compared to $106.8 million in the fourth quarter of 2006. The sales decline resulted from a 20% decrease in North America sales compared to the fourth quarter of 2006. This was partially offset by a 27% increase in sales from international markets, primarily in Asia, in the fourth quarter of 2007 compared to the fourth quarter of 2006.

Terry Persinger, President and CEO commented, “Our U.S. market continues to experience softer sales and recruiting impacted by ongoing litigation. The company is continuing discussions with the Texas Attorney General’s staff toward a satisfactory resolution. In the meantime, we continue to invest in vital areas to restore sales and recruiting momentum. The higher fourth quarter expense levels reflected our strategy in the short-term to continue funding for the new research, products, and sales programs that will grow our business.”

Mr. Persinger continued, “We are looking for renewed momentum and improved profitability in the latter part of this year, resulting from the dual emphasis on global business development and cost management. A new sales platform and initiatives will kick off at MannaFest, our annual convention at the end of this month. At the same time, we look to enter new markets starting with the opening of South Africa in the second quarter.”

Total independent Associate and Member count based on a 12-month trailing period increased to 575,000 for the fourth quarter of 2007 as compared to 544,000 for the fourth quarter of 2006. The 5.7% growth resulted from higher retention of continuing independent Associates and Members which were up 43,000, a 12.6% increase compared to the same period last year. This increase was partially offset by a 5.9% decline in new independent Associates and Members on a 12-month trailing basis.

Full year 2007 net sales reached $412.7 million, up 0.1% from 2006. Net income for the full year 2007 was $6.6 million, compared to the full year 2006 net income of $32.4 million. Diluted earnings per share were $0.25 cents compared to $1.19 for the full year 2006.
