Mannatech Global Expansion Reaches Singapore

Initially, the Singapore business will be operated and managed from Mannatech's Australian headquarters with the Singaporean office expected to open sometime in the first half of 2009.

"Given our track record for global expansion success, we are looking forward to entering the Singapore market where we know there is already an interest in Mannatech products," said Wayne Badovinus, president and CEO of Mannatech. "Opening in Singapore is a natural progression for Mannatech since we have had success in numerous Asian markets. Singapore's culture and traditions relative to personal health align well with Mannatech's emphasis on the combination of optimal health and financial wellness."

Singapore is a main island and a series of smaller islands with a total area of 240 square miles. More than 500,000 people (11 percent of the population) are recorded as being active in direct selling. In 2006, the total value of the direct selling market was reported to be $302 million (U.S.).
