Share repurchase program

Waters has announced that at the end of February 2009, its Board of Directors authorized the company to repurchase up to $500 million of its outstanding common shares over the next 24 months.

A previous $500 million share repurchase program which had been authorized in February 2007 has expired, but was described by the company as “substantially completed”.

Purchases will be made through open market transactions, subject to market conditions and trading restrictions.
