SPECIALTY PHOSPHATE FOOD INGREDIENTS

CRANBURY, New Jersey – (February 3, 2011) – Innophos Holdings, Inc. (NASDAQ: “IPHS”), a  leading North American specialty phosphates producer, today announced important capacity expansions targeted at further strengthening its industry leading position in the supply of specialty phosphate ingredients to the food and beverage markets.

Þ  At its Port Maitland, Ontario facility, the Company announced the completion of an expansion for the production of potassium phosphates. These specialty products provide unique functionality for the meat and dairy industries and also have applications in industrial markets including water treatment and industrial cleaners.

Þ  At its Chicago Heights, IL facility, the Company announced plans for a 25% increase in tri-calcium phosphate capacity. Tri-calcium phosphate is used throughout the food industry and has seen significant increase in demand particularly in the beverage and dairy segments.  This expansion uses new process technology which achieves a significant improvement in throughput and a broader product range by optimizing existing production lines at Chicago Heights. The expansion is expected to be completed by mid year 2011.

Þ  The company also confirmed that its previously announced expansion of CAL-RISE^® capacity at its Nashville, TN facility is on schedule to be completed in July of this year.  The investment will also provide a 50% increase in the capacity for mono-calcium products V-90 and Regent 12XX.

Golowski, Vice President of the Specialty Phosphates Business. ”In addition to providing a significant capacity increase, these upgrades achieve important extensions to our product range to better meet the needs of our customers.  Our enhanced product portfolio will further strengthen Innophos’ industry-leading capability in enabling food and beverage customers to effectively respond to consumer demand for lower sodium products and for calcium fortification.”
