Press Release: Illumina to Close Connecticut Operations, Take Related Charge

Illumina to Close Connecticut Operations, Take Related Charge SAN DIEGO -- Illumina, Inc. announced today that it intends to consolidate its operations in Wallingford, Connecticut into its facilities in San Diego, California. The Wallingford site was originally established in connection with the acquisition of CyVera Corporation and has supported the development and manufacture of the BeadXpress system which was launched in March of 2007. The consolidation is expected to be completed over the course of 2007. Upon completion, all manufacturing and development activities related to the BeadXpress system will continue in San Diego. As a result of the transition, Illumina will incur incremental charges of approximately $2 million. Combined with the expected efficiency gains, these charges are not expected to materially impact the Company's financial performance for 2007. "With the completion of our acquisition of Solexa, we took the opportunity to evaluate all of our operations. We determined that consolidating the Wallingford operations into San Diego will provide us with efficiencies from both the manufacturing and product development perspective," said Jay Flatley, President and Chief Executive Officer. "We now will concentrate research and development and manufacturing activities in our San Diego and Hayward, California and Little Chesterford, United Kingdom facilities, all of which are expected to continue expanding as we see increasing demand for our products and services."
