SAN DIEGO — Illumina, Inc. (NASDAQ:ILMN), a leading developer, manufacturer, and marketer of life science tools and integrated systems for the analysis of genetic variation and function, today announced that independent proxy advisory firm Glass, Lewis & Co., LLC (“Glass Lewis”) has recommended that Illumina’s stockholders vote for the election of Illumina’s highly qualified nominees at its 2012 Annual Meeting of Stockholders by completing the WHITE proxy card.

“We are very pleased that all three of the leading proxy advisors – Institutional Shareholder Services, Glass Lewis and Egan-Jones – have now recommended that their clients support the re-election of Illumina’s slate of directors and vote against all of Roche’s proposals at Illumina’s upcoming Annual Meeting,” said Jay T. Flatley, President and CEO of Illumina. “The simple fact remains that Roche’s unsolicited offer clearly undervalues Illumina and that our highly qualified and experienced directors are best positioned to create value for Illumina’s stockholders. We are confident that Illumina’s stockholders will reject Roche’s hostile and opportunistic efforts to acquire Illumina at a grossly inadequate price.”
