EMCORE Receives Notification of Deficiency From NASDAQ Due to Delay in Filing Form 10-K

ALBUQUERQUE, NM--(Marketwire - January 5, 2011) - EMCORE Corporation (NASDAQ: EMKR), a leading provider of compound semiconductor-based components, subsystems and systems for the fiber optics and solar power markets, today announced that on December 30, 2010, it received a letter from the NASDAQ Stock Market indicating that the Company was not in compliance with the continued listing requirements under NASDAQ Listing Rule 5250^©(1). The NASDAQ letter, which the Company expected, was issued in accordance with standard NASDAQ procedures because the Company did not timely file its Annual Report on Form 10-K for the fiscal year ended September 30, 2010 with the Securities and Exchange Commission.

As previously reported by the Company on December 30, 2010, the filing of the 2010 Form 10-K has been delayed because the Company's prior auditor, Deloitte & Touche LLP, the independent auditing firm that conducted the audit of the Company's financial statements for the fiscal years ended September 30, 2008 and 2009, has not completed their procedures to re-issue their opinion with respect to the Company's financial statements for those fiscal years. Deloitte is specifically reviewing their audit procedures performed on the Company's goodwill and intangible assets accounts. The Company intends to file the 2010 Form 10-K as promptly as practicable once Deloitte is able to re-issue its opinion with respect to the prior fiscal years.

The Company is required to submit a plan to regain compliance with NASDAQ's requirements for continued listing and the plan must be submitted no later than February 28, 2011.
