EMCORE Corporation Announces Preliminary Financial results for the Fourth Fiscal Quarter Ended September 30, 2020

Alhambra, CA, October 19, 2020 – EMCORE Corporation (Nasdaq: EMKR), a leading provider of advanced mixed-signal products that serve the aerospace & defense and broadband communications markets, announced preliminary financial results for its fourth fiscal quarter ended September 30, 2020.

EMCORE expects its revenue for the quarter to be approximately $33.5 million compared to its previous revenue guidance range of $29 million to $31 million.

Jeff Rittichier, EMCORE’s President and CEO commented, “MSOs ramped up their investments to break network bottlenecks, driving greater-than-anticipated growth in our Broadband business. L-EML transmitter shipments were particularly strong, demonstrating the unique value of this product. Revenue for QMEMS and Defense Optoelectronic products within our Aerospace & Defense segment also exceeded our expectations. Looking ahead, we see the robust order book for our cable TV products extending through the March ‘21 quarter.”

These preliminary, unaudited results are based on the most current information available to management following its initial review of operations for the quarter ended September 30, 2020 and remain subject to completion of EMCORE’s customary closing procedures, including external auditor review. EMCORE expects to provide final financial results for its fourth fiscal quarter during the week of November 30, 2020.
