If the subject report could not be filed without unreasonable effort or expense and the registrant seeks relief pursuant to Rule 12b-25(b), the following should be completed. (Check box if appropriate)

PART III – NARRATIVE

State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-CEN, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.

As previously disclosed in the Current Report on Form 8-K filed by EMCORE Corporation (“EMCORE”) with the Securities and Exchange Commission on August 9, 2022, EMCORE purchased the assets related to the inertial navigation segment (the “Business”) from KVH Industries (“KVH”) on that date pursuant to the terms of the Asset Purchase Agreement (the “Purchase Agreement”) dated as of August 9, 2022 (the “Effective Date”).

EMCORE and KVH also entered into a Transition Services Agreement (the “TSA”) dated August 9, 2022 which obligated KVH to provide EMCORE transition services, which services include but are not limited to providing EMCORE financial information as to the performance of the Business for the period from the Effective Date until the end of EMCORE’s fiscal year (September 30, 2022) (the “Financial Information”).

KVH did not provide the Financial Information to EMCORE on a timely basis in order for EMCORE to complete its internal financial statement close process, including the accounting for the preliminary purchase price allocation associated with the Business, for the three-month and twelve-month period ended September 30, 2022. As a result, EMCORE was unable to compile in a timely manner the consolidated financial information required to prepare its Annual Report on Form 10-K for the year-ended September 30, 2022, within the prescribed time period.

EMCORE anticipates that it will file its Annual Report on Form 10-K for the year ended September 30, 2022 as soon as possible within the filing extension period.
