Arcturus Therapeutics Ltd. (the “Company”) is unable to timely file its Annual Report on Form 20-F for the year ended December 31, 2017 (the “2017 Form 20-F”) in a timely manner without unreasonable effort and expense as a result of the completion of a merger transaction on November 15, 2017 with Arcturus Therapeutics, Inc. From an accounting perspective, Arcturus Therapeutics, Inc. was deemed the accounting acquirer in the transaction, and the Company was the deemed the accounting acquiree. Accordingly, the Company’s financial statements will reflect Arcturus Therapeutics, Inc.’s financial statements up to November 15, 2017, and the combined financial statements for the period subsequent to November 15, 2017. In light of the complexities involved in this transaction, the Company requires additional time to complete its consolidated financial statements for the fiscal year ended December 31, 2017.


The Company anticipates that the 2017 Form 20-F will be filed on or before the fifteenth calendar day following the prescribed due date for the 2017 Form 20-F.
