If a business combination is not completed by July 2, 2019, this contribution will increase funds available in Jensyn Acquisition’s trust account for the conversion of shares from approximately $11.00 per share on January 3, 2019 to approximately $11.30 per share at July 2, 2019.

The January 2, 2019 special meeting of stockholders is being held to seek an extension of the date by which the Company must complete its initial business combination from January 3, 2019 to July 2, 2019. If the extension is not approved, no additional deposit will be made to the trust account.

The record date for the January 2, 2019 special meeting of stockholders is December 10, 2018. Stockholders who acquired their shares after December 10, 2018 will not be entitled to vote at the January 2, 2019 special meeting of stockholders or exercise conversion rights with respect to those shares in connection with the vote to extend the date by which the Company must complete its initial business combination. These stockholders, will, however, have the right to receive a pro rata share of the funds in the trust account if the extension is not approved and the Company is liquidated and dissolved, and will have the right to vote and exercise conversion rights with respect to their shares in connection with a proposed business combination provided they hold shares as of the business combination meeting record date, which has not yet been set.
