THE WOODLANDS, Texas, Aug. 30, 2023 (GLOBE NEWSWIRE) -- Graf Acquisition Corp. IV (NYSE:GFOR, GFOR-UN, GFOR-WT))) (the "Company" or "Graf"), announced today that it intends to adjourn, without conducting any business, the special meeting of its stockholders to be held to approve, among other things, the previously announced business combination (the "Business Combination") with NKGen Biotech, Inc. ("NKGen" and such special meeting, the "Special Meeting"), which is scheduled to occur at 10:00 a.m., Eastern time, on August 30, 2023, and to reconvene the Special Meeting at 10:30 a.m., Eastern time, on September 8, 2023. The Special Meeting will still be held virtually at https://www.cstproxy.com/grafiv/sm2023.

The Company has received overwhelming support for the approval of the Business Combination and has received enough votes to date via proxy to approve each of the proposals to be presented at the Special Meeting. However, the Company has decided to adjourn the Special Meeting in order to provide additional time to continue its efforts to obtain additional financing, which may be in the form of equity, debt, grants or other equity-linked securities or derivatives, needed to satisfy the $50 million minimum cash condition under the agreement and plan of merger entered into in connection with the Business Combination, which may be waived by NKGen, in its sole discretion.

In connection with the adjournment of the Special Meeting, the Company is reopening and extending the deadline for its stockholders to exercise their right to redeem their shares of common stock for their pro rata portion of the funds available in the Company's trust account, or to withdraw any previously delivered demand for redemption, to 5:00 p.m., Eastern time, on September 6, 2023 (two business days before the adjourned Special Meeting). If a stockholder has previously submitted a request to redeem its shares of common stock in connection with the Special Meeting and would like to reverse such request, such stockholder may contact the Company's transfer agent, Continental Stock Transfer & Trust Company, at SPACredemptions@continentalstock.com.

Stockholders of record as of August 7, 2023 are entitled to vote at the Special Meeting. Stockholders who have not yet done so are encouraged to vote as soon as possible. Stockholders who have previously submitted their proxies or otherwise voted and who do not want to change their vote need not to take any further action. If any stockholders have questions or need assistance in connection with the Special Meeting, please contact the Company's proxy solicitor, Morrow Sodali LLC, by calling (800) 662-5200, or banks and brokers can call collect at (203) 658-9400, or by emailing GFOR.info@morrowsodali.com.
