Graf Acquisition Corp. IV Announces Adjournment of Special Meeting to Approve Business Combination with NKGen Biotech, Inc. to September 25, 2023

THE WOODLANDS, Texas, Sept. 22, 2023 /PRNewswire/ -- Graf Acquisition Corp. IV (NYSE:GFOR, GFOR.U, GFOR WS))) (the "Company" or "Graf"), announced today that on September 20, 2023, it adjourned, 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"). The Special Meeting will be reconvened at 4:00 p.m., Eastern time, on September 25, 2023. The Special Meeting will still be held virtually at https://www.cstproxy.com/grafiv/sm2023. The Company has decided to adjourn the Special Meeting once again 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, in connection with the Business Combination.

The Company also filed a supplement (the "Supplement") to its definitive proxy statement/prospectus relating to the Special Meeting (the "Definitive Proxy Statement/Prospectus") that was initially filed on August 14, 2023, with the Securities and Exchange Commission (the "SEC") today to disclose some recent developments, including that NKGen waived the $50 million minimum cash condition under the agreement and plan of merger entered into in connection with the Business Combination, as well as to add one new proposal to be voted on at the Special Meeting. As previously announced, the Company has received enough votes to date via proxy to approve each of the proposals included in the original Definitive Proxy Statement/Prospectus; however, the previously submitted proxy cards and voting instruction forms will not be voted on the one new proposal. As a result, even if you have already voted your shares, we strongly encourage you to read the Supplement and vote on the one new proposal. To vote on the one new proposal, you must vote the proxy card or voting information form distributed along with the Supplement. The proxy card or voting instruction form distributed with the Definitive Proxy Statement/Prospectus remains valid with respect to the other proposals presented at the Special Meeting and stockholders who have already returned their proxy card or provided voting instructions do not need to take any action unless they want to change or revoke their voting instructions on the other proposals.

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 [email protected].
