Opexa Therapeutics, Inc. Urges Shareholders to Vote FOR the Merger with Acer Therapeutics; The Merger will Not Go Forward Unless ALL Proposals are Approved

THE WOODLANDS, TX / ACCESSWIRE / September 13, 2017 / Opexa Therapeutics, Inc. (NASDAQ: OPXA) reminds and urges its shareholders to vote for the proposed merger with Acer Therapeutics, Inc. before the upcoming special meeting of Opexa shareholders, which will be held on Tuesday, September 19, 2017. Shareholders who have not already done are strongly encouraged to vote their shares in favor of the merger and all related proposals.

Opexa reminds shareholders that Institutional Shareholder Services Inc. (ISS) and Glass, Lewis & Co., LLC (Glass Lewis) have both recommended that Opexa shareholders vote "FOR" the proposed merger with Acer Therapeutics Inc. and the related proposals in the Company's proxy statement/prospectus/information statement for the special meeting.

Your vote is important, no matter how many or how few shares you may own. Failure to vote or an abstention from voting will have the same effect as a vote "AGAINST" the name change and reverse stock split proposals. All shareholders are asked to vote "FOR" all proposals as soon as possible as the merger will not go forward unless all proposals are approved.

If you are an Opexa shareholder and you have questions or require assistance in submitting your proxy or voting your shares, or wish to change a vote previously cast, please contact Opexa's proxy solicitor:
