Leading Proxy Advisory Firms ISS and Glass Lewis Demonstrate Strong Support for Zevra’s Transformation Strategy

Glass Lewis Recommends a Vote “FOR” Zevra’s Three Nominees

Both ISS and Glass Lewis Recommend Shareholders DO NOT Vote “FOR” Any of the Mangless Nominees

Zevra Urges Shareholders to Vote on the WHITE Proxy Card

CELEBRATION, Fla., April 17, 2023 (GLOBE NEWSWIRE) -- Zevra Therapeutics, Inc. (NasdaqGS: ZVRA) (“Zevra” or the “Company” and formerly KemPharm, Inc.), a rare disease therapeutics company, today announced that leading proxy advisory firms Institutional Shareholder Services (“ISS”) and Glass Lewis & Co. (“Glass Lewis”) have voiced their support for Zevra’s nominees and strategy and found that Mangless’ arguments and nominees were not compelling.

The Company urges its shareholder to vote on the WHITE proxy card “FOR” all three nominees - Richard W. Pascoe, David S. Tierney, M.D., and Christopher M. Posner. Votes must be cast during or prior to the Company’s upcoming Annual Meeting of Shareholders (“Annual Meeting”), which is scheduled for April 25, 2023.

In making its recommendation, Glass Lewis stated in its April 7, 2023, report¹:

• “when considering the promulgated alternative to maintenance of the status quo, we do not believe the Dissident has presented investors with a sufficiently persuasive case at this time”
• “we are ultimately inclined to share the board's view, noting, in particular, that Mr. Mangless' materials to date have been somewhat thin on detail, have failed to grapple more directly with Dr. Mickle's opposition to both the current campaign and central components of the dissenting thesis and have not presented what we consider to be compelling plans or persuasive arguments in favor of the Dissident nominees”
• In making its recommendation for the re-election of all of Zevra’s nominees, “[I]nvestors would ultimately be better served supporting the incumbent Zevra nominees at this time”
• In reference to Mangless’ director nominees, “[T]he Dissident has ultimately advanced a slate which appears to lack decisively strong industry and public company bona fides, which, in our view, raises meaningful questions around the appeal of supporting the Dissident candidates at this time”

In making its recommendation, ISS stated in its April 13, 2023, report¹:

• “In this contest, the dissident's terse arguments laid out in his proxy statement have not risen to the level of a successful case for immediate change at the company”
• “the dissident has failed to make a compelling case for change at the company”
• “Since the dissident has not made a compelling case for change, direct support for the dissident nominees is not warranted under our analytic framework”
• “Votes FOR the remaining director nominee, CEO Richard Pascoe, are warranted”

Commenting on the ISS and Glass Lewis recommendations, Zevra issued the following statement:

We are pleased that ISS and Glass Lewis are supportive of our transformation strategy and believe in our ambitious vision led by our CEO Richard Pascoe. Furthermore, we commend Glass Lewis’ recommendation that shareholders vote “FOR” all of our stated proposals, including the election of our highly qualified director nominees – Richard W. Pascoe, David S. Tierney, M.D., and Christopher A. Posner and not support any of the Mangless nominees.

Zevra shareholders are reminded that their vote is extremely important, no matter how many shares they own. The Company advises that shareholders DO NOT vote for any of the Mangless nominees, and vote “AGAINST” the Mangless Proposal. Instead, the Zevra Board of Directors unanimously recommends shareholders vote “FOR” all of the nominees listed on the WHITE proxy card enclosed with the previously mailed definitive proxy statement.

Shareholders are urged to vote their shares TODAY, in advance of the Annual Meeting. Shareholders can switch their vote at any time to vote “FOR” all of the Company’s Board nominees. Only the latest-dated proxy card counts.
