GNC GNC Holdings Inc

THE SPECIAL MEETING DATE HAS BEEN EXTENDED – AGAIN – TO MAY 17, 2018

EVERY VOTE COUNTS!

On May 9, GNC Holdings, Inc. (the “Company” or “GNC”) once again adjourned its Special Meeting of Stockholders until 10:00 A.M., Eastern Time, on May 17, 2018 to allow stockholders more time to vote and enable the Company to obtain the necessary additional votes to approve the important proposal described below.

Since holders of only approximately 45% of the outstanding shares of the Company’s common stock submitted proxies to vote, the necessary quorum of a majority of the outstanding shares was not reached.

It is critical that a few more stockholders – like you – submit their vote.

GNC encourages all stockholders to vote their shares as soon as possible, but by no later than 11:59 p.m., Eastern Time, on Tuesday, May 16, 2018.

At the time we adjourned, over 93% of the proxies received authorized a vote in favor of the issuance of convertible preferred shares to Harbin Pharmaceutical Group Holdings Co., Ltd (“Hayao”) in connection with Hayao’s $300 million strategic investment in the Company.

We cannot complete this important transaction without your vote. Hayao’s investment is a critical step in our efforts to optimize our capital structure and position GNC to drive growth, improve financial performance and enhance long-term shareholder value.

A duplicate proxy form is enclosed with this mailing. Please take the time to vote your shares via telephone or internet by following the instructions on the enclosed proxy form.

If you have any questions or need assistance voting your shares, please contact our solicitors, MacKenzie Partners, Inc. toll-free at (800) 322-2885 or Georgeson LLC by calling toll-free at (888) 607-9107.

Very truly yours,

Kenneth A. Martindale

Chief Executive Officer
