Protalix BioTherapeutics Announces 1-for-10 Reverse Stock Split

CARMIEL, Israel, Dec. 9, 2019 /PRNewswire/ -- Protalix BioTherapeutics, Inc. (NYSE American: PLX) (TASE: PLX), a biopharmaceutical company focused on the development, production and commercialization of recombinant therapeutic proteins produced by its proprietary ProCellEx^® plant cell-based protein expression system, today announced that, at the Company's Special Meeting of Stockholders, its stockholders approved an amendment to the Company's Certificate of Incorporation, as amended, to effect a reverse stock split at a ratio of 1‑for‑10 and to reduce the total number of authorized shares of the common stock from 350 million shares to 120 million shares.

"We want to thank our stockholders for this important vote and show of support for the Company," said Dror Bashan, Protalix's President and Chief Executive Officer. "This action is part of our plan to regain compliance with the continued listing guidelines of the NYSE American. We believe that the reverse stock split will result in our common stock being more attractive to a broader range of institutional and other investors which should further build value for our stockholders."

The 1‑for-10 reverse stock split of the Company's common stock is scheduled to become effective at midnight, December 19, 2019. Beginning on December 20, 2019, the Company's common stock will trade on the NYSE American on a post-split basis under a new CUSIP number, 74365A 309. The Company's common stock will continue to trade on the NYSE American under the symbol "PLX".

Upon effectiveness of the reverse stock split, every 10 shares of the Company's outstanding common stock will be converted to one share of common stock. In addition, a proportionate adjustment will be made to the per share exercise price and the number of shares issuable upon the exercise of all outstanding options entitling the holders to purchase common stock and to the conversion ratio of the Company's outstanding 7.5% convertible promissory notes due 2021.

The reverse stock split will not affect any stockholder's ownership percentage of the Company's common stock, except to the extent that the reverse stock split would result in any stockholder owning a fractional share. No fractional shares will be issued in connection with the reverse stock split. The number of outstanding shares will be reduced from approximately 148.38 million shares to approximately 14.84 million shares.

Registered stockholders holding their shares of common stock in book-entry or through a bank, broker or other nominee form do not need to take any action in connection with the reverse stock split. For those stockholders holding physical stock certificates, the Company's transfer agent, American Stock Transfer & Trust Company, LLC, will send instructions for exchanging those certificates for new certificates representing the post-split number of shares. American Stock Transfer & Trust Company, LLC can be reached at 877-248-6417 (toll free) or 718-921-8317.

About Protalix BioTherapeutics, Inc.

Protalix is a biopharmaceutical company focused on the development and commercialization of recombinant therapeutic proteins expressed through its proprietary plant cell-based expression system, ProCellEx^®. Protalix was the first company to gain U.S. Food and Drug Administration (FDA) approval of a protein produced through plant cell-based in suspension expression system. Protalix's unique expression system represents a new method for developing recombinant proteins in an industrial-scale manner.
