VCNX Vaccinex Inc

Vaccinex, Inc., (NASDAQ: VCNX), a clinical-stage biotechnology company pioneering a differentiated approach to treating neurodegenerative disease and cancer through the inhibition of SEMA4D, today announced that it will effect a 1-for-14 reverse stock split of its issued common stock, effective at 5:00 p.m. Eastern Time on Monday, February 19, 2024. Beginning Tuesday, February 20, 2024, the Company's common stock will trade on a split-adjusted basis.

At the Company's Special Meeting of Stockholders held on February 8, 2024, the Company's stockholders approved a proposal to authorize a reverse stock split of the Company’s common stock, at a ratio of 1-for-4, 1-for-6, 1-for-8, 1-for-10, 1-for-12, and 1-for-14, as to be determined by the Company's Board of Directors. The Board of Directors approved a 1-for-14 reverse split ratio, and on Wednesday, February 14, 2024, the Company filed a Certificate of Amendment to its Amended and Restated Certificate of Incorporation to effect the reverse stock split effective as of 5:00 p.m. Eastern Time on Monday, February 19, 2024 (the “Effective Time”).

The Company's Board of Directors implemented the reverse stock split with the objective of regaining compliance with the $1.00 minimum bid price requirement of The Nasdaq Capital Market. The Company has until March 4, 2024 to comply with this requirement. To evidence compliance with this requirement, the closing bid price of the Company’s common stock must be at least $1.00 per share for a minimum of 10 consecutive business days by March 4, 2024.

The Company's shares of common stock will continue to trade on The Nasdaq Capital Market under the symbol "VCNX." The new CUSIP number for the Company's common stock post-reverse stock split is 918640301.

As a result of the reverse stock split, every fourteen shares of the Company’s common stock will automatically be combined into one share of common stock. The reverse stock split will affect all stockholders uniformly and will not alter any stockholder’s percentage ownership interest in the Company’s equity, except to the extent that the reverse stock split results in any of our stockholders receiving whole shares in lieu of fractional shares, as discussed below. Any fraction of a share of common stock that would be created as a result of the reverse stock split will be rounded up to the next whole share. There will not be a reduction in the total number of authorized shares of common stock.

As of the Effective Time, the number of shares of common stock available for issuance under the Company’s equity incentive plans and issuable pursuant to equity awards immediately prior to the reverse stock split will be proportionately adjusted by the reverse stock split. The exercise prices of the Company’s outstanding options will be adjusted in accordance with their respective terms.

The combination of, and reduction in, the number of issued shares of common stock as a result of the reverse stock split will occur automatically at the Effective Time without any additional action on the part of our stockholders. The Company's transfer agent, Computershare, Inc., is acting as the exchange agent for the reverse stock split and will send stockholders a transaction statement indicating the number of shares of common stock stockholders hold after the reverse stock split. Stockholders owning shares via a broker, bank, trust or other nominee will have their positions automatically adjusted to reflect the reverse stock split, subject to such broker’s particular processes, and will not be required to take any action in connection with the reverse stock split. Additional information regarding the reverse stock split is available on the Form 8-K filed today, as well as in the Company’s definitive proxy statement filed with the Securities and Exchange Commission on January 8, 2024, a copy of which is available at www.sec.gov and on the Company's website.

About Vaccinex Inc. Vaccinex, Inc. is pioneering a differentiated approach to treating slowly progressive neurodegenerative diseases and cancer through the inhibition of semaphorin 4D (SEMA4D). The Company’s lead drug candidate, pepinemab, blocks SEMA4D, a potent biological effector that it believes triggers damaging inflammation in chronic diseases of the brain and prevents immune infiltration into tumors. In neurodegenerative diseases, pepinemab is being studied as a monotherapy in the Phase 1/2a SIGNAL-AD study in Alzheimer’s Disease, with ongoing exploration of potential Phase 3 development in Huntington’s disease. In oncology, pepinemab is being evaluated in combination with KEYTRUDA® in the Phase 1b/2 KEYNOTE-B84 study in recurrent or metastatic head and neck cancer (HNSCC) and in combination with BAVENCIO® in a Phase 1b/2 study, supported by funding from Gateway Discovery Foundation, in patients with metastatic pancreatic adenocarcinoma (PDAC). The oncology clinical program also includes several investigator-sponsored studies in solid tumors including breast cancer and melanoma.
