Chembio Stockholders Reminded to Tender Shares Before 6:00 PM New York City Time, on March 28, 2023

MEDFORD, N.Y., March 21, 2023 (GLOBE NEWSWIRE) -- Chembio Diagnostics, Inc. (NASDAQ:CEMI), a leading point-of-care diagnostics company focused on infectious diseases, today released the following letter to stockholders concerning the pending tender offer by Biosynex SA.

Fellow Chembio Stockholders,

As previously disclosed, Chembio Diagnostics, Inc. ("Chembio" or the "Company") entered into an Agreement and Plan of Merger (the "Merger Agreement"), dated as of January 31, 2023, with Biosynex SA, a French société anonyme ("Biosynex"), and Project Merci Merger Sub, Inc., a Nevada corporation and wholly-owned indirect subsidiary of Biosynex (the "Purchaser"). Pursuant to the Merger Agreement, the Purchaser commenced a tender offer (the "Offer") to purchase all of the issued and outstanding shares of the Company's common stock, par value $0.01 per share (the "Shares"), for a purchase price of $0.45 per share, net to the seller in cash, without interest and subject to any required tax withholding. On March 15, 2023, Biosynex announced an extension of the Offer until 6:00 p.m., New York City time, on March 28, 2023.

I am reaching out to remind you to tender your shares prior to the expiration of the Offer on March 28, 2023. If less than a majority of the outstanding shares of Chembio common stock are tendered, the Offer will not be completed and Chembio will not merge with Biosynex.

What Happens If Stockholders Don't Tender Their Shares:

There are substantial risks to Chembio remaining an independent company if the Offer and merger between Biosynex and Chembio are not completed. As discussed in further detail in the Schedule 14D-9 and the Company's letter to stockholders dated March 15, 2023, the risks faced by the Company include:

• Breaching a financial covenant in its Credit Agreement that could force the Company to pursue a transaction or financing arrangement that is highly dilutive to existing stockholders or a bankruptcy or restructuring proceeding;
  
  
  
  
• Being delisted by Nasdaq as soon as April 2023; and
  
  
  
  
• The Company's ability to continue as a going concern due to its net losses from operations and ongoing liquidity concerns.
  
  

How to Tender Your Shares:

If you hold shares of Chembio common stock through a broker, dealer, commercial bank, trust company or other nominee, instruct such broker or other nominee to tender your shares. Please do so promptly to allow sufficient time to meet any broker processing deadlines before the Offer expiration at 6:00 p.m. New York City time on March 28, 2023. Do not wait until the Offer expires to tender your shares.
