STRASBOURG, France and HAUPPAUGE, N.Y., Jan. 31, 2023 (GLOBE NEWSWIRE) -- Biosynex SA (“Biosynex”) (EPA: ALBIO), a French market leader specializing in the design and distribution of rapid tests, and Chembio Diagnostics, Inc. (“Chembio”) (Nasdaq: CEMI), a leading point-of-care diagnostics company focused on infectious diseases, today announced that the companies have entered into a definitive merger agreement under which Biosynex, through a subsidiary, will acquire Chembio for $0.45 per share, representing a premium of 27% compared to the closing price of Chembio stock on January 30, 2023, in an all-cash transaction valued at $17.2 million.

The acquisition combines two leading rapid diagnostic test companies. Each company specializes in the development, manufacturing and marketing of point-of-care diagnostic tests for the professional and at home markets. Chembio, based in the United States, focuses on infectious disease assays covering sexually transmitted infections, respiratory viruses and fever and tropical disease, built on the DPP, SURE CHECK and STAT-PAK proprietary, accurate and easy-to-use technology platforms. Biosynex, based in France, provides pharmacies and professional healthcare settings with a diversified portfolio of rapid tests covering different market segments including infectious disease and women’s health tests, Point of Care devices and molecular diagnostics systems. Biosynex will operate Chembio and its 100% owned German, Brazil and Malaysia subsidiaries as a wholly owned group.

“The acquisition of Chembio significantly advances our mission to develop, manufacture and market rapid diagnostics for screening, diagnosis and prevention to facilitate patient care and monitor health,” said Larry Abensur, Chief Executive Officer of Biosynex. “Chembio’s portfolio of diagnostic solutions and technology platforms complement our current test portfolio. DPP, SURE CHECK and STAT-PAK are clinically validated with accurate results, ease-of-use, and U.S. FDA and global regulatory approvals including CE marked and WHO prequalified products to provide transformative commercial opportunities that can represent meaningful growth drivers over the near and long-term. Additionally, there are numerous strong synergies across our businesses that can be leveraged to create significant cost savings as a scaled organization. We are excited to enhance our position as key European player for professional point-of-care and self-test diagnostics.”

“Chembio is pleased about the opportunity to become part of Biosynex, uniting two companies that provide healthcare professionals and individuals with innovative diagnostic solutions intended to accelerate care,” said Richard L. Eberly, President and Chief Executive Officer of Chembio. “The backing of BIOSYNEX will enable Chembio to secure its financial needs and the synergies expected from this combination are aiming at returning the business to profitability. I believe this transaction can benefit customers, employees and patients, while creating value as the combined company can offer the expertise, scale and resources to expand the impact of Chembio’s technology.”

Strategic Benefits of the Merger

  • Chembio’s differentiated tests enhance the Biosynex rapid diagnostic portfolio. Chembio’s sexually transmitted infection, tropical and fever and respiratory assays complement Biosynex’s current virology portfolio to create a more comprehensive offering.
  • The Chembio commercial infrastructure broadens the Biosynex footprint globally. The combined commercial team and distribution partners expand Biosynex’s presence in the United States, Brazil, Africa and Asia as well as bolster Biosynex’s European network.
  • Accelerating and enhancing product development. Combining the expertise of two industry leaders to drive product innovation and development along with global regulatory expertise will help to continue expansion of the product portfolio.
  • Consolidation of operations offers potential cost savings, synergies and value creation. The combined organization can leverage increased manufacturing scale, consolidated operating overhead, reduced public company and administrative costs to potentially improve product gross margins and operating margins.

Transaction Details
Under the terms of the merger agreement, Biosynex, through a subsidiary, will initiate a tender offer to acquire all outstanding shares of Chembio. The closing of the tender offer will be subject to certain conditions, including the tender of shares representing at least a majority of the total number of Chembio’s outstanding shares and other customary conditions. Upon the successful completion of the tender offer, Biosynex’s acquisition subsidiary will be merged into Chembio, and any remaining shares of common stock of Chembio will be canceled and converted into the right to receive the same $0.45 per share price payable in the tender offer. The transaction is expected to close in the first quarter of 2023. The terms of the merger agreement were unanimously approved by the Boards of Directors of both companies, and the Board of Directors of Chembio intends to recommend the transaction to Chembio’s stockholders.
