#### Cautionary Statement Regarding Forward Looking Statements

This filing contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Forward-looking statements involve inherent risks and uncertainties and you are cautioned that a number of important factors could cause actual results to differ materially from those contained in any such forward-looking statement. These statements can otherwise be identified by the use of words such as "anticipate," "believe," "could," "estimate," "expect," "feel," "forecast," "intend," "may," "plan," "potential," "predict," "project," "seek," "should," "would," "will," and similar expressions intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. The forward-looking statements contained in this filing include, but are not limited to, statements related to Biosynex's and Chembio's plans, objectives, expectations and intentions with respect to the proposed transaction and the combined company, the anticipated timing of the proposed transaction, the conditions precedent to the closing of the proposed transaction and the potential impact the transaction will have on Chembio or Biosynex and other matters related to either or both of them. The forward-looking statements are based on assumptions regarding current plans and estimates of management of Biosynex and Chembio. Such management believes these assumptions to be reasonable, but there is no assurance that they will prove to be accurate.

Factors that could cause actual results to differ materially from those described in this filing include, among others: changes in expectations as to the closing of the transaction including timing and changes in the method of financing the transaction; the satisfaction of the conditions precedent to the consummation of the proposed transaction (including a sufficient number of Chembio shares being validly tendered into the tender offer to meet the minimum condition); the risk of litigation and regulatory action related to the proposed transactions; expected synergies and cost savings are not achieved or achieved at a slower pace than expected; integration problems, delays or other related costs; retention of customers and suppliers; and unanticipated changes in laws, regulations, or other industry standards affecting the companies; and other risks and important factors contained and identified in Chembio's filings with the SEC, including its Quarterly Reports on Form 10-Q and Annual Reports on Form 10-K.

The foregoing list of factors is not exhaustive. Readers are cautioned not to place undue reliance on any forward-looking statements, which speak only as of the date hereof. Readers are urged to carefully review and consider the various disclosures, including but not limited to risk factors contained in Chembio's Annual Reports on Form 10-K and its quarterly reports on Form 10-Q, as well as other filings with the SEC. Forward-looking statements reflect the analysis of management of Biosynex and Chembio as of the date of this filing. Neither Biosynex nor Chembio undertakes to update or revise any of these statements in light of new information or future events, except as expressly required by applicable law.

#### Exhibit 99.2

**Subject:** Exciting Next Step for Chembio!

Dear Chembio Colleagues,

Today marks the beginning of an exciting next step for Chembio! As just announced publicly, we have entered into a definitive agreement to be acquired by Biosynex SA ("Biosynex"), 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. More details are included in the press release [insert hyperlink] issued today.

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. Our focus is 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. The acquisition is expected to close by the end of the first quarter of 2023 subject to customary closing conditions. Following completion of the acquisition, Biosynex will operate Chembio and its 100% owned German, Brazil and Malaysia subsidiaries as a wholly owned group.

The backing of Biosynex will enable Chembio to secure its financial needs and the synergies expected from this operation are aiming at returning the business to profitability which benefits 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.

#### Next Steps – Town Hall Meetings

Please join me along with other members of Executive Leadership team tomorrow for Town Hall meetings. An invite will be sent out shortly.

As for next steps, we expect to complete this combination with Biosynex by the end of the first quarter of 2023, subject to customary closing conditions. I want to emphasize that until then, Chembio and Biosynex will continue to operate as separate companies, and it's business as usual. Your role and day-to-day responsibilities remain unchanged, and we're counting on you to continue building on the strong momentum we have underway. We're also committed to keeping you informed as best we can throughout this process. An FAQ is also attached in this email and feel free to direct any questions to your respective Executive Leadership Team manager. Until the transaction is completed, we continue as a public company and all company guidelines must continue to be followed.

Today's announcement is a testament to the incredible people and technology at Chembio. It's due to your dedication to serving our customers and delivering quality products - every single day! I couldn't be prouder of the company we have built together and excited for Chembio's future.

Best Regards,

Rick
