Chembio Diagnostics Reports Third Quarter 2016 Financial Results

Conference Call and Webcast Today at 10:00 a.m. Eastern Time

MEDFORD, NY, November 10, 2016 -- Chembio Diagnostics, Inc. (Nasdaq:CEMI), a leader in point-of-care ("POC") diagnostic tests for infectious diseases, today reported financial results for the three and nine months ended September 30, 2016.

John J. Sperzel III, Chief Executive Officer, stated, "The Company made important advances in multiple areas during the third quarter of 2016, intended to prepare the Company for growth: commercialization, regulatory approvals, product development grants, and equity financing. With respect to Chembio's commercial infrastructure, the Company appointed two seasoned executives to build our worldwide sales and marketing capabilities, with immediate focus on the United States, Latin America, Asia Pacific and Africa. The Company expanded its distribution network by appointing Isla Lab, the largest distributor of diagnostic products in the Caribbean, as its exclusive distributor in that region.

"Chembio recently secured two important regulatory approvals. In July 2016, the Company obtained a CE mark for the DPP^®Zika IgM/IgG Assay and DPP^®Micro Reader, allowing the products to be marketed and sold in 17 European countries, including the United Kingdom, Germany, and France, as well as a majority of the Caribbean nations. In late October 2016, the Company received approval by Brazil's health regulatory agency, Agência Nacional de Vigilância Sanitária (ANVISA) for DPP^® Zika IgM/IgG Assay. These regulatory achievements follow the milestone which occurred at the end of the second quarter of 2016, when Chembio's DPP^® HIV 1/2 Assay was accepted for the World Health Organization (WHO) list of prequalified in vitro diagnostics.

"In August 2016, Chembio completed an equity financing which provided gross proceeds of approximately $13.8 million, which provides the Company with capital needed to advance its product development programs and invest in the sales and operational infrastructure needed to support sustained growth. Also in August 2016, Chembio was awarded a contract for up to $13.2 million in total funding from the U.S. Department of Health and Human Services (HHS); Office of the Assistant Secretary for Preparedness and Response (ASPR); Biomedical Advanced Research and Development Authority (BARDA) to develop and commercialize the Company's DPP^® Zika IgM/IgG Assay and Zika-related products.

"Subsequent to the 2016 third–quarter end, Chembio entered into an agreement to acquire RVR Diagnostics Sdn Bhd (RVR), a Malaysian, privately-held manufacturer and distributor of POC diagnostic tests for infectious diseases. Subject to satisfaction of conditions to closing, completion of the RVR acquisition will provide the Company with a strategically located and cost-effective manufacturing facility, an additional revenue source, and the potential to accelerate important product registrations in Southeast Asia, which we believe will be important in serving a number of global markets."

Addressing the company's financial results, Mr. Sperzel commented, "Despite reporting a decrease in product sales for both the second and third quarters of 2016, a quarter-over-quarter analysis shows sales growth with total revenues for the third quarter of 2016 up 15% and product sales for the third quarter of 2016 up 23%, as compared to the second quarter of 2016. In the United States, sales of the HIV 1/2 STAT-PAK^® Assay increased 44% as compared to the third quarter of 2015, and increased 21% as compared to the second quarter of 2016. This growth provides strong evidence that we are effectively rebuilding the U.S. HIV STAT-PAK^® business, since we took back the U.S. distribution rights to this product in June 2014. We are also seeing encouraging U.S. sales of the HIV 1/2 SURE CHECK^® Assay since we took back distribution rights to this product at the end of May 2016. Through the Company's achievements in strengthening commercial infrastructure, securing regulatory approvals, improving its balance sheet, obtaining a multi-million dollar grant from the U.S. Government, and establishing operations in the growing Asian market, we believe Chembio is on a path to establish a global operation with potential for growth in several important markets."

Additional Financial Information

Third Quarter:

Total revenues in the 2016 third quarter of $3.75 million decreased 45.6% compared with $6.89 million in the prior-year period. Product sales in the 2016 third quarter of $2.50 million decreased 59.7% compared with $6.21 million in the prior-year period. R&D milestone, and grant and royalty revenues in the 2016 third quarter of $1,244,000 increased 83.4% compared with $678,000 in the prior-year period.

Gross margin dollars in the 2016 third quarter of $1.95 million decreased 32.9% compared with $2.91 million in the prior-year period, due primarily to decreased product revenues. Product gross margin dollars in the 2016 third quarter of $0.71 million decreased 68.3% compared with $2.23 million in the prior-year period, which also was primarily due to the decreased product revenues.

R&D expenses in the 2016 third quarter of $2.26 million increased 44.2%, compared with $1.57 million in the prior-year period. This increase is due primarily to increased clinical trial expenses as well as R&D activities for projects and grants.

Selling, general and administrative expenses in the 2016 third quarter of $1.83 million decreased 4.5% compared with $1.92 million in the prior-year period, largely due to decreased commissions, which were due to decreased sales in Brazil, as well as decreases in stock-based compensation, travel, entertainment and trade shows, consulting, and other expenses, which were partially offset by increases in wages and related costs, marketing materials, professional fees and investor relations expenses.

Operating loss in the 2016 third quarter was $2,144,000, compared with an operating loss of $579,000 in the prior-year period.

Net loss in the 2016 third quarter was $2,138,000, or $0.19 per diluted share, compared with net loss of $437,000, or $0.05 per diluted share, in the prior-year period.

First Nine Months:

Product sales in the 2016 first nine months of $10.45 million decreased 42.4% compared with $18.15 million in the prior-year period. R&D milestone, and grant and royalty revenues in the 2016 first nine months of $3,161,000 increased 87.2% compared with $1,689,000 in the prior-year period.

Gross margin dollars in the 2016 first nine months of $6.70 million decreased 22.3% compared with $8.62 million in the prior-year period, due primarily to the decrease in product sales. The amount of product gross margin in the 2016 first nine months of $3.54 million decreased 48.9% compared with $6.93 million in the prior-year period.

R&D expenses in the 2016 first nine months of $6.27 million increased 27.6%, compared with $4.91 million in the prior-year period. This increase is due primarily to increased R&D activities for projects and grants.

Selling, general and administrative expenses in the 2016 first nine months of $5.43 million decreased 10.3%, compared with $6.06 million in the prior-year period, largely due to decreased commissions on sales in Brazil, decreased wages and related costs, stock-based compensation, consulting and travel, entertainment and trade shows, which were partially offset by increases in marketing materials, investor relations expenses and professional fees.

Operating loss in the 2016 first nine months was $4,998,000, compared with an operating loss of $2,352,000 in the prior-year period.

Net loss in the 2016 first nine months was $10,789,000, or $1.06 per diluted share, compared with net loss of $1,748,000, or $0.18 per diluted share, in the prior-year period. The net loss in the 2016 period includes a tax provision for the recording of a valuation allowance on the Company's deferred tax asset of $5,801,000.

Valuation Allowance

The Company elected, based on accounting guidance, to record a full Valuation Allowance ("VA") on its Deferred Tax Asset ("DTA"). Chembio's DTA was primarily based on the Company's Net Operating Loss (NOL) carryforwards. Based primarily on the fact that the Company believes, given information available to it at this time, that it is more likely than not that the deferred tax asset will not be realized in the foreseeable future, the Company concluded that it was appropriate to record a full VA against its DTA. This resulted in a tax provision in the second quarter of 2016 of $5.96 million and for the nine months ended September 30, 2016 of $5.80 million. This VA does not affect the Company's ability to use its NOLs in the future.

Balance Sheet Highlights:

The Company had cash and cash equivalents of $12.17 million as of September 30, 2016, compared with $5.38 million as of December 31, 2015. The increase was primarily due to net cash raised in the sale of common stock, partially offset by cash used in operating activities for the nine months of 2016. Our working capital increased by $8.06 million from $9.48 million as of December 31, 2015 to $17.54 million.

In early August 2016, the Company sold 2,300,000 common shares for a total of $13.8 million, which after expenses resulted in approximately $12.5 million in net funds to the Company.
