Item 1.01          Entry into a Material Definitive Agreement

Proposed Acquisition of opTricon GmbH

On October 17, 2018, we entered into a share purchase agreement pursuant to which we agreed to acquire all of the outstanding shares of opTricon GmbH, or opTricon, for a purchase price of $5.5 million in cash. We refer to the share purchase agreement as the Purchase Agreement and to the transaction as the Proposed Acquisition. The Proposed Acquisition is scheduled to close on October 31, 2018, subject to standard closing conditions. The Purchase Agreement contains customary representations and warranties from us and from opTricon. Of the purchase price to be paid at closing, $100,000 will be held in escrow for a purchase price adjustment based on the working capital of opTricon and $750,000 will be held in escrow to satisfy certain claims that we may make against the sellers in accordance with the terms of the Purchase Agreement.

opTricon, based in Berlin, Germany, is a developer and manufacturer of handheld analyzers for rapid diagnostic tests. Since 2015 we and opTricon have been parties to an agreement under which we have collaborated in developing our DPP Micro Reader, a handheld, battery-operated analyzer that uses an innovative image sensor to provide, when combined with our DPP tests, a quantitative interpretation of diagnostic results. We intend that opTricon will become a Chembio Center-of-Excellence for optical technology and will serve as our European headquarters. As part of its ongoing business, opTricon will continue to develop and manufacture hand-held analyzers for original equipment manufacturers that do not compete with us. The DPP Micro Reader is included in most of our new product development initiatives and regulatory approvals and submissions. If we complete the Proposed Acquisition, we will secure global commercial rights to opTricon’s offerings and technology and we will be able to produce DPP Micro Readers at a reduced cost, thereby enabling us to promote DPP tests and DPP Micro Readers more actively across global markets.

We cannot assure you that the Proposed Acquisition will close on the scheduled date or at all, or that we will achieve the intended benefits from the Proposed Acquisition.

Item 2.02          Results of Operations and Financial Condition

Third Quarter 2018 Revenue

We preliminarily estimate that revenue for the third quarter of 2018 will be in the range of $9.2 million to $9.4 million, an increase of 21.3% to 23.9% from revenue of $7.6 million in the third quarter of 2017.
The range for revenue for the third quarter of 2018 represents a preliminary estimate because our financial closing procedures for the quarter remain to be performed and other developments may arise by the time the financial results for the quarter are completed. As a result, there is a possibility that revenue will not be within the range we currently estimate. This information is provided by and is the responsibility of management. Our independent registered public accounting firm has not audited, reviewed, compiled or performed any procedures with respect to this information and, accordingly, does not express an opinion or any other form of assurance on it.

Item 8.01          Other Events

Grant of Equity Awards

On October 8, 2018, the compensation committee of the board of directors made awards of restricted stock and restricted stock units under our 2014 Stock Incentive Plan to our four current non-employee directors and our six current executive officers, for an aggregate of 261,657 shares of common stock. Of the shares of common stock awarded, (a) 7,772 shares of restricted stock were awarded to each of Katherine L. Davis, Gail S. Page, Mary Lake Polan and John G. Potthoff, who comprise our non-employee directors; (b) shares of restricted stock were awarded to executive officers as follows: Javan Esfandiari; 38,860; Neil A. Goldman, 31,088; David Gyorke, 20,725; Sharon Klugewicz, 20,725; and John J. Sperzel III, 98,446; and (c) restricted stock units covering 20,725 shares of common stock were awarded to executive officer Robert Passas.  Awards to non-employee directors vest based on continued service for one year after grant, and awards to key employees vest in three annual installments.

The awards were made in connection with the compensation committee’s review of our executive and director compensation programs with its independent compensation consultant, Pearl Meyer & Partners, LLC, and are intended to continue to (a) improve alignment of interests of our directors and executive officers with our long-term stockholders, taking into account our history of limited and occasional equity compensation awards, and (b) facilitate our retention of key leaders to better ensure a stable management team focused on long-term growth goals. The compensation committee’s review of our executive compensation programs is an ongoing process and additional changes to those programs may be made in the future.

Purchase Commitment from Bio-Manguinhos

On September 4, 2018, we received a $10.5 million commitment from Bio-Manguinhos to purchase test components and intermediate product for the production of DPP HIV and DPP Leishmania assays in Brazil and their subsequent supply to Brazil's Ministry of Health. We expect to supply these items during 2019. Bio-Manguinhos, a subsidiary of the Oswaldo Cruz Foundation (also known as Fiocruz), is responsible for the development and production of vaccines, diagnostics and biopharmaceuticals, primarily to meet the demands of Brazil's national public health system.  We have a long-standing relationship with Bio-Manguinhos, supplying multiple products for point-of-care detection of HIV and other infectious diseases.

Updated Summary of Our Business
Chembio Diagnostics, Inc. is a leading provider of point-of-care diagnostic products for the detection and diagnosis of infectious diseases. We have been expanding our product portfolio based upon our proprietary DPP technology platform, which uses a small drop of blood from the fingertip to provide high-quality, cost-effective diagnostic results in approximately 15 minutes. We seek to build additional revenue streams by entering into strategic collaborations with leading global healthcare companies in order to leverage the DPP platform.
Compared with traditional lateral flow technology, the DPP technology platform provides enhanced sensitivity and specificity, advanced multiplexing capabilities, and, when used with the DPP Micro Reader, quantitative results. Our DPP HIV test provides sensitivity of 99.8% and specificity of 100%, and has been approved by the U.S. Food and Drug Administration, or FDA, and approved as a waived test under the Clinical Laboratory Improvement Amendments of 1988.
We are pursuing four corporate priorities, aimed at executing on our key building blocks to drive growth and operating efficiency:
expand our core point-of-care infectious disease business;
leverage our patented DPP technology and scientific expertise through collaborations;
broaden our sales channels worldwide; and
automate our U.S. manufacturing operations to increase capacity and margin.


The DPP technology platform addresses the lateral flow test market, which includes infectious diseases, cardiac markers, cholesterol and lipids, pregnancy and fertility, and drugs of abuse. Based on our review of third-party reports and other information, we estimate that the market for lateral flow tests will increase from $5.5 billion in 2017 to $8.2 billion in 2022, representing a compound annual growth rate of 8.2%.

Infectious disease tests constitute the largest, and fastest growing, segment of the lateral flow test market. We currently are targeting lateral flow test solutions for three areas of infectious diseases: sexually transmitted disease, mosquito-borne disease and hepatitis. The market for lateral flow infectious disease tests is being driven by the high prevalence of infectious diseases globally, an increase in the geriatric population, growing demand for rapid test results, and advancements in multiplexing. Based on our review of third-party reports and other information, we estimate that the market for lateral flow infectious disease tests will increase from $1.4 billion in 2017 to $2.3 billion in 2022, representing a compound annual growth rate of 10.7%.


Our point-of-care infectious disease portfolio is comprised of multiple commercial products, each serving unique customer requirements. The key advantages of our products include:
only a tiny drop of blood from the fingertip is required;
reliable test results are provided in approximately 15 minutes; and
based on our advanced multiplexing, results for more than one disease can be obtained from a single test.

We have obtained U.S. and, directly or through our partners, selected international regulatory approvals for infectious disease tests as follows:
DPP HIV-Syphilis
DPP Syphilis Screen & Confirm
DPP Zika
DPP Leishmaniasis
SURE CHECK HIV 1/2 Self Test

Organic growth in our core infectious disease business is being driven by:
growth in the overall market for lateral flow infectious disease tests, which we estimate will increase at an compound annual growth rate of 10.7% through 2022 (see “––Industry” above);
our increased market penetration in existing markets and channels, including in the United States, Brazil, Africa and Europe;
our registration of existing and new products in unchartered countries and regions, such as Latin America and Southeast Asia;
our entry into new market segments, such as international HIV Self-Testing; and
advances in our product pipeline in sexually transmitted disease and fever and tropical disease, with key products including a multiplex test for HIV and syphilis in the U.S. market and tests for chikungunya, dengue, malaria and Zika.

We market and sell both individual and multiplex tests for sexually transmitted infectious diseases, such as HIV and syphilis. HIV and syphilis continue to be major global public health issues. According to World Health Organization estimates:
HIV has claimed more than 35 million lives, including 940,000 in 2017. Approximately 36.9 million were living with HIV at the end of 2017, and 1.8 million were newly infected during 2017.
There were 18.0 million prevalent cases of syphilis as of 2012, and 5.6 million new infections were estimated to occur annually.
Elimination of mother-to-child transmission, or MTCT, of both HIV and syphilis is a global health priority. In 2013, 1.9 million pregnant women were infected with syphilis worldwide. Congenital syphilis contributes significantly to infant mortality, accounting for 305,000 annual perinatal deaths worldwide in 2013. Globally, more than 1.4 million pregnant women were infected with HIV as of 2015, and MTCT of HIV is estimated to have resulted in over 150,000 infant cases in 2015.
We are seeking to address the global concerns related to HIV and syphilis co-infection through the development of a novel, multiplex test for both HIV and syphilis. We have developed a DPP HIV-Syphilis multiplex test and received regulatory approvals covering a number of international markets, including Brazil, Europe, Malaysia and Mexico. In the United States we have completed a clinical trial and filed a Pre-Market Approval Application with the FDA, which is in the review process. We believe we are well-positioned to be the first company to introduce a multiplex rapid test for HIV and syphilis.

We also market and sell tests for selected fever and tropical diseases, such as Chagas, leishmaniasis and Zika. The market for lateral flow testing for tropical and fever disease includes established markets for disease such as dengue and malaria, which the World Health Organization estimates together account for more than 600 million infections worldwide annually. There are also a number of emerging markets for lateral flow tests for diseases such as burkholderia, chikungunya, ebola, lassa, leptospirosis, Marburg, rickettsia and Zika. We are developing tests, using the DPP platform, to detect all of the aforementioned tropical and fever diseases, as stand-alone or multiplex assays.

Since 2015 we have received over $9 million of funding from some of the world’s leading health organizations, which has helped us accelerate the expansion of our pipeline of infectious disease tests. Our collaborators have included Bill & Melinda Gates Foundation, The Paul G. Allen Family Foundation, Oswaldo Cruz Foundation (Fiocruz) and FIND, as well as U.S. government agencies such as Centers for Disease Control and Biomedical Advanced Research and Development Authority (U.S. Department of Health and Human Services). Many of the tests in our infectious disease pipeline are approaching commercialization, and several have received initial regulatory approvals:

We are building additional revenue streams by leveraging our patented DPP technology and scientific expertise through collaborations. Leading global healthcare organizations have chosen to collaborate with us based on our deep scientific expertise with our proven DPP technology platform and capabilities, our successful record of developing DPP tests with a diverse set of collaborators including global commercial companies, governments and non-governmental organizations, and our extensive experience in obtaining regulatory approvals in the United States (FDA), Brazil (ANVISA), the European Union (CE mark) and Mexico (COFEPRIS), as well as from the World Health Organization (Prequalification, or PQ).

By leveraging our DPP technology platform, we are creating opportunities to expand into new markets such as cancer diagnostics, concussion and traumatic brain injury, and veterinary and we are broadening the application of our technology from point-of-care diagnostics to include companion diagnostics. Research and development costs related to the collaborations are fully funded by our collaborators.

Sales Channels

Our products are sold globally, both directly and through distributors, to hospitals and clinics, physician offices, clinical laboratories, public health organizations, government agencies and consumers. Historically, we marketed and sold our products only into a handful of countries and regions. In recent years we have hired a small number of sales executives to begin building our own channels in key markets such as the United States, Europe, Latin America, Africa and Southeast Asia. With sales growth as an underlying objective, we are focused on increasing sales in existing geographies, expanding sales into new geographies, and broadening sales coverage in key markets.

Automation of U.S. Manufacturing

We are automating our U.S. manufacturing processes and expanding our manufacturing capacity. In late June 2018, we received delivery of our first automated line of manufacturing equipment, which we expect will commence production during the fourth quarter of 2018. This automated manufacturing line will be used for DPP test production and will allow assembly of various configurations of DPP tests on the line. The automated line will have an annual capacity of between five and ten million tests, depending on the test configuration, and will use vision-guided, robotic operation to improve inspection and quality control. As we transition from total manual to automated assembly, we believe the reduced variable costs can help drive product margin improvement.
