ITEM 1.

BUSINESS

Overview

PART I

We  develop  and  commercialize  point-of-care  diagnostic  tests  used  for  the  rapid  detection  and  diagnosis  of  infectious  diseases,  including  sexually
transmitted disease, insect vector and tropical disease, COVID-19 and other viral and bacterial infections, enabling expedited treatment.
Our  product  portfolio  is  based  upon  our  proprietary  DPP  technology,  a  diagnostic  platform  that  provides  high-quality,  cost-effective  results  in  15  to  20
minutes  using  fingertip  blood,  nasal  swabs  and  other  sample  types.  The  DPP  technology  platform  addresses  the  rapid  diagnostic  test  market,  which
includes infectious diseases such as STI’s and HIV, Gastroenterology and Women’s Health. Compared with traditional lateral flow technology, the DPP
technology platform can provide:

•

•

Enhanced sensitivity and specificity: This is achieved via our patented approach to separating the sample path from the buffer path, together with
other patented and proprietary strategies, that differ significantly from traditional lateral flow test.

Advanced multiplexing capabilities: Through advanced multiplexing, the DPP platform can detect and differentiate up to eight distinct test results
from a single patient sample, which can deliver greater clinical value than other rapid tests currently on the market.

• Objective results: For some diagnostic applications, our easy-to-use, highly portable, battery-operated DPP Micro Reader optical analyzers can report
accurate results  in  approximately  15  seconds,  making  it  well-suited  for  decentralized  testing  where  real-time  results  enable  patients  to  be  clinically
assessed while they are still onsite. Objective results produced by the DPP Micro Reader can reduce the possibility of the types of human error that can
be experienced in the visual interpretations required by many rapid tests.

We target the market for rapid diagnostic test solutions for infectious diseases, which is driven by the high prevalence of infectious diseases globally, an
increase in the elderly population, growing demand for rapid test results, and advancements in multiplexing. We have a broad portfolio of infectious disease
products,  which  prior  to  2020  were  focused  principally  on  sexually  transmitted  disease  and  fever  and  tropical  disease.  In  February  2020  we  began  the
process of shifting substantially all of our resources to seek to leverage the DPP technology platform to address the acute and escalating need for diagnostic
testing for COVID-19. We are continuing to pursue:

•

•

•

an emergency use authorization, or EUA, from the U.S. Food and Drug Administration, or FDA, as well as 510(k) clearance from the FDA, for the
DPP SARS-CoV-2 Antigen test system;

an EUA from the FDA for the DPP Respiratory Antigen Panel; and

a Clinical Laboratory Improvement Amendment, or CLIA, waiver from the FDA for the DPP HIV-Syphilis test system.

For additional information about our existing and proposed product offerings, please see “—Products” below. Our products are sold globally, directly and
through distributors, to medical laboratories and hospitals, governmental and public health entities, nongovernmental organizations, medical professionals,
and retail establishments. We continue to seek to expand our commercial distribution channels.

Table of Contents

The extensive economic disruption caused by the COVID-19 pandemic, exacerbated by the market and regulatory complications we faced in seeking to
develop and commercialize a portfolio of COVID-19 test systems, was reflected in our operating results for 2021, as total revenues were $47.8 million, an
increase  of  47.3%  from  2020,  and  net  product  sales  were  $34.8  million,  an  increase  of  40.3%  from  2020.  See  “Item  7.  Management’s  Discussion  and
Analysis of Financial Condition and Results of Operations—Consolidated Results of Operations.”

In 2021 we continued to invest in automating our test manufacturing processes, all of which are now based in the United States. Among other actions, we
expanded our manufacturing capabilities by validating and implementing automated lines. Our transition from manual to automated assembly is intended to
add capacity, reduce variable costs and improve product margins. In order to address challenging economic conditions and implement our business strategy,
we continued to execute a program to  reduce  operating  expenses  and  better  align  our  costs  with  revenues  by  eliminating  positions  that  were  no  longer
aligned with our strategy. Our cash and cash equivalents totaled $28.8 million at December 31, 2021, compared to $23.1 million at December 31, 2020.

The Company’s future working capital needs will depend on many factors, including the rate of its business and revenue growth, the availability and cost of
human,  material  and  other  resources  required  to  build  and  deliver  products  in  accordance  with  its  existing  or  future  product  orders,  the  timing  of  its
continuing automation of manufacturing, and the timing of its investment in research and development as well as sales and marketing. If the Company is
unable to increase its revenues and manage its expenses in accordance with its operating plan, it may need to reduce the level or slow the timing of the
growth  plans  contemplated  by  its  operating  plan,  which  would  likely  curtail  or  delay  the  growth  in  its  business  contemplated  by  its  operating  plan  and
could  impair  or  defer  its  ability  to  achieve  profitability  and  generate  cash  flow,  or  to  seek  to  raise  additional  funds  through  debt  or  equity  financings,
strategic relationships, or other arrangements. All DPP tests are developed and manufactured in the United States and are the subject of a range of domestic
and global patents and patents pending.

Going Concern Considerations

Revenues  during  the  twelve  months  ended  December  31,  2021  did  not  meet  the  Company’s  expectations.  The  Company’s  increase  in  cash  and  cash
equivalents over the year reflected its issuance of common stock in at-the-market offerings for net proceeds of $38.8 million (see Note 9 - Stockholder’s
Equity). The Company continued to experience market, clinical trial and regulatory complications in seeking to develop and commercialize a portfolio of
COVID-19  test  systems  during  the  continuing,  but  evolving,  uncertainty  of  the  COVID‑19  pandemic.  In  the  year  ending  on  December  31,  2021,  the
Company  continued  to  incur  significant  expenses  in  connection  with  pending  legal  matters  (see  Note  12  –  Commitments,  Contingencies,  and
Concentrations:  Litigation),  delayed  achievement  of  milestones  associated  with  government  grant  income,  investments  in  inventory,  and  the  continuing
automation of manufacturing.

The Company performed an assessment to determine whether there were conditions or events that, considered in the aggregate, raised substantial doubt
about the Company’s ability to continue as a going concern within one year after the date the accompanying consolidated financial statements are being
issued. Initially, this assessment did not consider the potential mitigating effect of management’s plans that had not been fully implemented. Because, as
described below, substantial doubt was determined to exist as the result of this initial assessment, management then assessed the mitigating effect of its
plans  to  determine  if  it  is  probable  that  the  plans  (1)  would  be  effectively  implemented  within  one  year  after  the  date  the  accompanying  consolidated
financial statements are issued and (2) when implemented, would mitigate the relevant conditions or events that raise substantial doubt about the entity’s
ability to continue as a going concern.

During the twelve months ended December 31, 2021, the Company undertook measures to increase its total revenues and improve its liquidity position. In
particular,  the  Company  received  significant  purchase  orders  from  two  customers  (the  “July  Purchase  Orders”).  The  Company  had  pursued  the  July
Purchase Orders for an extended period of time. The July Purchase Orders consist of the following:

•

On July 20, 2021, the Company received a $28.3 million purchase order from Bio-Manguinhos for the purchase of DPP SARS-CoV-2 Antigen tests for
delivery during 2021 to support the urgent needs of Brazil’s Ministry of Health in addressing the COVID-19 pandemic. Bio-Manguinhos, is
responsible for the development and production of vaccines, diagnostics and biopharmaceuticals, primarily to meet the demand of Brazil’s national
public health system. As of December 31, 2021 $16.8 million was recognized in connection with this order.

5

Table of Contents

•

On July 22, 2021, the Company received a $4 million purchase order from the Partnership for Supply Chain Management, supported by The Global
Fund, for the purchase of HIV 1/2 STAT-PAK Assays for shipment to Ethiopia into early 2022. As of December 31, 2021 $1.2 million was recognized
in connection with this order.

These measures and other plans and initiatives have been designed to provide the Company with adequate liquidity to meet its obligations for at least the
twelve-month period following the date the accompanying consolidated financial statements are being issued. The Company’s execution of those measures
and its other plans and initiatives continue to depend, however, on factors and uncertainties that are beyond the Company’s control, or that may not be
addressable on terms acceptable to the Company or at all. The Company considered in particular how:

•

•

The ongoing healthcare and economic impacts of the COVID-19 pandemic on the global customer base for the Company’s non‑COVID-19 products
continue to negatively affect the timing and rate of recovery of the Company’s revenues from those products by, for example, decreasing the allocation
of funding for HIV testing, thereby continuing to adversely affect the Company’s liquidity.

Although the Company has entered into agreements to distribute third-party COVID-19 products in the United States, its ability to sell those products
could be constrained because of staffing and supply chain limitations affecting the suppliers of those products.

The Company further considered how these factors and uncertainties could impact its ability over the next year to meet the obligations specified in the
Credit  Agreement  with  the  Lender  (each  as  defined  in  Note  13  –  Long-Term  Debt).  Those  obligations  include  covenants  requiring:  1)  minimum  cash
balance of $3.0 million and ii) minimum total revenue amounts for the twelve months preceding each quarter end. For the next year, the minimum total
revenue requirements range from $42.0 million for the twelve months ending March 31, 2022 to $47.4 million for the twelve months ending December 31,
2022. Upon an event of default under the Credit Agreement, the Lender could elect to declare all amounts outstanding thereunder, together with accrued
interest, to be immediately due and payable. In such an event, there can be no assurance that the Company would have sufficient liquidity to fund payment
of the amounts that would be due under the Credit Agreement or that, if such liquidity were not available, the Company would be successful in raising
additional capital on acceptable terms, or at all, or in completing any other endeavor to continue to be financially viable and continue as a going concern.
The Company’s inability to raise additional capital on acceptable terms in the near future, whether for purposes of funding payments required under  the
Credit  Agreement  or  providing  additional  liquidity  needed  for  its  operations,  could  have  a  material  adverse  effect  on  its  business,  prospects,  results  of
operations, liquidity and financial condition.

Accordingly, management determined the Company could not be certain that the Company’s plans and initiatives would be effectively implemented within
one  year  after  the  date  on  which  the  accompanying  consolidated  financial  statements  are  being  issued.  Without  giving  effect  to  the  prospect  of  raising
additional capital pursuant to the ATM Agreement (as defined in Note 9 – Stockholders’ Equity: Common Stock), increasing product revenue in the near
future  or  executing  other  mitigating  plans,  many  of  which  are  beyond  the  Company’s  control,  it  is  unlikely  that  the  Company  will  be  able  to  generate
sufficient cash flows to meet its required financial obligations, including its debt service and other obligations due to third parties. The existence of these
conditions raises substantial doubt about the Company’s ability to continue as a going concern for the twelve-month period following the date on which the
accompanying audited consolidated financial statements are being issued.

Table of Contents

The  accompanying  audited  consolidated  financial  statements  have  been  prepared  assuming  the  Company  will  continue  as  a  going  concern,  which
contemplates continuity of operations, realization of assets and the satisfaction of liabilities in the normal course of business for the twelve-month period
following the date the accompanying consolidated financial statements are issued. As such, the accompanying audited consolidated financial statements do
not  include  any  adjustments  relating  to  the  recoverability  and  classification  of  assets  and  their  carrying  amounts,  or  the  amount  and  classification  of
liabilities that may result should the Company be unable to continue as a going concern.

Industry

The DPP technology platform targets diagnostic disease states; (1) where rapid diagnosis impacts patient treatment and outcomes; (2) that are underserved
by current diagnostic products due to performance or availability; (3) that present opportunities regionally, demographically or clinically.  The Company is
focused on test solutions associated with infectious diseases: respiratory viruses, sexually transmitted diseases, gastroenterology and insect-vector diseases.

Our product portfolio is marketed globally to NGO’s, Ministries of Health, acute care hospitals, reference labs, outpatient clinics including urgent cares and
physician offices.  Our branded products have secured meaningful market share globally and include, SureCheck, Stat Pak and DPP.  The Company will
focus  on  internally  developed  products  and  pursue  external  opportunities  to  license  novel  technologies  and  products  with  the  intent  of  leveraging
Chembio’s growing commercial infrastructure.

We  currently  are  targeting  lateral  flow  test  solutions  for  infectious  diseases:  respiratory  diseases,  sexually  transmitted  diseases  and  mosquito-borne
diseases. The market for lateral flow infectious disease tests is being driven by the high prevalence of infectious diseases globally, an increase in the elderly
population, growing demand for rapid test results, and advancements in multiplexing.

Products

COVID-19 Diagnostic Test Systems

Prior to 2020, our broad portfolio of infectious disease products was focused principally on sexually transmitted disease and fever and tropical disease. In
2020 we shifted substantially all of our resources to leverage the DPP technology platform to address the acute and escalating need for diagnostic testing
for COVID-19.

COVID-19 Antibody Test System

In January 2021 we announced the CE mark for both the DPP SARS-CoV-2 Antigen test system and the DPP SARS-CoV-2 IgM/IgG test system, providing
regulatory approval to register and market the test systems in the European Union and other geographies that accept the CE mark.

COVID-19 Antigen Test System

In mid-2020 we began to focus on the development of a COVID-19 antigen test system based on DPP technology. In July 2020 we received a $628,071
grant from BARDA to assist us in developing, submitting and obtaining an EUA application for a COVID-19 point-of-care antigen system. In October
2020, with BARDA’s support in accordance with its grant, we submitted to the FDA an EUA application for the DPP SARS‑CoV‑2 Antigen System, a test
system that consists of a DPP SARS-CoV-2 Antigen test cartridge, a DPP Micro Reader optical analyzer and a minimally invasive nasal swab.

7

Table of Contents

In November 2020 ANVISA approved the DPP SARS-CoV-2 Antigen test system for use in Brazil. In January 2021 we announced the CE mark for the
DPP SARS-CoV-2 Antigen test system, providing regulatory approval to register and market the test systems in the European Union and other geographies
that accept the CE mark.

In December 2020 we received a $12.7 million grant from BARDA, in part to support preparation of a submission in pursuit of FDA 510(k) clearance for
the DPP SARS-CoV-2 Antigen System.

In January 2021 the FDA notified us that it was declining to review the DPP SARS-CoV-2 Antigen System based on its updated prioritization guidance,
under which review of the system was not a priority. The FDA has supplementally advised us of the type and nature of information it would need to receive
in  a  subsequent  EUA  application  in  order  for  the  DPP  SARS-CoV-2  Antigen  System  to  be  prioritized  for  review,  and  we  are  engaged  in  testing  and
development in order to submit a new EUA application for a COVID-19 antigen test system.

During the year ending December 31, 2021 we performed the clinical trials and on December 2, 2021 we submitted the DPP SARS‑CoV‑2 Antigen test
system to the FDA, as a de Novo submission.

COVID-19 and Influenza Respiratory Antigen Panel Test System

In the fourth quarter of 2020 we began developing a rapid, multiplex respiratory antigen panel point-of-care test system using DPP technology. BARDA
designated a portion of its $12.7 million grant in December 2020 for use to support our development, submission and receipt of an EUA for this system.

During  2021,  we  developed  and  conducted  clinical  trials  of  the  DPP  Respiratory  Antigen  Panel,  a  test  system  being  designed  to  provide  simultaneous,
discrete and differential detection of Influenza A, Influenza B and SARS-CoV-2 antigens from a single patient respiratory specimen, such as a nasal swab.
The  system  is  intended  to  enable  appropriate  clinical  management  of  patients  with  suspected  respiratory  infections  and  to  assist  in  the  containment  of
COVID-19  cases  during  the  flu  season.  This  test  system  provides  results  in  approximately  20  minutes  and  is  run  on  the  DPP  Micro  Reader.  As  of
December 31, 2021, we have submitted a request for the EUA approval by the FDA which is currently under review. In addition, as of December 31, 2021,
we submitted a request for approval to ANVISA in Brazil and CE in Europe, which has been approved as of the date of this filing.

As a result, we earned $12.5 million of the $12.7 million available under the BARDA Agreement, dated December 2, 2020 with the Biomedical Advanced
Research  and  Development  Authority,  or  BARDA  (part  of  the  U.S.  Department  of  Health  and  Human  Services’  Office  of  the  Assistant  Secretary  for
Preparedness  and  Response)  with  the  remaining  $0.2  million  having  not  been  earned  because  it  was  contingent  on  our  receiving  an  emergency  use
authorization for the DPP SARS-CoV-2 Antigen by December 2, 2021.

HIV-Syphilis Diagnostic Test Systems

On December 1, 2021, we received notice from the FDA that it would require additional data related to our Clinical Laboratory Improvement Amendment,
or CLIA, waiver submission for the DPP HIV-Syphilis test system. We are in active discussions with the FDA in connection with the FDA’s review of our
submission  and  we  intend  to  comply  with  the  FDA’s  request  for  additional  data.  The  process  of  seeking  additional  data  will  extend,  for  a  currently
undeterminable period, our process for seeking a CLIA waiver for the DPP HIV-Syphilis test system.

Organic growth in our core infectious disease business is being driven by:

•
•
•
•
•

growth in the overall market for point of care infectious disease tests;
our increased market penetration in existing markets and channels, including in the United States, Latin America, Africa and Europe;
our registration of existing and new products in unchartered countries and regions, such as selected countries in Latin America and Southeast Asia;
our entry into new market segments, such as respiratory tests and international HIV Self-Testing; and
advances in our product pipeline in infectious disease with key products including tests for COVID-19, a  multiplex test for HIV and syphilis in
the U.S. market and tests for dengue, zika and chikungunya.

We market and sell both stand-alone and multiplex tests for sexually transmitted infectious diseases, such as HIV and syphilis which continue to be major
global public health issues. According to WHO estimates:

•

•
•

HIV has claimed more than 36 million lives, including 680,000 in 2020. Approximately 37.7 million people were living with HIV at the end of
2020, and 1.5 million were newly infected during 2020.
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  in  the  United  States  and  a  number  of  international
markets, including Brazil, Europe, Africa, Malaysia and Mexico. We are pursuing a CLIA waiver for the DPP HIV-Syphilis test in the United States.

We also market and sell tests for selected fever and tropical diseases such as Chagas, ebola, leishmaniasis and Zika. The market for lateral flow mosquito-
borne diseases includes established markets for disease such as  dengue  and  malaria,  which  WHO  estimates  together  account  for  more  than  600  million
annual  infections  worldwide.  There  are  also  a  number  of  emerging  markets  for  rapid  point  of  care  tests  for  infectious  diseases  such  as  burkholderia,
chikungunya, lassa, leptospirosis, Marburg, rickettsia and Zika.

Since  2015  we  have  received  over  $25.1  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,  The  Oswaldo  Cruz  Foundation  or  FIOCRUZ,  and  the  Foundation  for  Innovative  New  Diagnostics,  or  FIND,  as  well  as  U.S.  government
agencies  such  as  Centers  for  Disease  Control  and  Prevention,  or  CDC,  the  Biomedical  Advanced  Research  and  Development  Authority  of  the  U.S.
Department of Health and Human Services, or BARDA, and the U.S. Department of Agriculture, or USDA.

Several tests in our infectious disease pipeline are approaching commercialization, and several have received initial regulatory approvals:

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. During
2021, we expanded our U.S.-based sales, customer service, and marketing team to focus on the COVID-19, HIV-Syphilis, and future DPP platform product
opportunities. With sales growth as an underlying objective, we are focused on increasing sales in geographies that support higher average selling prices.
From  lead  generation  through  technical  inquiries,  Chembio  has  the  internal  resources  to  support  customers  through  the  commercial  process  including
marketing, sales, sales support, order entry and product support.

Automation of U.S. Manufacturing

We are automating our U.S. manufacturing processes and expanding our manufacturing capacity. Over the past three years, we have taken delivery of and
completed validation of most of our automated manufacturing lines. These use vision-guided, robotic operation to improve inspection and quality control.
As we transition from manual to automated assembly, we believe the reduced variable costs will improve product gross margins.

DPP Technology & Development

Our  commercially  available  products  employ  either  our  patented  DPP  technology  or  traditional  lateral  flow  technology.  We  believe  products  developed
using our DPP technology can provide superior diagnostic performance compared with products that utilize traditional lateral flow technology.

Chembio’s history of collaborations have proven the strength and capabilities of the DPP platform to address a diverse range of biomarkers. We are now
focusing our R&D resources on delivering products to build a portfolio of COVID-19 tests and developing Chembio’s new and expanded product portfolio
focused on high average selling price, developed markets, established sales channels, and clinically accepted use cases, where the differentiated capabilities
of DPP provide a competitive advantage.

Competition

Many  of  our  competitors  are  significantly  larger  and  have  greater  financial,  research,  manufacturing,  and  marketing  resources.  Important  competitive
factors include product quality, analytical performance, ease of use, price, customer service and reputation. Industry competition is based on these and the
following additional factors:

•
•
•
•
•
•
•

patent protection;
scientific expertise;
ability to develop and market products and processes;
ability to obtain required regulatory approvals;
ability to manufacture cost-effective products that meet applicable regulatory requirements;
access to adequate capital; and,
ability to attract and retain qualified personnel.

We  believe  our  scientific  capabilities  and  proprietary  know-how  relating  to  our  patented  DPP  technology  and  lateral  flow  technology  are  very  strong,
particularly for the development and manufacture of tests for the detection of  infectious and other diseases.

Table of Contents

Although we have no specific knowledge of any other competitors’ products that could render our products obsolete, if we fail to maintain and enhance our
competitive position or fail to introduce new products and product features, our customers may decide to use the products developed by our competitors,
which could result in a loss of revenues and cash flow.

Human Capital

As of December 31, 2021, we had 337 full-time equivalent employees, of whom 46 were in administration, 241 were in manufacturing, 28 were in research
and development, and 22 were in sales and marketing and customer service. Of these employees, approximately 297 were located in the United States, 22
were  located  in  Germany  and  18  were  located  in  Brazil.  We  have  never  had  a  work  stoppage,  and  none  of  our  employees  are  represented  by  a  labor
organization or subject to any collective bargaining arrangements. We consider our employee relations to be good.

Our employees are one of our most important assets and set the foundation for our ability to achieve our strategic objectives, drive operational execution,
deliver  strong  financial  performance,  advance  innovation  and  maintain  our  quality  and  compliance  programs.  The  success  and  growth  of  our  business
depends  in  large  part  on  our  ability  to  attract,  retain  and  develop  a  diverse  population  of  talented  and  high-performing  employees  at  all  levels  of  our
organization.

Health, Wellness and Safety

The health, wellness and safety of our employees is a priority embedded at every level of our business.  We provide our employees upfront and ongoing
safety training to ensure that safety policies and procedures are effectively communicated and implemented.  Personal protective equipment is provided to
those employees where needed for the employee to safely perform their job function.

Since  2020,  in  response  to  the  COVID-19  pandemic,  we  implemented  safety  protocols  and  new  procedures  to  protect  our  employees,  including  more
frequent deep cleaning of the facilities, social distancing and onsite COVID-19 testing.

Workforce Stability

Retaining and developing our employees is an important factor in our continued success and growth. We regularly evaluate our employee retention and
turnover rates. With the contraction of the labor force as a result of the global pandemic, we have also experienced the effects of the labor shortage in our
staffing. We expect the labor shortage to continue in 2022 and will continue to monitor and analyze retention closely to identify any areas of concern.

Compensation and Benefits

To succeed in a competitive labor market, we have recruitment and retention strategies that we focus on as part of the overall management of our business,
including designing our compensation and benefits programs to be competitive and align with our strategic and stockholders’ interests. Some of our key
employee benefits include eligibility for health insurance, vacation time, a retirement plan, an employee assistance program, life and disability coverage.
We  also  have  procedures  and  processes  focused  on  providing  employees  equitable  compensation,  regardless  of  race  or  gender  or  other  personal
characteristics.

Impact of the COVID-19 Pandemic

The COVID-19 pandemic has disrupted nearly every aspect of the global supply chain, including the manufacturing of some of the key supplies used in our
tests. Many suppliers are experiencing shortages of required personnel as the result of the tight labor market and underlying raw material commodities. To
fulfil our obligations, we have had to identify sources of supplies on a short timeframe and in a markedly increased quantity and have been required to seek
to identify new sources of materials to replace or augment our past sources. Moreover, scarcity has caused increases in the cost of some supplies.

Governmental Regulation

Certain  of  our  activities  are  subject  to  regulatory  oversight  by  the  FDA  under  provisions  of  the  Federal  Food,  Drug,  and  Cosmetic  Act  and  regulations
thereunder,  including  regulations  governing  the  development,  marketing,  labeling,  promotion,  manufacturing,  and  export  of  diagnostic  products.  Our
clinical laboratory customers are subject to oversight by Centers for Medicare and Medicaid Services, or CMS, pursuant to CLIA, as well as agencies in
various states. Failure to comply with applicable requirements can lead to sanctions, including withdrawal of products from the market, recalls, refusal to
authorize government contracts, product seizures, civil money penalties, injunctions, and criminal prosecution.

FDA Approval/Clearance Requirements

Unless  an  exemption  applies,  each  medical  device  that  we  market  or  wish  to  market  in  the  United  States  must  receive  510(k)  clearance  or  Premarket
Approval, or PMA. Medical devices that receive 510(k) clearance are “cleared” by the FDA to market, distribute, and sell in the United States. Medical
devices that obtain a PMA by the FDA are “approved” to market, distribute and sell in the United States. We cannot be certain that 510(k) clearance or
PMA approval will  ever  be  obtained  for  any  products  that  have  not  already  obtained  510(k)  clearance  or  PMA  approval.  Descriptions  of  the  PMA  and
510(k) clearance processes are provided below.

The FDA decides whether a device line must undergo either the 510(k) clearance or PMA based on statutory criteria that utilize a risk-based classification
system. PMA is the FDA process of scientific and regulatory review to evaluate the safety and effectiveness of Class III medical devices and, in many
cases, Class II medical devices. Class III devices are those that support or sustain human life, are of substantial importance in preventing impairment of
human health, or which present a potential, unreasonable risk of illness or injury. The FDA uses these criteria to decide whether a PMA or a 510(k) is
appropriate, including the level of risk that the agency perceives is associated with the device and a determination by the agency of whether the product is a
type of device that is similar to devices that are already legally marketed. Devices deemed to pose relatively less risk are placed in either Class I or II. In
many cases, the FDA requires the manufacturer to submit a 510(k) requesting clearance (also referred to as a premarket notification), unless an exemption
applies. The 510(k) must demonstrate that the manufacturer’s proposed device is “substantially equivalent” in intended use and in safety and effectiveness
to a legally marketed predicate device. A “predicate device” is a pre-existing medical device to which equivalence can be drawn, that is either in Class I or
Class II or is a Class III device that was in commercial distribution before May 28, 1976, for which the FDA has not yet called for submission of a PMA
application.

Device classification depends on the device’s intended use and its indications for use. In addition, classification is risk-based, that is, the risk the device
poses to the patient and/or the user is a major factor in determining the class to which it is assigned. Class I includes devices with the lowest risk and Class
III includes those with the greatest risk.

Class I devices are those for which safety and effectiveness can be assured by adherence to the FDA’s general regulatory controls for medical devices, or
the  General  Controls,  which  include  compliance  with  the  applicable  portions  of  the  FDA’s  quality  system  regulations,  facility  registration  and  product
listing, reporting of adverse medical events, and appropriate, truthful and non-misleading labeling, advertising, and promotional materials. Some Class I
devices also require premarket clearance by the FDA through the 510(k) process described below.

Class II  devices  are  subject  to  the  FDA’s  General  Controls,  and  any  other  special  controls  as  deemed  necessary  by  the  FDA  to  ensure  the  safety  and
effectiveness of the device. Premarket review and clearance by the FDA for Class II devices is accomplished through the 510(k) process. Pursuant to the
Medical Device User Fee and Modernization Act of 2002, unless a specific exemption applies, 510(k) submissions are subject to user fees. Certain Class II
devices are exempt from this premarket review process.

Class III includes devices with the greatest risk. Devices in this class must meet all of the requirements in Classes I and II. In addition, Class III devices
cannot be marketed until they receive Premarket Approval.

The  safety  and  effectiveness  of  Class  III  devices  cannot  be  assured  solely  by  the  General  Controls  and  the  other  requirements  described  above.  These
devices require formal clinical studies to demonstrate safety and effectiveness. Under the Medical Device User Fee and Modernization Act of 2002, PMA
applications (and supplemental premarket approval applications) are subject to significantly higher user fees than 510(k) applications, and they also require
considerably more time and resources.

Rapid HIV tests intended for diagnostic use are regulated as Class III devices. Responsibility for assuring the safety and effectiveness of these tests lies
within  the  Center  for  Biologics  Evaluation  and  Research’s  Office  of  Blood  Research  and  Review,  with  oversight  by  the  Blood  Products  Advisory
Committee. Approved rapid HIV tests must meet the regulations in the 21 CFR 800 series subparts, under the investigational device exemption, or IDE and
PMA pathways.

Premarket Approval Pathway

We manufacture, market and distribute three rapid HIV tests in the United States. Our HIV 1/2 STAT-PAK Assay, SURE CHECK HIV 1/2 Assay, and DPP
HIV 1/2 Assay all have received FDA PMA approval. A PMA application must be supported by extensive data including, but not limited to, analytical,
preclinical,  clinical  trials,  manufacturing,  statutory  preapproval  inspections,  and  labeling  to  demonstrate  to  the  FDA’s  satisfaction  the  safety  and
effectiveness of the device for its intended use. Before a PMA is submitted, a manufacturer must apply for an Investigational Device Exemption (“IDE”). If
the device presents a “significant risk,” as defined by the FDA, to human health, the FDA requires the device sponsor to file an IDE application with the
FDA  and  obtain  IDE  approval  prior  to  initiation  of  enrollment  of  human  subjects  for  clinical  trials.  The  IDE  provides  the  manufacturer  with  a  legal
pathway to perform clinical trials on human subjects where without the IDE, only approved medical devices may be used on human subjects.

The IDE application must be supported by appropriate data, such as analytical, animal and laboratory testing results, manufacturing information, and an
Investigational Review Board, or IRB approved protocol showing that it is safe to test the device in humans and that the testing protocol is scientifically
sound. If the clinical trial design is deemed to have “non-significant risk,” the clinical trial may be eligible for “abbreviated” IDE requirements. In some
instances,  clinical  trials  for  in  vitro  diagnostic  medical  devices  may  be  exempt  from  the  more  burdensome  IDE  requirements  if  certain  labeling
requirements are met.

A clinical trial may be suspended by either the FDA or the Investigational Review Board at any time for various reasons, including a belief that the risks to
the  study  participants  outweigh  the  benefits  of  participation  in  the  study.  Even  if  a  study  is  completed,  clinical  testing  results  may  not  demonstrate  the
safety and efficacy of the device, or they may be equivocal or otherwise insufficient to obtain approval of the product being tested. After the clinical trials
have been completed, if at all, and the clinical trial data and results are collected and organized, a manufacturer may complete a PMA application.

After  a  PMA  application  is  sufficiently  complete,  the  FDA  will  accept  the  application  and  begin  an  in-depth  review  of  the  submitted  information.  By
statute, the FDA has 180 days to review the “accepted application,” although, generally, review of the application can take between one and three years, but
it may take significantly longer. During this review period, the FDA may request additional information or clarification of information already provided.
Also, during the review period, an advisory panel of experts from outside the FDA may be convened to review and evaluate the application and provide
recommendations  to  the  FDA  as  to  the  approvability  of  the  device.  The  preapproval  inspections  conducted  by  the  FDA  include  an  evaluation  of  the
manufacturing  facility  to  ensure  compliance  with  the  FDA’s  quality  systems  regulations  or  QSR,  as  well  as  inspections  of  the  clinical  trial  sites  by  the
Bioresearch  Monitoring  group  to  evaluate  compliance  with  good  clinical  practice  and  human  subject  protections.  New  PMA  applications  or  PMA
supplements are required for modifications that affect the safety or effectiveness of the device, including, for example, certain types of modifications to the
device’s indication for use, manufacturing process, labeling and design. Significant changes to an approved PMA require a 180-day supplement, whereas
less substantive changes may utilize a 30-day notice, or a 135-day supplement. Premarket approval supplements often require submission of the same type
of information as a premarket approval application, except that the supplement is limited to information needed to support any changes from the device
covered by the original premarket approval application, and it may not require as extensive clinical data or the convening of an advisory panel.

Our HIV 1/2 STAT-PAK Assay PMA application number BP050009/0 and our SURE CHECK 1/2 HIV Assay PMA application number BP050010/0 were
approved by the FDA in May 2006. Our DPP HIV 1/2 Assay PMA application number BP120032/0 was approved by the FDA in December 2012.  Our
DPP HIV Syphilis Assay PMA application number BP180191/0 was approved by the FDA in October 2020.

510(k) Clearance Pathway

We are currently developing products that either will or are likely to require an FDA 510(k) clearance. We anticipate submitting a 510(k) for each such
product  to  demonstrate  that  such  proposed  device  is  substantially  equivalent  to  a  previously  cleared  510(k)  device  or  a  device  that  was  in  commercial
distribution before May 28, 1976, for which the FDA has not yet called for the submission of a 510(k).  The FDA’s 510(k) clearance pathway usually takes
from  three  to  twelve  months  but  could  take  longer.  In  some  cases  the  FDA  may  require  additional  information,  including  clinical  data,  to  make  a
determination regarding substantial equivalence.

If a device receives 510(k) clearance, any modification that could significantly affect its safety or effectiveness, or that would constitute a new or major
change in its intended use, will require a new 510(k) clearance or, depending on the modification, a PMA. The FDA requires each device manufacturer to
determine whether the proposed change requires submission of a new 510(k) or a PMA, but the FDA can review any such decision and, if it disagrees with
the manufacturer’s determination, can require the manufacturer to cease marketing and/or recall the modified device until 510(k) clearance or PMA of the
modified device is obtained.

Clinical Laboratory Improvement Amendments of 1988

A manufacturer of a test categorized as moderately complex may request that categorization of the test be waived through a CLIA Waiver by Application,
or  CW,  submission  to  the  FDA.  When  a  test  is  categorized  as  waived,  it  may  be  performed  by  laboratories  with  a  Certificate  of  Waiver,  such  as  a
physician’s office outreach setting. In a CW submission, the manufacturer provides evidence to the FDA that a test meets the CLIA statutory criteria for
waiver CLIA, a walk-in clinic or an emergency room provides CMS authority over all laboratory testing, except research that is performed on humans in
the United States. The Division of Laboratory Services, within the Survey and Certification Group under the CMS, has the responsibility for implementing
the CLIA program.

The  CLIA  program  is  designed  to  establish  quality  laboratory  testing  by  ensuring  the  accuracy,  reliability  and  timeliness  of  patient  test  results.  Under
CLIA,  a  laboratory  is  a  facility  that  does  laboratory  testing  on  specimens  derived  from  humans  and  used  to  provide  information  for  the  diagnosis,
prevention or treatment of disease, or impairment of, or assessment of health. Under the CLIA program, unless waived, laboratories must be certified by the
government, satisfy governmental quality and personnel standards, undergo proficiency testing, be subject to inspections and pay fees. We have received a
CLIA waiver for all of our lateral flow rapid HIV tests that we market in the United States. Specifically, the CLIA waiver was granted by the FDA for HIV
1/2 STAT-PAK in November 2006, for SURE CHECK HIV 1/2 in October 2007, and for DPP HIV 1/2 in October 2014.

Emergency Use Authorizations (EUA)

A formal request to issue an EUA generally should not be submitted until the Secretary of HHS has issued an EUA declaration under section 564(b)(1). In
particular,  although  section  564  allows  FDA  to  issue  an  EUA  for  preparedness  purposes,  in  such  cases  the  HHS  Secretary  must  first  declare  that
circumstances  exist  justifying  such  an  authorization  in  advance  of  an  actual  emergency  based  on  a  formal  determination  of  a  significant  potential  for
emergency or a material threat determination. During the effective period of the HHS Secretary’s EUA declaration, FDA may authorize the introduction of
a medical product into interstate commerce when the product is intended for use during an actual or potential emergency. EUA candidate products include
medical products and uses that are not approved, cleared, or licensed under sections 505, 510(k), and 515 of the FD&C Act or section 351 of the PHS Act.

After the requisite determination and declaration have been issued, and after feasible and appropriate consultations, FDA may issue an EUA only if FDA
concludes that the following four statutory criteria for issuance have  been  met  for  1)  Serious  or  Life-Threatening  Disease  or  conditions,  2)  evidence  of
effectiveness, 2) Risk –Benefit Analysis, 4) No Alternatives.  A sponsor seeking an EUA can submit its formal request in the form of an EUA submission,
which includes data for clinical studies, non-clinical laboratory studies to assess the safety and effectiveness of the product as well as the discussion of
Risks and Benefits of the product.

FDA will specify the effective date of an EUA issued under section 564. In general, an EUA will remain in effect for the duration of the EUA declaration
under which it was issued which describes termination of an EUA declaration and its impact on existing EUAs.

Pervasive and Continuing FDA Regulation

A host of regulatory requirements apply to our approved devices, including: the quality system regulation, which requires manufacturers to follow elaborate
design, testing, control, documentation and other quality assurance procedures; the Medical Reporting Regulations, which require manufacturers to report
to the FDA specified types of adverse events involving their products; labeling regulations; and the FDA’s general prohibition against promoting products
for unapproved or “off-label” uses. Some Class II devices are subject to special controls-such as performance standards, post-market surveillance, patient
registries, and FDA guidelines-that do not apply to Class I devices.

The regulatory requirements that apply to our approved products classified as medical devices include:

•
•

•
•

product listing and establishment registration, which helps facilitate FDA inspections and other regulatory action;
QSR, which require manufacturers, including third-party manufacturers, to follow stringent design, testing, control, documentation and other
quality assurance procedures during all aspects of the development and manufacturing process;
labeling regulations and FDA prohibitions against the promotion of products for uncleared, unapproved or off-label use or indication;
clearance of product modifications that could significantly affect safety or efficacy or that would constitute a major change in intended use of one
of our cleared devices;
approval of product modifications that affect the safety or effectiveness of one of our cleared devices;

•
• medical device reporting regulations, which require that manufacturers comply with FDA requirements to report if their device may have caused

or contributed to a death or serious injury, or has malfunctioned in a way that would likely cause or contribute to a death or serious injury if the
malfunction of the device or a similar device were to recur;
post-approval restrictions or conditions, including post-approval study commitments;
post-market surveillance regulations, which apply when necessary to protect the public health or to provide additional safety and effectiveness
data for the device;
the FDA’s recall authority, whereby it can ask, or under certain conditions order, device manufacturers to recall from the market a product that is in
violation of governing laws and regulations;
regulations pertaining to voluntary recalls; and,
notices of corrections or removals.

Our Medford, New York facility is currently registered as an establishment with the FDA. We and any third-party manufacturers are subject to announced
and unannounced inspections by the FDA to determine our compliance with QSR and other regulations.

Government Regulation of Medical Devices for Animal Subjects

We currently offer two veterinary devices in the United States: DPP VetTB Assay for Cervids and DPP VetTB Assay for Elephants. Diagnostic tests for
animal health infectious diseases, including our veterinary devices for the prevention and/or treatment of animal disease, are regulated in the U.S. by the
Center for Veterinary Biologics within the U.S. Department of Agriculture Animal and Plant Health Inspection Service, or APHIS, under the Virus, Serum,
and Toxin Act of 1913. As a requirement, our veterinary devices were approved by APHIS before they could be sold in the U.S.

16

 
 
 
 
 
 
 
 
 
 
 
Table of Contents

The  APHIS  regulatory  approval  process  involves  the  submission  of  product  performance  data  and  manufacturing  documentation.  Following  regulatory
approval to market a product, APHIS requires that each lot of product be submitted for review before release to customers. In addition, APHIS requires
special approval to market products where test results are used in part for government-mandated disease management programs.

Climate Change and Environmental Laws

The  medical  device  industry  is  increasingly  becoming  subject  of  scrutiny,  stringent  regulation  and  the  demand  for  green,  sustainable  products.  We  are
focused  on  monitoring  these  increasing  requirements  for  efficient  and  accurate  processes  for  hazardous  substance  handling,  supplier  disclosures,  and
regulatory reporting in order to comply with numerous global health and environmental regulatory requirements and restrictions.

We  believe  that  we  are  in  compliance  in  all  material  respects  with  all  foreign,  federal,  state,  and  local  environmental  regulations  applicable  to  our
manufacturing facilities. The cost of ongoing compliance with such regulations does not have a material effect on our operations.

Intellectual Property

Intellectual Property Strategy

Our  intellectual  property  strategy  is  to:    (1)  build  our  own  intellectual  property  portfolio  around  our  DPP  technology  and  optical  analyzers;  (2)  pursue
licenses, trade secrets and know-how within the area of rapid point-of-care testing; and, (3) develop and acquire proprietary positions to certain reagents.

DPP Intellectual Property

We have obtained patent coverage on our DPP technology, including numerous patents in the United States, and one or more patents in Australia, Brazil,
Canada, China, Columbia, Eurasia (Russia), European Union (fourteen European countries), Hong Kong, Israel, India, Indonesia, Japan, Korea, Malaysia,
Mexico, Poland, Singapore, South Africa, Thailand, and the United Kingdom. Additional patent applications on our DPP technology are pending in the
United States, as well as in  foreign countries such as Australia, Brazil, Canada, China, the European Union, India, Indonesia, Malaysia, Mexico, Peru,
Singapore and Thailand.

DPP technology provides us with freedom to operate and enables us to develop tests with better performance and capabilities compared with tests built on
traditional lateral flow platforms.  These advantages have allowed us to enter into multiple technology collaborations based upon DPP technology, which
we believe will provide new manufacturing and marketing opportunities. We have filed additional patent applications that we believe will strengthen the
DPP intellectual property and have also filed for patent protection for certain other point-of-care technologies or applications thereof.

We have also obtained patent coverage on our optical-based analyzer technology in the United States as well as in several EU countries.

Trademarks

We have filed and obtained trademarks for our company name CHEMBIO and CHEMBIO DIAGNOSTIC SYSTEMS, INC. as well as for many of our
products,  including  DPP,  SURE  CHECK,  STAT-VIEW,  STAT-PAK,  and  NEXT  GENERATION  DPP,  as  well  as  for  the  SampleTainer  and  DPP  Micro
Reader, which are used with certain DPP products.  Our trademarks have been registered in the United States and certain other countries around the world.

Trade Secrets and Know-How

We  have  developed  a  substantial  body  of  trade  secrets  and  know-how  relating  to  the  development  and  manufacture  of  lateral  flow  and  DPP-based
diagnostic  tests,  including  the  sourcing  and  optimization  of  materials  for  such  tests,  and  methods  to  maximize  sensitivity,  speed-to-result,  specificity,
stability  and  reproducibility  of  our  tests.    We  possess  proprietary  know-how  to  develop  tests  for  multiple  conditions  using  colored  particles.    Our
formulations enable long shelf lives of our rapid HIV and other tests, providing us with an important competitive advantage.

Rapid Diagnostic Technology and Reagent Licenses

We seek licenses and/or redesigns of products that we believe to be in our best interests. Because of the costs and other negative consequences of time
consuming patent litigation, we often attempt to obtain a license on reasonable terms. The peptides used in our rapid HIV tests were licensed to us by one
or more third parties. We also have licensed the antigens used in other tests including our Syphilis, Tuberculosis, Leptospirosis, Leishmaniasis and Chagas
tests, and we may enter into other license agreements. In prior years, we concluded license agreements related to intellectual property rights owned by the

RISK FACTORS

Risks Related to Our Business and Our Industry

Our near term success is highly dependent on the success of the our DPP platform, and we cannot be certain that we will succeed in developing one or
more of those systems or that, if we do, they will attain market acceptance or be successfully commercialized in the United States or elsewhere.

We do not currently have an Emergency Use Authorization, or EUA, from the U.S. Food and Drug Administration, or FDA, for any of the COVID-19
Diagnostic Test Systems or for our DPP Respiratory Panel, and we do not currently have an application pending for any such EUA. We also do not have a
CLIA waiver from the FDA for our DPP HIV-Syphilis test system. Market and regulatory requirements continue to change at a rapid pace. The FDA has
declined to review our most recent EUAs submitted for our DPP SARS-CoV-2 Antigen System based on then-effective prioritization guidance, which is
subject to change. There can be no assurance that, if we make a submission of any future EUA or CLIA waiver application, we will meet the requirements
of the prioritization guidance in effect at the time of the submission or otherwise be successful in obtaining either (1) an EUA that would permit us to offer
and sell the DPP SARS-CoV-2 Antigen test system or DPP Respiratory Panel in the United States or (2) a CLIA waiver for our DPP HIV-Syphilis test.

21

 
 
 
 
 
 
 
 
 
Table of Contents

Even if we are able to obtain any such EUA or CLIA waiver, our product may not gain broad market acceptance among physicians, healthcare payers,
patients, and the medical community. We cannot guarantee market acceptance of our product, and have somewhat limited information on which to estimate
our anticipated level of sales. Our products will require healthcare providers and doctors to accept and adopt our technology. Our industry is susceptible to
rapid technological developments and there can be no assurance that we will be able to match any new technological advances. Acceptance and use of any
products we market will depend upon a number of factors including:

•
•
•
•
•
•
•
•

perceptions by members of the health care community, including physicians, about the safety and effectiveness of our products;
limitation on use or warnings required by the FDA or other global regulators in our product labeling;
the cost of our products relative to competing products;
convenience and ease of administration;
potential advantages of alternative diagnostic and treatment methods;
availability of reimbursement for our products from government or other healthcare payers;
effectiveness of marketing and distribution efforts by us and our licensees and distributors, if any; and
the ability of our diagnostic solutions to address different variants.

In addition, with respect to any EUA we obtain, the FDA may revoke an EUA where it is determined that the underlying health emergency no longer exists
or warrants such authorization, even if we obtain an EUA, we cannot predict how long such EUA would remain in place. Such revocation could materially
adversely impact our business in a variety of ways, including if the relevant product is not yet approved by the FDA under a traditional approval pathway
and if we have invested in the supply chain to provide any of our products under an EUA, and would require us to obtain a 510(k) or other marketing
authorization  from  the  FDA.  If  the  FDA  revokes  a  previously  issued  EUA  prior  to  us  having  received  regulatory  approval  to  commercialize  our  DPP
SARS-CoV-2 Antigen test system or DPP Respiratory Panel through a traditional approval pathway, we would be required to cease our commercialization
efforts, which would substantially and negatively impact our business.

The failure of these products to find market acceptance would substantially harm our business and would adversely affect our revenue. If the DPP SARS-
CoV-2 Antigen test system, DPP Respiratory Panel or DPP  HIV-Syphilis test are not as successfully commercialized as expected, we may not be able to
generate sufficient revenue to become profitable. Any failure of one of these products to be successfully commercialized in the United States may have a
material adverse effect on our business, operating result financial condition and cash flows, and could result in a substantial decline in the price of our
common stock. In addition, the production and widely administered use of efficacious vaccines for COVID-19 may reduce the demand for diagnostic tests
and,  as  a  result,  the  COVID-19  diagnostic  testing  market  may  not  develop  or  substantially  grow.  Our  future  success  is  substantially  dependent  on  the
manner in which the market for diagnostic testing develops and grows. If the market develops in a manner that does not facilitate demand for our products,
or  fails  to  develop  or  grow  in  the  manner  in  which  we  expect  or  at  all,  our  business,  financial  condition,  results  of  operations  and  cash  flows  may  be
negatively affected.

Clinical trials necessary to support a future test kit submission will be expensive and may require the enrollment of large numbers of subjects, and suitable
subjects may be difficult to identify and recruit. Delays or failures in our clinical trials will prevent us from commercializing any modified or new test kits
and will adversely affect our business, operating results and prospects.

22

 
 
 
 
 
 
 
 
Table of Contents

Initiating and completing clinical trials necessary to support a future EUA, 510(k), PMA, or de novo submission, will be time consuming, expensive,
and have an uncertain outcome. Moreover, the results of early clinical trials are not necessarily predictive of future results, and any test kit we advance
into clinical trials may not have favorable results in later clinical trials.

Conducting successful clinical trials will require the enrollment of large numbers of subjects, and suitable subjects may be difficult to identify and recruit.
Subject  enrollment  in  clinical  trials  and  completion  of  subject  participation  depends  on  many  factors,  including  the  nature  of  the  trial  protocol,  the
attractiveness  of,  or  the  discomforts  and  risks  associated  with,  the  indication  of  the  underlying  test  kit,  the  availability  of  appropriate  clinical  trial
investigators, support staff, and proximity of subjects to clinical sites and able to comply with the eligibility and exclusion criteria for participation in the
clinical trial and subject compliance. In addition, subjects may not participate in our clinical trials if they choose to participate in contemporaneous clinical
trials of competitive products.

In  addition,  our  clinical  trials  may  in  the  future  be  affected  by  the  COVID-19  pandemic.  For  example,  subjects  may  choose  not  to  enroll  or  continue
participating in the clinical trial as a result of the pandemic. As a result, potential subjects in our clinical trials may choose to not enroll, not participate in
follow-up clinical visits, or drop out of the trial as a precaution against contracting COVID-19. Further, some subjects may not be able or willing to comply
with clinical trial protocols if quarantines impede subject movement or interrupt healthcare services. We are unable to predict with confidence the duration
of  any  such  potential  subject  enrollment  delays  and  difficulties,  whether  related  to  COVID-19  or  otherwise.  Delays  in  subject  enrollment  or  failure  of
subjects to continue to participate in a clinical trial may cause an increase in costs and delays in the approval and attempted commercialization of our test
kits or result in the failure of the clinical trial.

Development  of  sufficient  and  appropriate  clinical  protocols  to  demonstrate  safety  and  efficacy  are  required  and  we  may  not  adequately  develop  such
protocols to support clearance and approval. Further, the FDA may require us to submit data on a greater number of subjects than we originally anticipated
and/or  for  a  longer  follow-up  period  or  change  the  data  collection  requirements  or  data  analysis  applicable  to  our  clinical  trials.  In  addition,  despite
considerable time and expense invested in our clinical trials, the FDA may not consider our data adequate for approval. Such increased costs and delays or
failures could adversely affect our business, operating results and prospects.

We have been allocating a substantial portion of our resources to the development and commercialization of DPP SARS-CoV-2 Antigen test system,
and our long term business success could be negatively impacted by our diversion of resources from our legacy business of diagnostic testing for other
infectious diseases.

In  the  first  quarter  of  2020  we  began  committing  substantially  all  of  our  financial  and  personnel  resources  to  the  development,  manufacturing  and
commercialization of the DPP SARS-CoV-2 Antigen test system. Because we  do  not  currently  have  an  EUA  from  the  FDA  for  the  DPP  SARS-CoV-2
Antigen test system, starting in the first quarter of 2021 we began allocating an increased portion of our resources to our legacy products. Our earlier and
continuing resource allocation to the DPP SARS-CoV-2 Antigen test system may have negatively impacted, and may continue to negatively impact, our
legacy product portfolio, as we have spent limited funds and time on updating pre-existing products and regulatory approvals and on completing products
that were in development prior to our strategic decision to focus on the DPP SARS-CoV-2 Antigen test system. Our business could be negatively impacted
by our allocation of significant resources to a global health threat that is unpredictable and could dissipate; there is no guarantee that current or anticipated
demand will continue, or if demand does continue, that we will be able to produce in quantities to meet the demand. We intend to continue to reestablish
our legacy business, but there can be no assurance that we will be able to successfully recommence the development and commercialization of our legacy
products and products under development.

The diagnostic testing market, particularly with respect to COVID‑19, is highly competitive, and many of our competitors are larger, better established
and have greater technical and marketing capabilities and financial and other resources than we have.

The diagnostics market, particularly with respect to COVID‑19 diagnostic tests, is highly competitive and we face substantial competition based on factors
such as product quality, analytical performance, ease of use, price, manufacturing costs, customer service and reputation. Industry competition is also based
the following additional factors:

● patent protection;
● scientific expertise;
● ability to develop and market products and processes;
● ability to obtain required regulatory approvals;
● ability to manufacture cost‑effective products that meet applicable regulatory requirements;
● access to adequate capital; and
● ability to attract and retain qualified personnel.

Table of Contents

Numerous  companies  in  the  United  States  and  internationally  have  introduced  or  announced  their  intention  to  introduce  new  products,  services  and
technologies that could be used in substitution for the DPP SARS-CoV-2 Antigen test system. Many of those competitors are significantly larger, and have
substantially greater financial, engineering and other resources, than us. In addition, our competitors may have or may develop products or technologies
that currently or in the future will enable them to produce competitive products with greater capabilities or at lower costs than ours. If we are unable to
compete effectively, we may fail to meet our strategic objectives, and our business, financial condition and operating results could be harmed. In addition,
the production of an efficacious vaccine or other treatment for a disease underlying one of our products may reduce the demand for relevant diagnostic
products. The success or failure, or perceived success or failure, of other companies may adversely impact our ability to obtain any future funding, or to
ultimately commercialize the DPP SARS-CoV-2 Antigen test system.

We face risks related to an ongoing SEC investigation.

The SEC is conducting a non-public, fact-finding investigation relating to the May 2020 Offering and to the FDA’s revocation in June 2020 of an EUA for
the  DPP  COVID-19  IgM/IgG  system  that  was  issued  in  April  2020.  We  received  subpoenas  from  the  SEC  in  July  2020  and  April  2021  seeking  the
production of documents in connection with this investigation. In addition, the SEC delivered subpoenas in April 2021 to five of our employees (including
our three executive officers, who consist of our Chief Executive Officer and President, our Executive Vice President and Chief Financial Officer, and our
Executive  Vice  President  and  Chief  Scientific  and  Technology  Officer).  An  additional  subpoena  was  issued  in  June  2021  to  our  former  Interim  Chief
Executive  Officer  and  Executive  Chair.  Each  subpoena  requested  the  production  of  documents  relating  to  the  same  matters  as  are  the  subject  of  the
subpoenas we received.

We are unable to predict what the timing or outcome of the SEC investigation will be or what, if any, consequences the SEC investigation may have with
respect to our company or the six individuals mentioned above. The SEC investigation could result in considerable legal expenses, divert management’s
attention from other business concerns and harm our business. If the SEC were to determine that legal violations occurred, we could be required to pay
significant civil penalties or other amounts, and remedies or conditions could be imposed as part of any resolution. We can provide no assurances as to the
outcome of the SEC investigation.

 Stockholder litigation could negatively impact our business, operating results and financial condition.

We may incur additional costs in connection with the defense or settlement of existing and any future stockholder litigation, including four stockholder
lawsuits to date that have been brought against us. See “Part I, Item 3. Legal Proceedings” below for additional information regarding existing lawsuits.
These lawsuits or other future litigation may adversely affect the ability of our technical and management personnel, and our directors, to perform their
normal responsibilities. We could incur significant costs in connection with any such litigation lawsuits, including costs associated with the indemnification
of obligations to our directors, officers and other employees, as well as to third parties such as underwriters of our public offerings.

We expect competition with respect to testing solutions for COVID-19 to continue to increase and our success will depend on market acceptance of our
products.

We expect competition to continue to increase as other established and emerging companies enter the market, as customer requirements evolve, and as new
products, services and technologies are introduced. The entrance of new competitors is being encouraged by governmental authorities, which are offering
funding to support development of testing solutions for COVID-19. Some of our existing or new competitors may have strong relationships with current
and potential customers, including governmental authorities that may help fund those competing entities through grant awards or other funding. As a result,
those  competitors  may  be  able  to  respond  more  quickly  to  new  or  changing  regulatory  requirements,  new  or  emerging  technologies,  and  changes  in
customer requirements. We do not currently have, or have an application pending for, an EUA from the FDA for any of the COVID-19 Diagnostic Test
Systems. Even if we succeed in obtaining approvals for commercialization for one or more of the COVID-19 Diagnostic Test Systems, those products may
not compete favorably, and we may not be successful in the face of existing and new products and technologies offered by our existing competitors or new
companies entering our markets. Any failure to compete effectively could materially and adversely affect our business, financial condition and operating
results.

24

The COVID‑19 pandemic could continue to affect our suppliers and employees, and cause disruptions in current and future plans for operations and
expansion.

The COVID‑19 pandemic may continue to directly and indirectly adversely impact our business, financial condition and operating results. The extent to
which this will continue will depend on numerous evolving factors that are highly uncertain, rapidly changing and cannot be predicted with precision or
certainty at this time.

Our business may continue to be disrupted due to the costs incurred as a result of additional necessary actions and preparedness plans to help ensure the
health and safety of our employees and continued operations, including enhanced cleaning processes, protocols designed to implement appropriate social
distancing practices, and/or adoption of additional wage and benefit programs to assist employees. We may also have difficulty meeting demand for our
products  if  our  employees  are  affected  by  COVID‑19,  or  if  we  do  not  have  adequate  space  to  produce  our  product  with  social  distancing  practices
implemented. We also cannot predict the effect of COVID‑19 pandemic on our supply chain’s reliability and costs.

In  addition,  our  business  and  operations,  and  the  operations  of  our  suppliers,  may  continue  to  be  adversely  affected  by  the  COVID‑19  pandemic.  The
pandemic,  including  the  related  response,  could  cause  disruptions  due  to  potential  suspension  or  slowdown  of  activities  at  our  third‑party  suppliers,
manufacturing delays, or increased prices implemented by our suppliers. The COVID-19 pandemic has disrupted nearly every aspect of the global supply
chain,  including  the  manufacturing  or  delivery  of  some  of  the  key  supplies  used  in  our  tests.  Many  suppliers  are  experiencing  shortages  of  required
personnel  as  the  result  of  the  tight  labor  market  and  underlying  raw  material  commodities.  Some  suppliers  have  been  unable  to  deliver  supplies  in  the
quantity we need or at all. As a result, these suppliers may stop supplying us components and materials, limit the allocation of supply and equipment to us
due to increased industry demand, or significantly increase their prices at any time with little or no advance notice. The adverse effect on our employees or
suppliers could have an adverse impact on our business, results of operations and financial condition.

We operate in a fragmented, segmented, and rapidly changing industry, which is highly competitive with respect to numerous factors, and our success
depends on our ability compete effectively with larger companies, develop new or enhance existing products, as well as acceptance of DPP over other
diagnostic platform technologies.

Important competitive factors for our products include price, quality, performance, ease of use, and customer service. A few large corporations produce a
wide variety of diagnostic tests and other medical devices and equipment. A larger number of mid‑size companies generally compete only in the diagnostic
industry and a significant number of small companies produce only a few diagnostic products. As a result, the diagnostic test industry is highly fragmented
and segmented.

More  generally,  the  point‑of‑care  diagnostics  industry  is  undergoing  rapid  technological  changes,  with  frequent  introductions  of  new  technology‑driven
products and services. As new technologies become introduced into the point‑of‑care diagnostic testing market, we may be required to commit considerable
additional efforts, time and resources to enhance our current product portfolio or develop new products. We may not have the available time and resources
to accomplish this, and many of our competitors have substantially greater financial and other resources to invest in technological improvements. We may
not  be  able  to  effectively  implement  new  technology‑driven  products  and  services  or  be  successful  in  marketing  these  products  and  services  to  our
customers, which would materially harm our operating results.

Although we own DPP patents, lateral flow technology is still a competitive platform to DPP, and lateral flow technology has a lower cost of manufacture
than  DPP  products.  Although  the  DPP  platform  has  shown  improved  sensitivity  as  compared  with  conventional  lateral  flow  platforms  in  a  number  of
studies, several factors go into the development and performance attributes of products. Therefore the ability of our products to successfully compete will
depend on several other factors, including our having a patented rapid test platform technology that differentiates DPP from lateral flow as well as from
other diagnostic platform technologies.

There can be no assurance that our DPP patents or our products incorporating those patents will not be challenged at some time in the future.

25

 
Table of Contents

Our competitors may develop and commercialize more effective or successful products, and our research, development and commercialization efforts
may not succeed.

We  regularly  commit  substantial  resources  to  research  and  development  and  the  commercialization  of  our  new  or  enhanced  products.  The  research  and
development process usually takes a long time from inception to commercial launch. During each stage of this process there is a substantial risk that we
will not achieve our goals in a timely fashion, or at all, and we may have to abandon a new or enhanced product in which we have invested substantial time
and money. We expect to continue to incur significant costs related to our research and development activities.

Our  products  require  significant  development  and  investment  prior  to  commercialization,  including  testing  to  demonstrate  the  products’  performance
capabilities, cost‑effectiveness or other benefits. We must obtain regulatory approval before most products may be sold and additional development efforts
on these products may be required before the products will be reviewed. However, regulatory authorities may not approve these products for commercial
sale or may substantially delay or condition such approval. There may be little or no market for the product and entry into or development of new markets
for our products may require an investment of substantial resources even if all applicable regulatory approvals are obtained. Furthermore, we may spend a
significant amount of money on advertising or other activities and still fail to develop a market for the product. The success of our efforts may be affected
by  our  ability  to  manufacture  products  in  a  cost‑effective  manner,  whether  we  can  obtain  necessary  intellectual  property  rights  and  protection  and  our
ability  to  obtain  reimbursement  authorizations  in  the  markets  where  the  product  will  be  sold.  Therefore,  if  we  fail  to  develop  and  gain  commercial
acceptance for our products, or if competitors develop more effective products or a greater number of successful new products, customers may decide not
to purchase our products.

Our products may not be able to compete with new diagnostic products or existing products developed by well‑established competitors, which would
negatively affect our business.

The  diagnostic  industry  is  focused  on  the  testing  of  biological  specimens  in  a  laboratory  or  at  the  point‑of‑care  and  is  highly  competitive  and  rapidly
changing. Important competitive factors for our products include price, quality, performance, ease of use, and customer service.

A  few  large  corporations  produce  a  wide  variety  of  diagnostic  tests  and  other  medical  devices  and  equipment.  A  larger  number  of  mid‑size  companies
generally compete only in the diagnostic industry and a significant number of small companies produce only a few diagnostic products. As a result, the
diagnostic test industry is highly fragmented and segmented.

Some  of  our  principal  competitors  may  have  considerably  greater  financial,  technical  and  marketing  resources  than  we  do.  Several  companies  produce
diagnostic tests that compete directly with our testing product line, including Abbott (Alere), OraSure Technologies and Trinity Biotech. Some competitors
offer broader product lines and may have greater name recognition than we have. These and other companies have or may have products incorporating
molecular or other advanced technologies that over time could directly compete with our testing product line. We also face competition from certain of our
distributors or former customers that have created or may decide to create, their own products to compete with ours.

As new products incorporating new technologies enter the market, our products may become obsolete or a competitor’s products may be more effective or
more effectively marketed and sold. If our competitors’ products take market share from our products through more effective marketing or competitive
pricing,  our  revenues,  margins  and  operating  results  could  be  adversely  affected.  In  addition,  our  revenues  and  operating  results  could  be  negatively
impacted if some of our customers internally develop or acquire their own sample collection devices and use those devices in place of our products in order
to reduce costs.

Our future revenues and operating results may be negatively affected by ongoing consolidation in the healthcare industry.

There  has  been  a  significant  amount  of  consolidation  in  the  healthcare  industry.  This  consolidation  has  increased  the  competition  to  provide  goods  and
services to customers. In addition, group purchasing organizations and integrated health delivery networks have served to concentrate purchasing decisions
for some customers, which has also placed pricing pressure on medical device suppliers. Due to ongoing consolidation, there could be additional pressure
on the prices of our products.

We may not successfully manage the transition associated with the appointment of a new chief financial officer, which could have an adverse impact on
us.

On October 18, 2021, we announced that Neil A. Goldman had notified the board of directors of his resignation as our Executive Vice President and Chief
Financial  Officer.  On  January  6,  2022,  we  announced  that  we  had  appointed  Lawrence  J.  Steenvoorden  as  our  Chief  Financial  Officer,  effective  as  of
January 5, 2022.

The effectiveness of our new Chief Financial Officer, and our senior leadership team generally, and any further transition as a result of these changes, could
have a significant impact on our results of operations. Management transition is often difficult and inherently causes some loss of institutional knowledge,
which could negatively affect our results of operations and financial condition. Our ability to execute our business strategies may be adversely affected by
the uncertainty associated with these transitions.

Our continued growth depends on retaining our current key employees and attracting additional qualified personnel, and we may not be able to do so.

Our success depends to a large extent upon the skills and experience of our executive officers, sales, marketing, operations and scientific staff. We may not
be able to attract or retain qualified employees due to the intense competition for qualified personnel among medical products businesses and academic and
other research institutions, as well as to geographic considerations, our ability to offer competitive compensation and benefits, and other reasons.

If we are not able to attract and retain the necessary qualified personnel to accomplish our business objectives, we may experience constraints that will
adversely affect our ability to effectively manufacture, sell and market our products to meet the demands of our customers and strategic partners in a timely
fashion, or to support internal research and development programs.

We have entered into employment contracts with our Chief Executive Officer, Richard Eberly, our Chief Science & Technology Officer, Javan Esfandiari,
and  our  Chief  Financial  Officer,  Lawrence  J.  Steenvoorden.  Due  to  the  specific  knowledge  and  experience  of  these  executives  regarding  the  industry,
technology and market generally and to our company specifically, the loss of the services of any one of these executives could have a material adverse
effect on us. We have not obtained a key man insurance policy on any officers other than Messrs. Eberly and Esfandiari.

Third‑party reimbursement policies and potential cost constraints could negatively affect our business.

The  potential  end‑users  of  our  products  include  hospitals,  physicians  and  other  healthcare  providers.  If  these  end‑users  do  not  receive  adequate
reimbursement  for  the  cost  of  our  products  from  their  patients’  healthcare  insurers  or  payors,  the  use  of  our  products  could  be  negatively  impacted.
Furthermore,  the  net  sales  of  our  products  could  also  be  adversely  affected  by  changes  in  reimbursement  policies  of  government  or  private  healthcare
payors.

Hospitals, physicians and other healthcare providers who purchase diagnostic products in the United States generally rely on third‑party payors, such as
private health insurance plans, Medicare and Medicaid, to reimburse all or part of the cost of the product. Due to the overall escalating cost of medical
products and services, especially in light of the COVID‑19 outbreak and its straining of healthcare systems across the globe, there is increased pressure on
the healthcare industry, both foreign and domestic, to reduce the cost of products and services. Given the efforts to control and reduce healthcare costs in
the United States, available levels of reimbursement may change for our existing products or products under development. Third‑party reimbursement and
coverage may not be available or adequate in either the United States or international markets, current reimbursement amounts may be decreased in the
future and future legislation, and regulation or reimbursement policies of third‑party payors, may reduce the demand for our products or our ability to sell
our products on a profitable basis.

To the extent that we are unable to collect our outstanding accounts receivable, our operating results could be materially harmed.

There may be circumstances and timing that require us to accept payment terms, including delayed payment terms, from distributors or customers, which, if
not satisfied, could cause financial losses.

27

Table of Contents

We generally accept payment terms which require us to ship product before the contract price has been paid fully, and there also are circumstances pursuant
to which we may accept further delayed payment terms pursuant to which we may continue to deliver product. To the extent that these circumstances result
in significant accounts receivables and those accounts receivables are not paid on a timely basis, or are not paid at all, especially if concentrated in one or
two customers, we could suffer financial losses.

We believe our success depends in part on the continued funding of, and our ability to participate in, large testing programs in the U.S. and worldwide,
the funding of which may be reduced or discontinued or otherwise be unavailable to us.

We believe it to be in our best interests to meaningfully participate in large testing programs. Moreover many of these programs are funded by governments
and other donors, and there can be no assurance that funding will not be reduced or completely discontinued. Participation in these programs also requires
alignment and engagement with the many other participants in these programs, including the World Health Organization, or WHO, the U.S. Centers for
Disease Control and Prevention, the U.S. Agency for International Development, foreign governments and their agencies, non‑governmental organizations,
and HIV service organizations. If we are unsuccessful in our efforts to participate in these programs, our operating results could be materially harmed.

Developing testing guidelines could negatively affect sales of our products.

Government agencies may issue diagnostic testing guidelines or recommendations, which can alter the usage of our HIV testing products. New laws or
guidelines, or changes to existing laws or guidelines, and the manner in which these new or changed laws and guidelines are interpreted and applied, could
impact  the  degree  to  which  our  testing  products  are  used.  These  developments  could  affect  the  frequency  of  testing,  the  number  of  people  tested  and
whether the testing products are used broadly for screening large populations or in a more limited capacity. These factors could in turn affect the level of
sales of our products and our results of operations.

Some of our programs are supported by government grant awards, and our inability to obtain additional grant awards in the future or to derive all of
the funding potentially available under those awards could delay our development and introduction of products.

We have received funding under grant award programs funded by governmental agencies such as BARDA. To fund a portion of our future research and
development programs, we may apply for additional grant funding from these or similar governmental agencies. Funding by these governmental agencies
may,  however,  be  significantly  reduced  or  eliminated  in  the  future  for  a  number  of  reasons.  For  example,  some  programs  are  subject  to  a  yearly
appropriations  process  in  Congress.  We  may  not  receive  full  funding  under  current  or  future  grants  because  of  budgeting  constraints  of  the  agency
administering the program or unsatisfactory progress on the study being funded.

In  addition,  some  or  all  of  the  funding  available  under  grant  awards  may  be  conditioned  upon  our  successfully  meeting  specified  milestones  or  other
conditions, and there can be no assurance that those milestones or conditions will be met. For example, in December 2020 we were awarded the Second
Grant  pursuant  to  a  contract  from  BARDA  that  included  funding  milestones  related  to  our  development  and  pursuit  of  an  EUA  for  a  DPP  Respiratory
Antigen Panel and our submission for 510(k) clearance from the FDA for the DPP SARS CoV 2 Antigen System.

There can be no assurance that we will receive any future grant awards from any government agencies or that, if a grant award is obtained, we will receive
the full amount potentially available under the grant award. Our inability to obtain future grant awards, or to earn the full amount available under those
awards, could delay the development of our product candidates and the introduction of new products.

We could be exposed to liability if we experience security breaches or other disruptions, which could harm our reputation and business.

We  may  be  subject  to  cyber‑attacks  whereby  computer  hackers  may  attempt  to  access  our  computer  systems  or  our  third-party  IT  service  providers’
systems and, if successful, misappropriate personal or confidential information. In addition, a contractor or other third party with whom we do business
may  attempt  to  circumvent  our  security  measures  or  obtain  such  information,  and  may  purposefully  or  inadvertently  cause  a  breach  involving  sensitive
information. We will continue to evaluate and implement additional protective measures to reduce the risk and detect cyber incidents, but cyber‑attacks are
becoming more sophisticated and frequent and the techniques used in such attacks change rapidly. Even though we take cyber‑security measures that are
continuously reviewed and updated, our information technology networks and infrastructure may still be vulnerable due to sophisticated attacks by hackers
or breaches.

Even  the  most  well  protected  IT  networks,  systems,  and  facilities  remain  potentially  vulnerable  because  the  techniques  used  in  security  breaches  are
continually evolving and generally are not recognized until launched against a target and, in fact, may not be detected. Any such compromise of our or our
third party’s IT service providers’ data security and access, public disclosure, or loss of personal or confidential business information, could result in legal
claims  proceedings,  liability  under  laws  to  protect,  privacy  of  personal  information,  and  regulatory  penalties,  disrupt  our  operations,  require  significant
management attention and resources to remedy any damages that result, damage our reputation and customers willingness to transact business with us, any
of which could adversely affect our business.

Our  ability  to  efficiently  operate  our  business  is  reliant  on  information  technology,  and  any  material  failure,  inadequacy,  interruption  or  security
breach of that technology could harm our business.

We rely heavily on complex information technology systems across our operations and on the internet, including for management of inventory, invoices,
purchase orders, shipping, interactions with our third‑party logistics providers, revenue and expense accounting, consumer call support, and various other
processes  and  transactions.  Our  ability  to  effectively  manage  our  business,  coordinate  the  production,  distribution  and  sale  of  our  products,  respond  to
customer  inquiries,  and  ensure  the  timely  and  accurate  recording  and  disclosure  of  financial  information  depends  significantly  on  the  reliability  and
capacity of these systems and the internet.

If any of the foregoing systems fails to operate effectively, problems with transitioning to upgraded or replacement systems, or disruptions in the operation
of the internet, could cause delays in product sales and reduced efficiency of our operations. Significant expenditures could be required to fix any such
problem.

If there is an increase in demand for our products, it could require us to expend considerable resources or harm our customer relationships if we are
unable to meet that demand.

If  there  are  significant  or  unexpected  increases  in  the  demand  for  our  products,  we  may  not  be  able  to  meet  that  demand  without  expending  additional
capital  resources.  This  would  increase  our  capital  costs,  which  could  negatively  affect  our  earnings  and  liquidity  in  the  short  term.  In  addition,  new
manufacturing equipment or facilities may require FDA, WHO, and other regulatory approvals before they can be used to manufacture our products. To the
extent we are unable to obtain or are delayed in obtaining such approvals, our ability to meet the demand for our products could be adversely affected.
Furthermore,  our  suppliers  may  be  unable  or  unwilling  to  expend  the  necessary  capital  resources  or  otherwise  expand  their  capacity,  which  could
negatively affect our business.

Our business could be negatively affected if we or our suppliers are unable to develop necessary manufacturing capabilities in a timely manner. If we fail to
increase production volumes in a cost effective manner or if we experience lower than anticipated yields or production problems as a result of changes that
we or our suppliers make in our manufacturing processes to meet increased demand, we could experience shipment delays or interruptions and increased
manufacturing costs, which could also have a material adverse effect on our revenues and profitability.

If there are unexpected increases in demand for our products, we may be required to obtain additional raw materials in order to manufacture products to
meet the increase in demand. However, some raw materials require significant ordering lead time and some are currently obtained from a sole supplier or a
limited group of suppliers. It is also possible that one or more of our suppliers may become unwilling or unable to deliver materials to us. Any shortfall in
our supply of raw materials and components, or our inability to quickly and cost‑effectively obtain alternative sources for this supply, could have a material
adverse effect on our ability to meet increased demand for our products. This could negatively affect our total revenues or cost of sales and related profits.

29

If we are unable to meet customer demand for our products, it could also harm our relationships with our customers and impair our reputation within the
industry. This, in turn, could have a material adverse effect on our business.

Risks Related to Our Products

Industry adoption of alternative technology to our COVID-19 Diagnostic Test Systems could negatively impact our ability to compete successfully.

Of the 263 manufacturers and commercial laboratories to receive an EUA for COVID-19 diagnostics as of December 31, 2021, 66 were for serology tests,
200 were for molecular tests, and 14 were for antigen tests. Customers or the industry as a whole could adopt alternative technologies for testing, including
molecular point of care testing, which could result in lower demand for our antigen test. Various advances in the treatment and monitoring of patients could
cause  lower  demand  for  the  COVID-19  Diagnostic  Test  Systems,  including  our  revised  DPP  SARS  CoV  2  Antigen  System  or  for  antigen  testing  for
COVID-19 as a whole.

COVID-19 is prone to genetic mutations that may impact the ability of the COVID-19 Diagnostic Test Systems to adequately detect COVID-19, SARS-
CoV-2 antigens and antibodies, and could adversely affect demand for the COVID-19 Diagnostic Test Systems and harm our competitive position.

False test results are a risk with all laboratory tests, including COVID-19 diagnostic tests. False results can occur in the presence or absence of a mutation
in the COVID-19 virus. Multiple variations of the virus that causes COVID-19 are circulating globally and within the United States, including variants of
concern initially identified in California, Brazil, South Africa and the United Kingdom. In the presence of a mutation in the virus, false results can occur if
a mutation occurs in the region of the virus that the test is designed to assess. False results may occur with the COVID-19 Diagnostic Test Systems in the
presence  or  absence  of  one  or  more  COVID-19  mutations.  If  false  negatives  occur  with  the  COVID-19  Diagnostic  Test  Systems,  it  will  may  reduce
customer confidence in the accuracy of the COVID-19 Diagnostic Test Systems and harm our competitive position.

For our business to succeed in the future, our current and future products must receive market acceptance.

Market  acceptance  and  the  timing  of  such  acceptance,  of  our  new  products  or  technologies  is  necessary  for  our  future  success.  To  achieve  market
acceptance, we and our distributors will likely be required to undertake substantial efforts and spend significant funds to inform every one of the existence
and perceived benefits of our products. We also may require government funding for the purchase of our products to help create market acceptance and
expand the use of our products.

It may be difficult evaluate the market reaction to our products and our marketing efforts for new products may not be successful. The government funding
we receive may be limited for new products. As such, there can be no assurance that any products will obtain significant market acceptance and fill the
market need that is perceived to exist on a timely basis, or at all.

We may not have sufficient resources to effectively introduce and market our products, which could materially harm our operating results.

Introducing  and  achieving  market  acceptance  for  our  new  products  will  require  substantial  marketing  efforts  and  will  require  us  and/or  our  contract
partners, sales agents, and/or distributors to make significant expenditures of time and money. In some instances we will be significantly or totally reliant
on the marketing efforts and expenditures of our contract partners, sales agents, and distributors. If they do not have or commit the expertise and resources
to effectively market the products that we manufacture, our operating results will be materially harmed.

New developments in health treatments and non‑diagnostic products may reduce or eliminate the demand for our products.

The  development  and  commercialization  of  products  outside  of  the  diagnostics  industry  could  adversely  affect  sales  of  our  products.  For  example,  the
development of a safe and effective vaccine to COVID-19 or HIV or treatments for other diseases or conditions that our products are designed to detect,
could reduce or eventually eliminate the demand for our HIV or other diagnostic products and result in a loss of revenues.

Our future success will depend on our ability to cost-effectively increase manufacturing production capacity through the implementation of additional
customized manufacturing automation equipment.

If  we  successfully  commercialize  the  COVID-19  Diagnostic  Test  Systems  or  other  new  products,  one  of  our  key  challenges  will  be  to  increase  our
production  capacity  to  meet  sales  demand  while  maintaining  product  quality  and  reducing  production  costs.  Our  primary  strategy  to  cost-effectively
increase product capacity has been to implement customized automation equipment, and we have entered into agreements to acquire additional customized
automation equipment. The equipment we order may not be delivered in a timely manner, and, once delivered, the equipment may require significant time
and effort in order to operate in the manner required to produce high quality products. We experienced significant unexpected delays before our current
automation equipment operated in the manner for which it was designed. The investments we make in this equipment may not yield the anticipated labor
and  material  efficiencies.  If  we  are  not  successful  in  introducing  COVID-19  Diagnostic  Test  Systems  or  other  new  products  in  accordance  with  our
operating plans, we do not have the right to terminate the existing purchase orders for additional automation equipment and we may have excess capacity
for a period of time. Our business, financial condition and results of operations could be harmed if we are unable to timely obtain automation equipment
that meets our requirements or if there are significant increases in the costs of equipment.

Customer concentration creates risks for our business.

A significant portion of our revenues each year comes from a few large customers. Bio-Manguinhos constituted 51% of our total revenues in 2021 and 25%
of our total revenues in 2020. We had another customer that accounted for 10% of our total revenues in 2021, and a third customer that accounted for 12%
of  our  revenue  in  2020.  To  the  extent  that  Bio-Manguinhos  or  any  other  large  customer  fails  to  meet  its  purchase  commitments,  changes  its  ordering
patterns or business strategy, or otherwise reduces its purchases or stops purchasing our products, or if we experience difficulty in meeting the demand by
these customers for our products, our revenues and results of operations could be adversely affected.

Sales cycles for our products can be lengthy, which can cause variability and unpredictability in our business.

Some of our products may require lengthy and unpredictable sales cycles, which makes it more difficult to accurately forecast revenues in a given period
and may cause revenues and operating results to vary from period to period. Our products may involve sales to large public and private institutions which
may require many levels of approval and may be dependent on economic or political conditions and the availability of grant awards or other funding from
government or public health agencies which can vary from period to period. There can be no assurance that purchases or funding from these agencies will
occur  or  continue,  especially  if  current  negative  economic  conditions  continue  or  intensify.  As  a  result,  we  may  expend  considerable  resources  on
unsuccessful sales efforts or we may not be able to complete transactions at all or on a schedule and in an amount consistent with our objectives.

We may face product liability claims for injuries.

The testing, manufacturing and marketing of medical diagnostic products involves an inherent risk of product liability claims. If we cannot successfully
defend ourselves against product liability claims, we may incur substantial liabilities or be required to limit or cease sales of our products. We cannot be
sure that we will not incur liabilities in excess of the policy limits of our existing product liability insurance coverage or that we will be able to continue to
obtain adequate product liability insurance coverage in the future at an acceptable cost, or at all. In addition, a defect in the design or manufacture of our
products could have a material adverse effect on our reputation in the industry and subject us to claims of liability for injury and otherwise. Any substantial
underinsured loss resulting from such a claim could have a material adverse effect on our profitability, and the damage to our reputation in the industry
could have a material adverse effect on our business.

31

Table of Contents

Our customers may not adopt rapid point‑of‑care diagnostic testing.

Rapid point‑of‑care tests are beneficial because, among other things, they can be administered by healthcare providers in their own facilities or used by
consumers at home without sending samples to central laboratories. But currently the majority of diagnostic tests used by physicians and other healthcare
providers  in  the  U.S.  are  provided  by  clinical  reference  laboratories  and  hospital‑based  laboratories.  In  some  international  markets,  such  as  Europe,
diagnostic testing is performed  primarily  by  centralized  laboratories.  Future  sales  of  our  products  will  depend,  in  part,  on  our  ability  to  expand  market
acceptance  of  rapid  point‑of‑care  testing  and  successfully  compete  against  laboratory  testing  methods  and  products.  However,  we  expect  that  clinical
reference and other hospital‑based laboratories will continue to compete vigorously against our rapid point‑of‑care products. Even if we can demonstrate
that our products are more cost effective, save time, or have better performance or other benefits, physicians, other healthcare providers and consumers may
resist changing to rapid point‑of‑care tests and instead may choose to obtain diagnostic results through laboratory tests. If we fail to achieve and expand
market acceptance of our rapid point‑of‑care diagnostic tests with customers, it would have a negative effect on our future sales growth.

If our products do not perform properly, it may affect our revenues, stock price and reputation.

Our products may not perform as expected. For example, a defect in one of our diagnostic products or a failure by a customer to follow proper testing
procedures may cause the product to report inaccurate information. Identifying the root cause of a product performance or quality issue can be difficult and
time consuming.

If  our  products  do  not  to  perform  in  accordance  with  the  applicable  label  claims  or  otherwise  in  accordance  with  the  expectations  or  needs  of  our
customers,  customers  may  switch  to  a  competing  product  or  otherwise  stop  using  our  products,  and  our  revenues  could  be  negatively  affected.  If  this
occurs, we may be required to implement holds or product recalls and incur warranty obligations. Furthermore, the poor performance by one or more of our
products could have an adverse effect on our reputation, our continuing ability to sell products and the price of our common stock.

Financial, Economic and Financing Risks

Because  of  our  liquidity  limitations,  we  have  concluded  there  is  a  substantial  doubt  about  our  ability  to  continue  as  a  going  concern  and  we  may
require additional capital to fund our operations, which capital may not be available to us on acceptable terms or at all.

As described under “Part I, Item 1. Business─Overview”, “Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of
Operations-Substantial Doubt as to Going Concern Status” and “─Liquidity and Capital Resources”, management has determined we could not be certain
that our plans and initiatives to increase our total revenues and improve our liquidity position would be effectively implemented within one year after the
filing  date  of  this  report,  when  the  consolidated  financial  statements  accompanying  this  report,  or  the  Accompanying  Financial  Statements,  are  being
issued.  Without  giving  effect  to  the  prospect  of  raising  additional  capital  pursuant  to  our  at-the-market  offerings  under  the  ATM  Agreement,  increasing
product revenue in the near future or executing other mitigating plans, many of which are beyond our control, it is unlikely that we will be able to generate
sufficient cash flows to meet our required financial obligations, including our debt service and other obligations due to third parties. The existence of these
conditions raises substantial doubt about our ability to continue as a going concern for the twelve-month period following the filing date of this report,
when the Accompanying Financial Statements are being issued.

Our diagnostic test products require ongoing funding to continue our current development and operational plans, and we have a history of net losses. We
intend  to  continue  to  expend  substantial  resources  in  the  short  term  in  connection  with  the  July  Purchase  Orders  (see  “Part  II,  Item  7.  Management’s
Discussion and Analysis of Financial Condition”), but we may encounter challenges in fulfilling our obligations, and therefore receiving revenue, under
those purchase orders. See “─Because of our liquidity and operational limitations, including the availability of staffing and supply chain resources that are
necessary but outside of our control, we will not be able to timely fulfill all of the requirements of the July Purchase Order from Bio‑Manguinhos and it is
difficult to reliably estimate the extent to which we will be able to timely meet those requirements” below. We will also incur costs associated with research
and development activity, corporate administration, business development, debt service, marketing and selling of our products, and litigation. In addition,
other unanticipated costs may arise.

As of December 31, 2021, we had outstanding indebtedness of $20.0 million under the Credit Agreement. We may face further liquidity challenges if we
are unable to meet obligations set forth in the Credit Agreement, including a financial covenant requiring that we achieve specified minimum total revenue
amounts measured as of the end of each quarter. A breach of the minimum total revenue covenant or any other covenant in the Credit Agreement would
result in a default under the Credit Agreement, which could enable the Lender to declare all amounts outstanding thereunder, together with accrued interest,
to be immediately due and payable. We cannot assure you that, in such an event, we would have sufficient assets to pay  amounts  due  under  the  Credit
Agreement. See “─The failure to comply with the terms of the Credit Agreement could result in a default under its terms and, if uncured, could result in
action against our pledged assets and dilution of our stockholders” below.

32

 
Table of Contents

As  a  result,  we  may  need  to  raise  capital  in  one  or  more  debt  or  equity  offerings  to  fund  our  operations  and  obligations.  There  can  be  no  assurance,
however, that we will be successful in raising the necessary capital or that any such offering will be available to us on terms acceptable to us, or at all. If we
are unable to raise additional capital that may be needed on terms in sufficient amounts or on terms acceptable to us, it could have a material adverse effect
on our company. If we are unable to raise additional capital in sufficient amounts or on terms acceptable to us, we may have to significantly delay, scale
back or discontinue our deliveries under our outstanding customer purchase orders or the development or commercialization of one or more of our products
or  one  or  more  of  our  other  research  and  development  initiatives.  The  outbreak  of  the  COVID-19  pandemic  has  significantly  disrupted  world  financial
markets, negatively impacted U.S. market conditions and may reduce opportunities for us to seek out additional funding. A decline in the market price of
our common stock, whether or not coupled with the suspension of trading of our common stock on the Nasdaq Capital Market, could make it more difficult
for us to sell equity or equity-related securities in the future at a time and price that we deem appropriate, or at all.

Continuing doubt about our ability to continue as a going concern may materially and adversely affect the price of our common stock, and it may be more
difficult for us to obtain financing. Any uncertainty about our ability to continue as a going concern may also adversely affect our relationships with current
and future employees, suppliers, vendors, customers, grantors, creditors, regulators and investors, who may become concerned about our ability to meet our
ongoing financial obligations. There is risk that, among other things:

•

•
•
•

•

third parties lose confidence in our ability to continue to operate in the ordinary course, which could impact our ability to execute on our business
strategy;
it may become more difficult for us to attract, retain or replace employees;
employees could be distracted from performance of their duties;
we could lose some or a significant portion of our liquidity, either due to stricter credit terms from vendors, or, in the event we undertake a Chapter 11
proceeding and conclude that we need to procure debtor-in-possession financing, an inability to obtain any needed debtor-in-possession financing or to
provide adequate protection to certain secured lenders to permit us to access some or all of our cash; and
our vendors and service providers could seek to renegotiate the terms of our arrangements, terminate their relationships with us or require financial
assurances from us.

The Accompanying Financial Statements have been prepared assuming we will continue as a going concern, which contemplates continuity of operations,
realization of assets and the satisfaction of liabilities in the normal course of business for the twelve-month period following the date of this report. As
such, the Accompanying Financial Statements do not include any adjustments relating to the recoverability and classification of assets and their carrying
amounts, or the amount and classification of liabilities that may result should we be unable to continue as a going concern.

Because of our liquidity and operational limitations, including the availability of staffing and supply chain resources that are necessary but outside of
our control, we may not be able to timely fulfill all of the requirements of the July Purchase Order from Bio-Manguinhos and it is difficult to reliably
estimate the extent to which we will be able to timely meet those requirements.

In  July  2021  we  received  the  July  Purchase  Orders,  which  we  had  been  pursuing  for  an  extended  period  of  time.  See  “Part  II,  Item  7.  Management’s
Discussion  and  Analysis  of  Financial  Condition  below.  Our  delivery  of  the  full  number  of  tests  covered  by  each  of  the  July  Purchase  Orders  may  be
affected by limitations of our supply chain, staffing and liquidity, including matters that are outside our control. We have established internal plans designed
to maximize the number of tests we can deliver timely, or at all, pursuant to the July Purchase Orders, and we expect to continue to revise those plans as we
obtain  new  information.  The  number  of  uncertainties  related  to  third  parties  -  including  the  availability  of  required  personnel,  raw  materials  and  other
resources - currently preclude us, however, from reliably estimating the extent to which we will be able to fulfill the July Purchase Orders on time and at an
acceptable cost, or at all. Our ability to generate revenue from the July Purchase Orders, and the margins we can realize from that revenue, will depend on
the availability and cost of human, material and other resources required to build and deliver tests in accordance with the July Purchase Orders.

33

 
Table of Contents

In anticipation of receipt of significant purchase orders in 2021, during the first half of 2021 we continued to invest in automating our test manufacturing
processes,  all  of  which  are  now  based  in  the  United  States,  by,  among  other  actions,  validating  and  implementing  automated  lines  to  expand  our
manufacturing  capabilities.  We  did  not  know,  however,  the  number  or  mix  of  tests  for  which  purchase  orders  might  be  received,  and  we  now  need  to
configure  our  automated  manufacturing  lines  for  the  most  efficient  use  feasible,  subject  to  numerous  staffing  and  other  constraints,  in  producing  DPP
SARS-CoV-2 Antigen tests and HIV 1/2 STAT-PAK Assays contemplated by the July Purchase Orders. The number of tests to be delivered pursuant to the
July Purchase Orders significantly exceeds the capacity of our automated manufacturing lines. We have neither the time nor the resources to increase our
automated manufacturing capacity meaningfully during the delivery periods contemplated by the July Purchase Orders.

We therefore are relying upon manual assembly processes to produce a significant portion of the tests deliverable under the July Purchase Orders and other
customer orders, which require that we successfully recruit, hire and train a significant number of personnel for employment at our Long Island, New York
facilities.  Identifying,  hiring  and  retaining  assembly  line,  formulations,  production,  warehouse,  quality  control  and  other  personnel  for  our  Long  Island
facilities at acceptable compensation levels has been challenging in the past, and those circumstances have been exacerbated by the continuing effects of
the COVID-19 pandemic, which may discourage potential employees from returning to a physical worksite at compensation levels that are acceptable to
us, or at all. Upon receiving the July Purchase Orders, we launched a broad campaign to recruit and retain manufacturing and other personnel and, more
recently, we temporarily increased pay for manufacturing personnel. Our recruiting efforts have not, however, proven sufficient to overcome the tight labor
market that has been impacting many U.S. companies, including employers on Long Island, and we have not been able to hire the number of manufacturing
personnel required to meet our internal plans for delivery of all of the tests contemplated by the July Purchase Orders. Our continued inability to identify
and  hire  sufficient  numbers  of  manufacturing  personnel,  and  to  manage  turnover  of  currently  existing  and  newly  hired  personnel,  would  continue  to
materially limit our ability to deliver tests under the July Purchase Orders.

Our delivery of tests covered by the July Purchase Orders has also been negatively affected by limitations on raw materials, components and other supplies.
We must obtain additional supplies in order to manufacture tests to meet the requirements of the July Purchase Orders. Some supplies require significant
ordering lead time, and some are currently obtained from a sole supplier or a limited group of suppliers. With some of these suppliers, we do not have long
term agreements and instead purchase materials, components and other supplies through a purchase order process. The COVID-19 pandemic has disrupted
nearly every aspect of the global supply chain, including the manufacturing or delivery of some of the key supplies used in our tests. Many suppliers are
experiencing shortages of required personnel as the result of the tight labor market and underlying raw material commodities. Some suppliers have been
unable to deliver supplies in the quantity we need or at all. As a result, these suppliers may stop supplying us components and materials, limit the allocation
of supply and equipment to us due to increased industry demand, or significantly increase their prices at any time with little or no advance notice. Because
of  the  foregoing  limitations,  as  exacerbated  by  the  quantities  and  timing  of  supplies  required  to  timely  fulfill  the  July  Purchase  Orders,  we  have  been
required to seek to identify new sources of supplies to replace or augment our past sources, which has proven difficult to do in a reasonable time period and
on commercially reasonable terms, if at all. Moreover, scarcity has caused increases in the cost of some supplies. Our inability to timely obtain required
supplies has had an adverse effect on our ability to timely fulfill the July Purchase Orders as well as on our total revenues, cost of sales, related margin and
cash flow.

We have incurred losses in recent years and we are uncertain about our future profitability and cash flow.

We incurred an operating loss every year from 2014 through 2021. Under our operating plans, we have made, and plan to continue to make, significant
investments  in  our  production  capacity,  including  in  expanding  facilities  and  automating  manufacturing,  and  in  our  sales  and  marketing,  regulatory
approval, and research and development activities. Our ability to achieve profitability and generate cash flow in the future will depend on our ability to
increase sales of our existing products and to successfully introduce new and enhanced products into the marketplace, all while controlling and managing
our expenses consistent with our operating plan.

Because we do not currently have an EUA from the FDA for any of the COVID-19 Diagnostic Test Systems, we have been unable to increase our revenues
in accordance with our operating plan. As a result, our operating results have not met our expectations. If we experience a continuing delay in obtaining, or
are unable to obtain, an EUA for one or more of our COVID-19 Diagnostic Test Systems, our operating results will be further harmed and we may not be
able  to  generate  the  cash  flow  needed  to  fund  the  investments  in  our  production  capacity  and  other  activities.  In  such  an  event,  we  will  be  required  to
implement one or both of the following:

• We  could  reduce  the  level,  or  otherwise  delay  the  timing,  of  the  anticipated  investments  in  our  production  capacity  and  other  activities,  which
would  likely  curtail  or  delay  the  growth  in  our  business  contemplated  by  our  operating  plan  and  could  impair  or  defer  our  ability  to  achieve
profitability and generate cash flow. Moreover, if we were to further reduce the number of our personnel, there can be no assurance that we would
be able, when desirable, to successfully rehire or rebuild our workforce.

• We could raise additional funds through public or private financings, strategic relationships, or other arrangements, to the extent funding would be
available to us on acceptable terms or at all. If we succeed in raising additional funds through the issuance of equity or convertible securities, then
the issuance could result in substantial dilution to existing stockholders. Furthermore, the holders of these new securities or debt may have rights,
preferences and privileges senior to those of the holders of our common stock.

In such circumstances, we also would need to forego acquisition opportunities, which could impede our ability to grow our business.

Our financial results may fluctuate.

From quarter to quarter and year to year, our operating results can fluctuate, which could cause our growth or financial performance to fail to meet the
expectations of investors and securities analysts. Sales to our distributors and other customers may not meet expectations because of lower than expected
customer  demand  or  other  factors,  including  continued  economic  volatility  and  disruption,  reduced  governmental  funding,  and  other  circumstances
described  elsewhere  in  this  report.  A  variety  of  factors  could  also  contribute  to  the  variability  of  our  financial  results,  including  infrequent,  unusual  or
unexpected changes in revenues or costs.

Different products provide dissimilar contributions to our gross product margin. Accordingly, our operating results could also fluctuate and be negatively
affected by the mix of products sold and the relative prices and gross product margin contribution of those products. Failure to achieve operating results
consistent with the expectations of investors and securities analysts could adversely affect our reputation and the price of our common stock.

The failure to comply with the terms of the Credit Agreement could result in a default under its terms and, if uncured, could result in action against our
pledged assets and dilution of our stockholders.

On September 3, 2019, we and certain of our subsidiaries, as guarantors, entered into the Credit Agreement, under which we received a $20,000,000 senior
secured  term  loan  credit  facility  that  was  drawn  in  full  on  September  4,  2019.  The  Credit  Agreement  is  secured  by  a  first  priority,  perfected  lien  on
substantially all of our property and assets, including our equity interests in our subsidiaries. See “Part II, Item 7. Management’s Discussion and Analysis
of Financial Condition and Results of Operations─Liquidity and Capital Resources─Sources of Funds─Credit Agreement.”

The Credit Agreement also contains financial covenants requiring that we (a) maintain aggregate unrestricted cash of not less than $3,000,000 at all times,
which  must  be  held  in  one  or  more  accounts  subject  to  the  first  priority  perfected  security  interests  of  the  Lender  under  the  Credit  Agreement,  and  (b)
achieve specified minimum total revenue requirements for the twelve months preceding each quarter end. The minimum total revenue amounts over the
next year increase from $42.0 million for the twelve months ending March 31, 2022 to $47.4 million for the twelve months ending December 31, 2022 (see
note 13 to the Accompanying Financial Statements). These minimum revenue requirements were developed for purposes of the Credit Agreement and do
not reflect the internal estimates and plans used by our management and board of directors to establish operational goals for managing our business. The
minimum revenue requirements for the twelve months ending December 31, 2022 do not, for example, take into account the challenges we are facing in
ramping up production, including hiring personnel and obtaining commitments from our supply chain as described above in “─Because of our liquidity and
operational limitations, including the availability of staffing and supply chain resources that are necessary but outside of our control, we will not be able to
timely fulfill all of the requirements of the July Purchase Orders and it is difficult to reliably estimate the extent to which we will be able to timely meet
those requirements.”

35

 
 
 
 
Table of Contents

In addition, the Credit Agreement contains covenants that restrict our ability to finance future operations or capital needs or to engage in other business
activities. The Credit Agreement restricts the ability of our company and the restricted subsidiaries to:

incur, assume or guarantee additional Indebtedness (as defined in the Credit Agreement);
repurchase capital stock;

•
•
• make other restricted payments, including paying dividends and making investments;
•
•
•
•
•

create liens;
sell or otherwise dispose of assets, including capital stock of subsidiaries;
enter into agreements that restrict dividends from subsidiaries;
enter into mergers or consolidations; and
enter into transactions with affiliates.

A breach of the minimum total revenue covenant or any other covenant in the Credit Agreement would result in a default under the Credit Agreement.
Upon an event of default under the Credit Agreement, the Lender could elect to declare all amounts outstanding thereunder, together with accrued interest,
to be immediately due and payable. In such an event, there can be no assurance that we would have sufficient liquidity to fund payment of the amounts that
would be due under the Credit Agreement or that, if such liquidity were not available, we would be successful in raising additional capital on acceptable
terms, or at all, or in completing any other endeavor to continue to be financially viable and continue as a going concern. Our inability to raise additional
capital  on  acceptable  terms  in  the  near  future,  whether  for  purposes  of  funding  payments  required  under  the  Credit  Agreement  or  providing  additional
liquidity needed for our operations, could have a material adverse effect on our business, prospects, results of operations, liquidity and financial condition.

Servicing our debt will require a significant amount of cash. Our ability to generate sufficient cash to service our debt depends on many factors beyond
our control.

Our ability to make payments on and to refinance our debt, to fund planned capital expenditures, and to maintain sufficient working capital depends on our
ability to generate cash in the future. This, to a certain extent, is subject to general economic, financial, competitive, legislative, regulatory and other factors
that are beyond our control. We cannot assure you that our business will generate sufficient cash flow from operations or from other sources in an amount
sufficient to enable us to service our debt or to fund our other liquidity needs. Our operations used $30.9 million in cash in 2021 and $18.9 million in 2020.
If  our  cash  flow  and  capital  resources  are  insufficient  to  allow  us  to  make  scheduled  payments  on  our  debt,  we  may  need  to  seek  additional  capital  or
restructure or refinance all or a portion of our debt on or before the maturity thereof, any of which could have a material adverse effect on our business,
financial  condition  or  results  of  operations.  We  cannot  assure  you  that,  if  needed,  we  would  be  able  to  refinance  any  of  our  debt  on  commercially
reasonable terms or at all, or that the terms of that debt will allow any of the above alternative measures or that these measures would satisfy our scheduled
debt service obligations. If we are unable to generate sufficient cash flow to repay or refinance our debt on favorable terms, it could significantly adversely
affect  our  financial  condition.  Our  ability  to  restructure  or  refinance  our  debt  will  depend  on  the  condition  of  the  capital  markets  and  our  financial
condition. Any refinancing of our debt could be at higher interest rates and may require us to comply with more onerous covenants, which could further
restrict our business operations. There can be no assurance that we will be able to obtain any financing when needed.

Our ability to utilize our net operating loss carryforwards and certain other tax attributes may be limited.

Our ability to utilize our federal net operating loss and tax credit carryforwards may be limited under Sections 382 and 383 of the U.S. Internal Revenue
Code of 1986, or the Code. The limitations apply if we experience an “ownership change” (generally defined as a greater than 50 percentage point change
(by value) in the ownership of our equity by certain stockholders over a rolling three-year period). Similar provisions of state tax law may also apply to
limit the use of our state net operating loss carryforwards.

We experienced an ownership change in 2004 and 2006, and we estimate a portion of our existing federal net operating loss carryforwards are subject to an
annual  limitation  under  Section  382  of  the  Code.  Since  our  ownership  change  in  2006,  we  have  not  assessed  whether  an  ownership  change  has
subsequently  occurred.  If  we  have  experienced  an  ownership  change  at  any  time  since  our  ownership  change  in  2006,  we  may  already  be  subject  to
limitations on our ability to utilize our net operating losses and other tax attributes generated before such additional ownership change to offset post-change
taxable  income.  In  addition,  future  changes  in  our  stock  ownership,  which  may  be  outside  of  our  control,  may  trigger  an  ownership  change  and,
consequently, the limitations under Sections 382 and 383 of the Code. As a result, if or when we earn net taxable income, our ability to use our pre-change
net operating loss carryforwards and other tax attributes to offset such taxable income may be subject to limitations, which could adversely affect our future
cash flows.

The LIBOR calculation method may change, and LIBOR is expected to be phased out after 2021, which may adversely affect our interest expenses
under the Credit Agreement.

Loans under the Credit Agreement bear interest at a rate per annum equal to the sum of (a) the greater of the one‑month London Interbank Offered Rate, or
LIBOR, and 2.5% plus (b) 8.75%. At any time at which an event of default has occurred and is continuing, the interest rate will increase by 4.0%. Accrued
interest is payable on a monthly basis. On July 27, 2017, the U.K. Financial Conduct Authority announced that it will no longer require banks to submit
rates for the calculation  of  LIBOR  after  2021.  On  November  30,  2020,  ICE  Benchmark  Administration,  or  IBA,  the  administrator  of  LIBOR,  with  the
support of the United States Federal Reserve and the United Kingdom’s Financial Conduct Authority, announced plans to consult on ceasing publication of
USD LIBOR on December 31, 2021 for only the one week and two month USD LIBOR tenors, and on June 30, 2023 for all other USD LIBOR tenors.
While this announcement extended the transition period to June 2023, the United States Federal Reserve concurrently issued a statement advising banks to
stop new USD LIBOR issuances by the end of 2021. In light of these recent announcements, the future of LIBOR at this time is uncertain and any changes
in the methods by which LIBOR is determined or regulatory activity related to LIBOR’s phaseout could cause LIBOR to perform differently than in the
past or cease to exist.

In response to concerns regarding the future of LIBOR, the Board of Governors of the Federal Reserve System and the Federal Reserve Bank of New York
convened the Alternative Reference Rates Committee, or ARRC, to identify alternatives to LIBOR. The ARRC has recommended benchmark replacement
procedures  to  assist  issuers  in  continued  capital  market  entry  while  safeguarding  against  LIBOR’s  discontinuation.  The  initial  steps  in  the  ARRC’s
recommended provision reference variations of the Secured Overnight Financing Rate, or SOFR. It is not possible to predict the effect of these changes,
other reforms or the establishment of alternative reference rates in the United States or elsewhere.

Pursuant to the Credit Agreement, if LIBOR becomes unavailable in the future an alternative benchmark rate will apply. To the extent our interest rates
increase as a result, our interest expense will increase, in which event we may have difficulties making interest payments and funding our other fixed costs,
and our available cash flow for general corporate requirements may be adversely affected.

Our operating results may be negatively affected by changes in foreign currency exchange rates.

In the past our exposure to foreign currency exchange rate risk has not been material. Nevertheless, sales of our products are subject to currency risks, since
changes in the values of foreign currencies relative to the value of the U.S. dollar can render our products comparatively more expensive. The fluctuations
in the exchange rate could negatively impact international sales of our products, as could changes in the general economic conditions.

37

Table of Contents

The  revenues  and  expenses  of  our  Malaysian,  German  and  Brazilian  subsidiaries  are  recorded  in  Malaysian  Ringgit,  in  Euros  and  Brazilian  Real,
respectively. Revenues and expenses denominated in foreign currencies are translated into U.S. dollars for purposes of reporting our consolidated financial
results, and, consequently, our operating results reflect exposure to foreign currency exchange rates, which could increase in the future.

Our foreign subsidiaries’ revenues and expenses and the translation of their financial results into U.S. dollars may be negatively affected by fluctuations in
the exchange rate. Favorable movement in exchange rates have benefited us in prior periods. However, where there are unfavorable currency exchange rate
fluctuations,  our  consolidated  financial  statements  could  be  negatively  affected.  Furthermore,  fluctuations  in  exchange  rates  could  affect  year‑to‑year
comparability of operating results. In the past, we have not generally entered into hedging instruments to manage our currency exchange rate risk, but we
may need to do so in the future. However, our attempts to hedge against these risks may not be successful. If we are unable to successfully hedge against
unfavorable foreign currency exchange rate movements, our consolidated financial results may be adversely impacted.

We operate in countries where there is or may be widespread corruption.

We have a policy in place prohibiting our employees, distributors and agents from engaging in corrupt business practices, including activities prohibited by
the U.S. Foreign Corrupt Practices Act. Nevertheless, because we work through independent sales agents and distributors outside the United States, we do
not have control over the day to day activities of such independent agents and distributors. In addition, in the donor funded markets in Africa where we sell
our  products,  there  is  significant  oversight  from  PEPFAR,  the  Global  Fund,  and  advisory  committees  comprised  of  technical  experts  concerning  the
development  and  establishment  of  national  testing  protocols.  This  is  a  process  that  includes  an  overall  assessment  of  a  product  that  includes  extensive
evaluations  of  product  performance,  as  well  as  price  and  delivery.  In  Brazil,  where  we  have  had  numerous  product  collaborations  with  FIOCRUZ,  the
programs  through  which  our  products  may  be  deployed  are  all  funded  by  the  Brazilian  Ministry  of  Health.  Although  FIOCRUZ  is  affiliated  with  the
Brazilian Ministry of Health, which is FIOCRUZ’s sole customer, FIOCRUZ is not the exclusive supplier for the Ministry of Health. However, because
each of our previous collaborations with FIOCRUZ incorporates a technology transfer aspect, we believe we have a competitive advantage versus other
suppliers to the Brazilian Ministry of Health, assuming other aspects of our product offering through FIOCRUZ are otherwise competitive in comparison.
We have no knowledge or reason to know of any activities by our employees, distributors or sales agents of any actions which could be in violation of the
FCPA, although there can be no assurance of this. In addition, corruption is a problematic factor in doing business in Brazil, and, to the extent bribery and
similar practices continue to exist in Brazil, we may be at a competitive disadvantage in gaining business in Brazil, particularly when competing with non
U.S. companies.

Our subsidiary Chembio Diagnostics Malaysia Sdn. Bhd. is located in Malaysia. There have been numerous high‑profile corruption cases, and corruption is
one  of  the  most  problematic  factors  for  doing  business  in  Malaysia.  While  the  Malaysian  government  has  acknowledged  the  problem,  it  appears  that
endemic corruption is continuing and that market‑based principles are not applied in cases involving individuals with high‑level political access. To the
extent bribery and similar practices continue to exist in Malaysia, U.S. companies such as ours, which are subject to U.S. laws making it illegal to pay
bribes to foreign officials, may make us less competitive in winning business in Malaysia when competing with non‑U.S. companies.

We base our estimates or judgments relating to critical accounting policies on assumptions that can change or prove to be incorrect.

Our  financial  statements  have  been  prepared  in  accordance  with  accounting  principles  generally  accepted  in  the  United  States  and  our  discussion  and
analysis of financial condition and results of operations is based on such statements. The preparation of financial statements requires management to make
estimates  and  assumptions  that  affect  the  amounts  reported  in  the  financial  statements  and  accompanying  notes.  We  continuously  evaluate  significant
estimates  used  in  preparing  our  financial  statements,  including  those  related:  to  (1)  revenue  recognition,  including  uncertainties  related  to  variable
consideration, milestones and bill and hold arrangements; (2) stock based compensation; (3) allowance for uncollectible accounts receivable; (4) inventory
reserves  and  obsolescence;  (5)  customer  sales  returns  and  allowances;  (6)  contingencies;  (7)  income  taxes;  (8)  goodwill  and  intangibles;  (8)  business
acquisition; and (10) research and development costs.

38

 
Table of Contents

Our estimates are based on historical experience and various other assumptions that we believe to be reasonable, as set forth in our discussion and analysis
of financial condition and results of operations, the results of which form the basis for making judgments about the carrying values of assets and liabilities
that  are  not  readily  apparent  from  other  sources.  Actual  results  may  differ  from  these  and  other  estimates  if  our  assumptions  change  or  if  actual
circumstances differ from those in our assumptions. If our operating results fall below the expectations of securities analysts and investors, the price of our
common Stock may decline.

Risks Related to Intellectual Property

Our success depends on our ability to protect our proprietary technology. We rely on trade secret laws and agreements with our key employees and
other third parties to protect our proprietary rights, and we cannot be sure that these laws or agreements will adequately protect our rights.

Our industry places considerable importance on obtaining patent, trademark and trade secret protection, as well as other intellectual property rights, for new
technologies, products and processes. Our success depends, in part, on our ability to develop and maintain a strong intellectual property portfolio or obtain
licenses  to  patents  and  technologies,  both  in  the  United  States  and  in  other  countries.  If  we  cannot  continue  to  develop,  obtain  and  protect  intellectual
property rights, our revenues and gross profits could be adversely affected. Moreover, our current and future licenses or other rights to patents and other
technologies may not be adequate for the operation of our business.

As appropriate, we intend to file patent applications and obtain patent protection for our proprietary technology. These patent applications and patents will
cover, as applicable, compositions of matter for our products, methods of making those products, methods of using those products and apparatuses relating
to the use or manufacture of those products. However, there have been changes to the patent laws and proposed changes to the rules of the U.S. Patent and
Trademark  Office,  which  may  impact  our  ability  to  protect  our  technology  and  enforce  our  intellectual  property  rights.  For  example,  in  2011,  the  U.S.
enacted sweeping changes to the U.S. patent system under the Leahy‑Smith America Invents Act, including changes that would transition the U.S. from a
“first‑to‑invent” system to a “first‑to‑file” system and alter the processes for challenging issued patents. These changes could increase the uncertainties and
costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents.

We believe that factors such as the technological and creative skills of our personnel, strategic relationships, new product developments, frequent product
enhancements  and  name  recognition  are  essential  to  our  success.  All  our  management  personnel  are  bound  by  non‑disclosure  agreements.  If  personnel
leave our employment, in some cases we would be required to protect our intellectual property rights pursuant to common law theories which may be less
protective than provisions of employment, non‑competition or non‑disclosure agreements.

We  seek  to  protect  our  proprietary  products  under  trade  secret  and  copyright  laws,  enter  into  license  agreements  for  various  materials  and  methods
employed  in  our  products,  and  enter  into  strategic  relationships  for  distribution  of  the  products.  These  strategies  afford  only  limited  protection.  We
currently have some foreign patents issued, and we are seeking additional patent protection in several other foreign jurisdictions for our DPP and optical
technology. We have licenses to reagents (antigens and peptides) used in several of our products and products under development. Despite our efforts to
protect  our  proprietary  assets,  and  respect  the  intellectual  property  rights  of  others,  we  participate  in  several  markets  where  intellectual  property  rights
protections are of little or no value. This can place our products and our company at a competitive disadvantage.

Moreover, issued patents remain in effect for a fixed period and after expiration will not provide protection of the inventions they cover. Once our patents
expire,  we  may  be  faced  with  increased  competition,  which  could  reduce  our  revenues.  We  may  also  not  be  able  to  successfully  protect  our  rights  to
unpatented trade secrets and know‑how.

To facilitate development and commercialization of a proprietary technology base, we may need to obtain additional licenses to patents or other proprietary
rights from other parties. Obtaining and maintaining these licenses, which may not be available, may require the payment of up‑front fees and royalties. In
addition, if we are unable to obtain these types of licenses, our product development and commercialization efforts may be delayed or precluded.

39

Table of Contents

Any  future  intellectual  property  disputes  could  require  significant  resource  and  limit  or  eliminate  our  ability  to  sell  products  or  use  certain
technologies.

We may be required to expend substantial resources in asserting or protecting our intellectual property rights, or in defending suits related to intellectual
property rights. We may seek to enforce our patents or other intellectual property rights through litigation. Such litigation is prevalent and is expected to
continue. In our business, there are a large number of patents and patent applications similar to our products, and additional patents may be issued to third
parties relating to our product areas. We, our customers or our suppliers may be sued for infringement of patents or misappropriation of other intellectual
property rights with respect to one or more of our products. We may also have disputes with parties that license patents to us if we believe the license is no
longer needed for our products or the licensed patents are no longer valid or enforceable.

There are a large number of patents in our industry, and the claims of these patents appear to overlap in many cases. Therefore there is a significant amount
of  uncertainty  regarding  the  extent  of  patent  protection  and  infringement.  Companies  may  have  pending  patent  applications,  which  are  typically
confidential for the first eighteen months following filing that cover technologies we incorporate in our products. Accordingly, we may be subjected to
substantial damages for past infringement or be required to modify our products or stop selling them if it is ultimately determined that our products infringe
a third party’s proprietary rights. In addition, governmental agencies could commence investigations or criminal proceedings against our employees or us
relating to claims of misuse or misappropriation of another party’s proprietary rights.

If we are involved in litigation or other legal proceedings with respect to patents or other intellectual property and proprietary technology, it could adversely
affect  our  revenues,  results  of  operations,  market  share  and  business  because  (1)  it  could  consume  a  substantial  portion  of  managerial  and  financial
resources; (2) its outcome would be uncertain and a court may find that our patents are invalid or unenforceable in response to claims by another party or
that the third‑party patent claims are valid and infringed by our products; (3) the pendency of any litigation may in and of itself cause our distributors and
customers to reduce or terminate purchases of our products; (4) a court could award a preliminary and/or permanent injunction, which would prevent us
from selling our current or future products; and (5) an adverse outcome could subject us to the loss of the protection of our patents or to liability in the form
of  past  royalty  payments,  penalties,  reimbursement  of  litigation  costs  and  legal  fees,  special  and  punitive  damages,  or  future  royalty  payments,  any  of
which could significantly affect our future earnings.

Under  certain  contracts  with  third  parties,  we  may  indemnify  the  other  party  if  our  products  or  activities  have  actually  or  allegedly  infringed  upon,
misappropriated or misused another party’s proprietary rights. Furthermore, our products may contain technology provided to us by third parties, and we
may be unable to determine in advance whether such technology infringes the intellectual property rights of a third party. These other parties may also not
be required or financially able to indemnify us in the event that an infringement or misappropriation claim is asserted against us.

There  may  also  be  other  types  of  disputes  that  we  become  involved  in  regarding  intellectual  property  rights,  including  state,  federal  or  foreign  court
litigation,  and  patent  interference,  patent  reissue,  patent  reexamination,  or  trademark  opposition  proceedings  in  the  United  States  Patent  and  Trademark
Office. Opposition or revocation proceedings could be instituted in a foreign patent office as well. These proceedings permit certain persons to challenge
the validity of a patent on the grounds that it was known from the prior art. The filing of such proceedings, or the issuance of an adverse decision in such
proceedings,  could  result  in  the  loss  of  valuable  patent  rights  that  could  have  a  material  adverse  effect  on  our  business,  financial  condition,  results  of
operations and growth prospects.

Risks Related to Our Reliance on Third Parties

Our  use  of  third‑party  suppliers,  some  of  which  may  constitute  our  sole  supply  source,  for  certain  important  product  components  and  materials
presents risks that could have negative consequences for our business.

We purchase certain HIV antigens, a syphilis antigen, COVID-19 antibodies and antigens, the nitrocellulose, and certain other critical components used in
our STAT PAK, STAT VIEW, SURE CHECK and DPP product lines from a sole or limited number of sources. If for any reason these suppliers become
unwilling  or  unable  to  supply  our  antigen,  nitrocellulose,  or  other  critical  component  needs,  we  believe  that  alternative  supplies  could  be  obtained  at  a
competitive  cost.  However,  a  change  in  any  of  the  antibodies,  antigens,  nitrocellulose  or  other  critical  components  used  in  our  products  would  require
additional development work and clinical trials, as well as approval by the FDA and other regulatory agencies. In addition, it may be difficult to find such
an  alternate  supply  source  in  a  reasonable  time  period  or  on  commercially  reasonable  terms,  if  at  all.  As  a  result,  the  termination  or  limitation  of  our
relationship with one or more of these suppliers could require  significant  time  to  complete,  increase  our  costs,  and  disrupt  or  discontinue  our  ability  to
manufacture and sell the affected products. In addition, governmental purchasers or funding programs in a particular country may require that we purchase
key components from suppliers in that country, which could significantly limit our ability to obtain the components with the quality, and at the price, we
seek.

40

Table of Contents

With some of these suppliers, we do not have long‑term agreements and instead purchase components and materials through a purchase order process. As a
result,  these  suppliers  may  stop  supplying  us  components  and  materials,  limit  the  allocation  of  supply  and  equipment  to  us  due  to  increased  industry
demand, or significantly increase their prices at any time with little or no advance notice. Our reliance on a limited number of suppliers could also result in
delivery problems, reduced control over product pricing and quality, and our inability to identify and qualify another supplier in a timely manner.

Moreover, some of these suppliers may experience financial difficulties that could prevent them from supplying us with components or subassemblies used
in  the  design  and  manufacture  of  our  products.  In  addition,  these  suppliers  may  experience  manufacturing  delays  or  shut  downs  due  to  circumstances
beyond their control, such as complications related to COVID‑19, labor issues, political unrest or natural disasters.

Any supply chain deficiencies could materially and adversely affect our ability to fulfill customer orders and our results of operations. The availability of
critical components and materials from sole‑ or limited source suppliers could reduce our control over pricing, quality and timely delivery, increase our
costs, could disrupt our ability to manufacture and sell, and preclude us from manufacturing and selling, certain of our products into one or more markets.
Any such event could have a material adverse effect on our results of operations, cash flow and business.

Our ability to grow our business will be limited if we fail to maintain existing distribution channels or develop new distribution channels.

We collaborate with laboratories, diagnostic companies and distributors in order to sell our products. The sale of our products depends in large part on our
ability to sell products to these customers and on the marketing and distribution abilities of the companies with which we collaborate and work with.

Relying on distributors or third parties to market and sell our products could negatively impact our business for various reasons, including: (1) we may not
be able to find suitable distributors for our products on satisfactory terms, or at all; (2) agreements with distributors may prematurely terminate or may
result in litigation between the parties; (3) our distributors or other customers may not fulfill their contractual obligations and distribute our products in the
manner  or  at  the  levels  we  expect;  (4)  our  distributors  may  prioritize  their  own  private  label  products  that  compete  with  our  products;  (5)  our  existing
distributor  relationships  or  contracts  may  preclude  or  limit  us  from  entering  into  arrangements  with  other  distributors;  and  (6)  we  may  not  be  able  to
negotiate new or renew existing distribution agreements on acceptable terms, or at all.

We  will  try  to  maintain  and  expand  our  business  with  distributors  and  customers  and  make  every  effort  to  require  that  they  fulfill  their  contractual
obligations, but there can be no assurance that such companies will do so or that new distribution channels will be available on satisfactory terms. If we are
unable to do so, our business will be negatively impacted.

Our U.S. government contracts require compliance with numerous laws and increase our risk and liability.

We are currently receiving funding from the U.S. government related to the DPP SARS-CoV-2 Antigen System, the DPP Respiratory Antigen Panel and
DPP Zika, and our growth strategy may target sales to U.S. government entities. As a result of our U.S. government funding and potential product sales to
the U.S. government, we must comply with laws and regulations relating to the award, administration and performance of U.S. government contracts. U.S.
government contracts typically contain a number of extraordinary provisions that would not typically be found in commercial contracts and which may
create a disadvantage and additional risks to us as compared to competitors that do not rely on government contracts. As a U.S. government contractor, we
are subject to increased risks of investigation, criminal prosecution and other legal actions and liabilities to which purely private sector companies are not.
The results of any such actions could adversely impact our business and have an adverse effect on our consolidated financial performance.

A violation of specific laws and regulations could result in the imposition of fines and penalties or the termination of our contracts, as well as suspension or
debarment. The suspension or debarment in any particular case may be limited to the facility, contract or subsidiary involved in the violation or could be
applied to our entire enterprise in certain severe circumstances. Even a narrow scope suspension or debarment could result in negative publicity that could
adversely affect our ability to renew contracts and to secure new contracts, both with the U.S. government and private customers, which could materially
and adversely affect our business and results of operations. Fines and penalties could be imposed for failing to follow procurement integrity and bidding
rules, employing improper billing practices or otherwise failing to follow rules relating to billing on cost‑plus contracts, receiving or paying kickbacks, or
filing false claims, among other potential violations. In addition, we could suffer serious reputational harm and the value of our common stock could be
negatively affected if allegations of impropriety related to such contracts are made against us.

Our  U.S.  government  contracts  are  subject  to  future  funding  and  the  government’s  choice  to  exercise  options,  and  may  be  terminated  at  the
government’s convenience.

Our contracts with the U.S. government are subject to future funding and are subject to the right of the government to terminate the contracts in whole or in
part  for  its  convenience.  There  is  pressure  for  the  U.S.  government  to  reduce  spending.  The  non‑appropriation  of  funds  or  the  termination  for  the
government’s convenience of our contracts could negatively affect our financial results. If levels of U.S. government expenditures and authorizations for
emerging  diseases  decrease  or  shift  to  programs  in  areas  where  we  do  not  offer  products  or  are  not  developing  product  candidates,  or  if  the  U.S.
government otherwise declines to exercise its options under its contracts with us, our business, revenues and other operating results would suffer.

Risks Related to Regulations

COVID‑19 diagnostic tests, including the COVID-19 Diagnostic Test Systems, are subject to changes in CLIA, FDA, ANVISA and other regulatory
requirements.

Our  COVID-19  Diagnostic  Test  Systems  are  subject  to  regulations  of  the  FDA  and  other  regulatory  requirements,  including  ANVISA,  Brazil’s  health
regulatory agency. The regulations regarding the manufacture and sale of COVID-19 Diagnostic Test Systems may be unclear and are subject to recurring
change.  Newly  promulgated  regulations  could  require  changes  to  COVID-19  Diagnostic  Test  Systems,  necessitate  additional  procedures,  or  make  it
impractical or impossible for us to market COVID-19 Diagnostic Test Systems for certain uses, in certain markets, or at all. The FDA and other regulatory
authorities also have the ability to impose new or additional requirements relating to the COVID-19 Diagnostic Test Systems. The implementation of such
changes or new or additional requirements may result in a substantial additional costs and could delay or make it more difficult or complicated to sell our
products.

On February 4, 2020, the U.S. Department of Health and Human Services issued a declaration that the threat to public health posed by COVID-19 justify
the emergency use of unapproved in vitro diagnostics for the detection or diagnosis of SARS-CoV-2. Under Section 564 of the Food, Drug, and Cosmetic
Act, because the U.S. Department of Health and Human Services has issued this declaration, the Commissioner of the FDA is authorized to issue EUAs to
permit certain developers of SARS-CoV-2 diagnostics to begin offering the tests for detection and diagnosis of COVID-19 without having completed the
normally applicable FDA review and clearance or approval process for marketing authorization. We received an EUA for the DPP  COVID-19 IgM/IgG
System on April 14, 2020, which was subsequent revoked by the FDA on June 16, 2020. Such revocation precludes the sale of DPP COVID-19 IgM/IgG
Systems in the United States unless and until a further regulatory approval or authorization is obtained. We have not received a subsequent EUA for any of
the  COVID-19  Diagnostic  Test  Systems,  and  we  do  not  currently  have  an  application  pending  for  any  such  EUA.  Moreover,  market  and  regulatory
requirements  continue  to  change  at  a  rapid  pace.  The  FDA  has  announced,  for  example,  that  it  intends  to  update  its  EUA  templates  with  additional
considerations related to the impact of genetic variants on test performance as the FDA learns more about the COVID-19 disease and its knowledge in this
area progresses. The time required to obtain marketing authorizations and other approvals from regulatory authorities is unpredictable. The standards that
the FDA and its foreign counterparts use when evaluating clinical trial data can change, and do often change, during development, which makes it difficult
to predict with any certainty how they will be applied. If we make future submissions to the FDA, we may also encounter unexpected delays or increased
costs  due  to  new  government  regulations,  including  future  legislation  or  administrative  action,  or  changes  in  FDA  policy  during  the  period  of  FDA
regulatory review. There can be no assurance that if we are to make a submission of any future EUA application, we will be successful in obtaining an
EUA that would permit us to offer and sell any COVID-19 Diagnostic Test System in the United States.

We are subject to governmental export controls that could impair our ability to compete in international markets.

The  U.S.  and  various  foreign  governments  have  imposed  controls,  export  license  requirements  and  restrictions  on  the  export  of  certain  products  and
technologies.  We  must  export  our  products  in  compliance  with  export  controls  in  the  United  States,  including  the  Commerce  Department’s  Export
Administration Regulations and various economic and trade sanctions established by the Treasury Department’s Office of Foreign Assets Controls. We may
not always be successful in obtaining necessary export licenses, and our failure to obtain required import or export approval for our products or limitations
on  our  ability  to  export  or  sell  our  products  imposed  by  these  laws  may  harm  our  international  and  domestic  sales  and  adversely  affect  our  revenue.
Noncompliance with these laws could have negative consequences, including government investigations, penalties and reputational harm.

If the U.S. government imposes restrictions on the export of COVID-19 Diagnostic Test Systems, or any of our other products, such restrictions could have
a  material  impact  on  our  ability  to  sell  our  products  to  existing  or  potential  customers  outside  of  the  United  States  and  harm  our  ability  to  compete
internationally. Any change in export regulations or legislation, or change in the countries, persons or technologies targeted by export regulations, could
decrease our ability to export or sell our products outside the United States or to existing or potential customers with international operations. Changes in
our ability to sell our products outside the United States could negatively impact our business prospects and adversely affect our business and results of
operations.

Because we may not be able to obtain or maintain the necessary regulatory approvals for some of our products, we may not generate revenues in the
amounts  we  expect,  or  in  the  amounts  necessary  to  continue  our  business.  Our  existing  products  as  well  as  our  manufacturing  facility  must  meet
quality standards and are subject to inspection by a number of domestic regulatory and other governmental and non‑governmental agencies.

All  of  our  proposed  and  existing  products  are  subject  to  regulation  in  the  United  States  by  the  FDA,  the  U.S.  Department  of  Agriculture,  and/or  other
domestic and international governmental, public health agencies, regulatory bodies or non-governmental organizations. In particular, we are subject to strict
governmental controls on the development, manufacture, labeling, distribution and marketing of our products. The process of obtaining required approvals
or clearances varies according to the nature of, and uses for, a specific product. These processes can involve lengthy and detailed laboratory testing, human
or animal clinical trials, sampling activities, and other costly, time consuming procedures. The submission of an application to a regulatory authority does
not guarantee that the authority will grant an approval or clearance for that product. Each authority may impose its own requirements and can delay or
refuse to grant approval or clearance, even though a product has been approved in another country.

The time taken to obtain approval or clearance varies depending on the nature of the application and may result in the passage of a significant period of
time from the date of submission of the application. As an example, the time required to obtain an EUA from the FDA for COVID‑19 tests has lengthened
markedly over the past months due to, among other things, application volume. Delays in the approval or clearance processes increase the risk that we will
not succeed in introducing or selling the subject products, and we may determine to devote our resources to different products.

Changes or developments in government regulations, policies or interpretations could increase our costs and could require us to undergo additional trials or
procedures, or could make it impractical or impossible for us to market our products for certain uses, in certain markets, or at all. For example, on June 16,
2020, the FDA revoked the EUA it had granted for the DPP COVID-19 IgM/IgG System based in part on performance criteria identified after the EUA
was  granted  on  April  14,  2020.  We  do  not  currently  have  an  EUA  from  the  FDA  for  any  of  the  COVID-19  Diagnostic  Test  Systems,  and  we  do  not
currently  have  an  application  pending  for  any  such  EUA.  Moreover,  FDA  regulations,  policies  and  procedures  with  respect  to  COVID-19 tests may be
significantly impacted by the availability of vaccines for COVID-19 and changes in the FDA’s prioritization guidance. Similarly, the regulatory pathway to
510(k) clearance by the FDA for COVID-19 tests is unclear in light of limited FDA feedback resulting in part from the FDA’s constrained resources.

Changes  in  government  regulations  may  adversely  affect  our  financial  condition  and  results  of  operations  because  we  may  have  to  incur  additional
expenses if we are required to change or implement new testing, manufacturing and control procedures. If we are required to devote resources to develop
such new procedures, we may not have sufficient resources to devote to research and development, marketing, or other activities that are critical to our
business.  We  are,  for  example,  expending  resources  to  modify  the  design  of  the  COVID-19  Diagnostic  Test  System  to  achieve  performance  targets
consistent with the FDA’s performance criteria issued subsequent to the granting of our original EUA.

We can manufacture and sell our products only if we comply with regulations and quality standards established by government agencies such as the FDA
and the U.S. Department of Agriculture as well as by non-governmental organizations such as the International Organization for Standardization, or ISO,
and WHO. We have implemented a quality control system that is intended to comply with applicable regulations. Although FDA approval is not required
for  the  export  of  our  products,  there  are  export  regulations  promulgated  by  the  FDA  that  specifically  relate  to  the  export  of  our  products  that  require
compliance with the FDA’s quality system requirements, or QSRs, and that also require meeting certain documentary requirements regarding the approval
of  the  product  in  export  markets.  We  also  may  be  subject  to  import  regulations  in  connection  with  international  sourcing  of  components  and  materials
incorporated in the manufacturing of our products.

If we do not comply with FDA or other regulatory requirements, we may be required to suspend production or sale of our products or institute a recall,
which could result in higher costs and a loss of revenues.

Regulations  of  the  FDA  and  other  federal,  state  and  foreign  regulatory  agencies  have  significant  effects  on  many  aspects  of  our  operations  and  the
operations  of  our  suppliers  and  distributors,  including  packaging,  labeling,  manufacturing,  adverse  event  reporting,  recalls,  distribution,  storage,
advertising,  promotion  and  record  keeping.  We  are  subject  to  routine  inspection  by  the  FDA  and  other  agencies  to  determine  compliance  with  FDA
regulatory requirements, including QSRs, in the United States and other applicable regulations worldwide, including ISO standards. We believe that our
facilities and procedures are in material compliance with the FDA requirements and ISO standards, but the regulations may be unclear and are subject to
change, and we cannot be sure that the FDA or other regulators will agree with our compliance with these requirements. The FDA and foreign regulatory
agencies  may  require  post  marketing  testing  and  surveillance  to  monitor  the  performance  of  approved  or  cleared  products  or  impose  conditions  on  any
product  clearances  or  approvals  that  could  restrict  the  distribution  or  commercial  applications  of  those  products.  Regulatory  agencies  may  impose
restrictions on our or our distributors’ advertising and promotional activities or preclude these activities altogether if a noncompliance is believed to exist.
In addition, the subsequent discovery of previously unknown problems with a product may result in restrictions on  the  product  or  additional  regulatory
actions, including withdrawal of the product from the market.

Our  inability  to  comply  with  the  applicable  requirements  of  the  FDA  can  result  in,  among  other  things,  483  notices,  warning  letters,  administrative  or
judicially imposed sanctions such as injunctions, recall or seizure of products, civil penalties, withdrawal of product registrations, total or partial suspension
of  production,  refusal  to  grant  premarket  clearance  for  devices,  a  determination  that  a  device  is  not  approvable,  marketing  clearances  or  approvals,  or
criminal  prosecution.  For  example,  in  February  2020,  we  received  a  “not  approvable”  letter  from  the  FDA  with  respect  to  our  premarket  approval
submission on our DPP HIV Syphilis multiplex test for commercial use in the United States, in June 2020 we received notice from the FDA that the EUA
for the DPP COVID-19 IgM/IgG System had been revoked, and in January 2021 we received notice from the FDA that it was declining to review the DPP
SARS CoV 2 Antigen System based on its updated prioritization guidance, under which review of the system was not a priority. The ability of our suppliers
to supply critical components or materials and of our distributors to sell our products could also be adversely affected if their operations are determined to
be out of compliance. Such actions by the FDA and other regulatory bodies could adversely affect our revenues, costs and results of operations.

We must frequently make judgment decisions with respect to compliance with applicable laws and regulations. If regulators subsequently disagree with
how we have sought to comply with these regulations, we could be subjected to substantial civil and criminal penalties, as well as product recall, seizure or
injunction with respect to the sale of our products. Our reputation could be substantially impaired if we are assessed any civil and criminal penalties and
limit our ability to manufacture and market our products which could have a material adverse effect on our business.

Our inability to respond to changes in regulatory requirements could adversely affect our business.

We  believe  that  our  existing  products  and  procedures  are  in  material  compliance  with  all  applicable  FDA  regulations,  ISO  requirements,  and  other
applicable regulatory requirements, but the regulations regarding the manufacture and sale of our products and QSR, ISO and other requirements may be
unclear and are subject to change. Newly promulgated regulations could require changes to our products, necessitate additional clinical trials or procedures,
or make it impractical or impossible for us to market our products for certain uses, in certain markets, or at all. The FDA and other regulatory authorities
also  have  the  ability  to  change  the  requirements  for  obtaining  product  approval  and/or  impose  new  or  additional  requirements  as  part  of  the  approval
process.  These  changes  or  new  or  additional  requirements  may  occur  after  the  completion  of  substantial  clinical  work  and  other  costly  development
activities. The implementation of such changes or new or additional requirements may result in additional clinical trials and substantial additional costs and
could  delay  or  make  it  more  difficult  or  complicated  to  obtain  approvals  and  sell  our  products.  In  addition,  the  FDA  may  revoke  an  Emergency  Use
Authorization  under  which  our  products  are  sold,  where  it  is  determined  that  the  underlying  health  emergency  no  longer  exists  or  warrants  such
authorization. Such revocation would preclude the sale of our affected products unless and until a further regulatory approval or authorization is obtained.
For  example,  For  example,  on  June  16,  2020,  the  FDA  revoked  the  EUA  it  had  granted  for  the  DPP  COVID‑19  IgM/IgG  System  based  in  part  on
performance criteria identified after the Emergency Use Authorization was granted on April 14, 2020, and since that time we expended resources to design
the new COVID-19 Diagnostic Test Systems, including the DPP Respiratory Antigen Panel. We do not currently have an EUA from the FDA for any of the
COVID-19 Diagnostic Test Systems, and we do not currently have an application pending for any such EUA We cannot anticipate or predict the effect, if
any, that these types of changes might have on our business, financial condition or results of operations.

Demand for our products may be affected by FDA regulation of laboratory developed tests.

Regulatory responsibility over instruments, test kits, reagents and other devices used to perform diagnostic testing by clinical laboratories is covered by the
FDA, including our Micro Reader analyzer. The FDA has previously taken the position that it has regulatory authority over laboratory developed tests, or
LDTs, but has exercised enforcement discretion by not regulating most LDTs performed by high complexity CLIA certified laboratories. LDTs are tests
designed, developed, and performed in house by a laboratory. These laboratories are subject to CLIA regulation but such laboratories have previously not
been subject to regulation by the FDA under the agency’s medical device requirements.

The FDA announced that it would begin regulating LDTs, and in October 2014 the FDA issued proposed guidance on the regulation of LDTs for public
comment. In November 2016, however, the FDA announced it would not finalize the proposed guidance prior to the end of the Obama administration. In
January 2017 the FDA released a discussion paper synthesizing public comments on the 2014 draft guidance documents and outlining a possible approach
to regulation of LDTs. The discussion paper has no legal status and does not represent a final version of the LDT draft guidance documents. We cannot
predict what policies the Biden administration will adopt with respect to LDTs. If the FDA increases regulation of LDTs, it could make it more difficult for
laboratories  and  other  customers  to  continue  offering  LDTs  that  involve  molecular  testing.  This,  in  turn,  could  reduce  demand  for  our  products  and
adversely impact our revenues.

Disruptions at the FDA and other government agencies caused by funding shortages or global health concerns could hinder their ability to hire, retain
or deploy key leadership and other personnel, or otherwise prevent new or modified products from being developed, cleared, approved, authorized, or
commercialized in a timely manner or at all, which could negatively impact our business.

The ability of the FDA and other government agencies to review and clear, approve, or authorize new products can be affected by a variety of factors,
including government budget and funding levels, statutory, regulatory, and policy changes, the agencies’ ability to hire and retain key personnel and accept
the  payment  of  user  fees,  and  other  events  that  may  otherwise  affect  the  agencies’  ability  to  perform  routine  functions.  Average  review  times  at  these
agencies have fluctuated in recent  years  as  a  result.  In  addition,  government  funding  of  other  government  agencies  that  fund  research  and  development
activities is subject to the political process, which is inherently fluid and unpredictable. Disruptions at the FDA and other agencies may also slow the time
necessary  for  medical  devices  or  modifications  to  be  cleared  or  approved,  medical  devices  to  be  reviewed  and/or  approved  by  necessary  government
agencies, which would adversely affect our business. For example, over the last several years, including for 35 days beginning on December 22, 2018, the
U.S. government has shut down several times and certain regulatory agencies, such as the FDA, have had to furlough critical FDA employees and stop
critical activities.

Separately, in response to the global COVID-19 pandemic, on January 29, 2021, the FDA announced its intention to resume inspections of manufacturing
facilities and products, that would be deemed “mission-critical.” The FDA’s assessment of whether an inspection is mission-critical considers many factors
related to the public health benefit of U.S. patients having access to the product subject to inspection. These factors include, but are not limited to, whether
the products have received  breakthrough  therapy  designation  or  regenerative  medicine  advanced  therapy  designation,  or  are  products  used  to  diagnose,
treat, or prevent a serious disease or medical condition for which there is no other appropriate substitute. Both for-cause and pre-approval inspections can
be deemed mission-critical. When determining whether to conduct a mission-critical inspection, FDA takes into account concerns about the safety of its
investigators, employees at a site or facility, and where applicable, clinical trial participants and other patients at investigator sites. Regulatory authorities
outside  the  United  States  may  adopt  similar  restrictions  or  other  policy  measures  in  response  to  the  COVID-19  pandemic.  If  a  prolonged  government
shutdown  occurs,  or  if  global  health  concerns  continue  to  prevent  the  FDA  or  other  regulatory  authorities  from  conducting  their  regular  inspections,
reviews or other regulatory activities, it could significantly impact the ability of the FDA or other regulatory authorities to timely review and process our
regulatory submissions, which could have a material adverse effect on our business.

Table of Contents

In addition to FDA requirements, we are subject to numerous other federal, state and foreign government regulations, compliance with which could
increase our costs and affect our operations.

In addition to the FDA regulations previously described, other federal, state and foreign laws and regulations may restrict our ability to sell products in
those jurisdictions.

We must comply with numerous laws related to safe working conditions, environmental protection, disposal of hazardous substances, fire hazard control,
manufacturing practices and labor or employment practices. Compliance with these laws or any new or changed laws regulating our business could result
in substantial costs. Due to the number of laws and regulations governing our industry, and the actions of a number of government agencies that could
affect our operations, it is impossible to reliably predict the full nature and impact of these laws and regulations. To the extent the costs and procedures
associated  with  complying  with  these  laws  and  requirements  are  substantial  or  it  is  determined  that  we  do  not  comply,  our  business  and  results  of
operations could be adversely affected.

Ongoing changes in healthcare regulation could negatively affect our revenues, business and financial condition.

There  have  been  several  proposed  changes  in  the  United  States  at  the  federal  and  state  level  for  comprehensive  reforms  regarding  the  payment  for,  the
availability  of  and  reimbursement  for  healthcare  services.  These  proposals  have  ranged  from  fundamentally  changing  federal  and  state  healthcare
reimbursement  programs,  including  providing  comprehensive  healthcare  coverage  to  the  public  under  government‑funded  programs,  to  minor
modifications to existing programs. One example is the Patient Protection and Affordable Care or the Affordable Care Act, the Federal healthcare reform
law enacted in 2010.

Healthcare reform initiatives will continue to be proposed, and may reduce healthcare related funding in an effort. It is impossible to predict the ultimate
content and timing of any healthcare reform legislation and its resulting impact on us. If significant reforms are made to the healthcare system in the United
States, or in other jurisdictions, those reforms may increase our costs or otherwise negatively effect on our financial condition and results of operations.

The EU landscape concerning medical devices recently evolved. On May 25, 2017, the E.U. Medical Devices Regulation entered into force, which repeals
and replaces the Council Directive 93/42/EEC, or E.U. Medical Devices Directive, and Directive 90/385/EEC, or AIMDD. Unlike directives, which must
be implemented into the national laws of the EU member states, regulations are directly applicable (i.e., without the need for adoption of E.U. member state
laws implementing them) in  all  E.U.  member  states  and  are  intended  to  eliminate  current  differences  in  the  regulation  of  medical  devices  among  E.U.
member states. Devices lawfully placed on the market pursuant to the E.U. Medical Devices Directive or the AIMDD prior to May 26, 2021 may generally
continue  to  be  made  available  on  the  market  or  put  into  service  until  May  26,  2025,  provided  that  the  requirements  of  the  transitional  provisions  are
fulfilled.  In  particular,  the  certificate  in  question  must  still  be  valid.  However,  even  in  this  case,  manufacturers  must  comply  with  a  number  of  new  or
reinforced requirements set forth in the E.U. Medical Devices Regulation with regard to registration of economic operators and of devices, post-market
surveillance, market surveillance and vigilance requirements.

Subject  to  the  transitional  provisions,  in  order  to  sell  our  products  in  E.U.  member  states,  our  products  must  comply  with  the  general  safety  and
performance  requirements  of  the  E.U.  Medical  Devices  Regulation,  which  repeals  and  replaces  EU  Medical  Devices  Directive  and  the  AIMDD.
Compliance with these requirements is a prerequisite to be able to affix the CE mark to our products, without which they cannot be sold or marketed in the
EU. To demonstrate compliance with the general safety and performance requirements, we must undergo a conformity assessment procedure, which varies
according to the type of medical device and its (risk) classification. Except for low risk medical devices (Class I), where the manufacturer can self-assess
the  conformity  of  its  products  with  the  general  safety  and  performance  requirements  (except  for  any  parts  which  relate  to  sterility,  metrology  or  reuse
aspects), a conformity assessment procedure requires the intervention of a notified body. The notified body would typically audit and examine the technical
file and the quality system for the manufacture, design and final inspection of our devices. If satisfied that the relevant product conforms to the relevant
general  safety  and  performance  requirements,  the  notified  body  issues  a  certificate  of  conformity,  which  the  manufacturer  uses  as  a  basis  for  its  own
declaration of conformity. The manufacturer may then apply the CE mark to the device, which allows the device to be placed on the market throughout the
E.U. If we fail to comply with applicable laws and regulations, we would be unable to affix the CE mark to our products, which would prevent us from
selling them within the E.U.

46

Table of Contents

We must inform the notified body that carried out the conformity assessment of the medical devices that we market or sell in the E.U. and the EEA of any
planned substantial changes to our quality system or substantial changes to our medical devices that could affect compliance with the general safety and
performance requirements laid down in Annex I to the E.U. Medical Devices Regulation or cause a substantial change to the intended use for which the
device has been CE marked. The notified body will then assess the planned changes and verify whether they affect the products’ ongoing conformity with
the E.U. Medical Devices Regulation. If the assessment is favorable, the notified body will issue a new certificate of conformity or an addendum to the
existing certificate attesting compliance with the general safety and performance requirements and quality system requirements laid down in the Annexes to
the E.U. Medical Devices Regulation.

We may incur additional costs if we do not comply with privacy, security and breach notification regulations.

We believe that we are not a covered entity nor a business associate of a covered entity and are not responsible for complying with the Health Insurance
Portability and Accountability Act of 1996, or HIPAA. Even though we likely are not a covered entity under HIPAA, we do have in place administrative,
technical and physical safeguards to protect the privacy and security of consumers’ personal information. We are required to comply with varying state
privacy, security and breach reporting laws. If we fail to comply with existing or new laws and regulations related to properly transferring data containing
consumers’ personal information, we could be subject to monetary fines, civil penalties or criminal sanctions. Also, there are other federal and state laws
that protect the privacy and security of consumers’ personal information, and we may be subject to enforcement by various governmental authorities and
courts resulting in complex compliance issues. We could incur damages under state laws pursuant to an action brought by a private party for the wrongful
use or disclosure of consumers’ personal information.

Failure to comply with European and U.K. data protection requirements could increase our costs.

The E.U. adopted a comprehensive overhaul of its data protection regime from the prior national legislative approach to a single European Economic Area
Privacy Regulation called the General Data Protection Regulation, or GDPR, which came into effect on May 25, 2018. The E.U. data protection regime
extends the scope of the E.U. data protection law to all foreign companies processing data of E.U. residents. It imposes a strict data protection compliance
regime with severe penalties of up to the greater of 4% of worldwide turnover and €20 million and includes new rights such as the “portability” of personal
data. Although the GDPR applies across the E.U. without a need for local implementing legislation, as had been the case under the prior data protection
regime, local data protection authorities have the ability to interpret the GDPR, which has the potential to create inconsistencies on a country‑by‑country
basis. We have evaluated these new requirements and have implemented a plan to ensure compliance. Complying with the enhanced obligations imposed
by the GDPR may result in significant costs to our business and require us to amend certain of our business practices. Further, we have no assurances that
violations  will  not  occur,  particularly  given  the  complexity  of  the  GDPR,  as  well  as  the  uncertainties  that  accompany  new,  comprehensive  legislation.
Further, from January 1, 2021, we have to comply with both the GDPR and the GDPR as incorporated into United Kingdom national law, the latter regime
having the ability to separately fine up to the greater of £17.5 million or 4% of global turnover. The relationship between the United Kingdom and the EU
in relation to certain aspects of data protection law remains unclear, for example around how data can lawfully be transferred between each jurisdiction,
which may expose us to further compliance risk. The European Commission has adopted an adequacy decision in favor of the UK, enabling data transfers
from EU member states to the UK without additional safeguards. However, the UK adequacy decision will automatically expire in June 2025 unless the
European Commission re-assesses and renews/ extends that decision.

If we are not able to manufacture products in accordance with applicable requirements, it could adversely affect our business.

Our products must meet detailed specifications, performance standards and quality requirements. As a result, our products and the materials used in their
manufacture  or  assembly  undergo  regular  inspections  and  quality  testing.  Factors  such  as  defective  materials  or  processes,  mechanical  failures,  human
errors, environmental conditions, changes in materials or production methods, and other events or conditions could cause our products or the materials used
to produce or assemble our products to fail inspections and quality testing or otherwise not perform in accordance with our label claims or the expectations
of our customers.

If we are not able to meet the applicable specifications, performance standards, quality requirements or customer expectations could adversely affect our
ability to manufacture and sell our products or comply with regulatory requirements. These events could, in turn, adversely affect our revenues and results
of operations.

Healthcare fraud and abuse laws could adversely affect our business and results of operations.

There are various federal and state laws targeting fraud and abuse in the healthcare industry to which we are subject, including anti‑kickback laws, laws
constraining the sales, false claims laws, marketing and promotion of medical devices by limiting the kinds of financial arrangements that manufacturers of
these products may enter into with physicians, hospitals, laboratories and other potential purchasers of medical devices. There are other laws we are subject
to  that  require  us  to  report  certain  transactions  between  it  and  healthcare  professionals.  Violations  of  these  laws  are  punishable  by  criminal  or  civil
sanctions,  including  substantial  fines,  imprisonment  and  exclusion  from  participation  in  government  healthcare  programs.  Many  of  the  existing
requirements are new and have not been definitively interpreted by state authorities or courts, and available guidance is limited. We could face enforcement
action and fines and other penalties, and could receive adverse publicity, unless and until we are in full compliance with these laws, all of which could
materially harm us. Furthermore, changes in or evolving interpretations of these laws, regulations, or administrative or judicial interpretations, may require
us  to  change  our  business  practices  or  subject  our  business  practices  to  legal  challenges,  which  could  have  a  material  adverse  effect  on  our  business,
financial condition and results of operations.

If we expand our international presence, it may increase our risks and expose our business to regulatory, cultural or other challenges.

There are several of factors that could adversely affect the performance of our business and/or cause us to incur substantially increased costs because of our
international presence and sales, including: (1) uncertainty in the application of foreign laws and the interpretation of contracts with foreign parties; (2)
cultural  and  political  differences  that  favor  local  competitors  or  make  it  difficult  to  effectively  market,  sell  and  gain  acceptance  of  our  products;  (3)
exchange rates, currency fluctuations, tariffs and other barriers, extended payment terms and dependence on international distributors or representatives; (4)
trade  protection  measures,  trade  sanctions  and  import/export  licensing  requirements;  (5)  our  inability  to  obtain  or  maintain  regulatory  approvals  or
registrations for our products; (6) economic conditions, political instability, the absence of available funding sources, terrorism, civil unrest, war and natural
disasters in foreign countries; (7) reduced protection for, or enforcement of, our patents and other intellectual property rights in foreign countries; (8) our
inability  to  identify  international  distributors  and  negotiate  acceptable  terms  for  distribution  agreements;  and  (9)  restrictions  on  our  ability  to  repatriate
investments and earnings from foreign operations.

Economic, cultural and political conditions and foreign regulatory requirements may slow or prevent the manufacture of our products in countries other
than the United States. Interruption of the supply of our products could reduce revenues or cause us to incur significant additional expenses in finding an
alternative source of supply. Foreign currency fluctuations and economic conditions in foreign countries could also increase the costs of manufacturing our
products in foreign countries.

Risks Related to Ownership of Common Stock

Our common stock may have limited liquidity, and investors may not be able to sell as much common stock as they want at prevailing market prices or
at all.

The liquidity of our common stock depends on several factors, including our financial results and overall market conditions, so it is not possible to predict
whether this level of liquidity will continue, be sustained, or decrease. Decreased trading volume in our stock would make it more difficult for investors to
sell their shares in the public market at any given time at prevailing prices. Our management and larger stockholders exercise significant control over our
company.

48

Table of Contents

Decreased trading volume in our stock would make it more difficult for investors to sell their shares in the public market at any given time at prevailing
prices. Although there is no affiliation between our management and our larger stockholders, they could exercise significant control over our company if
they voted their shares in a similar manner.

The price of our common stock could continue to be volatile, and existing stockholders’ investments in our common stock could lose value.

The price of our common stock has been volatile, subject to rapid and substantial decreases in stock price, and may be volatile in the future. By way of
example, during the year ended December 31, 2021, our common stock has traded at a low of  $1.09  and  a  high  of  $7.97.  As  a  result  of  this  volatility,
investors could experience losses on their investment in our common stock.

The stock market is subject to significant price and volume fluctuations, and the price of our common stock could fluctuate widely in response to several
factors,  including,  but  not  limited  to:  our  cash  flows  and  cash  position;  the  duration  and  severity  of  the  COVID-19  pandemic;  our  quarterly  or  annual
operating  results;  investment  recommendations  by  securities  analysts  following  our  business  or  our  industry;  additions  or  departures  of  key  personnel;
changes in our business, earnings  estimates  or  market  perceptions  of  our  competitors;  our  failure  to  achieve  operating  results  consistent  with  securities
analysts’ projections; changes in industry, general market or economic conditions; and announcements of legislative or regulatory change.

Overall, the stock market has experienced price and volume fluctuations that have affected the market price of our common stock, as well as the stock of
many  other  similar  companies.  Such  price  fluctuations  are  generally  unrelated  to  the  operating  performance  of  the  specific  companies  whose  stock  is
affected.

Since the stock price of our common stock has fluctuated in the past, has been recently volatile and may be volatile in the future, investors in our common
stock  could  incur  substantial  losses.  In  the  past,  following  periods  of  volatility  in  the  market,  securities  class-action  litigation  has  often  been  instituted
against companies. Such litigation, if instituted against us, could result in substantial costs and diversion of management’s attention and resources, which
could materially and adversely affect our business, financial condition, results of operations and growth prospects. We are currently subject to securities
class-action litigation as described in “—Legal Matters—Legal Proceedings” above. There can be no guarantee that our stock price will remain at current
levels.

Securities of certain companies have recently experienced significant and extreme volatility in stock price due to short sellers of shares of common stock,
known as a “short squeeze.” Short squeezes have caused extreme volatility in those companies and in the market and have led to the price per share of
those companies to trade at a significantly inflated rate that is disconnected from the underlying value of the company. Sharp rises in a company’s stock
price may force traders in a short position to buy the stock to avoid even greater losses. Many investors who have purchased shares in those companies at
an inflated rate face the risk of losing a significant portion of their original investment as the price per share has declined steadily as interest in those stocks
have abated. There can be no assurance that we will not, in the future be, a target of a short squeeze, and stockholders may lose a significant portion or all
of their investments if they purchase our shares at a rate that is significantly disconnected from our underlying value.

Our  stock  price  may  in  the  future  not  meet  the  minimum  bid  price  for  continued  listing  on  the  Nasdaq  Capital  Market.  Our  ability  to  publicly  or
privately sell equity securities and the liquidity of our common stock could be adversely affected if we are delisted from The Nasdaq Capital Market.

Nasdaq Listing Rule 5450(a)(1), which we refer to as the Minimum Bid Price Rule, provides that the closing bid price for our common stock may not be
below $1.00 per share for any period of 30 consecutive trading days to maintain our continued listing on The Nasdaq Capital Market. As of March 1, 2022,
the  closing  bid  price  for  our  common  stock  was  $0.97.  Although  we  are  currently  in  compliance  with  the  Minimum  Bid  Price  Rule,  there  can  be  no
assurance that our common stock will continue to satisfy this rule. If we were to fail to comply with the Minimum Bid Price Rule in the future and became
subject to delisting, such delisting from Nasdaq would adversely affect our ability to raise additional financing through the public or private sale of equity
securities, would significantly affect the ability of investors to trade our securities and would negatively affect the value and liquidity of our common stock.
Delisting also could have other negative results, including the potential loss of confidence by employees, the loss of institutional investor interest and fewer
business development opportunities.

Our common stock may become the target of a “short squeeze.”

Securities of certain companies have increasingly experienced significant and extreme volatility in stock price due to short sellers of shares of common
stock, known as a “short squeeze.” Short squeezes have caused extreme volatility in those companies and in the market and have led to the price per share
of those companies to trade at a significantly inflated rate that is disconnected from the underlying value of the company. Sharp rises in a company’s stock
price may force traders in a short position to buy the stock to avoid even greater losses. Many investors who have purchased shares in those companies at
an inflated rate face the risk of losing a significant portion of their original investment as the price per share has declined steadily as interest in those stocks
have abated. There can be no assurance that we will not, in the future be, a target of a short squeeze, and you may lose a significant portion or all of your
investment if you purchase our shares at a rate that is significantly disconnected from our underlying value.

You may experience future dilution as a result of future equity offerings, exercises of outstanding options and vesting of options and restricted and
performance stock units.

On July 19, 2021, we entered into the ATM Agreement, pursuant to which we may sell from time to time, at our option, up to an aggregate of $60,000,000
of  shares  of  common  stock  through  Craig-Hallum,  as  sales  agent.  As  of  the  filing  date  of  this  report,  we  have  issued  and  sold  pursuant  to  the  ATM
Agreement a total of 9,709,328 shares of common stock at a volume-weighted average price of $4.2011 per share for gross proceeds of $40.8 million and
net proceeds, after giving effect to placement fees and other transaction costs, of $38.8 million. For additional information about the at-the-market offerings
pursuant to the ATM Agreement, see “Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations”.

In order to raise additional capital, we may seek to offer pursuant to the ATM Agreement additional shares of common stock for up to $19.2 million in
gross proceeds and we may in the future offer additional shares of our common stock or other securities convertible into or exchangeable for our common
stock. There can be no assurance that we will be able to sell additional shares in at-the-market offerings made pursuant to the ATM Agreement, or in any
other offering, at a price per share that is equal to or greater than the price per share paid by existing stockholders. Investors purchasing securities in other
offerings in the future could have rights superior to existing stockholders.

As of the close of business on March 1, 2022, our market capitalization was approximately $29.2 million. Existing stockholders may experience significant
dilution in connection with our issuance and sale of up to $21.2 million of additional shares of common stock pursuant to the ATM Agreement. In addition,
as of December 31, 2021, 3,386,393 shares of common stock were reserved for future issuance under our 2019 Omnibus Incentive Plan, 1,600,372 shares
were subject to outstanding options, and 705,325 shares were subject to outstanding restricted and performance stock units. Stockholders will incur dilution
upon vesting of restricted and performance stock units, and they may incur dilution upon exercises of stock options.

Management will have broad discretion as to the use of any net proceeds of the offering made pursuant to the ATM Agreement, and we may not use
those net proceeds effectively.

Our management will have broad discretion in the application of the net proceeds of this offering made pursuant to the ATM Agreement and could spend
the proceeds in ways that do not improve our results of operations or enhance the value of our common stock. Our failure to apply these funds effectively
could have a material adverse effect on our business and could cause the price of our common stock to decline.

Any future issuances of shares of our common stock by us could harm the price of our common stock and our ability to raise funds in new equity
offerings.

Any future sales of a substantial number of our shares of common stock or other equity‑related securities, or the perception that such sales may occur, could
adversely affect the price of our common stock, and could impair our ability to raise capital through future offerings of equity or equity‑related securities.

50

 
Table of Contents

Sales of our common stock by existing stockholders, executive officers or directors could depress the market price of our common stock.

If  our  existing  stockholders,  officers  or  directors  sell  our  common  stock  in  the  public  market,  or  the  perception  that  such  sales  may  occur,  it  could
negatively affect the price of our common stock. We are unable to estimate the number of shares of our common stock that may actually be resold in the
public market since this will depend on the market price for our common stock, the individual circumstances of the sellers and other factors.

Institutional  stockholders  own  significant  amounts  of  our  common  stock.  If  one  or  more  of  these  stockholders  sell  large  portions  of  their  holdings  in  a
relatively short time, the prevailing price of our common stock could be negatively affected. In addition, it is possible that one or more of our executive
officers or non‑employee members of our Board of Directors could sell shares of our common stock during an open trading window. These transactions and
the perceived reasons for these transactions could have a negative effect on the prevailing market price of our common stock.

We do not intend to pay cash dividends on our common stock.

We  do  not  expect  to  pay  any  cash  dividends  on  our  common  stock  and  currently  intend  to  retain  our  earnings,  if  any,  to  finance  the  expansion  of  our
business. Therefore, the success of an investment in our common stock will depend entirely upon any future increase in value of our common stock. There
is no guarantee that our common stock will gain value or even maintain the price at which investors purchased their shares.

General Risk Factors

We may not generate the expected benefits of future strategic transactions or investments, and they could disrupt our ongoing business, distract our
management, increase our expenses and negatively affect our business.

As a way for us to grow our business, we may pursue strategic transactions or investments. These activities, and their impact on our business, are subject to
many risks, including the following: (1) the benefits expected to be derived from a transaction or investment may not materialize and could be affected by
numerous  factors,  such  as  regulatory  developments,  insurance  reimbursement,  our  inexperience  with  new  businesses  or  markets,  general  economic
conditions and increased competition; (2) we may be unable to successfully integrate with a partner company’s personnel, assets, management, information
technology  systems,  accounting  policies  and  practices,  products  and/or  technology  into  our  business;  (3)  we  may  not  be  able  to  accurately  forecast  the
performance  or  ultimate  impact  of  a  partner  business;  and  (4)  a  strategic  transaction  may  result  in  the  incurrence  of  unexpected  expenses,  stockholder
lawsuits, the dilution of our earnings or our existing stockholders’ percentage ownership, or potential losses from undiscovered liabilities not covered by an
indemnification from the seller(s) of the partner business.

If these factors occur, we may be unable to achieve all or a significant part of the benefits expected from a strategic transaction or investment. This may
adversely affect our financial condition, results of operations and ability to grow our business or otherwise achieve our financial and strategic objectives.

Our compliance with regulations governing public companies is complex and expensive.

Public companies are subject to various laws and regulations, which have increased the scope, complexity and cost of corporate governance, reporting and
disclosure practices. For example, we are subject to the Sarbanes‑Oxley Act of 2002, The Dodd‑Frank Wall Street Reform and Consumer Protection Act
and the requirements of the Nasdaq Capital Market. The implementation of certain aspects of these laws and regulations has required and will continue to
require substantial management time and oversight and may require us to incur significant additional accounting and legal costs. We continually review
changes with respect to new and proposed rules and cannot predict or estimate the amount of additional costs, and the timing of such costs, we may incur.
There are several interpretations of these laws and regulations, in many cases due to their lack of specificity, and as a result, their application in practice
may change as new guidance is provided by regulatory and governing bodies. This may result in continuing uncertainty regarding compliance matters and
higher costs. We are committed to maintaining high standards of corporate governance and public disclosure, but if we fail to comply with any of these
requirements, legal proceedings may be initiated against us, which may adversely affect our business.

Our business may be negatively affected by terrorist attacks or natural disasters.

Terrorist attacks or natural disasters could cause economic instability. These events could negatively affect economic conditions both within and outside the
United States and harm demand for our products. The operations of our customers and suppliers could be negatively impacted and eliminate, reduce or
delay our customers’ ability to purchase and use our products and our suppliers’ ability to provide raw materials and finished products.

Our  facilities,  including  some  pieces  of  manufacturing  equipment  and  our  computer  systems,  may  be  difficult  to  replace.  Various  types  of  disasters,
including fires, earthquakes, floods and acts of terrorism, may affect our facilities and computer systems. In the event our existing facilities or computer
systems are affected by man‑made or natural disasters, we may have difficulty operating our business and may be unable to manufacture products for sale
or meet customer demands or sales projections. If our manufacturing operations were curtailed or shut down entirely, it would seriously harm our business

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

We  develop  and  commercialize  point-of-care  diagnostic  tests  used  for  the  rapid  detection  and  diagnosis  of  infectious  diseases,  including  sexually
transmitted disease, insect vector and tropical disease, COVID-19 and other viral and bacterial infections, enabling expedited treatment.

Our product portfolio is based upon our proprietary DPP technology, a diagnostic platform that provides high-quality, cost-effective results in 15 to 20
minutes using fingertip blood, nasal swabs and other sample types. The DPP technology platform addresses the rapid diagnostic test market, which
includes infectious diseases, cardiac markers, cholesterol and lipids, pregnancy and fertility, and drugs of abuse. Compared with traditional lateral flow
technology, the DPP technology platform can provide enhanced sensitivity and specificity, advanced multiplexing capabilities and, with the DPP Micro
Reader, quantitative results.

We target the market for rapid diagnostic test solutions for infectious diseases, which is 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.  We  have  a  broad  portfolio  of  infectious
disease products, which prior to 2020 were focused principally on sexually transmitted disease and fever and tropical disease. In February 2020 we began
the  process  of  shifting  substantially  all  of  our  resources  to  seek  to  leverage  the  DPP  technology  platform  to  address  the  acute  and  escalating  need  for
diagnostic testing for COVID-19. We are continuing to pursue:

•

•
•

an emergency use authorization, or EUA, from the U.S. Food and Drug Administration, or FDA, as well as 510(k) clearance from the FDA, for
the DPP SARS-CoV-2 Antigen test system;
an EUA from the FDA for the DPP Respiratory Panel; and
a Clinical Laboratory Improvement Amendment, or CLIA, waiver from the FDA for the DPP HIV-Syphilis test system.

Our  products  are  sold  globally,  directly  and  through  distributors,  to  medical  laboratories  and  hospitals,  governmental  and  public  health  entities,
nongovernmental organizations, medical professionals, and retail establishments. We continue to seek to expand our commercial distribution channels.

Global Competitiveness Program

We  have  achieved  significant  revenue  growth  in  recent  years  while  profitability  has  not  been  at  levels  as  expected.  We  have  taken  steps  including
investments  in  automation  to  mitigate  headwinds  including  labor  availability,  volatile  capacity  planning  and  implementation  of  operational  efficiency
targets to proactively monitor production with the overarching goal for profitable growth. To further accelerate and aggressively execute towards this goal
to improve profitability, in the first quarter of 2022 we have initiated a Global Competitiveness Program. Our Global Competitiveness Program has been
developed with the support of the Company’s executive leadership team to ensure cross-functional alignment, commitment and accountability throughout
the organization. The main pillars of the Global Competitiveness Program include the following:

•

Focus on higher margin business in growth markets: Our pursuit of growth in markets with higher selling prices remains unchanged. We have
recently  completed  an  in-depth  analysis  of  our  product  portfolio  and  profitability  on  both  a  product  and  regional  basis.  With  this  increased
transparency at a product-level, we now have visibility to support customer pricing, marketing strategies and evaluate opportunities to increase
prices. Furthermore, focus will be on recurring revenue streams of our core business by leveraging more recently established distributor and direct
customer channels in the US and other key markets.

54

 
Table of Contents

•

•

•

Lower manufacturing costs: Automation and labor management is essential to scale unit volumes while also seeking additional ways to drive
our manufacturing costs down. With improved visibility on our labor and material costs at a product-level, we will primarily target optimization of
our lower margin business.

Reduce  infrastructure  costs:  This  includes  an  in-depth  evaluation  of  all  support  functions  and  external  spend  to  reduce  costs.  Research  &
Development will be further aligned with our future innovation centered on core strategy, including DPP and expansion of product pipeline with a
more disciplined approach to cost-benefit analysis, target markets, and competitor landscape.

Strategic  review  of  non-core  businesses  and  assets:  Our  prior  acquisitions  have  not  achieved  the  business  plans  as  originally  planned.  More
specifically, emphasis will be on both our German and Brazilian subsidiaries with a reorientation for those businesses to achieve an independent
path to profitability and alignment with the long-term strategic roadmap.

While  these  pillars  establish  a  framework  to  improve  our  profitability,  successful  execution  is  dependent  on  many  factors  including  future  regulatory
approvals, key relationships with long term customers and expansion in large markets including the US. We plan to aggressively implement these actions
that underpin fundamentals for long-term profitable growth and sustainable shareholder value.

Substantial Doubt as to Going Concern Status

Factors and considerations with respect to our liquidity raised substantial doubt as to our ability to continue as a going concern through one year after the
date that our financial statements are being issued.

Revenues  during  the  twelve  months  ended  December  31,  2021  did  not  meet  our  expectations.  Our  increase  in  cash  and  cash  equivalents  over  the  year
reflected  our  issuance  of  common  stock  in  at-the-market  offerings  for  net  proceeds  of  $38.8  million  (see  “Note  9  -  Stockholder’s  Equity”  to  the
Consolidated Financial Statements of this Annual Report on Form 10-K is incorporated herein by reference).

We  continued  to  experience  market,  clinical  trial  and  regulatory  complications  in  seeking  to  develop  and  commercialize  a  portfolio  of  COVID-19  test
systems during the continuing, but evolving, uncertainty of the COVID‑19 pandemic. In the year ending on December 31, 2021, we continued to incur
significant  expenses  in  connection  with  pending  legal  matters  (see  “Note  12  –  Commitments,  Contingencies,  and  Concentrations:  Litigation”  to  the
Consolidated Financial Statements of this Annual Report on Form 10-K is incorporated herein by reference), delayed achievement of milestones associated
with government grant income, investments in inventory, and the continuing automation of manufacturing.

During  the  twelve  months  ended  December  31,  2021,  we  undertook  measures  to  increase  our  total  revenues  and  improve  our  liquidity  position.  These
measures included:

•

On  July  19,  2021,  we  entered  into  an  At  the  Market  Offering  Agreement,  or  the  ATM  Agreement,  with  Craig‑Hallum  Capital  Group  LLC,  or
Craig‑Hallum, pursuant to which we may sell from time to time, at our option, up to an aggregate of $60,000,000 of shares of common stock through
Craig‑Hallum, as sales agent. As of the filing date of this report, we have issued and sold pursuant to the ATM Agreement a total of 9,709,328 shares
of common stock at a volume-weighted average price of $4.20 per share for gross proceeds of $40.8 million and net proceeds, after giving effect to
placement fees and other transaction costs, of $38.8 million.

• We also received significant purchase orders from two customers, which we refer to as the July Purchase Orders. We had pursued the July Purchase

Orders for an extended period of time. The July Purchase Orders consist of the following:

55

 
 
 
 
Table of Contents

o On  July  20,  2021,  we  received  a  $28.3  million  purchase  order  from  Bio-Manguinhos  for  the  purchase  of  DPP  SARS-CoV-2  Antigen  tests  for
delivery during 2021 to support the needs of Brazil’s Ministry of Health in addressing the COVID-19 pandemic. Bio-Manguinhos is responsible
for the development and production of vaccines, diagnostics, and biopharmaceuticals, primarily to meet demands of Brazil’s national public health
system. As of December 31, 2021 $16.8 million was recognized in connection with this order.

o On July 22, 2021, we received a $4.0 million purchase order from the Partnership for Supply Chain Management, supported by The Global Fund,
for the purchase of HIV 1/2 STAT-PAK Assays for shipment to Ethiopia into early 2022. As of December 31, 2021 $1.2 million was recognized in
connection with this order.

These measures and other plans and initiatives have been designed to provide us with adequate liquidity to meet our obligations for at least the twelve-
month period following the filing date of this report, when the Accompanying Financial Statements are being issued. Our execution of those measures and
our other plans and initiatives continue to depend, however, on factors that are beyond our control, or that may not be addressable on terms acceptable to us
or at all. We have considered in particular how:

•

•

The ongoing healthcare and economic impacts of the COVID-19 pandemic on the global customer base for our non‑COVID-19 products continue to
negatively affect the timing and rate of recovery of our revenues from those products by, for example, decreasing the allocation of funding for HIV
testing, thereby continuing to adversely affect our liquidity.

Although we have entered into agreements to distribute third-party COVID-19 products in the United States, our ability to sell those products could be
constrained because of staffing and supply chain limitations affecting the suppliers of those products.

We  further  considered  how  these  factors  and  uncertainties  could  impact  our  ability  over  the  next  year  to  meet  the  obligations  specified  in  the  Credit
Agreement and Guaranty, or the Credit Agreement, that we and certain of our subsidiaries, as guarantors, entered into with Perceptive Credit Holdings II,
LP, or the Lender. Those obligations include (a) covenants requiring: i) minimum cash balance of $3 million and ii) minimum total revenue amounts for the
twelve months preceding each quarter end. For the next year, the minimum total revenue requirements range from $42.0 million for the twelve months
ending  March  31,  2022  to  $47.4  million  for  the  twelve  months  ending  December  31,  2022  and  (b)  an  obligation  requiring  the  payment  of  principal
installments, commencing with the payment of $300,000 on September 30, 2022. Upon an event of default under the Credit Agreement, the Lender could
elect to declare all amounts outstanding thereunder, together with accrued interest, to be immediately due and payable. In such an event, there can be no
assurance that we would have sufficient liquidity to fund payment of the amounts that would be due under the Credit Agreement or that, if such liquidity
were not available, we would be successful in raising additional capital on acceptable terms, or at all, or in completing any other endeavor to continue to be
financially viable and continue as a going concern. Our inability to raise additional capital on acceptable terms in the near future, whether for purposes of
funding payments required under the Credit Agreement or providing additional liquidity needed for our operations, could have a material adverse effect on
our business, prospects, results of operations, liquidity and financial condition.

Accordingly, management determined we could not be certain that our plans and initiatives would be effectively implemented within one year after the
filing date of this report, when the Accompanying Financial Statements are being issued. Without giving effect to the prospect of raising additional capital
pursuant to our at-the-market offerings, increasing product revenue in the near future or executing other mitigating plans, many of which are beyond our
control, it is unlikely that we will be able to generate sufficient cash flows to meet our required financial obligations, including our debt service and other
obligations due to third parties. The existence of these conditions raises substantial doubt about our ability to continue as a going concern for the twelve-
month period following the filing date of this report.

The Accompanying Financial Statements have been prepared assuming we will continue as a going concern, which contemplates continuity of operations,
realization of assets and the satisfaction of liabilities in the normal course of business for the twelve-month period following the date the accompanying
consolidated financial statements are issued. As such, the Accompanying Financial Statements do not include any adjustments relating to the recoverability
and classification of assets and their carrying amounts, or the amount and classification of liabilities that may result should we be unable to continue as a
going concern.

Total  revenues  during  2021  were  $47.8  million,  an  increase  of  $15.3  million,  or  47.3%,  compared  to  2020.  The  increase  in  total  revenues  reflected  a
$10 million, or 40.3%, increase in net product sales, which was principally comprised of (a) higher sales in Latin America, US and Africa, offset by lower
sales in Europe and Asia; (b) decrease in R&D revenue of $3.7 million due to the completion of agreements in the early part of 2021; and (c) increase in
grant income related to the BARDA $12.7 million agreement in the amount of $8.9 million.

Gross Product Margin

Cost of product sales is primarily comprised of material, labor, manufacturing overhead, depreciation and amortization, and freight and distribution costs.
Gross product margin is net product sales less cost of product sales, and gross product margin percentage is gross product margin as a percentage of net
product sales.

Gross product margin decreased by $0.7 million, or 73% compared to 2020. The following schedule calculates gross product margin:

In 2021, we invested in developing and offering products to address the COVID-19 pandemic, which we expected to have average selling prices greater
than  those  of  our  legacy  products.  We  also  continued  to  invest  in  automation  in  order  to  reduce  our  reliance  on  manual  labor  and  improve  our  product
margins. The $0.7 million decrease in gross product margin was comprised of (a) $1.0 million from unfavorable product margins offset by (b) $0.3 million
favorable product sales volume as described under “—Total Revenues” above. The $1.0 million decrease from unfavorable product margins principally
reflected the increased labor and overhead costs and unfavorable mix of average selling prices.

The increase in clinical and regulatory affairs costs for 2021 as compared to 2020 was primarily associated with increased clinical trial costs related to the
BARDA $12.7 million agreement which was completed on December 2, 2021. The decrease in other research and development costs was primarily related
to the completion of R&D agreements in the early part of 2021.

Selling, General and Administrative Expense

Selling,  general  and  administrative  expenses  include  administrative  expenses,  sales  and  marketing  costs  (including  commissions),  and  other  corporate
items. The $3.8 million, or 18.1%, increase in selling, general and administrative expenses for 2021 as compared to 2020 primarily reflected increased legal
costs associated with the ongoing litigations, recruiting fees due to the ramp up in production that took place in the later part of 2021 and higher insurance
costs.

Impairment, restructuring. severance and related costs

The Company recorded an impairment loss of $1.3 million during the second quarter of 2021, as the result of its write-off of the intangible assets, net,
leasehold  improvements,  net  and  right-of-use  assets  for  leases,  net  associated  with  its  Malaysian  operations  that  underwent  a  retrenchment  during  the
second quarter of 2020.

In  addition,  the  Company  recorded  an  impairment  loss  of  $4.6  million  during  the  fourth  quarter  of  2021,  as  the  result  of  a  write  down  of  finite-lived
intangible assets ($2.0 million) and goodwill ($2.6 million) due to the substantial decrease in share price as of December 31, 2021. The  low price per share
value on December 31, 2021 caused the book value of the Company to exceed its market cap.

In light of the uncertainty of the timing and any receipt of those regulatory approvals, the timing of progress on and results of clinical trial programs, and
the timing and any receipt of product orders from the commercialization of the COVID-19 Diagnostic Test Systems and other diagnostic test systems both
within and outside the United States, during the second quarter of 2021, the Company engaged the services of an independent financial advisory firm (the
“Financial Advisor”).  The  Financial  Advisor  worked  with  management  to  develop  a  forecast  model  to  assess  the  amount  and  timing  of  the  Company’s
liquidity needs, assuming various business cases, and together with legal counsel advised the Company regarding alternative approaches to enhancing its
liquidity  position,  participating  in  discussions  with  the  Lender,  and  related  matters.  During  the  year  ended  December  31,  2021  and  2020,  the  Company
incurred $1.1 and $0.4 million, respectively, related to these restructuring matters.

In order to address challenging economic conditions and implement its business strategy, in the first quarter of 2021 the Company continued to execute a
program  to  reduce  operating  expenses  and  better  align  its  costs  with  revenues,  including  by  eliminating  positions  that  were  no  longer  aligned  with  its
strategy, and recognized severance charges of $0.1 million.

Table of Contents

Acquisition Costs

Acquisition costs include legal, due diligence, audit, and related costs associated with acquisitions. The $0.1 million decrease in acquisition costs for 2021
as compared to 2020 reflected the fact that we completed acquisitions in 2020.

Other (Expense) / Income

Other  (expense)  /  income    was  principally  comprised  of  interest  expense  net  of  interest  income.  Interest  expense  increased  by  $0.1  million  for  2021  as
compared to 2020, due to the interest paid on the term loan debt we incurred in September 2019.

Income Tax Benefit

For 2021 we recognized a tax benefit of $0.1 primarily attributable to the loss generated by Chembio Diagnostics Germany. As of December 31, 2021 and
2020, the Company recorded a full valuation allowance against its net deferred tax assets.

Liquidity and Capital Resources

Our cash and cash equivalents totaled $28.8 million at December 31, 2021, an increase of $5.7 million from $23.1 million at December 31, 2020. We
are obligated to maintain aggregate unrestricted cash of not less than $3,000,000 at all times under a covenant in the Credit Agreement.

During the year ended December 31, 2021, we funded our business operations, including capital expenditures and working capital requirements, principally
from  cash  and  cash  equivalents  and  issuance  of  common  stock  in  at-the-market  offerings.  Our  operations  used  $30.9  million  of  cash  during  the  twelve
months ended December 31, 2021. In the first half of 2021, revenues did not meet our expectations, and the shortfall in revenues from the first two quarters
was one of the principal reasons we issued common stock in the at-the-market offerings during the year ended December 31, 2021, which provided us with
net  proceeds  of  $38.8  million.  This  increase  in  cash  and  cash  equivalents  was  offset  in  part  as  the  result  of  (a)  market,  clinical  trial  and  regulatory
complications we faced in seeking to develop and commercialize a portfolio of COVID‑19 test systems during the continuing, but evolving, uncertainty of
the  COVID‑19  pandemic  and  (b)  significant  continuing  expenses  incurred  in  connection  with  pending  legal  matters  (see  “Note  12(e)  –  Commitments,
Contingencies,  and  Concentrations  –  Litigation”  in  the  Accompanying  Financial  Statements),  delayed  achievement  of  milestones  associated  with
government grant income, investments in inventory, and, the continuing automation of U.S. manufacturing.

In light of the uncertainty of the timing and any receipt of regulatory approvals, the timing of progress on and results of clinical trial programs, and the
timing and any receipt of product orders from the commercialization of our COVID‑19 and other diagnostic test systems both within and outside the United
States, during the year we engaged the services of an independent financial advisory firm. The financial advisory firm worked with management to develop
a  forecast  model  to  assess  the  amount  and  timing  of  our  liquidity  needs,  assuming  various  business  cases  and,  together  with  legal  counsel,  advised  us
regarding  alternative  approaches  to  enhancing  our  liquidity  position,  participating  in  discussions  with  the  Lender  under  our  credit  facility  and  related
matters. We incurred fees related to these restructuring matters totaling $1.1 million in during the year.

Factors and considerations with respect to our liquidity raised substantial doubt as to our ability to continue as a going concern through one year after the
date that the Accompanying Financial Statements are being issued. See “—Substantial Doubt as to Going Concern Status” above.

Table of Contents

We have undertaken plans and initiatives, including fulfillment of the July Purchase Orders (see “— Substantial Doubt as to Going Concern Status” above)
and fundraising through “at-the-market” offerings (see “—Substantial Doubt as to Going Concern Status” above), designed to provide us with adequate
liquidity to meet our obligations for at least the twelve-month period following the filing date of this report, when the Accompanying Financial Statements
are  being  issued.  Our  execution  of  those  plans  and  initiatives  is  dependent,  however,  on  a  number  of  operational  performance  factors,  such  as  the
effectiveness of our automated manufacturing operations, as well as numerous other factors that are beyond our control or that may not be addressable on
terms acceptable to us, or at all. We have considered how the uncertainties around the delivery of the full number of tests covered by customer orders may
be  affected  by  limitations  of  our  staffing,  supply  chain  and  liquidity,  uncertainties  regarding  the  achievement  of  milestones  and  related  recognition  of
revenue under government grants from BARDA, and other matters outside our control. We further considered how those uncertainties could impact our
ability  to  meet  the  obligations  specified  in  the  Credit  Agreement  over  the  next  twelve  months,  which  include  (a)  a  covenant  requiring  minimum  total
revenues for the twelve months preceding each quarter end, which requirements range from $40.3 million for the twelve months ending December 31, 2021
to $47.4 million for the twelve months ending December 31, 2022 and (b) an obligation requiring the payment of principal installments, commencing with
the  payment  of  $300,000  on  September  30,  2022.  Upon  an  event  of  default  under  the  Credit  Agreement,  the  Lender  could  elect  to  declare  all  amounts
outstanding thereunder, together with accrued interest, to be immediately due and payable. In such an event, there can be no assurance that we would have
sufficient liquidity to fund payment of the amounts that would be due under the Credit Agreement or that, if such liquidity were not available, we would be
successful in raising additional capital on acceptable terms, or at all, or in completing any other endeavor to continue to be financially viable and continue
as a going concern. Our inability to raise additional capital on acceptable terms or to otherwise generate cash in the near future, whether for purposes of
funding payments required under the Credit Agreement or providing additional liquidity needed for our operations, could have a material adverse effect on
our business, prospects, results of operations, liquidity and financial condition.

We  cannot  be  certain  that  our  plans  and  initiatives  would  be  effectively  implemented  within  one  year  after  the  filing  date  of  this  report,  when  the
Accompanying  Financial  Statements  are  being  issued.  Without  giving  effect  to  the  prospect  of  raising  additional  capital  pursuant  to  our  at-the-market
offerings, increasing product revenue in the near future or executing other mitigating plans, many of which are beyond our control, it is unlikely that we
will be able to generate sufficient cash flows to meet our required financial obligations, including our debt service and other obligations due to third parties.
The existence of these conditions raises substantial doubt about our ability to continue as a going concern for the twelve-month period following the date of
this report.

Please  see  note  2  to  the  Accompanying  Financial  Statements  for  additional  information  regarding  our  going  concern  assessment  in  connection  with  the
Accompanying Financial Statements. You are urged to read carefully the information provided in “Because of our liquidity limitations, we have concluded
there is a substantial doubt about our ability to continue as a going concern and we may require additional capital to fund our operations, which capital may
not be available to us on acceptable terms or at all,” “Because of our liquidity and operational limitations, including the availability of staffing and supply
chain resources that are necessary but outside of our control, we may not be able to timely fulfill some of the requirements of the July Purchase Orders
without additional capital to fund our operations, which capital may not be available to us on acceptable terms, or at all,” and “The failure to comply with
the terms of the Credit Agreement could result in a default under its terms and, if uncured, could result in action against our pledged assets and dilution of
our stockholders” under “Item 1A. Risk Factors” of Part I of this report.

We currently intend to retain all available funds and any future earnings for use in the operation of our business and do not anticipate paying any cash
dividends. We have not entered into, and do not expect to enter into, investments for trading or speculative purposes. Our accounts receivable, accounts
payable and inventory balances fluctuate from period to period, which affects our cash flow from operating activities. The amounts of these fluctuations
vary depending on cash collections, client mix, raw material lead times, the mix of vendor terms, the timing of shipment of our products and the invoicing
of our research and development activities. As of December 31, 2021, we did not have any off-balance sheet arrangements, as defined in Item 303(a)(4)(ii)
of Regulation S-K under the Securities Exchange Act of 1934.

Table of Contents

We continually evaluate our liquidity requirements, capital needs and availability of capital resources based on our operating needs and our planned growth
initiatives. Our future working capital needs will depend on many factors, including the rate of our business and revenue growth, the availability and cost of
human,  material  and  other  resources  required  to  build  and  deliver  products  in  accordance  with  our  existing  or  future  product  orders,  the  timing  of  our
continuing automation  of  U.S.  manufacturing,  and  the  timing  of  our  investment  in  research  and  development  as  well  as  sales  and  marketing.  If  we  are
unable to increase our revenues and manage our expenses in accordance with our operating plan, we may need to reduce the level or slow the timing of the
growth plans contemplated by our operating plan, which would likely curtail or delay the growth in our business contemplated by our operating plan and
could  impair  or  defer  our  ability  to  achieve  profitability  and  generate  cash  flow,  or  to  seek  to  raise  additional  funds  through  debt  or  equity  financings,
strategic relationships, or other arrangements. There can be no assurance that we would be able to complete any proposed financing on terms acceptable to
us, or at all, or that we otherwise will be successful in any of our other endeavors to continue to be financially viable and continue as a going concern. Our
inability to raise additional capital on acceptable terms could have a material adverse effect on our business, prospects, results of operations, liquidity and
financial condition. If we were to raise additional funds through the issuance of equity or convertible securities, the issuance could result in substantial
dilution  to  existing  stockholders,  and  the  holders  of  those  new  securities  may  have  rights,  preferences  and  privileges  senior  to  those  of  the  holders  of
common  stock.  Furthermore,  any  decline  in  the  market  price  of  our  common  stock  could  make  it  more  difficult  for  us  to  sell  equity  or  equity-related
securities in the future at a time and price that we deem appropriate.

Sources of Funds

Equity and Equity-Related Securities. On July 19, 2021, we entered into the ATM Agreement with Craig‑Hallum, pursuant to which we may sell from
time to time, at our option, up to an aggregate of $60,000,000 of shares of common stock through Craig‑Hallum, as sales agent. Any sales of shares made
pursuant to the ATM Agreement will be made pursuant to our shelf registration statement on Form S‑3 (File No. 333‑254261) and the related prospectus
previously declared effective by the SEC on May 5, 2021, as supplemented by a prospectus supplement dated July 19, 2021 that we filed with the SEC,
pursuant to Rule 424(b)(5) under the Securities Act, on July 19, 2021, as such prospectus supplement may be amended or supplemented from time to time.

Prior to any sale of shares of common stock under the ATM Agreement, we may deliver a sales notice to Craig-Hallum that will set the parameters for such
sale, including the number of shares to be issued and sold, the time period during which such sale is requested to be made, any limitation on the number of
shares that may be sold in any one trading day and any minimum price below which sales may not be made. Under the ATM Agreement, Craig-Hallum is
required to use commercially reasonable efforts consistent with its normal trading and sales practices to sell shares in accordance with the terms of the
ATM Agreement and any applicable sales notice.

Subject to the terms and conditions of the ATM Agreement, Craig-Hallum may sell any shares of common stock only by methods deemed to be an “at the
market” offering as defined in Rule 415 under the Securities Act, including sales made directly through the Nasdaq Capital Market, by means of ordinary
brokers’ transactions, in negotiated transactions, to or through a market maker other than on an exchange or otherwise, at market prices prevailing at the
time  of  sale,  at  prices  related  to  such  prevailing  market  prices,  or  at  negotiated  prices  and/or  any  other  method  permitted  by  law.  If  any  sale  of  shares
pursuant to the ATM Agreement is not made directly on the Nasdaq Capital Market or any other existing trading market for common stock at market prices
at the time of sale, including a sale to Craig-Hallum acting as principal or a sale in a privately negotiated transaction, we must file a prospectus supplement
describing the terms of such sale, the number of shares sold, the price of the shares, the applicable compensation, and such other information as may be
required pursuant to Rules 424 and 430B under the Securities Act, as applicable, within the time required by Rule 424 under the Securities Act.

Under the terms of the ATM Agreement, we are to pay Craig-Hallum a placement fee of 3.5% of the gross sales price of shares of common stock sold,
unless Craig-Hallum acts as principal, in which case we may sell the shares to Craig-Hallum as principal at a price we agree upon with Craig-Hallum. We
are obligated to reimburse Craig-Hallum for certain expenses incurred in connection with the ATM Agreement, and we have provided Craig-Hallum with
customary  indemnification  and  contribution  rights  with  respect  to  certain  liabilities,  including  liabilities  under  the  Securities  Act  and  the  Securities
Exchange Act of 1934.

The offering of shares of common stock pursuant to the ATM Agreement will terminate upon the earliest of (a) the sale of all of the shares registered for
purposes of the offering pursuant to the ATM Agreement, (b) our mutual written agreement with Craig-Hallum, (c) written notice from Craig-Hallum, in its
sole discretion, to us, and (d) five business days’ prior written notice from us, in our sole discretion, to Craig-Hallum.

As of the filing date of this report, we have issued and sold pursuant to the ATM Agreement a total of 9,709,328 shares of common stock at a volume-
weighted average price of $4.20 per share for gross proceeds of $40.8 million and net proceeds, after giving effect to placement fees and other transaction
costs, of $38.8 million. Additional shares of common stock may be issued and sold pursuant to the ATM Agreement for gross proceeds of up to $19.2
million, but we cannot provide any assurance that will be able to issue any additional shares under the ATM Agreement at an acceptable price or at all.

Credit Agreement. The following description summarizes certain key provisions of the Credit Agreement:

•

•

•

•

•

•

•

Principal  Amount.  The  Credit  Agreement  provides  for  a  $20,000,000  senior  secured  term  loan  credit  facility,  which  was  drawn  in  full  on
September  4,  2019.  Under  the  terms  of  the  Credit  Agreement,  we  may  use  the  proceeds  (a)  for  general  working  capital  purposes  and  other
permitted corporate purposes, (b) to refinance certain of our existing indebtedness and (c) to pay fees, costs and expenses incurred in connection
with the Credit Agreement, including the Lender’s closing cost amount of $550,000, which was netted from the proceeds, and a financing fee of
$600,000 (3.0% of gross proceeds) payable to Craig-Hallum, our financial advisor for the financing.

Interest Rate. Principal outstanding under the Credit Agreement bears interest at a rate per annum equal to the sum of (a) the greater of the one
month  London  Interbank  Offered  Rate  and  2.5%  plus  (b)  8.75%.  At  any  time  at  which  an  event  of  default  (as  described  under  “—Default
Provisions” below) has occurred and is continuing, the interest rate will increase by 4.0%. Accrued interest is payable  on  a  monthly  basis.  On
December 31, 2021 the interest rate was 11.25%.

Scheduled Repayment. No principal repayments are due prior to September 30, 2022, unless we elect to prepay principal as described under “—
Optional Prepayment” below or principal is accelerated pursuant to an event of default as described under “—Default Provisions” below. Principal
installments in the amount of $300,000 are payable on the last day of each of the eleven months from September 2022 through July 2023, and all
remaining principal is payable at maturity on September 3, 2023.

Optional Prepayment. We may prepay outstanding principal from time to time, subject to payment of a premium on the prepaid principal amount
equal to 4% through September 3, 2022. No premium will be due with respect to any prepayment made on or after September 4, 2022.

Guarantees. Our subsidiaries Chembio Diagnostic Systems Inc. and Chembio Diagnostics Malaysia Sdn Bhd. have guaranteed, and the Lender
from time to time may require our other subsidiaries to guarantee, our obligations under the Credit Agreement.

Security. Our obligations under the Credit Agreement are secured by a first priority, perfected lien on substantially all of our property and assets,
including  our  equity  interests  in  our  subsidiaries.  Our  subsidiary  Chembio  Diagnostic  Systems  Inc.  has  secured  its  guarantee  of  our  Credit
Agreement obligations with a lien on substantially all of its assets, and the Lender from time to time may require Chembio Diagnostics Malaysia
Sdn Bhd. and any of our other subsidiaries that has guaranteed our Credit Agreement obligations to do the same.

Representations and Warranties. Financial and Other Covenants. In the Credit Agreement we made customary representations and warranties as
well  as  customary  affirmative  and  negative  covenants,  including  covenants  limiting  additional  indebtedness,  liens,  guarantees,  mergers  and
acquisitions, substantial asset sales, investments and loans, sale and leasebacks, transactions with affiliates, and fundamental changes. The Credit
Agreement also contains financial covenants requiring that (a) we maintain aggregate unrestricted cash of not less than $3,000,000 at all times and
(b)  we  achieve  specified  minimum  total  revenue  requirements  for  the  twelve  months  preceding  each  quarter  end.  The  minimum  total  revenue
amounts range from $32.0 million to $50.1 million and, for the next year, range from $42.0 million for the twelve months ending March 31, 2022
to $47.4 million for the twelve months ending December 31, 2022. The minimum total revenue requirements were developed for purposes of the
Credit Agreement and do not reflect the internal estimates and plans used by our management and board of directors to understand and evaluate
our operating performance, to establish budgets, and to establish operational goals for managing our business. We therefore do not believe that the
covenant requirements provide useful information to investors or others in enhancing an understanding of our future prospects.

Default Provisions. The Credit Agreement provides for customary events of default, including events of default based on non-payment of amounts
due under the Credit Agreement, defaults on other debt, misrepresentations, covenant breaches, changes of control, insolvency, bankruptcy and the
occurrence  of  a  material  adverse  effect  on  our  company.  Upon  an  event  of  default  resulting  from  a  voluntary  or  involuntary  proceeding  for
bankruptcy, insolvency or receivership, the amounts outstanding under the Credit Agreement will become immediately due and payable and the
Lender’s  commitments  will  be  automatically  terminated.  Upon  the  occurrence  and  continuation  of  any  other  event  of  default,  the  Lender  may
accelerate payment of all obligations and terminate its commitments under the Credit Agreement.

Research and Development Awards. Under a contract we entered into with BARDA on December 2, 2020, a total of up to $12.7 million of awards were
available from BARDA to assist us in (a) developing, and pursuing an EUA from the FDA for, the DPP Respiratory Antigen Panel and (b) performing the
clinical  trials  for  and  submitting  the  DPP  SARS-CoV-2  Antigen  test  system  to  the  FDA  for  510(k)  clearance.  Of  the  total  awards  available  under  this
contract, we recognized government grant income totaling $10.9 million during the year ended December 31, 2021. The completion of milestones to earn
the remaining awards are outside our control, and contingent to the EUA approval by the FDA.

Our cash and cash equivalents at December 31, 2021, were held for working capital purposes. We currently intend to retain all available funds and any
future earnings for use in the operation of our business and do not anticipate paying any cash dividends. We have not entered into, and do not expect to
enter into, investments for trading or speculative purposes. Our accounts receivable and inventory balances fluctuate from period to period, which affects
our cash flow from operating activities. Fluctuations vary depending on cash collections, client mix, raw material lead times, the mix of vendor terms, and
the timing of shipment of our products and the invoicing of our research and development activities.

Uses of Funds

Cash Flow Used in Operating Activities. Our operations used $30.9 million of cash during the year ended December 31, 2021, primarily due to the net
loss adjusted for non-cash items of $18.8 million. Those uses of cash were the result of $8.0 million increase in accounts receivable, a $4.5 million increase
in  inventory,  $1.6  million  decrease  in  deferred  revenue  and  $0.9  million  decrease  in  Prepaid  and  other  current  assets,  offset  in  part  by  a  $3.1  million
increase in accounts payable and other accrued liabilities.

Credit Agreement. Principal installments in the amount of $300,000 are payable under the Credit Agreement on the last day of each of the eleven months
from  September  2022  through  July  2023,  and  all  remaining  principal  is  payable  at  maturity  on  September  3,  2023.  Upon  an  event  of  default  under  the
Credit Agreement, the Lender could elect to declare all amounts outstanding thereunder, together with accrued interest, to be immediately due and payable,
as further described “—Sources of Funds—Credit Agreement—Default Provisions” above. In addition, we could determine to prepay from time to time
outstanding  principal  under  the  Credit  Agreement  (see  “—Sources  of  Funds—Credit  Agreement—Optional  Prepayment”  above)  or  to  make  other
payments under the Credit Agreement that may not be then due or otherwise required under the Credit Agreement, although, as of the date of the filing of
this report, we do not intend to make any such prepayments or other payments.

Capital  Expenditures.  Our  capital  expenditures  totaled  $1.9  million  in  the  year  ended  December  31,  2021,  all  of  which  related  to  investments  in
automated  manufacturing  equipment,  facilities,  and  other  fixed  assets.  As  of  December  31,  2021,  we  had  capital  purchase  obligations  of  $1.5  million
related to additional automated manufacturing equipment, with payments expected to come due during 2022 based on vendor performance milestones.

Significant Accounting Policies and Critical Accounting Estimates

Our  significant  accounting  policies  are  described  in  Note  2  –  Significant  Accounting  Policies  to  the  audited  consolidated  financial  statements  included
herein.  Certain  of  our  accounting  policies  require  the  application  of  significant  judgment  by  management  in  selecting  the  appropriate  assumptions  for
calculating  financial  estimates.  By  their  nature,  these  judgments  are  subject  to  an  inherent  degree  of  uncertainty.  These  judgments  are  based  on  our
historical experience, terms of existing contracts, our evaluation of trends in the industry, information provided by our customers and information available
from other outside sources, as appropriate. We consider an accounting estimate to be critical if (a) it requires us to make assumptions about matters that
were uncertain at the time we were making the estimate and (b) changes in the estimate or different estimates that we could have selected would have had a
material impact on our financial condition or results of operations.

The following listing is not intended to be a comprehensive list of all of our accounting policies.  In many cases, the accounting treatment of a particular
transaction  is  specifically  dictated  by  accounting  principles  generally  accepted  in  the  United  States,  with  no  need  for  management’s  judgment  in  their
application. There are also areas in which management’s judgment in selecting any viable alternative would not produce a materially different result.

Revenue Recognition

We  recognize  revenue  for  product  sales  in  accordance  with  Financial  Accounting  Standards  Board  Accounting  Standards  Codification,  or  ASC,  606,
Revenue from Contracts with Customers. Revenues from product sales are recognized when the customer obtains control of our product, which occurs at a
point in time, typically upon tendering to the customer. We expense incremental costs of obtaining a contract as and when incurred because the expected
amortization period of the asset that it would have recognized is one year or less or the amount is immaterial. Freight and distribution activities on products
are performed after the customer obtains control of the goods. We have made an accounting policy election to account for shipping and handling activities
that occur either when or after goods are tendered to the customer as a fulfillment activity, and therefore recognizes freight and distribution expenses in cost
of product sales. We exclude certain taxes from the transaction price (e.g., sales, value added and some excise taxes).

Estimates of variable consideration and the determination of whether to include estimated amounts in the transaction price are based on all information
(historical, current, and forecasted) that is reasonably available to us, taking into consideration the type of customer, the type of transaction, market events
and trends, and the specific facts and circumstances of each arrangement.

For  applicable  contracts,  we  recognize  revenue  from  research  and  development,  milestone  and  grant  revenues  when  earned.    Grants  are  invoiced  after
expenses  are  incurred.  Revenues  from  projects  or  grants  funded  in  advance  are  deferred  until  earned.  For  certain  collaborative  research  projects,  we
recognize  revenue  by  defining  milestones  at  the  inception  of  the  agreement  and  applying  judgment  and  estimates  in  recognizing  revenue  for  relevant
contracts.

Table of Contents

From time to time the Company engages in bill-and-hold arrangements, whereby the Company manufactures and sells its product and at the customer’s
request stores the product at the Company’s warehouse. Even though the product remains in the Company’s possession, a sale is recognized at the point in
time  when  the  customer  obtains  control  of  the  product.  Control  is  transferred  to  the  customer  in  bill  and  hold  transactions  when:  customer  acceptance
specifications have been met, legal title has transferred, the customer has a present obligation to pay for the product and the risk and rewards of ownership
have transferred to the customer.  Additionally, all the following bill and hold criteria would have to be met in order for control to be transferred to the
customer:

(a) The reason for the bill-and-hold arrangement must be substantive (for example, the customer has requested the arrangement).
(b) The product must be identified separately as belonging to the customer.
(c) The product currently must be ready for physical transfer to the customer.
(d) The entity cannot have the ability to use the product or to direct it to another customer.

Goodwill

We periodically review goodwill for impairment indicators. We review goodwill for impairment annually in the fourth quarter or more frequently if events
or changes in circumstances indicate that goodwill might be impaired. We perform the goodwill impairment review at the reporting unit level. We perform
a qualitative assessment of whether it is more likely than not that a reporting unit’s fair value is less than its carrying amount. If not, no further goodwill
impairment testing is performed. If so, we perform the step discussed hereafter. Our qualitative assessment involves significant estimates, assumptions, and
judgments, including, macroeconomic conditions, industry and market conditions, our financial performance, reporting unit specific events and changes in
our share price.

If the fair value of the reporting unit is greater than its carrying amount, goodwill is not considered to be impaired. We would recognize an impairment
charge  for  the  amount  by  which  the  carrying  amount  exceeds  the  reporting  unit’s  fair  value,  provided  the  impairment  charge  does  not  exceed  the  total
amount of goodwill allocated to the reporting unit.

The company operates as a single operating segment and has one reporting unit. During the year ended December 31, 2021, the Company performed a
quantitative analysis and determined that the carrying value exceeded its fair value by $2.6 million, on December 31, 2021.

Recently Issued Accounting Pronouncements

Refer  to  Note  2  –  Significant  Accounting  Policies  to  the  audited  consolidated  financial  statements  included  herein  for  a  complete  description  of  recent
accounting standards that we have not yet been required to implement which may be applicable to our operations. Additionally, the significant accounting
standards that have been adopted during the year ended December 31, 2021 are described.

ITEM 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls
and procedures, as defined by Rules 13a-15(e) and 15d-15(e) under the Exchange Act, as of December 31, 2021. Based on the evaluation of our disclosure
controls and procedures, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of
December 31, 2021 at the reasonable assurance level.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting
is defined in Rules 13a-15(f) and 15d-15(f) promulgated under the Securities Exchange Act of 1934 as a process designed by, or under the supervision of,
our Chief Executive Officer and Chief Financial Officer and effected by the board of directors, management and other personnel to provide reasonable
assurance  regarding  the  reliability  of  financial  reporting  and  the  preparation  of  financial  statements  for  external  purposes  in  accordance  with  generally
accepted accounting principles and includes those policies and procedures that:

•

•

•

pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the
company;
provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally
accepted accounting principles, and that receipts and expenditures of the company are being made in accordance with authorizations of
management and directors of the company; and
provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company’s assets that
could have a material effect on the financial statements.

Because  of  its  inherent  limitations,  internal  control  over  financial  reporting  may  not  prevent  or  detect  misstatements.  As  a  result,  even  those  systems
determined  to  be  effective  can  provide  only  reasonable  assurance  with  respect  to  financial  statement  preparation  and  presentation.  Projections  of  any
evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions or that the degree
of compliance with the policies or procedures may deteriorate.

Under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, our management evaluated the effectiveness of
our  internal  control  over  financial  reporting  as  of  December  31,  2021.  In  making  their  assessment  of  internal  control  over  financial  reporting,  our
management used the criteria described in the 2013 Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the
Treadway Commission. Our evaluation included documenting, evaluating and testing of the design and operating effectiveness of our internal control over
financial reporting. Based on this evaluation, we concluded that our controls over financial reporting were effective as of December 31, 2021.

Previously Identified Material Weaknesses in Internal Control Over Financial Reporting

None.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting identified in management’s evaluation pursuant to Rules 13a-15(d) or 15d-15(d) of
the Securities Exchange Act of 1934 during the period covered by this Annual Report on Form 10-K that materially affected, or are reasonably likely to
materially affect, our internal control over financial reporting.

Inherent Limitations of Internal Control

Management,  including  the  Company’s  Chief  Executive  Officer  and  Chief  Financial  Officer,  does  not  expect  that  the  Company’s  internal  controls  will
prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance
that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints and the
benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of internal control
can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. Also, any evaluation of the effectiveness of internal
controls in future periods are subject to the risk that those internal controls may become inadequate because of changes in business conditions, or that the
degree of compliance with the policies and procedures may deteriorate.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of Chembio Diagnostics, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheet of Chembio Diagnostics, Inc. (and subsidiaries) (the Company) as of December 31, 2021
and 2020, the related consolidated statements of operations, comprehensive loss,  stockholders'  equity  and  cash  flows  for  the  years  ended  December  31,
2021  and  2020,  and  the  related  notes  (collectively  referred  to  as  the  “consolidated  financial  statements”).  In  our  opinion,  the  consolidated  financial
statements present fairly, in all material respects, the financial position of the Company at December 31, 2021 and 2020, and the results of its operations
and its cash flows for each of the two years in the period ended December 31, 2021, in conformity with U.S. generally accepted accounting principles.

The Company’s Ability to Continue as a Going Concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in
Note 2  to  the  consolidated  financial  statements,  the  Company  has  suffered  recurring  losses  from  operations  and  has  stated  that  substantial  doubt  exists
about the Company’s ability to continue as a going concern. Management's evaluation of the events and conditions and management’s plans regarding these
matters  are  also  described  in  Note  2.  The  consolidated  financial  statements  do  not  include  any  adjustments  that  might  result  from  the  outcome  of  this
uncertainty. As explained below, auditing the Company’s evaluation of its ability to continue as a going concern was a critical audit matter.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial
statements  based  on  our  audits.  We  are  a  public  accounting  firm  registered  with  the  Public  Company  Accounting  Oversight  Board  (United  States)
(PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and
regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor
were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of
internal  control  over  financial  reporting  but  not  for  the  purpose  of  expressing  an  opinion  on  the  effectiveness  of  the  Company's  internal  control  over
financial reporting. Accordingly, we express no such opinion.

Our  audits  included  performing  procedures  to  assess  the  risks  of  material  misstatement  of  the  financial  statements,  whether  due  to  error  or  fraud,  and
performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in
the  financial  statements.  Our  audits  also  included  evaluating  the  accounting  principles  used  and  significant  estimates  made  by  management,  as  well  as
evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The  critical  audit  matters  communicated  below  are  matters  arising  from  the  current  period  audit  of  the  financial  statements  that  were  communicated  or
required  to  be  communicated  to  the  audit  committee  and  that:  (1)  relate  to  accounts  or  disclosures  that  are  material  to  the  financial  statements  and  (2)
involved  our  especially  challenging,  subjective,  or  complex  judgments.  The  communication  of  the  critical  audit  matters  does  not  alter  in  any  way  our
opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing a separate
opinion on the critical audit matters or on the accounts or disclosures to which they relate.

Description of the
Matter

Revenue Recognition – Transfer of Control
For the year ended December 31, 2021, the Company recognized $34.7 million of net product revenue. As discussed in Note 2 to
the consolidated financial statements, product revenue is recognized when the customer obtains control of the Company’s product
in an amount that reflects the consideration which the Company expects to receive in exchange for those goods or services.

Auditing the determination of transfer of control to recognize revenue was especially complex due to the variability in the terms
and conditions within certain customer contracts. Customer contracts must be carefully evaluated for terms that may affect the
timing or measurement of revenue recognition, including any bill-and-hold arrangements.

How We Addressed the
Matter in Our Audit

To  test  the  transfer  of  control,  our  audit  procedures  included,  among  others,  testing  that  the  Company  recorded  revenue  in
accordance with the terms and conditions of the contract by testing a sample of customer contracts. As part of this testing, we
inspected the executed customer contract to identify the performance obligation and when the transfer of control occurred. We
evaluated  the  Company’s  assessment  as  to  when  the  performance  obligation  was  fulfilled,  and  that  revenue  was  properly
recognized within the correct period. Our procedures also included inspecting third-party evidence of transfer of control to the
customer, and where appropriate, we also confirmed with customers contract terms and conditions. We also performed cut-off
testing around period end in order to test that revenue was properly recognized in the correct period.

Going Concern

Description of the
Matter

As discussed in Note 2, the determination as to whether the Company can continue as a going concern includes consideration of
management’s operating plan and anticipated timing of future cash flows.  The Company’s Credit Agreement contains covenants
that,  among  other  items,  require  the  Company  to  maintain  a  minimum  cash  balance  and  meet  certain  minimum  revenue
requirements.  This matter is also described in the "Going Concern Uncertainty" section of our report.  Management is required to
make subjective judgments and assumptions in concluding on going concern uncertainty.

Auditing the Company’s going concern assessment is complex because it involves a high degree of auditor judgment to assess the
reasonableness of the cash flow forecasts used in the Company’s going concern analysis. In particular, the cash flows are sensitive

 
 
 
 
 
 
 
 
 
to  changes  related  to  significant  assumptions,  such  as  the  estimation  of  the  future  cash  to  be  used  in  operations,  projected  net
revenue,  projected  earnings  before  interest,  taxes,  depreciation  and  amortization,  and  compliance  with  debt  covenants.  The
Company’s  ability  to  achieve  forecasted  results  is  judgmental  given  the  unpredictability  of  its  customers  spending  habits  as  a
result of the COVID-19 pandemic.

How We Addressed the
Matter in Our Audit

To  test  the  future  cash  flow  forecasts,  we  performed  audit  procedures  that  included,  among  others,  evaluating  and  testing  the
significant  assumptions  discussed  above  and  the  underlying  data  used  by  the  Company  in  its  analysis.  This  testing  included
inquiries with management, comparison of prior period forecasts to actual results, consideration of contrary evidence impacting
management’s forecasts, and the Company’s financing arrangements in place as of the report date.

Goodwill and Long-Lived Assets Impairment

Description of the
Matter

As discussed in Notes 2 and 14 to the consolidated financial statements, the Company identified indicators of impairment, which
resulted in the Company assessing the value of goodwill and its long-lived asset group for recoverability. The Company's analysis
resulted in goodwill and long-lived asset impairment charges of $2.6 million and $2.0 million, respectively.

Auditing  the  Company's  measurement  of  impairment  involved  a  high  degree  of  subjectivity  as  estimates  underlying  the
determination of fair values were based on assumptions about future economic conditions. Significant assumptions used in the
Company's  fair  value  estimates  included  projected  net  revenue  and  projected  earnings  before  interest,  taxes,  depreciation  and
amortization.

How We Addressed the
Matter in Our Audit

To test the future economic conditions, as part of our audit, we assessed the methodologies and significant assumptions used in
the impairment tests, among other procedures. We tested the significant assumptions discussed above, as well as the completeness
and  accuracy  of  the  underlying  data  used  in  the  valuations.  In  order  to  reflect  the  uncertainty  inherent  in  the  projections,  we
performed  our  own  sensitivity  analyses  by  increasing  or  decreasing  the  significant  assumptions  and  evaluated  the  potential
impact on the fair value. In addition, we tested the reconciliation of the fair value of the reporting unit developed by management
to  the  market  capitalization  of  the  Company  as  of  the  valuation  date  and  evaluated  the  implied  control  premium  for
reasonableness.

NOTE 1 — DESCRIPTION OF BUSINESS:

We  develop  and  commercialize  point-of-care  diagnostic  tests  used  for  the  rapid  detection  and  diagnosis  of  infectious  diseases,  including  sexually
transmitted disease, insect vector and tropical disease, COVID-19 and other viral and bacterial infections, enabling expedited treatment.

Our  product  portfolio  is  based  upon  our  proprietary  DPP  technology,  a  diagnostic  platform  that  provides  high-quality,  cost-effective  results  in  15  to  20
minutes  using  fingertip  blood,  nasal  swabs  and  other  sample  types.  The  DPP  technology  platform  addresses  the  rapid  diagnostic  test  market,  which
includes  infectious  diseases  such  as  STI's  and  HIV,  Gastroenterology  and  Women's  Health.  Compared  with traditional lateral flow technology, the DPP
technology platform can provide:

•

•

Enhanced sensitivity and specificity: This is achieved via our patented  approach  to  separating  the  sample  path  from  the  buffer  path,  together
with other patented and proprietary strategies, that differ significantly from traditional lateral flow test.

Advanced  multiplexing  capabilities:  Through  advanced  multiplexing,  the  DPP  platform  can  detect  and  differentiate  up  to  eight  distinct  test
results from a single patient sample, which can deliver greater clinical value than other rapid tests currently on the market.

• Objective results: For some diagnostic applications, our easy-to-use, highly portable, battery-operated DPP Micro Reader optical analyzers can
report accurate results in approximately 15 seconds, making it well-suited for decentralized testing where real-time results enable patients to be
clinically  assessed  while  they  are  still  onsite.  Objective  results  produced  by  the  DPP  Micro  Reader  can  reduce  the  possibility  of  the  types  of
human error that can be experienced in the visual interpretations required by many rapid tests.

We target the market for rapid diagnostic test solutions for infectious diseases, which is 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.  We  have  a  broad  portfolio  of  infectious
disease products, which prior to 2020 were focused principally on sexually transmitted disease and fever and tropical disease. In February 2020 we began
the  process  of  shifting  substantially  all  of  our  resources  to  seek  to  leverage  the  DPP  technology  platform  to  address  the  acute  and  escalating  need  for
diagnostic testing for COVID-19. We are continuing to pursue:

•

•
•

an emergency use authorization, or EUA, from the U.S. Food and Drug Administration, or FDA, as well as 510(k) clearance from the FDA, for
the DPP SARS-CoV-2 Antigen test system;
an EUA from the FDA for the DPP Respiratory Antigen Panel; and
a Clinical Laboratory Improvement Amendment, or CLIA, waiver from the FDA for the DPP HIV-Syphilis test system.

NOTE 2 — SIGNIFICANT ACCOUNTING POLICIES:

(a) Basis of Presentation:

The  accompanying  consolidated  financial  statements  include  the  accounts  of  Chembio  and  its  subsidiaries.  All  significant  intercompany  accounts  and
transactions have been eliminated in consolidation.

Going Concern Considerations

Revenues  during  the  twelve  months  ended  December  31,  2021  did  not  meet  the  Company’s  expectations.  The  Company’s  increase  in  cash  and  cash
equivalents over the year reflected its issuance of common stock in at-the-market offerings for net proceeds of $38.8 million (see Note 9 - Stockholder's
Equity). The Company continued to experience market, clinical trial and regulatory complications in seeking to develop and commercialize a portfolio of
COVID-19  test  systems  during  the  continuing,  but  evolving,  uncertainty  of  the  COVID‑19  pandemic.  For  the  year  ending  December  31,  2021,  the
Company  continued  to  incur  significant  expenses  in  connection  with  pending  legal  matters  (see  Note  12  –  Commitments,  Contingencies,  and
Concentrations:  Litigation),  delayed  achievement  of  milestones  associated  with  government  grant  income,  investments  in  inventory,  and  the  continuing
automation of manufacturing.

The Company performed an assessment to determine whether there were conditions or events that, considered in the aggregate, raised substantial doubt
about the Company’s ability to continue as a going concern within one year after the date the accompanying consolidated financial statements are being
issued. Initially, this assessment did not consider the potential mitigating effect of management’s plans that had not been fully implemented. Because, as
described below, substantial doubt was determined to exist as the result of this initial assessment, management then assessed the mitigating effect of its
plans  to  determine  if  it  is  probable  that  the  plans  (1)  would  be  effectively  implemented  within  one  year  after  the  date  the  accompanying  consolidated
financial statements are issued and (2) when implemented, would mitigate the relevant conditions or events that raise substantial doubt about the entity’s
ability to continue as a going concern.

During the twelve months ended December 31, 2021, the Company undertook measures to increase its total revenues and improve its liquidity position. In
particular,  the  Company  received  significant  purchase  orders  from  two  customers  (the  “July  Purchase  Orders”).  The  Company  had  pursued  the  July
Purchase Orders for an extended period of time. The July Purchase Orders consist of the following:

•

•

On July 20, 2021, the Company received a $28.3 million purchase order from Bio-Manguinhos for the purchase of DPP SARS-CoV-2 Antigen tests
for  delivery  during  2021  to  support  the  urgent  needs  of  Brazil’s  Ministry  of  Health  in  addressing  the  COVID-19  pandemic.  Bio-Manguinhos  is
responsible for the development and production of vaccines, diagnostics and biopharmaceuticals, primarily to meet the demand of Brazil’s national
public health system. As of December 31, 2021 $16.8 million was recognized in connection with this order.

On July 22, 2021, the Company received a $4 million purchase order from the Partnership for Supply Chain Management, supported by The Global
Fund,  for  the  purchase  of  HIV  1/2  STAT-PAK  Assays  for  shipment  to  Ethiopia  into  early  2022.  As  of  December  31,  2021  $1.2  million  was
recognized in connection with this order.

These measures and other plans and initiatives have been designed to provide the Company with adequate liquidity to meet its obligations for at least the
twelve-month period following the date the accompanying audited consolidated financial statements are being issued. The Company’s execution of those
measures and its other plans and initiative continue to depend, however, on factors and uncertainties that are beyond the Company’s control, or that may not
be addressable on terms acceptable to the Company or at all. The Company considered in particular how:

F-8

 
Table of Contents

•

•

The ongoing healthcare and economic impacts of the COVID-19 pandemic on the global customer base for the Company’s non‑COVID-19 products
continue  to  negatively  affect  the  timing  and  rate  of  recovery  of  the  Company’s  revenues  from  those  products  by,  for  example,  decreasing  the
allocation of funding for HIV testing, thereby continuing to adversely affect the Company’s liquidity.

Although  the  Company  has  entered  into  agreements  to  distribute  third-party  COVID-19  products  in  the  United  States,  its  ability  to  sell  those
products could be constrained because of staffing and supply chain limitations affecting the suppliers of those products.

The Company further considered how these factors and uncertainties could impact its ability over the next year to meet the obligations specified in the
Credit Agreement  with  the  Lender  (each  as  defined  in  Note  13  –  Long-Term  Debt).  Those  obligations  include  covenants  requiring:  i)  minimum  cash
balance of $3.0 million and ii) minimum total revenue amounts for the twelve months preceding each quarter end. For the next year, the minimum total
revenue requirements range from $42.0 million for the twelve months ending March 31, 2022 to $47.4 million for the twelve months ending December 31,
2022. Upon an event of default under the Credit Agreement, the Lender could elect to declare all amounts outstanding thereunder, together with accrued
interest, to be immediately due and payable. In such an event, there can be no assurance that the Company would have sufficient liquidity to fund payment
of the amounts that would be due under the Credit Agreement or that, if such liquidity were not available, the Company would be successful in raising
additional capital on acceptable terms, or at all, or in completing any other endeavor to continue to be financially viable and continue as a going concern.
The Company’s inability to raise additional capital on acceptable terms in the near future, whether for purposes of funding payments required under the
Credit  Agreement  or  providing  additional  liquidity  needed  for  its  operations,  could  have  a  material  adverse  effect  on  its  business,  prospects,  results  of
operations, liquidity and financial condition.

Accordingly, management determined the Company could not be certain that the Company’s plans and initiatives would be effectively implemented within
one  year  after  the  date  on  which  the  accompanying  consolidated  financial  statements  are  being  issued.  Without  giving  effect  to  the  prospect  of  raising
additional capital pursuant to the ATM Agreement (as defined in Note 9 – Stockholders’ Equity: Common Stock), increasing product revenue in the near
future  or  executing  other  mitigating  plans,  many  of  which  are  beyond  the  Company’s  control,  it  is  unlikely  that  the  Company  will  be  able  to  generate
sufficient cash flows to meet its required financial obligations, including its debt service and other obligations due to third parties. The existence of these
conditions raises substantial doubt about the Company’s ability to continue as a going concern for the twelve-month period following the date on which the
accompanying audited consolidated financial statements are being issued.

The  accompanying  audited  consolidated  financial  statements  have  been  prepared  assuming  the  Company  will  continue  as  a  going  concern,  which
contemplates continuity of operations, realization of assets and the satisfaction of liabilities in the normal course of business for the twelve-month period
following the date the accompanying consolidated financial statements are issued. As such, the accompanying audited consolidated financial statements do
not  include  any  adjustments  relating  to  the  recoverability  and  classification  of  assets  and  their  carrying  amounts,  or  the  amount  and  classification  of
liabilities that may result should the Company be unable to continue as a going concern.

(b) Use of Estimates:

The  preparation  of  the  consolidated  financial  statements  in  conformity  with  accounting  principles  generally  accepted  in  the  United  States  requires
management  to  make  assumptions  and  estimates  that  affect  the  amounts  reported  in  the  consolidated  financial  statements  and  accompanying  notes.
Judgments  and  estimates  of  uncertainties  are  required  in  applying  the  Company’s  accounting  policies  in  certain  areas.  Generally,  matters  subject  to
estimation  and  judgment  include  accounts  receivable  realization,  inventory  obsolescence,  asset  impairments,  recognition  of  revenue,  useful  lives  of
intangible and fixed assets, stock-based compensation, and deferred tax asset  valuation  allowances.  Due  to  the  inherent  uncertainty  involved  in  making
estimates, actual results reported in future periods may be based upon amounts that differ from those estimates.

(c) Fair Value of Financial Instruments:

The carrying value for cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate fair value due to the immediate
or short-term maturity of these financial instruments. Included in cash and cash equivalents is $25.0 million and $16.0 million as of December 31, 2021 and
2020, respectively, of money market funds that are Level 1 fair value measurements under the hierarchy. The fair value of the Company’s total debt of $20
million (carrying value of $18.8 million) and $20 million (carrying value of $18.2 million) as of December 31, 2021 and 2020, respectively, is a Level 2
fair value measurement under the hierarchy, and the carrying value approximates fair value.

Fair value measurements of all financial assets and liabilities that are being measured and reported on a fair value basis are required to be classified and
disclosed in one of the following three categories:

Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

Level 2: Quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the

asset or liability; and

Level 3:

Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by
little or no market activity).

(d) Cash and Cash Equivalents:

Cash and cash equivalents are defined as short-term, highly liquid investments with original maturities of three months or less at date of purchase.

As of December 31, 2020, the Company was contractually obligated to maintain a restricted cash balance of $1 million on deposit with a bank as security
for the bank’s issuance of a guarantee on behalf of the Company for its performance under purchase orders from which the Company received advance
payments by a customer. The Company has fully performed under the purchase order as of December 31, 2021.

(e) Concentrations of Credit Risk:

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and trade receivables. The Company
places its cash with well-known financial institutions and, at times, may maintain balances in excess of the FDIC insurance limit.

(f) Inventory:

Inventories are stated at the lower of cost or net realizable value with cost being determined using a standard cost method, which approximates average
cost. Average cost consists primarily of material, labor and manufacturing overhead expenses (including fixed production-overhead costs). The Company
analyzes  its  inventory  levels  quarterly  and  writes  down,  in  the  applicable  period,  inventory  that  has  become  obsolete, inventory that has a cost basis in
excess of its expected net realizable value and inventory in excess of expected customer demand. 

F-10

Table of Contents

(g) Fixed Assets:

Fixed assets are stated at cost, less accumulated depreciation.  Depreciation is computed using the straight-line method over the estimated useful lives of
the respective  assets,  which  range  from  three  to  seven  years.  Leasehold  improvements  are  amortized  over  the  useful  life  of  the  asset  or  the  lease  term,
whichever is shorter. Deposits paid for fixed assets are capitalized and not depreciated until the related asset is placed in service.

(h) Valuation of Long-Lived Assets and Intangible Assets:

Long-lived assets to be held and used are analyzed for impairment whenever events or changes in circumstances indicate that the related carrying amounts
may  not  be  recoverable.  The  Company  evaluates  at  each  balance  sheet  date  whether  events  and  circumstances  have  occurred  that  indicate  possible
impairment.  If  there  are  indications  of  impairment,  the  Company  uses  future  undiscounted  cash  flows  of  the  related  asset  or  asset  grouping  over  the
remaining life in measuring whether the assets are recoverable.  In the event such cash flows are not expected to be sufficient to recover the recorded asset
values, the assets are written down to their estimated fair value. A $3.3 and $0 million impairment of long-lived intangible assets was recorded for the years
ended December 31, 2021 and 2020 (see Note 14 - Asset Impairment, Restructuring, Severance and related costs).

(i) Revenue Recognition:

The  Company  recognizes  revenue  when  the  customer  obtains  control  of  promised  goods  or  services,  in  an  amount  that  reflects  the  consideration  the
Company expects to receive in exchange for those goods or services. The Company recognizes revenue following the five-step model prescribed under
Accounting  Standards  Update  (“ASU”)  2014-09:  (i)  identify  contract(s)  with  a  customer;  (ii)  identify  the  performance  obligations  in  the  contract;  (iii)
determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the
Company satisfies the performance obligation.

Product Revenue

Revenue from product sales are recognized and commissions are accrued when the customer obtains control of the Company’s product, which occurs at a
point in time, typically upon tendering the product to the customer. The Company expenses incremental costs of obtaining a contract as and when incurred
because the expected amortization period of the asset that it would have recognized is one year or less or the amount is immaterial. Freight and distribution
activities on products are performed when the customer obtains control of the goods. The Company has made an accounting policy election to account for
shipping and handling activities that occur either when or after goods are tendered to the customer as a fulfillment activity, and therefore recognizes freight
and distribution expenses in cost of product sales. The Company excludes certain taxes from the transaction price (e.g., sales, value added and some excise
taxes).

The Company’s contracts with customers often include promises to transfer products or services to a customer. Determining whether products and services
are considered distinct performance obligations that should be accounted for separately versus together may require judgment. Typical products sold are
diagnostic tests and typical services performed are R&D studies. Revenues from product sales are recognized at a point-in-time and revenues from R&D
studies are recognized ratably over the period of the agreement, unless the related performance obligations indicate otherwise.

Judgment  is  required  to  determine  the  stand-alone  selling  price  (“SSP”)  for  each  distinct  performance  obligation.  SSP  is  directly  observable  and  the
Company can use a range  of  amounts  to  estimate  SSP,  as  it  sells  products  and  services  separately,  and  can  determine  whether  there  is  a  discount  to  be
allocated based on the relative SSP of the various products and services, for the various geographies.

F-11

Table of Contents

From time to time the Company engages in bill-and-hold arrangements, whereby the Company manufactures and sells its product and at the customer’s
request stores the product at the Company’s warehouse. Even though the product remains in the Company’s possession, a sale is recognized at the point in
time  when  the  customer  obtains  control  of  the  product.  Control  is  transferred  to  the  customer  in  bill  and  hold  transactions  when:  customer acceptance
specifications have been met, legal title has transferred, the customer has a present obligation to pay for the product and the risk and rewards of ownership
have transferred to the customer.  Additionally, all the following bill and hold criteria would have to be met in order for control to be transferred to the
customer: 

(a) The reason for the bill-and-hold arrangement must be substantive (for example, the customer has requested the arrangement).
(b) The product must be identified separately as belonging to the customer.
(c) The product currently must be ready for physical transfer to the customer.
(d) The entity cannot have the ability to use the product or to direct it to another customer.

The  Company’s  payment  terms  vary  by  the  type  and  location  of  the  Company’s  customer  and  products  or  services  offered.  Payment  terms  differ  by
jurisdiction and customer, but payment is generally required in a term ranging from 30 to 60 days from date of shipment or satisfaction of the performance
obligation.

Reserves for Discounts and Allowances

Revenue  from  product  sales  are  recorded  net  of  reserves  established  for  applicable  discounts  and  allowances  that  are  offered  within  contracts  with  the
Company’s customers.

Product  revenue  reserves,  which  are  classified  as  a  reduction  in  product  revenue,  are  generally  related  to  discounts  and  returns.  Estimates  of  variable
consideration and the determination of whether to include estimated amounts in the transaction price are based on all information (historical, current, and
forecasted) that is reasonably available to the Company, taking into consideration the type of customer, the type of transaction, market events and trends,
and  the  specific  facts  and  circumstances  of  each  arrangement.  The  transaction  price,  which  includes  variable  consideration  reflecting  the  impact  of
discounts, allowances and returns may be subject to constraint and is included in the net sales price only to the extent that it is probable that a significant
reversal of the amount of the revenue recognized will not occur in a future period. Actual amounts may ultimately differ from the Company’s estimates. If
actual results vary, the Company adjusts these estimates, which could have an effect on revenue and earnings in the period of adjustment.

License and Royalty Revenues

The Company receives royalty revenue on sales by its licensee of products covered under patents that the Company owns. The Company does not have
future  performance  obligations  under  this  license  arrangement.  The  Company  records  revenue  based  on  estimates  of  the  sales  that  occurred  during  the
relevant period as a component of license and royalty revenue. The relevant period estimates of sales are based on interim data provided by the licensee and
analysis  of  historical  royalties  that  have  been  paid  to  the  Company,  adjusted  for  any  changes  in  facts  and  circumstances,  as  appropriate.  Differences
between  actual  and  estimated  royalty  revenue  are  adjusted  for  in  the  period  in  which  they  become  known,  typically  the  following  quarter.  Historically,
adjustments have not been material when compared to actual amounts paid by licensees.

R&D Revenue

All contracts with customers are evaluated under the five-step model described above.  Such contracts are further described in Note 7 -  Revenue. Grants
are invoiced and revenue is recognized ratably as that is the depiction of the timing of the transfer of services. The R&D study, which encompasses various
phases  of  product  development  processes:  design  feasibility  &  planning,  product  development  and  design  optimization,  design  verification,  design
validation and process validation, and pivotal studies, is also recognized ratably.

For certain contracts that represent non-governmental grants where the funder does not meet the definition of a customer, the Company recognizes revenue
when earned in accordance with Accounting Standards Codification (“ASC”) Topic 958.

Government Grant Income

Chembio receives government grants in support of R&D activities that are not associated with a customer-vendor relationship and therefore falls outside
the scope of ASC 606. Because there is no authoritative guidance under U.S. GAAP on accounting for government grants received, Chembio applies Topic
958 - Not-for-profit entities guidance by analogy. In June 2018, the Financial Accounting Standards Board (the “FASB”) issued ASU 2018-08, Not-for-
Profit Entities (Topic 958): Clarifying the Scope and the Accounting Guidance for Contributions Received and Contributions Made. This ASU clarifies the
guidance presented in ASC Topic 958, “Not-for-Profit Entities,” for evaluating whether a transaction is reciprocal (i.e., an exchange transaction) or non
reciprocal (i.e., a contribution) and for distinguishing between conditional and unconditional contributions. The ASU also clarified the guidance used by
entities other than not-for-profits to identify and account for contributions made. Government grants are invoiced and revenue is recognized as milestones
are achieved, conditions are removed and approval from grantor is obtained.

In July 2020, the Company was awarded a grant of $0.6 million from BARDA to develop a SARS-CoV-2 Ag System. The Company earned $0.2 and $0.4
million for the years ended December 31, 2021 and 2020, respectively, and was recorded as government grant income.  

In December 2020, the Company was awarded a grant of $12.7 million from BARDA to support the development and pursuit of FDA EUA for a rapid,
multiplex DPP Respiratory Antigen Panel point-of-care test system. The Company earned $10.9 and $1.6 million for the years ended December 31, 2021
and 2020, respectively, and was recorded as government grant income. Culmulative through December 31, 2021, the Company recognized $12.5 million
under this agreement, and the remainder $0.2 million is subject to obtaining the EUA for the DPP SARs-COV-2 Antigen test.

Contract Liabilities

Deferred revenue relates to payments received in advance of performance under the contract. Deferred revenue is recognized as revenue as (or when) the
Company performs under the contract. At December 31, 2020, the Company reported $1.6 million in deferred revenue of which $1.6 million was earned
and recognized as product sales during the year ended December 31, 2021. At December 31, 2021, the Company reported $0 in deferred revenue.

(j) Loss Per Share:

Basic loss per share is computed by dividing net loss by the weighted average number of common stock shares outstanding during the period. Diluted net
loss per share is computed using the treasury stock method if the additional shares are dilutive. For all periods presented, basic and diluted net loss per
share are the same as any additional shares would be anti-dilutive.

There  were  705,325  and  603,531  restricted  shares  awards  outstanding  as  of  December  31,  2021  and  2020,  respectively,  that  were  not  included  in  the
calculation of diluted income per share for the year ended December 31, 2021 and 2020, because their effect would have been anti-dilutive. There were
1,600,372 and 974,778 options outstanding as of December 31, 2021 and 2020 respectively, that were not included in the calculation of diluted income per
share for the twelve months ended December 31, 2021 and 2020, respectively, because their effect would have been anti-dilutive.

(k) Research and Development:

Research  and  Development  (R&D)  include  product  development,  program  management,  clinical  trials  and  regulatory  costs  and  are  expensed  when
incurred. Advance payments for goods and services that will be used in future research and development activities are expensed when the activity has been
performed or when the goods have been received rather than when the payment is made.

(l) Stock-Based Compensation:

The Company grants share options to employees and non-employee members of the Company’s board of directors as compensation for services performed.
Employee  and  non-employee  members  of  the  board  of  directors’  awards  of  share-based  compensation  are  accounted  for  in  accordance  with  ASC  718,
Compensation - Stock Compensation, or ASC 718. ASC 718 requires all share-based payments to employees and non-employee directors, including grants
of share options, to be recognized in the consolidated statement of operations and comprehensive loss based on their grant date fair values.

F-13

 
  
Table of Contents

The  grant  date  fair  value  of  share  options  is  estimated  using  the  Black-Scholes  option  valuation  model.  The  fair  value  of  restricted  stock  and
performance/restricted stock unit awards are determined on the date of grant or the date of issuance, as applicable.

The  grant  date  fair  value  is  calculated  based  on  assumptions  with  respect  to  (i)  the  fair  value  of  the  Company’s  common  stock  on  the  grant  date;  (ii)
expected volatility of  the  Company’s  common  stock  price,  (iii)  the  periods  of  time  over  which  the  optionees  are  expected  to  hold  their  options  prior  to
exercise (expected term), (iv) expected dividend yield on the Company’s common stock, and (v) risk-free interest rates.

The expected volatility is calculated based on historical data of the Company's common stock. The expected dividend yield is zero as the Company has
never paid dividends and does not currently anticipate paying any in the foreseeable future. Risk-free interest rates are based on quoted U.S. Treasury rates
for securities with maturities approximating the option’s expected term. The expected term of share options granted to the optionees is determined using the
average of the vesting period and contractual life of the option.

Stock based compensation is generally recognized on a straight-line basis over the service period of the grant and is reduced for actual forfeitures in the
period in which the forfeiture occurs.

(m) Income Taxes:

The Company accounts for income taxes under an asset and liability approach that recognizes deferred tax assets and liabilities based on the difference
between  the  financial  statement  carrying  amounts  and  the  tax  bases  of  assets  and  liabilities  using  enacted  tax  rates  in  effect  in  the  years  in  which  the
differences are expected to reverse.

The  Company  follows  a  more-likely-than-not  threshold  for  financial  statement  recognition  and  measurement  of  a  tax  position  taken,  or  expected  to  be
taken, in a tax return. The guidance relates to, among other things, classification, accounting for interest and penalties associated with tax positions, and
disclosure requirements. Any interest and penalties accrued related to uncertain tax positions are recorded in tax expense.

The Company assesses the realizability of its net deferred tax assets on an annual basis. If, after considering all relevant positive and negative evidence, it is
more likely than not that some portion or all of the net deferred tax assets will not be realized, the Company will reduce the net deferred tax assets by a
valuation allowance. The realization of net deferred tax assets is dependent on several factors, including the generation of sufficient taxable income prior to
the expiration of net operating loss carryforwards.

(n) Goodwill

Goodwill represents the excess of the purchase price the Company paid over the fair value of the net tangible and identifiable intangible assets acquired in
the Company’s acquisition. Goodwill is not amortized but rather is tested annually as of the first day of the fiscal fourth quarter, or sooner if the Company
believes that indicators of impairment exist. The Company makes a qualitative evaluation about the likelihood of goodwill impairment, which is based on a
number of applicable factors. If the Company concludes that it is more likely than not that the carrying value of the applicable reporting unit is greater than
its fair value, then it would recognize an impairment charge for the amount by which the carrying value exceeds the reporting unit’s fair value, provided the
impairment charge does not exceed the total amount of goodwill allocated to the reporting unit.

The  quantitative  goodwill  impairment  test  is  performed  using  a  one-step  process.  The  process  is  to  compare  the  fair  value  of  a  reporting  unit  with  its
carrying amount. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is not impaired. If the carrying amount of a
reporting unit exceeds its fair value, goodwill of the reporting unit is impaired and an impairment loss is recognized in an amount equal to that excess.

The company operates as a single operating segment and has one reporting unit. During the year ended December 31, 2021, the Company performed a
quantitative analysis and determined that the carrying value exceeded its fair value by $2.6 million, on December 31, 2021 and recorded an impairment
charge.

F-14

Table of Contents

(o) Allowance for Doubtful Accounts:

The  Company  records  allowances  for  doubtful  accounts  for  the  estimated  probable  losses  on  uncollectible  accounts  receivable.  The  allowance  is  based
upon the credit worthiness of the Company’s customers, the Company’s historical experience, the age of the receivable and current market and economic
conditions. Receivables are written off against these allowances in the period they are determined to be uncollectible.

(p) Acquisition Costs:

Acquisition costs are expensed when incurred and include primarily professional services, related to acquisition activities.

(q) Foreign Currency Translation:

The functional currency of a foreign subsidiary is the local currency. Assets and liabilities of foreign subsidiaries that use a currency other than U.S. dollars
as their functional currency are translated to U.S. dollars at end of period currency exchange rates. The consolidated statements of operations of foreign
subsidiaries are translated to U.S. dollars at average period currency exchange rates. The effect of translation for foreign subsidiaries is generally reported
in other comprehensive income.

(r) Leases:

The Company accounts for leases in accordance with ASC 842. The Company determines if an arrangement is a lease at contract inception. A lease exists
when a contract conveys  the  right  to  control  the  use  of  identified  property,  plant,  or  equipment  for  a  period  of  time  in  exchange  for  consideration.  The
definition of a lease embodies two conditions: (1) there is an identified asset in the contract that is land or a depreciable asset (i.e., property, plant, and
equipment), and (2) the Company has the right to control the use of the identified asset. The Company accounts for the lease and non-lease components as a
single lease component.

From time to time the Company enters into direct financing lease arrangements that include a lessee obligation to purchase the leased asset at the end of the
lease term, a bargain purchase option, or provides for minimum lease payments with a present value of 90% or more of the fair value of the leased asset at
the date of lease inception.

Operating  leases  where  the  Company  is  the  lessee  are  included  in  right-of-use  (“ROU”)  assets  and  lease  obligations  are  included  on  the  Company’s
consolidated balance sheets. The lease obligations are initially and subsequently measured at the present value of the unpaid lease payments at the lease
commencement date and subsequent reporting periods.

Finance leases where the Company is the lessee are included in ROU assets and lease obligations on the Company’s consolidated balance sheets. The lease
obligations are initially measured in the same manner as for operating leases and are subsequently measured at amortized cost using the effective interest
method.

Key estimates and judgments include how the Company determined (1) the discount rate used to discount the unpaid lease payments to present value, (2)
lease term and (3) lease payments. ASC 842 requires a lessee to discount its unpaid lease payments using the interest rate implicit in the lease or, if that rate
cannot be readily determined, its incremental borrowing rate. As most of the Company’s leases where it is the lessee do not provide an implicit rate, the
Company  uses  its  incremental  borrowing  rate  based  on  the  information  available  at  commencement  date  in  determining  the  present  value  of  lease
payments. The Company’s incremental borrowing rate for a lease is the rate of interest it would have to pay on a collateralized basis to borrow an amount
equal to the lease payments under similar terms. The Company uses the implicit rate when readily determinable.

F-15

Table of Contents

The lease term for all of the Company’s leases includes the noncancelable period of the lease plus any additional periods covered by either a lessee option
to extend (or not to terminate) the lease that is reasonably certain to be exercised, or an option to extend (or not to terminate) the lease controlled by the
lessor.

The ROU asset is initially measured at cost, which comprises the initial amount of the lease liability adjusted for lease payments made at or before the lease
commencement  date  less  any  lease  incentives  received.  For  operating  leases,  the  ROU  asset  is  subsequently  measured  throughout  the  lease  term  at  the
carrying amount of the lease liability, minus any accrued lease payments, less the unamortized balance of lease incentives received. Lease expense for lease
payments is recognized on a straight-line basis over the lease term.

For finance leases, the ROU asset is subsequently amortized using the straight-line method from the lease commencement date to the earlier of the end of
its useful life or the end of the lease term unless the lease transfers ownership of the underlying asset, or the Company is reasonably certain to exercise an
option to purchase the underlying asset. In those cases, the ROU asset is amortized over the useful life of the underlying asset. Amortization of the ROU
asset is recognized and presented separately from interest expense on the lease liability.

The Company has elected not to recognize ROU assets and lease liabilities for all short-term leases that have a lease term of 12 months or less at lease
commencement. Lease payments associated with short-term leases are recognized as an expense on a straight-line basis over the lease term.

Impairment charges for the Malaysian facility right-of-use asset recorded during the years ended December 31, 2021 was $0.1 and $0 million, respectively
(see Note 14 - Asset Impairment, Restructuring, Severance and related costs).

(s) Recent Accounting Pronouncements Affecting the Company:

Recently Adopted

ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes

In December  2019,  the  FASB  issued  ASU  2019-12.  This  standard  simplifies  the  accounting  for  income  taxes  by  eliminating  certain  exceptions  to  the
guidance in Topic 740 related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the
recognition  of  deferred  tax  liabilities  for  outside  basis  differences.  The  new  guidance  also  simplifies  aspects  of  the  accounting  for  franchise  taxes  and
enacted  changes  in  tax  laws  or  rates  and  clarifies  the  accounting  for  transactions  that  result  in  a  step-up  in  the  tax  basis  of  goodwill  and  allocating
consolidated income taxes to separate financial statements of entities not subject to income tax. ASU 2019-12 is effective for fiscal years beginning after
December 15, 2020, with early adoption permitted. Upon adoption, the Company must apply certain aspects of this standard retrospectively for all periods
presented while other aspects are applied on a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning
of the fiscal year of adoption. The Company adopted the standard effective January 1, 2021 and has determined that the adoption did not have a material
impact on the Company’s consolidated financial statements.

ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting

In March 2020, the FASB issued ASC Topic 848. ASC Topic 848 provides relief for impacted areas as it relates to impending reference rate reform. ASC
Topic  848  contains  optional  expedients  and  exceptions  for  applying  GAAP  to  debt  arrangements,  contracts,  hedging  relationships,  and  other  areas  or
transactions that are impacted by reference rate reform. This guidance is effective upon issuance for all entities and elections of certain optional expedients
are required to apply the provisions of the guidance. The Company adopted the standard effective January 1, 2021 and has determined that the adoption did
not have a material impact on the Company’s consolidated financial statements.

Not Yet Adopted

ASU 2021-10 - Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance

In November 2021, the FASB issued ASU 2021-10, Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance,
which  aims  to  provide  increased  transparency  by  requiring  business  entities  to  disclose  information  about  certain  types  of  government  assistance  they
receive in the notes to the financial statements. The disclosure requirements in ASC 832 only apply to transactions with a government that are accounted
for by analogizing to either a grant model (for example, in International Accounting Standard (IAS) 20, Accounting for Government Grants and Disclosure
of Government Assistance), or a contribution model (for example, in ASC 958-605, Not-for-Profit Entities – Revenue Recognition). The FASB broadly
defined  “government  assistance”  in  ASC  832  to  ensure  that  assistance  received  from  most  types  of  governmental  entities  or  other  related  organizations
would be disclosed.  Entities are required to provide the new disclosures prospectively for all transactions with a government entity that are accounted for
under either a grant or a contribution accounting model and are reflected in the financial statements at the date of initially applying the new amendments,
and to new transactions entered into after that date. Retrospective application of the guidance is permitted. The guidance in ASU 2021-10 is effective for
financial  statements  of  all  entities,  for  annual  periods  beginning  after  December  15,  2021,  with  early  application  permitted.  The  Company  continues  to
assess all potential impact of the standard and will disclose the nature and reason for any elections that the Company makes.

ASU  2020-06  -  Debt—Debt  with  Conversion  and  Other  Options  (Subtopic  470-20)  and  Derivatives  and  Hedging—Contracts  in  Entity’s  Own  Equity
(Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity
20

On August 5, 2020, the FASB issued ASU 2020-06, which simplifies the accounting for certain financial instruments with characteristics of liabilities and
equity, including convertible instruments and contracts on an entity’s own equity. The ASU is part of the FASB’s simplification initiative, which aims to
reduce  unnecessary  complexity  in  U.S.  GAAP.  ASU  2020-06  simplifies  the  guidance  in  U.S.  GAAP  on  the  issuer’s  accounting  for  convertible  debt
instruments, requires entities to provide expanded disclosures about “the terms and features of convertible instruments” and how the instruments have been
reported  in  the  entity’s  financial  statements.  It  also  removes  from  ASC  815-40-25-10  certain  conditions  for  equity  classification  and  amends  certain
guidance in ASC 260 on the computation of EPS for convertible instruments and contracts on an entity’s own equity. An entity can use either a full or
modified  retrospective  approach  to  adopt  the  ASU’s  guidance.  The  ASU’s  amendments  are  effective  for  smaller  public  business  entities  fiscal  years
beginning after December 15, 2023. The Company continues to assess the potential impact of the standard and will disclose the nature and reason for any
elections that the Company makes.

ASU 2021-08—Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers

On October 28, 2021, the FASB issued ASU 2021-08,1 which amends ASC 805 to “require acquiring entities to apply Topic 606 to recognize and measure
contract assets and contract liabilities in a business combination.” Under current GAAP, an acquirer generally recognizes such items at fair value on the
acquisition date. ASU 2021-08 amends ASC 805 to add contract assets and contract liabilities to the list of exceptions to the recognition and measurement
principles  that  apply  to  business  combinations  and  to  “require  that  an  entity  (acquirer)  recognize  and  measure  contract  assets  and  contract  liabilities
acquired in a business combination in accordance with Topic 606.” While primarily related to contract assets and contract liabilities that were accounted for
by  the  acquiree  in  accordance  with  ASC  606,  “the  amendments  also  apply  to  contract  assets  and  contract  liabilities  from  other  contracts  to  which  the
provisions  of  Topic  606  apply,  such  as  contract  liabilities  from  the  sale  of  nonfinancial  assets  within  the  scope  of  Subtopic  610-20.”  The  ASU’s
amendments are effective for public business entities for the fiscal years beginning after December 15, 2022, including interim periods within those fiscal
years. The amendments should be applied prospectively to business combinations occurring on or after the effective date of the amendments. The Company
continues to assess the potential impact of the standard and will disclose the nature and reason for any elections that the Company makes.

The Company does not provide for U.S. income taxes on unremitted earnings of foreign subsidiaries as its present intention is to reinvest the unremitted
earnings in the Company’s foreign operations. At December 31, 2021 there were no unremitted earnings of foreign subsidiaries.

Interest and penalties, if any, related to income tax liabilities are included in income tax expense. As of December 31, 2021, the Company does not have
any uncertain tax positions.

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act, (“CARES Act”), was enacted in response to the COVID-19 pandemic. The
CARES Act, among other things, permits NOL carryovers and carrybacks to offset 100% of taxable income for taxable years beginning before 2021. In
addition,  the  CARES  Act  allows  NOLs  incurred  in  tax  years  2018,  2019,  and  2020  to  be  carried  back  to  each  of  the  five  preceding  taxable  years.    In
addition to the NOL changes, the CARES Act contains modifications on the limitation of business interest for tax years beginning in 2019 and 2020. The
modifications to Section 163(j) increase the allowable business interest deduction from 30% of adjusted taxable income to 50% of adjusted taxable income.
This modification did not effect the Company’s interest expense limitation. Overall the CARES ACT did not have a significant impact on the Company
since it maintains a full valuation allowance.

NOTE 12 — COMMITMENTS, CONTINGENCIES AND CONCENTRATIONS:

a) Employment Contracts:

The Company has multi-year contracts with two key employees.  The contracts call for salaries presently aggregating $843,000 per year, and they expire in
December 2022 and December 2025. The following table is a schedule of future minimum salary commitments:

The Company has a 401(k) plan established for its employees whereby it matches 40% of the first 5% (or 2% of salary) that an employee contributes to the
plan.  Matching contribution expenses totaled $138,513 and $87,377 for the years ended December 31, 2021 and 2020, respectively.

c) Leases:

The Company leases facilities in New York, Germany, Malaysia, and Brazil, and certain equipment.

The Company’s facility leases generally include optional renewal periods. Upon entering into a new facility lease, the Company evaluates the leasehold
improvements and regulatory requirements related to its operations in that location. To the extent that the initial lease term of the related facility lease is
less than the useful life of the leasehold improvements and potential regulatory costs associated with moving the facility, the Company concludes that it is
reasonably certain that a renewal option will be exercised, and thus that renewal period is included in the lease term and the related payments are reflected
in the right-of-use asset and lease liability.

The Company’s leases generally include fixed rental payments with defined annual increases. While certain of the Company’s leases are gross leases, the
majority of the Company’s leases are net leases in which the Company makes separate payments to the lessor based on the lessor’s property and casualty
insurance costs, the property taxes assessed on the property, and a portion of the common area maintenance where applicable. The Company has elected the
practical expedient not to separate lease and nonlease components for all of the Company’s facility leases.

The Company purchases materials pursuant to intellectual property rights agreements that are important components in its products.  Management believes
that other suppliers could provide similar materials on comparable terms.  A change in suppliers, however, could cause a delay in manufacturing and a
possible loss of sales, which could adversely affect operating results.

e) Litigation:

SEC Investigation

The SEC is conducting a non-public, fact-finding investigation relating to the public offering of common stock that Chembio completed in May 2020 (the
“May  2020  Offering”)  and  to  the  FDA’s  revocation  in  June  2020  of  an  emergency  use  authorization  for  the  DPP  COVID-19  IgM/IgG  system  that  was
issued  by  the  FDA  in  April  2020.  Chembio  received  subpoenas  from  the  SEC  in  July  2020  and  April  2021  seeking  the  production  of  documents  in
connection with this investigation. In addition, the SEC delivered subpoenas in April 2021 to five of Chembio’s employees (including its three executive
officers, who consist of its Chief Executive Officer and President, its former Executive Vice President and Chief Financial Officer, and its Executive Vice
President and Chief Scientific and Technology Officer). An additional subpoena was issued in June 2021 to Chembio’s former Interim Chief Executive
Officer  and  Executive  Chair.  Each  subpoena  requested  the  production  of  documents  relating  to  the  same  matters  as  are  the  subject  of  the  subpoenas
Chembio received. Chembio and the six individuals are cooperating fully in the SEC’s investigation and expect to continue to do so.

The SEC’s letters transmitting the subpoenas expressly provide that the inquiry does not mean that the SEC or its staff have concluded that anyone has
violated the federal securities laws or have a negative opinion of any person, entity or security. The Company cannot predict the scope, duration or outcome
of the investigation or the impact, if any, of the investigation on its results of operations.

Legal Proceedings

Stockholder Litigation

Putative Stockholder Securities Class-Action Litigation

In  2020  four  purported  securities  class-action  lawsuits  were  filed  in  the  United  States  District  Court  for  the  Eastern  District  of  New  York  by  alleged
stockholders of Chembio:

● Sergey Chernysh v. Chembio Diagnostics, Inc., Richard L. Eberly, and Gail S. Page, filed on June 18, 2020;
● James Gowen v. Chembio Diagnostics, Inc., Richard L. Eberly, and Gail S. Page, filed on June 22, 2020;
● Anthony Bailey v. Chembio Diagnostics, Inc. Richard J. Eberly, Gail S. Page, and Neil A. Goldman, filed on July 3, 2020; and
● Special  Situations  Fund  III  QP,  L.P.,  Special  Situations  Cayman  Fund,  L.P.,  and  Special  Situations  Private  Equity  Fund,  L.P.  v.  Chembio

Diagnostics, Inc., Richard Eberly, Gail S. Page, Robert W. Baird & Co. Inc. and Dougherty & Company LLC, filed August 17, 2020.

Table of Contents

The plaintiffs in each of the above cases alleged claims under Section 10(b) of the Securities Exchange Act of 1934 (the “Exchange Act”), Rule 10b-5
thereunder  and  Section  20(a)  of  the  Exchange  Act.  Special  Situations  Fund  III  QP,  L.P.,  Special  Situations  Cayman  Fund,  L.P.  and  Special  Situations
Private Equity Fund, L.P. (collectively, the “Special Situations Funds”) also asserted claims under Sections 11, 12(a)(2) and 15 of the Securities Act of
1933 (the “Securities Act”) relating to the May 2020 Offering.

Chembio  and  the  plaintiffs  entered  into  Court-approved  stipulations  relieving  Chembio  and  the  other  defendants  of  the  obligation  to  respond  to  the
complaints in these cases pending the designation of a lead plaintiff pursuant to the Private Securities Litigation Reform Act of 1995. Eight motions for
appointment  as  lead  plaintiff  were  filed  by  various  prospective  lead  plaintiffs.  However,  all  but  two  of  these  motions  were  withdrawn  or  otherwise
abandoned,  leaving  before  the  Court  two  motions  for  appointment  as  lead  plaintiff  -  one  filed  by  the  Special  Situations  Funds  and  one  by  Municipal
Employees’ Retirement System of Michigan. By order entered December 29, 2020, Magistrate Judge Lindsay consolidated the cases and appointed the
Special  Situations  Funds  and  Municipal  Employees’  Retirement  System  of  Michigan  (together,  the  “Lead  Plaintiffs”),  as  co-lead  plaintiffs  and  their
respective counsel as co-lead counsel. The consolidated cases are now pending under the caption “In re Chembio Diagnostics, Inc. Securities Litigation.”

The  Lead  Plaintiffs  filed  their  Consolidated  Amended  Complaint  (the  “CAC”)  on  February  12,  2021.  In  summary,  the  CAC  purported  to  allege  claims
based  on  assertedly  false  and  misleading  statements  and  omissions  concerning  the  performance  of  the  DPP  COVID-19  IgM/IgG  System,  as  well  as  an
asserted failure to timely disclose that the emergency use authorization that had been granted by the FDA with respect to the DPP COVID-19 IgM/IgG
System “was - or was at an increased risk of - being revoked.” The CAC named as defendants Chembio, Richard L. Eberly, Gail S. Page, Neil A. Goldman,
Javan Esfandiari, Katherine L. Davis, Mary Lake Polan, John Potthoff and the underwriters for the May 2020 Offering, Robert W. Baird & Co., Inc. and
Dougherty & Company LLC (the “Underwriter Defendants”).

The  CAC  purported  to  assert  five  counts  under  the  Securities  Act  and  the  Exchange  Act.  Counts  I  through  III  were  brought  under  the  Securities  Act,
allegedly on behalf of a purported class consisting of all persons who purchased Chembio common stock directly in or traceable to the May 2020 Offering
pursuant  to  Chembio’s  shelf  registration  statement  on  Form  S  3  (File  No.  333-227398)  and  the  related  prospectus,  as  supplemented  by  a  prospectus
supplement dated May 7, 2020 (the “Securities Act Class”). Count I purported to allege a claim for violation of Section 11 of the Securities Act against all
defendants  other  than  Messrs.  Eberly  and  Esfandiari.  Count  II  purported  to  allege  a  claim  for  violation  of  Section  12  of  the  Securities  Act  against  all
defendants other than Messrs. Eberly and Esfandiari. Count III purported to allege a claim under Section 15 of the Securities Act against Ms. Davis, Dr.
Polan, Dr. Potthoff, Ms. Page and Mr. Goldman.

Counts IV and V alleged claims under the Exchange Act on behalf of a purported class consisting of all persons who purchased Chembio common stock on
the open market from March 12, 2020 through June 16, 2020 (the “Exchange Act Class”). Count IV purported to allege a claim for violation of Section
10(b) of the Exchange Act and Rule 10b-5 thereunder against Chembio, Mr. Eberly, Ms. Page, Mr. Goldman and Mr. Esfandiari. Count V purported to
allege a claim under Section 20(a) of the Exchange Act against Mr. Eberly, Ms. Page, Mr. Goldman and Mr. Esfandiari.

In their CAC, the Lead Plaintiffs sought, on behalf of the Securities Act Class and the Exchange Act Class, among other things, an award of damages in an
amount to be proven at trial, as well as an award of reasonable costs, including attorneys’ fees and expenses, expert fees, pre-judgment and post-judgment
interest, and such other relief as the Court deems just and proper. The Lead Plaintiffs also sought rescission “or a rescissory measure of damages” on behalf
of the Securities Act Class as to Count II.

Table of Contents

Pursuant to an order entered by the Court on January 29, 2021, any defendant wishing to move against the amended complaint was required to file, by
February  18,  2021,  a  letter  requesting  a  pre-motion  conference.  On  that  date,  the  defendants  submitted  letters  to  the  Court  requesting  a  pre-motion
conference regarding anticipated motions to dismiss the CAC, and the Lead Plaintiffs responded on February 24, 2021. In its January 29, 2021 order, the
Court indicated that it would consider a briefing schedule on motions to dismiss after it had received and reviewed the parties’ correspondence.

On  March  5,  2021,  the  Court  entered  an  order  in  which  it  advised  the  parties  that  it  had  determined  a  pre  motion  conference  was  not  necessary  and
established a briefing schedule on the defendants’ anticipated motions to dismiss. However, the defendants subsequently agreed with the Lead Plaintiffs’
counsel to a modification of the schedule, which was then approved by the Court. Pursuant to that schedule, defendants’ motions and supporting papers
were filed on March 26, 2021, the Lead Plaintiffs’ opposition papers were filed on April 16, 2021, and the defendants’ reply papers were filed on April 30,
2021.

The Court issued its Opinion and Order (the “Order”) on the defendants’ motions to dismiss on February 23, 2022.  In its Order, the Court: (i) dismissed
Counts  I  and  II  without  prejudice  as  to  all  defendants  named  in  those  Counts  except  the  Underwriter  Defendants  as  to  which  Counts  I  and  II  were  not
dismissed; (ii) dismissed Count III without prejudice as to all defendants named in that Count; and (iii) dismissed Counts IV and V with prejudice as to all
defendants named in those Counts.  The Court gave Lead Plaintiffs fourteen days within which to attempt to replead their claims under the Securities Act
against Chembio, Ms. Page, Mr. Goldman, Ms. Davis, Ms. Polan and Mr. Potthoff.

Putative Stockholder Derivative Litigation

On September 11, 2020, a putative stockholder derivative action captioned Karen Wong, derivatively on behalf of Chembio Diagnostics, Inc., Plaintiff v.
Richard L. Eberly, Gail S. Page, Neil A. Goldman, Javan Esfandiari, Katherine L. Davis, Mary Lake Polan and John G. Potthoff, Defendants, and Chembio
Diagnostics,  Inc.,  Nominal  Defendant  (the  “Wong  complaint”)  was  filed  purportedly  on  Chembio’s  behalf  in  the  United  States  District  Court  for  the
Eastern District of New York. The Wong complaint purports to assert a claim for violation of Section 14(a) of the Exchange Act and Rule 14a-9 thereunder
based  on  ostensibly  false  and  misleading  statements  and  omissions  concerning  the  Company’s  rapid  COVID-19  antibody  test  in  the  proxy  statement
disseminated  in  advance  of  Chembio’s  Annual  Meeting  of  Stockholders  held  on  July  28,  2020.  The  Wong  complaint  also  asserts  claims  against  the
individual defendants for purported breaches of fiduciary duties owed to Chembio, as well as unjust enrichment.

The  Wong  complaint  requests  a  declaration  that  the  individual  defendants  have  breached  or  aided  and  abetted  the  breach  of  their  fiduciary  duties  to
Chembio, an award of damages to us, restitution, and an award of the plaintiff’s costs and disbursements in the action, including reasonable attorneys’ and
experts’ fees, costs and expenses, and improvements to Chembio’s corporate governance and internal procedures regarding compliance with laws. Pursuant
to a stipulation by which the individual defendants named in the Wong complaint agreed to waive service of process, the Court ordered that the time for
defendants to answer or otherwise respond to the complaint be extended to November 19, 2020. The parties subsequently entered into a stipulation for a
stay of proceedings in the action relating to the Wong complaint pending final disposition of motions to dismiss the pending putative class-action litigation,
subject to certain conditions. The Court entered an order granting the requested stay on November 3, 2020. At this stage of the litigation, the Company is
not able to predict the probability of a favorable or unfavorable outcome.

Employee Litigation

On March 19, 2021, John J. Sperzel III, Chembio’s former chief executive officer, filed a fifteen-count complaint in the United States District Court for the
Eastern District of New York. The complaint was filed following the dismissal of an action previously filed by Mr. Sperzel in the United States District
Court in Maine, which was dismissed for lack of personal jurisdiction over Chembio. In summary, the complaint filed in the Eastern District of New York
alleges that Chembio wrongfully refused to allow Mr. Sperzel to exercise certain options to purchase, for an aggregate exercise price of $943,126, a total of
266,666 shares of common stock that were allegedly vested as of the date of his separation from Chembio, on January 3, 2020. The complaint alleges that
under the terms of the applicable stock incentive plans, Mr. Sperzel had thirty days after the date on which he ceased to qualify as an “Eligible Person”
under the plans within which to exercise the options, and asserts that by reason of his alleged continued service to us, he remained an “Eligible Person” and
ostensibly retained the right to exercise the options. The Compensation Committee of the Board determined that the options expired on February 3, 2020,
thirty days after Mr. Sperzel’s separation from Chembio, and that a purported attempt by Mr. Sperzel to exercise the options after that date was not valid.

F-30

Table of Contents

Count  I  of  the  complaint  purports  to  allege  that  Chembio  breached  Mr.  Sperzel’s  separation  agreement  by  refusing  to  allow  him  to  exercise  the  stock
options. Counts II through XI of the complaint purport to allege claims for breach of each of ten separate stock option agreements, collectively asserting
damages of “at least” $3,190,198. Count XII of the complaint alleges a breach of Mr. Sperzel’s separation agreement based on Chembio’s purported failure
to pay Mr. Sperzel consulting fees to which he claims to be entitled for consulting services allegedly performed following his separation. Count XIII of the
complaint alleges a claim for breach of an implied covenant of good faith and fair dealing under Nevada common law based on the allegation that Chembio
prevented Mr. Sperzel from obtaining the benefits of the stock option agreements and separation agreement. Mr. Sperzel alleges that he suffered damages in
excess of $3 million as a result of the purported breach of the covenant of good faith and fair dealing. Count XIV of the complaint purports to assert a claim
for quantum meruit, alleging that “it is reasonable for Sperzel to expect payment in exchange for ... services” he assertedly provided to us and, based on
allegations that upon his separation Mr. Sperzel was not informed as to the pending expiration of the stock options he later sought to exercise, that Chembio
has  been  unjustly  enriched.  Finally,  Count  XV  of  the  complaint  seeks  a  declaratory  judgment  that  Mr.  Sperzel  is  relieved  from  performance  under  his
separation agreement due to asserted material breaches of the agreement based on the allegations summarized above. The complaint seeks compensatory
damages  in  an  unspecified  amount,  a  declaration,  as  described  above,  and  an  award  of  Mr.  Sperzel’s  costs  and  expenses  in  the  litigation,  including
reasonable attorneys’ fees, expert costs and disbursements. The complaint requests a trial by jury. In recently served initial disclosures, Mr. Sperzel claims
entitlement to recover damages in a total amount not less than $10 million, together with prejudgment interest at the rate of 9% per annum.

On May 20, 2021, Chembio filed its answer and affirmative defenses denying the material allegations of Mr. Sperzel’s complaint. Chembio and Mr. Sperzel
are  presently  engaged  in  discovery.  Under  the  present  case  schedule,  all  discovery  is  expected  to  be  completed  by  April  28,  2022.  At  this  stage  of  the
litigation, the Company is not able to predict the probability of a favorable or unfavorable outcome.

Other

From  time  to  time  the  Company  may  become  involved  in  legal  proceedings  or  may  be  subject  to  claims  arising  in  the  ordinary  course of its business.
Although the results of litigation and claims cannot be predicted with certainty, the Company currently believes that the final outcome of these ordinary
course  matters  will  not  have  a  material  adverse  effect  on  its  business,  operating  results,  financial  condition  or  cash  flows.  Regardless  of  the  outcome,
litigation can have an adverse impact on the Company because of defense and settlement costs, diversion of management resources, and other factors.

NOTE 13 — LONG-TERM DEBT:

On September 3, 2019, the Company entered into a Credit Agreement and Guaranty (the “Credit Agreement”) with Perceptive Credit Holdings II, LP (the
“Lender”). The Credit Agreement provides for a $20,000,000 senior secured term loan credit facility, which was drawn in full on September 4, 2019. Under
the terms of the Credit Agreement, the Company may use the proceeds (i) for general working capital purposes and other permitted corporate purposes, (ii)
to refinance certain of the Company’s existing indebtedness and (iii) to pay fees, costs and expenses incurred in connection with the Credit Agreement,
including the Lender’s closing cost amount of $550,000, which was netted from the proceeds, and a financing fee of $600,000 (3.0% of gross proceeds)
payable to Craig-Hallum Capital Group LLC, the Company’s financial advisor for the financing.

Principal outstanding under the Credit Agreement bears interest at a rate per annum equal to the sum of (a) the greater of the one-month London Interbank
Offered Rate and 2.5% plus (b) 8.75%. At any time at which an event of default has occurred and is continuing, the interest rate will increase by 4.0%.
Accrued interest is payable on a monthly basis. On December 31, 2021 the interest rate was 11.25%.

No principal repayments are due under the Credit Agreement prior to September 30, 2022, unless the Company elects to prepay principal or principal is
accelerated pursuant to an event of default identified in the Credit Agreement. Principal installments in the amount of $300,000 are payable on the last day
of  each  of  the  eleven  months  from  September  2022  through  July  2023,  and  all  remaining  principal  is  payable  at  maturity  on  September  3,  2023.  The
Company may prepay outstanding principal from time to time, subject to payment of a premium on the prepaid principal amount equal to 10% through
September 3, 2020, 8% from September 4, 2020 through September 3, 2021, and 4% from September 4, 2021 through September 3, 2022. No premium
will be due with respect to any prepayment made on or after September 4, 2022.

Chembio’s obligations under the Credit Agreement are secured by a first priority, perfected lien on substantially all of its property and assets, including its
equity interests in subsidiaries.

As of December 31, 2021, the loan balance, net of unamortized discounts and debt issuance costs, was $18.8 million, and Chembio was in compliance with
its loan covenants.

NOTE 14 — IMPAIRMENT, RESTRUCTURING, SEVERANCE AND RELATED COSTS:

The Company recorded an impairment loss of $1.3 million during the second quarter of 2021, as the result of its write-off of the intangible assets, net,
leasehold  improvements,  net  and  right-of-use  assets  for  leases,  net  associated  with  its  Malaysian  operations  that  underwent  a  retrenchment  during  the
second quarter of 2020. During the second quarter of 2021, the Company was informed that the World Health Organization had prioritized its review of
prequalification of the manufacture of the Company’s HIV 1/2 STAT-PAK Assay on its U.S. automated manufacturing processes, which would reduce the
Company’s reliance on manual labor that otherwise could have been performed at the Malaysian facilities had the Company re-started operations there.
During  July  2021,  the  World  Health  Organization  approved  the  change  notification.  The  products  produced  on  the  Company’s  automated  and  manual
production lines at any time depend on, among other things, the timing of customer orders and the mix of products being produced.

In light of the uncertainty of the timing and any receipt of those regulatory approvals, the timing of progress on and results of clinical trial programs, and
the timing and any receipt of product orders from the commercialization of the COVID-19 Diagnostic Test Systems and other diagnostic test systems both
within and outside the United States, during the second quarter of 2021, the Company engaged the services of an independent financial advisory firm (the
“Financial  Advisor”).  The  Financial  Advisor  worked  with  management  to  develop  a  forecast  model  to  assess  the  amount  and  timing  of  the  Company’s
liquidity needs, assuming various business cases, and together with legal counsel advised the Company regarding alternative approaches to enhancing its
liquidity  position,  participating  in  discussions  with  the  Lender,  and  related  matters.  During  the  year  ended  December  31,  2021  and  2020,  the  Company
incurred $1.1 and $0.4 million, respectively, related to these restructuring matters.

F-32

Table of Contents

In order to address challenging economic conditions and implement its business strategy, in the first quarter of 2021 the Company continued to execute a
program  to  reduce  operating  expenses  and  better  align  its  costs  with  revenues,  including  by  eliminating  positions  that  were  no  longer  aligned  with  its
strategy, and recognized severance charges of $0.1 million.

On February 17, 2022, Chembio Diagnostics GmbH, our German subsidiary formed under the laws of the Federal Republic of Germany, has filed a petition
for insolvency in the  Charlottenburg  District  Court    (“Amtsgericht  Charlottenburg“)  in  Berlin,  Germany  in  compliance  with  German  insolvency  law.  A
provisional insolvency administrator (“Administrator”) has been appointed to manage cash disbursements and general affairs of the business. We expect to
provide certain support and liquidity for the subsidiary to continue operations until such time a viable business strategy has been determined and agreed to
with the Administrator.
