Item 1. Business

Please refer to the Glossary at the end of this Business section for definitions or descriptions of scientific, diagnostic, healthcare, regulatory, and OpGen-
specific terms used in this Annual Report.

Overview

OpGen, Inc. (the “Company”) is a precision medicine company harnessing the power of molecular diagnostics and informatics to help combat infectious
disease. Along with our subsidiaries, Curetis GmbH and Ares Genetics GmbH, we are developing and commercializing molecular microbiology solutions
helping  to  guide  clinicians  with  more  rapid  and  actionable  information  about  life  threatening  infections  to  improve  patient  outcomes  and  decrease  the
spread of infections caused by multidrug-resistant microorganisms, or MDROs. Our current product portfolio includes Unyvero, Acuitas AMR Gene Panel,
and the ARES Technology Platform including ARESdb, using NGS technology and AI-powered bioinformatics solutions for antibiotic response prediction,
as well as the Curetis CE-IVD-marked PCR-based SARS-CoV-2 test kit. The Company exited its FISH business in early 2021, and the Company's license
agreement with Life Technologies, a subsidiary of Thermo Fisher, was terminated as of June 30, 2021.

On April 1, 2020, the Company completed a business combination transaction whereby the Company acquired Curetis GmbH, a private limited liability
company  organized  under  the  laws  of  the  Federal  Republic  of  Germany  (“Curetis  GmbH”).  Curetis  is  an  early  commercial-stage  molecular  diagnostics
(MDx) company focused on rapid infectious disease testing for hospitalized patients with the aim to improve the treatment of hospitalized, critically ill
patients with suspected microbial infection and has developed the innovative Unyvero molecular diagnostic solution for comprehensive infectious disease
testing. The business combination transaction was designed principally to leverage each company’s existing research and development and relationships
with hospitals and clinical laboratories to accelerate the sales of both companies’ products and services.

The focus of OpGen is on its combined broad portfolio of products, which includes high impact rapid diagnostics and bioinformatics to interpret AMR
genetic data. The Company currently expects to focus on the following products for lower respiratory infection, urinary tract infection and invasive joint
infection:

·

·

·

·

The  Unyvero  Lower  Respiratory  Tract,  or  LRT,  test  (e.g.  for  bacterial  pneumonias)  is  the  first  U.S.  Food  and  Drug  Administration,  or  FDA,
cleared test that can be used for the detection of more than 90% of common causative agents of hospitalized pneumonia. According to the National
Center for Health Statistics (2018), pneumonia is a leading cause of admissions to the hospital and is associated with substantial morbidity and
mortality. The Unyvero LRT automated test detects 19 pathogens within less than five hours, with approximately two minutes of hands-on time
and provides clinicians with a comprehensive overview of 10 genetic antibiotic resistance markers. We have commercialized the Unyvero LRT
BAL test for testing bronchoalveolar lavage, or BAL, specimens from patients with lower respiratory tract infections following FDA clearance
received by Curetis in December 2019. The Unyvero LRT BAL automated test simultaneously detects 20 pathogens and 10 antibiotic resistance
markers,  and  it  is  the  first  and  only  FDA-cleared  panel  that  also  includes  Pneumocystis  jirovecii,  a  key  fungal  pathogen  often  found  in
immunocompromised  patients  (such  as  AIDS  and  transplant  patients)  that  can  be  difficult  to  diagnose,  as  the  20th  pathogen  on  the  panel.  We
believe the Unyvero LRT and LRT BAL tests have the ability to help address a significant, previously unmet medical need that causes over $10
billion in annual costs for the U.S. healthcare system, according to the Centers for Disease Control, or CDC.

Following registration of the Unyvero instrument system as an IVD for the Chinese market in early 2021, we are supporting our strategic partner
Beijing  Clear  Biotech  (BCB)  in  pursuing  execution  of  a  supplemental  clinical  trial  with  the  Unyvero  HPN  test.  As  requested  by  the  Chinese
regulatory authority NMPA, this study is geared towards generating additional data in China that will complement a larger data set with data from
abroad compiled from other clinical and analytical studies performed in the past.

The Unyvero Urinary Tract Infection, or UTI, test, which is CE-IVD marked in Europe, is currently being made available to laboratories in the
United States as a research use only or RUO kit. The test detects a broad range of pathogens as well as antimicrobial resistance markers directly
from native urine specimens. We initiated a prospective multi-center clinical trial for the Unyvero UTI in the United States in the third quarter of
2021.

The Unyvero Invasive Joint Infection, or IJI, test, which is a variant being developed for the U.S. market, has also been selected for analytical and
clinical performance evaluation including clinical trials towards a future U.S. FDA submission. Microbial diagnosis of IJI is difficult because of
challenges  in  sample  collection,  usually  at  surgery,  and  patients  being  on  prior  antibiotic  therapy  which  minimizes  the  chances  of  recovering
viable  bacteria.  We  believe  that  Unyvero  IJI  could  be  useful  in  identifying  pathogens  as  well  as  their  AMR  markers  to  help  guide  optimal
antibiotic treatment for these patients.

·

On September 30, 2021, we received clearance from the FDA for our Acuitas AMR Gene Panel for bacterial isolates. The Acuitas AMR Gene
Panel  detects  28  genetic  antimicrobial  resistance,  or  AMR,  markers  in  isolated  bacterial  colonies  from  26  different  pathogens.  We  believe  the
panel  provides  clinicians  with  a  valuable  diagnostic  tool  that  informs  about  potential  antimicrobial  resistance  patterns  early  and  supports
appropriate antibiotic treatment decisions in this indication. We expect to commercialize the Acuitas AMR Gene Panel for isolates more broadly to
customers in the United States.

· We are also developing novel bioinformatics tools and solutions to accompany or augment our current and potential future IVD products and may
seek regulatory clearance for such bioinformatics tools and solutions to the extent they would be required either as part of our portfolio of IVD
products or even as a standalone bioinformatics product.

OpGen has extensive offerings of additional IVD tests including CE-IVD-marked Unyvero tests for hospitalized pneumonia patients, implant and tissue
infections,  intra-abdominal  infections,  complicated  urinary  tract  infections,  and  blood  stream  infections.  Our  portfolio  furthermore  includes  a  CE-IVD-
marked PCR based rapid test kit for SARS-CoV-2 detection in combination with our PCR compatible universal lysis buffer (PULB).

OpGen’s combined AMR bioinformatics offerings, when and if such products are cleared for marketing, will offer important new tools to clinicians treating
patients with AMR infections. OpGen’s subsidiary Ares Genetics’ ARESdb is a comprehensive database of genetic and phenotypic information. ARESdb
was originally designed based on the Siemens microbiology strain collection covering resistant pathogens and its development has significantly expanded,
as a result of transferring data from the discontinued Acuitas Lighthouse into ARESdb to now cover > 78,000 bacterial isolates that have been sequenced
using NGS technology and tested for susceptibility with applicable antibiotics from a range of over 100 antimicrobial drugs. In the fourth quarter of 2021,
Ares  Genetics  entered  into  a  strategic  database  access  deal  with  one  of  the  world’s  leading  microbiology  and  IVD  corporations  for  their  non-exclusive
access to approximately 1.1% of Ares Genetics’ total database asset at the time of signing. Ares Genetics continues to explore various discussions with
several  interested  parties  in  potential  future  collaboration  or  licensing  opportunities.  Additional  partnerships  with  a  U.S.  CLIA  lab,  a  contract  research
organization  (“CRO”)  and  a  major  University  Medical  Center  have  been  initiated  and  are  ongoing  and  the  collaboration  master  service  agreement  with
Sandoz has recently been extended until January 2025.

In addition to potential future licensing and partnering, Ares Genetics intends to independently utilize the proprietary biomarker content in this database, as
well as to build an independent business in NGS and AI based offerings for AMR research and diagnostics in collaboration with its current and potential
future  partners  in  the  life  science,  pharmaceutical  and  diagnostics  industries.  Ares  Genetics  signed  up  Siemens  Technology  Accelerator  and  AGES
(Austrian Agency for Health and Food Safety), as well as several other national institutions from various European countries as new customers.

OpGen’s subsidiary Curetis’ Unyvero A50 tests for up to 130 diagnostic targets (pathogens and resistance genes) in under five hours with approximately
two minutes of hands-on time. The system was first CE-IVD-marked in 2012 and was FDA cleared in 2018 along with the LRT test through a De Novo
request. The  Unyvero  A30  RQ  is  a  new  device  designed  to  address  the  low-to  mid-plex  testing  market  for  5-30  DNA  targets  and  to  provide  results  in
approximately  30  to  90  minutes  with  2-5  minutes  of  hands-on  time.  The  Unyvero  A30  RQ has a small benchtop footprint and has an attractive cost of
goods profile. Curetis has been following a partnering strategy for the Unyvero A30 RQ and, following the successful completion of a key development
milestone,  Curetis  has  completed  final  verification  and  validation  testing  of  the  A30  instruments  and  is  actively  engaged  in  several  ongoing  partnering
discussions and due diligence under respective material transfer agreements.

The Company has extensive partner and distribution relationships to help accelerate the establishment of a global infectious disease diagnostic testing and
informatics business. The Company’s partners include A. Menarini Diagnostics S.r.l. for pan-European distribution to currently 12 countries and Beijing
Clear Biotech Co. Ltd. for Unyvero A50 product distribution in China. We have a network of distributors covering countries in Europe, the Middle East
and  Africa,  Asia  Pacific  and  Latin  America.  With  the  discontinuation  of  our  FISH  products  business  in  Europe,  we  have  reduced  our  network  of
distributors to only those distributors actively commercializing our Unyvero line of products or CE-IVD-marked SARS-CoV-2 test kits.

OpGen will continue to develop and seek FDA and other regulatory clearances or approvals, as applicable, for our Unyvero UTI and IJI products. OpGen
will continue to offer the FDA-cleared Unyvero LRT and LRT BAL Panels, and FDA-cleared Acuitas AMR Gene Panel tests, as well as the Unyvero UTI
Panel as a RUO product to hospitals, public health departments, clinical laboratories, pharmaceutical companies and CROs. OpGen’s subsidiary, Curetis,
continues its preparations for achieving compliance with the upcoming European Union’s In-Vitro-Diagnostic Device Regulation (IVDR), which officially
will go into effect in May 2022. Given the lack of designated Notified Bodies at this time, and with the recently approved EU commission proposal to
provide for generous multi-year grace periods for IVD products with current In-Vitro-Diagnostic Device Directive (IVDD) CE marking, it is now possible
for  Curetis  to  continue  its  portfolio  of  existing  CE-IVD  marked  products  until  at  least  May  2025  and  May  2026,  respectively,  as  long  as  no  material
changes  are  being  made  to  any  of  its  products.  Following  May  2022,  however,  any  new  or  changed  CE  marked  products  will  be  required  to  be  IVDR
compliant from the outset.

OpGen’s Products and Products in Development

Through its subsidiary Curetis, OpGen maintains a comprehensive portfolio of molecular diagnostics for rapid infectious disease and AMR testing. At the
core  of  the  portfolio  is  the  Unyvero  platform  and  product  family,  which  is  developed,  manufactured  and  commercialized  via  the  wholly  owned  Curetis
GmbH subsidiary. On the bioinformatics side, OpGen has combined data from its now discontinued Acuitas Lighthouse with the Ares Genetics (Ares) data
into the ARESdb. Ares develops and commercializes its NGS as well as bioinformatics based, AI-powered prediction models and solutions to partners and
customers in the pharma, biotech and diagnostics industries as well as to public research institutions.

OpGen  is  a  molecular  diagnostics  company  that  focuses  on  the  development  and  commercialization  of  reliable,  fast  and  cost-effective  products  for
diagnosing  severe  infectious  diseases  in  hospitalized  patients,  an  indication  with  a  high  unmet  medical  need  and  significant  prevalence  in  developed
countries. Our unique Unyvero Platform currently comprises the Unyvero System with the Unyvero A50 Analyzer at its core, proprietary software, and
single use Application Cartridges. These Application Cartridges contain molecular tests addressing specific severe infectious diseases and detect a broad
range of pathogens relevant in a given indication and associated toxin genes and genetic antimicrobial resistance markers.

The Unyvero Platform has been CE-IVD-marked since 2012 and is commercialized in Europe and certain other markets that accept CE-IVD-marking or
where it has successfully passed the registration process (i.e. Colombia, Kuwait, Belarus, Singapore), and has been rolled out commercially in the United
States following De Novo clearance of the Unyvero System and the LRT Application Cartridge by the FDA in April 2018 and the 510(k) clearance of the
LRT Application for BAL samples in December 2019.

Today, the diagnosis of infectious diseases in the hospital setting is still largely carried out through traditional culture-based microbiology methods. This
process  is  labor-intensive  and  time-consuming,  typically  delivering  results  only  after  24  to  72  hours  or,  in  some  cases,  weeks.  As  a  result,  informed
antibiotic therapy decisions may be delayed, which can lead to poor patient outcomes, including higher mortality rates for indications such as pneumonia
and sepsis, longer hospital stays, increased hospital costs and overall spread of antibiotic resistance, a significant and increasing problem throughout the
world. All of these factors pose clinical and economic challenges to hospitals and a significant threat to public health globally.

OpGen aims to improve on this standard-of-care by offering comprehensive test information in a timely manner that allows for early, efficacious treatment,
which OpGen believes results in improved clinical and health economic outcomes. The Company’s Unyvero Platform delivers results within four to five
hours and can cover over 100 diagnostic targets. The broad Unyvero test panels also allow the identification of microorganisms that are difficult to culture
and hence missed in culture-based test methods, as well as rare but critical pathogens not routinely tested for by standard methods, a conclusion confirmed
by a number of clinical studies. The FDA clinical trial for the LRT Application Cartridge concluded that the Unyvero System identified 32 positive atypical
pathogen results in 1,653 prospectively tested specimens, as opposed to only four confirmed positive atypical pathogen results identified in 116 specimens
from this cohort using traditional culture-based diagnostic methods. The Company believes this allows clinicians to make early adjustments to the specific
treatment of the patient, saving significant time and cost, in particular by reducing the duration of the patient’s hospital stay.

The  Unyvero  Platform  is  intended  to  complement  rather  than  replace  traditional  microbiology-based  diagnostics  testing.  OpGen  believes,  however,  that
timely  diagnosis  of  the  underlying  pathogens  and  their  resistances  could  greatly  improve  outcomes  for  patients  and  is  likely  to  provide  net  savings  to
hospitals.

The Unyvero Platform is marketed through a combination of direct sales in the United States and a growing network of distribution partners in Europe,
Middle  East,  the  ASEAN  Region,  Asia  and  Latin  America.  As  of  December  31,  2021,  the  distribution  network  comprises  14  distributors  covering  31
countries  in  those  regions  with  regulatory  clearance  for  the  Unyvero  System  and  the  Unyvero  Application  Cartridges  in  some  of  these  countries  still
pending.

7 

 
 
 
 
 
There are currently seven commercially available Application Cartridges, consisting of:

·

·

·

·

·

·

·

the HPN Application Cartridge, which addresses severe forms of pneumonia and is CE-IVD-marked in Europe;

the ITI Application Cartridge, which addresses severe cases of implant and tissue infections and is CE-IVD-marked in Europe;

the BCU Application Cartridge, which addresses severe blood stream infections and is CE-IVD-marked in Europe;

the IAI Application Cartridge, which addresses intra-abdominal infections and is CE-IVD-marked in Europe;

The  UTI  Application  Cartridge,  which  addresses  severe  urinary  tract  infections  and  is  CE-IVD-marked  in  Europe.  The  Company  has  begun
analytical and clinical performance evaluations, including clinical trials initiated in the third quarter of 2021, required for a subsequent U.S. FDA
submission;

the  LRT  Application  Cartridge,  which  is  technically  similar  to  the  HPN  Application  Cartridge  and  also  addresses  severe  forms  of  pneumonia,
which was cleared by the FDA in April 2018 for use with tracheal aspirates and is now being marketed in the United States; and

the LRT BAL Application Cartridge which was cleared on December 20, 2019 by the FDA for use with BAL specimens and has been launched in
the Unites States in the first quarter of 2020.

In addition to the current Unyvero System, the Company through its subsidiary Curetis also develops its Unyvero A30 RQ Analyzer module designed to
offer a rapid time-to-result (potentially as fast as 30 to 90 minutes), qualitative and, where needed, quantitative real-time PCR testing in a cartridge format
that can provide up to 11 parallel multiplex (i.e. simultaneously running multiple assays in one reaction) PCR reactions from one sample, with up to three
assays per reaction (for a total of up to 33 assays per cartridge). The Unyvero A30 RQ Analyzer is expected to be operated on a stand-alone basis or fully
integrated into the Unyvero System suite of products with respect to system architecture, design, software and handling, thereby expanding the Unyvero
Platform to include low- and mid-plex capabilities. We expect that the costs of the Unyvero A30 RQ Analyzer and cartridges will be lower than those for
the  current  Unyvero  System  and  A50  Application  Cartridges,  potentially  opening  up  commercial  opportunities  in  the  medium  multiplexing  infectious
disease  testing  market  segment.  Initially  developed  as  an  expansion  of  the  Unyvero  platform,  complementing  the  Unyvero  A50  high-plex  Application
Cartridges with low- to mid-plex Unyvero A30 RQ Application Cartridges for infectious diseases, OpGen adjusted its strategy and now also seeks partners
in the global IVD industry that may want to license the Unyvero A30 RQ for commercialization of their own assays on this platform, potentially even as
legal manufacturer under their own branding.

The Unyvero Platform

Curetis  launched  its  CE-IVD-marked  Unyvero  Platform  with  a  first  disposable  Application  Cartridge  for  pneumonia  in  2012.  The  FDA  cleared  the
Unyvero  System  and  LRT  Application  Cartridge  in  April  2018  and  the  LRT  BAL  Application  Cartridge  in  December  2019.  The  Chinese  authorities
National Medical Products Administration (“NMPA”) cleared the Unyvero System in early 2021.

The Unyvero Platform is a highly automated sample-to-answer molecular diagnostics platform, based on multiplexed end-point PCR with an array-based
detection  process.  It  integrates  fully  automated  sample  preparation,  analysis  and  identification  of  disease  relevant  pathogens  and  antibiotic  resistance
markers to provide timely high-quality information to its end-users. The scalable system is designed to be either placed in laboratory settings or directly in
hospital wards or intensive care units. Time-to-result is four to five hours for the different Application Cartridges commercially available today, including
30 minutes of automated sample preparation (lysis) and total hands-on time of no more than five minutes. The Unyvero Platform’s intuitive workflow with
only minimal hands-on time enables untrained hospital staff to perform molecular tests at the point of need, such as ICUs.

Unyvero Platform, System Components and Workflow

The Unyvero System consists of three devices, the Unyvero L4 Lysator, the Unyvero C8 Cockpit and the Unyvero A50 Analyzer. The Unyvero L4 Lysator
is used for sample pre-processing and pathogen lysis. The Unyvero C8 Cockpit is the control panel for the Unyvero L4 Lysator and Unyvero A50 Analyzer
and  displays  the  results  of  patient  sample  analysis.  The  Unyvero  A50  Analyzer  integrates  mechanical,  electronic,  pneumatic  and  optical  elements  and
enables  a  fully  automatic  random-access  processing  of  the  Application  Cartridges.  The  Application  Cartridges  are  single-use,  disposable  and  disease
specific. The Unyvero System, together with proprietary software and the Application Cartridges, comprise the Unyvero Platform.

The Unyvero L4 Lysator

Figure 1: Unyvero Platform

The Unyvero L4 Lysator instrument is used for sample pre-processing and pathogen lysis. It performs proprietary software-controlled lysis of up to four
samples,  simultaneously  within  30  minutes,  combining  mechanical,  thermal,  enzymatic  and  chemical  lysis  steps  and  allows  the  use  of  a  wide  range  of
native  sample  types  due  to  a  proprietary  sample  processing  method  (in  respect  of  which  several  patents  have  been  granted  or  are  currently  pending).
Biofilm-forming pathogens can be detected by the Unyvero Platform. In addition, the Unyvero Platform is CE-IVD-marked for a broad variety of native
patient sample types including sputum, (mini) BAL, tracheal aspirates, aspirates and exudates, catheter tips, pus, sonication fluid, synovial fluid, swabs and
tissue.  The  lysis  of  further  sample  types  such  as  blood,  urine,  stool  and  formalin-fixed  paraffin  embedded  tissues  is  also  possible  with  the  proprietary
Unyvero  lysis  method.  Up  to  two  Unyvero  L4  Lysators  can  be  attached  to  a  single  Unyvero  C8  Cockpit  to  allow  processing  of  up  to  eight  samples
simultaneously within 30 minutes.

The Unyvero C8 Cockpit

The Unyvero C8 Cockpit device is the control panel for the Unyvero L4 Lysator and Unyvero A50 Analyzer. It has a touchscreen and built-in bar code
reader and runs on proprietary in-house developed Unyvero software. Step-by-step instructions guide the user from preparing a test to executing the fully
automated process in the Unyvero A50 Analyzer in just a few minutes. The results display, storage of results and data storage, as well as information about
the performed tests including the Application Cartridges’ shelf-life and lot numbers, are generated automatically. Data can be exported as PDF files via a
USB key or to a connected printer. It also features built-in interfaces for connectivity to hospital and laboratory information systems.

The Unyvero A50 Analyzer

The Unyvero A50 Analyzer instrument consists of mechanical, electronic, pneumatic and optical elements and enables a fully-automatic random-access
processing of the A50 Application Cartridges. Once a run is started, the Unyvero A50 Analyzer automatically executes and controls all sample processing
and analysis steps (including DNA extraction, DNA purification, PCR set-up, highly multiplexed end-point PCR amplification and a hybridization array-
based fluorescence detection) inside the Application Cartridge. For safety and equipment longevity, and to avoid issues of calibration or waste-removal, the
Unyvero  A50  Analyzer  contains  neither  reagents  nor  waste.  All  fluids  are  handled  within  the  sealed  Application  Cartridge.  Up  to  four  Unyvero  A50
Analyzers can be attached to a single Unyvero C8 Cockpit and each Unyvero A50 Analyzer includes the two available slots that provide full random access
per Unyvero A50 Analyzer, allowing the processing of up to eight patient samples simultaneously within four to five hours. In the future, OpGen believes a
further expansion to up to eight Unyvero A50 Analyzers will also be possible.

Workflow

The  Unyvero  Platform  is  a  modular,  flexible  easy-to-use  platform,  which  substantially  reduces  turnaround  time  from  up  to  24  hours  or  even  weeks  for
traditional microbiology culture-based tests to approximately four to five hours. This allows physicians to adjust treatment at a much earlier stage than with
the traditional microbiology culture-based test, which is the current clinical standard of care. OpGen believes that the reduced hands-on time of no more
than five minutes and the intuitive workflow make the system operable by non-specialty trained laboratory personnel and reduce the risks of errors.

The HPN and LRT Application Cartridges

The  HPN  Application  Cartridge  was  commercially  launched  in  April  2015  and  is  the  second-generation  version  of  the  P50  Application  Cartridge,  the
Pneumonia  Application  Cartridge  originally  launched  in  2012.  It  is  a  CE-IVD-marked  Application  Cartridge  for  the  fully  automated  performance  of
currently 21 PCR assays for microorganisms and 19 PCR assays for antibiotic resistance markers combined in a total of eight multiplex PCR reactions on
native  respiratory  samples,  such  as  sputum,  tracheal  aspirates  and  BAL  fluids  with  no  pre-culturing  required.  This  Application  Cartridge  combines  the
necessary detection of bacteria, fungus and resistance markers into a single test to aid diagnosing pneumonia. With the HPN Application Cartridge, the
Company aims to detect the vast majority of pneumonia-causing pathogens and antibiotic resistance markers in hospitalized patients.

The HPN Application Cartridge of microorganisms and resistance gene markers was designed based on feedback of clinical experts and international and
national  guidelines.  It  aims  to  detect  at  least  90%  of  healthcare-associated  pneumonia-causing  pathogens  and  clinically  relevant  resistances  against
antimicrobials. The Application Cartridge is primarily designed to capture patients at risks for:

· microorganisms causing severe, and complicated to treat, forms of pneumonia, e.g. Pseudomonas aeruginosa;

· microorganisms carrying antibiotic resistance and where patients may need isolation (MRSA, Klebsiella);

·

·

infections with multidrug-resistant bacteria that might not be targeted by empiric treatment schemes; and

rare and difficult to detect pathogens like Legionella sp.

The Application Cartridge composition takes pathogen incidences into account. It includes those microorganisms showing an incidence of above 1%. The
Application Cartridge is completed by adding pathogens with lower incidence but a high clinical need, such as Legionella sp.

The  HPN  Application  Cartridge  covers  19  antibiotic  resistance  markers,  including:  (i)  ß-Lactam  resistance,  including  ESBL;  (ii)  kpc  resistance;  (iii)
macrolide resistance; (iv) quinolone resistance; and (v) multi-drug resistance.

The  LRT  Application  Cartridge  was  launched  in  the  United  States  in  April  2018.  It  is  an  FDA-cleared  Application  Cartridge  for  the  fully  automated
detection  of  46  targets,  covering  36  microorganisms  and  10  antibiotic  resistance  markers,  for  lower  respiratory  tract  infections  with  a  total  of  29  PCR
assays combined in eight multiplexed PCR reactions. Although similar in most respects to the HPN Application Cartridge, the LRT differs from the HPN in
its pathogen reporting due to FDA reporting requirements. In accordance with a De Novo request that was granted by the FDA in April 2018, the initial
label claim covers the use of LRT with tracheal aspirate samples only and has cleared 19 pathogen assays as well as 10 antibiotic resistance marker assays.

The LRT BAL Application Cartridge that was 510(k)-cleared by the U.S. FDA in December 2019 and launched in the United States in January 2020, is a
version of the LRT Application Cartridge that is optimized for use with commonly obtained BAL specimens. The Unyvero LRT BAL application is the
first  and  only  U.S.  FDA-cleared  molecular  diagnostic  panel  that  detects  Pneumocystis  jirovecii  in  addition  to  a  broad  spectrum  of  clinically  relevant
bacterial pathogens and antibiotic resistance markers associated with pneumonia.

The ITI Application Cartridge

The ITI Application Cartridge was launched in May 2016 and is the second-generation version of the ITI Application Cartridge originally launched in the
second quarter of 2014. Improvements were made to the panel and analytical performance as well as clinical sensitivity and specificity. It is a CE-IVD-
marked Application Cartridge for the fully automated detection of currently 102 targets, covering 85 microorganisms and 17 antibiotic resistance markers
for  eight  different  clinical  indications  within  the  areas  of  prosthetic  joint  infections,  surgical  site  infections,  diabetic  foot  ulcers,  catheter-associated
infections,  deep  skin  and  tissue  infections,  cardiology-related  infections,  burn  wounds  and  other  implant  infections.  CE  performance  evaluation  has
demonstrated sensitivity of 86.9% at specificity of 99.2%. A diverse range of sample types such as aspirates and exudates, pus, sonication fluid, swabs,
synovial fluid and tissue can be used on this Application Cartridge. Moreover, biofilm-forming pathogens can be identified by the Unyvero Platform. The
ITI Application Cartridge was jointly developed and co-funded with a worldwide market leader in orthopedic bone cement, which offers comprehensive
infection management solutions. The Company pays a customer referral commission but has retained full control on product commercialization.

The BCU Application Cartridge

The BCU Application Cartridge was launched in Europe in April 2016. It is a CE-IVD-marked and Singapore HSA-cleared Application Cartridge for the
fully automated detection of 103 targets, covering 87 microorganisms and 16 antibiotic resistance markers relevant in the area of blood stream infections.
The CE-IVD performance evaluation has demonstrated a weighted average sensitivity for all pathogens of 96.2%, and a weighted average specificity of
99.4%.  Unlike  other  Unyvero  Application  Cartridges,  BCU  uses  samples  from  positive  blood  cultures  rather  than  native  patient  samples.  Such  blood
cultures are started in cases of suspected blood stream infections.

11 

 
 
 
 
 
 
The IAI Application Cartridge

The IAI Application Cartridge was launched in April 2017. It is a CE-IVD-marked Application Cartridge for the fully automated detection of 130 targets,
covering  105  pathogens,  three  toxins  and  22  resistance  markers  for  several  different  clinical  indications  within  the  areas  of  severe  intra-abdominal
infections such as symptoms of peritonitis, appendicitis, acute abdomen, acute pancreatitis, and megacolon. Overall weighted average sensitivity for the
pathogens specifically targeted by the test panel was 93.8% at an overall weighted average specificity of 99.7% following discrepant result resolution.

The UTI Application Cartridge

The UTI Application Cartridge was launched in April 2018. It is a CE-IVD-marked Application Cartridge for the fully automated detection of up to 103
diagnostic targets, covering 88 microorganisms and 15 genetic resistance markers for the areas of severe urinary tract infections in patients with anatomical,
structural  and  functional  alterations,  renal  impairments,  impaired  immune  status,  catheter-associated  UTI,  patients  failing  to  respond  to  therapy  and
suffering from severe manifestations, urosepsis. OpGen estimates that the addressable market for the UTI Application Cartridge is 1.6 million cases eligible
for  testing  per  year  in  the  EU  and  the  United  States.  The  UTI  Application  Cartridge  is  also  available  as  RUO  in  the  USA  since  2020.  As  part  of  our
portfolio strategy update in the fourth quarter of 2020, we decided to proceed with the analytical and clinical performance evaluation including clinical
trials required for a subsequent U.S. FDA submission for this Application Cartridge and initiated clinical trials in the third quarter of 2021.

Curetis’ SARS-CoV-2 Kit

CE  IVD  marked  in  2020,  Curetis  has  developed  and  commercializes  a  PCR  based  rapid  test  kit  for  SARS-CoV-2  detection.  It  uses  real-time  reverse
transcription  polymerase  chain  reaction  (RT-PCR)  technology  for  qualitative  detection  of  the  SARS-CoV-2  virus  isolated  from  oropharyngeal  and
nasopharyngeal swab specimens from individuals suspected of COVID-19 by their healthcare provider or for screening of asymptomatic individuals. This
kit can be used with RNA isolated by performing standard RNA isolation processes, as well as with oropharyngeal or nasopharyngeal swabs collected in
PCR compatible viral transport medium treated with PCR-Compatible Universal Lysis Buffer (PULB) provided in the kit.

Ares Genetics’ NGS and Bioinformatics Services for Molecular Microbiology

OpGen’s  other  core  business  in  NGS  and  bioinformatics  based  solutions  for  molecular  microbiology  is  operated  by  its  wholly-owned  subsidiary  Ares
Genetics GmbH, or Ares Genetics, founded in 2017 and based in Vienna, Austria. Ares Genetics’ business is based on the proprietary ARES Technology
Platform and Ares Genetics’ proprietary genetic database on AMR, ARESdb. The ARES Technology Platform and ARESdb build and expand upon the
GEAR  assets  acquired  from  Siemens  Technology  Accelerator  GmbH  in  2016.  On  the  bioinformatics  side,  OpGen  has  combined  data  from  its  now
discontinued Acuitas Lighthouse with the Ares Genetics (Ares) data into the ARESdb. Ares Genetics believes ARESdb is a unique comprehensive database
on  the  genetics  of  antibiotic  resistance.  Ares  Genetics  also  pursues  an  active  out-licensing  and  collaboration  strategy  with  suitable  partners  in  the  life
science,  pharmaceutical,  and  diagnostic  industry  to  jointly  develop  solutions  for  microbiology  relying  on  the  database  and/or  the  Ares  Technology
Platform. Ares Genetics entered into its first partnering and strategic collaborations with QIAGEN, Sandoz, and recently entered into a strategic data access
deal with one of the world’s leading microbiology and IVD corporations which obtained non-exclusive access to approximately 1.1% of Ares Genetics’
then-current datasets.

In addition to its out-licensing strategy, Ares Genetics offers next-generation molecular AMR testing services out of its NGS service lab opened in mid-
2019 in Vienna, Austria, with initial focus on infection control, AMR epidemiology and surveillance, clinical research and pharmaceutical anti-infectives
research and development.

Ares Genetics has also developed its ARESupa Universal Pathogenome Assay, which is based on the ARES Technology Platform and ARESdb. ARESupa
is intended to cover nearly any pathogen in a broad array of sample types and to predict antimicrobial drug response to a wide variety of treatment options
using a single NGS laboratory workflow.

In August 2019, Ares Genetics opened a specialized service laboratory offering next-generation AMR testing services with an initial focus on infection
control,  AMR  epidemiology  and  surveillance,  clinical  research  and  pharmaceutical  anti-infectives  research  and  development. All  services  are  based  on
NGS and Ares Genetics’ proprietary, AI-powered antimicrobial resistance database ARESdb and the ARES Technology Platform for data interpretation.
Ares Genetics expects to also begin offering its services in the United States.

12 

 
 
In 2022, Ares Genetics launched AREScloud, a software as a service offering. The commercially available web application is intended for research use
only  and  aims  at  professionals  in  clinical  microbiology,  public  health,  and  microbial  R&D.  AREScloud  intends  to  automate  the  accurate  analysis  and
comprehensive interpretation of microbial genome data for surveillance and infection prevention and control applications. The web application leverages
the contents of the proprietary ARESdb to enable the AI-assisted antibiogram prediction (referred to as predictive AST) directly from bacterial genome
data.

OpGen’s Acuitas AMR Gene Panel

We  believe  more  rapid  genetic  identification  methods  will  reduce  morbidity  from  MDROs,  reduce  healthcare  costs  through  reduced  length  of  stay,  and
assist in the identification of targeted antibiotic therapy. Current conventional microbiology, largely unchanged in 50 years, requires one to two days for
growth and phenotypic analysis and often leads to the use of broad spectrum antibiotic therapy in the early stages of infection.

OpGen has developed the Acuitas AMR Gene Panel, which was 510(k)-cleared by the U.S. FDA on September 30, 2021 for testing bacterial isolates. This
test had been made available in the United States as RUO before and had been used in such capacity in connection with The New York State Infectious
Disease Digital Health Initiative for testing of bacterial isolates.

The Acuitas  AMR  Gene  Panel  is  FDA  cleared  to  detect  a  comprehensive  panel  of  28  genetic  antimicrobial  resistance  (AMR)  markers,  covering  select
drugs  in  9  classes  of  antibiotics,  in  isolated  bacterial  colonies  from  26  different  pathogens.  An  identified  bacterial  isolate  is  tested,  and  the  antibiotic
resistance gene markers associated with the selected bacterial species are reported as “Detected”, “Not Detected” or “NA/NR”.

Market Overview

Antibiotic Resistance – An Urgent Global Issue

Antimicrobial resistance (AMR) is one of the greatest global public health threats that has been recognized by many international bodies, including the
World Health Organization (WHO) and the U.S. Centers for Disease Control and Prevention (CDC). A recent publication in The Lancet (January 19, 2022)
confirms the rapid spread of AMR infections and highlights that an estimated 4.95 million deaths were associated with AMR in 2019, and between 2014
and  2019,  the  burden  of  fatalities  directly  attributable  to  bacterial  AMR  rose  from  700K  to  1.27M.  The  growing  threat  of  AMR  to  public  health  is
exacerbated by existing and newly developed antibiotics facing a wide range of drug resistance mechanisms in pathogens of concern. Recent Infectious
Diseases Society of America (IDSA) treatment guidance for multidrug-resistant Gram-negative bacterial infections (Clin Infect Dis 2021 Apr 8;72(7):e169-
e183) highlights how detection of AMR genes or a specific mechanism of resistance can help guide reporting practices for novel antimicrobial agents and
tailor  therapy  for  these  difficult  to  treat  infections.  Furthermore,  it  can  help  with  infection  prevention  and  control  initiatives  such  as  patient  isolation
procedures when multiple isolates with the same AMR profile are detected as an early indication of transmission within a facility or for surveillance of
serious or emerging AMR threats.

Antibiotic-resistant infections add considerable but often avoidable costs to the U.S. healthcare system. In most cases, these infections require prolonged
and/or costlier treatments, extended hospital stays, additional doctor visits and healthcare facilities use, and result in greater disability and death compared
with  infections  that  are  treatable  with  antibiotics.  Estimates  for  the  total  economic  cost  to  the  U.S.  economy  are  difficult  to  calculate  but  have  been
estimated to be as high as $20 billion in excess direct healthcare costs annually.

Over the last decade, multidrug-resistant Gram-negative bacteria, frequently referred to as Superbugs, have been implicated in severe healthcare-associated
infections (HAIs), and their occurrence has increased steadily. For example, Klebsiella pneumoniae, or K. pneumoniae, is responsible for roughly 15% of
Gram-negative infections in hospital intensive care units. Infections caused by KPC strains have few treatment options and are associated with a mortality
rate upwards of 50%.

Exacerbating  the  problems  associated  with  the  emergence  of  these  highly  resistant  KPC  strains  is  their  propensity  to  cause  outbreaks  in  healthcare
institutions.  These  pathogens  persist  both  in  the  flora  of  hospitalized  patients  and  in  the  hospital  environment,  and  they  have  the  capacity  to  silently
colonize  patients  or  hospital  personnel  by  establishing  residence  in  the  gastrointestinal  tract  without  causing  any  signs  of  infection.  Individuals  can  be
silently colonized or become asymptomatic carriers for long periods of time, with detection of these carriers often proving difficult. These silent carriers act
as reservoirs for continued transmission, which makes subsequent spread difficult to control and outbreaks difficult to stop. In addition, KPC strains can
survive for several hours on the hands of hospital personnel, which likely facilitates the spread of organisms from patient to patient. Effective control of
KPC  outbreaks  requires  a  detailed  understanding  of  how  transmission  occurs,  but  current  technologies  do  not  allow  healthcare  providers  to  routinely
perform these investigations on a timely basis.

13 

 
 
 
The lack of currently available treatment options and scarcity of new treatment options in development are compounding the emerging Superbug problem.
It  has  been  close  to  30  years  since  a  new  class  of  antibiotics  was  developed  and  successfully  introduced.  As  a  result,  we  believe  that  rapid,  accurate
identification  of  the  pathogen  and  its  genetic  make-up,  screening,  infection  control  and  antibiotic  stewardship  have  become  one  of  the  most  powerful
weapons in the fight to contain this threat.

The emergence of multidrug resistant pathogens has made the treatment of patients with UTIs a growing problem in the United States and internationally.
There are approximately 10 million patients each year in the United States with UTIs and more than one million of these patients have cUTI often requiring
hospitalization with intravenous antibiotic therapy. Among these patients E. coli represents the most common pathogen, and recent data indicate that 18.3%
of U.S. E. coli isolates are extended spectrum β-lactamase (ESBL) resistant. These patients present complicated therapeutic choices for clinicians and often
require last resort carbapenem antibiotics. The rate of ESBL resistant E. coli increased 34% annually between 2010 and 2014. Therapy with carbapenem
antibiotics has contributed to growing Carbapenem resistance (CRE) rates and high patient treatment costs.

Based  on  industry  analyses,  we  believe  the  global  HAI  market  is  a  $2  billion  dollar  market  with  the  molecular  diagnostic  segment  representing  a  fast-
growing segment of such market with multiple high acuity patients and significant infectious sites, including UTIs, surgical site infections, pneumonia and
bloodstream infections.

Commercial Sales

We currently sell and market our products and services directly in the United States through a dedicated sales and marketing support team. Internationally,
we sell our products through a network of 14 distributors covering 31 countries.

We operate in one segment. Our operations are located in the United States, Germany, and Austria.

Competition

We are developing a molecular diagnostics (MDx) business focused on leading a transformation in microbiology and infectious disease through precision
medicine products and services that combine genomic data and bioinformatics. Our approach combines proprietary platforms and content, namely the FDA
cleared and CE-IVD-marked Unyvero System and its DNA-based A50 Unyvero Panels, the FDA-cleared Acuitas AMR Gene Panel, and NGS applications
based on leading AI-powered AMR knowledge-bases. Our competitors include rapid diagnostic testing, next-generation sequencing testing, and traditional
microbiology  companies,  commercial  laboratories,  information  technology  companies,  and  hospital  laboratories  who  may  internally  develop  testing
capabilities. Principal competitive factors in our target market include: organizational size, scale, and breadth of product offerings; rapidity of test results;
quality and strength of clinical and analytical validation data and confidence in diagnostic results; cost effectiveness; ease of use; and regulatory approval
status.

Our  principal  competition  comes  from  traditional  methods  used  by  healthcare  providers  to  diagnose  and  screen  for  MDROs  and  from  other  molecular
diagnostic  companies  creating  screening  and  diagnostic  products  such  as  Cepheid  (a  subsidiary  of  Danaher),  Becton-Dickinson  (BD),  bioMérieux,
Accelerate  Diagnostics,  T2  Biosystems,  GenMark  (a  subsidiary  of  Roche),  Qiagen,  Luminex  (acquired  by  DiaSorin),  Thermo  Fisher  and  Mobidiag  (a
subsidiary of Hologic). We believe our focus on identifying antibiotic-resistant genes in addition to broad panels of organisms from a wide variety of native
clinical sample types, and our Ares Genetics bioinformatics offerings differentiate us from such competitors.

Competitors may develop their own versions of our product offerings in countries where we do not have patents or where our intellectual property rights
are not recognized.

Many of our potential competitors have widespread brand recognition and substantially greater financial, technical, research and development and selling
and marketing capabilities than we do. Others may develop products with prices lower than ours that could be viewed by hospitals, physicians and payers
as functionally equivalent to our products and services, or offer products and services at prices designed to promote market penetration, which could force
us  to  lower  our  list  prices  and  affect  our  ability  to  achieve  profitability.  If  we  are  unable  to  change  clinical  practice  in  a  meaningful  way  or  compete
successfully against current and future competitors, we may be unable to increase market acceptance and sales of our products, which could prevent us
from increasing our revenue or achieving profitability and could cause our stock price to decline.

Competition to the Unyvero System

The Unyvero Platform is a sample-to-answer MDx solution. There are several other companies who develop and commercialize similar systems. In terms
of  devices  and  assays,  OpGen  believes  its  key  competitors  include  bioMérieux  (BioFire  with  its  FilmArray®  platform),  GenMark  (now  a  subsidiary  of
Roche)  with  its  ePlex®  platform,  and  Accelerate  Diagnostics  with  its  Pheno™.  Taking  into  consideration  the  broader  market,  devices  of  other  key
competitors  can  be  extended  to  include  Cepheid  (GeneXpert®),  T2  Biosystems  (T2DX®),  Luminex  Corporation  (formerly  known  as  Nanosphere;  now
acquired  by  DiaSorin)  (Verigene  System®  and  Aries®),  Becton-Dickinson  (BD  Max™),  Binx  Health  (with  io™  System),  Roche  (Cobas®  Liat®  and
GeneWEAVE),  Qiagen  (QIAstat-Dx™),  Biocartis  N.V  (Idylla™),  Bosch  (Vivalytic  platform),  SpeeDx  (Plex/Resistance),  and  the  Meridian  Bioscience
(formerly  GenePOC)  Revogene®  system.  Disease-related  assay  competitors  including  those  providing  reagent  kits  only  (e.g.  Seegene,  Fast-Track
Diagnostics/Siemens Healthineers, Genetic Signatures) and LDT developers have to be separately assessed by each application. OpGen believes that its
Unyvero Platform has certain key characteristics that clearly differentiate it from other sample-to-answer systems.

Based  on  its  corporate  market  analysis,  OpGen  believes  that  due  to  the  proprietary  lysis  technology  its  Unyvero  Platform  is  able  to  process  a  broader
variety of sample types than competing platforms. In most cases, no labor or time intensive manual sample preparation is necessary and even difficult and
blood-contaminated native samples can be processed. Furthermore, the Unyvero Platform is CE-IVD-marked for a variety of samples including sputum,
bronchoalveolar lavage, tracheal aspirate, exudate, catheter tip, pus, sonication fluid, synovial fluid, swab and tissue. Further samples such as blood, urine,
stool  and  formalin-fixed  paraffin  embedded  tissues  present  further  options  for  extending  the  variety  of  samples  for  future  applications.  Fresh  or  frozen
samples as well as samples that have been stored in different media can be processed easily on the Unyvero Platform. As the lysis is integrated into the
workflow, hands-on time and potential handling errors are significantly reduced.

The Unyvero Platform is also differentiated from competing products by its high multiplexing capability based on end-point PCR, which allows for the
execution  of  eight  independent  multiplex  PCR  reactions  simultaneously.  Therefore,  Unyvero  can  identify  a  broad  range  of  microorganisms  and  a  large
variety of antibiotic resistance markers in a single run.

Focusing on severe infectious diseases and having developed an HPN Application Cartridge, an ITI Application Cartridge, a BCU Application Cartridge,
an IAI Application Cartridge and a UTI Application Cartridge and planning to develop further Application Cartridges (e.g. on the Unyvero A30 platform)
in the severe infectious disease area, Unyvero has a highly differentiated positioning in the market.

Although several direct competitors have in the past several years started to develop or commercialize their own infectious disease tests, OpGen believes
that the variety and breadth of its menu of cartridges targeting different infectious diseases positions it favorably to answer patient and customer needs.

Competition to the Unyvero Application Cartridges

Considering its panel design, the Company believes that there are currently few assays directly comparable to the Company’s HPN, LRT, LRT BAL, ITI,
IAI,  and  UTI  Unyvero  Application  Cartridges  that  are  commercially  available  to  date.  Various  competitors  offer  testing  in  some,  but  not  all,  of  the
infections targeted by Unyvero Application Cartridges. For example, for the HPN and LRT Application Cartridges, currently only two companies (OpGen
and bioMérieux/BioFire) offer an FDA-cleared IVD automated molecular panel for lower respiratory tract infections and pneumonia. According to publicly
available  sources,  Accelerate  Diagnostics  has  a  CE-IVD  pneumonia  assay  and  it  is  believed  to  be  planned  for  future  U.S.  FDA  submission.  Other
companies,  such  as,  Luminex  (formerly  Nanosphere;  now  DiaSorin),  GenMark  (now  Roche),  Seegene,  Genomica,  Miacom,  PathoFinder,  Fast-Track
Diagnostics (now a Siemens Healthineers company), Randox, ArcDia, Qiagen, and iCubate are primarily targeting the upper respiratory tract with their
panels. Their panels mainly cover viruses and a few bacteria, and in some occasions a limited number of antibiotic resistance markers only. Diatherix offers
a manual test claiming to cover both upper and lower respiratory infections. OpGen believes that it offers the most comprehensive panel for severe bacterial
pneumonia for critically ill patients that require hospitalization, as the panel includes unique and differentiated bacterial targets and the broadest coverage
of carbapenem resistance markers, while BioFire’s panel has a limited range of resistance markers and viral targets.

Competition by Conventional Microbiology

The conventional microbiology market consists of culture and MALDI-TOF based testing and is largely shared by well-established players including BD,
bioMérieux,  Bio-Rad  Laboratories,  Danaher  (Cepheid,  Beckman  Coulter),  Thermo  Fisher  Scientific.  Culture-based  testing  is  usually  performed  in  the
central  laboratory  at  TATs  of  48  to  72  h  and  it  is  yet  to  be  seen  whether  it  can  robustly  be  accelerated  by  miniaturization,  an  approach  pursued  by  the
company Accelerate Diagnostics and other companies developing rapid AST methods (Pattern Bioscience, Q-Linea ASTar, Lifescale, Specific Diagnostics
Reveal,  Gradientech,  oCelloScope),  as  well  as  efforts  to  achieve  AST  with  MALDI-TOF.  While  TATs  for  MALDI-TOF  based  testing  are  much  faster,
overall TATs from sample to report are still greater than 24 hours as MALDI-TOF generally depends on an initial culturing step for pathogen isolation and
cannot be performed from native patient samples. Generally, providers of conventional microbiology solutions are focusing on reducing TAT, use of labor
and lab space, as well as overall costs by automatic specimen processing and pathogen identification.

Competition by Molecular Diagnostics – PCR

Key players in the PCR-based molecular diagnostics market include bioMérieux, BD, Danaher, Roche, Qiagen, Abbott, Hologic, OpGen (including Curetis
GmbH),  amongst  others.  PCR-based  microbiology  testing  is  usually  performed  at  the  point  of  need  or  in  the  central  laboratory  at  rapidly  reduced  TAT
compared to conventional microbiology. Generally, providers of PCR-based molecular diagnostics are focusing on further reducing TAT to less than 30
minutes to one hour and/or increasing multi-plexing degree as well as reducing use of labor, lab space, and overall costs. The Company believes that its
ability to predict phenotypic antibiotic susceptibility based on the pathogen’s genetic profile complements PCR-based approaches detecting panels of genes
and mutations as indicators of resistance.

Competition to Ares Genetics

Ares  Genetics’  peers  and  competitors  include  companies  providing  conventional  microbiology,  PCR-  and  NGS  based  molecular  diagnostics,  as  well  as
AMR  databases  and  bioinformatics  solutions.  In  general,  many  peers  and  competitors  are  at  the  same  time  also  considered  potential ARESdb  licensing
partners  due  to  the  unique  content  and  positioning  of  ARES’  artificial  intelligence  curated  reference  database, ARESdb,  and  demonstrated  capability  to
predict phenotypic antibiotic susceptibility.

Competition by Molecular Diagnostics – NGS

The emerging NGS-based molecular diagnostics market is shared by start-up-like companies such as IDbyDNA, Karius, CosmosID, Noscendo, Day Zero
Diagnostics,  or  ArcBio  aiming  at  disrupting  the  molecular  microbiology  by  pathogen  detection  via  direct  sequencing  from  patient  samples,  as  well  as
established players such as bioMérieux focusing on isolate sequencing to monitor outbreaks in hospitals (in partnership with Illumina). NGS-based testing
is currently performed as a service and companies mostly focus on reducing TAT as well as increasing the NGS market share in molecular microbiology.
NGS-based  molecular  diagnostics  companies  are  considered  as  Ares  Genetics’  closest  competitors,  while  Ares  Genetics  believes  to  have  a  competitive
advantage  by  its  ability  to  predict  antibiotic  susceptibility  based  on  the  pathogen’s  genetic  profile  with  performance  meeting  FDA  requirements  for
functional testing of AST by culture.

Competing AMR Databases & Bioinformatics Solutions

To date, several AMR databases exist (e.g. CARD, PATRIC, etc.) but they are purely designed for academic research applications as they neither represent
IVD-grade  reference  databases,  nor  systematically  cover  high-resolution  resistance  profiles  including  confidence  levels  and  diagnostic  performance
parameters  for  associated  AMR  markers.  The  commercial  microbial  bioinformatics  solution  market  on  the  other  hand,  is  largely  covered  by  Qiagen,  a
strategic  licensing  partner  of  Ares  for  co-marketing  bioinformatics  research  solutions  based  on  ARESdb.  Start-ups  participating  in  this  market  include
companies such as 1928 Diagnostics or Ridom developing bioinformatics software for surveillance and outbreak analysis.

Research and Development

We intend to continue to invest in the development of additional Unyvero panels such as UTI for the Unyvero A50 platform, a Unyvero IJI panel, and we
intend to invest in the further development of the Unyvero A30 RQ platform, as well as the Ares Genetics bioinformatics solutions such as ARESdb and
ares-genetics.cloud.

Our ongoing and anticipated research and development efforts include:

·

·

·

·

Expanding the Ares Genetics bioinformatics and NGS offerings such as ARESdb, ares-genetics.cloud, ARESiss, ARESid, ARESupa etc.

Development of Unyvero A30 RQ platform

Clinical  trials  and  regulatory  filings  for  Unyvero  UTI  in  the  USA  (expected  as  De  Novo  with  clinical  trial  at  a  minimum  of  3  trial  sites  and
minimum of 1,500 samples tested)

Clinical  trials  and  regulatory  filings  for  Unyvero  IJI  in  the  USA  (expected  as  De  Novo  with  clinical  trial  at  a  minimum  of  3  trial  sites  and

Sales and Marketing

We currently sell and market our products and services directly in the United States through a dedicated sales and marketing support team. Internationally,
we sell our products through 14 distributors covering 31 countries.

Our strategy to build demand for our products following receipt of such regulatory clearance includes completing clinical verification studies, customer
driven evaluations and studies as well as sales of our tests for RUO purposes.

Customers

OpGen’s  commercial  teams  have  identified  several  stakeholder  groups:  treating  clinicians,  doctors  of  pharmacy  (PharmDs),  antibiotic  stewardship
programs, microbiologists, molecular biologists and laboratory managers as well as hospital administration, all of whom will be actively involved in the
purchase decision at varying levels and stages. In terms of product benefits, OpGen believes that clinicians and physicians seek timely diagnostic results
that can be used to better inform or confirm a treatment decision and improve patient outcomes, while microbiology laboratory managers, who have to
contend  with  the  steadily  decreasing  availability  of  trained  lab  technicians  and  the  need  to  perform  testing  during  off-shifts,  need  simple-to-use,  robust
technologies. Ultimately, however, the decision whether a proposed new testing solution is cost effective and affordable on a routine basis must be made by
the payer, which in the case of hospitalized inpatients under the DRG-reimbursement system is typically the hospital’s purchasing and finance departments.
OpGen’s key account management ensures that all stakeholders are targeted early and throughout the sales process.

Sales Process

OpGen  expects  that  the  entire  sales  process,  from  the  introductory  visit  to  the  point  in  time  when  the  hospital  begins  routinely  purchasing  Application
Cartridges or Acuitas consumables, known as the push-pull triangle model, which includes the lab, the clinicians and the finance entity, will take around six
to twelve months, based on the experience of competitors and peer companies, in the United States and about the same time from start to finish in the EU.
Depending on the time of year and budget cycle, however, a contractual arrangement can take significantly longer. An integral part of the sales process is
the placement of demo systems without payment for demo evaluation purpose.

OpGen’s  marketing  provides  sales  and  sales  support  tools  adapted  to  the  specifics  of  each  stakeholder  and  stimulates  demand  by  setting  up  awareness
campaigns  for  lab  personnel,  clinicians  and  general  hospital  stakeholders.  In  the  more  developed  markets  of  the  EU  and  the  RoW,  additional  customer
segmentation reflects the business opportunity per customer or institution and is linked to size of the hospital reflected in the number of beds available at
the institution. Therefore, the sales strategy is based on a key account management approach, initially only targeting large hospitals with clear focus on
departments like pulmonology/pneumology, large ICUs or orthopedics wards depending on the particular Application Cartridge of interest.

The  focus  is  on  high-volume  consumable  orders  (Application  Cartridges,  Acuitas  AMR  Gene  Panel  kits  and  other  consumables)  instead  of  driving
revenues  and  profits  through  hardware  placements  (Unyvero  System  or  EZ1/QS5  installations  for  Acuitas).  Consequently,  OpGen  and  its  distribution
partners aim to optimize the utilization of each placed hardware unit rather than solely maximizing the installed base of instruments. Therefore, OpGen,
with  its  tests  primarily  targeting  inpatients  (hospitalized)  with  severe  infections,  is  focusing  its  sales  and  commercialization  efforts  on  laboratories  in
hospitals and independent laboratories serving larger hospitals.

OpGen  and  its  distribution  partners  will  also  face  certain  market  entry  barriers  mostly  related  to  upfront  investments  for  the  implementation  of  its  new
technology, as most laboratories and microbiology centers are cost centers, which do not directly benefit from the current DRG reimbursement scheme.
Additionally,  the  Unyvero  and  Acuitas  platforms  will  be  an  add-on  test  not  replacing  traditional  testing  –  in  this  case  cultures,  which  are  perceived  as
comparatively cheap. Therefore, OpGen pursues a sales strategy whereby it offers customers a number of different financial options for its products and
services, including rental agreements (pursuant to which OpGen would provide the instruments on the basis that the customer commits to buying a certain
number of Application Cartridges or other consumables from OpGen over a set period of time, with the cost of such Application Cartridges or Acuitas
consumables incorporating a reagent rental charge for the use of the instrumentation), or a straight cash purchase of the Unyvero or Acuitas platforms, as
applicable. Similar concepts are employed by OpGen’s distribution partners at their discretion.

As OpGen is marketing its innovative Unyvero and Acuitas Platforms to a diverse and demanding customer base implementing solutions that offer the
potential  to  improve  upon  the  current  standard  of  care,  the  Company’s  management  believes  it  will  need  to  continue  making  additional  investments  in
clinical validation, scientific publications, brand awareness and market education worldwide, but with a focus in the EU and United States. Some of the
Company’s tests will require market access activities to prove their value and to obtain sufficient reimbursement by relevant payers for certain countries.

17 

 
 
 
 
 
 
 
 
 
 
 
 
OpGen has developed a full suite of marketing communications tools using print and online channels. OpGen also supplies supporting evidence for the
various individual stakeholders, for instance approaching microbiologists and clinicians with first-in-class scientific marketing. This not only includes the
classical marketing mix (i.e. a set of marketing tools regarding product, price, place and promotion), but also compiles information on health economics
and clinical outcomes research.

In  addition,  OpGen’s  marketing  focuses  on  medical  education  of  physicians  through  its  scientific  affairs  team,  participation  in  scientific  conferences,
organizing scientific sessions and symposia, and by publications in peer-reviewed journals.

In  order  to  receive  valuable  input  during  research  and  development,  stimulate  market  awareness  and  the  demand  for  its  products,  OpGen  has  made  a
significant investment in establishing clinical and scientific advisory boards in the United States, comprised of key opinion leaders. In addition, follow-on
research and clinical studies are conducted at key opinion leader, or KOL, sites, which assist in increasing market awareness. The KOL selection by OpGen
is based on the following criteria:

·
·
·

The KOL has a strong reputation in the area of infectious diseases and/or in molecular diagnostics;
The KOL is a key opinion leader in the clinical and/or laboratory space with strong influence on peers; and
The KOL is an 'early innovator', a member of a clinical society, an editor of scientific journals or a member of a guideline-setting agency and
could therefore act as a promoter of the product.

Distribution Channels

To distribute the Unyvero System and the Application Cartridges, OpGen has adopted a dual approach combining direct sales in the United States with
indirect sales through specialized distributors in European countries such as Germany, Switzerland, UK, France, Belgium, Netherlands, Luxemburg, Spain,
Italy,  Greece,  Portugal,  Austria,  Serbia,  Northern  Macedonia,  Bosnia  and  Herzegovina,  Montenegro,  Croatia,  Russia,  Belarus,  Ukraine,  Kazakhstan,
Romania, Kuwait, Egypt and Asian countries such as Singapore, Vietnam, China, Taiwan and Hong Kong and other markets such as Central and Latin
American markets such as Mexico and Colombia.

As of December 31, 2021, OpGen had an installed base of 195 Unyvero Analyzers across global markets.

The choice between direct sales and indirect sales distribution is based on available funding for OpGen’s commercial operations, the attractiveness of the
market in terms of size, pricing, and reimbursement, the ease of market access in terms of regulations, structure and complexity of the healthcare system,
and payer situation. Markets are also selected based on the availability of suitable distributors with appropriate size, portfolio, sales channels, experience,
networks, and reputation to introduce an innovative product like Unyvero in their respective market. It is also not uncommon for MDx companies to start
with a distributor model before going direct once economics permit establishing a direct sales infrastructure.

OpGen going forward will regularly evaluate on a case-by-case basis whether the chosen distribution channel is adequate to also cater for the new target
disease segments, or whether a new structure should be put in place.

Direct Sales U.S. Market

OpGen markets and sells the Unyvero and Acuitas platforms and will market any future cleared Application Cartridges and other consumables directly in
the United States through its own U.S.-based commercial organization including sales, marketing and after-sales support.

As of December 31, 2021, OpGen had an installed base of 30 Unyvero Analyzers across the United States and in different types of hospitals and labs.

Indirect Sales Markets

OpGen  enters  into  a  standard  distribution  agreement  with  most  of  its  Unyvero  distributors,  which  specifies  the  particular  Unyvero  products  and  the
respective  distribution  territory.  The  distribution  agreements  typically  contain  provisions  for  exclusive  distribution  within  a  particular  territory  and  for
specified term, typically from three to five-years. During that period, the distributor has exclusive rights to market, sell and distribute all Unyvero products.
In return, each distributor needs to commit to annual minimum purchases of Unyvero Systems as well as Application Cartridges. Transfer prices for the
Unyvero Systems and Application Cartridges are defined and reflect typical MDx industry distributor margins on consumable sales. If a distributor fails to
meet its annual minimum commitments fixed in the contract, the Company has the right to either terminate such agreement in its entirety, or to terminate
such distributor’s territory exclusivity in such country. Each of these agreements can be extended by mutual agreement between the parties. Furthermore,
the agreements also contain typical change of control provisions, which comprise a merger of the company, the sale of all assets or the liquidation of the
company.

18 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
OpGen, through its subsidiary Curetis, has entered into distribution agreements with 12 distributors covering 31 countries. Distribution agreements usually
feature  minimal  sales  commitments  and  purchase  commitments  of  the  Unyvero  Systems  and  Application  Cartridges  commensurate  with  the  size  and
structure of the respective market. The Company has several distribution agreements in place for the following European countries:

·

·
·
·
·

Austria,  Belgium,  France,  Germany,  Greece,  Italy,  Luxemburg,  Netherlands,  Portugal,  Spain,  Switzerland,  United  Kingdom:  A.  Menarini
Diagnostics;
Romania: Synttergy Consult LTD;
Russia, Ukraine, Kazakhstan: BioLine LLC;
Belarus: BioLine BS LLC; and
Bosnia and Hercegovina, Montenegro, Serbia, North Macedonia, Croatia: Ako Med d.o.o.

In connection with these distribution agreements, distributors are contractually obligated to:

cater for local product registrations as required;
perform local clinical studies as required;
take responsibility for local marketing based on guidelines and materials provided by Curetis’ global marketing team;
fulfil their regulatory and quality management system obligations as required;

·
·
·
·
· maintain a local inventory; and
·

install the Unyvero System, train customers, and provide first-level service.

Outside of the EU, OpGen currently plans to commercialize Unyvero also through distributors. Currently further distribution agreements are in place for
the following countries:

Kuwait: ATC;
Singapore: Acumen Research Laboratories;
China, Taiwan and Hong Kong: Beijing Clear Biotech/ Technomed (Hong Kong) Ltd;
Egypt: Future Horizons Scientific;

·
·
·
·
· Mexico: Quimica Valaner;
Colombia: Annar; and
·
Vietnam: Quang Phat Technology
·

The  total  contractual  minimum  purchase  requirements  of  all  current  distributors  is  382  Unyvero  Systems  of  which  about  350  are  part  of  BCB’s
commitment, which applies over an eight year period following NMPA approval, (plus approximately 1.5 million Application Cartridges which are also
part of BCB’s commitment during the same period). Failure of distributors to reach minimum purchase quantities has not led to any “forced” purchase of
the  minimum  quantities  in  the  past  but  can  lead  to  a  termination  of  the  distribution  agreements  or  termination  of  exclusivity  in  territories  for  such
distributor at the sole discretion of OpGen and its Curetis subsidiary. The above minimum purchase requirements do not guarantee any certain minimum
future levels of revenues.

With respect to after-sales support and maintenance, OpGen in some markets has established a concept of system replacement instead of onsite repair. In
the event of system failure or required maintenance, systems in such markets are rapidly replaced (within one or a few days), minimizing downtime for the
customer as well as reducing the need for a costly service organization. In certain instances, OpGen uses its own small field service engineering team to
provide ad hoc on-site repair and service. OpGen via its Curetis subsidiary has also trained field service engineers of several of our distribution partners so
that  they  can  perform  certain  repairs  and  services  themselves.  OpGen  expects  to  establish  a  service  maintenance  arrangement  where  customers  and
distributors pay for support and repair based on what service package they have purchased.

Manufacturing

During  2021,  we  manufactured  all  our  Unyvero  products  in  Germany  (Unyvero  systems  are  manufactured  by  Zollner  Elektronik  AG  and  Unyvero
cartridges and consumables at our own manufacturing facility in Bodelshausen, Germany), and all our FDA-cleared Acuitas AMR products in either our
previous Gaithersburg, Maryland facility or at our new headquarters in Rockville, Maryland. The Acuitas AMR product manufacturing has been moved to
the new site in Rockville, Maryland and is planned to get transferred to Curetis in Germany in 2022.

Manufacturing of our CE-IVD-marked and FDA-cleared products is performed under the respective applicable relevant current standards – Quality System
Regulation as required by the FDA or other relevant regulatory bodies for the manufacture of IVD labeled products. These regulations carefully control the
manufacture, testing and release of IVD products as well as raw material receipt and control. We also have ongoing Post Market surveillance and vigilance
responsibilities under applicable European and FDA regulations, and are subject to periodic inspections by the FDA or other relevant regulatory bodies to
determine compliance with the FDA’s or other applicable requirements, including primarily the quality system regulations and medical device reporting
regulations. The results of these inspections can include inspectional observations on FDA’s Form 483, warning letters, or other forms of enforcement.

For  instrument  manufacturing,  OpGen’s  subsidiary  Curetis  has  decided  to  co-develop  and  subsequently  outsource  all  of  its  Unyvero  A50  instrument
manufacturing  to  Zollner.  With  regard  to  Application  Cartridges,  they  are  developed  and  manufactured  entirely  in-house,  using  equipment  provided  by
Contexo and certain components provided by Scholz. Curetis has established a sophisticated manufacturing site for its cartridges where it has full control
over the entire production process ensuring that Application Cartridges meet stringent quality requirements.

Curetis’  EMS  (Electronic  Manufacturing  Services)  provider  Zollner  is  an  established  and  experienced  medical  device  manufacturer  for  large  global
companies and has flexible production processes ensuring it can meet demands with different volume requests. Zollner has established a Unyvero dedicated
manufacturing  island  and  Unyvero  team  where  in  a  single  eight-hour  shift  for  five  days  a  week,  up  to  four  systems  (Unyvero  L4  Lysator,  Unyvero  C8
Cockpit and Unyvero A50 Analyzer) can be assembled and tested per week. Zollner has an established 24/7 manufacturing operation, providing significant
capacities and capabilities for major scale-up of Unyvero manufacturing operations. The Company’s management believes that manufacturing capacity will
not  become  a  bottleneck  in  the  foreseeable  future.  Zollner  also  has  all  required  certifications  under  all  applicable  ISO  standards  for  IVD  instrument
manufacture and is an FDA registered establishment for the manufacturing of the Unyvero A50 instruments. To date, no decision has been made on the
selection of the OEM provider for the series production of the Unyvero A30 RQ systems. Unyvero A30 RQ  systems  are  so  far  being  produced  in  pilot
batches by DMTPe as development partner to Curetis in Germany.

As part of its operational strategy, OpGen’s subsidiary Curetis decided to build and operate its own manufacturing facility inside premises leased to it for
the manufacturing of the Application Cartridges. The Application Cartridge manufacturing facility based in Bodelshausen, Germany, has been operational
since 2011. Curetis is able to manufacture sufficient product to meet current and forecasted demand. OpGen expects future Application Cartridges to be
used with the Unyvero A30 RQ Analyzer for own research and development purposes, potential own MDx products of OpGen such as the Acuitas IVD
products and/or potential products by Unyvero A30 RQ licensees could also be manufactured in Bodelshausen, in a dedicated manufacturing line module to
be developed and built and using plastic parts manufactured by Scholz.

The  Curetis  facilities  at  Holzgerlingen,  Germany,  as  well  as  manufacturing  facility  in  Bodelshausen,  Germany  were  subject  to  an  FDA  inspection  in
February 2019, which was successfully completed with no FDA Form 483 observations.

Zollner

On May 27, 2009, OpGen’s subsidiary Curetis and Zollner Elektronik AG, Zandt, Germany, or Zollner, entered into a framework agreement, pursuant to
which Zollner performs certain development and manufacturing services for the Unyvero System. Under the terms of the agreement, each party retains
rights  to  its  respective  intellectual  property.  The  agreement  specifies  that  manufacturing  intellectual  property  created  jointly  or  solely  by  Zollner  while
performing work and services for Curetis shall be solely with Zollner. For any manufacturing intellectual property owned by Zollner, Curetis receives a
non-exclusive,  non-transferable,  world-wide,  royalty  free,  irrevocable  perpetual  license  (without  a  right  to  sublicense)  to  use,  provided  that  such
manufacturing intellectual property is embodied in a product provided to Curetis. As of today, there is no such manufacturing intellectual property. The
agreement is for an indefinite period of term and may be terminated with 12 months’ prior written notice.

20 

 
 
The framework agreement has been expanded by a development agreement in 2010 and related project agreements for various development projects as
well  as  by  a  strategic  supply  agreement  signed  in  June  2013  under  which  Zollner  became  the  OEM  contract  manufacturer  for  all  Unyvero  instrument
systems for Curetis.

Scholz

On February 1, 2013, Curetis and Horst Scholz GmbH & Co. KG, Kronach, Germany, or Scholz entered into a framework agreement, pursuant to which
Scholz  is  requested  to  perform  certain  services  in  the  area  of  tool  development  and  tool  making  (injection  molding  tools  to  make  plastic  parts)  and
manufacturing  product  components  (i.e.,  all  plastic  parts  for  the  Application  Cartridges)  for  Curetis.  The  parts  for  the  Unyvero  A50  products  include,
among other things, the base plates, valve plate, PCR chamber parts, spin column holder, waste chamber, reagent container, plungers and housing body
parts.  All  rights,  title,  interest  and  ownership  in  the  injection  molding  tools  and  plastic  products  specified  in  this  agreement,  including  the  respective
intellectual property rights shall be transferred and assigned to and solely belong to Curetis. Under this agreement, Scholz guarantees that all such rights
solely belong to Curetis. The framework agreement constitutes the legal basis for all legal relations between the parties after February 2013, in particular
for the supply agreement.

In addition to volume production with these pre-existing molds, Curetis subsequently commissioned a series of multi-cavity injection molds (owned by
Curetis yet stored and used on site at Scholz) under a strategic lease agreement with Scholz for all injection molded plastics parts entered into on July 28,
2015. The agreement is for an indefinite period of term and may be terminated with 12 months’ prior written notice or may be terminated earlier by Curetis
once the last order for related plastic parts has been fulfilled.

Under the framework agreement with Scholz, Curetis in 2018 also commissioned several single- and multi-cavity injection models for parts of the Unyvero
A30 RQ cartridge, namely molds for 'Frame bottom', 'Frame top', 'PCR Disc', 'Drive Ring', 'Switching Wheel bottom', 'Switching Wheel top', 'Sealing Ring
switching wheel' und 'Sealing Ring PCR disc'. These injection molds were developed, manufactured and put into service by Scholz over the course of 2018
and 2019 under the same terms as described above for the injection molds for the Unyvero A50 cartridges.

Supply Agreements

Curetis is party to a supply agreement with a large single-source supplier for purchase of PCR Master Mix reagent and other product components, which
are used as integral parts of Curetis’ Application Cartridges. Pursuant to the agreement, Curetis has the right to resell such product components supplied
under  the  agreement,  except  for  the  PCR  Master  Mix,  in  conjunction  and  jointly  repackaged  with  Curetis’  products  worldwide.  Further,  the  agreement
provides that Curetis has the right to resell the PCR Master Mix repackaged and refilled for use only in conjunction with Curetis’ products worldwide.
Pursuant  to  the  PCR  Master  Mix  supply  agreement,  Curetis’  distribution  right  is  limited  to  the  sale  to  end-users  and  Curetis’  distributors  and  does  not
include sales to users who re-sell Curetis products in modified form (e.g. using their own brand) or sales, which would violate any sanctions, embargos or
foreign trade restrictions issued by the EU or the United States Further, Curetis, or any of its affiliates or distributors, are not permitted to resell any of the
product components, including the PCR Master Mix, to third parties as stand-alone items for use other than in conjunction with Curetis’ products. Under
the agreement, Curetis is subject to certain minimum annual purchase requirements.

Raw Materials and Suppliers for Acuitas

OpGen procures PCR amplification reagents and the QuantStudio 5 Real-Time PCR System from Thermo Fisher Scientific. DNA purification reagents and
the EZ1 DNA Purification System are procured from Qiagen, NV. We also purchase our collection kits from sole-source suppliers. Some of these items are
unique  to  these  suppliers  and  vendors.  While  we  have  developed  alternative  sourcing  strategies  for  these  materials  and  vendors,  we  cannot  be  certain
whether these strategies will be effective or whether alternative sources will be available when we need them. If these suppliers can no longer provide us
with the materials we need to manufacture our Acuitas AMR Gene Panel products if the materials do not meet our quality specifications, or if we cannot
obtain acceptable substitute materials, our business would be negatively affected.

Seasonality of Business

We do not believe our business is subject to seasonality. However, our business can be subject to and affected by the business practices of our business
partners. To the extent that the availability of inventory or materials from or development practices of our partners is seasonal, our sales may be subject to
fluctuations quarter to quarter or year over year.

21 

 
 
Quality Assurance

Our quality and regulatory affairs functions oversee the quality of our research and development operations, laboratories and our FDA-cleared and CE-
IVD-marked diagnostic products as well as the quality systems used in research and development, manufacturing, and commercialization such as client
services, billing operations and sales and marketing. We have established quality management systems across our entire business, including implementation
and maintenance, document control, supplier qualification, corrective or preventive actions, oversight, and employee training processes. We monitor and
seek to improve our quality over time in compliance with all applicable regulations.

Payments and Reimbursements

Our  Unyvero  tests,  SARS-CoV-2  tests,  and  Acuitas  AMR  Gene  Panel  tests  are,  and  other  future  products  and  services  will  be,  sold  to  hospitals,
laboratories, and public health organizations as products and on a fee-for-service basis. When hospital and health system clients purchase our products, we
bill  them  directly  for  the  purchase  of  test  kits  and  consumables.  We  believe  that  hospitals  will  recoup  costs  of  our  products  and  services  by  obtaining
reimbursement from the government or private insurance companies for in-bed occupancies, which traditionally includes all testing required for admitted
patients.  When  our  tests  are  used  prior  to  hospital  admission,  hospitals,  clinical  laboratories,  and  other  healthcare  provider  customers  that  purchase  our
products may bill various third-party payers to cover all or a portion of the costs and fees associated with diagnostic tests, including the cost of the purchase
of our products.

In the IVD market, sales volumes and prices of innovative products will depend in large part on the availability of coverage and reimbursement from third-
party payers, which includes depending on public funding through governmental programs, private insurance plans and workers’ compensation plans. In
most healthcare settings, reimbursement schemes are complex, processes to achieve reimbursement for new technologies is tedious and time consuming
and payers may deny coverage or reimbursement. As a result, even though a new product may have been cleared for commercial distribution, it may find
limited  demand  for  the  product  until  reimbursement  approval  has  been  obtained  from  governmental  and  private  third-party  payers.  However,  specific
reimbursement  codes  for  laboratory  tests  are  in  most  countries  only  applicable  for  out-patient’s  healthcare.  In  addition,  some  public  funding  is  already
available in most countries for certain established tests and is often technology specific, thus code stacking or cross-walking and using corresponding codes
is quite usual to overcome challenging reimbursement situations.

OpGen  has  analyzed  existing  reimbursement  schemes  in  Germany,  Austria  and  Switzerland,  as  well  as  other  European  countries  and  the  United  States,
where hospitalized inpatients with severe infections are typically covered under the DRG system. With DRG, hospitals receive a lump-sum payment, e.g.,
up  to  €22,000  in  Germany  for  a  life-threatening  case  of  VAP  treated  in  intensive  care.  Therefore,  OpGen  has  taken  the  strategic  direction  to  target
hospitalized  patients  first  as  in  most  countries  DRG  systems  as  hospitals’  general  financing  are  in  place  covering  diagnostics  as  part  of  a  lump  sum
payment per patient without specific reimbursement codes for a laboratory test required.

In addition, the current list prices and future anticipated prices for Unyvero Application Cartridges and Acuitas AMR Gene Panel consumables, amount to
a small fraction of this overall DRG payment. It is also favorable in some countries, such as the United States, that pathogen identification by a lab test may
even warrant coding to higher DRG rates. For example, OpGen’s marketing team has been working with outside consultants to correctly position the LRT
Application Cartridge in the context of relevant DRG codes so that, based on the pathogens identified by the LRT Application Cartridge as the causative
agent of pneumonia but undetected by conventional microbiology, it can offer hospitals more favorable DRG coding and higher reimbursement on a per
patient case overall.

OpGen’s  management  believes  that  existing  DRG  reimbursement  scheme  codes  and  optimization  potential  based  on  a  Unyvero  or  Acuitas  diagnostic
within  those  applicable  DRGs  and  their  national  equivalents  can  be  used  in  most  major  markets  and  therefore  an  adoption  of  the  Unyvero  and  Acuitas
technology seems feasible.

Intellectual Property

In order to remain competitive, we must develop and maintain protection of the proprietary aspects of our technologies. To that end, in order to remain
competitive,  we  must  develop  and  maintain  protection  of  the  proprietary  aspects  of  our  technologies.  We  therefore  rely  on  a  combination  of  patents,
copyrights and trademarks, as well as contracts, such as confidentiality, invention assignment and licensing agreements. We also rely upon trade secret laws
to protect unpatented know-how and continuing technological innovation. In addition, we have what we consider to be reasonable security measures in
place to maintain confidentiality. Our intellectual property strategy is intended to develop and maintain our competitive position. 

As of December 31, 2021, OpGen had a patent portfolio of 55 granted patents and 12 patent applications. 32 of the granted patents and 4 of the pending
patent applications are from Curetis and 20 of the granted patents and 8 of the pending patent applications are from Ares Genetics.

As part of such portfolio, we have 3 granted U.S. patents related to our Acuitas products.

As part of the Company’s portfolio, there are 2 pending U.S. non-provisional patent applications and 8 issued U.S. patents related to our FISH products.
These issued patents begin to expire in November 2024 and will be fully expired by October 2033. We are currently in the process of sunsetting our FISH
intellectual property. 

We have ownership rights to 8 issued U.S. patents related to our legacy Argus products. These issued patents begin to expire in November 2026 and will be
fully expired by July 2031. We are currently in the process of sunsetting our Argus intellectual property. 

We  intend  to  file  additional  patent  applications  in  the  United  States  and  abroad  to  strengthen  our  intellectual  property  rights;  however,  our  patent
applications (including the patent applications listed above) may not result in issued patents in a timely fashion or at all, and we cannot assure investors that
any patents that have issued or might issue will protect our technology.

We require all employees and technical consultants working for us to execute confidentiality agreements, which provide that all confidential information
received  by  them  during  the  course  of  the  employment,  consulting  or  business  relationship  be  kept  confidential,  except  in  specified  circumstances.  Our
agreements  with  our  research  employees  provide  that  all  inventions,  discoveries  and  other  types  of  intellectual  property,  whether  or  not  patentable  or
copyrightable,  conceived  by  the  individual  while  he  or  she  is  employed  by  us  are  assigned  to  us.  We  cannot  provide  any  assurance,  however,  that
employees and consultants will abide by the confidentiality or assignment terms of these agreements. Despite measures taken to protect our intellectual
property, unauthorized parties might copy aspects of our technology or obtain and use information that we regard as proprietary.

Regulation

The following is a summary of the regulations materially affecting our business and operations.

Federal Oversight of Research-Use-Only Products

We currently offer for sale and sell some of our Unyvero tests to CROs, pharmaceutical companies, reference laboratories, hospitals and other health care
facilities for research use only (RUO). RUO and investigational use only, or IUO, products are not intended for human clinical use and must be properly
labeled in accordance with FDA guidance. Claims for RUOs and IUOs related to safety, effectiveness, or clinical utility or that are intended for human
diagnostic or prognostic use are prohibited. In November 2013, the FDA issued guidance titled “Distribution of In Vitro Diagnostic Products Labeled for
Research  Use  Only  or  Investigational  Use  Only  –  Guidance  for  Industry  and  Food  and  Drug  Administration  Staff.”  This  guidance  sets  forth  the
requirements to utilize such designations, labeling requirements and acceptable distribution practices, among other requirements.

Mere placement of an RUO or IUO label on an IVD product does not render the device exempt from otherwise applicable clearance, approval or other
requirements.  The  FDA  may  determine  that  the  device  is  intended  for  use  in  clinical  diagnosis  based  on  other  evidence,  including  how  the  device  is
marketed.

Our Unyvero UTI assay was launched for RUO purposes in Q2-2020. We cannot predict the potential effect the FDA’s current and forthcoming guidance
IUOs/RUOs  will  have  on  our  product  offerings  or  materials  used  to  perform  our  diagnostic  services.  We  cannot  be  certain  that  the  FDA  might  not
promulgate rules or issue guidance documents that could affect our ability to purchase materials necessary for the performance of our diagnostic services.
Should  any  of  the  reagents  obtained  by  us  from  vendors  and  used  in  conducting  our  diagnostic  services  be  affected  by  future  regulatory  actions,  our
business could be adversely affected by those actions, including increasing the cost of service or delaying, limiting or prohibiting the purchase of reagents
necessary to perform the service.

We cannot provide any assurance that FDA regulation, including premarket review, will not be required in the future for our surveillance and diagnostic
services, whether through additional guidance or regulations issued by the FDA, new enforcement policies adopted by the FDA or new legislation enacted
by  Congress.  We  expect  that  new  legislative  proposals  will  be  introduced  from  time  to  time.  It  is  possible  that  legislation  could  be  enacted  into  law  or
regulations  or  guidance  could  be  issued  by  the  FDA,  which  may  result  in  new  or  increased  regulatory  requirements  for  us  to  continue  to  offer  our
diagnostic services or to develop and introduce new services.

FDA’s Premarket Clearance and Approval Requirements

The FDA also has broad authority over the regulation of medical devices marketed for sale in the United States. The FDA regulates the research, clinical
testing,  manufacturing,  safety,  labeling,  storage,  recordkeeping,  premarket  clearance  or  approval,  promotion,  distribution  and  production  of  medical
devices. The FDA also regulates the export of medical devices manufactured in the United States to international markets.

Under the Food, Drug, and Cosmetic Act, or FDC Act, the FDA classifies medical devices into one of three classes: Class I, Class II or Class III. Devices
deemed to pose lower risk are placed into either Class I or Class II.

Class I devices are deemed to pose the lowest risk to the patient. Accordingly, Class 1 devices are subject to the lowest degree of regulatory scrutiny and
need  only  comply  with  the  FDA’s  General  Controls.  The  General  Controls  include  compliance  with  the  registration,  listing,  adverse  event  reporting
requirements, and applicable portions of the Quality System Regulation, or QSR as well as the general misbranding and adulteration prohibitions. Unless
specifically exempted in the regulations, general controls require a company that intends to market a Class I device, like us, to gain clearance for marketing
through the 510(k) process. Many Class I devices, however, are exempt from 510(k) clearance because their level of risk is low.

Class  II  devices  are  considered  higher  risk  devices  than  Class  I  devices.  Class  II  devices  are  subject  to  General  Controls  as  well  as  additional  special
controls. Special controls may include labeling requirements, mandatory performance standards, and post market surveillance. Generally, companies that
intend  to  market  Class  II  devices,  like  us,  must  comply  with  applicable  regulations  and  submit  a  510(k)  premarket  submission  for  review  to  receive
clearance to list and market their devices. The 510(k) must establish substantial equivalence to a predicate device. Some Class II devices are exempt from
filing a 510(k) but in some instances, Class II devices may be required to file a premarket approval, or PMA, application, for example, when changes in
their technology or intended use present novel risks that warrant separate review as a Class III medical device.

Class III devices are deemed by the FDA to pose the greatest risk, such as life-sustaining, life-supporting or implantable devices, or devices for which no
substantially equivalent previously cleared device exists and require a PMA before commercialization.

All medical device manufacturers must register their establishments and list their devices with the FDA. Establishment registration requires the payment of
user fees. In addition, both 510(k) premarket submissions and PMA applications are subject to the payment of user fees, paid at the time of submission for
FDA review.

510(k) Clearance Pathway

Where applicable, we are working towards submitting our Unyvero tests for clearance under Section 510(k) of the FDC Act. Such tests are classified as
medical devices, and we have to submit a premarket notification demonstrating that the 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 premarket
approval  applications.  FDA’s  510(k)  clearance  pathway  usually  takes  from  three  to  twelve  months;  by  statute,  the  FDA  has  90  days  to  review  the  pre-
market notification. On average the review time is approximately six months, but it can take significantly longer than twelve months in some instances (e.g.
in  the  case  of  the  Acuitas  AMR  Gene  Panel  as  well  as  original  Unyvero  LRT  products  a  total  of  over  18  months),  as  the  FDA  may  require  additional
information, including clinical data, to make a determination regarding substantial equivalence.

After 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, require a PMA. The FDA requires each manufacturer to
determine whether the proposed change requires submission of a new 510(k) notice, or a premarket approval, but the FDA can review any such decision
and can disagree with a manufacturer’s determination. If the FDA disagrees with a manufacturer’s determination, the FDA can require the manufacturer to
cease marketing and/or recall the modified device until 510(k) clearance or premarket approval is obtained. If the FDA requires us to seek 510(k) clearance
or premarket approval for any modifications to a previously cleared product, we may be required to cease marketing or recall the modified device until we
obtain this clearance or approval. Also, in these circumstances, we may be subject to significant regulatory fines or penalties. We have made, and plan to
continue to make, additional product enhancements to products that we believe do not require new 510(k) clearances, but we cannot guarantee that the
future enhancements, should they occur, will be exempt from new 510(k) clearances.

24 

 
 
De Novo Classification Request

The Food and Drug Administration Modernization Act of 1997, or FDAMA, added the De Novo classification option as an alternate pathway to classify
low to moderate risk novel medical devices that had automatically been placed in Class III after receiving a not substantially equivalent determination in
response  to  a  premarket  notification  510(k)  submission.  FDAMA  also  permits  a  sponsor  to  submit  a  De  Novo  classification  request  to  the  FDA  for  a
product otherwise requiring a PMA application without first being required to submit a 510(k) application. The De Novo classification process is generally
more costly and time consuming than the 510(k) process. The first Unyvero application cartridge product had been subject to the De Novo process and we
expect the Unyvero UTI and IJI to also fall under the De Novo process.

Premarket Approval Pathway

A PMA application must be submitted if a device cannot be cleared through the 510(k) process. The PMA application process is generally more costly and
time  consuming  than  the  510(k)  process.  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.

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 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  premarket  approval  applications  or  premarket  approval  application
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 the 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 may not require as extensive clinical data or the convening of an advisory panel. None
of our products are currently approved under a premarket approval.

Clinical Trials

Clinical trials are almost always required to support a De Novo or PMA application and are usually required to support non-exempt Class I and Class II
510(k)  premarket  submissions.  Clinical  trials  may  also  be  required  to  support  certain  marketing  claims.  If  the  device  presents  a  “significant  risk,”  as
defined by the FDA, to human health, the FDA requires the device sponsor to file an investigational device exemption, or IDE application with the FDA
and  obtain  IDE  approval  prior  to  conducting  the  human  clinical  trials.  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.  The  IDE  application  must  be  approved  in  advance  by  the  FDA  prior  to
initiation of enrollment of human subjects. Clinical trials for a significant risk device may begin once the investigational device exemption application is
approved  by  the  FDA.  If  the  clinical  trial  design  is  deemed  to  be  “non-significant  risk,”  the  clinical  trial  may  be  eligible  for  the  “abbreviated”  IDE
requirements; in some instances IVD clinical trials may be exempt from the more burdensome IDE requirements if the test uses a noninvasive sampling
method, does not introduce energy into the subject, and is not used in a diagnostic procedure without confirmation of the diagnosis by another established
medically  diagnostic  procedure  or  product.  All  clinical  trials  conducted  to  support  a  premarket  submission  must  be  conducted  in  accordance  with  FDA
regulations and Federal and state regulations concerning human subject protection, including informed consent, oversight by an IRB and healthcare privacy
requirements. A clinical trial may be suspended by the FDA or the IRB 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, the results of our clinical testing may not demonstrate
the safety and efficacy of the device or may be equivocal or otherwise not be sufficient to obtain approval of our product. Similarly, in Europe the clinical
study must be approved by the local ethics committee and in some cases, including studies of high-risk devices, by the Ministry of Health in the applicable
country.

25 

 
 
 
 
 
Pervasive and Continuing FDA Regulation

Numerous regulatory requirements apply to products classified as devices, such as ours, and would continue to apply. These include:

·
·

·
·

product listing and establishment registration, which helps facilitate FDA inspections and other regulatory action;
QSR,  which  requires  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 design 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.

OpGen’s Rockville, Maryland facility is currently registered as a manufacturer with the FDA to manufacture our Acuitas products, whereas the Curetis
facility  in  Bodelshausen,  Germany  is  registered  with  the  FDA  for  all  Unyvero  cartridge  and  consumable  manufacturing.  We  and  any  third-party
manufacturers are subject to announced and unannounced inspections by the FDA to determine our compliance with quality system regulation and other
regulations.

Failure  to  comply  with  applicable  regulatory  requirements  could  result  in  enforcement  action  by  the  FDA,  which  might  include  any  of  the  following
sanctions: (1) untitled letters, Form 483 observations, warning letters, fines, injunctions, consent decrees and civil penalties; (2) unanticipated expenditures
to  address  or  defend  such  actions;  (3)  customer  notifications  for  repair,  replacement  and  refunds;  (4)  recall,  detention  or  seizure  of  our  products;  (5)
operating  restrictions  or  partial  suspension  or  total  shutdown  of  production;  (6)  refusing  or  delaying  our  requests  for  De  Novo  classification,  510(k)
clearance or premarket approval of new products or modified products; (7) operating restrictions; (8) withdrawing granted De Novo classifications, 510(k)
clearances or PMA approvals that have already been granted; (9) refusal to grant export approval for our products; or (10) criminal prosecution.

After a medical device is placed on the market, numerous regulatory requirements apply. These include: all of the relevant elements of the QSR, labeling
regulations, restrictions on promotion and advertising, the medical device reporting (which requires the manufacturer to report to the FDA if its device may
have caused or contributed to a death or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if it were
to recur), the Reports of Corrections and Removals regulations (which requires manufacturers to report certain recalls and field actions to the FDA), and
other post-market requirements.

Health Insurance Portability and Accountability Act

Under  HIPAA,  the  Department  of  Health  and  Human  Services,  or  HHS,  has  issued  regulations  to  protect  the  privacy  and  security  of  protected  health
information used or disclosed by healthcare providers, such as us, and by certain vendors of ours, also known as our business associates. The regulations
include limitations on the use and disclosure of protected health information and impose notification requirements in the event of a breach of protected
health  information.  HIPAA  also  regulates  standardization  of  data  content,  codes  and  formats  used  in  healthcare  transactions  and  standardization  of
identifiers for health plans and providers. Penalties for violations of HIPAA regulations include civil and criminal penalties.

We have developed and implemented policies and procedures designed to comply with these regulations. The requirements under these regulations may
change periodically and could have an effect on our business operations if compliance becomes substantially more costly than under current requirements.

26 

 
 
In  addition  to  Federal  privacy  regulations,  there  are  a  number  of  state  laws  governing  confidentiality  of  health  information  that  are  applicable  to  our
business. If our business expands internationally, we would be subject to compliance with other laws regarding confidentiality of health information and
privacy.

New laws governing privacy may be adopted in the future as well. We have taken steps to comply with health information privacy requirements to which
we are aware that we are subject. However, we cannot assure you that we are or will remain in compliance with diverse privacy requirements in all of the
jurisdictions in which we do business. Failure to comply with privacy requirements could result in civil or criminal penalties, which could have a materially
adverse effect on our business.

Federal and State Physician Self-referral Prohibitions

As a manufacturer and seller of diagnostic tests, we are subject to the Federal physician self-referral prohibitions, commonly known as the Stark Law, and
to  similar  restrictions  under  the  Maryland  Physician  Self-Referral  Law.  Together,  these  restrictions  generally  prohibit  us  from  billing  a  patient  or  any
governmental or private payor for any clinical laboratory services when the physician ordering the service, or any member of such physician’s immediate
family, has an investment interest in or compensation arrangement with us, unless the arrangement meets an exception to the prohibition.

Both  the  Stark  Law  and  the  Maryland  Physician  Self-Referral  Law  contain  an  exception  for  compensation  paid  to  a  physician  for  personal  services
rendered by the physician. We have compensation arrangements with a number of physicians for personal services, such as clinical advisory board services,
speaking engagements and other consulting activities. We have structured these arrangements with terms intended to comply with the requirements of the
personal services exception to the Stark Law and the Maryland Physician Self-Referral Law.

However, we cannot be certain that regulators would find these arrangements to be in compliance with the Stark Law, the Maryland Physician Self-Referral
Law, or similar state laws. We would be required to refund any payments we receive pursuant to a referral prohibited by these laws to the patient, the payor
or the Medicare program, as applicable.

Sanctions for a violation of the Stark Law include the following:

·
·
·
·
·

denial of payment for the services provided in violation of the prohibition;
refunds of amounts collected by an entity in violation of the Stark Law;
a civil penalty of up to $15,000 for each service arising out of the prohibited referral;
possible exclusion from Federal healthcare programs, including Medicare and Medicaid; and
a civil penalty of up to $100,000 against parties that enter into a scheme to circumvent the Stark Law’s prohibition.

These prohibitions apply regardless of the reasons for the financial relationship and the referral. No finding of intent to violate the Stark Law is required for
a violation. In addition, knowing violations of the Stark Law may also serve as the basis for liability under the Federal False Claims Act, which prohibits
knowingly presenting, or causing to be presented, a false or fraudulent claim for payment to the U.S. Government.

Further, if we submit claims in violation of the Maryland Physician Self-Referral Law, we can be held liable to the payer for any reimbursement received
for  the  services  by  us.  Finally,  other  states  have  self-referral  restrictions  with  which  we  have  to  comply  that  differ  from  those  imposed  by  Federal  and
Maryland  law.  While  we  have  attempted  to  comply  with  the  Stark  Law  and  the  Maryland  Physician  Self-Referral  Law,  it  is  possible  that  some  of  our
financial arrangements with physicians could be subject to regulatory scrutiny at some point in the future, and we cannot provide assurance that we will be
found to be in compliance with these laws following any such regulatory review.

Federal and State Anti-Kickback Laws

The  Federal  healthcare  program  Anti-Kickback  Law  makes  it  a  felony  for  a  person  or  entity  to  knowingly  and  willfully  offer,  pay,  solicit  or  receive
remuneration,  directly  or  indirectly,  in  order  to  induce  business  that  is  reimbursable  under  any  Federal  healthcare  program.  A  violation  of  the  Anti-
Kickback  Law  may  result  in  imprisonment  for  up  to  five  years  and  fines  of  up  to  $250,000  in  the  case  of  individuals  and  $500,000  in  the  case  of
organizations. Convictions under the Anti-Kickback Law result in mandatory exclusion from Federal healthcare programs for a minimum of five years. In
addition, HHS has the authority to impose civil assessments and fines and to exclude healthcare providers and others engaged in prohibited activities from
Medicare,  Medicaid  and  other  Federal  healthcare  programs.  Actions  which  violate  the  Anti-Kickback  Law  also  incur  liability  under  the  Federal  False
Claims Act.

27 

 
 
 
Although the Anti-Kickback Law applies only to Federal healthcare programs, a number of states, including Maryland, have passed statutes substantially
similar  to  the  Anti-Kickback  Law  pursuant  to  which  similar  types  of  prohibitions  are  made  applicable  to  all  other  health  plans  and  third-party  payers.
Violations of Maryland’s anti-kickback law are punishable by tiered criminal penalties based on the crime with a maximum penalty of life imprisonment
and fines of up to $200,000, or both. Civil penalties include three times the amount of any overpayment made in violation of the statute.

Federal  and  state  law  enforcement  authorities  scrutinize  arrangements  between  healthcare  providers  and  potential  referral  sources  to  ensure  that  the
arrangements are not designed as a mechanism to induce patient care referrals or induce the purchase or prescribing of particular products or services. The
law enforcement authorities, the courts and Congress have also demonstrated a willingness to look behind the formalities of a transaction to determine the
underlying purpose of payments between healthcare providers and actual or potential referral sources. Generally, courts have taken a broad interpretation of
the scope of the Anti-Kickback Law, holding that the statute may be violated if merely one purpose of a payment arrangement is to induce referrals or
purchases.

In addition to statutory exceptions to the Anti-Kickback Law, regulations provide for a number of safe harbors. If an arrangement meets the provisions of a
safe harbor, it is deemed not to violate the Anti-Kickback Law. An arrangement must fully comply with each element of an applicable safe harbor in order
to qualify for protection. There are no regulatory safe harbors to the Maryland anti-kickback law.

Among  the  safe  harbors  that  may  be  relevant  to  us  is  the  discount  safe  harbor.  The  discount  safe  harbor  potentially  applies  to  discounts  provided  by
providers  and  suppliers,  including  laboratories,  to  physicians  or  institutions.  If  the  terms  of  the  discount  safe  harbor  are  met,  the  discounts  will  not  be
considered prohibited remuneration under the Anti-Kickback Law. Maryland does not have a discount safe harbor.

The personal services safe harbor to the Anti-Kickback Law provides that remuneration paid to a referral source for personal services will not violate the
Anti-Kickback Law provided all of the elements of that safe harbor are met. One element is that if the agreement is intended to provide for the services of
the physician on a periodic, sporadic or part-time basis, rather than on a full-time basis for the term of the agreement, the agreement must specify exactly
the schedule of such intervals, their precise length, and the exact charge for such intervals.

Our personal services arrangements with some physicians may not meet the specific requirement of this safe harbor that the agreement specify exactly the
schedule of the intervals of time to be spent on the services because the nature of the services, such as speaking engagements, does not lend itself to exact
scheduling  and  therefore  meeting  this  element  of  the  personal  services  safe  harbor  is  impractical.  Failure  to  meet  the  terms  of  the  safe  harbor  does  not
render  an  arrangement  illegal.  Rather,  the  government  may  evaluate  such  arrangements  on  a  case-by-case  basis,  taking  into  account  all  facts  and
circumstances.

While  we  believe  that  we  are  in  compliance  with  the  Anti-Kickback  Law  and  the  Maryland  anti-kickback  law,  there  can  be  no  assurance  that  our
relationships with physicians, academic institutions and other customers will not be subject to investigation or challenge under such laws. If imposed for
any reason, sanctions under the Anti-Kickback Law and the Maryland anti-kickback law could have a negative effect on our business.

Other Federal and State Fraud and Abuse Laws

In  addition  to  the  requirements  discussed  above,  several  other  healthcare  fraud  and  abuse  laws  could  have  an  effect  on  our  business.  For  example,
provisions  of  the  Social  Security  Act  permit  Medicare  and  Medicaid  to  exclude  an  entity  that  charges  the  Federal  healthcare  programs  substantially  in
excess of its usual charges for its services. The terms “usual charge” and “substantially in excess” are ambiguous and subject to varying interpretations.

Further, the Federal False Claims Act prohibits a person from knowingly submitting a claim, making a false record or statement in order to secure payment
or retaining an overpayment by the Federal government. In addition to actions initiated by the government itself, the statute authorizes actions to be brought
on behalf of the Federal government by a private party having knowledge of the alleged fraud, also known as qui tam lawsuits. Because the complaint is
initially  filed  under  seal,  the  action  may  be  pending  for  some  time  before  the  defendant  is  even  aware  of  the  action.  If  the  government  is  ultimately
successful in obtaining redress in the matter or if the plaintiff succeeds in obtaining redress without the government’s involvement, then the plaintiff will
receive a percentage of the recovery. It is not uncommon for qui tam lawsuits to be filed by employees, competitors or consultants.

Finally, the Social Security Act includes its own provisions that prohibit the filing of false claims or submitting false statements in order to obtain payment.
Violation of these provisions may result in fines, imprisonment or both, and possible exclusion from Medicare or Medicaid programs. Maryland has an
analogous state false claims act applicable to state health plans and programs, as do many other states.

International Regulation

Sales of diagnostic tests like our Unyvero tests and SARS CoV-2 test kits outside the United States would be subject to foreign government regulations,
which vary substantially from country to country. In order to market our products in other countries, we would need to obtain regulatory approvals and
comply  with  extensive  safety  and  quality  regulations  in  other  countries.  OpGen  currently  distributes  its  Unyvero  products  ex  U.S.  via  a  network  of
distribution partners. The time required to obtain approval by a foreign country may be longer or shorter than that required for FDA clearance or approval,
and the requirements may differ significantly. If we elect to, or are required to, seek clearance of or approval for any of our products from the FDA, we may
be able to commercialize such products with shorter lead time in international markets, but would need to establish international operations in order to do
so.

Environmental Matters

Our  operations  require  the  use  of  hazardous  materials  (including  biological  materials)  which  subject  us  to  a  variety  of  Federal,  state  and  local
environmental and safety laws and regulations. Some of these regulations provide for strict liability, holding a party potentially liable without regard to
fault  or  negligence.  We  could  be  held  liable  for  damages  and  fines  as  a  result  of  our,  or  others’,  business  operations  should  contamination  of  the
environment or individual exposure to hazardous substances occur. We cannot predict how changes in laws or new regulations will affect our business,
operations or the cost of compliance.

Human Capital Resources

As of December 31, 2021, we had 99 employees worldwide, with 31 employed in the United States, 54 employed in Germany at Curetis GmbH, and 14
employed  in  Austria  at  Ares  Genetics  GmbH.  Of  our  99  worldwide  employees,  91  are  full-time  employees.  Except  for  the  managing  director  of  Ares
Genetics, our Austrian-based employees are subject to a collective bargaining agreement for employees of companies in the automated data processing and
IT services industry. None of our other employees worldwide are subject to a collective bargaining arrangement. The 31 employees in the United States
primarily work in our Rockville, Maryland location or are field based marketing, sales, and service employees.

We compete in the highly competitive healthcare and life sciences industry. Our ability to operate and compete effectively and execute our strategy requires
us  to  attract,  develop  and  retain  talented  personnel  for  positions  in  research,  quality  assurance,  clinical,  commercial  and  other  positions.  Recruiting  and
retaining our personnel depends on factors, such as compensation and benefits, development and career opportunities, and work culture and environment.
We accordingly invest in our employees in a number of different ways.

Culture

Our goal is to create and foster a culture of high performance and accountability through the attraction, retention and development of expert talent. We
compete for top talent with effective recruitment strategies, well defined roles and attractive total compensation packages. We keep talent engaged through
appreciation, communication and creation of a great work environment based on our shared core values at OpGen: Ownership, Performance, Generosity,
Enthusiasm, Now! We support employee growth professionally and personally through formal and informal opportunities and leadership support.

Compensation

In addition to competitive base salaries, we offer incentive-based compensation programs tied to the performance of key objectives. We also provide
compensation in the form of restricted stock unit grants and stock options.

Health & Wellness

The physical health and wellbeing, life balance and mental health of our employees is vital to our success. Throughout 2021, health and wellness was a key
focus of the Company, especially in light of the pandemic. Many of our employee communications focused on the physical and mental health of our
employees. We remain committed to providing our workforce with flexible remote working schedules to suit their personal needs through this challenging
time. We also continue to benchmark all of our health insurance offerings to ensure plan competitiveness.

Throughout the COVID-19 pandemic, employee safety is of top priority. Many of our employees globally have been working from home since the
beginning of the pandemic, except for those with a business need to engage in work onsite. Ongoing safety measures were put into place at each of our
locations including implementing pre-screening and social distancing requirements in addition to providing PPE and regular testing of staff wherever
possible.

Item 1A. Risk Factors

The following are significant factors known to us that could materially harm our business, financial condition or operating results or could cause our actual
results  to  differ  materially  from  our  anticipated  results  or  other  expectations,  including  those  expressed  in  any  forward-looking  statement  made  in  this
Annual Report. The risks described are not the only risks we face. Additional risks and uncertainties not currently known to us, or that we currently deem
to  be  immaterial,  also  may  adversely  affect  our  business,  financial  condition  and  operating  results.  If  any  of  these  risks  actually  occur,  our  business,
financial condition, and operating results could suffer significantly.

Summary

Below is a summary of material factors that make an investment in our securities speculative or risky. Importantly, this summary does not address all of the
risks that we face. We encourage you to carefully review the full risk factors contained in this Annual Report in their entirety for additional information
regarding the material factors that make an investment in our securities speculative or risky.

· We have a history of losses, and we expect to incur losses for the next several years.

· We will require additional capital to fund our operations, and if we fail to obtain necessary financing, we may not be able to continue as a going

concern.

· We  face  significant  competition  from  other  biotechnology  and  pharmaceutical  companies,  and  our  operating  results  will  suffer  if  we  fail  to

compete effectively.

· We may never successfully develop, receive regulatory clearance or approval for or commercialize our new products.

·

·

·

Our products and services may never achieve significant commercial market acceptance.

The COVID-19 pandemic has adversely impacted our business, financial condition and results of operations.

Changes  in  healthcare  laws  policies,  including  legislation  reforming  the  U.S.  healthcare  system,  may  have  a  material  adverse  effect  on  our
financial condition and operations.

· We rely on collaborations with third parties to develop product and services candidates. If these collaborations are not successful, our business

could be adversely affected.

·

·

Our future success is dependent upon our ability to expand our customer base.

If we are unable to protect our intellectual property effectively, our business will be harmed.

Risks Related to Our Business

We have a history of losses, and we expect to incur losses for the next several years. The report of our independent registered public accounting firm on
our financial statements for the years ended December 31, 2021 and 2020 contains explanatory language that substantial doubt exists about our ability
to continue as a going concern.

We have incurred substantial losses since our inception, and we expect to continue to incur additional losses for the next several years. For the years ended
December 31, 2021 and 2020, we had net losses of $34.8 million and $26.2 million, respectively. From our inception through December 31, 2021, we had
an accumulated deficit of $235.5 million. The reports of our independent registered public accounting firm on our financial statements for the years ended
December  31,  2021  and  2020  each  contain  explanatory  language  that  substantial  doubt  exists  about  our  ability  to  continue  as  a  going  concern.  We
completed a number of financings in 2020 and 2021, including an at-the-market public offering which commenced in February 2020 (the “ATM Offering”),
a private placement in November 2020, a registered direct financing in February 2021, a warrant exercise and exchange transaction in March 2021, and a
registered direct financing in October 2021. The net proceeds from such financings were approximately $82.0 million. We cannot assure you that we can
continue to raise the capital necessary to fund our business.

Even if we achieve significant revenues, we may not become profitable, and even if we achieve profitability, we may not be able to sustain or increase
profitability on a quarterly or annual basis. Our failure to become and remain consistently profitable could adversely affect the market price of our common
stock  and  could  significantly  impair  our  ability  to  raise  capital,  expand  our  business  or  continue  to  pursue  our  growth  strategy.  We  have  no  committed
sources of capital and may find it difficult to raise money on terms favorable to us or at all. The failure to obtain sufficient capital to support our operations
would have an adverse effect on our business, financial condition and results of operations.

32 

 
 
We need to raise additional capital to support our business. If we cannot do so successfully, we will not be able to continue as a going concern.

We need to raise additional capital to support our business. If we cannot do so successfully, we will not be able to continue as a going concern. To meet our
capital needs, we are considering multiple alternatives, including, but not limited to, the ATM Offering, additional equity financings, debt financings and
other funding transactions, licensing and/or partnering arrangements and business combination transactions. We believe that additional equity financings
are the most likely source of capital. There can be no assurance that we will be able to complete any such financing transaction on acceptable terms or
otherwise.

We believe that additional equity or debt financings are the most likely source of capital going forward. There can be no assurance that we will be able to
complete any such financing transaction on acceptable terms or otherwise.

We believe that current cash on hand will be sufficient to fund operations into the fourth quarter of 2022, including repayment of the first tranche of the
EIB loan facility of approximately $15 million due in April 2022.  In the event we are unable to successfully raise additional capital during or before the
fourth quarter of 2022, we will not have sufficient cash flows and liquidity to finance our business operations as currently contemplated. Accordingly, in
such  circumstances  we  would  be  compelled  to  immediately  reduce  general  and  administrative  expenses  and  delay  research  and  development  projects,
including  the  purchase  of  scientific  equipment  and  supplies,  until  we  are  able  to  obtain  sufficient  financing.  If  such  sufficient  financing  is  not  received
timely,  we  would  then  need  to  pursue  a  plan  to  license  or  sell  assets,  seek  to  be  acquired  by  another  entity,  cease  operations  and/or  seek  bankruptcy
protection.

Following  the  combination  of  the  OpGen  and  Curetis  businesses  we  may  not  see  the  growth  and  success  of  the  combined  OpGen  business  that  we
believe will occur.

Although we believe the combination of the OpGen and Curetis businesses provides a significant commercial opportunity for growth, we may not realize
all of the synergies that we anticipate and may not be successful in implementing our commercialization strategy across all products and platforms as well
as all geographies. Our combined business will be subject to all of the risks and uncertainties inherent in the pursuit of growth in our industry and we may
not  be  able  to  successfully  sell  our  products,  obtain  the  regulatory  clearances  and  approvals  we  apply  for  or,  realize  the  anticipated  benefits  from  our
distribution,  collaboration  and  other  commercial  partners.  If  we  are  not  able  to  grow  the  combined  business  of  OpGen  as  a  commercial  enterprise,  our
financial condition will be negatively impacted.

The process to obtain and maintain FDA clearances or approvals for our products is complex and time and resource consuming. If we fail to obtain
such clearances or approvals, our business and results of operations will be materially adversely impacted.

The  process  of  obtaining  regulatory  clearances  or  approvals  to  market  a  medical  device  can  be  costly  and  time  consuming,  and  we  may  not  be  able  to
obtain these clearances or approvals on a timely basis, if at all. We were subject to extended delays for the FDA clearance of our Acuitas AMR Gene Panel
test due to the national emergency situation caused by the COVID-19 pandemic and FDA prioritizing COVID related product reviews. The FDA has not
yet been able to provide any feedback in the form of presub meetings for either the Unyvero UTI or IJI panels and has recently declined to host any presub
meetings for IJI in early 2022. In addition, the time and expense needed to prepare future clinical trial data for submission to the FDA and reviewing and
responding  to  the  FDA’s  request  for  additional  information  may  require  significant  resources  and  could  impact  other  research  and  development  project
timelines, which may adversely affect our strategy and ability to commercialize our diagnostic tests and bioinformatics products and services.

We expect our ability to utilize our net operating loss carryforwards will be limited as a result of an “ownership change,” as defined in Section 382 of
the Internal Revenue Code triggered by consummation of the transaction with Curetis.

As  of  December  31,  2021,  we  had  approximately  $202  million  of  net  operating  loss,  or  NOL,  carryforwards  for  U.S.  federal  tax  purposes.  Under  U.S.
federal income tax law, we generally can use our NOL carryforwards (and certain tax credits) to offset ordinary taxable income, thereby reducing our U.S.
federal income tax liability, for up to 20 years from the year in which the losses were generated, after which time they will expire. State NOL carryforwards
(and certain tax credits) generally may be used to offset future state taxable income for 20 years from the year in which the losses are generated, depending
on the state, after which time they will expire. The rate at which we can utilize our NOL carryforwards is limited (which could result in NOL carryforwards
expiring prior to their use) each time we experience an “ownership change,” as determined under Section 382 of the Internal Revenue Code. A Section 382
ownership change generally occurs if a shareholder or a group of shareholders who are deemed to own at least 5% of our common stock increase their
ownership by more than 50 percentage points over their lowest ownership percentage within a rolling three-year period. If an ownership change occurs,
Section 382 generally would impose an annual limit on the amount of post-ownership change taxable income that may be offset with pre-ownership change
NOL carryforwards equal to the product of the total value of our outstanding equity immediately prior to the ownership change (reduced by certain items
specified in Section 382) and the U.S. federal long-term tax-exempt interest rate in effect at the time of the ownership change. A number of special and
complex rules apply in calculating this Section 382 limitation. While the complexity of Section 382 makes it difficult to determine whether and when an
ownership change has occurred, and if a portion of our NOLs is subject to an annual limitation under Section 382, we believe that an additional ownership
change may have occurred upon the consummation of the transaction with Curetis. In addition, our ability to use our NOL carryforwards will be limited to
the  extent  we  fail  to  generate  enough  taxable  income  in  the  future  before  they  expire.  Existing  and  future  Section  382  limitations  and  our  inability  to
generate enough taxable income in the future could result in a substantial portion of our NOL carryforwards expiring before they are used. In addition,
under the 2017 Tax Cut and Jobs Act, effective for losses arising in taxable years beginning after December 31, 2017, the deduction for NOLs is limited to
80% of taxable income, NOLs can no longer be carried back, and NOLs can be carried forward indefinitely.

33 

 
 
 
 
 
Our products and services may never achieve significant commercial market acceptance.

Our products and services may never gain significant acceptance in the marketplace and, therefore, may never generate substantial revenue or profits for us.
Our ability to achieve commercial market acceptance for our products will depend on several factors, including:

·

·

·

·

·

·

our ability to convince the medical community of the clinical utility of our products and services and their potential advantages over existing tests,
including our surveillance services offering, despite the lack of reimbursement for such services;

our  ability  to  successfully  develop  automated  rapid  pathogen  identification  and  antibiotic  resistance  testing  products  and  services,  including
bioinformatics, and convince hospitals and other healthcare providers of the patient safety, improved patient outcomes and potential cost savings
that could result;

our ability to grow our microbial isolate and antibiotic resistance genes knowledgebases and bioinformatics offerings;

our ability to convince the medical community of the accuracy and speed of our products and services, as contrasted with the current methods
available;

the willingness of hospitals and physicians to use our products and services; and

the ability of hospitals and labs to pay for our products and services.

Our future success is dependent upon our ability to expand our customer base.

The current customers we are targeting for our Unyvero and Acuitas test products and services are hospital systems, acute care hospitals, particularly those
with  advanced  care  units,  such  as  intensive  care  units,  community-based  hospitals  and  governmental  units,  such  as  public  health  facilities  and  other
laboratories. We need to provide a compelling case for the savings, patient safety and recovery, reduced length of stay and reduced costs that come from
adopting our MDRO diagnosis and antibiotic stewardship products and services. If we are not able to successfully increase our customer base, sales of our
products and our margins may not meet expectations. We are subject to similar challenges with respect to customers and partners for our ARESdb based
offerings and solutions. Attracting new customers and introducing new products and services requires substantial time and expense. Any failure to expand
our existing customer base, or launch new products and services, would adversely affect our ability to improve our operating results.

We are developing diagnostic products for the more rapid identification of MDROs and antibiotic resistance genomic information. If we are unable to
successfully  develop,  receive  regulatory  clearance  or  approval  for  or  commercialize  such  products  and  services,  our  business  will  be  materially,
adversely affected.

We are developing products that detect antibiotic resistance markers in under ninety minutes as well as four to five hours – and in the case of our NGS-
based  ARESupa  or  ARESiss  several  days  to  weeks  -  that  we  believe  could  help  address  many  of  the  current  issues  with  the  need  for  more  rapid
identification of infectious diseases and testing for antibiotic resistance. Development of such diagnostic products is difficult and we cannot assure you that
we will be successful in such product development efforts, or, if successful, that we will receive the necessary regulatory clearances to commercialize such
products. We have identified dozens of resistance genes to help guide clinicians with their antibiotic therapy decisions. Although we have demonstrated
preliminary feasibility, and confirmed genotype/phenotype predictive algorithms, such product development efforts will require us to work collaboratively
with  other  companies,  academic  and  government  laboratories,  and  healthcare  providers  to  access  sufficient  numbers  of  microbial  isolates,  develop  the
diagnostic tests, successfully conduct the necessary clinical trials and apply for and receive regulatory clearances or approvals for the intended use of such
diagnostic  tests.  In  addition,  we  would  need  to  successfully  commercialize  such  products.  Such  product  development,  clearance  or  approval  and
commercialization activities are time-consuming, expensive and we are not assured that we will have sufficient funds to successfully complete such efforts.
Any significant delays or failures in this process could have a material adverse effect on our business and financial condition.

We offer some of these products in development to the research use only market and for other non-clinical research uses prior to receiving clearance or
approval  to  commercialize  these  products  in  development  for  use  in  the  clinical  setting.  We  need  to  comply  with  the  applicable  laws  and  regulations
regarding such other uses. Failure to comply with such laws and regulations may have a significant impact on the Company.

34 

 
 
 
We may enter into agreements with U.S. or other government agencies, which could be subject to uncertain future funding.

The presence of MDROs and the need for antibiotic stewardship activities have prompted state, federal and international government agencies to develop
programs to combat the effects of MDROs. From 2018 through September 30, 2021, we were party to a collaboration, called the New York State Infectious
Disease  Digital  Health  Initiative,  with  the  New  York  State  DOH  and  ILÚM  (now  IDC)  to  develop  a  research  program  to  detect,  track,  and  manage
antimicrobial-resistant infections at healthcare institutions in New York State.

In the future, we may seek to enter into additional agreements with governmental funding sources or contract with government healthcare organizations to
sell our products and services. Under such agreements, we would rely on the continued performance by these government agencies of their responsibilities
under these agreements, including adequate continued funding of the agencies and their programs. We have no control over the resources and funding that
government agencies may devote to these agreements, which may be subject to annual renewal.

Government  agencies  may  fail  to  perform  their  responsibilities  under  these  agreements,  which  may  cause  them  to  be  terminated  by  the  government
agencies. In addition, we may fail to perform our responsibilities under these agreements. Any government agreements would be subject to audits, which
may occur several years after the period to which the audit relates. If an audit identified significant unallowable costs, we could incur a material charge to
our earnings or reduction in our cash position. As a result, we may be unsuccessful entering, or ineligible to enter, into future government agreements.

If the utility of our current products and products in development is not supported by studies published in peer-reviewed medical publications, the rate
of adoption of our current and future products and services by clinicians and healthcare facilities may be negatively affected.

The results of several of our clinical and economic validation studies involving our products have been presented at major infectious disease and infection
control society meetings and some have been published in peer reviewed scientific journals. We need to maintain and grow a continued presence in peer-
reviewed publications to promote clinician adoption of our products. We believe that peer-reviewed journal articles that provide evidence of the utility of
our current and future products and services, and adoption by key opinion leaders in the infectious disease market are very important to our commercial
success. Clinicians typically take a significant amount of time to adopt new products and testing practices, partly because of perceived liability risks and the
uncertainty  of  a  favorable  cost/benefit  analysis.  It  is  critical  to  the  success  of  our  sales  efforts  that  we  educate  a  sufficient  number  of  clinicians  and
administrators about our products and demonstrate their clinical benefits. Clinicians may not adopt our current and future products and services unless they
determine, based on published peer- reviewed journal articles and the experience of other clinicians, that our products provide accurate, reliable, useful and
cost-effective  information  that  is  useful  in  pathogen  identification  as  well  as  AMR  marker  detection  and  possibly  MDRO  diagnosis  and  outbreak
prevention. If our current and future products and services or the technology underlying our products and services or our future product offerings do not
receive sufficient favorable exposure in peer-reviewed publications, the rate of clinician adoption could be negatively affected. The publication of clinical
data in peer-reviewed journals is a crucial step in commercializing our products, and our inability to control when, if ever, results are published may delay
or limit our ability to derive sufficient revenue from any product that is the subject of a study.

Our sales cycle for our marketed products and services is lengthy and variable, which makes it difficult for us to forecast revenue and other operating
results.

The sales cycles for our products are lengthy, which will make it difficult for us to accurately forecast revenues in a given period, and may cause revenue
and  operating  results  to  vary  significantly  from  period  to  period.  Potential  customers  for  our  products  typically  need  to  commit  significant  time  and
resources to evaluate our products, and their decision to purchase our products may be further limited by budgetary constraints and numerous layers of
internal review and approval, which are beyond our control. We spend substantial time and effort assisting potential customers in evaluating our products.
Even  after  initial  approval  by  appropriate  decision  makers,  the  negotiation  and  documentation  processes  for  the  actual  adoption  of  our  products  on  a
facility-wide  basis  can  be  lengthy.  As  a  result  of  these  factors,  based  on  our  experience  to  date,  our  sales  cycle,  the  time  from  initial  contact  with  a
prospective  customer  to  routine  commercial  use  of  our  products,  has  varied  and  could  be  12  months  or  longer,  which  has  made  it  difficult  for  us  to
accurately project revenues and operating results. In addition, the revenue generated from sales of our products may fluctuate from time to time due to
changes in the testing volumes of our customers. As a result, our results may fluctuate on a quarterly basis, which may adversely affect the price of our
common stock.

35 

 
 
We  are  currently  party  to,  and  may  enter  into  additional  collaborations  with  third  parties  to  develop  product  and  services  candidates.  If  these
collaborations are not successful, our business could be adversely affected.

We are currently party to a few collaborations and anticipate that we will enter into additional collaborations related to our platforms and product offerings,
including  our  bioinformatics  products  and  services.  Such  collaborations  are  and  may  be  with  microbiology  and  IVD  companies,  pharmaceutical  and
biotech companies, CROs and CLIA labs, platform companies or other participants in our industry. We have limited control over the amount and timing of
resources that any such collaborators could dedicate to the development or commercialization of the subject matter of any such collaboration. Our ability to
generate revenues from these arrangements would depend on our and our collaborator’s abilities to successfully perform the functions assigned to each of
us in these arrangements. Our relationships with collaborators may pose several risks, including the following:

·

·

·

·

·

·

·

·

·

·

·

·

·

·

collaborators have significant discretion in determining the efforts and resources that they will apply to these collaborations;

collaborators may not perform their obligations as expected;

we may not achieve any milestones, or receive any milestone payments, under our collaborations, including milestones and/or payments that we
expect to achieve or receive;

the clinical trials, if any, conducted as part of these collaborations may not be successful;

a  collaborator  might  elect  not  to  continue  or  renew  development  or  commercialization  programs  based  on  clinical  trial  results,  changes  in  the
collaborator’s strategic focus or available funding or external factors, such as an acquisition, that diverts resources or creates competing priorities;

we may not have access to, or may be restricted from disclosing, certain information regarding the identity of the partner, financial details as well
as details on product or services candidates being developed or commercialized under a collaboration and, consequently, may have limited ability
to inform our stockholders about the status of such product or services candidates;

collaborators could independently develop, or develop with third parties, products that compete directly or indirectly with our product candidates
if the collaborators believe that competitive products are more likely to be successfully developed or can be commercialized under terms that are
more economically attractive than ours;

product or services candidates developed in collaboration with us may be viewed by our collaborators as competitive with their own product or
services, which may cause collaborators to cease to devote resources to the commercialization of our product or services candidates;

a collaborator with marketing and distribution rights to one or more of our product or services candidates that achieve regulatory approval may not
commit sufficient resources to the marketing and distribution of any such product candidate;

disagreements with collaborators, including disagreements over proprietary rights, contract interpretation or the preferred course of development
of  any  product  or  services  candidates,  may  cause  delays  or  termination  of  the  research,  development  or  commercialization  of  such  product  or
services candidates, may lead to additional responsibilities for us with respect to such product or services candidates or may result in litigation or
arbitration, any of which would be time-consuming and expensive;

collaborators  may  not  properly  maintain  or  defend  our  intellectual  property  rights  or  may  use  our  proprietary  information  in  such  a  way  as  to
invite litigation that could jeopardize or invalidate our intellectual property or proprietary information or expose us to potential litigation;

disputes may arise with respect to the ownership of intellectual property developed pursuant to a collaboration;

collaborators may infringe the intellectual property rights of third parties, which may expose us to litigation and potential liability; and

collaborations may be terminated for the convenience of the collaborator and, if terminated, we could be required to raise additional capital to
pursue further development or commercialization of the applicable product or services candidates.

If our collaborations do not result in the successful development and commercialization of products or services, we may not receive any future research
funding  or  milestone  or  royalty  payments  under  the  collaborations.  If  we  do  not  receive  the  funding  we  would  expect  under  these  agreements,  our
development of product and services candidates could be delayed, and we may need additional resources to develop our product candidates.

We may not be successful in finding strategic collaborators for continuing development of certain of our product or services candidates or successfully
commercializing or competing in the market for certain indications.

We may seek to develop strategic partnerships for developing certain of our product or services candidates, due to capital costs required to develop the
product  or  services  candidates  or  manufacturing  constraints.  We  may  not  be  successful  in  our  efforts  to  establish  such  a  strategic  partnership  or  other
alternative arrangements for our product or services candidates because our research and development pipeline may be insufficient, our product or services
candidates  may  be  deemed  to  be  at  too  early  of  a  stage  of  development  for  collaborative  effort  or  third  parties  may  not  view  our  product  or  services
candidates as having the requisite potential to demonstrate commercial success.

If we are unable to reach agreements with suitable collaborators on a timely basis, on acceptable terms or at all, we may have to curtail the development of
a  product  or  service  candidate,  reduce  or  delay  our  development  program,  delay  our  potential  commercialization,  reduce  the  scope  of  any  sales  or
marketing  activities  or  increase  our  expenditures  and  undertake  development  or  commercialization  activities  at  our  own  expense.  If  we  elect  to  fund
development or commercialization activities on our own, we may need to obtain additional expertise and additional capital, which may not be available to
us on acceptable terms or at all. If we fail to enter into collaborations and do not have sufficient funds or expertise to undertake the necessary development
and commercialization activities, we may not be able to further develop our product candidates and our business, financial condition, results of operations
and prospects may be materially and adversely affected.

We are an early commercial stage company and may never be profitable.

We rely principally on the commercialization of our Unyvero, ARESdb based, and Acuitas products and services to generate future revenue growth. To
date,  our  products  have  delivered  only  minimal  revenue.  We  believe  that  our  commercialization  success  is  dependent  upon  our  ability  to  significantly
increase the number of hospitals, labs, long-term care facilities and other inpatient healthcare settings that use our products. If demand for products does not
increase as quickly as we have planned, we may be unable to increase our revenue levels as expected. We are currently not profitable. Even if we succeed
in increasing adoption of our products by our target markets, maintaining and creating relationships with our existing and new customers and developing
and commercializing additional molecular testing products, we may not be able to generate sufficient revenue to achieve or sustain profitability.

We have limited experience in marketing and selling our products, and if we are unable to adequately address our customers’ needs, it could negatively
impact sales and market acceptance of our products and we may never generate sufficient revenue to achieve or sustain profitability.

We sell our products through our own direct sales force, which sells our products in the U.S. and via distribution partners in all other territories. All of these
products and services may be offered and sold to different potential customers or involve discussions with multiple stakeholders in inpatient facilities. Our
future sales will depend in large part on our ability to increase our marketing efforts and adequately address our customers’ needs. The inpatient healthcare
industry is a large and diverse market. We will need to attract and develop sales and marketing personnel with industry expertise. Competition for such
employees is intense. We may not be able to attract and retain sufficient personnel to maintain an effective sales and marketing force. If we are unable to
successfully market our products and adequately address our customers’ needs, it could negatively impact sales and market acceptance of our products and
we may never generate sufficient revenue to achieve or sustain profitability.

If our manufacturing facilities become inoperable, our products, and our business will be harmed.

We  manufacture  our  Unyvero  products  and  SARS-CoV-2  test  kits  in  our  facility  in  Bodelshausen,  Germany  and  our  Acuitas  products  in  our  facility  in
Rockville, Maryland, which we plan to move to the Bodelshausen facility in 2022. We do not have redundant facilities for these products. Our facilities and
the equipment we use to manufacture our products would be costly to replace and could require substantial lead time to repair or replace, if damaged or
destroyed. The facilities may be harmed or rendered inoperable by natural or man-made disasters, including flooding and power outages or fire, which may
render it difficult or impossible for us manufacture our products for some period of time. The inability to manufacture our products may result in the loss of
customers or harm our reputation, and we may be unable to regain those customers in the future. Although we carry insurance for damage to our property
and the disruption of our business, this insurance may not be sufficient to cover all of our potential losses and may not continue to be available to us on
acceptable terms, if at all.

In order to establish redundant facilities, we would have to spend considerable time and money securing adequate space, constructing the facility, recruiting
and training employees, and establishing the additional operational and administrative infrastructure necessary to support a second facility. Additionally,
any new manufacturing facility opened by us would be subject to FDA inspection and certification. If we fail to maintain our FDA certification or if our
FDA certification is suspended, limited or revoked, we would not be able manufacture our products.

If  demand  for  these  products  increase  beyond  our  current  forecasts  or,  regulatory  requirements  arise,  we  may  not  be  able  to  meet  our  obligations  to
manufacture these products, and backlog or reduced demand for such products could occur. If any of these issues occur, it could have a material adverse
effect on our financial condition and results of operations.

37 

 
 
We  rely  on  a  limited  number  of  suppliers  or,  in  some  cases,  sole  suppliers,  for  some  of  our  materials  and  may  not  be  able  to  find  replacements  or
immediately transition to alternative suppliers.

We rely on several sole suppliers and manufacturers, including Zollner, Contexo, Scholz, Thermo Fisher Scientific and Qiagen, for supplying instrument
systems and certain reagents, raw materials, supplies and substances which we use to manufacture our products. An interruption in our operations could
occur if we encounter delays or difficulties in securing these items or manufacturing our products, and if we cannot, then obtain an acceptable substitute.
Any such interruption or damage to third party suppliers or manufacturers for any reason, such as fire or other events beyond our control, including as a
result of natural disasters, terrorist attacks, or the occurrence of a contagious disease or illness, such as the COVID-19 pandemic, could significantly affect
our business, financial condition, results of operations and reputation.

Our distributors, collaboration partner, and service providers may be impacted and could be delayed or suspended as a result of the military action by
Russia in Ukraine.

We have distribution relationships with partners for the distribution of certain of our products in Russia and Ukraine as well as other neighboring territories.
We also have relationships with other parties and service providers that may operate in or be impacted by conditions in Russia and Ukraine.

In  February  2022,  Russia  commenced  a  military  invasion  of  Ukraine.  Russia’s  invasion  and  the  ensuing  response  by  Ukraine  may  disrupt  our  and  our
distribution partner’s distribution efforts in such jurisdictions, impact the ability of certain service providers to perform and could increase our costs and
disrupt future planned activities. For example, we believe our distribution partner will not be able to successfully distribute products in Ukraine or Russia
during the conflict and Curetis has suspended its business support to our distributors and will not accept any purchase orders until the geopolitical situation
has been resolved. Such disruption would significantly impact our ability to market, sell and distribute in such territories and could impact our ability to do
so in nearby territories, which would increase our costs and slow down and jeopardize our commercialization efforts.

If we cannot compete successfully with our competitors, we may be unable to increase or sustain our revenue or achieve and sustain profitability.

Our competitors include rapid diagnostic testing and traditional microbiology companies, commercial laboratories, information technology companies, and
hospital laboratories who may internally develop testing capabilities. Principal competitive factors in our target market include organizational size, scale,
and breadth of product offerings; rapidity of test results; quality and strength of clinical and analytical validation data and confidence in diagnostic results;
cost effectiveness; ease of use; and regulatory approval status.

Our  principal  competition  comes  from  traditional  methods  used  by  healthcare  providers  to  diagnose  and  screen  for  MDROs  and  from  other  molecular
diagnostic companies creating screening and diagnostic products such as Bosch, Cepheid (a Danaher company), Becton-Dickinson, bioMérieux, Accelerate
Diagnostics, T2 Biosystems, GenMark (a Roche company), Qiagen, Mobidiag (a Hologic company) and Luminex (a DiaSorin company).

We  also  face  competition  from  commercial  laboratories,  such  as  Bio-Reference  Laboratories,  Inc.,  Laboratory  Corporation  of  America  Holdings,  Quest
Diagnostics Incorporated, Pathnostics, and EuroFins, which have strong infrastructure to support the commercialization of diagnostic laboratory services.

Competitors may develop their own versions of competing products in countries where we do not have patents or where our intellectual property rights are
not recognized.

Many of our potential competitors have widespread brand recognition and substantially greater financial, technical, research and development and selling
and marketing capabilities than we do. Others may develop products with prices lower than ours that could be viewed by hospitals, physicians and payers
as functionally equivalent to our product and service offering or offer products at prices designed to promote market penetration, which could force us to
lower  the  list  prices  of  our  product  and  service  offerings  and  affect  our  ability  to  achieve  profitability.  If  we  are  unable  to  change  clinical  practice  in  a
meaningful way or compete successfully against current and future competitors, we may be unable to increase market acceptance and sales of our products,
which could prevent us from increasing our revenue or achieving profitability and could cause our stock price to decline.

Our  products  and  services  are  not  covered  by  reimbursement  by  Medicare,  Medicaid  and  other  governmental  and  third-party  payors.  If  we  cannot
convince our customers that the savings from use of our products and services will increase their overall reimbursement, our business could suffer.

Our products and services do not currently receive reimbursement from Medicare, Medicaid, other governmental payors or commercial third-party payors.
Policy and rule changes in reimbursement announced by CMS, including potential financial incentives for reductions in hospital acquired infection, and
penalties and decreased Medicare reimbursement for patients with HAIs provide us with an opportunity to establish a business case for the purchase and
use of our screening and diagnostic products and services. If we cannot convince our customers that the savings from use of our products and services will
increase or stabilize their overall profitability and improve clinical outcomes, our business will suffer.

Failure in our information technology, storage systems or our ares-genetics.cloud services could significantly disrupt our operations and our research
and development efforts, which could adversely impact our revenues, as well as our research, development and commercialization efforts.

Our  ability  to  execute  our  business  strategy  depends,  in  part,  on  the  continued  and  uninterrupted  performance  of  our  information  technology  systems,
which support our operations and our research and development efforts, as well as our storage systems and our analyzers. Due to the sophisticated nature of
the technology we use in our products and service offerings, including our ARESdb and ares-genetics.cloud services, we are substantially dependent on our
information  technology  systems.  Information  technology  systems  are  vulnerable  to  damage  from  a  variety  of  sources,  including  telecommunications  or
network failures, malicious human acts and natural disasters. Moreover, despite network security and back-up measures, some of our servers are potentially
vulnerable  to  physical  or  electronic  break-ins,  computer  viruses  and  similar  disruptive  problems.  Despite  the  precautionary  measures  we  have  taken  to
prevent  unanticipated  problems  that  could  affect  our  information  technology  systems,  sustained  or  repeated  system  failures  that  interrupt  our  ability  to
generate and maintain data, and in particular to operate our ARESdb, could adversely affect our ability to operate our business. Any interruption in the
operation of our ARESdb, due to information technology system failures, part failures or potential disruptions in the event we are required to relocate our
instruments within our facility or to another facility, could have an adverse effect on our operations.

Security  breaches,  loss  of  data  and  other  disruptions  could  compromise  sensitive  information  related  to  our  business  or  prevent  us  from  accessing
critical information and expose us to liability, which could adversely affect our business and our reputation.

In  the  ordinary  course  of  our  business,  we  collect  and  store  sensitive  data,  which  may  include  legally  protected  health  information  and  personally
identifiable  information  about  our  customers  and  their  patients.  We  also  store  sensitive  intellectual  property  and  other  proprietary  business  information,
including that of our customers. We manage and maintain our applications and data utilizing a combination of on-site systems and cloud-based data center
systems.  These  applications  and  data  encompass  a  wide  variety  of  business-critical  information,  including  research  and  development  information,
commercial information and business and financial information.

We face four primary risks relative to protecting this critical information: loss of access risk, inappropriate disclosure risk, inappropriate modification risk
and the risk of our being unable to identify and audit our controls over the first three risks.

We  are  highly  dependent  on  information  technology  networks  and  systems,  including  the  Internet,  to  securely  process,  transmit  and  store  this  critical
information. Security breaches of this infrastructure, including physical or electronic break-ins, computer viruses, phishing attempts, attacks by hackers and
similar breaches, can create system disruptions, shutdowns or unauthorized disclosure or modification of confidential information. The secure processing,
storage, maintenance, and transmission of this critical information is vital to our operations and business strategy, and we devote significant resources to
protecting  such  information.  Although  we  take  measures  to  protect  sensitive  information  from  unauthorized  access  or  disclosure,  our  information
technology and infrastructure may be vulnerable to attacks by hackers or viruses or breached due to employee error, malfeasance or other disruptions.

A  security  breach  or  privacy  violation  that  leads  to  disclosure  or  modification  of  or  prevents  access  to  consumer  information  (including  personally
identifiable  information  or  protected  health  information)  could  harm  our  reputation,  compel  us  to  comply  with  disparate  state  breach  notification  laws,
require us to verify the correctness of database contents and otherwise subject us to liability under laws that protect personal data, resulting in increased
costs  or  loss  of  revenue.  If  we  are  unable  to  prevent  such  security  breaches  or  privacy  violations  or  implement  satisfactory  remedial  measures,  our
operations  could  be  disrupted,  and  we  may  suffer  loss  of  reputation,  financial  loss  and  other  regulatory  penalties  because  of  lost  or  misappropriated
information,  including  sensitive  consumer  data.  In  addition,  these  breaches  and  other  inappropriate  access  can  be  difficult  to  detect,  and  any  delay  in
identifying them may lead to increased harm of the type described above.

39 

 
 
Any  such  breach  or  interruption  could  compromise  our  networks,  and  the  information  stored  there  could  be  inaccessible  or  could  be  accessed  by
unauthorized parties, publicly disclosed, lost or stolen. Any such interruption in access, improper access, disclosure or other loss of information could result
in legal claims or proceedings, liability under laws that protect the privacy of personal information, such as the federal HIPAA and regulatory penalties.
Unauthorized access, loss or dissemination could also disrupt our operations, including our ability to perform tests, provide test results, bill facilities or
patients,  process  claims  and  appeals,  provide  customer  assistance  services,  conduct  research  and  development  activities,  collect,  process  and  prepare
Company financial information, provide information about our current and future solutions and other patient and clinician education and outreach efforts
through our website, and manage the administrative aspects of our business and damage our reputation, any of which could adversely affect our business.
Any such breach could also result in the compromise of our trade secrets and other proprietary information, which could adversely affect our competitive
position.

In addition, the interpretation and application of consumer, health-related, privacy and data protection laws in the U.S. and elsewhere are often uncertain,
contradictory and in flux. It is possible that these laws may be interpreted and applied in a manner that is inconsistent with our practices. If so, this could
result  in  government-imposed  fines  or  orders  requiring  that  we  change  our  practices,  which  could  adversely  affect  our  business.  Complying  with  these
various laws could cause us to incur substantial costs or require us to change our business practices and compliance procedures in a manner adverse to our
business.

Data collection is governed by restrictive regulations governing the use, processing, and cross-border transfer of personal information.

The collection, use, storage, transfer, and other processing of personal data, including personal health data, regarding individuals in the European Economic
Area  is  governed,  as  of  May  2018,  by  the  General  Data  Protection  Regulation,  or  GDPR.  The  GDPR  imposes  several  requirements  on  companies  that
process  personal  data,  including  requirements  relating  to  the  processing  of  health  and  other  sensitive  data,  the  consent  of  the  individuals  to  whom  the
personal data relates, the information provided to the individuals regarding data processing activities, the notification of data processing obligations to the
competent national data protection authorities and certain measures to be taken when engaging third-party data processors. The GDPR also imposes strict
rules on the transfer of personal data out of the European Economic Area, including to the U.S. Failure to comply with the requirements of the GDPR, and
the  related  national  data  protection  laws  of  the  European  Union  Member  States,  may  result  in  fines  and  other  administrative  penalties.  The  GDPR  also
confers a private right of action on data subjects and consumer associations to lodge complaints with supervisory authorities, seek judicial remedies, and
obtain  compensation  for  damages  resulting  from  violations  of  the  GDPR.  The  GDPR  regulations  may  impose  additional  responsibility  and  liability  in
relation to personal data that we process, and we may be required to put in place additional mechanisms ensuring compliance with the new data protection
rules, including as implemented by individual countries. This may be onerous and adversely affect our business, financial condition, results of operations
and prospects. Compliance with the GDPR is a rigorous and time-intensive process that may increase our cost of doing business or require us to change our
business practices, and despite those efforts, there is a risk that we may be subject to fines and penalties, litigation, and reputational harm in connection
with any future European activities.

California  recently  enacted  the  California  Consumer  Privacy  Act,  or  CCPA,  which  creates  new  individual  privacy  rights  for  California  consumers  (as
defined  in  the  law)  and  places  increased  privacy  and  security  obligations  on  entities  handling  personal  data  of  consumers  or  households.  The  CCPA
requires  covered  companies  to  provide  certain  disclosures  to  consumers  about  its  data  collection,  use  and  sharing  practices,  and  to  provide  affected
California  residents  with  ways  to  opt-out  of  certain  sales  or  transfers  of  personal  information.  The  CCPA  went  into  effect  on  January  1,  2020,  and  the
California Attorney General commenced enforcement actions against violators on July 1, 2020. While there is currently an exception for protected health
information  that  is  subject  to  HIPAA,  and  clinical  trial  regulations,  as  currently  written,  the  CCPA  may  impact  our  business  activities.  The  California
Attorney General has proposed draft regulations, which have not been finalized to date, that may further impact our business activities if they are adopted.
The uncertainty surrounding the implementation of the CCPA exemplifies the vulnerability of our business to the evolving regulatory environment related
to personal data and protected health information.

We cannot provide assurance that future legislation will not prevent us from generating or maintaining personal data or that patients will consent to the use
of their personal information, either of which may prevent us from undertaking or publishing essential research. These burdens or risks may prove too great
for us to reasonably bear and may adversely affect our ability to achieve profitability or maintain profitably in the future.

40 

 
 
If  we  are  unable  to  develop  products  to  keep  pace  with  rapid  technological,  medical  and  scientific  change,  our  operating  results  and  competitive
position could be harmed. New test development involves a lengthy and complex process, and we may not be successful in our efforts to develop and
commercialize  our  diagnostic  and  screening  products  and  services.  The  further  development  and  commercialization  of  additional  diagnostic  and
screening product and service offering are key to our growth strategy.

A  key  element  of  our  strategy  is  to  discover,  develop,  validate  and  commercialize  a  portfolio  of  additional  diagnostic  products  and  services  to  rapidly
diagnose  pathogens  and  AMR  and  effectively  treat  MDRO  infections  and  reduce  the  associated  costs  to  patients,  inpatient  facilities  and  the  healthcare
industry. We cannot assure you that we will be able to successfully complete development of or commercialize any of our planned future products and
services, or that they will be clinically usable. The product development process involves a high degree of risk and may take up to several years or longer.
Our new product development efforts may fail for many reasons, including:

·

·

·

·

·

failure of the tests at the research or development stage;

lack of clinical validation data to support the effectiveness of the tests;

delays resulting from the failure of third-party suppliers or contractors to meet their obligations in a timely and cost-effective manner;

failure to obtain or maintain necessary certifications, licenses, clearances or approvals to market or perform the test; or

lack of commercial acceptance by inpatient healthcare facilities and commercial partners.

Few research and development projects result in commercial products, and success in early clinical studies often is not replicated in later studies. At any
point, we may abandon development of new products, or we may be required to expend considerable resources repeating clinical studies or trials, which
would adversely impact the timing for generating potential revenues from those new products. In addition, as we develop new products, we will have to
make  additional  investments  in  our  sales  and  marketing  operations,  which  may  be  prematurely  or  unnecessarily  incurred  if  the  commercial  launch  of  a
product is abandoned or delayed.

If we use hazardous materials in a manner that causes injury, we could be liable for damages.

Our activities currently require the use of hazardous materials and the handling of patient samples. We cannot eliminate the risk of accidental contamination
or injury to employees or third parties from the use, storage, handling or disposal of these materials. In the event of contamination or injury, we could be
held liable for any resulting damages, and any liability could exceed our resources or any applicable insurance coverage we may have. Additionally, we are
subject  on  an  ongoing  basis  to  federal,  state  and  local  laws  and  regulations  governing  the  use,  storage,  handling  and  disposal  of  these  materials  and
specified  waste  products.  We  are,  or  may  be  in  the  future,  subject  to  compliance  with  additional  laws  and  regulations  relating  to  the  protection  of  the
environment and human health and safety, and including those relating to the handling, transportation and disposal of medical specimens, infectious and
hazardous waste and Occupational Safety and Health Administration, or OSHA, requirements as well as their international equivalents. The requirements
of  these  laws  and  regulations  are  complex,  change  frequently  and  could  become  more  stringent  in  the  future.  Failure  to  comply  with  current  or  future
environmental  laws  and  regulations  could  result  in  the  imposition  of  substantial  fines,  suspension  of  production,  alteration  of  our  production  processes,
cessation of operations or other actions, which could severely harm our business.

If we are sued for product liability or errors and omissions liability, we could face substantial liabilities that exceed our resources.

The  marketing,  sale  and  use  of  our  products  could  lead  to  product  liability  claims  if  someone  were  to  allege  that  a  product  failed  to  perform  as  it  was
designed. We may also be subject to liability for errors in the results we provide to physicians or for a misunderstanding of, or inappropriate reliance upon,
the  information  we  provide.  For  example,  if  we  diagnosed  a  patient  as  having  an  MDRO  but  such  result  was  a  false  positive,  the  patient  could  be
unnecessarily isolated in an inpatient setting or receive inappropriate treatment. We may also be subject to similar types of claims related to products we
may develop in the future. A product liability or errors and omissions liability claim could result in substantial damages and be costly and time consuming
for us to defend. Although we maintain product liability and errors and omissions insurance, we cannot assure you that our insurance would fully protect us
from the financial impact of defending against these types of claims or any judgments, fines or settlement costs arising out of any such claims. Any product
liability or errors and omissions liability claim brought against us, with or without merit, could increase our insurance rates or prevent us from securing
insurance coverage in the future. Additionally, any product liability lawsuit could cause injury to our reputation or cause us to suspend sales of our products
and services. The occurrence of any of these events could have an adverse effect on our business and results of operations.

Risks Related to Our Securities and Public Company Status

We received a bid price deficiency notice from the Nasdaq Capital Market. If we are unable to cure this deficiency and meet the NASDAQ continued
listing requirements, we could be delisted from the Nasdaq Capital Market, which would negatively impact the trading of our common stock.

On February 28, 2022, we received notice from Nasdaq that we had failed to maintain a bid price of at least $1.00 per share for 30 successive trading days.
We  have  six  months  to  regain  compliance  with  the  listing  standard.  We  are  currently  considering  our  alternatives  to  restore  the  bid  price,  including  a
reverse stock split of our common stock. However, there can be no assurance that we will be able to maintain the Nasdaq Capital Market listing of our
common stock in the future.

If our common stock is delisted by Nasdaq, our common stock may be eligible for quotation on an over-the-counter quotation system or on the pink sheets.
Upon any such delisting, our common stock would become subject to the regulations of the SEC relating to the market for penny stocks. A penny stock is
any equity security not traded on a national securities exchange that has a market price of less than $5.00 per share. The regulations applicable to penny
stocks may severely affect the market liquidity for our common stock and could limit the ability of stockholders to sell securities in the secondary market.
In such a case, an investor may find it more difficult to dispose of or obtain accurate quotations as to the market value of our common stock, and there can
be no assurance that our common stock will be eligible for trading or quotation on any alternative exchanges or markets.

Delisting  from  Nasdaq  could  adversely  affect  our  ability  to  raise  additional  financing  through  public  or  private  sales  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 could
also  have  other  negative  results,  including  the  potential  loss  of  confidence  by  employees,  the  loss  of  institutional  investor  interest  and  fewer  business
development opportunities.

If we are unable to maintain effective internal control over financial reporting, investors may lose confidence in the accuracy and completeness of our
reported financial information and the market price of our common stock may be negatively affected.

As a public company, we are required to maintain internal control over financial reporting and to report any material weaknesses in such internal control.
Section 404 of the Sarbanes-Oxley Act of 2002 requires that we evaluate and determine the effectiveness of our internal control over financial reporting
and  provide  a  management  report  on  internal  control  over  financial  reporting.  If  we  have  a  material  weakness  in  our  internal  control  over  financial
reporting, we may not detect errors on a timely basis and our financial statements may be materially misstated.

When we are no longer a smaller reporting company, our independent registered public accounting firm will be required to issue an attestation report on the
effectiveness  of  our  internal  control  over  financial  reporting.  Even  if  our  management  concludes  that  our  internal  control  over  financial  reporting  is
effective, our independent registered public accounting firm may conclude that there are material weaknesses with respect to our internal controls or the
level at which our internal controls are documented, designed, implemented or reviewed.

When we are no longer a smaller reporting company, if our auditors were to express an adverse opinion on the effectiveness of our internal control over
financial reporting because we had one or more material weaknesses, investors could lose confidence in the accuracy and completeness of our financial
disclosures, which could cause the price of our common stock to decline. Internal control deficiencies could also result in a restatement of our financial
results in the future.

The  market  price  of  our  common  stock  has  been,  and  may  continue  to  be,  highly  volatile,  and  such  volatility  could  cause  the  market  price  of  our
common stock to decrease and could cause you to lose some or all of your investment in our common stock.

During the period from our initial public offering in May 2015 through December 31, 2021, the market price of our common stock fluctuated from a high
of $2,720.00 per share to a low of $0.92 per share, and our stock price continues to fluctuate. The market price of our common stock may continue to
fluctuate significantly in response to numerous factors, some of which are beyond our control, such as:

·

·

·

·

our ability to grow our revenue and customer base;

the announcement of new products or product enhancements by us or our competitors;

the market entry of new competitors;

developments concerning regulatory oversight and approvals;

42 

 
 
 
·

·

·

·

·

·

·

·

·

variations in our and our competitors’ results of operations;

changes in earnings estimates or recommendations by securities analysts, if our common stock is covered by analysts;

successes or challenges in our collaborative arrangements or alternative funding sources;

developments in the health care and life science industries;

the results of product liability or intellectual property lawsuits;

future issuances of common stock or other securities;

the addition or departure of key personnel;

announcements by us or our competitors of acquisitions, investments or strategic alliances; and

general market conditions and other factors, including factors unrelated to our operating performance and/or unrelated to our industry.

Further, the stock market in general, and the market for health care and life science companies in particular, has recently experienced extreme price and
volume fluctuations. Continued market fluctuations could result in extreme volatility in the price of our common stock, which could cause a decline in the
value of our common stock and the loss of some or all of your investment.

The exercise of outstanding common stock purchase warrants and stock options will have a dilutive effect on the percentage ownership of our capital
stock by existing stockholders.

As of December 31, 2021, we had outstanding warrants to acquire 16,217,946 shares of our common stock, and stock options to purchase 1,713,349 shares
of our common stock. The expiration of the term of such options and warrants range from June 2022 to July 2031. A significant number of such warrants
are out of the money, but the holders have the right to affect a cashless exercise of such warrants. If a significant number of such warrants and stock options
are exercised by the holders, the percentage of our common stock owned by our existing stockholders will be diluted.

Unstable market and economic conditions may have serious adverse consequences on our business, financial condition and stock price. 

The  global  credit  and  financial  markets  have  recently  experienced  extreme  volatility  and  disruptions,  including  severely  diminished  liquidity  and  credit
availability, declines in consumer confidence, declines in economic growth, instability in inflation in U.S. and foreign markets, increases in unemployment
rates and uncertainty about economic stability. The financial markets and the global economy may also be adversely affected by the current or anticipated
impact  of  military  conflict,  including  the  conflict  between  Russia  and  Ukraine,  terrorism  or  other  geopolitical  events.  Sanctions  imposed  by  the  United
States  and  other  countries  in  response  to  such  conflicts,  including  the  one  in  Ukraine,  may  also  adversely  impact  the  financial  markets  and  the  global
economy,  and  any  economic  countermeasures  by  affected  countries  and  others  could  exacerbate  market  and  economic  instability.  There  can  be  no
assurance that further deterioration in credit and financial markets and confidence in economic conditions will not occur. Our general business strategy may
be adversely affected by any such economic downturn, volatile business environment or continued unpredictable and unstable market conditions, including
instability in inflation. If the current equity and credit markets deteriorate, it may make any necessary debt or equity financing more difficult, more costly
and more dilutive. Failure to secure any necessary financing in a timely manner and on favorable terms could have a material adverse effect on our growth
strategy, financial performance and stock price and could require us to delay or abandon clinical development plans. In addition, there is a risk that one or
more of our current service providers, distributors, manufacturers, and other partners may not survive an economic downturn or could be adversely affected
by geopolitical events, such as the conflict in Ukraine, which could directly affect our ability to attain our operating goals on schedule and on budget.

A large base of individual stockholders may make it difficult for us to take action on certain corporate transactions and matters, which may limit the
ability of the Company to enter into certain transaction. 

We  believe  that  we  currently  have  a  large  base  of  individual  stockholders  instead  of  institutional  investors.  Procuring  the  vote  of  such  stockholders  in
connection  with  certain  corporate  transactions  and  matters  is  difficult,  time  consuming  and  expensive.  For  example,  in  connection  with  the  Company’s
2021  Annual  Meeting  for  stockholders,  despite  extensive  efforts  by  the  Company,  we  were  unable  to  receive  votes  from  a  sufficient  portion  of  our
outstanding shares of common stock required to approve certain proposals submitted at such meeting, despite the fact that, of those shares that had voted on
the proposals, such shares had supported the approval of such proposals.

We  expect  that  we  may  continue  to  need  stockholder  approval  of  additional  matters  in  the  future,  including,  in  connection  with,  amendments  to  the
Company’s  amended  and  restated  certificate  of  incorporation,  as  amended,  and  for  certain  other  corporate  transactions.  If  we  are  unable  to  obtain  the
requisite vote due to stockholder disinterest and apathy for engaging in corporate governance of the Company, we may be unable to take certain actions,
which could prevent or limit our ability to further finance the Company in the future or enter into certain transactions.

43 

 
 
 
 
Short sellers of our stock may be manipulative and may drive down the market price of our common stock.

Short  selling  is  the  practice  of  selling  securities  that  a  seller  does  not  own  but  rather  has  borrowed,  or  intends  to  borrow,  from  a  third  party  with  the
intention  of  buying  identical  securities  at  a  later  date  to  return  to  the  lender.  A  short  seller  hopes  to  profit  from  a  decline  in  the  value  of  the  securities
between  the  sale  of  the  borrowed  securities  and  the  purchase  of  the  replacement  shares,  as  the  short  seller  expects  to  pay  less  in  that  purchase  than  it
received in the sale. As it is in the short seller’s interest for the price of the stock to decline, some short sellers publish, or arrange for the publication of,
opinions or characterizations regarding the relevant issuer, its business prospects and similar matters calculated to or which may create negative market
momentum, which may permit them to obtain profits for themselves as a result of selling the securities short. The use of the Internet, social media, and
blogging have allowed short sellers to publicly attack a company’s credibility, strategy and veracity by means of so-called “research reports” that mimic the
type  of  investment  analysis  performed  by  legitimate  securities  research  analysts.  Issuers  with  substantial  retail  stockholder  bases  can  be  particularly
susceptible to higher volatility levels, and can be particularly vulnerable to such short attacks.

While we intend to strongly defend our public filings against any such short seller attacks, in many situations we could be constrained, for example, by
principles of freedom of speech, applicable state law or issues of commercial confidentiality, in the manner in which we are able to proceed against the
relevant short seller. Such short-seller attacks may cause, temporary or possibly long term, declines in the market price of our common stock.

We  may  be  subject  to  litigation  or  government  investigations  for  a  variety  of  claims,  which  could  adversely  affect  our  operating  results,  harm  our
reputation or otherwise negatively impact our business.

We may be subject to litigation or government investigations. These may include claims, lawsuits, and proceedings involving securities laws, fraud and
abuse, healthcare compliance, product liability, labor and employment, wage and hour, commercial and other matters. Any such litigation or investigations
could  result  in  substantial  costs  and  a  diversion  of  management’s  resources  and  attention.  In  addition,  any  adverse  determination  could  expose  us  to
significant liabilities, which could have a material adverse effect on our business, financial condition, and results of operations.

Risks Related to Regulation of Our Business

There  is  no  guarantee  that  the  FDA  will  grant  De  Novo  classification  requests,  510(k)  clearance  or  PMA  approval  of  our  products,  and  failure  to
obtain necessary clearances or approvals for our future products would adversely affect our ability to grow our business.

We have received 510(k) clearance from the FDA for our Acuitas AMR Gene Panel test as well as FDA clearances for Unyvero LRT and LRT BAL in the
past. We have plans to submit additional De Novo classification requests for our Unyvero UTI test and our Unyvero IJI test in the future. Such process is
complex, time consuming and expensive. For any filed 510(k) or De Novo submission, the FDA may not clear or grant these products for the indications
that  are  necessary  or  desirable  for  successful  commercialization.  Failure  to  receive,  or  a  significant  delay  in  receiving,  a  required  clearance  or  granted
request for our products would have a material adverse effect on our ability to expand our business.

We may be subject to fines, penalties or injunctions if we are determined to be promoting the use of our products for unapproved or “off-label” uses.

We are currently offering for sale some RUO products to labs, CROs, diagnostics, pharmaceutical and biotech companies, hospitals and other healthcare
facilities. We believe that our promotional activities for these products falls within the scope of the FDA’s enforcement discretion and applicable premarket
exemptions. However, the FDA could disagree and require us to stop promoting our products for unapproved or “off-label” uses unless and until we obtain
FDA clearance or approval for those uses. We could be subject to regulatory or enforcement actions for any violations, including, but not limited to, the
issuance of an untitled letter, a Form 483 letter, a warning letter, injunction, seizure, civil fine and criminal penalties. It is also possible that other federal,
state or foreign enforcement authorities might take action if they consider our promotional materials to constitute promotion of an unapproved use, which
could result in significant fines or penalties under other statutory authorities, such as laws prohibiting false claims for reimbursement. In that event, our
reputation could be damaged, and adoption of the products would be impaired.

44 

 
 
 
A number of our rapid diagnostic products are regulated by the FDA and non-U.S. regulatory authorities. If we or our suppliers fail to comply with
ongoing FDA, or other foreign regulatory authority, requirements, or if we experience unanticipated problems with the products, these products could
be subject to restrictions or withdrawal from the market.

We  do  not  have  significant  experience  in  complying  with  the  rules  and  regulations  of  the  FDA  and  foreign  regulatory  authorities.  The  rapid  diagnostic
products regulated as medical devices, and the manufacturing processes, reporting requirements, post-approval clinical data and promotional activities for
such products, are subject to continued regulatory review, oversight and periodic inspections by the FDA and other domestic and foreign regulatory bodies.
In  particular,  we  and  our  suppliers  are  required  to  comply  with  FDA’s  QSR  regulations  for  the  manufacture,  labeling,  distribution  and  promotion  of
products  and  other  regulations  which  cover  the  methods  and  documentation  of  the  design,  testing,  production,  control,  quality  assurance,  labeling,
packaging,  storage  and  shipping  of  any  product  for  which  we  obtain  clearance  or  approval,  and  with  ISO  regulations.  The  FDA  enforces  the  QSR  and
similarly, other regulatory bodies with similar regulations enforce those regulations through periodic inspections. The failure by us or one of our suppliers
to comply with applicable statutes and regulations administered by the FDA and other regulatory bodies, or the failure to timely and adequately respond to
any adverse inspectional observations or product safety issues, could result in, among other things, any of the following enforcement actions against us: (1)
untitled letters, Form 483 observations, warning letters, fines, injunctions, consent decrees and civil penalties; (2) unanticipated expenditures to address or
defend such actions; (3) customer notifications for repair, replacement and refunds; (4) recall, detention or seizure of our products; (5) operating restrictions
or  partial  suspension  or  total  shutdown  of  production;  (6)  refusing  or  delaying  our  requests  for  De  Novo  classification,  510(k)  clearance  or  premarket
approval  of  new  products  or  modified  products;  (7)  operating  restrictions;  (8)  withdrawing  granted  De Novo  classifications,  510(k)  clearances  or  PMA
approvals that have already been granted; (9) refusal to grant export approval for our products; or (10) criminal prosecution.

If  any  of  these  actions  were  to  occur,  it  could  harm  our  reputation  and  cause  our  product  sales  and  profitability  to  suffer  and  may  prevent  us  from
generating  revenue.  Furthermore,  if  any  of  our  key  component  suppliers  are  not  in  compliance  with  all  applicable  regulatory  requirements,  we  may  be
unable to produce our products on a timely basis and in the required quantities, if at all.

We and our suppliers are also subject to periodic inspections by the FDA to determine compliance with the FDA’s requirements, including primarily the
QSR and medical device reporting regulations. The results of these inspections can include inspectional observations on FDA’s Form 483, untitled letters,
warning letters, or other forms of enforcement. Since 2009, the FDA has significantly increased its oversight of companies subject to its regulations, by
hiring new investigators and stepping up inspections of manufacturing facilities. The FDA has recently also significantly increased the number of warning
letters issued to companies. If the FDA were to conclude that we are not in compliance with applicable laws or regulations, or that any of our FDA-cleared
products are ineffective or pose an unreasonable health risk, the FDA could take a number of regulatory actions, including but not limited to, preventing us
from manufacturing any or all of our devices or performing laboratory testing on human specimens, which could materially adversely affect our business.

Some of the clearances obtained are subject to limitations on the intended uses for which the product may be marketed, which can reduce our potential to
successfully commercialize the product and generate revenue from the product. If the FDA determines that our promotional materials, labeling, training or
other marketing or educational activities constitute promotion of an unapproved use, it could request that we cease or modify our training or promotional
materials or subject us to regulatory enforcement actions. It is also possible that other federal, state or foreign enforcement authorities might take action if
they consider our training or other promotional materials to constitute promotion of an unapproved use, which could result in significant fines or penalties
under other statutory authorities, such as laws prohibiting false claims for reimbursement.

In addition, we may be required to conduct costly post-market testing and surveillance to monitor the safety or effectiveness of our products, and we must
comply with medical device reporting requirements, including the reporting of adverse events and malfunctions related to our products. Later discovery of
previously  unknown  problems  with  our  products,  including  unanticipated  adverse  events  or  adverse  events  of  unanticipated  severity  or  frequency,
manufacturing problems, or failure to comply with regulatory requirements such as QSR, may result in changes to labeling, restrictions on such products or
manufacturing processes, withdrawal of the products from the market, voluntary or mandatory recalls, a requirement to repair, replace or refund the cost of
any  medical  device  we  manufacture  or  distribute,  fines,  suspension  of  regulatory  approvals,  product  seizures,  injunctions  or  the  imposition  of  civil  or
criminal penalties which would adversely affect our business, operating results and prospects.

If we were to lose, or have restrictions imposed on, FDA clearances received to date, or clearances we may receive in the future, our business, operations,
financial condition and results of operations would likely be significantly adversely affected.

45 

 
 
Modifications to our marketed products may require new 510(k) clearances, De Novo classifications or PMA approvals or, in the future, new CE-IVD
markings  that  comply  with  the  new  IVDR,  or  may  require  us  to  cease  marketing  or  recall  the  modified  products  until  clearances  or  approvals  are
obtained.

If we modify any of our CE-IVD marked or FDA-cleared products, such modifications may require additional future approvals and filings, e.g., notified
body authorization or FDA clearance. Modifications to a CE-IVD marked or 510(k)-cleared device that could significantly affect its safety or effectiveness,
or that would constitute a major change in its intended use, may require additional approvals or filings or a new or revised 510(k) submission, or possibly, a
PMA or new IVDR compliant product authorization.

The  FDA  and  other  regulatory  authorities,  including  notified  bodies,  require  every  medical  device  manufacturer  to  make  this  determination,  with  the
potential for the regulatory authorities to impose additional requirements. The applicable regulatory authority nevertheless maintains the right to disagree
with a company’s decisions regarding whether new clearances or approvals are necessary. If the FDA or any other relevant regulatory authority requires us
to submit additional filings, such as a technical file review and CE-marking under new IVDR, 510(k) submission, or file a De Novo classification request
or a PMA, for any modification to a previously cleared product, we may be required to cease marketing and distributing, or to recall the modified product
until we obtain such clearance or approval, and we may be subject to significant regulatory fines or penalties. Furthermore, our products could be subject to
recall if the FDA or any other relevant regulatory authority determines, for any reason, that our products are not safe or effective. A mandate for a recall or
correction,  or  where  new  or  revised  regulatory  submissions  are  required,  could  result  in  significant  delays,  fines,  increased  costs  associated  with
modification of a product, loss of revenue and potential operating restrictions imposed by the FDA or other relevant regulatory agencies in other territories.

New or revised regulatory requirements may require us to cease marketing or recall the modified products until clearances or approvals are obtained.

In 2017, the EU Regulation on In Vitro Diagnostic Medical Devices (Regulation (EU) 2017/746) (“IVDR”) was adopted. The IVDR is expected to apply
commencing on May 26, 2022, subject to certain extended transition periods for existing CE-IVD marked products until the 2025 to 2027 time frame, and
is, among other things, intended to establish a uniform, transparent, predictable and sustainable regulatory framework across European Economic Area.
Once applicable, the IVDR will introduce new classification rules for in vitro diagnostic medical devices and new regulatory requirements. Moreover, the
scrutiny imposed by notified bodies for the technical documentation related these devices will increase considerably. Complying with the requirements of
this  regulation  may  result  in  the  reclassification  of  existing  CE-IVD  marked  product  and  require  additional  filings  with  the  notified  body  or  competent
authority. Additional filings and or modifications to products to comply with the IVDR could result in significant delays, increased costs associated with
modification of a product, loss of revenue and other significant expenditures.

Our products may in the future be subject to product recalls that could harm our reputation, business and financial results.

The FDA and similar foreign governmental authorities have the authority to require the recall of regulated products in the event of material deficiencies or
defects  in  design  or  manufacture.  In  the  case  of  the  FDA,  the  authority  to  require  a  recall  must  be  based  on  an  FDA  finding  that  there  is  a  reasonable
probability  that  the  device  would  cause  serious  injury  or  death.  In  addition,  foreign  governmental  bodies  have  the  authority  to  require  the  recall  of  our
products in the event of material deficiencies or defects in design or manufacture.

Manufacturers may, under their own initiative, recall a product if any material deficiency in a device is found. A government-mandated or voluntary recall
by us or one of our distributors could occur as a result of component failures, manufacturing errors, design or labeling defects or other deficiencies and
issues. Recalls of any of our products would divert managerial and financial resources and have an adverse effect on our financial condition and results of
operations. The FDA requires that certain classifications of recalls be reported to the FDA within 10 working days after the recall is initiated. Companies
are required to maintain certain records of recalls, even if they are not reportable to the FDA. We may initiate voluntary recalls involving our products in
the future that we determine do not require notification of the FDA. If the FDA disagrees with our determinations, they could require us to report those
actions as recalls. A future recall announcement could harm our reputation with customers and negatively affect our sales. In addition, the FDA could take
enforcement action for failing to report the recalls when they were conducted.

46 

 
 
If  our  products  cause  or  contribute  to  a  death  or  a  serious  injury,  or  malfunction  in  certain  ways,  we  will  be  subject  to  medical  device  reporting
regulations, which can result in voluntary corrective actions or agency enforcement actions.

Under the FDA and international medical device reporting regulations, medical device manufacturers are required to report to the applicable regulatory
authority information that a device has, or may have, caused or contributed to a death or serious injury or has malfunctioned in a way that would likely
cause or contribute to death or serious injury if the malfunction of the device or one of our similar devices were to recur. If we fail to report these events
within the required timeframes, or at all, the regulatory authorities could take enforcement action against us. Any such adverse event involving our products
also could result in future voluntary corrective actions, such as recalls or customer notifications, or agency action, such as inspection or enforcement action.
Any corrective action, whether voluntary or involuntary, as well as defending ourselves in a lawsuit, will require the dedication of our time and capital,
distract management from operating our business, and may harm our reputation and financial results.

We may generate a larger portion of our future revenue internationally and would then be subject to increased risks relating to international activities,
which could adversely affect our operating results.

A  significant  portion  of  our  current  revenue  and  anticipated  future  revenue  growth  will  come  from  international  sources  as  we  implement  and  expand
overseas operations. Engaging in international business involves a number of difficulties and risks, including:

·

·

·

·

·

·

·

·

·

·

·

required compliance with existing and changing foreign health care and other regulatory requirements and laws, such as those relating to patient
privacy;

required  compliance  with  anti-bribery  laws,  such  as  the  U.S.  Foreign  Corrupt  Practices  Act,  or  FCPA,  and  U.K.  Bribery  Act,  data  privacy
requirements, labor laws and anti- competition regulations;

export or import restrictions;

various reimbursement and insurance regimes;

laws and business practices favoring local companies;

longer payment cycles and difficulties in enforcing agreements and collecting receivables through certain foreign legal systems;

political and economic instability;

potentially adverse tax consequences, tariffs, customs charges, bureaucratic requirements and other trade barriers;

foreign exchange controls;

difficulties and costs of staffing and managing foreign operations; and

difficulties protecting or procuring intellectual property rights.

As  we  expand  internationally,  our  results  of  operations  and  cash  flows  would  become  increasingly  subject  to  fluctuations  due  to  changes  in  foreign
currency  exchange  rates.  Our  expenses  are  generally  denominated  in  the  currencies  in  which  our  operations  are  located,  which  is  in  the  United  States,
Germany, and Austria. If the value of the U.S. dollar increases relative to foreign currencies in the future, in the absence of a corresponding change in local
currency prices, our future revenue could be adversely affected as we convert future revenue from local currencies to U.S. dollars. Conversely, a weakening
of the value of the U.S dollar relative to foreign currencies would make our operations in Germany and Austria which operate in Euros relatively more
expensive.  If  we  dedicate  resources  to  our  international  operations  and  are  unable  to  manage  these  risks  effectively,  our  business,  operating  results  and
prospects will suffer.

We  face  the  risk  of  potential  liability  under  the  FCPA  for  past  international  distributions  of  products  and  to  the  extent  we  distribute  products  or
otherwise operate internationally in the future.

In the past, we have distributed certain of our products internationally, and in the future, we will distribute our products internationally and possibly engage
in  additional  international  operations.  The  FCPA  prohibits  companies  such  as  us  from  engaging,  directly  or  indirectly,  in  making  payments  to  foreign
government  and  political  officials  for  the  purpose  of  obtaining  or  retaining  business  or  securing  any  other  improper  advantage,  including,  among  other
things, the distribution of products and other international business operations. Like other U.S. companies operating abroad, we may face liability under the
FCPA if we, or third parties we have used to distribute our products or otherwise advance our international business, have violated the FCPA or any of the
relevant  international  equivalents.  Any  violations  of  these  laws,  or  allegations  of  such  violations,  could  disrupt  our  operations,  involve  significant
management  distraction,  involve  significant  costs  and  expenses,  including  legal  fees,  and  could  result  in  a  material  adverse  effect  on  our  business,
prospects, financial condition or results of operations. We could also suffer severe penalties, including criminal and civil penalties, disgorgement and other
remedial measures.

47 

 
 
Risks Related to Compliance with Healthcare and Regulations

Changes in healthcare policy, including legislation reforming the U.S. healthcare system, may have a material adverse effect on our financial condition
and operations.

In  March  2010,  both  the  Patient  Protection  and  Affordable  Care  Act,  or  Affordable  Care  Act,  and  the  reconciliation  law  known  as  Health  Care  and
Education Reconciliation Act, with the Affordable Care Act, the 2010 Health Care Reform Legislation, were enacted. The constitutionality of the 2010
Health Care Reform Legislation was confirmed twice by the Supreme Court of the United States. The 2010 Health Care Reform Legislation has changed
the existing state of the health care system by expanding coverage through voluntary state Medicaid expansion, attracting previously uninsured persons
through the health care insurance exchanges and by modifying the methodology for reimbursing medical services, drugs and devices. The U.S. Congress is
seeking to replace the 2010 Health Care Reform Legislation. At this time the Company is not certain as to the impact of federal health care legislation on its
business.

The  2010  Health  Care  Reform  Legislation  includes  the  Open  Payments  Act  (formerly  referred  to  as  the  Physician  Payments  Sunshine  Act),  which,  in
conjunction with its implementing regulations, requires manufacturers of certain drugs, biologics, and devices that are reimbursed by Medicare, Medicaid
and the Children’s Health Insurance Program to report annually certain payments or “transfers of value” provided to physicians and teaching hospitals and
to report annually ownership and investment interests held by physicians and their immediate family members during the preceding calendar year. Recent
amendments to the Open Payments Act expand the categories of health care providers for which reporting is required. The failure to report appropriate data
accurately,  timely,  and  completely  could  subject  us  to  significant  financial  penalties.  Other  countries  and  several  states  currently  have  similar  laws  and
more may enact similar legislation.

We cannot predict whether future healthcare initiatives will be implemented at the federal or state level or in countries outside of the United States in which
we may do business, or the effect any future legislation or regulation will have on us. Any changes in government regulation of the United States healthcare
industry may result in decreased profits to us, which may adversely affect our business, financial condition and results of operations.

We are subject to potential enforcement actions involving false claims, kickbacks, physician self-referral or other federal or state fraud and abuse laws,
and we could incur significant civil and criminal sanctions, which would hurt our business.

The government has made enforcement of the false claims, anti-kickback, physician self-referral and various other fraud and abuse laws a major priority. In
many instances, private whistleblowers also are authorized to enforce these laws even if government authorities choose not to do so. In most of these cases,
private whistleblowers brought the allegations to the attention of federal enforcement agencies. The risk of our being found in violation of these laws and
regulations is increased by the fact that some of the laws and regulations have not been fully interpreted by the regulatory authorities or the courts, and their
provisions are open to a variety of interpretations. We could be subject to enforcement actions under the following laws:

·

·

·

·

the  federal  Anti-Kickback  Statute,  which  constrains  certain  marketing  practices,  educational  programs,  pricing  policies  and  relationships  with
healthcare  providers  or  other  entities  by  prohibiting,  among  other  things,  soliciting,  receiving,  offering  or  paying  remuneration,  directly  or
indirectly, to induce or in return for, the purchase or recommendation of an item or service reimbursable under a federal healthcare program, such
as the Medicare and Medicaid programs;

federal  civil  and  criminal  false  claims  laws  and  civil  monetary  penalty  laws,  which  prohibit,  among  other  things,  individuals  or  entities  from
knowingly  presenting,  or  causing  to  be  presented,  claims  for  payment  from  Medicare,  Medicaid,  or  other  third  party  payors  that  are  false  or
fraudulent;

federal  physician  self-referral  laws,  such  as  the  Stark  Law,  which  prohibit  a  physician  from  making  a  referral  to  a  provider  of  certain  health
services with which the physician or the physician’s family member has a financial interest, and prohibit submission of a claim for reimbursement
pursuant to a prohibited referral; and

state  law  equivalents  of  each  of  the  above  federal  laws,  such  as  anti-kickback  and  false  claims  laws,  which  may  apply  to  items  or  services
reimbursed by any third-party payor, including commercial insurers, many of which differ from each other in significant ways and may not have
the same effect, thus complicating compliance efforts.

If  we  or  our  operations  are  found  to  be  in  violation  of  any  of  these  laws  and  regulations,  we  may  be  subject  to  penalties,  including  civil  and  criminal
penalties, damages, fines, exclusion from participation in U.S. federal or state healthcare programs, such as Medicare and Medicaid, and the curtailment or
restructuring  of  our  operations.  We  will  monitor  changes  in  government  enforcement  as  we  grow  and  expand  our  business.  Any  action  against  us  for
violation of these laws, even if we successfully defend against it, could cause us to incur significant legal expenses, divert our management’s attention from
the operation of our business and hurt our reputation. If we were excluded from participation in U.S. federal healthcare programs, we would not be able to
receive, or to sell our tests to other parties who receive reimbursement from Medicare, Medicaid and other federal programs, and that could have a material
adverse effect on our business.

48 

 
 
Risks Related to Our Intellectual Property

If we cannot license rights to use technologies on reasonable terms, we may not be able to commercialize new products in the future.

In the future, we may license third-party technology to develop or commercialize new products. In return for the use of a third party’s technology, we may
agree to pay the licensor royalties based on sales of our solutions. Royalties are a component of cost of services and affect the margins on our products. We
may also need to negotiate licenses to patents and patent applications after introducing a commercial product. Our business may suffer if we are unable to
enter into the necessary licenses on acceptable terms, or at all, if any necessary licenses are subsequently terminated, if the licensors fail to abide by the
terms of the license or fail to prevent infringement by third parties, or if the licensed patents or other rights are found to be invalid or unenforceable.

If we are unable to protect our intellectual property effectively, our business would be harmed.

We rely on patent protection as well as trademark, copyright, trade secret and other intellectual property rights protection and contractual restrictions to
protect our proprietary technologies, all of which provide limited protection and may not adequately protect our rights or permit us to gain or keep any
competitive advantage. If we fail to protect our intellectual property, third parties may be able to compete more effectively against us and we may incur
substantial litigation costs in our attempts to recover or restrict use of our intellectual property.

We  apply  for  patents  covering  our  products  and  technologies  and  uses  thereof,  as  we  deem  appropriate,  however  we  may  fail  to  apply  for  patents  on
important products and technologies in a timely fashion or at all, or we may fail to apply for patents in potentially relevant jurisdictions. It is possible that
none of our pending patent applications will result in issued patents in a timely fashion or at all, and even if patents are granted, they may not provide a
basis for intellectual property protection of commercially viable products, may not provide us with any competitive advantages, or may be challenged and
invalidated by third parties. It is possible that others will design around our current or future patented technologies. We may not be successful in defending
any challenges made against our patents or patent applications. Any successful third-party challenge to our patents could result in the unenforceability or
invalidity of such patents and increased competition to our business. The outcome of patent litigation can be uncertain and any attempt by us to enforce our
patent rights against others may not be successful, or, if successful, may take substantial time and result in substantial cost, and may divert our efforts and
attention from other aspects of our business.

The  patent  positions  of  life  sciences  companies  can  be  highly  uncertain  and  involve  complex  legal  and  factual  questions  for  which  important  legal
principles remain unresolved. No consistent policy regarding the breadth of claims allowed in such companies’ patents has emerged to date in the United
States  or  elsewhere.  Courts  frequently  render  opinions  in  the  biotechnology  field  that  may  affect  the  patentability  of  certain  inventions  or  discoveries,
including opinions that may affect the patentability of methods for analyzing or comparing DNA.

In particular, the patent positions of companies engaged in the development and commercialization of genomic diagnostic tests, like ours, are particularly
uncertain. Various courts, including the U.S. Supreme Court, have recently rendered decisions that affect the scope of patentability of certain inventions or
discoveries relating to certain diagnostic tests and related methods. These decisions state, among other things, that patent claims that recite laws of nature
(for example, the relationship between blood levels of certain metabolites and the likelihood that a dosage of a specific drug will be ineffective or cause
harm) are not themselves patentable. What constitutes a law of nature is uncertain, and it is possible that certain aspects of genetic diagnostics tests would
be considered natural laws. Accordingly, the evolving case law in the United States may adversely affect our ability to obtain patents and may facilitate
third-party challenges to any owned and licensed patents. The laws of some foreign countries do not protect intellectual property rights to the same extent
as the laws of the United States, and we may encounter difficulties protecting and defending such rights in foreign jurisdictions. The legal systems of many
other countries do not favor the enforcement of patents and other intellectual property protection, particularly those relating to biotechnology, which could
make it difficult for us to stop the infringement of our patents in such countries. Proceedings to enforce our patent rights in foreign jurisdictions could result
in substantial cost and divert our efforts and attention from other aspects of our business.

Changes  in  either  the  patent  laws  or  in  interpretations  of  patent  laws  in  the  United  States  or  other  countries  may  diminish  the  value  of  our  intellectual
property. We cannot predict the breadth of claims that may be allowed or enforced in our patents or in third-party patents. We may not develop additional
proprietary products, methods and technologies that are patentable.

49 

 
 
In addition to pursuing patents on our technology, we take steps to protect our intellectual property and proprietary technology by entering into agreements,
including  confidentiality  agreements,  non-disclosure  agreements  and  intellectual  property  assignment  agreements,  with  our  employees,  consultants,
academic  institutions,  corporate  partners  and,  when  needed,  our  advisors.  Such  agreements  may  not  be  enforceable  or  may  not  provide  meaningful
protection for our trade secrets or other proprietary information in the event of unauthorized use or disclosure or other breaches of the agreements, and we
may not be able to prevent such unauthorized disclosure. If we are required to assert our rights against such party, it could result in significant cost and
distraction.

Monitoring unauthorized disclosure is difficult, and we do not know whether the steps we have taken to prevent such disclosure are, or will be, adequate. If
we were to enforce a claim that a third party had illegally obtained and was using our trade secrets, it would be expensive and time consuming, and the
outcome would be unpredictable. In addition, courts outside the United States may be less willing to protect trade secrets.

We may also be subject to claims that our employees have inadvertently or otherwise used or disclosed trade secrets or other proprietary information of
third parties, or to claims that we have improperly used or obtained such trade secrets. Litigation may be necessary to defend against these claims. If we fail
in defending such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights and face increased competition to our
business. A loss of key research personnel work product could hamper or prevent our ability to commercialize potential products, which could harm our
business. Even if we are successful in defending against these claims, litigation could result in substantial costs and be a distraction to management.

Further, competitors could attempt to replicate some or all of the competitive advantages we derive from our development efforts, willfully infringe our
intellectual  property  rights,  design  around  our  protected  technology  or  develop  their  own  competitive  technologies  that  fall  outside  of  our  intellectual
property rights. Others may independently develop similar or alternative products and technologies or replicate any of our products and technologies. If our
intellectual property does not adequately protect us against competitors’ products and methods, our competitive position could be adversely affected, as
could our business.

We have not yet registered certain of our trademarks in all of our potential markets. If we apply to register these trademarks, our applications may not be
allowed  for  registration  in  a  timely  fashion  or  at  all,  and  our  registered  trademarks  may  not  be  maintained  or  enforced.  In  addition,  opposition  or
cancellation proceedings may be filed against our trademark applications and registrations, and our trademarks may not survive such proceedings. If we do
not secure registrations for our trademarks, we may encounter more difficulty in enforcing them against third parties than we otherwise would.

To the extent our intellectual property offers inadequate protection, or is found to be invalid or unenforceable, we would be exposed to a greater risk of
direct  competition.  If  our  intellectual  property  does  not  provide  adequate  coverage  of  our  competitors’  products,  our  competitive  position  could  be
adversely  affected,  as  could  our  business.  Both  the  patent  application  process  and  the  process  of  managing  patent  disputes  can  be  time  consuming  and
expensive.

We  may  be  involved  in  litigation  related  to  intellectual  property,  which  could  be  time-intensive  and  costly  and  may  adversely  affect  our  business,
operating results or financial condition.

We may receive notices of claims of direct or indirect infringement or misappropriation or misuse of other parties’ proprietary rights from time to time.
Some of these claims may lead to litigation. We cannot assure you that we will prevail in such actions, or that other actions alleging misappropriation or
misuse by us of third-party trade secrets, infringement by us of third-party patents and trademarks or other rights, or the validity of our patents, trademarks
or other rights, will not be asserted or prosecuted against us.

We might not have been the first to make the inventions covered by each of our pending patent applications and we might not have been the first to file
patent applications for these inventions. To determine the priority of these inventions, we may have to participate in interference proceedings, derivation
proceedings,  or  other  post-grant  proceedings  declared  by  the  United  States  Patent  and  Trademark  Office  that  could  result  in  substantial  cost  to  us.  No
assurance can be given that other patent applications will not have priority over our patent applications. In addition, recent changes to the patent laws of the
United  States  allow  for  various  post-grant  opposition  proceedings  that  have  not  been  extensively  tested,  and  their  outcome  is  therefore  uncertain.
Furthermore, if third parties bring these proceedings against our patents, we could experience significant costs and management distraction.

Litigation may be necessary for us to enforce our patent and proprietary rights or to determine the scope, coverage and validity of the proprietary rights of
others.  The  outcome  of  any  litigation  or  other  proceeding  is  inherently  uncertain  and  might  not  be  favorable  to  us,  and  we  might  not  be  able  to  obtain
licenses to technology that we require on acceptable terms or at all. Further, we could encounter delays in product introductions, or interruptions in product
sales, as we develop alternative methods or products. In addition, if we resort to legal proceedings to enforce our intellectual property rights or to determine
the validity, scope and coverage of the intellectual property or other proprietary rights of others, the proceedings could be burdensome and expensive, even
if  we  were  to  prevail.  Any  litigation  that  may  be  necessary  in  the  future  could  result  in  substantial  costs  and  diversion  of  resources  and  could  have  a
material adverse effect on our business, operating results or financial condition.

50 

 
 
As  we  move  into  new  markets  and  applications  for  our  products,  incumbent  participants  in  such  markets  may  assert  their  patents  and  other  proprietary
rights  against  us  as  a  means  of  slowing  our  entry  into  such  markets  or  as  a  means  to  extract  substantial  license  and  royalty  payments  from  us.  Our
competitors and others may now and, in the future, have significantly larger and more mature patent portfolios than we currently have. In addition, future
litigation may involve patent holding companies or other adverse patent owners who have no relevant product revenue and against whom our own patents
may  provide  little  or  no  deterrence  or  protection.  Therefore,  our  commercial  success  may  depend  in  part  on  our  non-infringement  of  the  patents  or
proprietary rights of third parties. Numerous significant intellectual property issues have been litigated, and will likely continue to be litigated, between
existing and new participants in our existing and targeted markets and competitors may assert that our products infringe their intellectual property rights as
part of a business strategy to impede our successful entry into or growth in those markets. Third parties may assert that we are employing their proprietary
technology  without  authorization.  In  addition,  our  competitors  and  others  may  have  patents  or  may  in  the  future  obtain  patents  and  claim  that  making,
having made, using, selling, offering to sell or importing our products infringes these patents. We could incur substantial costs and divert the attention of
our management and technical personnel in defending against any of these claims. Parties making claims against us may be able to obtain injunctive or
other relief, which could block our ability to develop, commercialize and sell products, and could result in the award of substantial damages against us. In
the event of a successful claim of infringement against us, we may be required to pay damages and ongoing royalties, and obtain one or more licenses from
third  parties,  or  be  prohibited  from  selling  certain  products.  We  may  not  be  able  to  obtain  these  licenses  on  acceptable  terms,  if  at  all.  We  could  incur
substantial costs related to royalty payments for licenses obtained from third parties, which could negatively affect our financial results. In addition, we
could  encounter  delays  in  product  introductions  while  we  attempt  to  develop  alternative  methods  or  products  to  avoid  infringing  third-party  patents  or
proprietary rights. Defense of any lawsuit or failure to obtain any of these licenses could prevent us from commercializing products, and the prohibition of
sale of any of our products could materially affect our business and our ability to gain market acceptance for our products.

Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our
confidential information could be compromised by disclosure during this type of litigation. In addition, during the course of this kind of litigation, there
could be public announcements of the results of hearings, motions or other interim proceedings or developments. If securities analysts or investors perceive
these results to be negative, it could have a substantial adverse effect on the price of our common stock.

In addition, our agreements with some of our customers, suppliers or other entities with whom we do business require us to defend or indemnify these
parties to the extent they become involved in infringement claims, including the types of claims described above. We could also voluntarily agree to defend
or indemnify third parties in instances where we are not obligated to do so if we determine it would be important to our business relationships. If we are
required or agree to defend or indemnify third parties in connection with any infringement claims, we could incur significant costs and expenses that could
adversely affect our business, operating results, or financial condition.

The COVID-19 pandemic has continued to adversely impact our business, financial condition and results of operations.

The  COVID-19  pandemic  has  continued  to  impact  the  global  economy  and  has  impacted  our  operations  in  the  United  States  and  abroad,  including  by
negatively  impacting  our  sales  and  revenue. As  a  result,  we  have  implemented  certain  operational  changes  in  order  to  address  the  evolving  challenges
presented by the global pandemic. We have experienced significant reductions in the demand for certain of our products, particularly due to the decline in
elective medical procedures and medical treatment unrelated to COVID-19, which negatively impacted our revenues in fiscal years 2020 and 2021 as well
as into 2022. As the pandemic continues, we expect to continue to experience weakened demand for these products as a result of the reduction in elective
and nonessential procedures, lower utilization of routine testing and related specimen collection, reduced spending by customers due to funding diverted to
fight COVID-19 and reduced demand from research laboratories.

Healthcare  providers,  including  our  strategic  partners  worldwide,  spend  significant  time  dealing  with  COVID-19,  and  may  be  unable  to  continue  to
participate in our clinical activities. For example, some clinical trial sites have imposed and continue to maintain restrictions on site visits by sponsors and
CROs, the initiation of new trials, and new patient enrollment to protect both site staff and patients from possible COVID-19 exposure and to focus medical
resources on patients suffering from COVID-19. The pandemic may therefore delay enrollment in and completion of our clinical trials due to prioritization
of  hospital  resources  toward  the  outbreak,  and  some  patients  may  not  be  able  to  comply  with  clinical  trial  protocols  if  quarantines  impede  patient
movement or interrupt healthcare services. Moreover, due to site and participant availability during the pandemic and in the interest of patient safety, many
of our partners had paused new subject enrollment for most clinical trials during the earlier phase of the pandemic and might do so again.

51 

 
 
 
For ongoing and/or planned future trials, we have seen an increasing number of clinical trial sites imposing restrictions on patient visits to limit risks of
possible  COVID-19  exposure,  and  we  may  experience  issues  with  participant  compliance  with  clinical  trial  protocols  as  a  result  of  quarantines,  travel
restrictions  and  interruptions  to  healthcare  services.  The  current  pressures  on  medical  systems  and  the  prioritization  of  healthcare  resources  toward  the
COVID-19 pandemic have also resulted in interruptions in data collection and submissions for certain clinical trials and delayed starts for certain planned
studies. Further, health regulatory agencies globally may also experience disruptions in their operations as a result of the COVID-19 pandemic. The FDA
and comparable foreign regulatory agencies have had and may continue to have slower response times or be under-resourced, which could significantly
delay  the  FDA’s  ability  to  timely  review  and  process  any  submissions  we  or  our  partners  have  filed  or  may  file.  The  FDA  in  2021  notified  us  that  the
agency  would  continue  prioritizing  emergency  use  authorization  requests  for  diagnostic  products  intended  to  address  the  COVID-19  pandemic  during
2021. Due to delays from such prioritization, we only received a clearance decision on our Acuitas AMR Gene Panel on September 30, 2021, which was
originally targeted for a decision by mid-2020.

As a result of the outbreak, we and certain of our suppliers may also be affected and could experience closures and labor shortages, which could disrupt
activities.  We  could  therefore  face  difficulty  sourcing  key  components  necessary  to  produce  our  product  candidates,  which  may  negatively  affect  our
clinical development activities. Even if we are able to find alternate sources for some of these components, they may cost more, which could affect our
results of operations and financial position.

At this point in time, there remains significant uncertainty relating to the potential effect of the novel coronavirus on our business and results of operations.
As  coronavirus  and  its  mutations  become  more  widespread,  each  day  manufacturing  closures,  travel  restrictions,  quarantined  staff  or  lockdowns  may
remain or worsen, all of which would have a negative impact on our ability to operate our business, financial condition and results of operations as well as
virtual marketing, sales and customer service interactions not being as effective as in-person interactions. While several vaccines have been approved for
use, and with vaccination programs underway in many countries, the limited acceptance of vaccination by many individuals in the United States as well as
in Europe and globally, and potential failure to be effective for all known mutations of the SARS-CoV-2 virus still makes it hard to predict if and when the
pandemic will subside.

Moreover, we have continued to have a subset of our office-based employee population in a remote work environment in an effort to mitigate the spread of
COVID-19, which may exacerbate certain risks to our business, including cybersecurity attacks and risk of phishing due to an increase in the number of
points of potential attack, such as laptops and mobile devices (both of which are now being used in increased numbers).

Customer demand for and our ability to sell and market our products may be adversely affected by the COVID-19 pandemic and the legislative and
regulatory responses thereto.

U.S.  state  and  local  governments  as  well  as  many  governments  around  the  world  have  imposed  orders,  restrictions  and  recommendations  resulting  in
closures of businesses, work stoppages, travel restrictions, quarantine orders, social distancing practices and cancellations of gatherings and events. Such
orders, restrictions and recommendations, combined with fears of the spreading of COVID-19, has and may continue to cause certain of our customers to
delay, cancel or reduce orders of our products and makes it difficult to facilitate meetings with current and potential customers, as our sales personnel often
rely on in-person meetings and interaction with our customers. COVID-19 related restrictions have thus harmed our sales efforts, and continued restrictions
could  have  a  negative  impact  on  our  sales  and  results  of  operations.  We  are  unable  to  accurately  predict  how  these  factors  will  reduce  our  sales  going
forward and when these orders, restrictions and recommendations will be relaxed or lifted. There can be no assurances that our customers and distributors
will resume purchases of our products upon termination of these governmental orders, restrictions and recommendations, particularly if there remains any
continued  community  outbreak  of  COVID-19.  A  prolonged  economic  contraction  or  recession  may  also  result  in  our  customers  seeking  to  reduce  their
costs and expenditures, which could result in lower demand for our products. If our sales decline, or if such lost sales are not recoverable in the future, our
revenues, business and results of operations will be significantly adversely affected.

It is not possible to predict the future of the COVID-19 global pandemic or the development of potential tests or treatments. No assurance can be given
that our products will aid in the testing or the treatment of this virus.

We  offer  products  for  testing  for  the  SARS-CoV-2  virus,  the  causal  pathogen  of  COVID-19.  We  may  offer  other  products  for  testing  or  treatment  of
coronavirus in the future. There can be no assurance that test for which our products are used, or any such future tests will be broadly adopted for use. We
are among many companies that are trying to develop and commercialize tests for COVID-19, most of whom have far greater resources than us. If one of
these companies develops an effective test, our development of such tests may not significantly increase our revenues and results of operations.

52 

 
 
 
 
 
We incurred significant indebtedness as a result of the combination with Curetis, which could have a material adverse effect on our financial condition.

On  April  1,  2020,  we  assumed  the  indebtedness  of  Curetis  GmbH.  As  of  December  31,  2021,  we  owed  indebtedness  of  $25.2  million  of  principal
(including deferred interest of $4.8 million) under a loan provided by the European Investment Bank with maturities in April 2022, June 2023, and June
2024.  In  particular,  approximately  $15  million  of  such  indebtedness  is  due  to  the  European  Investment  Bank  in  April  2022.  While  we  are  evaluating
options to restructure such indebtedness, we may not be able to do so, and in such event, OpGen may not be able to generate sufficient cash to service all of
its indebtedness and may be forced to take other actions to satisfy its obligations under indebtedness that may not be successful. The inability in the future
to repay such indebtedness when due would have a material adverse effect on us.

The business combination transaction with Curetis significantly changed our business and operations. We may continue to face challenges integrating
the Curetis businesses.

Following the consummation of the combination with Curetis, we continued as the operating entity and both the size and geographic scope of our business
significantly increased. Most of the Curetis business is currently conducted in Europe, Asia and other countries outside of the United States, and many of
the OpGen employees are located outside of the United States. We have and may face further challenges integrating such geographically diverse businesses
and  implementing  a  smooth  transition  of  business  focus  and  governance  in  a  timely  or  efficient  manner,  especially  in  light  of  the  global  COVID-19
pandemic.  In  particular,  if  the  effort  we  devote  to  the  continued  integration  of  our  businesses  diverts  more  management  time  or  other  resources  from
carrying  out  our  operations  than  we  originally  planned,  our  ability  to  maintain  and  increase  revenues  as  well  as  manage  our  costs  could  be  impaired.
Furthermore, our capacity to expand other parts of our existing businesses may be impaired. We also cannot assure you that following our combination
with Curetis the combined OpGen group will function as we anticipate, or that significant synergies will result from the business combination. Any of the
above could have a material adverse effect on our business.

We are dependent on the services of our management and other key personnel and members of our board of directors, and if we are not able to retain
these individuals or recruit additional management, our business will suffer.

Our success depends in part on our continued ability to attract, retain, manage and motivate highly qualified management and other key personnel. We are
highly dependent upon our senior management and other members of our management team. The loss of services of any of these individuals, such as the
recent  departure  of  our  former  chief  financial  officer  and  our  former  chairman  and  founder,  could  cause  the  loss  of  critical  Company  knowledge  and
information,  delay  or  prevent  the  successful  development  of  our  products,  initiation  or  completion  of  our  preclinical  studies  and  clinical  trials  or  the
commercialization of our products. Although we have executed employment agreements or offer letters with each member of our senior management team,
we may not be able to retain their services as expected. We do not currently maintain “key person” life insurance on the lives of our executives or any of
our employees. This lack of insurance means that we may not have adequate compensation for the loss of the services of these individuals.

We  will  need  to  expand  and  effectively  manage  our  managerial,  operational,  financial  and  other  resources  in  order  to  successfully  pursue  our  clinical
development  and  commercialization  efforts.  We  may  not  be  successful  in  maintaining  our  unique  company  culture  and  continuing  to  attract  or  retain
qualified management and scientific and clinical personnel in the future due to the intense competition for qualified personnel among biopharmaceutical,
biotechnology and other businesses. Our industry has experienced a high rate of turnover of management personnel in recent years. If we are not able to
attract,  integrate,  retain  and  motivate  necessary  personnel  to  accomplish  our  business  objectives,  we  may  experience  constraints  that  will  significantly
impede the achievement of our development objectives, our ability to raise additional capital and our ability to implement our business strategy.

Our insurance policies are expensive and protect us only from some business risks, which will leave us exposed to significant uninsured liabilities.

We do not carry insurance for all categories of risk that our business may encounter. Some of the policies we currently maintain include general liability,
employee  benefits  liability,  property,  umbrella,  business  interruption,  workers’  compensation,  product  liability,  errors  and  omissions  and  directors’  and
officers’ insurance. We do not know, however, if we will be able to maintain existing insurance with adequate levels of coverage. Any significant uninsured
liability may require us to pay substantial amounts, which would adversely affect our cash position and results of operations.

53 

 
 
 
Integrating the businesses of OpGen and Curetis may disrupt or have a negative impact on OpGen.

We  could  have  difficulty  integrating  the  assets,  personnel  and  businesses  of  OpGen  and  Curetis.  The  proposed  transaction  was  complex  and  we  have
devoted  and  will  need  to  continue  to  devote  significant  time  and  resources  to  further  integrating  the  businesses,  including  in  connection  with  certain
internal corporate restructuring matters. As such, risks that could impact us negatively include:

·

·

·

·

·

·

the difficulty of integrating the acquired companies, and their concepts and operations;

the difficulty in combining our financial operations and reporting;

the potential disruption of the ongoing businesses and distraction of our management;

risks related to international operations;

the potential impairment of relationships with employees and partners as a result of any integration of new management personnel; and

the potential inability to manage an increased number of locations and employees.

If we are not successful in addressing these risks effectively, our business could be severely impaired. 

While we currently qualify as a smaller reporting company under SEC regulations, we cannot be certain if we take advantage of the reduced disclosure
requirements  applicable  to  these  companies  so  that  we  will  not  make  our  common  stock  less  attractive  to  investors.  Once  we  lose  smaller  reporting
company status, the costs and demands placed upon our management are expected to increase.

The SEC’s rules permit smaller reporting companies to take advantage of certain exemptions from various reporting requirements applicable to other public
companies. As long as we qualify as a smaller reporting company, based on our public float, and report less than $100 million in annual revenues in a fiscal
year we are permitted, and we intend to, omit the auditor’s attestation on internal control over financial reporting that would otherwise be required by the
Sarbanes-Oxley Act.

We lost our status as an emerging growth company as of December 31, 2020. While we expect to remain a smaller reporting company and non-accelerated
filer, we now face increased disclosure requirements as a non-emerging growth company, such as stockholder advisory votes on executive compensation
(“say-on-pay”). Until such time that we lose smaller reporting company status, it is unclear if investors will find our common stock less attractive because
we may rely on certain disclosure exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market
for our common stock and our stock price may be more volatile and could cause our stock price to decline.

As a result of the loss of our emerging growth company status, we expect the costs and demands placed upon our management to increase, as we now have
to comply with additional disclosure and accounting requirements. In addition, even if we remain a smaller reporting company, if our public float exceeds
$75  million  and  we  report  $100  million  or  more  in  annual  revenues  in  a  fiscal  year,  we  will  become  subject  to  the  provisions  of  Section  404(b)  of  the
Sarbanes-Oxley Act requiring an independent registered public accounting firm to provide an attestation report on the effectiveness of our internal control
over financial reporting, making the public reporting process more costly.

General Risk Factors

We  incur  increased  costs  and  demands  on  management  as  a  result  of  compliance  with  laws  and  regulations  applicable  to  public  companies,  which
could harm our operating results.

As a public company, we incur significant legal, accounting and other expenses that we did not incur as a private company, including costs associated with
public company reporting requirements. In addition, the Sarbanes-Oxley Act of 2002 and the Dodd-Frank Act of 2010, as well as rules implemented by the
SEC and the Nasdaq Stock Market, impose a number of requirements on public companies, including with respect to corporate governance practices. Our
management and other personnel need to devote a substantial amount of time to these compliance and disclosure obligations. Moreover, compliance with
these  rules  and  regulations  has  increased  our  legal,  accounting  and  financial  compliance  costs  and  has  made  some  activities  more  time-consuming  and
costly. It is also more expensive for us to obtain director and officer liability insurance.

54 

 
 
 
 
 
 
 
We may be adversely affected by the current economic environment and future adverse economic environments.

Our  ability  to  attract  and  retain  customers,  invest  in  and  grow  our  business  and  meet  our  financial  obligations  depends  on  our  operating  and  financial
performance, which, in turn, is subject to numerous factors, including the prevailing economic conditions and financial, business and other factors beyond
our control, such as the rate of unemployment, the number of uninsured persons in the United States and inflationary pressures. We cannot anticipate all the
ways in which the current economic climate and financial market conditions, and those in the future, could adversely impact our business.

We  are  exposed  to  risks  associated  with  reduced  profitability  and  the  potential  financial  instability  of  our  customers,  many  of  which  may  be  adversely
affected  by  volatile  conditions  in  the  financial  markets.  For  example,  unemployment  and  underemployment,  and  the  resultant  loss  of  insurance,  may
decrease the demand for healthcare services and diagnostic testing. If fewer patients are seeking medical care because they do not have insurance coverage,
we may experience reductions in revenues, profitability and/or cash flow. In addition, if economic challenges in the United States result in widespread and
prolonged unemployment, either regionally or on a national basis, a substantial number of people may become uninsured or underinsured. To the extent
such economic challenges result in less demand for our proprietary tests, our business, results of operations, financial condition and cash flows could be
adversely affected.

Item 2. Properties

The  Company  leases  10,100  square  feet  of  office  and  laboratory  space  at  our  headquarters  in  Rockville,  Maryland.  The  lease  term  expires  in  February
2032. The Company had also leased 12,770 square feet of space at its facility in Woburn, Massachusetts under an operating lease that expired in January
2022. The Company entered into a sublease agreement for this space in February 2021 that expired in January 2022.

Curetis  leases  approximately  17,000  square  feet  of  manufacturing  and  logistics  space  for  its  FDA  registered  manufacturing  plant  in  Bodelshausen,
Germany, which include tailored cleanrooms, automated Application Cartridge manufacturing equipment and laboratory facilities. The lease term expires
in  June  2025.  Furthermore,  Curetis  leases  approximately  17,000  square  feet  of  office  and  lab  space  at  its  FDA  registered  headquarters  located  in
Holzgerlingen,  Germany,  which  are  used  for  research  and  development,  operations,  and  general  and  administrative  purposes.  The  lease  term  expires  in

Overview

OpGen is a precision medicine company harnessing the power of molecular diagnostics and informatics to help combat infectious disease. Along with our
subsidiaries,  Curetis  GmbH  and  Ares  Genetics  GmbH,  we  are  developing  and  commercializing  molecular  microbiology  solutions  helping  to  guide
clinicians with more rapid and actionable information about life threatening infections to improve patient outcomes and decrease the spread of infections
caused  by  multidrug-resistant  microorganisms,  or  MDROs.  Our  current  product  portfolio  includes  Unyvero,  Acuitas  AMR  Gene  Panel,  and  the  ARES
Technology Platform including ARESdb, using NGS technology and AI-powered bioinformatics solutions for antibiotic response prediction, as well as the
Curetis CE-IVD-marked PCR-based SARS-CoV-2 test kit. The Company exited its FISH business in early 2021, and the Company's license agreement
with Life Technologies, a subsidiary of Thermo Fisher, was terminated as of June 30, 2021.

On April 1, 2020, the Company completed a business combination transaction whereby the Company acquired Curetis GmbH, a private limited liability
company  organized  under  the  laws  of  the  Federal  Republic  of  Germany  (“Curetis  GmbH”).  Curetis  is  an  early  commercial-stage  molecular  diagnostics
(MDx) company focused on rapid infectious disease testing for hospitalized patients with the aim to improve the treatment of hospitalized, critically ill
patients with suspected microbial infection and has developed the innovative Unyvero molecular diagnostic solution for comprehensive infectious disease
testing. The business combination transaction was designed principally to leverage each company’s existing research and development and relationships
with hospitals and clinical laboratories to accelerate the sales of both companies’ products and services.

The focus of OpGen is on its combined broad portfolio of products, which includes high impact rapid diagnostics and bioinformatics to interpret AMR
genetic data. The Company currently expects to focus on the following products for lower respiratory infection, urinary tract infection and invasive joint
infection:

·

·

·

The  Unyvero  Lower  Respiratory  Tract,  or  LRT,  test  (e.g.  for  bacterial  pneumonias)  is  the  first  U.S.  Food  and  Drug  Administration,  or  FDA,
cleared test that can be used for the detection of more than 90% of common causative agents of hospitalized pneumonia. According to the National
Center for Health Statistics (2018), pneumonia is a leading cause of admissions to the hospital and is associated with substantial morbidity and
mortality. The Unyvero LRT automated test detects 19 pathogens within less than five hours, with approximately two minutes of hands-on time
and provides clinicians with a comprehensive overview of 10 genetic antibiotic resistance markers. We have commercialized the Unyvero LRT
BAL test for testing bronchoalveolar lavage, or BAL, specimens from patients with lower respiratory tract infections following FDA clearance
received by Curetis in December 2019. The Unyvero LRT BAL automated test simultaneously detects 20 pathogens and 10 antibiotic resistance
markers,  and  it  is  the  first  and  only  FDA-cleared  panel  that  also  includes  Pneumocystis  jirovecii,  a  key  fungal  pathogen  often  found  in
immunocompromised  patients  (such  as  AIDS  and  transplant  patients)  that  can  be  difficult  to  diagnose,  as  the  20th  pathogen  on  the  panel.  We
believe the Unyvero LRT and LRT BAL tests have the ability to help address a significant, previously unmet medical need that causes over $10
billion in annual costs for the U.S. healthcare system, according to the Centers for Disease Control, or CDC.

Following registration of the Unyvero instrument system as an IVD for the Chinese market in early 2021, we are supporting our strategic partner
BCB in pursuing execution of a supplemental clinical trial with the Unyvero HPN test. As requested by the Chinese regulatory authority NMPA,
this study is geared towards generating additional data in China that will complement a larger data set with data from abroad compiled from other
clinical and analytical studies performed in the past.

The Unyvero Urinary Tract Infection, or UTI, test, which is CE-IVD marked in Europe, is currently being made available to laboratories in the
United States as a research use only or RUO kit. The test detects a broad range of pathogens as well as antimicrobial resistance markers directly
from native urine specimens. We initiated a prospective multi-center clinical trial for the Unyvero UTI in the United States in the third quarter of
2021.

58 

 
 
 
 
 
 
 
 
·

·

The Unyvero Invasive Joint Infection, or IJI, test, which is a variant being developed for the U.S. market, has also been selected for analytical and
clinical performance evaluation including clinical trials towards a future U.S. FDA submission. Microbial diagnosis of IJI is difficult because of
challenges  in  sample  collection,  usually  at  surgery,  and  patients  being  on  prior  antibiotic  therapy  which  minimizes  the  chances  of  recovering
viable  bacteria.  We  believe  that  Unyvero  IJI  could  be  useful  in  identifying  pathogens  as  well  as  their  AMR  markers  to  help  guide  optimal
antibiotic treatment for these patients.

On September 30, 2021, we received clearance from the FDA for our Acuitas AMR Gene Panel for bacterial isolates. The Acuitas AMR Gene
Panel  detects  28  genetic  antimicrobial  resistance,  or  AMR,  markers  in  isolated  bacterial  colonies  from  26  different  pathogens.  We  believe  the
panel  provides  clinicians  with  a  valuable  diagnostic  tool  that  informs  about  potential  antimicrobial  resistance  patterns  early  and  supports
appropriate antibiotic treatment decisions in this indication. We expect to commercialize the Acuitas AMR Gene Panel for isolates more broadly to
customers in the United States.

· We are also developing novel bioinformatics tools and solutions to accompany or augment our current and potential future IVD products and may
seek regulatory clearance for such bioinformatics tools and solutions to the extent they would be required either as part of our portfolio of IVD
products or even as a standalone bioinformatics product.

OpGen has extensive offerings of additional IVD tests including CE-IVD-marked Unyvero tests for hospitalized pneumonia patients, implant and tissue
infections,  intra-abdominal  infections,  complicated  urinary  tract  infections,  and  blood  stream  infections.  Our  portfolio  furthermore  includes  a  CE-IVD-
marked PCR based rapid test kit for SARS-CoV-2 detection in combination with our PCR compatible universal lysis buffer (PULB).

OpGen’s combined AMR bioinformatics offerings, when and if such products are cleared for marketing, will offer important new tools to clinicians treating
patients with AMR infections. OpGen’s subsidiary Ares Genetics’ ARESdb is a comprehensive database of genetic and phenotypic information. ARESdb
was originally designed based on the Siemens microbiology strain collection covering resistant pathogens and its development has significantly expanded,
also by transferring data from the discontinued Acuitas Lighthouse into ARESdb to now cover > 78,000 bacterial isolates that have been sequenced using
NGS technology and tested for susceptibility with applicable antibiotics from a range of over 100 antimicrobial drugs. In the fourth quarter of 2021, Ares
Genetics entered into a strategic database access deal with one of the world’s leading microbiology and IVD corporations for their non-exclusive access to
approximately  1.1%  of  Ares  Genetics’  total  database  asset  at  the  time  of  signing.  Ares  Genetics  continues  to  explore  various  discussions  with  several
interested parties in potential future collaboration or licensing opportunities. Additional partnerships with a U.S. CLIA lab, CRO and a major University
Medical Center have been initiated and are ongoing and the collaboration master service agreement with Sandoz has recently been extended until January
2025.

In addition to potential future licensing and partnering, Ares Genetics intends to independently utilize the proprietary biomarker content in this database, as
well as to build an independent business in NGS and AI based offerings for AMR research and diagnostics in collaboration with its current and potential
future  partners  in  the  life  science,  pharmaceutical  and  diagnostics  industries.  Ares  Genetics  signed  up  Siemens  Technology  Accelerator  and  AGES
(Austrian Agency for Health and Food Safety), as well as several other national institutions from various European countries as new customers.

OpGen’s subsidiary Curetis’ Unyvero A50 tests for up to 130 diagnostic targets (pathogens and resistance genes) in under five hours with approximately
two minutes of hands-on time. The system was first CE-IVD-marked in 2012 and was FDA cleared in 2018 along with the LRT test through a De Novo
request. The  Unyvero  A30  RQ  is  a  new  device  designed  to  address  the  low-to  mid-plex  testing  market  for  5-30  DNA  targets  and  to  provide  results  in
approximately  30  to  90  minutes  with  2-5  minutes  of  hands-on  time.  The  Unyvero  A30  RQ has a small benchtop footprint and has an attractive cost of
goods profile. Curetis has been following a partnering strategy for the Unyvero A30 RQ and, following the successful completion of a key development
milestone,  Curetis  has  completed  final  verification  and  validation  testing  of  the  A30  instruments  and  is  actively  engaged  in  several  ongoing  partnering
discussions and due diligence under respective material transfer agreements.

The Company has extensive partner and distribution relationships to help accelerate the establishment of a global infectious disease diagnostic testing and
informatics business. The Company’s partners include A. Menarini Diagnostics S.r.l. for pan-European distribution to currently 12 countries and Beijing
Clear Biotech Co. Ltd. for Unyvero A50 product distribution in China. We have a network of distributors covering countries in Europe, the Middle East
and  Africa,  Asia  Pacific  and  Latin  America.  With  the  discontinuation  of  our  FISH  products  business  in  Europe,  we  have  reduced  our  network  of
distributors to only those distributors actively commercializing our Unyvero line of products or CE-IVD-marked SARS-CoV-2 test kits.

OpGen will continue to develop and seek FDA and other regulatory clearances or approvals, as applicable, for our Unyvero UTI and IJI products. OpGen
will continue to offer the FDA-cleared Unyvero LRT and LRT BAL Panels, and FDA-cleared Acuitas AMR Gene Panel tests, as well as the Unyvero UTI
Panel as a RUO product to hospitals, public health departments, clinical laboratories, pharmaceutical companies and CROs. OpGen’s subsidiary, Curetis,
continues its preparations for achieving compliance with the upcoming European Union’s In-Vitro-Diagnostic Device Regulation (IVDR), which officially
will go into effect in May 2022. Given the lack of designated Notified Bodies at this time, and with the recently approved EU commission proposal to
provide for generous multi-year grace periods for IVD products with current In-Vitro-Diagnostic Device Directive (IVDD) CE marking, it is now possible
for  Curetis  to  continue  its  portfolio  of  existing  CE-IVD  marked  products  until  at  least  May  2025  and  May  2026,  respectively,  as  long  as  no  material
changes  are  being  made  to  any  of  its  products.  Following  May  2022,  however,  any  new  or  changed  CE  marked  products  will  be  required  to  be  IVDR
compliant from the outset.

Our  headquarters  are  in  Rockville,  Maryland,  and  our  principal  operations  are  in  Rockville,  Maryland  and  Holzgerlingen  and  Bodelshausen,  both  in
Germany. We also have operations in Vienna, Austria. We operate in one business segment.

Financing Transactions 

Since inception, the Company has incurred, and continues to incur, significant losses from operations. The Company has funded its operations primarily
through external investor financing arrangements. The following financing transactions took place during 2020 and 2021:

·

·

·

·

·

On February 11, 2020, the Company entered into an at-the-market sales agreement (the “ATM Agreement”) with H.C. Wainwright & Co., which
was subsequently amended and restated on November 13, 2020, to add BTIG as a sales agent, pursuant to which the Company may offer and sell
from time to time in an “at the market offering,” at its option, up to an aggregate of $22.1 million of shares of its common stock through the sales
agents. During the year ended December 31, 2020, the Company sold 7,521,610 shares of its common stock under the ATM Offering resulting in
aggregate  net  proceeds  of  approximately  $15.8  million,  and  gross  proceeds  of  $16.7  million.  During  the  year  ended  December  31,  2021,  the
Company sold 680,000 shares of its common stock under the ATM Offering resulting in aggregate net proceeds of approximately $1.48 million,
and gross proceeds of $1.55 million.

On November 25, 2020, the Company closed a private placement with one healthcare-focused U.S. institutional investor of (i) 2,245,400 shares of
common  stock  together  with  2,245,400  warrants  (the  “Common  Warrants”)  to  purchase  up  to  2,245,400  shares  of  common  stock  and  (ii)
2,597,215 pre-funded warrants (the “Pre-Funded Warrants”), with each Pre-Funded Warrant exercisable for one share of common stock, together
with  2,597,215  Common  Warrants  to  purchase  up  to  2,597,215  shares  of  common  stock.  Each  share  of  common  stock  and  accompanying
Common Warrant were sold together at a combined offering price of $2.065, and each Pre-funded Warrant and accompanying Common Warrant
were sold together at a combined offering price of $2.055. The Common Warrants have an exercise price of $1.94 per share and are exercisable
commencing  on  the  six  month  anniversary  of  the  date  of  issuance,  and  will  expire  five  and  one  half  (5.5)  years  from  the  date  of  issuance
(collectively, the “2020 PIPE”). The 2020 PIPE raised aggregate net proceeds of $9.3 million, and gross proceeds of $10.0 million.

During  the  year  ended  December  31,  2020,  approximately  4.3  million  common  warrants  issued  in  a  public  offering  that  we  consummated  in
October 2019 were exercised, raising net proceeds of approximately $8.7 million.

On  February  11,  2021,  the  Company  closed  a  registered  direct  offering  (the  "February  2021  Offering”)  with  a  single  U.S.-based,  healthcare-
focused institutional investor for the purchase of (i) 2,784,184 shares of common stock and (ii) 5,549,149  pre-funded  warrants,  with  each  pre-
funded  warrant  exercisable  for  one  share  of  common  stock.  The  Company  also  issued  to  the  investor,  in  a  concurrent  private  placement,
unregistered common share purchase warrants to purchase 4,166,666 shares of the Company’s common stock. Each share of common stock and
accompanying  common  warrant  were  sold  together  at  a  combined  offering  price  of  $3.00,  and  each  pre-funded  warrant  and  accompanying
common warrant were sold together at a combined offering price of $2.99. The pre-funded warrants were immediately exercisable, at an exercise
price of $0.01, and could be exercised at any time until all of the pre-funded warrants are exercised in full. The common warrants have an exercise
price of $3.55 per share, are exercisable commencing on the six-month anniversary of the date of issuance, and will expire five and one-half (5.5)
years from the date of issuance. The February 2021 Offering raised aggregate net proceeds of $23.5 million, and gross proceeds of $25.0 million.
As of December 31, 2021, all 5,549,149 pre-funded warrants issued in the February 2021 Offering have been exercised.

On  March  9,  2021,  the  Company  entered  into  a  Warrant  Exercise  Agreement  (the  “Exercise  Agreement”)  with  the  institutional  investor  (the
“Holder”)  from  our  2020  PIPE.  Pursuant  to  the  Exercise  Agreement,  in  order  to  induce  the  Holder  to  exercise  all  of  the  remaining  4,842,615
outstanding warrants acquired in the 2020 PIPE (the “Existing Warrants”) for cash, pursuant to the terms of and subject to beneficial ownership
limitations contained in the Existing Warrants, the Company agreed to issue to the Holder new warrants (the “New Warrants”) to purchase 0.65
shares of common stock for each share of common stock issued upon such exercise of the Existing Warrants pursuant to the Exercise Agreement
for an aggregate of 3,147,700 New Warrants. The terms of the New Warrants are substantially similar to those of the Existing Warrants, except
that the New Warrants have an exercise price of $3.56. The New Warrants are immediately exercisable and will expire five years from the date of
the Exercise Agreement. The Holder paid an aggregate of $255,751 to the Company for the purchase of the New Warrants. The Company received
aggregate gross proceeds before expenses of approximately $9.65 million from the exercise of the remaining Existing Warrants held by the Holder
and the payment of the purchase price for the New Warrants (together, the “2021 Warrant Exercise”).

·

On October 18, 2021, the Company closed a registered direct offering (the “October 2021 Offering”) with a single healthcare-focused institutional
investor of 150,000 shares of convertible preferred stock and warrants to purchase up to an aggregate of 7,500,000 shares of common stock. The
shares of preferred stock had a stated value of $100 per share and were converted into an aggregate of 7,500,000 shares of common stock at a
conversion  price  of  $2.00  per  share  after  the  Company  received  stockholder  approval  for  an  increase  to  its  number  of  authorized  shares  of
common stock, which approval occurred at the Company’s special meeting of stockholders held in December 2021. Thereafter, all preferred stock
was converted into 7,500,000 common shares in December 2021 so that there were no shares of preferred stock outstanding as of December 31,
2021. The warrants have an exercise price of $2.05 per share, will become exercisable six months following the date of issuance, and will expire
five years following the initial exercise date. The October 2021 Offering raised aggregate net proceeds of $13.9 million, and gross proceeds of
$15.0 million.

The Company’s total revenue for the year ended December 31, 2021 increased 2%, to $4.3 million from $4.2 million, when compared to the same period in
2020. This increase is primarily attributable to:

·

·

·

Product  Sales:  the  decrease  in  revenue  of  approximately  2%  in  2021  compared  to  2020  is  primarily  attributable  to the  loss  of  FISH  products
revenue following the discontinuation of the FISH business, offset, in part, by an increase in the Company’s Unyvero product sales and the non-
exclusive access to a portion of the ARESdb content;

Laboratory Services: the increase in revenue of approximately 385% in 2021 compared to 2020 is primarily attributable to an increase in Ares
Genetics’  laboratory  services  (approximately  $361,000)  as  well  as  COVID  testing  services  performed  by  the  Company’s  Curetis  subsidiary
(approximately $438,000); and

Collaboration Revenue: the decrease in revenue of approximately 38% in 2021 compared to 2020 is primarily attributable to the conclusion of
non-recurring partnering revenues from a completed research and development collaboration with an IVD partner at Ares Genetics in 2020 and
non-recurring milestone-based revenue from the NYS project.

·

·

·

·

Costs of products sold: expenses for the year ended December 31, 2021 decreased approximately 32% when compared to the same period in 2020.
The decrease in cost of products sold is primarily attributable to the discontinuance of the Company’s FISH line of products, partially offset by
increased costs due to the sale of Curetis products;

Costs of services: expenses for the year ended December 31, 2021 increased approximately 13% when compared to the same period in 2020. The
increase in cost of services is primarily attributable to an increase in laboratory service revenue in 2021;

Research and development: expenses for the year ended December 31, 2021 increased approximately 9% when compared to the same period in
2020. The increase in research and development expenses is primarily attributable to the inclusion of four quarters of such expenses for Curetis
and  Ares  Genetics  in  2021  compared  to  only  three  quarters  of  such  expenses  in  2020,  as  a  result  of  the  Company’s  business  combination
transaction with Curetis closing at the beginning of April 2020;

General and administrative: expenses for the year ended December 31, 2021 increased approximately 13% when compared to the same period in
2020, primarily due to the inclusion of four quarters of such expenses for Curetis and Ares Genetics in 2021 compared to only three quarters of
such expenses in 2020, as a result of the Company’s business combination with Curetis closing at the beginning of April 2020;

Sales and marketing: expenses for the year ended December 31, 2021 increased approximately 20% when compared to the same period in 2020,
primarily due to the inclusion of four quarters of such expenses for Curetis and Ares Genetics in 2021 compared to only three quarters of such
expenses in 2020, as a result of the Company’s business combination with Curetis closing at the beginning of April 2020, partially offset by lower
travel costs;

Transaction costs: transaction costs for the year ended December 31, 2020 represent one-time costs incurred as part of the business combination
with Curetis;

Impairment of right-of-use asset: impairment of right-of-use asset for the year ended December 31, 2021 represents the impairment of our San
Diego, California ROU asset. Impairment of right-of-use asset for the year ended December 31, 2020 represents the impairment of our Woburn,
Massachusetts ROU asset;

Impairment of intangible assets: impairment of intangible assets for the year ended December 31, 2020 represents the write down of intangible
assets acquired from AdvanDx in 2015; and

Gain on sale of equipment: gain on sale of equipment for the year ended December 31, 2020 represents the sale of laboratory equipment to one of
our vendors.

Liquidity and Capital Resources

At December 31, 2021, the Company had cash and cash equivalents of $36.1 million, compared to $13.4 million at December 31, 2020. The Company has
funded its operations primarily through external investor financing arrangements and has raised significant funds in 2021 and 2020, including:

During the year ended December 31, 2020, we sold 7,521,610 shares of common stock under the ATM Agreement resulting in aggregate net proceeds to us
of approximately $15.8 million, and gross proceeds of $16.7 million. During the year ended December 31, 2021, we sold 680,000 shares of common stock
under the ATM Agreement resulting in aggregate net proceeds to us of approximately $1.48 million, and gross proceeds of $1.55 million.

During the year ended December 31, 2020, approximately 4.3 million common warrants issued in our October 2019 public offering were exercised for net
proceeds of approximately $8.7 million.

On November 25, 2020, we closed the 2020 PIPE of (i) 2,245,400 shares of common stock, (ii) 4,842,615 warrants to purchase shares of common stock
and (iii) 2,597,215 pre-funded warrants. The offering raised gross proceeds of approximately $10.0 million and net proceeds of approximately $9.3 million.

On February 11, 2021, we closed the February 2021 Offering for the purchase of (i) 2,784,184 shares of common stock, (ii) 5,549,149 pre-funded warrants,
and (iii) unregistered common share purchase warrants to purchase 4,166,666 shares. The February 2021 Offering raised aggregate net proceeds of $23.5
million, and gross proceeds of $25.0 million.

On  March  9,  2021,  we  closed  the  2021  Warrant  Exercise  resulting  in  the  issuance  of  4,842,615  shares  of  common  stock  and  raising  gross  proceeds  of
approximately $9.65 million and net proceeds of $9.3 million.

On October 18, 2021, we closed the October 2021 Offering of 150,000 shares of convertible preferred stock and warrants to purchase up to an aggregate of
7,500,000 shares of common stock. The October 2021 Offering raised aggregate net proceeds of $13.9 million, and gross proceeds of $15.0 million.

We  expect  that  we  will  need  to  obtain  additional  funding  to  sustain  our  future  operations  and  while  we  have  successfully  raised  capital  in  the  past,  the
ability to raise capital in future periods is not assured. Based on our available cash as of December 31, 2021, we will need to raise additional capital in the
next twelve months to continue as a going concern. Management’s plan to obtain additional capital may include additional equity or debt financings.

Net cash provided by financing activities
Net  cash  provided  by  financing  activities  in  2021  of  $47.5  million  consisted  primarily  of  net  proceeds  from  the  February  2021  Offering,  2021  Warrant
Exercise, October 2021 Offering, and our 2020 ATM Offering. Net cash provided by financing activities in 2020 of $34.1 million consisted primarily of net
proceeds from the 2020 PIPE, 2020 ATM Offering and exercises of common stock warrants and the issuance of debt.

Funding requirements

Our  primary  use  of  cash  is  to  fund  operating  expenses,  including  our  research  and  development  and  commercialization  expenditures  as  well  as  general
administrative and corporate purposes. Our future funding requirements will depend on many factors, including the following:

·

·

·

·

·

·

·

·

·

·

·

·

the  initiation,  progress,  timing,  costs  and  results  of  research  and  development  programs,  including  analytical  studies  and  clinical  trials  for  our
products;

the clinical development plans we establish for these products;

the number and characteristics of products that we develop;

the outcome, timing and cost of meeting regulatory requirements established by the FDA and other comparable foreign regulatory authorities;

the  terms  of  our  existing  and  any  future  license  or  collaboration  agreements  we  may  choose  to  enter  into,  including  the  amount  of  upfront,
milestone and royalty obligations;

the other costs associated with in-licensing new technologies, such as any increased costs of research and development and personnel;

the cost of filing, prosecuting, defending and enforcing our patent claims and other intellectual property rights;

the  cost  of  defending  intellectual  property  disputes,  including  patent  infringement  actions  brought  by  third  parties  against  us  or  our  product
candidates;

the effect of competing technological and market developments;

the  degree  of  commercial  success  achieved  following  the  successful  completion  of  development  and  regulatory  approval  activities  for  our
products;

the cost to establish and maintain collaborations on favorable terms, if at all; and

the cost to comply with our obligations as a public company.

We intend to spend substantial amounts on research and development activities, including product development, regulatory and compliance, clinical studies
in support of our future product offerings, and commercial activities. In addition, as of December 31, 2021, we had approximately $25.2 million, including
deferred interest of approximately $4.8 million, due under our senior, unsecured loan financing facility with the EIB. Approximately $15 million is due
under such facility in April 2022. Management may repay such amount in cash or through the issuance of additional equity to the EIB or other restructuring
transactions with the EIB. We cannot assure you that additional financing will not be required in the future to support our operations. We intend to use
financing opportunities strategically to continue to strengthen our financial position.

Critical Accounting Estimates

This Management's Discussion and Analysis of Financial Condition and Results of Operations is based on our audited consolidated financial statements,
which have been prepared in accordance with GAAP. The preparation of financial statements in conformity with GAAP requires us to make estimates and
assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements
and the reported amount of revenues and expenses during the reporting period. In our audited consolidated financial statements, estimates are used for, but
not  limited  to,  liquidity  assumptions,  revenue  recognition,  share-based  compensation,  allowances  for  doubtful  accounts  and  inventory  obsolescence,
valuation of derivative financial instruments measured at fair value on a recurring basis, deferred tax assets and liabilities and related valuation allowance,
estimated useful lives of long-lived assets, and the recoverability of long-lived assets. Actual results could differ from those estimates.

A  summary  of  our  significant  accounting  policies  is  included  in  Note  3  to  the  accompanying  audited  consolidated  financial  statements.  Certain  of  our
accounting policies are considered critical, as these policies require significant, difficult or complex judgments by management, often requiring the use of
estimates about the effects of matters that are inherently uncertain.

Business Combinations

We  allocate  the  fair  value  of  purchase  consideration  to  the  tangible  assets  acquired,  liabilities  assumed,  and  intangible  assets  acquired  based  on  their
estimated acquisition date fair values. The excess of the fair value of the purchase consideration over the fair values of the identifiable assets acquired and
liabilities assumed is recorded as goodwill. When determining the fair values of assets acquired and liabilities assumed, we make significant estimates and
assumptions, especially with respect to intangible assets and debt instruments.

Critical estimates in valuing certain intangible assets include but are not limited to future expected cash flows from customer/distributions relationships,
developed technology, and in-process research & development discount rates, and terminal values. Our estimate of fair value is based upon assumptions
believed to be reasonable, but actual results may differ from estimates.

We  determine  the  fair  value  of  assumed  debt  using  a  discounted  cash  flow  analysis  using  interest  rates  for  debt  with  similar  terms  and  maturities.
Differences between the fair value and the stated value is recorded as a discount or premium and amortized over the remaining term using the effective
interest method. We utilize a Monte Carlo simulation method to determine the fair value of conversion notes, which utilizes inputs including the common
stock price, volatility of common stock, the risk-free interest rate and the probability of conversion to common shares at the conversion rate.

Other estimates associated with the accounting for the acquisition may change as additional information becomes available regarding the assets acquired
and liabilities assumed, as more fully discussed in Note 4 – Business Combination of the notes to the consolidated financial statements (see Part II, Item 8
of this Form 10-K).

Revenue Recognition

The Company derives revenues from (i) the sale of Unyvero Application cartridges, Unyvero Systems, SARS CoV-2 tests, Acuitas AMR Gene Panel test
products, (ii) providing laboratory services, (iii) providing collaboration services including funded software arrangements, and license arrangements, and
(iv) granting access to a small subset of the proprietary ARESdb data asset.

The Company analyzes contracts to determine the appropriate revenue recognition using the following steps: (i) identification of contracts with customers,
(ii) identification of distinct performance obligations in the contract, (iii) determination of contract transaction price, (iv) allocation of contract transaction
price to the performance obligations and (v) determination of revenue recognition based on timing of satisfaction of the performance obligation.

The  Company  recognizes  revenues  upon  the  satisfaction  of  its  performance  obligation  (upon  transfer  of  control  of  promised  goods  or  services  to  our
customers) in an amount that reflects the consideration to which it expects to be entitled in exchange for those goods or services.

The Company defers incremental costs of obtaining a customer contract and amortizes the deferred costs over the period that the goods and services are
transferred to the customer. The Company had no material incremental costs to obtain customer contracts in any period presented.

Deferred revenue results from amounts billed in advance to customers or cash received from customers in advance of services being provided.

Impairment of Long-Lived Assets

Property and equipment is reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be
recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future undiscounted net cash
flows expected to be generated by the asset. Recoverability measurement and estimating of undiscounted cash flows is done at the lowest possible level for
which we can identify assets. If such assets are considered to be impaired, impairment is recognized as the amount by which the carrying amount of assets
exceeds the fair value of the assets.

Finite-lived intangible assets include trademarks, developed technology, software and customer relationships. If any indicators were present, the Company
would test for recoverability by comparing the carrying amount of the asset to the net undiscounted cash flows expected to be generated from the asset. If
those net undiscounted cash flows do not exceed the carrying amount (i.e., the asset is not recoverable), the Company would perform the next step, which
is to determine the fair value of the asset and record an impairment loss, if any.

Acquired  In-Process  Research  &  Development  represents  the  fair  value  assigned  to  those  research  and  development  projects  that  were  acquired  in  a
business combination for which the related products have not received regulatory approval and have no alternative future use. IPR&D is capitalized at its
fair  value  as  an  indefinite-lived  intangible  asset,  and  any  development  costs  incurred  after  the  acquisition  are  expensed  as  incurred.  Upon  achieving
regulatory  approval  or  commercial  viability  for  the  related  product,  the  indefinite-lived  intangible  asset  is  accounted  for  as  a  finite-lived  asset  and  is
amortized on a straight-line basis over the estimated useful life. If the project is not completed or is terminated or abandoned, the Company may have an
impairment related to the IPR&D which is charged to expense. Indefinite-lived intangible assets are tested for impairment annually and whenever events or
changes in circumstances indicate that the carrying amount may be impaired. Impairment is calculated as the excess of the asset’s carrying value over its
fair value.

Goodwill represents the excess of the purchase price paid when the Company acquired AdvanDx, Inc. in July 2015 and Curetis in April 2020, over the fair
values of the acquired tangible or intangible assets and assumed liabilities. The Company will conduct an impairment test of goodwill on an annual basis as
of December 31 of each year and will also conduct tests if events occur or circumstances change that would, more likely than not, reduce the Company’s
fair value below its net equity value.

Share-Based Compensation

Share-based payments to employees, directors and consultants are recognized at fair value. The resulting fair value is recognized ratably over the requisite
service period, which is generally the vesting period of the option. The estimated fair value of equity instruments issued to nonemployees is recorded at fair
value on the earlier of the performance commitment date or the date the services required are completed.

For  all  time-vesting  awards  granted,  expense  is  amortized  using  the  straight-line  attribution  method.  For  awards  that  contain  a  performance  condition,
expense is amortized using the accelerated attribution method. Share-based compensation expense recognized is based on the value of the portion of stock-
based  awards  that  is  ultimately  expected  to  vest  during  the  period.  The  fair  value  of  share-based  payments  is  estimated,  on  the  date  of  grant,  using  the
Black-Scholes model. Option valuation models, including the Black-Scholes model, require the input of highly subjective estimates and assumptions, and
changes  in  those  estimates  and  assumptions  can  materially  affect  the  grant-date  fair  value  of  an  award.  These  assumptions  include  the  fair  value  of  the
underlying and the expected life of the award.

See additional discussion of the use of estimates relating to share-based compensation, and a discussion of management’s methodology for developing each
of the assumptions used in such estimates, in Note 3 to the accompanying consolidated financial statements.

Recent Accounting Pronouncements

We  have  reviewed  all  recently  issued  standards  and  have  determined  that,  other  than  as  disclosed  in  Note  3  to  our  consolidated  financial  statements
appearing elsewhere in this filing, such standards will not have a material impact on our consolidated financial statements or do not otherwise apply to our
operations.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

The Company's management evaluated, with the participation of the Company's principal executive and principal financial officer, the effectiveness of the
Company's  disclosure  controls  and  procedures  (as  defined  in  Rules  13a-15(e)  and  15d-15(e)  under  the  Exchange  Act,  as  of  December  31,  2021.  We
maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our reports filed or submitted under the
Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is
accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow for
timely decisions regarding disclosure. Based on their evaluation, management has concluded that the Company's disclosure controls and procedures were
effective as of December 31, 2021.

Changes in Internal Control over Financial Reporting 

For  the  quarter  ended  December  31,  2021,  there  have  been  no  changes  in  the  Company's  internal  controls  over  financial  reporting  that  have  materially
affected, or are reasonably likely to materially affect, the Company's internal controls over financial reporting. 

Management’s Annual Report on Internal Control over Financial Reporting

The Company's management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-
15(f)  and  15d-15(f)  under  the  Exchange  Act).  The  Company's  internal  control  system  was  designed  to  provide  reasonable  assurance  regarding  the
preparation  and  fair  presentation  of  published  financial  statements.  Because  of  its  inherent  limitations,  internal  control  over  financial  reporting  may  not
prevent  or  detect  misstatements.  Also,  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  management,  including  the  Company's  Chief  Executive  Officer  and  Chief  Financial  Officer,  the  Company  assessed  the
effectiveness of internal control over financial reporting as of December 31, 2021. In making this assessment, management used the criteria set forth by the
Committee of Sponsoring Organizations of the Treadway Commission ("COSO") in its statement "Internal Control-Integrated Framework (2013)."

Based on this assessment, management has concluded that, as of December 31, 2021, internal control over financial reporting is effective based on these
criteria.

This Annual Report does not include an attestation report of the Company’s independent registered public accounting firm regarding internal control over
financial reporting. Management’s report was not subject to attestation by the Company’s independent registered public accounting firm pursuant to the
rules of the SEC that permit the Company to provide only management’s report in this Annual Report.

Item 9B. Other Information

None.

Item 9C. Disclosure Regarding Foreign Jurisdictions that Prevent Inspections

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and Board of Directors of OpGen, Inc.

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of OpGen, Inc and subsidiaries (the “Company”) as of December 31, 2021 and 2020, and
the  related  consolidated  statements  of  operations  and  comprehensive  loss,  stockholders’  equity  and  cash  flows  for  the  years  then  ended  and  the  related
notes (collectively referred to as the “financial statements”). In our opinion, the financial statements referred to above present fairly, in all material respects,
the financial position of the Company as of December 31, 2021 and 2020, and the results of its operations and its cash flows for the years then ended in
conformity with accounting principles generally accepted in the United States of America.

The Company’s Ability to Continue as a Going Concern

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 2 to the
financial  statements,  the  Company  has  incurred  recurring  losses  from  operations  since  inception  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 financial statements do not include any adjustments that might result from the outcome of this uncertainty.

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 audits 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 critical audit matters does not alter in any way our opinion
on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical
audit matters or on the accounts or disclosures to which they relate.

F-2

Valuation of Inventory

As of December 31, 2021, the Company had $4.7 million of inventory which included $0.9 million of raw materials and supplies, $0.1 million in work-in-
process and $3.7 million in finished goods. As disclosed in Note 3 to the financial statements, inventories are stated at the lower of cost or net realizable
value.  The  Company  assesses  its  inventory  levels  along  with  its  purchase  commitments  each  reporting  period  that  is  either  expected  to  be  at  risk  of
expiration prior to sale or has a cost basis in excess of its net realizable value. The Company’s evaluation takes into consideration historic usage, forecasted
demand,  probability  of  regulatory  approval  and  anticipated  sales  price.  The  Company  uses  the  most  recently  developed  sales  forecast  to  refine  the
estimated demand to adjust for circumstances in which historical sales are not expected to be representative of future demand including new products with
little or no historical demand, products being replaced or discontinued for which demand is expected to decrease, or other customer specific or economic
factors.

We identified the valuation of inventory as a critical audit matter. Management’s estimates for excess and obsolete inventory involved complex judgments
about future market, regulatory and economic conditions outside the Company’s control. In particular, the excess inventory calculations are sensitive to
significant  assumptions,  including  the  expected  demand  for  the  Company’s  products,  including  the  effect  on  demand  of  competitive  products  and  the
changes in economic, regulatory and market conditions. Given these factors, the related audit effort in evaluating management’s judgements was especially
challenging, subjective, and complex and required a high degree of auditor judgment.

Addressing  the  matter  involved  performing  procedures  and  evaluating  audit  evidence  in  connection  with  forming  our  overall  opinion  on  the  financial
statements.  We  obtained  an  understanding  and  evaluated  the  design  of  internal  controls  over  the  Company’s  excess  or  obsolete  inventory  estimation
process,  including  management’s  assessment  of  the  assumptions  and  data  underlying  the  excess  or  obsolete  inventory  reserves.  Our  substantive  audit
procedures  included,  among  others,  evaluating  the  significant  assumptions  stated  above  and  the  reasonableness  of  the  underlying  data  used  in
management’s  excess  or  obsolete  inventory  assessment.  We  compared  on-hand  inventories  to  demand  forecasts,  assessed  the  reasonableness  of
management’s  demand  forecasts  through  testing  historical  sales  quantities,  and  evaluated  adjustments  to  demand  forecasts  for  specific  product
considerations, such as specific customer demand.

Impairment Assessments—Goodwill, Acquired In-Process Research and Development Costs and Finite-lived Intangibles

As disclosed in Note 3 to the financial statements, the Company’s goodwill, acquired in-process research and development costs (“IPR&D”) and finite-
lived  intangibles  balances  were  $7.5  million,  $5.9  million  and  $8.6  million,  respectively,  as  of  December  31,  2021.  These  assets  are  assessed  for
impairment at least annually, as of the last day of the Company’s fourth fiscal quarter, and as triggering events occur. The impairment test for goodwill
consists  of  comparing  the  fair  value  of  the  reporting  unit  and  acquired  IPR&D,  which  is  estimated  using  both  the  income  and  market  approach,  to  its
carrying value. If the carrying value exceeds the fair value, an impairment loss is recognized in an amount equal to such excess. The Company evaluates
finite-lived intangible assets for potential impairment by comparing estimated future undiscounted net cash flows to the carrying amount of the assets. If
the carrying amount of the assets exceeds the estimated future undiscounted net cash flows, impairment is measured based on the difference between the
carrying amount of the asset and its fair value. The determination of these fair values is primarily based on discounted future cash flows projected to be
generated from these assets, including the estimation of future development costs, the probability of success in various phases of development programs
and  potential  post-launch  cash  flows.  In  performing  both  the  discounted  and  undiscounted  cash  flow  analyses,  management  makes  various  judgments,
estimates and assumptions, the most significant of which are the assumptions related to revenue growth rates, operating profit margin rates, terminal growth
rates, and discount rates. Rates used to discount cash flows are dependent upon interest rates and the cost of capital at a point in time. The market approach
requires use of market price data of guideline public companies to estimate the fair value of the reporting unit. Changes in these assumptions could have a
significant impact on either the fair value, the amount of any impairment charges, or both.

We identified the impairment assessments for goodwill and intangibles as a critical audit matter. Management’s estimates for future cash flows projected to
be generated from these assets involved complex judgments. In particular, the fair value measurement of the reporting unit and intangibles are sensitive to
significant assumptions, including revenue growth rates, operating profit margin rates, terminal growth rates, and discount rates. Given these factors, the
related  audit  effort  in  evaluating  management’s  judgements  was  especially  challenging,  subjective,  and  complex  and  required  a  high  degree  of  auditor
judgment and involved the use of professionals with specialized valuation skill and knowledge.

F-3

Addressing  the  matter  involved  performing  procedures  and  evaluating  audit  evidence  in  connection  with  forming  our  overall  opinion  on  the  financial
statements.  We  obtained  an  understanding  and  evaluated  the  design  of  internal  controls  over  the  Company's  impairment  assessments,  including
management's  assessment  of  the  assumptions  and  data  underlying  the  projected  future  cash  flows.  Our  substantive  audit  procedures  included,  among
others, (i) testing management’s process for developing the fair value estimate of the reporting unit and intangibles; (ii) evaluating the appropriateness of
the  discounted  and  undiscounted  cash  flow  analyses;  (iii)  testing  the  reasonableness  of  underlying  data  used  in  the  analyses;  and  (iv)  evaluating  the
significant assumptions used by management related to the revenue growth rates, operating profit margin rates, terminal growth rates, and discount rates.
Evaluating  management’s  assumptions  related  to  revenue  growth  rates,  operating  profit  margin  rates,  and  terminal  growth  rates  involved  evaluating
whether the assumptions were reasonable considering (i) the current and past performance of the reporting unit and products and technologies associated
with the intangibles; (ii) the consistency with external market and industry data; and (iii) whether these assumptions were consistent with evidence obtained
in  other  areas  of  the  audit.  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.  Professionals  with  specialized
valuation skill and knowledge were used to assist in the evaluation.

Notes to Consolidated Financial Statements

Note 1 - Organization

OpGen,  Inc.  (“OpGen”  or  the  “Company”)  was  incorporated  in  Delaware  in  2001.  On  April  1,  2020,  OpGen  completed  its  business  combination
transaction (the “Transaction”) with Curetis N.V., a public company with limited liability under the laws of the Netherlands (the “Seller” or “Curetis N.V.”),
as contemplated by the Implementation Agreement, dated as of September 4, 2019 (the “Implementation Agreement”), by and among the Company, the
Seller, and Crystal GmbH, a private limited liability company organized under the laws of the Federal Republic of Germany and wholly-owned subsidiary
of the Company (the “Purchaser”). Pursuant to the Implementation Agreement, the Purchaser acquired all of the shares of Curetis GmbH, a private limited
liability company organized under the laws of the Federal Republic of Germany (“Curetis GmbH”), and certain other assets and liabilities of the Seller
(together, “Curetis”) (see Note 4). References to the “Company” include OpGen and its wholly-owned subsidiaries. The Company’s headquarters are in
Rockville, Maryland and the Company’s principal operations are in Rockville, Maryland; Holzgerlingen and Bodelshausen, Germany; and Vienna, Austria.
The Company operates in one business segment.

OpGen Overview

OpGen is a precision medicine company harnessing the power of molecular diagnostics and informatics to help combat infectious disease. Along with our
subsidiaries,  Curetis  GmbH  and  Ares  Genetics  GmbH,  we  are  developing  and  commercializing  molecular  microbiology  solutions  helping  to  guide
clinicians with more rapid and actionable information about life threatening infections to improve patient outcomes and decrease the spread of infections
caused  by  multidrug-resistant  microorganisms,  or  MDROs.  Our  current  product  portfolio  includes  Unyvero,  Acuitas  AMR  Gene  Panel,  and  the  ARES
Technology Platform including ARESdb, using NGS technology and AI-powered bioinformatics solutions for antibiotic response prediction as well as the
Curetis CE-IVD-marked PCR-based SARS-CoV-2 test kit.

Following its initial announcement in October 2020, the Company discontinued its QuickFISH and PNA FISH product portfolio in its entirety during the
first quarter of 2021 (see Note 12). The Company's FISH customers and distribution partners have been informed accordingly and last orders were received
and processed in the first quarter of 2021. The discontinuance of these product lines did not qualify for discontinued operations reporting.

The  focus  of  OpGen  is  on  its  combined  broad  portfolio  of  products,  which  include  high  impact  rapid  diagnostics  and  bioinformatics  to  interpret
Antimicrobial resistance (AMR) genetic data. OpGen will continue to develop and seek FDA and other regulatory clearances or approvals, as applicable,
for  the  Unyvero  UTI  and  IJI  products.  OpGen  will  continue  to  offer  the  FDA-cleared  Unyvero  LRT  and  LRT  BAL  Panels,  Acuitas  AMR  Gene  Panel
diagnostic test, as well as the Unyvero UTI Panel as a RUO product to hospitals, public health departments, clinical laboratories, pharmaceutical companies
and  contract  research  organizations,  or  CROs.  OpGen  will  also  continue  to  commercialize  its  CE  Marked  Unyvero  Panels  in  Europe  and  other  global
markets via distributors.

Note 2 - Going Concern and Management’s Plans

The  accompanying  consolidated  financial  statements  have  been  prepared  on  a  going  concern  basis,  which  contemplates  the  realization  of  assets  and
satisfaction  of  liabilities  in  the  normal  course  of  business.  Since  inception,  the  Company  has  incurred,  and  continues  to  incur,  significant  losses  from
operations and negative operating cash flows and has a significant amount of debt coming due in 2022. The Company has funded its operations primarily
through external investor financing arrangements and significant actions taken by the Company, including the following:

• On October 18, 2021, the Company closed a registered direct offering (the “October 2021 Offering”) with a single healthcare-focused institutional
investor of 150,000 shares of convertible preferred stock and warrants to purchase up to an aggregate of 7,500,000 shares of common stock. The
shares of preferred stock had a stated value of $100 per share and were converted into an aggregate of 7,500,000 shares of common stock at a
conversion price of $2.00 per share after the Company received stockholder approval for an increase to its number of authorized shares of common
stock,  which  approval  occurred  at  the  Company’s  special  meeting  of  stockholders  held  in  December  2021.  Thereafter,  all  preferred  stock  was
converted into 7,500,000 common shares in December 2021 so that there were no shares of preferred stock outstanding as of December 31, 2021.
The warrants have an exercise price of $2.05 per share, will become exercisable six months following the date of issuance, and will expire five
years following the initial exercise date. The October 2021 Offering raised aggregate net proceeds of $13.9 million, and gross proceeds of $15.0
million.

F-9

• On  March  9,  2021,  the  Company  entered  into  a  Warrant  Exercise  Agreement  (the  “Exercise  Agreement”)  with  the  institutional  investor  (the
“Holder”) from our 2020 PIPE financing (see discussion below for a description of the 2020 PIPE). Pursuant to the Exercise Agreement, in order to
induce the Holder to exercise all of the remaining 4,842,615 outstanding warrants acquired in the 2020 PIPE (the “Existing Warrants”) for cash,
pursuant to the terms of and subject to beneficial ownership limitations contained in the Existing Warrants, the Company agreed to issue to the
Holder new warrants (the “New Warrants”) to purchase 0.65 shares of common stock for each share of common stock issued upon such exercise of
the  Existing  Warrants  pursuant  to  the  Exercise  Agreement  for  an  aggregate  of  3,147,700  New  Warrants.  The  terms  of  the  New  Warrants  are
substantially  similar  to  those  of  the  Existing  Warrants,  except  that  the  New  Warrants  have  an  exercise  price  of  $3.56.  The  New  Warrants  are
immediately  exercisable  and  will  expire  five  years  from  the  date  of  the  Exercise  Agreement.  The  Holder  paid  an  aggregate  of  $255,751  to  the
Company for the purchase of the New Warrants. The Company received aggregate gross proceeds before expenses of approximately $9.65 million
from the exercise of the remaining Existing Warrants held by the Holder and the payment of the purchase price for the New Warrants (together, the
“2021  Warrant  Exercise”).  As  additional  compensation,  A.G.P./Alliance  Global  Partners,  the  Company’s  placement  agent  for  such  warrant
exchange, will receive a cash fee equal to $200,000 upon the cash exercise in full of the New Warrants.

• On  February  11,  2021,  the  Company  closed  a  registered  direct  offering  (the  "February  2021  Offering”)  with  a  single  U.S.-based,  healthcare-
focused  institutional  investor  for  the  purchase  of  (i)  2,784,184  shares  of  common  stock  and  (ii)  5,549,149  pre-funded  warrants,  with  each  pre-
funded  warrant  exercisable  for  one  share  of  common  stock.  The  Company  also  issued  to  the  investor,  in  a  concurrent  private  placement,
unregistered common share purchase warrants to purchase 4,166,666 shares of the Company's common stock. Each share of common stock and
accompanying  common  warrant  were  sold  together  at  a  combined  offering  price  of  $3.00,  and  each  pre-funded  warrant  and  accompanying
common warrant were sold together at a combined offering price of $2.99. The pre-funded warrants were immediately exercisable, at an exercise
price of $0.01, and could be exercised at any time until all of the pre-funded warrants are exercised in full. The common warrants have an exercise
price of $3.55 per share, are exercisable commencing on the six-month anniversary of the date of issuance, and will expire five and one-half (5.5)
years from the date of issuance. The February 2021 Offering raised aggregate net proceeds of $23.5 million, and gross proceeds of $25.0 million.
As of December 31, 2021, all 5,549,149 pre-funded warrants issued in the February 2021 Offering have been exercised.

• On November 25, 2020, the Company closed a private placement (the “2020 PIPE”) with one healthcare-focused U.S. institutional investor for the
purchase  of  (i)  2,245,400  shares  of  common  stock,  (ii)  4,842,615  warrants  to  purchase  shares  of  common  stock  and  (iii)  2,597,215  pre-funded
warrants,  with  each  pre-funded  warrant  exercisable  for  one  share  of  common  stock.  Each  share  of  common  stock  and  accompanying  common
warrant were sold together at a combined offering price of $2.065, and each pre-funded warrant and accompanying common warrant were sold
together at a combined offering price of $2.055. The common warrants have an exercise price of $1.94 per share, and are exercisable commencing
on the six-month anniversary of the date of issuance, and will expire five and one-half (5.5) years from the date of issuance. The 2020 PIPE raised
aggregate net proceeds of $9.3 million, and gross proceeds of $10.0 million. As of December 31, 2020, all 2,597,215 pre-funded warrants issued in
the 2020 PIPE were exercised.

• On February 11, 2020, the Company entered into an At the Market Common Offering (the “ATM Agreement”) with H.C. Wainwright & Co., LLC
(“Wainwright”), which was amended and restated on November 13, 2020 to add BTIG, LLC (“BTIG”), pursuant to which the Company may offer
and sell from time to time in an “at the market offering”, at its option, up to an aggregate of $22.1 million of shares of the Company's common
stock through the sales agents (the “2020 ATM Offering”). During the year ended December 31, 2020, the Company sold 7,521,610 shares of its
common  stock  under  the  2020  ATM  Offering  resulting  in  aggregate  net  proceeds  to  the  Company  of  approximately  $15.8  million,  and  gross
proceeds of $16.7 million. During the year ended December 31, 2021, the Company sold 680,000 shares of its common stock under the 2020 ATM
Offering, resulting in aggregate net proceeds to the Company of approximately $1.48 million, and gross proceeds of approximately $1.55 million.

F-10

To  meet  its  capital  needs,  the  Company  is  considering  multiple  alternatives,  including,  but  not  limited  to,  strategic  financings  or  other  transactions,
additional equity financings, debt financings and other funding transactions, licensing and/or partnering arrangements. There can be no assurance that the
Company will be able to complete any such transaction on acceptable terms or otherwise. The Company believes that current cash, will be sufficient to
repay or refinance the current portion of the Company’s debt and fund operations into the fourth quarter of 2022. This has led management to conclude that
there is substantial doubt about the Company’s ability to continue as a going concern. In the event the Company is unable to successfully raise additional
capital  during  or  before  the  end  of  the  fourth  quarter  of  2022,  the  Company  will  not  have  sufficient  cash  flows  and  liquidity  to  finance  its  business
operations  as  currently  contemplated.  Accordingly,  in  such  circumstances,  the  Company  would  be  compelled  to  immediately  reduce  general  and
administrative  expenses  and  delay  research  and  development  projects,  pause  or  abort  clinical  trials  including  the  purchase  of  scientific  equipment  and
supplies, until it is able to obtain sufficient financing. If such sufficient financing is not received on a timely basis, the Company would then need to pursue
a plan to license or sell its assets, seek to be acquired by another entity, cease operations and/or seek bankruptcy protection.

Note 3 - Summary of Significant Accounting Policies

Basis of Presentation

The  accompanying  consolidated  financial  statements  are  prepared  in  accordance  with  accounting  principles  generally  accepted  in  the  United  States  of
America (“GAAP”). The consolidated financial statements consolidate the operations of all controlled subsidiaries; all intercompany activity is eliminated.

Foreign Currency

The Company has subsidiaries located in Holzgerlingen, Germany; Vienna, Austria; and Copenhagen, Denmark, each of which use currencies other than
the U.S. dollar as their functional currency. As a result, all assets and liabilities are translated into U.S. dollars based on exchange rates at the end of the
reporting period. Income and expense items are translated at the average exchange rates prevailing during the reporting period. Translation adjustments are
reported in accumulated other comprehensive income (loss), a component of stockholders’ equity. Foreign currency translation adjustments are the sole
component of accumulated other comprehensive income (loss) at December 31, 2021 and 2020.

Foreign currency transaction gains and losses, excluding gains and losses on intercompany balances where there is no current intent to settle such amounts
in the foreseeable future, are included in the determination of net loss. Unless otherwise noted, all references to “$” or “dollar” refer to the United States
dollar.

Use of Estimates

In preparing financial statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amounts of
assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and
expenses  during  the  reporting  period.  In  the  accompanying  consolidated  financial  statements,  estimates  are  used  for,  but  not  limited  to,  liquidity
assumptions,  revenue  recognition,  inducement  expense  related  to  warrant  repricing,  stock-based  compensation,  allowances  for  doubtful  accounts  and
inventory obsolescence, discount rates used to discount unpaid lease payments to present values, valuation of derivative financial instruments measured at
fair value on a recurring basis, deferred tax assets and liabilities and related valuation allowance, determining the fair value of assets acquired and liabilities
assumed in business combinations, the estimated useful lives of long-lived assets, and the recoverability of long-lived assets. Actual results could differ
from those estimates.

Fair value of financial instruments

Financial instruments classified as current assets and liabilities (including cash and cash equivalent, receivables, accounts payable, deferred revenue and
short-term notes) are carried at cost, which approximates fair value, because of the short-term maturities of those instruments.

For additional fair value disclosures, see Note 6.

Cash and cash equivalents and restricted cash

The Company considers all highly liquid instruments with original maturities of three months or less to be cash equivalents. The Company has cash and
cash equivalents deposited in financial institutions in which the balances occasionally exceed the Federal Deposit Insurance Corporation (“FDIC”) insured
limit of $250,000. The Company has not experienced any losses in such accounts and management believes it is not exposed to any significant credit risk.

F-11

At December 31, 2021 and 2020, the Company had funds totaling $551,794 and $746,792, respectively, which are required as collateral for letters of credit
benefiting  its  landlords  and  for  credit  card  processors.  These  funds  are  reflected  in  other  noncurrent  assets  on  the  accompanying  consolidated  balance
sheets.

The following table provides a reconciliation of cash and cash equivalents and restricted cash reported within the consolidated balance sheets that sum to
the total of the same amounts shown in the consolidated statements of cash flows:

Accounts receivable

The  Company’s  accounts  receivable  result  from  revenues  earned  but  not  collected  from  customers.  Credit  is  extended  based  on  an  evaluation  of  a
customer’s financial condition and, generally, collateral is not required. Accounts receivable are due within 30 to 60 days and are stated at amounts due
from customers. The Company evaluates if an allowance is necessary by considering a number of factors, including the length of time accounts receivable
are past due, the Company’s previous loss history and the customer’s current ability to pay its obligation. If amounts become uncollectible, they are charged
to operations when that determination is made. The allowance for doubtful accounts was $0 and $20,753 as of December 31, 2021 and 2020, respectively.

At  December  31,  2021,  the  Company  had  accounts  receivable  from  two  customers  which  individually  represented  52%  and  14%  of  total  accounts
receivable,  respectively.  At  December  31,  2020,  the  Company  had  accounts  receivable  from  one  customer  which  individually  represented  20%  of  total
accounts  receivable.  For  the  year  ended  December  31,  2021,  revenue  earned  from  three  customers  represented  15%,  13%,  and  12%  of  total  revenues,
respectively. For the year ended December 31, 2020, revenue earned from one customer represented 21% of total revenues.

reagents  and  supplies  used  for  the  Company’s  laboratory  services.  Inventory  reserves  for  obsolescence  and  expirations  were  $98,064  and  $288,378  at
December 31, 2021 and 2020, respectively.

The Company reviews inventory quantities on hand and analyzes the provision for excess and obsolete inventory based primarily on product expiration
dating and its estimated sales forecast, which is based on sales history and anticipated future demand. The Company’s estimates of future product demand
may not be accurate, and it may understate or overstate the provision required for excess and obsolete inventory. Accordingly, any significant unanticipated
changes in demand could have a significant impact on the value of the Company’s inventory and results of operations.

The Company classifies finished good inventory it does not expect to sell or use in clinical studies within 12 months of the consolidated balance sheets date
as strategic inventory, a non-current asset.

Long-lived assets

Property and equipment

Property and equipment is stated at cost and depreciated on a straight-line basis over the estimated useful lives of the related assets. The estimated service
lives range from three to ten years. Depreciation expense was $1,541,561 and $1,152,954 for the years ended December 31, 2021 and 2020, respectively.
Property and equipment consisted of the following at December 31, 2021 and 2020:

Laboratory and manufacturing equipment
Office furniture and equipment
Computers and network equipment

Property and equipment is reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be
recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future undiscounted net cash
flows expected to be generated by the asset. Recoverability measurement and estimating of undiscounted cash flows is done at the lowest possible level for
which we can identify assets. If such assets are considered to be impaired, impairment is recognized as the amount by which the carrying amount of assets
exceeds the fair value of the assets. During the years ended December 31, 2021 and 2020, the Company determined that its property and equipment was not
impaired.

Leases

The Company determines if an arrangement is a lease at inception. For leases where the Company is the lessee, right-of-use (“ROU”) assets represent the
Company’s right to use the underlying asset for the term of the lease and the lease liabilities represent an obligation to make lease payments arising from
the lease. ROU assets and lease liabilities are recognized at the lease commencement date based on the present value of the future lease payments over the
lease  term.  The  Company  uses  its  incremental  borrowing  rate  based  on  the  information  available  at  the  commencement  date  of  the  underlying  lease
arrangement to determine the present value of lease payments. The ROU asset also includes any prepaid lease payments and any lease incentives received.
The lease term to calculate the ROU asset and related lease liability includes options to extend or terminate the lease when it is reasonably certain that the
Company  will  exercise  the  option.  The  Company’s  lease  agreements  generally  do  not  contain  any  material  variable  lease  payments,  residual  value
guarantees or restrictive covenants.

Lease expense for operating leases is recognized on a straight-line basis over the lease term as an operating expense while expense for financing leases is
recognized  as  depreciation  expense  and  interest  expense  using  the  effective  interest  method  of  recognition.  The  Company  has  made  certain  accounting
policy elections whereby the Company (i) does not recognize ROU assets or lease liabilities for short-term leases (those with original terms of 12 months
or less) and (ii) combines lease and non-lease elements of our operating leases.

ROU Assets

ROU  assets  are  reviewed  for  impairment  whenever  events  or  changes  in  circumstances  indicate  that  the  carrying  amount  of  an  asset  may  not  be
recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future undiscounted net cash
flows expected to be generated by the asset. Recoverability measurement and estimating of undiscounted cash flows is done at the lowest possible level for
which the Company can identify assets. If such assets are considered to be impaired, impairment is recognized as the amount by which the carrying amount
of assets exceeds the fair value of the assets. During the year ended December 31, 2021, the Company determined that the ROU asset associated with its
San Diego, California office lease may not be recoverable. As a result, during the year ended December 31, 2021, the Company recorded an impairment
charge of $170,714. The Company also recorded an impairment charge of $101,838 during the year ended December 31, 2020 related to its ROU asset
associated with its Woburn, Massachusetts office lease.

Ares – Developed technology
A30 – Acquired in-process research & development

Estimated Useful Life
10 years
15 years

Indefinite

Acquired IPR&D represents the fair value assigned to those research and development projects that were acquired in a business combination for which the
related  products  have  not  received  regulatory  approval  and  have  no  alternative  future  use.  IPR&D  is  capitalized  at  its  fair  value  as  an  indefinite-lived
intangible  asset,  and  any  development  costs  incurred  after  the  acquisition  are  expensed  as  incurred.  Upon  achieving  regulatory  approval  or  commercial
viability for the related product, the indefinite-lived intangible asset is accounted for as a finite-lived asset and is amortized on a straight-line basis over the
estimated useful life. If the project is not completed or is terminated or abandoned, the Company may have an impairment related to the IPR&D which is
charged to expense. Indefinite-lived intangible assets are tested for impairment annually and whenever events or changes in circumstances indicate that the
carrying amount may be impaired. Impairment is calculated as the excess of the asset’s carrying value over its fair value.

The  Company  reviews  the  useful  lives  of  intangible  assets  when  events  or  changes  in  circumstances  occur  which  may  potentially  impact  the  estimated
useful life of the intangible assets.

F-14

 
 
Total amortization expense of intangible assets was $813,184 and $672,823 for the years ended December 31, 2021 and 2020, respectively. Expected future
amortization of intangible assets is as follows:

Intangible  assets  are  reviewed  for  impairment  whenever  events  or  changes  in  circumstances  indicate  that  the  carrying  amount  of  the  asset  may  not  be
recoverable.  If  any  indicators  were  present,  the  Company  would  test  for  recoverability  by  comparing  the  carrying  amount  of  the  asset  to  the  net
undiscounted cash flows expected to be generated from the asset. If those net undiscounted cash flows do not exceed the carrying amount (i.e., the asset is
not recoverable), the Company would perform the next step, which is to determine the fair value of the asset and record an impairment loss, if any.

In accordance with ASC 360-10, Property, Plant and Equipment, the Company records impairment losses on long-lived assets used in operations when
events and circumstances indicate that long-lived assets might be impaired and the undiscounted cash flows estimated to be generated by those assets are
less  than  the  carrying  amounts  of  those  assets.  During  the  year  ended  December  31,  2020,  events  and  circumstances  indicated  the  Company’s  FISH
intangible assets might be impaired. These circumstances included decreased product sales related to the COVID-19 pandemic and the loss of significant
customers. Management’s updated estimate of undiscounted cash flows indicated that such carrying amounts were no longer expected to be recovered and
that the FISH intangible assets were impaired. The Company’s analysis determined that the fair value of the assets was $0 and the Company recorded an
impairment  loss  of  $750,596.  During  2021,  events  and  circumstances  indicated  the  Company’s  intangible  assets  might  be  impaired.  However,
management’s  estimate  of  undiscounted  cash  flows  indicated  that  such  carrying  amounts  were  expected  to  be  recovered.  Nonetheless,  it  is  reasonably
possible that the estimate of undiscounted cash flows may change in the near term, resulting in the need to write down those assets to fair value.

Goodwill

Goodwill represents the excess of the purchase price paid when the Company acquired AdvanDx, Inc. in July 2015 and Curetis in April 2020, over the fair
values of the acquired tangible or intangible assets and assumed liabilities. Goodwill is not tax deductible in any relevant jurisdictions. The Company’s
goodwill balance as of December 31, 2021 and 2020 was $7,453,007 and $8,024,729, respectively.

The changes in the carrying amount of goodwill as of December 31, 2021, and since December 31, 2019, were as follows:

Balance as of December 31, 2019
Acquisition of Curetis
Changes in currency translation

6,688,652
735,263
8,024,729
(571,722)
7,453,007

The Company conducts an impairment test of goodwill on an annual basis, and will also conduct tests if events occur or circumstances change that would,
more  likely  than  not,  reduce  the  Company’s  fair  value  below  its  net  equity  value.  During  the  years  ended  December  31,  2021  and  2020,  the  Company
determined that its goodwill was not impaired.

Revenue recognition

The Company derives revenues from (i) the sale of Unyvero Application cartridges, Unyvero Systems, SARS CoV-2 tests, Acuitas AMR Gene Panel test
products, (ii) providing laboratory services, (iii) providing collaboration services including funded software arrangements, and license arrangements, and
(iv) granting access to a small subset of the proprietary ARESdb data asset.

F-15

The Company analyzes contracts to determine the appropriate revenue recognition using the following steps: (i) identification of contracts with customers,
(ii) identification of distinct performance obligations in the contract, (iii) determination of contract transaction price, (iv) allocation of contract transaction
price to the performance obligations and (v) determination of revenue recognition based on timing of satisfaction of the performance obligation.

The  Company  recognizes  revenues  upon  the  satisfaction  of  its  performance  obligation  (upon  transfer  of  control  of  promised  goods  or  services  to  our
customers) in an amount that reflects the consideration to which it expects to be entitled in exchange for those goods or services.

The Company defers incremental costs of obtaining a customer contract and amortizes the deferred costs over the period that the goods and services are
transferred to the customer. The Company had no material incremental costs to obtain customer contracts in any period presented.

Deferred revenue results from amounts billed in advance to customers or cash received from customers in advance of services being provided.

Government grant agreements and research incentives

From  time  to  time,  the  Company  may  enter  into  arrangements  with  governmental  entities  for  the  purposes  of  obtaining  funding  for  research  and
development activities. The Company recognizes funding from grants and research incentives received European government agencies in the consolidated
statements of operations and comprehensive loss in the period during which the related qualifying expenses are incurred, provided that the conditions under
which the grants or incentives were provided have been met. For grants under funding agreements and for proceeds under research incentive programs, the
Company  recognizes  grant  and  incentive  income  in  an  amount  equal  to  the  estimated  qualifying  expenses  incurred  in  each  period  multiplied  by  the
applicable reimbursement percentage. The Company classifies government grants received under these arrangements as a reduction to the related research
and  development  expense  incurred.  The  Company  analyzes  each  arrangement  on  a  case-by-case  basis.  For  the  year  ended  December  31,  2021,  the
Company  recognized  $692,701  as  a  reduction  of  research  and  development  expense  related  to  government  grant  arrangements.  For  the  year  ended
December 31, 2020, the Company recognized $495,153 as a reduction of research and development expense related to government grant arrangements. As
of  December  31,  2021  and  2020,  the  Company  had  earned  but  not  yet  received  $396,365  and  $413,530,  respectively  related  to  these  agreements  and
incentives included in prepaid expenses and other current assets.

Research and development costs, net

Research and development costs are expensed as incurred. Research and development costs primarily consist of salaries and related expenses for personnel,
other resources, laboratory supplies, development materials, fees paid to consultants and outside service partners.

Stock-based compensation

Stock-based compensation expense is recognized at fair value. The fair value of stock-based compensation to employees and directors is estimated, on the
date of grant, using the Black-Scholes model. The resulting fair value is recognized ratably over the requisite service period, which is generally the vesting
period  of  the  option.  For  all  time-vesting  awards  granted,  expense  is  amortized  using  the  straight-line  attribution  method.  The  Company  accounts  for
forfeitures as they occur.

Option valuation models, including the Black-Scholes model, require the input of highly subjective assumptions, and changes in the assumptions used can
materially affect the grant-date fair value of an award. These assumptions include the risk-free rate of interest, expected dividend yield, expected volatility
and the expected life of the award. A discussion of management’s methodology for developing each of the assumptions used in the Black-Scholes model is
as follows:

Fair value of common stock

The Company uses the quoted market price of its common stock as its fair value.

F-16

Expected volatility

Through 2020, since OpGen did not have sufficient history to estimate the expected volatility of its common stock price, expected volatility was based on
the  volatility  of  peer  public  entities  that  were  similar  in  size  and  industry.  Beginning  in  2021,  for  stock  options  with  an  expected  term  where  there  is
sufficient history available, expected volatility is based on the volatility of OpGen's common stock.

Expected dividend yield

The Company has never declared or paid dividends on its common stock and has no plans to do so in the foreseeable future.

Risk-free interest rate

This is the U.S. Treasury rate for the day of each option grant during the year, having a term that most closely resembles the expected term of the option.

Expected term

This is the period of time that the options granted are expected to remain unexercised. Options granted have a maximum term of 10 years. The Company
estimates the expected term of the option to be 6.25 years for options with a standard four-year vesting period, using the simplified method. Over time,
management  will  track  actual  terms  of  the  options  and  adjust  their  estimate  accordingly  so  that  estimates  will  approximate  actual  behavior  for  similar
options.

Income taxes

Income  taxes  are  accounted  for  under  the  asset  and  liability  method.  Deferred  tax  assets  and  liabilities  are  recognized  for  the  expected  future  tax
consequences attributable to temporary differences between financial statement carrying amounts of existing assets and liabilities and their respective tax
basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary
differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the
period that includes the enactment date. A valuation allowance is established when necessary to reduce deferred income tax assets to the amount expected
to be realized.

Tax benefits are initially recognized in the financial statements when it is more likely than not the position will be sustained upon examination by the tax
authorities. Such tax positions are initially, and subsequently, measured as the largest amount of tax benefit that is greater than 50% likely of being realized
upon ultimate settlement with the tax authority, assuming full knowledge of the position and all relevant facts.

The  Company  had  federal  net  operating  loss  (“NOL”)  carryforwards  of  $202,015,062  and  $196,511,928  at  December  31,  2021  and  2020,  respectively.
Despite the NOL carryforwards, which begin to expire in 2022, the Company may have state tax requirements. Also, use of the NOL carryforwards may be
subject to an annual limitation as provided by Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”). To date, the Company has not
performed a formal study to determine if any of its remaining NOL and credit attributes might be further limited due to the ownership change rules of
Section  382  or  Section  383  of  the  Code.  The  Company  will  continue  to  monitor  this  matter  going  forward.  There  can  be  no  assurance  that  the  NOL
carryforwards will ever be fully utilized.

The Company also has foreign NOL carryforwards of $170,607,782 at December 31, 2021 from their foreign subsidiaries. $147,313,786 of those foreign
NOL  carryforwards  are  from  the  Company’s  operations  in  Germany.  Despite  the  NOL  carryforwards,  the  Company  may  have  a  current  and  future  tax
liability due to the nuances of German tax law around the use of NOL’s within a consolidated group. There is no assurance that the NOL carryforwards will
ever be fully utilized.

Loss per share

Basic  loss  per  share  is  computed  by  dividing  net  loss  available  to  common  stockholders  by  the  weighted  average  number  of  shares  of  common  stock
outstanding during the period.

F-17

For periods of net income, and when the effects are not anti-dilutive, diluted earnings per share is computed by dividing net income available to common
stockholders  by  the  weighted-average  number  of  shares  outstanding  plus  the  impact  of  all  potential  dilutive  common  shares,  consisting  primarily  of
common  stock  options  and  stock  purchase  warrants  using  the  treasury  stock  method,  and  convertible  preferred  stock  and  convertible  debt  using  the  if-
converted method.

For periods of net loss, diluted loss per share is calculated similarly to basic loss per share because the impact of all dilutive potential common shares is
anti-dilutive.  The  number  of  anti-dilutive  shares,  consisting  of  (i)  common  stock  options,  (ii)  stock  purchase  warrants,  and  (iii)  restricted  stock  units
representing the right to acquire shares of common stock which have been excluded from the computation of diluted loss per share, was 18.2 million shares
and 7.5 million shares as of December 31, 2021 and 2020, respectively.

Adopted accounting pronouncements

In  December  2019,  the  FASB  issued  ASU  No.  2019-12,  Simplifying the Accounting for Income Taxes, which  removes  certain  exceptions  related  to  the
approach for intra-period tax allocation, the methodology for calculating income taxes in an interim period, the recognition of deferred tax liabilities for
outside basis differences and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. The Company adopted ASU 2019-
12 on January 1, 2021. The impact of adopting ASU 2019-12 did not have a material impact on the Company’s consolidated financial statements.

In March 2020, the FASB issued ASU 2020-04, Reference  Rate  Reform  (Topic  848):  Facilitation  of  the  Effects  of  Reference Rate Reform  on  Financial
Reporting. The new guidance under ASU 2020-04 provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships and
other  transactions  affected  by  reference  rate  reform  if  certain  criteria  are  met.  The  amendments  apply  only  to  contracts  and  hedging  relationships  that
reference LIBOR or another reference rate expected to be discontinued due to reference rate reform. These amendments are effective immediately and may
be applied prospectively to contract modifications made and hedging relationships entered into or evaluated on or before December 31, 2022. The impact
of adopting ASU 2020-04 did not have a material impact on the Company’s consolidated financial statements.

Recently issued accounting standards

The Company has evaluated all other issued and unadopted ASUs and believes the adoption of these standards will not have a material impact on its results
of operations, financial position or cash flows.

Note 4 - Business Combination

On April 1, 2020, the Company completed its business combination transaction with Curetis N.V., a public company with limited liability under the laws of
the Netherlands, as contemplated by the Implementation Agreement, dated as of September 4, 2019, by and among the Company, the Seller, and Crystal
GmbH, a private limited liability company organized under the laws of the Federal Republic of Germany and wholly-owned subsidiary of the Company.
Pursuant to the Implementation Agreement, the Purchaser acquired all of the shares of Curetis GmbH, a private limited liability company organized under
the  laws  of  the  Federal  Republic  of  Germany,  and  certain  other  assets  and  liabilities  of  the  Seller,  as  further  described  below,  and  paid,  as  the  sole
consideration, 2,028,208 shares of the Company’s common stock, to the Seller, and reserved for future issuance (a) 134,356 shares of common stock, in
connection  with  its  assumption  of  the  Seller’s  2016  Stock  Option  Plan,  as  amended  (the  “Seller  Stock  Option  Plan”),  and  the  outstanding  awards
thereunder, and (b) 500,000 shares of common stock to be issued upon the conversion, if any, of certain convertible notes issued by the Seller.

At  the  closing,  the  Company  assumed  all  of  the  liabilities  of  the  Seller  solely  and  exclusively  related  to  the  acquired  business,  which  is  providing
innovative  solutions,  through  development  of  proprietary  platforms,  diagnostic  content,  applied  bioinformatics,  lab  services,  research  services  and
commercial collaborations and agreements, for molecular microbiology, diagnostics designed to address the global challenge of detecting severe infectious
diseases and identifying antibiotic resistances in hospitalized patients. Pursuant to the Implementation Agreement, the Company also assumed and adopted
the Seller Stock Option Plan as an Amended and Restated Stock Option Plan of the Company. In connection with the foregoing, the Company assumed all
awards thereunder that were outstanding as of the closing date and converted such awards into options to purchase shares of the Company’s common stock
pursuant to the terms of the applicable award. In addition, the Company assumed, at the closing, all of the outstanding convertible notes issued by the Seller
in favor of YA II PN, LTD, pursuant to the Assignment of the Agreement for the Issuance of and Subscription to Notes Convertible into Shares, dated
February 24, 2020, and entered into pursuant to the Implementation Agreement.

F-18

Curetis’  assets  and  liabilities  were  measured  and  recognized  at  their  fair  values  as  of  the  transaction  date  and  combined  with  the  assets,  liabilities  and
results of operations of OpGen after the consummation of the business combination. The allocation of the purchase price to acquired assets and assumed
liabilities based on their underlying fair values requires the extensive use of significant estimates and management’s judgment.

The components of the purchase price and net assets acquired are as follows:

Purchase Price

Number of shares issued to Curetis N.V
Multiplied by the market value per share of OpGen's common stock (i)
Total fair value of common stock issued to Curetis N.V shareholders

Fair value of replacement stock awards related to precombination service (ii)

    The price per share of OpGen’s common stock was based on the closing price as reported on the Nasdaq Capital Market on April 1, 2020.
    The fair value of the stock options assumed was determined using the Black-Scholes option pricing model.

To derive the fair value of the convertible notes, the Company estimated the fair value of the convertible notes with and without the derivative liability using a scenario
analysis and Monte Carlo simulation.

    The fair value of the EIB debt is determined using a discounted cash flow analysis with current applicable rates for similar instruments.

The fair value of identifiable intangible assets has been determined using the income approach, which involves significant unobservable inputs (Level 3
inputs).  These  inputs  include  projected  sales,  margin,  required  rate  of  return  and  tax  rate,  as  well  as  an  estimated  royalty  rate  in  the  case  of  the  trade
names/trademarks  intangibles.  The  trade  names/trademarks  intangibles  are  valued  using  a  relief-from-royalty  method.  The  customer/distributor
relationships are valued using the with and without method. The developed technology intangibles are valued using a multi-period earnings method.

The  Company  determined  the  fair  value  of  an  IPR&D  asset  resulting  from  the  acquisition  of  Curetis  using  the  multi-period  earnings  method  under  the
income  approach.  This  method  reflects  the  present  value  of  the  projected  cash  flows  that  are  expected  to  be  generated  by  the  IPR&D,  less  charges
representing the required return on other assets to sustain those cash flows.

The  weighted-average  amortization  periods  for  finite-lived  intangible  assets  acquired  are  15  years  for  customer/distributor  relationships,  10  years  for
developed technology and 10 years for trade names/trademarks.

The total consideration paid in the acquisition exceeded the estimated fair value of the tangible and identifiable intangible assets acquired and liabilities
assumed, resulting in approximately $6.7 million of goodwill. Goodwill, primarily related to expected synergies gained from combining operations, sales
growth  from  future  product  offerings  and  customers,  together  with  certain  intangible  assets  that  do  not  qualify  for  separate  recognition,  including
assembled workforce, is not tax deductible in all relevant taxing jurisdictions.

The  following  unaudited  pro  forma  financial  information  summarizes  the  results  of  operations  for  the  periods  indicated  as  if  the  Transaction  had  been
completed as of January 1, 2020. Pro forma information primarily reflects adjustments relating to the amortization of intangibles acquired and elimination
of  interest  expense  due  under  the  interim  facility.  The  pro  forma  amounts  do  not  purport  to  be  indicative  of  the  results  that  would  have  actually  been
obtained if the acquisition occurred as of January 1, 2020 or that may be obtained in the future.

The Company had approximately $0 and $18,000 of contract assets as of December 31, 2021 and 2020 respectively, which are generated when contractual
billing schedules differ from revenue recognition timing. Contract assets represent a conditional right to consideration for satisfied performance obligations
that becomes a billed receivable when the conditions are satisfied.

Unsatisfied performance obligations

The Company had no unsatisfied performance obligations related to its contracts with customers at December 31, 2021 and 2020.

Note 6 - Fair value measurements

The Company classifies its financial instruments using a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers
include:

• Level 1 - defined as observable inputs such as quoted prices in active markets;

• Level 2 - defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and

• Level 3 - defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions such

as expected revenue growth and discount factors applied to cash flow projections.

For the year ended December 31, 2021, the Company has not transferred any assets between fair value measurement levels.

Financial assets and liabilities measured at fair value on a recurring basis

The Company evaluates financial assets and liabilities subject to fair value measurements on a recurring basis to determine the appropriate level at which to
classify  them  each  reporting  period.  This  determination  requires  the  Company  to  make  subjective  judgments  as  to  the  significance  of  inputs  used  in
determining fair value and where such inputs lie within the hierarchy.

In June 2019, Curetis drew down a third tranche of EUR 5.0 million from the European Investment Bank (“EIB”). In return for EIB waiving the condition
precedent  of  a  minimum  cumulative  equity  capital  raised  of  EUR  15  million  to  disburse  this  EUR  5.0  million  tranche,  the  parties  agreed  on  a  2.1%
participation percentage interest (“PPI”). Upon maturity of the tranche, EIB would be entitled to an additional payment that is equity-linked and equivalent
to 2.1% of the then total valuation of Curetis N.V. On July 9, 2020, the Company negotiated an amendment to the EIB debt financing facility. As part of the
amendment, the parties adjusted the PPI percentage applicable to the previous EIB tranche of EUR 5.0 million which was funded in June 2019 from its
original 2.1% PPI in Curetis N.V.’s equity value upon maturity to a new 0.3% PPI in OpGen's equity value upon maturity between mid-2024 and mid-2025.
This right constitutes an embedded derivative, which is separated and measured at fair value with changes being accounted for through profit or loss. The
Company  determines  the  fair  value  of  the  derivative  using  a  Monte  Carlo  simulation  model.  Using  this  model,  level  3  unobservable  inputs  include
estimated discount rates and estimated risk-free interest rates.

The Company’s convertible debt with YA II PN, LTD (see Note 7) included a conversion feature which constitutes an embedded derivative, which was
separated and measured at fair value with subsequent changes being accounted for through profit or loss. The Company determines the fair value of the
derivative using a Monte Carlo simulation model. Using this model, level 3 unobservable inputs include estimated volatility rates and estimated risk-free
interest rates.

The fair value of level 3 liabilities measured at fair value on a recurring basis for the years ended December 31, 2021 and 2020 was as follows:

In July 2015, the Company entered into a Purchase Agreement with MGHIF, pursuant to which MGHIF purchased 2,273 shares of common stock of the
Company at $2,200 per share for gross proceeds of $5.0 million. Pursuant to the Purchase Agreement, the Company also issued to MGHIF an 8% Senior
Secured  Promissory  Note  (the  “MGHIF  Note”)  in  the  principal  amount  of  $1.0  million  with  a  two-year  maturity  date  from  the  date  of  issuance.  The
Company’s obligations under the MGHIF Note were secured by a lien on all of OpGen’s assets excluding the assets of Curetis GmbH, Curetis USA, and
Ares Genetics.

On June 28, 2017, the MGHIF Note was amended and restated, and the maturity date of the MGHIF Note was extended by one year to July 14, 2018. As
consideration  for  the  agreement  to  extend  the  maturity  date,  the  Company  issued  an  amended  and  restated  secured  promissory  note  to  MGHIF  that  (1)
increased  the  interest  rate  to  ten  percent  (10%)  per  annum  and  (2)  provided  for  the  issuance  of  common  stock  warrants  to  purchase  656  shares  of  its
common stock to MGHIF.

On June 11, 2018, the Company executed an Allonge to the MGHIF Note. The Allonge provided that accrued and unpaid interest of $285,512 due as of
July 14, 2018, the original maturity date, be paid through the issuance of shares of OpGen's common stock in a private placement transaction. In addition,
the Allonge revised and extended the maturity date for payment of the MGHIF Note to six semi-annual payments of $166,667 plus accrued and unpaid
interest beginning on January 2, 2019 and ending on July 1, 2021. The Allonge to the MGHIF Note was treated as a debt modification and, as such, the
unamortized issuance costs of approximately $7,000 as of June 11, 2018 were deferred and amortized as incremental expense over the term of the MGHIF
Note. During the year ended December 31, 2021, the Company made the final payment under the MGHIF Note and the lien on the Company’s assets was
released.

Yorkville Convertible Notes

The Company agreed to assume, as a condition to closing the business combination with Curetis all of the outstanding convertible notes (the “Convertible
Notes”) issued by Curetis N.V. in favor of YA II PN, LTD (“Yorkville”), pursuant to that certain Agreement for the Issuance of and Subscription to Notes
Convertible into Shares and Share Subscription Warrants, dated October 2, 2018, by and between Curetis N.V. and Yorkville.

On February 24, 2020, the Company entered into an Assignment of the Agreement for the Issuance of and Subscription to Notes Convertible into Shares
(the “Assignment Agreement”) with Curetis N.V. and Yorkville. Pursuant to the Assignment Agreement, upon assumption of the Convertible Notes by the
Company, the Convertible Notes ceased to be convertible into shares of Curetis N.V. and are instead convertible into shares of the Company’s common
stock, par value $0.01. The Assignment Agreement provided that an amount of 500,000 shares of the Company’s common stock that comprise a portion of
the consideration payable by the Company under the Implementation Agreement be reserved for issuance under the Convertible Notes. On June 17, 2020,
the Company registered for resale an additional 450,000 shares of Company common stock issuable upon conversion of the Convertible Notes.

F-23

 
 
 
 
 
At closing of the Transaction, an aggregate amount of €1.3 million of unconverted Convertible Notes was assumed by the Company. The Convertible Notes
were  measured  and  recognized  at  fair  value  at  the  acquisition  date.  The  fair  value  of  the  Convertible  Notes  as  of  the  closing  of  the  Transaction  was
approximately $1.3 million. The resulting debt discount was amortized over the life of the Convertible Notes as an increase in interest expense. During year
ended December 31, 2020, the Company issued 763,905 shares of common stock in satisfaction of approximately $1,451,000 of Convertible Notes. As of
December 31, 2020, all notes have been converted.

EIB Loan Facility

In 2016, Curetis entered into a contract for an up to €25 million senior, unsecured loan financing facility from the European Investment Bank (“EIB”). The
financing is in the first growth capital loan under the European Growth Finance Facility (“EGFF”), launched in November 2016. It is backed by a guarantee
from the European Fund for Strategic Investment (“EFSI”), EFSI is an essential pillar of the Investment Plan for Europe (“IPE”), under which the EIB and
the European Commission are working as strategic partners to support investments and bring back jobs and growth to Europe.

The funding can be drawn in up to five tranches within 36 months, under the EIB amendment, and each tranche is to be repaid upon maturity five years
after draw-down.

In April 2017, Curetis drew down a first tranche of €10 million from this facility. This tranche has a floating interest rate of EURIBOR plus 4% payable
after each 12-month-period from the draw-down-date and another additional 6% interest per annum that is deferred and payable at maturity together with
the principal. In June 2018, another tranche of €3 million was drawn down. The terms and conditions are analogous to the first one.

In June 2019, Curetis drew down a third tranche of €5 million from the EIB. In line with all prior tranches, the majority of interest is also deferred into the
bullet repayment structure upon maturity. In return for EIB waiving the condition precedent of a minimum cumulative equity capital raised of €15 million
to disburse this €5 million tranche, the parties agreed on a 2.1% PPI. Upon maturity of the tranche, not before approximately mid-2024 (and no later than
mid-2025) EIB would be entitled to an additional payment that is equity-linked and equivalent to 2.1% of the then total valuation of Curetis N.V. As part of
the amendment between the Company and EIB on July 9, 2020, the parties adjusted the PPI percentage applicable to the previous EIB tranche of €5 million
which was funded in June 2019 from its original 2.1% PPI in Curetis N.V.’s equity value upon maturity to a new 0.3% PPI in OpGen’s equity value upon
maturity. This right constitutes an embedded derivative, which is separated and measured at fair value with changes being accounted for through income or
loss.

On July 10, 2020, EIB agreed to defer total interest payments of €720k due in April and June 2020 under the first three tranches of the debt financing
facility until December 31, 2021. The Company made these interest payments in December 2020.

The EIB debt was measured and recognized at fair value as of the acquisition date. The fair value of the EIB debt was approximately $15.8 million as of the
acquisition date. The resulting debt discount will be amortized over the life of the EIB debt as an increase to interest expense.

As of December 31, 2021, the outstanding borrowings under all tranches were €22,216,012 (approximately USD $25,161,855), including deferred interest
payable at maturity of €4,216,012 (approximately USD $4,775,055).

PPP

On  April  22,  2020,  the  Company  entered  into  a  Term  Note  (the  “Company  Note”)  with  Silicon  Valley  Bank  (the  “Bank”)  pursuant  to  the  Paycheck
Protection  Program  (the  “PPP”)  of  the  Coronavirus  Aid,  Relief,  and  Economic  Security  Act  (“CARES  Act”)  administered  by  the  U.S.  Small  Business
Administration. The Company’s wholly-owned subsidiary, Curetis USA Inc. (“Curetis USA” and collectively with the Company, the “Borrowers”), also
entered into a Term Note with the Bank (the “Subsidiary Note,” and collectively with the Company Note, the “Notes”). The Notes were dated April 22,
2020. The principal amount of the Company Note was $879,630, and the principal amount of the Subsidiary Note was $259,353.

F-24

In accordance with the requirements of the CARES Act, the Borrowers will use the proceeds from the Notes in accordance with the requirements of the
PPP to cover certain qualified expenses, including payroll costs, rent and utility costs. Interest accrues on the Notes at the rate of 1.00% per annum. The
Borrowers may apply for forgiveness of amounts due under the Notes, in an amount equal to the sum of qualified expenses under the PPP, which include
payroll  costs,  rent  obligations,  and  covered  utility  payments  incurred  during  the  twenty-four  weeks  following  disbursement  under  the  Notes.  The  entire
proceeds were used under the Notes for such qualifying expenses. The Company Note was forgiven in November 2020. In May 2021, the Subsidiary Note
was forgiven.

Total interest expense (including accretion of fair value to face value and amortization of debt discounts and financing fees) on all debt instruments was
$4,799,331 and $3,399,984 for the years ended December 31, 2021 and 2020, respectively.

On November 25, 2020, the Company closed a private placement with one healthcare-focused U.S. institutional investor of (i) 2,245,400 shares of common
stock together with 2,245,400 common warrants to purchase up to 2,245,400 shares of common stock and (ii) 2,597,215 pre-funded warrants, with each
pre-funded warrant exercisable for one share of common stock, together with 2,597,215 common warrants to purchase up to 2,597,215 shares of common
stock (the “2020 PIPE”). Each share of common stock and accompanying common warrant were sold together at a combined offering price of $2.065, and
each pre-funded warrant and accompanying common warrant were sold together at a combined offering price of $2.055. The common warrants have an
exercise price of $1.94 per share, and are exercisable commencing on the six month anniversary of the date of issuance, and will expire five and one half
(5.5) years from the date of issuance. The 2020 PIPE raised aggregate net proceeds of $9.3 million, and gross proceeds of $10.0 million. As of December
31, 2020, all 2,597,215 pre-funded warrants issued in the 2020 PIPE have been exercised.

F-25

On February 11, 2021, the Company closed the February 2021 Offering with a single U.S.-based, healthcare-focused institutional investor for the purchase
of (i) 2,784,184 shares of common stock and (ii) 5,549,149 pre-funded warrants, with each pre-funded warrant exercisable for one share of common stock.
The Company also issued to the investor, in a concurrent private placement, unregistered common warrants to purchase 4,166,666 shares of the Company’s
common stock. Each share of common stock and accompanying common warrant were sold together at a combined offering price of $3.00, and each pre-

exercisable, at an exercise price of $0.01, and may be exercised at any time until all of the pre-funded warrants are exercised in full. The common warrants
will have an exercise price of $3.55 per share, will be exercisable commencing on the six-month anniversary of the date of issuance, and will expire five
and one-half (5.5) years from the date of issuance. The February 2021 Offering raised aggregate net proceeds of $23.5 million, and gross proceeds of $25.0
million. As of December 31, 2021, all pre-funded warrants issued in the February 2021 Offering have been exercised.

On March 9, 2021, the Company entered into an Exercise Agreement with the Holder from our 2020 PIPE financing. Pursuant to the Exercise Agreement,
in  order  to  induce  the  Holder  to  exercise  all  of  the  remaining  4,842,615  Existing  Warrants  for  cash,  pursuant  to  the  terms  of  and  subject  to  beneficial
ownership limitations contained in the Existing Warrants, the Company agreed to issue to the Holder, New Warrants to purchase 0.65 shares of common
stock for each share of common stock issued upon such exercise of the remaining Existing Warrants pursuant to the Exercise Agreement for an aggregate
of 3,147,700 New Warrants. The terms of the New Warrants are substantially similar to those of the Existing Warrants, except that the New Warrants have
an exercise price of $3.56. The New Warrants are immediately exercisable and will expire five years from the date of the Exercise Agreement. The Holder
paid an aggregate of $255,751 to the Company for the purchase of the New Warrants. The Company received aggregate gross proceeds before expenses of
approximately $9.65 million from the exercise of the remaining Existing Warrants held by the Holder and the payment of the purchase price for the New
Warrants. The Company recognized approximately $7.8 million of non-cash warrant inducement expense during year ended December 31, 2021 related to
this  transaction  representing  the  fair  value  of  the  New  Warrants  issued  to  induce  the  exercise.  The  fair  values  were  calculated  using  the  Black-Scholes
option pricing model.

On  October  18,  2021,  the  Company  closed  the  October  2021  Offering  with  a  single  healthcare-focused  institutional  investor  of  150,000  shares  of
convertible preferred stock and warrants to purchase up to an aggregate of 7,500,000 shares of common stock. The shares of preferred stock had a stated
value  of  $100  per  share  and  were  converted  into  an  aggregate  of  7,500,000  shares  of  common  stock  at  a  conversion  price  of  $2.00  per  share  after  the
Company received stockholder approval for an increase to its number of authorized shares of common stock, which approval occurred at the Company’s
special  meeting  of  stockholders  held  in  December  2021.  The  warrants  have  an  exercise  price  of  $2.05  per  share,  will  become  exercisable  six  months
following the date of issuance, and will expire five years following the initial exercise date. The warrants are classified as permanent equity at December
31,  2021.  In  connection  with  the  issuance  of  convertible  preferred  stock,  the  Company  recognized  a  beneficial  conversion  feature  of  $7,166,752  as  a
deemed dividend to the preferred stockholders.

On December 8, 2021, the Company received shareholder approval to increase the number of authorized shares of common stock of the Company. As of
December 31, 2021, all 150,000 shares of convertible preferred stock were converted into an aggregate of 7,500,000 shares of common stock. The October
2021 Offering raised aggregate net proceeds of $13.9 million, and gross proceeds of $15.0 million.

Stock options

In 2008, the Board adopted, and the stockholders approved, the 2008 Stock Option and Restricted Stock Plan (the “2008 Plan”), pursuant to which the
Company’s  Board  of  Directors  may  grant  either  incentive  or  non-qualified  stock  options  or  shares  of  restricted  stock  to  directors,  key  employees,
consultants and advisors.

In April 2015, the Board adopted, and the Company’s stockholders approved, the 2015 Equity Incentive Plan (the “2015 Plan”); the 2015 Plan became
effective upon the execution and delivery of the underwriting agreement for the Company’s IPO. Following the effectiveness of the 2015 Plan, no further
grants have been made under the 2008 Plan. The 2015 Plan provides for the granting of incentive stock options within the meaning of Section 422 of the
Code to employees and the granting of non-qualified stock options to employees, non-employee directors and consultants. The 2015 Plan also provides for
the  grants  of  restricted  stock,  restricted  stock  units,  stock  appreciation  rights,  dividend  equivalents  and  stock  payments  to  employees,  non-employee
directors and consultants.

F-26

Under  the  2015  Plan,  the  aggregate  number  of  shares  of  the  common  stock  authorized  for  issuance  may  not  exceed  (1)  2,710  plus  (2)  the  sum  of  the
number of shares subject to outstanding awards under the 2008 Plan as of the 2015 Plan’s effective date, that are subsequently forfeited or terminated for
any reason before being exercised or settled, plus (3) the number of shares subject to vesting restrictions under the 2008 Plan as of the 2015 Plan’s effective
date that are subsequently forfeited. In addition, the number of shares that have been authorized for issuance under the 2015 Plan will be automatically
increased on the first day of each fiscal year beginning on January 1, 2016 and ending on (and including) January 1, 2025, in an amount equal to the lesser
of (1) 4% of the outstanding shares of common stock on the last day of the immediately preceding fiscal year, or (2) another lesser amount determined by
the Company’s Board of Directors. Shares subject to awards granted under the 2015 Plan that are forfeited or terminated before being exercised or settled,
or are not delivered to the participant because such award is settled in cash, will again become available for issuance under the 2015 Plan. However, shares
that have actually been issued shall not again become available unless forfeited. As of December 31, 2021, 465,586 shares remain available for issuance
under the 2015 Plan.

On  September  30,  2020,  the  Company  held  its  2020  Annual  Meeting  of  Stockholders  (the  “2020  Annual  Meeting”).  At  the  2020  Annual  Meeting,
stockholders of the Company voted to approve, among other things, a plan under which stock options to purchase an aggregate of 1,300,000 shares of the
Company’s  common  stock  would  be  made  by  the  Board  of  Directors  of  the  Company  outside  of  the  stockholder-approved  equity  incentive  plan  to  its
executive  officers  and  non-employee  directors  (the  “2020  Stock  Options  Plan”).  The  2020  Stock  Options  Plan  and  the  grant  made  thereunder  were
approved by the Board of Directors on August 6, 2020, subject to receipt of stockholder approval at the 2020 Annual Meeting. The aggregate number of
shares  of  the  Company’s  common  stock  authorized  for  issuance  is  1,300,000  shares  of  common  stock  and  all  1,300,000  stock  options  were  issued  on
September 30, 2020. Shares subject to awards granted under the 2020 Stock Options Plan that are forfeited or terminated before being exercised will not be
available  for  re-issuance  under  the  2020  Stock  Options  Plan.  As  of  December  31,  2021,  no  shares  remain  available  for  issuance  under  the  2020  Stock
Options Plan.

Replacement awards

In  connection  with  the  business  combination  with  Curetis,  the  Company  issued  equity  awards  to  Curetis  employees  (“2016  Plan”),  consisting  of  stock
options (“replacement awards”) in exchange for their Curetis equity awards. The replacement awards consisted of 134,371 stock options with a weighted
average grant date fair value of $1.68. The terms of these replacement awards are substantially similar to the original Curetis equity awards. The fair value
of the replacement awards for services rendered through April 1, 2020, the acquisition date, was recognized as a component of the purchase consideration,
with the remaining fair value of the replacement awards related to the post-combination services recorded as stock-based compensation over the remaining
vesting period.

For the years ended December 31, 2021 and 2020, the Company recognized stock compensation expense as follows:

average period of 2.5 years.

At  December  31,  2021  and  2020,  the  Company  had  deferred  tax  assets  of  $106,839,267  and  $103,185,302,  respectively,  primarily  consisting  of  NOL
carryforwards, research and development (“R&D”) credits, and differences between depreciation and amortization recorded for financial statement and tax
purposes.  The  Company’s  net  deferred  tax  assets  at  December  31,  2021  and  2020  have  been  offset  by  a  valuation  allowance  of  $106,088,316  and
$98,874,420,  respectively.  The  valuation  allowance  has  been  recorded  due  to  the  uncertainty  of  realization  of  the  deferred  tax  assets.  The  Company’s
deferred tax assets and liabilities as of December 31, 2021 and 2020 are as follows:

Deferred tax assets:
NOL carryforward

The  difference  between  the  Company’s  expected  income  tax  provision  (benefit)  from  applying  federal  statutory  tax  rates  to  the  pre-tax  loss  and  actual
income tax provision (benefit) relates to the effect of the following:

Federal income tax benefit at statutory rates

Provision to return adjustment
State income tax benefit, net of federal benefit
Foreign rate differential
Change in valuation allowance

Management  followed  the  guidance  in  ASC  740,  which  states  that  “a  cumulative  loss  in  recent  years  is  a  significant  piece  of  negative  evidence  that  is
difficult to overcome” and concluded that the Company’s net deferred tax assets were not realizable as of December 31, 2021 and 2020. Accordingly, a
valuation allowance of $106.1 million and $98.9 million has been recorded to offset the net deferred tax assets.

The Company has federal NOL carryforwards of $202,015,062 and $196,511,928 at December 31, 2021 and 2020, respectively. The Company also has
total Foreign NOL carryforwards at December 31, 2021 of $170,607,782 which is primarily driven by the Company's operations in Germany. The NOL
carryforwards incurred prior to 2018 begin to expire in 2022. In December 2017, the U.S. government enacted comprehensive tax legislation commonly
referred to as the Tax Cuts and Jobs Act (the "Tax Act"), most of the provisions of which took effect starting in 2018. Under the Tax Act, the amount of
post  2017  NOLs  that  we  are  permitted  to  deduct  in  any  taxable  year  is  limited  to  80%  of  our  taxable  income  in  such  year,  where  taxable  income  is
determined without regard to the NOL deduction itself. In addition, the Tax Act generally eliminates the ability to carry back any NOL to prior taxable
years,  while  allowing  post  2017  unused  NOLs  to  be  carried  forward  indefinitely.  Utilization  of  the  NOL  carryforward  may  be  subject  to  an  annual
limitation as provided by Section 382 of the Code, defined earlier. There can be no assurance that the NOL carryforward will ever be fully utilized. To date,
the Company has not performed a formal study to determine if any of its remaining NOL and credit attributes might be further limited due to the ownership
change rules of Section 382 or Section 383 of the Code, as amended. The Company will continue to monitor this matter going forward. There can be no
assurance that the NOL carryforwards will ever be fully utilized.

On March 27, 2020, the United States enacted the CARES Act. The CARES Act is an emergency economic stimulus package that includes spending and
tax  breaks  to  strengthen  the  United  States  economy  and  fund  a  nationwide  effort  to  curtail  the  effect  of  COVID-19.  While  the  CARES  Act  provides
sweeping  tax  changes  in  response  to  the  COVID-19  pandemic,  some  of  the  more  significant  provisions  which  are  expected  to  impact  the  Company's
financial statements include removal of certain limitations on utilization of net operating losses, increasing the loss carryback period for certain losses to
five years, and increasing the ability to deduct interest expense, as well as amending certain provisions of the previously enacted Tax Cuts and Jobs Act.
The Company doesn't believe that the CARES Act will have a material impact on its financial position, results of operations, or cash flows.

Note 10 - Commitments and Contingencies

Registration and other stockholder rights

In connection with the various investment transactions, the Company entered into registration rights agreements with stockholders, pursuant to which the
investors  were  granted  certain  demand  registration  rights  and/or  piggyback  and/or  resale  registration  rights  in  connection  with  subsequent  registered
offerings of the Company’s common stock.

Supply agreements

In June 2017, the Company entered into an agreement with Life Technologies Corporation, a subsidiary of Thermo Fisher Scientific (“LTC”), to supply the
Company with Thermo Fisher Scientific’s QuantStudio 5 Real-Time PCR Systems (“QuantStudio 5”) to be used to run OpGen’s Acuitas AMR Gene Panel
tests.  Under  the  terms  of  the  agreement,  the  Company  must  notify  LTC  of  the  number  of  QuantStudio  5s  that  it  commits  to  purchase  in  the  following
quarter. As of December 31, 2021, the Company had acquired twenty-four QuantStudio 5s including none during the year ended December 31, 2021. As of
December 31, 2021, the Company has not committed to acquiring additional QuantStudio 5s in the next three months.

Curetis  places  frame-work  orders  for  Unyvero-Systems  and  for  raw  materials  for  its  cartridge  manufacturing  to  ensure  availability  during  commercial
ramp-up-phase  and  also  to  gain  volume-scale-effects  with  regards  to  purchase  prices.  Some  of  the  electronic  parts  used  for  the  production  of  Unyvero-
Systems have lead times of many months, hence it is necessary to order such systems with long-term framework-orders to ensure the demands from the
market are covered. The aggregate purchase commitments over the next twelve months are approximately $0.9 million.

COVID-19 Impact

In December 2019 and early 2020, the coronavirus known as COVID-19 was reported to have surfaced in China. The spread of this virus including its
variants and mutations globally in 2020 and 2021 as well as into 2022 has caused significant business disruption domestically in the United States and in
Europe, as well as China, the areas in which the Company primarily operates or has significant business interest. While the disruption is currently expected
to be temporary, such disruption is still ongoing and there remains considerable uncertainty around the duration of this disruption. Therefore, while the
Company expects that this matter will continue to impact the Company’s financial condition, results of operations, or cash flows, the extent of the financial
impact and duration cannot be reasonably estimated at this time.

Note 12 - License Agreements, Research Collaborations and Development Agreements

NYSDOH

In 2018, the Company announced a collaboration with the New York State Department of Health (“DOH”) and ILÚM Health Solutions, LLC (“ILÚM”), a
wholly-owned subsidiary of Merck’s Healthcare Services and Solutions division, to develop a state-of-the-art research program to detect, track, and manage
antimicrobial-resistant  infections  at  healthcare  institutions  statewide.  ILÚM  has  since  been  acquired  by  Infectious  Disease  Connect,  Inc.  (“IDC”),  a
University of Pittsburgh Medical Center (“UPMC”) Enterprise company. The Company is working together with DOH’s Wadsworth Center and IDC to
continue  development  of  an  infectious  disease  digital  health  and  precision  medicine  platform  that  connects  healthcare  institutions  to  DOH  and  uses
genomic microbiology for statewide surveillance and control of antimicrobial resistance. As part of the collaboration, the Company received approximately
$1.6 million over the 15-month demonstration portion of the project. The demonstration project began in early 2019 and was completed in the first quarter
of 2020. In April 2020, the Company began a second-year expansion phase to build on the successes and experience of the first-year pilot phase while
focusing  on  accomplishing  the  goal  of  the  effort  to  improve  patient  outcomes  and  save  healthcare  dollars  by  integrating  real-time  epidemiologic
surveillance  with  rapid  delivery  of  antibiotic  resistance  results  to  care-givers  via  web-based  and  mobile  platforms.  The  second-year  contract  included  a
quarterly retainer-based project fee as well as volume-dependent per test fees for a total contract value of up to $450,000 to OpGen. In April 2021, the
Company extended its second-year expansion phase by another six months through September 30, 2021 at which point the project was completed and has
ended. The six-month extension and expansion contract included a quarterly retainer-based project fee as well as volume-dependent per test fees for a total
contract value of up to an additional $540,000. During the years ended December 31, 2021 and 2020, the Company recognized $558,000 and $388,000 of
revenue related to the contract, respectively.

Sandoz

In  December  2018,  Ares  Genetics  entered  into  a  service  frame  agreement  with  Sandoz  International  GmbH  (“Sandoz”),  to  leverage  Ares  Genetics’
database on the genetics of antibiotic resistance, ARESdb, and the ARES Technology Platform for Sandoz’ anti-infective portfolio.

Under the terms of the frame agreement, which had an initial term of 36 months and recently been extended to end January 31, 2025, Ares Genetics and
Sandoz  intend  to  develop  a  digital  anti-infectives  platform,  combining  established  microbiology  laboratory  methods  with  advanced  bioinformatics  and
artificial intelligence methods to support drug development and life-cycle management. The collaboration, in the short- to mid-term, aims to both rapidly
and cost-effectively re-purpose existing antibiotics and design value-added medicines with the objective of expanding indication areas and to overcome
antibiotic resistance, in particular with regards to infections with bacteria that has already developed resistance against multiple treatment options. In the
longer-term, the platform is expected to enable surveillance for antimicrobial resistant pathogens to inform antimicrobial stewardship and the development
of novel anti-infectives that are less prone to encounter resistance and thereby preserve antibiotics as an effective treatment option.

F-33

The  agreement  covers  the  first  phases  of  the  collaboration  with  Sandoz  and  provides  certain  moderate  six-figure  R&D  funding  to  Ares  Genetics.  No
milestones or royalties were agreed to as part of this first phase of the collaboration. The agreement may be terminated by Sandoz effective immediately at
any time with written notice.

Qiagen

On February 18, 2019, Ares Genetics and Qiagen GmbH, or Qiagen, entered into a strategic licensing agreement for ARESdb and AREStools, in the area
of  antimicrobial  resistance  (“AMR”)  research.  The  agreement  has  a  term  of  20  years  and  may  be  terminated  by  Qiagen  for  convenience  with  180  days
written notice.

Ares Genetics has retained the rights to use ARESdb and AREStools for AMR research, customized bioinformatics services, and for the development of
specific  AMR  assays  and  applications  for  the  Curetis  Group  (including  Ares  Genetics),  as  well  as  third  parties  (e.g.,  other  diagnostics  companies  or
partners in the pharmaceutical industry). As the Qiagen research offering is expected to also enable advanced molecular diagnostic services and products,
Qiagen’s customers may obtain a diagnostic use license from Ares Genetics.

Under  the  terms  of  the  original  agreement,  Qiagen,  in  exchange  for  a  moderate  six  figure  up-front  licensing  payment,  has  received  an  exclusive  RUO
license to develop and commercialize general bioinformatics offerings and services for AMR research use only, based on Ares Genetics’ database on the
genetics  of  antimicrobial  resistance,  ARESdb,  as  well  as  on  the  ARES  bioinformatics  AMR  toolbox,  AREStools.  Under  the  agreement,  the  parties  had
agreed to a mid-single digit percentage royalty rate on Qiagen net sales, which is subject to a minimum royalty rate that steps up upon certain achieved
milestones, which is payable to Ares Genetics. The parties also agreed to further modest six figure milestone payments upon certain product launches. The
contract was subsequently amended in May 2021 to a non-exclusive license and a flat annual license fee as well as a royalty percentage on potential future
panel based products that are developed by Qiagen.

Global leading IVD corporation

On September 16, 2019, Ares Genetics entered into a multi-phase partnership with an undisclosed leading global in vitro diagnostics corporation, or the
Partner, to jointly develop diagnostic solutions for infectious disease testing, based on next-generation sequencing, or NGS, technology. Ares Genetics and
the  Partner  also  entered  into  an  R&D  option  agreement  for  the  first  phase  of  the  partnership.  Ares  Genetics  received  an  option  fee  of  approximately
$550,000.  The  initial  10-month  term  of  the  R&D  collaboration,  ended  July  13,  2020,  with  payments  excluding  the  option  fee  of  approximately  $1.2
million.

In the first phase of the collaboration, which lasted 10 months, the parties have further enriched ARESdb with a focus on certain pathogens relevant in a
first,  undisclosed  infectious  disease  indication.  Additional  clinical  isolates  of  such  pathogens  have  been  sequenced  by  Ares  Genetics  at  its  recently
established  NGS  laboratory  in  Vienna,  Austria.  Based  on  this  enlarged  and  enriched  dataset,  Ares  Genetics  has  further  developed  the  algorithms  for
predictive  antibiotic  resistance  testing  for  drug/pathogen  combinations  particularly  relevant  in  the  targeted  indication  to  enable  NGS-based  infectious
disease diagnostics.

Under the initial agreement, the Partner funded Ares Genetics’ R&D activities for the genotypic and phenotypic characterization of additional bacterial
strains to augment ARESdb and the development of optimized algorithms for predicting antibiotic resistance. Furthermore, in return for the up-front option
fee,  the  Partner  obtained  a  three-month  right  for  first  negotiation  for  an  exclusive  human  clinical  diagnostic  use  license  to  ARESdb  and  the  ARES
Technology Platform. A license was not executed and the collaboration ended in early 2021.

The  Company  recognized  approximately  $0  and  $870,000  of  revenue  related  to  the  contract  during  the  years  ended  December  31,  2021  and  2020,
respectively.

FISH License

The Company was party to one license agreement with Life Technologies to acquire certain patent rights and technologies related to its FISH product line.
Royalties were incurred upon the sale of a product or service which utilizes the licensed technology. The Company terminated this license agreement in
October 2020  effective  as  of  June  30,  2021  in  conjunction  with  its  announced  exit  of  the  FISH  business  in  June 2021.  The  Company  paid  a  one-time
settlement fee of $350,000 and paid a 10% royalty on the sale of eligible products through June 2021 but is no longer subject to any minimum royalty
obligations.  The  Company  recognized  net  royalty  expense  related  to  this  license  of  $11,721  and  $(68,854)  for  the  years  ended  December  31,  2021  and
2020, respectively.

Siemens

In  2016,  Ares  Genetics  acquired  the  GEAR  assets  from  Siemens  Technology  Accelerator  GmbH  (STA),  providing  the  original  foundation  to  ARESdb.
Under the agreement with STA, Ares Genetics incurs royalties on revenues from licensed product sales or sublicensing proceeds. Royalty rates under the
Siemens agreement range from 1.3% to 40% depending on the specifics of the licenses and rights provided by Ares Genetics to third parties and whether
such third parties may have been originally introduced by Siemens to Ares Genetics. The total net royalty expense related to this agreement was $146,375
and $2,775 for the years ended December 31, 2021 and 2020, respectively.

Note 13 - Related Party Transactions

On  April  1,  2020,  as  part  of  the  Transaction,  Oliver  Schacht,  Ph.D.,  the  former  CEO  of  Curetis  N.V.,  was  appointed  as  the  CEO  of  the  Company,  and
Johannes Bacher the former COO of Curetis N.V. was appointed as the COO of the Company. Effective April 1, 2020, Mr. Schacht and Mr. Bacher were
appointed as liquidators of Curetis N.V. in liquidation and Curetis GmbH was designated as Custodian of the Books for Curetis N.V. During a portion of
the year ended December 31, 2020, Curetis N.V. in liquidation processed payroll for Mr. Schacht and Mr. Bacher and invoiced OpGen and Curetis GmbH,
respectively, in line with their signed management agreements.

Exhibit 4.19

DESCRIPTION OF THE REGISTRANT’S SECURITIES

REGISTERED PURSUANT TO SECTION 12 OF THE SECURITIES EXCHANGE ACT OF 1934

The following description sets forth certain material terms and provisions of the securities of OpGen Inc. (the “Company,” “we,” “us” and “our”)
that are registered under Section 12 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). This description also summarizes relevant
provisions of Delaware General Corporation Law (the “DGCL”). The following summary does not purport to be complete and is subject to, and is qualified
in its entirety by reference to, the applicable provisions of the DGCL and our certificate of incorporation and our by-laws, copies of which are incorporated
by  reference  as  an  exhibit  to  the  Annual  Report  on  Form  10-K  of  which  this  Exhibit  4.13  is  a  part.  We  encourage  you  to  read  our  certificate  of
incorporation, our by-laws and the applicable provisions of the DGCL for additional information.

Our common stock, par value $0.01 per share, trading symbol OPGN is registered under Section 12(b) of the Exchange Act.

Authorized Capital Stock

As  of  December  31,  2021,  our  authorized  capital  stock  consists  of  100,000,000  shares  of  common  stock,  par  value  $0.01  per  share,  and
10,000,000  shares  of  preferred  stock,  par  value  $0.01  per    share,  of  which  10,000,000  shares  are  available  for  future  issuance.  As  of  March  25,  2022,
46,557,750 shares of our common stock are issued and outstanding.

Common Stock

The holders of our common stock are entitled to one vote for each share held on all matters submitted to a vote of the stockholders. The holders of
our common stock do not have any cumulative voting rights. The Board of Directors are elected to a one year term; the Company does not have a staggered
board. Holders of our common stock are entitled to receive ratably any dividends declared by the Board of Directors out of funds legally available for that
purpose, subject to any preferential dividend rights of any outstanding preferred stock. Our common stock has no preemptive rights, conversion rights or
other subscription rights or redemption or sinking fund provisions.

In the event of our liquidation, dissolution or winding up, holders of our common stock will be entitled to share ratably in all assets remaining

after payment of all debts and other liabilities and any liquidation preference of any outstanding preferred stock.

Anti-Takeover Effects of Our Certificate of Incorporation, Bylaws and Delaware Law

Our certificate of incorporation and bylaws include a number of provisions that may have the effect of delaying, deferring or preventing another
party from acquiring control of us and encouraging persons considering unsolicited tender offers or other unilateral takeover proposals to negotiate with our
board of directors rather than pursue non-negotiated takeover attempts. These provisions include the items described below.

Meetings of Stockholders

Our certificate of incorporation and bylaws provide that only the Chair of the Board, the Chief Executive Officer or a majority of the members of
our board of directors then in office may call special meetings of stockholders and only those matters set forth in the notice of the special meeting may be
considered or acted upon at a special meeting of stockholders. Our bylaws limit the business that may be conducted at an annual meeting of stockholders to
those matters properly brought before the meeting.

Advance Notice Requirements

Our  bylaws  establish  advance  notice  procedures  with  regard  to  stockholder  proposals  relating  to  the  nomination  of  candidates  for  election  as
directors or new business to be brought before meetings of our stockholders. These procedures provide that notice of stockholder proposals must be timely
given in writing to our corporate secretary prior to the meeting at which the action is to be taken. Generally, to be timely, notice must be received at our
principal executive offices not less than 90 days nor more than 120 days prior to the first anniversary date of the annual meeting for the preceding year. Our
bylaws specify the requirements as to form and content of all stockholders’ notices. These requirements may preclude stockholders from bringing matters
before the stockholders at an annual or special meeting.

 
 
 
 
Amendment to Certificate of Incorporation and Bylaws

Any amendment of our certificate of incorporation must first be approved by a majority of our board of directors, and if required by law or our
certificate of incorporation, must thereafter be approved by a majority of the outstanding shares entitled to vote on the amendment. Our bylaws may be
amended by the affirmative vote of a majority of the directors then in office, subject to any limitations set forth in the bylaws; and may also be amended by
the  affirmative  vote  of  at  least  66  2/3%  of  the  outstanding  shares  entitled  to  vote  on  the  amendment,  or,  if  our  board  of  directors  recommends  that  the
stockholders approve the amendment, by the affirmative vote of the majority of the outstanding shares entitled to vote on the amendment, in each case
voting together as a single class.

Undesignated Preferred Stock

Our board of directors has the authority, without further action by our stockholders, to issue from time to time 10,000,000 shares of preferred stock
in  one  or  more  series.  The  existence  of  authorized  but  unissued  shares  of  preferred  stock  may  enable  our  board  of  directors  to  discourage  an  attempt
to  obtain control of us by means of a merger, tender offer, proxy contest or otherwise. For example, if in the due exercise of its fiduciary obligations, our
board of directors were to determine that a takeover proposal is not in the best interests of our stockholders, our board of directors could cause shares of
preferred stock to be issued without stockholder approval in one or more private offerings or other transactions that might dilute the voting or other rights
of the proposed acquirer or insurgent stockholder or stockholder group. In this regard, our certificate of incorporation grants our board of directors broad
power to establish the rights and preferences of authorized and unissued shares of preferred stock. The issuance of shares of preferred stock could decrease
the amount of earnings and assets available for distribution to holders of shares of common stock. The issuance may also adversely affect the rights and
powers, including voting rights, of these holders and may have the effect of delaying, deterring or preventing a change in control of us.

Exclusive Jurisdiction for Certain Actions

Our certificate of incorporation provides that, once our common stock is a “covered security,” unless we consent in writing to the selection of an
alternative forum, the Court of Chancery of the State of Delaware shall be the sole and exclusive forum for (i) any derivative action or proceeding brought
on  our  behalf,  (ii)  any  action  asserting  a  claim  of  breach  of  a  fiduciary  duty  owed  by  any  of  our  directors,  officers  or  other  employees  to  us  or  our
stockholders, (iii) any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law, our certificate of incorporation
or our bylaws, or (iv) any action asserting a claim against us governed by the internal affairs doctrine. Although we believe this provision benefits us by
providing  increased  consistency  in  the  application  of  Delaware  law  in  the  types  of  lawsuits  to  which  it  applies,  the  provision  may  have  the  effect  of
discouraging  lawsuits  against  our  directors  and  officers.  The  enforceability  of  similar  exclusive  forum  provisions  in  other  companies’  certificates  of
incorporation has been challenged in legal proceedings, and it is possible that a court could rule that this provision in our certificate of incorporation is
inapplicable or unenforceable. In addition, this exclusive forum provision is intended to apply to claims arising under Delaware state law and would not
apply to claims brought pursuant to the Securities Act or the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction. To
the extent the provision could be construed to apply to such claims, there is uncertainty as to whether a court would enforce the provision in such respect,
and our stockholders will not be deemed to have waived compliance with federal securities laws and the rules and regulations thereunder. 

 
 
 
Section 203 of the Delaware General Corporation Law

We are subject to the provisions of Section 203 of the Delaware General Corporation Law. In general, Section 203 prohibits a publicly held
Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a three-year period following the time that this
stockholder becomes an interested stockholder, unless the business combination is approved in a prescribed manner. Under Section 203, a business
combination between a corporation and an interested stockholder is prohibited unless it satisfies one of the following conditions:

·

·

·

before the stockholder became interested, our board of directors approved either the business combination or the transaction which resulted in
the stockholder becoming an interested stockholder;

upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the interested stockholder owned
at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining
the voting stock outstanding, shares owned by persons who are directors and also officers, and employee stock plans, in some instances, but
not the outstanding voting stock owned by the interested stockholder; or

at or after the time the stockholder became interested, the business combination was approved by our board of directors and authorized at an
annual or special meeting of the stockholders by the affirmative vote of at least two-thirds of the outstanding voting stock which is not owned
by the interested stockholder.

Section 203 defines a business combination to include:

·

·

·

·

·

any merger or consolidation involving the corporation and the interested stockholder;

any sale, transfer, lease, pledge or other disposition involving the interested stockholder of 10% or more of the assets of the corporation;

subject to exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested
stockholder;

subject to exceptions, any transaction involving the corporation that has the effect of increasing the proportionate share of the stock of any
class or series of the corporation beneficially owned by the interested stockholder; and

the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits provided by or
through the corporation.

In general, Section 203 defines an interested stockholder as any entity or person beneficially owning 15% or more of the outstanding voting stock

of the corporation and any entity or person affiliated with or controlling or controlled by the entity or person.
