Section 27A of the Securities Act of 1933, as amended (the “Securities Act”) and Section 21E of the Securities Exchange Act of 1934, as amended (the
“Exchange Act”). In this Annual Report, we refer to OpGen, Inc. as the “Company,” “OpGen,” “we,” “our” or “us.” All statements, other than statements
of  historical  facts  contained  herein,  including  statements  regarding  our  future  results  of  operations  and  financial  position,  strategy  and  plans,  and  our
expectations  for  future  operations,  are  forward-looking  statements.  The  words  “believe,”  “may,”  “will,”  “estimate,”  “continue,”  “anticipate,”  “design,”
“intend,” “expect” or the negative version of these words and similar expressions are intended to identify forward-looking statements.

We have based these forward-looking statements on our current expectations and projections about future events and trends that we believe may affect our
financial  condition,  results  of  operations,  strategy,  short-  and  long-term  business  operations  and  objectives,  and  financial  needs.  These  forward-looking
statements are subject to a number of risks, uncertainties and assumptions, including those described in Part I, Item 1A “Risk Factors.” In light of these
risks, uncertainties and assumptions, the forward-looking events and circumstances included herein may not occur, and actual results could differ materially
and adversely from those anticipated or implied in the forward-looking statements. Given these uncertainties, you should not place undue reliance on these
forward-looking statements. Forward-looking statements include, but are not limited to, statements about:

● our liquidity and working capital requirements, including our cash requirements over the next 12 months;

● our ability to maintain compliance with the ongoing listing requirements for the Nasdaq Capital Market;

● our ability to execute upon and achieve the benefits of the strategic direction under the Company’s new leadership and Board;

● our ability to identify and realize the benefits of potential strategic transactions;

● adverse effects on our business condition and results of operations from general economic and market conditions and overall fluctuations in the

United States and international markets, including deteriorating market conditions due to investor concerns regarding inflation;

● our use of proceeds from capital financing transactions;

● compliance with the U.S. regulations applicable to our business; and

● our expectations regarding future revenue and expenses.

Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, level of activity,
performance  or  achievements.  In  addition,  neither  we  nor  any  other  person  assumes  responsibility  for  the  accuracy  and  completeness  of  any  of  these
forward-looking statements. Any forward-looking statement made by us in this Annual Report speaks only as of the date on which it is made. We disclaim
any duty to update any of these forward-looking statements after the date of this Annual Report to confirm these statements to actual results or revised
expectations.

These  factors  should  not  be  construed  as  exhaustive  and  should  be  read  in  conjunction  with  our  other  disclosures,  including  but  not  limited  to  the  risk
factors described in Part I, Item 1A of this Annual Report. Other risks may be described from time to time in our filings made under the securities laws.
New risks emerge from time to time. It is not possible for our management to predict all risks. All forward-looking statements in this Annual Report speak
only  as  of  the  date  made  and  are  based  on  our  current  beliefs  and  expectations.  We  undertake  no  obligation  to  update  or  revise  any  forward-looking
statement, whether as a result of new information, future events or otherwise.

Item 1. Business

PART I

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.  (“OpGen”  or  the  “Company”)  was  incorporated  in  Delaware  in  2001.  On  April  1,  2020,  OpGen  completed  its  business  combination
transaction with Curetis N.V., a public company with limited liability under the laws of the Netherlands. As part of the transaction, the Company acquired
all the shares of Curetis GmbH, a private limited liability company organized under the laws of the Federal Republic of Germany (“Curetis”), and certain
other assets and liabilities of Curetis GmbH, including all its shares of Ares Genetics GmbH (“Ares Genetics”). From inception through November 2023,
the Company operated as a precision medicine company harnessing the power of molecular diagnostics and informatics to help combat infectious disease.
The Company, along with its subsidiaries, Curetis and Ares Genetics, developed and commercialized 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.

During the year ended December 31, 2023, the Company implemented certain cash management initiatives, including restructuring its U.S. operations by
reducing headcount from 24 to 5 and has since continued scaling down operations at OpGen’s U.S. headquarters to the core functions of a U.S. Nasdaq
listed company with only minimal distribution, marketing, and sales support, allowing the Company to conserve cash and focus on the functions needed to
pursue potential strategic alternatives. However, on November 6, 2023, Curetis filed a petition for insolvency with the district court of Stuttgart, Germany,
and Ares Genetics filed a petition for insolvency with the commercial court in Vienna, Austria. The insolvency proceedings of Curetis and Ares Genetics
were adjudicated under the insolvency laws of Germany and Austria, respectively.

The insolvency administrators assumed control over the assets and liabilities of Curetis and Ares Genetics, respectively, which eliminated the authority and
power of the Company and its officers to act on behalf of the subsidiaries. The loss of control required that the Company no longer include Curetis and
Ares  Genetics  in  its  consolidated  financial  statements.  Prior  to  the  insolvency  filings,  Curetis  and  Ares  Genetics  had  been  included  in  the  Company’s
consolidated financial statements. Upon deconsolidation of Curetis and Ares Genetics, the Company recognized gains on deconsolidation of subsidiaries at
the subsidiary levels of $46.6 million for Curetis and $7.7 million for Ares Genetics, which was offset by a loss on deconsolidation of subsidiary for the
Company  of  $67.3  million.  The  deconsolidation  charges  to  operations  represent  the  excess  of  the  carrying  value  over  the  fair  value  of  the  Company’s
interest in and intercompany payables to and receivables from Curetis and Ares Genetics as of the insolvency filing date.

Since  the  insolvency  filings  and  through  the  three  months  ended  March  31,  2024,  the  Company  continues  to  sell  the  Curetis  Unyvero  products  to  its
existing customers in the United States via drop shipments from Curetis directly to customer locations. The Unyvero tests are 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. As of December 31, 2023, OpGen had an installed base of approximately 28 Unyvero A50 Analyzers
across  the  United  States  in  different  types  of  hospitals  and  laboratories,  including  installations  for  clinical  studies.  The  sale  of  Ares  Genetics’  related
products and services was discontinued during the first quarter of 2024 due to the sale of the Ares Genetics assets to a strategic acquiror by its insolvency
administrator in Austria.

In March 2024, the Company entered into a securities purchase agreement (the “March 2024 Purchase Agreement”) with David E. Lazar, pursuant to which
the Company agreed to sell 3,000,000 shares of Series E Convertible Preferred Stock (“Series E Preferred Stock”) to Mr. Lazar at a price of $1.00 per share
for aggregate gross proceeds of $3.0 million (the “March 2024 Private Placement”). In connection with the transactions contemplated by the March 2024
Purchase  Agreement,  the  members  of  the  Board  of  Directors,  prior  to  the  closing  of  such  transactions,  resigned  and  a  new  Board  of  Directors  was
appointed, of which Mr. Lazar was appointed Chairman. The focus of OpGen going forward, under new leadership and a new Board of Directors, will be
on the identification of a privately held company to complete a reverse merger or similar strategic transaction.

On January 5, 2023, the Company effected a reverse stock split of its issued and outstanding shares of common stock at a ratio of 1 post-reverse-split share
for  every  20  pre-reverse-split  shares.  The  common  stock  continues  to  be  traded  on  The  Nasdaq  Capital  Market  under  the  symbol  “OPGN”  and  began
trading on a split-adjusted basis on January 5, 2023. All share amounts and per share prices in this Annual Report have been adjusted to reflect the reverse
stock split.

On May 9, 2024, the Company held a special meeting of stockholders to vote on certain matters, including the removal of certain restrictions applicable to
the voting of Mr. Lazar’s shares of Series E Preferred Stock. Following approval of the proposals at such special meeting, subject to limited exceptions,
Mr. Lazar may vote his shares without restrictions.

On May 20, 2024, the Company effected a reverse stock split of its issued and outstanding shares of common stock at a ratio of 1 post-reverse-split share
for  every  10  pre-reverse-split  shares.  The  common  stock  continues  to  be  traded  on  The  Nasdaq  Capital  Market  under  the  symbol  “OPGN”  and  began
trading on a split-adjusted basis on May 20, 2024. All share amounts and per share prices in this Annual Report have been adjusted to reflect the reverse
stock split.

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,  may  also  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.

Risks Related to Our Business

We have only a modest amount of cash, which is not sufficient to support our plan of operations for the long-term.

We have obtained short-term financing as a result of the March 2024 Private Placement; however, such financing provided the Company limited capital and
there can be no assurance that additional financing will be available to us, or if available, will be on terms satisfactory to us in the longer-term. If we are
unable to obtain funds when we need them or if we cannot obtain funds on terms favorable to us within the longer-term, we may not be able to maintain our
operations as a going concern.

We scaled down operations, will not generate significant revenues unless we complete a business combination with an operating company, and need
additional capital to fund our activities.

We continue to implement cash management initiatives, included scaled down operations to the core functions of a U.S. Nasdaq listed company with only
minimal distribution, marketing, and sales support, allowing the Company to conserve cash and focus on the functions needed to pursue potential strategic
alternatives. As we have transitioned our business model, unless we complete a business combination with an operating company, we will not generate
significant new revenues in the future and we will continue to incur expenses related to identifying and acquiring an operating company and compliance
with  our  reporting  obligations  under  applicable  federal  securities  laws.  We  will  need  to  raise  additional  funds,  and  such  funds  may  not  be  available  on
commercially acceptable terms, if at all. If we cannot raise funds on acceptable terms, we may not be able to continue to execute our plan to acquire an
operating company and in the extreme case, we may need to liquidate the Company.

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, 2023 and 2022 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, 2023 and 2022, we had net losses of $32.7 million and $37.3 million, respectively. From our inception through December 31, 2023, we had
an accumulated deficit of $305.5 million. The reports of our independent registered public accounting firm on our financial statements for the years ended
December  31,  2023  and  2022  each  contain  explanatory  language  that  substantial  doubt  exists  about  our  ability  to  continue  as  a  going  concern.  We
completed a number of financings in 2022 and 2023. We completed an at-the-market offering which raised net proceeds of approximately $0.99 million in
2022,  a  registered  direct  financing  in  October  2022,  which  raised  net  proceeds  of  approximately  $3.04  million,  a  registered  direct  financing  in
January  2023,  which  raised  net  proceeds  of  approximately  $6.9  million,  a  best-efforts  public  offering  in  May  2023,  which  raised  net  proceeds  of
approximately $3.0 million, a preferred stock purchase agreement in October 2023 for up to $1.0 million in proceeds, and a warrant inducement agreement
in October 2023, which raised net proceeds of $2.057 million. Additionally, we entered into a securities purchase agreement for the sale of preferred stock
in March 2024, which is expected to raise proceeds of approximately $3.0 million. We cannot assure you that we can continue to raise the capital necessary
to fund our business. Failure to achieve profitable operations may require us to seek additional financing when none is available or is only available on
unfavorable terms.

3

 
 
 
 
 
 
 
 
 
 
 
We have substantial amount of debt which must be liquidated prior to entering an acquisition of an operating company.

We have made significant progress in negotiating our debt with our creditors. As part of the March 2024 Purchase Agreement, the Company entered into
settlement agreements (the “Settlement Agreements”) with each of the European Investment Bank (“EIB”) and Curetis GmbH, the Company’s subsidiary
(“Curetis”),  and  Curetis’  trustee  in  insolvency,  pursuant  to  which  the  parties  agreed  to  settle  outstanding  liabilities  amongst  the  parties.  Pursuant  to  the
settlement  agreements  and  March  2024  Purchase  Agreement,  following  the  final  closing  of  the  transactions  contemplated  by  the  March  2024  Purchase
Agreement, the Company will pay $2.0 million of the proceeds to settle all outstanding debt of the Company to each of EIB and Curetis. The settlement
agreement with EIB also terminated that certain Guarantee and Indemnity Agreement, dated as of July 9, 2020, by and between the EIB and the Company,
pursuant to which the Company had guaranteed all of Curetis’ debt to EIB. If we are unable to pay and settle such outstanding liabilities in accordance with
the terms of the settlement agreements, the Company will continue to have substantial debt to the EIB, and we will not have capital to pay such debt in
accordance with its terms, which would have a material adverse effect and, if the EIB exercises its rights and remedies under our guarantee agreement,
would likely force us to seek bankruptcy protection.

We may not be able to acquire an operating company and if we complete such an acquisition, we expect that we will need to raise additional capital.

Assuming we transition our business model as expected, our sole business objective, following liquidation of our debts, will be to seek to identify strategic
opportunities. As of the date of this report, we have commenced the process of identifying strategic opportunities, but there can be no assurance that we
will be able to complete such a transaction.

In the event we complete such a transaction, we expect that we will need to raise substantial additional capital. We intend to rely on external sources of
financing to meet any capital requirements and to obtain such funding through the debt and equity markets. We cannot provide any assurances that we will
be able to obtain additional funding when it is required or that it will be available to us on commercially acceptable terms, if at all. If we fail to obtain such
necessary funding, any such transaction may not be successful.

Our  Board  of  Directors  has  sole  discretion  to  identify  and  evaluate  transaction  candidates  and  complete  transactions  without  the  approval  of  our
stockholders.

We  have  not  developed  any  specific  transaction  guidelines  and  we  are  not  obligated  to  follow  any  particular  operating,  financial,  geographic  or  other
criteria  in  evaluating  candidates  for  potential  transactions  or  business  combinations.  We  will  target  companies  that  we  believe  will  provide  the  best
potential  long-term  financial  return  for  our  stockholders  and  we  will  determine  the  purchase  price  and  other  terms  and  conditions  of  such  transactions
without review or approval of our stockholders. Accordingly, our stockholders will not have the opportunity to evaluate the relevant economic, financial,
and other information that our Board will use and consider in deciding whether or not to enter into a particular transaction.

We will not generate any significant revenue or earnings in the near future unless and until we merge with or acquire an operating business.

Upon settlement of our debts to EIB, if such an event occurs, we will have limited assets and operations. As a result, we do not expect to generate any
significant revenue or realize significant revenue unless and until we successfully complete a strategic transaction.

There is competition for those private companies suitable for a merger transaction of the type being contemplated by management.

There  is  currently  a  very  competitive  market  for  business  opportunities,  which  could  reduce  the  likelihood  of  consummating  a  successful  business
combination. We expect to be an insignificant participant in the business of seeking mergers with, joint ventures with, and acquisitions of small private and
public  entities.  A  large  number  of  established  and  well-financed  entities,  including  small  public  companies,  venture  capital  firms,  and  special  purpose
acquisition companies, or “SPACs”, are active in mergers and acquisitions of companies that may be desirable target candidates for us. Nearly all these
entities  have  significantly  greater  financial  resources,  technical  expertise  and  managerial  capabilities  than  we  do.  As  a  result,  we  may  be  unable  to
effectively  compete  with  such  entities  in  identifying  possible  business  opportunities  and  successfully  completing  a  business  combination.  These
competitive factors may reduce the likelihood of us identifying and consummating a successful business combination.

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, ransomware attacks or
other  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, as described above.

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 Health Insurance Portability and
Accountability Act, or HIPAA, and regulatory penalties. Unauthorized access, loss or dissemination could also disrupt our operations, including our ability
to collect, process, and prepare Company financial information as well as manage the administrative aspects of our business, all of which could adversely
affect our business.

In addition, the interpretation and application of consumer, health-related, privacy and data protection laws in the United States 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.

We are subject to risks with respect to counterparties, and failure of such counterparties to meet their obligations could cause us to suffer losses or
negatively impact our results of operations and cash flows.

We have entered into various contracts that are material to the operation of our business that subject us to counterparty risks. The ability and willingness of
our counterparties to perform their obligations under any contract will depend on a number of factors that are beyond our control and may include, among
other  things,  general  economic  conditions,  the  condition  of  such  counterparty’s  industry  and  the  overall  financial  condition  of  the  counterparty.  A
prolonged period of difficult industry conditions could lead to changes in a counterparty’s liquidity and increase our exposure to counterparty risk. If our
counterparties are unable or unwilling to perform, it could negatively impact our results of operations and cash flows.

Risks Related to Our Securities and Public Company Status

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.

We  cannot  assure  you  that  we  will  be  able  to  continue  to  comply  with  the  Nasdaq  Minimum  Bid  Price  Rule,  the  Periodic  Filing  Rule,  or  other
continued  listing  standards  of  the  Nasdaq  Capital  Market.  If  we  are  unable  to  maintain  compliance  with  such  standards,  we  could  be  subject  to
delisting or other adverse action, which could negatively impact the trading of our common stock.

As  previously  disclosed,  we  requested  a  hearing  by  the  Nasdaq  Hearings  Panel  of  The  Nasdaq  Stock  Market  LLC  to  appeal  the  Nasdaq  listing  staff’s
determination  to  delist  the  Company’s  securities  as  a  result  of  the  failure  of  the  Company’s  common  stock  to  comply  with  the  minimum  bid  price
requirement of Nasdaq Listing Rule 5550(a)(2). In response to the Company’s request, on February 9, 2024, the Company received written notification
from Nasdaq notifying the Company that the Panel had granted the Company’s request for an additional period, during which the Company will remain
listed on Nasdaq, to regain compliance with the Bid Price Rule. Pursuant to the Notice, the Panel granted the Company an additional period until June 3,
2024 to regain compliance. The extension is subject to certain conditions specified by the Panel in the Notice. Thereafter, Nasdaq notified the Company
that it failed to comply with Nasdaq Listing Rule 5250(c)(1) for failing to timely file this Annual Report and the Company’s Quarterly Report on Form 10-
Q  for  the  three-month  period  ended  March  31,  2024.  The  Panel  again  granted  the  Company’s  request  for  additional  time  to  cure  such  delinquencies,
provided that the Company file this Annual Report by June 3, 2024 and the Quarterly Report on Form 10-Q by July 8, 2024.

While  the  Company  intends  to  comply  with  such  conditions  and  rules,  there  can  be  no  assurance  that  the  Company  will  be  able  to  regain  or  remain  in
compliance  with  the  applicable  Nasdaq  listing  requirements  on  an  ongoing  basis  or  that  the  Panel  will  afford  the  Company  additional  time  to  achieve
compliance. If we are unable to satisfy these requirements or standards, we could be subject to delisting, which would have a negative effect on the price of
our common stock and would impair your ability to sell or purchase our common stock when you wish to do so.

The 2024 Reverse Stock Split may decrease the liquidity of the shares of our common stock.

The  liquidity  of  the  shares  of  our  common  stock  may  be  affected  adversely  by  the  2024  Reverse  Stock  Split  given  the  reduced  number  of  shares
outstanding after the 2024 Reverse Stock Split, especially if the market price of our common stock does not increase as a result of the 2024 Reverse Stock
Split. In addition, the 2024 Reverse Stock Split may increase the number of stockholders who own odd lots (less than 100 shares) of our common stock,
creating the potential for such stockholders to experience an increase in the cost of selling their shares and greater difficulty effecting such sales.

6

 
 
 
 
 
 
 
 
 
 
 
 
Following the 2024 Reverse Stock Split, the resulting market price of our common stock may not attract new investors, including institutional investors,
and may not satisfy the investing requirements of those investors. Consequently, the trading liquidity of our common stock may not improve.

There can be no assurance that the 2024 Reverse Stock Split will result in a share price that will attract new investors, including institutional investors. In
addition, there can be no assurance that the market price of our common stock will satisfy the investing requirements of those investors. As a result, the
trading liquidity of our common stock may not necessarily improve.

The  market  price  of  our  common  stock  and  the  trading  volume  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.

During 2023, the market price of our common stock fluctuated from a low of $1.70 per share to a high of $34.60 per share, and our stock price continues to
fluctuate.  The  market  price  and  trading  volume  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 consummate a strategic transaction;

● the trading volume of our common stock;

● 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;

● adverse effects on our business condition and results of operations from general economic and market conditions and overall fluctuations in the

United States and international markets, including deteriorating market conditions due to investor concerns regarding inflation;

● adverse developments affecting the financial services industry, including events or concerns involving liquidity, defaults or non-performance by

financial institutions that could adversely affect our business, financial condition or results of operations;

● 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.

Further, the stock market in general, and the market for health care and life sciences companies in particular, has recently experienced extreme price and
volume fluctuations. The volatility of our common stock is further exacerbated due to its low trading volume. 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.

7

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Trading of our common stock is limited, and trading restrictions imposed on us by applicable regulations may further reduce trading in our common
stock, making it difficult for our stockholders to sell their shares; and future sales of common stock could reduce our stock price.

Trading of our common stock is currently conducted on the NASDAQ Capital Market. The liquidity of our common stock is limited, including in terms of
the number of shares that can be bought and sold at a given price and reduction in security analysts’ and the media’s coverage of us, if any. These factors
may  result  in  different  prices  for  our  common  stock  than  might  otherwise  be  obtained  in  a  more  liquid  market  and  could  also  result  in  a  larger  spread
between the bid and ask prices for our common stock. In addition, in the absence of a large market capitalization, our common stock is less liquid than the
stock of companies with broader public ownership, and, as a result, the trading prices of our common stock may be more volatile. In the absence of an
active public trading market, an investor may be unable to liquidate his or her investment in our common stock. Trading of a relatively small volume of our
common stock may have a greater impact on the trading price of our stock. We cannot predict the prices at which our common stock will trade in the future,
if at all.

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, 2023, we had outstanding warrants to acquire 1,095,517 shares of our common stock, and stock options to purchase 9,624 shares of
our common stock. A significant number of such warrants have exercise prices above our common stock’s recent trading prices, but the holders have the
right to effect 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.

We have never paid dividends on our capital stock, and we do not anticipate paying dividends in the foreseeable future.

We have never paid dividends on any of our capital stock and currently intend to retain any future earnings to fund the growth of our business. We may also
enter into credit agreements or other borrowing arrangements in the future that will restrict our ability to declare or pay cash dividends on our common
stock.  Any  determination  to  pay  dividends  in  the  future  will  be  at  the  discretion  of  our  Board  of  Directors  and  will  depend  on  our  financial  condition,
operating results, capital requirements, general business conditions and other factors that our Board of Directors may deem relevant. As a result, capital
appreciation, if any, of our common stock will be the sole source of gain, if any, for the foreseeable future.

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  conflicts  between  Russia  and  Ukraine  and  Israel  and  Hamas,  terrorism  or  other  geopolitical  events.  Sanctions
imposed by the United States and other countries in response to such conflicts 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.

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.

Item 1C. Cybersecurity

Risk Management and Strategy

Following the March 2024 Private Placement, our focus has been on the identification of a privately held company to complete a reverse merger or similar
strategic  transaction.  While  we  continue  to  maintain  minimal  distribution,  marketing,  and  sales  support,  we  have  scaled  down  operations  to  the  core
functions  of  a  U.S.  Nasdaq  listed  company  to  conserve  cash  and  focus  on  the  functions  needed  to  pursue  potential  strategic  alternatives.  We  have
implemented risk management processes to manage the risks associated with reliance on vendors, critical service providers, and other third-parties that may
lead to a service disruption or an adverse cybersecurity incident. This includes an assessment of vendors during the selection/onboarding process and a
review of SOC 1 reports on an annual basis.

In addition, we maintain policies over areas such as information security, access on/offboarding, and access and account management, to help govern the
processes  put  in  place  by  management  designed  to  protect  our  IT  assets,  data,  and  services  from  threats  and  vulnerabilities.  We  partner  with  industry
recognized IT providers leveraging third-party technology and expertise. These third-party service providers are a key part of our current cybersecurity risk
management and provide services including, maintenance of an IT assets inventory, periodic vulnerability scanning, identity access management controls
including  restricted  access  of  privileged  accounts,  network  integrity  safeguarded  by  employing  web-based  software,  including  endpoint  protection,
endpoint detection and response, and remote monitoring management on all devices, industry-standard encryption protocols and critical data backups. Our
outsourced information technology consultant conducts proactive patching and monitoring of all of our existing systems and has implemented systems and
procedures to mitigate cybersecurity risks that we believe are appropriate for a company of our size, stage of growth and financial condition. In addition,
we carry insurance with coverage for cyber events that we believe is suitable for a company of our size, stage of growth and financial condition.

Governance

Management is responsible for the day-to-day management of the risks we face, while our Board of Directors and Audit Committee has responsibility for
the  oversight  of  risk  management,  including  risks  from  cybersecurity  threats.  In  its  risk  oversight  role,  our  Board  of  Directors  has  the  responsibility  to
satisfy  itself  that  the  risk  management  processes  designed  and  implemented  by  management  are  appropriate  and  functioning  as  designed.  The  Board  of
Directors  has  delegated  to  the  Audit  Committee  of  the  Board  of  Directors  the  responsibility  for  the  oversight  of  information  technology,  including
cybersecurity  risks.  Member(s)  of  management  assigned  with  cybersecurity  oversight  responsibility  and/or  third-party  consultants  providing  cyber  risk
services  brief  the  Audit  Committee  on  cyber  vulnerabilities  identified  through  the  risk  management  process,  emerging  threat  landscape  and  new  cyber
risks, and provide updates on our processes to prevent, detect, and mitigate cybersecurity incidents.

We face risks from cybersecurity threats that could have a material adverse effect on its business, financial condition, results of operations, cash flows or
reputation. We acknowledge that the risk of cyber incident is prevalent in the current threat landscape and that a future cyber incident may occur in the
normal course of its business. We proactively seek to detect and investigate unauthorized attempts and attacks against our IT assets, data, and services, and
to prevent their occurrence and recurrence where practicable through changes or updates to internal processes and tools and changes or updates to service
delivery; however, potential vulnerabilities to known or unknown threats will remain.

As  of  the  date  of  this  Annual  Report,  we  are  not  aware  of  any  cybersecurity  threats,  and  have  not  experienced  any  cybersecurity  incidents,  that  have
materially affected us, including our business strategy, results of operations or financial condition.

For additional information concerning risks related to cybersecurity, see Item 1A. Risk Factors: 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.

Item 2. Properties

The  Company  leased  10,100  square  feet  of  office  and  laboratory  space  at  our  headquarters  in  Rockville,  Maryland.  The  original  lease  term  expires  in
February 2032. Effective April 1, 2024, the Company entered into a lease assignment agreement where the Company assigned the lease to a third party.
The  Company’s  security  deposit  will  remain  with  the  landlord  and  be  repaid  over  time  as  agreed  upon  with  the  assignee  of  the  lease.  The  Company
previously leased 12,770 square feet of space at its facility in Woburn, Massachusetts, under an operating lease that expired in January 2022, which the
Company had sublet to a third party from February 2021 to January 2022.

Rent expenses under the Company’s facility operating leases for the years ended December 31, 2023 and 2022 were $618,764 and $594,569, respectively,
which for 2023 includes the rent expenses of Curetis and Ares Genetics through the insolvency filing date.

Item 3. Legal Proceedings

From time to time, we may be a party to litigation or subject to claims incident to the ordinary course of business. Although the results of litigation and
claims cannot be predicted with certainty, we do not believe we are party to any claim or litigation; the outcome of which, if determined adversely to us,
would individually or in the aggregate be reasonably expected to have a material adverse effect on our business. Regardless of the outcome, litigation can
have an adverse impact on us due to defense and settlement costs, diversion of management resources and other factors.

On November 6, 2023, Curetis filed a petition for insolvency with the district court of Stuttgart, Germany, and Ares Genetics filed a petition for insolvency
with the commercial court in Vienna, Austria. The insolvency proceedings of Curetis and Ares Genetics were adjudicated under the insolvency laws of
Germany  and  Austria,  respectively.  The  insolvency  administrator  for  each  entity  assumed  control  over  the  assets  and  liabilities  of  Curetis  and  Ares
Genetics,  respectively,  which  eliminated  the  authority  and  power  of  the  Company  and  its  officers  to  act  on  behalf  of  the  subsidiaries.  As  part  of  the
insolvency proceedings, in April 2024, the insolvency administrator for Curetis sold all of Curetis’ assets to Camtech Pte Ltd., a Singaporean family office.
In April 2024, the insolvency administrator for Ares Genetics sold all of Ares Genetics’ assets to bioMerieux S.A.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with our audited
consolidated financial statements and the accompanying notes thereto included elsewhere in this Annual Report. This discussion contains forward-looking
statements,  based  on  current  expectations  and  related  to  future  events  and  our  future  financial  performance,  that  involve  risks  and  uncertainties.  Our
actual results may differ materially from those anticipated in these forward-looking statements as a result of many important factors, including those set
forth in the section titled “Risk Factors” included under Part I, Item 1A of this Annual Report.

Overview

OpGen,  Inc.  (“OpGen”  or  the  “Company”)  was  incorporated  in  Delaware  in  2001.  On  April  1,  2020,  OpGen  completed  its  business  combination
transaction with Curetis N.V., a public company with limited liability under the laws of the Netherlands. As part of the transaction, the Company acquired
all the shares of Curetis GmbH, a private limited liability company organized under the laws of the Federal Republic of Germany (“Curetis”), and certain
other assets and liabilities of Curetis GmbH including all its shares of Ares Genetics GmbH (“Ares Genetics”). From inception through November 2023,
the Company operated as a precision medicine company harnessing the power of molecular diagnostics and informatics to help combat infectious disease.
The Company, along with its subsidiaries, Curetis and Ares Genetics, developed and commercialized 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.

During the year ended December 31, 2023, the Company implemented certain cash management initiatives, including restructuring its U.S. operations by
reducing headcount from 24 to 5 and has since continued scaling down operations at OpGen’s U.S. headquarters to the core functions of a U.S. Nasdaq
listed company with only minimal distribution, marketing, and sales support, allowing the Company to conserve cash and focus on the functions needed to
pursue potential strategic alternatives. However, on November 6, 2023, Curetis filed a petition for insolvency with the district court of Stuttgart, Germany,
and Ares Genetics filed a petition for insolvency with the commercial court in Vienna, Austria. The insolvency proceedings of Curetis and Ares Genetics
were adjudicated under the insolvency laws of Germany and Austria, respectively.

The insolvency administrators assumed control over the assets and liabilities of Curetis and Ares Genetics, respectively, which eliminated the authority and
power of the Company and its officers to act on behalf of the subsidiaries. The loss of control required that the Company no longer include Curetis and
Ares  Genetics  in  its  consolidated  financial  statements.  Prior  to  the  insolvency  filings,  Curetis  and  Ares  Genetics  had  been  included  in  the  Company’s
consolidated financial statements. Upon deconsolidation of Curetis and Ares Genetics, the Company recognized gains on deconsolidation of subsidiaries at
the subsidiary levels of $46.6 million for Curetis and $7.7 million for Ares Genetics, which was offset by a loss on deconsolidation of subsidiary for the
Company  of  $67.3  million.  The  deconsolidation  charges  to  operations  represent  the  excess  of  the  carrying  value  over  the  fair  value  of  the  Company’s
interest in and intercompany payables to and receivables from Curetis and Ares Genetics as of the insolvency filing date.

Since  the  insolvency  filings  and  through  the  three  months  ended  March  31,  2024,  the  Company  continues  to  sell  the  Curetis  Unyvero  products  to  its
existing customers in the United States via drop shipments from Curetis directly to customer locations. The Unyvero tests are 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. As of December 31, 2023, OpGen had an installed base of approximately 28 Unyvero A50 Analyzers
across  the  United  States  in  different  types  of  hospitals  and  laboratories,  including  installations  for  clinical  studies.  The  sale  of  Ares  Genetics’  related
products and services was discontinued during the first quarter of 2024 due to the sale of the Ares Genetics assets to a strategic acquiror by its insolvency
administrator in Austria.

12

 
 
 
 
 
 
 
 
 
In March 2024, the Company entered into a securities purchase agreement (the “March 2024 Purchase Agreement”) with David E. Lazar, pursuant to which
the Company agreed to sell 3,000,000 shares of Series E Convertible Preferred Stock (“Series E Preferred Stock”) to Mr. Lazar at a price of $1.00 per share
for aggregate gross proceeds of $3.0 million. In connection with the transactions contemplated by the March 2024 Purchase Agreement, the members of the
Board  of  Directors,  prior  to  the  closing  of  such  transactions,  resigned  and  a  new  Board  of  Directors  was  appointed,  of  which  Mr.  Lazar  was  appointed
Chairman. The focus of OpGen going forward under new leadership and a new Board of Directors will be on the identification of a privately held company
to complete a reverse merger or similar strategic transaction.

On May 9, 2024, the Company held a special meeting of stockholders to vote on certain matters, including the removal of certain restrictions applicable to
the voting of Mr. Lazar’s shares of Series E Preferred Stock. Following approval of the proposals at such special meeting, subject to limited exceptions,
Mr. Lazar may vote his shares without restrictions.

Following receipt of approval from stockholders at a special meeting of stockholders held on November 30, 2022, the Company filed an amendment to its
Amended and Restated Certificate of Incorporation to effect a one-for-twenty reverse stock split of the issued and outstanding shares of common stock on
January 5, 2023. All share amounts and per share prices in this Annual Report have been adjusted to reflect the reverse stock split.

Following  receipt  of  approval  from  stockholders  at  a  special  meeting  of  stockholders  held  on  May  9,  2024,  the  Company  filed  an  amendment  to  its
Amended  and  Restated  Certificate  of  Incorporation  to  effect  a  one-for-ten  reverse  stock  split  of  the  issued  and  outstanding  shares  of  common  stock  on
May 20, 2024. All share amounts and per share prices in this Annual Report have been adjusted to reflect the reverse stock split.

The Company’s headquarters are located at 9717 Key West Avenue, Suite 100, in Rockville, Maryland, through the end of the second quarter of 2024. The
Company operates 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 2022 and 2023:

● On  June  24,  2022,  the  Company  entered  into  an  At-the-Market,  or  ATM,  Offering  Agreement  (the  “2022  ATM  Agreement”)  with  H.C.
Wainwright  &  Co.,  LLC  (“Wainwright”),  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  $10.65  million  of  shares  of  the  Company’s  common  stock  through  Wainwright.  As  of
December 31, 2022, the Company sold 8,574 shares under the 2022 ATM Agreement totaling $1.03 million in gross proceeds and $0.99 million in
net proceeds. The Company did not sell any shares under the 2022 ATM Agreement in 2023.

● On October 3, 2022, the Company closed a registered direct offering of shares of common stock and Series C Mirroring Preferred Stock pursuant
to a securities purchase agreement entered into with a certain institutional investor. In the offering, the Company agreed to issue and sell to the
investor (i) 26,800 shares of the Company’s common stock, par value $0.01 per share, (ii) 33,810 shares of the Company’s Series C Mirroring
Preferred Stock, par value $0.01 per share and stated value of $0.01 per share, and (iii) pre-funded warrants to purchase an aggregate of 21,500
shares of common stock. Each share of common stock was sold at a price of $70.00 per share, each share of preferred stock was sold at a price of
$0.01 per share, and each pre-funded warrant was sold at an offering price of $68.00 per share underlying such pre-funded warrants, for aggregate
gross proceeds of $3.34 million before deducting the placement agent’s fees and the offering expenses, and net proceeds of $3.04 million. Under
the  purchase  agreement,  the  Company  also  agreed  to  issue  and  sell  to  the  investor,  in  a  concurrent  private  placement,  warrants  to  purchase  an
aggregate of 48,300 shares of common stock. In connection with the offering, the Company also entered into a warrant amendment agreement
with the investor pursuant to which the Company agreed to amend certain existing warrants to purchase up to 74,150 shares of common stock that
were previously issued to the investor in 2018 and 2021, with exercise prices ranging from $410.00 to $13,000.00 per share as a condition to their
purchase of the securities in the offering, as follows: (i) lower the exercise price of the investor’s existing warrants to $75.40 per share, (ii) provide
that  the  existing  warrants,  as  amended,  will  not  be  exercisable  until  six  months  following  the  closing  date  of  the  offering,  and  (iii)  extend  the
original expiration date of the existing warrants by five and one-half years following the close of the offering. The increase in fair value resulting
from  the  warrant  modifications  is  accounted  for  as  an  equity  issuance  cost,  resulting  in  a  debit  and  credit  to  additional  paid  in  capital  for
approximately $1.8 million. As of December 31, 2022, all 21,500 pre-funded warrants were exercised and all 33,810 shares of the Company’s
Series C Mirroring Preferred Stock were automatically cancelled and ceased to be outstanding following receipt of stockholder approval for the
Company’s reverse stock split on November 30, 2022. In connection with the Company’s best-efforts public offering consummated in May 2023,
the Company amended the exercise price of the existing warrants to $7.785 per share.

● On January 11, 2023, the Company closed a best-efforts public offering pursuant to a securities purchase agreement with a certain institutional
investor for the purchase of (i) 32,121 shares of the Company’s common stock, par value $0.01 per share, (ii) pre-funded warrants to purchase up
to an aggregate of 226,500 shares of common stock (the “Pre-funded Warrants”), (iii) Series A-1 common warrants to purchase an aggregate of
258,621 shares of common stock (the “Series A-1 Warrants”), and (iv) Series A-2 common warrants to purchase an aggregate of 258,621 shares of
common stock (the “Series A-2 Warrants,” and together with the Series A-1 Warrants, the “Common Warrants”). Each share of common stock and
accompanying Common Warrants were sold at a price of $29.00 per share and accompanying Common Warrants, and each Pre-funded Warrant
and accompanying Common Warrants were sold at an offering price of $28.90 per share underlying such Pre-funded Warrants and accompanying
Common  Warrants,  for  aggregate  gross  proceeds  of  approximately  $7.5  million  before  deducting  the  placement  agent’s  fees  and  the  offering
expenses,  and  net  proceeds  of  approximately  $6.9  million.  The  Common  Warrants  have  an  exercise  price  of  $26.50  per  share.  The  Series  A-1
Warrants  were  immediately  exercisable  upon  issuance  and  will  expire  five  years  following  the  issuance  date.  The  Series  A-2  Warrants  were
immediately  exercisable  upon  issuance  and  will  expire  eighteen  months  following  the  issuance  date.  Subject  to  certain  ownership  limitations
described in the Pre-funded Warrants, the Pre-funded Warrants were immediately exercisable and could be exercised at a nominal consideration of
$0.10  per  share  of  common  stock  any  time  until  all  the  Pre-funded  Warrants  are  exercised  in  full.  All  Pre-funded  Warrants  were  exercised  by
February 15, 2023. In connection with the Company’s best-efforts public offering consummated in May 2023, the Company amended the exercise
price of the Common Warrants to $7.785 per share.

● On  May  4,  2023,  the  Company  closed  a  best-efforts  public  offering  pursuant  to  a  securities  purchase  agreement  with  a  certain  institutional
investor, pursuant to which the Company issued and sold to the Investor (i) 60,500 shares of the Company’s common stock, par value $0.01 per
share, (ii) pre-funded warrants to purchase up to an aggregate of 389,083 shares of common stock, and (iii) common warrants to purchase up to an
aggregate of 449,583 shares of common stock. Each share of common stock and accompanying common warrant was sold at a price of $7.785 per
share  and  accompanying  common  warrant,  and  each  pre-funded  warrant  and  accompanying  common  warrant  was  sold  at  an  offering  price  of
$7.685 per share underlying such pre-funded warrant and accompanying common warrant, for aggregate gross proceeds of  approximately  $3.5
million and net proceeds of approximately $3.0 million. The common warrants have an exercise price of $7.785 per share and will be exercisable
beginning on the date of stockholder approval of the exercisability of the warrants under Nasdaq rules or may be exercised through October 26,
2023, pursuant to the Warrant Inducement Agreement entered into on October 12, 2023. Pursuant to amendment agreements entered into by the
Company  and  Holder  on  October  26,  2023  and  February  7,  2024,  the  Company  agreed  to  initially  extend  the  offer  period  until  December  31,
2023, and subsequently extend the offer period until April 30, 2024. In order to permit the exercise of the Existing Warrants pursuant to the rules
of the Nasdaq Capital Market, the Holder agreed to pay as additional consideration $0.25 per share of common stock issued upon exercise of the
Existing Warrants. The common warrants not exercised as part of the Inducement Agreement will expire on the five-year anniversary of the date
of  such  stockholder  approval.  Each  pre-funded  warrant  has  an  exercise  price  per  share  of  common  stock  equal  to  $0.10  per  share  and  may  be
exercised at any time until the pre-funded warrants are exercised in full. In connection with the offering, the Company also entered into a warrant
amendment agreement with the investor pursuant to which the Company amended certain existing warrants to purchase up to 639,691 shares of
common stock that were previously issued in 2018, 2021, 2022 and 2023 to the investor, with exercise prices ranging from $26.50 to $75.40 per
share, in consideration for their purchase of the securities in the offering, as follows: (i) lower the exercise price of the existing warrants to $7.785
per share, (ii) provide that the existing warrants, as amended, will not be exercisable until the receipt of stockholder approval for the exercisability
of the common warrants in the offering, and (iii) extend the original expiration date of the existing warrants by five years following the receipt of
such stockholder approval. The increase in fair value resulting from the warrant modifications is accounted for as an equity issuance cost, resulting
in a debit and credit to additional paid in capital of approximately $0.3 million. As of December 31, 2023, the Holder exercised 200,000 shares of
Common  Stock  under  the  Existing  Warrants  pursuant  to  the  Inducement  Agreement  for  aggregate  gross  proceeds  to  the  Company  of  $2.057
million before deducting financial advisory fees and other expenses payable by the Company. Pursuant to the Amendment on February 7, 2024,
the Company and the Holder agreed to extend the offer period until April 30, 2024; however, no additional warrants were exercised during the
extended  warrant  inducement  offer  period.  Since  the  warrant  inducement  period  was  not  extended  beyond  April  30,  2024,  the  Company  is
required to hold a stockholders’ meeting to obtain approval for the exercisability of the existing common warrants within 70 days of the end of the
extension period.

● On June 26, 2023, the Company announced that its subsidiary Curetis and the European Investment Bank (“EIB”) agreed in principle to certain
terms relating to the repayment of the second tranche of Curetis’ loan from the EIB pursuant to that certain Finance Contract, dated December 12,
2016, as amended, by and between Curetis and the EIB (the “Finance Contract”). The second tranche had a principal balance of €3 million plus
accumulated and deferred interest. The second tranche was drawn down in June 2018 and matured on June 22, 2023. On July 4, 2023, the EIB and
Curetis entered into a Standstill Agreement (the “Standstill Agreement”) pursuant to which the EIB agreed that, with respect to each default or
event  of  default  relating  to  such  second  tranche,  the  EIB  would  not  take  any  action  or  exercise  any  right  under  the  Finance  Contract  until  the
earlier of a restructuring of the second tranche and November 30, 2023. As a condition to entering into the Standstill Agreement, Curetis paid the
EIB a partial payment of interest on the second tranche of €1 million on June 22, 2023. In addition, Curetis agreed to certain undertakings during
the standstill period, including the delivery of a rolling cash flow forecast and to cause a third-party restructuring expert to prepare and deliver a
restructuring opinion to the EIB. On November 20, 2023, Curetis received a termination notice from the EIB terminating the Standstill Agreement
effective as of November 20, 2023. The EIB’s termination notice stated that the termination of the Standstill Agreement was as a result of and in
connection with certain defaults of the Standstill Agreement arising from, among other related reasons, Curetis’ and Ares’ entry into insolvency
proceedings. On December 4, 2023, the Company received a notice from the EIB stating that Curetis is in default of the Finance Contract as a
result of, among other things, Curetis’ failure to repay when due certain outstanding indebtedness under the Finance Contract. In its notice, the
EIB stated that, as of November 16, 2023, the aggregate amount of principal, accrued interest and all other amounts owed by Curetis to the EIB
under the Finance Contract was approximately 9.66 million euro and that interest will continue to accrue in accordance with the Finance Contract
until all amounts owed are paid in full. Pursuant to that certain Guarantee and Indemnity Agreement, dated July 9, 2020 (the “Guaranty”), between
the EIB and the Company, the EIB demanded that the Company, as guarantor, immediately repay the EIB all amounts owed to the EIB under the
Finance Contract and reserved all of its other rights and remedies in connection with the Finance Contract. As of the year ended December 31,
2023, the Guaranty remained unpaid and outstanding, with the liability reflected on the Company’s financial statements, which was previously on
Curetis’ balance sheet. In connection with the Company’s entry into the March 2024 Purchase Agreement with David E. Lazar on March 25, 2024,
the Company entered into settlement agreements with each of the EIB and Curetis and Curetis’ trustee in insolvency, pursuant to which the parties
agreed to settle outstanding liabilities amongst the parties. Pursuant to the settlement agreements, following the final closing of the transactions
contemplated by the March 2024 Purchase Agreement, the Company will pay $2.0 million of the proceeds to settle all outstanding debt of the
Company to each of EIB and Curetis. The settlement agreement with EIB also terminated the Guaranty.

● On October 11, 2023, the Company entered into a Preferred Stock Purchase Agreement (the “Purchase Agreement”) with a single investor (the
“Investor”), pursuant to which the Company agreed to issue and sell to the Investor in a private placement (the “Private Placement”) 1,000 shares
of the Company’s Series D Preferred Stock, par value $0.01 per share (the “Preferred Stock”). Each share of preferred stock was agreed to sell at a
price of $1,000 per share for expected aggregate gross proceeds of $1.0 million before deducting offering expenses. The Private Placement was
conducted in connection with the negotiation of a potential strategic transaction involving the Company and the Investor. The Company intended
to use the proceeds of the Private Placement to fund the Company’s operations while it pursued a potential strategic transaction with the Investor.
Pursuant to the Purchase Agreement, the Company filed a certificate of designation (the “Certificate of Designation”) with the Secretary of State
of the State of Delaware designating the rights, preferences and limitations of the shares of preferred stock on October 11, 2023. The Certificate of
Designation provides that the shares of preferred stock have a stated value of $1,000 per share and are convertible into shares of common stock,
par  value  $0.01  per  share  of  the  Company  at  a  price  of  $4.09  per  share,  subject  to  adjustment  in  the  event  of  certain  stock  dividends  and
distributions,  stock  splits,  stock  combinations,  reclassifications,  or  similar  events  affecting  the  common  stock.  The  preferred  stock  may  be
converted at any time at the option of the holder. Notwithstanding the foregoing, the Certificate of Designation provides that in no event will the
preferred stock be convertible into common stock in a manner that would result in the holder, its permitted transferees and affiliates holding more
than 19.99% (together with any shares of common stock otherwise held by the Investor, its permitted transferees and their affiliates) of the then
issued and outstanding common stock (the “Ownership Limitation”), prior to the date that the Company’s stockholders approve the issuance of
shares of common stock to the holder upon conversion of the preferred stock (the “stockholder approval”). Upon receipt of stockholder approval,
the  shares  of  preferred  stock  will  automatically  be  converted  into  shares  of  common  stock  without  further  action  of  the  holder  thereof.  The
Investor funded $250,000 of the expected aggregate gross proceeds of $1.0 million before deducting offering expenses on November 14, 2023. On
December 13, 2023, in coordination with the Investor, the Company issued to the Investor 250 shares of Series D Preferred Stock in consideration
for  the  partial  payment.  As  of  December  31,  2023,  all  250  Series  D  Preferred  Shares  remain  outstanding  and  the  remaining  $750,000  of  the
purchase price remains unpaid. The Company reserves all rights and remedies arising from the Investor’s failure to close the transaction and the
Investor will continue to be in breach of the Purchase Agreement until the remaining amount is paid in full.

● On October 12, 2023, the Company entered into a warrant inducement agreement (the “Inducement Agreement”) with a holder (the “Holder”) of
certain existing warrants (the “Existing Warrants”) to purchase shares of common stock, par value $0.01 per share, of the Company. Pursuant to
the Inducement Agreement, the Holder agreed to exercise for cash their Existing Warrants to purchase up to 1,089,274 shares of the Company’s
common stock at an exercise price of $7.785 per share, the exercise price per share of the Existing Warrants, during the period from the date of the
Inducement Agreement until 7:30 a.m., Eastern Time, on October 26, 2023. Pursuant to amendment agreements entered into by the Company and
Holder  on  October  26,  2023  and  February  7,  2024,  the  Company  agreed  to  initially  extend  the  offer  period  until  December  31,  2023,  and
subsequently  extend  the  offer  period  until  April  30,  2024.  In  order  to  permit  the  exercise  of  the  Existing  Warrants  pursuant  to  the  rules  of  the
Nasdaq  Capital  Market,  the  Holder  agreed  to  pay  as  additional  consideration  $0.25  per  share  of  common  stock  issued  upon  exercise  of  the
Existing Warrants. In consideration of the Holder’s agreement to exercise the Existing Warrants in accordance with the Inducement Agreement,
the Company agreed to issue new warrants (the “Inducement Warrants”) to purchase shares of common stock equal to 100% of the number of
shares of common stock issued upon exercise of the Existing Warrants (the “Inducement Warrant Shares”). The Inducement Warrants will have an
exercise  price  of  $3.36  per  share  and  will  be  exercisable  on  the  six-month  anniversary  of  the  date  of  issuance  and  expire  on  the  five-year
anniversary of the Inducement Warrant’s first becoming exercisable. As of December 31, 2023, the Holder exercised 200,000 shares of Common
Stock under the Existing Warrants pursuant to the Inducement Agreement for aggregate gross proceeds to the Company of $2.057 million before
deducting financial advisory fees and other expenses payable by the Company. The Holder did not exercise any additional Existing Warrants after
December  31,  2023.  Since  the  warrant  inducement  period  was  not  extended  beyond  April  30,  2024,  the  Company  is  required  to  hold  a
stockholders’ meeting to obtain approval for the exercisability of the existing common warrants within 70 days of the end of the extension period.

16

 
 
 
 
In addition, subsequent to December 31, 2023, on March 25, 2024, the Company entered into the March 2024 Purchase Agreement with David E. Lazar,
pursuant to which the Company agreed to sell 3,000,000 shares of Series E Convertible Preferred Stock (“Series E Preferred Stock”) to Mr. Lazar at a price
of $1.00 per share for aggregate gross proceeds of $3.0 million. The proceeds of the transaction will be used to repay and settle outstanding indebtedness
and liabilities of the Company and for other general corporate and operating purposes. On March 25, 2024, Mr. Lazar paid $200,000 at the initial closing of
the  transactions  under  the  March  2024  Purchase  Agreement  in  exchange  for  200,000  shares  of  Series  E  Preferred  Stock.  Mr.  Lazar  subsequently  paid
$200,000  and  $150,000  on  April  5,  2024  and  April  23,  2024,  respectively,  in  exchange  for  an  additional  350,000  shares  of  Series  E  Preferred  Stock.
Mr. Lazar is expected to fund the remaining $2.45 million in early June 2024, at which time he will receive the remaining 2.45 million shares of Series E
Preferred Stock.

Financial Overview

Revenue

During the years ended December 31, 2023 and 2022, we recognized three types of revenues: product sales, laboratory services and collaboration revenue.
We generated product revenues from sales of our products, including through our distribution partners, such as our Unyvero instruments and consumables.
We also generated revenue from sales by OpGen’s subsidiary, Ares Genetics, of its AI-powered prediction models and solutions. Revenues generated from
our laboratory services relate to services that we and our subsidiaries provide to customers. Lastly, our collaboration revenues consist of revenue received
from research and development collaborations that we have entered into with third parties, such as our collaboration agreement with FIND.

Cost of Products, Cost of Services, and Operating Expenses

Our cost of products consists of product and inventory costs, including materials costs and overhead, and other costs related to the recognition of revenue.
Cost  of  services  relate  to  the  material  and  labor  costs  associated  with  providing  our  services.  Research  and  development  expenses  consist  primarily  of
expenses  incurred  in  connection  with  our  clinical  and  pre-clinical  research  activities.  Selling,  general  and  administrative  expenses  consist  of  public
company costs, salaries, and related costs for administrative, sales, and business development personnel.

The Company’s total revenue for the year ended December 31, 2023 increased 31%, from $2.6 million to $3.4 million, when compared to the same period
in 2022. This increase is primarily attributable to:

● Product Sales: the increase in revenue of approximately 27% in 2023 compared to 2022 is primarily attributable to the Company completing a

one-time sale of 25 sets of Unyvero instruments to a strategic partner in Q4 2023;

● Laboratory Services: the decrease in revenue of approximately 11% in 2023 compared to 2022 is primarily attributable to the insolvency filings of
Curetis and Ares Genetics in early November 2023, resulting in just over 10 months of revenue activity in 2023 compared to 12 months in 2022;
and

● Collaboration  Revenue:  the  increase  in  revenue  of  approximately  60%  in  2023  compared  to  2022  is  primarily  attributable  to  extensions  and

expansions of the Company’s collaboration with FIND in 2023.

The Company’s total operating expenses for the year ended December 31, 2023 decreased 8%, from $37.2 million to $34.2 million, when compared to the
same period in 2022. This decrease is primarily attributable to:

● Costs of products sold: expenses for the year ended December 31, 2023 decreased approximately 7% when compared to the same period in 2022.
The decrease in cost of products sold is primarily attributable to increases of only $1.3 million in inventory reserves for obsolescence, expirations,
and slow-moving inventory in 2023 compared to $1.7 million in 2022;

● Costs of services: expenses for the year ended December 31, 2023 increased approximately 307% when compared to the same period in 2022. The

increase in cost of services is primarily attributable to additional expenses from the Company’s collaboration with FIND in 2023;

● Research and development: expenses for the year ended December 31, 2023 decreased approximately 42% when compared to the same period in
2022. The decrease in research and development expenses is primarily attributable to the completion of clinical trials for Unyvero UTI in 2022,
slower than anticipated project developments in 2023, understaffing across the Company, and the shortened operating period for Curetis and Ares
Genetics due to the insolvency filings in November 2023;

● General and administrative: expenses for the year ended December 31, 2023 decreased approximately 9% when compared to the same period in

2022, primarily due to a reduction in payroll related costs resulting from the Company’s cash management activities;

● Sales and marketing: expenses for the year ended December 31, 2023 decreased approximately 36% when compared to the same period in 2022,
primarily due to the Company’s reduction in force at its Rockville, MD office and the shortened operating period for Curetis and Ares Genetics
due to the insolvency filings in November 2023;

● Loss on deconsolidation of subsidiaries: loss on deconsolidation of subsidiaries for the year ended December 31, 2023 represents the loss incurred

by the Company associated with the insolvency filings of Curetis and Ares Genetics in November 2023;

● Impairment  of  right-of-use  asset:  impairment  of  right-of-use  asset  for  the  year  ended  December  31,  2023  represents  the  impairment  of  the

Company’s right-of-use lease asset at its Rockville, MD office;

● Impairment of property and equipment: impairment of property and equipment for the year ended December 31, 2023 represents the impairment

of the Company’s property and equipment at its Rockville, MD office;

● Impairment  of  intangible  assets:  impairment  of  intangible  assets  for  the  year  ended  December  31,  2022  represents  the  impairment  of  the
Company’s infinite-lived intangible asset, which was deemed necessary since the contracted and expected future cash flows associated with these
assets did not support the carrying amount; and

● Goodwill impairment charge: goodwill impairment charge for the year ended December 31, 2022 represents the impairment of the Company’s

goodwill primarily due to decreases in the Company’s stock price and market capitalization.

Other expense for the year ended December 31, 2023 decreased to a net expense of $1.9 million from a net expense of $2.7 million in the same period in
2022. The decrease was primarily due to a reduction in interest expense as the Company repaid a portion of the outstanding debt.

Liquidity and Capital Resources

At December 31, 2023, the Company had cash and cash equivalents of $1.2 million, compared to $7.4 million at December 31, 2022. The Company has
funded its operations primarily through external investor financing arrangements and has raised significant funds in 2023 and 2022, including:

On June 24, 2022, we entered into the 2022 ATM Agreement with H.C. Wainwright, 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 $10.65 million of shares of the Company’s common stock through the
sales agent. As of December 31, 2022, the Company sold 8,574 shares under the 2022 ATM Offering totaling $1.03 million in gross proceeds and $0.99
million in net proceeds. The Company did not sell any shares under the 2022 ATM Agreement in 2023.

On  October  3,  2022,  we  closed  a  registered  direct  offering  for  the  purchase  of  26,800  shares  of  the  Company’s  common  stock,  33,810  shares  of  the
Company’s Series C Mirroring Preferred Stock, and pre-funded warrants to purchase an aggregate of 21,500 shares of common stock. The offering raised
aggregate gross proceeds of $3.34 million before deducting the placement agent’s fees and the offering expenses, and net proceeds of $3.04 million.

up to an aggregate of 226,500 shares of common stock, (iii) Series A-1 common warrants to purchase an aggregate of 258,621 shares of common stock,
and  (iv)  Series  A-2  common  warrants  to  purchase  an  aggregate  of  258,621  shares  of  common  stock.  The  offering  raised  aggregate  gross  proceeds  of
approximately $7.5 million before deducting the placement agent’s fees and the offering expenses, and net proceeds of approximately $6.9 million.

On May 4, 2023, we closed a best-efforts public offering for the purchase of (i) 60,500 shares of the Company’s common stock, par value $0.01 per share,
(ii) pre-funded warrants to purchase up to an aggregate of 389,083 shares of common stock, and (iii) common warrants to purchase up to an aggregate of
449,583  shares  of  common  stock.  The  offering  raised  aggregate  gross  proceeds  of  approximately  $3.5  million  and  net  proceeds  of  approximately  $3.0
million.

On October 6, 2023, Curetis received a payment of €0.75 million related to the sale of certain Unyvero A50 systems by Curetis to a strategic partner. Such
purchase of systems and payment was made in connection with the negotiation of a potential strategic transaction involving Curetis and the Company’s
subsidiary, Ares Genetics, with such strategic partner; however, the potential strategic transaction was unsuccessful.

On October 11, 2023, we entered into a Preferred Stock Purchase Agreement with a single investor for 1,000 shares of the Company’s Series D Preferred
Stock, par value $0.01 per share, where each share of preferred stock was agreed to sell at a price of $1,000 per share for aggregate gross proceeds of $1.0
million  before  deducting  offering  expenses.  The  investor  funded  $250,000  of  the  expected  aggregate  gross  proceeds  of  $1.0  million  before  deducting
offering  expenses  on  November  14,  2023.  On  December  13,  2023,  in  coordination  with  the  investor,  the  Company  issued  to  the  investor  250  shares  of
Series D Preferred Stock in consideration for the partial payment. As of December 31, 2023, all 250 Series D Preferred Shares remain outstanding and the
remaining $750,000 of the purchase price remains unpaid. The private placement was conducted in connection with the negotiation of a potential strategic
transaction involving the Company and the investor. The Company’s discussions with this investor have ceased.

On October 12, 2023, we entered into a warrant inducement agreement with a holder of certain existing warrants to purchase shares of common stock, par
value $0.01 per share, of the Company. Pursuant to the Inducement Agreement, the holder agreed to exercise for cash their existing warrants to purchase up
to 1,089,274 shares of the Company’s common stock at an exercise price of $7.785 per share, the exercise price per share of the existing warrants, during
the  period  from  the  date  of  the  Inducement  Agreement  until  7:30  a.m.,  Eastern  Time,  on  October  26,  2023;  however,  on  October  26,  2023,  and
subsequently on February 7, 2024, the Company and the holder agreed to initially extend the offer period through December 31, 2023, and later through
April 30, 2024. As of December 31, 2023, the holder exercised 200,000 shares of Common Stock under the existing warrants pursuant to the Inducement
Agreement for aggregate gross proceeds to the Company of $2.057 million before deducting financial advisory fees and other expenses payable by the
Company. The Holder did not exercise any additional Existing Warrants after December 31, 2023.

On November 6, 2023, Curetis filed a petition for insolvency with the district court of Stuttgart, Germany, and Ares Genetics filed a petition for insolvency
with the commercial court in Vienna, Austria, Reference Number 38 S 175/23x. The insolvency proceedings of Curetis and Ares Genetics were adjudicated
under the insolvency laws of Germany and Austria, respectively. The insolvency administrators assumed control over the assets and liabilities of Curetis
and Ares Genetics, respectively, which eliminated the authority and power of the Company and its officers to act on behalf of the subsidiaries. The German
and  Austrian  insolvency  administrators  both  successfully  completed  asset  sales  of  the  assets  of  Curetis  and  Ares  Genetics,  but  the  Company  does  not
anticipate receiving any proceeds from such sales as the proceeds will be allocated amongst each entity’s creditors.

To  meet  its  capital  needs,  the  Company  entered  into  a  securities  purchase  agreement  (the  “March  2024  Purchase  Agreement”)  with  David  E.  Lazar,
pursuant to which the Company agreed to sell 3,000,000 shares of Series E Convertible Preferred Stock (“Series E Preferred Stock”) to Mr. Lazar at a price
of $1.00 per share for aggregate gross proceeds of $3.0 million. Although Mr. Lazar is expected to provide the Company with $3.0 million in total funding,
the Company believes that current cash will only be sufficient to fund operations into the third quarter of 2024. 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 does not receive additional funding from
the individual investor or other investors or find a reverse merger partner or other strategic transaction partner before or during the third quarter of 2024, the
Company will not have sufficient cash flows and liquidity to finance its business operations. Accordingly, in such circumstances, the Company would be
compelled  to  immediately  reduce  general  and  administrative  expenses  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 seek to be acquired by another entity, cease operations and/or seek bankruptcy
protection. There can be no assurance that the Company will be able to identify or execute on any of these alternatives on acceptable terms or that any of
these alternatives will be successful.

On  March  10,  2023,  the  Company  learned  that  Silicon  Valley  Bank  (“SVB”)  was  closed  by  the  California  Department  of  Financial  Protection  and
Innovation, which appointed the Federal Deposit Insurance Corporation (“FDIC”) as receiver, due to the sudden and massive financial collapse of the bank.
On March 12, 2023, the Secretary of the Treasury, the chair of the Federal Reserve Board and the chairman of the FDIC released a joint statement related to
the FDIC’s resolution of the SVB receivership (the “Statement”). The Statement provided that “[d]epositors will have access to all of their money starting
Monday, March 13.” At the time, the Company had most of its cash and cash equivalents held in deposit accounts at SVB, which the Statement said the
Company  would  have  access  to  starting  on  March  13,  2023.  While  we  regained  access  to  our  accounts  at  Silicon  Valley  Bank  (now  a  division  of  First
Citizens Bank) and created additional banking relationships to diversify our holdings, future disruptions of financial institutions where we bank or have
credit arrangements, or disruptions of the financial services industry in general, could adversely affect our ability to access our cash and cash equivalents. If
we are unable to access our cash and cash equivalents as needed, our financial position and ability to operate our business will be adversely affected.

Net cash used in investing activities

Net cash used in investing activities in 2022 and 2023 consisted of purchases of property and equipment.

Net cash provided by (used in) financing activities

Net cash provided by financing activities in 2023 of $8.4 million consisted primarily of net proceeds from the January 2023 Offering of $6.9 million, the
May 2023 Offering of $3.0 million, and the October 2023 Warrant Inducement of $2.1 million, partially offset by payments on debt of $3.9 million. Net
cash used in financing activities in 2022 of $6.7 million consisted primarily of payments on debt of $10.8 million, partially offset by net proceeds from the
October 2022 Offering of $3.1 million and ATM offerings of $1.0 million.

Contractual Commitments

OpGen’s subsidiary, Curetis, has contractual commitments under its 2016 senior, unsecured loan financing facility of up to €25.0 million with the European
Investment  Bank  (“EIB”).  Following  the  consummation  of  our  business  combination  with  Curetis  in  April  2020,  the  Company  guaranteed  Curetis’
obligations under the loan financing facility. Curetis drew down three tranches under the facility: €10.0 million in April 2017, €3.0 million in June 2018,
and €5.0 million in June 2019. The first tranche had, and second tranche has, a floating interest rate of EURIBOR plus 4% payable after each 12-month-
period from the draw-down-date and an additional 6% interest per annum that is deferred and payable at maturity together with the principal. The third
tranche originally had a 2.1% PPI. Upon maturity of the third tranche, the EIB would have been 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 an amendment between the Company and the EIB on July 9, 2020, the parties
adjusted the PPI percentage applicable to the third EIB tranche of €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. This right constitutes an embedded derivative, which is separated
and measured at fair value with changes being accounted for through income or loss.

As  of  December  31,  2023,  the  outstanding  borrowings  under  all  tranches  were  €9.8  million  (approximately  $10.9  million),  including  deferred  interest
payable at maturity of €1.5 million (approximately $1.7 million).

On May 23, 2022, the Company and the EIB entered into a Waiver and Amendment Letter (the “2022 EIB Amendment”), which amended the EIB loan
facility.  The  2022  EIB  Amendment  restructured  the  first  tranche  of  approximately  €13.4  million  (including  accumulated  and  deferred  interest)  of  the
Company’s indebtedness with the EIB. Pursuant to the 2022 EIB Amendment, the Company repaid €5.0 million to the EIB in April 2022. The Company
also  agreed,  among  other  things,  to  amortize  the  remainder  of  the  debt  tranche  over  a  twelve-month  period  beginning  in  May  2022.  As  a  result,  the
Company paid twelve monthly installments totaling approximately €8.4 million through April 2023, at which point the first tranche was repaid in full. The
2022 EIB Amendment also provided for the increase of the PPI of the third tranche under the loan facility from 0.3% to 0.75% beginning in June 2024.

On July 4, 2023, the Company entered into a Standstill Agreement, by and among Curetis, as borrower, the Company and Ares Genetics, as guarantors, and
the EIB, as lender, relating to that certain Finance Contract, originally dated December 12, 2016, as amended, by and between Curetis and EIB. Pursuant to
the Standstill Agreement, the EIB agreed that, with respect to each default or event of default relating to €3 million in principal plus accumulated interest
that (i) was due and payable on June 22, 2023 under the Finance Contract and (ii) continues to exist as of the date of the Standstill Agreement, the EIB
would not take any action or exercise any right under the Finance Contract, including, but not limited to, any right of acceleration or termination, until the
earlier of the entry into a definitive agreement for the restructuring of the second tranche and November 30, 2023. As a condition of entering into such
standstill agreement, Curetis paid the EIB a partial payment of interest on the second tranche of €1 million on June 22, 2023. In addition, Curetis agreed to
certain undertakings during the standstill period, including the delivery of a rolling cash flow forecast and to cause a third-party restructuring expert to
prepare  and  deliver  a  restructuring  opinion  to  the  EIB.  On  November  20,  2023,  Curetis  received  a  termination  notice  from  the  EIB  terminating  the
Standstill Agreement effective as of November 20, 2023. The EIB’s termination notice stated that the termination of the Standstill Agreement was as a
result  of  and  in  connection  with  certain  defaults  of  the  Standstill  Agreement  arising  from,  among  other  related  reasons,  Curetis’  and  Ares’  entry  into
insolvency proceedings.

22

 
 
 
 
 
 
 
 
 
 
 
On December 4, 2023, the Company received a notice from the EIB stating that Curetis is in default of the Finance Contract as a result of, among other
things,  Curetis’  failure  to  repay  when  due  certain  outstanding  indebtedness  under  the  Finance  Contract.  In  its  notice,  the  EIB  stated  that,  as  of
November 16, 2023, the aggregate amount of principal, accrued interest and all other amounts owed by Curetis to the EIB under the Finance Contract was
approximately 9.66 million euro and that interest will continue to accrue in accordance with the Finance Contract until all amounts owed are paid in full.
Pursuant to that certain Guarantee and Indemnity Agreement, dated July 9, 2020 (the “Guaranty”), between the EIB and the Company, the EIB demanded
that the Company, as guarantor, immediately repay the EIB all amounts owed to the EIB under the Finance Contract and reserved all of its other rights and
remedies in connection with the Finance Contract. In connection with the Company’s entry into the March 2024 Purchase Agreement with David E. Lazar
on March 25, 2024, the Company entered into settlement agreements with each of the EIB and Curetis and Curetis’ trustee in insolvency, pursuant to which
the parties agreed to settle outstanding liabilities amongst the parties. Pursuant to the settlement agreements, following the final closing of the transactions
contemplated by the March 2024 Purchase Agreement, the Company will pay $2.0 million of the proceeds to settle all outstanding debt of the Company to
each of EIB and Curetis. The settlement agreement with the EIB also terminated the Guaranty.

Funding requirements

Going forward, our primary use of cash is to fund operating expenses, including those costs for general administrative and corporate purposes. Our future
funding requirements will depend on the costs required to comply with our obligations as a public company. 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  of  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.

Revenue Recognition

During  the  years  ended  December  31,  2022  and  2023,  the  Company  derived  revenues  from  (i)  the  sale  of  Unyvero  Application  cartridges,  Unyvero
Systems,  Acuitas  AMR  Gene  Panel  test  products,  and  SARS  CoV-2  tests,  (ii)  providing  laboratory  services,  and  (iii)  providing  collaboration  services
including funded software arrangements, license arrangements, and the FIND NGO collaboration on our Unyvero A30 platform.

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.

23

 
 
 
 
 
 
 
 
 
 
 
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.

Valuation of Inventory

The  Company’s  inventory  includes  Unyvero  system  instruments,  Unyvero  cartridges,  reagents  and  components  for  Unyvero,  and  supplies  used  for  the
Company’s  laboratory  services.  The  Company  periodically  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. Based on the Company’s assumptions and estimates, inventory reserves for obsolescence, expirations, and slow-moving inventory
were $1,280,805 at December 31, 2023.

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. During the year ended December 31, 2023, the Company determined that its operating right-of-use lease asset for its
Rockville, MD office was impaired due to the Company’s inability to support the lease given its financial position. As a result, the Company recorded an
impairment  charge  in  the  amount  of  $849,243.  In  addition,  for  the  year  ended  December  31,  2023,  the  Company  determined  that  its  property  and
equipment,  including  leasehold  improvements  and  computer  and  networking  equipment,  at  its  Rockville,  MD  office  was  impaired.  As  a  result,  the
Company recorded an impairment charge in the amount of $1,231,874.

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. All the Company’s finite-lived intangible assets with net balances were held
by Curetis and Ares Genetics. As a result of the insolvency filings for Curetis and Ares Genetics and the associated deconsolidation of all balance sheet
balances related to these entities, the Company does not have any finite-lived intangible asset balances as of December 31, 2023.

Acquired In-Process Research & Development (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. During the Company’s annual impairment test for its IPR&D intangible asset in 2022, it was determined that the infinite-lived intangible asset
was  impaired  because  although  the  Company  had  an  ongoing  collaboration  utilizing  the  intangible  asset,  the  contracted  cash  flow  associated  with  this
collaboration and projected future cash flows did not support the carrying amount. As a result, the Company recorded an impairment charge in the amount
of $5,407,699 for the year ended December 31, 2022.

24

 
 
 
 
 
 
 
 
 
 
 
Goodwill represented 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 conducts 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. As circumstances changed during the year ended December 31, 2022, that would, more likely than not, reduce the
Company’s fair value below its net equity value, the Company performed qualitative and quantitative analyses, assessing trends in market capitalization,
current and future cash flows, revenue growth rates, and the impact of global unrest and the COVID-19 pandemic on the Company and its performance.
Based on the analysis performed, and primarily due to changes in the Company’s stock price and market capitalization in the third quarter of 2022, it was
determined that goodwill was impaired. As a result, the Company recorded a goodwill impairment charge in the full amount of $6,940,549 for the year
ended December 31, 2022.

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 non-employees 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 of 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  of  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,  2023.  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, 2023.

Changes in Internal Control over Financial Reporting

For  the  year  ended  December  31,  2023,  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 then-appointed Company’s Chief Executive Officer and Chief Financial Officer, the Company assessed
the effectiveness of internal control over financial reporting as of December 31, 2023. 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, 2023, internal control over financial reporting is effective based on these
criteria.

Corporate Governance

Board and Board Committees

The Company’s Bylaws provide that the Board, by resolution adopted by a majority of the whole Board, may designate one or more other committees, with
each such committee to consist of two or more directors. As of the date of this Proxy Statement, the Board consists of four members.

The Board annually elects from its members the Audit and Compensation Committees. The Board may also from time to time appoint ad hoc committees.
Currently, the Board has not appointed a Nominating and Corporate Governance Committee. The Board believes the nominating and corporate governance
responsibilities are best handled at this time by the full Board given its size.

During its fiscal year ended December 31, 2023, the Board held 25 meetings. Each director attended at least 75% of the aggregate of all meetings of the
Board  and  the  Committees  on  which  each  such  director  served  held  during  2023.  The  Board  encourages  all  directors  to  attend  the  Company’s  annual
meeting of stockholders.

Each of the standing Committees of the Board operates pursuant to a written Committee Charter. Copies of these Charters can be obtained free of charge
from the Corporate Governance portion of the Investors section of the Company’s website, www.opgen.com.

Director Independence

An  “independent  director”  is  defined  generally  as  a  person  other  than  an  executive  officer  or  employee  of  the  company  or  its  subsidiaries  or  any  other
individual having a relationship which, in the opinion of the company’s Board of Directors, would interfere with the director’s exercise of independent
judgment in carrying out the responsibilities of a director. The Board has determined that, upon their appointments, Messrs. Ben-Tzvi, McMurdo and Natan
will  be  “independent”  directors  as  defined  in  the  applicable  Nasdaq  listing  standards  and  applicable  SEC  rules.  Our  independent  directors  will  conduct
regularly scheduled meetings at which only independent directors are present.

While Nasdaq listing standards generally require that a majority of the Board be independent, under NASDAQ Rule 4350(c), a controlled company (as
defined  by  Nasdaq  listing  standards)  is  exempt  from  certain  independent  director  requirements  set  forth  in  this  rule.  Following  the  Company’s  special
meeting of stockholders on May 9, 2024, the Company became a controlled company and may rely on such exemption.

Audit Committee

The current members of our audit committee are: David Natan (Chair), Matthew McMurdo, and Avraham Ben-Tzvi. Each member of the audit committee
is  expected  to  be  financially  literate,  and  Mr.  Natan  qualifies  as  an  “audit  committee  financial  expert”  as  defined  in  applicable  SEC  rules  and  has
accounting or related financial management expertise. During its fiscal year ended December 31, 2023, the former audit committee held 11 meetings. We
have adopted an audit committee charter that details the purposes and responsibilities of the committee, including:

-

-

-

-

appointing, approving the compensation of, and assessing the independence of our independent registered public accounting firm;

approving  auditing  and  permissible  non-audit  services,  and  the  terms  of  such  services,  to  be  provided  by  our  independent  registered  public
accounting firm;

reviewing  the  audit  plan  with  the  independent  registered  public  accounting  firm  and  members  of  management  responsible  for  preparing  our
financial statements;

reviewing and discussing with management and the independent registered public accounting firm our annual and quarterly financial statements
and related disclosures as well as critical accounting policies and practices used by us;

firm, whether our audited financial statements shall be included in our Annual Report on Form 10-K;

statements and accounting matters;

-

-

preparing the Audit Committee report required by SEC rules to be included in our annual proxy statement;

overseeing our compliance with applicable legal and regulatory requirements;

reviewing all related person transactions for potential conflict of interest situations and approving all such transactions; and

Compensation Committee

The current members of our compensation committee are: Matthew McMurdo (Chair), David Natan, and Avraham Ben-Tzvi. During its fiscal year ended
December 31, 2023, the former compensation committee held 4 meetings. We have adopted a compensation committee charter that details the purposes and
responsibilities of the committee, including:

-

-

-

-

-

-

-

-

annually  reviewing  and  recommending  to  our  Board  corporate  goals  and  objectives,  and  determining  the  achievement  thereof,  relevant  to  the
compensation of our Chief Executive Officer and other executive officers;

evaluating the performance of our Chief Executive Officer in light of such corporate goals and objectives and recommending to our Board the
compensation of our Chief Executive Officer;

determining, or reviewing and recommending to our Board for approval, the compensation of our other executive officers;

reviewing and establishing our overall management compensation philosophy and policy;

overseeing and administering our compensation and similar plans;

reviewing  and  discussing  with  management  the  compensation  discussion  and  analysis  to  be  included  in  our  annual  proxy  statement  or  Annual
Report on Form 10-K; and

reviewing and discussing with our Board corporate succession plans for the Chief Executive Officer and other key officers.

Nomination of Directors

The full Board acts to evaluate, on an annual basis, the composition of the Board and the skills, qualifications, business attributes and experience of the
existing Board members. The specific process for identifying and evaluating new directors, including stockholder-recommended nominees, if any, will vary
based  on  an  assessment  of  the  then-current  needs  of  the  Board  and  the  Company.  The  Board  will  determine  the  desired  profile  of  a  new  director,  the
competencies we are seeking, including experience in one or more areas of need, as determined by the Board. Candidates will be evaluated in light of the
target criteria chosen.

Procedures for Nominating a Director Candidate

The Board considers nominations by stockholders who recommend candidates for election to the Board. The Board evaluates nominees recommended by
stockholders in the same manner as it evaluates other nominees. A stockholder seeking to recommend a prospective candidate for the Board’s consideration
may do so by writing to the Corporate Secretary c/o OpGen, Inc., 9717 Key West Ave, Suite 100, Rockville, MD 20850.

With respect to the 2024 Annual Meeting of Stockholders, recommendations for director candidates must be received not later than the close of business on
the tenth day following the earlier of the day on which notice of the date of the meeting was mailed and public disclosure was made. Recommendations
submitted for consideration by the Board in preparation for the 2025 Annual Meeting of Stockholders must be received after the close of business on 120th
day prior to the first anniversary of the date on notice of the 2025 Annual Meeting of Stockholders is first made available to our stockholders, and no later
than  the  close  of  business  on  the  90th  day  prior  to  the  first  anniversary  of  the  date  on  which  such  notice  is  first  made  available  to  our  stockholders  in
connection with such meeting. However, if we change the date of the 2025 Annual Meeting by 30 days from the anniversary of the 2024 Annual Meeting
of Stockholders, recommendations for director candidates must be received not later than the close of business on the tenth day following the earlier of the
day on which notice of the date of the meeting was mailed and public disclosure was made.

Each notice of recommendation must contain the information required under our Bylaws, including: (a) for each person whom the stockholder proposes to
nominate  for  election  or  reelection  as  a  director,  all  information  relating  to  such  person  that  is  required  to  be  disclosed  in  solicitations  of  proxies  for
elections of directors, or is otherwise required, in each case pursuant to Regulation 14A under the Exchange Act (including such person’s written consent to
being  named  in  the  proxy  statement  as  a  nominee  and  to  serving  as  a  director  if  elected);  (b)  as  to  the  stockholder  giving  the  notice,  (i)  the  name  and
address, as they appear on the Company’s books, of such stockholder and (ii) the class and number of shares of the Company which are owned beneficially
and of record by such stockholder of record and by the beneficial owner, if any, on whose behalf the nomination is made; and (c) as to the beneficial owner,
if any, on whose behalf the nomination is made, (i) the name and address of such person and (ii) the class and number of shares of the Company which are
beneficially owned by such person. At the request of the Board, any person nominated by the Board for election as a director shall furnish to the Secretary
of the Company that information required to be set forth in a stockholder’s notice of nomination which pertains to the nominee.

Board Diversity

Although  the  Board  does  not  have  a  formal  diversity  policy,  in  addition  to  the  considerations  described  above,  the  Board  considers  race  and  gender
diversity in selection of qualified candidates as well as the overall skills and experience of such candidates. The following Board Diversity Matrix provides
certain information regarding the diversity of our current Board members based on such members’ self-identification.

The Board assesses this leadership structure to ensure the interests of the Company and its stockholders are best served. The Board does not currently have
a lead independent director. The Board determines what leadership structure it deems appropriate based on factors such as the experience of the applicable
individuals, the current business environment of the Company or other relevant factors. Currently, Mr. Lazar serves as the Company’s chairman.

The Board is responsible for oversight of the Company’s risk management practices, while management is responsible for the day-to-day risk management
processes. The Board receives periodic reports from management regarding the most significant risks facing the Company. We believe that this division of
responsibilities is the most effective approach for addressing the risks facing the Company, and the Company’s Board leadership structure will support this
approach.

Board Role in Risk Management

Our  Board  oversees  the  management  of  risks  inherent  in  the  operation  of  our  business  and  the  implementation  of  our  business  strategies.  Our  Board
performs  this  oversight  role  by  using  several  different  levels  of  review.  In  connection  with  its  reviews  of  the  operations  and  corporate  functions  of  our
Company, our Board addresses the principal risks associated with those operations and corporate functions. This includes risks relating to healthcare and
regulatory matters and compliance needs of the organization. In addition, our Board reviews the risks associated with our Company’s business strategies
periodically throughout the year as part of its consideration of undertaking any such business strategies.

Each  of  our  Board  committees  also  oversees  the  management  of  our  risk  that  falls  within  the  committee’s  areas  of  responsibility.  In  performing  this
function, each committee has full access to management, as well as the ability to engage advisors. In connection with its risk management role, our Audit
Committee meets privately with representatives from our independent registered public accounting firm. The Audit Committee oversees the operation of
our risk management program, including the identification of the principal risks associated with our business and periodic updates to such risks, and reports
to our Board regarding these activities.

The Compensation Committee assesses the impact risks inherent in the annual and long-term incentive plans could have on the Company. After review, the
Compensation Committee does not believe that the Company’s executive compensation practices or programs are likely to have a material adverse effect
on the Company.

Delinquent Section 16(a) Reports

Section 16(a) of the Securities Exchange Act of 1934, as amended, requires the Company’s officers and directors and persons who own more than 10% of
the Company’s outstanding common stock to file with the SEC initial reports of ownership and reports of changes in ownership of common stock and any
other equity securities of the Company. Directors, officers, and greater than 10% stockholders are required by SEC regulations to furnish the Company with
copies of all Section 16(a) forms they file. Based solely on a review of the Company’s records and written representations by the persons required to file
such reports, all filing requirements of Section 16(a) were satisfied with respect to the 2023 fiscal year.

Code of Ethics

We  have  adopted  a  written  code  of  business  conduct  and  ethics  that  applies  to  our  directors,  officers  and  employees,  including  our  principal  executive
officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. A current copy of the code is posted
on the Corporate Governance section of our website, which is located at www.opgen.com. If we make any substantive amendments to, or grant any waivers
from, the code of business conduct and ethics for any officer, we will disclose the nature of such amendment or waiver on our website or in a Current
Report on Form 8-K.

Insider Trading Policies

We have adopted an insider trading policy governing the purchase, sale, and other dispositions of our securities by directors, officers, and employees. A
copy of the insider trading policy is attached as an exhibit to this Annual Report.

Communications with the Board of Directors

Stockholders who want to communicate with members of the Board, including the independent directors, individually or as a group, should address their
communications  to  the  Board,  the  Board  members  or  the  Board  committee,  as  the  case  may  be,  and  send  them  to  c/o  Chair  of  the  Audit  Committee,
OpGen, Inc., 9717 Key West Ave, Suite 100, Rockville, MD 20850. The Chair of the Audit Committee will forward all such communications directly to
such Board members. Any such communications may be made on an anonymous and confidential basis.

There have been no changes to the procedures by which interested parties may communicate with the Board.

Item 11. Executive Compensation

We are currently a “smaller reporting company” as defined by Item 10 of the Regulation S-K promulgated under the Securities Exchange Act of 1934, as

(1) The “Stock Awards” column reflects the grant date fair value for all restricted stock units awarded under the Amended and Restated 2015 Incentive
Plan  (the  “Plan”)  during  2023  and  2022,  respectively.  The  “Option  Awards”  column  reflects  the  grant  date  fair  value  for  all  stock  option  awards
granted  under  the  2015  and  2022  Incentive  Plans  during  2023  and  2022,  respectively.  These  amounts  are  determined  in  accordance  with  FASB
Accounting  Standards  Codification  718  (ASC  718),  without  regard  to  any  estimate  of  forfeiture  for  service  vesting.  Assumptions  used  in  the

Agreements with Our Named Executive Officers

Prior  to  the  initial  closing  of  the  March  2024  Private  Placement  in  March  2024,  the  Company  was  party  to  an  Executive  Employment  Agreement  with
Oliver Schacht, Ph.D., the Company’s Chief Executive Officer. Mr. Schacht’s employment agreement provided that Mr. Schacht would receive an annual
base salary of $408,000 per year and will be eligible to receive an annual bonus of up to $285,600, or seventy percent (70%) of the base salary. The annual
bonus  opportunity  was  based  on  key  performance  metrics  established  by  the  Board  of  the  Company.  Mr.  Schacht  was  also  entitled  to  participate  in  the
Company’s  standard  equity  incentive  and  benefits  plans.  In  connection  with  certain  cash  management  initiatives,  the  Company  temporarily  reduced
Mr.  Schacht’s  compensation  under  his  employment  agreement  to  $244,800  in  September  2023,  which  was  subsequently  increased  to  $300,000  in
January 2024.

In connection with the transactions contemplated by the March 2024 Private Placement, Mr. Schacht resigned at the Initial Closing, and the Company and
Mr.  Schacht  entered  into  a  new  employment  agreement  that  superseded  his  existing  employment  agreement  and  pursuant  to  which  Mr.  Schacht  would
continue as an employee for a transition period.

Prior  to  January  2024,  the  Company’s  subsidiary,  Curetis  GmbH,  was  party  to  employment  agreements  with  each  of  Mr.  Bacher  and  Mr.  Weber.
Mr. Bacher’s employment agreement provided that Mr. Bacher would receive a base salary of $300,000 per year and would be eligible to receive an annual
bonus of up to forty-five percent (45%) of the base salary. The annual bonus opportunity was based on key performance metrics established by the Board
and the Compensation Committee. Mr. Bacher was also entitled to participate in the Company’s 2015 Equity Incentive Plan. In connection with certain
cash  management  initiatives,  the  Company  temporarily  reduced  Mr.  Bacher’s  compensation  under  his  employment  agreement  to  $180,000  in
September 2023.

Mr. Weber’s employment agreement provided that Mr. Weber would receive a base salary of $300,000 per year and would be eligible to receive an annual
bonus of up to forty-five percent (45%) of the base salary. The annual bonus opportunity was based on key performance metrics established by the Board
and the Compensation Committee. Mr. Weber was also entitled to participate in the Company’s 2015 Equity Incentive Plan. In connection with certain cash
management initiatives, the Company temporarily reduced Mr. Weber’s compensation under his employment agreement to $180,000 in September 2023.

Following  January  2024,  as  a  result  of  Curetis  GmbH’s,  the  Company’s  subsidiary,  insolvency  proceedings,  the  Company  entered  into  consulting
agreements with each of Mr. Bacher and Mr. Weber to ensure that they would continue to be compensated at the same rates as under their employment
agreements while they continue to serve as officers of the Company. Following the initial closing of the March 2024 Private Placement, Mr. Bacher and
Mr. Weber resigned as officers of the Company, and their consulting agreements terminated in April 2024.

In  April  2024,  in  connection  with  Mr.  Lazar’s  appointment  as  our  Chief  Executive  Officer,  the  Company  entered  into  an  employment  agreement  with
Mr. Lazar. Pursuant to the employment agreement, the Company engaged Mr. Lazar to act as its Chief Executive Officer (“CEO”) and, effective April 1,
2024, is paid a base salary of $406,000 per annum, which shall be deferred and accrued until the Company’s compensation committee determines that the
Company is sufficiently liquid to pay the accrued salary. Under the employment agreement, Mr. Lazar will also be eligible for annual bonuses of up to
100% of his then current base salary (payable in cash or restricted stock) and an annual grant of incentive equity awards in an amount equal to 100% of his
then  current  base  salary.  The  employment  agreement  has  a  three  (3)  year  term.  Mr.  Lazar  is  also  entitled  to  a  bonus  upon  a  change  of  control  of  the
Company payable in a lump-sum amount equal to three percent (3%) of the increased valuation of the Company resulting from the change of control. Such
bonus is payable in cash, restricted stock or a combination thereof.

Director Compensation

Prior to the initial closing of the March 2024 Private Placement, our Board of Directors adopted a non-employee director compensation plan providing for
certain cash and equity compensation to be provided to the Company’s non-employee directors for their service on the Board and its committees. Pursuant
to  such  plan,  each  non-employee  director  received  an  annual  cash  retainer  of  $25,000,  or,  with  respect  to  the  Chairman  of  the  Board,  $75,000,  plus
additional annual cash compensation for the Board and committee chairs ($15,000 for Audit Committee and $12,000 for Compensation Committee) and for
committee members ($7,000 for Audit Committee and $6,000 for Compensation Committee). In addition, new non-employee directors received an initial
equity grant and each non-employee director received an annual equity grant. Under such program, each non-employee director received an initial grant of
between 1,500 and 3,000 restricted stock units and an annual grant to non-employee directors of 1,500 restricted stock units. All such awards are made
under the Company’s 2015 Equity Incentive Plan. For a portion of 2023, consistent with the Company’s cash management efforts, the Company reduced its
director  compensation  plan  by  forty  percent  (40%).  Mr.  Schacht  did  not  receive  additional  compensation  for  his  service  on  the  Board.  See  “Summary
Compensation Table” for his 2023 compensation.

Following the initial closing of the March 2024 Private Placement, the Company entered into director agreements with each of Messrs. Ben-Tzvi, Lazar,
McMurdo and Natan. Pursuant to the director agreements, each director will be entitled to receive from the Company a cash fee of $12,500 per quarter
(pro-rated for any partial quarter) plus a one-time fee of $50,000 upon signing their director agreements. Such cash fees will accrue until such time as the
Company raises sufficient capital to pay the accrued but unpaid cash fees or the director elects to convert such unpaid fees into shares of common stock of
the Company. The cash director fee would convert at a rate of $4.00 per share for each $1.00 of accrued and unpaid fee that is converted. In addition to the
quarterly cash fee, under the director agreements, each director was granted 100,000 shares of restricted common stock.

Compensation for the non-employee directors for the year ended December 31, 2023 was:

Item 12. Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters

The number of shares of the Company’s Common Stock outstanding at the close of business on April 15, 2024 was 1,262,491 shares. In addition, as of
April 15, 2024, there were 250 shares of Series D Preferred Stock outstanding and 400,000 shares of Series E Preferred Stock outstanding. Each share of
Series D Preferred Stock is convertible into 244.40 shares of Common Stock, and each share of Series E Preferred Stock is convertible into 2.40 shares of
Common Stock, in each case, subject to applicable ownership limitations that restrict a holder’s ability to convert in excess of designated percentages. The
following table sets forth the beneficial ownership of the Company’s common stock, as of April 15, 2024, by each Company director and executive officer,
and  by  all  directors  and  executive  officers  as  a  group.  Beneficial  ownership  is  determined  in  accordance  with  Rule  13d-3  under  the  Exchange  Act.  In
computing the number of shares beneficially owned by a person or a group and the percentage ownership of that person or group, shares of our common
stock subject to options and warrants currently exercisable or exercisable within 60 days after April 15, 2024 are deemed outstanding, but are not deemed
outstanding for the purpose of computing the percentage ownership of any other person. To the knowledge of the directors and executive officers of the
Company, as of April 15, 2024, there are no persons and/or companies who or which beneficially own, directly or indirectly, shares representing more than
5% of the voting rights attached to all outstanding shares of the Company, other than as set forth below. Unless otherwise indicated, the address of each
beneficial owner listed below is c/o OpGen, Inc., 9717 Key West Ave, Suite 100, Rockville, MD 20850.

Change of Control

As  disclosed  above,  in  March  2024,  the  Company  entered  into  the  March  2024  Purchase  Agreement  with  Mr.  Lazar,  pursuant  to  which  the  Company
agreed to sell 3,000,000 shares of Series E Preferred Stock to Mr. Lazar at a price of $1.00 per share for aggregate gross proceeds of $3.0 million. On
March 25, 2024, Mr. Lazar paid $200,000 at the initial closing of the transactions under the March 2024 Purchase Agreement in exchange for 200,000
shares of Series E Preferred Stock. Mr. Lazar subsequently paid $200,000 and $150,000 on April 5, 2024 and April 23, 2024, respectively, in exchange for
an additional 350,000 shares of Series E Preferred Stock. Mr. Lazar is expected to fund the remaining $2.45 million in early June 2024, at which time he
will receive the remaining 2.45 million shares of Series E Preferred Stock for an aggregate of 3.0 million shares of Series E Preferred Stock. Each share of
Series E Preferred Stock is convertible in 2.4 shares of common stock. Accordingly, following the final closing, upon conversion of all his shares of Series
E  Preferred  Stock,  Mr.  Lazar  will  be  entitled  to  receive  7.2  million  shares  of  common  stock,  which  would  represent  approximately  85%  of  the  total
outstanding shares of common stock of the Company.

2008 Plan

Our  2008  Stock  Option  and  Restricted  Stock  Plan,  as  amended,  or  2008  Plan,  was  approved  by  our  Board  and  stockholders  in  April  2008;  subsequent
increases in the number of shares available for awards under the 2008 Plan were approved by our Board and stockholders in January 2009, February 2011,
March 2012, December 2012, April 2014 and October 2014. As of December 31, 2022, a total of 290 shares of our common stock are reserved for issuance
under the 2008 Plan.

The 2008 Plan provided for the grant of stock options and restricted stock awards. The Compensation Committee determined the time or times at which a
stock option will vest or become exercisable and the terms on which such option will remain exercisable. The Compensation Committee determined the
conditions and restrictions and purchase price, if any, for grants or sales or restricted stock to plan participants. The Compensation Committee may also at
any time accelerate the vesting or exercisability of an award.

Under  the  2008  Plan,  in  the  event  of  any  dissolution  or  liquidation  of  the  Company,  the  sale  of  all  or  substantially  all  of  the  Company’s  assets,  or  the
merger or consolidation of the Company where the Company is not the surviving entity or which results in the acquisition of all or substantially all of the
Company’s  then  outstanding  common  stock,  the  Compensation  Committee  may:  (a)  provide  for  the  assumption  or  substitution  of  some  or  all  of  the
outstanding  awards;  (b)  provide  for  a  cash-out  payment;  or  (c)  in  the  case  there  is  no  assumption,  substitution  or  cash-out,  provide  that  all  awards  not
exercised or awards providing for the future delivery of common stock will terminate upon the closing of the transaction.

Following our 2015 Equity Incentive Plan, or 2015 Plan, becoming effective, no further grants have been or will be made under our 2008 Plan.

2015 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 grants of restricted stock, restricted stock
units,  stock  appreciation  rights,  dividend  equivalents  and  stock  payments  to  employees,  non-employee  directors  and  consultants.  The  2015  Plan  was
amended  by  the  Compensation  Committee  in  February  2017  to  revise  the  provisions  with  respect  to  net  settlement  of  awards  in  response  to  change  in
regulations, and to establish standard periods for exercise of vested stock options following termination of service events.

Administration. The Compensation Committee administers the 2015 Plan, including the determination of the recipient of an award, the number of shares or
amount of cash subject to each award, whether an option is to be classified as an incentive stock option or non-qualified stock option, and the terms and
conditions  of  each  award,  including  the  exercise  and  purchase  prices  and  the  vesting  and  duration  of  the  award.  Our  Board  may  appoint  one  or  more
separate committees of our Board, each consisting of one or more members of our Board, to administer our 2015 Plan with respect to employees who are
not subject to Section 16 of the Exchange Act. Subject to applicable law, our Board may also authorize one or more officers to designate employees, other
than employees who are subject to Section 16 of the Exchange Act, to receive awards under our 2015 Plan and/or determine the number of such awards to
be received by such employees subject to limits specified by our Board.

Authorized shares. Under our 2015 Plan, the aggregate number of shares of our common stock authorized for issuance may not exceed (1) 271 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 the number of shares subject to vesting restrictions under the 2008 Plan on 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  are
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 (i) 4% of the outstanding shares of our common stock on the last day of the immediately preceding fiscal year, and (ii) another lesser
amount determined by our Board. As of December 31, 2023, 11,852 shares remain available for future awards under the 2015 Plan.

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. No more than 800 shares may be delivered upon the exercise of incentive stock options granted
under the 2015 Plan.

Types of Awards

Stock options. A stock option is the right to purchase a certain number of shares of stock, at a certain exercise price, in the future. Under our 2015 Plan,
incentive stock options and non-qualified options must be granted with an exercise price of at least 100% of the fair market value of our common stock on
the date of grant. Incentive stock options granted to any holder of more than 10% of our voting shares must have an exercise price of at least 110% of the
fair market value of our common stock on the date of grant. The stock option agreement specifies the date when all or any installment of the option is to
become exercisable. Payment of the exercise price may be made in cash or, if provided for in the stock option agreement evidencing the award, (1) by
surrendering,  or  attesting  to  the  ownership  of,  shares  which  have  already  been  owned  by  the  optionee,  (2)  by  delivery  of  an  irrevocable  direction  to  a
securities  broker  to  sell  shares  and  to  deliver  all  or  part  of  the  sale  proceeds  to  us  in  payment  of  the  aggregate  exercise  price,  (3)  by  a  “net  exercise”
arrangement, or (4) by any other form that is consistent with applicable laws, regulations and rules.

Restricted stock.  Restricted  stock  is  a  share  award  that  may  be  subject  to  vesting  conditioned  upon  continued  service,  the  achievement  of  performance
objectives  or  the  satisfaction  of  any  other  condition  as  specified  in  a  restricted  stock  agreement.  Participants  who  are  granted  restricted  stock  awards
generally have all of the rights of a stockholder with respect to such stock, other than the right to transfer such stock prior to vesting.

Restricted stock units. Restricted stock units give recipients the right to acquire a specified number of shares of stock at a future date upon the satisfaction
of certain conditions, including any vesting arrangement, established by our Compensation Committee and as set forth in a restricted stock unit agreement.
Unlike  restricted  stock,  the  stock  underlying  restricted  stock  units  will  not  be  issued  until  the  restricted  stock  units  have  vested  and  are  settled,  and
recipients of restricted stock units generally will have no voting or dividend rights prior to the time the vesting conditions are satisfied and the award is
settled.

Dividend equivalents. At our Compensation Committee’s discretion, performance-based restricted stock or restricted stock unit awards may provide for the
right to dividend equivalents. Subject to the terms of the 2015 Plan, our Compensation Committee will determine the terms and conditions of any stock unit
award, which will be set forth in a stock unit agreement to be entered into between us and each recipient.

Stock appreciation rights. Stock appreciation rights typically will provide for payments to the recipient based upon increases in the price of our common
stock  over  the  exercise  price  of  the  stock  appreciation  right.  The  exercise  price  of  a  stock  appreciation  right  will  be  determined  by  our  Compensation
Committee, which shall not be less than the fair market value of our common stock on the date of grant. Our Compensation Committee may elect to pay
stock appreciation rights in cash or in common stock or in a combination of cash and common stock.

Performance-based awards. Awards under our 2015 Plan may be made subject to the attainment of performance goals.

Other Plan Features

No Transfer. Unless the agreement evidencing an award expressly provides otherwise, no award granted under the 2015 Plan may be transferred in any
manner (prior to the vesting and lapse of any and all restrictions applicable to shares issued under such award), other than by will or the laws of descent and
distribution, provided, however, that an incentive stock option may be transferred or assigned only to the extent consistent with Section 422 of the Code.

Adjustments. In the event of a recapitalization, stock split or similar capital transaction, our Compensation Committee will make appropriate and equitable
adjustments  to  the  number  of  shares  reserved  for  issuance  under  the  2015  Plan,  the  limitations  regarding  the  total  number  of  shares  underlying  awards
given to an individual participant in any calendar year, the number of shares that can be issued as incentive stock options, the number of shares subject to
outstanding awards and the exercise price under each outstanding option or stock appreciation right.

42

 
 
 
 
 
 
 
 
 
 
 
 
Change in Control. If we are involved in a merger or other reorganization, outstanding awards will be subject to the agreement of merger or reorganization.
Such agreement will provide for (1) the continuation of the outstanding awards by us if we are the surviving corporation, (2) the assumption or substitution
of the outstanding awards by the surviving corporation or its parent or subsidiary, (3) immediate vesting, exercisability and settlement of the outstanding
awards followed by their cancellation, or (4) settlement of the intrinsic value of the outstanding awards (whether or not vested or exercisable) in cash, cash
equivalents, or equity (including cash or equity subject to deferred vesting and delivery consistent with the vesting restrictions applicable to such award or
the underlying shares) followed by cancellation of such awards.

Termination or Amendment. Our Board may amend or terminate the 2015 Plan at any time, subject to stockholder approval where required by applicable
law. Any amendment or termination may not materially impair the rights of holders of outstanding awards without their consent. No incentive stock option
may be granted after the tenth anniversary of the date the 2015 Plan was adopted by our Board.

Effective Date. The 2015 Plan was initially adopted by our Board and subsequently approved by our stockholders in April 2015. The 2015 Plan became
effective on May 4, 2015. Awards may be granted under the 2015 Plan until April 1, 2025.

Amended and Restated Stock Option Plan

In connection with the consummation of the Company’s business combination transaction with Curetis N.V., on April 1, 2020, the Company assumed and
adopted the 2016 Stock Option Plan, as amended, of Curetis N.V., the former parent company of Curetis GmbH. The Company assumed the 2016 Stock
Option Plan as the Amended and Restated Stock Option Plan of the Company (the “A&R Plan”). In connection with the foregoing, the Company assumed
all  awards  thereunder  that  were  outstanding  as  of  April  1,  2020  and  converted  such  awards  into  options  to  purchase  shares  of  common  stock  of  the
Company pursuant to the terms of the applicable award.

The A&R Plan provides for the grant of stock options, which are the right to purchase a certain number of shares of stock, at a certain exercise price, in the
future. The stock option agreement specifies the date when all or any installment of the option is to become exercisable. The Compensation Committee
administers  the  A&R  Plan,  including  taking  all  actions  required  or  advisable  for  the  administration  and  proper  implementation  of  the  A&R  Plan;
interpreting the A&R Plan unless specifically provided otherwise in the A&R Plan; and making all other decisions necessary or advisable to enable the
administration and proper implementation of the A&R Plan. Under the A&R Plan, the aggregate number of shares of our common stock authorized for
issuance shall not exceed 677. Following the assumption of the A&R Plan, no further grants have been or will be made under the A&R Plan.

Under the A&R Plan, in the event of a “change in control”, as defined in the A&R Plan, all the outstanding options will vest fully at the date of the change
in control. However, in the event of a change in control due to a sale, merger, sale of substantially all of the assets or consolidation of the Company, all the
outstanding options will be addressed in the applicable acquisition agreement. Such agreement may at the sole discretion of the Compensation Committee
and  without  the  approval  or  the  advice  of  the  optionees  being  required,  provide  the  following:  (1)  the  continuation  of  the  outstanding  options  by  the
Company  (if  the  Company  is  the  company  that  continues  to  exist);  (2)  the  take-over  of  the  A&R  Plan  and  the  outstanding  options  by  the  acquiring
company or the company that continues to exist, or its parent company; (3) the replacement of the outstanding options by new option rights with conditions
that are equivalent to the conditions of the outstanding options by the acquiring company or the company that continues to exist, or its parent company; or
(4) the cancellation of each outstanding option in return for payment to the optionee of an amount per option equal to the difference between the fair market
value of the common stock of the Company at the time of the closing under the purchase, merger, or consolidation agreement less the option price.

Except as expressly provided for under the A&R Plan, the awards granted under the A&R Plan may not be sold, assigned, transferred, pledged, mortgaged
or otherwise disposed of. The Compensation Committee and the Board may alter, amend or terminate the Plan or any part thereof at any time and from
time to time, provided, however, that no such alteration or amendment shall adversely affect the rights relating to any options granted or shares acquired
upon exercise of options prior to that time.

2020 Stock Options Plan

The 2020 Stock Options Plan was approved by stockholders at the 2020 Annual Meeting of Stockholders and were granted on the date thereof. The 2020
Stock Options were granted with an exercise price equal to the fair market value of the common stock on the date of grant, or $424.00. No shares remain
available for future awards under the 2020 Stock Options Plan. The following sets forth the principal terms of, and constitutes, the 2020 Stock Options
Plan.

Administration. The Compensation Committee will administer the 2020 Stock Options Plan, including, whether, for U.S. taxpayer employees, an option is
to be classified as an incentive stock option or non-qualified stock option.

Authorized shares. The aggregate number of shares of our common stock authorized for issuance under the 2020 Stock Options Plan is 6,500 shares of
common  stock.  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. No more than 2,500 shares may be delivered upon the exercise of incentive stock options
granted under the 2020 Stock Options Plan.

Stock options. A stock option is the right to purchase a certain number of shares of stock, at a certain exercise price, in the future. Under our 2020 Stock
Options Plan, incentive stock options and non-qualified options must be granted with an exercise price of at least 100% of the fair market value of our
common stock on the date of grant. Incentive stock options granted to any holder of more than 10% of our voting shares must have an exercise price of at
least 110% of the fair market value of our common stock on the date of grant. The stock option agreement specifies the date when all or any installment of
the option is to become exercisable. For non-employee directors, payment of the exercise price must be made in cash. For executive officers, payment of
the  exercise  price  may  be  made  in  cash  or,  if  provided  for  in  the  stock  option  agreement  evidencing  the  award,  (1)  by  surrendering,  or  attesting  to  the
ownership of, shares which have already been owned by the optionee, (2) by delivery of an irrevocable direction to a securities broker to sell shares and to
deliver all or part of the sale proceeds to us in payment of the aggregate exercise price, (3) by a “net exercise” arrangement, or (4) by any other form that is
consistent with applicable laws, regulations and rules.

No Transfer.  No  award  granted  under  the  2020  Stock  Options  Plan  may  be  transferred  in  any  manner,  other  than  by  will  or  the  laws  of  descent  and
distribution, provided, however, that an incentive stock option may be transferred or assigned only to the extent consistent with Section 422 of the Code.

Adjustments. In the event of a recapitalization, stock split or similar capital transaction, the Compensation Committee will make appropriate and equitable
adjustments to the number of shares reserved for issuance under the 2020 Stock Options Plan, the number of shares that can be issued as incentive stock
options, the number of shares subject to outstanding awards and the exercise price under each outstanding stock option.

Change in Control. If we are involved in a merger or other reorganization, outstanding awards will be subject to the agreement of merger or reorganization.
Such agreement will provide for (1) the continuation of the outstanding awards by us if we are the surviving corporation, (2) the assumption or substitution
of the outstanding awards by the surviving corporation or its parent or subsidiary, (3) immediate vesting, exercisability and settlement of the outstanding
awards followed by their cancellation, or (4) settlement of the intrinsic value of the outstanding awards (whether or not vested or exercisable) in cash, cash
equivalents, or equity (including cash or equity subject to deferred vesting and delivery consistent with the vesting restrictions applicable to such award or
the underlying shares) followed by cancellation of such awards.

Termination  or  Amendment.  The  2020  Stock  Options  Plan  can  be  terminated  by  the  Board  of  Directors  or  Compensation  Committee  at  any  time,  and,
subject to stockholder approval where required by applicable law, can be amended. Any amendment or termination may not materially impair the rights of
holders of outstanding awards without their consent.

44

 
 
 
 
 
 
 
 
 
 
 
Effective Date. The 2020 Stock Options Plan became effective upon approval by the stockholders at the 2020 Annual Meeting of Stockholders. The 2020
Stock Options Plan will terminate upon the expiration or termination of the last outstanding award.

Awards to Non-Employee Directors. The 2020 Stock Options granted to the members of the Board have a one-year vesting schedule, vesting quarterly in
equal installments on the first day of each three-month period as long as the director is providing services to the Company on each such vesting date. The
term of such stock options is ten (10) years after the date of grant; provided, however, that any unvested stock options will expire if the director ceases
providing services to the Company, and a departing director will have ninety (90) days to exercise vested stock options after the director ceases providing
services to the Company.

Awards  to  Executive  Officers.  The  2020  Stock  Options  granted  to  the  executive  officers  have  a  four-year  vesting  schedule,  vesting  25%  on  the  first
anniversary of the date of grant and the remaining options vesting 6.25% on the quarterly anniversary of the first vesting date for a period of three years, as
long as the executive officer continues providing services to the Company on each such vesting date. The term of such stock options is ten (10) years after
the date of grant; provided, however, that any unvested stock options will expire if the executive officer ceases providing services to the Company, and a
departing officer will have ninety (90) days to exercise vested stock options after the executive officer ceases providing services to the Company.

2022 Inducement Plan

In connection with the appointment of the Company's former CFO, Mr. Weber, OpGen granted him an inducement grant of stock options to purchase an
aggregate of 1,050 shares of OpGen’s common stock with a grant date of January 3, 2022. The equity award was granted pursuant to Nasdaq Listing Rule
5635(c)(4)  inducement  grant  exception  as  a  component  of  Mr.  Weber’s  employment  compensation  and  was  granted  as  an  inducement  material  to  his
acceptance of employment with OpGen. The options have an exercise price of $216.00. The option award vests over a four-year period with 25% vesting
on the first anniversary of the date of grant, January 3, 2023, and in equal quarterly installments on each quarterly anniversary thereafter. The award is
subject to Mr. Weber’s continued service with OpGen through the applicable vesting dates.

Item 13. Certain Relationships and Related Person Transactions, and Director Independence

Certain Relationships and Related Person Transactions

Other  than  compensation  for  our  directors  and  named  executive  officers  that  are  described  elsewhere  in  this  Annual  Report  and  for  the  transactions
described below, there were and are no transactions or series of similar transactions, during or after our last two fiscal years, to which we were a party or
will be a party, in which: (i) the amounts involved exceeded or will exceed the lesser of $120,000 or one percent of the average of the Company’s total
assets at year-end for the past two completed fiscal years; and (ii) any of our directors, executive officers or holders of more than 5% of our capital stock, or
any member of the immediate family of the foregoing persons, had or will have a direct or indirect material interest.

In March 2024, we entered into a securities purchase agreement with David E. Lazar, a private investor, pursuant to which he agreed to purchase 3,000,000
shares of Series E Convertible Preferred Stock (the “Series E Preferred Stock”) of the Company at a price of $1.00 per share for aggregate gross proceeds
of  $3,000,000  (the  “March  2024  Private  Placement”).  The  final  closing  and  aggregate  purchase  price  is  expected  to  be  paid  in  early  June  2024,  upon
consummation  of  certain  conditions.  Each  share  of  Series  E  Preferred  Stock  is  convertible  into  2.40  shares  of  common  stock  (as  adjusted  for  the  2024
Reverse Stock Split). Upon conversion of all of the shares of Series E Preferred Stock, the Series E Preferred Stock would represent approximately 85% of
the Company’s total outstanding shares of common stock as of May 15, 2024. Upon the initial closing of the transaction, Mr. Lazar was appointed as our
Chief  Executive  Officer  and  to  our  Board.  Mr.  Lazar’s  compensation  for  service  as  our  Chief  Executive  Officer  is  described  in  Item  11  of  this  Annual
Report on Form 10-K, which information is incorporated herein by reference.

Policies for Approval of Related Person Transactions

We have adopted a written policy that transactions with directors, officers, and holders of 5% or more of our voting securities and their affiliates, each, a
related person, must be approved by our Audit Committee.

Director Independence

Information concerning the independence of the members of our Board of Directors is described in Item 11 of this Annual Report on Form 10-K and is
incorporated herein by reference.

Item 14. Principal Accounting Fees and Services

Independent Registered Public Accounting Firm

Our  Audit  Committee  previously  appointed  UHY  LLP  as  the  Company’s  independent  registered  public  accounting  firm  for  the  fiscal  year  ended
December 31, 2023 and related interim periods after CohnReznick LLP, the Company’s independent registered public accounting firm for the fiscal year
ended December 31, 2022, notified the Company that CohnReznick would decline to stand for re-appointment after completion of the audit for the fiscal
year  ended  December  31,  2022.  CohnReznick  had  served  as  the  Company’s  independent  registered  public  accounting  firm  since  2014.  In  light  of  such
determination  by  CohnReznick,  the  Company  conducted  a  competitive  selection  process  where  the  Audit  Committee  invited  several  public  accounting
firms to participate. Following the completion of such process, the Audit Committee selected UHY in March 2023 to serve as the Company’s independent
registered public accounting firm for the fiscal year ending December 31, 2023 and related interim periods. As previously disclosed in April 2024, UHY
notified the Company that it would resign as the Company’s independent registered public accounting firm effective as of April 22, 2024.

In light of such resignation, on April 23, 2024, the Board appointed and engaged Beckles & Co., Inc. (“Beckles”) to serve as the Company’s independent
registered public accounting firm for the fiscal year ending December 31, 2023 and upcoming interim period.

During the period of UHY’s engagement, which commenced in March 2023, UHY did not provide any report on the financial statements of the Company.
During the fiscal years ended December 31, 2023 and 2022 and the subsequent interim period through April 22, 2024, there were no: (1) disagreements
with UHY on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedures, which disagreements, if not
resolved to their satisfaction, would have caused them to make reference in connection with their opinion to the subject matter of the disagreement, or (2)
reportable events under Item 304(a)(1)(v) of Regulation S-K. During the Company’s fiscal years ended December 31, 2022 and December 31, 2021 and the
subsequent  interim  period  through  January  18,  2023,  there  were  no:  (i)  disagreements  with  CohnReznick  on  any  matter  of  accounting  principles  or
practices, financial statement disclosure, or auditing scope or procedures, which disagreement, if not resolved to their satisfaction, would have caused them
to make reference to the subject matter of the disagreement in their reports on the Company’s consolidated financial statements, or (ii) reportable events
under Item 304(a)(1)(v) of Regulation S-K. CohnReznick’s audit report on the Company’s consolidated financial statements as of and for the fiscal years
ended December 31, 2022 and 2021 did not contain an adverse opinion or a disclaimer of opinion, and was not qualified or modified as to uncertainty, audit
scope or accounting principles, except that the reports contained an explanatory paragraph stating that there was substantial doubt about the Company’s
ability to continue as a going concern.

Audit Fees

The  following  table  presents  the  aggregate  fees  billed  to  the  Company  by  UHY  and  CohnReznick  for  its  audits  of  the  Company’s  consolidated  annual
financial statements and other services for the years ended December 31, 2023 and 2022, respectively.

Policy on Audit Committee Pre-Approval

Our  Audit  Committee  has  a  policy  in  place  that  requires  its  review  and  pre-approval  of  all  audit  and  permissible  non-audit  services  provided  by  our
independent  registered  public  accounting  firm.  The  services  requiring  pre-approval  by  the  audit  committee  may  include  audit  services,  audit-related
services, tax services and other services. All such audit and permissible non-audit services were pre-approved in accordance with this policy during the
fiscal year ended December 31, 2023. The Audit Committee considers whether the provision of each non-audit service is compatible with maintaining the
independence of our independent registered public accounting firm. The responsibility to pre-approve audit and non-audit services may be delegated by the
Audit Committee to one or more members of the Audit Committee; provided that any decisions made by such member or members must be presented to
the full Audit Committee at its next scheduled meeting.

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 sheet of OpGen, Inc. and Subsidiaries (the “Company”) as of December 31, 2023, and the related
consolidated  statements  of  operations  and  comprehensive  loss,  stockholders’  equity  and  cash  flows  for  the  year  then  ended  and  the  related  notes
(collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position
of  the  Company  as  of  December  31,  2023,  and  the  results  of  its  operations  and  its  cash  flows  for  the  year  then  ended  in  conformity  with  accounting
principles generally accepted in the United States of America.

Prior Period Financial Statements

The  financial  statements  of  the  Company  as  of  December  31,  2022,  were  audited  by  other  auditors  whose  report  dated  March  30,  2023  expressed  an
unmodified opinion on those statements.

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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor
were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit 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  audit  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  audit  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 audit provides 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.

Revenue Recognition on Collaboration Agreements

As described in Note 11 to the consolidated financial statements, the Company recognizes revenue arising from a collaboration and license agreement with
FIND,  which  totaled  $0.6  million  for  the  year  ended  December  31,  2023.  The  promised  goods  and  services  represent  multiple  distinct  performance
obligations and the entire transaction price was allocated to these performance obligations and recognized over-time. When management concludes that a
contract should be recognized over-time, management must then determine the period over which revenue should be recognized and the method by which
to measure revenue. Management generally recognizes revenue as deliverables are accepted, but at times, management uses a cost-based input method,
which measures the extent of progress towards completion based on the ratio of actual costs incurred to the total estimated costs expected upon satisfying
the performance obligation.

The principal considerations for our determination that performing procedures relating to revenue recognition for the collaboration and license agreement
with FIND recognized under an input method is a critical audit matter due to the significant judgment by management when determining the total estimated
costs  expected  upon  satisfying  the  performance  obligation,  which  in  turn  led  to  significant  auditor  judgment,  subjectivity  and  effort  in  performing
procedures to evaluate the total estimated costs expected upon satisfying the performance obligation.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated
financial statements. These procedures included understanding the design and implementation of internal controls relating to the revenue arising from the
collaboration  and  license  agreement  with  FIND,  including  controls  over  the  total  estimated  costs  expected  upon  satisfying  the  performance  obligations.
These  procedures  also  included,  among  others,  evaluating  and  testing  management’s  process  for  determining  the  total  estimated  costs  expected  upon
satisfying  the  performance  obligations,  which  included  testing  actual  costs  incurred  and  evaluating  the  reasonableness  of  estimated  costs  to  satisfy  the
performance obligations. Evaluating the reasonableness of estimated costs to satisfy the performance obligation involved assessing management’s ability to
reasonably estimate costs to satisfy the performance obligation by (i) evaluating the appropriateness of changes to management’s estimates of total costs to
satisfy the performance obligations; (ii) performing a comparison of management’s prior period cost estimates to actual costs incurred; and (iii) evaluating
whether the cost estimates used by management were reasonable considering consistency with industry and company-specific data.

OpGen, Inc.
Notes to Consolidated Financial Statements

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 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”). As of December 31, 2022, Crystal GmbH has been dissolved and merged into Curetis GmbH. As of November 6, 2023, Curetis filed
a  petition  for  insolvency  with  the  district  court  of  Stuttgart,  Germany,  and  Ares  Genetics  filed  a  petition  for  insolvency  with  the  commercial  court  in
Vienna, Austria, and insolvency administrators in the respective jurisdictions assumed control over the assets and liabilities of these entities. For the years
ended December 31, 2023 and 2022, the Company’s headquarters were in Rockville, Maryland and the Company’s principal operations were in Rockville,
Maryland. The Company operates in one business segment.

OpGen Overview

From inception through November 2023, OpGen operated as a precision medicine company harnessing the power of molecular diagnostics and informatics
to  help  combat  infectious  disease.  The  Company,  along  with  its  subsidiaries,  Curetis  and  Ares  Genetics,  developed  and  commercialized  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.

During the year ended December 31, 2023, the Company implemented certain cash management initiatives, including restructuring its U.S. operations by
reducing headcount from 24 to 5 and has since continued scaling down operations at OpGen’s U.S. headquarters to the core functions of a U.S. Nasdaq
listed company with only minimal distribution, marketing, and sales support, allowing the Company to conserve cash and focus on the functions needed to
pursue potential strategic alternatives. However, on November 6, 2023, Curetis filed a petition for insolvency with the district court of Stuttgart, Germany,
and Ares Genetics filed a petition for insolvency with the commercial court in Vienna, Austria. The insolvency proceedings of Curetis and Ares Genetics
were adjudicated under the insolvency laws of Germany and Austria, respectively.

The insolvency administrators assumed control over the assets and liabilities of Curetis and Ares Genetics, respectively, which eliminated the authority and
power of the Company and its officers to act on behalf of the subsidiaries. The loss of control required that the Company no longer include Curetis and
Ares  Genetics  in  its  consolidated  financial  statements.  Prior  to  the  insolvency  filings,  Curetis  and  Ares  Genetics  had  been  included  in  the  Company’s
consolidated financial statements. Upon deconsolidation of Curetis and Ares Genetics, the Company recognized gains on deconsolidation of subsidiaries at
the subsidiary levels of $46.6 million for Curetis and $7.7 million for Ares Genetics, which was offset by a loss on deconsolidation of subsidiary for the
Company  of  $67.3  million.  The  deconsolidation  charges  to  operations  represent  the  excess  of  the  carrying  value  over  the  fair  value  of  the  Company’s
interest in and intercompany payables to and receivables from Curetis and Ares Genetics as of the insolvency filing date.

In March 2024, the Company entered into a securities purchase agreement (the “March 2024 Purchase Agreement”) with David E. Lazar, pursuant to which
the Company agreed to sell 3,000,000 shares of Series E Convertible Preferred Stock (“Series E Preferred Stock”) to Mr. Lazar at a price of $1.00 per share
for aggregate gross proceeds of $3.0 million. In connection with the transactions contemplated by the March 2024 Purchase Agreement, the members of the
Board  of  Directors  prior  to  the  closing  of  such  transactions  resigned,  and  a  new  Board  of  Directors  was  appointed,  of  which  Mr.  Lazar  was  appointed
Chairman. The focus of OpGen going forward under new leadership and a new Board of Directors will be on the identification of a privately held company
to complete a reverse merger or similar strategic transaction (see Note 12).

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.  The  Company  has  funded  its  operations  primarily  through  external  investor  financing  arrangements  and
significant actions taken by the Company, including the following:

● On October 12, 2023, the Company entered into a warrant inducement agreement (the “Inducement Agreement”) with a holder (the “Holder”) of
certain existing warrants (the “Existing Warrants”) to purchase shares of common stock, par value $0.01 per share, of the Company. Pursuant to
the Inducement Agreement, the Holder agreed to exercise for cash their Existing Warrants to purchase up to 1,089,274 shares of the Company’s
common stock at an exercise price of $7.785 per share, the exercise price per share of the Existing Warrants, during the period from the date of the
Inducement Agreement until 7:30 a.m., Eastern Time, on October 26, 2023. Pursuant to amendment agreements entered into by the Company and
Holder  on  October  26,  2023  and  February  7,  2024,  the  Company  agreed  to  initially  extend  the  offer  period  until  December  31,  2023,  and
subsequently extend the offer period until April 30, 2024 (see Note 12). In order to permit the exercise of the Existing Warrants pursuant to the
rules of the Nasdaq Capital Market, the Holder agreed to pay as additional consideration $0.25 per share of common stock issued upon exercise of
the  Existing  Warrants.  In  consideration  of  the  Holder’s  agreement  to  exercise  the  Existing  Warrants  in  accordance  with  the  Inducement
Agreement, the Company agreed to issue new warrants (the “Inducement Warrants”) to purchase shares of common stock equal to 100% of the
number of shares of common stock issued upon exercise of the Existing Warrants (the “Inducement Warrant Shares”). The Inducement Warrants
will have an exercise price of $3.36 per share and will be exercisable on the six-month anniversary of the date of issuance and expire on the five-
year  anniversary  of  the  Inducement  Warrant’s  first  becoming  exercisable.  As  of  December  31,  2023,  the  Holder  exercised  200,000  shares  of
Common Stock under the existing warrants pursuant to the Inducement Agreement for aggregate gross proceeds to the Company of $2.057 million
before deducting financial advisory fees and other expenses payable by the Company.

● On October 11, 2023, the Company entered into a Preferred Stock Purchase Agreement (the “Purchase Agreement”) with a single investor (the
“Investor”), pursuant to which the Company agreed to issue and sell to the Investor in a private placement (the “Private Placement”) 1,000 shares
of the Company’s Series D Preferred Stock, par value $0.01 per share (the “Preferred Stock”). Each share of preferred stock was agreed to sell at a
price of $1,000 per share for expected aggregate gross proceeds of $1.0 million before deducting offering expenses. The Private Placement was
conducted in connection with the negotiation of a potential strategic transaction involving the Company and the Investor. The Company intended
to use the proceeds of the Private Placement to fund the Company’s operations while it pursued a potential strategic transaction with the Investor.
Pursuant to the Purchase Agreement, the Company filed a certificate of designation (the “Certificate of Designation”) with the Secretary of State
of the State of Delaware designating the rights, preferences and limitations of the shares of preferred stock on October 11, 2023. The Certificate of
Designation provides that the shares of preferred stock have a stated value of $1,000 per share and are convertible into shares of common stock,
par  value  $0.01  per  share  of  the  Company  at  a  price  of  $4.09  per  share,  subject  to  adjustment  in  the  event  of  certain  stock  dividends  and
distributions,  stock  splits,  stock  combinations,  reclassifications,  or  similar  events  affecting  the  common  stock.  The  preferred  stock  may  be
converted at any time at the option of the holder. Notwithstanding the foregoing, the Certificate of Designation provides that in no event will the
preferred stock be convertible into common stock in a manner that would result in the holder, its permitted transferees and affiliates holding more
than 19.99% (together with any shares of common stock otherwise held by the Investor, its permitted transferees and their affiliates) of the then
issued and outstanding common stock (the “Ownership Limitation”), prior to the date that the Company’s stockholders approve the issuance of
shares of common stock to the holder upon conversion of the preferred stock (the “stockholder approval”). Upon receipt of stockholder approval,
the  shares  of  preferred  stock  will  automatically  be  converted  into  shares  of  common  stock  without  further  action  of  the  holder  thereof.  The
Investor funded $250,000 of the expected aggregate gross proceeds of $1.0 million before deducting offering expenses on November 14, 2023. On
December 13, 2023, in coordination with the Investor, the Company issued to the Investor 250 shares of Series D Preferred Stock in consideration
for  the  partial  payment.  As  of  December  31,  2023,  all  250  Series  D  Preferred  Shares  remain  outstanding  and  the  remaining  $750,000  of  the
purchase price remains unpaid. The Company reserves all rights and remedies arising from the Investor’s failure to close the transaction and the
Investor will continue to be in breach of the Purchase Agreement until the remaining amount is paid in full.

● On June 26, 2023, the Company announced that its subsidiary Curetis and the European Investment Bank (“EIB”) agreed in principle to certain
terms relating to the repayment of the second tranche of Curetis’ loan from the EIB pursuant to that certain Finance Contract, dated December 12,
2016, as amended, by and between Curetis and the EIB (the “Finance Contract”). The second tranche had a principal balance of €3 million plus
accumulated and deferred interest. The second tranche was drawn down in June 2018 and matured on June 22, 2023. On July 4, 2023, the EIB and
Curetis entered into a Standstill Agreement (the “Standstill Agreement”) pursuant to which the EIB agreed that, with respect to each default or
event  of  default  relating  to  such  second  tranche,  the  EIB  would  not  take  any  action  or  exercise  any  right  under  the  Finance  Contract  until  the
earlier of a restructuring of the second tranche and November 30, 2023. As a condition to entering into the Standstill Agreement, Curetis paid the
EIB a partial payment of interest on the second tranche of €1 million on June 22, 2023. In addition, Curetis agreed to certain undertakings during
the standstill period, including the delivery of a rolling cash flow forecast and to cause a third-party restructuring expert to prepare and deliver a
restructuring opinion to the EIB. On November 20, 2023, Curetis received a termination notice from the EIB terminating the Standstill Agreement
effective as of November 20, 2023. The EIB’s termination notice stated that the termination of the Standstill Agreement was as a result of and in
connection with certain defaults of the Standstill Agreement arising from, among other related reasons, Curetis’ and Ares’ entry into insolvency
proceedings. On December 4, 2023, the Company received a notice from the EIB stating that Curetis is in default of the Finance Contract as a
result of, among other things, Curetis’ failure to repay when due certain outstanding indebtedness under the Finance Contract. In its notice, the
EIB stated that, as of November 16, 2023, the aggregate amount of principal, accrued interest and all other amounts owed by Curetis to the EIB
under the Finance Contract was approximately 9.66 million euro and that interest will continue to accrue in accordance with the Finance Contract
until all amounts owed are paid in full. Pursuant to that certain Guarantee and Indemnity Agreement, dated July 9, 2020 (the “Guaranty”), between
the EIB and the Company, the EIB demanded that the Company, as guarantor, immediately repay the EIB all amounts owed to the EIB under the
Finance Contract and reserved all of its other rights and remedies in connection with the Finance Contract. As of the year ended December 31,
2023, the Guaranty remained unpaid and outstanding, with the liability reflected on the Company’s financial statements, which was previously on
Curetis’ balance sheet. In connection with the Company’s entry into the March 2024 Purchase Agreement with David E. Lazar on March 25, 2024,
the Company entered into settlement agreements with each of the EIB and Curetis and Curetis’ trustee in insolvency, pursuant to which the parties
agreed to settle outstanding liabilities amongst the parties. Pursuant to the settlement agreements, following the final closing of the transactions
contemplated by the March 2024 Purchase Agreement, the Company will pay $2.0 million of the proceeds to settle all outstanding debt of the
Company to each of EIB and Curetis. The settlement agreement with EIB also terminated the Guaranty (see Note 12).

● On  May  4,  2023,  the  Company  closed  a  best-efforts  public  offering  pursuant  to  a  securities  purchase  agreement  with  a  certain  institutional
investor, pursuant to which the Company issued and sold to the Investor (i) 60,500 shares of the Company’s common stock, par value $0.01 per
share, (ii) pre-funded warrants to purchase up to an aggregate of 389,083 shares of common stock, and (iii) common warrants to purchase up to an
aggregate of 449,583 shares of common stock. Each share of common stock and accompanying common warrant was sold at a price of $7.785 per
share  and  accompanying  common  warrant,  and  each  pre-funded  warrant  and  accompanying  common  warrant  was  sold  at  an  offering  price  of
$7.685 per share underlying such pre-funded warrant and accompanying common warrant, for aggregate gross proceeds of approximately $3.5
million and net proceeds of approximately $3.0 million. The common warrants have an exercise price of $7.785 per share and will be exercisable
beginning on the date of stockholder approval of the exercisability of the warrants under Nasdaq rules or may be exercised through October 26,
2023, pursuant to the Warrant Inducement Agreement entered into on October 12, 2023. Pursuant to amendment agreements entered into by the
Company  and  Holder  on  October  26,  2023  and  February  7,  2024,  the  Company  agreed  to  initially  extend  the  offer  period  until  December  31,
2023,  and  subsequently  extend  the  offer  period  until  April  30,  2024  (see  Note  12).  In  order  to  permit  the  exercise  of  the  Existing  Warrants
pursuant to the rules of the Nasdaq Capital Market, the Holder agreed to pay as additional consideration $0.25 per share of common stock issued
upon exercise of the Existing Warrants. The common warrants not exercised as part of the Inducement Agreement will expire on the five-year
anniversary of the date of such stockholder approval. Each pre-funded warrant has an exercise price per share of common stock equal to $0.10 per
share  and  may  be  exercised  at  any  time  until  the  pre-funded  warrants  are  exercised  in  full.  In  connection  with  the  offering,  the  Company  also
entered into a warrant amendment agreement with the investor pursuant to which the Company amended certain existing warrants to purchase up
to 639,691 shares of common stock that were previously issued in 2018, 2021, 2022 and 2023 to the investor, with exercise prices ranging from
$26.50  to  $75.40  per  share,  in  consideration  for  their  purchase  of  the  securities  in  the  offering,  as  follows:  (i)  lower  the  exercise  price  of  the
existing warrants to $7.785 per share, (ii) provide that the existing warrants, as amended, will not be exercisable until the receipt of stockholder
approval for the exercisability of the common warrants in the offering, and (iii) extend the original expiration date of the existing warrants by five
years following the receipt of such stockholder approval. The increase in fair value resulting from the warrant modifications is accounted for as an
equity  issuance  cost,  resulting  in  a  debit  and  credit  to  additional  paid  in  capital  of  approximately  $0.3  million.  As  of  December  31,  2023,  the
Holder  exercised  200,000  shares  of  Common  Stock  under  the  existing  warrants  pursuant  to  the  Inducement  Agreement  for  aggregate  gross
proceeds to the Company of $2.057 million before deducting financial advisory fees and other expenses payable by the Company.

● On January 11, 2023, the Company closed a best-efforts public offering pursuant to a securities purchase agreement with a certain institutional
investor for the purchase of (i) 32,121 shares of the Company’s common stock, par value $0.01 per share, (ii) pre-funded warrants to purchase up
to an aggregate of 226,500 shares of common stock (the “Pre-funded Warrants”), (iii) Series A-1 common warrants to purchase an aggregate of
258,621 shares of common stock (the “Series A-1 Warrants”), and (iv) Series A-2 common warrants to purchase an aggregate of 258,621 shares of
common stock (the “Series A-2 Warrants,” and together with the Series A-1 Warrants, the “Common Warrants”). Each share of common stock and
accompanying Common Warrants were sold at a price of $29.00 per share and accompanying Common Warrants, and each Pre-funded Warrant
and accompanying Common Warrants were sold at an offering price of $28.90 per share underlying such Pre-funded Warrants and accompanying
Common  Warrants,  for  aggregate  gross  proceeds  of  approximately  $7.5  million  before  deducting  the  placement  agent’s  fees  and  the  offering
expenses, and net proceeds of approximately $6.9  million.  The  Common  Warrants  have  an  exercise  price  of  $26.50 per share. The  Series  A-1
Warrants  were  immediately  exercisable  upon  issuance,  and  will  expire  five  years  following  the  issuance  date. The  Series  A-2  Warrants  were
immediately  exercisable  upon  issuance,  and  will  expire  eighteen  months  following  the  issuance  date.  Subject  to  certain  ownership  limitations
described in the Pre-funded Warrants, the Pre-funded Warrants were immediately exercisable and could be exercised at a nominal consideration of
$0.10  per  share  of  common  stock  any  time  until  all  the  Pre-funded  Warrants  are  exercised  in  full.  All  Pre-funded  Warrants  were  exercised  by
February 15, 2023. In connection with the Company’s best-efforts public offering consummated in May 2023, the Company amended the exercise
price of the Common Warrants to $7.785 per share.

● On October 3, 2022, the Company closed a registered direct offering of shares of common stock and Series C Mirroring Preferred Stock pursuant
to a securities purchase agreement entered into with a certain institutional investor. In the offering, the Company agreed to issue and sell to the
investor (i) 26,800 shares of the Company’s common stock, par value $0.01 per share, (ii) 33,810 shares of the Company’s Series C Mirroring
Preferred Stock, par value $0.01 per share and stated value of $0.01 per share, and (iii) pre-funded warrants to purchase an aggregate of 21,500
shares of common stock. Each share of common stock was sold at a price of $70.00 per share, each share of preferred stock was sold at a price of
$0.01 per share, and each pre-funded warrant was sold at an offering price of $68.00 per share underlying such pre-funded warrants, for aggregate
gross proceeds of $3.34 million before deducting the placement agent’s fees and the offering expenses, and net proceeds of $3.04 million. Under
the  purchase  agreement,  the  Company  also  agreed  to  issue  and  sell  to  the  investor,  in  a  concurrent  private  placement,  warrants  to  purchase  an
aggregate of 48,300 shares of common stock. In connection with the offering, the Company also entered into a warrant amendment agreement
with the investor pursuant to which the Company agreed to amend certain existing warrants to purchase up to 74,150 shares of common stock that
were previously issued to the investor in 2018 and 2021, with exercise prices ranging from $410.00 to $13,000.00 per share as a condition to their
purchase of the securities in the offering, as follows: (i) lower the exercise price of the investor’s existing warrants to $75.40 per share, (ii) provide
that  the  existing  warrants,  as  amended,  will  not  be  exercisable  until  six  months  following  the  closing  date  of  the  offering,  and  (iii)  extend  the
original expiration date of the existing warrants by five and one-half years following the close of the offering. The increase in fair value resulting
from  the  warrant  modifications  is  accounted  for  as  an  equity  issuance  cost,  resulting  in  a  debit  and  credit  to  additional  paid  in  capital  for
approximately $1.8 million. As of December 31, 2022, all 21,500  pre-funded  warrants  were  exercised  and  all  33,810 shares of the Company’s
Series C Mirroring Preferred Stock were automatically cancelled and ceased to be outstanding following receipt of stockholder approval for the
Company’s reverse stock split on November 30, 2022. In connection with the Company’s best-efforts public offering consummated in May 2023,
the Company amended the exercise price of the existing warrants to $7.785 per share.

● On  June  24,  2022,  the  Company  entered  into  an  At-the-Market,  or  ATM,  Offering  Agreement  (the  “2022  ATM  Agreement”)  with  H.C.
Wainwright  &  Co.,  LLC  (“Wainwright”),  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  $10.65  million  of  shares  of  the  Company’s  common  stock  through  Wainwright.  As  of
December 31, 2022, the Company sold 8,574 shares under the 2022 ATM Agreement totaling $1.03 million in gross proceeds and $0.99 million in
net proceeds. The Company did not sell any shares under the 2022 ATM Agreement in 2023.

To meet its capital needs, the Company entered into a securities purchase agreement (the “March 2024 Purchase Agreement”) with David E. Lazar,
pursuant to which the Company agreed to sell 3,000,000 shares of Series E Convertible Preferred Stock (“Series E Preferred Stock”) to Mr. Lazar at a price
of $1.00 per share for aggregate gross proceeds of $3.0 million. Although Mr. Lazar is expected to provide the Company with $3.0 million in total funding,
the Company believes that current cash will only be sufficient to fund operations into the third quarter of 2024. 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 does not receive additional funding from
the individual investor or other investors or find a reverse merger partner or other strategic transaction partner before or during the third quarter of 2024, the
Company will not have sufficient cash flows and liquidity to finance its business operations. Accordingly, in such circumstances, the Company would be
compelled  to  immediately  reduce  general  and  administrative  expenses  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 seek to be acquired by another entity, cease operations and/or seek bankruptcy
protection. There can be no assurance that the Company will be able to identify or execute on any of these alternatives on acceptable terms or that any of
these alternatives will be successful.

The accompanying consolidated financial statements do not include any adjustments related to the recoverability and classification of assets or the amounts
and classification of liabilities that may result from the possible inability of the Company to continue as a going concern.

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

Curetis and Ares Genetics are located in Holzgerlingen, Germany and Vienna, Austria, respectively, each of which use currencies other than the U.S. dollar
as their functional currency. As a result, all assets and liabilities of these entities 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, 2023 and 2022.

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, 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 5.

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. On March 10, 2023, the Company learned that Silicon Valley Bank (“SVB”), the Company’s primary bank at the time (now a division of
First  Citizens  Bank),  was  closed  by  the  California  Department  of  Financial  Protection  and  Innovation,  which  appointed  the  Federal  Deposit  Insurance
Corporation as receiver. The Company did not experience any losses in such accounts, but since the Company was exposed to credit risk with the failure of
SVB, management diversified the Company’s holdings to minimize credit risk in the future.

At December 31, 2023 and 2022, the Company had funds totaling $302,262 and $495,629, 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:

The  Company’s  accounts  receivable  result  from  revenues  earned  but  not  yet  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 90 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 as of December 31, 2023 and 2022.

At December 31, 2023, the Company had accounts receivable from three customers which individually represented 39%, 26%, and 10% of total accounts
receivable, respectively. At December 31, 2022, the Company had accounts receivable from two customers which individually represented 41% and 21%
of total accounts receivable, respectively. For the year ended December 31, 2023, revenue earned from three customers represented 24%, 19%, and 13% of
total  revenues,  respectively.  For  the  year  ended  December  31,  2022,  revenue  earned  from  three  customers  represented  32%,  14%,  and  11%  of  total
revenues, respectively.

Inventory includes Unyvero system instruments, Unyvero cartridges, reagents and components for Unyvero and Acuitas kits, and reagents and supplies
used for the Company’s laboratory services.

The Company periodically 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. Based on
the Company’s assumptions and estimates, inventory reserves for obsolescence, expirations, and slow-moving inventory were $1,280,805 and $1,694,843
at December 31, 2023 and December 31, 2022, respectively. Due to the insolvency proceedings and deconsolidation of the Company’s subsidiaries, the
Company reserved for the full value of its inventory at December 31, 2023 given the uncertainty surrounding the net realizable value and future demand for
the Company’s products.

The Company classifies finished goods 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 for property and equipment was $584,230 and $830,757 for the years ended December 31, 2023
and 2022, respectively. Property and equipment consisted of the following at December 31, 2023 and 2022:

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

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  year  ended  December  31,  2023,  the  Company  determined  that  its  property  and  equipment,  including
leasehold improvements and computer and networking equipment, at its Rockville, MD office was impaired due to the Company’s financial condition and
the impairment of the Company’s ROU lease asset. As a result, the Company recorded an impairment charge in the amount of $1,231,874. During the year
ended December 31, 2022, 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. Given the deconsolidation of Curetis and Ares Genetics following their insolvency filings, the ROU assets
associated with these entities are removed from the consolidated balance sheet for the year ended December 31, 2023. During the year ended December 31,
2023,  the  Company  determined  that  its  operating  right-of-use  lease  asset  for  its  Rockville,  MD  office  was  impaired  due  to  the  Company’s  inability  to
support the lease given its financial position. As a result, the Company recorded an impairment charge in the amount of $849,243. The Company did not
identify any impaired ROU assets for the year ended December 31, 2022.

Intangible assets and goodwill

Intangible assets and goodwill consist of finite-lived and indefinite-lived intangible assets and goodwill.

Finite-lived and indefinite-lived intangible assets

Intangible assets include trademarks and tradenames, developed technology and software, in-process research & development (“IPR&D”), and distributor
relationships and consisted of the following as of December 31, 2023 and 2022:

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. During the Company’s annual
impairment  test  for  its  IPR&D  intangible  asset  in  2022,  it  was  determined  that  the  infinite-lived  intangible  asset  was  impaired  because  although  the
Company had an ongoing collaboration utilizing the intangible asset, the contracted cash flow associated with this collaboration and projected future cash
flows  did  not  support  the  carrying  amount.  As  a  result,  the  Company  recorded  an  impairment  charge  in  the  amount  of  $5,407,699  for  the  year  ended
December 31, 2022.

Intangible  assets,  other  than  IPR&D  as  discussed  above,  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. All the Company’s finite-lived intangible assets with net balances were held by Curetis and Ares Genetics. As a result of the
insolvency filings for Curetis and Ares Genetics and the associated deconsolidation of all balance sheet balances related to these entities, the Company does
not have any finite-lived intangible asset balances as of December 31, 2023.

Total amortization expense of intangible assets was $624,240 and $725,060  for  the  years  ended  December  31,  2023  and  2022,  respectively.  Due  to  the
removal  of  the  Curetis  and  Ares  Genetics’  intangible  assets,  the  Company  does  not  anticipate  any  future  amortization  associated  with  these  intangible
assets.

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, 2022 was $0.

The changes in the carrying amount of goodwill as of December 31, 2022, and since December 31, 2021, were as follows:

Balance as of December 31, 2021
Changes in currency translation

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 year ended December 31, 2022, since the Company identified
circumstances  that  would,  more  likely  than  not,  reduce  the  Company’s  fair  value  below  its  net  equity  value,  the  Company  performed  qualitative  and
quantitative analyses, assessing trends in market capitalization, current and future cash flows, revenue growth rates, and the impact of global unrest and the
COVID-19 pandemic on the Company and its performance. Based on the analysis performed, and primarily due to changes in the Company’s stock price
and  market  capitalization  in  the  third  quarter  of  2022,  it  was  determined  that  goodwill  was  impaired.  As  a  result,  the  Company  recorded  a  goodwill
impairment charge in the full amount of $6,940,549 for the year ended December 31, 2022.

Revenue recognition

During  the  years  ended  December  31,  2022  and  2023,  the  Company  derived  revenues  from  (i)  the  sale  of  Unyvero  Application  cartridges,  Unyvero
Systems,  Acuitas  AMR  Gene  Panel  test  products,  and  SARS  CoV-2  tests,  (ii)  providing  laboratory  services,  and  (iii)  providing  collaboration  services
including funded software arrangements, license arrangements, and the FIND NGO collaboration on our Unyvero A30 platform.

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  recognized  funding  from  grants  and  research  incentives  received  through  its  subsidiary,  Ares  Genetics,  from
Austrian  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, 2023, the Company recognized $301,575 as a reduction of research and development expense related to Ares Genetics’
government grant arrangements. For the year ended December 31, 2022, the Company recognized $424,304 as a reduction of research and development
expense related to government grant arrangements. As of December 31, 2023 and 2022, the Company had earned but not yet received $0 and $401,436,
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.

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

The risk-free interest rate 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

The  expected  term  of  a  stock  option  grant  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 5.75 years for options with a standard two-year vesting period
and 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  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  $241,110,447  and  $232,682,072  at  December  31,  2023  and  2022,  respectively.
Despite the NOL carryforwards, which started expiring 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.

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.

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,  (iii)  restricted  stock  units
representing the right to acquire shares of common stock, and (iv) convertible preferred stock which have been excluded from the computation of diluted
loss per share, was 1.2 million shares and 0.1 million shares as of December 31, 2023 and 2022, respectively.

Adopted accounting pronouncements

In  June  2016,  the  Financial  Accounting  Standards  Board,  or  FASB,  issued  Accounting  Standards  Codification  (ASC)  Update  No.  2016-13,  Financial
Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The purpose of Update No. 2016-13 is to replace the
incurred loss impairment methodology for financial assets measured at amortized cost with a methodology that reflects expected credit losses and requires
consideration of a broader range of reasonable and supportable information, including forecasted information, to develop credit loss estimates. Update No.
2016-13 did not have a material impact on the Company’s financial position or results of operations.

In  May  2021,  the  FASB  issued  ASU  No.  2021-04,  Earnings  Per  Share  (Topic  260),  Debt  —  Modifications  and  Extinguishments  (Subtopic  470-50),
Compensation — Stock Compensation (Topic 718), and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40) (“ASU 2021-04”).
ASU 2021-04 clarifies and reduces diversity in an issuer’s accounting for modifications or exchanges of freestanding equity-classified written call options,
including warrants, that remain equity-classified after modification or exchange. ASU 2021-04 requires an entity to treat a modification or an exchange of a
freestanding equity-classified written call option that remains equity-classified after the modification or exchange as an exchange of the original instrument
for a new instrument and provides guidance on measuring and recognizing the effect of a modification or an exchange. The Company adopted ASU 2021-
04 on January 1, 2022. The adoption did not have a material impact on the Company’s consolidated financial statements and related disclosures.

Contract assets

The  Company  had  no  contract  assets  as  of  December  31,  2023  and  2022,  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, 2023 and 2022.

Note 5 - 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.

During the year ended December 31, 2023, 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 2016, Curetis entered into a contract for an up to €25.0 million senior, unsecured loan financing facility from the EIB (see Note 6). In June 2019, Curetis
drew down a third tranche of €5.0 million from the EIB. In return for the EIB waiving the condition precedent of a minimum cumulative equity capital
raised of €15.0 million to disburse this €5.0 million tranche, the parties agreed on a 2.1% participation percentage interest (“PPI”). Upon maturity of the
tranche, the 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  €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. On May 23, 2022, the Company entered into a Waiver and Amendment Letter which increased the PPI to
0.75%  upon  maturity.  This  right  constituted  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.

Following  Curetis’  insolvency  filing,  on  November  20,  2023,  Curetis  received  a  termination  notice  from  the  EIB  terminating  the  Standstill  Agreement
effective as of November 20, 2023. On December 4, 2023, the Company received a notice from the EIB stating that Curetis is in default of the Finance
Contract as a result of, among other things, Curetis’ failure to repay when due certain outstanding indebtedness under the Finance Contract. Pursuant to that
certain Guarantee and Indemnity Agreement, dated July 9, 2020, between the EIB and the Company, the EIB demanded that the Company, as guarantor,
immediately repay the EIB all amounts owed to the EIB under the Finance Contract and reserved all its other rights and remedies in connection with the
Finance Contract. The Company determined the fair value of the PPI using the Monte Carlo simulation model as of December 31, 2023, but as the EIB
demanded that OpGen immediately repay the aggregate amount of principal, accrued interest and all other amounts owed, the Company included the PPI
component along with the principal and interest in short-term notes payable as of December 31, 2023.

The fair value of level 3 liabilities measured at fair value on a recurring basis for the years ended December 31, 2023 and 2022 was as follows:

Non-financial assets and liabilities carried at fair value on a recurring basis

The Company does not have any non-financial assets and liabilities measured at fair value on a recurring basis.

Non-financial assets and liabilities carried at fair value on a non-recurring basis

The Company measures its long-lived assets, including property and equipment and intangible assets (including goodwill), at fair value on a non-recurring
basis  when  a  triggering  event  requires  such  evaluation.  During  the  year  ended  December  31,  2023,  the  Company  recorded  impairment  expense  of
$1,231,874  related  to  its  property  and  equipment  (see  Note  3)  and  $849,243  related  to  its  right-of-use  lease  asset  (see  Note  3).  During  the  year  ended
December 31, 2022, the Company recorded impairment expense of $6,940,549 related to its goodwill (see Note 3) and $5,407,699 related to its indefinite-
lived intangible asset (see Note 3).

In 2016, Curetis entered into a contract for an up to €25.0 million senior, unsecured loan financing facility from the EIB. The funding could be drawn in up
to five tranches within 36 months of entry into the contract, under the EIB amendment, and each tranche was to be repaid upon maturity five years after
draw-down.

In April 2017, Curetis drew down a first tranche of €10.0 million from this facility. This tranche had 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,  a  second  tranche  of  €3.0  million  was  drawn  down.  The  terms  and  conditions  are  analogous  to  the  first  one.  In  June  2019,
Curetis drew down a third tranche of €5.0 million from the EIB. In line with all prior tranches, the majority of interest is also deferred until repayment upon
maturity. In return for the EIB waiving the condition precedent of a minimum cumulative equity capital raised of €15.0 million to disburse this €5.0 million
third tranche, the parties agreed on a 2.1% PPI. Upon maturity of the tranche, the 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 the EIB on July 9, 2020, the parties
adjusted the PPI percentage applicable to the third EIB tranche of €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. This right constituted an embedded derivative, which is separated
and measured at fair value with changes being accounted for through income or loss. The EIB debt was measured and recognized at fair value as of the
acquisition date. The fair value of the EIB debt was approximately €14.4 million (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.

On May 23, 2022, the Company and the EIB entered into a Waiver and Amendment Letter (the “2022 EIB Amendment”) relating to the amendment of the
EIB loan facility, between the EIB and Curetis, pursuant to which Curetis borrowed an aggregate amount of €18.0 million in three tranches. The 2022 EIB
Amendment  restructured  the  first  tranche  of  approximately  €13.4  million  (including  accumulated  and  deferred  interest)  of  the  Company’s  outstanding
indebtedness with the EIB. Pursuant to the 2022 EIB Amendment, the Company repaid €5.0 million to the EIB in April 2022. The Company also agreed,
among other things, to amortize the remainder of the debt tranche over the twelve-month period beginning in May 2022. Accordingly, the Company agreed
to pay a monthly amount of approximately €0.7 million through April 2023. The Amendment also provided for an increase of the PPI applicable to the
third tranche under the loan facility from 0.3% to 0.75%. The terms of the second and third tranches of the Company’s indebtedness of €3.0 million and
€5.0 million, respectively, plus accumulated deferred interest, remained unchanged pursuant to the 2022 EIB Amendment. The second tranche became due
and payable by the Company to the EIB in June 2023, and the third tranche will become due and payable in June 2024. As the effective borrowing rate
under the amended agreement is less than the effective borrowing rate under the previous agreement, a concession is deemed to have been granted under
ASC 470-60. As a concession has been granted, the agreement was accounted for as a troubled debt restructuring under ASC 470-60. The amendment did
not result in a gain on restructuring as the future undiscounted cash outflows required under the amended agreement exceed the carrying value of the debt
immediately prior to the amendment.

On  June  26,  2023,  the  Company  announced  that  its  subsidiary  Curetis  and  the  European  Investment  Bank  (“EIB”)  agreed  in  principle  to  certain  terms
relating  to  the  repayment  of  the  second  tranche  of  Curetis’  loan  from  the  EIB  pursuant  to  that  certain  Finance  Contract,  dated  December  12,  2016,  as
amended, by and between Curetis and the EIB (the “Finance Contract”). The second tranche had a principal balance of €3 million plus accumulated and
deferred interest. The second tranche was drawn down in June 2018 and matured on June 22, 2023. On July 4, 2023, the EIB and Curetis entered into a
Standstill Agreement pursuant to which the EIB agreed that, with respect to each default or event of default relating to such second tranche, the EIB would
not take any action or exercise any right under the Finance Contract until the earlier of a restructuring of the second tranche and November 30, 2023. As a
condition to entering into the Standstill Agreement, Curetis paid the EIB a partial payment of interest on the second tranche of €1 million on June 22, 2023.
In addition, Curetis agreed to certain undertakings during the standstill period, including the delivery of a rolling cash flow forecast and to cause a third-
party restructuring expert to prepare and deliver a restructuring opinion to the EIB. EIB could terminate the Standstill Agreement upon notice to Curetis if,
among other customary termination rights, Curetis or the guarantors fail to comply with any undertakings in the Standstill Agreement, the third party expert
determines  that  there  are  no  prospects  for  a  successful  restructuring  of  the  second  tranche  and  that  it  therefore  will  be  unable  to  issue  a  restructuring
opinion, or the cash flow forecast shows a negative liquidity shortfall during the specified period.

On November 20, 2023, Curetis received a termination notice from the EIB terminating the Standstill Agreement effective as of November 20, 2023. The
EIB’s termination notice stated that the termination of the Standstill Agreement was as a result of and in connection with certain defaults of the Standstill
Agreement arising from, among other related reasons, Curetis’ and Ares’ entry into insolvency proceedings. On December 4, 2023, the Company received
a notice from the EIB stating that Curetis is in default of the Finance Contract as a result of, among other things, Curetis’ failure to repay when due certain
outstanding  indebtedness  under  the  Finance  Contract.  In  its  notice,  the  EIB  stated  that,  as  of  November  16,  2023,  the  aggregate  amount  of  principal,
accrued interest and all other amounts owed by Curetis to the EIB under the Finance Contract was approximately 9.66 million euro and that interest will
continue  to  accrue  in  accordance  with  the  Finance  Contract  until  all  amounts  owed  are  paid  in  full.  Pursuant  to  that  certain  Guarantee  and  Indemnity
Agreement, dated July 9, 2020 (the “Guaranty”), between the EIB and the Company, the EIB demanded that the Company, as guarantor, immediately repay
the EIB all amounts owed to the EIB under the Finance Contract and reserved all of its other rights and remedies in connection with the Finance Contract.
As  of  the  year  ended  December  31,  2023,  the  Guaranty  remained  unpaid  and  outstanding,  with  the  liability  reflected  on  the  Company’s  financial
statements, which was previously on Curetis’ balance sheet.

In  connection  with  the  Company’s  entry  into  the  March  2024  Purchase  Agreement  with  David  E.  Lazar  on  March  25,  2024,  the  Company  entered  into
settlement  agreements  with  each  of  the  EIB  and  Curetis  and  Curetis’  trustee  in  insolvency,  pursuant  to  which  the  parties  agreed  to  settle  outstanding
liabilities  amongst  the  parties.  Pursuant  to  the  settlement  agreements,  following  the  final  closing  of  the  transactions  contemplated  by  the  March  2024
Purchase Agreement, the Company will pay $2.0 million of the proceeds to settle all outstanding debt of the Company to each of EIB and Curetis. The
settlement agreement with EIB also terminated the Guaranty (see Note 12).

As  of  December  31,  2023,  the  outstanding  borrowings  under  all  tranches  were  €9.8  million  (approximately  $10.9  million),  including  deferred  interest
payable at maturity of €1.5 million (approximately $1.7 million).

Total interest expense (including amortization of debt discounts and financing fees) on all debt instruments was $1,838,933 and $3,256,410 for the years
ended December 31, 2023 and 2022, respectively.

Note 7 - Stockholders’ Equity

As of December 31, 2023, the Company had 100,000,000 shares of authorized common stock and 1,282,686 shares issued and outstanding, and 10,000,000
shares of authorized preferred stock, of which 250 were issued and outstanding.

Following receipt of approval from stockholders at a special meeting of stockholders held on November 30, 2022, the Company filed an amendment to its
Amended and Restated Certificate of Incorporation to effect a reverse stock split of the issued and outstanding shares of common stock, at a ratio of one
share for twenty shares, and the reverse stock split was effective January 5, 2023. All share amounts and per share prices in this Annual Report have been
adjusted to reflect the reverse stock split.

Following  receipt  of  approval  from  stockholders  at  a  special  meeting  of  stockholders  held  on  May  9,  2024,  the  Company  filed  an  amendment  to  its
Amended and Restated Certificate of Incorporation to effect a reverse stock split of the issued and outstanding shares of common stock, at a ratio of one
share  for  ten  shares,  and  the  reverse  stock  split  was  effective  May  20,  2024.  All  share  amounts  and  per  share  prices  in  this  Annual  Report  have  been
adjusted to reflect the reverse stock split (see Note 12).

On June 24, 2022, the Company entered into an At-the-Market, or ATM, Offering Agreement (the “2022 ATM Agreement”) with H.C. Wainwright & Co.,
LLC (“Wainwright”), 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 $10.65  million  of  shares  of  the  Company’s  common  stock  through  Wainwright.  As  of  December  31,  2022,  the  Company  sold  8,574
shares under the 2022 ATM Agreement totaling $1.03 million in gross proceeds and $0.99 million in net proceeds. The Company did not sell any shares
under the 2022 ATM Agreement in 2023.

On  October  3,  2022,  the  Company  closed  a  registered  direct  offering  of  shares  of  common  stock  and  Series  C  Mirroring  Preferred  Stock  pursuant  to  a
securities  purchase  agreement  entered  into  with  a  certain  institutional  investor.  In  the  offering,  the  Company  agreed  to  issue  and  sell  to  the  investor  (i)
26,800 shares of the Company’s common stock, par value $0.01 per share, (ii) 33,810 shares of the Company’s Series C Mirroring Preferred Stock, par
value $0.01 per share and stated value of $0.01 per share, and (iii) pre-funded warrants to purchase an aggregate of 21,500 shares of common stock. Each
share of common stock was sold at a price of $70.00 per share, each share of preferred stock was sold at a price of $0.01 per share, and each pre-funded
warrant  was  sold  at  an  offering  price  of  $68.00  per  share  underlying  such  pre-funded  warrants,  for  aggregate  gross  proceeds  of  $3.34  million  before
deducting  the  placement  agent’s  fees  and  the  offering  expenses,  and  net  proceeds  of  $3.04  million.  Under  the  purchase  agreement,  the  Company  also
agreed  to  issue  and  sell  to  the  investor,  in  a  concurrent  private  placement,  warrants  to  purchase  an  aggregate  of  48,300  shares  of  common  stock.  In
connection with the offering, the Company also entered into a warrant amendment agreement with the investor pursuant to which the Company agreed to
amend  certain  existing  warrants  to  purchase  up  to  74,150  shares  of  common  stock  that  were  previously  issued  to  the  investor  in  2018  and  2021,  with
exercise prices ranging from $410.00 to $13,000.00  per  share  as  a  condition  to  their  purchase  of  the  securities  in  the  offering,  as  follows:  (i)  lower  the
exercise price of the investor’s existing warrants to $75.40 per share, (ii) provide that the existing warrants, as amended, will not be exercisable until six
months following the closing date of the offering, and (iii) extend the original expiration date of the existing warrants by five and one-half years following
the close of the offering. The increase in fair value resulting from the warrant modifications is accounted for as an equity issuance cost, resulting in a debit
and credit to additional paid in capital for approximately $1.8 million. As of December 31, 2022, all 21,500 pre-funded warrants were exercised and all
33,810  shares  of  the  Company’s  Series  C  Mirroring  Preferred  Stock  were  automatically  cancelled  and  ceased  to  be  outstanding  following  receipt  of
stockholder  approval  for  the  Company’s  reverse  stock  split  on  November  30,  2022.  In  connection  with  the  Company’s  best-efforts  public  offering
consummated in May 2023, the Company amended the exercise price of the existing warrants to $7.785 per share.

On January 11, 2023, the Company closed a best-efforts public offering pursuant to a securities purchase agreement with a certain institutional investor for
the purchase of (i) 32,121 shares of the Company’s common stock, par value $0.01 per share, (ii) pre-funded warrants to purchase up to an aggregate of
226,500 shares of common stock (the “Pre-funded Warrants”), (iii) Series A-1 common warrants to purchase an aggregate of 258,621 shares of common
stock (the “Series A-1 Warrants”), and (iv) Series A-2 common warrants to purchase an aggregate of 258,621 shares of common stock (the “Series A-2
Warrants,” and together with the Series A-1 Warrants, the “Common Warrants”). Each share of common stock and accompanying Common Warrants were
sold at a price of $29.00 per share and accompanying Common Warrants, and each Pre-funded Warrant and accompanying Common Warrants were sold at
an  offering  price  of  $28.90  per  share  underlying  such  Pre-funded  Warrants  and  accompanying  Common  Warrants,  for  aggregate  gross  proceeds  of
approximately $7.5 million before deducting the placement agent’s fees and the offering expenses, and net proceeds of approximately $6.9  million.  The
Common Warrants have an exercise price of $26.50 per share. The Series A-1 Warrants were immediately exercisable upon issuance, and will expire five
years following the issuance date. The Series A-2 Warrants were immediately exercisable upon issuance, and will expire eighteen months following the
issuance date. Subject to certain ownership limitations described in the Pre-funded Warrants, the Pre-funded Warrants were immediately exercisable and
could be exercised at a nominal consideration of $0.10 per share of common stock any time until all the Pre-funded Warrants are exercised in full. All Pre-
funded  Warrants  were  exercised  by  February  15,  2023.  In  connection  with  the  Company’s  best-efforts  public  offering  consummated  in  May  2023,  the
Company amended the exercise price of the Common Warrants to $7.785 per share.

On  May  4,  2023,  the  Company  closed  a  best-efforts  public  offering  pursuant  to  a  securities  purchase  agreement  with  a  certain  institutional  investor,
pursuant  to  which  the  Company  issued  and  sold  to  the  Investor  (i)  60,500  shares  of  the  Company’s  common  stock,  par  value  $0.01 per share, (ii) pre-
funded warrants to purchase up to an aggregate of 389,083 shares of common stock, and (iii) common warrants to purchase up to an aggregate of 449,583
shares  of  common  stock.  Each  share  of  common  stock  and  accompanying  common  warrant  was  sold  at  a  price  of  $7.785 per share and accompanying
common warrant, and each pre-funded warrant and accompanying common warrant was sold at an offering price of $7.685 per share underlying such pre-
funded warrant and accompanying common warrant, for aggregate gross proceeds of approximately $3.5 million and net proceeds of approximately $3.0
million. The common warrants have an exercise price of $7.785 per share and will be exercisable beginning on the date of stockholder approval of the
exercisability of the warrants under Nasdaq rules or may be exercised through October 26, 2023, pursuant to the Warrant Inducement Agreement entered
into on October 12, 2023. Pursuant to amendment agreements entered into by the Company and Holder on October 26, 2023 and February 7, 2024, the
Company agreed to initially extend the offer period until December 31, 2023, and subsequently extend the offer period until April 30, 2024 (see Note 12).
In  order  to  permit  the  exercise  of  the  Existing  Warrants  pursuant  to  the  rules  of  the  Nasdaq  Capital  Market,  the  Holder  agreed  to  pay  as  additional
consideration  $0.25  per  share  of  common  stock  issued  upon  exercise  of  the  Existing  Warrants.  The  common  warrants  not  exercised  as  part  of  the
Inducement Agreement will expire on the five-year anniversary of the date of such stockholder approval. Each pre-funded warrant has an exercise price per
share of common stock equal to $0.10 per share and may be exercised at any time until the pre-funded warrants are exercised in full. In connection with the
offering,  the  Company  also  entered  into  a  warrant  amendment  agreement  with  the  investor  pursuant  to  which  the  Company  amended  certain  existing
warrants to purchase up to 639,691 shares of common stock that were previously issued in 2018, 2021, 2022 and 2023 to the investor, with exercise prices
ranging from $26.50 to $75.40 per share, in consideration for their purchase of the securities in the offering, as follows: (i) lower the exercise price of the
existing warrants to $7.785 per share, (ii) provide that the existing warrants, as amended, will not be exercisable until the receipt of stockholder approval
for the exercisability of the common warrants in the offering, and (iii) extend the original expiration date of the existing warrants by five years following
the receipt of such stockholder approval. The increase in fair value resulting from the warrant modifications is accounted for as an equity issuance cost,
resulting in a debit and credit to additional paid in capital of approximately $0.3 million. As of December 31, 2023, the Holder exercised 200,000 shares of
Common Stock under the existing warrants pursuant to the Inducement Agreement for aggregate gross proceeds to the Company of $2.057 million before
deducting financial advisory fees and other expenses payable by the Company.

On October 11, 2023, the Company entered into a Preferred Stock Purchase Agreement (the “Purchase Agreement”) with a single investor (the “Investor”),
pursuant to which the Company agreed to issue and sell to the Investor in a private placement (the “Private Placement”) 1,000 shares of the Company’s
Series D Preferred Stock, par value $0.01 per share (the “Preferred Stock”). Each share of preferred stock was agreed to sell at a price of $1,000 per share
for expected aggregate gross proceeds of $1.0 million before deducting offering expenses. The Private Placement was conducted in connection with the
negotiation  of  a  potential  strategic  transaction  involving  the  Company  and  the  Investor.  The  Company  intended  to  use  the  proceeds  of  the  Private
Placement to fund the Company’s operations while it pursued a potential strategic transaction with the Investor. Pursuant to the Purchase Agreement, the
Company filed a certificate of designation (the “Certificate of Designation”) with the Secretary of State of the State of Delaware designating the rights,
preferences and limitations of the shares of preferred stock on October 11, 2023. The Certificate of Designation provides that the shares of preferred stock
have a stated value of $1,000 per share and are convertible into shares of common stock, par value $0.01 per share of the Company at a price of $4.09 per
share, subject to adjustment in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications, or similar events
affecting the common stock. The preferred stock may be converted at any time at the option of the holder. Notwithstanding the foregoing, the Certificate of
Designation provides that in no event will the preferred stock be convertible into common stock in a manner that would result in the holder, its permitted
transferees and affiliates holding more than 19.99% (together with any shares of common stock otherwise held by the Investor, its permitted transferees and
their affiliates) of the then issued and outstanding common stock (the “Ownership Limitation”), prior to the date that the Company’s stockholders approve
the issuance of shares of common stock to the holder upon conversion of the preferred stock (the “stockholder approval”). Upon receipt of stockholder
approval,  the  shares  of  preferred  stock  will  automatically  be  converted  into  shares  of  common  stock  without  further  action  of  the  holder  thereof.  The
Investor  funded  $250,000  of  the  expected  aggregate  gross  proceeds  of  $1.0  million  before  deducting  offering  expenses  on  November  14,  2023.  On
December 13, 2023, in coordination with the Investor, the Company issued to the Investor 250 shares of Series D Preferred Stock in consideration for the
partial payment. As of December 31, 2023, all 250 Series D Preferred Shares remain outstanding and the remaining $750,000 of the purchase price remains
unpaid. The Company reserves all rights and remedies arising from the Investor’s failure to close the transaction and the Investor will continue to be in
breach of the Purchase Agreement until the remaining amount is paid in full.

On October 12, 2023, the Company entered into a warrant inducement agreement (the “Inducement Agreement”) with a holder (the “Holder”) of certain
existing warrants (the “Existing Warrants”) to purchase shares of common stock, par value $0.01 per share, of the Company. Pursuant to the Inducement
Agreement,  the  Holder  agreed  to  exercise  for  cash  their  Existing  Warrants  to  purchase  up  to  1,089,274  shares  of  the  Company’s  common  stock  at  an
exercise price of $7.785 per share, the exercise price per share of the Existing Warrants, during the period from the date of the Inducement Agreement until
7:30  a.m.,  Eastern  Time,  on  October  26,  2023.  Pursuant  to  amendment  agreements  entered  into  by  the  Company  and  Holder  on  October  26,  2023  and
February 7, 2024, the Company agreed to initially extend the offer period until December 31, 2023, and subsequently extend the offer period until April 30,
2024 (see Note 12). In order to permit the exercise of the Existing Warrants pursuant to the rules of the Nasdaq Capital Market, the Holder agreed to pay as
additional consideration $0.25 per share of common stock issued upon exercise of the Existing Warrants. In consideration of the Holder’s agreement to
exercise the Existing Warrants in accordance with the Inducement Agreement, the Company agreed to issue new warrants (the “Inducement Warrants”) to
purchase shares of common stock equal to 100% of the number of shares of common stock issued upon exercise of the Existing Warrants (the “Inducement
Warrant Shares”). The Inducement Warrants will have an exercise price of $3.36 per share and will be exercisable on the six-month anniversary of the date
of issuance and expire on the five-year anniversary of the Inducement Warrant’s first becoming exercisable. As of December 31, 2023, the Holder exercised
200,000  shares  of  Common  Stock  under  the  existing  warrants  pursuant  to  the  Inducement  Agreement  for  aggregate  gross  proceeds  to  the  Company  of
$2.057 million before deducting financial advisory fees and other expenses payable by the Company.

Stock options

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

In April 2015, the Company 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 initial public offering in May 2015. Following the effectiveness
of  the  2015  Plan,  no  further  grants  will  be  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.

Under the 2015 Plan, the aggregate number of shares of the common stock authorized for issuance may not exceed (1) 271 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. Following Board of Director approval, 11,600 shares were automatically added to the 2015 Plan in 2023. 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, 2023, 11,852 shares remain available for issuance under the 2015 Plan.

For the years ended December 31, 2023 and 2022, the Company recognized share-based compensation expense as follows:

average period of 1.2 years.

carryforwards, research and development (“R&D”) credits, and the deconsolidation of subsidiaries. The Company’s net deferred tax assets at December 31,
2023 and 2022 have been offset by a valuation allowance of $110,358,421 and $106,060,462, 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,  2023  and  2022  are  as

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, 2023 and 2022. Accordingly, a
valuation allowance of $110.4 million and $106.1 million has been recorded to offset the net deferred tax assets.

The Company has federal NOL carryforwards of $241,110,447 and $232,682,072 at December 31, 2023 and 2022, respectively. The NOL carryforwards
incurred prior to 2018 began expiring in 2023. 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 carryforwards 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 carryforwards 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.

The  Tax  Act  amended  IRC  Section  174  to  require  capitalization  of  all  research  and  development  ("R&D")  costs  incurred  in  tax  years  beginning  after
December  31,  2021.  These  costs  are  required  to  be  amortized  over  five  years  if  the  R&D  activities  are  performed  in  the  U.S.,  or  over  15  years  if  the
activities were performed outside the U.S. The Company capitalized approximately $23 thousand of R&D expenses incurred as of December 31, 2023.

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 framework agreement, which had an initial term of 36 months and was subsequently extended to January 31, 2025, Ares Genetics
and Sandoz intended 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,  aimed  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  have  already  developed  resistance  against  multiple  treatment
options. In the longer-term, the platform was 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.
Following Ares Genetics’ insolvency filing, the Company will no longer benefit from this framework agreement.

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 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. Following the insolvency filings of Curetis and Ares Genetics, the Company will no longer benefit
from this strategic licensing agreement.

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 $7,318 and
$9,546 for the years ended December 31, 2023 and 2022, respectively. Following Ares Genetics’ insolvency filing, the Company will no longer generate
licensed product sales or sublicense revenues nor incur royalty expenses related to the Siemens GEAR assets.

Foundation for Innovative New Diagnostics (FIND)

On September 20, 2022, Curetis GmbH and FIND entered into a research and development collaboration agreement for a total amount due to Curetis of
€0.7 million to develop a simple to use molecular diagnostic test for identification of pathogens and antibiotic resistances in positive blood cultures for
deployment in low- and middle-income countries (“LMICs”). On April 4, 2023, the Company entered into an amendment to its research and development
collaboration agreement with FIND to expand the deliverables in exchange for an additional €0.13 million in milestone payments (“Amendment 1”). The
additional  deliverables  were  completed  by  June  30,  2023.  Following  successful  completion  of  the  feasibility  phase  of  the  collaboration,  including  the
additional deliverables, FIND and Curetis, on August 1, 2023, extended the research and development collaboration agreement through May 31, 2024, to
include  AMR  assay  and  cartridge  development,  analytical  testing,  and  software  development  for  an  additional  €0.5  million  (“Amendment  2”).  The
Company  recognized  revenues  of  $0.6  million  and  $0.3  million  from  the  FIND  collaboration  for  the  years  ended  December  31,  2023  and  2022,
respectively. Following Curetis’ insolvency filing, the Company will no longer benefit from this collaboration agreement.

Note 12 - Subsequent Events

The Company evaluates subsequent events and transactions that occur after the balance sheet date up to the date that the consolidated financial statements
are issued.

Other than as disclosed in this Note 12 and as was disclosed in Notes 1, 2, 6, and 7 to the accompanying consolidated financial statements, there have been
no subsequent events that require adjustment or disclosure in the accompanying consolidated financial statements.

On February 7, 2024, the Company and a holder (the “Holder”) of certain existing warrants (the “Existing Warrants”) to purchase shares of common stock,
par value $0.01 per share (the “Common Stock”), of the Company agreed to amend (the “Amendment”) that certain warrant inducement agreement entered
into by the Company and the Holder on October 12, 2023 and amended on October 26, 2023 (as amended, the “Inducement Agreement”). Pursuant to the
Inducement  Agreement,  the  Holder  agreed  to  exercise  for  cash  their  Existing  Warrants  to  purchase  up  to  1,089,274  shares  of  the  Company’s  Common
Stock at an exercise price of $7.785 per share, the exercise price per share of the Existing Warrants, during the period from the date of the Inducement
Agreement  until  December  31,  2023.  As  of  December  31,  2023,  the  Holder  exercised  200,000  shares  of  Common  Stock  under  the  Existing  Warrants
pursuant to the Inducement Agreement for aggregate gross proceeds to the Company of $2.057 million before deducting financial advisory fees and other
expenses payable by the Company. The Holder did not exercise any additional Existing Warrants after December 31, 2023. Except for the extension of the
offer period pursuant to the Amendment, the terms and conditions of the Inducement Agreement remain unchanged. Since the warrant inducement period
was not extended beyond April 30, 2024, the Company is required to hold a stockholders’ meeting to obtain approval for the exercisability of the existing
common warrants within 70 days of the end of the extension period.

As  previously  disclosed,  on  December  11,  2023,  the  Company  requested  a  hearing  by  the  Nasdaq  Hearings  Panel  (the  “Panel”)  of  The  Nasdaq  Stock
Market LLC (“Nasdaq”) to appeal the Nasdaq listing staff’s (the “Staff”) determination to delist the Company’s securities as a result of the failure of the
Company’s common stock to comply with the minimum bid price requirement of Nasdaq Listing Rule 5550(a)(2) (the “Bid Price Rule”). In response to the
Company’s request, on February 9, 2024, the Company received written notification (the “Notice”) from Nasdaq notifying the Company that the Panel had
granted the Company’s request for an additional period, during which the Company will remain listed on Nasdaq, to regain compliance with the Bid Price
Rule.  Pursuant  to  the  Notice,  the  Panel  granted  the  Company  an  additional  period  until  June  3,  2024  to  regain  compliance.  The  extension  is  subject  to
certain conditions specified by the Panel in the Notice. While the Company intends to comply with such conditions, there can be no assurance that the
Company will be able to regain or remain in compliance with the applicable Nasdaq listing requirements on an ongoing basis or that the Panel will afford
the Company additional time to achieve compliance.

On  March  25,  2024,  the  then-current  members  of  the  Board  of  Directors  (the  “Board”)  approved  an  increase  in  the  size  of  the  Board  and  appointed
Mr. Lazar to the Board. On March 25, 2024, in connection with the initial closing of the transactions contemplated by the March 2024 Purchase Agreement
noted below, the then-current members of the Board of Directors (the “Board”) of the Company voted to appoint Avraham Ben-Tzvi, David Natan, and
Matthew C. McMurdo as new, independent directors. The then-current members of the Board thereafter resigned effective as of March 25, 2024. The initial
term as director for Messrs. Ben-Tzvi, Natan, McMurdo, and Lazar will expire at the Company’s 2025 annual meeting of stockholders. At the time of the
election,  none  of  the  new  directors  were  appointed  to  any  committees  of  the  Board  of  Directors.  The  Board  deemed  Mr.  Ben-Tzvi,  Mr.  Natan,  and
Mr. McMurdo as independent pursuant to Rule 5605 of the Nasdaq Listing Requirements. The Board intends to engage Mr. Lazar as an executive officer of
the Company, and thereby does not deem him independent.

F-37

 
 
 
 
 
 
 
 
On March 25, 2024, the Company entered into a securities purchase agreement (the “March 2024 Purchase Agreement”) with David E. Lazar, pursuant to
which the Company agreed to sell 3,000,000 shares of Series E Convertible Preferred Stock (“Series E Preferred Stock”) to Mr. Lazar at a price of $1.00
per  share  for  aggregate  gross  proceeds  of  $3.0  million.  In  connection  with  the  transactions  contemplated  by  the  March  2024  Purchase  Agreement,  the
members of the Board of Directors prior to the closing of such transactions resigned, and a new Board of Directors was appointed, of which Mr. Lazar was
appointed Chairman. On March 25, 2024, Mr. Lazar paid $200,000 at the initial closing of the transactions under the March 2024 Purchase Agreement in
exchange  for  200,000  shares  of  Series  E  Preferred  Stock.  Mr.  Lazar  subsequently  paid  $200,000  and  $150,000  on  April  5,  2024  and  April  23,  2024,
respectively, in exchange for an additional 350,000 shares of Series E Preferred Stock. Mr. Lazar is expected to fund the remaining $2.45 million in early
June  2024,  at  which  time  he  will  receive  the  remaining  2.45  million  shares  of  Series  E  Preferred  Stock.  Each  share  of  Series  E  Preferred  Stock  is
convertible  into  2.4  shares  of  the  Company’s  common  stock  (“Common  Stock”);  provided,  that,  in  no  event,  will  the  Series  E  Preferred  Stock  be
convertible into Common Stock in a manner that would result in Mr. Lazar or his transferees or their affiliates holding more than the lesser of (i) 19.99%
(together  with  any  other  shares  of  Common  Stock  otherwise  held  by  them  or  their  affiliates)  and  (ii)  such  lower  percentage  as  may  be  required  by
applicable  stock  exchange  rules  of  the  then  issued  and  outstanding  Common  Stock  (the  “Ownership  Limitation”),  prior  to  the  date  that  the  Company’s
stockholders  approve  the  issuance  of  shares  of  Common  Stock  to  Mr.  Lazar  upon  conversion  of  the  Series  E  Preferred  Stock.  In  connection  with  the
transactions contemplated by the March 2024 Purchase Agreement, the Company entered into settlement agreements (the “Settlement Agreements”) with
each of the European Investment Bank (“EIB”) and Curetis GmbH, the Company’s subsidiary (“Curetis”), and Curetis’ trustee in insolvency, pursuant to
which the Company settled outstanding liabilities amongst the parties. Pursuant to the settlement agreements and the March 2024 Purchase Agreement,
following the final closing of transactions contemplated by the March 2024 Purchase Agreement, the Company will pay $2.0 million of the proceeds to
settle  all  outstanding  debt  of  the  Company  to  each  of  EIB  and  Curetis.  The  settlement  agreement  with  EIB  also  terminated  that  certain  Guarantee  and
Indemnity Agreement, dated as of July 9, 2020, by and between the EIB and the Company, pursuant to which the Company had guaranteed all of Curetis’
debt to EIB.

On  March  26,  2024,  the  Company  entered  into  an  Inducement  Offer  to  Amend  Common  Stock  Purchase  Warrants  (the  “Offer”)  with  an  investor  (the
“Investor”). Pursuant to the Offer, the investor agreed to waive certain rights that would otherwise have been triggered under their warrants as a result of
the transactions contemplated by the March 2024 Purchase Agreement, in exchange for the Company entering into the March 2024 Purchase Agreement.

Effective April 1, 2024, the Company entered into a lease assignment agreement where the Company assigned, transferred, set over and conveyed to an
assignee all its estate, right, title and interest in and to the lease at its Rockville, Maryland headquarters. The Company’s security deposit will remain with
the landlord and be repaid over time as agreed upon with the assignee.

On  April  11,  2024,  the  Company  entered  into  an  Employment  Agreement  with  David  E.  Lazar.  Pursuant  to  the  Employment  Agreement,  the  Company
engaged Mr. Lazar to act as its Chief Executive Officer (“CEO”). Mr. Lazar will have the customary powers and responsibilities of a CEO of a corporation
of the size and type of the Company. Effective April 1, 2024, Mr. Lazar shall be paid a base salary of $406,000 per annum, which shall be deferred and
accrued until the Company’s compensation committee determines that the Company is sufficiently liquid to pay the accrued salary. Under the Agreement,
Mr.  Lazar  will  also  be  eligible  for  certain  annual  bonuses,  annual  incentive  bonuses,  and  special  bonuses.  The  Agreement  has  a  three  (3)  year  term.
Mr. Lazar also serves as the Chairman of the Board of Directors of the Company.

On April 18, 2024, the Company received a notice from The Nasdaq Stock Market LLC (“Nasdaq”) stating that the Company was delinquent in filing its
Annual Report on Form 10-K for the fiscal year ended December 31, 2023 (the “Form 10-K”) and was therefore not in compliance with Nasdaq Listing
Rule 5250(c)(1). The notice indicated that such delinquency serves as an additional basis for delisting the Company’s securities in addition to the failure to
comply with the Minimum Bid Price Rule described previously. In accordance with the notice, the Company submitted its response to the Nasdaq Hearings
Panel regarding such delinquency and the Company’s plan to cure such delinquency by June 3, 2024, the additional period to regain compliance granted by
such Nasdaq Hearings Panel. The Company plans to file its Form 10-K as soon as practicable; however, no assurance can be given as to the definitive date
on which such reports will be filed or the final decision of the Nasdaq Hearings Panel regarding a delisting of the Company’s securities. As with the prior
notices, the most recent notice from Nasdaq has no immediate effect on the listing of the Company’s securities on The Nasdaq Capital Market.

On April 22, 2024, UHY LLP (“UHY”), the Company’s then-current independent public accounting firm, notified the Company that UHY would resign as
the Company’s auditor effective as of April 22, 2024. During the period of UHY’s engagement, which commenced in March 2023, UHY did not provide
any  report  on  the  financial  statements  of  the  Company.  During  the  fiscal  years  ended  December  31,  2023  and  2022  and  the  subsequent  interim  period
through April 22, 2024, there were no: (1) disagreements with UHY on any matter of accounting principles or practices, financial statement disclosure, or
auditing scope or procedures, which disagreements, if not resolved to their satisfaction, would have caused them to make reference in connection with their
opinion  to  the  subject  matter  of  the  disagreement,  or  (2)  reportable  events  under  Item  304(a)(1)(v)  of  Regulation  S-K.  In  light  of  such  resignation,  on
April 23, 2024, the Company engaged Beckles & Co., Inc. (“Beckles”) to serve as the Company’s independent registered public accounting firm for the
fiscal  year  ending  December  31,  2023  and  upcoming  interim  period.  The  appointment  of  Beckles  as  the  Company’s  independent  registered  public
accounting firm was approved by the Company’s Board of Directors.

On April 23, 2024, the Company entered into a letter agreement with Camtech Pte Ltd, a Singaporean family office (“Camtech”), for the sale of certain of
the Company’s inventory and customer contracts for its Unyvero products. The transaction was entered into following the prior acquisition by Camtech in
April 2024 of the assets from the Company’s subsidiary, Curetis GmbH (“Curetis”), as part of Curetis’ insolvency proceedings. The purchase price for the
transaction is $218,000, and the transaction closed in May 2024. As part of such letter agreement, the Company also offered Camtech the opportunity to
purchase  its  remaining  Unyvero  inventory  and  assets  for  up  to  an  additional  $176,000.  Until  such  sale  for  the  remaining  inventory  is  completed,  the
Company will maintain commercial operations and service support for the Unyvero systems. The foregoing transactions are part of the Company’s planned
exit from its Unyvero business, as the Company continues to seek strategic alternatives.

On May 9, 2024, the Company held a special meeting of stockholders (the “Special Meeting”). The Company’s stockholders voted on three proposals, each
of which was described in the Company’s proxy statement for the Special Meeting dated May 9, 2024. At the Special Meeting, shares of the Company’s
capital stock representing 14,795,642 votes out of a total of 26,435,902 votes of the Company’s capital stock, as of April 26, 2024, the record date for the
Special Meeting, were represented in person or by proxy at the Special Meeting. All three of the following proposals were voted upon and approved at the
Special Meeting. Proposal 1 approved (i) the issuance to David E. Lazar of the common stock issuable upon the conversion of the Company’s Series E
Preferred Stock in excess of applicable beneficial ownership limitations, the issuance of which would result in a “change of control” under the rules of The
Nasdaq  Capital  Market  and  (ii)  an  amendment  of  the  Certificate  of  Designation  for  the  Series  E  Preferred  Stock  removing  such  ownership  limitations.
Proposal 2 approved the amendment to the Company’s Amended and Restated Certificate of Incorporation, as amended (the “Charter”), to effect a reverse
stock split at a ratio not less than two-to-one and not more than ten-to-one, such ratio and the implementation and timing of such reverse stock split to be
determined  in  the  discretion  of  our  Board  of  Directors.  Proposal  3  approved  of  an  adjournment  of  the  Special  Meeting  to  a  later  date,  if  necessary  or
appropriate, to permit further solicitation and vote of proxies in the event that there are insufficient votes for, or otherwise in connection with, Proposals 1
and 2. Following the approval of the amendment of the Certificate of Designation, the Company filed the amendment with the Secretary of State of the
State of Delaware on May 9, 2024. Except for the removal of the Ownership Limitation, the amendment does not make any other changes to the Certificate
of Designation.

On May 16, 2024, the Company entered into an Amendment Agreement (the “Amendment Agreement”) with the European Investment Bank (the “EIB”)
relating to the previously disclosed settlement agreement, dated March 25, 2024, by and between the Company and the EIB (the “Settlement Agreement”).
As previously disclosed, in connection with the sale and issuance of shares of preferred stock of the Company to David E. Lazar (the “Private Placement”),
the  Company  entered  into  the  Settlement  Agreement  with  the  EIB,  which  provided,  among  other  things,  for  the  settlement  of  outstanding  liabilities
between the EIB, the Company and the Company’s subsidiary, Curetis GmbH (“Curetis”), and the termination of the Company’s guarantee of Curetis’ debt
to EIB. Pursuant to the Settlement Agreement, the Company agreed to pay a portion of the proceeds (the “Settlement Amount”) of the Private Placement to
the EIB upon the final closing of the Private Placement. As a result of the delay of the final closing of the Private Placement due to the delay in filing the
Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023, the Company and the EIB entered into the Amendment Agreement
in order to extend the timing for the payment of the Settlement Amount to June 3, 2024.

On May 16, 2024, the Company announced that it intended to effect a reverse stock split (the “Reverse Stock Split”) of its issued and outstanding shares of
common stock, par value $0.01 per share (the “Common Stock”), at a ratio of 1 post-reverse-split share for every 10 pre-reverse-split shares (the “Reverse
Split  Ratio”).  The  Common  Stock  will  continue  to  be  traded  on  The  Nasdaq  Capital  Market  under  the  symbol  “OPGN”  and  began  trading  on  a  split-
adjusted basis when the markets opened on Monday, May 20, 2024, under a new CUSIP number, 68373L505. The Company filed an Amendment to the
Company’s Amended and Restated Certificate of Incorporation, as amended, with the Secretary of State of the State of Delaware on May 17, 2024, and the
Reverse Stock Split became effective in accordance with the terms of the Amendment on May 20, 2024 (the “Effective Time”). The Reverse Stock Split
impacts all holders of OpGen’s common stock proportionally and will not impact any stockholders’ percentage ownership of common stock (except to the
extent the Reverse Stock Split results in any stockholder owning a fractional share). No fractional shares will be issued in connection with the Reverse
Stock Split. Stockholders of record who would otherwise be entitled to receive a fractional share will receive a whole share in lieu of the fractional share.

On May 20, 2024, the Company received a notice from The Nasdaq Stock Market LLC (“Nasdaq”) stating that the Company was delinquent in filing its
Quarterly  Report  on  Form  10-Q  for  the  period  ended  March  31,  2024  (the  “Form  10-Q”)  and  was  therefore  not  in  compliance  with  Nasdaq  Listing
Rule 5250(c)(1). The notice indicated that such delinquency serves as an additional basis for delisting the Company’s securities in addition to the failure to
comply with the Minimum Bid Price Rule as well as the failure to timely file its Annual Report on Form 10-K for the fiscal year ended December 31, 2023.
In accordance with the notice, the Company submitted its response to the Nasdaq Hearings Panel regarding such delinquency and the Company’s plan to
cure such delinquency. On May 29, 2024, the Nasdaq Hearings Panel granted the Company’s request for continued listing subject to the Company filing its
Form 10-Q by July 8, 2024. The Company plans to file its Form 10-Q as soon as practicable; however, no assurance can be given as to the definitive date
on which such report will be filed.

OPGEN, INC.

INSIDER TRADING POLICY

Exhibit 19

I. Purpose

This  Insider  Trading  Policy  (the  “Policy”)  provides  guidelines  with  respect  to  transactions  in  the  securities  of  OpGen,  Inc.  (the  “Company”)  and  the
handling of confidential information about the Company and the companies with which the Company does business. The Company’s Board of Directors
has  adopted  this  Policy  to  promote  compliance  with  federal  and  state  securities  laws  that  prohibit  certain  persons  who  are  aware  of  material  nonpublic
information about a company from: (i) trading in securities of that company; or (ii) providing material nonpublic information to other persons who may
trade on the basis of that information.

II. Persons Subject to the Policy

This  Policy  applies  to  all  officers,  all  members  of  the  Board  of  Directors  and  all  employees  of  the  Company  and  its  affiliates  and  subsidiaries.  The
Company may also determine that other persons should and will be subject to this Policy, such as contractors or consultants who have access to material
nonpublic information.

This Policy also applies to your family members who reside with you (including a spouse, a child, a child away at college, stepchildren, grandchildren,
parents,  stepparents,  grandparents,  siblings  and  in-laws),  anyone  else  who  lives  in  your  household,  and  any  family  members  who  do  not  live  in  your
household but whose transactions in the Company’s securities (collectively referred to in this Policy as “Company Securities”) are directed by you or are
subject to your influence or control, such as parents or children who consult with you before they trade in Company Securities (collectively referred to as
“Family Members”). You are responsible for the transactions of these other persons and therefore should make them aware of the need to confer with you
before they trade in Company Securities, and you should treat all such transactions for the purposes of this Policy and applicable securities laws as if the
transactions were for your own account. This Policy does not, however, apply to personal securities transactions of Family Members where the purchase or
sale decision is made by a third party not controlled by, influenced by or related to you or your Family Members.

III. Transactions Subject to the Policy

This Policy applies to transactions in Company Securities, including (but not limited to) the Company’s common stock, options to purchase common stock,
preferred stock, convertible debt and warrants, or any other type of securities that the Company has or may issue, as well as derivative securities that are
not issued by the Company, such as exchange-traded put or call options or swaps relating to the Company Securities. In addition, this Policy applies to
transactions in securities of other companies as described below in more detail under the heading “Statement of Policy.”

This Policy applies to transactions by any entities that you influence or control, including any corporations, partnerships or trusts (collectively referred to as
“Controlled Entities”), and transactions by these Controlled Entities should be treated for the purposes of this Policy and applicable securities laws as if
they were for your own account.

 
 
 
 
 
 
 
 
 
 
 
 
 
IV. Individual Responsibility

Persons subject to this Policy have ethical and legal obligations to maintain the confidentiality of information about the Company and to not engage in
transactions in Company Securities while in possession of material nonpublic information. Each individual is responsible for making sure that he or she
complies  with  this  Policy,  and  that  any  Family  Members  or  Controlled  Entities  whose  transactions  are  subject  to  this  Policy,  as  discussed  below,  also
comply with this Policy. In all cases, the responsibility for determining whether an individual is in possession of material nonpublic information rests with
that individual, and any action on the part of the Company, the legal counsel to the Company or any other employee or director pursuant to this Policy (or
otherwise)  does  not  in  any  way  constitute  legal  advice  or  insulate  an  individual  from  liability  under  applicable  securities  laws.  You  could  be  subject  to
severe legal penalties and disciplinary action by the Company for any conduct prohibited by this Policy or applicable securities laws, as described below in
more detail under the heading “Consequences of Violations.”.

V. Statement of Policy

It is the policy of the Company that no person subject to this Policy, who is aware of material nonpublic information relating to the Company may, directly,
or indirectly through family members or other persons or entities:

1.

2.

3.

engage in transactions in Company Securities, except as otherwise specified in this Policy under the headings “Transactions Not Subject to the
Policy,” “Transactions Not Involving a Purchase or Sale” and “Rule 10b5-1 Plans;”

recommend the purchase or sale of any Company Securities;

disclose material nonpublic information to persons within the Company, also including its affiliates and subsidiaries, whose jobs do not require
them to have that information, or outside of the Company and its affiliates and subsidiaries to other persons, including, but not limited to, family,
friends, business associates, investors and expert consulting firms, unless any such disclosure is made in accordance with the Company’s policies
regarding the protection or authorized external disclosure of information regarding the Company; or

4.

assist anyone engaged in the above activities.

In  addition,  it  is  the  policy  of  the  Company  that  no  person  subject  to  this  Policy  who,  in  the  course  of  working  for  the  Company  or  its  affiliates  and
subsidiaries,  learns  of  material  nonpublic  information  about  a  company  with  which  the  Company  does  business,  including  a  customer,  supplier  or
competitor of the Company, may engage in any of the activities set forth above with respect to such company’s securities until the information becomes
public or is no longer material.

Furthermore, short-term trading of Company Securities may be distracting to a person and may unduly focus such person on the Company’s short-term
stock  market  performance  instead  of  the  Company’s  long-term  business  objectives.  In  addition,  directors  and  officers  are  subject  to  short  swing  profit
forfeiture for purchases and sales (or sales and purchases) within a six-month period. For these reasons, it is the policy of the Company that any director or
officer of the Company, also including its affiliates and subsidiaries, who purchases Company Securities in the open market may not sell any Company
Securities of the same class during the six months following the purchase (or vice versa).

There are no exceptions to this Policy, except as specifically noted herein. Transactions that may be necessary or justifiable for independent reasons (such
as the need to raise money for an emergency expenditure), or small transactions, are not excepted from this Policy. The securities laws do not recognize any
mitigating circumstances, and, in any event, even the appearance of an improper transaction must be avoided to preserve the Company’s reputation for
adhering to the highest standards of conduct.

VI. Definition of Material Nonpublic Information

Material  Information.  Information  is  considered  “material”  if  a  reasonable  investor  would  consider  that  information  important  in  making  a
decision  to  buy,  hold  or  sell  securities.  Any  information  that  could  be  expected  to  affect  the  Company’s  stock  price,  whether  it  is  positive  or  negative,
should be considered material. Determining whether information is material is not always straightforward; rather, materiality is based on an assessment of
all  of  the  facts  and  circumstances  and  is  often  evaluated  by  enforcement  authorities  with  the  benefit  of  hindsight.  While  it  is  not  possible  to  define  all
categories of material information, some examples of information that ordinarily would be regarded as material are (non-exhaustive):

● Projections of future earnings or losses, or other earnings guidance;

● Changes to previously announced earnings guidance, or the decision to suspend earnings guidance;

● Development of significant new products or discoveries;

● Results of significant clinical trials;

● The gain or loss of a significant customer or supplier;

● Major marketing changes;

● A pending or proposed merger, acquisition or tender offer;

● A pending or proposed acquisition or disposition of a significant asset or entities;

● Pending or threatened significant litigation, or the resolution of such litigation;

● A pending or proposed joint venture;

● A change in dividend policy, the declaration of a stock split, or an offering of additional securities;

● Bank borrowings or other financing transactions out of the ordinary course;

● The establishment of a repurchase program for Company Securities;

● A change in the Company’s pricing or cost structure;

● A change in management;

● A Company restructuring;

● Significant related party transactions; and

● A change in auditors or notification that the auditor’s reports may no longer be relied upon.

When Information is Considered Public. Information that has not been disclosed to the public is generally considered to be nonpublic information.
In  order  to  establish  that  the  information  has  been  disclosed  to  the  public,  it  may  be  necessary  to  demonstrate  that  the  information  has  been  widely
disseminated.  Information  generally  would  be  considered  widely  disseminated  if  it  has  been  disclosed  through  the  Dow  Jones  “broad  tape,”  newswire
services, publication in a widely available newspaper, magazine or news website, or public disclosure documents filed with the Securities and Exchange
Commission (“SEC”) that are available on the SEC’s website. By contrast, information would likely not be considered widely disseminated if it is available
only to the Company’s employees, or if it is only available to a select group of analysts, brokers and institutional investors.

Once information is widely disseminated, it is still necessary to afford the investing public with sufficient time to absorb the information. As a general rule,
information  should  not  be  considered  fully  absorbed  by  the  marketplace  until  after  the  second  business  day  after  the  day  on  which  the  information  is
released. If, for example, the Company were to make an announcement at the close of business on a Monday, a person covered by this Policy should not
trade in Company Securities until Thursday. Depending on the particular circumstances, the Company may determine that a longer or shorter period should
apply to the release of specific material nonpublic information.

VII. Special and Prohibited Transactions

The Company has determined that there is a heightened legal risk and/or the appearance of improper or inappropriate conduct if persons subject to this
Policy engage in certain types of transactions. It therefore is the Company’s policy that any persons covered by this Policy may not engage in any of the
following transactions, or should otherwise consider the Company’s preferences as described below:

Short Sales. Section 16(c) of the Securities Exchange Act of 1934 (the “Exchange Act”) prohibits officers and directors from engaging in short
sales. In addition, short sales of Company Securities (i.e., the sale of a security that the seller does not own) may evidence an expectation on the part of the
seller that the securities will decline in value, and therefore have the potential to signal to the market that the seller lacks confidence in the Company’s
prospects.  In  addition,  short  sales  may  reduce  a  seller’s  incentive  to  seek  to  improve  the  Company’s  performance.  For  these  reasons,  short  sales  of
Company Securities are prohibited (Short sales arising from certain types of hedging transactions are governed by the paragraph below entitled “Hedging
Transactions”).

Publicly  Traded  Options.  Given  the  relatively  short  term  of  publicly  traded  options,  transactions  in  options  may  create  the  appearance  that  a
director or officer is trading based on material nonpublic information and focus a director’s or officer’s attention on short-term performance at the expense
of the Company’s long-term objectives. Accordingly, transactions in put options, call options or other derivative securities, on an exchange or in any other
organized market, are prohibited by this Policy (Option positions arising from certain types of hedging transactions are governed by the next paragraph
below.).

Hedging Transactions. Hedging or monetization transactions can be accomplished through a number of possible mechanisms, including through
the  use  of  financial  instruments  such  as  prepaid  variable  forwards,  equity  swaps,  collars  and  exchange  funds.  Such  hedging  transactions  may  permit  a
director or officer to continue to own Company Securities obtained through employee benefit plans or otherwise, but without the full risks and rewards of
ownership. When that occurs, the director or officer may no longer have the same objectives as the Company’s other shareholders. Therefore, directors,
officers and other persons designated by the CEO or CFO (or any other person designated as subject to this Policy) are prohibited from engaging in any
such transactions.

Margin Accounts and Pledged Securities. Securities held in a margin account as collateral for a margin loan may be sold by the broker without the
customer’s  consent  if  the  customer  fails  to  meet  a  margin  call.  Similarly,  securities  pledged  (or  hypothecated)  as  collateral  for  a  loan  may  be  sold  in
foreclosure  if  the  borrower  defaults  on  the  loan.  Because  a  margin  sale  or  foreclosure  sale  may  occur  at  a  time  when  the  pledgor  is  aware  of  material
nonpublic information or otherwise is not permitted to trade in Company Securities, directors, officers and other persons designated by the CEO or CFO
(and  any  other  person  designated  as  subject  to  this  Policy)  are  prohibited  from  holding  Company  Securities  in  a  margin  account  or  otherwise  pledging
Company  Securities  as  collateral  for  a  loan.  Pledges  of  Company  Securities  arising  from  certain  types  of  hedging  transactions  are  governed  by  the
paragraph above captioned “Hedging Transactions”.

4

 
 
 
 
 
 
 
 
 
 
Standing and Limit Orders. Standing and limit orders (except standing and limit orders under approved Rule 10b5-1 Plans, as described below)
create heightened risks for insider trading violations similar to the use of margin accounts. There is no control over the timing of purchases or sales that
result from standing instructions to a broker, and as a result the broker could execute a transaction when a director, officer, or other employee (or any other
person designated as subject to this Policy) is in possession of material nonpublic information. The Company therefore discourages placing standing or
limit orders on Company Securities. If a person subject to this Policy determines that they must use a standing order or limit order, the order should be
limited to short duration and should otherwise comply with the restrictions and procedures outlined below under the heading “Additional Procedures”.

VIII. Transactions Not Subject to the Policy

Transactions Under Company Plans: This Policy does not apply in the case of the following transactions, except as specifically noted.

Stock  Option  Exercises.  This  Policy  does  not  apply  to  the  exercise  of  a  stock  option  acquired  pursuant  to  the  Company’s  stock  option  and
incentive plans, nor to the exercise of a tax withholding right pursuant to which a person has elected to have the Company withhold shares subject to an
option to satisfy tax withholding requirements. This Policy does apply, however, to any sale of stock as part of a broker-assisted cashless exercise of an
option, or any other market sale for the purpose of generating the cash needed to pay the exercise price of an option.

Restricted Stock Awards/RSUs. This Policy does not apply to the vesting of restricted stock or restricted stock units (“RSUs”), nor to the exercise
of a tax withholding right pursuant to which a person has elected to have the Company withhold shares of stock to satisfy tax withholding requirements
upon the vesting of any restricted stock or RSUs. The Policy does not apply to any market sale of shares to cover withholding or related tax obligations
under vesting restricted stock or RSUs.

401(k)  Plan.  This  Policy  does  not  apply  to  purchases  of  Company  Securities  in  any  Company  401(k)  plan  resulting  from  your  periodic
contribution of money to the plan pursuant to your payroll deduction election. This Policy does or can, in the future, apply to certain elections you may
make  under  a  401(k)  plan,  including:  (a)  an  election  to  increase  or  decrease  the  percentage  of  your  periodic  contributions  that  will  be  allocated  to  the
Company stock fund; (b) an election to make an intra-plan transfer of an existing account balance into or out of the Company stock fund; (c) an election to
borrow money against a 401(k) plan account if the loan will result in a liquidation of some or all of your Company stock fund balance; and (d) an election
to pre-pay a plan loan if the pre-payment will result in allocation of loan proceeds to the Company stock fund.

Other Similar Transactions. Any other purchase of Company Securities from the Company or sales of Company Securities to the Company are not

subject to this Policy.

Transactions not involving a Purchase or Sale: Bona fide gifts are not transactions subject to this Policy, unless the person making the gift has reason to
believe that the recipient intends to sell the Company Securities while the director, officer, or other employee (or any other person designated as subject to
this Policy) is aware of material nonpublic information. Further, transactions in mutual funds that are invested in Company Securities are not transactions
subject to this Policy.

IX. Additional Procedures

The  Company  has  established  additional  procedures  to  assist  the  Company  in  the  administration  of  this  Policy,  to  facilitate  compliance  with  laws
prohibiting  insider  trading  while  in  possession  of  material  nonpublic  information,  and  to  avoid  the  appearance  of  any  impropriety.  These  additional
procedures are applicable only to those individuals described below.

5

 
 
 
 
 
 
 
 
 
 
 
 
Pre-Clearance Procedures. When being an insider, any person subject to this Policy, as well as the Family Members and Controlled Entities of
such persons, may not engage in any transaction in Company Securities without first obtaining pre-clearance of the transaction from the CFO. A request for
pre-clearance should be submitted to the CFO in writing at least two business days in advance of the proposed transaction. The CFO is under no obligation
to approve a transaction submitted for pre-clearance and may determine not to permit the transaction. If a person seeks pre-clearance and permission to
engage in the transaction is denied, then he or she should refrain from initiating any transaction in Company Securities and should not inform any other
person of the restriction. If permission to trade is given, the trade must be affected within five business days unless otherwise agreed by the CFO.

When a request for pre-clearance is made, the requestor should carefully consider whether he or she may be aware of any material nonpublic information
about the Company and should describe fully those circumstances to the CFO. The requestor should also indicate whether he or she has affected any non-
exempt “opposite-way” transactions within the past six months and should be prepared to report the proposed transaction on an appropriate Form 4 or Form
5. The requestor should also be prepared to comply with SEC Rule 144 and file Form 144, if necessary, at the time of any sale.

Quarterly  Blackout  Period.  No  person  subject  to  this  Policy  may  buy  or  sell  Company  Securities  during  the  “Quarterly  Blackout  Period,”
beginning two (2) weeks before the last day of each quarter of the Company’s fiscal year and ending on the close of business of the third full trading day
after the public announcement of the Company’s quarterly results. An exercise of a stock option is not prohibited during a Quarterly Blackout Period (but
the sale of the shares acquired on exercise is prohibited). Likewise, purchases pursuant to any Company employee stock purchase plan are not prohibited
(but the subsequent sale of such shares is prohibited, as is the sale of shares held in a 401(k) plan).

Event-Specific Blackout Period. From time to time, an event may occur that is material to the Company and is known by only a few directors,
officers and/or employees. So long as the event remains material and nonpublic, the persons designated by the EC may not trade in Company Securities. In
addition, the Company’s financial results may be sufficiently material in a particular fiscal quarter that, in the judgment of the CEO or CFO, designated
persons should refrain from trading in Company Securities even sooner than the Quarterly Blackout Period described above. In such situations (an “Event-
Specific Blackout Period”), the EC or any other employee designated by them will notify these persons that they may not trade in Company Securities. The
existence of an Event-Specific Blackout Period or extension of a Quarterly Blackout Period will not be announced to the Company as a whole and should
not be communicated to any other person.

Even if you are not designated as a person who may not trade during an Event-Specific Blackout Period, you should not trade while aware of material
nonpublic information. Exceptions will not be granted during an Event-Specific Blackout Period. The existence or non-existence of a blackout period does
not alter the general prohibitions against trading based on material nonpublic information, which are applicable at all times.

X. Rule 10b5-1 Plans

Rule 10b5-1 under the Exchange Act provides a defense from insider trading liability under Rule 10b-5. In order to be eligible to rely on this defense, a
person subject to this Policy must enter into a Rule 10b5-1 plan for transactions in Company Securities that meets certain conditions specified in the rule (a
“Rule 10b5-1 Plan”). If the plan meets the requirements of Rule 10b5-1, Company Securities may be purchased or sold without regard to certain insider
trading restrictions. To comply with the Policy, a Rule 10b5-1 Plan must be acknowledged and authorized by the CEO or CFO and meet the requirements
of Rule 10b5-1. In general, a Rule 10b5-1 Plan must be entered into at a time when the person entering into the plan is not aware of material nonpublic
information. Once the plan is adopted, the person must not exercise any influence over the amount of securities to be traded, the price at which they are to
be traded or the date of the trade. The plan must either specify the amount, pricing and timing of transactions in advance or delegate discretion on these
matters to an independent third party.

Any  Rule  10b5-1  Plan  must  be  submitted  for  approval  ten  days  prior  to  the  entry  into  the  Rule  10b5-1  Plan.  No  further  pre-approval  of  transactions
conducted pursuant to the Rule 10b5-1 Plan will be required.

6

 
 
 
 
 
 
 
 
 
 
XI. Post-Termination Transactions

This Policy continues to apply to transactions in Company Securities even after a person’s termination of service to the Company or its respective affiliates
or  subsidiaries.  If  an  individual  is  in  possession  of  material  nonpublic  information  when  his  or  her  service  terminates,  that  individual  may  not  trade  in
Company Securities until that information has become public or is no longer material.

XII. Consequences of Violations

The purchase or sale of securities while aware of material nonpublic information, or the disclosure of material nonpublic information to others who then
trade in Company Securities, is prohibited by federal and state laws. Insider trading violations are pursued vigorously by the SEC, U.S. Attorneys and state
enforcement authorities as well as the laws and authorities of foreign jurisdictions. Insider trading is a criminal offense, not merely a misdemeanor, and the
punishment for insider trading violations are therefore severe and could include significant fines and even imprisonment. While the regulatory authorities
concentrate  their  efforts  on  the  individuals  who  trade,  or  who  tip  inside  information  to  others  who  trade,  the  US  federal  securities  laws,  as  well  as  the
corresponding laws of other countries, also impose potential liability on companies and other “controlling persons” if they fail to take reasonable steps to
prevent insider trading by company personnel.

In  addition,  an  individual’s  failure  to  comply  with  this  Policy  may  subject  the  individual  to  Company-imposed  sanctions,  including  and  up  to,  without
limitation, removal from one’s position and dismissal for cause, whether or not a person’s failure to comply with the Policy results in a violation of law.
Needless  to  say,  a  violation  of  law,  or  even  an  SEC  investigation  that  does  not  result  in  prosecution,  can  tarnish  a  person’s  reputation  and  irreparably
damage a career.

XIII. Administration of the Policy

The Company’s CEO and CFO, and in such person’s absence, the Company’s Controller or another employee designated by the CEO, shall be responsible
for administration of this Policy. All determinations and interpretations by the CEO and CFO shall be final and not subject to further review.

Any person who has a question about this Policy or its application to any proposed transaction may obtain additional guidance from the CFO. Just drop by
at his office, give him a call on his phone or send him an email to CFO@opgen.com.

XIV. Certification

All  persons  subject  to  this  Policy  must  certify  their  understanding  of,  and  intent  to  comply  with,  this  Policy  by  signing  and  returning  the  respective
certification or (electronic) training record to the respective HR-dept. Certification is necessary upon joining OpGen-group or after material changes were
made to the policy.

OPGEN, INC.
COMPENSATION RECOUPMENT POLICY

Exhibit 97.1

1.  Restatement.  In  the  event  of  any  required  accounting  restatement  of  the  financial  statements  of  OpGen,  Inc.  (the  “Company”)  due  to  the
material noncompliance of the Company with any financial reporting requirement under the applicable U.S. federal securities laws, including any required
accounting restatement to correct an error in previously issued financial statements that is material to the previously issued financial statements, or that
would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period (a “Restatement”),  the
Company will recover reasonably promptly from any person who is or was an “Executive Officer,” as such term is defined in Rule 10D-1 adopted under
the Securities Exchange Act of 1934, as amended (the “Exchange Act”)  and  Rule  5608  of  the  Nasdaq  listing  rules,  of  the  Company  (each,  a  “Covered
Person”) the amount of any “Erroneously Awarded Incentive-Based Compensation” (as defined below). This Policy is effective as of October 2, 2023, the
effective date of Rule 5608 of the Nasdaq listing rules (the “Effective Date”).

2. Amount.  The  amount  of  Incentive-Based  Compensation  (as  defined  below)  that  must  be  recovered  from  a  Covered  Person  pursuant  to  the
immediately preceding paragraph is the amount of “Recoverable Incentive-Based Compensation” (as defined below) received by a Covered Person that
exceeds the amount of Recoverable Incentive-Based Compensation that otherwise would have been received had it been determined based on the restated
amounts,  computed  without  regard  to  any  taxes  paid  (referred  to  as  the  “Erroneously  Awarded  Incentive-Based  Compensation”).  For  Recoverable
Incentive-Based Compensation based on stock price or total shareholder return, where the amount of Erroneously Awarded Incentive-Based Compensation
is not subject to mathematical recalculation directly from the information in a Restatement, the amount must be based on a reasonable estimate of the effect
of the Restatement on the stock price or total shareholder return, as applicable, upon which the Recoverable Incentive-Based Compensation was received,
and the Company must maintain documentation of that reasonable estimate and provide such documentation to the Nasdaq Stock Market LLC (“Nasdaq”).
For the purposes of this Policy, Recoverable Incentive-Based Compensation will be deemed to be received in the fiscal period during which the financial
reporting measure specified in the applicable Incentive-Based Compensation award is attained, even if the payment or grant occurs after the end of that
period.

3. Definitions:

(a)  “Incentive-Based  Compensation”  means  any  compensation  that  is  granted,  earned  or  vested  based  wholly  or  in  part  upon  the
attainment of a “financial reporting measure,” which means a measure that is determined and presented in accordance with Generally Accepted Accounting
Principles which are used in preparing the Company’s financial statements, and any measure that is derived wholly or in part from such measures. Stock
price and total shareholder return are also financial reporting measures for this purpose. For avoidance of doubt, a financial reporting measure need not be
presented within the Company’s financial statements or included in a filing with the Securities and Exchange Commission.

(b) “Recoverable  Incentive-Based  Compensation”  means  all  Incentive-Based  Compensation  received  on  or  after  the  Effective  Date  of
this Policy set forth above by a Covered Person: (i) after beginning service as an executive officer; (ii) who served as an Executive Officer at any time
during  the  performance  period  for  the  Incentive-Based  Compensation;  (iii)  while  the  Company  has  a  class  of  securities  listed  on  a  national  securities
exchange or a national securities association; and (iv) during the three completed fiscal years immediately preceding the date that the Company is required
to  prepare  a  Restatement,  including  any  applicable  transition  period  that  results  from  a  change  in  the  Company’s  fiscal  year  within  or  immediately
following those three completed fiscal years. For this purpose, the Company is deemed to be required to prepare a Restatement on the earlier of: (i) the date
the Board of Directors of the Company (the “Board”), or the Company’s officers authorized to take such action if Board action is not required, concludes,
or reasonably should have concluded, that the Company is required to prepare a Restatement; and (ii) the date a court, regulator or other legally authorized
body  directs  the  Company  to  prepare  a  Restatement.  The  Company’s  obligation  to  recover  Erroneously  Awarded  Incentive-Based  Compensation  is  not
dependent on if or when the restated financial statements are filed with the Securities and Exchange Commission.

 
 
 
 
 
 
 
 
 
4.  Recovery.  The  Company  must  recover  the  Erroneously  Awarded  Incentive-Based  Compensation  from  Covered  Persons  unless  the  Board
determines  that  recovery  is  impracticable  because:  (i)  the  direct  expense  to  a  third  party  to  assist  in  enforcing  this  Policy  would  exceed  the  amount  of
Erroneously Awarded Incentive-Based Compensation; provided that, the Company must make a reasonable attempt to recover the Erroneously Awarded
Incentive-Based Compensation before concluding that recovery is impracticable, document such reasonable attempt to recover the Erroneously Awarded
Incentive-Based Compensation and provide such documentation to Nasdaq; or (ii) recovery would likely cause an otherwise tax-qualified retirement plan,
under which benefits are broadly available to employees of the Company, to fail to meet the applicable requirements of 26 U.S.C. 401(a)(13) or 26 U.S.C.
411(a) and regulations thereunder.

5. No Indemnification. In no event will the Company indemnify any Covered Person for any amounts that are recovered under this Policy. This
Policy  is  in  addition  to  (and  not  in  lieu  of)  any  right  of  repayment,  forfeiture  or  right  of  offset  against  any  employees  that  is  required  pursuant  to  any
statutory repayment requirement (regardless of whether implemented at any time prior to or following the adoption or amendment of this Policy), including
Section 304 of the Sarbanes-Oxley Act of 2002. Any amounts paid to the Company pursuant to Section 304 of the Sarbanes-Oxley Act of 2002 will be
considered in determining any amounts recovered under this Policy.

6. Other Company Rights. The application and enforcement of this Policy does not preclude the Company from taking any other action to enforce
a Covered Person’s obligations to the Company, including termination of employment or institution of legal proceedings. Nothing in this Policy restricts the
Company from seeking recoupment under any other compensation recoupment Policy or any applicable provisions in plans, agreements, awards or other
arrangements that contemplate the recoupment of compensation from a Covered Person. If a Covered Person fails to repay Erroneously Awarded Incentive-
Based Compensation that is owed to the Company under this Policy, the Company must take all appropriate action to recover any Erroneously Awarded
Incentive-Based Compensation from the Covered Person, and the Covered Person will be required to reimburse the Company for all expenses (including
legal expenses) incurred by the Company in recovering the Erroneously Awarded Incentive-Based Compensation.

7.  Binding  Effect.  The  terms  of  this  Policy  will  be  binding  and  enforceable  against  all  Covered  Persons  subject  to  this  Policy  and  their
beneficiaries,  heirs,  executors,  administrators  or  other  legal  representatives.  If  any  provision  of  this  Policy  or  the  application  of  such  provision  to  any
Covered Person is adjudicated to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability will not affect any other
provisions of this Policy, and the invalid, illegal or unenforceable provisions will be deemed amended to the minimum extent necessary to render any such
provision (or the application of such provision) valid, legal or enforceable.

8. Acknowledgement by Employee. Each Covered Person must sign and return to the Company, within 30 calendar days following the later of (i)
the Effective Date of this Policy first set forth above or (ii) the date the individual becomes a Covered Person, the Acknowledgement Form attached hereto
as Exhibit A, pursuant to which the Covered Person agrees to be bound by, and to comply with, the terms and conditions of this Policy.

9. Interpretation. This Policy will be interpreted in a manner that is consistent with Rule 10D-1 under the Exchange Act, Rule 5608 of the Nasdaq
listing rules and any related rules or regulations adopted by the Securities and Exchange Commission or Nasdaq (the “Applicable Rules”) as well as any
other  applicable  law.  To  the  extent  the  Applicable  Rules  require  recovery  of  incentive-based  compensation  in  additional  circumstances  beyond  those
specified above, nothing in this Policy will be deemed to limit or restrict the right or obligation of the Company to recover incentive-based compensation to
the fullest extent required by the Applicable Rules.
