**Prospectus**

**321,207 Shares of Common Stock**

**2,586,207 Series A-1 Warrants to Purchase up to 2,586,207 Shares of Common Stock**

**2,586,207 Series A-2 Warrants to Purchase up to 2,586,207 Shares of Common Stock**

**2,265,000 Pre-Funded Warrants to Purchase up to 2,265,000 Shares of Common Stock**

**7,437,414 Shares of Common Stock Underlying the Common Warrants and Pre-Funded Warrants**

**___________________**

We are offering 321,207 shares of our common stock together with Series A-1 warrants to purchase up to 2,586,207 shares of common stock and Series A-2 warrants to purchase up to 2,586,207 shares of our common stock. The Series A-1 and Series A-2 warrants are collectively referred to herein as the "common warrants". Each share of our common stock, or pre-funded warrant in lieu thereof, is being sold together with a Series A-1 warrant to purchase one share of our common stock and Series A-2 warrant to purchase one share of our common stock. The shares of common stock and common warrants are immediately separable and will be issued separately in this offering, but must be purchased together in this offering. The public offering price for each share of common stock and accompanying warrant is $2.90. Each common warrant will have an exercise price per share of $2.65 and will be immediately exercisable. The Series A-1 warrants will expire on the 5 year anniversary of the original issuance date. The Series A-2 warrants will expire on the 18-month anniversary of the original issuance date.

We are also offering to certain purchasers whose purchase of shares of common stock in this offering would otherwise result in the purchaser, together with its affiliates and certain related parties, beneficially owning more than 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding common stock immediately following the consummation of this offering, the opportunity to purchase, if any such purchaser so chooses, pre-funded warrants, in lieu of shares of common stock that would otherwise result in such purchaser's beneficial ownership exceeding 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding common stock. The public offering price of each pre-funded warrant and accompanying common warrant will be equal to the price at which one share of common stock and accompanying common warrant is sold to the public in this offering, minus $0.01, and the exercise price of each pre-funded warrant will be $0.01 per share. The pre-funded warrants will be immediately exercisable and may be exercised at any time until all of the pre-funded warrants are exercised in full. The pre-funded warrants and common warrants are immediately separable and will be issued separately in this offering, but must be purchased together in this offering. Pursuant to this prospectus, we are also offering the shares of common stock issuable upon exercise of the common warrants and pre-funded warrants.

This offering will terminate on January 20, 2023, unless we decide to terminate the offering (which we may do at any time in our discretion) prior to that date. We will have one closing for all the securities purchased in this offering. The combined public offering price per share (or pre-funded warrant) and common warrant will be fixed for the duration of this offering.

Our common stock is listed on The Nasdaq Capital Market under the symbol "OPGN". On January 10, 2023, the last reported sale price of our common stock on The Nasdaq Capital Market was $2.41 per share. The public offering price per share of common stock and accompanying common warrant and per pre-funded warrant and accompanying common warrant will be determined between us and investors based on market conditions at the time of pricing, and may be at a discount to the then current market price of our common stock. The recent market price used throughout this prospectus may not be indicative of the actual offering price. The actual public offering price may be based upon a number of factors, including our history and our prospects, the industry in which we operate, our past and present operating results, the previous experience of our executive officers and the general condition of the securities markets at the time of this offering. There is no established public trading market for the pre-funded warrants and the common warrants and we do not expect a market to develop. Without an active trading market, the liquidity of the pre-funded warrants and the common warrants will be limited. In addition, we do not intend to list the pre-funded warrants or the common warrants on The Nasdaq Capital Market, any other national securities exchange or any other trading system.

We have engaged H.C. Wainwright & Co., LLC, or the placement agent, to act as our exclusive placement agent in connection with this offering. The placement agent has agreed to use its reasonable best efforts to arrange for the sale of the securities offered by this prospectus. The placement agent is not purchasing or selling any of the securities we are offering and the placement agent is not required to arrange the purchase or sale of any specific number of securities or dollar amount.

**Overview**

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

Our focus is on our combined broad portfolio of products, which include high impact rapid diagnostics and bioinformatics to interpret antimicrobial resistance (AMR) genetic data. We will continue to develop and seek FDA and other regulatory clearances or approvals, as applicable, for additional diagnostic tests. We will continue to offer the FDA-cleared Unyvero LRT and LRT BAL Panels, Acuitas AMR Gene Panel diagnostic test, as well as the Unyvero UTI Panel as a research use only (RUO) products to hospitals, public health departments, clinical laboratories, pharmaceutical companies and contract research organizations (CRO). We are also continuing to commercialize our CE-marked Unyvero Panels in Europe and other global markets through distributors.

The Company currently expects to focus on the following products for lower respiratory infection, urinary tract infection and invasive joint infection:

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Following
 registration of the Unyvero instrument system as an in vitro diagnostics (IVD) platform for
 the Chinese market in early 2021, we are supporting our strategic partner Beijing Clear Biotech
 (BCB) in pursuing execution of a supplemental clinical trial with the Unyvero HPN test for
 hospitalized pneumonia, or HPN. As requested by the Chinese regulatory authority National
 Medical Products Administration (NMPA), this study is geared towards generating additional
 data in China that will complement a larger data set with data from abroad compiled from
 other clinical and analytical studies performed in the past. As a result of the Chinese regulatory
 authority's recent adoption of a new electronic submission regime, we plan to prepare a new
 submission BCB and their regulatory advisors for our pneumonia cartridge filing and currently
 expect to complete the process within 24 to 30 months.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The
 Unyvero Urinary Tract Infection, or UTI, test, which is CE-IVD marked in Europe, is currently
 being made available to laboratories in the United States as an RUO kit. The test detects
 a broad range of pathogens as well as antimicrobial resistance markers directly from native
 urine specimens. We initiated a prospective multi-center clinical trial for the Unyvero UTI
 in the United States in the third quarter of 2021, presented positive data from an interim
 analysis in the first quarter of 2022, and completed enrollment at the end of the third quarter
 of 2022.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The
 Unyvero Invasive Joint Infection, or IJI, test, which is a test specifically being developed
 for the U.S. market on the Unyvero A30 platform, has also been selected for analytical and
 clinical performance evaluation including clinical trials towards a future submission to
 the FDA. We anticipate such clinical trial not to commence before the second quarter of 2023.
 Microbial diagnosis of IJI is difficult because of challenges in sample collection, usually
 at surgery, and patients being on prior antibiotic therapy which minimizes the chances of
 recovering viable bacteria. We believe that the Unyvero IJI test could be useful in identifying
 pathogens as well as their AMR markers to help guide optimal antibiotic treatment for these
 patients.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· On
 September 30, 2021, we received clearance from the FDA for our Acuitas AMR Gene Panel for
 bacterial isolates. The Acuitas AMR Gene Panel detects 28 genetic AMR markers in isolated
 bacterial colonies from 26 different pathogens. We believe the panel provides clinicians
 with a valuable diagnostic tool that informs about potential AMR patterns early and supports
 appropriate antibiotic treatment decisions in this indication. We have begun commercializing
 the Acuitas AMR Gene Panel for isolates to customers in the United States and have successfully
 signed the first two commercial contracts with customers and completed system installation
 and user training for such customers.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· We
 recently entered into a research and development collaboration with FIND, the global alliance
 for diagnostics, which will fund the development of the A30 *RQ* platform for use in
 low and middle income countries (LMICs). The initial project focuses on a feasibility study
 for the rapid detection of AMR from blood culture. The feasibility phase of this research
 and development project is set to conclude by the end of the first quarter of 2023 and funded
 by FIND with €700 thousand.

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· We
 commenced offering validated high quality sequencing and analysis services with rapid turnaround
 times for key applications in microbiology. The unique and differentiated offering for rapid
 and comprehensive genetic characterization of bacterial isolates and interpretive services
 include whole genome sequencing, taxonomic identification and typing, detection of plasmids,
 and other mobile elements, AMR and virulence markers. Furthermore, the RUO services provided
 by OpGen's laboratory in Rockville, MD, will provide prediction of phenotypic antibiotic
 susceptibility based on our ARESdb database as well as specialized software for bacterial
 outbreak analysis via our AREScloud web application.

**Recent Developments**

**Nasdaq Notice**

On February 28, 2022, we received a notice from The Nasdaq Stock Market LLC, or Nasdaq, notifying us that, based upon the closing bid price of our common stock, for the 30 consecutive business days prior to the notice, the Company no longer met the requirement to maintain a minimum closing bid price of $1.00 per share, as set forth in Nasdaq Listing Rule 5550(a)(2). The Company was originally granted 180 calendar days, or until August 29, 2022, to regain compliance with the minimum bid price rule. On August 30, 2022, Nasdaq notified the Company that it had been granted an additional 180-calendar day compliance period, or until February 27, 2023, to regain compliance with the Minimum Bid Price Rule. In connection with the grant of such additional compliance period, the Company provided notice to Nasdaq that it intended to cure the bid price deficiency by effecting a reverse stock split, if necessary, prior to the end of the compliance period. While we have until February 27, 2023 to regain such compliance, we do not believe we will be able to do so without implementing a reverse stock split. In order to regain compliance, the Company accordingly called a special meeting of stockholders that was held on November 30, 2022 at which our stockholders voted on and approved a proposal to amend our Amended and Restated Certificate of Incorporation, as amended, or, the Charter, to authorize a reverse stock split of the issued and outstanding shares of our common stock, at a ratio within a range of not less than one-for-five (1:5) and not more than one-for-twenty (1:20), such ratio and the implementation and timing of such reverse stock split to be determined in the discretion of our Board of Directors. Our Board of Directors determined to effect the reverse stock split at a ratio of one-for-twenty (1:20). On January 4, 2023, we filed a Certificate of Amendment, or the Amendment, to our Charter to effect the reverse stock split, or the 2023 Reverse Stock Split, which became effective on January 5, 2023.

If we are not in compliance with the minimum bid price requirement by February 27, 2023, we can appeal Nasdaq's determination to a hearings panel in order to present a plan to regain compliance. There can be no assurances however that we will be granted any relief or additional time to regain compliance with the minimum bid price requirement and do not believe that any additional grace period will allow the Company to comply with the minimum closing bid price requirement unless a reverse stock split is not approved. Although we expect that the 2023 Reverse Stock Split will result in a sustained increase in the market price of our common stock, the 2023 Reverse Stock Split may not result in a permanent increase in the market price of our common stock, which is dependent on many factors, including general economic, market and industry conditions and other factors detailed from time to time in the reports we file with the SEC.

*Reverse Stock Split*

On November 30, 2022, at a special meeting of stockholders, or the Special Meeting, our stockholders approved an amendment to our Charter to effect a reverse stock split of our common stock, at a ratio of not less than one-for-five (1:5) and not more than one-for-twenty (1:20), with the final ratio and timing of such reverse stock split to be determined in the discretion of our Board of Directors. Our Board of Directors determined to effect the 2023 Reverse Stock Split at a ratio of one-for-twenty. On January 4, 2023, we filed the Amendment to effect the 2023 Reverse Stock Split, which became effective on January 5, 2023. All of the Company's historic share numbers and share prices in this prospectus have been adjusted to reflect the 2023 Reverse Stock Split.

In implementing the 2023 Reverse Stock Split, the number of shares of our common stock held by each stockholder was reduced by dividing the number of shares held immediately before the 2023 Reverse Stock Split by twenty and then rounding down to the nearest whole share. We are paying cash to each stockholder in lieu of issuing any fractional shares. The 2023 Reverse Stock Split did not affect any stockholder's percentage ownership interest in our Company or proportionate voting power, except to the extent that interests in fractional shares were paid in cash.

In addition, we have adjusted all outstanding shares of any restricted stock units, stock options and warrants entitling the holders to purchase shares of our common stock as a result of the 2023 Reverse Stock Split, as required by the terms of these securities. In particular, we have reduced the conversion ratio for each security, and increased the exercise price in accordance with the terms of each security based on 2023 Reverse Stock Split ratio (i.e., the number of shares issuable under such securities has been divided by twenty, and the exercise price per share has been multiplied by twenty). Also, we proportionately reduced the number of shares reserved for issuance under our existing 2015 Equity Incentive Plan, or the 2015 Plan, based on the 2023 Reverse Stock Split ratio. The 2023 Reverse Stock Split did not otherwise affect any of the rights currently accruing to holders of our common stock, or options or warrants exercisable for our common stock.

The following table presents selected share information reflecting the 2023 Reverse Stock Split for the years ended December 31, 2021 and 2020:

---

| | | |
|:---|:---|:---|
|  | Year Ended December 31, | Year Ended December 31, |
|  | 2021 | 2020 |
| Shares Outstanding - pre-split | 46450250 | 25085534 |
| Shares Outstanding - post-split | 2322512 | 1254276 |
| Basic and diluted net loss per share attributable to common stockholders - pre-split | (1.14) | (1.66) |
| Basic and diluted net loss per share attributable to common stockholders - post-split | (22.80) | (33.20) |

*Going Concern*

Our management has concluded that substantial doubt exists about our ability to continue as a going concern for one year from the date of this prospectus. We do not expect that the net proceeds from this offering will be sufficient to allow us to continue as a going concern for one year from the date of this prospectus. With the $6.8 million of net proceeds from this offering, we believe that the net proceeds from this offering, together with our existing cash and cash equivalents, will meet our capital needs into June 2023. If we raise an additional $13.0 million in net proceeds through the sale of securities or otherwise throughout 2023, we believe that we will then meet our capital needs through the end of January 2024.

**<u>Risks Related to this Offering and Our Securities</u>**

***We need to raise capital in this offering to support our operations. If we are unable to raise capital in this offering, our financial position will be materially adversely impacted.***

We have incurred substantial losses since our inception, and we expect to continue to incur additional losses for the next several years. For the three and nine months ended September 30, 2022, we had net losses of $14.1 million and $26.7 million, respectively. From our inception through September 30, 2022, we had an accumulated deficit of $262.3 million. We believe that current cash on hand, prior to the receipt of any proceeds from this offering, is not sufficient to fund operations beyond the first quarter of 2023. With the $6.8 million of net proceeds from this offering, we believe that the net proceeds from this offering, together with our existing cash and cash equivalents, will meet our capital needs into June 2023. If we raise an additional $13.0 million in net proceeds through the sale of securities or otherwise throughout 2023, we believe that we will then meet our capital needs through the end of January 2024. In addition, the report of our independent registered public accounting firm on our financial statements for the years ended December 31, 2021 and 2020 contains explanatory language that substantial doubt exists about our ability to continue as a going concern. If we do not have access to sufficient cash and liquidity to finance our business operations as currently contemplated, we would be compelled to reduce general and administrative expenses and delay research and development projects, including the purchase of scientific equipment and supplies, until we are able to obtain sufficient financing. We have no additional committed sources of capital and may find it difficult to raise money on terms favorable to us or at all. The failure to obtain sufficient capital to support our operations would have a material adverse effect on our business, financial condition and results of operations. If such sufficient financing is not received timely, we would then need to pursue a plan to license or sell assets, seek to be acquired by another entity, cease operations and/or seek bankruptcy protection.

***We received deficiency notices from the Nasdaq Capital Market. If we are unable to cure these deficiencies and meet the Nasdaq continued listing requirements, we could be delisted from the Nasdaq Capital Market, which would negatively impact the trading of our common stock.***

On February 28, 2022, we received a notice from The Nasdaq Stock Market LLC, or Nasdaq, notifying us that, based upon the closing bid price of our common stock, for the 30 consecutive business days prior to the notice, the Company no longer met the requirement to maintain a minimum closing bid price of $1.00 per share, as set forth in Nasdaq Listing Rule 5550(a)(2). The Company was originally granted 180 calendar days, or until August 29, 2022, to regain compliance with the minimum bid price rule. On August 30, 2022, Nasdaq notified the Company that it had been granted an additional 180-calendar day compliance period, or until February 27, 2023, to regain compliance with the Minimum Bid Price Rule. In connection with the grant of such additional compliance period, the Company provided notice to Nasdaq that it intended to cure the bid price deficiency by effecting a reverse stock split, if necessary, prior to the end of the compliance period.

In order to regain compliance, the Company accordingly called and held a special meeting of stockholders on November 30, 2022 at which our stockholders voted on and approved a proposal to amend our Charter to authorize a reverse stock split of the issued and outstanding shares of our common stock, at a ratio within a range of not less than one-for-five (1:5) and not more than one-for-twenty (1:20), such ratio and the implementation and timing of such reverse stock split to be determined in the discretion of our Board of Directors. Following receipt of stockholder approval, on January 4, 2023, we filed the Amendment to our Charter to effect the 2023 Reverse Stock Split at a ratio of 1-to-20 in order to regain compliance with the Nasdaq Minimum Bid Price Rule. Although we expect that the 2023 Reverse Stock Split will result in a sustained increase in the market price of our common stock, the 2023 Reverse Stock Split may not result in a permanent increase in the market price of our common stock, which is dependent on many factors, including general economic, market and industry conditions and other factors detailed from time to time in the reports we file with the SEC. As a result, there can be no assurance that the market price per share of our common stock after the 2023 Reverse Stock Split will remain above the Nasdaq Minimum Bid Price Rule requirement. If the market price per share of our common stock following the 2023 Reverse Stock Split decreases below Nasdaq's Minimum Bid Price Rule requirements, we could again be subject to further delisting procedures by Nasdaq.

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

Delisting from Nasdaq could adversely affect our ability to raise additional financing through public or private sales of equity securities, would significantly affect the ability of investors to trade our securities and would negatively affect the value and liquidity of our common stock. Delisting could also have other negative results, including the potential loss of confidence by employees, the loss of institutional investor interest and fewer business development opportunities.

***Even if the 2023 Reverse Stock Split achieves the requisite increase in the market price of our common stock, we cannot assure you that we will be able to continue to comply with other continued listing standards of the Nasdaq Capital Market.***

Even if the 2023 Reverse Stock Split achieves the requisite increase in the market price of our common stock to be in compliance with the Minimum Bid Price Rule of the Nasdaq Capital Market, there can be no assurance that the market price of our common stock following the 2023 Reverse Stock Split will remain at the level required for continuing compliance with that requirement. It is not uncommon for the market price of a company's common stock to decline in the period following a reverse stock split. If the market price of our common stock declines following the effectuation of the 2023 Reverse Stock Split, the percentage decline may be greater than would occur in the absence of a reverse stock split. In any event, other factors unrelated to the number of shares of our common stock outstanding, such as negative financial or operational results, could adversely affect the market price of our common stock and jeopardize our ability to meet or maintain compliance with Nasdaq's Minimum Bid Price Rule requirements.

The Nasdaq Capital Market requires that the trading price of its listed stocks remain above one dollar in order for the stock to remain listed. If our stock once again trades below such threshold for more than 30 consecutive trading days, then it is subject to delisting from the Nasdaq Capital Market. In addition, to maintain a listing on Nasdaq, we must satisfy minimum financial and other continued listing requirements and standards, including those regarding director independence and independent committee requirements, minimum stockholders' equity, and certain corporate governance requirements. 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. Although we expect that the 2023 Reverse Stock Split will result in a sustained increase in the market price of our common stock, we can provide no assurance that the 2023 Reverse Stock Split would enable us to regain or remain in compliance, stabilize the market price or improve the liquidity of our common stock, prevent our common stock from dropping below the Nasdaq Minimum Bid Price Rule requirements in the future, or prevent future non-compliance with the listing requirements.

***The 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 2023 Reverse Stock Split given the reduced number of shares that will be outstanding following the 2023 Reverse Stock Split, especially if the market price of our common stock does not increase as a result of the 2023 Reverse Stock Split. In addition, the 2023 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.

***Following the 2023 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.***

Although we believe that a higher market price of our common stock may help generate greater or broader investor interest, there can be no assurance that the 2023 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.

***Purchasers who purchase our securities in this offering pursuant to a securities purchase agreement may have rights not available to purchasers that purchase without the benefit of a securities purchase agreement.***

In addition to rights and remedies available to all purchasers in this offering under federal securities and state law, the purchasers that enter into a securities purchase agreement will also be able to bring claims of breach of contract against us. The ability to pursue a claim for breach of contract provides those investors with the means to enforce the covenants uniquely available to them under the securities purchase agreement including: (i) timely delivery of shares; (ii) agreement to not enter into variable rate financings for one year from closing, subject to certain exceptions; (iii) agreement to not enter into any financings for 60 days from closing; and (iv) indemnification for breach of contract.

***This is a best efforts offering, no minimum amount of securities is required to be sold, and we may not raise the amount of capital we believe is required for our business plans, including our near-term business plans.***

The placement agent has agreed to use its reasonable best efforts to solicit offers to purchase the securities in this offering. The placement agent has no obligation to buy any of the securities from us or to arrange for the purchase or sale of any specific number or dollar amount of the securities. There is no required minimum number of securities that must be sold as a condition to completion of this offering. Because there is no minimum offering amount required as a condition to the closing of this offering, the actual offering amount, placement agent fees and proceeds to us are not presently determinable and may be substantially less than the maximum amounts set forth herein. We may sell fewer than all of the securities offered hereby, which may significantly reduce the amount of proceeds received by us, and investors in this offering will not receive a refund in the event that we do not sell an amount of securities sufficient to support our continued operations, including our near-term continued operations. Thus, we may not raise the amount of capital we believe is required for our operations in the short-term and may need to raise additional funds to complete such short-term operations. Such additional fundraises may not be available or available on terms acceptable to us.

***Management will have broad discretion as to the use of the net proceeds from this offering, and we may not use the proceeds effectively.***

Our management will have broad discretion as to the application of the net proceeds and could use them for purposes other than those contemplated at the time of this offering. Our stockholders may not agree with the manner in which our management chooses to allocate and spend the net proceeds. Moreover, our management may use the net proceeds for corporate purposes that may not increase our results of operations or the market value of our common stock. Our failure to apply these funds effectively could have a material adverse effect on our business, delay the development and approval of our products and cause the price of our common stock to decline.

***If you purchase common stock sold in this offering, you will experience immediate dilution as a result of this offering.***

Because the price per share of our common stock being offered may be higher than the net tangible book value per share of our common stock, you will experience dilution to the extent of the difference between the offering price per share of common stock you pay in this offering and the net tangible book value per share of our common stock immediately after this offering. Our net tangible book value as of September 30, 2022, was approximately $1.9 million, or $0.80 per share of common stock. Net tangible book value per share is equal to our total tangible assets minus total liabilities, all divided by the number of shares of common stock outstanding. See the section titled "Dilution" for a more detailed discussion of the dilution you will incur if you purchase shares in this offering.

**If you purchase our securities in this offering you may experience future dilution as a result of future equity offerings or other equity issuances.**

In order to raise additional capital, we believe that we will offer and issue additional shares of our common stock or other securities convertible into or exchangeable for our common stock in the future. We cannot assure you that we will be able to sell shares or other securities in any other offering at a price per share that is equal to or greater than the price per share paid by investors in this offering, and investors purchasing other securities in the future could have rights superior to existing stockholders. The price per share at which we sell additional shares of our common stock or other securities convertible into or exchangeable for our common stock in future transactions may be higher or lower than the price per share in this offering.

In addition, we have a significant number of stock options, restricted stock units and warrants outstanding. To the extent that outstanding stock options or warrants have been or may be exercised or other shares issued, you may experience further dilution. Further, we may choose to raise additional capital due to market conditions or strategic considerations even if we believe we have sufficient funds for our current or future operating plans.

***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 2022, the market price of our Common Stock fluctuated from a high of $22.20 per share to a low of $2.40 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· our
 ability to grow our revenue and customer base;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the
 announcement or the market introduction of new products or product enhancements by us or
 our competitors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the
 trading volume of our common stock;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· developments
 concerning regulatory oversight and approvals;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· variations
 in our and our competitors' results of operations;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· successes
 or challenges in our collaborative arrangements or alternative funding sources;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· developments
 in the health care and life science industries;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the
 results of product liability or intellectual property lawsuits;

9 <br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· 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 and Russia's
 war on Ukraine;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the
 continued impact of the COVID-19 pandemic on our business and operations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· future
 issuances of common stock or other securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the
 addition or departure of key personnel;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· 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.

***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 asked 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 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 January 3, 2023, we had outstanding warrants to acquire 1,291,209 shares of our common stock, and stock options to purchase 107,652 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. For example, our loan agreement with the European Investment Bank (EIB) restricts our ability to declare or pay dividends. 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.

10 <br>

**There is no public market for the common warrants or pre-funded warrants to purchase shares of our common stock being offered by us in this offering.**

There is no established public trading market for the common warrants or pre-funded warrants to purchase shares of our common stock that are being offered as part of this offering, and we do not expect a market to develop. In addition, we do not intend to apply to list the common warrants or pre-funded warrants on any national securities exchange or other nationally recognized trading system, including The Nasdaq Capital Market. Without an active market, the liquidity of the common warrants and pre-funded warrants will be limited.

***<u>Risks Related to Our Business</u>***

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

We have incurred substantial losses since our inception, and we expect to continue to incur additional losses for the next several years. For the years ended December 31, 2021 and 2020, we had net losses of $34.8 million and $26.2 million, respectively. From our inception through September 30, 2022, we had an accumulated deficit of $262.3 million. The reports of our independent registered public accounting firm on our financial statements for the years ended December 31, 2021 and 2020 each contain explanatory language that substantial doubt exists about our ability to continue as a going concern. We completed a number of financings in 2021 and 2022, including an at-the-market public offering which commenced in June 2022 (the "ATM Offering") and a registered direct financing in October 2022. The net proceeds from such financings were approximately $52.0 million. We cannot assure you that we can continue to raise the capital necessary to fund our business.

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

**We may not realize the growth and success that we expected from the combination of the OpGen and Curetis businesses.**

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

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

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

11 <br>

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

As of December 31, 2021, we had approximately $202.0 million of net operating loss, or NOL, carryforwards for U.S. federal tax purposes. Under U.S. federal income tax law, we generally can use our NOL carryforwards (and certain tax credits) to offset ordinary taxable income, thereby reducing our U.S. federal income tax liability, for up to 20 years from the year in which the losses were generated, after which time they will expire. State NOL carryforwards (and certain tax credits) generally may be used to offset future state taxable income for 20 years from the year in which the losses are generated, depending on the state, after which time they will expire. The rate at which we can utilize our NOL carryforwards is limited (which could result in NOL carryforwards expiring prior to their use) each time we experience an "ownership change," as determined under Section 382 of the Internal Revenue Code. A Section 382 ownership change generally occurs if a shareholder or a group of shareholders who are deemed to own at least 5% of our common stock increase their ownership by more than 50 percentage points over their lowest ownership percentage within a rolling three-year period. If an ownership change occurs, Section 382 generally would impose an annual limit on the amount of post-ownership change taxable income that may be offset with pre-ownership change NOL carryforwards equal to the product of the total value of our outstanding equity immediately prior to the ownership change (reduced by certain items specified in Section 382) and the U.S. federal long-term tax-exempt interest rate in effect at the time of the ownership change. A number of special and complex rules apply in calculating this Section 382 limitation. While the complexity of Section 382 makes it difficult to determine whether and when an ownership change has occurred, and if a portion of our NOLs is subject to an annual limitation under Section 382, we believe that an additional ownership change may have occurred upon the consummation of the transaction with Curetis. In addition, our ability to use our NOL carryforwards will be limited to the extent we fail to generate enough taxable income in the future before they expire. Existing and future Section 382 limitations and our inability to generate enough taxable income in the future could result in a substantial portion of our NOL carryforwards expiring before they are used. In addition, under the 2017 Tax Cut and Jobs Act, effective for losses arising in taxable years beginning after December 31, 2017, the deduction for NOLs is limited to 80% of taxable income, NOLs can no longer be carried back, and NOLs can be carried forward indefinitely.

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· our
 ability to convince the medical community of the clinical utility of our products and services
 and their potential advantages over existing tests, including our NGS-based isolate sequencing
 services offering, despite the lack of reimbursement for such services;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· our
 ability to further grow our microbial isolate and antibiotic resistance genes knowledgebases
 and bioinformatics offerings;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the ability of hospitals
 and labs to pay for our products and services.

12 <br>

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

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

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

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

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

***We may enter into agreements with U.S. or other international government agencies or non-government organizations (NGO), which could be subject to uncertain future funding.***

The presence of MDROs and the need for antibiotic stewardship activities have prompted state, federal and international government agencies to develop programs to combat the effects of MDROs. From 2018 through September 30, 2021, we were party to a collaboration, called the New York State Infectious Disease Digital Health Initiative, with the New York State DOH and ILÚM (now IDC) to develop a research program to detect, track, and manage antimicrobial-resistant infections at healthcare institutions in New York State. In September 2022, we entered into a research and development collaboration with FIND, an NGO focused on innovative new diagnostics, for the potential use of the Unyvero A30 platform in low and middle income countries (LMICs).

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

13 <br>

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

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

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

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

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

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

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

14 <br>

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· collaborators
 may not perform their obligations as expected;

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

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

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

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

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

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

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

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

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

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

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

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

15 <br>

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

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

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

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

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

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

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

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

16 <br>

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

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

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

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

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

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

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

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

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

17 <br>

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

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

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

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

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

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

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

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

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

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

18 <br>

**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 of the type 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 perform tests, provide test results, bill facilities or patients, process claims and appeals, provide customer assistance services, conduct research and development activities, collect, process and prepare Company financial information, provide information about our current and future solutions and other patient and clinician education and outreach efforts through our website, and manage the administrative aspects of our business and damage our reputation, any of which could adversely affect our business. Any such breach could also result in the compromise of our trade secrets and other proprietary information, which could adversely affect our competitive position.

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

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

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

In addition, in the United States, there are state and federal laws relating to data privacy and security. As we expand our operations, these laws which vary from jurisdiction to jurisdiction, may increase our compliance costs and potential liability. In addition to California, Virginia and Maine, other states are beginning to propose similar laws, which may be the beginning of a trend toward more stringent privacy legislation in the United States that could increase our potential liability and adversely affect our business, results of operations and financial condition.

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

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· failure of the tests at
 the research or development stage;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· lack of clinical validation
 data to support the effectiveness of the tests;

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· lack of commercial acceptance
 by inpatient healthcare facilities and commercial partners.

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

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

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

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

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

***If our acquired in-process research and development costs or finite-lived tangible and intangible assets or any future goodwill become impaired in the future, we may be required to record non-cash charges to earnings, which could be material and could reduce stockholders' equity or otherwise adversely affect the Company's financial condition.***

We review long-lived assets, including property and equipment and identifiable amortizing intangible assets, for impairment whenever changes in circumstances or events may indicate that the carrying amounts are not recoverable. If the fair value is less than the carrying amount of the asset, an impairment is recognized for the difference. Factors which may cause an impairment of long-lived assets include significant changes in the manner of use of these assets, negative industry or market trends, a significant underperformance relative to historical or projected future operating results, extended period of idleness or a likely sale or disposal of the asset before the end of its estimated useful life. For example, in 2021, the Company had determined that the right-of-use asset associated with the Company's San Diego, California office lease may not be recoverable, and, as a result, the Company recorded an impairment charge of $171 thousand during the six months ended June 30, 2021. There can be no assurance that our other long-lived assets and intangible assets will not be further impaired. If our property and equipment and identifiable amortizing intangible assets are determined to be impaired in the future, we may be required to record non-cash charges to earnings during the period in which the impairment is determined, which could be material and have an adverse effect on our financial position and results of operations.

21 <br>

In addition, we review and test goodwill for impairment at least annually and whenever changes in circumstances indicate that the carrying value of the goodwill may not be recoverable. The impairment test for goodwill consists of comparing the fair value of the reporting unit and acquired in-process research and development projects (IPR&D), which is estimated using both the income and market approach, to its carrying value. The process of impairment testing for our goodwill involves a number of judgments and estimates made by management including future cash flows, revenue growth rates, profitability assumptions, terminal growth rates and discount rates with regards to our reporting unit. Our internally generated long-range plan includes assumptions regarding pricing and operating forecasts for our products and technologies. For instance, based on the goodwill impairment assessment performed during the quarter ended September 30, 2022, and primarily due to recent changes in the Company's stock price and market capitalization, it was determined that goodwill was impaired. As a result, the Company recorded a one-time non-cash goodwill impairment charge in the full amount of $6,975,520 for the three and nine months ended September 30, 2022. Accordingly, if the judgments and estimates used in such analyses are not realized or are affected by external factors, our actual results may not be consistent with such judgments and estimates, and we may be required to record further impairment of the Company's assets in the future, which could be material, could reduce stockholders' equity and have an adverse effect on our financial position and results of operations.

***<u>Risks Related to Our Public Company Status</u>***

**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.

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

22 <br>

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

We believe that we currently have a large base of individual stockholders instead of institutional investors. Procuring the vote of such stockholders in connection with certain corporate transactions and matters is difficult, time consuming and expensive. For example, in connection with the Company's 2021 and 2022 Annual Meetings of stockholders, despite extensive efforts by the Company, we were unable to receive votes from a sufficient portion of our outstanding shares of common stock required to approve certain proposals submitted at such meeting.

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

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

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

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

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

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

***<u>Risks Related to Regulation of Our Business</u>***

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

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

23 <br>

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

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

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

We have limited experience in complying with the rules and regulations of the FDA and foreign regulatory authorities. The rapid diagnostic products regulated as medical devices, and the manufacturing processes, reporting requirements, post-approval clinical data and promotional activities for such products, are subject to continued regulatory review, oversight and periodic inspections by the FDA and other domestic and foreign regulatory bodies. In particular, we and our suppliers are required to comply with FDA's Quality System Regulations (QSR) for the manufacture, labeling, distribution and promotion of products and other regulations which cover the methods and documentation of the design, testing, production, control, quality assurance, labeling, packaging, storage and shipping of any product for which we obtain clearance or approval, and with ISO regulations. The FDA enforces the QSR and similarly, other regulatory bodies with similar regulations enforce those regulations through periodic inspections. The failure by us or one of our suppliers to comply with applicable statutes and regulations administered by the FDA and other regulatory bodies, or the failure to timely and adequately respond to any adverse inspectional observations or product safety issues, could result in, among other things, any of the following enforcement actions against us: (1) untitled letters, Form 483 observations, warning letters, fines, injunctions, consent decrees and civil penalties; (2) unanticipated expenditures to address or defend such actions; (3) customer notifications for repair, replacement and refunds; (4) recall, detention or seizure of our products; (5) operating restrictions or partial suspension or total shutdown of production; (6) refusing or delaying our requests for De Novo classification, 510(k) clearance or premarket approval (PMA) of new products or modified products; (7) operating restrictions; (8) withdrawing granted De Novo classifications, 510(k) clearances or PMAs that have already been granted; (9) refusal to grant export approval for our products; or (10) criminal prosecution.

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

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

24 <br>

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

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

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

**Modifications to our marketed products may require new 510(k) clearances, De Novo classifications or PMAs or, in the future, new CE-IVD markings that comply with the new EU Regulation on In Vitro Diagnostic Medical Devices (IVDR), or may require us to cease marketing or recall the modified products until clearances or approvals are obtained.**

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

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

25 <br>

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

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

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

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

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

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

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

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

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

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

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

26 <br>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· export or import restrictions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· various reimbursement
 and insurance regimes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· laws and business practices
 favoring local companies;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· political and economic
 instability;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· foreign exchange controls;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· difficulties and costs
 of staffing and managing foreign operations; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· difficulties protecting
 or procuring intellectual property rights.

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

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

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

**<u>Risks Related to Compliance with Healthcare and Regulations</u>**

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

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

27 <br>

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

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

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

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

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

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

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

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

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

28 <br>

**<u>Risks Related to Our Intellectual Property</u>**

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

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

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

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

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

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

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

29 <br>

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

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

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

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

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

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

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

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

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

30 <br>

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

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

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

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

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

**<u>General Risk Factors</u>**

**The COVID-19 pandemic has and other similar pandemic events may adversely impact our business, financial condition and results of operations.**

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

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

For ongoing and/or planned future trials, we have seen an increasing number of clinical trial sites imposing restrictions on patient visits to limit risks of possible COVID-19 exposure, and we may experience issues with participant compliance with clinical trial protocols as a result of quarantines, travel restrictions and interruptions to healthcare services. The current pressures on medical systems and the prioritization of healthcare resources toward the COVID-19 pandemic have also resulted in interruptions in data collection and submissions for certain clinical trials and delayed starts for certain planned studies such as for example the supplemental clinical study in China. Further, health regulatory agencies globally may also experience disruptions in their operations as a result of the COVID-19 pandemic. The FDA and comparable foreign regulatory agencies have had and may continue to have slower response times or be under-resourced, which could significantly delay the FDA's ability to timely review and process any submissions we or our partners have filed or may file. The FDA in 2021 notified us that the agency would continue prioritizing emergency use authorization requests for diagnostic products intended to address the COVID-19 pandemic during 2021. Due to delays from such prioritization, we only received a clearance decision on our Acuitas AMR Gene Panel on September 30, 2021, which was originally targeted for a decision by mid-2020 and we did not receive responses to our most recent requests for pre-submission meetings.

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

At this point in time, there remains significant uncertainty relating to the potential effect of the coronavirus on our business and results of operations. As coronavirus and its mutations become endemic, it could have a continued negative impact on our ability to operate our business, financial condition and results of operations as well as virtual marketing, sales and customer service interactions not being as effective as in-person interactions. While several vaccines have been approved for use, and with vaccination programs successfully implemented in many countries, the limited acceptance of vaccination by many individuals in the United States as well as in Europe and globally, and potential failure to be effective for all known mutations of the SARS-CoV-2 virus still makes it hard to predict if and when the pandemic will subside and remain endemic.

32 <br>

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

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

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

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

On April 1, 2020, we assumed the indebtedness of Curetis GmbH. As of September 30, 2022, we owed indebtedness of $14.2 million (€14.5 million) of principal (including deferred interest of $1.7 million (€1.8 million)) under a loan provided by the EIB with remaining maturities in June 2023 and June 2024. In particular, of the approximately $15 million of such indebtedness that was due to the EIB in April 2022, we had paid approximately $5 million and have agreed to amortize the remaining amount over a 12-month period in monthly installments of approximately $700 thousand each. While we continue evaluating options to restructure the remaining indebtedness, we may not be able to do so, and in such event, OpGen may not be able to generate sufficient cash to service all of its indebtedness and may be forced to take other actions to satisfy its obligations under indebtedness that may not be successful. The inability in the future to repay such indebtedness when due would have a material adverse effect on us.

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

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

33 <br>

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

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

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

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

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

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

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the difficulty in combining
 our financial operations and reporting;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the potential disruption
 of the ongoing businesses and distraction of our management;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· risks related to international
 operations;

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the potential inability
 to manage an increased number of locations and employees.

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

34 <br>

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

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

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

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

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

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

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

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

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

***The Company's Charter provides that the Court of Chancery of the State of Delaware will be the sole and exclusive forum for substantially all disputes between the Company and its stockholders, which could limit its stockholders' ability to obtain a favorable judicial forum for disputes with the Company or its directors, officers or other employees.***

The Company's Charter provides that, unless the Company consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware will be the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of the Company, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of the Company or its stockholders, (iii) any action asserting a claim arising pursuant to any provision of the DGCL or the Company's Certificate of Incorporation or Bylaws, or (iv) any action asserting a claim governed by the internal affairs doctrine. This exclusive forum provision is intended to apply to claims arising under Delaware state law and would not apply to claims brought pursuant to the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, or any other claim for which the federal courts have exclusive jurisdiction. The exclusive forum provision in the Company's Charter will not relieve the Company of its duties to comply with the federal securities laws and the rules and regulations thereunder, and stockholders of the Company will not be deemed to have waived the Company's compliance with these laws, rules and regulations.

This exclusive forum provision may limit a stockholder's ability to bring a claim in a judicial forum of its choosing for disputes with the Company or its directors, officers or other employees, which may discourage lawsuits against the Company and its directors, officers and other employees. In addition, stockholders who do bring a claim in the Court of Chancery of the State of Delaware could face additional litigation costs in pursuing any such claim, particularly if they do not reside in or near Delaware. The Court of Chancery of the State of Delaware may also reach different judgments or results than would other courts, including courts where a stockholder would otherwise choose to bring the action, and such judgments or results may be more favorable to the Company than to its stockholders. However, the enforceability of similar exclusive forum provisions in other companies' certificates of incorporation has been challenged in legal proceedings, and it is possible that a court could find this type of provision to be inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings. If a court were to find the exclusive forum provision contained in the Company's Charter to be inapplicable or unenforceable in an action, the Company might incur additional costs associated with resolving such action in other jurisdictions.

40 <br>

**DILUTION**

Our net tangible book value as of September 30, 2022 was approximately $1.9 million, or $0.80 per share. Net tangible book value per share is determined by dividing our total tangible assets, less total liabilities, by the number of shares of our common stock outstanding as of September 30, 2022. Dilution with respect to net tangible book value per share represents the difference between the amount per share paid by purchasers of shares of common stock in this offering and the net tangible book value per share of our common stock immediately after this offering.

After giving effect to the sale of 321,207 shares of our common stock and accompanying common warrant in this offering at a public offering price of $2.90 per share of common stock and accompanying warrant, and after giving effect to the sale of pre-funded warrants to purchase up to 2,265,000 shares of common stock and accompanying warrant at a public offering price of $2.89 per pre-funded warrant and accompanying warrant, and assuming the full exercise of the pre-funded warrants sold in this offering at an exercise price of $0.01 per share underlying the pre-funded warrants and after deducting estimated placement agent fees and estimated offering expenses payable by us, our as adjusted net tangible book value as of September 30, 2022 would have been approximately $8.7 million, or $1.74 per share. This represents an immediate increase in net tangible book value of $0.94 per share to existing stockholders and immediate dilution of $1.16 per share to investors purchasing our securities in this offering at the public offering price. The following table illustrates this dilution on a per share basis:

---

| | | |
|:---|:---|:---|
| Public offering price per share |  | $2.90 |
| Net tangible book value per share of as September 30, 2022 | $0.80 |  |
| Increase in net tangible book value per share attributable to this offering | $0.94 |  |
| As adjusted net tangible book value per share as of September 30, 2022, after giving effect to this offering |  | $1.74 |
| Dilution per share to new investors purchasing our common stock in this offering |  | $1.16 |

---

A $1.00 increase or decrease in the public offering price of $2.90 per share of common stock, would decrease the number of shares of our common stock offered in this offering by approximately 0.7 million shares or increase the number of shares of our common stock offered in this offering by approximately 1.4 million shares, respectively.

We may also increase or decrease the number of shares of common stock we are offering. An increase of 100,000 in the number of shares of common stock offered by us would increase our as adjusted net tangible book value by approximately $0.3 million, or $0.02 per share, and decrease the dilution per share to investors participating in this offering by $0.02 per share, assuming the offering price per share remains the same and after deducting the estimated placement agent commissions and estimated offering expenses payable by us. Similarly, a decrease of 100,000 in the number of shares of common stock offered by us would decrease our as adjusted net tangible book value by approximately $0.3 million or $0.02 per share, and increase the dilution per share to investors participating in this offering by $0.02 per share, assuming the offering price per share remains the same and after deducting the estimated placement agent commissions and estimated offering expenses payable by us. The information discussed above is illustrative only and will adjust based on the actual offering price, the actual number of shares of common stock we offer in this offering, and other terms of this offering determined at pricing.

The number of shares of common stock to be outstanding immediately after this offering is based on 2,416,925 shares of our common stock outstanding as of September 30, 2022, and excludes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· 108,001
 shares of common stock issuable upon the exercise of outstanding options granted as of September 30, 2022, under our equity incentive
 plans at a weighted average exercise price of $94.52 per share;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· 808,209
 shares of common stock issuable upon the exercise of outstanding warrants issued as of September 30, 2022, at a weighted average
 exercise price of $65.78 per share;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· 40,403
 shares of common stock issuable upon vesting of outstanding restricted stock units granted as of September 30, 2022;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· 68,251
 shares of common stock available for future issuance under our equity incentive plans as of September 30, 2022; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· 268,000 shares of common
 stock issued at a price of $7.00 per share, 215,000shares of common stock issued upon the exercise of pre-funded warrants at an offering
 price of $6.80 per share and 483,000 shares of common stock issuable upon the exercise of common warrants with an exercise price
 of $7.54 per share, each of which was issued after September 30, 2022 as part of our registered direct offering of securities completed
 in October 2022.

**BUSINESS**

***Overview***

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

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

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

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

&nbsp;&nbsp;&nbsp;&nbsp;· Following
 registration of the Unyvero instrument system as an in vitro diagnostics (IVD) platform for
 the Chinese market in early 2021, we are supporting our strategic partner Beijing Clear Biotech
 (BCB) in pursuing execution of a supplemental clinical trial with the Unyvero Hospitalized
 Pneumonia (HPN) test. As requested by the Chinese regulatory authority National Medical Products
 Administration (NMPA), this study is geared towards generating additional data in China that
 will complement a larger data set with data from abroad compiled from other clinical and
 analytical studies performed in the past. Due to continued impact of strict COVID-19 restrictions
 in China, this supplementary study has not yet been initiated and OpGen currently does not
 have visibility on the timelines for such a clinical study to start. In the third quarter
 of 2022, regulatory advisors to BCB informed OpGen that the NMPA has implemented a mandatory
 new electronic filing regime that requires the Company to re-submit its clinical trial plan
 under the new regime. The regulatory advisors estimate a total duration for the review and
 approval process to be between 24 to 30 months, and during that time, the clinical study
 is believed to take approximately 10 to 12 months.

&nbsp;&nbsp;&nbsp;&nbsp;· The
 Unyvero Urinary Tract Infection, or UTI, test, which is CE-IVD marked in Europe, is currently
 being made available to laboratories in the United States as a research use only, or RUO,
 kit. The test detects a broad range of pathogens as well as antimicrobial resistance markers
 directly from native urine specimens. We initiated a prospective multi-center clinical trial
 for the Unyvero UTI in the United States in the third quarter of 2021 and have recently completed
 enrollment of more than 1,800 patient samples. We currently expect to conclude reference
 testing in the coming months and expect unblinding in December 2022 as the next step towards
 a subsequent submission to the FDA.

43 <br>

&nbsp;&nbsp;&nbsp;&nbsp;· The
 Unyvero Invasive Joint Infection, or IJI, test, which is a variant being developed for the
 U.S. market, has also been selected for analytical and clinical performance evaluation on
 the Unyvero A30 platform including clinical trials towards a future submission to the FDA.
 Such clinical trial is not expected to start before the second quarter of 2023. Microbial
 diagnosis of IJI is difficult because of challenges in sample collection, usually at surgery,
 and patients being on prior antibiotic therapy which minimizes the chances of recovering
 viable bacteria. We believe that Unyvero IJI could be useful in identifying pathogens as
 well as their antimicrobial resistance, or AMR, markers to help guide optimal antibiotic
 treatment for these patients.

&nbsp;&nbsp;&nbsp;&nbsp;· On
 September 30, 2021, we received clearance from the FDA for our Acuitas AMR Gene Panel for
 bacterial isolates. The Acuitas AMR Gene Panel detects 28 genetic AMR markers in isolated
 bacterial colonies from 26 different pathogens. We believe the panel provides clinicians
 with a valuable diagnostic tool that informs about potential AMR patterns early and supports
 appropriate antibiotic treatment decisions in this indication. We signed two commercial customer
 contracts, and in October 2022, installed the first two systems for the Acuitas AMR Gene
 Panel for isolates and have a funnel of several additional commercial contract proposals
 that we expect to enter into during the coming quarters.

&nbsp;&nbsp;&nbsp;&nbsp;· On
 September 20, 2022, we signed a research and development collaboration agreement with the
 Foundation for Innovative New Diagnostics (FIND), the global alliance for diagnostics, which
 will fund the development of the Unyvero A30 *RQ* platform for use in low- and middle-income
 countries (LMICs). The initial project focuses on a feasibility study for the rapid detection
 of AMR markers from blood culture. The feasibility phase of this research and development
 project is set to conclude in the first half of 2023 and is funded by FIND for €0.7
 million.

&nbsp;&nbsp;&nbsp;&nbsp;· On
 October 25, 2022, we announced that our subsidiary Curetis and BioVersys AG, a Swiss biotech
 company developing novel antibiotics against drug resistant infections, signed a collaboration
 agreement. Under that collaboration agreement, BioVersys will be using the Unyvero systems
 and HPN test at all its sites for its upcoming BV100 phase II clinical trial.

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

&nbsp;&nbsp;&nbsp;&nbsp;· We
 have started offering validated high-quality sequencing and analysis services with rapid
 turnaround times for key applications in microbiology. The unique and differentiated offering
 for rapid and comprehensive genetic characterization of bacterial isolates and interpretive
 services include whole genome sequencing, taxonomic identification and typing, detection
 of plasmids, and other mobile elements, AMR, and virulence markers. Furthermore, the RUO
 services provided by OpGen's lab in Rockville, MD, will provide prediction of phenotypic
 antibiotic susceptibility based on our ARESdb database as well as specialized software for
 bacterial outbreak analysis via our AREScloud web application.

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

OpGen's combined AMR bioinformatics offerings, when and if such products are cleared for marketing, will offer important new tools to clinicians treating patients with AMR infections. OpGen's subsidiary Ares Genetics' ARESdb is a comprehensive database of genetic and phenotypic information. ARESdb was originally designed based on the Siemens microbiology strain collection covering resistant pathogens and its development has significantly expanded, as a result of transferring data from the discontinued Acuitas Lighthouse into ARESdb to now cover more than 90,000 bacterial isolates that have been sequenced using Next Generation Sequencing, or NGS, technology and tested for susceptibility with applicable antibiotics from a range of over 100 antimicrobial drugs. In the fourth quarter of 2021, Ares Genetics entered into a strategic database access deal with one of the world's leading microbiology and IVD corporations for their non-exclusive access to approximately 1.1% of Ares Genetics' total database asset at the time of signing. Ares Genetics continues to explore various discussions with several interested parties in potential future collaboration or licensing opportunities. Additional partnerships with a U.S. CLIA lab, a contract research organization ("CRO") and a major University Medical Center as well as the Belgian national reference laboratory at the University Hospital Leuven have been initiated and are ongoing and the collaboration master service agreement with Sandoz has recently been extended until January 2025.

44 <br>

In addition to potential future licensing and partnering, Ares Genetics intends to independently utilize the proprietary biomarker content in this database, as well as to build an independent business in NGS and Artificial Intelligence, or AI, based offerings for AMR research and diagnostics in collaboration with its current and potential future partners in the life science, pharmaceutical and diagnostics industries. Ares Genetics' customers for such offerings include Siemens Technology Accelerator and academic, public health, and biotechnology institutions from various European countries as new customers.

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

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

OpGen will continue to develop and seek FDA and other regulatory clearances or approvals, as applicable, for its Unyvero UTI and IJI products as well as for its Unyvero A30 *RQ* platform. OpGen will continue to offer the FDA-cleared Unyvero LRT and LRT BAL Panels, and FDA-cleared Acuitas AMR Gene Panel tests, as well as the Unyvero UTI Panel as RUO products to hospitals, public health departments, clinical laboratories, pharmaceutical companies and CROs in the United States. Curetis continues its efforts in ensuring compliance with the new In-Vitro-Diagnostic Device Regulation (IVDR) in the European Union (EU), which officially went into effect in May 2022. Given the lack of designated Notified Bodies at this time, and with the recently approved EU commission proposal to provide for generous multi-year grace periods for IVD products with former In-Vitro-Diagnostic Device Directive (IVDD) CE marking, it is now possible for Curetis to continue its portfolio of existing CE-IVD-marked products until at least May 2025 and May 2026, respectively, as long as no material changes are being made to any of its products. Following May 2022, however, any new or changed CE-marked products will be required to be IVDR compliant from the outset.

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

**OpGen's Products and Products in Development**

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

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

45 <br>

The Unyvero A50 Platform has been CE-IVD-marked since 2012 and is commercialized in Europe and certain other markets that accept CE-IVD-marking or where it has successfully passed the registration process (i.e. Colombia, Kuwait, and Singapore), and has been rolled out commercially in the United States following De Novo clearance of the Unyvero A50 System and the LRT Application Cartridge by the FDA in April 2018 and the 510(k) clearance of the LRT Application for BAL samples in December 2019.

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

OpGen aims to improve on this standard-of-care by offering comprehensive test information in a timely manner that allows for early, efficacious treatment, which OpGen believes results in improved clinical and health economic outcomes. The Company's Unyvero A50 Platform delivers results within four to five hours and can cover over 100 diagnostic targets. The broad Unyvero test panels also allow the identification of microorganisms that are difficult to culture and hence missed in culture-based test methods, as well as rare but critical pathogens not routinely tested for by standard methods, a conclusion confirmed by a number of clinical studies. The FDA clinical trial for the LRT Application Cartridge concluded that the Unyvero A50 System identified 32 positive atypical pathogen results in 1,653 prospectively tested specimens, as opposed to only four confirmed positive atypical pathogen results identified in 116 specimens from this cohort using traditional culture-based diagnostic methods. The Company believes this allows clinicians to make early adjustments to the specific treatment of the patient, saving significant time and cost, in particular by reducing the duration of the patient's hospital stay.

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

The Unyvero A50 Platform is marketed through a combination of direct sales in the United States and a growing network of distribution partners in Europe, Middle East, the ASEAN Region, Asia and Latin America. As of September 30, 2022, the distribution network comprises 12 distributors covering 28 countries in those regions with regulatory clearance for the Unyvero A50 System and the Unyvero Application Cartridges in some of these countries still pending.

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

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

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

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The UTI Application Cartridge,
 which addresses severe urinary tract infections and is CE-IVD-marked in Europe. The Company
 has begun analytical and clinical performance evaluations, including completion of enrollment
 of more than 1,800 patient samples into its clinical trial at the end of the third quarter
 of 2022. Data read out from that trial will be required for a subsequent submission to the
 FDA for clearance in 2023;

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

46 <br>

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

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

**The Unyvero A50 Platform**

Curetis launched its CE-IVD-marked Unyvero A50 Platform with a first disposable Application Cartridge for pneumonia in 2012. The FDA cleared the Unyvero A50 System and LRT Application Cartridge in April 2018 and the LRT BAL Application Cartridge in December 2019.

The Unyvero A50 Platform is a highly automated sample-to-answer molecular diagnostics platform, based on multiplexed end-point PCR with an array-based detection process. It integrates fully automated sample preparation, analysis and identification of disease relevant pathogens and antibiotic resistance markers to provide timely high-quality information to its end-users. The scalable system is designed to be either placed in laboratory settings or directly in hospital wards or intensive care units. Time-to-result is four to five hours for the different Application Cartridges commercially available today, including 30 minutes of automated sample preparation (lysis) and total hands-on time of no more than five minutes. The Unyvero A50 Platform's intuitive workflow with only minimal hands-on time enables untrained hospital staff to perform molecular tests at the point of need, such as intensive care units, or ICUs.

**Unyvero A50 Platform, System Components and Workflow**

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

***The Unyvero L4 Lysator***

The Unyvero L4 Lysator instrument is used for sample pre-processing and pathogen lysis. It performs proprietary software-controlled lysis of up to four samples, simultaneously within 30 minutes, combining mechanical, thermal, enzymatic and chemical lysis steps and allows the use of a wide range of native sample types due to a proprietary sample processing method (in respect of which several patents have been granted or are currently pending). Biofilm-forming pathogens can be detected by the Unyvero A50 Platform. In addition, the Unyvero A50 Platform is CE-IVD-marked for a broad variety of native patient sample types including sputum, (mini) BAL, tracheal aspirates, aspirates and exudates, catheter tips, pus, sonication fluid, synovial fluid, swabs and tissue. The lysis of further sample types such as blood, urine, stool and formalin-fixed paraffin embedded tissues is also possible with the proprietary Unyvero lysis method. Up to two Unyvero L4 Lysators can be attached to a single Unyvero C8 Cockpit to allow processing of up to eight samples simultaneously within 30 minutes.

***The Unyvero C8 Cockpit***

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

***The Unyvero A50 Analyzer***

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

***Workflow***

The Unyvero A50 Platform is a modular, flexible easy-to-use platform, which substantially reduces turnaround time from up to 24 hours or even weeks for traditional microbiology culture-based tests to approximately four to five hours. This allows physicians to adjust treatment at a much earlier stage than with the traditional microbiology culture-based test, which is the current clinical standard of care. OpGen believes that the reduced hands-on time of no more than five minutes and the intuitive workflow make the system operable by non-specialty trained laboratory personnel and reduce the risks of errors.

***Unyvero A50 Application Cartridge Portfolio***

Figure 3: Currently available Application Cartridges

***The HPN and LRT Application Cartridges***

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

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

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

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

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

&nbsp;&nbsp;&nbsp;&nbsp;· rare
 and difficult to detect pathogens like Legionella sp.

49 <br>

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

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

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

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

***The ITI Application Cartridge***

The ITI Application Cartridge was launched in May 2016 and is the second-generation version of the ITI Application Cartridge originally launched in the second quarter of 2014. Improvements were made to the panel and analytical performance as well as clinical sensitivity and specificity. It is a CE-IVD-marked Application Cartridge for the fully automated detection of currently 102 targets, covering 85 microorganisms and 17 antibiotic resistance markers for eight different clinical indications within the areas of prosthetic joint infections, surgical site infections, diabetic foot ulcers, catheter-associated infections, deep skin and tissue infections, cardiology-related infections, burn wounds and other implant infections. CE performance evaluation has demonstrated sensitivity of 86.9% at specificity of 99.2%. A diverse range of sample types such as aspirates and exudates, pus, sonication fluid, swabs, synovial fluid and tissue can be used on this Application Cartridge. Moreover, biofilm-forming pathogens can be identified by the Unyvero A50 Platform. The ITI Application Cartridge was jointly developed and co-funded with a worldwide market leader in orthopedic bone cement, which offers comprehensive infection management solutions. The Company pays a customer referral commission but has retained full control on product commercialization.

***The BCU Application Cartridge***

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

***The IAI Application Cartridge***

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

50 <br>

***The UTI Application Cartridge***

The UTI Application Cartridge was launched in April 2018. It is a CE-IVD-marked Application Cartridge for the fully automated detection of up to 103 diagnostic targets, covering 88 microorganisms and 15 genetic resistance markers for the areas of severe urinary tract infections in patients with anatomical, structural and functional alterations, renal impairments, impaired immune status, catheter-associated UTI, patients failing to respond to therapy and suffering from severe manifestations, urosepsis. OpGen estimates that the addressable market for the UTI Application Cartridge is 1.6 million cases eligible for testing per year in the EU and the United States. The UTI Application Cartridge is also available as RUO in the United States since 2020. As part of our portfolio strategy update in the fourth quarter of 2020, we decided to proceed with the analytical and clinical performance evaluation including clinical trials required for a subsequent submission to the FDA for this Application Cartridge and initiated clinical trials in the third quarter of 2021. We completed enrollment of over 1,800 patient samples into a prospective multi-center clinical trial at the end of the third quarter of 2022. Data read out from that trial will be required for a subsequent submission to the FDA in 2023.

**Ares Genetics' NGS and Bioinformatics Services for Molecular Microbiology**

OpGen's other core business in NGS and bioinformatics based solutions for molecular microbiology is operated by its wholly-owned subsidiary Ares Genetics GmbH, or Ares Genetics, or Ares, founded in 2017 and based in Vienna, Austria. Ares Genetics' business is based on the proprietary ARES Technology Platform and Ares Genetics' proprietary genetic database on AMR, ARESdb. The ARES Technology Platform and ARESdb build and expand upon the GEAR assets acquired from Siemens Technology Accelerator GmbH in 2016. On the bioinformatics side, OpGen has combined data from its now discontinued Acuitas Lighthouse with the Ares Genetics (Ares) data into the ARESdb. Ares Genetics believes ARESdb is a unique comprehensive database on the genetics of antibiotic resistance currently including data from over 90,000 sequenced isolates and phenotypic data on over 100 antibiotics. Ares Genetics also pursues an active out-licensing and collaboration strategy with suitable partners in the life science, pharmaceutical, and diagnostic industry to jointly develop solutions for microbiology relying on the database and/or the Ares Technology Platform. Ares Genetics entered into its first partnering and strategic collaborations with Qiagen, Sandoz, and in 2021 entered into strategic data access deal with one of the world's leading microbiology and IVD corporations which obtained non-exclusive access to approximately 1.1% of Ares Genetics' then-current datasets.

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

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

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

**OpGen's Acuitas AMR Gene Panel**

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

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

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

**Market Overview**

**Antibiotic Resistance – An Urgent Global Issue**

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

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

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

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

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

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

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

**Commercial Sales**

We currently sell and market our products and services directly in the United States through a dedicated sales and marketing support team. Internationally, we sell our products through a network of 12 distributors covering 28 countries.

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

**Competition**

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

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

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

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

***Competition to the Unyvero System***

The Unyvero A50 Platform is a sample-to-answer MDx solution. There are several other companies who develop and commercialize similar systems. In terms of devices and assays, OpGen believes its key competitors include bioMérieux (BioFire with its FilmArray® platform), GenMark (now a subsidiary of Roche) with its ePlex® platform, and Accelerate Diagnostics with its Pheno™. Taking into consideration the broader market, devices of other key competitors can be extended to include Cepheid (GeneXpert®), T2 Biosystems (T2DX®), Luminex Corporation (formerly known as Nanosphere; now acquired by DiaSorin) (Verigene System® and Aries®), Becton-Dickinson (BD Max™), Binx Health (with io™ System), Roche (Cobas® Liat® and GeneWEAVE), Qiagen (QIAstat-Dx™) and Biocartis N.V (Idylla™), Bosch (Vivalytic platform), SpeeDx (Plex/Resistance), and the Meridian Bioscience (formerly GenePOC) Revogene® system. Disease-related assay competitors including those providing reagent kits only (e.g. Seegene, Fast-Track Diagnostics/Siemens Healthineers, Genetic Signatures) and developers of laboratory developed tests (LDT) have to be separately assessed by each application. OpGen believes that its Unyvero A50 Platform has certain key characteristics that clearly differentiate it from other sample-to-answer systems:

53 <br>

Based on its corporate market analysis, OpGen believes that due to the proprietary lysis technology its Unyvero A50 Platform is able to process a broader variety of sample types than competing platforms. In most cases, no labor or time intensive manual sample preparation is necessary and even difficult and blood-contaminated native samples can be processed. Furthermore, the Unyvero A50 Platform is CE-IVD-marked for a variety of samples including sputum, bronchoalveolar lavage, tracheal aspirate, exudate, catheter tip, pus, sonication fluid, synovial fluid, swab and tissue. Further samples such as blood, urine, stool and formalin-fixed paraffin embedded tissues present further options for extending the variety of samples for future applications. Fresh or frozen samples as well as samples that have been stored in different media can be processed easily on the Unyvero A50 Platform. As the lysis is integrated into the workflow, hands-on time and potential handling errors are significantly reduced.

The Unyvero A50 Platform is also differentiated from competing products by its high multiplexing capability based on end-point PCR, which allows for the execution of eight independent multiplex PCR reactions simultaneously. Therefore, Unyvero can identify a broad range of microorganisms and a large variety of antibiotic resistance markers in a single run.

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

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

***Competition to the Unyvero Application Cartridges***

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

***Competition by Conventional Microbiology***

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

***Competition by Molecular Diagnostics – PCR***

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

***Competition to Ares Genetics***

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

***Competition by Molecular Diagnostics – NGS***

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

***Competing AMR Databases & Bioinformatics Solutions***

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

**Research and Development**

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

Our ongoing and anticipated research and development efforts include:

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Development
 of Unyvero A30 *RQ* platform including an IJI cartridge as well as the AMR panel from
 blood culture bottles under our research and development collaboration with FIND;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Data
 read out from clinical trial that completed enrollment at the end of the third quarter of
 2022 with more than 1,800 patient samples, and subsequent regulatory filing with the FDA
 for Unyvero UTI in the United States;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Clinical
 trials and regulatory filings for Unyvero IJI in the United States (expected as De Novo with
 clinical trial at a minimum of three trial sites and minimum of 1,500 samples tested)

**Sales and Marketing**

We currently sell and market our products and services directly in the United States through a dedicated sales and marketing support team. Internationally, we sell our products through 12 distributors covering 28 countries.

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

***Customers***

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

***Sales Process***

The typical sales process starts with an introductory visit to the microbiology laboratory director and senior microbiology staff. The goal is to introduce Unyvero or Acuitas and assess general interest in evaluating the products during a demonstration phase. However, the goal is also to initiate contact to any new hospital customer via the gatekeeping microbiology laboratory function. The primary objective apart from getting a demo phase agreed upon is to seek joint introductory meetings with the senior microbiology staff and the various intensive care units, or ICUs, and clinicians in any relevant ICU as well as the relevant member(s) of the antimicrobial stewardship team. Since there can be multiple ICUs (sometimes over a dozen in major university hospitals) with multiple 24/7 rotating shift operations each, it is paramount to identify one or a few key ICUs as internal product champions. The clinicians are ultimately the end-customers of Application Cartridge/Panel results for use in treatment assessment and optimizing medical care for their patients. They will also be the ones routinely requesting a test to be done. At this stage a discussion about the ideal placement of the Unyvero System during a demonstration usually takes place. In the United States, the Unyvero System is placed in the core laboratory. In the EU and the rest of world, or RoW, central location in the microbiology laboratory is the preferred option, or alternatively near patient ICU placement. We believe it is also important to engage the clinical pharmacy community, and specifically infectious disease pharmacists, in the sales process as an additional key stakeholder and decision maker.

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

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

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

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

56 <br>

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

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

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

***Distribution Channels***

To distribute the Unyvero A50 System and the Application Cartridges, OpGen has adopted a dual approach combining direct sales in the United States with indirect sales through specialized distributors in several countries of Europe, the Middle East, Asia, and Latin America (see section "Indirect Sales Markets" for a detailed list).

As of September 30, 2022, OpGen had an installed base of approximately 200 Unyvero A50 Analyzers across global markets.

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

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

***Direct Sales U.S. Market***

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

As of September 30, 2022, OpGen had an installed base of approximately 30 Unyvero A50 Analyzers across the United States and in different types of hospitals and laboratories.

***Indirect Sales Markets***

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

57 <br>

OpGen, through its subsidiary Curetis, has entered into distribution agreements with 12 distributors covering 32 countries. Distribution agreements usually feature minimal sales commitments and purchase commitments of the Unyvero A50 Systems and Application Cartridges commensurate with the size and structure of the respective market. The Company has several distribution agreements in place for the following European countries:

▪ *A. Menarini Diagnostics S.r.l*.: Austria, Belgium, France, Germany, Greece, Italy, Luxemburg,
 Netherlands, Portugal, Spain, Switzerland, United Kingdom;

▪ *Ako Med d.o.o.*: Bosnia and Hercegovina, Croatia, Montenegro, North Macedonia, and Serbia;

▪ *Synttergy Consult LTD*: Romania

▪ *BioLine LLC* <sup>[1]</sup>: Kazakhstan, Russia, and Ukraine;

▪ *BioLine BS LLC* <sup>[2]</sup>: Belarus; and

▪ *Kosova Export Import Supply Pharmaceutical (KEIS) Sh.p.k.*: Kosovo.

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

· cater
 for local product registrations as required;

· perform
 local clinical studies as required;

· take
 responsibility for local marketing based on guidelines and materials provided by Curetis'
 global marketing team;

· maintain
 regulatory compliance as required;

· maintain
 a local inventory; and

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

Outside of the EU, distribution agreements are in place for the following countries:

· *Future Horizons Scientific*: Egypt;

· *Advanced Technology Co. (ATC)*: Kuwait

· *Leader Medical Supplies Trading L.L.C.*: Qatar and the United Arab Emirates (UAE);

· *Acumen Research Laboratories Pte Ltd.*: Singapore;

· *Beijing Clear Bio-tech Co. Ltd. (BCB)*: China and Taiwan;;

· *Quimica Valaner*: Mexico; and

· *Annar Diagnostica Import SAS*: Colombia

The total contractual minimum purchase requirements of all current distributors are 372 Unyvero A50 Systems of which about 350 are part of BCB's commitment, which applies over an eight year period following market approval in China by the National Medical Products Association (NMPA), plus approximately 1.5 million Application Cartridges which are also part of BCB's commitment during the same period. Failure of distributors to reach minimum purchase quantities can lead to a termination of the distribution agreements or termination of exclusivity in territories for such distributor at the sole discretion of OpGen and its Curetis subsidiary. The above minimum purchase requirements do not guarantee any certain minimum future levels of revenues.

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

**Manufacturing**

During 2022, we manufactured all our Unyvero products in Germany (Unyvero systems are manufactured by our German supplier Zollner Elektronik AG, or Zollner, and Unyvero cartridges and consumables at our own manufacturing facility in Bodelshausen, Germany), and all our FDA-cleared Acuitas AMR products at our new headquarters in Rockville, Maryland. The Acuitas AMR product manufacturing is currently being transferred to Curetis in Germany, which transfer is expected to be completed in 2023.

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

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

Curetis' EMS (Electronic Manufacturing Services) provider Zollner is an established and experienced medical device manufacturer for large global companies and has flexible production processes ensuring it can meet demands with different volume requests. The Company's management believes that manufacturing capacity will not become a bottleneck in the foreseeable future as inventory levels are sufficient to support anticipated demand for the coming years. Zollner also has all required certifications under all applicable ISO standards for IVD instrument manufacture and is an FDA registered establishment for the manufacturing of the Unyvero A50 instruments. To date, no decision has been made on the selection of the original equipment manufacturer (OEM) for the series production of the Unyvero A30 *RQ* systems. Unyvero A30 *RQ* systems are so far being produced in pilot batches by DMT Produktentwicklung GmbH as the current German development partner to Curetis.

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

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

***Zollner***

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

The framework agreement has been expanded by a development agreement in 2010 and related project agreements for various development projects as well as by a strategic supply agreement signed in June 2013 under which Zollner became the OEM contract manufacturer for all Unyvero A50 instrument for Curetis.

59 <br>

***Scholz***

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

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

Under the framework agreement with Scholz, Curetis in 2018 also commissioned several single- and multi-cavity injection models for parts of the Unyvero A30 *RQ* cartridge. These injection molds were developed, manufactured and put into service by Scholz over the course of 2018 and 2019 under the same terms as described above for the injection molds for the Unyvero A50 cartridges.

***Supply Agreements***

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

***Raw Materials and Suppliers for Acuitas***

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

**Seasonality of Business**

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

**Quality Assurance**

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

60 <br>

**Payments and Reimbursements**

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

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

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

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

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

**Intellectual Property**

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

As of September 30, 2022, OpGen had a patent portfolio of 55 granted patents and 12 patent applications. 32 of the granted patents and 4 of the pending patent applications are from Curetis and 20 of the granted patents and 8 of the pending patent applications are from Ares Genetics. As part of such portfolio, we have three granted U.S. patents related to our Acuitas products.

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

61 <br>

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

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

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

**Regulation**

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

**Federal Oversight of Research-Use-Only Products**

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

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

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

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

**FDA's Premarket Clearance and Approval Requirements**

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

62 <br>

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

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

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

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

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

**510(k) Clearance Pathway**

We are currently working to submit our Unyvero tests for clearance under Section 510(k) of the FDC Act. Such tests are classified as medical devices, and we have to submit a premarket notification demonstrating that the proposed device is substantially equivalent to a previously cleared 510(k) device or a device that was in commercial distribution before May 28, 1976, for which the FDA has not yet called for the submission of premarket approval applications. FDA's 510(k) clearance pathway usually takes from three to twelve months; by statute, the FDA has 90 days to review the pre-market notification. On average the review time is approximately six months, but it can take significantly longer than twelve months in some instances (e.g. in the case of the Acuitas AMR Gene Panel as well as for the original Unyvero LRT products a total of over 18 months), as the FDA may require additional information, including clinical data, to make a determination regarding substantial equivalence.

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

**De Novo Classification Request**

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

63 <br>

**Premarket Approval Pathway**

A PMA application must be submitted if a device cannot be cleared through the 510(k) process. The PMA application process is generally more costly and time consuming than the 510(k) process. A PMA application must be supported by extensive data including, but not limited to, analytical, preclinical, clinical trials, manufacturing, statutory preapproval inspections, and labeling to demonstrate to the FDA's satisfaction the safety and effectiveness of the device for its intended use.

After a PMA application is sufficiently complete, the FDA will accept the application and begin an in-depth review of the submitted information. By statute, the FDA has 180 days to review the "accepted application," although, generally, review of the application can take between one and three years, but it may take significantly longer. During this review period, the FDA may request additional information or clarification of information already provided. Also, during the review period, an advisory panel of experts from outside the FDA may be convened to review and evaluate the application and provide recommendations to the FDA as to the approvability of the device. The preapproval inspections conducted by the FDA include an evaluation of the manufacturing facility to ensure compliance with the QSR, as well as inspections of the clinical trial sites by the Bioresearch Monitoring group to evaluate compliance with good clinical practice and human subject protections. New premarket approval applications or premarket approval application supplements are required for modifications that affect the safety or effectiveness of the device, including, for example, certain types of modifications to the device's indication for use, manufacturing process, labeling and design. Significant changes to an approved PMA require a 180-day supplement, whereas less substantive changes may utilize a 30-day notice, or the 135-day supplement. PMA supplements often require submission of the same type of information as a PMA application, except that the supplement is limited to information needed to support any changes from the device covered by the original PMA application and may not require as extensive clinical data or the convening of an advisory panel. None of our products are currently approved under a PMA.

***Clinical Trials***

Clinical trials are almost always required to support a De Novo or PMA application and are usually required to support non-exempt Class I and Class II 510(k) premarket submissions. Clinical trials may also be required to support certain marketing claims. If the device presents a "significant risk," as defined by the FDA, to human health, the FDA requires the device sponsor to file an investigational device exemption, or IDE application, with the FDA and obtain IDE approval prior to conducting the human clinical trials. The IDE application must be supported by appropriate data, such as analytical, animal and laboratory testing results, manufacturing information, and an Investigational Review Board, or IRB, approved protocol showing that it is safe to test the device in humans and that the testing protocol is scientifically sound. The IDE application must be approved in advance by the FDA prior to initiation of enrollment of human subjects. Clinical trials for a significant risk device may begin once the investigational device exemption application is approved by the FDA. If the clinical trial design is deemed to be "non-significant risk," the clinical trial may eligible for the "abbreviated" IDE requirements; in some instances IVD clinical trials may be exempt from the more burdensome IDE requirements if the test uses a noninvasive sampling method, does not introduce energy into the subject, and is not used in a diagnostic procedure without confirmation of the diagnosis by another established medically diagnostic procedure or product. All clinical trials conducted to support a PMA application must be conducted in accordance with FDA regulations and Federal and state regulations concerning human subject protection, including informed consent, oversight by an IRB and healthcare privacy requirements. A clinical trial may be suspended by the FDA or the IRB review board at any time for various reasons, including a belief that the risks to the study participants outweigh the benefits of participation in the study. Even if a study is completed, the results of our clinical testing may not demonstrate the safety and efficacy of the device or may be equivocal or otherwise not be sufficient to obtain approval of our product. Similarly, in Europe the clinical study must be approved by the local ethics committee and in some cases, including studies of high-risk devices, by the Ministry of Health in the applicable country.

64 <br>

**Pervasive and Continuing FDA Regulation**

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· product
 listing and establishment registration, which helps facilitate FDA inspections and other
 regulatory action;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· QSR,
 which requires manufacturers, including third-party manufacturers, to follow stringent design,
 testing, control, documentation and other quality assurance procedures during all aspects
 of the development and manufacturing process;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· labeling
 regulations and FDA prohibitions against the promotion of products for uncleared, unapproved
 or off-label use or indication;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· clearance
 of product modifications that could significantly affect safety or efficacy or that would
 constitute a major change in intended use of one of our cleared devices;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· approval
 of product design modifications that affect the safety or effectiveness of one of our cleared
 devices;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· medical
 device reporting regulations, which require that manufacturers comply with FDA requirements
 to report if their device may have caused or contributed to a death or serious injury, or
 has malfunctioned in a way that would likely cause or contribute to a death or serious injury
 if the malfunction of the device or a similar device were to recur;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· post-approval
 restrictions or conditions, including post-approval study commitments;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· post-market
 surveillance regulations, which apply when necessary to protect the public health or to provide
 additional safety and effectiveness data for the device;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the
 FDA's recall authority, whereby it can ask, or under certain conditions order, device
 manufacturers to recall from the market a product that is in violation of governing laws
 and regulations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· regulations
 pertaining to voluntary recalls; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· notices
 of corrections or removals.

OpGen's Rockville, Maryland facility is currently registered as a manufacturer with the FDA to manufacture our Acuitas products, whereas the Curetis facility in Bodelshausen, Germany is registered with the FDA for all Unyvero cartridge and consumable manufacturing. We commenced transferring the manufacturing of the Acuitas products to Curetis and expect to complete such transfer in 2023. We and any third-party manufacturers are subject to announced and unannounced inspections by the FDA to determine our compliance with quality system regulation and other regulations.

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

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

***Health Insurance Portability and Accountability Act***

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

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

65 <br>

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

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

**Federal and State Physician Self-referral Prohibitions**

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

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

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

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· denial
 of payment for the services provided in violation of the prohibition;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· refunds
 of amounts collected by an entity in violation of the Stark Law;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· a
 civil penalty of up to $15,000 for each service arising out of the prohibited referral;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· possible
 exclusion from Federal healthcare programs, including Medicare and Medicaid; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· a
 civil penalty of up to $100,000 against parties that enter into a scheme to circumvent the
 Stark Law's prohibition.

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

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

**Federal and State Anti-Kickback Laws**

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

66 <br>

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

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

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

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

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

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

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

**Other Federal and State Fraud and Abuse Laws**

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

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

67 <br>

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

**International Regulation**

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

**Environmental Matters**

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

**Human Capital Resources**

As of September 30, 2022, we had 99 employees worldwide, with 22 employed at OpGen, Inc. in the United States, 62 employed at Curetis GmbH in Germany, and 15 employed at Ares Genetics GmbH in Austria. Of our 99 worldwide employees, 84 are full-time employees. Except for the managing director of Ares Genetics, our Austria-based employees are subject to a collective bargaining agreement for employees of companies in the automated data processing and IT services industry. None of our other employees worldwide are subject to a collective bargaining arrangement. The 22 employees in the United States work in our Rockville, Maryland location or are field based marketing, sales, and service employees.

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

*Culture*

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

*Compensation*

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

68 <br>

*Health & Wellness*

The physical health and wellbeing, life balance and mental health of our employees is vital to our success. Throughout 2021 and 2022, health and wellness was a key focus of the Company, especially in light of the COVID-19 pandemic. Many of our employee communications focused on the physical and mental health of our employees. We remain committed to providing our workforce with flexible remote working schedules to suit their personal needs through this challenging time. We also continue to benchmark all of our health insurance offerings to ensure plan competitiveness.

Throughout the COVID-19 pandemic, employee safety has been a top priority. Ongoing safety measures were put into place at each of our locations including implementing pre-screening and social distancing requirements in addition to providing personal protective equipment and regular testing of staff wherever possible.

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 amended (the "Exchange Act"), and have elected to provide in this prospectus certain scaled disclosures permitted under the Exchange Act for smaller reporting companies.

**Executive Compensation Overview**

Following the completion of the Company's business combination transaction with Curetis GmbH in 2020, the Compensation Committee and the Board have worked with management to update the Company's executive compensation program to (1) highlight the importance of equity-based compensation to the Company's named executive officers, (2) evaluate and assess the Company's executive compensation relative to peer companies, and (3) utilize performance-based bonuses as a critical portion of total compensation.

The Company believes it is vital to link executive compensation to corporate performance and to create incentives for management to enhance Company value. In accordance with its compensation philosophy, the Company seeks to attract and retain employees through salary levels that are competitive with the local market and similarly situated companies but generally to follow the market rather than lead the market, particularly with respect to cash compensation, and offer attractive equity and cash-based incentive components to align compensation with Company performance objectives. In addition, given the Company's early commercial stage, the Company believes it is important to emphasize equity compensation in order to help the Company retain cash and incentivize its employees.

The Compensation Committee utilized third party services and data to compile relevant compensation from companies that are similarly situated to the Company. The Compensation Committee utilized such data to determine the base salary, bonus opportunity and equity compensation for our named executive officers.

**Summary Compensation Table for 2022 and 2021**

Our named executive officers for 2022 are Oliver Schacht, Ph.D., our Chief Executive Officer, Albert Weber, our Chief Financial Officer, and Johannes Bacher, our Chief Operating Officer. This table below provides disclosure, for the years ended December 31, 2022 and 2021 for our named executive officers.

**Agreements with Our Named Executive Officers**

*Retention Plan*

On September 21, 2018, the Board approved a Retention Plan for Executives, or the "Retention Plan." The Company considers the establishment and maintenance of a sound and vital management team to be essential to protecting and enhancing the best interests of the Company and its stockholders. In this connection, the Company recognizes that, as is the case with many publicly held corporations, the possibility of a change in control may arise and that such possibility, and the uncertainty and questions which it may raise among management, may result in the departure or distraction of management personnel to the detriment of the Company and its stockholders. Accordingly, the Board has determined that appropriate steps should be taken to reinforce and encourage the continued attention and dedication of members of the Company's management to their assigned duties without distraction in circumstances arising from the possibility of a change in control of the Company. The executive officers of the Company, as that term is defined under the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder, are the eligible participants in the Retention Plan, or the "Executives." The Executives include Oliver Schacht, Albert Weber and Johannes Bacher.

The initial term of the Retention Plan was three (3) years. Its term is automatically extended for one (1) year terms thereafter unless the Company provides notice of termination to the Executives at least six (6) months before the termination date; provided, that if a change in control (as defined in the Retention Plan) does occur, the term is then set at two (2) years after the date of the change in control.

The Retention Plan provides for Units to be awarded to the Executives, which can be issued in fractional Units, with each Unit equal to one percent (1%) of the "transaction value" of a change in control transaction. A total of four Units are available for award under the Retention Plan. In 2021, the Board granted one Unit to each of Mr. Schacht and Mr. Bacher, and in 2022, the Board granted one Unit to Mr. Weber.

"Transaction value" means all economic value of a change in control transaction to the Company, including any debt or other obligations assumed by the surviving entity in the transaction, amounts paid to the Company or its stockholders, milestone payments, earn-outs and forgiveness of indebtedness. For purposes of this definition, (i) in the case of the sale, exchange or purchase of the Company's equity securities, the total consideration paid for such securities (including amounts paid to holders of options, warrants and convertible securities), and (ii) in the case of a sale or disposition by the Company of assets, the total consideration paid for such assets, plus the net value of any current assets not sold by the Company.

The Units will vest and be payable only in the event an Executive has a "qualifying termination" during a defined change in control period, or remains employed by the Company or its successor at the termination date of the Retention Plan. A "qualifying termination" is a termination without cause by the Company or a termination for good reason by the Executive in the change in control period that spans from six (6) months before the change in control to the second anniversary after the change in control consummation.

The Retention Plan is binding on any successor to the Company.

*Employment Agreements*

*Oliver Schacht* 

On October 29, 2020, the Company entered into an Executive Employment Agreement with Oliver Schacht, Ph.D., the Company's Chief Executive Officer. The employment agreement superseded the (1) Management Services Agreement, dated as of April 2, 2020, by and between the Company and Mr. Schacht, and (2) the Managing Director's Employment Contract, dated as of August 6, 2020, by and between Curetis GmbH, a wholly-owned subsidiary of the Company, and Mr. Schacht (collectively, the "Prior Agreements"), each of which were terminated, except as expressly provided in the Mr. Schacht's employment agreement.

74 <br>

Consistent with the Prior Agreements, Mr. Schacht's employment agreement provides that Mr. Schacht will receive an annual base salary of $408,000 per year and will be eligible to receive an annual bonus of up $285,600, or seventy percent (70%) of the base salary. The annual bonus opportunity will be based on key performance metrics established by the Board of Directors of the Company. Mr. Schacht will be entitled to participate in the Company's standard equity incentive and benefits plans.

The employment agreement extends through September 1, 2021, unless sooner terminated in accordance with its terms. Thereafter, the employment agreement automatically renews for successive one year terms, unless either party provides notice of termination at least three months before the commencement of any renewal term. Under the employment agreement, Mr. Schacht is subject to customary restrictive covenants, including a requirement not to compete with the Company while the employment agreement is in effect.

Pursuant to the employment agreement, if Mr. Schacht is terminated without cause or his employment is voluntarily terminated for good reason, or during a change in control, he will receive (a) his annual base salary for a period of twelve (12) months, (b) acceleration of any outstanding options, restricted stock units, or equity awards, and (c) reimbursement for the cost of continued healthcare coverage for up to six (6) months. If the Company provides timely notice of a non-renewal of the employment agreement, Mr. Schacht is entitled to receive (a) severance for a period of nine (9) months, and (b) reimbursement for the cost of continued healthcare coverage for up to nine (9) months following expiration of the Agreement. All severance payments are contingent on Mr. Schacht's signing and not revoking a release of claims and compliance with the terms of the Employment Agreement.

*Johannes Bacher*

On April 6, 2020, the Company entered into a Managing Director's Employment Contract with Mr. Bacher, pursuant to which he will serve as the Chief Operating Officer of the Company. Mr. Bacher's employment agreement provides that Mr. Bacher will receive a base salary of $300,000 per year and will be eligible to receive an annual bonus of up to forty-five percent (45%) of the base salary. The annual bonus opportunity will be based on key performance metrics established by the Board and the Compensation Committee. Mr. Bacher will also be entitled to participate in the Company's 2015 Equity Incentive Plan, under which awards will be made consistent with the timing made to the Company's other officers.

In the event of a change of control (as defined in the Mr. Bacher's employment agreement), Mr. Bacher will have a one-time right to terminate his employment agreement upon three-months' notice. In the event of such termination of Mr. Bacher's employment agreement, Mr. Bacher is entitled to his salary and variable annual bonus for a period of six months after the end of the agreement.

Pursuant to his employment agreement, Mr. Bacher is subject to customary restrictive covenants, including a requirement not to compete with the Company and its affiliates anywhere in the world for a period of two years after termination of the agreement.

*Albert Weber*

Effective January 1, 2022, the Company entered into a Managing Director's Employment Contract with Mr. Weber, pursuant to which he will serve as the Chief Financial Officer of the Company. Mr. Weber's employment agreement provides that Mr. Weber will receive a base salary of $300,000 per year and will be eligible to receive an annual bonus of up to forty-five percent (45%) of the base salary. The annual bonus opportunity will be based on key performance metrics established by the Board and the Compensation Committee. Mr. Weber will also be entitled to participate in the Company's 2015 Equity Incentive Plan, under which awards will be made consistent with the timing made to the Company's other officers.

In the event of a change of control (as defined in the Mr. Weber's employment agreement), Mr. Weber will have a one-time right to terminate his employment agreement upon three-months' notice. In the event of such termination of Mr. Weber's employment agreement, Mr. Weber is entitled to his salary and variable annual bonus for a period of six months after the end of the agreement.

Pursuant to his employment agreement, Mr. Weber is subject to customary restrictive covenants, including a requirement not to compete with the Company and its affiliates anywhere in the world for a period of two years after termination of the agreement.

In addition, upon commencement of employment on January 1, 2022, Mr. Weber was awarded 10,500 options to purchase common stock (as adjusted for the 2023 Reverse Stock Split) that will vest over four years in accordance with the terms of the Company's 2015 Equity Incentive Plan.

75 <br>

*Glossary of Terms*

For purposes of the Agreements and the Retention Plan, the following terms have the following meanings (where applicable):

"cause" means (i) executive's commission of a felony; (ii) any act or omission of executive constituting dishonesty, fraud, immoral or disreputable conduct that causes material harm to the Company; (iii) executive's violation of Company policy that causes material harm to the Company; (iv) executive's material breach of any written agreement between executive and the Company which, if curable, remains uncured after notice; or (v) executive's breach of fiduciary duty. The termination of executive's employment as a result of the death or disability is not deemed to be a termination without cause.

"change in control" means:

(i) a transaction or series of transactions (other than an offering of common stock to the general public through a registration statement filed with the SEC) whereby any "person" or related "group" of "persons" (as such terms are used in Sections 13(d) and 14(d)(2) of the Exchange Act (other than the Company, any of its subsidiaries, an employee benefit plan maintained by the Company or any of its subsidiaries or a "person" that, prior to such transaction, directly or indirectly controls, is controlled by, or is under common control with, the Company) directly or indirectly acquires beneficial ownership (within the meaning of Rule 13d-3 under the Exchange Act) of securities of the Company possessing more than 50% of the total combined voting power of the Company's securities outstanding immediately after such acquisition; or

(ii) the consummation by the Company (whether directly involving the Company or indirectly involving the Company through one or more intermediaries) of (x) a merger, consolidation, reorganization, or business combination or (y) a sale or other disposition of all or substantially all of the Company's assets in any single transaction or series of related transactions or (z) the acquisition of assets or stock of another entity, in each case other than a transaction: (1) which results in the Company's voting securities outstanding immediately before the transaction continuing to represent (either by remaining outstanding or by being converted into voting securities of the Company or the person that, as a result of the transaction, controls, directly or indirectly, the Company or owns, directly or indirectly, all or substantially all of the Company's assets or otherwise succeeds to the business of the Company (the Company or such person, the Successor) directly or indirectly, at least a majority of the combined voting power of the Successor's outstanding voting securities immediately after the transaction, and (2) after which no person or group beneficially owns voting securities representing 50% or more of the combined voting power of the Successor; provided, however, that no person or group shall be treated for purposes of this definition as beneficially owning 50% or more of the combined voting power of the Successor solely as a result of the voting power held in the Company prior to the consummation of the transaction; or

(iii) the Company's stockholders approve a liquidation or dissolution of the Company.

"good reason" means any of the following, without executive's consent: (i) a material diminution of executive's responsibilities or duties (provided, however, that the acquisition of the Company and subsequent conversion of the Company to a division or unit of the acquiring company will not by itself be deemed to be a diminution of executive's responsibilities or duties); (ii) material reduction in the level of executive's base salary (and any such reduction will be ignored in determining executive's base salary for purposes of calculating the amount of severance pay); (iii) relocation of the office at which executive is principally based to a location that is more than fifty (50) miles from the location at which executive performed his duties immediately prior to the effective date of a change in control; (iv) failure of a successor in a change in control to assume the severance agreement; or (v) the Company's material breach of any written agreement between executive and the Company. Notwithstanding the foregoing, any actions taken by the Company to accommodate a disability of executive or pursuant to the Family and Medical Leave Act shall not be a good reason for purposes of the agreement. Additionally, before executive may terminate employment for a good reason, executive must notify the Company in writing within thirty (30) days after the initial occurrence of the event, condition or conduct giving rise to good reason, the Company must fail to remedy or cure the alleged good reason within the thirty (30) day period after receipt of such notice if capable of being cured within such thirty-day period, and, if the Company does not cure the good reason (or it is incapable of being cured within such thirty-day period), then executive must terminate employment by no later than thirty (30) days after the expiration of the last day of the cure period (or, if the event condition or conduct is not capable of being cured within such thirty-day period, within thirty (30) days after initial notice to the Company of the violation). Transferring executive's employment to a successor is not itself good reason to terminate employment under the agreement, provided, however, that subparagraphs (i) through (v) above shall continue to apply to executive's employment by the successor. This definition is intended to constitute a "substantial risk of forfeiture" as defined under Treasury Regulation 1.409A-1(d).

**Director Compensation**

Our Board of Directors has 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 receives 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, each new non-employee director receives an initial equity grant and each non-employee director receives an annual equity grant. Under such program, each non-employee director receives an initial grant of 30,000 restricted stock units and an annual grant to non-employee directors of 15,000 restricted stock units. All such awards are made under the 2015 Plan. The annual equity award may be pro-rated in the first year of service depending on when the non-employee director joins the Board or may be deferred until the following year.

Dr. Schacht does not receive additional compensation for his service on the Board. See "Summary Compensation Table" for his 2022 compensation.

Compensation for the non-employee directors for the year ended December 31, 2022 was:

 are determined in accordance with FASB Accounting Standards Codification 718 (ASC 718), without regard to any estimate of forfeiture

 Elsey (2,500), Fernandes (2,667) and Schlaeppi (0)

**Compensation Risk Assessment**

We believe that although a portion of the compensation provided to our executive officers and other employees is performance-based, our executive compensation program does not encourage excessive or unnecessary risk taking. This is primarily due to the fact that our compensation programs are designed to encourage our executive officers and other employees to recognize and support both short-term and long-term strategic goals, in particular in connection with our pay-for-performance compensation philosophy. As a result, we do not believe that our compensation programs are reasonably likely to have a material adverse effect on us.

**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. A total of 2,896 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.

78 <br>

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) 54,200 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, 2022, 66,101 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 160,000 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.

 

79 <br>

*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.

*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, 2021, 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.

80 <br>

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 6,713. 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 $42.40. 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 65,000 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 500,000 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.

81 <br>

*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.

*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.

**SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT**

The number of shares of the Company's common stock outstanding at the close of business on December 31, 2022 was 2,899,925 shares (as adjusted for the 2023 Reverse Stock Split). The following table sets forth the beneficial ownership of the Company's common stock, as of December 31, 2022, 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 December 31, 2022 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 December 31, 2022, 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.

**CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS**

Other than compensation arrangements described in this prospectus, there were and are no transactions or series of similar transactions, during our last three 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. Compensation arrangements for our directors and named executive officers are described elsewhere in this prospectus.

**DIVIDEND POLICY**

We have never declared or paid cash dividends on our common stock. We currently intend to retain our future earnings, if any, for use in our business and therefore do not anticipate paying cash dividends in the foreseeable future. Payment of future dividends, if any, will be at the discretion of our board of directors after taking into account various factors, including our financial condition, operating results, current and anticipated cash needs and plans for expansion.

**DESCRIPTION OF SECURITIES WE ARE OFFERING**

We are offering up to 321,207 shares of our common stock and pre-funded warrants to purchase up to 2,265,000 shares of our common stock along with Series A-1 warrants to purchase up to 2,586,207 shares of common stock and Series A-2 warrants to purchase up to 2,586,207 shares of common stock. Each share of common stock or pre-funded warrant is being sold together with a Series A-1 warrant to purchase one share of common stock and a Series A-2 warrant to purchase one share of common stock. The shares of common stock or pre-funded warrants and accompanying warrants will be issued separately. We are also registering the shares of common stock issuable from time to time upon exercise of the common warrants and pre-funded warrants offered hereby.

**Common Stock**

The description of our common stock offered by this prospectus is incorporated herein by reference to the description of such common stock included in our Annual Report on Form 10-K for the year ended December 31, 2021.

**Common Warrants**

The Company is also offering Series A-1 warrants to purchase up to an aggregate of 2,586,207 shares of our common stock and Series A-2 warrants to purchase up to an aggregate of 2,586,207 shares of our common stock.

Each common warrant issued in this offering represents the right to purchase up to one share of common stock at an initial exercise price of $2.65 per share. Each Series A-1 warrant may be exercised, in cash or by a cashless exercise at the election of the holder at any time following the date of issuance and from time to time thereafter through and including the five year anniversary of the initial exercise date. Each Series A-2 warrant may be exercised, in cash or by a cashless exercise at the election of the holder at any time following the date of issuance and from time to time thereafter through and including the eighteen month anniversary of the initial exercise date.

The common warrants will be exercisable in whole or in part by delivering to the Company a completed instruction form for exercise and complying with the requirements for exercise set forth in the common warrant. Payment of the exercise price may be made in cash or pursuant to a cashless exercise, in which case the holder would receive upon such exercise the net number of shares of common stock determined according to the formula set forth in the common warrants.

***No Fractional Shares***

No fractional shares or scrip representing fractional shares shall be issued upon the exercise of the common warrants. As to any fraction of a share which the holder would otherwise be entitled to purchase upon such exercise, the number of shares of common stock to be issued shall be rounded up to the nearest whole number.

***Failure to Timely Deliver Shares***

If we fail to deliver to the holder a certificate representing shares issuable upon exercise of a common warrant or to credit the holder's balance account with Depository Trust Company for such number of shares of common stock to which the holder is entitled upon the holder's exercise of the common warrant, in each case, by the delivery date set forth in the common warrant, and if after such date the holder is required by its broker to purchase (in an open market transaction or otherwise) or the holder's brokerage firm otherwise purchases, shares of common stock to deliver in satisfaction of a sale by the holder of the warrant shares which the holder anticipated receiving upon such exercise, or a Buy-In, then we shall (A) pay in cash to the holder the amount, if any, by which (x) the holder's total purchase price (including brokerage commissions, if any) for the shares of common stock so purchased exceeds (y) the amount obtained by multiplying (1) the number of warrant shares that we were required to deliver to the holder in connection with the exercise at issue, times (2) the price at which the sell order giving rise to such purchase obligation was executed, and (B) at the option of the holder, either reinstate the portion of the applicable warrant and equivalent number of warrant shares for which such exercise was not honored (in which case such exercise shall be deemed rescinded) or deliver to the holder the number of shares of common stock that would have been issued had we timely complied with our exercise and delivery obligations. In addition, if we fail to deliver to the holder any common stock pursuant to a validly-exercised common warrant, we will be required to pay liquidated damages in the amount of $10 per trading day for each $1,000 of the shares of common stock exercised but not delivered (and rising to $20 per trading day beginning the third trading day after the warrant share delivery date) until such time the shares of common stock are delivered or the holder rescinds such exercise.

85 <br>

***Exercise Limitation***

In general, a holder will not have the right to exercise any portion of a common warrant if the holder (together with its Attribution Parties (as defined in the common warrant)) would beneficially own in excess of 4.99% or 9.99%, at the election of the holder, of the number of shares of our common stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the common warrant. However, any holder may increase or decrease such percentage to any other percentage not in excess of 9.99% upon notice to us, provided that any increase in this limitation will not be effective until 61 days after such notice from the holder to us and such increase or decrease will apply only to the holder providing such notice.

***Cashless Exercise***

If, at the time a holder exercises its warrants, a registration statement registering the issuance of the shares of common stock underlying the warrants under the Securities Act, is not then effective or available for the issuance of such shares, then in lieu of making the cash payment otherwise contemplated to be made to us upon such exercise in payment of the aggregate exercise price, the holder may elect instead to receive upon such exercise (either in whole or in part) the net number of shares of common stock determined according to a formula set forth in the warrant.

***Adjustment for Stock Splits***

The exercise price and the number of shares of common stock purchasable upon the exercise of the common warrants are subject to adjustment upon the occurrence of specific events, including sales of additional shares of common stock, stock dividends, stock splits, and combinations of our common stock.

***Dividends or Distributions***

If we declare or make any dividend or other distribution of its assets (or rights to acquire its assets) to holders of shares of our common stock, by way of return of capital or otherwise (including, without limitation, any distribution of cash, stock or other securities, property, options, evidence of indebtedness or any other assets by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction) at any time after the issuance of the common warrants, then, in each such case, the holders of the common warrants shall be entitled to participate in such distribution to the same extent that the holders would have participated therein if the holders had held the number of shares of common stock acquirable upon complete exercise of the common warrants.

***Purchase Rights***

If we grant, issue or sell any shares of our common stock or securities exercisable for, exchangeable for or convertible into our common stock, or rights to purchase stock, common warrants, securities or other property pro rata to the record holders of any class of shares of our common stock, referred to as Purchase Rights, then each holder of the common warrants will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the holder could have acquired if the holder had held the number of shares of common stock acquirable upon complete exercise of the common warrants immediately before the record date, or, if no such record is taken, the date as of which the record holders of shares of common stock are to be determined, for the grant, issue or sale of such Purchase Rights.

***Fundamental Transaction***

If a Fundamental Transaction (as defined below) occurs, then the successor entity will succeed to, and be substituted for us, and may exercise every right and power that we may exercise and will assume all of our obligations under the common warrants with the same effect as if such successor entity had been named in the common warrant itself. Additionally, upon consummation of a Fundamental Transaction pursuant to which holders of shares of our common stock are entitled to receive securities or other assets with respect to or in exchange for shares of our common stock, we will make appropriate provision to ensure that the holder will thereafter have the right to receive upon an exercise of the common warrants at any time after the consummation of the Fundamental Transaction but prior to the applicable expiration date of the common warrants, in lieu of shares of our common stock (or other securities, cash, assets or other property) purchasable upon the exercise of the common warrant prior to such Fundamental Transaction, at the option of each holder (without regard to any limitation in the common warrant on the exercise of the common warrants), the number of shares of common stock of the successor or acquiring corporation or of us, if we are the surviving corporation, and any additional consideration which the holder would have been entitled to receive upon the happening of such Fundamental Transaction had the common warrants been exercised immediately prior to such Fundamental Transaction.

86 <br>

If holders of our common stock are given a choice as to the securities, cash or property to be received in a Fundamental Transaction, then the holder shall be given the same choice as to the consideration it receives upon any exercise of the common warrants, following such Fundamental Transaction. These provisions apply similarly and equally to successive Fundamental Transactions and other corporate events described in the common warrants and will be applied without regard to any limitations on the exercise of the common warrants.

***Transferability***

Subject to applicable laws, the common warrants may be offered for sale, sold, transferred or assigned. There is currently no trading market for the common warrants and a trading market is not expected to develop.

***Rights as a Stockholder***

Except as otherwise provided in the common warrants or by virtue of a holder's ownership of shares of our common stock, the holders of the common warrants do not have the rights or privileges of holders of our common stock, including any voting rights, unless and until they exercise their common warrants.

***Amendments***

The common warrants may be amended with the written consent of the holder of such common warrant and us.

***Listing***

There is no established public trading market for the common warrants, and we do not expect a market to develop. In addition, we do not intend to apply for listing of the common warrants on any national securities exchange.

***Definitions***

"<u>Black Scholes Value</u>" means the value of the common warrants based on the Black-Scholes Option Pricing Model obtained from the "OV" function on Bloomberg, L.P. ("<u>Bloomberg</u>") determined as of the day of consummation of the applicable Fundamental Transaction for pricing purposes and reflecting (A) a risk-free interest rate corresponding to the U.S. Treasury rate for a period equal to the time between the date of the public announcement of the applicable Fundamental Transaction and the Termination Date, (B) an expected volatility equal to the greater of 100% and the 100 day volatility obtained from the HVT function on Bloomberg (determined utilizing a 365 day annualization factor) as of the trading day immediately following the public announcement of the applicable Fundamental Transaction, (C) the underlying price per share used in such calculation shall be the greater of (i) the sum of the price per share being offered in cash, if any, plus the value of any non-cash consideration, if any, being offered in such Fundamental Transaction and (ii) the greater of (x) the last VWAP immediately prior to the public announcement of such Fundamental Transaction and (y) the last VWAP immediately prior to the consummation of such Fundamental Transaction and (D) a remaining option time equal to the time between the date of the public announcement of the applicable Fundamental Transaction and the Termination Date, and (E) a zero cost of borrow.

"<u>Fundamental Transaction</u>" means (i) we, directly or indirectly, in one or more related transactions effect any merger or consolidation with or into another Person, (ii) we or any subsidiary, directly or indirectly, effects any sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially all of our assets in one or a series of related transactions, (iii) any, direct or indirect, purchase offer, tender offer or exchange offer (whether by us or another Person) is completed pursuant to which holders of common stock are permitted to sell, tender or exchange their shares for other securities, cash or property and has been accepted by the holders of 50% or more of the outstanding common stock or 50% or more of the voting power of the common equity, (iv) we, directly or indirectly, in one or more related transactions effect any reclassification, reorganization or recapitalization of our common stock or any compulsory share exchange pursuant to which our common stock is effectively converted into or exchanged for other securities, cash or property, or (v) we, directly or indirectly, in one or more related transactions consummate a stock or share purchase agreement or other business combination (including, without limitation, a reorganization, recapitalization, spin-off, merger or scheme of arrangement) with another Person or group of Persons whereby such other Person or group acquires more than 50% of the outstanding shares of our common stock or 50% or more of the voting power of the common equity.

**Pre-Funded Warrants**

The following summary of certain terms and provisions of the pre-funded warrants that are being offered hereby is not complete and is subject to, and qualified in its entirety by, the provisions of the pre-funded warrant, the form of which is filed as an exhibit to the registration statement of which this prospectus forms a part. Prospective investors should carefully review the terms and provisions of the form of pre-funded warrant for a complete description of the terms and conditions of the pre-funded warrants.

***Duration and Exercise Price***

Each pre-funded warrant offered hereby will have an initial exercise price per share equal to $0.01. The pre-funded warrants will be immediately exercisable and may be exercised at any time until the pre-funded warrants are exercised in full. The exercise price and number of shares of common stock issuable upon exercise is subject to appropriate adjustment in the event of stock dividends, stock splits, reorganizations or similar events affecting our common stock and the exercise price.

***Exercisability***

Each pre-funded warrant may be exercised, in cash or by a cashless exercise at the election of the holder at any time following the date of issuance and from time to time thereafter until the pre-funded warrants are exercised in full. The pre-funded warrants will be exercisable in whole or in part by delivering to the Company a completed instruction form for exercise and complying with the requirements for exercise set forth in the pre-funded warrant. Payment of the exercise price may be made in cash or pursuant to a cashless exercise, in which case the holder would receive upon such exercise the net number of shares of common stock determined according to the formula set forth in the pre-funded warrant.

***Cashless Exercise***

At the time a holder exercises its pre-funded warrants, in lieu of making the cash payment otherwise contemplated to be made to us upon such exercise in payment of the aggregate exercise price, the holder may elect instead to receive upon such exercise (either in whole or in part) the net number of shares of common stock determined according to a formula set forth in the pre-funded warrants.

***Exercise Limitation***

In general, a holder will not have the right to exercise any portion of a pre-funded warrant if the holder (together with its Attribution Parties (as defined in the pre-funded warrant)) would beneficially own in excess of 4.99% or 9.99%, at the election of the holder, of the number of shares of our common stock outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the pre-funded warrant. However, any holder may increase or decrease such percentage to any other percentage not in excess of 9.99% upon notice to us, provided, that any increase in this limitation will not be effective until 61 days after such notice from the holder to us and such increase or decrease will apply only to the holder providing such notice.

***Transferability***

Subject to applicable laws, a pre-funded warrant may be transferred at the option of the holder upon surrender of the pre-funded warrant to us together with the appropriate instruments of transfer.

***Fractional Shares***

No fractional shares of common stock will be issued upon the exercise of the pre-funded warrants. Rather, the number of shares of common stock to be issued will, at our election, either be rounded up to the nearest whole number or we will pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the exercise price.

88 <br>

***Trading Market***

There is no trading market available for the pre-funded warrants on any securities exchange or nationally recognized trading system.

***Right as a Stockholder***

Except as otherwise provided in the pre-funded warrants or by virtue of such holder's ownership of shares of our common stock, the holders of the pre-funded warrants do not have the rights or privileges of holders of our common stock, including any voting rights, until they exercise their pre-funded warrants.

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

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

***Meetings of Stockholders***

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

***Advance Notice Requirements***

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

**Exclusive Jurisdiction for Certain Actions**

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

89 <br>

**Section 203 of the Delaware General Corporation Law**

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· before
 the stockholder became interested, our Board of Directors approved either the business combination
 or the transaction which resulted in the stockholder becoming an interested stockholder;

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

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

Section 203 defines a business combination to include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· any
 merger or consolidation involving the corporation and the interested stockholder;

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

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

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

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

In general, Section 203 defines an interested stockholder as any entity or person beneficially owning 15% or more of the outstanding voting stock of the corporation and any entity or person affiliated with or controlling or controlled by the entity or person.

**PLAN OF DISTRIBUTION**

We have engaged H.C. Wainwright & Co., LLC, or the placement agent, to act as our exclusive placement agent to solicit offers to purchase the shares of our common stock, pre-funded warrants and common warrants offered by this prospectus. The placement agent is not purchasing or selling any such securities, nor is it required to arrange for the purchase and sale of any specific number or dollar amount of such securities, other than to use its "reasonable best efforts" to arrange for the sale of such securities by us. Therefore, we may not sell all of the shares of common stock, pre-funded warrants and common warrants being offered. The terms of this offering were subject to market conditions and negotiations between us, the placement agent and prospective investors. The placement agent will have no authority to bind us by virtue of the engagement letter. This is a best efforts offering and there is no minimum offering amount required as a condition to the closing of this offering. The placement agent may retain sub-agents and selected dealers in connection with this offering. Investors purchasing securities offered hereby will have the option to execute a securities purchase agreement with us. In addition to rights and remedies available to all purchasers in this offering under federal securities and state law, the purchasers which enter into a securities purchase agreement will also be able to bring claims of breach of contract against us. The ability to pursue a claim for breach of contract is material to larger purchasers in this offering as a means to enforce the following covenants uniquely available to them under the securities purchase agreement: (i) a covenant to not enter into variable rate financings for a period of one year following the closing of the offering, subject to an exception; and (ii) a covenant to not enter into any equity financings for 60 days from closing of the offering, subject to certain exceptions.

The nature of the representations, warranties and covenants in the securities purchase agreements shall include:

&nbsp;&nbsp;&nbsp;&nbsp;· standard
 issuer representations and warranties on matters such as organization, qualification, authorization,
 no conflict, no governmental filings required, current in SEC filings, no litigation, labor
 or other compliance issues, environmental, intellectual property and title matters and compliance
 with various laws such as the Foreign Corrupt Practices Act; and

&nbsp;&nbsp;&nbsp;&nbsp;· covenants
 regarding matters such as registration of warrant shares, no integration with other offerings,
 filing of an 8-K to disclose entering into these securities purchase agreements, no shareholder
 rights plans, no material nonpublic information, use of proceeds, indemnification of purchasers,
 reservation and listing of common stock, and no subsequent equity sales for 60 days.

Delivery of the shares of common shares, pre-funded warrants and common warrants offered hereby is expected to occur on or about January 11, 2023, subject to satisfaction of certain customary closing conditions.

We have agreed to pay the placement agent an aggregate fee equal to $450,000.02. In addition, we have agreed to reimburse the placement agent for its legal fees and expenses and other out-of-pocket expenses in an amount up to $60,000 and clearing expenses of $15,950.

We estimate the total expenses of this offering paid or payable by us, exclusive of the placement agent's cash fee of 6% of the gross proceeds and expenses, will be approximately $0.3 million. After deducting the fees due to the placement agent and our estimated expenses in connection with this offering, we expect the net proceeds from this offering will be approximately $6.8 million.

The following table shows the per share and total cash fees we will pay to the placement agent in connection with the sale of the common stock and shares of common stock underlying the pre-funded warrants pursuant to this prospectus.

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | **Per Share and Common Warrants** | **Per Pre-Funded Warrant and Common Warrant** | **Total** |  |
| Public offering price | $2.90 | $2.89 | $7500000.30 | (1) |
| Placement agent fees | $0.174 | $0.174 | $450000.02 |  |
| Proceeds, before expenses, to OpGen, Inc. | $2.726 | $2.716 | $7050000.28 |  |

---

&nbsp;&nbsp;&nbsp;&nbsp;(1) The total public offering price assumes the full exercise of the pre-funded warrants issued in the offering.

**Indemnification**

We have agreed to indemnify the placement agent against certain liabilities, including liabilities under the Securities Act and liabilities arising from breaches of representations and warranties contained in our engagement letter with the placement agent. We have also agreed to contribute to payments the placement agent may be required to make in respect of such liabilities.

**Lock-up Agreements**

We and each of our officers and directors have agreed with the placement agent to be subject to a lock-up period of 60 days following the date of closing of the offering pursuant to this prospectus. This means that, during the applicable lock-up period, we and such persons may not offer for sale, contract to sell, sell, distribute, grant any option, right or warrant to purchase, pledge, hypothecate or otherwise dispose of, directly or indirectly, any of our shares of common stock or any securities convertible into, or exercisable or exchangeable for, shares of common stock, subject to customary exceptions. The placement agent may waive the terms of these lock-up agreements in its sole discretion and without notice. In addition, we have agreed to not issue any securities that are subject to a price reset based on the trading prices of our common stock or upon a specified or contingent event in the future or enter into any agreement to issue securities at a future determined price for a period of one year following the closing date of this offering, subject to an exception. The placement agent may waive this prohibition in its sole discretion and without notice.

91 <br>

**Other Relationships**

From time to time, the placement agent may provide in the future various advisory, investment and commercial banking and other services to us in the ordinary course of business, for which they have received and may continue to receive customary fees and commissions. However, except as disclosed in this prospectus, we have no present arrangements with the placement agent for any further services. The placement agent is currently acting as sales agent under our existing At the Market, or ATM, Offering, which commenced in June 2022, for which it receives compensation.

**Regulation M Compliance**

The placement agent may be deemed to be an underwriter within the meaning of Section 2(a)(11) of the Securities Act, and any commissions received by it and any profit realized on the sale of our securities offered hereby by it while acting as principal might be deemed to be underwriting discounts or commissions under the Securities Act. The placement agent will be required to comply with the requirements of the Securities Act and the Exchange Act, including, without limitation, Rule 10b-5 and Regulation M under the Exchange Act. These rules and regulations may limit the timing of purchases and sales of our securities by the placement agent. Under these rules and regulations, the placement agent may not (i) engage in any stabilization activity in connection with our securities; and (ii) bid for or purchase any of our securities or attempt to induce any person to purchase any of our securities, other than as permitted under the Exchange Act, until they have completed their participation in the distribution.

**Trading Market**

Our common stock is listed on the Nasdaq Capital Market under the symbol "OPGN." There is no established public trading market for the pre-funded warrants or common warrants to be sold in this offering, and we do not expect a market to develop. In addition, we do not intend to apply for listing of the common warrants or pre-funded warrants on any national securities exchange.

92 <br>

**MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES**

The following is a summary of the material U.S. federal income tax consequences of the acquisition, ownership and disposition of our common stock and pre-funded warrants, but does not purport to be a complete analysis of all the potential tax considerations relating thereto. Throughout this summary, all references to our common stock are meant to include our pre-funded warrants. This summary is based upon the provisions of the Internal Revenue Code of 1986, as amended, or the Code, Treasury Regulations promulgated thereunder, administrative rulings and judicial decisions, all as of the date hereof. These authorities may be changed or subject to differing interpretations, possibly with retroactive effect, with the resulting U.S. federal income tax consequences being different from those set forth below. We have not sought and will not seek any ruling from the Internal Revenue Service, or the IRS, with respect to the statements made and the conclusions reached in the following summary, and there can be no assurance that the IRS or a court will agree with such statements and conclusions.

This summary also does not address the tax considerations arising under the laws of any U.S. state or local or any non-U.S. jurisdiction, estate or gift tax, the 3.8% Medicare tax on net investment income or any alternative minimum tax consequences. In addition, this discussion does not address tax considerations applicable to a holder's particular circumstances or to a holder that may be subject to special tax rules, including, without limitation:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· banks,
 insurance companies or other financial institutions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· tax-exempt
 or government organizations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· brokers
 or dealers in securities or currencies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· traders
 in securities that elect to use a mark-to-market method of accounting for their securities
 holdings;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· persons
 that own, or are deemed to own, more than 5.0% of our capital stock;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· certain
 U.S. expatriates, citizens or former long-term residents of the United States;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· persons
 who hold our common stock as a position in a hedging transaction, "straddle,"
 "conversion transaction," synthetic security, other integrated investment, or
 other risk reduction transaction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· persons
 who do not hold our common stock as a capital asset within the meaning of Section 1221 of
 the Code (generally, for investment purposes);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· persons
 deemed to sell our common stock under the constructive sale provisions of the Code;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· pension
 plans;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· partnerships,
 or other entities or arrangements treated as partnerships for U.S. federal income tax purposes,
 or investors in any such entities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· persons
 for whom our stock constitutes "qualified small business stock" within the meaning
 of Section 1202 of the Code;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· integral
 parts or controlled entities of foreign sovereigns;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· passive
 foreign investment companies and corporations that accumulate earnings to avoid U.S. federal
 income tax; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· persons
 that acquire our common stock as compensation for services.

93 <br>

In addition, if a partnership, including any entity or arrangement classified as a partnership for U.S. federal income tax purposes, holds our common stock, the tax treatment of a partner generally will depend on the status of the partner, the activities of the partnership, and certain determinations made at the partner level. Accordingly, partnerships that hold our common stock, and partners in such partnerships, should consult their tax advisors regarding the U.S. federal income tax consequences to them of the purchase, ownership, and disposition of our common stock.

You are urged to consult your tax advisor with respect to the application of the U.S. federal income tax laws to your particular situation, as well as any tax consequences of the purchase, ownership and disposition of our common stock arising under the U.S. federal estate or gift tax rules or under the laws of any U.S. state or local or any non-U.S. or other taxing jurisdiction or under any applicable tax treaty.

**Definition of a U.S. Holder**

For purposes of this summary, a "U.S. Holder" is any beneficial owner of our common stock that is a "U.S. person," and is not a partnership, or an entity treated as a partnership or disregarded from its owner, each for U.S. federal income tax purposes. A U.S. person is any person that, for U.S. federal income tax purposes, is or is treated as any of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· an
 individual who is a citizen or resident of the United States;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· a
 corporation created or organized under the laws of the United States, any state thereof,
 or the District of Columbia;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· an
 estate, the income of which is subject to U.S. federal income tax regardless of its source;
 or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· a
 trust that (1) is subject to the primary supervision of a U.S. court and the control of one
 or more U.S. persons (within the meaning of Section 7701(a)(30) of the Code), or (2) has
 a valid election in effect to be treated as a U.S. person for U.S. federal income tax purposes.

For purposes of this summary, a "Non-U.S. Holder" is any beneficial owner of our common stock that is not a U.S. Holder or a partnership, or other entity treated as a partnership or disregarded from its owner, each for U.S. federal income tax purposes.

**Tax Consequences to U.S. Holders**

**Distributions on Common Stock**

As discussed above under "Dividend Policy," we do not currently expect to make distributions on our common stock. In the event that we do make distributions of cash or other property, distributions paid on common stock, other than certain pro rata distributions of common stock, will be treated as a dividend to the extent paid out of our current or accumulated earnings and profits, if any, and will be includible in income by the U.S. Holder and taxable as ordinary income when received. If a distribution exceeds our current and accumulated earnings and profits, the excess will be first treated as a tax-free return of the U.S. Holder's investment, up to the U.S. Holder's tax basis in the common stock. Any remaining excess will be treated as a capital gain. Subject to applicable limitations, dividends paid to certain non-corporate U.S. Holders may be eligible for taxation as "qualified dividend income" and therefore may be taxable at rates applicable to long-term capital gains. U.S. Holders should consult their tax advisers regarding the availability of the reduced tax rate on dividends in their particular circumstances. Dividends received by a corporate U.S. Holder will be eligible for the dividends-received deduction if the U.S. Holder meets certain holding period and other applicable requirements.

**Sale or Other Disposition of Common Stock**

For U.S. federal income tax purposes, gain or loss realized on the sale or other disposition of common stock will be capital gain or loss, and will be long-term capital gain or loss if the U.S. Holder held the common stock for more than one year. The amount of the gain or loss will equal the difference between the U.S. Holder's tax basis in the common stock disposed of and the amount realized on the disposition. Long-term capital gains recognized by non-corporate U.S. Holders will be subject to reduced tax rates. The deductibility of capital losses is subject to limitations.

94 <br>

**Treatment of Pre-Funded Warrants**

Although it is not entirely free from doubt, we believe a pre-funded warrant should be treated as common stock for U.S. federal income tax purposes and a holder of pre-funded warrants should generally be taxed in the same manner as a holder of our common stock, as described below. Accordingly, no gain or loss should be recognized upon the exercise of a pre-funded warrant and, upon exercise, the holding period of a pre-funded warrant should carry over to the common stock received. Similarly, the tax basis of the pre-funded warrant should carry over to the common stock received upon exercise, increased by the exercise price of $0.01 per share**.** However, our characterization of a pre-funded warrant is not binding on the IRS, and the IRS may treat our pre-funded warrants as warrants to acquire our common stock. If so, the amount and character of your gain with respect to an investment in our pre-funded warrants could change. Accordingly, each holder should consult his, her or its own tax advisor regarding the risks associated with the acquisition of pre-funded warrants pursuant to this offering (including potential alternative characterizations). The balance of this discussion generally assumes that our characterization described above is respected for U.S. federal income tax purposes.

**Tax Consequences to Non-U.S. Holders**

**Distributions**

As discussed in the section entitled "Dividend Policy," we do not anticipate paying any dividends on our common stock in the foreseeable future. If we make distributions on our common, those payments will constitute dividends for U.S. federal income tax purposes to the extent we have current or accumulated earnings and profits, as determined under U.S. federal income tax principles. To the extent those distributions exceed both our current and our accumulated earnings and profits, they will constitute a return of capital and will first reduce a Non-U.S. Holder's basis in our common stock, as applicable, but not below zero. Any excess will be treated as capital gain and will be treated as described below under the "—Gain on Sale or Other Disposition of Common Stock" section. Any such distributions would be subject to the discussions below regarding back-up withholding and the Foreign Account Tax Compliance Act, or FATCA.

Subject to the discussion below on effectively connected income, any dividend paid to a Non-U.S. Holder generally will be subject to U.S. withholding tax either at a rate of 30% of the gross amount of the dividend or such lower rate as may be specified by an applicable income tax treaty. To receive a reduced treaty rate, a Non-U.S. Holder must provide us or our agent with an IRS Form W-8BEN (generally including a U.S. taxpayer identification number), IRS Form W-8 BEN-E or another appropriate version of IRS Form W-8 (or a successor form), which must be updated periodically, and which, in each case, must certify qualification for the reduced treaty rate. Non-U.S. Holders should consult their tax advisors regarding their entitlement to benefits under any applicable income tax treaty.

Dividends paid to a Non-U.S. Holder that are effectively connected with the Non-U.S. Holder's conduct of a trade or business within the United States and that are not eligible for relief from U.S. (net basis) income tax under an applicable income tax treaty, generally are exempt from the (gross basis) withholding tax described above. To obtain this exemption from withholding tax, the Non-U.S. Holder must provide the applicable withholding agent with an IRS Form W-8ECI or successor form or other applicable IRS Form W-8 certifying that the dividends are effectively connected with the Non-U.S. Holder's conduct of a trade or business within the United States. Such effectively connected dividends, if not eligible for relief under a tax treaty, would not be subject to a withholding tax, but would be taxed at the same graduated rates applicable to U.S. persons, net of certain deductions and credits and if, in addition, the Non-U.S. Holder is a corporation, may also be subject to a branch profits tax at a rate of 30% (or such lower rate as may be specified by an applicable income tax treaty).

If you are eligible for a reduced rate of withholding tax pursuant to a tax treaty, you may be able to obtain a refund of any excess amounts withheld if you timely file an appropriate claim for refund with the IRS.

95 <br>

**Gain on Sale or Other Disposition of Common Stock**

Subject to the discussion below regarding backup withholding and FATCA, a Non-U.S. Holder generally will not be required to pay U.S. federal income tax on any gain realized upon the sale or other disposition of our common stock unless:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the
 gain is effectively connected with the Non-U.S. Holder's conduct of a trade or business
 within the United States and not eligible for relief under an applicable income tax treaty,
 in which case the Non-U.S. Holder will be required to pay tax on the net gain derived from
 the sale under regular graduated U.S. federal income tax rates, and for a Non-U.S. Holder
 that is a corporation, such Non-U.S. Holder may be subject to the branch profits tax at a
 30% rate (or such lower rate as may be specified by an applicable income tax treaty) on such
 effectively connected gain, as adjusted for certain items;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the
 Non-U.S. Holder is an individual who is present in the United States for a period or periods
 aggregating 183 days or more during the calendar year in which the sale or disposition occurs
 and certain other conditions are met, in which case the Non-U.S. Holder will be required
 to pay a flat 30% tax on the gain derived from the sale, which tax may be offset by U.S.
 source capital losses (even though the Non-U.S. Holder is not considered a resident of the
 United States) (subject to applicable income tax or other treaties); or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· we
 are a "U.S. real property holding corporation" for U.S. federal income tax purposes,
 or a USRPHC, at any time within the shorter of the five-year period preceding the disposition
 or the Non-U.S. Holder's holding period for our common stock. We believe we are not
 currently and do not anticipate becoming a USRPHC. However, because the determination of
 whether we are a USRPHC depends on the fair market value of our United States real property
 interests relative to the fair market value of our other business assets, there can be no
 assurance that we will not become a USRPHC in the future. Even if we become a USRPHC, however,
 gain arising from the sale or other taxable disposition by a Non-U.S. Holder of our common
 stock will not be subject to United States federal income tax if (a) shares of our common
 stock are "regularly traded," as defined by applicable Treasury Regulations,
 on an established securities market, such as Nasdaq, and (b) the Non-U.S. Holder owns or
 owned, actually and constructively, 5% or less of the shares of our common stock throughout
 the five-year period ending on the date of the sale or exchange. If the foregoing exception
 does not apply, such Non-U.S. Holder's proceeds received on the disposition of shares
 will generally be subject to withholding at a rate of 15% and such Non-U.S. Holder will generally
 be taxed on any gain in the same manner as gain that is effectively connected with the conduct
 of a U.S. trade or business, except that the branch profits tax generally will not apply.

**Information Reporting and Backup Withholding**

Information returns may be filed with the IRS in connection with distributions on common, and the proceeds of a sale or other disposition of common stock. A non-exempt U.S. Holder may be subject to U.S. backup withholding on these payments if it fails to provide its taxpayer identification number to the withholding agent and comply with certification procedures or otherwise establish an exemption from backup withholding.

A Non-U.S. Holder may be subject to U.S. information reporting and backup withholding on these payments unless the Non-U.S. Holder complies with certification procedures to establish that it is not a U.S. person (within the meaning of the Code). The certification requirements generally will be satisfied if the Non-U.S. Holder provides the applicable withholding agent with a statement on the applicable IRS Form (or a suitable substitute or successor form), together with all appropriate attachments, signed under penalties of perjury, stating, among other things, that such Non-U.S. Holder is not a U.S. Person. Applicable Treasury Regulations provide alternative methods for satisfying this requirement. In addition, the amount of distributions on common stock paid to a Non-U.S. Holder, and the amount of any U.S. federal tax withheld therefrom, must be reported annually to the IRS and the holder. This information may be made available by the IRS under the provisions of an applicable tax treaty or agreement to the tax authorities of the country in which the Non-U.S. Holder resides.

Payment of the proceeds of the sale or other disposition of common stock to or through a non-U.S. office of a U.S. broker or of a non-U.S. broker with certain specified U.S. connections generally will be subject to information reporting requirements, but not backup withholding, unless the Non-U.S. Holder certifies under penalties of perjury that it is not a U.S. person or an exemption otherwise applies. Payments of the proceeds of a sale or other disposition of common stock to or through a U.S. office of a broker generally will be subject to information reporting and backup withholding, unless the Non-U.S. Holder certifies under penalties of perjury that it is not a U.S. person or otherwise establishes an exemption.

Backup withholding is not an additional tax. The amount of any backup withholding from a payment generally will be allowed as a credit against the holder's U.S. federal income tax liability and may entitle the holder to a refund, provided that the required information is timely furnished to the IRS.

**Foreign Accounts**

The Code generally imposes a U.S. federal withholding tax of 30% on dividends and, subject to the discussion below regarding proposed regulations recently issued by the U.S. Treasury Department, the gross proceeds of a disposition of our securities paid to a "foreign financial institution" (as specifically defined for this purpose), unless such institution enters into an agreement with the U.S. government to, among other things, withhold on certain payments and to collect and provide to the U.S. tax authorities substantial information regarding U.S. account holders of such institution (which includes certain equity and debt holders of such institution, as well as certain account holders that are foreign entities with U.S. owners) or otherwise qualifies for an exemption from these rules. A U.S. federal withholding tax of 30% also applies to dividends and, subject to the discussion below regarding proposed regulations recently issued by the U.S. Treasury Department, will apply to the gross proceeds of a disposition of our securities paid to a non-financial foreign entity (as defined in the Code), unless such entity provides the withholding agent with either a certification that it does not have any substantial direct or indirect. "United States owners" (as defined in the Code), provides information regarding each substantial United States owners of the entity, or otherwise qualifies for an exemption from these rules.

Under certain circumstances, a non-U.S. holder might be eligible for refunds or credits of such taxes. An intergovernmental agreement between the United States and an applicable foreign country may modify the requirements described in this paragraph.

The U.S. Treasury Department released proposed regulations which, if finalized in their present form, would eliminate the federal withholding tax of 30% applicable to the gross proceeds of a sale or other disposition of our common stock. In its preamble to such proposed regulations, the U.S. Treasury Department stated that taxpayers may generally rely on the proposed regulations until final regulations are issued. Prospective investors should consult their own tax advisors regarding the possible impact of these rules on their investment in our common stock, and the possible impact of these rules and the proposed regulations on the entities through which they hold our common stock, including, without limitation, the process and deadlines for meeting the applicable requirements to prevent the imposition of this 30% withholding tax.

EACH PROSPECTIVE INVESTOR SHOULD CONSULT ITS TAX ADVISOR REGARDING THE PARTICULAR U.S. FEDERAL, STATE AND LOCAL AND NON-U.S. TAX CONSEQUENCES OF PURCHASING, HOLDING AND DISPOSING OF OUR SECURITIES, INCLUDING THE CONSEQUENCES OF ANY PROPOSED CHANGE IN APPLICABLE LAWS. IN ADDITION, SIGNIFICANT CHANGES IN U.S. FEDERAL TAX LAWS WERE RECENTLY ENACTED. PROSPECTIVE INVESTORS SHOULD ALSO CONSULT WITH THEIR TAX ADVISORS WITH RESPECT TO SUCH CHANGES IN U.S. TAX LAW AS WELL AS POTENTIAL CONFORMING CHANGES IN STATE TAX LAWS.

**EXPERTS**

The consolidated financial statements of OpGen, Inc. and its subsidiaries as of December 31, 2021 and 2020, and for the years then ended, have been incorporated by reference herein in reliance upon the report, also incorporated by reference herein, of CohnReznick LLP, an independent registered public accounting firm, and upon the authority of said firm as experts in accounting and auditing. The audit report covering the December 31, 2021 consolidated financial statements contains an explanatory paragraph that states that the Company has experienced losses and negative cash flows from operations since its inception, has an accumulated deficit, and has debt obligations coming due which collectively raise substantial doubt about its ability to continue as a going concern. The consolidated financial statements do not include any adjustments that might result from the outcome of that uncertainty.
