Fair value measurements

Fair Value Disclosures [Abstract]

Fair value measurements

Note 5 – Fair value measurements

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

●

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

●

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

●

Level 3 - defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions such as expected revenue growth and discount factors applied to cash flow projections.

For the three and six months ended June 30, 2024, the Company has not transferred any assets between fair value measurement levels.

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

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

In 2016, Curetis entered into a contract for an up to €25.0 million senior, unsecured loan financing facility from the EIB (see Note 6). In June 2019, Curetis drew down a third tranche of €5.0 million from the EIB. In return for the EIB waiving the condition precedent of a minimum cumulative equity capital raised of €15.0 million to disburse this €5.0 million tranche, the parties agreed on a 2.1% participation percentage interest (“PPI”). Upon maturity of the tranche, the EIB would be entitled to an additional payment that is equity-linked and equivalent to 2.1% of the then total valuation of Curetis N.V. On July 9, 2020, the Company negotiated an amendment to the EIB debt financing facility. As part of the amendment, the parties adjusted the PPI percentage applicable to the previous EIB tranche of €5.0 million which was funded in June 2019 from its original 2.1% PPI in Curetis N.V.’s equity value upon maturity to a new 0.3% PPI in OpGen’s equity. On May 23, 2022, the Company entered into a Waiver and Amendment Letter which increased the PPI to 0.75% upon maturity. This right constituted an embedded derivative, which is separated and measured at fair value with changes being accounted for through profit or loss. The Company determines the fair value of the derivative using a Monte Carlo simulation model. Using this model, level 3 unobservable inputs include estimated discount rates and estimated risk-free interest rates.

Following Curetis’ insolvency filing, on November 20, 2023, Curetis received a termination notice from the EIB terminating the Standstill Agreement effective as of November 20, 2023. On December 4, 2023, the Company received a notice from the EIB stating that Curetis is in default of the Finance Contract as a result of, among other things, Curetis’ failure to repay when due certain outstanding indebtedness under the Finance Contract. Pursuant to that certain Guarantee and Indemnity Agreement, dated July 9, 2020, between the EIB and the Company, the EIB demanded that the Company, as guarantor, immediately repay the EIB all amounts owed to the EIB under the Finance Contract and reserved all its other rights and remedies in connection with the Finance Contract. The Company determined the fair value of the PPI using the Monte Carlo simulation model as of June 30, 2024. Upon deconsolidation of the Company’s subsidiaries in 2023, the Company reclassified the EIB liability from a loan to a loan guaranty which is recorded based on its fair value with changes being recognized as part of net income at each reporting date. As a result, the Company included the PPI component along with the principal and interest in the EIB loan guaranty as of June 30, 2024.

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

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

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

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

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

The Company measures its long-lived assets, including property and equipment and intangible assets (including goodwill), at fair value on a non-recurring basis when a triggering event requires such evaluation. During the year ended December 31, 2023, the Company recorded impairment expense of $1,231,874 related to its property and equipment (see Note 3) and $849,243 related to its operating lease right-of-use asset (see Note 3). In the Company’s Amended Form 10-Q for the three months ended March 31, 2024, the Company recorded a change in accounting estimate on the Company’s leasehold improvement property and equipment and operating lease right-of-use asset, bringing the balances as of the beginning of the period back to $1,230,332 and $849,243, respectively, following the Company’s identification of a subtenant (see Note 3). During the three and six months ended June 30, 2024, the Company did not record any such impairment expenses.

Equity [Abstract]

Stockholders’ equity

Note 7 – Stockholders’ equity

As of June 30, 2024, the Company had 100,000,000 shares of authorized common stock and 1,348,974 shares issued and outstanding, and 10,000,000 shares of authorized preferred stock, of which 6,999,000 shares remain undesignated and unissued.

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

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

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

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

On October 11, 2023, the Company entered into a Preferred Stock Purchase Agreement (the “Purchase Agreement”) with a single investor (the “Investor”), pursuant to which the Company agreed to issue and sell to the Investor in a private placement (the “Private Placement”) 1,000 shares of the Company’s Series D Preferred Stock, par value $0.01 per share (the “Preferred Stock”). Each share of preferred stock was agreed to sell at a price of $1,000 per share for expected aggregate gross proceeds of $1.0 million before deducting offering expenses. The Private Placement was conducted in connection with the negotiation of a potential strategic transaction involving the Company and the Investor. The Company intended to use the proceeds of the Private Placement to fund the Company’s operations while it pursued a potential strategic transaction with the Investor. Pursuant to the Purchase Agreement, the Company filed a certificate of designation (the “Certificate of Designation”) with the Secretary of State of the State of Delaware designating the rights, preferences and limitations of the shares of preferred stock on October 11, 2023. The Certificate of Designation provides that the shares of preferred stock have a stated value of $1,000 per share and are convertible into shares of common stock, par value $0.01 per share of the Company at a price of $4.09 per share, subject to adjustment in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications, or similar events affecting the common stock. The preferred stock may be converted at any time at the option of the holder. Notwithstanding the foregoing, the Certificate of Designation provides that in no event will the preferred stock be convertible into common stock in a manner that would result in the holder, its permitted transferees and affiliates holding more than 19.99% (together with any shares of common stock otherwise held by the Investor, its permitted transferees and their affiliates) of the then issued and outstanding common stock (the “Ownership Limitation”), prior to the date that the Company’s stockholders approve the issuance of shares of common stock to the holder upon conversion of the preferred stock (the “stockholder approval”). Upon receipt of stockholder approval, the shares of preferred stock will automatically be converted into shares of common stock without further action of the holder thereof. The Investor funded $250,000 of the expected aggregate gross proceeds of $1.0 million before deducting offering expenses on November 14, 2023. On December 13, 2023, in coordination with the Investor, the Company issued to the Investor 250 shares of Series D Preferred Stock in consideration for the partial payment. As of June 30, 2024, all 250 Series D Preferred Shares remain outstanding and the remaining $750,000 of the purchase price remains unpaid. The Company reserves all rights and remedies arising from the Investor’s failure to close the transaction and the Investor will continue to be in breach of the Purchase Agreement until the remaining amount is paid in full.

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

On March 25, 2024, the Company entered into a securities purchase agreement (the “March 2024 Purchase Agreement”) with David E. Lazar, pursuant to which the Company agreed to sell 3,000,000 shares of Series E Convertible Preferred Stock (“Series E Preferred Stock”) to Mr. Lazar at a price of $1.00 per share for aggregate gross proceeds of $3.0 million. In connection with the transactions contemplated by the March 2024 Purchase Agreement, the members of the Board of Directors, prior to the closing of such transactions, resigned and a new Board of Directors was appointed, of which Mr. Lazar was appointed Chairman. On March 25, 2024, Mr. Lazar paid $200,000 at the initial closing of the transactions under the March 2024 Purchase Agreement in exchange for 200,000 shares of Series E Preferred Stock. Mr. Lazar subsequently paid $200,000 and $150,000 on April 5, 2024 and April 23, 2024, respectively, in exchange for an additional 350,000 shares of Series E Preferred Stock. Each share of Series E Preferred Stock is convertible into 2.4 shares of the Company’s common stock (“Common Stock”), and following stockholder approval of the issuance of shares of Common Stock to Mr. Lazar upon conversion of the Series E Preferred Stock at the Company’s special meeting of stockholders held on May 9, 2024, Mr. Lazar or his transferees or their affiliates may convert the Series E Preferred Stock into Common Stock and hold in excess of applicable beneficial ownership limitations. In connection with the transactions contemplated by the March 2024 Purchase Agreement, the Company entered into settlement agreements (the “Settlement Agreements”) with each of the European Investment Bank (“EIB”) and Curetis GmbH, the Company’s subsidiary (“Curetis”), and Curetis’ trustee in insolvency, pursuant to which the Company will settle outstanding liabilities amongst the parties. Pursuant to the settlement agreements and the March 2024 Purchase Agreement, following the final closing of transactions contemplated by the March 2024 Purchase Agreement, the Company will pay a total of $2.0 million of the proceeds to settle all outstanding debt of the Company to EIB and Curetis. The settlement agreement with EIB will also terminate that certain Guarantee and Indemnity Agreement, dated as of July 9, 2020, by and between the EIB and the Company, pursuant to which the Company had guaranteed all of Curetis’ debt to EIB. As a result of delays to the final closing of the Private Placement, the settlement amounts remain unpaid; however, the Company and the EIB are in ongoing discussions regarding an amendment to such settlement agreements to cure such delays, which the Company anticipates resolving in the third quarter of 2024. Upon termination of the Guarantee and Indemnity Agreement, the Company anticipates recording a gain on extinguishment of debt in excess of $8 million. On July 31, 2024, Mr. Lazar consummated a transaction pursuant to which he sold 550,000 shares of Series E Preferred Stock together with his rights to purchase the additional 2,450,000 shares of Series E Preferred Stock under the March 2024 Purchase Agreement to AEI Capital Ltd. AEI Capital Ltd. funded the remaining $2.45 million in August 2024, and it has since received the remaining 2.45 million shares of Series E Preferred Stock (see Note 11).

Stock options

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

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

Under the 2015 Plan, the aggregate number of shares of the common stock authorized for issuance may not exceed (1) 271 plus (2) the sum of the number of shares subject to outstanding awards under the 2008 Plan as of the 2015 Plan’s effective date, that are subsequently forfeited or terminated for any reason before being exercised or settled, plus (3) the number of shares subject to vesting restrictions under the 2008 Plan as of the 2015 Plan’s effective date that are subsequently forfeited. In addition, the number of shares that have been authorized for issuance under the 2015 Plan will be automatically increased on the first day of each fiscal year beginning on January 1, 2016 and ending on (and including) January 1, 2025, in an amount equal to the lesser of (1) 4% of the outstanding shares of common stock on the last day of the immediately preceding fiscal year, or (2) another lesser amount determined by the Company’s Board of Directors. Following Board of Director approval, 48,058 shares were automatically added to the 2015 Plan in 2024. Shares subject to awards granted under the 2015 Plan that are forfeited or terminated before being exercised or settled, or are not delivered to the participant because such award is settled in cash, will again become available for issuance under the 2015 Plan. However, shares that have actually been issued shall not again become available unless forfeited. As of June 30, 2024, 6,693 shares remain available for issuance under the 2015 Plan.

For the three and six months ended June 30, 2024 and 2023, the Company recognized share-based compensation expense as follows:

License agreements, research collaborations and development agreements

License Agreements Research Collaborations And Development Agreements

License agreements, research collaborations and development agreements

Note 10 – License agreements, research collaborations and development agreements

Sandoz

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

Under the terms of the framework agreement, which had an initial term of 36 months and was subsequently extended to January 31, 2025, Ares Genetics and Sandoz intended to develop a digital anti-infectives platform, combining established microbiology laboratory methods with advanced bioinformatics and artificial intelligence methods to support drug development and life-cycle management. The collaboration, in the short- to mid-term, aimed to both rapidly and cost-effectively re-purpose existing antibiotics and design value-added medicines with the objective of expanding indication areas and to overcome antibiotic resistance, in particular with regards to infections with bacteria that have already developed resistance against multiple treatment options. In the longer-term, the platform was expected to enable surveillance for antimicrobial resistant pathogens to inform antimicrobial stewardship and the development of novel anti-infectives that are less prone to encounter resistance and thereby preserve antibiotics as an effective treatment option. Following Ares Genetics’ insolvency filing in 2023, the Company will no longer benefit from this framework agreement.

Qiagen

On February 18, 2019, Ares Genetics and Qiagen GmbH, or Qiagen, entered into a strategic licensing agreement for ARESdb and AREStools, in the area of AMR research. The agreement had a term of 20 years and could have been terminated by Qiagen for convenience with 180 days written notice.

Under the terms of the original agreement, Qiagen, in exchange for a moderate six figure up-front licensing payment, received an exclusive RUO license to develop and commercialize general bioinformatics offerings and services for AMR research use only, based on Ares Genetics’ database on the genetics of antimicrobial resistance, ARESdb, as well as on the ARES bioinformatics AMR toolbox, AREStools. Under the agreement, the parties had agreed to a mid-single digit percentage royalty rate on Qiagen net sales, which is subject to a minimum royalty rate that steps up upon certain achieved milestones, which is payable to Ares Genetics. The parties also agreed to further modest six figure milestone payments upon certain product launches. The contract was subsequently amended in May 2021 to a non-exclusive license and a flat annual license fee as well as a royalty percentage on potential future panel-based products that are developed by Qiagen. Following the insolvency filings of Curetis and Ares Genetics in 2023, the Company will no longer benefit from this strategic licensing agreement.

Siemens

In 2016, Ares Genetics acquired the GEAR assets from Siemens Technology Accelerator GmbH (“STA”), providing the original foundation to ARESdb. Under the agreement with STA, Ares Genetics incurred royalties on revenues from licensed product sales or sublicensing proceeds. Royalty rates under the Siemens agreement ranged from 1.3% to 40% depending on the specifics of the licenses and rights provided by Ares Genetics to third parties and whether such third parties may have been originally introduced by Siemens to Ares Genetics. The total net royalty expense related to this agreement was $0 and $2,264 for the three months ended June 30, 2024 and 2023, respectively. The total net royalty expense related to this agreement was $0 and $4,207 for the six months ended June 30, 2024 and 2023, respectively. Following Ares Genetics’ insolvency filing in 2023, the Company will no longer generate licensed product sales or sublicense revenues nor incur royalty expenses related to the Siemens GEAR assets.

Foundation for Innovative New Diagnostics (FIND)

On September 20, 2022, Curetis GmbH and FIND entered into a research and development collaboration agreement for €0.7 million to develop a simple to use molecular diagnostic test for identification of pathogens and antibiotic resistances in positive blood cultures for deployment in low- and middle-income countries (“LMICs”). On April 4, 2023, the Company entered into an amendment to its research and development collaboration agreement with FIND to expand the deliverables in exchange for an additional €0.13 million in milestone payments (“Amendment 1”). The additional deliverables were completed by June 30, 2023. Following successful completion of the feasibility phase of the collaboration, including the additional deliverables, FIND and Curetis, on August 1, 2023, extended the research and development collaboration agreement through May 31, 2024, to include AMR assay and cartridge development, analytical testing, and software development for an additional €0.5 million (“Amendment 2”). The Company did not recognize any revenues related to the FIND collaboration during the three and six months ended June 30, 2024. The agreement-to-date revenue recognized by the Company related to the FIND collaboration was $0.9 million. Following Curetis’ insolvency filing in 2023, the Company will no longer benefit from this collaboration agreement.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Going Concern and Management’s Plans

Note 2 – Going Concern and Management’s Plans

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

●

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

●

On June 26, 2023, the Company announced that its subsidiary Curetis and the European Investment Bank (“EIB”) agreed in principle to certain terms relating to the repayment of the second tranche of Curetis’ loan from the EIB pursuant to that certain Finance Contract, dated December 12, 2016, as amended, by and between Curetis and the EIB (the “Finance Contract”). The second tranche had a principal balance of €3 million plus accumulated and deferred interest. The second tranche was drawn down in June 2018 and matured on June 22, 2023. On July 4, 2023, the EIB and Curetis entered into a Standstill Agreement (the “Standstill Agreement”) pursuant to which the EIB agreed that, with respect to each default or event of default relating to such second tranche, the EIB would not take any action or exercise any right under the Finance Contract until the earlier of a restructuring of the second tranche and November 30, 2023. As a condition to entering into the Standstill Agreement, Curetis paid the EIB a partial payment of interest on the second tranche of €1 million on June 22, 2023. In addition, Curetis agreed to certain undertakings during the standstill period, including the delivery of a rolling cash flow forecast and to cause a third-party restructuring expert to prepare and deliver a restructuring opinion to the EIB. On November 20, 2023, Curetis received a termination notice from the EIB terminating the Standstill Agreement effective as of November 20, 2023. The EIB’s termination notice stated that the termination of the Standstill Agreement was as a result of and in connection with certain defaults of the Standstill Agreement arising from, among other related reasons, Curetis’ and Ares’ entry into insolvency proceedings. On December 4, 2023, the Company received a notice from the EIB stating that Curetis is in default of the Finance Contract as a result of, among other things, Curetis’ failure to repay when due certain outstanding indebtedness under the Finance Contract. In its notice, the EIB stated that, as of November 16, 2023, the aggregate amount of principal, accrued interest and all other amounts owed by Curetis to the EIB under the Finance Contract was approximately 9.66 million euro and that interest will continue to accrue in accordance with the Finance Contract until all amounts owed are paid in full. Pursuant to that certain Guarantee and Indemnity Agreement, dated July 9, 2020 (the “Guaranty”), between the EIB and the Company, the EIB demanded that the Company, as guarantor, immediately repay the EIB all amounts owed to the EIB under the Finance Contract and reserved all of its other rights and remedies in connection with the Finance Contract. As of the three months ended June 30, 2024, the Guaranty remained unpaid and outstanding, with the liability reflected on the Company’s financial statements, which was previously on Curetis’ balance sheet. In connection with the Company’s entry into the March 2024 Purchase Agreement with David E. Lazar on March 25, 2024, the Company entered into settlement agreements with each of the EIB and Curetis and Curetis’ trustee in insolvency, pursuant to which the Company will pay a total of $2.0 million of the proceeds anticipated in connection with the March 2024 Purchase Agreement to settle all outstanding debt of the Company to EIB and Curetis. The settlement agreement with EIB will also terminate that certain Guarantee and Indemnity Agreement, dated as of July 9, 2020, by and between the EIB and the Company, pursuant to which the Company had guaranteed all of Curetis’ debt to EIB. As a result of delays to the final closing of the Private Placement, the settlement amounts remain unpaid; however, the Company and the EIB are in ongoing discussions regarding an amendment to such settlement agreements to cure such delays, which the Company anticipates resolving in the third quarter of 2024. Upon termination of the Guarantee and Indemnity Agreement, the Company anticipates recording a gain on extinguishment of debt in excess of $8 million.

●

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

●

On June 5, 2024, the Company received a notice from The Nasdaq Stock Market LLC (“Nasdaq”) stating that the Company is not in compliance with the minimum stockholders’ equity requirement for continued listing on Nasdaq. Nasdaq Listing Rule 5550(b)(1) requires companies listed on the Nasdaq Capital Market to maintain stockholders’ equity of at least $2,500,000 or to meet the alternatives of market value of listed securities or net income from continuing operations. The notice indicated that such deficiency serves as an additional basis for delisting the Company’s securities from Nasdaq. In accordance with the notice, the Company submitted its response to the Nasdaq Hearings Panel in June 2024 regarding the Company’s plan to cure such deficiency and the Company remains in ongoing discussions with Nasdaq regarding its plan. As with the prior notices received by the Company, the most recent notice from Nasdaq has no immediate effect on the listing of the Company’s securities on The Nasdaq Capital Market. There can be no assurance that the Nasdaq Hearings Panel will grant the Company additional time to cure such deficiency or, if additional time is granted, that the Company will be able to regain compliance with the requirements for continued listing.

Although AEI Capital Ltd., which purchased the rights to the additional 2,450,000 shares of Series E Preferred Stock under the March 2024 Purchase Agreement, provided the Company with $2.45 million in additional funding through August 15, 2024, the Company believes that current cash will only be sufficient to fund operations into the third quarter of 2024. This has led management to conclude that there is substantial doubt about the Company’s ability to continue as a going concern. In the event the Company does not receive additional funding from AEI Capital Ltd. or other investors or find a strategic transaction partner before or during the third quarter of 2024, the Company will not have sufficient cash flows and liquidity to finance its business operations. Accordingly, in such circumstances, the Company would be compelled to immediately reduce general and administrative expenses until it is able to obtain sufficient financing. If such sufficient financing is not received on a timely basis, the Company would then need to pursue a plan to seek to be acquired by another entity, cease operations and/or seek bankruptcy protection. There can be no assurance that the Company will be able to identify or execute on any of these alternatives on acceptable terms or that any of these alternatives will be successful.

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

Summary of Significant Accounting Policies (Policies)

Accounting Policies [Abstract]

Basis of presentation and consolidation

Basis of presentation and consolidation

The Company has prepared the accompanying unaudited condensed consolidated financial statements pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) and the standards of accounting measurement set forth in the Interim Reporting Topic of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”). Certain information and note disclosures normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted, although the Company believes that the disclosures made are adequate to make the information not misleading. The Company recommends that the unaudited condensed consolidated financial statements be read in conjunction with the audited consolidated financial statements and the notes thereto included in the Company’s latest Annual Report on Form 10-K. In the opinion of management, all adjustments that are necessary for a fair presentation of the Company’s financial position for the periods presented have been reflected. All adjustments are of a normal, recurring nature, unless otherwise stated. The interim condensed consolidated results of operations are not necessarily indicative of the results that may occur for the full fiscal year. The December 31, 2023 consolidated balance sheet included herein was derived from the audited consolidated financial statements, but does not include all disclosures including notes required by GAAP for complete financial statements.

The accompanying unaudited condensed consolidated financial statements include the accounts of OpGen as of and for the three and six months ended June 30, 2024; all intercompany transactions and balances have been eliminated.

Foreign currency

Foreign currency

In prior years, the Company had foreign subsidiaries, each of which use currencies other than the U.S. dollar as their functional currency. As a result, all assets and liabilities of the subsidiaries are translated into U.S. dollars based on exchange rates at the end of the reporting period. Income and expense items are translated at the average exchange rates prevailing during the reporting period. Translation adjustments are reported in accumulated other comprehensive income (loss), a component of stockholders’ equity. Foreign currency translation adjustments are the sole component of accumulated other comprehensive income (loss) at December 31, 2023.

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

Immaterial Out of Period Adjustments

Immaterial Out of Period Adjustments

During the three months ended March 31, 2024, the Company identified an immaterial error related to the calculation of preferred stock par value and additional paid-in capital for the Company’s Series D convertible preferred stock that impacted the Company’s previously issued 2023 consolidated financial statements. Management evaluated the effect of the error on the 2023 and current period consolidated financial statements and concluded the error was not material. As a result, in the three months ended March 31, 2024, the Company recorded an out of period adjustment to decrease preferred stock par value and increase additional paid-in capital, each by approximately $2.5 thousand.

During the three months ended March 31, 2024, the Company identified an immaterial error related to the inclusion of balances of accumulated other comprehensive loss representing historic translation adjustments of previously dissolved subsidiaries that impacted the Company’s previously issued 2023 and 2022 consolidated financial statements. Management evaluated the effect of the error on the 2023, 2022, and current period consolidated financial statements and concluded the error was not material. As a result, in the three months ended March 31, 2024, the Company recorded an out of period adjustment to increase the loss on deconsolidation of subsidiaries and decrease accumulated other comprehensive loss, each by approximately $75.1 75,138 thousand.

Restatement of Prior Period Financial Statements

Restatement of Prior Period Financial Statements

Subsequent to the filing of the Company’s Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2024, the Company identified an error relating to the accounting treatment of an indemnification asset in the Company’s previously issued unaudited condensed consolidated financial statements included in the Company’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2024 (the “Affected Period”). As a result, the Company filed an amended Form 10-Q for the quarterly period ended March 31, 2024 to correct the error in the Affected Period by adjusting the following information for the three months ended March 31, 2024: (i) removing the previously recorded indemnification asset and gain on lease indemnification; and (ii) changing the accounting estimates related to the Company’s operating lease right-of-use asset and leasehold improvement property and equipment and recording a gain on impairment adjustment associated with the Rockville, Maryland office due to the identification of a subtenant in the three months ended March 31, 2024. In total, the restatement and associated change in accounting estimates resulted in an incremental loss of approximately $0.1 million.

Use of estimates

Use of estimates

In preparing financial statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. In the accompanying unaudited condensed consolidated financial statements, estimates are used for, but not limited to, liquidity assumptions, revenue recognition, stock-based compensation, allowances for doubtful accounts and inventory obsolescence, property and equipment, lease right-of-use assets, discount rates used to discount unpaid lease payments to present values, valuation of derivative financial instruments measured at fair value on a recurring basis, and deferred tax assets and liabilities and related valuation allowance. Actual results could differ from those estimates.

Fair value of financial instruments

Fair value of financial instruments

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

Cash and cash equivalents and restricted cash

Cash and cash equivalents and restricted cash

The Company considers all highly liquid instruments with original maturities of three months or less to be cash equivalents. The Company has cash and cash equivalents deposited in financial institutions in which the balances occasionally exceed the Federal Deposit Insurance Corporation (“FDIC”) insured limit of $250,000.

At June 30, 2024 and December 31, 2023, the Company had funds totaling $302,262 which are required as collateral for letters of credit benefiting its landlords and for credit card processors. These funds are reflected in other noncurrent assets on the accompanying unaudited condensed consolidated balance sheets.

The following table provides a reconciliation of cash and cash equivalents and restricted cash reported within the condensed consolidated balance sheets:


	June 30, 2024		December 31, 2023		June 30, 2023		December 31, 2022

Accounts receivable

Accounts receivable

The Company’s accounts receivable result from amounts invoiced but not yet collected from customers. Credit is extended based on an evaluation of a customer’s financial condition and, generally, collateral is not required. Accounts receivable are due within 30 to 90 days and are stated at amounts due from customers. The Company evaluates if an allowance is necessary by considering a number of factors, including the length of time accounts receivable are past due, the Company’s previous loss history and the customer’s current ability to pay its obligation. If amounts become uncollectible, they are charged to operations when that determination is made. The allowance for doubtful accounts was $0 as of June 30, 2024 and December 31, 2023.

At June 30, 2024, the Company had accounts receivable from two customers which individually represented 75% and 21% of total accounts receivable. At December 31, 2023, the Company had accounts receivable from three customers which individually represented 39%, 26%, and 10% of total accounts receivable. For the three months ended June 30, 2024, revenue earned from one customer represented 100% of total revenues. For the three months ended June 30, 2023, revenue earned from three customers represented 25%, 19%, and 13% of total revenues. For the six months ended June 30, 2024, revenue earned from two customers represented 48% and 14% of total revenues. For the six months ended June 30, 2023, revenue earned from two customers represented 37% and 16% of total revenues.

Inventory

Inventory

Inventories are valued using the first-in, first-out cost method and stated at the lower of cost or net realizable value and consist of the following:

Schedule of inventories
	June 30, 2024			December 31, 2023
Raw materials and supplies	$	-		$	-
Work-in-process		-			-
Finished goods		1,225,975			1,280,805
Total, gross		1,225,975			1,280,805
Less inventory reserve		(1,225,975	)		(1,280,805	)
Total, net of inventory reserve	$	-		$	-

Inventory includes Unyvero system instruments and components and systems related to the Acuitas business.

The Company periodically reviews inventory quantities on hand and analyzes the provision for excess and obsolete inventory based primarily on product expiration dating and its estimated sales forecast, which is based on sales history and anticipated future demand. The Company’s estimates of future product demand may not be accurate, and it may understate or overstate the provision required for excess and obsolete inventory. Accordingly, any significant unanticipated changes in demand could have a significant impact on the value of the Company’s inventory and results of operations. Based on the Company’s assumptions and estimates, inventory reserves for obsolescence, expirations, and slow-moving inventory were $1,225,975 and $1,280,805 at June 30, 2024 and December 31, 2023, respectively. Due to the insolvency proceedings and deconsolidation of the Company’s subsidiaries for the year ended December 31, 2023, the Company reserved for the full value of its inventory at June 30, 2024 and December 31, 2023 given the uncertainty surrounding the net realizable value and future demand for the Company’s products.

Long-lived assets

Long-lived assets

Property and equipment

Property and equipment is reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. Recoverability measurement and estimating of undiscounted cash flows is done at the lowest possible level for which we can identify assets. If such assets are considered to be impaired, impairment is recognized as the amount by which the carrying amount of assets exceeds the fair value of the assets. During the year ended December 31, 2023, the Company determined that all of its property and equipment, including leasehold improvements and computer and networking equipment, at its Rockville, MD office was impaired due to the Company’s financial condition and the impairment of the Company’s ROU lease asset. As a result, the Company recorded an impairment charge in the amount of $1,231,874. In the Company’s Amended Form 10-Q for the three months ended March 31, 2024, the Company recorded a change in accounting estimate on the Company’s leasehold improvement property and equipment, bringing the balance as of the beginning of the period back to $1,230,332 following the Company’s identification of a subtenant. During the three and six months ended June 30, 2024 and 2023, the Company determined that its property and equipment was not impaired.

Leases

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

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

ROU assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. Recoverability measurement and estimating of undiscounted cash flows is done at the lowest possible level for which the Company can identify assets. If such assets are considered to be impaired, impairment is recognized as the amount by which the carrying amount of assets exceeds the fair value of the assets. During the year ended December 31, 2023, the Company determined that its operating lease right-of-use asset for its Rockville, MD office was impaired due to the Company’s inability to support the lease given its financial position. As a result, the Company recorded an impairment charge in the amount of $849,243. In the Company’s Amended Form 10-Q for the three months ended March 31, 2024, the Company recorded a change in accounting estimate on the Company’s operating lease right-of-use asset, bringing the balance as of the beginning of the period back to $849,243 following the Company’s identification of a subtenant. The Company did not identify any impaired ROU assets for the six months ended June 30, 2024 and 2023.

Intangible assets

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

Intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. If any indicators were present, the Company would test for recoverability by comparing the carrying amount of the asset to the net undiscounted cash flows expected to be generated from the asset. If those net undiscounted cash flows do not exceed the carrying amount (i.e., the asset is not recoverable), the Company would perform the next step, which is to determine the fair value of the asset and record an impairment loss, if any. All the Company’s finite-lived intangible assets with net balances were held by Curetis and Ares Genetics. As a result of the insolvency filings for Curetis and Ares Genetics and the associated deconsolidation of all balance sheet balances related to these entities in 2023, the Company does not have any finite-lived or indefinite-lived intangible asset balances as of June 30, 2024.

Total amortization expense of intangible assets was $0 and $187,540 for the three months ended June 30, 2024 and 2023, respectively. Due to the removal of the intangible assets of Curetis and Ares Genetics in 2023 and the Company’s absence of intangible assets as of June 30, 2024, the Company does not currently anticipate any future amortization of intangible assets.

Revenue recognition

Revenue recognition

During the six months ended June 30, 2024 and 2023, the Company derived revenues from (i) the sale of Unyvero Application cartridges, Unyvero Systems, Acuitas AMR Gene Panel systems and test products, and SARS CoV-2 tests, (ii) providing laboratory services, and (iii) providing collaboration services including funded software arrangements, license arrangements, and the Foundation for Innovative New Diagnostics (FIND) NGO collaboration on our Unyvero A30 platform.

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

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

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

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

Government grant agreements and research incentives

Government grant agreements and research incentives

From time to time, the Company may enter into arrangements with governmental entities for the purposes of obtaining funding for research and development activities. The Company recognized funding from grants and research incentives received from Austrian government agencies in the condensed consolidated statements of operations and comprehensive loss in the period during which the related qualifying expenses are incurred, provided that the conditions under which the grants or incentives were provided have been met. For grants under funding agreements and for proceeds under research incentive programs, the Company recognizes grant and incentive income in an amount equal to the estimated qualifying expenses incurred in each period multiplied by the applicable reimbursement percentage. The Company classifies government grants received under these arrangements as a reduction to the related research and development expense incurred. The Company analyzes each arrangement on a case-by-case basis. For the three months ended June 30, 2023, the Company recognized $88,421 as a reduction of research and development expense related to government grant arrangements. For the six months ended June 30, 2023, the Company recognized $222,359 as a reduction of research and development expense related to government grant arrangements. As of June 30, 2024, the Company does not have any active grants.

Research and development costs, net

Research and development costs, net

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

Stock-based compensation

Stock-based compensation

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

Option valuation models, including the Black-Scholes model, require the input of highly subjective assumptions, and changes in the assumptions used can materially affect the grant-date fair value of an award. These assumptions include the risk-free rate of interest, expected dividend yield, expected volatility and the expected life of the award.

Warrants

Warrants

The Company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the instruments’ specific terms and applicable authoritative guidance in ASC 480, Distinguishing Liabilities from Equity (“ASC 480”), and ASC 815, Derivatives and Hedging (“ASC 815”). The assessment considers whether the instruments are free standing financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the instruments meet all of the requirements for equity classification under ASC 815, including whether the instruments are indexed to the Company’s own ordinary shares and whether the instrument holders could potentially require “net cash settlement” in a circumstance outside of the Company’s control, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent period end date while the instruments are outstanding.

Income taxes

Income taxes

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

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

The Company had federal net operating loss (“NOL”) carryforwards of $241,110,447 and $232,682,072 at December 31, 2023 and 2022, respectively. Despite the NOL carryforwards, which started expiring in 2022, the Company may have state tax requirements. Also, use of the NOL carryforwards may be subject to an annual limitation as provided by Section 382 of the Internal Revenue Code of 1986, as amended (the “Code”). To date, the Company has not performed a formal study to determine if any of its remaining NOL and credit attributes might be further limited due to the ownership change rules of Section 382 or Section 383 of the Code. The Company will continue to monitor this matter going forward. There can be no assurance that the NOL carryforwards will ever be fully utilized.

Net income (loss) per share

Net income (loss) per share

In periods of net loss, basic loss per share is computed by dividing net loss available to common stockholders by the weighted average number of shares of common stock outstanding during the period. The Company’s Series D and E convertible preferred stock contains non-forfeitable rights to dividends, and therefore are considered to be participating securities; in periods of net income, the calculation of basic earnings per share excludes from the numerator net income attributable to the preferred stock and excludes the impact of those shares from the denominator.

In periods of net loss, diluted loss per share is calculated similarly to basic loss per share because the impact of all potential dilutive common shares is anti-dilutive. In periods of net income, diluted earnings per share is computed using the more dilutive of the “two class method” or the “treasury method.” Dilutive earnings per share under the “two class method” is calculated by dividing net income available to common stockholders as adjusted for the participating impacts of the preferred stock, by the weighted-average number of shares outstanding plus the dilutive impact of all other potential dilutive common shares, consisting primarily of common shares underlying common stock options and stock purchase warrants using the treasury stock method. Dilutive earnings per share under the “treasury stock method” is calculated by dividing net income available to common stockholders by the weighted-average number of shares outstanding plus the dilutive impact of all potential dilutive common shares, consisting primarily of common shares underlying common stock options and stock purchase warrants using the treasury stock method, and preferred stock using the if-converted method.

None of the potential dilutive securities had a dilutive impact during the three and six months ended June 30, 2024 and 2023 due to the Company’s net loss positions.

The number of anti-dilutive shares for the six months ended June 30, 2024 and 2023, consisting of common shares underlying (i) common stock options, (ii) restricted stock units, (iii) preferred stock, and (iv) stock purchase warrants which have been excluded from the computation of diluted income per share, was 2.5 million and 1.1 million shares, respectively.

Note 11 – Subsequent Events

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

Other than as disclosed in this Note 11 and as may be disclosed elsewhere in the notes to the accompanying unaudited condensed consolidated financial statements, there have been no subsequent events that require adjustment or disclosure in the accompanying unaudited condensed consolidated financial statements.

On July 31, 2024, David E. Lazar, the Company’s former Chief Executive Officer and Chairman of the Board of Directors (the “Board”), consummated a transaction pursuant to which he sold 550,000 shares of Series E Convertible Preferred Stock (the “Series E Stock”) of the Company together with his rights to purchase the additional 2,450,000 shares of Series E Stock under that certain Securities Purchase Agreement, dated March 25, 2024 (the “March 2024 Purchase Agreement”), entered into between Mr. Lazar and the Company, to AEI Capital Ltd. (the “Purchaser”) for $2,550,000 (the “Transaction”). In connection with the consummation of the Transaction, Mr. Lazar resigned as Chief Executive Officer, Chairman and Director of the Company effective August 2, 2024, and the Board appointed John Tan Honjian, a designee of the Purchaser, as Chief Executive Officer, Chairman and Director of the Company. Mr. Lazar also agreed to continue his services to the Company in the role of President for a period of at least sixty days following the consummation of the Transaction. In lieu of amounts owed by the Company to Mr. Lazar upon his resignation pursuant to his employment agreement, dated April 11, 2024, with the Company, and his director agreement, dated March 25, 2024 (the “CEO Agreements”), Mr. Lazar accepted shares of common stock, par value $0.01, of the Company (the “Common Stock”). In connection with the Transaction, on July 29, 2024, each of Avraham Ben-Tzvi, Matthew C. McMurdo and David Natan delivered notice of their resignation as a member of the Board and all committees thereof effective and contingent the successful consummation of the Transaction, the receipt by such directors of all amounts owed by the Company to such directors pursuant to each of their director agreements, dated March 25, 2024, entered into by each such director with the Company and the satisfaction of certain other conditions. Such resignations from the Board became effective on August 2, 2024 and were not a result of a disagreement with the Company or the Board on any matter relating to the Company’s operations, policies or practices or any other matter. As of August 15, 2024, the Purchaser funded the remaining $2.45 million in exchange for the remaining 2,450,000 shares of Series E Stock under the March 2024 Purchase Agreement. As a result of the Transaction, along with the additional fundings of $2.45 million, AEI Capital Ltd. received an aggregate amount of 3,000,000 shares of Series E Stock, of which 2,736,039 shares of Series E Stock have been converted into 6,566,494 shares of the Company’s common stock as of August 16, 2024. The Purchaser currently holds approximately 79.6% of the outstanding voting securities of the Company on an as-converted to Common Stock basis. The Company was subsequently informed that the Purchaser entered into an agreement to sell 263,961 shares of Series E Stock, or approximately 7.0% of the outstanding voting securities of the Company on an as-converted to Common Stock basis. Such sale of the 263,961 shares of Series E Stock is expected to close during August 2024. Once the sale is consummated, the Purchaser will hold approximately 72.6% of the outstanding voting securities of the Company on an as-converted to Common Stock basis. As of the filing of this Quarterly Report on Form 10-Q for the three months ended June 30, 2024, the Company has cash and cash equivalents of approximately $2.16 million. The Company intends to use the majority of the proceeds to settle the outstanding liabilities amongst the EIB and Curetis’ trustee in insolvency. By settling with these parties, the Guarantee and Indemnity Agreement, dated as of July 9, 2020, by and between the EIB and the Company, will be terminated, and following such termination, the Company anticipates recording a gain on extinguishment of debt in excess of $8 million.

On August 14, 2024, management of the Company, in consultation with the Company’s Board of Directors and the Company’s independent registered public accounting firm, concluded that the Company’s previously issued unaudited condensed consolidated financial statements contained within its Quarterly Report on Form 10-Q for the period ended March 31, 2024 (the “Q1 2024 Financial Statements”) should no longer be relied upon due to an error in the financial statements that necessitated a restatement of such prior period financial statements. The error related to the accounting treatment of an indemnification asset arising from the Company’s Rockville, Maryland office lease in the Q1 2024 Financial Statements. During the three months ended March 31, 2024, the Company identified a subtenant for the office lease, and as a result, in the Q1 2024 Financial Statements, the Company recorded an indemnification asset and associated gain on lease indemnification to reflect the new subtenant’s agreement to indemnify the Company from any claims, obligations, or liabilities that may arise during their tenancy beginning on April 1, 2024. The Company subsequently determined that this accounting was incorrect and that it should continue to account for the headlease as a continuing operating lease and the lease assignment as a sublease. Based on the foregoing, the Company corrected such error by restating the Q1 2024 Financial Statements in an amended Quarterly Report on Form 10-Q for the affected period.

EIB Loan Facility

In 2016, Curetis entered into a contract for an up to €25.0 million senior, unsecured loan financing facility from the EIB. The funding could be drawn in up to five tranches within 36 months of entry into the contract, under the EIB amendment, and each tranche was to be repaid upon maturity 5 five years after draw-down.

In April 2017, Curetis drew down a first tranche of €10.0 million from this facility. This tranche had a floating interest rate of EURIBOR plus 4% payable after each 12-month-period from the draw-down-date and another additional 6% interest per annum that is deferred and payable at maturity together with the principal. In June 2018, a second tranche of €3.0 million was drawn down. The terms and conditions are analogous to the first one. In June 2019, Curetis drew down a third tranche of €5.0 million from the EIB. In line with all prior tranches, the majority of interest is also deferred until repayment upon maturity. In return for the EIB waiving the condition precedent of a minimum cumulative equity capital raised of €15.0 million to disburse this €5.0 million third tranche, the parties agreed on a 2.1% PPI. Upon maturity of the tranche, the EIB would be entitled to an additional payment that is equity-linked and equivalent to 2.1% of the then total valuation of Curetis N.V. As part of the amendment between the Company and the EIB on July 9, 2020, the parties adjusted the PPI percentage applicable to the third EIB tranche of €5.0 million, which was funded in June 2019, from its original 2.1% PPI in Curetis N.V.’s equity value upon maturity to a new 0.3% PPI in OpGen’s equity value upon maturity. This right constituted an embedded derivative, which is separated and measured at fair value with changes being accounted for through income or loss. The EIB debt was measured and recognized at fair value as of the acquisition date. The fair value of the EIB debt was approximately €14.4 million (approximately $15.8 million) as of the acquisition date. The resulting debt discount was to be amortized over the life of the EIB debt as an increase to interest expense.

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

On November 20, 2023, Curetis received a termination notice from the EIB terminating the Standstill Agreement effective as of November 20, 2023. The EIB’s termination notice stated that the termination of the Standstill Agreement was as a result of and in connection with certain defaults of the Standstill Agreement arising from, among other related reasons, Curetis’ and Ares’ entry into insolvency proceedings. On December 4, 2023, the Company received a notice from the EIB stating that Curetis is in default of the Finance Contract as a result of, among other things, Curetis’ failure to repay when due certain outstanding indebtedness under the Finance Contract. In its notice, the EIB stated that, as of November 16, 2023, the aggregate amount of principal, accrued interest and all other amounts owed by Curetis to the EIB under the Finance Contract was approximately 9.66 million euro and that interest will continue to accrue in accordance with the Finance Contract until all amounts owed are paid in full. Pursuant to that certain Guarantee and Indemnity Agreement, dated July 9, 2020 (the “Guaranty”), between the EIB and the Company, the EIB demanded that the Company, as guarantor, immediately repay the EIB all amounts owed to the EIB under the Finance Contract and reserved all of its other rights and remedies in connection with the Finance Contract. As of the three months ended June 30, 2024, the Guaranty remained unpaid and outstanding, with the liability reflected on the Company’s financial statements, which was previously on Curetis’ balance sheet.

In connection with the Company’s entry into the March 2024 Purchase Agreement with David E. Lazar on March 25, 2024, the Company entered into settlement agreements with each of the EIB and Curetis and Curetis’ trustee in insolvency, pursuant to which the Company will pay a total of $2.0 million of the proceeds anticipated in connection with the March 2024 Purchase Agreement to settle all outstanding debt of the Company to EIB and Curetis. The settlement agreement with EIB will also terminate that certain Guarantee and Indemnity Agreement, dated as of July 9, 2020, by and between the EIB and the Company, pursuant to which the Company had guaranteed all of Curetis’ debt to EIB. As a result of delays to the final closing of the Private Placement, the settlement amounts remain unpaid; however, the Company and the EIB are in ongoing discussions regarding an amendment to such settlement agreements to cure such delays, which the Company anticipates resolving in the third quarter of 2024. Upon termination of the Guarantee and Indemnity Agreement, the Company anticipates recording a gain on extinguishment of debt in excess of $8 million.

As of June 30, 2024, the outstanding borrowings under all tranches were €10.4 million (approximately $11.1 million), including deferred interest payable at maturity of €1.7 million (approximately $1.9 million).

Total interest expense (including amortization of debt discounts and financing fees) on all debt instruments was $1,079 and $684,498 for the three months ended June 30, 2024 and 2023, respectively. Total interest expense (including amortization of debt discounts and financing fees) on all debt instruments was $1,079 and $1,301,796 for the six months ended June 30, 2024 and 2023, respectively. Upon deconsolidation of the Company’s subsidiaries in 2023, the Company reclassified the EIB liability from a loan to a loan guaranty which is recorded based on its fair value with changes being recognized as part of net income at each reporting date.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Organization

Note 1 – Organization

OpGen, Inc. (“OpGen” or the “Company”) was incorporated in Delaware in 2001. On April 1, 2020, OpGen completed its business combination transaction (the “Transaction”) with Curetis N.V., a public company with limited liability under the laws of the Netherlands (the “Seller” or “Curetis N.V.”), as contemplated by the Implementation Agreement, dated as of September 4, 2019 (the “Implementation Agreement”) by and among the Company, the Seller, and Crystal GmbH, a private limited liability company organized under the laws of the Federal Republic of Germany and wholly owned subsidiary of the Company (the “Purchaser”). Pursuant to the Implementation Agreement, the Purchaser acquired all the shares of Curetis GmbH, a private limited liability company organized under the laws of the Federal Republic of Germany (“Curetis GmbH”), and certain other assets and liabilities of the Seller (together, “Curetis”). As of December 31, 2022, Crystal GmbH has been dissolved and merged into Curetis GmbH. On November 6, 2023, Curetis filed a petition for insolvency with the district court of Stuttgart, Germany, and Ares Genetics filed a petition for insolvency with the commercial court in Vienna, Austria, and insolvency administrators in the respective jurisdictions assumed control over the assets and liabilities of these entities. The Company’s headquarters and principal operations were located at 9717 Key West Avenue, Suite 100, in Rockville, Maryland, through the end of the first quarter of 2024. Upon assignment of the Company’s lease, the Company operates virtually. The Company operates in one business segment.

OpGen Overview

From inception through November 2023, OpGen operated as a precision medicine company harnessing the power of molecular diagnostics and informatics to help combat infectious disease. The Company, along with its subsidiaries, Curetis and Ares Genetics, developed and commercialized molecular microbiology solutions helping to guide clinicians with more rapid and actionable information about life threatening infections to improve patient outcomes and decrease the spread of infections caused by multidrug-resistant microorganisms, or MDROs.

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

The insolvency administrators assumed control over the assets and liabilities of Curetis and Ares Genetics, respectively, which eliminated the authority and power of the Company and its officers to act on behalf of the subsidiaries. The loss of control required that the Company no longer include Curetis and Ares Genetics in its consolidated financial statements. Prior to the insolvency filings, Curetis and Ares Genetics had been included in the Company’s consolidated financial statements. As part of the insolvency proceedings, in April 2024, the insolvency administrator for Curetis notified the Company that all of Curetis’ assets were sold to Camtech Pte Ltd., a Singaporean family office (“Camtech”). In April 2024, the insolvency administrator for Ares Genetics notified the Company that all of Ares Genetics’ assets were sold to bioMerieux S.A.

On April 23, 2024, the Company entered into a letter agreement with Camtech for the sale of certain of the Company’s inventory and customer contracts for its Unyvero products. The transaction was entered into following the prior acquisition by Camtech in April 2024 of the assets from the Company’s subsidiary, Curetis, as part of Curetis’ insolvency proceedings. The purchase price for the transaction is $218,000, and the transaction closed in May 2024. As part of such letter agreement, the Company also offered Camtech the opportunity to purchase its remaining Unyvero inventory and assets for up to an additional $176,000. Until such sale for the remaining inventory is completed, the Company will maintain commercial operations and service support for the Unyvero systems. The foregoing transactions are part of the Company’s planned exit from its Unyvero business, as the Company continues to seek strategic alternatives. Additionally, the sale of Ares Genetics’ related products and services was discontinued during the first quarter of 2024 due to the sale of the Ares Genetics assets to a strategic acquiror by its insolvency administrator in Austria.

On May 9, 2024, the Company held a special meeting of stockholders (the “Special Meeting”). The Company’s stockholders voted on three proposals, each of which was described in the Company’s proxy statement for the Special Meeting dated May 9, 2024. The following proposals were voted upon and approved at the Special Meeting: (1) a proposal to (i) approve the issuance to David E. Lazar of the common stock issuable upon the conversion of the Company’s Series E Preferred Stock in excess of applicable beneficial ownership limitations, the issuance of which would result in a “change of control” under the rules of The Nasdaq Capital Market and (ii) approve an amendment of the Certificate of Designation for the Series E Preferred Stock removing such ownership limitations; and (2) a proposal to approve the amendment to the Company’s Amended and Restated Certificate of Incorporation, as amended (the “Charter”), to effect a reverse stock split at a ratio not less than two-to-one and not more than ten-to-one, such ratio and the implementation and timing of such reverse stock split to be determined in the discretion of our Board of Directors. Following the approval of the amendment of the Certificate of Designation, the Company filed the amendment with the Secretary of State of the State of Delaware on May 9, 2024. Except for the removal of the Ownership Limitation, the amendment does not make any other changes to the Certificate of Designation.

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