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 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. Furthermore, on April 11, 2024, the Company entered into an employment agreement with David E. Lazar. Pursuant to the employment agreement, the Company engaged Mr. Lazar to act as its Chief Executive Officer (“CEO”). 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. (see Note 11). In connection with the closing of such transaction, Mr. Lazar resigned as a Director and CEO of the Company and agreed to terminate his employment agreement, each as of August 2, 2024. The focus of OpGen going forward under new leadership continues to be on the sale of the Company or the identification of a privately held company to complete a reverse merger or similar strategic transaction. 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.
