Organization	Note 1 – Organization OpGen, Inc. (“OpGen” or the “Company”) was incorporated in Delaware in 2001. In April 2020, OpGen completed a business combination transaction with Curetis N.V., a public company with limited liability under the laws of the Netherlands, pursuant to which the Company acquired all the shares of Curetis GmbH, a private limited liability company organized under the laws of the Federal Republic of Germany (“Curetis GmbH”), and certain other assets and liabilities of Curetis N.V., including Ares Genetics GmbH (“Ares Genetics”), a wholly-owned subsidiary of Curetis GmbH (together, “Curetis”). From inception until 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. In November 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. In March 2024, the Company entered into a securities purchase agreement (the “March 2024 Purchase Agreement”) with David E. Lazar, pursuant to which the Company agreed to sell 3,000,000 shares of Series E Convertible Preferred Stock (“Series E Preferred Stock”) to Mr. Lazar at a price of $1.00 per share for aggregate gross proceeds of $3.0 million. In connection with the transactions contemplated by the March 2024 Purchase Agreement, the members of the Board of Directors, prior to the closing of such transactions, resigned and a new Board of Directors was appointed, of which Mr. Lazar was appointed Chairman. Furthermore, in April 2024, the Company entered into an employment agreement with David E. Lazar, pursuant to which the Company engaged Mr. Lazar to act as its Chief Executive Officer (“CEO”). In April 2024, the Company entered into a lease assignment agreement where the Company assigned the lease of its Rockville, Maryland headquarters to a third party. The Company’s security deposit remains with the landlord and will be repaid over time as agreed upon with the third party assignee. The Company has a continuing liability under the lease; however, within the lease assignment agreement, the new tenant indemnifies the Company from and against any liabilities resulting from obligations arising on or after the lease assignment date. In May 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 continued 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 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 Annual Report have been adjusted to reflect the Reverse Stock Split. In July 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. In conjunction with the transaction, Mr. Lazar resigned as CEO, Chairman and Director of the Company, effective August 2, 2024, but he currently maintains a role as President. Subsequently, AEI Capital Ltd. paid the Company $2.45 million in August 2024 in exchange for the remaining 2,450,000 shares of Series E Preferred Stock under the terms of the March 2024 Purchase Agreement. All 3,000,000 shares of Series E Preferred Stock were subsequently converted into 7,200,000 shares of the Company’s common stock in August 2024. As of September 30, 2024, no shares of Series E Preferred Stock remain outstanding. Upon conversion, such shares of Series E Preferred Stock resumed the status of authorized but unissued shares of undesignated preferred stock of the Company. Under the direction of AEI Capital Ltd., the Company has continued scaling down legacy operations. The Company has repositioned itself and established a wholly-owned subsidiary, CapForce International Holdings Ltd. (“CapForce”), which has launched a new business offering listing sponsorship and consultancy services to international companies seeking to list their securities on securities exchanges. Additionally, CapForce contemplates entering the financial technology industry supporting digital investment banking activities and capital table management (see Note 13). 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.
