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.

When hospital and health system clients purchase our products, we bill them directly for the purchase of test kits and consumables. As of March 31, 2024, OpGen had an installed base of approximately 28 Unyvero A50 Analyzers across the United States in different types of hospitals and laboratories, including installations for clinical studies. The sale of Ares Genetics’ related products and services was discontinued during the first quarter of 2024 due to the sale of the Ares Genetics assets to a strategic acquiror by its insolvency administrator in Austria. In March 2024, the Company entered into a securities purchase agreement (the “March 2024 Purchase Agreement”) with David E. Lazar, pursuant to which the Company agreed to sell 3,000,000 shares of Series E Convertible Preferred Stock (“Series E Preferred Stock”) to Mr. Lazar at a price of $1.00 per share for aggregate gross proceeds of $3.0 million. In connection with the transactions contemplated by the March 2024 Purchase Agreement, the members of the Board of Directors, prior to the closing of such transactions, resigned and a new Board of Directors was appointed, of which Mr. Lazar was appointed Chairman. The focus of OpGen going forward under new leadership and a new Board of Directors will be on the sale of the Company or the identification of a privately held company to complete a reverse merger or similar strategic transaction.
