OPGEN INC 8-K

What Happened
OpGen, Inc. (OPGN) filed an 8-K announcing a Supplemental Letter dated December 17, 2025 with AEI Capital Ltd. that extends the Company's ability to sell common stock to AEI under a previously disclosed Securities Purchase Agreement through December 31, 2026. The filing also reports that President David Lazar notified the company on December 18, 2025 that he will resign effective January 8, 2026; his resignation was not due to any disagreement with the company.

Key Details

• Original Securities Purchase Agreement with AEI Capital Ltd. was entered on August 22, 2024.
• First Amendment (October 3, 2024) increased available financings to three tranches totaling up to $9.0 million (previously $3.0 million) and extended the selling period to December 31, 2025.
• Supplemental Letter (December 17, 2025) further extends the Company’s ability to sell shares to AEI until December 31, 2026; the Supplemental Letter is filed as Exhibit 10.1 to the 8-K.
• David Lazar notified the company of his resignation on December 18, 2025, effective January 8, 2026; the company states there was no disagreement with management on company matters.
• The filing also includes disclosure required by Item 3.02 regarding unregistered sales of equity securities.

Why It Matters
The supplemental agreement preserves OpGen’s option to raise capital by selling common stock to AEI through the end of 2026, giving the company an extended window for potential funding — a material financing option that could affect liquidity and shareholder dilution if exercised. The announced resignation of the President is a near-term leadership change investors should note; management continuity and any planned succession will be relevant to monitor in future filings and company communications.
