This 8-K filing by MAINZ BIOMED N.V. (MYNZ) contains a press release from Quantum Cyber N.V. (Nasdaq: QUCY), which appears to be the actual reporting entity. Quantum Cyber announced that its subsidiary, Quantum Drones Corporation, completed the acquisition of a ~50,000 sq ft industrial facility in Bridgeport, Connecticut for $2.3 million, closing on July 15, 2026. The acquisition is a key step in Quantum Cyber's strategic transition from a technology licensor to a vertically integrated autonomous defense manufacturer, positioning it to potentially participate in U.S. defense procurement, including the DoD's $55 billion FY2027 budget allocation for drone and autonomous warfare programs. However, the equipment acquisition under a separate Asset Purchase Agreement remains pending, and the company faces significant execution risks including integration, operational targets, and securing government contracts.

• · The real property acquisition was first announced via a Letter of Intent on June 8, 2026, and definitive agreements on June 29, 2026.
• · The equipment acquisition from Arcade Technology LLC under a separate Asset Purchase Agreement is still pending.

SpringBig Holdings, Inc. transferred substantially all of its assets (including its operating subsidiary SpringBig, Inc.) to secured lenders via a Delaware General Corporation Law Section 272(b) reorganization, extinguishing approximately $12.5 million in secured debt.
