Quantum Cyber N.V. (QUCY) SEC filings document a Nasdaq-listed issuer whose public record includes both its former Mainz Biomed N.V. identity and its newer autonomous defense technology focus. The company’s quarterly reports and 8-K filings are important because they describe material agreements, license arrangements, property acquisition activity, capital structure matters, governance items, and operating and financial results.
For QUCY, quarterly reports can show how the company reports expenses, liabilities, share issuance, and historical operating results. Recent quarterly disclosure describes the exclusive LightShift license for quantum photonic array technology, the related accounting treatment, and the company’s issued ordinary shares. Earlier quarterly disclosure also discusses ColoAlert sales and the wind down of the prior colorectal cancer screening sales and marketing team.
Material 8-K filings are especially relevant for Quantum Cyber because they have covered the Project LightShift intellectual property license, an amendment involving BP United manufacturing and consulting services, termination of an at-the-market issuance sales agreement, a change in independent registered public accounting firm, investor presentation materials, and the Bridgeport property acquisition involving Quantum Drones Corporation and Arcade Realty LLC.
Annual reports, proxy statements, and Form 4 insider transaction reports, when available, add context on risk factors, governance, executive compensation, ownership changes, and insider trading activity. Plain-language filing summaries can help readers separate core disclosures from legal formatting, with particular attention to 10-Q reports, 10-K annual reports, Form 4 transactions, and 8-K material event filings tied to QUCY’s defense technology and manufacturing strategy.
NATAN DAVID reported acquisition or exercise transactions in this Form 4 filing.

As consideration, subject to conditions precedent, the company agreed to pay $5,000,000 in cash and issue 20,000,000 restricted shares of common stock with a six-month lock-up and a five percent average weighted volume restriction.

Quantum Cyber N.V. reported a net loss of $5.1 million for the quarter ended March 31, 2026, similar to the prior-year loss of $5.0 million. Continuing operations generated no revenue, while discontinued colorectal cancer activities produced $170,105 in revenue before being classified as held for sale.
Total operating expenses from continuing operations were $2.46 million, driven mainly by $2.12 million in general and administrative costs, including significant share-based compensation. The company ended the quarter with cash of $4.75 million and shareholders’ equity of $4.59 million, helped by $6.0 million of preferred share funding and $2.1 million from ordinary share issuances.
Management states that recurring losses, a large accumulated deficit of about $110 million, and limited revenue create “substantial doubt” about the ability to continue as a going concern.
