(OTCPK: ATDS) (“Data443” or the “Company”), a data security and privacy software company for “All Things Data Security,” today provided an update on the definitive Business Combination Agreement (the “Business Combination Agreement”), dated as of August 27, 2026, among Four Leaf, FORL Merger Sub, Inc., a Nevada corporation and wholly-owned subsidiary of Four Leaf, and Data443. The parties are proceeding with preparation of a registration statement on Form S-4 and, upon consummation of the transactions contemplated by the Business Combination Agreement, intend for the combined company to be listed on the Nasdaq Stock Market pending approvals. Completion of the transactions remains subject to the approval of Four Leaf’s stockholders, effectiveness of the Form S-4, approval of the combined company’s securities for listing on Nasdaq, and the satisfaction or waiver of the other closing conditions described below and in the Business Combination Agreement. There can be no assurance that the transactions will be completed. Building the Combined Company: Data Security, Ledger Validation and AI Data443 provides data classification, data discovery, privacy, compliance, threat detection and defensible disposition software to enterprise and government customers. The Company also has a multi-year operating record in distributed-ledger infrastructure as an operator within the Unique Node List (UNL) ecosystem of a major distributed ledger network, where it has maintained high-availability validator nodes. Operating with technical neutrality, Data443 does not participate in token rewards or economic incentives, which the Company believes supports impartiality in transaction ordering and proposal validation. Vaikora provides AI Security (actions, governance, data flows and agent to agent communications) in commercial and specific open-source models. Convaa.ai is the first true multi-person, multi-organization, multiple model collaboration product, deeply integrated to the Vaikora platform for personal and multi-team privacy and data exposure mitigation. Data443 intends to pursue the following priorities as a combined company: <table style="border-collapse: collapse; width:100%; border-collapse:collapse ;"><tr><td style="vertical-align: top ; "> </td><td style="vertical-align: top ; ">●</td><td style="text-align: justify ; vertical-align: middle; vertical-align: top ; ">Deepen its investment in client-facing AI technology, including Convaa.ai and Vaikora.com technology set.</td></tr><tr><td style="vertical-align: top ; "> </td><td style="vertical-align: top ; "> </td><td style="text-align: justify ; vertical-align: middle; vertical-align: top ; "> </td></tr><tr><td style="text-align: justify ; vertical-align: middle; vertical-align: top ; "> </td><td style="vertical-align: top ; ">●</td><td style="text-align: justify ; vertical-align: middle; vertical-align: top ; ">Advancing AI-driven detection, analytics and remediation across its threat intelligence and data protection portfolio.

There can be no assurance that any of these initiatives will be undertaken, completed, or produce the anticipated benefits. Executive Commentary “Entering into this agreement is a step toward giving Data443 a major-market platform for the next phase of our growth,” said Jason Remillard, Chief Executive Officer and Founder of Data443. “We have spent nearly a decade building enterprise-grade data security and a validation record in distributed-ledger infrastructure. Our focus now is on executing the registration statement process, satisfying the listing requirements, and continuing to invest in the AI and data protection capabilities our customers are asking for. Completion of the transaction is subject to stockholder approval and other conditions, and we will let the Form S-4 speak for the details.” Certain Risks and Uncertainties Relating to the Proposed Transaction Investors and stockholders should carefully consider the risk factors that will appear in the Form S-4 and in the parties’ reports filed with the Securities and Exchange Commission.
