XTEND selected among a limited group of companies invited to participate in next stage of major U.S. Department of Defense initiative expected to support procurement of more than 200,000 drones by 2027 XTEND set to go public through proposed merger with JFB Construction Holdings (Nasdaq: JFB) mid-2026 PALM BEACH, Fla., May 28, 2026 (GLOBE NEWSWIRE) -- JFB Construction Holdings (Nasdaq: JFB) (“JFB” or the “Company”), which recently announced its proposed business combination with XTEND, a leader in AI-powered autonomous robotics and operating systems, today announced that XTEND was selected as one of a limited group of companies invited to participate in the Phase II Qualifier of the U.S. Department of Defense’s Drone Dominance Program (“DDP”). The Drone Dominance Program is a large-scale U.S. defense initiative designed to accelerate the deployment of next-generation autonomous drone technologies across the U.S. military. According to public statements released by the program, the initiative is intended to support the procurement of more than 200,000 drones by 2027 for deployment across complex operational environments.  The Drone Dominance Program represents one of the largest emerging U.S. initiatives focused on accelerating the deployment and domestic scaling of autonomous drone systems for future military operations. XTEND was selected among a limited group of companies invited to participate in the next phase of the program, which is expected to take place this summer at Camp Grayling, Michigan. The qualifier event is expected to evaluate autonomous systems across complex operational scenarios and contested mission environments. During the qualifier event, XTEND expects to demonstrate how its proprietary XOS operating system enables scalable human-guided autonomous operations across complex and contested environments. XTEND’s proprietary XOS operating system powers human-guided autonomous platforms designed for defense, national security and public safety missions. XTEND systems have been deployed operationally in complex real-world environments and are designed to support scalable autonomous missions across defense, national security and public safety applications while enhancing operator effectiveness and reducing risk to personnel. “Modern operational environments require autonomous systems that can scale rapidly, operate reliably in contested conditions, and help keep operators out of harm’s way,” said Aviv Shapira, Co-Founder and Chief Executive Officer of XTEND. “We believe our participation in the next phase of the Drone Dominance Program reflects the growing importance of AI-powered autonomy, human-guided mission systems, and scalable operational robotics within the future U.S. defense ecosystem.” “XTEND’s advancement into the next phase of the Drone Dominance Program represents meaningful validation of the company’s autonomous systems, operational capabilities and growing role within the U.S. defense ecosystem,” said Joseph F. Basile, III, Chief Executive Officer of JFB Construction Holdings. “We believe this initiative reflects the Department of Defense’s increasing focus on scalable autonomous technologies, and XTEND is well positioned to support that evolving operational need.” +++ As announced on February 17, 2026, JFB Construction Holdings (Nasdaq: JFB) and XTEND entered into a definitive agreement to combine with XTEND in an all-stock transaction. The business combination is further supported by strategic investments from Eric Trump, Unusual Machines, American Ventures, LLC, Protego Ventures, and Aliya Capital.

Powerus’ MatrixFold Dual-Use Attack Drone is part of the next generation of American-built one-way attack drones Powerus recently announced a proposed merger with Aureus Greenway Holdings Inc. (Nasdaq: PUSA), positioning Powerus to become publicly traded upon completion WEST PALM BEACH, Fla., May 27, 2026 (GLOBE NEWSWIRE) -- Autonomous Power Corporation, doing business as "Powerus ," today announced that it has been selected to compete in the qualifier for Phase II of the Department of War's Drone Dominance Program with its MatrixFold multi-purpose attack drone. With this qualification, Powerus becomes part of the $1 billion Pentagon initiative to procure and field tens of thousands of low-cost, one-way attack drones, with the aim of accelerating combat capability and strengthening the U.S. drone manufacturing base.  Winners of the Program will have demonstrated the ability to produce capable, low-cost, secure supply chains for sUAS at scale, enabling the U.S. military to integrate these capabilities into future acquisition pathways. Following qualification, the next parts of Phase II involve a production and delivery test to prove manufacturing readiness, and the Gauntlet II to identify the most capable systems for scaling and fielding. The Gauntlet test event concludes with the delivery of sUAS orders to the winners. The Phase II Qualifier window is currently estimated for June 2026. The Powerus Matrix Series is a U.S.-made line of modular first-person view platforms designed for rapid deployment across strike, ISR, and heavy-payload missions. Built with lightweight folding airframes for rucksack and vehicle transport, the systems can be configured in seconds around a common operational architecture. The MatrixFold platform is Blue UAS-compatible and NDAA-compliant. "The math of war has changed. A thousand-dollar drone can take out a multi-million-dollar target, and whoever can put a combat-ready first-person view in a soldier's hands at scale wins that exchange," said Andrew Valkenburg, Executive Vice President of Technology and Manufacturing at Powerus. "Our MatrixFold platform is built for that fight. It is a multipurpose, quick-to-deploy airframe built on the same Matrix architecture already in the hands of every U.S. Service. Our manufacturing posture was designed for the volumes Phase II calls for, and we are ready to deliver." "Phase II comes down to who shows up with a drone that serves soldiers on the ground through a supply chain the Pentagon can trust," said Brett Velicovich, Co-Founder of Powerus. "The MatrixFold platform reflects what end users have asked us for, manufactured in the U.S., trusted by U.S. military units, and ready for the missions ahead." This announcement follows Powerus' previously announced merger agreement with Aureus Greenway Holdings, Inc. (AGH), a transaction that, upon completion, is expected to result in Powerus becoming publicly traded on Nasdaq. Recently, AGH announced the change of its Nasdaq ticker symbol to PUSA. About Powerus Powerus is powering the future of autonomous drone defense. Autonomous Power Corporation (APC), doing business as Powerus, is a U.S.-based platform company that acquires, integrates, and scales domestically manufactured autonomous systems for defense, critical infrastructure, and precision agriculture. Founded by a team with direct operational experience in active conflict environments worldwide, Powerus brings together field-validated technologies under a unified operating architecture supported by U.S.-based manufacturing and allied-nation partnerships. Powerus has announced a proposed merger with Aureus Greenway Holdings Inc. (Nasdaq: PUSA). For more information, visit power.us . Merger Agreement Under the terms of a previously announced agreement, Powerus will merge with and into a newly formed subsidiary of AGH, with Powerus continuing as the surviving entity and AGH adopting the name "Powerus Corporation." The combined company expects to be listed on Nasdaq under the ticker symbol "PUSA." The merger transaction was unanimously approved by the boards of directors of both companies and a majority of each company's stockholders. The transaction remains subject to customary closing conditions, including the effectiveness of a registration statement on Form S-4 covering shares of common stock offered to Powerus stockholders and receipt of required regulatory approvals.
