Granted U.S. Patent Covers Technology for Maintaining Precise UAV Control When Communication Latency Impacts Operator Command TAMPA, Fla., June 16, 2026 (GLOBE NEWSWIRE) -- JFB Construction Holdings (Nasdaq: JFB) announced that XTEND, a leader in software systems and artificial intelligence-powered robotics, has secured a U.S. patent protecting technology that enables unmanned aerial vehicles (UAVs) to maintain precise, reliable control when communications are degraded and latency impacts operator demand. U.S. Patent No. 12,461,522 covers remote, accurate maneuvering of an unmanned aerial vehicle under communication latency, addressing one of the most fundamental challenges in autonomous and remotely operated systems. Disrupted communications and signal delay are increasingly the norm in modern contested environments, making the ability to sustain reliable UAV control under those conditions operationally critical. XTEND's patented technology allows operators to deploy autonomous systems that hold course and stay on target despite adverse conditions. "Reliable autonomy has to hold up in every operational scenario, especially when communications are degraded and the environment becomes unpredictable," said Aviv Shapira, Co-Founder and CEO of XTEND. "Owning this intellectual property protects the capabilities that set our systems apart and makes them difficult for others to replicate. Now, as we scale across global defense and security markets, the technology behind that critical differentiation stays defensibly ours." This patent complements XTEND's broader software and autonomy strategy. The company's XOS operating system enables operators to manage, supervise, and deploy autonomous robotic systems across air, ground, and maritime domains. By combining artificial intelligence, autonomy, and human decision-making, XOS allows operators to extend operational reach while maintaining meaningful oversight and control across autonomous assets operating in complex environments. Securing this intellectual property is part of a sustained investment in the autonomy, navigation, and control technologies that XTEND continues to advance as demand for resilient unmanned systems grows worldwide. +++ 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. Following the closing of the business combination, the joint company is expected to be renamed XTEND AI Robotics and be listed on a U.S. national securities exchange under the ticker symbol “XTND.” About XTEND XTEND is a leader in software systems and artificial intelligence-powered robotics, deployed in high-threat, complex operational environments where human exposure carries significant risk.

Investment deepens the companies' existing supply and manufacturing relationship as Powerus advances its proposed business combination Powerus has previously announced a proposed merger with Aureus Greenway Holdings Inc. (Nasdaq: PUSA); the merger has not closed and remains subject to customary closing conditions. WEST PALM BEACH, Fla., June 16, 2026 (GLOBE NEWSWIRE) -- Autonomous Power Corporation, doing business as “Powerus,” today announced a $30 million strategic investment from Unusual Machines, Inc. (NYSE American: UMAC), a domestic manufacturer of NDAA-compliant drone components. The investment strengthens a working relationship already in place between the two companies, under which Powerus sources drone components and hardware from Unusual Machines The companies' interests are closely aligned: as Powerus scales its production of autonomous and counter-drone systems, it has been and expects to be a meaningful customer for U.S.-made components of the kind Unusual Machines supplies. Powerus is under no obligation to purchase any specific volume of parts, and the two companies operate independently; the relationship reflects a shared focus on building a domestic, U.S.-based defense-autonomy supply chain. “Unusual Machines has been a valued partner as we’ve scaled, and this investment reflects the strength of that relationship and our shared commitment to American-made autonomy,” said Andrew Fox, CEO of Powerus. “The more we grow, the more we both benefit from a resilient domestic supply chain.” “We chose to work with Unusual Machines because they deliver components we trust in real-world conditions,” said Brett Velicovich, Co-Founder of Powerus. “The threats our customers face are evolving fast, and meeting them takes a supply chain that’s built here, holds up under pressure and can scale. Having them as a strategic investor lets us move faster on domestic manufacturing and put proven systems where they’re needed most.” "Powerus is quickly building autonomous and counter-UAS systems at scale. They require trusted domestic suppliers and working capital to go fast,” said Allan Evans, Chief Executive Officer of Unusual Machines. “This investment reflects our confidence in the team, their vision, and the long-term relationship we are building as part of a resilient U.S. drone and counter drone supply chain."
