Companies to jointly evaluate Swarmer’s vendor-agnostic coordination platform across Powerus air and maritime autonomous systems for defense, counter-drone, and critical-infrastructure missions Powerus and Swarmer have signed a Memorandum of Understanding (MOU) to explore integrating Swarmer’s coordination software with Powerus air and maritime autonomous systems. The collaboration targets defense, counter-UAS, border security, and critical-infrastructure missions. 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, including effectiveness of a Form S-4 registration statement and regulatory approvals. WEST PALM BEACH, Fla. and AUSTIN, Texas, June 03, 2026 (GLOBE NEWSWIRE) -- Autonomous Power Corporation, doing business as “Powerus,” and Swarmer, Inc. (Nasdaq: SWMR) (“Swarmer”) today announced that the two companies have entered into a Memorandum of Understanding (the “MOU”) to explore the technical and operational feasibility of integrating Swarmer’s vendor-agnostic swarming and coordination software with Powerus’s unified autonomous systems architecture. The collaboration is exploratory and is intended to evaluate joint deployment concepts for defense, critical infrastructure protection, border security, and counter-drone missions. Under the MOU, the companies intend to assess interoperability between Swarmer’s multi-vehicle coordination platform and Powerus air and maritime platforms, mission systems, and U.S.-based manufacturing and integration resources. The MOU establishes a framework for good-faith technical exchanges, integration testing, and demonstration planning, and does not commit either company to any production, procurement, or financial obligation. About the proposed collaboration Within the exploratory scope of the MOU, the companies may evaluate, by mutual agreement: interoperability between Swarmer’s coordination platform and Powerus heavy-lift vertical takeoff and landing (VTOL) and tactical unmanned air systems developed through PowerAir, and unmanned surface and maritime systems developed through PowerSea; coordinated multi-drone operations, including swarming, deconfliction, and distributed mission execution across heterogeneous unmanned systems; candidate concepts of operation and demonstration scenarios for counter-UAS, interceptor coordination, and critical-infrastructure protection; and manufacturing and integration feasibility, supported by Powerus’s U.S.-based production base and strategic supplier network. Any activity beyond this evaluation — including any commercial, development, licensing, or supply arrangement — would be addressed only in one or more separate definitive agreements, which the companies are under no obligation to enter into. Powerus perspective “I first met the Swarmer team during my time volunteering in Ukraine, the same experience that shaped the idea behind Powerus,” said Brett Velicovich, President of Powerus. “Their software has been proven in more than 100,000 combat missions in one of the most demanding operational environments in the world. Exploring how it could work with our U.S.-built air and maritime platforms is exactly the kind of capability our customers are asking about.” Swarmer perspective "We see a strong demand signal in the U.S. for combat-proven technology that has been deployed in Ukraine," said Alex Fink, President and U.S. CEO of Swarmer. "We look forward to partnering with Powerus to deliver reliable autonomous solutions across air, land, and sea. We have been highly impressed by the quality of Powerus' existing VTOL, first-person view (FPV), and unmanned surface vehicle (USV) platforms, and we are excited about the possibility of creating a suite of autonomous products that will allow the U.S. to dominate its adversaries across all domains." About Powerus Powerus (Autonomous Power Corporation) builds and scales unified autonomous systems designed to move, protect, and sustain critical assets in high-risk environments, with capabilities spanning heavy-lift platforms, autonomous air systems, autonomous maritime systems, mission systems, training and support, and U.S.-based manufacturing. Powerus operates through its subsidiaries, each a Powerus company. Powerus previously announced a proposed merger with Aureus Greenway Holdings Inc. (Nasdaq: PUSA); the merger has not closed and remains subject to the satisfaction of customary closing conditions, including the effectiveness of a registration statement on Form S-4 and applicable regulatory approvals.

About Swarmer Swarmer™ is a defense technology company that specializes in vendor-agnostic software which allows one operator to intuitively control hundreds of autonomous platforms in real time. Swarmer’s primary mission areas include autonomous swarm coordination, integration of multi-domain unmanned systems and AI-powered autonomy software for distributed operations. Swarmer is not a drone manufacturer and does not depend on any single platform, supplier or hardware lifecycle. Instead, Swarmer operates at the intelligence layer, developing autonomy, coordination and decision-making software that enables large numbers of low-cost unmanned systems to operate collectively as one coherent, resilient force. Swarmer’s technology has been rigorously validated in real-world kinetic environments and was first deployed in combat operations in Ukraine in April 2024. Since then, it has completed more than 100,000 combat missions, generating terabytes of proprietary data that informs its machine-learning models and enables the replication of advanced pilot performance at scale. Swarmer’s routine use in combat missions generates continuous streams of telemetry, sensor data and operational feedback which are then used to refine performance, increase resilience and accelerate learning. Swarmer has headquarters in Austin, Texas, and maintains operations and teams in Ukraine, Poland and Estonia.

Simultaneous wars in Ukraine and Iran have depleted sources of tungsten, a largely obscure metal that is used in war machinery, but also more mundane machinery like drill bits and industrial equipment. China is the dominant supplier and has wielded its control as a geopolitical weapon. A tungsten mining project in Kazakhstan is among potential new supply sources, but Trump family investment has attracted scrutiny. Almonty Industries, a Canada-based miner that has tungsten mines in South Korea and Portugal, is also interested in the potential to mine within the U.S. The Iran war has caused well-documented price spikes and shortages on a range of items Americans depend upon. Oil and gas, of course, but also petrochemicals and everything derived from them (e.g. plastics) and helium are among raw materials that have been besieged by the closure of the Strait of Hormuz . Still, there is another element which has seen its price surge amid increasingly short supply because of war, but where the shock will not relent even if the Strait is reopened. The vast amount of U.S. munitions used in battle combined with weapons shipped to Ukraine has left many U.S.-based entities in search of tungsten. If you don’t know you need tungsten, that’s understandable. While tungsten’s role in weapons is driving the current crisis, its reach extends to far more mundane corners of American life, from the dentist’s chair to the fishing hole. It flies under the radar for most people, but not those within supply chains where it is critical. “The tungsten topic comes up in almost every vendor conversation,” said Mark Vena, CEO and principal analyst at SmartTech Research. “Tungsten is the metal nobody talks about until missiles, factories, and machine shops all need it at the same time,” Vena said, noting that it connects warfighting, manufacturing, electronics, aerospace, EVs, and everyday tools. Vena described the current situation as “one ugly supply chain knot” and said the tungsten crisis is a reminder that for all of AI’s and tech’s advancement, the economy is still dependent on physical materials. As with other situations involving rare earth materials in recent years, China looms large in the supply chain bottleneck. China is the dominant supplier, controlling as much as 80% of the world’s tungsten , though its production is on the decline. It clamped down on exports back in February 2025, citing national security concerns, and it continues to subject the metal to tight export controls . According to the most recent USGS data , global tungsten production reached approximately 81,000 metric tons in 2024, with Vietnam a distant second to China. The U.S. produces virtually none domestically. Tungsten mining by country Metric tons produced in 2024 China and Vietnam account for more than 80% of the world's tungsten production.
