Sole Bookrunner Lucid Capital Markets Prospectus dated March16, 2026 DearProspective Stockholders, The global defense landscape is undergoing a profound transformation. Advances in artificialintelligence, autonomous systems and low-cost unmanned platforms are reshaping how modern conflicts arefought, shifting the center of gravity from hardware alone to the intelligence, coordination and software thatenable systems to operate effectively at scale. It is against this backdrop that I am honored to serve as non-Executive Chairman of Swarmer. Over the course of my career, I have worked at the intersection of national security, emergingtechnology and operational execution. As I have built and scaled defense-focused organizations, my workhas consistently centered on identifying technologies with the potential to meaningfully change outcomes,not in theory, but in real-world conditions. I have evaluated countless innovations that appeared compellingin test environments yet failed under operational pressure. Public-market investors are rightly skeptical ofunproven claims. I share their skepticism. It is precisely why Swarmer stood out to me. Swarmer is a software-first defense technology company focused on collaborative autonomy andintelligent swarming, originating from the cauldron of modern combat in Ukraine. To be clear, Swarmer isnot a drone manufacturer and is not dependent on any single platform, supplier, or hardware lifecycle.Instead, Swarmer operates at the intelligence layer, developing autonomy, coordination and decision-makingsoftware that enables large numbers of low-cost unmanned systems to operate together as a coherent,resilient force. Everything Swarmer develops is rigorously tested where it matters most: outside the wire, inkinetic operational environments. What differentiates Swarmer is not only its architecture, but the depth of operational data informing it.Since April2024, Swarmer’s platform has been deployed in Ukraine with more than 100,000 real-worldmissions in active combat environments, informing the software and machine-learning models that feed intoit. These missions generate continuous streams of telemetry, sensor data and operational feedback, whichare used to refine performance, increase resilience and accelerate learning. This cycle — deploy, observe,adapt and improve — creates a compounding advantage that cannot be replicated in laboratories orsimulations. The result is a battle-tested asset that acts as a force multiplier, allowing one operator to controlmany hardware platforms in real time.
