Swarmer Publishes Letter From Its Chairman, Erik Prince, Outlining Strategy
AUSTIN, Texas, June 11, 2026 (GLOBE NEWSWIRE) -- Swarmer, Inc (“Swarmer”) (NASDAQ: SWMR), a drone autonomy software company which has supported more than 100,000 real-world combat missions in Ukraine since April 2024, today issued a letter from its Chairman, Erik Prince.
Dear Shareholders,
I am writing this letter after returning from five days on the ground in Ukraine, where I visited some of the most innovative defense technology companies operating anywhere in the world today. These are not companies building to a specification or a procurement cycle. They are building to survive testing their assumptions daily against real adversaries, iterating in hours rather than years, and producing results that are redefining what effective defense looks like. That experience deepened my conviction in everything that follows.
The broader geopolitical backdrop has never made this mission more urgent. As the United States moves to seize and redirect billions in frozen Iranian assets and as conflicts from Eastern Europe to the Gulf continue to accelerate demand for sovereign, affordable defense capability, the window for companies like Swarmer to establish themselves as the platform of record for battlefield-proven technology is opening fast.
Since becoming Chairman of Swarmer, I have become increasingly convinced that the company’s opportunity extends well beyond its current software platform. While Swarmer’s autonomy and battlefield management technologies remain at the core of our business, our broader objective is to build a platform company that can identify, acquire, partner with, and help scale innovative defense and security technology companies whose products have been battlefield tested and proven effective under demanding operational conditions.
Many also face a strategic dilemma. While their businesses may be experiencing strong momentum today, they recognize that when the war ends, demand within Ukraine could change significantly, creating concentration and market risk. By providing capital, strategic support, access to international customers, and a pathway into new markets, we believe Swarmer can help these entrepreneurs diversify their businesses beyond a single geography. In turn, this can give founders greater confidence to continue investing, hiring, and innovating within Ukraine today, knowing they have a credible path toward long-term global growth.
Importantly, many of these discussions are not new. We continue to build a pipeline of potential acquisitions, partnerships, and strategic relationships that we believe can accelerate growth and create long-term shareholder value. We are currently seeing strong momentum with several of these opportunities and, while there can be no assurance that any particular transaction will be completed, we hope to provide shareholders with additional color on our progress in the coming weeks. To support this objective, we recently filed a Form S-1 to register the resale of up to 3 million shares of common stock. There are three important points I would like to emphasize:
First, this filing simply registers for resale shares that the Board may elect to sell to a single investor over time pursuant to an equity facility. It is not a single offering, and no decision has been made regarding the timing, amount, or pace of any future sales. This instrument provides flexibility should attractive opportunities emerge.
Second, the structure allows shares to be sold at prevailing market prices, subject to a modest 2% discount. We believe this represents one of the lowest-cost sources of growth capital available to the company while allowing us to raise funds responsibly and opportunistically rather than through a large, dilutive financing.
Third, access to capital matters. The defense technology landscape is evolving rapidly, and we believe attractive acquisition, investment, and partnership opportunities may become available as entrepreneurs seek strategic partners capable of helping them expand internationally. Having the ability to move quickly can be a significant competitive advantage.
Our goal is to position Swarmer not only as a developer of world-class software, but as a broader platform capable of identifying, scaling, and commercializing proven defense technologies for customers worldwide.
We remain focused on disciplined execution, prudent capital allocation, and building long-term value for our shareholders.
Thank you for your continued support.
Erik Prince

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.
