Ukrainian-American company Swarmer has agreed to acquire Ratel Robotics, a Ukrainian manufacturer of unmanned ground vehicles. Ratel founder Taras Ostapchuk has revealed details of the negotiations, the company's funding structure and its international expansion plans.
Defense technology company Swarmer (Nasdaq: SWMR) has signed an agreement to acquire Ukrainian unmanned ground vehicle (UGV) manufacturer Ratel Robotics. The transaction has a maximum potential value of $224 million, making it one of the largest publicly announced M&A deals in Ukraine's DefenceTech sector.
The agreement was first reported on September 10, 2026. Subsequently, in an October 26 interview with Forbes Ukraine, Ratel Robotics founder and CEO Taras Ostapchuk discussed the rationale behind the sale, competing acquisition offers, investment raised by the company and opportunities for expansion into NATO markets.
Deal Terms: $224 Million Represents the Maximum Potential Value, Not a Guaranteed Payment
According to Swarmer's filings with the U.S. Securities and Exchange Commission (SEC), the transaction combines an upfront cash payment, shares in the acquiring company and additional consideration contingent on Ratel Robotics' financial performance.
Upon the legal closing of the transaction, the sellers will receive approximately $7.2 million in cash, subject to contractual adjustments, along with 1.065 million Swarmer shares.
An additional cash payment of up to $7.2 million and up to 4.422 million shares may be awarded under an earn-out mechanism if the company meets specified revenue and operating profit targets during 2026–2028.
The financial targets associated with these contingent payments include:
| Year | Revenue | Operating Profit |
|---|---|---|
| 2026 | $77 million | $8.47 million |
| 2027 | $130 million | $14.3 million |
| 2028 | $187 million | $20.57 million |
An additional bonus for 2028 is available if the company achieves revenue of $249 million and operating profit of $27.39 million.
Therefore, the announced $224 million is not a fixed acquisition price. The ultimate consideration will depend on the achievement of financial targets and the market value of Swarmer shares.
Notably, Swarmer's stock has experienced significant volatility since the company's March 2026 Nasdaq IPO, which raised $15 million. According to Forbes, as of October 23, its shares were trading at $8.82, almost ten times below their June peak.
Why Ratel Chose Swarmer: Several Other Buyers Were Interested
According to Taras Ostapchuk, negotiations with Swarmer lasted approximately four months, with the due diligence process accounting for more than three months.
However, Swarmer was not the only potential buyer of Ratel Robotics. During the same period, the company received attractive acquisition offers from Ukrainian, Danish and American businesses.
A decisive factor in selecting Swarmer was that it approached Ratel first, approximately one to two weeks ahead of the other potential buyers.
Ostapchuk believes the combination will provide Ratel with access to additional investment in Ukraine and accelerate its research and development (R&D) activities.
Following completion of the acquisition, Ratel Robotics' Ukrainian legal entity will continue operating with a considerable degree of operational autonomy. Ostapchuk will remain CEO and retain responsibility for developing the business in Ukraine.
For Swarmer, the acquisition's strategic value lies in gaining access to combat-proven ground platforms, manufacturing capabilities, Ratel's engineering expertise and its partnerships with international defense companies.
From $2.27 Million in Initial Investment to a Deal Worth Hundreds of Millions
Ratel Robotics was founded in 2023. According to Ostapchuk, initial investment in the company totaled approximately $2.27 million, comprising $270,000 of his own capital and a further $2 million contributed by a partner.
Ostapchuk owns 50% of the company, while the remaining equity is held by three other shareholders.
During its early development, Ratel also received grant funding from Brave1, which helped finance technology development and the launch of production.
The company started with a team of four people and had expanded to approximately 400 employees by October 2026.
According to Swarmer, Ratel Robotics secured contracts totaling $86 million in 2026. The company has become one of Ukraine's leading manufacturers of unmanned ground vehicles for logistics, evacuation and other military applications.
Previously disclosed figures indicate that, during the first four months of 2026, Ratel secured orders equivalent to approximately 37% of the Ukrainian Ministry of Defense's procurement budget for unmanned ground systems.
New Investments: Autonomous Systems and Unmanned Aerial Vehicles
One of Ratel Robotics' key development priorities following its combination with Swarmer will be the creation of integrated autonomous systems capable of coordinating unmanned ground and aerial vehicles.
Swarmer specializes in software for the autonomous control and coordination of multiple drones. According to the company, its technology has been deployed in more than 100,000 combat missions in Ukraine since April 2024.
Ratel is developing its own software solutions, including autonomous navigation and mission execution capabilities. The two companies intend to integrate their technologies into a unified ecosystem.
In March 2026, Ratel launched its unmanned aerial vehicle (UAV) manufacturing division. According to Ostapchuk, initial investment in this segment amounted to approximately $200,000.
Looking ahead, the company plans to invest several million additional dollars in developing fixed-wing UAVs, which are technologically more sophisticated than its current multirotor systems.
At the same time, Ratel aims to strengthen its in-house manufacturing and engineering capabilities to reduce dependence on external contractors.
International Expansion: NATO, General Dynamics and New Partnerships
Expansion into international markets, particularly NATO countries, is one of Ratel Robotics' key growth priorities.
The company has already reached a joint manufacturing agreement with U.S. defense corporation General Dynamics in Canada.
In addition, Ratel is preparing to sign a memorandum of understanding on joint production in another NATO country and plans to hold negotiations with two additional industrial partners.
Its international expansion strategy includes potential production localization as well as supplying robotic systems to the armed forces of other countries.
Ratel Robotics identifies Estonia's Milrem Robotics, Germany's ARX Robotics and Quantum Systems, along with major defense contractors, among its main international competitors.
One of the Ukrainian manufacturer's key advantages is its competitive production cost. According to Ostapchuk, Ratel M unmanned ground vehicles are approximately five times less expensive than comparable ARX Robotics systems.
At the same time, the founder emphasizes that Ukrainian companies will need substantially greater investment in technology and research to compete effectively with Western manufacturers.
Consolidation in Ukraine's DefenceTech Sector Is Gaining Momentum
The acquisition of Ratel Robotics reflects a broader consolidation trend in Ukraine's defense technology market, which includes hundreds of unmanned systems manufacturers.
Previously, Ukrainian company Vyriy Industries acquired controlling stakes in five defense companies, while U.S.-based MITS Capital consolidated several Ukrainian DefenceTech businesses under MITS Industries.
Swarmer Chairman Erik Prince, the founder of Blackwater, has also expressed the company's intention to pursue further acquisitions and partnerships with developers and manufacturers of combat-proven technologies.
For Ukraine's DefenceTech sector, the Swarmer–Ratel Robotics transaction demonstrates the potential of international M&A as a means of scaling manufacturing operations, attracting capital and expanding into global defense markets.
At the same time, the transaction's structure indicates that buyers are increasingly linking the valuations of defense technology companies to future financial performance rather than relying solely on existing technologies or current order backlogs.
