EOS acquisition of MARSS marks successful exit for Graphene Ventures

Counter-drone deal strengthens EOS’s systems capability and advances the next phase of growth for MARSS.

Electro Optic Systems Holdings (EOS) has agreed to acquire MARSS, a European provider of counter-drone command-and-control technology, in a transaction that delivers a successful exit for Graphene Ventures.

The deal, announced on January 12, will see EOS acquire the MARSS business, including its proprietary NiDAR command-and-control (C2) platform, related software and hardware, customer contracts, and intellectual property. Financial terms include an upfront cash payment of US$36 million, with the potential for earnout payments of up to €100 million linked to future contract performance.

Founded in 2006, MARSS develops AI-enabled sensor fusion and C2 systems designed to detect, identify, decide, and defeat unmanned aerial threats. Its NiDAR platform integrates multiple sensors and effectors into a single decision-making architecture, allowing for rapid and coordinated responses to asymmetric drone threats across military, homeland security, and civil infrastructure environments.

For EOS, the acquisition represents a strategic shift from a component-focused supplier toward a fully integrated counter-drone systems provider. By combining MARSS’s software and AI capabilities with its own sensor and effector technologies, EOS aims to deliver end-to-end counter-UAS solutions, including turnkey systems for the protection of critical infrastructure such as airports, power plants, and military assets.

The transaction also expands EOS’s geographic footprint and strengthens its presence across defense and security markets. EOS plans to integrate NiDAR into its existing remote weapon systems, enabling mesh-networked coverage capable of providing hemispherical protection against drone threats.

The acquisition is structured as an asset purchase and will be funded primarily from EOS’s existing cash reserves. The company said the transaction is expected to be broadly neutral to earnings and operating cash flow in 2026. Completion remains subject to regulatory and customer approvals.
