Revenue model

1. Defence Systems Sales: EID generates revenue through the design, manufacture, and supply of advanced communication and C4I solutions to military and defence customers. Revenue comes from large contracts with navies and armies for integrated communications systems, including the recent €42.3m contract for Portuguese Navy and £36.6m contract for naval communications systems.
2. Service & Support / Through-Life Support: EID provides ongoing maintenance, upgrades, repairs, training, and ILS (Integrated Logistic Support) services to customers. Services include predictive maintenance, corrective maintenance, obsolescence management, helpdesk support, and contract management. This creates recurring revenue opportunities throughout the lifecycle of installed systems.
3. Systems Integration: Revenue from systems engineering and integration services, including system design, deployment, commissioning, and training for naval and land communications systems.

Broad incumbents

• L3Harris Technologies: US-headquartered defence prime and a global leader in tactical communications, including Falcon-series radios and integrated naval/land C4I. Competes with EID on tactical radio and military messaging procurements worldwide.
• Thales: Global defence prime with deep naval communications and C4I offerings (including integrated communications systems for warships). Thales is a direct competitor for large naval platform bids and a benchmark for EID's addressable market.
• Kongsberg Gruppen: Norwegian defence and maritime technology group with a significant naval communications and combat systems franchise. Targets the same European and NATO-aligned naval customers as EID.
• Leonardo S.p.A. Italian defence and aerospace prime with a strong portfolio in naval communications, tactical radios, and military messaging. Operates as both a competitor (naval C4I) and a potential consortium partner on EU programmes.
• Elbit Systems: Israeli defence electronics house with comparable C4I, tactical radio, and integrated naval/land communications offerings, including ELSAT and TORCH-X products. Competes in similar geographies (Europe, Asia, Latin America) for tactical communications contracts.
• Saab AB: Swedish defence prime with a strong naval communications and 9LV combat management system portfolio. Competes directly with EID for naval C4I upgrades in European and export markets.

Others

• Chess Dynamics (Cohort plc sister company): Cohort plc sister company providing surveillance, tracking and fire-control systems. Not a direct competitor but a sibling within the parent group, useful as a benchmark for cross-sell potential and Cohort portfolio strategy.
