Summa Defence

What Summa Defence does

Summa Defence Oyj is a Finnish defence and security technology holding company that aggregates six operating subsidiaries under a Nasdaq First North Growth Market listing, organised around three focus areas: Maritime Technologies, Land Technologies, and New Technologies. The group serves NATO member-state governments, armed forces, coast guards, and security authorities, with a sales-led enterprise model relying on direct government tenders, framework agreements, and appointed dealer networks in markets such as Norway, Ukraine, and Germany. Cumulative deliveries to defence and security authorities stood at approximately €300 million as of mid-2025, and FY2025 revenue was guided at €90–110 million.

Core products include the Lännen 8800M-DF multipurpose machine (NATO NSN 2420-58-002-2440) built by Lännen Tractors, SWATH (Small Waterplane Area Twin Hull) aluminium personnel transfer vessels and offshore wind service vessels built by Uudenkaupungin Työvene at its Uusikaupunki and Olkiluoto shipyards, Zeus FPV drones from Summa Drones, helmet-mounted AR glasses (dG1800) from LightSpace Technologies, Watermaster amphibious environmental dredgers from Aquamec, and container/space module solutions from IntLog. The strategic positioning is dual-use: products with established civilian track records (offshore wind vessels, environmental dredgers, construction machines) are adapted for defence applications, enabling entry into NATO procurement while reducing dependence on any single end-market.

Revenue mechanics are dominated by one-time hardware sales and contract-based shipbuilding rather than recurring or subscription models. Pricing is not publicly disclosed and is negotiated bilaterally through defence tenders; the single largest disclosed contract is a €35M framework agreement with a European NATO member state for deliveries across 2026-2028. The corporate perimeter has been actively reshaped — the Olkiluoto shipyard was acquired in June 2025, LightSpace in December 2024, while non-core renewable energy subsidiary Rasol was divested in May 2026 for a nominal €5,000. As of June 2026 the group faces a working capital shortfall, an approximately 90% share price decline, a shareholder-mandated special audit of listing proceeds, and an entirely reconstituted board of directors — operational momentum against acute corporate-governance and liquidity stress.
