Summa Defence has reshaped its management team during a formative year for the young defence-technology group. Two senior executives—COO Tommi Malinen and CCO Tommi Manninen—resigned this week, according to the company’s press release. As a result, interim CEO Timo Huttunen will also assume COO duties, while communications responsibilities shift under the CFO.

The changes come only months after the merger between Summa Defence Oy and Meriaura Group, completed in June, which created the current Summa Defence entity. The combined group now focuses on dual-use technologies through subsidiaries active in drones, maritime platforms, and industrial systems. Governance has also evolved quickly: according to Listeds data, three of the company’s four board members, including chairman Arto Räty, took up their roles this year.

Earlier this month, the board appointed Huttunen as interim CEO after a mutual decision for Jussi Holopainen to step down and concentrate on new technologies, including drones, Lightspace, and space technology. Chairman Räty explained the board’s reasoning: “Timo Huttunen, with his deep knowledge of Summa Defence, is a natural choice to take responsibility for leading the company on an interim basis until a new CEO is appointed.”

Huttunen previously served as CEO of the subsidiary Aquamec and has more than a decade of experience from listed companies, including Cargotec and Lännen MCE Group, whose former subsidiaries now contribute roughly half of Summa Defence’s revenue.

The management reshuffle follows the company’s January–September business review, where Holopainen described continued efforts to build the organisation: “In the third quarter, we continued our determined work to build and strengthen the Group for our future plans.” 

Despite merger-related expenses and weak performance in renewable energy, pro forma net sales rose 47 percent year on year to EUR 65.3 million for January–September. The company maintains full-year guidance of EUR 90–110 million and has begun exploring the possibility of transferring its shares to the main lists of Nasdaq Helsinki and Stockholm during 2026.
