General Counsel Hanna Kyrki will leave Summa Defence Plc by 13 November 2026, ending a nine-month tenure that began shortly after the Finnish defence and security technology group was formed through its merger with Meriaura Group.
Her departure follows a six-week stretch of executive turnover at the Nasdaq First North Growth Market-listed company. Robert Blumberg assumed the role of CEO on 13 April alongside new CFO Petter Ruda, while Interim CEO Timo Huttunen stepped down from the position.
Summa Defence said Kyrki is leaving for personal reasons and that her responsibilities will be absorbed by the existing management team rather than assigned to a direct replacement, the company announced on 13 May.
Defence-sector legal experience exits during integration phase
Kyrki joined Summa Defence’s executive management team on 4 August 2025, weeks after the merger between Meriaura and Summa Defence closed. Her background brought deep defence-sector governance experience to the newly assembled company. Before Veikkaus, she served as general counsel, chief compliance officer, and executive management team member at Finnish defence company Patria. Earlier roles at Nokia, Tellabs, Sonera, and Kone gave her experience across telecoms, technology, and industrial engineering.
The timing adds further pressure to a company still integrating multiple corporate transformations. On the same day it disclosed Kyrki’s departure, Summa Defence warned that its current working capital is expected to be sufficient for only around two months without additional financing arrangements. The company estimated it will require EUR 10–20 million in additional funding over the next 12 months. Following the Ascension Day market holiday, shares fell 36.8% to EUR 0.80 this afternoon, underscoring investor concern over the company’s liquidity position.
Against that backdrop, the decision not to immediately recruit a successor suggests management is keeping a close watch on costs while the post-merger organization stabilizes.
Leadership rebuild continues under new CEO
Blumberg acknowledged Kyrki’s role in the company’s formative post-merger period. “We thank Hanna for her contribution to the development of Summa Defence Plc and wish her all the best for the future,” CEO Robert Blumberg said in the company statement.
The sequence of changes amounts to the most substantial leadership reset since Summa Defence’s creation in 2025. What follows now is execution: a new CEO, a recently appointed CFO, and an organization still building governance structures after successive mergers.
Whether the company appoints a new general counsel before Kyrki’s departure in November will be an early signal of how aggressively it intends to build out its permanent executive bench.
