Summa Defence adjusts leadership as growth plans accelerate

Honkarakenne has appointed HR Director Sanna Hovila as Vice President, People and Communications and a member of the Executive Group from 9 October 2026. She reports to President and CEO Magnus Hindström, and the Executive Group now has six members.

“Sanna has strong expertise and insight in personnel matters and in developing our culture. As a member of the Executive Group, she will ensure that the employee perspective is included in decisions from the very beginning and that they are communicated clearly,” said Magnus Hindström, President and CEO.

Hindström brings people and communications to the top table two months into the job

Hindström took over on 3 August, succeeding Marko Saarelainen, who moved to lead subsidiary Honka Japan. He joined from Metsä Wood, where he was vice president for Kerto LVL sales. Hovila has been HR Director at Honkarakenne since 2021 and previously worked at Atria.

Through August, every incoming chief financial officer at a Helsinki issuer since December 2025 already held the title somewhere else. In September, Vincit promoted from its own controlling team and UPM made WISA's interim finance chief permanent. The lateral market did not close: Tieto and Relais both hired sitting finance chiefs, and Terveystalo is now searching for one.

Listeds had recorded at least ten CFO changes across Nasdaq Helsinki and First North between December 2025 and August 2026, and not one incoming finance chief was taking the job for the first time. Last month's roundup ended on whether September would break that run. It did, at the smaller end of the market.

The month's second signal was structural. Viking Line, Kalmar, Terveystalo and the planned UPM and Sappi graphic paper joint venture each redrew an organization in September and named the people to run it. Board-level change stayed thin, and most of it was nomination-board formation for the 2027 annual general meetings rather than turnover in the boardroom itself.

Vincit and WISA broke the lateral run with internal finance appointments

The Digia and Vincit chain that opened in August closed in September. Vincit named a successor on September 01, and went inside to do it. Paula Kuittinen, Head of Management Accounting and Business Control since March 2026 and before that more than 12 years in finance roles at CGI, most recently she has been the Finance Director, now becoming the CFO on November 1. "It is great to be able to appoint our new CFO from within the company," said chief executive Julius Manni.

On September 18, UPM's board appointed Lasse von Hertzen, previously WISA's interim CFO, its permanent Senior Vice President and Chief Financial Officer, effective when the plywood demerger completes. That finishes a WISA leadership team named in full by the parent's board, with trading expected from November 2.

LapWall took a third route. Tuomo Riihonen's employment ended on September 24, and the next day the company named Tiina Määttä Chief Financial Officer and Legal Officer from October 1. Her record runs through finance and legal advisory roles at Talenom and Greenstep and the chief executive seat at Kymsol Group.

Kempower named Lasse Hatinen on September 9, bringing more than 15 years of finance leadership in listed industrial companies. He joins by March 1, 2027 at the latest, from Metso where he has served as Senior Vice President, Group Controller. Juha Jaatinen, interim since August 13, holds the seat until then.

Larger issuers kept buying finance chiefs who already hold the title

The lateral market remains the default above small cap. Tieto appointed Juuso Pajunen from Terveystalo on September 16, and Terveystalo opened its search the same day. Relais Group appointed Joonas Mäkipeska on September 14 from Technopolis, where he is Chief Financial and Strategy Officer, after CFO roles at Holiday Club Resorts, Sponda and ALD Automotive. Chief executive Christian Gebauer framed the brief as "continued profitable growth, supported by financial discipline, strong cash conversion and investment discipline."

Stora Enso moved the other way on the same theme: on September 17 CFO Niclas Rosenlew was named deputy chief executive to President & CEO Hans Sohlström while keeping the finance role. Tallink appointed Armin Penner as its new CFO on September 8. He has worked for more than six years as CFO and Management Board Member of Circle K Eesti and has also served as CFO of Euroapteek and Ragn-Sells Eesti. 

SSH went outside for its chief executive, Arvo went to its own board

September's two listed-issuer CEO appointments took opposite routes. SSH Communications Security named Lars Bell from Omada, where he was Chief Customer Officer and interim chief executive, effective October 1. The share rose 49.5% in the five sessions to September 7. Bell inherits a business whose second-quarter revenue recovered to EUR 5.7 million, up 6.8%, while EBITDA fell 40.7%, and he starts on the same day as CFO Cristian Arias. The third-quarter report will be the first one a rebuilt executive team owns.

Arvo Sijoitusosuuskunta named Teemu Kokko, a member of its board of directors since 2021, deputy chief executive from December and chief executive from April 1, 2027. The selection ran through a nomination committee drawn from the cooperative's supervisory board, one level above the board Kokko sits on. He inherits first-half operating profit of EUR 8.5 million against EUR 6.5 million a year earlier, most of the step-up traced to an approximately EUR 6.9 million gain on the HANZA exit.
