WISA Group Plc Appoints New CFO as Demerger Approaches

The Finnish Financial Supervisory Authority (FFSA) has recently given the green light for important adjustments to WISA Group Plc's documentation associated with its upcoming demerger. This approval, dated September 18, 2026, reinforces the leadership structure within WISA as it prepares for a new chapter following its partial demerger from UPM-Kymmene Corporation.

Changes in Leadership

In a significant move, Lasse von Hertzen has been appointed as the Chief Financial Officer (CFO) of WISA Group Plc. His appointment marks a crucial step in the company’s transition, especially since he had previously served as the interim CFO. This leadership change reflects WISA’s commitment to maintaining strong financial oversight as it navigates the complexities of becoming an independent entity.

The Board of Directors at UPM-Kymmene Corporation announced this transition while detailing the composition of WISA’s Group Leadership Team. Besides von Hertzen, the team includes:

• - Tuija Suur-Hamari - President and CEO
• - Pia Helminen - Senior Vice President, HR
• - Saara-Maria Helminen - Senior Vice President, General Counsel
• - Kristiina Jaaranen - Senior Vice President, Marketing, Sustainability and Communications
• - Susanna Rinne - Senior Vice President, Sales
• - Juhani Tenhunen - Senior Vice President, Operations

These appointments are set to become effective concurrent with the completion of the demerger scheduled for October 31, 2026. The operational leadership team will continue their current roles at UPM until WISA officially separates from the parent company, ensuring a smooth transition.

Demerger and Future Plans

WISA Group Plc is gearing up for its shares to commence trading on the Nasdaq Helsinki Ltd by November 2, 2026. This scheduled public trading represents a significant milestone for the company, providing it with greater autonomy and opportunities to redefine its market strategies. The planned demerger is expected to enable WISA to enhance its core business operations focused on renewable materials and sustainability solutions.

The FFSA has approved a supplement to the Finnish language demerger and listing prospectus related to the strategic separation from UPM. WISA is positioned to leverage this change, aimed at boosting operational efficiency while advancing its objectives in sustainability and material solutions.

UPM's Commitment to Sustainability

As a global leader in material solutions, UPM-Kymmene operates with a focus on sustainability, offering an extensive range of renewable fibers and advanced materials while also emphasizing decarbonization. The company has gained recognition from third parties such as EcoVadis for its sustainability practices, underlining its commitment to ethical and environmentally friendly operations.

As WISA prepares for its new path, the backing of UPM-Kymmene and its established reputation will serve as a strong foundation. With a projected annual revenue of approximately €9.7 billion and a workforce of around 15,100, UPM’s influence on WISA’s initial growth phase will be invaluable.

Conclusion

The appointment of Lasse von Hertzen as CFO is a pivotal development for WISA Group Plc as it strides towards independence. With the upcoming demerger, the company aims to strengthen its position within the market while fostering a robust leadership structure that reflects its dedication to sustainability. Stakeholders and investors will be eagerly watching to see how WISA capitalizes on this transformation, setting the stage for future growth and success.
