John Mattson appoints new CFO

John Mattson has appointed Ebba Pilo Karth as the company’s new CFO. She will assume her role by 1 April 2024 at the latest and will also join company management at that time. Until that time, Eva Wiklund will hold the role of interim CFO. In August 2023, Maria Wirén assumed the role of Head of Property Management and is now a member of John Mattson’s company management.

The incoming CFO, Ebba Pilo Karth, joins us most recently from Forsen AB, where she has held the role of CFO since 2021. Prior to that, she held the roles of Chief Financial Officer of Stena Fastigheter Stockholm AB and as CFO of Telia-owned Skanova AB.

“I very much look forward to welcoming Ebba as the new CFO of John Mattson. Ebba has broad experience from working in various financial roles both in the property industry as well as in other industries. Her experience of accounting and operational and business-related positions means that Ebba will be a considerable asset to the company’s continued development,” says Per Nilsson, CEO of John Mattson.

“I am impressed by John Mattson’s innovative and proactive approach and look forward to utilising my experience to further strengthen the company’s financial and operational positions. I feel incredibly inspired by the opportunity to join this dedicated team and make a real difference,” says Ebba Pilo Karth.

Maria Wirén, who previously held the position of Head of Property Management Residential and who was co-opted to company management, took over the position as Head of Property Management and joined as a regular member of company management on 1 August.

“In the past year, Maria has held a central role in the company’s rapid transition in which we have streamlined the efficiency of property management while concurrently raising customer and employee satisfaction. It is therefore gratifying that Maria is assuming overall responsibility for property management with responsibility for residential and commercial premises alike. We are maintaining our focus on both property categories with managers for the respective areas. I would like to extend Maria a warm welcome in her new role and as a regular member of company management,” says Per Nilsson, CEO.

John Mattson’s company management comprises: Per Nilsson, CEO; Mari Edberg, Head of Communications; Daniel Fornbrandt, Head of Business and Project Development; Maria Wirén, Head of Property Management; and Eva Wiklund, interim CFO. Eva Wiklund will be replaced as CFO by Ebba Pilo Karth by 1 April 2024 at the latest.
