Betsson chief financial officer Kaaren Hilsen has tendered her resignation after less than one year in the role.

The Stockholm-listed gaming operator said Tuesday that Hilsen will leave the company to assume the chief executive’s office at Norwegian telecoms group Telenor in Sweden, subject to a six-month notice period.

Hilsen joined Betsson as CFO in October 2017, replacing former CFO Fredrik Rüdén who left in August of that year.

“I would like to thank Kaaren for her contribution in getting Betsson back on track,” said Betsson chief executive Pontus Lindwall.

“I respect that she has received an offer she couldn’t refuse and wish her all the best for the future. Betsson is a stronger company than it was a year ago and I am sure that we will soon recruit a new CFO who wants to be part of taking Betsson to the next level.”

Hilsen previously served as CFO of Telenor in Sweden and will return to the company as chief executive.

Shares in Betsson AB (STO:BETS-B) were trading down 1.21 per cent at SEK70.26 per share in Stockholm early Tuesday morning.
