Danske Spil said that Mehl has secured a new role as chief executive of an unnamed technology company, but will remain in her current role until 1 November 2021 at the latest.
The operator said that during her time as director, Mehl has made significant changes and helped to modernise the business.
“Pernille, together with her team and in collaboration across Danske Spil, has delivered an incredibly good effort and impressive results in DLO, which means that today we have very strong and competitive brands within our games,” said Nikolas Lyhne-Knudsen, administrative director of Danske Spil.
“I would therefore like to take this opportunity to say a thousand thanks to Pernille and offer congratulations. I am glad that Pernille has plenty of time to follow tasks through to the end and say a proper goodbye in the autumn.”
Commenting on the announcement, Mehl said: “I have enjoyed every single day in Danske Spil, so it is with sadness that I have to say goodbye.
“I feel proud and lucky to have been surrounded by such competent colleagues ,who together have helped to create a strong business.”
Last week, Danske Spil warned of illegal “lottery subscriptions” that were circulating in regions of Denmark.
