With the expiration of its 2018-2020 targets, and the introduction of segment reporting, Better Collective's board of directors has decided on new financial targets for 2021, including generating over €160m in revenue, over €50m in EBITDA (rather than EBIT before special items) and organic growth of over 20%.
Jesper Søgaard, Better Collective CEO, said: "Looking back at an unusual year, I am pleased to see our business has proven resilient and I am proud we came out strong on performance.
"We have entered 2021 in great shape and are well-positioned for an eventful 2021."
