He has other healthcare holdings too. He owns 15.6% of Ambu, another medical device company based just outside Copenhagen.

How Forbes has valued Niels Peter Louis-Hansen

Forbes put Louis-Hansen at $5.4 billion in 2019. His fortune then grew to $7.4 billion in 2020 and peaked at $8.2 billion in 2021, when healthcare stocks were in demand. It fell to $7.2 billion in 2022 and $5.8 billion in 2023, before rebounding to $7.4 billion in 2024.
