On October 1st, 2005, Aarhus United from Denmark and Karlshamns AB from Sweden merged to form AarhusKarlshamn—today known globally as AAK. As we approach our 20th anniversary, we reflect on a strategic union that combined over a century of expertise in plant-based oils and fats—laying the groundwork for what is now a global leader in customized and sustainable fat solutions.

A merger for Making Better Happen 
The merger was more than a consolidation—it was a vision for synergy. Aarhus United, founded in 1871, had built a reputation for technical excellence and global reach. Karlshamns AB, established in 1918, was known for its innovation and sustainability. Together, they formed a company that could serve diverse markets with complementary strengths in production, R&D, and customer solutions. 

Since 2005, AAK has grown into a leading player in the speciality segment of the industry. One key factor behind the success has been the ability to adapt and evolve with the changing times, to keep the company at the forefront of innovation, constantly seeking new ways to improve  products and services. The commitment to quality and customer satisfaction has been the driving force behind the growth. 

Johan Westman, CEO and President of AAK, reflects: 
“As we celebrate this milestone, we honor the bold decision that brought Aarhus and Karlshamn together. From local roots to global impact, AAK has evolved into a purpose-driven company that continues to innovate, inspire, and make a better world happen. I want to extend my gratitude to everyone who has been part of the journey.” 

To mark this milestone, October 1st will be celebrated across the AAK organization—with cake, balloons, and moments of reflection on our shared journey.
