Ola Rollén

In 2016, Rollén was accused of insider trading in Norway for buying shares in Next Biometrics in October 2015 on behalf of Greenbridge Partners, a transaction which did not involve Hexagon. He was prosecuted by the Norwegian economic crime authority (Økokrim) and acquitted by The Oslo City Court in a unanimous verdict announced 10 January 2018. Following Økokrim's appeal of the acquittal, Rollén was acquitted for a second time, this time by the Borgarting Court of Appeal (Borgarting lagmannsrett), rejecting all charges of insider trading. The second acquittal verdict was announced 26 June 2019. The prosecutor in the case stated that they will not challenge the verdict, making the acquittal final.

In 2015, Rollén sold half of his shares in Hexagon to form the investment company Greenbridge Partners, which as of October 2015 owned 20% of Norwegian Next Biometrics. Melker Schörling, then chairman of Hexagon's Board of Directors, supported and invested in this new venture.

Hexagon also managed to create a successful Rubber compounding business Hexpol that was distributed to Hexagons shareholders in 2008 via an IPO on the Stockholm Stock Exchange.

In 1996, Ola Rollén became president of Kanthal. Two years later he changed jobs and became vice president at Avesta Sheffield. In 1999, he became CEO of Sandvik Stål (now Sandvik Materials Technology) in Sandviken.

After graduation, Rollén began his  career at Stora AB in 1989 and later joined AB Kanthal in 1990.

Rollén was born in Stockholm in 1965. He earned an undergraduate degree in finance and economics from Stockholm University in 1989.
