[8] On December 23, 2014, Oerlikon announced that it had reached an agreement on the sale of its Advanced Technologies Segment to the Swiss company Evatec AG.

[9] In July 2018, Oerlikon announced that it had signed a definite agreement for the sale of its Drive Systems Segment to Dana Inc.[10] The transaction was closed on February 28, 2019.

[11] The ownership structure of OC Oerlikon has gone through numerous drastic changes over the years, partly due to some large options transactions.

Oerlikon's Annual Report 2021 gives the shareholder structure as follows:[12] The board of directors is responsible for the supervision and strategic management of the company.

At Oerlikon's 42nd Annual General Meeting of Shareholders, Michael Suess was appointed chairman of the board of directors.

In May 2004, Thomas Limberger was appointed to the board of directors; in June 2005, at the request of the majority shareholder, Victory Industriebeteiligung, he was named CEO of Unaxis as the company was known at the time.

Under Limberger, two further roles were added to the executive committee in February 2007: General Counsel (filled by Bjoern Bajan), and COO (Uwe Krüger).

Limberger stayed with the company until May 2007, when he resigned as CEO and from the board of directors and joined Von Roll Holding.

Upon his resignation, Limberger was replaced as CEO by Uwe Krüger, whose previous position as COO remained vacant until September 2008, when it was filled by Thomas Babacan.

The post of Chief Operating Officer that had been left vacant following the departure of Thomas Babacan on December 31, 2011, was not occupied again.

He was replaced as CEO on an interim basis by CFO Jürg Fedier, who at that time was the only member of the executive committee.

[15] Brice Koch took up the position of CEO of OC Oerlikon in January 2014, allowing Jürg Fedier to focus on his original role as CFO.

[16] In March 2016, Oerlikon announced former Siemens AG manager Roland Fischer would replace Brice Koch as CEO.

[17] With the publication of the 2021 annual results in March 2022, OC Oerlikon announced that Roland Fischer was stepping down as CEO for private reasons, and that Michael Süss will assume the executive chair role.

Toward the end of that year, it sold Pilatus Flugzeugwerke AG – the last company that did not fit in with the rest of Unaxis' technology portfolio.

Poor performance in FY 2004 from the semiconductor division of Esec meant losses of CHF 372 million for Unaxis and a slump in its share price.

In June 2005, Unaxis' new majority shareholder, the Austrian firm Victory Industriebeteiligung AG, called an extraordinary general meeting where it replaced virtually all of the group's management team.

This was due to negative reporting in the media and the subsequent surprise intervention of Victory Industriebeteiligung and OC Oerlikon, at that time only a few days old.

In the course of this reorganization process, the Segment's upper management was gradually relocated to Shanghai, and hence to the world's largest textile market.

[25] In July 2018, Oerlikon announced that it was selling its Drive Systems Segment to Dana Inc.[26] The sale was finalized on February 28, 2019.
