SIG appoints Ann-Kristin Erkens CEO as Mikko Keto exits after six months

SWITZERLAND – SIG has appointed Ann-Kristin Erkens as its new Chief Executive Officer, replacing Mikko Keto who took the role on 1 March 2026, with Erkens bringing deep operational and financial expertise from her previous roles as CFO and interim CEO.

Erkens joined SIG as Chief Financial Officer in November 2023 and served as interim CEO from August 2025 to February 2026, and will continue in her CFO role until a replacement is appointed. 

Before joining SIG, she spent more than 20 years at Henkel in senior positions, including Corporate Senior Vice President and Head of Global Supply Chain for the Adhesive Technologies business. 

The leadership change coincides with SIG’s half-year results showing a 7 percent sales increase and a 15.6 percent adjusted EBIT margin, up from 14.8 percent a year earlier, with free cash flow increasing by more than €100 million (US$115.8 million). 

CEO’s Priorities and Strategic Focus

Erkens stated that SIG has a strong business, leading technology and long-standing customer relationships, with clear priorities to focus resources on areas where the company can grow to create value for customers and shareholders, improve operational performance, and maintain strict cost and capital discipline. 

SIG Chair Ola Rollén thanked Keto for his contribution and commitment to the company, noting that Erkens knows SIG very well and has played a central role in shaping the performance improvement roadmap. 

Rollén added that Erkens is ideally placed to ensure continuity and drive the next phase of SIG’s development. 

The company’s Capital Markets Day will go ahead as scheduled on 27 October 2026 at The Circle Convention Center at Zurich Airport.

Recent Performance and Transformation Programme

SIG’s full-year 2026 financial guidance, restated in the first-half 2026 earnings release, has not changed, with the company maintaining a cautious outlook driven by geopolitical uncertainties. 

Last year, SIG launched a transformation programme to focus on “higher-margin, higher-growth” aseptic businesses, divest smaller non-aseptic units, and boost operational efficiency, with Erkens playing a central role in shaping the performance improvement roadmap. 

In the second half of 2025, SIG made significant leadership changes, including the departure of CEO Samuel Sigrist. Keto previously served as President of SIG’s China and Southeast Asia region, where he led the company’s aseptic packaging business and drove strategic expansion and commercial partnerships.
