Ann-Kristin Erkens, who previously led the programme as interim CEO from August 2025 to end of February 2026 and delivered strong results, is now being made permanent CEO. She will also continue to serve as CFO until a successor in this role has been appointed. She replaces interim CEO Mikko Keto, who joined packaging giant SIG as CEO in spring of 2026 and worked with the leadership team to further develop the company’s transformation agenda, the company says. 

SIG has made good progress in the first half of 2026, improving its adjusted EBIT margin to 15.6% (compared with 14.8% in the prior-year period), while free cash flow improved by more than €100 million year-on-year. SIG has also continued to strengthen operational efficiency and cost discipline and to sharpen its focus on aseptic system solutions. 

Ola Rollén, chair of SIG, says, “Mikko joined SIG at an important point in the company’s development and has contributed to the progress made over the recent months. I would like to thank him for his commitment to SIG and wish him all the best for the future. We are very pleased that Ann-Kristin has agreed to take on the role of CEO. She knows SIG very well, has played a central role in shaping our performance improvement roadmap and has already successfully led the Company as interim CEO. She brings strong leadership as well as deep operational and financial expertise and is ideally placed to ensure continuity and drive the next phase of SIG’s development.” 

Prior to joining SIG, Erkens held senior financial, operational and strategic roles during more than 20 years at Henkel.
