SIG

## SIG announces new CEO.

As part of the company’s long-term succession planning, Vervaat will transition into the role of Non-Executive Chair around 18 months later, after Andrew Allner steps down from the position and from the Board. This is because Allner will have served the full period he is allowed under UK governance rules. 

“The Board is delighted to announce that Pim has agreed to join SIG as its CEO and Non-Executive Chair designate,” said Allner. “He has significant experience in operating in decentralised European businesses and a strong track record of delivering shareholder value. The Board looks forward to working with Pim on SIG's growth and development.”
