Brazilian protein group Marfrig surprised the market yesterday (15 January) with the announcement CEO Sergio Rial will stand down. Rial was a chief architect behind Marfrig's "focus to win" strategy, which has left the group on the cusp of a return to earnings stability. With internal successor Martin Secco Arias to replace Rial, the company was keen to emphasise coherence as it calmed initial investor jitters. Katy Askew reports.
