Michael Chaney is set to conclude his 11-year tenure as chair of Wesfarmers on 29 October 2026. Ken MacKenzie has been appointed to succeed him at the helm of the $85 billion Australian conglomerate.

Why it matters

Chaney's departure marks a transition for a firm that has reshaped its portfolio through strategic moves like the 2018 Coles spin-off and various acquisition attempts. The leadership change comes as Wesfarmers continues its focus on generating long-term shareholder returns through disciplined capital allocation.

Wesfarmers commands a market value of $85 billion, notably navigating a major transition after spinning off Coles in 2018 which removed 40 percent of its business. The company also maintains a significant workforce, having paid 100,000 employees throughout the pandemic.
