The thesis
Why this org is unusual
Post Holdings’ most distinctive structural feature is that its public-company CEO directly oversees multiple operating-company CEOs rather than running a tightly centralized functional enterprise.
The chart shows the CEO with a broad span of control that includes the CEO of Post Consumer Brands alongside core functional leaders like the CFO, COO, General Counsel and HR head. This reflects Post’s holding-company orientation, where operating businesses retain significant autonomy.
