Definition
Entering unrelated businesses primarily for portfolio balance and capital allocation advantages rather than direct capability overlap.

Introduction
Conglomerates can create value when corporate HQ allocates capital better than markets, shares superior management systems, or builds internal markets for talent and know-how.

Explanation

Value creation levers

Superior capital allocation, governance, procurement scale, shared services, risk smoothing.

Perils

Empire building, complexity costs, valuation discounts (conglomerate discount).

Design

Clear investment criteria, decentralization with accountability, rigorous divestitures, CEO market for BU heads.

When it works

Underdeveloped capital markets, operational excellence playbooks, or unique corporate platforms (data, logistics).

Key Takeaways

The system at HQ must be a capability—else the discount persists.

Be ruthless about entry & exit.

Transparency and incentives keep complexity in check.
