Definition. A structure in which buyer and seller are deliberately locked into each other after closing — typically through captive revenue contracts — so that neither side can defect without destroying its own economics.
The Mechanism
In a corporate carve-out, the sponsor’s greatest fear is that the parent walks away with the customer base. The pattern solves this by making the parent the anchor customer under long-term captive contracts, while the parent remains operationally dependent on the carved-out unit’s service. Each side holds a hostage: the sponsor holds the parent’s operational continuity, the parent holds the sponsor’s revenue base. The cash flow that emerges is quasi-infrastructure — which is precisely what lenders and dividend recapitalizations require.
Where It Appears
Conglomerate carve-outs of IT services, logistics, shared-services, and facility units; any deal where the seller remains the dominant customer.
Case File
What Breaks It
The pattern fails when the hostage exchange is asymmetric: if the parent can rebuild the capability in-house cheaper than the contract’s remaining value, the “captive” revenue is a countdown clock, not a moat. Watch the contract renewal terms, not the current revenue split.
Steal This Structure
In any service business, convert your largest client relationship into mutual dependency — embed into their workflow deeply enough that switching costs run both ways — before negotiating long-term terms.
