Buyouts lift supplier sales 8 percent, cut markups in downturns
Suppliers of private equity target firms expand sales by 8 percent and jobs by 4 percent, but see markups drop by 8 percent during downturns. An analysis of Belgian corporate data from 2002 to 2021 shows that buyouts also crowd out rival firms relying on shared suppliers.
More orders, more workers
Private equity acquisitions generate direct spillovers across production networks.
Across the post-buyout period, suppliers linked to acquired firms record approximately 8 percent higher sales and 4 percent higher employment than comparable peers.
These gains stem directly from expanded input purchases rather than technological transfers.
Target firms pursue fresh expansion, prompting embedded suppliers to enlarge capacity to meet rising purchase volumes.
The expansion is concentrated among suppliers that provide a large share of the target's inputs or maintain established ties with the buyer.
Crucially, suppliers show no increase in research and development spending or highly-skilled staffing.
When the cycle turns
During economic downturns, the relationship reverses.
Suppliers of buyout targets see their markups fall by 8 percent as private equity owners enforce cost cuts to service debt obligations.
Furthermore, buyouts ripple outward to competitors sharing the same supply base.
Because expanding targets absorb vendor capacity, suppliers frequently drop rival companies.
A one standard deviation increase in exposure to shared suppliers reduces competitor employment by 1 percent and core earnings by 2 percent.
Debt travels downstream
Buyout risks do not stop at the corporate boundary.
By shifting balance sheet pressure onto suppliers during slumps, private equity turns corporate leverage into supply chain fragility.
Central banks and antitrust authorities can no longer afford to evaluate deals purely through a narrow firm-level lens.
