The Global Risks Alliance (GRA)
Many private-equity holdings are manufacturers, distributors and industrial service firms that depend on a small number of suppliers, components, sites or customers. Concentration lowers cost in normal times and transmits disruption in abnormal ones. This page sets out how supply and industrial exposure develops in sponsor-backed companies, how it propagates through production networks and across a portfolio, how it is mapped when supplier data are incomplete, and what the evidence serves for the boards and owners who decide.

Supply chain concentration is dependence on a small number of suppliers, components, sites or customers. Many private-equity holdings are manufacturers and distributors where concentration lowers cost in normal times and transmits disruption when a supplier fails, a trade measure lands or a conduct problem surfaces deep in the chain.
Where a portfolio's assets sit, and how much of its value is most exposed. Hypothetical assets, not an assessment.
Concentrated suppliers and manufacturing. The dossier below sets out how the risk develops, what is measured, where the data come from, how it is modelled and who decides.
Procurement savings often come from consolidating suppliers. Where a component has one qualified supplier, its failure stops production until a replacement is qualified, which for engineered or regulated products can take many months.
Companies usually know their direct suppliers but not their suppliers' suppliers. Concentration in a sub-tier, such as a chemical, a semiconductor or a casting, can affect many apparently diversified suppliers at once.
Tariffs, export controls, sanctions and shipping disruption change cost and availability across whole product categories. Companies with thin margins and fixed-price contracts absorb the shock in earnings.
Several companies in one fund may rely on the same region, input or logistics provider. Disruption at that node reaches several holdings together, concentrating loss in a way company-level review does not show.
Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.
| Term | Definition |
|---|---|
| Sole source | A component available from only one supplier, as distinct from single sourcing by choice. |
| Supplier tier | A supplier's position in the chain: tier one supplies the firm, tier two supplies tier one, and so on. |
| Inventory cover | How long stocks of a critical input would last at current use. |
Each indicator carries its unit, its cadence, the kind of source behind it and the evidence label a value would carry. No values are shown: a programme supplies them under its own authority.
| Indicator | Unit | Cadence | Source type | Label |
|---|---|---|---|---|
| Supplier concentration | share of spend with the largest suppliers | annual | Procurement records | REPORTED |
| Sole-source components | count and share of bill of materials | annual | Engineering and procurement records | REPORTED |
| Supplier mapping depth | tiers mapped, by spend category | annual | Supplier surveys and mapping | DECLARED |
| Inventory cover for critical inputs | days of production | monthly | Inventory records | REPORTED |
| Supplier lead-time variability | days, dispersion around the mean | monthly | Purchase order records | OBSERVED |
| Revenue exposed to trade measures | share of revenue, by trade route and product code | per policy change | Trade classification of products | ESTIMATED |
| Substantiated supply-chain conduct findings | count, by category | annual | Audits and grievance mechanisms | REPORTED |
The topic as a computational graph: named sources feed the methods, an evidence review gates the outputs, and the decisions stay with the authorities that hold them.

Private Equity Nexus prepares evidence. The decisions below are taken by the authorities named, under their own rules, and never by the platform.
| Who decides | The question | Evidence this page serves |
|---|---|---|
| Portfolio-company boards | Whether to dual-source, hold strategic inventory or redesign products around constrained inputs | Sole-source counts, inventory cover and disruption pathways |
| General partners and operating teams | Whether shared exposures across holdings justify portfolio-level procurement or contingency work | Portfolio overlap of regions, inputs and logistics providers |
| Lenders | Whether supply concentration is reflected in projections and covenant headroom | Disruption scenarios with stated assumptions |
| Limited partners and their stewardship teams | Whether managers carry out risk-based supply-chain due diligence as the OECD Guidelines expect | Due-diligence practice evidence and conduct findings, labelled by source |
Supply chains optimized for cost tend to converge on the same low-cost suppliers and locations. The resulting concentration is invisible in normal times and becomes visible only when a shock removes a link that many companies shared.
Specialized inputs may have one qualified supplier, so its disruption stops production.
Suppliers clustered in one region share exposure to the same hazards and policies.
Companies that look diversified may depend on the same deep-tier suppliers.
Tracing suppliers tier by tier. Limits: deep tiers are opaque and change over time.
Measuring dependence on suppliers and regions. Limits: describes exposure, not probability of disruption.
Testing operational and financial effects of supplier loss, using scenario design and stress testing. Limits: illustrative.
Assessing exposure to trade measures, using financial economics and macro-finance. Limits: policy changes quickly.
The current service level is R0: information and enquiries. An enquiry receives a reference and names the next step; applications, payments, compute allocations and registrations open only when their team, terms and review capacity exist.
