Private equity firms are operating in one of the toughest deal environments in recent memory. Higher interest rates and tighter valuations mean that every assumption in the model is under scrutiny. Financial, legal, and tax diligence are always central, but operational diligence, especially supply chain performance, too often gets overlooked.

This blind spot is costly. Supply chains are no longer just a cost center. They are a lever for growth, resiliency, and long-term value creation. When ignored, they become the unseen drag that sinks returns.

It is tempting to assume that if EBITDA is strong, the supply chain must be stable. Yet financials can mask fragility:

• Outdated freight contracts that lock in inflated costs.
• Hidden accessorial charges that quietly erode margins.
• Fragile provider networks that collapse under stress.
• Weak compliance practices that invite regulatory penalties.

One PE firm acquired a consumer products company that appeared to be on solid footing. Six months later, customs non-compliance and inflated freight rates caused shipping delays and added millions in unexpected costs. EBITDA projections collapsed by 20 percent. The financials looked fine, but the supply chain was the iceberg lurking beneath the surface.

To prevent these failures, PE firms should:

• Make supply chain health a core diligence workstream. Put it on par with financial and legal reviews.
• Look beyond cost. Evaluate resiliency, scalability, and ability to support growth.
• Stress-test for disruption. Model tariff changes, inflation spikes, and port delays.
• Leverage external expertise. Benchmarks and third-party insights uncover risks insiders normalize.

For private equity firms, supply chains can make or break returns. Treating them as a priority in diligence will protect valuations and strengthen long-term deal outcomes.
