Tariffs as a Permanent Planning Assumption: What Business Owners Must Know Before Selling

A year ago, tariffs were a temporary disruption. Today, they are a permanent planning assumption. According to a recent PwC survey, 65% of executives now cite tariff policy as a moderate or severe risk to their business operations, and 69% describe the current regulatory environment as "complex and uncertain." For middle market business owners considering an exit, this shift has profound implications for how your business is valued, how deals are structured, and which buyers will compete for your company.

At Bluefin Capital Advisors, we are seeing tariff-related due diligence questions appear in virtually every transaction we advise on. Buyers are no longer treating tariffs as a one-time cost adjustment — they are modeling them as a structural feature of the operating environment. If you are not prepared to address this in your financials and your narrative, you are leaving value on the table.

How Tariffs Are Reshaping Business Valuations

The KPMG 2026 Business Survey found that 34% of companies are now passing tariff costs directly to customers through price increases. Another 28% have absorbed the costs, accepting margin compression. And 22% have restructured their supply chains to mitigate exposure. Each of these responses tells a different story to a potential buyer — and that story directly affects your multiple.

Buyers evaluating a $5M-$150M revenue business in 2026 are asking three critical questions about tariff exposure. First, what percentage of your cost of goods sold is subject to tariffs, and how has that changed over the past 24 months? Second, have you successfully passed tariff costs through to customers without losing market share? And third, what is your supply chain diversification strategy, and how far along is the implementation?

The businesses commanding premium valuations are those that can demonstrate tariff resilience — either through pricing power that allows cost pass-through, supply chain diversification that reduces exposure, or domestic sourcing strategies that eliminate tariff risk entirely. The businesses trading at discounts are those where tariff exposure is concentrated, unmitigated, and poorly documented.

The Due Diligence Implications

Transaction advisory firm TrVista recently noted that "tariffs and trade dynamics continue to factor into transaction discussions" with buyers focused on understanding the complete supply chain, including countries of origin, alternative sourcing options, and contractual protections. This means your Quality of Earnings analysis needs to clearly separate tariff-related costs from underlying business performance.

A well-prepared seller will have a tariff impact analysis that shows: the gross tariff exposure by product line or supplier, the net impact after price adjustments and supply chain changes, the trend over the past 12-24 months, and the forward-looking mitigation plan. This level of preparation does not just answer buyer questions — it demonstrates the kind of management sophistication that commands premium multiples.

Deal Structure Considerations

The Supreme Court's recent decision on IEEPA tariffs has created a new wrinkle in deal negotiations. As Sidley Austin noted, the ruling has created a pool of uncertain tariff refund claims worth an estimated $150 billion. In M&A transactions, the question of who owns the right to those potential refunds — the seller or the buyer — has become a meaningful negotiation point.

For sellers, the key is to address tariff refund rights explicitly in the purchase agreement rather than leaving them to default allocation rules. If your business has paid significant tariffs over the past several years, those potential refund claims represent real economic value that should be preserved in the transaction structure.

Positioning Your Business for Maximum Value

The business owners who will achieve the best outcomes in this environment are those who treat tariff management as a strategic capability rather than a cost center. That means documenting your tariff mitigation strategies, quantifying the financial impact of your supply chain decisions, and presenting a clear narrative about how your business has adapted to — and thrived in — the current trade environment.

At Bluefin Capital Advisors, we help business owners in the $5M-$150M revenue range navigate these complexities with clarity and confidence. Our advisory process ensures that your tariff story is not a liability in due diligence but a demonstration of management strength that supports premium valuation.
