There is a number negotiated at the closing table, and then there is the number that reaches a seller’s bank account. Deal structures determine the gap between those two figures. Whether a transaction closes as an asset sale or a stock sale is one of the most consequential decisions in any M&A process, yet sellers are almost always less prepared to navigate it than buyers. Understanding the difference, before sitting across from a buyer, is a foundational step in securing the best deal.
Asset Sales
In an asset sale, the business sells its individual components rather than the entity. Asset sales create a complex tax scenario because different assets are taxed at different rates based on their classification. Ordinary income assets, including inventory, accounts receivable, and depreciation recapture, are taxed at rates as high as 37% at the federal level. In contrast, capital assets like goodwill, customer relationships, and certain intangibles receive more favorable long-term capital gains treatment, capped at 20%. If a business operates as a C corporation, sellers could face double taxation in an asset sale. First, the corporation is taxed on the gains from the asset sale. Then, when the proceeds are distributed to shareholders, they are taxed again.
Stock Sales
In a stock sale, the buyer acquires ownership of the business entity itself. Contracts, relationships, and liabilities transfer with the business. The entire gain is typically treated as capital gain, taxed at preferential rates of 0%, 15%, or 20% depending on income level, plus the 3.8% net investment income tax for high earners. The gain on sale is taxed only once at the owner’s individual level. For sellers, this is generally the more favorable structure.
Understanding the Difference
The difference between the two structures can be as much as 17 percentage points on the same headline number. On a $100 million transaction, that spread can represent $10 million or more in tax leakage, before state taxes are applied.
Why Buyers Push for Asset Sales
The structural tension in M&A negotiations is straightforward: what benefits sellers in a stock sale generally costs buyers. In an asset sale, the buyer receives a step-up in basis for the assets acquired, allowing for greater depreciation and amortization deductions going forward. Buyers also avoid inheriting unknown liabilities.
This is why sophisticated acquirers, particularly private equity groups, almost universally favor asset sale structures. Sellers who do not understand the tax math are at a disadvantage before the conversation even starts.
Leverage and Deal Structures
Market dynamics and deal leverage often determine which deal structure is possible. When only one buyer is interested, the buyer influences the terms. Whereas in seller’s markets with multiple interested buyers, sellers may be able to insist on a stock sale structure or demand a price premium to accept an asset sale.
This is the strategic reality that separates a well-managed sale process from a reactive one. When multiple qualified buyers are competing for a business, sellers gain the leverage to shape deal terms, including structure, that protect their take-home number. When a seller is negotiating with a single buyer under time pressure, the buyer dictates the terms.
ArkMalibu’s process is built around creating that competitive environment. Maximizing sale value is not only about the headline purchase price. It is about ensuring every dimension of the deal, from structure to indemnification to working capital adjustments, reflects the seller’s interests rather than the buyer’s preferences.

What Owners Should Know Before Any Deal Conversation Begins
Preparation before a sale starts, not during it, is what separates owners who maximize proceeds from those who leave money on the table. Consider these first steps.
Know the business entity type – Whether the business is structured as a C corporation, S corporation, or LLC determines which deal structures are even available, and what the tax exposure looks like under each one.
Model the after-tax number – A $100 million offer structured as an asset sale and a $100 million offer structured as a stock sale are not the same offer. Working with an advisor to run both scenarios before negotiations begin gives owners a clear picture of what each structure is actually worth in their pocket.
Understand company assets– The composition of a company’s assets directly shapes how the purchase price gets allocated and how much of the proceeds gets taxed at ordinary income rates versus capital gains rates. Knowing this in advance allows sellers to negotiate allocation terms rather than simply accept what a buyer proposes.
The owners who walk away with the most are not always the ones who negotiated the highest headline number. They are the ones who understood what that number became after structure, tax, and terms ran their course.
