Asset Sale or Stock Sale: The Structure Choice That Decides How Much of Your Price You Keep
Two founders I know sold businesses in the same eighteen months at almost exactly the same headline number, a little over eleven million dollars. One of them wired roughly nine million into his personal accounts. The other cleared closer to seven and a half. Same industry, similar margins, no earnout on either deal, no unusual escrow. The entire difference was how the transaction was structured for tax purposes, and the second founder did not learn what that meant until his attorney explained the purchase agreement four weeks after he had already signed the letter of intent. By then the structure was settled. He had traded about a million and a half dollars for a term he had skimmed.
I want to be clear at the front that I am not a tax advisor and nothing here is tax advice for your situation. Structure outcomes turn on your entity type, your basis, your state, how long you have held the stock, and details that only your CPA and your transaction attorney can price. What I can tell you is how this fight actually plays out in lower middle market deals, when it gets decided, and what it costs founders who arrive at it unprepared. That part I have watched many times.
The core tension is simple. Buyers want to buy assets. Sellers want to sell stock. A buyer who purchases assets gets a stepped-up tax basis in what it acquires, which means it can depreciate and amortize those assets going forward and shelter real cash taxes for years afterward. It also gets to choose which liabilities it takes, leaving behind the ones nobody has found yet. A seller who sells stock generally gets one clean layer of capital gains treatment on the whole thing, walks away from most of the historical liability, and does not have to worry about which specific assets carry recapture. Both parties are being entirely rational. They are just rational in opposite directions.
What makes asset treatment expensive for a seller is not usually the headline rate difference. It is the composition. In an asset sale the price gets allocated across categories of assets, and each category is taxed differently. Depreciation you have already taken on equipment comes back as ordinary income through recapture. Inventory and receivables are ordinary. Only the goodwill, which is usually the largest piece, gets capital treatment. So a founder who thought the whole deal would be taxed as a long term gain finds that a meaningful slice is taxed at ordinary rates instead, and if the business is a C corporation, that slice gets taxed once inside the company and again when the money comes out to the owner. The double layer is the part that produces truly ugly numbers, and it is the reason a C corporation asset sale is the outcome most worth working to avoid.
For the roughly two thirds of lower middle market companies that are S corporations, the market has settled on a workaround. The old tool was a Section 338(h)(10) election, which lets the parties treat a legal stock purchase as an asset purchase for tax purposes. It works, but it is brittle. It depends on the target having maintained valid S corporation status without interruption, and S corporation status is very easy to have broken by accident years ago through a sloppy trust ownership or an unintended second class of stock. If that election gets invalidated after the fact, the tax result the buyer paid for evaporates, which is why buyers price that risk into the deal or ask you to indemnify it.
The structure that now dominates is the F reorganization, named for Section 368(a)(1)(F). The mechanics are that you place a new holding company above the operating company, convert the operating company to a disregarded entity, and sell an interest in that entity. The buyer gets asset treatment and a basis step up. The seller keeps favorable treatment on the sale. Contracts and licenses generally stay with the operating entity rather than needing assignment, which matters enormously if you have customer agreements with anti-assignment clauses or licenses that are painful to transfer. And critically, if part of your consideration is rollover equity, the F reorganization is the structure that lets that rollover be tax deferred rather than taxed on day one, which is a difference founders often do not understand until it is too late to fix. I wrote about how that rollover piece works economically in rollover equity is a second deal most founders never negotiate.
Private equity buyers in this market expect the F reorganization and have counsel who run it routinely. It is not an exotic ask. What it is, though, is a preparation problem, because the reorganization has to be done properly and the clean version of it takes time and produces documents that a buyer's counsel will read carefully. Doing it under deal pressure, in the middle of exclusivity, with everyone waiting, is how you get a rushed structure with a defect in it. Founders who look at this in the pre market year and get their entity house in order arrive at the negotiation with the expensive part already solved.
Here is the timing point that costs the most money, and it is the reason I am writing this for founders rather than for advisors. Structure is decided in the letter of intent. Most LOIs contain one or two sentences on the form of transaction, and most founders read past them because they are looking at the number. Once you sign, you are in exclusivity, your leverage falls off, and every structural change you ask for after that is a concession you have to buy back with price. I have described that leverage curve in detail in the no shop clause and why your leverage peaks the day you sign the LOI. Structure belongs on the list of things you settle before that signature, alongside the working capital definition and the escrow.
The right way to hold the conversation is not to demand a structure. It is to price one. If a buyer needs asset treatment and asset treatment costs you an additional eight hundred thousand dollars in tax, then the two structures are not the same deal at the same number, and the difference is negotiable like anything else. Sophisticated buyers understand this. A step up has quantifiable value to them, often worth a real fraction of the purchase price in present value terms, and asking them to share some of what the structure is worth to them is a normal negotiation rather than an insult. What you cannot do is have that conversation without a number, which means you need your CPA to model both structures before the LOI, not after.
A few things I would have modeled early, in the year before going to market. Whether your entity is what you think it is, meaning an actual review of your S election and every ownership change since it was made. What your basis is and how much depreciation recapture is sitting in your fixed assets. Whether any of your value is genuinely personal goodwill rather than enterprise goodwill, which is a real distinction with real consequences and also one that gets asserted aggressively by promoters, so treat it carefully. Whether you have state level exposure that changes the ranking of the options. And whether your stock could qualify for any preferential treatment given your entity history, which is worth confirming rather than assuming in either direction.
The thing to internalize is that structure sits in the same category as the other mechanics that convert a headline number into a wire. The purchase price is the part everyone negotiates hard and the part everyone remembers. The working capital peg, the escrow, the indemnity, the rollover, and the tax structure are the parts that determine what is actually left, and they are collectively worth more movement than the last quarter turn of multiple that founders spend most of their energy fighting for. I laid out that full arithmetic in the equity value bridge, and structure is the line on that bridge that is hardest to see and hardest to reverse.
The Cordis Institute preparation gap study of eighty-nine lower middle market transactions, published at doi.org/10.2139/ssrn.6515478, found that sixty-eight percent of deals saw material adjustments after the letter of intent, with a median compression of nine point eight percent against the LOI number. Tax structure is not usually counted in that compression, because it does not change the price at all. It changes only what you keep, which means it never shows up as a concession and never feels like a loss until the return is filed. That invisibility is precisely why it goes unnegotiated. The same asymmetry drives the pattern I described in why the highest LOI often becomes the lowest close price, where the number that wins the process is rarely the number that reaches the bank.
So the practical instruction is short. Before you sign anything, ask your CPA to run your realistic price through both an asset structure and a stock structure and tell you the after tax difference in dollars. Carry that number into the LOI negotiation and treat the form of transaction as a priced term rather than boilerplate. Which buyer lane you are selling into shapes how much room you have, and the Cordis Institute working paper The Buyer Lane Preparation Map, at doi.org/10.2139/ssrn.6735844, sets out how differently the underwriting models behave on exactly this kind of term. Getting entity structure resolved before a founder goes to market is a standard part of the preparation year we run at Cordis Group, and it is one of the few pieces of that year that can pay for the entire exercise by itself.
