How to Choose the Right M&A Deal Structure
The headline price in an LOI is a head fake. Your real payout depends on the deal structure—stock sale vs. asset sale—and obscure terms like escrow and working capital adjustments. Here's how to win the negotiation.
TL;DR: The sticker price of an acquisition offer is misleading. The structure of the deal—typically a stock sale, asset sale, or merger—has a far greater impact on your net cash outcome due to taxes, liability, and risk. To maximize your take-home pay, you must aggressively negotiate terms like escrow, earnouts, and working capital, and avoid common founder mistakes like going cheap on M&A-specific legal counsel.
Key takeaways
- Always push for a stock sale; it offers the cleanest exit and best tax treatment for you.
- Treat earnouts as worth $0. You lose control of the variables needed to achieve them.
- Define "working capital" with extreme precision in the LOI to avoid last-minute price reductions.
- A large part of your "price" is often a retention package. Negotiate it like a separate employment agreement.
- Hire a specialist M&A lawyer and tax advisor. Your general counsel is not equipped for this.
- Model every offer's net outcome in a spreadsheet. A higher price can easily net you less cash.
'''The Most Important Number Isn't the Price
You have an offer to be acquired. The number in the Letter of Intent (LOI) makes your heart race. But the headline price is a head fake. It’s a number designed to get you emotionally committed before the real negotiation begins.
An offer for $50M can easily put less cash in your pocket than a $40M offer with a better structure. The real equation for your take-home pay looks more like this:
(Purchase Price - Escrow - Working Capital Adjustments + Value of Rollover Equity) * (1 - Your Effective Tax Rate) - Legal Fees + Your New Retention Package = Your Actual Outcome
First-time founders fixate on the purchase price. Seasoned operators know the game is won or lost in the structure. Your buyer understands this better than you do. Let’s fix that.
The Primary Battleground: Stock Sale vs. Asset Sale
Nearly all acquisitions boil down to one of two core structures: a stock sale or an asset sale. A third type, a merger, is often a hybrid that functions like a stock sale for tax purposes. Your interests and the buyer’s are diametrically opposed, and this is where the first, most important negotiation happens.
1. The Stock Sale: Your Default Goal
The buyer purchases all of your company's outstanding shares directly from your stockholders—you, your employees, and your investors. The corporate entity you built continues to exist, just with a new owner.
- How it works: Simple and clean. The buyer acquires your entire company "as is"—assets, liabilities, contracts, the works.
- Why you want it: It’s the gold standard for sellers. Your proceeds from selling the stock are treated as long-term capital gains (assuming you’ve held for >1 year). This is the lowest, most favorable tax rate you can get. From a liability perspective, you hand over the keys to the entire corporate entity, and its history becomes the buyer's problem.
- Why the buyer resists: They inherit everything—including "unknown" liabilities. A potential lawsuit, a tax audit from two years ago, an environmental issue—it's all theirs now. They also don't get a "stepped-up basis" for the assets, a jargon-heavy way of saying they can't re-depreciate your assets to lower their future tax bills.
