Exit Strategy & M&A: Planning How You'll Eventually Sell

Exit planning feels premature for most founders — something to think about "someday," once a real acquisition offer is actually on the table. But many of the decisions that most directly shape how much you actually keep from an eventual sale get made years earlier, quietly, often without anyone realizing they're exit decisions at all: which entity structure you chose, how clean your cap table and contracts are, whether your financial records would survive real scrutiny, and — for a C-corp — whether your stock even qualifies for the single most valuable exit tax benefit available to a startup founder.

Why this matters so much: several of these decisions genuinely cannot be retrofitted. A tax clock that needs to start running years before a sale can't be backdated once the sale conversation starts. This module isn't about planning an exit you're not ready for — it's about understanding which foundational choices quietly determine your options later, so you can make them deliberately now.

In a stock sale, the buyer purchases the company's shares directly — the company itself, with all its assets and liabilities, changes hands as a single unit. In an asset sale, the buyer purchases specific assets (equipment, contracts, IP, customer lists) rather than the legal entity itself.

Why sellers usually prefer stock sales: the seller typically recognizes a single layer of capital gain, often at a lower effective rate. Why buyers usually prefer asset sales: the buyer gets a "step-up" in tax basis on the acquired assets, which increases future depreciation and amortization deductions — a real, ongoing tax benefit — and the buyer can more selectively avoid inheriting unknown or undisclosed liabilities.

This tension is often a genuinely large amount of money, not a rounding error. On a $10 million sale, a C-corporation seller might net roughly $6 million after tax in an asset deal versus roughly $7.6 million in a stock deal — a real, seven-figure gap on a deal that size, driven by the C-corp double-taxation effect (the corporation pays tax on the asset sale gain, and the shareholder pays tax again on the distributed proceeds). That gap is exactly what tends to drive hard-fought negotiation over deal structure, and often gets partially bridged through price adjustments or other deal terms.

The Letter of Intent (LOI) is typically a non-binding document outlining the proposed deal's key terms — price, structure, timeline — before the parties invest in full due diligence. It sets the roadmap, even though most of its terms aren't legally enforceable.

Due diligence is the buyer's deep investigation of your business — financials, contracts, legal history, IP ownership, employee agreements — to confirm what they're actually buying matches what they were told. This is exactly why the "getting exit-ready" work below matters: a business whose records don't hold up under real scrutiny can see a deal fall apart, or the price cut, during this phase.

Earnouts are a way to bridge a valuation gap when the buyer and seller disagree about what the business is worth — part of the purchase price is deferred and paid later, contingent on the business hitting specific performance targets post-close. Earnouts can make an otherwise-stuck negotiation possible, but they carry real risk: disputes over how the earnout is measured and managed after the buyer takes control are one of the most common sources of post-acquisition conflict, so the specific metrics and calculation method need to be defined with real precision, not left vague.

A business sale is very likely one of the highest-stakes, most complex transactions a founder will ever be part of — and it's exactly the kind of transaction where DIY-ing the negotiation and paperwork to save money is a false economy. An experienced M&A attorney catches deal-structure and liability issues a founder won't think to look for; an investment banker or M&A advisor can run a genuine competitive process instead of negotiating against a single buyer alone (which materially affects price); and a CPA familiar with M&A ensures the deal structure and QSBS eligibility are actually preserved through the transaction, not accidentally forfeited by a technical misstep. The fees for this team are a small fraction of what a single bad term in a once-in-a-lifetime transaction can cost.
