Deal Structures Cheat Sheet

Deal structure determines how an acquisition is legally organized, how the buyer pays, and what tax and liability consequences follow. Getting the structure right is just as important as getting the price right — it affects everyone from shareholders to employees to the IRS.

Stock Deal vs. Asset Deal

FeatureStock DealAsset Deal
What’s AcquiredEntire legal entity (shares)Specific assets and liabilities
LiabilitiesBuyer assumes ALL liabilities (known and unknown)Buyer chooses which liabilities to assume
Tax Basis Step-UpNo — buyer inherits seller’s tax basisYes — buyer gets fair market value basis
Seller Tax TreatmentCapital gains on stock saleOrdinary income on some assets, capital gains on others
Third-Party ConsentsGenerally not required (entity survives)Often required (contracts must be reassigned)
ComplexitySimpler to executeMore complex, requires asset-by-asset transfer
Seller PreferencePreferred (cleaner, capital gains treatment)Less preferred (potential ordinary income)
Buyer PreferenceLess preferred (inherits all liabilities)Preferred (cherry-pick assets, step-up basis)

Forms of Consideration

Merger Structures

StructureHow It WorksWhen Used
Forward MergerTarget merges into buyer, target ceases to existSimple acquisitions, buyer absorbs target
Reverse MergerBuyer merges into target, target survivesPreserving target’s contracts, licenses, public listing
Forward TriangularTarget merges into buyer’s subsidiaryIsolate liabilities from parent, most common in M&A
Reverse TriangularBuyer’s subsidiary merges into target (target survives)Preserve target’s contracts while buyer controls
Tender OfferBuyer offers directly to target’s shareholdersHostile deals or when speed matters, bypasses board

Sources & Uses Table

Every deal model includes a Sources & Uses table that shows where the money comes from and where it goes. This is the financial blueprint of the transaction and feeds directly into the accretion/dilution analysis.

Sources (Where Money Comes From)Uses (Where Money Goes)
Cash on handEquity purchase price
Revolver drawRefinance existing debt
Term loanTransaction fees (advisory, legal)
High-yield bondsFinancing fees
Equity contribution (buyer stock)Cash to balance sheet
Rollover equity (seller reinvestment)Rollover equity (offsets source)
Analyst Tip
In practice, the 338(h)(10) election lets parties treat a stock deal as an asset deal for tax purposes — giving the buyer a step-up in basis while maintaining the simplicity of a stock deal. This is the most common structure in middle-market private company acquisitions.

Key Takeaways

  • Buyers prefer asset deals (cherry-pick assets, step-up basis); sellers prefer stock deals (capital gains, clean exit).
  • All-cash deals provide certainty; all-stock deals enable tax deferral and shared risk.
  • Forward triangular mergers are the most common M&A structure — they isolate liabilities from the parent.
  • Earnouts bridge valuation gaps but create post-closing disputes if metrics aren’t clearly defined.
  • The Sources & Uses table is the foundation of every deal model. See the full M&A process for context.

FAQ

What is the difference between a stock deal and an asset deal?

In a stock deal, the buyer purchases the target’s shares and assumes all liabilities. In an asset deal, the buyer selects specific assets and liabilities to acquire. Stock deals are simpler; asset deals give buyers more control over what they take on.

Why do buyers prefer asset deals?

Asset deals let buyers get a tax basis step-up (higher depreciation deductions going forward), choose which liabilities to assume, and avoid unknown or contingent liabilities that come with buying the entire entity.

What is an earnout in M&A?

An earnout is contingent consideration where additional payments are made post-closing if the acquired business meets certain performance targets (usually revenue or EBITDA milestones). It’s commonly used when buyer and seller disagree on valuation.

What is a reverse triangular merger?

The buyer creates a shell subsidiary that merges into the target. The target survives as a subsidiary of the buyer. This preserves the target’s contracts, licenses, and relationships while giving the buyer control. It’s the most common structure for public company acquisitions.

How does the tax treatment differ between cash and stock deals?

In a cash deal, selling shareholders recognize gain immediately (capital gains or ordinary income depending on structure). In a qualifying stock-for-stock deal, shareholders can defer tax recognition under Section 368 reorganization rules until they sell the acquirer’s stock.
