    M&A Deal Structure

    Deal structure determines whether an acquirer pays with cash, stock, or a mix, with each option carrying different tax, risk, and dilution implications for both parties.

    Definition

    M&A deal structure refers to the form of consideration and legal framework used to complete an acquisition. The three primary forms of consideration are cash, stock, and a mix of both. Deal structure decisions affect tax treatment for the seller, risk allocation between buyer and seller, accretion/dilution for the buyer, and the overall feasibility of the transaction.

    Risk Allocation by Structure

    Who bears the risk in each deal type

    Cash Deal

    Buyer: HighSeller: Low

    Buyer assumes all integration risk; seller gets certainty

    Stock Deal

    Buyer: MediumSeller: Medium

    Risk shared — both parties exposed to combined entity

    Earnout

    Buyer: LowSeller: High

    Seller bears performance risk post-close

    Cash Deals

    In an all-cash deal, the acquirer pays the target's shareholders entirely in cash. Cash deals are straightforward and provide certainty of value to the seller. They are typically funded through existing cash on hand, new debt issuance, or a combination of both, as outlined in the sources and uses. Cash deals are generally taxable events for the seller's shareholders, who must recognize capital gains immediately.

    Stock Deals

    In an all-stock deal, the acquirer issues new shares to the target's shareholders at a fixed exchange ratio. Stock deals can be structured as tax-free reorganizations, which is a major advantage for sellers. However, stock deals expose the seller to the acquirer's share price risk between announcement and closing. Stock deals dilute existing acquirer shareholders but do not require raising debt or depleting cash reserves. The exchange ratio determines how many acquirer shares each target shareholder receives.

    Mixed Consideration and Election

    Many deals offer a mix of cash and stock to balance the interests of both parties. The mix allocation affects both the tax treatment and the risk profile of the deal. Some transactions offer target shareholders an election to choose between cash and stock, often with proration mechanisms to maintain the desired overall mix. The cash component in a mixed deal is generally taxable while the stock portion may qualify for tax deferral.

    Tax and Strategic Considerations

    From the seller's perspective, stock deals are preferred when shareholders want to defer capital gains taxes and maintain exposure to the combined entity. From the buyer's perspective, the choice depends on relative share price valuation, available cash and debt capacity, and the impact on credit metrics. If the acquirer believes its stock is overvalued, a stock deal effectively lets it buy the target at a discount. If the acquirer believes its stock is undervalued, a cash deal avoids giving away cheap shares.

    Worked Example — With Real Numbers

    An acquirer with 100M shares outstanding at $50/share ($5B market cap) wants to acquire a target for $2B. In an all-cash deal, it might raise $2B in new debt. In an all-stock deal, it issues 40M new shares (at $50 each) to the target's shareholders, bringing total shares to 140M. In a 50/50 mixed deal, it pays $1B cash and issues 20M shares. The cash deal adds leverage but avoids dilution; the stock deal avoids leverage but dilutes EPS by 40/140 = 28.6%.

    Key Takeaways

    1

    Cash deals provide value certainty to sellers but are typically taxable and require financing

    2

    Stock deals can be tax-free for sellers but expose them to acquirer share price risk

    3

    Mixed deals balance cash certainty with tax efficiency and dilution management

    4

    Acquirers prefer stock when they believe their shares are overvalued and cash when undervalued

    5

    Deal structure directly affects accretion/dilution analysis and post-deal capital structure

    Common Mistakes in Interviews

    Assuming all M&A deals are cash deals — many large transactions use stock or mixed consideration

    Forgetting the tax implications for sellers when comparing cash vs. stock consideration

    Ignoring the signal that deal structure sends — paying with stock may suggest the acquirer thinks its shares are overvalued

    How Interviewers Test This

    If asked why an acquirer would choose stock over cash, discuss three factors: (1) preserving cash and debt capacity, (2) sharing risk with the target's shareholders, and (3) potential tax-free treatment for the seller. Then note the drawback: dilution to existing shareholders and signaling that management may view its stock as fully valued.
