The M&A Term Sheet: What It Is, Why It Matters, and What to Watch For

You operate a startup and a potential acquirer has reached out. First off, congratulations! Now, after weeks of introductory calls, management presentations, and high-level diligence, the other side is ready to put something on paper. That something is a term sheet (sometimes called a letter of intent, or LOI).

For many founders, the term sheet represents the first time a deal feels real. It is also, in our experience, the document that is most frequently misunderstood. Founders sometimes treat it as a mere formality; a handshake in writing before “the lawyers get involved.” Others treat every word as if it carries the same legal weight as the final purchase agreement. Neither framing is quite right.

In this post, we break down what an M&A term sheet actually is, why it matters more than you might think, and walk through the core provisions you will find in nearly every deal.

What Is a Term Sheet?

An M&A term sheet is typically a non-binding (with limited exceptions) document that outlines the principal economic and structural terms of a proposed acquisition. Think of it as the blueprint, not the building. It is the agreed-upon summary of the deal before teams of lawyers and other advisors spend months drafting, negotiating, and closing the definitive transaction documents.

Term sheets come in different forms. In a strategic acquisition of a venture-backed startup, you will often see a multi-page letter of intent. In a private equity context, you may see a more detailed term sheet. The format matters less than the substance, and the substance matters more than founders often realize.

Why the Term Sheet Matters

We often hear from founders who want to skip careful review of the term sheet and “get to the real documents.” We strongly advise against this approach, for three reasons:

1. It sets the proverbial anchor. Once a number or structure is agreed upon in a term sheet, it is psychologically (and sometimes practically) very difficult to move it in the definitive agreements. The final deal almost always reflects the term sheet, even if that was never your intention.

2. Exclusivity is binding and costly. The moment you sign a term sheet with a no-shop clause, you are legally prohibited from soliciting or entertaining other offers for a defined period — often 30 to 60 days, sometimes longer. That is real leverage you are handing to the buyer, and you should understand exactly what you are agreeing to.

3. Structural choices have massive economic consequences. Whether the deal is structured as a stock purchase, asset purchase, or merger; whether there is an earnout or escrow; how reps and warranties are scoped — these decisions, often captured in a single line in the term sheet, can translate to millions of dollars of difference at close.

Key Terms Found in Almost Every M&A Term Sheet

Below we walk through the key provisions you should expect to see, and the questions you should be asking about each one.

1. Purchase Price and Consideration

This is the headline number, but the headline rarely tells the full story. The purchase price section will specify:

• The total enterprise value or equity value being offered.
• The form of consideration (whether that be cash, acquirer stock, or a combination of both).
• Whether any portion of the purchase price is deferred, contingent, or subject to a holdback.

If the consideration includes acquirer stock, pay close attention to valuation, lock-up periods, and registration rights. Illiquid stock is not the same as cash, and in a downturn it can be worth substantially less than the headline number suggests.

2. Earnout Provisions

An earnout is a mechanism by which a portion of the purchase price is paid post-closing based on the acquired company achieving specified financial or operational milestones. They are common when a buyer and seller disagree on valuation, often because the seller believes future performance will justify a higher price.

Earnouts sound attractive in the abstract. In practice, they are frequently a source of post-closing disputes. Before agreeing to a meaningful earnout, founders should think carefully about: who will control the business post-close (and therefore control whether milestones are hit), how the metrics are defined and measured, and what happens in the event of a future sale of the acquirer.

3. Deal Structure: Stock vs. Asset Purchase vs. Merger

The structure of a transaction has significant tax, liability, and operational implications for both sides:

• Stock purchase: The buyer acquires the company’s equity directly. Sellers generally prefer this because gains are taxed at capital gains rates. Buyers often prefer it less because they inherit all known and unknown liabilities.
• Asset purchase: The buyer selects which assets (and liabilities) to acquire. Buyers often prefer this for the liability protection it provides, and because it often comes with a step-up in the tax basis of the assets being purchased. The tax treatment is more complex and can be less favorable for sellers.
• Merger: The target company merges into the buyer (or a subsidiary of the buyer). The mechanics vary by state and deal complexity, but mergers are common for larger public-company acquisitions, and less so for private startup acquisition.

4. Representations, Warranties, and Indemnification

The term sheet will typically include a high-level description of the representations and warranties that the company and its sellers will be required to make in the definitive agreement. These are factual statements about the business — e.g., that financial statements are accurate, there is no undisclosed litigation, intellectual property is owned free and clear, and so on.

Equally important is the indemnification framework — meaning, what happens if a rep turns out to be untrue after closing. Key variables include:

• Survival period: How long after closing can a buyer bring a claim?
• Basket / deductible: A minimum threshold before indemnification kicks in.
• Cap: The maximum amount sellers can be required to pay for indemnification claims.

Representation and Warranty (R&W) insurance has become increasingly common in middle-market and larger deals. It shifts the indemnification risk from the sellers to an insurance policy, which can be a significant benefit for founders looking for a cleaner exit.

5. Escrow and Holdback

Buyers frequently require that a portion of the purchase price be set aside for a period (often as long as 12 to 18 months) after closing. Often times, this will be as much as 10-15% of the purchase price. When the buyer retains the funds itself, this is called a holdback. When a disinterested third-party agent is brought in to custody the funds, this is called escrow. A holdback or escrow serves as security for indemnification claims. Only after the survival period expires, and assuming no claims have been made, does the held amount get released to sellers.

Founders should negotiate both the size of the holdback/escrow and the duration carefully. A large escrow for a long period is effectively a deferred payment that carries real risk, particularly if the buyer turns out to be litigious or if the business is in a complex industry with regulatory exposure.

6. Treatment of Equity: Options, Warrants, and Convertible Notes

If your company has issued stock options, warrants, or convertible instruments, the term sheet should address how they will be treated at closing. Common approaches include:

• Accelerated vesting: Single-trigger (upon a change of control) or double-trigger (upon a change of control plus termination) acceleration provisions in your option plan will dictate whether unvested options accelerate.
• Cash-out vs. rollover: Will in-the-money options be cashed out at closing, or will option holders be required to roll into equity of the acquiring entity?
• Conversion of convertibles: Outstanding SAFEs, convertible notes, and warrants will convert or be cashed out per their terms. Review those terms now to understand the waterfall.

7. Conditions to Closing

The term sheet will typically identify the conditions that must be satisfied before closing can occur. These commonly include: completion of satisfactory due diligence, receipt of any required regulatory approvals, third-party consents (such as key customer or landlord consents), and execution of definitive agreements.

Pay attention to how broadly these conditions are written. A buyer with broad, discretionary conditions has significant leverage to walk away from the deal (or renegotiate terms) even after you are locked up under exclusivity.

8. Exclusivity (No-Shop)

As noted below, this is one of the only truly binding provisions in most term sheets. The exclusivity clause prohibits you from soliciting, encouraging, or negotiating with other potential acquirers for a defined period. Once signed, you are committed.

Negotiate the length carefully. Thirty days is reasonable for a motivated, well-organized buyer. Sixty days or more is a meaningful concession.

9. Employee Matters and Retention

Many acquirers will expect key employees (founders included) to remain with the business post-closing for some period. The term sheet may address:

• Founder employment or consulting agreements post-close.
• Employee retention pools: A pool of equity or cash set aside to retain key non-founder employees through and after the transition.
• Non-competition and non-solicitation obligations on founders and other key personnel.

These provisions can significantly affect your actual economic outcome. A two-year employment requirement with a clawback in the event of voluntary departure is very different from a clean, immediate payout.

Final Thoughts

An M&A term sheet is not just a formality — it is the foundation upon which the entire deal will be built. The economic outcomes for you and your team, the protections (or lack thereof) you will have post-closing, and the risk profile of the transaction are all shaped, often irreversibly, by what you agree to at this stage.
