Startup M&A: What Founders Need to Know Before Signing an Acquisition Term Sheet

For many startup founders, an acquisition offer represents the culmination of years of work. But the letter of intent (LOI) or term sheet is the beginning of a complex legal process — not the end. Understanding the key deal terms before signing protects founders from surprises that can significantly erode the economics of a deal that looks attractive on the headline number.

Asset Deal vs. Stock Deal

The first structural question in any acquisition is whether it will be structured as an asset purchase or a stock (or merger) transaction.

Asset Purchase:

• Buyer purchases specific assets and assumes specified liabilities
• Seller entity survives and retains unassumed liabilities
• Favorable for buyers (cherry-pick assets, avoid hidden liabilities)
• Step-up in asset basis for the buyer
• Often less favorable for sellers due to double taxation (corporate + individual level)

Stock Purchase or Merger:

• Buyer acquires the entire legal entity and all its liabilities
• More straightforward for sellers — single level of capital gains treatment
• Preferred by startup founders and investors because of tax efficiency and QSBS eligibility
• Requires buyer to conduct thorough due diligence on all liabilities

Most venture-backed startup acquisitions are structured as stock purchases or mergers for these reasons.

Key LOI / Term Sheet Provisions

Purchase Price and Consideration

• Is consideration all cash, all stock, or a mix?
• If acquirer stock: is it public (liquid) or private (illiquid)?
• What is the escrow or holdback amount and period?

Representations and Warranties

The definitive agreement will require the company and its stockholders to make extensive representations and warranties — factual statements about the business that, if false, give the buyer legal remedies.

Common reps and warranties cover:

• Corporate organization and authority
• Capitalization (accuracy of the cap table)
• Financial statements
• IP ownership and absence of infringement
• Material contracts
• Litigation and regulatory matters
• Employee and labor matters
• Tax compliance

Indemnification: If a rep and warranty is breached post-closing, stockholders may be required to indemnify the buyer for losses. Key negotiating points include:

• Cap: Maximum indemnification liability (often 10–20% of deal value, or the escrow amount)
• Basket/Deductible: Minimum threshold before indemnification obligations trigger
• Survival period: How long after closing reps survive (typically 12–24 months for general reps; longer for fundamental reps and tax matters)

Representations and Warranties Insurance (RWI)

In larger deals, buyers increasingly obtain R&W insurance — a policy that pays claims for rep breaches directly from the insurer, rather than from escrow or seller indemnification. This allows sellers to receive cleaner exits with faster release of escrowed funds.

Earnouts

An earnout is a contingent payment tied to post-closing performance metrics — revenue targets, EBITDA milestones, product launch dates. Earnouts are common when buyer and seller disagree on valuation.

Earnout risks for founders:

• The acquirer controls the business post-closing and may make decisions that adversely affect earnout achievement
• Accounting disputes over how earnout metrics are measured
• Integration decisions (headcount reductions, product pivots) that make milestone achievement impossible

Founders should negotiate earnout protective provisions including: obligations on the acquirer to operate the acquired business in a manner consistent with achieving milestones, anti-sandbagging provisions, and clear accounting definitions.

Treatment of Options and Warrants at Closing

Acquisitions trigger significant decisions about unvested options:

• Accelerated vesting: Single-trigger (upon change of control) or double-trigger (upon change of control and subsequent termination)
• Rollover options: Unvested options may roll over into acquirer equity
• Cash-out: Options may be cashed out at the spread value

These terms significantly affect key employee retention and founder economics.

Exclusivity and No-Shop

LOIs almost always include an exclusivity period (typically 30–60 days) during which the company agrees not to solicit or engage with other potential acquirers. Before granting exclusivity, founders should:

• Conduct a market check (engage other potential buyers) to establish competitive tension
• Ensure the exclusivity period is short enough to create urgency on the buyer
• Preserve the right to respond to unsolicited approaches

Due Diligence: What to Expect

Acquirers will conduct extensive due diligence covering legal, financial, technical, and commercial matters. Common deal-killers discovered in diligence include:

• Missing or incomplete IP assignments from founders or early employees
• Open-source code incorporated in proprietary products without license compliance
• Cap table discrepancies or undocumented equity grants
• Regulatory non-compliance (data privacy, industry-specific licensing)
• Undisclosed litigation or regulatory investigations

Preparing a clean data room before signing an LOI accelerates diligence and reduces deal risk.
