Definitive Agreement

A definitive agreement is the binding contract that consummates an acquisition, typically negotiated over 6 to 12 weeks after the LOI is signed. It is also called a definitive purchase agreement, DPA, merger agreement, or stock purchase agreement depending on deal structure. It covers the final negotiated purchase price, the transaction structure, representations and warranties, indemnification provisions, escrow holdbacks, closing conditions, and post-close covenants. It is the document that turns the LOI's non-binding intentions into legally enforceable terms, and the negotiation phase where the headline price quietly moves by 10 to 30 percent in either direction depending on what due diligence reveals.

The major sections of a typical definitive agreement: purchase price and structure (final cash and stock components, formula for any adjustments at close such as working capital true-up, treatment of debt, allocation across share classes), representations and warranties (statements by seller about the state of the business (financial accuracy, no undisclosed liabilities, IP ownership, customer contracts, employee matters), breach of which triggers indemnification), covenants (what each party will and won't do between signing and closing, and post-close), closing conditions (regulatory approvals like HSR antitrust, third-party consents, financing if applicable, no material adverse change), indemnification (caps and floors on seller liability for rep breaches, typically capped at 10 to 30 percent of deal value with survival periods of 12 to 24 months), escrow holdback (a portion of proceeds held in escrow to satisfy indemnification claims), and termination provisions (what happens if the deal breaks before close, including break-up fees for either side). Two structures matter most: stock purchase agreement (buyer acquires the target's shares; tax-efficient for sellers in many cases; buyer inherits all liabilities) versus asset purchase agreement (buyer acquires specified assets and liabilities; cleaner for buyer; tax-disadvantaged for sellers in most cases). The signing-to-close window varies: simple deals close in 30 to 60 days, deals with regulatory clearance can take 6 to 12+ months, deals with major customer-consent requirements can take 90 to 180 days.

What founders get wrong: Negotiating the LOI hard and then assuming the definitive will follow suit. Buyers commonly hold tough on definitive terms (wider indemnification, longer survival periods, larger escrows, sandbagging waivers) more than the LOI implied, knowing that during exclusivity the seller has limited leverage to walk away. Plan for the re-trade and have your lawyer flag every term that moved between LOI and definitive.

The binding contract that consummates an acquisition, including the final negotiated purchase price, structure, representations and warranties, indemnification, escrow holdbacks, closing conditions, and post-close covenants. Typically negotiated over 6 to 12 weeks after the LOI is signed.

Stock purchase: the buyer acquires the target's shares; tax-efficient for sellers in many cases; buyer inherits all liabilities. Asset purchase: the buyer acquires specified assets and liabilities; cleaner for the buyer; tax-disadvantaged for sellers in most cases. The choice has major tax and risk implications for both sides.

How long does definitive agreement negotiation take?
Typically 6 to 12 weeks from LOI signing to definitive execution, depending on deal complexity and how much got pre-negotiated in the LOI. Signing-to-closing can add another 30 to 60 days for simple deals, 90 to 180 days with major customer-consent requirements, or 6 to 12+ months with regulatory clearance.
