What Is a Definitive Agreement? A Founder's Guide to M&A and Fundraising
The definitive agreement is the final, legally binding contract in your M&A or financing deal. This guide breaks down what you need to scrutinize before you sign.
TL;DR: A definitive agreement (DA) is the final, binding contract for a business transaction like an M&A deal, superseding any prior term sheet or LOI. It details all terms, conditions, representations, and obligations. Founders must scrutinize clauses like indemnification, reps and warranties, and purchase price adjustments, as they carry significant post-closing risk and liability.
Key takeaways
- The Definitive Agreement is legally binding and supersedes all prior agreements, including the term sheet.
- Scrutinize the Reps & Warranties and disclose all exceptions in the Disclosure Schedules.
- Negotiate the indemnification cap, basket, and escrow terms to limit your post-closing liability.
- Understand the mechanics of purchase price adjustments like working capital targets and earn-outs.
- Distinguish between an Asset Purchase (selling specific assets) and a Share Purchase (selling the company).
- Your legal counsel is critical. Do not attempt to negotiate the DA without experienced M&A lawyers.
From Handshake to Hard Reality: The Definitive Agreement
The definitive agreement (DA) is the final boss of any major business transaction. Whether you're selling your company, raising a large strategic round, or entering a joint venture, this is the document that turns months of negotiation into legally binding reality. Unlike a term sheet or Letter of Intent (LOI), which are expressions of intent, the DA is the instrument of transfer. When you sign it, you have a done deal.
It supersedes every conversation, email, and prior agreement. What you thought you agreed to on a call doesn't matter. Only what is written in the DA matters. For this reason, you and your legal counsel must treat it with extreme gravity. A single overlooked clause can have multi-million dollar consequences years after the ink is dry.
This isn't a time to save on legal fees. You need an experienced M&A lawyer who has seen dozens of these deals. The other side will have one. Your cousin who does real estate law is not the right person for this job.
Share Purchase vs. Asset Purchase: What Are You Actually Selling?
A deal can be structured in two primary ways. The distinction is critical, as it determines what the buyer gets and what liabilities you (the seller) are left with.
Share Purchase Agreement (SPA)
This is the most common structure for selling a venture-backed startup. The buyer acquires the actual shares of your company, becoming the new owner of the legal entity.
- What they buy: Everything. The buyer purchases the entire company as a going concern—all assets, contracts, intellectual property, bank accounts, and, crucially, all liabilities, known and unknown.
- Implication for you: The legal entity you built continues to exist, just under new ownership. The buyer inherits your tax history, any pending legal issues, and any skeletons in the closet. Because of this, the buyer will demand extensive promises from you about the state of the company.
Asset Purchase Agreement (APA)
In an asset purchase, the buyer does not buy your company but instead buys specific, itemized assets from it. This is more like going to a store and picking items off a shelf.
