The Stock Purchase Agreement: An M&A Cornerstone

Introduction: What is a Stock Purchase Agreement (SPA)?

The Stock Purchase Agreement (SPA), often interchangeable with the term Share Purchase Agreement, is a legally binding contract that formalizes the sale and transfer of all or a majority of a company’s outstanding stock from a seller (existing shareholder(s) or the company itself) to a buyer. Unlike an Asset Purchase Agreement, which deals only with specific assets and liabilities, an SPA involves the purchase of the entire entity—the buyer acquires the company lock, stock, and barrel, including all its known and unknown liabilities.

The purpose of a well-drafted SPA is multifaceted: it establishes a clear price, payment structure, and timetable for the transaction, while also serving as the primary tool for allocating risk between the buyer and the seller. Due to the inherent risk of acquiring an entire business, the most heavily negotiated provisions center on post-closing financial protection.

The Anatomy of the Deal: Key Financial and Transactional Clauses

The core of any SPA is the definition of what is being bought and for how much. These sections must be meticulously detailed to prevent post-closing disputes.

1. Purchase Price and Payment Terms

This clause specifies the total consideration for the shares. The purchase price can be a fixed amount or subject to various adjustments.

Provision	Description
Working Capital Adjustment	A mechanism to adjust the final price based on the difference between the target’s net working capital at closing versus a pre-agreed “peg”.
Earn-Outs	Contingent consideration where a portion of the purchase price is paid to the seller only if the company meets specified financial targets (e.g., EBITDA or revenue) post-closing.
Escrow Provisions	A portion of the purchase price is held by a third-party (escrow agent) to secure the seller’s indemnity obligations. This mitigates the buyer’s financial risk.

Risk Allocation: Representations and Warranties (R&Ws)

Representations and Warranties are arguably the most heavily negotiated section, serving as a snapshot of the company’s condition at the time of signing. A Representation is a statement of past or existing fact, while a Warranty is a contractual assurance that if the statement proves untrue, the other party has a remedy.

Protecting the Integrity of the Deal: Covenants and Conditions

2. Covenants

Covenants are promises of future action or non-action by the parties, distinguished into pre-closing and post-closing obligations.

• Pre-Closing Covenants (Interim Operating): These require the seller to operate the business in the “ordinary course” and refrain from certain actions—like incurring new debt or changing employee compensation—without the buyer’s consent during the period between signing the SPA and closing.
• Post-Closing Covenants: These govern the parties’ conduct after the deal is completed, most commonly including non-compete clauses, non-solicitation of employees or customers, and confidentiality obligations.

3. Closing Conditions

The transaction cannot close until all specified conditions are either satisfied or waived. These act as an “out” for a party if fundamental assumptions about the deal change.

The Ultimate Protection: Indemnification Provisions

Indemnification is the clause that converts a breach of an R&W or covenant into a financial remedy. It dictates the terms under which the seller must compensate the buyer for losses incurred due to a breach or a specified pre-closing liability.

Summary of SPA Essentials

A successful acquisition hinges on a precise and well-structured Stock Purchase Agreement. It is a document of disclosure, risk transfer, and operational planning. Here are the three critical components every party must scrutinize:

1. Thorough Due Diligence: The buyer must use the pre-signing period to verify every material statement in the seller’s Representations and Warranties to uncover undisclosed liabilities before closing.
2. Risk Mitigation Mechanisms: Indemnification limits (Caps and Baskets), Escrow, and the scope of R&Ws are vital for defining financial exposure post-transaction.
3. Post-Closing Conduct: Covenants, particularly non-competes and non-solicitation clauses, are essential for preserving the value of the acquired business after the closing date.

Frequently Asked Questions (FAQ)

Q: What is the difference between an SPA and an APA?

A: A Stock Purchase Agreement (SPA) involves the buyer acquiring the shares of the target company, meaning they acquire the entire legal entity along with all its assets and liabilities. An Asset Purchase Agreement (APA) involves the buyer acquiring only specific, listed assets and assuming only specific, agreed-upon liabilities.

Q: Why are Representations and Warranties so important for the buyer?

A: R&Ws are critical because they are the buyer’s primary contractual protection against inheriting unforeseen problems or undisclosed liabilities. If a statement about the company’s condition (e.g., that there is no pending litigation) proves false, the buyer can rely on the R&W for a claim under the indemnification clause.

Q: What is a “basket” in an indemnification provision?

A: A “basket” is a threshold amount that must be reached by the cumulative value of the buyer’s indemnity claims before the seller is required to pay anything. It operates like a deductible in an insurance policy, designed to prevent the seller from facing numerous minor claims post-closing.

Q: What does a “Material Adverse Change” (MAC) clause allow?

A: A MAC clause is a condition to closing that allows the buyer to terminate the acquisition agreement if the target company suffers a significant, detrimental change in its business or financial condition between the date the SPA is signed and the date the deal closes. It protects the buyer from a loss in the fundamental value of the business being acquired.

Q: What is a “Legal Expert” and why do I need one for an SPA?

A: A Legal Expert is a professional who specializes in corporate law and M&A transactions. You need one to draft, negotiate, and scrutinize the highly complex and consequential terms of the SPA, ensuring your rights are protected, risks are properly allocated, and all regulatory and contractual obligations are met.
