STOCK AND MEMBER INTEREST PURCHASE AGREEMENTS
Understanding Stock and Membership Interest Purchase Agreements
A Stock or Membership Interest Purchase Agreement is a legal contract used to transfer ownership in a business through the sale of stock (in a corporation) or membership/partnership interests (in an LLC or partnership). Unlike asset purchase agreements, which allow buyers to selectively acquire specific assets and liabilities, stock and interest purchases transfer full ownership of the business entity itself. This includes the company’s legal structure, assets, liabilities, contracts, and obligations. These agreements are common in closely held or service-based businesses, where operational continuity is crucial. However, because the buyer inherits all liabilities—known and unknown—rigorous legal and financial due diligence is critical to mitigate risk. While these transactions can be simpler on the surface, they carry substantial consequences without proper planning and drafting.
Key Differences Between Stock and Asset Purchases
Stock or interest purchases transfer control of the business entity as a whole, maintaining all existing operations, contracts, and relationships. Asset purchases, on the other hand, involve cherry-picking which assets and liabilities the buyer wants to assume. Asset deals often require more granular documentation and may involve third-party consents for specific asset transfers. Read our blog, "Asset Purchase Agreements: Securing Your Business Acquisition," for more information. In contrast, equity-based transactions streamline administrative steps but require comprehensive representations, warranties, and indemnification provisions to allocate and manage liability. These structural differences impact everything from deal complexity to tax treatment, making it essential to choose the right structure based on the business, its goals, and its risks.
Core Components of a Purchase Agreement
A well-drafted stock or membership interest purchase agreement begins by identifying the parties, stating the purpose of the transaction, and defining key legal and financial terms—many of which are subject to negotiation. The agreement then sets out the purchase price, payment method (e.g., cash, notes, stock, or earn-outs), and payment schedule, all of which carry tax implications and should be reviewed with financial advisors. It also describes the ownership interest being transferred, including the number and type of shares or units, voting rights, and any transfer restrictions.
The seller typically provides extensive representations and warranties about the company’s compliance, finances, operations, legal status, and intellectual property. These disclosures give the buyer a foundation for post-closing remedies. The buyer, in turn, confirms their legal authority and financial ability to complete the purchase. The agreement also includes covenants—promises to act or refrain from acting—both before and after closing. These may include continuing operations in the ordinary course, non-compete and non-solicitation clauses, or obligations to cooperate on tax filings and customer transitions. Conditions to closing, such as securing financing or obtaining third-party approvals, must be clearly stated, as must any termination rights and related fees. Indemnification provisions govern how breaches or losses will be handled and set limitations on liability. Lastly, standard legal terms—such as governing law, dispute resolution, and cost allocation—round out the agreement.

Handling Exits and Ownership Transfers in Closely Held Businesses
When a member or shareholder leaves a company, their interest is typically transferred through a membership or stock interest purchase agreement. These agreements are often shorter than full acquisition contracts but still must comply with securities laws and the company’s governing documents. The agreement identifies the parties, details the interest being transferred, and ensures the buyer agrees to abide by the company’s operating or shareholder agreement.
Before finalizing the transfer, parties must address any personal guarantees or fiduciary obligations of the departing owner, assess whether the transfer triggers change-of-control provisions, and confirm valuation terms—ideally defined in the operating agreement. The final document should also include terms for price, liability transfers, and any post-exit restrictions such as non-compete or confidentiality clauses. For administrative continuity, companies must update ownership records with the Secretary of State, revise IRS filings, adjust bank authorizations, and update internal documents to reflect the new ownership structure.
