What Is a Stock Purchase Agreement?

A stock purchase agreement is a contract in which a buyer acquires shares of stock in a corporation from one or more selling shareholders. Rather than purchasing the corporation’s assets directly, the buyer acquires the stock itself – and with it, ownership of the entire corporation including all of its assets, contracts, liabilities, and obligations. Stock purchase agreements are the equity-purchase equivalent for corporations of what a membership interest purchase agreement is for LLCs.

What Does a Stock Purchase Agreement Cover?

  • Shares being transferred – the number and class of shares being sold and the resulting ownership structure after closing
  • Purchase price and payment terms – total consideration, any adjustments, and payment structure including escrow, seller financing, or earnout provisions
  • Representations and warranties of the seller – the seller’s statements about the corporation, its capitalization, financial condition, liabilities, contracts, litigation, and operations
  • Representations and warranties of the buyer – the buyer’s statements about its authority and financial capacity to close
  • Covenants – obligations of the parties between signing and closing, including how the business will be operated in the interim
  • Conditions to closing – what must occur before the transaction closes, including regulatory approvals if required
  • Indemnification – the seller’s obligation to compensate the buyer for losses arising from breaches of representations or undisclosed pre-closing liabilities
  • Non-compete and non-solicitation provisions – post-closing restrictions on selling shareholders who were involved in the business

Stock Purchase vs. Asset Purchase

Buyers and sellers often have different preferences when it comes to deal structure. In general, buyers tend to prefer asset purchases because they can limit liability exposure by selecting which assets and liabilities to acquire. Sellers may prefer stock purchases for different reasons. The right structure for any particular transaction depends on the specific circumstances of the deal, and both buyers and sellers should consult with their own legal and tax advisors before agreeing to a structure.


Frequently Asked Questions – Stock Purchase Agreements in New York and New Jersey

Does buying stock in a corporation mean I inherit all its liabilities?

Yes. When you buy stock in a corporation, you acquire the entire legal entity – including all of its existing liabilities, whether known or unknown at the time of purchase. This is why thorough due diligence is critical in stock purchase transactions, and why buyers negotiate robust indemnification provisions to protect against undisclosed pre-closing liabilities. Escrow arrangements are also common, allowing the buyer to withhold a portion of the purchase price to cover potential indemnification claims.

What other documents are typically signed alongside a stock purchase agreement?

A stock purchase agreement is the primary contract, but the closing typically involves additional documents. These commonly include a closing certificate from each party confirming their representations remain accurate, stock certificates or other instruments evidencing the transfer of shares, and any required consents or approvals. If the selling shareholders are remaining involved in the business post-closing, the package may also include employment agreements, consulting agreements, or non-compete agreements. If there is seller financing, a promissory note and related security documents may also be part of the closing package.

What due diligence should a buyer conduct before purchasing stock in a corporation?

Because a stock purchase results in the buyer acquiring the entire corporation – including all of its liabilities – thorough due diligence is essential. A review typically covers the corporation’s financial statements, tax returns, contracts, outstanding or threatened litigation, employment matters, intellectual property, real estate, regulatory compliance, and corporate records including the cap table. Russo Law LLC guides buyers through the due diligence process in connection with business acquisitions throughout New York and New Jersey.
