What Are the Key Steps in a Corporate Sale?

Each phase involves distinct documentation, approval requirements, and timing pressures. Early disclosure and clear contractual boundaries reduce the seller's exposure to indemnification claims. Thorough due diligence and detailed representations in the purchase agreement establish the buyer's foundation for post-closing remedies if hidden liabilities emerge.

Due diligence is the buyer's systematic investigation of the target company's financial, legal, and operational condition. The seller's obligation to disclose material facts and respond to information requests shapes the buyer's ability to identify risks and pursue breach-of-warranty claims if the seller withheld or misrepresented information.

The buyer's legal team typically reviews financial statements, tax returns, customer and supplier contracts, employment records, litigation history, compliance files, and intellectual property registrations. The seller provides documents through a data room, a secure online repository where materials are organized and access is controlled. Any material omission or inaccuracy in the seller's responses can expose the seller to indemnification liability after closing. Courts examine whether the seller's disclosures were complete and whether the buyer had a reasonable opportunity to discover omitted facts.

The buyer's due diligence window is typically 30 to 90 days. If the buyer fails to ask the right questions during that window, the buyer may lose the ability to renegotiate price or terminate before closing. Conversely, if the seller knowingly withholds information or makes false statements, the buyer may pursue post-closing indemnification or rescission claims, though such remedies depend on the purchase agreement's survival period and the buyer's ability to prove reliance.

The purchase agreement is the binding contract that governs the sale. It specifies the purchase price, adjustment mechanisms such as working capital or earn-out provisions, representations and warranties each party makes, indemnification obligations, and conditions that must be satisfied before closing. The agreement's language directly affects each party's post-closing remedies and exposure.

Representations are factual statements about the target company's condition, such as the financial statements are accurate and there are no undisclosed liabilities. Warranties are promises that those representations are true and will remain true, subject to the agreement's survival period. If a representation proves false after closing, the buyer can pursue indemnification against the seller, subject to baskets, caps, and time limits specified in the agreement.

A typical purchase agreement includes a representation and warranty survival period, often 12 to 24 months after closing, during which the buyer can bring indemnification claims. Some reps, such as those regarding title, taxes, and environmental compliance, may survive longer or indefinitely. The agreement typically includes a basket (a threshold below which the buyer cannot claim indemnification) and a cap (a maximum amount of indemnification liability). These thresholds protect the seller from nuisance claims but also limit the buyer's recovery for smaller breaches.

Earn-out provisions add complexity. In an earn-out, part of the purchase price is contingent on the target company's future performance. This structure aligns the seller's interest in the business's continued success, but it creates post-closing disputes about calculation, whether the buyer has fulfilled its obligations to support the business, and whether the buyer has manipulated expenses or revenue to reduce the earn-out payment. Courts have held that the buyer owes the seller a duty of good faith and fair dealing in administering earn-outs, but proving a breach requires detailed financial analysis and expert testimony.

Depending on the target company's industry and size, the sale may require regulatory approvals from antitrust agencies, securities regulators, banking authorities, or industry-specific bodies. A material adverse change clause (MAC clause) in the purchase agreement allows either party to terminate the deal if an unforeseen event materially harms the target company's value or operations.

In practice, MAC clauses are rarely invoked successfully because courts interpret them narrowly, requiring proof of a truly extraordinary event that was not foreseeable at signing. A general economic downturn or industry-wide decline is typically not enough to trigger a MAC. The burden of proof is on the party asserting the MAC, and that party must demonstrate that the event has had a material and durable impact on the business.

In a corporate sale involving significant market share or competitive overlap, the transaction may trigger antitrust review under the Hart-Scott-Rodino Act if certain size thresholds are met. The buyer and seller must file a notification with the Federal Trade Commission and the Department of Justice and wait for clearance before closing. The waiting period is typically 30 days but can be extended if the agencies issue a second request for information. The purchase agreement typically allocates the risk of antitrust delay or challenge between the buyer and seller, specifying who bears the cost of remedies and whether either party has the right to terminate if clearance is not obtained by a specified date.

After closing, the buyer's primary remedy for breach of representations or warranties is indemnification. The buyer must provide the seller with written notice of the claim, typically within the survival period, and must prove the breach and the amount of damages. Common post-closing disputes include undisclosed liabilities, inaccurate financial statements, customer concentration, and breach of non-compete covenants.

The indemnification process can stretch over months or years, especially if the buyer and seller disagree about damages or whether a particular liability was actually unknown at closing. Many purchase agreements include a dispute resolution mechanism, such as expedited arbitration or expert determination, to resolve disagreements faster than litigation.

The statute of limitations for breach of contract in New York is generally six years, but the purchase agreement's survival period is often shorter. Once the survival period expires, the buyer loses the right to bring indemnification claims for that category of representation, even if the breach is discovered later. This creates a timing trap for the buyer. If the buyer does not discover a breach until after the survival period has passed, the buyer's only recourse may be a separate claim for fraud or negligent misrepresentation, which carry different burdens of proof and shorter statutes of limitations.

For sellers, the goal is to minimize post-closing indemnification exposure by ensuring that all material facts are disclosed during due diligence, that representations are carefully drafted to reflect the seller's actual knowledge, and that survival periods and caps are negotiated to reasonable limits. Sellers should also consider escrow arrangements, where a portion of the purchase price is held by a third party and released only after a specified period or after disputes are resolved.

For buyers, the goal is to conduct thorough due diligence, negotiate detailed and specific representations that cover all material aspects of the business, obtain representations regarding the seller's knowledge and investigation, and negotiate for longer survival periods on critical reps such as those regarding litigation and environmental compliance. Buyers should also reserve the right to audit the seller's compliance with earn-out calculations.

Both parties benefit from clear contractual language that addresses ambiguities in advance, such as how working capital will be calculated, what constitutes a material adverse change, and how disputes will be resolved. Vague or conflicting language often leads to post-closing litigation that costs both parties far more than a negotiated compromise would have.

In the context of aircraft sales transactions or other specialized asset classes, the same core principles apply, though industry-specific regulations and valuation methods may add complexity. Similarly, issues that fall under the broader umbrella of business, corporate, and securities law may govern the treatment of securities, regulatory filings, and disclosure obligations in the sale.

The key to a successful corporate sale is preparation. Before initiating the sale process, sellers should audit their own records, remediate compliance gaps, and assemble a comprehensive data room. Buyers should engage legal and financial advisors early and develop a detailed due diligence checklist tailored to the target company's industry. Both parties should treat the purchase agreement as a living document that clearly allocates risk in a way that reflects each party's bargaining power and risk tolerance. By investing time and resources upfront in disclosure, documentation, and careful drafting, parties can significantly reduce the likelihood of post-closing disputes and the cost of resolution if disputes do arise.
