Non-disparagement Clause
Non-disparagement Clause is a legal and regulatory term relevant to M&A transactions — governing contract rights, regulatory approvals, or post-close obligations.
Full Definition
A non-disparagement clause is a contractual provision that prohibits one or both parties to an agreement from making negative, derogatory, or damaging statements about each other — including statements about the business, its products, services, employees, or management. In M&A transactions, non-disparagement clauses typically appear in purchase agreements, executive employment agreements in connection with acquisitions, and separation agreements when key employees depart post-close. They protect the buyer's reputation and business value from being undermined by the selling party post-transaction.
In business acquisitions, the non-disparagement obligation most commonly runs from seller to buyer. The seller has intimate knowledge of the business's weaknesses, internal problems, and competitive vulnerabilities — information that could be damaging if shared publicly or with customers, competitors, or employees. A non-disparagement clause prevents the seller from using that knowledge to harm the business they've just sold, whether through negative social media posts, competitive intelligence sharing, or disparaging conversations with key customers or employees.
Non-disparagement clauses are closely related to but distinct from non-compete and non-solicitation provisions. Non-disparagement specifically targets negative speech and written communication; non-competes restrict competitive business activity; non-solicitation restricts targeted recruiting of customers or employees. In a complete post-acquisition protection package for an SMB deal, all three provisions typically appear together.
The scope and enforceability of non-disparagement clauses vary by jurisdiction. Most courts will enforce reasonable non-disparagement provisions as written; however, clauses that are so broadly drafted as to prevent truthful statements (especially about matters of public concern) may be challenged on First Amendment or public policy grounds. Well-drafted non-disparagement provisions are narrowly targeted to false and misleading statements rather than all negative speech.
In the context of employee separations post-acquisition, non-disparagement clauses are often mutual — both the company and the departing employee commit not to disparage each other. This mutuality is standard in executive separation agreements and is required in many jurisdictions for the clause to be enforceable. Recent regulatory guidance (from the NLRB and some state agencies) has limited the scope of employee non-disparagement clauses in certain contexts — employment counsel should review these provisions for compliance with current regulations.
Seller vs. Buyer Perspective
Non-disparagement obligations in purchase agreements are standard and reasonable — agree to them as a matter of course for a defined period (2-3 years is typical). What you should negotiate is scope clarity: what constitutes disparagement? Does truthful factual disclosure to a regulatory authority count? Does providing honest references for former employees count? Well-drafted clauses should exclude truthful statements required by law, legal proceedings testimony, and regulatory compliance obligations.
For seller-protective clauses, negotiate mutual non-disparagement — the buyer should not disparage you, your prior management of the business, or your reputation, just as you cannot disparage the business. This is particularly important if you're rolling equity or remaining as a consultant, where the buyer's statements about your prior management could affect your ongoing reputation.
Post-close, be thoughtful about what you say about the acquired business to third parties — even in casual contexts. A negative comment about a customer to a mutual acquaintance, or a critical post about management decisions to a social media audience, could constitute disparagement and create liability.
Non-disparagement provisions protect your acquisition investment from being undermined by the seller's insider knowledge. A seller who tells your key customers that the business "won't be the same under new ownership," or who tells employees that "you'll be sorry the old team is gone," is potentially causing real economic harm — customer attrition and employee turnover — that should be recoverable as a breach of the non-disparagement provision.
Enforce non-disparagement breaches promptly. Courts are more willing to issue injunctive relief to prevent ongoing disparagement than to award damages after customers have already left. If you have evidence of disparaging statements, consult litigation counsel immediately — delay weakens your injunctive relief position.
For deals involving prominent sellers with significant social media presence or industry reputation, the non-disparagement clause is particularly important. A seller with 10,000 LinkedIn followers who posts critical commentary about the acquisition can create significant reputational damage. Consider the seller's communication tendencies when drafting and sizing the clause's scope.
Real-World Example
A buyer acquires a staffing agency. Six months post-close, the former owner (who is no longer involved in the business) posts on LinkedIn: "Sad to see what's happened to the team I built. The new owners clearly don't understand the staffing business, and several key clients have already left. I warned them this would happen." The post generates 200 comments, many from former employees and clients. The buyer's attorney sends a cease-and-desist letter citing the non-disparagement provision in the purchase agreement, demanding a retraction and a corrective post. The former owner complies. The buyer documents the post and asserts a breach of contract claim, recovering $125K in lost client revenue attributable to the post from the indemnification escrow.
Why It Matters & Common Pitfalls
- !Overbroad scope creating unenforceability. Non-disparagement clauses that prohibit all negative speech — including truthful statements, legally required disclosures, and regulatory testimony — may be partially or wholly unenforceable. Narrow the scope to false or misleading statements.
- !No enforcement mechanism. A non-disparagement clause without clear remedies (injunctive relief, liquidated damages) is hard to enforce. Include specific performance remedies and acknowledgment that breach will cause irreparable harm justifying injunctive relief.
- !Social media monitoring neglect. Disparaging statements are made on LinkedIn, Glassdoor, social media, and industry forums — not just in formal communications. Build monitoring into your post-close management if the seller has significant public presence.
- !Failure to address employees. Non-disparagement clauses that bind only the seller (not their controlled entities, employees, or representatives) leave open the possibility that the seller achieves the same harm through agents. Extend the obligation to cover controlled parties and direct reports.
