Definition

What is a material adverse effect?

A material adverse effect (MAE) is a defined term that sets how bad a negative change must be before it lets a buyer walk away from a deal, lets lenders refuse to fund, or makes a representation untrue. A typical material adverse effect definition reads: “Material Adverse Effect means any event, change or effect that has had or would reasonably be expected to have a material adverse effect on the business, results of operations or financial condition of the Company and its Subsidiaries, taken as a whole…” — followed by a list of carve-outs.

A material adverse change (a MAC clause) and a material adverse effect clause mean the same thing in practice — some agreements call it a material adverse clause or a material adverse event. What matters is the definition itself and where the term is used — as a closing condition, a representation or, in a credit agreement, a condition to borrowing or an event of default.

An MAE is one of several deal-risk clauses to check in buy-side due diligence, alongside change of control clauses in the target's contracts. Continua's risk and red-flag analysis traces them across the whole data room.

MAE in credit agreements: lender definitions usually have few or no carve-outs and add the borrower's ability to perform, the validity of the loan documents and the lenders' rights and remedies — see how Continua supports commercial credit review.

Examples

Material adverse effect clause examples

Illustrative drafting — and how the checker reads each one.

Forward-looking

“Would reasonably be expected to”

…any Effect that, individually or in the aggregate, has had or would reasonably be expected to have a material adverse effect on the business, results of operations or financial condition of the Company…

Flagged as forward-looking and aggregated — effects that haven't happened yet can count.

Carve-out

Disproportionate effect

…except, in the case of clauses (i) through (v), to the extent such Effect has a disproportionate adverse effect on the Company relative to other participants in its industry.

Each listed carve-out is marked “excluded unless disproportionate”.

Lender MAE

Credit agreement

…a material adverse effect upon the legality, validity, binding effect or enforceability of any Loan Document or the rights and remedies of the Lenders thereunder.

Flagged as covering the lenders' rights and remedies — typical lender drafting.

Broad

Includes prospects

…a material adverse change in the business, assets, operations, condition (financial or otherwise) or prospects of the Borrower and its Subsidiaries, taken as a whole.

Flagged: “prospects” makes the standard broader and harder to measure.

FAQ

Frequently asked questions

What does “material adverse effect” mean?

A defined term that sets how bad a negative change must be before a party can refuse to close, call a default or treat a representation as breached.

Is a MAC clause the same as an MAE clause?

In practice, yes. “Material adverse change” and “material adverse effect” are used interchangeably; what matters is the definition and where it is used.

What are typical MAE carve-outs?

General economic, market and industry conditions, changes in law or accounting, war, pandemics, announcement of the deal, missed projections and stock price changes.

What is a disproportionate-effect exception?

A proviso that lets an excluded event, such as an industry downturn, count again to the extent the company is hit harder than its peers.

How often do courts find a material adverse event?

Rarely. Akorn v. Fresenius (Del. Ch. 2018) is the best-known Delaware case in which a buyer was allowed to terminate because of an MAE.

How is an MAE different in a credit agreement?

Lender definitions usually have few or no carve-outs and also cover the borrower's ability to pay and the lenders' rights and remedies.
