A Material Adverse Change (MAC) clause, sometimes called a Material Adverse Effect (MAE) clause, is a provision in an acquisition agreement or financing document that allows one party to walk away from a transaction, or to declare a default, if a significant negative change occurs in the target company or borrower’s condition between signing and closing. In the world of M&A and structured finance, few provisions generate as much negotiation, and as much subsequent litigation, as the MAC clause.
In a typical M&A transaction, there is a gap between signing (when the parties agree to the deal and sign the Share Purchase Agreement or Business Transfer Agreement) and closing (when consideration is paid and ownership transfers). This gap may be days, weeks, or months, depending on whether regulatory approvals, shareholder approvals, or other conditions need to be satisfied.
The MAC clause addresses the buyer’s concern: what if the target company deteriorates between signing and closing? Without an MAC clause, the buyer is generally bound to close the transaction at the agreed price regardless of changes in the target’s condition, subject only to breach of representations and warranties. An MAC clause gives the buyer a defined exit right if the deterioration is sufficiently severe.
In lending agreements, MAC clauses serve a parallel function: they allow lenders to refuse to disburse or to accelerate repayment if a material adverse change in the borrower’s financial condition occurs.
Defining “Material Adverse Change”: The Drafting Battle
The MAC definition is where buyer and seller interests diverge most sharply, and where the drafting work is most consequential.
A broad definition (favoured by buyers): “any event, change, effect, or circumstance that has had, or would reasonably be expected to have, a material adverse effect on the business, financial condition, results of operations, assets, liabilities, or prospects of the Company.”
The inclusion of “prospects” is particularly significant, it allows the buyer to claim MAC even without a current financial impact if the future outlook has deteriorated materially.
Carve-outs (favoured by sellers) exclude specified categories of change from the MAC definition, even if those changes are otherwise materially adverse. Standard carve-outs include:
- General economic conditions or market conditions (a recession that affects all businesses is not uniquely the target’s problem)
- Changes in the relevant industry or sector generally
- Changes in financial markets, credit markets, or commodity prices
- Changes in applicable law or regulation, or in GAAP/Ind AS accounting standards
- Acts of God, natural disasters, pandemics, or acts of terrorism
- Changes resulting from the announcement of the transaction itself
- Changes resulting from actions taken or omitted to be taken by the buyer
Post-COVID: The explicit exclusion of “pandemics” and “epidemic” events from MAC definitions has become standard market practice following COVID-19. Sellers now insist on it; buyers negotiate for carve-backs (exceptions to the carve-out) to capture disproportionate effects, i.e., if the pandemic affects the target company materially more severely than comparable companies in the same industry, the disproportionate impact is not excluded.
MAC in Lending Agreements: Event of Default Trigger
In term loan agreements, revolving credit facilities, and bond indentures, an MAC clause typically functions as a representation (which, if untrue, triggers a representation and warranty default) or as a separate event of default.
A lending MAC clause might read: “The occurrence of any event or circumstance that has, or would reasonably be expected to have, a material adverse effect on the financial condition, business, or assets of the Borrower or on the ability of the Borrower to perform its payment obligations under this Agreement.”
Lenders value MAC clauses in loan documents because they provide a contractual basis to accelerate or freeze drawings if the borrower’s condition changes materially, even before an actual payment default occurs.
Interpretation: The High Threshold
Courts, Indian courts applying the Contract Act, and Delaware courts whose decisions are highly influential on Indian M&A practice, have consistently held that MAC clauses are difficult to invoke and require a high evidentiary threshold.
In Akorn Inc v Fresenius Kabi AG (2018), the Delaware Court of Chancery issued the first decision in Delaware’s history upholding a buyer’s right to terminate an acquisition agreement based on an MAC. The Court held that the target had suffered a material adverse effect, but emphasised that the standard requires: (a) a significant decline in financial performance; (b) that is durationally significant (not merely a temporary setback); and (c) that relates specifically to the target, not to general market conditions.
The principles from Delaware cases are regularly cited in Indian M&A negotiations even though Indian courts are not bound by them, because Indian M&A documentation is often modelled on Delaware-style agreements drafted by US or English law firms.
Indian law position: Indian courts apply the Indian Contract Act, 1872. A party seeking to terminate an agreement on MAC grounds must establish that the contractual condition (the MAC) has actually been met, and must comply with any contractual formalities (notice, etc.). Courts will examine whether the MAC clause, on its terms, covers the event in question, and whether any applicable carve-outs apply.
COVID’s Impact on MAC Litigation
COVID-19 produced a significant volume of global MAC litigation, predominantly in the US and Europe, and a smaller volume of Indian disputes. The key outcomes:
- Courts were generally reluctant to permit buyers to rely on MAC clauses solely on the basis of COVID’s general economic effects, because most MAC definitions contained general economic condition carve-outs or pandemic carve-outs.
- Buyers were more successful where they could demonstrate that the target company’s specific condition had deteriorated dramatically and disproportionately relative to its industry peers.
- In India, the COVID period saw several large M&A transactions renegotiated or repriced by agreement rather than litigated, as parties preferred commercial resolution to the uncertainty of MAC litigation.
Key Takeaways
- An MAC clause allows a buyer or lender to exit a transaction or declare a default if a material adverse change occurs in the target or borrower’s condition, but the threshold is high, courts require a significant, durationally meaningful, company-specific deterioration.
- The most commercially important drafting work in an MAC clause concerns the carve-outs: what events are excluded from the definition of MAC, and whether a disproportionate impact exception applies to those exclusions.
- Post-COVID market practice in India now treats explicit pandemic and epidemic carve-outs as standard, with sellers insisting on inclusion and buyers negotiating carve-backs for disproportionate effects.
