What Is a Scorched Earth Defence?
A scorched earth defence is an extreme takeover defence in which a target company takes drastic actions to reduce its own attractiveness to an unwanted acquirer. The strategy draws its name from the military tactic of destroying anything useful to an advancing enemy — in M&A, the target destroys or encumbers its own value rather than allow a hostile bidder to capture it.
Scorched earth tactics are among the most controversial defences in M&A because they can harm the target’s own shareholders. They are typically deployed only as a last resort when other defences (poison pills, white knights, litigation) have failed or are unavailable.
Common Scorched Earth Tactics
| Tactic | Description | Effect |
|---|---|---|
| Asset sale | Sell the most valuable division or asset (the “crown jewels”) | Removes the primary reason for the acquisition |
| Debt loading | Take on massive debt through special dividends, leveraged recapitalisations, or acquisitions | Makes the target financially unattractive and difficult to finance |
| Long-term contracts | Enter into onerous long-term supply, licensing, or employment contracts | Creates liabilities that survive the acquisition |
| Golden parachutes | Approve extremely generous change-of-control payments | Increases the cost of the acquisition |
| Poison puts | Issue debt with change-of-control acceleration clauses | Forces immediate repayment of all debt upon acquisition |
| Strategic acquisitions | Acquire a business that creates antitrust issues for the bidder | Regulatory barriers prevent the hostile bid from proceeding |
Legal Constraints
Fiduciary Duties
Directors deploying scorched earth tactics face significant legal risk:
- Business judgment rule — provides protection only if directors act in good faith and on an informed basis
- Revlon duties — once the company is “in play,” directors must maximise shareholder value, not destroy it
- Enhanced scrutiny — courts apply heightened review to defensive actions that impair shareholder value
- Shareholder litigation — scorched earth actions are almost certain to generate lawsuits
Unocal Standard (US)
Under the Unocal test, defensive measures must be:
- Proportionate to the threat posed by the hostile bid
- Not preclusive (must not prevent shareholders from accepting the bid entirely)
- Within the range of reasonable responses
Scorched earth tactics often fail the proportionality test because the cure (destroying value) is worse than the disease (the hostile bid).
Effectiveness and Criticism
Arguments For
- May deter bidders who are only interested in specific assets
- Creates negotiating leverage if the bidder is willing to increase its offer to prevent value destruction
- Signals management’s determination to resist, potentially leading to a higher bid
Arguments Against
- Destroys value for the target’s own shareholders
- May violate fiduciary duties
- Courts increasingly intervene to prevent extreme defensive measures
- Institutional investors and proxy advisory firms oppose scorched earth tactics
According to analysis published by the Harvard Law School Forum on Corporate Governance, scorched earth defences have become rare in practice because courts, shareholders, and governance advisors increasingly view them as disproportionate responses that harm the very shareholders they purport to protect.
APAC Context
Australia — the Corporations Act and Takeovers Panel provide strong constraints on defensive actions. The Panel can declare circumstances “unacceptable” if defensive actions frustrate the bid without a legitimate commercial purpose. Asset sales during a bid period are subject to enhanced scrutiny.
Japan — Japanese courts have historically been more permissive of defensive measures, though the trend is toward greater scrutiny. The 2005 Nippon Broadcasting case and subsequent guidelines established a framework requiring defensive measures to be proportionate and approved by shareholders or independent directors.
India — SEBI’s Takeover Regulations restrict frustrating actions by the target board during a bid period, limiting the ability to deploy scorched earth tactics. Asset disposals, share issuances, and other material actions require shareholder approval once a bid is made.
“Scorched earth defences represent the outer boundary of what boards can do to resist a takeover — and increasingly, the boundary is being drawn tighter by courts and regulators,” notes Daniel Bae, founder of Amafi. “In APAC, where governance norms are evolving rapidly, boards must weigh the legal and reputational risks carefully.”
