Defense Tactics
Compare board-election, asset, and counterbid defenses by control effect, financing need, reversibility, and shareholder cost.
Compare takeover defenses by mechanism, cost, control effect, shareholder impact, and governing evidence.
Takeover defenses are governance, contractual, capital, or transaction measures that can slow an unwanted control attempt, create time to evaluate alternatives, or improve a target board’s negotiating position. They can also impose costs, restrict shareholder choice, change the target’s assets or leverage, and protect incumbent control.
No defense makes a company permanently immune from acquisition. The useful questions are what the measure changes, who can activate or remove it, how long it operates, and whether the board uses the additional time or leverage to improve expected outcomes.
Use Takeover Bids and Defenses when the bidder’s proposal, financing, or control path is the primary issue.
| Area | What changes | Main analytical question |
|---|---|---|
| Board and Asset Defense Tactics | Election timing, asset perimeter, financing, or reciprocal acquisition strategy | Does the response create value-preserving time or damage the target? |
| Poison Pills and Issuer Tenders | Potential ownership dilution or an actual company repurchase | How do trigger terms, funding, dilution, and post-action ownership change? |
| Golden Parachute | Change-of-control compensation and executive incentives | What triggers payment, what does it cost, and how does it affect incentives? |
| Measure | Immediate cash use | Primary effect | Typical evidence |
|---|---|---|---|
| Classified or staggered board | Usually none | Changes director-election and board-control timing | Charter, bylaws, proxy statement, election results |
| Poison pill | Usually limited before trigger | Makes unapproved ownership accumulation potentially dilutive | Rights agreement, board resolution, current report |
| Crown-jewel transaction or option | Depends on structure | Changes access to valuable assets or the transaction perimeter | Asset agreement, option, board disclosure, valuation |
| Pac-Man counterbid | Potentially substantial | Turns the target into a bidder for the original acquirer | Offer documents, financing commitments, regulatory filings |
| Self-tender offer | Substantial if completed | Repurchases shares and changes cash, leverage, and ownership | Schedule TO, offer terms, funding documents, results |
| Golden parachute | Paid only if triggers are met | Changes executive compensation around control and termination | Employment plans, transaction disclosure, compensation table |
The measures can interact. A classified board can make a rights plan harder to remove quickly, while a self-tender can alter the shares outstanding and financing capacity that affect a control contest.
Takeover defenses can affect more than the bidder. Review:
Creating negotiation time is not itself a benefit unless the expected value of the alternatives exceeds the costs and risks introduced.
The SEC transaction and filer reference distinguishes ownership, proxy, merger, going-private, and tender-offer filing families. Rights agreements, compensation arrangements, issuer offers, and material transaction changes can appear across different filings and amendments.
For Delaware corporations, governing documents must be read with current Delaware law. For example, Section 141 of the Delaware General Corporation Law addresses board powers, classified boards, and director removal. Other jurisdictions differ.

Choose a subsection first. Deeper term pages live inside each subsection, which keeps large topic hubs readable.

A golden parachute provides specified executive compensation when a change of control and any required termination conditions occur.
Compare shareholder rights plans and self-tender offers by trigger, dilution, funding, ownership effect, and shareholder choice.
