Chapter 1. The Art of Contracts: Poison Pill Exploration and Defense

Just as battlefields have shields and walls, the M&A market—a battlefield of capital—has Poison Pills. These sophisticated booby traps, set to protect corporate control, sometimes protect shareholder interests and at other times are misused for the job security of management.


1. What is a Poison Pill?

A poison pill refers to any measure that makes it “difficult for an acquirer to swallow the company,” such as granting existing shareholders the right to issue new shares at a low price or making it difficult for a hostile acquirer to take over the company’s books.

(1) Why Install It?

  • Defense against Hostile M&A: Makes it difficult for an attacker to exercise actual management control even after securing a stake.
  • Strengthening Bargaining Power: Induces the acquirer to pay a higher price (premium).
  • Protecting Shareholder Value: Protects long-term corporate value from short-term speculative forces.

4. Conclusion: Poison Can Be Medicine

A poison pill is a double-edged sword. It can make a company sustainable by protecting capable management, but it can also become a means of ‘Entrenchment’ that allows incompetent management to cling to their positions.

Tip

Prof. Sean’s Insight: “True poison pills are not just in the contract.” The ability to read the fine print hidden behind the Articles of Incorporation is the mark of a sophisticated strategist.
