What is Poison Pill?

Risk: High. Blocks unsolicited acquisitions.

What it is

A poison pill (shareholder rights plan) is a defensive measure that makes a hostile takeover prohibitively expensive, typically by letting existing shareholders buy stock at a steep discount if an acquirer crosses an ownership threshold, diluting the acquirer. It is a board-level anti-takeover device.

Why it matters in your deal

For self-funded buyers, commercial tenants, and franchise candidates, the effect of poison pill depends on the signed wording, related sections, governing law, and transaction facts. The record labels the review priority as: High. Blocks unsolicited acquisitions.

Red flags to watch

  • Watch for a pill with a very low trigger threshold, a long duration with no shareholder vote, or dead-hand features that only the incumbent board can remove.

What to do

  1. 1Locate the operative poison pill wording, its definitions, and its document cross-references.
  2. 2Record the parties, triggers, exceptions, deadlines, and consequences stated for poison pill, then verify any legal conclusion for the governing jurisdiction.
