IPA: /ˈɡriːnˌmeɪlər/
KK: /ˈɡrinˌmeɪlər/
A person who uses threats of a hostile takeover to force a company to buy back their shares at a premium price.
The greenmailer pressured the company into buying back its shares to avoid a takeover.
Greenmailer is formed from "green" (from Old English "grene", meaning the color of growing plants) and "mailer" (from Old French "mail", meaning a person who sends). The term refers to someone who uses the threat of a hostile takeover to extort money from a company, often implying a connection to environmental or green issues.
Think of 'green' as relating to growth and nature, and 'mailer' as someone who sends something. This helps you remember that a greenmailer is someone who sends threats related to financial extortion, often with a focus on environmental concerns.
