Greenmail or greenmailing is the practice of purchasing enough shares in a firm to threaten a takeover, thereby forcing the target firm to buy those shares back at a premium in order to suspend the takeover.
The term is a neologism derived from blackmail and greenback as commentators and journalists saw the practice of said corporate raiders as attempts by well-financed individuals to blackmail a company into handing over money by using the threat of a takeover.
Corporate raids aim to generate large amounts of money by hostile takeovers of large, often undervalued or inefficient (i.e. non-profit-maximizing) companies, by either asset stripping and/or replacing management and employees. However, once having secured a large share of a target company, instead of completing the hostile takeover, the greenmailer offers to end the threat to the victim company by selling his share back to it, but at a substantial premium to the fair market stock price.
From the viewpoint of the target, the ransom payment may be referred to as a goodbye kiss. The origin of the term as a business metaphor is unclear. A company which agrees to buy back the bidder's stockholding in the target avoids being taken over. In return, the bidder agrees to abandon the takeover attempt and may sign a confidential agreement with the greenmailee, guaranteeing not to resume the maneuver for a period of time.
While benefiting the predator, the company and its shareholders lose money. Greenmail also perpetuates the company's existing management and employees, which would have most certainly seen their ranks reduced or eliminated had the hostile takeover successfully gone through.
Greenmail proved lucrative for investors such as T. Boone Pickens and Sir James Goldsmith during the 1980s. In the latter example, Goldsmith made $90 million from the Goodyear Tire and Rubber Company in the 1980s in this manner. Occidental Petroleum paid greenmail to David Murdock in 1984.
The St. Regis Paper Company provides an example of greenmail. When an investor group led by Sir James Goldsmith acquired 8.6% stake in St. Regis and expressed interest in taking over the paper concern, the company agreed to repurchase the shares at a premium. Goldsmith's group acquired the shares for an average price of $35.50 per share, a total of $109 million. It sold its stake at $52 per share, netting a profit of $51 million. Shortly after the payoff in March 1984, St. Regis became the target of publisher Rupert Murdoch. St Regis turned to Champion International and agreed to a $1.84 billion takeover. Murdoch tendered his 5.6% stake in St. Regis to the Champion offer for a profit. (Source: J. Fred Weston, Mark L.Mitchell J.

Changes in the details of corporate ownership structure, in the investment markets generally, and the legal requirement in some jurisdictions for companies to impose limits for launching formal bids, or obligations to seek shareholder approval for the buyback of its own shares, and in Federal tax treatment of greenmail gains (a 50% excise tax) have all made greenmail far less common since the early 1990s (see 26 U.S.C. § 5881, and 26 C.F.R. Part 156, notably § 156.5881-1 ff.).
