Greenmail is a colorful term for a practice that's essentially a form of corporate blackmail. It happens when an investor or a group buys a large number of a company's shares on the open market and then threatens a hostile takeover or a proxy fight. To fend off the unwanted suitor, the target company's management agrees to buy back the shares from the aggressor at a significant premium—a price well above the current market value. The would-be raider pockets a handsome profit and walks away, leaving the other shareholders to foot the bill. The term itself is a clever play on “blackmail” and “greenback” (a slang term for the U.S. dollar), highlighting the financial nature of the threat. While it was a hallmark of the go-go 1980s, it's now widely seen as a predatory tactic that enriches a single activist investor at the expense of the company and its long-term shareholders.
Imagine a corporate drama unfolding in three acts. The process is surprisingly straightforward, though the implications are complex.
The 1980s were the golden age of greenmail, and one of the most famous examples involved The Walt Disney Company. In 1984, financier Saul Steinberg acquired a 6.3% stake in Disney and threatened a hostile takeover and proxy fight to break the company up. Disney’s management, led by Ron W. Miller, was terrified of losing control of the beloved entertainment empire. The solution? They paid Steinberg a massive greenmail payment. Disney bought back his shares for $325.5 million, handing Steinberg a cool profit of about $60 million for just a few months of “work.” To finance the payment, Disney had to take on significant debt, which weakened its financial position. The episode was a public relations disaster and ultimately contributed to Miller being replaced by a new management team later that year. This story, along with the exploits of other famous raiders like Carl Icahn and T. Boone Pickens, cemented greenmail's notorious reputation.
Technically, greenmail isn't illegal. It's a private transaction between a company and one of its shareholders. However, its controversial nature has led to measures designed to curb it. In the United States, for instance, the Internal Revenue Service (IRS) imposes a hefty 50% excise tax on greenmail profits, making the practice far less attractive than it once was. Furthermore, many companies have adopted their own defenses.
For the average shareholder, greenmail is almost always bad news. Here’s why:
From a value investing standpoint, greenmail is the antithesis of a sound investment strategy. Value investors, following the philosophy of Benjamin Graham and Warren Buffett, seek to be long-term partners in a business. They buy shares in wonderful companies at fair prices and hold them, allowing the company's intrinsic value to grow over time. Greenmail is a short-term, opportunistic tactic that often damages a company's long-term prospects by draining its resources. A true value investor would look at a company paying greenmail and see a red flag: a management team willing to destroy shareholder value to save their own skin. While the raider's argument is sometimes that they are shaking up a complacent and inefficient management team, the greenmail payoff is a resolution that benefits only the raider, not the business itself or its committed owners.
