Commentary: Could Twitter's 'poison pill' really stop Elon Musk's hostile takeover?

Elon Musk's move to take over Twitter has been temporarily thwarted by the social media company's adoption of a poison pill plan but there are ways to circumvent this, says this finance professor.

BALTIMORE, Maryland: Takeovers are usually friendly affairs. Corporate executives engage in top-secret talks, with one company or a group of investors making a bid for another business. After some negotiating, the companies engaged in the merger or acquisition announce that a deal has been struck.

But other takeovers are more hostile in nature. Not every company wants to be taken over. This is the case with Elon Musk’s US$43 billion bid to buy Twitter.

Companies have various measures in their arsenal to ward off such unwanted advances. One of the most effective anti-takeover measures is the shareholder rights plan, also more aptly known as a “poison pill”. It is designed to block an investor from accumulating a majority stake in a company.

Twitter adopted a poison pill plan on Friday (Apr 15), shortly after Musk unveiled his takeover offer in a Securities and Exchange filing. But why have poison pills been effective at warding off unsolicited offers, at least until now?

HOW DO "POISON PILLS" WORK?

Poison pills were developed in the early 1980s, as a defence tactic against corporate raiders, to effectively poison their takeover efforts sort of reminiscent of the suicide pills that spies supposedly swallow if captured.

There are many variants of poison pills, but they generally increase the number of shares, which then dilutes the bidder’s stake and causes them a significant financial loss.

Let’s say a company has 1,000 shares outstanding valued at US$10 each, which means that the company has a market value of US$10,000. An activist investor purchases 100 shares at the cost of US$1,000 and accumulates a significant 10 per cent stake in the company. 

But if the company has a poison pill that is triggered once any hostile bidder owns 10 per cent of its stock, all other shareholders would suddenly have the opportunity to buy additional shares at a discounted price say, half the market price. This has the effect of quickly diluting the activist investor’s original stake and also, making it worth a lot less than it was before.

Twitter adopted a similar measure. If any shareholder accumulates a 15 per cent stake in the company in a purchase not approved by the board of directors, other shareholders would get the right to buy additional shares at a discount, diluting the 9.2 per cent stake Musk recently purchased.

Poison pills are useful in part because they can be adopted quickly, but they usually have expiration dates. The poison pill adopted by Twitter, for example, expires in one year.

SOME SUCCESS BUT POISON PILLS CAN BE CIRCUMVENTED

Many well-known companies such as Papa John’s, Netflix, JCPenney and Avis Budget Group have used poison pills to successfully fend off hostile takeovers. And nearly 100 companies adopted poison pills in 2020 because they were worried that their careening stock prices, caused by the pandemic market swoon, would make them vulnerable to hostile takeovers.

No one has ever triggered or swallowed a poison pill that was designed to fend off an unsolicited takeover offer, showing how effective such measures are at fending off takeover attempts.

These types of anti-takeover measures are generally frowned upon as a poor corporate governance practice that can hurt a company’s value and performance. They can be seen as impediments to the ability of shareholders and outsiders to monitor management and are more about protecting the board and management than attracting more generous offers from potential buyers.

However, shareholders may benefit from poison pills if they lead to a higher bid for the company, for example. This may be already happening with Twitter as another bidder – a US$103 billion private equity firm – may have surfaced.

A poison pill isn’t foolproof, however. A bidder facing a poison pill could try to argue that the board is not acting in the best interests of shareholders and appeal directly to them through either a tender offer – buying shares directly from other shareholders at a premium in a public bid – or a proxy contest, which involves convincing enough fellow shareholders to join a vote to oust some or all of the existing board.

And judging by his tweets to his 82 million Twitter followers, that seems to be what Musk is doing.
