Twitter’s Board of Directors announced that it has unanimously approved a plan to protect shareholders’ rights following Elon Musk’s offer to buy the social network.

According to the company, the initiative aims to realize the full value of investors’ investments on Twitter. The plan will run until April 14, 2023.

One defense tactic called the “poison pill” involves protecting a company from unwanted takeovers.

The plan allows shareholders to purchase additional corporate shares at a discount if any entity or individual purchases 15% or more of Twitter without board approval.

Such a decision aims to “blur” the potential buyer’s share to make the takeover less attractive.

Recall, Musk became the company’s largest shareholder after buying a 9.2% stake for $2.89 billion in April. He took the initiative to lower the cost of his Twitter Blue subscription and add payment in Dogecoin (DOGE).

On April 14, Musk offered to buy Twitter for more than $43 billion, explaining this not out of a desire to monetize but to create an “inclusive arena for free speech.”
