Business magnate Elon Musk recently concluded his acquisition of Twitter, making him CEO of the communications company.

The process began on April 14 and ended on Oct. 27.

Musk began buying shares in January, becoming the company’s largest shareholder by April. On April 14, Musk offered to purchase the company for $43 billion, at $54.20 per share, and to take the company private. Twitter unanimously accepted the offer to purchase at $44 billion.

On July 8, Musk announced his intention to withdraw, resulting in Twitter launching a lawsuit on July 12. 

On Oct. 3, Musk announced that he had changed his mind, and would continue with the acquisition at the original price of $54.20 per share. On Oct. 13, Reuters reported that Musk was under federal investigation for his conduct. On Oct. 27, Musk announced that he had completed the purchase.

Musk’s purchase of Twitter has caused much controversy, with mixed reactions to the purchase. 

Musk had stated that, in addition to taking the company private, he would introduce new features, combat spambots, and promote free speech. However, there have been fears of a potential increase in misinformation and hate speech on the platform.

Musk had said he planned to cut 75% of Twitter’s workforce, according to an article from the Washington Post on Oct. 20.

Indeed, immediately after his purchase of Twitter was completed on Oct. 27, Musk started to lay off employees, starting with the executives. Musk immediately fired CEO Parag Agrawal and CFO Ned Segal, and dissolved the board of directors, leaving him as the chief executive. 

Musk began laying off a significant portion of the company’s workforce, with the New York Times estimating that at least half of employees had been cut.

True to his word, Musk took the company private, and it was delisted from the New York Stock Exchange (NYSE) on Nov. 8.

In his planned effort to combat spambots, Musk announced that Twitter would require users to purchase Twitter Blue in order to be verified. Musk has not mentioned any other requirements that would be met in order to be verified besides an $8 monthly fee. This policy has caused some concerns over impersonations.

Reception to Musk’s actions has been mixed, with many voicing concern, but in the midst of this Musk himself has tried to sound optimistic.
