Key events in Elon Musk’s takeover of Twitter

It comes after months of public sparring between both sides and even the threat of a court case to force through the deal when the billionaire threatened to pull out.

But now the Tesla and SpaceX boss is in control of the social media platform.

Here is a timeline of how the deal unfolded:

– April 4: A filing to the US Securities and Exchange Commission (SEC) shows Mr Musk bought up just over 9% of Twitter shares, at the time making him the firm’s largest shareholder.

– April 5: Twitter announces Mr Musk would be joining the company’s board.

– April 11: Mr Musk reverses his decision and Twitter confirms the billionaire will not be joining the board.

– April 14: Mr Musk submits an offer to buy the company outright and take it private. He offers 44 billion US dollars (£36.5 billion) – or 54.20 US dollars (£45) per share.

– April 15: In response, Twitter plans to implement what is known as a “poison pill” policy, which would allow existing shareholders to buy stock at discounted rates to dilute Mr Musk’s holdings and prevent the sale. But Mr Musk and Twitter enter into negotiations over a deal.

– April 25: A deal is agreed on the price Mr Musk initially offered – 44 billion US dollars.

– May 10: During a public appearance, Mr Musk says he would reverse Twitter’s current permanent ban on the account of former US president Donald Trump.

– May 14: Mr Musk begins to raise questions over the number of bot accounts on the platform and says the deal is “temporarily on hold” while he tries to find out more about the levels of spam and fake accounts on Twitter.

– May 16: Mr Musk continues to spar publicly with Twitter executives, sending a poo emoji in response to a tweet from Twitter chief executive Parag Agrawal which reiterates the firm’s belief that only 5% of accounts on the site are bots.

Mr Musk also uses a public appearance later that day to suggest a deal for the platform could be done at a lower price and estimates that Twitter is, at best, 20% bots.

– May 17: Mr Musk says the deal “cannot move forward” until he gets “proof” that bots are only 5% of spam accounts on the platform. A number of experts suggest he is trying to force the renegotiation of the deal at a lower price.

On the same day, Twitter says it still planned to “close the transaction and enforce the merger agreement” with Mr Musk.

– June 6: Mr Musk says he has a “right to terminate the merger agreement” in a letter from his lawyers to Twitter’s legal team over what he claims is the company’s lack of co-operation over the spam accounts data.

– June 8: Twitter agrees to give Mr Musk access to its data “firehose” which contains the data around all public tweets to help with his investigation.

– July 7: The Washington Post reports that Mr Musk’s deal to buy Twitter is “in peril” after his team concluded Twitter’s figures on spam accounts are not verifiable.

– July 8: The deal collapses after Mr Musk sends a letter to the SEC saying he is terminating the acquisition.

In the letter, he says Twitter has “not complied with its contractual obligations” surrounding the deal, namely giving him enough information to “make an independent assessment of the prevalence of fake or spam accounts on Twitter’s platform”.

In response, the chair of Twitter’s board, Bret Taylor, said it is “committed” to closing the transaction on the price and terms agreed upon with Mr Musk and plans to pursue legal action to enforce the merger agreement.

– July 12: Twitter launches legal action. Mr Musk later countersues, accusing the company of misleading his team about the true size of its user base and other problems he said amounted to fraud and breach of contract.

– July 19: Judges in the US state of Delaware set a date in October for the trial.

– August 5: Court documents show that Twitter accused Mr Musk of “looking for an excuse” to get out of the deal because the stock market decline meant it was no longer favourable for him.

– August 6: Mr Musk publicly comments on how he can move forward with the deal in response to a Twitter user who posts a series of tweets about the bid.

He says: “Good summary of the problem. If Twitter simply provides their method of sampling 100 accounts and how they’re confirmed to be real, the deal should proceed on original terms. However, if it turns out that their SEC filings are materially false, then it should not.”

– August 23: A former company executive at Twitter turned whistleblower, Peiter “Mudge” Zatko, says the microblogging website has substantial security problems that place personal user data and potentially national security at risk.

In response, Twitter disputes Mr Zatko’s account, describing it as a “false narrative about Twitter and our privacy and data security practices that is riddled with inconsistencies and inaccuracies”.

– October 4: Twitter said it plans to close a deal to sell the company to Mr Musk after receiving an offer.

– October 6: A judge delays the looming trial between Twitter and Mr Musk in order to give the billionaire time to complete the acquisition.

– October 26: Mr Musk posts a video of himself entering Twitter’s head office in San Francisco, just days before the court deadline to complete the deal.

He also changes his Twitter bio to refer to himself as Chief Twit and updates his location to Twitter headquarters in a sign the deal looks set to be closed.

– October 27: Sources confirm Mr Musk has taken over Twitter and dismissed three of its top executives.
