The Wall Street Journal reported Sunday that the two sides will meet on Sunday to discuss the matter.

The social media giant was expected to reject the offer. The board adopted a measure that would shield it from hostile acquisition bids, a move that is often referred to as a poison pill.

When Musk announced earlier this week that he had lined up financing for the bid, it was reported that he had $21 billion from his personal war chest.

The Journal reported that people familiar with the matter said that the company would speak to the bid on Thursday, when it reports its first quarter earnings.

Musk already has a stake in the social network. The amount of money he lined up is $9 billion more than what he would need to acquire the other 91%.

According to The Journal, Musk emphasized to the shareholders that the board needs to make a decision.
