Walt Disney Co and Microsoft Corp joined a list of potential suitors for Twitter Inc, according to media reports on Monday.
Twitter shares were marginally down at $23.33 in after-market trading.
The microblogging service has reportedly started talks with a number of technology companies to sell itself, including Google parent Alphabet Inc and may receive a formal bid soon. A source told Reuters that Salesforce.com Inc is also in pursuit.
