NEW YORK ( TheStreet) -- Vodafone ( VOD) shares were higher by 3.8% to $30.72 in premarket trading Thursday after a Reuters report said Verizon ( VZ) hired advisers in advance of a potential $100 billion cash and stock bid to acquire the 45% of Verizon Wireless it doesn't already own. Reuters noted a bid has not been made as of yet, but recent talk from both Verizon and Vodafone has stoked investors' appetites on a deal being done as soon as possible. On Verizon's most recent earnings call, Chief Financial Officer Fran Shammo said he thought a deal could be done in a tax-efficient matter, which has been one of the sticking points of a potential deal. Equinix ( AAPL) shares tumbled 3.44% in premarket trading to $208.94 after the data center company reported first-quarter earnings that missed estimates and guided revenue below expectations.

Equinix said second-quarter revenue would be between $530 million and $534 million. Analysts polled by Thomson Reuters are expecting $541.7 million in sales.
