NEW YORK (TheStreet) -- Shares of Verizon Communications (VZ - Get Report) were lower in pre-market trading on Friday as the company sought to reduce its $4.8 billion takeover offer for digital information company Yahoo (YHOO) by $1 billion, sources say, the New York Post reported.

This follows Yahoo's disclosure last month of a widespread data hack of about 500 million user accounts in 2014.

Additionally, reports earlier this week alleged that Yahoo searched users' incoming emails last year following orders from the Justice Department.

Verizon, a New York-based telecom company, believes Yahoo has not been forthcoming in deal talks and that its value has been diminished following the reports, sources said.

But Yahoo is pushing for the acquisition and is arguing against changing the terms, sources told the Post.

Verizon is also considering setting aside a reserve of $1 billion for potential legal issues surrounding the Yahoo hack, sources added.

The company's strengths can be seen in multiple areas, such as its solid stock price performance, expanding profit margins and notable return on equity. We feel its strengths outweigh the fact that the company has had sub par growth in net income.
