NEW YORK (TheStreet) -- The final bid to purchase Yahoo's (YHOO) core business is due today as the one-time Silicon Valley giant prepares for a takeover, CNBC's Scott Wapner reported on "Fast Money Halftime Report" Monday.

Bidders are expected to be Dan Gilbert, founder of Quicken Loans, Verizon (VZ), TPG, Advent International, Vista Equity Partners, and AT&T (T).

The company expects to receive some bids today, but will not make a decision on who wins anytime soon, Yahoo former interim CEO Ross Levinsohn told CNBC

The winning bid is estimated to be as high as $6 billion, according to SunTrust Robinson Humphrey (STI) analyst Bob Peck.

"I think Bob's done probably the best work from an analyst's standpoint on this whole escapade," Levinsohn said. 

Levinsohn expects the company to trade in at $3.5 billion to $4.5 billion depending on what assets are included in the deal.

This year Yahoo is estimating $750 million EBITDA, $300 million of EBITDA will go to Yahoo Japan, IP, and licensing which leaves the company at about $450 million EBIT, Levinsohn said citing Bob Peck's notes.

Potential buyers do have synergy and may pay a little bit higher for the Yahoo! name but Levinsohn doesn't expect it to sell for more than $5 billion.

"I understand why the board and the company went the direction it went. We can look back now and say, it just didn't work," Levinsohn said.

Regardless of who runs Yahoo, Levinsohn says there's an incredible amount of work to be done.

Yahoo CEO Marissa Myers is taking a lot of the heat for Yahoo's poor performance. But Levinsohn says the board and senior management around her at the time are also to blame.

Shares of Yahoo are up 0.21% to $37.80 this afternoon.

However, as a counter to these strengths, TheStreet Ratings team also finds weaknesses including deteriorating net income, disappointing return on equity and feeble growth in the company's earnings per share.
