NEW YORK (TheStreet) -- Williams Cos. (WMB) - Get Williams Companies, Inc. Report stock is down by 5.78% to $15.32 in early-afternoon trading on Thursday, after rival pipeline company Energy Transfer Equity (ETE) slashed its expectations for the companies' proposed $14 billion merger. 

Energy Transfer now believes that the base case for earnings before interest, taxes, depreciation and amortization from commercial synergies from the deal will be around $170 million a year by 2020, down from previous forecasts of more than $2 billion, according to an SEC filing, Reuters reports.

The outlook assumes that oil prices will range between $32.92 to $44.31 per barrel in 2020. However, if oil prices rally between $53.97 and $64.26 per barrel by then, EBITDA could be closer to $590 million a year.

Additionally, Energy Transfer plans to grant certain awards totaling roughly 10% of outstanding common shares of Energy Transfer Corp., which Energy Transfer has created to purchase Williams, Reuters notes.

Williams shareholders would consequently hold roughly 75% of outstanding shares of Energy Transfer Corp., down from about 81% before the grant.
