Williams Cos. (WMB) raised its bid for Texas pipeline company Southern Union Co. (SUG) to about $5.6 billion in cash in the latest round of a takeover battle with Energy Transfer Equity LP (ETE), topping its sweetened cash-and-stock offer of $5.1 billion for Texas pipeline company.

Williams is now offering $44 a share, an increase of $5 a share from its bid last month of $39 a share, or about $5 billion. The company had been expected to raise its offer.

Southern Union shares were up 4.3% at $43.39 in recent premarket trading.

"We are more convinced than ever of the strategic and financial benefits of Williams' acquisition of Southern Union," Williams' President and Chief Executive Officer Alan Armstrong said. "Based on the terms of our premium-value, all-cash proposal, we are confident that Southern Union's Board of Directors will determine its superiority to the Energy Transfer agreement."

Neither Southern Union not Energy Transfer was immediately available for comment.

Energy Transfer and Southern Union last week had set a deal initially valued at $40 a share. Energy Transfer also agreed to sell some assets in order for the deal to pass muster with antitrust regulators. The companies raised the breakup fee for their agreement to $162.5 million from $92.5 million in the original agreement, another indication that a higher bid was expected.

Both companies had expressed willingness to assume Southern's debt, totaling $3.7 billion.

Williams on Thursday said its proposal isn't subject to financing conditions and that it is committed to closing the transaction "on a timeline consistent with the proposed Energy Transfer transaction."

Williams shares were down 1% at $28.50 in recent premarket trading. Energy Transfer's common units closed Wednesday at $44.78 and were inactive premarket.
