MELBOURNE, Reuters – Woodside (OTC) Petroleum is not expecting heavy selling by BHP Group’s (NYSE:) shareholders if Woodside’s purchase of BHP’s oil business proceeds in June. Chief Executive Meg O’Neill stated Monday.

Woodside shareholders have the opportunity to vote on Thursday for a merger worth $40 billion to make Woodside Energy a global top 10 independent oil-and gas producer. BHP shareholders will own a 48% share in the new group, which will be known as Woodside Energy.

Investors who hold BHP shares, but not Woodside share currently have concerns. They may try to sell the Woodside shares that will be given in this deal.

O’Neill stated that her discussions with shareholders of BHP were “really good” and she was able to explain the expected returns, the capital management framework and strength of the balance sheets.

Woodside also spoke to U.S. investors in an effort to emphasize the differences it has with its peers. These independent peer companies are focused on oil shale, while Woodside is focused on offshore oil and gas, and liquefied petroleum (LNG), assets.

“At end of day, we believe that there will be demand for Woodside share that exceeds the availability. O’Neill spoke to reporters at an oil-and gas conference. “So we believe the flowback risk has been largely minimized.”

However, it is important to note that this is an enormous transaction. As we are issuing large numbers of shares, we anticipate some volatility over the coming months. It won’t last, but I think so.

According to her, only a few BHP shareholders live in countries where Woodside shares are not permitted.
