"Having achieved this important milestone, we look forward to closing on September 25 and moving forward as one company with a continued commitment to creating value for our shareholders."

"We appreciate that investors recognize the combination with ONEOK captures full value for Magellan unitholders and are grateful for their constructive engagement over the past few months," said Aaron Milford, Magellan chief executive officer.
