Williams Seeks Control of Access Midstream for $3 Billion

Williams Cos. is in advanced talks to buy control of Access Midstream Partners LP for about $3 billion, according to people with knowledge of the matter, in a move to boost growth for the fourth-largest U.S. pipeline firm.

Williams would buy the stake from Global Infrastructure Partners, which owns almost one-third of Access Midstream as well as half of its general partner, the people said, asking not to be identified discussing private information. An agreement could be announced as soon as next week, the people said.

The deal is intended to accelerate Williams’ expansion prospects, four months after the company avoided a potential proxy fight by giving board seats to activist investors Keith Meister and Eric Mandelblatt, who had urged it to consider “strategic combinations.”

In 2012, Williams bought about 25 percent of Tulsa, Oklahoma-based Access and half of its general partner -- called Access Midstream Partners GP LLC. The latest deal would have it buying the other 50 percent of the general partner, which manages Access’s operations, determining how it will borrow and invest, among other things, the people said.

Access, with a market capitalization of about $13.2 billion, provides oil and natural gas gathering services to Chesapeake Energy Corp., Anadarko Petroleum Corp. and other major exploration companies, according to its 2013 annual report. Its shares are up about 16 percent this year.

MLP Structure

Jack Cowell, a spokesman for Global Infrastructure Partners and Chris Callahan, a spokesman for Access Midstream, declined to comment. Tom Droege, a spokesman for Williams, didn’t respond to phone or e-mail messages seeking comment.

Access is structured as a master-limited partnership, so it pays no federal income taxes as long as it pays out most of its cash to shareholders. The stake in Access’s general partner means Williams is entitled to an increasing share of cash flow as it grows and can collect dividends on the partnership’s common units.

In addition to its stake in the closely held general partner, Global Infrastructure owns more than 31 percent of Access -- including Class B shares -- according to Access’s annual report.
