(“Williams Companies”) (NYSE: WMB), in a transaction valued at approximately $13.8 billion.

Under the terms of the agreement, shareholders of Williams Partners will receive 1.115 shares of Williams Companies for each share of Williams Partners common stock owned.  Based on Williams Companies’ closing price on May 12, 2015, Williams Partners shareholders would have received compensation valued at approximately $55.86 per share.
