Enterprise Products Partners LP (NYSE: EPD) and Oiltanking Partners LP (NYSE: OILT) completed Oiltanking’s merger with an Enterprise subsidiary, the companies said Feb. 13.

Oiltanking unitholders approved the merger during a unitholder meeting that day, the companies added. About 99.87% of Oiltanking’s common units voted in favor. This amount included about 66% of the outstanding units owned by subsidiary Enterprise Products Operating LLC.

The total number of units that voted for the merger represents about 92.18% Oiltanking’s total outstanding common units.

Holders of a majority of Oiltanking’s outstanding units were required to approve and adopt the agreement.

Oiltanking unitholders are entitled to receive 1.3 Enterprise common units for each Oiltanking common unit. Cash will be paid to Oiltanking’s unitholders instead of fractional units, and Oiltanking’s common units will stop trading on the New York Stock Exchange because Oiltanking is now a subsidiary of Houston-based Enterprise, which will continue to trade under the ticker “EPD.”

The two-step acquisition began on Oct. 1, 2014.

“The completion of this merger is a significant milestone for our partnership,” said Michael A. Creel, CEO of Enterprise’s general partner. “Our ownership of Oiltanking Partners provides new avenues for growth and adds important marine terminals along the Texas Gulf Coast to our portfolio of assets. The combination of Enterprise’s system of midstream assets and Oiltanking Partners’ access to waterborne markets and crude oil and petroleum products storage assets will extend and broaden our midstream energy services business.”
