(NYSE:HEP) and Holly Corporation (“Holly”)(NYSE:HOC) today announced the acquisition by Holly Energy from Holly of a newly constructed 16” pipeline connecting Holly’s refining facilities in Lovington, New Mexico to Holly’s refining facilities in Artesia, New Mexico.

The purchase price for this pipeline was $34.2 million which was paid in cash. The acquisition was financed through HEP’s revolving credit facility.

“We are pleased that Holly Energy was able to acquire another key logistic asset from Holly. This pipeline will support expanded volumes from the recent Navajo Refinery expansion and contribute additional revenues for Holly Energy,” said Matt Clifton, Chairman and CEO of Holly and Holly Energy.
