Houston-based Archrock Partners has named Stephanie Hildebrandt as senior vice president and general counsel, effective Aug. 7. Archrock supplies natural gas contract compression services.

Hildebrandt joins a company that is under investigation by the U.S. Securities and Exchange Commission and the U.S. Department of Justice. According to its latest quarterly report to the SEC on Tuesday, Archrock is being investigated for “previously disclosed errors and possible irregularities at one of our former international operations,” that being Exterran Corp.

“We have been assisting Exterran Corp. in responding to a subpoena for documents related to the restatement of prior period consolidated and combined financial statements and related disclosures and compliance with the U.S. Foreign Corrupt Practices Act (FCPA), which are also being provided to [the DOJ] at its request,” the filing notes.

The company said both it and Exterran are cooperating with the investigation. 

At Archrock, Hildebrandt replaces general counsel Donald Wayne, who resigned March 31 to become GC at fellow Houston energy contracting company Quanta Services Inc. In May, Wayne accepted a one-year, $10,000 consulting contract with Archrock to help facilitate the transition to a new GC, according to filings with the SEC.

Prior to joining Archrock, Hildebrandt most recently served as a partner with global business law firm Norton Rose Fulbright, with a practice focused on corporate governance, energy transactions and mergers and acquisitions.

The Archrock role is not her first GC job. Hildebrandt previously worked as the general counsel of Enterprise Products Partners, an oil and energy company also based in Houston, from 2010 to 2014. According to the company, she held various other roles as well, including deputy counsel from 2004.

Hildebrandt was also an attorney for El Paso Corp./ GulfTerra Energy Partners from 2001 to 2004, and an attorney for Texaco Inc. from 1989 to 2001.

“With her extensive experience in energy services and in master limited partnerships, Stephanie will bring significant value to our company,” said a statement by Bradley Childers, Archrock’s president and CEO.

Archrock, according to its quarterly financial report, reported a net loss of $4 million in the second quarter of 2017, following a first-quarter loss of $14 million. The company blamed the down energy economy, and Childers indicated he expected an upturn by the end of 2017.
