Willbros Announces Multiple Awards Valued at $151

• Executed contracts total $106 million  
• Pipeline written notification of award for $45 million

HOUSTON, March 07, 2017 (GLOBE NEWSWIRE) -- Willbros Group, Inc. (NYSE: WG ) today announced that it has executed two contracts and finalized an extension of another Master Service Agreement (“MSA”) in Canada. These awards have an estimated value of $106 million and will be added to backlog during the first quarter of 2017:

• Our Utility Transmission & Distribution segment has been awarded a $37 million contract to construct a 110-mile transmission line for a new client. Our Chapman business unit will commence construction immediately and anticipates completion by the end of 2017.  
• In addition to the five year MSA award announced in December 2016, the Construction & Maintenance business unit in our Canada segment was awarded a three-year extension on an existing MSA contract to continue maintenance work in the Alberta oil sands region with an estimated value of $56 million over the duration of the extension. Work under this extension commenced March 1, 2017.  
• Also, our Canada segment finalized the $13 million contract to construct a 48-inch, eight kilometer pipeline that was announced as a written notice of award in December 2016. Construction has begun and is anticipated to be completed during the third quarter of 2017.

Further, a unit of our Oil & Gas segment has received a written notification of award to construct a pipeline in the Northeast. Terms for this $45 million award are near agreement and we anticipate contract signing to occur within the next week. Work is expected to commence in mid-March and is anticipated to be completed during the third quarter of 2017.

Mike Fournier, President and CEO, said “These awards, coupled with the increase in our Q4 2016 backlog, reflect the ongoing efforts across the organization to build quality backlog. While a significant portion of this work will be completed during Q2 and Q3 2017, we sense strong markets for our services and continue to see bidding opportunities that look appealing.

The above awards are in addition to our January 2017 twelve-month and total backlog amounts of $426 million and $776 million, respectively.”
