Dallas, TX – February 28, 2019–  Primoris Services Corporation (NASDAQ GS: PRIM) (“Primoris” or “Company”) today announced financial results for its fourth quarter and year ended December 31, 2018.

The Company also announced that on February 26, 2019 its Board of Directors declared a $0.06 per share cash dividend to stockholders of record on March 29, 2019, payable on or about April 15, 2019. 

David King, President and Chief Executive Office of Primoris, commented, “2018 was another record year for Primoris, as we achieved our strategic goal of growing revenue to nearly $3 billion by 2019 and achieved our largest annual revenue, operating income, and EPS in the Company’s history while growing our MSA revenue to all-time records. As we continue to execute our strategic plan and growth initiatives, we are well positioned to continue delivering value to our shareholders. The Power & Industrial segment was particularly strong, with our teams in the field delivering impressive margins on multiple projects. The Utilities & Distribution segment continued their record of steady growth and geographic expansion, and combined with our new Transmission & Distribution segment, our MSA backlog has reached an all-time high. We have grown our presence in the Southwest small diameter pipeline and field services markets, and our Pipeline & Underground segment performance remains solid in the face of permitting challenges and weather headwinds. The Civil segment has made progress on legacy projects and we have the right team in place for successful execution on new awards.”

Mr. King continued, “We believe we are well positioned to continue to capitalize on the increasing need for infrastructure services that allow for multi-year growth cycles in all of our business segments. As Primoris has grown revenue and backlog, we have also achieved our goal of containing overhead spending, with SG&A as a percentage of revenue now at its lowest level in four years. We controlled spending without sacrificing our focus on safety, or quality, and we are immensely proud of our total recordable incident rate of 0.51 for the year, which is well below the industry average. As we look at the opportunities in 2019, our gas and electric MSA

work provides a reliable recurring base of revenue on which we can build continued growth.  While the timing of large project work can be uncertain, we believe we have the right balance between recurring and project based opportunities. Our business units are working together to pursue projects across the renewable, petrochemical, utilities, power, and refining industries. We are encouraged by our client’s staunch support for a major pipeline project that has faced considerable legal challenges, and opportunities for small diameter pipeline work remain strong. We have a breadth of opportunity across our end markets to support another robust year for Primoris in 2019.”

2018  FOURTH QUARTER RESULTS OVERVIEW

Revenue for the fourth quarter 2018 increased by $298.7 million, or 51.6%, compared to the fourth quarter 2017.  The increase was primarily due to incremental revenue in the fourth quarter 2018 from acquisitions and organic growth in our Pipeline segment.  Gross profit in the fourth quarter 2018 increased by $34.8 million, or 50.8%, compared to fourth quarter 2017. The increase was primarily due to incremental gross profit from acquisitions, the settlement of a disputed receivable related to a project completed in 2014, and the increased revenue in the Pipeline segment.  Gross profit as a percentage of revenue was 11.8% in both the 2018 and 2017 fourth quarters.

Power, Industrial, & Engineering Segment (“Power”):  Revenue in the Power segment increased by $15.7 million in the fourth quarter 2018, compared to the same period in 2017.  The increase in revenue was primarily due to increases from an oil field maintenance services program and a refinery project, both in Southern California, as well as revenue from the Canadian operations of the Willbros acquisition.  Revenue gains were partially offset by declining revenue from the Carlsbad joint venture, as that project achieved substantial completion in the fourth quarter 2018.   In addition, we collected on a disputed receivable in the fourth quarter 2018 related to a major project completed in 2014, which resulted in recognizing revenue of approximately $11.9 million.  Segment gross profit increased by $19.9 million in the fourth quarter 2018, compared to the same period in 2017, primarily from the Southern California refinery project and the Carlsbad joint venture project, as well as the collection of the disputed receivable.  Gross profit as a percentage of revenue increased to 18.5% in the fourth quarter 2018, compared to 8.1% in the same period in 2017.  The increase in gross profit as a percentage of revenue is primarily due to strong performance and favorable margins realized by our Carlsbad joint venture project, as well as the collection of the disputed receivable. We do not expect profit margins to remain at  this elevated level in 2019.

Pipeline & Underground Segment (“Pipeline”):  Revenue in the Pipeline segment increased by $166.5 million in the fourth quarter 2018, compared to the same period in 2017, primarily due to increased revenue from large pipeline projects in the Mid Atlantic and West Texas. Segment gross profit increased by $10.5 million in the fourth quarter 2018, compared to the same period in 2017, primarily as the result of the increased revenue.  Gross profit as a percentage of revenue decreased to 10.0% in the fourth quarter 2018, compared to 19.8% in the same period in 2017.  The decrease in gross profit as a percentage of revenue is primarily due to the completion of a pipeline project in West Texas and the rental of large diameter pipeline equipment to third parties in the fourth quarter 2017.

Utilities & DistributionSegment (“Utilities”):   Revenue in the Utilities segment increased by $7.5 million in the fourth quarter 2018, compared to the same period in 2017.  Revenue increased with major utility customers in California and the MidWest.  Segment gross profit decreased by $3.5 million in the fourth quarter 2018, compared to the same period in 2017, primarily as a result of a wet December and project mix.  Gross profit as a percentage of revenue decreased to 13.8% in the fourth quarter 2018, compared to 15.8% in the same period in 2017. The decline in gross profit as a percentage of revenue is primarily due to weather and mix.

Transmission & DistributionSegment (“Transmission”):  The Transmission segment was created in connection with the acquisition of Willbros. All revenue and gross profit figures represent results from June 1, 2018, the acquisition date, to December 31, 2018.

Civil Segment (“Civil”):   Revenue in the Civil segment decreased by $13.9 million in the fourth quarter 2018, compared to the same period in 2017.  The decreased revenue primarily came from the decision to exit an airport project in the second quarter of 2018, the substantial completion of a large petrochemical plant project in 2017 and decreases from Arkansas DOT projects.  Segment gross profit decreased by $4.4 million in the fourth quarter 2018, compared to the same period in 2017, primarily as the result of decreased revenue. Gross profit as a percentage of revenue decreased to 1.9% in the fourth quarter 2018, compared to 5.3% the same period in 2017. The decrease in gross profit as a percentage of revenue is primarily due to the substantial completion of a large petrochemical plant project in 2017.

OTHER INCOME STATEMENT INFORMATION

Selling, general and administrative (“SG&A”) expenses were $50.0 million during the fourth quarter 2018, an increase of $6.4 million, compared to the fourth quarter 2017.  SG&A expense as a percentage of revenue decreased to 5.7% compared to 7.5% for the corresponding period in 2017 due to increased revenue.

The effective tax rate on income attributable to Primoris (excluding noncontrolling interests) was 25.0% for full year 2018. The rate differs from the U.S. federal statutory rate of 21% primarily due to state income taxes, investment tax credits, and nondeductible components of per diem expenses.

OUTLOOK

Based on an expected third quarter 2019 remobilization date for a major pipeline project in backlog, anticipated MSA spending, and an expected corporate tax rate of 28%, the Company estimates that for the fiscal year ending December 31, 2019, net income attributable to Primoris is expected to be between $1.60 and $1.80 per fully diluted share.
