Exhibit 99.1

Primoris Services Corporation Reports Second Quarter 2021 Results

Dallas, TX – Aug. 3, 2021– Primoris Services Corporation (NASDAQ GS: PRIM) (“Primoris” or “Company”) today announced financial results for its second quarter ended June 30, 2021 and updated the Company’s outlook.

For the second quarter 2021, Primoris reported the following highlights:

● Revenue of $881.6 million

o Utility Segment revenue up 25 percent

o Energy/Renewables Segment revenue up 20 percent

● Net income attributable to Primoris of $36.3 million

● Fully diluted earnings per share of $0.67

● Backlog of $2.9 billion as of June 30, 2021

2021 Year-to-date highlights:

● Record revenue of $1.7 billion

● Record Master Service Agreements (“MSA”) Backlog of $1.5 billion, 52 percent of total backlog

● Fully diluted earnings per share of $0.81

“Our outstanding revenue performance in the utility and energy/renewables markets demonstrates that our investment in these areas over the past several years is already paying off,” said Tom McCormick, President and Chief Executive Officer of Primoris. “Our record year-to-date revenue of $1.7 billion is up more than $48 million compared to where we were last year, despite the winter storm that hit Texas in the first quarter and historically wet weather conditions in the second quarter that pushed some of our revenue further out in the year. Our strategic focus on master service agreements is also showing results; 52 percent of our current backlog is MSA based work, a record level.”

Summarizing the segment results for the quarter, McCormick noted: “Our strong project execution continued to reap benefits throughout the second quarter. Our Utility Segment led the revenue growth with a 25 percent increase compared to the same period in 2020, primarily due to the Future Infrastructure acquisition and increased activity with a significant customer in California. Solar projects continued to drive our Energy/Renewables Segment revenue during the quarter. This segment increased revenue by 20 percent and gross profit by 84 percent compared to the same period of 2020. As expected, our Pipeline Services Segment revenue declined, although our gross profit increased 15 percent and our gross profit, as a percentage of revenue, increased to 26 percent.”

2021 Second Quarter Results

Revenue was $881.6 million for the three months ended June 30, 2021, a decrease of $26.6 million, or 3 percent, compared to the same period in 2020. The decrease was primarily due to lower revenue in the Pipeline segment, partially offset by growth in the Energy/Renewables and Utilities segments, including $72.7 million from the acquisition of Future Infrastructure Holdings, LLC (“FIH”). Gross profit was $113.0 million for the three months ended June 30, 2021, an increase of $12.1 million, or 12 percent, compared to the same period in 2020. The increase was primarily due to the acquisition of FIH ($10.7 million) and an increase in margins from legacy operations, partially offset by a decrease in revenue from the Company’s legacy operations. Gross profit as a percentage of revenue increased to 13 percent for the three months ended June 30, 2021, compared to 11 percent for the same period in 2020.

Beginning with the first quarter of 2021, the Company consolidated and reorganized its operating segments. The three segments are: Utilities, Energy/Renewables and Pipeline Services. Revenue and gross profit for the segments for the three and six months ended June 30, 2021 and 2020 were as follows:

Utilities Segment (“Utilities”): Revenue increased by $85.3 million, or 25 percent, for the three months ended June 30, 2021, compared to the same period in 2020, primarily due to the FIH acquisition ($72.7 million) and increased activity with a significant utility customer in California. These amounts were partially offset by decreased activity with a utility customer in the Midwest as well as the impact of customer material delays. Gross profit for the three months ended June 30, 2021 decreased by $7.0 million, or 13 percent, compared to the same period in 2020, primarily due to lower margins from the Company’s legacy operations, partially offset by the incremental impact of the FIH acquisition ($10.7 million). Gross profit as a percentage of revenue decreased to 12 percent during the three months ended June 30, 2021, compared to 16 percent in the same period in 2020, primarily due to unfavorable weather conditions and customer material delays experienced in 2021, as well as strong performance and favorable margins realized on projects in the Southeast in 2020.

2

Energy and Renewables Segment (“Energy/Renewables”): Revenue increased by $56.5 million, or 20 percent, for the three months ended June 30, 2021, compared to the same period in 2020, primarily due to increased renewable energy activity ($69.8 million), partially offset by the substantial completion of an industrial project in Texas in the first half of 2020. Gross profit for the three months ended June 30, 2021, increased by $15.1 million, or 84 percent, compared to the same period in 2020, primarily due to higher revenue and margins. Gross profit as a percentage of revenue increased to 10 percent during the three months ended June 30, 2021, compared to 7 percent in the same period in 2020, primarily due to higher costs associated with a liquified natural gas plant project in the northeast in 2020.

Pipeline Services (“Pipeline”): Revenue decreased by $168.4 million, or 58 percent, for the three months ended June 30, 2021, compared to the same period in 2020. The decrease is primarily due to the substantial completion of pipeline projects in 2020 ($188.6 million), partially offset by progress on a pipeline project in Texas that began in the second half of 2020. Gross profit for the three months ended June 30, 2021 increased by $3.9 million, or 15 percent, compared to the same period in 2020, primarily due to higher margins, partially offset by lower revenue. Gross profit as a percentage of revenue increased to 26 percent during the three months ended June 30, 2021, compared to 9 percent in the same period in 2020, primarily due to the favorable impact from the closeout of multiple pipeline projects in 2021.

Other Income Statement Information

Selling, general and administrative (“SG&A”) expenses were $57.7 million during the three months ended June 30, 2021, an increase of $6.3 million, or 12 percent compared to 2020, primarily due to $7.6 million of incremental expense from the FIH acquisition during the period. SG&A expense as a percentage of revenue increased to 6.6 percent compared to 5.7 percent for the corresponding period in 2020, primarily due to increased expense as the Company integrates FIH into its operations.

Transaction and related costs were $0.5 million for the three months ended June 30, 2021, consisting primarily of professional fees paid to advisors associated with the FIH integration. No transaction and related costs were incurred for the three months ended June 30, 2020.

Interest expense for the three months ended June 30, 2021, increased compared to the same period in 2020 primarily due to higher average debt balances from the borrowings incurred related to the FIH acquisition, partially offset by a favorable impact from the change in the fair value of the interest rate swap. During the three months ended June 30, 2021, the Company had a $1.0 million unrealized gain on the change in the fair value of the Company’s interest rate swap agreement, compared to a $0.1 million unrealized gain in 2020.

The Company recorded income tax expense for the three months ended June 30, 2021 of $13.6 million compared to expense of $13.5 million for the three months ended June 30, 2020. The effective tax rate on income attributable to Primoris (excluding noncontrolling interests) was 27.3 percent for the three months ended June 30, 2021. The effective tax rate on income attributable to Primoris (excluding noncontrolling interest) is expected to be 27.5 percent for 2021. The 2021 rate differs from the U.S. federal statutory rate of 21.0 percent primarily due to state income taxes and nondeductible components of per diem expenses.

Outlook

Balancing the ongoing uncertainty surrounding the COVID-19 pandemic with the expected growth in operations, Primoris estimates that for the year ending December 31, 2021, net income attributable to Primoris will be between $2.30 and $2.50 per fully diluted share. The per share range takes into count the dilution from the additional shares issued under the Company’s secondary offering during the first quarter of 2021. The Company is targeting SG&A expense as a percentage of revenue in the low-to-mid six percent range for full year 2021. Primoris expects its SG&A range will decrease in 2022 upon completion of its integration of FIH. The Company estimates capital expenditures for the remainder of 2021 in the range of $20 to $40 million. The Company’s targeted gross margins by segment are as follows: Utilities in the range of 12 to 14 percent; Energy/Renewables in the range of 9 to 12 percent; and Pipeline Services in the range of 9 to 13 percent.

The guidance provided above constitutes forward-looking statements, which are based on current economic conditions and estimates, and the Company does not include other potential impacts, such as changes in accounting or unusual items. Supplemental information relating to the Company’s financial outlook is posted in the Investor Relations section of the Company’s website at www.primoriscorp.com.

Segment	Fixed Backlog		MSA Backlog		Total Backlog
Utilities	$	61	$	1,343	$	1,404
Energy/Renewables		1,089		116		1,205
Pipeline		226		35		261
Total	$	1,376	$	1,494	$	2,870

At June 30, 2021, Fixed Backlog was $1.4 billion and MSA Backlog was $1.5 billion. Total Backlog at the end of the second quarter 2021 was $2.9 billion. MSA Backlog represents estimated MSA revenue for the next four quarters. The Company expects that during the next four quarters, the Company will recognize as revenue approximately 86 percent of the total backlog at June 30, 2021, comprised of backlog of approximately: 100 percent of Utilities; 73 percent of Energy/Renewables; and 73 percent of Pipeline.

Backlog, including estimated MSA revenue, should not be considered a comprehensive indicator of future revenue. Revenues from certain projects, such as cost reimbursable and time-and-materials projects, do not flow through backlog. At any time, any project may be cancelled at the convenience of customers.

Liquidity and Capital Resources

At June 30, 2021, the Company had $178.0 million of unrestricted cash and cash equivalents. The Company had no outstanding borrowings under the revolving credit facility, commercial letters of credit outstanding were $48.9 million and the available borrowing capacity was $151.1 million.
