INDIANAPOLIS, May 9, 2022 – Infrastructure and Energy Alternatives, Inc. (Nasdaq: IEA) (“IEA” or the “Company”), a leading infrastructure company with renewable energy and specialty civil expertise, today announced results for the first quarter 2022.

(As compared to the First Quarter 2021)

Record Total Revenues of $360.1 million, +30.3% y/y
Record Renewables Backlog of $2.1 billion, +7.0% y/y
Record Total Backlog of $2.9 billion, +10.1% y/y
Net Loss of ($27.1) million, versus a Net Loss of ($20.4) million
Adjusted EBITDA of ($17.1) million, versus $3.4 million
Increased 2022 Revenue Guidance to between $2.3 billion and $2.5 billion

Revenue increased by 30% on a year-over-year basis in the first quarter 2022, supported by growth across both the Renewables and Specialty Civil segments. Renewables segment revenue increased 35% on a year-over-year basis in the first quarter, and within Renewables, first quarter solar revenue increased by 275% and represented more than half of total Renewables revenues, while wind revenue declined by 20%. Specialty Civil segment revenue increased 21% on a year-over-year basis in the first quarter, driven by continued strength in environmental revenue, including an increase in projects under construction compared to the prior year and steady growth in heavy civil, partially offset by a decline in rail revenue.

For the three months ended March 31, 2022, the Company reported a net loss of ($27.1) million, or ($0.56) per diluted share, versus a net loss of ($20.4) million, or ($0.91) per diluted share, in the first quarter 2021.

Adjusted EBITDA declined to ($17.1) million in the first quarter 2022, versus $3.4 million in the prior-year period. First quarter Adjusted EBITDA was impacted by lower project gross margins in both the Renewables and Specialty Civil segments, due to inflationary pressures on project costs, particularly in our Renewables business, combined with increased close out costs on certain heavy civil projects. For a reconciliation of net income to Adjusted EBITDA, please see the appendix to this release.

As of March 31, 2022, total backlog increased to $2,946 million, versus $2,916 million at the end of the fourth quarter 2021. Next twelve-month backlog was $2,085 million, a decline from $2,152 million at the end of fourth quarter 2021, but still up 12.6% from the prior-year period.


“The IEA team delivered 30% year-over-year organic revenue growth, achieving record total revenue in the first quarter and record total backlog. I am happy to report that demand is strong across both our Renewables and Specialty Civil segments,” stated JP Roehm, President and CEO of IEA. “Markets for our core renewables and environmental services remain robust, while bidding activity in our heavy civil and rail businesses accelerated into the second quarter.”

“Despite strong revenue growth, our margins were adversely impacted by inflationary costs for fuel, supply chain cost increases and delays, and availability of local labor,” continued Roehm. “While we expect that many of these challenges will remain throughout the rest of 2022, we believe that we will see improvements to our project margins and overall profitability, and continue to expect record revenue and Adjusted EBITDA for the full year. It’s worth noting first quarter for our business has historically been our slowest, with projects ramping up quickly in the following three quarters, we expect that cadence to continue this year.”

“Our solar customers are effectively navigating market-wide concerns regarding both the availability and rising cost of panels,” noted Roehm. “At this juncture, many of our solar customers have successfully sourced panel inventory and anticipate limited, if any, impact from current market volatility. In some instances where panels remain on order, we are being asked to complete civil and mechanical work ahead of panel delivery, to ensure that projects remain on-schedule or experience only modest delays. Across the organization, we continue to have a strong backlog of additional projects to fill in any gaps in project cadence and support full utilization of our teams, which provides further confidence to our full-year outlook.”

“Entering 2022, we recognized the potential for some near-term margin headwinds and considered these factors in our full-year 2022 financial guidance,” continued Roehm. “These headwinds were exacerbated in the first quarter because of rapid increases in fuel costs primarily resulting from the unexpected Russian invasion of Ukraine and the recently announced Department of Commerce investigation. As a result of our first quarter results, our confidence in our current backlog and the status of panel availability for our solar projects, we are updating our full-year 2022 financial guidance by increasing our revenue guidance to a range of $2.3 to $2.5 billion, while maintaining our Adjusted EBITDA guidance range of $140 million to $150 million. This change reflects the reality of current margin headwinds impacting our business, which we anticipate will be offset with higher revenue. We will continue to monitor the factors that could impact our ability to achieve our previously forecasted results.”

“Our core investment thesis, which highlights the benefits of our diverse, renewables-weighted revenue mix, strong customer relationships, track record of successful execution and simplified capital structure, remains unchanged,” concluded Roehm. “IEA continues to grow across all sectors and is seeing particularly strong growth in our solar business. We believe that we are well-equipped to overcome the near-term margin headwinds that impacted our first quarter performance, while remaining on-track to achieve another year of strong performance, highlighted by record revenue and EBITDA.”


IEA has continued to execute on its core strategic priorities, while positioning the organization for sustained, profitable growth and long-term value creation. The Company’s strategic priorities and recent successes against these strategies are as follows:

Develop a leading position of scale within markets where IEA is competitively advantaged. IEA intends to leverage its technical expertise, geographic reach, scale, and strong customer relationships across its key business lines to drive continued backlog growth and market share gains through a combination of organic and inorganic growth. Over the last twelve months, IEA generated total organic revenue growth of 29%, while the renewables segment revenue increased 42% on an organic basis, versus the prior twelve-month period.

Capitalize on favorable long-term fundamentals within renewables, environmental, and infrastructure markets. In 2021, approximately 70% of IEA’s revenue was derived from solar and wind-related EPC services. Over the next five years, IEA expects more than 100 GW of new utility-scale solar capacity to be installed within the United States, an increase of more than 80% versus the prior, five-year period. Onshore wind installations are also anticipated to remain strong, with 110 GW of new, installed capacity expected to be online by 2030. Within the Company’s non-renewable, environmental services markets, demand conditions are robust, and we believe there is a multi-decade potential opportunity of $50-150 billion for coal ash remediation. With a strong track record of execution, experienced skilled work force, and broad geographic presence, IEA is well-positioned to take advantage of these trends as highlighted by our recent backlog strength.

Maintain bidding discipline, drive economies of scale, and execute on operational efficiencies to support margin expansion. IEA intends to pursue higher-value, margin-enhancing opportunities, while leveraging its size and scale to deliver exceptional value for our customers. The Company entered the solar business in 2019 and believes that, while challenged in 2022, margins will continue to improve as the business grows and realizes the benefits of economies of scale.

Further simplify capital structure, while maintaining a strong balance sheet and sufficient liquidity to support growth. During 2021, IEA undertook a capital structure simplification plan that resulted in lower debt costs, a more flexible capital structure, and reduced leverage. As part of this plan, in November 2021, IEA’s Board of Directors authorized a program to repurchase up to $25 million of outstanding warrants (Nasdaq: IEAWW) to further streamline the Company’s capital structure. Since announcing this program, IEA has repurchased nearly 65% of the outstanding warrants at a total cost of $14.8 million through the end of Q1 2022. The program will end no later than the expiration of the warrants on March 26, 2023. IEA intends to exercise a disciplined approach to repurchases until the program is complete or the warrants expire. As of March 31, 2022, IEA had more than $161.4 million in available cash and availability on its credit facilities to support the growth of the business.

Pursue disciplined capital allocation strategy. IEA intends to prioritize capital allocation to optimize its return on invested capital. The Company expects to continue to invest in organic growth initiatives by expanding product and services offerings to better serve customers, further developing industry-leading technical expertise, and growing its skilled labor workforce. The Company also intends to pursue complementary, bolt-on acquisitions that further strengthen the Company’s position in high-growth and attractive end markets, increase its service capabilities in adjacent markets, expand its geographic presence and enhance its blended margin profile.


Revenue and Gross Profit by segment was as follows:

Specialty Civil2,529 2.2 %4,361 4.5 %
  Total gross profit$3,830 1.1 %$16,541 6.0 %

Renewables Segment revenue totaled $243.6 million during the first quarter 2022, an increase of 35.1% compared to the prior year. The strength in the Company’s solar business continued, with revenues up nearly four-fold during the first quarter, while wind revenues declined during the first quarter. Renewables Segment gross profit was $1.3 million, or 0.5% of revenue, for the first quarter of 2022, compared to $12.2 million, or 6.8% of revenue, for the same period in 2021. The decrease in gross profit margin percentage for the Renewables Segment was primarily due to the inflationary impact of labor, supply chain, fuel, and certain commodities which increased estimated future costs and decreased project margins; and to a lesser extent, increased training costs as the Company continues to grow our labor force to execute our backlog.

Specialty Civil Segment revenue totaled $116.5 million, an increase of 21.3% year-over-year, due to growth in environmental and heavy civil. While rail revenues remained under pressure during the first quarter, bidding activity has started to improve. Specialty Civil Segment gross profit was $2.5 million, or 2.2% of revenue, for the first quarter of 2022, as compared to $4.4 million, or 4.5% of revenue, for the same period in 2021. The decrease in gross profit percentage was primarily due to inflationary pressures discussed above. Additionally, we recorded increased close out costs related to certain projects.


As of March 31, 2022, the Company had $28.7 million of cash and cash equivalents and total debt of $366.5 million, consisting of the $300.0 million senior unsecured notes, $3.0 million of commercial equipment notes, and $63.5 million of obligations, exclusive of associated interest, recognized under various finance leases for equipment. At the end of the quarter, the Company had $132.7 million of availability under its credit facility, net of letters of credit. Combined with cash, total liquidity was $161.4 million.


IEA defines “backlog” as the amount of revenue the Company expects to realize from the uncompleted portions of existing construction contracts, including new contracts under which work has not begun and awarded contracts for which the definitive project documentation is being prepared. Backlog is not a term recognized under GAAP, although it is a common measurement used in the Company’s industry. IEA’s methodology for determining backlog may not be comparable to the methodologies used by others. See Item 1A. Risk Factors in the Company’s Annual Report for a discussion of the risks associated with IEA’s backlog.

The following table summarizes the Company’s backlog by segment for the periods below:

(in millions)
SegmentsMarch 31, 2022December 31, 2021
Renewables$2,084.8 $2,034.8 
Specialty Civil861.2 881.3 
  Total$2,946.0 $2,916.1 

Total backlog at March 31, 2022 was $2.9 billion, an increase of $270.2 million, or 10.1% compared to the year-ago period. Renewables Segment backlog at March 31, 2022 was $2.1 billion, an increase of 7.0% compared to the prior year, as a result of strong growth in the solar market combined with steady performance in wind.

Specialty Civil backlog at March 31, 2021 was $861.2 million, up 18.4% compared last year due in large part to favorable market trends in environmental.

The Company expects to realize approximately $2.1 billion of its estimated backlog during the next twelve months, an increase of $233 million from the year-ago period.


IEA has provided the following updated financial guidance for the full-year 2022. Full-year guidance accounts for normal factors that may impact our business, including but not limited to weather, permitting delays and project timing, supply chain disruptions, labor constraints, and inflationary factors. All guidance is current as of May 9, 2022 and is subject to change.

Total revenue of between $2.3 billion and $2.5 billion
Total Adjusted EBITDA of between $140 million and $150 million

Non-U.S. GAAP Financial Measures

We define EBITDA as net income (loss), determined in accordance with GAAP, for the period presented, before depreciation and amortization, interest expense and provision (benefit) for income taxes. We define Adjusted EBITDA as EBITDA plus restructuring expenses, acquisition or disposition related expenses, non-cash stock compensation expense, and certain other non-cash charges, unusual, non-operating or non-recurring items and other items that we believe are not representative of our core business or future operating performance.

Adjusted EBITDA is a supplemental non-GAAP financial measure and, when considered along with other performance measures, is a useful measure as it reflects certain drivers of the business, such as revenue growth and operating costs. We believe Adjusted EBITDA can be useful in providing an understanding of the underlying operating results and trends and an enhanced overall understanding of our financial performance and prospects for the future. While Adjusted EBITDA is not a recognized measure under GAAP, management uses this financial measure to evaluate and forecast business performance. Adjusted EBITDA is not intended to be a measure of liquidity or cash flows from operations or a measure comparable to net income as it does not consider certain requirements, such as capital expenditures and depreciation, principal and interest payments, and tax payments. Adjusted EBITDA is not a presentation made in accordance with GAAP, and our use of the term Adjusted EBITDA may vary from the use of similarly-titled measures by others in our industry due to the potential inconsistencies in the method of calculation and differences due to items subject to interpretation.

The presentation of non-GAAP financial information should not be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP.

LTM Revenue from renewables totals over $1.5 billion. Renewables Cost Less than Traditional Power Sources Renewables are the lowest cost form of new generation without incentives. The Levelized Cost of Energy from Wind and Solar is up to 40%-60% lower than the lowest conventional form of power.(1) Renewables are the Preferred Choice of Developers Approximately 90% of all new electrical generation capacity added in the U.S. in 2021 was wind, solar, and other renewable sources.(2) Legislation Provides Upside to Current Forecasts Analysis of the impact from potential legislation shows massive upside. Over the next decade utility-scale solar would see an uplift of 86% from current forecasts with an ITC extension.(2) New Wind Services Business Gaining Traction Expanding addressable market to include maintenance with new Wind Services business Environmental Work Strong Area For Growth Growing coal ash remediation business highlighted by increasing Environmental Remediation revenue (up 134% y/y in Q1-2022) KEY INVESTMENT HIGHLIGHTS EXCITING OPPORTUNITY IN ENERGY TRANSFORMATION (1) Lazard - Levelized Cost of Energy Analysis Version 15.0, Oct 2021.
