The best way to simplify is to set your priorities straight.
So in 2014, Aegion established three priorities:

• Our first priority was, is and always will be

to maintain a safe work environment.

• Our second priority was to reshape our portfolio and
footprint to focus on municipal and energy markets
that offered scale and favorable earning profiles.

• Our third priority was to seek technological
differentiation in those markets through
innovation and new product development.

With those priorities to guide us, our simplification process
began. Since then, we have shed businesses totaling more
than $300 million in 2014 revenues and introduced new
operating models in others. By rebalancing our portfolio
and reducing our complexity, we are left with stronger
businesses that serve sustainable markets with best-in-class
safety performance and increasingly differentiated solutions.

Our work to BE BETTER continues. Entering 2019,
Aegion is SIMPLY STRONGER.

DEAR FELLOW STOCKHOLDERS,

Aegion is focused on the rehabilitation, monitoring and
maintenance of pipeline infrastructure, primarily in North
America. We continue to develop technologies that protect
communities by making pipeline infrastructure stronger,
safer and more reliable.

As we wind down our restructuring efforts to simplify Aegion,
I am excited about leveraging the scale and market position
of our key businesses and delivering more value through our
renewed focus on technical differentiation. We are entering
2019 with the people, solutions and capital to serve our core
municipal and energy markets and earn the returns our
stockholders expect.

2018 SAFETY RESULTS

Aegion again demonstrated best-in-class safety results
companywide in 2018, with total Recordable and Lost Time
Incident Rates continuing to rank in our industries’ top safety
tiers. We believe ZERO INCIDENTS ARE POSSIBLE, and our
Energy Services and Corrosion Protection segments are
proving it. Energy Services, for example, has not experienced
a lost time accident in the last four years and Corrosion
Protection reported fewer injuries in 2018 than ever before.
As we continue our safety journey toward ZERO INCIDENTS,
we are focused on the Infrastructure Solutions segment
attaining a safety record consistent with the excellent
performance across the rest of Aegion.

Maintaining a safe work environment remains our first and
highest priority, and we are committed to providing the best
available safety equipment and training to drive safety
awareness and performance companywide.

THE AEGION SIMPLIFICATION PLAN

2018 OPERATING RESULTS

Aegion delivered 17 percent growth in adjusted earnings per
share in 2018, despite a slight decline in consolidated revenues
compared to 2017. When excluding businesses that were exited
or that we’ve recently announced plans to exit, revenues grew
by 7 percent, reflecting the strength of our key markets. While
more than 80 percent of Aegion’s 2018 revenues were generated
in North America, we also benefited from strong operations
in southeast Asia and the Middle East. In addition, approximately
85 percent of our revenues in 2018 were generated from work
on existing infrastructure, rather than being dependent
on funding for new construction.

Strong project execution on an offshore coating project in the
Middle East and significant top- and bottom-line growth from
our Energy Services segment positively contributed to our
2018 earnings growth. Our Infrastructure Solutions segment
delivered strong contributions, aided by record growth for our
Fusible PVC® pipe offerings and the successful restructuring
of our Fyfe North American operations, though results were
negatively impacted by temporary challenges in our North
American sewer rehabilitation business. Additionally,
we saw a slower than expected recovery in our cathodic
protection business.

Continued strong cash flow generation allowed us to invest
in the maintenance and growth capital required to sustain
and grow the businesses, pay down bank debt, fund the 2017
restructuring program, close two small acquisitions and return
$25 million to stockholders through our stock repurchase
program. This program has allowed us to repurchase nearly
7 million shares and return more than $140 million to Aegion’s
stockholders through open market share repurchases over
the last five years.

Our INFRASTRUCTURE SOLUTIONS segment is a market
leader in the rehabilitation of municipal and industrial pipelines
in North America and select markets throughout the world.
As a world leader in cured-in-place pipe (CIPP), Aegion continues
to invest in technologies to advance our CIPP offering in both
gravity and pressure pipe applications.

We recently introduced the application of ultraviolet (UV)
light technology to cure our felt CIPP tubes for gravity sewer
rehabilitation. This technology reduces the environmental
and equipment footprint required for our curing process,
minimizing disruption to the community.

Effectively sealing household service connections is the
greatest need in the pressure pipe rehabilitation market.
We are now field testing a robotic system that reinstates
these connections with a mechanical seal.

Infrastructure Solutions, which is focused on the municipal
pipeline rehabilitation market, Aegion’s single largest market,
represented approximately 45 percent of the Company’s
consolidated revenues and nearly 64 percent of adjusted
operating income in 2018.

MUNICIPAL PIPELINE REHABILITATION

Revenues for our North American rehabilitation business
were on par with the record results achieved in 2017. Difficult
weather conditions during the first quarter, challenging
project performance in the Midwest and a tight labor market,
which impacted the productivity of crews as we entered new
geographic areas, led to a 4 percent decline in adjusted operating
income for the Infrastructure Solutions segment. However, our
strong backlog and more experienced crews going into 2019
create expectations for better results moving forward.

Our Fyfe North American business delivered lower revenues
in 2018 as expected, after exiting the structural strengthening
contracting business in 2017, but with a significantly more
profitable operating model. By focusing our efforts on higher
value-added engineering support, third-party product sales
and the development of a network of certified applicators
to install our products in structural strengthening applications,
we were able to reduce risk and generate the highest level
of profitability since 2015.

We continued to shift away from CIPP contracting in small
markets outside of North America by transitioning some
of our international CIPP businesses to operating models
that minimize risk. Our Denmark CIPP operation was sold
to a local Scandinavian contractor with multi-year material

supply and technology services agreements. Plans are in place
to close our CIPP business in England and Wales as well as
to sell our CIPP business in Australia through a transaction
that includes multi-year material supply and technology
services agreements with the new owner to source CIPP
products and technology from Aegion. The move outside
of North America from contracting to providing material
and technology sales is not universal. Our CIPP contracting
operations in the Netherlands, Spain, Northern Ireland
and Scotland are expected to be profitable in 2019.

Our Fusible PVC® product lines delivered record results in 2018,
with revenues growing significantly year over year. This success
led to overall pressure pipe bookings increasing by more than 20
percent compared to 2017, aided by the continued development
of our sales force. While we have established a premier portfolio
of pressure pipe rehabilitation products, we are making internal
investments in new technology to improve their installation
and application.

Our CORROSION PROTECTION segment offers technologies
and services that protect and monitor oil & gas pipelines
from the effects of corrosion in North America, the Middle
East and elsewhere around the world. Our solutions include
best-in-class cathodic protection systems to monitor exterior
pipeline corrosion as well as pipeline inspections, interior pipe
linings, interior and exterior pipe weld coatings and insulation.

Our cathodic protection system is based on advanced data
collection units and an asset integrity management database
that interact to provide our customers with digital exterior
corrosion information on pipelines quickly, accurately and in
easy-to-use formats. After several years of internal development,
the data collection units and the asset integrity management
system are now in the early stage of commercialization.

In 2018, Corrosion Protection represented approximately
30 percent of the Company’s consolidated revenues and
nearly 24 percent of its adjusted operating income.

OIL & GAS PIPELINE PROTECTION

The oil & gas infrastructure market continued its recovery
in 2018, trending toward more stable activity levels in most
parts of the world.

Results for the Corrosion Protection segment declined
in 2018 due to significantly lower revenues from a deepwater
project substantially completed in 2017 — the largest project
in the Company’s history. However, a series of offshore coating

2018 AEGION ANNUAL REPORT

RESULTS MATTER.

Aegion is now operating in key markets with the
scale to leverage technology and operating expenses
to create value for our customers and stockholders.
Our strategic focus as we enter 2019 is to combine
operational excellence with technical innovation while
focusing on safety and people.

We will leverage our scale and market position
to deliver more value to our customers.

projects in the Middle East helped offset some of this impact
and contributed significantly to results. We are pleased with
our Middle East team’s exceptionally strong execution and
top-tier safety performance throughout 2018. In particular,
our largest project in 2018 required our team to robotically coat
the interior of 20,000 welds in a complex offshore environment.
Most of the work was executed in 2018, with the remainder to
be completed by the end of the first quarter of 2019. The project’s
success provides good momentum for similar specialty service
projects in the region, where the opportunity pipeline for 2020
and 2021 is robust.

Our United States cathodic protection business benefited
from a 500 basis point improvement in project gross margins
on flat sales, due to improved execution and cost containment.
Field testing of our digital data collection and asset integrity
management database began in 2018 and will continue in 2019
as we start to commercialize these systems. We expect continued
improvement in 2019 from our cathodic protection business
on stronger revenues, boosted by year-end backlog growth
of 16 percent over 2017.

Our pipe linings business grew in the United States, Canada
and the Middle East in 2018, leading to the highest backlog
position in the last four years. We are entering 2019 following
a successful sales year after customer delays in 2018 impacted
the profitability of the business.

We also finalized the sale of The Bayou Companies in August
2018, removing a business with uneven sales and earnings
from our portfolio.

Our ENERGY SERVICES segment is a major provider
of day-to-day maintenance services to refinery customers,
serving as the lead outsourced provider at 14 of the 17
refineries on the United States West Coast.

In addition to critical maintenance services, we perform
turnaround support services, safety services and small capital
construction activities. We believe expanding into scaffolding
services and specialty turnaround services provides an
opportunity to continue to grow our existing customer base.

In 2018, Energy Services represented approximately 25 percent
of the Company’s consolidated revenues and nearly 13 percent
of its adjusted operating income.

DOWNSTREAM REFINERY MAINTENANCE

Our Energy Services segment delivered strong results in 2018,
growing revenues nearly 16 percent and increasing both operating
income and market share. The segment’s success is partially
attributable to the successful transition of all its California
refinery maintenance contracts to our building trade subsidiary
and securing new long-term contracts at several additional
refineries. Energy Services further bolstered its performance
with a $20 million, or more than 70 percent, increase in small
capital construction project revenues and the successful
expansion of our safety services business.

We anticipate increased activity for our specialty turnaround
services, scaffolding services and small capital, time-and-
material construction businesses in 2019. Our 2018 acquisition
of a small turnaround specialty services company provides
us with the management team and access to crews with
the capabilities and skill sets needed for this work.

RESTRUCTURING

Aegion made significant progress in 2018 on our path to
simplification and stable earnings growth. We are now nearing
the end of a process begun in 2014 to position our operations
in markets with favorable scale and earnings profiles, while
exiting or repositioning in markets where growth opportunities
are limited, uneven or better served by a different business
model. We also simplified our overhead and legal entity
structure to align with our new simpler organization.

Aegion will have shed more than 50 percent of its operating
units by the end of 2019 as compared to 2014. Our revenue
growth over the same time frame is expected to be largely
flat, despite exiting businesses that generated approximately
$300 million of revenues in 2014. The exited businesses either
weren’t profitable, added undue risk to Aegion’s ability to provide
stable earnings or did not have the scale to develop and leverage
technology effectively. Through this restructuring, we have also
significantly reduced our upstream oil & gas market exposure
from nearly 20 percent of revenues in 2014 to less than 5 percent
today, and we are well positioned in the more stable midstream
and downstream markets, along with our core municipal water
and wastewater markets.

We are also focused on further reducing operating expenses
to match our more simplified legal entity and overhead
structure. This will require an aggressive focus to control
spending, and we have multiple initiatives underway in 2019
to help achieve this goal.

2018 AEGION ANNUAL REPORT

2019 STRATEGIC FOCUS

LOOKING AHEAD: SIMPLY STRONGER

Our cash position remains strong entering 2019. Cash flow
from operating activities in 2018 was nearly $40 million, and
approximately 100 percent of adjusted net income. This is
in line with our financial targets, despite more than $15 million
in cash restructuring costs. Our balance sheet is in good
shape, with good liquidity and debt at manageable levels.

We expect continued strong cash generation to fund
investments in the maintenance capital required for our
businesses, in R&D and in strategic technology acquisitions.
We will also continue to return cash to stockholders through
our share repurchase programs.

We are targeting modest financial improvement in 2019,
driven by underlying growth in all of our core businesses
that is expected to offset the loss of large project contributions
we have enjoyed in recent years.

Perhaps most significantly, we expect to begin realizing the
benefits of the simplification process we have undertaken.
Shedding businesses and exiting markets are painful. But in
doing so, we have reduced the complexity of our Company and
sharpened our focus on businesses and markets with the scale
to provide stable earnings to our stockholders. This has made
us SIMPLY STRONGER. I have confidence in our plan for moving
forward and the people who will be executing it. I look forward
to sharing Aegion’s progress in our next report.

Thank you for your support.

Charles R. Gordon
President and Chief Executive Officer

With our restructuring efforts largely behind us, we feel
confident Aegion is now operating in key markets with the scale
to leverage technology and operating expenses to create value
for our customers and stockholders. Our strategic focus as
we enter 2019 is to continue to improve the Aegion organization
while combining operational excellence with technical innovation
in the following areas:

Innovation – Innovation drives our ability to SOLVE PROBLEMS
in all facets of our business. In 2019, our Infrastructure Solutions
segment will place particular focus on testing and commercialization
of a new robotic process for reinstating service connections after
installing CIPP in potable water mains at a lower installed cost
and with greater reliability than currently available methods.
We will also continue to expand the application of ultraviolet
technology to cure our CIPP tubes. This approach has the
potential to be more economical, requires a smaller equipment
package than current curing methods and offers the advantage
of significantly reducing the environmental footprint from the CIPP
curing process. Our Corrosion Protection segment continues the
buildout of its asset management platform with an advanced data
collection system to support a range of field applications. It is also
advancing the robotic tools and systems it uses to inspect and
coat internal pipeline welds.

People – Our success is based on Aegion’s ability to continue
to attract, develop and retain talent across the organization.
Millennials are now the largest generation in the United States
workforce and the most racially and ethnically diverse generation
in American history. With the growing retirement of baby
boomers, Millennials will also account for half of the United
States workforce within the next two years.

Creating a diverse and inclusive workforce, beginning with our
senior management team, that reflects this generational shift
is critical to our ability to BE BETTER in the future. We are
working to attract, develop and retain talent at all levels in the
organization so we will have leaders prepared to step in when
needed. A portion of this process includes creating a culture that
embraces diversity and inclusion and makes us more intentional
about recruitment, talent development and employee retention.

Operational Excellence – We remain committed to increasing
our project management discipline and improving operational
execution throughout our Company. Our application of The
Aegion Way, our lean-based continuous improvement process,
continues to yield results. Nine kaizen events held in 2018 led to
improvements to our customer survey process, health, safety and
environmental audit tool and our DOT vehicle inspection process.

SIMPLY STRONGER 5

Innovation drives our
ability to BE BETTER.

R&D and engineering push forward

A robotic breakthrough for water line reinstatement

Advanced data collection for pipeline inspection

Field trials are expected to begin by mid-2019 on a new
robotic method of reinstating service connections on water
and other pressure pipelines that have been rehabilitated
using cured-in-place pipe (CIPP) technology.

This new breakthrough technology addresses a major
issue that currently constrains CIPP use on pressure
pipelines. First, our robot – complete with a mechanical
cutting tool – is small enough to maneuver through even
small 6-inch diameter lines, first plugging and later
reinstating leak-free service connections.

Provisional patent applications have been filed on the technology,
including fittings, robotics and control systems. Developed at
our R&D center in Chesterfield, Missouri, it is also designed
to have a lower installed cost than currently available methods.

Chairman’s Award for Innovation: A greener CIPP liner

Municipalities seeking a greener, less expensive CIPP
alternative will soon have one, thanks to a new hybrid felt/glass
UV-cured liner system developed by a three-person team at
our Insituform subsidiary.

Manufacturing Engineer Charles Free, Wetout Engineering
Manager Jim Rothe and R&D Technical Manager Abu Abraham
worked with our primary felt fiber supplier to develop iPlus
Infusion® UV, a new hybrid felt that is easier to cure using UV
light than today’s glass-based UV alternatives.

This innovation allows us to expand the range of applications
for UV-cured liners, while reducing our environmental footprint.
iPlus Infusion® UV was submitted for NSF/ANSI 61 certification
in fall 2018. If approved, it gives us the industry’s first all-in-one
gravity sewer, pressure and potable water UV-cured lining system.

UV-cured liners are expected to be the fastest-growing segment
of the CIPP market over the next five years.1 Winner of Aegion’s
2018 Chairman’s Award for Innovation, iPlus Infusion® UV will
give us an advantage at the bid table, while delivering the value
and safety municipal customers seek.

Our Asset Integrity Management (AIM) platform will deliver more
value to our customers in 2019 with the commercialization
of our new advanced data collection system.

Currently, users go into the field to collect pipe inspection and
survey data, which is then digitized and stored in our central
Asset Integrity Portal, where customers can access their data
on demand. Our engineers are enhancing this system with
applications to transform this data into actionable information
that aids analysis and problem-solving.

Our advanced data collection system is an add-on service
that automates the data collection and transfer process.
In addition to streamlining our customers’ data collection efforts,
this new subscription service creates market stickiness and
supports our efforts to create full life-cycle pipeline integrity
programs, including corrosion prediction, risk modeling and
trend analyses. Currently designed to collect data regarding
pipe system performance, the data system has future
applications in collecting weather and other field data,
all of which can be managed in our scalable AIM platform.

Eliminating paper audits The Aegion Way

Using The Aegion Way, our continuous improvement
process, we developed a new online health, safety and
environmental tool that improves our ability to audit our
jobsites. The tool was developed by our safety personnel
during one of nine 2018 kaizen events.

Safety staff representing all of our businesses gathered
at the event to create an audit checklist and pass/fail criteria
that address safety and environmental issues. Within a month,
we had the new tool automated and by year-end had completely
eliminated paper audits. Results are now tracked in a database,
making it easy for our operations leadership to track corrective
actions and identify areas needing improvement. Through
this and other efforts to improve safety, we believe
ZERO INCIDENTS ARE POSSIBLE.

3. Advanced data collection system

Our people are the
foundation of our success.

IT’S ALL IN A WORKDAY

Following a 10-month design period, we launched
Workday, our new human capital management platform,
on January 1, 2019. Workday enables us to track and
manage everything from succession planning and
individual employee performance records to employee
goals, career profiles and compensation changes
on a single online portal.

To support career growth, employees will be encouraged
to complete talent profiles and upload resume information
detailing their skill sets, work experience, certifications
and volunteer activity. Managers can mine this data to
identify emerging talent and match internal candidates
with new job opportunities.

Planning for the next generation

The baby boomer generation’s influence is waning.
By 2030, Millennials and post-millennial Generation Z will
make up nearly 75 percent of the workforce. We became more
intentional in 2018 in developing a new generation of leaders
who reflect the diverse and inclusive workforce they will lead
and who are passionate about the success of their fellow
employees and our customers. This increased focus will help
ensure the long-term sustainable success of our Company.

Our efforts included:

Leadership training – Our Talent Management office
now offers 10 leadership courses on topics ranging from
coaching up to sustaining a respectful workplace. We are
employing a collection of webinars and live podcasts
to engage leaders, solicit participation and deliver
real-time education.

Performance management – We have transitioned
from an annual rating-based review system to everyday
performance management designed to build rapport,
set expectations, engage and develop a new generation
of employees.

Career development – To ensure that we have leaders prepared
to step in when needed, we are creating development plans,
career ladders and emerging talent programs across
the organization.

DO WHAT’S RIGHT.

Our culture encourages and rewards employees who
work together in their decision-making, actions and
relationships. We intentionally create a culture of
inclusion through acquiring and retaining a diverse and
talented workforce. The varied strengths, experiences
and backgrounds of our people help us be stronger
and maintain leadership in our markets.

2018 AEGION ANNUAL REPORT

Our business model
is simply stronger.

Transforming our portfolio footprint

By the end of 2019, Aegion will have less than half the
number of operating units it had five years earlier. Our
revenue from 2014 to 2018 has been largely flat, despite
shedding approximately $300 million of revenues from
upstream operations and exiting several countries.

Through this restructuring, we have reduced our upstream
oil & gas market exposure from nearly 20 percent in 2014,
to less than 5 percent today, and we are well positioned
in more stable midstream and downstream markets, along
with our core municipal water and wastewater markets.

CAPITAL ALLOCATION STRATEGY

Our capital allocation strategy is built around our pursuit
of sustainable organic growth and our aim to increase
stockholder value.

Our four spending priorities for 2019 are:

Debt repayment – Our goal is to maintain a debt-to-EBITDA
ratio of less than 3:1.

Invest in current businesses – Capital spending will be
channeled to productivity-enhancing upgrades, technology
advancement and other efforts that support organic growth.

Share repurchases – We are authorized to repurchase up to
$32 million of our common stock in 2019. Actual purchases
will be dependent on share price levels throughout the year.

M&A opportunities – We will take a disciplined approach
to pursuing acquisitions that add new technologies or
services to our portfolio or support our expansion into
new geographic areas.

Criteria that shaped our portfolio and footprint:

EARNINGS STABILITY

MARKET RISK

OPERATIONAL RISK

We look at the potential for steady
earnings growth. Our intent is to improve
predictability by avoiding businesses that
produce uneven revenues, which can lead
to uneven earnings.

Volatility led us to reduce our exposure
in upstream oil & gas markets, as well
as to exit Tyfo® system contract applications
unrelated to pipe in North America. To minimize
risk, we are focusing primarily on markets tied to
existing infrastructure, reducing our dependence
on new construction and related stimulus.

We are transitioning some businesses
to operating models that minimize
operational risk. To reduce our construction
exposure in North America, we converted
Fyfe to a third-party certified applicator
model. Our Corrpro business now focuses
on engineering services related to cathodic
protection system design, maintenance
testing and asset integrity management.

OPERATING LEVERAGE

CASH FLOW

We seek to operate in countries and markets
where we can benefit from scale. We exited
or are in the process of exiting several small
international markets because they cannot
support their overhead costs.

The ability to generate adequate cash
flow is another consideration and led to
changes in Brazil, Argentina, Mexico and some
Middle East markets.

RETURN ON INVESTED CAPITAL

The final consideration is our ability
to consistently deliver appropriate
profitability and returns.

2018 AEGION ANNUAL REPORT

WE SOLVE PROBLEMS.

We invested substantial resources in transforming our
portfolio and footprint over the past four years. We now
operate in end markets with favorable scale and earnings
profiles, having exited or repositioned our businesses
in markets where growth opportunities are limited,
uneven or better served by another model. With these
efforts nearing completion, we are turning our attention
to technological differentiation and expense control.

SIMPLY STRONGER

By rebalancing our portfolio and reducing our complexity, Aegion is
SIMPLY STRONGER today than when we began our simplification
process in 2014. From our disciplined approach to sales and project
risk management, to our safety, operational excellence and capital

2018 Results

INFRASTRUCTURE SOLUTIONS

CORROSION PROTECTION

ENERGY SERVICES

The Infrastructure Solutions segment had
lower revenues and operating margins
in 2018, driven by our North American
rehabilitation business’s first year-over-year
profit decline in seven years.

Restructuring our Fyfe North American business
resulted in lower revenues, but a $7.5 million
year-over-year increase in operating income.
A 20 percent increase in pressure pipe sales
fueled record performance for our Fusible
PVC® product line.

Revenues in the Corrosion Protection
segment declined 14 percent in 2018
due to the absence in 2018 of significant
revenues from the large deepwater project,
substantially completed in 2017, partially
offset by the success of a series of offshore
coating projects in the Middle East. While
results in the remainder of the segment were
flat, our cathodic protection business in the
United States benefited from a 500 basis point
gross margin improvement due to improved
execution and cost containment.

Energy Services segment revenues
grew nearly 16 percent in 2018 on
growth across all revenue streams,
while also increasing operating income
and market share.

In addition to transitioning all embedded
California refinery maintenance business
to the Company’s building trades subsidiary
successfully, the segment extended and
added multiple contracts and a turnaround
specialty company to its portfolio.

Outlook

INFRASTRUCTURE SOLUTIONS

CORROSION PROTECTION

ENERGY SERVICES

Field testing of our digital data collection and
asset integrity management systems will
continue in 2019 as we begin to commercialize
these systems. Continued improvement
is expected in our cathodic protection and
pipe linings businesses, boosted by stronger
revenues and backlog growth. The success
of several recent offshore field joint coating
projects in the Middle East provides good
momentum for the robust opportunity
pipeline for 2020 and 2021.

A key service provider to West Coast
refineries, Energy Service is positioned
to expand revenues and margins in 2019
through increased activity in its specialty
turnaround services, scaffolding services
and small-capital, time-and-material
construction businesses. The segment
is expected to deliver low-single-digit
revenue growth and improve gross
margins by 50 to 100 basis points in 2019.

Strong backlog and the addition of new
crews position the segment in 2019 for
revenue growth in the 6 - 8 percent
range (excluding the impact of exited
or to-be-exited businesses) and expectations
for improved results.

Our new robotic service reinstatement
and UV felt products are expected to expand
our overall market presence and improve
our position for both third-party product
sales and contract work. A positive tailwind is
expected to benefit 2019 sales and initiatives.

Overview

Aegion combines innovative technologies with market leading expertise to maintain, rehabilitate and strengthen pipelines
and other infrastructure around the world. Since 1971, we have played a pioneering role in finding transformational solutions
to rehabilitate aging infrastructure, primarily pipelines in the wastewater, water, energy, mining and refining industries. We
also maintain the efficient operation of refineries and other industrial facilities and provide innovative solutions for the
strengthening and increased longevity of buildings, bridges and other structures. We are committed to Stronger. Safer.
Infrastructure®. We believe the depth and breadth of our products and services make us a leading provider for the world’s
infrastructure rehabilitation and protection needs.

Our Company premise is to use technology to extend the structural design life and maintain, if not improve, the

performance of infrastructure, mostly pipelines and piping systems. We have proved this expertise can be applied in a variety
of markets to protect pipelines in oil, gas, nuclear, power, utility, mining, wastewater and water applications and can be
extended to the rehabilitation and maintenance of commercial structures and the provision of professional services in energy-
related industries. Many types of infrastructure must be protected from the corrosive and abrasive materials that pass through
or near them. Our expertise in non-disruptive corrosion engineering and abrasion protection is wide-ranging. We have a long
history of product development and intellectual property management. We manufacture many of the engineered solutions we
offer to customers as well as the specialized equipment required to install them. Finally, decades of experience give us an
advantage in understanding municipal, utility, energy, mining, industrial and commercial customers. Strong customer
relationships and brand recognition allow us to support the expansion of existing and innovative technologies in our core end
markets.

We originally incorporated in Delaware in 1980 to act as the exclusive United States licensee of the Insituform® cured-in-
place pipe (“CIPP”) process, which Insituform’s founder invented in 1971. The Insituform® CIPP process served as the first
trenchless technology for rehabilitating wastewater pipelines and has enabled municipalities and private industry to avoid the
extraordinary expense and extreme disruption that can result from conventional “dig-and-replace” methods. We have
maintained our leadership position in the CIPP market from manufacturing to technological innovations and market share for
over 45 years.

We embarked on a diversification strategy in 2009 to expand not only our geographic reach but also our product and
service portfolio into the oil and gas markets. Through a series of strategic initiatives and key acquisitions, we now possess a
broad portfolio of cost-effective solutions for rehabilitating and maintaining aging or deteriorating infrastructure, protecting
new infrastructure from corrosion and other threats, and providing integrated professional services in engineering, procurement,
construction, maintenance and turnaround services for oil and natural gas companies, primarily in the midstream and

downstream markets. Today, our long-term strategy is to invest in our core end markets for organic growth and acquire
innovative technologies to enhance our competitive position.

Our Segments

We have three operating segments, which are also our reportable segments: Infrastructure Solutions, Corrosion Protection

and Energy Services. Our operating segments correspond to our management organizational structure. Each operating
segment has leadership that reports to our chief executive officer, who is also the chief operating decision manager (“CODM”).
The operating results and financial information reported by each of the segments are evaluated separately, reviewed regularly
and used by the CODM to evaluate segment performance, allocate resources and determine management incentive
compensation. See Note 14 to the consolidated financial statements contained in this Report for further discussion regarding
our segments.

Infrastructure Solutions – The majority of our work is performed in the municipal water and wastewater

pipeline sector and, while the pace of growth is primarily driven by government funding and spending, overall demand
due to required infrastructure improvements in our core markets should result in a long-term stable growth opportunity
for our market leading products, Insituform® CIPP, the Tyfo® system and Fusible PVC® pipe.

Corrosion Protection – Corrosion Protection is positioned to capture the benefits of continued oil and natural gas

pipeline infrastructure developments across North America and internationally, as producers and midstream pipeline
companies transport their product from onshore and offshore oil and gas fields to regional demand centers. The
segment has a broad portfolio of technologies, products and services to protect, maintain, rehabilitate, assess and
monitor pipelines from the effects of corrosion, including cathodic protection, interior pipe linings, interior and
exterior pipe coatings and inspection and repair capabilities, as well as an increasing offering of data management
capabilities related to these services. We provide solutions to customers to enhance the safety, environmental integrity,
reliability and compliance of their pipelines in the global transmission and distribution network, especially in the oil
and gas markets.

Energy Services – We offer a unique value proposition based on our world-class safety and labor productivity
programs, which allow us to provide cost-effective construction, maintenance, turnaround and specialty services at
customers’ refineries as well as chemical and other industrial facilities. We understand the demands and the level of
critical planning required to ensure a successful turnaround or shutdown and offer a full range of services as part of
our facility maintenance solutions, while maintaining a reputation for being safe, professional and providing
predictable value.

Our Long-Term Strategy

We are committed to being a valued partner to our customers, with a constant focus on expanding those relationships by

solving complex infrastructure problems, enhancing our capabilities and improving execution while also developing or
acquiring innovative technologies and comprehensive services. We are pursuing three key strategic initiatives:

Municipal Pipeline Rehabilitation – The fundamental driver in the global municipal pipeline rehabilitation
market is the growing gap between the need and current spend. While we do not expect the spending gap to close any
time soon, the increasing need for pipeline rehabilitation supports a long-term sustainable market for the technologies
and services offered by our Infrastructure Solutions segment. We are committed to maintaining our market leadership
position in the rehabilitation of wastewater pipelines in North America using our CIPP technology, the largest
contributor to Aegion’s consolidated revenues. We have a diverse portfolio of trenchless technologies to rehabilitate
aging and damaged municipal pipelines. The focus today is growing our presence in the rehabilitation of pressure
pipelines through both internal development and acquisitions. Our pressure pipe portfolio includes Fusible PVC®,
InsituMain® CIPP, Tyfo® fiber-reinforce polymer (“FRP”) and Tite Liner® high-density polyethylene (“HDPE”)
systems. Our international strategy is to use a blend of third-party product sales as well as CIPP and FRP contract
installation operations in select markets. A key to the success of this strategy is a continuing focus on improving
productivity to reduce costs and increase efficiencies across the entire value chain from engineering, manufacturing
and installation of our technology-based solutions.

Pipeline Integrity and Corrosion Management – There are over one million miles of regulated pipelines in

North America, which remain the safest and most cost-effective mode of oil and gas transmission. Within our
Corrosion Protection segment, the design and installation of cathodic protection systems to help prevent pipeline
corrosion have historically represented a large portion of the revenues and profits for the segment. We also provide
inspection services to monitor these systems and detect early signs of corrosion. In 2017, we launched a new asset
integrity management program designed to increase the efficiency and accuracy of the pipeline corrosion assessment
data we collect as well as upgrade how we share this valuable information with customers. Through this program, we

seek to improve customer regulatory compliance and add new services in the areas of data gathering and validation,
advanced analytics and predictive maintenance.

Downstream Oil Refining and Industrial Facility Maintenance – We have long-term relationships with oil

refinery and industrial customers on the United States West Coast through our Energy Services segment. Our
objective is to leverage those relationships to expand the services we provide in mechanical maintenance, electrical
and instrumentation services, small capital construction, shutdown and turnaround maintenance activity and specialty
services. We also continue to promote our safety and scaffolding services. There are opportunities in other industries
on the West Coast such as oil and oil product terminals, chemicals, industrial gas and power to leverage our experience
in maintenance and construction services. In addition, we are looking to expand our turnaround and specialty services
beyond the West Coast.

Our Products and Services

Today our diverse portfolio of full service solutions includes:

the largest independent consulting corrosion engineering organizations in the world. We also provide project management,
training, research, testing and design, consultation and installation services to the following markets: pipeline, refinery, above
and underground storage tanks, water/wastewater structures, concrete infrastructure and offshore and marine structures. We
also offer a full line of superior quality corrosion control and cathodic protection materials, which are NSF/ANSI 61 classified
for drinking water system components. More recently, we have enhanced our pipeline inspection services through the internal
development of an asset integrity management program, which is designed to digitize the critical pipeline data we gather and
efficiently transmit, store and display the results to our customers.

Pipe Coatings for Corrosion and Thermal Control and Prevention – We provide products and services to protect pipes
from corrosion primarily for the oil and gas industries. We accomplish this through external and internal pipe coatings utilizing
fusion bonded epoxy (“FBE”) and field joint coating for corrosion protection of fittings, valves and other primary sources for
metal corrosion. Additionally, we provide custom coating services on pipe bends, fittings, fabricated spools, valves and short
runs of straight pipe for oil, gas and potable water services, as well as onshore or offshore fabrication and welding services. We
also offer a proprietary robotic pipe coating and inspection technology for internal and external welded pipe field joints.

Thermoplastic Pipe Lining for Corrosion Control, Abrasion Protection and Pipeline Rehabilitation – Our proprietary

Tite Liner® installation system provides chemical, corrosion and abrasion resistance for numerous pipeline applications,
including in the oil and gas, mining and chemical pipeline markets, and has application in the rehabilitation of pressure pipes in
the municipal marketplace. Our system can rehabilitate pipelines for a fraction of the cost and time associated with industrial
pipeline replacement. We offer our lining protection products and services worldwide, with a strategic focus on expanding our
presence in key end markets with sustainable capital spend on oil, gas and mining activities.

Our cathodic protection capabilities and products for lining and coating pipelines are applicable worldwide in the oil, gas

and mining markets, with a focus on North America and the Middle East.

Construction and Maintenance of Oil and Gas Facilities – Through our Energy Services segment, which operates as
Aegion Energy Services, we are a leading integrated service provider of maintenance, construction and turnaround activities for
the downstream oil and gas markets. Focused on serving large refinery customers on the United States West Coast, but with
recent or planned growth in Hawaii, Utah and the United States Rocky Mountain and Upper Midwest regions, Energy Services
offers an industry-leading safety record, a strong reputation for reliability and quality and comprehensive solutions needed for
major refinery maintenance, repairs and retrofits. These core competencies position Energy Services to meet the growing
demand for non-discretionary operating and maintenance expenditures.

Strategic Initiatives and Key Divestitures

Restructuring Activities

2017 Restructuring

On July 28, 2017, our board of directors approved a realignment and restructuring plan (the “2017 Restructuring”). As part
of the 2017 Restructuring, the Company announced plans to: (i) divest the Company’s pipe coating and insulation businesses in
Louisiana, The Bayou Companies, LLC (“Bayou”) and Bayou Wasco Insulation, LLC (“BWI”); (ii) exit all non-pipe related
contractor applications for the Tyfo® system in North America; (iii) right-size the cathodic protection services operation in
Canada and the CIPP businesses in Australia and Denmark; and (iv) reduce corporate and other operating costs.

During 2018, the Company’s board of directors approved additional actions with respect to the 2017 Restructuring, which
included the decisions to: (i) divest the Australia and Denmark CIPP businesses; (ii) take actions to further optimize operations
within North America, including measures to reduce consolidated operating costs; and (iii) divest or otherwise exit multiple
additional international businesses, including: (a) our cathodic protection installation activities in the Middle East, including
Corrpower International Limited, our cathodic protection materials manufacturing and production joint venture in Saudi
Arabia; (b) United Pipeline de Mexico S.A. de C.V., our Tite Liner® joint venture in Mexico; (c) our Tite Liner® businesses in
Brazil and Argentina; (d) Aegion South Africa Proprietary Limited, our Tite Liner® and CIPP joint venture in the Republic of
South Africa; and (e) our CIPP contract installation operations in England.

We divested our Bayou business in August 2018 and our Denmark CIPP business in November 2018. Discussions are

underway with a prospective buyer for the sale of the Australia CIPP business. If discussions are successful, a transaction is
expected to be completed during the first half of 2019. Planned divestitures or exits of the remaining international businesses
noted above are expected to be substantially complete by June 30, 2019.

We expect the 2017 Restructuring to reduce consolidated annual expenses as well as eliminate significant losses over the

last several years from underperforming businesses.

2016 Restructuring

On January 4, 2016, our board of directors approved a restructuring plan (the “2016 Restructuring”) to reduce our exposure

to the upstream oil markets and to reduce consolidated expenses. During 2016, we completed the 2016 Restructuring, which:
(i) reduced/eliminated Energy Services’ upstream operations in California and in the Permian Basin in Texas; (ii) reduced
Corrosion Protection’s upstream exposure by divesting our interest in Bayou Perma-Pipe Canada, Ltd. (“BPPC”), our Canadian
pipe coating joint venture; (iii) right-sized Corrosion Protection to compete more effectively; and (iv) reduced corporate and
other operating costs.

See Notes 1 and 4 to the consolidated financial statements contained in this Report for a detailed discussion regarding

strategic initiatives and restructuring efforts.

Divestitures – Planned and Completed

Through our restructuring efforts discussed above, we have divested, or have made the decision to divest, certain

businesses in our Infrastructure Solutions and Corrosion Protection segments during 2018, 2017 and 2016:

i. On October 30, 2018, we executed a sale agreement for substantially all of the fixed assets and inventory from our
CIPP operations in Denmark. In connection with the sale, we entered into a five-year exclusive tube-supply
agreement whereby the buyers will exclusively purchase our Insituform® CIPP liners. The buyers will also be
entitled to use the Insituform® trade name based on a trademark license granted for the same five-year time period.

ii. On August 31, 2018, we sold substantially all of the assets of Bayou and our ownership interest in Bayou Wasco

Insulation LLC, which collectively had been held for sale as part of the 2017 Restructuring and reflected our desire to
reduce further our exposure in the North American upstream oil and gas markets.

iii. On May 14, 2018, our board of directors approved plans to divest the assets and liabilities of our CIPP operations in
Australia. While restructuring actions in Australia led to year-over-year improvements in operating results in 2018,
an assessment of the long-term fit within Aegion’s portfolio led to the decision to divest the business. A sales process
is under way and management expects that a sale will occur in the first half of 2019.

iv. In February 2016, we sold our fifty-one percent (51%) interest in BPPC to our joint venture partner, Perma-Pipe, Inc.

BPPC served as our pipe coating and insulation operation in Canada. The sale of our interest in BPPC was part of a
broader effort to reduce our exposure in the North American upstream market.

v. During the first quarter of 2019, we entered into discussions with prospective buyers regarding the sale of our

interests in Corrpower International Limited and Aegion South Africa Proprietary Limited. If the discussions are
successful, we expect to close the transactions in the first half of 2019.

See Note 1 to the consolidated financial statements contained in this Report for a detailed discussion regarding strategic

initiatives and divestitures.

Technologies

Infrastructure Solutions

Our Insituform® CIPP process (including Insitupipe® and Insitutube®) for the rehabilitation of wastewater pipelines and
other conduits utilizes a custom-manufactured tube, or liner, made of synthetic fiber. After the tube is saturated (impregnated)
with a thermosetting resin mixture, it is installed in the host pipe by various processes. The resin is then cured, by heat (hot
water or steam) or ultraviolet light, forming a new rigid pipe within a pipe.

Our iPlus® Infusion® pull-in CIPP is a trenchless method for the rehabilitation of small-diameter wastewater pipelines,
whereby a felt liner is continuously impregnated with liquid, thermosetting resin through a proprietary process, after which the
liner is pulled into the host pipe, inflated with air and cured with steam or ultraviolet light.

Our iPlus® Composite CIPP is used for the trenchless rehabilitation of large-diameter wastewater pipelines, where the felt
liner is reinforced with carbon or glass fiber, impregnated with liquid, thermosetting resin, inverted into place and cured with
hot water or steam.

Our InsituMain® CIPP system is a solution for pressure pipes, including water mains and force mains up to 96-inches in
diameter. The system can negotiate bends and is pressure-rated up to 150 psi. The InsituMain® system has also been certified
as complying with NSF/ANSI Standard 61.

Our Insituform® RPP™ process is a trenchless technology used for the rehabilitation of wastewater force mains and
industrial pressure pipelines. The felt tube is reinforced with glass and impregnated with liquid, thermosetting resin, after
which it is inverted with water and cured with hot water to form a structural, jointless pipe within the host pipe.

Our Insituform® PPL® process is a trenchless technology certified to NSF/ANSI Standard 61 used for the rehabilitation of

drinking water and industrial pressure pipelines. A glass-reinforced liner is impregnated with an epoxy or vinyl ester resin,
inverted with water and cured with hot water to form a jointless pipe lining within the host pipe.

Our iPlus® Glass UV system is a CIPP solution for small- to medium-diameter pipes utilizing a glass fiber tube that is
impregnated with a resin sensitive to ultraviolet light. The tube is pulled into place in the host pipe, inflated by air and cured
via an ultraviolet light source.

Sliplining is a method used to push or pull a new pipeline into an old one. With segmented sliplining, short segments of

pipe are joined to form the new pipe. For gravity wastewater rehabilitation, these short segments can often be joined in a
manhole or access structure, eliminating the need for a large pulling pit.

Our iTap® is an internal service line reinstatement process that includes associated fittings, robotics and control systems for

leak free connections in CIPP lined potable water mains.

Our Fusible PVC® technology contains proprietary polyvinyl chloride (“PVC”) formulation that, when combined with its

patented fusion process, results in a monolithic, fully-restrained, gasket-free, leak-free piping system. Fusible PVC® pipe
products include Fusible C-900® and FPVC® pipes. Fusible C-900® pipes comply with the AWWA C900 standard and are
certified to the NSF/ANSI Standard 61.

Our Tyfo® system applies high-strength fiber fabric to strengthen structures, including pipelines, and the connections
between structural components, thereby strengthening, repairing and restoring masonry, concrete, steel and wooden structures.
Beyond general strengthening of pipelines and structures, the Tyfo® system also has application in blast mitigation and seismic
reinforcement.

See “Patents and Proprietary Technologies” below for more information concerning certain of these technologies.

Corrosion Protection

Our Tite Liner® system is a method of lining new and existing pipe with a corrosion and abrasion resistant thermoplastic

pipe.

Our Safetyliner™ product is a grooved thermoplastic liner that is installed in an industrial pipeline using the Tite Liner®
process. The Safetyliner™ liner is normally used in natural gas or CO2 pipelines to allow the release of gas that permeates the
thermoplastic liner. If gas is allowed to build in the annular space under normal operating conditions, the line can be
susceptible to collapse upon sudden changes in operating pressures. The Safetyliner™ liner also has been used in pipelines as a
leak detection system and for dual containment in mine water pipelines.

The fusion bonded epoxy application process utilizes heat to melt a dry powder FBE coating material into liquid form.
The liquid material flows onto the steel pipe and solidifies through a process called cross-linking. Once cooled, this “fusion-
bonded” epoxy cannot return to its original state and forms a corrosion protection barrier on the interior or exterior surface of
the pipe.

Our 3-layer polyethylene coating is an external coating for buried or submerged oil or gas pipelines and offers superior

adhesion, cathodic disbondment resistance and mechanical protection.

Our deepwater coating and insulation capabilities answer the challenge of subsea wet insulation requirements for high-
pressure and high-temperature environments. Applications include subsea equipment and field joints for coating the girth
welds where the pipe coating has been cutback to allow for welding joints of pipe.

Our internal field joint coating technology consists of self-contained robots that travel inside the pipe, find the weld and
then blast clean, vacuum and coat the area. Utilizing various cameras, these field joint coating robots transmit a real-time video
image back to the operator which is then used for control and inspection. The technology allows for the field application of
FBE and plural component liquid materials to the weld area.

Cathodic protection is an electrochemical process that prevents corrosion of new structures and stops corrosion on existing

structures. Metal loss is prevented by the passing of a very small direct current from a cathodic protection electrode (anode),
through the electrolyte (soil, water, concrete, etc.) on to the structure to be protected (cathode). In this process, the anode
corrodes, sacrificing itself to protect the integrity of the cathode. Structures commonly protected by this process include oil and
gas pipelines, offshore platforms, above and underground storage tanks, ships, electric power plants, bridges, parking garages,
transit systems and water and wastewater facilities.

Our CorrFlex® system is a linear anode system installed parallel to pipelines, oftentimes to prevent stress corrosion

cracking that can lead to ruptures on high pressure gas transmission pipelines.

Our CorrSpray® product provides a unique solution for preventing corrosion of steel reinforcements in concrete structures.

Our Corrporwer® DC power supplies include innovative designs, plus remote monitoring and control capabilities.

Our Green Rectifier® system is an ecologically friendly method of cathodic protection using solar panels and a wind

generator to power the cathodic protection process.

Our Grid™ system has set the global standard for preventing releases from external corrosion of at-grade storage tanks

containing oil and petroleum products, thereby ensuring safe operations and protection of the environment.

Our AC interference mitigation solution protects pipeline operators and the public from electrical hazards when pipelines

share space on rights-of-way with overhead electric transmission lines. Beginning with advanced predictive modeling, we then
design mitigation schemes and provide systems to protect people and the pipeline.

Our asset integrity management platform allows for the collection, communication and storage of data in a geospatial
information system-based, centralized, integrated repository that provides us and our customers more timely information and
improved data analytics. Data collection applications include LiveLine™ and CIS View™, data delivery applications include
AssetView™ and FieldLine®, and data analytical tools include ScanLine™, ChargeLine® and BaseLine™.

See “Patents and Proprietary Technologies” below for more information concerning certain of these technologies.

Energy Services

Our DelayTrak® system identifies delays in real time. The data is used to identify and quickly communicate improvement

opportunities and, later, action plans for improvement.

Our TimeTrak™ system tracks how time is spent by crews on a jobsite. The data is used to drive process improvements in

routine maintenance.

Operations

We are organized into three operating segments, which are also our reportable segments: Infrastructure Solutions,

Corrosion Protection and Energy Services. Each segment is regularly reviewed and evaluated separately.

Our operations are generally project oriented. Projects may range in duration from just a few days to several years and can

be performed as one-time contracts or as part of longer-term agreements. These contracts are usually obtained through
competitive bidding or negotiations and require performance at a fixed price or time and materials basis. Our Corrosion
Protection and Energy Services projects are generally performed under contracts with industrial entities. A majority of our
water and wastewater rehabilitation installation projects in our Infrastructure Solutions segment are performed under contracts
with municipal entities. Independent contractors may be utilized to perform portions of the work on any given project that we
provide.

Infrastructure Solutions Operations

Our water and wastewater pipeline rehabilitation activities are conducted principally through installation and other

construction operations performed directly by our subsidiaries.

Our North American Infrastructure Solutions operations, including research and development, engineering, training and
financial support systems, are headquartered in St. Louis, Missouri. Tube manufacturing and processing facilities for North
America are maintained in ten locations, geographically dispersed throughout the United States and Canada to support our
North American contracting operations and through which we sell liners to third parties, domestically and internationally.

We also conduct Insituform® CIPP process rehabilitation operations worldwide through our wholly-owned subsidiaries.
We utilize multifunctional robotic devices developed by a wholly-owned French subsidiary in connection with the inspection
and repair of pipelines. We also maintain a manufacturing facility in Wellingborough, United Kingdom and three processing
facilities in Europe to support our international operations and through which we sell liners to third parties internationally.

We have granted licenses to our trenchless rehabilitation processes to unaffiliated companies in certain geographic regions.

As described under “Ownership Interests in Operating Licensees and Joint Ventures” below, we have also entered into
contractual joint ventures from time to time to capitalize on our trenchless rehabilitation processes. Under these contractual
joint venture relationships, work is bid by the joint venture entity and subcontracted to the joint venture partners or to third
parties. The joint venture partners are primarily responsible for their subcontracted work, but both joint venture partners are
liable to the customer for all of the work. Revenues and associated costs are recorded using percentage-of-completion
accounting for our subcontracted portion of the total contract only.

In addition to wastewater pipeline rehabilitation, we have performed water pipeline rehabilitation operations since 2006

using our pressure pipe product portfolio. We are now able to restore water pipes using our InsituMain® CIPP and the Tite
Liner® and Tyfo® systems.

Our acquisition in February 2016 of Underground Solutions, headquartered in Poway, California, bolstered our capabilities

with respect to water pipeline rehabilitation operations. We are now able to provide additional infrastructure technologies for
water, wastewater and conduit applications, primarily Fusible PVC® pipe, which, when combined with its patented fusion
process, results in a monolithic, fully-restrained, gasket-free, leak-free piping system.

Our infrastructure rehabilitation operations also utilize FRP to rehabilitate and strengthen pipelines throughout the United
States through Fibrwrap Construction Services, headquartered in San Diego, California. We also design and manufacture FRP
composite systems used for rehabilitating buildings, bridges, tunnels, industrial developments and waterfront structures, which
we supply to certified applicators. We service the European FRP markets with respect to product and engineering services
through our wholly-owned subsidiaries in the United Kingdom. We service the Asia-Pacific FRP market, with respect to both
product and engineering services as well as application services, through our wholly-owned subsidiaries in Singapore,
Malaysia, Hong Kong and New Zealand and through our joint ventures in Borneo and Indonesia. Finally, we have granted
licenses to our proprietary FRP products and processes to unaffiliated companies in certain additional geographic regions, as
described under “Licensees” and “Ownership Interests in Operating Licensees and Joint Ventures” below.

Corrosion Protection Operations

Our corrosion protection operations perform maintenance, rehabilitation and corrosion protection services for oil and gas,

industrial and mineral piping systems and structures. We also offer products for gas release and leak detection systems. Our
worldwide corrosion protection operations are headquartered in Houston, Texas and conducted through our various subsidiaries
(Corrpro based in Houston, Texas; United Pipeline Systems based in Durango, Colorado; and Aegion Coating Services, LLC
(“ACS”) based in Tulsa, Oklahoma and Conroe, Texas). Certain of our corrosion protection operations outside of the United
States are conducted through our wholly-owned subsidiaries in the United Kingdom, Chile, Canada, Saudi Arabia and through
our joint venture in Oman.

Our Corrpro business performs fully-integrated corrosion prevention services including: (i) engineering and design; (ii)

product and material sales; (iii) construction and installation; (iv) inspection, surveying, monitoring, data collection and
maintenance; and (v) coatings. United Pipeline Systems performs pipeline rehabilitation and protection services using our
proprietary Tite Liner® process. Our ACS business specializes in the application of internal corrosion coatings services,
provision of external field joint anti-corrosion coating services and the supply of equipment, all for pipeline construction
projects onshore and offshore in locations around the world.

Energy Services Operations

Aegion Energy Services is based in Irvine, California and performs construction, maintenance and turnaround services,
primarily for the downstream oil and gas industry. Aegion Energy Services’ operations are located primarily in California and
Washington, however, our new wholly-owned turnaround specialty company, P2S ServTech, LLC, is headquartered in Texas.
We specialize in offering clients a flexible, single source for all project needs. Clients may choose a single service or multiple
integrated services, from technical consulting to turnkey project delivery, ongoing maintenance and scaffolding services. We
provide project management professionals across various disciplines, including chemical, civil, structural, mechanical,
electrical, instrumentation, project controls, estimating, procurement and safety. AllSafe Services, Inc., a wholly-owned
subsidiary of Aegion Energy Services, provides safety field services.

Sweeping refinery industry changes occurred in California in recent years as a result of the implementation of California

Health and Safety Code section 25536.7 (the “California Refinery Safety Law”). The California Refinery Safety Law
introduced new requirements for refineries and outside contractors at certain facilities in California covered by the law. Over
the past few years, Aegion Energy Services has successfully transitioned all of its clients’ refinery operations covered by the
California Refinery Safety Law to building trade union employees, as required by its clients in order to comply with the
California Refinery Safety Law.

Licensees

We have granted licenses for the Insituform® CIPP process covering exclusive and non-exclusive territories to non-
affiliated licensees that provide pipe repair and rehabilitation services throughout their respective licensed territories. The
licenses generally grant to the licensee the right to utilize our know-how and patent rights (where such rights exist) relating to
the subject process, and to use our copyrights and trademarks. These licenses have an average term of ten years with a right to
renew.

Our CIPP licensees generally are obligated to pay a royalty at a specified rate. Any improvements or modifications a

licensee may make in the subject process during the term of the license agreement generally becomes our property or is
licensed to us. Should a licensee fail to meet its royalty obligations or other material obligations, we may terminate the license
at our discretion. Licensees, upon prior notice to us, may generally terminate the license for certain specified reasons. We may
vary the terms of agreements entered into with new licensees according to prevailing conditions. Income from royalties are
immaterial to our overall consolidated revenues.

Our Fyfe joint ventures in Borneo and Indonesia provide design, product and engineering support to applicators of FRP
systems in Asia-Pacific. Our joint ventures in Asia-Pacific are granted the non-exclusive right to use Fyfe products in their
respective territories. Fyfe Co. also periodically licenses its patented technology to both affiliated and third-party certified
applicators.

With regard to our Underground Solutions business, we have granted licenses to our Fusible PVC® pipe products and
fusion processes internationally covering exclusive and non-exclusive territories to non-affiliated licensees that provide fusible
PVC products and services. The licenses generally grant to the licensee, in exchange for royalties at a specified rate, the right
to utilize our know-how and patent rights (where such rights exist) relating to the subject products and processes, and to use our
copyrights and trademarks. Underground Solutions also licenses domestically its patented technology to third-party extruders
and installers.

Ownership Interests in Operating Licensees and Joint Ventures

We hold controlling interests in Fyfe/Fibrwrap joint ventures in Borneo and Indonesia. Through our wholly-owned
subsidiary, Fyfe Asia Pte. Ltd., we hold (i) a fifty-one percent (51%) equity interest in Fyfe Borneo Sdn Bhd., with the other
forty-nine percent (49%) equity interest held by C. Tech Sdn Bhd; and (ii) a fifty-five percent (55%) equity interest in PT Fyfe

Through our subsidiary Aegion International Holdings Limited, we hold a sixty percent (60%) equity interest in Aegion

South Africa Proprietary Limited located in South Africa, through which we provide pipeline rehabilitation products and
services in East and Southern Africa. The other forty percent (40%) equity interest is held by Robor Proprietary Limited, a
South African manufacturer and supplier of steel pipe. As discussed in “Strategic Initiatives and Key Divestitures” above, we
are currently in the process of exiting this joint venture as part of the 2017 Restructuring.

We have previously entered into teaming and other cooperative arrangements in various geographic regions throughout the

world in order to develop cooperative bids on contracts for our thermoplastic pipeline rehabilitation and cathodic protection
businesses. Typically, the arrangements provide for each participant to complete its respective scope of work, and we are not
required to complete the other participant’s scope of work. We continue to investigate opportunities for expanding our business
through such arrangements.

We previously entered into contractual joint ventures in other geographic regions in order to develop joint bids on contracts

for our wastewater pipeline rehabilitation business. Typically, the joint venture entity holds the contract with the owner and
subcontracts portions of the work to the joint venture partners. As part of the subcontracts, the partners usually provide bonds
to the joint venture. We could be required to complete our joint venture partner’s portion of the contract if the partner were
unable to complete its portion and a bond is not available. We continue to investigate opportunities for expanding our business
through such arrangements.

Product Development

We seek out and develop innovative solutions for pipelines and other infrastructure through a stage-gate process for
management of our research and development initiatives. The process is executed under the direction of our Chief Technical
Officer with a market and business impact evaluation at each gate review. Corporate and business unit resources make up the
specific research and development teams, supplemented, where beneficial, by our technology partners (often major suppliers),
outside consultants and academic institutions. During the years ended December 31, 2018, 2017 and 2016, we spent $5.6
million, $4.2 million and $4.7 million, respectively, on research and development related activities, including engineering.

Customers and Marketing

We offer our products and services to highly diverse markets worldwide. We service municipal, state and federal

governments, as well as corporate customers in numerous industries including pipelines, energy, oil and gas, refinery, mining,
general and industrial construction, infrastructure (buildings, bridges, tunnels, railways, etc.), water and wastewater,

transportation, utilities, maritime and defense. Our products and services are currently utilized and performed in over 80
countries across six continents.

We offer our corrosion protection solutions worldwide to energy, refinery, mining and other customers to protect new and
existing pipelines and other structures. The marketing of wastewater pipeline rehabilitation technologies is focused primarily
on the municipal wastewater markets worldwide. We offer our water rehabilitation products to municipal and commercial
customers. We offer our other infrastructure rehabilitation products worldwide to certain certified third-party installers and
applicators and market our engineering, manufacturing and, in some countries, installation services to municipal, state, federal
and commercial customers. We offer our Energy Services solutions primarily to the oil and gas markets on the West Coast, but
have been actively pursuing opportunities beyond the West Coast. No customer accounted for more than 10% of our
consolidated revenues during the years ended December 31, 2018 or 2016. During the year ended December 31, 2017, we had
one customer that accounted for approximately 12.1% of our consolidated revenues primarily due to a large deepwater pipe
coating and insulation project that was substantially completed during the year.

To help shape decision-making at every step, we use a highly-trained, multi-level sales force structured around target
markets and key accounts, focusing on engineers, contractors, consultants, administrators, technical staff and public officials.
Due to the technical nature of our products and services, many of our sales personnel have engineering or technical expertise
and experience. We also produce sales literature and presentations, participate in trade shows, present at conferences and
execute other marketing programs for our own sales force and those of unaffiliated licensees. Our unaffiliated licensees are
responsible for marketing and sales activities in their respective territories. See “Licensees” and “Ownership Interests in
Operating Licensees and Joint Ventures” above for a description of our licensing operations and for a description of
investments in licensees.

Contract Backlog

Contract backlog is our expectation of revenues to be generated from received, signed and uncompleted contracts, the

cancellation of which is not anticipated at the time of reporting. We assume that these signed contracts are funded. For
government or municipal contracts, our customers generally obtain funding through local budgets or pre-approved bond
financing. We generally do not undertake a process to verify funding status of these contracts and, therefore, cannot reasonably
estimate what portion, if any, of our contracts in backlog have not been funded. However, we have little history of signed
contracts being canceled due to the lack of funding. Contract backlog excludes any term contract amounts for which there are
not specific and determinable work releases and projects where we have been advised that we are the low bidder, but have not
formally been awarded the contract.

In accordance with industry practice, substantially all of our contracts are subject to cancellation, termination or suspension

at the discretion of the customer. Contracts in our backlog are subject to changes in scope and of services to be provided as
well as adjustments to the costs relating to the contracts. Accordingly, backlog is not necessarily indicative of our future
revenues or earnings.

Included within backlog for Energy Services are amounts that represent expected revenues to be realized under long-term

Master Service Agreements (“MSAs”) and other signed contracts. If the remaining term of these arrangements exceeds 12
months, the unrecognized revenues attributable to such arrangements included in backlog are limited to only the next 12
months of expected revenues. Although backlog represents only those contracts and MSAs that are considered to be firm, there
can be no assurance that cancellation or scope adjustments will not occur with respect to such contracts.

Included within backlog for Infrastructure Solutions and Corrosion Protection are certain contracts that are performed

through our variable interest entities in which we own a controlling portion of the entity. With the exception of Energy
Services, a substantial majority of our contracts in these two segments are fixed price contracts with individual private
businesses and municipal and federal government entities across the world. Energy Services generally enters into cost
reimbursable contracts that are based on costs incurred at agreed upon contractual rates.

For additional information regarding our backlog including those risk factors specific to backlog, please refer to “Risk
Factors” in Item 1A, and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Item 7
below.

Manufacturing and Suppliers

We maintain our North American Insituform® CIPP process liner manufacturing facility in Batesville, Mississippi. In
Europe, we manufacture and sell Insituform® CIPP process liners from our plant located in Wellingborough, United Kingdom.
Although raw materials used in Insituform® CIPP process products are typically available from multiple sources, our historical
practice has been to purchase materials from a limited number of suppliers. We maintain our own felt manufacturing facility in
Batesville, Mississippi. Substantially all of our fiber requirements are purchased from two sources, but there are alternate
vendors readily available. We source our global resin supply from multiple vendors. We also manufacture certain equipment

used in our Insituform® CIPP business. We believe that the sources of supply for our Insituform® CIPP operations in North
America, Europe and Asia-Pacific are adequate for our needs.

We sell Insituform® CIPP process liners and related products to third parties and certain licensees on a long-term or, in
certain instances, on a project-by-project basis. In Europe, in addition to sales made on a project-by-project basis, we have
entered into supply agreements with three third parties to supply them with Insituform® CIPP process liners and related
products.

With regard to Underground Solutions, we have three qualified third-party extruders to manufacture our Fusible PVC®

pipe products.

The principal raw materials used by Fyfe Co. in the manufacture of FRP composite materials are carbon, glass, resins,
fabric and epoxy raw materials. Fabric and epoxies are the most significant materials purchased, which are currently purchased
through a select group of suppliers, although these and the other materials are available from a number of vendors. The
weaving of FRP components into woven fabric is done at our facility in La Conner, Washington. Fyfe Co. does specialized
blending of unique epoxies from basic chemicals at our Batesville, Mississippi facility. The epoxy resin is also repackaged at
our Batesville, Mississippi facility, and specialized blending is also often done on each job site. Fyfe Co. also sells finished
materials throughout the United States and worldwide to our affiliates and certain certified third-party applicators.

Product and material revenues for our Corrpro business are derived principally from the sale of products that are purchased

from select outside vendors or from assembling components that are sourced from suppliers. We conduct light assembly for a
number of our Corrpro products in our production facilities in Sand Springs, Oklahoma; Edmonton, Alberta, Canada; and the
United Kingdom. In addition, we manufacture our own line of rectifiers and other power supplies in Canada and the United
Kingdom. The primary products and raw materials used by our Corrpro businesses include zinc, aluminum, magnesium and
other metallic anodes, as well as wire and cable. We maintain relationships with multiple vendors for these products and are
not dependent on any single vendor to meet our supply needs.

The product and service revenues for our United Pipeline Systems business are derived primarily from the procurement

and installation of HDPE liners inside pipelines. The raw material used for these liners is extruded thermoplastic pipe. It has
been our practice to purchase this material from a select group of suppliers; however, we believe that it is available from many
other sources. We manufacture most of the proprietary equipment and many of the consumable items used in Tite Liner®
system installations in our own facilities in Canada, the United States and Chile.

Product and service revenues for our ACS business is derived principally from internal and external pipeline coating.
Facilities are located in Tulsa, Oklahoma, Conroe, Texas and Saudi Arabia. The primary raw materials used in the coating
process include FBE and paint. Although our historical practice has been to purchase materials from a limited number of
suppliers, we believe that the raw materials used in the coating process are typically available from multiple sources. However,
in certain limited circumstances, our customer has required use of a specific material available from only a single source.

Our pricing of raw materials is subject to fluctuations in the underlying commodity prices. See “Commodity Risk” in Item

7A of this Report for detail on our management of the risks associated with such price fluctuations.

Patents and Proprietary Technologies

As of December 31, 2018, we held 32 United States patents relating to the Insituform® CIPP process. As of December 31,

2018, we had seven pending United States patent applications relating to the Insituform® CIPP process.

We have obtained and are pursuing patent protection in our principal foreign markets covering various aspects of the
Insituform® CIPP process. As of December 31, 2018, there were 87 issued foreign patents relating to the Insituform® CIPP
processes, and 15 applications pending in foreign jurisdictions. Of the applications pending in foreign jurisdictions, one is a
Patent Cooperation Treaty (“PCT”) application that covers most jurisdictions throughout the world and one is a European
Patent Convention (“EPC”) application that covers multiple jurisdictions in Europe.

As of December 31, 2018, we held 15 United States patents and 13 foreign patents with regard to Fusible PVC® pipe
products and fusion processes as well as other infrastructure technologies for water, wastewater and conduit applications that
relate to our Fusible PVC® pipe lining business.

As of December 31, 2018, we held 16 issued patents and two pending patent applications in the United States and eight

issued patents and five pending patent applications in foreign jurisdictions that relate to our Tyfo® system. Of these
applications, one is an EPC application that covers multiple jurisdictions in Europe.

For our coating operations, as of December 31, 2018, we held seven issued patents and four pending patent applications in
the United States and 10 issued patents and six pending patent applications in foreign jurisdictions. Of the foreign applications,
one is a PCT application that covers most jurisdictions throughout the world.

As of December 31, 2018, we had five issued patents and one pending patent application in the United States, and nine
issued patents and six pending patent applications in foreign jurisdictions that relate to the Tite Liner® process. Of the foreign
applications, one is an EPC application that covers multiple jurisdictions in Europe.

For our cathodic protection operations, as of December 31, 2018, we have three pending patent applications in the United

States and two pending applications in foreign jurisdictions. Of the foreign applications, one is a PCT application that covers
most jurisdictions throughout the world.

The specifications and/or rights granted in relation to each patent will vary from jurisdiction to jurisdiction. In addition, as

a result of differences in the nature of the work performed and in the climate of the countries in which the work is carried out,
we do not necessarily seek patent protection for all of our inventions in every jurisdiction in which we do business.

There can be no assurance that the validity of our patents will not be successfully challenged. Our business could be
adversely affected by increased competition upon expiration of the patents or if one or more of our patents were adjudicated to
be invalid or inadequate in scope to protect our operations. We believe in either case that our long experience with the
proprietary processes, the strength of our trademarks and our degree of market penetration should enable us to continue to
compete effectively in the pipeline rehabilitation, corrosion protection, energy, mining and infrastructure protection markets.

In some instances throughout each of our three platforms, we have elected to maintain certain internally developed
technologies, know-how and inventions as trade secrets. We have entered into confidentiality agreements with employees,
consultants and third parties to whom we disclose such trade secrets. Although there can be no assurance that these measures
will suffice to prevent unauthorized disclosure or use or that third parties will not develop similar technologies, we believe it
would take substantial time and resources to independently develop such technologies.

See “Risk Factors” in Item 1A of this Report for further discussion.

Competition

The markets in which we operate are highly competitive, primarily on the basis of price, quality of service and capacity to
perform. Many of our products and services face direct competition from competitors offering similar or essentially equivalent
products or services. In addition, customers can select a variety of methods to meet their infrastructure installation,
strengthening and rehabilitation needs, as well as their coating and cathodic protection needs, including a number of methods
that we do not offer.

In the trenchless wastewater rehabilitation market, the CIPP process is one of the preferred rehabilitation methods.
Because relatively few significant barriers to entry exist in this market, any organization with adequate financial resources and
access to technical expertise may become a competitor. As such, there are numerous companies with which we compete.
Worldwide, we compete with numerous smaller firms on local or regional levels and with several larger firms on the global and
national levels. Despite the number of competitors, Insituform®, as the worldwide pioneer of this technology, has maintained
its role as a global market leader, both in the United States and abroad.

In water rehabilitation, dig-and-replace is still the preferred method for the majority of customers. Currently, we believe
CIPP is utilized in less than 5% of water pipeline rehabilitation projects in the United States. Because this is a more specialized
field, with more barriers to entry, including strict government mandates, we compete primarily with a handful of global and
national specialty contractors.

Our Fusible PVC® products compete against other more-traditional products in the pressure pipe market, such as HDPE

and other restrained joint PVC pipe products.

In our infrastructure rehabilitation business, the FRP process competes against traditional methods of pipeline and

structural retrofitting, but is gaining acceptance in the construction and retrofitting industries. With its proprietary technologies
relating to both products and application, Fyfe Co. is a leader in the FRP market and Fibrwrap Construction, having
successfully performed installations of FRP systems for 25 years, is one of the most experienced applicators of the Tyfo®
system and has a well-established reputation. In this field, there are barriers to entry, including testing requirements,
experience, intellectual property and certifications. Fyfe has teamed with a number of universities around the world to conduct
extensive product testing. In addition, Fyfe has dedicated significant resources to obtaining technical market acceptance of its
proprietary products. As a result, Fyfe has received a number of certifications, including NSF certification for its Tyfo® system;
International Code Council - Evaluation Service Report (ESR-2103), indicating product approval by the International Building
Code; and compliance with ICC-AC125 guidelines for FRP strengthening. Because of the barriers to entry, Fyfe Co. and
Fibrwrap Construction tend to compete with a small number of companies on a regional or national level, most of which do not
provide the full spectrum of services provided by Fyfe Co. and Fibrwrap Construction.

In our Corrosion Protection segment, Corrpro operates in the highly-competitive field of cathodic protection for corrosion

control. While this market is highly competitive, because there are relatively few barriers to entry, Corrpro is a recognized
market leader in North America in this field. Competitors include a limited number of large firms, which provide services

nationally and, in some instances, globally, although more prevalent are a number of small- and medium-sized firms with more
limited portfolios of products and services, which are only provided on a regional or local level. Corrpro’s competitive
advantage is its broad depth of high-quality cathodic protection offerings, including its cost-effective engineering, pipeline
integrity, construction and coating services, which are provided to customers worldwide.

The process of utilizing thermoplastic liners is a prevalent method used to protect pipelines servicing the energy and
mining industries. United Pipeline Systems is recognized as a leader in the thermoplastic market, having provided relining
solutions on six continents. Due to barriers to entry arising from necessary technological capabilities, United Pipeline Systems
mainly competes with a small number of specialty firms globally, nationally and regionally. Through our focused efforts on
expanding our services worldwide, United Pipeline Systems enjoys significant name recognition and substantial market share
in this industry in the key energy and mining regions of the world.

ACS has a strong presence in the field of FBE coating and is an industry leader in both inner diameter robotic coatings and
outer diameter coatings. Because of these specialized fields, ACS usually competes with a small number of specialty providers.

Aegion Energy Services operates in a fragmented and intensely competitive field of plant maintenance and construction
and specialty services in the downstream oil refining industry, as well as performing work in the industrial and natural gas, gas
processing and compression markets. Competitors may be local, regional or national contractors and service providers and
vary with the markets that are served, with few competitors competing in all of the geographic markets we serve or offering all
of the services we provide. With the implementation of the California Refinery Safety Law, competition at refineries in
California is from building trade union contractors or, in some instances, from customers themselves expanding their own
workforces to reduce reliance on contractors. Contracts are generally awarded based on safety performance, reputation for
quality, price, schedule and client satisfaction. However, with the new California Refinery Safety Law in place, the trade
unions have increasing influence in the California labor market and on union contractors. Issues around labor relations and
access to supplemental labor are new factors affecting client decisions in selecting contractors.

There can be no assurance as to the success of our processes in competition with our competitors and alternative

technologies for pipe installation and rehabilitation, coating, cathodic protection and infrastructure installation, strengthening
and rehabilitation.

Seasonality

Our operations can be affected by seasonal variations and our results tend to be stronger in the second and third quarters of

each year due to typically milder weather in the regions in which we operate. We are more likely to be impacted by weather
extremes, such as excessive rain, hurricanes or monsoons, snow and ice or frigid temperatures, which may cause temporary,
short-term anomalies in our operational performance in certain localized geographic regions. However, these impacts usually
have not been material to our operations as a whole. See “Risk Factors” in Item 1A of this Report for further discussion.

Employees

As of December 31, 2018, we had approximately 5,350 employees. Certain of our subsidiaries are parties to collective

bargaining agreements that covered an aggregate of approximately 1,500 employees as of December 31, 2018. We generally
consider our relations with our employees and unions to be good.

Insurance and Bonding

We are required to carry insurance and provide bonding in connection with certain projects and, accordingly, maintain
comprehensive insurance policies, including workers’ compensation, general and automobile liability and property coverage.
We believe that we presently maintain adequate insurance coverage for all operations. We have also arranged bonding capacity
for bid, performance and payment bonds. Typically, the cost of a performance bond is less than 1% of the contract value. We
are required to indemnify the surety companies against losses from third-party claims of customers and subcontractors. The
indemnification obligations are collateralized by unperfected liens on our assets and the assets of those subsidiaries that are
parties to the applicable indemnification agreement.

Government Regulation

We are required to comply with all applicable United States federal, state and local, and all applicable foreign statutes,

regulations and ordinances. In addition, our installation and other operations have to comply with various relevant
occupational safety and health regulations, transportation regulations, code specifications, permit and licensing requirements
and bonding and insurance requirements, as well as with fire regulations relating to the storage, handling and transporting of
flammable materials. Our manufacturing and coatings facilities, as well as our installation and other operations, are subject to
federal and state environmental protection regulations, none of which presently have any material effect on our capital
expenditures, earnings or competitive position in connection with our present business. However, although our installation and
other operations have established monitoring programs and safety procedures, further restrictions could be imposed on the
manner in which installation and other activities are conducted, on equipment used in installation and other activities, on

volatile organic compounds and hazardous air pollutant emissions from our paintings and coatings processes and on the use of
solvents or the thermosetting resins used in the Insituform® CIPP process.

The use of both thermoplastics and thermosetting resin materials in contact with drinking water is strictly regulated in most

countries. In the United States, a consortium led by NSF International, under arrangements with the United States
Environmental Protection Agency (“EPA”), establishes minimum requirements for the control of potential human health effects
from substances added indirectly to water via contact with treatment, storage, transmission and distribution system
components, by defining the maximum permissible concentration of materials that may be leached from such components into
drinking water, and methods for testing them. Our lining and coating products for drinking water use are NSF/ANSI Standard
61 compliant, including the entire Tyfo® system, the full range of Insituform® water pipe lining products and our Fusible
C-900® and Fusible C-905® products. In addition, our Tite Liner® HDPE system is certified to NSF/ANSI Standard 61.
Corrpro’s corrosion control products are NSF/ANSI Standard 61 classified for drinking water systems and its cathodic
protection solutions for water storage tanks and water treatment units are compliant with AWWA Standard D104 and NACE
recommended practices. NSF assumes no liability for use of any products, and NSF’s arrangements with the EPA do not
constitute the EPA’s endorsement of NSF, NSF’s policies or its standards. Dedicated equipment is needed in connection with
use of these products in drinking water applications.

Item 1A. Risk Factors.

You should carefully consider the following risks and other information contained or incorporated by reference into this

Report when evaluating our business and financial condition and an investment in our common stock. Should any of the
following risks or uncertainties develop into actual events, such developments could have material adverse effects on our
business, financial condition, cash flows and results of operations.

Our businesses face significant competition in the industries in which they operate.

Many of our products and services face direct competition from companies offering similar products or services.
Competition can place downward pressure on our contract prices and profit margins. Intense competition is expected to
continue in these markets. If we are unable to realize our objectives, we could lose market share to our competitors and
experience an overall reduction in our profits.

In the water and wastewater rehabilitation portion of our Infrastructure Solutions segment, we face competition from
companies providing similar products and services as well as companies providing other methods of rehabilitation that we do
not offer, including traditional dig-and-replace, which is still the preferred method in the water rehabilitation market. In the
trenchless wastewater rehabilitation market, CIPP is one of the preferred methods. In this market, few significant barriers to
entry exist and, as a result, any organization that has the financial resources and access to technical expertise and bonding may
become a competitor. As such, we compete with many smaller firms on a local or regional level and with several larger firms
on the global and national levels. In water rehabilitation, where there are more significant barriers to entry because the market
is strictly regulated, we compete with a smaller number of specialty contractors around the world. Further, our Fusible PVC®
pipe products compete against other more traditional products, such as HDPE and restrained joint PVC pipe products.

In the infrastructure rehabilitation portion of our Infrastructure Solutions segment, the Tyfo® system competes against
traditional methods of structural retrofitting. There are significant barriers to entry, including testing requirements, experience,
intellectual property and certifications. In manufacturing, we only compete with a handful of FRP suppliers. However, with
respect to installation, we compete with a number of FRP applicators. Our ability to grow revenues in this market could be
adversely impacted if any of our competitors were to become fully-integrated like us or if new entrants in the market were to
develop strong installation and manufacturing expertise.

In our Corrosion Protection platform, we compete primarily with specialty firms in the pipeline protection industry and
both a limited number of large firms globally and a large number of smaller firms regionally in the cathodic protection industry.
In addition, customers can select a variety of methods to meet their pipe installation, rehabilitation, coating and cathodic
protection needs, including methods that we do not offer.

In our Energy Services platform, we compete with a limited number of local, regional and national companies in the oil

and gas procurement, construction, maintenance, scaffolding and turnaround industries on the U.S. West Coast.

Our business depends upon the maintenance of our proprietary technologies and information.

We depend on our proprietary technologies and information, many of which are no longer subject to patent protection. We

rely principally upon trade secret and copyright laws to protect our proprietary technologies. We regularly enter into
confidentiality agreements with our key employees, customers, potential customers and other third parties and limit access to
and distribution of our trade secrets and other proprietary information. However, these measures may not be adequate to
prevent misappropriation of our technologies or to assure that our competitors will not independently develop technologies that
are substantially equivalent or superior to our technologies. In addition, the laws of other countries in which we operate may

not protect our proprietary rights to the same extent as the laws of the United States. We are also subject to the risk of adverse
claims and litigation alleging infringement of intellectual property rights.

Our efforts to develop new products and services or enhance existing products and services involve substantial research,
development and marketing expenses, and the resulting new or enhanced products or services may not generate
sufficient revenues to justify such expenses.

Our future success will depend in part on our ability to anticipate and respond to changing technologies and customer

requirements by enhancing our existing products and services. We will need to develop and introduce, on a timely and cost-
effective basis, new products, features and services that address the needs of our customer base. As a result of these efforts, we
may be required to expend substantial research, development and marketing resources, and the time and expense required to
develop a new product or service or enhance an existing product or service are difficult to predict. We cannot assure that we
will succeed in developing, introducing and marketing new products or services or product or service enhancements. In
addition, we cannot be certain that any new or enhanced product or service will generate sufficient revenues to justify the
expenses and resources devoted to this product development and enhancement effort.

Acquisitions and investments could result in operating difficulties, dilution and other harmful consequences that may
adversely impact our business and results of operations.

Acquisitions are an element of our overall corporate strategy and use of capital, and these transactions could be material to
our financial condition and results of operations. We expect to continue to evaluate and enter into discussions regarding a wide
array of potential strategic transactions. The process of integrating an acquired company, business or technology has created,
and will continue to create, unforeseen operating difficulties and expenditures. The areas where we face risks include:

• Diversion of management time and focus from operating our business to acquisition integration challenges.

• Failure to successfully operate and further develop the acquired business or technology.

•

Implementation or remediation of controls, procedures and policies at the acquired company.

Integration of the acquired company’s accounting, human resource and other administrative systems, and
coordination of product, engineering and sales and marketing functions.

• Transition of operations, users and customers onto our existing platforms.

• Failure to obtain required approvals or consents on a timely basis, if at all, including from governmental authorities or
contractual counter-parties, or conditions placed upon approval or consent, including under competition and antitrust
laws, which could, among other things, delay or prevent us from completing a transaction, or otherwise restrict our
ability to realize the expected financial or strategic goals of an acquisition.

•

In the case of foreign acquisitions, the need to integrate operations across different cultures and languages and to
address the particular economic, currency, political and regulatory risks associated with specific countries.

• Cultural challenges associated with integrating employees from the acquired company into our organization, and

retention of key employees from the businesses we acquire.

• Liability for activities of the acquired company before the acquisition, including patent and trademark infringement

claims, violations of laws, commercial disputes, tax liabilities and other known and unknown liabilities.

• Assumption of contracts with terms, including, without limitation, terms relating to liability, waiver of damages and

indemnification, that are not consistent with our normal contracting practices.

• Litigation or other claims in connection with the acquired company, including claims from terminated employees,

customers, former stockholders or other third parties.

Our failure to address these risks or other problems encountered in connection with our past or future acquisitions and
investments could cause us to fail to realize the anticipated benefits of such acquisitions or investments, incur unanticipated
costs or liabilities, and harm our business generally.

Our acquisitions could also result in dilutive issuances of our equity securities, the incurrence of debt, the assumption of
contingent liabilities, amortization expenses, impairment of goodwill and purchased long-lived assets and restructuring charges,
any of which could harm our financial condition or results of operations. Also, the anticipated benefit of many of our
acquisitions may not materialize for reasons separate and apart from the specific risks set forth above.

We may be liable to complete the work of our joint venture partners under our joint venture arrangements.

We enter into contractual joint ventures in order to develop joint bids on certain contracts. The success of these joint
ventures depends largely on the satisfactory performance by our joint venture partners of their obligations with respect to the

joint venture. Under these joint venture arrangements, we may be required to complete our joint venture partner’s portion of
the contract if the joint venture partner is unable to complete its portion and a bond is not available. In such case, the additional
obligations could result in reduced profits or, in some cases, significant losses for us.

Our backlog is an uncertain indicator of our future earnings.

Our backlog, which at December 31, 2018 was approximately $669.4 million, is subject to unexpected adjustments and
cancellation. The revenues projected in this backlog may not be realized or, if realized, may not result in profits. We may be
unable to complete some projects included in our backlog in the estimated time and, as a result, such projects could remain in
backlog for extended periods of time. Further, our customers often have the contractual right to terminate our contract or
reduce our scope of our work at the convenience of the customer. To the extent that we experience project or contract
cancellation or scope adjustments, we could face a reduction in the dollar amount of our backlog and the revenues that we
actually receive from such backlog. In addition, one or more of our large or multi-year contracts have in the past and may in
the future contribute a material portion of our backlog in any one year. The loss of business from any one of these significant
customers could have a material adverse effect on our business or results of operations.

The preparation of our consolidated financial statements requires us to make estimates and judgments, which are
subject to an inherent degree of uncertainty and which may differ from actual results.

Our consolidated financial statements are prepared in accordance with accounting principles generally accepted in the
United States, which require us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues
and expenses and related disclosure of contingent assets and liabilities. Some accounting policies require the application of
significant judgment by management in selecting the appropriate assumptions for calculating financial estimates. By their
nature, these estimates and judgments are subject to an inherent degree of uncertainty and actual results may differ from these
estimates and judgments under different assumptions or conditions, which may have an adverse effect on our financial
condition or results of operations in subsequent periods.

Our use of input measures to recognize revenue on construction, engineering and installation services could result in a
reduction or reversal of previously recorded results.

Revenues from construction, engineering and installation services are recognized over time using an input measure to
measure progress toward satisfying performance obligations. This methodology recognizes revenues and profits over the life of
a project based on costs incurred to date compared to total estimated project costs. Revisions to revenues and profits are made
once amounts are known and can be reasonably estimated. Given the uncertainties associated with some of our contracts, it is
possible for actual costs to vary from estimates previously made. Revisions to estimates could result in the reversal of revenues
and gross profit previously recognized. For the year ended December 31, 2018, approximately 65% of our revenues were
derived from accounting utilizing estimated input measures.

We may experience cost overruns on our projects.

We conduct a significant portion of our business under guaranteed maximum price or fixed price contracts, where we bear

a significant portion of the risk for cost overruns. Under such contracts, prices are established in part on cost and scheduling
estimates, which are based on a number of assumptions, including assumptions about future economic conditions, prices and
availability of materials and other exigencies. Our profitability depends heavily on our ability to make accurate estimates.
Inaccurate estimates, or changes in other circumstances, such as unanticipated technical problems, difficulties obtaining permits
or approvals, changes in local laws or labor conditions, weather delays, cost of raw materials, trade disputes and tariffs,
currency fluctuations or our suppliers’ or subcontractors’ inability to perform could result in substantial losses, as such changes
adversely affect the revenues and gross profit recognized on each project.

Our recognition of revenues from change orders, extra work or variations in the scope of work could be subject to
reversal in future periods.

We recognize revenues from change orders, extra work or variations in the scope of work as set forth in our written

contracts with our clients when management believes that realization of these revenues is probable and the recoverable amounts
can be reasonably estimated. We also factor in all other information that we possess with respect to the change order to
determine whether the change order should be recognized at all and, if recognition is appropriate, what dollar amount of the
change order should be recognized. Due to factors that we may not anticipate at the time of recognition, however, revenues
ultimately received on these change orders could be less than revenues that we recognized in a prior reporting period or periods,
which could require us in subsequent reporting periods to reduce or reverse revenues and gross profit previously recognized.

We may incur significant costs in providing services in excess of original project scope without having an approved
change order.

After commencement of a contract, we may perform, without the benefit of an approved change order from the customer,

additional services requested by the customer that were not contemplated in our contract price for various reasons, including

customer changes, incomplete or inaccurate engineering, changes in project specifications and other similar information
provided to us by the customer. Our construction contracts generally require the customer to compensate us for additional work
or expenses incurred under these circumstances.

A failure to obtain adequate compensation for these matters could require us to record in the current period an adjustment

to revenues and profit recognized in prior periods under the percentage-of-completion accounting method. Any such
adjustments, if substantial, could have a material adverse effect on our results of operations and financial condition, particularly
for the period in which such adjustments are made. We can provide no assurance that we will be successful in obtaining,
through negotiation, arbitration, litigation or otherwise, approved change orders in an amount adequate to compensate us for
our additional work or expenses.

Cyclical downturns in the mining, oil and natural gas industries, including a substantial or extended decline in the price
of mined minerals, oil or natural gas, or in the oil field, refinery and mining services businesses, may have a material
adverse effect on our financial condition or results of operations.

The mining, oil and natural gas industries are highly cyclical. Demand for the majority of the oil field, refinery and mining
products and services provided by our Corrosion Protection and Energy Services platforms are substantially dependent on the
level of expenditures by the mining, oil and natural gas industries for the exploration, development and production of mined
minerals, crude oil and natural gas reserves, which are sensitive to the prices of these commodities and generally dependent on
the industry’s view of future mined mineral, oil and natural gas prices. The prices of these commodities can be volatile. There
are numerous factors affecting the related industries and, thereby, the supply of, and demand for, our products and services,
which include, but are not limited to:

• market prices of mined minerals, oil and natural gas and expectations about future prices;

• cost of producing mined minerals, oil and natural gas;

•

the level of mining, drilling and production activity;

the discovery rate of new oil and gas reserves;

• mergers, consolidations and downsizing among our clients;

• coordination by various oil-producing countries, including the Organization of Petroleum Exporting Countries

(OPEC);

the output and willingness to export of certain oil-producing countries;

the impact of commodity prices on the expenditure levels of our clients;

financial condition of our client base and their ability to fund capital and maintenance expenditures;

•

• political instability in oil-producing countries;

•

tax incentives, including for alternative energy sources;

• domestic and worldwide economic conditions;

• adverse weather conditions, including those that can affect mining, oil or natural gas operations over a wide area;

• availability of energy sources other than oil and gas;

•

level of consumption of minerals, oil, natural gas and petrochemicals by consumers, including the effects of increased
regulation, conservation measures and technological advances affecting energy consumption; and

• availability of services and materials for our clients to grow their capital expenditures.

As seen in the historic high volatility in crude oil prices and other energy commodities, prices for mined minerals, oil and

natural gas are subject to periodic downturns and large fluctuations in response to relatively minor changes in supply and
demand, market uncertainty and a variety of other factors (including those set forth above) that are beyond our control, and we
expect such prices to continue to be volatile. Demand for the products and services we provide could decrease in the event of a
sustained reduction in demand for mined minerals, oil or natural gas, while perceptions of long-term decline in the prices of
mined materials, oil and natural gas by mining, oil and gas companies (some of our customers) can similarly reduce or defer
major expenditures given the long-term nature of many large-scale projects or result in downward pressure on the prices we
charge. As such, a significant downturn in the mining, oil and/or natural gas industries could result in a reduction in demand
for our mining, oil field and refinery services and could adversely affect our operating results. Additionally, the volatility of
such prices and the resulting effects are difficult to predict, which reduces our ability to anticipate and respond effectively to
changing conditions.

Our operations could be adversely impacted by the California Refinery Safety Law related to downstream work
performed in California refineries.

Aegion Energy Services continues to face challenges from the impact of the California Refinery Safety Law, which went

into effect on January 1, 2014. The law introduced new requirements for refineries and outside contractors at covered facilities
18

when construction, alteration, demolition, installation, repair or maintenance work is performed at the covered facility. The law
imposes the following requirements:

• all subject workers must be paid the applicable prevailing wage rate;

• all subject workers must be either “skilled journeymen” or “registered apprentices”; and

• at least 60% of skilled journeypersons on the project must be graduates of certified apprenticeship programs.

The effect of the California Refinery Safety Law is to require the use of building trade union contractors or refinery owners

or operators to perform the covered work.

These requirements only pertain to contracts entered into, extended or renewed after January 1, 2014. Contracts entered

into, extended or renewed prior to that date generally expired in 2018 across the industry. Aegion Energy Services has
historically had long-term contracts in place with many of its major downstream clients, which it intends to maintain through its
building trade union entity. Throughout 2018, Aegion Energy Services was able to transition its contracts with all of its
California refinery clients to its building trade union entity in order to satisfy the conditions of the California Refinery Safety
Law. However, as a result of this drastic change in the market in California, customers are looking at ways to reduce costs. For
example, many clients are reevaluating their contracting strategies and have reduced, or may in the future reduce, the size of
their contractor maintenance crews by increasing their own in-house maintenance capabilities. There are no assurances that
clients will maintain their contracts, or the historical annual volume of work, with Aegion Energy Services as the industry
adapts to operating under the California Refinery Safety Law, which could materially and adversely impact its revenues.

Federal and state legislative and regulatory initiatives as well as governmental reviews relating to hydraulic fracturing
could result in increased costs and additional operating restrictions or delays that could adversely affect our Corrosion
Protection customers.

Federal, state and local legislative and regulatory initiatives relating to hydraulic fracturing could result in increased costs

and additional operating restrictions or delays in the production of oil and natural gas, including from the developing shale
plays. Our Corrosion Protection segment services oil and gas companies in the shale plays and we foresee strong market
opportunities here. A decline in drilling of new wells and related servicing activities caused by these initiatives could have an
adverse effect on our business, financial position or results of operations.

We may be subject to liabilities under environmental laws and regulations.

Our services are subject to numerous U.S. and international environmental protection laws and regulations that are

complex and stringent. For example, we must comply with a number of U.S. federal government laws that strictly regulate the
handling, removal, treatment, transportation, and disposal of toxic and hazardous substances. Under the Comprehensive
Environmental Response Compensation and Liability Act of 1980, as amended (“CERCLA”), and comparable state laws, we
may be required to investigate and remediate regulated hazardous materials. CERCLA and comparable state laws typically
impose strict, joint and several liabilities without regard to whether a company knew of or caused the release of hazardous
substances. The liability for the entire cost of clean-up could be imposed upon any responsible party. Other principal U.S.
federal environmental, health, and safety laws affecting us include, but are not limited to, the Resource Conservation and
Recovery Act, National Environmental Policy Act, the Clean Air Act, the Occupational Safety and Health Act, the Federal Mine
Safety and Health Act of 1977, the Toxic Substances Control Act, and the Superfund Amendments and Reauthorization Act.
Our business operations may also be subject to similar state and international laws relating to environmental protection.
Further, past business practices at companies that we have acquired may also expose us to future unknown environmental
liabilities. Liabilities related to environmental contamination or human exposure to hazardous substances, or a failure to
comply with applicable regulations, could result in substantial costs to us, including clean-up costs, fines, civil or criminal
sanctions, and third-party claims for property damage or personal injury or cessation of remediation activities. Our continuing
work in the areas governed by these laws and regulations exposes us to the risk of substantial liability.

The effects of the Tax Cuts and Jobs Act on our business are still not fully known and could have an adverse effect on
our business and financial condition.

Public Law No. 115-97, commonly referred to as the Tax Cuts and Jobs Act (the “TCJA”), was signed into law on
December 22, 2017. The TCJA contains significant changes to corporate taxation, including reducing the corporate tax rate
from 35% to 21%, limiting the tax deduction for interest expense to 30% of earnings (except for certain small businesses),
limiting the deduction for net operating losses to 80% of current year taxable income and eliminating net operating loss
carrybacks, one-time taxing of offshore earnings at reduced rates regardless of whether they are repatriated, eliminating U.S.
tax on foreign earnings (subject to certain important exceptions), immediately deducting certain new investments instead of
deducting depreciation expense over time, and modifying or repealing many business deductions and credits. We anticipate
additional guidance, both at the federal and state level, to be forthcoming in 2019. As such, the impacts of the legislation may

differ from our current estimates, interpretations and assumptions, possibly materially, and the amount of the impact on the
Company may accordingly be adjusted over the course of 2019.

A general downturn in U.S. and global economic conditions, specifically a downturn in the municipal bond market, or
government disruptions, including government shutdowns, may reduce our business prospects and decrease our
revenues and cash flows.

Our business is affected by general economic conditions. Any extended weakness in the U.S. and global economies could
reduce our business prospects and could cause decreases in our revenues and operating cash flows. Specifically, a downturn in
the municipal bond market caused by an actual downgrade of monoline insurers could result in our municipal customers being
required to spend municipal funds previously allocated to projects that would benefit our business to pay off outstanding bonds.
A period of prolonged economic weakness could impact our customers’ ability to pay bills in a timely manner and may result in
customer bankruptcies. Untimely payment and customer bankruptcies may lead to increased bad debt expenses or other
adverse effects on our financial position, results of operations and/or cash flows. In addition, government disruptions, such as
government shutdowns, may delay or halt the granting and renewal of permits, licenses and other items required by us and our
customers to conduct our business.

We conduct manufacturing, sales and distribution operations on a worldwide basis and are subject to a variety of risks
associated with doing business outside the United States.

We maintain significant international operations, including operations in North America, Europe, Asia-Pacific, the Middle

East and South America. For the years ended December 31, 2018, 2017 and 2016, approximately 28%, 24%, and 24%,
respectively, of our revenues were derived from international operations. We expect a significant portion of our revenues and
profits to come from international operations and joint ventures for the foreseeable future.

As a result, we are subject to a number of risks and complications associated with international manufacturing, sales,

services and other operations. These include:

• difficulties in enforcing agreements, collecting receivables and resolving disputes through some foreign legal

systems;

•

foreign customers with longer payment cycles than customers in the United States;

• difficulties in enforcing intellectual property rights or weaker intellectual property right protections in some countries;

•

tax rates in certain foreign countries that exceed those in the United States and foreign earnings subject to
withholding requirements;

tax laws that restrict our ability to use tax credits, offset gains or repatriate funds;

tax laws that impose additional taxes on our operations, including the implementation of value added tax in certain
countries in the Middle East;

sanctions, tariffs, exchange controls, trade disputes (including so-called “trade wars”) or other trade restrictions,
including transfer pricing restrictions, when products produced in one country are sold to an affiliated entity in
another country;

• difficulties with regard to, or taxes imposed on, the movement of cash between countries, including the repatriation of

cash back to the United States;

• abrupt changes in foreign government policies and regulations;

• unsettled political conditions;

• acts of terrorism or criminality;

• kidnapping of employees;

• nationalization or privatization of companies with which we do business;

• protectionist policies in certain foreign countries, including those in the Middle East, that disfavor foreign companies

•

operating in such countries;

forced negotiation or modification of contracts;

increased governmental ownership and regulation of markets in which we operate;

the financial instability of, and the related inability or unwillingness to timely pay for our services by, national oil
companies and other foreign customers resulting from, and/or exacerbated by, depressed oil prices;

• hostility from local populations, particularly in the Middle East;

•

tenuous, unstable or hostile relationships between countries that are interconnected in our operations; and

• difficulties associated with compliance with a variety of laws and regulations governing international trade, including

the Foreign Corrupt Practices Act.

To the extent that our international operations are affected by these unexpected and adverse foreign economic and political

conditions, we may experience project disruptions and losses that could significantly reduce our revenues and profits.

Implementation and achievement of international growth objectives also may be impeded by political, social and economic

uncertainties or unrest in countries in which we conduct operations or market or distribute our products. In addition,
compliance with multiple, and potentially conflicting, international laws and regulations, import and export limitations, anti-
corruption laws and exchange controls may be difficult, burdensome or expensive.

For example, we are subject to compliance with various laws and regulations, including the Foreign Corrupt Practices Act
and similar anti-bribery laws, which generally prohibit companies and their intermediaries from making improper payments to
officials for the purpose of obtaining or retaining business. While our employees and agents are required to comply with these
laws, we cannot provide assurance that our internal policies, procedures and controls will always protect us from violations of
these laws, despite our commitment to legal compliance and corporate ethics. The occurrence or allegation of these types of
risks may adversely affect our business, performance, prospects, value, financial condition and results of operations.

Operational disruptions caused by political instability and conflict in the Middle East, South America, Europe and Asia
could adversely impact our current operations and plans of expansion in these regions.

Our Corrosion Protection segment currently operates in the Middle East and South America, and our Infrastructure

Solutions segment currently operates in Europe and Asia. Political instability and social unrest in the Middle East, South
America, Europe and Asia (including export restrictions, trade and other sanctions, taxes, repatriations and nationalizations), as
well as the potential for catastrophic events such as abrupt political change, terrorist acts and conflicts or wars in these and
other regions may cause damage or disruption to the economy, financial markets and our current and prospective customers in
the these regions. Political instability, conflicts and the potential for catastrophic events have contributed to, and will likely
continue to contribute to, volatility in these regions, which could adversely affect our operations and operating results.

As a result of our operations in these regions, we are also exposed to certain other uncertainties not generally encountered

in our U.S. operations, including those detailed in the risk factor immediately above.

Business operations could be adversely affected by terrorism.

The threat of, or actual acts of, terrorism may affect our operations around the world in unpredictable ways and may force

an increase in security measures and cause disruptions in supplies and markets. If any of our facilities, including our
manufacturing facilities, or if any of the projects we are working on, particularly in the energy and mining sector, were to be a
direct target, or an indirect casualty, of an act of terrorism, our operations could be adversely affected. Corresponding
instability in the financial markets as a result of terrorism also could adversely affect our ability to raise capital.

We have international operations that are subject to foreign economic uncertainties and foreign currency fluctuation.

Global financial and credit markets have been, and continue to be, unstable and unpredictable. For example, in June 2016

the United Kingdom voted to exit the European Union (commonly referred to as “Brexit”), which has created significant
uncertainties affecting the economy and business operations, including our operations, in the United Kingdom and the
European Union. While the United Kingdom is currently scheduled to depart the European Union on March 29, 2019, the
terms of Brexit remain uncertain as the United Kingdom continues to negotiate the terms of its exit from the European Union
and, as such, it is difficult to predict the effect of Brexit on our Company and our operations in the United Kingdom, including
our operations in Northern Ireland and the Republic of Ireland, our manufacturing facility in Wellingborough, United Kingdom,
which distributes liners to the European Union and elsewhere, and our manufacturing facility in Stockton-on-Tees, United
Kingdom, which manufactures and distributes cathodic protection equipment worldwide. Brexit could, among other things,
affect the legal and regulatory schemes to which our operations in the United Kingdom are subject, adversely affect trade
between the United Kingdom and the European Union and continue to cause economic uncertainty. The instability of the
markets and weakness of the economy could affect the demand for our services, the financial strength of our customers and
suppliers, their ability or willingness to do business with us, our willingness to do business with them, and/or our suppliers’ and
customers’ ability to fulfill their obligations to us and/or the ability of us, our customers or our suppliers to obtain credit. These
factors could adversely affect our operations, earnings and financial condition.

A significant portion of our contracts and revenues are denominated in foreign currencies, which may result in additional
risk of fluctuating currency values and exchange rates, hard currency shortages and controls on currency exchange. Changes in
the value of foreign currencies could increase our U.S. dollar costs for, or reduce our U.S. dollar revenues from, our foreign
operations. Any increased costs or reduced revenues as a result of foreign currency fluctuations could affect our profits. For
example, Brexit has resulted in a sharp decline in the value of the British Pound as compared to the U.S. dollar and other major
currencies. If there is a significant strengthening of the U.S. dollar compared to the British pound, Euro, the Canadian dollar or
the Australian dollar, it may adversely affect our operating results and financial condition.

New tariffs and other trade restrictions may adversely affect our business and results of operations.

Certain of our businesses use, or depend on our customers’ access to, steel products, including steel pipe, that may be
imported into the United States from international markets. In 2018, the Trump Administration imposed certain new tariffs on,
among other things, steel products. These tariffs have increased prices for imported steel products and have led domestic
sellers to respond with market-based increases. In response, certain other countries have proposed responsive tariffs or other
trade restrictions on U.S. products.

These new tariffs and trade restrictions, along with any additional tariffs and restrictions that may be implemented by the

United States or other countries in the future, may result in further increased prices, decreased available supply of steel and
other materials used in our business and decreased demand for U.S. products internationally. We may not be able to pass any
resulting price increase on to our customers. Further, we, or our customers, may be unable to secure adequate supplies of steel
or other materials on a timely basis, which may reduce demand for our products and services. As a result, our business and
results of operations may be adversely affected.

An inability to attract and retain qualified personnel, and in particular, engineers, estimators, project managers, line
workers, skilled craft workers and other experienced professionals, could impact our ability to perform on our
contracts, which could harm our business and impair our future revenues and profitability.

Our ability to attract and retain qualified engineers, estimators, project managers, line workers, skilled craft workers and
other experienced professionals in accordance with our needs is an important factor in our ability to maintain profitability and
grow our business. The market for these professionals is competitive, particularly during periods of economic growth when the
supply is limited. We cannot provide any assurance that we will be successful in our efforts to retain or attract qualified
personnel when needed. Therefore, when we anticipate or experience growing demand for our services, we may incur
additional cost to maintain a professional staff in excess of our current contract needs in an effort to have sufficient qualified
personnel available to address this anticipated demand. If we do incur additional compensation and benefit costs, our customer
contracts may not allow us to pass through these costs. We may recruit skilled professionals from other countries to work in the
U.S., and from the U.S. and other countries to work abroad. Limitations imposed by immigration laws in the U.S. and abroad,
travel bans, and difficulties obtaining visas and other restrictions on international travel could hinder our ability to attract
necessary qualified personnel and harm our business and future operating results.

Competent and experienced engineers, project managers and craft workers are especially critical to the profitable
performance of our contracts, particularly on our fixed-price contracts where superior design or execution of the project can
result in profits greater than originally estimated or where inferior design or project execution can reduce or eliminate estimated
profits or even result in a loss. Our project managers are involved in most aspects of contracting and contract execution
including:

• supervising the bidding process, including providing estimates of significant cost components, such as material and

equipment needs, and the size, productivity and composition of the workforce;

• negotiating contracts;

• supervising project performance, including performance by our employees, subcontractors and other third-party

suppliers and vendors;

• estimating costs for completion of contracts that is used to estimate amounts that can be reported as revenues and

earnings on the contract under the percentage-of-completion method of accounting;

• negotiating requests for change orders and the final terms of approved change orders; and

• determining and documenting claims by us for increased costs incurred due to the failure of customers,

subcontractors and other third-party suppliers of equipment and materials to perform on a timely basis and in
accordance with contract terms.

The California Refinery Safety Law, which requires owners and operators to use only building trade union contractors for

covered work at the refineries (if not self-performed), has the potential to reduce, constrict or disrupt the entire labor pool for
refinery maintenance in California by: (i) eliminating the non-union workforce; and (ii) requiring the use of the same workforce
that also performs public works and general construction in California. This could adversely affect staffing for large turnaround
projects at California refineries. This could also adversely affect Energy Services’ ability to support turnaround and project
work outside California, due to its past reliance on its mobile California workforce to staff short term projects throughout the
West Coast. There will be a significant wage differential between high union wages in California and wages in other states on
the West Coast, creating a large disincentive for the California workforce to leave the state. The uncertainty created by this
industry workforce change has the potential to negatively impact the entire West Coast refinery labor market, which in turn
would negatively impact our revenues, profits and operations.

In addition, we use a multi-level sales force structured around target markets and key accounts, focusing on marketing our

products and services to engineers, consultants, administrators, technical staff and elected officials. We are dependent on our

personnel to continue to develop improvements to our proprietary processes, including materials used and the methods of
manufacturing, installing, strengthening, coating and cathodic protection and we require quality field personnel to effectively
and profitably perform our work. Our success in attracting and retaining qualified personnel is dependent on the resources
available in individual geographic areas and the impact on the labor supply of general economic conditions, as well as our
ability to provide a competitive compensation package and work environment. Our failure to attract, train, integrate, engage
and retain qualified personnel could have a significant effect on our financial condition and results of operations.

Our profitability could be negatively impacted if we are not able to maintain appropriate utilization of our workforce.

The extent to which we utilize our workforce affects our profitability. If we under-utilize our workforce, our project gross

margins and overall profitability suffer in the short term. If we over-utilize our workforce, we may also negatively impact
margins and overall profitability, as well as safety, employee satisfaction and project execution, which could result in an
increase in injuries to our employees and a decline of future project awards. The utilization of our workforce is impacted by
numerous factors including:

• our estimate of the headcount requirements for various units based on our forecast of the demand for our products

and services;

• our ability to maintain our talent base and manage attrition;

• our ability to schedule our portfolio of projects to efficiently utilize our employees and minimize downtime between

project assignments; and

• our need to invest time and resources into functions such as training, business development, employee recruiting, and

sales that are not chargeable to customer projects.

Our business may be adversely impacted by work stoppages, staffing shortages and other labor matters.

As of December 31, 2018, our Aegion Energy Services business had approximately 1,370 employees that were represented

by unions, although these numbers are constantly changing as customer demands change. Infrastructure Solutions has
approximately 130 employees represented by unions. Although we believe that our relations with our employees and the
unions are good, no assurances can be made that we will not experience these and other types of conflicts with labor unions,
works councils, other groups representing employees, or our employees in general, especially in the context of any future
negotiations with our labor unions. We can also make no assurance that future negotiations with our labor unions will not result
in a significant increase in the cost of labor. Approximately 70% of our Energy Services union employees currently participate
in multi-employer benefit plans, which is a result of the transition of many of our clients to our building trade union contracting
entity. The number of multi-employer plans in which our employees participate varies depending on how many local unions
we are using at any particular time, but it is usually between 20 and 30 multi-employer plans. Participation in multi-employer
benefit plans may result in liability to Aegion Energy Services in excess of that directly attributable to employees of Aegion
Energy Services.

Additionally, the employees of some of our customers are unionized, especially the customers of our Aegion Energy
Services business. Further, many of our customers’ union contracts will be renegotiated in 2019. Any strikes, work stoppages
or other labor matters experienced by our customers may impact our ability to work on projects and, as a result, have an
adverse effect on our financial condition and results of operations.

Finally, in certain areas of our business, most notably in our Corrosion Protection platform, our employees are not

represented by unions. As a result, we may not be eligible to bid or perform certain work that requires union labor, which may
have an adverse effect on our financial condition and results of operations.

The revenues from the water and wastewater portion of our Infrastructure Solutions platform are substantially
dependent on municipal government spending.

Many of our customers are municipal governmental agencies and, as such, we are dependent on municipal spending.
Spending by our municipal customers can be affected by local political circumstances, budgetary constraints and other factors.
Consequently, future municipal spending may not be allocated to projects that would benefit our business or may not be
allocated in the amounts or for the size of the projects that we anticipated. A decrease in municipal spending on such projects
would adversely impact our revenues, results of operations and cash flows.

The loss of one or more of our significant customers could adversely affect us.

One or more customers have in the past and may in the future contribute a material portion of our revenues in any one year.

Because these significant customers generally contract with us for specific projects or for specific periods of time, we may lose
these customers from year to year as the projects or maintenance contracts are completed. The loss of business from any one of
these customers could have a material adverse effect on our business or results of operations.

The execution of our growth strategy is dependent upon the continued availability of third-party financing
arrangements for our customers.

Tighter credit markets could adversely affect our customers’ ability to secure the financing necessary to proceed or
continue with pipe or other infrastructure installation, rehabilitation, strengthening, coating and cathodic protection projects.
Our customers’ or potential customers’ inability to secure financing for projects could result in the delay, cancellation or
downsizing of new projects or the suspension of projects already under contract, which could cause a decline in the demand for
our services and negatively impact our revenues and earnings.

A substantial portion of our raw materials is from a limited number of vendors, and we are subject to market
fluctuations in the prices of certain commodities.

The primary products and raw materials used by our Corrpro operations include zinc, aluminum, magnesium and other
metallic anodes, as well as wire and cable. We believe that Corrpro has multiple sources available for these raw materials and
is not dependent on any single vendor to meet its supply needs. However, the prices of these raw materials have historically
been affected by the prices of energy, petroleum, steel and other commodities, tariffs and duties on imported materials and
foreign currency and exchange rates. A significant increase in the prices of these raw materials could adversely affect our
results of operations.

We purchase the majority of our fiber requirements for Insituform® tube manufacturing from two sources. We believe,
however, that alternate sources are readily available, and we continue to negotiate with other supply sources. The manufacture
of the Insituform® tubes used in our water and wastewater pipeline rehabilitation business is dependent upon the availability of
resin, a petroleum-based product. We currently have qualified seven resin suppliers from which we intend to purchase the
majority of our resin requirements for our North American operations. For our European operations, we currently have
qualified six resin suppliers, and we currently have qualified six resin suppliers for our Asia-Pacific operations. We believe that
these and other sources of resin supply are readily available. Historically, resin prices have fluctuated on the basis of the
prevailing prices of its inputs, including styrene and oil. We anticipate that prices will continue to be heavily influenced by the
events affecting these inputs, including the oil market. If there is a shortage or contraction of fiber or resin suppliers or if the
price of fiber or resin increase, it could have an adverse effect on our results of operations.

The primary products and raw materials used in the manufacture of our FRP composite systems are carbon, glass, resins,
fabric and epoxy raw materials. Carbon and epoxies are the largest materials purchased, which are currently purchased through
a select group of suppliers, although we believe these and the other materials are available from a number of vendors. The
price of epoxy historically is affected by the price of oil. In addition, a number of factors such as worldwide demand, labor
costs, energy costs, import duties and other trade restrictions may influence the price of these raw materials. An increase in the
price of these raw materials may have an adverse effect on our operations. Further, because we utilize a limited number of
extruders to manufacture our Fusible PVC® pipe products, we could be adversely affected if one or more of these extruders is
unable to continue to manufacture our Fusible PVC® pipe products.

We also purchase a significant volume of fuel to operate our trucks and equipment. At present, we do not engage in any

type of hedging activities to mitigate the risks of fluctuating market prices for oil or fuel. A significant increase in the price of
oil could cause an adverse effect on our cost structure that we may not be able to recover from our customers.

We may become involved in legal proceedings, which will increase our costs and, if adversely determined, could have a
material effect on our financial condition, results of operations, cash flows and liquidity.

As a result of the type of work we do, namely construction, we may become engaged in legal proceedings arising from the
operation of our business, including being named as a defendant in future actions. Such actions against us may arise out of the
normal course of performing services on project sites, and include workers’ compensation claims, personal injury claims and
contract disputes with our customers. From time to time, we may also be named as a defendant for actions involving the
violation of federal and state labor laws related to employment practices, wages and benefits. We may also be a plaintiff in
legal proceedings against customers seeking to recover wages and benefits or seeking to recover payment of contractual
amounts due to us. Further, we may make claims against customers for increased costs incurred by us resulting from, among
other things, services performed by us at the request of a customer that are in excess of original project scope that are later
disputed by the customer and customer-caused delays in our contract performance.

We maintain insurance against operating hazards in amounts that we believe are customary in our industry. However, in

some instances we are self-insured and in other instances our insurance policies include deductibles and certain coverage
exclusions, so we cannot provide assurance that we are adequately insured against all of the risks associated with the conduct of
our business. A successful claim brought against us in excess of, or outside of, our insurance coverage could have a material
adverse effect on our financial condition, results of operations, cash flows and liquidity.

Litigation, regardless of its outcome, is expensive, typically diverts the efforts of our management away from operations
for varying periods of time, and can disrupt or otherwise adversely impact our relationships with current or potential customers,
subcontractors and suppliers. Payment and claim disputes with customers may also cause us to incur increased interest costs
resulting from incurring indebtedness under our revolving line of credit or receiving less interest income resulting from fewer
funds invested due to the failure to receive payment for disputed claims and accounts.

Extreme weather conditions may adversely affect our operations.

We are likely to be impacted by weather extremes, such as excessive rain or hurricanes, tornadoes, typhoons, snow and ice

or frigid temperatures, which may cause temporary, short-term anomalies in our operational performance in certain localized
geographic regions. Our Infrastructure Solutions and Corrosion Protection segments are particularly sensitive to weather
extremes. Delays and other weather impacts could adversely affect our ability to meet project deadlines and may increase a
project’s cost and decrease its profitability.

Certain of our facilities are located in regions that may be affected by natural disasters.

We have multiple facilities in and around the U.S. Gulf Coast, including facilities near Houston, Texas, and in Florida.
These regions are subject to increased hurricane activity that can result in substantial flooding. Our Aegion Energy Services
business serves large oil and gas customers in California and is headquartered in Irvine, California. Furthermore, our
Infrastructure Solutions segment has substantial operations in California. Historically, California has been susceptible to
natural disasters, such as earthquakes, drought, floods and wildfires. Although we maintain loss insurance where necessary, a
hurricane, earthquake, wildfire or other natural disaster could result in significant damage to our facilities, destruction or
disruption of our critical business or information technology systems, recovery costs and interruption to certain of our
operations. In addition, a catastrophic event could interrupt operations of our customers and suppliers, which could result in
delays or cancellation of customer orders, the loss of customers, and impediments to the manufacture or shipment of products
or execution of projects, which could result in loss of business or an increase in expense, both of which may have a material
adverse effect on our business. In the specific case of wildfires, an accusation or ultimate determination that our operations
were the cause of a wildfire may also have a material adverse effect on our business.

The actual timing, costs and benefits of the 2017 Restructuring may differ from those currently expected, which may
reduce our operating results.

On July 28, 2017, we introduced the 2017 Restructuring and, through several additional actions during 2018, expanded the

scope of the restructuring to include many of our operations around the world. The restructuring is intended to reduce
complexity and risk in our business operations, eliminate losses from underperforming businesses and also significantly reduce
our consolidated annual operating expenses. We completed much of the 2017 Restructuring during 2017 and 2018 and expect
to substantially complete the 2017 Restructuring during 2019. See Notes 1 and 4 to the consolidated financial statements
contained in this report for additional information and disclosures regarding our restructuring activities.

The 2017 Restructuring is subject to various risks, which could result in the actual timing, costs and benefits of the plan

differing from those currently anticipated. These risks and uncertainties include, among others, that: (i) we may not be able to
implement the 2017 Restructuring in the timeframe currently planned; (ii) our costs related to the 2017 Restructuring may be
higher than currently estimated; (iii) the expected annual expense reductions may be less than currently estimated; and (iv)
unanticipated disruptions to our operations may result in additional costs being incurred. Because of these and other factors, we
cannot predict whether we will realize the purpose and anticipated benefits of the 2017 Restructuring, and if we do not, our
business and results of operations may be adversely impacted. We also cannot provide assurance that we will not undertake
additional restructuring activities in the future.

Additionally, the 2017 Restructuring may yield unintended consequences, such as:

• actual or perceived disruption of service or reduction in service standards to customers;

•

the failure to preserve supplier relationships and distribution, sales and other important relationships and to resolve
conflicts that may arise;

• attrition beyond our intended reduction in headcount and reduced employee morale, which may cause our employees

who were not affected by the 2017 Restructuring to seek alternate employment;

increased risk of employment litigation; and

•
• diversion of management attention from ongoing business activities.

Divestitures and discontinued operations could negatively impact our business, and retained liabilities from businesses
that we sell could adversely affect our financial results.

As part of our portfolio management process, we review our operations for businesses, which may no longer be aligned

with our strategic initiatives and long-term objectives. For example, as part of our 2017 Restructuring discussed above in

“Strategic Initiative and Key Divestitures”, we have recently or are in the process of divesting or otherwise exiting multiple
businesses. We also continue to review our portfolio and may pursue additional divestitures. Divestitures pose risks and
challenges that could negatively impact our business, including required separation or carve-out activities and costs, disputes
with buyers or potential impairment charges. We may also dispose of a business at a price or on terms that are less than we had
previously anticipated. After reaching an agreement with a buyer for the disposition of a business, we are also subject to the
satisfaction of pre-closing conditions, as well as necessary contractual counter-party, regulatory and governmental approvals or
consents on acceptable terms, which may prevent us from completing a transaction. Dispositions may also involve continued
financial involvement, as we may be required to retain responsibility for, or agree to indemnify buyers against contingent
liabilities related to a business sold, such as lawsuits, tax liabilities, lease payments, product liability claims or environmental
matters. Under these types of arrangements, performance by the divested businesses or other conditions outside of our control
could affect future financial results.

If we do not realize the expected benefits or synergies of any divestiture transaction, our consolidated financial position,
results of operations and cash flows could be negatively impacted. Any divestiture may result in a dilutive impact to our future
earnings if we are unable to offset the dilutive impact from the loss of revenue associated with the divestiture, as well as
significant write-offs, including those related to goodwill and other intangible assets, which could have a material adverse
effect on our results of operations and financial condition.

We may from time to time undertake internal reorganizations that may adversely impact our business and results of
operations.

From time to time, including in 2019, in an effort to simplify our organizational structure and streamline our operations or

for other operational reasons, we may undertake certain internal reorganizations that may involve, among other things, the
combination or dissolution of certain of our existing subsidiaries, the creation of new subsidiaries and business divisions and
the settlement of historical inter-company transactions. Additionally, as a result of the enactment of the TCJA and its effect on
the taxation of offshore earnings, in connection with these actions or our operations generally, we may determine to repatriate
certain earnings from our international subsidiaries, which earnings were previously permanently reinvested in such
subsidiaries’ operations. In undertaking such actions, we consider, among other things, the alignment of our corporate structure
with our organizational objectives, the operational and tax efficiency of our corporate structure and the long-term cash flow
needs of our business. These efforts may not result in the intended or expected benefits, may result in disruptions to our
business and may cause the Company to incur additional expenses or tax liabilities. Accordingly, such actions may adversely
impact our business and results of operations.

Changes in the industries within which we operate and market conditions could lead to charges related to
discontinuances of certain of our businesses, asset impairment, workforce reductions or restructurings.

In response to changes in industry and market conditions, we may be required to strategically realign our resources and to
consider restructuring, disposing of or otherwise exiting businesses. Any resource realignment, or decision to limit investment
in or dispose of or otherwise exit businesses, may result in the recording of special charges, such as asset write-offs, workforce
reductions, restructuring costs or charges relating to consolidation of excess facilities or businesses. Our estimates with respect
to the useful life or ultimate recoverability of our carrying basis of assets, including purchased intangible assets, could change
as a result of such assessments and decisions. Further, our estimates relating to the liabilities for excess facilities are affected
by changes in real estate market conditions.

We may incur impairments to goodwill or long-lived assets.

We review our long-lived assets, including goodwill and other intangible assets, for impairment annually or whenever
events or changes in circumstances indicate that the carrying amount of these assets may not be recoverable. The valuation of
goodwill and other intangible assets requires assumptions and estimates of many critical factors, including revenue and market
growth, operating cash flows, market multiples and discount rates. Negative industry or economic trends, including reduced
market prices of our common stock, reduced estimates of future cash flows, disruptions to our business, slower growth rates, or
lack of growth in our relevant businesses, could lead to further impairment charges against our long-lived assets, including
goodwill and other intangible assets. If, in any period, our stock price decreases to the point where our fair value, as
determined by our market capitalization, is less than the book value of our assets for an extended period of time, this could also
indicate a potential impairment, and we may be required to record an impairment charge in that period, which could adversely
affect our results of operations.

We may be subject to information technology system failures, network disruptions, cybersecurity attacks and breaches
in data security, which could disrupt our operations and could result in a loss of assets.

In the ordinary course of our business, we collect and store sensitive data, including intellectual property, proprietary
business information, and personally identifiable information of our customers, suppliers, employees and other individuals. In
storing and managing this information, we rely upon multiple information technology systems and networks, some of which are

web-based or managed by third parties, to process, transmit and store electronic information and to manage or support a variety
of critical business processes and activities. The secure and consistent operation of these systems, networks and processes is
critical to our business operations. Our systems and networks have been, and will continue to be, the target of cybersecurity
threats, such as botnets, distributed denial-of-service attacks, malware, ransomware, phishing, viruses, spoofing and other
cyber-security incidents that could result in the unauthorized release, gathering, monitoring, use, loss or destruction of our
customers’, suppliers’ or employees’ sensitive and personal data. Successful cyber-attacks or other data breaches, as well as
risks associated with compliance with applicable data privacy laws, could harm our reputation, divert management attention
and resources, increase our operating expenses due to the employment of consultants and third party experts and the purchase
of additional infrastructure, and/or subject us to legal or regulatory liability, resulting in increased costs and loss of revenue.

While we proactively safeguard our data and are continuously enhancing our security software and controls, the increase in

frequency and sophistication of cyber-attacks may result in our security controls and practices and business continuity plans
being ineffective in anticipating, preventing and effectively responding to all potential cyber-risk exposures. Further, data
privacy is subject to frequently changing rules and regulations, which are not uniform and may possibly conflict in jurisdictions
and countries where we provide services. Our failure to adhere to or successfully implement processes in response to changing
regulatory requirements in this area could result in legal liability or impairment to our reputation in the marketplace.

Additionally, our employees and certain of our third-party service providers may have access or exposure to sensitive
customer data and systems. The misuse or unauthorized disclosure of information could result in contractual and legal liability
for us due to the actions or inactions of our employees or vendors.

To improve the effectiveness of our operations and to interface with our customers and suppliers, we use our customers’ or

suppliers’ information technology systems to submit and process invoices and payments. The failures of these systems could
disrupt our operations by causing transaction errors, processing inefficiencies, delays or cancellation of customer orders,
impediments to the manufacture or shipment of products and other business disruptions. These events could lead to financial
losses from loss of business or an increase in expense, all of which may have a material adverse effect on our business.

Increasing regulatory focus on privacy issues and expanding laws could expose us to increased liability.

In May 2018, the European Union’s new General Data Protection Regulation replaced the existing European Union Data

Protection Directive, and has had a significant impact on how businesses can collect and process the personal data of European
Union individuals, including the requirement for business to self-report personal data breaches to the relevant supervisory
authority and, under certain circumstances, to the affected data subjects, and provide additional rights to individuals whose data
is processed. Penalties for non-compliance are also significantly higher under the new law, with the maximum fine being the
higher of €20 million or 4% of global turnover for the preceding year . More than 5% of our workforce as of December 31,
2018 was employed in the European Union. In addition, numerous proposals regarding privacy and data protection are pending
before U.S. and non-U.S. legislative and regulatory bodies. Despite our commitment to complying with applicable laws, actual
or alleged violations of these laws could result in legal claims or proceedings and regulatory penalties, which could disrupt our
business, distract our employees and negatively impact our reputation as well as our results of operations. These rules and
regulations may not be uniform and may possibly conflict in jurisdictions and countries where we conduct business. Our failure
to adhere to or successfully implement processes in response to changing regulatory requirements in this area could result in
legal liability or impairment to our reputation in the marketplace.

We are subject to a number of restrictive debt covenants under our credit facility.

In October 2015, the Company amended and restated its $650.0 million senior secured credit facility, followed by

subsequent amendments in February 2018 and December 2018, (the “amended Credit Facility”) with a syndicate of banks. Our
amended Credit Facility contains certain restrictive covenants, which restrict our ability to, among other things, incur additional
indebtedness, incur certain liens on our assets or sell assets, make investments and make other restricted payments. Our
amended Credit Facility also requires us to maintain specified financial ratios under certain conditions and satisfy financial
condition tests. Our ability to meet those financial ratios and tests and otherwise comply with our financial covenants may be
affected by the factors described in this “Risk Factors” section of this Report and other factors outside our control, and we may
not be able to continue to meet those ratios, tests and covenants. Our ability to generate sufficient cash from operations to meet
our debt obligations will depend upon our future operating performance, which will be affected by general economic, financial,
competitive, business and other factors beyond our control. A breach of any of these covenants, ratios, tests or restrictions, as
applicable, or any inability to pay interest on, or principal of, our outstanding debt as it becomes due could result in an event of
default. Upon an event of default, if not waived by our lenders, our lenders may declare all amounts outstanding as due and
payable.

At December 31, 2018, we were in compliance with all of our debt covenants as required under the amended Credit

Facility. If we are unable to comply with the restrictive covenants in the future, we would be required to obtain amendments or
waivers from our lenders or secure another source of financing. If our current lenders accelerate the maturity of our
indebtedness, we may not have sufficient capital available at that time to pay the amounts due to our lenders on a timely basis.

In addition, these restrictive covenants may prevent us from engaging in transactions that benefit us, including responding to
changing business and economic conditions and taking advantage of attractive business opportunities.

We occasionally access the financial markets to finance a portion of our working capital requirements and support our
liquidity needs. Our ability to access these markets may be adversely affected by factors beyond our control and could
negatively impact our ability to finance our operations, meet certain obligations or implement our operating strategy.

We occasionally borrow under our existing credit facility to fund operations, including working capital investments.
Market disruptions such as those experienced in the United States and abroad in the past few years have materially impacted
liquidity in the credit and debt markets, making financing terms for borrowers less attractive and, in certain cases, resulting in
the unavailability of certain types of financing. Uncertainty in the financial markets may negatively impact our ability to access
additional financing or to refinance our existing credit facility or existing debt arrangements on favorable terms or at all, which
could negatively affect our ability to fund current and future expansion as well as future acquisitions and development. These
disruptions may include turmoil in the financial services industry, volatility in the markets where our outstanding securities
trade and general economic downturns in the areas where we do business. If we are unable to access funds at competitive rates,
or if our short-term or long-term borrowing costs increase, our ability to finance our operations, meet our short-term obligations
and implement our operating strategy could be adversely affected.

As a holding company, Aegion depends on its operating subsidiaries to meet its financial obligations.

Aegion Corporation is a holding company with no significant operating assets. Our subsidiaries conduct all of our
operations and own substantially all of our assets. Our cash flow and our ability to meet our obligations depends on the cash
flow of our subsidiaries. In addition, the payments of funds in the form of dividends, intercompany payments, tax sharing
payments and other forms may be subject to restrictions under the laws of the states and countries in which we operate.

The market price of our common stock is highly volatile and may result in investors selling shares of our common stock
at a loss.

The trading price of our common stock is highly volatile and subject to wide fluctuations in price in response to various

factors, many of which are beyond our control, including:

• actual or anticipated variations in quarterly operating results;

• changes in financial estimates by securities analysts that cover our stock or our failure to meet these estimates;

• conditions or trends in the U.S. wastewater rehabilitation market;

• conditions or trends in mined materials, oil and natural gas markets;

• changes in municipal and corporate spending practices;

• a downturn of the municipal bond market or lending markets generally;

• changes in the federal or state governments that impact regulation and spending regarding energy and infrastructure;

• changes in market valuations of other companies operating in our industries;

• announcements by us or our competitors of a significant acquisition or divestiture; and

• additions or departures of key personnel.

In addition, the stock market in general and The Nasdaq Global Select Market in particular have experienced extreme price

and volume fluctuations that may be unrelated or disproportionate to the operating performance of listed companies. Industry
factors may seriously harm the market price of our common stock, regardless of our operating performance. Such stock price
volatility could result in investors selling shares of our common stock at a loss.

Future sales of our common stock or equity-linked securities in the public market could adversely affect the trading
price of our common stock and our ability to raise funds in new stock offerings.

Sales of substantial numbers of additional shares of our common stock or any shares of our preferred stock, including sales
of shares in connection with any future acquisitions, or the perception that such sales could occur, may have a harmful effect on
prevailing market prices for our common stock and our ability to raise additional capital in the financial markets at a time and
price favorable to us. We may issue equity securities in the future for a number of reasons, including to finance our operations
and business strategy, to adjust our ratio of debt to equity, to satisfy obligations upon exercise of outstanding warrants or
options or for other reasons. Our certificate of incorporation provides that we have authority to issue 125,000,000 shares of
common stock. As of December 31, 2018, 31,922,409 shares of common stock were issued and outstanding.

Provisions in our certificate of incorporation could make it more difficult for a third party to acquire us or could
adversely affect the rights of holders of our common stock or the market price of our common stock.

Our certificate of incorporation provides that our board of directors has the authority, without any action of our

stockholders, to issue up to 2,000,000 shares of preferred stock. Preferred stock may be issued upon such terms and with such
28

designations as our board of directors may fix in its discretion, including with respect to: (i) the payment of dividends upon our
liquidation, dissolution or winding up; (ii) voting rights that dilute the voting power of our common stock; (iii) dividend rates;
(iv) redemption or conversion rights; (v) liquidation preferences; or (vi) voting rights.

In addition, our certificate of incorporation provides that subject to the rights of the holders of any class or series of
preferred stock set forth in our certificate of incorporation, the certificate of designation relating to such class or series of
preferred stock, or as otherwise required by law, any stockholder action may be taken only at a meeting of stockholders and
may not be effected by any written consent by such stockholders. The affirmative vote of the holders of at least 80% of the
capital stock entitled to vote for the election of directors is required to amend, repeal or adopt any provision inconsistent with
such arrangement.

These provisions could potentially be used to discourage attempts by others to obtain control of our company through
merger, tender offer, proxy, consent or otherwise by making such attempts more difficult or more costly, even if the offer may
be considered beneficial by our stockholders. These provisions also may make it more difficult for stockholders to take action
opposed by our board of directors or otherwise adversely affect the rights of holders of our common stock or the market price
of our common stock.

Our amended and restated by-laws designate the state courts of Delaware or, if no such state court has jurisdiction, the
federal court for the District of Delaware, as the sole and exclusive forum for certain types of claims that may be
initiated by our stockholders, which could discourage lawsuits against Aegion and Aegion’s directors and officers.

Our amended and restated by-laws provide that, unless waived by Aegion, the state courts of the State of Delaware or, if no

state court located in the State of Delaware has jurisdiction, the federal court for the District of Delaware, will be the sole and
exclusive forum for any claims brought by a stockholder (including a beneficial owner) (i) that are based upon a violation of a
duty by a current or former director, officer or stockholder in such capacity or (ii) as to which the Delaware General
Corporation Law confers jurisdiction upon the Delaware Court of Chancery. This exclusive forum provision may limit the
ability of our stockholders to bring a claim in a judicial forum that such stockholders find favorable for disputes with Aegion or
Aegion’s directors or officers, which may discourage such lawsuits against Aegion and Aegion’s directors and officers.
Alternatively, if a court outside of Delaware were to find this exclusive forum provision inapplicable to, or unenforceable in
respect of, one or more of the specified types of actions or proceedings described above, we could incur additional costs
associated with resolving such matters in other jurisdictions, which could adversely affect our business, financial condition or
results of operations.

We do not intend to pay cash dividends on our common stock in the foreseeable future.

We do not anticipate paying cash dividends on our common stock in the foreseeable future. Our present policy is to retain
earnings to provide for the operation and expansion of our business or for the repurchase of shares of our common stock. Any
payment of cash dividends will depend upon our earnings, financial condition, cash flows, financing agreements and other
factors deemed relevant by our board of directors. Furthermore, under the terms of certain debt arrangements to which we are a
party, we are subject to certain limitations on paying dividends. However, we carefully review this policy regularly and could
initiate dividends in the future depending on appropriate circumstances.

(1) In October 2017, our board of directors authorized the open market repurchase of up to $40.0 million of our common stock to be made
during 2018. That authorization was reduced to $30.0 million in 2018 in connection with an amendment to our Credit Facility. Any
shares repurchased were pursuant to one or more 10b5-1 plans. We began repurchasing shares under this program in January 2018 and
ceased on December 31, 2018 due to expiration of the program. Once repurchased, we promptly retired the shares.

(2) In connection with approval of our credit facility, our board of directors approved the purchase of up to $10.0 million of our common
stock in each calendar year in connection with our equity compensation programs for employees and directors. The number of shares
purchased includes shares surrendered to us to pay the exercise price and/or to satisfy tax withholding obligations in connection with
“net, net” exercises of employee stock options and/or the vesting of restricted stock, restricted stock units or performance units issued to
employees. During 2018, zero shares were surrendered in connection with stock swap transactions and 228,068 shares were surrendered
in connection with restricted stock unit and performance unit transactions. The deemed price paid was the closing price of our common
stock on the Nasdaq Global Select Market on the date that the restricted stock units or performance units vested. Once repurchased, we
promptly retired the shares.

(3) In December 2018, our board of directors authorized the open market repurchase of up to two million shares of our common stock
beginning January 1, 2019. Any shares repurchased will be pursuant to one or more 10b5-1 plans. The program will expire on the
earlier of the repurchase by the Company of two million shares of common stock pursuant to the program or the board of directors’
termination of the program. In December 2018, we amended our senior secured credit facility, which limits the open market repurchase
of our common stock to be made during 2019 to $32.0 million.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operation.

Executive Summary

Aegion combines innovative technologies with market leading expertise to maintain, rehabilitate and strengthen pipelines

and other infrastructure around the world. Since 1971, we have played a pioneering role in finding innovative solutions to
rehabilitate aging infrastructure, primarily pipelines in the wastewater, water, energy, mining and refining industries. We also
maintain the efficient operation of refineries and other industrial facilities and provide innovative solutions for the
strengthening of buildings, bridges and other structures. We are committed to Stronger. Safer. Infrastructure®. We believe the
depth and breadth of our products and services make us a leading provider for the world’s infrastructure rehabilitation and
protection needs.

Business Outlook

We believe a positive commercial outlook and the progress made over the last several years to simplify and position the
Company in markets with favorable scale and earnings profiles will lead to modest earnings growth in 2019, despite a projected
decline in consolidated revenues due to the lack of large project contributions during the year. Longer term, we believe our
core businesses can generate annual revenue growth in the low to mid-single digit range, which should result in low double-
digit annual earnings per share growth.

Infrastructure Solutions

One of the most attractive areas for growth is in the rehabilitation of municipal wastewater and pressure pipelines,
primarily in North America. We offer a diverse portfolio of solutions in a highly fragmented and growing market. We made
investments in 2018 to expand the use of Insituform® CIPP in several regions currently underserved by Insituform in the North
American wastewater pipeline market. Outside North America, we also have an attractive market in Asia-Pacific for large-
diameter pressure pipe strengthening, and we are continuing to pursue a strategy of growing third-party product sales around
the globe. Our objective is to maintain growth and our share in a large and mature market through a continued focus on
productivity and offering customer-driven solutions through technological differentiation.

Over the last few years, we completed a research and development effort that significantly reduced material and
installation costs for the Tyfo® system while maintaining the superior material properties and quality of the technology. We
also improved our InsituMain® CIPP technology to give customers a more robust solution. In 2019, we are focused on two key
technology initiatives to serve the pressure pipe and wastewater rehabilitation business. We are in final development and field
testing for a robotic system to mechanically and effectively seal the service connection between a CIPP pressurized water main
line to residential lines into homes. Success with this development initiative could address a weak point in current
commercially available small-diameter pressure pipe rehabilitation systems today. We also recently introduced the application
of ultraviolet light technology to cure felt CIPP tubes, which has the potential to reduce the environmental and equipment
footprint that is currently required for the curing process. Any new technology takes time to penetrate the market, but we
believe both initiatives represent long-term growth levers for the segment.

Corrosion Protection

Nearly 50 percent of Corrosion Protection’s revenues come from cathodic protection services for midstream oil and gas
pipelines in North America, an attractive and growing market that we believe justifies further investment to outpace market
growth. To that end, we continue to promote our new asset integrity management program for pipeline corrosion assessments.
This new service improves data accuracy and processing efficiency, customizes the data transfer format (including geospatial
mapping) and provides faster access to the information by customers. Corrosion Protection’s pipeline assessment services are
expected to create a multiplier effect for our other capabilities in direct pipeline assessments, engineering, cathodic protection
system installation and pipeline corrosion remediation. Our objective is to expand the relationships with our top customers,
who are the leading pipeline owners in North America, to accelerate revenue growth.

With oil prices trading in a more stable range, we have seen improved demand for our Tite Liner® lining pipeline
protection system and our field pipe coatings applications, both in our North America market as well as overseas. We are
focused on capturing additional opportunities in the Middle East, where we see a robust sales funnel over the next several years
as national energy companies look to increase production through multiple major onshore and offshore gas and oil field
development and expansion projects.

Energy Services

We expect Energy Services to continue to build on the momentum achieved in 2018. The outlook for day-to-day

downstream refinery maintenance remains robust based on long-term contracts and our position as the lead outsourced provider
of maintenance services at 14 out of the 17 refineries on the United States West Coast. We have an effort underway to expand

our services to those customers in mechanical maintenance, turnaround service, electrical and instrumentation maintenance,
scaffolding services and small capital construction activities.

Strategic Initiatives/Divestitures

2017 Restructuring

On July 28, 2017, our board of directors approved the 2017 Restructuring. As part of the 2017 Restructuring, we

announced plans to: (i) divest our pipe coating and insulation businesses in Louisiana, The Bayou Companies, LLC and Bayou
Wasco Insulation, LLC (collectively “Bayou”; (ii) exit all non-pipe related contract applications for the Tyfo® system in North
America; (iii) right-size the cathodic protection services operation in Canada and the CIPP businesses in Australia and
Denmark; and (iv) reduce corporate and other operating costs.

During 2018, our board of directors approved additional actions with respect to the 2017 Restructuring, which included the
decisions to: (i) divest the Australia and Denmark CIPP businesses; (ii) take actions to further optimize operations within North
America, including measures to reduce consolidated operating costs; and (iii) divest or otherwise exit multiple additional
international businesses, including: (a) our cathodic protection installation activities in the Middle East, including Corrpower
International Limited, our cathodic protection materials manufacturing and production joint venture in Saudi Arabia; (b) United
Pipeline de Mexico S.A. de C.V., our Tite Liner® joint venture in Mexico; (c) our Tite Liner® businesses in Brazil and
Argentina; (d) Aegion South Africa Proprietary Limited, our Tite Liner® and CIPP joint venture in the Republic of South
Africa; and (e) our CIPP contract installation operations in England.

We divested our Bayou business in August 2018 and our Denmark CIPP business in November 2018. Discussions are

Total pre-tax 2017 Restructuring and related impairment charges since inception were $139.7 million ($125.9 million post-
tax) and consisted of cash charges totaling $25.8 million and non-cash charges totaling $113.9 million. Cash charges included
employee severance, retention, extension of benefits, employment assistance programs and other restructuring costs associated
with the restructuring efforts described above. Non-cash charges included (i) $86.4 million related to goodwill and long-lived
asset impairment charges recorded in 2017 as part of exiting the non-pipe FRP contracting market in North America, and (ii)
$27.5 million related to allowances for accounts receivable, write-off of certain other current assets and long-lived assets,
inventory write-offs, impairment of definite-lived intangible assets, as well as net losses on the disposal of both domestic and
international entities. We reduced headcount by approximately 360 employees as a result of these actions.

We expect to incur additional cash and non-cash charges of $15 million to $19 million during 2019. The identified charges

are primarily focused in the international operations of both Infrastructure Solutions and Corrosion Protection, but will also
include certain charges in Energy Services to a lesser extent. We expect to reduce headcount by an additional 100 employees as
a result of these further actions.

2016 Restructuring

During 2016, we completed our 2016 Restructuring, which: (i) reduced/eliminated Energy Services’ upstream operations in
California and in the Permian Basin in Texas; (ii) reduced Corrosion Protection’s upstream exposure by divesting our interest in
Bayou Perma-Pipe Canada, Ltd. (“BPPC”), our Canadian pipe coating joint venture; (iii) right-sized Corrosion Protection to
compete more effectively; and (iv) reduced corporate and other operating costs. The 2016 Restructuring reduced consolidated
annual operating costs by approximately $17.4 million, of which approximately $1.2 million, $6.6 million and $5.6 million
related to recognized savings within Infrastructure Solutions, Corrosion Protection and Energy Services, respectively, and $4.0
million related to reduced corporate costs. Cost savings were achieved primarily through office closures and reducing
headcount by 964 employees, or 15.5% of our total workforce as of December 31, 2015.

During 2016, we recorded pre-tax charges of $16.1 million ($10.3 million post-tax), most of which were cash charges,
consisting primarily of employee severance, extension of benefits, early lease termination and other costs associated with the
restructuring efforts as described above. We do not expect to incur any future charges related to the 2016 Restructuring.

See “Financial Statements and Supplementary Data” in Item 8 of this Report for further discussion regarding our recent
strategic initiatives. See Note 4 to the consolidated financial statements contained in this Report for additional information on
the charges related to our restructuring efforts.

Divestitures – Planned and Completed

Through our restructuring efforts to exit higher-risk, low return markets and streamline our operations, we have divested,
or planned to divest, certain businesses in our Infrastructure Solutions and Corrosion Protection segments during 2018, 2017
and 2016:

i. On November 1, 2018, we sold substantially all of the fixed assets and inventory from our CIPP operations in

Denmark. In connection with the sale, we entered into a five-year exclusive tube-supply agreement whereby the
buyers will exclusively purchase our Insituform® CIPP liners. The buyers will also be entitled to use the Insituform®
trade name based on a trademark license granted for the same five-year time period.

ii. On August 31, 2018, we sold substantially all of the assets of Bayou and our ownership interest in Bayou Wasco

Insulation LLC, which collectively had been held for sale as part of the 2017 Restructuring and reflected our desire to
reduce further our exposure in the North American upstream oil and gas markets.

iii. On May 14, 2018, our board of directors approved plans to divest the assets and liabilities of our CIPP operations in
Australia. While restructuring actions in Australia led to year-over-year improvements in operating results in 2018,
an assessment of the long-term fit within Aegion’s portfolio led to the decision to divest the business. We are
currently in discussions with a third party and, if those discussions are successful, we expect to close a transaction in
the first half of 2019.

iv. In February 2016, we sold our fifty-one percent (51%) interest in BPPC to our joint venture partner, Perma-Pipe, Inc.

BPPC served as our pipe coating and insulation operation in Canada. The sale of our interest in BPPC was part of a
broader effort to reduce our exposure in the North American upstream market.

v. During the first quarter of 2019, we entered into discussions with prospective buyers regarding the sale of our

interests in Corrpower International Limited and Aegion South Africa Proprietary Limited. If the discussions are
successful, we expect to close the transactions in the first half of 2019.

See Notes 1 and 6 to the consolidated financial statements contained in this Report for additional information and

disclosures regarding our divestitures.

Results of Operations

Overview

Revenues of $1.33 billion were generated in 2018, just 1.9% shy of record revenues reported in 2017, which were
bolstered by a large deepwater project in our pipe coating and insulation operation within Corrosion Protection. Making up
much of the difference in 2018 was our Energy Services segment, which drove revenue increases of more than 15%, and strong
execution on large international coating services projects within Corrosion Protection.

Certain pockets of Corrosion Protection continued to experience upstream, and to a lesser extent midstream, market
challenges mostly in our North American coating services and industrial linings operations as a result of recent and current oil
prices. As part of our restructuring efforts to lower our exposure to the upstream market, on August 31, 2018, we completed the
divestiture of our domestic pipe coating and insulation operation in New Iberia, Louisiana. Also in 2018, we expanded our
effort to divest or otherwise exit non-performing international businesses, both within Infrastructure Solutions and Corrosion
Protection.

Infrastructure Solutions experienced lower revenues in 2018 compared to record levels in 2017 primarily due to the exit of

our structural FRP business in North America as well as lower productivity and an unfavorable mix in our CIPP business in
North America. We also experienced continued negative impacts from our CIPP business in Denmark, which we sold during
the fourth quarter of 2018. Partly offsetting these declines, Fusible PVC® sales grew significantly in 2018 as compared to
2017, driven by demand for pressure pipe offerings.

Energy Services grew revenues, primarily related to maintenance and construction activities, due to increased demand and

the successful completion of several labor transitions at refineries to comply with labor laws in California.

We benefited from a lower effective tax rate in 2018 as a result of the Tax Cuts and Jobs Act. Additionally, we had a

positive impact related to an adjustment of the transition tax liability.

Significant Events

2017 Restructuring – As part of the 2017 Restructuring, we recorded pre-tax charges of $29.5 million ($24.2 million post-

tax) and $23.7 million ($20.6 million post-tax) during 2018 and 2017, respectively. These charges include goodwill and
intangible asset impairment charges of $1.4 million and $2.2 million, respectively, in 2018 related to the exits of Denmark and

our cathodic protection activities in the Middle East, but exclude long-lived asset impairment charges of $86.4 million in 2017
for the Fyfe reporting unit noted below (see Notes 1 and 4 to the consolidated financial statements contained in this Report).

2016 Restructuring – As part of the 2016 Restructuring, we recorded pre-tax charges of $16.1 million ($10.3 million post-

tax) during 2016 (see Note 4 to the consolidated financial statements contained in this Report).

Acquisition and Divestiture Expenses – We recorded pre-tax expenses of $7.0 million ($5.2 million post-tax), $3.1
million ($2.0 million post-tax) and $2.7 million ($1.9 million post-tax) during 2018, 2017 and 2016, respectively, related to the
our acquisition and divestiture activity.

Divestiture – The sale of our pipe coating and insulation businesses in Louisiana resulted in a pre-tax loss of $7.0 million

($5.2 million post-tax) during 2018, which is included in “Other expense” in the Consolidated Statements of Operations (see
Notes 1 and 6 to the consolidated financial statements contained in this Report).

Impairment of goodwill – We recorded pre-tax, non-cash goodwill impairment charges of $45.4 million ($42.2 million
post-tax) during 2017. As part of the 2017 Restructuring, we exited all non-pipe related contract applications for the Tyfo®
system in North America, permanently lowering the expected future cash flows of the reporting unit. As a result of this action,
we evaluated the goodwill of our Fyfe reporting unit and determined that a triggering event occurred. The Fyfe reporting unit
is included in the Infrastructure Solutions reportable segment (see Note 2 to the consolidated financial statements contained in
this Report).

Impairment of long-lived assets – During 2017, we recorded pre-tax, non-cash long-lived asset impairment charges of
$41.0 million ($36.4 million post-tax) related to the Fyfe reporting unit (see Note 2 to the consolidated financial statements
contained in this Report). In the third quarter of 2017, as part of our 2017 Restructuring, we determined that the carrying value
of the Fyfe North America asset group exceeded the fair value, which caused us to evaluate the long-lived assets of the asset
group. Based on the results of the valuation, the carrying amount of certain long-lived assets at the Fyfe North America asset
group, such as customer relationships, trademarks and patents, exceeded their fair value.

Legal settlement – In 2016, we settled two lawsuits related to the 2012 departure of several key leaders in sales and
operations for the Tyfo® technology, which is part of the Infrastructure Solutions reportable segment. Under the settlement, we
will receive $6.6 million, which was recorded as “Gain on litigation settlement” in the Consolidated Statement of Operations.
The initial $3.6 million cash payment was received in December 2016 and the remainder is to be paid in $750,000 annual
installments over a four-year period. Payments were received for 2017 and 2018.

2018 Compared to 2017

Revenues

Revenues decreased $25.5 million, or 1.9%, to $1,333.6 million in 2018 compared to record revenues of $1,359.0 million

in 2017. The decrease in revenues was due to a $62.4 million decrease in Corrosion Protection, driven by a $90.8 million
decrease in revenues at our pipe coating and insulation operation, which completed a large deepwater project in 2017 and was
sold during the third quarter of 2018. Also contributing to the decrease was an $8.0 million decrease in Infrastructure Solutions
primarily as a result of lower CIPP contracting installation services activities in our North American and European operations.
Partially offsetting these decreases was a $45.0 million increase in Energy Services mainly due to an increase in construction
services activities and the successful completion of labor transitions at refineries to comply with labor laws in California.

Gross Profit and Gross Profit Margin

Gross profit decreased $17.9 million, or 6.3%, to $266.9 million in 2018 compared to $284.8 million in 2017. Included in

gross profit are the following items: (i) restructuring charges of $1.9 million and $0.2 million in 2018 and 2017, respectively,
related primarily to inventory write offs; and (ii) non-cash charges of $2.8 million in 2018 related to estimates for inventory
obsolescence in our cathodic protection operations. Excluding these charges, gross profit decreased $13.4 million, or 4.7%, to
$271.6 million in 2018 compared to $285.0 million in 2017. The decrease in gross profit was primarily due to: (i) a $15.3
million decrease in Corrosion Protection driven by a decrease in margins from our pipe coating and insulation operation, which
completed a large offshore project in 2017 and was sold during the third quarter of 2018, partially offset by improved project
performance in our U.S. cathodic protection operation and Middle East coating services operation; and (ii) a decrease of $8.4
million in Infrastructure Solutions primarily due to lower gross profit generated from CIPP contracting installation services
activity in our North American operation and project performance issues in our European CIPP operations, most notably in
Denmark and the Netherlands. Offsetting the decreases was a $5.8 million increase in Energy Services generated primarily
from increased revenues and activity from maintenance and construction services.

Gross profit margin declined 100 basis points to 20.0% in 2018 compared to 21.0% in 2017. Excluding restructuring
charges and the inventory obsolescence charge, gross profit margin decreased 60 basis points to 20.4% in 2018 compared to
21.0% in 2017. The decline was primarily due to a decrease in margins driven by our pipe coating and insulation operation in
Corrosion Protection, and certain isolated project execution issues related to CIPP contracting installation services activity in
our European and North American operations in Infrastructure Solutions. Offsetting the decreases was improved gross profit
margin performance in Corrosion Protection, primarily related to improved project performance in our U.S. cathodic protection
operation and high-margin project activities in our coating services operation, most notably in the Middle East.

Operating Expenses

Operating expenses decreased $6.4 million, or 2.8%, to $219.8 million in 2018 compared to $226.2 million in 2017.
Included within operating expenses are restructuring charges totaling $13.2 million and $11.0 million in 2018 and 2017,
respectively. Excluding these charges, operating expenses decreased $8.5 million, or 4.0%, to $206.6 million in 2018
compared to $215.2 million in 2017. The decrease in operating expenses was primarily due to: (i) a $5.7 million decrease in
Infrastructure Solutions primarily from exiting contracting installation services for non-pressure pipe FRP applications in our
North American operation and cost savings in connection with our 2017 Restructuring actions; (ii) a $6.6 million decrease in
Corrosion Protection mainly due to cost savings achieved in connection with our 2017 Restructuring actions, the sale of Bayou
in the third quarter of 2018, and lower incentive compensation expense. Partially offsetting the decrease in operating expenses
was a $3.8 million increase in Energy Services primarily due to an increase in general and administrative expenses to support
continued growth in the business and additional costs necessary to support the transition of our refinery personnel to the trade
unions. Additionally, we recorded a reserve reversal for certain Brinderson pre-acquisition matters in 2017 that lessened the
year-over-year decrease

Operating expenses as a percentage of revenues were 16.5% and 16.6% in 2018 and 2017, respectively. Excluding
restructuring charges, operating expenses as a percentage of revenues were 15.5% and 15.8% in 2018 and 2017, respectively.

Consolidated Net Income (Loss)

Consolidated net income (loss) improved $72.3 million, or 104.2%, to consolidated net income of $2.9 million in 2018,
from a consolidated net loss of $69.4 million in 2017. Included in consolidated net income (loss) were the following pre-tax
items: (i) goodwill impairment charges of $1.4 million and $45.4 million in 2018 and 2017, respectively; (ii) definite-lived
intangible asset impairment charges of $2.2 million and $41.0 million in 2018 and 2017, respectively; (iii) restructuring charges
of $29.5 million and $24.0 million in 2018 and 2017, respectively; (iv) acquisition and divestiture expenses of $7.0 million and
$3.1 million in 2018 and 2017, respectively; (v) a $2.8 million charge related to estimates for inventory obsolescence in our

cathodic protection operations in 2018; (vi) credit facility amendment fees of $2.2 million in 2018; and (vii) a $7.0 million loss
on the sale of Bayou in 2018.

Excluding the above items, consolidated net income increased $4.7 million, or 13.7%, to $39.2 million in 2018 from $34.4
million in 2017, primarily due to lower income taxes due to lower U.S. statutory rates, lower interest expense due to lower debt
balances and reduced foreign currency transaction losses. Partially offsetting the increases in consolidated net income was
lower operating income in 2018, primarily due to decreased revenues in Corrosion Protection’s pipe coating and insulation
operation driven by production in 2017 on a large deepwater project and subsequent divestiture in 2018.

2017 Compared to 2016

Revenues

Revenues increased $137.1 million, or 11.2%, to $1,359.0 million in 2017 compared to $1,221.9 million in 2016. The
increase in revenues was due to a $54.7 million increase in Corrosion Protection, driven by a $53.5 million increase in revenues
from the substantial completion of a large deepwater project in our pipe coating and insulation operation as well as increased
international project activities in our coating services and industrial linings operations, a $41.8 million increase in Energy
Services mainly due to increased turnaround services activities and, to a lesser extent, construction and maintenance services
activities, and a $40.6 million increase in Infrastructure Solutions primarily as a result of increased CIPP contracting
installation services activities in our North American and European operations.

Gross Profit and Gross Profit Margin

Gross profit increased $30.9 million, or 12.2%, to $284.8 million in 2017 compared to $253.9 million in 2016. The

increase in gross profit was primarily due to a $25.0 million increase in Corrosion Protection largely driven by higher revenues,
as discussed above, and a $7.5 million increase in Energy Services generated mainly from increased revenues, improved project
performance and project mix. Partially offsetting the increases in gross profit was a decrease of $1.6 million in Infrastructure
Solutions primarily due to operations included in our 2017 Restructuring which experienced a decline in high-margin revenues
and lower project performance associated with FRP project activity in our North American operation and lower project
performances in CIPP contracting installation services activity in Australia and Denmark within our Asia-Pacific and European
operations, respectively. Substantially offsetting the decrease in gross profit in Infrastructure Solutions was an increase in our
North American operation primarily driven by higher CIPP revenues and an expense of $3.6 million in 2016 related to the
recognition of inventory step up expense associated with the acquisition of Underground Solutions.

Gross profit margin improved 20 basis points to 21.0% in 2017 compared to 20.8% in 2016. The improvement was

primarily due to higher gross profit margin performance in Corrosion Protection driven by higher margin projects and
improved project performance, specifically related to the large deepwater project and international project activities noted
above, and higher gross profit margin in Energy Services resulting from improved project performance, project mix and the
elimination of cost overruns on certain isolated lump sum construction projects associated with the downsizing of our upstream
operation in 2016. Partially offsetting the increases in gross profit margin was a decrease in Infrastructure Solutions primarily
due to lower project performances in CIPP contracting installation services activity in Australia and Denmark within our Asia-
Pacific and European operations, respectively, and in FRP project activity in our North American operation.

Operating Expenses

Operating expenses increased $28.3 million, or 14.3%, to $226.2 million in 2017 compared to $197.9 million in 2016.

Included within operating expenses are restructuring charges totaling $11.0 million and $6.2 million in 2017 and 2016,
respectively. Excluding these charges, operating expenses increased $23.4 million, or 12.2%, to $215.2 million in 2017
compared to $191.7 million in 2016. The increase in operating expenses was primarily due to: (i) an $8.5 million increase in
Infrastructure Solutions, mostly driven by incremental operating expense contributions from acquisitions made in 2017 and
2016 and investments made to hire professional sales and administrative staff to facilitate continued growth in our North
American operation; (ii) a $10.1 million increase in Corrosion Protection mainly due to increased incentive compensation
expense, higher bad debt reserves, gains from sales of fixed assets in 2016 and added sales and administrative support costs;
and (iii) a $4.9 million increase in Energy Services resulting from a $4.1 million decrease in reserves for certain Brinderson
pre-acquisition matters in 2016, increased incentive compensation expense and an increase in general and administrative costs
to support continued growth.

Operating expenses as a percentage of revenues were 16.6% and 16.2% in 2017 and 2016, respectively. Excluding
restructuring charges, operating expenses as a percentage of revenues were 15.8% and 15.7% in 2017 and 2016, respectively.

Consolidated Net Income (Loss)

Consolidated net income (loss) decreased $98.9 million to a consolidated net loss of $69.4 million in 2017, from
consolidated net income of $29.5 million in 2016. Included in consolidated net income (loss) were the following items: (i)

goodwill impairment charges of $45.4 million ($42.2 million post-tax) in 2017; (ii) definite-lived intangible asset impairment
charges of $41.0 million ($36.4 million post-tax) in 2017; (iii) restructuring charges of $24.0 million ($20.8 million post-tax)
and $15.9 million ($10.2 million post-tax) in 2017 and 2016, respectively; (iv) gain on a litigation settlement of $6.6 million
($4.0 million post-tax) in 2016; and (v) acquisition and divestiture expenses of $3.1 million ($2.0 million post-tax) and $2.7
million ($2.2 million post-tax) in 2017 and 2016, respectively.

Excluding the above items, consolidated net income decreased $5.8 million, or 15.3%, to $32.0 million in 2017 from $37.8
million in 2016. The decrease was due to: (i) lower gross profit primarily from performances in operations that are included in
our 2017 Restructuring within Infrastructure Solutions; (ii) an increase in consolidated operating expenses; (iii) negative
impacts from foreign currency losses; and (iv) higher tax expense primarily due to negative impacts associated with changes in
tax valuation allowances and a $2.4 million charge related to TCJA. Partially offsetting the decreases in consolidated net
income noted above were higher revenues and related gross profit in Corrosion Protection and Energy Services.

Contract Backlog

Contract backlog is our expectation of revenues to be generated from received, signed and uncompleted contracts, the
cancellation of which is not anticipated at the time of reporting. We assume these signed contracts are funded. For government
or municipal contracts, our customers generally obtain funding through local budgets or pre-approved bond financing. We have
not undertaken a process to verify funding status of these contracts and, therefore, cannot reasonably estimate what portion, if
any, of contracts in backlog have not been funded. However, we have little history of signed contracts being canceled due to
the lack of funding. Contract backlog excludes any term contract amounts for which there are not specific and determinable
work releases and projects where we have been advised that we are the low bidder, but have not formally been awarded the
contract.

The following table summarizes our consolidated backlog by segment (in millions):

(1) December 31, 2018, 2017 and 2016 included backlog from exited or to-be exited operations of $10.0 million, $29.6 million and $21.8

million, respectively.

(2) December 31, 2018, 2017 and 2016 included backlog from exited or to-be exited operations of $11.6 million, $45.7 million and $117.1

million, respectively.

(3) Total backlog for December 31, 2018, 2017 and 2016 included backlog from exited or to-be exited operations of $21.6 million, $75.3

million and $138.9 million, respectively.

Included within backlog for Energy Services are amounts that represent expected revenues to be realized under long-term
MSAs and other signed contracts. If the remaining term of these arrangements exceeds 12 months, the unrecognized revenues
attributable to such arrangements included in backlog are limited to only the next 12 months of expected revenues. Although
backlog represents only those contracts and MSAs that are considered to be firm, there can be no assurance that cancellation or
scope adjustments will not occur with respect to such contracts.

Within our Infrastructure Solutions and Corrosion Protection segments, certain contracts are performed through our

variable interest entities, in which we own a controlling portion of the entity. As of December 31, 2018, 0.6% and 17.7% of our
Infrastructure Solutions backlog and Corrosion Protection backlog, respectively, related to these variable interest entities. A
substantial majority of our contracts in these two segments are fixed price contracts with individual private businesses and
municipal and federal government entities across the world. Energy Services, however, generally enters into cost reimbursable
contracts that are based on costs incurred at agreed upon contractual rates.

In accordance with industry practice, substantially all of our contracts are subject to cancellation or termination at the

discretion of the customer. In a situation where a customer terminates a contract, we would ordinarily be entitled to receive
payment for work performed up to the date of termination and, in certain circumstances, we may be entitled to allowable
termination and cancellation costs. There were no significant cancellations in 2018.

While management uses all information available to it to determine backlog, our backlog at any given time is subject to

changes in the scope of services to be provided as well as increases or decreases in costs relating to the contracts included
therein. Accordingly, backlog is not necessarily a reliable indicator of future revenues.

Total contract backlog decreased $23.0 million, or 3.3%, to $669.4 million at December 31, 2018 from $692.4 million at

December 31, 2017. The decrease in backlog was due primarily to the sale of Bayou and exiting certain international
businesses during 2018 as a result of the 2017 Restructuring. Excluding exited and to-be exited operations, backlog at
December 31, 2018 increased $30.7 million, or 5.0%, from December 31, 2017. The increase was to due to: (i) increased
activity in the North American Corrosion Protection market; and (ii) increased market share on the West Coast of the United
States, primarily California, for our maintenance services activities in Energy Services; partially offset by work performed on
onshore and offshore gas field development contracts in the Middle East that were included in backlog at December 31, 2017.

Consolidated customer orders, net of cancellations (“New Orders”), decreased $28.5 million, or 2.1%, to $1,333.8 million

in 2018 compared to $1,362.3 million in 2017. New Orders in 2016 were $1,134.9 million.

Subject to factors discussed in Item 1A – “Risk Factors”, we estimate that approximately $613.9 million, or 91.7%, of total

backlog at December 31, 2018 will be realized as revenues in 2019.

2018 Compared to 2017

Revenues

Revenues in Infrastructure Solutions decreased $8.0 million, or 1.3%, to $604.1 million in 2018 compared to $612.2

million in 2017. The decrease in revenues was primarily driven by: (i) a decrease in CIPP contracting installation services
activity in North America as a result of an unfavorable mix of work performed (despite a 5% increase in installed CIPP liner
footage, average revenue per foot declined nearly 8% due to a higher mix of lower-value, small-diameter projects, which
negatively impacted revenues by nearly $35 million); (ii) a decrease in FRP project activity in our North American operation,
specifically associated with our exit of non-pressure pipe FRP contracting installation services activity in North America as part
of our 2017 Restructuring; and (iii) a decrease in license royalty income from a $3.9 million license settlement in 2017 in our
North American CIPP operation. Partially offsetting the decreases in revenues was an increase in Fusible PVC® project activity
and royalty income in our North American operation.

Gross Profit and Gross Profit Margin

Gross profit in Infrastructure Solutions decreased $8.4 million, or 6.0%, to $132.4 million in 2018 compared to $140.8

million in 2017. Included in gross profit are restructuring charges of $1.3 million and $0.1 million in 2018 and 2017,
respectively. Excluding restructuring charges, gross profit decreased $7.3 million, or 5.2%, to $133.7 million in 2018
compared to $141.0 million in 2017. Gross profit decreased primarily due to lower revenues, execution issues and project
write-downs related to CIPP contracting installation services activity in our North American and European operations.
Additionally, severe weather negatively impacted North American CIPP productivity during the first four months of 2018 and
an unfavorable project mix negatively impacted gross profit during the second half of 2018. Partially offsetting the decreases
in gross profit and gross profit margin was improved execution of FRP project activity in our North American operation and
CIPP project activity in our Australian operation. Additionally, gross profit and gross profit margin improvements were noted
as Fusible PVC® project activity increased in our North American operation.

Gross profit margin declined 110 basis points to 21.9% in 2018 from 23.0% in 2017. Excluding restructuring charges,
gross profit margin declined 90 basis points to 22.1% in 2018 from 23.0% in 2017. Gross profit margin declined primarily due
to the same factors impacting the changes in gross profit, as noted above.

Operating Expenses

Operating expenses in Infrastructure Solutions decreased $6.5 million, or 6.1%, to $100.3 million in 2018 compared to
$106.8 million in 2017. As part of our restructuring efforts, we recognized charges totaling $8.0 million and $8.8 million in
2018 and 2017, respectively, related to cost reduction efforts. Excluding restructuring charges, operating expenses decreased
$5.7 million, or 5.8%, to $92.3 million in 2018 compared to $98.1 million in 2017. The decrease in operating expenses was
primarily due to exiting contracting installation services for non-pressure pipe FRP applications in our North American
operation, cost savings in connection with our 2017 Restructuring actions, lower incentive compensation in our North
American operation and lower costs allocated from our corporate administrative function.

Operating expenses as a percentage of revenues were 16.6% and 17.5% in 2018 and 2017, respectively. Excluding
restructuring charges, operating expenses as a percentage of revenues were 15.3% and 16.0% in 2018 and 2017, respectively.

Operating Income (Loss) and Operating Margin

Operating income (loss) in Infrastructure Solutions increased $85.9 million, or 138.0%, to $23.7 million in 2018 compared

to a loss of $62.2 million in 2017. Operating margin improved to 3.9% in 2018 compared to (10.2)% in 2017. Included in
operating income (loss) were the following items: (i) goodwill impairment charges of $1.4 million and $45.4 million in 2018
and 2017, respectively; (ii) definite-lived intangible asset impairment charges of $0.9 million and $41.0 million in 2018 and
2017, respectively; (iii) restructuring charges of $14.6 million and $18.1 million in 2018 and 2017, respectively, primarily
related to severance, extension of benefits, employee assistance programs, wind-down and other restructuring costs; and (iv)
acquisition and divestiture related expenses of $0.8 million and $0.7 million in 2018 and 2017.

Excluding the above items, operating income decreased $1.5 million, or 3.6%, to $41.4 million in 2018 compared to $42.9

million in 2017 and operating margin declined 20 basis points to 6.8% in 2018 from 7.0% in 2017. Operating income and
operating margin deceased primarily due to: (i) severe weather that negatively impacted productivity in our North American
CIPP contracting operation during the first four months of 2018; (ii) a $3.9 million favorable license royalty settlement in 2017;
(iii) certain isolated project execution issues related to CIPP contracting installation services activity in our European and North
American operations; and (iv) increasing labor, fuel and chemical costs in our North America operation. Offsetting these
decreases were increases in operating income primarily due to higher revenues and profitability from Fusible PVC® project
activity in our North American operation and cost savings in our North American FRP operation in connection with our 2017
Restructuring actions.

2017 Compared to 2016

Revenues

Revenues in Infrastructure Solutions increased $40.6 million, or 7.1%, to $612.2 million in 2017 compared to $571.6

million in 2016. The increase in revenues was primarily driven by record CIPP revenues in our North American operation.
Revenues also improved as a result of an increase in CIPP contracting installation services activity in our European operation
and FRP project activity in our Asia-Pacific operation, both of which benefited from business acquisitions in the second and
third quarters of 2016, respectively. Partially offsetting the increases in revenues was a decrease in FRP project activity in our
North American operation, specifically associated with non-pressure pipe FRP contracting installation services activity. As part
of our 2017 Restructuring, we are exiting contracting installation services for non-pressure pipe FRP applications within the
North American market.

Gross Profit and Gross Profit Margin

Gross profit in Infrastructure Solutions decreased $1.6 million, or 1.1%, to $140.8 million in 2017 compared to $142.4

million in 2016. Gross profit decreased primarily due to operations included in our 2017 Restructuring, which experienced a
decline in high-margin revenues and lower project performance associated with FRP project activity in our North American
operation and lower project performance in CIPP contracting installation services activity in Australia and Denmark within our
Asia-Pacific and European operations, respectively. Substantially offsetting the decreases in gross profit were increases
primarily driven by higher revenues within our North American operation associated with CIPP contracting installation services
activity, royalty income from a $3.9 million license settlement and an expense of $3.6 million in 2016 related to the recognition
of inventory step-up required in the accounting for business combinations related to the Underground Solutions acquisition in
February 2016.

Gross profit margin declined 190 basis points to 23.0% in 2017 from 24.9% in 2016. Gross profit margin declined

primarily due to the same factors impacting the changes in gross profit, as noted above.

Operating Expenses

Operating expenses in Infrastructure Solutions increased $17.0 million, or 18.9%, to $106.8 million in 2017 compared to

$89.8 million in 2016. As part of our restructuring efforts, we recognized charges totaling $8.8 million and $0.3 million in
2017 and 2016, respectively, related to cost reduction efforts. Excluding restructuring charges, operating expenses increased
$8.5 million, or 9.5%, to $98.1 million in 2017 compared to $89.6 million in 2016. The increase in operating expenses was
primarily due to incremental operating expense contributions from acquisitions in the European CIPP market and the Asia-
Pacific FRP market during 2017 and 2016, as well as the operating expense contribution from the acquisition of Underground
Solutions in the first quarter of 2016. Operating expenses also increased as a result of investments in the hiring of experienced
sales and business development professionals and administrative support costs to facilitate continued growth in our North
American operation.

Operating expenses as a percentage of revenues were 17.5% and 15.7% in 2017 and 2016, respectively. Excluding
restructuring charges, operating expenses as a percentage of revenues were 16.0% and 15.7% in 2017 and 2016, respectively.

Operating Income (Loss) and Operating Margin

Operating income (loss) in Infrastructure Solutions decreased $116.1 million to a loss of $62.2 million in 2017 compared

to income of $53.9 million in 2016. Operating margin declined to (10.2)% in 2017 compared to 9.4% in 2016. Included in
operating income (loss) were the following items: (i) goodwill impairment charges of $45.4 million in 2017; (ii) definite-lived
intangible asset impairment charges of $41.0 million in 2017; (iii) restructuring charges of $18.1 million and $2.9 million in
2017 and 2016, respectively, primarily related to severance, extension of benefits, employee assistance programs, wind-down
and other restructuring costs; (iv) acquisition and divestiture related expenses of $0.7 million and $2.7 million in 2017 and
2016, respectively; (v) inventory step-up expense of $3.6 million associated with the acquisition of Underground Solutions in
2016; and (vi) gain on litigation settlement of $6.6 million related to our FRP business in North America in 2016.

Excluding the above items, operating income decreased $13.6 million, or 24.1%, to $42.9 million in 2017 compared to
$56.5 million in 2016 and operating margin declined 290 basis points to 7.0% in 2017 from 9.9% in 2016. Operating income
and operating margin deceased primarily due to poor international CIPP project performances specifically in Australia and
Denmark, declining revenues and lower project performance related to FRP project activity in our North American operation
and higher operating expenses resulting from acquisitions and growth initiatives. Partially offsetting the decreases in operating
income and operating margin were increases mainly driven by higher revenues and related gross profit from our North
American CIPP operation, as discussed above.

2018 Compared to 2017

Revenues

Revenues in Corrosion Protection decreased $62.4 million, or 13.7%, to $393.7 million in 2018 compared to $456.1
million in 2017. The decrease was primarily due to a $90.8 million decrease in revenues in our pipe coating and insulation
operation driven by production on a large deepwater project in 2017 and its subsequent divestiture in the third quarter of 2018.
Also contributing to the decrease in revenues was a decrease in project activities in our cathodic protection operation in North
America and our industrial linings operation in South America. Partially offsetting the decreases in revenues was an increase in
revenues in our coating services operation, which benefited from increased project activity in the Middle East and its field
services operation in North America.

Gross Profit and Gross Profit Margin

Gross profit in Corrosion Protection decreased $15.3 million, or 14.1%, to $93.0 million in 2018 compared to $108.2

million in 2017. Included in gross profit are the following items: (i) restructuring charges of $0.6 million in 2018 related to
write offs of other assets; and (ii) non-cash charges of $2.8 million in 2018 related to estimates for inventory obsolescence in
our cathodic protection operations. Excluding these charges, gross profit decreased $11.9 million, or 11.0%, to $96.4 million in
2018 compared to 2017. The decrease in gross profit was substantially due to our pipe coating and insulation operation related
to the reduced revenues as described above, partially offset by project activities in our Middle East coating services operation.

Gross profit margin declined 10 basis points to 23.6% in 2018 from 23.7% in 2017. Excluding restructuring charges and

the inventory obsolescence charge, gross profit margin improved 80 basis points to 24.5% in 2018 compared to 2017. The
gross profit margin improvement was driven by high-margin project activities in our coating services operation, most notably in
the Middle East, and improved project performance in our U.S. cathodic protection operation.

Operating Expenses

Operating expenses in Corrosion Protection decreased $3.9 million, or 4.3%, to $86.0 million in 2018 compared to $89.9

million in 2017. As a part of our restructuring efforts, we recognized charges of $5.0 million and $2.2 million in 2018 and
2017, respectively. Excluding these restructuring charges, operating expenses decreased $6.6 million, or 7.6%, to $81.0 million
in 2018 compared to $87.6 million in 2017. Operating expenses decreased primarily due to cost savings achieved in
connection with our 2017 Restructuring actions, as well as lower incentive compensation expense and lower costs allocated
from our corporate administrative function.

Operating expenses as a percentage of revenues were 21.8% and 19.7% in 2018 and 2017, respectively. Excluding
restructuring charges, as noted above, operating expenses as a percentage of revenues were 20.6% and 19.2% in 2018 and
2017, respectively.

Operating Income (Loss) and Operating Margin

Operating income (loss) in Corrosion Protection decreased $14.3 million, or 115.0%, to an operating loss of $1.9 million in

2018 compared to operating income of $12.4 million in 2017. Operating margin declined 320 basis points to (0.5)% in 2018
compared to 2.7% in 2017. Included in operating income (loss) were the following items: (i) restructuring charges of $8.3
million and $5.9 million in 2018 and 2017, respectively, related to employee severance, retention, extension of benefits,
employee assistance programs, early lease termination, wind-down and other restructuring costs; (ii) a $2.8 million non-cash
charge related to estimates for inventory obsolescence in 2018; and (iii) acquisition and divestiture related expenses of $6.2
million and $2.3 million in 2018 and 2017, respectively, primarily related to the sale of our pipe coating and insulation
operation.

Excluding the above items, operating income decreased $5.3 million, or 25.6%, to $15.4 million in 2018 compared to
$20.6 million in 2017 and operating margin declined 60 basis points to 3.9% in 2018 from 4.5% in 2017. The decreases in
operating income and operating margin were primarily the result of lower revenues and related gross profit in our pipe coating
and insulation operation driven by production on a large deepwater project in 2017 and its subsequent divestiture in 2018.
Partially offsetting the decreases in operating income and operating margin were increases generated from our coating service
operation in the Middle East and our U.S. cathodic protection operation, as well as reduced operating expenses as described
above.

2017 Compared to 2016

Revenues

Revenues in Corrosion Protection increased $54.7 million, or 13.6%, to $456.1 million in 2017 compared to $401.5

million in 2016. The increase was primarily due to a $46.2 million increase in revenues in our pipe coating and insulation
operation, which included revenues from the substantial completion of a large deepwater project totaling $93.6 million and
$40.1 million in 2017 and 2016, respectively. Also contributing to the increase in revenues was an increase in international
project activities, primarily in the Middle East and North America, in our coating services and industrial linings operations.
Partially offsetting the increases in revenues was a decline in revenues in our cathodic protection operation, primarily in North
America and Europe, as well as a decline in domestic revenues in our industrial linings operation.

Gross Profit and Gross Profit Margin

Gross profit in Corrosion Protection increased $25.0 million, or 30.0%, to $108.2 million in 2017 compared to $83.3
million in 2016. The increase in gross profit was substantially due to production on a large deepwater project in our pipe
coating and insulation operation and, to a lesser extent, increased gross profit in our coating services operation driven primarily
from project activities in the Middle East and in our industrial linings operation generated primarily from project activities in
several international countries. Partially offsetting the increases in gross profit was a decrease in our cathodic protection
operation resulting from project mix and isolated project performance issues in the United States and weaker oil and gas market
conditions in Canada.

Gross profit margin improved 300 basis points to 23.7% in 2017 from 20.7% in 2016 primarily due to higher margins
generated from a large deepwater project in our pipe coating and insulation operation and higher margin projects performed in
the Middle East in our coating services, industrial linings and cathodic protection operations. Partially offsetting the increases
in gross profit margin was a decline resulting from project mix and isolated project performance issues in the United States in
our cathodic protection operation.

Operating Expenses

Operating expenses in Corrosion Protection increased $11.9 million, or 15.2%, to $89.9 million in 2017 compared to $78.0

million in 2016. As a part of our restructuring efforts, we recognized charges of $2.2 million and $0.5 million in 2017 and
2016, respectively, related to the downsizing of certain midstream and upstream operations. Excluding these restructuring
charges, operating expenses increased $10.1 million, or 13.0%, to $87.6 million in 2017 compared to $77.5 million in 2016.
The increase in operating expenses was primarily due to increased incentive compensation expense, higher bad debt reserves,
gains from sales of fixed assets in 2016 and added sales and administrative support costs.

Operating expenses as a percentage of revenues were 19.7% and 19.4% in 2017 and 2016, respectively. Excluding
restructuring charges, as noted above, operating expenses as a percentage of revenues were 19.2% and 19.3% in 2017 and
2016, respectively.

Operating Income and Operating Margin

Operating income in Corrosion Protection increased $11.0 million, or 753.6%, to $12.4 million in 2017 compared to $1.5

million in 2016. Operating margin improved 230 basis points to 2.7% in 2017 compared to 0.4% in 2016. Included in
operating income were the following items: (i) restructuring charges of $5.9 million and $4.6 million in 2017 and 2016,

respectively, related to employee severance, retention, extension of benefits, employee assistance programs, early lease
termination, wind-down and other restructuring costs; and (ii) acquisition and divestiture related expenses of $2.3 million in
2017 primarily related to the planned sale of our pipe coating and insulation operation.

Excluding restructuring charges and acquisition and divestiture expenses, operating income increased $14.6 million, or
242.7%, to $20.6 million in 2017 compared to $6.0 million in 2016 and operating margin improved 300 basis points to 4.5% in
2017 from 1.5% in 2016. The increases in operating income and operating margin were substantially due to increased gross
profit and related gross profit margin contribution from a large deepwater project in our pipe coating and insulation operation
and, to a lesser extent, increased contribution from international project activities primarily in the Middle East in our coating
services operation, partially offset by a lower contribution from our cathodic protection operation and increased operating
expenses, as noted above.

2018 Compared to 2017

Revenues

Revenues in Energy Services increased $45.0 million, or 15.5%, to $335.7 million in 2018 compared to $290.7 million in

2017. The increase was primarily due to higher volume associated with construction services activity and increased
maintenance services activities. These increases were the result of increased demand from existing customers and successful
completion of several labor transitions at refineries to comply with labor laws in California.

Gross Profit and Gross Profit Margin

Gross profit in Energy Services increased $5.8 million, or 16.2%, to $41.5 million in 2018 compared to $35.7 million in
2017. The increase in gross profit was primarily due to an increase in revenues, mostly driven by maintenance and construction
services activity, and completion of labor transitions at refineries, as noted above. Gross profit margin improved 10 basis
points to 12.4% in 2018 compared to 12.3% in 2017.

Operating Expenses

Operating expenses in Energy Services increased $4.0 million, or 13.5%, to $33.5 million in 2018 compared to $29.5
million in 2017 primarily due to an increase in general and administrative expenses to support continued growth in the business
and additional costs necessary to support the transition of our refinery personnel to the trade unions, partially offset by lower
costs allocated from our corporate administrative function. Additionally, 2017 included a $1.5 million reserve reversal for
certain Brinderson pre-acquisition matters.

Operating expenses as a percentage of revenues were 10.0% and 10.1% in 2018 and 2017, respectively. Excluding
restructuring charges noted above, operating expenses as a percentage of revenues were 9.9% and 10.1% in 2018 and 2017,
respectively.

Operating Income and Operating Margin

Operating income in Energy Services increased $1.6 million, or 24.7%, to income of $7.8 million in 2018 compared to

$6.3 million in 2017. Operating margin improved 10 basis points to 2.3% in 2018 from 2.2% in 2017. Included in operating
income were restructuring charges of $0.4 million in 2018 primarily related to severance, extension of benefits, employee
assistance programs and other restructuring costs.

Excluding restructuring charges, operating income increased $2.0 million, or 31.3%, to $8.2 million in 2018 compared to

$6.3 million in 2017 and operating margin declined 20 basis points to 2.4% in 2018 compared to 2.2% in 2017. These
increases were primarily due to increased revenues and gross profit contributions from maintenance services activities as a
result of increased demand from existing customers, partially offset by decreased gross profit contributions associated with
higher-margin turnaround services activities; (ii) project performance execution issues on a large lump-sum construction
services project; and (iii) increased operating expenses from investments to support the business and a reserve reversal for
certain Brinderson pre-acquisition matters in 2017.

2017 Compared to 2016

Revenues

Revenues in Energy Services increased $41.8 million, or 16.8%, to $290.7 million in 2017 compared to $248.9 million in
2016. The increase was primarily due to turnaround services activity generated from an increase in the number of turnaround
plans performed in 2017 and the related turnaround labor volume, which more than doubled in 2017 compared to 2016. An
increase in construction and maintenance services activities also contributed to the increase in revenues. These increases in
revenues were the result of increased demand from existing customers, coupled with expanded market share from various
customers primarily on the West Coast of the United States.

Gross Profit and Gross Profit Margin

Gross profit in Energy Services increased $7.5 million, or 26.7%, to $35.7 million in 2017 compared to $28.2 million in
2016. The increase in gross profit was primarily due to improved revenues, as noted above, and improved project performance
and project mix in turnaround, construction and maintenance services activities. Also contributing to the increase in gross
profit was the elimination of cost overruns mainly from certain isolated lump sum construction projects in the first half of 2016
associated with the downsizing of our upstream operation in 2016.

Gross profit margin improved 100 basis points to 12.3% in 2017 compared to 11.3% in 2016 primarily due to improved
project performance, project mix and the elimination of cost overruns on certain isolated lump sum construction projects, as
discussed above.

Operating Expenses

Operating expenses in Energy Services decreased $0.6 million, or 1.9%, to $29.5 million in 2017 compared to $30.0

million in 2016. As part of our restructuring efforts, we recognized charges of $5.4 million in 2016 primarily related to
downsizing our upstream operation. Excluding restructuring charges, operating expenses increased $4.9 million, or 19.8%,
primarily due to a $4.1 million decrease in reserves for certain Brinderson pre-acquisition matters in 2016, increased incentive
compensation expense and an increase in general and administrative expenses to support continued growth of the business.

Operating expenses as a percentage of revenues were 10.1% and 12.1% in 2017 and 2016, respectively. Excluding
restructuring charges noted above, operating expenses as a percentage of revenues were 10.1% and 9.9% in 2017 and 2016,
respectively.

Operating Income (Loss) and Operating Margin

Operating income (loss) in Energy Services increased $10.8 million to income of $6.3 million in 2017 compared to a loss

of $4.6 million in 2016. Operating margin improved 400 basis points to 2.2% in 2017 from (1.8)% in 2016. Included in
operating income (loss) were restructuring charges of $8.2 million in 2016 primarily related to severance, retention, extension
of benefits, employee assistance programs, wind-down, early lease termination and other restructuring costs related to the
downsizing of our upstream operation.

Excluding restructuring charges, operating income increased $2.7 million, or 74.1%, to $6.3 million in 2017 compared to

$3.6 million in 2016 and operating margin improved 80 basis points to 2.2% in 2017 compared to 1.4% in 2016. These
increases were primarily due to higher revenues and related gross profit generated from increased turnaround, construction and
maintenance services activities, partially offset by an increase in operating expenses, as discussed above.

Other Income (Expense)

Interest Income and Expense

Interest income increased $0.4 million in 2018 compared to 2017 primarily due to interest received on the $8.0 million
note receivable acquired in the Bayou sale. Interest expense increased by $1.3 million to $17.3 million in 2018 compared to
$16.0 million in 2017. During 2018, we recognized expenses of $2.2 million related to certain arrangement and other fees
associated with amending our credit facility as well as the write-off of previously unamortized deferred financing costs. Both
charges were recorded to “Interest expense” in the Consolidated Statement of Operations. Excluding these charges, interest
expense decreased by $0.9 million as compared to 2017 due to reduced loan principal balances, partially offset by higher
LIBOR-based borrowing costs under our amended Credit Facility.

Interest income decreased less than $0.1 million in 2017 compared to 2016. Interest expense increased by $1.0 million to

$16.0 million in 2017 compared to $15.0 million in 2016. Interest expense increased primarily due to rising LIBOR-based
borrowing costs under our Credit Facility, partially offset by reduced outstanding loan principal balances during 2017
compared to 2016.

Other Income (Expense)

Other expense was $9.9 million in 2018, which included: (i) charges of $7.0 million related to the loss on sale of our pipe

coating and insulation businesses in Louisiana; (ii) charges of $4.0 million related to the dissolution of certain restructured
entities including the release of cumulative currency translation adjustments resulting from those disposals; and (iii) foreign
currency transaction losses. Partially offsetting the charges was income of $1.3 million related to the release of a long-term
retirement obligation.

Other expense was $2.2 million in 2017 and primarily consisted of foreign currency transaction losses. Other expense was
$0.7 million in 2016 and primarily consisted of foreign currency transaction losses, partially offset by the release of cumulative
currency translation gains related to disposed entities.

Taxes on Income (Loss)

On December 22, 2017, the U.S. government enacted the TCJA. The TCJA includes significant changes to the U.S.

corporate income tax system including: (i) a federal corporate rate reduction from 35% to 21%; (ii) limitations on the
deductibility of interest expense and executive compensation; (iii) creation of new minimum taxes such as the Global
Intangible Low Taxed Income (“GILTI”) tax and the base erosion anti-abuse tax (“BEAT”); and (iv) the transition of U.S.
international taxation from a worldwide tax system to a modified territorial tax system, which resulted in a one time U.S. tax
liability on those earnings that had not previously been repatriated to the U.S. Beginning in 2018, we no longer record U.S.
federal income tax on our share of income from foreign subsidiaries and no longer record a benefit for foreign tax credits
related to that income.

Taxes on income (loss) decreased $5.1 million to a benefit of $0.1 million in 2018 compared to $5.0 million in 2017. Our

effective tax rate was negative 4.5% and negative 8.1% in 2018 and 2017, respectively. The effective tax rate in 2018 was
positively impacted by: (i) a $1.9 million adjustment to the mandatory deemed repatriation tax on foreign earnings; and (ii) a
$1.5 million discrete item related to employee share-based awards that vested during 2018. Together, the adjustment to the
repatriation tax and the discrete item had a 114.6% benefit to the effective tax rate during 2018. Partially offsetting the benefits
were valuation allowances recorded on certain net operating losses in foreign jurisdictions for which no income tax benefit can
be recognized.

Taxes on income decreased $1.1 million to $5.0 million in 2017 compared to $6.1 million in 2016. The effective tax rate

in 2017 was unfavorably impacted by (i) charges associated with the TCJA, which resulted in additional income tax expense of
$2.4 million. The expense is primarily related to the TCJA’s transition tax on previously unremitted earnings of non-U.S.
subsidiaries offset by the release of a deferred tax liability on unremitted foreign earnings; (ii) significant pre-tax charges
primarily related to goodwill impairment, which were not deductible for tax purposes; and (iii) the impact of establishing
valuation allowances on deferred tax assets in jurisdictions where we are unlikely to recognize these benefits.

The effective tax rate in 2016 was positively impacted by: (i) a $4.2 million net benefit, or 11.8% benefit to the effective

tax rate, related to reductions of previously recorded valuation allowances in the U.S., due to changes in the realization of
future tax benefits and deferred tax composition changes; and (ii) a $2.6 million net benefit from foreign tax rate differences
primarily related to earnings from Europe. Partially offsetting these benefits was: (i) a $1.4 million increase in the valuation
allowance on certain net operating losses and deferred tax assets in foreign jurisdictions, primarily Europe; (ii) certain non-
deductible tax items related to the 2016 Restructuring; and (iii) a higher mix of earnings toward U.S. jurisdictions, which
generally have higher statutory tax rates.

Non-controlling Interests

Income and loss attributable to non-controlling interests was income of $0.2 million in 2018, income of $2.8 million in
2017 and a loss of $0.3 million in 2016. In 2018, income from our Corrosion Protection joint ventures in Oman, South Africa
and Louisiana and our Infrastructure Solutions joint ventures in Asia were partially offset by losses from our Corrosion
Protection joint venture in Mexico. In 2017, income was primarily driven from our joint venture in Louisiana, which
performed a majority of its work on a large deepwater project in our pipe coating and insulation operation.

Sources and Uses of Cash

We expect the principal operational use of funds for the foreseeable future will be for capital expenditures, working capital,

debt service and share repurchases.

During 2018, capital expenditures were primarily used to: (i) support our Infrastructure Solutions North American CIPP
business, expand our Corrosion Protection businesses in the Middle East and provide growth capital for Energy Services; and
(ii) boost our information systems platform with a new human capital management system and upgrades to our enterprise
resource planning system. For 2019, we anticipate that we will spend approximately $25.0 million to $30.0 million for capital
expenditures, which is slightly below 2018 spending levels.

In December 2018, our board of directors authorized the open market repurchase of up to two million shares of our
common stock. The program did not establish a time period in which the repurchases had to be made. That authorization is
now limited to $32.0 million in 2019 due to the December 2018 amendment to our Credit Facility. The shares are repurchased
from time to time in the open market, subject to cash availability, market conditions and other factors, and in accordance with
applicable regulatory requirements. We are not obligated to acquire any particular amount of common stock and, subject to
applicable regulatory requirements, may commence, suspend or discontinue purchases at any time without notice or
authorization. During 2018, we acquired 949,464 shares of our common stock for $20.3 million ($21.36 average price per
share) through the open market repurchase program discussed above. In addition, we repurchased 228,068 shares of our
common stock for $5.5 million ($24.07 average price per share) in connection with the satisfaction of tax obligations in
connection with the vesting of restricted stock, restricted stock units and performance units. Any shares repurchased during
2019 are expected to be funded primarily through available cash. Once repurchased, we promptly retire such shares.

As part of our 2017 Restructuring, we utilized cash of $14.8 million during 2018 and $23.3 million in cumulative cash

payments since 2017 related to employee severance, extension of benefits, employment assistance programs, early lease and
contract termination and other restructuring related costs as we exit our non-pipe related contract applications for the Tyfo®
system in North America, right-size our cathodic protection services operations in Canada and the Middle East, divest our
Infrastructure Solutions businesses in Australia and Denmark, and reduce corporate and other operating costs. Cumulatively,
we have incurred both cash and non-cash charges of $139.7 million, of which $86.4 million relates to goodwill and long-lived
asset impairment charges recorded in 2017 as part of exiting the non-pipe FRP contracting market in North America. We
expect to incur additional cash and non-cash charges of $15 million to $19 million during 2019.

As part of our 2016 Restructuring, we incurred $15.3 million in cash charges during 2016 related to employee severance,

extension of benefits, employment assistance programs and early lease termination and other restructuring costs as we
repositioned our Energy Services’ upstream operations in California, right-sized Corrosion Protection to compete more
effectively, and reduced corporate and other operating costs. We do not expect to incur any future cash costs related to the 2016
Restructuring.

At December 31, 2018, our cash balances were located worldwide for working capital and support needs. Given the

breadth of our international operations, approximately $47.2 million, or 56.5%, of our cash was denominated in currencies
other than the United States dollar as of December 31, 2018. We manage our worldwide cash requirements by reviewing
available funds among the many subsidiaries through which we conduct business and the cost effectiveness with which those
funds can be accessed. The repatriation of cash balances from certain of our subsidiaries could have adverse tax consequences
or be subject to regulatory capital requirements; however, those balances are generally available without legal restrictions to
fund ordinary business operations. As a result of the deemed mandatory repatriation provisions in the TCJA, we included
$206.7 million of undistributed earnings in income subject to U.S. tax at reduced tax rates. Certain provisions within the TCJA
effectively transition the U.S. to a territorial system and eliminates deferral on U.S. taxation for certain amounts of income that
are not taxed at a minimum level. At this time, we do not intend to distribute earnings in a taxable manner, and therefore,
intend to limit distributions to: (i) earnings previously taxed in the U.S.; (ii) earnings that would qualify for the 100 percent
dividends received deduction provided in the TCJA; or (iii) earnings that would not result in significant foreign taxes. As a
result, we did not recognize a deferred tax liability on any remaining undistributed foreign earnings at December 31, 2018.

Our primary source of cash is operating activities. We occasionally borrow under our line of credit’s available capacity to

fund operating activities, including working capital investments. Our operating activities include the collection of accounts
receivable as well as the ultimate billing and collection of contract assets. At December 31, 2018, we believed our net accounts
receivable and our contract assets, as reported on our Consolidated Balance Sheet, were fully collectible and a significant
portion of the receivables will be collected within the next twelve months. From time to time, we have net receivables recorded
that we believe will be collected but are being disputed by the customer in some manner. Disputes of this nature could
meaningfully impact the timing of receivable collection or require us to invoke our contractual or legal rights in a lawsuit or
alternative dispute resolution proceeding. If in a future period we believe any of these receivables are no longer collectible, we
would increase our allowance for bad debts through a charge to earnings.

Cash Flows from Operating Activities

Cash flows from operating activities provided $39.7 million and $63.6 million in 2018 and 2017, respectively. The
decrease in operating cash flow from 2018 to 2017 was primarily due to lower operating income during 2018 as compared to
2017, exclusive of significant non-cash charges in both periods. Additionally, cash flows during 2018 and 2017 were
negatively impacted by $14.8 million and $9.4 million, respectively, in cash payments related to our restructuring activities.
Cash flows in 2016 were negatively impacted by $15.3 million in cash payments related to our restructuring activities.

Net income recorded in 2018 was negatively impacted by non-cash charges of $24.4 million related to restructuring,
impairments and the loss on sale of Bayou. The net loss recorded in 2017 was negatively impacted by non-cash charges of
$96.5 million related to restructuring, definite-lived intangible asset impairments and goodwill impairments. Working capital
used $35.4 million of cash during 2018 compared to $10.2 million used in 2017. This increased usage was primarily attributed
to favorable customer prepayments in 2017 related to large Middle East coating projects executed in 2018.

Cash flows from operating activities provided $63.6 million and $71.2 million in 2017 and 2016, respectively. The
decrease was due to the timing of customer payments on certain large projects and an overall growth in revenues during 2017
compared to 2016. Days sales outstanding increased by approximately ten days as of December 31, 2017 compared to
December 31, 2016. However, excluding the impacts of the coating and insulation project activity at our Bayou Louisiana
facility, days sales outstanding decreased by five days year over year, primarily due to stronger collections in all of our
Corrosion Protection platform businesses and the customer prepayments related to Middle East coating projects mentioned
above.

Cash Flows from Investing Activities

Cash flows from investing activities provided $1.2 million of cash in 2018 and used $39.5 million of cash in 2017. During

2018, we received $37.9 million from the sale of Bayou and we used $9.0 million for two smaller acquisitions. During 2017,
we used approximately $8.0 million to acquire Environmental Techniques. During 2016, we used $96.3 million to acquire
Underground Solutions, Fyfe Europe, the CIPP business of LMJ and Concrete Solutions. During 2016, we received proceeds
of $6.6 million, net of cash disposed, from the sale of our interest in our Canadian pipe coating operation. We used $30.5
million in cash for capital expenditures in 2018 compared to $30.8 million in 2017 and $38.8 million in 2016. The higher
levels in 2016 were primarily due to $13.5 million in capital expenditures related to constructing the new pipe coating and
insulation plant in our Corrosion Protection segment. In 2018 and 2017, $0.9 million and $1.0 million, respectively, of non-
cash capital expenditures were included in accounts payable and accrued expenses. Capital expenditures in 2018, 2017 and
2016 were partially offset by $3.0 million, $0.7 million and $3.3 million, respectively, in proceeds received from asset
disposals.

Cash Flows from Financing Activities

Cash flows from financing activities used $60.4 million during 2018 compared to $56.4 million used in 2017. In 2018 and

2017, we used cash of $25.8 million and $37.8 million, respectively, to repurchase 1.2 million and 1.7 million shares,
respectively, of our common stock through open market purchases and in connection with our equity compensation programs as
discussed in Note 9 to the consolidated financial statements contained in this report. During 2018, we had net repayments on
the line of credit of $7.0 million, which included a $35.0 million repayment from the proceeds on the Bayou sale, net of
borrowings of $28.0 million for domestic working capital needs, and we used cash of $26.3 million to pay down the principal
balance of our term loan. During 2017, we had net borrowings of $2.0 million from our line of credit to fund domestic working
capital needs, and we used cash of $21.6 million to pay down the principal balance of our term loan. During 2016, we had net
borrowings of $36.0 million from our line of credit primarily to fund our acquisition activity, and we used cash of $17.5 million
to pay down the principal balance of our term loan. Additionally, we used cash of $44.5 million to repurchase 2.3 million
shares of our common stock.

Long-Term Debt

In October 2015, we entered into an amended and restated $650.0 million senior secured credit facility with a syndicate of
banks. In February 2018 and December 2018, we amended this facility (the “amended Credit Facility”). The amended Credit
Facility consists of a $275.0 million five-year revolving line of credit and a $308.4 million five-year term loan facility, each
with a maturity date in February 2023.

We paid expenses of $3.1 million associated with the amended Credit Facility, $1.4 million related to up-front lending fees
and $1.7 million related to third-party arranging fees and expenses, the latter of which was recorded in “Interest expense” in the
Consolidated Statement of Operations in 2018. In addition, we had $2.4 million in unamortized loan costs associated with the
original Credit Facility, of which $0.6 million was written off and recorded in “Interest expense” in the Consolidated Statement
of Operations in 2018.

Our indebtedness at December 31, 2018 consisted of $282.2 million outstanding from the $308.4 million term loan under

the amended Credit Facility, $31.0 million on the line of credit under the amended Credit Facility and $1.0 million of third-
party notes and bank debt.

As of December 31, 2018, we had $27.9 million in letters of credit issued and outstanding under the amended Credit
Facility. Of such amount, $12.3 million was collateral for the benefit of certain of our insurance carriers and $15.5 million was
for letters of credit or bank guarantees of performance or payment obligations of foreign subsidiaries.

In October 2015, we entered into an interest rate swap agreement for a notional amount of $262.5 million, which is set to
expire in October 2020. The notional amount of this swap mirrors the amortization of a $262.5 million portion of our $350.0
million term loan drawn from the original Credit Facility. The swap requires us to make a monthly fixed rate payment of
1.46% calculated on the amortizing $262.5 million notional amount, and provides us to receive a payment based upon a
variable monthly LIBOR interest rate calculated on the same amortizing $262.5 million notional amount. The receipt of the
monthly LIBOR-based payment offsets a variable monthly LIBOR-based interest cost on a corresponding $262.5 million
portion of our term loan from the original Credit Facility. This interest rate swap is used to partially hedge the interest rate risk
associated with the volatility of monthly LIBOR rate movement and is accounted for as a cash flow hedge.

In March 2018, we entered into an interest rate swap forward agreement that begins in October 2020 and expires in
February 2023 to coincide with the amortization period of the amended Credit Facility. The swap will require us to make a
monthly fixed rate payment of 2.937% calculated on the then amortizing $170.6 million notional amount, and provides us to
receive a payment based upon a variable monthly LIBOR interest rate calculated on the same amortizing $170.6 million
notional amount. The receipt of the monthly LIBOR-based payment will offset the variable monthly LIBOR-based interest
cost on a corresponding $170.6 million portion of our term loan from the amended Credit Facility. This interest rate swap will
be used to partially hedge the interest rate risk associated with the volatility of monthly LIBOR rate movement and accounted
for as a cash flow hedge.

The amended Credit Facility is subject to certain financial covenants including a consolidated financial leverage ratio and

consolidated fixed charge coverage ratio. We were in compliance with all covenants at December 31, 2018 and expect
continued compliance for the foreseeable future.

We believe that we have adequate resources and liquidity to fund future cash requirements and debt repayments with cash

generated from operations, existing cash balances and additional short- and long-term borrowing capacity for the next 12
months.

See Note 8 to the consolidated financial statements contained in this Report for additional information and disclosures

regarding our long-term debt.

Disclosure of Contractual Obligations and Commercial Commitments

We have entered into various contractual obligations and commitments in the course of our ongoing operations and
financing strategies. Contractual obligations are considered to represent known future cash payments that we are required to
make under existing contractual arrangements, such as debt and lease agreements. These obligations may result from both
general financing activities or from commercial arrangements that are directly supported by related revenue-producing
activities. Commercial commitments represent contingent obligations, which become payable only if certain pre-defined
events were to occur, such as funding financial guarantees. See Note 12 to the consolidated financial statements contained in
this Report for further discussion regarding our commitments and contingencies.

The following table provides a summary of our contractual obligations and commercial commitments as of December 31,
2018. This table includes cash obligations related to principal outstanding under existing debt agreements and operating leases

(1) Cash obligations are not discounted. See Notes 8 and 12 to the consolidated financial statements contained in this Report regarding our

long-term debt and amended Credit Facility and commitments and contingencies, respectively.

(2) Interest on long-term debt was calculated using the current annualized rate on our long-term debt as discussed in Note 8 to the

consolidated financial statements contained in this Report.

(3) Liabilities related to FASB ASC 740, Income Taxes, have not been included in the table above because we are uncertain as to if or when
such amounts may be settled. As of December 31, 2018, we had income tax receivable and income tax payable of $6.6 million and
$1.4 million, respectively, recorded on our consolidated balance sheet.
(4) There were no material purchase commitments at December 31, 2018.
(5) Amounts exclude approximately $7.0 million of cash charges expected to be incurred in 2019 related to the 2017 Restructuring.

Off-Balance Sheet Arrangements

We use various structures for the financing of operating equipment, including borrowings and operating leases. All debt is

presented in the balance sheet. Our future commitments were $430.8 million at December 31, 2018. We have no other off-
balance sheet financing arrangements or commitments. See Note 12 to the consolidated financial statements contained in this
Report regarding commitments and contingencies.

Critical Accounting Policies

Discussion and analysis of our financial condition and results of operations are based upon our consolidated financial
statements, which have been prepared in accordance with accounting principles generally accepted in the United States of
America. The preparation of these financial statements requires us to make estimates and judgments that affect the reported
amount of assets and liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities at the financial
statement dates. Actual results may differ from these estimates under different assumptions or conditions.

Some accounting policies require the application of significant judgment by management in selecting the appropriate

assumptions for calculating financial estimates. By their nature, these judgments are subject to an inherent degree of
uncertainty. We believe that our critical accounting policies are those described below. For a detailed discussion on the
application of these and other accounting policies, see Note 2 to the consolidated financial statements contained in this Report.

Revenue Recognition

On January 1, 2018, we adopted FASB ASC 606, Revenue from Contracts with Customers (“FASB ASC 606”) for all
contracts that were not completed using the modified retrospective transition method. We recognized the cumulative effect of
initially applying FASB ASC 606 as an adjustment to the opening balance of retained earnings. Prior period information has
not been restated and continues to be reported under the accounting standards in effect for those periods.

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of

account in FASB ASC 606. A contract’s transaction price is allocated to each distinct performance obligation and recognized as

revenue when, or as, the performance obligation is satisfied. For contracts in which construction, engineering and installation
services are provided, there is generally a single performance obligation as the promise to transfer the individual goods or
services is not separately identifiable from other promises in the contracts and, therefore, not distinct. The bundle of goods and
services represents the combined output for which the customer has contracted. For product sales contracts with multiple
performance obligations where each product is distinct, we allocate the contract’s transaction price to each performance
obligation using our best estimate of the standalone selling price of each distinct good in the contract. For royalty license
agreements whereby intellectual property is transferred to the customer, there is a single performance obligation as the license
is not separately identifiable from the other goods and services in the contract.

Our performance obligations are satisfied over time as work progresses or at a point in time. Revenues from construction,

engineering and installation services are recognized over time using an input measure (e.g., costs incurred to date relative to
total estimated costs at completion) to measure progress toward satisfying performance obligations. Incurred cost represents
work performed, which corresponds with, and thereby best depicts, the transfer of control to the customer. Contract costs
include labor, material, overhead and, when appropriate, general and administrative expenses. Revenues from maintenance
contracts are structured such that we have the right to consideration from a customer in an amount that corresponds directly
with the performance completed to date. Therefore, we utilize the practical expedient in FASB ASC 606-55-255, which allows
us to recognize revenue in the amount to which we have the right to invoice. Revenues from royalty license arrangements are
recognized either at contract inception when the license is transferred or when the royalty has been earned, depending on
whether the contract contains fixed consideration. Revenues from stand-alone product sales are recognized at a point in time,
when control of the product is transferred to the customer.

Accounting for long-term contracts involves the use of various techniques to estimate total contract revenue and costs. For

long-term contracts, we estimate the profit on a contract as the difference between the total estimated revenue and expected
costs to complete a contract, and recognizes that profit over the life of the contract. Contract estimates are based on various
assumptions to project the outcome of future events that sometimes span multiple years. These assumptions include labor
productivity and availability; the complexity of the work to be performed; the cost and availability of materials; the
performance of subcontractors; and the availability and timing of funding from the customer.

Our contracts do not typically contain variable consideration or other provisions that increase or decrease the transaction
price. In rare situations where the transaction price is not fixed, we estimate variable consideration at the most likely amount to
which we expect to be entitled. We include estimated amounts in the transaction price to the extent it is probable that a
significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable
consideration is resolved. For royalty license agreements, we apply the sales-based and usage-based royalty exception and
recognize royalties at the later of: (i) when the subsequent sale or usage occurs; or (ii) the satisfaction or partial satisfaction of
the performance obligation to which some or all of the sales-or usage-based royalty has been allocated. For contracts in which
a portion of the transaction price is retained and paid after the good or service has been transferred to the customer, we do not
recognize a significant financing component. The primary purpose of the retainage payment is often to provide the customer
with assurance that we will perform our obligations under the contract, rather than to provide financing to the customer.

Our estimates of variable consideration and determination of whether to include estimated amounts in the transaction price

are based largely on an assessment of anticipated performance and all information (historical, current and forecasted) that is
reasonably available.

Taxation

We provide for estimated income taxes payable or refundable on current year income tax returns, as well as the estimated

future tax effects attributable to temporary differences and carryforwards, in accordance with FASB ASC 740, Income Taxes
(“FASB ASC 740”). FASB ASC 740 also requires that a valuation allowance be recorded against any deferred tax assets that
are not likely to be realized in the future. The determination is based on our ability to generate future taxable income and, at
times, is dependent on our ability to implement strategic tax initiatives to ensure full utilization of recorded deferred tax assets.
Should we not be able to implement the necessary tax strategies, we may need to record valuation allowances for certain
deferred tax assets, including those related to foreign income tax benefits. Significant management judgment is required in
determining the provision for income taxes, deferred tax assets and liabilities and any valuation allowances recorded against net
deferred tax assets.

As a result of the TCJA’s reduction in the U.S. corporate income tax rate from 35% to 21%, FASB ASC 740 required us to
remeasure our deferred tax assets and liabilities based on tax rates at which the balances are expected to reverse in the future.
The provisional amount recorded for the remeasurement of our deferred tax balances resulted in no adjustment to tax expense.
The remeasurement of the deferred tax assets gave rise to an additional income tax expense of $5.1 million in 2017, which was
offset by an equal reduction in the valuation allowance of $5.1 million.

In accordance with FASB ASC 740, tax benefits from an uncertain tax position may be recognized when it is more likely

than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation

processes, based on the technical merits. In addition, this recognition model includes a measurement attribute that measures the
position as the largest amount of tax that is greater than 50% likely of being realized upon ultimate settlement in accordance
with FASB ASC 740. This interpretation also provides guidance on derecognition, classification, interest and penalties,
accounting in interim periods, disclosure and transition.

We recognize tax liabilities in accordance with FASB ASC 740 and we adjust these liabilities when our judgment changes
as a result of the evaluation of new information not previously available. Due to the complexity of some of these uncertainties,
the ultimate resolution may result in a payment that is materially different from our current estimate of the tax liabilities. These
differences will be reflected as increases or decreases to income tax expense in the period in which they are determined. While
we believe the resulting tax balances as of December 31, 2018 and 2017 were appropriately accounted for in accordance with
FASB ASC 740, the ultimate outcome of such matters could result in favorable or unfavorable adjustments to our consolidated
financial statements and such adjustments could be material.

In 2017, in connection with our initial analysis of the TCJA, we recorded a provisional estimated net income tax expense
of $2.4 million by applying the guidance under Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the
Tax Cuts and Jobs Act (“SAB 118”). In accordance with SAB 118, the estimated income tax represented our best estimate at
the time it was made, but also understanding that the provisional amount was subject to further adjustments under SAB 118.
During 2018, we finalized our calculations of the transition tax liability under the TCJA and adjusted the liability downward by
$1.9 million primarily due to further refinement of computations related to earnings and profits, cash and cash equivalents, state
income tax and foreign withholding taxes pursuant to guidance issued during the year. This adjustment was recorded as a
reduction to income tax expense in 2018.

Purchase Price Accounting

We account for our acquisitions in accordance with FASB ASC 805, Business Combinations. The base cash purchase price

plus the estimated fair value of any non-cash or contingent consideration given for an acquired business is allocated to the
assets acquired (including identified intangible assets) and liabilities assumed based on the estimated fair values of such assets
and liabilities. The excess of the total consideration over the aggregate net fair values assigned is recorded as goodwill.
Contingent consideration, if any, is recognized as a liability as of the acquisition date with subsequent adjustments recorded in
the consolidated statements of operations. Indirect and general expenses related to business combinations are expensed as
incurred.

We typically determine the fair value of tangible and intangible assets acquired in a business combination using

independent valuations that rely on management’s estimates of inputs and assumptions that a market participant would use.
Key assumptions include cash flow projections, growth rates, asset lives, and discount rates based on an analysis of weighted
average cost of capital.

Long-Lived Assets

Property, plant and equipment and other identified intangibles (primarily customer relationships, patents and acquired

technologies, trademarks, licenses and non-compete agreements) are recorded at cost, net of accumulated depreciation,
amortization and impairment, and, except for goodwill, are depreciated or amortized on a straight-line basis over their
estimated useful lives. Changes in circumstances such as technological advances, changes to our business model or changes in
our capital strategy can result in the actual useful lives differing from our estimates. During 2018, no such changes were noted.
If we determine that the useful life of our property, plant and equipment or our identified intangible assets should be shortened,
we would depreciate or amortize the net book value in excess of the salvage value over its revised remaining useful life,
thereby increasing depreciation or amortization expense.

Long-lived assets, including property, plant and equipment and other intangibles, are reviewed for impairment whenever

events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Such impairment
tests are based on a comparison of undiscounted cash flows to the recorded value of the asset. The estimate of cash flow is
based upon, among other things, assumptions about expected future operating performance. Our estimates of undiscounted
cash flow may differ from actual cash flow due to, among other things, technological changes, economic conditions, changes to
our business model or changes in our operating performance. If the sum of the undiscounted cash flows is less than the
carrying value, we recognize an impairment loss, measured as the amount by which the carrying value exceeds the fair value of
the asset.

Impairment Review – 2017

As part of the 2017 Restructuring, which was approved by our board of directors on July 28, 2017, we exited all non-pipe

related contract applications for the Tyfo® system in North America. As a result of this action, we evaluated the long-lived
assets of our Fyfe reporting unit, which caused us to review the financial performance of at-risk asset groups within that
reporting unit in accordance with FASB ASC 360, Property, Plant and Equipment (“FASB ASC 360”). The results of the Fyfe
reporting unit and its related asset groups are reported within the Infrastructure Solutions reportable segment.

The assets of an asset group represent the lowest level for which identifiable cash flows can be determined independent of

other groups of assets and liabilities. The Fyfe North America asset group was the only at-risk asset group reviewed for
impairment. We developed internal forward business plans under the guidance of local and regional leadership to determine the
undiscounted expected future cash flows derived from Fyfe North America’s long-lived assets. Such were based on
management’s best estimates considering the likelihood of various outcomes. Based on the internal projections, we determined
that the sum of the undiscounted expected future cash flows for the Fyfe North America asset group was less than the carrying
value of the assets, and as a result, engaged a third-party valuation firm to assist management in determining the fair value of
long-lived assets for the Fyfe North America asset group.

In order to determine the impairment amount of long-lived assets, we first determined the fair value of each key
component of our long-lived assets for the Fyfe North America asset group. The fair values were derived using various
income-based approaches, which utilize discounted cash flows to evaluate the net earnings attributable to the asset being
measured. Key assumptions used in assessment include the discount rate (based on weighted-average cost of capital), revenue
growth rates, contributory asset charges, customer attrition, income tax rates and working capital needs, which were based on
current market conditions and were consistent with internal management projections.

Based on the results of the valuation, the carrying amount of certain long-lived assets for the Fyfe North America asset

group exceeded the fair value. Accordingly, we recorded impairment charges of $3.4 million to trademarks, $20.8 million to
customer relationships and $16.8 million to patents and acquired technology in the third quarter of 2017. The impairment
charges were recorded to “Definite-lived intangible asset impairment” in the Consolidated Statement of Operations. Property,
plant and equipment was determined to have a carrying value that exceeded fair value; thus, no impairment was recorded.

The fair value estimates described above were determined using observable inputs and significant unobservable inputs,

which are based on level 3 inputs as defined in Note 13.

Goodwill

Under FASB ASC 350, we assess recoverability of goodwill on an annual basis or when events or changes in

circumstances indicate that the carrying amount of goodwill may not be recoverable. An impairment charge will be recognized
to the extent that the fair value of a reporting unit is less than its carrying value. Factors that could potentially trigger an
impairment review include (but are not limited to):

•

significant underperformance of a segment relative to expected, historical or forecasted operating results;

significant negative industry or economic trends;

significant changes in the strategy for a segment including extended slowdowns in the segment’s market;

a decrease in market capitalization below our book value; and

a significant change in regulations.

Whether during the annual impairment assessment or during a trigger-based impairment review, we determine the fair
value of our reporting units and compare such fair value to the carrying value of those reporting units to determine if there are
any indications of goodwill impairment.

Fair value of reporting units is determined using a combination of two valuation methods: a market approach and an
income approach with each method given equal weight in determining the fair value assigned to each reporting unit. Absent an
indication of fair value from a potential buyer or similar specific transaction, we believe the use of these two methods provides
a reasonable estimate of a reporting unit’s fair value. Assumptions common to both methods are operating plans and economic
outlooks, which are used to forecast future revenues, earnings and after-tax cash flows for each reporting unit. These
assumptions are applied consistently for both methods.

The market approach estimates fair value by first determining earnings before interest, taxes, depreciation and amortization

(“EBITDA”) multiples for comparable publicly-traded companies with similar characteristics of the reporting unit. The
EBITDA multiples for comparable companies are based upon current enterprise value. The enterprise value is based upon
current market capitalization and includes a control premium. We believe this approach is appropriate because it provides a fair
value estimate using multiples from entities with operations and economic characteristics comparable to its reporting units.

The income approach is based on forecasted future (debt-free) cash flows that are discounted to present value using factors

that consider timing and risk of future cash flows. We believe this approach is appropriate because it provides a fair value
estimate based upon the reporting unit’s expected long-term operating cash flow performance. Discounted cash flow
projections are based on financial forecasts developed from operating plans and economic outlooks, growth rates, estimates of
future expected changes in operating margins, terminal value growth rates, future capital expenditures and changes in working
capital requirements. Estimates of discounted cash flows may differ from actual cash flows due to, among other things,
changes in economic conditions, changes to business models, changes in our weighted average cost of capital, or changes in
operating performance.

The discount rate applied to the estimated future cash flows is one of the most significant assumptions utilized under the
income approach. We determine the appropriate discount rate for each of its reporting units based on the weighted average cost
of capital (“WACC”) for each individual reporting unit. The WACC takes into account both the pre-tax cost of debt and cost of
equity (including the risk-free rate on twenty year U.S. Treasury bonds), and certain other company-specific and market-based
factors. As each reporting unit has a different risk profile based on the nature of its operations, the WACC for each reporting
unit is adjusted, as appropriate, to account for company-specific risks. Accordingly, the WACC for each reporting unit may
differ.

Annual Impairment Assessment – October 1, 2018

We had six reporting units for purposes of assessing goodwill at October 1, 2018 as follows: Municipal Pipe

Rehabilitation, Fyfe, Corrpro, United Pipeline Systems, Coating Services and Energy Services. During 2018, we acquired
Hebna and P2S (see Note 1) and integrated them into the United Pipeline Systems and Energy Services reporting units,
respectively.

Significant assumptions used in our October 2018 goodwill review included: (i) discount rates ranging from 13.0% to
16.0%; (ii) compound annual growth rates for revenues generally ranging from -3.2% to 4.8%; (iii) gross margin stability in the
short term related to certain reporting units affected by the 2017 Restructuring, but slightly increased gross margins long term;
(iv) peer group EBITDA multiples; and (v) terminal values for each reporting unit using a long-term growth rate of 1.0% to
3.0%.

Our assessment of each reporting unit’s fair value in relation to its respective carrying value yielded one reporting unit with

a fair value within 15 percent of its carrying value and no reporting units with a fair value below carrying value or within 10
percent of its carrying value. The reporting unit with a fair value within 15 percent of its carrying value was the Energy
Services reporting unit, which had $48.0 million of goodwill recorded at the impairment testing date. The Energy Services
reporting unit has several large customers and primarily operates in the California downstream oil and gas market, which has
experienced significant market changes in recent years Projected cash flows were based on continued strength in the Central
California downstream energy market and a continued, growing relationship with our primary customer base. If these
assumptions do not materialize in a manner consistent with our expectations, there is risk of impairment to recorded goodwill.

Impairment Review – 2017

As part of the 2017 Restructuring, which was approved by our board of directors on July 28, 2017, we exited all non-pipe
related contract applications for the Tyfo® system in North America. As a result of this action, we evaluated the goodwill of our
Fyfe reporting unit and determined that a triggering event occurred. As such, we engaged a third-party valuation firm to assist
management in performing a goodwill impairment review for our Fyfe reporting unit during the third quarter of 2017. In
accordance with the provisions of FASB ASC 350, we determined the fair value of the reporting unit and compared such fair
value to the carrying value of the reporting unit. For the Fyfe reporting unit, carrying value, as adjusted for the long-lived asset
impairments discussed previously, exceeded fair value by approximately 45%.

Despite our recent investments in sales resources to drive growth in North America, FRP technology has become more

widely accepted and more contractors have become proficient with installation, which has begun to commoditize the
application of the Tyfo® system during construction in the North American civil structure market. As a result of this and other
factors, we decided to exit all non-pipe related contract applications for the Tyfo® system in North America. We are now
focused on using our expertise in FRP technologies to promote third-party product sales, continuing pipe-related FRP
installations and providing technical engineering support in the civil structural market in North America. The FRP operation in
Asia remains largely unchanged as market conditions remain favorable.

Our decision, as noted above, lowered the expected future cash flows of the reporting unit. As a result, the values derived

from both the income approach and the market approach decreased from the October 1, 2016 annual goodwill impairment
analysis. The fair value for the Fyfe reporting unit decreased $105.2 million, or 65.3%, from the previous analysis. The
impairment analysis assumed a weighted average cost of capital of 17.0%, which is higher than the 16.0% utilized in the
October 1, 2016 review, primarily due to rising risk-free rates on twenty-year U.S. Treasury bonds. The company-specific
factors influencing discount rates remained consistent in both analyses. The impairment analysis also assumed a long-term
growth rate of 2.5%, which was reduced from 3.5% used in the October 1, 2016 review. This change reflects our expectations
for future annual revenue growth, which were lowered from 10.8% in the previous analysis to 4.0%, primarily due to the
downsizing of the North American operations. Expected gross margins were consistent between both analyses.

As of January 1, 2017, we adopted FASB Accounting Standards Update No. 2017-04, Simplifying the Test for Goodwill

Impairment, which states that an impairment charge should be recognized for the amount by which the carrying amount
exceeds the reporting unit’s fair value. Based on the impairment analysis, we determined that recorded goodwill at the Fyfe
reporting unit was impaired by $45.4 million, which was recorded to “Goodwill impairment” in the Consolidated Statement of
Operations during the third quarter of 2017. As of December 31, 2017, we had remaining Fyfe goodwill of $9.6 million.

Projected cash flows were based, in part, on the ability to grow third-party product sales and pressure pipe contracting in North
America, and maintaining a presence in other international markets. If these assumptions do not materialize in a manner
consistent with our expectations, there is risk of additional impairment to recorded goodwill.

See Note 7 to the consolidated financial statements contained in this Report for a reconciliation of the beginning and

ending balances of goodwill.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

Market Risk

We are exposed to the effect of interest rate changes and of foreign currency and commodity price fluctuations. We
currently do not use derivative contracts to manage commodity risks. From time to time, we may enter into foreign currency
forward contracts to fix exchange rates for net investments in foreign operations to hedge our foreign exchange risk.

Interest Rate Risk

The fair value of our cash and short-term investment portfolio at December 31, 2018 approximated carrying value. Given

the short-term nature of these instruments, market risk, as measured by the change in fair value resulting from a hypothetical
100 basis point change in interest rates, would not be material.

Our objectives in managing exposure to interest rate changes are to limit the impact of interest rate changes on earnings

and cash flows and to lower overall borrowing costs. To achieve these objectives, we maintain fixed rate debt whenever
favorable; however, the majority of our debt at December 31, 2018 was variable rate debt. We substantially mitigate our
interest rate risk through interest rate swap agreements, which are used to hedge the volatility of monthly LIBOR rate
movement of our debt. We currently utilize interest rate swap agreements with a notional amount that mirrors approximately
75% of our outstanding borrowings from the term loan under our amended Credit Facility.

At December 31, 2018, the estimated fair value of our long-term debt was approximately $307.7 million. Fair value was

estimated using market rates for debt of similar risk and maturity and a discounted cash flow model. Market risk related to the
potential increase in fair value resulting from a hypothetical 100 basis point increase in our debt specific borrowing rates at
December 31, 2018 would result in a $0.8 million increase in interest expense.

Foreign Exchange Risk

We operate subsidiaries and are associated with licensees and affiliated companies operating solely outside of the United
States and in foreign currencies. Consequently, we are inherently exposed to risks associated with the fluctuation in the value
of the local currencies compared to the U.S. dollar. At December 31, 2018, a substantial portion of our cash and cash
equivalents was denominated in foreign currencies, and a hypothetical 10.0% change in currency exchange rates could result in
an approximate $5.0 million impact to our equity through accumulated other comprehensive income (loss).

In order to help mitigate this risk, we may enter into foreign exchange forward contracts to minimize the short-term impact

of foreign currency fluctuations. We do not engage in hedging transactions for speculative investment reasons. There can be
no assurance that our hedging operations will eliminate or substantially reduce risks associated with fluctuating currencies. At
December 31, 2018, there were no material foreign currency hedge instruments outstanding. See Note 13 to the consolidated
financial statements contained in this Report for additional information and disclosures regarding our derivative financial
instruments.

Commodity Risk

We have exposure to the effect of limitations on supply and changes in commodity pricing relative to a variety of raw
materials that we purchase and use in our operating activities, most notably resin, iron ore, chemicals, staple fiber, fuel, metals
and pipe. We manage this risk by entering into agreements with certain suppliers utilizing a request for proposal, or RFP,
format and purchasing in bulk, and advantageous buying on the spot market for certain metals, when possible. We also manage
this risk by continuously updating our estimation systems for bidding contracts so that we are able to price our products and
services appropriately to our customers. However, we face exposure on contracts in process that have already been priced and
are not subject to any cost adjustments in the contract. This exposure is potentially more significant on our longer-term
projects.

We obtain a majority of our global resin requirements, one of our primary raw materials, from multiple suppliers in order

to diversify our supplier base and thus reduce the risks inherent in concentrated supply streams. We have qualified a number of
59

vendors in North America, Europe and Asia that can deliver, and are currently delivering, proprietary resins that meet our
specifications.

The primary products and raw materials used by our infrastructure rehabilitation operations in the manufacture of FRP

composite systems are carbon, glass, resins, fabric and epoxy raw materials. Fabric and epoxies are the largest materials
purchased, which are currently purchased through a select group of suppliers, although we believe these and the other materials
are available from a number of vendors. The price of epoxy historically is affected by the price of oil. In addition, a number of
factors such as worldwide demand, labor costs, energy costs, import duties and other trade restrictions may influence the price
of these raw materials.

We rely on a select group of third-party extruders to manufacture our Fusible PVC® pipe products.

Management’s Report on Internal Control Over Financial Reporting

The Company’s management is responsible for establishing and maintaining adequate internal control over financial reporting,
as such term is defined in Exchange Act Rule 13a-15(f).

Under the supervision and with the participation of Company management, including the Chief Executive Officer (the principal
executive officer) and the Chief Financial Officer (the principal financial officer), an evaluation was performed of the
effectiveness of the Company’s internal control over financial reporting as of December 31, 2018. In performing this
evaluation, management employed the criteria set forth by the Committee of Sponsoring Organizations of the Treadway
Commission in Internal Control – Integrated Framework (2013).

Based on the criteria set forth in Internal Control – Integrated Framework (2013), management, including the Company’s
Chief Executive Officer and its Chief Financial Officer, has concluded that the Company’s internal control over financial
reporting was effective as of December 31, 2018.

Because of inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also,
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate
because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

The effectiveness of the Company’s internal control over financial reporting as of December 31, 2018 has been audited by
PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in its report which appears herein.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of Aegion Corporation:

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Aegion Corporation and its subsidiaries (the “Company”) as of
December 31, 2018 and 2017, and the related consolidated statements of operations, comprehensive income, equity and cash flows
for each of the three years in the period ended December 31, 2018, including the related notes (collectively referred to as the
“consolidated financial statements”). We also have audited the Company’s internal control over financial reporting as of December
31, 2018, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring
Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of
the Company as of December 31, 2018 and 2017, and the results of its operations and its cash flows for each of the three years in the
period ended December 31, 2018 in conformity with accounting principles generally accepted in the United States of America. Also
in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December
31, 2018, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.

Basis for Opinions

The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control
over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the
accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express opinions on the
Company’s consolidated financial statements and on the Company’s internal control over financial reporting based on our audits.
We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are
required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules
and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the
audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether
due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of
the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such
procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial
statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as
well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial
reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material
weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk.
Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our
audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability
of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted
accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain
to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of
the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial
statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being
made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance
regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a
material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also,
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because
of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

AEGION CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. DESCRIPTION OF BUSINESS

Aegion Corporation combines innovative technologies with market leading expertise to maintain, rehabilitate and
strengthen pipelines and other infrastructure around the world. Since 1971, the Company has played a pioneering role in
finding transformational solutions to rehabilitate aging infrastructure, primarily pipelines in the wastewater, water, energy,
mining and refining industries. The Company also maintains the efficient operation of refineries and other industrial facilities
and provide innovative solutions for the strengthening of buildings, bridges and other structures. Aegion is committed to
Stronger. Safer. Infrastructure®. The Company believes that the depth and breadth of its products and services platform make
Aegion a leading “one-stop” provider for the world’s infrastructure rehabilitation and protection needs.

The Company is primarily built on the premise that it is possible to use technology to extend the structural design life and

maintain, if not improve, the performance of infrastructure, mostly pipe. The Company is proving that this expertise can be
applied in a variety of markets to protect pipelines in oil, gas, mining, wastewater and water applications and extending this to
the rehabilitation and maintenance of commercial structures and the provision of professional services in energy-related
industries. Many types of infrastructure must be protected from the corrosive and abrasive materials that pass through or near
them. The Company’s expertise in non-disruptive corrosion engineering and abrasion protection is now wide-ranging, opening
new markets for growth. The Company has a long history of product development and intellectual property management. The
Company manufactures most of the engineered solutions it creates as well as the specialized equipment required to install them.
Finally, decades of experience give the Company an advantage in understanding municipal, energy, mining, industrial and
commercial customers. Strong customer relationships and brand recognition allow the Company to support the expansion of
existing and innovative technologies into new high growth end markets.

The Company’s predecessor was originally incorporated in Delaware in 1980 to act as the exclusive United States licensee
of the Insituform® cured-in-place pipe (“CIPP”) process, which Insituform’s founder invented in 1971. The Insituform® CIPP
process served as the first trenchless technology for rehabilitating sewer pipelines and has enabled municipalities and private
industry to avoid the extraordinary expense and extreme disruption that can result from conventional “dig-and-replace”
methods. For more than 45 years, the Company has maintained its leadership position in the CIPP market from manufacturing
to technological innovations and market share.

In order to strengthen the Company’s ability to service the emerging demands of the infrastructure protection market and to

better position the Company for sustainable growth, the Company embarked on a diversification strategy in 2009 to expand its
product and service portfolio and its geographical reach. Through a series of strategic initiatives and key acquisitions, the
Company now possesses a broad portfolio of cost-effective solutions for rehabilitating and maintaining aging or deteriorating
infrastructure, protecting new infrastructure from corrosion worldwide and providing integrated professional services in
engineering, procurement, construction, maintenance, and turnaround services for oil and natural gas companies, primarily in
the midstream and downstream markets.

Recognizing that the breadth of offerings expanded beyond the Company’s flagship Insituform® brand, which constituted
less than half of the Company’s revenues in 2011, the Company reorganized Insituform Technologies, Inc. (“Insituform”), the
parent company at the time, into a new holding company structure in October 2011. Aegion became the new parent company
and Insituform became a wholly-owned subsidiary of Aegion. Aegion reflects the Company’s mission of extending its
leadership capabilities to furnish products and services to provide: (i) long-term protection for water and wastewater pipes, oil
and gas pipelines and infrastructure as well as commercial and governmental structures and transportation infrastructure; and
(ii) integrated professional services to energy companies.

Revision

The Company identified errors related to intercompany accounts, stock compensation and accrued contract costs prior to
December 31, 2015 of approximately $8.9 million and corrected these errors as a cumulative decrease to beginning retained
earnings of $8.9 million with a corresponding increase to accrued expenses, additional paid-in capital and accumulated other
comprehensive loss of $0.8 million, $0.3 million and $7.8 million, respectively, as of December 31, 2015. The Company also
revised the results for 2017 and 2016 to reflect the correction of these errors, resulting in: (i) a net increase to operating
expenses of $0.3 million and a corresponding decrease in net income (loss) for 2017; (ii) an increase to currency translation
adjustments, which is a component of accumulated other comprehensive loss, of $1.4 million for 2017; (iii) a decrease of $1.1
million and an increase of $0.8 million related to equity-based compensation expense for 2017 and 2016, respectively; and (iv)
a decrease to cost of revenues of $0.8 million and an increase to operating expenses of $0.8 million for 2016. The Company
also revised net cash provided by operating activities, which resulted in a decrease of $1.4 million for 2017.

The Company evaluated the impact of these errors on the prior period quarterly and annual financial statements, assessing

materiality both quantitatively and qualitatively. The Company determined that these errors were not material to any of the
Company’s prior annual and interim period consolidated financial statements and therefore, amendments of previously filed
reports were not required. As such, the revision for the corrections is reflected in the financial information of the applicable
prior periods in this Form 10-K filing and disclosure of the revised amount on other prior periods will be reflected in future
filings containing the applicable period.

Acquisitions/Strategic Initiatives/Divestitures

2017 Restructuring

On July 28, 2017, the Company’s board of directors approved a realignment and restructuring plan (the “2017

Restructuring”). As part of the 2017 Restructuring, the Company announced plans to: (i) divest the Company’s pipe coating
and insulation businesses in Louisiana, The Bayou Companies, LLC and Bayou Wasco Insulation, LLC (collectively “Bayou”;
(ii) exit all non-pipe related contract applications for the Tyfo® system in North America; (iii) right-size the cathodic protection
services operation in Canada and the CIPP businesses in Australia and Denmark; and (iv) reduce corporate and other operating
costs.

2016 Restructuring

On January 4, 2016, the Company’s board of directors approved a restructuring plan (the “2016 Restructuring”) to reduce

the Company’s exposure to the upstream oil markets and to reduce consolidated expenses. The 2016 Restructuring
repositioned Energy Services’ upstream operations in California, reduced Corrosion Protection’s upstream exposure by
divesting its interest in a Canadian pipe coating joint venture, right-sized Corrosion Protection to compete more effectively and
reduced corporate and other operating costs. The Company completed all of the aforementioned objectives related to the 2016
Restructuring. See Note 4.

Infrastructure Solutions Segment (“Infrastructure Solutions”)

On November 1, 2018, the Company sold substantially all of the fixed assets and inventory from its CIPP operations in
Denmark for a sale price of DKK 10.5 million (approximately $1.6 million). In connection with the sale, the Company entered
into a five-year exclusive tube-supply agreement whereby the buyers will purchase Insituform® CIPP liners from the Company.
The buyers are also entitled to use the Insituform® trade name based on a trademark license granted for the same five-year time
period.

On May 14, 2018, the Company’s board of directors approved a plan to divest the Company’s CIPP business in Australia.
While restructuring actions in Australia led to year-over-year improvements in operating results in 2018, an assessment of the
long-term fit within the Company’s portfolio led to the decision to divest the business. Accordingly, the Company has
classified Australia’s assets and liabilities as held for sale on the Consolidated Balance Sheet at December 31, 2018. See Note
6.

On March 1, 2017, the Company acquired Environmental Techniques Limited and its parent holding company, Killeen
Trading Limited (collectively “Environmental Techniques”), for a purchase price of £6.5 million, approximately $8.0 million,
which was funded from the Company’s international cash balances. Environmental Techniques provides trenchless drainage
inspection, cleaning and rehabilitation services throughout the United Kingdom and the Republic of Ireland.

On July 1, 2016, the Company acquired Concrete Solutions Limited (“CSL”) and Building Chemical Supplies Limited
(“BCS”), two New Zealand companies (collectively, “Concrete Solutions”), for a purchase price paid at closing of NZD 7.5
million, approximately $5.5 million, which was funded from the Company’s cash balances. The sellers have the ability to earn
up to an additional NZD 2.0 million, approximately $1.4 million, of proceeds based on reaching certain future performance
targets. CSL provides structural strengthening, concrete repair and bridge jointing solutions primarily through application of
FRP and injection resins and had served as a Tyfo® system certified applicator in New Zealand since the late 1990’s. BCS
imports and distributes materials, including fiber reinforced polymer, injection resins, repair mortars and protective coatings.

On June 2, 2016, the Company acquired the CIPP contracting operations of Leif M. Jensen A/S (“LMJ”), a Danish
company and the Insituform licensee in Denmark since 2011. The purchase price was €2.9 million , approximately $3.2
million, and was funded from the Company’s cash balances.

On May 13, 2016, the Company acquired the operations and territories of Fyfe Europe S.A. and related companies (“Fyfe

Europe”) for a purchase price of $3.0 million. The transaction was funded from the Company’s cash balances. Fyfe Europe

held rights to provide Fyfe® product engineering and support to installers and applicators of FRP systems in 72 countries
throughout Europe, the Middle East and North Africa. The acquisition of these territories provides the Company with
worldwide rights to market, manufacture and install the patented Tyfo® technology.

On February 18, 2016, the Company acquired Underground Solutions, Inc. and its subsidiary, Underground Solutions

Technologies Group, Inc. (collectively, “Underground Solutions”), for an initial purchase price of $85.0 million plus an
additional $5.0 million for the value of the estimated tax benefits associated with Underground Solutions’ net operating loss
carry forwards. The purchase price included $6.3 million held in escrow as security for the post-closing purchase price
adjustments and post-closing indemnification obligations of Underground Solutions’ previous owners. The transaction was
funded partially from the Company’s cash balances and partially from borrowings under the Company’s revolving credit
facility. To supplement the domestic cash balances, the Company repatriated approximately $29.7 million from foreign
subsidiaries to assist in funding the transaction, incurring approximately $3.2 million in additional taxes, an accrual for which
was included in the Company’s tax provision amounts for 2015. Underground Solutions provides infrastructure technologies
for water, sewer and conduit applications.

Corrosion Protection Segment (“Corrosion Protection”)

On August 31, 2018, the Company sold substantially all of the assets of its wholly-owned subsidiary, The Bayou
Companies, LLC and its fifty-one percent (51%) interest in Bayou Wasco Insulation, LLC. The sale price was $46 million,
consisting of $38 million paid in cash at closing and $8 million in a fully secured, two-year loan payable to Aegion. Aegion is
also eligible to receive an additional $4 million in total earn-out payments based on performance of the divested businesses in
2019 and 2020. Cash proceeds, net of customary closing costs, were used to repay outstanding borrowings on the Company’s
line of credit. The sale resulted in a pre-tax loss of $7.0 million during 2018, which was corrected from the $8.7 million
previously reported in the third quarter of 2018. The loss is included in “Other expense” in the Consolidated Statements of
Operations.

On May 4, 2018, the Company acquired the operations of Hebna Inc., Hebna Canada Inc. and Hebna Corporation

(collectively “Hebna”), for a total purchase price of $6.0 million ($3.0 million was paid during the second quarter of 2018 and
$3.0 million was paid during the third quarter of 2018). The transaction was funded from a combination of domestic and
international cash balances, with fifty percent (50%) of the purchase price being paid by the Company’s joint venture in Oman,
in which the Company is a fifty-one percent (51%) partner. Hebna provides pipeline lining services, including compressed-fit
lining, slip-lining, liner and free-standing pipe fusing, pipeline assessment and integrity management, pipeline pigging and
calibration, and roto-lining services primarily in the United States, Canada and Middle East.

In September 2017, the Company organized Aegion South Africa Proprietary Limited, a joint venture in South Africa
between Aegion International Holdings Limited, a subsidiary of the Company (“Aegion International”), and Robor Proprietary
Limited (“Robor”), for the purpose of providing Aegion’s Corrosion Protection and Infrastructure Solutions products and
services to Eastern and Southern Africa. Aegion International owns sixty percent (60%) of the joint venture and Robor owns
the remaining forty percent (40%).

On February 1, 2016, the Company sold its fifty-one percent (51%) interest in its Canadian pipe-coating joint venture,
Bayou Perma-Pipe Canada, Ltd. (“BPPC”), to its joint venture partner, Perma-Pipe, Inc. The sale price was $9.6 million, which
consisted of a $7.6 million payment at closing and a $2.0 million promissory note, which was paid in full on July 28, 2016.
BPPC served as the Company’s pipe coating and insulation operation in Canada.

Energy Services Segment (“Energy Services”)

On July 20, 2018, the Company acquired the operations of Plant Performance Services LLC and P2S LLC (collectively
“P2S”), for a total purchase price of $3.0 million. The transaction was funded from domestic cash balances. P2S specializes in

The transaction purchase price to acquire Environmental Techniques was £6.5 million, approximately $8.0 million, which

represented cash consideration paid at closing.

The transaction purchase price to acquire Underground Solutions was $88.4 million, which included: (i) a payment at
closing of $85.0 million; (ii) a payment of $5.0 million for the value of the estimated tax benefits associated with Underground
Solutions’ net operating loss carry forwards; and (iii) working capital adjustments of $1.6 million payable to the Company.

The transaction purchase price to acquire Fyfe Europe was $3.0 million, which represented cash consideration paid at

closing of $2.8 million plus $0.2 million of deferred contingent consideration, which was paid during 2017.

The transaction purchase price to acquire LMJ was €2.9 million , approximately $3.2 million, which was paid at closing.

The transaction purchase price to acquire Concrete Solutions was NZD 8.9 million, approximately $6.4 million, which

included: (i) a payment at closing of NZD 7.5 million, approximately $5.5 million; (ii) a preliminary working capital
adjustment payable to the sellers of NZD 0.2 million, approximately $0.1 million; and (iii) the estimated fair value of earnout
consideration of NZD 1.2 million, approximately $0.9 million. During 2018 and 2017, the Company reversed $0.3 million and
$0.1 million, respectively, of the earnout consideration as operating results for the twelve-month periods ended June 30, 2018
and 2017 were below the target amounts in the purchase agreement. The accrual adjustments resulted in an offset to
“Operating expenses” in the Consolidated Statement of Operations for each respective year. After the accrual adjustments, the
estimated fair value of the contingent consideration was NZD 0.6 million, approximately $0.4 million. The fair value estimate
was determined using observable inputs and significant unobservable inputs, which are based on level 3 inputs as defined in
Note 13.

2. ACCOUNTING POLICIES

Principles of Consolidation

The consolidated financial statements include the accounts of the Company, its wholly-owned subsidiaries and majority-
owned subsidiaries in which the Company is deemed to be the primary beneficiary. All significant intercompany transactions
and balances have been eliminated.

Accounting Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States
requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure
of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.

Foreign Currency

For the Company’s international subsidiaries, the local currency is generally the functional currency. Assets and liabilities
of these subsidiaries are translated into U.S. dollars using rates in effect at the balance sheet date while revenues and expenses
are translated into U.S. dollars using average exchange rates. The cumulative translation adjustment resulting from changes in
exchange rates are included in the Consolidated Balance Sheets as a component of “Accumulated other comprehensive loss” in
total stockholders’ equity.

The Company’s accumulated other comprehensive loss is comprised of three main components: (i) currency translation;

(ii) derivatives; and (iii) gains and losses associated with the Company’s defined benefit plan in the United Kingdom (in
thousands):

Net foreign exchange transaction losses of $0.6 million, $2.2 million and $0.9 million for 2018, 2017 and 2016,

respectively, are included in “Other expense” in the Consolidated Statements of Operations.

Research and Development

The Company expenses research and development costs as incurred. Research and development costs of $5.6 million, $4.2

million and $4.7 million for the years ended December 31, 2018, 2017 and 2016, respectively, are included in “Operating
expenses” in the consolidated statements of operations.

Taxation

The Company provides for estimated income taxes payable or refundable on current year income tax returns as well as the
estimated future tax effects attributable to temporary differences and carryforwards, based upon enacted tax laws and tax rates,
and in accordance with FASB ASC 740, Income Taxes (“FASB ASC 740”). FASB ASC 740 also requires that a valuation
allowance be recorded against any deferred tax assets that are not likely to be realized in the future. The determination is based
on the Company’s ability to generate future taxable income and, at times, is dependent on its ability to implement strategic tax
initiatives to ensure full utilization of recorded deferred tax assets. Should the Company not be able to implement the necessary
tax strategies, it may need to record valuation allowances for certain deferred tax assets, including those related to foreign
income tax benefits. Significant management judgment is required in determining the provision for income taxes, deferred tax
assets and liabilities and any valuation allowances recorded against net deferred tax assets.

As a result of the reduction in the U.S. corporate income tax rate from 35% to 21% under the Tax Cuts and Jobs Act
(“TCJA”), FASB ASC 740 required the Company to remeasure its deferred tax assets and liabilities based on tax rates at which
the balances are expected to reverse in the future. The amount recorded for the remeasurement of the Company’s deferred tax
balances resulted in no adjustment to income tax expense. The remeasurement of the deferred tax assets gave rise to an
additional income tax expense of $5.1 million in 2017, which was offset by an equal reduction in the valuation allowance of
$5.1 million.

In accordance with FASB ASC 740, tax benefits from an uncertain tax position may be recognized when it is more likely

than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation
processes, based on the technical merits. In addition, this recognition model includes a measurement attribute that measures the
position as the largest amount of tax that is greater than 50% likely of being realized upon ultimate settlement in accordance
with FASB ASC 740. This interpretation also provides guidance on derecognition, classification, interest and penalties,
accounting in interim periods, disclosure and transition.

The Company recognizes tax liabilities in accordance with FASB ASC 740 and adjusts these liabilities when judgment

changes as a result of the evaluation of new information not previously available. Due to the complexity of some of these
uncertainties, the ultimate resolution may result in a payment that is materially different from the current estimate of the tax
liabilities. These differences will be reflected as increases or decreases to income tax expense in the period in which they are
determined. While the Company believes the resulting tax balances as of December 31, 2018 and 2017 were appropriately
accounted for in accordance with FASB ASC 740, the ultimate outcome of such matters could result in favorable or unfavorable
adjustments to the consolidated financial statements and such adjustments could be material.

In 2017, in connection with its initial analysis of the TCJA, the Company recorded a provisional estimated net income tax

expense of $2.4 million by applying the guidance under Staff Accounting Bulletin No. 118, Income Tax Accounting
Implications of the Tax Cuts and Jobs Act (“SAB 118”). In accordance with SAB 118, the estimated income tax represented the
Company’s best estimate at the time it was made, but also understanding that the provisional amount was subject to further
adjustments under SAB 118. During 2018, the Company finalized its calculations of the transition tax liability under the TCJA
and adjusted the liability downward by $1.9 million primarily due to further refinement of computations related to earnings and

profits, cash and cash equivalents, state income tax and foreign withholding taxes pursuant to guidance issued during the year.
This adjustment was recorded as a reduction to income tax expense in 2018.

Refer to Note 11 for additional information regarding taxes on income and the impact of the TCJA.

The Company excluded 735,577 stock options and restricted and deferred stock units in 2017 from the diluted earnings per

share calculation for the Company’s common stock because of the reported net loss for the period. The Company excluded
4,049, 73,897 and 77,807 stock options in 2018, 2017 and 2016, respectively, from the diluted earnings per share calculations
for the Company’s common stock because they were anti-dilutive as their exercise prices were greater than the average market
price of common shares for each period.

Purchase Price Accounting

The Company accounts for its acquisitions in accordance with FASB ASC 805, Business Combinations. The base cash

purchase price plus the estimated fair value of any non-cash or contingent consideration given for an acquired business is
allocated to the assets acquired (including identified intangible assets) and liabilities assumed based on the estimated fair values
of such assets and liabilities. The excess of the total consideration over the aggregate net fair values assigned is recorded as
goodwill. Contingent consideration, if any, is recognized as a liability as of the acquisition date with subsequent adjustments
recorded in the consolidated statements of operations. Indirect and general expenses related to business combinations are
expensed as incurred.

The Company typically determines the fair value of tangible and intangible assets acquired in a business combination using

Classification of Current Assets and Current Liabilities

The Company includes in current assets and current liabilities certain amounts realizable and payable under construction
contracts that may extend beyond one year. The construction periods on projects undertaken by the Company generally range
from less than one month to 24 months.

At December 31, 2018, the Company’s balance in contract liabilities was $32.3 million, which decreased $19.3 million

from $51.6 million at December 31, 2017 primarily due to the timing of billing and advance deposits received on certain
projects in the Company’s coating services operation in the Middle East.

Cash, Cash Equivalents and Restricted Cash

The Company classifies highly liquid investments with original maturities of 90 days or less as cash equivalents. Recorded

book values are reasonable estimates of fair value for cash and cash equivalents.

Cash, cash equivalents and restricted cash reported within the Consolidated Balance Sheets and Consolidated Statements of

Cash Flows are as follows (in thousands):

(1) Amounts exclude $1.0 million of cash and cash equivalents classified as held for sale at December 31, 2017 (see Note 6).

Restricted cash held in escrow primarily relates to funds reserved for legal requirements, deposits made in lieu of retention
on specific projects performed for municipalities and state agencies, or advance customer payments and compensating balances
for bank undertakings in Europe. Restricted cash related to operations is similar to retainage, and is, therefore, classified as a
current asset, consistent with the Company’s policy on retainage.

Inventories

Inventories are stated at the lower of cost (first-in, first-out) or market. Actual cost is used to value raw materials and
supplies. Standard cost, which approximates actual cost, is used to value work-in-process, finished goods and construction
materials. Standard cost includes direct labor, raw materials and manufacturing overhead based on normal capacity. For
certain businesses within our Corrosion Protection segment, the Company uses actual costs or average costs for all classes of
inventory.

Retainage

Many of the contracts under which the Company performs work contain retainage provisions. Retainage refers to that

portion of revenue earned by the Company but held for payment by the customer pending satisfactory completion of the
project. The Company generally invoices its customers periodically as work is completed. Under ordinary circumstances,
collection from municipalities is made within 60 to 90 days of billing. In most cases, 5% to 15% of the contract value is
withheld by the municipal owner pending satisfactory completion of the project. Collections from other customers are
generally made within 30 to 45 days of billing. Unless reserved, the Company believes that all amounts retained by customers
under such provisions are fully collectible. Retainage on active contracts is classified as a current asset regardless of the term
of the contract. Retainage is generally collected within one year of the completion of a contract, although collection can extend
beyond one year from time to time. As of December 31, 2018, retainage receivables aged greater than 365 days approximated
10% of the total retainage balance and collectibility was assessed as described in the allowance for doubtful accounts section
below.

Allowance for Doubtful Accounts

Management makes estimates of the uncollectibility of accounts receivable and retainage. The Company records an
allowance based on specific accounts to reduce receivables, including retainage, to the amount that is expected to be collected.
The specific allowances are reevaluated and adjusted as additional information is received. After all reasonable attempts to
collect the receivable or retainage have been explored, the account is written off against the allowance. The Company also
includes reserves related to certain accounts receivable that may be in litigation or dispute.

Long-Lived Assets

Property, plant and equipment and other identified intangibles (primarily customer relationships, patents and acquired

technologies, trademarks, licenses and non-compete agreements) are recorded at cost, net of accumulated depreciation,
amortization and impairment, and, except for goodwill, are depreciated or amortized on a straight-line basis over their
estimated useful lives. Changes in circumstances such as technological advances, changes to the Company’s business model or
changes in the Company’s capital strategy can result in the actual useful lives differing from the Company’s estimates. If the
Company determines that the useful life of its property, plant and equipment or its identified intangible assets should be
shortened, the Company would depreciate or amortize the net book value in excess of the salvage value over its revised
remaining useful life, thereby increasing depreciation or amortization expense.

Long-lived assets, including property, plant and equipment and other intangibles, are reviewed for impairment whenever
events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Such impairment tests
are based on a comparison of undiscounted cash flows to the recorded value of the asset. The estimate of cash flow is based
upon, among other things, assumptions about expected future operating performance. The Company’s estimates of
undiscounted cash flow may differ from actual cash flow due to, among other things, technological changes, economic
conditions, changes to its business model or changes in its operating performance. If the sum of the undiscounted cash flows is
less than the carrying value, the Company recognizes an impairment loss, measured as the amount by which the carrying value
exceeds the fair value of the asset.

Impairment Review – 2017

As part of the 2017 Restructuring, which was approved by the Company’s board of directors on July 28, 2017, the

Company exited all non-pipe related contract applications for the Tyfo® system in North America. As a result of this action, the
Company evaluated the long-lived assets of its Fyfe reporting unit, which caused the Company to review the financial
performance of at-risk asset groups within the Fyfe reporting unit in accordance with FASB ASC 360, Property, Plant and
Equipment (“FASB ASC 360”). The results of the Fyfe reporting unit and its related asset groups are reported within the
Infrastructure Solutions reportable segment.

The assets of an asset group represent the lowest level for which identifiable cash flows can be determined independent of

other groups of assets and liabilities. The Fyfe North America asset group was the only at-risk asset group reviewed for
impairment. The Company developed internal forward business plans under the guidance of local and regional leadership to
determine the undiscounted expected future cash flows derived from Fyfe North America’s long-lived assets. Such were based
on management’s best estimates considering the likelihood of various outcomes. Based on the internal projections, the
Company determined that the sum of the undiscounted expected future cash flows for the Fyfe North America asset group was
less than the carrying value of the assets, and as a result, engaged a third-party valuation firm to assist management in
determining the fair value of long-lived assets for the Fyfe North America asset group.

In order to determine the impairment amount of long-lived assets, the Company first determined the fair value of each key
component of its long-lived assets for the Fyfe North America asset group. The fair values were derived using various income-
based approaches, which utilize discounted cash flows to evaluate the net earnings attributable to the asset being measured.
Key assumptions used in assessment include the discount rate (based on weighted-average cost of capital), revenue growth
rates, contributory asset charges, customer attrition, income tax rates and working capital needs, which were based on current
market conditions and were consistent with internal management projections.

Based on the results of the valuation, the carrying amount of certain long-lived assets for the Fyfe North America asset

group exceeded the fair value. Accordingly, the Company recorded impairment charges of $3.4 million to trademarks, $20.8
million to customer relationships and $16.8 million to patents and acquired technology in 2017. The impairment charges were
recorded to “Definite-lived intangible asset impairment” in the Consolidated Statement of Operations. Property, plant and
equipment were determined to have a carrying value that exceeded fair value; thus, no impairment was recorded.

The fair value estimates described above were determined using observable inputs and significant unobservable inputs,

which are based on level 3 inputs as defined in Note 13.

Goodwill

Under FASB ASC 350, the Company assesses recoverability of goodwill on an annual basis or when events or changes in
circumstances indicate that the carrying amount of goodwill may not be recoverable. An impairment charge will be recognized
to the extent that the fair value of a reporting unit is less than its carrying value. Factors that could potentially trigger an
impairment review include (but are not limited to):

•

significant underperformance of a segment relative to expected, historical or forecasted operating results;

significant negative industry or economic trends;

significant changes in the strategy for a segment including extended slowdowns in the segment’s market;

a decrease in market capitalization below the Company’s book value; and

a significant change in regulations.

Whether during the annual impairment assessment or during a trigger-based impairment review, the Company determines

the fair value of its reporting units and compares such fair value to the carrying value of those reporting units to determine if
there are any indications of goodwill impairment.

Fair value of reporting units is determined using a combination of two valuation methods: a market approach and an
income approach with each method given equal weight in determining the fair value assigned to each reporting unit. Absent an
indication of fair value from a potential buyer or similar specific transaction, the Company believes the use of these two
methods provides a reasonable estimate of a reporting unit’s fair value. Assumptions common to both methods are operating
plans and economic outlooks, which are used to forecast future revenues, earnings and after-tax cash flows for each reporting
unit. These assumptions are applied consistently for both methods.

The market approach estimates fair value by first determining earnings before interest, taxes, depreciation and amortization

(“EBITDA”) multiples for comparable publicly-traded companies with similar characteristics of the reporting unit. The
EBITDA multiples for comparable companies are based upon current enterprise value. The enterprise value is based upon
current market capitalization and includes a control premium. The Company believes this approach is appropriate because it
provides a fair value estimate using multiples from entities with operations and economic characteristics comparable to its
reporting units.

The income approach is based on forecasted future (debt-free) cash flows that are discounted to present value using factors
that consider timing and risk of future cash flows. The Company believes this approach is appropriate because it provides a fair
value estimate based upon the reporting unit’s expected long-term operating cash flow performance. Discounted cash flow
projections are based on financial forecasts developed from operating plans and economic outlooks, growth rates, estimates of
future expected changes in operating margins, terminal value growth rates, future capital expenditures and changes in working
capital requirements. Estimates of discounted cash flows may differ from actual cash flows due to, among other things,

changes in economic conditions, changes to business models, changes in the Company’s weighted average cost of capital, or
changes in operating performance.

The discount rate applied to the estimated future cash flows is one of the most significant assumptions utilized under the

income approach. The Company determines the appropriate discount rate for each of its reporting units based on the weighted
average cost of capital (“WACC”) for each individual reporting unit. The WACC takes into account both the pre-tax cost of
debt and cost of equity (including the risk-free rate on twenty year U.S. Treasury bonds), and certain other company-specific
and market-based factors. As each reporting unit has a different risk profile based on the nature of its operations, the WACC for
each reporting unit is adjusted, as appropriate, to account for company-specific risks. Accordingly, the WACC for each
reporting unit may differ.

Annual Impairment Assessment – October 1, 2018

The Company had six reporting units for purposes of assessing goodwill at October 1, 2018 as follows: Municipal Pipe
Rehabilitation, Fyfe, Corrpro, United Pipeline Systems, Coating Services and Energy Services. During 2018, the Company
acquired Hebna and P2S (see Note 1) and integrated them into the United Pipeline Systems and Energy Services reporting
units, respectively.

Significant assumptions used in the Company’s October 2018 goodwill review included: (i) discount rates ranging from

13.0% to 16.0%; (ii) compound annual growth rates for revenues generally ranging from -3.2% to 4.8%; (iii) gross margin
stability in the short term related to certain reporting units affected by the 2017 Restructuring, but slightly increased gross
margins long term; (iv) peer group EBITDA multiples; and (v) terminal values for each reporting unit using a long-term growth
rate of 1.0% to 3.0%.

The Company’s assessment of each reporting unit’s fair value in relation to its respective carrying value yielded one
reporting unit with a fair value within 15 percent of its carrying value and no reporting units with a fair value below carrying
value or within 10 percent of its carrying value. The reporting unit with a fair value within 15 percent of its carrying value was
the Energy Services reporting unit, which had $48.0 million of goodwill recorded at the impairment testing date. The Energy
Services reporting unit has several large customers and primarily operates in the California downstream oil and gas market,
which has experienced significant market changes in recent years Projected cash flows were based on continued strength in the
Central California downstream energy market and a continued, growing relationship with its primary customer base.

Impairment Review – 2017

As part of the 2017 Restructuring, which was approved by the Company’s board of directors on July 28, 2017, the

Company exited all non-pipe related contract applications for the Tyfo® system in North America. As a result of this action, the
Company evaluated the goodwill of its Fyfe reporting unit and determined that a triggering event occurred. As such, the
Company engaged a third-party valuation to assist management in performing a goodwill impairment review for its Fyfe
reporting unit during the third quarter of 2017. In accordance with the provisions of FASB ASC 350, the Company determined
the fair value of the reporting unit and compared such fair value to the carrying value of the reporting unit. For the Fyfe
reporting unit, carrying value, as adjusted for the long-lived asset impairments discussed previously, exceeded fair value by
approximately 45%.

Despite the Company’s recent investments in sales resources to drive growth in North America, FRP technology has
become more widely accepted and more contractors have become proficient with installation, which has begun to commoditize
the application of the Tyfo® system during construction in the North American civil structure market. As a result of this and
other factors, the Company decided to exit all non-pipe related contract applications for the Tyfo® system in North America.
The Company is now focused on using its expertise in FRP technologies to promote third-party product sales, continuing pipe-
related FRP installations and providing technical engineering support in the civil structural market in North America. The FRP
operation in Asia remains largely unchanged as market conditions remain favorable.

The Company’s decision, as noted above, lowered the expected future cash flows of the reporting unit. As a result, the

values derived from both the income approach and the market approach decreased from the October 1, 2016 annual goodwill
impairment analysis. The fair value for the Fyfe reporting unit decreased $105.2 million, or 65.3%, from the previous analysis.
The impairment analysis assumed a weighted average cost of capital of 17.0%, which is higher than the 16.0% utilized in the
October 1, 2016 review, primarily due to rising risk-free rates on twenty-year U.S. Treasury bonds. The company-specific
factors influencing discount rates remained consistent in both analyses. The impairment analysis also assumed a long-term
growth rate of 2.5%, which was reduced from 3.5% used in the October 1, 2016 review. This change reflects the Company’s
expectations for future annual revenue growth, which were lowered from 10.8% in the previous analysis to 4.0%, primarily due
to the downsizing of the North American operations. Expected gross margins were consistent between both analyses.

As of January 1, 2017, the Company adopted FASB Accounting Standards Update No. 2017-04, Simplifying the Test for

Goodwill Impairment, which states that an impairment charge should be recognized for the amount by which the carrying
amount exceeds the reporting unit’s fair value. Based on the impairment analysis, the Company determined that recorded

goodwill at the Fyfe reporting unit was impaired by $45.4 million, which was recorded to “Goodwill impairment” in the
Consolidated Statement of Operations during the third quarter of 2017. As of December 31, 2017, the Company had remaining
Fyfe goodwill of $9.6 million. Projected cash flows were based, in part, on the ability to grow third-party product sales and
pressure pipe contracting in North America, and maintaining a presence in other international markets. If these assumptions do
not materialize in a manner consistent with Company’s expectations, there is risk of additional impairment to recorded
goodwill.

Investments in Variable Interest Entities

The Company evaluates all transactions and relationships with variable interest entities (“VIE”) to determine whether the

Company is the primary beneficiary of the entities in accordance with FASB ASC 810, Consolidation.

The Company’s overall methodology for evaluating transactions and relationships under the VIE requirements includes the

following two steps:

•

determine whether the entity meets the criteria to qualify as a VIE; and

determine whether the Company is the primary beneficiary of the VIE.

In performing the first step, the significant factors and judgments that the Company considers in making the determination

as to whether an entity is a VIE include:

•

the design of the entity, including the nature of its risks and the purpose for which the entity was created, to determine
the variability that the entity was designed to create and distribute to its interest holders;

•

the nature of the Company’s involvement with the entity;

• whether control of the entity may be achieved through arrangements that do not involve voting equity;

• whether there is sufficient equity investment at risk to finance the activities of the entity; and

• whether parties other than the equity holders have the obligation to absorb expected losses or the right to receive

residual returns.

If the Company identifies a VIE based on the above considerations, it then performs the second step and evaluates whether

it is the primary beneficiary of the VIE by considering the following significant factors and judgments:

• whether the entity has the power to direct the activities of a variable interest entity that most significantly impact the

entity’s economic performance; and

• whether the entity has the obligation to absorb losses of the entity that could potentially be significant to the variable

interest entity or the right to receive benefits from the entity that could potentially be significant to the variable interest
entity.

Based on its evaluation of the above factors and judgments, as of December 31, 2018, the Company consolidated any VIEs

in which it was the primary beneficiary.

Financial data for consolidated variable interest entities are summarized in the following tables (in thousands):

Accounting Standards Updates

In August 2018, the FASB issued Accounting Standards Update No. 2018-13, Fair Value Measurement: Disclosure

Framework—Changes to the Disclosure Requirements for Fair Value Measurement, which modifies the disclosure
requirements for Level 1, Level 2 and Level 3 instruments in the fair value hierarchy. The guidance is effective for the
Company’s fiscal year beginning January 1, 2020, including interim periods within that fiscal year. The adoption of this
standard is not expected to have a material impact on its consolidated financial statements.

In February 2018, the FASB issued Accounting Standards Update No. 2018-02, Reclassification of Certain Tax Effects
from Accumulated Other Comprehensive Income, which permits a company to reclassify the income tax effects of the TCJA on
items within accumulated other comprehensive income to retained earnings. The guidance is effective for the Company’s fiscal
year beginning January 1, 2019, including interim periods within that fiscal year. Companies may adopt the new guidance
using one of two transition methods: (i) retrospective to each period (or periods) in which the income tax effects are recognized,
or (ii) at the beginning of the period of adoption. The Company adopted this standard effective January 1, 2019 and elected not
to reclassify the tax effects due to the immaterial impact on the Company’s consolidated financial statements.

In August 2017, the FASB issued Accounting Standards Update No. 2017-12, Derivatives and Hedging (Topic 815):
Targeted Improvements to Accounting for Hedging Activities, which amends the recognition and presentation requirements for
hedge accounting activities. The standard improves the financial reporting of hedging relationships to better portray the
economic results of an entity’s risk management activities in its financial statements and reduces the complexity of applying
hedge accounting. This new guidance is effective for the Company’s fiscal year beginning January 1, 2019, but the Company
early-adopted this standard, effective January 1, 2018. The adoption of this standard did not have a material impact on the
Company’s consolidated financial statements.

In November 2016, the FASB issued Accounting Standards Update No. 2016-18, Statement of Cash Flows (Topic 230):
Restricted Cash, which requires that a statement of cash flows explain the change during the period in the total of cash, cash
equivalents, and restricted cash. As a result, restricted cash is included with cash and cash equivalents when reconciling the
beginning-of-period and end-of-period total amounts shown on the statement of cash flows. This new guidance was effective
for the Company’s fiscal year beginning January 1, 2018 and applied retrospectively. The Company’s adoption of this standard,
effective January 1, 2018, did not have a material impact on its consolidated financial statements, other than the classification
of restricted cash on the Consolidated Statement of Cash Flows.

In August 2016, the FASB issued Accounting Standards Update No. 2016-15, Statement of Cash Flows (Topic 230):
Classification of Certain Cash Receipts and Cash Payments, which addresses diversity in how certain cash receipts and cash
payments are presented and classified in the statement of cash flows. The standard was effective for the Company’s fiscal year
beginning January 1, 2018, the adoption of which did not have a material impact on its consolidated financial statements.

In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (Topic 842), that requires lessees to

present right-of-use assets and lease liabilities on the balance sheet for all leases with lease terms longer than twelve months.
The standard is effective for the Company’s fiscal year beginning January 1, 2019, including interim periods within that fiscal
year. The Company will adopt the new guidance using the cumulative effect method, which would apply to all new lease
contracts initiated on or after January 1, 2019. The Company will also elect the package of practical expedients not to reassess
prior conclusions related to contracts containing leases, lease classification and initial direct costs and the lessee practical
expedient to combine lease and non-lease components. The Company also made a policy election to not recognize right-of-use
assets and lease liabilities for short-term leases for all asset classes.

Based on the Company’s current lease portfolio, adoption of the standard will result in a right-of-use asset and related lease

liability in a range from $60 million to $70 million in the consolidated balance sheets. The impact to the Company’s
consolidated statements of income and consolidated statements of cash flows is not expected to be material. The Company is
also implementing enhanced internal controls and a third-party software solution to support recognition and disclosure under
the new standard.

In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (Topic

606), which replaces revenue recognition requirements regarding contracts with customers to transfer goods or services with a
single revenue recognition model for recognizing revenue. Under the new guidance, entities are required to recognize revenue
to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity
expects to be entitled in exchange for those goods or services. The guidance provides a five-step analysis to be performed on

transactions to determine when and how revenue is recognized. The Company adopted this standard, effective January 1, 2018,
using the modified retrospective transition method. See Note 3.

3. REVENUES

On January 1, 2018, the Company adopted FASB ASC 606, Revenue from Contracts with Customers (“FASB ASC 606”)

for all contracts that were not completed using the modified retrospective transition method. The Company recognized the
cumulative effect of initially applying FASB ASC 606 as an adjustment to the opening balance of retained earnings. Prior
period information has not been restated and continues to be reported under the accounting standards in effect for those periods.

The Company recorded a net reduction to opening retained earnings of $0.3 million as of January 1, 2018 due to the

cumulative impact of adopting FASB ASC 606, with the impact primarily related to royalty license fee revenues. The impact to
revenues for the year ended December 31, 2018 was an increase of $1.8 million as a result of applying FASB ASC 606.

Performance Obligations

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of

account in FASB ASC 606. A contract’s transaction price is allocated to each distinct performance obligation and recognized as
revenue when, or as, the performance obligation is satisfied. For contracts in which construction, engineering and installation
services are provided, there is generally a single performance obligation as the promise to transfer the individual goods or
services is not separately identifiable from other promises in the contracts and, therefore, not distinct. The bundle of goods and
services represents the combined output for which the customer has contracted. For product sales contracts with multiple
performance obligations where each product is distinct, the Company allocates the contract’s transaction price to each
performance obligation using its best estimate of the standalone selling price of each distinct good in the contract. For royalty
license agreements whereby intellectual property is transferred to the customer, there is a single performance obligation as the
license is not separately identifiable from the other goods and services in the contract.

The Company’s performance obligations are satisfied over time as work progresses or at a point in time. Revenues from

products and services transferred to customers over time accounted for 93.5%, 93.5% and 92.2% of revenues for the years
ended December 31, 2018, 2017 and 2016, respectively. Revenues from construction, engineering and installation services are
recognized over time using an input measure (e.g., costs incurred to date relative to total estimated costs at completion) to
measure progress toward satisfying performance obligations. Incurred cost represents work performed, which corresponds
with, and thereby best depicts, the transfer of control to the customer. Contract costs include labor, material, overhead and,
when appropriate, general and administrative expenses. Revenues from maintenance contracts are structured such that the
Company has the right to consideration from a customer in an amount that corresponds directly with the performance
completed to date. Therefore, the Company utilizes the practical expedient in FASB ASC 606-55-255, which allows the
Company to recognize revenue in the amount to which it has the right to invoice. Applying this practical expedient, the
Company is not required to disclose the transaction price allocated to remaining performance obligations under these
agreements. Revenues from royalty license arrangements are recognized either at contract inception when the license is
transferred or when the royalty has been earned, depending on whether the contract contains fixed consideration. Revenues
from stand-alone product sales are recognized at a point in time, when control of the product is transferred to the customer.
Revenues from these types of contracts accounted for 6.5%, 6.5% and 7.8% of revenues for the years ended December 31,
2018, 2017 and 2016, respectively.

On December 31, 2018, the Company had $488.8 million of remaining performance obligations from construction,
engineering and installation services. The Company estimates that approximately $433.3 million, or 88.6%, of the remaining
performance obligations at December 31, 2018 will be realized as revenues in the next 12 months.

Contract Estimates

Accounting for long-term contracts involves the use of various techniques to estimate total contract revenue and costs. For

long-term contracts, the Company estimates the profit on a contract as the difference between the total estimated revenue and
expected costs to complete a contract, and recognizes that profit over the life of the contract. Contract estimates are based on
various assumptions to project the outcome of future events that sometimes span multiple years. These assumptions include
labor productivity and availability; the complexity of the work to be performed; the cost and availability of materials; the
performance of subcontractors; and the availability and timing of funding from the customer.

The Company’s contracts do not typically contain variable consideration or other provisions that increase or decrease the
transaction price. In rare situations where the transaction price is not fixed, the Company estimates variable consideration at
the most likely amount to which it expects to be entitled. The Company includes estimated amounts in the transaction price to
the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty
associated with the variable consideration is resolved. For royalty license agreements, the Company applies the sales-based

and usage-based royalty exception and recognizes royalties at the later of: (i) when the subsequent sale or usage occurs; or (ii)
the satisfaction or partial satisfaction of the performance obligation to which some or all of the sales-or usage-based royalty has
been allocated. For contracts in which a portion of the transaction price is retained and paid after the good or service has been
transferred to the customer, the Company does not recognize a significant financing component. The primary purpose of the
retainage payment is often to provide the customer with assurance that the Company will perform its obligations under the
contract, rather than to provide financing to the customer.

The Company’s estimates of variable consideration and determination of whether to include estimated amounts in the
transaction price are based largely on an assessment of anticipated performance and all information (historical, current and
forecasted) that is reasonably available.

The timing of revenue recognition, billings and cash collections results in billed accounts receivable, contract assets and
contract liabilities on the Consolidated Balance Sheets. Contract assets represent work performed that could not be billed either
due to contract stipulations or the required contractual documentation has not been finalized. Substantially all unbilled
amounts are expected to be billed and collected within one year.

For fixed fee and time-and-materials based contracts, amounts are billed as work progresses in accordance with agreed-
upon contractual terms, either at periodic intervals or upon achievement of contractual milestones. Generally, billing occurs
subsequent to revenue recognition, resulting in contract assets. For some royalty license arrangements, minimum amounts are
billed over the license term as quarterly royalty amounts are determined. This results in contract assets as the Company
recognizes revenue for the license when the license is transferred to the customer at contract inception. The Company’s
contract liabilities consist of advance payments, billings in excess of revenue recognized and deferred revenue.

The Company’s contract assets and contract liabilities are reported in a net position on a contract-by-contract basis at the

end of each reporting period. Advance payments, billings in excess of revenue recognized and deferred revenue are each
classified as current.

Net contract assets (liabilities) consisted of the following (in thousands):

Contract assets – current
Contract liabilities – current (3)

(1) Amounts exclude contract assets of $1.8 million and contract liabilities of less than $0.1 million that were classified as held for sale at

December 31, 2018 (see Note 6).

(2) Amounts exclude contract assets of $1.3 million and contract liabilities of $5.5 million that were classified as held for sale at December

31, 2017 (see Note 6).

(3) Decrease primarily due to the timing of billing and advance deposits received on certain projects in the Company’s coating services

operation in the Middle East.

Included in the change of total net contract assets was a $12.9 million decrease in contract assets, primarily related to the

timing between work performed on open contracts and contractual billing terms, and a $19.3 million decrease in contract
liabilities, primarily related to the timing of customer advances on certain contracts.

Substantially all of the $51.6 million and $62.7 million contract liabilities balances at December 31, 2017 and December

31, 2016, respectively, were recognized in revenues during 2018 and 2017, respectively.

Impairment losses recognized on receivables and contract assets were not material during 2018, 2017 and 2016.

4. RESTRUCTURING

2017 Restructuring

On July 28, 2017, the Company’s board of directors approved the 2017 Restructuring. As part of the 2017 Restructuring,
the Company announced plans to: (i) divest Bayou; (ii) exit all non-pipe related contract applications for the Tyfo® system in
North America; (iii) right-size the cathodic protection services operation in Canada and the CIPP businesses in Australia and
Denmark; and (iv) reduce corporate and other operating costs.

During 2018, the Company’s board of directors approved additional actions with respect to the 2017 Restructuring, which
included the decisions to: (i) divest the Australia and Denmark CIPP businesses; (ii) take actions to further optimize operations
within North America, including measures to reduce consolidated operating costs; and (iii) divest or otherwise exit multiple
additional international businesses, including: (a) the Company’s cathodic protection installation activities in the Middle East,
including Corrpower International Limited, the Company’s cathodic protection materials manufacturing and production joint
venture in Saudi Arabia; (b) United Pipeline de Mexico S.A. de C.V., the Company’s Tite Liner® joint venture in Mexico; (c)
the Company’s Tite Liner® businesses in Brazil and Argentina; (d) Aegion South Africa Proprietary Limited, the Company’s
Tite Liner® and CIPP joint venture in the Republic of South Africa; and (e) the Company’s CIPP contract installation operations
in England.

Total pre-tax 2017 Restructuring and related impairment charges since inception were $139.7 million ($125.9 million post-
tax) and consisted of cash charges totaling $25.8 million and non-cash charges totaling $113.9 million. Cash charges included
employee severance, retention, extension of benefits, employment assistance programs and other restructuring costs associated
with the restructuring efforts described above. Non-cash charges included (i) $86.4 million related to goodwill and long-lived
asset impairment charges recorded in 2017 as part of exiting the non-pipe FRP contracting market in North America, and (ii)
$27.5 million related to allowances for accounts receivable, write-offs of inventory and long-lived assets, impairment of
definite-lived intangible assets, as well as net losses on the disposal of both domestic and international entities. The Company
reduced headcount by approximately 360 employees as a result of these actions.

The Company expects to incur additional cash and non-cash charges of $15 million to $19 million during 2019. The

identified charges are primarily focused in the international operations of both Infrastructure Solutions and Corrosion
Protection, but will also include certain charges in Energy Services to a lesser extent. The Company expects to reduce
headcount by an additional 100 employees as a result of these further actions.

During 2018 and 2017, the Company recorded pre-tax expenses related to the 2017 Restructuring as follows (in

thousands):

Severance and benefit related costs

Lease and contract termination costs

Relocation and other moving costs

On January 4, 2016, the Company’s board of directors approved the 2016 Restructuring to reduce its exposure to the
upstream oil markets and to reduce consolidated expenses. During 2016, the Company completed its restructuring, which
included repositioning Energy Services’ upstream operations in California, reducing Corrosion Protection’s upstream exposure
by divesting its interest in a Canadian pipe coating joint venture, right-sizing Corrosion Protection to compete more effectively
and reducing corporate and other operating costs. The 2016 Restructuring reduced consolidated annual expenses by
approximately $17.4 million, of which approximately $1.2 million, $6.6 million and $5.6 million related to recognized savings
within Infrastructure Solutions, Corrosion Protection and Energy Services, respectively, and $4.0 million related to reduced
corporate costs. Cost savings were achieved primarily through office closures and reducing headcount by 964 employees, or
15.5% of the Company’s total workforce as of December 31, 2015.

The Company recorded total pre-tax charges, most of which were cash charges, of $16.1 million ($10.3 million post-tax) in

connection with the 2016 Restructuring. These charges included employee severance, retention, extension of benefits, early
lease termination and other restructuring costs associated with the restructuring efforts described above.

On May 14, 2018, the Company’s board of directors approved a plan to divest the assets and liabilities of Australia (see
Note 1). The Company is currently in discussions with a third party and management believes that it is probable that a sale will
occur in the first half of 2019.

On July 28, 2017, the Company’s board of directors approved a plan to sell the assets and liabilities of Bayou. The

Company completed a sale transaction during the third quarter of 2018. See Note 1.

The relevant asset and liability balances at December 31, 2018 and 2017 are accounted for as held for sale and measured at

the lower of carrying value or fair value less cost to sell. No impairment charges were recorded on these assets as the net
carrying value approximated or was less than management’s current expectation of fair value less cost to sell. In the event the
Company is unable to sell the assets and liabilities or sells them at a price or on terms that are less favorable, or at a higher cost
than currently anticipated, the Company could incur impairment charges or a loss on disposal.

Financing Arrangements

In October 2015, the Company entered into an amended and restated $650.0 million senior secured credit facility with a
syndicate of banks. In February 2018 and December 2018, the Company amended this facility (the “amended Credit Facility”).
Bank of America, N.A. served as the sole administrative agent and U.S. Bank National Association, PNC Bank, National
Association and Compass Bank acted as co-syndication agents. Merrill Lynch Pierce Fenner & Smith Incorporated, U.S. Bank
National Association, PNC Capital Markets, LLC and Compass Bank acted as joint lead arrangers and joint book managers in
the syndication of the amended Credit Facility.

The amended Credit Facility consists of a $300.0 million five-year revolving line of credit and a $308.4 million five-year

term loan facility. Interest terms from the Company’s original credit facility did not change under the amendment. The
amended Credit Facility also: (i) extended the expiration date of the original credit facility and the amortization period for the
term loan facility from October 2020 to February 2023; (ii) approved the sale of Bayou; and (iii) updated the defined terms to
allow for the add-back of certain charges related to the 2017 Restructuring when calculating the Company’s compliance with
the financial covenants. As required by the amended Credit Facility, net cash proceeds of $35 million from the sale of Bayou
were applied against the outstanding borrowings on the revolving line of credit during 2018. Additionally, and in conjunction
with the sale, the maximum aggregate principal amount of the revolving line of credit was permanently reduced from $300.0
million to $275.0 million.

During 2018, the Company paid expenses of $3.1 million associated with the amended Credit Facility, $1.4 million related
to up-front lending fees and $1.7 million related to third-party arranging fees and expenses, the latter of which was recorded in
“Interest expense” in the Consolidated Statement of Operations in 2018. In addition, the Company had $2.4 million in
unamortized loan costs associated with the original Credit Facility, of which $0.6 million was written off and recorded in
“Interest expense” in the Consolidated Statement of Operations in 2018.

Generally, interest is charged on the principal amounts outstanding under the amended Credit Facility at the British

Bankers Association LIBOR rate plus an applicable rate ranging from 1.25% to 2.25% depending on the Company’s
consolidated leverage ratio. The Company can also opt for an interest rate equal to a base rate (as defined in the credit
documents) plus an applicable rate, which is also based on the Company’s consolidated leverage ratio. The applicable LIBOR
borrowing rate (LIBOR plus Company’s applicable rate) as of December 31, 2018 was approximately 4.45%.

The Company’s indebtedness at December 31, 2018 consisted of $282.2 million outstanding from the $308.4 million term
loan under the amended Credit Facility, $31.0 million on the line of credit under the amended Credit Facility and $1.0 million
of third-party notes and bank debt. During 2018, the Company had net repayments on the line of credit of $7.0 million, which
included a $35.0 million repayment from the proceeds on the Bayou sale, net of borrowings of $28.0 million for domestic
working capital needs.

As of December 31, 2018, the Company had $27.9 million in letters of credit issued and outstanding under the amended

Credit Facility. Of such amount, $12.3 million was collateral for the benefit of certain of our insurance carriers and $15.5
million was for letters of credit or bank guarantees of performance or payment obligations of foreign subsidiaries.

The Company’s indebtedness at December 31, 2017 consisted of $308.4 million outstanding from the term loan under the
Credit Facility, $38.0 million on the line of credit under the Credit Facility and $0.9 million of third-party notes and bank debt.
Additionally, the Company had $7.8 million of debt held by a joint venture (representing funds loaned by its joint venture
partner) listed as held for sale at December 31, 2017 related to the planned sale of Bayou.

At December 31, 2018 and 2017, the estimated fair value of the Company’s long-term debt was approximately $307.7
million and $356.0 million, respectively. Fair value was estimated using market rates for debt of similar risk and maturity and
a discounted cash flow model, which are based on Level 3 inputs as defined in Note 13.

In October 2015, the Company entered into an interest rate swap agreement for a notional amount of $262.5 million, which

is set to expire in October 2020. The notional amount of this swap mirrors the amortization of a $262.5 million portion of the
Company’s $350.0 million term loan drawn from the original Credit Facility. The swap requires the Company to make a
monthly fixed rate payment of 1.46% calculated on the amortizing $262.5 million notional amount, and provides for the
Company to receive a payment based upon a variable monthly LIBOR interest rate calculated on the same amortizing $262.5
million notional amount. The receipt of the monthly LIBOR-based payment offsets a variable monthly LIBOR-based interest
cost on a corresponding $262.5 million portion of the Company’s term loan from the original Credit Facility. After considering
the impact of the interest rate swap agreement, the effective borrowing rate on the Company’s term note as of December 31,
2018 was approximately 3.79%. This interest rate swap is used to partially hedge the interest rate risk associated with the
volatility of monthly LIBOR rate movement and is accounted for as a cash flow hedge. See Note 13.

On March 12, 2018, the Company entered into an interest rate swap forward agreement that begins in October 2020 and
expires in February 2023 to coincide with the amortization period of the amended Credit Facility. The swap will require the
Company to make a monthly fixed rate payment of 2.937% calculated on the then amortizing $170.6 million notional amount,
and provides for the Company to receive a payment based upon a variable monthly LIBOR interest rate calculated on the same
amortizing $170.6 million notional amount. The receipt of the monthly LIBOR-based payment will offset the variable monthly
LIBOR-based interest cost on a corresponding $170.6 million portion of the Company’s term loan from the amended Credit
Facility. This interest rate swap will be used to partially hedge the interest rate risk associated with the volatility of monthly
LIBOR rate movement and accounted for as a cash flow hedge. See Note 13.

The amended Credit Facility is subject to certain financial covenants, including a consolidated financial leverage ratio and

consolidated fixed charge coverage ratio. Subject to the specifically defined terms and methods of calculation as set forth in
the amended Credit Facility’s credit agreement, the financial covenant requirements, as of each quarterly reporting period end,
are defined as follows:

• Consolidated financial leverage ratio, as amended, compares consolidated funded indebtedness to amended Credit

Facility defined income with a maximum amount not to exceed 3.5 to 1.00. At December 31, 2018, the Company’s
consolidated financial leverage ratio was 2.94 to 1.00 and, using the amended Credit Facility defined income, the
Company had the capacity to borrow up to $61.6 million of additional debt.

• Consolidated fixed charge coverage ratio, as amended, compares amended Credit Facility defined income to amended

Credit Facility defined fixed charges with a minimum permitted ratio of not less than 1.25 to 1.00. At December 31,
2018, the Company’s fixed charge ratio was 1.42 to 1.00.

At December 31, 2018, the Company was in compliance with all of its debt and financial covenants as required under the

amended Credit Facility.

9. STOCKHOLDERS’ EQUITY

Share Repurchase Plan

In October 2017, the Company’s board of directors authorized the open market repurchase of up to $40.0 million of the
Company’s common stock to be made during 2018. That authorization was reduced to $30 million in 2018 in connection with
the execution of the amended Credit Facility. The Company began repurchasing shares under this program in January 2018. In
December 2018, the Company’s board of directors authorized the open market repurchase of up to two million shares of the
Company’s common stock. The program did not establish a time period in which the repurchases had to be made. In
December 2018, the Company amended its Credit Facility, which limits the open market share repurchases to $32.0 million for
2019. Once repurchased, the Company promptly retires such shares.

The Company is also authorized to repurchase up to $10.0 million of the Company’s common stock in each calendar year

in connection with the Company’s equity compensation programs for employees. The participants in the Company’s equity
plans may surrender shares of common stock in satisfaction of tax obligations arising from the vesting of restricted stock and
restricted stock unit awards under such plans and in connection with the exercise of stock option awards. The deemed price
paid is the closing price of the Company’s common stock on The Nasdaq Global Select Market on the date that the restricted
stock or restricted stock unit vests or the shares of the Company’s common stock are surrendered in exchange for stock option
exercises. With regard to stock option awards, the option holder may elect a “net, net” exercise in connection with the exercise
of employee stock options such that the option holder receives a number of shares equal to the built-in gain in the option shares
divided by the market price of the Company’s common stock on the date of exercise, less a number of shares equal to the taxes
due upon the exercise of the option divided by the market price of the Company’s common stock on the date of exercise. The
shares of Company common stock surrendered to the Company for taxes due on the exercise of the option are deemed
repurchased by the Company.

During 2018, the Company acquired 949,464 shares of the Company’s common stock for $20.3 million ($21.36 average

price per share) through the open market repurchase programs discussed above and 228,068 shares of the Company’s common
stock for $5.5 million ($24.08 average price per share) in connection with the satisfaction of tax obligations in connection with
the vesting of restricted stock and restricted stock units. Once repurchased, the Company immediately retired all such shares.
During 2018, the Company did not acquire any of the Company’s common stock in connection with “net, net” exercises of
employee stock options.

During 2017, the Company acquired 1,599,093 shares of the Company’s common stock for $35.3 million ($22.10 average

price per share) through open market repurchase programs and 112,899 shares of the Company’s common stock for $2.5
million ($22.15 average price per share) in connection with the satisfaction of tax obligations in connection with the vesting of
restricted stock and restricted stock units. Once repurchased, the Company immediately retired all such shares. During 2017,
the Company did not acquire any of the Company’s common stock in connection with “net, net” exercises of employee stock
options.

During 2016, the Company acquired 2,226,875 shares of the Company’s common stock for $41.8 million ($18.76 average
price per share) through open market repurchase programs and 61,039 shares of the Company’s common stock for $1.2 million
($19.65 average price per share) in connection with the satisfaction of tax obligations in connection with the vesting of
restricted stock and restricted stock units. In addition, during 2016, the Company acquired 61,980 shares of the Company’s
common stock in connection with “net, net” exercises of employee stock options for a gross value of $1.5 million ($1.2 million
in cash value). Once repurchased, the Company immediately retired all such shares.

Equity-Based Compensation Plans

Employee Plans

In April 2016, the Company’s stockholders approved the 2016 Employee Equity Incentive Plan, which was amended in
2017 by the First Amendment to the 2016 Employee Equity Incentive Plan (as amended, the “2016 Employee Plan”). In April
2018, the Company’s stockholders approved the Second Amendment to the 2016 Employee Equity Incentive Plan, which
increased by 1,700,000 the number of shares of the Company’s common stock reserved and available for issuance in
connection with awards issued under the 2016 Employee Plan. The 2016 Employee Plan, which replaced the 2013 Employee
Equity Incentive Plan, provides for equity-based compensation awards, including restricted shares of common stock,
performance awards, stock options, stock units and stock appreciation rights. The 2016 Employee Plan is administered by the
compensation committee of the board of directors, which determines eligibility, timing, pricing, amount and other terms or
conditions of awards. As of December 31, 2018, 2,749,367 shares of the Company’s common stock were available for issuance
under the 2016 Employee Plan.

Prior to the 2016 Employee Plan, the board of directors administered the 2013 Employee Equity Incentive Plan (the “2013

Employee Plan”) and the 2009 Employee Equity Incentive Plan (the “2009 Employee Plan”). At December 31, 2018, there
were no options and 412,327 unvested shares of restricted stock and restricted stock units outstanding under the 2013
Employee Plan, and 52,783 options and no unvested shares of restricted stock and restricted stock units outstanding under the
2009 Employee Plan.

Director Plans

In April 2016, the Company’s stockholders also approved the 2016 Non-Employee Director Equity Incentive Plan (the

“2016 Director Plan”), which replaced the 2011 Non-Employee Director Equity Incentive Plan. The 2016 Director Plan
provides for equity-based compensation awards, including non-qualified stock options and stock units. The board of directors
administers the 2016 Director Plan and has the authority to establish, amend and rescind any rules and regulations related to the
2016 Director Plan. As of December 31, 2018, 71,580 shares of the Company’s common stock were available for issuance
under the 2016 Director Plan.

Prior to the 2016 Director Plan, the board of directors administered the 2011 Non-Employee Director Equity Plan (“2011
Director Plan”), the 2006 Non-Employee Director Equity Plan (“2006 Director Plan”) and the 2001 Non-Employee Director
Equity Plan (“2001 Director Plan”), all of which contained substantially the same provisions as the current plan. At
December 31, 2018, there were 91,058 deferred stock units outstanding under the 2011 Director Plan, 46,841 deferred stock
units outstanding under the 2006 Director Plan and 54,575 deferred stock units outstanding under the 2001 Director Equity
Plan.

Activity and related expense associated with these plans are described in Note 10.

10. EQUITY-BASED COMPENSATION

Stock Awards

Stock awards, which include shares of restricted stock, restricted stock units and performance stock units, are awarded
from time to time to executive officers and certain key employees of the Company. Stock award compensation is recorded
based on the award date fair value and charged to expense ratably through the requisite service period. The forfeiture of
unvested restricted stock, restricted stock units and performance stock units causes the reversal of all previous expense
recorded as a reduction of current period expense.

Expense associated with stock awards was $6.8 million, $9.0 million and $9.1 million in 2018, 2017 and 2016,
respectively. Unrecognized pre-tax expense of $9.9 million related to stock awards is expected to be recognized over the
weighted average remaining service period of 2.4 years for awards outstanding at December 31, 2018.

Deferred Stock Unit Awards

Deferred stock units generally are awarded to directors of the Company and represent the Company’s obligation to transfer

one share of the Company’s common stock to the grantee at a future date and generally are fully vested on the date of grant.

On December 22, 2017, the U.S. government enacted the TCJA, which includes significant changes to the U.S. corporate

income tax system including: (i) a federal corporate rate reduction from 35% to 21%; (ii) limitations on the deductibility of
interest expense and executive compensation; (iii) creation of new minimum taxes such as the Global Intangible Low Taxed
Income (“GILTI”) tax and the base erosion anti-abuse tax (“BEAT”); and (iv) the transition of U.S. international taxation from
a worldwide tax system to a modified territorial tax system, which resulted in a one time U.S. tax liability on those earnings
that have not previously been repatriated to the U.S. Beginning in 2018, the Company no longer records U.S. federal income
tax on its share of income from foreign subsidiaries and no longer records a benefit for foreign tax credits related to that
income.

In its reporting since the TCJA was enacted, the Company had been recording provisional amounts for certain enactment-
date effects of the TCJA by applying the guidance in SAB 118 because the enactment-date accounting for these effects had not
yet been completed. In 2018 and 2017, the Company recorded a net tax expense related to the enactment-date effects of the
TCJA that included recording the one-time transition tax liability related to undistributed earnings of certain foreign
subsidiaries that were not previously taxed and adjusting deferred tax assets and liabilities for the changes in the federal tax
rate.

The one-time transition tax is based on total post-1986 earnings and profits (“E&P”) that were previously deferred from
U.S. income taxes. The tax is based on the amount of those earnings held in cash and other specified assets, either at the end of
2017 or the average of the year end balances for 2015 and 2016. Based on the Company’s initial analysis of the TCJA in 2017,
it recorded a provisional estimated net tax expense of $2.4 million, which consisted of a charge of $10.4 million for the deemed
mandatory repatriation, and reduced by a $7.1 million release of a deferred tax liability on unremitted foreign earnings and $0.9
million of other TCJA related impacts. Upon further analysis of the TCJA and notices and regulations issued and proposed by
the U.S. Department of the Treasury and the Internal Revenue Service (“IRS”), the Company finalized its calculations of the
transition tax liability during 2018. Adjustments included further refinement of computations related to earnings and profits,
cash and cash equivalents, state income tax and foreign withholding taxes pursuant to guidance issued during the year. The
final transition tax liability consisted of a charge of $9.6 million for the deemed mandatory repatriation, and reduced by the
$7.1 million release of a deferred tax liability on unremitted foreign earnings and $2.0 million of other TCJA related impacts.
The Company decreased its December 31, 2017 provisional amount by $1.9 million during 2018, which is included as a
component of income tax expense.

The transition tax liability, as filed on the 2017 federal income tax return and after utilization of foreign tax credits, was
$5.2 million. Although Congressional intent and the statutory language were clear that the transition tax could be paid over a
period of eight years, and the Company properly elected to pay the transition tax liability over a period of eight years, IRS
guidance published in April 2018 indicated that taxpayers in a net overpayment position would have all overpayments first
applied to successive installments of the transition tax liability. Legislative proposals were passed in the U.S. House of
Representatives in late December 2018 to correct the application of this IRS guidance; however there has been no action in the
U.S. Senate to pass legislation addressing this issue. As a result of the overpayment from 2017 and the anticipated utilization
of 2018 foreign tax credits, no further tax payments related to the transition tax will be required.

The Company’s deferred tax assets at December 31, 2018 included $22.9 million in federal, state and foreign net operating

loss (“NOL”) carryforwards. These NOLs include $14.3 million, which if not used will expire between the years 2019 and
2038, and $8.6 million that have no expiration dates. The Company also has deferred tax amounts related to foreign tax credit
carryforwards of $0.5 million, of which, $0.4 million will expire in 2026 if not used and $0.1 million have no expiration date.

For financial reporting purposes, a valuation allowance of $28.5 million has been recognized to reduce the deferred tax

assets related to certain federal, state and foreign net operating loss carryforwards and other assets, for which it is more likely
than not that the related tax benefits will not be realized, due to uncertainties as to the timing and amounts of future taxable
income. The valuation allowance at December 31, 2017 was $29.8 million.

As of December 31, 2018, a valuation allowance has been recorded to record only the portion of the deferred tax asset that
is more likely than not to be realized. The amount of the deferred tax asset considered realizable; however, could be adjusted if
estimates of future taxable income during the carryforward period are reduced or increased or if objective negative evidence in
the form of cumulative losses is no longer present and additional weight may be given to subjective evidence such as our
projections for growth.

As a result of the deemed mandatory repatriation provisions in the TCJA, the Company included $206.7 million of

undistributed earnings in income subject to U.S. tax at reduced tax rates. Certain provisions within the TCJA effectively
transition the U.S. to a territorial system and eliminates deferral on U.S. taxation for certain amounts of income that are not
taxed at a minimum level. At this time, the Company does not intend to distribute earnings in a taxable manner; and therefore,
intends to limit distributions to: (i) earnings previously taxed in the U.S.; (ii) earnings that would qualify for the 100 percent
dividends received deduction provided in the TCJA; or (iii) earnings that would not result in significant foreign taxes. As a
result, the Company has not recognized a deferred tax liability on any remaining undistributed foreign earnings as of December
31, 2018.

FASB ASC 740, Income Taxes (“FASB ASC 740”), prescribes a more-likely-than-not threshold for the financial statement

recognition and measurement of a tax position taken or expected to be taken in a tax return. FASC ASC 740 also provides
guidance on de-recognition, classification, interest and penalties, accounting in interim periods and disclosure of uncertain tax
positions in financial statements.

The total amount of unrecognized tax benefits, if recognized, that would affect the effective tax rate was $0.4 million at

December 31, 2018.

The Company recognizes interest and penalties, if any, related to unrecognized tax benefits in income tax expense. During

the years ended December 31, 2018, 2017 and 2016, approximately $0.2 million, $0.3 million and $0.3 million, respectively,
was expensed for interest and penalties.

The Company believes that it is reasonably possible that the total amount of unrecognized tax benefits will change in 2018.

The Company has certain tax return years subject to statutes of limitation that will expire within twelve months. Unless
challenged by tax authorities, the expiration of those statutes of limitation is expected to result in the recognition of uncertain
tax positions in the amount of approximately $0.8 million.

The Company is subject to taxation in the United States, various states and foreign jurisdictions. With few exceptions, the

Company is no longer subject to U.S. federal, state, local or foreign examinations by tax authorities for years before 2014.

12. COMMITMENTS AND CONTINGENCIES

Leases

The Company leases a number of its administrative and operations facilities under non-cancellable operating leases
expiring at various dates through 2025. In addition, the Company leases certain construction, automotive and computer
equipment on a multi-year, monthly or daily basis. Rental expense in the years ended December 31, 2018, 2017 and 2016 was
$26.2 million, $26.7 million and $23.8 million, respectively.

Litigation

In December 2016, the Company settled two lawsuits related to the December 2012 departure of several key leaders in
sales and operations for the Tyfo® technology, which is part of the Infrastructure Solutions platform. Under the settlement,
Aegion will receive $6.6 million over four years; and accordingly, recorded the gain to “Gain on litigation settlement” in the
Consolidated Statement of Operations. The initial $3.6 million cash payment was received in December 2016, with the
remainder to be paid in $750,000 annual installments over the following four years. At December 31, 2018, $750,000 was
recorded to “Prepaid expenses and other current assets” and $1.5 million was recorded to “Other assets” in the Consolidated
Balance Sheet.

101

The Company is involved in certain litigation incidental to the conduct of its business and affairs. Management, after
consultation with legal counsel, does not believe that the outcome of any such litigation, individually or in the aggregate, will
have a material adverse effect on the Company’s consolidated financial condition, results of operations or cash flows.

Contingencies

In connection with the Brinderson acquisition, certain pre-acquisition matters were identified in 2014 whereby a loss is
both probable and reasonably estimable. The Company establishes liabilities in accordance with FASB ASC Subtopic No.
450-20, Contingencies - Loss Contingencies, and accordingly, recorded an accrual related to various legal, tax, employee
benefits and employment matters. At December 31, 2016, the accrual relating to these matters was $6.0 million. During 2017,
the Company made a $0.3 million payment related to one of the above matters. Additionally, the Company reassessed its
reserve during 2017 for: (i) the lapse of certain payroll tax statutory limitation periods; and (ii) further developments in the
legal status of these matters, including the preliminary settlement through mediated resolution of several matters. Following
consultation with internal and third-party legal and tax counsel, the Company lowered its accrual for such matters by $1.5
million during 2017. The accrual adjustments resulted in an offset to “Operating expense” in the Consolidated Statement of
Operations. During 2018, the Company made an additional $0.2 million payment related to one of the above matters. As of
December 31, 2018, the remaining accrual relating to these matters was $4.0 million.

Purchase Commitments

The Company had no material purchase commitments at December 31, 2018.

Guarantees

The Company has many contracts that require the Company to indemnify the other party against loss from claims,

including claims of patent or trademark infringement or other third party claims for injuries, damages or losses. The Company
has agreed to indemnify its surety against losses from third-party claims of subcontractors. The Company has not previously
experienced material losses under these provisions and, while there can be no assurances, currently does not anticipate any
future material adverse impact on its consolidated financial position, results of operations or cash flows.

The Company regularly reviews its exposure under all its engagements, including performance guarantees by contractual
joint ventures and indemnification of its surety. As a result of the most recent review, the Company has determined that the risk
of material loss is remote under these arrangements and has not recorded a liability for these risks at December 31, 2018 on its
consolidated balance sheet.

Retirement Plans

Approximately 1,100 of our U.S. employees participate in multi-employer retirement plans. Substantially all of the
Company’s remaining U.S. employees are eligible to participate in one of the Company’s sponsored defined contribution
savings plans, which are qualified plans under the requirements of Section 401(k) of the Internal Revenue Code. Company
contributions to the domestic plans were $5.7 million, $6.3 million and $5.5 million for the years ended December 31, 2018,
2017 and 2016, respectively.

Certain foreign subsidiaries maintain various other defined contribution retirement plans. Company contributions to such

plans for the years ended December 31, 2018, 2017 and 2016 were $1.1 million, $1.0 million and $0.8 million, respectively.

In connection with the Company’s 2009 acquisition of Corrpro, the Company assumed an obligation associated with a
contributory defined benefit pension plan sponsored by a subsidiary of Corrpro located in the United Kingdom. Employees of
this Corrpro subsidiary no longer accrue benefits under the plan; however, Corrpro continues to be obligated to fund prior
period benefits. Both the pension expense and funding requirements for the years ended December 31, 2018, 2017 and 2016
were immaterial to the Company’s consolidated financial position and results of operations. The benefit obligation and plan
assets at December 31, 2018 were approximately $7.1 million and $7.9 million, respectively. The Company used a discount
rate of 2.8% for the evaluation of the pension liability. The Company recorded an asset associated with the overfunded status
of this plan of approximately $0.8 million, which is included in other long-term assets on the consolidated balance sheet. The
benefit obligation and plan assets at December 31, 2017 approximated $7.5 million and $9.3 million, respectively. Plan assets
consist of investments in equity and debt securities as well as cash, which are primarily Level 2 inputs as defined in Note 13.

13. DERIVATIVE FINANCIAL INSTRUMENTS

As a matter of policy, the Company uses derivatives for risk management purposes, and does not use derivatives for
speculative purposes. From time to time, the Company may enter into foreign currency forward contracts to hedge foreign
currency cash flow transactions. For cash flow hedges, gain or loss is recorded in the Consolidated Statements of Operations

102

upon settlement of the hedge. All of the Company’s hedges that are designated as hedges for accounting purposes were highly
effective; therefore, no notable amounts of hedge ineffectiveness were recorded in the Company’s Consolidated Statements of
Operations for either the settlement of cash flow hedges or the outstanding hedged balance. At December 31, 2018 and 2017,
the Company’s cash flow hedges were in a net deferred gain position of $1.8 million and $3.2 million, respectively, due to
favorable movements in short-term interest rates relative to the hedged position. The Company presents derivative instruments
in the consolidated financial statements on a gross basis. Deferred gains and losses were recorded in other non-current assets
and other non-current liabilities, respectively, and other comprehensive income on the Consolidated Balance Sheets. The net
periodic change of the Company’s cash flow hedges was recorded on the foreign currency translation adjustment and derivative
transactions line of the Consolidated Statements of Equity.

The Company also engages in regular inter-company trade activities and receives royalty payments from certain of its
wholly-owned entities, paid in local currency, rather than the Company’s functional currency, U.S. Dollars. The Company
utilizes foreign currency forward exchange contracts to mitigate the currency risk associated with the anticipated future
payments from certain of its international entities. During 2018, 2017 and 2016, losses of $0.5 million, $0.1 million and $0.1
million, respectively, were recorded upon settlement of foreign currency forward exchange contracts. Gains and losses of this
nature are recorded to “Other income (expense)” in the Consolidated Statements of Operations.

In October 2015, the Company entered into an interest rate swap agreement for a notional amount of $262.5 million, which

is set to expire in October 2020. The notional amount of this swap mirrors the amortization of a $262.5 million portion of the
Company’s $350.0 million term loan drawn from the original Credit Facility. The swap requires the Company to make a
monthly fixed rate payment of 1.46% calculated on the amortizing $262.5 million notional amount and provides for the
Company to receive a payment based upon a variable monthly LIBOR interest rate calculated by amortizing the $262.5 million
same notional amount. The receipt of the monthly LIBOR-based payment offsets a variable monthly LIBOR-based interest
cost on a corresponding $262.5 million portion of the Company’s term loan from the original Credit Facility. This interest rate
swap is used to partially hedge the interest rate risk associated with the volatility of monthly LIBOR rate movement and is
accounted for as a cash flow hedge.

FASB ASC 820, Fair Value Measurements (“FASB ASC 820”), defines fair value and establishes a framework for
measuring and disclosing fair value instruments. The guidance establishes a three-tier fair value hierarchy, which prioritizes
the inputs used in measuring fair value. These tiers include:

• Level 1 – defined as quoted prices in active markets for identical instruments;

• Level 2 – defined as inputs other than quoted prices in active markets that are either directly or indirectly observable;

• Level 3 – defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to

develop its own assumptions.

In accordance with FASB ASC 820, the Company determined that the value of all of its derivative instruments, which are

measured at fair value on a recurring basis, are derived from significant observable inputs, referred to as Level 2 inputs.

The Company had no transfers between Level 1, 2 or 3 inputs during the quarter ended December 31, 2018. Certain
financial instruments are required to be recorded at fair value. Changes in assumptions or estimation methods could affect the
fair value estimates; however, the Company does not believe any such changes would have a material impact on its financial
condition, results of operations or cash flows. Other financial instruments including cash and cash equivalents and short-term
borrowings, including notes payable, are recorded at cost, which approximates fair value, which is based on Level 2 inputs as
previously defined.

14. SEGMENT AND GEOGRAPHIC INFORMATION

The Company has three operating segments, which are also its reportable segments: Infrastructure Solutions; Corrosion
Protection; and Energy Services. The Company’s operating segments correspond to its management organizational structure.
Each operating segment has leadership that reports to the chief operating decision manager (“CODM”). The operating results
and financial information reported by each segment are evaluated separately, regularly reviewed and used by the CODM to
evaluate segment performance, allocate resources and determine management incentive compensation.

The following disaggregated financial results have been prepared using a management approach that is consistent with the

basis and manner with which management internally disaggregates financial information for the purpose of making internal
operating decisions. The Company evaluates performance based on stand-alone operating income (loss), which includes
acquisition and divestiture expenses, restructuring charges and an allocation of corporate-related expenses.
