Letter from Jack A. Blossman, Jr. | Chairman of the Board of Directors
2021 was an incredible year 
of growth for Charah Solutions 
with strong year-over-year 
revenue increases, expanded 
partnerships with new and 
existing utility customers, and 
a third straight year of record 
new business awards. The 
Charah Solutions Board is very 
pleased with the significant accomplishments achieved 
in our fourth year as a public company and even more 
excited about the growth that is in store for the Company 
in the near term. The expansion in our customer base 
of utility and power generation customers around the 
country and of our integrated services embedded at the 
customer level, combined with recent positive legislative 
and regulatory action at the state and federal levels, 
position the Company very well for accelerated growth 
and continued industry leadership resulting in increased 
financial performance for many years to come.
As the newly elected Board Chairman, I am confident 
in the growth strategy being led by President and CEO 
Scott Sewell and CFO and Treasurer Roger Shannon, and 
I am very proud of the implementation and hard work of 
our field employees and management teams across the 
country. Charah Solutions is truly one of America’s best 
examples of resource conservation and recovery. Through 
the environmental remediation of coal-fired power 
plants, land, and ash pond impoundments, we are able to 
recycle coal ash used in the production of green concrete 
that would otherwise be sent to landfills while also 
redeveloping land to benefit the community. We continue 
to grow our core Remediation and Compliance Services 
business while making successful and significant inroads 
into new business segments with our Environmental Risk 
Transfer (ERT) services business, which has proven to be 
a very important asset for the future of our industry and 
the Company. 
Industry-leading innovation and technology are key drivers 
for the Company, as they have been since our inception, 
with our proprietary EnviroSource™ fly ash beneficiation 
technology providing a superior product to the market at 
a lower cost while preserving our natural resources, and 
reducing CO2 emissions.
Charah Solutions continues to take a leadership role 
in fulfilling our Environmental, Social and Governance 
(ESG) commitments for the betterment of our planet, 
our communities, our customers, our employees, and 
our shareholders. These priorities will only increase in 
relevance for all companies as regulatory agencies work 
to standardize climate-related disclosures for investors. 
We strive to be at the forefront of this reporting while 
providing services that truly benefit the environment 
as well as actions and goals that improve the lives of 
our employees and provide opportunities for increased 
diversity in our industry. Our recent 2021 ESG Report 
shows our true commitment with 1-year goals results 
that are driving real change and benefits for not only the 
environment but for our employees and the communities 
in which we work. 
2021 saw many successes for Charah Solutions 
from a business and financial perspective that will 
allow the Company to continue to capitalize on its 
industry leadership position as well as current market 
conditions into the future. Our deep Board experience 
across the power generation industry, combined with 
our management team’s unparalleled knowledge of 
operations, our diversified customer base, our broad 
spectrum of service offerings, and our industry-leading 
safety record position us well for increased financial 
and market share growth. We remain committed to 
creating exceptional and sustainable value for all of our 
shareholders today and for years to come. Thank you for 
your investment in Charah Solutions.

Most recently, in January 2022, the U.S. Environmental 
Protection Agency (EPA) acted to expand and 
strengthen the regulation for coal ash and groundwater 
management of regulatorily mandated surface 
impoundments and landfills, marking the first time the 
EPA has enforced the 2015 Coal Combustion Residuals 
Regulation from coal-fired power plants for the 
management of ash impoundments and landfills.
All of this progress comes with an enhanced focus 
on ESG as we strive to be the best possible employer 
to our team members, be vigilant stewards of the 
environment, deliver value to our shareholders, and give 
back to the communities in which we work and live. We 
recently published our second annual 2021 ESG report, 
and I am very proud to state that we substantially 
achieved all our 1-year ESG goals,  and are well on our 
way to meeting our 3-year and 5-year goals due to the 
hard work and dedication of our employees at our sites 
across the country. Sustainability is integral to what 
we do and has been part of our DNA since the start. 
We support the SEC’s push to establish uniform ESG 
reporting standards and believe that all corporations 
should do their part and be held accountable to ESG 
measures.
We also made major progress in 2021 by “doubling 
down” on our sustainability commitments through the 
dramatic growth of our ERT business. We announced 
the acquisition of GenOn Energy’s Avon Lake and 
Cheswick Generating Stations, where we plan to shutter 
these plants and perform sustainable environmental 
remediation and redevelopment. We expect to place 
thousands of acres of land back into public and private 
use. Importantly, we completed the sale of 80% of 
the real property acreage at our Gibbons Creek ERT 
project in late 2021, and we announced the sale of the 
remaining 20% of the acreage in March 2022.
These business wins and favorable market conditions 
provide additional growth opportunities to expand our 
already broad platform of services, which creates  
efficiencies at the customer level by sourcing multiple 
services from a single trusted partner, a key Charah 
Solutions differentiator. This includes opportunities for 
the installation of our EnviroSource fly ash beneficiation 
technology, where we expect to complete our first 
commercial agreement in the first half of 2022, 
providing a significantly lower cost profile technology 
to the market versus competing technologies. We 
currently have more than $3.1 billion of pending 
proposals, and we have identified nearly $7.5 billion of 
2022 will mark the 35th 
Anniversary of Charah 
Solutions and a major 
milestone in our Company’s 
history as we celebrate our 
commitment to living the 
Charah Solutions mission, 
vision and values each day 
our team comes to work: 
holding each other accountable, exceeding customer 
expectations, never compromising, rethinking the 
routine, and taking action. As we reflect on 2021, 
I want to start by thanking our leadership team 
and employees for their dedication as they deliver 
Service Above All for our customers to improve the 
environment, enhance our communities, and make 
Charah Solutions a great place to work. 
2021 was a highly successful year for Charah 
Solutions not only in terms of financial results as we 
achieved strong year-over-year growth in revenues, 
but also in the manner in which the entire Charah 
Solutions team came together to fully overcome 
pandemic challenges while growing our business to 
record-setting levels. It was yet another incredible 
year for us with $840 million in new business 
awards, a 17.5% increase from our previous record 
of $715 million in 2020. We won more new business 
in 2021 than ever before while expanding our 
customer base to include new customers such as 
NV Energy, Mosaic, Associated Electric Cooperative, 
NIPSCO, and OG&E, as well as expanding our service 
footprint with new projects in Nevada and Oklahoma. 
We expect these new awards to result in double-digit 
revenue growth in 2022.
We also saw significant legislative and regulatory 
action in 2021 and early 2022. We believe these 
actions provide enhanced opportunities for us 
to continue to grow our core business. The U.S. 
rejoined the Paris Climate Agreement and is making 
commitments to 100% clean electricity by 2035. In 
November 2021, the Infrastructure Investment and 
Jobs Act became law, which provides increased 
opportunities for fly ash to be recycled and 
beneficially used in the production of green concrete 
to meet the growing infrastructure demand.

Charah Solutions’ fly ash improves concrete durability, 
strength, mixability, and finish. This concrete is used to build 
infrastructure to keep the economy moving.
CCRs are generated by burning pulverized coal in 
a boiler furnace which creates both bottom ash 
and fly ash. Bottom ash is mechanically collected 
at the bottom of the boiler furnace, whereas 
fly ash is captured by routing flue gas through 
electrostatic precipitators. The final process is flue 
gas desulfurization (FGD), creating synthetic gypsum. 
All processes create byproducts which are managed 
by Charah Solutions and can be beneficially used 
through sustainable processes.

OVER 4.79 MILLION TONS OF CO2 
FROM ENTERING THE ATMOSPHERE
through beneficial use of ash and shutdown 
of coal-fired power plants.

There have been several major legislative and regulatory 
announcements at the federal and state levels in the last 
year that we believe accelerate our business opportunities 
and position Charah Solutions to leverage existing 
capabilities, technologies, and customer relationships to 
provide vertically integrated offerings to some of the 
largest utilities and concrete producers in the country.
  In November 2021, the Infrastructure Investment 
and Jobs Act was signed into law, which provides 
increased opportunity for fly ash to be recycled and 
beneficially used in the production of green concrete to 
meet the growing infrastructure demand in the ready 
mix concrete market, providing an environmentally-
conscious replacement for Portland cement in the 
production of ready mix concrete and concrete 
products. 
  Most recently, in January 2022, the EPA took action, 
expanding and strengthening the regulation for coal 
ash and groundwater management of regulatorily 
mandated surface impoundments and landfills, 
marking the first time the EPA has enforced the 
2015 Coal Combustion Residuals Regulation from 
coal-fired power plants for the management of ash 
impoundments and landfills. 
These are major steps that impact the full remediation 
of approximately 1,000 regulatorily mandated coal 
ash surface impoundments and landfills, protecting 
groundwater and providing the opportunity for these 
remediated lands to benefit both the communities and 
the environment. Utilities are under increasing pressure 
to manage coal plant byproducts in ways that do not 
harm the environment and to close legacy ash ponds that 
present a significant environmental burden.
According to the Energy Information Administration (EIA), 
between 2010 and the first quarter of 2019, U.S. power 
companies announced the retirement of more than 546 
coal-fired power plants, totaling approximately 102 GW 
of generating capacity. There are plans to retire another 
17 GW of coal-fired capacity by 2025.
Charah Solutions is well-positioned to continue to thrive, 
and we believe these recent announcements will accelerate 
services growth under multiple scenarios for the future 
of coal-fired power plants. While the long-term future of 
coal-fired power plants remains to be fully seen, we now 
have clear direction at both the federal and state levels, 
which seem to indicate coal-fired power plants being 
decommissioned at the expected steady rate as well as 
an acceleration of remediation for the approximately 1,000 
regulatorily mandated coal ash surface impoundments 
and landfills. We believe that Charah Solutions’ services 
will continue to be in high demand and will most likely be 
needed even more in the future than currently projected, 
serving our utility partners for many years to come.
Accelerated Decommission Scenario
Under the scenario where the approximately 240 
currently existing coal-fired power plants in the U.S. are 
decommissioned at an accelerated rate over the next 10 to 
15 years, the shutdown of these plants and the remediation 
required at the federal EPA and local and state levels would 
mean an overall increase in our routine ash management 
remediation opportunities as well as an increase in demand 
for many of our other services, including:
  Increased demand for our ERT services, where we 
provide innovative turnkey solutions for these large-scale, 
complex environmental projects, including the acquisition 
of the property, shutdown, decommissioning, and the 
demolition of the coal-fired power plant, remediation of 
the onsite ash ponds and landfills, and restoration of the 
land. A typical ERT project is 2 to 5 years in duration.

  Recent EPA announcements regarding enforcement 
of the 2015 Coal Combustion Residuals Regulation 
from coal-fired power plants for the management 
of ash impoundments and landfills mean increased 
demand for remediation of the more than 1,000 
regulatorily mandated surface impoundments in the U.S., 
potentially accelerating our business growth vs. current 
expectations. As a result, we expect to see remediation 
and compliance activity greatly increase.
  The November 2021 Infrastructure Investment and Jobs 
Act will accelerate our byproducts recycling business 
and continue to drive a much needed influx for:
     – The byproducts and fly ash we market to concrete 
and cement producers around the country for 
beneficial use in the production of Portland cement 
and green concrete, as there is currently a shortage 
in the market today.
    – An increase in the amount of reclaimed ponded ash 
that we could recycle and market to cement kiln feed 
producers.
    – An increase in the amount of gypsum that we 
could handle and beneficially market to drywall 
manufacturers.
    – An increase in the amount of conditioned ash that 
would be immediately available for use in large-scale 
structural fill projects where the land is reclaimed and 
used for community or business use.
  Expected high demand for our proprietary EnviroSource 
fly ash beneficiation technology, which makes unusable 
fly ash stored in ponds or landfills immediately 
marketable. As many state and local regulations are 
mandating that a percentage of the ash in pond and 
landfill closure projects has to be beneficially used, this 
would provide many years of ongoing ash beneficiation 
projects and would create a 10 to 15 year supply 
of Class C and Class F fly ash that we would sell to 
concrete producers for green concrete.
Base Decommission Scenario
Under a base scenario where the life of existing coal-fired power 
plants in the U.S. remains on track with today’s estimates of 
steady shutdowns over the next 20 to 30 years or these lifecycles 
are extended beyond current predictions, Charah Solutions is 
well-positioned for increased business and revenue opportunities 
with a steady stream of large scale pond and landfill remediation, 
ERT, and byproduct recycling projects given regulatorily mandated 
surface impoundment remediation needs as well as the ongoing 
need for our ash management services. In this scenario, a larger 
portion of the overall services we provide to our utility partners 
would be expected to be in play for a more extended period, 
leading to increased business, including:
  An uptick in the need for our ERT services as plants will be 
decommissioned over this 20 to 30-year period, likely led by 
independent power producer closures and shutdown of less 
efficient plants in the near term.
  An ongoing stream of additional business in the marketing of 
byproducts and supplementary cementitious materials (SCMs) 
as plants remain open for the predicted or longer time. 
  Potential high demand for our proprietary EnviroSource fly ash 
beneficiation technology as many state and local regulations 
are mandating that a percentage of the ash in pond and landfill 
closure projects be recycled. 
  Under this scenario, our strategic planning and the needs for 
our services play out much like we have seen our business 
unfold in the last 12 to 18 months. Namely, increased demand 
for our broad platform of services due to the need for utilities 
to meet federal and state environmental regulations across the 
U.S. drives the needs of electric utilities for larger and more 
complex remediation solutions, with increased size and scope 
of projects. 
It is also important to note that there are over 6,000 coal-fired 
power plants in operation outside of the U.S., over 350 currently 
under construction outside of the U.S., and another 1,000+ outside 
of the U.S. that have been permitted for construction. Charah 
Solutions’ leadership and expertise as a provider of environmental 
remediation and compliance services and byproduct recycling to 
the power generation industry makes us well positioned to expand 
our services outside of the U.S. and to take advantage of these 
markets where coal-fired power plants are expanding.

11
For 2022 and beyond, we see continued strong 
and growing interest among our existing and 
potential power generation customers for the 
environmental solutions we provide, particularly 
within our Remediation and Compliance Services, 
Byproduct Services, and ERT business lines. We are 
optimistic that we will reach our first commercial 
agreement for the use of our EnviroSource fly ash 
beneficiation technology in the first half of 2022. We 
continue to have a substantial amount of pending 
and anticipated bids for new business across all 
of our business lines as our utility customers work 
to address their federally and state-mandated 
remediation requirements. We currently have more 
than $3.1 billion in pending proposals, and we have 
identified nearly $7.5 billion of opportunities across 
all of our businesses, providing additional growth well 
into the future.
Throughout 2021 and into 2022, there have been several 
significant legislative and regulatory changes that continue 
to create positive benefits for the environment while 
providing significant business opportunities for our core 
service offerings. These include the U.S. rejoining the 
Paris Climate Agreement and making commitments to 
100% clean electricity by 2035. In November 2021, the 
Infrastructure Investment and Jobs Act became law, which 
provides increased opportunity for fly ash to be recycled 
and beneficially used in the production of green concrete 
to meet the growing infrastructure demand, providing an 
environmentally conscious replacement for Portland cement 
in the production of ready mix concrete and concrete 
products. Most recently, in January 2022, the EPA acted 
to expand and strengthen the regulation for coal ash and 
groundwater management of regulatorily mandated surface 
impoundments and landfills, marking the first time the EPA 
has enforced the 2015 Coal Combustion Residuals Regulation 
from coal-fired power plants for the management of ash 
impoundments and landfills, which we view as positive for 
our business as it should increase the amount of remediation 
work required by power plant owners.
Charah Solutions is well positioned to capitalize on these 
growing needs across the industry by virtue of our single-
source solution and an expanding market for our ERT 
services. We will continue to build upon our competitive 
strengths and service advantages to provide superior 
solutions to customers, expand our footprint, and increase 
market share by clearly focusing on our strategic priorities.
2022 KEY GROWTH AND PROFIT DRIVERS

12
Remediation Contract Acceleration and 
Service Advantages
Our Remediation and Compliance Services continue to be 
the highest potential growth engine of our Company. The 
EPA has estimated that there are more than 1,000 active 
and inactive onsite landfill and surface impoundments, 
including 500 that have groundwater contact issues, 
substantially all of which will require remediation or closure. 
These sites will require significant capital expenditures 
from the utilities and specialized environmental expertise to 
monitor them on an ongoing basis, remediate and relocate 
the waste, or completely close the impoundment. We believe 
that the January 2022 EPA announcement that expands and 
strengthens regulations affecting coal ash and groundwater 
management of mandated surface impoundments and 
landfills is very positive for our addressable market over the 
next several years, as it significantly expands the amount 
of remediation work utilities will be required to perform. 
We continue to see significant growth opportunities in our 
Remediation and Compliance Services business as we 
believe we are a partner of choice for our customers due 
to our reputation as a leader in quality and safety, domain 
experience, and compliance record, all of which are key 
criteria for our customers.
We expect our competitive advantage in strategically 
bundling our services and core strengths of ash remediation 
and byproduct services with our proprietary EnviroSource 
technology to be unmatched in the industry. We are well-
positioned to provide cost-effective solutions to meet the 
ongoing demands of our customers while preserving our 
natural resources in an environmentally conscious manner.
Byproduct Services Growth
According to the American Coal Ash Association’s (ACAA’s) 
2020 Production and Use Survey, the rate of coal ash 
recycling overall in the U.S. increased in 2020 by 7%, 
reversing two years of declines. With the increasing focus 
on CO2 emissions, more states, regulatory authorities, and 
concrete producers are realizing the environmental benefit 
of substituting fly ash for Portland cement which also 
provides cost savings for ready mix producers and lower 
rates for utility customers as the utility generates revenues 
from the sales. This increased rate of ash recycling is 
also expected to increase as a result of the Infrastructure 
Investment and Jobs Act, as this provides increased 
opportunity for fly ash to be recycled and beneficially used 
in the production of green concrete to meet the growing 
infrastructure demand, providing an environmentally 
conscious replacement for Portland cement in the 
production of ready mix concrete and concrete products. 
With this expectation for more significant infrastructure 
spend and already increased market demand, we expect 
higher demand for our ash byproducts and raw materials in 
2022 and beyond.
We also continue to strategically expand our byproducts 
network reach to customers around the country by adding 
additional terminals to ensure the supply is available in areas 
of highest demand. Our MultiSource® materials network 
includes nearly 40 nationwide locations with international 
sourcing and distribution as well as a national network of 
barge, rail and truck services for quick and reliable material  
across the country, giving us a competitive advantage over 
other suppliers in meeting the expanding needs of this 
market for quality fly ash and other SCMs.

13
EnviroSource Ash Beneficiation Technology
There is also the reality of more coal-fired power 
generation plants going offline at a steady pace, which 
can lead to less fly ash and other byproducts being 
produced for marketing to ready mix producers. Plus, 
state and local legislation continue to drive regulations 
for the beneficial use of ponded ash in large ash 
pond remediation projects where this ash may not 
meet specification grade for use in the production of 
green concrete. This is where the embedded nature 
of our operations and our investment in technology 
pays off to provide higher margin offerings to our 
customers while also improving the environment at 
the same time. Our proprietary EnviroSource fly ash 
beneficiation technology converts previously unusable 
coal ash into consistent, high-quality fly ash that 
meets industry specifications, increasing marketable 
fly ash supply to concrete producers nationwide.
Our EnviroSource beneficiation technology enables greater 
amounts of coal ash to be recycled and beneficially used 
in making cement, which preserves natural resources 
while reducing the need for landfills. Substituting recycled 
ash to make green concrete makes a stronger, lower-cost 
product for use in bridges, highways, and buildings. We 
continue to make significant progress and receive strong 
interest in our EnviroSource ash beneficiation technology 
from utility customers, both domestically and internationally, 
and are optimistic that we will reach our first commercial 
agreement for the use of our EnviroSource fly ash 
beneficiation technology in the first half of 2022.
We expect this innovative technology will allow us to 
optimize our traditional fly ash marketing and distribution, 
and enter new markets for our products while providing 
cleaner, environmentally-friendly solutions to our customers. 
2022 KEY GROWTH AND PROFIT DRIVERS

14
Environmental Risk Transfer (ERT) Services Growth
According to the EIA, between 2010 and the first 
quarter of 2019, U.S. power companies announced the 
retirement of more than 546 coal-fired power plants, 
totaling approximately 102 GW of generating capacity. 
There are plans to retire another 17 GW of coal-fired 
capacity by 2025. These retired coal-fired power 
plants represent a massive opportunity for our growing 
ERT services where the utilities have the need to retire 
and decommission their older generating assets while 
minimizing their costs and improving the environment 
in the process.
Through our ERT services, we acquire the coal-fired 
power plant and land from the utility partner and take 
on the environmental liabilities associated with these 
properties. Charah Solutions performs all services to 
remediate the land, which involves shutting down the 
plant, decommissioning and demolishing the existing 
coal-fired power plant, remediating onsite ash ponds 
and landfills, and restoring the land for community 
or business use. This ERT approach not only benefits 
the utility but also the environment while providing 
economic benefits as it creates local professional 
and trade jobs, contributes to local business activity, 
supports the tax base, and lowers the costs for the 
utility and its ratepayers. Few companies can combine 
the environmental expertise and the financial scale to 
provide utilities with our level of ERT services. 
We made major progress in 2021 to build on the success 
of our growing ERT business with the acquisition of GenOn 
Energy’s Avon Lake and Cheswick Generating Stations and, 
more importantly, we completed the sale of 100% of the 
real property acreage at our Gibbons Creek ERT project in 
less than a year since acquisition. The increasing needs for 
ERT projects play a leading role in our nearly $7.5 billion 
of opportunities across all of our business, and we expect 
it to provide substantial growth well into the future. We 
believe we have a distinct competitive advantage through 
our integrated ERT services in the marketplace, and we 
are dedicating additional resources to expand our ERT 
opportunities.
Proven Safety Leadership
Keeping our employees safe will always remain our top 
priority, as it is a core value that we live every day. As noted 
in our recent 2021 ESG Report, our impressive safety 
record is a highlight of our Company’s performance. We 
also know that safety is something that we can never take 
for granted. Safety is never done. It demands daily focus 
and extensive training every day on the job so that our 
employees will be able to leave every one of our job sites 
the way they arrived. We always strive to meet the highest 
safety standards and implement ongoing safety programs 
and protocols which continue to exceed our Company goals 
and make us an industry safety leader.

15

Our MultiSource network has grown to become an 
important strategic advantage of Charah Solutions. For 
utilities, it helps keep their fly ash moving more efficiently 
for faster marketing, and concrete producers count on it 
for a consistently reliable supply of high-quality SCMs – 
all supported by our Charah Solutions team.
Coal ash management is mission-critical to power plants’ 
daily operations as they generally only have onsite storage 
capacity for three to four days of CCR accumulation. 
Through our utility support services, we focus on 
recurring and daily onsite management operations 
for coal-fired power generation facilities to fulfill our 
customers’ environmental service needs in handling 
their waste byproducts. These services include silo 
management, onsite ash transportation and capture, and 
disposal of ash byproduct from coal-power operations. 
Our operations cover the management of a wide variety 
of combustion byproducts, including bottom ash, flue gas 
desulfurization (FGD) gypsum disposal, Pozatec/fixated 
scrubber sludge disposal, and fluidized bed combustion 
fly ash disposal. We coordinate all aspects of the ash 
management operation, from processing and screening 
for sales to facilitating economical disposal.
Raw Materials Sales
With dedicated resources located in the U.S., London, and 
Singapore, our Raw Materials Sales provide customers 
around the globe with the raw materials that are essential 
to them maintaining a competitive edge in their global 
business. They recognize Charah Solutions as the ideal 
global partner with the sourcing, logistics, and dedicated 
resources to help them source, move, manage, and 
better utilize quality industrial raw materials and cement 
manufacturing raw materials and facilitate raw materials 
transactions around the globe.
Environmental Risk Transfer (ERT) Services
Through our ERT services, we provide innovative solutions to 
large-scale, complex environmental issues facing utilities. With 
the growing shutdown of coal-fired power plants around the 
country, many utilities have an increased need to retire and 
decommission older generating assets while minimizing their 
costs and improving the environment in the process. As part 
of our ERT services, Charah Solutions acquires the coal-fired 
power plant and land from the utility partner and takes on 
the environmental liabilities associated with these properties. 
Charah Solutions performs all services to remediate the land, 
which involves shutting down the plant, decommissioning and 
demolishing the existing coal-fired power plant, remediating 
onsite ash ponds and landfills to meet all local, state and 
federal regulations, and redeveloping the land for community 
use, business use or natural habitat restoration.
This ERT approach not only benefits the environment but also 
provides economic benefits as it creates local professional and 
trade jobs, contributes to local business activity, supports the 
tax base, and lowers the costs for the utility and its ratepayers. 
Few companies can combine the environmental expertise 
and the financial scale to provide utilities with ERT services, 
but this turnkey service is designed to pay big dividends for 
the environment as well as for the power companies and 
the ratepayers who no longer have to support these older, 
inefficient plants financially.

service provider of mission-critical environmental services and byproduct recycling to the power generation industry. We offer a suite of 
remediation and compliance services, byproduct services, raw material sales and Environmental Risk Transfer ("ERT") services. We also design 
and implement solutions for complex environmental projects (such as coal ash pond closures) and facilitate coal ash recycling through byproduct 
marketing and other beneficial use services. We believe we are a partner of choice for the power generation industry due to our quality, safety, 
domain experience and compliance record, all of which are key criteria for our customers. In 2021, we performed work at more than 40 coal-fired 
generation sites nationwide.
Charah Solutions, Inc. was incorporated in Delaware in 2018 in connection with our initial public offering in June 2018 and, together with 
its predecessors, has been in business since 1987. Since our founding, we have continuously worked to anticipate our customers’ evolving 
environmental needs, increasing the number of services we provide through our embedded presence at their power generation facilities. Our 
multi-service platform allows customers to efficiently source multiple required offerings from a single, trusted partner compared to service 
providers with a more limited scope.
On November 19, 2020, the Company sold its Allied Power Holdings LLC (“Allied”) subsidiary engaged in maintenance, modification and 
repair services to the nuclear and fossil power generation industry to an affiliate of Bernhard Capital Partners Management, LP (“BCP”), the 
Company’s majority shareholder, in an all-cash deal for $40 million (the “Allied Transaction”) subject to customary adjustments for working 
capital and other adjustments as set forth in the Purchase Agreement. As described in further detail in Part II, Item 8. Financial Statements and 
Supplementary Data, the Company has presented Allied as discontinued operations in the accompanying consolidated financial statements and 
related notes.
We operate as a single operating segment, reflecting the suite of end-to-end services we offer our utility partners and how our chief 
operating decision maker reviews consolidated financial information to evaluate results of operations, assess performance and allocate 
resources for these services. We provide the following services through our one segment: remediation and compliance services, byproduct 
services, raw material sales and ERT services. Remediation and compliance services are associated with our customers’ need for multi-year 
environmental improvement and sustainability initiatives, whether driven by regulatory requirements, power generation customer initiatives or 
consumer expectations and standards. Byproduct services consist of recurring and mission-critical coal ash management and operations for 
coal-fired power generation facilities while also supporting both our power generation customers’ desire to recycle their recurring and legacy 
volumes of coal combustion residuals (“CCRs”), commonly known as coal ash, and our ultimate end customers’ need for high-quality, 
cost-effective supplemental cementitious materials (“SCMs”) that provide a sustainable, environmentally-friendly substitute for Portland cement 
in concrete. Our raw materials sales provide customers with the raw materials that are essential to their business while also providing the 
sourcing, logistics, and management needed to facilitate these raw materials transactions around the globe. ERT services represent an 
innovative solution designed to meet utility customers' evolving and increasingly complex plant closure and environmental remediation needs. 
These customers need to retire and decommission older or underutilized assets while maximizing the asset's value and improving the 
environment. Our ERT services manage the sites' environmental remediation requirements, benefiting the communities and lowering the utility 
customers' costs.
As a result of our comprehensive offerings, the embedded nature of our on-site presence, our domain experience, and our track record 
of successful execution, we have built long-term relationships with leading U.S. regulated utilities and independent power producers, including 
Dominion Energy, Inc., Duke Energy Corporation, Dynegy Inc., PPL Corporation, The Southern Company, and Consumers Energy, among 
others. These relationships have spanned more than 20 years in some cases. Our operational footprint's national scale is also a key competitive 
differentiator, as many competitors are localized, focusing on a single geographic area (sometimes isolated to a single plant). We operate in 
more than 20 states, resulting in an overall footprint and density in key markets that we believe are difficult to replicate. We believe our national 
reach enables us to successfully pursue new business within our existing customer base and attract new customers while providing consistent 
quality, safety, and compliance standards.
Our services platform is led by a senior executive team with deep industry experience and is supported by a highly skilled labor force. 
The nature of our work requires employees to have specialized skills, training, and certifications for them to be allowed on-site at our customers’ 
facilities. Collectively, our focus on human capital management enables us to maintain and develop a labor force of highly qualified, well-trained 
personnel capable of handling our customers’ needs.

Market Opportunity 
The U.S. power generation industry is composed of critical infrastructure providing essential electric power to communities nationwide. 
According to the U.S. Energy Information Administration (the “EIA”), as of 2019, there were approximately 500 large-scale facilities in the United 
States with generation capabilities of at least 250 megawatts, including more than 150 coal-fired power plants. With near-constant demand from 
consumers and industry, these facilities' continuous operation is critical given potentially high economic and reputational costs of downtime. 
These complex facilities have specialized and recurring environmental and compliance service needs to maintain continuous operations 
throughout their lifecycles. These service needs are particularly significant for coal-fired plants due to the increasing demands of environmental 
regulation, the aging nature of the installed base, and the feedstock characteristics required to power such facilities. Due to the breadth and 
scope of these service needs, power plant operators typically do not possess the necessary capabilities internally and instead outsource these 
mission-critical and often regulatory-driven requirements to a fragmented set of service providers. Many significant dynamics support the 
continuing need for these specialized services. 
Coal-Fired Power Plants Have Significant and Recurring Environmental Management Needs Associated with Their Waste Byproducts 
Coal-fired power plants consistently generate various waste byproducts throughout the power generation process. The primary type of 
these waste byproducts is CCRs. CCRs come in multiple forms, including fly ash, bottom ash, and boiler slag, and are collected throughout the 
coal burning process. Although not considered a hazardous waste under the Resource Conservation and Recovery Act, as amended (the 
“RCRA”), utilities have significant regulatory and reputational risks associated with the handling and disposal of coal ash. According to the 
American Coal Ash Association, approximately 70 million tons of coal ash were produced in 2020, the latest year for which data is available. 
Coal ash management is mission-critical to coal-fired power plants' daily operations as they generally have on-site storage capacity for only 
three to four days of CCR waste accumulation. This limited coal ash storage capacity requires continuous daily monitoring, handling, 
transportation, and disposal to enable ongoing power plant operation. The U.S. Environmental Protection Agency (the “EPA”) has estimated that 
coal-fired utilities spend approximately $2.9 billion per year on coal ash management. Power plant operators typically engage specialized service 
providers to conduct this critical recurring activity on-site alongside their plant personnel. 
Large Installed Base of Legacy Coal Ash Disposal Ponds That Require Remediation 
Collected coal ash is disposed of or beneficially used (recycled) in a range of applications. According to the American Coal Ash 
Association, utilities disposed of approximately 41% of coal ash produced in the United States during 2020. According to EPA data published, of 
the CCRs generated that were not beneficially used, approximately 80% were disposed in on-site disposals units, with the balance transported 
and disposed of off-site at third-party landfills. For many years, coal-fired power plants relied on ash ponds as the primary disposal locations for 
CCRs. The vast majority of these older inactive and older existing ash ponds were constructed without the design standards now mandated by 
regulation to prevent harm to the environment, and those ponds will require remediation or closure in the future. The EPA estimated that there 
are more than 1,000 active and inactive on-site landfill and surface impoundments, substantially all of which will require remediation or closure. 
These sites will require significant capital expenditures from their owners and specialized environmental expertise to monitor them on an ongoing 
basis, remediate and relocate the waste, or completely close. 
Power Plant Operators Are Increasingly Focused on Environmental Stewardship and Regulatory Compliance 
Power plant operators face increasing pressure from regulators, advocacy groups, and their communities to manage the environmental 
risks associated with their operations. Therefore, the industry is increasingly focused on environmental stewardship. Due to the potentially 
considerable consequences of environmental liabilities, spending on environmental liability management has increased over time and is 
expected to increase in the future. 
Additionally, power plants are highly regulated by environmental authorities at the federal, state, and local government levels, which 
have recently added compliance requirements. A recent example is the Disposal of Coal Combustion Residuals From Electric Utilities; Final 
Rule (the “CCR Rule”). The EPA enacted the CCR Rule in April 2015 in response to two significant coal ash spills in Kingston, Tennessee and 
Eden, North Carolina, that caused widespread environmental damage. The CCR Rule regulates the disposal of coal ash as a solid waste. It 
established new requirements for the closure and remediation of existing coal ash ponds and restrictions on the location of new ash ponds. The 
CCR Rule will result in significant incremental environmental management costs for many industry participants. Also, the power generation 
industry is proactively implementing environmental best practices across their assets, even when not yet required by law. 
Recycling Waste Byproducts Is a Critical Component of the Coal Ash Value Chain 
Coal ash can be recycled to produce positive environmental, economic, and performance benefits, such as lower greenhouse gas 
(“GHG”) emissions, reduced use of other natural resources and improved strength and durability of materials. 
 
2

 
 
According to the American Coal Ash Association, approximately 41 million tons, or 59%, of coal ash produced in the United States was 
beneficially used in 2020. The leading beneficial use of coal ash is as a direct and more economical substitute for cement during the production 
of concrete (approximately 11 million tons of CCRs production and use in 2020). There are many good reasons to view coal combustion 
residuals as a resource rather than a waste. Recycling them conserves natural resources and saves energy. 
In many cases, products made with CCRs perform better than products made without them. For instance, coal fly ash makes concrete 
stronger and more durable. It also reduces the need to manufacture Portland cement, resulting in approximately 12 million tons of greenhouse 
gas emissions reductions each year. An economic analysis by the American Road and Transportation Builders Association estimates that coal 
fly ash used in roads and bridges saves approximately $5.2 billion per year in U.S. construction costs. Additionally, technologies currently 
available, including our EnviroSourceTM multi-process ash beneficiation technology, improve the characteristics of certain types of coal ash, 
making them more viable for recycling purposes and ultimately increasing the addressable market of recyclable coal ash. 
Coal Power Generation Remains an Important Energy Source 
According to the EIA, while renewable energy and natural gas sources are expected to provide an increasing share of U.S. domestic 
energy production, coal-fired power generation is expected to remain a key baseload energy source for decades, providing at least 0.9 trillion 
kilowatt-hours of energy production annually through 2050. In 2020, coal power generation accounted for approximately 20% of domestic U.S. 
energy generation. Coal power generation is projected to increase to 23% between 2021 and 2022, following a decline during 2020 from lower 
demand due to the coronavirus (“COVID-19”) pandemic and increasing demand for competing fuels used for power generation. Despite 
short-term improvements, coal-fired capacity will continue to shrink. Based on current plans, the EIA projects the removal of about 2.7 gigawatts 
(“GW”) of coal power generation capacity in 2021, following the loss of about 9.4 GW in 2020. From 2021 to 2025, the EIA forecast that about 
25.2 GW of coal-fired capacity will be removed. Although other energy generation sources, such as natural gas and renewables, are expected to 
make moderate gains on a percentage contribution basis, we believe the aggregate demand for coal power generation will remain consistent as 
the installed base of coal plants is deeply entrenched throughout the U.S. national power grid. 
The Power Generation Industry Increasingly Requires Larger Scale Environmental Service Providers 
The mounting burden of environmental compliance, the constant need to maintain aging facilities, and the focus on continuous and safe 
plant operations have the power generation industry, particularly the coal-fired energy producers, increasingly seeking to partner with outsourced 
service providers having a larger and broader scale that can provide a range of services on their behalf. Most prospective service providers 
either have narrow service offerings or a highly localized geographic focus (sometimes limited to a single plant). Few service providers can offer 
broad service capabilities with a track record of quality service, exceptional safety, exacting environmental standards, and a reliable labor force 
like Charah Solutions. 
According to the EIA, after substantial retirements of U.S. coal-fired electric generating capacity from 2015 to 2020 that averaged 11.0 
GW a year, coal capacity retirement slowed to less than 5.0 GW in 2021. However, we expect the retirement of coal-fired generators to increase 
again this year; 12.6 GW of coal capacity is scheduled to retire in 2022, or 6% of the coal-fired generating capacity. 
U.S. coal plants are retiring as the coal fleet ages and as coal-fired generators face increasing competition from natural gas and 
renewables. According to the EIA, power plant owners and operators have reported that they plan to retire 28%, or approximately 59.0 GW, of 
the coal-fired capacity currently operating in the United States by 2035. Since 2002, around 100 GW of coal capacity has retired in the United 
States, and the capacity-weighted average age at retirement was 50 years. As of September 2021, 212 GW of utility-scale coal-fired 
electric-generating capacity was operating in the United States, most of which was built in the 1970s and 1980s. 
After a coal-fired plant is retired, the site will undergo a multi-year decommissioning, remediation and closure process. Remediation of 
CCRs is the main focus of coal plant decommissioning. Depending on the facility, CCRs are disposed of in on-site landfills or coal ash ponds or 
are beneficially reused in other products. 
Many utilities are experiencing an increased need to retire and decommission older or less economically viable generating assets while 
minimizing costs and maximizing the asset's value and improving the environment. Our ERT services allow these partners to remove the 
environmental risk and insurance obligations and place control and oversight with a company specializing in these complex remediation and 
reclamation projects. We believe our broad set of service capabilities, track record of quality service and safety, exacting environmental 
standards, and a dependable and experienced labor force is a significant competitive advantage. Our work, mission and culture are directly 
aligned with meeting environmental, sustainability, and governance (“ESG”) standards and providing innovative services to solve our utility 
customers’ most 
3

 
 
complex environmental challenges. We believe that we are an industry leader in quality, safety, and compliance, and we are committed to

strengths that support our leading position include: 
Industry-Leading Quality, Safety, and Compliance 
We believe we are a partner of choice for our customers due to our reputation as a leader in quality, safety, and compliance. Utilities and 
independent power producers are generally risk-averse and focus on environmental and safety considerations as crucial factors for awarding 
on-site service provider contracts. We believe our reputation for and dedication to quality, industry-leading safety record, and adherence to 
environmental compliance standards provide a distinct competitive advantage and differentiate us from many of our competitors. We believe we 
have developed trusted relationships and credibility with regulatory agencies supported by our team of in-house compliance experts. We pride 
ourselves on being a reliable partner to our customers, consistently delivering high-quality, efficient, and on-time service. 
These attributes are vital contributors to our leading market share positions. Our leading capabilities position us well for potential new 
business as customers recognize the value of engaging a proven service partner. 
Broad Platform of Mission-Critical Environmental Services 
Our broad platform of essential environmental services has enabled us to become a leading service provider to our power generation 
customers. In our end markets, we are a leading national service provider offering a suite of remediation and compliance services, byproduct 
services, raw material sales and ERT services. Our multi-service platform allows customers to gain efficiencies from sourcing multiple required 
offerings from a single, trusted partner compared to service providers with a more limited scope. 
The national scale of our operational footprint is also a key differentiator, as many of our competitors are localized, focusing on a single 
geographic area (sometimes isolated to a single plant). We operate in more than 20 states across the country, resulting in an overall footprint 
and density in key markets that we believe are difficult to replicate. Our national reach enables us to successfully pursue new business within our 
existing customer base and attract new customers while providing consistent quality, safety, and compliance standards. 
Long-Term Partnerships with Leading Power Generators 
Our customers are some of the largest power generation companies in the United States, including Dominion Energy, Inc., Duke Energy 
Corporation, Dynegy Inc., PPL Corporation, The Southern Company and Consumers Energy. Given our services' essential nature, our on-site 
personnel becomes integrated into each facility's daily procedures, seamlessly working with utility employees to provide uninterrupted 
continuous operations. Our co-location and integration into our customers’ daily operations result in direct relationships with key decision-makers 
at every level of our customers’ organizations. We believe this embedded partnership deepens customer connectivity and drives longer 
customer tenure. In some cases, these relationships have spanned more than 20 years. For example, LG&E and KU Energy LLC, which PPL 
Corporation currently owns, have been customers for more than 20 years. We have also demonstrated the ability to grow our service offerings 
with a single customer. We first provided Duke Energy Corporation with byproduct services in 2001 at two plants, and we now provide all of our 
coal-related services across nine of their plants. We believe these long-term relationships are critical for renewing existing contracts, winning 
incremental business from existing customers at new sites, and adding new customers. 
Innovative Solutions to Our Customers’ Environmental Challenges 
Our customers regularly face complex, large-scale environmental challenges that require bespoke, technical solutions. We believe we 
have a proactive and differentiated approach to solving these challenges. Our internal technical and engineering experts have developed 
in-depth domain knowledge and capabilities in environmental remediation and the beneficial use of coal ash due to our long-term and significant 
experience in the sector. We believe this credibility, combined with an entrepreneurial mindset, enables us to source market opportunities not 
readily available to our competitors. 
For example, we demonstrated this innovative approach for a major reclamation project at the Asheville Regional Airport in North 
Carolina. In the course of remediating an on-site ash pond at a nearby coal power plant, we had the vision to beneficially use that ash as 
structural fill to support a newly constructed taxiway at the airport. Our engineers designed a state-of-the-art, highly engineered structural fill 
system to capture the ash in an environmentally sound way. Asheville Regional Airport saved approximately $12 million by using coal ash 
instead of traditional materials, and approximately 4 million cubic yards of coal ash from an ash pond were beneficially used. We believe this 
innovative approach, coupled with new technologies and processes, generates additional value for our customers and stockholders.

Furthermore, our ERT turnkey project for Consumers Energy in Michigan is another example of our creative solutions to a complex 
problem. Remediating the existing ash ponds at the B.C. Cobb facility was part of the site's post-closure regulation requirements and 
sustainability objectives. Additionally, the utility and the community wished to further advance the wetlands along the eastern shore of Lake 
Michigan. We provided Consumers with a cost-effective proposal to meet these goals, provide remediation of the ponds and repurpose the site 
to natural wetlands. 
We further demonstrated our innovative approach to customer’s environmental challenges through our turnkey ERT services in 
acquiring the Texas Municipal Power Agency's Gibbons Creek Steam Electric Station and Reservoir in Grimes County, Texas. As part of the 
asset purchase agreement, the Company, through one of its subsidiaries, acquired the 6,166-acre area that included the closed power station 
and adjacent property, the 3,500-acre reservoir, dam and spillway and assumed responsibility for the shutdown and decommissioning of the coal 
power plant as well as the performance of all environmental remediation work for the site landfills and ash ponds. As a sustainability leader in 
utility services, the Company is redeveloping the property in an environmentally conscious manner designed to expand economic activity and 
benefit the surrounding communities through job creation, promotion of industry, support of the tax base, as well as restoring the property to a 
state that will enable it to be put to its best potential use. 
Entrepreneurial Management Team Supported by Highly Skilled Labor Force 
We are led by an experienced management team with an entrepreneurial mindset and a keen focus on safety and customer service. Our 
senior executive team consists of industry veterans with deep industry experience, helping us provide high-quality operational execution and 
solidify long-term customer relationships. In addition to a commitment to developing internal talent, we have made key strategic external hires to 
deepen our expertise further. Our entrepreneurial mindset drives us to continually search for new ways to maximize customer relevance and 
develop innovative solutions. 
Our customers have unique certification and training requirements for the service providers they allow on-site. Our ability to hire, 
develop, and retain a highly-skilled labor force with specialized skills, training, and certifications is a critical differentiator in the sector. We also 
have a dedicated team of in-house professionals that focus exclusively on training, certification, and mentorship. As part of our commitment to 
safety and compliance, each of our on-site employees must complete a unique, rigorous training program. We train our managers to lead from 
the front line and share, involve, and support their teams. Our ability to staff large-scale projects rapidly is also critical. Collectively, our human 
capital management allows us to maintain and develop a labor force of highly qualified, well-trained personnel capable of handling our 
customers’ needs. 
 
Our Growth Strategy 
Expand Market Share by Capitalizing on the Significant Needs of Power Generation Customers 
We have a substantial growth opportunity in the near term as U.S. coal-fired power generation facilities continue to remediate and close 
coal ash ponds and landfills. These projects are triggered as coal power plant operators preemptively manage environmental liabilities, comply 
with regulatory requirements (at the local, state, and federal levels), and work to meet consumer standards for environmental sustainability. We 
believe there are $75 billion in coal ash remediation opportunities in the United States, driving a need for creative remediation solutions, 
including the beneficiation of ash. We estimate there are more than 1,000 active and inactive landfills and surface impoundments, substantially 
all of which will require remediation or closure. We expect that customer spending for our core services, including ash pond and landfill 
remediation, will increase significantly over the next three to five years in response to these remediation requirements. We believe spending on 
coal ash management will increase due to our customers’ increased focus on environmental stewardship. 
Continue to Grow On-Site Services Revenue by Expanding Our Offerings 
We believe our broad platform of services is a competitive differentiator and, therefore, continuing to enhance the breadth of services 
offered to our existing customers is a key growth opportunity. We are a trusted partner and our team is embedded with the customer on-site to 
handle its most critical operational needs. As a result, we are well-positioned to identify relevant, attractive service offerings to add to our 
portfolio. We believe significant opportunities exist in remediation and compliance services and byproduct services across our platform. We have 
earned our reputation as the premier one-stop solution to the power generation industry for ash pond remediation and compliance, 
environmentally friendly ash recycling and daily ash operations. We believe our customers will continue to find value in a full-service platform 
and source incremental services from us as an existing, on-site, trusted partner. 
Leverage New and Existing Customer Relationships to Maximize Fleet-Wide Opportunities 
The trend among our customers is to consolidate service providers. Given the breadth of our service offerings and our access to our 
customers’ senior decision-makers, we believe we are well-positioned to deepen our relationship with current customers by providing our 
services to other coal-fired power plants within their fleets. We see an opportunity to increase this percentage meaningfully. We will also seek to 
generate business with new utility customers and compete fleet-wide across their power plant footprints. We see similar opportunities in 
international geographies. 
5

 
 
Invest in Innovative Technologies, Processes, and Solutions 
We believe investments in new technology and processes present opportunities to provide higher-margin offerings while improving the 
environment. Our operations' embedded nature gives us a superior understanding of unique customer problems allowing us to deploy innovative 
solutions. We believe there are opportunities for technological innovation in environmental compliance and stewardship. For example, our 
EnviroSourceTM ash beneficiation technology provides an innovative new proprietary thermal process for fly ash beneficiation. This technology 
converts previously unusable coal ash into consistent, high-quality fly ash that meets industry specifications, increasing marketable fly ash 
supply to concrete producers nationwide. We expect these innovative technologies will allow us to optimize our traditional fly ash sales and 
distribution, enter new markets for our products, and provide cleaner, environmentally friendly solutions to our customers. We intend to continue 
to invest in new technologies and other processes that expand our portfolio of solutions and further establish us as an innovator in our industry. 
 
Our Services 
We deliver services and solutions to the power generation industry through one reportable segment. We have over 30 years of 
experience constructing, operating, and managing structural fill projects for coal-fired utilities and assisting coal-fired utilities in beneficially using 
waste byproducts. We offer a suite of end-to-end services providing remediation and compliance services, byproduct services, raw material 
sales and ERT services. Our remediation and compliance services primarily include environmental management of landfills for coal-fired power 
generation facilities and new and existing active pond management, including closure by removal, cap-in-place, and design and construction of 
new ponds. Additional service offerings include all aspects of landfill development, construction, and management. Our remediation and 
compliance services teams can also provide site evaluation and characterization; preliminary design and cost estimates with life-cycle analysis; 
hydrogeological assessments; groundwater and containment modeling; permit application and processing for expansions and greenfield sites; 
design engineering; construction of landfills and cap and cover systems; conversion of impoundments to landfill sites; quality assurance and 
quality control and documentation; engineered fills (off-site) and other related services. 
Our byproduct services offerings include recycling recurring and contracted volumes of coal-fired power generation waste byproducts, 
such as bottom ash, fly ash, and gypsum byproducts, as sustainable and environmentally-friendly construction materials. These byproducts can 
be used for various industrial purposes, including producing concrete products as a replacement for Portland cement. Our dedicated sales and 
marketing team has a national presence, and it works with many of the nation’s largest power generators to identify opportunities to improve 
each customer’s long-term position in the market while providing concrete producers with the consistent fly ash sourcing they need. With various 
coal sources being utilized across the power generation industry, we evaluate, process, and market the different bottom ash products to achieve 
the highest value for a given market area. Our byproduct services offerings also include coal ash management, which is mission-critical to the 
daily operations of power plants as they generally only have on-site storage capacity for three to four days of CCR waste accumulation. These 
services offerings focus on recurring and daily onsite management operations for coal-fired power generation facilities to fulfill our customers' 
environmental service needs in handling their waste byproducts. These services include silo management, on-site ash transportation and 
capture and disposal of ash byproducts from coal power operations. Our operations cover the management of a wide variety of combustion 
byproducts, including bottom ash, flue gas desulfurization ("FGD") gypsum disposal, Pozatec/fixated scrubber sludge disposal, and fluidized bed 
combustion fly ash disposal. We coordinate all aspects of the ash management operation, from processing and screening for sales to facilitating 
economical disposal. 
Our raw materials sales provide customers with the raw materials that are essential to their business while also providing the sourcing, 
logistics, and management needed to facilitate these raw materials transactions around the globe. 
Our ERT services represent an innovative solution designed to meet the utility customers' evolving and increasingly complex plant 
closure and environmental remediation needs. These customers need to retire and decommission older or underutilized assets while maximizing 
the asset's value and improving the environment. Our ERT services manage the sites' environmental remediation requirements benefiting the 
communities and lowering utility customers' costs. We provide a custom, environmentally-friendly approach to these large-scale projects that 
removes the liability from the utility through the acquisition of the property. We then provide environmental remediation of the ash ponds and 
landfills to meet all local, state and federal regulations. We will then redevelop the property upon project completion for public use, which 
typically includes natural habitat restoration for marine and other wildlife. 
 
Safety Record 
Utilities and independent power producers are focused on environmental and safety considerations as crucial factors for awarding 
on-site service provider contracts. We believe our strong safety record provides a distinct competitive advantage. We believe we have developed 
trusted relationships and credibility with regulatory agencies and utilities over the past 30 years 
6

 
 
due to our long-standing safety record supported by an experienced team of in-house safety and regulatory compliance professionals. 
Safety is integral to our culture and our results, and it is one of our core values. We believe we operate under the strictest safety 
standards, and we are committed to maintaining a safe working environment. Our dedicated in-house team of safety professionals develops and 
trains our employees and subcontractors to perform their jobs safely and proactively contribute to a safe workplace. This expert team includes 
highly trained professionals who are accredited Occupational Safety and Health Administration trainers, along with full-time transportation 
specialists in both over-the-road and rail operations. 
We recognize the unique safety issues related to working with our utility industry partners. Our Engineering, Environmental, and Quality 
Group has the expertise and experience to ensure our operations are compliant with local, state, and federal regulations and exceed our 
industry's customary safety standards. 
 
Sales and Marketing 
Our MultiSource® materials network is a unique distribution system of nearly 40 locations serving the United States, Mexico, and 
Canada with sourcing, transportation modes, and distribution options that ensure a steady and reliable supply of supplementary cementitious 
materials (“SCMs”). The MultiSource® materials network provides SCMs to markets where they are needed and sufficient storage to level out 
seasonal supply and demand fluctuations. Logistics support must include an established network of transportation options, including truck, rail, 
and barge, as well as sufficient storage and supply capabilities to meet the on-time delivery requirements of customers. By combining the 
strengths of our EnviroSourceTM ash beneficiation technology, the proven MultiSource® network, and strategic investment in logistics 
infrastructure, we can meet demand in regions not previously attainable while maintaining a competitive price, consistent quality and supply for 
concrete producers. 
Our dedicated sales and marketing team has built successful and long-term relationships with the nation’s largest power generators. We 
think we can leverage the deep connections and strong operational track record we have built to broaden our on-site presence and deepen client 
partnerships. We also seek to grow our business with new power generation customers and compete enterprise-wide across their power plant 
footprints. Through close connections with utility management and personal relationships developed daily by our network of embedded field 
teams of regional managers and site managers, we believe we understand our customers’ needs and that we can quickly respond to their 
project requirements and provide creative solutions. Our team includes professional engineers, experienced site managers, and seasoned 
estimators who strive to be detailed, accurate, and upfront, enabling us to minimize contract modifications after the work begins. We employ 
what we refer to as a “zippered” organizational approach to customer service and marketing, leveraging relationships up and down the 
organization. By structuring our organization around our customers’ needs through this unique network of regional field operations managers, we 
ensure that projects are completed on time and within budget. Additionally, we can quickly recognize opportunities to cross-sell and market our

Customers 
We have developed our long-term, committed relationships to become a preferred provider to many of the largest power generation 
companies in the United States. In 2021, we performed work at more than 40 plants for more than 20 “blue-chip” entities, including Ameren 
Corporation, Big Rivers Electric Corporation, Consumers Energy, Dominion Energy, Inc., Duke Energy Corporation, Hoosier Energy Rural 
Electric Cooperative, Inc., NRG Energy, Inc., PPL Corporation, The Southern Company and Vistra Corp. The majority of our power generation 
clients have investment-grade credit ratings. During the year ended December 31, 2021, three customers accounted for 36% of total 
consolidated revenue. As of December 31, 2021, these three customers accounted for 18% of total consolidated trade accounts receivable, net. 
If a major customer decided to stop purchasing our services, revenue could decline, and our operating results and financial condition could be 
adversely affected. 
Award Status 
In 2021, we won approximately $840 million in contracted new awards, the largest in the Company's history, as compared to $715 
million and $430 million in 2020 and 2019, respectively. Though the timing of future awards is difficult to determine, we believe we are 
well-positioned to capture a significant portion of a large and growing addressable market. 
Joint Ventures and Contractual Arrangements 
A portion of our byproduct services was provided through the following two joint ventures: 
Ash Venture Joint Venture 
In December 2013, we formed Ash Venture LLC, a North Carolina limited liability company (“Ash Venture”), which provides ash 
management and marketing services to the utility industry. Ash Venture is a joint venture between Charah, LLC, a Kentucky limited liability 
company and our wholly-owned subsidiary (“Charah”), and Titan America, LLC, an unrelated third 
 
7

 
 
party. Charah owns 67% of Ash Venture, and the third party owns 33%. During the year ended December 31, 2021, the agreement to provide 
ash management and marketing services with the third-party utility partner came to its conclusion, and the joint venture began settling its 
remaining current assets and liabilities through the normal course of business. 
Equity Method Investment 
In January 2016, we formed CV Ash, a joint venture with VHSC Holdings, LLC, an unrelated third party, which markets and sells fly ash 
to the ready-mix concrete market. We account for the joint venture under the equity method. Charah and the third party each own 50% of the 
joint venture. During the first quarter of 2021, the CV Ash joint venture relationship ended, and the joint venture began settling its remaining 
current assets and liabilities through the normal course of business. 
Competition 
The power and environmental services industries are highly fragmented across regional competitors. A limited subset of competitors 
provides a national presence, few of which offer the same spectrum of services we provide. Our competitors consist of a mix of large 
environmental and waste management businesses that do not specialize in ash management services and hundreds of regional and local 
companies with limited-service areas, typically servicing only one to three sites each. The highly fragmented and regional nature of our industry 
has produced a limited number of competitors with a national scope. 
We are a leading national service provider offering a suite of coal ash management and recycling services to the power generation 
industry. While some competitors are significantly engaged in one of the core areas in the power or environmental services value chain, many 
have limited or no engagement in most of our core areas. 
Seasonality 
Based on historical trends, we expect our operating results to vary seasonally due to demand within our industry as well as weather 
conditions. For additional information on the effects of seasonality on our operating results, see “Item 7. Management’s Discussion and Analysis 
of Financial Condition and Results of Operations—Key Factors Affecting Our Business and Financial Statements—Seasonality of Business.” 
Risk Management and Insurance 
The nature of our business exposes us to liabilities arising out of our operations, including possible damages to the environment. Such 
potential liabilities could involve, for example, claims for remediation costs, personal injury, property damage, and damage to the environment, 
including natural resources, claims of employees, customers, or third parties for personal injury or property damage occurring in the course of 
our operations, or claims alleging negligence or other wrongdoing in the planning or performance of work. We could also be subject to fines, civil 
and criminal penalties and other sanctions in connection with alleged violations of regulatory requirements that could be significant. We maintain 
general liability, contractor’s pollution liability policies (as well as additional pollution and remediation policies as needed), vehicle liability, 
employment practices liability, fiduciary liability, directors’ and officers’ liability, workers’ compensation, property, and employer’s liability 
coverages. We also maintain umbrella liability policies to provide excess coverage over the underlying limits contained in these primary policies. 
 
Regulation 
Our coal-based generation utility customers are subject to various federal, state, and local environmental laws and regulations. Our 
operations and services for these utility customers are subject to many of the same environmental laws and regulations that govern the host 
utility site. These environmental laws and regulations, among other things, impose limits on the discharge of pollutants into the air and water, 
and they establish requirements for the treatment, storage, and disposal of solid and hazardous materials, remediation of releases of hazardous 
substances, and reclamation of land. Compliance with applicable environmental laws and regulations adds to the cost of doing business. 
Moreover, to establish and operate power plants and collect, transport, and manage CCRs, our customers and we have obtained various 
federal, state, and local environmental permits. We must comply with these permits or processes and procedures approved by regulatory 
authorities. Any failure to comply with these laws or regulations, permits, or processes and procedures could result in the issuance of substantial 
fines and penalties or other sanctions and may cause us (or our customers) to incur environmental or reclamation liabilities or subject us (or our 
customers) to third-party claims. 
We generally perform our remediation and compliance and byproduct service offerings on-site at the host utility power plant. As such, 
the utility holds permits for our operational activities performed on-site. We secure any necessary permits at facilities that we own or lease. 
Despite the safeguards we follow, our operations entail risks of regulatory noncompliance or releases of hazardous substances that 
could create an environmental liability.

Regulations Affecting the Company 
Our service offerings are subject to environmental laws and regulations that can increase operating costs and give rise to increased risk 
of regulatory noncompliance and environmental liabilities. 
•    Resource Conservation and Recovery Act. RCRA Subtitle C regulates the handling, transporting, and disposing of hazardous waste. 
RCRA Subtitle D regulates non-hazardous wastes and delegates authority to states to develop solid waste programs. In 1991, the 
EPA issued final regulations under RCRA Subtitle D, which set forth minimum federal performance and design criteria for municipal 
solid waste garbage landfills. In 2015, the EPA published regulations under RCRA Subtitle D for CCRs generated by the electric 
utility industry. Subtitle D municipal solid waste regulations are implemented by the states, although states can impose more 
stringent requirements than the Subtitle D standards. The CCR Rule regulates the disposal of CCRs under RCRA Subtitle D as 
non-hazardous wastes, as discussed below. 
•    EPA CCRs Rule. As a CCR, coal ash had previously mainly been exempted from regulation under the RCRA by the “Bevill 
amendment” and, therefore, was subject to state-level solid waste regulations. However, after a major spill at a Tennessee Valley 
Authority site in Tennessee in 2008, the EPA began a rulemaking process to regulate CCRs. That process ended with the 
publication in April 2015 of the CCR Rule to regulate the disposal of CCRs, including fly ash, bottom ash, and flue gas 
desulfurization products generated at coal-fired power plants. The CCR Rule, among other things, regulates CCRs as 
non-hazardous waste and imposes new standards for location, groundwater monitoring, and dam stability on surface impoundments 
and requires long-term monitoring of existing and new surface impoundments and landfill facilities. The CCR Rule also preserves an 
exemption for CCRs when used for beneficial purposes. In March 2018, the EPA issued proposed Phase-1 1-Part rules to 
reconsider certain sections of the CCR Rule. In July 2018, the EPA issued a final Phase-1 1-Part rule to modify the CCR Rule to 
establish the program to grant states authorization with approved CCR permit programs under the Water Infrastructure 
Improvements for the Nation Act (the “WIIN Act”). The Phase-1 1-Part rule also allows CCRs to be used during certain closure 
situations and addresses certain matters remanded to the EPA by the D.C. Circuit Court of Appeals in June 2016. The EPA intends 
to reconsider and propose additional regulations to address litigation decisions by courts related to CCRs. 
•    WIIN Act. In December 2016, Congress passed the WIIN Act, which, among other things, establishes state primacy for enforcement 
of the CCR Rule. The WIIN Act directed the EPA to provide guidance to states on issuing state regulations to manage the CCR 
program. The EPA published the Coal Combustion Residuals State Permit Program Guidance Document (Interim Final) in August 
2017. States may now submit their regulatory programs for CCRs and receive EPA approval provided they are equivalent to or more 
stringent than federal guidelines. As noted above, the rule finalized by the EPA in July 2018 further implements the WINN Act's 
objectives by allowing states or the EPA to incorporate flexibilities into their coal ash permit programs. 
•Groundwater Protection. On January 11, 2022, the EPA took action to enforce the CCR Rule to expand and strengthen the regulation 
for coal ash and groundwater management of regulatory mandated surface impoundments and landfills for CCRs. The announced 
plans re-state the EPA’s consistently held position that surface impoundments or landfills cannot be closed with coal ash in contact 
with groundwater and provide for enforcement mechanisms for the regulation. The EPA rule provided remediation and closure 
criteria for leaking ash ponds, criteria for the location of new ash ponds, and water regulations on power plant discharges, resulting 
in approximately 1,000 regulatory mandated surface impoundments that needed to be remediated or closed. In addition, the EPA 
announced proposed decisions on requests for extensions to the current deadline for initiating closure of unlined CCR surface 
impoundments and accelerating plans to close coal ash ponds at plants in four states. This new rule will continue the increase in 
environmental management costs for many industry participants. 
The CCR Rule affirms that beneficial uses of CCRs remain exempt from federal waste regulation under the RCRA’s “Bevill amendment.” 
The regulation defines beneficial use as where CCRs provide a functional benefit, substitute for the use of virgin material, meet the product 
specifications, follow established specifications for use, and are environmentally equivalent to the material that they substitute for or are below all 
thresholds for safety and environmental impact. In February 2014, the EPA released a report determining that the use of fly ash in concrete 
constitutes a beneficial use, and the CCR Rule notes explicitly that the incorporation of fly ash in concrete, as a replacement for Portland 
cement, is one of “the most widely recognized beneficial applications” of CCRs. The CCR Rule indicates that the use of CCRs in applications 
such as road base generally would qualify as beneficial use, so long as relevant regulations and guidelines are followed. 
Both industry and environmental organizations have challenged the CCR Rule. The D.C. Circuit Court of Appeals has ruled on several 
cases involving CCRs. The D.C. Circuit Court remanded certain provisions of the CCR Rule back to the EPA 
9

 
 
to address through modification of the rules. The D.C. Circuit decision has indicated that CCR disposal or storage units that have only clay liners 
are not protective, and the EPA must now address the impacts of this decision on the CCR rules. 
In September 2016, the U.S. Commission on Civil Rights (the “Civil Rights Commission”) issued a report which determined that CCR 
disposal facilities can negatively impact environmental justice communities. While the Civil Rights Commission cannot require changes to EPA 
regulations, environmental organizations may seek to use the Civil Rights Commission’s report to spur the EPA to make regulatory changes. 
In July 2018, the EPA issued a final rule extending the deadline for the closure of certain impoundments and adopting other substantive 
changes. In August 2018, the D.C. Circuit Court of Appeals vacated and remanded portions of the CCR Rule. In December 2019, the EPA 
addressed the deficiencies identified by the court and proposed amendments to change the closure deadline to August 31, 2020, but allow 
certain extensions. The EPA extended the comment period on this legacy CCR surface impoundment advance notice of proposed rulemaking 
through February 23, 2022 on three proposals and until March 25, 2022 on a fourth proposal. 
Regulations Affecting the Coal Industry 
The services offerings are dependent upon managing CCRs produced by our customers, typically coal-fired power plants. Coal-fired 
power plants and the coal industry are generally highly regulated under federal and state law. Regulation affecting this industry is ever-evolving, 
including the following: 
•    Clean Air Act. The federal Clean Air Act of 1970 and subsequent amendments, particularly the Clean Air Act Amendments of 1990 
(as amended, the "CAA"), and corresponding state laws and EPA regulations (discussed below), regulate the emission of air 
pollutants such as SOx, NOx, particulate matter (“PM”), and ozone. The EPA finalized more stringent ambient air quality standards 
for fine PM in January 2013 and ozone in October 2015 and issued a final policy assessment for NOx in April 2017 and a draft policy 
assessment for SOx in August 2017. The EPA concluded that the current primary NOx standard is adequate, but has not taken 
additional steps concerning the SOx standards. Utilities have been required to make changes, such as changing fuel sources, 
installing expensive pollution control equipment, and, in some cases, shutting down plants to meet EPA emissions limits. On 
January 20, 2021, the current administration issued an executive order directing all federal agencies to review and take action to 
address any federal regulations, orders, guidance documents, policies and any similar agency actions promulgated during the prior 
administration that may be inconsistent with the administration’s policies. As a result, the degree to which certain recent regulatory 
developments may be modified or rescinded is unclear. The executive order also established an Interagency Working Group on the 
Social Cost of Greenhouse Gases (“Working Group”), which is called on to, among other things, develop methodologies for 
calculating the “social cost of carbon,” “social cost of nitrous oxide” and “social cost of methane.” The Working Group filed its final 
recommendations on January 25, 2022. with the public comment period ending on February 15, 2022. The recommendations are 
currently undergoing external scientific peer review managed by a contractor of the EPA. Further regulation of air emissions and 
uncertainty regarding the future course of regulation could eventually reduce the coal demand. 
•National Ambient Air Quality Standards. The CAA requires the EPA to set National Ambient Air Quality Standards (“NAAQS”) for six 
pollutants considered harmful to public health and the environment (“criteria pollutants”). Areas that are not in compliance with these 
standards are considered “non-attainment areas.” In recent years, the EPA has adopted more stringent NAAQS for these criteria 
pollutants that could directly or indirectly impact coal plants by designing new non-attainment areas. This could prompt local 
changes to permitting or emissions control requirements, as prescribed by federally mandated state implementation plans that 
require emission source identification and emission reduction plans. Final rules may require significant investment in emissions 
control technologies by our customers in the electric power generation industry and could affect coal demand. For example, in 2015, 
the EPA finalized the NAAQS for ozone pollution and reduced the limit to 70 parts per billion (ppb) from the previous 75 ppb 
standard. The final rule was challenged in the D.C. Circuit. On April 7, 2017, the EPA advised the D.C. Circuit that it intended to 
reconsider the final rule, and the Court subsequently stayed the litigation pending further action by the EPA. In August 2018, the 
EPA ultimately decided not to revisit the rule. As a result, the D.C. Circuit lifted its stay of the 2015 ozone NAAQS rule imposing the 
70 ppb ambient air quality standard while the EPA reviews the standards under an expedited review process. On October 31, 2019, 
the EPA published a draft policy assessment recommending that the 70 ppb ozone NAAQS be retained. In December 2020, the 
EPA retained without changes these current NAAQS standards. However, as noted above, on January 20, 2021, the current 
administration issued an executive order directing federal agencies to review and take action to address any federal regulations or 
similar agency actions promulgated during the prior administration that may be inconsistent with the current administration’s stated 
priorities. On October 29, 2020, 
 
10

 
 
the EPA determined that California, Connecticut, New York, Pennsylvania, and Texas did not submit a State Implementation Plan 
(SIP) revision which satisfied the CAA’s reasonably available control technology (RACT) requirements with regard to ozone 
standards. The EPA’s findings trigger a 24-month deadline for the EPA approve the respective SIP or finalize a Federal 
Implementation plan which addresses the deficiencies. 
•    Cross-State Air Pollution Rule. In July 2011, the EPA adopted the Cross-State Air Pollution Rule (the “CSAPR”), a cap-and-trade 
type program requiring utilities to make substantial reductions in SO2 and NOx and emissions that contribute to ozone and in fine 
PM emissions to reduce interstate transport of such pollution. The CSAPR was challenged and vacated by the D.C. Circuit Court of 
Appeals in August 2012, but the U.S. Supreme Court reversed that decision in April 2014. The D.C. Circuit has since lifted its stay 
on the CSAPR and ruled in favor of the EPA on the remaining significant issues. In January 2016, the EPA filed a brief with the D.C. 
Circuit addressing the remaining legal challenges left undecided by the U.S. Supreme Court’s 2014 decision. Conforming with a 
court-ordered schedule, the EPA implemented the first phase of the CSAPR in 2015 and 2016 and the second phase in 2017. In 
November 2014 and January 2015, the EPA issued notices of data availability outlining emission allowance allocations for existing 
generating units that began operating before and after 2010. In September 2016, the EPA finalized a rule updating the CSAPR to 
maintain 2008 ozone emission limitations in downwind states by addressing summertime (May-September) transport of ozone 
pollution (the "CSAPR Update"). The CSAPR Update, which commenced in May 2017, sets stricter NOx ozone season emission 
budgets in 22 states and could affect up to 886 coal-fired facilities. For both NOx and SO2, these emission control requirements can 
impact the quantity and quality of CCRs produced at a power plant, add to the costs of operating a power plant, and make coal a 
less attractive fuel alternative in the planning and building of utility power plants. On December 6, 2018, the EPA issued the CSAPR 
“Close-Out” Rule, a final determination that the CSAPR achieves concerning the 2008 ground-level ozone NAAQS in 20 states. 
Accordingly, those states will not be required to impose requirements for further reduction in transported ozone pollution. The 
covered states do not need to submit state implementation plans to establish additional requirements beyond the existing CSAPR 
Update. Several states and other entities challenged the CSAPR Close-Out Rule in the D.C. Circuit. In a September 13, 2019 ruling, 
the D.C. Circuit remanded the CSAPR Update to the EPA, finding that rule is inconsistent with the CAA. In a subsequent October 1, 
2019 ruling, the CSAPR Close-Out Rule was vacated. On March 15, 2021, the EPA finalized its Revised CSAPR Update Rule to 
address 21 states’ outstanding interstate pollution transport obligations for the 2008 NAAQS. Starting in the 2021 ozone season, the 
rule requires additional emissions reductions of NOx from power plants in 12 states. The CSAPR Update Rule will affect the demand 
for coal. 
•    Comprehensive Environmental Response, Compensation and Liability Act. Certain environmental laws, including the Comprehensive 
Environmental Response, Compensation and Liability Act (the “CERCLA”) and similar state laws, impose strict, joint and several 
liability on responsible parties for the investigation and remediation of regulated materials at contaminated sites, including our sites, 
customer sites, and sites to which we sent wastes, including CCRs. CCRs may contain materials such as metals that are regulated 
materials under these laws. Management of CCRs can give rise to liability under the CERCLA and similar laws. 
•    Mercury and Air Toxics Standards for Power Plants. In February 2012, under its Mercury and Air Toxics Standards for Power Plants 
rule, the EPA promulgated final limits on mercury and other toxic chemicals from new and modified power plants. In June 2015, the 
U.S. Supreme Court ordered the EPA to undertake a cost-benefit analysis when promulgating mercury and air toxics standards. In 
April 2016, the EPA published a supplemental finding pursuant to the U.S. Supreme Court’s directive, currently being challenged in 
the D.C. Circuit. In April 2017, the D.C. Circuit granted the EPA’s motion to stay the litigation while the EPA reconsiders its finding 
that the rule is “appropriate and necessary” as required under the Clean Air Act. If upheld, requirements to control mercury 
emissions could result in the implementation of additional technologies at power plants that could negatively affect fly ash quality. 
•    GHG Emissions. Some states and regions have adopted legislation and regulatory programs to reduce GHG emissions, either 
directly or through mechanisms such as renewable portfolio standards for electric utilities. These programs require electric utilities to 
increase their use of renewable energy, such as solar and wind power. Federal GHG legislation appears unlikely in the near term. 
The EPA has initiated a review of rules finalized in August 2015 for GHG emissions from new and existing fossil fuel-fired electric 
power plants and for carbon emissions from existing sources in the power sector (the latter being known as the “Clean Power Plan”). 
The Clean Power Plan establishes state-specific, rate-based reduction goals for carbon emissions and calls on the power sector to 
reduce carbon emissions to 32% below 2005 levels by 2030. 
11

 
 
On June 19, 2019, the EPA finalized the Affordable Clean Energy ("ACE") rule to replace the Clean Power Plan. The ACE rule 
establishes emission guidelines for states to develop plans to address greenhouse gas emissions from existing coal-fired power 
plants. The ACE rule has several components: a determination of the best system of emission reduction for greenhouse gas 
emissions from coal-fired power plants, a list of “candidate technologies” states can use when developing their plans, a new 
preliminary applicability test for determining whether a physical or operational change made to a power plant may be a “major 
modification” triggering New Source Review, and new implementing regulations for emission guidelines under Clean Air Act section 
111(d). On February 19, 2021, the current administration rejoined the Paris Agreement. Regardless of the extent to which the United 
States ultimately participates in these reductions, participation in the Paris Agreement framework could reduce the overall demand 
for coal over the long term. 
In December 2015, 195 nations (including the United States) signed the Paris Agreement, a long-term, international framework 
convention designed to address climate change over the next several decades. This agreement entered into force in November 
2016 after more than 70 countries, including the United States, ratified or otherwise agreed to be bound by the agreement. The 
United States was among the countries that submitted its declaration of intended greenhouse gas reductions in early 2015, stating 
its intention to reduce U.S. greenhouse gas emissions by 26-28% by 2025 compared to 2005 levels. Whether and to what extent the 
United States meets its stated intention likely depends on several factors, including whether the ACE rule is implemented. In June 
2017, the Trump administration announced the United States' intention to withdraw from the Paris Agreement. In November 2019, 
the Trump administration formally initiated the withdrawal process and formally exited the Agreement on November 4, 2020. In 
January 2021, the current administration issued an executive order commencing the process to reenter the Paris Agreement, 
although the emissions pledges connected with that effort have not yet been updated. Regardless of the extent to which the United 
States ultimately participates in these reductions, participation in the Paris Agreement framework could reduce the overall demand 
for coal over the long term. 
Several U.S. states have enacted legislation establishing greenhouse gas emissions reduction goals or requirements or joined 
regional greenhouse gas reduction initiatives. Some states have also enacted legislation or regulations requiring electricity suppliers 
to use renewable energy sources to generate a certain percentage of power or that provide financial incentives to electricity 
suppliers to use renewable energy sources. For example, eleven northeastern states are current members of the Regional 
Greenhouse Gas Initiative, a mandatory cap-and-trade program established in 2005 to cap regional carbon dioxide emissions from 
power plants. Six Midwestern states and one Canadian province entered into the Midwestern Regional Greenhouse Gas Reduction 
Accord to establish voluntary regional greenhouse gas reduction targets and develop a voluntary multi-sector cap-and-trade system 
to help meet the targets. However, it has been reported that the members no longer are actively pursuing the group’s activities. 
Lastly, California and Quebec remain members of the Western Climate Initiative, formed in 2008 to establish a voluntary regional 
greenhouse gas reduction goal and develop market-based strategies to achieve emissions reductions. Those two jurisdictions have 
adopted their own greenhouse gas cap-and-trade regulations. Several states and provinces that initially were members of these 
organizations and some current members have joined the new North America 2050 initiative, which seeks to reduce greenhouse gas 
emissions and create economic opportunities aside from cap-and-trade programs. Any particular state, or any of these or other 
regional groups, may have or adopt future rules or policies that cause some coal users to switch from coal to a lower carbon fuel. 
There can be no assurance at this time that a carbon dioxide cap-and-trade-program, a carbon tax or other regulatory or policy 
regime, if implemented by any one or more states or regions in which our customers operate or at the federal level, will not affect the 
future market for coal in those states or regions and lower the overall demand for coal. 
•    EPA Water Quality Regulations. The EPA is addressing water quality impacts from coal-fired power plants and coal mining 
operations. To obtain a permit for certain coal mining activities, including the construction of coal refuse areas and slurry 
impoundments that may result in impacts to waters of the United States, an operator may need to obtain a permit for the discharge 
of fill material from the Army Corps of Engineers (“ACOE”) under Section 404, as well as a corresponding permit from the state 
regulatory authority under Section 401 of the CWA. All permits associated with the placement of dredged or fill material subject to 
minimum thresholds require appropriate mitigation. Permit holders must receive explicit authorization from the ACOE before 
proceeding with mining activities. In September 2015, the EPA finalized new effluent limitations (the "Clean Water Rule") under the 
Clean Water Act for steam electric power generating facilities. The final rule requires coal plant operators with a generating capacity 
of over 50 megawatts to store fly ash and bottom ash in dry landfills rather than containment ponds. Approximately 12% of coal 
plants will be affected, and some marginal operations may shut down rather than face the expense of complying with the Clean 
Water Rule. Multiple challenges to the Clean Water Rule were 
12

 
 
consolidated and are pending before the Court of Appeals for the Fifth Circuit. On February 28, 2017, President Trump issued an 
executive order prompting the EPA and ACOE to consider replacing the blocked Clean Water Rule. On December 11, 2018, the 
EPA and the ACOE proposed a new regulation to determine which waterbodies are subject to federal jurisdiction. A final rule 
repealing the 2015 definition of “Waters of the United States” ("WOTUS") became effective on December 23, 2019. 
In December 2018, the EPA and ACOE also formally proposed a new rule revising the definition of WOTUS. The new rule -- the 
Navigable Waters Protection Rule -- became effective on June 22, 2020, and substantially reduces the scope of waters that fall 
within the Clean Water Act’s jurisdiction, in part by excluding ephemeral streams, which potentially qualified as “Waters of the United 
States” under the 2015 WOTUS rule. The repeal of the 2015 WOTUS rule and the implementation of the pre-2015 rule have been 
challenged in federal courts, as has the Navigable Waters Protection Rule, which is currently subject to a challenge in at least twelve 
federal district courts. A federal district court issued a preliminary injunction preventing the Navigable Waters Protection Rule from 
taking effect in Colorado, but the rule is otherwise effective in every other state. In addition, in April 2020, the U.S. Supreme Court 
issued a decision finding that point source discharges to navigable waters through groundwater are subject to regulation under the 
Clean Water Act. The U.S. Supreme Court specifically held that the Clean Water Act requires a permit if the addition of the 
pollutants through groundwater is the “functional equivalent” of a direct discharge from the point source into navigable waters. As a 
result of such recent developments, substantial uncertainty exists regarding the scope of waters protected under the Clean Water 
Act and the discharges to such waters that are subject to permit requirements. Should the State of Colorado’s challenge to the new 
definition of “Waters of the United States” be unsuccessful, or should the new Biden administration further modify the definition, 
operators could incur increased costs or delays with respect to obtaining permits for such activities as dredge and fill operations. 
These more stringent regulations of coal-fired power plants and coal mining operations could increase the costs for utilities and, 
thus, indirectly impact the availability and cost of fly ash for our CCR activities. 
Increasingly strict requirements, such as those described above, will generally increase the cost of doing business and may make 
burning coal less attractive for utilities. Faced with the prospect of more stringent regulations, litigation by environmental groups, and the 
relatively low cost of natural gas, an increasing number of electric utilities are reducing their portfolio of coal-fired power plants. For example, in 
recent years, multiple companies have closed coal-fired power plant units or plants or dropped plans to open new coal-fired plants, citing the 
cost of compliance with pending or new environmental regulations and the relatively low cost of natural gas. The potential negative impact on job 
prospects in the utility and mining industries has prompted considerable concern in Congress, leading to calls to restrict the EPA’s regulatory 
authority and prompting the EPA to reconsider the same. The outcome of these developments cannot be predicted. If the rate of coal-fired power 
plant closures increases, our business, financial condition and results of operations may be adversely affected. Nevertheless, we believe that 
reliance on coal for a substantial amount of power generation in the United States is likely to continue for the foreseeable future. 
Motor Carrier Operations 
Through the services we provide, we operate as a motor carrier and are subject to regulation by the U.S. Department of Transportation 
(the “DOT”) and various state agencies. These regulatory authorities exercise broad powers governing activities, such as the authorization to 
engage in motor carrier operations; regulatory safety; hazardous materials labeling, placarding, and marking; financial reporting; and certain 
mergers, consolidations, and acquisitions. Additional regulations specifically relate to the trucking industry, including testing and specification of 
equipment and product handling requirements. The trucking industry is subject to possible regulatory and legislative changes that may affect the 
industry's economics by requiring changes in operating practices or by changing the demand for common or contract carrier services or the cost 
of providing truckload services. Some of these possible changes include increasingly stringent environmental regulations, changes in the hours 
of service regulations that govern the amount of time a driver may drive in any specific period, and requiring onboard black box recorder devices 
or limits on vehicle weight and size. 
Interstate motor carrier operations are subject to safety requirements prescribed by the DOT. Intrastate motor carrier operations are 
subject to safety requirements that often mirror federal regulations. Such matters as weight and dimension of equipment are also subject to 
federal and state regulations. DOT regulations also mandate drug testing of drivers. From time to time, various legislative proposals are 
introduced, including proposals to increase federal, state, or local taxes, including taxes on motor fuels, which may increase our costs or 
adversely impact the recruitment of drivers. We cannot predict whether, or in what form, any increase in such taxes applicable to us will be 
enacted.

Human Capital Resources 
As of December 31, 2021, we had approximately 693 employees. Approximately 90 of our employees were covered by collective 
bargaining agreements. We believe we have good relations with our employees. We have 56 employees (more than 8.0% of all employees) with 
ten or more years of seniority working at the Company. 
The Company is an Equal Opportunity Employer. We will consider all qualified applicants for employment without regard to race, color, 
religion, sex, sexual orientation, gender identity, national origin, or protected veteran status, and we will not discriminate against any qualified 
candidate based on disability. 
Each eligible employee receives a comprehensive benefits package that includes full healthcare coverage, 100% paid preventive care, 
dental, vision, life insurance, short- and long-term disability, paid time off, and 401(k) with company contribution. We understand the importance 
of keeping our employees safe and healthy. 
Health and Safety 
Safety is one of our core values. We are dedicated to maintaining a safe working environment and training our employees and 
subcontractors to perform their jobs safely and proactively contribute to a safe workplace. 
A vital principle of the Charah Way involves actively caring for those around us and working together as one team. Caring for our 
coworkers and acting as a team is a crucial part of working safely. It requires us to coach and be coached when unsafe behaviors are identified 
or observed. Safety is not one person’s responsibility; we believe safety is everyone’s responsibility as well as being there for one another in 
times of crisis. 
Charah Solutions recently passed a one-year safety milestone with 1.25 million person-hours of work without an Occupational Safety 
and Health Administration (“OSHA”) recordable incident. Another significant milestone is that Charah has worked without a lost-time event since 
April 17, 2019 and logged more than 3 million person-hours. These significant achievements are a result of the commitment of all personnel to 
put safety first. 
Our record in safety excellence also includes the following achievements: 
•We accomplished a 0.32 Recordable Incident Rate in 2021 with no lost time or restricted time injuries in comparison to the most recent 
industry Recordable Incident Rate industry average of 3.1;

    Our Managers and Safety Specialists team utilize an advanced predictive analytics tool to document, monitor, and track behaviors and 
conditions. This tool utilizes observations, incidents, and historical event data to provide valuable information that we thoroughly assess. We 
provide our site, regional, and executive leadership "dashboards" that detail incident and observation data from the previous week, month, and 
year and identify particular trends in that data. We use this information to customize plans to mitigate hazards and reverse any negative trends 
aggressively. We also use this data, along with other analytical data at the project level to compare statistical data across regions and job sites. 
Over the last five years, our team has completed over 40,000 inspections and 1.9 million observations, with more than 23,000 opportunities for 
improvement identified. 
Recent award recognition for our focus on Safety Leadership includes: 
•AGC Willis Towers Watson Construction Safety Excellence Award for the fifth straight year, including being named the winner of the

Item 1A. Risk Factors 
 
Risks Related to Our Business 
A decline in the production of CCRs by our coal-fired utility industry customers due to environmental regulations or otherwise could 
negatively impact our profitability and hinder our growth. 
Many of our services are dependent upon the production of CCRs by our coal-fired utility industry customers. The coal-fired utility 
industry faces several new and pending initiatives by regulatory authorities seeking to address air and water pollution, GHG emissions, and the 
management and disposal of CCRs. In recent years, federal and state environmental regulations have imposed more stringent requirements 
regarding the emission of air pollutants and other toxic chemicals, reduction of GHG emissions, and water quality impacts from coal operations. 
Adoption of more stringent regulations governing coal combustion, water discharges, or air emissions may decrease the amount of CCRs 
produced by our customers and, as a result, the demand for our services. Faced with the prospect of more stringent regulations, litigation by 
environmental groups, and the relatively low cost of natural gas, an increasing number of electric utilities are reducing their portfolio of coal-fired 
power plants. The pace of the reduction may increase due to changes in the U.S. executive administration, Congressional leadership and 
regulatory agency leadership. This reduction could cause states to substitute electricity generation from higher-emitting coal plants with 
low-emitting coal and natural gas plants and zero-emitting renewable sources. See “Item 1. Business—Regulation.” 
Increasingly strict requirements generally will increase the cost of doing business and may make burning coal less attractive for utilities. 
In recent years, multiple companies have announced plans to close coal-fired power plant units or plants or dropped plans to open new plants, 
citing the cost of compliance with pending or new environmental regulations and the relatively low cost of natural gas. A reduction in coal use as 
fuel would cause a decline in the production and availability of CCRs, which would adversely affect our byproduct services offerings and result in 
reduced revenue. The outcome of these developments cannot be predicted but could have a material adverse effect on our business, results of 
operation, financial condition, and cash flows. 
The COVID-19 pandemic and any future major public health crisis could disrupt the Company's operations and adversely impact its 
business, results of operations and financial conditions. 
The COVID-19 pandemic, including new and emerging strains and variants, continues to have adverse effects on the U.S. and global 
economies. This outbreak has adversely affected workforces, customers, economies, supply chains, and global transportation and financial 
markets. While the Company has not incurred significant disruptions thus far from the COVID-19 pandemic, the pandemic and any future major 
public health crisis could impact our business, consolidated results of operations and financial condition in the future. For example, our business 
and results of operations could be materially adversely affected if significant portions of our workforce are unable to work effectively, whether it is 
due to illness, quarantines, government actions or other restrictions in connection with the COVID-19 pandemic or any future major public health 
crisis. However, the significance of the impact on our operations going forward is not yet certain and depends on numerous evolving factors that 
the Company may not be able to accurately predict or effectively respond to, including, without limitation: the COVID-19 pandemic or any future 
major public health crisis, actions taken by governments, businesses and individuals in response, the effect on economic activity and actions 
taken in response, the effect on customers and their demand for the Company’s products and services and the timing of such demand, the 
ability of our subcontractors to perform under their contracts due to their own financial or operational difficulties, the availability of subcontractors 
and other talent, the speed and effectiveness of responses to combat the COVID-19 virus or any future major public health crisis, including 
vaccine efficacy, distribution and widespread public acceptance, and the Company’s ability to continue operations, including without limitation as 
a result of supply chain challenges, facility closures, social distancing, restrictions on travel, fear or anxiety by the populace and shelter-in-place 
orders. 
Our business, financial condition and results of operations depend on the award of new contracts and the timing of the performance of 
these contracts. 
We derive our revenue from the performance of customer contracts which itself is dependent on new contract awards. Reductions in the 
number and amounts of new awards, delays in the timing of the awards, or potential cancellations of such awards resulting from economic 
conditions, material and equipment pricing, and availability or other factors could adversely impact our business, financial condition and results 
of operations. It is particularly difficult to predict whether or when we will be awarded large-scale projects as these contracts frequently involve a 
lengthy and complex bidding and selection process that is affected by market conditions as well as regulatory requirements. We have 
experienced difficulty in the timely award of new projects and may again in the future. Because we generate our revenue from such projects, our 
results of operations and cash flows can fluctuate significantly from quarter to quarter depending on the timing of our contract awards and the 
commencement and progress of work under awarded contracts. Also, many of these contracts are subject to financing contingencies. As a 
result, we are subject to the risk that the customer will not be able to secure the necessary financing for a project to proceed. If we are 
 
16

 
 
unable to secure the awards of new contracts, our business, financial condition and results of operations will be adversely affected. 
We may lose existing contracts through competitive bidding or early termination. 
Many of our contracts are for a specified term and are subject to competitive rebidding after the term for such contract expires. Although 
we intend to bid to extend expiring contracts, we may not always be successful. Also, some or all of our customers may terminate their contracts 
with us before their scheduled expiration dates. If we are not able to replace lost revenue resulting from unsuccessful competitive bidding, early 
termination, or the renegotiation of existing contracts with other revenue within a reasonable period, our business, financial condition and results 
of operations could be adversely affected. 
We could be precluded from entering into or maintaining permits or certain contracts if we are unable to obtain sufficient third-party 
financial assurance or adequate insurance coverage. 
Our operations sometimes require us to obtain performance or surety bonds, letters of credit, or other means of financial assurance to 
secure our contractual performance. We currently obtain performance and surety bonds from multiple financial institutions; however, if we are 
unable to obtain financial assurance in the future in sufficient amounts from appropriately rated sureties or on acceptable terms, we could be 
precluded from entering into certain additional contracts or from obtaining or retaining landfill management or other contracts or operating 
permits. Any future difficulty in obtaining insurance could also impair our ability to secure future contracts conditioned upon having adequate 
insurance coverage. 
Unsatisfactory service and safety performance may negatively affect our customer relationships and, to the extent we fail to retain 
existing customers or attract new customers, adversely impact our revenue. 
Our ability to retain existing customers and attract new business is dependent on many factors, including our ability to demonstrate that 
we can reliably and safely operate our business in a manner that is consistent with our customers’ standards of service as well as applicable 
laws, rules, and permits, which are subject to change. Existing and potential customers consider the safety and service record of their third-party 
service providers to be of high importance in their decision to engage such providers. The power generation industry generally emphasizes 
safety and service over cost due to economic and reputational risk associated with operations at their facilities. 
We may experience multiple or particularly severe accidents in the future, causing our safety record to deteriorate. This possibility may 
be more likely as we continue to grow, if we experience high employee turnover or a labor shortage or hire inexperienced personnel to support 
our staffing needs. If one or more accidents were to occur while we are providing services to our customers, or if we were unable to maintain the 
level of safety and service our customers require, the affected customer may seek to terminate our services and may be less likely to use our 
services in the future, which could adversely affect our business, financial condition and results of operations. Furthermore, our ability to attract 
new customers may be impaired if they view our safety or service record as unacceptable. 
Our ERT services will require us to acquire significant real property and assume liabilities that could adversely impact our future results. 
As part of our ERT services, we will purchase real and personal property and assume environmental liabilities. We will plan to sell these 
acquired assets to third parties. However, the timing of these future dispositions is difficult to predict, and we may not be able to realize the gains 
on sales as anticipated. If we cannot sell these assets, the assets may be written down to their fair value, with the impairment loss recognized as 
a non-cash charge in the consolidated statement of operations. Furthermore, these services will require us to assume environmental liabilities 
with long-term monitoring requirements. If actual costs exceed our cost estimates, we may incur future additional liabilities, which could 
adversely impact our results of operations. 
The loss of a large customer may adversely affect our revenue and operating results. 
We will likely continue to derive a significant portion of our revenue from a relatively small number of customers in the future. If a major 
customer fails to pay us promptly or at all, our revenue would be negatively impacted, and our operating results, financial condition and cash 
flows could be materially adversely affected. Additionally, if we were to lose any material customer, such loss would have a material adverse 
effect on our business and results of operations. 
We and our customers operate in industries subject to significant environmental regulation, and compliance with changes in, or liabilities 
under, such regulations could add significantly to the costs of conducting business. 
Our operations and the operations of our customers are subject to federal, state, and local environmental laws and regulations that, 
among other matters, impose limitations on the discharge of pollutants into the air and water and establish standards for the treatment, storage, 
and disposal of solid, hazardous, and radioactive waste materials, the remediation of releases of hazardous substances, and the reclamation of 
land. We and our customers have obtained various federal, state, and 
 
17

 
 
local environmental permits to conduct our operations, and we must comply with these permits and processes and procedures regulatory 
authorities have approved. Any failure to comply with these environmental requirements could give rise to sanctions, including, but not limited to: 
i) the cessation of all or part of our operations, ii) substantial fines and penalties, iii) environmental or reclamation liabilities, which liabilities may 
be strict and joint and several and iv) damages, including natural resource damages in connection with our sites, customer sites, or sites to 
which we sent wastes, including CCRs, and third-party claims. Moreover, changes in environmental laws and regulations occur frequently, and 
any changes that result in more stringent or costly environmental requirements could require our customers or us to make significant 
expenditures to attain and maintain compliance. New regulations, failure to comply with existing regulations, or environmental liabilities arising 
thereunder could have a material adverse effect on our business, results of operation, financial condition, and cash flows. 
Success by environmental groups in convincing the EPA to restrict beneficial uses of CCRs, or to regulate CCRs as hazardous waste, 
may have an adverse effect on our business. 
In April 2015, the EPA published the CCR Rule to regulate the disposal of CCRs, including fly ash and bottom ash generated at 
coal-fired power plants, as non-hazardous waste under Subtitle D of the RCRA and to distinguish the beneficial use of CCRs from disposal, 
which became effective in October 2015. The CCR Rule establishes national minimum criteria for CCR landfills and impoundments consisting of 
location restrictions, design and operating criteria, groundwater monitoring and corrective action, closure requirements, post-closure care, 
recordkeeping and reporting and other requirements, and requires closure of facilities unable to comply with these criteria within five to seven 
years. The CCR Rule has increased the complexity and cost of managing and disposing of CCRs and remediating existing ash ponds and 
landfills. Also, Congress passed the WIIN Act in December 2016, which, among other things, authorizes state permit programs to manage CCRs 
in place of the CCR Rule. The WIIN Act also gives the EPA the authority to regulate coal ash in states that choose not to implement state 
permitting programs and in states whose permitting programs are determined to be inadequate by the EPA. In July 2018, the EPA issued a final 
rule that would take further steps under the WIIN Act by granting states with approved CCR permit programs (or the EPA where it is the 
permitting authority) the ability to set specific alternative performance standards. The rule would also allow CCRs to be used during certain 
closure situations. Finally, it addresses certain matters remanded to the EPA by the D.C. Circuit Court of Appeals in June 2016, including 
clarifying corrective action triggers and requirements, adding boron to the list of constituents triggering corrective action, determining the proper 
height of woody and grassy vegetation for slope protection, and modifying alternative closure procedures. In August 2018, the D.C. Circuit Court 
of Appeals vacated and remanded portions of the CCR Rule. In December 2019, the EPA addressed the deficiencies identified by the court and 
proposed amendments to change the closure deadline to August 31, 2020, but to allow certain extensions. The EPA extended the comment 
period on this legacy CCR surface impoundment advance notice of proposed rulemaking through February 23, 2022 on three proposals and until 
March 25, 2022 on a fourth proposal. 
Some environmental groups continue to urge the EPA to restrict certain beneficial uses of CCRs, such as in concrete, road base, and 
soil stabilization, alleging contaminants may leach into the environment. The CCR Rule created a definition of “beneficial use” that includes uses 
in concrete and road base, but changes in the definition could reduce the demand for fly ash and other CCRs, which would have an adverse 
effect on our revenue. Moreover, if the EPA were to regulate CCRs as hazardous waste, we, together with CCR generators, could be subject to 
environmental cleanup, personal injury, and other possible claims and liabilities that could result in significant additional costs. Any such changes 
in or new regulations or indemnity obligations could have a material adverse effect on our business, results of operation, financial condition, and 
cash flows. 
We may be adversely affected by uncertainty in the global financial markets and the deterioration of our customers' financial condition. If 
any of our customers suffer financial difficulties affecting their credit risk, our operating results could be negatively impacted. 
Our future results of operations may be affected by the uncertainty caused by an economic downturn, natural disaster, pandemic, 
volatility or deterioration in the capital markets or credit markets, inflation, deflation, or other adverse economic conditions that may negatively 
affect us or parties with whom we do business, resulting in a reduction in our customers’ spending and their nonpayment or inability to perform 
obligations owed to us, such as the failure of customers to honor their commitments. Additionally, downturns in U.S. construction could lower the 
demand for our byproduct services and raw material sales offerings. 
We also provide service to power generators. To the extent these entities suffer significant financial difficulties, they could be unable to 
pay amounts owed to us or to renew contracts with us on attractive terms. Our customers' inability, particularly larger customers, to pay us 
promptly or to pay increased rates could negatively affect our business, financial condition and results of operations. In addition, in the course of 
our business, we hold accounts receivable from our customers. In the event of the customer's financial distress or bankruptcy, we could lose all 
or a portion of such outstanding accounts 
18

 
 
receivable associated with that customer. Further, if a customer was to enter bankruptcy, it could result in the cancellation of all or a portion of 
our service contracts with that customer at significant expense or loss of expected revenue. 
If we are unable to accurately estimate the overall risks, revenues or costs on our projects, we may incur contract losses or achieve 
lower profits than anticipated. 
Pricing on fixed unit price contracts is based on approved quantities irrespective of our actual costs, and contracts with a fixed total price 
require that the work be performed for an agreed-upon price irrespective of our actual costs. We only generate profits on fixed unit price and 
fixed total price contracts when our revenues exceed our actual costs, which requires us to estimate our costs accurately, control our actual 
costs and avoid cost overruns. If our cost estimates are too low or we do not perform the contract within our cost estimates, then cost overruns 
may cause us to incur a loss or cause the contract not to be as profitable as we expected. As a result, these types of contracts could negatively 
affect our cash flow, earnings and financial position. 
The costs incurred and profit realized, if any, on our contracts can vary, sometimes substantially, from our original projections due to a 
variety of factors, including, but not limited to: 
•onsite conditions that differ from those assumed in the original bid or contract; 
•failure to include required materials or work in a bid, or the failure to estimate properly the quantities or costs needed to complete a 
lump sum contract; 
•delays caused by weather conditions or otherwise failing to meet scheduled acceptance dates; 
•contract or project modifications creating unanticipated costs not covered by change orders or contract price adjustments; 
•changes in availability, proximity and costs of materials, including steel, concrete, aggregates and other construction materials (such as 
stone, gravel, sand and oil for asphalt paving), as well as fuel and lubricants for our equipment; 
•higher than anticipated costs to lease, acquire and maintain equipment; 
•availability and skill level of workers in the geographic location of a project; 
•rapidly increasing labor costs; 
•the failure of our suppliers, subcontractors, designers, engineers or customers to perform their obligations; 
•fraud, theft or other improper activities by our suppliers, subcontractors, designers, engineers, customers or our personnel; 
•mechanical problems with our machinery or equipment; 
•citations issued by a government authority, including OSHA; 
•difficulties in obtaining required government permits or approvals; 
•changes in applicable laws and regulations; 
•uninsured claims or demands from third parties for alleged damages arising from the design, construction or use and operation of a 
project of which our work is part; and 
•delays in quickly identifying and taking measures to address issues that arise during the execution of a project. 
Increases in labor costs or our ability to find, employ and deploy technically skilled labor could impact our financial results. 
Our continued success will depend on our ability to attract and retain qualified personnel. We compete with other businesses in our 
markets for qualified employees. From time to time, the labor supply is tight in some of our markets. Labor is a primary component of operating 
our business. A number of factors may adversely affect the labor force available to us or increase labor costs from time to time, including high 
employment levels, federal unemployment subsidies, including unemployment benefits offered in response to the COVID-19 pandemic, and 
other government regulations. 
Although we have not experienced any material disruptions due to labor shortages to date, we have observed an overall tightening and 
increasingly competitive labor market. A sustained labor shortage or increased turnover rates within our employee base, whether caused by 
COVID-19 or as a result of general macroeconomic factors, could lead to increased costs, such as increased overtime to meet demand and 
increased wage rates to attract and retain employees, and could negatively 
 
19

 
 
affect our ability to complete our construction projects according to the required schedule or otherwise efficiently operate our business. If we are 
unable to hire and retain employees capable of performing at a high level, or if mitigation measures we may take to respond to a decrease in 
labor availability, such as overtime and third-party outsourcing, have unintended negative effects, our business could be adversely affected. In 
addition, we dispose of CCRs and distribute our raw material sales offerings to customers primarily by truck. Reduced availability of trucking 
capacity due to shortages of drivers, primarily as a result of the COVID-19 pandemic, has caused an increase in the cost of transportation for us 
and our suppliers. An overall labor shortage, lack of skilled labor, increased turnover or labor inflation, caused by COVID-19 or as a result of 
general macroeconomic factors, could have a material adverse impact on our operations, results of operations, liquidity or cash flows. 
Dependence on third-party subcontractors and equipment manufacturers could adversely affect our profits. 
We rely on third-party subcontractors and equipment manufacturers to complete many of our projects. We could experience losses to 
the extent that we cannot engage subcontractors or acquire equipment or materials or if the amount we are required to pay for these goods or 
services exceeds the amount we have estimated in bidding for fixed-price contracts in the performance of these contracts. Also, if a 
subcontractor or a manufacturer is unable to deliver its services, equipment or materials according to the negotiated terms for any reason 
including, but not limited to, the deterioration of its financial condition, we may be required to purchase the services, equipment or materials from 
another source at a higher price. This may reduce the expected profit or result in a loss on a project, negatively impacting our business, financial 
condition and results of operations. 
We service a significant portion of our contracts with our own construction equipment rather than leased or rented equipment. To the 
extent that we are unable to buy construction equipment necessary for our needs, either due to a lack of available funding or equipment 
shortages in the marketplace, we may be forced to rent equipment on a short-term basis, which could increase the costs of performing 
our contracts. 
The property, plants and equipment needed to produce our products and provide our services can be very expensive. We must spend a 
substantial amount of capital to purchase and maintain such assets. Although we believe our current cash balance, along with our projected 
internal cash flows and available financing sources, will provide sufficient cash to support our currently anticipated operating and capital needs, if 
we are unable to generate sufficient cash to purchase and maintain the property, plants and equipment necessary to operate our business, or if 
the timing of payments on our receivables is delayed, we may be required to reduce or delay planned capital expenditures or to incur additional 
indebtedness. In addition, due to the level of fixed and semi-fixed costs associated with our business, volume decreases could have a material 
adverse effect on our financial condition, results of operations or liquidity. 
Supply chain issues, including shortages of equipment, vehicles and construction supplies, could increase our costs or cause delays in 
our ability to complete our projects, which could have an adverse impact on our business and our relationships with customers. 
We rely on our supply chain for equipment, vehicles and construction supplies in order to complete our projects. A reduction or 
interruption in supply, including disruptions due to the COVID-19 pandemic, a significant natural disaster, shortages in global freight capacity, 
significant increases in the price of critical components, a failure to appropriately forecast or adjust our requirements based on our business 
needs, or volatility in demand for our products and services could materially adversely affect our business, operating results, and financial 
condition and could materially damage customer relationships. Our vendors and subcontractors also may be unable to meet our demand, 
significantly increase lead times for deliveries or impose significant price increases that we are unable to offset through alternate sources of 
supply, price increases to our customers or increased productivity in our operations. In some cases, we procure certain inputs and services from 
single or limited suppliers or subcontractors. In the event of supply disruptions from these suppliers or subcontractors, we may not be able to 
diversify our resources for such materials or services in a timely manner or may experience quality issues with alternate sources. Our growth 
and ability to meet customer demand depend in large part on our ability to obtain timely deliveries of equipment and vehicles from our suppliers, 
and significant disruptions in their supply could materially adversely affect our business, operating results, and financial condition and could 
materially damage customer relationships. 
Our employees perform services that involve certain risks, including risks of accident, and a failure to maintain a safe work site could 
result in significant losses. 
Safety is a primary focus of our business and is critical to our reputation. Our services can place our employees and others in 
challenging environments near large equipment, dangerous processes and highly toxic or caustic materials. Our operations involve risks, such 
as truck accidents, equipment defects, malfunctions and failures, and natural disasters, which could potentially result in releases of CCR 
materials, injury or death of employees and others, or a need to shut down or reduce the operation of our customers’ facilities while we 
undertake remedial actions. We are responsible for safety on the sites where we work, and these risks expose us to potential liability for pollution 
and other environmental damages, personal injury, loss of 
 
20

 
 
life, business interruption, and property damage or destruction. Unsafe work conditions also can increase employee turnover, increase costs and 
raise our operating costs. If we fail to implement appropriate safety procedures and/or our procedures fail, our employees or others may suffer 
injuries. 
 Although we maintain functional groups whose primary purpose is to implement effective health, safety, and environmental procedures 
throughout our company, the failure to comply with such procedures, client contracts, or applicable regulations could subject us to losses and 
liability and the potential loss of customers. If we were to incur substantial liabilities above any applicable insurance, our business, results of 
operations, and financial condition could be adversely affected. 
Our financial results may fluctuate from quarter to quarter due to seasonal weather patterns and other factors, making it difficult to 
predict our future performance. 
Consumption of energy is seasonal, and any variation from normal weather patterns, including due to unseasonably cooler or warmer 
weather, can have a significant impact on energy demand. Additionally, adverse weather conditions, such as hurricanes, tropical storms, and 
severe cold weather, may interrupt or curtail our operations or our customers’ operations and result in a loss of revenue and damage to our 
equipment and facilities, which may or may not be insured. 
Our byproduct services and raw material sales offerings are also subject to quarterly fluctuations from time to time. For these reasons, 
comparing our financial results on a period-to-period basis may not be meaningful, and our past results should not be relied on as an indication 
of our future performance. Our future quarterly and annual expenses as a percentage of our revenue may be significantly different from those we 
have recorded in the past or which we expect for the future. Our financial results in some quarters may fall below expectations. Changes in cost 
estimates relating to our services, which under the cost-to-cost input method of accounting principles could lead to significant fluctuations in 
revenue or changes in the timing of our recognition of revenue from such services, could cause our stock price to fall. 
We operate in a highly competitive industry and may not be able to compete effectively with larger and better-capitalized companies. 
While no specific company provides the range of services that we offer, the industries in which we operate are highly competitive and 
require substantial labor and capital resources. Some of the markets in which we compete or plan to compete are served by one or more large 
national companies and regional and local companies of varying sizes and resources, some of which may have accumulated a substantial 
reputation in their markets. Some of our competitors may also be better capitalized than we are, have greater name recognition than we do, or 
provide or be willing to bid their services at a lower price than we may be willing to offer. Our inability to compete effectively could hinder our 
growth or adversely impact our business, financial condition and results of operations. 
We rely on technology in our business, and any technology disruption or delay in implementing new technology could adversely affect 
our business, financial condition, results of operation and cash flows. 
We invest in new technology and processes to provide higher-margin offerings for our customers while limiting and managing our 
environmental risk. We also depend on digital technologies to process and record financial and operating data, and we rely on sophisticated 
information technology systems and infrastructure to support our business, including process control technology. The failure of our technology 
initiatives and systems to perform as we anticipate or a delay in implementing new technology could adversely affect our business, financial 
condition, results of operations and cash flows. For example, the roll-out of our technology initiatives, including our EnviroSourceTM ash 
beneficiation technology, has been slower than previously anticipated, resulting in lower than expected contribution to operating results. 
Additionally, if competitors implement new technologies before we do, allowing such competitors to provide lower-priced or enhanced 
services of superior quality compared to those we provide, this could have an adverse effect on our financial condition, results of operations and 
cash flows. 
If we are unable to protect the confidentiality of our trade secrets fully, or if competitors are able to replicate our technology or services, 
we may suffer a loss in our competitive advantage or market share. 
Though we do not have patents or patent applications relating to many of our key processes and technology, if we cannot maintain our 
trade secrets' confidentiality, or if our competitors replicate our technology or services, our competitive advantage would be diminished. Further, 
our competitors may develop or employ comparable technologies or processes. 
In addition, third parties, from time to time, may initiate litigation against us by asserting that the conduct of our business infringes, 
misappropriates, or otherwise violates intellectual property rights. If we are sued for infringement and lose, we could be required to pay 
substantial damages and/or be enjoined from using or selling the infringing products or technology. Any legal proceeding concerning intellectual 
property could be protracted and costly regardless of the merits of any claim, is inherently unpredictable, and could have a material adverse 
effect on our financial condition, irrespective of its outcome. 
21

 
 
Additionally, we currently license certain third-party intellectual property in connection with our business, and the loss of any such license 
could adversely impact our financial condition and results of operations. 
We may be unable to make attractive acquisitions, integrate acquired businesses successfully or successfully complete divestitures, and 
any inability to do so may disrupt our business and hinder our growth. 
From time to time, we may consider opportunities to acquire or make investments in other businesses and business lines that could 
enhance our technical capabilities, complement our current services, or expand the breadth of our markets. Any completed acquisition's success 
will depend on our ability to integrate the acquired business into our existing operations effectively. The process of integrating acquired 
businesses or dispositions may involve unforeseen difficulties or liabilities and may require a disproportionate amount of our managerial and 
financial resources. Also, possible future acquisitions may be larger and for purchase prices significantly higher than those paid for earlier 
acquisitions. No assurance can be given that we will be able to identify suitable acquisition opportunities, negotiate acceptable terms, obtain 
financing for acquisitions on acceptable terms, or successfully acquire identified targets. Our failure to achieve consolidation savings, integrate 
the acquired businesses and assets into our existing operations successfully or minimize any unforeseen operational difficulties or liabilities 
could have a material adverse effect on our business, financial condition and results of operations. 
We are vulnerable to significant fluctuations in our liquidity or capital requirements that may vary substantially over time. 
Our operations could require us to utilize large sums of working capital, sometimes on short notice and sometimes without assurance of 
recovery of the expenditures. Environmental liabilities could result in significant cash outflows, including those arising from various customer 
contracts and acquisition agreements that require us to indemnify for certain environmental liabilities, litigation risks, unexpected costs or losses 
resulting from acquisitions, contract initiation or completion delays, political conditions, client payment problems and professional liability claims. 
We may be unable to obtain or maintain sufficient bonding capacity, which could preclude us from bidding on certain projects. 
A significant number of our contracts require performance and payment bonds. Sureties typically issue or continue bonds on a 
project-by-project basis, and they can decline to do so at any time or require the posting of additional collateral as a condition thereto. Our ability 
to obtain performance and payment bonds primarily depends on our capitalization, working capital, past performance, management expertise, 
reputation and certain external factors, including the overall capacity of the surety market. Events that adversely affect the insurance and 
bonding markets generally may result in bonding becoming more difficult or costly to obtain in the future. If we are unable to obtain or renew a 
sufficient level of bonding, or if bonding costs were to increase, we may be precluded from bidding on certain projects or successfully contracting 
with certain customers, which could limit the aggregate dollar amount of contracts that we are able to pursue. In addition, even if we are able to 
successfully renew or obtain performance or payment bonds, we may be required to post letters of credit in connection with such bonds, which 
could negatively affect our liquidity and results of operations. 
Our substantial indebtedness could adversely affect our financial condition and prevent us from fulfilling our obligations. 
Our debt consists primarily of our borrowings under the Company’s 8.50% Senior Notes due 2026 (the “Notes”) and for equipment 
financing through notes payables and capital lease obligations. As of December 31, 2021, the Company had total indebtedness of $199.7 
million, excluding debt issuance costs of $11.4 million. A significant portion of our cash flow is required to pay interest and principal on our 
outstanding indebtedness, and we may be unable to generate sufficient cash flow from operations or have future borrowings available to enable 
us to repay our indebtedness or to fund other liquidity needs. 
Our indebtedness could have significant consequences, including the following: 
•require us to use a significant percentage of our cash flow from operations for debt service and the satisfaction of repayment 
obligations, and not for other purposes; 
•limit our ability to borrow money or issue equity to fund our working capital, capital expenditures, acquisitions and debt service 
requirements; 
•    limit our flexibility in planning for, and reacting to, changes in our business; 
•    place us at a competitive disadvantage if we are more leveraged than our competitors; 
•    limit our ability to deduct our interest expense; 
•    make us more vulnerable to adverse economic and industry conditions; and 
22

 
 
•    limit our ability to exploit business opportunities. 
To the extent that we incur new debt in addition to our current debt levels, the leverage risks described above would increase. 
Our variable rate indebtedness related to borrowings under our Asset-Based Lending Credit Agreement subjects us to interest rate risk, 
and the transition away from the London Interbank Offered Rate (“LIBOR”) could have an adverse impact on us. 
On November 30, 2020, the Federal Reserve announced that LIBOR would be phased out and eventually replaced by June 2023. In the 
same announcement, banks were instructed to stop writing contracts using LIBOR by the end of 2021, and all contracts using LIBOR should 
wrap up by June 30, 2023. We expect that the Secured Overnight Financing Rate (or “SOFR”), published by the Federal Reserve Bank of New 
York will replace U.S. Dollar LIBOR as the principal reference rate for U.S. Dollar-denominated floating rate instruments. However, the manner 
and timing of this shift are currently unknown. SOFR is an overnight rate instead of a term rate, making SOFR an inexact replacement for 
LIBOR. 
Borrowings under our Asset-Based Lending Credit Agreement (the “Credit Agreement”) are at variable rates of interest and expose us to 
interest rate risk. As interest rates increase, our debt service obligations on the variable rate indebtedness will increase even if the amount 
borrowed remains the same, and our results of operations and cash flows, including cash available for servicing our indebtedness, will 
correspondingly decrease. Our Credit Agreement contains LIBOR benchmark replacement provisions and has identified the SOFR as its 
preferred alternative rate for the U.S. LIBOR. However, at this time, there can be no assurance as to whether this alternative benchmark or 
resulting interest rates may be more or less favorable than LIBOR or any other unforeseen impacts of the discontinuation of LIBOR. As a result, 
the proposals or consequences related to this transition could have a material adverse effect on our debt service obligations, financing costs, 
liquidity, financial condition, results of operations or cash flows and could impair our access to the capital markets. 
 
We are subject to cyber security risks and interruptions or failures in our information technology systems. A cyber incident could occur 
and result in information theft, data corruption, operational disruption, and/or financial loss. 
We depend on digital technologies to process and record financial and operating data, and we rely on sophisticated information 
technology systems and infrastructure to support our business, including process control technology. At the same time, cyber incidents, including 
deliberate attacks, have increased. The U.S. government has issued public warnings that indicate that energy assets might be specific targets of 
cyber-security threats. Our technologies, systems, and networks and those of our vendors, suppliers and other business partners may become 
the target of cyber-attacks or information security breaches that could result in the unauthorized release, gathering, monitoring, misuse, loss, or 
destruction of proprietary and other information, or other disruption of business operations. In addition, certain cyber incidents, such as 
surveillance, may remain undetected for an extended period. Despite our considerable expenditures and efforts to secure our systems, our 
systems for protecting against cyber security risks may not be sufficient. As the sophistication of cyber incidents continues to evolve, we will 
likely be required to expend additional resources to continue modifying or enhancing our protective measures or investigate and remediate any 
vulnerability to cyber incidents. Additionally, these systems may be susceptible to outages due to fire, floods, power loss, telecommunications 
failures, usage errors by employees, computer viruses, cyber-attacks, or other security breaches or similar events. The failure of any of our 
information technology systems may cause disruptions in our operations, which could adversely affect our revenue and profitability. 
In the normal course of business, we may be subject to judicial, administrative, or other third-party proceedings that could materially and 
adversely affect our reputation, business, financial condition, results of operations, and liquidity. 
We have in the past been, and may in the future be, named as a defendant in lawsuits, claims, and other legal proceedings during the 
ordinary course of our business. In the future, individuals, citizen groups, trade associations, community groups, or environmental activists may 
bring actions against us in connection with our operations that could interrupt or limit the scope of our business. Many of these proceedings 
could raise difficult and complicated factual and legal issues and are subject to uncertainties and complexities. These proceedings may seek, 
among other things, compensation for alleged personal injury, workers’ compensation, employment discrimination, breach of contract, property 
damage, punitive damages, civil penalties, or other losses, consequential damages, or injunctive or declaratory relief. Also, under our service 
agreements, we generally indemnify our customers for claims related to our conduct and the services we provide thereunder. 
With respect to all such proceedings, we have and will, when warranted in the future, accrue expenses in accordance with accounting 
principles generally accepted in the United States (“GAAP”). If such actions or indemnities are ultimately resolved unfavorably at amounts 
exceeding our accrued expenses or at material amounts, the outcome could materially and 
23

 
 
adversely affect our reputation, business, financial condition, and results of operations. In addition, payments of significant amounts, even if 
reserved, could adversely affect our liquidity position. 
We recognize revenue from construction contracts using the cost-to-cost input method; therefore, variations of actual results from our 
assumptions may reduce our profitability. 
    We recognize revenue from construction contracts using the cost-to-cost input method permitted under GAAP, under which we measure the 
percentage of revenue to be recognized in a given period by the percentage of costs incurred to date on the contract to the total estimated costs 
for the contract. The cost-to-cost input method, therefore, relies on estimates of total expected contract costs. Contract revenue and total cost 
estimates are reviewed and revised on an ongoing basis as the work progresses. Adjustments arising from changes in the estimates of contracts 
revenue or costs are reflected in the fiscal period in which such estimates are revised. Estimates are based on management’s reasonable 
assumptions, judgment and experience but are subject to the risks inherent in estimates, including unanticipated delays or technical 
complications. Variances in actual results from related estimates on a large project or on several smaller projects could be material to our results 
of operations. The full amount of an estimated loss on a contract is recognized in the period such a loss is identified. Such adjustments and 
accrued losses could reduce profitability, which could negatively impact our financial condition and results of operations. 
Our balance sheet includes a significant amount of goodwill and intangible assets which have been subject to impairment. A decline in 
our reporting unit's estimated fair value or trade name intangible asset could result in additional asset impairment charges, which would 
be recorded as a non-cash expense in our consolidated statement of operations. 
Goodwill and our trade name and customer relationship intangible assets must be tested for impairment no less than annually. The fair 
value of the goodwill assigned to our reporting unit could decline if projected revenue or cash flows were to be lower in the future due to the 
timing of new awards or other causes. If the carrying value of intangible assets or goodwill exceeded its fair value, the asset would be written 
down to its fair value, with the impairment loss recognized as a non-cash charge in the consolidated statement of operations. 
As of December 31, 2021, we had approximately $62.2 million of goodwill and $53.5 million of our trade name and customer relationship 
intangibles on our balance sheet, which together represent 34% of our total assets. No impairment charges to our goodwill and intangible assets 
were identified during the year ended December 31, 2021. However, changes in our operations' future outlook could result in impairment 
charges, which could have a material adverse effect on our results of operations and financial condition. 
 
Risks Related to Our Common Stock 
Our stock's market price may be influenced by many factors, some of which are beyond our control. 
These factors include the various risks described in this section as well as the following: 
•the failure of securities analysts to continue to cover our common stock or changes in financial estimates or recommendations by 
analysts; 
•announcements by us or our competitors of significant contracts, acquisitions, or capital commitments; 
•changes in market valuation or earnings of our competitors; 
•variations in quarterly operating results; 
•internal control failures; 
•changes in management; 
•availability of capital; 
•general economic conditions; 
•terrorist acts; 
•natural disasters and pandemics; 
•legislation; 
•future sales of our common stock; and 
•investor perception of us and the power generation industry. 
24

 
 
Additional factors that do not specifically relate to our company or the electric utility industry may also materially reduce our common 
stock market price, regardless of our operating performance. 
The concentration of our capital stock will limit other stockholders’ ability to influence corporate matters. 
Bernhard Capital Partners Management, LP and its affiliates (“BCP”) beneficially own approximately 45% of the total voting power of our 
outstanding shares of common stock and all of the outstanding Series A Preferred Stock (“Preferred Stock”). The Preferred Stock is convertible 
at BCP's option at any time into shares of common stock. As a result, BCP can exert substantial influence or actual control over our 
management and affairs and most matters requiring our stockholders' actions. The interests of BCP may not coincide with the interests of the 
other holders of our common stock. This concentration of ownership may also affect delaying or preventing a change in control otherwise 
favored by our other stockholders, which could depress our common stock's market price. 
BCP and its respective affiliates are not limited in their ability to compete with us, and the corporate opportunity provisions in our 
amended and restated certificate of incorporation could enable BCP to benefit from corporate opportunities that might otherwise be 
available to us. 
Our governing documents provide that BCP and its respective affiliates (including portfolio investments of BCP and its affiliates) are not 
restricted from owning assets or engaging in businesses that compete directly or indirectly with us. In particular, subject to the limitations of 
applicable law, our amended and restated certificate of incorporation, among other things: 
•    permits BCP and its respective affiliates to conduct business that competes with us and to make investments in any kind of property 
in which we may make investments; and 
•    provides that if BCP or its respective affiliates, or any employee, partner, member, manager, officer or director of BCP or its 
respective affiliates, which is also one of our directors or officers, becomes aware of a potential business opportunity, transaction, or 
other matter, they will have no duty to communicate or offer that opportunity to us. 
BCP or its respective affiliates may become aware, from time to time, of certain business opportunities (such as acquisition 
opportunities) and may direct such opportunities to other businesses in which they have invested, in which case we may not become aware of or 
otherwise have the ability to pursue such opportunity. Furthermore, such businesses may choose to compete with us for these opportunities, 
possibly causing these opportunities to not be available to us or causing them to be more expensive for us to pursue. In addition, BCP and its 
respective affiliates may dispose of properties or other assets in the future without any obligation to offer us the opportunity to purchase any of 
those assets. As a result, our business or prospects may be negatively affected if such parties procure attractive business opportunities for their 
benefit rather than for ours. 
We have engaged in transactions with our affiliates, and we may do so in the future. The terms of such transactions and the resolution of 
any conflicts that may arise may not always be in our or our stockholders’ best interests. 
We have engaged in transactions with affiliated companies in the past and may do so in the future. The terms of such transactions and 
the resolution of any conflicts that may arise may not always be as favorable as may be obtained with a third party. 
Our amended and restated certificate of incorporation and amended and restated bylaws, as well as Delaware law, contain provisions 
that could discourage acquisition bids or merger proposals, which may adversely affect the market price of our common stock. 
Our amended and restated certificate of incorporation authorizes our board of directors to issue preferred stock without stockholder 
approval. If our board of directors elects to issue preferred stock, it could be more difficult for a third party to acquire us. Also, some provisions of 
our amended and restated certificate of incorporation and amended and restated bylaws could make it more difficult for a third party to acquire 
control of us, even if the change of control would be beneficial to our stockholders, including: 
•    after BCP and its affiliates no longer collectively hold more than 35% of the voting power of our common stock, providing that all 
vacancies, including newly created directorships, may, except as otherwise required by law or, if applicable, the rights of holders of a 
series of preferred stock, only be filled by the affirmative vote of a majority of directors then in office, even if less than a quorum 
(before such time, vacancies may also be filled by stockholders holding a majority of the outstanding shares entitled to vote); 
•    after BCP and its affiliates no longer collectively hold more than 35% of the voting power of our common stock, permitting any action 
by stockholders to be taken only at an annual meeting or special meeting rather than by written consent of the stockholders, subject 
to the rights of any series of preferred stock concerning such rights; 
 
25

 
 
•    after BCP and its affiliates no longer collectively hold more than 35% of the voting power of our common stock, permitting our 
amended and restated certificate of incorporation and amended and restated bylaws to be amended by the affirmative vote of the 
holders of at least two-thirds of our then outstanding shares of stock entitled to vote thereon; 
•    after BCP and its affiliates no longer collectively hold more than 35% of the voting power of our common stock, permitting special 
meetings of our stockholders to be called only by our board of directors pursuant to a resolution adopted by the affirmative vote of a 
majority of the total number of authorized directors whether or not there exist any vacancies in previously authorized directorships 
(before such time, a special meeting may also be called at the request of stockholders holding a majority of the outstanding shares 
entitled to vote); 
•    after BCP and its affiliates no longer collectively hold more than 35% of the voting power of our common stock, requiring the 
affirmative vote of the holders of at least 75% in voting power of all then outstanding common stock entitled to vote generally in the 
election of directors, voting together as a single class, to remove any or all of the directors from office at any time, and directors will 
be removable only for “cause”;  
•    dividing our board of directors into three classes of directors, with each class serving staggered three-year terms; 
•    prohibiting cumulative voting in the election of directors; 
•    establishing advance notice provisions for stockholder proposals and nominations for elections to the board of directors to be acted 
upon at meetings of stockholders; and 
•    providing that the board of directors is expressly authorized to adopt or alter or repeal our amended and restated bylaws. 
Our amended and restated certificate of incorporation designates the Court of Chancery of the State of Delaware as the sole and 
exclusive forum for certain types of actions and proceedings that our stockholders may initiate, which could limit our stockholders’ ability 
to obtain a favorable judicial forum for disputes with us or our directors, officers, employees, or agents. 
Our amended and restated certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, 
the Court of Chancery of the State of Delaware will, to the fullest extent permitted by applicable law, be the sole and exclusive forum for (i) any 
derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, 
officers, employees, agents, or stockholders to us or our stockholders, (iii) any action asserting a claim against us or any director, officer, 
employee, or agent of ours arising under any provision of the Delaware General Corporation Law (the “DGCL”), our amended and restated 
certificate of incorporation or our amended and restated bylaws, or (iv) any action asserting a claim that is governed by the internal affairs 
doctrine. Any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock will be deemed to have notice of, and 
consented to, the provisions of our amended and restated certificate of incorporation described in the preceding sentence. This choice of forum 
provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers, 
employees, or agents, which may discourage such lawsuits against us and such persons. Alternatively, if a court were to find these provisions of 
our amended and restated certificate of incorporation inapplicable to, or unenforceable in respect of, one or more of the specified types of 
actions or proceedings, we may 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 shares of our common stock. Consequently, your only opportunity to achieve a return on your 
investment is if our common stock price appreciates. 
We do not plan to declare cash dividends on shares of our common stock in the foreseeable future. Additionally, our debt agreements 
place certain restrictions on our ability to pay cash dividends on common stock. Consequently, your only opportunity to achieve a return on your 
investment in us will be if you sell your common stock at a price higher than you paid for it. There is no guarantee that our common stock price 
will prevail in the market will ever exceed the price you paid for it. 
Shares eligible for future sale may cause our common stock's market price to drop significantly, even if our business is doing well. 
Our common stock market price could decline due to sales of a large number of shares of our common stock in the market or the 
perception that these sales could occur. These sales, or the possibility that these sales may occur, also might make it more difficult for us to sell 
equity securities in the future at a time and at a price that we deem appropriate.

On March 16, 2020, we issued $26.0 million in Preferred Stock to BCP, the terms of which could adversely affect the voting power or 
value of our common stock. 
We currently have 26,000 shares of Preferred Stock outstanding, which is convertible at BCP's option at any time following the 
three-month anniversary of the issuance date into shares of common stock with an initial conversion price of $2.77 per share. Dividends will be 
payable quarterly at a rate of 13% per annum, provided that we pay dividends in-kind through the issuance of additional shares to BCP. Our 
Preferred Stock gives BCP a superior right to our assets upon liquidation compared to our common stock and could adversely impact the voting 
power or value of our common stock. For example, our preferred stock provides BCP the right to nominate one member of the Company's board 
of directors and the right to veto specified transactions. Similarly, the repurchase or redemption rights or liquidation preferences assigned to BCP 
could affect the common stock's residual value. 
Taking advantage of the reduced disclosure requirements applicable to “emerging growth companies” may make our common stock less 
attractive to investors. 
We qualify as an “emerging growth company” as defined in the Jumpstart Our Business Startups Act (the “JOBS Act”). An emerging 
growth company may take advantage of certain reduced reporting and other generally applicable public company requirements. Under these 
reduced disclosure requirements, emerging growth companies are not required to, among other things, comply with the auditor attestation 
requirements of Section 404 of the Sarbanes-Oxley Act of 2002, provide certain disclosures regarding executive compensation, hold stockholder 
advisory votes on executive compensation, or obtain stockholder approval of any golden parachute payments not previously approved. In 
addition, emerging growth companies have extended phase-in periods to adopt new or revised financial accounting standards. 
We intend to take advantage of all of the reduced reporting requirements and exemptions, including the extended phase-in periods for 
adopting new or revised financial accounting standards under Section 107 of the JOBS Act, until we are no longer an emerging growth company. 
Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards until those standards apply to private 
companies. If we were to subsequently elect instead to comply with these public company effective dates, such an election would be irrevocable 
under Section 107 of the JOBS Act. 
Our election to use the longer phase-in periods permitted by this election may make it difficult to compare our financial statements to 
those of non-emerging growth companies and other emerging growth companies that have opted out of the extended phase-in periods under 
Section 107 of the JOBS Act and who will comply with new or revised financial accounting standards. We cannot predict if investors will find our 
common stock less attractive because we will rely on these exemptions. If some investors find our common stock less attractive as a result, 
there may be a less active trading market for our common stock, and our common stock price may be more volatile. 
If securities or industry analysts do not publish research or reports about our business, if they adversely change their recommendations 
regarding our common stock, or our operating results do not meet their expectations, our stock price could decline. 
Our common stock's trading market is influenced by the research and reports that industry or securities analysts publish about us or our 
business. If one or more of these analysts cease coverage of our company or fail to publish reports on us regularly, we could lose visibility in the 
financial markets, which in turn could cause our stock price or trading volume to decline. Moreover, if one or more of the analysts who cover our 
company adversely changes their recommendation concerning our common stock or if our operating results do not meet their expectations, our 
stock price could decline. 
We have identified a material weakness in our internal control over financial reporting. If we fail to remediate the material weakness, or if 
we experience additional material weaknesses in the future or otherwise fail to maintain an effective system of internal controls, we may not be 
able to accurately or timely report our financial condition or results of operations, which may adversely affect investor confidence in us and, as a 
result, the value of our common stock. 
Effective internal control over financial reporting is necessary for us to provide reliable financial reports and, together with adequate 
disclosure controls and procedures, is designed to prevent fraud. Any failure to implement required new or improved controls, or difficulties 
encountered in the implementation, could cause us to fail to meet our reporting obligations. In addition, any testing by us, as and when required, 
our independent registered public accounting firm may reveal deficiencies in our internal control over financial reporting that are deemed to be 
material weaknesses or that may require prospective or retroactive changes to our financial statements or identify other areas for further 
attention or improvement. Inferior internal controls could also cause investors to lose confidence in our reported financial information, which 
could have a negative effect on the trading price of our common stock. 
Management identified a material weakness in our internal control over financial reporting in connection with our assessment as of and 
for the year ended December 31, 2021. A material weakness is a deficiency, or combination of 
27

 
 
deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or 
interim financial statements will not be prevented or detected on a timely basis. Specifically, these control deficiencies constitute a material 
weakness, in the aggregate, relating to: (i) the lack of a sufficient number of trained resources with assigned responsibilities and accountability 
for the design and operation of internal controls over financial reporting; (ii) the lack of formal and effective controls over certain financial 
statement account balances, (iii) the lack of user profiles to ensure adequate restriction of users to perform only transactions that are consistent 
with their function; and (iv) the lack of appropriate segregation of duties within the accounting and finance functions, including order to cash, 
process to pay and payroll business processes. 
Although we have begun to implement measures to address the material weakness, the implementation of these measures may not fully 
address the material weakness and deficiencies in our internal control over financial reporting, and we cannot conclude that these matters have 
been fully remedied. As we continue to evaluate, and work to improve, our internal control over financial reporting, management may determine 
that additional or different measures to address control deficiencies or modifications to the remediation plan are necessary. Further, in the future, 
we may determine that we have additional material weaknesses. Our failure to remediate the material weakness or failure to identify and 
address any other material weaknesses or control deficiencies could result in inaccuracies in our financial statements and could also impair our 
ability to comply with applicable financial reporting requirements and related regulatory filings on a timely basis, which could cause investors to 
lose confidence in our reported financial information, which may result in volatility in and a decline in the market price of our common stock. 
 
Item 1B. Unresolved Staff Comments 
None. 
 
Item 2. Properties 
While many of our employees are embedded directly at our customers’ power generation facilities, we lease our corporate headquarters 
in Louisville, Kentucky and own and lease other facilities throughout the United States where we conduct business. Our facilities are utilized for 
operations in our reportable segment and include offices, equipment yards, mines, storage, and manufacturing facilities. As of December 31, 
2021, we owned two of our facilities and leased the remainder. We believe that our existing facilities are sufficient for our current needs. 
 
Item 3. Legal Proceedings 
We are from time-to-time party to various lawsuits, claims and other legal proceedings that arise in the ordinary course of our business. 
With respect to all such lawsuits, claims and proceedings, we record reserves when it is probable a liability has been incurred, and the amount of 
loss can be reasonably estimated. Although it is difficult to predict the ultimate outcome of these lawsuits, claims and proceedings, we do not 
believe that the ultimate disposition of any of these matters, individually or in the aggregate, would have a material adverse effect on our results 
of operations, financial position or cash flows. We maintain liability insurance for certain risks that is subject to certain self-insurance limits. 
 
Item 4. Mine Safety Disclosures 
Not applicable.

PART II 
 
Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities 
Our common stock shares and our Notes trade on the New York Stock Exchange under the symbols “CHRA” and "CHRB," respectively. 
As of March 21, 2022, there were 2,523 stockholders of record of our common stock. We have not paid dividends on our common stock

Charah Solutions, Inc. 
Charah Solutions, Inc. (together with its subsidiaries, “Charah Solutions,” the “Company,” “we,” “us” or “our”) was incorporated in 
Delaware in 2018 in connection with our initial public offering in June 2018 and, together with its predecessors, has been in business since 1987. 
Since our founding, we have continuously worked to anticipate our customers’ evolving environmental needs, increasing the number of services 
we provide through our embedded presence at their power generation facilities. Our multi-service platform allows customers to gain efficiencies 
from sourcing multiple required offerings from a single, trusted partner compared to service providers with a more limited scope. 
 
Overview 
We are a leading national service provider of mission-critical environmental services and byproduct recycling to the power generation 
industry. We offer a suite of remediation and compliance services, byproduct services, raw material sales and Environmental Risk Transfer 
(“ERT”) services. We also design and implement solutions for complex environmental projects (such as coal ash pond closures) and facilitate 
coal ash recycling through byproduct marketing and other beneficial use services. We believe we are a partner of choice for the power 
generation industry due to our quality, safety, domain experience, and compliance record, all of which are key criteria for our customers. In 2021, 
we performed work at more than 40 coal-fired generation sites nationwide. 
On November 19, 2020, the Company sold its Allied Power Holdings LLC (“Allied”) subsidiary engaged in maintenance, modification and 
repair services to the nuclear and fossil power generation industry to an affiliate of Bernhard Capital Partners Management, LP (“BCP”), the 
Company’s majority shareholder, in an all-cash deal for $40 million (the “Allied Transaction”) subject to customary adjustments for working 
capital and other adjustments as set forth in the Purchase Agreement. As described in further detail in Part II, Item 8. Financial Statements and 
Supplementary Data, the company has presented Allied as discontinued operations in the accompanying consolidated financial statements and 
related notes.

We operate as a single operating segment, reflecting the suite of end-to-end services we offer our utility partners and how our chief 
operating decision maker reviews consolidated financial information to evaluate results of operations, assess performance and allocate 
resources for these services. We provide the following services through our one segment: remediation and compliance services, byproduct 
services, raw material sales and ERT services. Remediation and compliance services are associated with our customers’ need for multi-year 
environmental improvement and sustainability initiatives, whether driven by regulatory requirements, power generation customer initiatives or 
consumer expectations and standards. Byproduct services consist of recurring and mission-critical coal ash management and operations for 
coal-fired power generation facilities while also supporting both our power generation customers’ desire to recycle their recurring and legacy 
volumes of coal combustion residuals (“CCRs”), commonly known as coal ash, and our ultimate end customers’ need for high-quality, 
cost-effective supplemental cementitious materials (“SCMs”) that provide a sustainable, environmentally-friendly substitute for Portland cement 
in concrete. Our raw materials sales provide customers with the raw materials that are essential to their business while also providing the 
sourcing, logistics, and management needed to facilitate these raw materials transactions around the globe. ERT services represent an 
innovative solution designed to meet utility customers' evolving and increasingly complex plant closure and environmental remediation needs. 
These customers need to retire and decommission older or underutilized assets while maximizing the asset's value and improving the 
environment. Our ERT services manage the sites' environmental remediation requirements, benefiting the communities and lowering the utility 
customers' costs 
COVID-19 Update 
The pandemic caused by a novel coronavirus (“COVID-19”) has impacted many aspects of our operations, directly and indirectly, 
including our employees, the services we provide at our customers’ power generation facilities, our suppliers and the overall market. We, along 
with our utility partners, have implemented the precautionary health and safety measures recommended by the Centers for Disease Control and 
Prevention (the “CDC”) in response to the COVID-19 pandemic, including, but not limited to: an employee health status questionnaire, taking 
daily temperatures, enhanced sanitation practices and cleaning surfaces throughout each shift, and increasing the number of hand sanitizing 
stations. We have also implemented social distancing measures such as staggering shift start and stop times and break times with additional 
break spaces to support social distancing as well as holding safety meetings outside of the site trailer. Furthermore, we have implemented 
work-from-home measures for the majority of office employees. Understanding that the COVID-19 challenge is evolving, based on new 
information and feedback, we continue to monitor the situation and update our proactive measures in coordination with our customers. We 
continue to work closely with our utility partners and concrete producer customers to meet their needs and monitor any potential slowdowns of 
byproduct recycling and marketing services if there is decreased demand for construction materials. 
The COVID-19 pandemic presents potential new risks to the Company’s business, including logistical, supply chain and other 
challenges that may continue to affect demand for services, which are driven by construction activity, and the timing of our remediation and 
compliance services projects, due to delays in new contract awards and increasing costs and declining availability for certain machinery and 
equipment. 
 
How We Evaluate Our Operations 
We use a variety of financial and operational metrics to assess the performance of our operations, including: 
•Revenue; 
•Gross Profit; 
•Operating Income; 
•Adjusted EBITDA; and 
•Adjusted EBITDA Margin. 
Revenue 
We analyze our revenue by comparing actual revenue to our internal projections for a given period and to prior periods to assess our 
performance. We believe that revenue is a meaningful indicator of the demand and pricing for our services. 
Gross Profit 
We analyze our gross profit, which we define as revenue less cost of sales, to measure our financial performance. We believe gross 
profit is a meaningful metric because it provides insight into our revenue streams' financial performance without consideration of Company 
overhead. When analyzing gross profit, we compare actual gross profit to our internal projections for a given period and prior periods to assess 
our performance. 
 
31

 
 
Operating Income 
We analyze our operating income, which we define as revenue less cost of sales, general and administrative expenses, gain on change 
in contingent payment liability and impairment expense to measure our financial performance. We believe operating income is a meaningful 
metric because it provides insight into profitability and operating performance based on our assets' cost basis. We also compare operating 
income to our internal projections for a given period and to prior periods. 
Adjusted EBITDA and Adjusted EBITDA Margin 
We view Adjusted EBITDA and Adjusted EBITDA Margin, which are non-GAAP financial measures, as important indicators of 
performance because they allow for an effective evaluation of our operating performance compared to our peers, without regard to our financing 
methods or capital structure. 
We define Adjusted EBITDA as net loss attributable to Charah Solutions, Inc. before income from discontinued operations, net of tax, 
interest expense, net, loss on extinguishment of debt, impairment expense, gain on change in contingent payment liability, income taxes, 
depreciation and amortization, equity-based compensation, the Brickhaven contract deemed termination revenue reversal and 
transaction-related expenses and other items. Adjusted EBITDA margin represents the ratio of Adjusted EBITDA to total revenue. See 
“—Non-GAAP Financial Measures” below for more information and a reconciliation of Adjusted EBITDA to net loss, the most directly comparable 
financial measure calculated and presented in accordance with GAAP. 
 
Key Factors Affecting Our Business and Financial Statements 
Ability to Capture New Contracts and Opportunities 
Our ability to grow revenue and earnings is dependent on maintaining and increasing our market share, renewing existing contracts, and 
obtaining additional contracts from proactive bidding on contracts with new and existing customers. We proactively work with existing customers 
ahead of contract end dates to attempt to secure contract renewals. We also leverage the embedded long-term nature of our customer 
relationships to obtain insight and capture new business opportunities across our platform. 
Seasonality of Business 
Based on historical trends, we expect our operating results to vary seasonally. Variations in normal weather patterns can also cause 
changes in energy consumption which may influence the demand and timing of associated services for our byproduct services offerings. Our 
byproduct services and raw material sales are also negatively affected during winter months when the use of cement and cement products is 
generally lower. Inclement weather can impact construction-related activities associated with pond and landfill remediation, which affects the 
timing of revenue generation for our remediation and compliance services. 
Project-Based Nature of Environmental Remediation Mandates 
We believe there is a significant pipeline of coal ash ponds and landfills that will require remediation and/or closure in the future. Due to 
their scale and complexity, these environmental remediation projects are typically completed over longer periods. As a result, our revenue from 
these projects can fluctuate over time. Some of our revenue from projects is recognized over time using the cost-to-cost input method of 
accounting for GAAP purposes, based primarily on contract costs incurred to date compared to total estimated contract costs. This method is the 
most accurate measure of our contract performance because it depicts the company’s performance in transferring control of goods or services 
promised to customers according to a reasonable measure of progress toward complete satisfaction of the performance obligation. The timing of 
revenue recorded for financial reporting purposes may differ from actual billings to customers, sometimes resulting in costs and billing in excess 
of actual revenue. Because of the risks in estimating gross profit margins for long-term jobs, actual results may differ from these estimates. 
Byproduct Recycling Market Dynamics 
There is a growing demand for recycled coal ash across various applications driven by market forces and governmental regulations, 
creating the need to dispose of coal ash in an environmentally sensitive manner. Pricing of byproduct services and raw material sales are driven 
by supply and demand market dynamics as well as the chemical and physical properties of the ash. As demand increases for the end-products 
that use CCRs’ (i.e., concrete for construction and infrastructure projects), the demand for recycled coal ash also typically rises. These 
fluctuations affect the relative demand for our services. In recessionary periods, construction and infrastructure spending and the corresponding 
need for concrete may decline. However, this unfavorable effect may be partially offset by an increase in the demand for recycled coal ash 
during recessionary periods, given that coal ash is more cost-effective than other alternatives. 
 
32

 
 
Power Generation Industry Spend on Environmental Liability Management and Regulatory Requirements 
The power generation industry has increased annual spending on environmental liability management. We believe this results from 
regulatory requirements and consumer pressure, and the industry’s increasing focus on environmental stewardship. Continued increases in 
spending on environmental liability management by our customers should result in increased demand for services across our platform. 
Many power generation entities are experiencing an increased need to retire and decommission older or less economically viable 
generating assets while minimizing costs and maximizing the value of the assets and improving the environment. Our ERT services allow these 
partners to remove the environmental risk and insurance obligations and place control and oversight with a company specializing in these 
complex remediation and reclamation projects. We believe our broad set of service capabilities, track record of quality service and safety, 
exacting environmental standards, and a dependable and experienced labor force is a significant competitive advantage. Our work, mission and 
culture are directly aligned with meeting environmental, sustainability, and governance (“ESG”) standards and providing innovative services to 
solve our utility customers’ most complex environmental challenges. We believe that we are an industry leader in quality, safety, and 
compliance, and we are committed to reducing greenhouse gas emissions and preserving our environment for a cleaner energy future. 
Cost Management and Capital Investment Efficiency 
Our principal operating costs consist of labor, material and equipment costs and equipment maintenance. We focus on cost 
management and efficiency, including monitoring labor costs, both in terms of wage rates and headcount, along with other costs such as 
materials and equipment. We believe we maintain a disciplined approach to capital expenditure decisions, typically associated with specific 
contract requirements. Furthermore, we strive to extend our equipment's useful life by applying a well-planned routine maintenance program. 
How We Generate Revenue 
Our remediation and compliance services primarily consist of designing, constructing, managing, remediating and closing ash ponds and 
landfills on customer-owned sites. 
Our byproduct services include recycling recurring and contracted volumes of coal-fired power generation waste byproducts, such as fly 
ash, bottom ash, IGCC slag and gypsum byproducts, each of which can be used for various industrial purposes. Byproduct services also include 
the management of coal ash which is mission-critical to power plants’ daily operations including silo management, on-site ash transportation and 
capture, and disposal of combustion byproducts from coal-power operations. More than 90% of our services work is time and materials based, 
cost reimbursable or unit price contracts, which significantly reduces the risk of loss on contracts and provides gross margin visibility. Revenue 
from management contracts is recognized when the ash is hauled to the landfill or the management services are provided. Revenue from the 
sale of ash is recognized when it is delivered to the customer. Revenue from construction contracts is recognized using the cost-to-cost input 
method. 
Our raw materials sales provide customers with the raw materials that are essential to their business while also providing the sourcing, 
logistics, and management needed to facilitate these raw materials transactions around the globe. 
Revenue from construction contracts is recognized using the cost-to-cost input method. Revenue from management contracts is 
recognized when the ash is hauled to the landfill or the management services are provided. Revenue from the sale of ash is recognized when it 
is delivered to the customer. This combination of one-stop related services deepens customer connectivity and drives long-term relationships, 
which we believe are critical for renewing existing contracts, winning incremental business from existing customers at new sites and adding new 
customers. 
 
Overview of Financial Results 
In 2021, we won approximately $840 million in contracted new business awards compared to $715 million in 2020 and $430 million in 
2019. The 2021 awards span all of our lines of business and included two ERT projects, two large and several mid-size and smaller remediation 
and compliance projects, several ash marketing agreements, and multiple renewals of existing contracts. Revenue contributions from these new 
awards will be recognized beginning in 2021 and 2022 and, for some awards, continue beyond 2022. We believe that our unique ability to 
provide a single-source solution for large-scale and complex environmental challenges continues to position us well to capture a significant 
portion of a large and growing addressable market, although the timing of future awards is uncertain. We believe that regulatory developments in 
several states as well as at the federal level will positively impact our business opportunities over time as state legislatures and the EPA become 
more prescriptive in their requirements to remediate ash ponds. In addition, customer interest in our ERT services and our EnviroSourceTM ash 
beneficiation technology remains strong. We made significant progress on a major ERT project in 
33

 
 
2021 and announced two additional ERT projects in 2021 and early 2022, with the acquisitions of both expected to close in the second quarter of 
2022. We also have contracts for EnviroSourceTM under discussion with potential utility customers. 
During the year ended December 31, 2021, we completed a significant refinancing, issuing $135.0 million of unsecured senior notes and 
approximately 2.9 million shares of common stock for $13.0 million. Proceeds from the refinancing were used to repay all loans and borrowings 
outstanding under our Credit Facility, which totaled $126.5 million. We terminated the Credit Facility and replaced it with a new asset-based 
lending facility in November 2021, as discussed below in “—Liquidity and Capital Resources—Our Debt Agreements.” These transactions 
improved our financial flexibility, extended our debt maturity profile and reduced our debt service requirements. We believe they enhance our 
ability to grow our business. 
Our primary ongoing sources of liquidity and capital resources are cash on the balance sheet, cash flows generated by operating 
activities and availability under our asset-based lending facility. In part due to longer sales cycles, driven by the increase in the size, scope and 
complexity of remediation and compliance projects that we are bidding on, we have experienced contract initiation delays and project completion 
delays that have adversely affected our revenue and overall liquidity. Our lengthy and complex projects require us to expend large sums of 
working capital, and delays in payment receipts, project commencement or project completion can adversely affect our financial position and the 
cash flows that typically fund our expenditures. See “—Liquidity and Capital Resources-Our Debt Agreements—Existing Credit Facility” below for 
more information about the Credit Facility.

Revenue. Revenue increased $60.8 million, or 26.2%, to $293.2 million for the year ended December 31, 2021, as compared to $232.4 
million for the year ended December 31, 2020, primarily driven by an increase in remediation and compliance services revenue of $79.8 million 
from the commencement of new project work. This increase was partially offset by (i) lower raw materials sales of $13.6 million resulting from 
reduced supply from international sources due to supply chain constraints resulting from significantly higher ocean cargo rates that have led to a 
decrease in profitable imported fly ash sales opportunities and (ii) lower byproduct services revenue of $5.3 million primarily due to the 
dissolution of our Ash Ventures LLC joint venture in the second quarter of 2021. 
Gross Profit. Gross profit increased $3.1 million, or 13.6%, to $25.9 million for the year ended December 31, 2021 as compared to $22.8 
million for the year ended December 31, 2020. As a percentage of revenue, gross profit was 8.8% and 9.8% for the years ended December 31, 
2021 and 2020, respectively. The increase in gross profit was primarily driven by an increase in revenue as discussed above, partially offset by a 
lower gross profit margin percentage. The decline in gross profit margin was primarily driven by issues at certain remediation and compliance 
projects, most of which are nearing completion, resulting from construction delays and supply chain issues, mostly affecting the fourth quarter of 
2021. 
General and Administrative Expenses. General and administrative expenses increased $8.1 million, or 23.9%, to $42.2 million for the 
year ended December 31, 2021, as compared to $34.1 million for the year ended December 31, 2020. The increase was primarily attributable to 
the absence of a $7.1 million reduction in expense from the expiration of our purchase option liability on our structural fill sites. 
Gain on sales-type lease. Gain on sales-type lease increased $5.6 million for the year ended December 31, 2021 due to the recognition 
of a parcel transferred under a sales-type lease at an ERT project as discussed in Note 6, Balance Sheet Items, to the accompanying 
consolidated financial statements. 
Gains on sales of real estate, property and equipment, net. Gains on sales of real estate, property and equipment, net increased $23.5 
million for the year ended December 31, 2021 due to the commencement of operations on the Gibbons Creek ERT project in 2021 that led to 
sales of certain parcels of land acquired and increased scrap sales from the demolition of the power plant, as well as due to the sale of certain 
grinding-related assets. 
 
35

 
 
Gain on ARO settlement. Gain on ARO settlement increased $3.6 million for the year ended December 31, 2021 due to differences 
between the estimated costs used in the measurement of the fair value of the Company's AROs and the actual costs incurred for specific 
remediation tasks recognized on a proportionate basis. 
Other operating expenses from ERT services. Other operating expenses from ERT services increased $5.1 million for the year ended 
December 31, 2021 due to expenses associated with the commencement of operations on the Gibbons Creek ERT project in 2021. 
Gain on Change in Contingent Payment Liability. A gain on the change in contingent payment liability resulted in a $9.7 million benefit for 
the year ended December 31, 2020 and did not recur in 2021. We reduced the associated liability because we determined that certain 
performance sales levels using the grinding technology mentioned below would not be achieved. 
Impairment Expense. Impairment expense decreased $37.2 million to $0.8 million for the year ended December 31, 2021, as compared 
to $38.0 million for the year ended December 31, 2020 primarily driven by (i) the non-recurrence of a $21.0 million impairment of the Charah 
Solutions trade name indefinite-lived intangible asset, (ii) a decrease of $9.8 million of impairments of certain grinding technology equipment and 
construction in progress assets and intangible asset, and (iii) the non-recurrence of a $6.4 million impairment related to our structural fill site 
asset resulting from the expiration of the purchase option liability. 
Interest Expense, Net. Interest expense, net increased $1.5 million, or 10.5%, to $15.2 million for the year ended December 31, 2021, as 
compared to $13.8 million for the year ended December 31, 2020. The increase was primarily attributable to higher debt balances, a higher 
weighted-average cost of capital associated with equipment financing and an increase in amortization of debt issuance costs. 
Loss on Extinguishment of Debt. Loss on extinguishment of debt decreased $8.0 million during the year ended December 31, 2020 due 
to the absence of the Company’s Amendment No. 3 to Credit Agreement (the “Third Amendment”) of our previous Credit Facility. The Company 
expensed $5.2 million in amendment fees and wrote off $3.4 million in previously capitalized debt issuance costs during the year ended 
December 31, 2020. 
Income (Loss) from Equity Method Investment. Income (loss) from equity method investment increased $2.7 million to $0.2 million for 
the year ended December 31, 2021, as compared to a loss from equity investment of $2.5 million for the year ended December 31, 2020. The 
increase period-over-period was primarily attributable to the absence of a $3.8 million impairment of our investment in the joint venture that 
resulted from the fair value of our investment being less than its carrying value at December 31, 2020, partially offset by a decrease in operating 
income from our equity method investment due to the joint venture arrangement ending during the year ended December 31, 2021. 
Income Tax (Expense) Benefit. Income tax (expense) benefit decreased by $1.6 million to a $0.7 million expense for the year ended 
December 31, 2021, as compared to a $0.9 million benefit during the year ended December 31, 2020. The change in balance was primarily 
driven by an increase in the valuation allowance recorded during the year ended December 31, 2021 as compared to the year ended December 
31, 2020 as we were not able to conclude it was more likely than not certain deferred tax assets will be realized. Furthermore, during the year 
ended December 31, 2021 the income tax expense was attributed to the impact of accelerated tax depreciation and amortization of tax goodwill 
on the valuation allowance. 
Income from Discontinued Operations, Net of Tax. Income from discontinued operations, net of tax, decreased $2.7 million for the year 
ended December 31, 2021 due to the sale of our subsidiary through the Allied Transaction during the year ended December 31, 2020. 
Net Loss. Net loss decreased $48.9 million, or 89.4%, to $5.8 million for the year ended December 31, 2021, as compared to $54.7 
million for the year ended December 31, 2020.

Assets 
Total assets increased $63.1 million, driven primarily by: 
ƒ$37.7 million in property and equipment additions, net of disposals, resulting from the Gibbons Creek Transaction and new capital 
leases entered into during the year ended December 31, 2021; 
ƒ$30.0 million in cash and restricted cash due to $10.2 million in cash used in operating activities, $56.4 million in cash provided by 
investing activities and $16.3 million in cash used in financing activities; 
ƒ$8.5 million in increases to contract assets resulting from the commencement of new remediation and compliance services project work 
that has led to additional costs and estimated earnings in excess of billings and retainage; 
ƒ$6.0 million in increases to other assets resulting from a lease receivable recognized during the year ended December 31, 2021 from 
the sales-type lease discussed in Note 6, Balance Sheet Items, to the accompanying consolidated financial statements; and 
ƒ$2.7 million in increases to trade accounts receivable, net from the commencement of new remediation and compliance services and 
the timing of receipts of outstanding payments from customers. 
These increases were partially offset by: 
ƒ$16.7 million in property and equipment depreciation expense during the year ended December 31, 2021; and 
ƒ$7.9 million in intangible asset amortization expense during the year ended December 31, 2021. 
Liabilities 
    Total liabilities increased $54.6 million, primarily driven by: 
•$156.3 million in proceeds from long-term debt; 
•$37.3 million in increases to current and non-current asset retirement obligations (“AROs”) resulting from the AROs acquired in Gibbons 
Creek Transaction and partially offset by ARO liabilities settled and gain on ARO settlement during the year ended December 31, 
2021; 
•$24.5 million in new capital lease obligations entered into during the year ended December 31, 2021; and 
•$17.0 million in increases to accounts payables and accrued expenses from the commencement of new remediation and compliance 
services and the timing of payments to vendors. 
These increases were partially offset by: 
•$154.8 million in principal payments of long-term debt; 
•$13.4 million in new debt issuance costs from our Notes offering and asset-based lending credit agreement; 
•$12.0 million in net payments on our line of credit under our previous Credit Facility; 
•$7.4 million in payments of the working capital adjustment and other items for the Allied Transaction; and 
•$4.8 million in principal payments on capital lease obligations. 
Mezzanine Equity 
Total mezzanine equity increased $8.1 million primarily driven by paid-in-kind dividends and accretion associated with our Preferred 
Stock. 
Total Equity 
Total equity increased $0.5 million, driven primarily by $13.0 million from the issuance of common stock and $2.7 million in share-based 
compensation, partially offset by $8.7 million in paid in-kind and deemed dividends associated with our Preferred Stock, a $5.8 million net loss 
and $0.5 million in taxes paid related to the net settlement of shares. 
Liquidity and Capital Resources 
Our primary ongoing sources of liquidity and capital resources are cash on the balance sheet, cash flows generated by operating 
activities, borrowings under the Notes, proceeds from the issuance of common stock and availability under our asset-based lending credit 
agreement. Due to longer sales cycles, driven by the increase in the size, scope and complexity of remediation and compliance projects that we 
are bidding on, we have experienced contract initiation delays and project completion delays that have adversely affected our revenue and 
overall liquidity. Our long and complex projects require us to 
 
37

 
 
expend large sums of working capital, and delays in payment receipts, project commencement or project completion can adversely affect our 
financial position and the cash flows that typically fund our expenditures. 
As of December 31, 2021, we had cash of $24.3 million and borrowing capacity under our Asset Based Lending Credit Agreement of 
$13.2 million, for total liquidity of $37.5 million. We believe our cash on hand and cash generated from operations will be sufficient to cover our 
working capital requirements and debt obligations for the next 12 months.

Year Ended December 31, 2021 Compared to Year Ended December 31, 2020 
Operating Activities 
Net cash and restricted cash (used in) provided by operating activities decreased $22.7 million to $10.2 million of net cash used in 
operating activities for the year ended December 31, 2021 as compared to $12.5 million of net cash provided by operating activities. The change 
in cash flows provided by operating activities was primarily attributable to: 
ƒa decrease in net loss of $48.9 million. 
ƒa decrease in non-working capital adjustments to net loss of $71.3 million, primarily due to a decrease of $39.9 million in impairment 
expense, an increase of $24.1 million in (gain) loss on sale of property and equipment, a decrease of $8.0 million in loss on 
extinguishment of debt, $5.6 million in gain on a sales-type lease, $3.6 million in gain on ARO settlements, an increase of $2.7 
million in (income) loss from equity method investment and a decrease of $1.6 million in paid-in-kind interest on long-term debt. 
These changes were partially offset by the absence of $9.7 million in gain on change in contingent payment liability and an increase 
of $4.7 million in depreciation and amortization during the year ended December 31, 2021. 
ƒa decrease of $0.3 million from all other operating activities. 
Investing Activities 
Net cash and restricted cash provided by investing activities increased $14.4 million to $56.4 million for the year ended December 31, 
2021, as compared to $42.1 million for the year ended December 31, 2020. The change in cash flows provided by investing activities was 
primarily attributable to a $37.2 increase in proceeds from the sales of real estate, property and equipment, primarily from real estate and scrap 
sales associated with the Gibbons Creek Transaction, $34.9 million in cash and restricted cash received from the Gibbons Creek Transaction, 
and $1.0 million of distributions received from our equity method investment. These increases were partially offset by the absence of $34.9 
million of proceeds from the sale of a subsidiary, net of subsidiary cash, $7.0 million in proceeds received from a sales-leaseback transaction, 
payments of $7.4 million of the working capital adjustment and other items resulting from the Allied Transaction and an increase in capital and 
land improvement expenditures of $4.2 million. 
Financing Activities 
Net cash and restricted cash used in financing activities decreased $15.2 million for the year ended December 31, 2021, to $16.3 million 
as compared to $31.5 million for the year ended December 31, 2020. The change in cash flows used in financing activities was primarily 
attributable to a $156.3 million increase in proceeds received from long-term debt, $13.0 million of proceeds received from the issuance of 
common stock and a decrease of $1.4 million in distributions to our non-controlling interest. These changes were partially offset by an $159.5 
million increase in principal payments on long-term debt and capital lease obligations, the absence of $24.3 million of proceeds received from 
Preferred Stock issuance, an $11.8 million increase in payments of debt issuance costs and the change in net activity of $5.0 million on the line 
of credit. 
Working Capital 
Our working capital, which we define as total current assets less total current liabilities, totaled $31.5 million at December 31, 2021 as 
compared to $21.5 million as of December 31, 2020. This increase in net working capital for the year ended December 31, 2021 was primarily 
due to: 
38

 
 
•increases in restricted cash associated with the Gibbons Creek Transaction and the cash collateral deposits for our letters of credit; 
•increases in contract assets and trade accounts receivable primarily due to an increase in the number of remediation and compliance 
projects and changes in the timing of the related billings and collections associated with these projects; and 
•decreases in current maturities of capital lease obligations and notes payable due to the refinance of our previous Credit Facility into the 
Notes and our use of the proceeds from the Notes, along with cash from the sale of equity to B. Riley, to fully repay and terminate 
the Credit Facility as it became due and payable. 
These changes were partially offset by: 
•increases in the current portion of our asset retirement obligations primarily driven by the AROs acquired in the Gibbon Creek 
Transaction and the estimated timing of such remediation activities; and 
•increases in accounts payable and accrued liabilities, primarily driven by an increase in the number of remediation and compliance 
projects and changes in the timing of the related payments to vendors associated with these projects. 
Our Debt Agreements 
Senior Notes 
On August 25, 2021, the Company completed an offering of $135.0 million, in the aggregate, of the Company’s Notes, which amount 
includes the exercise by the underwriters of their option to purchase an additional $5.0 million aggregate principal amount of Notes. 
The Notes were sold pursuant to the Company’s Registration Statement on Form S-1, as amended (File No. 333-258650), which was 
declared effective by the Securities and Exchange Commission on August 20, 2021. The Notes were issued pursuant to the First Supplemental 
Indenture (the “First Supplemental Indenture”), dated as of August 25, 2021, between the Company and Wilmington Savings Fund Society, FSB, 
as trustee (the “Trustee”). The First Supplemental Indenture supplements the Indenture entered into by and between the Company and the 
Trustee, dated as of August 25, 2021 (the “Base Indenture” and, together with the First Supplemental Indenture, the “Indenture”). 
The public offering price of the Notes was 100.0% of the principal amount. The Company received proceeds before payment of 
expenses and other fees of $135.0 million. The Company used the proceeds, along with cash from the issuance of $13.0 million of common 
stock, to fully repay and terminate the Company’s Credit Facility, as defined below. 
The Notes bear interest at the rate of 8.50% per annum. Interest on the Notes is payable quarterly in arrears on January 31, April 30, 
July 31 and October 31 of each year, commencing October 31, 2021. The Notes will mature on August 31, 2026. 
The Company may redeem the Notes for cash in whole or in part at any time (i) on or after August 31, 2023 and prior to August 31, 
2024, at a price equal to 103% of their principal amount, plus accrued and unpaid interest to, but excluding, the date of redemption, (ii) on or 
after August 31, 2024 and prior to August 31, 2025, at a price equal to 102% of their principal amount, plus accrued and unpaid interest to, but 
excluding, the date of redemption, and (iii) on or after August 31, 2025 and prior to maturity, at a price equal to 100% of their principal amount, 
plus accrued and unpaid interest to, but excluding, the date of redemption. On and after any redemption date, interest will cease to accrue on the 
redeemed Notes. If the Company is redeeming less than all of the Notes, the Trustee will select the Notes to be redeemed by such method as 
the Trustee deems fair and appropriate in accordance with methods generally used at the time of selection by fiduciaries in similar 
circumstances. 
The Indenture also contains customary event of default and cure provisions. If an uncured default occurs and is continuing, the Trustee 
or the holders of not less than 25% in aggregate principal amount of the Notes may declare the Notes to be immediately due and payable. 
The Notes are senior unsecured obligations of the Company and rank equal in right of payment with the Company’s existing and future 
senior unsecured indebtedness. 
As a result of the issuance of the Notes, $12,116 of third-party fees were capitalized as debt issuance costs that will be amortized 
through interest expense, net in the accompanying consolidated statements of operations using the effective interest method through the 
maturity date of the Notes. 
Asset-Based Lending Credit Agreement 
On November 9, 2021, the Company entered into a new Credit Agreement with JPMorgan Chase Bank, N.A. (“JPMorgan”), as 
administrative agent, the lenders party thereto and certain subsidiary guarantors named therein. The Credit 
39

 
 
Agreement provides for a four-year senior secured revolving credit facility with initial aggregate commitments from the lenders of $30.0 million, 
which includes $5.0 million available for swingline loans, plus an additional $5.0 million of capacity available for the issuance of letters of credit if 
supported by cash collateral provided by the Company (with a right to increase such amount by up to an additional $5.0 million) (“Aggregate 
Revolving Commitments”). Availability under the Credit Agreement is subject to a borrowing base calculated based on the value of certain 
eligible accounts receivable, inventory, and equipment of the Company and subject to redeterminations made in good faith and in the exercise of 
permitted discretion of JPMorgan. Proceeds of the Credit Agreements may be used for working capital and general corporate purposes. 
The Credit Agreement provides for borrowings of either base rate loans or Eurodollar loans. Principal amounts borrowed are payable on 
the maturity date with such borrowings bearing interest that is payable (i) with respect to base rate loans, monthly and (ii) with respect to 
Eurodollar loans, the last day of each Interest Period (as defined below); provided that if any Interest Period for a Eurodollar loan exceeds three 
months, interest will be payable on the respective dates that fall every three months after the beginning of such Interest Period. Eurodollar Loans 
bear interest at a rate per annum equal to the Adjusted LIBOR for one, three or six months (the “Interest Period”), plus an applicable margin of 
2.25%. Base rate loans bear interest at a rate per annum equal to the greatest of (i) the agent bank’s reference rate, (ii) the federal funds 
effective rate plus 50 basis points and (iii) the rate for one month Adjusted LIBOR loans plus 100 basis points, plus an applicable rate of 125 
basis points. The Credit Agreement contains a provision for sustainability adjustments annually that will impact the applicable margin by between 
positive 0.05% and negative 0.05% based on the achievement, or lack thereof, of certain metrics agreed upon between JPMorgan and the 
Company and publicly reported through the Company’s annual non-financial sustainability report. 
The Credit Agreement is guaranteed by certain of the Company’s subsidiaries and is secured by substantially all of the Company’s and 
such subsidiaries’ assets. The Credit Agreement contains customary restrictive covenants for asset-based loans that may limit the Company’s 
ability to, among other things: incur additional indebtedness, sell assets, make loans to others, make investments, pay cash dividends to 
common stockholders, limit or restrict payments of cash dividends on preferred equity, enter into mergers, make certain restricted payments, 
incur liens, and engage in certain other transactions without the prior consent of the lenders. 
A covenant testing period (“Covenant Testing Period”) is a period in which excess availability (which is defined in the Credit Agreement 
as the sum of availability and an amount up to $1.0 million) is less than the greater of (a) 12.5% of the lesser of the aggregate revolving 
commitments and the borrowing base, (b) the lesser of $7.5 million and the PP&E Component as defined in the Credit Agreement, and (c) 
$3.5 million, for three consecutive business days. During a Covenant Testing Period, the Credit Agreement requires the Company to maintain a 
fixed charge coverage ratio as defined in the Credit Agreement, determined for any period of twelve (12) consecutive months ending on the last 
day of each fiscal quarter, of at least 1.00 to 1.00. 
As of December 31, 2021, the Company has not drawn on the Credit Agreement. Outstanding letters of credit under this Credit 
Agreement were $19,027 as of December 31, 2021. As of December 31, 2021, the Company had $13.4 million of outstanding letters of credit 
with JPMorgan and $5.6 million with Bank of America, N.A. 
As a result of entering into the Credit Agreement, $1,366 of third-party fees were capitalized as debt issuance costs that will be 
amortized through interest expense, net in the accompanying consolidated statements of operations using the effective interest method through 
the maturity date of the Credit Agreement. 
Letter of Credit Cash Collateralization Promissory Note 
On August 25, 2021, Charah, LLC issued a Secured Promissory Note (the “Promissory Note”), as the borrower, in favor of B. Riley 
Commercial Capital, LLC, as the noteholder (the “Noteholder”), evidencing a loan in aggregate principal amount of $17.9 million made by the 
Noteholder to Charah, LLC. The loan outstanding under the Promissory Note bore interest at a rate of eight percent (8%) per annum and was 
set to mature on the thirteen-month anniversary of the effective date of the Promissory Note. The proceeds of the Promissory Note were used by 
the Company and its subsidiaries to collateralize the Company's existing letters of credit issued through Bank of America, N.A. The loan was 
repaid in full during the year ended December 31, 2021. 
Previous Credit Facility 
On September 21, 2018, we entered into a credit agreement (the “Credit Facility”) by and among us, the lenders party thereto from time 
to time and Bank of America, N.A., as administrative agent (the “Administrative Agent”). The Credit Facility included: 
•A revolving loan not to exceed $50.0 million (the “Revolving Loan”); 
•A term loan of $205.0 million (the “Closing Date Term Loan”); and 
40

 
 
•A commitment to loan up to a further $25.0 million in term loans, which expired in March 2020 (the “Delayed Draw Commitment” and 
the term loans funded under such Delayed Draw Commitment, the “Delayed Draw Term Loan,” together with the Closing Date Term 
Loan, the “Term Loan”). 
Pursuant to the terms of the Credit Facility and its related amendments, all amounts associated with the Revolving Loan and the Term 
Loan under the Credit Facility were set to mature in July 2022. The interest rates per annum applicable to the loans under the Credit Facility 
were based on a fluctuating rate of interest measured by reference to, at our election, either (i) the Eurodollar rate, currently LIBOR, or (ii) an 
alternative base rate. Various margins were added to the interest rate based on our consolidated net leverage ratio (as defined in the Credit 
Facility). Customary fees were payable regarding the Credit Facility and included (i) commitment fees for the unused portions of the Credit 
Facility and (ii) fees on outstanding letters of credit. Amounts borrowed under the Credit Facility were secured by substantially all of the assets of 
the Company. 
The Credit Facility contained various customary representations, warranties, restrictive covenants, certain affirmative covenants, 
including reporting requirements, and customary events of default. 
Outstanding letters of credit under the previous Credit Facility were $11.1 million as of December 31, 2020. 
During the year ended December 31, 2021, using the proceeds from the Notes, along with cash from the sale of equity to B. Riley, to 
fully repay and terminate the Credit Facility, the Company paid $114.1 million of outstanding principal on the Closing Date Loan and 
$12.3 million of outstanding loans on the Revolver. Further, the Company paid $2.0 million of previously accrued fees required as consideration 
for Amendment No. 3 to Credit Agreement that was otherwise due and payable on the maturity date. During the year ended December 31, 2021, 
the Company wrote off unamortized debt issuance costs of $0.6 million as a result of this refinancing, which is included in loss on extinguishment 
of debt in the accompanying consolidated statements of operations. 
Equipment Financing Facilities and Capital Lease Equipment Financing 
We have entered into various equipment financing arrangements to finance the acquisition of certain equipment (the “Equipment 
Financing Facilities”). As of December 31, 2021, we had $17.2 million of equipment notes outstanding. Each of the Equipment Financing 
Facilities includes non-financial covenants, and, as of December 31, 2021, we complied with all such covenants. 
We have entered into various equipment capital lease financing arrangements to finance the acquisition of certain equipment. As of 
December 31, 2021, we had $30.4 million of future minimum lease payments related to this equipment. 
Series A Preferred Stock 
As a condition to the Third Amendment, the Company entered into an agreement with an investment fund affiliated with Bernhard 
Capital Partners Management, LP (“BCP”) to sell 26,000 shares of Series A Preferred Stock, par value $0.01 per share (the “Preferred Stock”), 
for net proceeds of approximately $25.2 million in a private placement (the “Preferred Stock Offering”). The Preferred Stock has an initial 
liquidation preference of $1,000 per share and pays a dividend at the rate of 10% per annum in cash, or 13% if the Company elects to pay 
dividends in-kind by adding such amount to the liquidation preference. Upon meeting certain “specified payment conditions,” the Company has 
the ability under the Asset-Based Lending Credit Agreement to pay cash dividends on the Series A Preferred Stock. However, the Company 
intends to pay dividends-in-kind for the foreseeable future. We used proceeds from the Preferred Stock Offering for liquidity and general 
corporate purposes. 
For more information related to the Series A Preferred Stock, see Note 12 “Mezzanine Equity" to the notes to consolidated financial 
statements included in Part II, Item 8. Financial Statements and Supplementary Data of this Annual Report on Form 10-K. 
Common Stock Issuances 
In August 2021, the Company executed a stock purchase agreement with a previously unrelated third party, B. Riley, and issued 2.9 
million shares of common stock at $4.50 per share in a private placement for total proceeds of $13.0 million. Pursuant to the terms of the stock 
purchase agreement, B. Riley entered into an Investor Rights Agreement and appointed one director to the Company's board of directors.

Non-GAAP Financial Measures 
Adjusted EBITDA 
Adjusted EBITDA and Adjusted EBITDA margin are not financial measures determined in accordance with GAAP. 
We define Adjusted EBITDA as net loss attributable to Charah Solutions, Inc. before income from discontinued operations, net of tax, 
interest expense, net, loss on extinguishment of debt, impairment expense, gain on change in contingent payment liability, income taxes, 
depreciation and amortization, equity-based compensation, the Brickhaven contract deemed termination revenue reversal and 
transaction-related expenses and other items. Adjusted EBITDA margin represents the ratio of Adjusted EBITDA to total revenue. 
We believe Adjusted EBITDA and Adjusted EBITDA margin are useful performance measures because they allow for an effective 
evaluation of our operating performance compared to our peers, without regard to our financing methods or capital structure. We exclude the 
items listed above from net loss attributable to Charah Solutions, Inc. in arriving at Adjusted EBITDA because these amounts are either 
non-recurring or can vary substantially within our industry depending upon accounting methods and book values of assets, capital structures and 
the method by which the assets were acquired. Adjusted EBITDA should not be considered as an alternative to, or more meaningful than, net 
loss attributable to Charah Solutions, Inc. determined according to GAAP. Certain items excluded from Adjusted EBITDA are significant 
components in understanding and assessing a company’s financial performance, such as a company’s cost of capital and tax structure, as well 
as the historic costs of depreciable assets, none of which are reflected in Adjusted EBITDA. Our Adjusted EBITDA presentation should not be 
construed as an indication that our results will be unaffected by the items excluded from Adjusted EBITDA. Our computations of Adjusted 
EBITDA may not be identical to other similarly titled measures of other companies. We use Adjusted EBITDA margin to measure our business's 
success in managing our cost base and improving profitability. The following table presents a reconciliation of Adjusted EBITDA to net loss 
attributable to Charah Solutions Inc., our most directly comparable financial measure calculated and presented in accordance with GAAP, along 
with our Adjusted EBITDA margin.

Critical Accounting Policies and Estimates 
Our financial statements are prepared in accordance with GAAP. In connection with preparing our financial statements, we are required 
to make assumptions and estimates about future events and apply judgments that affect the reported amounts of assets, liabilities, revenue, 
expense, and related disclosures. We base our assumptions, estimates, and judgments on historical experience, current trends and other factors 
that management believes to be relevant when preparing our consolidated financial statements. Regularly, management reviews the accounting 
policies, assumptions, estimates, and judgments to ensure that our consolidated financial statements are presented fairly and in accordance with 
GAAP. However, because future events and their effects cannot be determined with certainty, actual results could differ materially from our 
assumptions and estimates. 
Our significant accounting policies are described in Note 2 to our consolidated financial statements included herein. Our critical 
accounting policies are described below to provide a better understanding of our estimates and assumptions about future events that affect the 
amounts reported in the consolidated financial statements and accompanying notes. Significant accounting estimates are important to the 
representation of our financial position and results of operations and involve our most difficult, subjective or complex judgments. We base our 
estimates on historical experience and various other assumptions we believe to be reasonable according to the current facts and circumstances 
through the date of the issuance of our financial statements. 
Revenue 
To determine revenue recognition for contracts, we evaluate whether two or more contracts should be combined and accounted for as 
one single contract and whether the combined or single contract should be accounted for as more than one performance obligation. This 
evaluation requires significant judgment, and the decision to combine a group of contracts or separate a combined or single contract into multiple 
performance obligations could change the amount of revenue and profit recorded in a given period. Contracts are considered to have a single 
performance obligation if the promise to transfer the individual goods or services is not separately identifiable from other promises in the 
contracts primarily because we provide a service that involves multiple inter-related and integrated tasks to achieve the completion of a specific, 
single project. We allocate the transaction price to each performance obligation for contracts with multiple performance obligations using our 
best estimate of the stand-alone selling price of each distinct good or service in the contract. 
43

 
 
For sales and service contracts where we have the right to consideration from the customer in an amount that corresponds directly with 
the value received by the customer based on our performance to date, revenue is recognized at a point in time when services are performed and 
contractually billable. Certain service contracts contain provisions dictating fluctuating rates per unit for the certain services in which the rates are 
not directly related to changes in the Company’s effort to perform under the contract. We recognize revenue based on the stand-alone selling 
price per unit for such contracts, calculated as the average rate per unit over the term of those contractual rates. This creates a contract asset or 
liability for the difference between the revenue recognized and the amount billed to the customer. 
Under the typical payment terms of our services contracts, amounts are billed as work progresses in accordance with agreed-upon 
contractual terms, at periodic intervals (e.g., weekly, biweekly or monthly). 
We recognize revenue over time, as performance obligations are satisfied, for substantially all of our construction contracts due to the 
continuous transfer of control to the customer. For most of our construction contracts, the customer contracts with us to provide a service that 
involves multiple inter-related and integrated tasks to complete a specific, single project and is therefore accounted for as a single performance 
obligation. We recognize revenue using the cost-to-cost input method, based primarily on contract costs incurred to date compared to total 
estimated contract costs. This method is the most accurate measure of our contract performance because it depicts the company’s performance 
in transferring control of goods or services promised to customers according to a reasonable measure of progress toward complete satisfaction 
of the performance obligation. 
Contract costs include all direct material, labor and subcontractor costs and indirect costs related to contract performance. The costs 
incurred that do not relate directly to transferring a service to the customer are excluded from the input method used to recognize revenue. 
Project mobilization costs are generally charged to the project as incurred when they are an integrated part of the performance obligation being 
transferred to the client. Pre-contract costs are expensed as incurred unless they are expected to be recovered from the client. 
It is common for our contracts to contain contract provisions that give rise to variable consideration such as unpriced change orders or 
volume discounts that may either increase or decrease the transaction price. We estimate the amount of variable consideration at the expected 
value or most likely amount, depending on which is determined to be more predictive of the amount to which the Company will be entitled. 
Variable consideration is included in the transaction price when it is probable that a significant reversal of cumulative revenue recognized will not 
occur or when the uncertainty associated with the variable consideration is resolved. Our estimates of variable consideration and determination 
of whether to include such amounts in the transaction price are based largely on our assessment of legal enforceability, anticipated performance, 
industry business practices, and any other information (historical, current or forecasted) that is reasonably available to us. Variable consideration 
associated with unapproved change orders is included in the transaction price only to the extent of costs incurred. 
We provide limited warranties to customers for work performed under our contracts. Such warranties are not sold separately, assure that 
the services comply with the agreed-upon specifications and legal requirements and do not provide customers with a service in addition to 
assurance of compliance with agreed-upon specifications. Accordingly, these types of warranties are not considered to be separate performance 
obligations. Historically, warranty claims have not resulted in material costs incurred by the Company. 
Due to the nature of the work required to be performed on many of our performance obligations, the estimation of total revenue and cost 
at completion is complex, subject to many variables and requires significant judgment. As a significant change in one or more of these estimates 
could affect the profitability of our contracts, we routinely review and update our contract-related estimates through a disciplined project review 
process in which management reviews the progress and execution of our performance obligations and the estimated costs at completion. As 
part of this process, management reviews information including, but not limited to, outstanding contract matters, progress towards completion, 
program schedule and the associated changes in estimates of revenue and costs. Management must make assumptions and estimates 
regarding the availability and productivity of labor, the complexity of the work to be performed, the availability and cost of materials, the 
performance of subcontractors, and the availability and timing of funding from the customer, along with other risks inherent in performing 
services under all contracts where we recognize revenue over-time using the cost-to-cost method. 
We recognize changes in contract estimates on a cumulative catch-up basis in the period in which the changes are identified. Such 
changes in contract estimates can result in recognition of revenue in a current period for performance obligations that were satisfied or partially 
satisfied in prior periods. Changes in contract estimates may also result in the reversal of previously recognized revenue if the current estimate 
differs from the previous estimate. If at any time the estimate of contract profitability indicates an anticipated loss on the contract, we recognize 
the total loss in the period it is identified. 
Contracts are often modified to account for changes in contract specifications and requirements. Most of our contract modifications are 
for goods or services that are not distinct from existing contracts due to the significant integration provided in 
44

 
 
the context of the contract and are accounted for as if they were part of the original contract. The effect of a contract modification on the 
transaction price and our measure of progress for the performance obligation to which it relates is recognized as an adjustment to revenue 
(either as an increase in or a reduction of revenue) on a cumulative catch-up basis. We account for contract modifications when the modification 
results in the promise to deliver additional goods or services that are distinct and the increase in the price of the contract is for the same amount 
as the stand-alone selling price of the additional goods or services included in the modification. 
Goodwill 
Goodwill represents the cost of an acquisition purchase price over the fair value of acquired net assets, and such amounts are reported 
separately as goodwill on our Consolidated Balance Sheets. Our total goodwill resulted from applying “push-down” accounting associated with 
BCP’s January 2017 acquisition of a controlling equity position in Charah Management and the acquisition of certain assets and liabilities of 
SCB. 
Goodwill is not amortized, but instead is tested for impairment at least annually, at October 1st of each year, or more often if events or 
circumstances indicate that goodwill might be impaired. We test goodwill of the Company as a whole since we concluded the Company was a 
single reporting unit. We may elect to perform a qualitative assessment of our reporting units to determine whether it is more likely than not that 
the reporting units' fair value is greater than their carrying value. If a qualitative assessment is not performed, or if as a result of a qualitative 
assessment it is not more likely than not that the fair value of a reporting unit exceeds its carrying value, then the reporting unit’s fair value is 
compared to its carrying value. We performed a quantitative assessment of the Company using a market approach whereby the market 
capitalization of the Company was compared to its carrying value. The market capitalization was derived from the Company's publicly traded 
stock price. 
Indefinite-Lived Intangible Assets 
We assess our trade name indefinite-lived intangible asset at least annually as of October 1 for impairment, or more frequently if certain 
events occur or circumstances change that would more likely than not reduce the fair value of an indefinite-lived intangible asset below its 
carrying value. The Charah Solutions trade name fair value is based upon the income approach, primarily utilizing the relief from royalty 
methodology. This methodology assumes that a third party would be willing to pay a royalty to obtain the rights to use the comparable asset in 
place of ownership. An impairment loss is recognized when the intangible asset's estimated fair value is less than the carrying value. Fair value 
calculation requires significant judgments in determining both the assets’ estimated cash flows and the appropriate discount and royalty rates 
applied to those cash flows to determine fair value. Variations in economic conditions or a change in general consumer demands, operating 
results estimates or the application of alternative assumptions could produce significantly different results. 
During the year ended December 31, 2021, we performed a quantitative assessment of our trade name indefinite-lived intangible asset 
and determined there was no impairment. For the period between the impairment testing date and year-end, there were no indicators of 
impairment. If actual future results are not consistent with our assumptions and estimates, we may be required to record impairment charges in 
the future. During the year ended December 31, 2020, we recorded an impairment of our Charah Solutions trade name intangible asset of $21.0 
million. As part of the October 1, 2020 annual impairment test, we identified a decrease in the royalty rate used in the valuation primarily 
attributable to the Company's recent performance. 
Some of the inherent estimates and assumptions used in determining the fair value of the indefinite-lived intangible asset are outside 
management control, including interest rates, cost of capital, tax rates and credit ratings. As for the indefinite-lived intangible asset, the most 
significant assumptions used are the revenue growth rate, the royalty rate, and the discount rate. A decrease in the revenue growth rate, a 
decrease in the royalty rate, or an increase in the discount rate could result in a future impairment. We will continue to monitor our Charah 
Solutions trade name for any triggering events or other signs of impairment. We may be required to perform additional impairment testing based 
on changes in the economic environment, disruptions to our business, significant declines in our operating results and other factors that could 
result in impairment charges in the future. Although management cannot predict when improvements in macroeconomic conditions will occur, if 
contract awards decline significantly in the future or if operational activity deteriorates significantly from current levels, it is reasonably likely the 
Company will be required to record impairment charges in the future. 
Deferred Taxes, Valuation Allowance 
As discussed in Note 21, Income Taxes, to our consolidated financial statements, deferred tax assets and liabilities are recognized for 
the expected future tax consequences of events that have been recognized in our consolidated financial statements or tax returns. We record a 
valuation allowance to reduce certain deferred tax assets to amounts that are more-likely-than-not to be realized. We evaluate the realizability of 
our deferred tax assets by assessing the valuation allowance and adjusting the amount of such allowance, if necessary. The factors used to 
assess the likelihood of realization include our forecast of future taxable income exclusive of reversing temporary differences and carryforwards, 
future reversals of existing 
45

 
 
taxable temporary differences and available tax planning strategies that could be implemented to realize the net deferred tax assets. 
Based on the available evidence as of December 31, 2021 and 2020, we could not conclude it is more likely than not certain deferred 
tax assets will be realized. Therefore, a valuation allowance of $19.9 million and $17.2 million, respectively, was recorded against our deferred 
tax assets. We will continue to evaluate the need for a valuation allowance on our deferred tax assets in future periods. 
Asset Retirement Obligations 
The Company has land and structural fill assets with corresponding obligations to restore such assets at the end of their operation. 
Estimating the future closure and post-closure costs is difficult and requires management to make estimates and judgments because these 
obligations are over many years in the future. Asset retirement obligations (“ARO”) associated with retiring long-lived assets are recognized as a 
liability in the period in which a legal obligation is incurred and becomes determinable. The ARO liability reflects the estimated present value of 
the closure and post-closure activities associated with the Company’s land and structural fill assets. The Company utilizes current retirement 
costs to estimate the expected cash outflows for retirement obligations. 
Inherent in the present value calculation are numerous assumptions and judgments, including the ultimate settlement amounts, inflation 
factors, credit-adjusted discount rates, timing of settlement, and changes in the legal, regulatory, environmental and political environments. To 
the extent future revisions to these assumptions impact the present value of the existing ARO liability, a corresponding adjustment is made to the 
land and/or structural fill balance. Accretion expense is recognized over time as the discounted liability is accreted to its expected settlement 
value. Gains and losses on ARO settlement are recognized as specific remediation tasks are performed. These gains and losses are determined 
based on the differences between the estimated costs used in the measurement of the fair value of the Company's AROs and the actual costs 
incurred for specific remediation tasks recognized on a proportionate basis. 
 
Recent Accounting Pronouncements 
Please see Note 2, “Summary of Significant Accounting Policies—Recently Adopted Accounting Pronouncements” and “Summary of 
Significant Accounting Policies—Recently Issued Accounting Pronouncements” to our historical consolidated financial statements as of and for 
the years ended December 31, 2021 and 2020, included elsewhere herein, for a discussion of recent accounting pronouncements. 
Under the JOBS Act, we meet the definition of an “emerging growth company,” which allows us to have an extended transition period for 
complying with new or revised accounting standards under Section 107(b) of the JOBS Act. We intend to take advantage of all of the reduced 
reporting requirements and exemptions, including the longer phase-in periods for adopting new or revised financial accounting standards under 
Section 107(b) of the JOBS Act until we are no longer an emerging growth company. 
 
Item 7A. Quantitative and Qualitative Disclosure About Market Risks 
Market risk is the risk of loss arising from adverse changes in market rates and prices. Currently, our market risks relate to potential 
changes in the fair value of our long-term debt due to fluctuations in applicable market interest rates. We expect that in the future, our market risk 
exposure generally will be limited to those risks that arise in the normal course of business, as we do not engage in 
speculative, non-operating transactions, nor do we utilize financial instruments or derivative instruments for trading purposes. 
Interest Rate Risk 
Our cash consists of cash in readily available checking accounts. Outstanding borrowing under our Credit Agreement bear interest at a 
variable rate; however, there were no outstanding borrowing on our Credit Agreement as of December 31, 2021. As a result, the fair value of our 
long-term debt is relatively insensitive to interest rate changes. 
Credit Risk 
While we are exposed to credit risk in the event of non-performance by counter parties, the majority of our customers are 
investment-grade companies, and we do not anticipate non-performance. We mitigate the associated credit risk by performing credit evaluations 
and monitoring the payment patterns of our customers. 
Off-Balance Sheet Arrangements 
We currently have no material off-balance sheet arrangements except for operating leases as referenced in “Item 7. Management’s 
Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources.”

Item 9A. Controls and Procedures 
Evaluation of Disclosure Controls and Procedures 
The Company maintains disclosure controls and procedures (as defined in Rule 13a-15(e) or Rule 15d-15(e) under the Exchange Act) 
that are designed to ensure that information required to be disclosed in the Company’s reports under the Exchange Act is processed, recorded, 
summarized, and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and 
communicated to management, including the Chief Executive Officer and Chief Financial Officer, as appropriate, to allow for timely decisions 
regarding required disclosure. 
As required by SEC Rule 13a-15(b), the Company carried out an evaluation, under the supervision and with the participation of 
management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the disclosure 
controls and procedures. Based on the foregoing, the Company’s Chief Executive Officer and Chief Financial Officer concluded, as of that time, 
the disclosure controls and procedures were not effective due to the material weakness in internal control over financial reporting described 
below. 
Notwithstanding the identified material weakness, management, including our Chief Executive Officer and Chief Financial Officer, 
believes the consolidated financial statements included in this Annual Report fairly represent, in all material respects, our financial condition, 
results of operations and cash flows as of and for the periods presented in accordance with U.S. Generally Accepted Accounting Principles. 
Management’s Annual Report on Internal Control Over Financial Reporting 
Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 
13a-15(f) and 15d-15(f) of the Exchange Act). The Company’s internal control over financial reporting is a process designed under the 
supervision of its Chief Executive Officer (Principal Executive Officer) and Chief Financial Officer and Treasurer (Principal Financial Officer) and 
effected by the Company’s Board of Directors, management and other personnel, to provide reasonable assurance regarding the reliability of 
financial reporting and the preparation of its financial statements for external reporting purposes in accordance with GAAP. 
The Company’s internal control over financial reporting includes policies and procedures that pertain to the maintenance of records that, 
in reasonable detail, accurately and fairly reflect transactions and dispositions of the Company’s assets; provide reasonable assurance that 
transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that receipts and 
expenditures of the Company are being made only following authorizations of management and the directors; and 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 its financial statements. 
Management evaluated the effectiveness of the Company’s internal control over financial reporting as of December 31, 2021 based on 
the framework established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the 
Treadway Commission. Based on this evaluation, management, with the participation of the Chief Executive Officer and Chief Financial Officer, 
concluded that, as of December 31, 2021, the Company’s internal control over financial reporting was not effective due to the material weakness 
described below. 
This annual report does not include an attestation report of the Company’s registered public accounting firm due to an exemption for 
emerging growth companies under the JOBS Act. 
Material Weakness in Internal Control over Financial Reporting 
Management identified a material weakness in our internal control over financial reporting in connection with our assessment as of and 
for the year ended December 31, 2021. A material weakness is a deficiency, or combination of deficiencies, in internal control over financial 
reporting such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be 
prevented or detected on a timely basis. 
We identified the following control deficiencies which aggregate to a material weakness: (i) lack of a sufficient number of trained 
resources with assigned responsibilities and accountability for the design and operation of internal controls over financial reporting; (ii) lack of 
formal and effective controls over certain financial statement account balances; (iii) lack of user profiles to ensure adequate restriction of users to 
perform only transactions that are consistent with their function; and (iv) 
47

 
 
lack of appropriate segregation of duties within the accounting and finance functions, including order to cash, process to pay and payroll 
business processes. 
Management's Remediation Plan 
We have identified and implemented, and continue to implement, certain remediation efforts to improve the effectiveness of our internal 
control over financial reporting and disclosure controls and procedures. These remediation efforts are ongoing. The following remedial actions 
have been identified and initiated as of December 31, 2021: 
ƒWe have hired an external consultant to assist us in an evaluation of design and implementation of certain internal controls to address 
the identified deficiencies. 
ƒWe are in the process of hiring additional accounting resources with appropriate levels of experience and reallocating responsibilities 
across the finance organization. This measure will provide for appropriate segregation of duties and will ensure that the appropriate 
level of knowledge and experience will be applied based on the risk and complexity of transactions and tasks under review. 
ƒWe are revising user profiles within our accounting systems to ensure appropriate segregation of duties are in place. 
In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no 
matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is 
required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. 
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. In addition, 
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. Therefore, even those systems determined to be 
effective can provide only reasonable assurance with respect to financial statement preparation and presentation. As we continue to evaluate 
and take actions to improve our internal control over financial reporting, we will further refine our remediation plan and take additional actions to 
address control deficiencies or modify certain of the remediation measures described above. 
While progress has been made to enhance our internal control over financial reporting, we are still in the process of designing, 
implementing, documenting, and testing the effectiveness of these processes, procedures and controls. Additional time is required to complete 
the implementation and to assess and ensure the sustainability of these procedures. We will continue to devote time and attention to these 
remedial efforts. However, the material weakness cannot be considered remediated until the applicable remedial controls are fully implemented, 
have operated for a sufficient period of time and management has concluded that these controls are operating effectively through testing. 
Changes in Internal Control Over Financial Reporting 
Aside from the identification of the material weakness described above and the actions taken as described in Management's 
Remediation Plan above to improve the Company’s internal control over financial reporting, there were no changes in our internal control over 
financial reporting identified in connection with the evaluation required by Rules 13a-15(d) and 15d-15(d) of the Exchange Act that occurred 
during the quarter ended December 31, 2021 that have materially affected or are reasonably likely to materially affect, our internal control over 
financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 
 
To the shareholders and the Board of Directors of Charah Solutions, Inc. 
 
Opinion on the Financial Statements 
 
We have audited the accompanying consolidated balance sheets of Charah Solutions, Inc and subsidiaries (the "Company") as of December 31, 
2021 and 2020, the related consolidated statements of operations, stockholders’ equity, and cash flows for each of the three years in the period 
ended December 31, 2021, and the related notes and the schedule listed in the Index at Item 15 (collectively referred to as the "financial 
statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of 
December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 
2021, in conformity with accounting principles generally accepted in the United States of America. 
 
Basis for Opinion 
 
These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's 
financial statements 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 audit to obtain 
reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is 
not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are 
required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the 
effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. 
 
Our audits included performing procedures to assess the risks of material misstatement of the 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 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 financial statements. We believe that our audits provide a 
reasonable basis for our opinion. 
 
/s/ Deloitte & Touche LLP 
 
Louisville, Kentucky

We have served as the Company’s auditor since 2017.

1. Nature of Business and Basis of Presentation 
Organization 
Charah Solutions, Inc. (together with its wholly-owned subsidiaries, “Charah Solutions,” the “Company,” “we,” “us,” or “our”), is a holding 
company formed in Delaware in January 2018. The Company's majority shareholder is Bernhard Capital Partners Management, LP and its 
affiliates (“BCP”). BCP owns approximately 54% of the total voting power of our outstanding shares of common stock and all of the outstanding 
Series A Preferred Stock (“Preferred Stock”), which is convertible at BCP's option at any time following the three-month anniversary of the 
issuance date into shares of common stock. 
Description of Business Operations 
The Company is a leading national service provider of mission-critical environmental services and byproduct recycling to the power 
generation industry, enabling our customers to address challenges related to the remediation of coal ash ponds and landfills at open and closed 
power plant sites while continuously operating and providing necessary electric power to communities nationwide. Services offered include a 
suite of remediation and compliance services, byproduct services, raw material sales and Environmental Risk Transfer (“ERT”) services. The 
Company has corporate offices in Kentucky and North Carolina and principally operates in the eastern and mid-central United States. 
The accompanying consolidated financial statements include the assets, liabilities, stockholders’ equity, members’ equity, and results of 
operations of the Company and its consolidated subsidiaries. Intercompany transactions and balances have been eliminated in consolidation. 
Under the Jumpstart Our Business Startups Act (the “JOBS Act”), the Company meets the definition of an “emerging growth company,” 
which allows the Company to have an extended transition period for complying with new or revised accounting standards pursuant to 
Section 107(b) of the JOBS Act. The Company intends to take advantage of all of the reduced reporting requirements and exemptions, including 
the longer phase-in periods for the adoption of new or revised financial accounting standards under Section 107 of the JOBS Act until the 
Company is no longer an emerging growth company. Among other things, we are not required to provide an auditor attestation report on the 
assessment of the internal control over financial reporting under Section 404(b) of the Sarbanes-Oxley Act of 2002 and our disclosure 
obligations regarding executive compensation may be reduced. We may take advantage of these provisions until the last day of our fiscal year 
following the fifth anniversary of the IPO, or December 31, 2023. However, if certain events occur before the end of such five-year period, 
including if we become a “large accelerated filer,” our annual gross revenue exceeds $1.07 billion, or we issue more than $1.0 billion of 
non-convertible debt in any three-year period, we will cease to be an emerging growth company before the end of such five-year period. 
Discontinued Operations 
On November 19, 2020, the Company sold its Allied subsidiary engaged in maintenance, modification and repair services to the nuclear 
and fossil power generation industry to an affiliate of BCP (the “Purchaser”), the Company’s majority shareholder, in an all-cash deal for $40,000 
(the “Allied Transaction”), subject to adjustments for working capital and certain other adjustments as set forth in the purchase agreement (the 
"Purchase Agreement"). 
Discontinued operations comprise those activities that have been disposed of during the period and represent a separate major line of 
business that can be clearly distinguished for operational and financial reporting purposes. Accordingly, the Consolidated Balance Sheets, 
Statements of Operations, and the Notes to Consolidated Financial Statements reflect the Allied results as discontinued operations for all 
periods presented. Unless otherwise specified, disclosures in these consolidated financial statements reflect continuing operations only. The 
Consolidated Statements of Cash Flows include both continuing and discontinued operations. Refer to Note 3, Discontinued Operations, for 
further information on the discontinued operations relating to the Allied Transaction. 
Segment Information 
After the Allied Transaction, the Company operates as one reportable segment, reflecting the suite of end-to-end services we offer our 
utility partners and how our Chief Operating Decision Maker (“CODM”) reviews consolidated financial information to evaluate results of 
operations, assess performance and allocate resources. Due to the nature of the Company’s business, the Company's Chief Executive Officer, 
who is also the CODM, evaluates the performance of the Company and allocates resources of the Company based on consolidated gross profit, 
general and administrative expenses, balance sheet, 
F-8

 
 
CHARAH SOLUTIONS, INC. 
Notes to Consolidated Financial Statements, continued 
(amounts in thousands except per share data) 
 
 
liquidity, capital spending, safety statistics and business development reports for the Company as a whole. Since the Company has a single 
operating segment, all required financial segment information can be found in the consolidated financial statements. 
We provide the following services through our one segment: remediation and compliance services, byproduct services, raw material 
sales and ERT transfer services. Remediation and compliance services are associated with our customers’ need for multi-year environmental 
improvement and sustainability initiatives, whether driven by regulatory requirements, power generation customer initiatives or consumer 
expectations and standards. Byproduct services consist of recurring and mission-critical coal ash management and operations for coal-fired 
power generation facilities while also supporting both our power generation customers’ desire to recycle their recurring and legacy volumes of 
coal combustion residuals (“CCRs”), commonly known as coal ash, and our ultimate end customers’ need for high-quality, cost-effective 
supplemental cementitious materials (SCMs) that provide a sustainable, environmentally-friendly substitute for Portland cement in concrete. Our 
raw materials sales provide customers with the materials essential to their business while also providing the sourcing, logistics, and 
management needed to facilitate these raw materials transactions around the globe. ERT services represent an innovative solution designed to 
meet the evolving and increasingly complex needs of utility customers' evolving and increasingly complex plant closure and environmental 
remediation needs. These customers need to retire and decommission older or underutilized assets while maximizing the asset's value and 
improving the environment. Our ERT services manage the sites' environmental remediation requirements, benefiting the communities and 
lowering the utility customers' costs 
Impact of the COVID-19 Pandemic 
In March 2020, the World Health Organization categorized the disease caused by a novel coronavirus (“COVID-19”) to be a pandemic. 
Management continues to evaluate the impact of the COVID-19 pandemic and has concluded that while it is reasonably possible that the virus 
could have a negative effect on the Company’s financial position and results of its operations, the specific impact is not readily determinable as 
of the date of these financial statements. The financial statement does not include any adjustments that might result from the outcome of this 
uncertainty. 
On March 27, 2020, the U.S. government enacted the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”), which 
includes modifications to the limitation on business interest expense and net operating loss carryforward provisions and provides a payment 
delay of certain employer payroll taxes during 2020. The Company deferred $1,637 of employer payroll taxes otherwise due in 2020 with 50% 
due and paid by December 31, 2021 and the remaining 50% due by December 31, 2022. The CARES Act did not have a material impact on the 
Company’s consolidated financial statements. 
 
2. Summary of Significant Accounting Policies 
Management’s Use of Estimates 
The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of 
America (“GAAP”) requires management to make estimates and assumptions, in particular estimates of legal reserves, costs to complete 
contracts in process, contract modifications and unapproved change orders, that affect the reported amounts in the consolidated financial 
statements and accompanying notes. Actual results could differ from those estimates. 
Balance Sheet Classification 
The Company includes in current assets and liabilities contract assets, contract liabilities and retainage amounts payable, which may 
extend beyond one year. One year is used as the basis for classifying all other assets and liabilities. 
Cash 
The Company maintains cash in bank deposit accounts which, at times, may exceed federally insured limits. The Company has not 
experienced any losses in such accounts. The Company believes it is not exposed to any significant credit risk on cash. 
Restricted Cash 
We maintain restricted cash in non-interest bearing escrow accounts for specific remediation and compliance projects, cash collateral for 
letters of credit, and insurance-related items. This cash becomes unrestricted as project milestones are completed in accordance with each 
project's defined project schedule, or when credit agreements requiring cash collateral are terminated. As of December 31, 2021 and 2020, 
restricted cash in these accounts held $34,908 and $4,424, respectively.

Trade Accounts Receivable, Net 
Trade accounts receivable, net consist of amounts due from customers. An allowance for doubtful accounts is recorded to the extent it is 
probable that a portion of a particular account will not be collected. Management determines the allowance for doubtful accounts by evaluating 
individual customer receivables and considering a customer’s financial condition, credit history, and current economic conditions. An allowance 
for doubtful accounts of $146 and $467 was included in trade accounts receivable, net as of December 31, 2021 and 2020, respectively. 
Trade accounts receivable balances are considered past due based upon contract or invoice terms and are charged off when deemed 
uncollectible. The Company does not charge interest on customer accounts and generally does not require collateral on sales and services 
during the normal course of business. The Company has the right to file liens on the owner’s property with regard to certain construction 
contracts. 
Inventory 
Inventories, mainly comprising ash for resale, are valued using the first-in, first-out (“FIFO”) method. Inventories are stated at the lower 
of cost or net realizable value. 
Property and Equipment 
Property and equipment are stated at cost. Construction-in-progress represents costs incurred on the construction of assets that have 
not been completed or placed in service as of the end of the year. We evaluate the long-lived assets each reporting period to determine whether 
events and circumstances continue to support the asset's carrying value. Depreciation is provided principally by the straight-line method over the 
estimated useful lives of the assets as follows: 
  
 
 
  
   
 
Plant, machinery and equipment 
 
2 - 15 years 
Vehicles 
 
2 - 10 years 
Office equipment 
 
2 - 10 years 
Buildings and leasehold improvements 
 
5 - 40 years 
Capital lease assets 
3 - 7 years 
Repair and maintenance costs are expensed as incurred and expenditures for improvements are capitalized. 
Asset Retirement Obligations 
Asset retirement obligations (“ARO”) associated with retiring long-lived assets are recognized as a liability in the period in which a legal 
obligation is incurred and becomes determinable. The ARO liability reflects the estimated present value of the closure and post-closure activities 
associated with the Company’s land and structural fill assets. The Company utilizes current retirement costs to estimate the expected cash 
outflows for retirement obligations. 
Inherent in the present value calculation are numerous assumptions and judgments, including the ultimate settlement amounts, inflation 
factors, credit-adjusted discount rates, timing of settlement, and changes in the legal, regulatory, environmental and political environments. To 
the extent future revisions to these assumptions impact the present value of the existing ARO liability, a corresponding adjustment is made to the 
land and/or structural fill balance. Accretion expense is recognized over time as the discounted liability is accreted to its expected settlement 
value. Gains and losses on ARO settlement are recognized as specific remediation tasks are performed. These gains and losses are determined 
based on the differences between the estimated costs used in the measurement of the fair value of the Company's AROs and the actual costs 
incurred for specific remediation tasks recognized on a proportionate basis. 
Goodwill and Indefinite Lived Intangible Assets 
Goodwill represents the excess purchase price over the estimated fair value of net assets acquired in a business combination. Our 
intangible assets in the Consolidated Balance Sheets as of December 31, 2021 and 2020 include a trade name that is considered to have an 
indefinite life. 
Goodwill and indefinite-lived intangible assets are not amortized but instead are tested for impairment at least annually or more often if 
events or changes in circumstances indicate that the fair value of the asset may have decreased below its carrying value.

Goodwill is tested at the reporting unit level, which has been determined to be the Company. When performing its goodwill impairment 
test, the Company considers a qualitative assessment, when appropriate, and a quantitative assessment using the market approach and its 
market capitalization when determining the fair value of the reporting unit. 
We evaluate the indefinite-lived trade name each reporting period to determine whether events and circumstances continue to support 
an indefinite useful life. When performing its indefinite-lived intangible asset impairment test, the Company considers a qualitative assessment, 
when appropriate, and a quantitative assessment using the relief-from-royalty method, an income approach, that estimates the present value of 
royalty income that could be hypothetically earned by licensing the brand name to a third party over the remaining useful life. 
The assets will be written down to their implied fair value if the carrying value exceeds its fair value. 
Definite-Lived Intangible Assets 
Definite-lived intangible assets are comprised of our customer relationships. We evaluate our definite-lived intangible asset each 
reporting period to determine whether events and circumstances indicate that a triggering event has occurred that suggests that the fair value of 
the asset is below its carrying value. These assets are amortized on a straight-line basis over their estimated useful lives, as shown in the table 
below.

Fair Value Disclosure 
The Company follows Accounting Standards Codification (“ASC”) 820, Fair Value Measurements, which provides a framework for 
measuring and disclosing fair value under generally accepted accounting principles. ASC 820 requires disclosures about the fair value of assets 
and liabilities recognized in the balance sheet in periods subsequent to initial recognition, whether the measurements are made on a recurring 
basis or on a nonrecurring basis. 
ASC 820 defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the 
principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. 
ASC 820 also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of 
unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value. 
Fair Value Hierarchy 
Level 1 - Valuation is based on quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to 
access at the measurement date. Level 1 assets and liabilities generally include debt and equity securities that are traded in an active exchange 
market. Valuations are obtained from readily available pricing sources for market transactions involving identical assets and liabilities. 
Level 2 - Valuation is based on inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either 
directly or indirectly. The valuation may be based on quoted prices for similar assets and liabilities; quoted prices in markets that are not active, 
or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability. 
Level 3 - Valuation is based on unobservable inputs that are supported by little or no market activity and that are significant to the fair 
value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, 
discounted cash flow methodologies, or similar techniques, as well as instruments for which determination of fair value requires significant 
management judgment or estimation. 
In determining the appropriate levels, the Company performs a detailed analysis of assets and liabilities that are subject to ASC 820. 
The Company's contingent payments for acquisitions and interest rate swap are the only assets or liabilities subject to fair value measurements 
on a recurring basis. The Company may also be required, from time to time, to measure certain other financial and non-financial assets and 
liabilities at fair value on a non-recurring basis in accordance with GAAP. There have been no transfers between levels of the fair value hierarchy 
during the years ended December 31, 2021 and 2020.

The fair value of the Company's 8.50% Senior Notes due 2026 (the "Notes") were estimated using quoted prices based on current 
transactions for similar debt, which are considered to be Level 2 measurements. The Notes had a fair value and carrying value of $131,760 and 
$135,000, respectively, as of December 31, 2021. 
The book value of our outstanding equipment and other notes approximated fair value as December 31, 2021 based on consideration of 
recently executed transactions for similar debt, which are considered to be Level 2 measurements. The equipment notes had a fair value and 
carrying value of $17,672 as of December 31, 2021. 
Our outstanding debt as of December 31, 2020 primarily bore interest at variable rates and book value approximated fair value, which 
were considered to be Level 2 measurements. 
The carrying amounts and fair values of the Company’s recurring fair value measurements as of December 31, 2021 and 2020 are

1.As of December 31, 2021 and 2020, the fair value of the contingent payments for acquisitions was estimated at the acquisition date 
using the present value of future payments and a discount rate in effect at the time of the acquisition. This analysis is updated at 
each reporting date to determine if any changes to the fair value are required and is considered to be a Level 3 measurement. 
2.As of December 31, 2020, the fair value of the interest rate swap was measured based on observable market data, which were 
considered to be Level 2 measurements. 
The Company's non-recurring level 3 fair value measurements consist of the measurement of AROs as described in Notes 5 and 7, the 
valuation of goodwill, intangible assets, and real estate, property and equipment, net as described in Notes 6 and 10 and the measurement of 
the preferred stock paid-in-kind dividends as described in Note 14. 
Debt Issuance Costs 
Debt issuance costs associated with our various credit agreements are amortized as interest expense over the term of the applicable 
agreement. Debt issuance costs related to the Notes are presented as a direct deduction from the carrying amount of the related liability in the 
Consolidated Balance Sheet. Debt issuance costs related to the Asset-Based Lending Credit Agreement (the “Credit Agreement”) are included 
in other assets in the Consolidated Balance Sheet. 
Freight Costs 
Freight costs charged to customers are included in revenue. Costs incurred by the Company for freight are included in cost of sales. 
Leases 
Leases are accounted under ASC 840, Leases, and are categorized as either operating or capital leases at inception. Operating lease 
costs are recognized on a straight-line basis over the term of the lease. For capital leases, an asset and a corresponding liability are established 
for the present value at the beginning of the lease term of minimum lease payments during the lease term, excluding any executory costs. If the 
present value of the minimum lease payments exceeds the fair value of the leased property at lease inception, the amount measured initially as 
the asset and obligation shall be the fair value. The capital lease obligation is amortized over the life of the lease.

Income Taxes 
Income taxes are accounted for in accordance with ASC 740. Income tax expense, or benefit, is calculated using the asset and liability 
method under which deferred tax assets and liabilities are recorded based on the difference between the financial statement and tax basis of 
assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. 
The Company assesses its deferred tax assets each quarter to determine whether the assets are more likely than not (probability of 
more than 50%) realizable under ASC 740. The Company is required to record a valuation allowance for any portion of the tax assets that, 
based on the assessment, are not more likely than not realizable. The assessment considers, among other things, earnings in prior periods, 
forecasts of future taxable income, statutory carryforward periods, and tax planning strategies, to the extent feasible. The realization of deferred 
tax assets largely depends part on the generation of future taxable income during the periods in which the differences become deductible. The 
value of the deferred tax assets will also depend on applicable income tax rates. Judgment is required in determining the future tax 
consequences of events that have been recognized in the financial statements. Differences between anticipated and actual outcomes of these 
future tax consequences could have a material impact on the financial statements. Changes in existing tax laws and tax rates also affect actual 
tax results and the valuation of deferred tax assets over time. 
Stock-Based Compensation Plans 
The Company accounts for its stock-based compensation plans as equity-classified plans, in accordance with the fair value recognition 
provisions of ASC 718, Compensation-Stock Compensation. The Company utilizes the Black-Scholes model, which requires the input of 
subjective assumptions. These assumptions include estimating (i) the volatility of the common stock price over the expected term, (ii) the 
expected term, and (iii) expected dividends. Where the vesting of the stock is also based upon performance measures, management determines 
the likelihood of meeting such measures. Changes in the subjective assumptions can materially affect the estimate of the fair value of 
stock-based compensation and, consequently, the related amounts recognized on the Consolidated Statements of Operations. 
Stock-based compensation expense is recognized in general and administrative expenses. 
Revenue from Contracts with Customers 
Revenue is measured based on the amount of consideration specified in a contract with a customer. Revenue is recognized when our 
performance obligations under the terms of the contract are satisfied, which generally occurs with the transfer of control of the goods or services 
to the customer. 
Contract Combination 
To determine revenue recognition for contracts, we evaluate whether two or more contracts should be combined and accounted for as 
one single contract and whether the combined or single contract should be accounted for as more than one performance obligation. This 
evaluation requires significant judgment, and the decision to combine a group of contracts or separate a combined or single contract into multiple 
performance obligations could change the amount of revenue and profit recorded in a given period. Contracts are considered to have a single 
performance obligation if the promise to transfer the individual goods or services is not separately identifiable from other promises in the 
contracts primarily because we provide a service that involves multiple inter-related and integrated tasks to achieve the completion of a specific, 
single project. We allocate the transaction price to each performance obligation for contracts with multiple performance obligations using our 
best estimate of the stand-alone selling price of each distinct good or service in the contract. 
Sales and Services Contracts 
For sales and service contracts where we have the right to consideration from the customer in an amount that corresponds directly with 
the value received by the customer based on our performance to date, revenue is recognized at a point in time when services are performed and 
contractually billable. Certain service contracts contain provisions dictating fluctuating rates per unit for the certain services in which the rates are 
not directly related to changes in the Company’s effort to perform under the contract. We recognize revenue based on the stand-alone selling 
price per unit for such contracts, calculated as the average rate per unit over the term of those contractual rates. This creates a contract asset or 
liability for the difference between the revenue recognized and the amount billed to the customer. 
Under the typical payment terms of our services contracts, amounts are billed as work progresses in accordance with agreed-upon 
contractual terms, at periodic intervals (e.g., weekly, biweekly or monthly).

Construction Contracts 
We recognize revenue over time, as performance obligations are satisfied, for substantially all of our construction contracts due to the 
continuous transfer of control to the customer. For most of our construction contracts, the customer contracts with us to provide a service that 
involves multiple inter-related and integrated tasks to complete a specific, single project and is therefore accounted for as a single performance 
obligation. We recognize revenue using the cost-to-cost input method, based primarily on contract costs incurred to date compared to total 
estimated contract costs. This method is the most accurate measure of our contract performance because it depicts the company’s performance 
in transferring control of goods or services promised to customers according to a reasonable measure of progress toward complete satisfaction 
of the performance obligation. 
Contract costs include all direct material, labor and subcontractor costs and indirect costs related to contract performance. The costs 
incurred that do not relate directly to transferring a service to the customer are excluded from the input method used to recognize revenue. 
Project mobilization costs are generally charged to the project as incurred when they are an integrated part of the performance obligation being 
transferred to the client. Pre-contract costs are expensed as incurred unless they are expected to be recovered from the client. 
The payment terms of our construction contracts from time to time require the customer to make advance payments as well as interim 
payments as work progresses. The advance payment generally is not considered a significant financing component as we expect to recognize 
those amounts in revenue within a year of receipt as work progresses on the related performance obligation. 
Variable Consideration 
It is common for our contracts to contain contract provisions that give rise to variable consideration such as unpriced change orders or 
volume discounts that may either increase or decrease the transaction price. We estimate the amount of variable consideration at the expected 
value or most likely amount, depending on which is determined to be more predictive of the amount to which the Company will be entitled. 
Variable consideration is included in the transaction price when it is probable that a significant reversal of cumulative revenue recognized will not 
occur or when the uncertainty associated with the variable consideration is resolved. Our estimates of variable consideration and determination 
of whether to include such amounts in the transaction price are based largely on our assessment of legal enforceability, anticipated performance, 
industry business practices, and any other information (historical, current or forecasted) that is reasonably available to us. Variable consideration 
associated with unapproved change orders is included in the transaction price only to the extent of costs incurred. 
We provide limited warranties to customers for work performed under our contracts. Such warranties are not sold separately, assure that 
the services comply with the agreed-upon specifications and legal requirements and do not provide customers with a service in addition to 
assurance of compliance with agreed-upon specifications. Accordingly, these types of warranties are not considered to be separate performance 
obligations. Historically, warranty claims have not resulted in material costs incurred. 
Contract Estimates and Modifications 
Due to the nature of the work required to be performed on many of our performance obligations, the estimation of total revenue and cost 
at completion is complex, subject to many variables and requires significant judgment. As a significant change in one or more of these estimates 
could affect the profitability of our contracts, we routinely review and update our contract-related estimates through a disciplined project review 
process in which management reviews the progress and execution of our performance obligations and the estimated costs at completion. As 
part of this process, management reviews information including, but not limited to, outstanding contract matters, progress towards completion, 
program schedule and the associated changes in estimates of revenue and costs. Management must make assumptions and estimates 
regarding the availability and productivity of labor, the complexity of the work to be performed, the availability and cost of materials, the 
performance of subcontractors, and the availability and timing of funding from the customer, along with other risks inherent in performing 
services under all contracts where we recognize revenue over-time using the cost-to-cost method. 
We recognize changes in contract estimates on a cumulative catch-up basis in the period in which the changes are identified. Such 
changes in contract estimates can result in the recognition of revenue in a current period for performance obligations that were satisfied or 
partially satisfied in prior periods. Changes in contract estimates may also result in the reversal of previously recognized revenue if the current 
estimate differs from the previous estimate. If at any time the estimate of contract profitability indicates an anticipated loss on the contract, we 
recognize the total loss in the period it is identified.

Contracts are often modified to account for changes in contract specifications and requirements. Most of our contract modifications are 
for goods or services that are not distinct from existing contracts due to the significant integration provided in the context of the contract and are 
accounted for as if they were part of the original contract. The effect of a contract modification on the transaction price and our measure of 
progress for the performance obligation to which it relates is recognized as an adjustment to revenue (either as an increase in or a reduction of 
revenue) on a cumulative catch-up basis. We account for contract modifications when the modification results in the promise to deliver additional 
goods or services that are distinct and the increase in the price of the contract is for the same amount as the stand-alone selling price of the 
additional goods or services included in the modification. 
We evaluate our contracts whether we are acting as the principal or as the agent when providing services, which we consider in 
determining if revenue should be reported on a gross or net basis. We determine the Company to be a principal if we control the specified 
service before that service is transferred to a customer. 
Contract Assets and Liabilities 
Billing practices are governed by each project's contract terms based upon costs incurred, achievement of the milestones or 
predetermined schedules. Billings do not necessarily correlate with revenue recognized over time using the cost-to-cost input method. Contract 
assets include unbilled amounts typically resulting from revenue under long-term contracts when the revenue recognized exceeds the amount 
billed to the customer. Contract liabilities consist of billings in excess of revenue recognized as well as deferred revenue. 
Contract assets also include retainage, which represents amounts withheld by our clients from billings according to provisions in the 
contracts and may not be paid to us until the completion of specific tasks or the completion of the project and, in some instances, for even longer 
periods. 
Our contract assets and liabilities are reported in a gross position on a contract-by-contract basis at the end of each reporting period. We 
include in current assets and liabilities contract assets and liabilities, which may extend beyond one year. 
Recently Issued Accounting Pronouncements 
In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), requiring all leases to be recognized on the balance sheet as 
a right-of-use asset and a lease liability unless the lease is a short-term lease (generally a lease with a term of 12 months or less). At the 
commencement date of the lease, the Company will recognize: (i) a lease liability for the Company’s obligation to make payments under the 
lease agreement, measured on a discounted basis; and (ii) a right-of-use asset that represents the Company’s right to use, or control the use of, 
the specified asset for the lease term. This ASU originally required recognition and measurement of leases at the beginning of the earliest period 
presented using a modified retrospective transition method. In July 2018, the FASB issued ASU No. 2018-11, which provided an additional (and 
optional) transition method that permits the application of this ASU at the adoption date with recognition of a cumulative-effect adjustment to the 
opening balance of retained earnings in the period of adoption. In June 2020, the FASB issued ASU No. 2020-05 and delayed the effective date 
of this ASU, extending the effective date for non-public business entities, and making the ASU effective for the Company for the fiscal year 
ending December 31, 2022, and interim periods within the fiscal year ending December 31, 2023, with early adoption permitted. The Company 
has not yet selected a transition method and, while we are still in the process of assessing the impact of this new standard on our consolidated 
financial position, results of operations and cash flows, we expect the adoption of this standard will have a material impact on our consolidated 
financial position due to the recognition of the right-of-use asset and lease liability related to operating leases. We had operating leases with 
remaining rental payments of approximately $29,106 as of December 31, 2021. The discounted minimum remaining rental payments will be the 
starting point for determining the right-of-use asset and lease liability. 
In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326) - Measurement of Credit Losses on 
Financial Instruments, which introduces a new model for recognizing credit losses on financial instruments based on an estimate of current 
expected credit losses. The new model will apply to: (1) loans, accounts receivable, trade receivables, and other financial assets measured at 
amortized cost, (2) loan commitments and certain other off-balance sheet credit exposures, (3) debt securities and other financial assets 
measured at fair value through other comprehensive income, and (4) beneficial interests in securitized financial assets. The amendments 
contained in this ASU will be applied through a modified retrospective approach through a cumulative-effect adjustment to retained earnings as 
of the beginning of the first reporting period in which the guidance is adopted. In November 2018, the FASB issued ASU No. 2018-19, which 
amended the effective date of ASU No. 2016-13 and clarified that receivables arising from operating leases are not within the scope of Subtopic 
326-20. In October 2019, the FASB delayed the effective date of this ASU, extending the effective date for non-public

business entities and making the ASU effective for the Company for the fiscal year ending December 31, 2023, and interim periods therein, with 
early adoption permitted. The Company is currently evaluating the effect that the adoption of this ASU will have on its consolidated financial 
statements. 
In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848) Facilitation of the Effects of Reference Rate 
Reform on Financial Reporting. The ASU provides optional expedients and exceptions for applying GAAP to contract modifications and hedging 
relationships, subject to meeting certain criteria, that reference LIBOR or another rate that is expected to be discontinued. In January 2021, the 
FASB issued ASU No. 2021-01, Reference Rate Reform (Topic 848). This ASU provides supplemental guidance and clarification to ASU No. 
2020-04, and these updates must be adopted concurrently, cumulatively referred to as “Topic 848.” The amendments in Topic 848 are currently 
effective for all entities and upon adoption may be applied prospectively to contract modifications made on or before December 31, 2022. The 
Company is still assessing the impact of Topic 848 on its consolidated financial statements. 
In August 2020, the FASB issued ASU No. 2020-06, Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives 
and Hedging – Contracts in Entity’s Own Equity (Subtopic 815 – 40): Accounting for Convertible Instruments and Contracts in an Entity’s Own 
Equity. This ASU simplifies the guidance on accounting for convertible debt instruments by removing the separation models for convertible debt 
with a cash conversion feature and convertible debt with a beneficial conversion feature. As a result, after adopting the ASU’s guidance, entities 
will not separately present in equity an embedded conversion feature in such debt. Instead, they will account for a convertible debt instrument 
wholly as debt, and for convertible preferred stock wholly as preferred stock unless certain other conditions are met. Also, the ASU requires the 
application of the if-converted method for calculating diluted earnings per share and the treasury stock method will no longer be available. This 
ASU will be effective for the Company for the fiscal year ending December 31, 2024, and interim periods therein, with early adoption permitted. 
The Company is currently evaluating the effect that the adoption of this ASU will have on its consolidated financial statements. 
 
3. Discontinued Operations 
On November 19, 2020, the Company completed the Allied Transaction through an all-cash deal for $40,000, subject to adjustments for 
working capital and certain other adjustments as set forth in the Purchase Agreement. The Allied Transaction was approved by a special 
committee of the Company’s board of directors consisting solely of independent directors, which obtained a fairness opinion in connection with 
the Allied Transaction. This Allied Transaction has been treated as a sale to an entity under common control, with $25,506 recognized as a 
contribution to equity. 
The parties made customary representations and warranties and have agreed to customary covenants in the Purchase Agreement. The 
Company entered into a non-competition and non-solicitation arrangement under the Purchase Agreement with the Purchaser, subject to 
customary exceptions. In addition, the parties also entered into a Transition Services Agreement pursuant to which the Company provided Allied 
and the Purchaser with certain transition assistance services from the date of the Allied Transaction until April 30, 2021 in exchange for 
payment. The Transition Services Agreement was subsequently amended and extended with certain transition assistance services provided until 
August 30, 2021. In total, the Company received $60 for its performance under the Transition Services Agreement during the year ended 
December 31, 2021. The Company had receivables outstanding from Allied of $0 and $120 at December 31, 2021 and December 31, 2020, 
respectively. In accordance with applicable accounting guidance for the disposal of long-lived assets, the results of the Allied Transaction are 
presented as discontinued operations and, as such, have been excluded from continuing operations for all periods presented. 
The Company received cash proceeds of $37,860, which was net of transaction costs of $1,900 and Allied restricted cash of $240. The 
Company assumed Allied liabilities of $3,500, recorded a $301 increase to paid-in-capital for the income tax impact related to the Allied 
Transaction and recognized accruals of $6,954 for working capital adjustments and $413 for other acquisition-related charges in accrued 
expenses in our Consolidated Balance Sheet as of December 31, 2021. All accruals recognized through the Allied Transaction were paid during 
the year ended December 31, 2021.

4. Revenue 
We disaggregate our revenue from customers by customer arrangement and geographic region as we believe it best depicts how the 
nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors. See details in the tables below.

On December 31, 2021, we had $605,765 in transaction price for existing contracts allocated to remaining performance obligations. We 
expect to recognize approximately 20% of our remaining performance obligations as revenue during 2022, 13% in 2023, 11% in 2024 and 55% 
thereafter. Revenue associated with our remaining performance obligations relates to our construction contracts. The balance of remaining 
performance obligations does not include variable consideration that was determined to be constrained as of December 31, 2021. As of 
December 31, 2021, there were $3,887 in an unapproved change orders associated with project scope changes included in estimated costs at 
completion on certain construction contracts, of which $2,243 were approved after year end. 
 
5. Asset Acquisition 
As part of our ERT service offerings, in February 2021, the Company, through its wholly-owned special purpose vehicle subsidiary 
Gibbons Creek Environmental Redevelopment Group (“GCERG”), closed on an Asset Purchase Agreement (the “APA” or the “Agreement”) with 
Texas Municipal Power Agency to acquire, remediate and redevelop the Gibbons Creek Steam Electric Station and Reservoir (the “Gibbons 
Creek Transaction”). As part of this Agreement, GCERG took ownership of the 6,166-acre area (collectively, the “Purchased Assets”), which 
includes the closed power station and adjacent property, the 3,500-acre reservoir, dam and floodway. GCERG assumed all environmental 
obligations and became responsible for the decommissioning of the coal power plant as well as performing all environmental remediation work 
for the site landfills and ash ponds. At the closing of the APA, GCERG became liable for and expressly fully assumed any and all environmental 
liabilities and environmental compliance, as well as, without limitation, any remediation, investigation, management, mitigation, closure, 
maintenance, reporting, removal, disposal of and any other actions with respect to any hazardous substances at, on, in, under, or emanating 
from the Purchased Assets. 
GCERG, at its discretion, plans to redevelop the property in an environmentally conscious manner that will expand economic activity and 
benefit the surrounding communities, as well as restore the property to a state that will enable it to be put to its best potential use. The existing 
power plant is being demolished, and GCERG is working with the Texas Commission on Environmental Quality to complete all environmental 
remediation required for the property and then plans to redevelop the remediated property within all zoning restrictions. The redevelopment of 
the property is expected to be completed within 34 months from the date of acquisition. 
The Gibbons Creek Transaction was accounted for as an asset acquisition in accordance with ASC 805, Business Combinations, with 
the assumed liabilities net of cash received or owed to us by the seller comprising the purchase price. Since the fair value of the net assets 
acquired exceeded the cost, the Company allocated the difference pro-rata to reduce land, property and equipment, and intangible assets 
acquired on the basis of relative fair values.

The Company has identified asset retirement obligations within the assumed liabilities to be initially measured and valued in accordance 
with ASC 410, Asset Retirement and Environmental Obligations. We developed our estimates of these obligations based on our interpretation of 
current requirements and proposed regulatory changes, and we believe they approximate fair value. Absent quoted market prices, the estimate 
of fair value is based on the best available information, including the results of present value techniques, and is considered to be a Level 3 
measurement. We use professional engineering judgment and estimated prices paid for similar work to determine the fair value of these 
obligations. We are required to recognize these obligations at market prices whether we plan to contract with third parties or perform the work 
ourselves. 
Once we determined the estimated closure and post-closure costs for each asset retirement obligation, we inflation-adjusted those costs 
to the expected time of payment and discounted those expected future costs back to present value using an inflation rate of 3.0%. We 
discounted these costs to present value using the credit-adjusted, risk-free rate effective at the time the obligation was incurred, consistent with 
the expected cash flow approach. Any changes in expectations that result in an upward revision to the estimated cash flows are treated as a 
new liability and discounted at the current rate, while downward revisions are discounted at the historical weighted average rate of the recorded 
obligation. The credit-adjusted, risk-free discount rate used to calculate the present value of an obligation is specific to each individual asset 
retirement obligation. The weighted average rate applicable to our long-term asset retirement obligations related to the Gibbons Creek 
Transaction was approximately 4.5% at the acquisition date. 
Because these obligations are measured at estimated fair value using present value techniques, changes in the estimated cost or timing 
of future final capping, closure, and post-closure activities could result in a material change in these liabilities and results of operations. We 
assess the appropriateness of the estimates used to develop our recorded balances annually or more often if conditions warrant. Differences 
between the estimated costs and actual costs incurred are recognized in earnings as specific obligations are settled. 
Demolition costs will be capitalized as part of the land as incurred as part of preparing the site for sale since, at the acquisition date, (i) 
we planned to demolish the existing structure as part of the redevelopment plan for the acquired property, (ii) demolition is expected to occur 
within a reasonable period of time after the acquisition, and (iii) such expected costs will be incurred to make the land saleable to a third party. 
As part of the acquisition, the Company acquired certain plant, machinery and equipment and vehicles for which management 
committed to a plan to sell. Property and equipment of $193 that was initially classified as held for sale was subsequently sold to third parties 
during the year ended December 31, 2021. 
As of December 31, 2021, the Company has completed the sale of nearly 80% of the real property acreage acquired through the 
Gibbons Creek Transaction. The sale of property included 4,860 acres of the 6,166-acre area, the 3,500-acre reservoir, dam and spillway. The 
Company received net proceeds of $23,575 and recorded a gain on sales of property and

Land, land improvements and structural fill sites include $5,953 of real property acquired in the Gibbons Creek Transaction that the 
Company is actively demolishing and for which depreciation expense is not being recorded. During the year ended December 31, 2021, the 
Company capitalized $4,067 of demolition costs and sold scrap with a cost basis of $2,511. 
Depreciation expense for the years ended December 31, 2021, 2020, and 2019 was $16,718, $17,659, and $17,353, respectively. 
During the fourth quarter of the year ended December 31, 2019, the Company re-assessed the useful life estimates of certain assets 
adjusted to fair value through the application of "push-down" accounting in conjunction with the transaction on January 13, 2017 in which BCP 
acquired a 76% equity position in Charah Management. These assets are depreciated through cost of sales. The Company accounted for this as 
a change in estimate that was applied prospectively, effective as of October 1, 2019. This change in depreciable lives resulted in a decrease in 
the useful lives for these assets and an increase of $941 in depreciation expense during the year ended December 31, 2019. 
Impairment of Long-Lived Assets Other than Goodwill and Intangible Assets 
Long-lived assets other than goodwill and indefinite-lived intangible assets, held and used by the Company, including inventory and 
property and equipment, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the 
assets may not be recoverable. The Company evaluates the recoverability of assets to be held and used by comparing the carrying amount of 
an asset to the future net undiscounted cash flows expected to be generated by the asset to determine if the carrying value is not recoverable. If 
the carrying value is not recoverable, the Company fair values the asset and compares to the carrying value. If the asset is considered to be 
impaired, the impairment loss is measured as the amount by which the carrying amount of the asset exceeds its fair value. 
During the year ended December 31, 2021, the Company determined that a triggering event occurred that indicated that the carrying 
value of certain remaining grinding technology-related equipment may not be recoverable. The fair value of the assets was determined through a 
market approach using the net realizable value of the assets, which indicated that the assets were impaired and resulted in an impairment 
charge of $673. The long-lived assets impaired had no remaining fair value as of December 31, 2021. 
During the year ended December 31, 2020, as a result of the expiration of the option as discussed below, the Company determined that 
a triggering event had occurred that indicated that the asset group may not be recoverable as the option expiration led to a significant adverse 
change in the manner in which the long-lived asset was being used. The Company evaluated the recoverability of the structural fill site assets to 
be held and used by comparing the carrying amount of the asset group to the future net undiscounted cash flows expected to be generated to 
determine if the carrying value is not recoverable. The recoverability test indicated that these assets were not recoverable. The fair value of the 
assets was determined using an income approach of the discounted cash flows expected from the assets and compared to the assets' carrying 
value, which indicated that the assets were impaired and resulted in an impairment charge. The Company recognized an impairment charge

of $6,399. The long-lived assets impaired during the year ended December 31, 2020, had a remaining fair value of $711 before the asset 
retirement obligation reassessment discussed below. 
During the year ended December 31, 2020, as a result of a significant adverse change in the manner in which the long-lived assets were 
being used, the Company determined that certain grinding technology-related equipment and construction in progress assets were no longer 
viable as certain performance sales levels would not be achieved. We concluded that a triggering event had occurred that indicated that the 
asset group may not be recoverable. The fair value of the assets was determined through a market approach using the net realizable value of 
the assets, which indicated that the assets were impaired and resulted in an impairment charge. The Company recognized an impairment 
charge of $9,150. 
During the year ended December 31, 2020, in connection with the impairment of certain grinding technology equipment and construction 
in progress assets, the Company determined that certain slow-moving inventory stored at two locations would no longer be used to create 
finished goods through the use of the previously mentioned technology-related equipment and would be sold to external parties. We concluded 
that a triggering event had occurred that the inventory value may not be recoverable. The fair value was determined through a market approach 
using the net realizable value of the inventory, which indicated that the assets were impaired and resulted in an impairment charge. The 
Company recognized an impairment charge of $2,757, which was recorded in cost of sales in the Consolidated Statement of Operations. As of 
December 31, 2021 and 2020, the inventory impaired during the year ended December 31, 2020 had a remaining fair value of $8 and $1,090, 
respectively. 
Purchase Option Liability 
On January 13, 2017, Charah Management, LLC, a Delaware limited liability company and wholly-owned subsidiary of Charah Solutions 
(“Charah Management”), completed a transaction with BCP, a previously unrelated third party, pursuant to which BCP acquired a 76% equity 
position of Charah Management (“the BCP transaction”). As part of this transaction, Charah Management recorded the fair value of a bargain 
purchase liability for an option held by a customer and a third party for its structural fill sites. The purchase option liability was calculated as the 
difference between the estimated fair value of the structural fill sites at the date of the BCP transaction and the option price to be paid by the 
customer or third party. The purchase options were exercisable after completion of work at the structural fill sites. The bargain purchase option 
was amortized over the structural fill sites’ estimated useful lives. The options expired without exercise in August 2020, and the remaining 
purchase option liability was reduced through amortization expense within general and administrative expenses in our Consolidated Statement 
of Operations.

Sales-type lease 
In March 2021, the Company amended an existing ground lease with a third party concerning one of the Company's structural fill assets 
with a 30-year term expiring on December 31, 2050. The lease includes multiple options that may be exercised at any time during the lease term 
for the lessee to purchase all or a portion of the premises, as well as a put option (the “Put Option”) that provides the Company the option to 
require the lessee to purchase all of the premises at the end of the lease term. 
In accordance with ASC 840, Leases, the Company considered whether this lease, as amended, met any of the following four criteria as 
part of classifying the lease at the amendment date: (a) the lease transfers ownership of the property to the lessee by the end of the lease term; 
(b) the lease contains a bargain purchase option; (c) the lease term is equal to 75 percent or more of the estimated economic life of the lease 
property; and (d) the present value of the minimum lease payments, excluding executory costs, equals or exceeds 90 percent of the excess of 
the fair value of the lease property to the lessor at lease inception. This lease was recorded as a sales-type capital lease due to the Put Option 
provision contained within the lease agreement that represents a transfer of ownership of the property by the end of the lease term. Additionally, 
the Company determined that collectability of the lease payments was reasonably assured and that there were not any significant uncertainties 
related to costs that it has yet to incur with respect to the lease.

At the amendment date of the lease, a discount rate of 3.9% implicit in the sales-type lease was used to calculate the present value of 
the minimum lease payments, which the Company recorded as a lease receivable. The Company recognized a gain of $5,568 within operating 
income in the Consolidated Statements of Operations.

Asset sale agreement 
In June 2021, the Company consummated an asset sale with an unrelated third party in which the Company assigned a lease 
agreement to the purchaser and sold certain grinding-related inventory and fixed assets for an aggregate sale price of $2,852. The Company 
received $1,250 in cash at closing, with the remaining portion to be paid over time on specified dates, with the final payment to be received 36 
months from the closing date. 
The Company determined that the note receivable included a significant financing component. As a result, the sale price and gain on 
sale were determined on a discounted cash flow basis. The Company recognized a gain of $1,187 within gains on sales of fixed assets in the 
Consolidated Statements of Operations.

On March 30, 2018, Charah Management completed a transaction with SCB Materials International, Inc. and affiliated entities (“SCB”), a 
previously unrelated third party, pursuant to which Charah Solutions acquired certain assets and liabilities of SCB for a purchase price of 
$35,000, with $20,000 paid at closing and $15,000 to be paid over time in conjunction with certain performance metrics. The contract also 
contained various mechanisms for a working capital true-up. The acquisition was accounted for under the acquisition method of accounting in 
accordance with ASC 805, Business Combinations, (“ASC 805”) 
F-23

 
 
CHARAH SOLUTIONS, INC. 
Notes to Consolidated Financial Statements, continued

with the allocation of the purchase price for the acquisition finalized as of March 31, 2019 with the recognized goodwill allocated to the 
Consolidated Balance Sheets. In November 2018, the $15,000 to be paid over time was reduced by $3,300. 
As previously discussed and as further discussed in Note 10, during the year ended December 31, 2020, the Company evaluated the 
recoverability of certain grinding technology assets. As part of that review, we assessed the likelihood of paying the contingent liability based on 
achieving certain performance sales levels using these technology assets. The Company concluded that certain sales levels would not be 
achieved, and we reduced the corresponding liability by $9,702 and this reduction was recognized as a component of operating (loss) income in 
the Consolidated Statement of Operations. As of December 31, 2021, the remaining liability balance of $1,950 is expected to be paid after 2022. 
 
7. Asset Retirement Obligations 
The Company owns one structural fill site with continuing maintenance and monitoring requirements after its closure and four tracts of 
real property with decommissioning, remediation and monitoring requirements. As of December 31, 2021 and 2020, the Company has accrued 
$42,413 and $5,159, respectively, for the asset retirement obligations (“ARO”). 
Structural Fill Site ARO 
Asset retirement activities and our related accounting for this ARO are as follows: 
•Final capping and closure involve the installation of drainage and compacted soil layers and topsoil over areas where total airspace 
capacity has been consumed. Asset retirement obligations are recorded on a units-of-consumption basis as airspace is consumed. 
The liability is based on estimates of the discounted cash flows. 
•Post closure involves the maintenance and monitoring of the structural fill sites. Generally, we are required to maintain and monitor the 
structural fill sites for a 30-year period. These maintenance and monitoring costs are recorded as an asset retirement obligation as 
airspace is consumed over the life of the structural fill sites. Post-closure obligations are recorded over the life of the structural fill 
sites on a units-of-consumption basis as airspace is consumed, based on estimates of the discounted cash flows associated with 
performing post-closure activities. 
We develop our estimates of these obligations using input from our operations personnel. Our estimates are based on our interpretation 
of current requirements and proposed regulatory changes and are intended to approximate fair value. Absent quoted market prices, the estimate 
of fair value is based on the best available information, including the results of present value techniques. We use professional engineering 
judgment and estimated prices paid for similar work to determine the fair value of these obligations. We are required to recognize these 
obligations at market prices whether we plan to contract with third parties or perform the work ourselves. In those instances where we perform 
the work with internal resources, the incremental profit margin realized will be recognized as a component of operating income when the work is 
completed. 
Once we determined the final capping, closure, and post-closure costs, we inflated those costs to the expected time of payment and 
discount those expected future costs back to present value using an inflation rate of 3.0%. We discounted these costs to present value using the 
credit-adjusted, risk-free rate effective of 5.25% at the time an obligation was incurred, consistent with the expected cash flow approach. 
We record the estimated fair value of final capping, closure, and post-closure liabilities for our structural fill sites based on the capacity 
consumed through the current period. Because these obligations are measured at estimated fair value using present value techniques, changes 
in the estimated cost or timing of future final capping, closure, and post-closure activities could result in a material change in these liabilities, 
related assets, and results of operations. We assess the appropriateness of the estimates used to develop our recorded balances annually, or 
more often if conditions warrant. 
Real Estate AROs 
The Company acquired certain real property through the Gibbons Creek Transaction with decommissioning, remediation and monitoring 
requirements. Refer to Note 5, Asset Acquisition, for asset retirement activities and our related accounting for these AROs.

During the year ended December 31, 2021, the Company recognized a gain on ARO settlement of $3,623 representing differences 
between the estimated costs used in the measurement of the fair value of the Company's AROs and the actual expenditures incurred for specific 
remediation tasks performed during the year ended December 31, 2021. 
During the year ended December 31, 2020, after the expiration of the option and the impairment of the structural fill site assets in August 
2020 as discussed above, the Company performed a review of the asset retirement obligation to determine if there had been changes in the 
estimated amount or timing of cash flows. The Company identified a downward adjustment of $2,127 primarily due to the refinement of cost 
information associated with project bonding and insurance and the decrease in actual closure costs incurred since the site has ceased 
operations. The Company views the asset retirement obligation and the related structural fill site asset as a single asset so we first recorded a 
reduction of $279 to the carrying value of the asset and then recorded the excess balance of $1,848 as a reduction to cost of sales in the 
Consolidated Statement of Operations. 
 
8. Equity Method Investments 
In January 2016, Charah, LLC, a Delaware limited liability company and wholly-owned subsidiary of Charah Solutions, organized a joint 
venture with VHSC Holdings, LLC, an unrelated third party, to provide ash management and remarketing services to the electric utility industry. 
The Company owns a 50% interest in the joint venture and accounts for its investment under the equity method of accounting because we have 
significant influence over the financial and operating policies of the company. The Company had a receivable due from the equity method 
investment of $0 and $182 at December 31, 2021 and 2020, respectively. 
In December 2020, the Company informed our joint venture partner of our decision to exit the joint venture due to unfavorable economic 
conditions associated with a new contract that would adversely impact the future earnings capacity of our investment. As a result, the Company 
determined it was unlikely that it would recover the full carrying amount of the investments and recognized an impairment charge of $3,800 in the 
year ended December 31, 2020. In 2021, the joint venture sold its property and equipment at an amount exceeding carrying value and continues 
to settle its remaining current assets and liabilities through the normal course of business. 
The following table sets forth the summarized balance sheet information of our equity method investment entity as of:

9. Distributions to Stockholders, Receivable from Affiliates, and Related Party Transactions 
ATC Group Services LLC (“ATC”), an entity owned by BCP, our majority stockholder, provided environmental consulting and 
engineering services at certain service sites. Expenses to ATC were $100, $288, $184, during the years ended December 31, 2021, 2020, and 
2019. The Company had no receivables outstanding from ATC at December 31, 2021 and 2020. The Company had payables and accrued 
expenses, net of credit memos, due to ATC of $4 and $29 at December 31, 2021 and 2020, respectively. 
Brown & Root Industrial Services, LLC (“B&R”), an entity 50% owned by BCP, our majority stockholder, provided subcontracted 
construction services at one of our remediation and compliance service sites in 2019. Expenses to B&R were $1,565 during the year ended 
December 31, 2019. The Company had no receivables outstanding from or payables due to B&R at December 31, 2021 and 2020. 
The Company previously rented its corporate office through October 2019 through a triple net lease and rented housing at work sites 
and a condo through March 2020 from Price Real Estate, LLC (“Price Real Estate”), an entity owned by a stockholder of the Company. Rental 
expense associated with Price Real Estate of $391 was incurred during the year ended December 31, 2019, respectively. The Company had no 
receivables outstanding from or payables due to Price Real Estate at December 31, 2021 and 2020. 
PriceFlight, LLC (“PriceFlight”), an entity owned by a stockholder of the Company, previously provided flight services to the Company in 
2019. Expenses to PriceFlight for flight services amounted to $85 during the years ended December 31, 2019. The Company had no receivables 
outstanding from or payables due to PriceFlight at December 31, 2021 and 2020. 
Management determined that Price Real Estate and PriceFlight are variable interest entities. The Company has variable interests in 
them through the common ownership and contractual agreements discussed above. The Company is not considered to be the primary 
beneficiary. Management considers the likelihood to be remote that the Company will be required to make future funds available to Price Real 
Estate and PriceFlight. However, were the Company required to make funds available, the maximum exposure to the Company would be any 
excess of the debt obligations of Price Real Estate and PriceFlight over the fair value of their respective assets. 
As further discussed in Note 10, Long-term Debt, in August 2021, the Company completed an offering of $135,000, in the aggregate, of 
the Notes, which amount included the exercise by the underwriters of their option to purchase an additional $5,000 aggregate principal amount 
of Notes. B. Riley Securities, Inc. (“B. Riley”), a shareholder of the Company with board representation, served as the lead book-running 
manager and underwriter for this offering, purchasing a principal amount of $80,325 of the Notes. Fees paid to B. Riley related to this offering 
were $7,914 for the year ended December 31, 2021. These fees were capitalized as debt issuance costs within notes payable, less current 
maturities in the Consolidated Balance Sheets and will be amortized prospectively through interest expense, net in the Consolidated Statements 
of Operations using the effective interest method through the maturity date of the Notes. In addition, Charah, LLC, a Kentucky limited liability 
company and 
F-26

 
 
CHARAH SOLUTIONS, INC. 
Notes to Consolidated Financial Statements, continued 
(amounts in thousands except per share data) 
 
 
indirect subsidiary of the Company, issued a promissory note in exchange for cash in favor of B. Riley Commercial Capital, LLC, an affiliate of B. 
Riley, evidencing a loan in aggregate principal amount of $17,852. The promissory note was repaid in full as of December 31, 2021. 
As further discussed in Note 3, in November 2020, the Company sold its Allied subsidiary to an affiliate of BCP. 
As further discussed in Note 13, in March 2020, the Company entered into an agreement with an investment fund affiliated with BCP to 
sell 26,000 shares of Preferred Stock. 
 
10. Goodwill and Intangible Assets 
Goodwill and indefinite-lived intangible assets are not amortized but instead are tested for impairment annually or more often if events or 
changes in circumstances indicate that the fair value of the asset may have decreased below its carrying value. We perform our impairment test 
effective October 1st of each year and evaluate for impairment indicators between annual impairment tests. 
Goodwill 
As of December 31, 2021 and 2020, goodwill was $62,193. We performed a quantitative assessment of the Company, which we 
concluded was a single reporting unit, as of October 1, 2021 using a market approach, whereby the market capitalization of the Company was 
compared to its carrying value. The market capitalization was derived from the Company's publicly traded stock price. The fair value of the 
reporting unit exceeded its carrying value, and therefore, no impairment was recognized. 
Indefinite-Lived Intangible Asset 
Our intangible assets, net include a trade name that is considered to have an indefinite life. The Charah trade name fair value is based 
upon the income approach, primarily utilizing the relief-from-royalty methodology. This methodology assumes that, in lieu of ownership, a third 
party would be willing to pay a royalty in order to obtain the rights to use the comparable asset. An impairment loss is recognized when the 
estimated fair value of the intangible asset is less than the carrying value. The fair value calculation requires significant judgments in determining 
both the assets’ estimated cash flows as well as the appropriate discount and royalty rates applied to those cash flows to determine fair value. 
Variations in economic conditions or a change in general consumer demands, operating results estimates or the application of alternative 
assumptions could produce significantly different results. 
During the year ended December 31, 2020, we recorded an impairment of our Charah trade name intangible asset of $21,014, primarily 
as a result of a decrease in the royalty rate used in the valuation that was primarily attributable to the recent performance of the Company. 
Definite-Lived Intangible Assets 
Definite-lived intangible assets are comprised of our customer relationships. Amortization expense of definite-lived intangible assets was 
$7,894, $8,582, and $8,400 for the years ended December 31, 2021, 2020, and 2019, respectively. 
Long-lived assets, including definite-lived intangible assets are reviewed for impairment whenever certain triggering events may indicate 
impairment. There was no impairment of definite-lived intangible assets for the year ended December 31, 2021. 
During the year ended December 31, 2020, as discussed in Note 6, the Company determined that certain technology- related equipment 
and construction in progress assets were no longer viable and recognized an impairment charge associated with those assets. As a result of this 
impairment, we concluded that a triggering event had occurred that indicated that the technology intangible asset group may not be recoverable. 
We determined that the technology intangible asset had no value since we will no longer be attempting to use the technology in construction 
equipment. The Company recognized an impairment charge of $1,452.

11. Long-term Debt 
Senior Notes 
On August 25, 2021, the Company completed an offering of $135,000, in the aggregate, of the Company’s Notes, which amount 
includes the exercise by the underwriters of their option to purchase an additional $5,000 aggregate principal amount of Notes. 
The Notes were issued pursuant to the First Supplemental Indenture (the “First Supplemental Indenture”), dated as of August 25, 2021, 
between the Company and Wilmington Savings Fund Society, FSB, as trustee (the “Trustee”). The First Supplemental Indenture supplements 
the Indenture entered into by and between the Company and the Trustee, dated as of August 25, 2021 (the “Base Indenture” and, together with 
the First Supplemental Indenture, the “Indenture”). 
The public offering price of the Notes was 100.0% of the principal amount. The Company received proceeds before payment of 
expenses and other fees of $135,000. The Company used the proceeds, along with cash from the issuance of $13,000 of common stock, to fully 
repay and terminate the Company’s Credit Facility, as defined below. 
The Notes bear interest at the rate of 8.50% per annum. Interest on the Notes is payable quarterly in arrears on January 31, April 30, 
July 31 and October 31 of each year, commencing October 31, 2021. The Notes will mature on August 31, 2026. 
The Company may redeem the Notes for cash in whole or in part at any time (i) on or after August 31, 2023 and prior to August 31, 
2024, at a price equal to 103% of their principal amount, plus accrued and unpaid interest to, but excluding, the date of redemption, (ii) on or 
after August 31, 2024 and prior to August 31, 2025, at a price equal to 102% of their principal amount, plus accrued and unpaid interest to, but 
excluding, the date of redemption, and (iii) on or after August 31, 2025 and prior to maturity, at a price equal to 100% of their principal amount, 
plus accrued and unpaid interest to, but excluding, the date of redemption. On and after any redemption date, interest will cease to accrue on the 
redeemed Notes. 
The Indenture also contains customary event of default and cure provisions. If an uncured default occurs and is continuing, the Trustee 
or the holders of not less than 25% in aggregate principal amount of the Notes may declare the Notes to be immediately due and payable.

The Notes are senior unsecured obligations of the Company and rank equal in right of payment with the Company’s existing and future 
senior unsecured indebtedness. 
As a result of the issuance of the Notes, $12,116 of third-party fees were capitalized as debt issuance costs that will be amortized 
through interest expense, net in the Consolidated Statements of Operations using the effective interest method through the maturity date of the 
Notes. 
Asset-Based Lending Credit Agreement 
On November 9, 2021, the Company entered into a new Credit Agreement with JPMorgan Chase Bank, N.A. (“JPMorgan”), as 
administrative agent, the lenders party thereto and certain subsidiary guarantors named therein. The Credit Agreement provides for a four-year 
senior secured revolving credit facility with initial aggregate commitments from the lenders of $30,000, which includes $5,000 available for 
swingline loans, plus an additional $5,000 of capacity available for the issuance of letters of credit if supported by cash collateral provided by the 
Company (with a right to increase such amount by up to an additional $5,000) (“Aggregate Revolving Commitments”). Availability under the 
Credit Agreement is subject to a borrowing base calculated based on the value of certain eligible accounts receivable, inventory, and equipment 
of the Company and subject to redeterminations made in good faith and in the exercise of permitted discretion of JPMorgan. Proceeds of the 
Credit Agreements may be used for working capital and general corporate purposes. 
The Credit Agreement provides for borrowings of either base rate loans or Eurodollar loans. Principal amounts borrowed are payable on 
the maturity date with such borrowings bearing interest that is payable (i) with respect to base rate loans, monthly and (ii) with respect to 
Eurodollar loans, the last day of each Interest Period (as defined below); provided that if any Interest Period for a Eurodollar loan exceeds three 
months, interest will be payable on the respective dates that fall every three months after the beginning of such Interest Period. Eurodollar Loans 
bear interest at a rate per annum equal to the Adjusted LIBOR for one, three or six months (the “Interest Period”), plus an applicable margin of 
2.25%. Base rate loans bear interest at a rate per annum equal to the greatest of (i) the agent bank’s reference rate, (ii) the federal funds 
effective rate plus 50 basis points and (iii) the rate for one month Adjusted LIBOR loans plus 100 basis points, plus an applicable rate of 125 
basis points. The Credit Agreement contains a provision for sustainability adjustments annually that will impact the applicable margin by between 
positive 0.05% and negative 0.05% based on the achievement, or lack thereof, of certain metrics agreed upon between JPMorgan and the 
Company and publicly reported through the Company’s annual non-financial sustainability report. 
The Credit Agreement is guaranteed by certain of the Company’s subsidiaries and is secured by substantially all of the Company’s and 
such subsidiaries’ assets. The Credit Agreement contains customary restrictive covenants for asset-based loans that may limit the Company’s 
ability to, among other things: incur additional indebtedness, sell assets, make loans to others, make investments, enter into mergers, make 
certain restricted payments, incur liens, and engage in certain other transactions without the prior consent of the lenders. 
A covenant testing period (“Covenant Testing Period”) is a period in which excess availability (which is defined in the Credit Agreement 
as the sum of availability and an amount up to $1,000), is less than the greater of (a) 12.5% of the lesser of the aggregate revolving 
commitments and the borrowing base, (b) the lesser of $7,500 and the PP&E Component as defined in the Credit Agreement, and (c) $3,500, for 
three consecutive business days. During a Covenant Testing Period, the Credit Agreement requires the Company to maintain a fixed charge 
coverage ratio as defined in the Credit Agreement, determined for any period of twelve (12) consecutive months ending on the last day of each 
fiscal quarter, of at least 1.00 to 1.00. 
As of December 31, 2021, the Company has not drawn on the Credit Agreement. Outstanding letters of credit were $19,027 as of 
December 31, 2021. As of December 31, 2021, the Company had $13,387 of outstanding letters of credit with JPMorgan and $5,649 with Bank 
of America, N.A. 
As a result of entering into the Credit Agreement, $1,366 of third-party fees were capitalized as debt issuance costs that will be 
amortized through interest expense, net in the Consolidated Statements of Operations using the effective interest method through the maturity 
date of the Credit Agreement. 
Letter of Credit Cash Collateralization Promissory Note 
On August 25, 2021, Charah, LLC issued a Secured Promissory Note (the “Promissory Note”), as the borrower, in favor of B. Riley 
Commercial Capital, LLC, as the noteholder (the “Noteholder”), evidencing a loan in aggregate principal amount of $17,852 made by the 
Noteholder to Charah, LLC. The loan outstanding under the Promissory Note bears interest at a rate of eight percent (8%) per annum and was 
set to mature on the thirteen-month anniversary of the effective date of the 
 
F-29

 
 
CHARAH SOLUTIONS, INC. 
Notes to Consolidated Financial Statements, continued 
(amounts in thousands except per share data) 
 
 
Promissory Note. The proceeds of the Promissory Note were used by the Company and its subsidiaries to collateralize the Company's existing 
letters of credit issued through Bank of America, N.A. The loan was repaid in full during the year ended December 31, 2021. 
Previous Credit Facility 
On September 21, 2018, we entered into a credit agreement (the “Credit Facility”) by and among us, the lenders party thereto from time 
to time and Bank of America, N.A., as administrative agent (the “Administrative Agent”). The Credit Facility included: 
•A revolving loan not to exceed $50,000 (the “Revolving Loan”); 
•A term loan of $205,000 (the “Closing Date Term Loan”); and 
•A commitment to loan up to a further $25,000 in term loans, which expired in March 2020 (the “Delayed Draw Commitment” and the 
term loans funded under such Delayed Draw Commitment, the “Delayed Draw Term Loan,” together with the Closing Date Term 
Loan, the “Term Loan”). 
Pursuant to the terms of the Credit Facility and its related amendments, all amounts associated with the Revolving Loan and the Term 
Loan under the Credit Facility were set to mature in July 2022. The interest rates per annum applicable to the loans under the Credit Facility 
were based on a fluctuating rate of interest measured by reference to, at our election, either (i) the Eurodollar rate, currently LIBOR, or (ii) an 
alternative base rate. Various margins were added to the interest rate based upon our consolidated net leverage ratio (as defined in the Credit 
Facility). Customary fees were payable regarding the Credit Facility and included (i) commitment fees for the unused portions of the Credit 
Facility and (ii) fees on outstanding letters of credit. Amounts borrowed under the Credit Facility were secured by substantially all of the assets of 
the Company. 
The Credit Facility contained various customary representations, warranties, restrictive covenants, certain affirmative covenants, 
including reporting requirements, and customary events of default. 
Outstanding letters of credit under the previous Credit Facility were $11,079 as of December 31, 2020. 
During the year ended December 31, 2021, using the proceeds from the Notes, along with cash from the issuance of $13,000 of 
common stock, to fully repay and terminate the Credit Facility, the Company paid $114,123 of outstanding principal on the Closing Date Loan 
and $12,340 of outstanding loans on the Revolver. Further, the Company paid $2,000 of previously accrued fees required as consideration for 
Amendment No. 3 to Credit Agreement that was otherwise due and payable on the maturity date. During the year ended December 31, 2021, 
the Company wrote off unamortized debt issuance costs of $638 as a result of extinguishment of debt, which is included in loss on 
extinguishment of debt in the Consolidated Statements of Operations.

13. Sale-leaseback Transaction 
In November 2020, we entered into a sale-leaseback transaction whereby we sold and leased back plant, machinery and equipment and 
vehicles. The transaction met the requirements of a sale in accordance with ASC 606, and the lease is classified as a capital lease. Proceeds 
from the sale were $7,000, and the cost and related accumulated depreciation of the plant, machinery and equipment and vehicles of $9,841 
and $3,302, respectively, were removed from the Consolidated Balance Sheet at the time of the sale. The $461 gain realized on the sale and 
$88 in loan origination fees incurred at the time of the sale were included in the capital lease asset that will be depreciated over the life of the 
lease or three years. The lease obligation of $2,357 and $2,128 is recorded within current and long-term liabilities, respectively, in the 
Consolidated Balance Sheet as of December 31, 2021. The proceeds from the sale were recorded within investing activities in the Consolidated 
Cash Flow Statements. 
 
14. Mezzanine Equity 
In March 2020, the Company entered into an agreement with an investment fund affiliated with BCP to sell 26 (twenty-six thousand) 
shares of Series A Preferred Stock, par value $0.01 per share (the “Preferred Stock”), with an initial aggregate liquidation preference of $26,000, 
net of a 3% Original Issue Discount (“OID”) of $780 for net proceeds of $25,220 in a private placement (the “Preferred Stock Offering”). 
Proceeds from the Preferred Stock Offering will be used for liquidity and general corporate purposes. In connection with the issuance of the 
Preferred Stock, the Company incurred direct expenses of $966, including financial advisory fees, closing costs, legal expenses and other 
offering-related expenses. The Preferred Stock was initially recorded net of OID and direct expenses, which will be accreted through 
paid-in-capital as a deemed dividend from the date of issuance through the first possible known redemption date, March 16, 2023. As of 
December 31, 2021, the Company had accrued dividends of $1,030 associated with the Preferred Stock, which was recorded at a fair value of 
$1,994 using unobservable information for similar items and is classified as a level 3 fair value measurement. 
Dividend Rights The Preferred Stock ranks senior to the Company’s common stock with respect to dividend rights and rights on the 
distribution of assets in any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Company. The Preferred Stock had 
an initial liquidation preference of $1 (one thousand dollars) per share. 
The holders of the Preferred Stock are entitled to a cumulative dividend paid in cash at the rate of 10.0% per annum, payable on a 
quarterly basis. If we do not declare and pay a dividend to the holders of the Preferred Stock, the dividend rate will increase to 13.0% per annum 
and the dividends are paid-in-kind by adding such amount to the liquidation preference. Upon meeting certain "specified payment conditions," 
the Company has the ability under the Asset-Based Lending Credit Agreement to pay cash dividends on the Series A Preferred Stock. However, 
the Company’s intention is to pay dividends in-kind for the foreseeable future. The dividend rate will increase to 16.0% per annum upon the 
occurrence and during the continuance of an event of default. As of December 31, 2021, the liquidation preference of the Preferred Stock was 
$32,712. 
Conversion Features The Preferred Stock is convertible at the option of the holders at any time on and subsequent to the three-month 
anniversary of the date of issuance into shares of common stock at a conversion price of $2.77 per share (the “Conversion Price”), which 
represents a 30% premium to the 20-day volume-weighted average price ended March 4, 2020. As of December 31, 2021, the maximum 
number of common shares that could be required to be issued if converted is 11,809 (eleven million eight hundred nine thousand). The 
conversion rate is subject to the following customary anti-dilution and other adjustments: 
•the issuance of common stock as a dividend or the subdivision, combination, or reclassification of common stock into a greater or lesser 
number of shares of common stock; 
F-32

 
 
CHARAH SOLUTIONS, INC. 
Notes to Consolidated Financial Statements, continued 
(amounts in thousands except per share data) 
 
 
•the dividend, distribution or other issuance of rights, options or warrants to holders of common stock entitling them to subscribe for or 
purchase shares of common stock at a price per share that is less than the market value for such issuance; 
•the issuance of a dividend or similar distribution in-kind, which can include shares of any class of capital stock, evidences of the 
Company’s indebtedness, assets or other property or securities, to holders of common stock; 
•a transaction in which a subsidiary of the Company ceases to be a subsidiary of the Company as a result of the distribution of the equity 
interests of the subsidiary to the holders of the Company’s common stock; and 
•the payment of a cash dividend to the holders of common stock. 
On or subsequent to the three-year anniversary of the date of issuance, if the holders have not elected to convert all their shares of 
Preferred Stock, the Company may give 30 days’ notice to the holders giving the holders the option to choose, in their sole discretion, to have all 
outstanding shares of Preferred Stock converted into shares of common stock or redeemed in cash at the then applicable Redemption Price (as 
defined below). The Company may not issue this conversion notice unless (i) the average volume-weighted average price per share of the 
Company’s common stock during each of the 20 consecutive trading days before the conversion is greater than 120% of the conversion price; 
(ii) the Company’s common stock is listed on a national securities exchange; (iii) a registration statement for the re-sale of the common stock is 
then effective; and (iv) the Company is not then in possession of material non-public information as determined by Regulation FD promulgated 
under the Exchange Act. 
The Preferred Stock and the associated dividends during the year ended December 31, 2021 did not generate a beneficial conversion 
feature (“BCF”) upon issuance as the fair value of the Company’s common stock was less than the conversion price at the dividend dates. The 
Company will determine and, if required, measure a BCF based on the fair value of our stock price on the date dividends are declared for each 
subsequent dividend. If a BCF is recognized, a reduction to paid-in capital and the Preferred Stock will be recorded and then subsequently 
accreted through the first redemption date. 
Additionally, the Company determined that the nature of the Preferred Stock was more akin to an equity instrument and that the 
economic characteristics and risks of the embedded conversion options were clearly and closely related to the Preferred Stock. As such, the 
conversion options were not required to be bifurcated from the host under ASC 815, Derivatives and Hedging. 
Redemption Rights If the Company undergoes certain change of control transactions, the Company will be required to immediately make 
an offer to repurchase all of the then-outstanding shares of Preferred Stock for cash consideration per share equal to the greater of (i) 100% of 
the Liquidation Preference, plus accrued and unpaid dividends, if any, plus, if applicable for a transaction occurring before the third anniversary 
of the closing, a make-whole premium determined pursuant to a calculation of the present value of the dividends that would have accrued 
through such anniversary, discounted at a rate equal to the applicable treasury rate plus 0.50% (the “Make-Whole Premium”); provided that if the 
transaction occurs before the first anniversary of the closing, the Make-Whole Premium shall be no greater than $4,000 and (ii) the closing sale 
price of the common stock on the date of such redemption multiplied by the number of shares of common stock issuable upon conversion of the 
outstanding Preferred Stock. 
On or subsequent to the three-year anniversary of the issuance of the Preferred Stock, the Company may redeem the Preferred Stock, 
in whole or in part, for an amount in cash equal to the greater of (i) the closing sale price of the common stock on the date the Company delivers 
such notice multiplied by the number of shares of common stock issuable upon conversion of the outstanding Preferred Stock and (ii) (x) if the 
redemption occurs before the fourth anniversary of the date of the closing, 103% of the Liquidation Preference, plus accrued and unpaid 
dividends, or (y) if the redemption occurs on or after the fourth anniversary of the date of the closing, the Liquidation Preference plus accrued 
and unpaid dividends (the foregoing clauses (i) or (ii), as applicable, the “Redemption Price”). 
On or subsequent to the seven-year anniversary of the date of issuance, the holders have the right, subject to applicable law, to require 
the Company to redeem the Preferred Stock, in whole or in part, into cash consideration equal to the liquidation preference, plus all accrued and 
unpaid dividends, from any source of funds legally available for such purpose. 
Since the redemption of the Preferred Stock is contingently or optionally redeemable and therefore not certain to occur, the Preferred 
Stock is not required to be classified as a liability under ASC 480, Distinguishing Liabilities from Equity. As the Preferred Stock is redeemable in 
certain circumstances at the option of the holder and is redeemable in certain 
F-33

circumstances upon the occurrence of an event that is not solely within our control, we have classified the Preferred Stock in mezzanine equity 
in the Consolidated Balance Sheets. 
Liquidation Rights In the event of any liquidation, winding-up or dissolution of the Company, whether voluntary or involuntary, the holders 
of the Preferred Stock would receive an amount in cash equal to the greater of (i) 100% of the liquidation preference plus a Make-Whole 
Premium and (ii) the amount such holders would be entitled to receive at such time if the Preferred Stock were converted into Company common 
stock immediately before the liquidation event. The Make-Whole Premium is removed from the calculation for a liquidation event occurring 
subsequent to the third anniversary of the issuance date. 
Voting Rights The holders of the Preferred Stock are entitled to vote with the holders of the common stock on an as-converted basis in 
addition to voting as a separate class as provided by applicable Delaware law and the Company’s organizational documents. The holders, acting 
exclusively and as a separate class, shall have the right to appoint either a non-voting observer to the Company’s Board of Directors or one 
director to the Company’s Board of Directors. 
Registration Rights The holders of the Preferred Stock have certain customary registration rights with respect to the Preferred Stock and 
the shares of common stock into which they are converted, pursuant to the terms of a registration rights agreement. 
 
15. Interest Rate Swap 
The Company entered into an interest rate swap in December 2017 whereby the Company agreed to exchange with the counterparty, at 
specified intervals, the difference between fixed and variable interest amounts calculated by reference to a notional amount. On August 19, 
2021, the Company terminated the interest rate swap in conjunction with the termination of the Credit Facility and issuance of the Notes. In 
conjunction with the termination, the Company settled the outstanding liability that was previously classified within other liabilities in the 
Consolidated Balance Sheet by paying $745 to the counterparty, which represented the fair value of the swap as of the termination date. 
The total amount of gain (loss) included in interest expense, net in the Consolidated Statements of Operations for the years ended 
December 31, 2021, 2020 and 2019 was $190, $181 and $(2,007), respectively. 
 
16. Contract Assets and Liabilities

17. Stock-Based Compensation 
The Company adopted the Charah Solutions, Inc. 2018 Omnibus Incentive Plan (the “2018 Plan”), pursuant to which employees, 
consultants, and directors of the Company and its affiliates, including named executive officers, are eligible to receive awards. The 2018 Plan 
provides for the grant of stock options, stock appreciation rights, restricted stock, restricted stock units, bonus stock, dividend equivalents, other 
stock-based awards, substitute awards, annual incentive awards, and performance awards intended to align the interests of participants with 
those of Company's stockholders. The Company has reserved 3,007 shares of common stock for issuance under the 2018 Plan, and all future 
equity awards described above will be issued pursuant to the 2018 Plan. During the year ended December 31, 2021, the Company amended the 
2018 Plan to reserve an additional 2,000 shares of common stock, for a total of 5,007 shares of common stock reserved for issuance under the 
2018 Plan. 
Restricted share units (“RSUs”) 
During the years ended December 31, 2021, 2020 and 2019, the Company granted 501, 542 and 769, respectively, RSUs under the 
2018 Plan that have time-based vesting requirements. 
Of the RSUs granted during the year ended December 31, 2021, 3 vested immediately, 90 vest at the end of a one-year period, and 408 
vest in equal annual installments over three years. The fair value of these RSUs is based on the market price of the Company’s shares on the 
grant date. As of December 31, 2021, 3 of the shares were vested and none had been forfeited. 
Of the RSUs granted during the year ended December 31, 2020, 15 vest at the end of an eleven-month period, 90 vest at the end of a 
one-year period, and 437 vest in equal annual installments over three years. The fair value of these RSUs is based on the market price of the 
Company’s shares on the grant date. As of December 31, 2021, 251 of the shares were vested and 71 had been forfeited. 
Of the RSUs granted during the year ended December 31, 2019, 2 vested immediately, 128 vest after one year, 550 vest in equal 
installments over three years, and 89 vest in equal installments over four years. The fair value of these RSUs is based on the market price of the 
Company's shares on the grant date. As of December 31, 2021, 491 of the shares were vested and 111 had been forfeited. 
Performance share units (“PSUs”) 
During the year ended December 31, 2021 and 2020, the Company granted 235 and 228 PSUs, respectively , under the 2018 Plan that 
cliff vest after three years. The vesting of the PSUs is dependent upon the following performance goals during a specified period (the 
“Performance Period”): (i) the relative total stockholder return (“TSR”) percentile ranking of the Company as compared to the specified 
performance peer group and (ii) cumulative revenue. Each performance goal is weighted at 50% in 
F-35

 
 
CHARAH SOLUTIONS, INC. 
Notes to Consolidated Financial Statements, continued 
(amounts in thousands except per share data) 
 
 
determining the number of PSUs that become earned PSUs. The maximum number of earned PSUs for the Performance Period is 200% of the 
target number of PSUs. The total compensation cost we will recognize under the PSUs will be determined using the Monte Carlo valuation 
methodology, which factors in the value of the TSR market condition when determining the grant date fair value of the PSU. Compensation cost 
for each PSU is recognized during the Performance Period based on the probable achievement of the two performance criteria. The PSUs are 
converted into shares of our common stock at the time the PSU award value is finalized. As of December 31, 2021, none of the shares granted 
during 2021 were vested or had been forfeited. As of December 31, 2021, none of the shares granted during 2020 were vested and 43 had been 
forfeited. 
During the year ended December 31, 2019, we also granted 331 performance share units (“PSUs”) under the 2018 Plan that cliff vest 
after three years. The vesting of these PSUs is dependent upon the Company’s achievement of certain stock price metrics. The fair value of the 
PSUs was determined using a binomial lattice model based upon the grant date stock price, a risk-free interest rate of 2.29% based upon the 
U.S. Treasury yield curve in effect at the time of the grants, and an assumed volatility rate of 30% based upon a comparable public company 
analysis. As of December 31, 2021, none of the shares were vested and 72 had been forfeited.

non-vested awards of restricted stock, net of estimated forfeitures, was $1,512, and is expected to be recognized over a weighted-average 
period of 1.29 years. The total fair value of awards vested for the year ended December 31, 2021 was $2,463. 
Stock-based compensation expense related to the performance stock issued was $757, $555, and $345 during the years ended

non-vested awards of performance stock, net of estimated forfeitures, was $968, and is expected to be recognized over a weighted-average 
period of 1.91 years. 
 
18. Defined Contribution Retirement Plan 
Charah and its operating subsidiary, Ash Management Services (“AMS”), provide a defined contribution employee benefit plan (the 
“Charah and AMS 401(k) Plan”) qualified under Section 401(k) of the Code to employees who have completed 90 days of service and have 
attained age 18. Participants may contribute up to the lesser of 90% of eligible compensation or the maximum allowed under the Code. Charah 
and AMS make safe harbor contributions to participant accounts equal to 3% of the participant’s annual compensation, commencing the quarter 
after the employee completes one year of service. Charah and AMS may also make discretionary contributions, and the contributions may vary 
from year to year for employees who have met one year of employment. Participants are immediately vested in their elective contributions and 
safe harbor contributions. Participants are vested in discretionary contributions after completing six years of service. During the year 
F-36

ended December 31, 2021, 2020 and 2019, Charah and AMS contributed $940, $393 and $1,014, respectively, to the Charah and AMS 
401(k) Plan. 
 
19. Commitments and Contingencies 
We were party to a lawsuit filed against North Carolina by an environmental advocacy group alleging that the issuance by the state of 
certain permits associated with our Brickhaven clay mine reclamation site exceeded the state’s power. In December 2020, the Company, the 
environmental advocacy group and the state settled, resolved and dismissed all matters. Before the settlement, all customer-related work at the 
Brickhaven site had been completed. The settlement allows for all completed work to remain unchanged. Per the settlement, the Company will 
not place any additional material at the site, will place a deed restriction requiring engineering oversight for the future development of the site 
and will continue groundwater monitoring at the site. In April 2021, the state approved the Company’s application to modify its permit to conform 
to the work as completed. The Company will continue its work with the state to complete the remaining site closure operations. 
Allied Power Services, LLC and its affiliate, Allied Power Resources, LLC, were named in a collective action lawsuit filed in the U.S. 
District Court for the Northern District of Illinois, alleging violations of the Fair Labor Standards Act. This lawsuit included related class claims 
alleging violations of the Illinois Minimum Wage Law and the Pennsylvania Minimum Wage Act for failure to pay overtime. This case was one of 
a series filed against companies in the oil, gas and energy industries in Illinois and Texas. The parties mediated this case in November 2018 and 
reached a settlement. As part of the Allied Transaction, the Company assumed the remaining settlement liability. On July 15, 2020, the court 
granted final approval of the settlement, and the final settlement payment was made in April 2021. 
In addition to the above matters, we are from time to time party to various lawsuits, claims and other legal proceedings that arise in the 
ordinary course of our business. For all such lawsuits, claims and proceedings, we record reserves when it is probable a liability has been 
incurred and the amount of loss can be reasonably estimated. Although it is difficult to predict the ultimate outcome of these lawsuits, claims and 
proceedings, we do not believe that the ultimate disposition of any of these matters, individually or in the aggregate, would have a material 
adverse effect on our results of operations, financial position or cash flows. We maintain liability insurance for certain risks that is subject to 
certain self-insurance limits. 
We believe amounts previously recorded are sufficient to cover any liabilities arising from the proceedings with all outstanding legal 
claims. Except as reflected in such accruals, we are currently unable to estimate a range of reasonably possible loss or a range of reasonably 
possible loss in excess of the amount accrued for outstanding legal matters. 
 
20. Multiemployer Pension Plan 
AMS contributes to union-sponsored multiemployer retirement defined benefit pension plans (the “multiemployer plans”) under the terms 
of collective bargaining agreements that cover its union-represented employees. The risks of participating in multiemployer plans are different 
from single-employer plans in the following aspects:  
•Assets contributed to the multiemployer plans by one employer may be used to provide benefits to employees of other participating 
employers. 
•If a participating employer stops contributing to the multiemployer plans, the unfunded obligations of the multiemployer plans may be 
borne by the remaining participating employers. 
•If AMS chooses to stop participating in the multiemployer plans, AMS may be required to pay the multiemployer plans an amount based 
on the underfunded status of the multiemployer plans, referred to as a withdrawal liability. 
The primary multiemployer plan to which AMS made contributions for the year ended December 31, 2021, 2020 and 2019 is outlined in 
the table below. The “EIN/Pension Plan Number” column provides the Employer Identification Number (“EIN”). The most recent Pension 
Protection Act zone status available in 2021 is for the respective multiemployer plan’s year-end within those years, unless otherwise noted. The 
zone status is based on information that AMS received from the multiemployer plans and is certified by the respective multiemployer plan’s 
actuary. Among other factors, multiemployer plans in the red zone (critical) are generally less than 65% funded, multiemployer plans in the 
yellow zone (endangered) are less than 80% funded, and multiemployer plans in the green zone (neither critical and declining, critical, or 
endangered) are at least 80% funded. The “FIP/RP Status Pending/Implemented” column indicates multiemployer plans for which a financial 
improvement plan (“FIP”) or a rehabilitation plan (“RP”) is either pending or has been implemented. The last column lists the expiration dates of 
the collective bargaining agreements to which the multiemployer plans are subject.

21. Income Taxes 
The Company is a “C” Corporation under the Code and, as a result, is subject to U.S. federal, state, and local income taxes. The 
Company’s subsidiaries previously operated as partnerships for income tax purposes. Before the contribution of assets and liabilities to the 
Company on June 18, 2018, the subsidiaries passed through their taxable income to their owners for U.S. federal and other state and local 
income tax purposes and, thus, the subsidiaries were not subject to U.S. federal income taxes or other state or local income taxes, except for 
franchise tax at the state level. 
The total income tax (benefit) expense on (loss) income before income taxes was allocated as follows:

The Company accounts for income taxes in accordance with ASC 740, which requires an asset and liability approach for measuring 
deferred taxes based on temporary differences between the financial statement and tax basis of assets and liabilities existing at each balance 
sheet date using enacted tax rates for the years in which taxes are expected to be paid or recovered. 
The components of the Company’s deferred tax assets and liabilities as of December 31, 2021 and 2020 are as follows:

The Company has net operating loss carryforwards of approximately $47,324 for federal income tax purposes as of December 31, 2021. 
The increase in the net operating loss carryforward from 2020 is primarily due to bonus depreciation. Additionally, capital losses recognized in 
2021 will be carried back to increase the net operating loss carryforward. Deferred interest expense carried forward to 2022 is approximately 
$9,900. Net operating losses have unlimited carryover periods. Net operating losses and deferred interest expense for state tax purposes vary 
by state due mainly to apportionment. Most states allow net operating loss carryovers for a limited number of years. 
Net deferred tax liabilities were $949 and $368 at December 31, 2021 and 2020, respectively. We consider both positive and negative 
evidence when measuring the need for a valuation allowance. The weight given to the evidence is commensurate with the extent to which it may 
be objectively verified. Current and cumulative financial reporting results are a source of objectively verifiable evidence. Operating results during 
the most recent three-year period receive a significant weight in our analysis. We typically only consider forecasts of future profitability when 
positive cumulative operating results exist in the most recent three-year period. We perform scheduling exercises to determine if sufficient 
taxable income of the appropriate 
F-39

(amounts in thousands except per share data) 
 
 
character exists in the periods required in order to realize our deferred tax assets with limited lives before their expiration. Realization of net 
operating losses and other carryforwards is dependent upon generating sufficient taxable income in the appropriate jurisdiction before the 
expiration of the carryforward periods, which involves business plans, planning opportunities and expectations about future outcomes. 
Furthermore, we consider tax planning strategies available to accelerate taxable amounts if required to utilize expiring deferred tax 
assets. A valuation allowance is not required to the extent that, in our judgment, positive evidence exists with a magnitude and duration sufficient 
to result in a conclusion that it is more likely than not that our deferred tax assets will be realized. A valuation allowance is recorded if it is more 
likely than not that a portion of our deferred tax assets will not be realized. 
The change in the valuation allowance for deferred tax assets is as follows: 
 
As of December 31, 
2021 
2020 
Beginning balance 
$ 
(17,158)  $ 
(12,908)

Other adjustments 
(908)  
 
6,690   
Ending balance 
$ 
(19,937)  $ 
(17,158)  
Based on the available evidence as of December 31, 2021 and 2020 we were not able to conclude it was more likely than not certain 
deferred tax assets would be realized. Therefore, a valuation allowance of $19,937 and $17,158 was recorded respectively, against our deferred 
tax assets. We will continue to evaluate the need for a valuation allowance on our deferred tax assets in future periods. 
The Company classifies any interest and penalties related to income taxes assessed as part of income tax expense. The Company has 
concluded that there are no significant uncertain tax positions requiring recognition in the financial statements, nor has the Company been 
assessed any significant interest or penalties by any major tax jurisdiction to any open tax periods. 
The Company’s income tax returns for the year ended December 31, 2020, 2019 and 2018 have been timely filed with the U.S. federal, 
state and local governments. The statute of limitations is open for the federal income tax return and certain state returns through October 15, 
2024, 2023, and 2022 respectively, and for most of the remaining state returns through October 15, 2025, 2024 and 2023, respectively. The 
examination of prior period tax returns filed for partnerships, the interests of which were contributed to the Company in the reorganization, could 
impact the Company’s tax expense and balance sheet tax accounts. 
The Company has a foreign subsidiary located in a foreign jurisdiction, for which 2020 and prior calendar years are open for examination 
by local tax authorities. The Company is not aware of any potential adjustments for 2020 or prior years and any potential adjustment is not 
expected to be material to the financial statements. 
 
22. Leases 
Operating leases 
The Company leases buildings, vehicles and equipment under various non-cancellable agreements classified as operating leases, which 
expire through December 2026 and require various minimum annual rentals.

23. Loss Per Share 
Basic loss per share is computed by dividing loss attributable to the Company’s stockholders by the weighted average number of shares 
outstanding during the period. Diluted loss per share reflects all potential dilutive ordinary shares outstanding during the period and is computed 
by dividing loss available to the Company’s stockholders by the weighted average number of shares outstanding during the period increased by 
the number of additional shares that would have been outstanding as dilutive securities.

The holders of the Preferred Stock have non-forfeitable rights to common stock dividends or common stock dividend equivalents. 
Accordingly, the Preferred Stock qualifies as participating securities. 
As a result of the net loss from continuing operations per share for the years ended December 31, 2021, 2020, and 2019, the inclusion 
of all potentially dilutive shares would be anti-dilutive. Therefore, dilutive shares (in thousands) of 12,234, 9,250, and 1,329 were excluded from 
the computation of the weighted average shares for diluted net loss per share for the years ended December 31, 2021, 2020, and 2019 
respectively.
