Dear Fellow Shareholders, 

The past year brought significant changes to our company and to our business as we reached the expiration date of our Refined Coal 
segment and achieved a record year for our APT segment since we acquired those assets in 2018.  

Throughout 2021, investors were able to better understand and envision the nature of our business after the end of the Refined Coal 
segment and we were able to further demonstrate the value of our APT segment’s assets. I’d like to thank all of our shareholders for 
their continued support throughout this process, and to express my gratitude to our team members for their tireless efforts in 2021. 

2021: Seizing Opportunities 

The end of 2021 marked the end of an era for Advanced Emissions Solutions, as our remaining invested Refined Coal facilities 
reached the end of their tax credit generation period. We expect a final $4.0-5.0 million of net, after-tax cash flows from the RC 
segment during the first half of 2022 as Tinuum winds down the business. As of this time, we have received our final royalty payment 
from Tinuum and we do not expect that the RC tax credit generation period will be extended. As utilities seek alternative combinations 
of products to meet their requisite emissions control standards, we envision an opportunity to convert these customers to our front-end 
chemical and/or activated carbon treatment technologies. Many of these utilities have already begun to purchase one of or even a 
combination of our products, which will help drive incremental revenue and margin within our APT segment on a go-forward basis.  

2021 also marked a momentous year for our APT segment and a clear inflection point for the profitability of the business. When we 
purchased ADA Carbon Solutions in late 2018, we knew that we had acquired the premier activated carbon manufacturing asset in 
North America. The Red River plant is a highly automated, non-union and an impressively efficient operation. The plant contains over 
6,000 points of automation and is uniquely designed to be power independent with the capability to sell excess power back to the grid. 
The sophisticated nature of the plant offers us an incredible opportunity to produce low-cost products and become the provider of 
choice for many activated carbon technologies in North America. We also own the nearby Natchitoches processing facility as well as a 
topsoil lignite mine that continues to provide a steady and consistent supply of feedstock for the plant. With these assets strategically 
located near a rail transportation hub, the vertically integrated nature of our assets provides a distinct competitive advantage.  

However, we also knew in 2018 that the near-term operating environment for activated carbon technologies – particularly for the coal-
fired power generation market – would be challenged. Power market conditions and the subsequent lower demand for our activated 
carbon products coupled with the suboptimal plant utilization rate prevented us from immediately achieving the financial performance 
that the segment is capable of. We navigated through a difficult 2019 and 2020 which challenged markets and economies around the 
world with the onset of the COVID-19 pandemic.

In response, we focused on what we could control. With 
confidence that industry conditions would eventually turn more 
favorable, we made important steps toward securing incremental 
contracted volume through competitive bid processes in a more 
diverse set of end-markets as well as strategically important 
supply agreements with Cabot. We diversified into adjacent 
market applications for activated carbon technologies to offset 
expected future Power Generation market declines.  

These adjacent markets included municipal water purification 
and industrial applications, both of which are smaller, but 
strategically important end-markets that diversify our product 
mix, expand the range of end-markets we serve, and de-risk our 
business. Today, we possess a much more diversified 
commercial end-market mix after considerable time and effort 
growing and expanding our commercial and technical 
relationships and conducting product tests with new potential 
customers in these expanded markets to capitalize on current 
and future opportunities.  

 
 
 
 
 
 
 
 
 
 
 
 
Additionally, we completed our Master Supply Agreement with Norit Activated Carbon (Norit) (f/k/a Cabot Norit Americas) in September 
of 2020. As a result of these initiatives, our end market mix today is greatly diversified compared to when we acquired ADA Carbon 
Solutions – which at the time was almost entirely dependent on the Power Generation market. We have emerged from difficult industry 
conditions in a much better position than most other producers. 

The APT segment has also been helped by the increase in volumes from our Power Generation customers as high prices for 
alternative energy sources such as natural gas has led to an increase in demand for our activated carbon products. The end result is 
that 2021 was a record revenue and production year for the APT segment. Revenue in the segment for the full year totaled $85.9 
million compared to $53.9 million in 2020, while APT segment operating income increased to $5.6 million compared to a $40.0 million 
loss in 2020.  

Despite the significant improvements, our margins in the segment remain pressured by our need to supplement inventory from external 
sources in order to meet high levels of customer demand. Our procurement of this outside inventory is creating a higher cost per unit, 
and we expect those conditions to persist well into 2022. In addition, the challenges created by general supply-chain bottlenecks and 
materials price inflation have impacted our business as well. During 2021 and into 2022, we have seen success in our effort to help 
offset these cost pressures through our ability to realign product pricing and overall contractual terms to better reflect current industry 
market conditions as contracts are renewed and new customers are acquired. 

Nonetheless, it is clear that we are making critically important strides toward realizing the full potential of the APT segment and its 
assets. The underlying momentum in the business throughout 2021 has remained robust and the segment’s overall performance is 
much improved when compared prior years. We’ve utilized our strong footing to explore options available to us to maximize 
shareholder value and, as a result, launched our strategic review process in May 2021. We look forward to announcing its resolution as 
we seek to take the next step toward ensuring our place as the provider-of-choice for activated carbon technologies in North America.   

2022: Driving Returns 

As the world transitions to a cleaner, more sustainable future, the need for new emissions control solutions for a growing suite of 
applications will become increasingly important. We expect to play a crucial role in this changing world, supported by the premier 
quality of our asset base and our extensive technological and commercial capabilities.  

We have already established our position as the industry leader for mercury control powder activated carbon (PAC) in North America 
and have also made important progress within the Water purification and Industrial markets. As has been well-documented over the 
years, clean water is increasingly in demand, both here and around the globe. We expect the application of activated carbon treatment 
solutions to continue to grow in the years to come.  

We also continue to leverage our industry-leading Technology team, utilizing 
their talents to drive growth across premium channels. Our ability to develop 
premium products that allow our customers to meet challenging regulations 
and operating conditions will foster deeper, more collaborative relationships 
that help drive customer loyalty. Ultimately, these relationships and continued 
R&D breakthroughs will lead to new product innovations that command 
premium margins or address new and evolving needs for solutions. 
Throughout 2021, our team worked closely with an industry leading channel 
partner within the growing soil and groundwater remediation market. Through 
this partnership, our team has succeeded in developing new activated carbon 
technologies which we believe will allow us to differentiate our market 
participation and further diversify the business.  

“As the world transitions to a 
cleaner, more sustainable 
future, the need for new 
emissions control solutions for a 
growing suite of applications will 
become increasingly important.” 

As the world’s need for sophisticated emissions control solutions and purification options grows, we expect to be a leading provider-of-
choice for these technologies, given our expertise and the quality and scale of our Red River plant. We believe our strong financial 
position and assets leave us well-positioned to pursue and develop additional and exciting opportunities. 

5 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
We are focused on two core priorities for 2022:  

•  Our first priority is to further enhance the long-term profitability of our APT segment. We will do this through continuing to 

capitalize on our world class manufacturing facilities through high utilization rates and optimizing the product mix, to further 
enhance the long-term profitability of our APT segment. Additionally, we will work to enhance our customer mix and 
structurally upgrade our customer contract terms. This will involve ongoing improvement to pricing as well as expanding 
volume commitments and protections which will allow us to offset headwinds we may encounter related to building back 
inventory and overall supply chain challenges. Aside from our historical core focuses within activated carbon markets we have 
served, we will also work to build upon the progress we made in 2021 and look to further diversify product and customer mix 
through ongoing investment in new product development. Lastly, we will remain vigilant for additional rationalization 
opportunities and supply agreements to increase market share. 

•  Our second priority is to allocate our cash flows and assets to drive shareholder value. We will continue to invest in the APT 

segment’s strategic initiatives, and we will work to conclude our strategic alternatives review in such a manner that maximizes 
shareholder value. 

I would like to again thank all of our shareholders for their continued support, as well as our team members for their selfless 
commitment to the Company over the past year. We have a bright future ahead of us and are well-positioned to capture opportunities 
that present themselves in a world increasingly focused on domestic sourcing and clean solutions. We look forward to serving you for 
another year and to sharing our future success with you.

General

PART I

ADA-ES, Inc. ("ADA"), a Colorado corporation, was incorporated in 1997. Pursuant to an Agreement and Plan of Merger, 
effective July 1, 2013, Advanced Emissions Solutions, Inc. ("ADES"), a Delaware company incorporated in 2011, succeeded 
ADA as the publicly-held corporation and ADA became a wholly-owned subsidiary of ADES. In 2018, we acquired ADA 
Carbon Solutions, LLC ("Carbon Solutions") as a means to enter into the broader activated carbon ("AC") market and to 
expand our product offerings in the mercury control industry and other applicable activated carbon markets. This Annual 
Report on Form 10-K is referred to as the "Form 10-K" or the "Report." As used in this Report, the terms the "Company," "we," 
"us" and "our" means ADES and its consolidated subsidiaries. 

We sell consumable products that utilize AC and chemical-based technologies to a broad range of customers, including coal-
fired utilities, industrials, water treatment plants and other diverse markets. Our proprietary technologies and associated product 
offerings provide purification solutions to enable our customers to reduce certain contaminants and pollutants to meet the 
challenges of existing and potential future regulations.

As of December 31, 2021 and 2020, we held equity interests of 42.5% and 50.0% in Tinuum Group, LLC ("Tinuum Group") 
and Tinuum Services, LLC ("Tinuum Services"), respectively, which are both unconsolidated entities, and historically have 
both contributed significantly to our financial position and results of operations. We account for Tinuum Group and Tinuum 
Services under the equity method of accounting. As a result of the expiration of Internal Revenue Code ("IRC") Section 45 - 
Production Tax Credit ("Section 45") refined coal tax credit program effective December 31, 2021, both Tinuum Group and 
Tinuum Services have substantially ceased operations as of December 31, 2021, and Tinuum Group is in the process of 
completing reclamation activities. See further discussion below under "Segments - RC" of this item. 

Markets

AC is a specialized sorbent material that is used widely in a host of industrial and consumer applications to remove impurities, 
contaminants and pollutants from gas, water and other product or waste streams. AC is produced by activating carbonaceous 
raw materials, including wood, coal, nut shells, resins and petroleum pitch. Properties such as surface area, pore volume, 
surface chemical functionalities and particle size can be specifically engineered to selectively target various contaminants to 
meet end-use application requirements. AC can come in several different forms that are important for the end-use application, 
including powdered activated carbon ("PAC"), granular activated carbon ("GAC"), pellets, honeycombs, blocks or cloths.  

Key markets include removal of pollutants from coal-fired electrical generation and other industrial processes, treatment of 
drinking and waste waters, industrial acid gas and odor removal, automotive gasoline emission control, soil and ground water 
remediation and food and beverage process and product purification.  

Demand for AC products has been, and is expected to continue to be, driven by increasing environmental regulations pertaining 
to water and air purification, especially in the developed and more industrialized areas of the world. Additionally, we believe 
environmental issues will continue to drive demand for AC in rapidly developing countries.

4

We see opportunities and are continuing to pursue diverse markets for our purification products outside of coal-fired power 
generation, including industrial applications, water treatment plants and other end markets. In addition, we see significant 
opportunities emerging in the soil, sediment and groundwater treatment markets. Increased environmental attention has been 
drawn to the monitoring and treatment of heavy metals, organic and inorganic compounds in groundwater to improve overall 
drinking water quality across North America. Activated carbon, in various forms, has and will continue to play a key role in 
these remediation efforts.

Segments

Advanced Purification Technologies

In our Advanced Purification Technologies ("APT") segment, our AC and chemical products are used to purify contaminated 
liquid and gas streams from a variety of industrial sources including coal-fired power plants and waste-water treatment plants, 
among others. Most of the North American coal-fired power generators installed equipment to control air pollutants, such as 
mercury, prior to or since the inception of the Mercury and Air Toxics Standards ("MATS"). However, many power generators 
need consumable products to complement the operation of installed equipment on a recurring basis to chemically and physically 
capture mercury and other contaminants. AC has been adopted as the most widely-used technology to capture mercury due to 
product efficiency and effectiveness and currently accounts for the majority of the mercury control consumables in the North 
American market. We offer AC and other chemical products and work with customers as they develop and implement a 
compliance control strategy that utilizes the consumables solutions that fit with their unique operating and pollution control 
configuration. 

For the purification of water, AC has been used in the treatment of drinking water, wastewater, contaminated soil and 
groundwater to adsorb compounds causing unpleasant taste and odor and other contaminants. Both industrial and municipal 
wastewater treatment plants have deployed the use of AC in their treatment processes. Groundwater contamination has become 
a matter of increasing concern to federal and state governments as well as to the public, especially over recent years. The U.S. 
AC market may see significant growth from water purification markets, especially if future regulations are passed controlling 
certain chemicals in drinking water. At present, individual states are primarily responsible for the protection of groundwater. 
The existing technologies for treatment, including removal of the soil for external treatment or landfill, pumping the 
groundwater above surface for treatment and/or installing treatment trenches or barriers, are expensive and may have 
complicated life-cycle management requirements. An emerging technology generating increasing interest by site engineering 
firms and owners is injecting highly engineered ACs into the subsoil, also described as "in situ" treatment, to intercept the 
contamination plume or to treat the groundwater. In response to this market opportunity, in late 2021, we developed a new 
Colloidal Carbon Product ("CCP") platform, FluxSorb ISTM, that is currently in the process of or planning stages of in-field 
testing at multiple contaminated soil and groundwater remediation treatment sites. 

Coal-fired power plants continue to be a significant, though declining, source of electricity in the United States. Demand for our 
AC products related to coal-fired electricity generation is dependent on the availability and cost of alternative energy sources, 
such as natural gas, solar and wind energy. We see opportunities to continue pursuing diverse markets for our purification 
products outside of coal-fired power generation, including industrial applications, water treatment plants and other markets. We 
believe the Supply Agreement with Cabot, as discussed below, will drive adoption of our AC products by customers in some of 
those diverse end-markets. 

Sales and Customers

Sales of consumables are primarily made by the Company’s employees to a range of end customers, including coal-fired 
utilities, industrial companies, water treatment plants and other customers. Our AC sales are generally made under 
requirements-based contracts ranging from one to five years. Our chemical product sales are generally made on a purchase 
order by purchase order basis. Revenues from our top three customers comprised approximately 37% of our consolidated 
consumables revenues for the year ended December 31, 2021, and the loss of any of these customers would have a material 
adverse effect on our operating results.

Cabot Supply Agreement and Related Agreements

On September 30, 2020, we and Cabot Norit Americas, Inc., ("Cabot") entered into a supply agreement (the "Supply 
Agreement") pursuant to which we agreed to sell and deliver to Cabot, and Cabot agreed to purchase and accept from us, 
certain lignite-based activated carbon products ("Furnace Products"). The term of the Supply Agreement is for 15 years with 
10-year renewal terms that are automatic unless either party provides three years prior notice of intention not to renew before 
the end of any term.

We believe the Supply Agreement will continue to provide material incremental sales volume and lower fixed operating costs 
on a per unit basis for our manufacturing plant located in Louisiana (the "Red River Plant"). Further, the Supply Agreement has 
expanded distribution of our AC products to additional markets outside of those we have traditionally served.

As a condition to entering into the Supply Agreement, on September 30, 2020, we entered into an agreement to purchase (the 
"Mine Purchase Agreement") from Cabot 100% of the membership interests in Marshall Mine, LLC (the "Marshall Mine 
Acquisition"), which owns a lignite mine located outside of Marshall, Texas (the "Marshall Mine"), for a nominal cash 
purchase price. Immediately after completion of the Mine Purchase Agreement, we independently determined to commence 
activities to shutter the Marshall Mine, and we will incur the associated reclamation costs as further described below.

In conjunction with the execution of the Supply Agreement and the Mine Purchase Agreement, on September 30, 2020, we 
entered into a reclamation contract (the "Reclamation Contract") with a third party that provides a capped cost, subject to 
certain contingencies, in the initial amount of approximately $19.7 million plus an obligation to pay certain direct costs of 
approximately $3.6 million (collectively, the "Reclamation Costs") over the estimated reclamation period of 10 years. Under the 
terms of the Supply Agreement, Cabot is obligated to reimburse us for approximately $10.2 million of the Reclamation Costs 
(the "Reclamation Reimbursements"), which are payable semi-annually over 13 years and inclusive of interest. 

As the owner of the Marshall Mine, we were required to post a surety bond to ensure performance of our reclamation activities 
under the Surety Bond Indemnification Agreement (the "Surety Agreement"). As of December 31, 2021, we posted a surety 
bond of $16.6 million. 

On February 1, 2021, we and a subsidiary of Cabot Corporation, Cabot Norit Nederland B.V. ("Cabot Corporation") entered 
into a five-year supply agreement ("EMEA Supply Agreement") to supply Cabot Corporation with lignite activated carbon 
products and other proprietary products used for mercury removal in utility and industrial coal-fired power plants in the EMEA 
market (as defined below). Cabot Corporation will be the exclusive and sole reseller of these products within Europe, Turkey, 
the Middle East and Africa ("EMEA"), and we will have a first right to provide the products to Cabot for sale in the EMEA 
market.

Competition

Our primary competitors for consumable sorbent products include Cabot (CBT), Calgon Carbon, a subsidiary of Tokyo Stock 
Exchange listed Kuraray Co., Ltd., Donau Carbon Company, Midwest Energy Emissions Corp. (MEEC) and Nalco Holding 
Company, a subsidiary of Ecolab Inc. (ECL).

Raw Materials

The principal raw material we use in the manufacturing of AC is lignite coal, which is readily available. We supply 100% of the 
lignite coal through our ownership of the Five Forks Mine ("Five Forks") to fulfill customer orders. Five Forks is operated for 
us by Demery Resources Company, LLC ("Demery"), a subsidiary of the North American Coal Company. We may also 
periodically purchase various ACs to supplement our inventory levels or to produce various products to serve AC certain 
markets.

We purchase various additives utilized in the production of AC. The manufacturing of AC is dependent upon these various 
additives that are subject to price fluctuations and supply constraints. In addition, the number of suppliers who provide the 
necessary additives needed to manufacture our ACs is limited. We purchase these additives through supply agreements or spot 
purchases with the producers. Supply agreements with these producers are generally renewed on an annual basis.

We also purchase additives that are included in certain chemical products for resale to our customers through contracts with 
suppliers. The manufacturing of these consumable products is dependent upon certain discrete additives that are subject to price 
fluctuations and supply constraints. In addition, the number of suppliers who provide the necessary additives needed to 
manufacture our chemical products are limited. Supply agreements with these producers are generally renewed on an annual 
basis.

Operations

We own and operate the Red River plant which is located in Louisiana. We also lease land in which operate a manufacturing 
and distribution facility located in Louisiana. Additionally, we have sales, product development and administrative operations 
located in Colorado. 

Refined Coal ("RC")

Through December 31, 2021, Tinuum Group provided reduction of mercury and nitrogen oxide ("NOX") emissions at select 
coal-fired power generators through the production and sale of RC that qualified for Section 45 tax credits. We benefited from 
Tinuum Group's production and sale of RC from our share of earnings from Tinuum Group's sales or leases of RC facilities to 
tax equity investors. As noted above, the Section 45 tax credit period expired on December 31, 2021 and both Tinuum Group 
and Tinuum Services substantially ceased operations as of that date. Tinuum Group is performing reclamation at its RC 
facilities and, along with Tinuum Services. As such, our earnings and distributions from our RC segment substantially ceased as 
of December 31, 2021, and this will have a material adverse effect on our results of operations and financial position beginning 
in 2022. See the separately filed financial statements of Tinuum Group included in Item 15 - "Exhibits, Financial Statement 
Schedules" ("Item 15") of this Report.

Products

Our patented M-45TM and M-45-PCTM technologies (collectively, the "M-45 Technology") are proprietary pre-combustion coal 
treatment technologies used to control emissions of nitrogen oxides ("NOX") and mercury from coals burned in circulating 
fluidizer bed boilers and pulverized coal boilers, respectively. 

Our patented CyCleanTM technology, a pre-combustion coal treatment process provides electric power generators the ability to 
enhance combustion and reduce emissions of NOX and mercury from coals burned in cyclone boilers.

Our patents related to the RC segment are not expected to have significant commercial application beyond December 31, 2021 
primarily due to the wind down of Tinuum Group and Tinuum Services as a result of the expiration of the Section 45 tax credit 
period.

Sales and Customers

Through December 31, 2021 we earned royalties ("M-45 Royalties") under a licensing arrangement with Tinuum Group for 
those RC facilities that utilized the M-45 Technology to treat coal for the reduction of emissions of both NOX and mercury. 
With the closure of all of the RC facilities as of December 31, 2021, we will no longer earn M-45 Royalties and the loss of this 
revenue stream will have a material adverse effect on our results of operations and financial position beginning in 2022. For the 
year ended December 31, 2021, M-45 Royalties comprised 14% of our total consolidated revenues and approximately 296% of 
our total consolidated operating income. M-45 Royalties are recognized based upon a percentage of the per-ton, pre-tax margin 
as defined in the M-45 License. 

For 2021 and 2020, we also derived substantial earnings in the RC segment from our equity method investments in Tinuum 
Group and Tinuum Services. Additional information related to major customers is disclosed in Note 21 of the Consolidated 
Financial Statements included in Item 8 of this Report.

Historically, we generated substantial earnings and cash distributions from our ownership in Tinuum Group, which constructed 
RC facilities that were either leased or sold to tax equity investors who earned Section 45 tax credits for the production and sale 
of RC to utilities at their respective RC facilities. We referred to these RC facilities as "invested RC facilities." 

RC facilities that produced and sold RC and were not leased or sold, but wholly or partially owned by us or Tinuum Group, 
were referred to as "retained" RC facilities. Through our direct ownership in retained RC facilities or indirect ownership 
through Tinuum Group, we earned Section 45 tax credits at retained RC facilities for the RC that was produced and sold to 
utilities. For the years ended December 31, 2021 and 2020, we earned $0.4 million and $0.4 million of Section 45 tax credits, 
respectively. As of December 31, 2021, we have cumulatively earned substantial tax credits from certain retained RC facilities, 
but have not been able to fully utilize them. See Note 18 to our Consolidated Financial Statements included in Item 8 - 
"Financial Statements and Supplementary Data" ("Item 8") of this Report for additional information regarding our tax credits 
and other deferred tax assets.

Through December 31, 2021, Tinuum Services operated and maintained RC facilities under operating and maintenance 
agreements with owners or lessees of these RC facilities.

Research and Development Activities

We have conducted research and development directed towards product development related to the Supply Agreement and 
other markets. During the years ended December 31, 2021 and 2020, we incurred expenses of $0.4 million and $1.0 million, 
respectively.

Legislation and Environmental Regulations 

Our products and services, as well as Tinuum Group’s production and sale of RC, are used for the reduction of pollutants and 
other contaminants. Legislation and regulation limit the amount of pollutants and other contaminants permitted and may 
increase the need for our product. Below is a summary of the primary legislation and regulation that affects the market for our 
products.

U.S. Federal Mercury and Air Toxic Standards ("MATS") Affecting Electric Utility Steam Generating Units

The U.S. Environmental Protection Agency ("EPA") final "MATS Rule" went into effect in April 2012. The EPA structured the 
MATS Rule as a Maximum Achievable Control Technology-based ("MACT-based") hazardous pollutant regulation applicable 
to coal and oil-fired Electric Utility Steam Generating Units ("EGU"), which generate electricity through steam turbines and 
have a capacity of 25 megawatts or greater, and provide for, among other provisions, control of mercury, control of acid gases 
such as hydrochloric acid ("HCl") and other Hazardous Air Pollutants ("HAPs"). Approximately 1,260 units in the U.S. were 
coal-fired EGUs when the rule was enacted. According to our estimates, the MATS Rule sets a limit that we believe requires 
the capture of 80-90% plus of the mercury in the coal burned in electric power generation boilers as measured at the exhaust 
stack outlet for most plants. The MACT standards are also known as National Emission Standards for Hazardous Air Pollutants 
("NESHAP"). Plants generally had four years to comply with the MATS Rule, and implementation of the MATS Rule is now 
largely completed. We estimate that 52% of the coal-fired units that were operating in December 2012 when the MATS Rule 
was finalized have been permanently shut down, leaving approximately 518 units in operation in the U.S. at the end of 2021.

In April 2017, a review by the U.S. Court of Appeals for the D.C. Circuit (the "D.C. Circuit") of a 2016 'supplemental finding' 
associated with the cost benefit analysis of the MATS Rule conducted by the EPA was stayed at the request of the Trump 
Administration. The court case continues to be stayed indefinitely. In May 2020, the EPA reconsidered and withdrew its 2016 
"supplemental finding" associated with the cost benefit analysis of the MATS Rule. In this action, EPA found that it was not 
"appropriate and necessary" to regulate HAPs emissions from coal- and oil-fired EGUs. However, the EPA expressly stated that 
the reconsideration neither removed coal- and oil-fired EGUs from the list of sources that must comply with the MATS rule, 
nor rescinded the MATS Rule, which has remained continuously in effect. ADES joined a number of parties in seeking review 
of this EPA action before the D.C. Circuit. President Biden identified EPA’s withdrawal of the supplemental finding as one of 
the actions to be reviewed for conformity with Biden Administration policy, and in February 2021, the Biden Administration 
moved that the pending judicial review of the supplemental finding withdrawal be held in abeyance. On February 9, 2022, the 
EPA published a new proposed rule revoking the May 2020 withdrawal of the 2016 supplemental finding and affirming that it 
is "appropriate and necessary" to regulate HAP emissions from coal- and oil-fired EGUs, which is currently pending. The D.C. 
Circuit granted the Biden Administration’s motion, and this appeal also is now in abeyance. The MATS Rule remains in effect.

State Mercury and Air Toxics Regulations Affecting EGUs

In addition, certain states have their own mercury rules that are similar to or more stringent than the MATS Rule. Coal-fired 
electricity generating units in the U.S are subject to consent decrees that require the control of acid gases and particulate matter, 
in addition to mercury emissions. 

U.S. Federal Industrial Boiler MACT

In January 2013, the EPA issued the final set of adjustments to the MACT-based air toxics standards for industrial boilers, 
including mercury, particulate matter and acid gas emission limits. Existing boilers typically had until January 31, 2017 to 
comply with the rule. On December 1, 2014, the EPA announced the reconsideration of the industrial boiler MACT 
("IBMACT") and proposed amendments to the version published January 31, 2013, representing technical corrections and 
clarifications. The proposed amendments do not affect the applicability of the final rule.

The EPA estimated that approximately 600 coal-fired boilers will be affected by IBMACT, in industries such as pulp and paper. 
Our estimates, based on conversations with plant operators, suggest that most of the affected plants have either shut down or 
switched fuels to natural gas to comply with the regulation.

Effluent Limitation Guidelines

In 2015, the EPA set the first federal limits known as effluent limitation guidelines ("ELGs") on the levels of toxic metals in 
wastewater that can be discharged from power plants. The final rule requires, among other things, zero discharge for fly ash and 
bottom ash transport water, and limits on mercury, arsenic, selenium, and nitrate from flue gas desulfurization ("FGD") 
wastewater. In September 2017, the EPA finalized a rule that delayed the original compliance deadlines for certain wastewater 
streams from November 2018 to November 2020, with the possibility that plants would not need to comply until December 
2023 with state approval. In April 2019, the U.S. Court of Appeals for the Fifth Circuit struck down the EPA’s ELGs that apply 
to leachate wastewater and "legacy wastewater," and directed the EPA to revise the limits on the levels of toxic metals in those 
wastewater streams.  In November 2019, the EPA proposed to revise the ELGs for bottom ash and FGD wastewater. The final 
rule, published in the Federal Register on October 13, 2020 and effective on December 14, 2020, does not directly regulate 
halogens. It does, however, propose to establish a voluntary incentives program for the removal of certain halides. In many 

9

(though not all) of the proposed treatment options that the EPA is considering, selenium in FGD wastewater would be 
regulated. Some halogens may impact the effectiveness of biological wastewater treatment systems that are often used for the 
removal of selenium. On August 3, 2021, the EPA initiated a supplemental rule-making initiative to strengthen certain 
discharge limits and intends to issue a proposed rule for public comment in Fall of 2022. 

Additional U.S. Legislation and Regulations

In 2015, the EPA finalized rules to reduce greenhouse gases ("GHGs") in the form of the Clean Power Plan ("CPP"), which 
established guidelines for states to follow in developing plans to reduce GHG emissions from fossil fuel-fired power plants. 
Under the CPP, states were required to prepare "State Plans" to meet state targets based on emission reductions from affected 
sources. The CPP was challenged by multiple states in the D.C. Circuit. The CPP was stayed by the U.S. Supreme Court. The 
D.C. Circuit held the CPP litigation in abeyance until April 28, 2017, and dismissed the case once the EPA repealed the CPP in 
July 2019.

The EPA repealed the CPP and replaced it with the Affordable Clean Energy ("ACE") rule, which established guidelines for 
states to follow in developing plans to reduce GHG emissions from fossil fuel-fired power plants. ACE also requires states to 
prepare State Plans and prescribes that they must be based on heat rate improvements at affected plants. Numerous states, 
power companies and non-governmental organizations challenged the ACE rule in the D.C. Circuit, which vacated the ACE 
rule on January 19, 2021. On February 12, 2021, EPA stated that neither the ACE or CPP regulations were in place with respect 
to GHGs for fossil fuel-fired power plants.

International Regulations

There are various international regulations related to mercury control. In Canada, the Canada-Wide Standard ("CWS") was 
initially implemented in 2010, with increasingly stringent limits through 2020 and varying mercury emissions caps for each 
province. China and Germany both have limits for mercury emissions that are less stringent than U.S. limits and are typically 
met using co-benefits from other installed air pollution control equipment designed to control other pollutants. In May 2017, the 
EU ratified the Minimata Convention on Mercury, triggering mercury control regulations with implementation starting in 2021. 
Specific emissions limits for dust, nitrogen oxides (NOx), sulfur dioxide (SO2), mercury and particulate matter (PM) are 
currently being developed guided by the best available technologies reference ("BREF") document for limiting stack emissions 
and liquid effluents from industrial processes. The BREF conclusions for large coal-fired electricity generating units were 
adopted by the European Commission in July 2017.

Based on the existing and potential regulations, we believe the international market for mercury control products may expand in 
the coming years. We believe the EMEA Supply Agreement with Cabot will help facilitate positioning our patent portfolio and 
existing commercial products in the EMEA region.

Mining Environmental and Reclamation Matters

Federal, state and local authorities regulate the U.S. coal mining industry with respect to matters such as employee health and 
safety and the environment, including the protection of air quality, water quality, wetlands, special status species of plants and 
animals, land uses, cultural and historic properties and other environmental resources identified during the permitting process. 
Reclamation is required during production and after mining has been completed. Materials used and generated by mining 
operations must also be managed according to applicable regulations and law. 

The Surface Mining Control and Reclamation Act of 1977 ("SMCRA"), establishes mining, environmental protection, 
reclamation and closure standards for all aspects of surface mining. Mining operators must obtain SMCRA permits and permit 
renewals from the Office of Surface Mining (the "OSM") or from the applicable state agency if the state agency has obtained 
regulatory primacy. A state agency may achieve primacy if the state regulatory agency develops a mining regulatory program 
that is no less stringent than the federal mining regulatory program under SMCRA. The Five Forks Mine operates in Louisiana, 
which has achieved primacy and issues permits in lieu of the OSM. The Marshall Mine operates in Texas, which has also 
achieved primacy and issues permits in lieu of the OSM.

Mine operators are often required by federal and/or state laws, including SMCRA, to assure, usually through the use of surety 
bonds, payment of certain long‑term obligations including mine closure or reclamation costs, federal and state workers’ 
compensation costs, coal leases and other miscellaneous obligations. Although surety bonds are usually noncancelable during 
their term, many of these bonds are renewable on an annual basis and collateral requirements may change. As of December 31, 

10

2021, we posted a surety bond of approximately $7.5 million for reclamation of the Five Forks Mine and $16.6 million for the 
reclamation of Marshall Mine.

Patents 

As of December 31, 2021, we held 83 U.S. patents and 12 international patents that were issued or allowed, 15 additional U.S. 
provisional patents or applications that were pending, and two international patent applications that were either pending or filed 
relating to different aspects of our technology. Our existing patents generally have terms of 20 years from the effective date of 
filing, with our next patents expiring beginning in 2022.

Seasonality of Activities 

The sale of our consumable products depends on the operations of the power generation units and industrial facilities in which 
the applicable consumables are provided. Power generation is weather dependent, with electricity and steam production varying 
in response to heating and cooling needs. Additionally, power generating units routinely schedule maintenance outages in the 
spring and/or fall depending on the operation of the boilers. During the period in which an outage may occur, which may range 
from one week to over a month, no consumables are used, and our sales may be correspondingly reduced. 

The sale of our AC products for water purification depends on demand from municipal water treatment facilities where these 
products are utilized. Depending on weather conditions and other environmental factors, the summer months historically have 
the highest demand for PAC, as one of the major uses for PAC is for the treatment of taste and odor episodes caused by 
increased degradation of organic contaminants and natural materials in water during the summer.

Safety, Health and Environment

Our operations are subject to numerous federal, state, and local laws, regulations, rules and ordinances relating to safety, health, 
and environmental matters ("SH&E Regulations"). These SH&E Regulations include requirements to maintain and comply with 
various environmental permits related to the operation of many of our facilities, including mine health and safety laws required 
for continued operation of the Five Forks Mine.

Employees 

As of December 31, 2021, we employed 139 personnel, 27 in Colorado and 112 in Louisiana, all of which were employed full-
time.

Item 1A. Risk Factors   

The following risks relate to us as of the date this Report is filed with the SEC. This list of risks is not intended to be 
exhaustive, but reflects what we believe are the material risks inherent in our business and the ownership of our 
securities as of the specified dates. A statement to the effect that the occurrence of a specified event may have a negative 
impact on our business, results of operations, profitability, financial condition, or the like, is intended to reflect the fact 
that such an event, if it occurs, would be likely to have a negative impact on your investment in ADES, but should not 
imply the likelihood of the occurrence of such specified event. The order in which the following risk factors are 
presented is not intended as an indication of the relative seriousness of any given risk. 

Risks related to our business 

As of December 31, 2021, earnings in our RC segment have substantially ended and beginning in 2022, we will be solely 
dependent on earnings from our APT segment to fund our operations. We will need to grow the earnings from our APT 
segment substantially to make up for the loss of earnings of our RC segment.

The Section 45 tax credit period expired on December 31, 2021. As a result, both Tinuum Group and Tinuum Services have 
substantially ceased operations and we expect to receive limited, final distributions from each during the first half of 2022. 
Substantially all of our earnings and cash flows in 2021 and 2020 were comprised of equity method earnings from Tinuum 
Group and M-45 Royalties generated from certain of Tinuum Group’s invested RC facilities. For the year ended December 31, 
2021, our RC segment generated segment operating income of $82.6 million. 

From an earnings standpoint, our APT segment must grow substantially, either organically or through acquisition, in order to 
replace earnings from our RC segment. There can be no assurance that we will be able to increase our APT segment earnings 
during 2022 or beyond to cover our current operating expenses or to provide a return to shareholders that is comparable to the 
return that we previously provided while our RC segment was operating. We do not expect our overall selling, general and 
administrative portions of our operating expenses to materially decrease in 2022 as a result of the wind down of our RC 
segment. If we are not able to cover operating expenses, we could be forced to raise additional capital, significantly reduce our 
operating expenses or take other alternative actions.

The financial effects of Tinuum Group providing indemnification under performance guarantees of its RC facilities are 
largely unknown and could adversely affect our financial condition. 

Tinuum Group indemnifies certain utilities and lessees of RC facilities for particular risks associated with the operations and tax 
treatment of those facilities. We have provided limited, joint and several guarantees of Tinuum Group’s obligations under those 
leases. Any substantial payments made under such guarantees could have a material adverse effect on our financial condition, 
results of operations and cash flows. 

We are reviewing strategic alternatives and there can be no assurance that we will be successful in identifying or 
completing any strategic transaction, that any such strategic transaction will result in additional value for our 
stockholders or that the process will not have an adverse impact on our business.

We have announced that our board of directors has initiated a strategic review to assess a range of strategic alternatives to 
maximize shareholder value. No timetable has been set for completion of this process, and there can be no assurance that the 
review of strategic alternatives will result in the identification or consummation of any transaction. The process of reviewing 
strategic alternatives may be time consuming and disruptive to our business operations and, if we are unable to effectively 
manage the process, our business, financial condition and results of operations could be adversely affected. We have and will 
continue to incur substantial expenses associated with identifying, evaluating and negotiating potential strategic alternatives. 
There can be no assurance that any potential transaction or other strategic alternative, if consummated, will provide greater 
value to our stockholders than that reflected in the current price of our common stock. Until the review process is concluded, 
perceived uncertainties related to our future may result in the loss of potential business opportunities and volatility in the market 
price of our common stock and may make it more difficult for us to attract and retain qualified personnel and business partners.

Our inability to meet customer supply requirements due to damage to or insufficient production capacity of our Red 
River manufacturing facility may have a material adverse effect on our business, results of operations and financial 
condition.

We own and operate a single activation-based manufacturing plant, which is our sole manufacturing plant for producing and 
selling products to our customers. Our ability to meet customer expectations, manage inventory, complete sales and achieve our 

14

objectives for operating efficiencies depends on the full-time operation of the Red River Plant. We cannot replicate our 
manufacturing methods at another plant due to the limited availability of similar manufacturing plants, the additional costs 
incurred in supplying raw materials such as lignite to another plant, and the risk of revealing our confidential and proprietary 
technologies and manufacturing processes.

If the Red River Plant was destroyed or damaged in a significant manner, we would suffer a loss of inventory to supply 
customers, likely incur additional costs to deliver products to our customers, and disrupt the ordinary course of our business. In 
addition, if contractual demand exceeds manufacturing capacity, we would jeopardize our ability to fulfill obligations under our 
contracts, which could, in turn, result in reduced sales, profitability, contract penalties or terminations and damage to our 
customer relationships and could have a material adverse effect on our business. While we have insured the Red River Plant 
against damage or destruction as well as for losses from business interruptions, there can be no assurance that any insurance 
coverage will be sufficient to cover any such losses.

Further, a prolonged disruption in our operations due to Red River Plant downtime or having to meet customer requirements 
that exceed its maximum manufacturing capacity would require us to seek alternative customer supply arrangements, which 
may not be on attractive terms to us or could lead to delays in distribution of products to our customers, either of which could 
have a material adverse effect on our business, results of operations and financial condition.

Governmental regulations requiring mandatory COVID-19 vaccination of employees could have a material adverse 
impact on our business and results of operations

On September 9, 2021, President Biden issued Executive Order 14042 (the "Executive Order") requiring all employers with 
U.S. Government contracts to ensure that their U.S.-based employees, contractors, and subcontractors that work on or in 
support of U.S. Government contracts are fully vaccinated by December 8, 2021. The executive order includes on-site and 
remote U.S.-based employees, contractors and subcontractors and it only permits limited exemptions for medical and religious 
reasons. The Executive Order is facing legal challenges and currently is enjoined nationwide.

Removal of the injunction of the Executive Order or additional vaccine mandates may be announced in jurisdictions in which 
our business operates. Our implementation of these required policies may result in employee attrition, including attrition of 
critically skilled labor, and difficulty securing future labor needs, which could have a material adverse effect on our business, 
financial condition and results of operations.

The COVID-19 pandemic is expected to continue to affect and pose risks to our business and other epidemics or 
outbreaks of infectious diseases may have a similar impact.

The COVID-19 pandemic has resulted in significant volatility in the general economy. International, federal, state and local 
public health and governmental authorities have taken extraordinary actions to contain and combat the outbreak and spread of 
COVID-19, including travel bans, quarantines, "stay-at-home" orders and similar mandates that caused many individuals to 
substantially restrict their daily activities and many businesses to curtail or cease normal operations. While certain governments 
eased restrictions during the balance of 2020 and 2021, the pandemic remains disruptive to our business operations.

We may not be able to operate at optimal levels of efficiency given new work rules and procedures that were or will be 
implemented to protect our employees, as well as potential increased absenteeism as a result of community spread of 
COVID-19. Any suspension of production at our manufacturing facility, or difficulties or inefficiencies in resuming or 
increasing production, is likely to adversely impact our future results of operations, financial condition and liquidity, and that 
impact may be material. Furthermore, COVID-19 and related supply chain disruptions have impacted and may further impact 
our ability to efficiently operate and may lead to production delays or increased costs of production.

While we are unable to accurately predict the full impact that COVID-19 will have on our results of operations, financial 
condition, liquidity and cash flows due to continued uncertainties, including the duration and severity of the pandemic and 
containment measures, our compliance with these measures has impacted our day-to-day operations and could continue to 
affect our business and operations, as well as that of our key customers, suppliers and other counterparties, for an indefinite 
period of time. The disruptions to our operations caused by COVID-19 have resulted and are expected to continue to result in 
inefficiencies, delays and additional costs in our manufacturing, sales, marketing, and customer service efforts that we cannot 
fully mitigate through remote or other alternative work arrangements. 

The situation surrounding the COVID-19 pandemic remains fluid. The ultimate impact of the COVID-19 pandemic on our 
results of operations, financial condition and liquidity will depend on future developments, some of which are beyond our 
knowledge or control. These include the duration and scope of the pandemic, travel restrictions, government mandated 

15

restrictions and regulations, business and workforce disruptions, the impact on demand for our products, the effectiveness of 
actions taken to contain and treat the disease, including the efficacy of and ability to widely distribute vaccinations and 
therapeutics, and whether the pandemic leads to recessionary conditions in any of our key markets. We will continue to evaluate 
the nature and extent of the impact of COVID-19 to our business.

Demand for our products and services depends significantly on environmental laws and regulations. Uncertainty as to 
the future of such laws and regulations, changes to such laws and regulations or granting of extensions of compliance 
deadlines has had, and will likely continue to have, a material effect on our business.

A significant market driver for our existing products and services and those planned in the future are present and expected 
environmental laws and regulations, particularly those addressing the reduction of mercury and other emissions from coal-fired 
electricity generating units. If such laws and regulations are delayed, or are not enacted or are repealed or amended to be less 
strict, or include prolonged phase-in periods, or are not enforced, our business would be adversely affected by declining 
demand for such products and services. For example:

a.

b.

The implementation of environmental regulations regarding certain pollution control and permitting requirements 
has been delayed from time to time due to various lawsuits. The uncertainty created by litigation and 
reconsiderations of rule-making by the EPA has negatively impacted our business, results of operations and 
financial condition and will likely continue to do so. 

To the extent federal, state and local legislation mandating that electric power generating companies serving a state 
or region purchase a minimum amount of power from renewable energy sources such as wind, hydroelectric, solar 
and geothermal, and such amount lessens demand for electricity from coal-fired plants, the demand for our 
products and services would likely decrease. 

Federal, state and international laws or regulations addressing emissions from coal-fired electricity generating units, climate 
change or other actions to limit emissions, including public opposition to new coal-fired electricity generating units, has caused 
and could continue to cause electricity generators to transition from coal to other fuel and power sources, such as natural gas, 
nuclear, wind, hydroelectric and solar. The potential financial impact on us of future laws or regulations or public pressure will 
depend upon the degree to which electricity generators diminish their reliance on coal as a fuel source. That, in turn, will 
depend on a number of factors, including the specific requirements imposed by any such laws or regulations, the periods over 
which those laws or regulations are or will be phased in, the amount of public opposition and the state and cost of commercial 
development of related technologies and processes. In addition, Public Utility Commissions ("PUCs") may not allow utilities to 
charge consumers for, and pass on the cost of, emissions control technologies without federal or state mandates. We cannot 
reasonably predict the impact that any such future laws or regulations or public opposition may have on our results of 
operations, financial condition or cash flows.

Action by the EPA related to MATS that decreases demand for our mercury removal products could have a material 
adverse effect on our APT segment.

Performance in our APT segment is largely dependent upon demand for mercury removal-related product, which is largely 
affected by the amount of coal-based power generation used in the U.S. and the continued regulation of utilities under MATS. 
In May 2020, the EPA reconsidered and withdrew its 2016 "supplemental finding" associated with the cost benefit analysis of 
the MATS Rule. In this action, the EPA found that it was not "appropriate and necessary" to regulate HAP emissions from coal- 
and oil-fired EGUs. However, the EPA expressly stated that the reconsideration neither removed coal- and oil-fired EGUs from 
the list of sources that must comply with the MATS rule, nor rescinded the MATS Rule, which has remained continuously in 
effect. On February 9, 2022, the EPA published a new proposed rule revoking the May 2020 withdrawal of the 2016 
supplemental finding and affirming that it is "appropriate and necessary" to regulate HAP emissions from coal- and oil-fired 
EGUs. Any final action taken by the EPA related to MATS that decreases demand for our products for mercury removal will 
have a negative effect on the financial results of our APT segment. The timing and content of the final reconsideration rule are 
unknown.

Uncertain geopolitical conditions could adversely affect our business.

Uncertain geopolitical conditions, including the invasion of Ukraine, sanctions against Russia and other potential impacts on 
this region's economic environment and currencies may cause disruptions in our business. These include logistics delays or 
shortages in producing and shipping certain of our raw materials, increases in energy prices that could increase costs of certain 

16

of our raw materials, increases in transportation costs from overall higher gasoline prices and cyber-attacks targeted at U.S. 
power infrastructure that could impact demand for our products. 

The failure of tariffs placed on U.S. imports of Chinese activated carbon to adequately address the impact of low-priced 
imports from China could have a material adverse effect on the competitiveness and financial performance of our APT 
segment.

Our APT segment faces competition in the U.S. from low-priced imports of activated carbon products. If the volumes of these 
low-priced imports increase, especially if they are sold at less than fair value, our sales of competing products could decline, 
which could have an adverse effect on the earnings of our APT segment. In addition, sales of these low-priced imports may 
negatively impact our pricing. To limit these activities, regulators in the U.S. have enacted an anti-dumping duty order on steam 
activated carbon products from China. In 2018, the order was extended for an additional five years. The amount of anti-
dumping duties collected on imports of steam activated carbon from China is reviewed annually by the U.S. Department of 
Commerce. To the extent the anti-dumping margins do not adequately address the degree to which imports are unfairly traded, 
the anti-dumping order may be less effective in reducing the volume of these low-priced activated carbon imports in the U.S., 
which could negatively affect demand and/or pricing for our AC products.

The market for consumables and other products that provide pollutant reduction is highly competitive and some of our 
competitors are significantly larger and more established than we are, which could adversely impede our growth 
opportunities and financial results.

We operate in a highly competitive marketplace. Our ability to compete successfully depends in part upon our ability to 
maintain a production cost advantage, competitive technological capabilities and to continue to identify, develop and 
commercialize new and innovative products for existing and future customers. We may face increased competition from 
existing or newly developed products offered by industry competitors or other companies whose products offer a similar 
functionality as our products and could be substituted for our products, which may negatively affect demand for our products. 
In addition, market competition could negatively impact our ability to maintain or raise prices or maintain or grow our market 
position.

We compete against certain significantly larger and/or more established companies in the market for consumables and other 
products that provide mercury emissions reduction, water treatment and air purification.

Reduction of coal consumption by North American electricity power generators could result in less demand for our 
products and services. If utilities significantly reduce the number of coal-fired electricity generating units or the amount 
of coal burned without a corresponding increase in the services required at the remaining units, this could reduce our 
revenues and materially and adversely affect our business, financial condition and results of operations.

The amount of coal consumed for North American electricity power generation is affected by, among other things, (1) the 
location, availability, quality and price of alternative energy sources for power generation, such as natural gas, fuel oil, nuclear, 
hydroelectric, wind, biomass and solar power; and (2) technological developments, including those related to competing 
alternative energy sources.

Natural gas-fueled generation and renewable energy generation has been displacing and may continue to displace coal-fueled 
generation, particularly from older, less efficient coal-powered generators. We expect that a significant amount of the new 
power generation necessary to meet increasing demand for electricity generation will be fueled by these sources. The price of 
natural gas has remained relatively competitive for power generation and the use of natural gas is perceived as having a lower 
environmental impact than burning coal. Natural gas-fired plants are cheaper to construct, and permits to construct these plants 
are easier to obtain, and ongoing costs of natural gas-fired plants associated with meeting environmental compliance are lower. 
Possible advances in technologies and incentives, such as tax credits, that enhance the economics of renewable energy sources 
could make those sources more competitive than coal. Any reduction in the amount of coal consumed by domestic electricity 
power generators, whether as a result of new power plants utilizing alternative energy sources or as a result of technological 
advances, could reduce the demand for our current products and services, thereby reducing our revenues and materially and 
adversely affecting our business and results of operations.

Additionally, long-term changes in environmental regulation that threaten or preclude the use of coal or other fossil fuels as a 
primary fuel source for electricity production may result in the reduction or closure of a significant number of coal-fired electric 
generating units, and may adversely affect our business, financial condition and results of operations.

17

The loss of, or significant reduction in, purchases by our largest customers could adversely affect our business, financial 
condition or results of operations.

During the year ended December 31, 2021, we derived approximately 50% of our total consumable revenues from our five 
largest customers. Our top three customers accounted for approximately 37% of our total consumable revenue for our last fiscal 
year. If any of our five largest customers were to significantly reduce the quantities of consumables they purchase from us, it 
may adversely affect our business, financial condition and results of operations.

Volatility in price and availability of raw materials can significantly impact our results of operations.

The manufacturing and processing of our consumable products requires significant amounts of raw materials. The price and 
availability of those raw materials can be impacted by factors beyond our control. Our consumable products, exclusive of 
lignite coal, use a variety of additives. Significant movements or volatility in the costs of additives could have an adverse effect 
on our working capital or results of operations. Additionally, we obtain certain raw materials from selected key suppliers. While 
we have inventory of such raw materials, if any of these suppliers are unable to meet their obligations with us on a timely basis 
or at an acceptable price, we may be forced to incur higher costs to obtain the necessary raw materials or be unable to obtain the 
materials.

We may attempt to offset the increase in raw material costs or challenges in the supply of raw materials with price increases 
allowed in our contractual relationships or through cost reduction efforts. If we are unable to fully offset the increased cost of 
raw materials through price increases, it could significantly impact our business, financial condition and results of operations. 

We face operational risks inherent in mining operations and our mining operations have the potential to cause safety 
issues, including those that could result in significant personal injury.

We own the Five Forks Mine, a lignite coal mine located in Louisiana, which is operated for us by a third party. Mining 
operations by their nature involve a high level of uncertainty and are often affected by risks and hazards outside of our control. 
At the Five Forks Mine, the risks are primarily operational risks associated with the maintenance and operation of the heavy 
equipment required to dig and haul the lignite and risks relating to producing lower than expected lignite quality or recovery 
rates. The failure to adequately manage these risks could result in significant personal injury, loss of life, damage to mineral 
properties, production facilities or mining equipment, damage to the environment, delays in or reduced production and potential 
legal liabilities.

We also own the Marshall Mine, a former lignite coal mine located in Texas, which ceased mining operations in the third 
quarter of 2020 and is currently being reclaimed. Reclamation operations by their nature involve a high level of uncertainty and 
are often affected by risks and hazards outside of our control. At the Marshall Mine, the current risks are primarily operational 
risks associated with the maintenance and operation of the heavy equipment. The failure to adequately manage these risks could 
result in significant personal injury, loss of life, equipment, damage to the environment, delays in reclamation and potential 
legal liabilities.

18

Our operations and products are subject to extensive safety, health and environmental requirements that could increase 
our costs and/or impair our ability to manufacture and sell certain products.

Our ongoing operations are subject to extensive federal, state and local laws, regulations, rules and ordinances relating to safety, 
health and environmental matters, many of which provide for substantial monetary fines and potential criminal sanctions for 
violations. These include requirements to obtain and comply with various environmental-related permits for constructing any 
new facilities (or modifications to existing facilities) and operating all of our existing facilities. In addition, our Red River Plant 
may become subject to greenhouse gas emission trading requirements under which we may be required to purchase emission 
credits if our emission levels exceed our allocations. Greenhouse gas regulatory programs that have been adopted, such as cap-
and-trade programs, have not had a significant impact on our business to date. Costs of complying with regulations could 
increase, as concerns related to greenhouse gases and climate change continue to emerge. The enactment of new environmental 
laws and regulations and/or the more aggressive interpretation of existing requirements could require us to incur significant 
costs for compliance or capital improvements or limit our current or planned operations, any of which could have a material 
adverse effect on our earnings or cash flow. We may attempt to offset the effects of these compliance costs through price 
increases, productivity improvements and cost reduction efforts, and our success in offsetting any such increased regulatory 
costs is largely influenced by competitive and economic conditions and could vary significantly depending on the market 
segment served. Such increases may not be accepted by our customers, may not be sufficient to compensate for increased 
regulatory costs or may decrease demand for our products and our volume of sales. 

We may not be successful in achieving our growth expectations related to new products in our existing or new markets.

We may not be successful in achieving our growth expectations from developing new products for our existing or new markets. 
Further, we cannot ensure costs incurred to develop new products will result in an increase in revenues. Additionally, our ability 
to bring new products to the market will depend on various factors, including, but not limited to, solving potential technical or 
manufacturing difficulties, competition and market acceptance, which may hinder the timeliness and cost to bring such products 
to production. These factors or delays could affect our future operating results.

We may not be successful in realizing the benefits associated with our acquisitions, dispositions and strategic 
partnerships, and our business could be adversely affected.

We have and may in the future expand the our scope of products, services, and technologies through selective acquisitions, 
investments or creating partnerships and joint ventures. We may also dispose of assets or portions of our business that no longer 
complement our long-term strategic objectives. We continually evaluate potential acquisition, disposition, and strategic 
partnership opportunities in the ordinary course of business. Acquisitions, dispositions, and strategic partnerships involve 
numerous risks, including among others:

•

•

•

•

•

•

•

•

•

•

•

inability to negotiate favorable prices and terms;

incorrect evaluations of the synergies and/or long-term benefits of the acquisition, disposition, and strategic 
partnership;

integration difficulties, including challenges and costs associated with implementing systems, processes and controls to 
comply with the requirements of a publicly-traded company;

diverting management’s attention;

litigation arising from acquisition and disposition activity;

potential increased debt leverage;

potential issuance of dilutive equity securities;

entering markets in which we have no or limited direct prior experience and where competitors in such markets have 
stronger market positions;

unanticipated costs and exposure to undisclosed or unforeseen liabilities or operating challenges;

potential goodwill or other intangible asset impairments;

potential requirements to provide transition services in connection with a disposition, which may result in the diversion 
of resources and focus of management and employees;

19

•

•

•

potential loss of key employees and customers of the acquired businesses, product or service lines, assets or 
technologies;

our ability to properly establish and maintain effective internal controls over an acquired company; and

increasing demands on our operational and IT systems.

The success of an acquisition, disposition or strategic partnership is not always predictable, and we may not be successful in 
realizing our objectives as anticipated, and our business may be adversely affected as a result.

Natural disasters could affect our operations and financial results.

We operate facilities, including the Red River Plant and Five Forks Mine, that are exposed to natural hazards, such as floods, 
windstorms and hurricanes. Extreme weather events present physical risks that may become more frequent as a result of factors 
related to climate change. Such events could disrupt our supply of raw materials or otherwise affect production, transportation 
and delivery of our products or affect demand for our products.

In addition, extreme and unusually cold or hot temperatures throughout the U.S. could result in abnormally high loads on 
geographic electrical grids that could result in the failure of coal-fired power plants to produce electricity. If these plants were 
off-line for a significant period of time, the demand for our products could be less, which would impact our operations and 
financial results. Conversely, abnormally high loads on geographic electrical grids, resulting in increased demand of coal-fired 
power plants to produce electricity, could impact our ability to meet customer contracts and demands.

Information technology vulnerabilities and cyberattacks on our networks could have a material adverse impact on our 
business.

We rely on information technology ("IT") to manage and conduct business, both internally and externally, with our customers, 
suppliers and other third parties. Internet transactions involve the transmission and storage of data including, in certain 
instances, customer and supplier business information. Therefore, maintaining the security of computers and other electronic 
devices, computer networks and data storage resources is a critical issue for us and our customers and suppliers because 
security breaches could result in reduced or lost ability to carry on our business and loss of and/or unauthorized access to 
confidential information. 

We have limited personnel and other resources to address information technology reliability and security of our computer 
networks and to respond to known security incidents to minimize potential adverse impact. Experienced hackers, 
cybercriminals and perpetrators of threats may be able to penetrate our network security and misappropriate or compromise our 
confidential information or that of third parties, create system disruptions or cause shutdowns. These perpetrators of 
cyberattacks also may be able to develop and deploy viruses, worms, malware and other malicious software programs that 
attack our information and networks or otherwise exploit any security vulnerabilities of our information and networks. 

Techniques used to obtain unauthorized access to or sabotage systems change frequently and often are not recognized until after 
they are launched against a target, and we may be unable to anticipate these techniques or to implement adequate preventative 
measures. A breach of our IT systems and security measures as a result of third party action, malware, employee error, 
malfeasance or otherwise could materially adversely impact our business and results of operations and expose us to customer, 
supplier and other third party liabilities.

Risks related to intellectual property

Failure to protect our intellectual property or infringement of our intellectual property by a third party could have an 
adverse impact on our financial condition.

We rely on a combination of patent, copyright and trademark laws, trade secrets, confidentiality procedures and contractual 
provisions to protect our proprietary rights. Such means of protecting our proprietary rights may not be adequate because they 
provide only limited protection or such protection may be prohibitively expensive to enforce. We also enter into confidentiality 
and non-disclosure agreements with our employees, consultants and many of our customers and vendors, and generally control 
access to and distribution of our proprietary information. Notwithstanding these measures, a third party could copy or otherwise 
obtain and use our proprietary information without authorization. We cannot provide assurance that the steps we have taken 
will prevent misappropriation of our technology and intellectual property, which could negatively impact our business and 

20

financial condition. In addition, such actions by third parties could divert the attention of our management from the operation of 
our business.

We may be subject to intellectual property infringement claims from third parties that are costly to defend and that 
may limit our ability to use the disputed technologies.

If our technologies are alleged to infringe the intellectual property rights of others, we may be forced to mount a defense to such 
claims, which may be expensive and time consuming. During the pendency of litigation, we could be prevented from marketing 
and selling existing products or services and from pursuing research, development or commercialization of new or 
complimentary products or services. Further, we may be required to obtain licenses to third party intellectual property or be 
forced to develop or obtain alternative technologies. Our failure to obtain a license to a technology that we may require, or the 
need to develop or obtain alternative technologies, could significantly and negatively affect our business.

Indemnification of third-party licensees of our technologies against intellectual property infringement claims concerning 
our licensed technology and our products could be financially significant to us.

We have agreed to indemnify licensees of our technologies (including Tinuum Group) and purchasers of our products, and we 
may enter into additional agreements with others under which we agree to indemnify and hold them harmless from losses they 
may incur as a result of the alleged infringement of third-party rights caused by the use of our technologies and products. 
Infringement claims, which are expensive and time-consuming to defend, could have a material adverse effect on our business, 
operating results and financial condition, even if we are successful in defending ourselves (and the indemnified parties) against 
them.

Our future success depends in part on our ongoing identification and development of intellectual property and our 
ability to invest in and deploy new products, services and technologies into the marketplace efficiently and cost 
effectively.  

The process of identifying customer needs and developing and enhancing products, services and solutions for our business 
segments is complex, costly and uncertain. Any failure by us to identify and anticipate changing needs, emerging trends and 
new regulations could significantly harm our future market share and results of operations. 

Risk related to tax matters

An "ownership change" could limit our ability to utilize tax loss and credit carryforwards to offset future taxable 
income. 

We have certain general business credit tax credits ("Tax Credits"). As of December 31, 2021, we had $86.1 million of Tax 
Credits, equaling 87% of our total gross deferred tax assets. Our ability to use these Tax Credits to offset future taxable income 
may be significantly limited if we experience an "ownership change" as discussed below. Under the Internal Revenue Code 
("IRC') and regulations promulgated by the U.S. Treasury Department, we may carry forward or otherwise utilize the Tax 
Credits in certain circumstances to offset any current and future taxable income, and thus reduce our federal income tax 
liability, subject to certain requirements and restrictions. To the extent that the Tax Credits do not otherwise become limited, we 
believe that we will have available a significant amount of Tax Credits in future years, and therefore the Tax Credits could be a 
substantial asset to us. However, if we experience an "ownership change," as defined in Sections 382 and 383 of the IRC, our 
ability to use the Tax Credits may be substantially limited, and the timing of the usage of the Tax Credits could be substantially 
delayed, which could therefore significantly impair the value of that asset. 

In general, an "ownership change" under Sections 382 and 383 occurs if the percentage of stock owned by an entity’s 5% 
stockholders (as defined for tax purposes) increases by more than 50 percentage points over a rolling three-year period. An 
entity that experiences an ownership change generally will be subject to an annual limitation on its pre-ownership change tax 
loss and credit carryforwards equal to the equity value of the entity immediately before the ownership change, multiplied by the 
long-term, tax-exempt rate posted monthly by the IRS (subject to certain adjustments). The annual limitation would be 
increased each year to the extent that there is an unused limitation in a prior year. The limitation on our ability to utilize the Tax 
Credits arising from an ownership change under Sections 382 and 383 of the IRC would depend on the value of our equity at 
the time of any ownership change.  If we were to experience an "ownership change," it is possible that a significant portion of 
our tax credit carryforwards could expire before we would be able to use them to offset future taxable income.

On May 5, 2017, our Board of Directors (the "Board") approved the Tax Asset Protection Plan (the "TAPP") and declared a 
dividend of one preferred share purchase right (each, a "Right") for each outstanding share of our common stock. The TAPP 

21

was adopted in an effort to protect stockholder value by attempting to diminish the risk that our ability to use the Tax Credits to 
reduce potential future federal income tax obligations may become substantially limited. On April 9, 2021, the Board approved 
the Fourth Amendment to the TAPP ("Fourth Amendment") that amends the TAPP, as previously amended by the First, Second 
and Third Amendments that were approved the Board on April 6, 2018, April 5, 2019 and April 9, 2020, respectively. The 
Fourth Amendment amends the definition of "Final Expiration Date" under the TAPP to extend the duration of the TAPP and 
makes associated changes in connection therewith. At the Company's 2021 annual meeting of stockholders, the Company's 
stockholders approved the Fourth Amendment, thus the Final Expiration Date will be the close of business on December 31, 
2022.

The TAPP, as amended, is intended to act as a deterrent to any person acquiring beneficial ownership of 4.99% or more of our 
outstanding common stock without the approval of the Board. Stockholders who beneficially owned 4.99% or more of our 
outstanding common stock upon execution of the Protection Plan will not trigger the Protection Plan so long as they do not 
acquire beneficial ownership of additional shares of our common stock. The Board may, in its sole discretion, also exempt any 
person from triggering the Protection Plan.

Risks related to our common stock

Our stock price is subject to volatility.

The market price of our common stock has experienced substantial price volatility in the past and may continue to do so. The 
market price of our common stock may continue to be affected by numerous factors, including:

a.

b.

c.

d.

e.

f.

g.

h.

i.

j.

k.

actual or anticipated fluctuations in our operating results and financial condition; 

changes in laws or regulations and court rulings and trends in our industry; 

announcements of sales awards; 

changes in supply and demand of components and materials; 

adoption of new tax regulations or accounting standards affecting our industry; 

changes in financial estimates by securities analysts; 

perceptions of the value of corporate transactions; 

trends in social responsibility and investment guidelines;

whether we are able and elect to pay cash dividends;

the continuation of repurchasing shares of common stock under stock repurchase programs; and

the degree of trading liquidity in our common stock and general market conditions.

From January 1, 2020 to December 31, 2021, the closing price of our common stock ranged from $3.76 to $12.49 per share. In 
June 2017, we commenced a quarterly cash dividend program and paid out cash dividends in each succeeding quarter through 
March 31, 2020. In 2018, we implemented stock repurchase programs, and repurchased a total of 20,613 shares of our common 
stock for the fiscal years 2021 and 2020 for cash of $0.2 million. 

Stock price volatility over a given period may cause the average price at which we repurchase shares of our common stock to 
exceed the stock’s price at a given point in time. We believe our stock price should reflect expectations of future growth and 
profitability. Future dividends are subject to declaration by the Board, and under our current stock repurchase program, we are 
not obligated to acquire any specific number of shares. If we fail to meet expectations related to future growth, profitability, 
dividends, stock repurchases or other market expectations, our stock price may decline significantly, which could have a 
material adverse impact on our ability to obtain additional capital and erode investor confidence, which could further reduce the 
liquidity of our common stock. We do not expect to repurchase additional shares of our common stock in the near term.

We are unlikely to resume our quarterly cash dividend program.

The Board first approved a $0.25 per share of common stock quarterly dividend in June 2017. We last paid a cash dividend on

With the ceasing of our cash-generating RC segment, it is unlikely, for the foreseeable future, that we will resume declaring 
quarterly cash dividends under a dividend program. The payment of future dividends will be affected by, among other factors:  
(1) our views on potential future capital requirements for investments in acquisitions; (2) legal risks; (3) stock repurchase 
programs; (4) changes in federal and state income tax laws or corporate laws; (5) changes to our business model; and (6) any 
additional indebtedness that we may incur in the future. 

Our certificate of incorporation and bylaws contain provisions that may delay or prevent an otherwise beneficial 
takeover attempt of us.

Certain provisions of our certificate of incorporation and bylaws could make it more difficult for a third party to acquire us, 
even if doing so would be beneficial to our stockholders. These include provisions that:

a.

b.

c.

d.

Limit the business at special meetings of stockholders to the purpose stated in a notice of the meeting; 

Authorize the issuance of "blank check" preferred stock, which is preferred stock with voting or other rights or 
preferences that could impede a takeover attempt and that the Board can create and issue without prior stockholder 
approval; 

Establish advance notice requirements for submitting nominations for election to the Board and for proposing 
matters that can be acted upon by stockholders at a meeting; and 

Require the affirmative vote of the "disinterested" holders of a majority of our common stock to approve certain 
business combinations involving an "interested stockholder" or its affiliates, unless either minimum price criteria or 
procedural requirements are met, or the transaction is approved by a majority of our "continuing directors" (known 
as "fair price provisions"). 

These provisions, alone or in combination with each other, may discourage transactions involving actual or potential changes of 
control, including transactions that otherwise could involve payment of a premium over prevailing market prices to holders of 
our common stock, or could limit the ability of our stockholders to approve transactions that they may deem to be in their best 
interest.

An increased focus on environmental, social and governance factors by institutional investors may negatively impact 
our access to capital and the liquidity of our stock price. 

Some institutional investors have recently adopted Environmental, Social and Governance ("ESG") investing guidelines that 
may prevent them from increasing or taking new stakes with companies with exposure to fossil fuels. Additional institutional 
investors may adopt similar ESG investment guidelines. This could limit both the demand for owning our common stock and/or 
our access to capital. If such capital is desired, we cannot assure you that we will be able to obtain any additional equity or debt 
financing on terms that are acceptable to us. Given these emerging trends, liquidity in our common stock and our stock price 
may be negatively impacted.

We may require additional funding for our growth plans, and such funding may require us to issue additional shares of 
our common stock, resulting in a dilution of your investment.

We  estimate  our  funding  requirements  in  order  to  implement  our  growth  plans.  If  the  actual  funding  required  to  implement 
growth initiatives should exceed funding estimates significantly, or our funds generated from our operations from such growth 
initiatives prove insufficient for such purposes, we may need to raise additional funds to meet these funding requirements.

These additional funds may be raised by issuing equity or debt securities or by borrowing from banks or other resources. We 
cannot assure you that we will be able to obtain any additional financing on terms that are acceptable to us, or at all. If we fail to 
obtain  additional  financing  on  terms  that  are  acceptable  to  us,  we  may  not  be  able  to  implement  such  plans  fully.  Such 
financing,  even  if  obtained,  may  be  accompanied  by  conditions  that  limit  our  ability  to  pay  dividends  or  require  us  to  seek 
lenders’  consent  for  payment  of  dividends,  or  restrict  our  ability  to  operate  our  business  by  requiring  lender’s  consent  for 
certain corporate actions. Further, if we raise additional funds through the issuance of new shares of our common stock, any 
shareholders who are unable or unwilling to participate in such an additional round of fund raising may suffer dilution of their 
investment.

None.

Item 2. Properties

Office and Facilities

We lease approximately 24,000 square feet of office space in Greenwood Village, Colorado for our corporate headquarters and 
primary research and development laboratory. 

We own our manufacturing plant, which is located on approximately 59 acres in Coushatta, Louisiana. We also lease 6.9 acres 
in Natchitoches Parish, Louisiana where we operate a manufacturing and distribution facility.

The APT segment of our business utilizes all of our office and facilities space.

Mining

The APT segment of our business utilizes all of our mining and mining-related properties.

As of December 31, 2021, we owned or controlled primarily through long-term leases approximately 4,425 acres of coal land 
for surface mining. Of those acres, approximately 1,975 acres are located in Natchitoches Parish, Louisiana ("Five Forks"). The 
majority of the Five Forks land is leased for mineral rights and right-of-use purposes that expire at varying dates over the next 
30 years and contain options to renew. The remaining land is owned by us. 

Under our current mining plans, substantially all leased reserves will be mined out within the period of existing leases or within 
the time period of assured lease renewals. Royalties are paid to lessors either as a fixed price per ton or as a percentage of the 
gross sales price of the mined coal. The majority of the significant leases are on a percentage royalty basis. In some cases, a 
payment is required either at the time of execution of the lease or in annual installments. In most cases, the prepaid royalty 
amount is applied to reduce future production royalties.

The remaining 2,450 acres (of 4,425 acres of coal land for surface mining) pertain to the Marshall Mine, which is located in 
Harrison and Panola Counties, Texas. Mining operations on this land ceased in the third quarter of 2020.

Based on the materiality and the vertically-integrated company guidelines contained in Regulation S-K of the Securities Act and 
the Exchange Act, we have concluded that no additional disclosures related to our mining operations are required under this 
Item.  

Item 3. Legal Proceedings

From time to time, we are involved in various litigation matters arising in the ordinary course of our business. Information with 
respect to this item may be found in Note 14 "Commitments and Contingencies" to the Consolidated Financial Statements 
included in Item 8 of this Report.

Item 4. Mine Safety Disclosures

The statement concerning mine safety violations or other regulatory matters required by Section 1503(a) of the Dodd-Frank 
Wall Street Reform and Consumer Protection Act and Item 104 of Regulation S-K is included in Exhibit 95 to this Report.

PART II

Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity 
Securities

Market for Our Common Stock

As of December 31, 2021, our common stock was quoted on the Nasdaq Global Market under the symbol "ADES." The trading 
volume for our common stock is relatively limited. There is no assurance that an active trading market will provide adequate 
liquidity for our existing stockholders or for persons who may acquire our common stock in the future.

Dividends 

In June 2017, we commenced a quarterly cash dividend program of $0.25 per common share and made our most recent 
payment in March 2020. Currently, we do not plan to recommence a quarterly cash dividend program in the near term.

In the future, we may declare and pay a cash dividend on shares of our common stock. Whether we do, however, and the timing 
and amounts of dividends will be subject to approval and declaration by the Board and will depend on a variety of factors 
including, but not limited to, our financial results, cash requirements, financial condition and other contractual restrictions and 
other factors considered relevant by the Board, and will be subject to limitations imposed under Delaware law.

Holders

The number of holders of record of our common stock as of February 25, 2022 was approximately 900. The approximate 
number of beneficial stockholders is estimated at 7,800. 

Purchases of Equity Securities by the Company and Affiliated Purchasers

We had no repurchases of our common stock for the three months ended December 31, 2021. 

We maintain a program to repurchase up to $20.0 million of shares of our common stock under a stock repurchase program (the 
"Stock Repurchase Program") through open market transactions at prevailing market prices. The Board subsequently approved 
an amendment to The Stock Repurchase Program in which it authorized an incremental $7.1 million, resulting in a total of 
$10.0 million of shares of our common stock allowable to repurchase. As of December 31, 2021, $7.0 million of shares of our 
common stock remained outstanding for repurchase under the Stock Repurchase Program, which will remain in effect until all 
amounts are utilized or it is otherwise modified by the Board.

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

Overview 

Through December 31, 2021, we operated two segments: RC and APT. Our RC segment is comprised of our equity ownership 
in Tinuum Group and Tinuum Services, both of which are unconsolidated entities from which we generated substantial 
earnings. Tinuum Group provides reduction of mercury and NOx emissions at select coal-fired power generators through the 
production and sale of RC that qualifies for Section 45 tax credits under IRC Section 45. We benefited from Tinuum Group's 
production and sale of RC, which generated Section 45 tax credits, as well as its revenue from selling or leasing RC facilities to 
tax equity investors. We also earned royalties for technologies that we licensed to Tinuum Group, which were used at certain 
RC facilities to enhance combustion and reduce emissions of NOx and mercury from coal burned to generate electrical power. 
Tinuum Services operated and maintained the RC facilities under operating and maintenance agreements with Tinuum Group 
and owners or lessees of the RC facilities. Effective December 31, 2021, the Section 45 tax credit period expired and as a result 
both Tinuum Group and Tinuum Services have substantially ceased their operations. As such, our earnings and distributions 
from our RC segment substantially ceased as of December 31, 2021. We expect to receive limited, additional cash distributions 
from Tinuum Group and Tinuum Services during the first half of 2022.

Our APT segment is primarily comprised of operations of our wholly-owned subsidiary, Carbon Solutions, which we acquired 
on December 7, 2018. We sell consumable products that utilize AC and chemical based technologies to a broad range of 
customers, including coal-fired utilities, industrials, water treatment plants and other diverse markets. Our primary products are 
comprised of AC, which is produced from lignite coal. Our AC products include PAC and GAC. Our proprietary technologies 
and associated product offerings provide purification solutions to enable our customers to reduce certain contaminants and 
pollutants to meet the challenges of existing and potential regulations. Additionally, we own an associated lignite mine which 
supplies the primary raw material for manufacturing our products.

See further discussion of our business included in Item 1 - "Business" ("Item 1") of this Report. Discussion regarding segment 
information is included in the discussion of our consolidated results under this Item 7. Additionally, discussion related to our 
reportable segments is included in Item 1 and Note 19 of the Consolidated Financial Statements, which is included in Item 8 of 
this Report.

We believe there are opportunities and are continuing to pursue diverse markets for our purification products outside of coal-
fired power generation, including industrial applications and water. The Supply Agreement with Cabot, as discussed below, 
continues to expand sales of our AC products to those diverse end-markets and drive the Company’s post-Refined Coal future. 

Review of Strategic Alternatives

In May 2021, we announced that we had retained Ducera Partners, LLC as our financial advisor to assist in a strategic review 
process to assess a range of strategic alternatives to enhance value for our stockholders. We cannot provide any assurance that 
the exploration of strategic alternatives will result in the identification or consummation of any transaction. Similarly, any 
strategic decision will involve risks and uncertainties, and we cannot provide any assurance that any strategic alternative, if 
identified, evaluated and consummated, will provide the anticipated benefits or otherwise enhance stockholder value. The 
process is ongoing and our board of directors has not set a timetable for completion of the evaluation.

Drivers of Demand and Key Factors Affecting Profitability

Drivers of demand and key factors affecting our profitability differ by segment. Historically, we derived substantial earnings 
and cash distributions from the RC segment through our equity ownership in Tinuum Group and Tinuum Services as well as the 
royalties earned from a licensing arrangement with Tinuum Group for use of our M-45 Technology. With the expiration of the 
Section 45 tax credit period, we will no longer generate earnings from either Tinuum Group or Tinuum Services. Additionally, 
we do not expect our overall selling, general and administrative portions of our operating expenses to materially decrease in 
2022 as a result of the wind down of our RC segment. 

Demand in the APT segment is driven primarily by consumables-based solutions for coal-fired power generation, municipal 
water treatment and other industrial customers; and since the fourth quarter of 2020, demand from Cabot's customers through 
the Supply Agreement discussed below. Operating results in the APT segment have been influenced by: (1) changes in our sales 
volumes; (2) changes in price and product mix; (3) changes related to non-integrated supply chain inputs and (4) changes in 
coal-fired dispatch and electricity power generation sources. For the year ended December 31, 2021, we observed significant 

26

increases in demand for our AC product. As such, we continue to purchase inventory to meet our customer demands to 
supplement products manufactured at our Red River Plant. 

Customer Supply Agreement

On September 30, 2020, we and Cabot entered into the Supply Agreement, pursuant to which we agreed to sell and deliver to 
Cabot, and Cabot agreed to purchase and accept from us, Furnace Products. The term of the Supply Agreement is for 15 years 
with 10-year renewal terms that are automatic unless either party provides three years prior notice of intention not to renew 
before the end of any term.

The Supply Agreement has provided material incremental volume and allowed us to capture operating cost efficiencies at our 
Red River manufacturing plant. The incremental volumes from the Supply Agreement have improved fixed cost absorption and 
resulted in increased gross margins. Further, the Supply Agreement has expanded our AC products to diverse end markets that 
are outside of markets we historically served.

Acquisition of Marshall Mine

Concurrently with the execution of the Supply Agreement, on September 30, 2020, we entered into the Mine Purchase 
Agreement from Cabot for 100% of the membership interests in Marshall Mine, LLC (the "Marshall Mine Acquisition") for a 
nominal purchase price. Marshall Mine, LLC owns a lignite mine located outside of Marshall, Texas (the "Marshall Mine"). We 
independently determined to immediately commence activities to shutter the Marshall Mine and to incur the associated 
reclamation costs.

In conjunction with the execution of the Supply Agreement and the Mine Purchase Agreement, on September 30, 2020, we 
entered into the Reclamation Contract with a third party that provides a capped cost, subject to certain contingencies, in the 
amount of approximately $19.7 million plus an obligation to pay certain direct costs of approximately $3.6 million 
(collectively, the "Reclamation Costs") over the estimated reclamation period of 10 years. Under the terms of the Supply 
Agreement, Cabot is obligated to reimburse us for approximately $10.2 million of Reclamation Costs (the "Reclamation 
Reimbursement"), which are payable semi-annually over 13 years and inclusive of interest.  

On February 25, 2022, we received $10.6 million in cash from Cabot (the "Cabot Payment") as a result of a change in control 
provision in the Supply Agreement (the "Change in Control"), which occurred as a result of the sale of Cabot by its parent, 
Cabot Corporation. Under the Change in Control, we received from Cabot full payment of all amounts outstanding under the 
Reclamation Reimbursement, payment of all unbilled amounts related to certain capital expenditures incurred by us through 
February 28, 2022 for specific use in manufacturing Furnace Products and payment of additional Reclamation Costs (the 
"Cabot Reclamation Costs"). Under the Reclamation Contract, we are obligated to remit payment for the Cabot Reclamation 
Costs to the third party operator of Marshall Mine within a specified timeframe. We will account for the Cabot Payment in its 
March 31, 2022 quarter and we do not anticipate any impacts to the Supply Agreement except as described above. 

As the owner of the Marshall Mine, we were required to post a surety bond to ensure performance of our reclamation activities. 
As of December 31, 2021, the amount outstanding under this surety bond was $16.6 million. For the obligations due under the 
Reclamation Contract, we were required to post collateral of $10.0 million. 

As of June 30, 2021 and December 31, 2021, we revised our estimate of future obligations owed for reclamation of the 
Marshall Mine primarily based on scope reductions related to future reclamation requirements. As a result, we reduced the 
Marshall Mine ARO by $1.9 million and $0.8 million as of June 30, 2021 and December 31, 2021, respectively, and recorded a 
corresponding gain on change in estimate in the aggregate of $2.7 million in the Consolidated Statements of Operations for the 
year ended December 31, 2021.

Settlement with Former Customer

On December 29, 2020, we and a former customer (the "Parties") reached a settlement (the "Settlement") on various litigation 
matters (the "Litigation Matters") that resulted in the former customer (the "Former Customer") agreeing to pay to us cash of 
$2.5 million (the "Settlement Amount"), which was received on January 27, 2021. This payment was in exchange for full 
dissolution of all claims and counterclaims that the two Parties have asserted or could have asserted against each other in the 
Litigation Matters, or which have arisen or may arise against each other but are presently unknown, arising out of or related to 
the Litigation Matters and related to any other of the Parties’ business dealings, conduct and/or transactions through the date of 
the Settlement, including all claims for damages, fees, costs, sanctions, or any other amounts due or to become due in 
connection with the foregoing. We applied the Settlement Amount cash proceeds to both an outstanding trade account 

27

receivable and a note receivable due from the Former Customer and recognized the excess cash received as a gain from the 
Settlement of $1.1 million, which is included as a reduction of operating expenses for the year ended December 31, 2020, See 
further discussion under "Results of Operations" under this Item 7.

Impact of COVID-19

In March 2020, the World Heath Organization declared COVID-19 a global pandemic. We follow the COVID-19 guidelines 
from the Centers for Disease Control concerning the health and safety of our personnel, including remote working for those that 
have the ability to do so, sequestered employees at our plant and other heath safety measures. Additionally, we have taken 
proactive and precautionary steps to ensure the safety of our employees, customers and suppliers, including frequent cleaning 
and disinfection of workspaces, property, plant and equipment, instituting social distancing measures and mandating remote 
working environments, where possible, for all employees. 

In response to the COVID-19 outbreak, in March 2020, the federal government passed the Coronavirus Aid, Relief, and 
Economic Security Act (the "CARES Act"). The CARES Act provided, among other things, the deferral of payroll tax 
payments for all payroll taxes incurred through December 31, 2020 and created the Paycheck Protection Program ("PPP"), 
which was sponsored and administered by the Small Business Administration ("SBA"). In June 2020, the Paycheck Protection 
Program Flexibility Act of 2020 (the "PPPFA") was signed into law and established the payment dates in the event that 
amounts borrowed under the PPP are not forgiven. See further discussion below of the loan made to us under the PPP under the 
section "PPP Loan" under this Item. 

We elected to defer payments of payroll taxes of $0.4 million for the periods allowed under the CARES Act, which allowed for 
a deferral of 50% of the total amount to December 31, 2021 and 50% of the total amount to December 31, 2022. As of 
December 31, 2021, we had repaid $0.2 million and will repay the outstanding balance by December 31, 2022.

For 2020, we incurred costs of $0.4 million related to sequestration of certain of our employees at our Red River plant. These 
costs included hazard pay, lodging and meal expenses for 30 days. For 2021, we did not incur similar costs.

Our customers may also be impacted by COVID-19 pandemic as we believe the utilization of energy has changed. We cannot 
predict the long-term impact on our customers and the subsequent impact on our business.

Components of Revenue, Expenses and Equity Method Investees 

The following briefly describes the components of revenues and expenses as presented in the Consolidated Statements of 
Operations. Descriptions of the revenue recognition policies are included in Note 1 to the Consolidated Financial Statements 
included in Item 8 of this Report. 

Revenues and cost of revenues

Consumables

We sell AC and products and other chemical-based technology products to a broad range of customers, including coal-fired 
utilities, industrials, water treatment plants and other diverse markets. Currently, our products mostly serve coal-fired utilities 
and other industrial boilers that allow the respective utilities to comply with the regulatory air emissions standards and water 
treatment plants to remove contaminants from the water. Additionally, we sell AC to Cabot and its customers through the 
Supply Agreement.

License royalties, related party 

We recognize license royalties under the M-45 License with Tinuum Group. License royalties from our M-45 Technology are 
based on a percentage of the per-ton, pre-tax margin, inclusive of depreciation expense and other allocable expenses, as defined 
in the M-45 License. Because Section 45 tax credits from the production and sale of RC are not available to be generated after 
2021 and both Tinuum Group and Tinuum Services significantly wound down their operations by the end of 2021, we do not 
expect to earn license royalties after 2021.

Other Operating Expenses

Payroll and benefits 

Payroll and benefits costs include personnel related fringe benefits, sales and administrative staff labor costs and stock 
compensation expenses. Payroll and benefits costs exclude direct labor included in Cost of revenues. 

28

Legal and professional fees 

Legal and professional costs include external legal, audit and consulting expenses.

General and administrative 

General and administrative costs include director fees and expenses, bad debt expense, research and development expense and 
other general costs of conducting business. Research and development costs, net of reimbursements from cost-sharing 
arrangements, are charged to expense in the period incurred and are reported in the General and administrative line item in the 
Consolidated Statements of Operations. 

Depreciation, amortization, depletion and accretion

Depreciation and amortization expense consists of depreciation expense related to property, plant and equipment and the 
amortization of long-lived intangible assets. Depletion and accretion expense consists of depletion expense related to the 
depletion of mine development costs and the accretion of mine reclamation liabilities.

Other Income (Expense), net

Earnings from equity method investments 

Earnings from equity method investments represent our share of earnings (losses) related to our equity method investments. 

We own a 42.5% equity interest and a 50% voting interest in Tinuum Group. Our equity method earnings in Tinuum Group are 
positively impacted when Tinuum Group obtains an investor in a RC facility and receives cash payments under either a lease 
arrangement or sales arrangement of the RC facility. If Tinuum Group operates a retained RC facility, the Company's equity 
method earnings are negatively impacted as operating retained RC facilities generate operating losses. However, we benefit on 
an after-tax basis if we are able to utilize tax credits associated with the production and sale of RC from operation of retained 
RC facilities by Tinuum Group. These benefits, if utilized, increase our consolidated net income as a result of a reduction in 
income tax expense. 

We own both a 50% equity and voting interest in Tinuum Services, which operates and maintains RC facilities under operating 
and maintenance agreements. The lessee/owner of an RC facility pays Tinuum Services, subject to certain limitations, the costs 
of operating and maintaining the RC facilities plus certain fees. Tinuum Services also arranges for the purchase and delivery of 
certain chemical additives under chemical agency agreements necessary for the production of RC. 

Other income (expense)

The remaining components of other income (expense) include interest income, interest expense and other miscellaneous items. 

Results of Operations

Presentation of Financial Results

For the year ended December 31, 2020, we have restated our "Revenues - Consumables" and "Cost of revenues, excluding 
depreciation and amortization" line items in our Consolidated Statement of Operations for the impact of previously reporting 
shipping and handling costs billed to our customers as a reduction to cost of revenue rather than as a component of consumables 
revenue. This restatement was a result of a reassessment of our accounting and presentation of shipping and handling costs 
billed to our customers under accounting principles generally accepted in the United States ("GAAP") in our Consolidated 
Statement of Operations for the year ended December 31, 2021. Historically, we have accounted for and presented shipping and 
handling costs billed to customers as a reduction of consumables cost of revenue rather than as a component of consumables 
revenue as required under Accounting Standards Codification 606 - Revenue from Contracts with Customers. Accordingly, we 
have restated both consumables revenues and consumable cost of revenues for the year ended December 31, 2020 by increasing 
the previously reported amounts by $5.8 million, respectively. 

For the year ended December 31, 2020, there was no impact of the restatement to previously reported amounts for gross 
margin, operating loss, loss before income taxes, net loss or loss per share. Further there was no impact of this error to the 
previously reported Consolidated Balance Sheet as of December 31, 2020 or the Consolidated Statement of Stockholders' 
Equity or Consolidated Statement of Cash Flows for the year ended December 31, 2020. See further discussion of this 
restatement in Note 2 to the Consolidated Financial Statements under Item 8 of this Report.

For comparison purposes, the following tables set forth our results of operations for the years presented in the Consolidated 
Financial Statements included in Item 8 of this Report. The year-to-year comparison of financial results is not necessarily 
indicative of financial results that may be achieved in future years. Our Annual Report on Form 10-K for the year ended 
December 31, 2020 includes a discussion and analysis of our financial condition and results of operations for the year ended 
December 31, 2019 in Item 7 of Part II, “Management’s Discussion and Analysis of Financial Condition and Results of 
Operations.”

Consumables revenues and consumables cost of revenues

For the years ended December 31, 2021 and 2020, consumables revenue increased year over year primarily due to higher 
product volumes, which comprised approximately $25.0 million of the total change in consumables revenues. Product volumes 
were higher in power generation primarily due to higher natural gas prices compared to the prior year, which contributed to 
increased utilization of coal-fired generation and increased demand for our products. In addition, product sales increased under 
the Supply Agreement from the prior year as we began product shipments under this agreement beginning in the fourth quarter 
of 2020. Total revenues also increased due to a favorable price impact of our products by approximately $1.0 million as well as 
favorable product mix impact on consumables revenue of approximately $4.1 million. Consumables revenue for 2021 also 
increased $0.9 million related to an increase in shipping and handling costs billed to our customers, driven by increases in 
volumes and costs to ship our products.

Our gross margin, exclusive of depreciation and amortization, increased for the year ended December 31, 2021 compared to 
2020 primarily due to the higher product volumes, which resulted in lower fixed costs per pound of product sold. Additionally, 
gross margin was positively impacted by product price increases. Offsetting these improvements for the year ended 
December 31, 2021, gross margin was negatively impacted by having to supplement the Red River production of our AC 
product, due to higher customer demand related to requirements-based contracts, with AC product purchases from third party 
suppliers at higher costs per pound. We expect to continue to purchase inventory from third party suppliers in 2022 due to 
ongoing increased demand for our products and Red River Plant capacity impacted by customer and product mix.

Consumables revenue is affected by electricity demand, driven by seasonal weather and related power generation needs, as well 
as competitor prices related to alternative power generation sources such as natural gas. According to data provided by the  U.S. 
Energy Information Administration, for the year ended December 31, 2021, power generation from coal-fired power dispatch 
was up approximately 18.0% compared to the corresponding period in 2020. Additionally, there was an increase in total power 
generation from all sources of approximately 3.1% in 2021 compared to the corresponding period in 2020. 

For 2022, and based on current market estimates and the expected benefits from the Supply Agreement, we believe that both 
consumables revenue and volumes will increase compared to 2021. We expect that consumables revenues and gross margin 
will be positively impacted by price increases announced in 2021 and our efforts to improve product mix to higher margin 
products through changes in our customer base. We anticipate that the product price increases will also help offset the increase 

30

 
 
 
 
 
 
 
 
in operating costs from purchasing inventory from third party suppliers, as well as expected increases in pricing related to 
certain additives necessary for our manufacturing operations.

License royalties, related party 

License royalties increased in 2021 compared to 2020 primarily due to an increase in the royalty rate per ton. This increase was 
primarily a result of an increase year over year in rent revenues generated from RC facilities even though the tonnage produced 
remained relatively flat. The tons of RC produced from RC produced using the M-45 Technology under the M-45 License were 
49.3 million and 49.4 million for the year ends December 31, 2021 and 2020, respectively. 

As a result of the Section 45 tax credit period ending as of December 31, 2021, both Tinuum Group and Tinuum Services 
ceased operations and, as such, we do not expect to earn M-45 License royalties after December 31, 2021.

Other cost of revenues

For the year ended December 31, 2020, we recognized a credit of $0.6 million to Other cost of revenues related to the 
Settlement with the Former Customer. See further discussion below of the reversal of an allowance on a note receivable due 
from the Former Customer in this section under the caption "General and administrative." 

Additional information related to revenue concentrations and contributions by class and reportable segment is included in the

Payroll and benefits 

Payroll and benefits expenses increased year over year primarily due to expenses of $1.1 million related to the agreements with 
our executive officers and certain other key employees executed in June 2021 ("Retention Agreements") as well as $1.3 million 
related to an increase in incentive expense for the year ended December 31, 2021 compared to 2020. These increases were 
offset by a decrease in expenses taken during the year ended December 31, 2020 of $1.4 million associated with the resignation 
of a former executive officer. Additionally, payroll expense decreased by approximately $0.5 million due to a decrease in 
headcount. 

Legal and professional fees

Legal and professional fees increased year over year primarily due to an increase in legal and consulting fees of $0.9 million 
and $1.2 million, respectively, related to our continuing evaluation of strategic alternatives. Offsetting these increases was $0.9 
million related to a reduction in outsourced shared service costs, which included legal and general consulting contractors, and 
$0.5 million in outsourced IT costs specific to the completion of the integration of Carbon Solutions in 2020.

General and administrative 

General and administrative expenses decreased year over year primarily due to decreases in product development expenses of 
approximately $0.6 million related to the Supply Agreement, costs incurred due to the sequestration of certain of our employees 
at the Red River Plant in 2020 of approximately $0.4 million, rent and occupancy related expenses of $0.3 million and other 
general and administrative expenses, including recruiting, travel and licenses and fees of approximately $0.7 million. 

Offsetting the net decrease in general and administrative expenses year over year was the offset to general and administrative 
expenses in 2020 from the reversal of an allowance on a note receivable from the Former Customer of $0.4 million. See further 
discussion below in this section under the caption "Gain on settlement." Further increases year over year included an increase in 
insurance premiums of approximately $0.4 million.

Depreciation, amortization, depletion and accretion 

Depreciation and amortization expense decreased year over year primarily due to lower absorption from the drawdown of 
inventory, partially offset by increase in sales volumes for 2021, resulting in a decrease of depreciation expense of $0.2 million. 
Further, depreciation and amortization expense decreased by approximately $1.1 million related to a lower depreciable base for 
2021 compared to 2020 as a result of an impairment charge recorded in the second quarter of 2020 which reduced the carrying 
value of our property, plant and equipment. Offsetting these decreases was an increase in accretion expense of $0.6 million 
related to the Marshall Mine ARO and an increase in depletion expense of $0.2 million due to increased production volume at 
the Five Forks Mine.

Gain on change in estimate, asset retirement obligation

As previously discussed under this Item, for the year ended December 31, 2021, we recorded a gain on change in estimate of 
$2.7 million related to a reduction in scope of our estimated future reclamation efforts of the Marshall Mine.

Impairment of long-lived assets

As of June 30, 2020, we recorded an impairment charge of $26.1 million, which is included in the Statement of Operations for 
the year ended December 31, 2020 and was solely attributable to our APT segment. This impairment charge was necessitated 
by an analysis of the carrying values of our APT segment's long-lived assets and certain other long-lived assets (the "Asset 
Group"), which are comprised of our manufacturing plant and related assets and our lignite mine assets, to their respective fair 
values.

Gain on settlement

In connection with the Settlement discussed above, the Former Customer paid us the cash Settlement Amount of $2.5 million 
on January 27, 2021 in exchange for a full release of claims in the Litigation Matters. As a result of the Settlement, we 
recognized a gain of $1.1 million for the year ended December 31, 2020.

* Calculation not meaningful

For the year ended December 31, 2021, we recognized $61.8 million in equity earnings from Tinuum Group compared to our 
proportionate share of Tinuum Group's net income of $40.1 million for the year. The difference between our pro-rata share of 
Tinuum Group's net income and our earnings from Tinuum Group equity method investment as reported on the Consolidated 
Statements of Operations is the result of cumulative distributions received from Tinuum Group being in excess of the carrying 
value of the investment, and therefore we recognize such excess distributions as equity method earnings in the period the 
distributions occur.

For the year ended December 31, 2020, we recognized $24.4 million in equity earnings from Tinuum Group, which was equal 
to our proportionate share of Tinuum Group's net income for the year.

As of December 31, 2021, we concluded the carrying amount of our investment in Tinuum Services was not fully recoverable 
due to the remaining expected future cash distributions to be received as Tinuum Services shutters its operations in 2022 as a 
result of the expiration of the Section 45 tax credit period as of December 31, 2021. As a result, we wrote-down our investment 
in the amount of $0.7 million, which is included in the "Earnings from equity method investments" line item in the 
Consolidated Statement of Operations for the year ended December 31, 2021. 

See further discussion of year over year changes in Earnings from Equity Investments in "Business Segments" under this Item. 
Additional information related to equity method investments is included in Note 8 to the Consolidated Financial Statements 
included in Item 8 of this Report.

Tinuum Group's audited consolidated financial statements as of December 31, 2021 and 2020 and for the years then ended are 
included in Item 15 - "Exhibits and Financial Statement Schedules" ("Item 15") of this Report. 

33

 
 
 
 
 
 
 
 
 
 
 
 
Gain on extinguishment of debt

On July 27, 2021, we received formal notification in the form of a letter dated July 19, 2021 from Bank of Oklahoma ("BOK") 
that the SBA approved our PPP Loan forgiveness application for the PPP Loan in the amount of $3.3 million (including accrued 
interest). For the year ended December 31, 2021, we recorded a gain on extinguishment of the PPP Loan in the amount of $3.3 
million in the Consolidated Statement of Operations, which is included as a component of "Other income (expense)."

Tax Credits and Obligations

Historically, we have earned Section 45 tax credits that may be available for future benefit related to the production of RC from 
the operation of RC facilities in which we have held both direct ownership and indirect ownership through Tinuum's direct 
ownership. We refer to these RC facilities as "retained facilities." The Section 45 tax credit period ended December 31, 2021 
and we will not earn Section 45 tax credits beyond this date. As of December 31, 2021, we had approximately $86.1 million in 
Section 45 tax carryforwards.

In the hypothetical event of an ownership change, as defined by IRC Section 382, utilization of general business credits 
("GBC's") generated prior to the change would be subject to an annual limitation imposed by IRC Section 383 for GBC's. The 
results of a recent analysis indicated that we had not experienced an ownership change as of December 31, 2021, as defined by 
IRC Section 382. Such analysis for the period from January 1, 2022 through the date of this Report has not been completed. 
Therefore, it is possible that we experienced an ownership change between January 1, 2022 and the date of the filing of this 
Report, thus subjecting our GBC carryforwards to limitation. 

Interest expense 

Interest expense decreased year over year by $2.4 million primarily due to principal payments made in 2021 on a senior term 
loan (the "Senior Term Loan") that resulted in lower coupon interest expense of $1.5 million. Interest expense for debt discount 
and debt issuance costs related to the Senior Term Loan also decreased by $0.5 million pursuant to the decrease in the Senior 
Term Loan principal. On June 1, 2021 and prior to the Senior Term Loan's maturity date, we paid the remaining principal 
balance of the Senior Term Loan and all remaining accrued interest through this date.

The remaining decrease in interest expense year over year related to lower interest expense ("Section 453A interest") related to 
IRS section 453A ("Section 453A"), which decreased by $0.3 million primarily due to a decrease in Tinuum Group's the tax 
liability year over year associated with RC facilities in which Tinuum Group recognized as installment sales for tax purposes.

The following table shows the balance of the tax liability that has been deferred and the applicable interest rate used to calculate 
the 453A interest liability:

(1) Represents the approximate tax effected liability utilizing the federal tax rate in effect for the applicable year ended related to the deferred 
gain on installment sales, which was approximately zero as of December 31, 2021.   

Income tax expense 

For the year ended December 31, 2021, our reported income tax expense was $15.7 million and was based on an effective rate 
of 21%. While the U.S. statutory federal income tax rate (the "Federal Rate") was also 21%, our effective tax rate was primarily  
increased for state income tax expense, net of federal benefit, and decreased from a reduction in the valuation allowance on our 
deferred tax assets.

For the year ended December 31, 2020, our reported income tax expense of $6.5 million and was based on an inverse effective 
rate of 47%, which differed from the Federal Rate of 21% due to primarily an increase in the valuation allowance on our 
deferred tax assets. This increase in the valuation allowance resulted in income tax expense rather than expected income tax 
benefit based on the pretax loss.

Accounting for income taxes requires that companies assess whether a valuation allowance should be recorded against their 
deferred tax asset based on an assessment of the amount of the deferred tax asset that is “more likely than not” to be realized. 

34

Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount that is more likely than not to 
be realized. 

We assess a valuation allowance recorded against deferred tax assets at each reporting date. The determination of whether a 
valuation allowance for deferred tax assets is appropriate requires the evaluation of positive and negative evidence that can be 
objectively verified. Consideration must be given to all sources of taxable income available to realize the deferred tax asset, 
including, as applicable, the future reversal of existing temporary differences, future taxable income forecasts exclusive of the 
reversal of temporary differences and carryforwards, taxable income in carryback years and tax planning strategies. In 
estimating taxes, we assess the relative merits and risks of the appropriate tax treatment of transactions taking into account 
statutory, judicial, and regulatory guidance.

As of December 31, 2021, we concluded it is more likely than not we will not generate sufficient taxable income within the 
allowable  carryforward  periods  to  realize  any  of  our  net  deferred  tax  assets,  and  fully  reserved  for  such  assets  as  of 
December 31, 2021. In reaching this conclusion, we primarily considered forecasts of future taxable losses. As of December 31, 
2021 and 2020, we had a valuation allowance of $87.5 million and $88.8 million, respectively, on our deferred tax assets.

The ability to recognize the remaining deferred tax assets that continue to be subject to a valuation allowance is evaluated on a 
quarterly basis to determine if there are any significant events that would affect the ability to utilize those deferred tax assets. 
Our  estimate  of  future  taxable  income  or  losses  is  based  on  internal  projections  that  consider  historical  performance, 
assumptions on future performance and external data. If events are identified that affect our ability to utilize our deferred tax 
assets,  or  if  additional  deferred  tax  assets  are  generated,  we  update  our  analysis  to  determine  if  an  increase  to  a  valuation 
allowance is required. Such an increase could have a material adverse effect on our financial condition and results of operations. 
Conversely,  better  than  expected  results  and  continued  positive  results  and  trends  could  result  in  a  decrease  to  a  valuation 
allowance, and any such decreases could have a material positive effect on our financial condition and results of operations. 

See additional discussion in Note 18 of the Consolidated Financial Statements included in Item 8 of this Report.

Non-GAAP Financial Measures

To supplement our financial information presented in accordance with GAAP, we are providing non-GAAP measures of certain 
financial performance. These non-GAAP measures include Consolidated EBITDA, Consolidated Adjusted EBITDA, RC 
Segment EBITDA, RC Segment Adjusted EBITDA, APT Segment EBITDA and APT Segment Adjusted EBITDA. We have 
included non-GAAP measures because management believes that they help to facilitate period to period comparisons of our 
operating results. We believe the non-GAAP measures provide useful information to both management and users of the 
financial statements by excluding certain expenses, gains and losses that may not be indicative of core operating results and 
business outlook. Management uses these non-GAAP measures in evaluating the performance of our business.

These non-GAAP measures are not in accordance with, or an alternative to, measures prepared in accordance with GAAP and 
may be different from non-GAAP measures used by other companies. In addition, these non-GAAP measures are not based on 
any comprehensive set of accounting rules or principles. These measures should only be used to evaluate our results of 
operations in conjunction with the corresponding GAAP measures.

We define Consolidated EBITDA as net income adjusted for the impact of the following items that are either non-cash or that 
we  do  not  consider  representative  of  our  ongoing  operating  performance:  depreciation,  amortization,  depletion,  accretion, 
amortization of upfront customer consideration that was recorded as a component of the Marshall Mine Acquisition ("Upfront 
Customer  Consideration"),  interest  expense,  net  and  income  tax  expense.  We  define  Consolidated  Adjusted  EBITDA  as 
Consolidated EBITDA, reduced by the non-cash impacts of equity earnings from equity method investments, gain on change in 
estimate of asset retirement obligations, gain on extinguishment of debt and gain on customer settlement, and increased by cash 
distributions  from  equity  method  investments  and  impairment  of  long-lived  assets.  Because  Consolidated  Adjusted  EBITDA 
omits certain non-cash items, we believe that the measure is less susceptible to variances that affect our operating performance.

We define APT Segment EBITDA (loss) as APT Segment operating loss adjusted for the impact of the following items that are 
either non-cash or that we do not consider representative of our ongoing operating performance: depreciation, amortization, 
depletion, accretion, amortization of Upfront Customer Consideration and interest expense, net. We define APT Segment 
Adjusted EBITDA (loss) as APT Segment EBITDA (loss), reduced by gain on customer settlement, gain on change in estimate 
of asset retirement obligation, gain on extinguishment of debt and gain on customer settlement, and increased by impairment of 
long-lived assets. 

We define RC Segment EBITDA as RC Segment operating income adjusted for the impact of the following items that are either 
non-cash or that we do not consider representative of our ongoing operating performance: depreciation, amortization, depletion, 
accretion and interest expense. We define RC Segment Adjusted EBITDA as RC Segment EBITDA, reduced by the non-cash 
impact of equity earnings from equity method investments and gain on extinguishment of debt, and increased by cash 
distributions from equity method investments.

When used in conjunction with GAAP financial measures, we believe these non-GAAP measures are supplemental measures of 
operating performance that explain our operating performance for our period to period comparisons and against our 
competitors' performance. Generally, we believe these non-GAAP measures are less susceptible to variances that affect our 
operating performance results. 

With the exception of extinguishment of debt, gain on change in estimate, asset retirement obligation, impairment on long-lived 
assets and gain on settlement, the adjustments to Consolidated Adjusted EBITDA and APT Segment Adjusted EBITDA in 
future periods are generally expected to be similar. These non-GAAP measures have limitations as analytical tools and should 
not be considered in isolation or as a substitute for analyzing our results as reported under GAAP.

The accounting policies of the operating segments are the same as those described in the summary of significant 
accounting policies except as described below. 

Segment revenues include equity method earnings and losses from our equity method investments.

Segment operating income (loss) includes segment revenues, gains related to sales of equity method investments and 
allocation of certain "Corporate general and administrative expenses," which include Payroll and benefits, Legal and 
professional fees, General and administrative, and Depreciation, amortization, depletion and accretion.  

RC segment operating income includes interest expense directly attributable to the RC segment.

For 2021, equity earnings from Tinuum Group were positively impacted by an increase in overall coal-fired power generation 
demand and higher production volume from coal-fired sources, which was driven by higher prices related to alternative power 
generation sources such as natural gas. Also, this increase was driven by higher RC facility count for the majority of 2021 
compared to 2020. Further, for the year ended December 31, 2020, we recognized equity earnings from Tinuum Group equal to 

38

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
our proportionate share of Tinuum Group's net income for the period, which was less than cash distributions received for the 
same period.

In the fourth quarter of 2020, Tinuum Group recorded an impairment charge of $3.0 million on certain of its assets located at 
RC facilities and a retention accrual related to the wind down of its operations upon the expected expiration of Section 45 on 
December 31, 2021.

RC earnings related to M-45 license royalties increased from 2021 to 2020 as a result of an increase in the royalty rate per ton 
year over year offset by a reduction in RC facilities subject to the M-45 License due to the expected expiration of Section 45 on 
December 31, 2021.

Equity earnings from Tinuum Services increased by $0.4 million in 2021 compared to 2020 primarily as a result of recording an 
impairment charge of $2.9 million for year ended December 31, 2020 as well as an increase in tonnage for the RC facilities that 
Tinuum Services operated in 2021 compared to 2020. As of December 31, 2021 and 2020, Tinuum Services provided operating 
and maintenance services to zero and 22 RC facilities, respectively. Tinuum Services derived earnings from both fixed-fee 
arrangements as well as fees that are tied to actual RC production, as determined by the specific RC facility operating and 
maintenance agreement.

As discussed above, as of December 31, 2021, the Company reduced its investment in Tinuum Services in the amount of 
$0.7 million, which is included in the "Earnings from equity method investments" line item in the Consolidated Statement of 
Operations for the year ended December 31, 2021. 

Outlook

As a result of the expiration of the ability to generate Section 45 tax credits after December 31, 2021, both Tinuum Group and 
Tinuum Services ceased operations and are in reclamation of their respective businesses. The loss of equity earnings, 
distributions and M-45 Royalties beginning in 2022 will have a material adverse effect on our financial condition and 
consolidated operating results compared to historical periods.

APT segment operating income increased during the year ended December 31, 2021 compared to 2020 primarily due to the 
Impairment Charge of $26.1 million recorded for the year end December 31, 2020. Further, for the year ended December 31, 
2021, consumable revenues and associated gross margin increased, driven by an increase in volume year over year, specifically 
related to the Supply Agreement, as well as an increase in demand for our products by our current customer base and from new 
customers.

During the year ended December 31, 2020, we incurred costs of $0.4 million related to sequestration of certain of our 
employees at our Red River plant. These costs included hazardous pay, lodging expense and other related costs for 60 days.

39

 
 
 
 
 
 
 
 
 
 
Outlook

Based on current market estimates, we believe that the APT segment will continue to be affected, both positively and 
negatively, by power generation and the pricing of other sources, including natural gas and renewable energy, as well as 
weather throughout the U.S. In 2022, we expect demand from our current customers to be consistent with 2021 based on 
current market trends. Further, we see opportunities and are continuing to pursue diverse markets for our purification products 
outside of coal-fire power generation, including industrial application, water treatment plants and other end markets.

Liquidity and Capital Resources 

Current Resources and Factors Affecting Our Liquidity

As of December 31, 2021, our principal future sources of liquidity include:

•
•

$88.8 million of cash, cash equivalents and restricted cash; and
operations of the APT segment

For the year ended December 31, 2021, our principal uses of liquidity included:

•

•

our business operating expenses, including capital expenditures, reclamation costs, federal and state tax payments and 
cash severance payments; and 
payment of debt principal and interest.

During 2021, our liquidity position was positively affected primarily from cash distributions from Tinuum Group and Tinuum 
Services, royalty payments from Tinuum Group and borrowing availability under our line of credit with a bank ("Line of 
Credit"). Due to the expiration of the Section 45 tax period as of December 31, 2021 and the resultant wind down of Tinuum 
Group's and Tinuum Services' operations at the end of 2021, distributions from Tinuum Group will no longer be a material 
source of liquidity after 2021. Our line of credit expired on December 31, 2021.

Our ability to continue to generate sufficient cash flow required to meet ongoing operational needs and obligations, and make 
potential future dividend payments and share repurchases depends upon several factors. These include: (1) executing on our 
contracts and initiatives; (2) increasing our share of the market for APT consumables, including expanding our overall AC 
business into additional adjacent markets and improving our customer and product mix; and (3) receiving final, expected M-45 
License royalty payments from Tinuum Group and distributions from Tinuum Group and Tinuum Services in 2022. 

For 2022 and beyond, our primary sources of liquidity are expected to be from cash on hand and through the ongoing 
operations of our APT segment. We believe our existing operations and related contract volumes will continue to provide 
operating cost efficiencies of the Red River Plant, providing additional sources of operating cash flows in the future. Full and 
partial reimbursements on capital expenditures from Cabot will offset our uses of investing cash flows. As discussed above, on 
February 25, 2022, we received the Cabot Payment in the amount of $10.6 million, which provides a source of cash for us in 
2022. 

Tinuum Group and Tinuum Services Distributions

The following table summarizes the cash distributions from our equity method investments, which most significantly affected 
our consolidated cash flow results, for the years ended December 31, 2021 and 2020:

Cash distributions from Tinuum Group for 2021 increased by $11.9 million compared to 2020 primarily due to higher 
production volume driven by high competitor prices related to alternative power generation sources such as natural gas. Also, 
this increase was driven by higher average RC facility count for the year ended December 31, 2021 compared to 2020.

Both Tinuum Group and Tinuum Services ceased their operations as of December 31, 2021 due to the expiration of the Section 
45 tax credit period as of December 31, 2021. As such, our distributions from our RC segment will substantially cease as of 
December 31, 2021.

During the first half of 2022, we expect to receive final cash distributions from Tinuum Group and Tinuum Services in the 
range of $4.0 to $5.0 million.

PPP Loan

On April 20, 2020, we entered into the PPP Loan under the PPP, evidenced by a promissory note, with BOK providing for $3.3 
million in proceeds, which was funded on April 21, 2020. The PPP Loan had a maturity date of April 21, 2022. The PPP Loan 

41

 
 
principal was eligible for forgiveness subject to the terms of the PPP and approval by the SBA. The interest rate on the PPP 
Loan was 1.00%. The PPP Loan was unsecured and contains customary events of default relating to, among other things, 
payment defaults, making materially false and misleading representations to the SBA or BOK, or breaching the terms of the 
PPP Loan. The occurrence of an event of default could result in the repayment of all amounts outstanding, collection of all 
amounts owing from us, or filing suit and obtaining judgment against us.

On July 27, 2021, we received formal notification in the form of a letter dated July 19, 2021 from BOK that the SBA approved 
the forgiveness of our PPP Loan forgiveness application for the PPP Loan in the amount of $3.3 million (including accrued 
interest). For the year ended December 31, 2021, the Company recorded a gain on extinguishment of the PPP Loan in the 
amount of $3.3 million in the Consolidated Statements of Operations, which is included as a component of "Other income 
(expense)."

Restricted Cash

As of December 31, 2021, we had long-term restricted cash of $10.0 million as required under the Surety Agreement related to 
the Reclamation Contract. 

Senior Term Loan

On December 7, 2018, we and ADA-ES, Inc. ("ADA"), a wholly-owned subsidiary, and certain other subsidiaries of the 
Company as guarantors, The Bank of New York Mellon as administrative agent, and Apollo Credit Strategies Master Fund Ltd 
and Apollo A-N Credit Fund (Delaware) L.P., affiliates of a beneficial owner of greater than five percent of our common stock 
and a related party, entered into the Senior Term Loan in the amount of $70.0 million, less original issue discount of $2.1 
million. Proceeds from the Senior Term Loan were used to fund the acquisition of Carbon Solutions. We also paid debt 
issuance costs of $2.0 million related to the Senior Term Loan. The Senior Term Loan bore interest at a rate equal to 3-month 
LIBOR (subject to a 1.5% floor) + 4.75% per annum, which was adjusted quarterly to the current 3-month LIBOR rate, and 
interest was payable quarterly in arrears. The Senior Term Loan was secured by substantially all the assets of the Company, 
including the cash flows from the Tinuum Entities, but excluding our equity interests in the Tinuum entities.

On June 1, 2021 and prior to the Senior Term Loan's maturity date, we paid the remaining principal outstanding on the Senior 
Term Loan and all remaining accrued interest through this date. We did not incur any prepayment fees associated with the early 
pay-off.

Stock Repurchases and Dividends

In November 2018, our Board authorized us to purchase up to $20.0 million of our outstanding common stock under a stock 
repurchase program (the "Stock Repurchase Program"), which was to remain in effect until December 31, 2019 unless 
otherwise modified by the Board. As of November 2019, $2.9 million remained outstanding related to Stock Repurchase 
Program. In November 2019, the Board authorized an incremental $7.1 million to the Stock Repurchase Program and provided 
that it will remain in effect until all amounts are utilized or it is otherwise modified by the Board. We did not make any stock 
repurchases during the year ended December 31, 2021.

During the year ended December 31, 2021, we did not pay quarterly cash dividends to stockholders. We paid our most recent 
dividend in March 2020 of $0.25 per share.   

42

Line of Credit

In September 2013, ADA, as borrower, ADES, as guarantor, entered into the Line of Credit with a bank for an aggregate 
principal amount of $10.0 million that was secured by certain amounts due to us from certain Tinuum Group RC leases. The 
Line of Credit was amended 16 times from the period from December 2, 2013 through March 23, 2021, which included a 
reduction in the principal amount to $5.0 million in September 2018. The Line of Credit expired on December 31, 2021. 

Cash Flows

Cash, cash equivalents and restricted cash increased from $35.9 million as of December 31, 2020 to $88.8 million as of 
December 31, 2021, an increase of $52.8 million. The following table summarizes our cash flows for the years ended 
December 31, 2021 and 2020, respectively:

Cash flows provided by operating activities for the year ended December 31, 2021 decreased by $28.0 million compared to the 
year ended December 31, 2020 and the net decrease was primarily due to the following: (1) a decrease in Distributions from 
equity method investees, return on investment of $39.5 million year over year; (2) an increase in Earnings from equity method 
investments of $37.7 million year over year; (3)Impairment of long-lived assets of $26.1 million recorded in 2020; and (4) Gain 
on extinguishment of debt of $3.3 million recorded in 2021. Offsetting the net decrease in cash flows provided by operating 
activities year over year was a net change in net income of $80.7 million year over year as a result of net loss recognized for the 
year ended December 31, 2020.

Cash flows from investing activities

Cash flows provided by investing activities for the year ended December 31, 2021 were $44.4 million compared to cash flows 
used in investing activities of $7.5 million for the year ended December 31, 2020. This net increase in cash flows provided by 
investing activities was primarily due to increases in distributions from equity earnings in excess of cumulative earnings of 
$51.1 million year over year as well as proceeds from the sale of property and equipment in 2021.

Cash flows from financing activities

Cash flows used in financing activities for the year ended December 31, 2021 decreased by $10.2 million compared to the year 
ended December 31, 2020 primarily due to lower principal payments on the Senior Term Loan of $8.0 million. Also 
contributing to the decrease was a decrease year over year in dividends paid and shares repurchased of $4.9 million and $0.2 
million, respectively, and a reduction in repurchases of shares of our common stock to satisfy tax withholdings of $0.3 million. 
Offsetting the net decrease year over year was $3.3 million of cash proceeds received in 2021 from the forgiveness of the PPP 
Loan.

Material Cash Requirements

For 2022, we expect to spend $13.0 million in capital expenditures compared to $7.6 million incurred in 2021. This increase is 
primarily the result of forecasted improvements to the plant, which are estimated to be $7.0 million, product specific capital 
expenditures related to the Supply Agreement, which are estimated to be $1.0 million and routine, scheduled maintenance 
improvements.

As of June 30, 2021, we entered into the Retention Agreements for the purpose of retaining officers and key employees in order 
to maintain our current business operations, while we pursue and execute on our strategic initiatives. The total amount due at 
time of payment pursuant to the Retention Agreements is $2.0 million, which we expect to pay in 2022.

We intend to fund the remaining portion of the Reclamation Costs from cash on hand as well as cash generated from the Supply 
Agreement. We believe that as reclamation activities proceed and the related bonded amounts required under the Surety 
Agreement are able to be reduced, there may be an opportunity to further reduce the collateral requirement. On a normalized 
basis, our annual capital expenditures, exclusive of any capital specifically procured for Cabot under the Supply Agreement or 
capital for major improvements to the plant, are expected to average approximately $5.0 million. 

We expect that our cash on hand as of December 31, 2021 will provide sufficient liquidity to fund operations for the next 12 
months.

(1) Includes payments due under a capped fee contract with a third-party mining operator for reclamation of the Marshall Mine (the "Marshall 
Mine ARO"). Payments on this contract are due through approximately 2031. Reclamation costs related to the Marshall Mine ARO are based 
on a stated fee by month structure based on the initial estimate of the total costs of reclamation, which provides for certain contingencies that 
could increase or decrease the reclamation fee over time. The timing and amount of future payments may change from original estimates, and 
the Company assesses changes in estimated future amounts on a quarterly basis. 

The table above also excludes our asset retirement obligation ("ARO") related to reclamation of the Five Forks Mine (the "Five 
Forks ARO"). As of December 31, 2021, our consolidated balance sheet reflects a liability of $3.6 million for the Five Forks 
ARO. The Five Forks Mine ARO was recorded at fair value. The timing and amount of payments to satisfy the Five Forks ARO 
are uncertain and are based on numerous factors including, but not limited to, the Five Forks Mine expected closure date.

We had no outstanding letters of credit as of December 31, 2021. We expect that our cash on hand as of December 31, 2021 
will provide sufficient liquidity to fund operations for the next 12 months.

As of December 31, 2021, we had outstanding surety bonds of $24.1 million related to performance requirements under 
reclamation contracts associated with both the Five Forks Mine and the Marshall Mine. As of December 31, 2021, we had 
restricted cash of $10.0 million securing the Surety Agreement. We expect that the obligations secured by these surety bonds 
will be performed in the ordinary course of business and in accordance with the applicable contractual terms. To the extent that 
the obligations are performed, the related surety bonds should be released, and we should not have any continuing obligations. 
However, in the event any surety bond is called, our indemnity obligations could require us to reimburse the issuer of the surety 
bond.

Critical Accounting Policies and Estimates

Our significant accounting policies are discussed in Note 1 to the Consolidated Financial Statements included in Item 8 of this 
Report. In presenting our financial statements in conformity with GAAP, we are required to make estimates and assumptions 
that affect the amounts reported therein. Several of the estimates and assumptions we are required to make relate to matters that 
are inherently uncertain as they pertain to future events. Our estimates are based on historical experience and other assumptions 
believed to be reasonable under the circumstances, and we evaluate these estimates on an ongoing basis. Actual results may 
differ from these estimates under different assumptions or conditions.

We believe that the accounting estimates discussed below are critical to understanding our historical and future performance, as 
these estimates relate to the more significant areas involving management’s judgments and estimates.

Business Combinations, including asset acquisitions

We apply the acquisition method to acquisitions of both businesses and assets and allocate the purchase price to the tangible 
and intangible assets acquired and liabilities assumed based on their estimated fair values at the acquisition date. The purchase 
price allocation process requires us to make significant estimates and assumptions with respect to assets acquired and liabilities 
assumed. We believe the assumptions and estimates we make are reasonable, they are based in part on historical experience, 
market conditions and information obtained from management of the acquired company or group of assets and are inherently 
uncertain. 

Examples of critical estimates in valuing certain of long-lived assets, including intangible assets, we have acquired or may 
acquire in the future include but are not limited to:

•

•

future expected cash flows from revenues;

historical and expected customer attrition rates and anticipated growth in revenues from acquired customers;

45

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
•

•

•

the acquired company’s developed technology as well as assumptions about the period of time the acquired developed 
technology will continue to be used in the combined company's product portfolio;

the expected use and useful lives of the acquired assets; and

valuation methods and discount rates used in estimating the values of the assets acquired and liabilities assumed.

In regard to the Marshall Mine Acquisition, which we accounted for as an asset acquisition, we recorded the fair value of 
assumed assets, which included property, plant and equipment and spare parts and assumed liabilities. In addition, we recorded 
other assets, including Upfront Customer Consideration and the Cabot Receivable, and a liability for the Marshall Mine ARO.   

Carrying value of long-lived assets and intangibles

We review and evaluate our long-lived assets and intangibles for impairment at least annually, or more frequently when events 
or changes in circumstances indicate that the related carrying amounts may not be recoverable. An impairment loss is measured 
and recorded for long-lived assets and intangibles based on the excess of their carrying amounts over their estimated fair values.  
Fair value is typically determined through the use of an income approach utilizing estimates of discounted pretax future cash 
flows or a market approach utilizing recent transaction activity for comparable assets. 

Asset Retirement Obligations 

Accounting for AROs requires us to make estimates of future costs unique to a specific mining operation that we will incur to 
complete the reclamation and remediation work required to comply with existing laws and regulations. Any such changes in 
future costs, the timing of reclamation activities, scope or the exclusion of certain costs not considered reclamation and 
remediation costs could materially impact the amounts charged to earnings for reclamation and remediation. Additionally, 
future changes to environmental laws and regulations could increase the scope of reclamation and remediation work required.

Five Forks Mine ARO - Reclamation costs related to the Five Forks Mine ARO are allocated to expense over the life of the 
related mine assets and are periodically adjusted to reflect changes in the estimated present value resulting from the passage of 
time and revisions to the estimates of either the timing or amount of the reclamation costs. Remediation costs for the Five Forks 
Mine are accrued based on management’s best estimate of the costs expected to be incurred. Such cost estimates may include 
ongoing care, maintenance and monitoring costs. Reclamation obligations are based on the timing of estimated spending for an 
existing environmental disturbance. We review, on at least an annual basis, the future expected costs and the timing of such 
costs for the Five Forks Mine ARO.

Marshall Mine ARO - Reclamation costs related to the Marshall Mine are based on a capped fee structure for a significant 
portion of the ARO liability based on the initial estimate of the total costs of reclamation, which provides for certain 
contingencies that could increase or decrease the reclamation fee based on the reclamation agreement executed between us and 
the Marshall Mine operator. The timing of payments may vary, and in valuing the the Marshall Mine  ARO, we account for 
these timing differences, as well as changes in actual reclamation costs, on a quarterly basis.

Income Taxes

We account for income taxes under the asset and liability method, which requires judgment in determining income tax expense 
and the related balance sheet amounts. This includes estimating and analyzing historical and projected future operating results, 
the reversal of taxable temporary differences, tax planning strategies, and the ultimate outcome of uncertain income tax 
positions. Actual income taxes paid may vary from estimates depending on changes in income tax laws, actual results of 
operations, state apportionment and, if applicable, final audits of tax returns by taxing authorities. Tax assessments may arise 
several years after tax returns have been filed. Changes in the estimates and assumptions used for calculating income tax 
expense and potential differences in actual results from estimates could have a material impact on our results of operations and 
financial condition.

We recognize deferred tax assets to the extent that we believe these assets are more likely than not to be realized. In making 
such a determination, we consider all available positive and negative evidence, including future reversals of existing taxable 
temporary differences, projected future taxable income, tax-planning strategies and results of recent operations. 

We establish a valuation allowance against our deferred tax assets when, based upon the weight of all available evidence, we 
believe it is more likely than not that some portion or all of the deferred tax assets will not be realized. In making this 
determination, we consider the relative impact of all of the available positive and negative evidence regarding future sources of 
taxable income and tax planning strategies. However, there could be a material impact to our effective tax rate if there is a 

46

significant change in our estimates of future taxable income. If and when our estimates change, or there is a change in the value 
of deferred tax assets or liabilities warranting the need to reassess the realizability of deferred tax assets, we adjust a valuation 
allowance through the provision for income taxes in the period in which this determination is made. Refer to Note 18 of our 
Consolidated Financial Statements included in Item 8 of this Report for additional information regarding our deferred tax assets 
and liabilities and related deferred income tax expense (benefit).

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of
Advanced Emissions Solutions, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Advanced Emissions Solutions, Inc. and subsidiaries (the 
"Company") as of December 31, 2021 and 2020, the related consolidated statements of operations, changes in stockholders’ 
equity and cash flows for the years then ended, and the related notes (collectively referred to as the consolidated financial 
statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the consolidated 
financial position of the Company as of December 31, 2021 and 2020, and the consolidated results of its operations and its cash 
flows for the years then ended, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express 
an opinion on the Company’s consolidated 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 consolidated 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 consolidated financial statements, 
whether due to error or fraud, and performing procedures to respond to those risks. Such procedures included examining, on a 
test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included 
evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall 
presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial 
statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or 
disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or 
complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated 
financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate 
opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Income Taxes – Realizability of Deferred Tax Assets

As described in Notes 1 and 18 to the consolidated financial statements, the Company recognizes deferred income taxes for the 
effects of temporary differences between the tax basis of an asset or liability and their reported amounts in the accompanying 
consolidated balance sheet. These temporary differences result in taxable or deductible amounts in future years. Valuation 
allowances are established, when necessary, to reduce deferred tax assets to the amount that is more likely than not to be 
realized. As of December 31, 2021, the Company concluded it is more likely than not that the Company will not generate 
sufficient taxable income within the applicable net operating loss and tax credit carry-forward periods to realize any of its net 
deferred tax assets, which resulted in a valuation allowance of $87.5 million.

50

We identified the realizability of deferred tax assets as a critical audit matter due to the Company’s tax structure and the 
significant judgments and estimates made by management to determine that sufficient taxable income will not be generated to 
realize a portion of deferred tax assets prior to expiration. This required a high degree of auditor judgment and an increased 
extent of effort when performing audit procedures to evaluate management’s estimates of taxable income prior to expiration.

The primary procedures we performed to address this critical audit matter included:

•

•

•

•

•

•

Recalculating the mathematical accuracy of management’s accounting for the previously described taxes, which 
included supporting calculations, schedules, and reconciliations.
Reading and evaluating management’s documentation of the accounting for income taxes, including their analysis of 
the valuation allowance. This includes relevant significant accounting policies, and information obtained by 
management from third party tax specialists which details management’s basis for the accounting and impact to the 
consolidated financial statements, inclusive of relevant positive and negative evidence available and utilized in 
performing the analysis.
Obtaining and evaluating the supporting tax analyses and documentation prepared by management as a framework and 
initial support for audit procedures. This includes gaining an understanding of the Company’s estimation process, the 
Company’s deferred tax calculations, which also integrates management’s analysis of valuation allowances, current tax 
expenses (benefits), and IRC Section 45 credits.
Consulting with internal tax specialists in evaluating management’s calculation of its provision for income taxes and 
that the significant judgments used were applied consistently with the tax code. 
Evaluating whether significant estimates and judgments used were consistent with past performance related to said 
estimates, the consistency of future forecasts and projections based on current operating and market conditions and 
future expectations, and that all were consistent with evidence obtained in procedures performed in other areas of the 
audit.
Evaluating the adequacy of the Company’s disclosure in Notes 1 and 18 in relation to the income taxes.

Advanced Emissions Solutions, Inc. and Subsidiaries
Notes to Consolidated Financial Statements

Note 1 - Summary of Operations and Significant Accounting Policies

Nature of Operations  

Advanced Emissions Solutions, Inc. ("ADES" or the "Company") is a Delaware corporation with its principal office located in 
Greenwood Village, Colorado and operations located in Louisiana. The Company is principally engaged in the sale of 
consumable air and water treatment options including activated carbon ("AC") and chemical technologies. The Company's 
proprietary technologies in the advanced purification technologies ("APT") market enable customers to reduce air and water 
contaminants, including mercury and other pollutants, to maximize utilization levels and to improve operating efficiencies to 
meet the challenges of existing and pending emission control regulations. Through its wholly-owned subsidiary, ADA Carbon 
Solutions, LLC ("Carbon Solutions"), the Company manufactures and sells AC used to capture and remove contaminants for 
coal-fired power plants, industrial and water treatment markets. Carbon Solutions also owns an associated lignite mine ("Five 
Forks Mine") that supplies the primary raw material for manufacturing AC. 

Through its equity ownership in Tinuum Group, LLC ("Tinuum Group") and Tinuum Services, LLC ("Tinuum Services"), both 
of which are unconsolidated entities, the Company generates substantial earnings. Tinuum Group provides reduction of 
mercury and nitrogen oxide ("NOx") emissions at select coal-fired power generators through the production and sale of refined 
coal ("RC") that qualifies for tax credits ("Section 45 tax credits") under the Internal Revenue Code ("IRC") Section 45 - 
Production Tax Credit (the "Section 45 tax credit program"). The Company also earns royalties for technologies that are 
licensed to Tinuum Group and used at certain RC facilities to enhance combustion and reduced emissions of NOx and mercury 
from coal burned to generate electrical power. Tinuum Services operates and maintains the RC facilities under operating and 
maintenance agreements with Tinuum Group and owners or lessees of the RC facilities. 

Effective December 31, 2021, the Section 45 tax credit program expired and, as a result, both Tinuum Group and Tinuum 
Services ceased operations and are winding down their respective businesses. Beginning in 2022, our equity earnings generated 
from both Tinuum Group and Tinuum Services are expected to be minimal. In addition, license royalties earned from Tinuum 
Group ceased as of December 31, 2021.

Principles of Consolidation 

The Consolidated Financial Statements include accounts of wholly-owned subsidiaries and variable interest entities ("VIEs") in 
which the Company is the primary beneficiary. All significant intercompany balances and transactions have been eliminated in 
consolidation. 

All investments in partially owned entities for which the Company has greater than 20% ownership are accounted for using the 
equity method based on the legal form of the Company's ownership percentage and are included in the Equity method 
investments line item in the Consolidated Balance Sheets. As of December 31, 2021, the Company holds equity interests of 
42.5% and 50.0% in Tinuum Group and Tinuum Services, LLC ("Tinuum Services"), respectively.

Cash, cash equivalents and restricted cash

Cash and cash equivalents include bank deposits and other highly liquid investments purchased with an original maturity of 
three months or less. 

Restricted cash primarily consists of a surety bond indemnification agreement (the "Surety Agreement") associated with 
reclamation of a mine. As of December 31, 2020, restricted cash also consisted of minimum cash balance requirements under a 
line of credit agreement (the "Line of Credit") with a bank (the "Lender"). Restricted cash is classified consistent with the 
underlying obligation.

Receivables, net

Receivables, net are recorded at net realizable value, which includes an appropriate allowance for estimated uncollectible 
amounts to reflect any loss anticipated on the receivables balances. Increases and decreases in the allowance for doubtful 
accounts are established based upon changes in the credit quality of receivables and are included as a component of the General 
and administrative line item in the Consolidated Statements of Operations. The allowance for doubtful accounts is based on 
historical experience, general economic conditions and the credit quality of specific accounts.

57

Advanced Emissions Solutions, Inc. and Subsidiaries
Notes to Consolidated Financial Statements

Inventories, net

Inventories, net are stated at the lower of average cost or net realizable value and consist principally of raw materials and 
finished goods related to the Company's AC and chemical product offerings. The cost of inventory is determined using the 
average cost method.

Inventories are periodically reviewed for both potential obsolescence and potential declines in anticipated selling prices. In this 
review, the Company makes assumptions about the future demand for and market value of the inventory and estimates the 
amount of any obsolete, unmarketable, slow moving or overvalued inventory. If applicable, the Company will write down the 
value of inventories by an amount equal to the difference between the cost of the inventory and its estimated net realizable 
value. 

Additional details regarding Inventory balances are included in Note 9. 

Intangible Assets 

Intangible assets consist of patents, licensed technology, customer relationships, developed technologies and trade names. 

The Company has developed technologies resulting in patents being granted by the U.S. Patent and Trademark Office or other 
regulatory offices. Legal costs associated with securing the patent are capitalized and amortized over the legal or useful life 
beginning on the patent filing date.

the year ended December 31, 2020 and further described in Note 6.

Included in the Consolidated Statements of Operations is amortization expense related to intangible assets of $0.9 million and 
$1.0 million for the years ended December 31, 2021 and 2020, respectively. The estimated future amortization expense for 
existing intangible assets as of December 31, 2021 is expected to be $0.2 million for each of the five succeeding fiscal years.  

Investments

The investments in entities in which the Company does not have a controlling interest (financial or operating), but where it has 
the ability to exercise significant influence over operating and financial policies, are accounted for using the equity method of 
accounting. Whether or not the Company exercises significant influence with respect to an investee depends on an evaluation of 
several factors including, among others, representation on the investee company’s board of directors and the Company's 
ownership level. Under the equity method of accounting, an investee company’s financial statements are not consolidated in the 
Company’s Consolidated Balance Sheets and Consolidated Statements of Operations; however, the Company’s share of the 
earnings or losses of the investee company is reported in the "Earnings from equity method investments" line item in the 
Consolidated Statements of Operations, and the Company’s carrying value in an equity method investee company is reported in 
the "Equity method investments"line in the Consolidated Balance Sheets. 

When the Company receives distributions in excess of the carrying value of the investment and has not guaranteed any 
obligations of the investee and/or is not required to provide additional funding to the investee, the Company recognizes such 
excess distributions as equity method earnings in the period the distributions occur. When the investee subsequently reports 
income, the Company does not record its share of such income until it equals the amount of distributions in excess of carrying 
value that were previously recognized in income. During the years ended December 31, 2021 and 2020, the Company had no 
guarantees or requirements to provide additional funding to investees.

58

 
 
 
 
 
 
 
 
Advanced Emissions Solutions, Inc. and Subsidiaries
Notes to Consolidated Financial Statements

Additionally, when the Company's carrying value in an equity method investment is zero, and the Company has not guaranteed 
any obligations of the investee and/or is not required to provide additional funding to the investee, the Company will not 
recognize its share of any reported losses by the investee until future earnings are generated to offset previously unrecognized 
losses. As a result, equity income or loss reported in the Company's Consolidated Statements of Operations for certain equity 
method investees may differ from a mathematical calculation of net income or loss attributable to its equity interest based on 
the percentage ownership of the Company's equity interest and the net income or loss attributable to equity owners as shown in 
the investee company's statements of operations. Likewise, distributions from equity method investees are reported in the 
Consolidated Statements of Cash Flows as "return on investment" in Operating cash flows until such time as the carrying value 
in an equity method investee company is reduced to zero; thereafter, such distributions are reported as "distributions in excess 
of cumulative earnings" in Investing cash flows. See Note 8 for additional information regarding the Company's equity method 
investments.  

Investments in partially-owned subsidiaries for which the Company has less-than-20% ownership are accounted for in 
accordance with accounting guidance applicable to equity investments that do not qualify for the equity method of accounting. 
The Company evaluates these types of investments for changes in fair value and, if there is change, recognizes the change in the 
Consolidated Statement of Operations. If no such events or changes in circumstances have occurred related to these types of 
investments, the fair value is estimated only if practicable to do so.

Property, Plant and Equipment 

Property, plant and equipment are stated at cost less accumulated depreciation and includes leasehold improvements. 
Depreciation on assets is computed using the straight-line method over the lesser of the estimated useful lives of the related 
assets or the lease term (ranging from 2 to 31 years). Maintenance and repairs that do not extend the useful life of the respective 
asset are charged to Operating expenses as incurred. When assets are retired, or otherwise disposed of, the property accounts are 
relieved of costs and accumulated depreciation and any resulting gain or loss is credited or charged to income. The Company 
performs an evaluation of the recoverability of the carrying value of  property, plant and equipment to determine if facts and 
circumstances indicate that their carrying values may be impaired. Impairment charges are recorded to "Operating expenses" in 
the Consolidated Statements of Operations. Amortization of finance leased assets is included in depreciation expense and is 
calculated using the straight-line method over the term of the lease.

Leases

The Company records a right of use ("ROU") asset and related liability under a contract or part of a contract when it conveys 
the right to control the use of an identified asset for a period of time in exchange for consideration. Control over the use of an 
identified asset occurs when an entity has both the right to obtain substantially all of the economic benefits from the use of an 
identified asset and the right to direct the use of that identified asset. The determination of whether a contract contains a lease 
may require significant assumptions and judgments.

For all classes of underlying assets, the Company does not separate nonlease components from lease components and accounts 
for each separate lease component and the nonlease components associated with that lease component as a single lease 
component. The Company records lease liabilities and related ROU assets for all leases that have a term of greater than one 
year. For short-term leases (leases with terms of less than one year), the Company expenses lease payments on a straight-line 
basis over the lease term.

Variable lease payments represent payments made by a lessee for the right to use an underlying asset that vary because of 
changes in facts or circumstances occurring after the commencement date of a lease other than the passage of time. Variable 
lease payments that are based on an index or rate, calculated by using the index or rate that exists on the lease commencement 
date, are included in the measurement of a lease liability. Certain of the Company’s operating leases for office facilities contain 
variable lease components that are not based on an index or rate, and the Company recognizes these payments as lease expense 
in the period in which the obligation for those payments is incurred. 

The Company calculates lease liabilities based on the present value of lease payments discounted by the rate implicit in the 
lease or, if not readily determinable, the Company’s incremental borrowing rate.

Finance lease liabilities are subsequently measured by increasing the carrying amount to reflect interest expense on the finance 
lease liability and reducing the carrying amount of the lease liability to reflect lease payments made during the period. Interest 
on finance lease liabilities is determined in each period during the lease term as the amount that produces a constant periodic 
discount rate on the remaining balance of the lease liability. ROU assets under finance leases are amortized over the remaining 

59

Advanced Emissions Solutions, Inc. and Subsidiaries
Notes to Consolidated Financial Statements

lease term on a straight-line basis. Interest expense related to finance lease liabilities and amortization of ROU assets under 
finance leases are included in the "Interest expense" and "Depreciation, amortization, depletion and accretion" line item, 
respectively, in the Consolidated Statements of Operations.

Operating lease liabilities are subsequently measured at the present value of the lease payments not yet paid, discounted using 
the discount rate for the lease established at the inception date of the lease. ROU assets under operating leases are subsequently 
measured at the amounts of the related operating lease liability, adjusted for, as applicable, prepaid or accrued lease payments, 
the remaining balance of any lease incentives received, unamortized initial direct costs and impairment. Lease expense from 
operating leases is recognized as a single lease cost over the remaining lease term on a straight-line basis. Variable lease 
payments not included in operating lease liabilities are recognized as expense in the period in which the obligation for those 
payments is incurred. Lease expense from operating leases is included in the "General and administrative" and "Consumables 
Cost of revenues, excluding depreciation and amortization" line items in the Consolidated Statements of Operations.

Other Assets

Mine Development Costs

Mine development costs are related to the Five Forks Mine and are stated at cost less accumulated depletion and include 
acquisition costs, the cost of other development work and mitigation costs. Costs are amortized over the estimated life of the 
related mine reserves, which as of December 31, 2021 is estimated to be 13 years. The Company performs an evaluation of the 
recoverability of the carrying value of mine development costs to determine if facts and circumstances indicate that their 
carrying value may be impaired and if any adjustment is warranted. Mine development costs are reported in the "Other long-
term assets, net" line item in the Consolidated Balance Sheets.

Spare Parts

Spare parts include critical spares required to support plant operations. Parts and supply costs are determined using the lower of 
cost or estimated replacement cost. Parts are recorded as maintenance expenses in the period in which they are consumed. Spare 
parts are reported in the "Other long-term assets, net" line item in the Consolidated Balance Sheets.

Revenue Recognition

The Company recognizes revenue from a contract with a customer when a performance obligation under the terms of a contract 
with a customer is satisfied, which is when the customer controls the promised goods or services that are transferred in 
satisfaction of the performance obligation. Revenue is measured as the amount of consideration that is expected to be received 
in exchange for transferring goods or providing services, and the transaction price is generally fixed and generally does not 
contain variable or noncash consideration. In addition, the Company’s contracts with customers generally do not contain 
customer refund or return provisions or other similar obligations. Transfer of control and satisfaction of performance 
obligations are further discussed in each of the revenue components listed below.

The Company uses estimates and judgments in determining the nature and timing of satisfaction of performance obligations, the 
standalone selling price ("SSP") of performance obligations and the allocation of the transaction price to multiple performance 
obligations, if any.

The Company’s revenue components are Consumables sales and License royalties.

Consumables

The Company is principally engaged in the sale of consumable products that utilize AC and chemical based technologies to a 
broad range of customers, including coal-fired utilities, water treatment plants, and other diverse markets. Our proprietary 
technologies and associated product offerings provide purification solutions to enable our customers to reduce certain 
contaminants and pollutants and thus maximize utilization levels and improve operating efficiencies to meet the challenges of 
existing and potential regulations. 

The sale of consumable products is comprised of a single performance obligation and is recognized at the point in time when 
control transfers and our obligation has been fulfilled, which is when the product is shipped or delivered to a customer. 
Performance obligations for the sale of consumable products do not extend beyond one year.

The Company performs shipping and handling activities through the use of third-party shippers and such activities occur prior 
to a customer obtaining control of goods. As such, the Company accounts for these these activities as fulfillment activities and 
not as separate performance obligations. Shipping and handling costs incurred by the Company in delivering products to 

60

Notes to Consolidated Financial Statements

customers are billed to customers and are included in the transaction price and included in the "Revenues - Consumables" line 
item in the Consolidated Statements of Operations. Costs for shipping and handling activities incurred by the Company are 
included in the "Consumables Cost of revenues, excluding depreciation and amortization" line item in the Consolidated 
Statements of Operations. 

License royalties, related party

The Company generates revenues from royalties ("M-45 Royalties") earned under a licensing arrangement ("M-45 License") of 
its M-45TM and M-45-PCTM emissions control technologies ("M-45 Technology") between the Company and Tinuum Group. 
The Company recognizes M-45 Royalties at a point in time based on the use of the M-45 Technology at certain RC facilities or 
through Tinuum Group’s use of licensed technology for rates in excess of amounts allowed for RC application. The amount of 
M-45 Royalties recognized is generally based on a percentage of pre-tax margins (as defined in the M-45 License) of the RC 
facilities using the M-45 Technology.

Practical Expedients and Exemptions

The Company does not disclose the value of unsatisfied performance obligations for contracts with an original expected length 
of one year or less.

Sales and other taxes that are collected concurrently with revenue-producing activities are excluded from revenue.

The Company generally expenses sales commissions when incurred because the amortization period of the asset that the 
Company would have recognized is one year or less. These costs are recorded in sales and marketing expenses in the "General 
and administrative" line item in the Consolidated Statements of Operations.

Cost of Revenues 

Cost of revenues includes all labor, fringe benefits, subcontract labor, additive and coal costs, materials, equipment, supplies, 
travel costs and any other costs and expenses directly related to the Company’s production of revenues. 

Payroll and Benefits

Payroll and benefits costs include direct payroll, personnel related fringe benefits, sales and administrative staff labor costs and 
stock compensation expense. Payroll and benefits costs exclude direct labor included in Cost of revenues. 

Legal and Professional

Legal and professional costs include external legal, audit and consulting expenses.

General and Administrative

General and administrative costs include director fees and expenses, rent, insurance and occupancy-related expenses, bad debt 
expense, impairments and other general costs of conducting business.

Research and development costs are charged to expense in the period incurred and are reported in the "General and 
administrative" line item in the Consolidated Statements of Operations. For the years ended December 31, 2021 and 2020, the 
Company recorded research and development costs of $0.4 million and $1.0 million, respectively.

Asset Retirement Obligations

Asset retirement obligations ("ARO") are comprised of mine reclamation activities required under operating agreements related 
to the Five Forks Mine and the Marshall Mine (as defined in Note 4) and are recognized when incurred and recorded as 
liabilities at fair value. An ARO is accreted over time through periodic charges to earnings. Accounting for reclamation and 
remediation obligations requires the Company to make estimates of future costs unique to a specific mining operation that the 
Company expects to incur to complete the reclamation and remediation work required to comply with existing laws and 
regulations. AROs are periodically adjusted to reflect changes in the estimated present value resulting from the passage of time 
and revisions to the estimates of either the timing or amount of the reclamation costs.

61

Advanced Emissions Solutions, Inc. and Subsidiaries
Notes to Consolidated Financial Statements

Five Forks Mine 

For the Five Forks Mine ARO, a corresponding ARO asset is depreciated over its estimated life. Reclamation costs related to 
the Five Forks Mine are allocated to expense over the life of the related mine assets, and are periodically adjusted to reflect 
changes in the estimated present value resulting from the passage of time and revisions to the estimates of either the timing or 
amount of the reclamation costs. Remediation costs for the Five Forks Mine are accrued based on management’s best estimate 
at the end of each period of the costs expected to be incurred. Such cost estimates may include ongoing care, maintenance and 
monitoring costs. Reclamation obligations are based on the timing of estimated spending for an existing environmental 
disturbance. On an annual basis, unless otherwise deemed necessary, the Company reviews its estimates and assumptions of the 
Five Forks Mine ARO.

The Company’s mining activities at the Five Forks Mine are subject to various domestic laws and regulations governing the 
protection of the environment. The Company conducts its mining activities to protect public health and the environment and 
believes its operations are in compliance with applicable laws and regulations in all material respects. The Company has made, 
and expects to make in the future, expenditures to comply with such laws and regulations, but cannot predict the full amount of 
such future expenditures. Estimated future reclamation costs are based principally on current legal and regulatory requirements.

Marshall Mine (refer to Note 4)

Reclamation costs related to the Marshall Mine are largely based on a capped fee structure based on the initial estimate of the 
total costs of reclamation, which provides for certain contingencies that could increase or decrease the reclamation fee based on 
the reclamation agreement executed between the Company and the Marshall Mine operator. The timing of payments and actual 
reclamation costs may change and the Company accounts for these changes on a quarterly basis. 

Income Taxes

The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax 
assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. 
Under this method, deferred income taxes are provided for temporary differences between the financial reporting basis and tax 
basis of the Company's assets and liabilities and are tax-effected using enacted tax rates in effect for the year in which the 
temporary differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is 
recognized in operations in the period that includes the enactment date. 

The Company maintains valuation allowances where it is more likely than not that all or a portion of deferred tax assets will not 
be realized. In making such a determination, the Company considers all available positive and negative evidence, including 
future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results 
of recent operations. 

The Company records uncertain tax positions on the basis of a two-step process whereby (1) the Company determines whether 
it is more-likely-than-not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for 
those tax positions that meet the more-likely-than-not recognition threshold, the Company recognizes the amount of tax benefit 
that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority.

Based on its ownership in Tinuum Group, the Company records its pro-rata share for interest expense resulting from the sale of, 
or lease income generated from, RC facilities that are treated as installment sales for federal income purposes, pursuant to IRS 
section 453A ("Section 453A"). Section 453A requires taxpayers using the installment method to pay an interest charge ("453A 
interest") on the portion of the tax liability that is deferred under the installment method. The Company recognizes 453A 
interest and other interest and penalties related to unrecognized tax benefits in the "Interest expense" line item in the 
Consolidated Statements of Operations. 

Stock-Based Compensation

Stock-based compensation expense is measured at the grant date based on the estimated fair value of the stock-based award and 
is generally expensed on a straight-line basis over the requisite service period and/or performance period of the award. 
Forfeitures are recognized when incurred. Stock-based compensation expense related to manufacturing employees and 
administrative employees is included in the "Consumables Cost of revenues, exclusive of depreciation and amortization"  
and "Payroll and benefits" line items, respectively, in the Consolidated Statements of Operations. Stock-based compensation 
expense related to non-employee directors and consultants is included in the "General and administrative" line item in 
the Consolidated Statements of Operations.

Dividends

When a sufficient amount of available earnings exists at the time of a dividend declaration, dividends are charged to Retained 
earnings when declared. If a sufficient amount of available earnings is not available, dividends declared are charged as a 
reduction to Additional paid-in capital.

Earnings (Loss) Per Share

Basic earnings (loss) per share is computed using the weighted-average number of shares of common stock outstanding during 
the reporting period. Diluted earnings per share is computed in a manner consistent with that of basic earnings per share, while 
considering other potentially dilutive securities. The treasury stock method is used to determine the dilutive effect of potentially 
dilutive securities. 

Potentially dilutive securities consist of restricted stock awards ("RSA's"), as well as outstanding options to purchase common 
stock ("Stock Options") and contingent performance stock units ("PSU's") (collectively, "Potential dilutive shares"). The 
dilutive effect, if any, for non-participating RSA's, Stock Options and PSU's is determined using the greater of dilution as 
calculated under the treasury stock method or the two-class method. Potential dilutive shares are excluded from diluted earnings 
(loss) per share when their effect is anti-dilutive. When there is a net loss for a period, all Potential dilutive shares are anti-
dilutive and are excluded from the calculation of diluted loss per share for that period.

Each PSU represents a contingent right to receive shares of the Company’s common stock, and the number of shares may range 
from zero to two times the number of PSU's granted on the award date depending upon the price performance of the Company's 
common stock as measured against a general index and a specific peer group index over requisite performance periods. The 
number of Potential dilutive shares related to PSU's is based on the number of shares of the Company's common stock, if any, 
that would be issuable at the end of the respective reporting period, assuming that the end of the reporting period is the end of 
the contingency period applicable to such PSU's. See Note 16 for additional information related to PSU's.

The following table sets forth the calculations of basic and diluted earnings per common share:

Use of Estimates

The preparation of the Company’s consolidated financial statements in conformity with accounting principles generally 
accepted in the United States ("GAAP") requires the Company’s management to make estimates and assumptions that affect the 
amounts reported in these financial statements and accompanying notes. Actual results could differ from those estimates. 
Significant financial statement components in which the Company makes assumptions include 

•

•

•

business combinations, including asset acquisitions;

the carrying value of its long-lived assets;

AROs; and 

•

income taxes, including the valuation allowance for deferred tax assets and assessment of uncertain tax positions.
Due to the coronavirus ("COVID-19") pandemic, there has been uncertainty and disruption in the global economy and financial 
markets. Additionally, due to COVID-19, overall power generation and coal-fired power demand may change, which could also 

63

 
 
 
 
 
 
 
Advanced Emissions Solutions, Inc. and Subsidiaries
Notes to Consolidated Financial Statements

have a material adverse effect on the Company. The Company is not aware of any specific event or circumstance due to 
COVID-19 that would require an update to its estimates or judgments or a revision of the carrying values of its assets or 
liabilities through the date of this Report. These estimates may change as new events occur and additional information is 
obtained. Actual results could differ materially from these estimates under different assumptions or conditions

Risks and Uncertainties

As of December 31, 2021, all RC facilities had ceased operations and Tinuum is expected to complete reclamation activities, as 
required, during 2022. The loss of earnings from both Tinuum Group and Tinuum Services will have a significant adverse 
impact on our financial position, results of operations and cash flows beginning in 2022 and beyond.

Reclassifications

Certain balances have been reclassified from prior years to conform to the current year presentation. Such reclassifications had 
no effect on the Company’s results of operations or financial position in any of the periods presented.

New Accounting Guidance

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326) Measurement of Credit Losses 
on Financial Instruments ("ASU 2016-13"). The main objective of ASU 2016-13 is to provide financial statement users with 
more decision-useful information about the expected credit losses on financial instruments and other commitments to extend 
credit held by a reporting entity at each reporting date. To achieve this objective, the amendments in ASU 2016-13 replace the 
incurred loss impairment methodology in current  GAAP with a methodology that reflects expected credit losses and requires 
consideration of a broader range of reasonable and supportable information to inform credit loss estimates. ASU 2016-13 is 
effective for "smaller reporting companies" (as defined by the Securities and Exchange Commission) for fiscal years beginning 
after December 15, 2022, including interim periods within those years, and must be adopted under a modified retrospective 
method approach. Entities may adopt ASU 2016-13 earlier as of the fiscal years beginning after December 15, 2018, including 
interim periods within those years. The Company intends to adopt ASU 2016-13 effective January 1, 2023 and is currently 
evaluating the provisions of this standard and assessing its impact on the Company's financial statements and disclosures. The 
Company does not believe this standard will have a material impact on the Company's financial statements and disclosures.

Note 2 - Restatement

Subsequent to the filing of its Quarterly Report for the quarterly period ended September 30, 2021, the Company reassessed its 
presentation of shipping and handling costs billed to its customers in its Consolidated Statement of Operations for the year 
ended December 31, 2021. Historically, the Company has accounted for shipping and handling costs billed to customers as a 
reduction of consumables cost of revenues, as presented in the Consumables cost of revenues, exclusive of depreciation and 
amortization line item in the Consolidated Statements of Operations. Under Accounting Standards Codification 606 - Revenue 
from Contracts with Customers, shipping and handling costs billed to customers are considered a component of the total 
transaction price in a contract with a customer and should be presented as revenues.

The Company concluded that its historical presentation of shipping and handling costs billed to customers as a component of 
cost of revenues rather than as a component of revenues was incorrect and that the Company's presentation of both the 
"Revenues - Consumables" and "Consumables cost of revenues, exclusive of depreciation and amortization" line items for the 
year ended December 31, 2020 should be restated. The impact of this error resulted in an understatement of both the "Revenues 
- Consumables" and "Consumables cost of revenues, exclusive of depreciation and amortization" line items in the Consolidated 
Statements of Operations for the year ended December 31, 2020, but had no impact to operating income (loss), income (loss) 
before income taxes, net income (loss) or earnings (loss) per share for these years. Further, there was no impact of this error to 
the Consolidated Balance Sheets, Consolidated Statements of Stockholders' Equity or Consolidated Statements of Cash Flow as 
of and for the year ended December 31, 2020.

On September 30, 2020, the Company and Cabot Norit Americas, Inc., ("Cabot") entered into a supply agreement (the "Supply 
Agreement") pursuant to which the Company agreed to sell and deliver to Cabot, and Cabot agreed to purchase and accept from 
the Company certain lignite-based AC products ("Furnace Products"). The term of the Supply Agreement is for 15 years with 
10-year renewal terms that are automatic unless either party provides three years prior notice of intention not to renew before 
the end of any term. 

In addition to the sale by the Company and purchase by Cabot of Furnace Products, the Company and Cabot have agreed to 
additional terms whereby Cabot reimburses the Company for certain capital expenditures incurred by the Company that are 
necessary to manufacture the Furnace Products. Reimbursements are comprised of  revenues earned from capital expenditures 
incurred that will benefit both the Company and Cabot (referred to as "Shared Capital") and revenues earned from capital 
expenditures incurred that will benefit Cabot exclusively (referred to as "Specific Capital"). In the event that Cabot ceases to 
make purchases under the Supply Agreement, Cabot is obligated to pay the balance of any outstanding payments for Specific 
Capital.

Note 4 - Acquisition of Marshall Mine

Concurrently with the execution of the Supply Agreement, on September 30, 2020, the Company entered into an agreement to 
purchase (the "Mine Purchase Agreement") from Cabot 100% of the membership interests in Marshall Mine, LLC (the 
"Marshall Mine Acquisition") for a nominal purchase price. Marshall Mine, LLC owns a lignite mine located outside of 
Marshall, Texas (the "Marshall Mine"). The Company independently determined to immediately commence activities to shutter 
the Marshall Mine and to incur the associated reclamation costs. 

In conjunction with the execution of the Supply Agreement and the Mine Purchase Agreement, on September 30, 2020, the 
Company entered into a reclamation contract (the "Reclamation Contract") with a third party that provides a capped cost, 
subject to certain contingencies, in the initial amount of approximately $19.7 million plus an obligation to pay certain direct 
costs of approximately $3.6 million (collectively, the "Reclamation Costs") over the estimated reclamation period of 10 years 
(the "Reclamation Period"). Under the terms of the Supply Agreement, Cabot is obligated to reimburse the Company for $10.2 
million of the Reclamation Costs (the "Reclamation Reimbursement"), payments of which are due semi-annually over the 
estimated reclamation period and are inclusive of interest. In the event that Cabot has a change in control as described in the 
Supply Agreement, all outstanding balances of the Reclamation Reimbursement shall be due and payable in full. See further 
discussion of the Reclamation Costs and Reclamation Reimbursement in Note 5.

As the owner of the Marshall Mine, the Company is required to post a surety bond to ensure performance of its reclamation 
activities and entered into the Surety Agreement on September 30, 2020. As of December 31, 2021, the Company had a $16.6 
million surety bond (the "Surety Bond") posted with the local regulatory agency. The Surety Bond will remain in place until the 
Marshall Mine is fully shuttered, and it may be reduced in amount from time to time as the Company progresses with its 
reclamation activities. As of December 31, 2021 and 2020, for the obligations due under the Reclamation Contract, the 

65

 
 
 
 
 
 
 
Advanced Emissions Solutions, Inc. and Subsidiaries
Notes to Consolidated Financial Statements

Company posted cash collateral of $10.0 million and $5.0 million, respectively, which is reported as "Restricted Cash, long-
term" in the Consolidated Balance Sheets.

The Marshall Mine Acquisition included the acquisition of certain assets that will be consumed and the assumption of certain 
liabilities that will be paid in reclamation of the Marshall Mine, in addition to the incurrence of an obligation for the 
Reclamation Costs. The Company determined that the Marshall Mine Acquisition should be accounted for as an asset 
acquisition as it did not meet the definition of a business. The Company's conclusion was based on the Marshall Mine not 
having any economic reserves, as the Company commenced full reclamation as of September 30, 2020, and therefore lacked 
inputs.

As the Marshall Mine Acquisition represented a transaction with a customer of net assets acquired and liabilities assumed from 
Cabot, the Company accounted for the excess of the fair value of liabilities assumed over assets acquired as upfront 
consideration transferred to a customer, Cabot (the "Upfront Customer Consideration"). The amount of the Upfront Customer 
Consideration was recognized net of an additional asset recognized in the Marshall Mine Acquisition, which was comprised of 
a receivable from Cabot (the "Cabot Receivable") for the Reclamation Reimbursements. The Cabot Receivable is further 
discussed in Note 5.

The total Upfront Customer Consideration is amortized on a straight-line basis as a reduction to revenue over the expected 15-
year contractual period of the Supply Agreement.

The Company paid a nominal cash amount to Cabot in the form of cash for the Marshall Mine and also assumed liabilities 
whose fair value exceeded the fair value of assets acquired. The net assets acquired and liabilities assumed and the additional 
assets recorded for the Marshal Mine Acquisition as of September 30, 2020 are shown in the table below. Subsequent to this 
date, the Company completed additional analysis and adjustments were made as noted in the table below:

The Company also evaluated the Marshall Mine entity as a VIE, and determined that because of its structure and closing-stage 
status, it does not have sufficient equity at-risk and would not likely be able to obtain additional subordinated financial support 
to complete its closing stage obligations. The Company purchased all of the membership interests in Marshall Mine, LLC and 
determined that it met the definition of a VIE and that the Company is the primary beneficiary. Therefore, Marshall Mine, 
LLC’s assets and liabilities are consolidated.

Note 5 - Marshall Mine Asset Retirement Obligation and related Cabot Receivable

Asset Retirement Obligation

In connection with the Supply Agreement, Mine Purchase Agreement and the Reclamation Contract, the Company assumed the 
obligation to reclaim and restore the land associated with the Marshall Mine. The Company determined that the Marshall Mine 
did not have any remaining economic reserves. As of September 30, 2020, the Company recorded an ARO (the "Marshall Mine 
ARO") as its best estimate for the total Reclamation Costs of $21.3 million as measured at the estimated future cash flows of 
$23.7 million, inclusive of contingency costs, discounted to their present value using a discount rate based on a credit-adjusted, 
risk-free rate of 7.0%. 

As of June 30, 2021 and December 31, 2021, the Company revised its estimate of future obligations owed for the reclamation 
of the Marshall Mine primarily based on scope reductions related to future reclamation requirements. As a result, the Company 
reduced the Marshall Mine ARO by $1.9 million as of June 30, 2021 and $0.8 million as of December 31, 2021 and recorded a 
corresponding gain on change in estimate of $2.7 million for the year ended December 31, 2021. This is included as "Gain on 
change in estimate, asset retirement obligation" in the Consolidated Statement of Operations for the year ended December 31, 
2021.

Cabot Receivable

As previously disclosed, under the terms of the related Supply Agreement, Cabot is obligated to pay the Reclamation 
Reimbursement to the Company for $10.2 million of the Reclamation Costs, inclusive of interest. As of September 30, 2020, 
the Company recorded the Cabot Receivable for the Reclamation Reimbursement at its estimated fair value, which was 
measured using a discounted cash flows valuation model that considered the estimated credit risk associated with the obligor’s 
(Cabot’s) future performance. Interest is accreted on a monthly basis and recognized as interest income. There were no 
significant related fees or costs associated with the Cabot Receivable.

As of September 30, 2020, the Company recorded the Cabot Receivable at its estimated fair value of $9.7 million, reflecting a 
discount rate of approximately 1.5% or $0.5 million. Allowances for this asset are assessed periodically, and no allowance was 
deemed necessary as of December 31, 2021 or 2020.

Note 6 - Impairment

As part of its periodic review of the carrying value of long-lived assets, the Company assessed its long-lived assets for potential 
impairment. In assessing impairment of its APT segment's long-lived asset groups as of June 30, 2021, the Company considered 
factors such as the significant decline in both the APT segment's trailing twelve months revenues and current and future years’ 
forecasted revenues. These factors were largely due to the significant drop in coal-fired power dispatch amid historically low 
prices of alternative power generation sources, such as natural gas, leading to an increase in natural gas usage as well as other 
competing energy sources. 

As of June 30, 2020, the Company completed an undiscounted cash flow analysis of its APT segment's long-lived assets (the 
"Asset Group"), which were comprised of its manufacturing plant and related assets and its lignite mine assets. The estimated 
undiscounted cash flows from the Asset Group was $54.7 million, which was less than the carrying value of the Asset Group of 
$58.3 million. Accordingly, the Company completed an assessment of the Asset Group’s fair value and estimated the fair value 
of the Asset Group at $32.2 million. This resulted in an impairment and write-down of the Asset Group (the "Impairment 
Charge") of $26.1 million as of June 30, 2020. The Impairment Charge is reflected as "Impairment of long-lived assets" in the 
Consolidated Statement of Operations for the year ended December 31, 2020, and was allocated to the APT segment.

The following table summarizes the allocation to the Asset Group of the Impairment Charge of $26.1 million recorded as of 
June 30, 2020:

The Company engaged an independent third party to perform the valuation of the Asset Group in order to determine the 
estimated fair value of the Asset Group. This valuation was based on the use of several established valuation models including 
an expected future discounted cash flow model using Level 3 inputs. 

Note 7 - COVID-19

In March 2020, the federal government passed the Coronavirus Aid, Relief, and Security Act (the "CARES Act"), which
provided among other things the creation of the Paycheck Protection Plan ("PPP"), which was sponsored and administered by 
the U.S. Small Business Administration ("SBA"). On April 20, 2020, the Company executed a loan agreement (the "PPP 
Loan") under the PPP, evidenced by a promissory note, with BOK, NA dba Bank of Oklahoma ("BOK"), providing for 
$3.3 million in proceeds, which was funded to the Company on April 21, 2020. The PPP Loan was scheduled to mature on 
April 21, 2022, unless forgiven subject to terms and conditions established by the SBA. The Company initially recorded the 
PPP Loan as a debt obligation and accrued interest over its term.

On July 27, 2021, the Company received formal notification in the form of a letter dated July 19, 2021 from BOK that the SBA
approved the Company’s PPP Loan forgiveness application for the PPP Loan in the amount of $3.3 million (including accrued
interest). For the year ended December 31, 2021, the Company recorded a gain on extinguishment of the PPP Loan in the 
amount of $3.3 million in the Consolidated Statement of Operations, which is included as a component of "Other income 
(expense)."

The CARES Act also provided the deferral of payroll tax payments for all payroll taxes incurred through December 31, 2020. 
The Company elected to defer payments of payroll taxes for the periods allowed under the CARES Act in the amount of $0.4 
million and paid $0.2 million during the fourth quarter of 2021, with the balance due no later than December 31, 2022. 

Note 8 - Equity Method Investments

Tinuum Group, LLC 

As of December 31, 2021 and 2020, the Company’s ownership in Tinuum Group was 42.5%. Tinuum Group supplies 
technology, equipment and technical services to cyclone-fired and other boiler users, but its primary purpose is to place into 
operation facilities that produce and sell RC that lower emissions and therefore qualifies for Section 45 tax credits. NexGen

Notes to Consolidated Financial Statements

Refined Coal, LLC ("NexGen") and GSFS Investments I Corp. ("GSFS"), an affiliate of The Goldman Sachs Group, Inc. 
("GS"), own the remaining 42.5% and 15.0%, respectively of Tinuum Group. GSFS' ownership interest is in the form of Class 
B units that do not have voting rights but provide certain preferences over ADA and NexGen as to liquidation and profit 
distribution.

The Company determined that Tinuum Group is a VIE, however, it concluded that it was not the primary beneficiary and 
therefore did not consolidate Tinuum Group, and accounted for it under the equity method of accounting. The Company's 
conclusion that it was not the primary beneficiary was based on the Company's and NexGen's shared power of Tinuum Group.

For the year ended December 31, 2021, the Company recognized earnings from Tinuum Group's net income available to 
members that was different from its pro-rata share of Tinuum Group's net income available to members, as cash distributions 
for the year ended December 31, 2021 exceeded the carrying value of the Tinuum Group equity investment. For the year ended 
December 31, 2020, the Company recognized its pro-rata share of Tinuum Group's net income available to its members.

The carrying value of the Company's investment in Tinuum Group is zero as long as the cumulative amount of distributions 
received from Tinuum Group exceeds the Company's cumulative pro-rata share of Tinuum Group's net income available to 
Class A members. For periods during which the ending balance of the Company's investment in Tinuum Group is zero, the 
Company only recognizes equity earnings from Tinuum Group to the extent that cash distributions are received from Tinuum 
Group during the period. For periods during which the ending balance of the Company's investment is greater than zero (e.g., 
when the cumulative earnings in Tinuum Group exceeds cumulative cash distributions received), the Company recognizes its 
pro-rata share of Tinuum Group's net income available to Class A members for the period, less any amount necessary to recover 
the cumulative earnings short-fall balance as of the end of the immediately preceding period. As shown in the table below, the 
Company’s carrying value in Tinuum Group for the years ended December 31, 2021 and 2020 was zero and $3.4 million, 
respectively.

Tinuum Services, LLC

In 2010, the Company, together with NexGen, formed Tinuum Services for the purpose of operating and maintaining RC 
facilities, including those RC facilities leased or sold to third parties. The Company determined that Tinuum Services is not a 
VIE and evaluated Tinuum Services for potential consolidation under the voting interest model. Because the Company does not 
own greater than 50% of the outstanding voting shares, it has accounted for its investment in Tinuum Services under the equity 
method of accounting. As of December 31, 2021 and 2020, the Company’s investment in Tinuum Services was $2.4 million 
and $4.2 million, respectively.

Included in the Consolidated Statement of Operations of Tinuum Services for the years ended December 31, 2021 and 2020 
were losses related to VIE entities that are consolidated within Tinuum Services. These losses do not impact the Company's 
equity earnings from Tinuum Services as 100% of those losses are attributable to a noncontrolling interest and eliminated in the 
calculations of Tinuum Services' net income attributable to the Company's interest.

The Company evaluates its equity method investments for impairment whenever events or changes in circumstances indicate 
that the carrying amount of the investment might not be recoverable. As of December 31, 2021, the Company concluded the 
carrying amount of its investment in Tinuum Services was not fully recoverable due to the remaining expected future cash 
distributions to be received as Tinuum Services shutters its operations in 2022 as a result of the expiration of the Section 45 tax 
credit period as of December 31, 2021. As a result, the Company wrote-down its investment in the amount of $0.7 million, 
which is included in the "Earnings from equity method investments" line item in the Consolidated Statement of Operations for 
the year ended December 31, 2021.

Trade receivables represent an unconditional right to consideration in exchange for goods or services transferred to a customer. 
The Company invoices its customers in accordance with the terms of the contract. Credit terms are generally net 30 from the 
date of invoice. The timing between the satisfaction of performance obligations and when payment is due from the customer is 
generally not significant. The Company records allowances for doubtful trade receivables when it is probable that the balances 
will not be collected.

Note 14 - Commitments and Contingencies

Legal Proceedings

The Company is from time to time subject to, and is presently involved in, various pending or threatened legal actions and 
proceedings, including those that arise in the ordinary course of its business. Such matters are subject to many uncertainties and 
outcomes, the financial impacts of which are not predictable with assurance and that may not be known for extended periods of 
time. The Company records a liability in its consolidated financial statements for costs related to claims, settlements, and 
judgments where management has assessed that a loss is probable, and an amount can be reasonably estimated. The Company 
did not have any significant legal proceedings.

Restricted Cash

As of December 31, 2021 and 2020, the Company had long-term restricted cash of $10.0 million and $5.0 million, respectively, 
as required under the Surety Agreement related to the Reclamation Contract. As of  December 31, 2020, the Company had 
short-term restricted cash of $5.0 million as required under a minimum cash balance requirement of a Senior Term Loan 
covenant.

Surety Bonds

As of December 31, 2021, the Company had outstanding surety bonds of $24.1 million related to performance requirements 
under reclamation contracts associated with both the Five Forks Mine and the Marshall Mine. 

Other Commitments and Contingencies

The Company also has certain limited obligations contingent upon future events in connection with the activities of Tinuum 
Group. The Company, NexGen and two entities affiliated with NexGen have provided GSFS with limited guaranties (the 
"Tinuum Group Party Guaranties") related to certain losses it may suffer as a result of inaccuracies or breach of representations 
and covenants. The Company also is a party to a contribution agreement with NexGen under which any party called upon to 
pay on a Tinuum Group Party Guaranty is entitled to receive contribution from the other party equal to 50% of the amount paid. 
No liability or expense provision has been recorded by the Company related to this contingent obligation as the Company 
believes that it is not probable that a loss will occur with respect to Tinuum Group Party Guaranties.

Note 15 - Stockholders' Equity

The Company has two classes of capital stock authorized, common stock and preferred stock, which are described as follows: 

Preferred Stock

The Company's Board of Directors (the "Board") is authorized to provide out of the unissued shares of Preferred Stock and to 
fix the number of shares constituting a series of Preferred Stock and, with respect to each series, to fix the number of shares and 
designation of such series, the voting powers, if any, the preferences and relative, participating, option or other special rights, if 
any, and any qualifications, limitations or restrictions thereof, of the shares of such series. As of December 31, 2021 and 2020, 
there were no shares of Preferred Stock designated or outstanding. 

Common Stock

Holders of common stock are entitled to one vote for each share held of record on all matters submitted to a vote of the 
stockholders. Additionally, holders of common stock are entitled to receive dividends when and if declared by the Board, 
subject to any statutory or contractual restrictions on payment of dividends and to any restrictions on the payment of dividends 
imposed by the terms of any outstanding shares of preferred stock. 

Upon dissolution, liquidation or the sale of all or substantially all of the Company's assets, after payment in full of any amounts 
required to be paid to creditors and to the holders of preferred stock having liquidation preferences, if any, the holders of shares 
of common stock will be entitled to receive the Company's remaining assets for distribution on a pro rata basis. 

Stock Repurchase Programs

In November 2018, the Board authorized the Company to purchase up to $20.0 million of its outstanding common stock under a 
stock repurchase program (the "Stock Repurchase Program"), which was to remain in effect until December 31, 2019 unless 
otherwise modified by the Board. In November 2019, the Board authorized an incremental $7.1 million to the Stock 
Repurchase Program and provided that it will remain in effect until all amounts are utilized or it is otherwise modified by the 
Board. 

For the years ended December 31, 2021 and 2020, under the Stock Repurchase Program, the Company purchased zero and 
20,613 shares of its common stock for cash of zero and $0.2 million, inclusive of commissions and fees, respectively. As of 
December 31, 2021, the Company had $7.0 million remaining under the Stock Repurchase Program.

Tax Asset Protection Plan

U.S. federal income tax rules, and Section 382 of the Internal Revenue Code in particular, could substantially limit the use of 
net operating losses and other tax assets if the Company experiences an "ownership change" (as defined in the Internal Revenue 
Code). In general, an ownership change occurs if there is a cumulative change in the ownership of the Company by "5 percent 
stockholders" that exceeds 50 percentage points over a rolling three-year period. 

On May 5, 2017, the Board approved the declaration of a dividend of rights to purchase Series B Junior Participating Preferred 
Stock for each outstanding share of common stock as part of a tax asset protection plan (the "TAPP") designed to protect the 
Company’s ability to utilize its net operating losses and tax credits. The TAPP is intended to act as a deterrent to any person 
acquiring beneficial ownership of 4.99% or more of the Company’s outstanding common stock.

On April 9, 2021, the Board approved the Fourth Amendment to the TAPP ("Fourth Amendment") that amends the TAPP, as 
previously amended by the First, Second and Third Amendments that were approved the Board on April 6, 2018, April 5, 2019 
and April 9, 2020, respectively. The Fourth Amendment amends the definition of "Final Expiration Date" under the TAPP to 
extend the duration of the TAPP and makes associated changes in connection therewith. At the Company's 2021 annual meeting 
of stockholders, the Company's stockholders approved the Fourth Amendment, thus the Final Expiration Date will be the close 
of business on December 31, 2022.

Note 16 - Stock-Based Compensation

On June 20, 2017, the Company's stockholders approved the 2017 Omnibus Incentive Plan (the "2017 Plan"), which permits 
grants of awards to employees, directors and non-employees. Awards may be in the form of shares, rights to purchase restricted 
stock, bonuses of restricted stock, or other rights or benefits as described under the 2017 Plan. As of December 31, 2021, the 
Company has 644,540 shares of its common stock authorized for issuance under the 2017 Plan. 

Expense

RSA's - Restricted Stock Awards ("RSA's") are typically granted with vesting terms of three years.  The fair value of RSA's is 
determined based on the closing price of the Company’s common stock on the authorization date of the grant multiplied by the 
number of shares subject to the stock award. Compensation expense for RSA's is generally recognized over the vesting term on 
a straight-line basis.  

PSU's - Performance share units ("PSU's") generally vest over three years and are based on the grantee’s continuous service 
with the Company, performance measures or a combination of both. Each PSU represents a contingent right to receive shares of 
the Company’s common stock if the Company meets certain performance measures over the requisite period. 

Compensation expense is recognized for PSU awards on a straight-line basis over the vesting period based on the estimated fair 
value at the date of grant using a Monte Carlo simulation model. 

Risk-free interest rate - The risk-free interest rate for PSU's granted during the period was determined by using a zero-coupon, 
U.S. Treasury rate for the periods that coincided with the expected terms listed above.

Dividends - As the PSU's granted receive dividend equivalent units, no discount was applied for any dividends declared.

Expected volatility - To calculate expected volatility, the historical volatility of the Company's common stock was used.

Performance period - The Company’s performance period is based upon the vesting term of the Company’s PSU awards.

Spare parts include critical spares required to support plant operations. Parts and supply costs are determined using the lower of 
cost or estimated replacement cost. Parts are recorded as maintenance expenses in the period in which they are consumed.

Mine development costs include acquisition costs, the cost of other development work and mitigation costs related to the Five 
Forks Mine and are depleted over the estimated life of the related mine reserves, which is estimated to be 13 years as of 
December 31, 2021. The Company performs an evaluation of the recoverability of the carrying value of mine development 
costs to determine if facts and circumstances indicate that their carrying value may be impaired and if any adjustment is 
warranted. Mine reclamation asset represents the ARO asset related to the Five Forks Mine and is depreciated over its estimated 
life.

The Company holds a long-term investment (the "Highview Investment") in Highview Enterprises Limited ("Highview"), a 
London, England based developmental stage company specializing in power storage. In November 2014, the Company 
acquired an 8% ownership interest in the common stock of Highview for $2.8 million in cash. The Company accounts for the

Highview Investment as an investment recorded at cost, less impairment, plus or minus observable changes in price for 
identical or similar investments of the same issuer.

The Highview Investment is evaluated for indicators of impairment such as an event or change in circumstances that may have 
a significant adverse effect on the fair value of the investment. There were no changes to the carrying value of the Highview 
Investment for the years ended December 31, 2021 and 2020 as there were no indicators of impairment or observable price 
changes for equity issued by Highview. Since inception of Highview Investment, the Company has recognized $2.2 million of

Notes to Consolidated Financial Statements

Accounting for income taxes requires that companies assess whether a valuation allowance should be recorded against a 
deferred tax asset based on an assessment of the amount of the deferred tax asset that is “more likely than not” to be 
realized. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount that is more likely 
than not to be realized. 

The Company assesses a valuation allowance recorded against deferred tax assets at each reporting date. The determination of 
whether a valuation allowance is appropriate requires the evaluation of positive and negative evidence that can be objectively 
verified. Consideration must be given to all sources of taxable income available to realize a deferred tax asset, including, as 
applicable, the future reversal of existing temporary differences, future taxable income forecasts exclusive of the reversal of 
temporary differences and carryforwards, taxable income in carryback years and tax planning strategies. In estimating taxes, the 
Company assesses the relative merits and risks of the appropriate tax treatment of transactions taking into account statutory, 
judicial and regulatory guidance.

As of December 31, 2021, the Company concluded it is more likely than not the Company will not generate sufficient taxable 
income within the applicable net operating loss and tax credit carry-forward periods to realize any of its net deferred tax assets. 
For the year ended December 31, 2021, the Company reduced a valuation allowance from December 31, 2020 by $1.3 million, 
but as of December 31, 2021 has a valuation allowance equal to 100% of its net deferred tax assets. In reaching this conclusion, 
the Company primarily considered forecasts of future taxable losses. 

The following table presents the approximate amount of state net operating loss carryforwards and federal tax credit 
carryforwards available to reduce future taxable income, along with the respective range of years that the net operating loss and 
tax credit carryforwards would expire if not utilized:

Note 20 - Fair Value Measurements

Fair Value of Financial Instruments

The carrying amounts of financial instruments, including cash and cash equivalents, accounts receivable, accounts payable, 
deposits and accrued expenses, approximate their fair values due to the short maturity of these instruments. The carrying 
amounts of the Senior Term Loan and other obligations, including finance leases, approximate their fair values based on credit 
terms and market interest rates currently available for similar instruments. Accordingly, these instruments are not presented in 
the table below. The following table provides the estimated fair values of the remaining financial instruments:

Concentration of credit risk

As of December 31, 2021, the Company’s financial instruments that are exposed to concentrations of credit risk consist 
primarily of cash and cash equivalents. The Company holds cash and cash equivalents at three financial institutions as of 
December 31, 2021. If those institutions were unable to perform their obligations, the Company would be at risk regarding the 
amount of its cash balance in excess of the federal deposit insurance corporation limits ($250 thousand). 

Assets and Liabilities Measured at Fair Value on a Recurring Basis

As of December 31, 2021 and December 31, 2020, the Company had no material financial instruments carried and measured at 
fair value on a recurring basis.

Assets and Liabilities Measured at Fair Value on a Non-Recurring Basis

As disclosed in Note 4, the Company completed the asset acquisition of Marshall Mine, LLC. The estimated fair values of the 
assets acquired and liabilities assumed were determined based on Level 3 inputs.

As disclosed in Note 6, the Company recorded an impairment charge related to the Asset Group based on a valuation model that 
included an expected future discounted cash flow model using Level 3 inputs.

As noted in Note 17, the Company accounts for the Highview Investment as an investment recorded at cost, less impairment, 
plus or minus observable changes in price for identical or similar investments of the same issuer. Fair value measurements, if 
any, represent either Level 2 or Level 3 measurements.

(1) During the fourth quarter of 2020, the Company recorded a gain  of 1.1 million related to the Settlement reached with the Former 
Customer as further described in Note 17.

(2) During the fourth quarter of 2020, the Company recorded income tax expense of $5.2 million primarily due to an increase in the valuation 
allowance as of December 31, 2020 related to the Company's deferred tax assets.

As discussed in Note 2, the Company concluded that its historical presentation of shipping and handling costs billed to 
customers as a component of cost of revenues rather than as a component of revenues was incorrect and that the Company's 
presentation of both the "Revenues - Consumables" and "Consumables cost of revenues, exclusive of depreciation and 
amortization" line items for the year ended December 31, 2020 should be restated. The impact of this error resulted in an 
understatement of both the "Revenues - Consumables" and "Consumables cost of revenues, exclusive of depreciation and 
amortization" line items in the Consolidated Statements of Operations for each of the quarters included in 2020 and for the 
quarters ended March 31, 2021, June 30, 2021 and September 30, 2021 and is shown below for those periods. The amounts 
reported above for the three months ended March 31, 2021 and 2020, the three months ended June 30, 2021 and 2020, the three 
months ended September 30, 2021 and 2020 and the three months ended December 31, 2020 have been restated for this error. 
There was no impact to operating income (loss), income (loss) before income taxes, net income (loss) or earnings (loss) to any 
of the 2021 or 2020 periods.

Note 25 - Subsequent Events

Unless disclosed elsewhere in the notes to the Consolidated Financial Statements, the following is the significant matter that 
occurred subsequent to December 31, 2021.

On February 25, 2022, the Company received $10.6 million in cash from Cabot (the "Cabot Payment") as a result of a change in 
control provision in the Supply Agreement (the "Change in Control"), which occurred as a result of the sale of Cabot by its 
parent, Cabot Corporation. Under the Change in Control, the Company received from Cabot full payment of all amounts 
outstanding under the Reclamation Reimbursement, payment of all unbilled amounts related to Specific Capital for 
expenditures incurred through February 28, 2022 and payment of additional Reclamation Costs (the "Cabot Reclamation 
Costs"). Under the Reclamation Contract, the Company is obligated to remit payment for the Cabot Reclamation Costs to the 
third party operator of Marshall Mine within a specified timeframe. The Company will account for the Cabot Payment in its 
March 31, 2022 quarter and does not anticipate any impacts to the Supply Agreement except as described above.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As required by Rule 13a‑15(b) under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), we have 
evaluated, under the supervision of and with the participation of our management, including our principal executive officer and 
principal financial officer, the effectiveness of the design and operation of our disclosure controls and procedures (as defined in 
Rules 13a‑15(e) and 15d‑15(e) under the Exchange Act) as of the end of the period covered by this annual report. Our 
disclosure controls and procedures are designed to ensure that information required to be disclosed in the reports that we file or 
submit under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s 
rules and forms.  Based upon this evaluation, our principal executive officer and principal financial officer concluded that our 
disclosure controls and procedures were not effective as of December 31, 2021 due to a material weakness in our internal 
control over financial reporting described below.

Management’s Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in 
Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Internal control over financial reporting is designed to provide 
reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements for 
external purposes in accordance with generally accepted accounting principles. The Company's internal control over financial 
reporting includes those policies and procedures that:

1. Pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and 

dispositions of our assets;

2. Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements 

in accordance with generally accepted accounting principles, and that receipts and expenditures of the Company are 
being made only in accordance with authorizations of our management and directors; and

3. 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 our financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, 
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate 
because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Under the supervision of, and with the participation of our management, including the principal executive officer and principal 
financial officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the 
framework and criteria established in Internal Control-Integrated Framework in 2013, issued by the Committee of Sponsoring 
Organizations of the Treadway Commission.  Based on this evaluation, our management concluded that our internal control 
over financial reporting was not effective as of December 31, 2021 due to the material weakness described below.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there 
is a reasonable possibility that a material misstatement of the Company's annual or interim financial statements will not be 
prevented or detected on a timely basis. 

During the assessment process, we identified deficiencies in the design and operation of controls over (1) the selection and 
application of accounting principles; (2) the monitoring of interpretative guidance of previously adopted accounting standards; 
and (3) the annual review of policies and procedures related to material accounts. These deficiencies in combination were 
evaluated as having a reasonable possibility that a material misstatement would not be prevented or detected on a timely basis 
resulting in a material weakness in our internal controls.

As a result of these deficiencies, as described in Note 2 to the consolidated financial statements included in Item 8. "Financial 
Statements and Supplementary Data," the Company identified and corrected immaterial errors in previously reported revenues 
due to freight revenue being improperly classified as consumables cost of revenue instead of consumables revenues. The 
material weakness did not result in a material misstatement of our historical consolidated financial statements.  

92

Management developed a plan to remediate the material weakness described above. Remediation efforts include (1) changes to 
the design of controls relating to the selection and application of accounting principles and the evaluation of changes in 
interpretative guidance relating to previously implemented accounting standards and (2) implementing an annual review of key 
accounting policies. The implementation of the remediation plan is in progress, and we expect to design and implement these 
changes in internal controls during the first half of fiscal year 2022.

Changes in Internal Control Over Financial Reporting

There has been no change in our internal control over financial reporting (as defined in Rules 13a‑15(f) and 15d‑15(f) under the 
Exchange Act) during the fourth quarter of 2021 that has materially affected, or is reasonably likely to materially affect, our 
internal control over financial reporting.

Report of Independent Auditors

To the Board of Managers and Members 
Tinuum Group, LLC

Report on the Audit of the Financial Statements

Opinion

We have audited the consolidated financial statements of Tinuum Group, LLC and its subsidiaries, which comprise the 
consolidated balance sheets as of December 31, 2021 and 2020, and the related consolidated statements of operations, 
members’ equity, and cash flows for the years then ended and the related notes to the consolidated financial statements.

In our opinion, the accompanying consolidated financial statements present fairly, in all material respects, the financial position 
of Tinuum Group, LLC and its subsidiaries as of December 31, 2021 and 2020, and the results of their operations and their cash 
flows for the years then ended in accordance with accounting principles generally accepted in the United States of America.

Basis for Opinion

We conducted our audits in accordance with auditing standards generally accepted in the United States of America (GAAS). 
Our responsibilities under those standards are further described in the Auditor’s Responsibilities for the Audit of the Financial 
Statements section of our report. We are required to be independent of Tinuum Group, LLC and its subsidiaries and to meet our 
other ethical responsibilities, in accordance with the relevant ethical requirements relating to our audits. We believe that the 
audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Responsibilities of Management for the Financial Statements

Management is responsible for the preparation and fair presentation of the consolidated financial statements in accordance with 
accounting principles generally accepted in the United States of America, and for the design, implementation, and maintenance 
of internal control relevant to the preparation and fair presentation of financial statements that are free from material 
misstatement, whether due to fraud or error.

In preparing the consolidated financial statements, management is required to evaluate whether there are conditions or events, 
considered in the aggregate, that raise substantial doubt about Tinuum Group, LLC and its subsidiaries’ ability to continue as a 
going concern within one year after the date that the consolidated financial statements are issued.

Auditor’s Responsibilities for the Audit of the Financial Statements

Our objectives are to obtain reasonable assurance about whether the consolidated financial statements as a whole are free from 
material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable 
assurance is a high level of assurance but is not absolute assurance and therefore is not a guarantee that an audit conducted in 
accordance with GAAS will always detect a material misstatement when it exists. The risk of not detecting a material 
misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, 
intentional omissions, misrepresentations, or the override of internal control. Misstatements are considered material if there is a 
substantial likelihood that, individually or in the aggregate, they would influence the judgment made by a reasonable user based 
on the consolidated financial statements.

In performing an audit in accordance with GAAS, we:

•

•

•

Exercise professional judgment and maintain professional skepticism throughout the audit.

Identify and assess the risks of material misstatement of the consolidated financial statements, whether due to fraud or 
error, and design and perform audit procedures responsive to those risks. Such procedures include examining, on a test 
basis, evidence regarding the amounts and disclosures in the consolidated financial statements.

Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate 
in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of Tinuum Group, LLC and 
its subsidiaries’ internal control. Accordingly, no such opinion is expressed.

101

•

•

Evaluate the appropriateness of accounting policies used and the reasonableness of significant accounting estimates 
made by management, as well as evaluate the overall presentation of the consolidated financial statements.

Conclude whether, in our judgment, there are conditions or events, considered in the aggregate, that raise substantial 
doubt about Tinuum Group, LLC and its subsidiaries’ ability to continue as a going concern for a reasonable period of 
time.

We are required to communicate with those charged with governance regarding, among other matters, the planned scope and 
timing of the audit, significant audit findings, and certain internal control–related matters that we identified during the audit.

Emphasis of Matter Regarding Going Concern
The accompanying consolidated financial statements have been prepared assuming that Tinuum Group, LLC and its 
subsidiaries will continue as a going concern. As discussed in Note 1 to the consolidated financial statements, with the 
expiration of the production tax credit (PTC) as of December 31, 2021 all third-party investor contracts have expired or been 
terminated and Tinuum Group, LLC and its subsidiaries have terminated reduced emissions fuel production as of December 31, 
2021, which has led to cash inflows ending in January 2022. To date, management has not developed an alternative business 
strategy that would support continued business operations. Given these events and conditions, substantial doubt exists about the 
Tinuum Group, LLC and its subsidiaries’ ability to continue as a going concern. Management’s evaluation of the events and 
conditions and management’s plans regarding these matters are also described in Note 1. The consolidated financial statements 
do not include any adjustments that might result from the outcome of this uncertainty. Our opinion is not modified with respect 
to this matter.

NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES

Tinuum Group, LLC (together with its subsidiaries, "Tinuum" or "TG" or the "Company") develops, manages, sells and leases 
facilities ("REF Facilities") used in the production and sale of reduced emissions fuel ("REF" or refined coal). The production 
and sale of REF via these REF Facilities qualifies for production tax credits that are available under Section 45 of the Internal 
Revenue  Code  ("PTCs").  The  value  of  the  PTC  is  adjusted  annually  based  on  inflation  adjustment  factors  published  in  the 
Federal  Register.  The  2021  and  2020  PTC  rates  were  $7.384  and  $7.301  per  ton  of  REF  produced,  respectively.  The  PTC 
period expired as of December 31, 2021 and as a result the Company has ceased production of REF.

Tinuum is owned 42.5% by ADA-ES, Inc. ("ADA"), 42.5% by NexGen Refined Coal, LLC ("NexGen") (collectively, Class A 
Members),  and  15%  by  GSFS  Investments  I  Corp.  ("GSFS"  or  the  "Class  B  Member").  ADA,  NexGen,  and  GSFS  are 
collectively referred to herein as the “Members.”

Tinuum  placed  in  service  28  REF  Facilities  prior  to  January  1,  2012.  Each  REF  Facility  has  demonstrated  the  required 
emissions reductions from the production of REF to qualify for PTCs. The REF produced at these REF Facilities is burned at 
coal-fired generation stations (the owner of which is a "Generator") and continues to qualify for PTCs for a period of 10 years 
following  the  applicable  placed  in  service  date.  The  28  REF  Facilities,  of  which  23  were  operating  during  the  year  ended 
December 31, 2021, no longer qualified for PTCs as of December 31, 2021. Two of the REF Facilities’ ability to produce PTCs 
ended during December 2019 since those two REF Facilities were placed in service in 2009.

REF Facilities were either sold to or were under lease with third-party investors ("TP Investors") who utilize the REF Facilities 
to produce REF (each of these REF Facilities is owned or leased by a “Producer Entity”). Some of the Producer Entities are 
owned or leased exclusively by a TP Investor and some are owned or leased by a TP Investor with some ownership percentage 
retained  by  the  Company.  The  REF  Facilities  are  located  at  coal-fired  generation  stations  throughout  the  United  States.  In 
instances  where  Tinuum  retains  certain  member  interests  in  a  Producer  Entity,  PTCs  generated  are  allocated  to  Tinuum  in 
proportion to its member interests and are therefore available for the benefit of Tinuum’s Members. As of December 31, 2020, 
23 REF Facilities had been sold or were under lease to TP Investors. For the year ended December 31, 2021, 23 REF Facilities 
were  owned  or  leased  by  TP  Investors  for  some  portion  of  the  year  ranging  from  six  to  nearly  twelve  months.  All  23  REF 
Facilities had ceased operations as of December 31, 2021. 

Tinuum  Services,  LLC  ("TS"),  operates  and  maintains  the  REF  Facilities  under  respective  operating  and  maintenance 
agreements. TS is owned 50% each by ADA and NexGen and is not consolidated with the accounts of Tinuum. TP Investors of 
REF Facilities pay TS, subject to certain limitations, a fee for procuring certain proprietary chemical additives, an operating fee 
for the production of REF, and for the other operating and maintenance costs associated with running the REF Facilities.

Basis of Presentation

The accompanying consolidated financial statements are presented in accordance with accounting principles generally accepted 
in  the  United  States  of  America  ("GAAP")  and  include  the  accounts  of  the  Company  and  several  variable  interest  entities 
("VIEs"), for which Tinuum is the primary beneficiary. An entity is referred to as a VIE if it meets any of the following criteria 
outlined  in  Accounting  Standard  Codification  810  -  Consolidation  ("ASC  810"),  which  are:  (i)  the  entity  has  equity  that  is 
insufficient to permit the entity to finance its activities without additional subordinated financial support from other parties; (ii) 
the entity has equity investors that, as a group, lack the characteristics of a controlling financial interest; or (iii) the entity is 
structured with non-substantive voting rights. 

The Company consolidates a VIE when it has both the power to direct the activities that most significantly impact the VIE’s 
economic performance and the obligation to absorb losses of the entity that could be potentially significant to the VIE (i.e., it is 
the primary beneficiary).

All intercompany balances and transactions have been eliminated in consolidation.

Going Concern

Currently, with the expiration of the PTCs as of December 31, 2021, all TP Investor contracts have expired or been terminated 
and  the  Company  has  terminated  REF  production,  which  has  led  to  cash  inflows  to  TG  ending  in  January  2022.  To  date, 
management has not developed an alternative business strategy that would support continued business operations. Management 
continues  to  engage  in  efforts  to  pursue  an  extension  of  the  PTC  period  by  the  U.S.  Congress,  though  at  present  no  such 

109

TINUUM GROUP, LLC AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
DECEMBER 31, 2021 and 2020
(in thousands)

extension  has  been  adopted.  In  the  event  of  a  PTC  extension  in  a  timely  manner,  management  would  investigate  any 
opportunity to continue REF production. 

Debt financing is no longer available to the Company. 

Management  has  budgeted,  and  is  planning,  to  reserve  enough  cash  from  the  final  cash  inflows  of  2021  and  2022  to  satisfy 
anticipated  remaining  liabilities  and  obligations.  These  cash  reserves  will  be  utilized  to  conduct  an  orderly  wind  down  of 
business operations. The decision to commence liquidation of the Company will be subject to approval by the Members. 

Management has concluded that these factors, in the aggregate, raise substantial doubt about the Company’s ability to continue 
as a going concern. The consolidated financial statements have been prepared on a basis which assumes the Company will be 
able to continue as a going concern and contemplates the realization of assets and satisfaction of liabilities in the normal course 
of business, and does not include any adjustments to reflect the possible future effects on the recoverability and classification of 
assets  or  the  amounts  and  classifications  of  liabilities  that  may  result  from  uncertainty  related  to  the  Company’s  ability  to 
continue as a going concern.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that 
affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial 
statements and the reported amounts of revenue and expenses during the reporting period. Management bases its estimates on 
historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Significant 
estimates include the estimated contingent revenues recognized related to revenues recognized at a point-in-time, assumptions 
associated with asset retirement obligations (“ARO”) and the final realization of remediation efforts, and the estimate for any 
outstanding contingent liabilities. Ultimate realization of assets and settlement of liabilities in the future could differ from these 
estimates. 

Cash and Cash Equivalents 

The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents. 
The carrying value approximates fair value due to the short-term nature of these instruments. The Company maintains its cash 
and cash equivalents in accounts with a local financial institution. These accounts at times may exceed federally insured limits. 
The  Company  has  not  experienced  any  losses  in  these  accounts  and  believes  it  is  not  exposed  to  any  significant  credit  risk 
related to cash and cash equivalents.

Accounts Receivable

Accounts receivable consist primarily of payments due from TP Investors that own or lease the REF Facilities. The carrying 
amount of accounts receivable may be reduced by a valuation allowance that reflects management's best estimate of amounts 
that  will  not  be  collected.  Under  the  Company’s  agreements,  interest  can  accrue  on  delinquent  balances.  No  interest  on 
delinquent balances was recorded for the years ended December 31, 2021 and 2020. Any allowance for doubtful accounts is 
based on management’s assessment of the collectability of specific customer accounts and the aging of the accounts receivable. 
If there is a deterioration of a major customer’s credit worthiness or actual defaults are higher than the historical experience, 
management’s estimates of the recoverability of amounts due to the Company could be adversely affected. As of December 31, 
2021 and 2020, no allowance for doubtful accounts was considered necessary.

Inventory

Inventory  is  comprised  primarily  of  feedstock  fuel  and  chemicals  used  in  the  production  and  sale  of  REF  at  REF  Facilities. 
Inventory is valued at the lower of cost or net realizable value using the average cost method. 

Fixed Assets

Fixed assets are stated at historical cost less accumulated depreciation and consist primarily of the REF Facilities and ancillary 
equipment,  including  major  additions  and  improvements.  Expenditures  for  major  improvements  are  capitalized,  while 
maintenance and repair costs that do not significantly improve the related asset or extend its useful life are charged to expense 
as incurred. For financial reporting purposes, depreciation is calculated using the straight-line method over the estimated useful 
lives of the assets ranging from 3 to 10 years. 

The Company records an ARO liability equal to the fair value of the estimated cost to retire a REF Facility. The ARO liability 
is  initially  recorded  in  the  period  in  which  the  obligation  meets  the  definition  of  a  liability,  which  is  generally  when  a  REF 

110

TINUUM GROUP, LLC AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
DECEMBER 31, 2021 and 2020
(in thousands)

Facility  is  installed  at  a  generation  station  ("Site").  The  ARO  liability  is  estimated  by  the  Company  based  on  legal  removal 
requirements, historical removal experience, and anticipated future inflation rates. When the liability is initially recorded, the 
Company increases the carrying amount of the related long-lived asset by an amount equal to the original liability. The liability 
is increased over time to reflect the change in its present value, and the capitalized cost is depreciated over the useful life of the 
related long-lived asset. The ARO liability is removed when the Company is relieved of its removal obligation due to either 
completion of the removal activities at a Site or a transfer of the responsibility for the REF Facility removal to a third party. The 
Company  reevaluates  the  adequacy  of  its  recorded  ARO  liability  at  least  annually.  Actual  costs  of  asset  retirements,  such  as 
removing  the  REF  Facility  from  a  Site  and  related  Site  restoration,  are  charged  against  the  related  liability.  Any  difference 
between costs incurred upon settlement of an ARO and the recorded liability is recognized in other expense as a gain or loss in 
the Company’s consolidated statements of operations.

Intangible Assets

Tinuum has two exclusive licenses from ADA for the patented and proprietary "CyClean™" and "M-45™" technologies related 
to  the  production  of  REF.  The  patents  underlying  the  CyClean™  technology  license  expire  beginning  in  2021;  however,  the 
license agreement includes potential future patents related to the technology. The costs associated with the exclusive CyClean™ 
license are included in other assets, net on the consolidated balance sheets and are being amortized over the useful economic 
life of the technology, or approximately 14 years, using the straight-line method. Amortization expense was $0 and $5 for each 
of the years ended December 31, 2021 and 2020, respectively.

Impairment of Long-Lived Assets

The  Company  reviews  long-lived  assets  for  impairment  whenever  events  or  changes  in  circumstances  indicate  the  carrying 
amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the 
carrying  amount  of  an  asset  to  future  undiscounted  net  cash  flows  expected  to  be  generated  by  the  asset.  If  such  assets  are 
considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the 
assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of carrying amount or fair value 
less costs to sell. As part of the Company’s on-going monitoring of its REF Facilities, the Company evaluated the REF Facility 
assets for potential impairment as of December 31, 2020. Given the expiration of the original PTC period, December 31, 2021, 
and the fact that the Company does not have an expectation of additional future cash flows associated with the REF Facilities 
beyond the PTC period, any REF Facilities that had not been invested by TP Investors have been considered to be impaired. 
Impairment  was  assessed  based  upon  the  future  undiscounted  cash  flows  of  each  REF  Facility  as  compared  to  its  net  book 
value. As a result, the Company recognized an impairment loss of $15 and $2,968 as of and for the years ended December 31, 
2021 and 2020, respectively.

Revenue Recognition

REF Facilities

The  Company  identifies  performance  obligations  by  reviewing  the  combination  of  customer  agreements  for  material  distinct 
goods and services. Goods and services are distinct when the customer can benefit from them on their own and the promises to 
transfer  these  items  are  separately  identifiable  from  other  promises  within  the  contract.  When  the  Company  is  contracted  to 
provide  a  single  promise  (an  integrated  system),  it  is  treated  as  a  single  performance  obligation  as  goods  and  services  are 
provided with the same pattern of transfer. The Company has identified the provision of the technology sublicense combined 
with the use of the REF Facility to be a single performance obligation.

REF Facility revenues are recognized based upon the type of contract with the TP Investor. Generally, the Company has three 
types  of  contracts  with  customers  (a)  Leases,  (b)  Member  Interest  Purchase  Agreements  ("MIPAs")  and  (c)  Asset  Purchase 
Agreements ("APAs"). In all instances the contracts relate to the use of the REF Facility and the related sublicensed patented 
technology which is necessary for each Producer Entity to produce REF utilizing the REF Facility. 

Depending  upon  the  agreement,  the  Company  may  receive  fixed  payments  or  a  combination  of  fixed  and  variable  payments 
over  the  contract  term.  Variable  payments  are  determined  based  upon  the  expected  amount  of  REF  production  during  the 
defined  period.  Certain  prepayments  are  received  upon  execution  of  TP  Investor  agreements.  Significant  judgments  and 
estimates  are  used  in  the  Company’s  revenue  policies.  Throughout  the  revenue  cycle,  the  Company  evaluates  contractual 
evidence, monitors performance and evaluates variable consideration changes. 

For  the  Leases  and  MIPAs,  revenue  is  recognized  “over  time”  using  the  output  method,  utilizing  actual  REF  production 
volumes. In these agreements where a prepayment is received, that amount is recorded as deferred revenue and is amortized 

111

TINUUM GROUP, LLC AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
DECEMBER 31, 2021 and 2020
(in thousands)

into  revenue  in  accordance  with  the  amortization  period  of  the  respective  TP  Investor  agreement.  Contingent  consideration 
associated  with  Leases  or  MIPAs  is  recorded  based  upon  actual  REF  production  volumes  achieved,  constrained  by  any 
contractual limitations or by production volumes that management estimates could occur.

Revenues recorded related to the APAs are recorded when the Company has completed delivery of the REF Facility and has 
transferred title and control of the REF Facility to the TP Investor. These revenues are recognized at a “point-in-time” based 
upon  the  net  present  value  of  the  expected  fixed  purchase  payments  plus  management’s  estimate  of  any  variable  payments 
associated with the sale. Additionally, since the payments are made quarterly over a time period exceeding one year, a financing 
component  exists  to  these  transactions.  For  the  years  ended  December  31,  2021  and  2020,  interest  recorded  related  to  these 
contracts was $541 and $1,619, respectively, and is recorded as interest income in the statement of operations. 

As  a  result  of  the  recording  of  APA  revenues  as  of  a  point-in-time,  future  cash  flows  will  be  received  according  to  the 
contractual payment schedules, but no future revenues, other than changes in estimates, will be recognized for these contracts. 
Changes  in  estimates  for  variable  consideration  can  occur  for  a  variety  of  reasons,  including  but  not  limited  to  (i)  annual 
inflation  adjustment  factors  being  different  from  what  was  originally  estimated  and  (ii)  changes  in  actual  versus  expected 
production volumes of REF. For the years ended December 31, 2021 and 2020, the impact of the change in estimate resulted in 
a decrease in revenues of $2,643 and $1,129, respectively. 

Generally, the REF Facility is collateral for the outstanding contract receivable balances recorded by Tinuum. 

The  Company  recognizes  a  contract  receivable  when  the  Company  transfers  control  of  a  REF  Facility  to  the  customer  in 
advance  of  receiving  consideration.  Contracts  with  variable  consideration  are  billed  quarterly  in  arrears,  once  production 
volumes are known, under similar payment terms. 

Reduced Emissions and Unrefined Fuel 

The  Company’s  consolidated  VIEs,  which  are  Producer  Entities,  purchase  and  take  title  to  feedstock  fuel  under  purchase 
agreements with each respective Generator or other supplier of feedstock fuel. Each Producer Entity purchases chemicals from 
third-party vendors and applies them to the feedstock fuel to produce REF utilizing the REF Facility. The REF is sold by the 
Producer Entities, under REF sale agreements, to a Generator or to another third party at the discretion of the manager of each 
Producer  Entity,  as  permitted  under  the  applicable  Generator  agreements.  The  Company  performs  REF  recertification  or 
redetermination testing periodically as required by Section 45 with respect to production and sale of REF at each of its REF 
Facilities. During the years ended December 31, 2021 and 2020, each of the Producer Entities sold all of its REF and unrefined 
fuel  (coal  untreated  but  part  of  the  REF  process)  to  third  parties  that  used  the  fuel  to  generate  electricity  and  recorded  such 
amounts as reduced emissions and unrefined fuel revenues.

Each VIE utilizes the combination of the REF Facility and the technology license to combine raw materials (feedstock coal and 
chemicals) to produce REF which is then sold as a separate manufactured product to its customer, the Generator. As a result, 
the Company recognizes both REF Facility revenues and reduced emissions and unrefined fuel on a gross basis. 

An accounts receivable balance represents the Company’s right to consideration that is unconditional and only the passage of 
time is required before payment of that consideration is due. No allowance for doubtful accounts related to accounts receivable 
balances or impairment of contract receivables has been recorded as of December 31, 2021 and 2020.

Deferred revenue is recognized when the Company receives consideration in advance of performance.

The Company disaggregates revenue based upon the revenue recognition methodology (over time vs. point-in-time). 

Taxes  assessed  by  a  governmental  agency  that  are  imposed  on  and  concurrent  with  a  specific  revenue  producing  transaction 
collected by the Company from a customer are excluded from revenues. 

Shipping and handling costs are not associated with Tinuum’s products and services and therefore are not included in revenues 
or costs of revenues. No amounts have been recorded for returns, refunds, or other similar obligations.

Income Taxes

The Company, with the consent of its Members, has elected to be taxed under applicable sections of federal and state income 
tax laws as a limited liability company treated as a partnership for income tax purposes. As a result of this election, no federal 
income  taxes  are  incurred  by  the  Company.  Instead,  the  Members  are  liable  for  income  taxes  on  their  pro  rata  share  of  the 
Company's income, deductions, losses, and credits. In certain states, the Company is taxed based upon shareholder equity or 
other enterprise considerations. In these instances, the Company records and pays the applicable tax directly to the state agency.

(in thousands)

One  of  the  Company’s  consolidated  VIEs  has  elected  to  be  a  C  corporation  for  federal  and  state  income  tax  purposes.  As  a 
result,  that  VIE’s  income  tax  provision  and  related  deferred  tax  assets  and  liabilities  are  included  within  the  consolidated 
financial statements. 

Deferred income taxes are provided for temporary differences arising from differences between the financial statement amount 
and tax basis of assets and liabilities existing at each balance sheet date, using enacted tax rates anticipated to be in effect when 
the related taxes are expected to be paid. A valuation allowance is established if it is more likely than not that a deferred tax 
asset  will  not  be  realized.  The  Company  includes  interest  and  penalties  related  to  state  tax  as  a  component  of  income  tax 
expense. 

The Company applies the requirement of ASC 740, Income Taxes, related to accounting for uncertain tax positions. 

In January 2021, the Company was notified that one of its consolidating VIEs was selected for audit by the IRS. Tinuum is the 
partnership representative and cooperated with the IRS audit requirements. The audit was completed by the IRS during 2021 
with no proposed adjustments.

Recent Accounting Pronouncements 

The  Company  does  not  believe  that  there  are  any  new  accounting  pronouncements  that  have  been  issued  that  might  have  a 
material impact on its financial position or results of operations.

NOTE 2 - FIXED ASSETS

Reduced Emissions Fuel Facilities 

Each  of  the  REF  Facilities  and  related  components  that  were  placed  in  service  by  the  Company  demonstrated  the  qualified 
emissions  reductions  to  qualify  for  PTCs.  REF  Facilities  are  stated  at  historical  cost.  Depreciation  is  calculated  using  the 
straight-line method over a 10 year period, commencing with the original placed in service date. All REF Facilities were fully 
depreciated as of December 31, 2021.

Furniture, Fixtures and Equipment

Furniture, fixtures, and equipment is comprised of office furniture, fixtures and office equipment, including those under finance 
leases. These assets are recorded at cost and depreciated using the straight-line method with estimated useful lives ranging from 
3 to 8 years.

The following table summarizes the components of gross and net carrying amounts for fixed assets as of December 31, 2021 
and 2020:

Depreciation expense was $24,101 and $28,175, for the years ended December 31, 2021 and 2020, respectively.

During 2021 the Company reevaluated certain REF Facility equipment for which an impairment reserve had been recognized in 
2020. Certain REF Facility equipment was either disposed of or sold, resulting in an adjustment to the impairment reserve.

Under  the  site  license  agreements  between  the  Producer  Entities  or  Tinuum  and  the  Generators,  Tinuum  may  be  required  to 
return the Site upon which the REF Facility is located to its original condition at the end of the applicable contract period. In 
instances where the applicable agreements place this responsibility on the Company, the Company has recorded a liability for 
an ARO equal to the fair value of the estimated cost to retire the REF Facility and return each Site to its original condition. The 
ARO  liability  was  estimated  by  the  Company  using  estimated  and  historical  facility  removal  costs  and  anticipated  future 
inflation  rates.  This  estimated  future  value  was  discounted  to  its  present  value  using  the  Company’s  credit-adjusted  risk-free

rate. The carrying value of the asset is depreciated on a straight-line basis over the remaining estimated life of the REF Facility 
asset  group.  The  ARO  liability  is  increased  over  time  to  reflect  the  change  in  its  present  value,  and  the  capitalized  cost  is 
depreciated  over  the  useful  life  of  the  site  license.  In  subsequent  periods,  the  Company  is  required  to  make  adjustments  to 
AROs  based  on  changes  in  the  estimated  fair  values  of  the  obligations.  Corresponding  increases  in  asset  book  values  are 
depreciated over the remaining useful life of the related site license. Uncertainties as to the probability, timing, or amount of 
cash flows associated with AROs may affect management’s estimates of fair value. For the years ended December 31, 2021 and 
2020, within operating expenses, the Company recorded $399 and $184 of accretion expense, respectively.

As discussed in Note 1, revenue is recognized when a performance obligation is satisfied. The Company’s contracts can contain 
both  fixed  and  variable  components  of  the  transaction  price.  Each  contract  is  evaluated  for  these  components  and  may  be 
determined to include fixed consideration, variable consideration and financing components as part of the overall transaction 
price. The Company receives payments from customers based upon specific payment schedules established under each contract. 
Payment  schedules  can  include  a  combination  of  prepayments,  fixed  payments  and  variable  payments,  based  upon  expected 
production volumes, and are generally made quarterly.

When a contract is determined to contain variable consideration, the transaction price is estimated using the expected value (i.e., 
the most likely amount method) to predict revenue for that contract. These variable amounts are estimated at contract inception 
based  upon  the  projected  REF  production  volumes  associated  with  the  specific  Generator  location.  Estimated  amounts  are 
included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not 
occur  when  the  uncertainty  associated  with  the  variable  consideration  is  resolved.  Estimates  of  variable  consideration  are 
estimated based upon contractual terms, historical experience and projected REF production volumes.

Nine REF Facility transactions with TP Investors are transactions with a related party as of December 31, 2021 and 2020. These 
transactions generally have terms that extend to the date ten years after the placed in service date for the particular REF Facility, 
subject  to  earlier  termination  by  the  TP  Investor  at  periodic  intervals  or  upon  the  occurrence  of  specified  events.  As  of 
December 31, 2021 all transactions with a related party TP Investor had been terminated. 

Under the various TP Investor agreements, Tinuum has committed to provide the REF Facility and the related sublicense for a 
term  as  identified  in  each  contract.  Most  of  the  agreements  expired  in  2021  or  will  expire  by  the  first  quarter  of  2022. 
Generally, payments are made quarterly to Tinuum on a net 10 to 30 days basis, in advance of the respective quarter.

Future REF Facility payments, including any eliminated in consolidation, are based on the 2021 levels of REF production and 
are $9,753 for 2022. 

In December 2019, the Company agreed to provide a future price concession to a significant customer. A portion of the price 
concession was provided via a note payable (“Customer Note”) under which the Company would make monthly principal and 
interest payments to the customer commencing in January 2020 and continuing through March 2021. The Customer Note was 
$27,000 and the Company recorded the amount as contract costs on the consolidated balance sheet and allocated the payments 
to  the  customer  as  a  reduction  to  the  transaction  price  of  the  existing  contracts  with  the  customer.  The  reduction  in  the 
transaction price was recorded monthly, commencing with the contract date of December 2019 through the end of the term of 
the payments of March 31, 2021. The reduction in the transaction price is recorded as production volumes are achieved (over 
time). For the years ended December 31, 2021 and 2020, the Company reduced revenues under this price concession contract 
by $5,226 and $20,903, respectively. 

In  certain  instances,  the  Company  employs  outside  parties  to  facilitate  the  commencement  of  a  Lease,  MIPA  or  APA 
transaction. Under these agreements, the Company typically pays the outside party a fee (“Fee”) relative to either the collection 
of revenues by the Company or the REF production volumes achieved. Under the Lease and MIPA transactions, any related 
contract costs are recorded as the production volumes or collection of revenues are achieved. These amounts are recorded as a 
component of cost of goods sold. Under the APA agreements, the Fees are capitalized as contract costs based on the estimated 
revenues  recognized  at  the  commencement  of  the  contract  and  are  amortized  as  a  reduction  of  revenue  over  the  period  of 
benefit. For the years ended December 31, 2021 and 2020, Fees included in contract costs on the consolidated balance sheet 
were $0 and $315, respectively. 

NOTE 5 - VARIABLE INTEREST ENTITIES

For the years ended December 31, 2021 and 2020, the Company consolidates nine entities (the “TG VIEs”) that were created as 
REF production companies. The operations include the purchase of feedstock fuel from a Generator, application of chemicals 
utilizing that Producer Entity’s REF Facility, and the subsequent sale of REF to the Generator. In all nine of the TG VIEs, CCS-
AE, LLC (“CCS-AE”), a subsidiary of the Company, or another Tinuum entity is the manager (“Managing Member”) and holds 
a 0.2% or 1.0% member interest, depending on the transaction. As the Managing Member of the TG VIEs, CCS-AE or Tinuum 
directs  the  activities  that  are  considered  most  significant  to  the  entities.  Based  upon  the  criteria  set  forth  in  ASC  810,  the 
Company has determined that it is the primary beneficiary in the TG VIEs for the years ended December 31, 2021 and 2020. As 
such, the financial results of the TG VIEs are consolidated with the results of the Company, and the results attributable to the 
other owners are presented as noncontrolling interests within the consolidated financial statements. 

Creditors of the TG VIEs have no recourse against the general credit of the Company (outside of its member interest or specific 
guarantee obligations) and the assets of the Company are not collateral for any TG VIE obligations. The operations of all nine 
entities are financed through capital calls of the respective members in proportion to their member interests. In the event that a 
member  defaults  on  a  capital  call  request  made  by  the  Managing  Member,  the  Managing  Member  may  (i)  withhold 
distributions payable to the defaulting member or sue for the amount due, and/or (ii) elect to transfer the defaulting member’s 
interest to a separate legal entity controlled by the Managing Member, or (iii) suspend operations of the REF Facility. In certain 
instances, the TP Investor has the ability to put, and Tinuum has the ability to call, the other member interests at a purchase 
price equal to fair market value.

Under the provisions of certain of the TG VIEs’ various agreements, including the leases of REF Facilities or the partnership 
operations  of  the  TG  VIEs,  the  agreements  terminate  during  time  periods  ranging  from  the  fourth  quarter  of  2021  through 
December 31, 2022, unless terminated earlier by written consent of the members.

Under certain of the TG VIE agreements, capital call limitations exist, limiting the amount of capital calls if certain operational 
costs are exceeded.

NOTE 6 - NOTES PAYABLE

Line of Credit

In September 2019, the 2013 Revolver (“Revolver”) with BOK Financial (“BOK”), was amended and replaced with the Fifth 
Amendment to the Revolver (“Fifth Amendment”). The Fifth Amendment expired on December 31, 2020 and was not renewed 
and all balances were fully repaid. Under the Fifth Amendment, prior to expiration, the available borrowing limit was:

The Fifth Amendment required any outstanding borrowings to be fully repaid for a period of fifteen consecutive days during 
two non-consecutive calendar quarters.

Amounts outstanding under the Fifth Amendment were repaid at the option of the Company. Any undrawn balance during the 
years ended December 31, 2020, was subject to a quarterly unused facility fee in the amount of 0.826% annually. Interest on 
outstanding balances was payable monthly and was accrued at the greater of 5.5% per annum or the prime rate (as defined in 
the agreement) plus 1.0%.

The Fifth Amendment was collateralized by the assets of the Company and the equity interests and proceeds related to such 
equity  interests  of  each  material  subsidiary  owned  by  the  Company.  The  Fifth  Amendment  was  also  collateralized  by  the 
Company’s deposit accounts held at BOK. These accounts were not restricted by the Fifth Amendment.

Customer Note 

As mentioned in Note 4, in December 2019, the Company agreed to provide a future price concession to a significant customer 
via a Customer Note. The Company made monthly principal and interest payments to the customer. Payments commenced in 
January  2020  and  extended  through  March  2021,  when  the  Customer  Note  was  fully  repaid.  As  of  December  31,  2020,  the 
Customer Note balance was $5,400. The Customer Note bears interest at 8% per annum. 

Under the Customer Note, Tinuum has agreed to maintain a Cash Reserve Account of $3,000, to limit additional indebtedness 
to $7,000 (plus amounts to finance Company insurance premiums plus a maximum of $500 for finance leases) and to maintain 
compliance  with  certain  loan  covenants.  At  December  31,  2020,  the  Company  was  in  compliance  with  the  Customer  Note 
covenants.

Secured Promissory Note 

In  February  2014,  a  VIE  consolidated  into  the  consolidated  financial  statements  of  the  Company,  entered  into  an  $11,000 
secured promissory note (the “Note”) with a Generator from which it purchases feedstock fuel, and to which it sells reduced 
emissions and unrefined fuel on a monthly basis. The purpose of the Note is to finance the purchases of feedstock fuel from the 
Generator. The amount of principal and interest owed is dependent upon the amount of feedstock fuel purchased and reduced 
emissions and unrefined fuel sold between the two parties and is net settled on a monthly basis. The Note was collateralized by 
the feedstock fuel inventory. 

The Note bears interest at a per annum rate equal to the short-term applicable federal rate announced by the IRS in December of 
each year. The interest rate for the years ended December 31, 2021 and 2020 was 0.14% and 1.60% per annum, respectively. 
Interest is payable quarterly in arrears.

All outstanding amounts owed under the Note are due and payable on the earlier of December 31, 2021 or the termination or 
expiration of the Feedstock Coal Purchase Agreement between the TG VIE and the Generator. The Note was fully repaid as of 
December 31, 2021.

As of December 31, 2021 and 2020, respectively, the outstanding balance on the Note was $0 and $4,327 with interest payable 
of $0 and $16, respectively.

In  June  2018,  a  second  VIE  consolidated  into  the  consolidated  financial  statements  of  the  Company,  entered  into  an  $1,986 
secured promissory note (“2018 Note”) with a Generator to fund the initial purchase of feedstock fuel. The 2018 Note bears 
interest at a per annum rate equal to the mid-term applicable federal rate announced by the IRS in December of each year. The 
rate  was  0.48%  and  1.67%  for  the  years  ended  December  31,  2021  and  2020,  respectively.  Interest  is  payable  quarterly  in 
arrears. The 2018 Note is collateralized by the feedstock fuel inventory. 

All outstanding amounts owed under the 2018 Note are due and payable on the earlier of December 31, 2025, or the termination 
or expiration of the Feedstock Coal Purchase Agreement between the Company and the Generator.

NOTE 7 - MEMBERS’ EQUITY 

Under the Class B Unit Purchase Agreement (“Class B Agreement”) with GSFS, which was entered into upon the amendment 
and  restatement  of  the  Tinuum  Operating  Agreement  in  2011,  ADA  and  NexGen  each  entered  into  a  limited  guarantee 
agreement  under  which  the  parties  are  obligated  to  guarantee  performance  by  Tinuum  of  its  obligations  to  indemnify  GSFS 
against certain losses it may suffer as a result of inaccuracies or breach in representations and covenants related to the Class B 
Agreement or REF Facilities’ lease agreements with GSFS affiliates. ADA and NexGen entered into a contribution agreement 
where,  in  the  event  of  such  a  breach,  they  have  agreed  to  contribute  their  pro  rata  share  of  any  amounts  under  the  limited 
guarantee.

The  Class  B  units  were  considered  conditionally  redeemable  as  specified  in  the  Second  Amended  and  Restated  Operating 
Agreement and the Class B Agreement. Upon satisfaction of the redemption criteria in 2018, GSFS continues to own the Class 
B  units  which  have  no  further  capital  call  requirements  and  have  limited  voting  rights.  In  September  2019,  the  Second 
Amended and Restated Operating Agreement was amended to eliminate the preferential redemption provisions for the Class B 
shares and simultaneously reallocated certain tax attributes between the Class A and B Members. 

The Company had the following classes and percentages of Member units issued and outstanding at December 31, 2021 and 
2020.

During the years ended December 31, 2021 and 2020, the Company has concluded that there are no significant uncertain tax 
positions  that  would  require  recognition  or  disclosure  in  the  financial  statements.  As  of  December  31,  2021  and  2020,  the 
Company made no provision for interest or penalties related to uncertain positions.

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities 
for financial reporting purposes and the amounts for income tax purposes related to one of the Company’s consolidated VIEs. 
Under a tax sharing agreement with the specific TP Investor of this VIE, the deferred tax assets are allocated specifically to the 
TP Investor and are not for the benefit of Tinuum or its members. On a quarterly basis, the TP Investor provides a cash payment 
to the VIE for the prior quarter’s tax benefits generated, generally production tax credits and net operating losses. As a result, 
the quarterly estimated funding is presented as an income tax receivable in the consolidated balance sheets. As of December 31, 
2021, an income tax payable is being presented as the estimated funding exceeded the actual TP investor provision. 

The income tax payable as of December 31, 2021 is included in accrued liabilities in the consolidated balance sheets and

NOTE 10 - COMMITMENTS

Purchase Commitments

In  November  2011,  Tinuum  entered  into  a  technology  licensing  agreement  with  ADA  whereby  Tinuum  agreed  to  pay  ADA 
royalties based on a percentage of operating income from REF production at REF Facilities that utilize the M-45™ technology. 
During  the  years  ended  December  31,  2021  and  2020,  respectively,  the  Company  recognized  royalty  expense  under  cost  of 
sales in the amounts of $14,354 and $13,440 respectively.

In  December  2015  the  Company  was  assigned,  by  TS,  a  Master  Supply  Agreement  with  a  chemical  vendor.  Under  the 
agreement  the  Company  had  a  commitment  commencing  January  1,  2015,  for  minimum  purchase  quantities  of  the  specified 
chemical  that  if  not  achieved  would  require  a  shortfall  payment  amount  (“Shortfall”)  to  be  paid  to  the  vendor  on  a  monthly 
basis.  Any  Shortfall  payment  required  would  be  applied  to  future  chemical  purchases  once  certain  minimum  volume  levels 
were achieved. In 2018 an agreement was reached to further amend the Master Supply Agreement and the Company made an 
additional prepayment of $8,187 resulting in a total prepaid amount of $17,755 on deposit with the vendor as of December 31, 
2019. Beginning in August 2020, the Company started utilizing the prepaid deposit balance through ongoing chemical usage. 
The  prepaid  deposit  balance  was  fully  utilized  as  of  December  31,  2021  and  therefore  the  balance  was  $0  at  December  31, 
2021.  As  of  December  31,  2020,  the  balance  was  $10,632  and  was  included  within  other  current  assets  in  the  Company’s 
consolidated balance sheets. 

Retention Compensation

It has been an ongoing practice of the Company to provide severance payments to employees that are involuntarily terminated 
for reasons other than for cause. In anticipation of the wind down of operations expected by 2022, the Company has formalized 
that  practice  into  a  retention  compensation  program.  The  purpose  of  the  program  is  to  incent  employees  to  remain  with  the 
Company through the wind down dates necessary for the successful cessation of the Company. Certain executive employees 
have contracts that do not have a defined retention date but provide for severance payment provisions equivalent to one year of 
base salary that only become due and payable upon a decision by the Board of Managers to terminate an executive other than 
for cause. The potential estimated liability under these contracts is approximately $750. All non-executive employees have a 
retention  bonus  agreement  with  a  defined  dollar  amount  that  is  payable  by  the  Company  upon  the  earlier  of  the  Company’s 
initiation  of  an  involuntary  termination  or  the  employee  remaining  with  the  Company  until  the  defined  retention  date  within 
their agreement. Any employees electing to voluntarily terminate employment with the Company prior to their defined retention 
date will forfeit their retention bonus amount. Compensation expense of $3,116 and $2,048 was recognized for the years ended 
December 31, 2021 and 2020, respectively. A remaining liability of $3,613 is recorded and of this amount $1,835 is included in 
other current liabilities for TG employees and $1,778 is in the related party payables related to TS employees with retention 
dates in 2022. 

401k Profit Sharing Plan and Other Benefits 

The Company offers a defined contribution and profit sharing plan (the “Plan”) to employees who are over 18 years of age and 
have been employed by the Company for more than 30 days. Employees can deposit up to 80% of their eligible pay up to the 
statutory limit in the Plan. The Company contributes 3% of employees’ eligible pay to the Plan as safe harbor contributions and 
an  additional  matching  contribution  equivalent  to  50%  of  the  first  6%  of  employee  contributions.  Company  contributions

NOTE 11 - CONCENTRATIONS 

The Company’s operations were dependent upon TP Investors leasing or purchasing REF Facilities. Further, under the terms of 
the various TP Investor agreements, the agreements were subject to termination or modification by the TP Investor at periodic 
intervals or upon the occurrence of specified events which included amendments to Section 45 of the Internal Revenue Code. 
The termination or modification of all or a material portion of any TP Investor agreements would have had a significant adverse 
impact on the Company’s future operations and financial condition.  

Additionally, the production and sale of REF was dependent upon the plant operations of specific generating stations where the 
REF Facilities were located. Production at these locations could have been impacted by the demand for electricity, the amount 
of  fuel  burned  by  the  utility  to  produce  electricity,  disruptions  due  to  foreseen  or  unforeseen  plant  outages,  or  changes  in 
government regulations related to electricity generation or coal burning activities.  

Certain  of  the  chemicals  utilized  by  the  Company  to  produce  REF  were  available  from  a  limited  number  of  vendors  in  the 
United  States.  The  Company's  operations  could  have  been  materially  and  adversely  affected  if  the  Company  encountered 
difficulty procuring these chemicals, the quality of available chemicals deteriorated or there were significant price increases for 
the chemicals.
