In Everything We Do.

TECHNOLOGY
In Everything We Do.

Technology is part of CARBO’s DNA.

Innovative technology enabled CARBO to become the world’s pioneer of ceramic 

proppant. Technology is now empowering CARBO’s transformation, resulting in  

a broad portfolio of unparalleled, value-added products and services.

CARBO’s industrial sector is a growing contributor with an array of products 

developed to improve our clients’ processes, performance, product quality and 

workplace safety.

CARBO’s environmental business is leveraging its proprietary technology to create 

a portfolio of products including site protection, spill prevention and containment 

solutions for clients in a diverse range of industries.

CARBO is not the same company today as it was a few short years ago. 

Implementing our transformation strategy, the company is becoming more 

diversified, balanced and able to deliver a stronger performance under varied 

market conditions. One thing remains constant: 

There is Technology In Everything We Do.

To Our Shareholders, Clients and Employees:

In 2018, CARBO® successfully continued to execute its transformation strategy to 

diversify its business and reduce its historic reliance on the cyclical oil and gas industry. 

Through effective execution of this strategy, CARBO generated increased revenue and a  

139 percent incremental gross margin despite the downturn in the oil and gas markets  

in the second half of 2018.

THE POWER OF TRANSFORMATION

For most of CARBO’s history, base ceramic proppant has been the foundation of the 

company. As recently as 2014, it provided approximately 80 percent of our consolidated 

revenue; however, the company was especially vulnerable to swings in oilfield activity 

and changing industry trends.

With the development of industry-leading technology, strategically diversifying our 

business as well as adding revenue streams, we continue to build a more stable, multi-

faceted company. Base ceramic remains important, with contributions to consolidated 

revenue in 2018 at approximately 20 percent, while our growing industrial sector and 

environmental business contributed nearly a quarter of consolidated revenue. 

FINANCIAL HIGHLIGHTS

CARBO revenue for 2018 was $210.7 million, an increase of 12 percent compared to 2017. 

The highlight of our transformation strategy was double-digit revenue growth in our 

technology-driven oilfield products, our industrial sector and environmental business.

Continuing to effectively reduce costs and implement strategic structural changes, we 

sold our Millen, Georgia, manufacturing facility, and were able to lease under-utilized 

assets to other companies, which generated cash and recouped costs. 

Our balance sheet remains strong. As of December 31, 2018, the company had cash  

and cash equivalents and restricted cash totaling $83.3 million, with $92.0 million of 

debt. We expect to use some of this cash to pay down debt during 2019. In addition,  

we are always looking for potential technology opportunities to enhance our  

transformation strategy.

TECHNOLOGY DRIVES OILFIELD PERFORMANCE 

Revenue from our oil and gas sector, excluding prior year Russia proppant sales, 

increased 14 percent in 2018 compared to 2017, comprising approximately 78 percent  

of consolidated revenue.

CARBO’s technology-rich oilfield products continue to grow and differentiate the 

company. Technology-driven products revenue increased 15 percent in 2018, led 

primarily by KRYPTOSPHERE® ultra-conductive proppant, CARBOAIR® ultra low-density 

proppant with exceptional transport characteristics, and CARBONRT®, our non-

radioactive tracer. 

A highlight of 2018 was the commercialization of SALTGUARD®, one of our unique 

production assurance technologies. SCALEGUARD® and SALTGUARD provide a long-term 

release of chemicals that prevent build-up of deposits which can restrict production and 

increase well work-over costs. 

STRATAGEN® consulting revenue increased 38 percent year-on-year. FRACPRO® fracture 

simulation software revenue increased 22 percent, primarily driven by new client growth.

INDUSTRIAL TRANSFORMATION AND GROWTH

The transformation of our industrial sector was evident, with continued substantial 

growth in 2018 and a revenue increase of 24 percent. New industrial ceramic products 

were introduced to the portfolio, leveraging our technology by developing solutions 

that address specific industrial challenges while opening new market segments. The 

technical sales force was increased to support these products, resulting in the significant 

addition of new clients.

Increased sales of ACCUCAST® were driven by metal casting foundries conducting full 

conversions from sand to ceramic casting media in response to new OSHA silica dust 

permissible exposure limits for respirable crystalline silica. Converting completely from 

sand to ACCUCAST provides employee safety, eliminates the costly investment needed 

to comply with mandated OSHA regulations, and produces higher quality castings. 

We continued to develop new CARBOGRIND® products to provide the mining industry 

with a complete portfolio for fine and ultra-fine grinding applications. 

With one treatment during fracturing 
operations, SCALEGUARD technology  
delivers long-term production assurance.

ACCUCAST ceramic casting media can 
improve casting quality, reduce media  
costs and enhance workplace safety.

EXPANDING THE ENVIRONMENTAL ARENA 

ASSETGUARD™, our environmental business, increased revenue by 39 percent in 

2018 and comprised approximately 15 percent of total consolidated revenue. We 

experienced strong product sales to diverse distributors and end-users, including  

food and beverage, retail, medical and municipalities, while continuing to provide 

valuable spill prevention and containment solutions in the oilfield.

GROUNDGUARD®, our impermeable liner technology that protects any industrial, 

agricultural or commercial site against leaks or spills of fluids, grew 69 percent.

MANUFACTURING FACILITIES OPTIMIZATION  
AND A UNIQUE OPPORTUNITY

In 2018, we continued to find new opportunities to utilize our plant assets to generate 

cash flow. Our state-of-the-art facilities are an attractive means for third parties to add 

manufacturing capacity. Contract manufacturing clients include companies in the oil 

and gas, manufacturing, construction and agriculture industries.

We are excited about becoming a minority owner in PicOnyx, Inc. They have 

developed M-Tone™, a new family of functional pigments for the plastics, paints, ink, 

coatings and adhesives markets. M-Tone will provide a superior, environmentally safe 

alternative to carbon black. CARBO will manufacture M-Tone at one of our facilities.

CONTINUING THE TRANSFORMATION

We are pleased with the results achieved to date with our transformation strategy.  

By broadening our businesses, we will continue to mitigate the impact of swings in 

oilfield activity.

We expect continued growth in our industrial sector and environmental business as 

we continue to diversify into other end markets. In the oilfield sector, industry analysts 

expect lower activity that may impact revenue for the first half of 2019.

STRATAGEN engineers provide onsite 
consulting that enables clients to optimize 
fracture designs, execution and field 
development. 

• 

In our oilfield sector, we anticipate increased market penetration of CARBONRT, 

KRYPTOSPHERE and the GUARD® family of products, as well as FRACPRO software. 

Internationally, demand for our higher-margin, technology-rich products continues  

to increase in South America, Europe, Africa and the Middle East. 

•  We project that our industrial sector will again produce double-digit revenue growth 

along with strong results in 2019. Our industrial ceramic client list is expanding globally 

as we develop new markets while continuing to expand our existing markets.

•  We project that our environmental business will continue double-digit revenue 

growth in 2019 through expanded markets, introduction of new products,  

increased geographical footprint, and innovative sales and distribution strategies.

•  PicOnyx, Inc. is off to a good start. M-Tone pigment should be commercialized during 

the first half of 2019, and we expect production to ramp up over the course of the year.

•  We are pursuing a number of contract manufacturing opportunities and expect  

this sector to grow in revenue by expanding the types of products we produce for  

our clients.

CARBO is a versatile company that identifies advantageous opportunities, develops 

optimal strategies, and deploys targeted technologies that will lead to continued 

profitable growth.

As we move forward into 2019, I have the utmost confidence in our CARBO team 

members and our Board of Directors to continue to successfully execute our 

transformation strategy.

Sincerely,

Our environmental products, such as the 
patented TANKGUARD™ base, are engineered 
for outstanding performance, maintenance-
free durability and lightweight construction 
for easy installation.

Our industrial portfolio has expanded to 70 
products developed for specific applications 
in the casting and grinding markets.

Business

General

PART I

CARBO  Ceramics  Inc.  (“we,”  “us,”  “our”  or  our  “Company”)  is  a  global  technology  company  that  provides  products  and 
services to the oil and gas, industrial, and environmental markets to enhance value for its clients.  The Company was incorporated in 
1987 in Delaware.  As used herein, “Company”, “CARBO”, “we”, “our” and “us” may refer to the Company and/or its consolidated 
subsidiaries.

The Company conducts its business within two operating segments: 1) Oilfield and Industrial Technologies and Services and 2) 
Environmental Technologies and Services.  Financial information about reportable operating segments is provided in Note 14 to the 
Company’s Consolidated Financial Statements.  

The Company’s Oilfield and Industrial Technologies and Services segment manufactures and sells ceramic technology products 
and services, base ceramic proppant and frac sand for both the oilfield and industrial sectors.  The products have different technology 
features and product characteristics, which vary based on the application for which they are intended to be used.  The various ceramic 
products’ manufacturing processes are similar.

Oilfield  ceramic  technology  products,  base  ceramic  proppant  and  frac  sand  proppant  are  manufactured  and  sold  to  pressure 
pumping companies and oil and gas operators for use in the hydraulic fracturing of natural gas and oil wells.  Hydraulic fracturing is 
the most widely used method of increasing production from oil and natural gas wells.  The hydraulic fracturing process consists of 
pumping fluids down a natural gas or oil well at pressures sufficient to create fractures in the hydrocarbon-bearing rock formation.  A 
granular  material,  called  proppant,  is  suspended  and  transported  in  the  fluid  and  fills  the  fracture,  “propping”  it  open  once  high-
pressure pumping stops.  The proppant filled fracture creates a conductive channel through which the hydrocarbons can flow more 
freely from the formation to the well and then to the surface.

There are three primary types of proppant that can be utilized in the hydraulic fracturing process: sand, resin coated sand and 
ceramic.    Sand  is  the  least  expensive  proppant,  resin-coated  sand  is  more  expensive  and  ceramic  proppant  is  typically  the  most 
expensive.  We believe that the higher initial cost of ceramic proppant is justified by the fact that its use in certain well conditions 
typically  results  in  an  increase  in  the  production  rate  of  oil  and  natural  gas,  an  increase  in  the  total  oil  or  natural  gas  that  can  be 
recovered from the well and, consequently, an increase in cash flow for the operators of the well.  The increased production rates are 
primarily attributable to the higher strength and more uniform size and shape of ceramic proppant versus alternative materials.  We are 
one of the world’s largest suppliers of ceramic proppant.

We manufacture various distinct ceramic proppants.  Our technology suite of ceramic proppants include the following:

KRYPTOSPHERE® HD is a high-performance mono-mesh ceramic proppant engineered to deliver increased conductivity and 
durability in the highest closure stress wells.  In challenging, high-cost environments such as ultra-deep wells, KRYPTOSPHERE HD 
retains its integrity and enables greater production and Estimated Ultimate Recovery (“EUR”) from the reservoir.

KRYPTOSPHERE XT meets client needs for a lower density proppant than KRYPTOSPHERE HD, and the closure stress is 
lower than the application for KRYPTOSPHERE HD, but higher than KRYPTOSPHERE LD. Commercialization occurred in January 
2019.

KRYPTOSPHERE  LD  meets  client  needs  for  a  lower  density  proppant  than  KRYPTOSPHERE  HD,  yet  has  similar 

characteristics and conductivity in high stress wells.

SCALEGUARD®  is  a  porous  ceramic  proppant  that  is  infused  with  scale-inhibiting  chemicals  and  placed  throughout  the 
fracture as part of the hydraulic fracturing process.  The infused scale inhibitor in SCALEGUARD is designed to be released into the 
fracture only on contact with water and thereby reduce or eliminate expensive remedial maintenance programs.  SALTGUARD® was 
commercialized in 2018.  The product has been shown to prevent salt build up in oil and gas wells.

Our  FUSION®  technology  improves  well  productivity  by  forming  a  stable,  high-permeability  proppant  pack  that  prevents 

proppant washout from the non-compressive annulus and near-wellbore areas.

1

CARBOAIR® is a high-transport, ultra-low-density ceramic proppant technology that has been developed primarily to increase 
production and EUR from slickwater fracturing operations. The technology enables exploration and production (“E&P”) operators to 
avoid the introduction of gel into their fracs while improving reservoir contact and fracture conductivity.

NANOMITE™ C is a micro mesh ceramic proppant which is engineered to prop natural fractures which are opened during the 
hydraulic fracturing process which would not normally be propped open. The resulting propped reservoir contact increases and the 
EUR is increased.

Our RPM relative permeability modification technology is engineered to alter the wettability of proppant to neutral, preventing 
the  retention  of  water-based  fluid  in  the  proppant  pack.  As  a  result,  RPM  technology  increases  the  effective  fracture  length, 
conductivity and permeability of the pack to hydrocarbons, leading to higher production and increased ultimate recovery.

In  addition,  we  manufacture  CARBONRT®,  a  detectable  proppant  that  utilizes  a  non-radioactive  tracer  material  to  assist 
operators in determining the locations of fractures in a natural gas or oil well.  This tracer is added to the proppant granules during the 
manufacturing process, and can be added to most of the types of proppant that the Company sells.

Our base ceramic suite of products include:

CARBOLITE®  and  CARBOECONOPROP®  are  low-density  ceramic  proppants.    CARBOLITE®  is  used  in  medium  depth  oil 
and  natural  gas  wells,  where  higher  production  rates  can  be  achieved  due  to  the  product’s  uniform  size  and  spherical  shape.  
CARBOECONOPROP  was  introduced  to  provide  a  lower  cost  ceramic  to  compete  more  directly  with  resin-coated  sand  and  sand 
proppant.

We produce resin-coated ceramic (CARBOBOND LITE®), which addresses a niche market in which oil and natural gas wells 

are subject to the risk of proppant flow-back.

Our  sand  proppants  include  CARBO  NORTHERN-WHITE,  which  is  a  frac  sand  that  is  used  by  operators  that  still  value 

quality, but do not wish to pay the higher costs associated with ceramic or resin-coated proppants.

Our  industrial  ceramic  technology  products  are  manufactured  and  sold  to  industrial  companies  globally.    These  products  are 

designed for use in various industrial technology applications, including but not limited to casting and milling.

Our industrial sand products are manufactured and sold to industrial companies.  These products are designed for use in various 

industrial applications.

ACCUCAST®  is  a  high-performance  ceramic  casting  media  that  is  engineered  for  precision  performance.    Outperforming 
specialty and silica sand products, their unique thermal, physical and chemical properties reduce media consumption and costs, lower 
production defects and reduce energy consumption.

CARBOGRIND® is a high-performance ceramic media that improves grinding efficiency while lowering operational costs for 
clients.  The durability of our ceramic grinding media results in longer product life, while the uniform size and spherical shape add 
efficiency to grinding operations and reduce wear on the mechanical parts of milling equipment.

The  CARBOBEAD™  family  of  high-performance  ceramic  media  technologies  are  engineered  to  provide  economic,  Health, 
Safety and Environmental (HSE) and performance advantages in a wide variety of industrial applications compared to sand and other 
competing synthetic media types.

We also produce industrial products at our manufacturing facilities for third parties under tolling arrangements.  These products 
have been used in industrial, agricultural and oilfield applications.  Contract manufacturing has led to increased revenue generation.  
We continue to develop additional opportunities within the industrial, agricultural and oil and gas industries to grow revenue, and to 
reduce our plant’s slowing and idling costs.

Through  our  wholly-owned  subsidiary  StrataGen,  Inc.,  we  promote  increased  production  and  EUR  of  oil  and  natural  gas  by 
selling a widely used fracture stimulation software under the brand FracPro®, and providing fracture design and consulting services to 
oil and natural gas E&P companies under the brand StrataGen®.

2

FracPro  provides  a  suite  of  stimulation  software  solutions  used  for  designing  fracture  treatments  and  for  on-site  real-time 
analysis.    Use  of  FracPro  enables  our  clients  to  optimize  stimulation  jobs  to  enhance  oil  and  gas  production.    FracPro  has  been 
integrated with third-party reservoir simulation software, furthering its reach and utility.

The  StrataGen  consulting  team  works  with  operators  around  the  world  to  help  optimize  well  placement,  fracture  treatment 
design and production enhancement.  The broad range of expertise of the StrataGen consultants includes: fracture treatment design; 
completion support; on-site treatment supervision; quality control; post-treatment evaluation and optimization; reservoir and fracture 
studies; rock mechanics and software application and training.  

Our Environmental Technologies and Services segment is intended to protect operators’ assets, minimize environmental risks 
and  lower  lease  operating  expense  (“LOE”).    Asset  Guard  Products  Inc.  (“AGPI”),  the  only  wholly-owned  subsidiary  of  ours  to 
operate  in  this  segment,  provides  spill  prevention,  containment  and  countermeasure  systems  for  the  oil  and  gas  and  industrial 
industries.   AGPI uses proprietary technology to make products designed to enable its clients to extend the life of their storage assets, 
reduce the potential for hydrocarbon spills and provide containment of stored materials.  

Current demand for proppant is extremely dynamic.  Most of our oilfield products and services depend primarily on the supply 
of  and  demand  for  oil  and  natural  gas,  as  well  as  on  the  number  of  natural  gas  and  oil  wells  drilled,  completed  or  re-completed 
worldwide.  More specifically, the demand for most of our products and services is dependent on the number of oil and natural gas 
wells  that  are  hydraulically  fractured  to  stimulate  production.    The  demand  for  our  products  and  services  is  also  dependent  on  the 
commodity price of oil and natural gas, and lower commodity prices result in fewer purchases of our premium products.  In addition, 
our results of operations are also significantly affected by a host of other factors, including but not limited to (a) rig counts, (b) well 
completions  activity,  which  is  not  necessarily  correlated  with  rig  count,  (c)  customer  preferences,  (d)  new  product  and  technology 
adoption,  (e)  imports  and  competition,  (f)  changes  in  the  product  mix  of  what  we  sell,  (g)  costs  of  developing  our  products  and 
services and running our business, and (h) changes in our strategy and execution.  

During the year ended December 31, 2018, we generated approximately 81% of our consolidated revenues in the United States 

and 19% in international markets.

Competition

As the demand for ceramic proppant (including proppant produced by us) continued to be negatively impacted in 2018 by the 
severe decline in the oil and natural gas industry, the number of domestic and international competitors in the marketplace continued 
to decrease, and many of our competitors have shut down plants and/or reduced production.  However, we do not have full visibility 
as  to  the  extent  or  duration  of  these  shut-downs  and  reductions.    One  of  our  worldwide  proppant  competitors  is  Saint-Gobain 
Proppants (“Saint-Gobain”).  Saint-Gobain is a division of Compagnie de Saint-Gobain, a large French glass and materials company.  
Saint-Gobain manufactures a variety of ceramic proppants that it markets in competition with some of our products.  Saint-Gobain’s 
primary  manufacturing  facilities  are  located  in  Bauxite,  Arkansas.    Saint-Gobain  also  manufactures  ceramic  proppant  in  China.  
Mineracao Curimbaba (“Curimbaba”), based in Brazil, also manufactures and markets ceramic proppant in competition with some of 
our products.  Imerys, S.A., a competitor based in France (“Imerys”), has ceramic proppant manufacturing facilities in Andersonville 
and Wrens, Georgia and also competes with some of our products.

We are aware of a number of manufacturers in China.  Most of these companies produce intermediate-density and low-density 
ceramic  proppants  that  are  marketed  both  inside  and  outside  of  China.    Chinese  proppant  imports  into  the  United  States  increased 
beginning  in  2010  and  2011,  which  contributed  to  an  over-supply  of  ceramic  proppant  beginning  in  2012.    However,  beginning  in 
early 2015, imports declined significantly or stopped.

Our KRYPTOSPHERE product line replaced both CARBOHSP and CARBOPROP.  Historically, competition for CARBOHSP 
and  CARBOPROP  principally  includes  ceramic  proppant  manufactured  by  Saint-Gobain,  Curimbaba,  as  well  as  various 
manufacturers located in China.  Our CARBOLITE, CARBOECONOPROP and CARBOHYDROPROP products compete primarily 
with  ceramic  proppant  produced  by  Saint-Gobain,  Curimbaba  and  Imerys  and  with  sand-based  proppant  for  use  in  the  hydraulic 
fracturing of natural gas and oil wells.  At this time, there is not in our view a comparable competitor’s product to our mono-mesh 
KRYPTOSPHERE product line, which is the subject of patent protection.

We  believe  that  some  of  the  significant  factors  that  influence  a  customer’s  decision  to  purchase  our  ceramic  proppant  are  (i) 
reservoir  and  geological  characteristics,  (ii)  price/performance  ratio,  (iii)  on-time  delivery  performance,  (iv)  technical  support,  (v) 
proppant availability and (vi) the financial status of E&P operators.  We believe that our products are competitively priced and that our 
delivery performance and customer experience is far better than the competition.  We have seen an increased usage of our technology 
proppants internationally and in North America, especially with E&Ps which are focused on increasing the EUR of their wells, are 
completing wells with higher permeability or are making attempts to lower their lease operating expenses (LOE).

The leading suppliers of Northern White mined sand are Covia Corporation, U.S. Silica Company, Hi-Crush Partners LP, and 
Badger Mining Corp. There are several other sand competitors (including the aforementioned) which have added in-basin capacity in 
the last year.  This is sand which has significantly lower quality (resulting in lower EUR and production), but is closer to where the 
wells will be completed resulting in significantly lower costs.  A large majority of our sand from our Northern White sand plant as 
well as the distribution center it is being railed into is under contract.

Our  industrial  ceramic  products  enhance  our  clients’  performance  for  their  manufacturing  processes,  products,  and  services.  
The two primary industries of the ten market segments we currently serve are foundry with our ACCUCAST products and grinding 
applications with our CARBOGRIND products.  Our industrial sector has competitors across several industries we sell into.

ACCUCAST metal casting media products are used by foundries to form high quality cores and molds.  During the past year, 
our  sales  activity  has  focused  on  North  America  and  primarily  in  the  United  States  due  to  the  new  OSHA  PEL  for  respirable 
crystalline  silica  that  went  into  effect  in  2018  for  foundries.    ACCUCAST  ceramic  media  is  a  solution  for  the  new  OSHA 
requirements.  We utilize direct sales B2B and a network of qualified distributors.  Our competition in the North American foundry 
market includes several ceramic media manufacturers and the primary competitors in the North American foundry market is Itochu 
and Prince Minerals.  Itochu, based in Tokyo and Osaka, Japan, is a diverse global company competing in many industries including 
Textile, Machinery, Metals & Minerals, Energy & Chemicals, Food, General Products & Realty, and Financial Business Services with 
distribution  facilities  and  manufacturing  located  globally.    Their  Cerabeads,  casting  media  for  the  foundry  market,  is  produced  in 
Japan  and  distributed  globally.    Sales  are  direct  B2B  and  through  a  broad  group  of  distributors.  Prince  Minerals,  headquarters  in 
Houston,  TX,  is  a  manufacturer  and  distributor  of  specialty  chemicals  and  industrial  additives.    They  sell  direct  B2B  and  through 
distributors selling both internally and externally manufactured products.  Their Ceramcast, media for the foundry market, has been 
historically produced by a third party manufacturer in China with narrow product offerings for foundries.

CARBOGRIND  products  are  used  in  milling  equipment  for  processing  ore  in  the  precious  metals  mining  industry  and  other 
milling applications such as pigments, paints, and ceramic tile.  Within the precious metals mining industry, we sell globally through 
direct sales teams and distributors.  Competitors in the precious metals mining industry include Keramos, Magotteaux, Saint Gobain, 
Kings, and Cenotec.  The majority of these competitors manufacture their ceramic grinding products in manufacturing plants located 
in China.     

We believe some of the significant factors that influence a customer’s decision to purchase our industrial ceramic media are (i) 
broad  portfolio  of  superior  ceramic  products  designed  specifically  to  solve  challenges  for  different  industries  (ii)  excellent 
price/performance  ratio,  (iii)  on-time  delivery  performance,  (iv)  technical  support,  (v)  product  availability  (vi)  consistent  superior 
quality  and  (vii)  the  financial  status  of  our  clients.    We  believe  our  industrial  products  are  competitively  priced  and  our  delivery 
performance and customer experience is better than the competition.  Lastly, our superior technical support has enabled us to persuade 
customers to use our products in an increasingly broad range of applications which in turn has increased the overall market for our 
industrial products.

The ASSETGUARD™ environmental sector is divided into two divisions: a manufacturing division and a services 
division.  The manufacturing division supplies products into both the oil and gas and industrial markets.  The service business, 
operating as Falcon Technologies, provides services to the oil and gas market.  In 2018, oil and gas activity levels accelerated beyond 
those seen in both 2016 as well as 2017, and as a result additional competition entered into the market.  Falcon Technologies operates 
in the United States, and we are aware of at least two dozen competitors operating within the United States.

It is our belief that there are several key factors that are driving customers to purchase from ASSETGUARD, including (i) 
centralized manufacturing, which offers customers one stop shopping capability, along with a proven track record of on time delivery 
and competitive pricing, (ii) field services that are established across the United States as being professional, efficient, and reliable and 
centered on customer satisfaction, (iii) and the technical support available to the customer is unmatched in the industry, ensuring that 
the client receives timely response to their issues and quick resolution to any problem that might arise.

Product Development

We  have  broadened  our  product  development  efforts  in  2018  to  address  the  dynamic  growth  of  the  industrial,  contract 
manufacturing,  and  environmental  sectors.    Product  development  efforts  are  roughly  equally  split  between  oilfield  and  industrial 
applications.   

SALTGUARD was commercialized in our GUARD® product line to prevent salt buildup in oil and gas wells.  

CARBOGRIND, our superior line of grinding media, portfolio of products continues to grow. Many new product offerings were 
launched in 2018 as a direct result of our customers requiring grinding solutions to solve their grinding challenges. The portfolio of 

4

 
products will continue to grow as our development team develops products with heavier densities, various sizes, and improve grinding 
performance. 

QUANTUM™  service  based  on  iON™  electrically  conducting  proppant  continues  to  be  the  industry  best  method  to  directly 

measure hydraulic fracture dimensions.  This technology will become commercial in 2019.   

Intellectual property continues to be a strong focus to support our technology leadership.  In 2018, ten patents were issued to the 

Company.  

Customers and Marketing

The customer base within CARBO is transforming as our revenue streams change from primarily oil and gas, to oil and gas, 
industrial and environmental customers.  The three business sectors are each utilizing different sales channels, including direct to the 
end consumer of our products and services, an intermediary which adds their services around our products, distributors and through 
ecommerce for certain products. We are seeing shifts in the purchasing behaviors of some of the end users of our products and have 
changed and are changing our sales and marketing efforts accordingly. 

Our largest customers are participants in the hydraulic fracturing industry.  Specifically, Halliburton Energy Services, Inc. and 
Keane Group which each accounted for more than 10% of our 2018 revenues.    We generally supply our customers with products on 
a just-in-time basis, as specified in individual purchase orders.  Continuing sales of product depend on our direct customers and the 
operators  being  satisfied  with  value  creation,  product  quality,  availability  and  delivery  performance.    In  addition,  our  ability  to 
increase sales of our products and services depends on a favorable level of activity in the upstream oil and gas industry and expansion 
into other industrial and environmental business segments as well as capturing further market share in conventional segments.

We recognize the importance of a technical marketing program in demonstrating long-term economic advantages when selling 
products and services that offer financial benefits over time.  We have a broad technical sales force to advise end users on the benefits 
of  using  our  base  ceramic  proppant,  technology  ceramic  products,  fracture  simulation  software,  and  related  consulting  services.  In 
addition  we  have  added  domain  technical  expertise  within  our  industrial  business  unit  to  provide  technical  recommendations  and 
ongoing support throughout the sales and ownership process. We also believe that our new product introductions and education-based 
technical  marketing  efforts  have  enabled  us  to  maintain  our  position  not  only  as  one  of  the  world’s  largest  suppliers  of  ceramic 
proppant but also as a leading innovator in the three sectors we sell into: oil and gas, industrial and environmental.

Our  international  marketing  efforts  are  conducted  primarily  through  our  sales  offices  in  Houston,  the  United  Arab  Emirates, 
Canada, Europe, and South America.  Our products and services are used worldwide by U.S. customers operating domestically and 
abroad,  and  by  foreign  customers.    Sales  outside  the  United  States  accounted  for  19%  and  21%  of  our  sales  for  2018  and  2017, 
respectively.    The  distribution  of  our  international  and  domestic  revenues  is  shown  below,  based  upon  the  region  in  which  the 
customer used the products and services:

Production Capacity

We  have  adequate  capacity  to  support  present  and  foreseeable  demand  for  our  products.  We  continue  to  incorporate  new 
methods and technologies to reduce our manufacturing costs and make our products more cost-competitive.   Our manufacturing costs 
per  unit  are  typically  inversely  related  to  production  levels.    When  production  levels  increase,  costs  per  unit  tend  to  decrease,  and 
when production levels decrease, costs per unit tend to increase.

Stated capacity of our facilities varies based on the mix of products we expect to produce.  The following table sets forth the 

current stated capacity of each of our existing ceramic manufacturing and other facilities:

Given market conditions, output levels at these facilities are at reduced levels.
Processing  activities  at  the  New  Iberia  facility  primarily  involve  resin-coating  of  previously  manufactured  ceramic  proppant 
substrate.

The retrofit of the first production line at our Eufaula, Alabama plant to produce KRYPTOSPHERE was completed in late 2015.  
With this retrofit, we can now produce up to approximately 100 million pounds of KRYPTOSPHERE annually.  While this retrofit 
enables production of our new KRYPTOSPHERE technology products, it did not add additional production capacity.

During  2018,  our  overall  total  ceramic  plant  utilization,  excluding  our  Millen  plant,  which  we  sold  in  December  2018,  was 
approximately 16% of stated capacity.  Our sand processing plant in Marshfield operated at approximately 73% of its stated capacity 
during 2018.  We expect improvements to our plant utilization in 2019 due to contract manufacturing growth.  We expect utilization at 
our sand processing plant to improve during 2019.  Depending on industry conditions, we can modify output levels or idle operations 
at plants as needed.  Refer to our discussion of impairment considerations in the “Critical Accounting Policies” section of Item 7 - 
Management’s Discussion and Analysis of Financial Condition and Results of Operations.  Construction of additional manufacturing 
capacity  beyond  our  existing  facilities  is  not  expected  in  the  foreseeable  future,  and  would  be  dependent  on  the  expected  future 
demand for our products, access to needed capital and the ability to obtain necessary environmental permits.

Distribution

We  maintain  finished  goods  inventories  at  each  of  our  manufacturing  facilities  and  at  remote  stocking  facilities.    Our  North 
American remote stocking facilities consist of bulk storage silos with truck trailer and sand box loading facilities, as well as rail yards 
for  direct  transloading  from  rail  cars  to  truck  trailers.    International  remote  stocking  sites  are  duty-free  warehouses  operated  by 
independent owners.  North American sites are typically supplied by rail, and international sites are typically supplied by container 
ship.    In  total,  we  lease  approximately  1,691  rail  cars  for  use  in  the  distribution  of  our  products,  of  which  we  have  subleased 
approximately 570 rail cars.

Raw Materials 

Ceramic proppant and ceramic media are made from alumina-bearing ores (commonly referred to as clay, bauxite, bauxitic clay 
or kaolin, depending on the alumina content) that are readily available on the world market.  The main known deposits of alumina-
bearing ores in the United States are in Arkansas, Alabama and Georgia; other economically mineable known deposits are located in 
Australia, Brazil, China, Gabon, Guyana, India, Jamaica, Russia and Surinam.  Bauxite is largely used in the production of aluminum 
metal, refractory material and abrasives.  We believe that our ability to purchase bauxite on the open market coupled with our current 
bauxite inventories will sufficiently provide for our bauxite needs in the United States during 2019.

Our  Eufaula,  McIntyre  and  Toomsboro  facilities  primarily  use  locally  mined  kaolin  for  the  production  of  CARBOLITE, 
CARBOECONOPROP and CARBOHYDROPROP.  We have entered into bi-lateral contracts that require a supplier to sell to us, and 
require us to purchase from the supplier, at least fifty percent of the Eufaula facility’s annual kaolin requirements.  The contract runs 
through May 2020, with an option for us to extend this agreement for additional three year terms.  We have obtained ownership rights 
in acreage in Wilkinson County, Georgia, which contains in excess of a twelve year supply of kaolin for our Georgia facilities based 
on full capacity production rates.  We have entered into a long-term agreement with a third party to mine and transport this material at 
a fixed price subject to annual adjustment.  The agreement requires us to utilize the third party to mine and transport a majority of the 
McIntyre and Toomsboro facility’s annual kaolin requirement.  Overall, we estimate that our fee simple and leasehold mineral rights 

6

 
 
 
  
 
  
 
in the states of Alabama and Georgia contain approximately 19.0 million tons of kaolin suitable for use in production of our kaolin-
based proppants.

We utilize our own Northern White sand, CARBO NORTHERN-WHITE, and purchase third party wet processed sand reserves 

for our sand processing facility in Marshfield, Wisconsin, which supplies raw frac sand to the proppant market.

Ceramic Production Process

Ceramic proppants are made by grinding or dispersing ore to a fine powder, combining the powder into small pellets and firing 
the pellets in a rotary kiln.  We use three different methods to produce ceramic proppant.  Industrial ceramic media follows a similar 
process.

Our  plant  in  McIntyre,  Georgia  uses  a  dry  process,  which  utilizes  clay,  bauxite,  bauxitic  clay  or  kaolin.    The  raw  material  is 

ground, pelletized and screened.  The manufacturing process is completed by firing the product in a rotary kiln.

Our plants in Eufaula, Alabama and Toomsboro, Georgia use a wet process, which starts with kaolin that is formed into slurry.  

The slurry is then pelletized in a dryer and the pellets are then fired in a rotary kiln.

The  portion  of  our  plant  in  New  Iberia,  Louisiana  that  manufactures  ceramic  proppant,  as  well  as  one  line  at  our  Eufaula, 

Alabama facility, uses a proprietary manufacturing process associated with the Company’s KRYPTOSPHERE product line.  

Our rotary kilns are primarily heated by the use of natural gas.

Patent Protection and Intellectual Property

We make ceramic proppant and ceramic media used in foundry, grinding and scouring processes by processes and techniques 

that involve a high degree of proprietary technology, some of which is protected by patents.

We own multiple patents in the United States and various foreign countries that relate to different types of ceramic proppant and 
production methods used for ceramic proppant and ceramic media; however, depending on market conditions, production of products 
pursuant  to  these  patents  may  not  necessarily  constitute  a  material  portion  of  our  output.   We  also  own  multiple  U.S.  and  foreign 
patents  that  relate  to  methods  for  the  detection  of  subterranean  fractures  and  material,  including  gravel  packs,  in  the  near-borehole 
region.  We also own multiple U.S. patents that relate to detectable proppant.

During 2014 and 2015, we obtained three U.S. patents relating to our KRYPTOSPHERE manufacturing process, during 2017, 
we obtained one U.S. patent covering the KRYPTOSPHERE product, and during 2018, we obtained another U.S. patent covering the 
KRYPTOSPHERE product, each of which expire in 2031, and another U.S. patent relating to our KRYPTOSPHERE manufacturing 
process, which expires in 2036.  Also, during 2018, we obtained two U.S. patents relating to our GUARD product lines, which expire 
in  2035  and  one  U.S.  patent  relating  to  our  FUSION  product  line,  which  expires  in  2037.   We  expect  these  patents  to  provide 
assistance in the future sales of these product lines.  During 2015, 2016, 2017, and 2018, we obtained six U.S. patents, which expire in 
2033,  2034,  2035  and  2036  and  relate  to  our  far-field  proppant  detection  products,  systems  and  methods  which  relate  to  our  iON 
product line and the QUANTUM service line, which are still under development.   

We  own  multiple  U.S.  patent  applications  (together  with  a  number  of  counterpart  applications  pending  in  foreign 
jurisdictions).  A portion of the U.S. patent applications cover ceramic proppant, detectable proppant, processes for making ceramic 
proppant and detectable proppant, tracers for detecting produced fluids, diversion particles, detection of subterranean fractures, and 
our KRYPTOSPHERE, GUARD, FUSION, CARBOAIR, and NANOMITE product lines and methods for making and using these 
products.   Another  portion  of  the  U.S.  patent  applications  cover  non-oilfield  or  industrial  products,  such  as  water  treatment 
compositions,  foundry  media,  building  materials  and  ceramic  media  for  use  in  solar  power  plants.   The  applications  are  in  various 
stages of the patent prosecution process, and patents may not issue on such applications in any jurisdiction for some time, if they issue 
at all.

AGPI  owns  three  U.S.  patents,  which  expire  in  2026,  2027  and  2034  and  relate  to  construction  of  secondary  containment 
areas.   In  addition,  AGPI  owns  four  U.S.  patents,  which  expire  in  2030  and  2031  and  relate  to  polyurea-encapsulated  tank 
bases.  AGPI also owns multiple U.S. patent applications, each of which relates to tank bases, equipment bases, portable containments, 
or components useful in containment areas in upstream, midstream and downstream environments.

We believe that our patents have historically been important in enabling us to compete in the market to supply proppant to the 
natural gas and oil industry.  We intend to enforce, and have in the past vigorously enforced, our patents.  We may from time to time 
be  involved  in  litigation  to  determine  the  enforceability,  scope  and  validity  of  our  patent  rights.   In  addition  to  patent  rights,  and 
perhaps more notably, we use a significant amount of trade secrets, or “know-how,” and other proprietary information and technology 
in the conduct of our business.  None of this “know-how” and technology is licensed from third parties.  However, we have negotiated 
a long term license for some third party intellectual property used or jointly developed in connection with our QUANTUM service 
line.

Seasonality

Historically, we have experienced higher levels of proppant and environmental sales activities during warmer weather periods 
and less during colder weather months in the northern and eastern United States.  In addition, sales activities can be decreased by the 
spring  snow  and  ice  “break-up”  in  Canada,  North  Dakota,  Montana,  and  the  Northeast  U.S.,  as  well  as  the  winter  holidays  in 
December and January.  Our industrial ceramic media products are not typically impacted by seasonality.

Environmental and Other Governmental Regulations

We  believe  that  our  operations  are  in  substantial  compliance  with  applicable  domestic  and  foreign  federal,  state  and  local 

environmental and safety laws and regulations.

Existing federal environmental requirements such as the Clean Air Act and the Clean Water Act, as amended, impose certain 
restrictions on discharge of air and water pollutants from our operations via permits and regulations.  Those pollutants include volatile 
organic  compounds,  nitrogen  oxides,  sulfur  dioxide,  particulate  matter,  storm  water  and  wastewater  discharges  and  other  by-
products.  In addition to meeting environmental requirements for existing operations, the Company must also demonstrate compliance 
with  environmental  regulations  in  order  to  obtain  any  required  permits  prior  to  any  future  expansion.   The  United  States 
Environmental Protection Agency (“EPA”) and state programs require covered facilities to obtain individual permits or have coverage 
under an EPA general permit issued to groups of facilities.  A number of federal and state agencies, including but not limited to, the 
EPA,  the  Texas  Commission  on  Environmental  Quality,  the  Louisiana  Department  of  Environmental  Quality,  the  Alabama 
Department  of  Environmental  Management,  the  Wisconsin  Department  of  Natural  Resources,  and  the  Environmental  Protection 
Division  of  the  Georgia  Department  of  Natural  Resources  promulgate  and  enforce  environmental  regulations  applicable  to  our 
operations  in  the  states  in  which  we  do  business.   Historically  we  have  been  able  to  obtain  permits,  where  necessary,  to  build new 
facilities and modify existing facilities that allow us to continue compliant operations.  Obtaining these permits in a timely manner 
will continue to be an important factor in our ability to do so in the future.

Employees

As  of  December  31,  2018,  we  had  407  employees  worldwide.    In  addition  to  the  services  of  our  employees,  we  employ  the 
services of consultants as required.  Our employees are not represented by labor unions.  There have been no work stoppages or strikes 
during  the  last  three  years  that  have  resulted  in  the  loss  of  production  or  production  delays.    We  believe  our  relations  with  our 
employees are satisfactory.

Item 1A. Risk Factors

You should consider carefully the trends, risks and uncertainties described below and other information in this Form 10-K and 
subsequent reports filed with the SEC before making any investment decision with respect to our securities.  If any of the following 
trends,  risks  or  uncertainties  actually  occurs  or  continues,  our  business,  financial  condition  or  operating  results  could  be  materially 
adversely affected, the trading prices of our securities could decline and you could lose all or part of your investment.

Our business and financial performance largely depends on the level of activity in the natural gas and oil industries.

Our  operations  are  materially  dependent  upon  the  levels  of  activity  in  natural  gas  and  oil  exploration,  development  and 
production.  More specifically, the demand for our products is related to the number of natural gas and oil wells completed in geologic 
formations where ceramic or sand proppants are used in fracture treatments.  These activity levels are affected by both short-term and 
long-term  trends  in  oil  and  natural  gas  prices.    In  recent  years,  oil  and  natural  gas  prices  and,  therefore,  the  level  of  exploration, 
development and production activity, have experienced significant fluctuations.  Worldwide economic, political and military events, 
including  war,  terrorist  activity,  events  in  the  Middle  East  and  initiatives  by  OPEC,  have  contributed,  and  are  likely  to  continue  to 
contribute, to price volatility.  Despite recent initiatives to curb supply, the global supply of oil is currently at historically high levels, 
and there is potential for geopolitical and regulatory events, such as normalization of trade relations with the Islamic Republic of Iran, 
to  further  increase  the  supply  of  oil.    Additionally,  warmer  than  normal  winters  in  North  America  and  other  weather  patterns  may 
adversely  impact  the  short-term  demand  for  natural  gas  and,  therefore,  demand  for  our  products  and  services.    Natural  gas  prices 
experienced a significant decline during 2012 and, although they have increased since then, remain relatively low on a historic basis, 
resulting in generally lower gas drilling activity.  Further, the price of oil declined precipitously from the second half of 2014 through 
mid-2016  and,  although  the  price  rebounded  from  its  low  in  the  first  half  of  2018,  it  decreased  again  in  the  second  half  and  still 
remains at weakened levels.  This reduction in oil and natural gas prices has depressed the level of natural gas and oil exploration, 
development,  production  and  well  completions  activity,  resulting  in  significantly  reduced  demand  and  pricing  for  our  base  ceramic 
and sand products.  In addition and because of the depressed commodity prices, we have seen a significant increase in the use of very 
low quality in-basin sand at the expense of lower production for unconventional wells, which have extremely low quality reservoirs. 
This  decline  has  had,  and  continues  to  have,  a  significant  adverse  impact  on  our  results.    If  oil  and  natural  gas  prices  and  well 
completion  activity  do  not  materially  improve  and/or  demand  for  our  products  does  not  otherwise  increase,  this  decline  could 
reasonably be expected to have a material adverse effect on our financial condition or operations, including, but not limited to, the 
temporary idling of all, or a portion of all, of our facilities utilized for this sector of our business until such time as market conditions 
improve.

10

We  may  not  have  sufficient  cash  and/or  be  able  to  access  liquidity  alternatives  in  the  credit  and  capital  markets  to  meet  our 
liquidity needs.

Our primary sources of liquidity are cash on hand and cash flow from operations.  Our ability to fund our working capital and 
capital expenditures and other obligations depends on our future operating performance and cash from operations and other liquidity-
generating transactions, which are in turn subject to prevailing oil and natural gas prices, economic conditions and other factors, many 
of which are beyond our control.  

If  our  future  operating  performance  falls  materially  below  our  expectations,  our  plans  prove  to  be  materially  inaccurate,  or 
industry  conditions  do  not  materially  improve,  we  may  require  additional  financing.    Even  if  additional  or  alternative  financing 
becomes available to us, future financing transactions may significantly increase the Company’s interest expense, which could in turn 
reduce  our  financial  flexibility  and  our  ability  to  fund  other  activities,  and  could  make  us  more  vulnerable  to  changes  in  operating 
performance or economic downturns generally.  The inability to generate sufficient cash, modify our New Credit Agreement, or obtain 
replacement or additional financing, or an event of default under our New Credit Agreement, could have a material adverse effect on 
our financial condition.

We therefore cannot provide any assurance that we will be able to access the capital or credit markets on acceptable terms or 
timing, or at all.  Access to the capital markets and the cost and availability of credit may be adversely affected by factors beyond our 
control, including turmoil in the financial services industry, volatility in securities trading markets, the continuing downturn in the oil 
and gas industry and general economic conditions.  Currently, we do not qualify as a “well-known seasoned issuer,” which otherwise 
would allow us to, among other things, file automatically effective shelf registration statements.  Now, even if we are able to access 
the  public  capital  markets,  any  attempt  to  do  so  could  be  more  expensive  or  subject  us  to  significant  delays  when  compared  with 
previous periods.

Our  business  and  financial  performance  has  suffered  and  could  suffer  further  if  the  levels  of  hydraulic  fracturing  continue  to 
decline or cease as a result of the low commodity price of oil and natural gas, development of new processes, increased regulation 
or a continued decrease in drilling activity.

A large portion of our products are proppants used in the completion and re-completion of natural gas and oil wells through the 
process of hydraulic fracturing.  Completion activity is directly impacted by the price of oil and natural gas.  In addition, demand for 
our proppants is substantially higher in the case of horizontally drilled wells, which allow for multiple hydraulic fractures within the 
same well bore but are more expensive to develop than vertically drilled wells.  A reduction in horizontal drilling or the development 
of new processes for the completion of natural gas and oil wells leading to a reduction in, or discontinuation of the use of, hydraulic 
fracturing  could  cause  a  decline  in  demand  for  our  products.    Additionally,  increased  regulation  or  environmental  restrictions  on 
hydraulic fracturing or the materials used in this process could negatively affect our business by increasing the costs of compliance or 
resulting in operational delays, which could cause operators to abandon the process due to commercial impracticability.  Moreover, 
future federal, state, local or foreign laws or regulations could otherwise limit or ban hydraulic fracturing.  Several states in which our 
customers  operate  have  adopted,  or  are  considering  adopting,  regulations  that  have  imposed,  or  could  impose,  more  stringent 
permitting, transparency, disposal and well construction requirements on hydraulic fracturing operations.  Some states, such as New 
York, have banned the process of hydraulic fracturing altogether.  Any of these events could have a material adverse effect on our 
results of operations and financial condition.  As stated elsewhere, the upstream oil and natural gas industry is in the midst of a severe 
contraction,  resulting  in  a  significant  reduction  in  horizontal  drilling  and  further  resulting  in  a  material  decline  in  demand  for  our 
products and services.

We face distribution and logistical challenges in our business.

As  oil  and  natural  gas  prices  fluctuate,  our  customers  may  shift  their  focus  back  and  forth  between  different  resource  plays, 
some  of  which  can  be  located  in  geographic  areas  that  do  not  have  well-developed  transportation  and  distribution  infrastructure 
systems.    Transportation  and  logistical  operating  expenses  continue  to  comprise  a  significant  portion  of  our  total  delivered  cost  of 
sales.  Therefore, serving our clients in these less-developed areas presents distribution and other operational challenges that affect our 
sales and negatively impact our operating costs.  Disruptions in transportation services, including shortages of rail cars or a lack of rail 
transportation  services  or  developed  infrastructure,  could  affect  our  ability  to  timely  and  cost  effectively  deliver  products  to  our 
customers and could provide a competitive advantage to competitors located in closer proximity to customers.  Additionally, increases 
in  the  price  of  diesel  fuel  could  negatively  impact  operating  costs  if  we  are  unable  to  pass  those  increased  costs  along  to  our 
customers.  Failure to find long-term solutions to these logistical challenges could adversely affect our ability to respond quickly to the 
needs of our customers or result in additional increased costs, and thus could negatively impact our results of operations and financial 
condition. 

11

We operate in an increasingly competitive market.

The proppant market is highly competitive.  We compete with other domestic and international suppliers of ceramic proppant, as 
well  as  with  suppliers  of  sand  for  use  as  proppant,  in  the  hydraulic  fracturing  of  natural  gas  and  oil  wells.    The  expiration  of  key 
patents owned by the Company has resulted in additional competition in the market for ceramic proppant.  The entry of additional 
competitors into the market, and/or a surge in the level of ceramic proppant imports into North America from existing competitors, 
could have a material adverse effect on our results of operations and financial condition.

Our industrial products have competitors across several industries we sell into.  Competition for products in the North American 
foundry market includes several ceramic media manufacturers.  There are also a number of competitors in the grinding market that 
primarily manufacture their ceramic grinding products in China.  We believe our industrial products are competitively priced, are of 
higher quality and our customer experience is better than the competition.

Our environmental products have a large number of competitors across the United States.  There are few barriers to entry in this 
market, however we do own key patents for some of our environmental products.  We believe there are several key factors that drive 
customers  to  purchase  our  environmental  products  over  the  competition  including  centralized  manufacturing,  on  time  delivery, 
competitive pricing, a focus on customer satisfaction, and excellent technical support.  

Adverse  changes  to  these  key  factors  or  a  shift  in  customer  preferences  to  our  competitor's  products  could  have  a  material 

adverse effect on our results of operations and financial condition.

We  have  been  and  may  continue  to  be  adversely  affected  by  decreased  demand  for  our  proppant  or  the  development  by  our 
competitors of alternative proppants.

Ceramic proppant is a premium product capable of withstanding higher pressure and providing more highly conductive fractures 
than mined sand, which is the most commonly used proppant type.  We continue to see operators that have traditionally used ceramic 
proppant  shifting  to  use  mined  sand  instead.    Despite  recently  improving  commodity  prices  in  the  oil  and  natural  gas  industry, 
continued pressure on operators to reduce cost or to evaluate returns on a shorter horizon has had a detrimental impact on the demand 
for ceramic proppant, which is a higher cost product than mined sand.  Although we believe that the use of quality ceramic proppant in 
appropriate geologic formations typically generates higher production rates and more favorable long-term production economics than 
mined sand, the shifting of customer demand to lower cost products, such as mined sand, has had an adverse effect on our results of 
operations  and  its  continuation  could  have  a  material  adverse  effect  on  our  financial  condition.    The  development  and  use  of 
alternative proppant could also cause a decline in demand for our products, and could have a material adverse effect on our results of 
operations and financial condition.

We  have  no  current  plans  to  pay  cash  dividends  on  our  common  stock  for  the  foreseeable  future  and  our  Amended  Credit 
Agreement contains restrictions on our ability to pay dividends; therefore, you may not receive any return on investment unless 
you sell your common stock for a price greater than you paid.

We do not plan to declare dividends on shares of our common stock in the foreseeable future.  In addition, our Amended Credit 
Agreement prohibits us from paying such dividends.  We currently intend to retain any future earnings to finance the operation of our 
business and meet our debt obligations.  As a result, you may only receive a return on your investment in our common stock if the 
market price of our common stock increases.  Further, one of our financing options involves the issuance of equity securities, which 
would dilute current stockholders and could reduce our stock price.

The  outstanding  indebtedness  under  our  New  Credit  Agreement  is  secured  by  a  substantial  portion  of  our  domestic  assets  and 
guaranteed by our two domestic operating subsidiaries, subject to certain exceptions.

The  outstanding  indebtedness  under  our  New  Credit  Agreement  is  secured  by  (i)  a  pledge  of  all  accounts  receivable  and 
inventory,  (ii)  cash  in  certain  accounts,  (iii)  domestic  distribution  assets  residing  on  owned  real  property,  (iv)  our  Marshfield, 
Wisconsin and Toomsboro, Georgia plant facilities and equipment, and (v) certain real property interests in mines and minerals.  In 
the event of a default, our lenders may (1) elect to declare all outstanding borrowings made under the New Credit Agreement and the 
guaranties  of  the  two  operating  subsidiaries,  together  with  accrued  interest  and  other  fees,  to  be  immediately  due  and  payable;  (2) 
exercise their set-off rights; and/or (3) enforce and foreclose on their security interest and liquidate some or all of such pledged assets.  
Any of these actions could, individually or in the aggregate, have a substantial negative impact on our financial condition and results 
of operations.

12

We rely upon, and receive a significant percentage of our revenues from, a limited number of key customers and end users.

During  2018,  our  key  customers  included  several  of  the  largest  participants  in  the  worldwide  petroleum  pressure  pumping 
industry.  Two of these customers each accounted for more than 10% of our 2018 revenues.  However, the end users of our products 
are  numerous  operators  of  natural  gas  and  oil  wells  that  hire  pressure  pumping  service  companies  to  hydraulically  fracture 
wells.   During  2018,  a  majority  of  our  ceramic  proppant  sales  were  directed  to  a  concentrated  number  of  end  users.   We  generally 
supply  our  domestic  pumping  service  customers  with  products  on  a  just-in-time  basis,  with  transactions  governed  by  individual 
purchase  orders  and/or  a  master  supply  agreement.   Because  of  their  purchasing  power,  our  key  customers  may  have  greater 
bargaining leverage than us with respect to the negotiation of prices and other terms of the sale in their supply contracts with us, which 
in turn, could adversely affect our profit margins associated with those contracts.  Disparities in bargaining leverage, when combined 
with the Company’s desire to maintain long-term relationships with key customers, could limit our practical ability to assert certain 
terms of our supply agreements with them.  Continuing sales of our products depend on our direct customers and the end user well 
operators being satisfied with product quality, pricing, availability, and delivery performance.  While we believe we have satisfactory 
relations with our customers and our end users, a material decline in the level of sales to any one of our major customers or loss of a 
key end user due to unsatisfactory product performance, pricing, delivery delays or any other reason could have a material adverse 
effect on our results of operations and financial condition.

The operations of our customers, and thus the results of our operations, are subject to a number of operational risks, interruptions 
and seasonal trends.

As hydraulic fracturing jobs have increased in size and intensity, common issues such as weather, equipment delays or changes 
in  the  location  and  types  of  oil  and  natural  gas  plays  can  result  in  increased  variability  in  proppant  sales  volumes.    Our  business 
operations  and  those  of  our  customers  involve  a  high  degree  of  operational  risk.    Natural  disasters,  adverse  weather  conditions, 
collisions and operator error could cause personal injury or loss of life, severe damage to and destruction of property, equipment and 
the environment, and suspension of operations.  Our customers perform work that is subject to unexpected or arbitrary interruption or 
termination.  The occurrence of any of these events could result in work stoppage, loss of revenue, casualty loss, increased costs and 
significant  liability  to  third  parties.    With  the  increase  in  resource  plays  in  the  northern  and  eastern  United  States,  as  well  as  our 
operations in Marshfield, Wisconsin, our results of operations are increasingly exposed to seasonal variations and inclement weather.  
Operations in certain regions involve more seasonal risk in the winter months, and work is hindered during other inclement weather 
events.  This variability makes it more difficult to predict sales and can result in greater fluctuations to our quarterly financial results.  
These quarterly fluctuations could result in operating results that are below the expectations of public market analysts and investors, 
and therefore may adversely affect the market price for our common stock.

The ability of our customers to complete work, as well as our ability to mine sand from cold climate areas, could be affected 
during  the  winter  months.    Our  revenue  and  profitability  could  decrease  during  these  periods,  as  well  as  in  other  severe  weather 
conditions, because work is either prevented or more costly to complete.  If a substantial amount of production is interrupted, our cash 
flow and, in turn, our results of operations could be materially and adversely affected.

Our  North  American  ceramic  proppant  production  is  manufactured  at  two  plants.    The  vast  majority  of  our  mined  sand  is 
processed at one plant.  Any adverse developments at those plants could have a material adverse effect on our financial condition 
and results of operations.

With  the  very  limited  production  at  our  McIntyre  plant,  we  are  producing  the  majority  of  our  North  American  ceramic 
production from two plants, our Eufaula and our Toomsboro plant.  Our Marshfield, Wisconsin plant represents the vast majority of 
our annual mined sand processing capacity.  Any adverse developments at these plants, including a material disruption in production, 
an inability to supply the plant with raw materials at a competitive cost, or adverse developments due to catastrophic events, could 
have a material adverse effect on our financial condition and results of operations.

We provide environmental warranties on certain of our containment and spill prevention products.

AGPI’s  tank  liners,  secondary  containments  and  related  products  and  services  are  designed  to  contain  or  avoid  spills  of 
hydrocarbons and other materials.  If a release of these materials occurs, it could be harmful to the environment.  Although we attempt 
to  negotiate  appropriate  limitations  of  liability  in  the  applicable  terms  of  sale,  some  customers  have  required  expanded  warranties, 
indemnifications or other terms that could hold AGPI responsible in the event of a spill or release under particular circumstances.  If 
AGPI is held responsible for a spill or release of materials from one of its customer’s facilities, it could have a material adverse effect 
on our results of operations and financial condition.

13

We rely upon intellectual property to protect our proprietary rights.  Failure to protect our intellectual property rights may affect 
our competitive position, and protecting our rights or defending against third-party allegations of infringement may be costly.

The Company uses a significant amount of trade secrets, or “know-how,” and other proprietary information and technology in 
the  conduct  of  its  business.    In  some  cases,  we  rely  on  trade  secrets,  trademarks  or  contractual  restrictions  to  protect  intellectual 
property  rights  that  are  not  patented.    The  steps  we  take  to  protect  the  non-patented  intellectual  property  may  not  be  sufficient  to 
protect  it  and  any  loss  or  diminishment  of  such  intellectual  property  rights  could  negatively  impact  our  competitive  advantage.  
Additionally, our competitors could independently develop the same or similar technologies that are only protected by trade secret and 
thus do not prevent third parties from competing with us.  Furthermore, even protected intellectual property rights can be infringed 
upon by third parties.  Monitoring unauthorized use of Company intellectual property can be difficult and expensive, and adequate 
remedies may not be available.

Although  the  Company  does  not  believe  that  it  is  infringing  upon  the  intellectual  property  rights  of  others  by  using  such 
proprietary information and technology, it is possible that such a claim might be asserted against the Company in the future.  In the 
event any third party makes a claim against us for infringement of patents or other intellectual property rights of a third party, such 
claims, with or without merit, could be time-consuming and result in costly litigation.  In addition, the Company could experience loss 
or cancellation of customer orders, experience product shipment delays, or be subject to significant liabilities to third parties.  If our 
products or services were found to infringe on a third party’s proprietary rights, the Company could be required to enter into royalty or 
licensing agreements to continue selling its products or services.  Royalty or licensing agreements, if required, may not be available on 
acceptable terms, if at all, which could seriously harm our business.  Involvement in any patent dispute or other intellectual property 
dispute or action to protect trade secrets and expertise could have a material adverse effect on the Company’s business.

Significant increases in fuel prices for any extended periods of time will increase our operating expenses.

The  price  and  supply  of  natural  gas  are  unpredictable,  and  can  fluctuate  significantly  based  on  international,  political  and 
economic  circumstances,  as  well  as  other  events  outside  of  our  control,  such  as  changes  in  supply  and  demand  due  to  weather 
conditions, actions by OPEC and other oil and gas producers, regional production patterns and environmental concerns.  Natural gas is 
a significant component of our direct manufacturing costs and price escalations will likely increase our operating expenses and can 
have a negative impact on income from operations and cash flows.  We operate in a competitive marketplace and may not be able to 
pass through all of the increased costs that could result from an increase in the cost of natural gas.

Environmental compliance costs and liabilities could reduce our earnings and cash available for operations.

We  are  subject  to  increasingly  stringent  laws  and  regulations  relating  to  environmental  protection,  including  laws  and 
regulations governing air emissions, water discharges and waste management.  The technical requirements of complying with these 
environmental  laws  and  regulations  are  becoming  increasingly  expensive  and  complex,  and  may  affect  the  Company’s  ability  to 
expand its operations.  Our ability to continue the expansion of our manufacturing capacity to meet market demand is contingent upon 
obtaining required environmental permits and compliance with their terms, which continue to be more restrictive and require longer 
lead times to obtain in anticipation of any efforts to expand and increase capacity.  We incur, and expect to continue to incur, capital 
and operating costs to comply with environmental laws and regulations.

In addition, we use some hazardous substances and generate certain industrial wastes in our operations.  Many of our current 
and former properties are, or have been, used for industrial purposes.  Accordingly, we could become subject to potentially material 
liabilities  relating  to  the  investigation  and  cleanup  of  contaminated  properties,  and  to  claims  alleging  personal  injury  or  property 
damage  as  the  result  of  exposures  to,  or  releases  of,  hazardous  substances.    These  laws  also  may  provide  for  “strict  liability”  for 
damages to natural resources or threats to public health and safety.  Strict liability can render a party liable for environmental damage 
without regard to negligence or fault on the part of the party.  Some environmental laws provide for joint and several strict liability for 
remediation of spills and releases of hazardous substances.

Stricter  enforcement  of  existing  laws  and  regulations,  new  laws  and  regulations,  the  discovery  of  previously  unknown 
contamination  or  the  imposition  of  new  or  increased  requirements  could  restrict  our  expansion  efforts,  require  us  to  incur  costs,  or 
become the basis of new or increased liabilities.  Any of these events could reduce our earnings and our cash available for operations.

14

Our international operations subject us to risks inherent in doing business on an international level that could adversely impact 
our results of operations.

International  revenues  accounted  for  approximately  19%  and  21%  of  our  total  revenues  in  2018  and  2017,  respectively.    We 
may  not  succeed  in  overcoming  the  risks  that  relate  to  or  arise  from  operating  in  international  markets.    Risks  inherent  in  doing 
business on an international level include, among others, the following:

taxation of our earnings and the earnings of our personnel;

potential expropriation of assets by foreign governments and

other risks relating to the administration of or changes in, or new interpretations of, the laws, regulations and policies of 
the jurisdictions in which we conduct our business.

Undetected defects in our fracture simulation software could adversely affect our business.

Despite extensive testing, our software could contain defects, bugs or performance problems.  If any of these problems are not 
detected, the Company could be required to incur extensive development costs or costs related to product recalls or replacements.  The 
existence of any defects, errors or failures in our software products may subject us to liability for damages, delay the development or 
release of new products and adversely affect market acceptance or perception of our software products or related services, any one of 
which could materially and adversely affect the Company’s business, results of operations and financial condition.

The market price of our common stock will fluctuate, and could fluctuate significantly.

The market price of the Company’s common stock will fluctuate, and could fluctuate significantly, in response to various factors

Our actual results could differ materially from results anticipated in forward-looking statements we make.

Some  of  the  statements  included  or  incorporated  by  reference  in  this  Form  10-K  are  forward-looking  statements.    These 
forward-looking statements include statements relating to trends in the natural gas and oil industries, the demand for ceramic proppant 
and our performance in the "Management's Discussion and Analysis of Financial Condition and Results of Operations" and "Business" 
sections of this Form 10-K.  In addition, we have made and may continue to make forward-looking statements in other filings with the 
SEC, and in written material, press releases and oral statements issued by us or on our behalf.  Forward-looking statements include 
statements regarding the intent, belief or current expectations of the Company or its officers.  Our actual results could differ materially 

15

from  those  anticipated  in  these  forward-looking  statements,  and  our  financial  forecasts  are  particularly  sensitive  to  changes  in  the 
current  market  conditions.    Further,  our  financial  forecasts  have  been  less  accurate  during  the  recent  downturn.    See  "Business–
Forward-Looking Information."

The success of our business depends on achieving our strategic objectives, including the diversification of our product and service 
portfolio.

As we continue to expand our portfolio of product and service offerings to industrial and other new markets, we face certain 
risks  associated  with  these  new  business  strategies,  including  unknown  regulatory  changes  and  product  acceptance  by  these  new 
markets,  that  could  affect  our  future  financial  results.    In  addition,  lower  than  expected  sales  in  these  new  markets  could  have  a 
material adverse effect on our results from operations and financial condition.

We maintain our corporate headquarters in leased office space in Houston, Texas and also lease space for our technology center 
in  Houston.    We  own  our  manufacturing  facilities,  land  and  substantially  all  of  the  related  production  equipment  in  New  Iberia, 
Louisiana, and Eufaula, Alabama, and lease our McIntyre and Toomsboro, Georgia, facilities.  We own the buildings and production 
equipment at our facility in Luoyang, China, and have been granted use of the land on which the facility is located through 2051 under 
the terms of a land use agreement with the People’s Republic of China.  The Luoyang, China facility was shut down during 2015, and 
we do not intend to resume production.

The  facilities  in  McIntyre  and  Toomsboro,  Georgia,  include  real  property,  plant  and  equipment  that  we  lease  from  the 
Development Authority of Wilkinson County.  The original lease was executed in 1997 and was last amended in 2008.  The term of 
the current lease, which covers both locations was automatically extended through November 1, 2021.  Under the terms of the lease, 
we are responsible for all costs incurred in connection with the premises, including costs of construction of the plant and equipment.  
At the termination of the lease, title to all of the real property, plant and equipment is to be conveyed to us in exchange for nominal 
consideration.  We have the right to purchase the property, plant and equipment at any time during the term of the lease for a nominal 
price.

The Marshfield, Wisconsin sand processing plant, which became operational during 2012, is located on land owned by us.

We own or otherwise utilize distribution facilities in multiple locations around the world.  See “Item 1. Business – Distribution.”

We own approximately 2,957 acres of land and leasehold interests near our plants in Georgia and Alabama.  The land contains 
raw  material  for  use  in  the  production  of  our  lightweight  ceramic  proppants.    We  also  hold  approximately  469  acres  of  land  and 
leasehold interests in Wisconsin.

AGPI owns its service facility located in Decatur, Texas, and leases other regional service facilities within the United States.

Management’s Discussion and Analysis of Financial Condition and Results of Operations

Executive Level Overview

CARBO Ceramics Inc. is a global technology company that provides products and services to the oil and gas, industrial, and 

environmental markets to enhance value for its clients.

The Company conducts its business within two operating segments: 1) Oilfield and Industrial Technologies and Services and 2) 

Environmental Technologies and Services.  

The Company’s Oilfield and Industrial Technologies and Services segment manufactures and sells ceramic technology products 
and services, base ceramic proppant and frac sand for both the oilfield and industrial sectors.  The products have different technology 
features and product characteristics, which vary based on the application for which they are intended to be used.  The various ceramic 
products’ manufacturing processes are similar.

Oilfield  ceramic  technology  products,  base  ceramic  proppant  and  frac  sand  proppant  are  manufactured  and  sold  to  pressure 
pumping companies and oil and gas operators for use in the hydraulic fracturing of natural gas and oil wells.  Hydraulic fracturing is 
the  most  widely  used  method  of  increasing  production  from  oil  and  natural  gas  wells.  The  hydraulic  fracturing  process  consists  of 
pumping fluids down a natural gas or oil well at pressures sufficient to create fractures in the hydrocarbon-bearing rock formation.  A 
granular  material,  called  proppant,  is  suspended  and  transported  in  the  fluid  and  fills  the  fracture,  “propping”  it  open  once  high-
pressure  pumping  stops.  The  proppant  filled  fracture  creates  a  conductive  channel  through  which  the  hydrocarbons  can  flow  more 
freely from the formation to the well and then to the surface.

There are three primary types of proppant that can be utilized in the hydraulic fracturing process: sand, resin coated sand and 
ceramic.  Sand  is  the  least  expensive  proppant,  resin-coated  sand  is  more  expensive  and  ceramic  proppant  is  typically  the  most 
expensive.  We believe the higher initial cost of ceramic proppant is justified by the fact that its use in certain well conditions typically 
results in an increase in the production rate of oil and natural gas, an increase in the total oil or natural gas that can be recovered from 
the  well  and,  consequently,  an  increase  in  cash  flow  for  the  operators  of  the  well.  The  increased  production  rates  are  primarily 
attributable to the higher strength and more uniform size and shape of ceramic proppant versus alternative materials.  We are one of 
the world’s largest suppliers of ceramic proppant.

Through  our  wholly-owned  subsidiary  StrataGen,  Inc.,  we  promote  increased  production  and  EUR  of  oil  and  natural  gas  by 
selling a widely used fracture stimulation software under the brand FracPro, and providing fracture design and consulting services to 
oil and natural gas E&P companies under the brand StrataGen.

FracPro  provides  a  suite  of  stimulation  software  solutions  used  for  designing  fracture  treatments  and  for  on-site  real-time 
analysis.  Use  of  FracPro  enables  our  clients  to  optimize  stimulation  jobs  to  enhance  oil  and  gas  production.  FracPro  has  been 
integrated with third-party reservoir simulation software, furthering its reach and utility.

The  StrataGen  consulting  team  works  with  operators  around  the  world  to  help  optimize  well  placement,  fracture  treatment 
design and production enhancement.  The broad range of expertise of the StrataGen consultants includes: fracture treatment design; 
completion support; on-site treatment supervision; quality control; post-treatment evaluation and optimization; reservoir and fracture 
studies; rock mechanics and software application and training.

Our industrial ceramic technology products are manufactured and sold to industrial companies.  These products are designed for 

use in various industrial technology applications, including but not limited to casting and milling.

We also produce industrial products at our manufacturing facilities for third parties under tolling arrangements.  These products 
so  far  have  been  primarily  used  in  industrial,  or  agricultural  applications.  Contract  manufacturing  has  led  to  increased  revenue 
generation.  We  continue  to  develop  additional  opportunities  within  the  industrial,  agricultural  and  oil  and  gas  industries  to  grow 
revenue, and reduce our plant’s slowing and idling costs.

Our Environmental Technologies and Services segment is intended to protect operators’ assets, minimize environmental risks, 
and lower lease operating expense (“LOE”).   AGPI, the only subsidiary of ours to operate in this segment, provides spill prevention, 
containment and countermeasure systems for the oil and gas industry.  AGPI uses proprietary technology to make products designed 
to enable its clients to extend the life of their storage assets, reduce the potential for hydrocarbon spills and provide containment of 
stored materials.  

International revenues represented 19% and 21% of total revenues in 2018 and 2017, respectively.

Operating profit margin for our ceramic business is principally impacted by sales volume, product mix, sales price, distribution 
costs,  manufacturing  costs,  including  natural  gas,  and  our  production  levels  as  a  percentage  of  our  capacity.    The  level  of  selling, 
general and administrative spending, as well as other operating expenses, can also impact operating profit margins.  

18

As a result of the depressed commodity price we continued to experience in 2018, there has been a negative impact on industry 
activity levels which has in turn negatively impacted the demand for ceramic proppant, so we continue to focus on cash preservation 
and cost reduction strategies.  See “Item 1 - Business” and “Item 1A - Risk Factors”.

Although most direct manufacturing expenses have been relatively stable or predictable over time, we have historically experienced 
volatility in the cost of natural gas used in the production of our products.  In an effort to mitigate volatility in the cost of natural gas 
purchases and reduce exposure to short term spikes in the price of this commodity, we contracted in advance for portions of our future 
natural  gas  requirements.   Due  to  the  severe  decline  in  industry  activity  beginning  in  early  2015,  we  significantly  reduced  production 
levels and consequently did not take delivery of all of the contracted natural gas quantities.  As a result, we had accounted for the relevant 
contracts as derivative instruments.  However, as of December 31, 2018, our last derivative contract expired and no future natural gas 
obligations existed.

General Business Conditions

The oilfield portion of our Oilfield and Industrial Technologies and Services segment is impacted by the number of natural gas 
and oil wells drilled in North America, and the need to hydraulically fracture these wells.  Current demand for proppant is extremely 
dynamic.  In addition to rig counts and commodity prices, the oilfield portion is also significantly affected by a host of other factors, 
including but not limited to (a) completion activity, which is not necessarily correlated with rig count, (b) customer preferences, (c) 
new  product  and  technology  adoption,  (d)  imports  and  competition,  including  the  cost  of  competing  products,  (e)  changes  in  the 
product  mix  of  what  we  sell,  (f)  costs  of  developing  our  products  and  services  and  running  our  business,  and  (g)  changes  in  our 
strategy and execution.  In markets outside North America, sales of our products are also influenced by the overall level of drilling and 
hydraulic fracturing activity.  Furthermore, because the decision to use ceramic proppant is based on comparing the higher initial costs 
to the future value derived from increased production and recovery rates, our business is influenced by the current and expected prices 
of natural gas and oil.

Beginning in late 2014, a severe decline in oil and continued decline in natural gas prices led to a significant decline in oil and 
natural  gas  industry  drilling  activities  and  capital  spending.    During  2018,  however,  the  average  price  of  West  Texas  Intermediate 
(“WTI”) crude oil rose 28% to $64.94 per barrel compared to $50.88 per barrel in 2017.  The average North American rig count also 
rose 13% in 2018 to 1,222 rigs compared to 1,081 rigs in 2017.  Despite these improvements, E&P operators continued to use lowest-
cost  completions,  a  trend  that  we  expect  to  continue  in  2019,  as  our  customers  remain  under  pressure  to  consider  lower  cost 
alternatives,  notwithstanding  the  superior  performance  results  of  our  products.    These  events,  along  with  an  oversupplied  ceramic 
proppant market and depressed oil and natural gas prices, kept demand and average prices low for our proppants.

Beginning  early  in  2015,  we  implemented  a  number  of  initiatives  to  preserve  cash  and  lower  costs,  including:  (1)  reducing 
workforce across our organization, (2) lowering our production output levels in order to align with lower demand, including through 
idling and mothballing of some of our production facilities (3) limiting capital expenditures and (4) eliminating dividends.  As a result 
of operating some of our plants below their normal production capacity, we expensed $32.5 million of production overhead costs in 
excess of amounts that would have been allocated to each unit of production at normal production levels.  We continue to rationalize 
headcount as needed.  

Our Environmental Technologies and Services segment is also impacted by the global drilling and hydraulic fracturing activity, 

and has been negatively impacted by the significant decline in oil and natural gas industry drilling activities and capital spending.

On  December  31,  2018,  we  received  net  proceeds  of  $22.1  million  relating  to  the  sale  of  our  Millen,  Georgia  plant.    After 
consideration  of  certain  post-closing  matters  and  retained  liabilities  associated  with  the  sale,  we  expect  net  cash  proceeds  to 
approximate $15.7 million. 

Throughout our history, base ceramic was our dominant source of revenue.  In 2014, base ceramic represented approximately 
80%  of  our  total  revenue.    In  2018,  it  represented  approximately  20%.    The  decline  is  representative  of  the  pressure  operating 
companies  are  under  to  produce  at  the  lowest  cost  possible,  often  at  the  expense  of  long  term  productivity.    In  response,  we  are 
undergoing a strategic transformation to (1) diversify revenue streams, (2) return the Company to profitability by growing revenue and 
reducing costs, and (3) growing the business with minimal capital investments.  Our transformation strategy has showed solid progress 
as we continue to grow industrial and technology revenues, as well as reduce costs.

Critical Accounting Policies

Our  Consolidated  Financial  Statements  are  prepared  in  accordance  with  accounting  principles  generally  accepted  in  the  U.S., 
which require us to make estimates and assumptions (see Note 1 to the Consolidated Financial Statements).  We believe that, of our 
significant accounting policies, the following may involve a higher degree of judgment and complexity.

19

Revenue  is  recognized  when  title  passes  to  the  customer  (generally  upon  delivery  of  products)  or  at  the  time  services  are 
performed.    We  generate  a  significant  portion  of  our  revenues  and  corresponding  accounts  receivable  from  sales  to  the  petroleum 
pressure pumping industry.  In addition, we generate a significant portion of our revenues and corresponding accounts receivable from 
sales  to  two  major  customers,  both  of  which  are  in  the  petroleum  pressure  pumping  industry.    As  of  December  31,  2018, 
approximately 26% of the balance in trade accounts receivable was attributable to those two customers.  We record an allowance for 
doubtful accounts based on our assessment of collectability risk and periodically evaluate the allowance based on a review of trade 
accounts receivable.  Trade accounts receivable are periodically reviewed for collectability based on customers’ past credit history and 
current financial condition, and the allowance is adjusted, if necessary.  If the economic downturn in the petroleum pressure pumping 
industry  worsens  or  does  not  materially  improve  or,  for  some  other  reason,  any  of  our  primary  customers  were  to  experience 
significant adverse conditions, our estimates of the recoverability of accounts receivable could be reduced by a material amount and 
the allowance for doubtful accounts could be increased by a material amount.  As of December 31, 2018, the allowance for doubtful 
accounts totaled $1.3 million.

We  value  inventory  using  the  weighted  average  cost  method.    Assessing  the  ultimate  realization  of  inventories  requires 
judgments  about  future  demand  and  market  conditions.    We  regularly  review  inventories  to  determine  if  the  carrying  value  of  the 
inventory exceeds net realizable value and we record an adjustment to reduce the carrying value to net realizable value, as necessary.  
Future changes in demand and market conditions could cause us to be exposed to additional obsolescence or slow moving inventory.  
If actual market conditions are less favorable than those projected by management, lower of cost or net realizable value adjustments 
may be required.  There were no lower of cost or net realizable value inventory adjustments for the years ended December 31, 2018 
and 2017.

Income  taxes  are  provided  for  in  accordance  with  ASC  Topic  740,  “Income  Taxes”.    This  standard  takes  into  account  the 
differences  between  financial  statement  treatment  and  tax  treatment  of  certain  transactions.    Deferred  tax  assets  (“DTAs”)  and 
liabilities (“DTLs”) are recognized for the future tax consequences attributable to differences between the financial statement carrying 
value of existing assets and liabilities and their respective tax bases.  Deferred tax assets and liabilities are measured using enacted tax 
rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.  
The effect of a change in tax rates is recognized as income or expense in the period that includes the enactment date.  This calculation 
requires us to make certain estimates about our future operations.  Changes in state, federal and foreign tax laws, as well as changes in 
the Company’s financial condition, could affect these estimates.

Accounting Standards Codification (“ASC”) Topic 740, Income Taxes, provides the carrying value of DTAs should be reduced 
by the amount not expected to be realized.  A company should reduce deferred tax assets by a valuation allowance if, based on the 
weight of all available evidence, it is no longer more likely than not that some portion or all of the deferred tax assets will be realized.  
The valuation allowance should be sufficient to reduce the deferred tax asset to the amount that is more likely than not to be realized.  
ASC 740 requires all available evidence, both positive and negative, be considered to determine whether a valuation allowance for 
deferred tax assets is needed in the financial statements.  Additionally there can be statutory limitations and losses also assessed on the 
deferred tax assets should certain conditions arise.  

We believe it is more likely than not that a portion of our deferred tax assets will not be realized in the future.  Accordingly, we 
have a $72.4 million valuation allowance against our deferred tax assets.  Our assessment of the realizability of our deferred tax assets 
is  based  on  the  weight  of  all  available  evidence,  both  positive  and  negative,  including  future  reversals  of  deferred  tax  liabilities.  
Income tax expense was $0.9 million, or 1.2% of pretax loss, for the year ending December 31, 2018 compared to income tax benefit 
of $2.0 million, or 0.8% of pretax loss, for the same period in 2017.  

In December 2017, the Tax Cuts and Jobs Act (“Tax Legislation”) was enacted.  The Tax Legislation significantly revises the 
U.S. corporate income tax by, among other things, lowering corporate income tax rates, implementing the territorial tax system and 
imposing  a  repatriation  tax  on  deemed  repatriated  earnings  of  foreign  subsidiaries.    In  accordance  with  the  Tax  Legislation,  we 
recorded $28.2 million as additional income tax expense in the fourth quarter of 2017 related to the re-measurement of deferred tax 
assets  and  liabilities.    Additionally,  Staff  Accounting  Bulletin  No.  118  ("SAB  118")  was  issued  to  address  the  application  of  U.S. 
GAAP  in  situations  when  a  registrant  does  not  have  the  necessary  information  available,  prepared,  or  analyzed  (including 
computations) in reasonable detail to complete the accounting for certain income tax effects of the Act.  December 22, 2018 marked 
the end of the measurement period for purposes of SAB 118.  As such, we have completed the analysis based on legislative updates 
relating to the Tax Legislation.  No material changes to the provisional amounts recorded as of December 31, 2017 were identified.   
We continue to evaluate the impacts of the newly enacted global intangible low-taxed income (“GILTI”) provisions, which subject our 
foreign earnings to a minimum level of tax.  

While the Tax Legislation provides for a territorial tax system, beginning in 2018, it includes the global intangible low-taxed 
income (“GILTI”) provision.  The GILTI provisions require us to include in our U.S. income tax return foreign subsidiary earnings in 
excess of an allowable return on the foreign subsidiary’s tangible assets.  FASB guidance indicates that accounting for GILTI either as 

20

part of deferred taxes or as a period cost are both acceptable methods.  As of December 31, 2018, we have not recognized foreign 
earnings subject to GILTI.  An accounting policy will be elected in the first period in which the GILTI provision becomes applicable 
to us.

Long-lived assets, which include net property, plant and equipment, goodwill, intangibles and other long-term assets, comprise a 
significant  amount  of  the  Company’s  total  assets.    The  Company  makes  judgments  and  estimates  in  conjunction  with  the  carrying 
values of these assets, including amounts to be capitalized, depreciation and amortization methods and useful lives.  Additionally, the 
carrying values of these assets are periodically reviewed for impairment or whenever events or changes in circumstances indicate that 
the carrying amounts may not be recoverable.  An impairment loss is recorded in the period in which it is determined that the carrying 
amount  is  not  recoverable.    This  requires  the  Company  to  make  long-term  forecasts  of  its  future  revenues  and  costs  related  to  the 
assets subject to review.  These forecasts require assumptions about demand for the Company’s products and services, future market 
conditions and technological developments.  Significant and unanticipated changes to these assumptions could require a provision for 
impairment in a future period.

As a result of the sale of our Millen facility for less than the carrying value of each of our Toomsboro Georgia and Eufaula, 
Alabama facilities combined with the continued lowered demand for our base ceramic proppants, we evaluated those long-lived assets 
for possible impairment as of December 31, 2018.  We prepared an undiscounted cash flow analysis for these two asset groups.  The 
Eufaula, Alabama facility is part of our technology asset group which also includes our New Iberia, Louisiana facility, and as such, we 
evaluated  the  entire  technology  asset  grouping  for  impairment.    Key  assumptions  underlying  our  undiscounted  cash  flow  analysis 
included,  but  were  not  limited  to,  facility  utilization,  production  costs,  major  maintenance  and  long-term  sales  prices  for  products 
produced.    Based  on  these  analyses,  we  noted  that,  for  each  of  these  asset  groups,  the  carrying  value  was  below  the  sum  of  the 
undiscounted cash flows, and thus no impairment was required. 

Low  production  levels  triggered  the  component  of  our  inventory  accounting  policy  relating  to  operating  at  production  levels 
below  normal  capacity.    To  determine  the  amount  of  production  costs  that  we  expense  during  each  period,  the  Company  allocates 
fixed production overheads to the costs of conversion based on the normal capacity of each production facility, generally considered to 
be 65% of a facility's stated capacity or higher.

When a production facility operates at normal capacity, all of its fixed production overheads are allocated to costs of conversion 
of each product manufactured, based on the actual level of production.  This determination is made facility-by-facility on a monthly 
basis in order to calculate the initial measurement value to recognize as cost of goods produced in a month by a given facility.

When  a  facility's  total  production  in  a  month  drops  below  65%  of  its  normal  capacity,  it  is  considered  to  be  operating  at  an 
abnormally low production level.  In such cases, each unit of production receives an allocation of fixed overheads in the amount that 
would have been allocated at the lower-end of normal capacity.  The remaining unallocated excess fixed overhead cost for the facility 
is recognized as expense in the period and classified as Cost of Sales.

Materials are the only variable component of production.  Plant labor and all other overhead costs incurred in the production of 
the Company's products are either semi-fixed or fixed in nature, therefore all are included in the monthly evaluation of costs allocable 
to costs of conversion at normal capacity.

The Company maintains a rate for each production facility that represents the maximum fixed production overhead cost per unit 
of  production  allocable  to  costs  of  conversion.    The  rates  are  based  on  an  analysis  of  a  recent  historical  period  considered 
representative of a normal operating environment in which the facility operated at normal capacity.  The maximum rate is calculated 
by recasting the fixed production overhead cost per unit of production on a pro forma basis as if the facility had operated at the lower-
end  threshold  of  its  range  of  normal  capacity,  generally  65%  of  stated  capacity.    The  current  rates  are  based  on  2014  as  the 
representative year.  Implied in this method is the assumption that 2014 production costs relative to sales prices yield a normal profit 
margin.  A significant, permanent deterioration in the average selling prices of the Company’s products could result in a significant 
lowering of the rates, thereby increasing the periodic charge.  The most recent period in which normal capacity was achieved was the 
year-ended December 31, 2014.

For the year ended December 31, 2018, we reported net loss of $75.4 million, which was a 70% improvement compared to the 
$253.1 million net loss reported in the previous year.  Excluding the impact of income taxes, other operating (income) expense, and 
the loss on the sale of our Russian proppant business and Millen plant, net loss in 2018 improved by $30.4 million, or 30%, primarily 
due to an increase in sales of technology and industrial products and services and an increase in sales of Environmental Technologies 
and Services.  In addition, slowing and idling costs were reduced by $8.2 million, which was partially offset by an increase of $1.3 
million in severance and other charges as compared to 2017.

Our  cost  of  sales  related  to  our  Oilfield  and  Industrial  Technologies  and  Services  segment  consists  of  manufacturing  costs, 
packaging  and  transportation  expenses  associated  with  the  delivery  of  our  products  to  our  customers  and  handling  costs  related  to 
maintaining  finished  goods  inventory  and  operating  our  remote  stocking  facilities.    Variable  manufacturing  costs  include  raw 
materials, while labor, utilities and repair and maintenance supplies are semi-fixed.  Fixed manufacturing costs include depreciation, 
property taxes on production facilities, insurance and factory overhead.

Oilfield and Industrial Technologies and Services segment gross loss for the year ended December 31, 2018 was $28.4 million, 
or (16)% of revenues, compared to gross loss of $56.4 million, or (34)% of revenues, for 2017.  The improvement in gross loss in 
2018 was primarily attributable to a shift in sales mix to more profitable technology and industrial products and lower slowing and 
idling production costs and derivative gains in the year due to changes in the fair value of the derivative liability and changes in the 
NYMEX forward price strip prices.  We expect to incur slowing and idling production costs in the future until our production levels 
return to normal capacity.   

Environmental Technologies and Services segment gross profit for the year ended December 31, 2018 was $5.8 million, or 18% 
of revenues, compared to gross profit of $3.1 million, or 13% of revenues, for 2017.  This increase in gross profit was primarily the 
result of the increase in sales.

Depreciation and amortization was $32.3 million for the year ended December 31, 2018 compared to $41.7 million for the same 
period  in  2017.  This  decrease  was  largely  due  to  the  impairment  recorded  on  our  Millen  facility  during  the  third  quarter  of  2017, 
which reduced future depreciation expense.  The Millen facility was sold in December 2018.

Oilfield  and  Industrial  Technologies  and  Services  segment  SG&A  was  $36.5  million  for  the  year  ended  December  31,  2018 
compared  to  $37.4  million  for  2017.    The  decrease  in  SG&A  expenses  primarily  resulted  from  a  decrease  in  administrative  and 
research  and  development  expenses  partially  offset  by  an  increase  in  sales  and  marketing  expenses  to  support  the  growth  of  this 
segment.  

Depreciation and amortization was $2.3 million for the year ended December 31, 2018 compared to $2.6 million for 2017.  This 
decrease was the result of certain assets becoming fully depreciated and fully amortized.  Loss on sale of Millen plant was $2.3 million 
for the year ended December 31, 2018 compared to none in 2017.  This was the result of the sale of our Millen plant that occurred in 
late  2018.    Loss  on  sale  of  Russian  proppant  business  was  $0.4  million  for  the  year  ended  December  31,  2018  compared  to  $26.7 
million in 2017.  Both periods related to the sale of our Russian proppant business.  The loss in 2018 was related to settling a $4.0 
million receivable that was owed to us for $3.6 million.  Other operating income was $0.3 million for the year ended December 31, 
2018 compared to other operating expense of $125.8 million for 2017.   Other operating income in 2018 was primarily related to gain 
on  asset  sales  partially  offset  by  other  operating  expenses.    Other  operating  expense  in  2017  was  related  to  an  impairment  of  our 
Millen,  Georgia  proppant  manufacturing  facility.    As  a  percentage  of  revenues,  Oilfield  and  Industrial  Technologies  and  Services 
segment SG&A expenses for 2018 decreased to 20% compared to 23% in 2017, primarily due to the increase in revenues.

Outlook

We are very pleased with the profitable growth in our Industrial and Environmental business sectors.  The growth of these two sectors 
should result in a balanced portfolio that is less susceptible to swings in oil and gas commodity prices.  We are also pleased with the 
oilfield technology products and services profitable growth, and expect to retain our leadership position in those products and services.  

In  the  Oilfield  sector,  E&P  operators’  focus  on  free  cash  flow,  coupled  with  recent  oil  price  volatility,  creates  a  less  than  certain 
environment  with  regard  to  drilling  and  completion  spend  in  2019.    Some  industry  analysts  are  predicting  2019  drilling  and 
completion  spend  to  be  down  high  single  digits  on  a  percentage  basis  compared  to  2018.    However,  we  are  seeing  positive  signs 
internationally that should bode well for our oilfield sector products.  

The Industrial sectors provide a large, multi-year growth opportunity for CARBO.  In the mining sector, more companies have started 
increasing their operating and capital spend, which supports our CARBOGRIND product growth.  In the foundry industry, the value 
our  products  bring  to  improve  our  client’s  end-product  quality,  along  with  the  need  to  comply  with  OSHA  Permissible  Exposure 
Limits (PEL) silicosis regulations, supports our ACCUCAST product growth.  In both these sectors, and in numerous other Industrial 
sectors, our ceramic technology products are seeing market share growth.

The  Environmental  sector  continues  to  see  growth,  as  companies  in  various  industry  sectors  continue  to  be  more  environmentally 
conscious.  This provides us with a multi-year growth opportunity, in which we will put a strong focus on growing at high rates in 
Industrial sectors. 

We anticipate our 2019 consolidated revenue to be similar to 2018.

We expect continued strong growth for our international ceramic technology sales in 2019.  Demand for our technology continues to 
increase in South America, as well as in Europe, Africa and the Middle East.  In North America, the opportunity set for our ceramic 
technology sales remains strong, with KRYPTOSPHERE HD projects currently weighted more to the second half of the year.

On the fracture technology design and analysis front, demand for our StrataGen consultants, and our FracPro software, is expected to 
remain strong as our clients utilize these offerings to optimize their completion designs and return economics. 

At this time, we anticipate base ceramic sales and frac sand sales to decrease single digits on a percentage basis, similar to the lower 
industry  expectations  for  drilling  and  completion  spend.    For  base  ceramics,  we  continue  to  drive  business  model  changes  towards 
production on demand, along with upfront cash commitments.  For frac sand, a high percentage of our sand capacity is under contract, 
from which we are also benefiting from the use of our rail cars and distribution center. 

We  expect  strong  double  digit  growth  in  industrial  revenues  in  2019  through  continued  growth  of  our  ceramic  media  in  both  the 
grinding and foundry markets.   Our industrial ceramic client list is expanding globally, and should lead to improved market share for 
our technology products.  We are also developing new markets while expanding the existing markets we sell into through a broader 
range of technology product offerings.

Our  PicOnyx  Inc.  investment  is  off  to  a  strong  start.    We  recently  initiated  the  first  phase  of  the  manufacturing  process.    M-Tone 
pigment is expected to be in the market during the first half of 2019, and we expect production to ramp up over the course of the year.

CARBO has world class manufacturing expertise.  This manufacturing expertise is used to develop solutions for our clients.  There are 
a number of contract manufacturing opportunities in the queue.  We expect to grow both in revenue and by expanding the types of 
products we produce.  The benefit of expanding our products has the potential to be significant as these projects take idled assets and 
turn them from cash consumers to cash producers.

Growth in product sales and expanding our reach outside the oilfield should result in revenue growth for ASSETGUARD in 2019.  
We  are  increasing  resources  specifically  dedicated  to  growing  industrial  and  other  end  market  sales.    ASSETGUARD  continues  to 
lead the industry in developing technology products to address the ongoing challenges of our clients. 

Progress  on  our  transformation  strategy  will  continue  in  2019  as  we  continue  to  focus  on  diversifying  our  revenue  streams, 
maximizing profitability across the businesses, and maintaining healthy cash levels.  We expect to be cash neutral in 2019, excluding 
planned debt repayments.

Liquidity and Capital Resources

At  December  31,  2018,  we  had  cash  and  cash  equivalents  and  restricted  cash  of  $83.3  million  compared  to  cash  and  cash 
equivalents and restricted cash of $78.4 million at December 31, 2017.  During the year ended December 31, 2018, we received net 
proceeds from asset sales of $27.5 million primarily related to the sale of our Millen plant, additional proceeds received from the sale 
of our Russian proppant business, as well as other asset sales.  Net cash provided by financing activities was $1.0 million for the year 
ended  December  31,  2018.    Uses  of  cash  included  $21.6  million  in  operating  activities  and  $2.0  million  for  capital  expenditures.  
There were no major capital spending projects in 2018.  Capital spending in 2018 primarily related to various plant maintenance as 
well as equipment purchases for the environmental business.

We estimate our total capital expenditures in 2019 will be less than $5.0 million.  In April 2019, we are required to repay the 
Notes with two of our directors totaling $27 million.  In addition, within 270 days of completion of all post-closing matters relating to 
the sale of our Millen, Georgia plant, we are required to use 100% of the Net Cash Proceeds (as defined in the credit agreement) from 
the sale to either (1) prepay the outstanding principal amount of the Term Loans or (2) reinvest in fixed or capital assets of any Credit 
Party.  We are currently evaluating these options, and we may engage in negotiations with our lenders with respect to other options.  
As of December 31, 2018, the Company has classified $15.7 million of the outstanding debt as current liabilities, which represents an 
estimate  of  the  Net  Cash  Proceeds,  including  all  post-closing  matters  and  retained  liabilities  that  will  be  repaid  over  a  multi-year 
period, that we would be required to prepay if we do not reinvest in fixed or capital assets.  As a result of the required repayment of 
the Director Notes and required use of the Millen Net Cash Proceeds, we are committed to using approximately $43 million of our 
unrestricted cash and cash equivalents during 2019.

The  Company  anticipates  that  cash  on  hand  will  be  sufficient  to  meet  planned  operating  expenses,  debt  payments,  and  other 
cash needs for the next 12 months from the date of this Form 10-K.  The Company’s view regarding sufficiency of cash and liquidity 
is primarily based on our financial forecast for the next twelve months, which is impacted by various assumptions regarding demand 
and sales prices for our products.  Generally, we expect demand for our products and the sales prices to remain consistent in 2019 and 
the  first  quarter  of  2020  compared  to  2018.    We  also  expect  to  decrease  our  operating  costs  in  2019  and  the  first  quarter  of  2020 
compared to 2018 while improving our cash position through continued balance sheet management.  Our financial forecasts are based 
on  estimates  of  customer  demand,  which  is  highly  volatile  in  the  current  operating  environment,  and  we  have  no  committed  sales 
backlog with our customers.  As a result, there is inherent uncertainty in our forecasts.  In the event that we experience lower customer 
demand, lower prices for our products and services, or higher expenses than we have forecasted or if we underperform relative to our 
forecast, we could experience negative cash flows from operations, as has been the case in prior years, which would reduce our cash 
balances and liquidity.  See Item 1A. Risk Factors – We may not have sufficient cash and/or be able to access liquidity alternatives in 
the credit and capital markets to meet our liquidity needs.

Off-Balance Sheet Arrangements

We had no off-balance sheet arrangements as of December 31, 2018.

(a)

Evaluation of Disclosure Controls and Procedures

Disclosure  controls  and  procedures  are  designed  to  ensure  that  information  required  to  be  disclosed  in  the  reports  filed  or

the time periods specified in the SEC’s rules and forms.  Disclosure controls and procedures include, without limitation, controls and 
procedures designed to ensure that information required to be disclosed in the reports filed under the Exchange Act is accumulated and 

25

communicated  to  management,  including  the  Chief  Executive  Officer  and  Chief  Financial  Officer,  as  appropriate  to  allow  timely 
decisions regarding required disclosure.

As of December 31, 2018, management carried out an evaluation, under the supervision and with the participation of the Chief 
Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the Company’s disclosure controls 
and procedures.  There are inherent limitations to the effectiveness of any system of disclosure controls and procedures.  Accordingly, 
even effective disclosure controls and procedures can only provide reasonable assurances of achieving their control objectives.  Based 
upon and as of the date of that evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that the Company’s 
disclosure controls and procedures were effective to ensure that information required to be disclosed by the Company in the reports it 
files  or  submits  under  the  Exchange  Act  is  recorded,  processed,  summarized  and  reported,  within  the  time  periods  specified  in  the 
SEC’s rules and forms, and to ensure that information required to be disclosed by the Company in the reports that it files or submits 
under the Exchange Act is accumulated and communicated to the Company’s management, including its Chief Executive Officer and 
Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

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 Securities Exchange Act of 1934.  The Company’s internal control over financial reporting is 
designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for 
external reporting purposes in accordance with U.S. generally accepted accounting principles.

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.

Management,  including  our  Chief  Executive  Officer  and  our  Chief  Financial  Officer,  assessed  the  effectiveness  of  the 
Company’s internal control over financial reporting as of December 31, 2018.  In making this assessment, it used the criteria set forth 
by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission  (COSO) in  Internal  Control–Integrated  Framework 
(2013).  Based on its assessment and those criteria, management has concluded that the Company maintained effective internal control 
over financial reporting as of December 31, 2018.

The  Company’s  independent  registered  public  accounting  firm,  Ernst  &  Young  LLP,  has  issued  an  attestation  report  on  the 

Company's internal control over financial reporting.  That report is included herein.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of CARBO Ceramics Inc.

Opinion on Internal Control over Financial Reporting

We have audited CARBO Ceramics Inc.’s internal control over financial reporting as of December 31, 2018, based on criteria 
established  in  Internal  Control—Integrated  Framework  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway 
Commission (2013 framework) (the COSO criteria). In our opinion, CARBO Ceramics Inc. (the Company) maintained, in all material 
respects, effective internal control over financial reporting as of December 31, 2018, based on the COSO criteria.

We  also  have  audited,  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board  (United  States) 
(PCAOB), the consolidated balance sheets of the Company as of December 31, 2018 and 2017, the related consolidated statements of 
operations,  comprehensive  loss,  shareholders’  equity  and  cash  flows  for  the  years  then  ended,  and  the  related  notes  and  our  report 
dated February 28, 2019 expressed an unqualified opinion thereon.

Basis for Opinion

The  Company’s  management  is  responsible  for  maintaining  effective  internal  control  over  financial  reporting  and  for  its 
assessment  of  the  effectiveness  of  internal  control  over  financial  reporting  included  in  the  accompanying  Management’s  Report  on 
Internal  Control  Over  Financial  Reporting.  Our  responsibility  is  to  express  an  opinion  on  the  Company’s  internal  control  over 
financial reporting based on our audit. We are a public accounting firm registered with the 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material 
respects.

Our  audit  included  obtaining  an  understanding  of  internal  control  over  financial  reporting,  assessing  the  risk  that  a  material 
weakness  exists,  testing  and  evaluating  the  design  and  operating  effectiveness  of  internal  control  based  on  the  assessed  risk,  and 
performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable 
basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A  company’s  internal  control  over  financial  reporting  is  a  process  designed  to  provide  reasonable  assurance  regarding  the 
reliability  of  financial  reporting  and  the  preparation  of  financial  statements  for  external  purposes  in  accordance  with  generally 
accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) 
pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the 
assets of the company; (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  management  and  directors  of  the  company;  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 the financial statements.

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

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of CARBO Ceramics Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of CARBO Ceramics Inc. (the Company) as of December 31, 
2018  and  2017,  the  related  consolidated  statements  of  operations,  comprehensive  loss,  shareholders’  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 financial position of the Company at December 31, 2018 
and  2017,  and  the  results  of  its  operations  and  its  cash  flows  for  the  years  then  ended  in  conformity  with  U.S.  generally  accepted 
accounting principles.

We  also  have  audited,  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board  (United  States) 
(PCAOB), the Company’s internal control over financial reporting as of December 31, 2018, based on criteria established in Internal 
Control—Integrated  Framework  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission  (2013 
framework) and our report dated February 28, 2019 expressed an unqualified opinion thereon.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on 
the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required 
to  be  independent  with  respect  to  the  Company  in  accordance  with  the  U.S.  federal  securities  laws  and  the  applicable  rules  and 
regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the 
audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or 
fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due 
to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence 
regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used 
and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe 
that our audits provide a reasonable basis for our opinion.

Significant Accounting Policies

Description of Business

CARBO Ceramics Inc. (the “Company”) was formed in 1987 and is a global technology company that provides products and 
services to the oil and gas, industrial, and environmental markets to enhance value for its clients.  The Company has production plants 
in:  New  Iberia,  Louisiana;  Eufaula,  Alabama;  McIntyre,  Georgia;  and  Toomsboro,  Georgia;  and  a  sand  processing  facility  in 
Marshfield, Wisconsin.  The Company sold its Millen, Georgia production plant in December 2018.  The Company sells its proppant 
products through pumping service companies that perform hydraulic fracturing for oil and gas companies.  In addition, the Company 
sells  ceramic  media  to  industrial  markets.    Finished  goods  inventories  are  stored  at  the  plant  sites  and  various  domestic  and 
international  remote  distribution  facilities.    The  Company  also  provides  one  of  the  industry’s  most  widely  used  hydraulic  fracture 
simulation software FracPro, as well as hydraulic fracture design and consulting services.  In addition, the Company provides a broad 
range of technologies for spill prevention, containment and countermeasures to oil and gas and industrial markets.

Beginning in late 2014, a severe decline in oil and natural gas prices led to a significant decline in oil and natural gas industry 
drilling activities and capital spending.  Beginning in 2015, the Company implemented a number of initiatives to preserve cash and 
lower  costs,  including:  reducing  workforce  across  the  organization,  lowering  production  output  levels  in  order  to  align  with  lower 
demand, limiting capital expenditures and reducing dividends.  The Company incurred severance costs of $924 and $287 during 2018 
and 2017, respectively, as a result of these actions.

As of December 31, 2018, we are producing technology ceramic proppants from our Eufaula, Alabama manufacturing facility, 
base  ceramic  proppants  from  our  Toomsboro,  Georgia  manufacturing  facility,  and  processing  sand  at  our  Marshfield,  Wisconsin 
facility.    We  are  also  producing  ceramic  media  at  our  McIntyre,  Georgia  and  Eufaula,  Alabama  facilities.    We  are  also  using  our 
Toomsboro, Georgia facility for contract manufacturing.  In addition, we produce resin-coated ceramic proppants at our New Iberia, 
Louisiana facility.  The Company continues to assess liquidity needs and manage cash flows.  As a result of the steps the Company 
has taken to enhance its liquidity, the Company currently believes that cash on hand and cash flows from operations will enable the 
Company to meet its working capital, capital expenditure, debt service and other funding requirements for at least one year from the 
date this Form 10-K is issued.  The Company’s view regarding sufficiency of cash and liquidity is primarily based on our financial 
forecast for 2019 and the first quarter of 2020, which is impacted by various assumptions regarding demand and sales prices for our 
products.  Generally, we expect demand for our products and the sales prices to remain consistent in 2019 and the first quarter of 2020 
compared to 2018, and this expectation is included within our financial forecast for 2019 and the first quarter of 2020.  We also expect 
to  decrease  our  operating  costs  in  2019  and  the  first  quarter  of  2020  compared  to  2018  while  improving  our  cash  position  through 
continued  balance  sheet  management.    Our  financial  forecasts  in  recent  periods  have  proven  less  reliable  given  customer  demand, 
which is highly volatile in the current operating environment and no committed sales backlog exists with our customers.  As a result, 
there is no guarantee that our financial forecast, which projects sufficient cash will be available to meet planned operating expenses 
and  other  cash  needs,  will  be  accurate.    In  the  event  that  the  Company  experiences  lower  customer  demand,  lower  prices  for  its 
products and services, or higher expenses than it forecasted or if the Company underperforms relative to its forecast, the Company 
could experience negative cash flows from operations, as has been the case in prior years, which would reduce its cash balances and 
liquidity.    

The  second  phase  of  the  retrofit  of  our  Eufaula,  Alabama  plant  with  the  new  KRYPTOSPHERE®  technology  has  been 
suspended until such time that market conditions improve enough to warrant completion.  As of December 31, 2018, the value of the 
assets  relating  to  this  project  totaled  approximately  82%  of  the  Company’s  total  construction  in  progress  and  the  project  is 
approximately 75% complete.  

Principles of Consolidation

The  consolidated  financial  statements  include  the  accounts  of  CARBO  Ceramics  Inc.  and  its  operating  subsidiaries.    All 

significant intercompany transactions have been eliminated.

Concentration of Credit Risk, Accounts Receivable and Other Receivables

The  Company  performs  periodic  credit  evaluations  of  its  customers’  financial  condition  and  generally  does  not  require 
collateral.    Receivables  are  generally  due  within  30  days.    The  majority  of  the  Company’s  receivables  are  from  customers  in  the 
petroleum pressure pumping industry, as well as industrial and environmental industries.  The Company establishes an allowance for 

F-9

doubtful  accounts  based  on  its  assessment  of  collectability  risk  and  periodically  evaluates  the  balance  in  the  allowance  based  on  a 
review of trade accounts receivable.  Trade accounts receivable are periodically reviewed for collectability based on customers’ past 
credit  history  and  current  financial  condition,  and  the  allowance  is  adjusted  if  necessary.    Credit  losses  historically  have  been 
insignificant.    The  allowance  for  doubtful  accounts  at  December  31,  2018  and  2017  was  $1,279  and  $1,602,  respectively.    Other 
receivables  were  $442  and  $546  as  of  December  31,  2018  and  2017,  respectively,  of  which  related  mainly  to  miscellaneous 
receivables in the United States.

Cash Equivalents

The  Company  considers  all  highly  liquid  investments  with  a  maturity  of  three  months  or  less  when  purchased  to  be  cash 

equivalents.  The carrying amounts reported in the balance sheet for cash equivalents approximate fair value.

Restricted Cash

A portion of the Company’s cash balance is restricted to its use in order to provide collateral primarily for letters of credit and 
funds held in escrow relating to the sale of its Millen plant.  As of December 31, 2018 and 2017, total restricted cash was $10,565 and 
$10,216, respectively.

Inventories

Inventories are stated at the lower of net realizable value or cost.  Finished goods inventories include costs of materials, plant 

labor and overhead incurred in the production of the Company’s products and costs to transfer finished goods to distribution centers.

The Company evaluated the carrying values of its inventories and concluded that no adjustments were required in 2018 or 2017.

Property, Plant and Equipment

Property,  plant  and  equipment  are  stated  at  cost.    Repair  and  maintenance  costs  are  expensed  as  incurred.    Depreciation  is 

computed on the straight-line method for financial reporting purposes using the following estimated useful lives:

Buildings and improvements.......................................................
Machinery and equipment ...........................................................
Land-use rights ............................................................................

15 to 30 years
3 to 30 years
30 years

The  Company  holds  approximately  2,957  acres  of  land  and  leasehold  interests  containing  kaolin  reserves  near  its  plants  in 
Georgia and Alabama.  The Company also holds approximately 469 acres of land and leasehold interests containing sand reserves near 
its  sand  processing  facility  in  Marshfield,  Wisconsin.    The  capitalized  costs  of  land  and  mineral  rights  as  well  as  costs  incurred  to 
develop such property are amortized using the units-of-production method based on estimated total tons of these reserves.

Impairment of Long-Lived Assets and Intangible Assets

Long-lived  assets  to  be  held  and  used  and  intangible  assets  that  are  subject  to  amortization  are  reviewed  for  impairment 
whenever events or circumstances indicate their carrying amounts might not be recoverable.  Recoverability is assessed by comparing 
the undiscounted expected future cash flows from the assets with their carrying amount.  If the carrying amount exceeds the sum of 
the undiscounted future cash flows an impairment loss is recorded.  The impairment loss is measured by comparing the fair value of 
the assets with their carrying amounts.  Intangible assets that are not subject to amortization are tested for impairment at least annually 
by comparing their fair value with the carrying amount and recording an impairment loss for any excess of carrying amount over fair 
value.  Fair values are generally determined based on discounted expected future cash flows or appraised values, as appropriate.  For 
additional information on the Company’s long-lived assets and intangible assets impairment assessment, please refer to Note 5 – Other 
Operating (Income) Expense.

Manufacturing Production Levels Below Normal Capacity

As a result of the Company substantially reducing manufacturing production levels, including by idling and mothballing certain 
facilities, the component of the Company’s accounting policy for inventory relating to operating at production levels below normal 
capacity  was  triggered  and  resulted  in  certain  production  costs  being  expensed  instead  of  being  capitalized  into  inventory.    The 
Company  expenses  fixed  production  overhead  amounts  in  excess  of  amounts  that  would  have  been  allocated  to  each  unit  of 

F-10

production  at  normal  production  levels.    For  the  years  ended  December  31,  2018  and  2017,  the  Company  expensed  $32,509  and 
$40,664, respectively, in production costs.

Capitalized Software

The  Company  capitalizes  certain  software  costs,  after  technological  feasibility  has  been  established,  which  are  amortized 

utilizing the straight-line method over the economic lives of the related products, generally not to exceed five years.

Goodwill

Goodwill represents the excess of the cost of companies acquired over the fair value of their net assets at the date of acquisition.  
Goodwill  relating  to  each  of  the  Company’s  reporting  units  is  tested  for  impairment  annually,  during  the  fourth  quarter,  as  well  as 
when  an  event,  or  change  in  circumstances,  indicates  an  impairment  is  more  likely  than  not  to  have  occurred.    For  additional 
information on the Company’s goodwill impairment assessment, please refer to Note 5 – Other Operating (Income) Expense.

Revenue Recognition

Revenue from proppant sales is recognized when title passes to the customer, generally upon delivery.  Revenue from consulting 
and contract manufacturing is recognized at the time service is performed.  Revenue from the sale of fracture simulation software is 
recognized when title passes to the customer at time of shipment.  Revenue from the sale of spill prevention services is recognized at 
the time service is performed.  Revenue from the sale of containment goods is recognized at the time goods are delivered.

Shipping and Handling Costs

Shipping and handling costs are classified as cost of sales.  Shipping costs consist of transportation costs to deliver products to 

customers.  Handling costs include labor and overhead to maintain finished goods inventory and operate distribution facilities.

Cost of Start-Up Activities

Start-up activities, including organization costs, are expensed as incurred.  There were no start-up costs for 2018 and 2017.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires 
management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes.  
Actual results could differ from those estimates.

Research and Development Costs

Research  and  development  costs  are  charged  to  operations  when  incurred  and  are  included  in  Selling,  General  and 

Administrative expenses.  The amounts incurred in 2018 and 2017 were $3,823 and $4,417, respectively.

New Accounting Pronouncements

In  February  2016,  the  FASB  issued  ASU  No.  2016-02,  “Leases  (Topic  842),”  which  amends  current  lease  guidance.    This 
guidance requires, among other things, that lessees recognize the following for all leases (with the exception of short-term leases) at 
the commencement date: (1) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on 
a  discounted  basis;  and  (2)  a  right-of-use  asset,  which  is  an  asset  that  represents  the  lessee’s  right  to  use,  or  control  the  use  of,  a 
specified asset for the lease term.  Lessees and lessors must apply a modified retrospective transition approach for leases existing at, or 
entered  into  after,  the  beginning  of  the  earliest  comparative  period  presented  in  the  financial  statements.    In  July  2018,  the  FASB 
issued ASU No. 2018-11, “Leases (Topic 842): Targeted Improvements”, which simplifies the implementation by allowing entities 
the  option  to  instead  apply  the  provisions  of  the  new  guidance  at  the  effective  date,  without  adjusting  the  comparative  periods 
presented.  The new lease guidance will be effective for the interim and annual periods beginning after December 15, 2018 with early 
adoption  permitted.    The  Company  adopted  this  guidance  effective  January  1,  2019  without  adjusting  the  comparative  periods.  
During the first quarter of 2019, the Company expects its ROU asset will be within a range of $54,000 to $60,000 and its total lease 
liability  will  be  within  a  range  of  $62,000  to  $68,000.    In  addition,  upon  implementation,  the  Company’s  deferred  rent  balances, 
recorded primarily within other long-term liabilities and accrued expenses as of December 31, 2018, of approximately $8,300 will be 

F-11

offset  with  the  lease  liability.    The  Company  has  implemented  a  lease  accounting  system  for  accounting  for  leases  under  the  new 
standard.  There were no significant impacts to the consolidated statement of operations and consolidated statement of cash flows.

In August 2015, the FASB issued ASU No. 2015-14, “Revenue from Contracts with Customers (Topic 606) – Deferral of the 
Effective Date,” which revises the effective date of ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606),” (“ASU 
2014-09”) to interim and annual periods beginning after December 15, 2017, with early adoption permitted no earlier than interim and 
annual  periods  beginning  after  December  15,  2016.    In  May  2014,  the  FASB  issued  ASU  2014-09,  which  amends  current  revenue 
guidance.  The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or 
services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods 
or services.  The Company’s analysis of sales contracts under ASC 606 supports the recognition of revenue at a point in time, typically 
when title passes to the customer upon delivery, for the majority of contracts, which is consistent with the current revenue recognition 
model.  The Company utilized the modified retrospective approach, which requires a cumulative adjustment to retained earnings and 
no adjustments to prior periods.  The Company adopted this guidance as of January 1, 2018.  There was no material impact on the 
Company’s consolidated financial statements or disclosures.

Bauxite raw materials are used in the production of heavyweight ceramic products.  As of December 31, 2018 and 2017, the 
Company has classified as long-term assets those bauxite raw materials inventories that are not expected to be consumed in production 
during the upcoming twelve month period.  For additional information, refer to Note 5 – Other Operating (Income) Expense.  Other 
assets as of December 31, 2017 includes a $4,000 receivable relating to additional money owed us relating to the sale of our Russian 
proppant business.  This receivable was settled for $3,650 during 2018 and we recognized an additional loss on the sale of $350.  For 
additional information, refer to Note 18 – Sale of Russian Proppant Business.

Long-Term Debt and Notes Payable

On March 2, 2017, the Company entered into an Amended and Restated Credit Agreement (the “New Credit Agreement”) with 
Wilks Brothers, LLC (“Wilks”) to replace its term loan with Wells Fargo Bank, National Association (“Wells Fargo”) and provide the 
Company  with  additional  liquidity  for  a  longer  term.  The  New  Credit  Agreement  is  a  $65,000  facility  maturing  on  December  31, 
2022, that consists of a $52,651 term loan that was made at closing to pay off Wells Fargo and an additional term loan of $12,349 that 
was  made  to  the  Company  after  the  Company  satisfied  certain  post-closing  conditions.  The  $52,651  term  loan  was  a  non-cash 
transaction to the Company as Wilks directly paid Wells Fargo and assumed the New Credit Agreement.  The Company’s obligations 
bear  interest  at  9.00%  and  are  guaranteed  by  its  two  operating  subsidiaries.  No  principal  repayments  are  required  until  maturity 
(except in certain circumstances), and there are no financial covenants.

The  loan  cannot  be  prepaid  during  the  first  three  years  without  making  the  lenders  whole  for  interest  that  would  have  been 
payable over the entire remaining term of the loan.  The Company’s obligations under the New Credit Agreement are secured by: (i) a 
pledge of all accounts receivable and inventory, (ii) cash in certain accounts, (iii) domestic distribution assets residing on owned real 
property,  (iv)  the  Company’s  Marshfield,  Wisconsin  and  Toomsboro,  Georgia  plant  facilities  and  equipment,  and  (v)  certain  real 
property interests in mines and minerals.  Other liens previously in favor of Wells Fargo were released.  

As of December 31, 2018, the Company’s outstanding debt under its New Credit Agreement was $65,000.  Within 270 days of 

completion of all post-closing matters relating to the sale of our Millen, Georgia plant, the Company is required to use 100% of the 
Net Cash Proceeds (as defined in the New Credit Agreement) from the sale to either (1) prepay the outstanding principal amount of 
the Term Loans or (2) reinvest in fixed or capital assets of any Credit Party.  The Company is currently evaluating these options, and 
the Company may engage in negotiations with its lenders with respect to other options.  As of December 31, 2018, the Company has 
classified $15,733 of the outstanding debt as current liabilities, which represents an estimate of the Net Cash Proceeds that the 
Company would be required to prepay if it did not reinvest in fixed or capital assets.  See Note 19 for details on the sale of our Millen, 
Georgia plant.

As of December 31, 2018, the Company had $683 of unamortized debt issuance costs relating to the New Credit Agreement 
that  are  presented  as  a  direct  reduction  from  the  carrying  amount  of  the  long-term  debt  obligation.  The  Company  had  $2,625  and 
$9,230 in standby letters of credit issued through its banks as of December 31, 2018 and 2017, respectively, primarily as collateral 
relating to railcar leases for December 31, 2018 and our natural gas commitments and railcar leases for December 31, 2017.

On March 2, 2017, in connection with entry into the New Credit Agreement, the Company issued a Warrant (the “Warrant”) to 
Wilks.  Subject to the terms of the Warrant, the Warrant entitles the holder thereof to purchase up to 523,022 shares of the Common 
Stock, at an exercise price of $14.91 per share, payable in cash.  The Warrant expires on December 31, 2022.   Based on a Form 4 
filing  with  the  SEC  on  December  29,  2017,  as  of  December  31,  2018,  Wilks  owned  approximately  11.2%  of  the  Company’s 
outstanding  common  stock,  and  should  Wilks  fully  exercise  the  Warrant  to  purchase  an  additional  523,022  shares,  it  would  hold 
approximately  12.8%  of  the  Company’s  outstanding  common  stock.  Upon  issuance  of  the  Warrant,  the  Company  recorded  an 
increase to additional paid-in capital of $3,871.  As of December 31, 2018, the unamortized original issue discount was $2,934.

In  May  2016,  the  Company  received  proceeds  of  $25,000  from  the  issuance  of  separate  unsecured  Promissory  Notes  (the 
“Notes”) to two of the Company’s Directors.  Each Note matures on April 1, 2019 and bears interest at 7.00%.  On March 2, 2017, in 
connection  with  the  New  Credit  Agreement,  the  Notes  were  amended  to  provide  for  payment-in-kind,  or  PIK,  interest  payments  at 
8.00% until the lenders under the New Credit Agreement receive two consecutive semi-annual cash interest payments.  On April 1, 
2017, the Company made a $997 interest payment as PIK, and capitalized the resulting amount to the outstanding principal balance.  
On October 1, 2017, the Company made a $1,043 interest payment as PIK, and capitalized the resulting amount to the outstanding 
principal balance.  As of December 31, 2018, the outstanding principal balance of the Notes of $27,040 was recorded within current 
liabilities based on the April 1, 2019 maturity date.

Interest  cost  for  the  years  ended  December 31,  2018  and  2017  was  $8,612  and  $8,058,  respectively.  Interest  cost  primarily 
includes  interest  expense  relating  to  the  Company’s  debts  as  well  as  amortization  and  the  write-off  of  debt  issuance  costs  and 
amortization of the original issue discount associated with the New Credit Agreement and Warrant.

Other Operating (Income) Expense

Other operating income for the year ended December 31, 2018 primarily consisted of gains on asset sales, including one of the 
Company’s  distribution  centers,  and  was  partially  offset  by  other  operating  expenses.    Other  operating  expense  for  the  year  ended 
December 31, 2017 was primarily related to an impairment related to the Company’s Millen, Georgia plant. 

As of September 30, 2017, the Company had concluded that the Company’s Toomsboro and Millen, Georgia facilities should 
no longer be evaluated together as a group of assets because the facilities are no longer interchangeable and will not manufacture like 
products.  

Given the change in the asset groupings of the two facilities and lack of estimated future cash flows associated with the base 
ceramic  production  at  the  Millen  facility,  the  Company  identified  indicators  of  impairment  at  the  Millen,  Georgia  facility  as  of 
September  30,  2017.  The  Company  determined  that  the  projected  cash  flows  attributable  to  the  Millen,  Georgia  facility  did  not 
exceed  the  carrying  value  of  the  assets;  therefore  the  Company  concluded  there  was  an  impairment  at  that  facility.  The  Company 
engaged  the  services  of  a  third  party  consulting  firm  to  assist  with  the  determination  of  the  fair  value  of  the  related  assets,  which 
concluded  that  the  assets  were  impaired.  The  key  assumptions  and  inputs  impacting  the  fair  value  include  third  party  data  and 
commentary  with  respect  to  the  property  and  equipment  at  our  Millen  facility.  For  machinery  and  equipment  and  construction  in 
progress, we used a cost approach to estimate the valuation.  We applied a 65 percent downward adjustment to calculated replacement 
cost based on an analysis of construction documents and historical expenditures to remove non-saleable soft costs such as engineering 
and  installation  that  would  have  no  value  to  a  market  participant.  Based  on  discussions  with  market  participants,  a  salvage  value 
multiplier ranging from 12 percent to 50 percent of the remaining replacement cost basis was applied to arrive at the estimated fair 
value for the machinery and equipment and construction in progress subject to impairment.  For real property, we used a market and 
cost approach and reconciled the two approaches.  In using the market approach, we determined that the value of comparable property 
ranged  from  approximately  $30  to  $40  per  square  foot,  and  the  concluded  value  of  the  property  at  the  Millen  facility  was 
approximately $35 per square foot.  In using the cost approach, we applied a 94% downward adjustment to the calculated value for the 
buildings  and  site  improvements  as  a  representation  of  economic  obsolescence.    As  a  result  of  these  valuation  procedures,  which 
included  the  use  of  Level  3  inputs  as  defined  in  Note  10,  the  Company  recognized  a  $125,759  impairment  of  long-lived  assets, 
primarily relating to buildings, machinery and equipment, and construction in progress.  As of September 30, 2017, the fair value of 
the Millen facility was estimated to be $18,756 using Level 3 inputs as defined in Note 10.  The Millen facility was sold in December 
2018 for $23,000.  At the time of the sale, the Millen facility was classified as held for sale with a recorded value of $17,842.  See 
Note 19 for additional information.

As a result of the sale of the Company’s Millen facility for less than the carrying value of each of its Toomsboro Georgia and 
Eufaula,  Alabama  facilities  combined  with  the  continued  lowered  demand  for  our  base  ceramic  proppants,  the  Company  evaluated 
those long-lived assets for possible impairment as of December 31, 2018.  We prepared an undiscounted cash flow analysis for these 
two asset groups.  The Eufaula, Alabama facility is part of our technology asset group which also includes our New Iberia, Louisiana 
facility,  and  as  such,  we  evaluated  the  entire  technology  asset  grouping  for  impairment.    Key  assumptions  underlying  our 
undiscounted cash flow analysis included, but were not limited to, facility utilization, production costs, major maintenance and long-
term sales prices for products produced.  Based on these analyses, we noted that, for each of these asset groups, the carrying value was 
below the sum of the undiscounted cash flows, and thus no impairment was required.

If  there  are  changes  to  our  material  assumptions,  it  is  possible  that  we  may  have  to  recognize  impairments  in  the  future.  
However,  we  believe  that  the  material  assumptions  used  in  our  impairment  analysis  were  reasonable  and  were  based  on  available 
information and forecasts at the time.  We continue to monitor whether or not events or circumstances would indicate that the carrying 
value of any of our long-lived assets might not be recoverable.

The Company assesses goodwill for possible impairment annually or sooner if circumstances indicate possible impairment may 

have occurred.  There were no such impairments during 2018 or 2017.

Leases

The Company leases certain property, plant and equipment under operating leases, primarily consisting of railroad equipment 
leases.  Net minimum future rental payments due under non-cancelable operating leases with remaining terms in excess of one year as 
of December 31, 2018 are as follows:

2019 ...............................................................................................  $
2020 ...............................................................................................

Leases  of  railroad  equipment  generally  provide  for  renewal  options  at  their  fair  rental  value  at  the  time  of  renewal.    In  the 
normal course of business, operating leases for railroad equipment are generally renewed or replaced by other leases.  However, we 
expect to reduce our fleet of railcars as our current railcar leases expire.  Rent expense for all operating leases was $16,936 in 2018 
and $20,310 in 2017.   For the years ended December 31, 2018 and 2017, rent expense was stated net of sublease income of $4,142 
and $3,040, respectively.

As  a  result  of  the  significant  decline  in  oil  and  gas  activities  and  net  losses  incurred  over  the  past  few  years,  the  Company 
determined during the year ended December 31, 2017 that it was more likely than not that a portion of its deferred tax assets will not 
be realized in the future.  Accordingly, the Company established a $72,380 valuation allowance against its deferred tax assets as of 
December 31, 2018.  The Company’s assessment of the realizability of its deferred tax assets is based on the weight of all available 
evidence, both positive and negative, including future reversals of deferred tax liabilities.  

In December 2017, the Tax Cuts and Jobs Act (“Tax Legislation”) was enacted.  The Tax Legislation significantly revises the 
U.S. corporate income tax by, among other things, lowering corporate income tax rates, implementing the territorial tax system and 
imposing  a  repatriation  tax  on  deemed  repatriated  earnings  of  foreign  subsidiaries.    In  accordance  with  the  Tax  Legislation,  the 
Company recorded $28,163 as additional income tax expense in the fourth quarter of 2017 related to the re-measurement of deferred 
tax assets and liabilities.  Additionally, Staff Accounting Bulletin No. 118 ("SAB 118") was issued to address the application of U.S. 
GAAP  in  situations  when  a  registrant  does  not  have  the  necessary  information  available,  prepared,  or  analyzed  (including 
computations) in reasonable detail to complete the accounting for certain income tax effects of the Act.  December 22, 2018 marked 
the end of the measurement period for purposes of SAB 118.  As such, the Company has completed the analysis based on legislative 
updates  relating  to  the  Tax  Legislation.    No  material  changes  to  the  provisional  amounts  recorded  as  of  December  31,  2017  were 
identified.  

While the Tax Legislation provides for a territorial tax system, beginning in 2018, it includes the global intangible low-taxed 
income (“GILTI”) provision.  The GILTI provisions require the Company to include in its U.S. income tax return foreign subsidiary 
earnings  in  excess  of  an  allowable  return  on  the  foreign  subsidiary’s  tangible  assets.    FASB  guidance  indicates  that  accounting  for 
GILTI either as part of deferred taxes or as a period cost are both acceptable methods.  As of December 31, 2018, the Company has 
not  recognized  foreign  earnings  subject  to  GILTI.    An  accounting  policy  will  be  elected  in  the  first  period  in  which  the  GILTI 
provision becomes applicable to the Company.

During the years ended December 31, 2018 and 2017, the Company did not recognize benefits on foreign investments due to the 
uncertainty of the Company being able to realize the foreign tax assets in light of current market conditions in China and Russia.  This 
treatment decreased income tax benefit by $271 and $8,569 for the years ended December 31, 2018 and 2017, respectively.

During  2015  through  2018,  the  Company  incurred  net  operating  losses  in  the  United  States.    Net  operating  losses  associated 
with the 2015 tax return have been carried back in full, while certain of the net operating losses incurred in 2016, 2017, and 2018 are 
carried forward to offset future taxable income. The cumulative recorded tax benefit of these net operating loss carryforwards totals 
$88,341  and  $59,536  as  of  December  31,  2018  and  2017,  respectively,  and  is  included  in  the  deferred  income  tax  asset  on  those 
respective dates.  Theses recorded tax benefits include the impact of the change in corporate income tax rate following the enactment 
of the Tax Legislation.  After finalization of the 2015 Federal return and a change in the attribute of the NOL carryback, additional 
refunds for 2012 through 2014 tax years are being claimed in the amount of $2,107.  These amounts are included within income tax 
receivable as of December 31, 2018 and 2017.  The federal NOLs generated in 2017 and 2016 will be carried forward until they are 
utilized or their expiration in 2037 and 2036, respectively.  The federal NOLs generated in 2018 will be carried forward until they are 
utilized  as  they  do  not  expire  per  the  Tax  Cuts  and  Jobs  Act.    The  Company  has  not  recognized  any  uncertain  tax  positions  as  of 
December 31, 2018.

The Company files its tax returns as prescribed by the tax laws of the jurisdictions in which it operates, the most significant of 
which  are  U.S.  federal  and  certain  state  jurisdictions.    In  2016,  the  Company  received  an  audit  notice  from  the  Internal  Revenue 

F-16

 
 
 
 
 
 
 
 
 
 
 
 
 
 
  
  
  
  
  
  
  
  
 
Service for periods 2013-2015.  The Company does not anticipate any material findings.  The 2016 federal tax year is also subject to 
examination.    Various  U.S.  state  jurisdiction  tax  years  remain  open  to  examination  as  well,  although  the  Company  believes 
assessments, if any, would be immaterial to its consolidated financial statements.

Shareholders’ Equity

Common Stock

Holders  of  Common  Stock  are  entitled  to  one  vote  per  share  on  all  matters  to  be  voted  on  by  shareholders  and  do  not  have 
cumulative voting rights.  Subject to preferences of any Preferred Stock, the holders of Common Stock are entitled to receive ratably 
such dividends, if any, as may be declared from time to time by the Board of Directors out of funds legally available for that purpose.  
The Company does not expect to pay dividends in the foreseeable future.  In the event of liquidation, dissolution or winding up of the 
Company, holders of Common Stock are entitled to share ratably in all assets remaining after payment of liabilities, subject to prior 
distribution  rights  of  any  Preferred  Stock  then  outstanding.    The  Common  Stock  has  no  preemptive  or  conversion  rights  or  other 
subscription rights.  There are no redemption or sinking fund provisions applicable to the Common Stock.  All outstanding shares of 
Common Stock are fully paid and non-assessable.

Preferred Stock

The Company’s charter authorizes 5,000 shares of Preferred Stock.  The Board of Directors has the authority to issue Preferred 
Stock in one or more series and to fix the rights, preferences, privileges and restrictions thereof, including dividend rights, conversion 
rights, voting rights, terms of redemption, redemption prices, liquidation preferences and the number of shares constituting any series 
or the designation of such series, without further vote or action by the Company’s shareholders.

Equity Offering Program

On  July  28,  2016,  the  Company  filed  a  prospectus  supplement  and  associated  sales  agreement  related  to  an  at-the-market 
(“ATM”)  equity  offering  program  pursuant  to  which  the  Company  may  sell,  from  time  to  time,  common  stock  with  an  aggregate 
offering price of up to $75,000 through Cowen and Company LLC, as sales agent, for general corporate purposes.  During the year 
ended December 31, 2018, the Company sold a total of 300,227 shares of its common stock under the ATM program for $2,914, or an 
average of $9.71 per share, and received proceeds of $2,849, net of commissions of $65.  As of December 31, 2018, the Company had 
sold  a  total  of  3,705,936  shares  of  its  common  stock  under  the  ATM  program  for  $49,527,  or  an  average  of  $13.36  per  share,  and 
received proceeds of $48,412, net of commissions of $1,114.

Natural Gas Derivative Instruments

Natural gas is used to fire the kilns at the Company’s manufacturing plants.  In an effort to mitigate volatility in the cost of natural 
gas purchases and reduce exposure to short term spikes in the price of this commodity, we contracted in advance for portions of our future 
natural  gas  requirements.   Due  to  the  severe  decline  in  industry  activity  beginning  in  early  2015,  we  significantly  reduced  production 
levels and consequently did not take delivery of all of the contracted natural gas quantities.  As a result, we had accounted for the relevant 
contracts as derivative instruments.  However, as of December 31, 2018, our last derivative contract expired and no future natural gas 
obligations existed.

The  Company  used  the  income  approach  in  determining  the  fair  value  of  these  derivative  instruments.    The  model  used 
considers  the  difference,  as  of  each  balance  sheet  date,  between  the  contracted  prices  and  the  New  York  Mercantile  Exchange 
(“NYMEX”) forward strip price for each contracted period.  The estimated cash flows from these contracts were discounted using a 
discount rate of 8.0%, which reflects the nature of the contracts as well as the timing and risk of estimated cash flows associated with 
the contracts.  The discount rate had an immaterial impact on the fair value of the contracts for the year ended December 31, 2017.  
During the year ended December 31, 2018 and 2017, the Company recognized a gain on derivative instruments of $1,195 and a loss 
on derivative instruments of $917, respectively, in cost of sales.  The cumulative present value of the natural gas derivative contracts 
as of December 31, 2017 were classified as current liabilities in the Consolidated Balance Sheet.  As a result of the expiration of the 
last natural gas contract on December 31, 2018, there is no remaining liability as of December 31, 2018.

10. Fair Value Measurements

The  Company’s  derivative  instruments  are  measured  at  fair  value  on  a  recurring  basis.    U.S.  GAAP  establishes  a  fair  value 
hierarchy that has three levels based on the reliability of the inputs used to determine the fair value.  These levels include: Level 1, 
defined as inputs such as unadjusted quoted prices in active markets for identical assets or liabilities; Level 2, defined as inputs other 

F-17

than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs for 
use when little or no market data exists, therefore requiring an entity to develop its own assumptions.

The  Company’s  natural  gas  derivative  instruments  are  included  within  the  Level  2  fair  value  hierarchy.    For  additional 
information on the derivative instruments, refer to Note 9 – Natural Gas Derivative Instruments.  The following table sets forth by 
level within the fair value hierarchy the Company’s assets and liabilities that were accounted for at fair value:

Stock Based Compensation

On  May  20,  2014,  the  shareholders  approved  the  2014  CARBO  Ceramics  Inc.  Omnibus  Incentive  Plan  (the  “2014  Omnibus 
Incentive  Plan”).    The  2014  Omnibus  Incentive  Plan  replaces  the  expired  2009  Omnibus  Incentive  Plan.    In  May  2017,  the 
shareholders  approved  the  Amended  and  Restated  2014  CARBO  Ceramics  Inc.  Omnibus  Incentive  Plan  (the  “Amended  2014 
Omnibus Plan”).  Under the Amended 2014 Omnibus Incentive Plan, the Company may grant cash-based awards, stock options (both 
non-qualified  and  incentive)  and  other  equity-based  awards  (including  stock  appreciation  rights,  phantom  stock,  restricted  stock, 
restricted  stock  units,  performance  shares,  deferred  share  units  or  share-denominated  performance  units)  to  employees  and  non-
employee directors.  The amount paid under the Amended 2014 Omnibus Incentive Plan to any single participant in any calendar year 
with  respect  to  any  cash-based  award  shall  not  exceed  $5,000.    Awards  may  be  granted  with  respect  to  a  number  of  shares  of  the 
Company’s Common Stock that in the aggregate does not exceed 1,450,000 shares prior to the fifth anniversary of its effective date, 
plus  (i)  the  number  of  shares  that  are  forfeited,  cancelled  or  returned  and  (ii)  the  number  of  shares  that  are  withheld  from  the 
participants to satisfy an option exercise price or minimum statutory tax withholding obligations.  No more than 100,000 shares may 
be granted to any single participant in any calendar year.  Equity-based awards may be subject to performance-based and/or service-
based  conditions.    With  respect  to  stock  options  and  stock  appreciation  rights  granted,  the  exercise  price  shall  not  be  less  than  the 
market value of the underlying Common Stock on the date of grant.  The maximum term of an option is ten years.  Restricted stock 
awards granted generally vest (i.e., transfer and forfeiture restrictions on these shares are lifted) proportionately on each of the first 
three anniversaries of the grant date, but subject to certain limitations, awards may specify other vesting periods.  As of December 31, 
2018, 481,883 shares were available for issuance under the Amended 2014 Omnibus Incentive Plan.

A summary of restricted stock activity and related information for the year ended December 31, 2018 is presented below:

As of December 31, 2018, there was $3,644 of total unrecognized compensation cost related to restricted shares granted under 
Amended and Restated 2014 Omnibus Incentive Plan.  That cost is expected to be recognized over a weighted-average period of 1.6 
years.  The weighted-average grant date fair value of restricted stock granted during the years ended December 31, 2018 and 2017 was

$12.16 and $10.30, respectively.  The total fair value of shares vested during the years ended December 31, 2018 and 2017 was $1,567 
and $2,023, respectively.

As of December 31, 2018, the Company’s outstanding market-based cash awards to certain executives of the Company had a 
total Target Award of $3,034.  The amount of awards that will ultimately vest can range from 0% to 200% based on the Company’s 
Relative Total Shareholder Return calculated over a three year period beginning January 1 of the year each grant was made.  During 
the year ended December 31, 2018, a total of $526 was paid relating to the 2015 grant, which was approximately 76% of the target 
award.  We expect to pay $708 in 2019 relating to the 2016 grant, which is approximately 61% of the target award.

The Company also made phantom stock awards to key employees pursuant to the Amended 2014 Omnibus Incentive Plan.  The 
units subject to an award vest and cease to be forfeitable in equal annual installments over a three-year period.  Participants awarded 
units of phantom stock are entitled to a lump sum cash payment equal to the fair market value of a share of Common Stock on the 
vesting date.  In no event will Common Stock of the Company be issued with regard to outstanding phantom stock awards.  As of 
December 31, 2018, there were 214,616 units of phantom stock granted under the Amended 2014 Omnibus Incentive Plan, of which 
54,020 have vested and 23,511 have been forfeited.  As of December 31, 2018, nonvested units of phantom stock under the Amended 
2014  Omnibus  Incentive  Plan  have  a  total  value  of  $477,  a  portion  of  which  is  accrued  as  a  liability  within  Accrued  Payroll  and 
Benefits.

12. Loss Per Share

ASC Topic 260, “Earnings Per Share”, provides that unvested share-based payment awards that contain non-forfeitable rights 
to dividends or dividend equivalents (whether paid or unpaid) are participating securities and shall be included in the computation of 
earnings per share pursuant to the two-class method.  The Company’s outstanding non-vested restricted stock awards are participating 
securities.    Accordingly,  earnings  per  common  share  are  computed  using  the  two-class  method.    The  impact  of  the  Company’s 
Warrant issued to Wilks in March 2017 was not included in the computation of diluted loss per share because the average price for our 
common stock was less than the strike price of the Warrant and, therefore, the Warrant was not dilutive for 2018 or 2017. The Warrant 
entitles the holder thereof to purchase up to 523,022 shares of the Common Stock, at an exercise price of $14.91 per share, payable in 
cash.  Refer to Note 4.   

The following table sets forth the computation of basic and diluted loss per share under the two-class method:

Segment Information

The  Company  has  two  operating  segments:  1)  Oilfield  and  Industrial  Technologies  and  Services  and  2)  Environmental 
Technologies  and  Services.  Discrete  financial  information  is  available  for  each  operating  segment.  Management  of  each  operating 
segment  reports  to  our  Chief  Executive  Officer,  the  Company’s  chief  operating  decision  maker,  who  regularly  evaluates  income 
before  income  taxes  as  the  measure  to  evaluate  segment  performance  and  to  allocate  resources.  The  accounting  policies  of  each 
segment are the same as those described in the summary of significant accounting policies in Note 1.

The  Company’s  Oilfield  and  Industrial  Technologies  and  Services  segment  manufactures  and  sells  technology  ceramic 
products and services, base ceramic proppant and frac sand for both the oilfield and industrial sectors.  These products have different 
technology  features  and  product  characteristics,  which  vary  based  on  the  application  for  which  they  are  intended  to  be  used.  The 
various ceramic products’ manufacturing processes are similar.

Oilfield  ceramic  technology  products,  base  ceramic  proppant  and  frac  sand  proppant  are  manufactured  and  sold  to  pressure 
pumping  companies  and  oil  and  gas  operators  for  use  in  the  hydraulic  fracturing  of  natural  gas  and  oil  wells.    This  segment  also 
promotes  increased  production  and  Estimated  Ultimate  Recovery  (“EUR”)  of  oil  and  natural  gas  by  providing  industry-leading 
technology to Design, Build, and Optimize the Frac®.  Through our wholly-owned subsidiary StrataGen, Inc., we sell one of the most 
widely  used  fracture  stimulation  software  under  the  brand  FracPro and  provide  fracture  design  and  consulting  services  to  oil  and 
natural gas E&P companies under the brand StrataGen.

Our  industrial  ceramic  technology  products  are  manufactured  at  the  same  facilities  and  using  the  same  machinery  and 
equipment  as  the  oilfield  products,  however  they  are  sold  to  industrial  companies.  These  products  are  designed  for  use  in  various 
industrial technology  applications,  including,  but  not  limited  to,  casting  and  milling.  Our  chief  operating  decision  maker  reviews 
discreet financial information as a whole for all of our manufacturing, consulting and software businesses.  Manufacturing includes the 
manufacture of technology products, base ceramics, industrial ceramics, sand and contract manufacturing, regardless of the industry 
the products are ultimately sold to.  See Note 2 for disaggregated revenue information.

Our  Environmental  Technologies  and  Services  segment  designs,  manufactures  and  sells  products  and  services  intended  to 
protect  operators’  assets,  minimize  environmental  risks,  and  lower  lease  operating  expense  (“LOE”).  AGPI,  a  wholly-owned 
subsidiary  of  ours,  provides  spill  prevention,  containment  and  countermeasure  systems  for  the  oil  and  gas  industry.  AGPI  uses 
proprietary  technology  designed  to  enable  its  clients  to  extend  the  life  of  their  storage  assets,  reduce  the  potential  for  hydrocarbon 
spills and provide containment of stored materials.

16. Commitments 

The  Company  has  an  agreement  with  a  supplier  to  purchase  at  least  50  percent  of  the  annual  kaolin  requirements  for  the 
Eufaula, Alabama plant at specified contract prices.  In May 2017, the agreement was extended for an additional three years.  For the 
years ended December 31, 2018 and 2017, the Company purchased from the supplier $1,141 and $2,207, respectively, of kaolin under 
the agreement.

The Company has a mining agreement with a contractor to purchase 100% percent of the annual kaolin requirements for the 
Company’s McIntyre and Toomsboro, Georgia plants at specified contract prices, from lands owned or leased by either the Company 
or the contractor.  The agreement remains in effect until such time as all Company-owned minerals have been depleted.  For the years 
ended December 31, 2018 and 2017, the Company purchased $2,161 and $950, respectively, of kaolin under the agreement.

The  Company  had  an  agreement  with  a  supplier  to  provide  frac  sand  for  the  Company’s  Marshfield,  Wisconsin  plant  at  a 
specified contract price.  The terms of the agreement required the Company to purchase minimum annual amounts and remained in 
effect until the specified sand was depleted.  For the years ended December 31, 2018 and 2017, the Company purchased $2,452 and 
$3,837, respectively, of frac sand under this agreement.  The mine was depleted in 2018 and there are no future commitments under 
this agreement.

The  Company  has  an  agreement  with  a  supplier  to  purchase  wet  sand  at  specified  contract  prices.    The  two-year  agreement 
began January 1, 2018 and requires the Company to purchase 720,000 tons over the two-year contract.  Any shortfall would be due 
from the Company at two dollars per ton.  As of December 31, 2018, there was approximately 435,000 remaining to be purchased 
under the agreement.  For the year ended December 31, 2018, the Company purchased $4,586 of wet sand under this agreement.  In 
addition, the Company has an agreement with a sand processing company to process sand at specified prices.  The two year agreement 
also  began  January  1,  2018  and  requires  the  Company  to  process  at  least  10,000  tons  per  month  on  a  rolling  three-month  average.  
Any shortfall would be due from the Company at seven dollars per ton.    The Company provided an upfront capital infusion to the 
sand  processing  company  to  facilitate  the  processing  of  wet  sand  and  will  be  repaid  to  the  Company  as  an  offset  to  future  sand 
processing charges.  As of December 31, 2018, the total amount due to the Company relating to the unrecovered capital infusion and 
other  receivables  was  approximately  $716,  which  is  recorded  within  prepaid  expenses  and  other  current  assets.  For  the  year  ended 
December 31, 2018, the Company spent $2,369 in net sand processing charges under this agreement.

The Company had an agreement with a supplier to provide hydro sized sand for the Company’s Marshfield, Wisconsin plant at a 
specified contract price.  The Company agreed to purchase a minimum of 40,000 tons with the option to purchase additional hydro 
sized sand at the Company’s discretion.  As of December 31, 2018, the Company purchased $1,077 of hydro sized sand under this 
agreement.  As of December 31, 2017, the Company had not yet purchased any hydro sized sand under this agreement.  There are no 
further commitments under this agreement.

The Company entered into a lease agreement dated November 1, 2008 (“2008 Agreement”) with the Development Authority of 
Wilkinson  County  (the  “Wilkinson  County  Development  Authority”).    Pursuant  to  the  2008  Agreement,  the  Wilkinson  County 
Development Authority holds the title to the real and personal property of the Company's McIntyre and Toomsboro manufacturing 
facilities and leases the facilities to the Company for an annual administrative fee of $50 per year. The Company elected the renewal 
option on November 1, 2017, which extended the lease through November 1, 2021.  At any time prior to the scheduled termination of 
the lease, the Company has the option to terminate the lease and purchase the property for a nominal fee plus the payment of any rent 
payable through the balance of the lease term.  Furthermore, the Company has security interests in the titles held by the Development 

F-22

 
 
 
 
 
 
   
      
  
 
Authority.  The Company has also entered into a Memorandum of Understanding (the “MOU”) with the Development Authority and 
other local agencies, under which the Company receives tax incentives in exchange for its commitment to invest in the county and 
increase employment.  The Company is required to achieve certain employment levels in order to retain its tax incentives.  In the event 
the  Company  does  not  meet  the  agreed-upon  employment  targets  or  the  MOU  is  otherwise  terminated,  the  Company  would  be 
subjected to additional property taxes annually.  Based on adverse economic conditions beyond the Company’s control that negatively 
impacted  employment  levels,  a  notice  dated  February  1,  2016  sent  by  the  Company  to  the  Development  Authority  of  Wilkinson 
County declared a force majeure, which suspended employment levels defined in the original agreement and preserved tax incentives 
until further notification of the restart of plant operations.  The Development Authority of Wilkinson County has not challenged the 
Company’s declaring a force majeure.  The properties subject to these lease agreements are included in Property, Plant and Equipment 
(net book value of $104,179 at December 31, 2018) in the accompanying consolidated financial statements.

17. Employment Agreements

The Company has an employment agreement through December 31, 2019 with its President and Chief Executive Officer.  The 
agreement provides for an annual base salary and incentive bonus.  If the President and Chief Executive Officer is terminated early 
without cause, the Company will be obligated to pay two years base salary and a prorated incentive bonus.  Under the agreement, the 
timing  of  the  payment  of  severance  obligations  to  the  President  in  the  event  of  the  termination  of  his  employment  under  certain 
circumstances  has  been  conformed  so  that  a  portion  of  such  obligations  will  be  payable  in  a  lump  sum,  with  the  remainder  of  the 
obligations to be paid over an 18 month period.  The agreement also contains a two-year non-competition covenant that would become 
effective upon termination for any reason.  The employment agreement extends automatically for successive one-year periods without 
prior written notice.

Sale of Russian Proppant Business

On  July  21,  2017,  subsidiaries  of  the  Company  Carbo  Ceramics  (Mauritius)  Inc.  and  Carbo  LLC  (together,  the  “Sellers”) 
entered  into  a  Share  Purchase  Agreement  with  Petro  Welt  Technologies  AG  and  PeWeTe  Evolution  Limited  (together,  the 
“Purchasers”) to sell the Company’s Russian proppant business.  The adjusted purchase price was approximately $26,000 for all of the 
shares  of  CARBO  Ceramics  Cyprus  Limited  held  by  the  Sellers.  The  transaction  received  local  regulatory  approval  and  closed  on 
September 21, 2017.

The net assets included in the calculation of the loss on the sale were $17,754, including cash and cash equivalents of $846, 
accounts  receivable  of  $6,047,  total  inventory  of  $8,573,  net  PP&E  of  $2,763,  other  net  assets  of  $670,  and  accrued  expenses  of 
$1,145.  The Company incurred approximately $1,646 in expenses relating to the sale.  Gain on the sale before consideration of the 
cumulative translation adjustment was approximately $6,599.  However, as a result of the sale, the Company reclassified the foreign 
currency cumulative translation loss of $33,347 from accumulated other comprehensive loss within shareholders’ equity to net loss 
which offset the initial gain on the sale.  As a result, the Company’s net loss on the sale was approximately $26,747, presented as a 
separate line item within operating loss on the consolidated statement of operations.

As  of  December  31,  2017,  the  Company  was  owed  $4,000  related  to  net  debt  and  net  working  capital  purchase  price 
adjustments.    In  January  2018,  the  Company  filed  a  Notice  of  Arbitration  related  to  this  purchase  price  adjustment  against  the 
Purchasers.    During  the  second  quarter  of  2018,  the  Company  settled  the  dispute  with  the  Purchasers.  Terms  of  the  settlement 
required the Purchasers to pay $3,650, and as a result we recorded a loss of $350.  In July 2018, we received the settlement proceeds 
of approximately $3,650, which is included within investing cash flows on the consolidated statement of cash flows for the year ended 
December 31, 2018.

As of December 31, 2018, the Company does not have a material net investment that is subject to foreign currency fluctuations. 

19.

Sale of Millen Facility

On December 31, 2018, the Company entered into a Purchase and Sale Agreement with a Buyer to sell the Company’s ceramic 
proppant  manufacturing  facility  in  Millen,  Georgia  for  $23,000.    The  transaction  closed  on  December  31,  2018.    Selling  expenses, 
including certain post-closing matters and retained liabilities, totaled approximately $7,267.  As of December 31, 2018, the Company 
had paid approximately $899 of the total selling expenses.  As such, net proceeds of $22,101 is included within investing cash flows 
on the consolidated statement of cash flows for the year ended December 31, 2018.  The selling expenses that had not yet been paid as 
of  December  31,  2018  primarily  relate  to  the  post-closing  matters  and  retained  liabilities,  and  are  recorded  as  liabilities  as  of 
December 31, 2018 within other accrued expenses, other current liabilities and other long-term liabilities on the consolidated balance 
sheets.    The  payment  of  the  post-closing  matters  will  be  an  investing  cash  outflow  when  paid,  and  the  repayment  of  the  retained 
liabilities  will  be  financing  outflows  when  repaid  over  a  multi-year  period.    Net  Cash  Proceeds,  as  defined  in  the  New  Credit 

F-23

Agreement, is expected to approximate $15,733, calculated as the gross proceeds of $23,000 less the selling expenses of $7,267.  See 
Note  4.    The  retained  liabilities,  due  to  the  City  of  Millen  and  the  local  electrical  cooperative,  are  associated  with  their  respective 
investments in the Millen facility’s electrical and natural gas infrastructure during the construction of the plant.  The Company also 
retained an existing liability associated with a long-term fixed natural gas transportation agreement.  These retained liabilities, totaling 
approximately  $4,852,  will  be  repaid  over  a  multi-year  period  and  are  included  in  other  current  liabilities  and  other  long-term 
liabilities.  As of December 31, 2018, the fair value of these retained liabilities approximated the carrying value.  Subsequent to the 
balance sheet date, the Company executed a note payable with the local electrical cooperative for its share of the retained liabilities 
with a principal balance equal to the liability recorded at December 31, 2018.  The note bears interest at 5% annually and requires 
monthly principal and interest payments of $35 until maturity in February 2024.  In order to backstop the amounts due under these 
retained liabilities, the Company agreed to an escrow holdback of $3,000 at closing and provided a letter of credit for an additional 
$2,000.    The  letter  of  credit  will  be  reduced  by  $400  each  year  until  maturity.    The  Company  also  agreed  to  a  separate  escrow 
holdback of $1,200 pending completion of the post-closing matters.  The book value of the assets held for sale was $17,842, which 
after consideration of the selling price, the write-off of certain spare parts totaling $196 and costs to sell the facility, resulted in a loss 
on the sale of $2,305. 

20. Legal Proceedings and Regulatory Matters

The  Company  is  subject  to  legal  proceedings,  claims  and  litigation  arising  in  the  ordinary  course  of  business.    While  the 
outcome of these matters is currently not determinable, management does not expect that the ultimate costs to resolve these matters 
will have a material adverse effect on the Company’s consolidated financial position, results of operations, or cash flows.

21.

Subsequent Events

In January 2019, the Company awarded the following:

468,984  shares  of  restricted  stock  to  certain  employees.    The  fair  value  of  the  stock  award  on  the  date  of  grant  totaled 
$2,298, which will be recognized as expense, less actual forfeitures as they occur, on a straight-line basis over the three-year 
vesting period.

105,276 units of phantom shares to certain employees.  The fair value of the phantom shares on the date of grant totaled 
$516.    Compensation  expense  for  these  shares  will  be  recognized  over  the  three-year  vesting  period.    The  amount  of 
compensation expense recognized each period will be based on the fair value of the Company’s common stock at the end of 
each period.
