ITEM 1.  BUSINES
S.

General.

PART I

United States Lime & Minerals, Inc. (the “Company,” the “Registrant,” “We” or “Our”), which was incorporated in 1950, conducts
its business primarily through its Lime and Limestone Operations segment.  During 2019, our natural gas interests did not reach any of the
quantitative thresholds for a reportable segment, and we do not expect the results from our natural gas interests to be of significance in
future periods.  The revenues, gross profit and operating profit from our natural gas interests are included in Other for our reportable
segment disclosures.  Disclosures  for 2018 and 2017 have been recast to be consistent with the 2019 presentation.

The Company’s principal corporate office is located at 5429 LBJ Freeway, Suite 230, Dallas, Texas 75240. The Company’s

telephone number is (972) 991-8400 and its internet address is www.uslm.com. The Company’s annual reports on Form 10-K, quarterly
reports on Form 10-Q, current reports on Form 8-K and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of
the Securities Exchange Act of 1934, as amended (the “Exchange Act”), as well as the Company’s definitive proxy statement filed pursuant
to Section 14(a) of the Exchange Act, are available free of charge on the Company’s website as soon as reasonably practicable after the
Company electronically files such material with, or furnishes it to, the Securities and Exchange Commission (the “SEC”).

Lime and Limestone Operations.

Business and Products.  The Company, through its Lime and Limestone Operations, is a manufacturer of lime and limestone

products, supplying primarily the construction (including highway, road and building contractors), industrial (including paper and glass
manufacturers), environmental (including municipal sanitation and water treatment facilities and flue gas treatment processes), metals
(including steel producers), oil and gas services, roof shingle manufacturers and agriculture (including poultry and cattle feed producers)
industries. The Company is headquartered in Dallas, Texas and operates lime and limestone plants and distribution facilities in Arkansas,
Colorado, Louisiana, Oklahoma and Texas through its wholly owned subsidiaries, Arkansas Lime Company, Colorado Lime Company,
Texas Lime Company, U.S. Lime Company, U.S. Lime Company—Shreveport, U.S. Lime Company—St. Clair and U.S. Lime Company—
Transportation.

The Company extracts high-quality limestone from its open-pit quarries and an underground mine and then processes it for sale as
pulverized limestone, quicklime, hydrated lime and lime slurry. Pulverized limestone (also referred to as ground calcium carbonate) (“PLS”) is
produced by applying heat to dry the limestone, which is then ground to granular and finer sizes. Quicklime (calcium oxide) is produced by
heating limestone to very high temperatures in kilns in a process called calcination. Hydrated lime (calcium hydroxide) is produced by
reacting quicklime with water in a controlled process. Lime slurry (milk of lime) is a suspended solution of calcium hydroxide produced by
mixing quicklime with water in a lime slaker.

PLS is used in the production of construction materials such as roof shingles and asphalt paving, as an additive to agriculture

feeds, in the production of glass, as a soil enhancement, in flue gas treatment for utilities and other industries requiring scrubbing of
emissions for environmental purposes and for mine safety dust in coal mining operations. Quicklime is used primarily in metal processing, in
flue gas treatment, in soil stabilization for highway, road and building construction, as well as for oilfield roads and drill sites, in the
manufacturing of paper products and in municipal sanitation and water treatment facilities. Hydrated lime is used primarily in municipal
sanitation and water treatment facilities, in soil stabilization for highway, road and building construction, in flue gas treatment, in asphalt as
an anti-stripping agent, as a conditioning agent for oil and gas drilling mud, and in the production of chemicals. Lime slurry is used primarily
in soil stabilization for highway, road and building construction.

Product Sales.  In 2019, the Company sold almost all of its lime and limestone products in the states of Arkansas, Arizona,
Colorado, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Mississippi, Missouri, New Mexico, Oklahoma, Tennessee and Texas.  Sales
were made primarily by the Company’s nine sales employees who call on current and potential customers and solicit orders, which are
generally made on a purchase-order basis. The Company also receives orders in response to bids that it prepares and submits to current
and potential customers.

Table of Contents

Principal customers for the Company’s lime and limestone products are construction customers (including highway, road and

building contractors), industrial customers (including paper manufacturers and glass manufacturers), environmental customers (including
municipal sanitation and water treatment facilities and flue gas treatment processes), metals producers (including steel producers), oil and
gas services companies, roof shingle manufacturers and poultry and cattle feed producers. During 2019, the strongest demand for the
Company’s lime and limestone products was from construction customers, industrial customers, environmental customers, metals
producers, oil and gas services companies and roof shingle manufacturers.

Approximately 600 customers accounted for the Company’s sales of lime and limestone products during 2019. No single customer

accounted for more than 10% of such sales. The Company is generally not subject to significant customer demand and credit risks as its
customers are considerably diversified as to geographic location and industry concentration. However, given the nature of the lime and
limestone industry, the Company’s profits are very sensitive to changes in sales volume and prices.

Lime and limestone products are transported by truck and rail to customers generally within a radius of 400 miles of each of the

Company’s plants. All of the Company’s 2019 sales were made within the United States.

Order Backlog.  The Company does not believe that backlog information accurately reflects anticipated annual revenues or

profitability from year to year.

Seasonality.  The Company’s sales have typically reflected seasonal trends, with the largest percentage of total annual shipments
and revenues normally being realized in the second and third quarters. Lower seasonal demand normally results in reduced shipments and
revenues in the first and fourth quarters. Inclement weather conditions generally have a negative impact on the demand for lime and
limestone products supplied to construction-related customers, as well as on the Company’s open-pit quarrying operations.

Limestone Reserves.  The Company’s limestone reserves contain at least 96% calcium carbonate (CaCO3). The Company has two
subsidiaries that extract limestone from open-pit quarries: Texas Lime Company (“Texas Lime”), which is located near Cleburne, Texas, and
Arkansas Lime Company (“Arkansas Lime”), which is located near Batesville, Arkansas. U.S. Lime Company—St. Clair (“St. Clair”) extracts
limestone from an underground mine located near Marble City, Oklahoma. Colorado Lime Company (“Colorado Lime”) owns property
containing limestone deposits at Monarch Pass, Colorado. Existing crushed stone stockpiles on the property are being used to provide
feedstock to the Company’s plant in Delta, Colorado. Access to all properties is provided by paved roads and, in the case of Arkansas Lime
and St. Clair, also by rail.

Texas Lime operates a quarry and has lime, hydrated lime and limestone production facilities, located on approximately 4,100 acres
of land that contains known high-quality limestone reserves in a bed averaging 28 feet in thickness, with an overburden that ranges from 0
to 50 feet. Texas Lime also has mineral interests in approximately 330 acres of land adjacent to the northwest boundary of its property. The
Texas Lime reserves, as of December 31, 2019, were approximately 29 million tons of proven recoverable reserves plus approximately 78
million tons of probable recoverable reserves. Assuming the current level of production and recovery rate is maintained, the Company
estimates that these reserves are sufficient to sustain operations for more than 70 years.

Arkansas Lime operates two quarries and has lime, hydrated lime and limestone production facilities on a second site linked to the
quarries by its own railroad. The quarries cover approximately 1,050 acres of land located in Independence County, Arkansas containing a
known deposit of high-quality limestone reserves (the “Batesville Quarry”). The average thickness of the high-quality limestone bed is
approximately 60 feet, with an average overburden thickness of approximately 30 feet. The reserves for the Batesville Quarry, as of
December 31, 2019, were approximately 7 million tons of proven recoverable reserves.  In 2005, the Company acquired approximately 2,500
acres of land in nearby Izard County, Arkansas (the “Love Hollow Quarry”). The high-quality reserves on these 2,500 acres, as of
December 31, 2019, were approximately 76 million tons of probable recoverable reserves. The Company continues to assess opportunities to
improve the transportation infrastructure between the Love Hollow Quarry and Arkansas Lime’s production facilities and other
development costs to prepare the Love Hollow Quarry for mining. Assuming the current level of production and recovery rate is
maintained, the Company estimates that its total reserves in Arkansas are sufficient to sustain operations for more than 60 years.

Table of Contents

St. Clair operates an underground mine and has lime, hydrated lime and limestone production facilities located on approximately
1,400 acres that it owns containing high-quality limestone reserves. The reserves, as of December 31, 2019, were approximately 12 million
tons of probable recoverable reserves on 410 acres. Assuming the current level of production and recovery rate is maintained, the Company
estimates that the probable recoverable reserves are sufficient to sustain operations for approximately 25 years. In addition, St. Clair also
has the right to mine the high-quality limestone contained in approximately 1,330 adjacent acres pursuant to long-term mineral leases. The
Company has not conducted a drilling program to identify and categorize reserves on the 1,330 leased acres.

During 2019, the Company produced approximately 3 million tons of limestone from its quarries and mine.

Colorado Lime acquired the Monarch Pass Quarry in November 1995 and has not carried out any mining on the property. A review

of the potential limestone resources has been completed by independent geologists; however, the Company has not initiated a drilling
program. Consequently, it is not possible to identify and categorize reserves. The Monarch Pass Quarry, which had been operated for many
years until the early 1990s, contains a mixture of limestone types, including high-quality calcium limestone and dolomite. Assuming the
current level of production is maintained, the Company estimates that the remaining crushed stone stockpiles on the property are sufficient
to supply its Delta, Colorado plant for approximately 15 years.

Quarrying and Mining.  The Company extracts limestone by the open-pit method at its Texas and Batesville quarries. The
Monarch Pass Quarry is also an open-pit quarry but is not being mined at this time. The open-pit method consists of removing any
overburden comprising soil and other substances, including inferior limestone, and then extracting the exposed high-quality limestone. The
Company removes such overburden by utilizing both its own employees and equipment and those of outside contractors. Open-pit mining
is generally less expensive than underground mining. The principal disadvantage of the open-pit method is that operations are subject to
inclement weather and overburden removal. The limestone is extracted by drilling and blasting, utilizing standard mining equipment. At its
St. Clair underground mine, the Company mines limestone using room and pillar mining.  We have no knowledge of any recent changes in
the physical quarrying or mining conditions on any of our properties that have materially affected quarrying or mining operations.

Plants and Facilities.  After extraction, limestone is crushed and screened and, in the case of PLS, ground and dried, or, in the case
of quicklime, processed in kilns. Quicklime may then be further processed in hydrators and slakers to produce hydrated lime and lime slurry.
The Company processes and distributes lime and/or limestone products at four plants, six lime slurry facilities and three terminal facilities.
All of its plants and facilities are accessible by paved roads, and, in the case of the Arkansas Lime and St. Clair plants and the terminal
facilities, also by rail.

The Texas Lime plant has an annual capacity of approximately 470 thousand tons of quicklime from two preheater rotary kilns. The
plant also has PLS equipment, which, depending on the product mix, has the capacity to produce approximately 800 thousand tons of PLS
annually.

The Arkansas plant is situated at the Batesville Quarry. Utilizing three preheater rotary kilns, this plant has an annual capacity of

approximately 630 thousand tons of quicklime. Arkansas Lime’s PLS and hydrating facilities are situated on a tract of 290 acres located
approximately two miles from the Quarry, to which it is connected by a Company-owned railroad. The PLS equipment, depending on the
product mix, has the capacity to produce approximately 300 thousand tons of PLS annually.

After we brought the new vertical kiln into production at St. Clair in the second quarter 2019 and removed from service the older,

non-preheater rotary kiln, the St. Clair plant has an annual capacity of approximately 250 thousand tons of quicklime from one preheater
rotary kiln and one vertical kiln. The plant also has PLS equipment, which has the capacity to produce approximately 150 thousand tons of
PLS annually.

The Company also maintains lime hydrating and bagging equipment at the Texas, Arkansas and St. Clair plants. Storage facilities

for lime and limestone products at each plant consist primarily of cylindrical tanks, which are considered by the Company to be adequate to
protect its lime and limestone products and to provide an available supply for customers’ needs at the expected volumes of shipments.
Equipment is maintained at each plant to load trucks and, at the Arkansas Lime and St. Clair plants, to load railroad cars.

Colorado Lime operates a limestone grinding and bagging facility with an annual capacity of approximately 125 thousand tons,

located on approximately three and one-half acres of land in Delta, Colorado.

During 2019, the Company’s utilization rate was approximately 64% of its aggregate annual production capacity for the plants in its

Lime and Limestone Operations.

U.S. Lime Company (“US Lime”) uses quicklime to produce lime slurry and has four Houston area facilities, including two
distribution terminals connected to railroads, to serve the Greater Houston area construction market and four facilities to serve the Dallas-
Ft. Worth Metroplex. The Company established U.S. Lime Company—Transportation (“Transportation”) to deliver some of the Company’s
products to its customers and facilities primarily in the Dallas-Ft. Worth Metroplex.  In December 2017, Transportation sold its trucks in
Houston, Texas for approximately their net book value and entered into a dedicated transportation services agreement with a third-party
carrier to deliver the Company’s products to its customers and slurry facilities in the Houston metropolitan area.

U.S. Lime Company — Shreveport operates a distribution terminal in Shreveport, Louisiana, which is connected to a railroad, to

provide lime storage, hydrating, slurrying and distribution capacity to service markets in Louisiana and East Texas.

The Company believes that its plants and facilities are adequately maintained and insured.

Employees.  At December 31, 2019, the Company employed 282 persons and is a party to two collective bargaining agreements.

The collective bargaining agreement for the Texas facilities expires in November 2020.  The collective bargaining agreement for the
Arkansas facilities expires in January 2023. Overall, the Company believes that its employee relations are good.

Competition.  The lime industry is highly regionalized and competitive, with price, quality, ability to meet customer demands and

specifications, proximity to customers, personal relationships and timeliness of deliveries being the prime competitive factors. The
Company’s competitors are predominantly private companies.

The lime industry is characterized by high barriers to entry, including: the scarcity of high-quality limestone deposits on which the

required zoning and permitting for extraction can be obtained; the need for lime plants and facilities to be located close to markets, paved
roads and railroad networks to enable cost-effective production and distribution; clean air and anti-pollution regulations, including those
related to greenhouse gas emissions, which make it more difficult to obtain permitting for new sources of emissions, such as lime kilns; and
the high capital cost of the plants and facilities. These considerations reinforce the premium value of operations having permitted, long-
term, high-quality limestone reserves and good locations and transportation relative to markets.

Lime producers tend to be concentrated on known high-quality limestone formations where competition takes place principally on

a regional basis.  While the steel industry and environmental-related users, including utility plants, are the largest market sectors, the lime
industry also counts chemical users and other industrial users, including paper manufacturers, oil and gas services and highway, road and
building contractors, among its major customers. 

In recent years, the lime industry has experienced reduced demand from certain industries as they experience cyclical or secular
downturns.  For example, demand from the Company’s steel and oil and gas services customers tends to vary with the demand for their
products and services, which has continued to be cyclical.  In addition, utility plants are continuing to use more natural gas and renewable
sources for power generation instead of coal, which reduces their demand for lime and limestone for flue gas treatment processes.  These
reductions in demand have resulted in increased competitive pressures, including pricing and competition for certain customer accounts, in
the industry. 

Consolidation in the lime industry has left the three largest companies accounting for more than two-thirds of North American

production capacity. In addition to the consolidations, and often in conjunction with them, many lime producers have undergone
modernization and expansion and development projects to upgrade their processing equipment in an effort to improve operating efficiency. 
We believe that our modernization and expansion projects in Texas and Arkansas and the recent kiln project at our St. Clair operations in
Oklahoma, along with our lime slurry operations in Texas, should allow us to continue to remain competitive, protect our markets and
position ourselves for the future. In addition, we will continue to evaluate internal and external opportunities for expansion, growth and

4

Table of Contents

increased profitability, as conditions warrant, or opportunities arise. We may have to revise our strategy or otherwise consider ways to
enhance the value of the Company, including by entering into strategic partnerships, mergers or other transactions.

Impact of Environmental Laws.  The Company owns or controls large areas of land on which it operates limestone quarries, an
underground mine, lime plants and other facilities with inherent environmental responsibilities, compliance costs and liabilities.  These
include maintenance and operating costs for pollution control equipment, the cost of ongoing monitoring programs, the cost of reclamation
efforts and other similar environmental costs and liabilities. 

The Company’s operations are subject to various federal, state and local laws and regulations relating to the environment, health
and safety and other regulatory matters, including the Clean Air Act, the Clean Water Act, the Resource Conservation and Recovery Act,
the Comprehensive Environmental Response, Compensation and Liability Act and analogous state and local laws (“Environmental
Laws”).  These Environmental Laws grant the United States Environmental Protection Agency (the “EPA”) and state governmental
agencies the authority to promulgate and enforce regulations that could result in substantial expenditures on pollution control, waste
management, permitting and compliance activities. Many Environmental Laws also authorize private citizens and interest groups to file
lawsuits in court to enforce alleged violations.  The failure to comply with Environmental Laws may result in administrative and civil
penalties, injunctive relief and criminal prosecution.  The Company has not been named as a potentially responsible party in any federal
superfund cleanup site or state-led cleanup site. 

The rate of change of Environmental Laws continues to be rapid, and compliance can require significant expenditures.  For
example, the Clean Air Act required the Company’s lime plants to obtain Title V operating permits that have significant ongoing compliance
costs.  In addition to the Title V permits, other environmental operating permits are required for the Company’s operations, and such
permits are subject to modification during the permit renewal process and, in rare instances, could be revoked. 

Over time, the EPA has increased the stringency of the National Ambient Air Quality Standards (“NAAQS”) under the Clean Air

Act.

The EPA has lowered ozone standards and reclassified areas where State Implementation Plans (the “SIPs”) exist.  In October

2015, the EPA issued a final rule lowering the ground-level ozone NAAQS to 70 parts per billion.  In December 2018, the EPA issued a final
rule affecting SIP requirements for attainment demonstrations, planning and implementation deadlines for reasonably available control
technology, emissions inventories and emissions standards, and the timing of required SIP revisions.  State environmental agencies in the
states in which we operate are currently in the process of revising their SIPs to comply.  For example, the Texas Commission on
Environmental Quality issued a proposed rule package in November 2019 to incorporate the 2015 ozone NAAQS into the Texas SIP.  This
and similar rulemakings could increase the cost of future plant modifications or expansions, increase compliance costs and have a material
adverse effect on the Company’s financial condition, results of operations, cash flows and competitive position.    

EPA regulations require large emitters of greenhouse gases, including the Company’s plants, to collect and report greenhouse gas

emissions data.  The EPA has previously indicated that it will use the data collected through the greenhouse gas reporting rules to decide
whether to promulgate future greenhouse gas emission limits. The EPA and delegated states also regulate greenhouse gas emissions under
the New Source Review permitting and Federal Operating Permit programs for facilities that are otherwise subject to permitting based on
their emissions of conventional, non-greenhouse gas pollutants. Thus, any new facilities or major modifications to existing facilities that
exceed the federal New Source Review emission thresholds for conventional pollutants may be required to use “best available control
technology” and energy efficiency measures to minimize greenhouse gas emissions.

Although the timing and impact of climate change legislation and of regulations limiting greenhouse gas emissions are uncertain,
the consequences of such legislation and regulation are potentially significant for the Company because the production of CO2 is inherent
in the manufacture of lime through the calcination of limestone and combustion of fossil fuels.  Future greenhouse gas rulemaking could
affect New Source Review permitting and, thereby, increase the time and costs of plant upgrades and expansions.  The passage of climate
change legislation, and other regulatory initiatives by the Congress, the states or the EPA that restrict or tax emissions of greenhouse
gases, could also adversely affect the Company.  There is no assurance that changes in the law or regulations will not be adopted, such as
the imposition of a carbon tax, a cap-and-trade program requiring the Company to purchase carbon credits or other measures that would
require reductions in emissions or changes to raw materials, fuel use or production rates.  Such

5

 
 
 
Table of Contents

changes, if adopted, could have a material adverse effect on the Company’s financial condition, results of operations, cash flows and
competitive position.

In addition to regulation, several court cases have been filed and decisions issued that may increase the risk of claims being filed

by third parties against companies for their greenhouse gas emissions.  Such cases may seek to challenge air permits, to force reductions in
greenhouse gas emissions or to recover damages for alleged climate change impacts to the environment, people and property.

The lime industry is currently undergoing a revision to a federal regulation that establishes national standards to meet the
maximum achievable control technology (“MACT”) within the industry.  Also known as the “Lime MACT,” this rulemaking is the second
revision to the initial Lime MACT promulgated in 2004.  The EPA published its proposed revision to the Lime MACT in September 2019 and
the final rule is expected to be published in 2020.  The proposal included changes to the startup, shutdown and malfunction provisions
contained in the current Lime MACT rule, but otherwise did not impose more stringent standards. A non-governmental organization
submitted opposing comments arguing that the lime industry should be subject to all unregulated hazardous air pollutants. The pulp and
paper industry is currently under litigation before the D.C. Circuit Court of Appeals.  In that litigation, a non-governmental organization has
argued that the EPA was required to issue standards for unregulated hazardous air pollutants in MACT rulemaking.  These arguments are
not industry-specific and, depending on the outcome of the case, could be applied to other industries, including the lime industry.

In addition to litigation risk, policy changes or changes in political leadership could affect the Lime MACT rulemaking. There is no

assurance that the final Lime MACT rule will adopt the approach in the proposed rule, and the final Lime MACT could incorporate more
stringent standards.  Depending on the outcome of the pulp and paper industry litigation, the rulemaking process could take 1-2 years
before any new EPA standards would take effect, or the final Lime MACT rule could be published and effective in 2020.  Changes in the
Lime MACT could have a material adverse effect on the Company’s financial condition, results of operations, cash flows and competitive
position.

The Company also holds permits for process water and storm water discharges.  Any failure to comply with these permits could

result in fines or other penalties.  Material changes to the terms of these permits in the future could also increase compliance costs. 

The manufacturing of lime and hydrated lime requires significant volumes of fresh water.  The Company operates multiple
groundwater wells to provide water to its plants.  Groundwater pumping is subject to increased regulation, and in some areas the Company
is required to obtain permits from groundwater conservation districts in order to pump groundwater.  Any failure to comply with these
permits could result in fines or other penalties. 

The Company incurred capital expenditures related to environmental matters of $1.2 million, $1.2 million and $0.4 million in 2019,
2018 and 2017, respectively. The Company’s recurring costs associated with managing environmental permitting and waste recycling and
disposal (e.g., used oil and lubricants) and maintaining pollution control equipment amounted to $0.5 million, $0.6 million and $0.7 million in
2019, 2018 and 2017, respectively.

The Company recognizes legal reclamation and remediation obligations associated with the retirement of long-lived assets at their
fair value at the time the obligations are incurred (“Asset Retirement Obligations” or “AROs”). Over time, the liability for AROs is recorded
at its present value each period through accretion expense, and the capitalized cost is amortized over the useful life of the related asset.
Upon settlement of the liability, the Company either settles the ARO for its recorded amount or recognizes a gain or loss. AROs are
estimated based on studies and the Company’s process knowledge and estimates and are discounted using an appropriate interest rate.
The AROs are adjusted when further information warrants an adjustment. The Company believes its accrual of $1.5 million for AROs at
December 31, 2019 is reasonable.

Other.

Our Other operations are conducted through our wholly owned subsidiary, U.S. Lime Company – O&G, LLC (“U.S. Lime – O&G”)

and consist principally of a lease with respect to oil and gas rights on our Cleburne, Texas property, located in the Barnett Shale
Formation.  Pursuant to the lease, we have royalty interests ranging from 15.4% to 20% in oil and gas produced from any successful wells
drilled on the leased property and an option to participate in any well drilled on the leased property as a 20% non-operated working interest
owner.  At December 31, 2019, our overall average interest under the oil and gas rights lease was 34.7% on 33 producing wells.

U.S. Lime – O&G has also entered into a drillsite agreement with an operator that has an oil and gas lease covering approximately

538 acres of land contiguous to our Johnson County, Texas property.  Pursuant to the drillsite agreement, we have a 3% royalty interest
and a 12.5% non-operated working interest.  At December 31, 2019, we had a combined 12.4% royalty and non-operated working interest on
6 active wells drilled on a padsite located on our Johnson County, Texas property.

No new wells have been completed since 2011, and there are no plans to drill additional wells under either the oil and gas lease or
the drillsite agreement.  During 2019, our natural gas interests did not reach any of the quantitative thresholds for a reportable segment, and
we do not expect the results from our natural gas interests to be of significance in future periods.

ITEM 1A.  RISK FACTOR
S.

Our Lime and Limestone Operations are affected by general economic and regulatory conditions in the U.S. and specific

economic and regulatory conditions in particular industries.

General and industry specific economic conditions in the United States have reduced demand for our lime and limestone
products.  Specifically, demand from our utility customers has decreased due to the continuing trend in the United States to retire coal-fired
utility plants.  In the past, our steel and oil and gas services customers have reduced their purchase volumes, at times, due to cyclical
economic conditions in their industries.  The overall reduction in demand for lime and limestone products has also resulted in increased
competitive pressures, including pricing pressure and competition for certain customer accounts, from other lime producers. 

We are also in a period of regulatory uncertainty. While various actions and proposals by the current Administration and

Congress to reduce regulations in certain respects or as to certain industries, to increase infrastructure spending, to permit increased oil
and gas drilling, to increase the use of coal, to stimulate steel and other manufacturing and to protect U.S. markets, as well as the impact of
corporate tax reforms, may increase U.S. economic activity and the demand for our lime and limestone products, there can be no assurance
that such results will be achieved or that they will benefit us or our customers. In addition, depending on the outcome and effects of such
proposals, a variety of factors, including uncertainty with respect to governmental budgetary constraints, legislative impasses, extended
government shutdowns, pandemics, trade wars, tariffs and increased inflationary pressures, could have a material adverse effect on our
financial condition, results of operations, cash flows and competitive position that, on balance, may offset some or all of the benefits to us
and our customers from the otherwise favorable regulatory changes.

For us to maintain or increase our profitability, we must maintain or increase our revenues and improve cash flows, manage our

capital expenditures and control our operational and selling, general and administrative expenses. If we are unable to maintain our revenues
and control our costs in these uncertain economic and regulatory times, our financial condition, results of operations, cash flows and
competitive position could be materially adversely affected.

In the normal course of our Lime and Limestone Operations, we face various business and financial risks that could have a

material adverse effect on our financial position, results of operations, cash flows and competitive position. Not all risks are
foreseeable or within our ability to control.

These risks arise from various factors, including, but not limited to, fluctuating demand and prices for our lime and limestone

products, including as a result of downturns in the economy and in the construction, industrial, steel and oil and gas services industries,
and reduced demand from coal-fired utility plants, increased competitive pressures from other lime producers, changes in legislation and
regulations, including Environmental Laws, health and safety regulations and requirements to renew or obtain operating permits, our ability
to produce and store quantities of lime and limestone products sufficient in amount and quality to meet customer demands and
specifications, the success of our modernization, expansion and development strategies, the uncertainty of our ability to sell our increased
lime capacity from the new kiln at our St. Clair facility at acceptable prices, our ability to execute our strategies and complete projects on
time and within budget, our ability to integrate, refurbish and/or improve acquired facilities, our access to capital, volatile costs, especially
fuel, electricity, transportation and freight costs, inclement weather and the effects of seasonal trends.

We receive most of our coal and petroleum coke by rail, so the availability of sufficient solid fuels to run our plants could be

diminished significantly in the event of major rail disruptions. Domestic coal and petroleum coke may also be exported, which can increase
competition and prices for the domestic supply. In addition, our freight costs to deliver our lime and limestone products are high relative to
the value of our products, and they have generally increased in recent years. Our costs for delivery of solid fuels, as well as our products,
also increase as demand for rail and trucking by other industries increases, and revised Department of Transportation rules have reduced
the availability of trucks, truck drivers and rail cars to deliver solid fuels to our plants and deliver our products to our customers. If we are
unable to continue to pass along our variable coal, petroleum coke, diesel, natural gas, electricity, transportation and freight costs to our
customers through higher prices or surcharges, our financial condition, results of operations, cash flows and competitive position could be
materially adversely affected.

8

Table of Contents

We quote our lime and limestone products on a delivered price basis to certain customers, which requires us to estimate future

delivery costs. Our actual delivery costs may exceed these estimates, which would reduce our profitability.

Delivery costs are impacted by the price of diesel. When diesel prices increase, we incur additional fuel surcharges from freight
companies that cannot be passed on to our customers that have been quoted a delivered price. Material increases in the price of diesel
could have a material adverse effect on the Company’s profitability.

Governmental fiscal and budgetary constraints, legislative impasses, and extended government shutdowns have in the past,

and may in the future, adversely impact our financial condition and results of operations in various ways.

Governmental fiscal and budgetary constraints, legislative impasses and extended government shutdowns may adversely impact

our financial condition and results of operations in various ways, including possibly reduced highway construction and infrastructure
funding by federal, state and local governmental agencies, which could reduce demand for our lime and limestone products from our
construction customers.

Our mining and other operations are subject to operating risks that are beyond our control, which could result in materially

increased operating expenses and decreased production and shipment levels that could materially adversely affect our Lime and
Limestone Operations and their profitability.

We mine limestone in open pit and underground mining operations and process and distribute that limestone through our plants

and other facilities. Certain factors beyond our control could disrupt our operations, adversely affect production and shipments and
increase our operating costs, all of which could have a material adverse effect on our results of operations.  These include geological
formation problems that may cause poor mining conditions, variability of chemical or physical properties of our limestone, an accident or
other major incident at a site that may cause all or part of our operations to cease for some period of time and increase our expenses, mining,
processing and plant equipment failures and unexpected maintenance problems that may cause disruptions and added expenses, strikes,
job actions or other work stoppages that may disrupt our operations or those of our suppliers, contractors or customers and increase our
expenses, and adverse weather conditions and natural disasters, such as hurricanes, tornadoes, heavy rains, flooding, ice storms, freezing
weather, drought and other natural events, that may affect operations, transportation or customers.

If any of these conditions or events occurs, our operations may be disrupted, we could experience a delay or halt of production or
shipments, our operating costs could increase significantly, and we could be exposed to fines, penalties, assessments and other liabilities.
If our insurance coverage is limited or excludes a given condition or event, we may not be able to recover in full the losses that we may
incur as a result of such conditions or events, some of which may be substantial.

We incur environmental compliance costs and liabilities in our Lime and Limestone Operations, including capital,
maintenance and operating costs, with respect to pollution control equipment, the cost of ongoing monitoring programs, the cost of
reclamation and remediation efforts and other similar costs and liabilities relating to our compliance with Environmental Laws.  We
expect these costs and liabilities to continue or increase, including possible new costs, taxes and limitations on operations, including
regulation of greenhouse gas emissions.  Similar environmental costs and liabilities may also be faced by some of our customers.

The rate of change of Environmental Laws has been rapid over the last decade, and we may face possible new uncertainties, costs

and liabilities, taxes and limitations on operations, including those related to climate change initiatives.  Even with the current period of
regulatory uncertainty that could result in deregulation in certain areas, we expect our expenditure requirements for future environmental
compliance, including complying with nitrogen dioxide, sulfur dioxide, ozone and particulate matter emission limitations under the NAAQS
and regulation of greenhouse gas emissions, to continue or increase.  Discovery of currently unknown conditions and unforeseen costs
and liabilities could require additional expenditures. 

The regulation of greenhouse gas emissions remains an issue for the Company and some of its customers. There is no assurance

that changes in the law or regulations will not be adopted, such as the imposition of a carbon tax, a cap-

9

 
Table of Contents

and-trade program requiring companies to purchase carbon credits, or other measures that would require reductions in emissions or
changes to raw materials, fuel use or production rates.  These changes, if adopted, could have a material adverse effect on the Company’s
financial condition, results of operations, cash flows and competitive position. 

More stringent regulation of greenhouse gas emissions could also adversely affect the competitiveness of some of the Company’s

customers, including coal-fired power plants, and indirectly the demand for our lime and limestone products.  For example, our utility
customers are continuing to switch from coal to natural gas or renewable sources for power generation for environmental and regulatory as
well as cost reasons, thus reducing demand for our lime and limestone products for flue gas treatment processes.

We intend to comply with all Environmental Laws and believe our accrual for environmental costs and liabilities at December 31,
2019 is reasonable. Because many of the requirements are subjective and therefore not quantifiable or presently determinable, or may be
affected by additional legislation and rulemaking, including those related to climate change and greenhouse gas emissions, there is no
assurance that we will be able to successfully secure new permits in connection with our future modernization and expansion and
development projects, and it is not possible to accurately predict the aggregate future costs and liabilities relating to environmental
compliance and their effect on our financial condition, results of operations, cash flows and competitive position.

The lime and limestone industry is highly regionalized and competitive.

Our competitors are predominately large private companies. The primary competitive factors in the lime industry are price, quality,

ability to meet customer demands and specifications, proximity to customers, personal relationships and timeliness of deliveries, with
varying emphasis on these factors depending upon the specific product application. To the extent that one or more of our competitors
becomes more successful with respect to any key competitive factor, we may find it difficult to increase or maintain our prices or to retain
certain customer accounts, and our financial condition, results of operations, cash flows and competitive position could be materially
adversely affected.

To maintain our competitive position in the lime and limestone industry, we may need to continue to increase the efficiency of

our operations and expand production capacity, obtain financing for any such projects and acquisitions at reasonable interest rates
and acceptable terms and sell any resulting increased production at acceptable prices.

We may in the future undertake additional modernization and expansion and development projects and acquisitions. Such projects

and acquisitions may require that we incur substantial debt, which may not be available to us at all or at reasonable interest rates or on
acceptable terms. Given current and projected demand for lime and limestone products, we cannot guarantee that any such project or
acquisition would be successful, that we would be able to sell any resulting increased production at acceptable prices or that any such
sales would be profitable.

Although prices for our lime and limestone products have been relatively firm in past years, pricing competition has increased in

recent years. We are unable to predict future demand and prices, given the current economic and regulatory uncertainties in the U.S.
economy as a whole and in particular industries, and cannot provide any assurance that current levels of demand and prices will continue
or that any future increases in demand or prices can be maintained.

We may be adversely affected by any disruption in, or failure of, our information technology systems, including due to cyber-

security risks and incidents.

We rely upon the capacity, reliability and security of our information technology (“IT”) systems for our mining, manufacturing,
sales, financial and administrative functions. We also face the challenge of supporting our IT systems and implementing upgrades when
necessary, including the prompt detection and remediation of any cyber-security breaches.

Our IT systems security measures are focused on the prevention, detection and remediation of damage from computer viruses,
natural disasters, unauthorized access, cyber-attack and other similar disruptions. However, our IT systems protection measures may not
be successful in preventing unauthorized access, intrusion and damage. Threats to our systems can derive from human error, fraud or
malice on the part of employees or third parties or may result from

10

 
 
 
Table of Contents

technological failure.  Any failure, accident or security breach involving our IT systems could result in disruption to our operations. A
material breach in the security of our IT systems could negatively impact our mining and manufacturing operations, sales or financial and
administrative functions, or result in the compromise of personal information of our employees, customers or suppliers. To the extent any
such failure, accident or security breach results in disruption to our operations or sales or loss or disclosure of, or damage to, our data or
confidential information, our costs could increase, and our reputation, business, results of operations and financial condition could be
materially adversely affected. Additionally, should we experience a cyber-security event, we may incur substantial costs, including
remediation costs, such as liability for stolen assets or information, repairs of system damage, legal costs and costs associated with
regulatory actions.

ITEM 4.  MINE SAFETY DISCLOSURES.

Under Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 104 of Regulation S-K, each
operator of a coal or other mine is required to include disclosures regarding certain mine safety results in its periodic reports filed with the
SEC. The operation of the Company’s quarries, underground mine and plants is subject to regulation by the federal Mine Safety and Health
Administration (“MSHA”) under the Federal Mine Safety and Health Act of 1977. The required information regarding certain mining safety
and health matters, broken down by mining complex, for the year ended December 31, 2019  is presented in Exhibit 95.1 to this Report.

The Company believes it is responsible to employees to provide a safe and healthy workplace environment. The Company seeks
to accomplish this by: training employees in safe work practices; openly communicating with employees; following safety standards and
establishing and improving safe work practices; involving employees in safety processes; and recording, reporting and investigating
accidents, incidents and losses to avoid reoccurrence.

Following passage of the Mine Improvement and New Emergency Response Act of 2006, MSHA significantly increased the
enforcement of mining safety and health standards on all aspects of mining operations. There has also been an increase in the dollar
penalties assessed for citations and orders issued in recent years.

OVERVIEW.

General.

We have identified one reportable business segment based on the distinctness of our activities and products: Lime and Limestone

Operations. All operations are in the United States. Operating profit from our Lime and Limestone Operations includes all of our selling,
general and administrative costs. We do not allocate interest expense and interest and other income to our Lime and Limestone Operations.

Our Lime and Limestone Operations represent our principal business. Our Other revenues are from natural gas interests,
consisting of royalty and non-operated working interests under an oil and gas lease and a drillsite agreement with two separate operators
related to our Johnson County, Texas property, located in the Barnett Shale Formation, on which Texas Lime conducts its lime and
limestone operations. Our principal management decisions related to our natural gas interests involve whether to participate as a non-
operated working interest owner by contributing our proportional costs for drilling proposed wells or workovers of existing wells. While we
intend to continue to participate in future natural gas wells drilled and workovers of existing wells under the oil and gas lease and drillsite
agreement, if any, we are not in the business of drilling for or producing natural gas and have no personnel with expertise in that field.

During 2019, our natural gas interests did not reach any of the quantitative thresholds for a reportable segment, and we do not

expect the results from our natural gas interests to be of significance in future periods.  The revenues, gross profit and operating profit from
our natural gas interests are included in Other in our reportable segment disclosures.  Assets related to our natural gas interests,
unallocated corporate assets and cash items are included in Other identifiable assets.  Disclosures for 2018 and 2017 have been recast to be
consistent with the 2019 presentation.

Revenues increased 9.6% in 2019 compared to 2018.  Revenues from our Lime and Limestone Operations increased 10.6% in 2019,
compared to 2018, primarily due to increased sales volumes of 8.6% for our lime and limestone products in 2019, compared to 2018, and an
increase in average product prices for our lime and limestone

14

Table of Contents

products of 2.0%.  The 2019 increase in sales volumes resulted from increased demand, primarily from our construction and environmental
customers.  

Gross profit increased 36.7% in 2019 compared to 2018. Gross profit from our Lime and Limestone Operations in 2019 increased

42.6%, compared to 2018, primarily due to the increased revenues discussed above, lower fuel costs, and increased operating efficiencies
associated with our new, fuel-efficient kiln at our St. Clair facility, which began producing commercially salable quicklime in the second
quarter 2019.

In the fourth quarter 2019, we recognized an impairment charge of $0.9 million ($0.7 million, net of tax) to adjust the carrying values

of the long-lived assets related to our natural gas interests.  Prices for natural gas and natural gas liquids decreased substantially during
2019, compared to 2018, which led to the impairment of the assets.   

Interest expense remained flat at $0.2 million for each of 2019 and 2018.  Interest and other income, net, increased $0.1 million in
2019, or 4.9%, compared to 2018,  primarily due to increased interest rates received on our cash and cash equivalents balances in 2019.

Net income increased $6.4 million, or 32.4%, in 2019, compared to 2018.  Net income per fully diluted share increased to $4.64 in

2019, compared to $3.51 in 2018.

Our existing cash balances and cash flows from operations enabled us to make $27.1 million of capital investments and pay

$33.1 million in dividends, including a $30.0 million special cash dividend, in 2019. Our cash balances decreased to  $54.3 million at
December 31, 2019, compared to $67.2 million at December 31, 2018, principally reflecting payment of the special dividend in 2019.  At
December 31, 2019, we had no debt outstanding.

Our new kiln at St. Clair began producing commercially salable quicklime in the second quarter 2019, delivering increased

efficiencies in our production of quicklime.  Through December 31, 2019, we have spent $44.2 million on the kiln and the related
modernization project at St. Clair.  In 2020, we expect to complete certain upgrades and enhancements to equipment related to the new kiln
as part of the modernization project.  When fully completed, we anticipate the final cost of the project, including the kiln, will be
approximately $50 million.

During the fourth quarter 2019, we paid a special cash dividend of $30.0 million, or $5.35 per share, on our common stock, in

addition to our regular quarterly cash dividend of $0.135 (13.5 cents) per share.

On January 30,  2020, we announced that our Board of Directors had declared an increased regular quarterly cash dividend of $0.16

 (16 cents) per share.  The dividend is payable on March 13,  2020 to shareholders of record on February 21, 2020.

Absent a significant acquisition opportunity arising during 2020, we anticipate funding our operating and capital needs and

our increased quarterly cash dividend from our cash balances on hand and cash flows from operations.

Lime and Limestone Operations.

In our Lime and Limestone Operations, we produce and sell PLS, quicklime, hydrated lime and lime slurry. The principal factors

affecting our success are the level of demand and prices for our products and whether we are able to maintain sufficient production levels
and product quality while controlling costs.

Inclement weather conditions, such as winter ice and snow storms, cold weather, hurricanes, tornadoes and excessive rainfalls
generally reduce the demand for lime and limestone products supplied to construction-related customers that account for a significant
amount of our revenues. Inclement weather also interferes with our open-pit mining operations and can disrupt our plant production. In
addition to weather, various maintenance, environmental, accident and other operational and construction issues can also disrupt our
operations and increase our operating expenses.

Demand for our products in our market areas is also affected by general economic conditions, the pace of construction, the
demand for steel, the level of oil and gas drilling in our markets, the level of governmental and private funding for highway construction and
infrastructure and utility plant usage of coal for power generation. Demand for our lime and limestone products from our construction and
environmental customers increased in 2019. Favorable weather conditions in Texas positively impacted demand from our construction
customers in 2019, compared to 2018 when it

15

Table of Contents

was adversely impacted by sustained rains throughout the months of September and October, although Texas weather has begun 2020 with
above average rainfall.

In 2014 and 2015, Texas approved two constitutional amendments authorizing a portion of oil and gas tax revenues to be deposited

into the State Highway Fund, for certain other sales and use tax revenues to be directed to the State Highway Fund and, beginning in
Texas’ fiscal 2020, for certain state motor vehicle sales and rental tax revenues to be directed to the State Highway Fund.  With these State
funding improvements, along with the $200 billion federal spending on infrastructure investment proposed by the current Administration,
we would expect to see increases in demand from our construction customers, but the timing of any demand increase is uncertain and
subject to weather and other factors.  

Our modernization and expansion and development projects in Texas,  Arkansas, and Oklahoma and our Texas slurry operations
have positioned us to meet the demand for high-quality lime and limestone products in our markets. Our modernization and expansion and
development projects have also equipped us with up-to-date, fuel-efficient plant facilities, which have resulted in lower production costs
and greater operating efficiencies, thus enhancing our competitive position. All our rotary kilns are now fuel-efficient preheater kilns.  The
addition of the new kiln at St. Clair further increased the fuel efficiency of our fleet of kilns.

For our plants to operate at peak efficiency, we must meet operational challenges that arise from time to time, including bringing
new facilities on-line and refurbishing and/or improving acquired facilities, as well as operating existing facilities efficiently. We also incur
ongoing costs for maintenance and to remain in compliance with rapidly changing Environmental Laws and health and safety and other
regulations.

Our primary variable cost is energy. Prices for coal, petroleum coke, diesel, natural gas, electricity, transportation and freight are

volatile. In addition, our freight costs, including diesel prices, to deliver our products can be high relative to the value of our products. We
have been able to mitigate to some degree the adverse impact of volatile energy costs by varying the mixes of fuel used in our kilns, and by
passing on some of any increase in costs onto our customers, where possible, through higher prices and/or surcharges on certain
products.  In addition, as noted above, we recently put a new, more fuel-efficient kiln in service at St. Clair, which should help us better
manage our energy costs at that plant.  Finally, we have not engaged in any significant hedging activity in an effort to control our energy
costs but may do so in the future.

We have financed our modernization and expansion and development projects and acquisitions through a combination of debt
financing, which has now been repaid, and cash flows from operations. We must generate sufficient cash flows to cover ongoing capital
requirements, including current and possible future modernization and expansion and development projects and acquisitions, or borrow
sufficient funds to finance any shortfall in our liquidity needs.

For us to maintain or increase our profitability in our Lime and Limestone Operations in the face of reduced demand from some of

our customers, competitive pressures and increased costs, we must maintain or increase our customer base, improve our revenues and
control our operational and selling, general and administrative expenses. To maintain or improve our gross profit margins, we are focusing
on maintaining, and increasing where possible, our lime and limestone prices to offset our increased costs, which is a challenging task with
increased competition from other lime and limestone producers. In addition, we will continue to explore ways to increase the operating
efficiency of our plants and other facilities and expand our production capacity through acquisitions as conditions warrant or opportunities
arise.

We continue to believe the enhanced efficiency and production capacity resulting from our modernization and expansion and

development projects at Texas,  Arkansas, and Oklahoma, our expanded slurry operations, our acquisitions and the operational strategies
we have implemented have allowed us to increase our efficiency, grow production capacity, improve product quality, better serve existing
customers, attract new customers and control costs. To date, however, demand and prices for our lime and limestone products have not
been sufficient to fully utilize our additional production capacity.  In addition, there can be no assurance that our efficiency and production
will not be adversely affected by weather, maintenance, environmental, accident, cyber-security, and other operational and construction
issues; that we can successfully invest in improvements to our existing facilities; that our results will not be adversely affected by increases
in fuel, natural gas, electricity, transportation and freight costs or new environmental, health and safety or

16

Table of Contents

other regulatory requirements; or that, with increasing competition with other lime and limestone producers, our revenues, gross profit, net
income and cash flows can be maintained or improved.

Other.

Revenues in 2019 included $1.3 million from our natural gas interests, compared to $2.5 million and $2.2 million in 2018 and 2017,

respectively.   Gross profit (loss) in 2019 included a loss of $(0.4) million from our natural gas interests, compared to profit of $1.0 million and
$0.7 million in 2018 and 2017, respectively. 

CRITICAL ACCOUNTING POLICIES.

The discussion and analysis of our financial condition and results of operations are based upon our consolidated financial
statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America
(“US GAAP”). The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts
of assets, liabilities, revenues and expenses, and related disclosures of contingent assets and liabilities, at the date of our financial
statements. Actual results may differ from these estimates and judgments under different assumptions or conditions and historical trends.

Critical accounting policies are defined as those that are reflective of significant management judgments and uncertainties and
potentially result in materially different results under different assumptions and conditions. We believe the following critical accounting
policies require the most significant management estimates and judgments used in the preparation of our consolidated financial statements.

Revenue recognition.  We recognize revenue for our Lime and Limestone Operations when (i) a contract with the customer exists
and the performance obligations are identified, (ii) the price has been established; and (iii) the performance obligations have been satisfied,
which is generally upon shipment.  Revenues include external freight billed to customers with related costs accounted for as fulfillment
costs and included in cost of revenues.  Our returns and allowances are minimal.  External freight billed to customers included in revenues
was $28.3 million, $25.6 million and $23.5 million for 2019, 2018 and 2017, respectively, which approximates the amount of external freight
included in cost of revenues. Sales taxes billed to customers are not included in revenues.  For our natural gas interests, we recognize
revenue in the month of production and delivery.

We operate our Lime and Limestone Operations within a single geographic region and derive all revenues from that segment from

the sale of lime and limestone products.  See Note 11 for disaggregation of revenues by the Lime and Limestone Operations segment and
Other, which we believe best depicts how the nature, amount, timing and uncertainty of revenues and cash flows are affected by economic
factors.

Accounts receivable.  We estimate the collectability of our trade receivables. A considerable amount of judgment is required in

assessing the ultimate realization of these receivables and determining our allowance for doubtful accounts. Uncollected trade receivables
are charged-off when identified by management to be unrecoverable. The majority of our trade receivables are unsecured. Payment terms
for our trade receivables are based on underlying purchase orders, contracts or purchase agreements. Credit losses relating to these
receivables have generally been within management expectations and historical trends.

Property, plant and equipment.    For major constructed assets, we include the costs for labor and materials plus interest and

internal and external project management costs that are directly related to the constructed assets in the capitalized cost.  Depreciation of
property, plant and equipment is being provided for by the straight-line method over estimated useful lives.

Maintenance and repairs are charged to expense as incurred; renewals and betterments are capitalized. When units of property are
retired or otherwise disposed of, their cost and related accumulated depreciation are removed from the accounts, and any resulting gain or
loss is credited or charged to income.

We expense all exploration costs as incurred as well as costs incurred at an operating quarry or mine, other than capital
expenditures and inventory. Costs to acquire mineral reserves or mineral interests are capitalized upon acquisition.  Development costs
incurred to develop new mineral reserves, to expand the capacity of a quarry or mine, or

17

Table of Contents

to develop quarry or mine areas substantially in advance of current production are capitalized once proven and probable reserves exist and
can be economically produced.  For each quarry or mine, capitalized costs to acquire and develop mineral reserves are depleted using the
units-of-production method based on the proven and probable reserves for such quarry or mine.

We review long-lived assets for impairment and, when events or circumstances indicate the carrying amount of an asset may not

be recoverable, we determine if impairment of value exists. If the estimated undiscounted future net cash flows are less than the carrying
amount of the asset, an impairment exists, and an impairment loss must be calculated and recorded. If an impairment exists, the impairment
loss is calculated based on the excess of the carrying amount of the asset over the asset’s fair value. Any impairment loss is treated as a
permanent reduction in the carrying value of the asset.  During 2019, we recognized an impairment charge of $0.9 million to adjust the
carrying value of certain long-lived assets related to our natural gas interests.

Environmental costs and liabilities.  We record environmental accruals in other liabilities, based on studies and estimates, when it

is probable we have incurred a reasonably estimable cost or liability. The accruals are adjusted when further information warrants an
adjustment. Environmental expenditures that extend the life, increase the capacity or improve the safety or efficiency of Company-owned
assets or are incurred to mitigate or prevent future possible environmental issues are capitalized. Other environmental costs are expensed
when incurred.

Contingencies.  We are party to proceedings, lawsuits and claims arising in the normal course of business relating to regulatory,

labor, product and other matters. We are required to estimate the likelihood of any adverse judgments or outcomes with respect to these
matters, as well as potential ranges of possible losses. A determination of the amount of reserves required, if any, for these contingencies is
made after careful analysis of each individual matter, including coverage under our insurance policies. This determination may change in
the future because of new information or developments.

Income taxes.  We utilize the asset and liability approach in reporting our income taxes. Deferred income tax assets and liabilities
are computed for differences between the financial statement and tax bases of assets and liabilities that will result in taxable or deductible
amounts in the future based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable
income. We establish valuation allowances when necessary to reduce deferred tax assets to the amount more likely than not to be realized.
Income tax related interest and penalties are included in income tax expense.  We also assess individual tax positions to determine if they
meet the criteria for some or all of the benefits of that position to be recognized in our financial statements and only recognize tax positions
that meet the more-likely-than-not recognition threshold.

Stock-based compensation.  We expense all stock-based payments to employees and directors, including grants of stock options

and restricted stock, in our Consolidated Statements of Income based on their fair values. Compensation cost is recognized ratably over the
vesting period for all stock-based awards.

2019 vs. 2018

Revenues for 2019 increased to $158.3 million from $144.4 million in 2018, an increase of $13.8 million, or 9.6%. Revenues from our

Lime and Limestone Operations in 2019 increased $15.1 million, or 10.6%, to $157.0 million from $141.9 million in 2018. The increase in
revenues from our Lime and Limestone Operations was primarily due to increased sales volumes of our lime and limestone products,
principally to our construction and environmental customers. In addition, we realized a  2.0% average increase in prices for our lime and
limestone products in 2019, compared to 2018.  Revenues also included $1.3 million and $2.5 million in 2019 and 2018, respectively, from our
natural gas interests.

Our gross profit increased to $41.7 million for 2019 from $30.5 million for 2018, an increase of $11.2 million, or 36.7%. Gross profit

from our Lime and Limestone Operations for 2019 was $42.0 million, compared to $29.5 million in 2018, an increase of $12.6 million, or 42.6%.
The increase in gross profit in 2019, compared to 2018, resulted primarily from increased revenues discussed above, lower fuel costs and
increased operating efficiencies associated with the new kiln at our St. Clair facility, which began producing commercially saleable quicklime
in the second quarter 2019.  Gross profit also included the impact of a $(0.4) loss in 2019 and $1.0 million profit in 2018 from our natural gas
interests.

Selling, general and administrative expenses (“SG&A”) increased to $11.5 million for 2019, an increase of $1.0 million, or 9.7%,
compared to $10.5 million for 2018. As a percentage of revenues, SG&A was 7.3% in each of 2019 and 2018.  The increase in SG&A was
primarily due to increased compensation-related and legal expenses in 2019, compared to 2018.

In the fourth quarter 2019, we recognized an impairment charge of $0.9 million ($0.7 million, net of tax) to adjust the carrying values

of the long-lived assets related to our natural gas interests.  Prices for natural gas and natural gas liquids decreased substantially during
2019, compared to 2018, which led to the impairment of the assets.

Interest expense was $0.2 million in each of 2019 and 2018, as we had no outstanding debt during either 2019 or 2018.

Interest and other income, net was $1.9 million in 2019, compared to $1.8 million in 2018.  The increase in interest and other income,

net in 2019, compared to 2018, was primarily due to increased interest rates received on cash and cash equivalents balances in 2019.

Income tax expense was $4.8 million in 2019, for an effective rate of 15.7%, compared to $1.9 million in 2018, for an effective rate of

8.7%, an increase of $3.0 million.  Our effective income tax rates for 2019 and 2018 were reduced from the statutory rate primarily due to
research and development tax credits and statutory depletion in excess of cost depletion.

Net income increased to $26.1 million ($4.64 per share diluted) in 2019, compared to $19.7 million ($3.51 per share diluted) in 2018,

an increase of $6.4 million, or 32.4%.

2018 vs. 2017

Revenues for 2018 decreased to $144.4 million from $144.8 million in 2017, a decrease of $0.4 million, or 0.3%. Revenues from our

Lime and Limestone Operations in 2018 decreased $0.7 million, or 0.5%, to $141.9 million from $142.6 million in 2017. The decrease in
revenues from our Lime and Limestone Operations was primarily due to decreased sales volumes of our lime and limestone products,
principally to our construction and environmental customers, partially offset by increased sales volumes to our steel customers. In addition,
we realized a  1.3% average increase in prices for our lime and limestone products in 2018, compared to 2017.  Revenues also included $2.5
million and $2.2 million in 2018 and 2017, respectively, from our natural gas interests.

Our gross profit decreased to $30.5 million for 2018 from $34.4 million for 2017, a decrease of $3.9 million, or 11.3%. Gross profit

from our Lime and Limestone Operations for 2018 was $29.5 million, compared to $33.7 million in 2017, a decrease of $4.2 million, or 12.4%.
The decrease in gross profit in 2018, compared to 2017, resulted primarily from increased quarrying and transportation costs.  Gross profit
also included $1.0 million and $0.7 million in 2018 and 2017, respectively, from our natural gas interests.

SG&A increased to $10.5 million for 2018, an increase of $0.3 million, or 3.3%, compared to $10.2 million for 2017. As a percentage

of revenues, SG&A increased to 7.3% in 2018 from 7.0% in 2017, due primarily to the decrease in revenues and an increase in compensation-
related expenses in 2018.

Interest expense was $0.2 million in each of 2018 and 2017, as we had no outstanding debt during either 2018 or 2017.

Interest and other income, net was $1.8 million in 2018, compared to $1.0 million in 2017.  The increase in interest and other income,

net in 2018, compared to 2017, was primarily due to increased interest rates received on cash and cash equivalents balances in 2018.

Income tax expense (benefit) was an expense of $1.9 million in 2018, for an effective rate of 8.7%, compared to a benefit of $2.2
million in 2017, for an effective rate of (8.8%), an increase in income tax expense of $4.1 million. The income tax benefit in 2017 included a
benefit of $7.4 million ($1.33 per share diluted) due to a reduction in the enacted federal income tax rates in the United States as a result of
the 2017 Tax Act and the one-time impact of the lower rates on our deferred tax liabilities, net. Our effective income tax rate for 2018 was
reduced by research and development tax credits associated with the construction of the St. Clair kiln project.

Net income decreased to $19.7 million ($3.51 per share diluted) in 2018, compared to $27.1 million ($4.86 per share diluted) in 2017, a

decrease of $7.5 million, or 27.5%.

FINANCIAL CONDITION.

Capital Requirements.  We require capital primarily for normal recurring capital and re-equipping projects, modernization and

expansion and development projects and acquisitions. Our capital needs are expected to be met principally from cash on hand, cash flows
from operations and our $75.0 million revolving credit facility.

20

Table of Contents

We expect to spend approximately $12.0 million per year over the next several years in our Lime and Limestone Operations for
normal recurring capital and re-equipping projects at our plants and facilities to maintain or improve efficiency, ensure compliance with
Environmental Laws, meet customer needs and reduce costs. As of December 31, 2019, we had $2.1 million in open orders or contractual
commitments for our Lime and Limestone Operations.

Liquidity and Capital Resources.  Net cash provided by operating activities was $47.0 million in 2019, compared to $38.7 million in
2018, an increase of $8.3 million, or 21.4%. Our net cash provided by operating activities is composed of net income, depreciation, depletion
and amortization (“DD&A”), other non-cash items included in net income and changes in working capital. In 2019, net cash provided by
operating activities was principally composed of $26.1 million net income, $17.6 million DD&A,  $4.9 million increase in deferred income
taxes, $0.9 million impairment of long-lived assets, and $1.5 million stock-based compensation, partially offset by a $4.4 million decrease
from changes in working capital.  In 2019, the changes in working capital were principally composed of a $3.3 million increase in trade
receivables, net.  In 2018, net cash provided by operating activities was principally composed of $19.7 million net income, $17.6 million
DD&A, and $1.5 million stock-based compensation, partially offset by a $0.7 million decrease from changes in working capital.  Changes in
working capital in 2018 were primarily due to a $3.1 million increase in trade receivables, net and a $1.4 million decrease in prepaid expenses
and other current assets.

Net cash used in investing activities was $26.5 million for 2019, compared to $53.2 million in 2018.  Net cash used in investing

activities included $5.6 million and $26.2 million paid on the St. Clair kiln project in 2019 and 2018, respectively. Net cash used in investing
activities in 2019 also included $8.0 million for specialized equipment at the Batesville Quarry and $2.8 million for a new slurry terminal in the
Dallas-Fort Worth area.  Net cash used in investing activities in 2018 also included $9.4 million for land purchases in Texas, Arkansas and
Oklahoma, $3.1 million for specialized equipment at the Batesville Quarry and $1.7 million for updating our fleet of slakers and trucks used in
the production and transportation of our lime slurry products.  The balance of net cash used in investing activities in 2019 and 2018 was
primarily for normal recurring capital and re-equipping projects at our plants and facilities. 

Net cash used in financing activities primarily consisted of $33.1 million for dividend payments in 2019, including a special cash

dividend of $30.0 million, compared to $3.0 million for dividend payments in 2018, and $0.4 million to repurchase shares of our common
stock in each of 2019 and 2018.

Our cash and cash equivalents at December 31, 2019 decreased to $54.3 million from $67.2 million at December 31, 2018.

Banking Facilities and Debt.    Our credit agreement with Wells Fargo Bank, N.A. (the “Lender”), as amended as of May 2, 2019

and November 21, 2019, provides for a $75 million revolving credit facility (the “Revolving Facility”) and an incremental four-year accordion
feature to borrow up to an additional $50 million on the same terms, subject to approval by the Lender or another lender selected by us. 
The credit agreement also provides for a $10 million letter of credit sublimit under the Revolving Facility.  The Revolving Facility and any
incremental loans mature on May 2, 2024. 

Interest rates on the Revolving Facility are, at our option, LIBOR plus a margin of 1.000% to 2.000%, or the Lender’s Prime Rate

plus a margin of 0.000% to 1.000%; and a commitment fee range of 0.200% to 0.350% on the undrawn portion of the Revolving Facility.  The
Revolving Facility interest rate margins and commitment fee are determined quarterly in accordance with a pricing grid based upon our Cash
Flow Leverage Ratio, defined as the ratio of the Company’s total funded senior indebtedness to earnings before interest, taxes,
depreciation, depletion, amortization and stock-based compensation expense (“EBITDA”) for the 12 months ended on the last day of the
most recent calendar quarter, plus pro forma EBITDA from any businesses acquired during the period.  Pursuant to a security agreement,
dated August 25, 2004, the Revolving Facility is secured by the Company’s existing and hereafter acquired tangible assets, intangible
assets and real property.  The maturity of the Revolving Facility and any incremental loans can be accelerated if any event of default, as
defined under the credit agreement, occurs.  Our maximum Cash Flow Leverage Ratio is 3.50 to 1.

We may pay dividends so long as we remain in compliance with the provisions of our credit agreement, and may purchase, redeem

or otherwise acquire shares of our common stock so long as our pro forma Cash Flow Leverage

21

Table of Contents

Ratio is less than 3.00 to 1.00 and no default or event of default exists or would exist after giving effect to such stock repurchase.

We had no debt outstanding as of December 31, 2019 or 2018.  We had $0.4 million of letters of credit issued under the Revolving

Facility as of December 31, 2019, which count as draws against the available commitment under the Revolving Facility.

Common Stock Buybacks.  We spent $0.4 million, $0.4 million and $0.3 million in 2019, 2018 and 2017, respectively, to repurchase

treasury shares.

(1) Represents operating leases for railcars, corporate office space and some equipment that are either non-cancelable or subject to

significant penalty upon cancellation.

(2) Of these obligations, $1,128 were recorded on the Consolidated Balance Sheet at December 31, 2019.

(3) Purchase obligations includes enforceable agreements to purchase goods or services that specify all significant terms, including fixed
or minimum quantities to be purchased, fixed-price provisions, and the approximate timing of the transaction, and are either non-
cancelable or subject to significant penalty upon cancellation.

We believe that cash on hand and cash flows from operations will be sufficient to meet our operating needs, ongoing capital

needs, including our current and possible future modernization and expansion and development projects, and liquidity needs and allow us
to pay our regular cash dividends for the near future.

Off-Balance Sheet Arrangements.  We do not utilize off-balance sheet financing arrangements; however, we lease railcars,

corporate office space and some equipment used in our operations under operating lease agreements that are either non-cancelable or
subject to significant penalty upon cancellation, and have various limestone mineral leases. As of December 31, 2019, the total future lease
payments under our various operating and limestone mineral leases totaled $3.3 million and $1.5 million, respectively, and are due in
payments as summarized in the table above.

ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES
ABOUT MARKET RISK.

INTEREST RATE RISK.

We could be exposed to changes in interest rates, primarily as a result of floating interest rates on the Revolving Facility.  There
was no outstanding balance on the Revolving Facility subject to interest rate risk at December 31, 2019.  Any future borrowings under the
Revolving Facility would be subject to interest rate risk. See Note 3 of Notes to Consolidated Financial Statements.

FOREIGN EXCHANGE RISK.

We could be exposed to changes in the Euro to U.S. Dollar exchange rate for our 0.3 million Euros obligations for contracts related
to the purchase and installation of equipment at December 31, 2019.  We entered into foreign exchange hedges to fix our U.S. Dollar liability
at $0.4 million.  See Notes 1(f) and 10 of Notes to Consolidated Financial Statements.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Shareholders
United States Lime & Minerals, Inc.

Opinion on the financial statements
We have audited the accompanying consolidated balance sheets of United States Lime & Minerals, Inc.
(a Texas Corporation) and subsidiaries (the “Company”) as of December 31, 2019 and 2018, the related
consolidated statements of income, comprehensive income, stockholders’ equity, and cash flows for
each  of  the  three  years  in  the  period  ended  December  31,  2019,  and  the  related  notes  (collectively
referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all
material respects, the financial position of the Company as of December 31, 2019 and 2018, and the
results of its operations and its cash flows for each of the three years in the period ended December 31,
2019, in conformity with accounting principles generally accepted in the United States of America.

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, 2019, based on criteria established in the 2013 Internal Control—Integrated Framework
issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”), and our
report dated February 28, 2020 expressed an unqualified opinion.

Change in accounting principle
As discussed in Note 2 to the consolidated financial statements, the Company has changed its method
of accounting for leases on January 1, 2019 using the modified retrospective method due to the adoption
of Accounting Standard Codification 842, “Leases”.

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  supporting  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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Shareholders
United States Lime & Minerals, Inc.

Opinion on internal control over financial reporting
We have audited the internal control over financial reporting of United States Lime & Minerals, Inc. (a
Texas  corporation)  and  subsidiaries  (the  “Company”)  as  of  December  31,  2019,  based  on  criteria
established in the 2013 Internal Control—Integrated Framework issued by the Committee of Sponsoring
Organizations of the Treadway Commission (“COSO”). In our opinion, the Company maintained, in all
material respects, effective internal control over financial reporting as of December 31, 2019, based on
criteria established in the 2013 Internal Control—Integrated Framework issued by COSO.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight
Board (United States) (“PCAOB”), the consolidated financial statements of the Company as of and for the
year  ended  December  31,  2019,  and  our  report  dated  February  28,  2020  expressed  an  unqualified
opinion on those financial statements.

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.

(a)         Organization and Presentation

United States Lime & Minerals, Inc.

Notes to Consolidated Financial Statements

(dollars in thousands, except per share amounts)

Years Ended December 31, 2019, 2018 and 2017

United States Lime & Minerals, Inc. (the “Company”) is a manufacturer of lime and limestone products, supplying primarily the
construction (including highway, road and building contractors), industrial (including paper and glass manufacturers),
environmental (including municipal sanitation and water treatment facilities and flue gas treatment processes), metals (including
steel producers), oil and gas services, roof shingle manufacturers and agriculture (including poultry and cattle feed producers)
industries. The Company is headquartered in Dallas, Texas and operates lime and limestone plants and distribution facilities in
Arkansas, Colorado, Louisiana, Oklahoma and Texas through its wholly owned subsidiaries, Arkansas Lime Company, Colorado
Lime Company, Texas Lime Company, U.S. Lime Company, U.S. Lime Company – Shreveport, U.S. Lime Company – St. Clair and
U.S. Lime Company – Transportation. In addition, the Company, through its wholly owned subsidiary, U.S. Lime Company – O &
G, LLC, has royalty and non-operated working interests in natural gas wells located in Johnson County, Texas, in the Barnett Shale
Formation.

During 2019, the Company’s natural gas interests did not reach any of the quantitative thresholds for a reportable segment, and
the results from its natural gas interests are not expected to be of significance in future periods.  The revenues, gross profit and
operating profit of the natural gas interests are included in Other for reportable segment disclosures.  Disclosures for 2018 and
2017 have been recast to be consistent with the 2019 presentation.

(b)         Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany balances and
transactions have been eliminated.

(c)         Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of
America (“US GAAP”) requires management to make estimates and judgments that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from those estimates and judgments.

(d)         Statements of Cash Flows

For purposes of reporting cash flows, the Company considers all bank deposits and highly liquid debt instruments, such as U.S.
Treasury bills and notes, with maturities, at the time of purchase, of three months or less to be cash equivalents. Cash equivalents
are carried at cost plus accrued interest, which approximates fair market value. Supplemental cash flow information is presented
below:

(e)         Revenue Recognition

United States Lime & Minerals, Inc.

Notes to Consolidated Financial Statements (Continued)

(dollars in thousands, except per share amounts)

Years Ended December 31, 2019, 2018 and 2017

The Company recognizes revenue for its Lime and Limestone Operations when (i) a contract with the customer exists and the
performance obligations are identified, (ii) the price has been established; and (iii) the performance obligations have been satisfied,
which is generally upon shipment.  Revenues include external freight billed to customers with related costs accounted for as
fulfillment costs and included in cost of revenues.  The Company’s returns and allowances are minimal.  External freight billed to
customers included in revenues was $28,397,  $25,637 and $23,489 for 2019, 2018 and 2017, respectively, which approximates the
amount of external freight included in cost of revenues. Sales taxes billed to customers are not included in revenues.  For its
natural gas interests, the Company recognizes revenue in the month of production and delivery.

The Company operates its Lime and Limestone Operations within a single geographic region and derives all revenues from that
segment from the sale of lime and limestone products.  See Note 11 for disaggregation of revenues by the Lime and Limestone
Operations segment and Other, which the Company believes best depicts how the nature, amount, timing and uncertainty of
revenue and cash flows are affected by economic factors.

 (f)         Fair Values of Financial Instruments

Fair value is defined as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction
between market participants at the measurement date.” The Company uses a three-tier fair value hierarchy, which classifies the
inputs used in measuring fair values, in determining the fair value of its financial assets and liabilities. These tiers include: Level 1,
defined as observable inputs such as quoted prices for identical instruments in active markets; Level 2, defined as observable
inputs other than Level 1 prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active,
or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or
liabilities and; Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to
develop its own assumptions. Specific inputs used to value the Company’s foreign exchange hedges were Euro to U.S. Dollar
exchange rates for the expected future payment dates for the Company’s commitments denominated in Euros.  There were no
changes in the methods and assumptions used in measuring fair value during the period.

The carrying values of cash and cash equivalents, trade receivables, other current assets, accounts payable and accrued expenses
approximate fair value due to the short maturity of these instruments.  The Company’s foreign exchange hedges are carried at fair
value at December 31, 2019 and 2018.  See Notes 1(p), 5 and 10. Financial liabilities measured at fair value on a recurring basis are
summarized below:

(g)         Concentration of Credit Risk and Trade Receivables

Financial instruments that potentially subject the Company to a concentration of credit risk consist principally of cash and cash
equivalents, trade receivables and derivative financial instruments. The Company places its cash and cash equivalents with high-
credit quality financial institutions and in highly rated commercial paper or U.S. Treasury bills and notes with maturities, at the time
of purchase, of three months or less.  The Company places its derivative financial instruments with financial institutions and other
firms that management believes have high credit ratings. The Company’s cash and cash equivalents at commercial banking
institutions normally exceed federally insured limits. For a discussion of the credit risks associated with the Company’s derivative
financial instruments, see Note 10.

The majority of the Company’s trade receivables are unsecured. Payment terms for all trade receivables are based on the
underlying purchase orders, contracts or purchase agreements. Credit losses relating to trade receivables have generally been
within management expectations and historical trends. Uncollected trade receivables are charged-off when identified by
management to be unrecoverable. Trade receivables are presented net of the related allowance for doubtful accounts, which
totaled $361 and $430 at December 31, 2019 and 2018, respectively. Additions and write-offs to the Company’s allowance for
doubtful accounts during the years ended December 31 are as follows:

Inventories are valued principally at the lower of cost, determined using the average cost method, or net realizable value. Costs for
raw materials and finished goods include materials, labor and production overhead. A summary of inventories is as follows:

For major constructed assets, the capitalized cost includes the price paid by the Company for labor and materials plus interest and
internal and external project management costs that are directly related to the constructed assets. Machinery and equipment at
December 31, 2019 and 2018 included $16,813 and $45,555, respectively, of construction in progress for various capital projects. No
interest costs were capitalized for the years ended December 31, 2019 and 2018. At December 31, 2019 and 2018, accounts payable

(dollars in thousands, except per share amounts)

Years Ended December 31, 2019, 2018 and 2017

expenses included $1,303 and $936, respectively, of capitalized costs. Depreciation of property, plant and equipment is being
provided for by the straight-line method over estimated useful lives as follows:

Buildings and building and leasehold improvements
Machinery and equipment
Furniture and fixtures
Automotive equipment

     3 - 25 years  
2 - 30 years  
3 - 10 years  
3 - 10 years  

Maintenance and repairs are charged to expense as incurred; renewals and betterments are capitalized. When units of property are
retired or otherwise disposed of, their cost and related accumulated depreciation are removed from the accounts, and any resulting
gain or loss is credited or charged to income.

The Company expenses all exploration costs as incurred as well as costs incurred at an operating quarry or mine, other than capital
expenditures and inventory. Costs to acquire mineral reserves or mineral interests are capitalized upon acquisition. Development
costs incurred to develop new mineral reserves, to expand the capacity of a quarry or mine, or to develop quarry or mine areas
substantially in advance of current production are capitalized once proven and probable reserves exist and can be economically
produced. For each quarry or mine, capitalized costs to acquire and develop mineral reserves are depleted using the units-of-
production method based on the proven and probable reserves for such quarry or mine.

The Company reviews its long-lived assets for impairment and, when events or circumstances indicate the carrying amount of an
asset may not be recoverable, the Company determines if impairment of value exists. If the estimated undiscounted future net cash
flows are less than the carrying amount of the asset, an impairment exists, and an impairment loss must be calculated and recorded.
If an impairment exists, the impairment loss is calculated based on the excess of the carrying amount of the asset over the asset’s
fair value. Any impairment loss is treated as a permanent reduction in the carrying value of the asset.

During 2019, the Company recognized an impairment charge of $930 to adjust the carrying value of certain long-lived assets related
to its natural gas interests.  Prices for natural gas and natural gas liquids decreased substantially during 2019, which led the
Company to determine that the estimated fair value of its natural gas assets was less than their carrying value.  Fair value was
determined as the present value of the estimated future cash flows of the natural gas interests.

(j)         Successful-Efforts Method Used for Natural Gas Interests

The Company uses the successful-efforts method to account for oil and gas exploration and development expenditures. Under this
method, drilling, completion and workover costs for successful exploratory wells and all development well costs are capitalized and
depleted using the units-of-production method. Costs to drill exploratory wells that do not find proved reserves are expensed.

(k)         Asset Retirement Obligations

The Company recognizes legal obligations for reclamation and remediation associated with the retirement of long-lived assets at
their fair value at the time the obligations are incurred (“AROs”). Over time, the liability for AROs is recorded at its present value
each period through accretion expense, and the capitalized cost is depreciated over the useful life of the related asset. Upon
settlement of the liability, the Company either settles the AROs for the recorded amount or recognizes a gain or loss.  The
Company’s AROs of $1,482 and $1,519 as of  December 31, 2019 and 2018, respectively, are included in Other liabilities and
Accrued expenses on the Company’s Consolidated Balance Sheets. As of December 31, 2019, assets, net of accumulated
depreciation,

associated with the Company’s AROs totaled  $826.  During 2019 and 2018, the Company spent $93 and $178, respectively, on its
AROs, and recognized accretion expense of $86,  $84 and $73 in 2019, 2018 and 2017, respectively, on its AROs.

The AROs were estimated based on studies and the Company’s process knowledge and estimates and are discounted using a
credit adjusted risk-free interest rate. The AROs are adjusted when further information warrants an adjustment. The Company
estimates annual expenditures of approximately $100 to $200 per year in years 2020 through 2024 relating to its AROs.

(l)         Other Assets, Net

Environmental expenditures that relate to current operations are expensed or capitalized as appropriate. Expenditures that relate to
an existing condition caused by past operations, and which do not contribute to current or future revenue generation, are
expensed. Liabilities are recorded at their present value when environmental assessments and/or remedial efforts are probable, and
the costs can be reasonably estimated. Generally, the timing of these accruals will coincide with completion of a feasibility study or
the Company’s commitment to a formal plan of action.

The Company incurred capital expenditures related to environmental matters of $1,156 in 2019,  $1,152 in 2018 and $440 in 2017.

The Company paid $5.89,  $0.54 and $0.54 of cash dividends per share of common stock in 2019, 2018 and 2017, respectively.  The
cash dividends for 2019 included a special dividend of $5.35 per share paid in 2019.

(o)         Stock-Based Compensation

The Company expenses all stock-based payments to employees and directors, including grants of stock options and restricted
stock, in the Company’s Consolidated Statements of Income based on their fair values. Compensation cost is recognized on a
straight-line basis over the vesting period.

(p)         Derivative Instruments and Hedging Activities

Every derivative instrument is recorded on the Company’s Consolidated Balance Sheets as either an asset or liability measured at
its fair value. Changes in the derivative’s fair value are recognized currently in earnings unless specific hedge accounting criteria
are met. If the derivative is designated as a cash flow hedge, changes in fair value are recognized in comprehensive income or loss
until the hedged item is recognized in earnings.  The Company estimated fair value utilizing the cash flows valuation technique.
The fair values of derivative contracts that expire in less than one year are recognized as current assets or liabilities. Those that
expire in more than one year are recognized as long-term assets or liabilities. See Notes 1(f), 5 and 10.

(q)         Income Taxes

The Company utilizes the asset and liability approach in its reporting for income taxes. Deferred income tax assets and liabilities are
computed for differences between the financial statement and tax bases of assets and liabilities that will result in taxable or
deductible amounts in the future based on enacted tax laws and rates applicable to the periods in which the differences are
expected to affect taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the
amount more likely than not to be realized. Income tax related interest and penalties are included in income tax expense.

The Company also assesses individual tax positions to determine if they meet the criteria for some or all of the benefits of that
position to be recognized in the Company’s financial statements. The Company only recognizes tax positions that meet the more-
likely-than-not recognition threshold.

(r)         Comprehensive Income

Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. Certain
changes in assets and liabilities, such as mark-to-market gains or losses of interest rate and foreign exchange hedges, are reported
as a separate component of the stockholders’ equity section of the balance sheet. Such items, along with net income, are
components of comprehensive income. See Notes 1(p), 5 and 10.

(2) New Accounting Pronouncements

In February 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update No. 2016-02

(“ASU 2016-02”), “Leases,” which requires the recognition of lease assets and lease liabilities by lessees for all leases greater than one year
in duration and classified as operating leases under previous guidance.  For operating leases, a lessee is required to recognize at inception a
right-of-use asset and a lease liability equal to the net present value of the lease payments, with lease expense recognized over the lease
term on a straight-line basis.  For leases with a term of one year or less, ASU 2016-02 allows a reporting entity to make an accounting policy
election to not recognize a right-of-use asset and a lease liability, and to recognize lease expense on a straight-line basis.  The Company
adopted ASU 2016-02 at January 1, 2019, using the optional transition method.  Under the optional transition method, a reporting entity
continues to apply legacy guidance, including disclosure requirements, in the comparative periods presented in the year of adoption,
recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption, if any.  The Company
elected the package of practical expedients permitted under the transition guidance, which, among other things, carried forward the
historical lease classification.  The Company also elected the component practical expedient, which includes lease and non-lease
components as a single component in accounting for a lease.  Adoption of ASU 2016-02 resulted in an increase in assets of $3.9 million with
corresponding liabilities of $3.9 million and no impact on retained earnings at January 1, 2019.

In February 2018, the FASB issued Accounting Standards Update No. 2018-02 (“ASU 2018-02”),  “Reclassification of Certain Tax

Effects from Accumulated Other Comprehensive Income.”  ASU 2018-02 allows a reclassification from accumulated other comprehensive
income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017 (the “2017 Tax Act”). The Company
adopted ASU 2018-02 at January 1, 2019.  Adoption of this standard had no impact on the Company’s Consolidated Financial Statements.

In June 2016, the FASB issued ASU 2016-13 (“ASU 2016-13”),  “Financial Instruments - Credit Losses (Topic 326)”. The new

standard is effective for public companies, excluding smaller reporting companies, for reporting periods beginning after December 15, 2019
and for smaller reporting companies, for reporting periods beginning after December 15, 2022, including interim periods within those fiscal
years. The standard replaces the incurred loss impairment methodology under current US GAAP with a methodology that reflects expected
credit losses and requires the use of a forward-looking expected credit loss model for accounts receivables, loans, and other financial
instruments. The standard requires a modified retrospective approach through a cumulative-effect adjustment to retained earnings as of the
beginning of the first reporting period in which the guidance is effective. The Company plans to adopt ASU 2016-13 as of January 1, 2020. 
Implementation of ASU 2016-03 will not have a material effect on the Company’s Consolidated Financial Statements.

(3) Banking Facilities and Debt

The Company’s credit agreement with Wells Fargo Bank, N.A. (the “Lender”), as amended as of May 2, 2019 and November 21,

2019, provides for a $75,000 revolving credit facility (the “Revolving Facility”) and an incremental four-year accordion feature to borrow up
to an additional $50,000 on the same terms, subject to approval by the Lender or another lender selected by the Company.  The credit
agreement also provides for a $10,000 letter of credit sublimit under the Revolving Facility.  The Revolving Facility and any incremental
loans mature on May 2, 2024.

Interest rates on the Revolving Facility are, at the Company’s option, LIBOR plus a margin of 1.000% to 2.000%, or the Lender’s
Prime Rate plus a margin of 0.000% to 1.000%; and a commitment fee range of 0.200% to 0.350% on the undrawn portion of the Revolving
Facility.  The Revolving Facility interest rate margins and commitment fee are determined quarterly in accordance with a pricing grid based
upon the Company’s Cash Flow Leverage Ratio, defined as the ratio of the Company’s total funded senior indebtedness to earnings before
interest, taxes, depreciation, depletion, amortization and stock-based compensation expense (“EBITDA”) for the 12 months ended on the
last day of the most recent calendar quarter, plus pro forma EBITDA from any businesses acquired during the period.  Pursuant to a
security agreement, dated August 25, 2004, the Revolving Facility is secured by the Company’s existing and hereafter acquired tangible
assets, intangible assets and real property.  The maturity of the Revolving Facility and any incremental loans can be accelerated if any
event of default, as defined under the credit agreement, occurs.  The Company’s maximum Cash Flow Leverage Ratio is 3.50 to 1.

The Company may pay dividends so long as it remains in compliance with the provisions of the Company’s credit agreement, and
may purchase, redeem or otherwise acquire shares of its common stock so long as its pro forma Cash Flow Leverage Ratio is less than 3.00
to 1.00 and no default or event of default exists or would exist after giving effect to such stock repurchase.

The Company had no debt outstanding at December 31, 2019 or 2018.  The Company had $400 of letters of credit issued at

December 31, 2019, which count as draws against the available commitment under the Revolving Facility.

(4) Leases

The Company has operating leases for the use of equipment, corporate office space, and some of its terminal and distribution

facilities.  The leases have remaining lease terms of 0 to 8 years, with a weighted-average remaining lease term of 3 years at December 31,
2019.  Some operating leases include options to extend the leases for up to 5 years.  At January 1, 2019, upon implementation of ASU 2016-
02, the liability for the Company’s operating leases was discounted to present value using a weighted-average discount rate of 3.5%.  Total
lease and rent expense was $2,133,  $2,260 and $2,359 for 2019, 2018 and 2017, respectively.  The components of net operating lease costs
for 2019 were as follows (in thousands):

The $7,447 benefit of reduced federal income tax rates in 2017 resulted from the 2017 Tax Act, which was signed into law on

December 22, 2017.  The 2017 Tax Act reduced the enacted federal income tax rate for corporations from 35% to 21% beginning in
2018.  Applying the lower federal income tax rate to the Company’s book to tax differences resulted in a one-time reduction to the
Company’s deferred tax liabilities, net, recorded as an income tax benefit in the Consolidated Statements of Income for 2017. The research
and development tax credits in 2019, 2018 and 2017 were primarily associated with the construction of the new kiln at St. Clair.

The Company had no federal net operating loss carry forwards at December 31, 2019. The Company reduces deferred tax assets by

a valuation allowance if, based on the weight of available evidence, it is “more likely than not” that some portion or all of the deferred tax
assets will not be realized.  Deferred tax assets are considered fully recognizable because of the Company’s recent income history and
expectations of income in the future.  The Company’s federal income tax returns for the year ended December 31, 2016 and subsequent
years remain subject to examination.  The Company’s income tax returns in certain state income tax jurisdictions remain subject to
examination for various periods for the year ended December 31, 2016 and subsequent years.  The Company treats interest and penalties on
income tax liabilities as income tax expense.

(7)  Employee Retirement Plans

The Company has a contributory retirement (401(k)) savings plans for non-union employees and for union employees of Arkansas

Lime Company and Texas Lime Company. Company contributions to these plans were $259, $251 and $209 in 2019, 2018 and 2017,
respectively.

(8)  Stock-Based Compensation

The Company has a long-term incentive plan, the Amended and Restated 2001 Long-Term Incentive Plan (the “2001 Plan”). The

2001 Plan provides for stock options, restricted stock and dollar-denominated cash awards, including performance-based awards. In
addition to stock options, restricted stock and cash awards, the 2001 Plan provides for the grant of stock appreciation rights, deferred stock
and other stock-based awards to directors, officers, employees and consultants.

The number of shares of common stock that may be subject to outstanding awards granted under the 2001 Plan (determined

immediately after the grant of any award) may not exceed 874,589 from the inception of the 2001 Plan. In addition, no individual may receive
awards in any one calendar year of more than 100,000 shares of common stock. Stock options granted under the 2001 Plan expire ten years
from the date of grant and generally become exercisable, or

vest, immediately. Restricted stock generally vests over periods of one-half to three years. Upon the exercise of stock options, the
Company issues common stock from its non-issued authorized or treasury shares that have been reserved for issuance pursuant to the
2001 Plan. At December 31, 2019, the number of shares of common stock remaining available for future grants of stock options, restricted
stock or other forms of stock-based compensation under the 2001 Plan was 149,400.

The Company recorded $1,524, $1,489 and $1,405 for stock-based compensation expense related to stock options and shares of
restricted stock for 2019, 2018 and 2017, respectively. The amounts included in cost of revenues were $170,  $154 and $144 and in selling,
general and administrative expense were $1,354,  $1,335, and $1,261, for 2019, 2018 and 2017, respectively.

There were no non-vested stock options at December 31, 2019, and the weighted-average remaining contractual life of the
outstanding and exercisable stock options at such date was 6.64 years. The total compensation cost not yet recognized for restricted stock
at December 31, 2019 was $1,361, which will be recognized over the weighted average of 1.07 years.

The fair value for the stock options was estimated at the date of grant using a lattice-based option valuation model, with the

following weighted-average assumptions for the 2019, 2018 and 2017 grants: risk-free interest rates of 1.69% to 2.33% (weighted average
1.89%) in 2019,  2.51% to 2.80% (weighted average 2.59%) in 2018 and 1.45% to 1.81% (weighted average 1.73%) in 2017; a dividend yield of
0.60% to 0.67% (weighted average 0.62%) in 2019,  0.73% to 0.76% (weighted average 0.75%) in 2018 and 0.54% to 0.67% (weighted average
of 0.57%) in 2017; and a volatility factor of .244 to .247 (weighted average .245) in 2019,  .249 to .256 (weighted average .250) in 2018 and .258
to .265

(dollars in thousands, except per share amounts)

Years Ended December 31, 2019, 2018 and 2017

(weighted average .260) in 2017, based on the monthly per-share closing prices for three years preceding the date of issuance. In addition,
the fair value of these options was estimated based on an expected life of three to five years. The fair value of restricted stock is based on
the closing per-share price of the Company’s common stock on the date of grant.

(9)  Share Repurchases

The Company accounts for the repurchase of common stock using the cost method, with common stock in treasury classified in
the  Company’s  Consolidated  Balance  Sheets  as  a  reduction  in  stockholders’  equity.    In  December  2015,  the  Company  commenced  a
publicly announced share repurchase program to repurchase up to $10,000 of its common stock.  On November 30, 2019, the repurchase
program expired.  No shares were repurchased under the program in 2019, 2018 or 2017.

During 2019, pursuant to provisions in the 2001 Plan that allow employees and directors to pay the tax withholding liability upon
the  lapse  of  restrictions  on  restricted  stock  in  either  cash  and/or  delivery  of  shares  of  the  Company’s  common  stock,  the  Company
repurchased 5,475 shares at a weighted-average price of $81.10 per share.

(10)  Commitments and Contingencies

The Company is party to lawsuits and claims arising in the normal course of business, none of which, in the opinion of

management, is expected to have a material adverse effect on the Company’s financial condition, results of operations, cash flows or
competitive position.

The Company is not contractually committed to any planned capital expenditures until actual orders are placed for equipment or

services. At December 31, 2019, the Company had $979 for open equipment and construction contracts. At December 31, 2019, the
Company had a contract related to a capital project at its Arkansas facility that required future payments totaling 0.3 million Euros, or
$381.  To hedge against potential losses due to changes in the Euro to U.S. Dollar exchange rates, the Company has entered into foreign
exchange (“FX”) hedges with Wells Fargo Bank, N.A. as the counterparty to the hedges to fix the exchange rate for the 0.3 million
Euros.  The hedges have been effective as defined under applicable accounting rules.  Therefore, changes in fair value of the FX hedges are
reflected in comprehensive income.  The Company will be exposed to credit losses in the event of non-performance by the counterparty to
the hedges.  Due to the strengthening of the Euro, compared to the U.S. Dollar during 2019, the fair value of the FX hedges resulted in a
liability of $1 at December 31, 2019,  and a liability of $16 at December 31, 2018, which is included in Accrued expenses in the Company’s
Consolidated Balance Sheets.  See Notes 1(f), 1(p) and 5.

(11)  Reportable Segment

The Company has identified one reportable segment based on the distinctness of the Company’s activities and products: lime and

limestone operations. All operations are in the United States. In evaluating the operating results of the Company, management primarily
reviews revenues, gross profit and operating profit from the lime and limestone operations.  Operating profit from its lime and limestone
operations includes all of the Company’s selling, general and administrative costs. The Company does not allocate interest income and
expense and other expense to its lime and limestone operations. 

During 2019, the Company’s natural gas interests did not reach any of the quantitative thresholds for a reportable segment, and
the Company does not expect the results from its natural gas interests to be of significance in future periods.  The revenues, gross profit
and operating profit from the Company’s natural gas interests are included in Other for the Company’s reportable segment
disclosures.  Other identifiable assets include assets related to its natural gas interests, unallocated corporate assets and cash items.
 Segment disclosures for 2018 and 2017 have been recast to be consistent with the 2019 presentation.

ITEM 9.  CHANGE
S IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE.

None.

ITEM 9A.  CONTROL
S AND PROCEDURES.

Evaluation of disclosure controls and procedures.  The Company’s management, with the participation of the Company’s Chief

Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), evaluated the effectiveness of the Company’s disclosure controls and
procedures as of the end of the period covered by this Report. Based on that evaluation, the CEO and CFO concluded that the Company’s
disclosure controls and procedures as of the end of the period covered by this Report were effective.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The management of the Company is responsible for establishing and maintaining adequate internal control over financial
reporting. The Company’s internal control over financial reporting is a process designed under the supervision of the Company’s CEO and
CFO to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the Company’s financial
statements for external purposes in accordance with generally accepted accounting principles.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. All internal

control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can
provide only reasonable assurance with respect to financial statement preparation and presentation. Additionally, 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.

As of December 31, 2019, management assessed the effectiveness of the Company’s internal control over financial reporting based

on the criteria for effective internal control over financial reporting established in the 2013 “Internal Control—Integrated Framework,”
issued by the Committee of Sponsoring Organizations of the Treadway Commission (the “COSO criteria”). Based on the assessment,
management determined that the Company maintained effective internal control over financial reporting as of December 31, 2019, based on
the COSO criteria.

Grant Thornton LLP, the Company’s independent registered public accounting firm, has issued an audit report on the
effectiveness of the Company’s internal control over financial reporting, which appears elsewhere in this Report on Form 10-K.

Changes in internal control over financial reporting.  No change in the Company’s internal control over financial reporting

occurred during the Company’s most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, the
Company’s internal control over financial reporting.

General

DESCRIPTION OF UNITED STATES LIME & MINERALS, INC.’S
SECURITIES REGISTERED UNDER SECTION 12 OF THE
SECURITIES EXCHANGE ACT OF 1934, AS AMENDED

United States Lime & Minerals, Inc. (the “Company,” “we,” or “our”) is incorporated in the State of Texas. The rights of our shareholders are
generally covered by Texas law and our articles of incorporation and bylaws (each as amended and restated and in effect on the date hereof). The terms of
our common stock are therefore subject to Texas law, including the Texas Business Organizations Code (the “TBOC”), and the common and constitutional
law of Texas.

This exhibit describes the general terms of our common stock. This description is a summary and does not purport to be complete. Our articles of

incorporation and bylaws are incorporated by reference as exhibits to the Annual Report on Form 10-K of which this exhibit is a part, and amendments or
restatements of each will be filed with the Securities and Exchange Commission (the “SEC”) in future periodic or current reports in accordance with the
rules of the SEC. You are encouraged to read these documents.

For more detailed information about the rights of holders of our common stock, you should refer to our articles of incorporation and bylaws and the

applicable provisions of Texas law, including the TBOC.

Authorized Capital Stock

We are authorized to issue 15,000,000 shares of common stock, $0.10 par value, and 500,000 shares of preferred stock, $5.00 par value.

Common Stock

Voting Rights

Holders of our common stock are entitled to one vote per share in the election of directors and on all other matters submitted to a vote of

shareholders. No shareholder has the right of cumulative voting.

With respect to any matter other than the election of directors or a matter for which the affirmative vote of the holders of a specified portion of the
shares of our common stock entitled to vote is required by Texas law or our articles of incorporation, the act of the shareholders shall be the affirmative
vote of the holders of a majority of the shares entitled to vote on, and voted for or against, the matter at a meeting of shareholders at which a quorum is
present. Directors shall be elected by a plurality of the votes cast by the holders of shares entitled to vote in the election of directors at a meeting of
shareholders at which a quorum is present. We do not have a classified board of directors. Our directors are elected for one-year terms.

Dividend Rights

Holders of our common stock are entitled to dividends when, as and if declared by our Board of Directors out of funds legally available therefor.

Liquidation Rights

If we liquidate,  a holder of common stock will be entitled to share ratably with the other shareholders in the distribution of all assets that we have

left after we pay all of our liabilities and make any necessary distributions to holders of our preferred stock.

Other

Our common stock has no preemptive or conversion rights and is not entitled to the benefits of any redemption or sinking fund provision. The

outstanding shares of our common stock are fully paid and non-assessable.

Preferred Stock

The Company may issue shares of preferred stock from time to time upon the approval of our Board of Directors in one or more series without further

stockholder approval. The Board of Directors may designate the number of shares to be issued in such series and the rights, preferences, privileges and
restrictions granted to, or imposed on, the holders of such shares. If issued, such shares of preferred stock could have dividends and liquidation
preferences over our shares of common stock, and may otherwise affect the rights of the holders of the common stock. The rights of the holders of our
common stock will, therefore, generally be subject to the rights of the holders of any existing outstanding shares of preferred stock with respect to
dividends, liquidation preferences and other matters.  As of the date hereof, we have no outstanding shares of preferred stock.

Certain Business Combination Restrictions in Texas Law

Section 21.606 of the TBOC restricts certain business combinations between us and an affiliated shareholder (beneficial ownership of 20% or more of
the voting power of our stock entitled to vote for directors) for three years after the shareholder becomes an affiliated shareholder. The restrictions do not
apply if our Board of Directors approved the transaction that caused the shareholder to become an affiliated shareholder, or if the business combination is
approved by the affirmative vote of two-thirds of our voting stock that is not beneficially owned by the affiliated shareholder at a meeting of shareholders
called for that purpose within six months after the affiliated shareholder’s acquiring the shares. Although we may elect to exclude ourselves from the
restrictions imposed by Section 21.606, our articles of incorporation does not do so.

Certain Provisions of Our Articles of Incorporation and Bylaws

Some provisions of our articles of incorporation and bylaws could make the acquisition of control of the Company and/or the removal of our

existing management more difficult, including those that provide as follows:

·

·

·

·

·

cumulative voting in the election of our Board of Directors, which would otherwise allow holders of less than a majority of our shares to elect
director candidates, is prohibited under our articles of incorporation;

our  Board of Directors may amend or repeal our bylaws, or adopt new bylaws without shareholder approval;

our Board of Directors can increase or decrease the size of the Board without shareholder approval by amending the bylaws;

shareholder action that is not taken at a regular or special meeting of our shareholders may only be taken by the unanimous written consent of our
shareholders; and

our Board of Directors is authorized to issue shares of our preferred stock without shareholder approval.

These provisions may be expected to discourage coercive takeover practices and inadequate takeover bids. They may also encourage persons
seeking to acquire control of the Company to first negotiate with our Board of Directors. We believe that the benefits of our increased protection give us
the potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure us, and that these benefits outweigh
the disadvantages of discouraging the proposals. Negotiating with the proponent could result in an improvement of the terms of the proposal.

Stock Exchange Listing

Our common stock is traded on the Nasdaq Stock Market under the symbol “USLM.”

Transfer Agent and Registrar

Our transfer agent and registrar is Computershare Investor Services, P.O. Box 30170, College Station, TX 77842.

MINE SAFETY DISCLOSURES

EXHIBIT 95.1

The following disclosures are provided pursuant to Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer
Protection Act and Item 104 of SEC Regulation S-K, which requires certain disclosures by companies required to file periodic reports under
the Securities Exchange Act of 1934, as amended, that operate mines regulated under the Federal Mine Safety and Health Act of 1977 (the
“Mine Act”).

The Mine Act has been construed as authorizing MSHA to issue citations and orders pursuant to the legal doctrine of strict

liability, or liability without fault. If, in the opinion of an MSHA inspector, a condition that violates the Mine Act or regulations
promulgated pursuant to it exists, then a citation or order will be issued regardless of whether the operator had any knowledge of, or fault
in, the existence of that condition. Many of the Mine Act standards include one or more subjective elements, so that issuance of a citation
or order often depends on the opinions or experience of the MSHA inspector involved, and the frequency and severity of citations and
orders will vary from inspector to inspector.

Whenever MSHA believes that a violation of the Mine Act, any health or safety standard, or any regulation has occurred, it may

issue a citation or order which describes the violation and fixes a time within which the operator must abate the violation. In some
situations, such as when MSHA believes that conditions pose a hazard to miners, MSHA may issue an order requiring cessation of
operations, or removal of miners from the area of the mine, affected by the condition until the hazards are corrected. Whenever MSHA
issues a citation or order, it has authority to propose a civil penalty or fine, as a result of the violation, that the operator is ordered to pay.

The table that follows reflects citations, orders, violations and proposed assessments issued to the Company by MSHA during

the year ended December 31, 2019 and any pending legal actions as of December 31, 2019. Due to timing and other factors, the data may not
agree with the mine data retrieval system maintained by MSHA. The proposed assessments for the year ended December 31, 2019 were
taken from the MSHA system as of February 27,  2020.

Additional information follows about MSHA references used in the table:

·

·

·

·

·

Section 104(a) Citations:  The total number of citations received from MSHA under section 104(a) of the Mine Act for
alleged violations of health or safety standards that could significantly and substantially contribute to a serious injury if left
unabated.
Section 104(b) Orders:  The total number of orders issued by MSHA under section 104(b) of the Mine Act, which represents
a failure to abate a citation under section 104(a) within the period of time prescribed by MSHA. This results in an order of
immediate withdrawal from the area of the mine affected by the condition until MSHA determines that the violation has been
abated.
Section 104(d) Citations and Orders:  The total number of citations and orders issued by MSHA under section 104(d) of the
Mine Act for unwarrantable failure to comply with mandatory health or safety standards.
Section 110(b)(2) Violations:  The total number of flagrant violations issued by MSHA under section 110(b)(2) of the Mine
Act.
Section 107(a) Orders:  The total number of orders issued by MSHA under section 107(a) of the Mine Act for situations in
which MSHA determined an imminent danger existed.

Citations and orders can be contested before the Federal Mine Safety and Health Review Commission (the “Commission”), and as

part of that process, are often reduced in severity and amount, and are sometimes dismissed. The Commission is an independent
adjudicative agency that provides administrative trial and appellate review of legal disputes arising under the Mine Act. These cases may
involve, among other questions, challenges by operators to citations, orders and penalties they have received from MSHA, or complaints
of discrimination by miners under section 105 of the Mine Act.

(1) The definition of a mine under section 3 of the Mine Act includes the mine, as well as other items used in, or to be used in, or resulting
from, the work of extracting and processing limestone, such as roads, land, structures, facilities, equipment, machines, tools, kilns, and
other property. These other items associated with a single mine have been aggregated in the totals for that mine.

(2) The proposed MSHA assessments issued during the reporting period do not necessarily relate to the citations or orders issued by

MSHA during the reporting period or to any pending contests reported above.

(3)

Includes any pending legal action before the Commission involving such mine as of December 31, 2019. Any pending legal actions
were initiated by the Company and may include multiple citations or orders. The pending legal actions may relate to the citations or
orders issued by MSHA during the reporting period or to citations or orders issued in prior periods. There was one legal action
resolved and one instituted during the reporting period.

Pattern or Potential Pattern of Violations.  During the year ended December 31, 2019, none of the mines operated by the
Company received written notice from MSHA of either (a) a pattern of violations of mandatory health or safety standards that are of such
nature as could have significantly and substantially contributed to mine health or safety hazards under section 104(e) of the Mine Act or
(b) the potential to have such a pattern.
