ITEM 1. BUSINESS.

General.

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 have been recast to be consistent with the 2019 and 2020 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”).

On July 1, 2020, the Company acquired ART Quarry TRS LLC (DBA Carthage Crushed Limestone) (“Carthage”), a limestone mining and production company located in Carthage, Missouri, for $8.4 million cash, subject to adjustment for working capital balances acquired. Carthage provides aggregate and pulverized limestone products that are used primarily in the agricultural, construction, roofing and industrial industries.

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), metals (including steel producers), environmental (including municipal sanitation and water treatment facilities and flue gas treatment processes), roof shingle manufacturers, agriculture (including poultry and cattle feed producers), and oil and gas services industries. The Company is headquartered in Dallas, Texas and operates lime and limestone plants and distribution facilities in Arkansas, Colorado, Louisiana, Missouri, Oklahoma and Texas through its wholly owned subsidiaries, Arkansas Lime Company, ART Quarry TRS LLC (DBA Carthage Crushed Limestone), 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, aggregate, 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 2020, 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 ten 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.

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), metals producers (including steel producers), environmental customers (including municipal sanitation and water treatment facilities and flue gas treatment processes), roof shingle manufacturers, poultry and cattle feed producers, and oil and gas services companies.

Approximately 630 customers accounted for the Company’s sales of lime and limestone products during 2020. 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 within our geographic region and by 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 2020 sales were made within the United States.

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. Carthage extracts limestone from an underground mine located in Carthage, Missouri. 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, St. Clair, and Carthage, 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, 2020, were approximately 27 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, 2020, 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, 2020, were approximately 76 million tons of probable recoverable reserves. The Company is improving the transportation infrastructure between the Love Hollow Quarry and Arkansas Lime’s production facilities and incurring other development costs to prepare the Love Hollow Quarry for mining. Assuming the current level of

2

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.

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, 2020, 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.

Carthage operates an underground mine and has limestone production facilities located on approximately 800 acres that it owns containing high-quality limestone reserves. In addition, Carthage has the right to mine the high-quality limestone contained in approximately 160 adjacent acres pursuant to long-term mineral leases. The owned and leased reserves, as of December 31, 2020, were approximately 14 million tons of probable recoverable reserves. 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 20 years. Additionally, the Company has an option to acquire the right to mine under long-term mineral leases on approximately 600 acres of adjacent land. The Company is drilling and assessing the quality of the reserves on the properties with options to lease.

During 2020, the Company produced approximately 3 million tons of limestone from its quarries and mines.

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 and Carthage underground mines, 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, St. Clair and Carthage 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

3

Company-owned railroad. The PLS equipment, depending on the product mix, has the capacity to produce approximately 300 thousand tons of PLS annually.

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 Carthage plant has facilities located next to the mine that produce both aggregates and PLS. The equipment has the capacity to produce approximately 900 thousand tons 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 2020, the Company’s utilization rate was approximately 57% 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.

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.

Human Capital Resources. The Company is committed to attracting and retaining the best and brightest talent to meet the current and future needs of its business. Attracting, retaining, motivating, and investing in the development of human capital resources is a critical part of the Company’s commitment to environmental, social, and governance (“ESG”) and sustainability issues.

At December 31, 2020, the Company employed 317 persons, 110 of whom were represented by unions. The Company is a party to three collective bargaining agreements. The collective bargaining agreement for the Texas facilities expires in November 2023. The collective bargaining agreement for the Arkansas facilities expires in January 2023. The collective bargaining agreement for the Carthage facilities expires in May 2022. Overall, the Company believes that its employee relations are generally good.

Employee Retention and Incentivization. The Company has entered into an employment agreement with Timothy W. Byrne, its President and Chief Executive Officer. Mr. Byrne’s employment agreement became effective as of January 1, 2020 for a five-year term and will continue for successive one-year periods unless the Company or Mr. Byrne gives at least one-year’s prior written notice of intent not to renew. Under the employment agreement, in addition to the possibility of a discretionary cash bonus, Mr. Byrne is entitled each year to an EBITDA cash bonus opportunity under the United States Lime & Minerals, Inc. Amended and Restated 2001 Long-Term Incentive Plan (the “Plan”), and he is also entitled to grants of equity awards under the Plan.

Mr. Byrne’s employment agreement provides that Mr. Byrne is subject to certain forfeiture/clawback and share ownership provisions designed to align Mr. Byrne’s financial interests with those of the Company’s long-term shareholders, and to ensure that he is incentivized not to take actions that may benefit the Company and its shareholders

in the short-term at the expense of long-term corporate value creation and sustainability. In particular, in entering into the employment agreement with Mr. Byrne, the Company’s Board of Directors and Compensation Committee were sensitive to how Mr. Byrne’s leadership and actions could further the Company’s various objectives, including human capital resources development and executive succession planning.

With respect to the Company’s broader employee base, certain employees are eligible to receive annual cash bonuses based on discretionary determinations. Except in the case of Mr. Byrne, the Company has not adopted a formal or informal annual bonus arrangement with pre-set performance goals. Rather, the determination to pay a cash bonus, if any, is made in December each year based on the past performance of the individual and the Company or on the attainment of non-quantified performance goals during the year. In either such case, the discretionary bonus may be based on the specific accomplishments of the individual and/or on the overall performance of the Company. The amounts of the discretionary bonuses for 2020 were based on each employee’s individual performance and accomplishments, as well as those of the Company, including productivity, sales, and contributions made to special projects.

In addition to cash bonuses, the Company makes equity awards to certain individuals under the Plan. The Company uses equity awards granted under the Plan as a means to attract, retain, and motivate the Company’s directors, officers, employees, and consultants. The Company views the use of equity awards under the Plan as an important means of aligning the interests of its employees with those of its shareholders.

Employee Health and Safety. The Company believes that it is responsible to its 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.

In response to the COVID-19 pandemic, the Company is continuing to focus on the health and safety of its employees and other individuals at its facilities that produce lime and limestone products to the essential businesses and communities that it serves. In addition to its standard health and safety protocols, the Company has implemented enhanced protocols at all of its locations. These protocols include reduced access to facilities, screening of individuals on all sites, and the enforcement of social distancing and other practices that are consistent with, or exceed, the guidelines of the Center for Disease Control and state and local authorities.

Employee Development and Training. The Company encourages and supports the growth and development of its employees. It advances continual learning and career development through ongoing performance and development conversations or evaluations with employees and internally and externally developed training programs. The Company also provides reimbursement for certain educational programs relating to the Company’s business.

Employee Diversity and Inclusion. The Company is committed to fostering a work environment that values and promotes diversity and inclusion. This commitment includes providing equal access to, and participation in, equal employment opportunities, programs, and services, without regard to a person’s gender, nationality, race, and ethnicity. The Company is focused on the development and fair treatment of its employees, including equal employment hiring practices and policies, anti-harassment, and anti-retaliation policies. The Company is continuing to invest in and take actions in an effort to create a more diverse and inclusive workforce and workplace environment.

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

5

Table of Contents

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, the kiln project at our St. Clair operations in Oklahoma, and the July 2020 Carthage acquisition, 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 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.

Compliance with Government Regulations. The Company is subject to various federal, state, and local laws and regulations that may materially impact the Company’s financial condition, results of operations, cash flows and competitive position. These include laws and regulations relating to the environment, mine permitting and operations, mine safety, and reclamation and remediation.

Environmental Laws. The Company owns or controls large areas of land on which it operates limestone quarries, two underground mines, 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 and reporting 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 compliance activities, and mining reclamation. Many Environmental Laws also authorize private citizens and interest groups to file lawsuits in court to enforce alleged violations. Changes in policy or political leadership may affect how Environmental Laws are interpreted or enforced by the EPA and state governmental agencies. 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

6

Table of Contents

Ambient Air Quality Standards (“NAAQS”), which are used to establish permitting limits 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 adopted a rule package in June 2020 to incorporate the 2015 ozone NAAQS into the emission inventory provisions of 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. In February 2021, the new Administration rejoined the Paris Agreement. The Agreement commits the United States to reduce greenhouse gas emissions by 26 to 28 percent below 2005 levels by 2025. Future regulation related to the Paris Agreement or other greenhouse gas rulemakings could affect New Source Review permitting or other permitting programs 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 greenhouse gas emission limits, 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 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.

In July 2020, the EPA adopted a final revision to a federal regulation that establishes national standards to meet the maximum achievable control technology (“MACT”) within the lime industry.  Also known as the “Lime MACT,” this rulemaking is the second revision to the initial Lime MACT promulgated in 2004.  The revision included changes to the startup, shutdown and malfunction provisions contained in the prior Lime MACT rule, but otherwise did not impose more stringent standards. In September 2020, a non-governmental organization filed a petition for reconsideration asking the EPA to reconsider the Lime MACT and arguing the EPA’s decision to not set limits for hazardous air pollutants was unlawful. The non-governmental organization also initiated litigation in September 2020 before the D.C. Circuit Court of Appeals to challenge the Lime MACT. It is uncertain how the petition for reconsideration, the litigation, or changes in policy and political leadership may affect the Lime MACT rulemaking.

There is no assurance that the final Lime MACT rule will not be withdrawn, revised or overturned by a judicial decision, or that a replacement regulation will not incorporate more stringent standards.  Changes in the Lime MACT rule 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 and must comply with the Clean Water Act and analogous state laws and regulations. Any failure to comply with these permits could result in fines or other penalties. Material changes to the terms of these permits or changes to regulations affecting water discharges in the future could also increase compliance costs.

The manufacturing of lime and hydrated lime requires significant volumes of 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 to pump groundwater. Any failure to comply with these permits could result in fines or other penalties and future changes that restrict the quantities of groundwater that may be pumped may increase compliance costs.

The Company incurred capital expenditures related to environmental matters of $0.7 million, $1.2 million, and $1.2 million in 2020, 2019, and 2018, 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, $0.5 million and $0.6 million in 2020, 2019 and 2018, respectively.

Mine Safety. The Company’s mining operations are also subject to regulation under the Federal Mine Safety and Health Act of 1977 (the “Mine Act”). The Mine Act has been construed as authorizing the Mine Safety and Health Administration (“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.

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.

Reclamation and Remediation. 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”). Some of the states the Company operates in have reclamation regulations to properly reclaim the surface mines. These regulations require permitting with the respective state to ensure reclamation obligations are met. 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, 2020 is reasonable.

Other.

Our Other operations, consisting of our natural gas interests, 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, 2020, 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, 2020, 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. The carrying values of the long-lived assets related to our natural gas interests were $2.0 million as of December 31, 2020.

ITEM 1A. RISK FACTORS.

COVID-19 Risks

Our financial condition, results of operations, cash flows, and competitive position could be materially adversely impacted by the COVID-19 pandemic.  The extent to which COVID-19, and measures taken in response thereto, could materially adversely affect our financial condition, results of operations, cash flows and competitive position will depend on future developments, which are highly uncertain and cannot be predicted, including the scope and duration of the pandemic and actions taken by governmental authorities, including the effectiveness and administration of vaccines, to contain the business, financial and economic impact of the pandemic.

 

While we are continuing to execute our business continuity plans in response to the COVID-19 pandemic, there is the potential for increased disruptions to our lime and limestone business and operations from the pandemic.  Federal, state, and local governmental responses to the COVID-19 pandemic, which include restrictions requiring social distancing and pandemic-related restrictions on business activities and movement of people in the markets for our lime and limestone products, began to take effect the last two weeks of March 2020. In the second quarter 2020, the pandemic and related restrictions on business activities resulted in a general economic slowdown, which has disproportionately impacted certain industries that purchase our lime and limestone products, including oil and gas services, environmental and steel. In the third quarter 2020, business activity began to resume, and restrictions were eased. In the fourth quarter 2020, we saw demand return from certain industries, most notably our environmental and steel customers, after being down the previous quarters. However, the United States has seen multiple surges of COVID-19 cases in the fourth quarter 2020 and the first quarter 2021, which could impact the economic recovery that has occurred to date. Until there are successful implementations of COVID-19 vaccination programs, we expect a continued slowdown in economic activity as restrictions continue, or even expand, which we anticipate will have an adverse impact on the demand for our lime and limestone products and increase our costs. In addition, a continued economic slowdown may put downward pressure on the prices we are able to realize for our products.

The continued impact of COVID-19 may limit our ability to produce, sell and deliver our lime and limestone products to our customers; cause key management and plant-level employees not to be available to us; result in plant shutdowns due to contagion, in which case we may not be able to shift production to our other plants; cause disruptions to our supply chain as it relates to our suppliers and other vendors, as well as disrupt the supply chains of our customers; impede our ability to maintain and repair our plants and equipment; negatively impact our modernization, expansion, and development plans; negatively impact our ability to integrate acquisitions; as well as adversely impact demand and prices for our lime and limestone products and increase our costs.  Although we cannot predict future developments, which are highly uncertain, including the scope and duration of the pandemic, the effectiveness of vaccines, and actions taken by governmental authorities, including the effective administration of vaccination programs, to contain the pandemic, COVID-19 could have a material adverse effect on our financial condition, results of operations, cash flows and competitive position.

Industry Risks

Our Lime and Limestone Operations are affected by general economic conditions in the U.S. and specific economic 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. Our steel and oil and gas services customers reduce 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.

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.

10

Table of Contents

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, such as the February 2021 winter storms in the southern United States, 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.

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.

Business and Financial Risks

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 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, including the facilities acquired as a result of the Carthage acquisition, 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 changes to Department of Transportation rules and regulations can reduce the

11

Table of Contents

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.

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.

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 our ability to insure against certain risk of our operations.

Mining limestone and producing lime and limestone products involves risks which could result in damage to our facilities, personal injury, and environmental damage. Although we maintain insurance in an amount that we consider adequate, liabilities might exceed policy limits, in which event we could incur significant costs that could adversely affect our financial position, results of operations, cash flows and competitive position. Additionally, the risks inherent in mining limestone and the production of lime and limestone products may significantly increase the cost of obtaining adequate insurance coverage, or make some coverage unavailable.

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, encryption by ransomware, or may result from 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, competitive position, and

12

Table of Contents

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.

Governmental, Legal and Regulatory Risks

Our Lime and Limestone Operations are subject to general and industry specific regulations. Changes to the regulatory environment could increase our cost of compliance and adversely impact our financial condition, results of operations, cash flows and competitive position.

We are in a period of regulatory uncertainty, which has been heightened by the change in the United States federal government Administration and Congress. The new Administration and Congress may initiate actions to increase regulation of certain industries, including the lime industry, and may take other steps to restrict oil and gas drilling, reduce the use of coal or regulate domestic manufacturing. There can be no assurance that any of these actions, if adopted, will not increase the costs for our customers or increase the Company’s cost of compliance with Environmental Laws. In addition, a variety of factors, including uncertainty with respect to governmental budgetary constraints, legislative impasses, extended government shutdowns, pandemics, trade wars, tariffs, social unrest, and increased inflationary pressures, could have a material adverse effect on our financial condition, results of operations, cash flows and competitive position.

Governmental fiscal and budgetary constraints, changes to tax law, 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, changes to tax law, 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.

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, such as 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. Changes in policy or political leadership may affect how Environmental Laws are interpreted or enforced by the EPA and state governmental agencies. The new Administration has signaled its intent to increase regulation under Environmental Laws and has issued multiple executive orders reversing prior deregulation. 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. In February 2021, the new Administration rejoined the Paris Agreement, under which the United States committed to reduce greenhouse gas emissions. 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 companies to purchase carbon credits, the imposition of greenhouse gas emission limits 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

13

Table of Contents

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, 2020 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.

Our lime and limestone operations are subject to various regulatory risks, including those relating to mine safety, and reclamation and remediation obligations.

Our mining operations are subject to mine safety regulation under 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. Citations and orders can be contested before the Commission, and as part of that process, are often reduced in severity and amount, and are sometimes dismissed.

We also have legal reclamation and remediation obligations associated with the retirement of 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, we either settle the ARO for its recorded amount or recognize a gain or loss. We believe our accrual for AROs is reasonable, but there can be no assurance that any amounts accrued will be sufficient to meet our reclamation and remediation obligations at any point in time.

We intend to comply with all mining regulations and all of our reclamation and remediation obligations. Our failure to comply with such regulations and obligations may adversely impact our financial condition, results of operations, cash flows and competitive position.

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. While we may 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.

On July 1, 2020, we acquired Carthage, a limestone mining and production company located in Carthage, Missouri, for $8.4 million cash, subject to adjustment for working capital balances acquired. Carthage provides aggregate and pulverized limestone products that are used primarily in the agricultural, construction, roofing and industrial industries. Carthage’s assets and liabilities are included on our December 31, 2020 balance sheet at fair values, with $7.5 million allocated to property, plant and equipment. Carthage contributed $4.6 million to our revenues in 2020. We believe that this acquisition complements our existing geographic footprint.

In the fourth quarters 2020 and 2019, we recognized impairment charges of $1.6 million ($1.2 million, net of tax) and $0.9 million ($0.7 million, net of tax), respectively, related to our natural gas interests. Continuing low prices for natural gas and natural gas liquids have reduced the estimates for future economically feasible production from our

Table of Contents

drilled wells, which has impaired the recoverability of the assets as they approach the end of their useful lives. The carrying values of the long-lived assets related to our natural gas interests were $2.0 million as of December 31, 2020.  

Revenues increased 1.5% in 2020 compared to 2019. Revenues from our Lime and Limestone Operations increased 1.7% in 2020, compared to 2019, primarily due to the addition of limestone sales by Carthage to agriculture and roofing customers, and increased sales to the Company’s construction customers, partially offset by decreased demand from the Company’s oil and gas services, environmental and steel customers. Revenues in 2020 were also favorably impacted by an increase in average selling prices for our lime and limestone products of 3.6%.

Gross profit increased 14.2% in 2020 compared to 2019. Gross profit from our Lime and Limestone Operations in 2020 increased 14.1%, compared to 2019, primarily due to increases in the average selling prices for our lime and limestone products, lower fuel costs, and increased operating efficiencies associated, in part, with our new, fuel-efficient kiln at our St. Clair facility, which began producing commercially saleable quicklime in the second quarter 2019, partially offset by increased costs incurred in 2020 associated with responding to the COVID-19 pandemic.

Interest expense remained flat at $0.2 million for each of 2020 and 2019. Interest and other income, net, decreased $1.4 million in 2020, or 76.2%, compared to 2019, primarily due to decreased interest rates received on our cash and cash equivalents balances in 2020.

Net income increased $2.2 million, or 8.3%, in 2020, compared to 2019. Net income per fully diluted share increased to $5.00 in 2020, compared to $4.64 in 2019. Cash flows from operations enabled us to make $17.1 million of capital investments, including our acquisition of Carthage for $8.4 million. It also enabled us to pay $3.6 million in dividends and increase our cash balances to $83.6 million as of December 31, 2020, compared to $54.3 million as of December 31, 2019. As of December 31, 2020, we had no debt outstanding.

On January 29, 2021, we announced that our Board of Directors had declared a regular quarterly cash dividend of $0.16 (16 cents) per share. The dividend is payable on March 12, 2021 to shareholders of record on February 19, 2021.

Absent a significant acquisition opportunity arising during 2021, we anticipate funding our operating and capital needs and our 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, aggregate, 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 customers increased in 2020. However, demand for our lime and limestone products from our oil and gas services, environmental and steel customers decreased. Oil prices declined sharply in 2020 compared to 2019, which resulted in a curtailment of drilling activities during 2020 and lower demand from our oil and gas services customers.

The emergence of COVID-19 in the United States in the first quarter 2020 created significant volatility, uncertainty and economic disruption to the general business environment. Federal, state, and local governmental responses to the COVID-19 pandemic, which include restrictions requiring social distancing and restrictions on business activities and movement of people in the markets for our lime and limestone products, began to take effect the last two

19

Table of Contents

weeks of March 2020 and continue in effect in many of the Company’s markets. In the second quarter 2020, the pandemic and related restrictions on business activities resulted in a general economic slowdown, which has disproportionately impacted certain industries that purchase our lime and limestone products, including oil and gas services mentioned above, environmental and steel. Late in 2020, we saw indications that demand from our environmental and steel customers was returning, however, multiple recent surges of COVID-19 cases could impact the renewed demand from such customers and the economic recovery that has occurred to date. Until there are successful implementations of COVID-19 vaccination programs, we expect a continued slowdown in economic activity as restrictions continue or even expand, which we anticipate may continue to have an adverse impact on the demand for our lime and limestone products, particularly with respect to our customers in certain industries, and put downward pressure on the prices that we are able to realize for our products, as well as increase our costs.

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. Through November 2020, the Texas State Highway Fund received approximately $15.7 billion in revenues from these two amendments. With these State funding improvements, along with the focus on infrastructure investment proposed by the new federal 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, political, 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 kiln at St. Clair, which began producing commercially saleable quicklime in the second quarter 2019, 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, including the facilities acquired as a result of the Carthage acquisition, 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 to our customers, where possible, through higher prices and/or surcharges on certain products. In addition, as noted above, we put a 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.

Table of Contents

We continue to believe the enhanced efficiency and production capacity resulting from our modernization and expansion and development projects in Texas, Arkansas, and Oklahoma, our expanded slurry operations, our acquisitions, including the recent acquisition of Carthage, 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, taxes or new environmental, health and safety or 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 2020 included $1.0 million from our natural gas interests, compared to $1.3 million and $2.5 million in 2019 and 2018, respectively. Gross profit (loss) in 2020 included a loss of $(0.4) million from our natural gas interests, compared to a loss of $(0.4) million in 2019 and profit of $1.0 million in 2018.  Impairment charges relating to our natural gas interests of $1.6 million and $0.9 million in 2020 and 2019, respectively, adversely impacted our operating profit. The impairment charges are included with other operating profit (loss) in our segment disclosures. See Note 11 to the Notes to the Consolidated Financial Statements.

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 $28.4 million, $28.4 million and $25.6 million for 2020, 2019 and 2018, 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. The majority of our trade accounts receivable are unsecured. Payment terms for all trade receivables are based on the underlying purchase orders, contracts, or purchase agreements. We estimate credit losses relating to trade receivables based on an assessment of the current and forecasted probability of collection, historical trends, economic conditions, and other significant events that may impact the collectability of accounts receivables. Due to the relatively homogenous nature of its trade receivables, the Company does not believe there is any meaningful asset-specific differences within its accounts receivable portfolio that would require the portfolio to be grouped below the

21

Table of Contents

consolidated level for review of credit losses. 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. The Company maintains an allowance for credit losses to reflect currently expected estimated losses resulting from the failure of customers to make required payments. A considerable amount of judgment is required in assessing the ultimate realization of these receivables and determining our allowance for doubtful accounts.

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.

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 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 2020 and 2019, we recognized impairment charges of $1.6 million and $0.9 million, respectively, to adjust the carrying value of certain long-lived assets related to our natural gas interests.

Environmental costs and liabilities. We record environmental accruals, including accrued reclamation costs, 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.

2020 vs. 2019

Revenues for 2020 increased to $160.7 million from $158.3 million in 2019, an increase of $2.4 million, or 1.5%. Revenues from our Lime and Limestone Operations in 2020 increased $2.7 million, or 1.7%, to $159.7 million from $157.0 million in 2019. The increase in revenues from our Lime and Limestone Operations was primarily due to the addition of limestone sales by Carthage to agriculture and roofing customers and increased sales volumes of our lime and limestone products, principally to our construction customers, partially offset by decreased demand from our oil and gas services, environmental and steel customers. In addition, we realized a 3.6% average increase in prices for our lime and limestone products in 2020, compared to 2019. Other revenues included $1.0 million and $1.3 million in 2020 and 2019, respectively, from our natural gas interests.

Our gross profit increased to $47.6 million for 2020 from $41.7 million for 2019, an increase of $5.9 million, or 14.2%. Gross profit from our Lime and Limestone Operations for 2020 was $48.0 million, compared to $42.0 million in 2019, an increase of $5.9 million, or 14.1%. The increase in gross profit in 2020, compared to 2019, resulted primarily from increases in the average selling prices for the Company’s lime and limestone products, lower fuel costs and increased operating efficiencies associated, in part, with the kiln at the Company’s St. Clair facility, which began producing commercially saleable quicklime in the second quarter 2019, partially offset by increased costs incurred in the 2020 periods associated with responding to the COVID-19 pandemic. Gross profit also included the impact of a $(0.4) loss in each of 2020 and 2019 from our natural gas interests.

Selling, general and administrative expenses (“SG&A”) increased to $12.2 million for 2020, an increase of $0.7 million, or 5.8%, compared to $11.5 million for 2019. As a percentage of revenues, SG&A was 7.6% for 2020, compared to 7.3% in 2019. The increase in SG&A was primarily due to increased personnel expenses, including stock-based compensation which was principally due to higher prices for the Company’s common stock, and increased legal expenses and COVID-19 pandemic costs in the second quarter 2020.

In the fourth quarters 2020 and 2019, we recognized an impairment charge of $1.6 million ($1.2 million, net of tax) and $0.9 million ($0.7 million, net of tax), respectively. Continuing low prices for natural gas and natural gas liquids have reduced the estimates for future economically feasible production, which has impaired the recoverability of the

assets as they approach the end of their useful lives. The carrying values of the long-lived assets of the Company’s natural gas interests were $2.0 million at December 31, 2020

Interest expense was $0.2 million in each of 2020 and 2019, as we had no outstanding debt during either 2020 or 2019.

Interest and other income, net was $0.5 million in 2020, compared to $1.9 million in 2019. The decrease in interest and other income, net in 2020, compared to 2019, was primarily due to decreased interest rates received on cash and cash equivalents balances in 2020.

Income tax expense was $5.8 million in 2020, for an effective rate of 17.2%, compared to $4.8 million in 2019, for an effective rate of 15.7%, an increase of $1.0 million, primarily due to the increase in income before taxes in 2020, compared to 2019. Our effective income tax rates for 2020 and 2019 were reduced from the statutory rate primarily due to statutory depletion in excess of cost depletion. In addition, for 2019, our effective tax rate was reduced as a result of research and development tax credits.

Net income increased to $28.2 million ($5.00 per share diluted) in 2020, compared to $26.1 million ($4.64 per share diluted) in 2019, an increase of $2.2 million, or 8.3%.

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. Other revenues 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 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.

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.

Table of Contents

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%.

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.

We expect to spend approximately $14.0 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, 2020, we had $5.0 million in open orders or contractual commitments for our Lime and Limestone Operations.

Liquidity and Capital Resources. Net cash provided by operating activities was $58.6 million in 2020, compared to $47.0 million in 2019, an increase of $11.6 million, or 24.6%. 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 2020, net cash provided by operating activities was principally composed of $28.2 million net income, $19.6 million DD&A, $4.3 million increase in deferred income taxes, $1.6 million impairment of long-lived assets, $1.9 million stock-based compensation, and a $2.5 million increase from changes in working capital. In 2020, the changes in working capital were principally composed of a $2.9 million increase in accounts payable, accrued expense and other liabilities, and a $1.1 million decrease in trade receivables, net, partially offset by a $1.4 million increase in inventories. 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.

Net cash used in investing activities was $25.2 million for 2020, compared to $26.5 million for 2019. Net cash used in investing activities included $8.4 million for the acquisition of Carthage and $17.1 million for the purchase of property, plant and equipment for 2020, including $2.7 million for the Carthage location and $2.1 million for specialized equipment at the Batesville Quarry. Net cash used in investing activities for 2019 was primarily $27.1 million for the purchase of property, plant and equipment. Net cash used in investing activities in 2019 included $8.0 million for specialized equipment at the Batesville Quarry, $5.6 million for the St. Clair kiln project, and $2.8 million for a new slurry terminal in the Dallas-Fort Worth area. The balance of net cash used in investing activities in 2020 and 2019 was primarily for normal recurring capital and re-equipping projects at our plants and facilities.

Net cash used in financing activities primarily consisted of $3.6 million for dividend payments and $0.6 million to repurchase shares of our common stock in 2020, compared to $33.1 million for dividend payments in 2019, including a special cash dividend of $30.0 million, and $0.4 million to repurchase shares of our common stock.

Our cash and cash equivalents at December 31, 2020 increased to $83.6 million from $54.3 million at December 31, 2019.

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

Table of Contents

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 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, 2020 or 2019. We had $0.4 million of letters of credit issued under the Revolving Facility as of December 31, 2020, which count as draws against the available commitment under the Revolving Facility.

Common Stock Buybacks. We spent $0.6 million, $0.4 million and $0.4 million in 2020, 2019 and 2018, respectively, to repurchase treasury shares tendered for payment of the exercise price for stock options and the tax withholding liability upon the lapse of restrictions on restricted stock.

Contractual Obligations. The following table sets forth our contractual obligations as of December 31, 2020 (in thousands):

(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, $380 were recorded on the Consolidated Balance Sheet at December 31, 2020.
(3)Purchase obligations includes enforceable agreements to purchase goods or services that specify all significant terms, including fixed or minimum quantities to be purchased, generally pertaining to fuel contracts, fixed-price provisions, and the approximate timing of the transaction, and are either non-cancelable or subject to significant penalty upon cancellation.

Absent a significant acquisition, 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, 2020, the total future lease payments under our various operating and limestone mineral leases totaled $2.3 million and $1.8 million, respectively, and are due in payments as summarized in the table above.

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, 2020. Any future borrowings under the Revolving Facility would be subject to interest rate risk. See Note 3 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, 2020 and 2019, the related consolidated statements of income, comprehensive income, changes in stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2020, 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, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020, 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, 2020, 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 26, 2021 expressed an unqualified opinion.

Table of Contents

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the 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, 2020, 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, 2020, 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, 2020, and our report dated February 26, 2021 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.
