General.

United States Lime & Minerals, Inc. (the “Company,” the “Registrant,” “We” or “Our”), which was incorporated in 1950, conducts its business primarily through two segments,its Lime and Limestone Operations and Natural Gas Interests.segment. The Company’s Other operations relate to its natural gas interests.

The Company’s principal corporate office is located at 5429 LBJ Freeway, Suite 230, Dallas, Texas 75240. The Company’s telephone number is (972) 991‑8400991-8400 and its internet address is www.uslm.com. The Company’s annual reports on Form 10‑K,10-K, quarterly reports on Form 10‑Q,10-Q, current reports on Form 8‑K8-K and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), as well as the Company’s definitive proxy statement filed pursuant to Section 14(a) of the Exchange Act, are available free of charge on the Company’s website as soon as reasonably practicable after the Company electronically files such material with, or furnishes it to, the Securities and Exchange Commission (the “SEC”).

Lime and Limestone Operations.

Business and Products. The Company, through its Lime and Limestone Operations, is a manufacturer of lime and limestone products, supplying primarily the construction (including highway, road and building contractors), industrial (including paper and glass manufacturers), metals (including steel producers), environmental (including municipal sanitation and water treatment facilities and flue gas treatment processes), metalsroof shingle manufacturers, agriculture (including steelpoultry producers), and oil and gas services roof shingle and agriculture (including poultry and cattle feed producers) industries. The Company is headquartered in Dallas, Texas and operates lime and limestone plants and distribution facilities in Arkansas, Colorado, Louisiana, Missouri, Oklahoma and Texas through its wholly owned subsidiaries, Arkansas Lime Company, ART Quarry TRS LLC (DBA Carthage Crushed Limestone), Colorado Lime Company, Mill Creek Dolomite, LLC, Texas Lime Company, U.S. Lime Company, U.S. Lime Company—Shreveport,Company-Shreveport, U.S. Lime Company—St.Company-St. Clair and U.S. Lime Company—Transportation.Company-Transportation.

The Company extracts high‑qualityhigh-quality limestone from its open‑pitopen-pit quarries and an underground minemines 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‑strippinganti-stripping agent, as a conditioning agent for oil and gas drilling mud in the production of chemicals and in the production of construction materials such as stucco, plaster and mortar.chemicals. Lime slurry is used primarily in soil stabilization for highway, road and building construction.

Product Sales. In 2017,2022, the Company sold almost all of its lime and limestone products in the states of Arkansas, Arizona, Colorado, Illinois, Indiana, Iowa, Kansas, Louisiana, Mississippi, Missouri, New Mexico, Oklahoma, Tennessee and Texas. Sales were made primarily by the Company’s nineten sales employees who call on current and potential customers and solicit orders, which are generally made on a purchase‑orderpurchase-order basis. The Company also receives orders in response to bids that it prepares and submits to current and potential customers.

During 2017, the strongest demand for the Company’s lime and limestone products was from construction customers, industrial customers, environmental customers, metals producers, oil and gas services companies and roof shingle manufacturers.companies.

Approximately 600650 customers accounted for the Company’s sales of lime and limestone products during 2017.2022. No single customer accounted for more than 10% of such sales. The Company is generally not subject to significant customer demand and credit risks as its customers are considerably diversified as towithin our geographic locationregion 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 volumevolumes, prices, and prices.costs.

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 2017Company’s 2022 sales were made within the United States.

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

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

Limestone Mineral Resources and Reserves. The Company’s limestone mineral resources and reserves contain at least 96% calcium carbonate (CaCO3). The Company has twothree subsidiaries that extract limestone from open‑pitopen-pit quarries: Texas Lime Company (“Texas Lime”), which is located near Cleburne, Texas andTexas; Arkansas Lime Company (“Arkansas Lime”), which is located near Batesville, Arkansas.Arkansas; and Mill Creek Dolomite, LLC (“Mill Creek”), which the Company acquired on February 9, 2022, located near Mill Creek, Oklahoma. U.S. Lime Company—St.Company-St. Clair (“St. Clair”) extracts limestone from an underground mine located near Marble City, Oklahoma. Carthage Crushed Limestone (“Carthage”) extracts limestone from an underground mine located in Carthage, Missouri. Colorado Lime Company (“Colorado Lime”) owns property containing limestone deposits at Monarch Pass, located 15 miles west of Salida, Colorado. Existing crushed stone stockpiles on the property are being used to provide feedstock to the Company’s plantsplant in Salida and Delta, Colorado. Access to all properties is provided by paved roads and, in the case of Arkansas Lime, and St. Clair, Carthage, and Mill Creek, also by rail. The Company mined approximately 4 million tons of limestone from its quarries and mines during the year ended December 31, 2022, and approximately 3 million tons of limestone during each of the years ended December 31, 2021 and 2020.

Texas Lime operates a quarry, located on approximately 3,450 acresThe Company engaged SYB Group, LLC (“SYB”) to serve as the Qualified Person (“QP”) to prepare estimates of land that contains known high‑qualitythe 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 Limeresources and reserves, as of December 31, 2017,2021, at all of its properties except for Carthage, Mill Creek, and Colorado Lime. The QP was not retained to prepare estimates at those locations because the Company has not completed a drilling program sufficient to enable the QP to prepare estimates of the limestone mineral resources and reserves at those properties. As of December 31, 2022, the QP assessed the underlying material assumptions and information set forth in the technical report summaries for the Texas Lime Quarry, the Batesville Quarry, the Love Hollow Quarry, and the St. Clair Mine, including assumptions related to modifying factors, price estimates, and scientific and technical information. During 2022, no new drilling programs were instituted at the locations covered by the QP’s technical report summaries as of December 31, 2021. Resources and reserves were calculated using an $11.05 per ton price assumption based on the U.S. Geological Survey Mineral Commodity Summaries 2021. The U.S. Geological Survey Mineral Commodity Summaries 2022 increased the price to $12.70 per ton, but the QP has determined that the change in price did not have a material impact on the calculation of the reserves and resources and that all material assumptions and information remained current as of December 31, 2022.

Summaries of the Company’s total limestone mineral resources and reserves for all properties other than Carthage, Mill Creek, and Colorado Lime as of December 31, 2022 and 2021 are shown below. The terms “Mineral Resource”, “Measured Resources”, “Indicated Resources”, “Mineral Reserves”, “Proven Reserves” and “Probable Reserves” are defined in accordance with SEC Regulation S-K subpart 229.1300 governing disclosures by registrants engaged in mining operations. Limestone mineral reserves are included in limestone mineral resources, net of any mining loss factors.

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‑qualityhigh-quality calcium limestone and dolomite. Assuming

Internal Controls Over Limestone Mineral Resources and Reserves Estimates. Internal control procedures followed by the current levelCompany’s Quality Control/Quality Assurance Laboratories (“QC/QA Lab”) and its contract geologists when assessing properties for limestone mineral resources and reserves estimates are clearly defined. Core drilling is conducted under the direct supervision of productionthe geologists, and all core data is maintained,logged using a standard protocol. The geologists are responsible for examining the Company estimates thatcore and compiling an interval list for X-Ray Florescence (“XRF”) analysis. Splits of cores are bagged and labeled with the depth interval to be analyzed, with the remaining crushed stone stockpiles onsplit boxed and stored for reference. Bagged intervals are submitted to the property are sufficientCompany’s certified QC/QA Lab for XRF analysis, with any samples not destroyed by the testing process retained at the Company’s core storage facility. On an ongoing basis, the QC/QA Labs analyze production samples for cutoff grade consistency with expectations used in the estimates for limestone mineral resources and reserves.

Quarrying and Mining. The Company extracts limestone by the open‑pitopen-pit method at its Texas, Batesville, Mill Creek, and Arkansas quarries.Love Hollow Quarries. The Monarch Pass Quarry is also an open‑pitopen-pit quarry but is not being mined at this time. The open‑pitopen-pit method consists of removing any overburden comprising soil and other substances, including inferior limestone, and then extracting the exposed high‑qualityhigh-quality limestone. The Company removes such overburden by utilizing both its own employees and equipment and those of outside contractors. Open‑pitOpen-pit mining is generally less expensive than underground mining. The principal disadvantage of the open‑pitopen-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 mine,mines, the Company mines limestone using room and pillar mining. The Company hasWe have no knowledge of any recent changes in the physical quarrying or mining conditions on any of itsour properties that have materially affected its 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 fivefour plants, six lime slurry facilities and twothree terminal facilities. All of its plants and facilities are accessible by paved roads, and, in the case of the Arkansas Lime, and 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 Lime 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. The Arkansas Lime plant is approximately 21 miles from the Love Hollow Quarry, to which it is connected by railroad. Arkansas Lime’s PLS and hydrating facilities are situated on a tract of 290 acres located approximately two miles from the Batesville Quarry, to which it is connected by a Company‑ownedCompany-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 180250 thousand tons of quicklime from twoone vertical kiln and one preheater rotary kilns, one of which is not a preheater kiln. The plant also has PLS equipment, which has the capacity to produce approximately 150 thousand tons of PLS annually. In

The Carthage plant has facilities located next to the fourth quarter 2013,mine that produce both aggregates and PLS. The equipment has the Company received the necessary air permit from the Oklahoma Department of Environmental Qualitycapacity to replace the non‑preheater kiln with the construction of a new, more fuel‑efficient vertical kiln.  The Company has begun construction on the new kiln and related plant improvements, which it estimates will costproduce approximately $50 million.  In October 2016, the Company entered into900 thousand tons annually.

The equipment has the Company has incurredcapacity to produce approximately $14.3 million and had outstanding purchase obligations of approximately $14.7 million.  The Company expects the new kiln should be completed near the end of 2018.300 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, and Mill Creek 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‑halfone-half acres of land in Delta, Colorado, and a limestone drying, grinding and bagging facility, with an annual capacity of approximately 40 thousand tons, located on eight acres of land in Salida, Colorado. The Salida property is leased from the Union Pacific Railroad for a five‑year term ending June 2019.

During 2017,2022, the Company’s utilization rate was approximately 63%70% of its aggregate approximate 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 threefour Houston area facilities, including a newtwo distribution terminal, which isterminals connected to a railroad, established in 2015 southwest of Houston, Texas,railroads, to serve the Greater Houston area construction market and threefour facilities to serve the Dallas‑Ft.Dallas-Ft. Worth Metroplex. The Company established U.S. Lime Company—TransportationCompany-Transportation (“Transportation”) primarily to deliver some of the Company’s products to its customers and facilities primarily in the Dallas‑Ft. Worth Metroplex. In December 2014, US Lime acquired the land and buildings, and Transportation acquired the trucks, trailers and other equipment, owned by a Houston, Texas trucking company operation that had exclusively delivered the Company’s products to its customers and slurry facilities. The land purchased included the site leased for one of US Lime’s Houston slurry facility. In December 2017, Transportation sold its trucks in Houston, Texas for approximately their net book value and entered into a dedicated transportation services agreement with a third-party carrier to deliver the Company’s products to its customers and slurry facilities in the Houston metropolitan area.Texas.

U.S. Lime Company—Company - Shreveport operates a distribution terminal in Shreveport, Louisiana, which is connected to a railroad, to provide lime storage, hydrating, slurrying and distribution capacity to service markets in Louisiana and East Texas.

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

Employees.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, 2017,2022, the Company employed 318338 persons, and73 of whom were represented by unions. The Company is a party to two collective bargaining agreements. The collective bargaining agreement for the Texas facilities expires in November 2020.2023. The collective bargaining agreement for the Carthage facilities expires in May 2025. A collective bargaining agreement for the Arkansas facilities was renegotiatedset to expire in January 20182023; however, in November 2022, the Company received objective evidence that a majority of the bargaining unit employees at the Arkansas facilities no longer supported union representation, and expiresthe Company, therefore, withdrew recognition from the union. The withdrawal of recognition is pending a review in January 2023.Region 15 of the National Labor Relations Board. 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 2022 were based on each employee’s individual performance and accomplishments, as well as those of the Company, including productivity, sales, controlling costs, 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.

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 efforts 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‑qualityhigh-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‑effectivecost-effective production and distribution; clean air and anti‑pollutionanti-pollution regulations, including those related to greenhouse gas emissions, which make it more difficult to obtain permitting for new sources of emissions, such as lime kilns; and the high capital cost of the plants and facilities. These considerations reinforce the premium value of operations having permitted, long‑term, high‑qualitylong-term, high-quality limestone reservesresources and good locations and transportation relative to markets.

Lime producers tend to be concentrated on known high‑high-quality limestone formations where competition takes place principally on a regional basis. The industry as a whole has expanded its customer base, and whileWhile the steel industry and environmental‑relatedenvironmental-related users including utility plants, are the largest market sectors, itthe 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.

However, inIn recent years, the lime industry has experienced reduced demand from certain industries includingas they experience cyclical or secular downturns. For example, demand from the Company’s steel industry.  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 in some instances, choosing

continuing to use more natural gas and renewable sources for power generation instead of coal, with the permitting of new coal-fired utility plants becoming extremely difficult, 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‑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. The Company’s Texas and ArkansasWe believe that our modernization and expansion projects in Texas, Arkansas, and the recently begun construction of a new more fuel-efficient vertical kiln at its St. Clair operations in Oklahoma and our recent acquisitions, along with itsour lime slurry operations in Texas, should allow the Companyus to continue to remain competitive, protect itsour markets and position itselfourselves for the future. In addition, the Companywe will continue to evaluate internal and external opportunities for expansion, growth and increased profitability, as conditions warrant, or opportunities arise.

ImpactCompliance 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 uponon which it operates limestone quarries, antwo underground mine,mines, lime plants and other facilities with inherent environmental responsibilities, and environmental compliance costs and liabilities, including capital,liabilities. These include maintenance and operating costs with respect tofor pollution control equipment, the cost of ongoing monitoring and reporting programs, the cost of reclamation and remediation 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, and 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 compliance activities.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 apply for Title V operating permits that have significant ongoing compliance monitoring costs.  In addition to the Title V permits,Permits and other environmental operating permitsauthorizations under Environmental Laws are required for the Company’s operations, and such permits are subject to modification during the permit renewal process and, in very rare instances, could be revoked.

The Clean Air Act and analogous state laws require us to revocation.  Raw materialsobtain authorization to construct or modify existing facilities, and fuelsthe Company’s lime plants are subject to operating permits that have significant ongoing compliance costs. Over time, the EPA has increased the stringency of the National Ambient Air Quality Standards (“NAAQS”), which are used to manufacture lime products contain chemicalsestablish air emission permitting limits under the Clean Air Act. The EPA has lowered ozone standards and compounds, such as trace metals, that may be classified as hazardous substances.reclassified areas where State Implementation Plans (the “SIPs”) exist. In October 2015, the EPA issued a final rule lowering the National Ambient Air Quality Standards (“NAAQS”) for ground-level ozone from 75 parts per billionNAAQS to 70 parts per billion. The final rule requiresIn November 2022, the Dallas-Fort Worth nonattainment area, which includes the Texas Lime facility, was re-designated as “severe nonattainment.” State environmental agencies in the states in which the Company operates are currently in the process of revising their SIPs to comply with the new ground-level ozone NAAQS and the redesignation of nonattainment areas. Most recently, in January 2023, EPA announced its proposed decision to reduce the NAAQS for fine particulate matter.

These and similar rulemakings could increase the cost of future plant modifications or expansions, may make it difficult or impossible to obtain new authorizations and permits for new facilities, may require the Company to purchase emissions offsets as a condition of new authorizations and permits, and may increase compliance costs and have a material adverse effect on the Company’s financial condition, results of operations, cash flows and competitive position.

In January 2023, under Section 112 of the Clean Air Act, EPA proposed amendments to the National Emission Standards for Hazardous Air Pollutants (“NESHAPs”) for lime plants, which would revise their State Implementation Plansthe standards required to meet the maximum achievable control technology (“SIP”MACT”) within three years of the datelime industry. This proposed rule would establish stringent emission limitations for four hazardous air pollutants which will require additional pollution control equipment at our lime kilns subject to the rule. While the proposed rule is currently undergoing public comment, it is uncertain what limits the EPA designates nonattainment areas underwill ultimately impose on the new standard.  The statutory deadline forlime industry and what emission controls may be required by the EPA to make initial nonattainment designations under the new standard passed in October 2017.  In late 2017, the EPA notified states of the nonattainment areas it intends to designate, but as of February 2018, the EPA has yet to formally designate nonattainment areas.  At this point, it is unclear what specific SIP revisions will be proposed.final MACT rule. It is possible,probable, however, that the final rule will incorporate more stringent standards than existing standards, which could require additional expenditures for designing, constructing, operating and maintaining pollution control equipment necessary for compliance.

EPA could adopt new SIP revisions that would result in increased compliance costs and liabilities and make permitting of major modifications more difficult.  In 2010, the EPA adopted new NAAQS for sulfur dioxide and nitrogen dioxide.  If the Company makes major modifications of any of its lime plants, the New Source Review (discussed below) permitting process may entail modeling and, potentially, installation of additional emission controls to demonstrate compliance with those new NAAQS.

As of January 1, 2010, the EPA requiredregulations 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 or possible taxes. On May 13, 2010,limits. The EPA and delegated states also regulate greenhouse gas emissions under the EPA issued a final rule “tailoring” its New Source Review permitting and Federal Operating Permit programs to apply tofor facilities with certain thresholds of greenhouse gas emissions.  This “Tailoring Rule” was challenged in court, and on June 23, 2014, the United States Supreme Court struck down the Tailoring Rule in Utility Air Regulatory Group v. Environmental Protection Agency.  In its decision, the Court held that the EPA may not impose permitting requirements on facilities based solely on their emissions of greenhouse gasses.  But, the Court also held that the EPA may regulate greenhouse gas emissions if a facility isare otherwise subject to permitting based on thetheir 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.  On December 19, 2014, the EPA issued guidance stating that the agency would exercise its enforcement discretion to not pursue enforcement of the terms and conditions of the portion of the permitting regulations struck down by the Supreme Court in Utility Air Regulatory Group

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 current 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 rulemaking followingregulation related to the Utility Air Regulatory Group decisionParis 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 thatrates. 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 the courts,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.impacts.

The lime industry is currently undergoing a revision to an EPA rulemaking process pursuant to a federal regulation that regulates air emissions by establishing national standards that meet the maximum achievable control technology (“MACT”) available within the industry.  Also known as the “Lime MACT,” this rule is the second revision to the initial Lime MACT promulgated on January 5, 2004. It is expected that the rulemaking process may take 2-4 years before any new EPA standards would take effect.  Changes in the Lime MACT could have a material adverse effect on the Company’s financial condition, results of operations, cash flows and competitive position.

The Company also holds permits for process water and storm water discharges.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 approximately $0.4$0.8 million, $0.5 million, and $0.5$0.7 million in 2017, 20162022, 2021, and 2015,2020, 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 approximately$0.4 million, $0.7 million $0.9 million and $1.0$0.5 million in 2017, 20162022, 2021 and 2015,2020, 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 vacated. 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.

For further information, see Exhibit 95.1 to this Report on Form 10-K.

Reclamation and Remediation.The Company recognizes legal reclamation and remediation obligations associated with the retirement of long‑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 $1.6 million for AROs at December 31, 20172022 is reasonable.

Pursuant to the Drillsite Agreement, the Company receivesdrillsite agreement, U.S. Lime – O&G has a 3% royalty interest and a 12.5% non-operatingnon-operated working interest. At December 31, 2022, U.S. Lime – O&G had a combined 12.4% royalty and non-operated working interest resulting in a 12.4% revenue interest, in the six XTOon 6 active wells drilled fromon a padsite located on the Company’sJohnson County, Texas property.

U.S. Lime O & G has no direct employees and is not the operator of any wells drilled on the properties subject to either the O & G Lease or the Drillsite Agreement (the “O & G Properties”). The only decision that the Company has the right to make is whether to participate as a non‑operating working interest owner and pay its proportionate share of the costs of drilling, completing, working over and operating a well.

No wells have been completed on the O & G Properties since 2011.  Given current market prices for natural gas and natural gas liquids, there are no present plans to drill additional wells on the O & G Properties.  The Company cannot predict if any additional wells will be drilled on the O & G Properties, or their results.

Regulation.  Many aspects of the production, pricing and marketing of natural gas are regulated by federal and state agencies. Legislation and rulemaking affecting the natural gas industry are under constant review for amendment or expansion, which in the past has increased the regulatory burden on affected members of the industry. 

Oil and gas development and production operations are subject to various types of regulation at the federal, state and local levels that may impact the Company’s royalty and non‑operating working interests. Such regulation includes:

·

requiring permits for the drilling of wells;

·

numerous federal and state safety requirements;

·

environmental requirements;

·

property taxes and severance taxes; and

·

specific state and federal income tax provisions.

The TCEQ has adopted regulations limiting air emissions from oil and natural gas production in the Barnett Shale, where the O & G Properties are located. The EPA has adopted greenhouse gas monitoring and reporting regulations applicable to the petroleum and natural gas industry that require persons that hold state drilling permits that will result in annual greenhouse gas emissions of 25,000 metric tons or more to report annually those emissions from certain sources. The EPA has indicated that it will use data collected through the reporting rules to decide whether to promulgate future greenhouse gas emission limits. Future changes to greenhouse gas regulations could affect the relative competitiveness of, and therefore the demand for, natural gas and other fossil fuels.

Hydraulic fracturing is a technique used to produce oil and natural gas from shale, including the Barnett Shale Formation.  The drilling on the Company’s O & G Properties has involved hydraulic fracturing.  On April 18, 2012, the EPA issued new final regulations under the New Source Performance Standards and National Emission Standards for Hazardous Air Pollutants.    Since January 2015, these regulations have required owners and operators of newly hydraulically fractured wells to use so-called “green completion” technology to reduce methane and volatile organic compound emissions during completion activities. In May 2016, the EPA issued a final rule establishing standards for the reduction of methane, volatile organic compounds, and other emissions from new and existing sources in the oil and

8


gas sector.  These and other similar regulations could increase the costs of oil and gas exploration and production activities.   

Hydraulic fracturing has historically been regulated by state oil and natural gas commissions.  However, the EPA has asserted federal regulatory authority over certain hydraulic fracturing activities involving diesel under the Safe Drinking Water Act (“SDWA”).  In February 2014, the EPA issued permitting guidance for oil and gas hydraulic fracturing activities using diesel fuels, which included a broad definition of diesel covering a variety of oils that are not diesel but that have similar carbon-chain molecules.  In June 2016, the EPA issued a final rule establishing a zero discharge limitation for the discharge of wastewater from hydraulic fracturing to publicly owned treatment works.  In addition, certain other governmental reviews have been conducted or are underway that focus on environmental aspects of hydraulic fracturing practices, including a four-year study by the EPA that concluded in 2016.  Other agencies, including the Department of Energy, the Council on Environmental Quality, the Energy Information Administration and the Department of the Interior, have also conducted hydraulic fracturing studies. These completed and ongoing reviews, depending on their scope and results, could spur initiatives to further regulate hydraulic fracturing under the SDWA or other regulatory programs.

Additionally, the Congress, the EPA and various states have proposed or adopted legislation or regulations regulating or requiring disclosure regarding hydraulic fracturing in connection with drilling operations.  For example, pursuant to legislation adopted by the State of Texas in June 2011, the Texas Railroad Commission enacted a rule in December 2011 requiring disclosure of certain information regarding additives, chemical ingredients, concentrations and water volumes used in hydraulic fracturing.New laws or regulations affecting hydraulic fracturing could adversely affect the cost of drilling and production from the O & G Properties.

Customers and Pricing.  The pricing of natural gas sales is primarily determined by supply and demand in the marketplace and can fluctuate considerably. As the Company is not the operator of the wells drilled on the O & G Properties, it has limited access to timely information, involvement and operational control over the volumes of natural gas produced and sold and the terms and conditions, including price, on which such volumes are marketed and sold, all of which is controlled by the operators. Although the Company has the right to take its portion of natural gas production in kind, it currently has elected to have its natural gas production marketed by the operators.

The prices that the Company receives for its natural gas production is also affected by the amount of natural gas liquids included in the natural gas and the prices for those liquids. There has been a general decline in prices for natural gas and natural gas liquids in recent years due principally to increased supply, although this longer-term trend for natural gas liquids reversed somewhat in 2017.

Drilling Activity.No new wells have been completed since 2011, and there are no present plans to drill additional wells onunder either the O & G Properties. The Company cannot predict the number of additional wells that ultimately will be drilled, if any, or their results.

Production Activity.  The number of gross and net producing wells and production activity for the years ended December 31, 2017, 2016 and 2015 are as follows:

Delivery Commitments.  There are no delivery commitments for the Company’s natural gas production to which U.S. Lime O & G is a party.

Internal Controls Over Reserves Estimates.  The Company’s policies regarding internal controls over the recording of reserve estimates require reserves to be in compliance with the SEC definitions and guidance and prepared in accordance with generally accepted petroleum engineering principles. In 2017, the Company retained LaRoche Petroleum Consultants, Ltd., independent third-party petroleum engineers, to perform appraisals of 100% of its proved reserves in compliance with these standards.  In each of the years 2016 and 2015, the Company retained DeGolyer and MacNaughton, independent third‑party petroleum engineers, to perform appraisals of 100% of its proved reserves in compliance with these standards.

Reserves.  The following table reflects the proved developed, proved undeveloped and total proved reserves (all of which are located in Johnson County, Texas), future estimated net revenues and standardized measure at December 31, 2017, 2016 and 2015. The reserves and future estimated net revenues are based on the reports prepared by LaRoche Petroleum Consultants, Ltd.interests were $0.9 million as of December 31, 2017 and DeGolyer and MacNaughton as of December 31, 2016 and 2015. Proved developed reserves included 39 producing wells at each of December 31, 2017, 2016 and 2015, respectively. The Company’s proved reserves have not been filed with, or included in, any reports to any federal agency, other than those filed with the SEC.2022.

(1)

This present value data should not be construed as representative of fair market value, since such data is based upon projected cash flows, which do not provide for escalation or reduction of natural gas or natural gas liquids prices or for escalation or reduction of expenses and capital costs.

(2)

The reserve estimates as of December 31, 2017, 2016 and 2015 utilized 12‑month average pricing, as required by accounting principles generally accepted in the United States of America, of $2.81, $2.65 and $2.80 per MCF of natural gas and $20.23, $16.61 and $14.92 per BBL of natural gas liquids, respectively.

Undeveloped Acreage.  Since the Company is not the operator, it has limited information regarding undeveloped acreage and does not know how many acres the operators classify as undeveloped acreage, if any, or the number of wells that ultimately will be drilled on the O & G Properties.

Glossary of Certain Oil and Gas Terms.  The definitions set forth below shall apply to the indicated terms as used in this Report. All volumes of natural gas referred to herein are stated at the legal pressure base of the state or area where the reserves exist and at 60 degrees Fahrenheit and in most instances are rounded to the nearest major multiple.

“BBL” means a standard barrel containing 42 United States gallons.

10


BCF” means one billion cubic feet under prescribed conditions of pressure and temperature and represents a basic unit for measuring the production of natural gas.

Depletion” means (i) the volume of hydrocarbons extracted from a formation over a given period of time, (ii) the rate of hydrocarbon extraction over a given period of time expressed as a percentage of the reserves existing at the beginning of such period, or (iii) the amount of cost basis at the beginning of a period attributable to the volume of hydrocarbons extracted during such period.

Formation” means a distinct geologic interval, sometimes referred to as the strata, which has characteristics (such as permeability, porosity and hydrocarbon saturations) that distinguish it from surrounding intervals.

Future estimated net revenues” means the result of applying current prices of oil and natural gas to future estimated production from oil and natural gas proved reserves, reduced by future estimated expenditures, based on current costs to be incurred, in developing and producing the proved reserves, excluding overhead.

MCF” means one thousand cubic feet under prescribed conditions of pressure and temperature and represents a basic unit for measuring the production of natural gas.

“MMBBLS” means one million BBLS.

Operator” means the individual or company responsible for the exploration, development and production of an oil or natural gas well or lease.

Proved oil and gas reserves” are those quantities of oil and natural gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulations, prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. The project to extract the hydrocarbons must have commenced or the operator must be reasonably certain that it will commence the project within a reasonable time.

(i)

The area of the reservoir considered as proved includes: (A) The area identified by drilling and limited by fluid contacts, if any, and (B) Adjacent undrilled portions of the reservoir that can, with reasonable certainty, be judged to be continuous with it and to contain economically producible oil or gas on the basis of available geoscience and engineering data.

(ii)

In the absence of data on fluid contacts, proved quantities in a reservoir are limited by the lowest known hydrocarbons as seen in a well penetration unless geoscience, engineering, or performance data and reliable technology establishes a lower contact with reasonable certainty.

(iii)

Where direct observation from well penetrations has defined a highest known oil elevation and the potential exists for an associated gas cap, proved oil reserves may be assigned in the structurally higher portions of the reservoir only if geoscience, engineering, or performance data and reliable technology establish the higher contact with reasonable certainty.

(iv)

Reserves that can be produced economically through application of improved recovery techniques (including, but not limited to, fluid injection) are included in the proved classification when: (A) Successful testing by a pilot project in an area of the reservoir with properties no more favorable than in the reservoir as a whole, the operation of an installed program in the reservoir or an analogous reservoir, or other evidence using reliable technology establishes the reasonable certainty of the engineering analysis on which the project or program was based; and (B) The project has been approved for development by all necessary parties and entities, including governmental entities.

(v)

Existing economic conditions include prices and costs at which economic producibility from a reservoir is to be determined. The price shall be the average price during the 12‑month period prior to the ending date of the period covered by the report, determined as an unweighted arithmetic average of the

11


first‑day‑of‑the‑month price for each month within such period, unless prices are defined by contractual arrangements, excluding escalations based upon future conditions.

Royalty” means an interest in an oil and gas lease that gives the owner of the interest the right to receive a portion of the production from the leased acreage (or of the proceeds of the sale thereof), but generally does not require the owner to pay any portion of the costs of drilling or operating the wells on the leased acreage.

Severance tax” means an amount of tax, surcharge or levy recovered by governmental agencies from the gross proceeds of oil and natural gas sales. Severance tax may be determined as a percentage of proceeds or as a specific amount per volumetric unit of sales. Severance tax is usually withheld from the gross proceeds of oil and natural gas sales by the first purchaser (e.g., pipeline or refinery) of production.

Standardized measure of discounted future net cash flows” (also referred to as “standardized measure”) means the value of future estimated net revenues, calculated in accordance with SEC guidelines, to be generated from the production of proved reserves net of estimated production and future development costs, using prices and costs at the date of estimation, without future escalation, and estimated income taxes, and without giving effect to non‑property related expenses such as general and administrative expenses, debt service and depreciation, depletion and amortization, and discounted using an annual discount rate of 10%.

Undeveloped acreage” means acreage on which wells have not been drilled or completed to a point that would permit the production of commercial quantities of oil and natural gas regardless of whether such acreage contains proved reserves.

Working interest” means a real property interest entitling the owner to receive a specified percentage of the proceeds of the sale of oil and natural gas production or a percentage of the production, but requires the owner of the working interest to bear the cost to explore for, develop and produce such oil and natural gas.

ITEM 1A. RISK FACTORS.FACTORS.

General.Industry Risks

Both of our business segmentsOur Lime and Limestone Operations are affected by general economic and regulatory conditions in the U.S. and specific economic and regulatory conditions in particular industries.

General economic conditions in the United States and specific economic conditions in recent years haveparticular industries.

General and industry specific economic conditions in the United States could lead to reduced demand for our lime and limestone products. Specifically, demand from our steel and utility customers has decreased in recent years. Our steel customers have reduced their purchase volumes due to the ongoing difficult economic conditions in that industry.  Demand from our utility customers has decreased due to the continuing trend in the United States to retire coal-fired utility plants. TheOur steel and oil and gas services customers reduce their purchase volumes, at times, due to cyclical economic conditions in their industries. Any overall reduction in demand for lime and limestone products has also resultedcould result in increased competitive pressures, including pricing pressures,pressure and competition for certain customer accounts, from other lime producers.

Reduced prices for natural gas and natural gas liquids over the past several years have resulted in reduced revenues from our Natural Gas Interests.  However, we have generally benefited from lower energy costs in our Lime and Limestone Operations segment.  In 2017, prices of natural gas and natural gas liquids recovered somewhat.

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

12


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.

We may be adversely affected by any disruption in, or failure of, our information technology systems, including due to cybersecurity risks and incidents.

We rely upon the capacity, reliability and security of our information technology (“IT”) systems for our 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 may remain vulnerable to intrusion and damage despite our implementation of security measures that we feel protect our IT systems. 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 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 can increase and our reputation, business, results of operations and financial condition could be materially adversely affected.

Lime and Limestone Operations.

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 the product output from the shaft kiln technology being deployed at the St. Clair facility, including our ability to sell our increased lime capacity at acceptable prices, our ability to execute our strategies and complete projects on time and within budget, our ability to integrate, refurbish and/or improve acquired facilities, our access to capital, volatile costs, especially fuel, electricity, transportation and freight costs, inclement weather and the effects of seasonal trends.

We receive most of our coal and petroleum coke by rail, so the availability of sufficient solid fuels to run our plants could be diminished significantly in the event of major rail disruptions. Domestic coal and petroleum coke may also be exported, which can increase competition and prices for the domestic supply. In addition, our freight costs to deliver our lime and limestone products are high relative to the value of our products, and they have generally increased in recent years. Our costs for delivery of solid fuels, as well as our products, also increase as demand for rail and trucking by other industries increases, and recent Department of Transportation rules reduce the availability of rail cars and trucks 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.

13


We quote on a delivered price basis to certain customers, which requires us to estimate future delivery costs. Our actual delivery costs may exceed these estimates, which would reduce our profitability.

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

Governmental fiscal and budgetary constraints and legislative impasses 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 and legislative impasses may adversely impact our financial condition and results of operations in various ways, including possibly reduced funding for transportation programs by federal, state and local governmental agencies, which could reduce demand for our lime and limestone products from our construction customers.

Our mining and other operations are subject to operating risks that are beyond our control, which could result in materially increased operating expenses and decreased production and shipment levels that could materially adversely affect our Lime and Limestone Operations and their profitability.

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

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

We incur environmental compliance costs13

Table of Contents

The lime and liabilities, including capital, maintenancelimestone industry is highly regionalized and operating costs,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 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.  Even with the current period of regulatory uncertainty that could result in deregulation in certain areas, we expect these costs and liabilities to continue or increase, including possible new costs, taxes and limitations on operations such as those related to possible climate change initiatives, including regulation of greenhouse gas emissions.  Similar environmental costs and liabilities may also be faced by our customers.

The rate of change of Environmental Laws has been rapid over the last decade, andany key competitive factor, we may face possible new uncertainties, costs and liabilities, taxes and limitations on operations, including those relatedfind it difficult to climate change initiatives.  Even with the current period of regulatory uncertainty that could result in deregulation in certain areas, we expectincrease or maintain our expenditure requirements for future environmental compliance, including complying with the new nitrogen dioxide, sulfur dioxide and particulate matter emission limitations under the NAAQS and regulation of greenhouse gas emissions, to continue or increase.  Discovery of currently unknown conditions and unforeseen costs and liabilities could require additional expenditures. 

The regulation of greenhouse gas emissions remains an issue for the Company and some of its customers. There is no assurance that changes in the law or regulations will not be adopted, such as the imposition of a carbon tax, a cap-and-trade program requiring companies to purchase carbon credits, or other measures that would require reductions in

14


emissions or changes to raw materials, fuel use or production rates, that could have a material adverse effect on the Company’s financial condition, results of operations, cash flows and competitive position.  More stringent regulation of greenhouse gas emissions could also adversely affect the competitiveness of some of the Company’s customers, including coal-fired power plants, and indirectly the demand for our lime and limestone products.  For example, our utility customers may switch from coal to natural gas or renewable sources for power generation for environmental 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, 2017 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 or certainty that we will be able to continue or renew our operating permits,prices or to successfully secure new permits in connection with our modernizationretain certain customer accounts, 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 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, including inflationary pressures, 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 and acquisition strategies, the uncertainty of our ability to sell our increased production capacity at acceptable prices, our ability to execute our strategies and complete projects on time and within budget, our ability to integrate, refurbish and/or improve acquired facilities, our access to capital, volatile costs, especially energy 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 availability of trucks, truck drivers and rail cars to deliver solid fuels to our plants and deliver our products to our customers. Recent events, such as the ongoing conflict between Russia and Ukraine, and the sanctions and other actions resulting therefrom, could further increase our energy costs. Additionally, recent railroad delivery issues have prevented us from receiving contractual levels of coal and petroleum coke on a timely basis. If we are unable to continue to pass along our increasing costs to customers through higher prices or surcharges, or unable to timely receive contracted supplies of solid fuel to run our plants, 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 have currently undertaken our new kiln project at St. Clair. Wein the past, and may in the future, undertake additional modernization and expansion and development projects and acquisitions. Such projects and acquisitions may require that we incur additionalsubstantial debt, which may not be

14

Table of Contents

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,generally kept up with inflation, we have experienced periods of pricing competition has increasedand pressures in recent years. We are unable to predict future demand and prices, given the current economic and regulatory uncertainties in the U.S.United States 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.

TheWe may be limited in our ability to insure against certain risk of our operations.

Mining limestone and producing lime industry is highly regionalized and competitive.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 competitorsIT systems security measures are predominately large private companies. The primary competitive factorsfocused 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, ransomware, or technological failure. Any failure, accident or security breach involving our IT systems could result in disruption to our operations. A material breach in the lime industry are price, quality, ability to meet customer demandssecurity of our IT systems could negatively impact our mining and specifications, proximity tomanufacturing operations, sales or financial and administrative functions or result in the compromise of personal information of our employees, customers personal relationships and timeliness of deliveries, with varying emphasis on these factors depending upon the specific product application.or suppliers. To the extent that oneany such failure, accident or moresecurity breach results in disruption to our operations or sales or loss or disclosure of, or damage to, our competitors becomes more successfuldata or confidential information, our costs could increase, and our reputation, business, results of operations, competitive position, and financial condition could be materially adversely affected. Additionally, should we experience a cyber-security event, we may incur substantial costs, including remediation costs, such as liability for stolen assets or information, repairs of system damage, legal costs and costs associated with respect to any key competitive factor, ourregulatory actions.

COVID-19 Risks

Our financial condition, results of operations, cash flows, and competitive position could be materially adversely affected.impacted by pandemics, epidemics, or disease outbreaks, such as the COVID-19 pandemic.

Disruptions caused by pandemics, epidemics or disease outbreaks, such as COVID-19, could materially adversely impact our financial condition, results of operations, cash flows, and competitive position. The ongoing COVID-19 pandemic continues to impact our business, particularly as it relates to rising costs and supply chain delays and disruptions, which may be amplified by new variants of the COVID-19 virus and governmental responses to any outbreaks of infections. The extent to which the pandemic will continue to impact our business results and operations remains uncertain considering the rapidly evolving environment, duration and severity of the spread of COVID-19, and emerging variants.

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 mine and

Natural Gas Interests.

Our natural gas reserves are depleting assets,plant shutdowns due to contagion, in which case we may not be able to shift production to our other mines and we have noplants; cause delays and disruptions to our supply chain as it relates to our suppliers, as well as delay and disrupt the supply chains of our customers; impede our ability to explore for new reserves, nor at current market prices are there any present plans to drill additional wells on the O&G Properties.

Revenues frommaintain and repair our Natural Gas Interests depend in large part on the quantity of natural gasplants and natural gas liquids produced from the O & G Properties. Our 39 producing wells will naturally experience declines in production rates due to depletion of their natural gas reserves,equipment; negatively impact our modernization, expansion, and the operators may determine to temporarily shut in or to plug and abandon a producing well if they believe that it is no longer economical to continue production from the well. We have nodevelopment plans; negatively impact our ability to explore for new reserves,integrate acquisitions; as well as adversely impact demand and at current market prices for natural gasour lime and natural gas liquids, therelimestone products and increase our costs.  Although we cannot predict future developments, which are no present plans to drill additional wells onhighly uncertain, including the O & G Properties, thus limiting our Natural Gas Interests revenues to production from our existing wells.

Historically,scope and duration of the markets for natural gaspandemic, and natural gas liquids have been volatile and may continue to be volatile inactions taken by governmental authorities, including mandated vaccination programs, the future.

Various factors that are beyond our control will affect the demand for, and prices of, natural gas and natural gas liquids. The natural gas industry is cyclical in nature and tends to reflect general economic and gas supply and demand conditions. Recent technological advances, such as hydraulic fracturing, have enabled the industry to access additional reserves and have greatly increased the current supply of natural gas and natural gas liquids in the United States and elsewhere, generally resulting in lower natural gas and natural gas liquids prices. Lower natural gas and natural gas liquids prices may reduce the amount of natural gas and natural gas liquids that is economical for our operators to produce on the O & G Properties, or cause them to shut in wells for extended periods of time or to plug and abandon wells. Reduced prices and production could further reduce our revenues and cash flows from our Natural Gas Interests, while at the same time also increasing the rate at which we record non-cash depletion expense on our wells, and thusCOVID-19 pandemic could have ana material adverse effect on our gross profit fromfinancial condition, results of operations, cash flows and competitive position.

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 Natural Gas Interests.

We do not control production operations on the O & G Properties, which couldcost of compliance and adversely impact our Natural Gas Interests.financial condition, results of operations, cash flows and competitive position.

AsWe are in a period of regulatory uncertainty, which has been heightened by the ownercurrent divides in the branches of royaltythe United States federal government. The Administration and non‑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 fiscal and budgetary constraints, including the timing and amount of construction and infrastructure spending, changes to tax laws, legislative impasses, extended government shutdowns, fallout from a potential U.S. government default on its obligations, pandemics, trade wars, tariffs, social unrest, international incidents, and increased inflationary pressures and interest rates, could have a material adverse effect on our financial condition, results of operations, cash flows and competitive position.

We incur environmental compliance costs and liabilities in our Lime and Limestone Operations, including capital, maintenance and operating working interests,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 abilitycompliance with Environmental Laws. We expect these costs and liabilities to influence production fromcontinue 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 O & G Properties is severely limited. All decisionslast decade, and we may face possible new uncertainties, costs and liabilities, taxes and limitations on operations, including those related to production on the O & G Properties will be madeclimate change initiatives. Changes in policy or political leadership may affect how Environmental Laws are interpreted or enforced by the operatorsEPA and maystate governmental agencies. The current 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 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 us and some of our customers. In February 2021, the current 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 influenced by factors beyondadopted, 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 our control,financial condition, results of operations, cash flows and competitive position.

More stringent regulation of greenhouse gas emissions could also adversely affect the competitiveness of some of our customers, including but not limitedcoal-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 naturalregulatory as well as cost reasons, thus reducing demand for our lime and limestone products for flue gas liquids prices, pipeline capacities, interest rates, budgetary considerationstreatment processes.

We intend to comply with all Environmental Laws and general industrybelieve our accrual for environmental costs and economic conditions.

The occurrence of an operational risk or uncertainty that materially impacts the operationsliabilities at December 31, 2022, is reasonable. Because many of the operators of the O & G Properties could have an adverse effect on the amountrequirements 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 receivewill be able to successfully secure new permits in connection with our interests in production fromfuture modernization and expansion and development projects, and it is not possible to accurately predict the O & G Properties, which could have an adverseaggregate future costs and liabilities relating to environmental compliance and their effect on our gross profit from our Natural Gas Interests.financial condition, results of operations, cash flows and competitive position.

Our natural gas gross profit is affected by productionlime and other costs, some of which are outside of our control, and possible unitizations.

The Natural Gas Interests gross profit that comes from our non-operating working interests, and to a lesser extent our royalty interests, is directly affected by increases in production and other costs, including depletion expense, as well as unitizations of existing wells. Some of these costs are outside our control, including production costs, costs of regulatory compliance and severance and other similar taxes. Other expenditures are dictated by business necessity, such as working over existing wells to increase recovery rates.

Governmental policies, laws and regulations could have an adverse impact on the O & G Properties and our natural gas business.

The O & G Properties and our natural gas businesslimestone operations are subject to complex federal, state and local laws and regulationsvarious regulatory risks, including those relating to mine safety, and reclamation and remediation obligations.

Our mining operations are subject to mine safety regulation under the oilMine Act. The Mine Act has been construed as authorizing MSHA to issue citations and natural gas industry,orders pursuant to the legal doctrine of strict liability, or liability without fault. Citations and orders can be contested before the Commission, and as well as regulations relating to health and safety matters.

Over time, the ownershipliability for AROs is recorded at its present value each period through accretion expense, and production of natural gas, we expect to have some risk of exposure to environmental costs and liabilities. The costs and liabilities associated with environmental compliance or remediation could reduce the gross profits we would receive from our Natural Gas Interests.  The O & G Properties continue to be subject to extensive federal, state and local regulatory requirements relating to environmental affairs, health and safety and waste management.

Any increased regulation of natural gas production could increase our production costs oncapitalized cost is amortized over the O & G Properties and adversely affect our gross profit from our Natural Gas Interests.

Further, under certain environmental laws and regulations, the operators and ownersuseful life of the underlying properties could alsorelated asset. Upon settlement of the liability, we either settle the ARO for its recorded amount or recognize a gain or loss.

General.

We have identified twoone reportable business segmentssegment based on the distinctness of theirour activities and products: Lime and Limestone Operations and Natural Gas Interests.Operations. All operations are in the United States. In evaluating the operating resultsOperating profit from our Lime and Limestone Operations includes all of our segments, management primarily reviews revenuesselling, general and gross profit.administrative costs. We do not allocate corporate overhead or interest costsexpense and interest and other income to our business segments.

Our Lime and Limestone Operations representOperations.

On July 1, 2020, we acquired Carthage, a limestone mining and production company located in Carthage, Missouri, for $8.4 million cash. On February 9, 2022, we acquired Mill Creek, a dolomite mining and production company located in Mill Creek, Oklahoma, for $5.6 million cash. We believe that these acquisitions will complement our principal business. existing geographic footprint.

Our Natural Gas Interests consistOther operations relate to our natural gas interests, consisting of royalty and non‑operatingnon-operated working interests under the O & G Leasean oil and the Drillsite Agreementgas lease and a drillsite agreement with two separate

operators related to our Johnson County, Texas property, located in the Barnett Shale Formation, on which Texas Lime conducts its lime and limestone operations. Our principal management decisionsIn the fourth quarter 2020, we recognized an impairment charge of $1.6 million ($1.2 million, net of tax) related to our Natural Gas Interests involve whethernatural gas interests. The carrying values of the long-lived assets related to participateour natural gas interests were $0.9 million as a non‑operating working interest owner by contributing our proportional costs for drilling proposed wells or workovers of existing wells underDecember 31, 2022. Based on current production and pricing estimates, we believe that the O & G Lease and the Drillsite Agreement. While we intend to continue to participatecarrying value of these assets will be recoverable in future natural gas wells drilled and workovers of existing wells on our O & G Properties, if any, we are notperiods.

Our revenues increased 24.8% in the business of drilling for or producing natural gas and have no personnel with expertise in that field.

2022 compared to 2021. Revenues from our Lime and Limestone Operations increased 4.0%24.6% in 20172022, compared to 2016,2021, primarily due to increased sales volumes ofdemand from our lime and limestone products in 2017, which accounted for a revenue increase of approximately 3.2% for 2017 compared to 2016.  The 2017 increase in sales volumes resulted from increased demand, principally from ourconstruction, oil and gas services, and industrial customers, partially offset by reduced demand from our environmentalsteel customers. The increase in oil and gas services demand for 2017 resulted from increased drilling activity in the Permian region due to the increase in average prices for oil and natural gas. Revenues in 20172022 were also increased, in part, due tofavorably impacted by an increase in average productselling prices for our lime and limestone products of approximately 0.8%10.6%.

Our gross profit increased 18.7% in 20172022 compared to 2016.

Revenues from our Natural Gas Interests increased 6.7% in 2017 compared to 2016 due to an increase in average prices for natural gas and natural gas liquids of approximately 19.3%, partially offset by a decrease in production volumes of approximately 12.6%, resulting from the normal declines in production rates on the Company’s existing natural gas wells.

Gross profit increased 3.9% in 2017 compared to 2016.2021. Gross profit from our Lime and Limestone Operations in 20172022 increased 1.9%17.6%, compared to 2016,2021, primarily due to the increased revenues discussed above. Gross profitabove, partially offset by increased lime and limestone production costs, principally from our Natural Gas Interestshigher transportation, energy, labor, and supplies costs.

Our net income increased 1,113.3%$8.4 million, or 22.6%, in 20172022, compared to 2016, primarily due2021. Net income per fully diluted share increased to lower depletion and lease operating expenses and the increase$8.00 in revenues discussed above.

Interest expense remained flat at $0.2 million for each of 2017 and 2016.  Interest and other income, net, in 2017 increased $0.6 million, or 149.2%2022, compared to 2016, due to higher average cash and cash equivalent balances.$6.54 in 2021.

Income tax benefit was $2.2 million in 2017, compared to income tax expense of $5.9 million in 2016.  Income tax benefit in 2017 included a $7.4 million reduction of our deferred tax liabilities, net, due to the Tax Cuts and Jobs Act of 2017 (the “2017 Tax Act”), which was signed into law on December 22, 2017. The 2017 Tax Act reduced the enacted federal income tax rate for corporations from 35% to 21% beginning in 2018.  Applying the lower federal income tax rate to the Company’s deferred tax items resulted in a one-time reduction to the Company’s deferred tax liabilities, net, recorded as a tax benefit in the Consolidated Statements of Income in 2017.  The Company estimates that the 2017 Tax Act will result in a reduction of its future effective income tax rates by approximately 8 to 10 percentage points, compared to what it would have expected before the 2017 Tax Act was enacted.

Net income increased $9.4 million, or 52.9%, in 2017 compared to 2016. Cash flows from operations during 2017 enabled us to make $21.3$32.4 million of capital investments in 2022, including the acquisition of Mill Creek. It also enabled us to pay $3.0$4.5 million in dividends in 2022 and increase our cash balances to $85.0$133.3 million atas of December 31, 2017,2022, compared to $74.7$105.4 million atas of December 31, 2016.  We2021. As of December 31, 2022 and 2021, we had no debt outstanding at December 31, 2017.

In December 2015, we commenced a publicly announced share repurchase program to repurchase up to $10 million of our common stock.  Pursuant to that program, we repurchased 3,086 shares in December 2015 at a weighted-average price of $54.79 per share.  In 2016, we repurchased 50,068 shares at a weighted-average price of $53.52 per share.  In November 2017, we announced a 12-month extension of the repurchase program to repurchase up to approximately $7.2 million of our common stock remaining under the program through November 30, 2018.  No additional shares have been repurchased to date.

On January 30, 2018, we announced that our Board of Directors had declared a regular quarterly cash dividend of $0.135 (13.5 cents). outstanding.

Absent a significant acquisition opportunity arising during 2018,2023, we anticipate funding our operating and capital needs, including modernization and expansion and development projects, such as our new kiln project at St. Clair,

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 the winter ice and snow storms, cold weather, hurricanes, tornadoes and excessive rainfalls generally reduce the demand for lime and limestone products supplied to construction‑relatedconstruction-related customers that account for a significant amount of our revenues. Inclement weather also interferes with our open‑pitopen-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 lime and limestone 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, oil and gas services, and industrialsteel customers increased in 2017.  However, demand for2022.

In 2022, we experienced rising costs, especially transportation, energy, labor, and supplies costs, and supply chain delays and disruptions as the global economy came out of restrictions related to the COVID-19 pandemic. We continue to monitor and assess the impact of the COVID-19 pandemic, including the emergence of new variants of the virus, implementation of new or enhanced pandemic-related restrictions, and the possibility of additional wide-spread or localized outbreaks of infections, any of which could have an adverse effect on our limefinancial condition, results of operations, cash flows and limestone products from our environmental customers declined during 2017.  Oilcompetitive position.

In 2014 and natural gas prices rose from their 2016 lows throughout 2017, which resulted in increased drilling activities in 2017 and higher demand from our oil and gas services customers. At the same time, higher oil and gas prices impacted our Lime and Limestone Operations through higher transportation, freight and fuel costs during 2017.  The current Administration has announced that they will impose a 25% tariff on imported steel which should be beneficial to future demand for domestic steel.

On December 4, 2015, the President signed into law the Fixing America’s Surface Transportation Act (the “FAST Act”), the first multi‑year transportation authorization enacted in over ten years. The FAST Act authorizes $305 billion over fiscal years 2016 through 2020 that provides long-term funding certainty for surface transportation projects. Its enactment should allow states and local governments to move forward with critical transportation projects, like new highways, with confidence that the Highway Trust Fund will meet its obligations through 2020.  In addition, 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 beginning in Texas’ fiscal 2018 to be directed to the State Highway Fund and, beginning in Texas’ fiscal 2020, for certain state motor vehicle sales and rental tax revenuerevenues to be directed to the State Highway Fund. In its fiscal 2022, Texas transferred approximately $4.5 billion of such tax revenues to the State Highway Fund from these two amendments, with almost $23 billion transferred since 2015. In 2021, the United States Congress passed the Infrastructure Investment and Jobs Act, which is estimated to apportion approximately $26.9 billion to Texas for federal-aid highway programs, of which $5.2 billion was for Texas’ fiscal 2022 and the remainder is estimated for fiscal 2023 through fiscal 2026. With these funding improvements, along with additional infrastructure spending proposed by the current Administration,sources, we would expect to see increases instrong continued demand from our construction customers, but the timing and amount of theany increase in demand is uncertain.uncertain and subject to weather, political, and other factors.

Our modernization and expansion and development projects and acquisitions in Texas, Arkansas, Oklahoma and Arkansas, and our current modernization of U. S. Lime Company—St. ClairMissouri and our Texas slurry operations have positioned us to meet the demand for high‑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

up-to-date, fuel-efficient plant facilities, which hashave resulted in lower production costs and greater operating efficiencies, thus enhancing our competitive position. All of our rotary kilns are fuel‑efficientnow fuel-efficient preheater kilns, except for onekilns. The addition of the vertical kiln at St. Clair which will be replaced with a new, more fuel-efficient vertical kiln that should be completed in 2018.2019 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 lineon-line and refurbishing and/or improving acquired facilities, suchincluding the facilities acquired as St. Clair, which we acquired with the intentiona result of modernizingour recent acquisitions of Carthage and expanding,Mill Creek, 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, and have generallyour energy costs increased over the past several years.substantially in 2022. In addition, our freight costs, including the cost of diesel, prices, to deliver our products can be high relative to the value of our products and have generally increased in the past several years. Weproducts.

Historically, 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 are also proceeding with the construction ofput a new, more fuel-efficient vertical kiln in service at St. Clair, which should help usand we continually look for other ways to better manage our energy costs at that plant.our plants. 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 improve our revenues and control our operational and selling, general and administrative expenses. To maintain or improve our gross profit margins, we are focusing on maintaining, and increasing where possible, our lime and limestone prices to offset our increased costs, which is a challenging task with increased competition from other lime and limestone producers. In addition, we will continue to explore ways to increase, the operating efficiency of our plants and other facilities and expand our production capacity through acquisitions as conditions warrant or opportunities arise.

We continue to believe the enhanced efficiency and production capacity resulting from our modernization and expansion and development projects atin Texas, Arkansas, and Arkansas,Oklahoma, our new kiln project at St. Clair,expanded slurry operations, our acquisitions, including the recent acquisitions of Carthage and Mill Creek, 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,However, there can be no assurance that demand and prices for our lime and limestone products have not been sufficientwill enable us to fully utilize our additional production capacity.  In addition, there can be no assurancecapacity, nor 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;facilities and acquisitions; 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.

Natural Gas Interests.Other.

In 2004, we entered into the O & G Lease with EOG with respect to oil and gas rights onRevenues in 2022 included $2.7 million from our Cleburne, Texas property, located in the Barnett Shale Formation. Pursuant to the O & G 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‑operating working interest owner. Our overall average revenue interest is 34.7% in the 33 wells drilled under the O & G Lease that are currently producing.  Affiliated companies of Enervest, Ltd. purchased EOG’s interests in the O & G Lease, and an affiliate of Enervest, Ltd. is now the successor operator of the wells drilled under the O & G Lease.

In November 2006, we also entered into a Drillsite Agreement with XTO that has an oil and gas lease covering approximately 538 acres of land contiguous to our Johnson County, Texas property. Pursuant to this Agreement, we have a 3% royalty interest and an optional 12.5% non‑operating working interest, resulting in a 12.4% interest in revenues in the six XTO wells drilled and producing from a padsite located on our property.

No new wells have been completed since 2011, and there are no present plans to drill additional wells on the O&G Properties. We cannot predict the number of additional wells that ultimately will be drilled on the O & G Properties, if any, or their results.

The pricing of natural gas sales is primarily determined by supply and demandinterests, compared to $1.9 million in the marketplace and can fluctuate considerably. The prices that the Company receives for its2021. Gross profit in 2022 included $1.4 million from our natural gas production is also affected by the amount of natural gas liquids includedinterests, compared to $0.6 million in the natural gas, and the prices for those liquids is also subject to supply and demand factors. Although they recovered somewhat in 2017, prices of both natural gas and natural gas liquids have generally declined over the past several years, principally due to increased supply.  In addition, if estimates of our proved oil and

CRITICAL ACCOUNTING POLICIES.POLICIES AND ESTIMATES.

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

23

Table of Contents

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 in accordance with the terms of our purchase orders, contracts or purchase agreements, which are generally upon shipment, and when payment is considered probable. Revenues include external freight billed to customers with related costs in cost of revenues. Our returns and allowances are minimal. External freight billed to customers included in revenues was $23.5 million, $23.1 million and $20.1 million for 2017, 2016 and 2015, respectively, which approximates the amount of external freight billed to customers 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.

Accounts receivable.  We estimate the collectability of our trade receivables. A considerable amount of judgment is required in assessing the ultimate realization of these receivables and determining our allowance for doubtful accounts. Uncollected trade receivables are charged‑off when identified by management to be unrecoverable. The majority of our trade receivables are unsecured. Payment terms for our trade receivables are based on underlying purchase orders, contracts or purchase agreements. Credit losses relating to these receivables have generally been within management expectations and historical trends.

Successful‑efforts method for Natural Gas Interests.  We use the successful‑efforts method to account for development expenditures related to our Natural Gas Interests. Under this method, drilling and completion costs of development wells are capitalized and depleted using the units‑of‑production method. Costs to drill exploratory wells, if any, that do not find proved reserves are expensed.

Reserve estimates.  Proved oil and gas reserves are those quantities of oil and gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible from a given date forward, from known reservoirs, and under existing economic conditions, operating methods and government regulations, prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. The project to extract the hydrocarbons must have commenced or the operator must be reasonably certain it will commence the project within a reasonable time.

The volumes of our reserves are estimates that, by their nature, are subject to revision. The estimates are made using geological and reservoir data, as well as production performance data. These estimates will be reviewed annually and revised, either upward or downward, as warranted by additional performance data. If the estimates of proved reserves were to decline, the rate at which we record depletion expense would increase.

Environmental costs and liabilities.  We record environmental accruals in other liabilities, based on studies and estimates, when it is probable we have incurred a reasonably estimable cost or liability. The accruals are adjusted when further information warrants an adjustment. Environmental expenditures that extend the life, increase the capacity or improve the safety or efficiency of Company‑owned assets or are incurred to mitigate or prevent future possible environmental issues are capitalized. Other environmental costs are expensed when incurred.

25


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.

Derivatives.  Our foreign exchange hedgesIncome taxes. We utilize the asset and liability approach in reporting our income taxes. Deferred income tax assets and liabilities are recorded at their fair valuecomputed 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 our Consolidated Balance Sheetsenacted tax laws and any changesrates applicable to the periods in fair valuewhich 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 comprehensive income.income tax expense. We determinedalso assess individual tax positions to determine if they meet the fair valuecriteria for some or all of foreign exchange hedges utilizing the cash flows valuation technique.

Stock‑based compensation.  We expense all stock‑based paymentsbenefits of that position to employees and directors, including grants of stock options and restricted stock,be recognized in our Consolidated Statements of Incomefinancial statements and only recognize tax positions that meet the more-likely-than-not recognition threshold.

Environmental costs and liabilities. We record environmental accruals, including accrued reclamation costs, in other liabilities, based on their fair values. Compensationstudies and estimates, when it is probable we have incurred a reasonably estimable cost is recognized ratably overor liability. The accruals are adjusted when further information warrants an adjustment.

Capital Requirements. We require capital primarily for normal recurring capital and re‑equippingre-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 $12.0$20.0 million per year over the next several years in our Lime and Limestone Operations for normal recurring capital and re‑equippingre-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, 2017,2022, we had approximately $17.6$1.5 million including approximately $14.7 million for the St. Clair kiln project, in open orders or contractual commitmentsfor equipment and construction contracts for our Lime and Limestone Operations and none for our Natural Gas Interests.Operations.

During 2022, we experienced increased costs associated with our normal recurring capital and re-equipping projects at our plants and facilities, as part of the current overall inflationary environment. We expect that the increase in 2017 and 2016, respectively.these capital costs will result in increased DD&A expense in future periods. Net cash used in investing activities in 2016 also2021 included approximately $2.7$14.0 million for two significant projects at our Texas facilitythe development of the Love Hollow Quarry and its connection to overhaul the primary crushing systemBatesville plant and upgrade the burner management system on one of our kilns, and approximately $1.0$2.3 million to take advantage of cost-effective opportunities

Banking Facilities and Debt.    On May 7, 2015, we amended our Our credit agreement with Wells Fargo Bank, N.A. (the “Lender”) to, among other things, provide, as amended as of May 2, 2019 and November 21, 2019, provides for a $75 million revolving credit facility (the “New Revolving“Revolving Facility”) and reduced interest rate margins and commitment fees (the “Amendment”).   The Amendment also provides for 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 terms of the Amendment providecredit agreement also provides for a final maturity$10 million letter of credit sublimit under the NewRevolving Facility. The Revolving Facility and any incremental loanloans mature on May 7, 2020; interest2, 2024.

Interest rates on the Revolving Facility are, at our option, of LIBOR plus a margin of 1.000% (previously 1.750%) to 2.000% (previously 2.750%), or the Lender’s Prime Rate plus a margin of 0.000% to plus 1.000%; and a commitment fee range of 0.200% (previously 0.250%) to 0.350% (previously 0.400%) on the undrawn portion of the New Revolving Facility. The New Revolving Facility interest rate margins and commitment fee are determined quarterly in accordance with a pricing grid based upon the Company’sour Cash Flow Leverage Ratio, defined as the ratio of the Company’s total funded senior indebtedness to earnings before interest, taxes, depreciation, depletion, amortization and stock-based compensation expense (“EBITDA”) for the 12 months ended on the last day of the most recent calendar quarter, plus pro forma EBITDA from any businesses acquired during the period. Pursuant to a security agreement, dated August 25, 2004, the New Revolving Facility is secured by the Company’s existing and hereafter acquired tangible assets, intangible assets and real property. The maturity of the New 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 (previously 3.25 to 1).  As of October 27, 2016, we amended our credit agreement to increase the letter of credit sublimit under the New Revolving Facility from $5 million to $10 million. 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.

Prior to the Amendment, our credit agreement included a ten‑year $40 million term loan (the “Term Loan”), a ten‑year $20 million multiple draw term loan (the “Draw Term Loan”) and a $30 million revolving credit facility (the “Revolving Facility”) (collectively, the “Credit Facilities”).  The Term Loan required quarterly principal paymentsWe had no debt outstanding as of $0.8 million, with a final principal payment of $7.5 million due on December 31, 2015. The Draw Term Loan required quarterly principal payments of $0.4 million, with a final principal payment of $5.4 million due on December 31, 2015. The Revolving Facility was scheduled to mature on June 1, 2015. The maturity of the Term Loan, the Draw Term Loan and the Revolving Facility could have been accelerated if any event of default, as defined under the Credit Facilities, had occurred.

2022 or 2021. We had interest rate hedges, with the Lender as the counterparty to the hedges that fixed LIBOR through maturity at 4.695%, 4.875% and 5.500% on the outstanding balance of the Term Loan, 75% of the outstanding balance of the Draw Term Loan and 25% of the outstanding balance of the Draw Term Loan, respectively. Based on our LIBOR margin of 1.750% prior to the Amendment, our interest rates had been: 6.445% on the outstanding balance of the Term Loan; 6.625% on 75% of the outstanding balance of the Draw Term Loan; and 7.250% on 25% of the outstanding balance of the Draw Term Loan.

The hedges had been effective as defined under applicable accounting rules. Therefore, changes in fair value of the interest rate hedges were reflected in comprehensive income. We would have been exposed to credit losses in the

29


event of non‑performance by the counterparty to the hedges. We paid $0.2 million in aggregate quarterly settlement payments pursuant to the hedges in 2015. These payments were included in interest expense in our Consolidated Statements of Income.

We had $7.1$0.3 million of letters of credit issued under the New Revolving Facility as of December 31, 2017, including approximately $6.6 million related to the St. Clair kiln project, but no cash draws. Our letters of credit2022, which count as draws against the available commitment under the New Revolving Facility.

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

INTEREST RATE RISK.

We could be exposed to changes in interest rates, primarily as a result of floating interest rates on the New Revolving Facility. There was no outstanding balance on the New Revolving Facility subject to interest rate risk at December 31, 2017.2022. Any future borrowings under the New Revolving Facility would be subject to interest rate risk. See Note 3 of Notes to Consolidated Financial Statements.

FOREIGN EXCHANGE RISK.

We could be exposed to changes in the Euro to U.S. Dollar exchange rate for our approximately 3.7 million Euros obligation related to a contract for the St. Clair kiln project.  We entered into foreign exchange hedges to fix our U.S. Dollar liability at approximately $4.4 million.  See Note 9 of Notes to Consolidated Financial Statements.

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, 2022 and 2021, the related consolidated statements of income, comprehensive income, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2022, 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, 2022 and 2021, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2022, 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, 2022, 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 23, 2023 expressed an unqualified opinion.

Basis for opinion

We conducted our audits in accordance with the standards of the PCAOB.

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.

We believe that our audits provide a reasonable basis for our opinion.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

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.

(dollars in thousands, except per share amounts)

Years Ended December 31, 2017, 20162022, 2021 and 20152020

(1) Summary of Significant Accounting Policies

(a)         Organization and Presentation

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

(b)         Principles of Consolidation

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

(c)         Use of Estimates

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

(d)         Statements of Cash Flows

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

(f)         Fair Values of Financial Instruments

Fair value is defined as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.” The Company usesoperates its Lime and Limestone Operations within a three‑tier fair value hierarchy,single geographic region and derives all revenues from that segment from the sale of lime and limestone products. See Note 9 for disaggregation of revenues by the Lime and Limestone Operations segment and Other, which classifies the inputs used in measuring fair values, in determiningCompany believes best depicts how the fair valuenature, amount, timing and uncertainty of its financial assets and liabilities. These tiers include: Level 1, defined as observable inputs such as quoted prices for identical instruments in active markets; Level 2, defined as observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities and; Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. Specific inputs that had been used to value the Company’s interest rate swap liabilities included quoted three-month LIBOR rates for the remaining life of the interest rate swaps.  Specific inputs used to value the Company’s foreign exchange hedges were Euro to U.S. Dollar exchange rates for the expected future payment dates for the Company’s commitments denominated in Euros.  There were no changes in the methods and assumptions used in measuring fair value during the period.

The carrying values of cashrevenue and cash equivalents, trade receivables, other current assets, accounts payable and accrued expenses approximate fair value due to the short maturity of these instruments.  The Company’s foreign exchange hedgesflows are carried at fair value at December 31, 2017.  See Notes 1(p), 4 and 9.

(g)(f)         Concentration of Credit Risk and Trade Receivables

Financial instruments that potentially subject the Company to a concentration of credit risk consist principally of cash and cash equivalents, trade receivables and derivative financial instruments. The Company places its cash and cash equivalents with high credithigh-credit quality financial institutions and in highly rated commercial paper or United States Treasury bills and notes with maturities, at the time of purchase, of three months or less. The Company places its derivative financial instruments with financial institutions and other firms that management believes have high credit ratings. The Company’s cash and cash equivalents at commercial banking institutions normally exceed federally insured limits. For a discussion of the credit risks associated with the Company’s derivative financial instruments, see Notes 9.

The majority of the Company’s trade receivables are unsecured. Payment terms for all trade receivables are based on the underlying purchase orders, contracts or purchase agreements.agreements, and are generally fixed, short-term, and do not contain a significant financing component. The Company estimates 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 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‑offcharged-off when identified by management to be unrecoverable. Trade receivables are presented net of the related allowance for doubtful accounts,estimated credit losses, which totaled $346$550 and $334$450 at December 31,

(i)(h)         Property, Plant and Equipment

For major constructed assets, the capitalized cost includes the price paid by the Company for labor and materials plus interest and internal and external project management costs that are directly related to the constructed assets. Machinery and equipment at December 31, 20172022 and 20162021 included $14,930$6,534 and $4,284,$12,556, respectively, of construction in progress for various capital projects. No interest costs were capitalized for the years ended December 31, 20172022 and 2016.2021. At December 31, 2022 and 2021, accounts payable and accrued expenses included $1,079 and $1,369, respectively, of capitalized costs. Depreciation of property, plant and equipment is being provided for by the straight‑linestraight-line method over estimated useful lives as follows:

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

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

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

During 2020, the Company recognized an impairment charge of $1,550to record a provisionadjust the carrying value of certain long-lived assets related to its natural gas interests. Continuing low prices for impairmentnatural gas and natural gas liquids have reduced the estimates for future economically feasible production from the Company’s drilled wells, resulting in the Company’s determination that the estimated fair value of its long‑lived assets.natural gas assets was less than their carrying value in 2020. Fair value was determined as the present value of the estimated future cash flows of the natural gas interests.

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

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

(k)(i)         Asset Retirement Obligations

The Company recognizes legal obligations for reclamation and remediation associated with the retirement of long‑long-lived assets at their fair value at the time the obligations are incurred (“AROs”). Over time, the liability for AROs is recorded at its present value each period through accretion expense, and the capitalized cost is depreciated over the useful life of the related asset. Upon settlement of the liability, the Company either settles the AROs for the recorded amount or recognizes a gain or loss. The Company’s AROs of $1,556 and $1,553 as of December 31, 2022 and 2021, respectively, are included in Other liabilities and Accrued expenses on the Company’s Consolidated Balance Sheets. As of December 31, 2017 and 2016, the Company’s AROs included in other liabilities and accrued expenses were $1,582 and $1,838, respectively. As of December 31, 2017,2022, assets, net of accumulated depreciation, associated with the Company’s AROs totaled $910.$679. During 20172022 and 2016,2021, the Company spent $377$24 and $311,$58, respectively, on its AROs, and recognized accretion expense of $73, $70$97, $92 and $60$90 in 2017, 20162022, 2021 and 2015,2020, respectively, on its AROs.

The AROs were estimated based on studies and the Company’s process knowledge and estimates and are discounted using a credit adjusted risk-free interest rate. The AROs are adjusted when further information warrants an adjustment. The Company estimates annual expenditures of approximately $100 to $200 eachper year in years 20182023 through 20222027 relating to its AROs.

(m)         Stock-Based Compensation

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

(p)         Derivative Instruments and Hedging Activities

Every derivative instrument is recorded on the Company’s Consolidated Balance Sheets as either an asset or liability measured at its fair value. Changes in the derivative’s fair value are recognized currently in earnings unless specific hedge accounting criteria are met. If the derivative is designated as a cash flow hedge, changes in fair value are recognized in comprehensive income or loss until the hedged item is recognized in earnings.  The Company estimated fair value utilizing the cash flows valuation technique. The fair values of derivative contracts that expire in less than one year are recognized as current assets or liabilities. Those that expire in more than one year are recognized as long-term assets or liabilities. See Notes 1(f), 3, 4 and 9.

(q)(n)         Income Taxes

The Company utilizes the asset and liability approach in its reporting for income taxes. Deferred income tax assets and liabilities are computed for differences between the financial statement and tax bases of assets and liabilities that will result in taxable or deductible amounts in the future based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances

are established when necessary to reduce deferred tax assets to the amount more likely than not to be realized. Income tax related interest and penalties are included in income tax expense.

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

(r)(o)         Comprehensive Income

Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. Certain changes in assets and liabilities, such as mark‑to‑marketmark-to-market gains or losses of interest rate and foreign exchange hedges, and minimum pension liability adjustments, are reported as a separate component of the stockholders’ equity section of the balance sheet. Such items, along with net income, are components of comprehensive income. See Notes 1(p), 3, 4 and 6.

(2) New Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update No. 2014-09 (“ASU 2014-09”), “Revenue from Contracts with Customers,” which stipulates that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.  To achieve this core principle, an entity should apply the following steps: (1) identify the contract(s) with a customer; (2) identify the performance obligations in the contract(s); (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract(s); and (5) recognize revenue when (or as) the entity satisfies a performance obligation.  The new guidance is effective for the Company beginning January 1, 2018.  Almost all of the Company’s purchase orders, contracts or purchase agreements do not contain performance obligations other than delivery of the agreed upon product, which is primarily FOB shipping point.  Thus, the Company generally recognizes revenue upon shipment of the product.  The Company has analyzed its revenue generating activities and the contracts which might impact its revenue recognition in light of the new standards and does not expect the adoption of ASU 2014-09 will affect its operating profit or net income.  The Company has determined to adopt ASU 2014-09 using the modified retrospective approach and does not expect any effect on opening retained earnings at January 1, 2018.  The Company is finalizing its analysis of the incremental disclosure requirements associated with this new guidance and will complete its adoption and implementation in the first quarter 2018.

In February 2016, the FASB issued Accounting Standards Update No. 2016-02 (“ASU 2016-02”), “Leases,” which requires the recognition of lease assets and lease liabilities by lessees for all leases greater than one year in duration and classified as operating leases under previous guidance.  ASU 2016-02 is effective for fiscal years beginning after December 15, 2018 and interim periods within those periods, with early adoption permitted.  ASU 2016-02 must be adopted using a modified retrospective transition and requires application of the new guidance at the beginning of the earliest comparative period presented.  As of December 31, 2017 and 2016, the Company’s undiscounted minimum contractual commitments under long-term leases, which were not recorded on the Company’s Consolidated Balance Sheets, were $6,712 and $6,778, respectively, which is an estimate of the effect on total assets and total liabilities that the new accounting standard would have on those dates.  The Company is currently evaluating the effect that this standard will have on the Company’s Consolidated Financial Statements. 

In March 2016, the FASB issued Accounting Standards Update No. 2016-09 (“ASU 2016-09”), “Compensation–Stock Compensation,” which requires that excess tax benefits (which represent the excess of actual tax benefits received at the date of vesting or settlement over the vesting period or upon issuance of share-based payments) and tax deficiencies (which represents the amount by which actual tax benefits received at the date of vesting or

settlement is lower than the benefits recognized over the vesting period or upon issuance of share-based payments) be recorded in the income statement as a reduction or increase of income taxes when an award vests.  It also requires excess tax benefits to be classified as an operating activity in the statement of cash flows rather than a financing activity.  In addition, it simplifies other aspects of share-based payment transactions, including classification of awards that permit repurchase to satisfy statutory tax withholding requirements and classification of tax payments on behalf of employees on the statement of cash flows.  ASU 2016-09 is effective for fiscal years beginning after December 15, 2016 and interim periods within those periods, with early adoption permitted.  The Company applied ASU 2016-09 in the first quarter 2017.  Adoption of ASU 2016-09 did not have a material effect on the Company’s Consolidated Financial Statements.

In February 2018, the FASB issued Accounting Standards Update No. 2018-02 (“ASU 2018-02”), “Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.”  ASU 2018-02 allows a reclassification from Accumulated other comprehensive income to Retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017 (the “2017 Tax Act”). The amendments in this ASU are effective for fiscal years beginning after December 15, 2018 and for interim periods therein. Early adoption of ASU 2018-02 is permitted. The Company does not believe this standard will have a material effect on the Company’s Consolidated Financial Statements.

(3) (2) Banking Facilities and Debt

On May 7, 2015, the Company amended itsThe Company’s credit agreement with Wells Fargo Bank, N.A. (the “Lender”) to, among other things, provide, as amended as of May 2, 2019 and November 21, 2019, provides for a $75,000 revolving credit facility (the “New Revolving“Revolving Facility”) and reduced interest rate margins and commitment fees (the “Amendment”).   The Amendment also provides for an incremental four-year accordion feature to borrow up to an additional $50,000 on the same terms, subject to approval by the Lender or another lender selected by the Company. The terms of the Amendment providecredit agreement also provides for a final maturity$10,000 letter of credit sublimit under the NewRevolving Facility. The Revolving Facility and any incremental loanloans mature on May 7, 2020; interest2, 2024.

Interest rates on the Revolving Facility are, at the Company’s option, of LIBOR plus a margin of 1.000% (previously 1.750%) to 2.000% (previously 2.750%), or the Lender’s Prime Rate plus a margin of 0.000% to plus 1.000%; and a commitment fee range of 0.200% (previously 0.250%) to 0.350% (previously 0.400%) on the undrawn portion of the New Revolving Facility. The New Revolving Facility interest rate margins and commitment fee are determined quarterly in accordance with a pricing grid based upon the Company’s Cash Flow Leverage Ratio, defined as the ratio of the Company’s total funded senior indebtedness to earnings before interest, taxes, depreciation, depletion, amortization and stock-based compensation expense (“EBITDA”) for the 12 months ended on the last day of the most recent calendar quarter, plus pro forma EBITDA from any businesses acquired during the period. Pursuant to a security agreement, dated August 25, 2004, the New Revolving Facility is secured by the Company’s existing and hereafter acquired tangible assets, intangible assets and real property. The maturity of the New Revolving Facility and any incremental loans can be accelerated if any event of default, as defined under the credit agreement, occurs. The Company’s maximum Cash Flow Leverage Ratio is 3.50 to 1 (previously 3.25 to 1).  As of October 27, 2016, the Company amended its credit agreement to increase the letter of credit sublimit under the New Revolving Facility from $5,000 to $10,000. 1.

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

Prior to the Amendment, the Company’s credit agreement included a ten‑year $40,000 term loan (the “Term Loan”), a ten‑year $20,000 multiple draw term loan (the “Draw Term Loan”) and a $30,000 revolving credit facility (the “Revolving Facility”) (collectively, the “Credit Facilities”).  The Term Loan required quarterly principal payments of $833, with a final principal payment of $7,500 due on December 31, 2015. The Draw Term Loan required quarterly

principal payments of $417, with a final principal payment of $5,400 due on December 31, 2015. The Revolving Facility was scheduled to mature on June 1, 2015. The maturity of the Term Loan, the Draw Term Loan and the Revolving Facility could have been accelerated if any event of default, as defined under the Credit Facilities, had occurred.

The Company had interest rate hedges, with the Lender as the counterparty to the hedges, that fixed LIBOR through maturity at 4.695%, 4.875% and 5.500% on the outstanding balance of the Term Loan, 75% of the outstanding balance of the Draw Term Loan and 25% of the outstanding balance of the Draw Term Loan, respectively. Based on the current LIBOR margin of 1.750% prior to the Amendment, the Company’s interest rates had been: 6.445% on the outstanding balance of the Term Loan; 6.625% on 75% of the outstanding balance of the Draw Term Loan; and 7.250% on 25% of the outstanding balance of the Draw Term Loan.

The hedges had been effective as defined under applicable accounting rules. Therefore, changes in fair value of the interest rate hedges were reflected in comprehensive income. The Company would have been exposed to credit losses in the event of non‑performance by the counterparty to the hedges. The Company paid $191 in aggregate quarterly settlement payments pursuant to the hedges in 2015. These payments were included in interest expense in the Company’s Consolidated Statements of Income.  See Notes 1(p) and 4.

On May 7, 2015, the Company paid off the $15,400 balance then outstanding on the Term Loan and Draw Term Loan, as well as paid $500 to repurchase the related hedges, from cash on hand.  The cost to repurchase the hedges was included in interest expense.  The Company had no debt outstanding at December 31, 20172022 or 2016.2021. The Company had $7,083$347 of letters of credit issued at December 31, 2017,2022, which count as draws against the available commitment under the New Revolving Facility.

(4) Comprehensive Income(3) Leases

The Company has operating leases for the use of equipment, corporate office space, and some of its terminal and distribution facilities. The leases have remaining lease terms of 0 to 6 years, with a weighted-average remaining lease term of 3 years at December 31, 2022. Some operating leases include options to extend the leases for up to 5 years. The Company’s lease calculations include the impact of options to extend when it is reasonably certain the Company will exercise the option. The Company used a weighted-average discount rate of 3.0% and 1.1% for leases entered into during 2022 and 2021, respectively. The components of comprehensive incomenet operating lease costs for 2022, 2021 and 2020 were as follows (in thousands):

(6) (5) Employee Retirement Plans

During the second quarter 2015, after receipt of a favorable determination letter from the Internal Revenue Service, the Company terminated a noncontributory defined benefit plan that, prior to the termination, covered substantially all of the union employees previously employed by its wholly owned subsidiary, Corson Lime Company (the “Plan”).  In 1997, the Company sold substantially all of the assets of Corson Lime Company, and all benefits for participants in the Plan were frozen. During 1997 and 1998, the Company made contributions to the Plan that were intended to fully fund the benefits earned by the participants. The Company recorded comprehensive income of $602, net of $344 tax expense, for the year ended December 31, 2015. The Company made contributions of $233 to the Plan in 2015.  As a result of the termination, the Company made no contributions to the Plan in 2016 and 2017 and will not be required to make any further contributions to the Plan.

The following table sets forth the Pre-Settlement, Settlement and Post-Settlement funded status of the Plan as of June 30, 2015 (the termination date):

The fair value for the stock options was estimated at the date of grant using a lattice‑basedlattice-based option valuation model, with the following weighted‑averageweighted-average assumptions for the 2017, 20162022, 2021 and 20152020 grants: risk‑freerisk-free interest rates of 1.45%2.92% to 1.81%3.94% (weighted average 1.73%3.74%) in 2017, 0.92%2022, 0.86% to 1.49%1.26% (weighted average 1.37%1.19%) in 20162021 and 0.98%0.37% to 1.28%0.53% (weighted average 1.05%0.42%) in 2015;2020; a dividend yield of 0.54%0.57% to 0.67%0.73% (weighted average 0.57%0.62%) in 2017, 0.67%2022, 0.46% to 1.00%0.50% (weighted average 0.74%0.49%) in 2016 and2021, 0.56% to 0.80% to 0.91% (weighted average of 0.83%0.64%) in 2015;2020; and a volatility factor of .258.374 to .265.385 (weighted average .260).382) in 2017, .2642022, .366 to .275.373 (weighted average .266).371) in 20162021 and .272.346 to .284.356 (weighted average .275).354) in 2015,2020, based on the monthly per‑sharedaily per-share closing prices for threefive years preceding the date of issuance.

addition, the fair value of these options was estimated based on an expected life of threefive years. The fair value of restricted stock is based on the closing per‑shareper-share price of the Company’s common stock on the date of grant.

(8) (7) Share Repurchases

In December 2015, the Company commenced a publicly announced share repurchase program to repurchase up to $10,000 of its common stock.  During December 2015, the Company repurchased 3,086 shares at a weighted-average price of $54.79 per share.  Pursuant to the share repurchase program, in 2016 the Company repurchased 50,068 shares at a weighted-average price of $53.52 per share.  On November 17, 2017, the Company extended the repurchase program through November 30, 2018.  No shares were repurchased under the program in 2017.

In addition, during 2017,2022, pursuant to provisions in the 2001 Plan that allowsallow employees and directors to pay the tax withholding liability upon the lapse of restrictions on restricted stock in either cash and/or delivery of shares of the Company’s common stock, the Company repurchased 4,0145,630 shares at a weighted-average price of $76.97$136.50 per share.

(9) (8) Commitments and Contingencies

The Company leases some of the equipment used in its operations under operating leases. Generally, the leases are for periods varying from one to five years and are renewable at the option of the Company. The Company also has a lease for corporate office space. Total lease and rent expense was $2,359 $2,659 and $2,307 for 2017, 2016 and 2015, respectively. As of December 31, 2017, future minimum payments under operating leases that were either non‑cancelable or subject to significant penalty upon cancellation were $1,658 for 2018, $1,306 for 2019, $1,012 for 2020, $815 for 2021, $148 for 2022 and $0 thereafter.

The Company is party to lawsuits and claims arising in the normal course of business, none of which, in the opinion of management, is expected to have a material adverse effect on the Company’s financial condition, results of operations, cash flows or competitive position.

The Company is not contractually committed to any planned capital expenditures until actual orders are placed for equipment or services. At December 31, 2017,2022, the Company had approximately $14,703$1,521 for open equipment and construction contracts and orders related to the new kiln project at its St. Clair facilities. One of the contracts for this project requires future payments totaling 3,692 Euros.  To hedge against potential losses due to changes in the Euro to U.S. Dollar exchange rates, the Company has entered into foreign exchange (“FX”) hedges with Wells Fargo Bank, N.A. as the counterparty to the hedges to fix the exchange rate for the 3,692 Euros.  The hedges have been effective as defined under applicable accounting rules.  Therefore, changes in fair value of the FX hedges are reflected in comprehensive income.  The Company will be exposed to credit losses in the event of non-performance by the counterparty to the hedges.  Due to the strengthening of the Euro, compared to the U.S. Dollar during 2017, the fair value of the FX hedges resulted in an asset of $111 at December 31, 2017, which is included in prepaid expenses and other current assets ($83) and other assets, net ($28), compared to a liability of $352 at December 31, 2016, which is included in accrued expense ($309) and other liabilities ($43).  See Notes 1(f), 1(p) and 4.contracts.

Unaudited Oil and Natural Gas Reserve and Standardized Measure Information

The independent petroleum engineering firm of LaRoche Petroleum Consultants, Ltd. has been retained by the Company to estimate its proved natural gas reserves as of December 31, 2017.  The Company had retained the independent petroleum engineering firm of DeGolyer and MacNaughton to estimate its proved natural gas reserves as of December 31, 2016 and 2015.  No events have occurred since December 31, 2017 that would have a material effect on the estimated proved reserves.

The following information is presented with regard to the Company’s natural gas reserves, all of which are proved and located in the United States. These rules require inclusion, as a supplement to the basic financial statements, of a standardized measure of discounted future net cash flows relating to proved natural gas reserves. The standardized measure, in management’s opinion, should be examined with caution. The basis for these disclosures is the independent petroleum engineers’ reserve studies, which contain imprecise estimates of quantities and rates of production of reserves. Revision of estimates can have a significant impact on the results. Also, development and production improvement costs in one year may significantly change previous estimates of proved reserves and their valuation. Values of unproved properties and anticipated future price and cost increases or decreases are not considered. Therefore, the standardized measure is not necessarily a “best estimate” of the fair value of gas properties or of future net cash flows.

In calculating the future net cash flows for its royalty and non‑operating working interests in the table below as of December 31, 2017, 2016 and 2015, the Company utilized 12‑month average prices of $2.81, $2.65 and $2.80 per MCF of natural gas and $20.23, $16.61 and $14.92 per BBL of natural gas liquids, respectively.

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

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

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

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. Additionally, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate.

As of December 31, 2017,2022, management assessed the effectiveness of the Company’s internal control over financial reporting based on the criteria for effective internal control over financial reporting established in the 2013 “Internal Control—IntegratedControl-Integrated Framework,” issued by the Committee of Sponsoring Organizations of the Treadway Commission (the “COSO criteria”). Based on the assessment, management determined that the Company maintained effective internal control over financial reporting as of December 31, 2017,2022, based on the COSO criteria.

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

Changes in internal control over financial reporting. No change in the Company’s internal control over financial reporting occurred during the Company’s most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.
