Environmental, Health and Safety Matters and Government Regulation
The Company’s operations are subject to federal, state, local and foreign laws and regulations relating to the environment and health and safety. In particular, we are subject to certain requirements under the Clean Air Act. In addition, certain of the Company’s operations involve and have involved the use and release of substances that have been and are classified as toxic or hazardous within the meaning of these laws and regulations. Environmental operating permits are, or may be, required for certain of the Company’s operations and such permits are subject to modification, renewal and revocation. We are also subject to land reclamation requirements relating to our mining operations. In addition to environmental and health and safety laws and regulations, we are subject to a wide variety of other federal, state, local and foreign laws and regulations in the countries where we conduct business. The Company regularly monitors and reviews its operations, procedures and policies for compliance with these laws and regulations. Compliance with these laws and regulations often requires the dedication of time and effort of employees, as well as financial resources. The Company believes its operations are in substantial compliance with these laws and regulations and that there are no violations that would have a material effect on the Company. Despite these compliance efforts, some risk of environmental and other damage is inherent in the Company’s operations, as it is with other companies engaged in similar businesses, and there can be no assurance that material violations will not occur in the future. In fiscal 2024, compliance with the regulations applicable to us did not have a material effect on our capital expenditures, earnings, or competitive position, and the cost of compliance with these laws and regulations is not expected to have a material adverse effect on the Company in the future.
Sustainability is core to who we are and the foundation of how we operate our company. At MTI, we are focused on providing the safest workplace for our employees, reducing our environmental impact, preserving natural resources and making positive contributions to our local communities — all of which are ingrained in our values. For the past 16 years, MTI has published an annual Corporate Responsibility and Sustainability Report that describes our efforts in continuous improvement regarding our safety culture, environmental performance, social impact, new product development, and community engagement. Over the past several years, we’ve taken meaningful steps to advance our broad range of sustainability initiatives, including establishing 2025 environmental reduction targets in six focus areas: Scope 1 and Scope 2 CO2 emissions, airborne pollutants, water used, water discharged, and process waste landfilled, each on an absolute basis and per ton of production for each of our focus areas. By 2023, we met or exceeded our targets in ten out of twelve total environmental emission and discharge reduction targets.
Laws and regulations are subject to change. See Item 1A, Risk Factors, for information regarding the possible effects that compliance with new laws and regulations, including those relating to climate change, may have on our businesses and operating results.
Under the terms of certain agreements entered into in connection with the Company’s initial public offering in 1992, Pfizer Inc. (“Pfizer”) agreed to indemnify the Company against certain liabilities being retained by Pfizer and its subsidiaries including, but not limited to, pending lawsuits and claims, and any lawsuits or claims brought at any time in the future alleging damages or injury from the use, handling of or exposure to any product sold by Pfizer’s specialty minerals business prior to the closing of the initial public offering.

Item 1A. Risk Factors
Our business faces significant risks. Set forth below are all risks that we believe are material at this time. Our business, financial condition and results of operations could be materially adversely affected by any of these risks. These risks should be read in conjunction with the other information in this Annual Report on Form 10-K.
Industry and Market Risks
Worldwide general economic, business, and industry conditions may have an adverse effect on the Company’s results.
The Company’s business and operating results are affected by worldwide and regional economic, business, and industry conditions. In recent years, we have experienced, among other things, declining consumer and business confidence, volatile raw material prices, instability in credit markets, high unemployment, fluctuating interest and exchange rates, and other challenges in the countries in which we operate. Uncertainty or a deterioration in the economic conditions affecting the businesses to which, or geographic areas in which, we sell products could reduce demand for our products and inflationary pressures may increase our costs. The Company’s customers and potential customers may experience deterioration of their businesses, cash flow shortages, and difficulty obtaining financing. As discussed below, the industries we serve have in the past been adversely affected by the uncertain global economic climate due to the cyclical nature of their businesses. As a result, existing or potential customers may reduce or delay their growth and investments and their plans to purchase products, pursue inventory reduction measures, and may not be able to fulfill their obligations in a timely fashion. Further, suppliers could experience similar conditions, which could affect their ability to fulfill their obligations to the Company. We may also experience pricing pressure on products and services, or be unsuccessful in passing along to our customers an increase in our raw materials costs or energy prices, which could decrease our revenues and have an adverse effect on our financial condition and cash flows. Adversity within capital markets may also impact the Company’s results of operations by negatively affecting the amount of expense the Company records for its pension and other postretirement benefit plans. Actuarial valuations used to calculate income or expense for the plans reflect assumptions about financial market and other economic conditions – the most significant of which are the discount rate and the expected long-term rate of return on plan assets. Such actuarial valuations may change based on changes in key economic indicators. Global economic markets remain uncertain, and there can be no assurance that market conditions will improve in the near future. Future weakness in the global economy could materially and adversely affect our business and operating results.
A number of our customers’ businesses are cyclical or have changing regional demands. Our operations are subject to these trends, and we may not be able to mitigate these risks.
A significant portion of the sales of the High-Temperature product line of our Engineered Solutions segment are derived from the metalcasting market. The metalcasting market is dependent upon the demand for castings for automobile components, farm and construction equipment, oil and gas production equipment, power generation turbine castings, and rail car components. Many of these types of equipment are sensitive to fluctuations in demand during periods of recession or difficult economic conditions. This product line also serves the steel industry. In recent years, global steel production has been volatile. These trends have affected and may continue to affect the demand for our Engineered Solutions segment’s products and services. We expect steel consumption to be similar to 2024 levels.
In the paper industry, which is served by the Specialty Additives product line of our Consumer & Specialties segment, production levels for uncoated freesheet within North America and Europe, our two largest markets, are projected to continue to decrease. The reduced demand for premium writing paper products has resulted in closures and conversions of mills in both North America and Europe. We expect paper consumption to remain similar to prior year levels in both regions.
The Environmental & Infrastructure product line of our Engineered Solutions segment serves the commercial construction, infrastructure and oil & gas markets. In addition, the Specialty Additives product line of our Consumer & Specialties segment is affected by the domestic residential building and construction markets, as well as the automotive market.
Demand for our products is subject to trends in these markets. During periods of economic slowdown, our customers often reduce their capital expenditure and defer or cancel pending projects. Such developments occur even amongst customers that are not experiencing financial difficulties. In addition, these trends could cause our customers to face liquidity issues or bankruptcy, which could deteriorate the aging of our accounts receivable, increase our bad debt exposure and possibly trigger impairment of assets or realignment of our businesses. The Company has taken steps to reduce its exposure to variations in its customers’ businesses, including by diversifying its portfolio of products and services through geographic expansion, growth in less cyclical consumer-oriented markets, and by structuring most of its long-term satellite contracts to provide a degree of protection against declines in the quantity of product purchased, since the price per ton of our products generally rises as the number of tons purchased declines. In addition, many of our product lines lower our customers’ costs of production or increase their productivity, which should encourage them to use our products. However, there can be no assurance that these efforts will mitigate the risks of our dependence on these industries. Continued weakness in the industries we serve has had, and may in the future have, an adverse effect on sales of our products and our results of operations. A continued or renewed economic downturn in one or more of the industries or geographic regions that the Company serves, or in the worldwide economy, could cause actual results of operations to differ materially from historical and expected results.
13

The Company operates in very competitive industries, which could adversely affect our profitability.
The Company has many competitors. Some of our principal competitors have greater financial and other resources than we have. Accordingly, these competitors may be better able to withstand economic downturns and changes in conditions within the industries in which we operate and may have significantly greater operating and financial flexibility than we do. We also face competition for some of our products from alternative products, and some of the competition we face comes from competitors in lower-cost production countries like China and India. As a result of the competitive environment in the markets in which we operate, we currently face and will continue to face pressure on the sales prices of our products from competitors, which could reduce profit margins.
The Company’s sales could be adversely affected by consolidation in customer industries.
Several consolidations in the paper industry have taken place in recent years and such consolidation could continue in the future. These consolidations could result in partial or total closure of some paper mills where the Company operates satellite plants. Such closures would reduce the Company’s sales, except to the extent that they resulted in shifting paper production and associated purchases of calcium carbonate to another location served by the Company. Similarly, consolidations have occurred in the foundry and steel industries. Such consolidations in the major industries we serve concentrate purchasing power in the hands of a smaller number of manufacturers, enabling them to increase pressure on suppliers, such as the Company. This increased pressure could have an adverse effect on the Company’s results of operations in the future.
The Company’s sales could be adversely affected by our failure to renew or extend long-term sales contracts for our satellite operations.
The Company’s sales of calcium carbonate to paper customers are typically pursuant to long-term evergreen agreements, initially ten years in length, with paper mills where the Company operates satellite plants. Sales pursuant to these contracts represent a significant portion of our sales in the Specialty Additives product line of the Consumer & Specialties segment. The terms of many of these agreements have been extended or renewed in the past, often in connection with an expansion of the satellite plant. However, failure of a number of the Company’s customers to renew or extend existing agreements on terms as favorable to the Company as those currently in effect, or at all, could have a substantial adverse effect on the Company’s results of operations, and could also result in impairment of the assets associated with the satellite plant.
Financial Risks
Servicing the Company’s debt will require a significant amount of cash. This could reduce the Company’s flexibility to respond to changing business and economic conditions or fund capital expenditures or working capital needs. Our ability to generate cash depends on many factors beyond our control.
At December 31, 2024, the Company had $971.3 million aggregate principal amount of total indebtedness (consisting primarily of $575.0 million aggregate principal amount of loans under our term facility, $400.0 million aggregate principal amount of notes and $4.5 million outstanding under our revolving credit facility) and an additional $386.4 million of borrowing capacity under the revolving credit facility (after giving effect to $9.1 million of outstanding letters of credit). Our outstanding indebtedness will require a significant amount of cash to make interest payments. Further, the interest rate on a significant portion of our borrowings under our senior secured credit facility is based on SOFR interest rates, which has resulted in and could continue to result in higher interest expense in the event of continued increases in interest rates. Our ability to pay interest on our debt and to satisfy our other debt obligations will depend in part upon our future financial and operating performance and upon our ability to renew or refinance borrowings. Prevailing economic conditions and financial, business, competitive, regulatory and other factors, many of which are beyond our control, will affect our ability to make these payments. We cannot guarantee that our business will generate sufficient cash flow from operations or that future borrowings will be available to us in an amount sufficient to enable us to fund our liquidity needs. If we are unable to generate sufficient cash flow to meet our debt service obligations, we will have to pursue one or more alternatives, such as reducing or delaying capital or other expenditures, refinancing debt, selling assets, or raising equity capital. Further, the requirement to make significant interest payments may reduce the Company’s flexibility to respond to changing business and economic conditions or fund capital expenditure or working capital needs and may increase the Company’s vulnerability to adverse economic conditions.
14

The agreements and instruments governing our debt contain various covenants that could significantly impact our ability to operate our business.
The agreement governing our senior secured credit facility and the indenture that governs our 5.0% Senior Notes due 2028 contain a number of significant covenants that, among other things, limit our ability to: incur or guarantee additional indebtedness, pay dividends or make other distributions or repurchase or redeem capital stock, prepay, redeem or repurchase certain debt, issue certain preferred stock or similar equity securities, make loans and investments, sell or otherwise dispose of assets, incur liens, enter into transactions with affiliates, enter into agreements restricting our subsidiaries’ ability to pay dividends and consolidate, merge or sell all or substantially all of our assets. In addition, we are required to comply with specific financial ratios, including a maximum net leverage ratio, under which we are required to achieve specific financial results. Our ability to comply with these provisions may be affected by events beyond our control. A breach of any of these covenants would result in a default under the applicable agreements. In the event of any default under our senior secured credit facility, our lenders could elect to declare all amounts borrowed under the credit agreement, together with accrued interest thereon, to be due and payable. In such an event, we cannot assure you that we would have sufficient assets to pay debt then outstanding under the credit agreement, the indenture governing our notes, and any other agreements governing our debt. Any future refinancing of the senior secured credit facility is likely to contain similar restrictive covenants. We may also incur future debt obligations that might subject us to additional restrictive covenants that could affect our financial and operational flexibility. We cannot assure you that we will be granted waivers or amendments to these agreements if for any reason we are unable to comply with these agreements or that we will be able to refinance our debt on terms acceptable to us, or at all.
Technology, Development and Growth Risks
The Company’s results could be adversely affected if it is unable to effectively achieve and implement its growth initiatives.
Sales and income growth of the Company depends upon a number of uncertain events. Growth will depend in part on sales growth from our existing businesses and customers. The Company has a strategic growth initiative to increase penetration into geographic markets such as Brazil, India and China as well as other Asian and Eastern European countries. The Company also has a strategic growth initiative to increase penetration into consumer-oriented markets such as pet litter, personal care, and oil purification. Our strategy also anticipates growth through future acquisitions. However, our ability to identify and consummate any future acquisitions on terms that are favorable to us may be limited by the number of attractive acquisition targets, internal demands on our resources and our ability to obtain financing. Our success in integrating newly acquired businesses will depend upon our ability to retain key personnel, avoid diversion of management’s attention from operational matters, and integrate general and administrative services. In addition, future acquisitions could result in the incurrence of additional debt, costs and contingent liabilities. Integration of acquired operations may take longer, or be more costly or disruptive to our business, than originally anticipated, and it is also possible that expected synergies from future acquisitions may not materialize. We also may incur costs and divert management attention with regard to potential acquisitions that are never consummated. Difficulties, delays or failure of any of these strategies could affect the future growth rate of the Company.
Delays or failures in new product development could adversely affect the Company’s operations.
The Company’s future business success will depend in part upon its ability to maintain and enhance its technological capabilities, to respond to changing customer needs, and to successfully anticipate or respond to technological changes on a cost-effective and timely basis. The Company is engaged in a continuous effort to develop new products and processes in all of its product lines. Difficulties, delays or failures in the development, testing, production, marketing or sale of such new products could cause actual results of operations to differ materially from our expected results.
The Company’s ability to compete is dependent upon its ability to defend its intellectual property against inappropriate disclosure, theft and infringement.
The Company’s ability to compete is based in part upon proprietary knowledge, both patented and unpatented. The Company’s ability to achieve anticipated results depends in part on its ability to defend its intellectual property against inappropriate disclosure and theft as well as against infringement. In addition, development by the Company’s competitors of new products or technologies that are more effective or less expensive than those the Company offers could have a material adverse effect on the Company’s financial condition or results of operations.
15

The Company’s operations could be impacted by the increased risks of doing business abroad.
The Company does business in many areas internationally. Approximately 49% of our sales in 2024 were derived from outside the United States and we have significant production facilities which are located outside of the United States. We have in recent years expanded our operations in emerging markets, and we plan to continue to do so in the future, particularly in China, India, Brazil, the Middle East, and Eastern Europe. Some of our operations are located in areas that have experienced political or economic instability, including Indonesia, Malaysia, Nigeria, Egypt, Saudi Arabia, Turkey, Brazil, Thailand, China and South Africa. As the Company expands its operations overseas, it faces increased risks of doing business abroad, including inflation, fluctuation in interest rates, changes in applicable laws and regulatory requirements, nationalization, expropriation, limits on repatriation of funds, civil unrest, unstable governments and legal systems, and other factors. The U.S. and foreign countries may also adopt or increase restrictions on foreign trade or investment, including currency exchange controls, tariffs or other taxes, or limitations on imports or exports (including recent and proposed changes in U.S. trade policy and resulting retaliatory actions by other countries). Further, geopolitical and terrorism threats, including armed conflict among countries, could in the future affect our business overseas, including leading to, among other things, impairment of our or our customers’ ability to conduct operations, adverse impact to our employees, and a loss of our investment. While recent geopolitical conflicts, such as between Russia and Ukraine and between Israel and Hamas, have not significantly affected our business, the broader consequences of geopolitical and terrorism threats, which may include sanctions that prohibit our ability to do business in specific countries, embargoes, supply chain disruptions, potential contractual breaches and litigation, regional instability and geopolitical shifts, cannot be predicted. We are also subject to increased risks of natural disasters, public health crises, including the occurrence of a contagious disease or illness, such as COVID-19, and other catastrophic events in such countries. Many of these risks are beyond our control and can lead to sudden, and potentially prolonged, changes in demand for our products, difficulty in enforcing agreements, and losses in the realizability of our assets. Adverse developments in any of the areas in which we do business could cause actual results to differ materially from historical and expected results. In addition, a significant portion of our raw material purchases and sales outside the United States are denominated in foreign currencies, and liabilities for non-U.S. operating expenses and income taxes are denominated in local currencies. Accordingly, reported sales, net earnings, cash flows and fair values have been and, in the future, will be affected by changes in foreign currency exchange rates. Our overall success as a global business depends, in part, upon our ability to succeed in differing legal, regulatory, economic, social and political conditions. We cannot assure you that we will implement policies and strategies that will be effective in each location where we do business.
The Company’s operations are dependent on the availability of raw materials and access to ore reserves at its mining operations. Increases in costs of raw materials, energy, or shipping could adversely affect our financial results.
The Company depends in part on having an adequate supply of raw materials for its manufacturing operations, particularly lime and carbon dioxide for the production of PCC, and magnesia and alumina for its refractory operations. Purchase prices and availability of these critical raw materials are subject to volatility. At any given time, we may be unable to obtain an adequate supply of these critical raw materials on a timely basis, on price and other terms, or at all. While most such raw materials are readily available, the Company has purchased approximately 55% of its magnesia requirements from sources in China over the past five years. The price and availability of magnesia have fluctuated in the past and they may fluctuate in the future. Price increases for certain other of our raw materials, including petrochemical products, as well as increases in energy prices, have also affected our business. Our production processes consume a significant amount of energy, primarily electricity, diesel fuel, natural gas and coal. We use diesel fuel to operate our mining and processing equipment and our freight costs are heavily dependent upon fuel prices and surcharges. Energy costs also affect the cost of raw materials. On a combined basis, these factors represent a large exposure to petrochemical and energy products which may be subject to significant price fluctuations. The contracts pursuant to which we construct and operate our satellite plants generally adjust pricing to reflect the pass-through of increases in costs resulting from inflation, including energy. However, there is a time lag before such price adjustments can be implemented. The Company and its customers will typically negotiate reasonable price adjustments in order to recover these escalating costs, but there can be no assurance that we will be able to recover increasing costs through such negotiations.
The Company also depends on having adequate access to ore reserves of appropriate quality at its mining operations. There are numerous uncertainties inherent in estimating ore reserves including subjective judgments and determinations that are based on available geological, technical, contract and economic information. In addition, mining permits, leases and other rights are, or may be, required for certain of the Company’s mining operations. Such permits, leases and other rights are subject to modification, renewal and revocation. Our ability to maintain such mining permits, leases and other rights has been, and may continue to be, affected by changes in laws, regulations and governmental actions, particularly in emerging markets such as Turkey and China. We cannot assure you that we will be able to maintain such mining permits, leases and other rights to the extent we currently maintain them or at all.
16

The Company relies on shipping bulk cargos of bentonite from the United States, Turkey and China to customers, as well as our own subsidiaries, and we are sensitive to our ability to recover these shipping costs. If we cannot secure our container requirements or offset additional shipping costs with price increases to customers, our profitability could be impacted. We are also subject to other shipping risks. In particular, rail service interruptions have affected our ability to ship, and the availability of rail service, and our ability to recover increased rail costs, may be beyond our control. In addition, governmental restrictions can, and during the COVID-19 pandemic did, affect our ability to ship our products.
Operational Risks
The Company’s subsidiaries, BMI Oldco Inc. (f/k/a Barretts Minerals Inc.) (“Oldco”) and Barretts Ventures Texas LLC (together with Oldco, the “Chapter 11 Debtors”), have filed voluntary petitions for relief under Chapter 11 of the U.S. Bankruptcy Code to address and comprehensively resolve Oldco’s liabilities associated with talc. Risks and uncertainties related to this filing could have a material adverse effect on the Company’s business, financial condition, results of operations and cash flows.
The Company and certain of the Company’s subsidiaries are among numerous defendants in over six hundred cases seeking damages for alleged exposure to asbestos-contaminated talc products sold by the Company’s subsidiary Oldco. On October 2, 2023 (the “Petition Date”), notwithstanding the Company’s confidence in the safety of Oldco’s talc products, the Chapter 11 Debtors filed voluntary petitions for relief under Chapter 11 of the U.S. Bankruptcy Code in the United States Bankruptcy Court for the Southern District of Texas (the “Chapter 11 Cases”) to address and comprehensively resolve Oldco’s liabilities associated with talc. Minerals Technologies Inc. and the Company’s other subsidiaries were not included in the Chapter 11 filing. In the second quarter of 2024, Oldco sold its talc assets under section 363 of the U.S. Bankruptcy Code. In addition, in the second quarter of 2024, the Company entered into a Debtor-in-Possession Credit Agreement with Oldco (the "DIP Credit Agreement") and recorded a provision for credit loss of $30 million for the maximum aggregate principal amount under such DIP Credit Agreement. Proceeds of the sale of Oldco's talc assets and funds drawn by Oldco under the DIP Credit Agreement will be used to fund the Chapter 11 Cases. The Chapter 11 Debtors' ultimate goal in the Chapter 11 Cases is to confirm a plan of reorganization under Section 524(g) of the U.S. Bankruptcy Code and utilize this provision of the Bankruptcy Code to establish a trust that will address all current and future talc-related claims. In January 2024, the Chapter 11 Debtors and Minerals Technologies Inc. commenced a court-approved mediation process with the Official Committee of Unsecured Creditors (appointed in the Chapter 11 Cases as the representative of current talc claimants) (the “Committee”) and the Future Claimants Representative (appointed in the Chapter 11 Cases as the representative of future talc claimants) regarding the terms of a potential consensual plan of reorganization and the ultimate amount to be contributed to any trust. The mediation process is ongoing. During the pendency of the Chapter 11 Cases, the Company anticipates that the Chapter 11 Debtors will benefit from the operation of the automatic stay, which stays ongoing litigation in connection with talc-related claims against the Chapter 11 Debtors. In addition, subject to certain exceptions, the filing or continued prosecution of all talc-related claims against the Chapter 11 Debtors' non-debtor affiliates is temporarily stayed through April 15, 2025 (subject to further extensions), the date on which a hearing is scheduled on the status of the Chapter 11 Cases. The Chapter 11 Debtors have been deconsolidated from the Company’s financial statements since the Petition Date.
Although the Chapter 11 Cases are progressing, it is not possible at this time to predict how the Bankruptcy Court will rule on the Committee’s motion to dismiss the Chapter 11 Cases, the form of any ultimate resolution or when an ultimate resolution might occur. Accordingly, the amount that will be necessary to fully and finally resolve all of Oldco’s current and future talc-related claims in connection with a confirmed Chapter 11 plan of reorganization cannot be estimated at this time. Several risks and uncertainties related to the Chapter 11 Cases could have a material adverse effect on the Company’s business, financial condition, results of operations and cash flows, including the ultimate amount necessary to be contributed to any trust established pursuant to Section 524(g) of the U.S. Bankruptcy Code, the potential for the Company’s talc-related exposure to extend beyond the Chapter 11 Debtors arising from claims by talc plaintiffs relating to the Company’s liability for talc claims, corporate veil piercing efforts or otherwise, any final resolution of the scope of the Pfizer indemnity, the ongoing costs of the Chapter 11 Cases, which may require additional funding from time to time, the cost and the length of time necessary to ultimately resolve the cases, either through settlement or as a result of litigation arising in connection with the Chapter 11 Cases, and the possibility that the Chapter 11 Debtors will be unsuccessful in attaining relief under Chapter 11. Further, while the Company anticipates that the Chapter 11 Debtors will benefit from the operation of the automatic stay during the Chapter 11 proceedings, depending on the ultimate outcome of any of these litigation matters, the Company could in the future be required to pay significant amounts as a result of settlements or judgments, potentially in excess of liabilities accrued to date in respect of such matters. The resolution of, or recognition of additional liabilities in connection with, pending or future litigation could have a material adverse effect on the Company’s results of operations, cash flows and financial condition.
For a further discussion of the Chapter 11 Cases and Oldco's talc-related liabilities, see Note 17 to the Consolidated Financial Statements, included in this report.

The Company is subject to stringent regulation in the areas of environmental, health and safety, and tax, and may incur unanticipated costs or liabilities arising out of claims for various legal, environmental and tax matters or product stewardship issues that could materially harm the Company’s results of operations, cash flows and financial condition.
The Company’s operations are subject to international, federal, state and local governmental environmental, health and safety, tax and other laws and regulations. We have expended, and may be required to expend in the future, substantial funds for compliance with such laws and regulations. In addition, future events, such as changes to or modifications of interpretations of existing laws and regulations, or enforcement polices, or further investigation or evaluation of the potential environmental impacts of operations or health hazards of certain products, may affect our mining rights or give rise to additional compliance and other costs that could have a material adverse effect on the Company. Further, certain of our customers are subject to various federal and international laws and regulations relating to environmental and health and safety matters, especially customers of our Environmental & Infrastructure product line of our Engineered Solutions segment, who are subject to drilling permits, waste water disposal and other regulations. To the extent that these laws and regulations affecting our customers change, demand for our products and services could also change and thereby affect our financial results. State, national, and international governments and agencies have been evaluating climate-related legislation and regulation that would restrict emissions of greenhouse gases in areas in which we conduct business, and some such legislation and regulation have already been enacted or adopted. Enactment of climate-related legislation or adoption of regulation that restrict emissions of greenhouse gases in areas in which we conduct business could have an adverse effect on our operations or demand for our products. Our manufacturing processes for our products use a significant amount of energy and, should energy prices increase as a result of such legislation or regulation, we may not be able to pass these increased costs on to purchasers of our products. We cannot predict if or when currently proposed or additional laws and regulations regarding climate change or other environmental or health and safety concerns will be enacted or adopted.
The Company is also subject to income tax laws and regulations in the United States and various foreign jurisdictions. Significant judgment is required in evaluating and estimating our provision and accruals for these taxes. Our income tax liabilities are dependent upon the location of earnings among these different jurisdictions. Our income tax provision and income tax liabilities could be adversely affected by the jurisdictional mix of earnings, changes in valuation of deferred tax assets and liabilities and changes in tax treaties, laws and regulations.
The Company is currently a party in various litigation matters and tax and environmental proceedings and faces risks arising from various unasserted litigation matters, including product liability, patent infringement, antitrust claims, and claims for third-party property damage or personal injury stemming from alleged torts, including, as discussed elsewhere in this Report, a number of cases seeking damages for alleged exposure to asbestos-contaminated talc products sold by BMI Oldco. Any failure to appropriately manage safety, human health, product liability and environmental risks associated with the Company’s products and production processes could adversely impact the Company’s employees and other stakeholders, the Company’s reputation, and its results of operations, cash flows and financial condition. Public perception of the risks associated with the Company’s products and production processes could impact product acceptance and influence the regulatory environment in which the Company operates. Any unanticipated liability arising out of a current matter or proceeding, or from the other risks described above, could have a material adverse effect on the Company’s results of operations, cash flows and financial condition.
Production facilities are subject to operating risks and capacity limitations that may adversely affect the Company’s financial condition or results of operations.
The Company is dependent on the continued operation of its production facilities. Production facilities are subject to hazards associated with the manufacturing, handling, storage, and transportation of chemical materials and products, including pipeline leaks and ruptures, explosions, fires, inclement weather and natural disasters, mechanical failure, unscheduled downtime, labor difficulties, transportation interruptions, and environmental risks. Production facilities are also subject to governmental requirements that may, and during the Covid-19 pandemic did, affect our ability to operate. We maintain property, business interruption and casualty insurance but such insurance may not cover all risks associated with the hazards of our business and is subject to limitations, including deductibles and maximum liabilities covered. We may incur losses beyond the limits, or outside the coverage, of our insurance policies. Further, from time to time, we may experience capacity limitations in our manufacturing operations. In addition, if we are unable to effectively forecast our customers’ demand, it could affect our ability to successfully manage operating capacity limitations. These hazards, limitations, disruptions in supply and capacity constraints could adversely affect financial results.
18

Operating results for some of our businesses are seasonal.
Certain of our businesses are affected by seasonal weather patterns. A majority of revenues from our energy services business within the Environmental & Infrastructure product line of our Engineered Solutions segment is derived from the Gulf of Mexico and surrounding states, which are susceptible to hurricanes that typically occur June 1st through November 30th. Actual or threatened hurricanes can result in volatile demand for services provided by our energy services business. Our other businesses within the Environmental & Infrastructure product line are affected by weather patterns which determine the feasibility of construction activities. Typically, less construction activity occurs in winter months and thus this segment’s revenues tend to be greatest in the second and third quarters when weather patterns in our geographic markets are more conducive to construction activities. Additionally, some of the businesses within the Specialty Additives product line of our Consumer & Specialties segment are subject to similar seasonal patterns.
Our operations have been and will continue to be subject to cyber-attacks and other disruptions to our information systems that could have a material adverse impact on our business, consolidated results of operations, and consolidated financial condition.
Our operations are dependent on digital technologies and services. We use these technologies for activities important to our business, including managing and operating our manufacturing facilities, communications within our company and with customers and suppliers, maintaining accurate financial records, protecting confidential information, complying with regulatory, financial reporting, and legal requirements, and otherwise storing, processing and transmitting our data. Increased use of remote working arrangements has only increased our reliance on these technologies and services. Our business has in the past and could in the future be negatively affected by security incidents and systems disruptions. These disruptions or incidents may be caused by cyberattacks and other cyber incidents, network or power outages, software, equipment or telecommunications failures, the unintentional or malicious actions of employees or contractors, natural disasters, fires or other catastrophic events.
Cyberattacks and other cyber incidents are occurring more frequently, the techniques used to gain access to information technology systems and data, disable or degrade service or sabotage systems are constantly evolving and becoming more sophisticated in nature and are being carried out by groups and individuals with a wide range of expertise and motives. Cyberattacks and cyber incidents may be difficult to detect for periods of time and take many forms including cyber extortion, denial of service, social engineering, introduction of viruses or malware (such as ransomware), exploiting vulnerabilities in hardware, software or other infrastructure, hacking, website defacement or theft of passwords and other credentials, unauthorized use of computing resources and business email compromise. Continued geopolitical instability has heightened the risk of cyberattacks.
Like other global companies, our systems are subject to recurring attempts by third parties to access information, manipulate data or disrupt our operations, and we have experienced cyber incidents. If we do not allocate and effectively manage the resources necessary to continue building and maintaining our information technology infrastructure, or if we fail to timely identify or appropriately respond to cyberattacks or other cyber incidents, our business has been and can continue to be adversely affected by, among other things: interruption of our business operations; loss of or damage to intellectual property, proprietary or confidential information, or customer, supplier, or employee data; and increased costs required to prevent, respond to, or mitigate cybersecurity attacks. Similar risks exist with respect to our business partners and third-party providers that we rely upon. We are subject to the risk that the activities associated with our business partners and third-party providers can adversely affect our business even if the attack or breach does not directly impact our systems or information.
Although the cyber incidents that we have experienced to date have not had a material effect on our business, such incidents or disruptions could have a material adverse effect on us in the future. While we believe we devote significant resources to network security, disaster recovery, employee training and other measures to secure our information technology systems and prevent unauthorized access to or loss of data, there can be no guarantee that they will be adequate to safeguard against all cyber incidents, systems disruptions, or misuses of data. In addition, while we currently maintain insurance coverage that is intended to address costs associated with certain aspects of cyber incidents and information systems failures, this insurance coverage may not cover all losses or all types of claims that arise from an incident, or the damage to our reputation or brands that may result from an incident.

Item 1C. Cybersecurity
Risk Management and Strategy
The Company has processes, policies and procedures for identifying, assessing, managing, and responding to cybersecurity threats and incidents. These are integrated into our overall risk management systems, as overseen by our Board of Directors, primarily through the Audit Committee. Our policies and procedures include protocols for assessing potential material impact from cybersecurity threats and incidents, escalating to executive leadership and the Board of Directors, engaging external stakeholders, and reporting incidents based on applicable legal requirements. Our incident response plan provides guidance in the event of a cybersecurity incident, including processes with assigned roles and responsibilities to triage, contain, assess severity, escalate, investigate, and remediate incidents, as well as to comply with potentially applicable legal obligations and mitigate reputational damage.
We use cybersecurity technologies, products, specialized IT tools and services including cyber threat intelligence and external cyber technology experts to understand, manage, mitigate and continually remediate identified risks. A cybersecurity incident may be detected in a number of ways, including through the following avenues: Security Operations Center (SOC) events, employee reports such as helpdesk incidents, and cybersecurity tool and service stacks (e.g., vulnerability detection, threat intelligence, anti-virus, and malware detection tools). All cybersecurity risks are logged into the Company’s cybersecurity risk register where they are tracked for remediation. These cybersecurity risks are discussed with management for resolution planning and escalation. We leverage recognized cybersecurity frameworks to drive strategic direction and maturity improvement and engage third party security experts for risk assessments, risk mitigation actions, vulnerability identification, and program enhancements.
We periodically test our security controls through internal and external penetration testing that covers both corporate and plant IT networks by external specialized vendors, as well as in connection with auditing of our financial systems. We also conduct regular cybersecurity tabletop exercises to test established policies and procedures for responding to cybersecurity threats and incidents. In addition, we conduct an annual independent review of our cybersecurity posture.
Throughout the year, we conduct cybersecurity training and awareness for our employees to help identify, avoid and mitigate cybersecurity threats utilizing various delivery methods such as phishing campaigns, training sessions, and informational bulletins.
We conduct risk assessments of third-party suppliers and service providers including due diligence assessments of third-party suppliers and service providers that have access to the Company’s networks, confidential information, and information systems. We provide all third-party vendors, consultants, and partners with detailed security requirements for securing their connections into our IT networks. Third parties service providers are also typically contractually responsible for identifying and remediating security issues within their technology and service environment.
Management has not identified risks from cybersecurity threats, including as a result of any previous cybersecurity incidents, that have materially affected or are reasonably likely to materially affect the Company, including its business strategy, results of operations or financial condition. For more information, see “Item 1A. Risk Factors, Our operations have been and will continue to be subject to cyber-attacks and other disruptions to our information systems that could have a material adverse impact on our business, consolidated results of operations, and consolidated financial condition”.
Governance
The Board of Directors is responsible for overseeing the assessment and management of enterprise-level risks that may impact the Company. The Audit Committee has primary responsibility for overseeing risk management, including oversight of risks from cybersecurity threats. Management reports on cybersecurity matters, including material risks and threats, to the Audit Committee at regularly scheduled Audit Committee meetings, which is then discussed with the Board of Directors. The reports discuss specific risks and mitigation efforts, including critical and high cyber risks from the risk register, the results of our annual independent review of the Company’s cybersecurity posture and other third party assessments and benchmarking information.
It is management’s responsibility to manage cybersecurity risks, as described above, and bring to the Board’s attention material risks. Under the oversight of the Audit Committee, and as directed by the Company’s Chief Executive Officer, the Company’s Chief Information Officer (CIO) is primarily responsible for the assessment and management of cybersecurity risks. The CIO, who reports to the Chief Financial Officer, is aided by a third party Chief Information Security Officer with over 40 years of experience, in addition to other external professionals. Management’s risk oversight is also accomplished through the Company’s Strategic Risk Management Committee and Operating Risk Management Committee, which provides cross-functional support for cybersecurity risk management, as well as the Company’s Chief Compliance Officer.

Mining Properties
Information concerning our mining properties in this Annual Report on Form 10-K is disclosed in accordance with the requirements of subpart 1300 of Regulation S-K.
The Company relies on access to bentonite reserves to support our businesses. The Company has reserves of sodium and calcium bentonite at various locations in the U.S., including Wyoming, Montana, South Dakota, Nevada and Alabama, as well as in Australia, China, Slovakia and Turkey. Through the Company’s affiliations and joint ventures, the Company also has access to bentonite deposits in India and Mexico. The Company owns or controls the properties on which the bentonite reserves are located through long-term leases, royalty agreements (including easement and right of way agreements) and patented and unpatented mining claims. No single or group of mining claims or leases is significant or material to the financial condition or operations of our Company or our segments. The majority of our current bentonite mining in the U.S. occurs on reserves where our rights to such reserves accrue to us through over 80 mining leases and royalty agreements and 2,000 mining claims. A majority of these are with private parties and located in South Dakota, Montana and Wyoming. The bentonite deposits underlying these claims and leases generally lie in parcels of land varying between 20 and 40 acres.
In general, our bentonite reserves are immediately adjacent to, or within sixty miles of, one of the related processing plants. All of the properties on which our reserves are located are either physically accessible for the purposes of mining and hauling or the cost of obtaining physical access would not be material. Access to processing facilities from the mining areas is generally by private road, public highways, or railroads. For most of our leased properties and mining claims, there are multiple means of access.
Bentonite is surface mined, generally with large earthmoving bulldozers and scrapers, and then loaded into trucks and off-highway-haul wagons for movement to processing plants. The mining and hauling of our bentonite is done by us and by independent contractors. At the processing plants, bentonite is dried, crushed and sent through grinding mills, where it is sized to customer requirements, then chemically modified, where needed, and transferred to silos for automatic bagging or bulk shipment. Most of the production is shipped as processed rather than stored for inventory.
We also mine leonardite, a form of oxidized lignite, in North Dakota, and transport it to nearby processing facilities.
The Company’s Consumer & Specialties segment is supported by the Company’s limestone reserves located in the western and eastern parts of the United States. The Company generally owns and surface mines these reserves and processes its products at nearby processing plants.
The Company also owns mineral deposits that it is not currently mining, including deposits of bentonite in Nevada and chromite in South Africa, and leases its limestone mine in Pima, Arizona to a third party.
25

Below is a map of our significant mines globally.
Based upon the quantitative and qualitative factors applicable, we do not consider any of our mines to be individually material to the Company’s business or financial condition. The following provides an overview of the Company’s most significant mining properties and operations.
Colony, Wyoming Mines
The Company’s Colony, WY mining operations are located in the northern Black Hills in the tri-State area of South Dakota, Wyoming, and Montana, with processing facilities located in Colony, WY and Belle Fourche, SD.
The local processing facilities are supported by bentonite clay supplied from 53 million tons of proven and probable reserves, comprised of leases (71%), unpatented claims (22%), and owned properties (7%). The area operates under 12 mining permits covering approximately 100,000 acres, with active mining and future mineral reserves located within 35 miles of the Colony processing facilities.
The Black Hills are a northward-trending anticlinal uplift approximately 200 miles long and flank the Powder River Basin to the west and southwest, and the Williston Basin to the northeast. The bentonite clay in the Black Hills area is predominantly of the sodium type and was formed by the in-situ alteration of rhyolite volcanic ash.
Bentonite mining consists of shallow surface mining for bentonite beds located in the Mitten Black Shale, Gammon Ferruginous, Belle Fourche Shale, Green Horn Formations, Mowry, and Newcastle shales and sandstones. A back-cast method of mining is used whereby small pits are progressively opened and then quickly backfilled in succession as mining progresses along outcrops. The majority of pits are reclaimed in the same year that they were first disturbed.
Annual exploration and permitting activities target the replacement of the number of tons mined to support the long-term sustainability of local operations.
The Colony area mines are supported by 2 main processing plants located in Colony, WY. These plants produce both powder and granular products. A wet-processing facility is located near Belle Fourche, SD. All three facilities have direct access to rail.
26

Lovell, Wyoming Mines
The Company’s Lovell, WY mining operations are located in the Bighorn Basin near Lovell, WY with processing facilities located 3 miles East of the town of Lovell. One facility produces powder and granular bentonite products; the other facility produces geosynthetic clay liners and other environmental products. Both facilities have direct access to rail.
The Lovell processing facility is supported by bentonite clay supplied from 34 million tons of proven and probable reserves, comprised of leases (12%), unpatented claims (44%), and owned properties (44%). The area operates under 2 mining permits covering ~30,000 acres, with active mining and future mineral reserves located within 30 miles of the Lovell processing facilities.
The Bighorn Basin is a large sedimentary basin in northwestern Wyoming. It is Laramide in age and trends northwest-southeast. The bentonite clay in the Bighorn Basin is predominantly of the sodium type. Mining occurs from 19 different bentonite beds occurring in 3 geologic formations – the Thermopolis shale, the Mowry shale, and the Frontier shale which were deposited during the Upper Cretaceous Period between 70 to 100 million years ago. A back-cast method of mining is used whereby small pits are progressively opened and then quickly backfilled in succession as mining progresses along outcrops. Most pits are reclaimed in the same year that they were first disturbed.
Annual exploration and permitting activities target the replacement of the number of tons mined to support the long-term sustainability of local operations.
Ünye, Turkey Mines
The Company’s Unye-area mines, Nadirli and Konan, are located southwest of the town of Unye, Turkey on the southern coast of the Black Sea. These mines are operated by the Company via contract mining and hauling. Both mines use conventional open-pit truck & shovel mining methods. The properties are comprised of both government-issued mining claims and privately-owned lands. The orebodies were produced by hydrothermal alteration and generally occur as massive deposits greater than 10 meters in thickness. The bentonite ore is notable for its high brightness.
Ore from the mines is transported by truck to a processing facility in the town of Unye where it is stockpiled, dried, and converted to granular products.
Dongming, China Mines
The Company’s Dongming mines and processing facilities are located in Jianping county, Liaoning province, China. The regional bentonite occurs within the Jurassic Jingangshan and Tuhulu formations which were deposited during the Upper Jurassic Period between 135 to 144 million years ago. The thickness of the bentonite layers varies from 0.5 to 40m. The bentonite clay in the region is predominantly of the calcium type and is converted to sodium bentonite to produce the majority of products.
The Dongming mines consist of 16 small mining areas under 4 mining permits covering approximately 1,200 acres controlled by the Company. Rights to the bentonite are leased from the Chinese government and separate agreements are made with land owners for surface access and mining. Much of the bentonite supplied to the Dongming processing facility is from 3rd-party mines, with Company-controlled mines used to supplement supply and as strategic backup reserves. In most cases, supply from 3rd-party mines is directly supervised by local Company staff which assists with grading and quality control.
All mines are operated by contractors with conventional open-pit truck & shovel mining methods. Clay from the mines is hauled by trucks to the Company’s processing facility. The primary processing facility is located approximately 50 miles west of Chaoyang, Liaoning Province near the Dongming mines.
27

Adams, Massachusetts Mine
The Company’s Adams mine and the associated processing facility is located in the town of Adams, in the Northwest corner of Massachusetts. The property consists of approximately 800 total acres, including the land on which the production facilities sit. Production of lime began on the site back in the 1850s and continues today with GCC, Lime and PCC. The open-pit mine consists mainly of a mineral deposit of limestone (marble). The deposit is part of the Shelburne geological formation, which runs up and down the eastern coast of the United States.
The mined material is finely pulverized at the processing facility using a variety of crushing and milling equipment and sold as ground products, calcined into lime and is also synthesized into participated crystals or PCC. The resulting calcium and calcium carbonate products are primarily used as food and pharmaceutical ingredients, sealant additives, high-end construction ingredients, as well as asphalt roofing shingles.
The deposit is wholly owned by the Company.
With over 150 years of mining on site by the Company and its predecessors, the resources are well understood. A mine plan has been developed based on the prior mining activities and a core drilling program was completed in 2019. The reserves and resources are the product of this recent life-of-mine study.
Canaan, Connecticut Mine
The Canaan mine and the associated processing facility are located in the town of North Canaan, Connecticut and consists of approximately 208 total acres.  The mine is situated between Canaan Mountain to the South and Lower Road to the North.  The mine is located approximately 1.0 miles south of the main processing facility.
The open-pit mine consists mainly of dolomitic limestone.  The mined dolomite is finely pulverized at the processing facility using a variety of crushing and milling equipment.  The resulting Ground Calcium Carbonate (GCC) is primarily used by high-end, high-volume construction markets in joint compound, floor coverings, asphalt roofing shingles and glass.

(1) | Certain definitions:

The term “mineral resource” indicates a concentration or occurrence of material of economic interest in or on the Earth’s crust in such form, grade or quality, and quantity that there are reasonable prospects for economic extraction.
The term “measured resource” indicates a mineral resource for which quantity and grade or quality are estimated based on conclusive geological evidence and sampling.
The term “indicated resource” indicates a mineral resource for which quantity and grade or quality are estimated based on adequate geological evidence and sampling.
The term “inferred resource” indicates a mineral resource for which quantity and grade or quality are estimated based on limited geological evidence and sampling.

(2) | Mineral resources estimates were calculated and prepared by the Company’s in-house technical staff.

(3) | Quantity of resources that would be owned if patent was granted.

The estimates of total reserves and resources noted in the tables above require the Company to make certain key assumptions. These assumptions relate to consistency of deposits in relation to drilling samples obtained with respect to both quantity and quality of reserves contained therein; the ratio of overburden to mineral deposits; any environmental or social impact of mining the minerals; and profitability of extracting those minerals, including haul distance to processing plants, applicability of minerals to various end markets and selling prices within those markets, and our past experiences in the deposits, several of which we have been operating in for many decades.
31

The Company maintains a Mining Lead Team that develops standards and systems to ensure Company-wide use of best practices for mining and exploration. The Mining Lead Team ensures that the Company maintains robust controls over its exploration and resource and reserve estimation efforts. In particular, because the Company has a long history of operations at its mining operations, the Company is able to continuously validate its resource and reserve estimates by reference to actual production from each mine. During the process from exploration to final production, ore is tested a minimum of 3 times beginning with exploration drilling, again after overburden removal and finally on finished products after plant processing. In some cases when blending ore grades, an additional step of testing occurs on stockpiles after hauling from the mine but before plant processing. The quantities, qualities, and costs of grades obtained from mining and processing are reconciled to quantities, qualities, and costs from reserve estimates and mine models. To enable additional verification of reserves if needed, all exploration samples are retained until areas are mined out and reclaimed.
The Company believes that its facilities, which are of varying ages and are of different construction types, have been satisfactorily maintained, are in good condition, are suitable for the Company’s operations and generally provide sufficient capacity to meet the Company’s production requirements. Based on past loss experience, the Company believes it is adequately insured with respect to these assets and for liabilities likely to arise from its operations.
The Company holds numerous environmental and mineral extraction permits, water rights and other permits, licenses and approvals from governmental authorities authorizing operations at each of our mines. Permits, licenses and approvals are obtained as needed in the normal course of business based on our mine plans and applicable regulatory provisions regarding mine permitting and licensing. Based on our historical permitting experience, we expect to be able to continue to obtain necessary mining permits and approvals to support historical rates of production.
Assuming the continuation of 2024 annualized usage rates, the Company has reserves of commercially usable sodium bentonite in excess of 50 years, commercially usable calcium bentonite for the next 15 years and commercially usable leonardite for more than 50 years. At current usage levels, the Company has reserves in excess of 28 years at its limestone production facilities.
The Company has ongoing exploration and development activities for all of its mineral interests with the intent to increase its proven and probable reserves.
Item 3. Legal Proceedings
From time to time, the Company and its subsidiaries are the subject of various legal actions and claims arising in the ordinary course of their businesses. The most significant litigation facing the Company is the asbestos-related Chapter 11 cases of BMI Oldco Inc. (f/k/a Barretts Minerals Inc.) and Barretts Ventures Texas LLC. Additional information regarding legal proceedings is disclosed in Note 17 to the consolidated financial statements included elsewhere in this report, which disclosure is incorporated herein by reference.
Item 4. Mine Safety Disclosures
The information concerning mine safety violations or other regulatory matters required by Section 1503(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 104 of Regulation S-K is included in Exhibit 95 to this Annual Report on Form 10-K.

(f/k/a Barretts Minerals Inc.) ("Oldco") and Barretts Ventures Texas LLC ("BVT" and together with Oldco, the "Chapter 11 Debtors"). In addition, in 2024, the Company entered into a Debtor-in-Possession Credit Agreement with Oldco (the "DIP Credit Agreement") which resulted in a $30.0 million provision for credit loss charge. The Company also recorded a $12.3 million net gain on the sale of assets relating to a facility in the Engineered Solutions segment in 2024. Included in income from operations in 2023 was a $71.7 million non-cash impairment charge for Oldco's fixed assets and $29.2 million of litigation expenses in connection with Oldco's bankruptcy filing and by Oldco to defend against and restore its reserve for claims associated with certain talc products.

In connection with the refinancing, the Company incurred $1.8 million of debt extinguishment expenses.
In 2024, the Company continued to deliver on its strategic growth initiatives driven by multi-year advancements in new product development, positioning in growth markets and geographies, geographic penetration and growth from acquisitions.
Our balance sheet continues to be strong. Cash, cash equivalents and short-term investments were $337.1 million as of December 31, 2024. Cash flow from operations for 2024 was $236.4 million. The Company currently has more than $700 million of available liquidity, including cash on hand, as well as availability under its revolving credit facility. We believe these factors will allow us to meet our anticipated funding requirements. Our intention is to maintain a balanced approach to capital deployment, by using cash flow for investments in growth, returns to shareholders, and continued debt reduction.

Such credit loss is not currently deductible as the loans under such agreement are treated as an equity contribution for tax purposes. The current expected credit loss may become fully deductible in a future period. The timing of such deductibility is dependent on developments in the bankruptcy proceedings.
The higher effective tax rate in 2023 as compared to 2022 was primarily due to the impact of rate differentials related to foreign earnings indefinitely invested.
The other factors having the most significant impact on our effective tax rates in recent periods are percentage depletion, the Global Intangible Low-Tax Income provision ("GILTI"), Foreign-Derived Intangible Income (“FDII”), 162(m) disallowance, and the tax benefits on restructuring and impairment charges.
Percentage depletion allowances (tax deductions for depletion that may exceed our tax basis in our mineral reserves) are available to us under the income tax laws of the United States for operations conducted in the United States. The tax benefits from percentage depletion were $10.0 million in 2024, $11.1 million in 2023 and $9.6 million in 2022.
The Company has elected, as its accounting policy, to treat the taxes due from GILTI as a current period expense when incurred. The net charge to the Company for GILTI was $1.5 million, $1.1 million and $3.5 million for 2024, 2023 and 2022, respectively.
We operate in various countries around the world that have tax laws, tax incentives and tax rates that are significantly different than those of the United States. These differences combine to move our overall effective tax rate higher or lower than the United States statutory rate depending on the mix of income relative to income earned in the United States. The effects of foreign earnings and the related foreign rate differentials resulted in increases of $10.5 million, $8.2 million and $3.8 million in 2024, 2023 and 2022, respectively.
In December 2021, as part of the Organization for Economic Co-operation and Development’s (“OECD”) Inclusive Framework, 140 member countries agreed to the implementation of the Pillar Two Global Minimum Tax (“Pillar 2”). The Company began implementation of the Pillar 2 Model Rules in the first quarter of 2024. The Company continues to assess the effect of the Pillar 2 rules in all jurisdictions and does not expect that Pillar 2 will have a material impact on its consolidated financial statements.
Consolidated Net Income Attributable to MTI Shareholders
Consolidated net income was $170.9 million in 2024 and included a $31.7 million charge, net of tax. This charge consisted of a provision for credit loss and litigation expenses, offset by a gain on a sale of assets.
Consolidated net income was $88.3 million in 2023 and included a $85.8 million charge, net of tax. This charge consisted of impairment of assets, litigation expenses, restructuring and acquisition-related expenses.

2024 v 2023
Net sales in the Consumer & Specialties segment decreased 1.7% to $1,140.2 million, as compared with $1,160.2 million in the prior year. Household & Personal Care sales increased 2.4% to $530.0 million from $517.6 million the prior year. This increase was primarily driven by strong demand for our pet litter products in all regions and growth in other high-margin consumer-oriented products. Specialty Additives sales decreased 5.0% to $610.2 million from $642.6 million primarily as a result of the deconsolidation of Oldco in the fourth quarter of 2023. Included in Specialty Additives' sales from the prior year were $40.6 million of sales related to Oldco.
42

Income from operations was $165.5 million in 2024, as compared to $41.6 million in 2023. In 2023, the Company recorded a $71.7 million non-cash impairment of Oldco's fixed assets and litigation expenses of $29.2 million in connection with Oldco's bankruptcy filing and by Oldco to defend against and restore its reserve for claims associated with certain talc products.
2023 v 2022
Net sales in the Consumer & Specialties segment increased 3.2% to $1,160.2 million, as compared with $1,124.6 million in the prior year. Household & Personal Care sales increased 8.7% to $517.6 million from $476.2 million in the prior year. This increase was primarily driven by strong demand for our pet litter products in all regions and growth in other high-margin consumer-oriented products. Specialty Additives sales decreased 0.9% to $642.6 million from $648.4 million primarily as a result of the deconsolidation of Oldco in the fourth quarter of 2023. Sales for Oldco in the fourth quarter of 2022 were $12.0 million.
Income from operations was $41.6 million in 2023, as compared to $79.0 million in 2022. In 2023, the Company recorded a $71.7 million non-cash impairment of assets related to Oldco. In addition, litigation expenses of $29.2 million and $32.6 million were recorded in 2023 and 2022, respectively, relating to Oldco.

% of net sales |  |  | 17.8 | % |  |  | 14.6 | % |  |  | 14.7 | % |  |  |  |  |  |  |  |

2024 v 2023
Net sales in the Engineered Solutions segment decreased 3.1% to $978.3 million, as compared with $1,009.7 million in the prior year. High-Temperature Technologies sales decreased 1.1% to $713.2 million, as compared with $720.9 million in the prior year. This decrease was driven by softer demand in some industrial end markets. Environmental & Infrastructure sales decreased 8.2% to $265.1 million, as compared with $288.8 million in the prior year as a result of low levels of project activity.
Income from operations was $174.0 million and 17.8% of sales, as compared with $147.8 million and 14.6% of sales in the prior year. Included in income from operations for 2024 is a $12.3 million net gain on sale of assets. Included in income from operations for 2023 are $3.2 million of restructuring expenses.
2023 v 2022
Net sales in the Engineered Solutions segment increased 0.9% to $1,009.7 million, as compared with $1,000.9 million in the prior year. High-Temperature Technologies sales increased 2.6% to $720.9 million, as compared with $702.5 million in the prior year. This increase was driven by strong demand in the North America market and volume recovery in China. Environmental & Infrastructure decreased 3.2% to $288.8 million, as compared with $298.4 million in the prior year. This decrease is a result of weak commercial construction activity in 2023.
Income from operations was $147.8 million and 14.6% of sales, as compared with $147.1 million and 14.7% of sales in the prior year. Included in income from operations for 2023 are $3.2 million of restructuring expenses.
Inflation
While inflation historically has not had a material impact on the Company, our financial performance could be adversely affected by increases in energy and commodity prices. Our production processes consume a significant amount of energy, primarily electricity, diesel fuel, natural gas and coal. We use diesel fuel to operate our mining and processing equipment and our freight costs are heavily dependent upon fuel prices and surcharges. Energy costs also affect the cost of raw materials. On a combined basis, these factors represent a large exposure to petrochemical and energy products which may be subject to significant price fluctuations. The contracts pursuant to which we construct and operate our satellite PCC plants generally adjust pricing to reflect the pass-through of increases in costs resulting from inflation, including lime and energy prices. However, there is a time lag before such price adjustments can be implemented. The Company and its customers will typically negotiate reasonable price adjustments in order to recover a portion of these escalating costs, but there can be no assurance that we will be able to recover increasing costs through such negotiations.
43

Cyclical Nature of Customers’ Businesses
Portions of our sales to customers in the paper manufacturing, metalcasting, steel manufacturing, oil and gas and construction industries have historically been cyclical. The pricing structure of some of our long-term PCC contracts makes our PCC business less sensitive to declines in the quantity of product purchased. Oil and natural gas prices decreased significantly between 2014 through 2017 and again in 2020, which has caused exploration companies to reduce their capital expenditures and production and exploration activities. This has had the effect of decreasing the demand and increasing competition for the services we provide. We cannot predict the economic outlook in the countries in which we do business, nor in the key industries we serve.
Liquidity and Capital Resources
Cash provided from continuing operations in 2024 was $236.4 million, compared with $233.6 million in prior year. Cash flows provided from operations in 2024 were principally used to fund capital expenditures, repay debt, repurchase shares and to pay the Company’s dividend to common shareholders. The Company’s intention is to use cash flow for investments in growth, returns to shareholders, and continued debt reduction.
On November 26, 2024, the Company, entered into a Refinancing Facility Agreement and Incremental Facility Amendment (the “Amendment”) to amend the Company's previous credit agreement (the "Previous Credit Agreement; the previous credit agreement, as amended by the Amendment, being the "Amended Credit Agreement"). The Amendment provides for, among other things, a new senior secured revolving credit facility with aggregate commitments of $400 million (the “Revolving Facility”), a portion of which may be used for the issuance of letters of credit and swingline loans, and a new senior secured term loan facility with aggregate commitments of $575 million (the “Term Loan Facility” and, together with the Revolving Facility, the "Senior Secured Credit Facilities"). The Revolving Facility and the Term Loan Facility replace the facilities under the Previous Credit Agreement, which provided for, among other things, a $550 million senior secured term loan facility and a $300 million senior secured revolving credit facility. The maturity date for loans and commitments under the Revolving Facility is November 26, 2029, and the maturity date for loans under the Term Loan Facility is November 26, 2031; provided that the maturity dates of the Revolving Facility and the Term Loan Facility will be adjusted to the date that is 91 days prior to the stated maturity date of the Company’s 5.0% Senior Notes due 2028 (the “Notes”) unless, prior to the date that is 91 days prior to the stated maturity date of the Notes, all amounts in excess of $50 million of the Notes have been either (a) refinanced with indebtedness permitted under the Amended Credit Agreement maturing later than 90 days after the scheduled maturity date of the Revolving Facility or of the Term Loan Facility, as applicable, or (b) repaid, discharged or repaid (other than with the proceeds of any indebtedness maturing earlier than 91 days after the scheduled maturity date of the Revolving Facility or of the Term Loan Facility, as applicable). Loans under the Term Loan Facility amortize at a rate equal to 1.00% per annum, payable in equal quarterly instalments, and were issued with original issue discount at 99.875% of par.
Loans under the Revolving Facility will bear interest at a rate equal to (a) for loans denominated in U.S. dollars, at the election of the Company, Term SOFR plus an applicable margin equal to 1.375% per annum or a base rate plus an applicable margin equal to 0.375% per annum, (b) for loans denominated in Euros, adjusted EURIBOR plus an applicable margin equal to 1.375% per annum and (c) for loans denominated in Pounds Sterling, SONIA plus an applicable margin equal to 1.375% per annum, subject in each case to (i) an increase of 37.5 basis points in the event that, and for so long as, the Net Leverage Ratio (as defined in the Amended Credit Agreement) is greater than or equal to 3.00 to 1.00 as of the last day of the preceding fiscal quarter, (ii) an increase of 12.5 basis points in the event that, and for so long as, the Net Leverage Ratio is less than 3.00 to 1.00 and greater than or equal to 2.00 to 1.00 as of the last day of the preceding fiscal quarter and (iii) a decrease of 12.5 basis points in the event that, and for so long as, the Net Leverage Ratio is less than 1.00 to 1.00 as of the last day of the preceding fiscal quarter. Loans under the Term Loan Facility will bear interest at a rate equal to, at the election of the Company, Term SOFR plus an applicable margin equal to 2.00% per annum or a base rate plus an applicable margin equal to 1.00% per annum. The Company will pay certain fees under the Amended Credit Agreement, including (a) a commitment fee of 0.175% per annum on the undrawn portion of the Revolving Facility (subject to a step-ups to 0.300% and 0.250% and a step-down to 0.150% at the same levels described above), (b) a fronting fee of 0.125% per annum on the average daily undrawn amount of, plus unreimbursed amounts in respect of disbursements under, letters of credit issued under the Revolving Facility and (c) customary annual administration fees. The obligations of the Company under the Senior Secured Credit Facilities are unconditionally guaranteed jointly and severally by, subject to certain exceptions, all material domestic subsidiaries of the Company (the “Guarantors”) and secured, subject to certain exceptions, by a security interest in substantially all of the tangible and intangible assets of the Company and the Guarantors.
In the fourth quarter of 2024, the Company recorded $1.8 million in non-cash debt extinguishment expenses related to the refinancing of our credit facilities, which represents the difference between the redemption payment and the carrying value of the debt at the refinancing date. All lenders under the previous facility were repaid in full.
As of December 31, 2024, there were $4.5 million in loans and $9.1 million in letters of credit outstanding under the Revolving Facility.
44

On June 30, 2020, the Company issued $400 million aggregate principal amount of Notes. The Notes were issued pursuant to an indenture, dated as of June 30, 2020, between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Indenture”). The Notes bear an interest rate of 5.0% per annum payable semi-annually on January 1 and July 1 of each year, beginning on January 1, 2021. The Notes are unconditionally guaranteed on a senior unsecured basis by each of the Company’s existing and future wholly owned domestic restricted subsidiaries that is a borrower under or that guarantees the Company’s obligations under its Senior Secured Credit Facilities or that guarantees the Company’s or any of the Company’s wholly owned domestic subsidiaries’ long-term indebtedness in an aggregate amount in excess of $50 million.
The Company may redeem some or all of the Notes at any time and from time to time at the applicable redemption prices listed in the Indenture, plus accrued and unpaid interest, if any, to, but excluding, the applicable redemption date.
If the Company experiences a change of control (as defined in the indenture), the Company is required to offer to repurchase the Notes at 101% of the principal amount of such Notes, plus accrued and unpaid interest, if any, to, but excluding, the date of repurchase.
The Amended Credit Agreement and the Indenture both contain certain customary affirmative and negative covenants that limit or restrict the ability of the Company and its restricted subsidiaries to enter into certain transactions or take certain actions, as well as customary events of default. In addition, the Amended Credit Agreement contains a financial covenant that requires the Company to maintain a maximum Net Leverage Ratio of 4.00 to 1.00 for each four fiscal quarter period (subject to an increase to 5.00 to 1.00 for four quarters in connection with certain significant acquisitions).
The Company has a committed loan facility in Japan. As of December 31, 2024, there was an outstanding balance of $0.9 million on this facility. Principal will be repaid in accordance with the payment schedule ending in 2026. The Company repaid $0.4 million on these loans in 2024.
As part of the Concept Pet acquisition, the Company assumed $1.9 million in long-term debt, recorded at fair value, consisting of two terms loans, one that matures in 2025 and one that matures in 2027. Both loans have annual payments and carry a variable interest rate. The Company repaid $0.3 million on these loans during 2024.
As of December 31, 2024, the Company had $24.3 million in uncommitted short-term bank credit lines, $0.6 million of which were in use. The credit lines are primarily outside the U.S. and are generally one year in term at competitive market rates at large, well-established institutions. The Company typically uses its available credit lines to fund working capital requirements or local capital spending needs. We anticipate that capital expenditures for 2025 should be between $90 million and $100 million, principally related to opportunities to improve our operations and meet our strategic growth objectives. We expect to meet our other long-term financing requirements from internally generated funds and committed and uncommitted bank credit lines.
In the second quarter of 2023, the Company entered into a floating to fixed interest rate swap for a notional amount of $150 million. The fair value of this instrument as of December 31, 2024 is an asset of $0.3 million.
In addition to long-term debt, the Company has committed cash outflow related to pension and post-retirement benefit obligations, non-cancelable operating leases, primarily for office space and equipment, and other long-term contractual obligations. Other long-term liabilities include tax liabilities, including contingent obligations associated with gross unrecognized tax benefits for uncertain tax positions and a tax liability for the one-time transition tax on accumulated foreign subsidiary earnings, asset retirement obligations relating to the retirement of certain tangible long-lived assets and land restoration obligations at the Company’s PCC satellite facilities and mining operations. See Notes 2, 8, 15, 16 and 20 to the Consolidated Financial Statements.
On October 18, 2023, the Company’s Board of Directors authorized the Company’s management to repurchase, at its discretion, up to $75 million of the Company’s shares over a one-year period. Over this program's one-year period, 1,034,692 shares have been repurchased under this program for $75 million, or an average price of approximately $72.48 per share. This program is now complete.
On October 16, 2024, the Company's Board of Directors authorized the Company's management to repurchase, at its discretion, up to $200 million of the Company's shares. As of December 31, 2024, 34,934 shares have been repurchased under this program for $2.8 million, or an average price of approximately $79.27 per share. This authorization has no expiration date.
45

On January 22, 2025, the Company’s Board of Directors declared a regular quarterly dividend on its common stock of $0.11 per share. No dividend will be payable unless declared by the Board and unless funds are legally available for payment thereof.
The Company and certain of the Company’s subsidiaries are among numerous defendants in over six hundred cases seeking damages for alleged exposure to asbestos-contaminated talc products sold by the Company’s subsidiary Oldco. The Company’s position is that these cases are meritless and all talc products sold by Oldco are safe. On October 2, 2023 (the “Petition Date”), notwithstanding the Company’s confidence in the safety of Oldco’s talc products, the Chapter 11 Debtors filed voluntary petitions for relief under Chapter 11 of the U.S. Bankruptcy Code in the United States Bankruptcy Court for the Southern District of Texas (the “Chapter 11 Cases”) to address and comprehensively resolve Oldco’s liabilities associated with talc. Minerals Technologies Inc. and the Company’s other subsidiaries were not included in the Chapter 11 filing. In the second quarter of 2024, Oldco sold its talc assets under section 363 of the U.S. Bankruptcy Code. In addition, in the second quarter of 2024, the Company entered into a Debtor-in-Possession Credit Agreement with Oldco (the "DIP Credit Agreement") and recorded a provision for credit loss of $30 million for the maximum principal amount under such DIP Credit Agreement. Proceeds of the sale of Oldco's talc assets, as well as the funds drawn by Oldco under the DIP Credit Agreement, will be used to fund the Chapter 11 Cases. The Chapter 11 Debtors' ultimate goal in the Chapter 11 Cases is to confirm a plan of reorganization under Section 524(g) of the U.S. Bankruptcy Code and utilize this provision of the Bankruptcy Code to establish a trust that will address all current and future talc-related claims. In January 2024, the Chapter 11 Debtors and Minerals Technologies Inc. commenced a court-approved mediation process with the Official Committee of Unsecured Creditors (appointed in the Chapter 11 Cases as the representative of current talc claimants) and the Future Claimants Representative (appointed in the Chapter 11 Cases as the representative of future talc claimants) regarding the terms of a potential consensual plan of reorganization and the ultimate amount to be contributed to any trust. The mediation process is ongoing. During the pendency of the Chapter 11 Cases, the Company anticipates that the Chapter 11 Debtors will benefit from the operation of the automatic stay, which stays ongoing litigation in connection with talc-related claims against Oldco. In addition, subject to certain exceptions, the filing or continued prosecution of all talc-related claims against Oldco’s non-debtor affiliates is temporarily stayed through April 15, 2025 (subject to further extensions), the date on which a hearing is scheduled on the status of the Chapter 11 Cases. The Chapter 11 Debtors have been deconsolidated from the Company’s financial statements since the Petition Date. Although the Chapter 11 Cases are progressing, it is not possible to predict the form of any ultimate resolution or when an ultimate resolution might occur at this time. Accordingly, the amount that will be necessary to fully and finally resolve all of the Chapter 11 Debtors' current and future talc-related claims in connection with a confirmed Chapter 11 plan of reorganization cannot be estimated with certainty at this time. See Note 17 to the consolidated financial statements included in this report for more information.
Critical Accounting Policies and Estimates
Our 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 U.S. generally accepted accounting principles. 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 disclosure of contingent assets and liabilities.
On an ongoing basis, we evaluate our estimates and assumptions, including those related to revenue recognition, valuation of long-lived assets, goodwill and other intangible assets, income taxes, including valuation allowances and pension plan assumptions. We base our estimates on historical experience and on other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that cannot readily be determined from other sources. There can be no assurance that actual results will not differ from those estimates.
We believe the following critical accounting policies require us to make significant judgments and estimates in the preparation of our consolidated financial statements.
Revenue Recognition
Revenue is recognized at the point in time when the customer obtains control of the promised goods or services in an amount that reflects the consideration we expect to receive in exchange for those goods or services. The Company’s revenues are primarily derived from the sale of products. Our primary performance obligation is satisfied upon shipment or delivery to our customer based on written sales terms, which is also when control is transferred. Revenue, where our performance obligations are satisfied in phases, is recognized over time using certain input measures based on the measurement of the value transferred to the customer, including milestones achieved. Revenues from sales of equipment are recorded upon completion of installation and transfer of control to the customer. Revenues from services are recorded when the services are performed.
46

In most of our PCC contracts, the price per ton is based upon the total number of tons sold to the customer during the year. Under those contracts, the price billed to the customer for shipments during the year is based on periodic estimates of the total annual volume that will be sold to the customer. Revenues are adjusted at the end of each year to reflect the actual volume sold. There were no significant revenue adjustments in the fourth quarter of 2024 and 2023, respectively. We have consignment arrangements with certain customers in our Engineered Solutions segment. Revenues for these transactions are recorded when the consigned products are consumed by the customer.
Allowance for Credit Losses
The allowance for credit losses (ACL) is management's estimate of the current expected credit losses at the balance sheet date. Our credit exposure includes an unfunded load commitment. For this exposure, we recognized an ACL associated with the unfunded amount, which is reported as a liability in accrued expenses and other current liabilities on our consolidated balance sheet.
Valuation of Long-lived Assets, Goodwill and Other Intangible Assets
We assess the possible impairment of long-lived assets and identifiable amortizable intangibles whenever events or changes in circumstances indicate that the carrying value may not be recoverable.
Goodwill is evaluated for impairment at least annually. Factors we consider important that could trigger an impairment review include the following:

| ● | Significant under-performance relative to historical or projected future operating results;

| ● | Significant changes in the manner of use of the acquired assets or the strategy for the overall business;

| ● | Significant negative industry or economic trends;

| ● | Market capitalization below invested capital.

Annually, the Company performs a qualitative assessment for each of its reporting units to determine if the two-step process for impairment testing is required. If the Company determines that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the Company then evaluates the recoverability of goodwill using a two-step impairment test approach at the reporting unit level. Step one involves a) developing the fair value of total invested capital of each reporting unit in which goodwill is assigned; and b) comparing the fair value of total invested capital for each reporting unit to its carrying amount, to determine if there is goodwill impairment. Should the carrying amount for a reporting unit exceed its fair value, then the step one test is failed, and the magnitude of any goodwill impairment is determined under step two. The amount of impairment loss is determined in step two by comparing the implied fair value of reporting unit goodwill with the carrying amount of goodwill.
The Company has two reporting units; Consumer & Specialties and Engineered Solutions. We identify our reporting units by assessing whether the components of our operating segments constitute businesses for which discrete financial information is available, and management regularly reviews the operating results of those components. In the fourth quarter of 2024, the Company performed a qualitative assessment of each of its reporting units and determined it was not more likely than not that the fair value of any of its reporting units was less than their carrying values.
Property, plant and equipment are depreciated over their useful lives. Useful lives are based on management’s estimates of the period that the assets can generate revenue, which does not necessarily coincide with the remaining term of a customer’s contractual obligation to purchase products made using those assets. Our sales of PCC are predominately pursuant to long-term evergreen contracts, initially ten years in length, with paper mills at which we operate satellite PCC plants. The terms of many of these agreements have been extended, often in connection with an expansion of the satellite PCC plant. Failure of a PCC customer to renew an agreement or continue to purchase PCC from our facility could result in an impairment of assets or accelerated depreciation at such facility.
We evaluate the recoverability of our property, plant and equipment whenever events or change in circumstances indicate that the carrying value of the assets may not be recoverable. For testing the recoverability, we primarily use discounted cash flow models or cost approach to estimate the fair value of these assets. Critical assumptions used in conducting these tests included expectations of our business performance and financial results, useful lives of assets, discount rates and comparable market data.
47

When we acquire a company, we determine fair value on the acquisition date of assets acquired and liabilities assumed. We use the income, market or cost approach (or a combination thereof) for the valuation and use valuation inputs and analyses that are based on market participant assumptions. Changes in assumptions can have a significant impact on the fair value of tangible assets. Goodwill is calculated as the excess of the consideration transferred over the assets acquired and represents the estimated future economic benefits arising from other assets acquired that could not be individually identified and separately recognized.
Income Taxes
As part of the process of preparing our consolidated financial statements, we are required to estimate our income taxes in each of the jurisdictions in which we operate. This process involves estimating current tax expense together with assessing temporary differences resulting from differing treatments of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included in the consolidated balance sheet. We must then assess the likelihood that our deferred tax assets will be recovered from future taxable income, and to the extent we believe that recovery is not likely, we must establish a valuation allowance. To the extent we establish a valuation allowance or change this allowance in a period, we must include an expense within the tax provision in the Consolidated Statements of Income.
Deferred tax liabilities represent the amount of income taxes payable in future periods. Such liabilities arise because of temporary differences between the financial reporting and tax bases of assets and liabilities. Deferred income tax assets represent amounts available to reduce income taxes payable on taxable income in future years. Such assets arise because of temporary differences between the financial reporting and tax bases of assets and liabilities, as well as from net operating losses. We evaluate the recoverability of these future tax deductions by assessing the adequacy of future expected taxable income from all sources, including reversal of taxable temporary differences and forecasted operating earnings. These sources of income inherently rely heavily on estimates. We use our historical experience and business forecasts to provide insight. The amount recorded for the net deferred tax liability was $115.7 million and $123.3 million at December 31, 2024 and 2023, respectively.
The application of income tax law is inherently complex. Laws and regulations in this area are voluminous and are often ambiguous. As such, we are required to make many subjective assumptions and judgments regarding our income tax exposures. Interpretations of and guidance surrounding income tax laws and regulations change over time. As such, changes in our subjective assumptions and judgments can materially affect the amounts recognized in the consolidated balance sheets and statements of operations. See Note 8 to the Consolidated Financial Statements for additional details on our uncertain tax positions.
Pension Benefits
We sponsor pension and other retirement plans in various forms covering the majority of employees who meet eligibility requirements. Several statistical and actuarial models which attempt to estimate future events are used in calculating the expense and liability related to the plans. These models include assumptions about the discount rate, expected return on plan assets and the rate of future compensation increases as determined by us, within certain guidelines. Our assumptions reflect our historical experience and management’s best judgment regarding future expectations. In addition, our actuarial consultants also use subjective factors such as withdrawal and mortality rates to estimate these assumptions. The actuarial assumptions used by us may differ materially from actual results due to changing market and economic conditions, higher or lower withdrawal rates, or longer or shorter life spans of participants, among other things.
The investment strategy for pension plan assets is to maintain a broadly diversified portfolio designed to both preserve and grow plan assets to meet future plan obligations. The Company’s average rate of return on assets from inception through December 31, 2024 was approximately 9%. The Company’s assets are strategically allocated among equity, debt and other investments to achieve a diversification level that dampens fluctuations in investment returns. The Company’s long-term investment strategy is an investment portfolio mix of approximately 55%-65% in equity securities, 30%-35% in fixed income securities and 0%-15% in other securities. As of December 31, 2024, the Company had approximately 55% of its pension assets in equity securities, 33% in fixed income securities and 12% in other securities.
The Company recognized pension expense of $1.9 million in 2024 as compared to $5.7 million in 2023. Accounting guidance on retirement benefits requires companies to discount future benefit obligations back to today’s dollars using a discount rate that is based on high-quality fixed-income investments. A decrease in the discount rate increases the pension benefit obligation, while an increase in the discount rate decreases the pension benefit obligation. This increase or decrease in the pension benefit obligation is recognized in Accumulated other comprehensive income (loss) and subsequently amortized into earnings as an actuarial gain or loss. The guidance also requires companies to use an expected long-term rate of return on plan assets for computing current year pension expense. Differences between the actual and expected returns are also recognized in Accumulated other comprehensive income (loss) and subsequently amortized into earnings as actuarial gains and losses. At the end of 2024, total actuarial losses recognized in Accumulated other comprehensive loss for pension plans were $1.3 million as compared to $32.1 million in 2023.
48

A net gain of $40.6 million ($30.6 million after-tax) primarily due to actuarial gains, driven by a change in discount rates is included in other comprehensive income in 2024. In 2023, a net gain of $7.6 million ($5.6 million after-tax) was recorded in other comprehensive income, primarily due to actuarial gains, driven by a change in discount rates. In 2022, a net gain of $46.3 million ($35.3 million after-tax) was recorded in other comprehensive income, primarily due to a change in discount rates.
Actuarial losses for pensions will be impacted in future periods by actual asset returns, discount rate changes, actual demographic experience and other factors that impact these expenses. These losses, reported in Accumulated other comprehensive income (loss), will generally be amortized as a component of net periodic benefit cost on a straight-line basis over the average remaining service period of active employees expected to receive benefits under the benefit plans. At the end of 2024, the average remaining service period of active employees or life expectancy for fully eligible employees was 9 years.
For a detailed discussion on the application of these and other accounting policies, see “Summary of Significant Accounting Policies” in Note 1 to the Consolidated Financial Statements. This discussion and analysis should be read in conjunction with the consolidated financial statements and related notes included elsewhere in this report.
Recently Issued Accounting Standards
Changes to accounting principles generally accepted in the United States of America (U.S. GAAP) are established by the Financial Accounting Standards Board (FASB) in the form of accounting standards updates (ASUs) to the FASB’s Accounting Standards Codification. The Company considers the applicability and impact of all ASUs. ASUs not listed below were assessed and determined to be either not applicable or are expected to have a minimal impact on our consolidated financial position and results of operations.
Adoption of Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures
In November 2023, the FASB issued ASU 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures”, which requires entities to report incremental information about significant segment expenses included in a segment’s profit or loss measure, as well as the name and title of the chief operating decision maker. The guidance also requires interim disclosures related to reportable segment profit or loss and assets that had previously only been disclosed annually. The new standard is effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2023. The Company adopted this guidance on January 1, 2024 and updated the disclosures contained in Note 21. This guidance did not impact the Company's consolidated financial statements.
Income Taxes (Topic 740): Improvements to Income Tax Disclosures
In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures”, that requires entities to disclose additional information about federal, state, and foreign income taxes primarily related to the income tax rate reconciliation and income taxes paid. The new standard also eliminates certain existing disclosure requirements related to uncertain tax positions and unrecognized deferred tax liabilities. The new standard is effective for interim and annual periods beginning on or after December 15, 2024. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements but will result in disaggregation of the Company's tax footnote.
Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses
In November 2024, the FASB issued ASU 2024-03, “Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses”, that requires entities to disclose additional information in the notes to the financial statements about prescribed categories underlying any relevant income statement expense caption. The new standard is effective for annual periods beginning after December 15, 2026 and interim periods within fiscal years beginning after December 15, 2027. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements.
Item 7A. Quantitative and Qualitative Disclosures about Market Risk
We are exposed to market risk from fluctuations in foreign currency exchange rates, interest rates and credit risk. We use a variety of practices to manage these market risks, including derivative financial instruments when appropriate. Our treasury and risk management policies prohibit us from using derivative instruments for trading or speculative purposes. We also do not use leveraged derivative instruments or derivatives with complex features.
Exchange Rate Sensitivity
As we operate in over 30 countries with many international subsidiaries, we are exposed to currency fluctuations related to manufacturing and selling our products and services. This foreign currency risk is diversified and involves assets, liabilities and cash flows denominated in currencies other than the U.S. Dollar (USD).
49

We manage our foreign currency exchange risk in part through operational means, including managing the same currency revenues versus same currency costs, as well as, same currency assets versus same currency liabilities. We also have subsidiaries with the same currency exposures which may offset each other, providing a natural hedge against one another’s currency risk. When appropriate, we enter into derivative financial instruments, such as forward exchange contracts and cross currency interest rate swaps, to mitigate the impact of foreign exchange rate movements on our operating results. The counterparties are major financial institutions. Such forward exchange contracts would not subject us to additional risk from the exchange rate because gains and losses on these contracts would offset losses and gains on the assets, liabilities, and transactions being hedged.
Assets and liabilities of our international subsidiaries are translated to their parent company’s reporting currency at current exchange rates during consolidation; gains and losses stemming from these translations are included as a component of Other Comprehensive Income and reported within Accumulated Comprehensive Income within our Consolidated Balance Sheets. Income and expenses of our international subsidiaries are translated at average exchange rates for the period and, when included within retained earnings in the balance sheet at current exchange rates, the differences to those average exchange rates are included within Other Comprehensive Income and reported within Accumulated Comprehensive Income. When our subsidiaries transact business in currencies other than their functional currency, those transactions are revalued in their functional currency and differences resulting from such revaluations are included within other non-operating income (deduction), net within our Consolidated Statement of Income.
We do not anticipate that near-term changes in exchange rates will have a material impact on our future earnings or cash flows. However, there can be no assurance that a sudden and significant change in the value of foreign currencies would not have a material adverse effect on our financial condition and results of operations.
Interest Rate Sensitivity
A portion of our long-term bank debt bears interest at variable rates (see Note 15 to the Consolidated Financial Statements) and our results of operations would be affected by interest rate changes to such bank debt outstanding. The Company utilizes interest rate swaps to limit exposure to market fluctuations on floating-rate debt. In the second quarter of 2023, the Company entered into a floating to fixed interest rate swap for a notional amount of $150 million. The fair value of this instrument as of December 31, 2024 is an asset of $0.3 million. An immediate 10% increase in the interest rates would not have a material effect on our results of operations over the next fiscal year. A one percentage point change in interest rates would cost $4.3 million in incremental interest charges on an annual basis.
Credit Risk
We are exposed to credit risk on certain assets, primarily accounts receivable. We provide credit to customers in the ordinary course of business and perform ongoing credit evaluations. Concentrations of credit risk with respect to trade receivables are limited due to the large number of customers comprising our customer base. We currently believe our allowance for doubtful accounts is sufficient to cover customer credit risks. Our accounts receivable financial instruments are carried at amounts that approximate fair value.
In addition, in 2024, our credit exposure included an unfunded loan commitment in connection with the DIP Credit Agreement. As a result, the Company recorded a provision for credit loss of $30 million in the second quarter of 2024 (see Note 17 to the Consolidated Financial Statements).
Sovereign Debt Risk
We do not have any material credit risk with sovereign governments as we do not sell our products to them. We do, however, sell to customers in these countries, but we believe our risk associated with these customers is not material.

MINERALS TECHNOLOGIES INC. AND SUBSIDIARY COMPANIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Note 1. Summary of Significant Accounting Policies
Business
Minerals Technologies Inc. (the “Company”) is a leading, technology-driven specialty minerals company that develops, produces, and markets a broad range of mineral and mineral-based products, related systems and services. The Company serves globally a wide range of consumer and industrial markets, including household and personal care, paper and packaging, food and pharmaceutical, automotive, construction, steel and foundry, environmental, and infrastructure.
Basis of Presentation
The accompanying consolidated financial statements include the accounts of the Company, its wholly and majority-owned subsidiaries, as well as variable interest entities for which the Company is the primary beneficiary. All intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates
The Company employs accounting policies that are in accordance with U.S. generally accepted accounting principles and require management to make estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reported period. Significant estimates include those related to valuation of long-lived assets, goodwill and other intangible assets, certain pension plan assumptions, valuation of deferred income tax assets, and litigation and environmental liabilities. Actual results could differ from those estimates.
Cash Equivalents and Short-term Investments
The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents. Short-term investments consist of financial instruments, mainly bank deposits, with original maturities beyond three months, but less than twelve months. Short-term investments amounted to $4.0 million and $4.3 million at December 31, 2024 and 2023, respectively. There were no unrealized holding gains or losses on the short-term bank investments held at December 31, 2024.
Trade Accounts Receivable
Trade accounts receivables are recorded at the invoiced amount and do not bear interest. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in the Company’s existing accounts receivable. The Company determines the allowance based on historical write-off experience and specific allowances for bankrupt customers. The Company also analyzes the collection history and financial condition of its other customers, considering current industry conditions and determines whether an allowance needs to be established. The Company reviews its allowance for doubtful accounts monthly. Past due balances over 90 days based on payment terms are reviewed individually for collectability. Allowance for doubtful accounts was $17.1 million and $20.3 million at December 31, 2024 and 2023, respectively. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. The Company does not have any off-balance-sheet credit exposure related to its customers.
Allowance for Credit Losses
The allowance for credit losses (ACL) is management's estimate of the current expected credit losses at the balance sheet date. Our credit exposure includes an unfunded loan commitment. For this exposure, we recognized an ACL associated with the unfunded amount, which is reported as a liability in accrued expenses and other current liabilities on our consolidated balance sheet.
Inventories
Inventories are valued at the lower of cost or market. Cost is determined by the first-in, first-out (FIFO) method.
Additionally, items such as idle facility expense, freight handling costs, and re-handling costs are recognized as current period charges. The allocation of fixed production overheads to the costs of conversion are based upon the normal capacity of the production facility. Fixed overhead costs associated with idle capacity are expensed as incurred.
F-7

MINERALS TECHNOLOGIES INC. AND SUBSIDIARY COMPANIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Property, Plant and Equipment
Property, plant and equipment are recorded at cost. Significant improvements are capitalized, while maintenance and repair expenditures are charged to operations as incurred. The Company capitalizes interest cost as a component of construction in progress. The straight-line method of depreciation is used for substantially all the assets for financial reporting purposes, except for mining related equipment which uses units-of-production method. The annual rates of depreciation are 3% - 6.67% for buildings, 6.67% - 12.5% for machinery and equipment, 8% - 12.5% for furniture and fixtures and 12.5% - 25% for computer equipment and software-related assets. The estimated useful lives of our PCC production facilities and machinery and equipment pertaining to our natural stone mining and processing plants and our chemical plants are 15 years.
Property, plant and equipment are depreciated over their useful lives. Useful lives are based on management’s estimates of the period that the assets can generate revenue, which does not necessarily coincide with the remaining term of a customer’s contractual obligation to purchase products made using those assets. The Company’s sales of PCC are predominantly pursuant to long-term evergreen contracts, initially ten years in length, with paper mills at which the Company operates satellite PCC plants. The terms of many of these agreements have been extended, often in connection with an expansion of the satellite PCC plant. Failure of a PCC customer to renew an agreement or continue to purchase PCC from a Company facility could result in an impairment of assets charge or accelerated depreciation at such facility.
Depletion of mineral reserves is determined on a unit-of-extraction basis for financial reporting purposes, based upon proven and probable reserves, and generally on a percentage depletion basis for tax purposes.
Stripping Costs Incurred During Production
Stripping costs are those costs incurred for the removal of waste materials for the purpose of accessing ore body that will be produced commercially. Stripping costs incurred during the production phase of a mine are variable costs that are included in the costs of inventory produced during the period that the stripping costs are incurred.
Accounting for the Impairment of Long-Lived Assets
Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable, the Company estimates the undiscounted future cash flows (excluding interest), resulting from the use of the asset and its ultimate disposition. If the sum of the undiscounted cash flows (excluding interest) is less than the carrying value, the Company recognizes an impairment loss, measured as the amount by which the carrying value exceeds the fair value of the asset, determined principally using discounted cash flows.
Goodwill and Other Intangible Assets
Goodwill represents the excess of purchase price and related costs over the value assigned to the net tangible and identifiable intangible assets of businesses acquired. Goodwill is not amortized, but instead assessed for impairment. Intangible assets with estimable useful lives are amortized on a straight-line basis over their respective estimated lives to the estimated residual values and reviewed for impairment.
The Company performs a qualitative assessment for each of its reporting units to determine if the two-step process for impairment testing is required. If the Company determines that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the Company would then evaluate the recoverability of goodwill using a two-step impairment test approach at the reporting unit level. In the first step, the fair value for the reporting unit is compared to its book value including goodwill. In the case that the fair value of the reporting unit is less than book value, a second step is performed which compares the fair value of the reporting unit’s goodwill to the book value of the goodwill. The fair value for the goodwill is determined based on the difference between the fair values of the reporting unit and the net fair values of the identifiable assets and liabilities of such reporting unit. If the fair value of the goodwill is less than the book value, the difference is recognized as impairment.
In addition to the assessment of goodwill impairment, the Company also reviews its other identifiable intangibles for impairment. Each year, the Company reviews whether events or changes in circumstances could indicate that a long-lived asset’s carrying amount may not be recoverable. Should such events occur, the value of intangibles not recoverable would be recognized as impairment.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Investment in Joint Ventures
The Company uses the equity method of accounting to record the results of its investments in companies in which it has significant influence but does not control; and cost method of accounting in companies in which it cannot exercise significant control. The Company records the equity in earnings of its investments in joint ventures on a one-month lag. At December 31, 2024 and 2023, the book value of the Company’s equity method investments was $23.4 million and $20.0 million.
Accounting for Asset Retirement Obligations
The Company provides for obligations associated with the retirement of long-lived assets and the associated asset retirement costs. The fair value of a liability for an asset retirement obligation is recognized in the period in which it is incurred if a reasonable estimate of fair value can be made. The associated asset retirement costs are capitalized as part of the carrying amount of the long-lived asset. The Company also provides for legal obligations to perform asset retirement activities where timing or methods of settlement are conditional on future events.
The Company also records liabilities related to land reclamation as a part of the asset retirement obligations. The Company mines land for various minerals using a surface-mining process that requires the removal of overburden. In many instances, the Company is obligated to restore the land upon completion of the mining activity. As the overburden is removed, the Company recognizes this liability for land reclamation based on the estimated fair value of the obligation. The obligation is adjusted to reflect the passage of time and changes in estimated future cash outflows.
Fair Value of Financial Instruments
The recorded amounts of cash and cash equivalents, receivables, short-term borrowings, accounts payable, accrued interest, and variable-rate long-term debt approximate fair value because of the short maturity of those instruments or the variable nature of underlying interest rates. Short-term investments are recorded at cost, which approximates fair market value.
Derivative Financial Instruments
The Company records derivative financial instruments which are used to hedge certain foreign exchange risk at fair value on the balance sheet. See Note 12 for a full description of the Company’s hedging activities and related accounting policies.
Revenue Recognition
Revenue is recognized at the point in time when the customer obtains control of the promised goods or services in an amount that reflects the consideration we expect to receive in exchange for those goods or services. The Company’s revenues are primarily derived from the sale of products. Our primary performance obligation is satisfied upon shipment or delivery to our customer based on written sales terms, which is also when control is transferred. Revenues from sales of equipment are recorded upon completion of installation and transfer of control to the customer. Revenue where our performance obligations are satisfied in phases is recognized over time using certain input measures based on the measurement of the value transferred to the customer, including milestones achieved. Revenues from services are recorded when the services are performed.
In most of our PCC contracts, the price per ton is based upon the total number of tons sold to the customer during the year. Under those contracts, the price billed to the customer for shipments during the year is based on periodic estimates of the total annual volume that will be sold to the customer. Revenues are adjusted at the end of each year to reflect the actual volume sold. There were no significant revenue adjustments in the fourth quarter of 2024 and 2023, respectively. We have consignment arrangements with certain customers in our Engineered Solutions segment. Revenues for these transactions are recorded when the consigned products are consumed by the customer.
Foreign Currency
The assets and liabilities of the Company’s international subsidiaries are translated into U.S. dollars using exchange rates at the respective balance sheet date. The resulting translation adjustments are recorded in accumulated other comprehensive income (loss) in shareholders’ equity. Income statement items are generally translated at monthly average exchange rates prevailing during the period. International subsidiaries operating in highly inflationary economies translate non-monetary assets at historical rates, while net monetary assets are translated at current rates, with the resulting translation adjustments included in net income. At December 31, 2024, the Company had no international subsidiaries operating in highly inflationary economies, with the exception of its subsidiaries in Turkey.

MINERALS TECHNOLOGIES INC. AND SUBSIDIARY COMPANIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Income Taxes
Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.
The Company operates in multiple taxing jurisdictions, both within the U.S. and outside the U.S. In certain situations, a taxing authority may challenge positions that the Company has adopted in its income tax filings. The Company regularly assesses its tax position for such transactions and includes reserves for those differences in position. The reserves are utilized or reversed once the statute of limitations has expired or the matter is otherwise resolved.
The application of income tax law is inherently complex. Laws and regulations in this area are voluminous and are often ambiguous. As such, we are required to make many subjective assumptions and judgments regarding our income tax exposures. Interpretations of and guidance surrounding income tax laws and regulations change over time. As such, changes in our subjective assumptions and judgments can materially affect amounts recognized in the consolidated balance sheets and statements of operations. The Company’s accounting policy is to recognize interest and penalties as part of its provision for income taxes. See Note 8 for additional details on our uncertain tax positions.
The accompanying financial statements do not include a provision for foreign withholding taxes on international subsidiaries’ unremitted earnings, which are expected to be permanently reinvested overseas.
Research and Development
Research and development costs are expensed as incurred.
Accounting for Stock-Based Compensation
The Company recognizes compensation expense for share-based awards based upon the grant date fair value over the vesting period.
Pension and Post-retirement Benefits
The Company has defined benefit pension plans covering the majority of its eligible employees. The benefits are generally based on years of service and an employee’s modified career earnings.
The Company also provides post-retirement healthcare benefits for the majority of its retirees and employees in the United States. The Company measures the costs of its obligation based on its best estimate. The net periodic costs are recognized as employees render the services necessary to earn the post-retirement benefits.
Environmental
Expenditures that relate to current operations are expensed or capitalized as appropriate. Expenditures that relate to an existing condition caused by past operations and which do not contribute to current or future revenue generation are expensed. Liabilities are recorded when it is probable the Company will be obligated to pay amounts for environmental site evaluation, remediation or related costs, and such amounts can be reasonably estimated.
Earnings Per Share
Basic earnings per share have been computed based upon the weighted average number of common shares outstanding during the period.
Diluted earnings per share have been computed based upon the weighted average number of common shares outstanding during the period assuming the issuance of common shares for all potentially dilutive common shares outstanding.

Subsequent Events
The Company has evaluated for subsequent events through the date of issuance of its financial statements.
Recently Issued Accounting Standards
Changes to accounting principles generally accepted in the United States of America (U.S. GAAP) are established by the Financial Accounting Standards Board (FASB) in the form of accounting standards updates (ASUs) to the FASB’s Accounting Standards Codification. The Company considers the applicability and impact of all ASUs. ASUs not listed below were assessed and determined to be either not applicable or are expected to have minimal impact on our consolidated financial position and results of operations.
Adoption of Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures
In November 2023, the FASB issued ASU 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures”, which requires entities to report incremental information about significant segment expenses included in a segment’s profit or loss measure, as well as the name and title of the chief operating decision maker. The guidance also requires interim disclosures related to reportable segment profit or loss and assets that had previously only been disclosed annually. The new standard is effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2023. The Company adopted this guidance on January 1, 2024 and updated the disclosures contained in Note 21. This guidance did not impact the Company's consolidated financial statements.
Income Taxes (Topic 740): Improvements to Income Tax Disclosures
In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures”, that requires entities to disclose additional information about federal, state, and foreign income taxes primarily related to the income tax rate reconciliation and income taxes paid. The new standard also eliminates certain existing disclosure requirements related to uncertain tax positions and unrecognized deferred tax liabilities. The new standard is effective for interim and annual periods beginning on or after December 15, 2024. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements, but will result in disaggregation of the Company's tax footnote.
Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses
In November 2024, the FASB issued ASU 2024-03, “Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses”, that requires entities to disclose additional information in the notes to the financial statements about prescribed categories underlying any relevant income statement expense caption. The new standard is effective for annual periods beginning after December 15, 2026 and interim periods within fiscal years beginning after December 15, 2027. The adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements.
Note 2. Leases
The Company determines if an arrangement is a lease at inception. The Company has operating leases for premises, equipment, rail cars and automobiles. Our leases have remaining lease terms of 1 year to 50 years, some of which may include options to extend the leases further. The Company considers these options in determining the lease term used to establish the right-of-use assets and lease liabilities. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based upon the information available at commencement date, or as of implementation of ASC 842, in determining the present value of lease payments.
Leases with an initial term of 12 months or less are not recorded on the balance sheet. We recognize lease expense for these leases on a straight-line basis over the lease term. Certain lease agreements contain both lease and non-lease components. We account for lease components together with non-lease components.

Note 3. Revenue from Contracts with Customers
The Company's revenues are primarily derived from the sale of products in product lines within our Consumer & Specialties and Engineered Solutions businesses.
Our primary performance obligation (the sale of products) is satisfied upon shipment or delivery to our customers based on written sales terms, which is also when control is transferred. In most of our contracts in our Specialty Additives product line, which is in our Consumer & Specialties segment, the price per ton is based upon the total number of tons sold to the customer during the year. Under these contracts, the price billed to the customer for shipments during the year is based on periodic estimates of the total annual volume that will be sold to such customer. Revenues are adjusted at the end of each year to reflect the actual volume sold.
Revenue from sales of equipment, primarily in our High-Temperature Technologies product line within our Engineered Solutions segment, is recorded upon completion of installation and control is transferred to the customer. Revenue from services is recorded when the services have been performed. Included within our High-Temperature Technologies product line are certain consignment arrangements with certain customers in our Engineered Solutions segment. Revenues for these transactions are recorded when the consigned products are consumed by the customer and control is transferred.
Revenue where our performance obligations are satisfied in phases is recognized over time using certain input measures based on the measurement of the value transferred to the customer, including milestones achieved.
The following table disaggregates our revenue by major source (product line) for the years ended December 31, 2024, 2023 and 2022:

Note 4. Acquisitions
Concept Pet Heimtierprodukte GmbH
On April 29, 2022, the Company completed the acquisition of Concept Pet Heimtierprodukte GmbH (“Concept Pet”), a European supplier of pet litter products. The purchase of Concept Pet supports the expansion of our European pet care business, as well as providing additional mineral reserves. The purchase price was $28.0 million and the acquisition was financed through cash on hand. The fair value of the total consideration transferred, net of cash acquired, was $22.4 million. In the second quarter of 2023, an additional $1.8 million of hold back consideration was paid. In the second quarter of 2024, an additional $4.0 million was paid representing the final hold back consideration. The results of Concept Pet are included within our Household & Personal Care product line in our Consumer & Specialties segment. The acquisition has been accounted for using the acquisition method of accounting, which requires, among other things, that we recognize the assets acquired and liabilities assumed at their respective fair values as of the acquisition date. The Company recorded goodwill of $9.3 million and intangible assets of $4.3 million relating to this acquisition.
The Company incurred no acquisition related transaction and integration costs during 2024 and recorded $0.3 million and $5.1 million of acquisition-related costs during 2023 and 2022, respectively, which are reflected within the acquisition-related expenses line of the Consolidated Statements of Income.

Note 5. Restructuring and Other Items, net
In the third quarter of 2023, the Company recorded a $71.7 million non-cash impairment of long-lived assets charge related to its subsidiaries BMI Oldco Inc. (f/k/a Barretts Minerals Inc.) ("Oldco") and Barretts Ventures Texas LLC ("BVT") within the Consumer & Specialties segment. This impairment was triggered by increased claims and continued increases in legal costs, which led to the voluntary filing for relief under Chapter 11 of the U.S. Bankruptcy Code to address and comprehensively resolve Oldco’s liabilities associated with the talc claims. See Note 17 for further information.
In the second quarter of 2023, the Company initiated a restructuring and cost savings program to further streamline our cost structure as a result of organizational efficiencies gained through our 2023 resegmentation. As a result, the Company recorded a charge of $6.6 million for restructuring and other charges related to severance and other costs. In the third quarter of 2023, an incremental charge of $0.3 million was recorded relating to this program.

Note 6. Stock-Based Compensation
The Company’s 2015 Stock Award and Incentive Plan provides for grants of incentive and non-qualified stock options, restricted stock, restricted stock units, stock appreciation rights, stock awards and performance unit awards (the 2015 Stock Award and Incentive Plan, as amended, referred to herein as the “Plan” and together with its predecessor for awards granted prior to May 2015, the 2001 Stock Award and Incentive Plan, as amended and restated, the “Plans”). At the Company's 2024 Annual Meeting of Stockholders, the Company's stockholders ratified the adoption of an amendment and restatement of the Plan, which increased the number of shares available for issuance pursuant to the Plan by 889,000 shares and removed certain individual award limits in light of recent tax law changes. The Plans are administered by the Compensation Committee of the Board of Directors. Stock options granted under the Plans generally have a ten year term. The exercise price for stock options are at prices at or above the fair market value of the common stock on the date of the grant, and each award of stock options will vest ratably over a specified period, generally three years.

The related tax benefit included in the statement of income on the non-qualified stock options was $1.4 million, $1.4 million and $1.3 million for 2024, 2023 and 2022, respectively.
Stock Options
The fair value of options granted is estimated on the date of grant using the Black-Scholes valuation model. Compensation expense is recognized only for those options expected to vest, with forfeitures estimated at the date of grant based on the Company’s historical experience and future expectations. The forfeiture rate assumption used for the periods ended December 31, 2024, 2023 and 2022 was 7.69%, 7.91% and 8.09%, respectively.
The weighted average grant date fair value for stock options granted during the years ended December 31, 2024, 2023 and 2022 was $25.33, $25.11 and $24.26, respectively. The weighted average grant date fair value for stock options vested during 2024, 2023 and 2022 was $23.75, $21.56 and $19.82, respectively. The total intrinsic value of stock options exercised during the years ended December 31, 2024, 2023 and 2022 was $7.0 million, $1.0 million and $2.0 million, respectively.
The fair value for stock awards was estimated at the date of grant using the Black-Scholes option valuation model with the following weighted average assumptions for the years ended December 31, 2024, 2023 and 2022:

|  | Year Ended December 31, |
|  | 2024 |  |  | 2023 |  |  | 2022 |
Expected life (in years) |  |  | 6.5 |  |  |  | 6.4 |  |  |  | 6.7 |
Interest rate |  |  | 4.06 | % |  |  | 3.51 | % |  |  | 1.70 | %
Volatility |  |  | 31.93 | % |  |  | 32.05 | % |  |  | 31.92 | %
Expected dividend yield |  |  | 0.61 | % |  |  | 0.30 | % |  |  | 0.28 | %

The expected term of the options represents the estimated period of time until exercised and is based on historical experience of similar awards, based upon contractual terms, vesting schedules, and expectations of future employee behavior. The expected stock-price volatility is based upon the historical and implied volatility of the Company’s stock. The interest rate is based upon the implied yield on U.S. Treasury bills with an equivalent remaining term. Estimated dividend yield is based upon historical dividends paid by the Company.

The Company has $23.2 million of deferred tax assets arising from tax loss carry forwards which will be realized through future operations. Carry forwards of approximately $14.2 million expire over the next 20 years, and $9.0 million can be utilized over an indefinite period.
On December 31, 2024, the Company had $1.9 million of total unrecognized tax benefits. Included in this amount were a total of $1.3 million of unrecognized income tax benefits that, if recognized, would affect the Company’s effective tax rate. While it is expected that the amount of unrecognized tax benefits will change in the next 12 months, we do not expect the change to have a significant impact on the results of operations or the financial position of the Company.
The following table summarizes the activity related to our unrecognized tax benefits:

(millions of dollars) |  | 2024 |  |  | 2023 |
Balance at beginning of the year |  | $ | 2.8 |  |  | $ | 2.6 |

Balance at the end of the year |  | $ | 1.9 |  |  | $ | 2.8 |

The Company’s accounting policy is to recognize interest and penalties accrued, relating to unrecognized income tax benefits as part of its provision for income taxes. The Company recorded a net reversal of $0.1 million in interest and penalties during 2024 and had a total accrued balance on December 31, 2024 of $0.4 million. The Company believes that its accrued liabilities are sufficient to cover its U.S. and foreign tax contingencies.
The Company operates in multiple taxing jurisdictions, both within and outside the U.S. In certain situations, a taxing authority may challenge positions that the Company has adopted in its income tax filings. The Company, with a few exceptions (none of which are material), is no longer subject to U.S. federal, state, local, and international income tax examinations by tax authorities for years prior to 2017.

The Company had approximately $497.7 million of foreign subsidiaries’ undistributed earnings as of December 31, 2024. We intend to continue to permanently reinvest these earnings overseas for the foreseeable future and while U.S. federal tax expense has been recognized as a result of recent U.S. tax code changes, no deferred tax liabilities with respect to foreign withholding taxes or state taxes have been recognized.
In December 2021, the Organization for Economic Co-operation and Development (“OECD”) released the Pillar Two Model Rules which aim to reform international corporate taxation rules, including the implementation of a global minimum tax rate.

Note 11. Goodwill and Other Intangible Assets
Goodwill and other intangible assets with indefinite lives are not amortized, but instead are assessed for impairment, at least annually. The carrying amount of goodwill was $913.8 million and $913.6 million as of December 31, 2024 and December 31, 2023, respectively. The net change in goodwill since December 31, 2024 was attributable to the effects of foreign exchange.
The balance of goodwill by reporting unit and the activity occurring in the past two fiscal years is as follows:

Note 12. Derivative Financial Instruments and Hedging Activities
As a multinational corporation with operations throughout the world, the Company is exposed to certain market risks. The Company uses a variety of practices to manage these market risks, including, when considered appropriate, derivative financial instruments. The Company’s objective is to offset gains and losses resulting from interest rates and foreign currency exposures with gains and losses on the derivative contracts used to hedge them. The Company uses derivative financial instruments only for risk management and not for trading or speculative purposes.
By using derivative financial instruments to hedge exposures to changes in interest rates and foreign currencies, the Company exposes itself to credit risk and market risk. Credit risk is the risk that the counterparty will fail to perform under the terms of the derivative contract. When the fair value of a derivative contract is positive, the counterparty owes the Company, which creates credit risk for the Company. When the fair value of a derivative contract is negative, the Company owes the counterparty, and therefore, it does not face any credit risk. The Company minimizes the credit risk in derivative instruments by entering into transactions with major financial institutions.

MINERALS TECHNOLOGIES INC. AND SUBSIDIARY COMPANIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Market risk is the adverse effect on the value of a financial instrument that results from a change in interest rates, currency exchange rates, or commodity prices. The market risk associated with interest rate and forward exchange contracts is managed by establishing and monitoring parameters that limit the types and degree of market risk that may be undertaken.
Cash Flow Hedges
For derivative instruments that are designated and qualify as cash flow hedges, the Company records the effective portion of the gain or loss in accumulated other comprehensive income (loss) as a separate component of shareholders’ equity. The Company subsequently reclassifies the effective portion of gain or loss into earnings in the period during which the hedged transaction is recognized in earnings.
The Company utilizes interest rate swaps to limit exposure to market fluctuations on floating-rate debt. In the second quarter of 2023, the Company entered into a floating to fixed interest rate swap for a notional amount of $150 million. The fair value of this swap is an asset of $0.3 million at December 31, 2024 and is recorded in other assets and deferred charges on the Consolidated Balance Sheet. This interest rate swap is designated as a cash flow hedge. As a result, the gains and losses associated with this interest rate swap are recorded in accumulated other comprehensive income (loss).
Other
The Company is exposed to potential gains or losses from foreign currency fluctuations affecting net investments and earnings denominated in foreign currencies. The Company is particularly sensitive to currency exchange rate fluctuations for the following currencies: British pound sterling (GBP), Chinese renminbi (CNY), Euro, Malaysian ringgit (MYR), Polish zloty (PLN), South African Rand (ZAR), Thai baht (THB) and Turkish lira (TRY). When considered appropriate, the Company enters into foreign exchange derivative contracts to mitigate the risk of fluctuations on these exposures. The Company does not designate these contracts for hedge accounting treatment and the changes in fair value of these contracts are recorded in earnings. The Company recorded losses of $0.1 million, $0.1 million and $0.8 million in other non-operating income (deductions), net within the Consolidated Statements of Income for the years ended 2024, 2023 and 2022 respectively. There were no open contracts at December 31, 2024 and December 31, 2023.
Note 13. Fair Value of Financial Instruments
Fair value is an exchange price that would be received for an asset or paid to transfer a liability (exit price) in an orderly transaction between market participants at the measurement date. The Company utilizes market data or assumptions that market participants would use in pricing the asset or liability. The Company follows a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs about which little or no market data exists, therefore requiring an entity to develop its own assumptions.
Assets and liabilities measured at fair value are based on one or more of three valuation techniques. The three valuation techniques are as follows:

| ● | Market approach – prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities.

| ● | Cost approach – amount that would be required to replace the service capacity of an asset or replacement cost.

| ● | Income approach – techniques to convert future amounts to a single present amount based on market expectations, including present value techniques, option-pricing and other models.

The Company primarily applies the income approach for foreign exchange derivatives for recurring fair value measurements and attempts to utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
The following table sets forth by level within the fair value hierarchy the Company’s financial assets and liabilities accounted for at fair value on a recurring basis at the end of each of the past two years. Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of fair value assets and liabilities and their placement within the fair value hierarchy levels.

The fair value of foreign exchange contracts is determined based on inputs that are readily available in public markets or can be derived from information available in publicly quoted markets and are categorized as Level 2. Deferred compensation and supplementary pension plan assets related to the Company’s 2014 acquisition of AMCOL International Corporation are valued using quoted prices for similar assets in active markets.
The Company does not have any financial assets or liabilities measured at fair value on a recurring basis categorized as Level 3, except for pension assets discussed in Note 16, and there were no transfers in or out of Level 3 during the year ended December 31, 2024 and 2023. There were also no changes to the Company’s valuation techniques used to measure asset and liability fair values on a recurring basis.
Note 14. Financial Instruments and Concentrations of Credit Risk
The following methods and assumptions were used to estimate the fair value of each class of financial instrument:
Cash and cash equivalents, short-term investments, accounts receivable and payable: The carrying amounts approximate fair value because of the short maturities of these instruments.
Short-term debt and other liabilities: The carrying amounts of short-term debt and other liabilities approximate fair value because of the short maturities of these instruments.
Long-term debt: The fair value of the long-term debt of the Company is estimated based on the quoted market prices for that debt or similar debt and approximates the carrying amount.
F-22

MINERALS TECHNOLOGIES INC. AND SUBSIDIARY COMPANIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Forward exchange contracts: The fair value of forward exchange contracts (used for hedging purposes) is based on information derived from active markets. If appropriate, the Company would enter into forward exchange contracts to mitigate the impact of foreign exchange rate movements on the Company’s operating results. It does not engage in speculation. Such foreign exchange contracts would offset losses and gains on the assets, liabilities and transactions being hedged.
Credit risk: The Company provides credit to customers in the ordinary course of business. The Company’s customer base is diverse and includes customers located throughout the world. Credit risk results from the possibility that a loss may occur from the failure of another party to perform according to the terms of the contracts. The Company regularly monitors its credit risk exposures and takes steps to mitigate the likelihood of these exposures resulting in an actual loss. In the second quarter of 2024, the Company entered into a Debtor-in-Possession Credit Agreement with Oldco and recorded a provision for credit losses of $30.0 million for the maximum principal amount under such Credit Agreement. See Note 17 for further information. The Company’s extension of credit is based on an evaluation of the customer’s financial condition and collateral is generally not required.
The Company’s bad debt expense for the years ended December 31, 2024, 2023 and 2022 was $1.4 million, $2.8 million and $4.1 million, respectively.

On November 26, 2024, the Company, entered into a Refinancing Facility Agreement and Incremental Facility Amendment (the “Amendment”) to amend the previous credit agreement (the "Previous Credit Agreement"; the previous credit agreement, as amended by the Amendment, being the "Amended Credit Agreement").
The Amendment provides for, among other things, a new senior secured revolving credit facility with aggregate commitments of $400 million (the “Revolving Facility”), a portion of which may be used for the issuance of letters of credit and swingline loans, and a new senior secured term loan facility with aggregate commitments of $575 million (the “Term Loan Facility” and, together with the Revolving Facility, the "Senior Secured Credit Facilities"). The Revolving Facility and the Term Loan Facility replace the facilities under the Previous Credit Agreement, which provided for, among other things, a $550 million senior secured term loan facility and a $300 million senior secured revolving credit facility. The maturity date for loans and commitments under the Revolving Facility is November 26, 2029, and the maturity date for loans under the Term Loan Facility is November 26, 2031; provided that the maturity dates of the Revolving Facility and the Term Loan Facility will be adjusted to the date that is 91 days prior to the stated maturity date of the Company’s 5.0% Senior Notes due 2028 (the “Notes”) unless, prior to the date that is 91 days prior to the stated maturity date of the Notes, all amounts in excess of $50 million of the Notes have been either (a) refinanced with indebtedness permitted under the Amended Credit Agreement maturing later than 90 days after the scheduled maturity date of the Revolving Facility or of the Term Loan Facility, as applicable, or (b) repaid, discharged or repaid (other than with the proceeds of any indebtedness maturing earlier than 91 days after the scheduled maturity date of the Revolving Facility or of the Term Loan Facility, as applicable). Loans under the Term Loan Facility amortize at a rate equal to 1.00% per annum, payable in equal quarterly installments, and were issued with original issue discount at 99.875% of par.

On June 30, 2020, the Company issued $400 million aggregate principal amount of “Notes”. The Notes were issued pursuant to an indenture, dated as of June 30, 2020, between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Indenture”). The Notes bear an interest rate of 5.0% per annum payable semi-annually on January 1 and July 1 of each year, beginning on January 1, 2021. The Notes are unconditionally guaranteed on a senior unsecured basis by each of the Company’s existing and future wholly owned domestic restricted subsidiaries that is a borrower under or that guarantees the Company’s obligations under its Senior Secured Credit Facilities or that guarantees the Company’s or any of the Company’s wholly owned domestic subsidiaries’ long-term indebtedness in an aggregate amount in excess of $50 million.
The Company may redeem some or all of the Notes at any time and from time to time at the applicable redemption prices listed in the Indenture, plus accrued and unpaid interest, if any, to, but excluding, the applicable redemption date.
If the Company experiences a change of control (as defined in the indenture), the Company is required to offer to repurchase the Notes at 101% of the principal amount of such Notes, plus accrued and unpaid interest, if any, to, but excluding, the date of repurchase.
The Amended Credit Agreement and the Indenture both contain certain customary affirmative and negative covenants that limit or restrict the ability of the Company and its restricted subsidiaries to enter into certain transactions or take certain actions, as well as customary events of default. In addition, the Amended Credit Agreement contains a financial covenant that requires the Company to maintain a maximum Net Leverage Ratio of 4.00 to 1.00 for each four fiscal quarter period (subject to an increase to 5.00 to 1.00 for four quarters in connection with certain significant acquisitions).
The Company has a committed loan facility in Japan. As of December 31, 2024, there was an outstanding balance of $0.9 million on this facility. Principal will be repaid in accordance with the payment schedule ending in 2026. The Company repaid $0.4 million on this loan in 2024.

Note 16. Benefit Plans
Pension Plans and Other Postretirement Benefit Plans
The Company and its subsidiaries have pension plans covering the majority of eligible employees on a contributory or non-contributory basis. Benefits under defined benefit plans are generally based on years of service and an employee’s career earnings. Employees generally become fully vested after five years.
The Company also provides postretirement health care and life insurance benefits for the majority of its U.S. retired employees. Employees are generally eligible for benefits upon retirement and completion of a specified number of years of creditable service. The Company does not pre-fund these benefits and has the right to modify or terminate the plan in the future.
The Company’s disclosures for the U.S. plans have been combined with those outside of the U.S. as the international plans do not have significantly different assumptions, and together represent approximately 20% of our total benefit obligation.
The following table sets forth the Company’s pension obligation and funded status at December 31:

The Company’s funding policy for U.S. plans generally is to contribute annually into trust funds at a rate that provides for future plan benefits and maintains appropriate funded percentages. Annual contributions to the U.S. qualified plans are at least sufficient to satisfy regulatory funding standards and are not more than the maximum amount deductible for income tax purposes. The funding policies for the international plans conform to local governmental and tax requirements. The plans’ assets are invested primarily in stocks and bonds.

The weighted average assumptions used to determine benefit obligations for the pension benefit plans and other benefit plans at December 31, 2024, 2023 and 2022 are as follows:

| Year Ended December 31, |
| 2024 |  | 2023 |  | 2022 |

For 2024, 2023 and 2022, the discount rate was based on the FTSE Pension Discount Curve, a yield curve of high quality corporate bonds with cash flows matching our plans’ expected benefit payments. The expected return on plan assets is based on our asset allocation mix and our historical return, taking into account current and expected market conditions. The actual return/(loss) on pension assets was approximately 10% in 2024, 11% in 2023 and (22)% in 2022.
The Company maintains a self-funded health insurance plan for its retirees. This plan provided that the maximum health care cost trend rate would be 5%. Effective June 2010, the Company amended its plan to change the eligibility requirement for retirees and revised its plan so that increases in expected health care costs would be borne by the retiree. Effective January 1, 2022, the plan was closed to new retirees.

Investment Strategies
The investment strategy for pension plan assets is to maintain a broadly diversified portfolio designed to both preserve and grow plan assets to meet future plan obligations. The Company’s average rate of return on assets from inception through December 31, 2024 was approximately 9%. The Company’s assets are strategically allocated among equity, debt and other investments to achieve a diversification level that dampens fluctuations in investment returns. The Company’s long-term investment strategy is an investment portfolio mix of approximately 55%-65% in equity securities, 30%-35% in fixed income securities and 0%-15% in other securities.
Savings and Investment Plan
The Company maintains a voluntary Savings and Investment Plan (a 401(k) plan) for most non-union employees in the U.S. Within prescribed limits, the Company bases its contribution to the Savings and Investment Plan on employee contributions. The Company’s contributions amounted to $6.4 million, $6.2 million and $5.7 million for the years ended December 31, 2024, 2023 and 2022, respectively.
Note 17. Contingencies
The Company is party to a number of lawsuits arising in the normal course of our business. The Company and certain of the Company’s subsidiaries are among numerous defendants in a number of cases seeking damages for alleged exposure to asbestos-contaminated talc products sold by the Company’s subsidiary BMI Oldco Inc.
On October 2, 2023 (the “Petition Date”), notwithstanding the Company’s confidence in the safety of Oldco’s talc products, the Company’s subsidiaries, Oldco and Barretts Ventures Texas LLC ("BVT" and, together with Oldco, the “Chapter 11 Debtors”), filed voluntary petitions for relief under Chapter 11 of the U.S. Bankruptcy Code in the United States Bankruptcy Court for the Southern District of Texas (the “Chapter 11 Cases”) to address and comprehensively resolve Oldco’s liabilities associated with talc. Minerals Technologies Inc. and the Company’s other subsidiaries were not included in the Chapter 11 filing.
The Chapter 11 Debtors’ ultimate goal in the Chapter 11 Cases is to confirm a plan of reorganization under Section 524(g) of the U.S. Bankruptcy Code and utilize this provision of the Bankruptcy Code to establish a trust that will address all current and future talc-related claims. In January 2024, the Chapter 11 Debtors and Minerals Technologies Inc. commenced a court-approved mediation process with the Official Committee of Unsecured Creditors (appointed in the Chapter 11 Cases as the representative of current talc claimants) (the “Committee”) and the Future Claimants Representative (appointed in the Chapter 11 Cases as the representative of future talc claimants) regarding the terms of a potential consensual plan of reorganization and the ultimate amount to be contributed to any trust. The mediation process is ongoing.

As of December 31, 2024, we had 684 open cases related to certain talc products previously sold by Oldco, which is an increase in volume from previous years. The following table details case activity related to talc products previously sold by Oldco:

During the pendency of the Chapter 11 Cases, the Company anticipates that the Chapter 11 Debtors will benefit from the operation of the automatic stay, which stays ongoing litigation in connection with talc-related claims against the Chapter 11 Debtors. In addition, subject to certain exceptions, the filing or continued prosecution of all talc-related claims against the Chapter 11 Debtors’ non-debtor affiliates is temporarily stayed through April 15, 2025 (subject to further extensions), the date on which a hearing is scheduled on the status of the Chapter 11 Cases.
These claims typically allege various theories of liability, including negligence, gross negligence and strict liability and seek compensatory and, in some cases, punitive damages, but most of these claims do not provide adequate information to assess their merits, the likelihood that the Company will be found liable, or the magnitude of such liability, if any. We are unable to state an amount or range of amounts claimed in any of these lawsuits because state court pleading practices do not require the plaintiff to identify the amount of the claimed damage. The Company’s position, as stated publicly, is that the talc products sold by Oldco are safe and do not cause cancer.
The Company records accruals for loss contingencies associated with legal matters, including talc-related litigation, when it is probable that a liability will be incurred and the amount of the loss can be reasonably estimated. Amounts accrued for legal contingencies often result from a complex series of judgments about future events and uncertainties that rely heavily on estimates and assumptions including timing of related payments. The ability to make such estimates and judgments can be affected by various factors, including whether damages sought in the proceedings are unsubstantiated or indeterminate, the stage of the litigation, the factual and legal matters in dispute, the ability to achieve comprehensive settlements, the availability of co-defendants with substantial resources and assets participating in the litigation, and our evaluation of the unique attributes of each claim.
While costs relating to the talc-related cases have increased concurrently with the volume, the majority of these costs have historically been borne by Pfizer Inc. ("Pfizer") in connection with certain agreements entered into in connection with the Company’s initial public offering in 1992, and as long as the litigation is subject to the stay under the Chapter 11 Cases (subject to certain exceptions), the Company will not be required to make any payments in respect thereof. The Company is entitled to indemnification, pursuant to agreement, for liabilities arising from sales prior to the initial public offering. On May 22, 2024, Pfizer filed a motion in the Chapter 11 Cases seeking permission to file a lawsuit against the Company related to the 1992 agreement. That motion has been adjourned, and Pfizer and the Company have agreed to mediate their disputes. The Company continues to receive information from Pfizer with respect to potential costs associated with the defense and/or settlement of talc-related cases that Pfizer alleges are not subject to indemnification. Although the Company believes that the talc products are safe and that claims to the contrary are without merit, Oldco opportunistically settled certain talc-related cases in 2022 and 2023. None of such settlements have been material to the Company.
In the second quarter of 2024, Oldco sold its talc assets under section 363 of the Bankruptcy Code. In addition, in the second quarter of 2024, the Company entered into a Debtor-in-Possession Credit Agreement with Oldco (the “DIP Credit Agreement”) and recorded a provision for credit loss of $30 million for the maximum principal amount under such Credit Agreement.
F-31

MINERALS TECHNOLOGIES INC. AND SUBSIDIARY COMPANIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Proceeds of the sale of Oldco’s talc assets and funds drawn by Oldco under the DIP Credit Agreement will be used to fund the Chapter 11 Cases. Following the Chapter 11 filing, the activities of the Chapter 11 Debtors are now subject to review and oversight by the bankruptcy court. As a result, the Chapter 11 Debtors were deconsolidated as of the Petition Date, and their assets and liabilities were derecognized from the Company’s consolidated financial statements on a prospective basis.
On June 25, 2024, the Committee filed a motion to dismiss the Chapter 11 Cases. A hearing on the motion to dismiss, which has been adjourned several times while the parties continue to explore a consensual resolution of issues through the court-approved mediation process, is scheduled to commence on April 14, 2025 (subject to further adjournments). The Chapter 11 Cases remain pending.
The broader litigation and regulatory environments for talc-related claims continue to evolve. Moreover, although the Chapter 11 Cases are progressing, it is not possible at this time to predict how the Bankruptcy Court will rule on the pending motion to dismiss, the form of any ultimate resolution, or when an ultimate resolution might occur. Given the foregoing factors, it is reasonably possible that the Company will incur a loss for liabilities associated with future talc claims in excess of the amount currently recognized. This risk is based on the potential for new talc-related claims that could eventually be asserted together with their associated disposition cost and related legal costs, despite the automatic stay with respect to claims against the Chapter 11 Debtors, taking into account the portion of such hypothetical claims that may be subject to indemnification by Pfizer, as well as the inability to estimate the amount that may be necessary to fully and finally resolve all of the Chapter 11 Debtors’ future talc-related claims in connection with a confirmed Chapter 11 plan of reorganization. Accordingly, the Company is currently unable to provide an estimate or range of the magnitude of any potential loss related to future talc claims. While possible losses associated with future talc claims are not reasonably estimable at this time based on our current knowledge, in light of the uncertainties involved in such matters, the resolution of, or recognition of additional liabilities in connection with, current or future talc claims could have a material adverse effect on the Company’s results of operations, cash flows and financial condition.

Note 20. Accounting for Asset Retirement Obligations
The Company records asset retirement obligations in which the Company will be required to retire tangible long-lived assets. These are primarily related to its PCC satellite facilities and mining operations. The Company has also recorded the provisions related to conditional asset retirement obligations at its facilities. The Company has recorded asset retirement obligations at all of its facilities except where there are no contractual or legal obligations. The associated asset retirement costs are capitalized as part of the carrying amount of the long-lived asset.
The following is a reconciliation of asset retirement obligations as of December 31, 2024 and 2023:

|  | December 31, |
(millions of dollars) |  | 2024 |  |  | 2023 |

Note 21. Segment and Related Information
The Company determines its operating segments based on the discrete financial information that is regularly evaluated by its chief operating decision maker, our Chief Executive Officer, in deciding how to allocate resources and in assessing performance. The Company’s operating segments are strategic business units that offer different products and serve different markets. They are managed separately and require different technology and marketing strategies.
The Company has two reportable segments: the Consumer & Specialties segment and the Engineered Solutions segment.
The Consumer & Specialties segment serves consumer end markets directly and provides mineral-based solutions and technologies that are essential to our customers’ products. The two product lines in this segment are Household & Personal Care - our mineral-to-shelf product line that serves pet care, personal and household care, fluid purification and other consumer oriented markets, and Specialty Additives, delivering specialty mineral additives to a variety of consumer and industrial end markets including paper, packaging, construction, automotive, and food and pharmaceuticals.
The Engineered Solutions segment combines all engineered systems, mineral blends, and technologies that are designed to aid in customer processes and projects. The two product lines in this segment are High-Temperature Technologies – combining all of our mineral-based blends, technologies, and systems serving the foundry, steel, glass, aluminum and other high-temperature processing industries, and Environmental & Infrastructure, which includes environmental and remediation solutions such as geosynthetic clay lining systems, water remediation technologies as well as drilling, commercial building and infrastructure-related products.
The accounting policies of the segments are the same as those described in the summary of significant accounting policies. The Company evaluates performance based on the operating income of the respective business units. The costs deducted to arrive at operating profit do not include several items, such as net interest or income tax expense. Depreciation expense related to corporate assets is allocated to the business segments and is included in their income from operations. However, such corporate depreciable assets are not included in the segment assets. Intersegment sales and transfers are not significant.
Segment revenues, expenses, operating income and a reconciliation of the operating segment totals to the applicable line items on the consolidated financial statements is as follows:

Report of Independent Registered Public Accounting Firm
To the Shareholders and Board of Directors
Minerals Technologies Inc.:
Opinion on the Consolidated Financial Statements
We have audited the accompanying consolidated balance sheets of Minerals Technologies Inc. and subsidiaries (the Company) as of December 31, 2024 and December 31, 2023, the related consolidated statements of income, comprehensive income, cash flows, and changes in shareholders’ equity for each of the years in the three-year period ended December 31, 2024, and the related notes and financial statement schedule (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and December 31, 2023, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2024, in conformity with U.S. generally accepted accounting principles.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 21, 2025 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.
Basis for Opinion
These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated 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 consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matters
The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.
Evaluation of talc litigation liability
As discussed in Note 17 to the consolidated financial statements, the Company and certain of the Company’s subsidiaries are among numerous defendants in a number of cases seeking damages for alleged exposure to asbestos-contaminated talc products sold by the Company’s subsidiary BMI Oldco Inc. (Oldco). On October 2, 2023, the Company’s subsidiaries, Oldco and Barretts Ventures Texas LLC, filed voluntary petitions for relief under Chapter 11 of the U.S. Bankruptcy Code in the United States Bankruptcy Court for the Southern District of Texas (the “Chapter 11 Cases”) to address and comprehensively resolve Oldco’s liabilities associated with talc.
We identified the evaluation of the talc litigation liability as a critical audit matter. A high degree of complex auditor judgment was required to evaluate the Company’s talc litigation liability due to the nature of the estimate and key assumptions, including the assessment of the likelihood of a loss being incurred and whether a reasonable estimate of the loss or range of loss for the future and existing talc claims could be made.
F-38

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls related to the Company’s talc litigation liability estimation process. This included controls over determining the key assumptions noted above and claims data utilized in the process. We evaluated the reasonableness of the Company’s talc litigation liability estimate by:

| ● | evaluating the professional qualifications, knowledge, skills, and ability of the Company’s external specialist used in compiling and evaluating claims data

| ● | assessing the talc related legal cases settled during the year and the open cases as of December 31, 2024, by evaluating letters obtained directly from the Company’s external and internal legal counsel

| ● | testing a selection of claims data used in the Company’s talc accrual calculation by comparing the selected items to underlying claims documentation

| ● | discussing the status and processing of significant known, actual, and potential litigation, and the status of ongoing Oldco bankruptcy proceedings with the Company’s in-house legal counsel, as well as external counsel

| ● | evaluating management’s assessment regarding whether an unfavorable outcome is reasonably possible or probable and reasonably estimable.

Measurement of projected pension benefit obligations
As discussed in Note 16 to the consolidated financial statements, the Company’s projected pension benefit obligations were $342.3 million as of December 31, 2024. The Company estimates the liability related to their pension plans using actuarial models that include assumptions about the Company's discount rates.
We identified the measurement of the Company’s projected pension benefit obligations as a critical audit matter. Specialized skills are required to evaluate the Company’s assumptions. In particular, especially complex auditor judgement was required to assess the discount rates used in the determination of projected pension benefit obligations.
The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls over the Company’s pension process, including a control related to the Company’s assessment of the discount rates utilized within the actuarial models. We obtained an understanding of the actuarial models used by the Company in selecting the discount rate for each plan and inquired as to whether there have been changes to this methodology in the current year. We also involved an actuarial professional with specialized skills and knowledge, who assisted in evaluating the Company’s analysis of the discount rates and assessed the discount rates considering the timing and amount of benefit payments used in the determination of the projected pension benefit obligation.

Report of Independent Registered Public Accounting Firm
To the Shareholders and Board of Directors
Minerals Technologies Inc.:
Opinion on Internal Control Over Financial Reporting
We have audited Minerals Technologies Inc. and subsidiaries’ (the Company) internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2024 and 2023, the related consolidated statements of income, comprehensive income, cash flows, and changes in shareholders’ equity for each of the years in the three-year period ended December 31, 2024, and the related notes and financial statement schedule (collectively, the consolidated financial statements), and our report dated February 21, 2025 expressed an unqualified opinion on those consolidated financial statements.
Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report On Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control Over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management’s Report On Internal Control Over Financial Reporting
Management of Minerals Technologies Inc. is responsible for the preparation, integrity and fair presentation of its published consolidated financial statements. The financial statements have been prepared in accordance with U.S. generally accepted accounting principles and, as such, include amounts based on judgments and estimates made by management. The Company also prepared the other information included in the annual report and is responsible for its accuracy and consistency with the consolidated financial statements.
Management is also responsible for establishing and maintaining effective internal control over financial reporting. The Company’s internal control over financial reporting includes those policies and procedures that pertain to the Company’s ability to record, process, summarize and report reliable financial data. The Company maintains a system of internal control over financial reporting, which is designed to provide reasonable assurance to the Company’s management and board of directors regarding the preparation of reliable published financial statements and safeguarding of the Company’s assets. The system includes a documented organizational structure and division of responsibility, established policies and procedures, including a code of conduct to foster a strong ethical climate, which are communicated throughout the Company, and the careful selection, training and development of our people.
The Board of Directors, acting through its Audit Committee, is responsible for the oversight of the Company’s accounting policies, financial reporting and internal control. The Audit Committee of the Board of Directors is comprised entirely of outside directors who are independent of management. The Audit Committee is responsible for the appointment and compensation of the independent registered public accounting firm. It meets periodically with management, the independent registered public accounting firm and the internal auditors to ensure that they are carrying out their responsibilities. The Audit Committee is also responsible for performing an oversight role by reviewing and monitoring the financial, accounting and auditing procedures of the Company in addition to reviewing the Company’s financial reports. The independent registered public accounting firm and the internal auditors have full and unlimited access to the Audit Committee, with or without management, to discuss the adequacy of internal control over financial reporting, and any other matters which they believe should be brought to the attention of the Audit Committee.
Management recognizes that there are inherent limitations in the effectiveness of any system of internal control over financial reporting, including the possibility of human error and the circumvention or overriding of internal control. Accordingly, even effective internal control over financial reporting can provide only reasonable assurance with respect to financial statement preparation and may not prevent or detect misstatements. Further, because of changes in conditions, the effectiveness of internal control over financial reporting may vary over time.
The Company assessed its internal control system as of December 31, 2024 in relation to criteria for effective internal control over financial reporting described in “Internal Control – Integrated Framework (2013)” issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on its assessment, the Company has determined that, as of December 31, 2024, its system of internal control over financial reporting was effective.
The consolidated financial statements have been audited by the independent registered public accounting firm, which was given unrestricted access to all financial records and related data, including minutes of all meetings of stockholders, the Board of Directors and committees of the Board. Reports of the independent registered public accounting firm, which includes the independent registered public accounting firm’s attestation of the effectiveness of the Company’s internal control over financial reporting are also presented within this document.
