Note 1. Basis of Presentation and Summary of Significant Accounting Policies
The accompanying unaudited condensed consolidated financial statements have been prepared by management of Minerals Technologies Inc. (the “Company”, “MTI”, “we”, or “us”) in accordance with the rules and regulations of the United States Securities and Exchange Commission. Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles have been condensed or omitted. Therefore, these financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023. In the opinion of management, all adjustments, consisting solely of normal recurring adjustments necessary for a fair presentation of the financial information for the periods indicated, have been included. The results for the three-month periods ended March 31, 2024 are not necessarily indicative of the results that may be expected for the year ending December 31, 2024.
Company Operations
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, food and pharmaceutical, paper, packaging, automotive, construction, and environmental.
The Company has two reportable segments: Consumer & Specialties and Engineered Solutions.

– | 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.

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 revenue recognition, valuation of long-lived assets, goodwill and other intangible assets, income taxes, including valuation allowances, contingent liabilities, and pension plan assumptions. Actual results could differ from those estimates.
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.

Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures
In November 2023, the FASB issued ASU 2024-07, “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 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 financial statements.
Income Taxes (Topic 740): Improvements to Income Tax Disclosures
In December 2023, the FASB issued ASU 2024-09, “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 financial statements.

Of the options outstanding of 1,671,687 and 1,608,613 for the three-month periods ended March 31, 2024 and April 2, 2023, respectively, options to purchase 900,163 shares and 1,002,344 shares of common stock for the three-month periods ending March 31, 2024 and April 2, 2023, respectively, were not included in the computation of diluted earnings per share because they were anti-dilutive, as the exercise prices of the options were greater than the average market price of the common shares.
Note 4. Restructuring and Other Items, net
In the second quarter of 2023, the Company initiated a restructuring and cost savings program to further streamline its cost structure as a result of organizational efficiencies gained through the resegmentation in the first quarter of 2023. 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.
At March 31, 2024, the Company had $3.7 million included within other current liabilities in the Condensed Consolidated Balance Sheet for cash expenditures needed to satisfy remaining obligations under workforce reduction initiatives. The Company expects to pay these amounts by end of 2024.
The following table is a reconciliation of our restructuring liability balance as of March 31, 2024:

(in millions of dollars) |  |  |
Restructuring liability, December 31, 2023 |  | $ | 3.8 |
Cash payments |  |  | (0.1 | )
Restructuring liability, March 31, 2024 |  | $ | 3.7 |

Note 5. Income Taxes
Provision for taxes was $13.9 million and $10.5 million during the three-month periods ended March 31, 2024 and April 2, 2023, respectively. The effective tax rate was 23.1% for the three months ended March 31, 2024, as compared with 22.0% for the three months ended April 2, 2023. The higher tax rate was primarily due to the mix of earnings.
As of March 31, 2024, the Company had approximately $2.9 million of total unrecognized income tax benefits. Included in this amount were a total of $2.1 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, the Company does not expect the change to have a significant impact on the results of operations or the financial position of the Company.
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 had a net addition of approximately $0.1 million during the three-month period ended March 31, 2024 and had an accrued balance of $0.6 million of interest and penalties as of March 31, 2024.
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.
In December 2021, as part of the Organization for Economic Co-operation and Development’s (“OECD”) released the Pillar Two Model Rules which aim to reform international corporate taxation rules, including the implementation of a global minimum tax rate. The Company began implementation of the Pillar Two Model Rules in the first quarter of 2024. The Company continues to assess the rules in all jurisdictions and does not anticipate a material impact to its financial statements.

Note 7. 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 $913.1 million and $913.6 million as of March 31, 2024 and December 31, 2023, respectively. The net change in goodwill from December 31, 2023 to March 31, 2024 is attributable to the effects of foreign exchange.
Acquired intangible assets subject to amortization as of March 31, 2024 and December 31, 2023 were as follows:

|  |  |  |  | Mar. 31, 2024 |  |  | Dec. 31, 2023 |
(in millions of dollars) |  | Weighted Average Useful Life (Years) |  |  | Gross Carrying Amount |  |  | Accumulated Amortization |  |  | Gross Carrying Amount |  |  | Accumulated Amortization |

|  |  | 29 |  |  | $ | 324.9 |  |  | $ | 97.3 |  |  | $ | 325.7 |  |  | $ | 94.7 |

The weighted average amortization period for acquired intangible assets subject to amortization is approximately 29 years. Estimated amortization expense is $8.8 million for the remainder of 2024, $47.8 million for 2025–2028 and $171.0 million thereafter.
Note 8. Derivative Financial Instruments
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.
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 $1.9 million at March 31, 2024 and is recorded in other assets and deferred charges on the Condensed 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).
Assets and liabilities measured at fair value are based on one or more of three valuation techniques. The three valuation techniques are as follows:

On August 11, 2022, the Company entered into a Refinancing Facility Agreement (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 $300 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 $550 million (the “Term Loan Facility” and, together with the Revolving Facility, the “Senior Secured Credit Facilities”). The Revolving Facility and the Term Loan Facility replaced the facilities under the Previous Credit Agreement, which provided for, among other things, a $788 million senior secured floating rate term loan facility and a $300 million senior secured revolving credit facility. The maturity date for loans under the Senior Secured Credit Facilities is August 11, 2027.

Loans under the Senior Secured Credit Facilities will bear interest at a rate equal to, at the election of the Company, Term SOFR plus a credit spread adjustment equal to 0.100% plus an applicable margin equal to 1.500% per annum or a base rate plus an applicable margin equal to 0.500% per annum, subject in each case to (a) an increase of 25 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, (b) a decrease of 12.5 basis points in the event that, and for so long as, the net leverage ratio is less than 2.00 to 1.00 and greater than or equal to 1.00 to 1.00 as of the last day of the preceding fiscal quarter and (c) an decrease of 25 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. The Company will pay certain fees under the Amended Credit Agreement, including (a) a commitment fee of 0.250% per annum on the undrawn portion of the Revolving Facility (subject to a step-up to 0.300% and step-downs to 0.175% and 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 third quarter of 2023, the Company's subsidiaries Barretts Minerals Inc. and Barretts Ventures Texas LLC were removed as borrowers under, and Guarantors of, the Senior Secured Credit Facilities.
As of March 31, 2024, there were $75.0 million in loans and $9.1 million in letters of credit outstanding under the Revolving Facility.
On June 30, 2020, the Company issued $400 million aggregate principal amount of 5.0% Senior Notes due 2028 (the “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. In the third quarter of 2023, the Company’s subsidiaries Barretts Minerals Inc. and Barretts Ventures Texas LLC were removed as guarantors of the Notes.
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 financial covenants that require the Company to maintain, as of the last day of any fiscal quarter, (x) a maximum net leverage ratio (as defined in the Amended Credit Agreement) of 4.00 to 1.00 for the four fiscal quarter period preceding such day (subject to an increase to 5.00 to 1.00 for four quarters in connection with certain significant acquisitions) and (y) a minimum interest coverage ratio (as defined in the Amended Credit Agreement) of 3.00 to 1.00. The Company is in compliance with all the covenants contained in the Amended Credit Agreement throughout the period covered by this report.
The Company has a committed loan facility in Japan. As of March 31, 2024, $1.2 million was outstanding under this loan facility. Principal will be repaid in accordance with the payment schedule ending in 2026. The Company repaid $0.1 million on this facility in the first quarter of 2024.
As part of the acquisition of Concept Pet Heimtierprodukte GmbH ("Concept Pet") in 2022, 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 did not make repayments on these loans during the first quarter of 2024.
As of March 31, 2024, the Company had $25.3 million in uncommitted short-term bank credit lines, of which $0.7 million were in use.

Note 10. Benefit Plans
The Company and its subsidiaries have pension plans covering the majority of eligible employees on a contributory or non-contributory basis. The Company also provides postretirement health care and life insurance benefits for the majority of its U.S. retired employees. 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 less than 21% of our total benefit obligation.

Note 12. 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 Barretts Minerals Inc. (“BMI”). On October 2, 2023 (the “Petition Date”), notwithstanding the Company’s confidence in the safety of BMI’s talc products, the Company’s subsidiaries, BMI and Barretts Ventures Texas LLC (together with BMI, “Barretts”), 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 BMI’s liabilities associated with talc. Minerals Technologies Inc. and the Company’s other subsidiaries were not included in the Chapter 11 filing. During the pendency of the Chapter 11 Cases, the Company anticipates that BMI will benefit from the operation of the automatic stay, which stays ongoing litigation in connection with talc-related claims against BMI. In addition, subject to certain exceptions, the filing or continued prosecution of all talc-related claims against BMI’s non-debtor affiliates is temporarily stayed through May 13, 2024 (subject to further extensions), the date on which a hearing is scheduled on the status of the Chapter 11 Cases.
As of March 31, 2024, we had 594 open cases related to certain talc products previously sold by BMI, which is an increase from previous years. As a result of the Chapter 11 Cases, these cases are stayed. The following table details case activity related to talc products previously sold by BMI:

|  | Three Months Ended |
(number of claims) |  | Mar. 31, 2024 |  |  | Apr. 2, 2023 |
Claims pending, beginning of period |  |  | 574 |  |  |  | 439 |
Claims filed |  |  | 30 |  |  |  | 62 |
Claims dismissed, settled or otherwise resolved |  |  | 10 |  |  |  | 41 |
Claims pending, end of period |  |  | 594 |  |  |  | 460 |

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 BMI 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. 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, 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. The Company continues to receive information from Pfizer Inc. 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, BMI opportunistically settled certain talc-related cases in 2022 and 2023. None of such settlements have been material to the Company.
In the first quarter of 2024, BMI entered into an agreement to sell its talc assets under section 363 of the Bankruptcy Code. The sale is expected to close in the second quarter of 2024. Proceeds of the sale will be used to fund the Chapter 11 Cases. BMI’s 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 to establish a trust that will address all current and future talc-related claims. Following the Chapter 11 filing, the activities of Barretts are now subject to review and oversight by the bankruptcy court. As a result, Barretts was deconsolidated as of the Petition Date, and its assets and liabilities were derecognized from the Company’s consolidated financial statements on a prospective basis.
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 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 BMI, taking into account the portion of such hypothetical claims that may be subject to indemnification by Pfizer Inc., as well as the inability to estimate the amount that may be necessary to fully and finally resolve all of BMI’s 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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Shareholders and Board of Directors
Minerals Technologies Inc.:
Results of Review of Interim Financial Information
We have reviewed the condensed consolidated balance sheet of Minerals Technologies Inc. and subsidiaries (the Company) as of March 31, 2024, the related condensed consolidated statements of income, comprehensive income, changes in shareholders' equity, and cash flows for the three-month periods ended March 31, 2024 and April 2, 2023, and the related notes (collectively, the consolidated interim financial information). Based on our reviews, we are not aware of any material modifications that should be made to the consolidated interim financial information for it to be in conformity with U.S. generally accepted accounting principles.
We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheet of the Company as of December 31, 2023, and the related consolidated statements of income, comprehensive income, changes in shareholders’ equity, and cash flows for the year then ended (not presented herein); and in our report dated February 16, 2024, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidated balance sheet as of December 31, 2023 is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.
Basis for Review Results
This consolidated interim financial information is the responsibility of the Company’s management. 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 reviews in accordance with the standards of the PCAOB. A review of consolidated interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the PCAOB, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Segment Review
The following discussions highlight the operating results for each of our two segments.

|  | Three Months Ended |  |  |  |
Consumer & Specialties Segment |  | Mar. 31, 2024 |  |  | Apr. 2, 2023 |  |  | % Change |
|  | (in millions of dollars) |  |  |  |
Net Sales |  |  |  |  |  |  |  |  |
Household & Personal Care |  | $ | 138.4 |  |  | $ | 129.2 |  |  |  | 7 | %
Special Additives |  |  | 158.5 |  |  |  | 168.1 |  |  |  | (6 | )%
Total net sales |  | $ | 296.9 |  |  | $ | 297.3 |  |  |  | 0 | %
Income from operations |  | $ | 42.0 |  |  | $ | 32.2 |  |  |  | 30 | %
% of net sales |  |  | 14.1 | % |  |  | 10.8 | % |  |  |  |

Net sales in the Consumer & Specialties segment was $296.9 million for the three months ended March 31, 2024, as compared with $297.3 million in the prior year. Household & Personal Care sales increased 7% to $138.4 million, as compared with $129.2 million in the prior year on continued strong demand for our pet litter products as well as growth in other high-margin consumer-oriented products. Sales in Specialty Additives decreased $9.6 million, or 6% as compared with prior year. Included in sales from the prior year were $13.1 million of sales related to BMI, which was deconsolidated in the fourth quarter of 2023.
Income from operations was $42.0 million and represented 14.1% of sales, as compared to $32.2 million in the prior year and 10.8% of sales, a 30% improvement. This increase was the result of volume growth, productivity improvement, pricing and cost control.

|  | Three Months Ended |  |  |  |
Engineered Solutions Segment |  | Mar. 31, 2024 |  |  | Apr. 2, 2023 |  |  | % Change |
|  | (in millions of dollars) |  |  |  |
Net Sales |  |  |  |  |  |  |  |  |
High-Temperature Technologies |  | $ | 177.3 |  |  | $ | 178.6 |  |  |  | (1 | )%
Environmental & Infrastructure |  |  | 60.3 |  |  |  | 70.2 |  |  |  | (14 | )%

% of net sales |  |  | 16.2 | % |  |  | 14.2 | % |  |  |  |

Net sales in the Engineered Solutions segment decreased 5% to $237.6 million from $248.8 million in the prior year primarily driven by slow commercial construction market conditions in North America. High-Temperature Technologies sales decreased 1% to $177.3 million, as compared with $178.6 in the prior year. Environmental & Infrastructure sales decreased 14% to $60.3 million, as compared with $70.2 million in the prior year due to slow commercial construction market conditions and two large remediation projects that were completed in the first quarter of 2023.
Income from operations was $38.5 million and 16.2% of sales as compared with $35.3 million and 14.2% of sales in the prior year driven by strong operating performance in High-Temperature Technologies.
Liquidity and Capital Resources
Cash provided from operations during the three months ended March 31, 2024, was approximately $55.9 million. Cash flows provided from operations during the first three months of 2024 were principally used to fund capital expenditures, repay debt, repurchase shares, and to pay the Company’s dividend to common shareholders. The aggregate maturities of long-term debt are as follows: remainder of 2024 - $14.4 million; 2025 - $31.7 million; 2026 - $41.9 million; 2027 - $443.7 million; 2028 - $400.0 million; thereafter - $0.0 million.

On August 11, 2022, the Company entered into a Refinancing Facility Agreement (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 $300 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 $550 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 $788 million senior secured floating rate term loan facility and a $300 million senior secured revolving credit facility. The maturity date for loans under the Senior Secured Credit Facilities is August 11, 2027.
Loans under the Senior Secured Credit Facilities will bear interest at a rate equal to, at the election of the Company, Term SOFR plus a credit spread adjustment equal to 0.100% plus an applicable margin equal to 1.500% per annum or a base rate plus an applicable margin equal to 0.500% per annum, subject in each case to (a) an increase of 25 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, (b) a decrease of 12.5 basis points in the event that, and for so long as, the net leverage ratio is less than 2.00 to 1.00 and greater than or equal to 1.00 to 1.00 as of the last day of the preceding fiscal quarter and (c) an decrease of 25 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. The Company will pay certain fees under the Amended Credit Agreement, including (a) a commitment fee of 0.250% per annum on the undrawn portion of the Revolving Facility (subject to a step-up to 0.300% and step-downs to 0.175% and 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 third quarter of 2023, the Company’s subsidiaries Barretts Minerals Inc. and Barretts Ventures Texas LLC were removed as borrowers under, and Guarantors of, the Senior Secured Credit Facilities.
As of March 31, 2024, there were $75.0 million in loans and $9.1 million in letters of credit outstanding under the Revolving Facility.
On June 30, 2020, the Company issued $400 million aggregate principal amount of 5.0% Senior Notes due 2028 (the “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. In the third quarter of 2023, the Company’s subsidiaries Barretts Minerals Inc. and Barretts Ventures Texas LLC were removed as guarantors of the Notes.
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 financial covenants that require the Company to maintain, as of the last day of any fiscal quarter, (x) a maximum net leverage ratio (as defined in the Amended Credit Agreement) of 4.00 to 1.00 for the four fiscal quarter period preceding such day (subject to an increase to 5.00 to 1.00 for four quarters in connection with certain significant acquisitions) and (y) a minimum interest coverage ratio (as defined in the Amended Credit Agreement) of 3.00 to 1.00. The Company is in compliance with all the covenants contained in the Amended Credit Agreement throughout the period covered by this report.
The Company has a committed loan facility in Japan. As of March 31, 2024, $1.2 million was outstanding under this loan facility. Principal will be repaid in accordance with the payment schedule ending in 2026. The Company repaid $0.1 million on this facility during 2024.
23

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 did not make repayments on these loans during the first quarter of 2024.
As of March 31, 2024, the Company had $25.3 million in uncommitted short-term bank credit lines, of which $0.7 million 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 2024 should be between $90 million and $100 million, principally related to opportunities to improve our operations and meet our strategic growth objectives.
In the second quarter of 2023, the Company entered into a new floating to fixed interest rate swap for a notional amount of $150 million. The fair value of this instrument at March 31, 2024 is an asset of $1.9 million.
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. As of March 31, 2024, 443,775 shares have been repurchased under this program for $29.2 million, or an average price of approximately $65.76 per share.
The Company is required to make future payments under various contracts, including debt agreements and lease agreements. The Company also has commitments to fund its pension plans and provide payments for other postretirement benefit plans. During the three months ended March 31, 2024, there were no material changes in the Company’s contractual obligations.
The Company and certain of the Company’s subsidiaries are among numerous defendants in over five hundred cases seeking damages for alleged exposure to asbestos-contaminated talc products sold by the Company’s subsidiary BMI. The Company’s position is that these cases are meritless and all talc products sold by BMI are safe. On October 2, 2023 (the “Petition Date”), notwithstanding the Company’s confidence in the safety of BMI’s talc products, Barretts, 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 BMI’s liabilities associated with talc. Minerals Technologies Inc. and the Company’s other subsidiaries were not included in the Chapter 11 filing. In the first quarter of 2024, BMI entered into an agreement to sell its talc assets under section 363 of the U.S. Bankruptcy Code. The sale is expected to close in the second quarter of 2024. Proceeds of the sale will be used to fund the Chapter 11 Cases. Barretts’ 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 to establish a trust that will address all current and future talc-related claims. During the pendency of the Chapter 11 Cases, the Company anticipates that BMI will benefit from the operation of the automatic stay, which stays ongoing litigation in connection with talc-related claims against Barretts. In addition, subject to certain exceptions, the filing or continued prosecution of all talc-related claims against Barretts’ non-debtor affiliates is temporarily stayed through May 13, 2024 (subject to further extensions), the date on which a hearing is scheduled on the status of the Chapter 11 Cases. Barretts has 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 BMI’s 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 12 to the condensed consolidated financial statements included in this report for more information.
Cautionary Statement for “Safe Harbor” Purposes under the Private Securities Litigation Reform Act of 1995
The Private Securities Litigation Reform Act of 1995 provides a safe harbor for forward-looking statements made by or on behalf of the Company. This report contains statements that the Company believes may be “forward-looking statements” within the meaning of Section 21E of the Securities Exchange Act of 1934, particularly statements relating to the Company’s objectives, plans or goals, future actions, future performance or results of current and anticipated products, sales efforts, expenditures, and financial results. From time to time, the Company also provides forward-looking statements in other publicly-released materials, both written and oral. Forward-looking statements provide current expectations and forecasts of future events such as new products, revenues and financial performance, and are not limited to describing historical or current facts. They can be identified by the use of words such as “outlook,” “forecast,” “believes,” “expects,” “plans,” “intends,” “anticipates,” and other words and phrases of similar meaning.
24

Forward-looking statements are necessarily based on assumptions, estimates and limited information available at the time they are made. A broad variety of risks and uncertainties, both known and unknown, as well as the inaccuracy of assumptions and estimates, can affect the realization of the expectations or forecasts in these statements. Many of these risks and uncertainties are difficult to predict or are beyond the Company’s control. Consequently, no forward-looking statement can be guaranteed. Actual future results may vary materially. Significant factors that could affect the expectations and forecasts include worldwide general economic, business, and industry conditions; the cyclicality of our customers’ businesses and their changing regional demands; our ability to compete in very competitive industries; consolidation in customer industries, principally paper, foundry and steel; our ability to renew or extend long term sales contracts for our satellite operations; our ability to generate cash to service our debt; our ability to comply with the covenants in the agreements governing our debt; our ability to effectively achieve and implement our growth initiatives or consummate the transactions described in the statements; our ability to successfully develop new products; our ability to defend our intellectual property; the increased risks of doing business abroad; the availability of raw materials and access to ore reserves at our mining operations, or increases in costs of raw materials, energy, or shipping; compliance with or changes to regulation in the areas of environmental, health and safety, and tax; risks and uncertainties related to the voluntary petitions for relief under Chapter 11 of the U.S. Bankruptcy Code filed by our subsidiaries Barretts Minerals Inc. and Barretts Ventures Texas LLC; claims for legal, environmental and tax matters or product stewardship issues; operating risks and capacity limitations affecting our production facilities; seasonality of some of our businesses; cybersecurity and other threats relating to our information technology systems; and other risk factors set forth under “Item 1A — Risk Factors” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, and in Exhibit 99 to this Quarterly Report on Form 10-Q.
The Company undertakes no obligation to update any forward-looking statements to reflect events or circumstances that arise after the date hereof. Investors should refer to the Company’s subsequent filings under the Securities Exchange Act of 1934 for further disclosures.
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.
Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures
In November 2023, the FASB issued ASU 2024-07, “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 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 financial statements.
Income Taxes (Topic 740): Improvements to Income Tax Disclosures
In December 2023, the FASB issued ASU 2024-09, “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 financial statements.
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.
There have been no material changes to the critical accounting estimates that our accounting policies require us to make in the preparation of our consolidated financial statements, as described in the 2023 Annual Report on Form 10-K.

ITEM 3. Quantitative and Qualitative Disclosures about Market Risk
Market risk represents the risk of loss that may impact our financial position, results of operations or cash flows due to adverse changes in market prices and foreign currency and interest rates. We are exposed to market risk because of changes in foreign currency exchange rates as measured against the U.S. dollar. 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 decline in the value of foreign currencies would not have a material adverse effect on our financial condition and results of operations. A portion of our long-term bank debt bears interest at variable rates; therefore, our results of operations would be affected by interest rate changes to the extent of such outstanding bank debt. An immediate 10 percent change in interest rates would have a material effect on our results of operations over the next fiscal year. A one-percent change in interest rates, inclusive of the impact of our interest rate derivatives, would result in $3.8 million in incremental interest charges on an annual basis.
We do not enter into derivatives or other financial instruments for trading or speculative purposes. When appropriate, we enter into derivative financial instruments, such as forward exchange contracts, hedges and interest rate swaps, to mitigate the impact of foreign exchange rate movements and interest rate movements on our operating results. The counterparties are major financial institutions. Such forward exchange contracts, hedges and interest rate swaps would not subject us to additional risk from exchange rate or interest rate movements because gains and losses on these contracts would offset losses and gains on the assets, liabilities, and transactions being hedged.
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 at March 31, 2024 is an asset of $1.9 million.
ITEM 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
As of the end of the period covered by this report, and under the supervision and with participation of the Company’s management, including the Chief Executive Officer and the Chief Financial Officer, the Company carried out an evaluation of the effectiveness of the design and operation of the Company’s disclosure controls and procedures, pursuant to Exchange Act Rule 13a-15(b). Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that as of the end of the period covered by this report the Company’s disclosure controls and procedures were effective.
Changes in Internal Control Over Financial Reporting
There were no changes in the Company’s internal controls over financial reporting during the quarter ended March 31, 2024 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
