Key Terms

asset retirement obligation, commodity derivatives, cash flow hedge, Secured Overnight Financing Rate, +2 more

6 terms

asset retirement obligation financial

"The activity included in other liabilities for years 2025 and 2024 is as follows (in thousands)"

A liability recorded for the future cost to retire, dismantle or clean up a long-lived asset — for example removing an oil rig, closing a mine, or decommissioning a plant. Investors care because it reduces reported profit and ties up capital: companies must estimate and set aside money now for a known future expense, and changes to that estimate can swing earnings, debt ratios and the company’s cash needs much like setting aside savings to repair or return a rented property later.

commodity derivatives financial

"the Company’s financial instruments measured at fair value include commodity derivatives, interest rate swaps"

Commodity derivatives are financial contracts whose value is tied to the price of a physical raw material—such as oil, gold, wheat or copper—and they let parties lock in or bet on future prices without necessarily owning the actual goods. For investors, they matter because they offer ways to protect profits from wild price swings (like locking the price of fuel ahead of a trip) or to gain exposure and potential returns through leverage, but they also carry higher risk and require close attention to market supply, demand and storage factors.

cash flow hedge financial

"These instruments are being accounted for as cash flow hedges and mature in November 2026"

A cash flow hedge is an accounting label for a contract or arrangement used to offset expected future swings in a company’s cash payments or receipts — for example from variable-rate interest, foreign currency sales, or forecasted purchases. It matters to investors because it aims to smooth future cash and earnings volatility: gains or losses on the hedge are held out of current profit and reported separately until the underlying transaction affects results, much like buying insurance to steady future bills.

Secured Overnight Financing Rate financial

"receives payments equal to the Secured Overnight Financing Rate"

A secured overnight financing rate (SOFR) is a daily benchmark interest rate that reflects the cost of borrowing cash overnight using U.S. Treasury securities as collateral. Think of it as the market price to “rent” cash for a day with a very safe pledge, similar to paying a short-term rental fee for money backed by government bonds. Investors track SOFR because it underpins pricing for loans, bonds and derivatives, so movements change borrowing costs, interest income and the valuation of interest-rate–linked positions.

accumulated other comprehensive income financial

"Accumulated other comprehensive income — net of related tax benefit (expense)"

Accumulated other comprehensive income is a running total on a company’s balance sheet that records certain gains and losses not included in reported profit, such as unrealized gains or losses on some investments, currency translation differences, and pension plan adjustments. Think of it like items in a shopping cart you haven’t paid for yet: it doesn’t affect current profit but changes the company’s overall equity and signals potential future swings in value that investors should watch.

Regulation S-X regulatory

"restated its previously issued consolidated financial statements ... for compliance with Regulation S-X"

A set of U.S. securities rules that prescribes how public companies must prepare, present and have audited their financial statements and related exhibits. It lays out formats, required schedules and minimum disclosure standards so financial reports follow a consistent structure. For investors, this consistency and verification act like a standard recipe and inspection checklist, making financial statements easier to compare, trust and use for valuation decisions.

Independent Auditor’s Report

Board of Directors

Lhoist North America, Inc.

Fort Worth, Texas

Opinion

We have audited the consolidated financial statements of Lhoist North America, Inc. and subsidiaries, which comprise the consolidated balance sheets as of December 31, 2025 and 2024, and the related consolidated statements of income and comprehensive income, equity, and cash flows for the years then ended, and the related notes to the consolidated financial statements.

In our opinion, the accompanying consolidated financial statements present fairly, in all material respects, the financial position of Lhoist North America, Inc. and subsidiaries as of December 31, 2025 and 2024, and the results of their operations and their cash flows for the years then ended in accordance with accounting principles generally accepted in the United States of America.

Basis for Opinion

We conducted our audits in accordance with auditing standards generally accepted in the United States of America (GAAS). Our responsibilities under those standards are further described in the “Auditor’s Responsibilities for the Audit of the Consolidated Financial Statements” section of our report. We are required to be independent of Lhoist North America, Inc. and to meet our other ethical responsibilities, in accordance with the relevant ethical requirements relating to our audits. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Emphasis of Matter – Restatement of the Financial Statements

As discussed in Note 1 to the consolidated financial statements, Lhoist North America, Inc., has restated its previously issued consolidated financial statements as of and for the years ended December 31, 2025 and 2024. The restatement reflects adjustments and additional disclosures necessary for compliance with Regulation S-X and other reporting requirements applicable to financial statements intended for inclusion in filings with the Securities and Exchange Commission in connection with the proposed acquisition of Lhoist North America, Inc. Our opinion is not modified with respect to this matter.

Responsibilities of Management for the Consolidated Financial Statements

Management is responsible for the preparation and fair presentation of the consolidated financial statements in accordance with accounting principles generally accepted in the United States of America, and for the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of consolidated financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the consolidated financial statements, management is required to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about Lhoist North America, Inc.’s ability to continue as a going concern within one year after the date that these consolidated financial statements are issued.

Board of Directors

Lhoist North America, Inc.

Auditor’s Responsibilities for the Audit of the Consolidated Financial Statements

Our objectives are to obtain reasonable assurance about whether the consolidated financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance but is not absolute assurance and therefore is not a guarantee that an audit conducted in accordance with GAAS will always detect a material misstatement when it exists. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control. Misstatements are considered material if there is a substantial likelihood that, individually or in the aggregate, they would influence the judgment made by a reasonable user based on the consolidated financial statements.

In performing an audit in accordance with GAAS, we:

• Exercise professional judgment and maintain professional skepticism throughout the audit.

• Identify and assess the risks of material misstatement of the consolidated financial statements, whether due to fraud or error, and design and perform audit procedures responsive to those risks. Such procedures include examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements.

• Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of Lhoist North America, Inc.’s internal control. Accordingly, no such opinion is expressed.

• Evaluate the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluate the overall presentation of the consolidated financial statements.

• Conclude whether, in our judgment, there are conditions or events, considered in the aggregate, that raise substantial doubt about Lhoist North America, Inc.’s ability to continue as a going concern for a reasonable period of time.

We are required to communicate with those charged with governance regarding, among other matters, the planned scope and timing of the audit, significant audit findings, and certain internal control-related matters that we identified during the audit.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation — The accompanying consolidated financial statements include the accounts of the Company. All intercompany balances and transactions have been eliminated between consolidated entities. The Company is a wholly owned subsidiary of LNA Holding SPRL, which is an indirect wholly owned subsidiary of Financière de Gestions Internationales — SCA, a Luxembourg corporation (the “ultimate parent”).

Cash and Cash Equivalents — The Company classifies as cash and cash equivalents amounts on deposit in banks and cash invested temporarily in various instruments with maturities of three months or less at the time of purchase.

Concentration of Credit Risk — Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash and cash equivalents and receivables. The Company maintains cash and cash equivalents with financial institutions that at times are in excess of Federal Deposit Insurance Corporation insurance limits. At December 31, 2025 and 2024, the Company’s cash accounts exceeded federally insured limits by approximately $31.1 million and $39.6 million, respectively.

Derivative Instruments — The Company manages its exposure to interest rates and commodity purchases by engaging in various types of derivative instruments including interest rate swaps, treasury locks, and commodity futures contracts. The Company records all derivatives in the consolidated balance sheets at fair value. The Company entered into transactions with credit-worthy counterparties and distributed contracts among several financial institutions to reduce the concentration of credit risk. The Company does not purchase or hold any financial derivative instruments for trading or speculative purposes.

Cash Flow and Non-Designated Hedges

Interest derivatives are designated and qualify as cash flow hedges. Commodity derivatives are designated as and qualify as Non-designated commodity derivative arrangements. The changes to fair value related to commodity hedges are recorded in Cost of sales. Interest derivative’s unrealized gain or loss is reported as a component of other comprehensive income (“OCI”) and recorded in accumulated other comprehensive income (“AOCI”) in the consolidated balance sheets. The changes to fair value that are recorded to OCI related to interest rate swaps are subsequently reclassified into other income (expense), net when the hedged item affects earnings. All cash flows associated with purchasing and selling derivatives are classified as operating cash flows in the Consolidated Statement of Cash Flows, within Changes in certain assets and liabilities. All cash flow derivative instruments are effective as of December 31, 2025 and 2024, respectively. See Notes 8 and Note 9 for further discussion of fair value and additional information about the derivative instruments.

Accounts Receivable and Allowance for Doubtful Accounts — Accounts receivable are recorded at the amount of consideration from customers of which the Company has an unconditional right to receive and do not bear interest. The allowance for credit losses is based on the best estimate of the amount of probable credit losses in existing accounts receivable. The Company provides an allowance for credit losses, which is based upon a review of outstanding receivables, historical collection information, and current economic conditions as of balance sheet date.

- 11 -

The Company has elected to use the practical expedient provided in ASC 326-20 that allows entities to assume that current conditions as of the balance sheet date do not change for the remaining life of the current accounts receivable and current contract assets. The Company has also made an accounting policy election to consider cash collection activity after the balance sheet date when estimating expected credit losses on current accounts receivable and current contract assets.

Inventories — Inventories are stated at the lower of cost or net realizable value. Cost is primarily determined using the weighted-average cost method.

Property, Plant, and Equipment — Property, plant, and equipment are recorded at cost. Depreciation expense is provided using the straight-line method over the estimated useful lives of the various assets as follows:

		Estimated Useful Life
Buildings and improvements			15-30 years
Machinery and equipment			3-25 years
Furniture and fixtures			3-10 years
Software			3 years

Maintenance, repairs, and minor replacements are charged to operations as incurred; major replacements and betterments are capitalized. When assets are sold or retired, the cost and related accumulated depreciation are removed from the accounts, and any resulting gain or loss is recognized in operations.

Depletion of mining rights is determined on the unit-of-production method for financial reporting purposes and on the statutory basis for federal income tax purposes.

Goodwill and Other Intangibles — Goodwill represents the excess of the cost over the fair value of net assets of purchased businesses. Other intangible assets represent amounts assigned principally to contractual agreements and are either amortized ratably over the useful lives to the Company or not amortized if deemed to have an indefinite useful life. The Company accounts for other intangibles in accordance with Accounting Standards Codification (ASC) 350-10, Intangibles — Goodwill and Other.

The Company reviews the carrying values of goodwill and other indefinite-lived intangible assets for impairment annually. An interim review is performed between annual tests if facts and circumstances indicate potential impairment. The carrying value of other amortizable intangible assets is reviewed if facts and circumstances indicate potential impairment. If a review indicates the carrying value is impaired, a charge is recorded equal to the amount by which the carrying value exceeds the fair value.

Operating Leases — The Company determines if a contract is or contains a lease at inception of the agreement. At lease commencement, operating and finance leases are recognized as ROU assets and the related obligations are recognized as current or noncurrent liabilities on the Company’s consolidated balance sheets. Leases with an initial lease term of one year or less are not recorded on the balance sheet. The Company combines lease and nonlease components, such as common area and other maintenance costs, and accounts for them as a single lease component in calculating the ROU assets and lease liabilities.

- 12 -

ROU assets, which represent the Company’s right to use an underlying asset, and lease liabilities, which represent the Company’s obligation to make lease payments arising from the lease, are recognized based on the present value of the future lease payments over the initial lease term at commencement date. Where a lease does not provide an implicit rate, the Company uses an interest rate swap curve adding a credit spread based on the Company’s credit rating methodology in determining the present value of lease payments. 

In addition, for certain equipment leases, the Company applies a portfolio approach to effectively account for the operating lease ROU assets and liabilities. Operating lease expense is recognized on a straight-line basis over the lease term.

Shipping and Handling Fees and Costs — The Company includes shipping and handling charges billed to customers in revenues. The related costs associated with shipping and handling is included as a component of cost of sales. The shipping and handling charges billed to customers were $243.7 million and $243.2 million for the years ended December 31, 2025 and 2024, respectively.

Income Taxes — Under ASC 740-10, Income Taxes, income taxes are provided based on earnings reported for tax return purposes in addition to a provision or benefit for deferred income taxes. The provision for income taxes includes deferred taxes determined by the change in deferred tax liability (or asset), which is computed based on the differences between the financial statement and income tax bases of assets and liabilities and measured by applying enacted tax laws and rates. Deferred tax expense or benefit is the result of changes in the deferred tax liability or asset. The Company evaluates uncertainties that may exist in its tax positions by considering whether it is more-likely-than-not threshold, then no tax benefit will be recognized. The Company has evaluated its open tax years from 2019 through 2025 and has recorded an allowance for uncertain positions, as described in Note 13. The Company files a consolidated federal income tax return with its subsidiaries and several consolidated and separate state income tax returns.

Foreign Currency Translation — The Company’s Canadian and Jamaican subsidiaries use the local currency as the functional currency. All balance sheet accounts of the foreign subsidiaries’ operations are translated into U.S. dollars at the year-end rate of exchange, and consolidated statements of income items are translated monthly from their respective functional currency to U.S. dollars at amounts that approximate weighted-average exchange rates. The resulting translation adjustments are recorded directly to a separate component of other comprehensive income (loss) and noncontrolling interest within shareholder’s equity, along with related tax effects. Gains and losses from foreign currency translations are included in the consolidated statements of income, consolidated statements of equity and the consolidated statements of comprehensive income. The foreign currency translation amounts within accumulated other comprehensive loss at December 31, 2025 and 2024, totaled $0.6 million and $1.4 million, respectively.

Use of Estimates — The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses in the reporting periods. Actual results could differ from those estimates.

- 13 -

Self-Insurance Programs — The Company is self-insured for various levels of group, health, and workers’ compensation. The recorded insurance reserves are actuarially determined.

Advertising — Advertising costs are expensed when incurred. The Company incurred advertising expenses of $0.2 million and $0.3 million for the years ended December 31, 2025 and 2024, respectively.

Re-engineering and System Conversion Costs — All costs incurred in connection with re-engineering, training, and business process improvement activities are expensed as incurred, including all related internal and third-party costs. System conversion costs and the costs of new hardware and software are accounted for in accordance with guidance under ASC 720, Other Expenses.

Noncontrolling Interests — The Company reports a 10.0% noncontrolling interest in one subsidiary as an ownership interest in the consolidated entity in the consolidated financial statements.

Comprehensive Income — ASC 220-10, Income Statement-Reporting Comprehensive Income, establishes standards for reporting comprehensive income and its components in a full set of financial statements. The guidance requires that all items that are to be recognized under accounting standards as components of comprehensive income, including an amount representing total comprehensive income, be reported in a financial statement that is displayed with the same prominence as other financial statements. The only components of other comprehensive income relate to designated hedging activities, foreign currency translation adjustments and pension liability, net of tax.

Revenue Recognition — Revenue is recognized when a customer obtains control of promised goods or services in an amount that reflects the consideration the entity expects to receive in exchange for those goods or services. In addition, the standard requires disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers.

The majority of the Company’s revenues are derived from short duration contracts and revenue is recognized at a single point in time when control is transferred to the customer, generally at shipment or when delivery has occurred, or services have been rendered. The Company records customer shipping and related costs as sales and cost of sales. Sales tax collected is not included in net sales. The Company determines revenue recognition through the following steps:

• Identification of the contract(s) with a customer.

• Identification of the performance obligations in the contract.

• Determination of the transaction price.

• Allocation of the transaction price to the performance obligations in the contract.

• Recognition of revenue when, or as, a performance obligation is satisfied.

Accounts receivable- net of allowance, beginning of year		$	169,384			$	175,939
Accounts receivable- net of allowance, end of year			195,856				169,384

Impairment of Long-Lived Assets — The Company accounts for impairment or disposal of long-lived assets, including discontinued operations, in accordance with ASC 360-10, Property, Plant, and Equipment.

Environmental Expenditures — Environmental expenditures that relate to current or future revenues are expensed or capitalized as appropriate. Expenditures that relate to an existing condition caused by past operations and do not contribute to current or future revenue generation are expensed.

Liabilities are recorded when environmental assessments and/or cleanups are probable, and the costs can be reasonably estimated. Environmental liabilities are not discounted to their present value. Subsequent adjustments to estimates, to the extent required, may be made as more refined information becomes available. 

- 15 -

Stripping Costs — The Company accounts for stripping costs incurred during the production and mining process in accordance with ASC 930, Extractive Activities — Mining. This guidance requires that stripping costs incurred during the production phase of the mine be included in the costs of the inventory produced during the period in which the stripping costs are incurred.

Asset Retirement Obligations — Asset retirement obligations associated with the retirement of the tangible, long-lived assets and the associated retirement cost follow the guidance under ASC 410-20, Asset Retirement and Environmental Obligations. The Company has recorded an obligation for the future reclamation costs related to quarries, plants, and dismantlement of certain plant equipment. Revisions to the obligation could occur due to changes in the Company’s estimated useful lives of the underlying assets, estimated dates of decommissioning, changes in decommissioning costs, changes in federal or state regulatory guidance on the decommissioning of such facilities, or other changes in estimates. Changes due to revised estimates will be recognized by adjusting the carrying amount of the liability and the related long-lived asset if the assets are still in service or charged to expense in the period if the assets are no longer in service. As new obligations are identified, the Company also records a corresponding fixed asset and amortizes the costs over the life of the asset. The activity included in other liabilities for years 2025 and 2024 is as follows (in thousands):

Asset retirement obligation — December 31, 2023		$	57,545
New layer			39,158
Revision in estimated cash flows			11,891
Accretion			1,555
Asset retirement obligation — December 31, 2024		$	110,149
New layer			1,496
Accretion			3,463
Asset retirement obligation — December 31, 2025		$	115,108

Recent Accounting Pronouncements — In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which focuses on the rate reconciliation and income taxes paid. ASU No. 2023-09 requires entities to disclose, on an annual basis, specific categories in the effective tax rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. In addition, ASU No. 2023-09 requires companies to disclose further information about income taxes paid.

7. GOODWILL AND OTHER INTANGIBLES

Goodwill

The Company tests goodwill for impairment at the reporting unit level annually. In testing goodwill for impairment, the Company has the option first to perform a qualitative assessment to determine whether it is more-likely-than-not that goodwill is impaired or the entity can bypass the qualitative assessment and proceed directly to the quantitative test by comparing the carrying amount, including goodwill, of the reporting unit with its fair value. The goodwill impairment loss, if any, is measured as the amount by which the carrying amount of a reporting unit, including goodwill, exceeds its fair value. Subsequent increases in goodwill value are not recognized in the financial statements.

Other Intangible Assets

The Company periodically evaluates its determination of the useful lives of other amortizable intangible assets. Any resulting changes in the useful lives of such other intangible assets will not impact the cash flows of the Company. However, a decrease in the useful lives of such other intangible assets would increase future amortization expense and decrease future reported operating results. As of December 31, 2025 and 2024, there were no triggering events that resulted in an impairment analysis. The Company concluded no adjustments of such assets were required.

The Company’s other intangible assets subject to amortization consist of patents and customer relationships. The Company’s intangible assets not subject to amortization consist of trademarks, permitting rights, mineral rights, and water rights.

8. FAIR VALUE MEASUREMENTS

The Company’s assets and liabilities recognized at fair value have been categorized based upon a fair value hierarchy as described below. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements must maximize the use of observable inputs and minimize the use of unobservable inputs. The hierarchy comprises three levels of inputs that may be used to measure fair value:

Level 1 Quoted prices in active markets for identical assets or liabilities

Level 2 Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities

Level 3 Unobservable inputs supported by little or no market activity and that are significant to the fair value of the assets or liabilities

Assets and Liabilities Measured at Fair Value

As of December 31, 2025 and 2024, the Company’s financial instruments measured at fair value include commodity derivatives, interest rate swaps, and a deferred compensation plan, all are measured on a recurring basis.

The interest rate swaps convert certain floating-rate debt to a fixed-rate. All derivative and swap instruments are classified as Level 2 valuations. The Company determines the fair value of its derivative financial instrument positions based upon pricing models using inputs observed from actively quoted markets and also takes into consideration the contract terms as well as other inputs, including market interest rates; see Note 9 for additional information on derivatives.

The following tables provide information by level for financial assets and liabilities that are measured at fair value on a recurring basis as of December 31, 2025 and 2024, respectively (in thousands):

Financial Instruments not Measured at Fair Value

As of December 31, 2025 and 2024, the Company’s financial instruments not measured at fair value include temporary cash investments, advances to affiliates, and long-term debt. These financial instruments are carried on the consolidated balance sheets at cost, which approximates fair value.

As discussed in Note 1, temporary cash investments have maturities of less than three months and are placed primarily in money market funds and money market demand deposit accounts with financial institutions. The Company’s temporary cash investments totaled $19.6 million and $27.7 million as of December 31, 2025 and 2024, respectively.

Advances to affiliate are monies held in a pooled cash account with an affiliate and totaled $247.1 million and $395.1 million as of December 31, 2025 and 2024, respectively. The monies are expected to be used for business operations during the 2026 fiscal year; see Note 16 for additional information.

As discussed in Note 12, the Company’s held $955.6 million and $1,019.1 million in long-term debt instruments as of December 31, 2025 and 2024, respectively.

9. FINANCIAL DERIVATIVE INSTRUMENTS

The Company entered into derivative instruments to manage commodity price and interest rate risk.

Commodity Hedging

The Company entered into several fixed price swap agreements with a financial institution for energy related derivatives to reduce exposure to changes in these commodity prices. The Company generally hedges 35% - 95% of the expected energy usage in a year.

The Company has elected to utilize netting for its energy related derivative instruments and classifies such amounts as current and noncurrent, based on the net fair value position with each of the Company’s counterparties in the consolidated balance sheet as there is a right to offset.

The table below presents certain information regarding the Company’s Non-designated commodity derivative arrangement (in thousands):

		2025				2024
Fair value of commodity derivative agreements recognized in
Accrued expenses		$	861			$	297
Other liabilities			3,663				—
Deferred tax asset (liability)			1,131				74
(Loss) gain recognized in Cost of sales for the year ended December 31,			(4,228	)			10,706
Tax Effect of Hedge Included in Deferred Tax Provision			1,057				(2,676	)

As of December 31, 2025, the Company has the following outstanding commodity derivative arrangements that were entered into to hedge forecasted purchases for the years 2026-2030:

Natural Gas 25,405,000 MMBtu

Interest Rate Swaps

On November 29, 2021, the Company executed two five year forward-starting pay fixed interest rate derivative instruments with an affiliate with a combined original notional amount of $316.3 million. The combined notional amounts under these agreements as of December 31, 2025 and 2024 are $63.3 million and $126.6 million, respectively. The combined notional amounts amortize on a quarterly basis over the term to a combined statement amount per the agreement. The purpose of the instruments is to hedge the exposure to interest rates related to the term loan discussed in Note 12; thus, both the debt and derivatives have the same effective and maturity dates. Under the instruments the Company makes payments at a fixed weighted average rate of 0.88% and receives payments equal to the Secured Overnight Financing Rate. Under the agreement, the Company pays or receives the net interest amount quarterly, with the quarterly settlements included in other income (expense), net.

- 23 -

These instruments are being accounted for as cash flow hedges and mature in November 2026. The Company’s interest rate swap agreements qualify for the “shortcut” method of accounting for hedges, which dictates that the hedges are assumed to be perfectly effective.

The table below presents certain information regarding the Company’s interest rate swap agreement designated as a cash flow hedge (in thousands):

		2025				2024
Fair value of interest rate swap agreements recognized in
Other assets		$	1,584			$	5,724
Deferred tax liability			478				1,639
Gain recognised in other comprehensive income, net of tax related benefit			1,106				4,085
Gain reclassified from accumulated other comprehensive income into other income (expense), net			2,979				4,565

The Company estimates approximately $0.9 million to be reclassified into earnings over the next 12 months.

Treasury lock

The Company entered into a treasury lock agreement in 2021. This treasury lock agreement was a synthetic forward sale of US treasury securities settled in cash and was computed as the difference between an agreed-upon treasury rate and the prevailing treasury rate at settlement. The treasury lock was finalized in April of 2022 and resulted in an $8.1 million realized gain. This gain is recognized in other comprehensive income and is being amortized over the 10 year life of the 2022 unsecured fixed-rate senior notes discussed in Note 12. The Company made a policy election to have the settlement run through operating activities on the cash flow in connection with this derivative.

The Company estimates approximately $0.8 million to be reclassified into earnings over the next 12 months.

13. INCOME TAXES

The income tax provision for the years ended December 31, is as follows (in thousands):

		2025				2024
Current:
Federal		$	99,315			$	99,627
State and foreign			18,143				18,462

The statutory depletion deduction for all years is calculated as a percentage of revenues, subject to certain limitations. Due to these limitations, changes in the sales volumes and pretax earnings may not proportionately affect the Company’s statutory depletion deduction and the corresponding impact on the effective income tax rate.

The Company’s effective income tax rate reflects the effect of federal and state income taxes on earnings and the impact of differences in book and tax accounting arising primarily from the permanent tax benefits associated with the statutory depletion deduction for mineral reserves. The effective income tax rates for continuing operations were 19.9% and 20.4% for the years ended 2025 and 2024, respectively.

At December 31, 2025, the Company has state net operating loss carryforwards of $2.5 million, which, if not utilized will begin to expire in 2026.

Accounting for uncertainty in tax positions requires companies to recognize only the impact of tax positions, that based on their technical merits, are more-likely-than-not to be sustained upon an audit by the taxing authority. The amount to be recognized is measured as the largest amount of tax benefit that is greater than 50% likely of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. The Company’s unrecognized tax benefits are recorded in other liabilities on the consolidated balance sheet or as an offset to the deferred tax asset for tax carryforwards where available.

- 28 -

The Company does not expect the unrecognized tax benefit, totaling $9.3 million, which is currently recorded in Accrued expense as taxes, to be settled or significantly reduced in the next 12 months. Accrued interest and penalties on unrecognized tax benefits and other interest and penalty expense was immaterial to the consolidated financial statements for all periods presented. 

The Company files a federal consolidated and several consolidated and separate state income tax returns in the U.S. federal jurisdiction and various states and foreign jurisdictions. 

The Company expects to reinvest the earnings from its wholly-owned Canadian and Jamaican subsidiaries indefinitely, and accordingly, has not provided deferred taxes on the subsidiaries’ undistributed net earnings or basis differences. The Company believes that the tax liability that would be incurred upon repatriation of the foreign earnings was immaterial at December 31, 2025 and 2024.

14. EMPLOYEE BENEFIT PLANS

The Company maintains several postretirement medical plans and a supplemental employee retirement plan (“SERP”). 

Under ASC 715-20, Compensation — Retirement Benefits, plan sponsors are required to (a) recognize in its statement of financial position an asset for a plan’s overfunded status or a liability for a plan’s underfunded status, (b) measure a plan’s assets and its obligations that determine its funded status as of the end of the employer’s fiscal year, and (c) recognize changes in the funded status of a defined benefit postretirement plan in the year in which the changes occur. Such changes will be reported in other comprehensive income (loss).

Plan sponsors are also required to record and subsequently amortize unrecognized prior service costs and unrecognized gains (losses) in accumulated other comprehensive income (loss). The amortization of these incurred costs will ultimately be included in expenses in subsequent years. 

The following table summarizes the consolidated balance sheet impact, as well as the benefit obligations, funded status, and assumptions associated with the postretirement medical plans, and SERP.

At December 31, obligations and funded status are as follows (in thousands):

Weighted-average assumptions used to determine net periodic benefit cost for the years ended December 31, is as follows: 

		Postretirement Medical Plans								SERP
		2025				2024				2025				2024
Discount rates			5.14	%			4.56	%			4.68	%			5.14	%

Certain actuarial assumptions, such as the assumed health care cost trend rates and the long-term rate of return have a significant effect on the amounts reported for postretirement medical benefit and the respective benefit obligation amounts. The Company reviews external data and its own historical trends for health care costs to determine the health care cost trend rates for the postretirement medical benefit plans. For 2025, the Company assumed an 8.0% annual rate of increase in the per-capita cost of covered health care claims with the rate decreasing in even increments over five years until reaching 4.5%.

LHOIST NORTH AMERICA, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

AS OF AND FOR THE SIX MONTHS ENDED JUNE 30, 2026 AND 2025

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Operations — Lhoist North America, Inc. and subsidiaries (the “Company”) are primarily engaged in the manufacture and sale of lime and limestone products to various industries throughout the United States.

Principles of Consolidation — The accompanying consolidated financial statements include the accounts of the Company. All intercompany balances and transactions have been eliminated between consolidated entities. The Company is a wholly owned subsidiary of LNA Holding SPRL, which is an indirect wholly owned subsidiary of Financière de Gestions Internationales — SCA, a Luxemburg corporation (the “ultimate parent”).

On June 29, 2026, Martin Marietta Materials, Inc. (the Purchaser), a North Carolina corporation announced in an Form 8-K filing the execution of a Securities Sale Agreement, dated June 27, 2026, between the Purchaser and LNA Holding SRL, a société à responsabilité limitée organized under the laws of Belgium, pursuant to which the Purchaser will acquire all of the outstanding equity interests in the Company.

As a result of this agreement, the Company’s accompanying consolidated financial statements have been “uplifted” and prepared in accordance with U.S. Generally Accepted Accounting Principles (U.S. GAAP) and the applicable rules and regulations of the SEC (including Regulation S-X) related to financial statements to be included in an SEC filing.

Cash and Cash Equivalents — The Company classifies as cash and cash equivalents amounts on deposit in banks and cash invested temporarily in various instruments with maturities of three months or less at the time of purchase.

Concentration of Credit Risk — Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash and cash equivalents and receivables. The Company maintains cash and cash equivalents with financial institutions that at times are in excess of Federal Deposit Insurance Corporation insurance limits. At June 30, 2026 and 2025, the Company’s cash accounts exceeded federally insured limits by approximately $35.2 million and $28.0 million, respectively.

Derivative Instruments — The Company manages its exposure to interest rates and commodity purchases by engaging in various types of derivative instruments including interest rate swaps, treasury locks, and commodity futures contracts. The Company records all derivatives in the consolidated balance sheets at fair value. The Company entered into transactions with credit-worthy counterparties and distributed contracts among several financial institutions to reduce the concentration of credit risk. The Company does not purchase or hold any financial derivative instruments for trading or speculative purposes.

- 6 -

Cash Flow and Non-Designated Hedges

Interest derivatives are designated and qualify as cash flow hedges. Commodity derivatives are designated as and qualify as non-designated commodity derivative arrangements. The changes to fair value related to commodity hedges are recorded in Cost of sales. Interest derivative’s unrealized gains or loss is reported as a component of other comprehensive income (“OCI”) and recorded in accumulated other comprehensive income (“AOCI”) in the consolidated balance sheets. The changes to fair value that are recorded to OCI related to interest rate swaps are subsequently reclassified into other income (expense), net when the hedged item affects earnings. All cash flows associated with purchasing and selling derivatives are classified as operating cash flows in the Consolidated Statement of Cash Flows, within Changes in certain assets and liabilities. All cash flow derivative instruments are effective as of June 30, 2026 and 2025, respectively. See Notes 7 and 8 for further discussion of fair value and additional information about the derivative instruments.

Accounts Receivable and Allowance for Credit Losses — Accounts receivable are recorded at the amount of consideration from customers of which the Company has an unconditional right to receive and do not bear interest. The allowance for credit losses is based on the best estimate of the amount of probable credit losses in existing accounts receivable. The Company provides an allowance for credit losses, which is based upon a review of outstanding receivables, historical collection information, and current economic conditions as of the balance sheet date.

The Company has elected to use the practical expedient provided in ASC 326-20 that allows entities to assume that current conditions as of the balance sheet date do not change for the remaining life of the current accounts receivable and current contract assets. The Company has also made an accounting policy election to consider cash collection activity after the balance sheet date when estimating expected credit losses on current accounts receivable and current contract assets.

Inventories — Inventories are stated at the lower of cost or net realizable value. Cost is primarily determined using the weighted-average cost method.

Spare Part Stock – The Company maintains certain spare parts to support ongoing operations, particularly where the parts are critical to production, subject to long procurement lead times, or used only in connection with specific items of equipment. Spare parts that do not meet the definition of inventory and that are not depreciated separately as property, plant, and equipment, are classified as other assets on the balance sheet. These spare parts are recorded at cost less an allowance for obsolescence.

Property, Plant, and Equipment — Property, plant, and equipment are recorded at cost. Depreciation expense is provided using the straight-line method over the estimated useful lives of the various assets as follows:

		Estimated Useful Life
Buildings and improvements			15-30 years
Machinery and equipment			3-25 years
Furniture and fixtures			3-10 years
Software			3 years

- 7 -

Maintenance, repairs, and minor replacements are charged to operations as incurred; major replacements and betterments are capitalized. When assets are sold or retired, the cost and related accumulated depreciation are removed from the accounts, and any resulting gain or loss is recognized in operations.

Depletion of mining rights is determined on the unit-of-production method for financial reporting purposes, and on the statutory basis for federal income tax purposes.

Goodwill and Other Intangibles — Goodwill represents the excess of the cost over the fair value of net assets of purchased businesses. Other intangible assets represent amounts assigned principally to contractual agreements and are either amortized ratably over the useful lives to the Company or not amortized if deemed to have an indefinite useful life. The Company accounts for other intangibles in accordance with Accounting Standards Codification (ASC) 350-10, Intangibles — Goodwill and Other.

The Company reviews the carrying values of goodwill and other indefinite-lived intangible assets for impairment annually. An interim review is performed between annual tests if facts and circumstances indicate potential impairment. The carrying value of other amortizable intangible assets is reviewed if facts and circumstances indicate potential impairment. If a review indicates the carrying value is impaired, a charge is recorded equal to the amount by which the carrying value exceeds the fair value.

Operating Leases — The Company determines if a contract is or contains a lease at inception of the agreement. At lease commencement, operating and finance leases are recognized as Right of use (ROU) assets and the related obligations are recognized as current or noncurrent liabilities on the Company’s consolidated balance sheets. Leases with an initial lease term of one year or less are not recorded on the balance sheet. The Company combines lease and non-lease components, such as common area and other maintenance costs, and accounts for them as a single lease component in calculating the ROU assets and lease liabilities.

ROU assets, which represent the Company’s right to use an underlying asset, and lease liabilities, which represent the Company’s obligation to make lease payments arising from the lease, are recognized based on the present value of the future lease payments over the initial lease term at commencement date. Where a lease does not provide an implicit rate, the Company uses an interest rate swap curve adding a credit spread based on the Company’s credit rating methodology in determining the present value of lease payments. 

In addition, for certain equipment leases, the Company applies a portfolio approach to effectively account for the operating lease ROU assets and liabilities. Operating lease expense is recognized on a straight-line basis over the lease term.

Shipping and Handling Fees and Costs — The Company includes shipping and handling charges billed to customers in revenues. The related costs associated with shipping and handling is included as a component of cost of sales. The shipping and handling charges billed to customers were $136.7 million and $116.8 million for the six months ended June 30, 2026, and 2025, respectively.

- 8 -

Income Taxes — Under ASC 740-10, Income Taxes, income taxes are provided based on earnings reported for tax return purposes in addition to a provision or benefit for deferred income taxes. The provision for income taxes includes deferred taxes determined by the change in deferred tax liability (or asset), which is computed based on the differences between the financial statement and income tax bases of assets and liabilities and measured by applying enacted tax laws and rates. Deferred tax expense or benefit is the result of changes in the deferred tax liability or asset. The Company evaluates uncertainties that may exist in its tax positions by considering whether it is more-likely-than-not threshold, then no tax benefit will be recognized. The Company has evaluated its open tax periods from 2019 through 2026 and has recorded an allowance for uncertain positions, as described in Note 12. The Company files a consolidated federal income tax return with its subsidiaries and several consolidated and separate state income tax returns.

Foreign Currency Translation — The Company’s Canadian and Jamaican subsidiaries use the local currency as the functional currency. All balance sheet accounts of the foreign subsidiaries’ operations are translated into U.S. dollars at the month-end rate of exchange, and consolidated statements of income items are translated monthly from their respective functional currency to U.S. dollars at amounts that approximate weighted-average exchange rates. The resulting translation adjustments are recorded directly to a separate component of other comprehensive income (loss) and noncontrolling interest within shareholder’s equity, along with related tax effects. Gains and losses from foreign currency translations are included in the consolidated statements of income, consolidated statements of equity and the consolidated statements of comprehensive income. The foreign currency translation amounts within accumulated other comprehensive income (loss) at June 30, 2026 and 2025, totaled ($0.4) million and $0.9 million for the six months ended, respectively.

Use of Estimates — The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosures of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses in the reporting periods. Actual results could differ from those estimates.

Self-Insurance Programs — The Company is self-insured for various levels of group, health, and workers’ compensation. The recorded insurance reserves are actuarially determined.

Advertising — Advertising costs are expensed when incurred. The Company incurred advertising expenses of $0.1 million and $0.2 million for the six months ended June 30, 2026 and 2025, respectively.

Re-engineering and System Conversion Costs — All costs incurred in connection with re-engineering, training, and business process improvement activities are expensed as incurred, including all related internal and third-party costs. System conversion costs and the costs of new hardware and software are accounted for in accordance with guidance under ASC 720, Other Expenses.

Noncontrolling Interests — The Company reports a 10.0% noncontrolling interest in one subsidiary as an ownership interest in the consolidated entity in the consolidated financial statements.

- 9 -

Comprehensive Income — ASC 220-10, Income Statement-Reporting Comprehensive Income, establishes standards for reporting comprehensive income and its components in a full set of financial statements. The guidance requires that all items that are to be recognized under accounting standards as components of comprehensive income, including an amount representing total comprehensive income be reported in a financial statement that is displayed with the same prominence as other financial statements. The only components of other comprehensive income relate to designated hedging activities, foreign currency translation adjustments, and pension liability, net of tax.

Revenue Recognition — Revenue is recognized when a customer obtains control of promised goods or services in an amount that reflects the consideration the entity expects to receive in exchange for those goods or services. In addition, the standard requires disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers.

The majority of the Company’s revenues are derived from short duration contracts and revenue is recognized at a single point in time when control is transferred to the customer, generally at shipment or when delivery has occurred, or services have been rendered. The Company records customer shipping and related costs as sales and cost of sales. Sales tax collected is not included in net sales. The Company determines revenue recognition through the following steps: 

• Identification of the contract(s) with a customer.

• Identification of the performance obligations in the contract.

• Determination of the transaction price.

• Allocation of the transaction price to the performance obligations in the contract.

• Recognition of revenue when, or as, a performance obligation is satisfied.

Impairment of Long-Lived Assets — The Company accounts for impairment or disposal of long-lived assets, including discontinued operations, in accordance with ASC 360-10, Property, Plant, and Equipment.

Environmental Expenditures — Environmental expenditures that relate to current or future revenues are expensed or capitalized as appropriate. Expenditures that relate to an existing condition caused by past operations and do not contribute to current or future revenue generation are expensed.

Liabilities are recorded when environmental assessments and/or cleanups are probable, and the costs can be reasonably estimated. Environmental liabilities are not discounted to their present value. Subsequent adjustments to estimates, to the extent required, may be made as more refined information becomes available.

Stripping Costs — The Company accounts for stripping costs incurred during the production and mining process in accordance with ASC 930, Extractive Activities — Mining. This guidance requires that stripping costs incurred during the production phase of the mine be included in the costs of the inventory produced during the period in which the stripping costs are incurred.

- 11 -

Asset Retirement Obligations — Asset retirement obligations associated with the retirement of the tangible, long-lived assets and the associated retirement cost follow the guidance under ASC 410-20, Asset Retirement and Environmental Obligations. The Company has recorded an obligation for the future reclamation costs related to quarries, plants, and dismantlement of certain plant equipment. Revisions to the obligation could occur due to changes in the Company’s estimated useful lives of the underlying assets, estimated dates of decommissioning, changes in decommissioning costs, changes in federal or state regulatory guidance on the decommissioning of such facilities, or other changes in estimates. Changes due to revised estimates will be recognized by adjusting the carrying amount of the liability and the related long-lived asset if the assets are still in service or charged to expense in the period if the assets are no longer in service. As new obligations are identified, the Company also records a corresponding fixed asset and amortizes the costs over the life of the asset. The activity included in other liabilities for the six months ended June 30, 2026 and 2025 is as follows (in thousands):

Recent Accounting Pronouncements — 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 (DISE), which requires public entities to disaggregate any relevant expense caption presented on the face of the income statement within continuing operations into the following required natural expense categories, as applicable: (1) purchases of inventory, (2) employee compensation, (3) depreciation, (4) intangible asset amortization, and (5) depreciation, depletion and amortization recognized as part of oil- and gas-producing activities or other depletion expenses. These disclosures must be made in a tabular format in the footnotes to the financial statements. The new standard does not change the requirements for the presentation of expenses on the face of the statement of earnings. The ASU is effective prospectively for annual reporting periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027, and early adoption and retrospective application are permitted. The ASU will have no impact on the Company’s results of operations, cash flows or financial condition.

6. GOODWILL AND OTHER INTANGIBLES

Goodwill

The Company tests goodwill for impairment at the reporting unit level annually. In testing goodwill for impairment, the Company has the option first to perform a qualitative assessment to determine whether it is more-likely-than-not that goodwill is impaired or the entity can bypass the qualitative assessment and proceed directly to the quantitative test by comparing the carrying amount, including goodwill, of the reporting unit with its fair value. The goodwill impairment loss, if any, is measured as the amount by which the carrying amount of a reporting unit, including goodwill, exceeds its fair value. Subsequent increases in goodwill value are not recognized in the financial statements.

- 15 -

Other Intangible Assets

The Company periodically evaluates its determination of the useful lives of other amortizable intangible assets. Any resulting changes in the useful lives of such other intangible assets will not impact the cash flows of the Company. However, a decrease in the useful lives of such other intangible assets would increase future amortization expense and decrease future reported operating results. As of June 30, 2026 and 2025, there were no triggering events that resulted in an impairment analysis. The Company concluded no adjustments of such assets were required.

The Company’s other intangible assets subject to amortization consist of patents and customer relationships. The Company’s other intangible assets not subject to amortization consist of trademarks, permitting rights, mineral rights, and water rights.

A summary of other intangibles as of June 30, 2026 and 2025, is as follows (in thousands):

7. FAIR VALUE MEASUREMENTS

The Company’s assets and liabilities recognized at fair value have been categorized based upon a fair value hierarchy as described below. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value measurements must maximize the use of observable inputs and minimize the use of unobservable inputs. The hierarchy comprises three levels of inputs that may be used to measure fair value:

Level 1 Quoted prices in active markets for identical assets or liabilities

Level 2 Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities

Level 3 Unobservable inputs supported by little or no market activity and that are significant to the fair value of the assets or liabilities

Assets and Liabilities Measured at Fair Value

As of June 30, 2026 and 2025, the Company’s financial instruments measured at fair value include commodity derivatives, interest rate swaps, and a deferred compensation plan, all are measured on a recurring basis.

The interest rate swaps convert certain floating-rate debt to a fixed-rate. All derivative and swap instruments are classified as Level 2 valuations. The Company determines the fair value of its derivative financial instrument positions based upon pricing models using inputs observed from actively quoted markets and also takes into consideration the contract terms as well as other inputs, including market interest rates; see Note 8 for additional information on derivatives.

The following tables provide information by level for financial assets and liabilities that are measured at fair value on a recurring basis as of June 30, 2026 and 2025, respectively (in thousands):

Financial Instruments not Measured at Fair Value

As of June 30, 2026 and 2025, the Company’s financial instruments not measured at fair value include temporary cash investments, advances to affiliates, and long term debt. These financial instruments are carried on the consolidated balance sheets at cost, which approximates fair value.

As discussed in Note 1, Temporary cash investments have maturities of less than three months and are placed primarily in money market funds and money market demand deposit accounts with financial institutions. The Company’s temporary cash investments totaled $26.4 million and $19.1 million as of June 30, 2026 and 2025, respectively.

Advances to affiliate are monies held in a pooled cash account with an affiliate and totaled $278.6 million and $328.1 million as of June 30, 2026 and 2025, respectively. The monies are expected to be used for business operations during the next 12 months; see Note 16 for additional information.

As discussed in Note 11, the Company’s held $923.9 million and $737.4 million in long-term debt instruments as of June 30, 2026 and 2025, respectively.

8. FINANCIAL DERIVATIVE INSTRUMENTS

The Company entered into derivative instruments to manage commodity price and interest rate risk.

Commodity Hedging

The Company entered into several fixed price swap agreements with a financial institution for energy related derivatives to reduce exposure to changes in these commodity prices. The Company generally hedges 35% - 95% of the expected energy usage in a year.

The Company has elected to utilize netting for its energy related derivative instruments and classifies such amounts as current and non-current, based on the net fair value position with each of the Company’s counterparties in the consolidated balance sheet as there is a right to offset.

As of June 30, 2026, the Company has the following outstanding commodity derivative arrangements that were entered into to hedge forecasted purchases for the years 2026-2030:

Natural Gas 19,187,900 MMBtu

Interest Rate Swaps

On November 29, 2021, the Company executed two five year forward-starting pay fixed interest rate derivative instruments with an affiliate with a combined original notional amount of $316.3 million. The combined notional amounts under these agreements as of June 30, 2026 and 2025 is $63.3 million and $126.6 million, respectively. The combined notional amounts amortize on a quarterly basis over the term to a combined statement amount per the agreement. The purpose of the instruments is to hedge the exposure to interest rates related to the term loan discussed in Note 11; thus, both the debt and derivatives have the same effective and maturity dates. Under the instruments the Company makes payments at a fixed weighted average rate of 0.88% and receives payments equal to the Secured Overnight Financing Rate. Under the agreement, the Company pays or receives the net interest amount quarterly, with the quarterly settlements included in other income (expense), net.

These instruments are being accounted for as cash flow hedges and mature in November 2026. The Company’s interest rate swap agreements qualify for the “shortcut” method of accounting for hedges, which dictates that the hedges are assumed to be perfectly effective.

The Company estimates approximately $0.4 million to be reclassified into earnings over the next 6 months.

Treasury lock

The Company entered into a treasury lock agreement in 2021. This treasury lock agreement was a synthetic forward sale of US treasury securities settled in cash and was computed as the difference between an agreed-upon treasury rate and the prevailing treasury rate at settlement. The treasury lock was finalized in April of 2022 and resulted in an $8.1 million realized gain. This gain is recognized in other comprehensive income and is being amortized over the 10 year life of the 2022 unsecured fixed-rate senior notes discussed in Note 11. The Company made a policy election to have the settlement run through operating activities within the statement of cash flows in connection with this derivative.

12. INCOME TAXES

The income tax provision for the six months ended June 30, is as follows (in thousands):

		2026				2025
Current:
Federal		$	55,834			$	56,068
State and foreign			12,313				9,561
			68,147				65,629

State and foreign			(394	)			337
			(1,805	)			1,846
Total		$	66,342			$	67,475

The statutory depletion deduction for all years is calculated as a percentage of revenues, subject to certain limitations. Due to these limitations, changes in the sales volumes and pretax earnings may not proportionately affect the Company’s statutory depletion deduction and the corresponding impact on the effective income tax rate.

The Company’s effective income tax rate reflects the effect of federal and state income taxes on earnings and the impact of differences in book and tax accounting arising primarily from the permanent tax benefits associated with the statutory depletion deduction for mineral reserves. The effective income tax rates for continuing operations were 20.9% and 20.5% for the six months ended June 30, 2026 and 2025 respectively.

At June 30, 2026, the Company has state net operating loss carryforwards of $2.5 million, which, if not utilized will begin to expire in 2026.

Accounting for uncertainty in tax positions requires companies to recognize only the impact of tax positions, that based on their technical merits, are more-likely-than-not to be sustained upon an audit by the taxing authority. The amount to be recognized is measured as the largest amount of tax benefit that is greater than 50% likely of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. The Company’s unrecognized tax benefits are recorded in other liabilities on the consolidated balance sheet or as an offset to the deferred tax asset for tax carryforwards where available.

- 24 -

The Company does not expect the unrecognized tax benefit, totaling $9.3 million, which is currently recorded in other liabilities, to be settled or significantly reduced in the next 12 months. Accrued interest and penalties on unrecognized tax benefits and other interest and penalty expense was immaterial to the consolidated financial statements for all periods presented.

The Company expects to reinvest the earnings from its wholly-owned Canadian and Jamaican subsidiaries indefinitely, and accordingly, has not provided deferred taxes on the subsidiaries’ undistributed net earnings or basis differences. The Company believes that the tax liability that would be incurred upon repatriation of the foreign earnings was immaterial at June 30, 2026 and 2025.

The Company files a federal consolidated and several consolidated and separate state income tax returns in the U.S. federal jurisdiction and various states and foreign jurisdictions.

13. EMPLOYEE BENEFIT PLANS

The Company maintains several postretirement medical plans and a Supplemental Employee Retirement Plan (“SERP”).

Under ASC 715-20, Compensation — Retirement Benefits, plan sponsors are required to (a) recognize in its statement of financial position an asset for a plan’s overfunded status or a liability for a plan’s underfunded status, (b) measure a plan’s assets and its obligations that determine its funded status as of the period ended June 30, 2026, and (c) recognize changes in the funded status of a defined benefit postretirement plan in the year in which the changes occur. Such changes will be reported in other comprehensive income (loss).

Plan sponsors are also required to record and subsequently amortize unrecognized prior service costs and unrecognized gains (losses) in accumulated other comprehensive income (loss). The amortization of these incurred costs will ultimately be included in expenses in subsequent years.

The following table summarizes the consolidated balance sheet impact, as well as the benefit obligations, funded status, and assumptions associated with the postretirement medical plans, and SERP.

At June 30, obligations and funded status are as follows (in thousands):

Year that the rate reaches the ultimate trend rate			2031				2031				—				—

- 27 -

Certain actuarial assumptions, such as the assumed health care cost trend rates and the long-term rate of return have a significant effect on the amounts reported for postretirement medical benefit and the respective benefit obligation amounts. The Company reviews external data and its own historical trends for health care costs to determine the health care cost trend rates for the postretirement medical benefit plans. At June 30, 2026, the Company assumed an 8.0% annual rate of increase in the per-capita cost of covered health care claims with the rate decreasing in even increments over five years until reaching 4.5%.

The following table presents estimated future benefit payments (in thousands):

Defined Contribution Plan

The Company sponsors a safe harbor savings plan, under Sections 401(k) and 401(m) of the Internal Revenue Code. The 401(k) Plan provides employees the opportunity to invest up to 50% of their eligible compensation on a pre-tax or after-tax basis. The Company makes safe harbor matching contributions for all eligible employees in the amount of 100% of the first 3% of participant compensation and 50% on the next 2% of participant compensation. The Company also sponsors a discretionary employer contribution for all non-union employees and those union employees whose unions adopted the Safe Harbor Plan provision and plan amendment. This discretionary contribution is based on the eligible participants’ years of service.

Vesting of the Company’s safe harbor contributions is immediate. Discretionary contributions are cliff vested 100% after an employee completes three years of service with the Company. Employer contributions were approximately $7.1 million and $6.3 million in the six months ended of June 2026 and 2025, respectively.

EXHIBIT 99.3

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL

STATEMENTS

On June 27, 2026, Martin Marietta Materials, Inc. (“Martin Marietta”) and LNA Holding SRL (“LNA Holding”) entered into a securities sale agreement (the “SSA”) pursuant to which Martin Marietta will acquire all of the outstanding equity interests in Lhoist North America, Inc. (“Lhoist”), a wholly owned subsidiary of LNA Holding (the “Transaction”). In accordance with the SSA, the consideration payable by Martin Marietta to LNA Holding is approximately $13.5 billion, consisting of (i) $7.0 billion of cash, subject to certain adjustments, and (ii) 10,953,543 shares of newly-issued Martin Marietta common stock, with a value of approximately $6.5 billion based on the volume-weighted average trading price of Martin Marietta common stock for the 15 trading days ending on June 26, 2026. The Transaction is expected to close in the third quarter of 2026, subject to customary closing conditions.

In connection with the Transaction, Martin Marietta obtained a bridge loan commitment of up to $7.0 billion to temporarily fund the Transaction, if necessary. On July 15, 2026, Martin Marietta obtained a three-year unsecured term loan commitment in the aggregate principal amount of $1.5 billion to replace a part of such bridge loan commitment. These unaudited pro forma condensed combined financial statements (the “pro forma financial statements”) assume that Martin Marietta will obtain an additional $5.5 billion of permanent senior unsecured debt to replace the remaining bridge loan commitments prior to the closing of the Transaction.

Prior to the Transaction, Martin Marietta completed three separate transactions that are included in the pro forma financial statements:

• the acquisition of Premier Magnesia, LLC (“Premier”) on July 25, 2025;

• an asset exchange with QUIKRETE Holdings, Inc. (“QUIKRETE”) on February 23, 2026; and

• the acquisition of New Frontier Materials, LLC (“New Frontier” and, together with Premier and QUIKRETE, the “Other Acquisitions”) on May 15, 2026.

The pro forma financial statements have been derived from the historical consolidated financial statements of Martin Marietta, Premier, the operations acquired from QUIKRETE, New Frontier, and Lhoist.

The unaudited pro forma condensed combined statements of earnings (the “pro forma statements of earnings”) for the six months ended June 30, 2026 and for the year ended December 31, 2025, give effect to the Other Acquisitions, the Transaction and the related financings as if they were consummated on January 1, 2025. The unaudited pro forma condensed combined balance sheet (the “pro forma balance sheet”) as of June 30, 2026, gives effect to the Transaction and the related financings as if it was consummated on June 30, 2026. Assumptions and estimates underlying the pro forma adjustments are described in the accompanying notes, which should be read in connection with the pro forma financial statements.

In accordance with Accounting Standards Codification (ASC) Topic 805, Business Combinations, the Transaction is being accounted for under the acquisition method with Martin Marietta as the acquirer. The purchase price has been allocated to the preliminary estimated fair values of the assets acquired and liabilities assumed from Lhoist using fair value concepts defined in ASC Topic 820, Fair Value Measurement. Fair value is defined as the price that would be received to sell an asset or paid to transfer

a liability in an orderly transaction between market participants as of the measurement date, which, in this case, is the closing date of the Transaction. The preliminary Transaction consideration and unaudited pro forma adjustments are subject to further adjustments as additional information becomes available and as additional analyses are performed, and such further adjustments may be material.

The pro forma financial statements should be read in conjunction with:

• the accompanying notes to the pro forma financial statements;

• the historical audited consolidated financial statements of Martin Marietta as of and for the year ended December 31, 2025, included in Martin Marietta’s Form 10-K filed with the SEC on February 19, 2026;

• the historical unaudited condensed consolidated interim financial statements of Martin Marietta as of and for the quarter and six months ended June 30, 2026, included in Martin Marietta’s Form 10-Q filed with the SEC on July 30, 2026;

• the historical audited consolidated financial statements of Lhoist as of and for the years ended December 31, 2025 and 2024, included in Exhibit 99.1; and

• the historical unaudited condensed consolidated interim financial statements of Lhoist as of June 30, 2026 and for the six months ended June 30, 2026 and 2025, included in Exhibit 99.2.

The pro forma financial statements have been presented for illustrative purposes only and do not reflect the impact of anticipated synergies expected to be realized from the Transaction and the Other Acquisitions. Therefore, the pro forma financial statements are not indicative of the results of operations and financial position that would have been achieved had the pro forma events taken place on the dates indicated, or the future consolidated results of operations or financial position of the combined company. The following information is only for the limited purpose of presenting what the results of operations and financial position of the combined businesses of Martin Marietta, Premier, operations acquired from QUIKRETE, New Frontier, and Lhoist might have looked like had the Other Acquisitions and the Transaction taken place at an earlier date and should not be relied on for any other purpose. All financial data included in the pro forma financial statements is presented in millions of U.S. Dollars and has been prepared on the basis of U.S. GAAP and Martin Marietta’s presentation and accounting policies.

NOTES TO THE UNAUDITED PRO FORMA CONDENSED COMBINED

FINANCIAL STATEMENTS

Note 1. Basis of Pro Forma Presentation

The pro forma financial statements have been derived from the historical consolidated financial statements of Martin Marietta, Premier, the operations acquired from QUIKRETE, New Frontier, and Lhoist. The pro forma statements of earnings for the six months ended June 30, 2026 and for the year ended December 31, 2025, give effect to the Other Acquisitions, the Transaction and the related financings as if they were consummated on January 1, 2025. The pro forma balance sheet as of June 30, 2026, gives effect to the Transaction and the related financings as if they were consummated on June 30, 2026. The pro forma financial statements and related notes are prepared in accordance with Article 11 of Regulation S-X, as amended.

In accordance with Accounting Standards Codification (ASC) Topic 805, Business Combinations, the Transaction is being accounted for under the acquisition method with Martin Marietta as the acquirer. The purchase price has been allocated to the preliminary estimated fair values of the assets acquired and liabilities assumed from Lhoist using fair value concepts defined in ASC Topic 820, Fair Value Measurement. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date, which, in this case, is the closing date of the Transaction. This is an exit price concept for the valuation of the asset or liability. In addition, market participants are assumed to be buyers and sellers in the principal (or the most advantageous) market for the asset or liability. Fair value measurements for an asset assume the highest and best use by these market participants. As a result, the pro forma financial statements may record assets which are not intended to be used by Martin Marietta and/or value assets at fair value measures that do not reflect Martin Marietta’s intended use of those assets. Many fair value measurements can be highly subjective and it is also possible that others applying reasonable judgment to the same facts and circumstances could develop and support a range of alternative estimated amounts. Martin Marietta believes the preliminary estimated fair values are reasonable, based on information that is currently available. A final determination of the fair value of Lhoist’s assets and liabilities will be based on the actual net tangible and intangible assets and liabilities of Lhoist that exist as of the closing date of the Transaction and, therefore, cannot be made prior to the closing of the Transaction. Accordingly, the preliminary Transaction consideration and unaudited pro forma adjustments are subject to further adjustments as additional information becomes available and as additional analyses are performed, and such further adjustments may be material.

The pro forma financial statements do not reflect any anticipated cost savings or associated costs to achieve such savings from operating efficiencies, synergies or other restructuring that result from the Transaction or the Other Acquisitions. In addition, the pro forma financial statements do not purport to project the future financial position or operating results of the combined company. Transactions between Martin Marietta, Premier, QUIKRETE, New Frontier, and Lhoist during the periods presented in the pro forma financial statements have been eliminated as if Premier, QUIKRETE, New Frontier, and Lhoist were consolidated subsidiaries of Martin Marietta during the periods presented.

Note 2. Preliminary Transaction Consideration and Purchase Price Allocation

The preliminary Transaction consideration as of June 30, 2026 is calculated as follows:

Martin Marietta shares to be issued			10,953,543
Martin Marietta share price on June 30, 2026		$	576.70
Preliminary share consideration		$	6,316,908,248
Cash consideration			7,000,000,000
Estimated Other Transaction Cash Consideration			222,000,000
Total preliminary Transaction consideration		$	13,538,908,248

Pursuant to the SSA, Martin Marietta is obligated to pay LNA Holding approximately $1.2 million for each calendar day for the period beginning on January 1, 2026 and ending on the closing date of the Transaction, which, for purposes of these pro forma financial statements, amounts to the estimated other Transaction cash consideration of $222 million, assuming a closing date of June 30, 2026 (the “Estimated Other Transaction Cash Consideration”). The actual amount of the overall Estimated Other Transaction Cash Consideration will depend on the ultimate closing date of the Transaction.

A sensitivity analysis related to the fluctuation in Martin Marietta’s common stock price was performed to assess the impact of a hypothetical change of 10% on Martin Marietta’s closing share price on the estimated purchase consideration. Martin Marietta believes that a 10% fluctuation in the market price of its common stock is reasonably possible based on historical volatility. The following table shows the effect of changes in Martin Marietta’s share price and the resulting impact on the estimated Transaction consideration:

Change in Share Price		Share Price				Estimated Preliminary Transaction Consideration (in millions)
As presented		$	576.70			$	13,539
Increase of 10%		$	634.37			$	14,171
Decrease of 10%		$	519.03			$	12,907

The following is the preliminary estimated allocation of the Transaction consideration to the fair value of the assets acquired and the liabilities assumed by Martin Marietta in the Transaction as of June 30, 2026:

		(in millions)
Assets
Cash and cash equivalents		$	26
Accounts receivable			224
Advances to Lhoist affiliates			279
Inventories			152
Other current assets			57
Property, plant and equipment			3,247
Other intangible assets			5,900
Other noncurrent assets			66
Total Assets, excluding goodwill		$	9,951

8

Liabilities
Accounts payable		$	85
Accrued expenses			72
Current operating lease liabilities			18
Noncurrent operating lease liabilities			50
Other noncurrent liabilities			148
Deferred income taxes			2,039
Total Liabilities		$	2,412
Net assets acquired		$	7,539
Goodwill			6,000
Purchase Price		$	13,539

Goodwill represents the excess of the preliminary estimated Transaction consideration over the estimated fair value of the underlying net assets acquired.

9

QUIKRETE Holdings, Inc.

Martin Marietta completed an asset exchange with QUIKRETE on February 23, 2026. The acquired operations from QUIKRETE included in the pro forma statement of earnings include operations for the year ended December 31, 2025 and for the period from January 1, 2026 to February 23, 2026. The financial results for operations divested by Martin Marietta are reported as discontinued operations and therefore are not included in the historical Martin Marietta statements of earnings for the annual period ended December 31, 2025 and the six-month period ended June 30, 2026 presented in these pro forma financial statements.

(e) Cost of Revenues. Reflects $67 million amortization expense included in the pro forma statement of earnings for the year ended December 31, 2025 for the increase in fair value of acquired inventory from the Martin Marietta historical statement of earnings for the six months ended June 30, 2026. The acquired inventory is expected to be sold within 12 months of the closing date of the acquisition and has been reflected in the pro forma statement of earnings for the year ended December 31, 2025, as this transaction is assumed to have closed on January 1, 2025.

(f) Cost of Revenues. Reflects $26 million and $7 million of additional depreciation, depletion, and amortization expense for the year ended December 31, 2025 and the period January 1, 2026 to February 23, 2026, respectively, related to the write-up of QUIKRETE’s property, plant and equipment to fair value and the recognition of other acquired intangible assets as of the assumed January 1, 2025 closing date of this transaction.

Also reflects accelerating the $16 million expense resulting from the repricing of deferred income tax liabilities from the six months ended June 30, 2026 (recorded on Martin Marietta’s historical income statement) to the year ended December 31, 2025.

New Frontier Materials, LLC

Martin Marietta acquired New Frontier on May 15, 2026. The historical statements of earnings for New Frontier included in the pro forma statement of earnings are for the year ended December 31, 2025 and the period from January 1, 2026 to May 15, 2026.

(j) Cost of Revenues. Reflects the $7 million amortization expense included in the pro forma statement of earnings for the year ended December 31, 2025 for the increase in fair value of acquired inventory. The acquired inventory is expected to be sold within 12 months of the closing date of the New Frontier acquisition and has been reflected in the pro forma statement of earnings for the year ended December 31, 2025, as the transaction is assumed to have closed on January 1, 2025. Of this amount, $4 million of the amortization expense was incurred in 2026 in the Martin Marietta historical statement of earnings and the remaining $3 million will be incurred subsequent to June 30, 2026.

10

(k) Cost of Revenues. Reflects $11 million and $1 million of additional depreciation, depletion, and amortization expense for the year ended December 31, 2025 and the period from January 1, 2026 to May 15, 2026, respectively, related to the write-up of New Frontier’s property, plant and equipment to fair value and the recognition of other acquired intangible assets as of the assumed January 1, 2025 closing date of the transaction.

(n) Reclassification of Lhoist’s historical presentation. Based on the amounts reported in the Martin Marietta consolidated statements of earnings for the six months ended June 30, 2026 and for the year ended December 31, 2025, certain financial statement line items included in Lhoist’s historical presentation have been reclassified to conform to corresponding financial statement line items included in Martin Marietta’s historical financial statement presentation. Royalty income of $7 million and $1 million for the year ended December 31, 2025 and the six months ended June 30, 2026, respectively, has been reclassified to other operating income, net. Interest income of $16 million and $5 million for the year ended December 31, 2025 and the six months ended June 30, 2026, respectively, has been reclassified to other nonoperating (income)/expense, net. These reclassifications had no material impact on the historical earnings from continuing operations reported by Martin Marietta or Lhoist.

(o) Revenues and Cost of Revenues. Reflects the elimination of $4 million and $1 million of transactions between Martin Marietta and Lhoist that occurred for the year ended December 31, 2025 and the six months ended June 30, 2026, respectively, as if Lhoist was a consolidated subsidiary of Martin Marietta during the aforementioned periods. The transactions between the entities were for the purchases/sales of aggregates products.

(p) Cost of Revenues.

11

(r) Acquisition, Divestiture and Integration Expenses. Reflects recording $83 million of estimated transaction expenses in the year ended December 31, 2025, to be incurred by Martin Marietta subsequent to June 30, 2026.

(s) Interest Expense. Reflects the elimination of $55 million and $26 million of Lhoist’s historical interest expense for the year ended December 31, 2025, and the six months ended June 30, 2026, respectively, as Martin Marietta did not assume Lhoist’s historical debt (see Note 4).

(t) Other Nonoperating (Income)/Expense, Net. Reflects the elimination of Lhoist’s $3 million gain related to the interest rate swap derivative that was amortized into earnings during the year ended December 31, 2025. Martin Marietta did not assume Lhoist’s long-term debt nor the related interest rate swap derivative.

(u) Income Tax Expense (Benefit). Reflects the income tax effect of assuming Martin Marietta’s statutory income tax rate of 24.6% for the pro forma adjustments and Lhoist’s historical earnings.

(v) Net Earnings Per Share and Weighted Average Shares Outstanding. The pro forma basic and diluted earnings per share are based on the historical weighted average number of shares of Martin Marietta common stock outstanding, adjusted for the 10,953,543 shares of common stock issued to Lhoist stockholders as part of the purchase consideration in the Transaction. Shares of common stock issued to Lhoist stockholders are assumed to have been issued as of January 1, 2025 and outstanding for the entirety of the annual period ended December 31, 2025 and the six-month period ended June 30, 2026.

The following table presents the computation of pro forma basic and diluted weighted-average shares outstanding for the year ended December 31, 2025.

		Weighted-Average Shares
		(in millions)
Martin Marietta’s historical weighted-average common shares outstanding—basic			60.5
Shares of Martin Marietta’s common stock issued to consummate Transaction			10.9
Pro forma weighted-average common shares outstanding—basic			71.4
Martin Marietta’s historical weighted-average common shares outstanding—diluted			60.6
Shares of Martin Marietta’s common stock issued to consummate Transaction			10.9
Pro forma weighted-average common shares outstanding—diluted			71.5

12

The following table presents the computation of pro forma basic and diluted weighted-average shares outstanding for the six months ended June 30, 2026.

		Weighted-Average Shares Outstanding
		(in millions)
Martin Marietta’s historical weighted-average common shares outstanding—basic			60.2
Shares of Martin Marietta’s common stock issued to consummate Transaction			10.9
Pro forma weighted-average common shares outstanding—basic			71.1
Martin Marietta’s historical weighted-average common shares outstanding—diluted			60.3
Shares of Martin Marietta’s common stock issued to consummate Transaction			10.9
Pro forma weighted-average common shares outstanding—diluted			71.2

(w) Income Tax Expense (Benefit). Reflects the income tax benefit from the additional interest expense based on the statutory income tax rate of 24.6%.

Debt Financing Related to the Transaction and Other Acquisitions

(x) Interest Expense. Reflects the additional interest expense of (i) $18 million for borrowings for the period January 1, 2025 to July 25, 2025, used to consummate the acquisition of Premier, as of the assumed January 1, 2025 closing date; (ii) $41 million and $15 million for borrowings for the year ended December 31, 2025 and the period January 1, 2026 to May 15, 2026, respectively, used to consummate the acquisition of New Frontier, as of the assumed January 1, 2025 closing date; and (iii) $388 million and $194 million for the year ended December 31, 2025, and the six months ended June 30, 2026, respectively, for borrowings used to finance the cash portion of the Transaction consideration as of the assumed January 1, 2025 closing date.

The pro forma financial information reflects interest expense calculated using an assumed weighted average interest rate of 5.47%, which has been determined for illustrative purposes and is not necessarily indicative of the rate that may be obtained upon issuance of debt; such rate is subject to change based on, among other things, prevailing market conditions, and any variation could result in material differences to the pro forma results. Inclusive of estimated borrowings from January 1, 2025 through the earlier of the closing of the respective transaction or June 30, 2026 for each of the Premier, New Frontier, and Lhoist acquisitions, an increase or decrease in the assumed interest rate of 5.47% by one-eighth of a percent would increase or decrease combined pro forma interest expense by $20 million for the year ended December 31, 2025 and $9 million for the six months ended June 30, 2026.

Note 4. Adjustments to Pro Forma Balance Sheet

(a) Reclassified Lhoist historical presentation. Based on the amounts reported in the Martin Marietta consolidated balance sheet as of June 30, 2026, certain financial statement line items included in Lhoist’s historical financial statement presentation have been reclassified to conform to corresponding financial statement line items included in Martin Marietta’s historical presentation. Specifically, (i) $48 million has been reclassified from prepaid expenses and other to other current assets; (ii) $9 million has been reclassified from income taxes receivable to other current assets; (iii) $25 million has been reclassified from accrued expenses to accrued salaries, benefits and payroll taxes; (iv) $5 million has been reclassified from income taxes payable to other current liabilities; and (v) $67 million has been reclassified from accrued expenses to other current liabilities. These reclassifications had no material impact on total assets, total liabilities and total equity historically reported by Martin Marietta or Lhoist.

13

(b) Inventories and Deferred Income Taxes. Reflects the $59 million write-up to record Lhoist’s inventories at fair value. The write-up of inventories resulted in the recognition of a $14 million deferred income tax liability, which was calculated using an estimated statutory rate of 24.6%.

(c) Other Current Assets, Accounts Payable and Retained Earnings. Reflects the accrual of $83 million for additional nonrecurring transaction expenses to be incurred by Martin Marietta subsequent to June 30, 2026 and a $20 million income tax receivable for the related income tax benefit (included in other current assets), which was calculated using an estimated statutory rate of 24.6%. The net amount, $63 million, is presented as a reduction of retained earnings.

(d) Property, Plant and Equipment and Deferred Income Taxes. Reflects a write-up of $2,308 million to record Lhoist’s property, plant and equipment at fair value. The mineral reserves are depleted using the units-of-production method. The depreciable property, plant and equipment has an estimated weighted-average remaining useful life of 20 years. The write-up resulted in the recognition of a $567 million deferred income tax liability, which was calculated using an estimated statutory rate of 24.6%.

(e) Goodwill. Reflects the $107 million elimination of Lhoist’s historical goodwill and recording $6,000 million for the excess of the purchase price paid over the fair value of Lhoist’s identifiable assets acquired and liabilities assumed. The goodwill is not deductible for tax purposes.

(f) Other Intangible Assets and Deferred Income Taxes.

On July 15, 2026, Martin Marietta obtained a three-year unsecured term loan commitment in the aggregate principal amount of $1.5 billion to replace a part of such bridge loan commitment. The pro forma financial statements assume that Martin Marietta obtained an additional $5.5 billion of permanent senior unsecured debt to replace the remaining bridge loan commitments prior to the closing of the Transaction. The pro forma financial statements also assume that Martin Marietta borrowed an additional $222 million under its existing $800 million five-year unsecured revolving facility to fund the Estimated Other Transaction Cash Consideration.
