**EXPLANATORY NOTE**

On April 26, 2024, the United States Securities and Exchange Commission (the "SEC") declared effective the Registration Statement

on Form S-4 (file number 333-278185), as amended (as supplemented by the prospectus filed with the SEC on April 26, 2024, the

"Registration Statement"), of Smurfit WestRock Limited, formerly known as Cepheidway Limited and re-registered as an Irish public

limited company and renamed Smurfit Westrock plc (the "Company" or "Smurfit Westrock"), to register ordinary shares of $0.001

each in the capital of Smurfit Westrock (the "Smurfit Westrock Shares") to be issued to the holders of shares of common stock of

WestRock Company ("WestRock"), pursuant to a transaction agreement dated as of September 12, 2023 (the "Transaction

Agreement"), among Smurfit Westrock, Smurfit Kappa Group plc ("Smurfit Kappa"), WestRock and Sun Merger Sub, LLC ("Merger

Sub") pursuant to which (i) Smurfit Westrock acquired Smurfit Kappa by means of a scheme of arrangement under the Companies Act

2014 of Ireland (as amended) and (ii) Merger Sub merged with and into WestRock, (the "Merger" and, together with the Smurfit

Kappa Share Exchange, the "Combination"). The Combination closed on July 5, 2024. A detailed description of the terms of the

Combination is included in the Registration Statement. Upon the completion of the Combination on July 5, 2024, Smurfit Kappa and

WestRock each became wholly owned subsidiaries of Smurfit Westrock with Smurfit Kappa shareholders owning approximately

50.3% and WestRock shareholders owning approximately 49.7%. Prior to the closing of the Combination, Smurfit Westrock had no

operations other than activities related to its formation and the Combination. Smurfit Kappa was determined to be the accounting

acquirer in the Combination; therefore, the historical Consolidated Financial Statements of Smurfit Kappa for periods prior to the

Combination are presented as the historical financial statements of the Company. Unless otherwise indicated or the context otherwise

requires, references in this Quarterly Report on Form 10-Q to "Smurfit Westrock," the "Company," "our Company," "we," "our," and

"us," and the like terms, refer to the business and operations of Smurfit Kappa and its wholly-owned subsidiaries, which prior to July

5, 2024, did not include WestRock, when referring to the periods prior to the closing of the Combination, and refer to the combined

company (Smurfit Westrock, including, among others, its subsidiaries Smurfit Kappa and WestRock) when referring to the periods

after the Combination.

This Quarterly Report on Form 10-Q is being filed with respect to the interim quarterly period ended June 30, 2025. Accordingly, the

disclosures herein, including the financial statements and related Management's Discussion and Analysis, describe the business,

financial condition, results of operations, liquidity and capital resources of Smurfit Westrock following the Combination, except as

expressly provided herein. For prior periods, the disclosures herein reflect the financials of Smurfit Kappa, except as expressly

provided herein.

**CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS** 

This Quarterly Report on Form 10-Q includes certain "forward-looking statements" (including within the meaning of Section 27A of

the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"))

regarding, among other things, the plans, strategies, outcomes, outlooks and prospects, both business and financial, of Smurfit

Westrock, the expected benefits of the completed Combination of Smurfit Kappa and WestRock Company (including, but not limited

to, synergies as well as our scale, geographic reach and product portfolio, or impact of announced closures), and any other statements

regarding Smurfit Westrock's future expectations, beliefs, plans, objectives, results of operations, financial condition and cash flows,

or future events or performance. Forward-looking and other statements in this Quarterly Report on Form 10-Q may also address the

Company's corporate responsibility progress, plans, and initiatives (including environmental matters), and the inclusion of such

statements is not an indication that these contents are necessarily material to investors or required to be disclosed in our filings with

the SEC. In addition, historical, current, and forward-looking sustainability-related statements may be based on standards for

measuring progress that are still developing, internal controls and processes that continue to evolve, and assumptions that are subject

to change in the future.

Statements that are not historical facts, including statements about the beliefs and expectations of the management of Smurfit

Westrock, are forward-looking statements. Words such as "may", "will", "could", "should", "would", "anticipate", "intend",

"estimate", "project", "plan", "believe", "expect", "target", "prospects", "potential", "commit", "forecasts", "aims", "considered",

"likely", "estimate" and variations of these words and similar future or conditional expressions are intended to identify forward-

looking statements but are not the exclusive means of identifying such statements. While the Company believes these expectations,

assumptions, estimates and projections are reasonable, such forward-looking statements are only predictions and involve known and

unknown risks and uncertainties, many of which are beyond the control of the Company. By their nature, forward-looking statements

involve risk and uncertainty because they relate to events and depend upon future circumstances that may or may not occur.

Important factors that could cause actual results to differ materially from plans, estimates or expectations include: changes in demand

environment; our ability to deliver on our closure plan and associated efforts; our future cash payments associated with these

initiatives; potential future cost savings associated with such initiatives; the amount of charges and the timing of such charges or

actions described herein; potential future impairment charges; accuracy of assumptions associated with the charges; economic,

competitive and market conditions generally, including macroeconomic uncertainty, customer inventory rebalancing, the impact of

inflation and increases in energy, raw materials, shipping, labor and capital equipment costs; geo-economic fragmentation and

protectionism such as tariffs, trade wars or similar governmental actions affecting the flows of goods, services or currency (including

the implementation of tariffs by the U.S. federal government and reciprocal tariffs and other protectionist or retaliatory measures

governments in Europe, Asia, and other countries have taken or may take in response); the impact of public health crises, such as

pandemics and epidemics and any related company or governmental policies and actions to protect the health and safety of individuals

or governmental policies or actions to maintain the functioning of national or global economies and markets; reduced supply of raw

materials, energy and transportation, including from supply chain disruptions and labor shortages; developments related to pricing

cycles and volumes; intense competition; the ability of the Company to successfully recover from a disaster or other business

continuity problem due to a hurricane, flood, earthquake, terrorist attack, war, pandemic, security breach, cyber-attack, power loss,

telecommunications failure or other natural or man-made events, including the ability to function remotely during long-term

disruptions; the Company's ability to respond to changing customer preferences and to protect intellectual property; the amount and

timing of the Company's capital expenditures; risks related to international sales and operations; failures in the Company's quality

control measures and systems resulting in faulty or contaminated products; cybersecurity risks, including threats to the confidentiality,

integrity and availability of data in the Company's systems; works stoppages and other labor disputes; the Company's ability to

establish and maintain effective internal controls over financial reporting in accordance with Sarbanes Oxley Act of 2002, as amended,

and remediate any weaknesses in controls and processes; the Company's ability to retain or hire key personnel; risks related to

sustainability matters, including climate change and scarce resources, as well as the Company's ability to comply with changing

environmental laws and regulations; the Company's ability to successfully implement strategic transformation initiatives; results and

impacts of acquisitions by the Company; the Company's significant levels of indebtedness; the impact of the Combination on the

Company's credit ratings; the potential impairment of assets and goodwill; the availability of sufficient cash to distribute dividends to

the Company's shareholders in line with current expectations; the scope, costs, timing and impact of any restructuring of operations

and corporate and tax structure; evolving legal, regulatory and tax regimes; changes in economic, financial, political and regulatory

conditions in Ireland, the United Kingdom, the United States and elsewhere, and other factors that contribute to uncertainty and

volatility, natural and man-made disasters, civil unrest, geopolitical uncertainty, and conditions that may result from legislative,

regulatory, trade and policy changes associated with the current or subsequent Irish, U.S. or UK administrations; loss contingencies or

legal proceedings instituted, threatened, future or pending against the Company, including with respect to antitrust related matters;

actions by third parties, including government agencies; the Company's ability to promptly and effectively integrate Smurfit Kappa's

and WestRock's businesses; the Company's ability to achieve the synergies and value creation contemplated by the Combination; the

Company's ability to meet expectations regarding the accounting and tax treatments of the Combination, including the risk that the

Internal Revenue Service may assert that the Company should be treated as a U.S. corporation or be subject to certain unfavorable

U.S. federal income tax rules under Section 7874 of the Internal Revenue Code of 1986, as amended, as a result of the Combination;

other factors such as future market conditions, currency fluctuations, the behavior of other market participants, the actions of

regulators and other factors such as changes in the political, social and regulatory framework in which the Company's group operates

or in economic or technological trends or conditions, and other risks set forth under the heading "Risk Factors" in Part I, Item 1A. in

the 2024 Form 10-K, and as may be updated in this and other subsequent Quarterly Reports on Form 10-Q.

The Company's forward-looking statements speak only as of the date of this Quarterly Report on Form 10-Q or as of the date they are

made. Neither the Company nor any of its associates or directors, officers or advisers provides any representation, assurance or

guarantee that the occurrence of the events expressed or implied in any such forward-looking statements will actually occur. You are

cautioned not to place undue reliance on these forward-looking statements. Other than in accordance with its legal or regulatory

obligations (including under the UK Listing Rules, the Disclosure Guidance and Transparency Rules, the UK Market Abuse

Regulation and other applicable regulations), the Company is under no obligation, and the Company expressly disclaims any intention

or obligation, to update or revise publicly any forward-looking statements, whether as a result of new information, future events or

otherwise.

**Smurfit Westrock plc**

**Notes to the Condensed Consolidated Financial Statements (Unaudited)**

*(in millions, except per share data)*

**1. Description of Business and Summary of Significant Accounting Policies**

***1.1. Description of Business***

Unless the context otherwise requires, or unless indicated otherwise, "we", "us", "our", "Smurfit Westrock" and "the Company" refer

to the business of Smurfit Westrock plc, its wholly-owned subsidiaries and its partially-owned consolidated subsidiaries.

Smurfit Westrock plc is a company limited by shares that is incorporated in Ireland. We are a multinational provider of sustainable

fiber-based paper and packaging solutions. We partner with our customers to provide differentiated, sustainable paper and packaging

solutions that enhance our customers' prospects of success in their markets. Our team members support customers around the world

from our operating and business locations in North America, South America, Europe, Asia, Africa, and Australia.

***1.2. Basis of Presentation***

We derived the Condensed Consolidated Balance Sheet at December 31, 2024from the audited consolidated financial statements

included in the Company's Annual Report on Form 10-K for the year ended December 31, 2024 (the "2024 Consolidated Financial

Statements"). In the opinion of management, all normal recurring adjustments necessary for a fair statement of the Condensed

Consolidated Financial Statements have been included for the interim periods reported.

The accompanying Unaudited Condensed Consolidated Financial Statements have been prepared in accordance with accounting

principles generally accepted in the U.S. ("GAAP") for interim financial information and with Article 10 of Regulation S-X of the

Securities and Exchange Commission ("SEC"). Accordingly, they omit certain notes and other information from the 2024

Consolidated Financial Statements. Therefore, these Condensed Consolidated Financial Statements should be read in conjunction with

the 2024 Consolidated Financial Statements. The results for the three and six months ended June 30, 2025 are not necessarily

indicative of results that may be expected for the full year.

The preparation of the Condensed Consolidated Financial Statements in conformity with U.S. GAAP requires management to make

certain estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the Condensed Consolidated

Financial Statements, disclosures about gain contingencies and contingent liabilities and the reported amounts of revenues and

expenses, including income taxes during the reporting period. Such estimates include the fair value of assets acquired and assumed

liabilities in a business combination, determining goodwill and measuring impairment, income taxes and pension and other

postretirement benefits. These estimates and assumptions are based on management's judgment. Actual results may differ from those

estimates, and the differences could be material.

We base our estimates on the current information available, our experiences and various other assumptions believed to be reasonable

under the circumstances. The process of determining significant estimates is fact specific and takes into account factors such as

historical experience, current and expected economic conditions, product mix, and in some cases, actuarial techniques. We regularly

evaluate these significant factors and make adjustments in the Condensed Consolidated Financial Statements where facts and

circumstances dictate.

Due to rounding, numbers presented throughout this document may not add up precisely to the totals provided and percentages may

not precisely reflect the absolute figures.

**1. Description of Business and Summary of Significant Accounting Policies - continued**

***1.3. Supplier Finance Program Obligations***

We maintain supplier finance programs whereby we have entered into payment processing agreements with certain financial

institutions. These agreements allow participating suppliers to track payment obligations from Smurfit Westrock, and if voluntarily

elected by the supplier, to sell payment obligations from Smurfit Westrock to financial institutions at a discounted price. We are not a

party to the agreements between the participating financial institutions and the suppliers in connection with the program, and we do

not reimburse suppliers for any costs they incur for participation in the program. We have not pledged any assets as security or

provided any guarantees as part of the programs. We have no economic interest in our suppliers' decisions to participate in the

programs. Our responsibility is limited to making payment in full to the respective financial institution according to the terms

originally negotiated with the supplier, which generally do not exceed 120 days. Smurfit Westrock or the financial institutions may

terminate the agreements upon 30 or 90 days' notice. These obligations are classified as accounts payable within the Condensed

Consolidated Balance Sheets.

The outstanding payment obligations to financial institutions under these programs were $375 million and $450 million as of June 30,

2025 and December 31, 2024, respectively.

***1.4. Significant Accounting Policies***

There have been no changes to the Company's significant accounting policies as described in "Note 1. Description of Business and

Summary of Significant Accounting Policies" in the 2024 Consolidated Financial Statements, other than as noted below.

***1.5. Impairment and Restructuring Costs***

When we close a facility, if necessary, we recognize a write-down to reduce the carrying value of related property, plant and

equipment and lease right-of-use ("ROU") assets to their fair value and record charges for severance and other employee-related costs.

For termination costs associated with employees covered by a written or substantive plan, a liability is recorded when it is probable

that employees will be entitled to benefits and the amount can be reasonably estimated. For termination costs associated with

employees not covered by a written and broadly communicated policy covering involuntary termination benefits (severance plan), a

liability is recorded for costs to terminate employees (one-time termination benefits) when the termination plan has been approved and

committed to by management, the employees to be terminated have been identified, the termination plan benefit terms are

communicated, the employees identified in the plan have been notified and actions required to complete the plan indicate that it is

unlikely that significant changes to the plan will be made or that the plan will be withdrawn. The timing and amount of an accrual is

dependent upon the type of benefits granted, the timing of communication and other provisions that may be provided in the benefit

plan.

If property, plant and equipment become impaired as a result of the Company's restructuring efforts, these assets are written down to

their fair value less costs to sell, as the Company commits to dispose of them, and they are no longer in use. Depreciation is

accelerated on property, plant and equipment for the period of time the asset continues to be used until the asset ceases to be used.

For facility closures, we also generally expect to record costs for equipment and inventory relocation, facility carrying costs and costs

to terminate a lease or contract before the end of its term.

Identifying and calculating the cost to exit operations requires certain assumptions to be made, the most significant of which are

anticipated future liabilities, including severance costs, contractual obligations, and the adjustments of property, plant and equipment

and lease ROU assets to their fair value. Our estimates are reasonable, considering our knowledge of the industry we operate in,

previous experience in exiting activities and valuations we may obtain from independent third parties.

***1.6. New Accounting Standards Recently Adopted***

During the six months endedJune 30, 2025, there were no newly issued or newly applicable accounting pronouncements adopted that

had, or are expected to have, a material impact on the Condensed Consolidated Financial Statements.

***1.7. New Accounting Standards Not Yet Adopted***

In December 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures." This

ASU requires the annual financial statements to include consistent categories and greater disaggregation of information in the rate

reconciliation, and income taxes paid disaggregated by jurisdiction. ASU 2023-09 is effective for the Company's annual reporting

periods beginning after December 15, 2024. Adoption is either with a prospective method or a retrospective method of transition.

Early adoption is permitted. The new disclosures (as required) will be included in the consolidated financial statements included in the

Company's Annual Report on Form 10-K for the year ended December 31, 2025.

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" ("ASU 2024-03"). This ASU requires new financial

statement disclosures disaggregating prescribed expense categories within relevant income statement expense captions. ASU 2024-03

will be effective for fiscal years beginning after December 15, 2026, and interim periods beginning after December 15, 2027.

Adoption is either with a prospective method or a retrospective method of transition. Early adoption is permitted. The Company is

currently evaluating the impact of this standard on its disclosures in the consolidated financial statements.

**2. Acquisitions**

***Transaction agreement with WestRock Company***

Pursuant to a transaction agreement dated as of September 12, 2023 (the "Transaction Agreement"), among Smurfit Westrock, Smurfit

Kappa Group plc ("Smurfit Kappa"), WestRock Company ("WestRock") and Sun Merger Sub, LLC ("Merger Sub") the following

was completed (i) Smurfit Westrock acquired Smurfit Kappa by means of a scheme of arrangement under the Companies Act 2014 of

Ireland (as amended) (the "Smurfit Kappa Share Exchange") and (ii) Merger Sub merged with and into WestRock, with WestRock

continuing as the surviving entity (the "Merger" and, together with the Smurfit Kappa Share Exchange, the "Combination"). The

Combination closed on July 5, 2024 (the "Closing Date"). The aggregate merger consideration was $13,461 million.

The purchase price allocation for the Merger is preliminary and is subject to revision as additional information about the acquisition-

date fair value of assets and liabilities becomes available. The allocation of the purchase price with respect to the Merger is based upon

management's estimates of and assumptions related to the fair values of WestRock assets acquired and liabilities assumed as of the

Closing Date. In the period since the 2024 Consolidated Financial Statements, the preliminary purchase price allocation to the fair

value of the assets acquired and liabilities assumed has changed resulting in an increase in the related goodwill of $51 million. The

Company has reflected the measurement period adjustments to date in the period in which the adjustments were identified, and will

continue to reflect measurement period adjustments, if any, in the period in which the adjustments are identified. The Company will

finalize the accounting for the Merger within the measurement period (a period not to exceed 12 months from the Closing Date).

*Unaudited Pro Forma Combined Financial Information* 

The following unaudited pro forma combined financial information presents the combined results of operations for the three and six

months endedJune 30, 2024, as if the Merger had occurred on January 1, 2023.

---

| | | |
|:---|:---|:---|
|  | **Three months ended**<br>**June 30, 2024** | **Six months ended**<br>**June 30, 2024** |
| Net sales | $7786 | $15450 |
| Net income attributable to common shareholders | 267 | 482 |

---

The unaudited pro forma combined financial information above is based on the historical financial statements of Smurfit Kappa,

WestRock, and Smurfit Westrock, and is not indicative of the results of operations that would have been achieved if the Merger had

occurred on January 1, 2023, nor is it indicative of future results. The unaudited pro forma combined financial information has been

prepared by applying the accounting policies of Smurfit Westrock and includes, where applicable, adjustments for the following

factually supportable items or transactions, directly attributable to the Merger: (i) elimination of intercompany activity; (ii)

incremental depreciation expense from the preliminary fair value adjustments to property, plant and equipment; (iii) amortization

expense from the preliminary fair value adjustments to acquired intangible assets; (iv) incremental stock-based compensation expense

associated with the Merger; (v) interest expense for acquisition financing and the amortization of the fair value adjustment to debt

assumed; (vi) removal of pension and other postretirement amortization expense resulting from the fair value adjustment to acquired

WestRock pension and other post-employment benefit assets and liabilities; (vii) changes to align accounting policies; and (viii)

associated tax-related impacts of adjustments.

The unaudited pro forma combined financial information also reflects a pro forma adjustment to remove $58 millionand $113 million

of non-recurring transaction-related costs recorded during the three and six months endedJune 30, 2024 of both Smurfit Kappa and

Westrock directly attributable to the Merger and to reflect these in 2023, as if the Merger had occurred on January 1, 2023.

These pro forma adjustments are based on available information as of the date hereof and upon assumptions that the Company

believes are reasonable to reflect the impact of the Merger on the Company's historical financial information on a supplemental pro

forma basis. Adjustments do not include costs related to integration activities, cost savings or synergies that have been or may be

achieved by the combined business.

For more details related to the transaction with WestRock, refer to "Note 2. Acquisitions" of the 2024 Consolidated Financial

Statements.

**3. Segment Information**

We report our financial results of operations in the following three reportable segments:

i.North America, which includes operations in the U.S., Canada and Mexico.

ii.Europe, the Middle East and Africa ("MEA") and Asia-Pacific ("APAC").

iii.Latin America ("LATAM"), which includes operations in Central America and the Caribbean, Argentina, Brazil, Chile, Colombia,

Ecuador and Peru.

Segment profitability is measured based on Adjusted EBITDA, defined as income before income taxes, unallocated corporate costs,

depreciation, depletion and amortization, interest expense, net, pension and other postretirement non-service income (expense), net,

share-based compensation expense, other (expense) income, net,amortization of fair value step up on inventory, transaction and

integration-related expenses associated with the Combination, impairment and restructuring costsand other specific items that

management believes are not indicative of the ongoing operating results of the business.

The chief operating decision maker ("CODM") uses Adjusted EBITDA for each segment predominantly: to forecast and assess the

performance of the segments, individually and comparatively; to set pricing strategies for the segments; and to make decisions about

the allocation of operating and capital resources to each segment strategically, in the annual budget and in the quarterly forecasting

process. The CODM considers budget, or forecast, -to-actual variances on a quarterly and annual basis for segment Adjusted EBITDA

to inform these decisions.

Significant segment expenses are segment cost of sales and segment selling, general and administrative expenses. Segment cost of

sales primarily includes raw materials, direct labor and plant overhead costs. Segment selling, general and administrative expenses

primarily include compensation and benefits, external professional fees and other operating costs. Both segment cost of sales and

segment selling, general and administrative expenses exclude certain adjustments that management believes are not indicative of the

operating results of the business.

Packaging revenue is derived mainly from the sale of corrugated and consumer packaging products. The remainder of packaging

revenue is composed of bag-in-box, packaging solutions and other paper-based packaging products.

Contract assets relate to the manufacture of certain products that have no alternative use to us, with right to payment for performance

completed to date on these products, including a reasonable profit. Contract assets are reduced when the customer takes title to the

goods and assumes the risks and rewards for the goods. Contract liabilities represent obligations to transfer goods or services to a

customer for which we have received consideration and are reduced once control of the goods is transferred to the customer.

Contract assets and contract liabilities are reported within "Other current assets" and "Other current liabilities", respectively, on the

Condensed Consolidated Balance Sheets.

| Impairment of other assets | 17 |  | 17 |  |
| **Impairment charges** | **$184** | **$—** | **$184** | **$—** |

---

These impairment charges are recognized in the Condensed Consolidated Statements of Operations caption "Impairment and

restructuring costs".

Of the total impairment charges, $176 million of these were triggered by the announcement on April 30, 2025, whereby the Company

announced it would permanently close the Company's coated recycled board mill in St. Paul, Minnesota, U.S., discontinue production

at its containerboard mill in Forney, Texas, U.S. (the "Mill Closures") and had initiated consultations with local works councils in

Germany with a view to permanently closing two converting facilities there (together with the Mill Closures, the "April 2025

Announced Closures"). These mills in the U.S. had ceased production by June 30, 2025.

Following our decision to permanently close the above facilities, the Company assessed the recoverability of the associated long-lived

assets being property, plant and equipment in accordance with ASC 360, "Property, Plant, and Equipment."

The fair value of the property, plant and equipment assets was determined based on their estimated selling price in an orderly

transaction between market participants at the measurement date.

As a result of this assessment, an impairment charge of $159 million was recognized for the property, plant and equipment of the

facilities affected by the April 2025 announcement. An impairment charge of $17 million was recognized in relation to spare parts

included in inventories in these facilities.

**Restructuring Costs**

The segmental split of the restructuring costs of $96 million for the three months ended June 30, 2025shown in the table above is as

follows:

• $43 million was recognized in the North America segment

• $50 million was recognized in the Europe, MEA and APAC segment

• $3 million was recognized in the LATAM segment.

The segmental split of the restructuring costs of $111 million for the six months endedJune 30, 2025 shown in the table above is as

follows:

• $54 million was recognized in the North America segment

Closures. The Company expects to recognize future additional charges of $45 million associated with the April 2025 Announced

Closures through 2026. These restructuring costs are recorded in "Other current liabilities" in the Condensed Consolidated Balance

Sheets. The majority of these charges will be paid within 12 months of the reporting date.

The remaining restructuring costs relate to individual restructuring actions which are individually and cumulatively immaterial.

**11. Fair Value Measurement**

The carrying values, net of deferred debt issuance costs, and estimated fair values of debt with fixed interest rates (classified as Level

2 in the fair value hierarchy) were as follows:

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | **June 30, 2025** | **June 30, 2025** | **December 31, 2024** | **December 31, 2024** |
|  | **Book Value** | **Fair Value** | **Book Value** | **Fair Value** |
| **Debt with fixed interest rates** | **$11775** | **$11783** | **$11370** | **$11289** |

---

The fair value of the Company's debt with fixed interest rates is based on quoted market prices. With the exception of debt with fixed

interest rates, the carrying amounts of all other debt instruments approximate their fair values. The variable nature and repricing dates

of the receivables securitization facilities and the revolving credit facility result in their carrying values approximating their fair

values. Both the revolving credit facility and the receivables securitization facilities are classified as Level 2 in the fair value

hierarchy.

**11. Fair Value Measurement - continued**

**Assets and Liabilities Measured and Recorded at Fair Value on a Recurring Basis**

The Companymeasures and records certain assets and liabilities, including derivative instruments at fair value. The following table

summarizes the fair value of these instruments, which are measured at fair value on a recurring basis, by level, within the fair value

hierarchy:

| **Liabilities measured at fair value** | **$—** | **$—** | **$21** | **$14** |

---

There were no assets or liabilities, which are measured at fair value on a recurring basis, classified as Level 3 in the fair value

hierarchy for the periods presented.

The fair value of listed financial assets is determined by reference to their bid price at the reporting date. Unlisted financial assets are

valued using recognized valuation techniques for the underlying security including discounted cash flows and similar unlisted equity

valuation models.

The fair value of foreign currency forwards, cross currency swaps and energy hedging contracts is based on their listed market price, if

available. If a listed market price is not available, then fair value is estimated by discounting the difference between the contractual

forward price and the current forward price for the residual maturity of the contract using a risk-free interest rate (based on

government bonds).

The fair value of natural gas commodity derivatives is estimated based on observable inputs such as commodity futureprices.

We have financial instruments related to supplemental retirement savings plans ("Supplemental Plans") that are recognized at fair

value. These Supplemental Plans are nonqualified deferred compensation plans where participants' accounts are credited with

investment gains and losses in accordance with their investment election or elections. The investment alternatives under the

Supplemental Plans are generally similar to investment alternatives available under 401(k) plans. Assets and liabilities held in respect

of these Supplemental Plans were carried at$203 million and $171 million, respectively, as of June 30, 2025 (December 31, 2024:

$185 million and $168 million, respectively).

**11. Fair Value Measurement - continued**

**Assets and Liabilities Measured and Recorded at Fair Value on a Non-recurring Basis**

In addition to assets and liabilities that are recorded at fair value on a recurring basis, the Company records certain assets and liabilities

at fair value on a non-recurring basis. This includes assets acquired and liabilities assumed as a result of business combinations or non-

monetary exchanges, situations where events or changes in circumstances indicate the carrying value may not be recoverable

(including restructuring efforts), or when they are deemed to be other than temporarily impaired. These assets include property, plant

and equipment, goodwill and other intangible assets, assets and disposal groups held for sale and other non-current assets. The fair

values of these assets are determined, when applicable, based on valuation techniques using the best information available, and may

include quoted market prices, observable price for similar assets, market comparables, and discounted cash flow projections. These

non-recurring fair value measurements are considered to be Level 3 in the fair value hierarchy.

For more details on the measurement of assets acquired and liabilities assumed as part of business combinations affecting the period

balances, refer to "Note 2. Acquisitions".

Receivables sold under these accounts receivable monetization agreements as of the balance sheet date were approximately

$713 million.

Cash proceeds or payments related to the receivables sold are included in "Net cash provided by operating activities" in the Condensed

Consolidated Statements of Cash Flows in the "Accounts receivable" line item. The expense related to the sale of receivables was $10

million and $20 million for the three and six months endedJune 30, 2025, respectively. The expense recorded may vary depending on

current rates and levels of receivables sold and is recorded in "Other (expense) income, net" in the Condensed Consolidated

Statements of Operations. Although the sales are made without recourse, we maintain continuing involvement with the receivables

sold as we provide collections services related to the transferred assets. The associated servicing liability is not material given the high

credit quality of the customers underlying the receivables and the anticipated short collection period.

For the terms attached to the senior notes, the revolving credit facility, the term loans and the commercial paper programs, refer to the

narrative included in "Note 14. Debt" of the 2024 Consolidated Financial Statements. The carrying amount of borrowings which are

designated as net investment hedges, as outlined therein, has not changed materially and no ineffectiveness was recognized in the

period.

The revolving credit facility had an original term of five years, with twoone-year extension options. In June 2025, the Group

exercised the first extension option, extending the maturity date to June 28, 2030.

At June 30, 2025, all of our debt was unsecured with the exception of our receivables securitization facilities and finance lease

obligations.

**Senior Notes Issued and Redeemed**

There were no new issuances or redemptions during the period in relation to the senior notes.

On April 3, 2025, the Company and certain of its direct and indirect wholly owned subsidiaries (the "Obligor Group") filed with the

SEC a registration statement on Form S-4, with respect to concurrent offers to exchange up to $2,750 million principal amount of

unregistered senior unsecured notes previously issued by Smurfit Kappa Treasury Unlimited Company on April 3, 2024 and

guaranteed by other members of the Obligor Group (see "Note 2. Acquisitions" of the 2024 Consolidated Financial Statements) and

up to $850 million principal amount of unregistered senior unsecured notes previously issued by Smurfit Westrock Financing

Designated Activity Company on November 26, 2024 and guaranteed bythe other members of the Obligor Group (collectively, the

"Original Notes"), in each case for registered notes of equal principal amount issued by the same obligors with the same interest and

maturity dates and coupons and guaranteed by the same members of the Obligor Group (the "New Notes"). The Form S-4 became

effective on April 23, 2025 and the exchange offers commenced on that same date. The terms of the New Notes are identical in all

material respects to the Original Notes except that the New Notes do not have any transfer restrictions, registration rights or additional

interest provisions. The exchange offers expired at 5:00 p.m. New York City time, on May 21, 2025 (the "Expiration Date") and

resulted in approximately $3,588 million aggregate principal amount of the Original Notes (99.66% of the original principal amount)

being validly tendered and not validly withdrawn, for exchange for the New Notes. The Obligor Group accepted all of the Original

Notes which were validly tendered and not validly withdrawn as of the Expiration Date and has issued a like principal amount of New

Notes in exchange for such Original Notes. No new proceeds were received by the Obligor Group in connection with the exchange

offer.

**Receivables Securitization Facilities**

We have three trade receivables securitization programs. The first program has a facility size of €100 million and is scheduled to

mature in December 2029. The second program has a facility size of €230 million and is scheduled to mature in December 2029. The

third program has a facility size of$700 million and is scheduledto mature in June 2027. We have continuing involvement with the

underlying receivables as we provide credit and collection services pursuant to the underlying agreements. For the terms attached to

these programs, refer to the narrative included in "Note 14. Debt" of the 2024 Consolidated Financial Statements.

As of June 30, 2025, the gross amount of receivables collateralizing the €100 million 2029 trade receivables securitization program

was €333 million (December 31, 2024: €318 million). As of June 30, 2025, the facility was fully utilized(December 31, 2024:

$104 million maximum available borrowings, excluding amounts utilized under this facility).

As of June 30, 2025, the gross amount of receivables collateralizing the €230 million 2029 trade receivables securitization program

was €428 million (December 31, 2024: €421 million). As ofJune 30, 2025, maximum available borrowings, excluding amounts

utilized, were $94 million (December 31, 2024: $234 million).

As of June 30, 2025, the gross amount of receivables collateralizing the maximum available borrowings of the $700 million 2027

program was $1,117 million (December 31, 2024: $1,077 million). As ofJune 30, 2025, maximum available borrowings were $700

million (December 31, 2024: $676 million). As of June 30, 2025, amounts available for borrowing under this facility (excluding

amounts utilized), were $150 million (December 31, 2024: $241 million).

**13. Income Taxes**

The effective tax rate for the three and six months endedJune 30, 2025 was144.8% and20.5%,respectively. For the three months

ended June 30, 2025, the effective tax rate was primarily impacted by (i) tax expense associated with an increase in unrecognized tax

benefits of $13 million, (ii) losses during the period that have not been recognized due to uncertainty regarding their future realization,

and (iii) certain non-deductible expenses and other non-recurring items.

**Notes to the Condensed Consolidated Financial Statements (Unaudited)**

*(in millions, except per share data)*

**13. Income Taxes - continued**

For the six months endedJune 30, 2025, the effective tax rate was primarily impacted by (i) the tax benefit associated with the

resolution of $72 million of unrecognized tax benefits (due to the lapse of the statute of limitations), along with the release of $24

millionof accrued interest and penalties associated with the unrecognized tax benefits, (ii) tax expense associated with an increase in

unrecognized tax benefits of $13 million, (iii) losses during the period that have not been recognized due to uncertainty regarding their

future realization, (iv) the geographical mix of where earnings are generated, and (v) certain non-deductible expenses and other non-

recurring items.

The effective tax rate for the three and six months endedJune 30, 2024 was 29.4% and28.9%, respectively. The effective tax rates

were impacted by (i) the geographical mix of income in jurisdictions subject to tax at different tax rates, (ii) the tax effects of

transaction expenses associated with the Combination, which were generally not deductible for tax, partially offset by (iii) non-

recurring income not subject to tax, (iv) a reduction in tax on unremitted foreign earnings, and (v) other non-recurring items.

During the six months endedJune 30, 2025 and June 30, 2024, cash paid for income taxes, net of refunds, was$210 million and $79

million, respectively.

On July 4, 2025, U.S. tax legislation was enacted that included a broad range of tax reform provisions affecting businesses, including

extending and modifying certain existing international and domestic provisions. The Company is currently evaluating the impact of

the new legislation but does not expect it will have a material impact on its results of operations.

**Multiemployer Plans**

As a result of the acquisition of WestRock, we participate in several multiemployer pension plans ("MEPP" or "MEPPs") that provide

retirement benefits to certain union employees in accordance with various collective bargaining agreements and WestRock has

participated in other MEPPs in the past. The multiemployer plan expense was immaterial for the three and six months endedJune 30,

2025. In the normal course of business, we evaluate our potential exposure to MEPPs, including potential withdrawal liabilities.

At June 30, 2025, we had recorded withdrawal liabilities of $128 million (December 31, 2024: $131 million).

**15. Earnings Per Share**

---

Diluted earnings per share is calculated by adjusting the weighted average number of ordinary shares outstanding to assume

conversion of all dilutive potential ordinary shares. These comprise restricted stock units, performance stock units and performance

shares issued under the Company's long-term incentive plans.

**16. Commitments and Contingencies**

**Brazil Tax Liability**

Our subsidiary, WestRock, is challenging claims by the Brazil Federal Revenue Department that we underpaid taxes as a result of

amortization of goodwill generated by the 2002 merger of two of its Brazilian subsidiaries. The matter has proceeded through the

Brazil Administrative Council of Tax Appeals ("CARF") principally in twoproceedings, covering tax years 2003 to 2008 and 2009 to

2012. WestRock was assessed additional taxes, penalties, and interest in both CARF proceedings. In the proceeding for the tax years

2003 to 2008, WestRock was also assessed penalties and interest for fraud, but WestRock won the fraud claim in the proceeding for

the tax years 2009 to 2012. WestRock subsequently filed two lawsuits in Brazilian federal courts seeking annulment of the adverse

CARF decisions. In February 2025, the federal court adjudicating the WestRock challenge to CARF's decision against WestRock for

the 2003 and 2008 period issued a ruling in favor of WestRock nullifying the financial assessments in that case. The decision of the

federal court was appealed by the tax authorities.

We assert that we have no liability in these matters. The total amount in dispute in the two cases before CARF and in the annulment

actions relating to the claimed tax deficiency was R$770 million ($142 million) as of June 30, 2025, including various penalties and

interest. Resolution of the tax positions could have a material adverse effect on our cash flows and results of operations or materially

benefit our results of operations in future periods depending upon their ultimate resolution.

**Asbestos-Related Litigation**

We have been named as a defendant in asbestos-related personal injury litigation, primarily in relation to the historical operations of

certain companies that have been acquired by the Company. To date, the costs resulting from the litigation, including settlement costs,

have not been significant. We accrue for the estimated value of pending claims and litigation costs using historical claims information,

as well as the estimated value of future claims based on our historical claims experience. As of June 30, 2025, there were

approximately720such lawsuits. We believe that we have substantial insurance coverage, subject to applicable deductibles and policy

limits, with respect to asbestos claims. We also believe we have valid defenses to these asbestos-related personal injury claims and

intend to continue to contest these matters vigorously. Should the Company's litigation profile change substantially, or if there are

adverse developments in applicable law, it is possible that the Company could incur significantly more costs resolving these cases. We

record asbestos-related insurance recoveries that are deemed probable. In assessing the probability of insurance recovery, we make

judgments concerning insurance coverage that we believe are reasonable and consistent with our historical dealings and our

knowledge of any pertinent solvency issues surrounding the insurers. The Company currently does not expect the resolution of

pending asbestos litigation and proceedings to have a material adverse effect on the Company's results of operations, financial

condition or cash flows. As of June 30, 2025, the Company had estimated liabilities in respect of these matters of $81 million and

estimated insurance recoveries of $50 million.

**Italian Competition Authority Investigation**

In August 2019, the Italian Competition Authority (the "AGCM") notified approximately 30 companies, of which Smurfit Kappa

Italia, a subsidiary of Smurfit Westrock, was one, that an investigation had found the companies to have engaged in anti-competitive

practices, in relation to which the AGCM levied a fine of approximately $138 million on Smurfit Kappa Italia, which was paid in

2021. In October 2019, Smurfit Kappa Italia appealed the AGCM's decision to the First Administrative Court of Appeal (TAR Lazio),

however Smurfit Kappa Italia was later notified that this appeal had been unsuccessful. In September 2021, Smurfit Kappa Italia filed

a further appeal to the Council of State which published its ruling in February 2023. While some grounds of appeal were dismissed,

the Council of State upheld Smurfit Kappa Italia's arguments regarding the quantification of the fine. As a result, the AGCM was

directed to recalculate Smurfit Kappa Italia's fine. On March 7, 2024, the AGCM notified Smurfit Kappa Italia that its fine had been

reduced by approximately $18 million. Smurfit Kappa Italia has appealed the amount of this reduction and a decision on that appeal is

expected later in 2025.

Separate to these proceedings regarding the fine, in May 2023, Smurfit Kappa Italia filed an application with the Council of State for

revocation of the February 2023 ruling to the extent that it failed to consider certain pleas that had been raised by Smurfit Kappa Italia

on appeal. That application was rejected in July 2025.

After publication of the AGCM's August 2019 decision, a number of purchasers of corrugated sheets and boxes initiated litigation

proceedings against Smurfit Kappa companies, alleging that they were harmed by the alleged anti-competitive practices and seeking

damages. In addition, other parties have threatened litigation against Smurfit Westrock seeking damages (either specified or

unspecified). The Company believes it has significant defenses to the damages claims and intends to vigorously defend the current and

any future litigation.

**International Arbitration Against Venezuela**

Smurfit Kappa, which is now a subsidiary of Smurfit Westrock, announced in 2018 that due to the Government of Venezuela's

measures, Smurfit Kappa no longer exercised control over the business of Smurfit Kappa Carton de Venezuela. Smurfit Kappa's

Venezuelan operations were therefore deconsolidated in the third quarter of 2018. Later that year, Smurfit Kappa's wholly owned

subsidiary, Smurfit Holdings BV, filed an international arbitration claim against the Bolivarian Republic of Venezuela before the

World Bank's International Center for Settlement of Investment Disputes ("ICSID") seeking compensation for Venezuela's unlawful

seizure of its Venezuelan business as well as for other arbitrary, inconsistent and disproportionate State measures that destroyed the

value of its investments in Venezuela. Following the exchange of written submissions, an oral hearing was held in September 2022 in

Paris.

On August 28, 2024, upon the completion of its deliberations, the arbitral tribunal issued an award granting Smurfit Holdings BV,

then a wholly owned subsidiary of Smurfit Westrock, compensation in excess of $469 million, plus legal costs of $5 million, plus

interest from May 31, 2024, until the date of payment (the "Award"). In September 2024,Smurfit Holdings BV initiated proceedings

against the Bolivarian Republic of Venezuela to enforce the Award. In December 2024, the Bolivarian Republic of Venezuela applied

to ICSID to annul the Award. An Annulment Committee has since been formed by ICSID to decide on this application.

**Other Litigation**

We are a defendant in a number of other lawsuits and claims arising out of the conduct of our business. While the ultimate results of

such suits or other proceedings against us cannot be predicted as of the date of this Quarterly Report on Form 10-Q, we believe the

resolution of these other matters will not have a material adverse effect on our results of operations, financial condition or cash flows.

**17. Variable Interest Entities**

***Trade Receivables Securitization Arrangements***

The Company is a party to arrangements involving securitization of its trade receivables. The arrangements required the establishment

of certain special purpose entities namely Smurfit Kappa International Receivables DAC, Smurfit Kappa Receivables plc and Smurfit

Kappa European Packaging DAC (a subsidiary of Smurfit Kappa Receivables plc). The sole purpose of the securitization entities is the

raising of finance for the Company using the receivables generated by certain operating entities, as collateral. All entities are

considered to be Variable Interest Entities ("VIEs").

The Company is the primary beneficiary of Smurfit Kappa International Receivables DAC, Smurfit Kappa European Packaging DAC

and Smurfit Kappa Receivables plc, through various financing arrangements and due to the fact that it is responsible for the entities'

most significant economic activities.

The carrying values of the restricted asset and limited recourse liability as of June 30, 2025($892 million and $294 million,

respectively) and as of December 31, 2024 ($765 million and $5 million, respectively) approximate their fair values due to the short-

term nature of the securitized assets and the floating rates of the liabilities.

***Timber Note Receivable Securitization Arrangement***

The Company is also a party to an arrangement involving securitization of its note receivable. Pursuant to the sale of forestlands in

2007, a special purpose entity ("SPE") namely MeadWestvaco Timber Notes Holding, LLC ("MWV TN") received an installment

note receivable in the amount of $398 million ("Timber Note"). Using this installment note as collateral, the SPE received proceeds

under secured financing agreements, which is recorded as a non-recourse liability.

Using the Timber Note as collateral, MWV TN received $338 million in proceeds under a secured financing agreement with a bank.

Under the terms of the agreement, the liability from this transaction is non-recourse to the Company and is payable from the Timber

Note proceeds upon its maturity in October 2027. As a result, the Timber Note is not available to satisfy any obligations of the

Company. MWV TN can elect to prepay at any time the liability in whole or in part, however, given that the Timber Note is not

prepayable, MWV TN expects to repay the liability at maturity from the Timber Note proceeds.

The Company is the primary beneficiary of MWV TN through various financing arrangements and due to the fact that it is responsible

for the entity's most significant economic activities. This entity is considered to be a VIE.

The carrying values of the restricted asset and non-recourse liability as of June 30, 2025 ($389 million and $334 million, respectively)

and as of December 31, 2024 ($387 million and $333 million, respectively) approximate their fair values due to their floating rates.

The fair values of the restricted assets and non-recourse liabilities are classified as level 2 within the fair value hierarchy.

***Green Power Solutions***

Green Power Solutions of Georgia, LLC ("GPS") is a joint venture providing steam to the Company and electricity to a third party

client. The Company owns a 48% interest in GPS and the majority of the debt issued through the entity SP Fiber Holdings Inc. ("SP

Fiber"), a 100% owned subsidiary. Based on the commercial and financial relationships in force between SP Fiber and GPS, it has

been determined that the SP Fiber has a controlling financial interest in and is the primary beneficiary of GPS. The vehicle held

unrestricted cash of $3 million and $2 millionas of June 30, 2025 and December 31, 2024, respectively.

**19. Subsequent Events**

**Legal Proceedings**

On July 29, 2025, Smurfit Westrock plc, Smurfit Kappa North America LLC, WestRock CP, LLC and seven other industry

participants were named as defendants in a class action lawsuit filed in the U.S. District Court for the Northern District of Illinois

alleging violations of U.S. antitrust laws. The lawsuit alleges violations of Sections 1 and 3 of the Sherman Act, asserting that the

defendants conspired to fix, raise and maintain supracompetitive prices for containerboard sheets, linerboard sheets, and finished

packaging products made from containerboard and/or linerboard in the United States. The complaint seeks damages, including treble

damages under the Clayton Act, pre- and post-judgment interest, injunctive relief and litigation expenses and attorneys' fees. The

Company believes that it has substantial defenses and intends to vigorously defend against the lawsuit. While the Company is

currently unable to determine the ultimate outcome of this matter or estimate the range of potential loss due to the early stage of this

proceeding, it is possible that an adverse outcome could have a material impact on its financial condition, results of operations, or cash

flows.

**Dividend Approval**

On July 30, 2025, the Company announced that its Board approved a quarterly dividend of $0.4308 per share on its ordinary shares.

The quarterly dividend of $0.4308 per ordinary share is payable September 18, 2025 to shareholders of record at the close of business

on August 15, 2025.

**<u>OVERVIEW</u>**

Smurfit Westrock is one of the world's largest integrated manufacturers of paper-based packaging products in terms of volumes and

sales, with operations in North America, South America, Europe, Asia, Africa, and Australia. Smurfit Westrock partners with its

customers to provide differentiated, sustainable paper and packaging solutions that enhance its customers' prospects of success in their

markets. For additional information, see "Part I, Item 1. Business" included in the Company's Annual Report on Form 10-K.

**Transaction Agreement and Combination with WestRock**

As described in "Note 2. Acquisitions" of the Condensed Consolidated Financial Statements, the Combination closed on July 5, 2024.

The consolidated financial statements of Smurfit Westrock following the Smurfit Kappa Share Exchange are a continuation of the

financial statements of Smurfit Kappa and therefore, the historical consolidated financial information for periods prior to the

Combination, including the comparatives presented, reflect the pre-Combination carrying values of Smurfit Kappa except for the

retrospective adjustment to reflect the Company's legal share capital as the successor after giving effect to the Smurfit Kappa Share

Exchange.

Refer to "Note 2. Acquisitions" of the Condensed Consolidated Financial Statements for additional information related to the

accounting for the Combination.

**Recent Developments**

*Capacity Reduction and Facility Closures*

On April 30, 2025, we filed an 8-K that announced our plan to permanently close our coated recycled paperboard ("CRB") mill in St.

Paul, Minnesota, U.S. and discontinue production at our containerboard mill in Forney, Texas, U.S. We stopped production at these

two mills in June 2025 and May 2025, respectively. The mill closures reduced our capacity by over 500,000 tons. The Company has

also initiated consultations with local works councils in Germany with a view to permanently closing two converting facilities there.

The mill closures and two converting facility closures are not expected to have a significant impact on our net sales as we aim to

match our supply with customer demand. See "Note5. Impairment and Restructuring Costs" of the Condensed Consolidated Financial

Statements for additional information. Excluding associated impairment and restructuring costs, the elimination of corresponding fixed

costs is anticipated to increase overall profitability.

**<u>EXECUTIVE SUMMARY</u>**

Smurfit Westrock's net sales increased by $4,971 million, to $7,940 million in the three months endedJune 30, 2025, from $2,969

million in the three months endedJune 30, 2024. Net sales increased by $9,697 million, to $15,596 million in the six months ended

June 30, 2025, from $5,899 million in the six months endedJune 30, 2024. As described in "Results of Operations" below, the

increase in both periods was primarily due to the acquisition of WestRock which contributed $4,839 million in the three months ended

June 30, 2025 and $9,575 million in the six months endedJune 30, 2025.

Net (loss) income attributable to common shareholdersdecreased by $160 million, due to a loss of $28 million in the three months

endedJune 30, 2025, from income of $132 million in the three months endedJune 30, 2024. Net (loss) income attributable to common

shareholdersincreased by $33 million, to income of $356 million in the six months endedJune 30, 2025, from income of $323 million

in the six months endedJune 30, 2024. The decrease in the three months endedJune 30, 2025 was primarily due to impairment and

restructuring costs, and the increase in the six months endedJune 30, 2025, was primarily due to the acquisition of Westrock, with the

positive impact of the Combination partially offset by higher interest expense and higher impairment and restructuring costs. See

"Note 5. Impairment and Restructuring Costs" of the Condensed Consolidated Financial Statements for additional information.

Net cash provided by operating activities increased by $682 million, to $1,064 million in the six months endedJune 30, 2025, from

$382 million in the six months endedJune 30, 2024, primarily due to a $988 million increase in net income adjusted for non-cash

items, including depreciation, depletion and amortization, impairment charges, cash surrender value increase in excess of premiums

paid, share-based compensation expense, deferred income tax benefit, and pension and other postretirement funding more than cost.

The increase in net income adjusted for non-cash items was partially offset by the $306 millionincrease in the cash outflows from

changes in operating assets and liabilities primarily driven by increased accounts receivables including higher selling prices. During

the six months endedJune 30, 2025, Smurfit Westrock invested $999 million in capital expenditures. The Company's net cash inflow

from changes in debt was $318 million, and it paid $450 million of cash dividends to shareholders. See the section entitled "Liquidity

and Capital Resources" below for additional information.

Refer to "Results of Operations" for a detailed review of Smurfit Westrock's performance.

**SIGNIFICANT FACTORS AND TRENDS AFFECTING SMURFIT WESTROCK'S RESULTS**

Smurfit Westrock's operations have been, and will continue to be, affected by many factors, some of which are beyond the Company's

control. Smurfit Westrock's net sales are primarily derived from the sale of containerboard, corrugated containers, paperboard,

consumer packaging, and other paper-based packaging products. As such, Smurfit Westrock's net sales during any period are largely

influenced by volumes, prices and costs of the corrugated containers and consumer packaging products that Smurfit Westrock sells

during that period.

*Volumes*

In general, demand for corrugated containers and consumer packaging is closely correlated with overall economic growth and activity.

It also directionally correlates with levels of industrial production and is impacted by the trends affecting the choice of medium (paper,

plastic, glass, metal, or wood) used in the packaging of these products. As a result, demand is driven by the need for: (i) packaging

products for consumer and industrial goods, (ii) higher value-added corrugated products used for point-of-sale displays and consumer

and shelf-ready packaging, and (iii) packaging of pharmaceutical products and the growth of related industries. Normal patterns of

demand growth can be disrupted by other macroeconomic trends, including inflation, pandemics (such as the COVID-19 pandemic

and related lockdowns), and global economic and geopolitical developments (including tariffs or other trade restrictions), among

others. For instance, current U.S. tariff policies have introduced uncertainty and may negatively impact demand from the Company's

customers and overall volumes.

Consumer patterns also play a significant role in demand for corrugated packaging and consumer packaging. In recent years, shifting

consumer behaviors have accelerated, particularly with the rise of e-commerce and increased awareness of unsustainable packaging

solutions. These trends have, to date, been beneficial for paper-based packaging, which is typically made from renewable, recyclable

materials. Changing demographics can also influence demand trends in the pharmaceutical industry, a major user of consumer

packaging.

*Prices and Costs*

Prices of corrugated containers and consumer packaging are primarily a function of the cyclical nature of Smurfit Westrock's industry,

capacity and competition in the markets it operates in, prevailing raw material prices, and other operating costs, such as energy,

chemicals, and transportation, overlaying supply and demand balances.

As paper costs generally represent a large portion of the cash cost of production for corrugated containers or consumer packaging,

containerboard price movements tend to impact the prices of corrugated containers. In turn, the cost of paper is influenced by

movements in the price of its major raw materials—wood or recycled paper—along with other supply and demand factors. Smurfit

Westrock's production processes are energy-intensive, making production costs also sensitive to the price of energy (primarily gas and

electricity), which have historically been volatile. Other key cost drivers include employee benefit expenses, largely determined by

workforce size, and shipping and handling costs, which are generally affected by fuel prices and overall labor inflation.

While many of Smurfit Westrock's customer contracts include price adjustment clauses that allow cost increases to be passed on to

customers, these clauses may not in all cases be effective to offset rising costs. Additionally, for corrugated and consumer packaging

products, even when Smurfit Westrock is able to implement price increases, there is typically a three- to six-month lag between raw

material price hikes and the realization of higher pricing from customers.

*Foreign Currency Effects*

Smurfit Westrock operates in multiple countries across North America, South America, Europe, Asia, Africa, and Australia. As a

result, currency fluctuations can have both direct and indirect impacts on its financial statements, which are presented in U.S. dollars.

Net sales increased by $4,971 million, to $7,940 million in the three months endedJune 30, 2025, from $2,969 million in the three

months endedJune 30, 2024. This increase was primarily due to the impact of $4,839 millionrelated to the acquisition of WestRock.

Excluding the impact of this acquisition, net sales increased by $132 million primarily resulting from a $122 million net positive

foreign currency impact and a positive impact of $25 million due to a higher selling price mix, partly offset by a negative volume

impact of $15 million.

Net sales increased by $9,697 million, to $15,596 million in the six months endedJune 30, 2025, from $5,899 million in the six

months endedJune 30, 2024. This increase was primarily due to the impact of$9,575 millionrelated to the acquisition of WestRock.

Excluding the impact of this acquisition, net sales increased by $122 million primarily resulting from a $234 million positive impact

due to a higher selling price mix, partly offset by a negative volume impact of $58 million and a $53 million net negative foreign

currency impact.

See "Segment Information" below for more detail on Smurfit Westrock's segment results.

***Cost of Goods Sold***

Cost of goods sold increased by $4,149 million, to $6,425 million in the three months endedJune 30, 2025, from $2,276 million in the

three months endedJune 30, 2024. The increase in cost of goods sold was primarily due to the impact of the acquisition of WestRock

of $4,081 million. Excluding the impact of this acquisition, cost of goods sold increased by $68 million primarily due to net negative

foreign currency movements and higher input prices.

Cost of goods sold increased by $8,008 million, to $12,504 million in the six months endedJune 30, 2025, from $4,496 million in the

six months endedJune 30, 2024. The increase in cost of goods sold was primarily due to the impact of the acquisition of WestRock of

$8,011 million.

***Selling, General and Administrative ("SG&A") Expenses***

SG&A expenses increased by $574 million, to $963 million in the three months endedJune 30, 2025, from $389 million in the three

months endedJune 30, 2024. The increase in SG&A expenses was primarily due to additional SG&A expenses of $541 million related

to the acquisition of WestRock.

SG&A expenses increased by $1,167 million, to $1,936 million in the six months endedJune 30, 2025, from $769 million in the six

months endedJune 30, 2024. The increase in SG&A expenses was primarily due to additional SG&A expenses of $1,096 million

related to the acquisition of WestRock.

***Impairment and Restructuring Costs***

Impairment and restructuring costsincreased by $280 million, to $280 million in the three months endedJune 30, 2025, from $—

million in the three months endedJune 30, 2024. The increase in impairment and restructuring costs was primarily due to our

announced plan to permanently close our CRB mill in St. Paul, Minnesota, U.S., discontinue production at our containerboard mill in

Forney, Texas, U.S. and costs associated with two converting facilities in Germany that are in the process of closing.

Impairment and restructuring costsincreased by $295 million, to $295 million in the six months endedJune 30, 2025, from $—

million in the six months endedJune 30, 2024. Similarly, the increase in impairment and restructuring costs was primarily due to our

announced plan to permanently close our CRB mill in St. Paul, Minnesota, U.S., discontinue production at our containerboard mill in

Forney, Texas, U.S. and costs associated with two converting facilities in Germany that are in the process of closing.

See "Note 5. Impairment and Restructuring Costs" of the Condensed Consolidated Financial Statements for additional information.

***Transaction and Integration-related Expenses Associated with the Combination***

The Company incurred transaction and integration-related expenses associated with the Combination of$21 million and $60 million in

the three months endedJune 30, 2025 and 2024, respectively. In the three months endedJune 30, 2025, transaction and integration-

related expenses consisted primarily of $23 million of integration-related expenses associated with the Combination. In the three

months ended June 30, 2024,transaction and integration-related expenses consisted solely of $60 million of transaction-related

expenses associated with the Combination.

The Company incurred transaction and integration-related expenses associated with the Combination of$57 million and $83 million in

the six months endedJune 30, 2025 and 2024, respectively. In the six months endedJune 30, 2025, transaction and integration-related

expenses consisted solely of integration-related expenses associated with the Combination of $57 million. In the six months ended

June 30, 2024, transaction and integration-related expenses consisted solely of transaction-related expenses associated with the

Combination of $83 million.

Transaction-related costs associated with the Combination were comprised of banking and financing related costs as well as legal and

other professional services which were directly attributable to the Combination and retention payments that were contractually

committed to and associated with the successful completion of the Combination. We incur integration expenses post-acquisition that

reflect work performed to facilitate merger and acquisition integration and primarily consist of professional services and personnel and

related expenses, such as work associated with information systems.

See "Note 6. Transaction and Integration-related Expenses Associated with the Combination" of the Condensed Consolidated

Financial Statements for additional information.

***Pension and Other Postretirement Non-Service Income (Expense), Net***

Pension and other postretirement non-service income (expense), netdecreased by $36 million, to income of $7 million in the three

months endedJune 30, 2025, from expense of $29 million in the three months endedJune 30, 2024. This decrease was primarily due

to an $83 million increase in the expected return on assets primarily due to acquired pension assets in connection with the

Combination and a decrease in net settlement loss of $19 million, partially offset by an increase in interest costs of $68 million

primarily due to acquired pension liabilities in connection with the Combination.

Pension and other postretirement non-service income (expense), netdecreased by $55 million, to income of $16 million in the six

months endedJune 30, 2025, from expense of $39 million in the six months endedJune 30, 2024. This decrease was primarily due to

a $163 million increase in the expected return on assets primarily due to acquired pension assets in connection with the Combination

and a decrease in net settlement loss of $19 million, partially offset by an increase in interest costs of $132 million primarily due to

acquired pension liabilities in connection with the Combination.

***Interest Expense, Net***

Interest expense, net increased by $149 million to $182 million in the three months endedJune 30, 2025, from $33 million in the three

months endedJune 30, 2024. The increase was primarily the result of interest on debt assumed and debt issuedin connection with the

Combination.

Interest expense, net increased by $291 million to $349 million in the six months endedJune 30, 2025, from $58 million in the six

months endedJune 30, 2024. The increase was primarily the result of interest on debt assumed and debt issued in connection with the

Combination.

See "Note 2. Acquisitions" and "Note 14. Debt" of the 2024 Consolidated Financial Statements for additional information on the debt

On July 4, 2025, U.S. tax legislation was enacted that included a broad range of tax reform provisions affecting businesses, including

extending and modifying certain existing international and domestic provisions. The Company is currently evaluating the impact of

the new legislation but does not expect it will have a material impact on its results of operations.

**SEGMENT INFORMATION** 

Smurfit Westrock has identified three operating segments based on how the CODM makes key operating decisions, allocates resources

and assesses the performance of the Company's business. These operating segments are as follows: (i) North America, which includes

operations in the U.S., Canada and Mexico, (ii) Europe, MEA and APAC and (iii) LATAM, which includes operations in Central

America and the Caribbean, Argentina, Brazil, Chile, Colombia, Ecuador and Peru. No operating segments have been aggregated for

disclosure purposes.

Segment results include items directly attributable to a segment as well as those that can be allocated on a reasonable basis, but

exclude certain central costs such as corporate costs, including executive costs, and costs of Smurfit Westrock's legal, company

secretarial, pension administration, tax, treasury and controlling functions and other administrative costs. Segment profitability is

measured based on Adjusted EBITDA, defined as income before income taxes, unallocated corporate costs, depreciation, depletion

and amortization, interest expense, net, pension and other postretirement non-service income (expense), net, share-based compensation

expense, other (expense) income, net,amortization of fair value step up on inventory, transaction and integration-related expenses

associated with the Combination, impairment and restructuring costs and other specific items that management believes are not

indicative of the ongoing operating results of the business.

acquisition of WestRock.

**<u>LIQUIDITY AND CAPITAL RESOURCES</u>**

***Sources and Uses of Cash***

Smurfit Westrock's primary sources of liquidity are the cash flows generated from its operations, its commercial paper program, and

committed credit lines. The uncommitted commercial paper program is supported by the $4,500 million revolving loan facility with a

separate swingline sub-facility which allows for same-day drawing in U.S. dollar. The revolving credit facility had an original term of

five years, with two one year extension options. In June 2025, the Group exercised the first extension option, extending the maturity

date to June 28, 2030. The amount of commercial paper outstanding does not reduce available capacity under the revolving loan

facility. The primary uses of this liquidity are to fund Smurfit Westrock's day-to-day operations, capital expenditures, debt service,

dividends and other investment activity, including acquisitions.

As of June 30, 2025, Smurfit Westrock held cash and cash equivalents of $778 million, of which $334 million were held in euro, $186

million were held in U.S. dollars and $258 million were held in other currencies. At June 30, 2025, the Company had $4,744 million

in undrawn committed facilities available under the revolving loan facility and receivables securitization facilities. The weighted

average period until maturity of undrawn committed facilities was 4.9 years as of June 30, 2025. Combined with cash and cash

equivalents of $778 million, the Company had $5,522 million of available liquidity.

As of June 30, 2025, Smurfit Westrock had $14,425 million of debt, excluding debt issuance costs. As of June 30, 2025, the carrying

amount of current debt was $1,034 million. In the six months endedJune 30, 2025, total debt increased$768 million, $318 million of

which was due to a net increase in borrowings and the remainder was primarily due to translation adjustments. The carrying amount of

the Company's debt includes a fair value adjustment related to debt assumed through mergers and acquisitions. At June 30, 2025, the

unamortized fair value market adjustment was $42 million. Included within the carrying value of Smurfit Westrock's borrowings as of

June 30, 2025 are deferred debt issuance costs of $62 million, of which $8 million is current, all of which will be recognized in interest

expense in Smurfit Westrock's Condensed Consolidated Statements of Operations using the effective interest rate method over the

remaining life of the borrowings. See "Note 12. Debt" of the Condensed Consolidated Financial Statements for a discussion of the

Company's additional debt-related information.

The Company believes that the cash flows generated from its operations, cash on hand, its commercial paper program, available

borrowings under its committed credit lines and available capital through access to capital markets will be adequate to meet the

Company's liquidity and capital requirements, including payments of any declared dividends, for the next 12 months and for the

foreseeable future.

Smurfit Westrock uses a variety of working capital management strategies including supply chain financing ("SCF") programs,

vendor financing and commercial card programs, monetization facilities where we sell short-term receivables to a group of third-party

financial institutions, and receivables securitization facilities. The programs are described below.

The Company engages in certain customer-based SCF programs to accelerate the receipt of payment for outstanding accounts

receivables from certain customers. Certain costs of these programs are borne by the customer or the Company. Receivables

transferred under these customer-based SCF programs generally meet the requirements to be accounted for as sales in accordance with

guidance under "Transfers and Servicing" ("ASC 860"), resulting in derecognition of such receivables from the Company's

Condensed Consolidated Balance Sheets. Receivables involved with these customer-based SCF programs constitute approximately 5%

of the Company's accounts receivable balance at June 30, 2025. In addition, Smurfit Westrock has monetization facilities that sell to

third-party financial institutions all of the short-term receivables generated from certain customer trade accounts. See "Note 11. Fair

Value Measurement" of the Condensed Consolidated Financial Statements for a discussion of the Company's monetization facilities.

Smurfit Westrock's working capital management strategy includes working with its suppliers to revisit terms and conditions, including

the extension of payment terms. The Company's current payment terms with the majority of its suppliers generally range from payable

upon receipt to 120 days and vary for items such as the availability of cash discounts. The Company does not believe its payment

terms will be shortened significantly in the near future, and does not expect its net cash provided by operating activities to be

significantly impacted by additional extensions of payment terms. Certain financial institutions offer voluntary SCF programs that

enable the Company's suppliers, at their sole discretion, to sell their receivables from Smurfit Westrock to the financial institutions on

a non-recourse basis at a rate that leverages the Company's credit rating and thus might be more beneficial to the Company's

suppliers. Smurfit Westrock and its suppliers agree on commercial terms for the goods and services we procure, including prices,

quantities and payment terms, regardless of whether the supplier elects to participate in SCF programs. The suppliers sell Smurfit

Westrock goods or services and issue the associated invoices based on the agreed-upon contractual terms. The due dates of the

invoices are not extended due to the supplier's participation in SCF programs. Smurfit Westrock suppliers, at their sole discretion if

they choose to participate in a SCF program, determine which invoices, if any, they want to sell to the financial institutions. No

guarantees are provided by the Company under SCF programs, and it has no economic interest in a supplier's decision to participate in

the SCF program. Therefore, amounts due to the Company's suppliers that elect to participate in SCF programs are included in the

"Accounts payable" line item in the Company's Condensed Consolidated Balance Sheets and the activity is reflected in "Net cash

provided by operating activities" in the Company's Condensed Consolidated Statements of Cash Flows. Based on correspondence

with the financial institutions that are involved with Smurfit Westrock's two primary SCF programs, while the amount suppliers elect

to sell to the financial institutions varies from period to period, the amount generally averages approximately 11-14% of the

Company's accounts payable balance. The outstanding payment obligations to financial institutions under these programs were $375

million as of June 30, 2025.

Smurfit Westrock also participates in certain vendor financing and commercial card programs to support travel and entertainment

expenses and smaller vendor purchases. Amounts outstanding under these programs are classified as debt primarily because the

Company receives the benefit of extended payment terms and a rebate from the financial institution that would not have otherwise

been received without the financial institution's involvement. Smurfit Westrock also has receivables securitization facilities that allows

for borrowing availability based on underlying accounts receivable eligibility and compliance with certain covenants. See "Note 12.

Debt" and "Note 17. Variable Interest Entities" of the Condensed Consolidated Financial Statements for a discussion of the

receivables securitization facilities and the amount outstanding under the Company's vendor financing and commercial card programs.

***Cash Flow Activity***

The following table contains selected financial information from Smurfit Westrock's Condensed Consolidated Statements of Cash

Flows for the periods presented ($ in millions):

---

| | | |
|:---|:---|:---|
|  | **Six months ended June 30,** | **Six months ended June 30,** |
|  | **2025** | **2024** |
| Net cash provided by operating activities | $1064 | $382 |
| Net cash used for investing activities | $(996) | $(410) |
| Net cash (used for) provided by financing activities | $(204) | $2382 |

---

Net cash provided by operating activities increased by $682 million to $1,064 million in the six months endedJune 30, 2025 from

$382 million in the six months endedJune 30, 2024, primarily due to a $988 million increase in net income adjusted for non-cash

items, including depreciation, depletion and amortization, impairment charges, cash surrender value increase in excess of premiums

paid, share-based compensation expense, deferred income tax benefit, and pension and other postretirement funding more than cost.

The increase in net income adjusted for non-cash items was partially offset by the $306 millionincrease in the cash outflows from

changes in operating assets and liabilities primarily driven by increased accounts receivables including higher selling prices. The

increase in the cash outflows from changes in operating assets and liabilities was inclusive of cash payments to financial institutions of

$12 million in connection with the Company's accounts receivable monetization agreements. See "Note 11. Fair Value Measurement"

of the Condensed Consolidated Financial Statements for additional information.

Net cash used for investing activities of $996 million in the six months endedJune 30, 2025 consisted primarily of capital

expenditures of $999 million. Net cash used for investing activities of $410 million in the six months endedJune 30, 2024 consisted

primarily of capital expenditures of $385 million.

Net cash used for financing activities of $204 million in the six months endedJune 30, 2025 consisted primarily of cash outflows from

cash dividends paid to shareholders of $450 million, tax paid in connection with shares withheld from employees of $67 million and

debt issuance costs of $6 million, partially offset by a net increase in debt of $318 million. Net cash provided by financing activities of

$2,382 million in the six months endedJune 30, 2024 consisted of cash inflows from a net increase in debt of $2,774 million, partially

offset by cash outflows from dividends paid to shareholders of $335 million, debt issuance costs of $29 millionand purchases of

treasury stock of $27 million.

***Contractual Obligations and Commitments***

Smurfit Westrock is a party to enforceable and legally binding contractual obligations involving commitments to make payments to

third parties. These obligations impact Smurfit Westrock's short-term and long-term liquidity and capital resource needs. Certain

contractual obligations are reflected on Smurfit Westrock's Condensed Consolidated Balance Sheets as of June 30, 2025, while others

are considered future obligations. Smurfit Westrock's contractual obligations primarily consist of items such as long-term debt,

including current portion, lease obligations, purchase obligations and other obligations.

There have been no material changes to the contractual obligations and commitments disclosed in "Management's Discussion and

Analysis of Financial Condition and Results of Operations" of the Form 10-K for the fiscal year ended December 31, 2024.

***Off-Balance Sheet Arrangements***

As of June 30, 2025, Smurfit Westrock did not have any off-balance sheet arrangements.

**<u>NON-GAAP FINANCIAL MEASURE</u>**

***Definitions***

***Non-GAAP Financial Measure***

Smurfit Westrock reports its financial results in accordance with generally accepted accounting principles in the U.S. ("GAAP").

However, management believes "Adjusted EBITDA", a non-GAAP financial measure discussed below, provides Smurfit Westrock's

Board of directors, investors, potential investors, securities analysts and others with additional meaningful financial information that

should be considered when assessing its ongoing performance relative to other periods because it adjusts out non-recurring items that

management believes are not indicative of the ongoing results of the business. Smurfit Westrock management also uses this non-

GAAP financial measure in making financial, operating and planning decisions, and in evaluating company performance. Non-GAAP

financial measures are not intended to be considered in isolation of or as a substitute for, or superior to, financial information prepared

and presented in accordance with GAAP and should be viewed in addition to, and not as an alternative for, the GAAP results. The

non-GAAP financial measure Smurfit Westrock presents may differ from similarly captioned measures presented by other companies.

*Adjusted EBITDA*

Smurfit Westrock uses the non-GAAP financial measure "Adjusted EBITDA" to evaluate its overall performance. The composition of

Adjusted EBITDA is not addressed or prescribed by GAAP. Smurfit Westrock defines Adjusted EBITDA as net (loss) incomebefore

income tax expense, depreciation, depletion and amortization, interest expense, net, pension and other postretirement non-service

income (expense), net, share-based compensation expense, other (expense) income, net,amortization of fair value step up on

inventory, transaction and integration-related expenses associated with the Combination, impairment and restructuring costsand other

specific items that management believes are not indicative of the ongoing operating results of the business.

Management believes that the most directly comparable GAAP measure to Adjusted EBITDA is"Net (loss) income".

Set forth below is a reconciliation of the non-GAAP financial measure Adjusted EBITDA to Net (loss) income, the most directly

comparable GAAP measure, for the periods presented ($ in millions).

Smurfit Westrock's management evaluated the effectiveness of the design and operation of its disclosure controls and procedures (as

such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this Quarterly

Report on Form 10-Q. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that

information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is accumulated and

communicated to the Company's management, including its principal executive and principal financial officers, or persons performing

similar functions, as appropriate to allow timely decisions regarding required disclosure. Disclosure controls and procedures are

designed by the Company to ensure that it records, processes, summarizes and reports in a timely manner the information it must

disclose in reports that it files with or submits to the SEC. Anthony Smurfit, President & Group Chief Executive Officer, and Ken

Bowles, Executive Vice President & Group Chief Financial Officer, reviewed and participated in management's evaluation of the

disclosure controls and procedures.

Based on this evaluation, Anthony Smurfit, President & Group Chief Executive Officer, and Ken Bowles, Executive Vice President &

Group Chief Financial Officer concluded that as of the end of the period covered by this Quarterly Report on Form 10-Q, Smurfit

Westrock's disclosure controls and procedures were not effective as a result of the material weakness in our internal control over

financial reporting described below.

**Previously Reported Material Weakness in Internal Control over Financial Reporting**

A material weakness is a control deficiency, or combination of deficiencies, in internal control over financial reporting such that there

is a reasonable possibility that a material misstatement of annual or interim financial statements will not be prevented or detected on a

timely basis.

As discussed elsewhere in this Quarterly Report on Form 10-Q, on July 5, 2024, we completed the Combination between Smurfit

Kappa and WestRock. Prior to the Combination, Smurfit Kappa, as a public limited company incorporated in Ireland and listed on the

London Stock Exchange and on the Euronext Dublin Market, was not subject to Section 404 of the Sarbanes Oxley Act of 2002

("SOX"), while WestRock, as a U.S. publicly traded company incorporated in Delaware and listed on the New York Stock Exchange,

was subject to Section 404 of SOX. Upon the completion of the Combination,Smurfit Kappa and WestRock became wholly-owned

subsidiaries of Smurfit Westrock.

As a result of the Combination, Smurfit Westrock's management is in the process of integrating Smurfit Kappa and WestRock's

legacy internal control frameworks. In connection with Smurfit Westrock's assessment of its internal control over financial reporting

for the purposes of complying with Section 302 of SOX, we previously identified and reported a material weakness relating to the

company's selection and development of control activities intended to mitigate the risks to achieving its objectives. This relates to

certain processes and controls principally at historical Smurfit Kappa that were not subject to the requirements of Section 404 of SOX

prior to the Combination.

This material weakness resulted in:

• A lack of formalization of an existing control process for documenting evidence of management review and performance of

control procedures, including the level of precision in the execution of controls and procedures to ascertain completeness and

accuracy of information produced by the Company.

• Existing controls related to the preparation and review of manual journal entries not designed to adequately mitigate the

associated risks.

• The need to augment General IT Controls, specifically as they pertain to (i) logical access controls to ensure appropriate

segregation of duties and that adequately restrict user and privileged access to financial applications, programs, and data to

appropriate Company personnel and (ii) program change management controls to ensure that information technology

program and data changes affecting financial IT applications and underlying accounting records are identified, tested,

authorized and implemented appropriately.

Notwithstanding the identified material weakness, management believes that the Condensed Consolidated Financial Statements and

related financial information included in this Quarterly Report on Form 10-Q fairly present, in all material respects, our financial

position, results of operations and cash flows as of and for the periods presented.

*Remediation Plan*

The process of designing and implementing remediation measures is underway in respect of this material weakness and to improve our

internal control over financial reporting. These remediation measures include a number of ongoing actions which have been prioritized

in a material weakness remediation strategy that aligns to the most impactful controls:

• designing and implementing policies and guidance related to the operation of controls – a number of which have now been

designed and issued for execution;

• developing appropriate controls over the review of manual journal entries – including a phased roll out plan underway for the

implementation of an automated approval workflow for manual journal entries at relevant material locations in addition to a

risk-based interim manual control which has been designed and issued for execution; and

• enhancing and expanding across the organization the general IT processes and controls – with a prioritized focus on logical

access and change management.

In addition, control operators continue to participate in SOX training and live support sessions, with a specific focus on the priority

areas documented in the material weakness remediation strategy.

While we are working to remediate the identified deficiencies as timely and efficiently as possible, we cannot yet provide an estimate

of the time it will take to complete this remediation plan. The implementation of our remediation measures will require validation and

testing of the design and operating effectiveness of internal controls over a sustained period. In addition, we cannot ensure that the

measures taken by us to date, and actions that we may take in the future, will be sufficient to remediate these deficiencies or that they

will prevent or avoid potential future deficiencies.

**Changes in Internal Control over Financial Reporting**

Other than the changes that may continue to result from the integration following the Combination and remediation actions described

above, there has been no change in Smurfit Westrock's internal control over financial reporting (as such term is defined in Rules

13a-15(f) and 15d-15(f) under the Exchange Act) during the three months ended June 30, 2025 that has materially affected, or is

reasonably likely to materially affect, Smurfit Westrock's internal control over financial reporting.

**PART II - OTHER INFORMATION**

**Item 1. Legal Proceedings**

19. Subsequent Events" of theCondensed Consolidated Financial Statements (included in Part I, Item 1).

If a Participant has a Cash Deferral Election in effect, his or her Deferral Cash Account shall be credited from time to time with the cash compensation he or she elected to defer under § 4, and such credits shall be made as of the day on which such cash compensation would otherwise have been paid to him or her.

The Administration Committee shall from time to time select one, or more than one, Benchmark Fund based upon such criteria as it may from time to time determine and shall establish procedures to permit Participants to elect that credits or debits be made to their Deferred Cash Account which track the investment performance of the Benchmark Fund or funds which the Participant has elected to be used for this purpose. A Benchmark Fund may be a money market fund.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)Adjustment. The Administration Committee shall cause the balance in a Participant's' Deferred Cash Account to be adjusted up or down, at such intervals as it may from time to time determine, to reflect the investment performance of the Benchmark Fund or funds which the Participant elected that the balance credited to his or her Deferred Cash Account track; provided, that no Deferred Cash Account may at any time have a balance less than zero.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)Reports.

The number of Stock Units so credited shall equal the amount of the applicable Dividend Equivalent, divided by the Fair Market Value of a share of Common Stock as of the applicable payment date for the related dividend or distribution. Furthermore, the number of Stock Units credited to a Participant's Deferred Stock Account shall be adjusted by the Administration Committee as deemed appropriate to reflect any dividends paid in Common Stock and any changes in the Company's capital structure and to reflect any corporate transactions which result in adjustments to the Company's Common Stock.

A Participant may make a change to the form of payment elected under § 6.2(b) for the distribution of one hundred percent (100%) of his or her Deferred Cash Account after such election otherwise has become irrevocable under § 6.2(a) if, and only if,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)he or she files a Distribution Election Change Form with the Administration Committee which becomes irrevocable under this § 6.2(c) at least twelve (12) full months before the date on which the distribution of his or her Deferred Cash Account would have been made or would have begun but for such election change, and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)the distribution of his or her Deferred Cash Account to the Participant is delayed until at least five (5) years after the date on which the distribution of his or her Deferred Cash Account would have been made or would have begun but for such election change.

A Distribution Election Change Form shall become irrevocable on the date the form is filed with the Administration Committee; provided, however, any such election automatically shall be null and void *ab initio* if the election in retrospect fails to satisfy the requirement set forth in §6.2(c)(1). The Administration Committee shall have the right to limit the number election changes which a Participant may make under this § 6.2(c) to one election change. Finally,

------

the rules in this § 6.2(c) shall be interpreted by the Administration Committee to comply with the election change rules under § 409A of the Code.

§ 6.3 Stock Unit Accounts. The balance credited to each Participant's Stock Unit Account as of the date of the Participant's Termination of Board Membership shall be paid or distributed within 90 days after the end of the calendar quarter in which the Participant's Termination of Board Membership occurs, the exact date to be determined by the Administrative Committee acting in its discretion. The Participant's Stock Unit Account shall be paid through one issuance of Common Stock under the Incentive Stock Plan and one lump sum payment in cash in lieu of a fractional share of Common Stock based on the then Fair Market Value of a share of Common Stock.

§ 6.4 Death. If a Participant dies before his or her Account has been paid in full to the Participant, the balance then credited to the Participant's Account shall be paid in full to his or her Beneficiary in a lump sum within 90 days after the date of the Participant's death, the exact date to be determined by the Administration Committee acting in its discretion. The Participant's Deferred Cash Account shall be paid in cash and his or her Stock Unit Account shall be paid in accordance with § 6.3.
