This Current Report on Form 8-K 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) regarding, among other things, our Medium-Term Plan and any other statements regarding the Company's future expectations, beliefs, plans, objectives, results of operations, financial condition and cash flows, or future events, outlook or performance. Statements that are not historical facts, including statements about the beliefs and expectations of the management of the Company, 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" 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. Actual results may differ materially from the current expectations of the Company depending upon a number of factors affecting its business, including, but not limited to, our ability to deliver on our Medium-Term Plan and the risk factors discussed in the Company's filings with the Securities and Exchange Commission, including the Company's most recent Annual Report on Form 10-K. 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.

**Tony Smurfit, President and CEO, commented:**

"I am pleased to report a strong fourth quarter performance for Smurfit Westrock set against difficult market conditions. We are reporting, for the quarter, Net Income of $98 million and Adjusted EBITDA<sup>1</sup> of $1,172 million, with an Adjusted EBITDA Margin<sup>1</sup> of 15.5% with a strong Net Cash Provided by Operating Activities of $1,195 million and Adjusted Free Cash Flow<sup>1</sup> of $679 million.

"In 2025, we established a strong foundation for Smurfit Westrock. We exceeded our committed synergy target of $400 million and put in place a series of customer-centric, commercial and operating initiatives. We also reduced loss making businesses and closed approximately 600,000 tons of high-cost or inefficient capacity as we continued to focus on portfolio optimization. During the year, we further reduced headcount by over 3,000, while continuing to invest significantly behind our customers, in our asset base and operating efficiency. We will outline the expected benefits of the actions we have taken, and future actions, for the medium-term, during our earnings call later today.

"For our North America region, performance in the quarter reflects the impact of additional downtime taken to balance our system and actively manage working capital. As we continue to transition to a value-based selling approach, our corrugated businesses are already achieving a better business mix and are winning significant new business, setting a strong platform for the future. For our consumer business, while there are near-term capacity issues (primarily within SBS), we believe our strong and continued focus on efficiency, innovation and asset optimization together with an experienced management team positions this business for future performance.

<sup>1</sup> Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Free Cash Flow and Adjusted Basic EPS are non-GAAP measures. See the "Non-GAAP Financial Measures and Reconciliations" below for discussion and reconciliation of these measures to the most comparable GAAP measures.

<sup>2</sup> Smurfit Westrock plc's results for the full year ended December 31, 2024 appear in the consolidated financials included below. For the January 1, 2024 – July 5, 2024 time period, these results reflect the historical financial results of legacy Smurfit Kappa Group plc, which is considered the accounting acquirer in the combination between Smurfit Kappa Group plc and WestRock Company, which closed on July 5, 2024.

"For our EMEA and APAC region, our leading, integrated platform with strong market positions again delivered an outstanding performance. We continue to believe that our business within this region is optimally positioned for a strong, future recovery.

"The performance of our LATAM region reflects the strength of our market positions and the benefits of growth projects already completed. LATAM continues to be a region of significant growth and opportunity.

"During 2025, we made significant progress in establishing a performance-led culture, optimizing our operating model, and adopting a sharper, customer-centric focus. Through the quality of our people, along with our innovation and sustainability expertise, we are increasingly excited about our future. As we will outline later on, through our Medium-Term Plan, we have targeted an accelerated path to growth. With regard to current trading, while we have experienced significant weather events in North America and Europe, we see a generally better industry operating environment, which positions us well for continued performance in 2026. For the first quarter, we currently expect to deliver Adjusted EBITDA<sup>3</sup> of between $1.1 billion and $1.2 billion and for the full year, we currently expect to deliver Adjusted EBITDA<sup>3</sup> of between $5.0 billion and $5.3 billion."

**Dividend**

Smurfit Westrock plc announced on February 3, 2026 that its Board approved a quarterly dividend of $0.4523 per share on its ordinary shares. The quarterly dividend of $0.4523 per ordinary share is payable on March 18, 2026 to shareholders of record at the close of business on February 17, 2026.

The default payment currency is U.S. Dollar for shareholders who hold their ordinary shares through a Depository Trust Company participant. It is also U.S. Dollar for shareholders holding their ordinary shares in registered form, unless a currency election has been registered with the Company's Transfer Agent, Computershare Trust Company N.A. by 5:00 p.m. (New York) / 10:00 p.m. (Dublin) on February 13, 2026.

The default payment currency for shareholders holding their ordinary shares in the form of Depository Interests is U.S. Dollar. Such shareholders can elect to receive the dividend in Pounds Sterling or Euro by providing their instructions to the Company's Depositary Interest provider, Computershare Investor Services plc, by 12:00 p.m. (New York) / 5:00 p.m. (Dublin) on February 27, 2026.

**Earnings Call**

Management will host an earnings conference call today at 7:30 AM ET / 12:30 PM GMT to discuss Smurfit Westrock's financial results for the fourth quarter and full year ended December 31, 2025, together with an update for investors on its Medium-Term Plan, capital allocation priorities and value drivers. The conference call will be accessible through a live webcast. Interested investors and other individuals can access the webcast, earnings release, and earnings presentation via the Company's website at www.smurfitwestrock.com. The webcast will be available at https://investors.smurfitwestrock.com/overview and a replay of the webcast will be available on the website shortly after the call.

<sup>3</sup> Adjusted EBITDA is a non-GAAP financial measure. We have not reconciled Adjusted EBITDA outlook to the most comparable GAAP outlook because it is not possible to do so without unreasonable efforts due to the uncertainty and potential variability of reconciling items, which are dependent on future events and often outside of management's control and which could be significant. Because such items cannot be reasonably predicted with the level of precision required, we are unable to provide an outlook for the comparable GAAP measure (net income).

This press release 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) 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 Group plc and WestRock Company (the "Combination"), including, but not limited to, synergies, as well as our scale, geographic reach and product portfolio, our medium-term plan, demand outlook, operating environment and the impact of announced closures and additional economic downtime and any other statements regarding the Company's future expectations, beliefs, plans, objectives, results of operations, financial condition and cash flows, or future events, outlook or performance. Statements that are not historical facts, including statements about the beliefs and expectations of the management of the Company, are forward-looking 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.

Important factors that could cause actual results to differ materially from plans, estimates or expectations include: our ability to deliver on our medium-term plan; 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 US 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 prolonged or recurring U.S. federal government shutdowns and any resulting volatility in the capital markets or interruptions in the Company's access to capital; 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 the 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, US or UK administrations; legal proceedings instituted against the Company; 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 US corporation or be subject to certain unfavorable US 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 risk factors included in the Company's filings with the Securities and Exchange Commission, including the Company's Annual Reports on Form 10-K for the fiscal years ended December 31, 2024 and 2025.

**Non-GAAP Financial Measures and Reconciliations**

Smurfit Westrock reports its financial results in accordance with accounting principles generally accepted in the United States ("GAAP"). However, management believes certain non-GAAP financial measures provide 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. Smurfit Westrock management also uses these non-GAAP financial measures 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 measures we present may differ from similarly captioned measures presented by other companies. Smurfit Westrock uses the non-GAAP financial measures "Adjusted EBITDA", "Adjusted EBITDA Margin", "Adjusted Free Cash Flow" and "Adjusted Basic Earnings Per Share" (referred to as "Adjusted Basic EPS"). We discuss below details of the non-GAAP financial measures presented by us and provide reconciliations of these non-GAAP financial measures to the most directly comparable financial measures calculated in accordance with GAAP.

**Definitions**

Smurfit Westrock uses the non-GAAP financial measures "Adjusted EBITDA" and "Adjusted EBITDA Margin" to evaluate its overall performance. The composition of Adjusted EBITDA is not addressed or prescribed by GAAP. Smurfit Westrock defines Adjusted EBITDA as net income before 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, net, impairment and restructuring costs, transaction and integration-related expenses associated with the Combination, amortization of fair value step up on inventory and other specific items that management believes are not indicative of the ongoing operating results of the business.

Management believes Adjusted EBITDA and Adjusted EBITDA Margin measures provide Smurfit Westrock's management, Board of directors, investors, potential investors, securities analysts and others with useful information to evaluate Smurfit Westrock's 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. Adjusted EBITDA Margin is calculated as Adjusted EBITDA divided by Net Sales.

Smurfit Westrock uses the non-GAAP financial measure "Adjusted Free Cash Flow". Smurfit Westrock defines Adjusted Free Cash Flow as net cash provided by operating activities as adjusted for capital expenditures and to exclude certain costs not reflective of underlying ongoing operations. Management utilizes this measure in connection with managing Smurfit Westrock's business and believes that Adjusted Free Cash Flow is useful to investors as a liquidity measure because it measures the amount of cash generated that is available, after reinvesting in the business, to maintain a strong balance sheet, pay dividends, repurchase stock, service debt and make investments for future growth. It should not be inferred that the entire free cash flow amount is available for discretionary expenditures. By adjusting for certain items that are not indicative of Smurfit Westrock's underlying operational performance, Smurfit Westrock believes that Adjusted Free Cash Flow also enables investors to perform meaningful comparisons between past and present periods.

Smurfit Westrock uses the non-GAAP financial measure "Adjusted Basic EPS". Management believes this measure provides Smurfit Westrock's management, Board of directors, investors, potential investors, securities analysts and others with useful information to evaluate Smurfit Westrock's performance because it excludes, impairment and restructuring costs, transaction and integration-related expenses associated with the Combination, amortization of fair value step up on inventory and other specific items that management believes are not indicative of the ongoing operating results of the business. Smurfit Westrock and its Board of directors use this information when making financial, operating and planning decisions and when evaluating Smurfit Westrock's performance relative to other periods. Smurfit Westrock believes that the most directly comparable GAAP measure to Adjusted Basic EPS is Basic earnings per share attributable to common shareholders (referred to as "Basic EPS").

**Smurfit Westrock Medium-Term Investor Update** ****<br> *This announcement contains inside information*

**Dublin** **, Ireland – February 11, 2026 –** As previously announced, Smurfit Westrock plc ("Smurfit Westrock" or the "Company") (NYSE: SW, LSE: SWR) will host an update for investors on its Medium-Term Plan, capital allocation priorities and value creation plan (the "Investor Update") today at approximately 7:30 am ET (12:30 pm GMT), led by Group President & CEO Tony Smurfit alongside other members of the senior leadership team.

**2030 Financial Targets and Capital Allocation Priorities** **<sup>1</sup>**

At the event, Smurfit Westrock will set out and discuss its financial targets over the next five years (2026-2030):

&nbsp;&nbsp;&nbsp;&nbsp;· Adjusted
 EBITDA<sup>1</sup> of ~$7 billion by 2030

&nbsp;&nbsp;&nbsp;&nbsp;· Adjusted
 EBITDA CAGR<sup>1</sup> of ~7% over 2026-2030

&nbsp;&nbsp;&nbsp;&nbsp;· Adjusted
 EBITDA Margin<sup>1</sup> expansion of ~300 basis points over 2026-2030

&nbsp;&nbsp;&nbsp;&nbsp;· Cumulative
 Discretionary Free Cash Flow<sup>1</sup> of ~$14 billion over 2026-2030<sup>2</sup>

&nbsp;&nbsp;&nbsp;&nbsp;· Discretionary
 Free Cash Flow CAGR<sup>1</sup> of ~17% over 2026-2030

&nbsp;&nbsp;&nbsp;&nbsp;· Long-term
 Net Debt to EBITDA<sup>1</sup> target of below 2.0x

&nbsp;&nbsp;&nbsp;&nbsp;· Significant
 and growing capital return to shareholders, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o Maintaining
 a progressive dividend policy with dividends of ~$5 billion between 2026-2030

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o Capacity
 for share buybacks from 2027

Smurfit Westrock's Medium-Term Plan assumes market growth<sup>3</sup> and through-the-cycle pricing around current levels, including market growth of 1.6% in North America, 1.7% in Europe and 2.0% in Latin America. Achieving this plan assumes below mid-market paper pricing in Europe and no price increases in paper in North America. These assumptions are based on third party market data and our targets are not based on market improvements which would deliver additional upside. A presentation regarding the same will be available on the Company's website at www.smurfitwestrock.com before the event and also included with the Company's SEC filings.

**Tony Smurfit, President and CEO, commented:**

"Our Medium-Term Plan clearly sets out how we will continue to build Smurfit Westrock, as one of the world's great companies, delivering secure, superior, and long-term value for all of our stakeholders. The Investor Update will cover our five-year financial targets through 2030 and the capital allocation priorities that we believe will drive superior performance and enhanced shareholder returns, underpinned by our performance-led, owner-operator model.

Our strategy is straightforward, disciplined and proven. We are focused on unlocking the full potential of North America, while continuing to outperform in EMEA and APAC and delivering dynamic growth and strong margins in Latin America.

Strong operational performance and capital allocation are central to our value creation plan. We will continue to invest in growth while aiming to deliver significant and growing capital return to shareholders, supported by the strength and flexibility of our balance sheet and strong Free Cash Flow generation."

<sup>1.</sup> Adjusted EBITDA, Adjusted EBITDA CAGR, Adjusted EBITDA Margin, Cumulative Discretionary Free Cash Flow, Cumulative Discretionary Free Cash Flow CAGR and Long Term Net Debt to EBITDA are non-GAAP financial measures. We have not reconciled these forward-looking non-GAAP measures to the most comparable GAAP measures because it is not possible to do so without unreasonable efforts due to the uncertainty and potential variability of reconciling items, which are dependent on future events and often outside of management's control and which could be significant. Because such items cannot be reasonably predicted with the level of precision required, we are unable to provide forward-looking comparable GAAP measures. In addition, these goals are aspirational or otherwise constitute forward-looking statements. Actual performance may differ, possibly materially, and no guarantees are made that these goals will be met.

<sup>2.</sup> Excludes growth capex of $4bn.

<sup>3.</sup> Source: Numera.

**Conference Call**

The event will be broadcast via live webcast and registration details are available at investors.smurfitwestrock.com. Upon registration, participants will receive a link to access the webcast. Presentation materials will be available in person and in the Investors section of the Smurfit Westrock website.

A replay of the webcast will be accessible on the website following the event.

**Forward Looking Statements**

This press release 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) regarding, among other things, the plans, strategies, outcomes, outlooks, and prospects, both business and financial, of Smurfit Westrock, including, but not limited to the synergies and other expected benefits of the completed combination between Smurfit Kappa and WestRock as well as our scale, geographic reach, product portfolio, credit rating and level of debt and leverage ratio, demand outlook, market growth patterns, and mid-range plan, including with respect to our capital returns to shareholders (such as declaration of future dividends and/or share buybacks), planned investments and anticipated path to delivering shareholder value and any other statements regarding the Company's future expectations, beliefs, plans, objectives, capital allocation decisions, investment strategy and return on capital employed, results of operations, financial condition and cash flows, or future events, outlook, or performance. Statements that are not historical facts, including statements about the beliefs and expectations of the management of the Company, 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" 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. Actual results may differ materially from the current expectations of the Company depending upon a number of factors affecting its business, including risks associated with the integration and performance of the Company following the Combination. This press release provides an overview of the Company's goals, plans, and related initiatives. These goals, plans, and initiatives are aspirational or otherwise constitute forward-looking statements and actual performance may differ, possibly materially, and no guarantees are made that these goals will be met or that these plans and initiatives will be successfully executed. This presentation also includes numbers and percentages that are estimates or approximations and that may be based on various assumptions some but not all of which are provided herein. Some data and other information in this presentation are also based on management's estimates and calculations, which are derived from its review and interpretation of internal company research, surveys and independent sources. In addition, industry data included herein is subject to significant business, economic and competitive uncertainties beyond the Company's control.

Important factors that could cause actual results to differ materially from plans, estimates or expectations include: our ability to deliver on our mid-range plan, including with respect to our capital returns to shareholders, planned investments and growth;

**Non-GAAP Financial Measures**

Smurfit Westrock reports its financial results in accordance with GAAP. However, management believes certain non-GAAP financial measures provide 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. Smurfit Westrock management also uses these non-GAAP financial measures 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 measures we present may differ from similarly captioned measures presented by other companies. Smurfit Westrock uses the non-GAAP financial measures "Adjusted EBITDA", "Adjusted EBITDA CAGR", "Adjusted EBITDA Margin", "Adjusted Free Cash Flow", "Cumulative Discretionary Free Cash Flow", "Cumulative Discretionary Free Cash Flow CAGR" and "Long-Term Net Debt to EBITDA". We have not reconciled these forward-looking non-GAAP measures to the most comparable GAAP measures because it is not possible to do so without unreasonable efforts due to the uncertainty and potential variability of reconciling items, which are dependent on future events and often outside of management's control and which could be significant. Because such items cannot be reasonably predicted with the level of precision required, we are unable to provide forward-looking comparable GAAP measures.

Statements that are not historical facts, including statements about the beliefs and expectations of the management of the Company, 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" 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. Actual results may differ materially from the current expectations of the Company depending upon a number of factors affecting its business, including risks associated with the integration and performance of the Company following the Combination. Important factors that could cause actual results to differ materially from plans, estimates or expectations include: our ability to deliver on our medium-term plan; 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 US 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 prolonged or recurring U.S. federal government shutdowns and any resulting volatility in the capital markets or interruptions in the Company's access to capital; 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;

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 US corporation or be subject to certain unfavorable US 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 risk factors included in the Company's filings with the Securities and Exchange Commission, including the Company's Annual Reports on Form 10-K for the fiscal years ended December 31, 2024 and 2025.

However, management believes certain non-GAAP financial measures provide 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. Smurfit Westrock management also uses these non-GAAP financial measures 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 measures we present may differ from similarly captioned measures presented by other companies. Smurfit Westrock uses the non-GAAP financial measures "Adjusted EBITDA", "Adjusted EBITDA Margin" and "Adjusted Free Cash Flow". We discuss below details of the non-GAAP financial measures presented by us and provide reconciliations of these non-GAAP financial measures to the most directly comparable financial measures calculated in accordance with GAAP in the Appendix to this presentation. Definitions Smurfit Westrock uses the non-GAAP financial measures "Adjusted EBITDA" and "Adjusted EBITDA Margin" to evaluate its overall performance. The composition of Adjusted EBITDA is not addressed or prescribed by GAAP. Smurfit Westrock defines Adjusted EBITDA as net income before 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, net, impairment and restructuring costs, transaction and integration-related expenses associated with the Combination, amortization of fair value step up on inventory and other specific items that management believes are not indicative of the ongoing operating results of the business. Management believes Adjusted EBITDA and Adjusted EBITDA Margin measures provide Smurfit Westrock's management, Board of directors, investors, potential investors, securities analysts and others with useful information to evaluate Smurfit Westrock's 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. Adjusted EBITDA Margin is calculated as Adjusted EBITDA divided by Net Sales. Smurfit Westrock uses the non-GAAP financial measure "Adjusted Free Cash Flow". Smurfit Westrock defines Adjusted Free Cash Flow as net cash provided by operating activities as adjusted for capital expenditures and to exclude certain costs not reflective of underlying ongoing operations. Management utilizes this measure in connection with managing Smurfit Westrock's business and believes that Adjusted Free Cash Flow is useful to investors as a liquidity measure because it measures the amount of cash generated that is available, after reinvesting in the business, to maintain a strong balance sheet, pay dividends, repurchase stock, service debt and make investments for future growth. It should not be inferred that the entire free cash flow amount is available for discretionary expenditures. By adjusting for certain items that are not indicative of Smurfit Westrock's underlying operational performance, Smurfit Westrock believes that Adjusted Free Cash Flow also enables investors to perform meaningful comparisons between past and present periods. |

We have not reconciled Adjusted EBITDA outlook to the most comparable GAAP outlook because it is not possible to do so without unreasonable efforts due to the uncertainty and potential variability of reconciling items, which are dependent on future events and often outside of management's control and which could be significant. Because such items cannot be reasonably predicted with the level of precision required, we are unable to provide an outlook for the comparable GAAP measure (net income). |

All Rights Reserved. Non-GAAP Financial Measures Smurfit Westrock reports its financial results in accordance with U.S. generally accepted accounting principles ("GAAP"). However, management believes certain non-GAAP financial measures provide 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. Smurfit Westrock management also uses these non-GAAP financial measures 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 measures we present may differ from similarly captioned measures presented by other companies. Smurfit Westrock uses the non-GAAP financial measures "Adjusted EBITDA", "Adjusted EBITDA Margin", "Adjusted EBITDA CAGR", "Free Cash Flow", "Discretionary Free Cash Flow", "Discretionary Free Cash Flow CAGR" and "Net Leverage". We discuss below details of the non-GAAP financial measures presented by us. We have not reconciled these forward-looking non-GAAP measures to the most comparable GAAP measures because it is not possible to do so without unreasonable efforts due to the uncertainty and potential variability of reconciling items, which are dependent on future events and often outside of management's control and which could be significant. Because such items cannot be reasonably predicted with the level of precision required, we are unable to provide forward-looking comparable GAAP measures. Definitions Smurfit Westrock uses the non-GAAP financial measures "Adjusted EBITDA" and "Adjusted EBITDA Margin" to evaluate its overall performance. The composition of Adjusted EBITDA is not addressed or prescribed by GAAP. Smurfit Westrock defines Adjusted EBITDA as net income (loss) before 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, net, impairment and restructuring costs, transaction and integration-related expenses associated with the Combination, amortization of fair value step up on inventory and other specific items that management believes are not indicative of the ongoing operating results of the business. Adjusted EBITDA CAGR (compound annual growth rate) measures the mean annual growth rate of the Company's Adjusted EBITDA over a specified time period. Management believes Adjusted EBITDA and Adjusted EBITDA Margin measures provide Smurfit Westrock's management, board of directors, investors, potential investors, securities analysts and others with useful information to evaluate Smurfit Westrock's 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. Adjusted EBITDA Margin is calculated as Adjusted EBITDA divided by Net Sales. Smurfit Westrock defines the non-GAAP financial measure "Free Cash Flow" as net cash provided by operating activities as adjusted for capital expenditures. Management utilizes this measure in connection with managing Smurfit Westrock's business and believes that Free Cash Flow is useful to investors as a liquidity measure because it measures the amount of cash generated after reinvesting in the business, and that is available for dividends, acquisitions and other uses. Smurfit Westrock also uses the non-GAAP financial measure "Discretionary Free Cash Flow." Smurfit Westrock defines Discretionary Free Cash Flow as Free Cash Flow plus strategic capital expenditure. Discretionary Free Cash Flow CAGR (compound annual growth rate) measures the mean annual growth rate of the Company's Discretionary Free Cash Flow over a specified time period. Management utilizes this measure to assess cash flow before making strategic investment decisions. Smurfit Westrock uses the non-GAAP financial measure "Return on Capital Employed" ("ROCE"). Smurfit Westrock defines ROCE as the Company's segment adjusted EBITDA adjusted further for (i) unallocated corporate costs, (ii) depreciation, depletion and amortization expense, (iii) share based-compensation expense, and (iv) other expense (income), net, excluding finance costs or income included within (iv), divided by the Company's average capital employed, with capital employed for the applicable calendar year defined as the sum of the Company's (a) total equity, (b) current portion of debt and (c) non-current debt due after one year, less (d) cash and cash equivalents. The average capital employed is defined as the sum of the capital employed during the applicable calendar year and the capital employed during the calendar year preceding such year divided by two. Smurfit Westrock uses the non-GAAP financial measure "Net Leverage". Smurfit Westrock defines Net Leverage as Net Financial Debt divided by Adjusted EBITDA (as defined above). Net Financial Debt is defined as Financial Liabilities (short- and long-term) minus Cash and cash equivalents.
