Item 1A. RISK FACTORS

There are a number of risks and uncertainties that could have a material adverse effect on the Company’s businesses and its consolidated financial condition, results of operations or cash flows. The following risk factors should be considered, in addition to the other information included in this Form 10-K, when evaluating Tredegar and its businesses.

Risks Related to All of Tredegar’s Businesses

•Ongoing macroeconomic factors, including inflation, high interest rates and recession risks could cause downturns in key markets and create other commercial disruptions, which could adversely impact our businesses.Products sold to key end-use markets, including the B&C and consumer electronics markets, represent a significant portion of our revenue. Because these markets are tied closely to overall economic performance, macroeconomic factors could cause changes to demand for our products. These factors include: (i) inflation; (ii) high interest rates; (iii) recession risks; and (iv) other interruptions of international and regional commerce. Price erosion may occur as competitors become more aggressive in

4

pricing practices. To the extent that these factors reduce demand for our products, our business, financial position, results of operations and cash flows could be adversely impacted.

•Tredegar’s performance is influenced by costs incurred by its operating companies, including the cost of raw materials and energy. These costs include the cost of aluminum (the raw material on which Aluminum Extrusions primarily depends), resin (the raw material on which PE Films primarily depends), natural gas (the principal fuel necessary for Aluminum Extrusions’ plants to operate), electricity, diesel fuel, chemicals and paint. Aluminum, resin and natural gas prices are volatile as shown in the charts in Item 7A. The Company attempts to mitigate the effects of increased costs through price increases and contractual pass-through provisions, but there are no assurances that higher prices can effectively be passed through to customers or that Tredegar will be able to offset fully or on a timely basis the effects of higher costs. Further, the Company’s cost control efforts may not be sufficient to offset any increases in raw materials, energy or other costs.

•Noncompliance with any of the covenants in the Company’s $125 million asset-based revolving credit facility (“ABL Facility”), which matures on June 30, 2026, could result in all debt outstanding thereunder becoming due and limiting the Company’s borrowing capacity, which could have a material adverse effect on its consolidated financial condition and liquidity. The credit agreement governing Tredegar’s ABL Facility contains restrictions and financial covenants that, if violated, could restrict the Company’s operational and financial flexibility. Failure to comply with these covenants could result in an event of default, which if not cured or waived, would result in all outstanding debt under the credit facility at such time becoming due, which could have a material adverse effect on the Company’s consolidated financial condition and liquidity.

•Our failure to continue to attract, develop and retain certain key officers or employees could adversely affect our businesses. Our success depends upon the efforts and abilities of key personnel, many of whom are longstanding employees. The loss of any of these key personnel could deplete our institutional knowledge base and negatively affect our ability to efficiently operate our businesses. Certain roles have experienced high turnover in recent years, and we are experiencing an increasingly competitive labor market. Increased employee turnover could hinder our ability to execute our business strategy and adversely affect our business, financial condition, results of operations and cash flows.

•Disruptions at one of the Company’s major manufacturing facilities could negatively impact financial results. Tredegar believes it has implemented measures to minimize the risks of disruption at its facilities. However, a disruption could occur as a result of any number of events: an equipment failure with repairs requiring long lead times, labor stoppages or shortages, cybersecurity attacks, utility disruptions, constraints on the supply or delivery of critical raw materials, and severe weather conditions, including potential flooding at the Aluminum Extrusions facility located in Carthage, TN, which is located in a 50-year flood plain. A material disruption in one of the Company’s operating locations could negatively impact production and the Company’s consolidated financial condition, results of operations and cash flows.

•A failure in the Company’s information technology systems as a result of cybersecurity attacks or other causes could negatively affect Tredegar’s business. The Company depends on information technology (“IT”) to record and process customer orders, manufacture and ship products in a timely manner, secure its production processes and know-how, maintain the financial accuracy of its business records and maintain personally identifiable information of its employees. An IT system failure due to computer viruses, internal or external security breaches, cybersecurity attacks or other malicious causes could disrupt our operations and prevent us from being able to process transactions with our customers, operate our manufacturing facilities and properly report transactions in a timely manner. Increased global IT security threats and cyber-crime pose a potential risk to the security and availability of the Company’s IT systems, networks and services, including those that are managed, hosted, provided or used by third parties, as well as to the confidentiality, availability and integrity of the Company’s data. Additionally, increased cybersecurity risk arises due to certain employees working remotely. To date, interruptions of the Company’s IT systems have been infrequent, and Tredegar has not experienced a material cybersecurity incident. A significant prolonged failure of or security breach of the IT systems, networks or service providers the Company relies upon, or a loss or disclosure of business or other sensitive information, or personally identifiable information, as a result of a cybersecurity incident or other cause, could result in substantial costs to the Company, damage to the Company’s reputation, regulatory enforcement actions and lawsuits and could adversely affect the Company’s business, results of operations, financial condition or cash flows.

•Trade policies could cause an increase in the cost of our products or otherwise negatively impact the Company. The primary raw materials used by Aluminum Extrusions consist of aluminum ingot, aluminum scrap and various alloys, which are purchased from domestic and foreign producers in open-market purchases and under short-term contracts. PE Film’s Surface Protection business involves imports to and from the U.S. and other countries where the Company produces and sells its products, including China. Trade tensions have been rising between the U.S. and other countries. An increase in tariffs and other trade barriers between the U.S. and other countries could cause disruption to supply chains

5

and an increase in the cost of Aluminum Extrusions’ and PE Films’ products or otherwise negatively impact the production and sale of the Company’s products in world markets.

•The Company’s results of operations, financial condition and cash flows have been and could be impacted by the macroeconomic effects of a pandemic.The COVID-19 pandemic had multiple adverse effects on the global economy, including short-term impacts affecting labor supply and causing supply chain disruptions which led to inflationary pressures. In addition, the pandemic resulted in certain after-shocks and structural shifts, which have adversely impacted Tredegar’s markets.

In the event of a future pandemic, Tredegar’s businesses, our suppliers, contractors and third-party logistic providers could experience conditions similar to those associated with the COVID-19 pandemic, including facility closures, labor constraints, supply chain disruptions and other challenges. These challenges could impact our ability to maintain sufficient inventory and to accurately predict demand or lead times, which could inhibit our ability to service customer demand. Additionally, a future pandemic could heighten other risks described herein.

•Tredegar is subject to current and future government regulations, including environmental laws and regulations, and could become exposed to liabilities and costs associated with such regulations. The Company is subject to regulation by local, state, federal and foreign governmental authorities. New laws and regulations, or changes to existing laws, including those relating to environmental matters (including global climate change and plastic products), and privacy matters, could subject Tredegar to significant additional capital expenditures, operating expenses or other compliance costs. Moreover, future developments in federal, state, local and international laws and regulations, including environmental laws, are difficult to predict. Environmental laws and privacy restrictions have become and are expected to continue to become increasingly strict. As a result, Tredegar expects to be subject to new environmental and privacy laws and regulations. However, any such changes are uncertain and, therefore, it is not possible for the Company to predict with certainty the amount of additional capital expenditures or operating expenses that could be necessary for compliance with respect to any such changes.

The Company is subject to the U.S. Foreign Corrupt Practices Act, anti-corruption laws and similar anti-bribery laws in other jurisdictions, which generally prohibit companies and their intermediaries from making improper payments to foreign officials for the purpose of obtaining or retaining business. Although we have policies and procedures designed to facilitate compliance with these laws and regulations, our employees, contractors and agents may take actions in violation of our policies. Any such violation, even if prohibited by our policies, could adversely affect our business and/or our reputation.

Risks Related to Aluminum Extrusions

•Sales volume and profitability of Aluminum Extrusions is cyclical and seasonal and highly dependent on economic conditions of end-use markets in the U.S., particularly in the construction sector. Aluminum Extrusions’ end-use markets can be cyclical and subject to seasonal swings in volume. In addition, changes in architectural design, demographic, and remote work trends could negatively impact the overall commercial construction industry. Because of the capital-intensive nature and level of fixed costs inherent in the aluminum extrusions business, the percentage drop in earnings before interest, taxes, depreciation and amortization (“EBITDA”) from ongoing operations in a cyclical downturn will likely exceed the percentage drop in volume. In addition, during an economic slowdown, excess industry capacity often drives increased pricing pressure in many end-use markets as competitors seek to maintain or increase their position with key customers. Benefits associated with cost reductions and productivity improvements may not be sufficient to offset the adverse effects on profitability from pricing and margin pressure and higher bad debts (including a greater chance of loss associated with customers defaulting on fixed-price forward sales contracts) that usually accompany a downturn.

•Unfairly traded imports of aluminum extrusions could injure or threaten with injury America’s domestic aluminum extrusions industry, which could have an adverse effect on the financial condition, results of operations and cash flows of Aluminum Extrusions. Chinese and other foreign manufacturers continue to try to evade the antidumping and countervailing orders to avoid duties. In October, 2022, the U.S. International Trade Commission (“ITC”) extended the antidumping and countervailing duty orders against aluminum extrusions from China for a period of five years.

In March 2018, the U.S. imposed tariffs of 10% on aluminum ingot and semi-finished aluminum imported into the U.S. from certain countries (“Section 232 tariffs”). In December 2020, the Department of Commerce (“USDOC”) introduced a tariff exclusion process, allowing importers to bypass individual exclusion requests and import items without Section 232 tariffs.

The Company participated as a member of the U.S. Aluminum Extruders Coalition which filed a trade case with the USDOC and the U.S. International Trade Commission (“USITC”) against 15 countries in response to alleged large and increasing volumes of unfairly priced imports of aluminum extrusions since 2019. In November 2023, the USITC found that there is a reasonable indication that the American aluminum extrusions industry is materially injured or threatened

6

with injury due to imports from 14 countries, including China. In September 2024, the USDOC announced its final determinations that aluminum extrusion producers and exporters in 14 countries, including China, sold aluminum extrusions at less-than-fair value in the U.S. In October 2024, the USITC found that U.S. producers had not been materially injured by reason of the subject imports, despite the USDOC findings of less-than-fair value pricing by those imports. The coalition has appealed the decision.

The USITC negative determination in October did not impact the existing duties on aluminum extrusions from China.

On February 10, 2025, the Section 232 tariffs on all aluminum imports were increased from 10% to 25%, effective March 12, 2025, and certain country-specific and product-specific exclusions from the tariffs were revoked. This action also expands the scope of the tariffs to include downstream products, including certain finished aluminum goods. These measures, which apply in addition to existing antidumping and countervailing duties, are intended to prevent the circumvention of duties through the importation of downstream products. The actual level and timing of the tariffs remains a fluid situation. A failure by, or the inability of, U.S. trade officials to restore the import tariff in its full format could have an adverse effect on the businesses, financial condition, results of operations and cash flows of Aluminum Extrusions.

•The markets for Aluminum Extrusions’ products are highly competitive with product quality, service, delivery performance and price being the principal competitive factors. Aluminum Extrusions has approximately 1,100 customers that are in a variety of end-use markets within the broad categories of building and construction, automotive, transportation, consumer durables, electrical, renewable energy, machinery and equipment, and distribution. No single Aluminum Extrusions’ customer exceeds 2% of consolidated net sales. Future success and prospects depend on Aluminum Extrusions’ ability to provide superior service, high quality products, timely delivery and competitive pricing to retain existing customers and participate in overall industry cross-cycle growth. Failure in any of these areas could lead to a loss of customers, which could have an adverse effect on the business, financial condition, results of operations and cash flows of Aluminum Extrusions.

•The failure to successfully implement the new enterprise resource planning and manufacturing execution systems could adversely impact the Aluminum Extrusions business and results of operations. InJanuary 2022, Aluminum Extrusions commenced the implementation of new enterprise resource planning and manufacturing execution systems (“ERP/MES”) across all locations of the Aluminum Extrusions business. The implementation of these systems is a major undertaking from a financial, management, and personnel perspective. The implementations have been more difficult, time-consuming and costly (approximately $21 million of spending to date) than expected. This project has been reorganized with the timing for the go-live date being uncertain. There can be no assurance that these systems will be beneficial to the extent anticipated. Conversely, our existing systems could become obsolete, fail to function properly or otherwise fail to address our needs. Any additional disruptions, delays or deficiencies in the design and implementation of the new systems could adversely affect our financial position, results of operations and cash flows.

Risks Related to PE Films

•PE Films is highly dependent on sales associated with relatively few large customers. PE Films’ top four customers comprised in total approximately 16%, 12% and 12% of Tredegar’s consolidated net sales in 2024, 2023 and 2022, respectively. The loss or significant reduction of sales associated with one or more of these customers without replacement by new business could have an adverse effect on the Company.

While PE Films is undertaking efforts to expand its customer base, there can be no assurance that such efforts will be successful, or that they will offset any loss of sales and profits associated with large customer declines.

•The failure of PE Films’ customers to achieve success or maintain market share could adversely impact PE Films’ sales and operating margins. PE Films’ specialized protection and polyethylene overwrap films are used in the production of various consumer products sold worldwide. Our customers’ ability to successfully develop, manufacture and market those products is integral to PE Films’ success. Cyclical downturns and changing consumer preferences, particularly those driven by changes in technology, may negatively affect businesses that use PE Films’ film products, which could adversely affect sales and operating margins. Other factors that could adversely affect the business include (i) failure by a key customer to achieve success or maintain share in markets in which they sell products containing PE Films’ materials, including as a result of customer preferences for products other than films, (ii) key customers using products developed by others that replace PE Films’ business with such customers, (iii) delays in a key customer rolling out products utilizing new technologies developed by PE Films, and (iv) operational decisions by a key customer that result in component substitution, inventory reductions and similar changes.

•The Company’s inability to protect its intellectual property rights or its infringement of the intellectual property rights of others could have an adverse impact on PE Films. The continued success of PE Films’ business depends on its ability not only to protect its own technologies and trade secrets, but also to develop and sell new products that do not infringe upon existing patents. Intellectual property litigation is very costly and could result in substantial expense and diversions

7

of Company resources, both of which could adversely affect its consolidated financial condition, results of operations and cash flows. In addition, there may be no effective legal recourse against infringement of the Company’s intellectual property by third parties, whether due to limitations on enforcement of rights in foreign jurisdictions or as a result of other factors.

Item 1B. UNRESOLVED STAFF COMMENTS

None.

Item 1C. CYBERSECURITY

Tredegar’s business model depends on the efficiency and reliability of its information systems, networks, and essential assets, with a portion of these systems and networks being administered by third-party service providers. Tredegar’s Cybersecurity Program (the “Program”), which was designed utilizing a risk-based approach, was developed to not only prevent, identify, investigate, resolve, and mitigate potential cybersecurity vulnerabilities within Tredegar but also to enhance the information security posture of Tredegar’s operations involving third-party service providers.

Tredegar entrusts its third-party service providers with the responsibility to institute security measure protocols that are appropriately and proportionally tailored to the corresponding risks. However, Tredegar also periodically conducts assessments of the third-party service providers’ security frameworks to verify the implementation of adequate security measures, to safeguard Tredegar against potential vulnerabilities.

The Program leverages a blend of automated systems, manual operations, and external evaluations to proactively identify and mitigate potential cybersecurity threats. Key components of the Program include Tredegar’s Cybersecurity Incident Response Plan and Cyber Crisis Management Plan. These plans encompass a strategic approach that includes: (i) detection of threats, thorough analysis of cybersecurity incidents to determine whether timely notification to Tredegar’s Board of Directors (“Board”) is necessary; (ii) containment of incidents; (iii) eradication or mitigation of threats; (iv) recovery processes; and (v) a comprehensive post-incident review.

To further strengthen its cybersecurity posture, Tredegar employs third-party consultants who work with the internal audit and information technology (“IT”) functions to assess Tredegar’s information security program and practices, including incident management, service continuity, and information security compliance programs, and identify areas for improvement. The results of such an assessment are regularly presented to the Audit Committee. Notably, these assessments include periodic penetration tests, which allow Tredegar to identify vulnerabilities, refine procedures, and enhance its crisis management and recovery capabilities. The Program is also supported by an organizational structure, involving collaboration across various business sectors and an interdisciplinary Global Data Protection and Cybersecurity Oversight Team that meets regularly to identify information security risks and appropriate risk mitigation strategies. Additionally, because Tredegar recognizes the significant role that its employees play in information security, it provides annual formal information security training to all of its employees that covers critical topics such as phishing and email security best practices. Furthermore, periodic simulated phishing exercises are conducted to reinforce these practices.

Tredegar’s IT Director and Bonnell’s Director of Information Security are responsible for managing the Program, including the prevention, mitigation, detection and remediation of cybersecurity incidents. Tredegar’s IT Director has over 10 years of cybersecurity expertise, including working in similar roles at other companies, has cybersecurity certifications from EC-Council and ODU Global and holds a degree in Computer Science from Universidade Catolica de Pernambuco and an MBA in IT Management from Universidade Federal de Pernambuco. Bonnell’s Director of Information Security has over 30 years of cybersecurity experience, including working in similar roles at other companies, has cybersecurity certifications from EC-Council and ISC^2 and holds a degree in Mechanical Engineering from the Georgia Institute of Technology. Tredegar’s IT Director and Bonnell’s Director of Information Security also regularly collaborate closely with key management, including the Chief Financial Officer, General Counsel, Compliance Manager, and Human Resources Executive Director, to foster effective communication regarding the Program within Tredegar.

The Board is responsible for risk management, with specific oversight of cybersecurity risks being delegated to the Audit Committee.The Audit Committee receives updates from Tredegar’s and Bonnell’s IT Directors at each of its quarterly meetings. These updates encompass an assessment of Tredegar’s cybersecurity risk profile, including the efficacy of Tredegar’s cybersecurity policies, procedures, strategies, and areas of emerging risk. Additionally, the Board receives annual, but often more frequent, updates on Tredegar’s cybersecurity systems.

Based on the information we have as of the date of this Form 10-K, we do not believe any risks from cybersecurity threats, including as a result of any previous cybersecurity incidents, have materially affected us, including our business strategy, results of operations or financial condition. See Item 1A. Risk Factors for further information.

Item 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of our financial condition and results of operations focuses on and is intended to clarify the results of our operations, certain changes in our financial position, liquidity, capital structure and business developments for the periods covered by the consolidated financial statements included in this Form 10-K. This discussion should be read in conjunction with, and is qualified by reference to, the other related information including, but not limited to, the audited consolidated financial statements (including the notes thereto) and the description of our business, all as set forth in this Form 10-K, as well as the risk factors discussed above in Item 1A.

This section provides discussion and a year-to-year comparison for the years ended December 31, 2024 and 2023 and for the years ended December 31, 2023 and 2022.

Business Overview

General

Tredegar Corporation is an industrial manufacturer with two primary businesses: custom aluminum extrusions for the B&C, automotive and specialty end-use markets in the United States through its Aluminum Extrusions segment (with exports comprising less than 5% of total sales volume) and surface protection films for high-technology applications in the global electronics industry through its PE Films segment. With approximately 1,500 employees, the Company operates manufacturing facilities in the U.S. and China.

EBITDA from ongoing operations is the measure of segment profit and loss used by Tredegar’s chief operating decision maker (“CODM”) for purposes of assessing financial performance. The Company uses sales less freight (“net sales”) as its measure of revenues from external customers at the segment level. This measure is separately included in the financial information regularly provided to the CODM.

Earnings before interest and taxes (“EBIT”) from ongoing operations is a non-GAAP financial measure included in the reconciliation of segment financial information to consolidated results for the Company in the Segment Operations Review section below. EBIT is not intended to represent the stand-alone results for Tredegar's ongoing operations under GAAP and should not be considered as an alternative to net income (loss) as defined by GAAP. We believe that EBIT is a widely understood and utilized metric that is meaningful to certain investors and that including this financial metric in the reconciliation of management’s performance metric, EBITDA from ongoing operations, provides useful information to those investors that primarily utilize EBIT to analyze the Company’s core operations.

Sales were $598.0 million in 2024 compared to $573.3 million in 2023. Net income (loss) from continuing operations was $1.0 million ($0.03 per diluted share) in 2024, compared with net income (loss) from continuing operations of $(99.2) million ($(2.91) per diluted share) in 2023.

2024 Financial Results Highlights

•EBITDA from ongoing operations for Aluminum Extrusions of $41.4 million was $3.4 million higher than the year of 2023.

•EBITDA from ongoing operations for PE Films of $30.5 million was $19.3 million higher than the year of 2023.

Gains and losses associated with exit and disposal activities, plant shutdowns, asset impairments, restructurings and other items are described in Results of Operations below.

(In thousands)

Income tax expense (benefit) (51,300)

Change in income (loss) from increases (decreases) in the following items:

Other income (expense), net 1,197

Change in income (loss) from (increases) decreases in the following items:

Pension and postretirement benefits 10,627

Interest expense 1,652

Pension settlement loss 92,291

Goodwill impairment 21,620

Income tax expense (benefit) (165)

Sales in 2024 increased by 4.3% compared with 2023. Net sales were relatively flat in Aluminum Extrusions primarily due to flat sales volume and the pass-through of higher metal costs, partially offset by a lower average conversion price add-on to metal costs associated with a shift in sales mix. Net sales increased 37.0% in PE Films primarily due to higher net sales and volume in Surface Protection, with extremely high sales in the first half of 2024 associated with the restocking of Surface Protection customers’ inventories. Overwrap films volume increased 14% versus 2023, primarily due to volume increases associated with lower margin business. For more information on changes in net sales and volume, see the Segment Operations Review section below.

Other income (expense), net was $(1.0) million in 2024 compared to $(2.1) million in 2023. The amount in other income (expense), net for 2024 was primarily related to $1.3 million of deferred and discretionary incentive payments made in 2024 subsequent to the sale of Terphane. The amount in other income (expense), net for 2023 was primarily related to a $2.0 million charge to adjust the initial purchase price of the nonparticipating single premium group annuity contract as a result of the routine administrative process to transition the pension plan.

Consolidated gross profit (sales minus cost of goods sold and freight) as a percentage of sales (gross profit margin) was 16.1% in 2024 versus 12.4% in 2023.

•The gross profit margin in Aluminum Extrusions increased primarily due to favorable variable manufacturing costs, higher labor productivity and higher volume, partially offset by higher labor and employee-related costs and lower spread (the difference between selling prices and metal costs) associated with a shift in sales mix. Additionally, inventories accounted for under the last-in first-out (“LIFO”) inventory method resulted in a charge of $1.2 million in 2024 versus a benefit of $0.9 million in 2023. The timing of the flow-through under the first-in first-out (“FIFO”) method of aluminum raw material costs, which were previously acquired in a quickly changing commodity pricing environment, causing a temporary mismatch in the change in the cost of raw materials included in variable costs and

12

the pass through to customers included in sales, resulted in a benefit of $1.4 million in 2024 versus a charge of $1.0 million in 2023.

•The gross profit margin in PE Films increased primarily due to higher contribution margin (net sales less variable costs) from Surface Protection associated with substantially higher volume, favorable pricing, operating efficiencies and variable cost savings in 2024 versus 2023. Inventories accounted for under the LIFO method resulted in a benefit of $0.2 million in 2024 versus a benefit of $1.3 million in 2023, and the pass-through lag associated with resin costs resulted in a charge of $1.0 million in 2024 versus a charge of $0.5 million in 2023.

For more information on changes in operating costs and expenses, see the Segment Operations Review section below.

As a percentage of sales, selling, general and administrative (“SG&A”) and R&D expenses were 12.3% in 2024 compared with 11.9% in 2023. While SG&A expense increased 11.6% and R&D decreased 75.4% year-over-year, sales increased $24.7 million or 4.3% compared with the prior year period. Higher SG&A spending was primarily due to higher employee-related compensation and higher professional fees associated with business development activities. Lower R&D spending was primarily due to lower costs associated with the closure of the PE Films technical center in Richmond, VA in 2023.

Pension and postretirement benefits was $0.2 million in 2024 compared to $10.8 million in 2023. The change in pension and postretirement benefits was primarily due to lower pension expense as a result of the pension plan termination completed in 2023. During 2023, the Company settled the pension plan, which resulted in a pre-tax pension settlement loss in the consolidated results of operation of $92.3 million. On November 3, 2023, the pension plan termination and settlement process was completed, and the Company’s relevant pension plan obligation was transferred to Massachusetts Mutual Life Insurance Company. See Note 8 “Retirement Plans and Other Postretirement Benefits” to the Consolidated Financial Statements in Item 15 for more information.

During 2024, a non-cash goodwill impairment of $13.3 million was recognized associated with the Clearfield, Utah operation reporting unit in Aluminum Extrusions. During 2023, a non-cash partial goodwill impairment of $34.9 million was recognized associated with the Surface Protection reporting unit in PE Films. See Note 1 “Nature of Operations and Summary of Significant Accounting Policies” to the Consolidated Financial Statements in Item 15 for more information.

The effective tax rate used to compute income taxes from continuing operations for the year of 2024 was (18.8)%, compared to 34.1% in 2023. The decrease in the effective tax rate is primarily due to pre-tax income from continuing operations in 2024 versus a pre-tax loss from continuing operations in 2023. The tax rate in 2023 was significantly impacted by tax benefits previously recorded in other comprehensive income (loss) that were released in 2023 as a result of the pension plan termination. The stranded taxes released with the termination of the pension plan represent the effect of the change in federal and state tax rates on pension-related deferred tax items initially recorded in other comprehensive income. The related stranded taxes were released in full in 2023. See Note 11 “Income Taxes” to the Consolidated Financial Statements in Item 15 for additional information.

Pre-tax gains and losses associated with plant shutdowns, asset impairments, restructurings and other items in 2024 detailed below are shown in the reconciliation of net sales and EBITDA from ongoing operations by segment in the Segment Operations Review below and are included in “Asset impairments and costs associated with exit and disposal activities, net of adjustments” in the consolidated statements of income, unless otherwise noted.

Sales in 2023 decreased by 24.8% compared with 2022. Net sales decreased 25.6% in Aluminum Extrusions primarily due to lower sales volume and the pass-through of lower metal costs. Net sales decreased 21.3% in PE Films primarily due to lower volume in Surface Protection, resulting from weak demand in the consumer electronics market and customer inventory corrections during 2023. For more information on changes in net sales and volume, see the Segment Operations Review section below.

Other income (expense), net was $(2.1) million in 2023 compared to $1.1 million in 2022. The change in other income (expense), net was primarily due to a $2.0 million charge to adjust the initial purchase price of the nonparticipating single premium group annuity contract as a result of the routine administrative process to transition the pension plan. Also, there was cash consideration of $0.3 million received in January 2023 compared to $1.4 million received in May 2022 related to customary post-closing adjustments on the sale of the investment in kaleo, Inc., which was sold in December 2021.

Consolidated gross profit (sales minus cost of goods sold and freight) as a percentage of sales (gross profit margin) was 12.4% in 2023 versus 13.8% in 2022.

•The gross profit margin in Aluminum Extrusions decreased primarily due to lower volume, lower labor productivity in the first half of 2023, higher supply expense, including higher paint expense associated with a shift to more painted product throughout 2023 and inflationary costs for other supplies, partially offset by lower utility costs and unfavorable LIFO inventory adjustments. The timing of the flow through under the FIFO method of aluminum raw material costs, which were previously acquired in a quickly changing commodity pricing environment, causing a temporary mismatch in the change in the cost of raw materials included in variable costs and the pass through to customers included in sales, resulted in a charge of $1.0 million in 2023 versus a benefit of $0.1 million in 2022. There were lower fixed manufacturing costs primarily due to lower non-production utility costs, and lower employee compensation. In addition, the Company recorded an unfavorable out-of-period adjustment of $0.4 million related to inventory and accrued labor costs in 2022.

•The gross profit margin in PE Films increased primarily due to higher overwrap films contribution margin associated with higher volume, favorable mix and favorable pricing, operating efficiencies and cost improvements and favorable LIFO inventory adjustments for both Surface Protection and overwrap films in 2023 versus 2022, partially offset by lower contribution margin for Surface Protection associated with a market slowdown, customer

15

inventory corrections and for previously disclosed customer product transitions. In addition, fixed manufacturing costs were lower primarily due to employee compensation and fixed cost savings.

For more information on changes in operating costs and expenses, see the Segment Operations Review section below.

As a percentage of sales, SG&A and R&D expenses were 11.9% in 2023 compared with 9.8% in 2022. While SG&A and R&D expenses decreased 6.1% and 45.6% year-over-year, sales decreased $188.7 million or 24.8% compared with the prior year period. Lower SG&A spending was primarily due to lower employee-related compensation and lower stock-based compensation. Lower R&D spending was primarily due to the closure of the technical center in Richmond, VA.

For more information on changes in interest expense, see the “Corporate Expenses, Interest and Other” section of the Segment Operations Review section below.

During 2023, the Company settled the pension plan, which resulted in a pre-tax pension settlement loss in the consolidated results of operation of $92.3 million. On November 3, 2023, the pension plan termination and settlement process was completed, and the Company’s relevant pension plan obligation was transferred to Massachusetts Mutual Life Insurance Company. See Note 8 “Retirement Plans and Other Postretirement Benefits” to the Consolidated Financial Statements in Item 15 for more information.

During 2023, a non-cash partial goodwill impairment of $34.9 million was recognized associated with the Surface Protection reporting unit in PE Films, see Note 1 “Nature of Operations and Summary of Significant Accounting Policies” to the Consolidated Financial Statements in Item 15 for more information.

The effective tax rate used to compute income taxes from continuing operations for the year of 2023 was 34.1%, compared to (31.6)% in 2022. The increase in the effective tax rate is primarily due to tax benefits previously recorded in other comprehensive income (loss) that were released as a result of the pension plan termination, partially offset by a reduction in Brazilian tax incentives as a percentage of income. The stranded taxes released with the termination of the pension plan represent the effect of the change in federal and state tax rates on pension-related deferred tax items initially recorded in other comprehensive income. The related stranded taxes were released in full in 2023. See Note 11 “Income Taxes” to the Consolidated Financial Statements in Item 15 for additional information.

Pre-tax gains and losses associated with plant shutdowns, asset impairments, restructurings and other items in 2023 detailed below are shown in the reconciliation of net sales and EBITDA from ongoing operations by segment table in the Segment Operations Review below and are included in “Asset impairments and costs associated with exit and disposal activities, net of adjustments” in the consolidated statements of income, unless otherwise noted.

Segment Operations Review

2024 versus 2023

A summary of operating results for 2024 versus 2023 for both of the Company’s reporting segments is shown below.

Aluminum Extrusions

A summary of results for Aluminum Extrusions is provided below:

Year Ended Favorable/

(In thousands, except percentages) December 31, (Unfavorable)

Last-in first-out inventory adjustment 1,234 (944) NM*

Net sales in 2024were relatively flat versus 2023 primarily due to flat sales volume and the pass-through of higher metal costs, partially offset by a lower average conversion price add-on to metal costs associated with a shift in sales mix.

EBITDA from ongoing operations increased $3.4 million in 2024 versus 2023, primarily due to:

•A $7.9 million increase in contribution margin associated with:

◦Favorable variable manufacturing costs ($4.8 million), higher labor productivity ($2.5 million) and higher volume ($0.5 million), partially offset by higher labor and employee-related costs ($2.2 million) and lower spread associated with a shift in sales mix ($1.4 million); and

◦The timing of the flow-through under the FIFO method of aluminum raw material costs, which were previously acquired in a quickly changing commodity pricing environment, causing a temporary mismatch in the change in the cost of raw materials included in variable costs and the pass through to customers included in sales, resulted in a benefit of $1.4 million in 2024 versus a charge of $1.0 million in 2023.

•Inventories accounted for under the LIFO method resulted in a charge of $1.2 million in 2024 versus a benefit of $0.9 million in 2023;

•Lower manufacturing fixed costs of $0.9 million primarily due to lower employee-related compensation and reduced outside services ($1.2 million); and

•Higher SG&A expenses of $3.9 million primarily due to employee-related incentive compensation ($2.7 million) and headquarters rent expenses ($0.6 million).

Aluminum Extrusions believes that it has adequate supply agreements for aluminum and other product cost components in 2025. See discussion of quantitative and qualitative disclosures about market risk in Item 7A in this Form 10-K for additional information on aluminum price trends.

Goodwill Impairment at Bonnell

During the fourth quarter of 2024, the Company recognized a non-cash write-off of goodwill of $13.3 million ($10.4 million after deferred income tax benefits) associated with the Clearfield, Utah operation ("Clearfield") acquired in February 2017 (formerly Futura). Clearfield exceeded expectations in performance, including exceptional customer service, from the date of acquisition until before pandemic-related disruptions that resulted in long lead times during periods of 2021 and 2022. Long lead times resulted in customers seeking supply from other sources to meet their demand, including imports. Some business lost at Clearfield during this time has been regained during the recovery underway, but not at the level that the Company previously anticipated would eventually replicate the EBITDA and net cash flow generation that existed prior to the pandemic-related disruptions. As a consequence, using projections that assume the continuation of lower sales and profitability, the estimated fair value of Clearfield during the fourth quarter of 2024 fell below its carrying value by more than the amount of goodwill causing the write-off.

Projected Capital Expenditures and Depreciation & Amortization

Capital expenditures for Bonnell Aluminum are projected to be $17 million in 2025, including $5 million for productivity projects and $12 million for capital expenditures required to support continuity of operations. Depreciation expense is projected to be $16 million in 2025. Amortization expense is projected to be $2 million in 2025.

PE Films

A summary of results for PE Films is provided below:

Year Ended Favorable/

(In thousands, except percentages) December 31, (Unfavorable)

Net sales in 2024 increased 37.0% versus 2023 due to higher net sales in Surface Protection. Sales volume in 2024 for surface protection films increased 57% versus 2023, with extremely high sales volumes in the first half of 2024 associated with the restocking of Surface Protection customers’ inventories. Overwrap films volume increased 14% versus 2023, primarily due to volume increases associated with lower margin business.

EBITDA from ongoing operations in 2024 increased $19.3 million versus 2023 primarily due to:

•Higher contribution margin of $19.0 million resulting from:

◦A $19.4 million increase from Surface Protection associated with substantially higher volume and favorable pricing ($13.4 million), and operating efficiencies and variable cost savings ($6.0 million);

◦Relatively flat contribution margin from overwrap films, associated with a shift in sales mix and unfavorable pricing ($1.0 million), offset by operating efficiencies and variable cost savings ($1.0 million); and

◦The pass-through lag associated with resin costs ($1.0 million charge in 2024 versus a charge of $0.5 million in 2023).

19

•Inventories accounted for under the LIFO method that resulted in a benefit of $0.2 million in 2024 versus a benefit of $1.3 million in 2023.

•Lower SG&A of $0.9 million primarily due to decreased research and development costs ($1.6 million), partially offset by increased employee-related incentive compensation ($1.2 million).

See discussion of quantitative and qualitative disclosures about market risk in Item 7A in this Form 10-K for additional information on resin price trends.

Projected Capital Expenditures and Depreciation & Amortization

Capital expenditures for PE Films are projected to be $3 million in 2025, including $2 million for productivity projects and $1 million for capital expenditures required to support continuity of current operations. Depreciation expense is projected to be $5 million in 2025. There is no amortization expense for PE Films.

Corporate Expenses and Interest

Corporate expenses, net in 2024 decreased by $9.2 million compared to 2023, primarily due to lower pension expense as a result of the pension plan termination completed in 2023 ($10.7 million), a non-recurring charge in 2023 associated with the pension plan transition ($2.3 million) and lower software maintenance fees ($0.6 million), partially offset by higher employee-related incentive compensation ($4.7 million).

Interest expense was $4.7 million in 2024 in comparison to $6.3 million in 2023, primarily due to lower weighted average total debt outstanding, partially offset by higher interest rates.

2023 versus 2022

Aluminum Extrusions

A summary of results for Aluminum Extrusions is provided below:

Year Ended Favorable/

(In thousands, except percentages) December 31, (Unfavorable)

Net sales in 2023 decreased 25.6% versus 2022 primarily due to lower sales volume and the pass-through of lower metal costs.

EBITDA from ongoing operations decreased $28.8 million in 2023 versus 2022, primarily due to:

•A 25.0 million decrease in contribution margin associated with:

◦Lower volume ($27.6 million), lower labor productivity in the first half of 2023 ($0.9 million), higher supply expense, including higher paint expense associated with a shift to more painted product throughout 2023 and inflationary costs for other supplies ($1.6 million), partially offset by lower utility costs ($2.3 million);

◦The timing of the flow-through under the FIFO method of aluminum raw material costs, which were previously acquired in a quickly changing commodity pricing environment, causing a temporary mismatch in

the change in the cost of raw materials included in variable costs and the pass through to customers included in sales, resulted in a charge of $1.0 million in 2023 versus a benefit of $0.1 million in 2022; and

•Inventories accounted for under the LIFO method resulted in a benefit of $0.9 million in 2023 versus a benefit of $5.4 million in 2022.

•Lower manufacturing fixed costs of $2.0 million primarily due to lower non-production utility costs ($0.9 million) and lower employee-related compensation ($0.5 million). In addition, the Company recorded an unfavorable out-of-period adjustment of $0.4 million related to inventory and accrued labor costs in 2022.

•Lower SG&A expenses of $1.9 million primarily due to lower employee incentive-based compensation ($2.5 million) and lower expense for allowance for bad debt ($0.8 million), partially offset by other employee-related compensation ($0.9 million) and increased information technology expenses ($0.4 million).

PE Films

A summary of results for PE Films is provided below:

Year Ended Favorable/

(In thousands, except percentages) December 31, (Unfavorable)

LIFO inventory adjustment (1,333) 521 NM*

Net sales in 2023 decreased 21.3% versus 2022, primarily due to lower volume in Surface Protection, resulting from weak demand in the consumer electronics market and customer inventory corrections during 2023. Sales volume in 2023 for surface protection films declined 22% and increased 2% for overwrap films versus 2022.

EBITDA from ongoing operations in 2023 decreased $0.7 million versus 2022 primarily due to:

•Lower contribution margin of $5.5 million resulting from:

◦An $8.6 million decrease from Surface Protection associated with a market slowdown and customers’ inventory corrections ($11.1 million) and for previously disclosed customer product transitions ($0.7 million), partially offset by favorable pricing ($0.5 million) and operating efficiencies ($2.6 million);

◦A $4.5 million increase from overwrap films associated with higher volume, favorable mix and favorable pricing ($1.3 million) and operating efficiencies and cost improvements ($3.2 million); and

◦The pass-through lag associated with resin costs (a charge of $0.5 million in 2023 versus a benefit of $0.9 million in 2022).

•Inventories accounted for under the LIFO method, which resulted in a benefit of $1.3 million versus a charge of $0.5 million in 2022;

•Lower fixed manufacturing costs of $1.4 million primarily due to employee compensation expenses ($1.0 million) and other fixed cost savings ($0.2 million).

•Lower SG&A of $2.0 million primarily due to lower research and development ($2.0 million) from the closure of the technical center in Richmond, VA.

21

Corporate Expenses and Interest

Corporate expenses, net in 2023 decreased by $6.7 million compared to 2022, primarily due to lower pension expense as a result of the pension plan termination completed in 2023 ($3.7 million), lower accruals for employee-related compensation ($2.1 million), lower stock-based compensation ($1.3 million), lower professional fees associated with business development activities ($0.8 million), and lower external and internal audit fees ($1.0 million), partially offset by a charge to adjust the initial purchase price of the nonparticipating single premium group annuity contract as a result of the routine administrative process to transition the pension plan ($2.0 million).

Interest expense was $6.3 million in 2023 in comparison to $4.1 million in 2022, primarily due to higher weighted average total debt outstanding and higher interest rates.

Liquidity and Capital Resources

The Company continues to focus on working capital management. Measures such as days sales outstanding (“DSO”), days inventory outstanding (“DIO”) and days payables outstanding (“DPO”) are used to evaluate changes in working capital. Changes in operating assets and liabilities from December 31, 2023 to December 31, 2024 are summarized below. Cash flows for discontinued operations have not been separately disclosed in the consolidated statements of cash flows.

•Accounts and other receivables increased $9.2 million or 16.5%.

◦Accounts and other receivables in Aluminum Extrusions increased $8.3 million primarily due to higher sales volume and the pass-through of higher metal costs, partially offset by a lower average conversion price add-on to metal costs associated with a shift in sales mix in the fourth quarter of 2024 versus the fourth quarter of 2023. DSO (computed using trailing 12 months net sales and a rolling 12-month average of accounts and other receivables balances) was approximately 44.7 days in 2024 and 45.1 days in 2023.

◦Accounts and other receivables in PE Films increased $0.9 million primarily due to higher sales volume in surface protection films. DSO was approximately 24.9 days in 2024 and 26.3 days in 2023.

•Inventories increased $1.7 million or 3.5%.

◦Inventories in Aluminum Extrusions remained consistent with prior year. DIO (computed using trailing 12 months costs of goods sold calculated on a FIFO basis and a rolling 12-month average of inventory balances calculated on the FIFO basis) was approximately 47.4 days in 2024 and 51.6 days in 2023.

◦Inventories in PE Films increased $1.4 million due to higher raw materials costs and higher finished goods. The DIO was approximately 50.3 days in 2024 and 57.2 days in 2023.

•Net property, plant and equipment decreased by $14.1 million or 9.3% primarily due to depreciation expense ($21.4 million), partially offset by capital expenditures ($8.3 million).

•Identifiable intangible assets, net decreased by $1.8 million or 19.5% primarily due to amortization expense.

•Deferred income tax assets, net increased $9.3 million or 40.1% primarily due to an increase in tax credit carryforwards offset by the utilization of net operating loss and interest limitation carryforwards. Deferred tax liabilities related to intangible amortization, depreciation and foregone tax credits on foreign branch income decreased $6.3 million while deferred taxes assets related to capitalized R&D and asset write-offs, divestitures and environmental accruals increased $4.3 million. See Note 11 “Income Taxes” to the Consolidated Financial Statements in Item 15 for additional information.

•Accounts payable decreased by $4.6 million or 6.7%.

◦Accounts payable in Aluminum Extrusions decreased $3.9 million, primarily due to the timing of payments. DPO (computed using trailing 12 months costs of goods sold calculated on a FIFO basis and a rolling 12-month average of accounts payable balances) was approximately 44.5 days in 2024 and 49.8 days in 2023.

◦Accounts payable in PE Films remained relatively flat. The DPO was approximately 41.3 days in 2024 and 43.4 days for 2023.

Net cash provided by operating activities was $25.5 million in 2024 compared to net cash provided by operating activities of $24.0 million in 2023. The change in operating activities is primarily due to an increase in EBITDA from ongoing operations of the Company’s continuing business segments of $22.7 million, partially offset by a net increase in accounts and other receivables, inventories, prepaid expenses and other, and accounts payable of $18.9 million.

Net cash provided by investing activities was $40.5 million in 2024 compared to net cash used in investing activities of $26.2 million in 2023. The change in investing activities is primarily due to net cash proceeds received for the sale of Terphane ($54.6 million) and lower capital expenditure spending ($12.1 million).

Net cash used in financing activities was $65.0 million in 2024 compared to net cash used in financing activities of $4.5 million in 2023. The change in financing activities is primarily due to higher debt principal payments, net of borrowings ($72.8 million) under the ABL Facility (as defined below), lower dividends paid ($8.9 million) and lower debt financing fees ($3.4 million).

At December 31, 2024, Tredegar had cash, cash equivalents and restricted cash of $7.1 million, including funds held in locations outside the U.S. of $1.6 million.

23

Debt and Credit Agreements

ABL Facility

In December 2023, the Company entered into Amendment No. 3 to the Second Amended and Restated Credit Agreement (“the Credit Agreement”), which, prior to the ABL Adjustment Date (as defined below), provided the Company with a $180 million senior secured asset-based revolving credit facility. In April 2024, the Company entered into Amendment No. 4 to the Credit Agreement (as amended by Amendment No. 3 and Amendment No. 4, the “ABL Facility”) that, among other items: (i) moved the ABL Adjustment Date (defined below) from March 31, 2025 to September 30, 2025 and (ii) required weekly reporting of the borrowing base financial covenant until the ABL Adjustment Date. The ABL Facility is secured by substantially all assets of the Company and its domestic subsidiaries, including equity in certain material first-tier foreign subsidiaries. Availability for borrowings under the ABL Facility is governed by a borrowing base, determined by the application of specified advance rates against eligible assets, including a portion of trade accounts receivable, inventory, cash and cash equivalents, owned real properties, and owned machinery and equipment. Upon the earlier of September 30, 2025 or the date the Company received the proceeds from the sale of Terphane (the “ABL Adjustment Date”), the $180 million ABL Facility was to be reduced to $125 million. On November 1, 2024, with the closing of the sale of Terphane, the ABL Adjustment Date occurred. The ABL Facility will expire on June 30, 2026.

The financial covenant is a minimum fixed charge coverage ratio (as defined in the ABL Facility) of 1.00:1.00 that will be triggered in the event that availability is less than 10% of the $125 million commitment amount and continuing thereafter until availability is greater than 10% of the $125 million commitment amount for 30 consecutive days. As of December 31, 2024, funds available to borrow under the ABL Facility was $43.8 million, or 35.0% of the aggregate commitment of $125 million.

PE Films Guangzhou Loan

In June 2024, PE Films' business location in Guangzhou, China, Guangzhou Tredegar Film Products Co., Ltd.(“Guangzhou Tredegar”), entered into a 9.5 million Chinese Yuan, which is equivalent to $1.3 million as of December 31, 2024, revolving loan with the Industrial and Commercial Bank of China. The loan matures on July 3, 2025. The interest rate is the one-year loan prime rate published by the National Interbank Funding Center for the working day immediately preceding the drawdown date, minus 0.45%. As of December 31, 2024, the National Interbank Funding Center rate was 3.45%. The

25

revolving loan is secured by a mortgage contract listing the Guangzhou Tredegar factory building as collateral. The mortgage contract has a maximum value of 30 million Chinese Yuan and is effective from June 25, 2024 through May 31, 2027. This loan was presented as current debt on the consolidated balance sheet for the year ended December 31, 2024.

For more information on the ABL Facility and the PE Films Guangzhou Loan, see Note 7 “Debt and Credit Agreements” to the consolidated Financial Statements in Item 15.

The Company believes that existing borrowing availability, current cash balances and cash flow from operations will be sufficient to satisfy short term material cash requirements related to working capital, capital expenditure, and debt repayments for at least the next 12 months. In the longer term, liquidity will depend on many factors, including the results of operations, the timing and extent of capital expenditures, changes in operating plans, or other events that would cause the Company to seek additional financing in future periods.

Material Cash Requirements for Known Contractual and Other Obligations

The Company’s material cash requirements from known contractual and other obligations as of December 31, 2024 were as follows:

Debt and interest payments

As of December 31, 2024, the Company had outstanding debt under the ABL Facility of $60.6 million with contractual payments due in June 2026. Estimated future interest payments associated with the ABL Facility total $6.6 million, with $4.4 million payable within the next 12 months.

As of December 31, 2024, PE Films had outstanding debt of $1.3 million under the PE Films Guangzhou Loan. Estimated future interest payments associated with the PE Films Guangzhou Loan payable within the next 12 months were immaterial.

Capital expenditure commitments

See “Projected Capital Expenditures and Depreciation & Amortization” within “Segment Operations Overview” above in this Item 7 for discussion of the Company’s planned investment in capital expenditures in 2024, of which $0.4 million are contractual commitments that existed as of December 31, 2024.

Operating Leases

The Company enters into various operating leases primarily for real estate, office equipment and vehicles. See Note 4 “Leases” to the Consolidated Financial Statements in Item 15 for additional information.

Uncertain Tax Positions

As of December 31, 2024, unrecognized tax benefits on uncertain tax positions were $0.8 million. Tax payments resulting from the successful challenge by the taxing authority on uncertain tax positions taken by Tredegar would possibly result in the payment of interest and penalties of $0.2 million, which were accrued at December 31, 2024, if tax payments were made as a result of a successful challenge by the taxing authority on uncertain tax positions. Due to uncertainties in the timing of potential tax audits, the timing of the resolution of these positions is uncertain. Therefore, the Company is unable to make a reasonably reliable estimate of the timing of payments beyond 12 months. See Note 11 “Income Taxes” to the Consolidated Financial Statements in Item 15 for additional information.

Off-Balance Sheet Arrangements

The Company has no material off-balance sheet arrangements that have had or are reasonably likely to have a material current or future effect on its financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.

From time to time, the Company enters into transactions with third parties in connection with the sale of assets or businesses in which it agrees to indemnify the buyers or third parties involved in the transaction, or the sellers or third parties involved in the transaction agree to indemnify Tredegar, for certain liabilities or risks related to the assets or business. Also, in the ordinary course of business, the Company may enter into agreements with third parties for the sale of goods or services that may contain indemnification provisions. In the event that an indemnification claim is asserted, liability for indemnification would be subject to an assessment of the underlying facts and circumstances under the terms of the applicable agreement. Further, any indemnification payments may be limited or barred by a monetary cap, a time limitation, or a deductible or basket. For these reasons, the Company is unable to estimate the maximum potential amount of the potential future liability under the indemnity provisions of these agreements. Tredegar does, however, accrue for losses for any known contingent liability, including those that may arise from indemnification provisions, when future payment is probable and the amount is reasonably estimable. The Company discloses contingent liabilities if the probability of loss is reasonably possible and material.

Critical Accounting Policies and Estimates

The preparation of financial statements in accordance with GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures. Certain accounting policies, as described below, are considered "critical accounting policies" because they are particularly dependent on estimates made by management about matters that are inherently uncertain and could have a material impact on the Company’s consolidated financial statements. Estimates and judgments are based on historical experience, forecasted events and various other assumptions that management believes are reasonable under the circumstances. Actual results could differ significantly from those estimates under different assumptions and conditions. A summary of all of our significant accounting policies is included in Note 1 “Nature of Operations and Summary of Significant Accounting Policies” to the Consolidated Financial Statements in Item 15.

Impairment of Goodwill

The Company assesses goodwill for impairment when events or circumstances indicate that the carrying value may not be recoverable, or, at a minimum, on an annual basis (December 1st of each year). When assessing goodwill for impairment, accounting guidance allows the Company to first perform a qualitative assessment (“Step 0 analysis”), which evaluates certain qualitative factors, including macroeconomic conditions, industry and market considerations, cost factors and overall financial performance, as well as company and reporting unit factors. If the Company's Step 0 analysis indicates that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, then the Company would perform a quantitative impairment test (“Step 1 analysis”).

Domestic producers of aluminum extrusions in the U.S. continue to experience adverse conditions associated with economic uncertainty, including persistently high interest rates, tight lending standards and inflationary pressures, which negatively impact the non-residential B&C end-use market. These pandemic-related disruptions, which resulted in long lead times and a decline in industry capacity utilization, caused pricing pressure in the aluminum extrusions end-use markets. An influx of foreign imports at less-than-fair value pricing has also adversely impacted domestic producers.

During 2024, customers of the Aluminum Extrusions’ Clearfield, Utah operation ("Clearfield") acquired as “Futura” in February 2017 continued to seek supply from other sources to meet their demand, including imports. However, in 2024, Clearfield continued to experience a resurgence in customer volumes that had declined due to the pandemic, albeit not at the speed and profit level that was previously projected. The recovery has been slower than previously anticipated, and is not trending back to previous Company expectations to replicate the EBITDA and net cash flow generation that existed prior to the pandemic-related disruptions and influx of imports.

As a consequence, the Company performed a goodwill impairment analysis during the fourth quarter of 2024 using Clearfield projections that assume the continuation of lower margin business. Since the estimated fair value of Clearfield fell below its carrying value by more than the amount of goodwill, the Company recognized a non-cash write-off of goodwill of $13.3 million ($10.4 million after deferred income tax benefits) associated with Clearfield.

The Company estimated the fair value of Clearfield by: (i) computing an estimated enterprise value (“EV”) utilizing the discounted cash flow method (the “DCF Method”), and (ii) adding cash and cash equivalents. Key financial assumptions utilized to determine the fair value of the reporting unit include sales volume and sales price growth projections. At December 31, 2024, the effect of a two percent increase per year in these growth projections would increase the reporting unit’s fair value, however such sensitized fair value is still below Clearfield’s carrying value by more than the amount of goodwill.

As of December 31, 2024, the Company’s remaining goodwill of $22.4 million was included in the Surface Protection reporting unit. See Note 1 “Nature of Operations and Summary of Significant Accounting Policies” to the Consolidated Financial Statements in Item 15 for additional information on the analysis of goodwill impairment.

Income Taxes

Current tax liabilities and assets are recognized for the estimated taxes payable or refundable, respectively, on the tax returns for the current year. Deferred tax assets and liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. Accordingly, accounting for income taxes represents the Company’s best estimate of various events and transactions. Tax laws are often complex and may be subject to differing interpretations by the taxpayer and the relevant governmental taxing authorities. In establishing a provision for income tax expense, Tredegar must make judgments and interpretations about the application of tax laws. The Company must also make estimates about when in the future certain items will affect taxable income in the various taxing jurisdictions.

A valuation allowance is recorded in the period when the Company determines that it is more likely than not that all or a portion of deferred income tax assets may not be realized. The establishment and removal of a valuation allowance requires the Company to consider all positive and negative evidence and make a judgmental decision regarding the amount of valuation allowance required as of a reporting date.

27

Tredegar may be required to change its provision for income taxes when estimates used in determining valuation allowances on deferred tax assets significantly change, or when new information indicates the need for adjustment in valuation allowances. Additionally, future events, such as changes in tax laws, tax regulations, or interpretations of such laws or regulations, could have an impact on the provision for income tax and the effective tax rate. Any such changes could significantly affect the amounts reported in the financial statements in the year these changes occur.

See Note 11 “Income Taxes” to the Consolidated Financial Statements in Item 15 for additional information on income taxes.

Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Tredegar has exposure to the volatility of interest rates, polyethylene resin prices, aluminum ingot and scrap prices, energy prices, foreign currencies and emerging markets. See Liquidity and Capital Resources regarding interest rate exposures related to borrowings under the ABL Facility.

Profit margins in Aluminum Extrusions are sensitive to fluctuations in aluminum ingot and scrap prices as well as natural gas prices (natural gas is the principal energy source used to operate its casting furnaces). Changes in polyethylene resin prices and the timing of those changes could have a significant impact on profit margins in PE Films. There is no assurance of the Company’s ability to pass through higher raw material and energy costs to its customers.

The purchase price of raw materials fluctuates on a monthly basis; therefore, Aluminum Extrusions pricing policies generally allow the Company to pass the underlying index cost of aluminum and certain alloys through to the vast majority of our customers so that we remain substantially neutral to metal pricing. In the normal course of business, Aluminum Extrusions enters into fixed-price forward sales contracts with certain customers for the sale of fixed quantities of aluminum extrusions at scheduled intervals. In order to hedge its exposure to aluminum price volatility (see the chart below) under these fixed-price arrangements, which generally have a duration of not more than 12 months, the Company enters into a combination of forward purchase commitments and futures contracts to acquire or hedge aluminum, based on the scheduled deliveries. See Note 9 “Derivatives” to the Consolidated Financial Statements in Item 15 for additional information.

The volatility of quarterly average aluminum prices is shown in the chart below.

28

The volatility of quarterly average natural gas prices is shown in the chart below.

The volatility of average quarterly prices of polyethylene resin in the U.S. (a primary raw material for PE Films products) is shown in the chart below:

The price of resin is driven by several factors, including supply and demand and the price of oil, ethylene and natural gas. Selling prices to customers are set considering numerous factors, including the expected volatility of resin prices. In certain situations, PE Films has index-based pass-through raw material cost arrangements with customers. However, under certain agreements, changes in resin prices are not passed through for a period of 90 days or more. In response to unprecedented cost increases and supply issues for polyethylene and polypropylene resin, Tredegar Surface Protection implemented a quarterly resin cost pass-through mechanism, effective July 1, 2021, for all products and customers not previously covered by such arrangements. Pricing on the remainder of the business is based upon raw material costs and supply/demand dynamics within the markets in which the Company competes.

29

The Company sells to customers in foreign markets through its foreign operations and through exports from U.S. plants. The percentage of sales and total assets for manufacturing operations related to foreign markets for 2024, 2023 and 2022 are as follows:

Net Sales Net Sales Net Sales

Canada 2 — — 2 — — 1 — —

Latin America 1 — — 1 — — 1 — —

Tredegar attempts to match the pricing and cost of its products in the same currency and generally views the volatility of foreign currencies and the corresponding impact on earnings and cash flow as part of the overall risk of operating in a global environment (for additional information, see trends for the Chinese Yuan in the chart below). Exports from the U.S. are generally denominated in U.S. Dollars. The Company’s foreign currency exposure on income from continuing foreign operations relates to the Chinese Yuan.

PE Films is generally able to match the currency of its sales and costs for its product lines. Tredegar estimates that the change in the value of foreign currencies relative to the U.S. Dollar on PE Films had an unfavorable impact on EBITDA from ongoing operations in PE Films of $0.1 million in 2024 compared to 2023.

Trends for the Chinese Yuan are shown in the chart below:

Tredegar Corporation:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Tredegar Corporation and subsidiaries (the Company) as of December 31, 2024 and 2023, the related consolidated statements of income (loss), comprehensive income (loss), cash flows, and shareholders’ equity for each of the years in the three-year period ended December 31, 2024, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2024, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated March 12, 2025 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Sufficiency of audit evidence over sales

As discussed in Notes 1 and 12 to the consolidated financial statements, the Company recorded approximately $598,025 thousand of sales during the year ended December 31, 2024. Sales are recognized by the sale of finished products to customers. Those sales predominantly contain a single performance obligation and revenue is recognized at the point in time when control of the product is transferred to customers, along with the title, risk of loss and rewards of ownership. Depending on the arrangement with the customer, these criteria are met either at the time the product is shipped or when the product is made available or delivered to the destination specified in the agreement with the customer. The processing and recording of sales is decentralized across multiple locations and is reliant on multiple information technology (IT) systems.

We identified the evaluation of the sufficiency of audit evidence over sales as a critical audit matter. Subjective auditor judgment was required to determine the nature and extent of procedures to be performed over the Company’s locations because of the number of IT applications, the decentralized nature of the sales generating activities, and the need to involve IT professionals with specialized skills and knowledge.

35

The following are the primary procedures we performed to address this critical audit matter. We applied auditor judgment to determine the nature and extent of procedures to be performed over sales, including determining the locations at which those procedures were to be performed. For each location where procedures were performed, we evaluated the design and tested the operating effectiveness of certain internal controls over the Company’s revenue recognition processes, including the controls over the accurate recording of revenue transactions. We involved IT professionals with specialized skills and knowledge, who assisted in testing certain general IT controls and application controls, including IT system-generated reports used by the Company in its revenue recognition processes. At certain locations, we selected a sample of transactions and compared the amounts recognized to relevant cash receipts as well as underlying documentation such as contracts, purchase orders, shipping documents, or other third-party evidence. At certain locations, we performed software-assisted data analysis to test relationships among certain revenue transactions. At the locations we performed software-assisted data analysis, we also tested certain transactions and compared the amounts recognized by the Company to relevant cash receipts as well as underlying documentation such as contracts, purchase orders, shipping documents, or other third-party evidence. We evaluated the sufficiency of audit evidence obtained by assessing the results of procedures performed, including the appropriateness of the nature and extent of such evidence.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors

Tredegar Corporation:

Opinion on Internal Control Over Financial Reporting

We have audited Tredegar Corporation and subsidiaries' (the Company) internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2024 and 2023, the related consolidated statements of income (loss), comprehensive income (loss), cash flows, and shareholders’ equity for each of the years in the three-year period ended December 31, 2024, and the related notes (collectively, the consolidated financial statements), and our report dated March 12, 2025 expressed an unqualified opinion on those consolidated financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

NOTES TO FINANCIAL STATEMENTS

Tredegar Corporation and Subsidiaries

1. NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations. Tredegar Corporation and subsidiaries (collectively “Tredegar,” “the Company,” “we,” “us” or “our”) is an industrial manufacturer with two primary businesses: custom aluminum extrusions for the North American building & construction, automotive and specialty end-use markets; and surface protection films for high-technology applications in the global electronics industry and polyethylene overwrap films used for bathroom tissue and paper towels. The Company’s business segments are Aluminum Extrusions (also referred to as Bonnell Aluminum) and PE Films. More information on the Company’s business segments is provided in Note 12.

On November 1, 2024, the Company completed the sale of its flexible packaging films business (also referred to as “Terphane”) headquartered in Brazil to Oben Group (“Oben”). Commencing in the fourth quarter of 2024, all historical results for Terphane have been presented as discontinued operations. For more information on this transaction, see Note 16.

Basis of Presentation and Principles of Consolidation. The consolidated financial statements include the accounts and operations of the Company and have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). Intercompany balances and transactions have been eliminated in consolidation. Certain amounts for the prior years have been reclassified to conform to current year presentation.

Fiscal Year End. The Company operates on a calendar fiscal year except for the Aluminum Extrusions segment, which operates on a 52/53-week fiscal year basis. References to Aluminum Extrusions for 2024, 2023 and 2022 relate to the 52-week fiscal year ended December 29, 2024, 53-week fiscal year ended December 31, 2023 and 52-week fiscal year ended December 25, 2022, respectively. The Company does not believe the impact of reporting the results of this segment in this manner is material to the consolidated financial results. The Company may fund or receive cash from the Aluminum Extrusions segment based on Aluminum Extrusion’s cash flows from operations during the intervening period from Aluminum Extrusion’s fiscal year end to the Company’s calendar year end. As a result, the Company’s cash and cash equivalents declined by $3.6 million as of December 31, 2024 since the Company made payments to the Aluminum Extrusions segment to fund its working capital during the intervening period.

Use of Estimates. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses and disclosure of contingent assets and liabilities (if any). On an ongoing basis, the Company evaluates its estimates, including those related to provisions for transaction and credit losses, income taxes, pension, and the valuation of goodwill and intangible assets, among others. Tredegar bases its estimates on historical experience and various other assumptions which the Company believes to be reasonable under the circumstances. Actual results could differ from those estimates.

Foreign Currency Translation. The financial statements of subsidiaries located outside the U.S., where the local currency is the functional currency, are translated into U.S. Dollars using exchange rates in effect at the period end for assets and liabilities and average exchange rates during each reporting period for results of operations. Adjustments resulting from the translation of these financial statements are reflected as a separate component of shareholders’ equity. There are no operating subsidiaries located outside the U.S. where the U.S. Dollar is the functional currency. Transaction and remeasurement gains or losses included in income were losses of $0.3 million, $0.2 million and $0.8 million in 2024, 2023 and 2022, respectively.

Cash, Cash Equivalents and Restricted cash. Cash, cash equivalents and restricted cash consist of cash on hand in excess of daily operating requirements and highly liquid investments with original maturities of three months or less. At December 31, 2024 and 2023, Tredegar had cash, cash equivalents and restricted cash of $7.1 million and $13.1 million, respectively, including funds held in locations outside the U.S. of $1.6 million and $0.8 million, respectively.

The Company’s policy permits investment of excess cash in marketable securities that have the highest credit ratings and maturities of less than one year. The primary objectives of the policy are safety of principal and liquidity.

The following table provides a reconciliation of cash, cash equivalents and restricted cash to amounts shown in the consolidated statements of cash flows:

December 31, December 31,

Cash and cash equivalents $ 7,062 $ 9,660

Restricted cash — 3,391

Total cash, cash equivalents and restricted cash $ 7,062 $ 13,051

43

Restricted cash as of December 31, 2023 consists of $3.4 million of receipts that have not yet been applied to the ABL Facility (defined below). See Note 7 for additional information.

Accounts and Other Receivables, net. Accounts receivables are stated at the amount invoiced to customers less allowances for doubtful accounts. Accounts receivables are non-interest bearing and arise from the sale of products to customers under typical industry trade terms. Notes receivables are immaterial. Past due amounts are determined based on established terms and charged-off when deemed uncollectible. The allowance for doubtful accounts is determined based on an assessment of probable losses taking into account past due amounts, customer credit profile, historical experience and current economic conditions. For receivables that do not have a specific allowance, the loss rate is computed by segment to apply to the remaining receivables balance, using each segment’s historic loss rate. Other receivables include value-added taxes related to certain foreign subsidiaries and other miscellaneous receivables due within one year. For certain customers, the Company has arrangements in place with financial institutions whereby certain customer receivables are sold to the financial institution at a discount and without recourse. Upon sale, the associated receivable is unrecognized, and the discount is recognized. For more information on accounts and other receivables, net, see Note 2.

Inventories. Inventories are stated at the lower of cost or market, with cost determined using the last in, first out (“LIFO”) method, the weighted average cost or the first in, first out (“FIFO”) method. Cost elements included in work-in-process and finished goods inventories are raw materials, direct labor and manufacturing overhead. Finished goods, work-in-process, raw materials and supplies, stores and other inventory are reviewed to determine if inventory quantities are in excess of forecasted usage or if they have become obsolete.

Property, Plant and Equipment. Accounts include costs of assets constructed or purchased, related delivery and installation costs and interest incurred on significant capital projects during their construction periods. Expenditures for renewals and betterments also are capitalized, but expenditures for repairs and maintenance are expensed as incurred. The cost and accumulated depreciation applicable to assets retired or sold are removed from the respective accounts, and gains or losses thereon are included in income. Capital expenditures for property, plant and equipment include capitalized interest. Capitalized interest included in capital expenditures for property, plant and equipment was immaterial. Depreciation is computed primarily by the straight-line method based on the estimated useful lives of the assets that generally range from 5 to 40 years for buildings and land improvements and 2 to 20 years for machinery and equipment.

Goodwill and Identifiable Intangibles. The excess of the purchase price over the fair value of identifiable net assets of acquired companies is allocated to goodwill. The Company assesses goodwill for impairment when events or circumstances indicate that the carrying value may not be recoverable, or, at a minimum, on an annual basis (December 1st of each year). When assessing goodwill for impairment, accounting guidance allows the Company to first perform a qualitative assessment (“Step 0 analysis”), which evaluates certain qualitative factors, including macroeconomic conditions, industry and market considerations, cost factors and overall financial performance, as well as company and reporting unit factors. If the Company's Step 0 analysis indicates that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, then the Company would perform a quantitative impairment test (“Step 1 analysis”).

Domestic producers of aluminum extrusions in the U.S. continue to experience adverse conditions associated with economic uncertainty, including persistently high interest rates, tight lending standards and inflationary pressures, which negatively impact the non-residential B&C end-use market. These pandemic-related disruptions, which resulted in long lead times and a decline in industry capacity utilization, caused pricing pressure in the aluminum extrusions end-use markets. An influx of foreign imports at less-than-fair value pricing has also adversely impacted domestic producers.

During 2024, customers of the Aluminum Extrusions’ Clearfield, Utah operation ("Clearfield") acquired as “Futura” in February 2017 continued to seek supply from other sources to meet their demand, including imports. However, in 2024, Clearfield continued to experience a resurgence in customer volumes that had declined due to the pandemic, albeit not at the speed and profit level that was previously projected. The recovery has been slower than previously anticipated, and is not trending back to previous Company expectations to replicate the EBITDA and net cash flow generation that existed prior to the pandemic-related disruptions and influx of imports.

As a consequence, the Company performed a goodwill impairment analysis during the fourth quarter of 2024 using Clearfield projections that assume the continuation of lower margin business. Since the estimated fair value of Clearfield fell below its carrying value by more than the amount of goodwill, the Company recognized a non-cash write-off of goodwill of $13.3 million ($10.4 million after deferred income tax benefits) associated with Clearfield.
