Other Developments

Aligned to Dow’s previously announced strategic review of select assets in Europe, Consumer Solutions will shut down its basics siloxanes operations in Barry, United Kingdom, by mid-year 2026. The shutdown will right-size regional capacity, reduce merchant sales exposure, and remove higher cost, energy intensive portions of Dow's portfolio in the region. This will also improve the Company’s ability to supply profitable derivative demand and optimize margins.

CORPORATE

Corporate includes certain enterprise and governance activities (including insurance operations, environmental operations, etc.); non-business aligned joint ventures; non-business aligned litigation expenses; and discontinued or non-aligned businesses.

RAW MATERIALS

The Company operates in an integrated manufacturing environment. Basic raw materials are processed through many stages to produce a number of products that are sold as finished goods at various points in those processes. Hydrocarbon-based raw materials are the major raw material streams that feed the production of the Company's finished goods. The Company purchases hydrocarbon-based raw materials including ethane, propane, butane, naphtha and condensate as feedstocks. These raw materials are used in the production of both saleable products and energy. The Company also purchases and sells certain monomers, primarily ethylene and propylene, to balance internal production and internal consumption. The Company purchases natural gas, primarily to generate electricity, and purchases electric power to supplement internal generation. In addition, the Company produces a portion of its electricity needs in Louisiana and Texas; Alberta, Canada; The Netherlands; the United Kingdom; and Germany.

The Company's primary source of these raw materials are natural gas liquids, which are derived from natural gas and crude oil production, and naphtha, which is produced during the processing and refining of crude oil. Given recent advancements in shale gas, shale oil and conventional drilling techniques, the Company expects these raw materials to be in abundant supply. The Company's suppliers of these raw materials include regional, international and national oil and gas companies.

The Company purchases raw materials on both short- and long-term contracts. The Company had adequate supplies of raw materials in 2025 and expects to continue to have adequate supplies of raw materials in 2026.

COMMITMENT TO SUSTAINABILITY

Dow is actively aligning its business and sustainability strategy, operational footprint, product offerings and technologies to unlock new sustainable growth opportunities within the markets it serves and create value growth for its shareholders.

The following four areas are critical for Dow to consistently deliver responsible, best-in-class performance and value growth:

Protecting the Climate

Climate change is a critical challenge to the world and Dow’s business. Dow embraces its responsibility to help reduce global GHG emissions and the impacts of climate change on natural ecosystems. Dow takes a holistic approach to climate protection, considering air, water and land and includes efforts to both mitigate and adapt to climate change.

For decades, Dow has been reducing GHG emissions in its operations. Dow's detailed investment plan and roadmap outlines a clear decarbonization “Path2Zero” while driving value growth. Dow has been a leader in water stewardship for more than 30 years and is now focused on water resilience in the watersheds on which its top sites rely. Dow pioneered the methodology to value nature in business decisions over the last 10 years, and the next chapter in its biodiversity and nature strategy is to partner with leading organizations like Ducks Unlimited to conserve 50,000 acres of habitat by 2050.

Advancing a Circular Economy and Safer Materials

Transitioning to a circular economy is vital to a sustainable future and materials science plays a critical role. Dow is helping advance a circular economy by transforming the way materials are made, used and reused. As Dow develops technologies, it considers the total life cycle of a product, including factors such as demand on natural resources, GHG emissions, performance, longevity and end-of-life options. Dow strives to extend the purposeful life of materials, retaining their value for as long as possible.

Dow is also focused on utilizing its strong innovation pipeline to develop safer materials or reduce or eliminate priority substances in its products. The Company invests in upstream manufacturing technologies to reduce facility emissions and, where necessary, restricts downstream uses of some substances.

Cultivating a Thriving Team and Community

The safety of Dow's workforce and their communities has always been, and continues to be, the Company's top priority. Dow strives for every member of its team to return home safely each day. Furthermore, Dow understands that having people who are healthy and feel psychologically and physically safe at work helps enable the Company to be a reliable, productive company that can meet its customers’ needs.

Dow is committed to fostering a culture where people can grow and thrive in a rapidly changing world. Inclusion is core to Dow's ambition and fully aligned with its business strategy. It enables Dow to create more innovative solutions, build a more resilient workforce and supply chain, and deliver long-term value for its shareholders.

As a global leader in materials science, Dow recognizes its responsibility to the communities where it does business, and Dow continues to drive a culture that fosters caring about its people, its communities and its environment. Dow is committed to building an innovative, inclusive and more sustainable future; one where communities thrive; everyone has equitable access to science, technology, engineering and math ("STEM") and skilled trades careers; and employees are empowered to accelerate positive social change through volunteerism. Guided by the passion of its people, powerful partnerships and a commitment to making an impact, Dow focuses on creating positive and enduring change in its communities.

Driving Accountability and Best-in-Class Performance

Dow exercises strong corporate governance through transparency, risk management, effective leadership, ethical compliance and behavior, and stakeholder feedback and management. Dow’s approach to corporate governance is centered on its core values and helps create and maintain a culture that supports long-term success, strengthens decision-making and builds trust in the Company. Key areas include the depth and range of experiences of Dow's Board of Directors, stakeholder engagement, enterprise risk management, compensation practices, and ethics and compliance programs. By focusing on these areas, Dow aims to enhance transparency, foster a culture of integrity and align with shareholder interests.

HUMAN CAPITAL

Dow’s ambition – to be the most innovative, customer-centric, inclusive and sustainable materials science company in the world – starts with people. Dow employees create innovative and sustainable materials science solutions to advance the world. Every answer starts with asking the right questions, which is why the diverse, dedicated Dow team collaborates with customers and other stakeholders to find solutions to the world's toughest challenges. The Company's values of Respect for People, Integrity and Protecting Our Planet are fundamental beliefs that are ingrained in each action taken, can never be compromised and are the foundation of the Company's Code of Conduct.

The Company is dedicated to employee health and safety and is invested in fostering a culture of inclusion and continuous learning while supporting its employees through its Total Rewards plans and programs to ensure all Dow employees are respected, valued and encouraged to make their fullest contribution.

Safety, Employee Health and Well-Being

A commitment to safety and employee health is ingrained in Dow’s culture and central to how the Dow team works. Dow uses a comprehensive, integrated operating discipline management system that includes policies, requirements, best practices and procedures associated with health and safety. In 2025, the Company achieved an Occupational Safety and Health Administration Total Recordable Injury and Illness Rate of 0.20, based upon the number of incidents per 200,000 work hours for employees and contractors globally. This measure, along with a consistent set of globally applied, as well as locally defined, leading indicators of safety performance, are cornerstones of Dow's worker protection program. The Company maintains a robust, globally tracked near-miss program for situations that did not result in an injury, but could have been high consequence had circumstances been slightly different. This data is reviewed regularly by management and the EHS&T Committee of the Board, is visible to all employees and is built into digital dashboards that include actual injury information for every Dow location around the world.

Table of Contents

As part of the Company’s total worker health strategy, employees have access to occupational health services at no cost through on-site, Company-managed clinics at its manufacturing locations or an offsite provider overseen by Dow Occupational Health. In addition to access for occupational health needs, the Company also has a comprehensive well-being strategy, which is framed across four dimensions – physical, mental, community and financial well-being – for an approach that is holistic, global, employee centered and outcome-driven. Key ambitions across the four dimensions focus on elements such as workplace stress, psychological safety, resiliency, workload, healthy eating and activities, and social community and inclusion opportunities.

Dow maintains active Crisis Management Teams at the corporate level and in each region where the Company operates to ensure appropriate plans are in place in the event of natural disasters or other emergencies.

Inclusion

At Dow, creating an inclusive culture that empowers every employee is a business imperative and a key pillar of the Company's ambition. A strategic and intentional focus on inclusion not only enhances the employee experience and satisfaction, but it also supports innovation, customer experience and an understanding of the communities the Company serves. In 2025, Dow earned significant recognition from Great Place to Work®, including:

•World's Best WorkplacesTM for the third consecutive year

•100 Best Companies to Work For® for the sixth consecutive year

•Ranked #1 on the Best Workplaces in Manufacturing & ProductionTM for the second consecutive year, Dow's fifth consecutive year on the list

These are significant accomplishments that represent several of the many awards the Company received related to its efforts to create a positive workplace culture.

Dow's strategic inclusion efforts are directed by its Chief Inclusion Officer and Office of Inclusion, which supports implementation throughout Dow’s businesses, functions and regions. Three Inclusion Councils drive the inclusion strategy from the top of the Company down and across the enterprise:

•The President’s Inclusion Council defines and supports Dow's inclusion strategy from the top.

•A Senior Leaders’ Inclusion Council influences change through senior and mid-level business, geographic and functional leaders.

•A Joint Inclusion Council collaborates to drive maximum employee engagement through Employee Resource Group (“ERG”) leadership.

Dow’s 10 ERGs represent a workforce rich in diversity of thought, perspectives and backgrounds. Dow’s ERGs help develop a high-performance workplace culture and cultivate a positive employee experience that improves employee satisfaction and retention. ERG participation is voluntary and open to the Company's total workforce with strong allyship representation. Senior leaders serve as executive sponsors for each ERG. In addition, Dow has a Paid Time Off Policy which provides employees time off to volunteer in the community and engage in ERG activities. In 2025, 61 percent of Dow’s workforce and 96 percent of Dow people leaders participated in at least one ERG.

Global pay disparity studies have been conducted at Dow for over 20 years to assess fair treatment between genders and between U.S. ethnic minorities and non-minorities and to ensure Dow’s pay practices are being implemented as intended. The results have been publicly disclosed within the Company's annual INtersections Report. As part of Dow’s inclusion efforts, the Company will continue to conduct annual pay gap studies and actively engage with an external partner to further develop and continue to apply best practices.

Total Rewards

To achieve Dow’s ambition, the Company invests in its people, who are at the heart of the Company, through its Total Rewards plans and programs. The Total Rewards plans and programs are structured to attract, retain and motivate Dow’s employees. Dow’s Total Rewards are designed to support all aspects of its employees – their compensation, future, health, life and career. The Company is committed to aligning its strategy and culture with the needs of its employees and optimizing the investment Dow makes in Total Rewards.

Table of Contents

As a global company with a diverse team, Dow aims to ensure employees have access to resources that allow them to meet their unique needs. That is why Dow has established three guiding principles that define its Total Rewards strategy: 1) ensuring programs are market competitive; 2) providing employees with offerings that promote their financial, mental and physical well-being; and 3) offering programs that drive a performance-oriented, results-based culture that enables long-term shareholder value creation. Dow adapts its programs for geography-specific requirements, as well as cultural standards and expectations.

Employee Engagement, Learning and Development

Throughout an employee’s career, the Company supports development through a blend of learning approaches including in-person and virtual trainings, digital learning platforms, on-the-job training and a series of leadership development programs. The Company's skills framework is aligned to enterprise competencies that support Dow's ambition. Additionally, this skills-valued focus increases the transparency of skills needed for current and future jobs and is embedded in talent practices such as goal setting, interviewing for new roles and applications for project work. This approach supports employee growth, development and skill building for evolving business needs.

Annually, all employees have the opportunity to provide feedback on employee experience and offer insights into how to improve Dow’s working culture through a global employee opinion survey. The survey covers topics such as workplace culture, leadership effectiveness, the work environment and overall employee satisfaction. In 2025, 64 percent of employees responded to the annual survey. The feedback received through this annual survey, along with occasional checkpoint surveys, is used to drive actions to improve the overall Dow experience for employees across the Company.

At December 31, 2025, the Company permanently employed approximately 34,600 people on a full-time basis.

ITEM 1A. RISK FACTORS

The factors described below represent the Company's principal risks.

CLIMATE CHANGE - RELATED RISKS

Climate Change: Climate change-related risks and uncertainties, legal or regulatory responses to climate change and failure to meet the Company’s climate change commitments could negatively impact the Company’s results of operations, financial condition and/or reputation.

The Company is subject to increasing climate-related risks and uncertainties, many of which are outside of its control. Climate change may result in more frequent and damaging severe weather and weather-related events, potential changes in precipitation patterns and extreme variability in weather patterns. These short- and long-term weather and weather-related events can disrupt the operations of the Company as well as those of its customers, partners and vendors due to damage to local infrastructure and other property damage limiting site access, and causing water scarcity and lack of access to high-quality water, among other factors. These risks and uncertainties may also directly or indirectly impact decisions to invest in the construction and/or renovation of new or existing manufacturing sites and other Company facilities and locations.

The transition to lower greenhouse gas emissions technology, the effects of carbon pricing and changes in public sentiment, incentives, regulations, taxes, public mandates or requirements and increases in climate-related lawsuits, insurance premiums and implementation of more robust disaster recovery and business continuity plans could increase costs to maintain or resume the Company’s operations or achieve its sustainability commitments in the expected timeframes, which would negatively impact the Company’s results of operations.

In 2020, the Company announced commitments to reduce its net annual Scope 1 and 2 carbon dioxide equivalent ("CO2e") emissions by an additional 5 million metric tons, approximately a 15 percent reduction compared with its 2020 baseline, by 2030 (the 2020 baseline represents a 15 percent reduction in greenhouse gas emissions since 2005) and its intention to be carbon neutral by 2050 (Scope 1+2+3, as defined by the Greenhouse Gas Protocol Corporate Accounting and Reporting Standard, plus product benefits). In November 2023, the Board approved the final investment decision to build the world's first net-zero Scope 1 and 2 CO2e emissions integrated ethylene cracker and derivatives facility in Alberta, Canada, a key element for the Company to achieve its 2030 greenhouse gas emissions reduction commitment.

The commitments reflect the Company's current plans and targets and are not guarantees that it will be able to achieve them. The execution and achievement of the Company's commitments within projected cost estimates and expected timeframes, including the success of the Company's integrated ethylene cracker and derivatives facility in Alberta, Canada, are subject to risks and uncertainties which include, but are not limited to: advancement, availability, development and affordability of technology necessary to achieve these commitments; unforeseen design, operational and technological difficulties; availability and cost of necessary materials and components; adapting products to customer preferences and customer acceptance of sustainable supply chain solutions; changes in public sentiment and political leadership, including government incentives and tax credits to promote emission reductions; the Company’s ability to comply with changing regulations, taxes, mandates or requirements related to greenhouse gas emissions or other climate-related matters, including prescriptive reporting of climate-related matters; and the Company's ability to adequately fund capital expenditures necessary to complete its planned projects. In addition, standards for tracking and reporting on sustainability matters have not been harmonized, continue to evolve and may change over time, which could result in significant revisions to the Company's performance metrics, commitments or reported progress in achieving such commitments. If the Company fails to meet its climate change commitments within the committed timeframe, coupled with its significant investments to meet those commitments, and adopt policies and practices to enhance sustainability, the Company’s reputation and its customer and other stakeholder relationships could be negatively impacted, reducing demand for the Company's products, and it may be more difficult for the Company to compete effectively or gain access to financing on acceptable terms when needed, which could negatively impact the Company’s financial condition, results of operations and cash flows.

21

Table of Contents

MACROECONOMIC RISKS

Financial Commitments and Credit Markets: Market conditions, availability of credit and changes in the Company's credit ratings could reduce the Company's flexibility to respond to changing economic and business conditions or fund capital needs and could increase borrowing costs.

The Company utilizes cash from operations and its ability to access capital markets to meet the Company's cash requirements for working capital, capital projects, debt maturities and other needs. Adverse economic conditions, a contraction in the availability of credit in the marketplace, or changes in the Company's credit ratings, including failure to maintain an investment grade rating, could increase borrowing costs and reduce sources of liquidity, restricting the Company’s flexibility to respond to changing business and economic conditions or to fund capital projects and working capital needs, which could adversely impact the Company's results of operations and liquidity.

Global Economic Considerations: The Company operates in a global, competitive environment which gives rise to operating and market risk exposure.

The Company sells its broad range of products and services in a competitive, global environment, and competes worldwide for sales on the basis of product quality, price, technology and customer service. Increased levels of competition have resulted in lower prices and lower sales volume, which have had a negative impact on the Company’s results of operations. These factors are expected to continue and may worsen in the near term, which could continue to challenge the Company's ongoing results of operations. To address these challenges amidst the ongoing macroeconomic uncertainty, the Company has taken targeted cost reduction initiatives and other actions to advance its balanced capital allocation approach and enhance financial flexibility, and will continue to seek additional actions to mitigate the impact of macroeconomic uncertainty. Unforeseen macroeconomic conditions could result in additional actions that could adversely affect equity performance until market conditions improve. For additional information, see Part II Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations and Note 5 to the Consolidated Financial Statements.

Sales of the Company's products are also subject to extensive federal, state, local and foreign laws and regulations; trade agreements; import and export controls; taxes; and duties and tariffs. The imposition of additional regulations, controls, taxes, duties and tariffs or changes to bilateral and regional trade agreements could also result in lower sales volume, which could negatively impact the Company’s results of operations.

During 2025, the United States changed its long-standing trade policies and announced significant new tariffs, with certain exceptions, on virtually all imported goods. These actions triggered the negotiation of new trade agreements with certain U.S. trading partners. While these negotiations resulted in the reduction of certain recently imposed tariffs, the average U.S. tariff rate remains at its highest level since the 1930s. In response to the changes in U.S. trade policies, certain U.S. trading partners imposed retaliatory tariffs on U.S. imports. Shifts in tariffs, trade agreements, import/export restrictions, trade sanctions, sector specific trade barriers, and other governmental trade actions, whether enacted by the United States or other countries, especially those instituted in the Company's significant markets or markets where its significant customers or suppliers are located, and the associated uncertainty of long-term trade policies, could impact the Company's sales volume, sales price, and production and other costs. Changes in trade policies may also cause disruptions to material sourcing and availability, global supply chains and logistics and access to end markets. Additionally, changes in U.S. trade policy and associated responses from trading partners may create shifts in global market dynamics, disrupt the long-term planning process for governments and private enterprises and result in continued global financial market volatility. The impact of these changes in trade policies and the resulting trade and market uncertainty could have a negative impact on the Company’s results of operations. There can be no assurance that, in the future, the United States, other countries or international trade bodies will not institute new tariffs or more restrictive trade policies or remedies and, as a result, the Company may face additional uncertainty and adverse impact on its business, financial condition and results of operations.

Economic conditions around the world, and in certain industries and geographic regions in which the Company does business, also impact sales price and volume and the efficacy of the Company's supply chain. For example, long-term market uncertainty, an economic downturn driven by trade policies and inflationary pressures, and higher input costs have reduced demand for the Company's products, resulting in decreased sales price and volume. Adverse economic conditions have also caused supply chain constraints. These factors have had and are continuing to have a negative impact on the Company's results of operations. Additionally, political conditions or tensions; war, invasion or conflict, including the ongoing conflicts in the Middle East and between Russia and Ukraine with the related sanctions and export restrictions; terrorism; epidemics; pandemics; or political instability in the geographic regions or industries in which the Company operates or sells its products could further reduce demand for the Company's

22

Table of Contents

products and result in decreased sales price and volume or supply chain disruptions, which could have a negative impact on the Company’s results of operations.

The Russia-Ukraine conflict has been ongoing for more than three years since Russia's February 2022 invasion of Ukraine, and although there have been recent efforts to seek a resolution, it remains unclear if these will be successful. In light of sanctions imposed by the United States, Canada, the European Union and other countries as a result of this conflict, Dow ceased in-bound investment to Russia and maintains reasonable, risk-based measures to ship into Russia only limited goods that comply with applicable legal restrictions. These actions have not had and are not expected to have a material impact on the Company's financial condition or results of operations. The situation remains fluid and the ongoing conflict may result in additional economic sanctions or other measures, which could have a negative impact on the Company’s financial condition, results of operations and cash flows. These impacts could include decreased sales; supply chain and logistics disruptions; volatility in foreign exchange rates and interest rates; inflationary pressures on and availability of raw materials and energy, most notably in Europe; and heightened cybersecurity threats. Further, the intensity and duration of conflicts in the Middle East and potential expansion of hostilities in the region are difficult to predict and could disrupt the Company's supply chain operations, which could have a negative impact on the Company's results of operations.

In addition, volatility and disruption of financial markets could limit the ability of Dow's customers and suppliers to obtain adequate financing to maintain operations, which could result in a decrease in sales volume and have a negative impact on the Company’s results of operations. The Company’s global business operations also give rise to market risk exposure related to changes in inflation, foreign currency exchange rates, including the impact of foreign currency exchange rates resulting from highly inflationary economies such as Argentina, interest rates, commodity prices and other market factors such as equity prices. To manage such risks, the Company enters into hedging and other investment transactions, where deemed appropriate, pursuant to established guidelines and policies. If the Company fails to effectively manage such risks, it could have a negative impact on its results of operations.

Pension and Other Postretirement Benefits: Increased obligations and expenses related to the Company's defined benefit pension plans and other postretirement benefit plans could negatively impact its financial condition and results of operations.

While the Company has frozen its defined benefit plans and other postretirement benefit plans in the United States, the Company continues to sponsor these plans as well as defined benefit pension plans and other postretirement benefit plans in a number of other countries (together with U.S. plans, the “plans”). The assets of the Company's funded plans are primarily invested in fixed income securities, equity securities of U.S. and foreign issuers and alternative investments, including investments in real estate, private equity and absolute return strategies. Changes in the market value of plan assets, investment returns, discount rates, mortality rates and regulations may affect the funded status of the Company's plans and could cause volatility in the net periodic benefit cost and future funding requirements of the plans. A significant increase in the Company's obligations or future funding requirements could have a negative impact on the Company's results of operations and cash flows for a particular period and on the Company's financial condition.

Supply/Demand Balance: Earnings generated by the Company's products vary based in part on the balance of supply relative to demand within the industry.

The Company's business operations are subject to the cyclical nature of the supply-demand balance in the chemical industry. The balance of supply relative to demand within the industry has been and continues to be significantly impacted by the addition of new capacity, especially for basic commodities where capacity is generally added in large increments as world-scale facilities are built. This has resulted in excess capacity which has disrupted and continues to disrupt regional industry supply and demand balances, particularly in Europe, the Middle East, Africa and India ("EMEAI") and Asia Pacific, resulting in downward pressure on prices and decreased operating rates, which has had and continues to have a negative impact on the Company’s results of operations.

LEGAL AND REGULATORY RISKS

Environmental Compliance: The costs of complying with evolving regulatory requirements could negatively impact the Company's financial results. Actual or alleged violations of environmental laws or permit requirements could result in restrictions or prohibitions on plant operations, substantial civil or criminal sanctions, as well as the assessment of strict liability and/or joint and several liability.

The Company is subject to extensive federal, state, local and foreign laws, regulations, rules and ordinances relating to pollution, protection of the environment, climate change, greenhouse gas emissions, and the generation, storage, handling, transportation, treatment, disposal and remediation of hazardous substances and waste

23

Table of Contents

materials. In addition, the Company may have costs related to environmental remediation and restoration obligations associated with past and current sites as well as related to its past or current waste disposal practices or other hazardous materials handling. Although management will estimate and accrue liabilities for these obligations, it is reasonably possible that the Company’s ultimate cost with respect to these matters could be significantly higher, which could negatively impact the Company’s financial condition and results of operations. Costs and capital expenditures relating to environmental, health or safety matters are subject to evolving regulatory requirements and depend on the timing of the promulgation and enforcement of specific standards which impose the requirements. Moreover, changes in environmental regulations could inhibit or interrupt the Company’s operations, or require modifications to its facilities. Further, additional environmental disclosure obligations require and may continue to require the Company to implement new practices and reporting processes, and have created and will continue to create additional compliance risk. Accordingly, environmental, health or safety regulatory matters could result in significant unanticipated costs or liabilities. For additional information, see Part II, Item 7. Other Matters, Environmental Matters in Management’s Discussion and Analysis of Financial Condition and Results of Operations.

Health and Safety: Increased concerns regarding the safe use of chemicals and plastics in commerce and their potential impact on the environment have resulted in more restrictive regulations and could lead to new regulations.

Concerns regarding the safe use of chemicals and plastics in commerce and their potential impact on health and the environment reflect a growing trend in societal demands for increasing levels of product safety and environmental protection. These concerns could manifest themselves in stockholder proposals, preferred purchasing, delays or failures in obtaining or retaining regulatory approvals, delayed product launches, lack of market acceptance and continued pressure for more stringent regulatory intervention and litigation. These concerns could also influence public perceptions, the viability or continued sales of certain of the Company's products, its reputation and the cost to comply with regulations. In addition, terrorist attacks and natural disasters have increased concerns about the security and safety of chemical production and distribution. These concerns could have a negative impact on the Company's results of operations.

Local, state, federal and foreign governments continue to propose new regulations related to the security of chemical plant locations and the transportation of hazardous chemicals, which could result in higher operating costs.

Litigation: The Company is party to a number of claims and lawsuits arising out of the normal course of business with respect to product liability, patent infringement, employment matters, governmental tax and regulation disputes, contract and commercial litigation, and other actions.

Certain of the claims and lawsuits facing the Company purport to be class actions and seek damages in very large amounts. All such claims are contested. With the exception of the possible effect of the asbestos-related liability of Union Carbide Corporation (“Union Carbide”) as described below, it is the opinion of the Company’s management that the possibility is remote that the aggregate of all such claims and lawsuits will have a material adverse impact on the Company’s consolidated financial statements.

Union Carbide is and has been involved in a large number of asbestos-related suits filed primarily in state courts during the past several decades. At December 31, 2025, Union Carbide's total asbestos-related liability, including future defense and processing costs, was $708 million ($791 million at December 31, 2024).

Plastic Waste: Increased concerns regarding plastic waste in the environment, resulting in the demand for substitute materials; brand owners selectively reducing their use of plastic products; a lack of plastic waste collection and recycling infrastructure and a failure to develop circular plastic materials or a circular economy for plastics; and/or the development of new or more restrictive regulations and rules related to plastic waste and related emissions could reduce demand for the Company’s plastic products and could negatively impact the Company’s financial results.

Plastics have faced increasing public scrutiny due to low recycling rates and the presence of plastic waste in the environment, including the world’s oceans and rivers, and pollution associated with the manufacture of plastics. Accordingly, regulators, manufacturers, brand owners and consumers are driving demand for materials made with recycled content, bio-based materials and materials made with low or zero carbon emission options, and local, state, federal and foreign governments are proposing and implementing regulations to address the global plastic waste challenge, including, but not limited to, extended producer responsibility fees, recycled content mandates, taxes on plastics at the national level and bans on non-essential items. Further, an intergovernmental negotiation committee is in the process of negotiating an international legally binding instrument to end plastic pollution.

Dow is one of the world’s largest plastics producers and sells plastic products that continue to enable increasing quality and standards of living and offer significant greenhouse gas reductions compared with alternative solutions. In order to both maintain the benefits of plastics, meet growing demand for circular and renewable plastics and advance efforts to end plastic pollution in the environment, the Company is partnering with other organizations to bring the waste back into the circular economy. The Company's circularity targets aim to transform plastic waste and other forms of waste to commercialize 3 million metric tons of circular and renewable solutions by 2030. Further, the Company has committed to reducing its net annual greenhouse gas emissions and intends to be carbon neutral by 2050 (Scope 1+2+3, as defined by the Greenhouse Gas Protocol Corporate Accounting and Reporting Standard, plus product benefits).

Without the expansion of proper waste collection and recycling infrastructure and the development of a circular economy for plastics at scale, along with increased pressure to reduce the use of plastics, the Company could experience reduced demand for its polyethylene products, which could negatively impact the Company’s financial condition, results of operations and cash flows.

OPERATIONAL AND STRATEGIC RISKS

Company Strategy: Implementing certain elements of the Company's strategy could negatively impact its financial results.

The Company currently has manufacturing operations, sales and marketing activities, and joint ventures in emerging geographic regions. Activities in these geographic regions are accompanied by uncertainty and risks including: navigating different government regulatory environments; relationships with new, local partners; project funding commitments and guarantees; expropriation, military actions, war, terrorism, sanctions and political instability; sabotage; uninsurable risks; suppliers not performing as expected resulting in increased risk of extended project timelines; and determining raw material supply and other details regarding product movement.

The Company also makes strategic investments in emerging companies. While the Company pursues strategic investments because it expects them to yield longer-term benefits, they could adversely affect the Company’s near-term results of operations. These investments may not yield the business benefits, synergies or financial benefits anticipated by management.

Additionally, disruptions to supply chains, distribution chains and/or public and private infrastructure and services, including those caused by industry capacity constraints, material availability, global logistics delays, and third party service and material providers; and constraints arising from, among other things, the transportation capacity of ocean shipping containers; global labor availability constraints; and/or disruptions to the Company's site operations caused by tenant and neighboring manufacturing operations, as well as the Company's ability to attract and retain a talented workforce, could materially and adversely impact the Company's business operations.

If the manufacturing operations, supply chains, sales and marketing activities, investments in emerging companies and joint venture operations are not reliable and/or the implementation of the Company's projects is not successful, it could adversely affect the Company’s financial condition, cash flows and results of operations.

Cybersecurity Threat: Disruption of the Company's information technology, data security, and other operating or third-party systems, including disruption of the ability to safely and reliably operate the Company's facilities; the risk of loss of the Company’s proprietary information including trade secrets, know-how or other sensitive business information; and the risk of loss or security of the private data of the Company, its customers and its employees could negatively impact the Company’s business strategy, results of operations, financial condition and reputation.

The Company relies on various information systems, including information systems operated by third-parties and which may also include embedded artificial intelligence ("AI"), to support safe, efficient and reliable business and operating processes and activities and to safeguard its proprietary information assets, including trade secrets, know-how and other sensitive, business critical information. These systems are critical to the Company's process to accurately report financial results for management and external reporting purposes and to ensure compliance with financial reporting, legal and tax requirements in the United States and around the world. These systems may also be used to collect and process sensitive customer and personal employee data the Company may be legally required to store, process and protect in accordance with complex country- and territory-specific laws that continue to evolve, violations of which could result in significant criminal or civil sanctions, investigations, or enforcement actions.

Table of Contents

Increased global cybersecurity vulnerabilities, threats and targeted cyberattacks, which are becoming more sophisticated as attackers increase their utilization of developing techniques and tools, including AI, continue to pose risks to the Company’s products, systems and networks, and the confidentiality, availability and integrity of the Company’s data, and may surpass the Company's current safeguards. These vulnerabilities also expose the Company’s customers, suppliers and third-party service providers to loss. In addition, the Company is exposed to similar risks resulting from cyberattacks that are experienced by its suppliers and other vendors. As a result, cyberattacks, internal and external security breaches, and attacks and security breaches of third-party systems could disrupt the Company's operations, compromise Dow’s proprietary and confidential, business critical information, jeopardize the Company's ability to safeguard and maintain accurate data, including personal data, and harm the Company's reputation which could result in litigation, enforcement actions, including fines, penalties and disruption of the Company's right to operate in certain jurisdictions, and significant remediation costs. Additionally, the Company’s use of AI software may create additional risks related to the unintentional disclosure of proprietary, confidential, personal or otherwise sensitive information.

While the Company has been the target of cyberattacks, including phishing, social engineering, industrial espionage and other malicious attacks, and has determined that certain of these attacks have resulted in and could continue to result in unauthorized third parties gaining access to the Company's information systems and certain confidential business information, the Company has a comprehensive cybersecurity program that is continuously reviewed, maintained and upgraded and, to date, these attacks have not materially impacted the Company. However, cyberattacks by nation-state organizations, crime organizations and other hackers continue to occur and are increasingly sophisticated, and these attacks may occur and remain undetected for an extended period of time. These attacks could have a material negative impact on the Company’s business strategy, results of operations, financial position and reputation. More information on the Company’s processes for assessing, identifying and managing material risks from cybersecurity threats, including management’s role and the Board's oversight of such processes, can be found in Item 1C. Cybersecurity.

Goodwill: An impairment of goodwill could negatively impact the Company’s financial results.

At least annually, the Company assesses goodwill for impairment. If testing indicates that goodwill is impaired, the carrying value is written down based on fair value with a charge against earnings. Where the Company utilizes a discounted cash flow methodology in determining fair value, continued weak demand for a specific product line or business could result in an impairment. Accordingly, any determination requiring the write-off of a significant portion of goodwill could negatively impact the Company's results of operations. See Note 12 to the Consolidated Financial Statements for additional information regarding the Company's goodwill impairment testing and goodwill impairments, including goodwill impairments recognized during the fourth quarter of 2025.

Operational Event: A significant operational event could negatively impact the Company's results of operations.

As a diversified chemical manufacturing company, the Company's operations at each site, including maintenance of its facilities; the transportation of supplies and products; cyberattacks; the expanding utilization of AI in Company operations, including but not limited to its manufacturing process controls, supply chain optimization, and human resources analysis, and by its suppliers and customers, and the complex and evolving regulatory environment surrounding AI; and pandemics and other public health-related events or severe weather conditions and other natural phenomena (such as freezing, drought, hurricanes, earthquakes, tsunamis, floods, etc.) could result in an unplanned or unintended event that could be significant in scale and could negatively impact operations, neighbors or the public at large, which could have a negative impact on the Company's results of operations.

Major hurricanes and other weather-related events have caused significant disruption in the Company's operations on the U.S. Gulf Coast, logistics across the region, and the supply of certain raw materials, which had an adverse impact on volume and cost for some of its products. Due to the Company's substantial presence on the U.S. Gulf Coast, similar severe weather conditions or other natural phenomena in the future could negatively impact the Company's results of operations. Other non-weather-related unplanned events have also caused disruptions in the Company’s operations at various sites. While the Company has processes in place to minimize the risks and impacts of such events, such unplanned future events could negatively impact the Company’s results of operations.

Raw Materials and Energy: Availability of purchased feedstock and energy, and the volatility of these costs, impact Dow’s operating costs and add variability to earnings.

Purchased feedstock and energy costs account for a substantial portion of the Company’s total production costs and operating expenses. The Company purchases hydrocarbon-based raw materials including ethane, propane, butane, naphtha and condensate as feedstocks and purchases certain monomers, primarily ethylene and

26

Table of Contents

propylene, to supplement internal production, as well as other raw materials. The Company also purchases natural gas, primarily to generate electricity, electric power to supplement internal generation, and steam.

Feedstock and energy costs generally follow price trends in crude oil and natural gas, which are sometimes volatile. Power prices often follow general energy trends, and are additionally subject to short-term surfeits and shortages related to, for example, intermittent wind and solar generation, and power generation and transmission outages. While the Company uses its feedstock flexibility and financial and physical hedging programs to help mitigate feedstock cost increases, the Company is not always able to immediately raise selling prices. Ultimately, the ability to pass on underlying cost increases is dependent on market conditions. Conversely, when feedstock and energy costs decline, selling prices generally decline as well. As a result, volatility in these costs could impact the Company’s results of operations.

While the Company expects abundant and cost-advantaged supplies of natural gas liquids ("NGLs") in the United States to persist for the foreseeable future, if NGLs become significantly less advantaged than crude oil-based feedstocks, it could have a negative impact on the Company’s results of operations and future investments. Also, if the Company’s key suppliers of feedstock and energy, which may include limited or single source suppliers, are unable to provide the raw materials or energy required for production, it could have a negative impact on the Company’s results of operations.

Public Health Crisis: A public health crisis or global outbreak of disease could have a negative effect on the Company's manufacturing operations, supply chain and workforce, creating business disruptions that couldhave a substantial negative impact on the Company’s results of operations, financial condition and cash flows.

A public health crisis, including a pandemic similar in nature to COVID-19, could impact all geographic regions where Dow products are produced and sold. The global, regional and local spread of a public health crisis could result in, and in the past has resulted in, significant global mitigation measures, including government-directed quarantines, social distancing and shelter-in-place mandates, travel restrictions and/or bans, mask and vaccination mandates, restrictions on large gatherings and restricted access to certain corporate facilities and manufacturing sites. Business disruptions and market volatility resulting from a public health crisis could have a substantial negative impact on the Company’s results of operations, financial condition and cash flows. The adverse impact of a pandemic could include, and in the past has included, without limitation, fluctuations in the Company’s stock price due to market volatility; a decrease in demand for certain Company products; price declines; reduced profitability; supply chain disruptions impeding the Company’s ability to ship and/or receive product; temporary idling or permanent closure of select manufacturing facilities and/or manufacturing assets; asset impairment charges; interruptions or limitations to manufacturing operations imposed by local, state or federal governments; reduced market liquidity and increased borrowing costs; workforce absenteeism and distraction; labor shortages; customer credit concerns; increased cybersecurity risk and data accessibility disruptions due to remote working arrangements; workforce reductions and fluctuations in foreign currency markets. Additional risks may include, but are not limited to: shortages of key raw materials; potential impairment in the carrying value of goodwill; additional asset impairment charges; increased obligations related to the Company’s pension and other postretirement benefit plans; and tax valuation allowance; and may also have the effect of heightening many of the other risks described in this "Risk Factors" section.

ITEM 1C. CYBERSECURITY

Risk Management and Strategy

The Company has processes in place to identify, assess and monitor material risks from cybersecurity threats, which are part of the Company’s overall enterprise risk management process and have been embedded in the Company’s operating procedures, internal controls and information systems.

Dow's comprehensive cybersecurity and information security framework includes risk assessment and mitigation through a threat intelligence-driven approach, application controls, and enhanced security with ransomware defense. The framework leverages International Organization for Standardizations 27001/27002 standards for general information technology controls, International Society of Automation/International Electrotechnical Commission standards for industrial automation, the National Institute of Standards and Technology Cyber Security Framework ("NIST CSF") for measuring overall readiness to respond to cybersecurity threats, and Sarbanes-Oxley for assessment of internal controls. In addition, the Company maintains business continuity and disaster recovery plans as well as a cybersecurity insurance policy.

Dow has comprehensive processes to manage cybersecurity risks when engaging with third-party service providers, including reviewing questionnaires and independent quantitative scores of the vendor’s cybersecurity hygiene, maintaining robust controls to address and mitigate significant risks that may arise, and performing ongoing assessments and reviews throughout the duration of the engagement.

Dow has established cybersecurity and information security awareness training programs. Formal training on topics relating to the Company’s cybersecurity, data privacy and information security policies and procedures is mandatory at least annually for all employees, contractors and third parties with access to the Company’s network. Training is administered and tracked through online learning modules. Training topics include how to escalate suspicious activities including phishing, viruses, spams, deep fakes, insider threats, suspect human behaviors or safety issues. Based on role and location, some employees receive additional in-depth training to provide more comprehensive knowledge on potential risks related to their individual job responsibilities. Training is supplemented through regular Company communications with frequent updates to educate on the latest adversary trends and social engineering techniques.

Additionally, Dow engages in cybersecurity crisis response simulations to assess Dow’s ability to adapt to information and operational technology threats. Improper or illegitimate use of the Company’s information system resources or violation of the Company’s information security policies and procedures is subject to disciplinary action. Dow’s security posture is supported by a comprehensive defense-in-depth strategy that relies on layers of technology including, but not limited to, Multi-Factor Authentication and Zero Trust principles to ensure that access to information and communication is vetted and secure.

Dow also utilizes internal and external audits and assessments, vulnerability testing, governance processes over outsourced service providers, active risk management and benchmarking against peers in the industry to validate Dow’s security posture. The Company also engages external firms to measure Dow’s NIST CSF maturity level.

As of the date of this report, no risks from cybersecurity threats, including those resulting from any previous cybersecurity incidents, have materially affected, or are reasonably likely to materially affect, the Company, including its business strategy, results of operations or financial condition. Although the Company has mature processes in place to identify and mitigate potential risks from cybersecurity threats, such risks cannot be completely eliminated. More information on the risks of cybersecurity threats and potential impact to the Company can be found in Item 1A. Risk Factors.

Governance

Role of Management

Dow’s information systems organization is led by Dow’s chief information & digital officer, who reports to Dow's chief operating officer, and is responsible for administration of the cybersecurity and information security framework and risk management, with oversight by the Audit Committee of the Board.

The Company’s chief information & digital officer has formal education in information technology and more than 30 years of experience in information systems and technology, including as the vice president of Global Information Technology at Cargill, Incorporated, prior to joining Dow. The chief information & digital officer receives regular updates on cybersecurity matters, results of mitigation efforts and cybersecurity incident response and remediation.

28

Table of Contents

The Company’s management responsible for developing and executing Dow’s cybersecurity policies is comprised of individuals with either formal education and degrees in information technology or cybersecurity, or with experience working in information technology and cybersecurity, including relevant experience in security related industries. Additionally, leaders in the Company’s information technology function receive periodic training and education on cybersecurity related topics. Certain leaders also obtain industry certifications, such as Certified Information Systems Security Professional or Certified Information Security Manager.

The Company’s Cyber Security Operations Center (“CSOC”) serves as the central point for all cybersecurity incidents and reporting, including incidents that directly target employees or Dow internal information systems and incidents originating from third parties. The CSOC provides end-to-end operations for purposes of monitoring, detecting, alerting and responding to cybersecurity incidents. The CSOC evaluates each incident in terms of its impact on the Company’s operations, ability to conduct business with customers and suppliers, brand reputation and health, safety or the environment, and the speed and degree to which the incident has been contained. The CSOC is also responsible for activating the containment and resolution efforts and third-party service providers are engaged where appropriate to support the Company through the resolution of the incident.

The CSOC reports all cybersecurity incidents to the Company’s Materiality Assessment Team, which includes senior representatives from information technology, finance, legal and other relevant business functions. If the Materiality Assessment Team initially assesses that a cybersecurity incident may be material, the CSOC immediately notifies the Cybersecurity Executive Steering Team for final determination of materiality. The Cybersecurity Executive Steering Team consists of the chief operating officer; chief financial officer; chief information & digital officer; chief information security officer; senior vice president, operations, manufacturing & engineering; chief technology & sustainability officer; vice president of government affairs; and general counsel. The CSOC escalates incidents with significant impact and pervasiveness to the Company’s Corporate Crisis Management Team for further action. After initial identification, the CSOC monitors all cybersecurity incidents for changes in degree of impact or pervasiveness to ensure timely escalation and response. Decisions of the Cybersecurity Executive Steering Team are communicated through established governance channels, including reporting to the Audit Committee of the Board. This process is integrated into the Company’s overall incident response and risk management framework, ensuring alignment between operational response and strategic oversight.

Role of the Board

Dow's Board recognizes the importance of cybersecurity in safeguarding the Company’s sensitive data. The Board is responsible for overseeing overall risk management for the Company, including review and approval of the enterprise risk management approach and processes implemented by management to identify, assess, manage and mitigate risk, at least annually. While the full Board is accountable for cybersecurity and AI risk management and is presented with an annual cybersecurity update, the Board has delegated responsibility for oversight of the Company’s cybersecurity and information security framework and risk management to the Audit Committee of the Board. The Audit Committee receives information and updates at least quarterly and actively engages with senior leaders, including the chief information & digital officer and chief information security officer, with respect to the effectiveness of the Company’s cybersecurity and information security framework, data privacy, and risk management. In addition, the Audit Committee receives reports summarizing threat detection and mitigation plans, audits of internal controls, training and certification, and other cybersecurity priorities and initiatives, as well as timely updates from senior leaders on material incidents relating to information systems security, including cybersecurity incidents. The Audit Committee also reviews external firms’ assessments of the Company’s security posture and NIST CSF maturity level. Information made available to the Audit Committee is also made available to the full Board. The Audit Committee includes members with significant experience and/or expertise in technology or cybersecurity, including information systems.

STATEMENT ON MACROECONOMIC CONDITIONS AND CURRENCY EXCHANGE RATES

Overview of Macroeconomic Conditions and the Company’s Response

The Company has continued to face challenging market conditions in 2025, including the significant impact of slower global GDP growth. Industry overcapacity and newer entrants exporting at anti-competitive economics have negatively impacted the Company’s results of operations and cash flows and are expected to continue to do so. In addition, the current uncertain geopolitical environment, including the impact of trade policies, has resulted in increased volatility in global markets, also negatively impacting the Company’s results of operations and cash flows. The macroeconomic conditions experienced in 2025 are expected to persist in the near term for the Company and the industry alike.

Despite these challenges, the Company has maintained a strong financial position and solid liquidity and has taken actions to mitigate impacts on its supply chain and results of operations. At the time of this filing, the ultimate impact of tariff policies and other evolving global trade measures, coupled with existing macroeconomic challenges, is uncertain. The Company is actively monitoring global trade developments to identify actions necessary to maintain competitiveness while it adapts to these new economic challenges and continuing to work with regulatory bodies to address anti-competitive behavior. More information on these risks and potential impact to the Company can be found in Part I, Item 1A. Risk Factors.

In the first quarter of 2025, Dow announced targeted cost actions to reduce structural costs by $1 billion over the next two years, while its businesses work to balance supply with profitable demand. The cost actions target areas such as third-party spending and include a workforce reduction of approximately 1,500 roles. The Company also announced reductions to its capital expenditures for 2025.

The Company announced further actions to address ongoing macroeconomic volatility and persistently slower global GDP growth in the second quarter of 2025, including the decision to delay construction of its Path2Zero project in Fort Saskatchewan, Alberta, Canada. The Company’s expected 2025 enterprise-wide capital expenditures were adjusted to $2.5 billion from the Company's original plan of $3.5 billion after the actions taken in the first and second quarters of 2025.

In January 2026, the Company provided an updated timeline for its Fort Saskatchewan Path2Zero project, delaying completion of the project by two years, and expects the first and second phases of the project to start up by the end of 2029 and 2030, respectively. Dow remains committed to its Path2Zero project and the growth upside it will enable in targeted applications like pressure pipe, wire and cable, and food packaging. The project is expected to be the world’s first net-zero Scope 1 and 2 carbon dioxide equivalent emissions integrated ethylene and derivatives complex.

On July 7, 2025, the Company announced additional restructuring actions, approved by its Board of Directors ("Board") on June 30, 2025, to rationalize its global asset footprint, including actions related to the three assets identified as part of the Company’s expanded strategic review of its European assets and certain corporate and other assets, and to enhance the Company’s competitiveness over the economic cycle. The program includes asset write-down and write-off charges, severance and related benefit costs, contract termination fees and other exit and disposal costs. These actions will be completed by the Company primarily over the next four years, including the asset shut downs and completion of the related decommissioning and demolition activities. Significant actions approved to date include the following:

Beginning with the third quarter of 2025, the Company’s Board reduced the dividend by 50 percent to $0.35 per share, in response to the prolonged industry downturn. The adjustment to the size of the dividend reflects the Company’s balanced capital allocation approach and enhances financial flexibility amidst a persistently challenging macroeconomic environment.

On January 29, 2026, the Company announced Transform to Outperform, a comprehensive set of actions designed to improve near-term Operating EBITDA by simplifying the Company’s operating model, reducing its cost structure and delivering faster growth. Transform to Outperform is expected to deliver at least $2 billion near-term Operating EBITDA improvement from productivity improvements and growth and will be accretive to the $1 billion structural cost reductions announced in the first quarter of 2025. The Company expects to incur one-time costs and charges related to Transform to Outperform of $1.1 billion to $1.5 billion, including severance and related benefit costs of $600 million to $800 million associated with approximately 4,500 roles. Charges for severance and related benefit costs and the related implementation costs will be incurred primarily over the next two years.

Currency Exchange Rates

The Company's global business operations give rise to market risk exposure related to changes in foreign currency exchange rates and international capital flows that may be affected by extensive regulations and controls, especially in developing or highly inflationary countries such as Argentina. The Company continues to monitor these situations and take appropriate actions as necessary to manage the financial impact pursuant to established guidelines and policies. If the Company is unable to manage certain exposures in a cost-effective manner it could have a significant negative impact on its future results of operations and cash flows. A detailed discussion of these and other principal risks and uncertainties, which may negatively impact the future results of the Company, are included in Part I, Item 1A. Risk Factors.

The impact of currency on net sales was flat compared with 2024.

Restructuring, goodwill impairment and asset related charges - net were $1,856 million in 2025 compared with $103 million in 2024.

Net sales decreased across all operating segments and geographic regions. Local price decreased across all operating segments and geographic regions driven by industry supply and demand dynamics and lower global energy and feedstock costs. Local price decreased in Packaging & Specialty Plastics (down 8 percent), Industrial Intermediates & Infrastructure (down 6 percent) and Performance Materials & Coatings (down 3 percent).

Cost of Sales

Cost of sales ("COS") was $37.4 billion in 2025, compared with $38.4 billion in 2024. COS decreased in 2025 primarily due to lower raw material, feedstock and energy costs, the impact of the Company's cost reduction initiatives, and lower planned maintenance turnaround spending, partially offset by the impact of lower operating rates. COS as a percentage of net sales was 93.7 percent in 2025, compared with 89.3 percent in 2024. The increase in COS as a percentage of net sales was driven by the impact of lower local price on flat net sales volume.

Research and Development Expenses

Research and development ("R&D") expenses were $752 million in 2025, compared with $810 million in 2024. R&D expenses decreased in 2025 primarily due to the Company's cost reduction initiatives and lower performance-based compensation costs.

Amortization of Intangibles

Amortization of intangibles was $231 million in 2025, compared with $310 million in 2024.
