TABLE OF CONTENTS

OUR BUSINESS

Weyerhaeuser Company is one of the world's largest private owners of timberlands. We own or control 10.5 million acres of timberlands in the U.S. and manage an additional 14.1 million acres of timberlands under long-term licenses in Canada. We manage these timberlands on a sustainable basis in compliance with internationally recognized forestry standards. Our objective is to maximize the long-term value of timberlands we own. We analyze each timberland acre comprehensively to understand its highest-value use. We realize this value in many ways, most notably through growing and harvesting the trees, but also by selling properties when we can create incremental value. In addition, we focus on opportunities to realize value through lease and royalty agreements for the surface and subsurface rights that exist in our ownership.

We are also one of the largest manufacturers of wood products in North America. We manufacture and distribute high-quality wood products, including structural lumber, oriented strand board, engineered wood products and other specialty products. These products are primarily supplied to the residential, multi-family, repair and remodel, industrial and light commercial markets. We operate 35 manufacturing facilities in the United States and Canada.

Sustainability and citizenship are part of our core values. Our sustainably managed forests and our wood products play a critical role in mitigating climate change, and our carbon record shows that our net impact is significantly carbon negative. In addition to practicing sustainable forestry, we focus on energy and resource efficiency, reducing greenhouse gas emissions, conserving natural resources and offering sustainable products that meet our customers' needs. We operate with industry-leading safety results, actively support the communities in which we operate and communicate transparently with our investors and other stakeholders. We are recognized for our leading performance in the areas of ethics, citizenship and gender equality.

WHO WE ARE

We were incorporated as Weyerhaeuser Timber Company in the state of Washington in January 1900, when Frederick Weyerhaeuser and 15 partners bought 900 thousand acres of timberland. Today, we are working to be the world's premier timber, land and forest products company for our shareholders, customers and employees.

REAL ESTATE INVESTMENT TRUST (REIT)

Weyerhaeuser Company is a REIT and REIT income can be distributed to shareholders without first paying corporate level tax, substantially eliminating the double taxation on income. We also own timberland assets through a subsidiary, Weyerhaeuser Timber Holdings, Inc., which qualifies as a REIT under the Internal Revenue Code of 1986, as amended (IRC), for tax years beginning 2022. We expect to derive most of our REIT income from our timberlands, including gains from the sales of our standing timber and rent from recreational leases. We are required to pay federal corporate income taxes on earnings of our Taxable REIT Subsidiaries (TRSs), which include our Wood Products segment and a portion of our Timberlands and Real Estate, Energy and Natural Resources segments.

OUR BUSINESS SEGMENTS

In our Management’s Discussion and Analysis of Financial Condition and Results of Operations (MD&A) section you will find discussion of our overall performance results for our business segments, which are as follows:

Detailed financial information about our business segments and our geographic locations is provided in Note 2: Business Segments and Note 20: Geographic Areas.

EFFECT OF MARKET CONDITIONS

The health of the U.S. housing market strongly affects the performance of all our business segments. Our Wood Products segment primarily sells into the new residential building and repair and remodel markets. Demand for sawlogs within our Timberlands segment is directly affected by domestic production of wood-based building products as well as export markets. Seasonal weather patterns impact the level of construction activity in the U.S., generally characterized by a reduction in activity during the winter months, which in turn affects the demand for our logs and wood products. Our Real Estate & ENR segment is affected by a variety of factors, including the general state of the economy, local real estate market conditions, the level of construction activity in the U.S. and the evolution of emerging renewable energy and carbon-related markets.

COMPETITION IN OUR MARKETS

We operate in highly competitive domestic and foreign markets, with numerous companies selling similar products. Many of our products also face competition from substitutes for wood products. We compete in our markets primarily through product quality, service levels and price. We are relentlessly focused on operational excellence, producing quality products customers want and are willing to pay for, at the lowest possible cost.

Our business segments’ competitive strategies are as follows:

ENVIRONMENTAL, SOCIAL AND GOVERNANCE (ESG) PRACTICES

Sustainability is one of the core values of our company and has been for over 100 years. We have spent decades building a solid foundation characterized by excellence in environmental stewardship, social responsibility and corporate governance. Maintaining a strong ESG foundation is a key component of our ability to drive long-term shareholder value, and these principles guide us in how we conduct our business every day.

ENVIRONMENTAL STEWARDSHIP

As a pioneer in sustainable forestry, we have environmental stewardship deeply rooted in our business and very much at the core of our company. To operate successfully, we need our forests to provide a sustainable supply of wood fiber now and long into the future. To ensure our forests remain healthy and valuable for decades to come, we protect and enhance the many additional benefits they provide, such as clean water, clean air and critical areas for biodiversity. We also enhance the environmental footprint in our wood products manufacturing business, including reducing air emissions, minimizing waste and maximizing wood recovery. These actions are prudent for our business, good for the environment and essential to how we run our operations sustainably.

PRACTICING SUSTAINABLE FORESTRY

As one of the world’s oldest and largest private timberland owners, we’ve been growing, harvesting and regrowing forests for more than a century. We have been managing our forests sustainably for a very long time. We advocated for legislation in 1925 to encourage reforestation after harvest, which was an uncommon practice at the time. In 1937, we began research into sustainable yield forestry, which ensures harvesting does not diminish a forest’s ability to provide the same volume in the future. In 1938, we were one of the first companies to plant tree seedlings, and in 1941 we established the first certified tree farm in the U.S. We harvest, on average, only two percent of our forests each year, and 100 percent of our timberlands are reforested after harvesting. We plant more than 110 million tree seedlings per year, which equates to about 210 trees planted per minute throughout the year.

CARBON RECORD

Our carbon record shows that our net impact is significantly carbon negative, meaning we remove substantially more carbon from the atmosphere than we emit each year.

In 2023, our scope 1 carbon emissions were 0.5 million metric tons of carbon dioxide equivalent (mtCO2e), primarily attributable to fuel usage within our wood products mills and fertilizer application in our timberlands. Also in 2023, our location- and market-based scope 2 emissions were 0.5 million and 0.4 million mtCO2e, respectively, which are emissions from the energy we purchase. Our scope 1 and scope 2 emissions are calculated in accordance with the Greenhouse Gas Protocol's Corporate Accounting and Reporting Standard. We obtained limited assurance of our 2023 scope 1 and scope 2 emissions from a third-party attestation provider.

In 2022, our scope 3 emissions totaled 9.2 million mtCO2e, primarily generated by customers who purchase our wood fiber and the end-of-life emissions of the products we sell. Our scope 3 emissions are calculated in accordance with the Greenhouse Gas Protocol's Corporate Value Chain (Scope 3) Accounting and Reporting Standard.

Our sustainably managed forests play a critical role in helping to mitigate climate change. As our millions of acres of forests grow, they absorb carbon dioxide from the atmosphere and store it in their trunks, limbs and roots, as well as in the soil. In 2022, our direct carbon removals totaled 2 million mtCO2e (the increase in above-ground carbon in our U.S. timberlands attributable to forest growth and management practices after we account for harvest and mortality). Also in 2022, the indirect carbon removals across our value chain were 30 million mtCO2e (primarily carbon stored in our own long-lived wood products and products that our customers make from our logs).

In 2022, our forests contained between 2.3 billion and 3.6 billion mtCO2e. Approximately 1.0 billion mtCO2e was stored in our trees and roots, and an additional 1.3 billion to 2.6 billion mtCO2e was stored in soil and other biomass. After our trees are harvested, much of their carbon remains stored in the long-lived wood products made from them for the life of those products. After harvest, we plant millions of new trees, which then begin absorbing more CO2 from the atmosphere, and the next round of wood products store more carbon yet again. Our managed forests also provide other climate benefits. They mature more quickly and are able to bank more carbon through faster, continuous rotations, all while maintaining the vast pool of carbon in the forest soil. In addition, using wood for construction requires less energy and results in fewer greenhouse gas emissions compared with other building materials, such as steel and concrete.

We have a science-based greenhouse gas emissions reduction target that has been approved by the Science Based Targets initiative at the most ambitious level, in alignment with the Paris Agreement goal of limiting global warming to 1.5 degree Celsius. Our target includes a commitment to reduce our scope 1 and 2 emissions by 42 percent overall, and our scope 3 emissions by 25 percent per ton of production, both by 2030, measured against a 2020 baseline. We are also members of The Climate Pledge, a commitment to achieve net-zero carbon emissions across our value chain by 2040. We expect to achieve these targets primarily through energy efficiency projects, increased renewable energy usage and supplier engagement. As companies across our value chain actively work to reduce their emissions, with many already taking action or making commitments, we expect our scope 3 emissions to decrease over time.

MAKING BETTER ENERGY CHOICES

We are members of the U.S. Department of Energy's (DOE) Better Plants Program, which includes a goal to improve purchased energy efficiency at our manufacturing facilities by 10 percent between 2020 and 2030. This partnership requires us to adopt a companywide goal to improve energy efficiency, annually report our progress to the DOE and develop an energy management plan. We have a comprehensive wood products energy strategy that we have begun implementing by developing short-term action plans, evaluation tools and energy champions at all sites. We also fully integrate greenhouse gas and energy metrics into capital planning processes and conduct energy audits at manufacturing sites. On average, we meet more than 70 percent of the energy needs in our manufacturing facilities from renewable biomass by using what would otherwise be wood waste from mill manufacturing residuals to create our own energy. This approach allows us to reduce our reliance on nonrenewable fossil fuels and purchased electricity. We also support other renewable energy solutions, such as wind and solar power, through our timberlands. In addition, we also supply other mills, companies and utilities with woody biomass that is used to produce renewable, carbon-neutral energy.

PROTECTING BIODIVERSITY

The forests we manage host hundreds of native vertebrate species, including large mammals such as deer, elk, cougar, black bear and bobcat, as well as a tremendous diversity of birds, reptiles, amphibians, insects, native fish and other aquatic species. Many of these species prefer different forest age classes and forest structures, or other habitat features on the landscape, such as riparian areas. Since our timberlands contain a matrix of forest stand ages, along with other special areas we protect around streams and wetlands, these forests support a high level of native biodiversity. To preserve and protect this balance, we regularly conduct biodiversity assessments across our forests as part of our ongoing stewardship and forest management operations. These assessments include analyzing species occurrence data and assessing the presence of threatened, endangered, critically imperiled, imperiled and other regionally significant species. Conducting biodiversity assessments across our land base gives us necessary insights to help design and implement best practices for habitat conservation and species protection throughout the course of our forest management activities. These practices include leaving buffers along riparian areas, surveying sites for species occurrences prior to harvesting and thinning activities, managing for specific habitat using prescribed burns or thinning harvests and refraining from harvesting during certain sensitive times.

IMPROVING CONSERVATION OUTCOMES

Ensuring our forests provide habitat features that support at-risk, sensitive or threatened and endangered species is a core component of our environmental stewardship. We pursue a number of programs to create and preserve critical habitat, including partnering on conservation easements and agreements, formal Habitat Conservation Plans (HCPs) with the U.S. federal government and mitigation banking. Conservation easements and other local agreements can assure sustainable forest practices and the long-term stewardship and protection of wildlife habitat, biodiversity and recreational access. These partnerships can be made with a variety of groups and organizations, and they allow natural resource management to continue, which helps protect the economic benefits of a working forest. HCPs are administered under the federal Endangered Species Act and help provide more specific guidance on the protection and enhancement of habitats for threatened and endangered species. We currently participate in HCPs and other conservation agreements in Alabama, Arkansas, Florida, Georgia, Louisiana, Maine, Mississippi, New Hampshire, North Carolina, Oklahoma, Oregon, South Carolina, Vermont and Washington. Authorized through the U.S. Clean Water Act, mitigation banking allows us to set aside certain areas of our timberlands to preserve, enhance or restore a wetland, stream or habitat area to make up for development by another entity in a similar nearby ecosystem. Mitigation banks are regulated and approved by the U.S. Army Corps of Engineers and a consortium of federal, state and local agencies. We currently operate 16 mitigation banks and projects, primarily in the U.S. South. Several other projects are in various stages of evaluation and development. Overall, we currently have more than 3 million acres invested in these various conservation programs in our Northern, Southern and Western Timberlands, and we are always looking for new opportunities and partnerships to expand our impact.

CONTRIBUTING TO CLEAN WATER

Our forests are critical for providing clean water to communities in our watersheds. The trees, plants and soil absorb rain and snowmelt, allowing our forests to capture and slowly release clean water into the many streams, rivers and groundwater systems on our lands. Our sustainable forestry practices help us maintain our forests' ability to capture and filter water, ensuring our harvesting methods safeguard water quality for people, fish and countless other organisms. Because our forests rely on rainwater to grow, our company’s measurable impact on water use is limited to our Wood Products manufacturing sites and offices, where water is either recycled or treated on-site, evaporated while products are drying or delivered to a local, publicly-owned treatment facility.

MINIMIZING WASTE

The primary products we produce are solid lumber, wood panels and engineered wood products. Wood shavings, sawdust, chips and bark are sold or delivered to downstream customers who make other essential products for society. Toilet paper, diapers, paper, cartons, boxes, bags, landscaping mulch and wood pellets are just a few of the countless products made from our wood fiber and forest and mill by-products. We are always looking for ways to reduce the amount of waste we generate, including finding responsible methods for reuse and recycling. On average, we reuse, recycle or repurpose 99 percent of what could have been waste in our operations. That is equal to approximately 11 billion pounds of material each year that otherwise would have found its way to a landfill.

VERIFYING WITH CERTIFICATION

To prove our forest management and wood fiber procurement practices are sustainable, we participate in independent certification programs for forest management, fiber sourcing and chain of custody. Our entire timberland portfolio is certified to the Sustainable Forestry Initiative® (SFI®) Forest Management Standard. That compares with only 11 percent of the world's forests that are certified today (the vast majority of these certified forests are in the Northern Hemisphere). Internationally recognized forest certification standards, such as SFI, Programme for the Endorsement of Forest Certification (PEFC), the American Tree Farm System®, and the Forest Stewardship Council®, provide customers and stakeholders with an objective, third-party determination of whether companies are implementing sustainable forestry practices and making products that come from legal and well-managed sources. We are vocal supporters of the importance of these standards and the use of independent, third-party audits to verify compliance and promote sustainable forestry around the world. At Weyerhaeuser, we choose to certify our timberlands and operations to SFI’s standards because they are strong, science-based standards that have effectively pushed forestry in a more sustainable direction. These standards are designed specifically for operations in North America, and we value SFI’s approach, especially around logger training and the requirement to invest in and apply research back into our operations. In addition to our forests, we certify all of our manufacturing facilities to the SFI Fiber Sourcing or Certified Sourcing standards, and select sites are certified to the SFI and PEFC Chain of Custody standards.

SOCIAL RESPONSIBILITY

Throughout our long history, social responsibility has been an integral part of how we do business. Our company needs diverse, talented workers to grow, innovate and thrive with us for decades to come. Because we depend on our people, we have a responsibility to create a safe, inclusive work environment where employees are proud to spend their careers. We also need strong communities around us, filled with people who trust and support our work.

OUR PEOPLE BY THE NUMBERS

In 2023, we employed 9,318 employees, including 7,944 in the United States, 1,364 in Canada and 10 in Japan. Of these employees, 2,367 are members of unions covered by multi-year collective-bargaining agreements.

Our employees by business segment were as follows:

SAFETY

Safety is a core value at Weyerhaeuser, which means safety comes first in everything we do. We are deeply committed to eliminating serious and fatal injuries, and to ultimately achieving an injury-free workplace. Our industry-leading safety results are driven by:

We regularly review safety incidents, risk-identification reports and “near-miss” incidents and apply key learnings across our organization. Our efforts have resulted in a significant and sustained reduction in the number and severity of recordable injuries over time. This includes a drop in our Recordable Incident Rate, which is the number of Occupational Safety and Health Administration-defined recordable injuries and illnesses that occur per 100 workers working in one year, from 10 in 1990 to 1.78 in 2023.

PEOPLE DEVELOPMENT

Developing people is a core component of our sustainable business model, and we focus a great deal of energy and resources on training, coaching and career planning. We also connect key human capital management priorities, such as succession planning, leadership development and critical role placement, with our executive compensation programs by including these and related priorities in our senior executives’ annual cash bonus plan goals. To support our people development objectives we:

We also believe in the 70-20-10 approach to professional growth. This model acknowledges that at least 70 percent of development occurs on the job through direct experience and skill building. Another 20 percent comes from focused relationship building and exposure to projects, processes and perspectives outside one’s normal expertise. The final 10 percent is focused on targeted training courses and development programs that help our employees achieve their own specific career goals. We offer three classroom-based leadership development programs that focus on helping current and future leaders build their skills. In 2023, more than 300 of our leaders participated in these programs. In addition, we expanded our online training offerings, which are accessible to all employees to take in support of their career development, and we offered a variety of virtually facilitated trainings on a range of topics. In 2023, our employees logged over 50,000 hours of training in our online learning management system, which tracks both virtual and classroom courses delivered.

DIVERSITY, EQUITY AND INCLUSION (DE&I)

Inclusion is a core value at Weyerhaeuser because we know our success depends on leveraging diverse experiences and points of view to foster innovation, facilitate better decision-making and ultimately create a stronger company. Our senior management team and board of directors regularly review our DE&I strategy and goals, which are focused on creating an inclusive environment, ensuring our policies and practices are equitable, and improving representation at all levels of the company. To achieve this, we are focused on three key areas: leadership, people and culture. We have an Inclusion Council of diverse employees from across our company and a dedicated director of DE&I who works with our leaders to set annual goals, review our progress and adjust our approach to meet evolving best practices. The Inclusion Council and our director of DE&I provide insights and ideas to our senior management team, and they are actively engaged in helping us build an inclusive culture. Our practices for achieving and maintaining a diverse, equitable and inclusive workplace include:

In response to feedback surveys conducted for 2023, 84 percent of all employees agreed their work environment is inclusive. We publish our Employment Information Report (EEO-1) summary data in the sustainability section of our website.

We will continue to closely monitor evolving best practices and will make adjustments to our approach as necessary and appropriate.

COMPANY CULTURE

We consider our strong company culture to be a competitive advantage. We are intentional in our efforts to preserve the aspects of our workplace environment that make our company a great place to work, as well as continuously improve and evolve our culture. At the heart of our culture is an unwavering commitment to our core values — safety, integrity, citizenship, sustainability and inclusion. These values are cited often by our employees and are visible throughout our organization. We also embrace five key behaviors that shape our culture and guide how we work together — urgency, accountability, courage, simplicity and innovation. To assess the health of our culture, we conduct regular companywide surveys to collect candid feedback from employees and assess overall engagement. In 2023, we conducted an engagement survey of all employees and our response rate was 77 percent. Our overall engagement favorability score from this group was 87 percent and our average favorability score on questions about the strength of our values was 85 percent. Another indicator we monitor to assess the strength of our company culture is voluntary turnover, which was 11 percent in 2023.

COMPETITIVE PAY & BENEFITS

We offer competitive compensation and benefits packages based on experience, knowledge and skill level that are designed to attract and retain talented employees and reward superior performance. Some of our benefits include paid parental leave, company match for retirement plans, comprehensive medical and dental coverage and paid time off.

SUPPORTING OUR COMMUNITIES

We operate in rural communities across North America, and we are proud to invest our time and money to help ensure they are thriving places to live and work. In 2023, we provided $6.2 million in charitable grants, partnerships, matching gifts, research support and in-kind giving to our communities, and our employees volunteered over 19,300 hours of their time to causes they care about. Through our companywide employee giving platform, we provide an easy way for all employees to donate to charities using payroll deduction, and we offer company match programs for both employee donations and volunteerism hours.

PROMOTING ENVIRONMENTAL EDUCATION

Drawing on more than a century of experience in sustainable forestry, we share our story and expertise through tours of our forests and facilities across North America, and we also operate two centers that are open to the public and provide a range of experiential opportunities to learn about forestry, ecology and environmental issues. In Washington, our Mount St. Helens Forest Learning Center is full of exhibits that tell the story of Mount St. Helens and the return of the forest through interactive, hands-on activities and visual displays. In North Carolina, our Cool Springs Environmental Education Center offers a 1,700-acre working forest and outdoor classroom for visitors to explore forestry working in harmony with wildlife habitat, air quality, water quality and recreational activities.

STRONG GOVERNANCE

Our corporate governance practices and policies promote the long-term interests of our shareholders, strengthen the accountability of our board of directors and management and help build public trust in our company. Our governance framework is built on a foundation of written policies and guidelines that align with the principles set out in the corporate governance framework established by the Investor Stewardship Group, or ISG, for U.S.-listed companies. We modify and enhance our policies and guidelines on a continuous basis to reflect changing best practices and legal requirements, as well as feedback from our shareholders. Following are summaries of some of our important governance practices.

BOARD COMPOSITION AND INDEPENDENCE

Our corporate governance guidelines and the listing requirements of the New York Stock Exchange (NYSE) require that a majority of the board be comprised of independent directors. Our current board composition far exceeds this requirement, as nine of our ten directors are independent, with the one exception being our chief executive officer. We have appointed eight new directors to our board since 2015. Four of our directors are women, including one woman of color, and two of our three key board committees are chaired by female directors. Our board has chosen to separate the positions of board chair and chief executive officer, which strengthens the board’s independent oversight of the company’s performance and governance standards. All of our directors stand for election annually, and we have a majority voting standard in uncontested elections. The board has regular executive sessions of independent directors, and the Audit, Compensation, and Governance and Corporate Responsibility Committees are all composed solely of independent directors in accordance with NYSE and SEC rules.

EXECUTIVE COMPENSATION

Our compensation program is designed to reflect a strong pay-for-performance alignment that will result in superior financial results and create long-term value for shareholders. The Compensation Committee completes a risk assessment of the company’s compensation program on an annual basis and also reviews the program and considers feedback from shareholders to ensure that compensation is appropriately linked to performance against company strategy and is aligned with the interests of our shareholders. Some of our leading executive compensation practices include:

SHARE OWNERSHIP REQUIREMENTS

We have share ownership requirements for our executive officers and directors that require each of them to hold a multiple of his or her base salary (or cash compensation) in shares of Weyerhaeuser stock. The minimum holding requirement is 6x base salary for our chief executive officer, 3x base salary, increased in 2023 from 2x base salary, for our senior vice presidents, and 5x annual cash retainer for our non-employee directors. Until the required ownership levels are achieved, executives must retain 75 percent of the net profit shares acquired when restricted stock units (RSUs) and performance share units (PSUs) vest. Net profit shares are shares remaining after payment of taxes upon vesting of the related equity award. A director may sell shares issuable upon vesting of RSUs only for purposes of paying the taxes due upon vesting but must otherwise hold 100 percent of the net shares granted to him or her until the ownership requirement has been satisfied. Our Compensation Committee monitors and confirms that our directors and officers are in compliance with these requirements. Additionally, we have an anti-hedging and trading policy which prohibits our directors, executive officers and employees who report directly to our executive officers from hedging their ownership of the company’s stock. The policy also prohibits directors and executive officers from pledging company stock, engaging in any short sales of company stock or trading company stock on margin.

CODE OF ETHICS

Integrity is a core value at Weyerhaeuser. We have a strong culture of ethics and integrity at every level of our company. Since our founding in 1900, we have consistently been recognized for our ethical business practices, compliance and high standards. In 2023, we were named for the 14th time as one of the World’s Most Ethical Companies® by Ethisphere Institute, a global leader in defining and advancing the standards of ethical business practices. Our Code of Ethics applies to all employees and members of our board, and it is an expression of our commitment and shared responsibility to conduct our business affairs ethically with stakeholders, including employees, communities, customers, suppliers, contractors and shareholders. Our employees also participate in regular compliance and ethics training, role-model and promote ethical behavior, and are instructed on how to communicate concerns of unethical behavior.

SHAREHOLDER ENGAGEMENT

We believe that maintaining regular and active dialogue with our shareholders is important for effective corporate governance as well as to our commitment to deliver sustainable, long-term value to our shareholders. We engage with our shareholders on a variety of topics throughout the year to ensure we are addressing questions and concerns, to seek input and to provide perspective on our policies and practices. Shareholder feedback is regularly reviewed and considered by the board and its committees and is reflected in adjustments and enhancements to our policies and practices. We remain committed to investing time with our shareholders to maintain transparency and to better understand their views on key issues.

SHAREHOLDER RIGHTS

Shareholder Proxy Access

Our company Bylaws allow eligible shareholders to nominate candidates to the board of directors who are included in the company’s proxy statement and ballot. This process for inclusion of shareholder nominees in the proxy statement is in addition to previously existing Bylaw provisions that allow shareholders to nominate directors to the board without access to the company’s proxy statement.

Shareholders' Right to Call Meetings

Our company Bylaws provide that special meetings of our shareholders may be called by shareholders representing at least 25 percent of the company’s outstanding shares if certain notice and other procedural requirements are followed and if the board determines that the matters of business to be brought before the meeting are appropriate for shareholder action under applicable law.

DISCIPLINED RISK MANAGEMENT

Making the right decisions for our business requires understanding risk. We use disciplined processes to manage our risks, which include, among other areas, environmental, safety, social, legal, operational and public-policy risks so our leaders and employees can make sound and

informed decisions. Our enterprise risk management group evaluates the likelihood of various risks and determines the potential magnitude of impact to our company. The analysis is conducted under the guidance of our chief compliance officer, who reports to our senior vice president and general counsel and our Governance and Corporate Responsibility Committee, with assistance from other members of the management team, and is reviewed by our board of directors. We also conduct internal audits regularly to ensure compliance with environmental, safety, financial, disclosure and other regulations; voluntary standards; and our own company policies. When noncompliance issues are identified, we develop, implement and track corrective action plans to ensure timely resolution. An independent public accounting firm audits our accounting processes, financial reporting and internal controls on an ongoing basis. We also focus on managing cybersecurity risk through a program that includes information security training, systems testing, testing and audit of our IT controls, and alignment of our program with the National Institute of Standards and Technology Cybersecurity Framework (see further discussion at Item 1C Cybersecurity). We also maintain and regularly update other company policies that guide our business, inform our employees and help manage our identified risks, including the following: Anti-Bribery Policy; Anti-Discrimination, Anti-Harassment and Equal Employment Opportunity Policy; Insider Trading Policy; Related Party Transactions Review and Approval Policy; Anti-Hedging and Trading Policy; Chemical Management Policy; Code of Ethics; Environmental Policy; Health and Safety Policy; Human Rights Policy; Product Stewardship Policy; Supplier Code of Ethics; Sustainable Forestry Policy; Threatened and Endangered Species Policy; and Wood Procurement Policy.

PARTICIPATING IN PUBLIC POLICY

Our ethical and transparent involvement in public policy includes coalition and relationship building, advocacy, political contributions and grassroots activities. As active members of our communities, we participate in the political process to help shape policy and legislation affecting our company and industry and do so without regard to the private political preferences of executives. All political contributions are managed by our government affairs team. Public policy and legislative priorities are reviewed annually with senior business leaders, our board of directors and our Governance and Corporate Responsibility Committee. We follow both the letter and the spirit of the laws governing lobbying. Our managers receive regular training on current laws and practices, and we work fairly and honestly with public officials at all levels. Some states allow companies to contribute directly to campaigns for state and local offices and for ballot measures. We file these contributions as required at state and local levels. We also sponsor a U.S. Weyerhaeuser Political Action Committee (WPAC), which solicits voluntary contributions from eligible shareholders, employees and our board of directors. WPAC contribution reports are filed with the Federal Election Commission, and we provide a summary of our annual WPAC political donations in the sustainability section of our website.

WHAT WE DO

This section provides information about how we:

For each of our business segments, we provide details about what we do, where we do it, how much we sell and where we are headed.

TIMBERLANDS

Our Timberlands segment manages 10.5 million acres of private commercial timberlands in the U.S. We own 9.8 million of those acres and control the remaining acres through long-term contracts. In addition, we have renewable, long-term licenses on 14.1 million acres of Canadian timberlands.

WHAT WE DO

Forestry Management

Our Timberlands segment:

We seek to maximize the returns from our timberlands by selling delivered logs and through stumpage sales to both internal and external customers. We leverage our expertise in forestry using research and planning systems to optimize log production and innovative planting and harvesting techniques across varying terrain. We use intensive, customized silviculture to increase forest productivity and returns while managing our forests on a sustainable basis. We use our scale, infrastructure and supply chain expertise to deliver reliable and consistent supply to our customers.

Competitive factors within each of our market areas generally include price, species, grade, quality, proximity to wood-consuming facilities and the ability to consistently meet customer requirements. We compete in the marketplace through our ability to provide customers with a consistent and reliable supply of high-quality logs at scale volumes and competitive prices. Our customers also value our status as a SFI certified supplier.

Sustainable Forestry Practices

We manage our forests intensively to maximize the value of every acre and produce a sustainable supply of wood fiber for our customers. At the same time, we are careful to protect biological diversity, water quality and other ecosystem values. Our working forests also provide unique environmental, cultural, historical and recreational value. We work hard to protect these and other qualities, while still managing our forests to produce financially mature timber. We follow regulatory requirements, voluntary standards and certify 100 percent of our North American timberlands under the SFI Forest Management Standard.

Canadian Forestry Operations

In Canada, we manage timberlands under long-term licenses that serve as the primary source of raw material for our manufacturing facilities in various provinces. When we harvest trees, we pay the provinces at stumpage rates set by the government. We transfer logs to our manufacturing facilities at cost and do not generate any significant profit from the harvest of timber from our licensed acres in Canada.

Timberlands Products

HOW WE MEASURE OUR PRODUCTS

We use multiple units of measure when transacting business including:

We report Timberlands volumes in ton equivalents.

WHERE WE DO IT

As of December 31, 2023, we sustainably managed timberlands in 17 states. This included owned or contracted acres in the following locations:

In Canada, we manage timberlands under long-term licenses that provide raw material for our manufacturing facilities. These licenses are in Alberta, British Columbia, Ontario and Saskatchewan.

Our total timber inventory — comprised of timber on owned and contracted land in the U.S. — is approximately 594 million tons. This timber inventory does not translate into a specific amount of lumber or panel products because the quantity of end products varies according to the age, species, size and quality of the timber and will change over time as these variables adjust.

We maintain our timber inventory in an integrated resource inventory system and geographic information system (GIS). The resource inventory component of the system is proprietary and is largely based on internally developed methods, including growth and yield models developed by our research and development organization. The GIS component is based on GIS software that is viewed as the standard in our industry.

Timber inventory data collection and verification techniques include the use of industry standard field sampling procedures as well as proprietary remote sensing technologies in some geographies. The data is collected and maintained at the timber stand level.

We also own and operate nurseries and seed orchards in Alabama, Arkansas, Georgia, Louisiana, Mississippi, Oregon, South Carolina and Washington.
