Malissa Webber | Rochester Nursery, Wash. Dear Fellow Shareholder, Our company delivered a solid performance in 2023 against a backdrop of challenging macroeconomic and market conditions. Despite these headwinds, our teams demonstrated tremendous resilience and executed remarkably well across all our businesses. We remained focused on serving our customers and driving meaningful improvements across each of the value levers of our investment thesis. We enhanced our unmatched portfolio of assets, delivered industry- leading performance, advanced our strong ESG foundation and again demonstrated our commitment to disciplined capital allocation. I am incredibly proud of everything we accomplished in 2023 to make Weyerhaeuser a stronger and better company and position us to drive long-term value for our shareholders.

Notably, we completed strategic acquisitions in the Carolinas and Mississippi to further optimize and improve our Southern Timberlands portfolio with high-quality, highly productive acreage that is well integrated with our existing operations. To date, we have deployed approximately $530 million against our target to grow our Timberlands portfolio through $1 billion of disciplined investments through 2025. In addition, we recently launched a small parcel acquisitions program that will help to further grow our Timberlands footprint through strategic smaller transactions. We also opened our newest export yard in South Carolina in 2023 and established new customer relationships in India, increasing deliveries into that market by 25 percent. In our Wood Products business, we continued to make disciplined investments across our manufacturing operations, resulting in high-return projects that reduce costs, improve productivity, increase recovery and position Weyerhaeuser to further improve our peer- leading performance. DELIVERING INDUSTRY-LEADING RESULTS IN CHALLENGING MARKETS Despite managing through a variety of market headwinds in 2023, our teams collectively delivered net earnings of $839 million and Adjusted EBITDA* of $1.7 billion. Through our relentless focus on operational excellence (OpX), cost focus and continuous improvement, each of our Wood Products manufacturing businesses delivered peer-leading Adjusted EBITDA margins in 2023, and our Western Timberlands business held the top position (cid:76)(cid:81)(cid:3)(cid:36)(cid:71)(cid:77)(cid:88)(cid:86)(cid:87)(cid:72)(cid:71)(cid:3)(cid:40)(cid:37)(cid:44)(cid:55)(cid:39)(cid:36)(cid:3)(cid:68)(cid:81)(cid:71)(cid:3)(cid:70)(cid:68)(cid:86)(cid:75)(cid:3)(cid:193)(cid:82)(cid:90)(cid:3)(cid:83)(cid:72)(cid:85)(cid:3)(cid:68)(cid:70)(cid:85)(cid:72)(cid:17)(cid:3)(cid:55)(cid:75)(cid:72)(cid:86)(cid:72)(cid:3)(cid:50)(cid:83)(cid:59)(cid:3) efforts helped us capture an additional $37 million in margin improvements across our businesses. These are solid results and a powerful testament to the hard work our teams have invested to be best in class and deliver superior performance across business cycles.

LEADING ON NATURAL CLIMATE SOLUTIONS We achieved an important milestone in 2023 with (cid:87)(cid:75)(cid:72)(cid:3)(cid:68)(cid:83)(cid:83)(cid:85)(cid:82)(cid:89)(cid:68)(cid:79)(cid:3)(cid:82)(cid:73)(cid:3)(cid:82)(cid:88)(cid:85)(cid:3)(cid:192)(cid:85)(cid:86)(cid:87)(cid:3)(cid:73)(cid:82)(cid:85)(cid:72)(cid:86)(cid:87)(cid:3)(cid:70)(cid:68)(cid:85)(cid:69)(cid:82)(cid:81)(cid:3)(cid:83)(cid:85)(cid:82)(cid:77)(cid:72)(cid:70)(cid:87)(cid:3)(cid:68)(cid:81)(cid:71)(cid:3) (cid:80)(cid:82)(cid:81)(cid:72)(cid:87)(cid:76)(cid:93)(cid:68)(cid:87)(cid:76)(cid:82)(cid:81)(cid:3)(cid:82)(cid:73)(cid:3)(cid:82)(cid:88)(cid:85)(cid:3)(cid:192)(cid:85)(cid:86)(cid:87)(cid:3)(cid:70)(cid:85)(cid:72)(cid:71)(cid:76)(cid:87)(cid:86)(cid:17)(cid:3)(cid:55)(cid:75)(cid:76)(cid:86)(cid:3)(cid:90)(cid:68)(cid:86)(cid:3)(cid:68)(cid:3)(cid:86)(cid:76)(cid:74)(cid:81)(cid:76)(cid:192)(cid:70)(cid:68)(cid:81)(cid:87)(cid:3) step forward — one that not only demonstrates our commitment to offering only the highest-integrity credits to the market, but that also positions Weyerhaeuser as a reputable and scalable climate-solutions provider as others work to reduce their carbon footprint. We have several additional carbon projects in the pipeline, and we are well-positioned for long-term growth in these emerging markets, including by leveraging our unique subsurface ownership in the U.S. South to meet growing demand and investments in carbon capture and sequestration. In addition, we continued to scale our renewable energy business in 2023. We currently have six active wind projects and more than 50 agreements in place for solar projects across our U.S. land base. Overall, we have increased Natural Climate Solutions Adjusted EBITDA by 114 percent since 2020, and we remain focused on growing this business to $100 million of Adjusted EBITDA by year-end 2025. With the work we’ve already completed, and the prospects of advancing these opportunities across our expansive timber holdings, we believe there is no other company with the capabilities or asset base to deliver on this value-creation opportunity, at scale, like Weyerhaeuser. SERVING OUR CUSTOMERS We continued building on the service and technology solutions we provide our customers in 2023. As part of a broader project to revamp our Wood Products go-to-market strategy, we created Sales Enablement and Customer Experience teams in 2023, and we launched an enhanced online portal for customers. In Timberlands, we continued to leverage our scale and supply chain expertise to provide a reliable, consistent supply of high-quality logs to our customers. All these efforts have strengthened customer relationships and improved organizational alignment, pricing optimization, market agility, new product development and overall sales effectiveness. We continue to build on our competitive advantage and the quality of service we provide customers — putting us in the best possible position to earn and grow their business over the long term. BUILDING ON OUR SUSTAINABILITY LEADERSHIP We have been a global leader in sustainable forestry for more than a century, and we continued to make progress on our sustainability goals and strengthen our overall ESG leadership in 2023. We are the only company in our sector “We have been a global leader in sustainable forestry for more than a century.” (cid:45)(cid:82)(cid:71)(cid:92)(cid:3)(cid:45)(cid:82)(cid:69)(cid:68)(cid:81)(cid:72)(cid:78)(cid:16)(cid:54)(cid:88)(cid:76)(cid:87)(cid:72)(cid:85)(cid:3)(cid:3)(cid:95)(cid:3)(cid:3)(cid:54)(cid:83)(cid:85)(cid:76)(cid:81)(cid:74)(cid:192)(cid:72)(cid:79)(cid:71)(cid:3)(cid:55)(cid:85)(cid:72)(cid:72)(cid:3)(cid:41)(cid:68)(cid:85)(cid:80)(cid:15)(cid:3)(cid:50)(cid:85)(cid:72)(cid:17) (cid:48)(cid:76)(cid:78)(cid:72)(cid:3)(cid:37)(cid:68)(cid:74)(cid:79)(cid:72)(cid:92)(cid:3)(cid:95)(cid:3)(cid:38)(cid:82)(cid:87)(cid:87)(cid:68)(cid:74)(cid:72)(cid:3)(cid:42)(cid:85)(cid:82)(cid:89)(cid:72)(cid:15)(cid:3)(cid:50)(cid:85)(cid:72)(cid:17) (cid:45)(cid:88)(cid:71)(cid:71)(cid:3)(cid:45)(cid:82)(cid:81)(cid:72)(cid:86)(cid:3)(cid:95)(cid:3)(cid:54)(cid:87)(cid:17)(cid:3)(cid:43)(cid:72)(cid:79)(cid:72)(cid:81)(cid:86)(cid:3)(cid:55)(cid:85)(cid:72)(cid:72)(cid:3)(cid:41)(cid:68)(cid:85)(cid:80)(cid:15)(cid:3)(cid:58)(cid:68)(cid:86)(cid:75)(cid:17) listed on the Dow Jones Sustainability North America Index, and we continued to lead our industry on carbon accounting and disclosures, demonstrating through our award-winning Carbon Record that our company removes far more CO2 than we emit through our operations each year. We also made progress against our 2030 greenhouse gas emissions reduction targets and are on track to achieve net-zero emissions by 2040, and we continue to advance our 3 by 30 Sustainability Ambitions around contributing to climate solutions, sustainable homes and the long-term health and resilience of our rural operating communities. AMPLIFYING OUR COMMUNITY IMPACT Citizenship has been foundational to our company and culture at Weyerhaeuser from the early days of our company. In 2023, we provided $6.2 million in charitable grants, partnerships, matching gifts, research support and in-kind giving to our communities across North America. Our employees participated in nearly 700 community projects and volunteered more than 19,000 hours of their time. We also launched two new signature programs to further enhance the level of support we provide our rural (cid:70)(cid:82)(cid:80)(cid:80)(cid:88)(cid:81)(cid:76)(cid:87)(cid:76)(cid:72)(cid:86)(cid:17)(cid:3)(cid:55)(cid:75)(cid:72)(cid:3)(cid:192)(cid:85)(cid:86)(cid:87)(cid:15)(cid:3)(cid:55)(cid:43)(cid:53)(cid:44)(cid:57)(cid:40)(cid:15)(cid:3)(cid:76)(cid:81)(cid:89)(cid:82)(cid:79)(cid:89)(cid:72)(cid:86)(cid:3)(cid:68)(cid:3)(cid:70)(cid:82)(cid:80)(cid:80)(cid:76)(cid:87)(cid:80)(cid:72)(cid:81)(cid:87)(cid:3)(cid:87)(cid:82)(cid:3) (cid:76)(cid:81)(cid:89)(cid:72)(cid:86)(cid:87)(cid:3)(cid:7)(cid:24)(cid:3)(cid:80)(cid:76)(cid:79)(cid:79)(cid:76)(cid:82)(cid:81)(cid:3)(cid:68)(cid:70)(cid:85)(cid:82)(cid:86)(cid:86)(cid:3)(cid:192)(cid:89)(cid:72)(cid:3)(cid:82)(cid:73)(cid:3)(cid:82)(cid:88)(cid:85)(cid:3)(cid:82)(cid:83)(cid:72)(cid:85)(cid:68)(cid:87)(cid:76)(cid:81)(cid:74)(cid:3)(cid:70)(cid:82)(cid:80)(cid:80)(cid:88)(cid:81)(cid:76)(cid:87)(cid:76)(cid:72)(cid:86)(cid:3) that are in most need of extra support. Second is a program called Learn Local, Earn Local, which focuses on youth education and workforce development. These are two of the more ambitious community programs we have launched in years, and we look forward to building on the positive impact we have in our communities and helping ensure they remain thriving places to live and do business. SUPPORTING AND INVESTING IN OUR PEOPLE Providing a safe and rewarding work environment for our people is fundamental to our culture at Weyerhaeuser, and we have made comprehensive investments in our training and leadership development programs over the past several years. In 2023, we rolled out new front-line leader safety training focused on helping leaders have more effective safety conversations with their teams, and we also expanded environmental training for Wood Products manufacturing leadership. In terms of promoting career growth, more than 300 leaders participated in our three signature leadership development programs, we piloted a new companywide mentoring program, and our employees spent more than 50,000 hours receiving a variety of online, virtual and classroom training in 2023. We also rolled out a new roadmap for our diversity, equity and inclusion work in 2023, strengthening alignment around our goals and strategy and helping us build a more diverse and inclusive environment at every level of the company. We delivered inclusion training to more than 300 leaders, launched three new employee resource groups (ERGs) and nearly doubled our companywide membership across all ERGs. We are committed to advancing this work and helping everyone in our company understand the importance of DE&I to our long-term success. RETURNING CASH TO SHAREHOLDERS ACROSS BUSINESS CYCLES We continued to showcase the power of our cash return framework in 2023. Despite challenging market conditions, we demonstrated that our framework is both sustainable and appropriate for the company’s portfolio (cid:68)(cid:81)(cid:71)(cid:3)(cid:87)(cid:75)(cid:72)(cid:3)(cid:70)(cid:68)(cid:86)(cid:75)(cid:3)(cid:193)(cid:82)(cid:90)(cid:3)(cid:90)(cid:72)(cid:3)(cid:74)(cid:72)(cid:81)(cid:72)(cid:85)(cid:68)(cid:87)(cid:72)(cid:3)(cid:73)(cid:85)(cid:82)(cid:80)(cid:3)(cid:82)(cid:88)(cid:85)(cid:3)(cid:69)(cid:88)(cid:86)(cid:76)(cid:81)(cid:72)(cid:86)(cid:86)(cid:3)(cid:68)(cid:70)(cid:85)(cid:82)(cid:86)(cid:86)(cid:3) market cycles. In 2023, we generated Adjusted Funds Available for Distribution (Adjusted FAD)* of $986 million and returned $783 million of total cash to shareholders based on 2023 results, or approximately 80 percent of our Adjusted FAD. This included $556 million paid WEYERHAEUSER COMPANY > 2023 ANNUAL REPORT AND FORM 10-K Jacob Schuler | Holden, La.

Importantly, we funded our supplemental dividend and share repurchases within our framework and required no balance sheet or portfolio actions to cover our return commitment. Given the design of our framework, we retain 20 to 25 percent of our Adjusted FAD annually, which can be utilized as we evaluate future capital allocation actions, including strategic growth opportunities.

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. This portion of our Annual Report on Form 10-K provides detailed information about who we are and what we do. Unless otherwise specified, current information reported in this Form 10-K is as of or for the fiscal year ended December 31, 2023. Throughout this Form 10-K, unless specified otherwise, references to “we,” “our,” “us” and “the company” refer to the consolidated company. We break out financial information such as revenues, earnings and assets by the business segments that comprise our company. We also discuss the geographic areas where we do business. WE CAN TELL YOU MORE AVAILABLE INFORMATION We meet the information reporting requirements of the Securities Exchange Act of 1934 by filing periodic reports (annual reports on Form 10-K, quarterly reports on Form 10-Q), current reports on Form 8-K, proxy statements and other information with the Securities and Exchange Commission (SEC). These reports and statements, which contain information about our business, financial results, corporate governance and other matters, as well as amendments to these reports and statements, are available at: •the SEC website — www.sec.gov and •our website (free of charge) — www.weyerhaeuser.com. When we file or furnish information electronically with the SEC, it is also posted to our website. 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. WEYERHAEUSER COMPANY > 2023 ANNUAL REPORT AND FORM 10-K 1 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: •Timberlands; •Real Estate, Energy and Natural Resources (Real Estate & ENR) and •Wood Products. 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: •Timberlands — Capture maximum timber value from every acre we own or manage. •Real Estate & ENR — Deliver premiums to timberland value by identifying and monetizing higher and better use lands and capturing the full value of surface and subsurface assets. •Wood Products — Manufacture high-quality structural lumber, oriented strand board and engineered wood products, as well as deliver complementary building products for residential, multi-family, industrial and light commercial applications at competitive costs. 2 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 WEYERHAEUSER COMPANY > 2023 ANNUAL REPORT AND FORM 10-K 3 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. 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. 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 4 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: SEGMENT Timberlands Real Estate & ENR Wood Products Corporate Total SAFETY NUMBER OF EMPLOYEES 1,282 66 7,151 819 9,318 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: •caring leadership with a safety-focused “tone at the top”; •robust safety policies and practices; •engaged employees with regular safety training and education and •a strong companywide focus on identifying and reducing hazards and risks. 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: •partner with our employees on individual development plans and provide a wide range of individual development tools; •annually enroll hundreds of our front-line, mid-level and executive leaders (future and current) in development programs; •engage in rigorous internal talent assessment and succession planning and •monitor and regularly review our strategies and action plans to address any workforce gaps in our organization, including gender, race and other underrepresented groups. 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 WEYERHAEUSER COMPANY > 2023 ANNUAL REPORT AND FORM 10-K 5 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. 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: •“no tolerance” policies regarding discrimination and harassment of employees, suppliers, customers and visitors; •recurrent reviews of pay equity and addressing of gaps; •paid parental leave for all employees; •masked names on resumes and diverse hiring teams; •training on unconscious bias and harassment prevention; •inclusive leadership training integrated into our development programs; •employee-led resource groups; •ongoing companywide communication on the importance of inclusion and •regular companywide surveys and other means of anonymously collecting candid feedback to assist us in evaluating our inclusive culture and addressing any identified gaps. 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 6 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: •balanced focus on both long-term strategic and financial objectives and shorter-term business objectives, with significant weighting of pay tied to performance-based compensation and a material portion of compensation in the form of equity awards with multi-year vesting; •“double trigger” accelerated vesting of our long-term incentive equity awards upon a change of control; •incentive compensation recovery policy that requires the Compensation Committee to pursue recovery of incentive compensation received by executive officers in the event of a restatement of the company’s financial statements, subject to narrowly defined exceptions and •limited executive perquisites such as relocation-related benefits, security services on an “as needed” basis and annual executive health screenings. 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 WEYERHAEUSER COMPANY > 2023 ANNUAL REPORT AND FORM 10-K 7 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 8 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: •grow and harvest trees, •maximize the value of every acre we own and •manufacture and sell wood products. 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: •grows and plants seedlings to reforest harvested areas using the most effective regeneration method for the site and species (natural regeneration is employed and managed in parts of Canada and the northern U.S.); •manages our timberlands as the trees grow to maturity; •harvests trees to be converted into wood products, such as lumber, oriented strand board, engineered wood products, pellets, pulp and paper; •manages the health of our forests to sustainably maximize harvest volumes, minimize risks, and protect unique environmental, cultural, historical and recreational value and •offers recreational access. 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 PRODUCTS HOW THEY’RE USED Delivered logs: • Grade logs • Fiber logs Timber Grade logs are made into lumber, plywood, veneer and other products used in residential homes, commercial structures, furniture, industrial and decorative applications. Fiber logs are sold to pulp, paper and oriented strand board mills to make products used for printing, writing, packaging, homebuilding and consumer products, as well as into renewable energy and pellets. Standing timber is sold to third parties through stumpage sales. Recreational leases Timberlands are leased or permitted for recreational purposes. Other products Seeds and seedlings grown in the U.S. and wood chips. WEYERHAEUSER COMPANY > 2023 ANNUAL REPORT AND FORM 10-K 9 HOW WE MEASURE OUR PRODUCTS Summary of 2023 Standing Timber Inventory We use multiple units of measure when transacting business including: GEOGRAPHIC AREA MILLIONS OF TONS AT DECEMBER 31, 2023 TOTAL INVENTORY(1) •Thousand board feet (MBF) — used in the West to measure the expected lumber recovery from a tree or log and •Green tons (GT) — used in the South to measure weight; factors used for conversion to product volume can vary by species, size, location and season. 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: •2.5 million acres in the western U.S. (Oregon and Washington); •6.8 million acres in the southern U.S. (Alabama, Arkansas, Florida, Georgia, Louisiana, Mississippi, North Carolina, Oklahoma, South Carolina, Texas and Virginia) and •1.2 million acres in the northern U.S. (Maine, New Hampshire, Vermont and West Virginia).

Oregon Washington Total West South Alabama Arkansas Florida Georgia Louisiana Mississippi North Carolina Oklahoma South Carolina Texas Virginia 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. 10 We provide a year-round flow of logs to internal and external customers. We sell grade and fiber logs to manufacturers that produce a diverse range of products. We also sell standing timber to third parties and lease land for recreational purposes. Most of our timberlands are strategically located to take advantage of road, logging and transportation systems for efficient delivery of logs to customers. Western United States Our Western timberlands are well situated to serve the wood products and pulp markets in Oregon and Washington. For the year ended December 31, 2023, we sold 33 percent of our total Western log sales volume internally. Additionally, our location on the West Coast provides access to higher-value export markets for Douglas fir and whitewood logs to Japan, China and Korea. Our largest export market is Japan, where Douglas fir is a preferred species for higher-valued post and beam homebuilding. The size and quality of our Western timberlands, coupled with their proximity to several deep-water port facilities, competitively positions us to meet the needs of Pacific Rim log markets. Our holdings are composed primarily of Douglas fir, a species highly valued for its structural strength, stiffness and appearance. Most of our lands are located on the west side of the Cascade Mountain Range with soil and rainfall conditions considered favorable for growing this species. Our standing timber inventory is comprised of 81 percent Douglas fir, 12 percent whitewood and 7 percent hardwood. Our management systems and supply chain expertise provide us with a competitive operating advantage in a number of areas including forestry and research, harvesting, marketing and logistics. Additionally, our scale, diversity of timberlands ownership and infrastructure on the West Coast allow us to consistently and reliably supply logs to our internal and external customers year-round. 2023 Western U.S. Inventory by Age / Species MILLIONS OF TONS 60 50 40 30 20 10 0 AGE (in years) 0–9 10–19 20–29 30–39 40–49 50–59 60–89 90–134 135+ DOUGLAS FIR/CEDAR WHITEWOOD HARDWOOD Note: Inventory charted includes all conservation and non-harvestable areas.

Northern United States Our Northern timberlands acres contain a diverse mix of temperate broadleaf hardwoods and mixed conifer species across timberlands located in four states. We grow over 40 species and market over 300 product grades to a diverse mix of customers. Our large-diameter cherry, red oak and hard maple sawlogs and veneer logs serve domestic and export furniture markets. Our maple and other appearance woods are used in furniture and high-value decorative applications. In addition to high-value hardwood sawlogs, our log mix includes hardwood fiber logs for pulp and oriented strand board applications. Hardwood pulpwood is a significant market in the Northern region and we have long-term supply agreements, primarily at market rates, for nearly 91 percent of our hardwood pulp production. Our competitive advantages include a merchandising program to capture the value of premium hardwood logs. 2023 Northern U.S. Inventory by Species CONIFER HARDWOOD 39% 61% The average age of timber harvested from our Northern timberlands in 2023 was 60 years. Timber harvested in the North is sold predominantly as delivered logs to domestic mills, including our manufacturing facilities. For the year ended December 31, 2023, we sold 10 percent of our total Northern log sales volume internally. In accordance with our sustainable forestry practices, we harvest an average of 1 percent of our acreage each year in the North. Regeneration is predominantly natural, augmented by planting where appropriate. Canada — Licensed Forestlands We manage forestlands in Canada under long-term licenses from the provincial governments to secure volume for our manufacturing facilities in various provinces. The provincial governments regulate the volume of timber that may be harvested each year through Annual Allowable Cuts (AAC), which are updated every 10 years. As of December 31, 2023, our AAC by province was: •Alberta — 2,211 thousand tons, •British Columbia — 547 thousand tons, •Ontario — 154 thousand tons and •Saskatchewan — 633 thousand tons. When the volume is harvested, we pay the province for that volume at stumpage rates set by the government. The harvested logs are transferred to our manufacturing facilities at cost (stumpage plus harvest, haul and overhead costs less any margin on selling logs to third parties). Any profit from harvesting the log through converting to finished products is recognized at the respective mill in our Wood Products segment. 12 Summary of License Arrangements HOW MUCH WE SELL GEOGRAPHIC AREA Province: Alberta British Columbia Ontario(1) Saskatchewan(1) Total Canada (1) License is managed by partnership.

WHERE WE’RE HEADED Our competitive strategies include: •continuing to capitalize on our scale of operations, silviculture and supply chain expertise and sustainability practices; •improving cash flow through operational excellence initiatives including merchandising for value, harvest and transportation efficiencies as well as focused silviculture investments to improve forest productivity; •optimizing and growing our timber portfolio through disciplined investments; •leveraging our export and domestic market access, infrastructure and strong customer relationships; •increasing our recreational lease revenue and •continuing to maximize the value of our timberlands portfolio by managing the acres to achieve the highest and best use. REAL ESTATE, ENERGY AND NATURAL RESOURCES Our Real Estate & ENR segment maximizes the value of our timberland ownership through application of our asset value optimization (AVO) process and captures the full value of surface and subsurface assets. In 2021, we launched our natural climate solutions business through which we leverage our resources and expertise to help others meet their goals to reduce carbon emissions or mitigate environmental impacts. This involves an expansion of our established business activities in the areas of conservation, mitigation banking and leasing land for renewable energy projects. Additionally, it involves advancing our participation in two emerging markets focused on the mitigation of carbon emissions: forest carbon, by which we generate carbon credits through incremental carbon sequestration over a baseline and sell them on voluntary carbon markets, and carbon capture and storage, which involves leasing of surface and subsurface ownership to safely and permanently sequester transported carbon emissions from their source. As the largest private owner of timberlands in North America, the scale and geographic diversity of our assets create a unique opportunity for participation in each of these activities, all of which offer natural solutions for reducing carbon emissions and support climate change mitigation efforts. WHAT WE DO Real Estate Properties that exhibit higher use value than commercial timberlands are monetized by our Real Estate business over time. We analyze our existing U.S. timberland holdings using a process we call AVO. We start with understanding the value of a parcel operating as commercial timberlands and then assess the specific real estate attributes of the parcel and its corresponding market. The assessment includes demographics, infrastructure and proximity to amenities and recreation to determine the potential to realize a premium value to commercial timberland. Attributes can evolve over time, and accordingly, the assignment of value and opportunity can change. We continually revisit our AVO assessment for all our timberland acres. Recently, we have been focused on developing a next-generation process that enhances our ability to identify and capture value from various timber and non-timber attributes, including carbon, renewable energy and other natural climate solutions opportunities. This sophisticated technology-enabled approach, referred to as “AVO 2.0”, leverages remote sensing, satellite imagery, machine learning and other advanced data analytics, and has driven significant improvements in our ability to identify strategic growth opportunities and manage every acre in our portfolio to maximize value across the full suite of attributes and opportunities. We expect to sell certain properties for recreational, conservation, commercial or residential purposes over time. We will also entitle a small amount of acres for real estate development. Development, outside of entitlement activities, is typically performed by third parties. Mitigation banking consists of setting 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. Activities within the Real Estate business that contribute to natural climate solutions include conservation sales or easements and mitigation banking. Some of our real estate activities are conducted through our TRSs. Occasionally, we sell a small amount of timberland acreage in areas where we choose to reduce our market presence and capture a price that exceeds the value derivable from holding and operating as commercial timberlands. These transactions will vary based on factors including the location and physical and operating characteristics of the timberlands. The volume of real estate sales is a function of many factors, including the general state of the economy, demand in local real estate markets, the ability of buyers to obtain financing, the number of competing properties listed for sale, the seasonal nature of sales, the plans of adjacent landowners, our expectation of future price appreciation, the timing of harvesting activities and the availability of government and not-for-profit funding. In any period, the average price per acre sold will vary based on the location and physical characteristics of parcels sold. Energy and Natural Resources We focus on maximizing potential opportunities for construction materials, industrial minerals, renewable energy (including wind WEYERHAEUSER COMPANY > 2023 ANNUAL REPORT AND FORM 10-K 15 and solar energy), natural gas, rights of way easements on our timberland portfolio and retained mineral interests. Activities within the ENR business that contribute to natural climate solutions include utilizing land for the production of renewable energy like wind and solar, forest carbon and carbon capture and storage. As the owner of mineral rights and interests, we typically do not invest in development or operations but, instead, enter into contracts with operators granting them the rights to explore, develop and sell energy and natural resources produced from our property in exchange for rents and royalties. We generally reserve mineral rights when selling timberlands acreage. Some Energy and Natural Resources activities are conducted through our TRSs.

We also participate in voluntary certification of our timberlands to ensure that we sustain their overall quality, including the protection of wildlife and water quality. Changes in law and regulation, or certification standards, can significantly affect our business. REGULATIONS AFFECTING FORESTRY PRACTICES In the United States, regulations established by federal, state and local government agencies to protect, among other things, water quality, wetlands and other wildlife habitat could affect future harvests and forest management practices on our timberlands. Forest practice laws and regulations that affect present or future harvest and forest management activities in certain states include: •limits on the size of clearcuts, •requirements that some timber be left unharvested to protect water quality and fish and wildlife habitat, •regulations regarding construction and maintenance of forest roads, •rules requiring reforestation following timber harvest, •regulations on the use of pesticides and herbicides and •various related permit programs. Each state in which we own timberlands has developed best management practices and regulations to reduce the effects of forest practices on water quality and aquatic habitats. Additional and more stringent regulations may be adopted by various state and local governments to achieve water quality standards, protect fish and wildlife habitats, human health, or achieve other public policy objectives. In Canada, our forest operations are carried out on public timberlands under forest licenses with the provinces. All forest operations in Canada are subject to: •forest practices and environmental regulations and •license requirements established by contract between us and the relevant province designed to protect environmental values and encourage other stewardship values. In Canada, 21 member companies of the Forest Products Association of Canada (FPAC), including Weyerhaeuser’s Canadian subsidiary, announced in May 2010 the signing of a Canadian Boreal Forest Agreement (CBFA) with nine environmental organizations. The CBFA applies to approximately 72 million hectares of public forests licensed to FPAC members and, when fully implemented, was expected to lead to the conservation of significant areas of Canada’s boreal forest and protection of boreal species at risk, in particular, woodland caribou. While the CBFA mandate came to an end in 2017, CBFA signatories continue to work on management plans with provincial governments and seek the participation of indigenous and local communities in advancing the goals of the CBFA. ENDANGERED SPECIES PROTECTIONS In the United States, a number of fish and wildlife species that inhabit geographic areas near or within our timberlands have been listed as threatened or endangered under the federal Endangered Species Act (ESA) or similar state laws, including but not limited to: •the northern spotted owl, the marbled murrelet, a number of salmon species, bull trout and steelhead trout in the Pacific Northwest; •several freshwater mussel and sturgeon species and •the red-cockaded woodpecker, gopher tortoise, dusky gopher frog, American burying beetle and Northern long-eared bat in the South or Southeast. Additional species or populations may be listed as threatened or endangered as a result of pending or future citizen petitions or petitions initiated by federal or state agencies. In addition, significant citizen litigation seeks to compel the federal agencies to designate “critical habitat” for ESA-listed species, and many cases have resulted in settlements under which designations will be implemented over time. Such designations may adversely affect some management activities and options. Restrictions on timber harvests can result from: •federal and state requirements to protect habitat for threatened and endangered species; •regulatory actions by federal or state agencies to protect these species and their habitat and •citizen suits under the ESA. Such actions could increase our operating costs and affect timber supply and prices in general. To date, we do not believe that these measures have had, and we do not believe that in 2024 they will have, a significant effect on our harvesting operations. We anticipate that likely future actions will not disproportionately affect Weyerhaeuser as compared with comparable operations of U.S. competitors. In Canada: •The federal Species at Risk Act (SARA) requires protective measures for species identified as being at risk and for their critical habitat. Pursuant to SARA, Environment Canada continues to identify and assess species deemed to be at risk and their critical habitat. •In October 2012, the Canadian Minister of the Environment released a strategy for the recovery of the boreal population of woodland caribou under the SARA. The population and WEYERHAEUSER COMPANY > 2023 ANNUAL REPORT AND FORM 10-K 21 distribution objectives for boreal caribou across Canada are to (1) maintain the current status of existing, self-sustaining local caribou populations and (2) stabilize and achieve self- sustaining status for non-self-sustaining local caribou populations. Critical habitat for boreal caribou is identified for all boreal caribou ranges, except for northern Saskatchewan’s Boreal Shield range (SK1) where additional information is required for that population. Species assessment and recovery plans are developed in consultation with indigenous communities and stakeholders. •In 2017, the provinces were required to update the federal government on any progress associated with their draft caribou range plans. The majority of these plans are now being developed under Species at Risk Conservation agreements, signed between the provinces and the Federal Ministry. These agreements set out goals, objectives and timelines for caribou management. The identification and protection of habitat and the implementation of range plans and land use action plans may, over time, result in additional restrictions on timber harvests and other forest management practices that could increase operating costs for operators of timberlands in Canada. To date, we do not believe that these Canadian measures have had, and we do not believe that in 2024 they will have, a significant effect on our harvesting operations. We anticipate that likely future measures will not disproportionately affect Weyerhaeuser as compared with similar operations of Canadian competitors. FOREST CERTIFICATION STANDARDS We operate in North America under the Sustainable Forestry Initiative®(SFI). This is a certification standard designed to supplement government regulatory programs with voluntary landowner initiatives to further protect certain public resources and values. SFI is an independent standard, overseen by a governing board consisting of: •environmental sector, including non-profit environmental and conservation organizations, •social sector, including community and social interest groups, and •economic sector, including industry and landowner representatives. Ongoing compliance with SFI may result in some increases in our operating costs and reduction of our timber harvests in some areas. There is also competition from other private certification systems, primarily the Forest Stewardship Council (FSC), coupled with efforts by supporters to further those systems by persuading customers of forest products to require products certified to their preferred system. Certain features of the FSC system could impose additional operating costs on 22 timberland management. Because of the considerable variation in FSC standards, and variability in how those standards are interpreted and applied, if sufficient marketplace demand develops for products made from raw materials sourced from forests certified to these or other non-SFI standards, we could incur substantial additional costs for operations or need to reduce harvest levels in order to comply with such standards. WHAT THESE REGULATIONS AND CERTIFICATION PROGRAMS MEAN TO US The regulatory and non-regulatory forest management programs described above have: •increased our operating costs; •resulted in changes in the value of timber and logs from our timberlands; •contributed to increases in the prices paid for wood products and wood chips during periods of high demand; •sometimes made it more difficult for us to respond to rapid changes in markets, extreme weather or other unexpected circumstances and •potentially encouraged further reductions in the use of, or substitution of other products for, lumber, oriented strand board, engineered wood products and plywood. We believe that these regulations and programs have not had, and in 2024 will not have, a significant effect on our total harvest of timber in the United States or Canada. However, these kinds of programs may have such an effect in the future. We expect we will not be disproportionately affected by these programs as compared with typical owners of comparable timberlands. We also expect that these programs will not significantly disrupt our planned operations over large areas or for extended periods. CANADIAN INDIGENOUS RIGHTS Many of the Canadian timberlands are subject to the constitutionally protected treaty or common-law rights of indigenous peoples of Canada. Most of British Columbia (B.C.) is not covered by treaties, and as a result the claims of B.C.’s indigenous peoples relating to forest resources have been largely unresolved. Nonetheless, the Supreme Court of Canada ruled that the Tsilhqot’in Nation holds indigenous title to approximately 1,900 square kilometers in B.C., the first time the court has declared title to exist based on historical occupation by indigenous peoples. Many indigenous groups continue to be engaged in treaty discussions with the governments of B.C., other provinces and Canada. Final or interim resolution of claims brought by indigenous groups can be expected to result in: •additional restrictions on the sale or harvest of timber, •potential increase in operating costs and •effect on timber supply and prices in Canada. We believe that such claims will not have a significant effect on our total harvest of timber or production of forest products in 2024, although they may have such an effect in the future. POLLUTION CONTROL REGULATIONS Our operations are subject to various federal, state, provincial and local pollution control laws and regulations. These laws and regulations, as well as market demands, impose controls with regard to: •air, water and land; •solid and hazardous waste management; •waste disposal; •remediation of contaminated sites and •the chemical content of some of our products. Compliance with these laws, regulations and demands usually involves capital expenditures as well as additional operating costs. We cannot easily quantify the future amounts of capital expenditures we might have to make to comply with these laws, regulations and demands or the effects on our operating costs because in some instances compliance standards have not been developed or have not become final or definitive. In addition, it is difficult to isolate the environmental component of most manufacturing capital projects. Our capital projects typically are designed to: •enhance safety; •extend the life of a facility; •lower costs and improve efficiency; •improve reliability; •increase capacity; •facilitate raw material changes and handling requirements; •increase the economic value of assets or products and •comply with regulatory standards. ENVIRONMENTAL CLEANUP We are involved in the environmental investigation or remediation of numerous sites, predominantly resulting from historical legacy operations. Of these sites: •we may have the sole obligation to remediate; •we may share that obligation with one or more parties; •several parties may have joint and several obligations to remediate and •we may have been named as a potentially responsible party for contaminated sites, including those designated as U.S. Superfund sites. Our liability with respect to these various sites could range from insignificant to substantial. The amount of liability depends on the: •quantity, toxicity and nature of materials at the site and •number and economic viability of the other responsible parties. We spent approximately $6 million in 2023 and expect to spend approximately $8 million in 2024 on environmental remediation of these sites. It is our policy to accrue for environmental remediation costs when we: •determine it is probable that such an obligation exists and •can reasonably estimate the amount of the obligation. Based on currently available information and analysis, we believe it is reasonably possible that our costs to remediate all the identified sites may exceed our current accruals of $75 million by up to $213 million. This estimate of the upper end of the range of reasonably possible additional costs is much less certain than the estimates we currently are using to determine how much to accrue. The estimate of the upper range also relies on assumptions less favorable to us among the range of reasonably possible outcomes. REGULATION OF AIR EMISSIONS IN THE U.S. The United States Environmental Protection Agency (EPA) has promulgated regulations for air emissions from: •wood products facilities and •industrial boilers. These regulations cover: •hazardous air pollutants that require use of maximum achievable control technology (MACT) and •controls and/or monitoring for pollutants that contribute to smog, haze and more recently, greenhouse gases (GHG). The EPA has issued several rules relating to MACT standards and GHG emissions from various energy-producing sources. Several court decisions have made the extent of applicability of these rules uncertain. Depending on the final outcomes of these decisions, these regulatory programs could affect our operations by increasing the cost of purchasing electricity or from mandated energy demand reductions that could apply to our mills and other facilities that we operate. The EPA is also expected to issue rules relating to biomass emissions, which is a significant source of energy at our mills. The effect of these WEYERHAEUSER COMPANY > 2023 ANNUAL REPORT AND FORM 10-K 23 existing and future emissions regulations, as well as related court decisions, on our operations remains uncertain. We continue to track and evaluate the litigation and regulatory developments but are not able to predict whether the regulations, when complete and implemented, will have a material effect on our operations. To address concerns about GHG as a pollutant, we closely monitor legislative, regulatory and scientific developments pertaining to climate change. For more information about the substantial progress we have made in reducing our GHG emissions, see our discussion in Carbon Record in the Environmental, Social and Governance (ESG) Practices — Environmental Stewardship section of this report. Additional factors that could affect regulation of GHG emissions in the future include: •policy proposals by federal or state governments regarding regulation of GHG emissions, •Congressional legislation regulating or taxing GHG emissions within the next several years and •establishment of a multistate or federal GHG emissions reduction trading system with potentially significant implications for all U.S. businesses. We believe these developments have not had, and in 2024 will not have, a significant effect on our operations. Although these measures could have a material adverse effect on our operations in the future, we expect that we will not be disproportionately affected by these measures as compared with owners of comparable operations. We maintain an active forestry research program to track and understand any potential effect from physical climate change related parameters that could affect the forests we own and manage and do not currently anticipate any near-term disruptions to our planned operations. REGULATION OF AIR EMISSIONS IN CANADA Our wood products facilities are regulated in Canada under provincial air quality rules. The Canadian federal government has also proposed an air quality management system (AQMS) as a comprehensive national approach for improving air quality in Canada to go along with existing provincial air quality regulations. The AQMS includes: •ambient air quality standards for outdoor air quality management across the country; •a framework for air zone air management within provinces and territories that targets specific sources of air emissions; •regional airsheds that facilitate coordinated action across borders; •improved intergovernmental collaboration to reduce emissions from the transportation sector. In addition to these existing and proposed regulations, Environment and Climate Change Canada, a Canadian federal agency, released the Pan-Canadian Framework on Clean Growth and Climate Change, a “Greenhouse Gas Emission Framework.” The framework put in place a national, sector- based GHG reduction program applicable to a number of industries, including ours. All Canadian provincial governments: •have GHG reporting requirements; •are working on reduction strategies and •together with the Canadian federal government, are considering new or revised emission standards. Along with clean air regulations, British Columbia, a province in which we operate, has adopted a carbon tax and Alberta, where we also have operations, has a mandatory GHG emission reduction regulation. Although these and related regulations and measures have not had, and we do not expect in 2024 that they will have, a material effect on our operations, they could in the future. REGULATION OF WATER IN THE U.S. Our operations are regulated under the Clean Water Act, which regulates the discharge of pollutants into the waters of the U.S. This generally means obtaining permits for certain of our silviculture activities and our operating facilities and abiding by applicable restrictions. Federal agency rulemaking and related litigation under the act affects the definition of water subject to the act’s regulation. This, in turn, has affected the number of required federal and state permits in some areas of our operations and led to adjustments of our operational practices, particularly relating to the application of pesticides and herbicides on timberlands, which has increased operating costs. State governments in the U.S. continue to promulgate total maximum daily load (TMDL) requirements for pollutants in water bodies that do not meet state or EPA water quality standards. State TMDL requirements may set: •limits on pollutants that may be discharged to a body of water; or •additional requirements, such as best management practices for nonpoint sources, including timberland operations, to reduce the amounts of pollutants. •industrial sector-based emission requirements that set a national base level of performance for major industries in Canada and In Canada, various levels of government have been working to address water issues including use, quality and management. Recent areas of focus include water allocation, regional 24 watershed protection, protection of drinking water, water pricing and a national water quality index. Pending and future federal and state rulemaking, and judicial challenges thereto, could make application of the Clean Water Act, as well as comparable state laws, more or less costly to Weyerhaeuser, and we are not able to predict the final resolution of these matters. Although this and related regulations have not had, and we do not expect in 2024 that they will have, a material effect on our operations, they could in the future. REGULATION OF WATER IN CANADA Changes to the Canadian Federal Fisheries Act have moved the focus of that legislation from habitat protection to fisheries protection and increased penalties. We expect further changes to these regulations, but we cannot predict the scope or potential effect, if any, on our operations. Although this and related Canadian regulations have not had, and we do not expect in 2024 that they will have, a material effect on our operations, they could in the future. WEYERHAEUSER COMPANY > 2023 ANNUAL REPORT AND FORM 10-K 25 FORWARD-LOOKING STATEMENTS This report contains statements concerning our future results and performance that are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995.

RISK FACTORS We are subject to various risks and events that could adversely affect our business, our financial condition, our results of operations, our cash flows and the price of our common stock. You should consider the following risk factors, in addition to the information presented elsewhere in this report, particularly in Our Business, Forward-Looking Statements and Management’s Discussion and Analysis of Financial Condition and Results of Operations (MD&A), as well as those set forth from time to time in our other public statements, reports, registration statements, prospectuses, information statements and other filings we make from time to time with the SEC, in evaluating us, our business and an investment in our securities. The risks discussed below are not the only risks we face, and our descriptions of such risks, here and elsewhere, should not be considered exhaustive. Additional risks not currently known to us or that we currently deem immaterial also may adversely affect our business, our financial condition, our results of operations, our cash flows and the price of our common stock. RISKS RELATED TO OUR BUSINESS AND INDUSTRY MARKET AND OTHER EXTERNAL RISKS The industries in which we operate are sensitive to macroeconomic conditions and consequently are highly cyclical. The overall levels of demand for the products we manufacture and distribute reflect fluctuations in levels of end-user demand, which consequently affect our sales and profitability. End-user demand depends in large part on general macroeconomic conditions, both in the U.S. and globally, as well as on local economic conditions. The length and magnitude of industry cycles vary over time, both by market and by product, but generally reflect changes in macroeconomic conditions and levels of industry capacity. Any decline or stagnation in macroeconomic conditions could cause us to experience lower sales volumes and reduced margins for our products. Low demand for new homes and home repair and remodeling can adversely affect our business, financial condition, results of operations and cash flows. Our business is particularly dependent upon the health of the U.S. housing market, and specifically on demand for new homes and home repair and remodeling. Demand in these markets is sensitive to changes in economic conditions such as the level of employment, consumer confidence, consumer income, the availability of financing and interest rate levels. Other factors that could limit or adversely affect demand for new homes and home repair and remodeling, and hence demand for our products, include factors such as changes in consumer preferences, limited wage growth, increases in non-mortgage consumer debt, any weakening in consumer confidence, as well as any increase in foreclosure rates and distress sales of houses. Catastrophic events may adversely affect the markets for our products and our business, financial condition, results of operations and cash flows. We are subject to the risk of various catastrophic events, including but not limited to the occurrence of: severe regional or local weather events or trends and related fires or flooding; wide-spread insect or pest infestations on one or more of our properties; significant geological events such as earthquakes, volcanic eruptions and major erosion in the form of landslides; significant geopolitical conditions or developments such as significant international trade disputes or domestic or foreign terrorist attacks, armed conflict and political unrest; and regional health epidemics or global health pandemics, such as the 2020 outbreak of the novel strain of coronavirus and its many subsequent mutations. Any one or more of these events or conditions, or other catastrophic events or developments, could significantly affect our ability to operate our businesses and adversely affect domestic and foreign general economic conditions and thus domestic or foreign market demand for our products. The impact of any one or more of these events or conditions may also trigger the occurrence of, or exacerbate, other risks discussed herein, any one of which could have a material adverse effect on our business, financial condition, results of operations and cash flows. WEYERHAEUSER COMPANY > 2023 ANNUAL REPORT AND FORM 10-K 27 Homebuyers’ ability to qualify for and obtain affordable mortgages could be affected by changes in interest rates, changes in home loan underwriting standards and government sponsored entities and private mortgage insurance companies supporting the mortgage market. by the federal government or by a state government to eliminate or substantially reduce these income tax deductions, or any significant increase in real property taxes by local governments, may increase the cost of homeownership and thus could adversely affect the demand for our products. Access to affordable mortgage financing is critical to the health of the U.S. housing market. Generally, increases in interest rates make it more difficult for home buyers to obtain mortgage financing, which could negatively affect demand for housing and, in turn, negatively affect demand for our wood products. After maintaining interest rates at historically low levels for an extended period of time, in the first quarter of 2022 the U.S. Federal Reserve began implementing a policy of incrementally raising rates. We cannot predict the extent to which the U.S. Federal Reserve’s current policy will be maintained or the timing, number, extent or direction of future rate adjustments. Along with prevailing interest rates, other significant factors affecting the demand for new homes relate to the ability of home buyers to obtain mortgage financing. During the last U.S. recession, credit requirements for home lending were severely tightened and the number of mortgage loans available for financing home purchases were thereby severely reduced. Although the availability of credit has improved since that time, the housing market could be limited or adversely affected if credit requirements were to again tighten or become more restrictive for any reason. Additionally, the liquidity provided to the mortgage industry by Fannie Mae and Freddie Mac, both of which purchase home mortgages and mortgage-backed securities originated by mortgage lenders, has been critical to the home lending market. Any political or other developments that would have the effect of limiting or restricting the availability of financing by these government sponsored entities could also adversely affect interest rates and the availability of mortgage financing. Whether resulting from further direct increases in borrowing rates, tightened underwriting standards on mortgage loans or reduced federal support of the mortgage lending industry, a challenging mortgage financing environment could reduce demand for housing and, therefore, adversely affect demand for our products. Changes in regulations relating to tax deductions for mortgage interest expense and real estate taxes could harm our future sales and earnings. Significant costs of homeownership include mortgage interest expense and real estate taxes, both of which are generally deductible for an individual’s federal and, in some cases, state income taxes. Federal legislation reduced the amount of mortgage interest and real estate taxes that certain taxpayers may deduct. These and any similar changes to income tax laws 28 PRODUCT PRICING AND PROFITABILITY Our profitability is affected by market dynamics outside of our control. Because commodity products have few distinguishing properties from producer to producer, competition for these products is based largely on price, which is determined by supply relative to demand and competition from substitute products. Prices for our products are also affected by many other factors outside of our control. As a result, we have little influence or control over the timing and extent of price changes, which often are volatile in our industry. Moreover, our profit margins with respect to these products depend, in part, on managing our costs, particularly raw material, labor (including contract labor) and energy costs, which represent significant cost components that also fluctuate based upon market and other factors beyond our control. Excess supply of logs and wood products may adversely affect prices and margins. Producers in our industry have in the past put downward pressure on product pricing by selling excess supply into the market. Our industry may increase harvest levels, which could lead to an oversupply of logs. Wood products producers may likewise expand manufacturing capacity, which could lead to an oversupply of manufactured wood products. Any such increases of industry supply to our markets could adversely affect our prices and margins. THIRD-PARTY SERVICE PROVIDERS We depend heavily on third parties for logging and transportation services, and any increase in the cost or any disruption in the availability of these services could materially adversely affect our business and operations and our financial results. Our businesses depend heavily on the availability of third-party service providers for the harvest of our timber and the transportation of our wood products and wood fiber. We are therefore considerably affected by the availability and cost of these services. Any significant increase in the operating costs to our service providers, including without limitation an increase in the cost of fuel, labor or insurance, could have a material negative effect on our financial results by increasing the cost of these services to us, as well as result in an overall reduction in the availability of these services altogether. Our third-party transportation providers are also subject to several events outside of their control, such as disruption of transportation infrastructure, labor issues including shortages of commercial truck drivers and natural disasters. Any failure of a third-party transportation provider to timely deliver our products, including delivery of our wood products and wood fiber to our customers and delivery of wood fiber to our mills, could harm our supply chain, negatively affect our customer relationships and have a material adverse effect on our financial condition, results of operations, cash flows and our reputation. As a result of weak business conditions in the timber industry that persisted for several years, there are fewer third-party service providers in certain markets to harvest and deliver our logs. This shortage has resulted in an overall increase in logging and hauling costs and, in some cases, compromised the general availability of these contractors. Any increase in harvest levels due to positive changes in macroeconomic conditions driving demand for logs could further strain the existing supply of third-party logging and hauling service providers. This, in turn, could increase the cost of log supply and delivery, or prevent us from fully capitalizing on favorable market conditions by limiting our ability to access and deliver our logs to market. MANAGING COMMERCIAL TIMBERLANDS RISKS Our ability to harvest and deliver timber may be subject to limitations which could adversely affect our financial condition, results of operations and cash flows. Our primary assets are our timberlands. Weather conditions, timber growth cycles, access limitations and availability of contract loggers and haulers may adversely affect our ability to harvest our timberlands. Other factors that may adversely affect our timber harvest include damage to our standing timber by fire or by insect or pest infestation, disease, prolonged drought, flooding, severe weather and other natural disasters. As discussed in more detail in the following risk factors, changes in global climate conditions could intensify the severity and rate of occurrence of any one or more of these risks that we currently face or introduce other risks that we currently cannot predict. Although damage from such causes usually is localized and affects only a limited percentage of standing timber, there can be no assurance that any damage affecting our timberlands will in fact be limited. As is common in the forest products industry, we do not maintain insurance coverage for damage to our timberlands. Our revenues, net income and cash flow from operations are dependent to a significant extent on the pricing of our products and our continued ability to harvest timber at adequate levels. Therefore, if we were to be restricted from harvesting on a significant portion of our timberlands for a prolonged period of time, or if material damage to a significant portion of our standing timber were to occur, we could suffer materially adverse effects to our financial condition, results of operations and cash flows. Future timber harvest levels may also be affected by our ability to timely and effectively replant harvested areas, which depends on several factors including changes in estimates of long-term sustainable yield because of silvicultural advances, natural disasters, fires, pests, insects and other hazards, regulatory constraints, availability of contractors, U.S. immigration policies and other factors beyond our control. Timber harvest activities are also subject to a number of federal, state and local regulations pertaining to the protection of fish, wildlife, water and other resources. Regulations, government agency policy and guidelines, and litigation, can restrict timber harvest activities and increase costs. Examples include federal and state laws protecting threatened, endangered and “at-risk” species, harvesting and forestry road building activities that may be restricted under the U.S. Federal Clean Water Act, state forestry practices laws, laws protecting aboriginal rights and other similar regulations. Our estimates of timber inventories and growth rates may be inaccurate and include risks inherent in calculating such estimates, which may impair our ability to realize expected revenues. Whether in connection with managing our existing timberland portfolio or assessing potential timberland acquisitions, we make and rely on important estimates of merchantable timber inventories. These include estimates of timber inventories that may be lawfully and economically harvested, timber growth rates and end-product yields. Timber growth rates and yield estimates are developed by forest biometricians and other experts using statistical measurements of tree samples on given property. These estimates are central to forecasting our anticipated timber harvests, revenues and expected cash flows. While the company has confidence in its timber inventory processes and the professionals in the field who administer them, future growth and yield estimates are inherently inexact and uncertain and subject to many external variables that could further affect their accuracy. These external variables include, among other things, disease, insect or pest infestation, natural disasters and changes in weather patterns, all of which could be exacerbated by the impacts of climate change. If these estimates are inaccurate, our ability to manage our timberlands in a sustainable or profitable manner may be compromised, which may cause our financial condition, results of operations, cash flows and our stock price to be adversely affected. WEYERHAEUSER COMPANY > 2023 ANNUAL REPORT AND FORM 10-K 29 Our financial condition, operating results and cash flows will be materially affected by supply and demand for timber. A variety of factors affect prices for timber, including available supply, changes in economic conditions that affect demand, the level of domestic new construction and remodeling activity, interest rates, credit availability, population growth, weather conditions, insect or pest infestation and other factors. These factors vary by region, by timber type (i.e., sawlogs or pulpwood logs) and by species. Timber prices are affected by changes in demand on a local, national and international level. The closure of a mill in a region where we own timber could have a material adverse effect on demand in that region, and therefore pricing. For example, as the demand for paper continues to decline, closures of pulp mills in some of our operating regions have adversely affected the regional demand for pulpwood and wood chips. Additionally, some of our Asian log export markets, particularly China, have a history of significant volatility. Lower demand for our export logs could have a negative effect on timber prices, particularly in the western region. Timber prices are also affected by changes in timber supply and availability at the local, national and international level. Our timberland ownership is concentrated in Alabama, Arkansas, Georgia, Louisiana, Maine, Mississippi, North Carolina, Oklahoma, Oregon and Washington. In some of these states, much of the timberland is privately owned. Increases in timber prices often result in substantial increases in harvesting on private timberlands, including lands owned by others and not previously made available for commercial timber operations, causing a short-term increase in supply that moderates such price increases. In western states such as Oregon and Washington, where a greater proportion of timberland is government-owned, any substantial increase in timber harvesting from government-owned land could significantly reduce timber prices. On a local level, timber supplies can fluctuate depending on factors such as changes in weather conditions and harvest strategies of local timberland owners, as well as occasionally high timber salvage efforts due to events such as insect or pest infestations, fires or other natural disasters. Demand for timber in foreign markets can fluctuate due to a variety of factors as well, including but not limited to: changes in the fundamental economic conditions that affect demand for logs in a given export market country or region; any substantial increase in supply of logs from local or regional sources, including such sources that periodically supply large amounts of salvage timber as a result of disease or infestation, and other factors. Timberlands make up a significant portion of our business portfolio and we are therefore subject to real estate investment risks. Our real property holdings are primarily timberlands and we may make additional timberlands acquisitions in the future. As the owner and manager of approximately 10.5 million acres of timberlands, we are subject to the risks that are inherent in concentrated real estate investments. A downturn in the real estate industry generally, or the timber or forest products industries specifically, could reduce the value of our properties and adversely affect our financial condition, results of operations and cash flows. Such a downturn could also adversely affect our customers and reduce the demand for our products, as well as our ability to execute upon our strategy of selling nonstrategic timberlands and timberland properties that have higher and better uses at attractive prices. These risks may be more pronounced than if we diversified our investments outside of real property holdings. MANUFACTURING AND SELLING WOOD PRODUCTS RISKS A material disruption at one of our manufacturing facilities could prevent us from meeting customer demand, reduce our sales, and negatively affect our results of operations, financial condition and cash flows. Any of our manufacturing facilities, or any of our equipment within an otherwise operational facility, could cease operations unexpectedly due to a number of events, including: •unscheduled maintenance outages; •prolonged power failures; •equipment failure; •chemical spill or release; •explosion of a boiler; •fires, floods, windstorms, earthquakes, hurricanes or other severe weather conditions or catastrophes affecting the production of goods or the supply of raw materials (including fiber); •the effect of drought or reduced rainfall on water supply; •labor difficulties; •disruptions in transportation or transportation infrastructure, including roads, bridges, rail, tunnels, shipping and port facilities; •terrorism or threats of terrorism; •cyberattack; •governmental regulations; •other operational problems and •effects of viral or disease outbreaks and any resulting epidemic or global pandemic. 30 We cannot predict the duration of any such downtime or extent of facility damage. If one of our facilities or machines were to incur significant downtime, our ability to meet our production targets and satisfy customer demand could be impaired, resulting in lower sales and income. Additionally, we may be required to make significant unplanned capital expenditures. Although some risks are not insurable and some coverage is limited, we purchase insurance on our manufacturing facilities for damage from fires, floods, windstorms, earthquakes, other severe weather conditions, equipment failures and boiler explosions. Such insurance may not be sufficient to recover all of our damages. Some of our wood products are vulnerable to declines in demand due to competing technologies or materials. Our products compete with non-fiber based alternatives or with alternative products in certain market segments. For example, plastic, wood/plastic or composite materials may be used by builders as alternatives to our wood products such as lumber, veneer, plywood and oriented strand board. Changes in prices for oil, chemicals and wood-based fiber can change the competitive position of our products relative to available alternatives and could increase substitution of those products for our products. If use of these or other alternative products grows, demand for and pricing of our products could be adversely affected. Our financial condition, results of operations and cash flows could be materially adversely affected by changes in product mix or pricing. Our results may be materially adversely affected by a change in our product mix or pricing. Some of our wood products, such as lumber, veneer, plywood and oriented strand board, are commodities and are subject to fluctuations in market pricing. If pricing on our commodity products decreases and if we are not successful in increasing sales of higher-priced, higher-value products, or if we are not successful in implementing price increases, or there are delays in acceptance of price increases or higher-priced products, our financial condition, results of operations and cash flows could be materially and adversely affected. Price discounting, if required to maintain our competitive position in one or more markets, could result in lower than anticipated price realizations and margins. We face intense competition in our markets; any failure to compete effectively could have a material adverse effect on our business, financial condition, results of operations and cash flows. We compete with North American producers and, for some of our product lines, global producers, some of which may have greater financial resources and lower production costs than we do. The principal basis for competition for many of our products is selling price. Our industries also are particularly sensitive to other factors including innovation, design, quality and service, with varying emphasis on these factors depending on the product line. To the extent that any of our competitors are more successful with respect to any key competitive factor, our ability to attract and retain customers and maintain and increase sales could be materially adversely affected. Any failure to compete effectively could have a material adverse effect on our business, financial condition, results of operations and cash flows. Competition from lumber imports could vary significantly and have a material effect on U.S. timber and lumber prices. The future amount and pricing of lumber imports entering U.S. markets remain uncertain. Historically, Canada has been the most significant source of lumber for the U.S. market, particularly in the new home construction market. We produce lumber in our Canadian mills, but the bulk of our lumber production is in the U.S. There have been many disputes and subsequent trade agreements regarding sales of softwood lumber between Canada and the U.S. The last agreement, which required Canadian softwood lumber facilities, including our mills, to pay an export tax when the price of lumber is at or below a threshold price, expired in October 2015. Since that time, the U.S. Department of Commerce has issued countervailing and antidumping duties on softwood lumber imports from Canada based on findings of injury to U.S. lumber producers. We are not able to predict when, or if, a new softwood lumber agreement with Canada will be reached or, if reached, what the terms of the agreement would be. Similarly, we are not able to predict if the current U.S. policy of imposing import duties on Canadian softwood lumber will continue. We could, therefore, experience significant downward pressure on timber and lumber prices caused by Canadian lumber imports. We also periodically face competition from lumber producers in Europe. Historically, European imports to U.S. markets have been more robust during strong domestic lumber market cycles, which can limit the benefits we realize from high timber and lumber prices by creating downward pressure on pricing. As with Canadian imports, we cannot predict the timing nor the extent of future levels of European lumber imports and could therefore experience significant downward pressure on timber and lumber prices stemming from this source of competition. Customer demand for certain brands of sustainably-produced products could reduce competition among buyers for our products or cause other adverse effects. We have adopted the Sustainable Forestry Initiative®(SFI)® standard for wood fiber supplied to our manufacturing facilities, both from our timberlands and from third-party suppliers. If WEYERHAEUSER COMPANY > 2023 ANNUAL REPORT AND FORM 10-K 31 customer preference for a sustainability standard other than SFI increases, or if the SFI standard falls into disfavor, there may be reduced demand and lower prices for our products relative to competitors who can supply products sourced from forests certified to competing certification standards. If we seek to comply with such other standards, we could incur materially increased costs for our operations or be required to modify our operations, such as reducing harvest levels. FSC, in particular, employs standards that are geographically variable and could cause a material reduction in the harvest levels of some of our timberlands, most notably in the Pacific Northwest. Our business and operations could be materially adversely affected by changes in the cost or availability of raw materials and energy. We rely heavily on certain raw materials (principally wood fiber and chemicals) and energy sources (principally natural gas, electricity and fuel oil) in our manufacturing processes. Our ability to increase earnings has been, and will continue to be, affected by changes in the costs and availability of such raw materials and energy sources. We may not be able to fully offset the effects of higher raw material or energy costs through price increases, productivity improvements, cost-reduction programs or hedging arrangements. The U.S. has experienced significant inflation, which could continue or worsen and therefore negatively affect the cost or availability of raw materials and energy, which we may not be able to fully pass onto our customers. PHYSICAL RISKS RELATED TO CLIMATE CHANGE Changes in global or regional climate conditions could significantly harm our timberland assets and have a negative impact on our results of operations, cash flow and financial condition. Climate change has the potential to cause significant disruptions to our business and results of operations, cash flow and financial condition. There is increasing concern that increases in global average temperatures caused by increased concentrations of carbon dioxide and other greenhouse gases in the atmosphere could cause significant changes in weather patterns, including changes to precipitation patterns and growing seasons. These changes could, in the long term and in some locations, lead to slower growth of our trees and, potentially, changes to the species mix that we manage in our timber assets. An increase in global temperature could also lead to an increase in the frequency and severity of extreme weather events and other natural disasters. Thus, damage or access to our timberland assets by existing causes, such as fire, insect or pest infestation, disease, prolonged drought, flooding, windstorms and other natural disasters, could be significantly worsened by climate change. Extreme weather and temperatures could also lead to interruptions of normal work conditions in our operations. Any one or more of these negative effects on commercial timberland operations from climate change, both our own and that of other commercial timberland operators, could also have a material adverse impact on our Wood Products business by significantly affecting the availability, cost and quality of the wood fiber used in our mill operations. WORKFORCE RISK Our business is dependent upon attracting, retaining and developing key personnel. Our success depends, to a significant extent, upon our ability to attract, retain and develop employees to help run our business, including but not limited to employees needed to staff our operations and key personnel capable of performing at a high level to fill roles in senior corporate and operations management. Our financial condition, results of operations or cash flows could be significantly adversely affected if we were to fail to recruit, retain, and develop such employees, or if there were to occur any significant decrease in the availability of such employees or any significant increase in the cost of providing such employees with competitive total compensation and benefits. For the last few years, we have experienced a competitive and challenging labor market. In addition, most of our operations are located in rural communities where we draw from local labor forces to fill many positions in both our Timberlands and Wood Products operations. These communities are often beset with many challenges ranging from struggling economies to limited community resources and access to educational opportunities, any one or more of which could lead to decreases in location populations and therefore decreases in the availability of an able and qualified workforce. A sustained labor shortage or increased turnover rates within our employee base, whether caused by any singular event such as the global pandemic or as a result of general macroeconomic or other factors, could disrupt our operations and lead to increased labor costs, such as an increased need for overtime work by current employees to meet demand and increased wage rates to attract and retain employees. A strike or other work stoppage, or our inability to renew collective bargaining agreements on favorable terms, could adversely affect our financial results. A significant number of employees in our Western Timberlands and Wood Products businesses are covered by collective bargaining agreements. As we previously disclosed, certain of these employees commenced a work stoppage in 2022, which was shortly thereafter resolved, affecting the company’s 32 operations in Washington and Oregon. If our unionized workers were to engage in a protracted work stoppage, we could experience a significant disruption of operations at our facilities. Likewise, if our non-unionized operations were to become unionized and thereafter commence a work stoppage, we could experience a significant disruption of operations at our facilities. If we are unable to reach or renew collective bargaining agreements with our unionized workers, we could also experience higher ongoing labor costs. Any work stoppage by any one or more of our significant customers, transportation providers or suppliers could also have similar negative effects on us. Depending on scope and duration, any of these labor disruptions could have a material adverse effect on our financial condition, results of operations or cash flows. PENSION PLAN LIABILITY RISK Volatility in interest rates and lower than expected returns on our pension assets could reduce the funded status of our defined benefit pension plans, requiring us to make significant additional cash contributions to our benefit plans. A portion of our current and former employees have accrued benefits under our defined benefit pension plans. Although the plans are not open to newly hired or rehired employees, current employees hired before the plan closure continue to accrue benefits. Requirements for funding our pension plan liabilities are based on a number of actuarial assumptions, including the expected rate of return on our plan assets and the discount rate applied to our pension plan obligations. Fluctuations in equity market returns and changes in long-term interest rates could increase our costs under our defined benefit pension plans and may significantly affect future contribution requirements. It is unknown what the actual investment return on our pension assets will be in future years and what interest rates may be at any given point in time. We cannot therefore provide any assurance of what our actual pension plan costs will be in the future, or whether we will be required under applicable law to make future material plan contributions. See Note 8: Pension and Other Post-Employment Benefit Plans for additional information about these plans, including funding status. STRATEGIC INITIATIVES AND EXECUTION RISK Our business and financial results may be adversely affected if we are unable to successfully execute on important strategic initiatives. Our strategic initiatives are designed to improve our results of operations and drive long-term shareholder value. These initiatives include, among others, optimizing cash flow through operational excellence, reducing costs to achieve industry- leading cost structure, innovating in higher-margin products and pursuing opportunities in emerging markets through our Real Estate, Energy & Natural Resources segment. For example, through our natural climate solutions business we are pursuing opportunities to participate in new and emerging markets for forest carbon credits and carbon storage, and the success of these endeavors is subject to many known and unknown risks. Known risks include, but are not limited to, market acceptance of our products and services, changes to demand for our products and services as these new markets evolve over time and political and regulatory developments that may make it more costly, or impossible, to pursue these business opportunities. There can be no assurance that we will be able to successfully implement any one or more of our important strategic initiatives in accordance with our expectations, which could result in an adverse effect on our business and financial results. We may be unsuccessful in carrying out our acquisition strategy. We intend to strategically pursue acquisitions and strategic divestitures when market conditions warrant. As with any investment, our acquisitions may not perform in accordance with our expectations. In addition, we anticipate financing many of these acquisitions through cash from operations, borrowings under our unsecured credit facilities, proceeds from equity or debt offerings or proceeds from strategic asset dispositions, or any combination thereof. Our inability to finance future acquisitions on favorable terms, or at all, could adversely affect our ability to successfully execute strategic acquisitions and thereby adversely affect our results of operations, financial condition and cash flows. FOREIGN CURRENCY RISK We will be affected by changes in currency exchange rates. We have manufacturing operations in Canada. We are also an exporter and compete with global producers of products very similar to ours. Therefore, we are affected by changes in the strength of the U.S. dollar, particularly relative to the Canadian dollar, euro, yuan and yen, and the strength of the euro relative to the yen. Changes in exchange rates could materially and adversely affect our sales volumes, margins and results of operations. WEYERHAEUSER COMPANY > 2023 ANNUAL REPORT AND FORM 10-K 33 LEGAL, REGULATORY AND TAX RISKS ENVIRONMENTAL LAWS AND REGULATIONS We could incur substantial costs as a result of compliance with, violations of, or liabilities under applicable environmental laws and other laws and regulations. We are subject to a wide range of general and industry-specific laws and regulations relating to the protection of the environment and wildlife, including those governing: •air emissions, •wastewater discharges, •harvesting, •silvicultural activities, including use of pesticides and herbicides, •forestry operations and endangered species habitat protection, •surface water management, •the storage, usage, management and disposal of hazardous substances and wastes, •the cleanup of contaminated sites, •landfill operation and closure obligations, •building codes and •health and safety matters. We have incurred, and we expect to continue to incur, significant capital, operating and other expenditures complying with applicable environmental laws and regulations and as a result of remedial obligations, and there can be no assurances that existing accruals for specific matters will be adequate to cover future costs. We also could incur substantial costs, such as civil or criminal fines, sanctions and enforcement actions (including orders limiting our operations or requiring corrective measures, installation of pollution control equipment or other remedial actions), cleanup and closure costs, and third-party claims for property damage and personal injury as a result of violations of, or liabilities under, environmental laws and regulations. As the owner and operator of real estate, we may be liable under environmental laws for cleanup, closure and other damages resulting from the presence and release of hazardous substances on or from our current or former properties or operations. In addition, surface water management regulations may present liabilities and are subject to change. The amount and timing of environmental expenditures is difficult to predict, and in some cases, our liability may exceed forecasted amounts or the value of the property itself. The discovery of additional contamination or the imposition of additional cleanup obligations at our sites or third-party sites may result in significant additional costs. 34 We also lease some of our properties to third-party operators for the purpose of exploring, extracting, developing and producing oil, gas, rock and other minerals in exchange for fees and royalty payments. These activities are also subject to federal, state and local laws and regulations. These operations may create risk of environmental liabilities for any unlawful discharge of oil, gas or other chemicals into the air, soil or water. Generally, these third-party operators indemnify us against any such liability, and we require that they maintain liability insurance during the term of our lease with them. However, if for any reason our third-party operators are not able to honor their indemnity obligation, or if the required liability insurance were not in effect, then it is possible that we could be deemed responsible for costs associated with environmental liability caused by such third-party operators. Any material liability we incur as a result of activities conducted on our properties by us or by others with whom we have a business relationship could adversely affect our financial condition. We also anticipate public policy developments at the state, federal and international level regarding climate change and energy access, security and competitiveness. As discussed below, we expect these developments to address emission of carbon dioxide, renewable energy and fuel standards, and the monetization of carbon. These developments may also include mandated changes to energy use and building codes which could affect homebuilding practices. Enactment of new environmental laws or regulations or changes in existing laws or regulations, or the interpretation of these laws or regulations, might require significant expenditures. We also anticipate public policy developments at the state, federal and international level regarding taxes and a number of other areas that could require significant expenditures. LEGAL AND REGULATORY RISKS RELATED TO CLIMATE CHANGE Governmental response to climate change at the international, federal and state levels may affect our financial condition, results of operations, cash flows and profitability. There continue to be numerous international, U.S. federal and state-level initiatives and proposals to address domestic and global climate issues. Within the U.S. and Canada, some of these proposals would regulate and/or tax the production of carbon dioxide and other greenhouse gases to facilitate the reduction of carbon compound emissions into the atmosphere and provide tax and other incentives to produce and use cleaner energy. Indeed, such regulations have already been passed into law in some Canadian provinces and in Washington state, where we have mill operations. Climate change effects, if they occur, and governmental initiatives, laws and regulations to address potential climate concerns, could increase our costs and have a long-term adverse effect on our businesses and results of operations. Future legislation or regulatory activity in this area remains uncertain, and its effect on our operations is unclear at this time. take a charge and make cash payments for all or a portion of any related awards of damages. Any one or more of such charges or cash payment could materially and adversely affect our financial condition, results of operations or cash flows for the quarter or year in which we record or pay it. However, climate change legislation or related government mandates, standards or regulations intended to mitigate or reduce carbon compound, greenhouse gas emissions or other climate change effects could have significant adverse effects on our business and operations as well as our ability to achieve our recently announced business goals in emerging carbon credit and carbon storage markets. Any one or more of such new legal requirements and regulations could, for example, significantly increase the costs for our mills to comply with stricter air emissions regulations. They could also limit harvest levels for commercial timberland operators, which could in turn adversely affect our timberland operations as well as potentially lead to significant increases in the cost of energy, wood fiber and other raw materials for our wood products businesses. Any one or more of these developments, as well as other unforeseeable governmental responses to climate change, could have a material adverse effect on our financial condition, results of operations, cash flows and profitability. LEGAL MATTERS We are involved in various environmental, regulatory, product liability and other legal matters, disputes and proceedings that, if determined or concluded in a manner adverse to our interests, could have a material adverse effect on our financial condition. We are, from time to time, involved in a number of legal matters, disputes and proceedings (legal matters), some of which involve ongoing litigation. These include, without limitation, legal matters involving environmental clean-up and remediation, warranty and non-warranty product liability claims, regulatory issues, contractual and personal injury claims and other legal matters. In some cases, all or a portion of any loss we experience in connection with any such legal matters will be covered by insurance; in other cases, any such losses will not be covered. The outcome, costs and other effects of current legal matters in which we are involved, and any related insurance recoveries, cannot be determined with certainty. Although the disclosures in Note 13: Legal Proceedings, Commitments and Contingencies contain management’s current views of the effect such legal matters could have on our financial results, there can be no assurance that the outcome of such legal matters will be as currently expected. It is possible that there could be adverse judgments against us in some or all major litigation matters against us, and that we could be required to REIT STATUS AND TAX IMPLICATIONS If we fail to remain qualified as a REIT, our taxable income would be subject to tax at corporate rates and we would not be able to deduct dividends to shareholders. In any taxable year in which we fail to qualify as a REIT, unless we are entitled to relief under the IRC: •We would not be allowed to deduct dividends to shareholders in computing our taxable income. •We would be subject to federal and state income tax on our taxable income at applicable corporate rates. •We also would be disqualified from treatment as a REIT for the four taxable years following the year during which we lost qualification. Qualification as a REIT involves the application of highly technical and complex provisions of the IRC to our operations and the determination of various factual matters and circumstances not entirely within our control. There are only limited judicial or administrative interpretations of these provisions. We closely monitor our compliance with all of the various requirements for maintaining our REIT status. For example, we regularly test our compliance with the general requirement that at least 75 percent of the market value of our total assets consist of REIT-qualifying interests in real property (such as timberlands) and certain other specified qualifying assets, and that no more than 25 percent of the market value of our total assets may consist of assets that are not REIT- qualifying assets. Although we operate in a manner consistent with these REIT qualification rules, we cannot provide assurance that we are or will remain qualified. Certain of our business activities are subject to corporate- level income tax and potentially subject to prohibited transactions tax. Under the IRC, REITs generally must engage in the ownership and management of income producing real estate. For the company, this generally includes owning and managing a timberland portfolio for the production and sale of standing timber. Certain activities that generate non-qualifying REIT income could constitute “prohibited transactions.” Prohibited transactions are defined by the Internal Revenue Code generally to be sales or other dispositions of property to customers in the ordinary course of a trade or business. Accordingly, the harvesting and sale of logs, the development or sale of certain WEYERHAEUSER COMPANY > 2023 ANNUAL REPORT AND FORM 10-K 35 We may be limited in our ability to fund distributions using cash generated through our TRSs. The ability of the company to receive dividends from our TRSs is limited by the rules with which we must comply to maintain our status as a REIT. In particular, at least 75 percent of gross income for each taxable year as a REIT must be derived from real estate sources including sales of our standing timber and other types of qualifying real estate income, and no more than 25 percent of our gross income may consist of dividends from our TRSs and other non-real estate income. This limitation on our ability to receive dividends from our TRSs may affect our ability to fund cash distributions to our shareholders using cash flows from our TRSs. The net income of our TRSs is not required to be distributed, and income of our TRSs that is not distributed to the company will not be subject to the REIT income distribution requirement. To maintain our qualification as a REIT and to avoid an excise tax, we are generally required to distribute substantially all of our taxable income to our shareholders. Generally, REITs are required to distribute 90 percent of their ordinary taxable income and (to avoid an excise tax) 95 percent of their net capital gains income. Capital gains may be retained by the REIT but would be subject to corporate income taxes. If capital gains were retained rather than distributed, our shareholders would be deemed to have received a taxable distribution (about which we would notify them), with a credit or refund for any federal income tax paid by the company. We believe that we are not required to distribute material amounts of cash since substantially all of our taxable income is treated as capital gains income. As previously discussed in these Risk Factors, our board of directors, in its sole discretion, determines the amount, timing and frequency of our dividends to shareholders. Changes in tax laws or their interpretation could adversely affect our shareholders and our results of operations. Federal and state tax laws are constantly under review by persons involved in the legislative process, the IRS, the United States Department of the Treasury and state taxing authorities. Changes to tax laws could adversely affect our shareholders or increase our effective tax rates. We cannot predict with certainty whether, when, in what forms, or with what effective dates, the tax laws applicable to us or our shareholders may be changed. timberlands and other real estate, and the manufacture and sale of wood products are conducted through one or more of our wholly-owned TRSs, the net income of which is subject to corporate-level tax. By conducting our business in this manner, we believe that we satisfy the REIT requirements of the Internal Revenue Code. However, if the Internal Revenue Service (IRS) were to successfully assert that these or any of our activities conducted at the REIT constituted prohibited transactions, we could be subject to the 100 percent tax on the net income from such activities. The extent of our use of our TRSs may affect our REIT qualification and affect the price of our common shares relative to the share price of other REITs. We conduct a significant portion of our business activities through one or more TRSs. The use of our TRSs enables us to engage in non-REIT qualifying business activities such as the harvesting and sale of logs, manufacture and sale of wood products, and the development and sale of certain higher and better use (HBU) property. Our TRSs are subject to corporate- level income tax. Under the Code, no more than 20 percent of the value of the gross assets of a REIT may be represented by securities of one or more TRSs. This limitation may affect our ability to increase the size of our TRSs’ operations. While we intend to monitor the value of our investments in the stock and securities of our TRSs to ensure compliance with the 20 percent limitation, we cannot provide assurance that we will always be able to comply with the limitation so as to maintain REIT status. If we were to exceed the 20 percent limitation, we may be forced to sell or otherwise distribute assets of our TRSs in order to remain a qualified REIT. Furthermore, our use of TRSs may cause the market to value our common shares differently than the shares of other REITs, which may not use TRSs at all, or as extensively as we use them. The failure of our subsidiary REIT to maintain its separate REIT qualification could affect the company’s own REIT qualification. A significant amount of our timberlands is held in a subsidiary that we operate to qualify as a REIT, and we may in the future invest in other timberlands and other real estate through one or more other subsidiary entities that are intended to qualify as REITs. While our ownership interest in the subsidiary REIT is a qualifying real estate asset for purposes of the company’s 75 percent asset test described above, any failure of the subsidiary REIT to maintain its own separate REIT status would generally result in the subsidiary being subject to regular U.S. corporate income tax, as described above, and the company’s ownership interest in the subsidiary no longer qualifying as a real estate asset for purposes of the 75 percent asset test. If this were to occur, the company’s own REIT qualification could be affected. 36 IMPORT/EXPORT TAXES AND DUTIES We may be required to pay significant taxes or tariffs on our exported products or countervailing and anti-dumping duties or tariffs on our imported products. We export logs and finished wood products to foreign markets, and our ability to do so profitably is affected by U.S. and foreign trade policy. International trade disputes occur frequently and can be taken to an international trade court or tribunal for resolution of unfair trade practices between countries. U.S. international trade policy could result in one or more of our foreign export market jurisdictions adopting trade policy making it more difficult or costly for us to export our products to those countries, including, for example, placing export or phytosanitary restrictions on our products. We could therefore experience reduced revenues and margins in any of our businesses that is adversely affected by international trade tariffs, duties, taxes, customs or dispute settlement terms. To the extent such trade policies increase prices, they could also reduce the demand for our products and could have a material adverse effect on our business, financial results and financial condition, including facility closures or impairments of assets. We cannot predict future trade policy or the terms of any settlements of international trade disputes and their effect on our business. OTHER RISKS RISKS RELATED TO OWNING OUR STOCK Our cash dividends are not guaranteed and may fluctuate. Our board of directors, in its sole discretion, determines the amount and timing of our cash dividends to shareholders based on consideration of a number of factors. These factors include, but are not limited to: our results of operations and cash flows; current and forecasted economic conditions; changes in the current or expected prices and demand for our products and the general market demand for timberlands, including those timberland properties that have higher and better uses; current and forecasted harvest levels; balancing various capital allocation priorities and considerations including without limitation the company’s capital requirements and debt repayment obligations; various finance considerations, including the company’s credit ratings, borrowing capacity, debt covenant restrictions that may impose limitations on cash payments and other related factors and tax considerations. Consequently, the amount, timing and frequency of our dividends, including our quarterly base dividend and annual supplemental dividend, may fluctuate. The market price of our common stock may be influenced by many factors, some of which are beyond our control. The market price of our common stock may be influenced by many factors, some of which are beyond our control, including without limitation those described above and elsewhere in this report, as well as the following: •actual or anticipated fluctuations in our operating results or our competitors’ operating results; •announcements by us or our competitors of new products, capacity changes, significant contracts, acquisitions or strategic investments or initiatives; •our growth rate and our competitors’ growth rates; •general economic conditions; •conditions in the financial markets; •market interest rates and the relative yields on other financial instruments; •general perceptions and expectations regarding housing markets, interest rates, commodity prices and currencies; •changes in stock market analyst recommendations regarding us, our competitors or the forest products industry generally, or lack of analyst coverage of our common stock; •sales of our common stock by our executive officers, directors and significant shareholders; •sales or repurchases of substantial amounts of common stock; •fluctuation in the market price of our products (see Product Pricing and Profitability above); •changes in accounting principles and •changes in tax laws and regulations. In addition, there has been significant volatility in the market price and trading volume of securities of companies, including companies operating in the forest products industry, that often has been unrelated to individual company operating performance. Some companies that have experienced volatile market prices for their securities have had securities litigation brought against them. If litigation of this type is brought against us, it could result in substantial costs and divert management’s attention and resources. CAPITAL MARKETS RISKS Deterioration in economic conditions and capital markets could adversely affect our access to capital. Challenging market conditions could impair the company’s ability to raise debt or equity capital or otherwise access capital markets on terms acceptable to us, which may, among other effects, reduce our ability to refinance debt maturities or take advantage of growth and expansion opportunities. Moreover, our businesses require substantial capital for repair or replacement of existing facilities or equipment. While we believe our capital resources will be adequate to meet our WEYERHAEUSER COMPANY > 2023 ANNUAL REPORT AND FORM 10-K 37 current projected operating needs, capital expenditures and other cash requirements, if for any reason we are unable to access capital for our operating needs, capital expenditures and other cash requirements on acceptable economic terms, or at all, we could experience a material adverse effect on our business, financial condition, results of operations and cash flows. Changes in credit ratings issued by nationally recognized rating organizations could adversely affect our cost of financing and have an adverse effect on the market price of our securities. Credit rating agencies rate our debt securities on factors that include our operating results and balance sheet, actions that we take, their view of the general outlook for our industry and their view of the general outlook for the economy. Ratings decisions by these agencies include maintaining, upgrading or downgrading our current rating, as well as placing the company on a “watch list” for possible future ratings actions. Any downgrade of our credit rating, or decision by a rating agency to place us on a “watch list” for possible future downgrading could have an adverse effect on our ability to access credit markets, increase our cost of financing, and have an adverse effect on the market price of our securities. INFORMATION SYSTEMS AND CYBERSECURITY Risks associated with the use of Information Technology (IT) systems, including from security breaches, new system implementations and integrations or other significant disruptions, could affect our ability to operate our businesses effectively, adversely affect our reported financial results, affect our reputation and expose us to potential liability or litigation. We use IT systems to carry out our operational activities, maintain our business records, and collect and store sensitive data, including but not limited to intellectual property and personally identifiable information. Some of our systems are internally managed and some are maintained by third-party service providers. Although we employ, and we believe our third- party service providers employ, what we deem to be reasonably adequate security measures and controls, there can be no assurance that our security measures will be effective against the risks we face from cyber-attacks, including from: computer hackers, foreign governments and cyber terrorists; malicious code (such as malware, viruses and ransomware); an intentional or unintentional personnel action; a natural disaster; a hardware or software corruption, failure or error; a telecommunications system failure; a service provider failure or error; or any one or more other causes of a security breach, failure or disruption. The increased prevalence and sophistication of Artificial Intelligence (AI) tools, such as AI-enabled malware, could increase the risks of cyber-attacks to our systems and to those of our third-party service providers. Implementation of new IT systems, including replacement of legacy systems with new or upgraded versions, could also pose a significant risk to our business, as any such implementation can involve system failure, potential loss or corruption of our important data, security or internal control failures, delays, cost overruns and operational disruption. Although we have, on occasion, experienced cybersecurity threats to our data and information systems, including phishing attacks, to date no events of this nature have had a material adverse effect on our business or otherwise caused material harm to the company. However, if in the future our IT systems are significantly disrupted, shut down or otherwise compromised for any reason, or if our data is destroyed, misappropriated or inappropriately disclosed, our financial results or our business operations, or both, could be negatively affected. Additionally, we could suffer significant losses or incur significant liabilities, including without limitation damage to our reputation, loss of customer confidence or goodwill and significant expenditures of time and money to address and remediate resulting damages to affected individuals or business partners or to defend ourselves in resulting litigation or other legal proceedings by affected individuals, business partners or regulators. For more information about our cybersecurity program, see Item 1C Cybersecurity. 38 UNRESOLVED STAFF COMMENTS There are no unresolved comments that were received from the SEC staff relating to our periodic or current reports under the Securities Exchange Act of 1934. CYBERSECURITY RISK MANAGEMENT Our risk management program includes focused efforts on identifying, assessing and managing cybersecurity risk, including the following: •A robust information security training program that requires all company employees with access to our networks to participate in regular and mandatory training on how to be aware of, and help defend against, cyber risks, combined with periodic testing to measure the efficacy of our training efforts. •Alignment of our program with the National Institute of Standards and Technology Cybersecurity Framework to prevent, detect and respond to cyberattacks. •Ongoing adoption of a “zero trust” cybersecurity model. •Regular and robust testing of our systems to assess our vulnerability to cyber risk, which includes targeted penetration testing, tabletop incident response exercises, periodic audits of our systems by outside industry experts and regular vulnerability scanning. •A formal vendor risk assessment process to ensure any vendors with information access have appropriate security measures and practices in place. •Engaging external cybersecurity experts in incident response development and management. •Business continuity plans and critical recovery backup systems. •Insurance for damage to property caused by a cyberattack. Our chief information security officer (CISO) is primarily responsible for leading the technical team that assesses and manages cybersecurity risk for the company on a day-to-day basis. He and other members of the cybersecurity team have deep and broad experience and training in cybersecurity management, as well as relevant education and industry recognized certifications in information systems security. CYBERSECURITY INCIDENT RESPONSE PROCESS We maintain and actively update a cybersecurity incident response plan that outlines the steps we take to identify, investigate and take action in response to any potentially material cyber incidents. Our response plan ensures that our Cyber Incident Response Team, which includes our CISO, members of our senior management team and select members of our legal staff, is timely informed of and consulted with respect to any potentially material cyber incidents. BOARD OVERSIGHT OF CYBER RISK Members of management, including our CISO, regularly report on the company’s cybersecurity matters to both our board’s Audit Committee and to the full board, which has primary oversight responsibility in this area, as follows: •Our cybersecurity program and risks are specifically discussed at least three times per year (including as part of our discussions regarding enterprise risk management). •Our internal audit function’s reviews of our information security programs and controls are included in quarterly reports to the Audit Committee. •Current information security issues that arise during the year are discussed throughout the year if potentially significant to the company and are discussed with our chairman and Audit Committee chair between board meetings as appropriate. WEYERHAEUSER COMPANY > 2023 ANNUAL REPORT AND FORM 10-K 39 RISK MITIGATION We also manage cybersecurity risk by limiting our threat landscape. For example, we do not store, transmit or process many of the types of data commonly targeted in cyberattacks, such as consumer credit card or financial information, nor do we store or maintain significant proprietary data on our systems. Moreover, our businesses do not involve or represent national infrastructure, the likes of which are common targets of cyber attackers (e.g., energy, oil & gas, transportation, communications, banking and financial systems, etc.). We recognize that cyber threats are a permanent part of the risk landscape and that new threats are constantly evolving. For these and other reasons, cybersecurity is a top risk management priority at Weyerhaeuser. Like many companies, we face a number of cybersecurity risks in the day-to-day operation of our business. Although to date these risks have not materialized into any instances or series of instances that have had a material adverse effect on our business or otherwise caused material harm to the company, we have, on occasion, experienced cybersecurity threats to our data and information systems, including phishing attacks. For more information about the cybersecurity risks we face, see the risk factor entitled “Information Systems and Cybersecurity” in Item 1A Risk Factors.

LEGAL PROCEEDINGS Refer to Note 13: Legal Proceedings, Commitments and Contingencies. SEC regulations require us to disclose certain information about proceedings arising under federal, state or local environmental provisions if we reasonably believe that such proceedings may result in monetary sanctions above a stated threshold. In accordance with these regulations, the company uses a threshold of $1 million for purposes of determining whether disclosure of any such proceedings is required pursuant to this item.

ECONOMIC AND MARKET CONDITIONS AFFECTING OUR OPERATIONS Our market conditions and the strength of the broader U.S. economy are, and will continue to be, influenced by the trajectory of activity in the U.S. housing and repair and remodel segments, inflation trends and interest rates. The demand for sawlogs within our Timberlands segment is directly affected by domestic production of wood-based building products. The strength of the U.S. housing market, particularly new residential construction, strongly affects demand in our Wood Products segment, as does repair and remodeling activity. Seasonal weather patterns impact the level of construction activity in the U.S., which in turn affects demand for our logs and wood products. Our Timberlands segment, specifically the Western region, is also affected by export demand and trade policy. Japanese housing starts are a key driver of export log demand in Japan. The demand for pulpwood from our Timberlands segment is directly affected by the production of pulp, paper and oriented strand board (OSB) as well as the demand for biofuels, such as wood-burning pellets made from pulpwood. Our Timberlands segment is also influenced by the availability of harvestable timber. In general, Western log markets are highly tensioned by available supply, while Southern log markets have more available supply. However, additional mill capacity being added in the U.S. South has led to tightening of markets in certain geographies. Our Real Estate, Energy and Natural Resources segment is affected by a variety of factors, 42 including the general state of the economy, local real estate market conditions, the level of construction activity in the U.S. and evolution of emerging renewable energy and carbon-related markets. Over the past year, particularly in the first half of 2023, home sales and building activity slowed due in part to higher mortgage interest rates, reduced affordability and general macroeconomic conditions. In the latter part of 2023, new home sales and construction activity strengthened, supported by near record-low levels of existing inventory. On a seasonally adjusted annual basis, as reported by the U.S. Census Bureau, housing starts for fourth quarter 2023 averaged 1.5 million units, a 6.1 percent increase from third quarter 2023. Single- family starts averaged 1.0 million units in fourth quarter 2023, a 7.7 percent increase from third quarter 2023. Multi-family starts averaged 412 thousand units in fourth quarter 2023, which was a 2.2 percent increase from third quarter 2023. Single-family construction is the primary driver for our business as compared to multi-family due to the amount of wood products used. Sales of newly built, single-family homes averaged a seasonally adjusted annual rate of 652 thousand units for fourth quarter 2023, a decrease of 6.0 percent from third quarter 2023. Over the medium to long-term, we expect a favorable U.S. housing construction market supported by strong demographics in the key homebuying age cohorts, a decade of underbuilding and a historically low housing inventory. Repair and remodeling expenditures were steady from third quarter 2023 to fourth quarter 2023 according to the Census Bureau Advance Retail Spending report. Do-it-yourself activity has been returning to more normalized levels while professionally contracted activities have benefited from larger projects and increases in home equity levels. Over the longer term, we expect this sector to return to pre-pandemic growth trends with healthy household balance sheets, elevated home equity and an aging U.S. housing stock, with a median age of 43 years. In U.S. wood product markets, demand for lumber and OSB was influenced by cautious buyer sentiment at the outset of fourth quarter 2023. As the quarter progressed, demand increased in response to strong single-family housing starts and improving macroeconomic conditions. The Random Lengths Framing Lumber Composite price averaged $384/MBF and the OSB Composite averaged $406/MSF in fourth quarter 2023. Over the course of the fourth quarter, composite prices for lumber decreased from $422/MBF to $395/MBF and composite prices for OSB decreased from $454/MSF to $430/MSF. In Western log markets, Douglas fir sawlog prices decreased 2.8 percent in fourth quarter 2023 compared with third quarter 2023, as reported by Fastmarkets RISI Log Lines based on Weyerhaeuser’s sales mix. Overall, domestic log demand and prices faced downward pressure at the outset of the quarter, as mills adjusted to a softening lumber market and worked through elevated log inventories. As the quarter progressed, lumber markets improved, and log supply decreased seasonally. In the South, delivered sawlog prices decreased 0.5 percent in fourth quarter 2023 compared to third quarter 2023 and declined 3.6 percent from fourth quarter 2022 as reported by TimberMart-South. This was primarily driven by ample log supply, elevated mill inventories and reduced demand for finished goods during the quarter. Currency exchange rates, available supply from other countries and trade policy affect our export businesses. During fourth quarter 2023, end use demand in export markets was mixed. In Japan, total housing starts decreased 4.7 percent year to date through November compared to the same period in 2022, while the key Post and Beam segment saw a 6.2 percent decrease. Lumber imports to Japan from Europe were more balanced than in previous quarters, providing support for logs. China’s weaker end use demand for logs and lumber was offset by lower competitive supply, leading to stable pricing for logs from the West. Interest rates affect our business primarily through their impact on mortgage rates and housing affordability, their general impact on the economy and their influence on our capital management activities. Actions by the U.S. Federal Reserve, the overall condition of the economy and fluctuations in financial markets are all factors that influence long-term interest rates. 30-year mortgage rates, which are correlated with long-term interest rates, decreased from 7.3 percent at the end of third quarter 2023 to 6.6 percent at the end of fourth quarter 2023, according to economic data from Freddie Mac. Many builders have been able to offset higher mortgage rates through discounts, mortgage rate buydowns and modifying product offerings such as home sizes and finishes. Higher rates have also locked-in many existing homeowners from selling, reducing inventories of existing homes for sale which has led to increased demand for available new homes. Increased inflation affects the cost of our operations across each of our business segments, including costs for raw materials, transportation, energy and labor. The Consumer Price Index increased at an annual rate of 3.4 percent as of December 2023, which is markedly down from its peak of over 9.0 percent annual increase in June 2022. While we can offset some of the impacts of inflation through our sales activities, our operational excellence initiatives and our procurement practices, not all of the costs associated with inflation can be fully mitigated or passed on to the consumer. The condition of the labor market affects all of our businesses as it relates to our ability to attract and retain employees and contractors. The unemployment rate of 3.7 percent in December 2023 remained near historically low levels and decreased 0.1 percent from the end of third quarter 2023. Governments and businesses across the globe are taking action on climate change and are making significant commitments towards decarbonizing operations and reducing greenhouse gas emissions to net zero. Achieving these commitments will require governments and companies to take major steps to modify operations, invest in low-carbon activities and purchase credits to reduce environmental impacts. We believe we are uniquely positioned to help entities achieve these commitments through natural climate solutions, including forest carbon sequestration, carbon capture and storage and renewable energy activities.

Costs of Sales Costs of sales decreased $572 million — 9 percent — primarily due to decreased sales volumes across most product lines and decreased raw material prices within our Wood Products segment, as well as decreased third-party log purchases within our Timberlands segment. Operating Income Operating income decreased $1,894 million — 61 percent — primarily due to a $1,938 million decrease in consolidated gross margin (see discussion of components above), partially offset by an $84 million gain on sale of timberlands (refer to Note 4: Timberland Acquisitions and Divestitures). Net earnings decreased $1,041 million — 55 percent — primarily due to the $1,894 million decrease in operating income discussed above. This decrease was partially offset by: •a $327 million decrease in income tax expense (refer to Income Taxes); •a $276 million decrease in debt extinguishment charges (refer to Note 11: Long-Term Debt, Net); •a $209 million decrease in non-operating pension and other post-employment benefit costs (refer to Note 8: Pension and Other Post-Employment Benefit Plans) and •a $51 million increase in interest income and other attributable to interest earned on short-term investments held for a portion of the year in 2023 and an increase in the interest rate on our cash and investment accounts.

WEYERHAEUSER COMPANY > 2023 ANNUAL REPORT AND FORM 10-K 45 COMPARING 2023 WITH 2022 Net Sales — Unaffiliated Customers Net sales to unaffiliated customers decreased $204 million — 11 percent — primarily due to a $210 million decrease in Western log sales primarily attributable to a 20 percent decrease in sales realizations, partially offset by a $10 million increase in stumpage and pay-as-cut timber sales. Intersegment Sales The volume of real estate sales is a function of many factors, including the general state of the economy, demand in local real estate markets, the ability of buyers to obtain financing, the number of competing properties listed for sale, the seasonal nature of sales, the plans of adjacent landowners, our expectations of future price appreciation, the timing of harvesting activities and the availability of government and not-for-profit funding. In any period, the average price per acre sold will vary based on the location and physical characteristics of parcels sold. Intersegment sales increased $11 million — 2 percent — primarily due to a 9 percent increase in sales volumes, partially offset by a 6 percent decrease in sales realizations. COMPARING 2023 WITH 2022 Net Sales Net sales decreased $5 million — 1 percent — primarily attributable to lower prices in our Energy and Natural Resources business, partially offset by an increase in acres sold. Costs of Sales Costs of sales increased $13 million — 12 percent — primarily attributable to an increase in acres sold. Operating Income and Net Contribution to Earnings Operating income and net contribution to earnings decreased $7 million — 3 percent — primarily attributable to the change in the components of gross margin, as discussed above, partially offset by a $10 million noncash impairment charge related to the planned divestiture of legacy coal assets in 2022 with no similar activity in 2023. WOOD PRODUCTS HOW WE DID We report sales volumes and annual production data for our Wood Products segment in Our Business/What We Do/Wood Products. Costs of Sales Costs of sales decreased $50 million — 3 percent — primarily due to decreased Western third-party log purchases, partially offset by increased logging and hauling costs and increased sales volumes. Operating Income and Net Contribution to Earnings Operating income and net contribution to earnings decreased $40 million — 8 percent — primarily due to the change in the components of gross margin, as discussed above, partially offset by an $84 million gain on sale of timberlands recorded in fourth quarter 2023. REAL ESTATE, ENERGY AND NATURAL RESOURCES HOW WE DID We report acres sold and average price per acre for our Real Estate, Energy and Natural Resources segment in Our Business/What We Do/Real Estate, Energy and Natural Resources.

COMPARING 2023 WITH 2022 Net Sales Costs of sales decreased $467 million — 9 percent — primarily due to decreased sales volumes across most product lines, as well as decreased raw material prices. Operating Income and Net Contribution to Earnings Operating income and net contribution to earnings decreased $1,827 million — 72 percent — primarily due to the change in the components of gross margin, as discussed above. UNALLOCATED ITEMS Unallocated items are gains or charges not related to, or allocated to, an individual operating segment. They include all or a portion of items such as: •share-based compensation, •pension and post-employment costs, •elimination of intersegment profit in inventory and LIFO—the last-in, first-out method, •foreign exchange transaction gains and losses resulting from changes in exchange rates primarily related to our U.S. dollar denominated cash and debt balances that are held by our Canadian subsidiary, as well as •interest income and other. Net sales decreased $2,301 million — 29 percent — primarily due to: Net Charge to Earnings for Unallocated Items DOLLAR AMOUNTS IN MILLIONS •a $1,251 million decrease in structural lumber sales attributable to a 37 percent decrease in sales realizations; •a $634 million decrease in oriented strand board sales attributable to a 40 percent decrease in sales realizations; •a $136 million decrease in complementary building products attributable to decreased sales volumes across most products; •a $126 million decrease in engineered I-joists sales attributable to a 13 percent decrease in sales realizations, as well as a 10 percent decrease in sales volumes; •a $79 million decrease in engineered solid section sales attributable to a 6 percent decrease in sales realizations, as well as a 3 percent decrease in sales volumes; •a $37 million decrease in medium density fiberboard sales attributable to a 24 percent decrease in sales volumes, partially offset by a 6 percent increase in sales realizations; •a $27 million decrease in softwood plywood sales attributable to a 28 percent decrease in sales realizations, partially offset by a 20 percent increase in sales volumes and •an $11 million decrease in other products produced attributable to decreased sales volumes for veneer and plywood byproducts.

INTEREST EXPENSE Our net interest expense incurred for the last two years was: •$280 million in 2023 and •$270 million in 2022. LIQUIDITY AND CAPITAL RESOURCES We are committed to maintaining an appropriate capital structure that provides financial flexibility and enables us to protect the interests of our shareholders and meet our obligations to our lenders, while also maintaining access to all major financial markets. As of December 31, 2023, we had $1.2 billion in cash and cash equivalents and $1.5 billion of availability on our line of credit, which expires in March 2028. We believe we have sufficient liquidity to meet our cash requirements for the foreseeable future. Interest expense increased by $10 million compared to 2022 primarily due to the May 2023 issuance of debt securities that increased our weighted average outstanding debt. CASH FROM OPERATIONS Consolidated net cash from operations was: Refer to Note 11: Long-Term Debt, Net for further information. INCOME TAXES •$1,433 million in 2023 and •$2,832 million in 2022. COMPARING 2023 WITH 2022 As a REIT, we generally are not subject to federal corporate level income taxes on REIT taxable income that is distributed to shareholders. Historical distributions to shareholders, including amounts and tax characteristics, are summarized in the table below. Net cash from operations decreased by $1,399 million, primarily due to decreased cash inflows from our business operations. This change was partially offset by a $503 million decrease in our cash paid for income taxes. AMOUNTS PER SHARE Common — capital gain distribution Common — ordinary dividend (qualified) Common — return of capital 2023 2022 $ 1.66 $ 1.59 $ $ — $ 0.07 — $ 0.51 Pension Contributions and Benefit Payments Made and Expected During 2023, we contributed a total of $20 million to our pension and post-employment benefit plans, compared to a total of $24 million during 2022. We are required to pay corporate income taxes on earnings of our TRSs, which include our Wood Products segment and portions of our Timberlands and Real Estate & ENR segments’ earnings. Our provision for income taxes is primarily driven by earnings generated by our TRSs. Our provision for income taxes the last two years was: •$98 million in 2023 and •$425 million in 2022. Income tax expense decreased by $327 million compared to 2022 primarily due to decreases in our pretax earnings and effective income tax rate. During 2022, we recorded a $69 million tax benefit in connection with our early debt retirement and a $53 million tax benefit related to our noncash pension settlement charge. Refer to Note 19: Income Taxes, Note 11: Long-Term Debt, Net and Note 8: Pension and Other Post-Employment Benefit Plans for further information. For 2024, we expect to contribute approximately $20 million to our pension and post-employment benefit plans. Refer to Note 8: Pension and Other Post-Employment Benefit Plans for further information. INVESTING IN OUR BUSINESS Cash from investing activities includes items such as: •capital expenditures for property, equipment and reforestation, •acquisitions of timberlands, •proceeds from sales of assets and operations and •purchases and maturities of short-term investments. Consolidated net cash from investing activities was: •$(508) million in 2023 and •$(759) million in 2022. 48 COMPARING 2023 WITH 2022 LONG-TERM DEBT Net cash from investing activities increased by $251 million, primarily due to: •a $166 million increase in proceeds from the sale of timberlands; •a $62 million decrease in cash spent on the acquisition of timberlands and •a $25 million decrease in capital expenditures for property and equipment. Summary of Capital Spending by Business Segment DOLLAR AMOUNTS IN MILLIONS Timberlands Wood Products Unallocated Items Total 2023 2022 $ 111 $ 113 323 13 347 8 $ 447 $ 468 We expect our capital expenditures for 2024 to be approximately $440 million. The amount we spend on capital expenditures could change due to: •future economic conditions, •environmental regulations, •changes in the composition of our business, •weather, •timing of equipment purchases and •capital needs related to other business opportunities. Our consolidated long-term debt (including current portion) was: •$5,069 million as of December 31, 2023 and •$5,053 million as of December 31, 2022. The increase in our long-term debt during 2023 is primarily attributable to the May 2023 issuance of $750 million of 4.750 percent notes and the December 2023 issuance of a $250 million senior unsecured term loan, offset by the December 2023 repayment of our $860 million 5.207 percent note and the July 2023 repayment of our $118 million 7.125 percent notes. The weighted average interest rate and the weighted average maturity on our long-term debt as of December 31, 2023 were 5.35 percent and 7.6 years, respectively. See Note 11: Long-Term Debt, Net for more information. LINE OF CREDIT In March 2023, we entered into a new $1.5 billion five-year senior unsecured revolving credit facility, which expires in March 2028 and replaced the existing facility which was set to expire in January 2025. Borrowings will bear interest at a floating rate based on either the adjusted term Secured Overnight Financing Rate (SOFR) plus a spread or a mutually agreed upon base rate plus a spread. As of December 31, 2023 and December 31, 2022, we had no outstanding borrowings on the revolving credit facility and we were in compliance with the revolving credit facility covenants. FINANCING Our Covenants Cash from financing activities includes items such as: •issuances and payments of debt, •borrowings and payments on our revolving line of credit and •payments for cash dividends and repurchasing stock. Consolidated net cash from financing activities was: •$(1,342) million in 2023 and •$(2,491) million in 2022. COMPARING 2023 WITH 2022 Net cash from financing activities increased by $1,149 million in 2023, primarily due to: •a $412 million decrease in cash used for repurchases of common stock; •a $401 million decrease in cash paid for dividends and •a $336 million decrease in net cash used for payments on long-term debt. Our key covenants include the requirement to maintain: •a minimum total adjusted shareholders’ equity of $3.0 billion and •a defined debt-to-total-capital ratio of 65 percent or less. Our total adjusted shareholders’ equity is comprised of: •total shareholders’ equity, •excluding accumulated other comprehensive income (loss), •minus our investment in our unrestricted subsidiaries. Our capitalization is comprised of: •total debt, •plus total adjusted shareholders’ equity. As of December 31, 2023, we had: •total adjusted shareholders’ equity of $10.5 billion and •a defined debt-to-total-capital ratio of 32.5 percent. When calculating compliance in accordance with financial debt covenants as of December 31, 2023 and December 31, 2022, WEYERHAEUSER COMPANY > 2023 ANNUAL REPORT AND FORM 10-K 49 we excluded the full amount of accumulated other comprehensive loss of $293 million and $247 million, respectively. See Note 14: Shareholders’ Interest for further information on accumulated other comprehensive loss. There are no other significant financial debt covenants related to our third-party debt. CREDIT RATINGS As of December 31, 2023, our long-term issuer credit rating was BBB and Baa2 from S&P and Moody’s, respectively. DIVIDENDS We paid cash dividends on common shares of: •$1,216 million in 2023 and •$1,617 million in 2022. The decrease in dividends paid is primarily due to a supplemental dividend of $0.90 per share based on 2022 financial results for a total of $660 million paid in first quarter 2023 in comparison to a supplemental dividend of $1.45 per share based on 2021 financial results for a total of $1,084 million paid in first quarter 2022. On January 25, 2024, our board of directors declared a supplemental dividend of $0.14 per share based on 2023 financial results. The dividend is payable on February 27, 2024 to shareholders of record as of the close of business on February 16, 2024. We plan to supplement our base dividend each year with an additional return of cash, in the form of a supplemental cash dividend and/or share repurchase, to achieve our targeted annual payout of total cash to shareholders of 75 to 80 percent of Adjusted Funds Available for Distribution (Adjusted FAD). For further information on Adjusted FAD see Performance and Liquidity Measures. SHARE REPURCHASES We repurchased 4.1 million common shares for approximately $125 million (including transaction fees) during the year ended December 31, 2023. We repurchased 16.0 million common shares for approximately $550 million (including transaction fees) in 2022. As of December 31, 2023, we had remaining authorization of $252 million for future share repurchases. For further information on share repurchases see Note 14: Shareholders’ Interest. OUR CONTRACTUAL OBLIGATIONS AND COMMERCIAL COMMITMENTS More details about our contractual obligations and commercial commitments are in Note 8: Pension and Other Post- Employment Benefit Plans, Note 10: Line of Credit, Note 11: Long-Term Debt, Net, Note 13: Legal Proceedings, Commitments and Contingencies, Note 16: Leases and Note 19: Income Taxes. Significant Contractual Obligations as of December 31, 2023 Significant contractual obligations as of December 31, 2023 include our long-term debt obligations and lease obligations. Refer to Note 11: Long-Term Debt, Net and Note 16: Leases, respectively, for further information. Additional significant contractual obligations are included below. DOLLAR AMOUNTS IN MILLIONS PAYMENTS DUE BY PERIOD LESS THAN 1 YEAR TOTAL 1–3 YEARS 3–5 YEARS MORE THAN 5 YEARS Interest(1) $ 1,982 $ 276 $ 498 $ 379 $ 829 Purchase obligations(2) Employee-related obligations(3) $ $ 550 $ 186 $ 238 $ 91 $ 35 277 $ 117 $ 23 $ 18 $ 37 (1) Amounts presented for interest payments assume that all long-term debt obligations outstanding as of December 31, 2023 will remain outstanding until maturity. (2) Purchase obligations include agreements to purchase goods or services that are enforceable and legally binding on the company and that specify all significant terms, including: fixed or minimum quantities to be purchased; fixed, minimum or variable price provisions and the approximate timing of the transaction. Purchase obligations exclude arrangements that the company can cancel without penalty. (3) The timing of certain payments within this category will be triggered by retirements or other events. These payments can include workers compensation, deferred compensation and banked vacation, among other obligations. When the timing of payment is uncertain, the amounts are included in the total column only. Minimum pension funding is required by established funding standards and estimates are not made for 2025 onward. Estimated payments of contractually obligated post-employment benefits are not included due to the uncertainty of payment timing. OFF-BALANCE SHEET ARRANGEMENTS Off-balance sheet arrangements have not had — and are not reasonably likely to have — a material effect on our current or future financial condition, results of operations or cash flows. Note 10: Line of Credit contains our disclosures of surety bonds and letters of credit. ENVIRONMENTAL MATTERS, LEGAL PROCEEDINGS AND OTHER CONTINGENCIES See Note 13: Legal Proceedings, Commitments and Contingencies. 50 ACCOUNTING MATTERS CRITICAL ACCOUNTING ESTIMATES In the preparation of our financial statements we follow established accounting policies and make estimates that affect both the amounts and timing of the recording of assets, liabilities, revenues and expenses. We base our judgments and estimates on historical experience and assumptions we believe are appropriate and reasonable under current circumstances. Actual results, however, could differ materially from the estimated amounts we have recorded. Some of these estimates require judgments about matters that are inherently uncertain. Accounting policies whose application involve a significant level of estimation uncertainty and may have a material effect on our results of operations or financial condition are considered critical accounting estimates. DISCOUNT RATES FOR PENSION AND POST-EMPLOYMENT BENEFIT PLANS Discount rates are used to estimate the net present value of our pension and other post-employment plan obligations. These rates are determined at the measurement date by matching current spot rates of high-quality corporate bonds with maturities similar to the timing of expected cash outflows for benefits. The selection of discount rates requires judgment as well as the involvement of actuarial specialists. These specialists assist with selecting yield curves based on published indices for high-quality corporate bonds and projecting the timing and amount of cash flows associated with our obligations to ultimately support our determination of an appropriate discount rate for each plan. Our discount rates as of December 31, 2023 are: •5.2 percent for our U.S. pension plans — compared with 5.4 percent at December 31, 2022; •5.1 percent for our U.S. post-employment benefit plans — compared with 5.4 percent at December 31, 2022; •4.7 percent for our Canadian pension plans — compared with 5.3 percent at December 31, 2022 and •4.6 percent for our Canadian post-employment benefit plans — compared with 5.3 percent at December 31, 2022. Pension expenses for 2024 will be based on the 5.2 percent and 4.7 percent assumed discount rates for the U.S. pension plans and the Canadian pension plans, respectively, and the 5.1 percent and 4.6 percent assumed discount rates for the U.S. and Canadian post-employment benefit plans, respectively. Our discount rates are important in determining the cost of our plans. A 50 basis point decrease in our discount rate would increase expense or reduce a credit by approximately: •$11 million for our U.S. qualified pension plans and •$2 million for our Canadian registered pension plans. Details about our other significant accounting policies are in Note 1: Summary of Significant Accounting Policies. PROSPECTIVE ACCOUNTING PRONOUNCEMENTS A summary of prospective accounting pronouncements is in Note 1: Summary of Significant Accounting Policies. PERFORMANCE AND LIQUIDITY MEASURES We use Adjusted EBITDA as a key performance measure to evaluate the performance of the consolidated company and our business segments. This measure should not be considered in isolation from, and is not intended to represent an alternative to, our results reported in accordance with U.S. generally accepted accounting principles (U.S. GAAP). However, we believe Adjusted EBITDA provides meaningful supplemental information for our investors about our operating performance, better facilitates period to period comparisons and is widely used by analysts, lenders, rating agencies and other interested parties. Our definition of Adjusted EBITDA may be different from similarly titled measures reported by other companies. Adjusted EBITDA, as we define it, is operating income adjusted for depreciation, depletion, amortization, basis of real estate sold and special items.

In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2023, in conformity with U.S. generally accepted accounting principles. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 16, 2024 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting. Basis for Opinion These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion. Critical Audit Matter The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates. Projected benefit obligations for pensions As discussed in Notes 1 and 8 to the consolidated financial statements, the Company’s projected benefit obligations for pension plans were $2,347 million as of December 31, 2023, which included the projected benefit obligation for the U.S. qualified pension plans. The Company estimates the liability related to their pension plans using actuarial models that include assumptions about the Company’s discount rates. WEYERHAEUSER COMPANY > 2023 ANNUAL REPORT AND FORM 10-K 55 We identified the evaluation of the Company’s projected benefit obligation for the U.S. qualified pension plans as a critical audit matter. This is due to the sensitivity of the obligation to changes in the discount rate used and the subjectivity in evaluating the rate. Additionally, the assessment of the discount rate required specialized actuarial skills and knowledge. The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls related to the U.S. qualified pension obligation process. This included controls related to the actuarial determination of the discount rate used in the valuation of the projected benefit obligation for the U.S. qualified pension plans. These procedures also included analyzing year-over- year changes to the projected cash flows associated with the obligation. Additionally, we involved actuarial professionals with specialized skills and knowledge, who assisted in the evaluation of the Company’s discount rate by: •evaluating the selected yield curve used to determine the discount rate •assessing changes in the discount rate from the prior year against changes in published indices •evaluating the discount rate based on the projected cash flows compared with those of similar plans. /s/ KPMG LLP We have served as the Company’s auditor since 2002.

accounting policies describe: •our election to be taxed as a real estate investment trust, •how we report our results, •changes in how we report our results and •how we account for certain key items. OUR ELECTION TO BE TAXED AS A REAL ESTATE INVESTMENT TRUST (REIT) Our 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 expect to derive most of our REIT income from investments in timberlands, including the sale of standing timber through pay-as-cut sales contracts and lump sum timber deeds. We continue to be required to pay federal corporate income taxes on earnings of our Taxable REIT Subsidiaries (TRSs), which include our Wood Products segment and portions of our Timberlands and Real Estate, Energy and Natural Resources (Real Estate & ENR) segments. HOW WE REPORT OUR RESULTS Our report includes: •consolidated financial statements, •our business segments, •estimates, •fair value measurements and •foreign currency translation. Consolidated Financial Statements Our consolidated financial statements provide an overall view of our results and financial condition. They include our accounts and the accounts of entities that we control, including: •majority-owned domestic and foreign subsidiaries and •variable interest entities in which we are the primary beneficiary. They do not include our intercompany transactions and accounts, which are eliminated. Throughout these Notes to Consolidated Financial Statements, unless specified otherwise, references to “Weyerhaeuser,” “the company,” “we” and “our” refer to the consolidated company. Reportable business segments are determined based on the company’s “management approach,” as defined by Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 280, Segment Reporting. The management approach is based on the way the chief operating decision maker organizes the segments within a company for making decisions about resources to be allocated and assessing their performance. We are principally engaged in: •growing and harvesting timber; •maximizing the value of our acreage through the sale of higher and better use (HBU) properties and monetizing the value of surface and subsurface assets through leases and royalties and •manufacturing, distributing and selling products made from trees. Our business segments are organized based primarily on products and services. SEGMENT Timberlands Real Estate & ENR Wood Products PRODUCTS AND SERVICES Logs, timber, recreational leases and other products. Real Estate (sales of timberlands) and ENR (rights to explore for and extract hard minerals, construction materials, natural gas production, wind and solar). Structural lumber, oriented strand board, engineered wood products and building materials distribution. We also transfer raw materials, semi-finished materials and end products among our business segments. Because of this intracompany activity, accounting for our business segments involves pricing products transferred between our business segments at current market values. Unallocated items are gains or charges not related to, or allocated to, an individual operating segment. They include all or a portion of items such as share-based compensation, pension and post-employment costs, elimination of intersegment profit in inventory and LIFO, foreign exchange transaction gains and losses, interest income and other. Estimates We prepare our financial statements according to U.S. generally accepted accounting principles (U.S. GAAP). This requires us to make estimates and assumptions during our reporting periods and at the date of our financial statements. The estimates and assumptions affect our: •reported amounts of assets, liabilities and equity; •disclosure of contingent assets and liabilities and •reported amounts of revenues and expenses. WEYERHAEUSER COMPANY > 2023 ANNUAL REPORT AND FORM 10-K 63 While we believe the assumptions used in preparing these estimates are appropriate and reasonable, actual results can and do differ from those estimates and assumptions. balances comparable from year to year. Our reclassifications had no effect on consolidated net earnings or equity. Fair Value Measurements We use a fair value hierarchy in accounting for certain nonfinancial assets and liabilities including: •long-lived assets (asset groups) measured at fair value for an impairment assessment; •pension plan assets measured at fair value and •asset retirement obligations initially measured at fair value. The fair value hierarchy is based on inputs to valuation techniques that are used to measure fair value that are either observable or unobservable. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources, while unobservable inputs reflect a reporting entity’s pricing based upon its own market assumptions. The fair value hierarchy consists of the following three levels: •Level 1: Inputs are unadjusted quoted prices for identical assets or liabilities traded in an active market. •Level 2: Inputs are quoted prices in non-active markets for which pricing inputs are observable either directly or indirectly at the reporting date. •Level 3: Inputs are derived from valuation techniques in which one or more significant inputs or value drivers are unobservable. Foreign Currency Translation HOW WE ACCOUNT FOR CERTAIN KEY ITEMS This section provides information about how we account for certain key items related to: •capital investments, •financing our business and •our operations. ITEMS RELATED TO CAPITAL INVESTMENTS Key items related to accounting for capital investments pertain to property and equipment, timber and timberlands and impairment of long-lived assets. Property and Equipment We maintain property accounts on an individual asset basis and account for them as follows: •Improvements to and replacements of major units of property are capitalized. •Maintenance, repairs and minor replacements are expensed. •Depreciation is calculated using a straight-line method at rates based on estimated service lives. •Costs associated with logging roads that we intend to utilize for a period longer than one year are capitalized. These roads are then amortized over an estimated service life. •Cost and accumulated depreciation of property sold or retired are removed from the accounts and the gain or loss is included in earnings. We translate foreign currencies into U.S. dollars in two ways: Timber and Timberlands •assets and liabilities — at the exchange rates in effect as of our balance sheet date and •revenues and expenses — at average monthly exchange rates throughout the year. CHANGES IN HOW WE REPORT OUR RESULTS Changes in how we report our results come from: •reclassification of certain balances and results from prior years to make them consistent with our current reporting and •accounting changes made upon our adoption of new accounting guidance. We carry timber and timberlands at cost less depletion. Depletion refers to the carrying value of timber that is harvested or sold. Key activities affecting how we account for timber and timberlands include: •reforestation, •depletion and •forest management in Canada. Reforestation. Generally, we capitalize initial site preparation and planting costs as reforestation and then expense costs after the first planting as they are incurred or over the period of expected benefit. These expensed costs include: Reclassifications We have reclassified certain balances and results from prior years to be consistent with our 2023 reporting. This makes •fertilization, •vegetation and insect control, •pruning and precommercial thinning and •property taxes. 64 Accounting practices for these costs do not change when timber becomes merchantable and harvesting starts. Timber Depletion. To determine depletion rates, we divide the net carrying value of timber by the related volume of timber estimated to be available over the growth cycle. To determine the growth cycle volume of timber, we consider: •regulatory and environmental constraints, •our management strategies, •inventory data improvements, •growth rate revisions and recalibrations and •known dispositions and inoperable acres. In addition, the duration of the harvest cycle varies by geographic region and species of timber. Depletion rate calculations do not include estimates for: •future silviculture or sustainable forest management costs associated with existing stands; •future reforestation costs associated with a stand’s final harvest and recovered from the estimated undiscounted future cash flows of the asset and greater than fair market value (the amount we could receive if we were to sell the asset). Impaired assets held for use are written down to fair value, while impaired assets held for sale are written down to fair value less cost to sell. We determine fair value based on: •appraisals, •market pricing of comparable assets, •discounted value of estimated future cash flows from the asset, •replacement values of comparable assets and •agreed upon sale price or offer price. Key assumptions used in developing estimates of fair value would include the estimated future cash flows used to assess recoverability, discount rates and probability of alternative outcomes. ITEMS RELATED TO FINANCING OUR BUSINESS •future volume in connection with the replanting of a stand subsequent to its final harvest. Key items related to financing our business include financial instruments, cash equivalents and concentration of risk. We include the cost of timber harvested in the carrying values of raw materials and product inventories. As these inventories are sold to third parties, we include them in costs of sales. Forest Management in Canada. We manage timberlands under long-term licenses in various Canadian provinces that are: •granted by the provincial governments; •granted for initial periods of 15 to 25 years and •renewable provided we meet reforestation, operating and management guidelines. Calculation of the fees we pay on the timber we harvest: •varies from province to province, •is tied to product market pricing and •depends upon the allocation of land management responsibilities in the license. Impairment of Long-Lived Assets We review the carrying value of long-lived assets whenever an event or a change in circumstance indicates that the carrying value of the asset or asset group may not be recoverable through future operations. The carrying value is the original cost, less accumulated depreciation and any past impairments recorded. If we evaluate recoverability, we are required to estimate future cash flows and residual values of the asset or asset group. Key assumptions used in developing estimates of future cash flows and residual values could include probability of alternative outcomes, product pricing, raw material cost and product sales. An impairment occurs when the carrying value of a long-lived asset is greater than the amount that could be Financial Instruments We estimate the fair value of financial instruments where appropriate. The assumptions we use — including the discount rate and estimates of cash flows — can significantly affect the fair value. These values are estimates and may not match the amounts we would realize upon sale or settlement of our financial positions. Cash Equivalents Cash equivalents are investments with maturities of 90 days or less at the date of purchase. We state cash equivalents at cost, which approximates market. Concentration of Risk We disclose customers that represent a concentration of risk. As of December 31, 2023, and December 31, 2022, no customer accounted for 10 percent or more of our net sales. ITEMS RELATED TO OPERATIONS Key items related to operations include revenue recognition, inventories, shipping and handling costs, income taxes, pension and other post-employment benefit plans and contingent liabilities. Revenue Recognition Refer to Note 3: Revenue Recognition for details on how we account for revenue. WEYERHAEUSER COMPANY > 2023 ANNUAL REPORT AND FORM 10-K 65 Inventories We state inventories at the lower of cost or net realizable value. Cost includes labor, materials and production overhead. LIFO applies to major inventory products held at our U.S. domestic locations. We began to use the LIFO method for domestic products in the 1940s as required to conform with the tax method elected. Subsequent acquisitions of entities added new products under the moving average cost or FIFO — the first-in, first-out — methods and those products continue to be recognized under those methods. The moving average cost or FIFO method applies to the balance of our domestic raw material and product inventories, all material and supply inventories and all foreign inventories. Shipping and Handling Costs We classify shipping and handling costs in “Costs of sales” in our Consolidated Statement of Operations. Income Taxes We account for income taxes under the asset and liability method. Unrecognized tax benefits represent potential future funding obligations to taxing authorities if uncertain tax positions we have taken on previously filed tax returns are not sustained. Accrued interest and penalties related to unrecognized tax benefits are recognized as a component of income tax expense. We recognize deferred tax assets and liabilities to reflect: •future tax consequences due to differences between the carrying amounts for financial reporting purposes and the tax bases of certain items and •net operating loss and tax credit carryforwards. To measure deferred tax assets and liabilities, we: •determine when the differences between carrying amounts and tax bases of affected items are expected to be recovered or resolved and •use enacted tax rates expected to apply to taxable income in those years. Pension and Other Post-Employment Benefit Plans We recognize the overfunded or underfunded status of our defined benefit pension and other post-employment benefit plans on our Consolidated Balance Sheet and recognize changes in the funded status through comprehensive income (loss) in the year in which the changes occur. Actuarial valuations determine the amount of the pension and other post-employment benefit obligations and the net periodic benefit cost we recognize. The net periodic benefit cost includes: •cost of benefits provided in exchange for employees’ services rendered during the year; 66 •interest cost of the obligations; •expected long-term return on plan assets; •gains or losses on plan settlements and curtailments; •amortization of prior service costs and plan amendments over the average remaining service period of the active employee group covered by the plans or the average remaining life expectancy in situations where the participants affected by the plan amendment are inactive and •amortization of cumulative unrecognized net actuarial gains and losses — generally in excess of 10 percent of the greater of the benefit obligation or the combination of market- related and fair value of plan assets at the beginning of the year — over the average remaining service period of the active employee group covered by the plans or the average remaining life expectancy in situations where the plan participants are inactive. Pension plans. We have defined benefit pension plans covering approximately 40 percent of our employees. Determination of benefits differs for salaried, hourly and union employees as follows: •Salaried employee benefits are based on each employee’s highest monthly earnings for five consecutive years during the final 10 years before retirement. •Hourly and union employee benefits generally are stated amounts for each year of service. •Union employee benefits are set through collective-bargaining agreements. We contribute to our U.S. and Canadian pension plans according to established funding standards. The funding standards for the plans are: •U.S. pension plans — according to the Employee Retirement Income Security Act of 1974 and •Canadian pension plans — according to the applicable provincial pension act and the Income Tax Act. Post-employment benefits other than pensions. We provide certain post-employment healthcare and life insurance benefits for some retired employees. In some cases, we pay a portion of the cost of the benefit. Note 8: Pension and Other Post- Employment Benefit Plans provides additional information about our post-employment benefit plans. Estimates for pension and other post-employment benefit plans. Estimates we use in accounting for our pension and other post-employment benefit plans include the: •fair value of our plan assets; •expected long-term rate of return on plan assets and •discount rates. At the end of every year, we review our estimates with external advisers and make adjustments as appropriate. We use these estimates to calculate plan asset and liability information as of year-end as well as pension and post-employment expense for the following year. Actual experience that differs from our estimates and subsequent changes in our estimates could have a significant effect on our financial position, results of operations and cash flows. Fair value of plan assets. Plan assets are assets of the pension plan trusts that fund the benefits provided under the pension plans. The fair value of our plan assets estimates the amount that would be received if we were to sell each asset in an orderly transaction between market participants at the reporting date. We estimate the fair value of these assets based on the information available during the year-end reporting process. Refer to Note 8: Pension and Other Post-Employment Benefit Plans for information about the assets held within our pension plans and their related valuation methods. Expected long-term rate of return on plan assets. Our expected long-term rate of return is our estimate of the return that our plan assets will earn over time. This rate is used in determining the net periodic benefit or cost we recognize for our plans. Factors we consider in determining our expected long-term rate of return include: •historical returns for a portfolio of assets similar to our expected allocation and •expected future performance of similar asset classes. The actual return on plan assets in any given year may vary from our expected long-term rate of return. Actual returns on plan assets affect the funded status of the plans. Differences between actual returns on plan assets and the expected long- term rate of return are reflected as adjustments to accumulated other comprehensive loss, a component of total equity. Discount rates. Discount rates are used to estimate the net present value of our plan obligations. The discount rates are determined at the measurement date by matching current spot rates of high-quality corporate bonds with maturities similar to the timing of expected cash outflows for benefits. Contingent Liabilities We are subject to lawsuits, investigations and other claims related to environmental remediation, product and other matters, and are required to assess the likelihood of any adverse judgments or outcomes to these matters, as well as the amount or range of potential loss. We record contingent liabilities when: •it becomes probable that a loss has been incurred and •the amount of loss can be reasonably estimated. Assessing probability of loss and estimating the amount of loss can require analysis of multiple factors, such as: •historical experience, •evaluations of relevant legal and environmental authorities and regulations, •judgments about the potential actions of third-party claimants and courts and •consideration of potential environmental remediation methods. In addition to contingent liabilities recorded for probable losses, we disclose contingent liabilities when there is a reasonable possibility that a loss may have been incurred. Recorded contingent liabilities are based on the best information available and actual losses in any future period are inherently uncertain. Future expenditures for environmental remediation obligations are not discounted to their present value. If estimated probable future losses or actual losses exceed our recorded liability for such claims, we record additional charges. These exposures and proceedings can be significant and the ultimate outcomes could be material to our operating results or cash flows in any given period. Recoveries of environmental remediation costs from other parties are recorded as assets when the recovery is deemed probable and does not exceed the amount of losses previously recorded. See Note 13: Legal Proceedings, Commitments and Contingencies for more information. NEW ACCOUNTING PRONOUNCEMENTS Segment Reporting In November 2023, the FASB issued Accounting Standards Update (ASU) 2023-07,“Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures”, which expands annual and interim disclosure requirements for reportable segments, primarily through enhanced disclosures about significant segment expenses. The new guidance is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The adoption of the new guidance will not impact our Consolidated Statement of Operations, Consolidated Balance Sheet or Consolidated Statement of Cash Flows. We plan to incorporate these expanded disclosures beginning in fourth quarter 2024. Income Taxes In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures”, which expands annual income tax disclosures to disaggregate rate reconciliations and income taxes paid by nature and jurisdiction. The new guidance is effective for annual periods WEYERHAEUSER COMPANY > 2023 ANNUAL REPORT AND FORM 10-K 67 beginning after December 15, 2024, with early adoption permitted. ASU 2023-09 should be applied on a prospective basis, however, retrospective application is permitted. The adoption of the new guidance will not impact our Consolidated Statement of Operations, Consolidated Balance Sheet or Consolidated Statement of Cash Flows.

NOTE 3: REVENUE RECOGNITION A majority of our revenue is derived from sales of delivered logs and manufactured wood products. We account for revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers. PERFORMANCE OBLIGATIONS A performance obligation, as defined in ASC Topic 606, is a promise in a contract to transfer a distinct good or service to a customer. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue at the point in time, or over the period, in which the performance obligation is satisfied. Performance obligations associated with delivered log sales are typically satisfied when the logs are delivered to our customers’ mills or delivered to an ocean vessel in the case of export sales. Performance obligations associated with the sale of wood products are typically satisfied when the products are shipped. We have elected, as an accounting policy, to treat shipping and handling that is performed after a customer obtains control of the product as an activity required to fulfill the promise to transfer the good; therefore we will not evaluate this requirement as a separate performance obligation. Customers are generally invoiced shortly after logs are delivered or after wood products are shipped, with payment generally due within a month or less of the invoice date. ASC Topic 606 requires entities to consider significant financing components of contracts with customers, though allows for the use of a practical expedient when the period between satisfaction of a performance obligation and payment receipt is one year or less. Given the nature of our revenue transactions, we have elected to utilize this practical expedient. Performance obligations associated with real estate sales are generally met when placed into escrow and all conditions of closing have been satisfied. CONTRACT ESTIMATES Substantially all of our performance obligations are satisfied as of a point in time. Therefore, there is little judgment in determining when control transfers for our business segments as described above. The transaction price for log sales generally equals the amount billed to our customer for logs delivered during the accounting period. For the limited number of log sales subject to a long- term supply agreement, the transaction price is variable but is known at the time of billing. For wood products sales, the transaction price is generally the amount billed to the customer for the products shipped but may be reduced slightly for estimated cash discounts and rebates. There are no significant contract estimates related to the real estate business. WEYERHAEUSER COMPANY > 2023 ANNUAL REPORT AND FORM 10-K 69 CONTRACT BALANCES In general, customers are billed and a receivable is recorded as we ship and/or deliver wood products and logs. We generally receive payment shortly after products have been received by our customers. Contract asset and liability balances are immaterial. For real estate sales, the company receives the entire consideration in cash at closing.

This transaction was structured as a like-kind exchange along with the acquisition discussed below. As a result of the sale, we recorded an $84 million gain in the Timberlands segment in our Consolidated Statement of Operations. This sale was not considered a strategic shift that had, or will have, a major effect on our operations or financial results and therefore did not meet the requirements for presentation as discontinued operations. On December 20, 2023, we completed the purchase of 61 thousand acres of timberlands across the Carolinas and Mississippi for $159 million, which is net of purchase price adjustments. As a result of the purchase, we recorded $157 million of timberland assets in “Timber and timberlands at cost, less depletion” and $2 million of related assets in “Property and equipment, net” on our Consolidated Balance Sheet. MISSISSIPPI ACQUISITION On July 19, 2023, we completed the purchase of 22 thousand acres of Mississippi timberlands for approximately $60 million. We recorded $59 million of timberland assets in “Timber and timberlands at cost, less depletion” and $1 million of related assets in “Property and equipment, net” on our Consolidated Balance Sheet. CAROLINAS ACQUISITION On May 18, 2022, we completed the purchase of 81 thousand acres of North and South Carolina timberlands for approximately $265 million. We recorded $263 million of timberland assets in “Timber and timberlands at cost, less depletion” and $2 million of related assets in “Property and equipment, net” on our Consolidated Balance Sheet. WASHINGTON DIVESTITURE On July 7, 2021, we completed the sale of 145 thousand acres of timberlands in the North Cascades region of Washington for $261 million in cash proceeds, which is net of purchase price adjustments and closing costs. This transaction was structured as a like-kind exchange along with the Alabama acquisition discussed below. As a result of the sale, a gain of $32 million was recorded in the Timberlands segment in our Consolidated Statement of Operations. This divestiture was not considered a strategic shift that had, or will have, a major effect on our operations or financial results and therefore did not meet the requirements for presentation as discontinued operations. ALABAMA ACQUISITION On April 27, 2021, we completed the purchase of 69 thousand acres of southwest Alabama timberlands for approximately $149 million. We recorded $148 million of timberland assets in “Timber and timberlands at cost, less depletion” and $1 million of related assets in “Property and equipment, net” on our Consolidated Balance Sheet. As discussed above, this transaction was structured as a like-kind exchange. NOTE 5: NET EARNINGS PER SHARE Our basic and diluted earnings per share for the last three years were: •$1.15 in 2023, •$2.53 in 2022 and •$3.48 and $3.47, respectively, in 2021. HOW WE CALCULATE BASIC AND DILUTED NET EARNINGS PER SHARE Basic earnings per share is net earnings available to common shareholders divided by the weighted average number of our outstanding common shares, including stock equivalent units where there is no circumstance under which those shares would not be issued. Diluted earnings per share is net earnings available to common shareholders divided by the sum of the: •weighted average number of our outstanding common shares and •the effect of our outstanding dilutive potential common shares. Dilutive potential common shares may include: •outstanding stock options, •restricted stock units and •performance share units.

NOTE 8: PENSION AND OTHER POST-EMPLOYMENT BENEFIT PLANS This note provides details about defined benefit and defined contribution plans we sponsor for our employees. The “Pension and Other Post-Employment Benefit Plans” section of Note 1: Summary of Significant Accounting Policies provides information about how we account for pension and other post-employment plans and benefits. PLANS WE SPONSOR OVERVIEW OF PLANS The defined benefit pension plans we sponsor in the U.S. and Canada differ according to each country’s requirements. In the U.S., we have plans that qualify under the Internal Revenue Code (qualified plans), as well as plans for select employees that provide additional benefits not qualified under the Internal Revenue Code (nonqualified plans). In Canada, we have plans that are registered under the Income Tax Act and applicable provincial pension acts (registered plans), as well as nonregistered plans for select employees that provide additional benefits that may not be registered under the Income Tax Act or provincial pension acts (nonregistered plans). We also sponsor other post-employment benefit (OPEB) plans in the U.S. and Canada, including retiree medical and life insurance plans. Our defined benefit pension plans were closed to newly hired and rehired salaried and non-union employees effective January 1, 2014, and were closed to union employees at various dates over the course of 2014 to 2019. We sponsor various defined contribution plans for our U.S. and Canadian salaried and hourly employees. Our contributions to these plans were $35 million, $31 million and $27 million in 2023, 2022 and 2021, respectively. Actions to Reduce Pension Plan Obligations As part of our continued efforts to reduce pension plan obligations, we transferred approximately $420 million of Canadian registered assets and liabilities to insurance companies through the purchase of a group annuity contract in December 2022 (2022 Retiree Annuity Purchase). In connection with this transaction, we recorded a noncash pretax settlement charge of $205 million during 2022. This settlement charge accelerated the recognition of previously unrecognized losses in “Accumulated Other Comprehensive Loss,” that would have been recognized in subsequent periods. Given the timing of the 2022 Retiree Annuity Purchase, the plan remeasurement triggered as a result of the transaction was conducted as part of our annual valuation process. WEYERHAEUSER COMPANY > 2023 ANNUAL REPORT AND FORM 10-K 73 FUNDED STATUS OF PLANS The funded status of the plans we sponsor is determined by comparing the projected benefit obligation with the fair value of plan assets at the end of the year. The following table demonstrates how our plans’ funded status is reflected on our Consolidated Balance Sheet.

(2) Includes adjustments for final fair value of plan assets. (3) Assets and liabilities on our Consolidated Balance Sheet are different from the cumulative income or expense that we have recorded associated with the plans. The differences are actuarial gains and losses and prior service costs and credits that are deferred and amortized into periodic benefit costs in future periods. Unamortized amounts are recorded in “Accumulated Other Comprehensive Loss”, which is a component of total equity on our Consolidated Balance Sheet. The “Accumulated Other Comprehensive Loss” section of Note 14: Shareholders’ Interest details changes in these amounts by component. (4) For pension plans with a projected benefit obligation exceeding plan assets, the projected benefit obligation and fair value of plan assets were $2.1 billion and $1.7 billion at December 31, 2023, respectively, and $2.1 billion and $1.8 billion at December 31, 2022, respectively. For pension plans with an accumulated benefit obligation exceeding plan assets, the accumulated benefit obligation and fair value of plan assets were $2.1 billion and $1.7 billion at December 31, 2023, respectively, and $2.0 billion and $1.8 billion at December 31, 2022, respectively. (5) For the U.S. defined benefit plans, the discount rate assumption was 5.2% and 5.4% for 2023 and 2022, respectively. For the Canadian defined benefit plans, the discount rate assumption was 4.7% and 5.3% for 2023 and 2022, respectively. For U.S. OPEB plans, the discount rate assumption was 5.1% and 5.4% for 2023 and 2022, respectively. For Canadian OPEB plans, the discount rate assumption was 4.6% and 5.3% for 2023 and 2022, respectively. For lump sum distributions (for U.S. qualified salaried and nonqualified plans only), the interest and mortality assumptions are the same as those mandated by the Pension Protection Act of 2006 for benefits commencing in the current year. (6) For the U.S. defined benefit plans, the rate of compensation increase assumption for both 2023 and 2022 was between 2.00%—13.00% for salaried participants and was decreasing with participant age. For the Canadian defined benefit plans, the rate of compensation increase assumption was 1.00%—2.75% and 2.00%—2.75% for salaried and hourly participants, respectively, for both 2023 and 2022. (7) U.S. qualified salaried and nonqualified plans only. (8) For U.S. OPEB plans, the healthcare cost trend rate assumption for the next year for Pre-Medicare was 7.25% and 5.70% for 2023 and 2022, respectively. The ultimate healthcare cost trend rate was 4.50% for both 2023 and 2022 and the assumption for the year the ultimate healthcare cost trend rate is reached was 2035 and 2037 in 2023 and 2022, respectively. For Canadian OPEB plans, the healthcare cost trend rate was 5.13% for 2023 and 5.20% for 2022. The ultimate healthcare cost trend rate was 4.00% and the assumption for the year the ultimate healthcare cost trend rate is reached was 2040 for both 2023 and 2022. 74 PENSION ASSETS Our Investment Policies and Strategies Assets within our U.S. and Canadian pension trusts were invested as follows: Our investment policies, strategies and advisory agreements guide and direct how the funds are managed for the benefit plans we sponsor. These funds include our: •U.S. Pension Trust — funds our U.S. qualified pension plans; •Canadian Pension Trust — funds our Canadian registered pension plans and •Retirement Compensation Arrangements — fund a portion of our Canadian nonregistered pension plans. U.S. and Canadian Pension Trusts In 2018, we began to shift pension plan assets to an allocation that more closely aligns with our pension plan liability profile. Our former investment strategy included investments primarily in hedge funds and private equity funds. These asset classes are now in redemption and run-off mode. However, given the long-term nature of these investments, they will continue to comprise a portion of the plan assets for several years. We expect all investments in redemption to be redeemed at amounts materially consistent with their net asset values (NAV). As these investments are redeemed or liquidated, cash proceeds available for investment will be invested in accordance with our current investment strategy. Our investment strategy targets a percentage allocation to growth assets and a percentage allocation to liability hedging assets based on each plan’s funded status. We expect to increase the allocation to liability hedging assets over time as the funded status of the pension plans improves. Growth assets may include investments in global equities, hedge funds (which are in redemption), private equity assets (which are in run-off mode), fixed income and real estate. Liability hedging assets may include corporate credit and government issued fixed income securities as well as treasury futures selected to align with the plan liabilities.

(2) Public equity investments are valued at exit prices quoted in active markets. (3) Fixed income investments include publicly traded corporate and government issued debt. These bonds have varying maturities, credit quality and sector exposure and are selected to align with the duration of our plan liabilities. Additionally, our fixed income portfolio includes repurchase agreements, which represent short-term borrowings to hedge against interest rate risk. We have an obligation to return the cash related to these borrowings in accordance with the agreements, which are collateralized by our government bonds. Fixed income investments are valued at exit prices quoted in active or non-active markets or based on observable inputs. (4) Hedge funds and related investments are privately-offered managed pools primarily structured as limited liability entities. General members or partners of these limited liability entities serve as portfolio managers and are thus responsible for the fund’s underlying investment decisions. Underlying investments within these funds may include long and short public and private equities, corporate, mortgage and sovereign debt, options, swaps, forwards and other derivative positions. These funds have varying degrees of leverage, liquidity and redemption provisions. (5) These investments are primarily valued based on the NAVs of the funds. These values represent the per-unit price at which new investors are permitted to invest and existing investors are permitted to exit. When NAVs as of the end of the year have not been received, we estimate fair value by adjusting the most recently reported NAVs for market events and cash flows between the interim date and the end of the year. (6) Private equity and related investments include both investments in private equity and investments in mezzanine distressed, co-investments and other structures. Private equity funds generally participate in buyout and venture capital strategies through unlisted equity and debt instruments. These funds may also borrow at the underlying entity level. Mezzanine and distressed funds generally invest in the debt of public or private companies with additional participation through warrants or other equity options. (7) Derivative instruments have historically been comprised of swaps, futures, forwards or options. At December 31, 2023, only a small amount of risk-mitigating futures remain in the portfolio. Derivative instruments are valued based upon valuation statements received from each derivative’s counterparty. Retirement Compensation Arrangements Retirement compensation arrangements fund a portion of our Canadian nonregistered pension plans. As required by Canadian tax rules, approximately 50 percent of these assets are invested into a non-interest bearing refundable tax account held by the Canada Revenue Agency. This portion of the portfolio does not earn returns. The remaining portion is invested in a portfolio of equities. Managing Risk Investments and contracts are subject to risks including market price, interest rate, credit, currency and liquidity risks. We mitigate these risks to our pension plan asset portfolios through advisory agreements, investment in diversified WEYERHAEUSER COMPANY > 2023 ANNUAL REPORT AND FORM 10-K 75 portfolios, inclusion of fixed income investments that align with plan liabilities and investment in assets designed to address both currency and liquidity considerations. In addition, we and our investment advisers perform regular monitoring with ongoing qualitative assessments, quantitative assessments and investment and operational due diligence. Valuation of Our Plan Assets Pension assets are stated at fair value or NAV. Fair value is based on the amount that would be received to sell an asset or paid to settle a liability in an orderly transaction between market participants at the reporting date. We consider both observable and unobservable inputs that reflect assumptions applied by market participants when setting the exit price of an asset or liability in an orderly transaction within the principal market for that asset or liability. We value the pension plan assets based upon the observability of exit pricing inputs and classify pension plan assets based upon the lowest level input that is significant to the fair value measurement of the pension plan assets in their entirety. Refer to Note 1: Summary of Significant Accounting Policies for details on the fair value hierarchy. The availability of observable market data is monitored to assess the appropriate classification of financial instruments within the fair value hierarchy. Changes in economic conditions or model-based valuation techniques may require the transfer of financial instruments from one fair value level to another. In such instances, the transfer is reported at the beginning of the reporting period. We evaluate the significance of transfers between levels based upon the nature of the financial instrument and size of the transfer relative to total net assets available for benefits. Investments for which fair value is measured using the NAV per share as a practical expedient are not categorized within the fair value hierarchy. The net pension plan assets, when categorized in accordance with this fair value hierarchy, are as follows.

Additionally, December 31, 2023 and 2022 exclude $3 million and $14 million of accrued liabilities, respectively. (2) Derivative instruments include futures contracts. The fair value and aggregate notional value of these contracts were $1 million and $393 million at December 31, 2023, respectively, and less than $1 million and $418 million at December 31, 2022, respectively. 76 ACTIVITY OF PLANS Net Periodic Benefit Cost Our net periodic benefit cost and the assumptions used to estimate it are shown in the following table.

For the Canadian defined benefit plans, the discount rate assumption was 5.30%, 3.10% and 2.50% for 2023, 2022 and 2021, respectively. For U.S. OPEB plans, the discount rate assumption was 5.40%, 2.60% and 2.10%, for 2023, 2022 and 2021, respectively. For Canadian OPEB plans, the discount rate assumption was 5.30%, 3.00% and 2.40% for 2023, 2022 and 2021, respectively. For lump sum distributions (for U.S. qualified salaried and nonqualified plans only), the interest and mortality assumptions are the same as those mandated by the Pension Protection Act of 2006 for benefits commencing in the current year. (2) Determining our expected return requires a high degree of judgment. We consider actual pension fund asset performance over multiple years, and current and expected valuation levels in the global equity and credit markets. Historical fund returns are used as a base and we place added weight on more recent pension plan asset performance. (3) For the U.S. defined benefit plans, the rate of compensation increase assumption for 2023, 2022 and 2021 was between 2.00%—13.00% for salaried participants and was decreasing with participant age. For the Canadian defined benefit plans, the rate of compensation increase assumption for salaried participants was 1.00%—2.75% for 2023 and 3.25% for 2022 and 2021. The rate of compensation increase assumption for hourly participants was 2.00%—2.75% for 2023 and 3.00% for 2022 and 2021. (4) U.S. qualified salaried and nonqualified plans only. (5) For OPEB plans during 2023, the assumed weighted healthcare cost trend rate was 5.70%, 4.50% and 5.20% for U.S. Pre-Medicare participants, U.S. HRA participants and Canadian OPEB plans, respectively. Pension Plan Contributions and Benefit Payments Established funding standards govern the funding requirements for our qualified and registered pension plans. We fund the benefit payments of our nonqualified and nonregistered plans as benefit payments come due. During 2023, we made contributions and/or benefit payments of $12 million for our U.S. nonqualified pension plans, $1 million for our Canadian nonregistered pension plans and $1 million for our Canadian registered plans. During 2024, based on estimated year-end asset values and projections of plan liabilities, we expect to make contributions and/or benefit payments of approximately: •$10 million for our U.S. nonqualified pension plans, •$2 million for the Canadian non-registered plans and •$1 million for our Canadian registered plan (required contribution). We do not anticipate contributions being required for our U.S. qualified pension plan for 2024. OPEB Benefit Payments During 2023, we contributed $5 million and $1 million to our U.S. and Canadian OPEB plans, respectively. In 2024, we expect to make contributions of $7 million in total for our U.S. and Canadian OPEB plans, including $4 million expected to be required to cover benefit payments under collectively bargained contractual obligations. 2024 2025 2026 2027 2028 2029-2033 PENSION OPEB $ $ $ $ $ $ 149 $ 150 $ 154 $ 155 $ 157 $ 806 $ 11 10 9 9 8 33 UNION-ADMINISTERED MULTIEMPLOYER BENEFIT PLANS We contribute to multiemployer defined benefit plans under the terms of collective-bargaining agreements.

Borrowings will bear interest at a floating rate based on either the adjusted term Secured Overnight Financing Rate (SOFR) plus a spread or a mutually agreed upon base rate plus a spread. As of December 31, 2023 and 2022, we had no outstanding borrowings on the revolving credit facility and had our full $1.5 billion available. We were in compliance with the revolving credit facility covenants as of December 31, 2023 and December 31, 2022. LETTERS OF CREDIT AND SURETY BONDS The amounts of letters of credit and surety bonds we have entered into as of the end of the last two years are included in the following table: DOLLAR AMOUNTS IN MILLIONS Letters of credit Surety bonds DECEMBER 31, 2023 DECEMBER 31, 2022 $ $ 34 $ 129 $ 34 121 Our compensating balance requirement for our letters of credit was $3 million as of December 31, 2023 and $4 million as of December 31, 2022. 78 DEBT ISSUED AND EXTINGUISHED Over the course of 2023, we refinanced approximately $1 billion of debt. In December 2023, we entered into a $250 million senior unsecured term loan that will mature in December 2028. Net proceeds after fees were $249 million. Borrowings will bear interest at a floating rate based on either the adjusted term SOFR plus a spread or a mutually agreed upon base rate plus a spread. The facility also provides flexibility to enter into a mutually agreed fixed rate. In December 2023, we repaid our $860 million 5.207 percent private note at maturity, funded by cash on hand, including the proceeds from our short-term investments which matured in fourth quarter 2023. In July 2023, we repaid $118 million of our 7.125 percent notes at maturity. In May 2023, we completed an offering of debt securities by issuing $750 million of 4.750 percent notes due in May 2026. The net proceeds after deducting the discount, underwriting fees and issuance costs were $743 million. In March 2022, we completed a series of transactions that lowered our weighted average interest rate and extended our weighted average maturity by issuing $900 million in notes and using the net proceeds plus cash on hand to close cash tender offers for $931 million of principal in higher interest rate notes. We issued $450 million of 3.375 percent notes due in March 2033 and $450 million of 4.00 percent notes due in March 2052. The net proceeds after deducting the discount, underwriting fees and issuance costs were $444 million and $437 million, respectively. The net proceeds were used to retire $592 million of our 7.375 percent notes due in March 2032, $161 million of our 8.50 percent notes due in January 2025, $73 million of our 7.125 percent notes due in July 2023, $65 million of our 7.95 percent notes due in March 2025 and $40 million of our 7.85 percent notes due in July 2026. We paid holders an aggregate $1.2 billion in cash reflecting principal, premium to par and tender premium. A net pretax charge of $276 million ($207 million after-tax) was included in our Consolidated Statement of Operations in first quarter 2022 for premiums to retire $931 million of principal plus unamortized debt issuance costs and unamortized debt discounts in connection with the early debt retirement. Amounts of Long-Term Debt Due Annually for the Next Five Years and Thereafter In October 2021, we repaid our $150 million 9.00 percent notes at maturity. In May 2021, we repaid our $225 million variable-rate term loan that was scheduled to mature in July 2026.

We believe that our variable-rate long term debt and line of credit instruments have net carrying values that approximate their fair value with only insignificant differences. The inputs to the valuations of our long-term debt are based on market data obtained from independent sources or information derived principally from observable market data. The difference between the fair value and the carrying value represents the theoretical net premium or discount we would pay or receive to retire all debt at the measurement date. FAIR VALUE OF OTHER FINANCIAL INSTRUMENTS We believe that our other financial instruments, including cash and cash equivalents, short-term investments, mutual fund investments held in grantor trusts, receivables and payables, have net carrying values that approximate their fair values with only insignificant differences. This is primarily due to the short- term nature of these instruments and the allowance for doubtful accounts. WEYERHAEUSER COMPANY > 2023 ANNUAL REPORT AND FORM 10-K 79 NOTE 13: LEGAL PROCEEDINGS, COMMITMENTS AND CONTINGENCIES This note provides details about our: •legal proceedings, •environmental matters and •commitments and other contingencies. LEGAL PROCEEDINGS We are party to various legal proceedings arising in the ordinary course of business. We are not currently a party to any legal proceeding that management believes could have a material adverse effect on our Consolidated Balance Sheet, Consolidated Statement of Operations or Consolidated Statement of Cash Flows. ENVIRONMENTAL MATTERS Site Remediation Under the federal Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) — commonly known as the “Superfund” — and similar state laws, we are a party to various proceedings related to the cleanup of hazardous waste sites and have been notified that we may be a potentially responsible party related to the cleanup of other hazardous waste sites for which proceedings have not yet been initiated. We have received notification from the Environmental Protection Agency (EPA) and have acknowledged that we are a potentially responsible party in a portion of the Kalamazoo River Superfund site in southwest Michigan. Our involvement in the remediation site is based on our operation of the Plainwell, Michigan mill, located within the remediation site, from 1954 to 1970. Several other companies also have been deemed potentially responsible parties as past or present owners or operators of facilities within the site, or as arrangers under CERCLA. We cooperated with other parties to jointly implement an administrative order issued by the EPA on April 14, 2016, with respect to a portion of the site comprising a stretch of the river approximately 1.7 miles long referred to as the Otsego Township Dam Area. During third quarter 2018, implementation of this administrative order was completed. In 2010, the company, along with others, was named as a defendant by Georgia-Pacific Consumer Products LP, Fort James Corporation and Georgia-Pacific LLC in an action seeking contribution under CERCLA for remediation costs relating to a certain area within the site. On March 29, 2018, the U.S. District Court issued an opinion and order assigning the company responsibility for 5 percent of approximately $50 million in past costs incurred by the plaintiffs. The remaining 95 percent of this pool of past costs incurred was 80 allocated to the plaintiffs and other defendants. The opinion and order does not establish allocation for future remediation costs, and accordingly, we may incur additional costs in connection with future remediation tasks for other areas of the site. In 2022, the Sixth Circuit Court of Appeals reversed the District Court opinion, finding that Georgia-Pacific’s claims for cost contributions were time barred by the statute of limitations. Georgia-Pacific filed a petition for writ of certiorari with the U.S. Supreme Court, which was denied during fourth quarter 2023 and redirected to the district court for further proceedings. As a result, Georgia-Pacific relinquished further appeals and the company was found not responsible for prior costs incurred by Georgia-Pacific. We have established accruals for estimated remediation costs on the active Superfund sites and other sites for which we are a potentially responsible party. These accruals are recorded in “Accrued liabilities” and “Other liabilities” on our Consolidated Balance Sheet. Changes in the Accrual for Environmental Remediation DOLLAR AMOUNTS IN MILLIONS Accrual balance as of December 31, 2022 Charges and adjustments, net Payments Accrual balance as of December 31, 2023 We change our accrual to reflect: $ $ 64 17 (6) 75 •new information on any site concerning implementation of remediation alternatives, •updates on prior cost estimates and new sites and •costs incurred to remediate sites. Estimates. We believe it is reasonably possible, based on currently available information and analysis, that remediation costs for all identified sites may exceed our existing accruals by up to $213 million. This estimate, in which those additional costs may be incurred over several years, is the upper end of the range of reasonably possible additional costs. The estimate: •is much less certain than the estimates on which our accruals currently are based and •uses assumptions that are less favorable to us among the range of reasonably possible outcomes. In estimating our current accruals and the possible range of additional future costs, we: •assumed we will not bear the entire cost of remediation of every site, •took into account the ability of other potentially responsible parties to participate and •considered each party’s financial condition and probable contribution on a per-site basis. We have not recorded any amounts for potential recoveries from insurance carriers. Asset Retirement Obligations We have obligations associated with the retirement of tangible long-lived assets consisting primarily of reforestation obligations related to forest management licenses in Canada and obligations to close and cap landfills. Some of our sites have asbestos containing materials. We have met our current legal obligation to identify and manage these materials. In situations where we cannot reasonably determine when asbestos containing materials might be removed from the sites, we have not recorded an accrual because the fair value of the obligation cannot be reasonably estimated. As of December 31, 2023, and December 31, 2022, we had an asset retirement obligation of $36 million and $32 million, respectively. These obligations are recorded in “Accrued liabilities” and “Other liabilities” on our Consolidated Balance Sheet.

PREFERRED AND PREFERENCE SHARES We had no preferred shares or preference shares outstanding as of December 31, 2023 or December 31, 2022. We have authorization to issue 7 million preferred shares with a par value of $1.00 per share and 40 million preference shares with a par value of $1.00 per share. COMMON SHARES The number of common shares we have outstanding changes when: •new shares are issued, •stock options are exercised, •restricted stock units or performance share units vest, •stock equivalent units are settled in common shares, •shares are tendered, •shares are repurchased or •shares are canceled.

Concurrently, the board terminated the remaining repurchase authorization under the share repurchase program approved by the board in February 2019 (the 2019 Repurchase Program). We repurchased 4,054,952 common shares for approximately $125 million (including transaction fees) under the 2021 Repurchase Program during 2023. As of December 31, 2023, we had remaining authorization of $252 million for future share repurchases. During 2022, we repurchased 15,983,097 common shares for approximately $550 million (including transaction fees) under the 2021 Repurchase Program. During 2021, we repurchased 780,228 common shares for approximately $26 million (including transaction fees) under the 2019 Repurchase Program and 1,949,496 common shares for approximately $74 million (including transaction fees) under the 2021 Repurchase Program. All common stock repurchases under the 2019 Repurchase Program and 2021 Repurchase Program were made in open- market transactions. We record share repurchases upon trade date as opposed to the settlement date when cash is disbursed. We record a liability for repurchases that have not yet been settled as of period end. There were 13,866 unsettled shares (approximately $1 million) as of December 31, 2023. There were 223,548 unsettled shares (approximately $7 million) as of December 31, 2022.

NOTE 15: SHARE-BASED COMPENSATION This note provides details about: •our Long-Term Incentive Compensation Plan (2022 Plan), •how we account for share-based awards, •tax benefits of share-based awards, •types of share-based compensation, •unrecognized share-based compensation and •deferred compensation stock equivalent units. Share-based compensation expense was: •$36 million in 2023, •$33 million in 2022 and •$30 million in 2021. 82 •restricted stock, •restricted stock units (RSUs), •performance shares and •performance share units (PSUs). We may issue future grants of up to 21 million shares under the 2022 Plan. We also have the right to reissue forfeited and expired grants. The Compensation Committee of our board of directors annually establishes an overall pool of stock awards available for grants based on performance. For stock-settled awards, we issue new stock into the marketplace and generally do not repurchase shares in connection with issuance of new awards. Our common shares would increase by approximately 25 million shares if all share-based awards were exercised or vested. These include: •all outstanding share-based awards at December 31, 2023 and •all remaining RSUs and PSUs that could be granted under the 2022 Plan. HOW WE ACCOUNT FOR SHARE-BASED AWARDS We recognize the cost of share-based awards using a fair-value- based measurement in our Consolidated Statement of Operations over the required service period — generally the period from the date of the grant to the date when it is fully vested. Special situations include: •Awards that vest upon retirement — the required service period ends on the date an employee is eligible for retirement, including early retirement. •Awards that continue to vest following job elimination or the sale of a business — the required service period ends on the date the employment from the company is terminated. In these special situations, compensation expense from share- based awards is recognized over a period that is shorter than the stated vesting period. Forfeitures are recognized in compensation expense as they occur. TAX BENEFITS OF SHARE-BASED AWARDS Our total income tax benefit from share-based awards recognized in our Consolidated Statement of Operations for the last three years was: •$5 million in 2023, •$5 million in 2022 and •$4 million in 2021. Tax benefits from share-based awards are accrued as stock compensation expense and realized when restricted shares, performance shares, RSUs and PSUs vest. TYPES OF SHARE-BASED COMPENSATION Our share-based compensation is in the form of RSUs and PSUs. Activity The following table shows our RSU activity for 2023: Nonvested at December 31, 2022 Granted Vested Forfeited RESTRICTED STOCK UNITS (IN THOUSANDS) WEIGHTED AVERAGE GRANT-DATE FAIR VALUE 1,573 $ 844 $ (679) $ (37) $ 1,701 $ 34.93 33.81 32.46 35.67 35.34 RESTRICTED STOCK UNITS Nonvested at December 31, 2023(1) Through the 2022 Plan, we award RSUs — grants that entitle the holder to shares of our stock as the award vests. The Details Our RSUs granted in 2023, 2022 and 2021 generally: •vest ratably over four years; •immediately vest in the event of death or disability while employed; •continue to vest upon retirement at an age of at least 62, in accordance with the vesting terms of the awards, but a portion of the award is forfeited if retirement occurs before the one-year anniversary of the grant; •continue vesting for one year in the event of involuntary termination due to job elimination; •immediately vest in the case of a change of control, if the successor company does not assume the award or, if assumed, within two years of the effective date of the change in control the recipient is terminated other than for cause or leaves for good reason (as defined in the award terms and conditions) and •will be forfeited upon termination of employment in all other situations including early retirement prior to age 62. Our Accounting The fair value of our RSUs is the market price of our stock on the grant date of the awards. We generally record share-based compensation expense for RSUs over the four-year vesting period. Generally, for RSUs that continue to vest following the termination of employment, we record the share-based compensation expense over a required service period that is less than the stated vesting period. (1) As of December 31, 2023, there were approximately 136 thousand RSUs that had met the requisite service period and will be released as identified in the grant terms. The weighted average grant-date fair value for RSUs was: •$33.81 in 2023, •$42.02 in 2022 and •$33.62 in 2021. The total grant-date fair value of RSUs vested was: •$22 million in 2023, •$22 million in 2022 and •$25 million in 2021. Nonvested RSUs accrue dividends that are paid out when RSUs vest. Any RSUs forfeited will not receive dividends. As RSUs vest, a portion of the shares awarded is withheld to cover employee taxes. As a result, the number of stock units vested and the number of common shares issued will differ. PERFORMANCE SHARE UNITS Through the 2022 Plan, we award PSUs — grants that entitle the holder to shares of our stock as the award vests. The Details The final number of shares granted in 2023, 2022 and 2021 will vest between a range of 0 percent to 150 percent of each grant’s target, depending upon actual company total shareholder return (TSR) compared against the TSR of an industry peer group. TSR assumes full reinvestment of dividends. The vesting provisions for PSUs granted in 2023, 2022 and 2021 were generally as follows: •awards granted in 2021 vest 100 percent on the third anniversary of the grant date, and awards granted in 2022 and in 2023 vest on March 1st following the end of the performance period, in each case as long as the individual remains employed by the company; •in the event of death or disability while employed, awards continue to be earned and settled based on actual company performance; WEYERHAEUSER COMPANY > 2023 ANNUAL REPORT AND FORM 10-K 83 •upon retirement at an age of at least 62, awards continue to vest in accordance with the vesting terms of the award, but a portion of the award is forfeited if retirement occurs before the one-year anniversary of the grant; •awards continue vesting for one year in the event of involuntary termination due to job elimination and the second anniversary of the grant date has passed; •in the case of a change of control during the performance period, awards are deemed earned at target performance and (i) vest as of the change of control date if the successor company does not assume the award or (ii) if assumed, vest upon termination of employment if, within two years of the effective date of the change in control, the recipient is involuntarily terminated other than for cause or leaves for good reason (as defined in the award terms and conditions); •awards will be forfeited upon termination of employment in all other situations including early retirement prior to age 62 and •awards vest at a maximum of 100 percent of target value in the event of negative absolute company TSR. Our Accounting Since the awards contain a market condition, the effect of the market condition is reflected in the grant-date fair value which is estimated using a Monte Carlo simulation model. This model estimates the TSR ranking of the company over the performance period. Compensation expense is based on the estimated probable number of earned awards and recognized over the vesting period on an accelerated basis. Generally, compensation expense would not be reversed if the market condition is not achieved, provided the requisite service period has been completed.

The total grant-date fair value of PSUs vested was: •$8 million in 2023, •$12 million in 2022 and •$8 million in 2021. Nonvested PSUs accrue dividends that are paid out when PSUs vest. Any PSUs forfeited will not receive dividends. As PSUs vest, a portion of the shares awarded is withheld to cover participant taxes. As a result, the number of share units vested and the number of common shares issued will differ. UNRECOGNIZED SHARE-BASED COMPENSATION As of December 31, 2023, our unrecognized share-based compensation cost for all types of share-based awards included $53 million related to non-vested equity-classified share-based compensation arrangements. These are expected to be recognized over a weighted average period of approximately 2.1 years. DEFERRED COMPENSATION STOCK EQUIVALENT UNITS Certain employees and our board of directors may defer compensation into stock equivalent units. The Details Eligible employees: •may choose to defer all or part of their bonus into stock equivalent units; •may choose to defer part of their salary, except for executive officers and •receive a 15 percent premium if the deferral is for at least five years. Our directors: •receive a portion of their annual retainer fee in the form of RSUs, which vest over one year and may be deferred into stock equivalent units; •may choose to defer some or all of the remainder of their annual retainer fee into stock equivalent units and •do not receive a premium for their deferrals. Employees and directors also choose when the deferrals will be paid out, although no deferrals may be paid until after the separation from service of the employee or director. Our Accounting We settle all deferred compensation accounts in cash for our employees. Our directors receive shares of common stock as payment for stock equivalent units, except that any directors who are subject to federal or provincial taxation in Canada have the choice to receive a cash amount equal to the fair market value of the company’s common stock on the date of payment. In addition, we credit all stock equivalent accounts with dividend equivalents. The number of common shares to be issued in the future to directors is 514 thousand as of December 31, 2023.

NOTE 16: LEASES The majority of our operating leases are related to our office and warehouse space, and the majority of our financing leases are related to vehicles and forklifts. Our leases have remaining lease terms of approximately 1 year to 25 years. Options to renew, extend or terminate a lease are reflected in our lease terms when we believe it is reasonably certain we will exercise that option. When our leases do not provide an implicit or an explicit interest rate, we use our incremental borrowing rate in determining the present value of lease payments.

Disclosure controls are controls and other procedures that are designed to ensure that information required to be disclosed in the reports filed or submitted under the Securities Exchange Act of 1934, as amended (Act), is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s (SEC) rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, to allow timely decisions regarding required disclosure. Based on their evaluation, the company’s principal executive officer and principal financial officer have concluded that the company’s disclosure controls and procedures are effective to ensure that information required to be disclosed complies with the SEC’s rules and forms. No changes occurred in the company’s internal control over financial reporting during the period that have materially affected, or are reasonably likely to materially affect, the company’s internal control over financial reporting. MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING Management is responsible for establishing and maintaining adequate internal control over financial reporting as is defined in the Securities Exchange Act of 1934 rules. Management, under our supervision, conducted an evaluation of the effectiveness of the company’s internal control over financial reporting based on the framework in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on our evaluation under the framework in Internal Control — Integrated Framework (2013), management concluded that the company’s internal control over financial reporting was effective as of December 31, 2023. The effectiveness of the company’s internal control over financial reporting as of December 31, 2023, has been audited by KPMG LLP, an independent registered public accounting firm, as stated in their report, which is included herein. WEYERHAEUSER COMPANY > 2023 ANNUAL REPORT AND FORM 10-K 89 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Shareholders and Board of Directors Weyerhaeuser Company: Opinion on Internal Control Over Financial Reporting We have audited Weyerhaeuser Company and subsidiaries’ (the Company) internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2023 and 2022, the related consolidated statements of operations, comprehensive income, cash flows, and changes in equity for each of the years in the three-year period ended December 31, 2023, and the related notes (collectively, the consolidated financial statements), and our report dated February 16, 2024 expressed an unqualified opinion on those consolidated financial statements. Basis for Opinion The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. Definition and Limitations of Internal Control Over Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. /s/ KPMG LLP Seattle, Washington February 16, 2024 90 OTHER INFORMATION RULE 10B5-1 TRADING ARRANGEMENTS During fourth quarter 2023, no “director” or “officer” (as defined in Rule 16a-1(f) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) of the company adopted, modified or terminated trading plans intended to satisfy the affirmative defense conditions of Rule 10b5-1(c) of the Exchange Act.
