Verification Statement Basis of Reporting

Activities, value chain and other business relationships HNI Corporation is a provider of workplace furnishings and residential building products, which are its two reportable segments.

Workplace furnishings include furniture systems, seating, storage, tables, architectural products, ancillary products, and hospitality products. These products are sold primarily through a national system of independent dealers, office product distributors, eCommerce retailers, and wholesalers, but also directly to end-user customers and federal, state, and local governments. Residential building products include a full array of gas, wood, electric, and pellet-fueled fireplaces, inserts, stoves, facings, outdoor fire pits and fire tables, and accessories. These products are sold through a national system of independent dealers and distributors, as well as Corporation-owned installing distribution and retail outlets.

The workplace furnishings market consists of two primary channels-the contract channel and the small and medium-sized business ("SMB") channel. End users across both channels represent a mix of commercial, health care, government, and education customers. While the Corporation primarily competes in the United States, it also distributes products to other countries in regions throughout the globe including North America, Europe, the Middle East, Africa, and Asia Pacific.

The Corporation also competes in the residential building products industry, where it is the North American market leader in hearth products. Hearth products are typically purchased by builders during the construction of new homes and homeowners during the renovation of existing homes. Distribution is primarily etfected through independent and company-owned installing distributors and retail outlets.

The Corporation purchases raw materials, components, and finished goods from a variety of suppliers, most of which are generally available from multiple sources. Major raw materials and components include steel, aluminum, zinc, lumber, veneer, particleboard, textiles, paint, hardware, glass, plastic products, packaging, foam, and fiberglass.

Approach to stakeholder engagement HNI's stakeholders were identified as the groups that our business and actions can potentially impact in a significant way. HNI's stakeholder

groups include our members (employees), customers, dealer partners, suppliers and logistics partners, investors, peers, local organizations in our communities, the architectural and design community, general contractors, builders, policy makers, and trade associations.

Materiality Table

Collective bargaining agreements In 2025, HNI did not have any members represented by collective bargaining agreements.

Process to determine material topics HNI conducted a full materiality assessment in 2022 to identify our strongest environmental, social, and governance priorities across all

stakeholder groups. HNI reviews the materiality assessment annually to ensure it accurately reflects the most significant priorities across all topics and stakeholders.

The materiality assessment was performed using a third party for outreach to stakeholders including: customers, suppliers, members, industry groups, and leaders in the organization. The first phase of the assessment included direct engagement with key senior leaders to better understand management's perspective on the risks and opportunities that are most relevant and impactful to HNI's business success. In the second phase, the perspectives of several key stakeholder groups was analyzed through a combination of direct engagement, analysis of external reported data, and other research to determine the significance of specific environmental and social topics. Using findings from these phases, a thorough quantitative scoring system analysis was conducted to prioritize the topic areas that are most important to HNI's management, internal and external stakeholder perspectives, and ongoing business success. The list of topics was reviewed and approved by senior management.

Material topics, risks, and opportunities are reviewed quarterly through HNI's company-wide Enterprise Risk Management program. Topic areas and impacts are also continuously reviewed through monitoring of changes to ESG reporting frameworks and standards, engagement with investors, customers, and other stakeholders, the use of a third-party ESG supply chain risk assessment tool, and industry benchmarking data.

Policies to halt and reverse biodiversity loss HNI's Supplier and Service Provide Code of Conduct contains policies related to biodiversity loss. It is HNI's policy to avoid sourcing species

of wood materials that are CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora) listed or identified on the IUCN Red List (International Union for Conservation of Nature's Red List of Threatened Species) as endangered, critically endangered or extinct in the wild.

It is also HNI's policy to avoid using wood from forest areas where traditional or civil rights are violated; forest areas where high conservation values are threatened by management activities; wood from forests in which genetically modified trees are planted; wood that has been harvested illegally or wood harvested from areas which have been converted from natural forest to plantations or non-forest uses.

HNI Supplier Code of Conduct

Management of biodiversity impacts HNI has taken action to avoid and minimize negative impacts on biodiversity in our supply chain by sourcing wood from legal and sustainable sources that support biodiversity.

In 2009, we began offering Forest Stewardship Council® (FSC®) Certified US-based furniture products to customers. FSC uses the High Conservation Value (HCV) approach in their certification standards. A key part of HCVs is ensuring activity in forests does not have a negative impact on biodiversity.

As of 2025, HNI's Workplace Furnishings segment has achieved 100% of materials (by spend) assessed against this goal. Kimball International has achieved 57% of materials

(by spend) analyzed and continues to progress toward full evaluation through ongoing integration of material and chemical assessment processes. The Residential Building Products segment is prioritizing regulatory-driven chemical compliance, including PFAS restrictions and alignment with evolving EU chemical regulations. Beyond 2025, HNI is advancing its material and chemical management program with a focus on eliminating priority substances from manufactured products by 2032.

HNI has removed regulated per- and polyfluoroalkyl substances (PFAS) from all textiles and paints. In addition, the company is advancing a broader, enterprise-wide etfort to identify PFAS across all segments and product categories and systematically phase out these substances from components and materials where present.

To assess and manage risks associated with chemicals of concern, HNI is integrating a Material Restricted Substances List (MRSL) into its sourcing and product development processes. The MRSL aligns with the International Living Future Institute (ILFI) Red List and is used to guide material selection and supplier requirements.

HNI conducts product testing and modeling to verify compliance with applicable chemical regulations and internal standards. The company also partners with Iowa State University to perform advanced chemical analyses, including proactive testing for PFAS. In addition, HNI utilizes in-house technologies such as X-ray fluorescence (XRF) analyzers to assess the elemental composition of materials.

HNI's Workplace Furnishings and Kimball International products have achieved third-party certifications that support chemical transparency and material health, including SCS Indoor Advantage, BIFMA LEVEL®.

Management of material topics

Sustainability is managed through HNI's Safety and Sustainability Management System, which is based on our Conscious Operations and Responsible Environments (CORE) strategy and commitments to respecting people, reducing impacts, and redefining tomorrow. Kimball International facilities have achieved ISO 14001 certification, bringing 36% of our manufacturing facilities to this standard.

SDGs 11, 12, 13

HNI's Safety and Sustainability Management System includes our zero waste to landfill waste management strategy and program, with the goal of achieving zero waste to landfill for all manufacturing facilities by 2030. This program requires zero waste facilities to conduct waste stream audits, develop waste reduction and diversion plans within operations, and implement office waste recycling programs.

2025 Corporate Responsibility Progress Report | page 10

306-1

Waste generation and significant waste-related impacts

HNI's waste-related impacts are primarily from production-related activities and the downstream disposal of decommissioned products

by customers. Within our own operations, our largest waste streams include wood (56%), metal (20%), mixed waste (9%), cardboard (8%), and foundry sand (2%).

SDGs 11, 12, 13

306-2

Management of significant waste-related impacts

To support HNI's goal of zero waste to landfill at all manufacturing facilities by 2030, our internal teams have been leading waste audits and waste mapping etforts to understand how much waste is currently recycled or landfilled at each facility. We work with our supplier and waste hauling partners to track monthly totals and review those numbers monthly. Some of our facilities produce hazardous waste. The hauling and disposal of all hazardous waste is managed by a third party who follows all applicable regulatory requirements.

SDGs 11, 12, 13

To reduce the amount of waste produced in the manufacturing of our products, our internal teams work to identify opportunities to remove waste from processes internally, as well as upstream at our suppliers' facilities, and downstream for our customers through our Design for the Environment process. We also continue to identify opportunities for reuse, as well as identify partners to assist us with recycling any waste materials.

3-3 Management of material topics HNI manages supplier environmental impacts through our HNI Supplier and Service Provider Code of Conduct, which requires suppliers to treat its employees with fairness and respect while also providing a safe and healthy work environment. We require strategic direct material suppliers covering at least 80% of direct material spend to acknowledge compliance with this Code.

HNI assesses strategic suppliers using supplier scorecards that integrate factors such as quality, reliability, cost, and business relationship with third-party environmental, social, and governance assessments to provide comprehensive insights into supplier performance, risk, and sustainability etforts.

Based on assessment of vulnerability and risk, HNI prioritizes suppliers located in Asia, for which we have a targeted and robust corporate social responsibility auditing process run by a third party to ensure suppliers follow appropriate labor, safety, environmental, and other CSR requirements. The program is based on SA8000 standards with additional EHS-related regulations. Audits are conducted on an annual basis.

HNI Supplier Code of Conduct

New suppliers that were screened using environmental criteria All new and existing suppliers must comply with our Code of Conduct.

Negative environmental impacts in the supply chain and actions taken In 2024, HNI incorporated third-party environmental, social, and governance assessments into our supplier scorecard process, and in 2025,

we assessed over 180 suppliers for negative impacts. The results of these assessments are used to facilitate discussions in quarterly business reviews with suppliers and enable collaboration toward improvement.

In 2025, HNI conducted onsite audits of 21 Asia-based suppliers across China, Vietnam, Malaysia, and Taiwan, representing over 51% of HNI's Asia-based strategic suppliers. No suppliers were identified with significant actual negative social impacts. Nine suppliers were flagged for potential negative environmental impacts. Potential negative environmental impacts identified during the assessments were limited to routine compliance observations related to:

Hazardous waste management practices

Completion of GHG inventories to support emission reduction planning

Verification of required EIA approvals

Since no significant actual impacts were identified, remediation of environmental impacts was not required and no supplier relationships were terminated as a result of the 2025 assessments. For suppliers with potential impacts, 100% developed and implemented corrective action plans (CAPs) to remediate identified issues and strengthen their environmental performance.
