GENERAL

Background

Mativ Holdings, Inc. is a global leader in specialty materials, solving our customers’ most complex challenges by engineering bold, innovative solutions that connect, protect, and purify our world. Mativ manufactures globally through our family of business-to-business and consumer product brands. Mativ targets premium applications across diversified and growing end-markets, from filtration to healthcare to sustainable packaging and more. Our broad portfolio of technologies combines polymers, fibers, and resins to optimize the performance of our customers’ products across multiple stages of the value chain.

Mativ was incorporated in Delaware in 1995 as a wholly-owned subsidiary of Kimberly-Clark Corporation ("Kimberly-Clark"). On November 30, 1995, Kimberly-Clark transferred its tobacco-related paper and other paper products businesses conducted in the United States, France and Canada to the Company and distributed all of the outstanding shares of common stock of the Company to its stockholders (the "spin-off"). As a result, the Company became an independent public company. Over time, the Company diversified its portfolio through innovation efforts and a number of acquisitions to broaden its exposure to adjacent categories, such as filtration, specialty films, tapes, and healthcare.

On July 6, 2022, Schweitzer-Mauduit International, Inc. ("SWM") completed the merger transaction involving Neenah, Inc. ("Neenah"). A wholly-owned subsidiary of SWM merged with and into Neenah (the "Merger"), with Neenah surviving the Merger as a direct and wholly-owned subsidiary of SWM. Effective as of the closing date of the Merger, SWM changed its name to Mativ Holdings, Inc.

On November 30, 2023, the Company completed the sale of the Engineered Papers business ("EP business") to Evergreen Hill Enterprise Pte. Ltd. ("Evergreen Hill Enterprise"). With the sale of the EP business (the "EP Divestiture"), Mativ ceased participating in tobacco-based product markets.

Effective with the sale, the EP business is presented as a discontinued operation for all periods presented and certain prior period amounts have been retrospectively recasted to reflect these changes. The consolidated financial statements and the notes thereto, unless otherwise indicated, are on a continuing operations basis. Refer to Note 9. Discontinued Operations of the Notes to Consolidated Financial Statements for more information on the discontinued operation and transaction.

Mativ and its subsidiaries manufacture on three continents, conduct business in over 90 countries and operate 35 production locations worldwide. Our products are sold globally, though are most prevalent in North America and Europe with, to a lesser extent, Asia-Pacific and the rest of the world making up the remainder.

Our principal executive office is located at 100 Kimball Place, Suite 600, Alpharetta, Georgia 30009 and our telephone number is (770) 569-4229. Our stock is traded on the New York Stock Exchange ("NYSE") under the symbol "MATV."

Strategic Overview

As a specialty materials manufacturing company, Mativ’s primary processes consist of taking basic inputs, such as fibers, resins and chemicals, to create highly engineered media, such as nonwovens, films, specialty paper and netting. We then further process our media through coating, saturating, adhesive application and advanced converting processes to impart specific product attributes that are valued by our customers and customized to meet their unique needs.

Mativ’s long-term growth ambition is focused on enhancing its position as a global supplier of choice, driving performance by engineering unique, innovative solutions that connect, protect, and purify our world.

Fuel our customers’ successes. We target leading customers in specialized, growing segments of materials markets, and we create value for our customers by combining capabilities, technologies, and service platforms to produce tailored solutions that uniquely solve their most complex challenges. We have an agile supply chain and manufacturing base that enables us to efficiently produce customized offerings, often in smaller batches, that provide premium quality and unique attributes. We also stretch across layers of the value chain, combining our technologies to provided added value to our products and a more complete solution. Further, our products are specified and often undergo rigorous qualification cycles, and we are sought out as a partner for innovation opportunities. This creates deep customer relationships, which we believe fuels our ability to grow in our categories. Examples of this include our ability to bundle multiple components (media, support, cores and tubes) for water filtration, our ability to extrude and coat our advanced films for specified attributes, our ability to create unique colors, textures and finishes for premium packaging and consumer applications, and our ability to modify release characteristics for various adhesive applications.

Capture accelerated growth potential powered by key trends and innovation. Our businesses are aligned with key macro trends and end markets with strong growth outlooks. In addition to our existing product lines, our team uses these long-term trends to guide innovation efforts and bring to life solutions that support our customers’ evolving needs. Key themes such as the demand for cleaner air and water, modern building practices, increased uses of adhesives, advancements in health and wellness and the desire for sustainable, eco-friendly alternatives, align with our offerings and provide long-term support for demand. In our filtration category, we produce multiple critical components of reverse osmosis filters supporting the increasing demand for clean water, as well as other highly engineered media to support rising needs for air and liquid purification in HVAC, industrial and life science applications. Our advanced films are used in automotive and building applications to safeguard surfaces from sunlight, sound, impact, water, and temperature—increasingly relevant to protect vehicles and buildings. Release liners are essential in the activation process of adhesives in both temporary and permanent connection applications, and are used in growing areas such as hygiene products for adult and feminine care, construction and labeling. Our healthcare lines support advanced healing, wound cleansing, skin-friendly adhesives, as well as device fixation for wearable medical devices—all influenced by an aging population and increased global focus on health and wellness. Our tapes and industrial products provide solutions used in growing areas such as cable harnesses and tape for electric vehicles, and protective coverings for cables used in infrastructure and construction. Lastly, our paper and packaging business addresses needs for sustainability and eco-friendly alternatives to plastic while supporting brand aesthetics and the customer experience.

Leverage economies of scale. We continue to capitalize on value creation opportunities created by the Merger. We have realized the majority of the previously announced $65.0 million of synergies expected from the transaction, and we are continuing to execute on plans for incremental value. These savings included selling, general and administrative reductions (including redundant public company costs), supply chain efficiencies (including procurement, logistics and operating optimization) and other cost reductions, such as purchase services and leased office consolidation. Further, we are executing on significant incremental revenue opportunities. We continue to identify strategic cross-selling opportunities and innovation in key categories like filtration, healthcare, release liners and tape. We also see geographic expansion as a growth opportunity to complement our expanded footprint in Asia, North America and Europe, demonstrated by recent growth investments in our sites in Italy, Canada, the United Kingdom and Mexico. Lastly, we are leveraging a more comprehensive value chain position, where we believe we can cross-source and present a more complete offerings to our customers.

Transform the portfolio. We focus our investments, resources and efforts towards categories with the highest value-creation potential, focused on growth and margin-accretive opportunities. We actively manage elements of our portfolio that are non-core, margin dilutive or do not align with our growth ambitions. We strategically divested our Engineered Papers business in November 2023 for $620.0 million in cash, subject to customary closing date adjustments, moving us away from tobacco-based product markets and freeing up resources to focus on more growth-oriented aspects of our portfolio. We also closed or divested a number of smaller, non-strategic sites. We have since redeployed capital to repay debt and invest in categories that are geographically expansive and products where we see additional opportunities for growth. We installed a new melt blown line in Germany that started in the first quarter of 2024, and we expect two extrusion lines to start up in late 2025, all in support of growth in transportation and water filtration. Further, we continue to onboard new business on our coater in Mexico that started in late 2023, which supports accelerated release liner growth in North and South America. We also expect a new hot-melt line in Italy to start up in late 2025 in support of accelerated growth in the automotive tape business for our electric vehicle and internal combustion engine platforms; and we are implementing a new athletic tape line in Canada to start up in early 2026 in support of the quickly growing athletic and sports tape business. Lastly, a new medical films line in the United Kingdom is scheduled to start up and begin customer qualification in Q1 of 2025 to accommodate the growing demand trends in our medical films business.

Reduce complexity and optimize our business. We continue to focus on optimizing our business, and we believe this presents a meaningful opportunity to unlock value. Since the Merger, we have significantly enhanced our portfolio mix and continue to prioritize debt reduction, reducing net debt by approximately 35%. We have also right sized our dividend to align with our current portfolio. We enacted an organizational realignment initiative (the "Plan") which enabled $20.0 million of run-rate savings at the end of 2024. The Company expects future initiatives under the Plan to include system integrations, further restructuring and transactional efficiencies, resulting in an additional $20.0 million in overhead cost reduction by the end of 2026. We have made investments in technology, consolidating ERP systems by 30% and streamlining our support processes. We optimized our manufacturing footprint from 48 manufacturing facilities at the time of the Merger to 35 manufacturing facilities today (a reduction of over 20%), divesting and/or consolidating non-core facilities and product lines, and we reduced the number of warehouses by 25%. We continue to evaluate our manufacturing footprint and non-core business lines for further opportunities to reduce complexity and unlock value.

We employ approximately 130 R&D employees in research and laboratory facilities around the world. We are known for our expertise in combining polymers, fibers and resins to create engineered solutions that optimize product performance and address the high standard requirement in healthcare, filtration and protective applications. We believe our research and development capabilities have played a key role in establishing our reputation for high quality, superior products and for reinforcing long standing customer relationships.

Sustainability focus and new eco-friendly initiatives. We believe that building long-term value for our customers and stakeholders requires a focus on sustainability that is also good for our business and communities. Our diverse product portfolio includes items that make water and air cleaner and safer, products that reduce energy consumption and support electrification, and items that are made from natural and sustainable fibers. We believe our sustainability focus better positions us to capitalize on the growing demand for eco-friendly products. We have also taken a number of steps in support of sustainability initiatives in our manufacturing processes, and we publish our progress in our company sustainability report. Several of our facilities are ISO-certified for environmental management systems and/or energy management standards. All unprocessed wood pulp is sourced exclusively from suppliers maintaining FSC and/or PEFC Chain of Custody certification. Our facilities also recycle and, whenever possible, reintroduce waste material into the manufacturing process to create new products. We continue to look for ways to enhance the sustainability of our business and make a positive impact on the communities in which we live and serve.

Raw Materials and Energy

We use a variety of resins, polymers, and synthetic fibers in our products. We source a variety of commodity-grade resins, including polypropylene and polyethylene, as well as more specialized materials such as thermoplastic polyurethane. Resin prices can fluctuate significantly and can impact profitability. Commodity grade resin prices can sometimes correlate with crude oil prices while specialty resin prices often do not. We also source synthetic fibers such as polyester, and commodity-grade wood pulp and specialty pulps, such as mercerized and flash dried pulp.

We have multiple sources for most of our raw material needs. For more commoditized inputs, the loss of a single supplier would not likely have a material adverse effect on our ability to procure needed raw materials from other suppliers. However, some of our specialty inputs are supplied by fewer manufacturers and our results could be more materially affected by the loss or disruption of supply of certain specialty resins, mercerized pulp or synthetic fibers from those producers.

Paper production uses significant amounts of energy, primarily electricity and natural gas. We believe that energy supply is generally reliable throughout our manufacturing footprint, although prices can fluctuate significantly based on demand. We enter into agreements to procure a portion of our energy requirements for future periods to reduce the uncertainty of future energy costs.

The majority of our energy requirements relate to natural gas and electricity in the U.S., and Europe. We consider these to be a relatively stable energy sources historically; however, the recent geopolitical events in various geographies in Europe and Asia have resulted in more volatile energy prices in Europe.

Additional information regarding agreements for the supply of certain raw materials and energy is included in Note 19. Commitments and Contingencies, of the Notes to Consolidated Financial Statements.

Research and Development

As of December 31, 2024, we employ approximately 130 research and development employees in research and laboratory facilities around the world. We are dedicated to developing product innovations and continuous improvements to meet the evolving needs of our customers. We believe our research and product development capabilities have played an important role in establishing our reputation for high quality, superior products.

Beyond prioritizing customer needs and business objectives, we aim to create products that deliver enduring value without compromising the health of our environment. Examples include DigiScape® Wallcovering, a durable, latex-saturated print media designed to offer a sustainable and safer alternative to traditional polyvinyl chloride (PVC) wall coverings, CONVERD® Wide Format Rigid Board, a fully recyclable, paper-based alternative for structural signage, Itasa Futura Liners, which integrate recycled base papers and low-impact manufacturing practices to minimize the environmental footprint of both our operations and products, NEENAH® Folding Board, which offers highly customizable and sustainable options for specialty packaging papers in various colors, textures, and coatings, and Recycotape TM, an innovative, sustainable tape backing designed for producing recyclable pressure-sensitive adhesive (PSA) tapes.

Responsible Sourcing: Mativ is dedicated to responsibly sourcing raw wood fiber materials, as outlined in our Sustainable Forestry Policy. This policy ensures that all wood fiber and pulp we purchase complies with local regulations, supports third-party sustainability certifications, namely FSC, and requires suppliers to meet our sustainability priorities and requirements. Since 2017, all pulp purchased within Mativ and our legacy businesses has met the FSC Mix, FSC Recycled, or FSC Controlled Wood standards, with a policy to only source wood pulp that meets at least the FSC Controlled Wood standard. Most of our fiber exceeds this minimum requirement. Additionally, all Mativ sites processing wood pulp hold FSC Chain of Custody certification. Beyond unprocessed wood fiber and pulp, some products in our Sustainable & Adhesive Solutions division include recycled post-consumer waste. Also, select Filtration & Advanced Materials products contain purchased recycled resin, where appropriate based on the product’s use phase.

Supply Chain Management: Our Supplier Code of Conduct sets the minimum standards that all Mativ suppliers must meet. We work with our suppliers to gather ESG-related information and conduct due diligence on identified social and environmental risks. Our approach to respecting and promoting human rights in our operations and across our value chain is also embodied in both our Code of Conduct and Supplier Code of Conduct and is guided by our Human Rights Policy. We expect our employees, suppliers, and business partners to uphold the principles of the Human Rights Policy, which are grounded in the UN Universal Declaration of Human Rights and ILO Conventions.

Social

Workforce Health and Safety: We prioritize the health and well-being of our employees and communities above all else, with a strong focus on ensuring physical, psychological, and emotional safety. Every Mativ facility implements a common set of Mativ safety tools and processes that are designed to detect critical hidden risk and work to eliminate or mitigate that risk, as well as maintain regulatory compliance. This commitment is reinforced through regular safety engagements with employees, various types of risk assessments, ongoing employee safety training, and the involvement of active joint health and safety teams. We have introduced Safety Key Element Maturity Assessments (SKEMA) to evaluate the maturity of our sites’ safety risk management practices against an ideal state. As a complement to SKEMA, we have refined our balanced scorecard to track ongoing safety performance against set targets, driving accountability and results. We have also launched a Safety Capital Risk Assessment Process and Capital Design Safety Review, enabling us to identify safety-focused capital projects across Mativ, prioritizing them based on their risk reduction potential.

Human Capital Management: As a global leader in specialty materials, our employees are our most important asset— generating ideas, engineering innovations, manufacturing leading products, and delivering services. Our strategy for providing a positive work experience for our employees is integrated into every stage of the employee lifecycle: attract, engage, grow, and reward:

•Attract: To build and diversify our talent pipeline, we employ a range of recruitment initiatives, including internship, apprenticeship, and rotational programs.

•Engage: We value and actively encourage employee feedback via quarterly town hall meetings hosted by our CEO, our “Getting To Know” webinar and podcast series hosted by alternating business leaders, and routine communications via email and within our intranet, known as Compass.

•Grow: Mativ’s MyPath performance and development framework provides resources to salaried employees to develop and grow their skillsets through targeted experiential learning and educational opportunities. Through MyPath, employees set individualized performance and development goals, complete regular check-in conversations with their managers, and leverage tools and resources to help them progress toward their career aspirations.

•Reward: We offer a suite of competitive benefits designed to help our employees and their families take charge of their health and well-being, including but not limited to medical, dental, and vision coverage, prescription drug plans, disability and life insurance, and family planning services, as well as up to 12 weeks of fully paid parental leave for salaried U.S.-based employees.

Our Communities: We believe that thriving businesses play a crucial role in building resilient communities, which is why we encourage our employees to actively support their communities through both local and company-wide initiatives. Whether by donating toys, participating in fun runs, mentoring, or supporting animal adoptions, Mativ employees are finding meaningful and creative ways to make a difference. To amplify these efforts, Mativ’s matching gift program matches employee contributions to qualified educational and charitable organizations.

Governance

Ethics and Integrity: Central to our cultural and operational foundation is the Mativ Code of Conduct, a key resource for making informed, compliant, and ethical decisions. This document details policies, standards, and expectations to guide every individual at Mativ in their work and interactions. The Code applies to all employees, officers, and directors of Mativ and its subsidiaries worldwide. Agents and contractors of the Company are also expected to read, understand, and abide by the Code. At the executive level, Mativ’s Chief Legal and Administrative Officer oversees our ethics program. At the Board level, the Audit Committee (AC) has been delegated responsibility for periodically reviewing the Company’s Code of Conduct and the Company’s systems to enforce and monitor compliance with the Code. The AC receives quarterly updates from management on ethics-related matters.

Data Security: Our Global Information Security Policy is a key component of our strategy to safeguard Mativ’s data and assets. This top-level policy, along with our detailed data management standards and procedures, guides users in

protecting the confidentiality, integrity, availability, and appropriate use of our data and assets. Our Chief Information Security Officer, who reports to the Chief Information Officer and ultimately to the Chief Executive Officer, oversees the Company’s data security program. Regular program status updates are provided to leadership through meetings of the Cybersecurity and IT Risk Steering Committee, Executive Leadership Team, AC, and full Board. We align our approach to data security management with the National Institute of Standards and Technology (NIST) framework. Our strategies to identify and mitigate data security risks include vulnerability scanning, internal audits, and annual external penetration testing. Mativ also engages in monthly data security awareness training and phishing simulations to reinforce a culture of integrity.

ESG Oversight: At the Board level, general oversight responsibility for ESG is delegated by the Board to the Nominating & Governance Committee (NGC). The NGC Chair reports on ESG-related matters to the full Board. Additionally, the AC oversees the risk management process through its supervision of our enterprise risk management (ERM) system, which provides a structured approach to identifying, assessing, monitoring, and managing risk, including ESG-related issues that may affect the short-term continuity or long-term viability of our business. Internal Audit conducts an annual ERM assessment and presents the findings to the AC. The AC Chair then reports any significant findings to the full Board. At the management level, our cross-functional ESG Committee includes representatives from each business segment’s EHS team, as well as from our corporate-level Sustainability, Human Resources, and Legal departments. Meeting monthly, the ESG Committee addresses key ESG issues relevant to our business and stakeholders and oversees the development and implementation of initiatives that advance our sustainability goals. The Committee is sponsored at the executive level by our Chief Legal and Administrative Officer, and the Deputy General Counsel & Assistant Corporate Secretary provides Committee updates at each regularly scheduled NGC meeting, with periodic reports to the full Board.

Working Capital

We normally maintain approximately 50 to 70 days of inventories to support our operations. Our sales terms average between 15 and 60 days for payment by our customers, dependent upon the products and market segment served. With respect to our accounts payable, we typically carry approximately 15 to 40 days outstanding, in accordance with our purchasing terms, which vary by business location. The accounts payable balance varies in relation to changes in our manufacturing operations, particularly due to changes in prices of wood pulp, resins and purchased energy and the level and timing of capital expenditures related to projects in progress.
