This is Metsä Board

We focus on premium fresh fibre paperboards and are a forerunner in sustainability. Our strategy is to grow in fibre-based packaging materials and renew our industrial operations.

Focus on sustainable fresh fibre paperboards

A forerunner in sustainability Our products support the circular economy and they have a smaller carbon footprint compared to many other packaging mate- rials. Our future growth is based on more efficient use of resources and raw materials. Our target is fossil free production and products by the end of 2030.

We focus on premium and recyclable fresh fibre paperboards, that help our customers reduce their plastic use. Our paper- boards are mainly used in consumer packaging and in retail packaging solutions where demand is rather stable, regardless of the economic situation.

Strong position in a growing market

Investing in sustainable growth

We are a leading producer of folding boxboard and white kraftliners in Europe, and globally the biggest producer of coated white kraftliners. In the USA, we are the largest supplier of folding boxboard. We expect the global demand for paperboards to grow faster, at an annual rate of around 5%, compared to other packaging materials.

Our ongoing and planned investments respond to the growing demand for sustainable packaging materials. We are continuously modernising our industrial operations to further strengthen our competitiveness. We have a clear road map to implement our ambitious sustainability targets. This includes investments and explorations of alternative raw materials in cooperation with our partners.

We are part of the profitable Metsä Group and benefit from the good availability of our main raw material, northern wood. Our self-sufficiency in pulp guarantees the consistent and high quality of the fibre and enables the growth of our paperboard business.

METSÄ BOARD ANNUAL AND SUSTAINABILITY REPORT 2022

SUSTAINABILITY REPORT BUSINESS OPERATIONS AND VALUE CREATION Record result in a challenging business environment FINANCIAL DEVELOPMENT GOVERNANCE

We achieved an excellent result in 2022, and our financial position at the end of the year was strong. We continued our sustainability efforts to mitigate climate change and helped our customers lower their use of plastic and reduce the carbon footprint of their packages. All this builds a strong foundation for future growth, which we seek through our sustainable and profitable investments.

For Metsä Board, 2022 was an exceptional year in many ways. As a paperboard company, we achieved a record result in a challenging business environment that proved difficult to predict. Our sales were nearly EUR 2.5 billion, and our comparable operating result was EUR 521 million. At 20.9%, our return on capital employed exceeded our long-term target by a wide margin. Our result improved especially thanks to the higher prices of fresh fibre paperboards supported by a favourable currency effect. Success- ful price increases exceeded the rapid cost inflation. In addition, the profitability of Metsä Fibre, our associated company, was boosted by the higher market pulp prices. The past year was overshadowed by Russia’s war against Ukraine, which is continuing in 2023. In addition to human suffer- ing, Russia’s military operations triggered the most severe energy crisis in Europe’s recent history, making energy self-sufficiency a significant competitive factor for many companies. Metsä Board’s energy self-sufficiency is at a high level, which offers stability to our operations. The new recovery boiler and turbine that started up at the Husum pulp mill in December, will increase the production of bioenergy and take us closer to our goal of entirely fossil free production by the end of 2030. Valuable recognition of our sustainability efforts During the year, we continued our long-term work to promote sustainability. For the second year in a row, we secured a place on the ’A’ List in all of CDP’s three environmental focus areas: climate change mitigation, water security and forest protection. Only 12 out of 15,000 companies achieved the same excellent result. In EcoVadis’s evaluation, we were in the top 1% among paper, paperboard and packaging manufacturers, receiving full points in the environment section. These acknowledgements reflect our role as a forerunner in sustainability and the systematic work that

everyone at Metsä Board carries out to achieve our goals. Since 2022, the personal performance goals of all Metsä Board employ- ees have included at least one sustainability objective, which in my case concerns safety at work. Our strategy has proven its success Our strategy has proved its sustainability and success in a challenging market situation, and we will continue its systematic implementation – growing sustainably in fibre-based packaging materials. In recent years, we have strengthened our market position in premium fresh fibre paperboards and have met the quickly increasing demand for recyclable packaging materials that can replace plastic in our main markets – Europe and North America. In 2023, our paperboard capacity will increase following the completion of our investments in folding boxboard in Husum and kraftliner in Kemi. To continue our sustainable growth, we have launched pre-engineering for a new folding boxboard mill with an annual capacity of 800,000 tonnes in Kaskinen. A potential investment decision could be made in 2024 at the earliest.

Resource efficiency helps us reduce the environmental impact of packaging

Our resource-efficient paperboards made of renewable raw mate- rial have a smaller carbon footprint than many other packaging materials, and they are an excellent match to circular economy needs. Packaging design carried out in cooperation with our customers helps us continuously reduce the amount of packaging material and waste. Resource and production efficiency play a key role in the pre-engineering for the new folding boxboard mill in Kaskinen. We aim for the world’s most resource-efficient paperboard mill, with

shareholder value. Metsä Board’s Board of Directors proposes that a dividend of EUR 0.58 per share be distributed for 2022. The proposal is in line with our dividend policy and reflects confidence in our future success. Our excellent performance in a volatile operating environment is proof not only of a well-functioning strategy but also of a compe- tent and motivated personnel. I wish to thank all our employees for their great work and all our customers and other partners for their good cooperation.

world-class competitiveness and a product concept that enables carbon footprint reduction. By utiliing the best available tech- nology, the consumption of raw materials, energy and water per tonne of folding boxboard produced can be significantly reduced compared to our current production units. Strong financial position supports growth Our strong financial position creates a firm foundation for future and planned growth investments in fibre-based packaging materials.

Operating environment supports growing demand for fresh fibre paperboards • Population growth, urbanisation and rising living standards drive packaging • Global e-commerce continues to grow • Availability and quality of recycled fibre is declining • Regulation and consumer preferences favour fossil free packaging materials • The requirements of the circular economy become more specific and drive the development of the industry

We invest in sustainable and profitable growth

Metsä Board has significant investments under- way and in the pipeline to achieve sustainable growth in fibre-based packaging materials. In line with our strategy, we are also renewing our industrial operations to further strengthen our competitiveness. By using the best available technology, we improve our production and resource efficiency and reduce the carbon footprint of our products. We will increase the annual production capac- ity of folding boxboard at the Husum integrated mill by some 200,000 tonnes and of white kraftliners at the Kemi paperboard mill by some 40,000 tonnes. We expect both investments to be completed in the second half of 2023. The new recovery boiler and turbine of the Husum pulp mill started up at the end of 2022. This increased the mill’s bioenergy production and considerably improved the integrate’s energy self-sufficiency. In the renewal’s second phase, during the 2020s, an investment decision will be made concerning the renewal of the mill’s fibre line. The renewal will strengthen the Husum integrate’s role as an efficient and sustainable platform for the long-term development of paperboard production and is an important step towards our target of entirely fossil free mills. In the autumn of 2022, we initiated a pre-engineering process for the new Kaskinen paperboard mill, with an annual capacity of 800,000 tonnes. A potential investment decision will be made in 2024 at the earliest. The planning of the new mill is based on fossil free production, world-class resource and production efficiency, and a product concept that reduces carbon footprint.

Paperboard is the fastest growing packaging material

Paperboard demand is influenced by long-term trends

Paperboard accounts for around a third of the global packaging market, and it is expected to experience faster growth than other packaging materials – an average annual rate of 5%. The main growth drivers include the consumers’ increasing environmental awareness, which favours recyclable packages, and the ease of packaged food in daily life.

REGULATION Regulation seeks to reduce the negative impacts of climate change, the increasing amount of waste and loss of biodiversity.

The value of the global packaging market is around USD 1 billion Annual growth is approximately 4% (2021–2026).

EASE To make everyday life easier, consumers shop online and buy ready meals.

Consumers prefer recyclable packaging, policymakers drive reusability According to Euromonitor, 66% of consumers try to have a positive impact on the environment through their everyday actions. Reducing plastic is the top measure taken, followed by reducing food waste, recycling items, and using sustainable packaging. Recyclability is seen as the key sustainability feature for a sustaina- ble packaging. (source: Euromonitor International Global Lifestyles Survey 2022) With a recycling rate of 82%, paper packaging is the most recycled packaging material in the EU, while the plastic recycling rate is 38%. (Source: Eurostat) Reusability is favored in EU’ s waste hierarchy, although many third-party certified LCA studies show that reuse or refill is not always the best option for the climate and environment. The main purpose of packaging is to protect products, thereby preventing waste. Packaging accounts for only 5% of the total global food system greenhouse gas emissions. (Source: the UN and the EC)

Consumers responded to the inflationary environment of 2022 Rapid inflation has reduced consumers´ purchasing power and forced them to reconsider their consumption habits. The demand for packaged food has remained stable. Con- sumers have moved to less expensive products and private label products and are opting for discounters. Purchases of durables and luxury products are being postponed. Despite the pressure to save, the majority of consumers are eager to catch up on experiences they missed out during the pandemic.

Pulp market

Megatrends drive long-term demand for sustainably produced pulp

Globally, about 181 million tonnes of pulp made from fresh fibre is used each year, of which 112 million tonnes is pre-integrated into e.g. paper or board production. The remainder, 69 million tonnes, is sold to the market, and consists mainly of bleached softwood and hardwood pulp. Demand and prices for pulp can vary from year to year and are influenced, among others, by the general economic situation. In the long term, megatrends such as urbanisation and emerging economies will support demand for sustainably produced pulp. Demand growth will be sustained by the development of tissue and packaging board products. Also new products, such as pulp-based textile fibres will play an increasingly important role in the future. Market pulp supply has been limited in recent years by logistical bottlenecks and a number of planned and unplanned production stoppages.

SUSTAINABILITY REPORT BUSINESS OPERATIONS AND VALUE CREATION Our R&D aims for recyclability and resource efficiency FINANCIAL DEVELOPMENT GOVERNANCE

Promoting the goals of the circular economy drives the development of packaging materials throughout the packaging sector’s value chain. The requirements for packages are increasing, and cooperation among all the value chain operators is important.

We continue to focus on lightweighting of paperboard and developing recyclable protective barrier coatings for use in food packaging. Our competence in lightweighting of paperboards plays a key role in the pre-engineering of the Kaskinen folding boxboard mill, launched in 2022, which builds on fossil free production and significantly lower consumption of wood, energy and water per tonne of folding boxboard produced, compared to current produc- tion units. We aim for world-class resource efficiency and a product that enables the reduction of the carbon footprint. We are developing the resource efficiency of all our mills and make use of artificial intelligence. For example, at the Äänekoski paperboard mill, we can now locate the reason for process disrup- tions much faster thanks to new AI technology. The technology analyses the underlying causes of visual defects detected by AI based machine vision and looks for deviations among the 10,000 variables measured at the mill, also accounting for process delays. This helps target the right corrective measures more quickly, reducing the time lost due to disruptions. In the biobarrier programme launched in 2021, we continued to study new alternative products for reducing plastic. Several

Metsä Board has been an active participant in the 4evergreen alliance, covering the entire packaging value chain, since its establishment. The goal of 4evergreen is to make all fibre-based packaging recyclable by 2025 and raise the recycling rate in the EU from the current 82% to 90% by 2030. In 2022, 4evergreen published packaging design guidelines, as well as instructions for collecting and sorting fibre-based packaging and for assessing the recyclability of packaging. They support the recycling of fibre- based packaging and promote the competitiveness of fibre-based packaging against other packaging materials.

Aiming for world-class resource efficiency and a reduced carbon footprint

Ensuring and developing the recyclability and compostability of paperboards is one of the key goals of our product development process. In the fibre-based packaging material circular economy, our task is to provide the market with premium fresh fibre paperboards as resource-efficiently as possible, help replace fos- sil-based materials and reduce the carbon footprint of packaging.

Metsä Group’s 3D fibre product has been produced at Metsä Group’s and Valmet’s demo plant in Äänekoski since May 2022. Using brand new technology, the products are pressed from wood fibre into their final form and their properties can be tailored during the production process according to the intended purpose. Ready-to-use three-dimensional Muoto products are suitable for such applications as food packaging. If the market interest and product viability can be proved on a large scale, Metsä Group will consider building a larger production unit.

impacts of different materials, and with concrete packaging solu- tions for improving recyclability and material efficiency. In 2022, we organised 45 packaging development workshops at our Excellence Centre in Äänekoski. Metsä Group and Fortum’s ExpandFibre programme promoting the circular bioeconomy continued in 2022. Among other things, the programme focused on organising cooperation with packaging design companies and packaging technology companies and developing solutions to packaging challenges identified in develop- ment workshops. One example of these efforts was the moderni- sation of the pastry packaging used by bakeries, with Viipurilainen Kotileipomo as the pilot company. The packaging was developed with usability, ecology and layout in mind. The result was a pastry package that is easy to assemble, and that reduces the need for material by 25% and carbon dioxide emissions by roughly 34%.

potential products are being tested in the laboratory, and some proceeded to production testing last year. In accordance with our product development process, the prerequisites for sales and production will first be determined before making decisions about commercialisation. In 2022, we established a systematic development programme for reducing the use of all fossil-based raw materials. As part of this, we work with suppliers to find ways to reduce the carbon footprint of the raw materials we purchase. We have set as our goal that by the end of 2030, all the solutions and polymers developed for paperboards will be based on fossil free raw materials. Deeper customer cooperation We used our 360 Services to further strengthen our customer relationships. The services cover five areas: Sustainability Service; Packaging Design Service; Technical Service; R&D Service; and the Supply Chain and Digital Service. We helped our customers, for example, with life-cycle assess- ments of packaging, data-based comparisons of the environmental

E S G

At Metsä Board, sustainability is based on compliance with good corporate governance, bearing social and environmental responsibility, respecting business ethics and human rights, as well as the continuous improvement of operations with respect to all of the above. In addition to our own operations, we also expect sustainability from our suppliers, customers and other partners.

Sustainability governance model At Metsä Board, the realisation of sustainability is monitored and supported by the company’s Board of Directors, CEO and Corporate Management Team. Sustainability is incorporated in the company’s strategy, long-term business and investment plans, risk assessments and annual action plans approved by the Board of Directors. The CEO is responsible for the implementation of the sustaina- bility measures per instructions provided by the Board. In accord- ance with the annual plan, the CEO presents to the Board a review of environmental matters and a sustainability review focusing on the progress towards sustainability targets twice a year, as well as the reviews of work safety and R&D once a year. The company’s Corporate Management Team prepares sustainability-related matters before the CEO presents them to the Board. The Board discusses and approves the sustainability matters presented by the CEO, including the sustainability targets and related investment plans, and monitors their implementation annually.

Of the members of the Corporate Management Team, the Senior Vice President, Development, is responsible for research, product and business development, and sustainability. The SVP, Development, participates in Metsä Group’s Sustainability Process Management Team and reports on the realised results of the sustainability measures to the Sustainability Process Management Team quarterly. The CFO chairs Metsä Board’s Risk Committee, which deals with sustainability-related risks as part of the company’s general risk assessment. The results of the company’s risk assessment, includ- ing risks related to sustainability, are presented to the Board and the Audit Committee twice a year. In addition, the Audit Committee handles biannually an information security review and annully a compliance report. Other sustainability issues, such as investment plans, are also presented to the Board and the committees as appropriate.

Sustainability reporting is developing

When it enters into force, the new EU directive concerning sustainability reporting will have a major impact on corporate sustainability reporting. At Metsä Board, we have initiated preparations by adopting the ESG structure in our current sustainability report and by acquainting ourselves with the new reporting standards and verifying our key sustain- ability information. We have also adopted a reporting tool that enables the digital and machine-readable reporting of both financial and sustainability information. “There will be a stronger link between sustainability reporting and financial reporting. For example, Metsä Board reports on its climate impact, but it must also consider climate-related risks from a business perspective,” says Henri Sederholm , CFO.

The link between sustainability and remuneration The personal performance bonus target of each Metsä Board employee includes an ESG target. The CEO’s remuneration is based on Metsä Board’s operating result (weighting 50%) and the strategic targets defined by the Board of Directors (weighting 50%), including the sustainability targets, as well as the realisation of Metsä Group’s EBIT multiplier. In 2022, the CEO’s sustainability target was related to safety at work. The remuneration of the other members of the Corporate Management Team is based on Metsä Board’s operating result (weighting 30% or 50%), the targets of their respective areas of responsibility (weighting 50% or 70%), including the sustainability targets, as well as Metsä Group’s EBIT multiplier. In 2022, the sustainability targets of the other Corporate Management Team members related to the reduction of energy and water use, sustainability cooperation with customers, and the development of sustainable products, for example.

to the company’s SVP, Development, and presents topical sustain- ability matters to the entire Corporate Management Team on a regular basis. The Product Safety and Sustainability Director leads a team of experts, which works in close cooperation with produc- tion, wood supply, procurement and logistics, HR, marketing and sales, communications, investor relations and legal affairs. Wood supply, as well as sourcing and legal affairs, is centralised in Metsä Group. Sustainability is part of the entire personnel’s daily work. We also expect sustainability from our suppliers, customers and other partners. Further information on sustainability governance can be found on pages 52–57.
