PART I

In this document, please note the following:

Due to rounding, numbers presented throughout this report may not add up precisely to totals we provide and percentages may not precisely reflect the absolute figures.

The Company

General

We operate in the pulp business and are among the largest publicly traded producers of market northern bleached softwood kraft, or “NBSK”, pulp in the world. Mercer Inc. reorganized as a company under the laws of the State of Washington in 2006 from a Washington business trust. Its common stock is quoted and listed for trading on the NASDAQ Global Market (MERC) and the Toronto Stock Exchange (MRI.U).

We are the sole NBSK producer, and the only significant producer of pulp for resale, known as “market pulp”, in Germany, which is the largest pulp import market in Europe. We also generate and sell a significant amount of surplus “green” energy to regional utilities. Our operations are located in Eastern Germany and Western Canada. We currently employ approximately 1,500 people. We operate three NBSK pulp mills with a consolidated annual production capacity of approximately 1.5 million ADMTs of NBSK pulp and 259 MW of electrical generation:

Organizational Chart

The following chart sets out our directly and indirectly owned principal operating subsidiaries, their jurisdictions of organization, their principal activities and their annual pulp production and electrical generation capacity:

History and Development of Business

We commenced pulp operations with the acquisition of our Rosenthal mill in 1994. In 1999, we completed a major capital project which, among other things, converted that mill to the production of kraft pulp from sulphite pulp, increased its annual production capacity and improved efficiencies. The aggregate cost of this project was approximately €361.0 million, of which approximately €102.0 million was financed through government grants. Subsequent capital investments and efficiency improvements have reduced emissions and energy costs and increased the Rosenthal mill’s annual production capacity to approximately 355,000 ADMTs.

In September 2004, we completed construction of the Stendal mill at an aggregate cost of approximately €1.0 billion. The Stendal mill is one of the largest NBSK pulp mills in Europe. The Stendal mill was financed through a combination of government grants totaling approximately €275.0 million, low-cost, long-term project debt which is largely severally guaranteed by the federal government and a state government in Germany, and equity contributions.

We currently have a 74.9% ownership interest in Stendal. We, and Stendal’s noncontrolling shareholder are parties to a shareholders’ agreement dated August 26, 2002, as amended, to govern our respective interests in Stendal. The agreement contains terms and conditions customary for these types of agreements, including restrictions on transfers of share capital and shareholder loans other than to affiliates, rights of first refusal on share and shareholder loan transfers, pre-emptive rights and piggyback rights on dispositions of our interest. The shareholders are not obligated to fund any further equity capital contributions to the project. The shareholders’ agreement provides that Stendal’s managing directors are appointed by holders of a simple majority of its share capital. Further, shareholder decisions, other than those mandated by law or for the provision of financial assistance to a shareholder, are determined by a simple majority of Stendal’s share capital.

In 2012, our Stendal mill commenced an approximate €40.0 million project, referred to as “Project Blue Mill”, which is designed to increase production and efficiency through debottlenecking initiatives including the installation of an additional 40 MW steam turbine at our Stendal mill. The debottlenecking which, among other things, requires the new turbine in order to enhance and efficiently utilize steam production, is designed to increase the mill’s annual pulp production capacity by 30,000 ADMTs. The new turbine is also expected to

initially produce an additional 109,000 MWh of surplus renewable energy for sale at premium pricing. Project Blue Mill is currently expected to be completed and start to generate power resources in or about September 2013.

A significant portion of the capital investments at our German mills, including the construction of the Stendal mill, were financed through government grants. Since 1999, our German mills have benefited from an aggregate €386.3 million in government grants. These grants reduce the cost basis of the assets purchased when the grants are received and are not reported in our income.

In February 2005, we acquired the Celgar mill for $210.0 million plus $16.0 million for the defined working capital of the mill. The Celgar mill was completely rebuilt in the early 1990s through a C$850.0 million modernization and expansion project, which transformed it into a modern and competitive producer.

Since its acquisition, we have effected several capital projects and other initiatives at the Celgar mill to increase its annual pulp production capacity to 520,000 ADMTs and its production of “green” energy. This includes a capital project, referred to as the “Celgar Energy Project”, which was completed in September 2010 and increased the Celgar mill’s production of “green” energy and optimized its power generation capacity, at an aggregate cost of approximately C$64.9 million, of which approximately C$48.0 million was financed by grants from the Canadian federal government.

The Pulp Industry

General

Pulp is used in the production of paper, tissues and paper-related products. Pulp is generally classified according to fiber type, the process used in its production and the degree to which it is bleached. Kraft pulp, a type of chemical pulp, is produced through a sulphate chemical process in which lignin, the component of wood which binds individual fibers, is dissolved in a chemical reaction. Chemically prepared pulp allows the wood’s fiber to retain its length and flexibility, resulting in stronger paper products. Kraft pulp can be bleached to increase its brightness. Kraft pulp is noted for its strength, brightness and absorption properties and is used to produce a variety of products, including lightweight publication grades of paper, tissues and paper-related products.

There are two main types of bleached kraft pulp, being softwood kraft made from coniferous trees and hardwood kraft made from deciduous trees. Softwood species generally have long, flexible fibers which add strength to paper while fibers from species of hardwood contain shorter fibers which lend bulk and opacity. Generally, prices for softwood pulp are higher than for hardwood pulp.

We produce and sell NBSK pulp, which is a bleached kraft pulp manufactured using species of northern softwood and is considered a premium grade because of its strength. It generally obtains the highest price relative to other kraft pulps. Southern bleached softwood kraft pulp is kraft pulp manufactured using southern softwood species and does not possess the strength found in NBSK pulp. NBSK pulp is the sole product of our mills.

Most paper users of market kraft pulp use a mix of softwood and hardwood grades to optimize production and product qualities. In 2012, market kraft pulp consumption was approximately 53% hardwood kraft, 45% softwood kraft and the remainder comprised of sulphite and unbleached pulp. Over the last several years, production of hardwood pulp, based on fast growing plantation fiber primarily from Asia and South America, has increased much more rapidly than that of softwood grades that have longer growth cycles. Hardwood kraft generally has a cost advantage over softwood kraft as a result of lower fiber costs, higher wood yields and, for newer hardwood mills, economies of scale. As a result of this growth in supply and lower costs, kraft pulp customers have substituted some of the pulp content in their products to hardwood pulp. Counteracting customers’ increased usage of hardwood pulp has been the requirement for strength characteristics in finished goods. Paper and tissue makers focus on larger paper machines with higher speeds and lower basis weights for certain papers which require the strength characteristics of softwood pulp. Additionally, where paper products are lightweight or specialized, like direct mail, magazine paper or premium tissue, or where strength or absorbency are important, softwood kraft forms a significant proportion of the fiber used. As a result, we believe that the ability of kraft pulp users to continue to further substitute hardwood for softwood pulp is limited by such requirements.

Table of Contents

Kraft pulp can be made in different grades, with varying technical specifications, for different end uses. High-quality kraft pulp is valued for its reinforcing role in mechanical printing papers, while other grades of kraft pulp are used to produce lower priced grades of paper, including tissues and paper-related products.

Markets

We believe that over 130 million ADMTs of chemical pulp are converted annually into printing and writing papers, tissues, carton boards and other white grades of paper and paperboard around the world. We also believe that over one third of this pulp is sold on the open market as market pulp, while the remainder is produced for internal purposes by integrated paper and paperboard manufacturers.

Demand for kraft pulp is cyclical in nature and is generally related to global and regional levels of economic activity. In 2008, overall global demand for all kraft pulp types, including softwood, was negatively impacted by the weak global economic conditions and global financial and credit turmoil the world began to experience in the second half of that year and which continued into the first half of 2009. Significant producer shutdowns and curtailments, along with strong demand from China, resulted in an improved supply-demand balance and improved prices in the second half of 2009 through 2010. Although global pulp markets continued to strengthen in the first half of 2011, mainly driven by demand from Asia, economic uncertainty in Europe and credit tightening in China resulted in a decrease in demand and weaker pulp prices in the fourth quarter of 2011. In 2012, there was continued economic uncertainty in Europe and credit tightening in China in the first half of the year. Further, in the latter part of 2012, weak demand for paper in Europe resulted in some integrated producers curtailing their paper production and selling their pulp on the market, primarily in China. These factors negatively impacted demand and supply of pulp and resulted in generally weak pulp prices.

Between 2003 and 2012, worldwide demand for chemical market pulp grew at an average rate of approximately 2.0% annually. The following chart illustrates the global demand for chemical market pulp for the periods indicated:

Estimated Global Chemical Market Pulp Demand

Since 2007, demand for softwood market pulp has grown in the emerging markets of Asia, Eastern Europe and Latin America. China in particular has experienced substantial growth and its imports of softwood market pulp grew by approximately 14% per annum between 2003 and 2012. China now accounts for approximately 26% of global bleached softwood kraft market pulp demand, compared to only 10% in 2003. Western Europe currently accounts for approximately 27% of global bleached softwood kraft market pulp demand, compared to approximately 38% in 2003.

The following chart sets forth industry-wide bleached softwood kraft delivery levels to China between 2003 to the present:

Growth in NBSK pulp demand in China and other emerging markets has, to a large extent, been driven by increased demand from tissue producers, as a result of economic growth and rising income levels and living standards in such markets. These factors generally contribute to a greater demand for personal hygiene products in such regions. In China alone, two large tissue producers have publicly announced plans to add a total of 50 tissue paper machines at various sites by the end of 2015 to increase their annual tissue capacity by approximately 2.3 million ADMTs. At this time there can be no assurance as to when and how much of such capacity expansion will be implemented.

This has also led to an overall shift in demand for NBSK pulp, as demand from tissue producers has increased, while demand from printing and writing end uses has decreased. Between 2003 and 2012, NBSK pulp demand for tissue production increased by approximately 106% which has more than offset the secular decline in demand in printing and writing papers resulting from the rapid growth of digital media.

The following chart compares NBSK pulp demand by end use in each of 2003 and 2012:

Table of Contents

A measure of demand for kraft pulp is the ratio obtained by dividing the worldwide demand of kraft pulp by the worldwide capacity for the production of kraft pulp, or the “demand/capacity ratio”. An increase in this ratio generally occurs when there is an increase in global and regional levels of economic activity. An increase in this ratio also generally indicates greater demand as consumption increases, which often results in rising kraft pulp prices and a reduction of inventories by producers and buyers. As prices continue to rise, producers continue to run at higher operating rates. However, an adverse change in global and regional levels of economic activity generally negatively affects demand for kraft pulp, often leading buyers to reduce their purchases and rely on existing pulp inventories. As a result, producers run at lower operating rates by taking downtime to limit the build-up of their own inventories. The demand/capacity ratio for softwood kraft pulp was approximately 93%, 92% and 93% in 2012, 2011 and 2010, respectively.

A significant factor affecting our market is the amount of closures of old, high-cost capacity. Over the last seven years, several mills in North America, Finland, Sweden and Africa were indefinitely closed. Although some capacity was restarted in late 2009 and 2010 in response to very high NBSK pulp prices, we believe the net effect of these closures and restarts is an estimated 3.4 million tonnes of capacity removed from the market since 2006. Further, in efforts to improve environmental and safety standards, China has publicly stated that it will be reducing existing pulp and paper capacity in the near term by closing “old” mills. At this time, there can be no certainty as to the amount and timing of any such closures.

We are aware of one new NBSK mill in Russia which is scheduled to start up in early 2013. When ramped up, the new mill is expected to provide a net incremental increase in annual pulp production capacity of approximately 490,000 ADMTs. Other than the foregoing, we are unaware of any new material NBSK pulp capacity that has been announced. We believe that the absence of other plant expansions is due in part to fiber supply constraints and high capital costs.

NBSK Pulp Pricing

Pulp prices are highly cyclical. In general, kraft pulp is a globally traded commodity. Pricing and demand are influenced by the balance between supply and demand, as affected by global macroeconomic conditions, changes in consumption and capacity, the level of customer and producer inventories and fluctuations in exchange rates. As Northern Europe has historically been the world’s largest market and NBSK is the premium grade, the European NBSK market pricing is generally used as a benchmark price by the industry.

The average annual European list prices for NBSK pulp since 2000 have ranged from a low of approximately $447 per ADMT to a high of $1,030 per ADMT.

Table of Contents

The following chart sets out the changes in list prices for NBSK pulp in Europe, as stated in U.S. dollars, Canadian dollars and Euros for the periods indicated:

Source: RISI pricing report.

In 2006, pulp prices increased steadily from approximately $600 per ADMT in Europe to $870 per ADMT at the end of 2007. These price increases resulted from increased demand and the closure of several pulp mills, particularly in North America, which reduced NBSK capacity. In the second half of 2008, list prices for NBSK pulp decreased markedly due to weak global economic conditions. As a result, list prices for NBSK pulp in Europe decreased from $900 per ADMT in mid-2008 to $635 per ADMT at the end of the year. Such pulp price weakness continued into early 2009, though commencing in mid-2009, pulp markets began to strengthen which led to improved prices. Strong demand from China, capacity closures and historically low global inventories for bleached softwood kraft pulp helped support upward price momentum. During the second half of 2009, several price increases raised European list prices by a total of $170 per ADMT to $800 per ADMT by year end. Such price increases were partially offset by the continued weakening of the U.S. dollar versus the Euro and Canadian dollar during the period.

In 2010, several increases lifted prices to record levels in the middle of the year and at the end of 2010 list prices were near historic highs of $950, $960 and $840 per ADMT in Europe, North America and China, respectively. Pulp prices remained strong in 2011, reaching record levels of $1,030 per ADMT in Europe and $1,035 and $920 per ADMT in North America and China, respectively. However, uncertainty concerning the economic situation in Europe, along with credit tightening in China in the last part of the year, caused pulp prices to drop to $825 per ADMT in Europe and $890 and $670 per ADMT in North America and China, respectively, by the end of the year. Economic uncertainty in Europe and China continued to dampen demand and NBSK pulp prices, which remained generally weak in 2012. Year-end list prices were approximately $810, $870 and $655 per ADMT in Europe, North America and China, respectively.

A producer’s net sales realizations are list prices, net of customer discounts, commissions and other selling concessions. While there are differences between NBSK list prices in Europe, North America and Asia, European prices are generally regarded as the global benchmark and pricing in other regions tends to follow European trends. The nature of the pricing structure in Asia is different in that, while quoted list prices tend to be lower than Europe, customer discounts and commissions tend to be lower resulting in net sales realizations that are generally similar to other markets.

Table of Contents

The majority of market NBSK pulp is produced and sold by Canadian and Northern European producers, while the price of NBSK pulp is generally quoted in U.S. dollars. As a result, NBSK pricing is affected by fluctuations in the currency exchange rates for the U.S. dollar versus the Canadian dollar, the Euro and local currencies. NBSK pulp price increases during 2006, 2007 and the first half of 2008 were in large part offset by the weakening of the U.S. dollar. Similarly, the strengthening of the U.S. dollar against the Canadian dollar and the Euro towards the end of 2008 helped partially offset pulp price decreases caused by the deterioration in global economic conditions. The overall strengthening of the U.S. dollar against the Euro in 2010, and in particular in the first half of 2010, improved the operating margins of our German mills. Although the U.S. dollar weakened against the Euro for most of 2011, it strengthened at the end of 2011. Overall, the U.S. dollar was 8% stronger against the Euro in 2012 compared to 2011, partially offsetting pulp price decreases in 2012.

The global supply and demand balance for NBSK pulp is a key determinant in pulp pricing. The following chart sets forth changes in FOEX PIX index prices for NBSK pulp and global bleached softwood kraft inventory levels between 2003 to 2012:

Competition

Pulp markets are large and highly competitive. Producers ranging from small independent manufacturers to large integrated companies produce pulp worldwide. Our pulp and customer services compete with similar products manufactured and distributed by others. While many factors influence our competitive position, particularly in weak economic times, a key factor is price. Other factors include service, quality and convenience of location. Some of our competitors are larger than we are in certain markets and have substantially greater financial resources. These resources may afford those competitors more purchasing power, increased financial flexibility, more capital resources for expansion and improvement and enable them to compete more effectively. Our key NBSK pulp competitors are principally located in Northern Europe and Canada.

The Manufacturing Process

The following diagram provides a simplified description of the kraft pulp manufacturing process at our pulp mills:

In order to transform wood chips into kraft pulp, wood chips undergo a multi-step process involving the following principal stages: chip screening, digesting, pulp washing, screening, bleaching and drying.

In the initial processing stage, wood chips are screened to remove oversized chips and sawdust and are conveyed to a pressurized digester where they are heated and cooked with chemicals. This occurs in a continuous process at the Celgar and Rosenthal mills and in a batch process at the Stendal mill. This process softens and eventually dissolves the phenolic material called lignin that binds the fibers to each other in the wood.

Cooked pulp flows out of the digester and is washed and screened to remove most of the residual spent chemicals and partially cooked wood chips. The pulp then undergoes a series of bleaching stages where the brightness of the pulp is gradually increased. Finally, the bleached pulp is sent to the pulp machine where it is dried to achieve a dryness level of more than 90%. The pulp is then ready to be baled for shipment to customers.

A significant feature of kraft pulping technology is the recovery system, whereby chemicals used in the cooking process are captured and extracted for re-use, which reduces chemical costs and improves environmental performance. During the cooking stage, dissolved organic wood materials and used chemicals, collectively known as black liquor, are extracted from the digester. After undergoing an evaporation process, black liquor is burned in a recovery boiler. The chemical compounds of the black liquor are collected from the recovery boiler and are reconstituted into cooking chemicals used in the digesting stage through additional processing in the recausticizing plant.

15

Table of Contents

The heat produced by the recovery boiler is used to generate high-pressure steam. Additional steam is generated by a power boiler through the combustion of biomass consisting of bark and other wood residuals from sawmills and our woodrooms and residue generated by the effluent treatment system. Additionally, during times of upset, we may use natural gas to generate steam. The steam produced by the recovery and power boilers is used to power a turbine generator to generate electricity, as well as to provide heat for the digesting and pulp drying processes.

Our Mills and Product

We manufacture and sell NBSK pulp produced from woodchips and pulp logs at our three mills.

The following table sets out our pulp production capacity and actual production by mill for the periods indicated:

Rosenthal Mill. The Rosenthal mill is situated on a 220 acre site in the town of Blankenstein in the state of Thüringia, approximately 300 kilometers south of Berlin. The Saale river flows through the site of the mill. In late 1999, we completed a major capital project which converted the Rosenthal mill to the production of kraft pulp. It is a single line mill with a current annual production capacity of approximately 355,000 ADMTs of kraft pulp. The mill is self-sufficient in steam and electrical power. Some excess electrical power which is constantly generated is sold to the regional power grid. The facilities at the mill include:

The kraft pulp produced at the Rosenthal mill is a long-fibered softwood pulp produced by a sulphate cooking process and manufactured primarily from wood chips and pulp logs. A number of factors beyond economic supply and demand have an impact on the market for chemical pulp, including requirements for pulp bleached without any chlorine compounds or without the use of chlorine gas. The Rosenthal mill has the capability of producing both “totally chlorine free” and “elemental chlorine free” pulp. Totally chlorine free pulp

16

Table of Contents

is bleached to a high brightness using oxygen, ozone and hydrogen peroxide as bleaching agents, whereas elemental chlorine free pulp is produced by substituting chlorine dioxide for chlorine gas in the bleaching process. This substitution virtually eliminates complex chloro-organic compounds from mill effluent.

Kraft pulp is valued for its reinforcing role in mechanical printing papers and is sought after by producers of paper for the publishing industry, primarily for magazines and advertising materials. Kraft pulp is also an important ingredient for tissue manufacturing, and tissue demand tends to increase with living standards in developing countries. Kraft pulp produced for reinforcement fibers is considered the highest grade of kraft pulp and generally obtains the highest price. The Rosenthal mill produces pulp for reinforcement fibers to the specifications of certain of our customers. We believe that a number of our customers consider us their supplier of choice.

Stendal Mill. The Stendal mill is situated on a 200 acre site owned by Stendal that is part of a larger 1,250 acre industrial park near the town of Stendal in the state of Saxony-Anhalt, approximately 300 kilometers north of the Rosenthal mill and 130 kilometers west of Berlin. The mill is adjacent to the Elbe river and has access to harbor facilities for water transportation. The mill is a single line mill with a current annual design production capacity of approximately 650,000 ADMTs of kraft pulp. The Stendal mill is self-sufficient in steam and electrical power. Some excess electrical power which is constantly being generated is sold to the regional power grid. The facilities at the mill include:

The kraft pulp produced at the Stendal mill is of a slightly different grade than the pulp produced at the Rosenthal mill as the mix of softwood fiber used is slightly different. This results in a complementary product more suitable for different end uses. The Stendal mill is capable of producing both totally chlorine free and elemental chlorine free pulp.

Celgar Mill. The Celgar mill is situated on a 400 acre site near the city of Castlegar, British Columbia. The mill is located on the south bank of the Columbia River, approximately 600 kilometers east of the port city of Vancouver, British Columbia, and approximately 32 kilometers north of the Canada-U.S. border. The city of Seattle, Washington is approximately 650 kilometers southwest of Castlegar. It is a single line mill with a current annual production capacity of approximately 520,000 ADMTs of kraft pulp. Internal power generating capacity resulting from the completion of the Celgar Energy Project in 2010 enables the Celgar mill to be self-sufficient in electrical power and to sell surplus electricity. The facilities at the Celgar mill include:

Table of Contents

The Celgar mill produces high-quality kraft pulp that is made from a unique blend of slow growing/long-fiber Western Canadian tree species. It is used in the manufacture of high-quality paper and tissue products. We believe the Celgar mill’s pulp is known for its excellent product characteristics, including tensile strength, wet strength and brightness. The Celgar mill is a long-established supplier to paper and tissue producers in Asia.

Generation and Sales of “Green” Energy and Chemicals at our Mills

Our pulp mills are large scale bio-refineries that, in addition to pulp, also produce surplus “carbon neutral” or “green” energy. As part of the pulp production process our mills generate “green” energy using carbon-neutral biofuels such as black liquor and wood waste. Through the incineration of biofuels in the recovery and power boilers, our mills produce sufficient steam to cover all of our steam requirements and allow us to produce surplus electricity which we sell to third party utilities. As a result, we have benefitted from “green” energy legislation, incentives and commercialization that has developed over the last few years in Europe and Canada. In addition, our Stendal mill also produces tall oil as a by-product of its production processes and sells the same in the market.

Our surplus energy sales provide our mills with a new stable revenue source unrelated to pulp prices. Since our energy production is a by-product of our pulp production process, there are minimal incremental costs and our surplus energy sales are highly profitable. We believe that this revenue source from power sales gives our mills a competitive advantage over other older mills which do not have the equipment or capacity to produce and/or sell surplus power in a meaningful amount.

In 2012 and 2011, we sold 710,241 MWh and 652,113 MWh of surplus energy, respectively, and recorded revenues of €60.6 million and €58.0 million, respectively, from such energy sales.

Such Act, in existence since 2000, requires that public electric utilities give priority to electricity produced from renewable energy sources by independent power producers and pay a fixed tariff for a period of 20 years. Under the program, our German mills now sell their surplus energy to the local electricity grid at the rates stipulated by the Renewable Energy Act for biomass energy.

Since 2005, our German mills have also benefited from the sale of emission allowances under the European Union Carbon Emissions Trading Scheme, referred to as “EU ETS”. However, our eligibility for special tariffs under the Renewable Energy Act has reduced the amount of emissions allowances granted to our German mills under the EU ETS.

In 2012, we commenced Project Blue Mill which is designed to increase the Stendal mill’s annual pulp production by 30,000 ADMTs and initially produce an additional 109,000 MWh of surplus renewable electricity. Project Blue Mill is eligible for €12.0 million of non-refundable government grants and the Stendal mill arranged a €17.0 million secured term debt facility, amortized over five-years, of which 80% will be government guaranteed. The balance of Project Blue Mill will be funded through operating cash flow of the Stendal mill and up to an aggregate of €6.5 million in pro rata shareholder loans from Mercer Inc. and its noncontrolling shareholder.

In 2012, we generated €11.6 million from the sale of tall oil, a by-product of our production process.

In 2012, our Rosenthal and Stendal mills sold approximately 169,613 MWh and 368,634 MWh of electricity, respectively, for proceeds of €15.1 million and €32.2 million, respectively.

Celgar Mill

In September 2010, we completed the Celgar Energy Project at the Celgar mill to increase and optimize the mill’s production of “green” energy. The project included the installation of a 48 MW condensing turbine, which brought the mill’s installed generating capacity up to 100 MW, and upgrades to the mill’s bark boiler and steam consuming facilities. The Celgar mill has an Electricity Purchase Agreement with British Columbia Hydro and

Table of Contents

Power Authority, referred to as “B.C. Hydro”, for the sale of power generated from such project. Under the Electricity Purchase Agreement, the Celgar mill agreed to supply a minimum of approximately 238,000 MWh of surplus electrical energy annually to the utility over a ten-year term. We financed the Celgar Energy Project principally with funding of approximately C$48.0 million of Canadian governmental grants.

In 2012, we sold roughly 171,994 MWh of surplus renewable electricity at our Celgar mill which generated approximately C$17.2 million in annual revenues.

Production Costs

Our major costs of production are fiber, labor, energy and chemicals. Fiber, comprised of wood chips and pulp logs, is our most significant operating expense. Given the significance of fiber to our total operating expenses and our limited ability to control its costs, compared with our other operating costs, volatility in fiber costs can materially affect our margins and results of operations.

Fiber

Our mills are situated in regions which generally provide a relatively stable supply of fiber. The fiber consumed by our mills consists of wood chips produced by sawmills as a by-product of the sawmill process and pulp logs. Wood chips are small pieces of wood used to make pulp and are either wood residuals from the sawmill process or logs or pulp logs chipped especially for this purpose. Pulp logs consist of lower quality logs not used in the production of lumber. Wood chips and pulp logs are cyclical in both price and supply.

Generally, the cost of wood chips and pulp logs is primarily affected by the supply and demand for lumber. Additionally, regional factors such as harvesting levels and weather conditions can also have a material effect on the supply, demand and price for fiber.

In Germany, since 2006, the price and supply of wood chips has been affected by increasing demand from alternative or renewable energy producers and government initiatives for carbon neutral energy. Declining energy prices and weakening economies in the first half of 2009 tempered the increased demand for wood chips that resulted from initiatives by European governments to promote the use of wood as a carbon neutral energy. Over the long-term, we expect this non-traditional demand for fiber to continue to increase.

In April 2008, the Russian government raised tariffs on the export of sawmill and pulp wood to 25% from 20%. A further increase to 80% was initially scheduled for January 1, 2009 but was officially deferred twice and Russia’s export tariff remained unchanged at 25% in 2011. In August 2012, Russia entered the World Trade Organization, or “WTO”, and, due to inclusion in the WTO, Russia has lowered its export tariffs to between 13% and 15%, which we believe has had a positive impact on the European fiber supply.

Offsetting some of the increases in demand for wood fiber have been initiatives in which we and other producers are participating to increase harvest levels in Germany, particularly from small private forest owners. We believe that Germany has the highest availability of softwood forests in Europe suitable for harvesting and manufacturing. We believe private ownership of such forests is approximately 50%. Many of these forest ownership stakes are very small and have been harvested at rates much lower than their rate of growth. In 2009, forest owners began to reduce their harvesting rates in response to slowing economies and weaker demand for pulp logs, leading to an undersupply which resulted in increased fiber prices during that year. Fiber prices continued to increase through most of 2010 and 2011, driven by a weak lumber market, lower harvesting in central Germany and increased demand for wood from the energy sector for heating and other bio-energy purposes.

In 2012, fiber prices in Germany decreased by approximately 10%, mainly due to reduced demand for fiber from the European particle board industry and other regional residual fiber users and the start of a recovery in lumber markets.

We believe we are the largest consumer of wood chips and pulp logs in Germany and often provide the best long-term economic outlet for the sale of wood chips in Eastern Germany. We coordinate the wood procurement activities for our German mills to reduce overall personnel and administrative costs, provide greater purchasing power and coordinate buying and trading activities. This coordination and integration of fiber flows also allows us to optimize transportation costs, and the species and fiber mix for both mills.

In 2012, the Rosenthal mill consumed approximately 1.7 million cubic meters of fiber. Approximately 63% of such consumption was in the form of sawmill wood chips and approximately 37% was in the form of pulp logs. The wood chips for the Rosenthal mill are sourced from approximately 27 sawmills located primarily in the states of Bavaria, Baden-Württemberg and Thüringia and are within a 300 kilometer radius of the Rosenthal mill. Within this radius, the Rosenthal mill is the largest consumer of wood chips. Given its location and size, the Rosenthal mill is often the best economic outlet for the sale of wood chips in the area. Approximately 75% of the fiber consumed by the Rosenthal mill is spruce and the remainder is pine. While fiber costs and supply are subject to cyclical changes largely in the sawmill industry, we expect that we will be able to continue to obtain an adequate supply of fiber on reasonably satisfactory terms for the Rosenthal mill due to its location and our long-term relationships with suppliers. We have not historically experienced any significant fiber supply interruptions at the Rosenthal mill.

Wood chips for the Rosenthal mill are normally sourced from sawmills under one year contracts with quarterly adjustments for market pricing. Substantially all of our chip supply is sourced from suppliers with which we have a long-standing relationship. Pulp logs are sourced from the state forest agencies in Thüringia, Saxony and Bavaria on a contract basis and partly from private holders on the same basis as wood chips. Like the wood chip supply arrangements, these contracts tend to be for one-year terms with quarterly adjustments for market pricing. We organize the transportation of pulp logs sourced from the state agencies in Thüringia, Saxony and Bavaria after discussions with the agencies regarding the quantities of pulp logs that we require.

In 2012, the Stendal mill consumed approximately 3.3 million cubic meters of fiber. Approximately 24% of such fiber was in the form of sawmill wood chips and approximately 76% in the form of pulp logs. The core wood supply region for the Stendal mill includes most of the Northern part of Germany within an approximate 300 kilometer radius of the mill. We also purchase wood chips from Southwestern and Southern Germany. The fiber base in the wood supply area for the Stendal mill consisted of approximately 66% pine and 34% spruce and other species in 2012. The Stendal mill has sufficient chipping capacity to fully operate solely using pulp logs, if required. We source pulp logs partly from private forest holders and partly from state forest agencies in Thüringia, Saxony-Anhalt, Mecklenburg-Western Pomerania, Saxony, Lower Saxony, North Rhine-Westphalia, Hesse and Brandenburg.

In 2012, the Celgar mill consumed approximately 2.6 million cubic meters of fiber. Approximately 69% of such fiber was in the form of sawmill wood chips and the remaining 31% came from pulp logs processed through its woodroom or chipped by a third party. The source of fiber at the mill is characterized by a mixture of species (whitewoods and cedar) and the mill sources fiber from a number of Canadian and U.S. suppliers.

As a result of the cyclical decline in sawmill chip supply resulting from lower lumber production in British Columbia commencing in 2008, the Celgar mill increased its U.S. purchases of fiber, diversified its suppliers and, where possible, increased chip production through third party field chipping contracts and existing sawmill suppliers. In 2009, the Celgar mill upgraded its woodroom which, along with subsequent improvements during the year, increased its capacity to be able to process up to 50% of the mill’s fiber needs. The woodroom upgrades also increased the mill’s ability to process small diameter logs and facilitate an efficient flow of fiber. This has increased the overall volume of fiber being processed and helped mitigate increases in the price of fiber.

The Celgar mill has access to approximately 25 different suppliers from Canada and the U.S., representing approximately 75% of its total annual fiber requirements. The Celgar mill’s woodroom supplied the remaining 25% of the mill’s fiber requirements in 2012. Chips are purchased in Canada and the U.S. in accordance with chip purchase agreements. Generally, pricing is reviewed and adjusted periodically to reflect market prices. One

of the longer-term contracts is a so-called “evergreen” agreement, where the contract remains in effect until one of the parties elects to terminate. Termination requires a minimum of two and, in some cases, five years’ written notice. All other contracts are generally for one year with quarterly adjustments or on three-month terms.

To secure the volume of pulp logs required by its woodroom, the Celgar mill has entered into pulp log supply agreements, which can range from three-month to one-year terms, with a number of different suppliers, many of whom are also contract chip suppliers to the mill. All of the pulp log agreements can be terminated by either party for any reason, upon seven days’ written notice.

In 2012, our fiber costs at the Celgar mill were approximately 6% higher than in 2011, as a result of the impact of foreign exchange changes more than offsetting improved availability of wood chips.

Labor

Our labor costs are generally steady, with small overall increases due to inflation in wages and health care costs. Over the last three years, we have been able to largely offset such increases by increasing our efficiencies and production and streamlining operations.

Energy

Our energy is primarily generated from renewable carbon neutral sources, such as black liquor and wood waste. Our mills produce all of our steam requirements and generate excess energy which we sell to third party utilities. In 2012, we generated 1,704,058 MWh and sold 710,241 MWh of surplus energy. See also “—Generation and Sales of ‘Green’ Energy and Chemicals at our Mills”. We utilize fossil fuels, such as natural gas, in limited circumstances primarily in our lime kilns and we use a limited amount for start-up and shutdown operations. Additionally, from time to time, mill process disruptions occur and we consume small quantities of purchased electricity and fossil fuels to maintain operations. As a result, all of our mills are subject to fluctuations in the prices for fossil fuels.

Chemicals

Our mills use certain chemicals which are generally available from several suppliers and sourcing is primarily based upon pricing and location. Although chemical prices have risen slightly over the last three years, we have been able to partially reduce our costs through improved efficiencies and capital expenditures. In connection with our focus on the growing bio-energy market, we sell tall oil, a by-product of our production process which is used as both a chemical additive and as a green energy source. In 2012, we generated €11.6 million from the sale of tall oil. We currently expect the proceeds from the sale of tall oil to remain stable in future periods.

The distribution of our pulp sales by end customer are set out in the following table for the periods indicated:

Our global sales and marketing group is responsible for conducting all sales and marketing of the pulp produced at our mills and currently has approximately 19 employees engaged full time in such activities. This group largely handles all European and North American sales directly. Sales to Asia are made directly or through commission agents overseen by our sales group. The global sales and marketing group handles sales to approximately 200 customers. We coordinate and integrate the sales and marketing activities of our German mills to realize on a number of synergies between them. These include reduced overall administrative and personnel costs and coordinated selling, marketing and transportation activities. We also coordinate sales from the Celgar mill with our German mills on a global basis, thereby providing our larger customers with seamless service across all major geographies. In marketing our pulp, we

23

Table of Contents

seek to establish long-term relationships by providing a competitively priced, high-quality, consistent product and excellent service. In accordance with customary practice, we maintain long-standing relationships with our customers pursuant to which we periodically reach agreements on specific volumes and prices.

Our pulp sales are on customary industry terms. At December 31, 2012, we had no material payment delinquencies. In 2012, one customer accounted for 11% of our pulp sales. In 2011, no single customer accounted for more than 10% of our pulp sales. In 2010, one customer which purchased for several of its mills accounted for 11% of pulp sales. We do not believe our pulp sales are dependent upon the activities of any single customer.

Approximately 54%, 58% and 55% of our sales were to tissue and specialty paper product manufacturers for the years ended December 31, 2012, 2011 and 2010, respectively. The balance of our sales for such periods was to other paper product manufacturers. Over the last five years, our sales to tissue and specialty paper product manufacturers have increased by over 15%. Generally such customers are not as sensitive to cyclical declines in demand caused by downturns in economic activity.

Transportation

We transport our NBSK pulp generally by truck, rail and ocean carriers through third-party carriers. Our carrier contracts are generally from one to two years.

Our German mills are currently the only market kraft pulp producers in Germany, which is the largest import market for kraft pulp in Europe. We therefore have a competitive transportation cost advantage compared to Canadian and Northern European pulp producers when shipping to customers in Europe. Due to the location of our German mills, we are able to deliver pulp to many of our customers primarily by truck. Most trucks that deliver goods into Eastern Germany generally do not have significant backhaul opportunities as the region is primarily an importer of goods. We are therefore frequently able to obtain relatively low backhaul freight rates for the delivery of our products to many of our customers. Since many of our customers are located within a 500 kilometer radius of our German mills, we can generally supply pulp to customers of these mills faster than our competitors because of the short distances between the mills and our customers.

The Celgar mill’s pulp is transported to customers by rail, truck and ocean carrier using third party warehouses to ensure timely delivery. The majority of Celgar’s pulp for overseas markets is initially delivered primarily by rail to the Port of Vancouver for shipment overseas by ocean carrier. Based in Western Canada, the Celgar mill is well positioned to service Asian customers. The majority of the Celgar mill’s pulp for domestic markets is shipped by rail to third party warehouses in the U.S. or directly to the customer.

In each of the years ended December 31, 2012, 2011 and 2010, outbound transportation costs comprised approximately 9% of our total consolidated cost of sales. Generally, in recent years, our transportation costs have increased due to increases in fuel costs and lower shipping capacity. As a result, we have taken initiatives to target sales to the most “freight logical” customers for overseas sales.

Capital Expenditures

In 2012, we continued with our capital investment programs designed to increase pulp and green energy production capacity, reduce costs and improve efficiency and environmental performance at our mills. The improvements made at our mills over the years have reduced operating costs and increased the competitive position of our facilities.

24

Table of Contents

Total capital expenditures at our mills are set out in the following table for the periods indicated:

Capital investments at the Rosenthal mill in 2012 related primarily to the mill’s recovery boiler upgrade, which we believe will reduce our wastewater fees, while, in 2011, they related primarily to the installation of a new chipper and upgrades to the recovery process. In 2010, capital expenditures related mainly to the upgrade of a bleaching line and a washer project which helped offset three years of wastewater fees that would otherwise be payable.

Capital investments at the Stendal mill in 2012 related primarily to the commencement of Project Blue Mill. In 2011 and 2010, capital investments related mainly to relatively small projects designed to improve safety and environmental performance as well as improve the overall efficiency of the mill.

In 2012, the Stendal mill commenced Project Blue Mill to increase production and efficiency at the mill through debottlenecking initiatives, including the installation of an additional 40 MW steam turbine. Project Blue Mill is estimated to require approximately €40.0 million in capital expenditures over about 21 months, which will be primarily funded through €12.0 million of non-refundable German government grants and a new €17.0 million five-year amortizing secured term debt facility, of which 80% will be government guaranteed. The balance of Project Blue Mill will be funded through operating cash flow of the Stendal mill and up to an aggregate of €6.5 million in pro rata shareholder loans from Mercer Inc. and Stendal’s noncontrolling shareholder. Project Blue Mill is currently expected to be completed and start to generate electricity sales in or about September 2013. As of December 31, 2012, we had expended an aggregate €13.3 million on Project Blue Mill.

Certain of our capital investment programs in Germany were partially financed through government grants made available by German federal and state governments. Under legislation adopted by the federal and certain state governments of Germany, government grants are provided to qualifying businesses operating in Eastern Germany to finance capital investments. The grants are made to encourage investment and job creation. For example, the government grants received in connection with Project Blue Mill require us to maintain the employment of core employees for five years after completion of the project. Currently, grants are available for up to 30% of the cost of qualified investments. Previously, government grants were available for up to 35% of the cost of qualified investments, such as for the construction of our Stendal mill. These grants at the 35% of cost level required that at least one permanent job be created for each €0.5 million of capital investment eligible for such grants and that such jobs be maintained for a period of five years from the completion of the capital investment project. Generally, government grants are not repayable by a recipient unless it fails to complete the proposed capital investment or, if applicable, fails to create or maintain the requisite amount of jobs. In the case of such failure, the government is entitled to revoke the grants and seek repayment unless such failure resulted from material unforeseen market developments beyond the control of the recipient, wherein the government may refrain from reclaiming previous grants. Pursuant to such legislation in effect at the time, the Stendal mill received approximately €278.0 million of government grants. We believe that we are in compliance in all material respects with all of the terms and conditions governing the government grants we have received in Germany. See “Legal Proceedings”.

The following table sets out for the periods indicated the effect of these government grants on the recorded value of such assets in our Consolidated Balance Sheets:

The following table sets forth the gross amount of all government grants we have received and capitalized in our balance sheet, the associated amortization and the resulting net balance we include in our property, plant and equipment for the periods indicated:

Qualifying capital investments at industrial facilities in Germany that reduce effluent discharges offset wastewater fees that would otherwise be required to be paid. For more information about our environmental capital expenditures, see “—Environmental”.

In 2012, capital expenditures at the Celgar mill includes a project to recover/recycle chemicals from the mill’s effluent, referred to as the “GAP Project”, while in 2011 such expenditures related to a project to improve the Celgar mill’s fiber line and oxygen delignification process, referred to as the “Oxygen Delignification Project” and the GAP Project. We completed the Celgar Energy Project in 2010 to increase the mill’s production of “green” energy and optimize its power generation capacity. The project cost approximately C$64.7 million (€49.0 million) and included the installation of a second turbine with a design capacity of 48 MW. The project increased the Celgar mill’s installed generating capacity to 100 MW and upgraded the mill’s power boiler and steam facilities.

In October 2009, as part of the GTP, the Canadian government, through Natural Resources Canada, referred to as “NRCan”, agreed to provide approximately C$57.7 million in credits towards the capital costs to improve energy efficiency or effect environmental improvements at the Celgar mill. Of the same, we used approximately C$46.8 million in connection with the Celgar Energy Project. Such credits reduced the cost basis of the assets purchased and were not recorded in our income. The balance of the credits were utilized by the Celgar mill on other qualifying projects. We utilized approximately C$10.9 million of our allocated GTP funding towards the Oxygen Delignification Project and several small projects at our Celgar mill.

Excluding costs for projects financed through government grants, capital expenditures for all of our mills in 2013 are expected to be approximately €32.0 million, comprised principally of expenditures on Project Blue Mill at our Stendal mill and an array of small projects at our other mills.

Environmental

Our operations are subject to a wide range of environmental laws and regulations, dealing primarily with water, air and land pollution control. We devote significant management and financial resources to comply with all applicable environmental laws and regulations. Our total capital expenditures on environmental projects at our mills were approximately €9.3 million in 2012 (approximately €7.1 million in 2011).

26

Table of Contents

We believe we have obtained all required environmental permits, authorizations and approvals for our operations. We believe our operations are currently in substantial compliance with the requirements of all applicable environmental laws and regulations and our respective operating permits.

Under German state environmental rules relating to effluent discharges, industrial users are required to pay wastewater fees based upon the amount of their effluent discharge. These rules also provide that an industrial user which undertakes environmental capital expenditures and lowers certain effluent discharges to prescribed levels may offset the amount of these expenditures against the wastewater fees that they would otherwise be required to pay. We estimate that the aggregate wastewater fees we saved in 2012 as a result of environmental capital expenditures and initiatives to reduce allowable emissions and discharges at our Stendal mill was approximately €4.2 million. The estimated amount of accrued wastewater fees we expect to recover at our Rosenthal mill is approximately €6.6 million. Capital investment programs and other environmental initiatives at our German mills mostly offset the wastewater fees that were payable for 2012 and we believe they will ensure that our operations continue in substantial compliance with prescribed standards.

Environmental compliance is a priority for our operations. To ensure compliance with environmental laws and regulations, we regularly monitor emissions at our mills and periodically perform environmental audits of operational sites and procedures both with our internal personnel and outside consultants. These audits identify opportunities for improvement and allow us to take proactive measures at the mills as considered appropriate.

The Rosenthal mill has a relatively modern biological wastewater treatment and oxygen bleaching facility. We have significantly reduced our levels of absorbable organic halogen discharge at the Rosenthal mill and we believe the Rosenthal mill’s absorbable organic halogen and chemical oxygen demand discharges are in compliance with the standards currently mandated by the German government.

The Stendal mill is in substantial compliance with applicable environmental laws, regulations and permits. Management believes that, as the Stendal mill is a state-of-the-art facility, it will be able to continue to operate in compliance with the applicable environmental requirements.

The Celgar mill has been in substantial compliance with applicable environmental laws, regulations and permits. In 2012, after a hearing, the Celgar mill was required to pay C$30,000 as a fine and C$120,000 as a contribution to a conservation trust fund for environmental projects in respect of a minor 2008 spill of diluted black liquor in the nearby Columbia River. The spill was promptly reported by the mill to authorities at the time of occurrence and remediated to the satisfaction of the overseeing environmental authorities.

The Celgar mill operates two landfills, one of which is an older site that the mill is in the process of decommissioning. The mill is continuing work on finalizing a closure plan for such site and then reviewing such plan with the British Columbia Ministry of Environment, or “MOE”. A portion of this older landfill is still being utilized. We currently expect to finalize our closure plan in 2013 and receive MOE approval for it in 2014. The actual closure activities shall be effected pursuant to a timetable agreed to by the mill and the MOE. The cost of closing the landfill is expected to be approximately €2.4 million.

Future regulations or permits may place lower limits on allowable types of emissions, including air, water, waste and hazardous materials, and may increase the financial consequences of maintaining compliance with environmental laws and regulations or conducting remediation. Our ongoing monitoring and policies have enabled us to develop and implement effective measures to maintain emissions in substantial compliance with environmental laws and regulations to date in a cost-effective manner. However, there can be no assurances that this will be the case in the future.

Climate Change

There are differing scientific studies and opinions relating to the severity, extent and speed at which climate change is or may be occurring. As a result, we cannot identify and predict all of the consequences of climate change on our business and operations.

27

Table of Contents

So far, the potential and/or perceived effects of climate change and social and governmental responses to it have created both business opportunities and the potential for negative consequences for our business.

The focus on climate change has generated a substantial increase in demand and in legislative requirements for “carbon neutral” or “green” energy in both Europe and, increasingly, in North America. Pulp mills consume wood residuals, being wood chips and pulp logs, as the base raw material for their production process. Wood chips are residuals left over from lumber production and pulp logs are generally lower quality logs left over from logging that are unsuitable for the production of lumber.

As part of their production process, our mills take wood residuals and process them through a digester where cellulose is separated from the wood to be used in pulp production and the remaining residuals, called “black liquor”, is used for green energy production. As a result of their use of wood residuals and because our mills generate combined heat and power, they are efficient producers of energy. This energy is carbon neutral and produced from a renewable source. Our relatively modern mills generate a substantial amount of energy that is surplus to their requirements.

These factors, along with governmental initiatives in respect of renewable or green energy legislation, have provided business opportunities for us to enhance our generation and sales of green energy to regional utilities. In early 2012 we commenced Project Blue Mill, a project at our Stendal mill to install a new 40 MW steam turbine which we expect will initially produce an additional 109,000 MWh of surplus renewable electricity.

We are constantly exploring other initiatives to enhance our generation and sales of surplus green energy and chemical by-products. Other potential opportunities that may result from climate change include:

At this time, we cannot predict which, if any, of these potential opportunities will be available to, or realized by, us or their economic effect on our business.

While all of the specific consequences to our business from climate change are not yet predictable, the most visible negative consequence is that the focus on renewable energy will continue to create greater demand for the wood residuals or fiber that is consumed by our mills as part of their production process.

In Germany, since 2006, the price and supply of wood residuals have been affected by an increasing demand from alternative or renewable energy producers and governmental initiatives for carbon neutral energy. Over the long term, this non-traditional demand for fiber is expected to increase in Europe. Additionally, the growing interest and focus in British Columbia for renewable green energy is also expected to create additional competition for such fiber in that region over time. Such additional demand for wood residuals may increase the competition and prices for wood residuals over time. See “—Production Costs—Fiber”.

Governmental action or legislation may also have an important effect on the demand and prices for wood residuals. As governments pursue green energy initiatives, they risk creating incentives and demand for wood residuals from renewable energy producers that “cannibalizes” or adversely affects existing traditional users, such as lumber and pulp and paper producers. We are continually engaged in dialogue with government to educate and try to ensure potential initiatives recognize the traditional and continuing role of our mills in the overall usage of forestry resources and the economies of local communities.

Other potential negative consequences from climate change over time that may affect our business include:

Human Resources

We currently employ approximately 1,500 people. We have approximately 1,044 employees working in our German operations, including our wood procurement, transportation and sales subsidiaries. In addition, there are approximately 16 people employed at the office we maintain in Vancouver, British Columbia, Canada. Celgar currently employs approximately 443 people in its operations, the vast majority of which are unionized.

Rosenthal, which employs approximately 441 people, is bound by collective agreements negotiated with Industriegewerkschaft Bergbau, Chemie, Energie, or “IGBCE”, a national union that represents pulp and paper workers. In December 2011, we successfully negotiated a new agreement with IGBCE substantially upon the same terms as the previous labor contract. The new collective agreement provided for a one-time payment of €200 per employee, an approximately 3.0% wage increase in 2012 and a further 1.6% wage increase in 2013. This collective agreement has an 18-month term and is scheduled to expire in May 2013.

Stendal and its subsidiaries employ approximately 597 people. In 2011, Stendal entered into a seven-year collective agreement with IGBCE effective July 2011. Since, prior to entering into this collective agreement, Stendal’s employees had relatively lower wages compared to their peers at other German pulp mills, this agreement provided for an approximately 5.5% wage increase in 2012. The collective agreement provides for a further 2.5% minimum annual wage increase from 2013 to 2015. The collective agreement is scheduled to expire in 2018.

We negotiated a five-year collective agreement in November 2012, effective May 1, 2012, with our hourly workers at the Celgar mill to replace the collective agreement which expired on April 30, 2012. The agreement provides for lump sum payments of $3,750 for all active employees in 2012 and 2013 and wage increases of 2.0%, 2.5% or 3.0% in each of 2014, 2015 and 2016. The collective agreement is scheduled to expire in April 2017.

We consider the relationships with our employees to be good. Although no assurances can be provided, we have not had any significant work stoppages at any of our operations and we would therefore expect to enter into new labor agreements with our workers when the current labor agreements expire without any significant work stoppages.

Senior Notes

In November 2010, we issued $300.0 million in aggregate principal amount of 9.5% Senior Notes due 2017, referred to as the “Senior Notes” to principally refinance our 9.25% Senior Notes due 2013, referred to as the “2013 Senior Notes”. The Senior Notes bear interest at a rate of 9.5% per annum, payable semi-annually in arrears on December 1 and June 1, commencing June 1, 2011. The Senior Notes mature on December 1, 2017. The Senior Notes are our senior unsecured obligations and, accordingly, rank junior in right of payment to all existing and future secured indebtedness and all indebtedness and liabilities of our subsidiaries, equal in right of payment with all of our existing and future unsecured senior indebtedness and senior in right of payment to any current or future subordinated indebtedness. The Senior Notes were issued under an indenture which, among other things, restricts our ability and the ability of our restricted subsidiaries under the indenture to: (i) incur additional indebtedness or issue preferred stock; (ii) pay dividends or make other distributions to our stockholders; (iii) purchase or redeem capital stock or subordinated indebtedness; (iv) make investments; (v) create liens and enter into sale and lease back transactions; (vi) incur restrictions on the ability of our restricted subsidiaries to pay dividends or make other payments to us; (vii) sell assets; (viii) consolidate or merge with or into other companies or transfer all or substantially all of our assets; and (ix) engage in transactions with affiliates. These limitations are subject to important qualifications and exceptions.

In order to take into account the nature of the non-recourse “project financing” of the loan facility for our Stendal mill and to enhance our financing flexibility, the indenture governing our Senior Notes provides for a “Restricted Group” and an “unrestricted group”. The terms of the indenture are applicable to the Restricted Group and are generally not applicable to the unrestricted group. Currently, the Restricted Group is comprised of Mercer Inc., the Rosenthal and Celgar mills and certain holding subsidiaries. The Restricted Group excludes our Stendal mill. The working capital facilities and Rosenthal Investment Loan at our Rosenthal and Celgar mills are obligations of the Restricted Group. The Stendal Loan Facility and Blue Mill Facility are obligations of our unrestricted group.

We have purchased and cancelled an aggregate of approximately $15.6 million in aggregate principal amount of our Senior Notes in connection with our share and debt repurchase program. As at December 31, 2012, approximately $284.4 million in aggregate principal amount of Senior Notes remained outstanding.

Stendal Loan Facility

In August 2002, Stendal entered into a senior €828.0 million project finance facility, referred to as the “Stendal Loan Facility”. The Stendal Loan Facility was comprised of several tranches which covered, among other things, project construction and development costs, financing and start-up costs and working capital, as well as the financing of the debt service reserve account, or “DSRA”, approved cost overruns and a revolving loan facility that covered time lags for receipt of grant funding and value-added tax refunds, which has been repaid. The DSRA is an account maintained to hold and, if needed, pay up to one year’s principal and interest due under the facility as partial security for the lenders. Other than the revolving working capital tranche, no further advances are currently available under the Stendal Loan Facility.

Pursuant to the Stendal Loan Facility, interest accrues at variable rates between Euribor plus 0.90% and Euribor plus 1.80% per year. The facility provides for Stendal to manage its risk exposure to interest rate risk, currency risk and pulp price risk by way of interest rate swaps, Euro and U.S. dollar swaps and pulp hedging transactions, subject to certain controls, including certain maximum notional and at-risk amounts. Pursuant to the terms of the facility, in 2002 Stendal entered into interest rate swap agreements in respect of borrowings to fix most of the interest costs under the Stendal Loan Facility at a rate of 5.28% plus an applicable margin, until final payment in October 2017.

The tranches are generally repayable in installments and the Stendal Loan Facility matures in September 2017.

In February 2009, we completed an agreement with Stendal’s lending syndicate to amend the Stendal Loan Facility, referred to as the “Amendment”. Pursuant to the Amendment, Stendal’s obligation to repay €164.0 million of scheduled principal payments, referred to as the “Deferred Amount”, is deferred until maturity of the facility in September 2017. Until the Deferred Amount is repaid in full, Stendal may not make distributions, in the form of interest and capital payments on shareholder debt or dividends on equity invested, to its shareholders, including us. The Amendment also provides for a 100% cash sweep, referred to as the “Cash Sweep”, of any excess cash of Stendal which will be used first to fund the DSRA to a level sufficient to service the amounts due and payable under the Stendal Loan Facility during the then following 12 months, or “Fully Funded”, and second to prepay the Deferred Amount. Not included in the Cash Sweep is an amount of €15.0 million which Stendal is permitted to retain for working capital purposes. The DSRA balance as at December 31, 2012 was approximately €33.0 million.

The Amendment implemented a permitted leverage ratio of total debt under the Stendal Loan Facility to EBITDA, or “Senior Debt/EBITDA Cover Ratio”, to be effective from December 31, 2009 and to decline over time from 13.0x on its effective date to 4.5x on June 30, 2017. Subsequently, Stendal’s lending syndicate waived compliance with the permitted leverage ratio for the year ended December 31, 2009. The Amendment also revised the Stendal Loan Facility’s annual debt service cover ratio, or “Annual Debt Ratio”, requirement to be at least 1.1x for the period from December 31, 2011 to December 31, 2013 and 1.2x from January 1, 2014 until maturity.

The Amendment includes the following as events of default:

The Amendment provides that Stendal and its shareholders may, once per fiscal year, cure a deficiency in each of the Annual Debt Ratio or the Senior Debt/EBITDA Cover Ratio by way of a capital contribution or fully subordinated shareholder loan to Stendal in the amount necessary to cure such deficiency and thereby prevent the occurrence of an event of default. Our ability to fund this cure is substantially limited by the terms of the Senior Notes.

The tranches under the Stendal Loan Facility are severally guaranteed by German federal and state governments in respect of an aggregate of 80% of the principal amount of these tranches. Under the guarantees, the German federal and state governments that provide the guarantees are responsible for the performance of our payment obligations for the guaranteed amounts. Such governmental guarantees permit the Stendal Loan Facility to benefit from lower interest costs and other credit terms than would otherwise be unavailable. The Stendal Loan Facility is secured by substantially all of the assets of Stendal.

In order to permit Stendal to enter into the Blue Mill Facility (as described below), the Stendal Loan Facility was amended. In particular, the funds in the DSRA may now be used to bridge any deficiency in funding for Project Blue Mill, payments to Stendal’s capital reserves are no longer an equity cure measure under the Stendal Loan Facility and the Stendal Loan Facility now has a cross-default provision with the Blue Mill Facility.

In connection with the Stendal Loan Facility, we entered into a shareholders’ undertaking agreement, referred to as the “Undertaking”, dated August 26, 2002, as amended, with Stendal’s then minority shareholders

31

Table of Contents

and the lenders in order to finance the shareholders’ contribution to the Stendal mill. Under the terms of the Undertaking, we have agreed, for as long as Stendal has any liability under the Stendal Loan Facility, to retain control over at least 51% of the voting shares of Stendal.

Since completion of the Stendal mill in September 2004, Stendal has repaid €215.0 million of the Stendal Loan Facility. As at December 31, 2012, the principal amount outstanding under the Stendal Loan Facility was €452.9 million.

Blue Mill Facility

In January 2012, our Stendal mill entered into the Blue Mill Facility, being a €17.0 million amortizing term facility, to finance Project Blue Mill. The Blue Mill Facility, 80% of which is guaranteed by the State of Saxony-Anhalt, bears interest at a rate of Euribor plus 3.5% per annum and is scheduled to mature in September 2017. The Blue Mill Facility’s annual debt service cover ratio and permitted ratio of total debt to EBITDA are identical to the Annual Debt Ratio and the Senior Debt/EBITDA Cover Ratio in the Stendal Loan Facility (including cure provisions). There is also a cross default for the Stendal Loan Facility. The Blue Mill Facility will be repaid in nine half-yearly installments, together with accrued interest commencing September 30, 2013 and will be non-recourse to Mercer Inc. This facility was undrawn as at December 31, 2012.

Rosenthal Loan Facilities

Our Rosenthal mill has the following credit facilities:

As of December 31, 2012, the total amount of funds available under the working capital facilities associated with the Rosenthal mill was €26.2 million.

Celgar Working Capital Facility

Our Celgar mill has a C$40.0 million revolving working capital credit facility that matures May 2013, referred to as the “Celgar Working Capital Facility”. It is available by way of: (i) Canadian and U.S. denominated advances which bear interest at a designated prime rate plus 2.0% for Canadian advances and at a

32

Table of Contents

designated base rate plus 2.0% per annum for U.S. advances; (ii) banker’s acceptance equivalent loans which bear interest at the applicable Canadian dollar bankers’ acceptance rate plus 3.75% per annum; and/or (iii) LIBOR advances which bear interest at the applicable LIBOR plus 3.75% per annum. The Celgar Working Capital Facility also incorporates a C$3.0 million letter of credit sub line. Celgar is also required to pay a 0.5% per annum standby fee monthly in arrears on any unutilized portion of the revolving facility. Availability of drawdowns under the facility is subject to a borrowing base limit that is based upon the Celgar mill’s eligible accounts receivable and inventory levels from time to time. The Celgar Working Capital Facility is secured by, among other things, a first fixed charge on the current assets of Celgar.

As at December 31, 2012, C$24.0 million of funds were available under the Celgar Working Capital Facility.

Our business is highly cyclical in nature.

The pulp business is highly cyclical in nature and markets are characterized by periods of supply and demand imbalance, which in turn affects prices. Pulp markets are highly competitive and are sensitive to cyclical changes in the global economy, industry capacity and foreign exchange rates, all of which can have a significant influence on selling prices and our operating results. The length and magnitude of industry cycles have varied over time but generally reflect changes in macro-economic conditions and levels of industry capacity. Pulp is a commodity that is generally available from other producers. Because commodity products have few distinguishing qualities from producer to producer, competition is generally based upon price, which is generally determined by supply relative to demand.

Industry capacity can fluctuate as changing industry conditions can influence producers to idle production capacity or permanently close mills. In addition, to avoid substantial cash costs in idling or closing a mill, some producers will choose to operate at a loss, sometimes even a cash loss, which can prolong weak pricing environments due to oversupply. Oversupply of our products can also result from producers introducing new capacity in response to favorable pricing trends.

Demand for pulp has historically been determined primarily by general global macroeconomic conditions and has been closely tied to overall business activity. From 2006 to mid-2008, pulp prices steadily improved. However, the global economic crisis in the latter half of 2008 resulted in a sharp decline of pulp prices from a high of €900 per ADMT to €635 per ADMT at the end of 2008. Pulp prices began to increase in the second half of 2009 and continued to increase to record levels through June of 2010, before declining slightly in the fourth quarter of 2010. Pulp prices again rebounded to record levels in the first half of 2011 but declined sharply in the latter part of the year, primarily due to economic uncertainty in Europe and credit tightening in China. Economic uncertainty in Europe and China, respectively, impacted both demand and prices. In 2012, list prices were on average approximately 15% lower than 2011. At the end of 2012, list prices for NBSK pulp were approximately $810 in Europe, $870 in North America and $655 in China.

Accordingly, prices for pulp are driven by many factors outside our control, and we have little influence over the timing and extent of price changes, which are often volatile. Because market conditions beyond our control determine the price for pulp, prices may fall below our cash production costs, requiring us to either incur short-term losses on product sales or cease production at one or more of our mills. Therefore, our profitability depends on managing our cost structure, particularly raw materials which represent a significant component of our operating costs and can fluctuate based upon factors beyond our control. If the prices of our products decline, or if prices for our raw materials increase, or both, our results of operations and cash flows could be materially adversely affected.

Our level of indebtedness could negatively impact our financial condition and results of operations.

As of December 31, 2012, we had approximately €711.4 million of indebtedness outstanding, of which €452.9 million relates to the Stendal Loan Facility. We may also incur additional indebtedness in the future. Our high debt levels may have important consequences for us, including, but not limited to the following:

35

Table of Contents

The indenture governing our Senior Notes and our bank credit facilities contain restrictive covenants which impose operating and other restrictions on us and our subsidiaries. These restrictions will affect, and in many respects will limit or prohibit, our ability to, among other things, incur or guarantee additional indebtedness or enter into sale/leaseback transactions, pay dividends or make distributions on capital stock or redeem or repurchase capital stock, make investments or acquisitions, create liens and enter into mergers, consolidations or transactions with affiliates. The terms of our indebtedness also restrict our ability to sell certain assets, apply the proceeds of such sales and reinvest in our business.

Certain of the agreements governing our indebtedness, including the Stendal Loan Facility, have covenants that require us to maintain prescribed financial ratios and tests. Failure to comply with such covenants could result in events of default and could have a material adverse effect on our liquidity, results of operations and financial condition.

Our ability to repay or refinance our indebtedness will depend on our future financial and operating performance. Our performance, in turn, will be subject to prevailing economic and competitive conditions, as well as financial, business, legislative, regulatory, industry and other factors, many of which are beyond our control. Our ability to meet our future debt service and other obligations, in particular the Stendal Loan Facility, may depend in significant part on the extent to which we can implement successfully our business strategy. We cannot assure you that we will be able to implement our strategy fully or that the anticipated results of our strategy will be realized.

A weakening of the global economy could adversely affect our business and financial results and have a material adverse effect on our liquidity and capital resources.

Principally, as pulp demand has historically been determined by general global macroeconomic activities, demand and prices for our product have historically decreased substantially during economic slowdowns. Additionally, restricted credit availability restrains our customers’ ability or willingness to purchase our products resulting in lower revenues. Depending on their severity and duration, the effects and consequences of a global economic downturn could have a material adverse effect on our liquidity and capital resources, including our ability to raise capital, if needed, and otherwise negatively impact our business and financial results.

Cyclical fluctuations in the price and supply of our raw materials could adversely affect our business.

Our main raw material is fiber in the form of wood chips and pulp logs. Such fiber is cyclical in terms of both price and supply. The cost of wood chips and pulp logs is primarily affected by the supply and demand for lumber. Demand for these raw materials is generally determined by the volume of pulp and paper products produced globally and regionally. Since 2006, generally higher energy prices and a focus on, and governmental initiatives related to, “green” or renewable energy have led to an increase in renewable energy projects in Europe, including Germany. Demand for wood residuals from such energy producers, combined with lower harvesting rates, has generally put upward pressure on prices for wood residuals such as wood chips in Germany and its neighboring countries. This has resulted in higher fiber costs for our German mills and such trend could continue to put further upward pressure on wood chip prices.

36

Table of Contents

Similarly, North American sawmill activity declined significantly during the recession, reducing the supply of chips and availability of pulp logs to our Celgar mill. Additionally, North American energy producers are exploring the viability of renewable energy initiatives and governmental initiatives in this field are increasing, all of which could lead to higher demand for sawmill residual fiber, including chips. The cyclical nature of pricing for these raw materials represents a potential risk to our profit margins if pulp producers are unable to pass along price increases to their customers or we cannot offset such costs through higher prices for our surplus energy.

We do not own any timberlands or have any long-term governmental timber concessions and we currently have few long-term fiber contracts at our German operations. Raw materials are available from a number of suppliers and we have not historically experienced material supply interruptions or substantial sustained price increases. However, our requirements have increased and may continue to do so as we expand capacity through capital projects or other efficiency measures at our mills. As a result, we may not be able to purchase sufficient quantities of these raw materials to meet our production requirements at prices acceptable to us during times of tight supply. In addition, the quantity, quality and price of fiber we receive could be affected as a result of industrial disputes, material curtailments or shut-down of operations by suppliers, government orders and legislation (including new taxes or tariffs), weather conditions, acts of God and other events beyond our control. An insufficient supply of fiber or reduction in the quality of fiber we receive would materially adversely affect our business, financial condition, results of operations and cash flow. In addition to the supply of wood fiber, we are dependent on the supply of certain chemicals and other inputs used in our production facilities. Any disruption in the supply of these chemicals or other inputs could affect our ability to meet customer demand in a timely manner and could harm our reputation. Any material increase in the cost of these chemicals or other inputs could have a material adverse effect on our business, results of operations, financial condition and cash flows.

We operate in highly competitive markets.

We sell our pulp globally, with a large percentage sold in Europe, North America and Asia. The markets for pulp are highly competitive. A number of other global companies compete in each of these markets and no company holds a dominant position. Our pulp is considered a commodity because many companies produce similar and largely standardized products. As a result, the primary basis for competition in our markets has been price. Many of our competitors have greater resources and lower leverage than we do and may be able to adapt more quickly to industry or market changes or devote greater resources to the sale of products than we can. There can be no assurance that we will continue to be competitive in the future. Prices for our products are affected by many factors outside of our control and we have no influence over the timing and extent of price changes, which are often volatile. Our profitability with respect to these products depends, in part, on managing our costs, particularly raw material and energy costs which represent significant components of our operating costs and can fluctuate based upon factors beyond our control.

The global pulp market has historically been characterized by considerable swings in prices which have and will result in variability in our earnings. Prices are typically denominated in U.S. dollars.

We are exposed to currency exchange rate and interest rate fluctuations.

The majority of our sales are in products quoted in U.S. dollars while most of our operating costs and expenses, other than those of the Celgar mill, are incurred in Euros. In addition, all of the products sold by the Celgar mill are quoted in U.S. dollars and the Celgar mill costs are primarily incurred in Canadian dollars. Our results of operations and financial condition are reported in Euros. As a result, our revenues are adversely affected by a decrease in the value of the U.S. dollar relative to the Euro and to the Canadian dollar. Such shifts in currencies relative to the Euro and the Canadian dollar reduce our operating margins and the cash flow available to fund our operations and to service our debt. This could have a material adverse effect on our business, financial condition, results of operations and cash flows.

In 2002, Stendal entered into variable-to-fixed interest rate swaps to fix interest payments under the Stendal Loan Facility, which has kept Stendal from benefiting from the general decline in interest rates that ensued. These derivatives are marked to market at the end of each reporting period and all unrealized gains and losses are recognized as earnings or losses for the relevant reporting periods.

We use derivatives to manage certain risk which has caused significant fluctuations in our operating results.

We use derivative instruments to limit our exposure to interest rate and pulp price fluctuations. Concurrently with entering into the Stendal financing, Stendal entered into variable-to-fixed rate interest swaps for the full term of our Stendal Loan Facility to manage its interest rate risk exposure with respect to the full principal amount of this facility. Because we effectively fixed the rate on our Stendal Loan Facility, the value of our derivative position moves inversely to interest rates. We have also recently entered into fixed price pulp swap contracts with a bank.

We record unrealized gains or losses on our derivative instruments when they are marked to market at the end of each reporting period and realized gains or losses on them when they are settled. These unrealized and realized gains and losses can materially impact our operating results for any reporting period.

If any of the variety of instruments and strategies we utilize are not effective, we may incur losses which may have a materially adverse effect on our business, financial condition, results of operations and cash flow. The purpose of our derivative activity may also be considered speculative in nature; we do not use these instruments with respect to any pre-set percentage of revenues or other formula, but either to augment our potential gains or reduce our potential losses depending on our perception of future economic events and developments.

We are subject to extensive environmental regulation and we could have environmental liabilities at our facilities.

Our operations are subject to numerous environmental laws as well as permits, guidelines and policies. These laws, permits, guidelines and policies govern, among other things:

In addition, as a result of our operations, we may be subject to remediation, clean-up or other administrative orders or amendments to our operating permits, and we may be involved from time to time in administrative and judicial proceedings or inquiries. Future orders, proceedings or inquiries could have a material adverse effect on our business, financial condition and results of operations. Environmental laws and land use laws and regulations are constantly changing. New regulations or the increased enforcement of existing laws could have a material adverse effect on our business and financial condition. In addition, compliance with regulatory requirements is expensive, at times requiring the replacement, enhancement or modification of equipment, facilities or operations. There can be no assurance that we will be able to maintain our profitability by offsetting any increased costs of complying with future regulatory requirements.

We are subject to liability for environmental damage at the facilities that we own or operate, including damage to neighboring landowners, residents or employees, particularly as a result of the contamination of soil, groundwater or surface water and especially drinking water. The costs of such liabilities can be substantial. Our potential liability may include damages resulting from conditions existing before we purchased or operated these facilities. We may also be subject to liability for any offsite environmental contamination caused by pollutants or hazardous substances that we or our predecessors arranged to transport, treat or dispose of at other locations. In addition, we may be held legally responsible for liabilities as a successor owner of businesses that we acquire or have acquired. Except for Stendal, our facilities have been operating for decades and we have not done invasive testing to determine whether or to what extent environmental contamination exists. As a result, these businesses may have liabilities for conditions that we discover or that become apparent, including liabilities arising from non-compliance with environmental laws by prior owners. Because of the limited availability of insurance coverage for environmental liability, any substantial liability for environmental damage could materially adversely affect our results of operations and financial condition.

Enactment of new environmental laws or regulations or changes in existing laws or regulations might require significant capital expenditures. We may be unable to generate sufficient funds or access other sources of capital to fund unforeseen environmental liabilities or expenditures.

Our business is subject to risks associated with climate change and social and government responses thereto.

Currently, there are differing scientific studies and opinions relating to the severity, extent and speed at which climate change is or may be occurring around the world. As a result, we are currently unable to identify and predict all of the specific consequences of climate change on our business and operations.

To date, the potential and/or perceived effects of climate change and social and government responses to it have created both opportunities, such as enhanced sales of surplus “green” energy, and risks for our business.

While all of the specific consequences from climate change are not yet predictable, we are subject to risks that government and social focus on and demand for “carbon neutral” or “green” energy will create greater demand for the wood residuals or fiber that is consumed by our pulp mills as part of their production process. In addition, governmental initiatives or legislation may also increase both the demand and prices for wood residuals. As governments pursue green energy initiatives, they may implement financial, tax, pricing or other legislated incentives for renewable energy producers that “cannibalize” or materially adversely affect fiber supplies for existing traditional users, such as lumber and pulp and paper producers.

Such additional demand for wood residuals and/or governmental initiatives may materially increase the competition and prices for wood residuals over time. This could increase our fiber costs and/or restrict our ability to acquire fiber at competitive prices or at all during times of shortages. If our fiber costs increase and we cannot pass on these costs to our customers or offset them through higher prices for our sales of surplus energy, it will negatively affect our operating margins, results of operations and financial position. If we cannot obtain the fiber required to operate our mills, we may have to curtail and/or shut down production. This could have a material adverse effect on operations, financial results and financial position.

Other potential risks to our business from climate change include:

39

Table of Contents

The occurrence of some or all of these events could have a material adverse effect on our operations and/or financial results.

Our operations require substantial capital and we may be unable to maintain adequate capital resources to provide for all of our capital requirements.

Our business is capital intensive and requires that we regularly incur capital expenditures to maintain our equipment, improve efficiencies and, as a result of changes to environmental regulations that require capital expenditures, bring our operations into compliance with such regulations. In addition, our senior management and board of directors may approve projects in the future that will require significant capital expenditures. Increased capital expenditures could have a material adverse effect on our cash flow and our ability to satisfy our debt obligations. If our available cash resources and cash generated from operations are not sufficient to fund our operating needs and capital expenditures, we would have to obtain additional funds from borrowings or other available sources or reduce or delay our capital expenditures. Recent global credit conditions and the downturn in the global economy have resulted in a significant decline in the credit markets and the overall availability of credit. Our indebtedness could adversely affect our financial health, limit our operations and impair our ability to raise additional capital. If this occurs, we may not be able to obtain additional funds on favorable terms or at all. If we cannot maintain or upgrade our equipment as may be required from time to time, we may become unable to manufacture products that compete effectively. An inability to make required capital expenditures in a timely fashion could have a material adverse effect on our growth, business, financial condition or results of operations.

Future acquisitions may result in additional risks and uncertainties in our business.

In order to grow our business, we may seek to acquire additional assets or companies. Our ability to pursue selective and accretive acquisitions will be dependent on management’s ability to identify, acquire, and develop suitable acquisition targets in both new and existing markets, but, in certain circumstances, acceptable acquisition targets might not be available. In pursuing acquisition and investment opportunities, we face competition from other companies having similar growth strategies, many of which may have substantially greater resources than us. Competition for these acquisitions or investment targets could result in increased acquisition or investment prices, higher risks and a diminished pool of businesses or assets available for acquisition.

Acquisitions also frequently result in recording of goodwill and other intangible assets, which are subject to potential impairments in the future that could have a material adverse effect on our operating results. Furthermore, the costs of integrating acquired businesses (including restructuring charges associated with the acquisitions, as well as other acquisition costs, such as accounting fees, legal fees and investment banking fees) could significantly impact our operating results.

Although we perform diligence on the businesses we purchase, in light of the circumstances of each transaction, an unavoidable level of risk remains regarding the actual condition of these businesses. We may not be able to ascertain the value or understand the potential liabilities of the acquired businesses and their operations until we assume operating control of the assets and operations of these businesses.

Furthermore, any future acquisitions of businesses or facilities could entail a number of risks, including:

40

Table of Contents

In addition, geographic and other expansions, acquisitions or joint ventures may require significant managerial attention, which may be diverted from our other operations. If we are unsuccessful in overcoming these risks, our business, financial condition or results of operations could be materially and adversely affected.

Changes in credit ratings issued by nationally recognized statistical 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, actions that we take, their view of the general outlook for our industry and their view of the general outlook for the economy. Actions taken by the rating agencies can include maintaining, upgrading or downgrading the current rating or placing the company on a watch list for possible future downgrading. Downgrading the credit rating of our debt securities or placing us on a watch list for possible future downgrading could limit our access to the credit markets, increase our cost of financing and have an adverse effect on the market price of our securities.

Project Blue Mill may not generate the results or benefits we expect.

Project Blue Mill is subject to customary risks and uncertainties inherent for large capital projects which could result in the project not completing on schedule or as budgeted. The Stendal mill could experience operating difficulties or delays during the start-up period when the new 40 MW turbine is being ramped up. Project Blue Mill may not increase the Stendal mill’s pulp production and energy generating capacity to the levels we had planned. Cost overruns, equipment breakdowns or failures to perform to design specifications could have a material adverse effect on our Stendal mill’s results of operations and financial performance.

We are subject to risks related to our employees.

The majority of our employees are unionized and we have collective agreements in place with our employees at all of our mills. Although we have not experienced any work stoppages in the past, there can be no assurance that we will be able to negotiate acceptable collective agreements or other satisfactory arrangements with our employees upon the expiration of our collective agreements. This could result in a strike or work stoppage by the affected workers. The registration or renewal of the collective agreements or the outcome of our wage negotiations could result in higher wages or benefits paid to union members. Accordingly, we could experience a significant disruption of our operations or higher on-going labor costs, which could have a material adverse effect on our business, financial condition, results of operations and cash flow.

We rely on government grants and guarantees and participate in European statutory programs.

We currently benefit from a subsidized capital expenditure program and lower cost of financing as a result of German federal and state government grants and guarantees at our Stendal mill. Should either the German federal or state governments be prohibited from honoring legislative grants and guarantees at Stendal, or should we be required to repay any such legislative grants, this may have a material adverse effect on our business, financial condition, results of operations and cash flow.

Since 2005, our German mills have benefitted from sales of emission allowances under the EU ETS. As a result of our Rosenthal and Stendal mills’ eligibility for special tariffs under the Renewable Energy Act, the amount of emissions allowances granted to our German mills under the EU ETS has been reduced. Additionally, all such German legislation is subject to amendment or change which could adversely affect the eligibility of our Rosenthal and Stendal mills to participate in this statutory program and/or the tariffs paid thereunder. As a result we cannot predict with any certainty the amount of future sales of surplus energy we may be able to generate.

We are dependent on key personnel.

Our future success depends, to a large extent, on the efforts and abilities of our executive and senior mill operating officers. Such officers are industry professionals many of whom have operated through multiple business cycles. Our officers play an integral role in, among other things:

Table of Contents

The loss of one or more of our officers could make us less competitive in these areas which could materially adversely affect our business, financial condition, results of operations and cash flows. We do not maintain any key person life insurance for any of our executive or senior mill operating officers.

We may experience material disruptions to our production.

A material disruption at one of our manufacturing facilities could prevent us from meeting customer demand, reduce our pulp and energy sales and/or negatively impact our results of operations. Any of our mills could cease operations unexpectedly due to a number of events, including:

Any such downtime or facility damage could prevent us from meeting customer demand for our products and/or require us to make unplanned capital expenditures. If any of our facilities were to incur significant downtime, our ability to meet our production capacity targets and satisfy customer requirements would be impaired and could have a material adverse effect on our business, financial condition, results of operations and cash flows.

If our long-lived assets become impaired, we may be required to record non-cash impairment charges that could have a material impact on our results of operations.

We review the carrying value of long-lived assets for impairment when events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. Should the markets for our products deteriorate or should we decide to invest capital differently or should other cash flow assumptions change, it is possible that we will be required to record non-cash impairment charges in the future that could have a material adverse effect on our results of operations.

We may incur losses as a result of unforeseen or catastrophic events, including the emergence of a pandemic, terrorist attacks or natural disasters.

The occurrence of unforeseen or catastrophic events, including the emergence of a pandemic or other widespread health emergency (or concerns over the possibility of such an emergency), terrorist attacks or natural

disasters, could create economic and financial disruptions, could lead to operational difficulties (including travel limitations) that could impair our ability to manage or operate our business and adversely affect our results of operations.

Our insurance coverage may not be adequate.

We have obtained insurance coverage that we believe would ordinarily be maintained by an operator of facilities similar to our mills. Our insurance is subject to various limits and exclusions. Damage or destruction to our facilities could result in claims that are excluded by, or exceed the limits of, our insurance coverage. Additionally, the weak global and financial markets have also reduced the availability and extent of credit insurance for our customers. If we cannot obtain adequate credit insurance for our customers, we may be forced to amend or curtail our planned operations which could negatively impact our sales revenues, results of operations and financial position.

We rely on third parties for transportation services.

Our business primarily relies upon third parties for the transportation of pulp to our customers, as well as for the delivery of our raw materials to our mills. Our pulp and raw materials are principally transported by truck, barge, rail and sea-going vessels, all of which are highly regulated. Increases in transportation rates can also materially adversely affect our results of operations.

Further, if our transportation providers fail to deliver our pulp in a timely manner, it could negatively impact our customer relationships and we may be unable to sell it at full value. If our transportation providers fail to deliver our raw materials in a timely fashion, we may be unable to manufacture pulp in response to customer orders. Also, if any of our transportation providers were to cease operations, we may be unable to replace them at a reasonable cost. The occurrence of any of the foregoing events could materially adversely affect our results of operations.

The price of our common stock may be volatile.

The market price of our common stock may be influenced by many factors, some of which are beyond our control, including those described above and the following:

In addition, there has been significant volatility in the market price and trading volume of securities of companies operating in the forest products industry that often has been unrelated to the operating performance of particular companies. Some companies that have had 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 would divert management’s attention and resources.

None.

We own the Rosenthal and Celgar mills and the underlying property. The Stendal mill is situated on property owned by Stendal, our 74.9% owned subsidiary. For a description of our mills, please see “Part I.—Item 1. Business—Our Mills and Product”.

We lease offices in Vancouver, British Columbia, Berlin, Arneburg and Hamburg, Germany, and Seattle, Washington.

At the end of 2012, substantially all of the assets relating to the Stendal mill were pledged to secure the Stendal Loan Facility and the Blue Mill Facility. The €3.5 million Rosenthal working capital facility is secured by certain land at the Rosenthal mill. The other working capital loan facilities established for the Rosenthal and Celgar mills are secured by first charges against the inventories and receivables at the respective mills.

In October 2005, our wholly-owned subsidiary, Zellstoff Celgar Limited, received a re-assessment for real property transfer tax payable in British Columbia, Canada, in the amount of approximately €3.0 million (C$4.5 million) in connection with the acquisition of the Celgar mill. We are currently contesting the re-assessment and we currently expect the Supreme Court of British Columbia to hold a hearing on this matter in 2013. The reassessment has been fully paid and the amount, if any, that may be reimbursed to us in connection with this matter remains uncertain.

In September of 2010, the Celgar mill received a letter from the Upper Columbia River Natural Resources Trustee Council, an organization consisting of aboriginal groups and US government representatives, referred to as the “Council”, alleging that, based on their preliminary assessment (the “Preliminary Assessment”), between 1961 to 1993, the Celgar mill had discharged chlorinated organic compounds into the Columbia River. The Preliminary Assessment was conducted to evaluate the need to conduct a formal natural resource damage assessment under the U.S. Comprehensive Environmental Response, Compensation and Liability Act, referred to as “CERCLA”. Although we did not acquire the Celgar mill until 2005, and the Celgar mill’s alleged discharges occurred prior to our acquisition of the mill, the Council determined to proceed with a formal natural resource damage assessment under the CERCLA. Although at this time it is unclear as to whether any harm was caused by these alleged discharges and, in any event, we do not believe we are liable, due to the preliminary nature of the assessment, we cannot at this time quantify the costs, if any, associated with this matter.

In January 2012, we served a Notice of Intent to Submit a Claim to Arbitration on the Government of Canada, referred to as the “NAFTA Notice”, for breaches by it of its obligations under the North American Free Trade Agreement, referred to as “NAFTA”. The Company’s NAFTA claim, referred to as the “NAFTA Claim”, relates to its investments in the Celgar mill and arises from the treatment of the Celgar mill’s energy generation assets and operations by the Province of British Columbia, primarily through the actions of B.C. Hydro, a provincially owned and controlled enterprise, and the British Columbia Utilities Commission, a provincial government regulatory agency. Our NAFTA Claim is against the Government of Canada, rather than the Province of British Columbia as, under NAFTA, the Canadian federal government is responsible for the actions of its provinces. Our NAFTA Claim alleges that our Celgar mill has received unfair and discriminatory treatment regarding the mill’s ability to purchase and sell energy compared to other pulp mills and entities that generate and sell electricity within the Province of British Columbia. Subsequent to the filing of the NAFTA Notice, our representatives met with representatives of the Government of Canada and the Province of British Columbia to attempt to settle our NAFTA Claim through consultation and negotiation, as required under NAFTA Article 1118. However, no resolution was achieved. As a result, we served a Request for Arbitration on the Government of Canada under NAFTA in order to meet the applicable filing deadline and to preserve and progress our NAFTA Claim. Under our NAFTA Claim, we are seeking approximately C$250 million in damages consisting of past losses of approximately C$19.0 million per year accruing since 2008 and the net present value of projected losses that would result from the ongoing application of discriminatory Provincial policies should the status quo remain

unchanged. Our NAFTA Claim is being instituted under Chapter 11 of NAFTA and will be heard by a tribunal appointed in accordance with Article 1123 of NAFTA. At this time, there can be no assurance whether we will be successful in such claim and we cannot quantify the amount we may recover, if any, under such proceedings if we were successful.

In 2012, as a result of a regular tax field audit for the Stendal mill, German public authorities commenced a preliminary investigation into a past and the current managers of the mill relating to whether certain settlement amounts received by the Stendal mill in 2007, 2010 and 2011 from the main contractor under the Engineering, Procurement and Construction Contract for the construction of the Stendal mill should have reduced the assessment base for the original investment subsidies granted to the mill by German authorities. The payments were made by the contractor to the Stendal mill to settle certain warranty, performance and remediation claims that the Stendal mill made against the contractor after completion of mill construction in 2004. The amounts currently under review aggregate approximately €17.0 million. Investment subsidies received by the Stendal mill were generally based upon a percentage of the assessment base for subsidies of the mill. If the settlement payments received by the Stendal mill result in a reduction of the assessment base for subsidies under applicable German rules there could be a proportionate reduction in the investment subsidies and the difference could be repayable by the Stendal mill. The Stendal mill believes that it has properly recorded the settlement amounts received from the contractor and that the same do not reduce the assessment base for subsidies of the mill. However, at this time, there can be no certainty as to the outcome of the current investigation.

We are also subject to routine litigation incidental to our business. We do not believe that the outcome of such litigation will have a material adverse effect on our business or financial condition.

Not applicable.
