consumer products, with the balance being sold as market pulp. We also purchase papergrade pulp from third parties allowing us to optimize the logistics of our pulp capacity while reducing transportation costs.

We are the largest integrated marketer and manufacturer of uncoated freesheet paper in North America. We have 10 pulp and paper mills (eight in the United States and two in Canada), with an annual paper production capacity of approximately 3.4 million tons of uncoated freesheet paper. Our paper manufacturing operations are supported by 15 converting and distribution operations including a network of 12 plants located offsite of our paper making operations. Also, we have forms manufacturing operations at three offsite converting and distribution operations. Approximately 81% of our paper production capacity is in the U.S. and the remaining 19% is located in Canada.

We produce market pulp in excess of our internal requirements at our three non-integrated pulp mills in Kamloops, Dryden, and Plymouth as well as at our pulp and paper mills in Ashdown, Espanola, Hawesville, Windsor, Marlboro and Nekoosa. We sell approximately 1.6 million metric tons of pulp per year depending on market conditions. Approximately 50% of our trade pulp production capacity is in the U.S., and the remaining 50% is located in Canada.

The table below lists our operating pulp and paper mills and their annual production capacity.

Our Raw Materials

The manufacturing of pulp and paper requires wood fiber, chemicals and energy. We discuss these three major raw materials used in our manufacturing operations below.

Table of Contents

Wood Fiber

United States pulp and paper mills

The fiber used by our pulp and paper mills in the United States is hardwood and softwood, both being readily available in the market from multiple third-party sources. The mills obtain fiber from a variety of sources, depending on their location. These sources include a combination of supply contracts, wood lot management arrangements, advance stumpage purchases and spot market purchases.

Canadian pulp and paper mills

The fiber used at our Windsor pulp and paper mill is hardwood originating from a variety of sources, including purchases on the open market in Canada and the United States, contracts with Quebec wood producers’ marketing boards, public land where we have wood supply allocations and from Domtar’s private lands. The softwood and hardwood fiber for our Espanola pulp and paper mill and the softwood fiber for our Dryden pulp mill, is obtained from third parties, directly or indirectly from public lands and through designated wood supply allocations for the pulp mills. The fiber used at our Kamloops pulp mill is all softwood, originating mostly from third-party sawmilling operations in the southern-interior part of British Columbia.

Cutting rights on public lands related to our pulp and paper mills in Canada represent about 0.9 million cubic meters of softwood and 1.0 million cubic meters of hardwood, for a total of 1.9 million cubic meters of wood per year. Access to harvesting of fiber on public lands in Ontario and Quebec is subject to licenses and review by the respective governmental authorities.

During 2012, the cost of wood fiber relating to our Pulp and Paper segment comprised approximately 20% of the total consolidated cost of sales.

Chemicals

We use various chemical compounds in our pulp and paper manufacturing operations that we purchase, primarily on a central basis, through contracts varying between one and ten years in length to ensure product availability. Most of the contracts have pricing that fluctuates based on prevailing market conditions. For pulp manufacturing, we use numerous chemicals including caustic soda, sodium chlorate, sulfuric acid, lime and peroxide. For paper manufacturing, we also use several chemical products including starch, precipitated calcium carbonate, optical brighteners, dyes and aluminum sulfate.

During 2012, the cost of chemicals relating to our Pulp and Paper segment comprised approximately 13% of the total consolidated cost of sales.

Energy

Our operations consume substantial amounts of fuel including natural gas, fuel oil, coal and biomass, as well as electricity. We purchase substantial portions of the fuel we consume under supply contracts. Under most of these contracts, suppliers are committed to provide quantities within pre-determined ranges that provide us with our needs for a particular type of fuel at a specific facility. Most of these contracts have pricing that fluctuates based on prevailing market conditions. Natural gas, fuel oil, coal and biomass are consumed primarily to produce steam that is used in the manufacturing process and, to a lesser extent, to provide direct heat to be used in the chemical recovery process. About 76% of the total energy required to manufacture our products comes from renewable fuels such as bark and spent cooking liquor. The remainder of the energy comes from purchased fossil fuels such as natural gas, oil and coal.

We own power generating assets, including steam turbines, at all of our integrated pulp and paper mills, as well as hydro assets at three locations: Espanola, Nekoosa and Rothschild. Electricity is primarily used to drive motors and other equipment, as well as provide lighting. Approximately 72% of our electric power requirements are produced internally. We purchase the balance of our power requirements from local utilities.

Table of Contents

During 2012, energy costs relating to our Pulp and Paper segment comprised approximately 6% of the total consolidated cost of sales.

Our Transportation

Transportation of raw materials, wood fiber, chemicals and pulp into our mills is mostly done by rail and trucks although barges are used in certain circumstances. We rely strictly on third parties for the transportation of our pulp and paper products between our mills, converting operations, distribution centers and customers. Our paper products are shipped mostly by truck, and logistics are managed centrally in collaboration with each location. Our pulp is either shipped by vessel, rail or truck. We work with all the major railroads and approximately 300 trucking companies in the United States and Canada. The length of our carrier contracts are generally from one to three years. We pay diesel fuel surcharges which vary depending on market conditions, and the cost of diesel fuel.

During 2012, outbound transportation costs relating to our Pulp and Paper segment comprised approximately 11% of the total consolidated cost of sales.

Our Product Offering and Go-to-Market Strategy

Our uncoated freesheet papers are used for communication and specialty and packaging papers. Communication papers are further categorized into business and commercial printing and publishing applications.

Our business papers include copy and electronic imaging papers, which are used with ink jet and laser printers, photocopiers and plain-paper fax machines, as well as computer papers, preprinted forms and digital papers. These products are primarily for office and home use. Business papers accounted for approximately 45% of our shipments of paper products in 2012.

Our commercial printing and publishing papers include uncoated freesheet papers, such as offset papers and opaques. These uncoated freesheet grades are used in sheet and roll fed offset presses across the spectrum of commercial printing end-uses, including digital printing. Our publishing papers include tradebook and lightweight uncoated papers used primarily in book publishing applications such as textbooks, dictionaries, catalogs, magazines, hard cover novels and financial documents. Design papers, a sub-group of commercial printing and publishing papers, have distinct features of color, brightness and texture and are targeted towards graphic artists, design and advertising agencies, primarily for special brochures and annual reports. These products also include base papers that are converted into finished products, such as envelopes, tablets, business forms and data processing/computer forms. Commercial printing and publishing papers accounted for approximately 40% of our shipments of paper products in 2012.

We also produce paper for several specialty and packaging markets . These products consist primarily of base stock for thermal printing, flexible packaging, food packaging, medical gowns and drapes, sandpapers backing, carbonless printing, labels and other coating and laminating applications. We also manufacture papers for industrial and specialty applications including carrier papers, treated papers, security papers and specialized printing and converting applications. These specialty and packaging papers accounted for approximately 15% of our shipments of paper products in 2012. These grades of papers require a certain amount of innovation and agility in the manufacturing system.

PERSONAL CARE

Our Operations

Our Personal Care business sells and manufactures adult incontinence products and distributes disposable washcloths marketed primarily under the Attends ^® brand name. During 2012, we acquired Attends Europe, a manufacturer and supplier of adult incontinence care products in Northern Europe, consolidating our ownership of the Attends brand on both sides of the Atlantic. We are one of the leading suppliers of adult incontinence products sold into North America and Northern Europe, selling to hospitals (acute care) and nursing homes (long-term care) and we have a growing presence in the homecare and retail channels.

We operate two manufacturing facilities, with each having the ability to produce multiple product categories. We also have a research and development facility and production lines which manufacture high quality airlaid and ultrathin laminated absorbent cores.

Attends operates in the United States and in Europe:

Our Industry Dynamics

Aging population

We compete in an industry with fundamental drivers for long-term growth. The aging population suggests that adult incontinence will become much more prevalent over the next several decades, as baby boomers enter their senior years and medical advances continue to extend the average lifespan. As an example, the National Association for Continence (“NAFC”) estimates that 10,000 Americans are turning 65 years old every day, or 3.65 million people per year. By the year 2030, approximately 71 million Americans are estimated to be 65 years old or older, representing over 20% of the U.S. population. It is estimated that approximately 5% of the world population, or 340 million individuals, is incontinent. After age 65, nearly one in three people are estimated to suffer from incontinence.

Increased healthcare spending

We are expected to benefit from the overall increase in national healthcare spending, which is due to an aging population and is aided by the recent federal legislative expansion of health insurance coverage, in the United States. Spending will likely increase at an even faster rate as health insurance coverage is expanded and the number of insured patients with the improved ability to access healthcare products and services increases. Growing healthcare expenditures are expected to spur an increase in spending within each of the channels served by Attends.

Our Raw Materials

The primary raw materials used in our manufacturing process are nonwovens, fluff pulp, super absorbent polymers, polypropylene film, elastics, adhesives and packaging materials that are purchased on a central basis with contracts varying between one and five years. Most contracts have prices that fluctuate based on prevailing market conditions.

Our Product Offering and Go-to-Market Strategy

Our products, which include branded and private label briefs, protective underwear, underpads, pads and washcloths, are available in a variety of sizes, as well as with differing performance levels and product attributes. Our broad product portfolio covers most price points across each product category.

12

Table of Contents

We serve four channels: acute care, long-term care, homecare, and retail. Through the utilization of our flexible production platform, manufacturing expertise and efficient supply chain management, we are able to provide a complete and high-quality line of branded and unbranded products to customers across all channels. We maintain a direct sales organization in the United States, Canada and nine Northern European countries.

Our Product Development

We currently offer a comprehensive, full suite of products, and we continue to focus on product development to produce even more effective products for our customers. We continue to explore materials and processes that will allow us to manufacture products that absorb wetness quickly, while providing industry leading skin-dryness and superior containment.

OUR STRATEGIC INITIATIVES AND FINANCIAL PRIORITIES

As a leading innovative fiber-based technology company, we strive to be the supplier of choice for our customers, to be a core investment for our shareholders and to be recognized as an industry leader in sustainability. We have three unwavering business objectives: (1) to grow and find ways to become less vulnerable to the secular decline in communication paper demand, (2) to reduce volatility in our earnings profile by increasing the visibility and predictability of our cash flows, and (3) to create value over time by ensuring that we maximize the strategic and operational use of our capital.

To achieve these goals, we have established the following business strategies:

Perform: Drive performance in everything we do, focusing on customers, costs and cash. We are determined to operate our assets efficiently and to ensure we balance our production with our customer demand in papers. To generate cash flow, we are focused on assigning our capital expenditures effectively and minimizing working capital requirements. We apply prudent financial management policies to retain the flexibility needed to successfully execute on our strategic roadmap.

Grow: To counteract the secular demand decline in our communication paper products and sustain the success of our company, we believe that we must leverage our core competencies and expertise as operators of large scale operations in fiber sourcing and in the marketing, manufacturing and distribution of fiber-based products. We are focused on optimizing and expanding our operations in markets with positive demand dynamics through the repurposing of assets, through investments to organically grow or through strategic acquisitions.

Break Out: Through agility and innovation, move from a paper to a fiber-centric organization by seeking opportunities to break out from traditional pulp and paper making. We continue to explore opportunities to invest in innovative fiber-based technologies to bring our business in new directions and leverage our expertise and our assets to extract the maximum value for the wood fiber we consume in our operations.

Grow our line of environmentally and ethically responsible products: We believe we are delivering best-in-class service to customers through a broad range of certified products. The development of EarthChoice ^® , our line of environmentally and socially responsible paper, is providing a platform upon which to expand our offering to customers. This product line is supported by leading environmental groups and offers customers the solutions and peace of mind through the use of a combination of Forest Stewardship Council ^® (FSC ^® ) virgin fiber and recycled fiber.

Operate in a responsible way: We try to make a positive difference every day by pursuing sustainable growth, valuing relationships, and responsibly managing our resources. We care for our customers, end-users and stakeholders in the communities where we operate, all seeking assurances that resources are managed in a sustainable manner. We strive to provide these assurances by certifying our distribution and manufacturing operations and measuring our performance against internationally recognized benchmarks. We are committed to the responsible use of forest resources across our operations and we are enrolled in programs and initiatives to encourage landowners engaged towards certification to improve their market access and increase their revenue opportunities.

OUR COMPETITION

The markets in which our businesses operate are highly competitive with well-established domestic and foreign manufacturers.

In the paper business, our paper production does not rely on proprietary processes or formulas, except in highly specialized papers or customized products. In order to gain market share in uncoated freesheet, we compete primarily on the basis of product quality, breadth of offering, service solutions and competitively priced paper products. We seek product differentiation through an extensive offering of high quality FSC-certified paper products. While we have a leading position in the North American uncoated freesheet market, we also compete with other paper grades, including coated freesheet, and with electronic transmission and document storage alternatives. As the use of these alternative products continues to grow, we continue to see a decrease in the overall demand for paper products or shifts from one type of paper to another. All of our pulp and paper manufacturing facilities are located in the United States or in Canada where we sell 89% of our products. The five largest manufacturers of uncoated freesheet papers in North America represent approximately 80% of the total production capacity. On a global basis, there are hundreds of manufacturers that produce and sell uncoated freesheet papers. The level of competitive pressures from foreign producers in the North American market is highly dependent upon exchange rates, including the rate between the U.S. dollar and the Euro as well as the U.S. dollar and the Brazilian real.

The market pulp we sell is either fluff, softwood or hardwood pulp. The pulp market is highly fragmented with many manufacturers competing worldwide. Competition is primarily on the basis of access to low-cost wood fiber, product quality and competitively priced pulp products. The fluff pulp we sell is used in absorbent products, incontinence products, diapers and feminine hygiene products. The softwood and hardwood pulp we sell is primarily slow growth northern bleached softwood and hardwood kraft, and we produce specialty engineered pulp grades with a pre-determined mix of wood species. Our hardwood and softwood pulps are sold to customers who make a variety of products for specialty paper, packaging, tissue and industrial applications, and customers who make printing and writing grades. We also seek product differentiation through the certification of our pulp mills to the FSC chain-of-custody standard and the procurement of FSC-certified virgin fiber. All of our market pulp production capacity is located in the United States or in Canada, and we sell 57% of our pulp to other countries.

In the adult incontinence business in North America, the top 5 manufacturers supply approximately 90% of the market share and have done so for at least the last 10 years. Competition is along the line of four major product categories—protective underwear, light pads, briefs and underpads with customers split between retail and institutional channels. The retail channel has the majority of sales concentrated in mass marketers and drug stores. The institutional channel includes extended care (long term care and homecare) and acute care facilities. In the adult incontinence business in Europe, we compete in the Western, Northern and Central Europe markets where the top 5 manufacturers supply approximately 80% to the healthcare channel and 99% of the retail channel. Competition is along the line of four major product categories: pads, pull-ons, briefs and underpads, with customers mostly split between mass retail, prescription and closed contract. The mass retail market is more fragmented than in North American markets with a mix of larger chains and smaller players. Approximately 70% of institutional and homecare expenditures are funded by local governments in Western Europe. In the adult incontinence business, the principal methods and elements of competition include brand recognition and loyalty, product innovation, quality and performance, price and marketing and distribution capabilities.

OUR EMPLOYEES

We have over 9,300 employees, of which approximately 63% are employed in the United States, 31% in Canada, 5% in Europe and 1% in Asia. Approximately 53% of our employees are covered by collective bargaining agreements, generally on a facility-by-facility basis. Certain agreements covering approximately 674 employees will expire in 2013 and others will expire between 2014 and 2017.

OUR APPROACH TO SUSTAINABILITY

Domtar delivers a higher, lasting value to our customers, employees, shareholders and communities by viewing our business decisions within the larger context of sustainability. As a renewable fiber-based company,

14

Table of Contents

we take the long-term view on managing natural resources for the future. We prize efficiency in everything we do. We strive to minimize waste and encourage recycling. We have the highest standards for ethical conduct, for caring about the health and safety of each other, and for maintaining the environmental quality in the communities where we live and work. We value the partnerships we have formed with non-governmental organizations and believe they make us a better company, even if we do not always agree on every issue. We pay attention to being agile to respond to new opportunities, and we are focused in order to turn innovation into value creation. By embracing sustainability as our operating philosophy, we seek to internalize the fact that the choices we have and the impact of the decisions we make on our stakeholders are all interconnected. Further, we believe that our business and the people and communities who depend upon us are better served as we weave this focus on sustainability into the things we do.

Domtar effects this commitment to sustainability at every level and every location across the company. With the support of the Board of Directors, our Management Committee empowers senior managers from manufacturing, technology, finance, sales and marketing and corporate staff functions to regularly come together and establish key sustainability performance metrics, and to routinely assess and report on progress. In 2011, Domtar decided to establish a new, vice-president position to help lead this effort, allowing the company’s organizational structure to better reflect the priority focus the company places on sustainable performance. At the same time, recognizing that the promise of sustainability is only achieved if it is woven into the fiber of an organization, Domtar is committed to establishing EarthChoice Ambassadors—sustainability leaders and advocates—in every one of the company’s locations. We believe that weaving sustainability into our business positions Domtar for the future.

OUR ENVIRONMENTAL CHALLENGES

Our business is subject to a wide range of general and industry-specific laws and regulations in the United States and other countries were we have operations, relating to the protection of the environment, including those governing harvesting, air emissions, climate change, waste water discharges, the storage, management and disposal of hazardous substances and wastes, contaminated sites, landfill operation and closure obligations and health and safety matters. Compliance with these laws and regulations is a significant factor in the operation of our business. We may encounter situations in which our operations fail to maintain full compliance with applicable environmental requirements, possibly leading to civil or criminal fines, penalties or enforcement actions, including those that could result in governmental or judicial orders that stop or interrupt our operations or require us to take corrective measures at substantial costs, such as the installation of additional pollution control equipment or other remedial actions.

Compliance with environmental laws and regulations involves capital expenditures as well as additional operating costs. For example, in December 2012, the United States Environmental Protection Agency proposed a new set of standards related to all industrial boilers, including those present at pulp and paper mills.
