Rising up the Value Chain through Bio-Refinery Strategy We are a leader among paper and forest products manufacturers in pursuing a full bio-refinery strategy We harness value from all aspects of the biomass we process by generating electricity and chemicals The market continues to turn to carbon-neutral and renewable sources for power and chemicals Energy and chemical production is capital intensive, but we have already made these investments – this production requires limited incremental operating expenses, which makes it highly profitable Green electricity and chemical revenue… a significant and growing part of our business CAGR: 5.0% CAGR: 9.4% CAGR: 5.9%

Value Creation through Deep Focus on Wood Markets We have deep competence in wood procurement We are market leaders in our local markets for industrial wood, particularly in Germany We are innovators in the design and implementation of new wood procurement methods New roundwood railcar fleet 200 new, custom designed, high volume cars delivered in 2016 >50% more wood volume per 540m train Suitable for pulpwood and sawlogs; currently focused on imports from Baltic states New wood procurement organization with Mondi - wood2M Joint procurement of wood from non-traditional regions Expansion of reach and imports of pulpwood and sawlogs into Germany Wood is a core competency of Mercer… Expansion in the wood market is a natural fit and key element of EBITDA stability

Our Growing Import Reach for Wood Baltic port expansion Our log port at Rostock Germany was recently expanded; enables greater imports from Baltic states, Scandinavia and UK Rail logistics expansion Acquisition of rail sidings Construction of new railway unloading facility at Rosenthal Construction of new automated chip unloading and reclaim system at Rosenthal €7.1 million project completed in late 2015 Project reduces personnel, equipment costs and improves pulp yield

Small log / waste wood utilization project in British Columbia BC wood harvest process historically plagued with wood utilization inefficiencies - “Waste” that has the potential to become pulp mill quality wood chips Timber harvest typically managed by lumber-focused sawmillers which creates a tendency for pulp-suitable wood to be left in the forest Wood Utilization Strategy Mercer’s new subsidiary, Arbor Sentinel, is dedicated to this business. It’s first order of business was the custom design and manufacture of new chipping and transportation equipment for delivery of this wood to Celgar Mitigates impacts of BC allowable annual cut reductions elsewhere in the province and supply risk introduced as a result of Softwood Lumber Agreement expiry

Steady Focus on Cost Reduction Fibre costs are consolidated for Celgar, Rosenthal and Stendal and converted using quarterly average FX rates Transportation costs are gross for all mills

The NBSK Market

NBSK in the Global Pulp Market NBSK generally attracts a price premium relative to other kraft pulps (1) Source: PPPC (2014A); some numbers may not add due to rounding Tissue NBSK End Uses Northern Bleached Softwood Kraft (“NBSK”) is produced from spruce, pine, fir and cedar grown primarily in the forests of Canada, Northern Europe and North-Central Russia: Specialties (14 mm ADMTs)

Fiber Characteristics Long, slender, thin-walled fibers Better softness compared to SBSK and Radiata Better strength Fiber Advantages Provides structural integrity for the fiber network due to length and fineness Each NBSK fiber has three times more bonding strength than a Bleached Eucalyptus Kraft (BEK) fiber Gives strength and resistance to strain, tear and fracture in both dry and wet states Advantageous for end products and for runnability of modern, high-speed paper machines Demand Fundamentals – NBSK Fiber Importance (1) Source: FPInnovations (September 8, 2014, prepared for Mercer International) (2) Source: FPInnovations (2014); based on averages Pulp Fiber Bonding (1) Softwood Fiber Hardwood Fiber Fiber-to-Fiber Bonding Performance characteristics of the NBSK fiber give it a unique competitive advantage Fiber Characteristics Comparison (2) NBSK SBSK Radiata BEK Fiber Diameter (μm) 25 35 29 11 Cell Wall Thickness (μm) 2.1 3.5 2.3 1.7 Fiber Length (mm) 2.38 2.46 2.24 0.75

Demand Fundamentals – NBSK Fiber Importance (Cont’d) Tissues / Towels Printing & Writing Grades Conclusions NBSK is a key component for products requiring strength Proportionally more NBSK is used in tissues, towels and specialities than in printing & writing papers (1) Source: FPInnovations (November 30, 2015, prepared for Mercer International) NBSK’s strength attributes make it a necessary input for tissue and specialty products Specialties

Demand Fundamentals – Changes to NBSK End Uses NBSK Demand Changes Increased NBSK demand for tissue / specialty products has more than offset decreased NBSK demand for traditional printing & writing grades (digital substitution) Significant growth in global tissue demand is a major contributing factor and is expected to continue 61% 22% 17% 30% 30% 40% P&W: (6%) Tissue: +10% Specialty & Other: +4% CAGR Source: PPPC (November 2014) for NBSK Demand; Brian McClay for NBSK End Uses (November 2014) Source: Brian McClay (October 2016); some numbers may not add due to rounding Mainly driven by tissue and specialty growth, aggregate NBSK demand has been growing

Supply Fundamentals – China’s Decreasing Pulp Supply Source: RISI (press releases from December 2, 2015, June 26, 2015, January 9, 2015, November 26, 2014, August 22, 2014 and July 24, 2014; PPI Asia Report dated May 9, 2014; and other disclosures) Source: RISI World Pulp Monthly reports Shutdown of “Old China” Significant pulp and paper capacity closures to date and to come Implementing pollution, water and energy constraints in order to stay operating Many old mills use straw and/or bamboo as feedstocks Impact on Global Markets New mills in China use wood-based pulps With limited domestic supply, imports are required New hardwood supply from Latin America has been absorbed better than expected due to strong demand in China, as well as the shutdowns of the old Chinese mills Chinese Government Mandated Closure of “Old China” Capacity (1) 2005-2009: 6.5 mm tonnes per year over 5 years 2011: 8.31 mm tonnes 2012: 10.57 mm tonnes 2013: 8.31 mm tonnes 2014: 5.47 mm tonnes 2015E YTD April: 3.37 mm tonnes (not yet finalized) We believe that the recent decrease in the NBSK-BEK price spread is mostly attributable to greater than expected strength in BEK markets, not weakness in NBSK markets

Softwood Markets We believe that new NBSK capacity announcements are being motivated by: Demand growth expectations Capacity decreases Capacity decreases could be coming from: Old, high cost mills approaching end of life conditions Mill conversions to dissolving pulp Integration of market pulp (new paper machine at Mondi Štĕtí, Czech Republic: volume impact unknown) Hardwood Markets Rapidly increasing supply of hardwood is being absorbed in markets like China, where domestic supply is declining and demand is increasing Supply Fundamentals – Net Capacity Change Analysis (1) Source: Hawkins Wright (August 2016) We believe this increased NBSK capacity is consistent with growing demand

Appendix B Reconciliation of Net Income to Operating EBITDA

Reconciling Net Income to Operating EBITDA in US$ millions 2013 2014 2015 Q3 2015 Q3 2016 Net Income (Loss) Attributable to Common Shareholders ($26.4)$113.2$75.5 $23.8$11.9 Add: Net Income Attributable to Non-Controlling Interest$0.6$7.8--- Add: Income Tax Provision (Benefit) $9.2($16.8)$29.4 $6.6$5.1 Add: Interest Expense$69.2$67.5$53.9 $13.3$12.8 Add: Loss (Gain) on Derivative Instruments($19.7)($11.5)$0.9 $0.3($0.0) Add: Other Expense (Income) ($1.2)$1.6$5.9 $0.1 $0.0 Operating Income$31.7$161.8$165.7 $44.0$29.8 Add: Depreciation and Amortization$78.6$78.0$68.3 $17.1$18.0 Operating EBITDA$110.3$239.8$234.0 $61.1$47.9 (2) (1) (1) Note: For other reconciliations of Net Income (Loss) to Operating EBITDA in periods not shown here, please refer to that period’s respective Form 10-Q or 10-K, which can be found on our website (www.mercerint.com) Note: Some numbers may not add due to rounding Quarterly data represents 3 months ended September 30 Completed acquisition of minority interest in September 2014 Includes debt settlement gain of $31.9 million related to the acquisition of the minority shareholder debt at Stendal and debt settlement loss of $20.5 million related to the 2017 Senior Notes Operating EBITDA is defined as operating income (loss) plus depreciation and amortization and non-recurring capital asset impairment charges. Management uses Operating EBITDA as a benchmark measurement of its own operating results, and as a benchmark relative to its competitors. Management considers it to be a meaningful supplement to operating income (loss) as a performance measure primarily because depreciation expense and non-recurring capital asset impairment charges are not an actual cash cost, and depreciation expense varies widely from company to company in a manner that management considers largely independent of the underlying cost efficiency of their operating facilities. In addition, we believe Operating EBITDA is commonly used by securities analysts, investors and other interested parties to evaluate our financial performance. Operating EBITDA does not reflect the impact of a number of items that affect our net income (loss) attributable to common shareholders, including financing costs and the effect of derivative instruments. Operating EBITDA is not a measure of financial performance under the accounting principles generally accepted in the United States of America (“GAAP”), and should not be considered as an alternative to net income (loss) or income (loss) from operations as a measure of performance, nor as an alternative to net cash from operating activities as a measure of liquidity. Operating EBITDA has significant limitations as an analytical tool, and should not be considered in isolation, or as a substitute for analysis of our results as reported under GAAP. Operating EBITDA should only be considered as a supplemental performance measure and should not be considered as a measure of liquidity or cash available to us to invest in the growth of our business. Because all companies do not calculate Operating EBITDA in the same manner, Operating EBITDA as calculated by us may differ from Operating EBITDA or EBITDA as calculated by other companies. We compensate for these limitations by using Operating EBITDA as a supplemental measure of our performance and by relying primarily on our GAAP financial statements. (3)
