President’s Comments

Mr. Jimmy S.H. Lee, President and Chairman, stated: “2014 was a transformative year for us as:

Mr. Lee continued: “For the fourth quarter of 2014, our Operating EBITDA increased by approximately 162% to $71.3 million from $27.2 million in the same quarter of 2013, primarily as a result of the strengthening of the U.S. dollar relative to the Canadian dollar and the Euro, lower per unit fiber costs and lower scheduled maintenance downtime. Compared to the third quarter of 2014, our Operating EBITDA in the fourth quarter of 2014 increased by approximately 5% from $67.6 million, primarily as a result of the strengthening of the U.S. dollar.

In 2014, Operating EBITDA increased by 117% to $239.8 million from $110.3 million in 2013, primarily as a result of higher pulp prices, lower per unit fiber costs, the strengthening of the U.S. dollar versus the Euro and Canadian dollar and higher energy sales volumes.”

Mr. Lee added: “Our mills generally performed well in the fourth quarter and throughout 2014. In 2014, we achieved a new pulp production record, led by a record production year at our Stendal mill and a near record year at our Rosenthal mill. In the current quarter, pulp sales volumes increased by 1% from the same period of 2013 but declined by 7%, compared to the third quarter of 2014 due to year-end shipping limitations. In 2014, we had record pulp sales volumes which increased by 3% over 2013.”

Mr. Lee continued: “In the current quarter, energy production increased by 8%, compared to the same period of 2013. In addition, our Rosenthal mill’s new tall oil plant was completed on time and budget at the end of the fourth quarter of 2014 and will contribute to our by-product revenues.”

Mr. Lee stated: “List pulp prices were essentially flat in the fourth quarter of 2014 due to steady demand in Europe and China. At the end of 2014, list pulp prices in Europe were approximately $935 per ADMT, while list prices in North America and China were approximately $1,020 and $700 per ADMT, respectively. At year end, world producer inventories of NBSK pulp were at about 31 days’ supply. We expect steady NBSK demand, driven by customer inventories at normal to low levels and new tissue machines coming online in 2015.”

Mr. Lee continued: “Overall, per unit fiber costs were approximately 14% lower in the fourth quarter of 2014, compared to the last quarter of 2013, as a result of lower per unit costs in our German fiber supply markets and the strengthening of the U.S. dollar versus the Euro and the Canadian dollar. Fourth quarter 2014 per unit fiber costs were down 1% from the prior quarter as the strengthening of the U.S. dollar offset an increase in per unit costs. We currently expect our overall per unit fiber costs to be generally flat for the next quarter of 2015, largely as a result of the continuing strengthening of the U.S. dollar versus the Euro and Canadian dollar, offsetting small expected per unit cost increases.”

Mr. Lee concluded: “As our operating costs are primarily incurred in Euros and Canadian dollars and our principal product, NBSK pulp, is quoted in U.S. dollars, our business and operating margins materially benefit from the current strengthening of the U.S. dollar. Our energy and chemical sales are made in local currencies and as a result decline in U.S. dollar terms when the U.S. dollar strengthens. Going forward, while we will continue to benefit from a stronger U.S. dollar, it will be partially offset as in 2015 the rapid strengthening of the U.S. dollar has put downward pressure on pulp prices as a stronger U.S. dollar increases costs to our European and Asian customers.”

Three Months Ended December 31, 2014 Compared to Three Months Ended December 31, 2013

Total revenues for the fourth quarter of 2014 and 2013 were $282.6 million. In the fourth quarter of 2014, pulp revenues increased marginally to $258.7 million from $258.5 million in the comparative quarter of 2013 while energy and chemical revenues decreased marginally to $23.9 million from $24.1 million in the same quarter last year.

Pulp production increased by approximately 2% to 373,681 ADMTs in the current quarter from 364,798 ADMTs in the same quarter of 2013, primarily as a result of lower downtime. In the current quarter, we had two days of scheduled maintenance downtime at our Stendal mill, or approximately 3,800 ADMTs, which adversely impacted Operating EBITDA by approximately $2.9 million, comprised of approximately $2.3 million in direct out-of-pocket expenses and the balance for reduced production. Many of our competitors that report their financial results using “IFRS” capitalize their direct costs of maintenance shutdowns. Going forward, we have ten days of scheduled maintenance downtime in the first quarter of 2015.

Pulp sales volumes increased to 361,302 ADMTs in the current quarter from 358,583 ADMTs in the comparative quarter of 2013, primarily due to continuing steady demand.

Average pulp sales realizations decreased to $709 per ADMT from approximately $713 per ADMT in the same quarter last year primarily due to our sales mix, as higher list prices in Europe were offset by lower prices in China.

Costs and expenses in the fourth quarter of 2014 decreased by approximately 16% to $230.3 million from $275.8 million in the comparative period of 2013, primarily due to the overall impact on costs of the stronger U.S. dollar, lower per unit fiber costs and less scheduled maintenance downtime.

Transportation costs decreased to $20.1 million in the current quarter of 2014 from $22.2 million in the comparative quarter of 2013, primarily due to the stronger U.S. dollar.

On average, our overall per unit fiber costs in the current quarter decreased by approximately 14% from the same period in 2013, as a result of both a stronger U.S. dollar and lower per unit fiber costs in our German fiber supply markets. Per unit fiber costs in Germany decreased by approximately 17% in the fourth quarter of 2014, compared to the same quarter of 2013. Per unit fiber costs at our Celgar mill decreased by approximately 4% in the fourth quarter of 2014 versus the same quarter of 2013 as a result of the stronger U.S. dollar.

In the fourth quarter of 2014, our operating income increased to $52.3 million from $6.9 million in the comparative quarter of 2013, primarily due to the strengthening of the U.S. dollar, lower per unit fiber costs and less scheduled maintenance downtime.

Interest expense decreased to $15.4 million in the fourth quarter of 2014 from $17.4 million in the comparative quarter of 2013, primarily as a result of lower indebtedness.

In the fourth quarter of 2014, Operating EBITDA increased by approximately 162% to $71.3 million from $27.2 million in the fourth quarter of 2013. Operating EBITDA is defined as operating income (loss) plus depreciation and amortization and non-recurring capital asset impairment charges. Operating EBITDA has significant limitations as an analytical tool and should not be considered in isolation or as a substitute for our results as reported under GAAP. See page 4 of the financial tables included in the press release for a reconciliation of net income (loss) attributable to common shareholders to Operating EBITDA.

In the fourth quarter of 2014, we effected the Refinancing, the net proceeds of which, along with cash on hand and drawdowns from our revolving credit facilities, was used to repay and discharge our old 2017 9.5% senior notes and Stendal bank credit facilities. We recorded a loss of $28.5 million on the settlement of such debt.

Page 6

We recorded a non-cash derivative gain of $2.3 million on the mark to market adjustment of our Stendal mill’s interest rate derivative in the fourth quarter of 2014, compared to a net derivative gain of $3.8 million in the same quarter of last year.

During the current quarter and the same quarter of 2013, we recorded an income tax expense of $6.0 million.

We reported net income attributable to common shareholders of $3.2 million, or $0.05 per basic and diluted share, for the fourth quarter of 2014 after giving effect to the $28.5 million loss on the settlement of debt resulting from the Refinancing. In the fourth quarter of 2013, the net loss attributable to common shareholders was $9.8 million, or $0.18 per basic and diluted share.

Year Ended December 31, 2014 Compared to Year Ended December 31, 2013

Total revenues in 2014 increased by approximately 8% to $1,175.1 million from $1,088.4 million in 2013, primarily due to higher pulp revenues and higher energy and chemical revenues.

Pulp revenues in 2014 increased by approximately 8% to $1,073.6 million from $996.2 million in 2013, due to higher pulp price realizations and higher sales volumes.

Energy and chemical revenues increased by approximately 10% to $101.5 million in 2014 from $92.2 million in 2013, primarily because of record energy sales volumes resulting from Project Blue Mill coming online at our Stendal mill at the end of 2013.

Pulp production increased by approximately 3% to 1,485,011 ADMTs in 2014 from 1,444,475 ADMTs in 2013. We had an aggregate of 24 days (approximately 31,600 ADMTs) of scheduled maintenance downtime at our mills in 2014, compared to 33 days in 2013.

Pulp sales volumes increased by approximately 3% to 1,486,356 ADMTs in 2014 from 1,440,147 ADMTs in 2013, primarily due to generally steady demand throughout 2014.

Average pulp sales realizations increased by approximately 5% to $715 per ADMT in 2014 from approximately $683 per ADMT last year, primarily due to higher list prices.

Costs and expenses in 2014 decreased by approximately 4% to $1,013.3 million from $1,056.7 million in 2013, primarily due to lower per unit fiber costs and the overall impact on costs of the stronger U.S. dollar.

Transportation costs decreased to $88.6 million in 2014 from $90.0 million in 2013.

On average, our overall per unit fiber costs in 2014 decreased by approximately 7% from 2013, primarily as a result of lower average fiber costs in the markets from which our mills source their fiber and the strengthening of the U.S. dollar versus the Canadian dollar. Our per unit fiber costs for our Celgar mill decreased during 2014 compared to last year due to strong sawmill activity in the region. Our per unit fiber costs at our German mills declined due to sawmills running at high rates, a stronger supply of logs and lower demand from pellet producers and board manufacturers.

Page 7

In 2014, our operating income increased to $161.8 million from $31.7 million in 2013, primarily due to higher pulp price realizations, lower per unit fiber costs, the strengthening of the U.S. dollar and record energy sales volumes.

Interest expense in 2014 decreased to $67.5 million from $69.2 million in 2013, primarily due to lower indebtedness.

The noncontrolling shareholder’s interest in the Stendal mill’s net income in 2014 was $7.8 million, compared to $0.6 million in the prior year.

In 2014, Operating EBITDA increased by 117% to $239.8 million from $110.3 million in 2013. See page 4 of the financial tables included in the press release for a reconciliation of net income (loss) attributable to common shareholders to Operating EBITDA.

In 2014, we recorded a non-cash derivative gain of $11.5 million on the mark to market adjustment of our Stendal mill’s interest rate derivative, compared to a net derivative gain of $19.7 million last year.

During 2014, we recorded a net gain on the settlement of debt of $3.4 million, which reflected a gain of $31.9 million on our acquisition of all of the shareholder loans of the former noncontrolling shareholder in Stendal, in large part offset by a loss of $28.5 million on the settlement of debt resulting from the Refinancing.

During 2014, we recorded a net income tax benefit of $16.8 million, compared to a net income tax expense of $9.2 million in 2013, primarily due to the recognition of income tax loss carry-forwards associated with our Stendal mill.

We had net income attributable to common shareholders of $113.2 million, or $1.82 per basic and $1.81 per diluted share, in 2014. In 2013, the net loss attributable to common shareholders was $26.4 million, or $0.47 per basic and diluted share.

COMPUTATION OF OPERATING EBITDA

(Unaudited)

(In thousands)

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), including financing costs and the effect of derivative instruments. Operating EBITDA is not a measure of financial performance under 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. The following tables set forth the net income (loss) attributable to common shareholders to Operating EBITDA:
