For Immediate Release

MERCER INTERNATIONAL INC. REPORTS 2016 THIRD QUARTER RESULTS

ANNOUNCES QUARTERLY CASH DIVIDEND OF $0.115 PER SHARE

NEW YORK, NY, October 27, 2016 - Mercer International Inc. (Nasdaq: MERC, TSX: MRI.U) today reported results for the third quarter ended September 30, 2016. Operating EBITDA* in the third quarter of 2016 declined to $47.9 million from $61.1 million in the third quarter of 2015, primarily due to lower pulp sales realizations and sales volumes, partially offset by lower fiber prices, but increased from $34.7 million in the prior quarter of 2016.

For the third quarter of 2016, we had net income of $11.9 million, or $0.18 per basic and diluted share, compared to net income of $23.8 million, or $0.37 per basic and diluted share, in the third quarter of 2015 and a net loss of $4.2 million, or $0.07 per basic and diluted share, in the prior quarter of 2016.

Summary Financial Highlights

* Operating EBITDA is not a measure of financial performance under accounting principles generally accepted in the United States (“GAAP”) and should not be considered in isolation or as a substitute for analysis of our results as reported under GAAP. See page 4 of the financial tables included in this press release for a reconciliation of net income to Operating EBITDA.

President’s Comments

Mr. David M. Gandossi, Chief Executive Officer, stated:

Mr. Gandossi continued: “During the current quarter, we continued to focus on high return projects to improve our operational efficiencies, including projects that improve our operational reliability and de-bottleneck certain processes. We are also moving forward with certain high value fiber logistics projects in Germany which, we hope, will further reduce our fiber costs and exposure to fiber supply risks.”

Mr. Gandossi concluded: “Currently, the NBSK pulp market is generally balanced, with world producer inventories at about 30 days’ supply. Looking forward to the fourth quarter of 2016, we currently expect overall steady pulp demand and stable pricing in Europe and China.”

Three Months Ended September 30, 2016 Compared to Three Months Ended September 30, 2015

Total revenues for the three months ended September 30, 2016 decreased by approximately 12% to $237.9 million from $270.9 million in the same quarter of 2015, primarily due to lower pulp revenues.

Pulp revenues in the third quarter of 2016 decreased by approximately 13% to $215.8 million from $249.1 million in the same quarter of 2015, due to lower sales volumes and lower pulp sales realizations.

Energy and chemical revenues in the third quarter of 2016 increased marginally to $22.1 million from $21.8 million in the same quarter of 2015, primarily due to higher chemical sales.

Pulp production decreased by approximately 2% to 361,800 ADMTs in the current quarter from 369,473 ADMTs in the same quarter of 2015. In the current quarter, we had an aggregate of 10 days (approximately 10,200 ADMTs) of annual maintenance downtime at our Rosenthal mill compared to 11 days (approximately 11,100 ADMTs) at such mill in the comparative quarter of 2015.

We estimate that annual maintenance downtime in the current quarter adversely impacted our Operating EBITDA by approximately $6.7 million, comprised of approximately $5.0 million in direct out-of-pocket expenses and the balance in reduced production. Many of our competitors that report their financial results using International Financial Reporting Standards (“IFRS”) capitalize their direct costs of maintenance downtime.

Pulp sales volumes decreased by approximately 8% to 359,791 ADMTs in the current quarter from 390,216 ADMTs in the same quarter of 2015, primarily due to lower sales to China as our Stendal mill allocated certain volumes to Europe as a result of better realizations, managed inventories ahead of its fourth quarter scheduled maintenance downtime and, in the comparative quarter, had near record sales.

In the current quarter of 2016, list prices for NBSK pulp in Europe and China declined from the same quarter of 2015, largely as a result of the strong dollar. Average list prices for NBSK pulp in Europe were approximately $810 per ADMT in the third quarter of 2016, compared to approximately $843 per ADMT in the same quarter of 2015. Average list prices for NBSK pulp in China and North America were approximately $595 per ADMT and $998 per ADMT, respectively, in the third quarter of 2016, compared to approximately $638 per ADMT and $967 per ADMT, respectively, in the same quarter of 2015.

Page 4

Average pulp sales realizations decreased by approximately 6% to $593 per ADMT in the third quarter of 2016 from approximately $632 per ADMT in the same quarter last year, primarily due to lower list prices largely resulting from the overall strength of the dollar which increases the cost of pulp for our customers primarily in Europe and China.

The impact of changes in the exchange rates for the dollar to the euro and the Canadian dollar on our dollar-denominated cash balances and receivables held at the mills reduced our operating income by $5.1 million when compared to the same quarter of the prior year.

Costs and expenses in the current quarter decreased by approximately 8% to $208.1 million from $226.9 million in the third quarter of 2015, primarily due to lower pulp sales volumes and fiber prices.

In the third quarter of 2016, operating depreciation and amortization was $17.9 million, compared to $16.9 million in the same quarter of 2015.

Selling, general and administrative expenses decreased to $10.1 million in the third quarter of 2016 from $12.5 million in the same quarter of 2015 due to lower costs associated with our completed NAFTA claim, for which we are awaiting a decision.

Transportation costs decreased by approximately 13% to $17.5 million in the current quarter from $20.0 million in the same quarter of 2015 primarily due to lower pulp sales volumes.

On average, in the current quarter overall fiber prices decreased by approximately 7% from the same quarter of 2015, primarily as a result of a balanced wood market and strong sawmilling activity in both Germany and the Celgar mill’s fiber basket. In the current quarter, in euro terms, average fiber prices in Germany were approximately 10% lower than the comparative quarter. In the current quarter, in Canadian dollar terms, average fiber prices for our Celgar mill were marginally lower than the comparative quarter.

In the third quarter of 2016, our operating income decreased by approximately 32% to $29.8 million from $44.0 million in the same quarter of 2015, primarily due to lower pulp sales realizations and sales volumes, partially offset by lower fiber prices.

Interest expense in the current quarter decreased to $12.8 million from $13.3 million in the same quarter of 2015, primarily as a result of lower indebtedness.

During the third quarter of 2016, income tax expense decreased to $5.1 million from $6.6 million in the same quarter of 2015 due to lower taxable income for our German subsidiaries.

For the third quarter of 2016, we had net income of $11.9 million, or $0.18 per basic and diluted share, compared to net income of $23.8 million, or $0.37 per basic and diluted share, in the same quarter of 2015.

In the third quarter of 2016, Operating EBITDA decreased by approximately 22% to $47.9 million from $61.1 million in the same quarter of 2015, primarily due to lower pulp sales realizations and sales volumes, partially offset by lower fiber prices.

Nine Months Ended September 30, 2016 Compared to Nine Months Ended September 30, 2015

Total revenues for the nine months ended September 30, 2016 decreased by approximately 11% to $709.9 million from $795.4 million in the same period of 2015, primarily due to lower pulp revenues.

Pulp revenues in the nine months ended September 30, 2016 decreased by approximately 12% to $644.5 million from $729.9 million in the same period of 2015 due to lower pulp sales realizations and sales volumes.

Energy and chemical revenues remained essentially flat at $65.4 million in the nine months ended September 30, 2016 compared to $65.5 million in the same period of 2015.

Pulp production decreased marginally to 1,078,057 ADMTs in the nine months ended September 30, 2016 from 1,090,963 ADMTs in the same period of 2015. In the nine months ended September 30, 2016, we had annual maintenance downtime of a total of 31 days (approximately 39,800 ADMTs), 25 days of which were scheduled and 6 days of which were unscheduled to effect additional work at our Celgar mill. In the comparative period of 2015, we had scheduled annual maintenance downtime of 36 days (approximately 50,900 ADMTs).

We estimate that such maintenance downtime in the nine months ended September 30, 2016 adversely impacted our Operating EBITDA by approximately $27.3 million, comprised of approximately $20.3 million in direct out-of-pocket expenses and the balance in reduced production. Many of our competitors that report their financial results using IFRS capitalize their direct costs of maintenance downtime.

Pulp sales volumes decreased marginally to 1,083,570 ADMTs in the nine months ended September 30, 2016 compared to 1,111,257 ADMTs in the same period of 2015.

In the nine months ended September 30, 2016, list prices for NBSK pulp declined from the same period of 2015, largely as a result of the strong dollar and the impact of weakening hardwood pulp prices on NBSK pricing. Average list prices for NBSK pulp in Europe were approximately $800 per ADMT in the nine months ended September 30, 2016, compared to approximately $862 per ADMT in the same period of 2015. Average list prices for NBSK pulp in China and North America were approximately $601 per ADMT and $974 per ADMT, respectively, in the nine months ended September 30, 2016, compared to approximately $657 per ADMT and $981 per ADMT, respectively, in the same period of 2015.

Average pulp sales realizations decreased by approximately 10% to $588 per ADMT in the nine months ended September 30, 2016 from approximately $650 per ADMT in the same period last year primarily due to lower list prices.

In the nine months ended September 30, 2016, the dollar weakened by approximately 3% against the euro, compared to December 31, 2015, which reduced our dollar-denominated cash and receivables held by our German mills and contributed to the negative impact due to foreign exchange of approximately $4.7 million when compared to the same period of the prior year.

Costs and expenses in the nine months ended September 30, 2016 decreased by approximately 6% to $635.2 million from $673.9 million in the same period of 2015, primarily due to lower fiber prices, lower sales volumes and the reversal of a $7.2 million wastewater fee accrual at our Rosenthal mill.

In the nine months ended September 30, 2016, operating depreciation and amortization was $52.8 million, compared to $50.6 million in the same period of 2015.

Selling, general and administrative expenses decreased to $32.1 million in the nine months ended September 30, 2016 from $35.5 million in the same period of 2015 due to lower costs associated with our completed NAFTA claim.

Transportation costs decreased by approximately 11% to $50.8 million in the nine months ended September 30, 2016 from $57.4 million in the same period of 2015 primarily due to lower pulp shipments to China.

On average, in the nine months ended September 30, 2016, overall fiber prices decreased by approximately 7% from the same period of 2015, primarily as a result of a balanced wood market in both Germany and the Celgar mill’s fiber basket. In the nine months ended September 30, 2016, in euro terms, average fiber prices in Germany were approximately 9% lower than the comparative period of 2015. In the nine months ended September 30, 2016, in Canadian dollar terms, average fiber prices for our Celgar mill were marginally lower than the comparative period of 2015.

In the nine months ended September 30, 2016, our operating income decreased by approximately 39% to $74.7 million from $121.5 million in the same period of 2015, primarily due to lower pulp sales realizations, partially offset by lower fiber prices and the reversal of a wastewater fee accrual at our Rosenthal mill.

Interest expense in the nine months ended September 30, 2016 decreased to $38.7 million from $40.6 million in the same period of 2015, primarily as a result of lower indebtedness.

As a result of a weakening of the dollar versus the euro and Canadian dollar in the nine months ended September 30, 2016, we recorded a non-cash gain on the foreign exchange translation of certain intercompany debt between Mercer Inc. and its wholly owned subsidiaries, which increased our net income by $0.3 million.

In the nine months ended September 30, 2016, we had other expenses of $0.6 million which included a loss of $0.5 million due to the write-off of certain deferred financing costs associated with our repurchase and cancellation of $23.0 million of our 2019 Senior Notes.

During the nine months ended September 30, 2016, income tax expense decreased to $19.2 million from $21.8 million in the same period of 2015 due to lower taxable income for our German subsidiaries.

For the nine months ended September 30, 2016, we reported net income of $16.5 million, or $0.25 per basic and diluted share compared to net income of $53.8 million, or $0.84 per basic and $0.83 per diluted share, in the same period of 2015.

In the nine months ended September 30, 2016, Operating EBITDA decreased by approximately 26% to $127.9 million from $172.5 million in the same period of 2015, primarily as a result of lower pulp sales realizations, partially offset by lower fiber prices and the reversal of a wastewater fee accrual.

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. We use Operating EBITDA as a benchmark measurement of our own operating results and as benchmarks relative to our competitors. We consider it to be a meaningful supplement to operating income as a performance measure primarily because depreciation expense and non-recurring capital asset impairment charges are not actual cash costs, and depreciation expense varies widely from company to company in a manner that we consider largely independent of the underlying cost efficiency of our 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, or as an alternative to net cash from operating activities as a measure of liquidity. Operating EBITDA is an internal measure and therefore may not be comparable to other companies. The following table sets forth a reconciliation of net income to Operating EBITDA:
