NEW YORK, May 07, 2026 (GLOBE NEWSWIRE) -- Mercer International Inc. (NASDAQ:MERC) today reported first quarter 2026 Operating EBITDA of $7.8 million, a decrease from $47.1 million in the same quarter of 2025 and an increase from negative $20.1 million in the fourth quarter of 2025.

In the first quarter of 2026, net loss was $52.0 million ($0.78 per share) compared to $22.3 million ($0.33 per share) in the same quarter of 2025 and $308.7 million ($4.61 per share) in the fourth quarter of 2025.

Mr. Juan Carlos Bueno, Chief Executive Officer, stated: "Our pulp sales realizations showed resilience this quarter as softwood pulp markets held steady, while hardwood pulp performance trended upward on favorable demand-supply dynamics. However, elevated fiber costs across our supply chain and a slower-than-anticipated recovery in prices continued to weigh on our results. As a result, we recognized a non-cash impairment of $22 million against pulp and fiber inventory. We are starting to see supply responses to prevailing market conditions and currently expect a more balanced market in the later half of 2026.

The current conflicts in the Middle East and their impacts on energy supply are creating significant inflationary pressures and further economic uncertainty. We believe these conditions may negatively impact demand for our products and increase certain operating costs, such as chemicals and freight. Conversely, high oil prices are raising interest in bio-substitution, as expensive oil-based synthetics drive increased demand for lower-cost, wood-pulp-derived alternatives. While the potential impacts and duration of these conditions are currently unknown, we continue to monitor and assess these events.

We continue to pursue our "One Goal One Hundred" program and remain confident that we will achieve our targeted $100 million in cost savings and operational efficiencies by year end. With $11 million in profitability actions realized this quarter, our cumulative total has reached approximately $41 million since its launch in April 2025. The program is part of our broader initiatives to improve our balance sheet and preserve cash, including efforts to reduce capital expenditures and optimize working capital.

In the first quarter of 2026, European softwood pulp prices increased compared to the fourth quarter of 2025 due to supply constraints, although these gains were offset by higher discounts. In China, softwood pulp pricing remained under pressure from an oversupplied paper sector and ongoing economic uncertainties, while excess inventory tempered the North American market. Conversely, hardwood pulp prices increased globally due to stronger demand and tightening inventory levels. Looking ahead to the second quarter, we expect softwood pulp prices to increase modestly across all markets, with hardwood pricing remaining relatively steady.

Our lumber sales realizations in both the U.S. and Europe were relatively stable in the first quarter of 2026. For the second quarter, we currently expect lumber prices to remain stable in Europe and modestly increase in the U.S. due to low supply.

Per unit fiber costs for our pulp and solid wood segments increased in the first quarter of 2026 compared to the fourth quarter of 2025 driven by supply constraints and strong demand. We currently expect per unit fiber costs to stabilize in the second quarter of 2026 as improved availability is offset by strong demand.

In the first quarter of 2026, we had relatively stable production but fiber constraints in Europe required us to strategically reduce production at our German mills by approximately 20,000 tonnes. There was no annual planned maintenance downtime in the first quarter of 2026 and none is currently scheduled for the second quarter.

Overall, our solid wood segment remains pressured by high U.S. interest rates and European economic headwinds. As conditions improve, we expect a strong recovery, with pent-up demand and supply constraints eventually driving higher pricing. Current geopolitical conflicts may delay any economic recovery. With the installation of new scanning technology currently underway at Torgau that is expected to be operational in the second quarter, we are well positioned to increase our production of on-grade dimensional lumber. This allows us to scale our exports to the U.S. market, enabling us to shift more of our existing production into higher-value dimensional products. Within this segment, our mass timber order book and commitments grew to approximately $171 million this quarter. This portfolio is increasingly weighted toward large-scale projects related to data center infrastructure, representing approximately 60% of our existing project pipeline. We expect these contracts to begin contributing to our results as they commence in late 2026 and into 2027.

As a result of ongoing economic uncertainty and softness in the markets for our products, we did not meet the requisite leverage ratio required under our German revolving credit facility at the end of the first quarter. As announced, to address this, we secured a waiver of the applicable covenant from the lenders under the facility. Based on management's current forecasts and assumptions, including with respect to pricing and demand for our products, we currently expect to achieve compliance with the leverage ratio by the fourth quarter of 2026. Accordingly, amounts outstanding under our German revolving credit facility remain classified as "non-current liabilities" at the end of the first quarter.

The waiver gives us additional flexibility to pursue and implement measures and solutions with the goal of enhancing our liquidity and financial condition in the current economic environment, including to address maturing indebtedness, and to assist our positioning for an eventual market recovery. To this end, we are also evaluating strategic alternatives and financing options to address our liquidity needs and goals. Our board of directors has appointed a special committee of independent directors to oversee, review and evaluate the development and implementation of potential liquidity management strategies and other transactions to improve our capital structure."

Mr. Bueno concluded: "In the first quarter of 2026, economic headwinds continued and were accompanied by geopolitical volatility. In these difficult conditions, the steps being taken to address liquidity, combined with our ongoing focus on production discipline and the "One Goal One Hundred" program, are intended to position us to capture market upside when conditions improve towards the second half of the year."

Consolidated – Three Months Ended March 31, 2026 Compared to Three Months Ended March 31, 2025

Total revenues for the first quarter of 2026 decreased by approximately 3% to $489.3 million from $507.0 million in the same period of 2025. This decrease was primarily due to lower pulp sales realizations partially offset by modestly higher sales realizations from our other products.

Costs and expenses in the first quarter of 2026 increased by approximately 4% to $522.2 million from $500.2 million in the same period of 2025. This increase was primarily due to the negative foreign exchange impact from a weaker dollar on our euro and Canadian dollar denominated costs and expenses and higher per unit fiber costs partially offset by lower maintenance costs. In the first quarter of 2026, costs and expenses included a non-cash inventory impairment of $22.0 million against pulp and fiber inventory due to low pulp prices and high fiber costs.

In the first quarter of 2026, Operating EBITDA decreased to $7.8 million, which includes the $22.0 million non-cash inventory impairment, from $47.1 million in the same period of 2025. This decrease primarily resulted from lower pulp sales realizations, higher per unit fiber costs, and the negative foreign exchange impact from a weaker dollar partially offset by lower maintenance costs.

Segment Results

Energy and chemical revenues	$	25,813	$	24,116
Segment Operating EBITDA⁽¹⁾	$	6,897	$	49,872

In the first quarter of 2026, Segment Operating EBITDA for the pulp segment decreased to $6.9 million from $49.9 million in the same period of 2025. This decrease primarily resulted from lower pulp sales realizations, higher per unit fiber costs, and the negative foreign exchange impact from a weaker dollar partially offset by lower maintenance costs. In the first quarter of 2026, Segment Operating EBITDA also included a non-cash inventory impairment of $22.0 million.

Pulp segment revenues, comprised of pulp, energy and chemical revenues, in the first quarter of 2026 decreased by approximately 9% to $345.0 million from $381.1 million in the same period of 2025 driven by lower pulp revenues.

Pulp revenues in the first quarter of 2026 decreased by approximately 11% to $319.2 million from $357.0 million in the same period of 2025 primarily as a result of lower sales realizations.

In the first quarter of 2026, the third-party industry quoted average list price for NBSK pulp in Europe modestly increased compared to the same period of 2025 primarily due to supply constraints. In the first quarter of 2026, the third-party industry quoted average list price for NBSK pulp in North America and the third-party industry quoted average net price for NBSK pulp in China decreased compared to the same period of 2025. The decrease was primarily due to weak demand driven by the current economic climate and, in China, an oversupplied paper market. Our average NBSK pulp sales realizations in the first quarter of 2026 decreased by approximately 11% to $696 per ADMT from $783 per ADMT in the same period of 2025 due to lower prices in North America and China.

In the first quarter of 2026, the third-party industry quoted average list price for NBHK pulp in North America and the third-party industry quoted average net price for NBHK pulp in China modestly increased from the same period of 2025 primarily due to global supply constraints. In the first quarter of 2026, average NBHK pulp sales realizations remained flat at $564 per ADMT compared to $570 per ADMT in the same period of 2025.

Pulp sales volumes in the first quarter of 2026 were relatively steady at 470,700 ADMTs compared to 477,879 ADMTs in the same period of 2025.

Energy and chemical revenues in the first quarter of 2026 were relatively flat at $25.8 million compared to $24.1 million in the same period of 2025.

Costs and expenses in the first quarter of 2026 remained stable at $366.9 million compared to $360.9 million in the same period of 2025 as higher per unit fiber costs and the negative foreign exchange impact from a weaker dollar on our euro and Canadian dollar denominated costs and expenses were partially offset by lower maintenance costs. In the first quarter of 2026, costs and expenses included a non-cash inventory impairment charge of $22.0 million against inventory as a result of low pulp prices and high fiber costs.

Total pulp production in the first quarter of 2026 was relatively flat at 465,717 ADMTs compared to 458,909 ADMTs in the same period of 2025. There was no planned maintenance downtime in the first quarter of 2026, compared to 22 days (approximately 29,700 ADMTs) at our Celgar mill in the same period of 2025. This benefit was mostly offset by the impact of reduced production at our German mills due to fiber supply constraints in Europe.

Overall average per unit fiber costs in the first quarter of 2026 increased by approximately 22% compared to the same period of 2025 primarily as a result of reduced supply in Germany and Canada. For the second quarter of 2026, we currently expect per unit fiber costs to stabilize as improved availability is offset by strong demand.

^{(3) Segment Operating EBITDA is a measure of segment profit or loss presented in our financial statements under GAAP. Refer to the segment information note in our consolidated financial statements for more information.}

In the first quarter of 2026, Segment Operating EBITDA for the solid wood segment was negative $5.6 million compared to negative $0.3 million in the same period of 2025. This primarily resulted from higher per unit fiber costs partially offset by modestly higher sales realizations for most of our products.

Solid wood segment revenues in the first quarter of 2026 increased by approximately 7% to $131.7 million from $122.7 million in the same period of 2025 as a result of higher revenue from all product categories except for lumber.

Lumber revenues in the first quarter of 2026 decreased by approximately 8% to $60.1 million from $65.4 million in the same period of 2025 primarily due to lower sales volumes. Average lumber sales realizations in the first quarter of 2026 increased by approximately 7% to $536 per Mfbm from $499 per Mfbm in the same period of 2025 primarily as a result of lower supply and higher fiber costs in the European market. This increase was partially offset by lower average sales realization in the U.S. market due to weak demand. The U.S. market accounted for approximately 46% of our lumber revenues and approximately 42% of our lumber sales volumes in the first quarter of 2026. The balance of our lumber sales was mainly to Europe.

Lumber sales volumes in the first quarter of 2026 decreased by approximately 14% to 112.1 MMfbm from 130.9 MMfbm in the same period of 2025 as a result of lower production.

In the first quarter of 2026, manufactured products revenues increased by approximately 12% to $21.0 million from $18.8 million in the same period of 2025 primarily due to higher sales volumes partially offset by lower sales realizations. Manufactured products sales realizations decreased by approximately 36% to $1,801 per cubic meter in the first quarter of 2026 from $2,832 per cubic meter in the same period of 2025 as construction activity was weighted toward modest-scale projects amid an elevated interest rate environment in the U.S.

Lumber production in the first quarter of 2026 decreased by approximately 9% to 115.9 MMfbm from 128.0 MMfbm in the same period of 2025 due to fiber supply constraints.

Fiber costs were approximately 85% of our lumber cash production costs in the first quarter of 2026. In the first quarter of 2026, per unit fiber costs for lumber production increased by approximately 36% compared to the same period of 2025 due to reduced supply and strong demand. For the second quarter of 2026, we currently expect per unit fiber costs to be flat as the positive impact of improved supply will be offset by strong demand.

Liquidity

As of March 31, 2026, we had cash and cash equivalents of $84.5 million. After taking into account the Waiver and the €70 million reduction in borrowing capacity thereunder, we had approximately $144.5 million available under our revolving credit facilities, bringing aggregate liquidity to about $229.0 million as of March 31, 2026.

COMPUTATION OF OPERATING EBITDA

(Unaudited)

(In thousands)

Operating EBITDA is defined as operating income (loss) plus depreciation and amortization and long-lived 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 long-lived asset impairment charges are not actual cash costs, and depreciation expense varies widely from company to company in a manner that management considers largely independent of the underlying cost efficiency of our operating facilities. In addition, management believes 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, income taxes 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 operating income (loss) as a measure of performance, nor as an alternative to net cash from (used in) operating activities as a measure of liquidity. Operating EBITDA is an internal measure and therefore may not be comparable to other companies.

Operating EBITDA is a non-GAAP financial measure at the consolidated level and is considered different from Operating EBITDA at the segment level, referred to as "Segment Operating EBITDA", which is our single measure of segment profit or loss presented in our financial statements under GAAP. For more information on Segment Operating EBITDA, refer to the segment information note within our consolidated financial statements.
