~ Significant progress on strategic transformation ~

~ Launching plan to eliminate $14 million to $16 million of corporate costs ~

YORK, Pennsylvania – November 6, 2018 – Glatfelter (NYSE: GLT) a leading global supplier of engineered materials, today reported its results for the third quarter of 2018.  As part of the Company’s strategic transformation, Glatfelter completed the sale of its Specialty Papers business unit on October 31, 2018. Accordingly, Specialty Papers’ results are classified as discontinued operations for all periods presented in this release including the recognition of a $97.5 million after-tax impairment charge in connection with the sale of the business unit.  The Company’s third-quarter 2018 and 2017 results are summarized in the following table:

On an adjusted basis, earnings from continuing operations for the third quarter of 2018 were a loss of $0.2 million, or $0.00 per share compared with adjusted earnings of $7.6 million, or $0.17 per diluted share, for the same period a year ago.  Corporate shared services costs totaling $6.9 million and $7.2 million for the third quarter of 2018 and 2017, respectively, previously included in Specialty Papers’ results are required to be included in income from continuing operations.  Adjusted earnings is a non-GAAP financial measure for which a reconciliation to the nearest GAAP-based measure is provided within this release.  

Consolidated net sales totaled $209.9 million and $210.1 million for the three months ended September 30, 2018 and 2017, respectively.  On a constant currency basis, Composite Fibers’ net sales decreased by 0.8% and Advanced Airlaid Materials’ net sales increased by 4.8%.

“We made significant progress on our previously announced strategy to transform Glatfelter into a leading, global engineered materials company,” said Dante C. Parrini, Chairman and Chief Executive Officer.  “We successfully completed two major transactions, both of which closed in October.  The sale of the Specialty Papers business and the acquisition of a nonwovens business in Steinfurt, Germany, support our strategic focus and further solidify our platform for long-term growth.  In addition, we are well positioned for growth to accelerate in our airlaid business driven by our new Fort Smith, Arkansas, facility and the Steinfurt acquisition.”

Mr. Parrini continued, “While we made progress on our transformation, we continue to face competitive market conditions and the impact of the rapid rise in raw material prices in our Composite Fibers business.  We have maintained our focus on reducing costs and improving efficiency to address these challenges and we recently announced price increases for this business.  We are also launching a plan to right-size our corporate cost structure now that the sale of the Specialty Papers business is complete and we expect to eliminate $14 million to $16 million of expenses by the end of 2019.  The growth opportunities we see in front of us and these actions continue to give me confidence in the longer-term potential of our engineered materials businesses and the value they will deliver to our shareholders.”

The following table sets forth a reconciliation of results on a GAAP basis to an adjusted earnings basis, a non-GAAP measure:

Third Quarter Business Unit Results

Composite Fibers

Composite Fibers’ net sales decreased $3.2 million, or 2.2%, primarily due to a 5.8% decline in shipping volumes.  Higher average selling prices totaling $2.2 million offset a $2.0 million impact of unfavorable currency translation.

Composite Fibers’ third quarter of 2018 operating income totaled $11.9 million, a decrease of $4.5 million compared to the year-ago period.  Operating results were adversely impacted by $4.7 million of higher input costs, primarily due to significantly higher woodpulp prices.  Currency translation unfavorably impacted results by $1.8 million.

Advanced Airlaid Materials

Advanced Airlaid Materials’ net sales increased $2.9 million primarily due to $2.0 million from higher selling prices and a 1.0% increase in shipping volumes.

Operating income for the third quarter of 2018 decreased $2.7 million compared to the year-ago period primarily due to higher raw material prices of $1.6 million, a $1.2 million increase in depreciation expense related to the investment in the Fort Smith facility and the impact of higher fixed costs from the new facility with limited shipping volume growth.  Currency translation unfavorably impacted operating income by $0.8 million.

Other Financial Information

In the third quarter of 2018, the Company recorded a tax provision of $3.5 million on pre-tax income from continuing operations of $2.8 million.  On adjusted pre-tax income of $2.0 million, income tax expense was $2.2 million including a $0.9 million impact to deferred taxes from a state tax law change.

Reconciliation of GAAP Financial Information to Non-GAAP Financial Information

This press release includes a measure of earnings before the effects of certain specifically identified items, which is referred to as adjusted earnings, a non-GAAP measure.  The Company uses non-GAAP adjusted earnings to supplement the understanding of its consolidated financial statements presented in accordance with GAAP.  Non-GAAP adjusted earnings is meant to present the financial performance of the Company’s core operations, which consist of the production and sale of composite fibers papers and airlaid non-woven materials.  Management and the Company’s Board of Directors use non-GAAP adjusted earnings to evaluate the performance of the Company’s fundamental business in relation to prior periods.  For purposes of determining adjusted earnings, the following items are excluded:

Unlike net income determined in accordance with GAAP, non-GAAP adjusted earnings does not reflect all charges and gains recorded by the Company for the applicable period and, therefore, does not present a complete picture of the Company’s results of operations for the respective period.  However, non-GAAP adjusted earnings provide a measure of how the Company’s core operations are performing, which management believes is useful to investors because it allows comparison of such operations from period to period.  Non-GAAP adjusted earnings should not be considered in isolation from, or as a substitute for, measures of financial performance prepared in accordance with GAAP.
