Exhibit 99.1

GLATFELTER REPORTS THIRD QUARTER 2016 EARNINGS

YORK, Pennsylvania – November 1, 2016 – Glatfelter (NYSE: GLT) today reported third quarter of 2016 net income of $19.6 million, or $0.44 per diluted share compared with $13.5 million, or $0.31 per diluted share in the third quarter of 2015.  Adjusted earnings for the third quarter of 2016 were $24.0 million, or $0.54 per diluted share compared with $20.8 million, or $0.47 per diluted share, for the same period a year ago.  Adjusted earnings is a non-GAAP measure for which a reconciliation is provided within this release.

Consolidated net sales totaled $405.3 million and $420.0 million in the third quarters of 2016 and 2015, respectively.  Lower selling prices unfavorably impacted the year-over-year comparison by $6.3 million and shipping volumes declined 2.1%.

“Our third quarter results reflect the continuation of challenging conditions in several of our markets,” said Dante C. Parrini, Chairman and Chief Executive Officer.  “While Specialty Papers continued to improve its operating performance driving a 7% increase in operating profit, a soft demand environment in the broader uncoated freesheet market impacted shipping volume and limited the realization of price increases announced earlier this year.  In Composite Fibers, shipping volumes fell short of our expectations as demand for wall cover products was softer than expected.  The weakness in these businesses outweighed the steady performance of our Advanced Airlaid Materials business.  Demand in our airlaid markets remains robust and our wipes volume was up significantly on both a year-over-year and sequential-quarter basis.”

Mr. Parrini continued, “Given the weak global economic environment, we remain focused on aligning our cost structure to most efficiently meet our customers’ needs, deploying new products, optimizing asset utilization and delivering on our operational excellence initiatives.  We will continue to balance these initiatives with targeted investments to grow our business, such as expanding our Advanced Airlaid Materials business by building out our new Fort Smith, Arkansas facility, which we expect to be on-line in early 2018.”

Third Quarter Business Unit Results

Composite Fibers

Composite Fibers’ net sales decreased $2.3 million, or 1.7%, primarily due to $1.6 million from lower selling prices.  Shipping volumes increased slightly in the comparison.  

Composite Fibers’ third quarter of 2016 operating income totaled $14.0 million, a decrease of $0.1 million compared to the year-ago period.  Slightly higher shipping volumes, more efficient operations, net of market related downtime, and lower raw material and energy prices improved operating results by $3.0 million which more than offset the impact of lower selling prices.  Foreign currency translation adversely impacted results by $1.5 million reflecting the less favorable impact from hedging activities in 2016 compared to 2015.

Advanced Airlaid Materials

Advanced Airlaid Materials’ net sales decreased $1.3 million in the year-over-year comparison primarily due to $2.2 million of lower selling prices.  Shipping volumes increased 1.8%, or 5.6% on a square meter basis, primarily due to higher shipments of wipes products.

Operating income for the third quarter of 2016, totaled $6.4 million, 5.7% lower than the comparable period a year ago.  Operating income benefited by $2.3 million from lower raw material and energy prices partially offset by lower selling prices related to the impact of cost pass through arrangements. In addition, foreign currency translation unfavorably impacted the comparison by $0.7 million reflecting the less favorable impact from hedging activities in 2016 compared to 2015.

Specialty Papers

Specialty Papers’ net sales decreased $11.0 million, or 5.0%, due to a 3.1% decline in shipping volumes and a $2.5 million impact from lower selling prices.

Specialty Papers’ operating income totaled $18.7 million in the third quarter of 2016, or an increase of $1.2 million compared with the same period a year ago.  Lower raw material and energy costs essentially offset the adverse impact of lower selling prices while improved productivity more than offset the impact of higher incentive compensation in the third quarter of 2016.

Other Financial Information

Pension expense totaled $1.4 million and $2.2 million in the third quarter of 2016 and 2015, respectively.  For 2016, full year pension expense is expected to be $5.5 million.  Because the Company’s qualified plan remains overfunded, a cash contribution is not expected for the foreseeable future.

The Company’s effective tax rate was 6.7% and 14.5% for the third quarters of 2016 and 2015, respectively. On adjusted earnings, the  effective tax rate was 13.0% in the third quarter of 2016 compared to 23.8% in the same quarter a year ago.  The third quarter 2016 tax rate benefited by $2.4 million primarily from investment tax credits, release of reserves due to completion of tax audits and changes in statutory tax rates.

Outlook

Composite Fibers’ shipping volumes in the fourth quarter of 2016 are expected be approximately 5% lower than the third quarter driven by lower sales of metalized products.  Selling prices and raw material and energy prices are expected to be in-line with the third

quarter.  The Company anticipates the impact of machine downtime to reduce inventory levels will be largely offset by cost reduction initiatives.

Advanced Airlaid Materials’ shipping volumes are expected to decline slightly compared with the third quarter.  Customer selling prices and raw material and energy prices are expected to be in-line with the third quarter.

For Specialty Papers, shipping volumes in the fourth quarter are expected to be in-line with the third quarter.  Lower selling prices and mix changes are expected to reduce operating profit by approximately $5 million. The impact of machine downtime to reduce inventory levels is expected to be offset by lower maintenance costs. Raw material and energy prices are expected to increase moderately.

Reconciliation of GAAP Financial Information to Non-GAAP Financial Information

This press release includes a discussion 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 consists of the production and sale of specialty papers, 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.  The performance of the Company’s operations is evaluated based upon numerous items such as tons sold, average selling prices, gross margins and overhead, among others.  Items of an unusual or non-routine nature, such as gains on the sale of timberlands, costs related to Specialty Papers’ environmental compliance and Advanced Airlaid Materials capacity expansion projects, among others, are excluded from the Company’s calculation of non-GAAP adjusted earnings because management believes each of these items is unique and not part of the Company’s core business, and will only impact the Company’s financial results for a limited period of time.  Gains from timberland sales are distinct from revenues generated from product sales.  Unlike items such as cost of raw materials and overhead costs, the environmental compliance and capacity expansion projects are unique items that do not represent direct ongoing costs incurred in the manufacture and sale of the Company’s products.

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 provides 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.

The amounts set forth above as of December 31, 2015, have been restated to retroactively adopt Accounting Standards Number 2015-03, Interest - Imputation of Interest (Subtopic 835-30) Simplifying the Presentation of Debt Issuance Costs.
