NOTE: The financial statements set forth in this Exhibit 99.1 have been prepared in accordance with accounting principles generally accepted in Germany.

Annual Financial Statements for the Financial Year

From January 1 through December 31, 2012

Independent Auditor’s Report To Dresden Papier GmbH, Dresden/Germany:

We have audited the accompanying financial statements of Dresden Papier GmbH, which comprise the balance sheet as of December 31, 2012, and the related statements of income and cash flows for the year then ended, and the related notes to the financial statements.

Management’s Responsibility for the Financial Statements Management is responsible for the preparation and fair presentation of the financial statements in accordance with the requirements of German Commercial Law (HGB); this includes the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of financial statements that are free from material misstatement, whether due to fraud or error.

Auditor’s Responsibility Our responsibility is to express an opinion on these financial statements based on our audit. We conducted our audit in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the financial statements. The procedures selected depend on our judgment, including the assessment of the risks of material misstatement of the financial statements, whether due to fraud or error. In making those risk assessments, we consider internal control relevant to the Company’s preparation and fair presentation of the financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control. Accordingly, we express no such opinion. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall presentation of the financial statements.

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Opinion In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Dresden Papier GmbH as of December 31, 2012, and the results of its operations and its cash flows for the year then ended in accordance with the requirements of German Commercial Law (HGB).

Other Matter The accompanying balance sheet of Dresden Papier GmbH, as of December 31, 2011, and the related statements of income and cash flows for the year then ended, and the related notes to these financial statements were not audited, reviewed, or compiled by us and, accordingly, we do not express an opinion or any other form of assurance on them.

Dresden Papier GmbH, Dresden Notes to the Financial Statements for the Financial Year from January 1 through December 31, 2012

I. General Information The annual financial statements for the period from January 1 through December 31, 2012 have been prepared in accordance with the provisions applicable to corporations of the German Commercial Code [Handelsgesetzbuch — HGB] and the regulations set out in the Law relating to Limited Liability Companies [Gesetz betreffend die Gesellschaften mit beschränkter Haftung — GmbHG].

The Company is a large corporation within the meaning of Section 267 (3) and (4) HGB.

The income statement has been classified according to the type-of-expenditure format pursuant to Section 275 (2) HGB.

II. Valuation Methods In detail, the following accounting and valuation methods are applied:

Assets and liabilities are in general valued separately.

Intangible assets acquired for a monetary consideration are measured at acquisition cost less scheduled amortization and impairment. Acquisition cost also comprises the ancillary costs of acquisition that are individually attributable and subsequent acquisition costs. Purchase price reductions are deducted from acquisition cost.

Fixed assets are stated at depreciated acquisition or production cost. Depreciation is charged in accordance with the expected useful lives. Low-value asset items with individual acquisition costs of more than €€ 150 and up to €€ 1,000 are combined in collective items (without taking account of the actual wear and tear and without considering whether the assets remain with the company or not) and depreciated over a period of five years.

The inventories of raw materials and supplies are capitalized at average acquisition prices. Finished goods are measured at production costs, which comprise directly attributable material costs, manufacturing wages and special direct costs as well as manufacturing and material overheads and depreciation. Merchandise is accounted for at average acquisition costs. The lower-of-cost-or-market principle has been considered in the valuation of inventories.

Emission allowances acquired for a monetary consideration are classified as merchandise. They have been stated at acquisition cost and, if required, written down to their fair value.

Receivables and other assets are generally recognized at their nominal values. All items subject to risk have been accounted for by setting up adequate individual valuation allowances; the general credit risk of default has been covered by a 1% allowance on all uninsured receivables not themselves subject to individual valuation allowances.

Payments made prior to the balance sheet date to the extent they represent expenditure for a certain period after that date are recorded as prepaid expenses and deferred charges.

The subscribed capital is reported at nominal value. Provisions cover all contingent liabilities, anticipated losses from pending transactions as well as tax provisions. They are recognized at the amounts deemed necessary according to reasonable commercial judgment. Provisions with a residual term of more than one year are principally discounted using the market interest rate of the previous seven financial years corresponding to the residual term of the provisions.

The provision for anniversary obligations is measured using a discount rate of 5.05% p.a. and on the basis of the “2005 G Life Expectancy Tables” by Prof. Dr. Klaus Heubeck using actuarial principles.

Liabilities are recognized at the amounts repayable.

Transactions denominated in foreign currencies (always of a short-term nature) are principally recognized using the historical rate applicable at the time at which the transaction was initially recognized and are valued at the average exchange rate as of the balance sheet date.

Deferred taxes are recognized in relation to the differences between the carrying amounts shown in the commercial balance sheet and the tax balance sheet if such differences will probably be reversed in subsequent financial years. Deferred tax assets and deferred tax liabilities are shown as netted figures. If the netting results in a net deferred tax asset as of the balance sheet date, the capitalization option for deferred tax assets set out in Section 274 (1) Clause 2 HGB is not utilized. The deferred taxes are calculated using an effective tax rate of 30.7% (15.825% for the corporate income tax including solidarity surcharge and 14.875% for the trade tax). The tax rate for trade tax is based on the average trade tax assessment multiplier of 425%.

III. Comments on the Balance Sheet

Fixed assets taken over as of August 1, 2006 are depreciated using the straight-line method. Additions made during the period from August 1, 2006 to December 31, 2008 are depreciated on a straight-line basis. Moveable technical fixed assets acquired after January 1, 2009 up to and including December 31, 2009 were depreciated using the declining-balance method pursuant to Section 7 (2) EStG [German Income Tax Act] until December 31, 2010. Since January 1, 2010 moveable technical fixed assets have been depreciated equally using the straight-line method.

The composition and development of the individual items of fixed assets are shown in the fixed-asset movement schedule contained in the Annex to the Notes.

1. Fixed assets

As was the case in the prior year, all trade receivables and other assets have a residual term of less than one year, except for loan claims on shareholders as set out below.

Receivables from affiliated companies solely refer to shareholders and are the result of a loan contract with a term until June 30, 2017.

Other assets mainly result from tax refund claims regarding value-added tax in the amount of T€€ 662 (thereof T€€ 70 have legally not occurred yet) and mineral oil and electricity tax in the amount of T€€ 849.

The credit balances for bonus reserves held with the factoring company which are disclosed under cash and cash equivalents (T€€ 5,100) are restricted and are released for the purpose of paying bonuses and discounts in January 2013.

The determination of deferred taxes from temporary differences between the commercial balance sheet and the tax balance sheet resulted a net deferred tax asset in the amount of T€€ 41 as of the balance sheet date. The Company does not make use of the capitalization option set out in Section 274 (1) Clause 2 HGB, which means that the net deferred tax asset is not recognized in the balance sheet. The differences between the commercial and the tax balance sheet, which give rise to deferred tax assets, result mainly from:

The special account contains investment grants received pursuant to the Law on Investment Grants [InvZulG], as well as investment subsidies from the joint community task “improvement of the regional economic structure” in Saxony. These grants and subsidies are released in accordance with the depreciation process concerning the respective subsidized assets.

Other provisions with individual amounts exceeding T€€ 300 refer primarily to bonuses and commissions as well as provisions for outstanding suppliers’ invoices and personnel-related provisions.

The provision for semi-retirement obligations (T€€ 56) is offset against the respective plan assets (T€€ 51), which serve the exclusive purpose of settling liabilities relating to old-age pension obligations (outstanding settlement amount) and are protected against access by any third parties. The plan assets, which are designated for a specific purpose and are pledged, are measured in general at their fair value. The plan assets relate to fixed-income securities the acquisition cost of which amount to T€€ 46.

2. Receivables and other assets

• Differences in the valuation of provisions

• Findings from the government tax audit, which have not been retraced for commercial law purposes (refers to software and

receivables from affiliated companies).

3. Special account for investment grants and subsidies

4. Other provisions

The liabilities have the following residual terms:

Bank loans and overdrafts to the amount of T€€ 22,596 are collateralized by registered land charges on the Company’s premises (original amount: T€€ 25,000), the assignment of the paper machine including all components as collateral, the assignment of the inventories as collateral (in particular wallpaper base and non-woven) and letters of subordination by the shareholders with respect to extended loans (T€€ 24,000).

Other liabilities 1,646 — — 1,646 (December 31, 2011 unaudited 1,235 — — 1,235 )

35,209 17,500 — 52,709

In addition to that, financial covenants which are determined from the quarterly and annual financial statements of Dresden Papier GmbH have to be complied with.

The Company is exposed to interest rate risks within the scope of its operations. The interest rate risk of bank loans subject to variable interest rates is minimized by means of interest rate swaps.

In 2012, an interest rate swap was entered into. It was combined with the underlying bank loan to form a valuation unit. As the swap with a nominal value of €€ 21.4 million corresponds to the underlying loan (value as of December 31, 2012: €€ 22.5 million) with respect to all major terms and conditions, it can be assumed that the cash flows from the interest rate hedge will fully set off each other during the remaining term of the derivatives and that a hedging of fixed interest rates is therefore achieved. For showing the effective part of the valuation units which are created in the accounts, the so-called net hedge presentation method (compensatory valuation) is used. The present values of the individual interest rate swaps were taken from the banks’ valuation statements. Each valuation reflects the bank’s assessment of the value of a specific financial instrument under the given market conditions. The market values of the swaps were determined using the money market and swap rates and discounting the future cash flows. The interest rate swap has a term until June 30, 2017.

In connection with the raising of a loan, borrowing costs of €€ 247,500 had to be paid. These were capitalized in prepaid expenses and deferred charges and spread over the non-cancellable term of the loan contract using the effective interest method.

Payables to affiliated companies refer to loans from the shareholder (T€€ 24,000). With regard to loan repayment, regulations have been agreed between the lender and the Company, ensuring the Company’s ability to pay at all times and excluding any insolvency due to a repayment obligation. Therefore, the Company’s ability to continue its business will be assured.

With respect to trade payables, there is the usual retention of title from the delivery of raw materials and supplies as well as merchandise.

IV. Comments on the Income Statement

The sales (net) from the delivery of wallpaper and non-woven wallpaper can be broken down as follows:

The following overview reflects a breakdown of sales according to geographically defined markets:

Expenses not relating to the period under review in the amount of T€€ 95 are reported within other operating expenses. Factoring charges of T€€ 364 associated with the use of factoring are also included. A prepayment penalty of T€€ 1,992 resulted from the repayment of a loan. Other operating expenses include unrealized exchange losses of T€€ 1 (prior year unaudited: T€€ 2).

Expenses relating to auditors’ fees amount to T€€ 31 for auditing services associated with the annual financial statements and T€€ 26 for other affirmation services.

These financial statements have been prepared in accordance with accounting principles generally accepted in Germany (“HGB”) which, in many respects, conforms to accounting principles generally accepted in the United States of America (“U.S. GAAP”). The significant difference in those principles, as they apply to the Company’s net earnings and shareholders’ equity, are described below.

Net earnings for the year based on U.S. GAAP €€ 15,756,898.01

(a) Under HGB, the Company designated an interest rate swap as a cash flow hedge for accounting purposes. As permitted by HGB, since the interest rate swap effectively converted a variable rate loan to a fixed rate with identical terms, the change in fair value related to the interest rate swap was not reflected in the Company’s balance sheet or profit and loss statement. For U.S. GAAP purposes, the Company did not qualify for hedge accounting. Accordingly, the change in fair value of this interest rate swap is reported as a charge to earnings.

Reconciling Items impacting the Statement of Cash Flow activity

Restricted cash The Company maintains credit balances for bonus reserves with the factoring company (December 31, 2012 T€€ 5,100). Under US GAAP, given the nature of the restricted cash, changes in the restricted cash balances would be reported as an investing activity in the Statement of Cash Flows and restricted cash would not be included in cash and cash equivalents as of the balance sheet dates.

On March 13, 2013, Fortress Security Papers AG entered into a Share Purchase Agreement pursuant to which Dresden Papier was sold to Glatfelter Gernsbach GmbH, a wholly owned subsidiary of P. H. Glatfelter Company. The sale was completed on April 30, 2013.

The following sets forth the preliminary purchase price allocation:

The Acquisition agreement provides for a purchase price of €€ 160 million (or $211.0 million based on the December 31, 2012 foreign exchange rate), subject to an adjustment based on the closing date working capital of Dresden, which has not yet been agreed to. The preliminary purchase price allocation set forth above is based on the preliminary working capital adjustment of €€ 10.7 million (or $14.0) million based on the December 31, 2012 foreign exchange rate). We are in the process of completing valuations necessary to account for the Acquisition in accordance with the acquisition method of accounting set forth in FASB ASC 805, Business Combinations, including independent appraisals. In calculating the pro forma adjustments, the purchase price has been allocated on a preliminary basis. Therefore, the purchase price allocation is subject to change, and such changes could be material. The preliminary allocation of the purchase price set forth in the pro forma balance sheet assumes the excess of book value will be allocated as set forth above, an assumption we believe is reasonable based on information presently available to us. Our allocation shown above includes an allocation to indentified intangible assets consisting of tradename, technology and customer relationships. For purposes of presenting depreciation and amortization expense in the pro forma income statement, fixed assets and intangible assets are assumed to have an average remaining useful life of 19 years and 17 years, respectively. Expense is recognized on a straight-line basis.

(2) Reflects the use of $96.2 million of Glatfelter’s cash to partially fund the Acquisition. (3) The pro forma adjustments reflect the Acquisition and allocation of the purchase price adjustments as follows:
