For Immediate Release

Wednesday, July 21, 2010

Charlotte, N.C. — Polymer Group, Inc. (PGI) (OTC Bulletin Board: POLGA/POLGB) today announced that, as part of its ongoing due diligence process related to the previously announced evaluation of strategic alternatives, it has determined that a tax liability associated with uncertain tax positions should have been recorded in reported results of operations for each quarterly and annual reporting period from the first quarter of 2007 to the first quarter of 2010 in accordance with the provisions set forth in Financial Accounting Standards Board Accounting Standards Codification (ASC) 740 — Income Taxes.

The Internal Revenue Code of 1986, as amended (IRC), contains highly specialized provisions relating to circumstances under which a company may be designated as a “personal holding company” (PHC).  The PHC rules are commonly understood by tax professionals to be focused on penalizing individuals who use holding companies to hold personal investments when the individual tax rates exceed corporate tax rates, and are therefore not typically applicable to public companies, such as PGI, whose primary source of income is from operating activities.  The Company has historically relied upon multiple third party tax professionals to assist in the preparation of its income tax filings and to advise on the Company’s tax structures.  In response to inquiries from additional third parties involved in exploring strategic alternatives with the company, an evaluation of the relevant IRC sections pertaining to the company’s intercompany loans and intellectual property agreements, and requested ownership information received from its majority stockholders, the company has determined it may have met certain requirements outlined in Section 542 of the IRC and earned income that may be classified as undistributed PHC income as defined in Section 545 of the IRC.

PGI’s chief executive officer, Veronica (Ronee) M. Hagen, stated, “This issue is limited to potential tax liability for past periods and does not adversely reflect on the company’s strong operations or the fundamentals of our business.  We are pleased with the strong underlying trends that are continuing in our business, and the leadership we are demonstrating in our markets.”

The company has evaluated various tax settlement positions associated with the issue and determined that an aggregate tax liability of approximately $24 million to $25 million should be recognized for fiscal years 2007, 2008, and 2009. The predominant amount of the liability will be reflected in fiscal 2007 as an adjustment to retained earnings and noncurrent liabilities on the balance sheet, with subsequent income statement adjustments to be made to reflect interest on the prior period amounts and nominal PHC liability after that time.  Despite the contingent liability being recognized in the financial statements, the company believes the PHC rules were not intended to apply to its situation and intends to seek a ruling from the Internal Revenue Service (the “IRS”).  However, the company cannot be certain of the outcome of discussions with the IRS, and the amount of any taxes, interest or penalties that may be required to be paid, until a determination or ruling is received.  Regardless of the outcome of discussions with the IRS regarding past periods, the company expects to take steps to fully mitigate any on-going exposure for future periods.

“We are working diligently and proactively to resolve this highly complex tax matter.  We do not believe this issue will affect our ability to execute on our growth plans or materially impact the company’s overall financial condition,” said Dennis E. Norman, executive vice president and chief financial officer.

The company intends to restate its financial statements for fiscal years 2007, 2008 and 2009 by filing with the Securities and Exchange Commission by mid-August an amended Annual Report on Form 10-K for fiscal year 2009 and an amended Quarterly Report on Form 10-Q for the quarter ended April 3, 2010. The company anticipates reporting its results for the second quarter of 2010 at that time consistent with its usual reporting calendar.

The PHC issue was identified as part of the company’s process to review strategic alternatives, which has had an impact on the timing of that review. That process, however, is ongoing and the company has not set a definitive timetable for completion of its evaluation.  There can be no assurances that the process will result in any transaction being announced or being completed.
