Forward-looking Statements

This Quarterly Report on Form 10-Q includes “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the Private Securities Litigation Reform Act of 1995. All statements other than statements of historical facts included in this Quarterly Report on Form 10-Q that address activities, events or developments that we expect, believe or anticipate will or may occur in the future are forward-looking statements, including, in particular, the statements about Polypore International’s plans, objectives, strategies and prospects regarding, among other things, the financial condition, results of operations and business of Polypore International and its subsidiaries. We have identified some of these forward-looking statements with words like “believe,” “may,” “will,” “should,” “expect,” “intend,” “plan,” “predict,” “anticipate,” “estimate” or “continue” and other words and terms of similar meaning. These forward-looking statements may be contained under the captions “Management’s Discussion and Analysis of Financial Condition and Results of Operations” or “Controls and Procedures,” the Company’s financial statements or the notes thereto or elsewhere in this Quarterly Report on Form 10-Q.

These forward-looking statements are based on current expectations about future events affecting us and are subject to uncertainties and factors relating to our operations and business environment, all of which are difficult to predict and many of which are beyond our control. Many factors mentioned in our discussion in this Quarterly Report on Form 10-Q, including the risks outlined under the caption entitled “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 29, 2012, will be important in determining future results. Although we believe that the expectations reflected in our forward-looking statements are reasonable, we do not know whether our expectations will prove correct. They can be affected by inaccurate assumptions we might make or by known or unknown risks and uncertainties, including with respect to Polypore International, the following, among other things:

· the highly competitive nature of the markets in which we sell our products;

· the failure to continue to develop innovative products;

· the loss of our customers;

· the vertical integration by our customers of the production of our products into their own manufacturing process;

· increases in prices for raw materials or the loss of key supplier contracts;

· our substantial indebtedness;

· interest rate risk related to our variable rate indebtedness;

· our inability to generate cash;

· restrictions related to the senior secured credit agreement;

· employee slowdowns, strikes or similar actions;

· product liability claims exposure;

· risks in connection with our operations outside the United States, including compliance with applicable anti-corruption laws;

· the incurrence of substantial costs to comply with, or as a result of violations of, or liabilities under environmental laws;

· the failure to protect our intellectual property;

· the loss of senior management;

· the incurrence of additional debt, contingent liabilities and expenses in connection with future acquisitions;

· the failure to effectively integrate newly acquired operations;

· lithium market demand does not materialize as anticipated;

· the absence of expected returns from the intangible assets we have recorded;

· the adverse impact from legal proceedings on our financial condition; and

· natural disasters, epidemics, terrorist acts and other events beyond our control.

Because our actual results, performance or achievements could differ materially from those expressed in, or implied by, the forward-looking statements, we cannot give any assurance that any of the events anticipated by the forward-looking statements will occur or, if any of them do, what impact they will have on Polypore International’s results of operations and financial condition. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this Quarterly Report on Form 10-Q. We do not undertake any obligation to update these forward-looking statements to reflect new information, future events or otherwise, except as may be required under federal securities laws.

1. Description of Business and Basis of Presentation

Description of Business

Polypore International, Inc. (the “Company”) is a leading global high-technology filtration company that develops, manufactures and markets specialized microporous membranes used in separation and filtration processes. The Company has a global presence in the major geographic markets of North America, South America, Europe and Asia.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and all majority-owned subsidiaries after elimination of intercompany accounts and transactions. The unaudited condensed consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles for interim financial information. Accordingly, the unaudited condensed consolidated financial statements and notes do not contain certain information included in the Company’s annual financial statements. In the opinion of management, all normal and recurring adjustments that are necessary for a fair presentation have been made. Operating results for the three months ended March 30, 2013 are not necessarily indicative of the results that may be expected for the fiscal year ending December 28, 2013. The unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements in the Company’s Annual Report on Form 10-K for the fiscal year ended December 29, 2012.

2. Inventories

Inventories are carried at the lower of cost or market using the first-in, first-out method of accounting and consist of:

(in thousands)	March 30, 2013		December 29, 2012
Raw materials	$	41,332	$	44,285
Work-in-process	30,082		28,051
Finished goods	53,265		47,573
	$	124,679	$	119,909

3. Debt

Debt, in order of priority, consists of:

(in thousands)	March 30, 2013		December 29, 2012
Senior credit agreement:
Revolving credit facility	$	10,000	$	35,000
Term loan facility	288,750		296,250
	298,750		331,250
7.5% senior notes	365,000		365,000
	663,750		696,250
Less current portion, including borrowings under the revolving credit facility	25,000		50,000
Long-term debt	$	638,750	$	646,250

On June 29, 2012, the Company refinanced its previous senior secured credit agreement with a new senior secured credit agreement. The credit agreement provides for a $150,000,000 revolving credit facility ($50,000,000 of which was borrowed in connection with the refinancing) and a $300,000,000 term loan facility. The proceeds from the credit agreement were used to pay outstanding principal and interest under the previous credit agreement and loan acquisition costs of $6,228,000, which were capitalized and will be amortized over the life of the credit agreement. In connection with the refinancing, the Company wrote-off unamortized loan acquisition costs of $2,478,000 associated with the previous credit agreement. Interest rates under the credit agreement are, at the Company’s option, equal to either an alternate base rate or the Eurocurrency base rate, plus a specified margin.

Notes to condensed consolidated financial statements

(unaudited)

At March 30, 2013, the Company had $10,000,000 outstanding under the revolving credit facility and $140,000,000 available for borrowing. The revolving credit facility matures in June 2017. The Company intends to pay back outstanding borrowings under the revolving credit facility within the next twelve months and accordingly, has included these borrowings in “Current portion of debt” in the accompanying condensed consolidated balance sheets.

4. Fair Value of Financial Instruments

The Company’s financial instruments include cash and cash equivalents, accounts receivable, accounts payable, accrued liabilities and long-term debt. The carrying value of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximates their fair value due to the short-term maturities of these assets and liabilities. The carrying amount of borrowings under the senior secured credit agreement approximates fair value because the interest rates adjust to market interest rates. The fair value of the 7.5% senior notes, based on a quoted market price and classified as level one in the fair value hierarchy, was $391,463,000 at March 30, 2013.

5. Income Taxes

The income tax provision for the interim periods presented is computed at the effective rate expected to be applicable in each respective full year using the statutory rates on a country-by-country basis. Income tax expense recorded in the financial statements differs from the federal statutory income tax rate due to a variety of factors, including state income taxes, the mix of income between U.S. and foreign jurisdictions taxed at varying rates and changes in estimates of permanent differences and valuation allowances.

6. Pension Plans

The Company and its subsidiaries sponsor multiple defined benefit pension plans based in subsidiaries located outside of the United States. The following table provides the components of net periodic benefit cost:

	Three Months Ended
(in thousands)	March 30, 2013			March 31, 2012
Service cost	$	563		$	422
Interest cost	1,127			1,207
Expected return on plan assets	(191		)	(215		)
Amortization of prior service credit	(13		)	(13		)
Recognized net actuarial loss	432			119
Net periodic benefit cost	$	1,918		$	1,520

7. Environmental Matters

Environmental obligations are accrued when such expenditures are probable and reasonably estimable. The amount of liability recorded is based on currently available information, including the progress of remedial investigations, current status of discussions with regulatory authorities regarding the method and extent of remediation, presently enacted laws and existing technology. Accruals for estimated losses from environmental obligations are adjusted as further information develops or circumstances change. Costs of future expenditures for environmental obligations are not discounted to their present value. The Company does not currently anticipate any material loss in excess of the amounts accrued. However, the Company’s future remediation expenses may be affected by a number of uncertainties including, but not limited to, the difficulty in estimating the extent and method of remediation, the evolving nature of environmental regulations and the availability and application of technology. The Company does not expect the resolution of such uncertainties to have a material adverse effect on its consolidated financial position or liquidity. Recoveries of environmental costs from other parties are recognized as assets when receipt is deemed probable.

In connection with the acquisition of Membrana GmbH (“Membrana”) in 2002, the Company recorded a reserve for environmental obligations. The reserve provides for costs to remediate known environmental issues and operational upgrades which are required in order for the Company to remain in compliance with local regulations. The initial estimate and subsequent finalization of the reserve was included in the allocation of purchase price at the date of acquisition. The environmental reserve for the Membrana facility, which is denominated in euros, was $10,208,000 and $11,079,000 at March 30, 2013 and December 29, 2012, respectively. The Company anticipates the expenditures associated with the reserve will be

Notes to condensed consolidated financial statements

(unaudited)

made in the next twelve months. The reserve is included in “Accrued liabilities” in the accompanying condensed consolidated balance sheets.

The Company has indemnification agreements for certain environmental matters from Acordis A.G. (“Acordis”) and Akzo Nobel N.V. (“Akzo”), the prior owners of Membrana. Akzo originally provided broad environmental protections to Acordis with the right to assign such indemnities to Acordis’s successors. Akzo’s indemnifications relate to conditions existing prior to December 1999, which is the date that Membrana was sold to Acordis. In addition to the Akzo indemnification, Acordis provides separate indemnification of claims incurred from December 1999 through February 2002, the acquisition date. The Company receives indemnification payments under the indemnification agreements after expenditures are made against approved claims. At March 30, 2013 and December 29, 2012, the indemnification receivable, which is denominated in euros, was $11,189,000 and $11,542,000, respectively. The receivable is included in “Prepaid and other” in the accompanying condensed consolidated balance sheets.

8. Treasury Stock

On February 19, 2013, the Board of Directors authorized the repurchase of up to 4,000,000 shares of the Company’s common stock by December 31, 2013. As of March 30, 2013, the Company had repurchased 6,800 shares of common stock for $272,000. Additionally, in connection with the restricted stock grant on February 25, 2013, the Company withheld and repurchased 5,600 shares of common stock for $204,000 to satisfy certain foreign employees’ statutory withholding tax liability.

9. Related Party Transactions

The Company’s German subsidiary has a 33% equity investment in a patent and trademark service provider and a 25% equity investment in a research company. The investments are accounted for under the equity method of accounting and were $843,000 and $650,000 at March 30, 2013 and December 29, 2012, respectively. Charges from the affiliates for work performed were $266,000 and $327,000 for the three months ended March 30, 2013 and March 31, 2012, respectively. Amounts due to the affiliates were $84,000 and $239,000 at March 30, 2013 and December 29, 2012, respectively.

10. Noncontrolling Interest

In 2010, the Company formed a joint venture with Camel Group Co., Ltd (“Camel”), a leading battery manufacturer in China, to produce lead-acid battery separators primarily for Camel’s use. The joint venture, Daramic Xiangyang Battery Separator Co., Ltd. (“Daramic Xiangyang”), is located at Camel’s facility and owned 65% by the Company and 35% by Camel. During the three months ended March 30, 2013, the Company and Camel made equity contributions of $1,300,000 and $700,000, respectively, to fund capital expenditures.

In exchange for notes payable, Daramic Xiangyang purchased from Camel a building and from the Company certain production equipment that was previously located at the Company’s former facility in Potenza, Italy. The notes payable and related interest will be paid by Daramic Xiangyang using available free cash flow, as defined in the joint venture agreement. The building note payable to Camel has a principal balance of $5,910,000 at March 30, 2013 and December 29, 2012 and is included in “Other” non-current liabilities in the accompanying condensed consolidated balance sheets, and the equipment note payable to the Company eliminates in consolidation.

11. Commitments and Contingencies

Collective Bargaining Agreement

The Company’s employees at the Corydon, Indiana facility are represented under a labor union collective bargaining agreement. The collective bargaining agreement at the Corydon facility, covering approximately 3% of the Company’s workers, expires in August 2013.

Federal Trade Commission Litigation

On September 9, 2008, the Federal Trade Commission (the “FTC”) issued an administrative complaint against the Company alleging that the February 29, 2008 acquisition of Microporous Holding Corporation, the parent company of Microporous Products L.P. (“Microporous”), and the Company’s related actions have substantially lessened competition in North American markets for lead-acid battery separators. After challenging the complaint before an Administrative Law Judge of the FTC and

Table of Contents

Polypore International, Inc.

Notes to condensed consolidated financial statements

(unaudited)

subsequently before the Commissioners of the FTC, the Company was ordered to divest substantially all of the Microporous assets that were acquired in February 2008.

On January 28, 2011, the Company filed a petition with the U.S. Court of Appeals for the 11th Circuit to review the FTC’s November 5, 2010 order and opinion. On July 11, 2012, the 11th Circuit affirmed the FTC’s decision. The Company believes that this decision is inconsistent with the law and the facts presented at the hearing and that the Microporous acquisition is and will continue to be beneficial to its customers and the industry. Therefore, on January 15, 2013, the Company filed an appeal with the U.S. Supreme Court.

The Company believes that a final judicial resolution to the challenge by the FTC to the Microporous acquisition could take several months to a year. Although it is difficult to predict the outcome, timing or impact of this matter at this time, the Company believes that the final resolution will not have a material adverse impact on its business or financial condition.

The Company’s core energy storage business produces polymer-based membrane battery separators used in transportation, industrial and consumer electronics applications. The acquisition of the Microporous business extended the Company’s product portfolio into the niche, mature deep cycle market for rubber-based battery separators, with considerable overlap to customers it currently serves with other products. The Company does not believe that a required divestiture of all or a portion of the Microporous assets would significantly impact its core energy storage business or the long-term growth drivers impacting this business, including growth in Asia, demand for consumer electronics and growing demand for electric drive vehicles.

For the fiscal year ended December 29, 2012, the Microporous business represented approximately 10% of consolidated revenue and approximately 13% of consolidated operating income, including the facility that the Company completed and shifted production to in Feistritz, Austria post-acquisition. At December 29, 2012, Microporous assets were less than 5% of consolidated assets. The impact of a final resolution to this matter may be affected by a number of uncertainties, including, but not limited to, whether the Company is required to divest all or a portion of the Microporous assets, the timing of a potential divestiture, the proceeds of such a divestiture and the incremental growth in its core businesses. If the Company was required to divest all or a portion of the Microporous assets, it would intend to sell the assets at fair market value.

12. Stock-Based Compensation Plans

The Company offers stock-based compensation plans to attract, retain, motivate and reward key officers, non-employee directors and employees. Stock-based compensation expense was $4,467,000 and $4,270,000 for the three months ended March 30, 2013 and March 31, 2012, respectively. The income tax benefit related to stock-based compensation expense was $1,587,000 and $1,515,000 for the three months ended March 30, 2013 and March 31, 2012, respectively. Stock-based compensation expense includes costs associated with stock options and restricted stock and is classified as “Selling, general and administrative expenses” in the accompanying condensed consolidated statements of income.

The 2007 Stock Incentive Plan (“2007 Plan”) allows for the grant of stock options, restricted stock and other instruments for up to a total of 4,751,963 shares of common stock. On February 25, 2013, the Company granted 328,467 stock options and 85,461 shares of restricted stock under the 2007 Plan with an aggregate grant-date fair value of $9,248,000, to be recognized over the vesting period for each award. The stock options granted are time-vested options that vest annually in equal one-third installments and have 10-year terms and an exercise price of $36.42, the fair market value of the Company’s stock on the grant date.

The fair value of the options granted was estimated on the date of grant based on the Black-Scholes option pricing model with the following assumptions:

		February 25, 2013 Grant Assumptions
Expected term (years)		5.6
Risk-free interest rate		0.92%
Expected volatility		57.3%
Dividend yield		—

The potential expected term of the stock options ranges from the vesting period of the options (three years) to the contractual term of the options (ten years). The Company determines the expected term of the options based on historical experience,

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion of our financial condition and results of operations should be read together with our unaudited condensed consolidated financial statements and the related notes included elsewhere in this Quarterly Report on Form 10-Q and our audited consolidated financial statements and the related notes included in our Annual Report on Form 10-K for the fiscal year ended December 29, 2012.

Overview

We are a leading global high-technology filtration company that develops, manufactures and markets specialized microporous membranes used in separation and filtration processes. In fiscal 2012, we generated total net sales of $717.4 million. We operate in two primary businesses: energy storage, which includes the transportation and industrial segment and the electronics and EDVs segment, and separations media. The transportation and industrial and separations media segments represent approximately 75% of our total net sales and operate in stable, growing markets, have high recurring revenue bases and generate strong cash flows. In the electronics and EDVs segment, we have a key presence in the more established consumer electronics market and participate in the potentially larger and developing electric drive vehicle (“EDV”) and energy storage systems (“ESS”) markets where lithium is the disruptive technology. As described in more detail below, the long-term growth drivers for lithium batteries are positive, but we have and may continue to experience variability in the short term as these markets emerge.

Since 2009, we have made significant investments in capacity expansion projects, all of which were funded by internally generated cash and a $49.3 million grant from the U.S. Department of Energy. Cash flows from operations and lower capital expenditures position us to generate significant amounts of cash in 2013. In addition, the United States Federal Trade Commission (“FTC”) has ordered us to divest substantially all of the assets acquired in connection with the 2008 acquisition of Microporous Products L.P. (“Microporous”). We are pursuing our legal options and, at the same time, evaluating alternatives for these assets. If we divest all or a portion of these assets, we would intend to sell the assets at fair market value which would provide additional cash. During this period of substantial cash generation, we intend to maintain a total leverage ratio, defined in our credit agreement as the ratio of total indebtedness (total debt less cash on hand of up to $50.0 million) to adjusted EBITDA (as defined in our credit agreement and calculated in the liquidity and capital resources section), of approximately 3.0x, while also evaluating other alternatives for cash, including returning value to shareholders through share repurchases.

Energy Storage

In the energy storage business, our membrane separators are a critical performance component in lithium batteries, which are primarily used in consumer electronics and EDV applications, and lead-acid batteries, which are used globally in transportation and numerous industrial applications. We believe that the long-term growth drivers for the energy storage business — growth in Asia, demand for consumer electronics and growing demand for EDVs — are positive. The energy storage business is comprised of two reportable segments.

Electronics and EDVs. Lithium batteries are the power source in a wide variety of applications, including consumer electronics applications such as notebook computers, tablets, mobile phones and cordless power tools; EDVs; and emerging applications such as ESS. Demand for lithium batteries in consumer electronics is driven by the need for increased mobility. In EDV applications, demand is driven by the need to increase fuel efficiency to meet mileage standards in many countries such as the U.S. and China, the need to reduce CO2 emissions around the world but especially in Europe due to regulations, conversion from nickel metal hydride to lithium battery technology in hybrid vehicles due to greater energy and power density, concern in developed countries and emerging markets over future access to petroleum at stable prices, smog and pollution control, and the need to address increasing transportation needs in developing economies. Since late 2009, we have expanded capacity at our existing Charlotte, North Carolina and Ochang, South Korea facilities and built a new facility in Concord, North Carolina. Equipment installation for the Concord facility is substantially complete and production has started for portions of the facility. The remaining capacity at Concord will ramp up over time as the nascent market for EDVs develops.

We believe the long-term demand drivers for our products—consumer demand for mobility, regulations for fuel efficiency and CO2 emissions, conversion to lithium technology in hybrids, concerns about access to petroleum, efforts to reduce pollution, and increasing transportation needs in developing countries—remain fully intact. While consumer electronics applications have attractive long-term market growth trends, EDV and eventually ESS applications have the potential to be much larger markets. Based on industry forecasts and industry studies, unit sales of lithium batteries for EDV applications are expected to grow at a compound annual growth rate of greater than 40% over the next five years. We believe lithium battery separator growth will exceed battery unit sales growth because the trend towards larger batteries will require the use of more separator in each battery. Industry forecasts also predict EDV sales to be 5% or more of new car sales within the next five years. If 5% of new car sales were EDVs, we believe the entire lithium battery separator market would virtually double in total size. Based on our current customer base, if only a portion of these industry forecasts materialize, we believe we will completely utilize our current production capacity. We believe the electrification of the worldwide fleet of vehicles is just beginning, from hybrids to

plug-ins to full battery electric vehicles, including automobiles, buses, taxis and commercial fleet vehicles. Hybrids are selling well and regulations around the world are driving development and introductions. New hybrids are coming to market and some high-separator content vehicles have just been introduced in Europe. We believe our dry process products continue to be the preferred product in large format lithium-ion batteries for EDVs and ESS. We are currently working with existing and new customers on next-generation batteries, which is important considering the long lead times required to become qualified for EDV applications. EDV and ESS are emerging market applications and are being adopted around the world in many forms. We believe the factors that influenced our decision to expand capacity remain valid, and we continue to expect significant sales growth as the EDV market develops and as ESS experiences more meaningful adoption. Although the long-term growth drivers are positive for these applications, short-term fluctuations in demand can be expected in the early stages of adoption while initial penetration rates are low. Given the high-separator content for these applications, and the potential size of these markets, small changes in end-market demand can have a significant impact on our business.

Transportation and industrial. In the lead-acid battery market, the high proportion of aftermarket replacement sales and the steady growth of the worldwide fleet of motor vehicles provide us with a growing recurring revenue base in lead-acid battery separators. Worldwide demand for lead-acid battery separators is expected to continue to grow at slightly more than annual economic growth. The Asia-Pacific region is the fastest growing market for lead-acid battery separators. Growth in this region is driven by the increasing penetration of automobile ownership, growth in industrial and manufacturing sectors, export incentives and ongoing conversion to the polyethylene-based membrane separators we produce. We are meeting growing demand in this region by investing in Asia and exporting from our U.S. and European facilities. Our investments in Asia have included completing three capacity expansions at our Prachinburi, Thailand facility, the most recent of which started production in 2012; acquiring battery separator manufacturing assets and subsequently expanding our operations in Bangalore, India; acquiring a production facility in Tianjin, China; establishing an Asian Technical Center in Thailand; and entering into a joint venture with a customer, Camel Group Co., Ltd. (“Camel”), to produce lead-acid battery separators in Xiangyang, China, primarily for Camel’s use.

Separations Media

In the separations media business, our filtration membranes and modules are used in healthcare and high-performance filtration and specialty applications. We believe that the separations media business will continue to benefit from continued growth in demand for higher levels of purity in a growing number of applications. The separations media business is a reportable segment.

For healthcare applications, we produce membranes used in blood filtration applications for hemodialysis, blood oxygenation and plasmapheresis. Growth in demand for hemodialysis membranes is driven by the increasing worldwide population of end-stage renal disease patients. We believe that conversion to single-use dialyzers and increasing treatment frequency will result in additional dialyzer market growth. In late 2011, we completed the expansion of our PUREMA® hemodialysis membrane production capacity to support future market growth.

For filtration and specialty applications, we produce a wide range of membranes and membrane-based elements for micro-, ultra- and nanofiltration and gasification/degasification of liquids. Micro-, ultra- and nanofiltration membrane element market growth is being driven by several factors, including end-market growth in applications such as water treatment and pharmaceutical processing, displacement of conventional filtration media by membrane filtration due to membranes’ superior cost and performance attributes, and increasing purity requirements in industrial and other applications.

Critical accounting policies

Critical accounting policies are those accounting policies that can have a significant impact on the presentation of our financial condition and results of operations, and that require the use of complex and subjective estimates based on past experience and management’s judgment. Because of the uncertainty inherent in such estimates, actual results may differ from these estimates. These policies are critical to the understanding of our operating results and financial condition and include policies related to the allowance for doubtful accounts, impairment of intangibles and goodwill, pension benefits, environmental matters and repairs and maintenance. For a discussion of each of these policies, please see the discussion entitled “Critical Accounting Policies” under Item 7 — Management’s Discussion and Analysis of Financial Condition and Results of Operations in our Annual Report on Form 10-K for the year ended December 29, 2012.

Comparison of the three months ended March 30, 2013 with the three months ended March 31, 2012

Net sales. Net sales for the three months ended March 30, 2013 were $163.5 million, a decrease of $10.2 million, or 5.9%, from the same period in the prior year, as higher sales in the transportation and industrial and separations media segments were more than offset by lower sales in the electronics and EDVs segment. The impact of foreign currency translation was not significant.

Gross profit. Gross profit was $54.8 million, a decrease of $16.2 million, or 22.8%, from the same period in the prior year. Gross profit as a percent of net sales was 33.5% for the three months ended March 30, 2013 compared to 40.9% for the three months ended March 31, 2012. The decrease in consolidated gross profit and gross profit margin was primarily due to lower sales and higher costs associated with our capacity expansions in the electronics and EDVs segment relative to the prior year.

Selling, general and administrative expenses. Selling, general and administrative expenses decreased $2.5 million for the three months ended March 30, 2013 compared to the prior year, primarily due to a $2.0 million decrease in performance-based incentive compensation expense and $1.1 million lower amortization expense. Selling, general and administrative expenses were 19.2% of consolidated net sales for the three months ended March 30, 2013 and 19.5% for the same period in the prior year.

Segment operating income. Segment operating income, which excludes stock-based compensation and certain non-recurring and other costs, was $28.3 million, a decrease of $13.7 million, or 32.6%, from the same period in the prior year. Segment operating income as a percent of net sales was 17.3% for the three months ended March 30, 2013 compared to 24.2% for the three months ended March 31, 2012. The decrease in segment operating income and segment operating income margin was the result of lower sales and higher costs associated with our capacity expansions in the electronics and EDVs segment relative to the prior year.

Interest expense. Interest expense for the three months ended March 30, 2013 increased by $1.0 million from the same period in the prior year, primarily resulting from a decrease in capitalized interest as our capacity expansion projects are now substantially complete.

Income taxes. Income tax expense for the interim periods presented is computed at the effective rate expected to be applicable in each respective full year using the statutory rates on a country-by-country basis. The effective tax rate was 30.4% for the three months ended March 30, 2013 compared to 32.7% for the same period in the prior year. The mix of earnings between the tax jurisdictions has the most significant impact on the effective tax rate. Each tax jurisdiction has its own set of tax laws and tax rates, and income earned by our subsidiaries is taxed independently by these various jurisdictions. Currently, the applicable statutory income tax rates in the jurisdictions in which we operate range from 0% to 39%.

Comparison of the three months ended March 30, 2013 with the three months ended March 31, 2012

Net sales. Net sales for the three months ended March 30, 2013 were $24.4 million, a decrease of $18.0 million, or 42.5%, from the same period in the prior year. The decrease was due primarily to lower volumes, but was also impacted by price/product mix. Net sales were down $15.8 million, or 37.3%, due to lower volumes resulting from weak demand and some customers reducing inventory associated with their fiscal year-ends. Net sales decreased by $2.2 million, or 5.2%, due to price/product mix. Price/product mix includes the impact of volume-based price declines where expected volumes did not materialize but the lower price was honored. During the second quarter of 2013, we increased prices to address this issue.

Based on improved order patterns in March 2013 that continued into April, the ramp-up of two battery and EDV production facilities and new vehicle launches, we expect second quarter sales to be higher than in the first quarter.

Segment operating income (loss). Segment operating loss was $2.5 million for the three months ended March 30, 2013 compared to segment operating income of $16.8 million for the same period in the prior year. The segment operating loss was due to lower sales volume and higher costs associated with our capacity expansions relative to the prior year.

Since 2009, we have completed five separate capacity expansions and added the fixed costs required to operate the new capacity. Excluding the final phase of expansion at Concord, which will be qualified and ramped-up as demand develops, we have total production capacity sufficient to generate approximately $400.0 million in annual lithium battery separator sales, depending on the mix of products and grades produced. Based on annualized sales in the first quarter of 2013, our current production capacity in terms of sales was approximately 25%.

The key driver of profitability is sales and the resulting benefit of higher production volumes. Because this is a low variable production cost business, operating income and operating income margins fluctuate primarily based on production volumes and the application of fixed costs to those production volumes. When sales volumes increase, operating income margins increase as the production cost per unit is lower due to the allocation of fixed costs to more units of production. Conversely, when sales volumes decline, operating income margins decrease as the production cost per unit is higher due to the allocation of fixed costs to less units of production. Because of this, we expect segment operating income and segment operating income margins to improve as sales volumes increase and the costs associated with our capacity expansions are allocated to more units of production.

Transportation and Industrial

Comparison of the three months ended March 30, 2013 with the three months ended March 31, 2012

Net sales. Net sales for the three months ended March 30, 2013 were $93.7 million, an increase of $7.5 million, or 8.7%, from the same period in the prior year due to growth in Asia and a more typical battery build season associated with colder winter weather in North America and Europe.

Segment operating income. Segment operating income was $21.3 million, an increase of $1.3 million, or 6.5%, from the same period in the prior year due to higher sales. Segment operating income as a percent of net sales was 22.7% for the three months ended March 30, 2013, which is consistent with 23.2% for the same period in the prior year.

Separations Media

Comparison of the three months ended March 30, 2013 with the three months ended March 31, 2012

Net sales. Net sales for the three months ended March 30, 2013 were $45.4 million, an increase of $0.3 million, or 0.7%, from the same period in the prior year. The increase consisted of higher healthcare sales, offset by a decline in filtration and specialty product sales due to economic weakness in microelectronics.

Segment operating income. Segment operating income was $15.5 million, an increase of $1.6 million, or 11.5%, from the same period in the prior year. Segment operating income as a percent of net sales was 34.1% for the three months ended March 30, 2013 compared to 30.8% for the three months ended March 31, 2012. The increase in segment operating income margin was due to production timing and efficiencies. Segment operating income margins can fluctuate between quarters due to production timing and mix, but are expected to be relatively consistent to the prior year on an annual basis.

Corporate and other costs

Corporate and other costs include costs associated with the corporate office and other costs that are not allocated to the reporting segments for segment reporting purposes, including amortization of identified intangible assets and performance-based incentive compensation.

Comparison of the three months ended March 30, 2013 with the three months ended March 31, 2012

Corporate and other costs for the three months ended March 30, 2013 were $6.0 million, compared to $8.7 million for the three months ended March 31, 2012. The decrease was primarily due to lower performance-based incentive compensation expense and a decline in amortization expense as certain intangible assets became fully amortized in the second quarter of 2012.

Foreign Operations

As of March 30, 2013, we manufacture our products at 16 strategically located facilities in the United States, Europe and Asia. Net sales from foreign locations were $106.3 million (65.0% of consolidated sales) and $111.7 million (64.3% of consolidated sales) for the three months ended March 30, 2013 and March 31, 2012, respectively. The majority of sales from U.S. production facilities are attributable to the electronics and EDVs segment, where we primarily produce in the U.S. for customers located in Asia. The majority of sales from foreign production facilities are attributable to the transportation and industrial and separations media segments. In the transportation and industrial segment, we have production facilities in the U.S., Europe and Asia and generally produce in the same geographic region that we sell, though we do export some production from U.S. and European facilities to meet growing demand in Asia. In the separations media segment, the majority of production is at our manufacturing facility in Germany and sales are made to customers worldwide. Operating results generated by production facilities within business segments was not significantly impacted by differences in economic, regulatory, geographic or other competitive factors.

Typically, we sell our products in the currency of the country where the manufacturing facility that produces the product is located. Sales to foreign customers are subject to numerous additional risks, including the impact of foreign government regulations, currency fluctuations, political uncertainties and differences in business practices. There can be no assurance that foreign governments will not adopt regulations or take other actions that would have a direct or indirect adverse impact on our business or market opportunities within such governments’ countries. Furthermore, there can be no assurance that the political, cultural and economic climate outside the United States will be favorable to our operations and growth strategy.

Liquidity and capital resources

Cash and cash equivalents decreased by $1.7 million during the three months ended March 30, 2013, as cash generated from operations was used to repay borrowings under the senior secured credit agreement and fund capital expenditures.

Operating activities. Net cash provided by operating activities was $36.2 million in the three months ended March 30, 2013, primarily consisting of cash generated from operations of $26.2 million and a net decrease in working capital of $9.2 million. Accounts receivable decreased due to lower sales as compared to the fourth quarter of 2012. Days sales outstanding is consistent with the prior year, and we have not experienced significant changes in accounts receivable aging or customer payment terms and believe that we have adequately provided for potential bad debts. The increase in inventory was due to higher levels of work-in-process/finished goods in the separations media segment due to production timing. Total work-in-process/finished goods inventory increased from 59 days sales in ending inventory in the fourth quarter of 2012 to 70 days in the first quarter of 2013. We produce inventory to meet expected future customer demand, which is based on a number of factors, including discussions with customers, customer forecasts and industry and economic trends. Inventory is generally not subject to obsolescence and does not have a shelf life, and we do not believe there is a significant risk of inventory impairment. Accounts payable and accrued liabilities increased primarily due to timing of payments.

Investing activities. In the three months ended March 30, 2013, total capital expenditures were $6.2 million compared to $45.4 million for the same period in the prior year. We have substantially completed our capacity expansion projects and currently estimate capital expenditures for fiscal 2013 to be approximately $50.0 million. As of March 30, 2013, we had $155.5 million of construction in progress, primarily related to the expansions in the electronics and EDVs segment, portions of which will be qualified and ramped up over time as market demand develops.

Financing activities. During the three months ended March 30, 2013, financing activities consisted primarily of repayments of borrowings under the revolving credit facility of $25.0 million and scheduled principal payments under our credit agreement of $7.5 million.

We intend to fund our ongoing operations with cash on hand, cash generated by operations and borrowings under the senior secured credit agreement. As of March 30, 2013, approximately 70% of our cash and cash equivalents were held by foreign subsidiaries. There were no significant restrictions on our ability to transfer funds with and among subsidiaries, or any material adverse tax consequences that would impact our ability to transfer funds held by foreign subsidiaries to the U.S.

Cash flows from operations and lower capital expenditures position us to generate significant amounts of cash in 2013. In addition, the FTC has ordered us to divest substantially all of the assets acquired in connection with the 2008 acquisition of Microporous. We are pursuing our legal options and, at the same time, evaluating alternatives for these assets. If we divest all or a portion of these assets, we would intend to sell the assets at fair market value which would provide additional cash. During this period of substantial cash generation, we intend to maintain a total leverage ratio, defined in our credit agreement as the ratio of total indebtedness (total debt less cash on hand of up to $50.0 million) to adjusted EBITDA (as defined in our credit agreement and calculated below), of approximately 3.0x, while also evaluating other alternatives for cash, including returning value to shareholders through share repurchases. On February 19, 2013, the Board of Directors authorized the repurchase of up to 4.0 million shares of our common stock by December 31, 2013. As of March 30, 2013, we had repurchased 6,800 shares of common stock for $0.3 million. The timing, price and volume of future repurchases will be based on market conditions, relevant securities laws and other factors. The stock repurchases may be made from time to time on the open market or in privately negotiated transactions. The stock repurchase program does not require us to repurchase any specific number of shares, and we may terminate the repurchase program at any time. The cash proceeds received from any potential divestiture of all or a portion of the Microporous assets in Piney Flats, Tennessee, and Feistritz, Austria, may be a factor in the amount of shares repurchased.

Our senior secured credit agreement provides for a $300.0 million term loan facility ($288.8 million outstanding at March 30, 2013) and a $150.0 million revolving credit facility ($10.0 million outstanding at March 30, 2013). At March 30, 2013, the Company had $140.0 million of borrowings available under the revolving credit facility. The term loan facility and the revolving credit facility mature in June 2017. Because we intend to pay back outstanding borrowings under the revolving credit facility within the next twelve months, we have classified these borrowings as current liabilities.

Interest rates under the senior secured credit agreement are, at our option, equal to either an alternate base rate or Eurocurrency base rate plus a specified margin. At March 30, 2013, the interest rate on borrowings under the senior secured credit agreement was 2.96%.

Under the credit agreement, we are required to maintain a maximum ratio of indebtedness to adjusted EBITDA and a minimum ratio of adjusted EBITDA to cash interest expense. Adjusted EBITDA, as defined under the senior secured credit agreement, was as follows:

(in millions)
Adjusted EBITDA	$	200.9
Interest expense, net (1)	$	36.1
Actual interest coverage ratio	5.56x
Required minimum interest coverage ratio	3.00x

(1) Calculated as cash interest expense, as defined under the senior secured credit agreement, for the twelve months ended March 30, 2013.

The senior secured credit agreement contains certain restrictive covenants which, among other things, limit the incurrence of additional indebtedness, investments, dividends, transactions with affiliates, asset sales, acquisitions, mergers and consolidations, prepayments of other indebtedness, liens and encumbrances, and other matters customarily restricted in such agreements. The agreement also contains certain customary events of default, subject to grace periods, as appropriate.

The 7.5% senior notes mature on November 15, 2017 and are guaranteed by most of our existing and future domestic restricted subsidiaries, subject to certain exceptions. Except under certain circumstances, the 7.5% senior notes do not require principal payments prior to their maturity in 2017. Interest on the 7.5% senior notes is payable semi-annually on May 15 and November 15. The 7.5% senior notes contain customary covenants and events of default, including covenants that limit our ability to incur debt, pay dividends and make investments.

Future debt service payments are expected to be paid out of cash flows from operations, borrowings on our revolving credit facility and future refinancing of our debt. Our cash interest requirements for the next twelve months are estimated to be $37.0 million.

We believe we have sufficient liquidity to meet our cash requirements over both the short (next twelve months) and long term (in relation to our debt service requirements). In evaluating the sufficiency of our liquidity, we considered cash on hand, expected cash flow to be generated from operations and available borrowings under our senior secured credit agreement compared to our anticipated cash requirements for debt service, working capital, cash taxes, capital expenditures and funding requirements for long-term liabilities. We anticipate that our cash on hand and operating cash flow, together with borrowings under the revolving credit facility, will be sufficient to meet our anticipated future operating expenses, capital expenditures and

debt service obligations as they become due for at least the next twelve months. However, our ability to make scheduled payments of principal, to pay interest on or to refinance our indebtedness and to satisfy our other debt obligations will depend upon our future operating performance, which will be affected by general economic, financial, competitive, legislative, regulatory, business and other factors beyond our control. See “Item 1A. Risk Factors” in our most recent Annual Report on Form 10-K.

From time to time, we may explore additional financing methods and other means to lower our cost of capital, which could include equity or debt financings and the application of the proceeds therefrom to the repayment of bank debt or other indebtedness. In addition, in connection with any future acquisitions, we may require additional funding which may be provided in the form of additional debt or equity financing or a combination thereof. There can be no assurance that any additional financing will be available to us on acceptable terms or at all.

Environmental matters

Environmental obligations are accrued when such expenditures are probable and reasonably estimable. The amount of liability recorded is based on currently available information, including the progress of remedial investigations, current status of discussions with regulatory authorities regarding the method and extent of remediation, presently enacted laws and existing technology. Accruals for estimated losses from environmental obligations are adjusted as further information develops or circumstances change. Costs of future expenditures for environmental obligations are not discounted to their present value. We do not currently anticipate any material loss in excess of the amounts accrued. Future remediation expenses may be affected by a number of uncertainties including, but not limited to, the difficulty in estimating the extent and method of remediation, the evolving nature of environmental regulations and the availability and application of technology. We do not expect the resolution of such uncertainties to have a material adverse effect on our consolidated financial position or liquidity. Recoveries of environmental costs from other parties are recognized as assets when their receipt is deemed probable.

In connection with the acquisition of Membrana GmbH (“Membrana”) in 2002, we recorded a reserve for environmental obligations. The reserve provides for costs to remediate known environmental issues and operational upgrades which are required in order for us to remain in compliance with local regulations. The initial estimate and subsequent finalization of the reserve was included in the allocation of purchase price at the date of acquisition. The environmental reserve for the Membrana facility, which is denominated in euros, was $10.2 million at March 30, 2013. We anticipate the expenditures associated with the reserve will be made in the next twelve months.

We have indemnification agreements for certain environmental matters from Acordis A.G. (“Acordis”) and Akzo Nobel N.V. (“Akzo”), the prior owners of Membrana. Akzo originally provided broad environmental protections to Acordis with the right to assign such indemnities to Acordis’s successors. Akzo’s indemnifications relate to conditions existing prior to December 1999, which is the date that Membrana was sold to Acordis. In addition to the Akzo indemnification, Acordis provides separate indemnification of claims incurred from December 1999 through February 2002, the acquisition date. We will receive indemnification payments under the indemnification agreements after expenditures are made against approved claims. At March 30, 2013, the indemnification receivable, which is denominated in euros, was $11.2 million.

Off-Balance Sheet Arrangements

We are not a party to any off-balance sheet arrangements that have, or are reasonably likely to have, a material current or future effect on our financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to various market risks, which are potential losses arising from adverse changes in market rates and prices, such as interest rates and foreign exchange fluctuations. We do not enter into derivatives or other financial instruments for trading or speculative purposes.

Interest rate risk

At March 30, 2013, we had fixed rate debt of $365.0 million and variable rate debt of $298.8 million. To reduce the interest rate risk inherent in our variable rate debt, we may utilize interest rate derivatives. As of March 30, 2013, there were no outstanding interest rate derivatives. The pre-tax earnings and cash flow impact resulting from a 100 basis point increase in interest rates on our variable rate debt, holding other variables constant, would be $3.0 million per year.

Table of Contents

Currency risk

Outside of the United States, we maintain assets and operations in Europe and Asia. The results of operations and financial position of our foreign operations are principally measured in their respective currency and translated into U.S. dollars. As a result, exposure to foreign currency fluctuations exists. The reported income of these subsidiaries will be higher or lower depending on a weakening or strengthening of the U.S. dollar against the respective foreign currency. Our subsidiaries and affiliates also purchase and sell products and services in various currencies. As a result, we may be exposed to cost increases relative to the local currencies in the markets in which we sell. Because the percentage of our sales in foreign currencies differs from the percentage of our costs in foreign currencies, a change in the relative value of the U.S. dollar could have a disproportionate impact on our sales compared to our costs, which could impact our margins. A portion of our assets are based in our foreign locations and are translated into U.S. dollars at foreign currency exchange rates in effect as of the end of each period, with the effect of such translation reflected in accumulated other comprehensive income (loss). Accordingly, our consolidated shareholders’ equity will fluctuate depending upon the weakening or strengthening of the U.S. dollar against the respective foreign currency, primarily the euro.

The dollar/euro exchange rates used in our financial statements for the periods ended as set forth below were as follows:

	March 30, 2013	March 31, 2012
Period end rate	1.2820	1.3339
Period average rate for the three months ended	1.3206	1.3099

Our strategy for management of currency risk relies primarily on conducting our operations in a country’s respective currency and may, from time to time, involve foreign currency derivatives. As of March 30, 2013, we did not have any foreign currency derivatives outstanding.

Item 4. Controls and Procedures

An evaluation of the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) or 15d-15(e) promulgated under the Exchange Act) was performed under the supervision, and with the participation of, our management, including our Chief Executive Officer and Chief Financial Officer. Our disclosure controls are designed to ensure that information required to be disclosed in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission. Based upon our evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of March 30, 2013 to ensure that information required to be disclosed in the reports that we file under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms, and is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

During the three months ended March 30, 2013, there has been no change in our internal control over financial reporting (as defined in Rules 13a-15(f) or 15d-15(f) promulgated under the Exchange Act) that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II — OTHER INFORMATION

Item 1. Legal Proceedings

On September 9, 2008, the Federal Trade Commission (the “FTC”) issued an administrative complaint against us alleging that our February 29, 2008 acquisition of Microporous Holding Corporation, the parent company of Microporous Products L.P. (“Microporous”), and our related actions have substantially lessened competition in North American markets for lead-acid battery separators. After challenging the compliant before an Administrative Law Judge of the FTC and subsequently before the Commissioners of the FTC, we were ordered to divest substantially all of the Microporous assets that were acquired in February 2008.

On January 28, 2011, we filed a petition with the U.S. Court of Appeals for the 11th Circuit to review the FTC’s November 5, 2010 order and opinion. On July 11, 2012, the 11th Circuit affirmed the FTC’s decision. We believe that this decision is inconsistent with the law and the facts presented at the hearing and that the Microporous acquisition is and will continue to be beneficial to our customers and the industry. Therefore, on January 15, 2013, we filed an appeal with the U.S. Supreme Court.

We believe that a final judicial resolution to the challenge by the FTC to the Microporous acquisition could take several months to a year. Although it is difficult to predict the outcome, timing or impact of this matter at this time, we believe that the final resolution will not have a material adverse impact on our business or financial condition.

Table of Contents

Our core energy storage business produces polymer-based membrane battery separators used in transportation, industrial and consumer electronics applications. The acquisition of the Microporous business extended our product portfolio into the niche, mature deep cycle market for rubber-based battery separators, with considerable overlap to customers we currently serve with other products. We do not believe that a required divestiture of all or a portion of the Microporous assets would significantly impact our core energy storage business or the long-term growth drivers impacting this business, including growth in Asia, demand for consumer electronics and growing demand for electric drive vehicles.

For the fiscal year ended December 29, 2012, the Microporous business represented approximately 10% of consolidated revenue and approximately 13% of consolidated operating income, including the facility that we completed and shifted production to in Feistritz, Austria post-acquisition. At December 29, 2012, Microporous assets were less than 5% of consolidated assets. The impact of a final resolution to this matter may be affected by a number of uncertainties, including, but not limited to, whether we are required to divest all or a portion of the Microporous assets, the timing of a potential divestiture, the proceeds of such a divestiture and the incremental growth in our core businesses. If we were required to divest all or a portion of the Microporous assets, we would intend to sell the assets at fair market value.
