1.Basis of Presentation

The condensed consolidated financial statements as of  June 30, 2007 and 2006 of Packaging Corporation of America (“PCA” or the “Company”) and for the three- and six-month periods then ended are unaudited but include all adjustments (consisting only of normal recurring adjustments) that management considers necessary for a fair presentation of such financial statements. These financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with Article 10 of SEC Regulation S-X. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete audited financial statements. Operating results for the period ended June 30, 2007 are not necessarily indicative of the results that may be expected for the year ending December 31, 2007. These condensed consolidated financial statements should be read in conjunction with PCA’s Annual Report on Form 10-K for the year ended December 31, 2006. The condensed consolidated financial statements as of June 30, 2006 have been restated for the adoption of FASB Staff Position (“FSP”) No. AUG AIR-1, “Accounting for Planned Major Maintenance Activities.” The Company adopted this FSP on January 1, 2007, which required prior year financial statements to be restated to account for the impact of this FSP as if it had been adopted on January 1, 2006. See Note 2, Summary of Accounting Policies—Recent Accounting Pronouncements for additional information.

2.Summary of Accounting Policies

Basis of Consolidation

The accompanying condensed consolidated financial statements of PCA include all majority-owned subsidiaries. All intercompany transactions have been eliminated. The Company has one joint venture that is accounted for under the equity method.

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts in the financial statements and the accompanying notes. Actual results could differ from those estimates.

Revenue Recognition

The Company recognizes revenue as title to the products is transferred to customers. Shipping and handling billings to a customer are included in net sales. Shipping and handling costs are included in cost of sales. In addition, the Company offers volume rebates to certain of its customers. The total cost of these programs is estimated and accrued as a reduction to net sales at the time of the respective sale.

Segment Information

PCA is engaged in one line of business: the integrated manufacture and sale of packaging materials, boxes and containers for industrial and consumer markets. No single customer accounts for more than 10% of total net sales.

Reclassifications

Prior year’s financial statements have been reclassified where appropriate to conform with the current year presentation.

Recent Accounting Pronouncements

In February 2007, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standards (“SFAS”) No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities—Including an Amendment of FASB Statement No. 115.” This Statement permits entities to choose to measure many financial instruments and certain other items at fair value. Most of the provisions of SFAS No. 159 apply only to entities that elect the fair value option. However, the amendments to SFAS No. 115, “Accounting for Certain Investments In Debt and Equity Securities,” apply to all entities with available-for-sale and trading securtities. SFAS No. 159 is effective as of the beginning of an entity’s first fiscal year that begins after November 15, 2007. Early adoption is permitted as of the beginning of a fiscal year that begins on or before November 15, 2007, provided that an entity also elects to apply the provisions of SFAS No. 157, “Fair Value Measurements.” The Company is assessing SFAS No. 159 and has not yet determined the impact that the adoption of SFAS No. 159 will have on its results of operations.

In September 2006, the FASB issued SFAS No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans—an amendment of FASB Statements No. 87, 88, 106 and 132(R).” SFAS No. 158 requires plan sponsors of defined benefit pension and other postretirement benefit plans (collectively, “postretirement benefit plans”) to recognize the funded status of their postretirement benefit plans in the statement of financial position, measure the fair value of plan assets and benefit

obligations as of the date of the fiscal year end statement of financial position, and provide additional disclosures. These requirements were effective for fiscal years ending after December 15, 2006, with the exception of the requirement to measure plan assets and benefit obligations as of the plan sponsor’s fiscal year-end. This requirement is effective for fiscal years ending after December 15, 2008. On December 31, 2006, the Company adopted the recognition and disclosure provisions of SFAS No. 158. The Company is assessing the remaining provision of SFAS No. 158 to determine the impact that the adoption of those provisions may have on its results of operations.

In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements.” SFAS No. 157 clarifies the principle that fair value should be based on the assumptions market participants would use when pricing an asset or liability and establishes a fair value hierarchy that prioritizes the information used to develop those assumptions. Under the standard, fair value measurements would be separately disclosed by level within the fair value hierarchy. This statement is effective for fiscal years beginning after November 15, 2007. The Company is assessing SFAS No. 157 and has not yet determined the impact that the adoption of SFAS No. 157 will have on its results of operations.

In September 2006, the FASB issued FSP No. AUG AIR-1, “Accounting for Planned Major Maintenance Activities.” This FSP prohibits the use of the accrue-in-advance method of accounting for planned major maintenance activities in annual and interim financial reporting periods and is effective for fiscal years beginning after December 15, 2006. Prior to the adoption of this FSP, the Company determined its planned maintenance costs for the year and amortized these costs ratably throughout the year. On January 1, 2007, the Company began accounting for its planned major maintenance activities in accordance with FSP No. AUG AIR-1 using the deferral method. The implementation of FSP No. AUG AIR-1 will not have any impact on the Company’s year end financial position or full year results of operations and cash flows as all maintenance costs incurred have been and continue to be expensed in the fiscal year in which the maintenance activity occurs. In accordance with FSP No. AUG AIR-1, the Company’s financial position, results of operations and cash flows for each quarter of 2006 were adjusted to apply the FSP retrospectively. The following financial statement line items as of and for the three- and six-month period ended June 30, 2006 were adjusted as follows:

2.Summary of Accounting Policies (Continued)

In June 2006, the FASB issued FASB Interpretation (“FIN”) No. 48, “Accounting for Uncertainty in Income Taxes,” an interpretation of SFAS No. 109, “Accounting for Income Taxes,” to create a single model to address accounting for uncertainty in tax positions. FIN No. 48 clarifies the accounting for income taxes by prescribing a minimum recognition threshold a tax position is required to meet before being recognized in the financial statements. FIN No. 48 also provides guidance on derecognition, measurement, classification, interest and penalties, accounting in interim periods, disclosure, and transition. FIN No. 48 is effective for fiscal years beginning after December 15, 2006. The Company adopted FIN No. 48 on January 1, 2007.

As a result of the implementation of FIN No. 48, PCA recognized a $5.1 million decrease to reserves for uncertain tax positions and an increase to the beginning balance of retained earnings on the condensed consolidated balance sheet. After adoption on January 1, 2007, the Company had $9.1 million total gross unrecognized tax benefits. Of this total, $7.1 million (net of the federal benefit on state issues and interest) would impact its effective tax rate if recognized. At June 30, 2007, PCA had $7.9 million of unrecognized tax benefits.

PCA’s continuing practice is to recognize interest and penalties related to uncertain tax positions in income tax expense. After adoption of FIN No. 48 on January 1, 2007, the Company had $0.6 million accrued for interest and no reserve for penalties. During the six month period ended June 30, 2007, PCA recorded $0.2 million for interest in its statement of operations, increasing the accrual for interest to $0.8 million at June 30, 2007.

PCA and its subsidiaries are subject to U.S. federal income taxes, as well as income taxes of multiple state and city jurisdictions. The federal income tax return for 2004 is currently under examination, and a federal examination of the tax year 2002 has been concluded. The tax years 2001 and 2003-2006 remain open to federal examination. In major state jurisdictions, tax years 2002-2006 remain open for examination.

3.Earnings Per Share

The following table sets forth the computation of basic and diluted income per common share for the periods presented. Basic and diluted income per common share for the six month period ended June 30, 2006 increased $0.02 and $0.01, respectively, due to the restatement of the Company’s results of operations as a result of the adoption of FSP No. AUG AIR-1. Basic and diluted income per common share for the three month period ended June 30, 2006 did not change as a result of the adoption of this FSP.

4.Stock-Based Compensation

In October 1999, the Company adopted a long-term equity incentive plan which provides for grants of stock options, stock appreciation rights, restricted stock and performance awards to directors, officers and employees of PCA, as well as others who engage in services for PCA. Option awards granted to officers, employees and directors have contractual lives of seven or ten years. Options granted to officers and employees vest ratably over a three- or four-year period, whereas options granted to directors vest immediately. The plan, which will terminate on October 19, 2009, provides for the issuance of up to 6,550,000 shares of common stock. As of June 30, 2007, options or restricted stock for 5,826,164 shares

4.Stock-Based Compensation (Continued)

have been granted, net of forfeitures. Forfeitures are added back to the pool of shares of common stock available to be granted at a future date.

Effective January 1, 2006, the Company adopted the fair value recognition provisions of SFAS No. 123(R), “Share-Based Payment,” using the modified-prospective-transition method. Under that transition method, stock compensation cost recognized subsequent to January 1, 2006 includes: (a) compensation cost for all share-based payments granted prior to, but not vested, as of January 1, 2006, based on the grant date fair value estimated in accordance with the original provisions of SFAS No. 123, and (b) compensation cost for all share-based payments granted subsequent to January 1, 2006, based on the grant date fair value estimated in accordance with the provisions of SFAS No. 123(R). Compensation expense for both stock options and restricted stock recognized in the condensed consolidated statements of income for the three- and six- month periods ended June 30, 2007 and 2006 was as follows:

	Three Months Ended June 30,						Six Months Ended June 30,
(In thousands)	2007			2006			2007			2006
Stock options	$	(718	)	$	(1,104	)	$	(1,408	)	$	(1,891	)
Restricted stock	(2,344		)	(592		)	(3,174		)	(1,162		)
Impact on income before income taxes	(3,062		)	(1,696		)	(4,582		)	(3,053		)
Income tax benefit	1,193			663			1,786			1,193
Impact on net income	$	(1,869	)	$	(1,033	)	$	(2,796	)	$	(1,860	)

The Company uses the Black-Scholes-Merton option-pricing model to estimate the fair value of each option grant as of the date of grant. Expected volatilities are based on historical volatility of the Company’s common stock. The expected life of the option is estimated using historical data pertaining to option exercises and employee terminations. Separate groups of employees that have similar historical exercise behavior are considered separately for estimating the expected life. The risk-free interest rate is based on U.S. Treasury yields in effect at the time of grant. The estimated weighted-average fair values of and related assumptions for options granted were as follows:

	Six Months Ended June 30,
	2007			2006
Weighted-average fair value of options granted	$	4.90		$	3.82
Assumptions:
Dividend yield	3.80		%	4.77		%
Expected volatility	22.75		%	25.49		%
Risk-free interest rate	4.96		%	5.14		%
Expected life of option (years)	5.33			5.00

4.Stock-Based Compensation (Continued)

A summary of the Company’s stock option activity and related information follows:

	Options		Weighted- Average Exercise Price			Weighted- Average Remaining Contractual Term (years)		Aggregate Intrinsic Value
								(In thousands)
Outstanding at December 31, 2006	3,451,077			$	17.96
Granted	221,267			25.82
Exercised	(660,738	)		15.30
Forfeited	(11,555	)		22.07
Outstanding at June 30, 2007	3,000,051			$	19.11		5.4		$	18,605
Outstanding—vested or expected to vest at June 30, 2007	2,971,521			$	19.07		5.3		$	18,557
Exercisable at June 30, 2007	2,313,244			$	17.89		5.1		$	17,168

The total intrinsic value of options exercised during the three months ended June 30, 2007 and 2006 was $3,285,000 and $445,000, respectively, and during the six months ended June 30, 2007 and 2006 was $6,489,000 and $1,288,000, respectively. As of June 30, 2007, there was $3,046,000 of total unrecognized compensation cost related to non-vested stock option awards granted under the Company’s equity incentive plan. That cost is expected to be recognized over a weighted-average period of 1.8 years.

During 2003, the Company began granting shares of restricted stock to certain of its employees and directors. Restricted stock awards granted to employees vest at the end of a three- or four-year period, whereas restricted stock awards granted to directors vest at the end of a six-month period. The fair value of restricted stock is determined based on the closing price of the Company’s common stock on the grant date. The Company generally recognizes compensation expense associated with restricted stock awards ratably over their vesting periods. As PCA’s Board of Directors has the ability to accelerate vesting of restricted stock upon an employee’s retirement, the Company accelerates the recognition of compensation expense for certain employees approaching normal retirement age. A summary of the Company’s restricted stock activity follows:

	2007						2006
(dollars in thousands)	Shares		Fair Market Value at Date of Grant				Shares		Fair Market Value at Date of Grant
Restricted stock at January 1	610,380			$	12,964		387,030			$	8,256

4.Stock-Based Compensation (Continued)

As of June 30, 2007, there was $11,293,000 of total unrecognized compensation costs related to the above restricted stock awards. The Company expects to recognize the cost of these stock awards over a weighted-average period of 2.7 years.

5.Inventories

The components of inventories are as follows:

	June 30, 2007				December 31, 2006
(In thousands)	(unaudited)
Raw materials		$	81,798			$	87,243
Work in process		7,218				5,021

Supplies and materials		84,962				83,431
Inventories at FIFO or average cost		241,579				239,328
Excess of FIFO or average over LIFO cost		(42,849		)		(43,382		)
Inventories, net		$	198,730			$	195,946

An actual valuation of inventory under the LIFO method is made only at the end of each year based on the inventory levels and costs at that time. Accordingly, interim LIFO calculations must necessarily be based on management’s estimates of expected year-end inventory levels and costs. Because these are subject to many factors beyond management’s control, interim results are subject to the final year-end LIFO inventory valuation.

8.Restructuring Charges

In August 2005, the Company announced that it would close a corrugated products plant by December 31, 2005. The charges related to this plant closing were recorded in accordance with SFAS No. 146, “Accounting for Costs Associated with Exit or Disposal Activities,” which requires that a liability for costs associated with an exit or disposal activity be recognized when the liability is incurred. In connection with the shutdown of the corrugated products plant, the Company recorded pre-tax restructuring charges of $1.7 million during 2005 and $325,000 during 2006. On November 3, 2006, PCA sold the building for cash proceeds of $378,000 and recorded a pre-tax gain of $378,000.

In August 2006, the Company announced that it would close a corrugated products plant by the end of the third quarter of 2006. In connection with the closing of this plant, the Company sold the equipment and the building for cash proceeds of $1.6 million and recorded a pre-tax loss of $319,000. The Company also recorded severance of $454,000 and wrote off $174,000 of assets, primarily intangible assets.

The following table presents an analysis of the 2007 activity related to the prior years’ restructurings:

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

Overview

Packaging Corporation of America, or PCA, is the sixth largest producer of containerboard and corrugated products in the United States, based on production capacity. Approximately 80% of the containerboard tons produced at our mills are consumed in our corrugated products manufacturing plants. The remaining 20% is sold to domestic customers or the export market. Besides containerboard, we produce a wide variety of products ranging from basic corrugated shipping containers to specialized packaging such as wax-coated boxes for the agriculture industry. We also have multi-color printing capabilities to make high-impact graphics boxes and displays that offer our customers more attractive packaging. Our operating facilities and customers are located primarily in the United States.

In analyzing the operating performance of the company, we focus on the following factors that affect our business and are important to consider when reviewing our financial and operating results:

·corrugated products demand;

·corrugated products and containerboard pricing;

·containerboard inventories; and

·cost trends and volatility for our major costs, including wood and recycled fiber, purchased energy, labor and fringe benefits, and transportation costs.

The market for containerboard is generally subject to changes in the U.S. economy. Historically, supply and demand, as well as industry-wide inventory levels, has influenced prices of containerboard. In addition to U.S. shipments, approximately 10% of domestically produced containerboard has been exported for use in other countries.

Industry supply and demand trends remained in balance during the second quarter of 2007. Although industry shipments of corrugated products decreased 1.6% for the three months ended June 30, 2007 compared to the same period in 2006, industry containerboard inventory levels remained at historically low levels. Industry inventories of containerboard at the end of the second quarter were at the lowest June ending level in the past 30 years on a weeks of supply basis. As reported by industry publications, linerboard prices for the second quarter of 2007 were the same as last year’s second quarter and have remained unchanged since the April 2006 $50 per ton price increase.

The cost to manufacture containerboard is dependent, in large part, on the costs of wood fiber, recycled fiber, purchased fuels, electricity and labor and fringe benefits. While energy and other costs are significant in the manufacture of corrugated products, labor and fringe benefits make up the largest component of corrugated products’ manufactured costs, excluding the cost of containerboard.

Industry publications reported that recycled fiber prices increased significantly during the first quarter of 2007 and then decreased somewhat during the second quarter. Average prices, for the first and second quarter, were essentially flat. Wood costs came down from first quarter levels as logging conditions improved due to dryer weather during the second quarter. Purchased fuel costs decreased slightly from the levels in the second quarter of 2006. Transportation and purchased electricity costs were higher in the second quarter of 2007 compared to the second quarter of 2006, but were comparable to the rates in the first quarter 2007.

For the quarter ended June 30, 2007, PCA reported significantly higher earnings than the prior year. This was primarily driven by increased product pricing for both containerboard and corrugated products, reflecting the full realization of  2006 price increases, and an improvement in product and customer sales mix. Although corrugated product sales volumes decreased 0.3%, compared to last year’s second quarter,

17

the decrease was more than offset by outside containerboard sales, which increased 23,000 tons for the same time period. Partially offsetting the earnings improvement were higher labor and fringe benefits costs, including medical and incentive compensation costs, and increased recycled  fiber costs.

We expect our earnings from operations for the third quarter to be slightly higher than our earnings from operations for the second quarter. Corrugated products volume is expected to remain steady and we have no planned mill maintenance outages. Higher costs in the areas of recycled fiber and transportation are expected to be partially offset by seasonally lower energy costs.

Results of Operations

Three Months Ended June 30, 2007 Compared to Three Months Ended June 30, 2006

The historical results of operations of PCA for the three months ended June 30, 2007 and 2006 are set forth below:

	Three Months Ended June 30,
(In thousands)	2007			2006			Change
Net sales	$	585,628		$	551,095		$	34,533
Income from operations	$	80,224		$	57,551		$	22,673
Interest expense, net	(6,928		)	(8,210		)	1,282
Income before taxes	73,296			49,341			23,955
Provision for income taxes	(27,069		)	(17,260		)	(9,809		)
Net income	$	46,227		$	32,081		$	14,146

Net Sales

Net sales increased by $34.5 million, or 6.3%, for the three months ended June 30, 2007 from the comparable period in 2006. The increase was primarily the result of increased sales prices of corrugated products and containerboard to third parties and increased sales volume of containerboard to outside third parties.

Corrugated products volume sold for the three months ended June 30, 2007 decreased 0.3% to 8.00 billion square feet (“bsf”) compared to  8.03 bsf in the second quarter of 2006. Containerboard volume sold to external domestic and export customers was up 10.6% and 37.6%, respectively, for the three months ended June 30, 2007 from the three months ended June 30, 2006. Containerboard mill production for the three months ended June 30, 2007 was 615,000 tons compared to 592,000 tons in the same period in 2006.

Income From Operations

Income from operations increased by $22.7 million, or 39.4%, for the three months ended June 30, 2007 compared to the three months ended June 30, 2006. The increase in income from operations was primarily attributable to increased sales prices, sales volumes and improved product and customer mix ($26.9 million) and lower mill maintenance outage costs ($3.8 million), partially offset by increased costs of recycled fiber ($3.9 million), fringe benefits ($3.1 million) which include medical, pension and incentive compensation costs, and salaries ($2.4 million) which includes expenses for share-based compensation.

Gross profit increased $28.2 million, or 25.2%, for the three months ended June 30, 2007 from the comparable period in 2006. Gross profit as a percentage of net sales increased from 20.3% of net sales in the three months ended June 30, 2006 to 23.9% of net sales in the current quarter due primarily to the improved sales prices, volumes and mix described previously.

18

Selling and administrative expenses increased $3.3 million, or 8.4%, for the three months ended June 30, 2007 compared to the same period in 2006. The increase was primarily the result of higher expenses related to salaries including merit increases, incentive compensation, new hires, and share-based compensation expense ($2.2 million), related fringe benefits ($0.4 million) and warehousing costs ($0.3 million).

Corporate overhead increased $2.4 million, or 19.2%, for the three months ended June 30, 2007 compared to the same period in 2006, primarily due to increases in salary and related fringe benefit costs which include expenses recorded for merit increases, share-based compensation and incentive compensation ($1.0 million), information technology costs ($0.7 million), professional fees for investor relations, audit and tax matters ($0.5 million), and travel and entertainment costs ($0.2 million).

Other expense for the three months ended June 30, 2007 decreased $0.1 million, or 5.4%, compared to the three months ended June 30, 2006. The decrease was related to individually insignificant items.

Interest Expense, Net and Income Taxes

Net interest expense decreased $1.3 million, or 15.6%, for the three months ended June 30, 2007 from the three months ended June 30, 2006, primarily as a result of increased income earned on PCA’s cash equivalents due to higher cash balances.

PCA’s effective tax rate was 36.9% for the three months ended June 30, 2007 and 35.0% for the comparable period in 2006. The effective tax rate varies from the U.S. federal statutory tax rate of 35% principally due to the impact of state and local income taxes offset by the domestic manufacturers’ deduction.

Six Months Ended June 30, 2007 Compared to Six Months Ended June 30, 2006

The historical results of operations of PCA for the six months ended June 30, 2007 and 2006, are set forth below:

	For the Six Months  Ended June 30,
(In thousands)	2007			2006			Change
Net sales	$	1,144,787		$	1,058,951		$	85,836
Income from operations	$	136,920		$	83,067		$	53,853
Interest expense, net	(14,060		)	(16,260		)	2,200
Income before taxes	122,860			66,807			56,053
Provision for income taxes	(45,442		)	(23,791		)	(21,651		)
Net income	$	77,418		$	43,016		$	34,402

Net Sales

Net sales increased by $85.8 million, or 8.1%, for the six months ended June 30, 2007 from the comparable period in 2006. The increase was primarily the result of increased sales prices of corrugated products and containerboard and increased sales volume of containerboard to outside third parties.

Total corrugated products volume sold for the six months ended June 30, 2007 decreased 1.5% to 15.71 bsf compared to 15.95 bsf in the first half of 2006. Containerboard volume to external domestic and export customers increased 9.4% and 58.7%, respectively, for the six months ended June 30, 2007 from the six months ended June 30, 2006. Containerboard mill production for the six months ended June 30, 2007 was 1,200,000 tons compared to 1,170,000 tons in the same period in 2006.

19

Income From Operations

Income from operations increased by $53.9 million, or 64.8%, for the six months ended June 30, 2007 compared to the six months ended June 30, 2006. The increase in income from operations was primarily attributable to higher sales prices and improved product mix ($74.9 million) which was partially offset by increased recycled fiber costs ($8.3 million), fringe benefits, which include medical and pension costs and incentive compensation accruals ($6.7 million), and salary expenses which includes share-based compensation ($4.6 million).

Gross profit increased $64.6 million, or 34.3%, for the six months ended June 30, 2007 from the comparable period in 2006. Gross profit as a percentage of net sales increased from 17.8% of net sales in the first six months of 2006 to 22.1% of net sales in the first six months of 2007 due primarily to the increased prices and improved mix described previously.

Selling and administrative expenses increased $7.6 million, or 9.8%, for the six months ended June 30, 2007 compared to the same period in 2006. The increase was primarily the result of expenses related to salaries including merit increases, incentive compensation, new hires, and share-based compensation expense ($4.5 million), related fringe benefits ($0.8 million), travel, meeting and entertainment expenses ($1.0  million), and warehousing costs ($0.5 million) due to increased customer requirements.

Corporate overhead increased $4.1 million, or 17.4%, for the six months ended June 30, 2007 compared to the same period in 2006, primarily due to increases in salary and related fringe benefit costs which include expenses recorded for merit increases, share-based compensation and incentive compensation ($2.5 million), information technology costs ($1.0 million), and professional fees paid for audit, investor relations, human resource and tax matters ($0.6 million).

Other expense for the six months ended June 30, 2007 decreased $0.9 million, or 19.4%, compared to the six months ended June 30, 2006. The decrease was related to individually insignificant items.

Interest Expense, Net and Income Taxes

Net interest expense decreased $2.2 million, or 13.5%, for the six months ended June 30, 2007 from the six months ended June 30, 2006, primarily as a result of increased income earned on PCA’s cash equivalents due to higher cash balances.

PCA’s effective tax rate was 37.0% for the six months ended June 30, 2007 and 35.6% for the comparable period in 2006. The effective tax rate varies from the U.S. federal statutory tax rate of 35% principally due to the impact of state and local income taxes offset by the domestic manufacturers’ deduction.

Liquidity and Capital Resources

The following table presents a summary of our cash flows for the periods presented:

	Six Months Ended June 30,
(In thousands)	2007			2006			Change
Net cash provided by (used for):
Operating activities	$	129,653		$	79,867		$	49,786
Investing activities	(43,247		)	(47,857		)	4,610
Financing activities	(40,168		)	(50,601		)	10,433
Net increase (decrease) in cash and cash equivalents	$	46,238		$	(18,591	)	$	64,829

20

Operating Activities

Net cash provided by operating activities for the six months ended June 30, 2007 was $129.7 million, a increase of $49.8 million, or 62.3%, from the comparable period in 2006. The increase in net cash provided by operating activities was primarily the result of higher net income in 2007 as previously described and lower requirements for operating assets and liabilities of $21.0 million for the six months ended June 30, 2007 compared to the same period in 2006. The lower requirements for operating assets and liabilities were driven by favorable year over year changes in accounts receivable ($22.7 million) and accounts payable ($10.3 million), partially offset by unfavorable year over year changes in accrued liabilities ($9.6 million).

Investing Activities

Net cash used for investing activities for the six months ended June 30, 2007 decreased $4.6 million, or 9.6%, to $43.2 million, compared to the six months ended June 30, 2006. The decrease was primarily related to the cost of acquisitions in 2006 of $4.2 million and lower additions to other long term assets of $1.9 million, partially offset by an increase in additions to property, plant and equipment of $1.4 million during the six months ended June 30, 2007 compared to the same period in 2006.

Financing Activities

Net cash used for financing activities totaled $40.2 million for the six months ended June 30, 2007, a decrease of $10.4 million, or 20.6%, from the comparable period in 2006. The decrease was primarily attributable to $8.3 million in additional proceeds from the issuance of common stock upon exercise of stock options and an increase in excess tax benefits related to the stock option exercises of $1.6 million during the six months ended June 30, 2007 compared to the same period in 2006.

PCA’s primary sources of liquidity are net cash provided by operating activities, borrowings under PCA’s revolving credit facility, and additional borrowings under PCA’s receivables credit facility. As of June 30, 2007, PCA had $121.6 million in unused borrowing capacity under its existing credit agreements, net of the impact on this borrowing capacity of $19.4 million of outstanding letters of credit. Currently, PCA’s primary uses of cash are for capital expenditures, debt service and declared common stock dividends, which it expects to be able to fund from these sources.

The following table provides the outstanding balances and the weighted average interest rates as of June 30, 2007 for PCA’s outstanding term loan, the revolving credit facility, the receivables credit facility, and the five- and ten-year senior notes:

Borrowing Arrangement	Principal Balance at June 30, 2007			Weighted Average Interest Rate			Projected Annual Cash Interest Payments
(In thousands)
Senior Credit Facility:
Term loan		$	30,000		6.63	%		$	1,988
Revolving credit facilty		—			N/A			N/A
Receivables Credit Facility		109,000			5.66			6,170
43¤8% Five-Year Notes (due August 1, 2008)		150,000			4.38			6,570

The above table excludes unamortized debt discount of $2.2 million at June 30, 2007. It also excludes from the projected annual cash interest payments, the non-cash income from the annual amortization of the $27.0 million received in July 2003 from the settlement of the treasury locks related to the five- and

21

ten-year notes. The amortization is being recognized over the terms of the five- and ten-year notes and is included in interest expense, net.

The revolving credit facility is available to fund PCA’s working capital requirements, capital expenditures and other general corporate purposes. The term loan must be repaid in annual installments in July 2007 through 2008. The revolving credit facility will terminate in July 2008. The receivables credit facility will termininate in October 2007. The Company plans to renew this facility at that time.

The instruments governing PCA’s indebtedness contain financial and other covenants that limit, among other things, the ability of PCA and its subsidiaries to:

·enter into sale and leaseback transactions,

·incur liens,

·enter into certain transactions with affiliates, or

·merge or consolidate with any other person or sell or otherwise dispose of all or substantially all of the assets of PCA.

These limitations could limit our corporate and operating activities.

In addition, we must maintain minimum net worth, maximum leverage and minimum coverage ratios under the senior credit facility. A failure to comply with the restrictions contained in our senior credit facility could lead to an event of default, which could result in an acceleration of such indebtedness. Such an acceleration would also constitute an event of default under the notes indentures and the receivables credit facility. As of June 30, 2007, PCA was in compliance with these covenants.

PCA currently expects to incur capital expenditures of $110.0 million to $120.0 million in 2007. These expenditures will be used primarily for maintenance capital, cost reduction, business growth and environmental compliance. As of June 30, 2007, PCA had spent $41.9 million for capital expenditures and had committed to spend an additional $61.0 million in the remainder of 2007 and beyond.

PCA believes that its net cash generated from operating activities, available cash reserves and, as required, borrowings under its committed credit facilities will be adequate to meet its current and future liquidity and capital requirements, including payments of any declared common stock dividends. As its debt or credit facilities become due, PCA will need to repay, extend or replace such facilities, which will be subject to future economic conditions and financial, business and other factors, many of which are beyond PCA’s control.

Market Risk and Risk Management Policies

PCA is exposed to the impact of interest rate changes and changes in the market value of its financial instruments. PCA periodically enters into derivatives in order to minimize these risks, but not for trading purposes. As of June 30, 2007, PCA was not a party to any derivative instruments.

As the interest rates on approximately 80% of PCA’s debt are fixed, a one percent increase in interest rates related to variable rate debt would have resulted in an increase in interest expense and a corresponding decrease in income before taxes of $1.4 million annually. In the event of a change in interest rates, management could take actions to mitigate its exposure to the change. However, due to the uncertainty of the specific actions that would be taken and their possible effects, the sensitivity analysis assumes no changes in PCA’s financial structure.

Environmental Matters

We are subject to, and must comply with, a variety of federal, state and local environmental laws, particularly those relating to air and water quality, waste disposal and the cleanup of contaminated soil and groundwater. The most significant of these laws affecting us are:

·Resource Conservation and Recovery Act (RCRA);

·Clean Water Act (CWA);

·Clean Air Act (CAA);

·The Emergency Planning and Community Right-to-Know-Act (EPCRA);

·Toxic Substance Control Act (TSCA); and

·Safe Drinking Water Act (SDWA).

We believe that we are currently in material compliance with these and all applicable environmental rules and regulations. Because environmental regulations are constantly evolving, we have incurred, and will continue to incur, costs to maintain compliance with these and other environmental laws. In particular, the United States Environmental Protection Agency Cluster Rules which govern pulp and paper mill operations, including those at the Counce, Filer City, Valdosta and Tomahawk mills will affect our allowable discharges of air and water pollutants. We completed all of our projects related to the Cluster Rules at our four mills during 2006.

Impact of Inflation

PCA does not believe that inflation has had a material impact on its financial position or results of operations during the three- and six-month periods ending June 30, 2007 and 2006.

Off-Balance Sheet Arrangements

PCA does not have any off-balance sheet arrangements as of June 30, 2007 that would require disclosure under SEC FR-67, “Disclosure in Management’s Discussion and Analysis About Off-Balance Sheet Arrangement and Aggregate Contractual Obligations.”

Critical Accounting Policies and Estimates

Management’s discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosures of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates, including those related to bad debts, inventories, intangible assets, pensions and other postretirement benefits, income taxes, and contingencies and litigation. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

PCA has included in its Annual Report on Form 10-K for the year ended December 31, 2006, a discussion of its critical accounting policies which we believe affect our more significant judgments and estimates used in the preparation of our consolidated financial statements. PCA adopted FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes,” on January 1, 2007.

23

Income Taxes

PCA’s annual tax rate is determined based on income, statutory tax rates and the tax impacts of items treated differently for tax purposes than for financial reporting purposes. Tax law requires some items to be included in the tax return at different times than the items reflected in the financial statements. As a result, the annual tax rate in the financial statements is different than the rate reported on PCA’s tax return. Some of these differences are permanent, such as expenses that are not deductible in the tax return, and some differences are temporary, reversing over time, such as depreciation expense. These temporary differences create deferred tax assets and liabilities.

Inherent in determining the annual tax rate are judgments regarding business plans, planning opportunities and expectations about future outcomes. Significant management judgments are required for the following items:

·Management reviews PCA’s deferred tax assets for realizability. Valuation allowances are established when management believes that it is more likely than not that some portion of the deferred tax assets will not be realized. Changes in valuation allowances from period to period are included in the tax provision.

·PCA establishes accruals for uncertain tax contingencies when, despite the belief that PCA’s tax return positions are fully supported, PCA believes that uncertain positions may be challenged. The tax contingency accruals are adjusted in light of changing facts and circumstances, such as the progress of tax audits, the expiration of the statute of limitations for the relevant taxing authority to examine a tax return, case law and emerging legislation. While it is difficult to predict the final outcome or timing of resolution for any particular tax matter, PCA believes that the accruals reflect the likely outcome of known tax contingencies in accordance with FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes.”

Forward-Looking Statements

Some of the statements in this Quarterly Report on Form 10-Q, and in particular, statements found in Management’s Discussion and Analysis of Financial Condition and Results of Operations, that are not historical in nature are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These statements are often identified by the words “will,” “should,” “anticipate,” “believe,” “expect,” “intend,” “estimate,” “hope,” or similar expressions. These statements reflect management’s current views with respect to future events and are subject to risks and uncertainties. There are important factors that could cause actual results to differ materially from those in forward-looking statements, many of which are beyond our control. These factors, risks and uncertainties include the following:

·the impact of general economic conditions;

·containerboard and corrugated products general industry conditions, including competition, product demand and product pricing;

·fluctuations in wood fiber and recycled fiber costs;

·fluctuations in purchased energy costs; and

·legislative or regulatory requirements, particularly concerning environmental matters.

Our actual results, performance or achievement could differ materially from those expressed in, or implied by, these forward-looking statements, and accordingly, we can give no assurances that any of the events anticipated by the forward-looking statements will transpire or occur, or if any of them do so, what impact they will have on our results of operations or financial condition. In view of these uncertainties, investors are cautioned not to place undue reliance on these forward-looking statements. We have no

24

obligation to publicly revise any forward-looking statements that have been made to reflect the occurrence of events after the date hereof. For a discussion of other factors, risks and uncertainties that may affect our business, see Item 1A. Risk Factors included in Annual Report on Form 10-K for the year ended December 31, 2006.

Item 3.        Quantitative and Qualitative Disclosures About Market Risk.

For a discussion of market risks related to PCA, see Part I, Item 2, “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Market Risk and Risk Management Policies” in this Quarterly Report on Form 10-Q.

Item 4.Controls and Procedures.

PCA maintains disclosure controls and procedures (as defined in Rule 13a-15(e) of the Securities Exchange Act of 1934) that are designed to provide reasonable assurance that information required to be disclosed in PCA’s filings under the Securities Exchange Act is recorded, processed, summarized and reported within the periods specified in the rules and forms of the SEC and that such information is accumulated and communicated to PCA’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Prior to filing this report, PCA completed an evaluation under the supervision and with the participation of PCA’s management, including PCA’s Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of PCA’s disclosure controls and procedures as of June 30, 2007. The evaluation of PCA’s disclosure controls and procedures included a review of the controls’ objectives and design, PCA’s implementation of the controls and the effect of the controls on the information generated for use in this report. Based on this evaluation, PCA’s Chief Executive Officer and Chief Financial Officer concluded that PCA’s disclosure controls and procedures were effective at the reasonable assurance level as of June 30, 2007.

During the quarter ended June 30, 2007, there were no changes in internal controls over financial reporting that have materially affected, or are reasonably likely to materially affect, PCA’s internal control over financial reporting.
