Overview



PCA is the third largest producer of containerboard products and a leading
producer of uncoated freesheet paper in North America. We operate eight mills
and 90 corrugated products manufacturing plants. Our containerboard mills
produce linerboard and corrugating medium, which are papers primarily used in
the production of corrugated products. Our corrugated products manufacturing
plants produce a wide variety of corrugated packaging products, including
conventional shipping containers used to protect and transport manufactured
goods, multi-color boxes and displays with strong visual appeal that help to
merchandise the packaged product in retail locations, and honeycomb protective
packaging. In addition, we are a large producer of packaging for meat, fresh
fruit and vegetables, processed food, beverages, and other industrial and
consumer products. We also manufacture and sell uncoated freesheet papers,
including both commodity and specialty papers, which may have custom or
specialized features such as colors, coatings, high brightness, and recycled
content. We are headquartered in Lake Forest, Illinois and operate primarily in
the United States.

This Item 2 is intended to supplement, and should be read in conjunction with, "Management's Discussion and Analysis of Financial Condition and Results of Operations" included in our 2020 Annual Report on Form 10-K.

Executive Summary



First quarter net sales were $1.81 billion in 2021 and $1.71 billion in 2020. We
reported $167 million of net income, or $1.75 per diluted share, during the
first quarter of 2021, compared to $142 million, or $1.49 per diluted share,
during the same period in 2020. Net income included $2 million of expense for
special items in the first quarter of 2021, compared to $1 million of expense
for special items in 2020 (discussed below). Excluding special items, net income
was $169 million, or $1.77 per diluted share, during the first quarter of 2021,
compared to $143 million, or $1.50 per diluted share, in the first quarter of
2020. The increase in net income was driven primarily by higher volume and
prices and mix in our Packaging segment, and lower annual outage expenses. These
items were partially offset by lower volume and prices and mix in our Paper
segment, higher operating costs, higher freight and logistics expenses, higher
converting costs, and other expenses. For additional detail on special items
included in reported GAAP results, as well as segment income (loss) excluding
special items, earnings before non-operating pension income (expense), interest,
income taxes, and depreciation, amortization, and depletion (EBITDA), and EBITDA
excluding special items, see "Item 2. Reconciliations of Non-GAAP Financial
Measures to Reported Amounts."

Packaging segment income from operations was $258 million in the first quarter
of 2021, compared to $200 million in the first quarter of 2020. Packaging
segment EBITDA excluding special items was $352 million in the first quarter of
2021 compared to $290 million in the first quarter of 2020. The increase in
EBITDA excluding special items was due primarily to higher sales and production
volumes, higher prices and mix, and lower annual outage costs, partially offset
by higher operating and converting costs, higher freight and logistic expenses,
and other costs. Demand for our Packaging products remained strong throughout
the first quarter, and we increased our containerboard production over the prior
year period by producing linerboard during the entire quarter on the No. 3
machine at our Jackson, Alabama mill. During the fourth quarter of 2020, in
order to meet strong packaging demand and maintain appropriate inventory levels,
we temporarily began producing linerboard on the machine. In the first quarter
of 2021, we announced the discontinuation of production of uncoated freesheet
paper grades on the machine and the permanent conversion of the machine to
produce linerboard in a phased approach over the next three years. Before
October 2020, operating results for the Jackson mill were included in the Paper
segment. Beginning in October 2020, operating results for the Jackson mill are
included in both the Packaging and Paper segments.

Paper segment income from operations was $9 million in the first quarter of
2021, compared to income of $33 million in the first quarter of 2020. Paper
segment EBITDA excluding special items was $16 million in the first quarter of
2021, compared to $42 million in the first quarter of 2020. The decrease in
EBITDA excluding special items was due to lower sales and production volumes,
lower prices and mix, and higher freight and logistic expenses, partially offset
by lower operating costs and lower annual outage expense. Sales were 24% lower
than last year as demand has continued to be negatively affected by the COVID-19
pandemic and related closures of offices and schools.

Demand for our corrugated products remains strong into the second quarter, and
we continue to implement price increases that we previously announced to our
packaging customers late in 2020 and earlier in 2021. We expect paper volumes to
remain consistent with the first quarter and higher paper pricing as we realize
price increases recently notified to our customers. We expect higher expenses in
the second quarter than the first quarter relating to maintenance outages at our
mills and continued inflation in freight and most of our other operating and
converting costs.

includes $2.1 million and $0.4 million of charges consisting of closure


      costs related to corrugated products facilities.



(b) For the three months ended March 31, 2021, includes $1.1 million of charges

related to the announced discontinuation of production of uncoated

freesheet paper grades on the No. 3 machine at the Jackson, Alabama mill in

the first quarter of 2021 associated with the permanent conversion of the


      machine to produce linerboard.



(c) The three months ended March 31, 2020 include $0.8 million of incremental,


      out-of-pocket costs related to COVID-19, including supplies, cleaning and
      sick pay. Beginning in July 2020, all corresponding COVID-19 related
      expenses were included in normalized costs.




Included in this Item 2 are various non-GAAP financial measures, including
diluted EPS excluding special items, segment income excluding special items and
EBITDA excluding special items. Management excludes special items as it believes
these items are not necessarily reflective of the ongoing results of operations
of our business. We present these measures because they provide a means to
evaluate the performance of our segments and our Company on an ongoing basis
using the same measures that are used by our management, because these measures
assist in providing a meaningful comparison between periods presented and
because these measures are frequently used by investors and other interested
parties in the evaluation of companies and the performance of their segments. A
reconciliation of diluted EPS to diluted EPS excluding special items is included
above and the reconciliations of other non-GAAP measures used in this
Management's Discussion and Analysis of Financial Condition and Results of
Operations, to the most comparable measure reported in accordance with GAAP, are
included in Item 2 under "Reconciliations of Non-GAAP Financial Measures to
Reported Amounts." Any analysis of non-GAAP financial measures should be done in
conjunction with results presented in accordance with GAAP. The non-GAAP
measures are not intended to be substitutes for GAAP financial measures and
should not be used as such.

Industry and Business Conditions



Trade publications reported North American industry-wide corrugated products
shipments per work day were up 5.5% during the first quarter of 2021 compared to
the same quarter of 2020. Reported industry containerboard production increased
2.1% compared to the first quarter of 2020. Reported industry containerboard
inventories at the end of the first quarter of 2021 were approximately 2.3
million tons, down 9.9% compared to the same period in 2020. Reported

Net Sales

Net sales increased $98 million, or 5.7%, to $1,807 million during the three
months ended March 31, 2021, compared to $1,709 million during the same period
in 2020.

Packaging. Net sales increased $156 million, or 10.6%, to $1,624 million,
compared to $1,468 million in the first quarter of 2020 due to higher
containerboard and corrugated products volume ($106 million) and higher prices
and mix ($50 million). In the first quarter of 2021, our domestic containerboard
prices were 3.4% higher, while export prices were 16.2% higher, than the same
period in 2020. In the first quarter of 2021, export and domestic containerboard
outside shipments increased 12.9% compared to the first quarter of 2020. Our
total corrugated products shipments were up 6.6% with one less workday, and up
8.3% per day compared to the same period in 2020, driven by strong demand.

Paper. Net sales during the three months ended March 31, 2021 decreased $53
million, or 24.2%, to $165 million, compared to $217 million in the first
quarter of 2020, due to decreased volume ($48 million) and lower prices and mix
($5 million), as demand has been harmed by the COVID-19 pandemic. In the fourth
quarter of 2020, the Jackson mill No. 3 machine began producing linerboard to
balance supply and demand.

Gross Profit

Gross profit increased $39 million during the three months ended March 31, 2021,
compared to the same period in 2020. The increase was driven primarily by higher
volume and prices and mix in our Packaging segment, and lower annual outage
expenses. These items were partially offset by lower volume and prices and mix
in our Paper segment, higher operating costs, higher freight and logistics
expenses, higher converting costs, and other expenses. In the three months ended
March 31, 2021, gross profit included $0.5 million of special items for charges
related to the Jackson mill conversion. In the three months ended March 31,
2020, gross profit included $1 million of special items for incremental,
out-of-pocket costs related to COVID-19.

--------------------------------------------------------------------------------

Selling, General, and Administrative Expenses



Selling, general, and administrative expenses ("SG&A") decreased $1 million
during the three months ended March 31, 2021, compared to the same period in
2020. The decrease was primarily due to lower travel and entertainment expenses
partially offset by higher employee salaries and fringes and incentives.

Other Expense, Net

Other expense, net, for the three months ended March 31, 2021 and 2020 are set forth below (dollars in millions):





                                       Three Months Ended

We discuss these items in more detail in Note 5, Other Expense, Net, of the Condensed Notes to Unaudited Quarterly Consolidated Financial Statements in "Part I, Item 1. Financial Statements" of this Form 10-Q.

Income from Operations



Income from operations increased $29 million, or 13.9%, during the three months
ended March 31, 2021, compared to the same period in 2020. The first quarter of
2021 included $3 million of special items expense related to corrugated facility
closure costs and the Jackson mill conversion from uncoated freesheet paper to
linerboard, compared to $1 million of special items expense for incremental,
out-of-pocket costs related to COVID-19 in the first quarter of 2020.

Packaging. Packaging segment income from operations increased $58 million to
$258 million, compared to $200 million during the three months ended March 31,
2020. The increase related primarily to higher sales and production volumes ($57
million), higher containerboard and corrugated products prices and mix ($42
million) and lower annual outage expense ($10 million), partially offset by
higher operating and converting costs ($36 million), higher freight expenses ($9
million), higher depreciation expense ($3 million), and other costs. Special
items during the first quarter of 2021 included $2 million of expenses related
to corrugated facility closure costs, compared to $1 million of special items
expense for incremental, out-of-pocket costs related to COVID-19 in the first
quarter of 2020.

Paper. Paper segment income from operations decreased $24 million to $9 million,
compared to income of $33 million during the three months ended March 31, 2020.
The decrease primarily related to lower sales and production volumes ($36
million), lower prices and mix ($4 million), and higher freight expenses ($7
million), partially offset by lower operating costs ($19 million), lower annual
outage expense ($5 million), and other costs. Special items during the first
quarter of 2021 included $1 million of expenses related to the Jackson mill
conversion from uncoated freesheet paper to linerboard, compared to no special
items in the first quarter of 2020.

Non-Operating Pension Income, Interest Expense, Net and Income Taxes



Non-operating pension income increased $4 million during the three months ended
March 31, 2021, compared to the same period in 2020. The increase in
non-operating pension income was primarily related to the favorable 2020 asset
performance.



Interest expense, net increased $4 million during the three months ended March
31, 2021, compared to the same period in 2020. The increase in interest expense,
net was primarily related to lower interest income due to lower rates on
invested cash balances in the first quarter of 2021, and higher earnings on
deferred compensation balances in the first quarter of 2021.



During the three months ended March 31, 2021, we recorded $53 million of income
tax expense, compared to $48 million of expense during the three months ended
March 31, 2020. The effective tax rate for the three months ended March 31, 2021
and 2020 was 24.2% and 25.5%, respectively. The decrease in our effective tax
rate was primarily due to a favorable state law change during the three months
ended March 31, 2021 with no corresponding favorable state law change during the
three months ended March 31, 2020.

Liquidity and Capital Resources

Sources and Uses of Cash



Our primary sources of liquidity are net cash provided by operating activities,
cash on hand, and available borrowing capacity under our revolving credit
facility. At March 31, 2021, we had $983 million of cash and cash equivalents,
$150 million of marketable debt securities, and $325 million of unused borrowing
capacity under the revolving credit facility, net of letters of
credit. Currently, our primary uses of cash are for operations, capital
expenditures, common stock dividends, debt service, acquisitions, and
repurchases of common stock. We believe that net cash generated from operating
activities, cash on hand, available borrowings under our revolving credit
facility, and available capital through access to capital markets will be
adequate to meet our liquidity and capital requirements, including payments of
any declared common stock dividends, for the foreseeable future. As our debt or
credit facilities become due, we will need to repay, refinance, extend, or
replace such debt or credit facilities. Our ability to do so will be subject to
future economic conditions and financial, business, and other factors, many of
which are beyond our control.



Below is a summary table of our cash flows, followed by a discussion of our sources and uses of cash through operating activities, investing activities, and financing activities (dollars in millions):

(20.1 ) Net increase in cash and cash equivalents $ 8.8 $ 84.5 $ (75.7 )




Operating Activities

Our operating cash flow is primarily driven by our earnings and changes in
operating assets and liabilities, such as accounts receivable, inventories,
accounts payable and other accrued liabilities, as well as factors described
below. Cash requirements for operating activities are subject to PCA's operating
needs and the timing of collection of receivables and payments of payables and
expenses.

During the three months ended March 31, 2021, net cash provided by operating
activities was $192 million, compared to $237 million in the same period in
2020, a decrease of $45 million. Cash from operations excluding changes in cash
used for operating assets and liabilities increased $26 million primarily due to
higher income from operations as discussed above. Cash decreased by $71 million
due to changes in operating assets and liabilities, primarily due to the
following:

       a) a larger increase in accounts receivable due to sales volumes in the
          first quarter of 2021 in both the Packaging and Paper segments as well
          as timing of collection of receivables in the Paper segment, and

b) a decrease in accounts payable in 2021 compared to 2020 primarily due to

the timing of payments as well as lower expenditures in connection with

annual maintenance outages performed in the first quarter of 2021


          compared to 2020.


Investing Activities

We used $88 million for investing activities during the three months ended March
31, 2021 compared to $77 million during the same period in 2020. We spent $85
million for internal capital investments during the three months ended March 31,
2021, compared to $71 million during the same period in 2020.



We expect capital investments in 2021 to be between $650 million and $675
million, including capital spending related to the conversion of the No. 3 paper
machine to containerboard at our Jackson mill. These expenditures could increase
or decrease as a result of a number of factors, including our financial results,
strategic opportunities, future economic conditions, and our regulatory
compliance requirements. We currently estimate capital expenditures to comply
with environmental regulations will be about $20 million in 2021. Our estimated
environmental expenditures could vary significantly depending upon the enactment
of new environmental laws and regulations, including those related to greenhouse
gas emissions and industrial boilers. For additional information, see
"Environmental Matters" in "Part II, Item 7. Management's Discussion and
Analysis of Financial Condition and Results of Operations" of our 2020 Annual

Reconciliations of Non-GAAP Financial Measures to Reported Amounts



Income from operations excluding special items, net income excluding special
items, EBITDA, and EBITDA excluding special items are non-GAAP financial
measures. Management excludes special items, as it believes that these items are
not necessarily reflective of the ongoing operations of our business. These
measures are presented because they provide a means to evaluate the performance
of our segments and our Company on an ongoing basis using the same measures that
are used by our management, because these measures assist in providing a
meaningful comparison between periods and because these measures are frequently
used by investors and other interested parties in the evaluation of companies
and the performance of their segments. Any analysis of non-GAAP financial
measures should be done in conjunction with results presented in accordance with
GAAP. The non-GAAP measures are not intended to be substitutes for GAAP
financial measures and should not be used as such. Reconciliations of the
non-GAAP measures to the most comparable measure reported in accordance with
GAAP for the three months ended March 31, 2021 and 2020 follow (dollars in
millions):

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. We periodically enter into derivatives to
minimize these risks, but not for trading purposes. We were not a party to any
derivatives-based arrangements at March 31, 2021. For a discussion of
derivatives and hedging activities, see Note 15, Derivative Instruments and
Hedging Activities, of the Notes to Consolidated Financial Statements in "Part
II, Item 8. Financial Statements and Supplementary Data" of our 2020 Annual
Report on Form 10-K.

At March 31, 2021, interest rates on 100% of PCA's outstanding debt are fixed.

Off-Balance-Sheet Activities

The Company does not have any off-balance sheet arrangements as of March 31, 2021.



Environmental Matters

There have been no material changes to the disclosure set forth in Item 7. "Management's Discussion and Analysis of Financial Condition and Results of Operations - Environmental Matters" filed with our 2020 Annual Report on Form 10-K.

Critical Accounting Policies and Estimates



Management's discussion and analysis of financial condition and results of
operations are based upon the Company's 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, PCA evaluates its
estimates, including those related to business combinations, pensions and other
postretirement benefits, goodwill and intangible assets, long-lived asset
impairment, environmental liabilities, and income taxes, among others. PCA bases
its 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.

                                       22

--------------------------------------------------------------------------------

PCA has included in its 2020 Annual Report on Form 10-K a discussion of its critical accounting policies and estimates which require management's most difficult, subjective, or complex judgments used in the preparation of its consolidated financial statements. PCA has not had any changes to these critical accounting estimates during the first three months of 2021.

New and Recently Adopted Accounting Standards

For a listing of our new and recently adopted accounting standards, see Note 2, New and Recently Adopted Accounting Standards, of the Condensed Notes to Unaudited Quarterly Consolidated Financial Statements in "Part I, Item 1. Financial Statements" of this Form 10-Q.

Forward-Looking Statements



Some of the statements in this Quarterly Report on Form 10-Q, and in particular,
statements found in this 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. Forward-looking statements include statements
about our expectations regarding our future liquidity, earnings, expenditures,
and financial condition. 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;

• the impact of the COVID-19 pandemic on the health of our employees, on our

vendors and customers and on economic conditions affecting our business;

• the impact of acquired businesses and risks and uncertainties regarding

operation, expected benefits and integration of such businesses;

• containerboard, corrugated products, and white paper general industry


        conditions, including competition, product demand, product pricing, and
        input costs;


  • fluctuations in wood fiber and recycled fiber costs;


  • fluctuations in purchased energy costs;

• the possibility of unplanned outages or interruptions at our principal

facilities;

• legislative or regulatory actions or requirements, particularly concerning

environmental or tax 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 occur,
what impact they will have on our results of operations or financial condition.
Given these uncertainties, investors are cautioned not to place undue reliance
on these forward-looking statements. We expressly disclaim any 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 our Annual Report on Form 10-K for the year ended
December 31, 2020.
