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



OVERVIEW

Martin Marietta Materials, Inc. (the Company or Martin Marietta) is a natural
resource-based building materials company. As of September 30, 2022, the Company
supplies aggregates (crushed stone, sand and gravel) through its network of
approximately 350 quarries, mines and distribution yards in 28 states, Canada
and The Bahamas. Martin Marietta also provides cement and downstream products
and services, namely, ready mixed concrete, asphalt and paving, in
vertically-integrated structured markets where the Company has a leading
aggregates position. In addition, the Company has one cement plant, cement
distribution terminals and ready mixed concrete operations in California that
are classified as assets held for sale and reported as discontinued operations
as of and for the nine months ended September 30, 2022. The Company's heavy-side
building materials are used in infrastructure, nonresidential and residential
construction projects. Aggregates are also used in agricultural, utility and
environmental applications and as railroad ballast. The aggregates, cement,
ready mixed concrete and asphalt and paving product lines are reported
collectively as the "Building Materials" business.

The Company's Building Materials business includes two reportable segments: the East Group and the West Group.

The Building Materials business is significantly affected by weather patterns
and seasonal changes. Production and shipment levels for aggregates, cement,
ready mixed concrete and asphalt materials correlate with general construction
activity levels, most of which occur in the spring, summer and fall. Thus,
production and shipment levels vary by quarter. Operations concentrated in the
northern and midwestern United States generally experience more severe winter
weather conditions than operations in the Southeast, Southwest and West.
Excessive rainfall, and conversely excessive drought, can also jeopardize
production, shipments and profitability in all markets served by the Company.
Due to the potentially significant impact of weather on the Company's
operations, current-period results are not necessarily indicative of expected
performance for other interim periods or the full year.

                    For the Quarter Ended September 30, 2022

        MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
                             RESULTS OF OPERATIONS
                                  (Continued)

The Company has a Magnesia Specialties business with manufacturing facilities in
Manistee, Michigan, and Woodville, Ohio. The Magnesia Specialties business
produces magnesia-based chemicals products used in industrial, agricultural and
environmental applications and dolomitic lime sold primarily to customers in the
steel and mining industries.

CRITICAL ACCOUNTING POLICIES

The Company outlined its critical accounting policies in its Annual Report on
Form 10-K for the year ended December 31, 2021. There were no changes to the
Company's critical accounting policies during the nine months ended September
30, 2022.

RESULTS OF OPERATIONS

Earnings from continuing operations before interest; income taxes; depreciation,
depletion and amortization; the earnings/loss from nonconsolidated equity
affiliates; acquisition and integration expenses; the impact of selling acquired
inventory after markup to fair value as part of acquisition accounting; and the
nonrecurring gain on the divestiture of certain ready mixed concrete operations
(Adjusted EBITDA) is an indicator used by the Company and investors to evaluate
the Company's operating performance from period to period. Adjusted EBITDA is
not defined by accounting principles generally accepted in the United States
(GAAP) and, as such, should not be construed as an alternative to net earnings,
earnings from operations or cash provided by operating activities. However, the
Company's management believes that Adjusted EBITDA may provide additional
information with respect to the Company's performance and is a measure used by
management to evaluate the Company's performance. Because Adjusted EBITDA
excludes some, but not all, items that affect net earnings and may vary among
companies, Adjusted EBITDA as presented by the Company may not be comparable
with similarly titled measures of other companies.

A reconciliation of net earnings from continuing operations attributable to Martin Marietta to Adjusted EBITDA is as follows:

Adjusted consolidated earnings from operations and adjusted earnings per diluted
share from continuing operations represent non-GAAP financial measures and
exclude acquisition and integration expenses; the impact of selling acquired
inventory after its markup to fair value as part of acquisition accounting; and
the impact of the nonrecurring gain on the divestiture of certain ready mixed
concrete operations. Management presents these measures for investors to
evaluate and forecast the Company's results, as the impact of these items are
nonrecurring.

A reconciliation of consolidated earnings from operations to adjusted consolidated earnings from operations is as follows:

Mix-adjusted average selling price (mix-adjusted ASP) excludes the impacts of
product, geographic and other mix from the current-period average selling price
and is a non-GAAP measure. Mix-adjusted ASP is calculated by comparing
current-period shipments to like-for-like shipments in the comparable prior
period. Management uses this metric to evaluate the effectiveness of the
Company's pricing increases and believes this information is useful to investors
as it provides same-on-same pricing trends.

Aggregates End-Use Markets

Organic aggregates shipments to the infrastructure market remained flat,
reflecting increased highway construction activity in North Carolina, Colorado,
Georgia and Indiana which was offset by project delays and projects coming to
completion in Texas. The infrastructure market accounted for 36% of
third-quarter organic aggregates shipments.

Organic aggregates shipments to the nonresidential market increased 2%, driven
by several large manufacturing, data center and energy projects in Georgia,
North Carolina, Iowa and Texas. The nonresidential market represented 35% of
third-quarter organic aggregates shipments.

Organic aggregates shipments to the residential market decreased 3%. Despite
overall underbuilt conditions, several markets experienced a slowdown in this
end use due to affordability concerns and logistical challenges. The residential
market accounted for 24% of third-quarter organic aggregates shipments.

The ChemRock/Rail market accounted for the remaining 5% of third-quarter organic
aggregates shipments. Volumes to this end use increased 4%, driven by increased
ballast shipments.

Building Materials Business

Third-quarter organic aggregates shipments were flat, due to logistical
constraints and cement shortages as well as inclement weather in certain key
markets. Organic pricing increased 11.9%, or 11.3% on a mix-adjusted basis, over
the prior-year quarter as the Company continued to benefit from price increases.
Including acquired operations, total aggregates shipments and pricing grew 5.6%
and 11.6%, respectively. East Group total shipments were flat, as strong
underlying demand was negatively impacted by logistical bottlenecks and
weather-related disruptions. East Group pricing increased 11.5%. West Group
total shipments improved 15.6%, driven primarily by contributions from acquired
operations and strong Texas demand, partially offset by historically wet weather
in North Texas in the month of August. West Group pricing, inclusive of
acquisitions, increased 12.2%. West Group organic pricing increased 12.4%, or
13.2% on a mix-adjusted basis. Third-quarter aggregates product gross profit
improved 12.8% to $330.3 million, while product gross margin declined 170 basis
points to 32.5%, primarily due to increased energy, internal freight and repairs
and maintenance costs.

Cement shipments of 1.1 million tons increased 2.3% driven by continued strong
demand. Pricing increased 21.4%, or 20.6% on a mix-adjusted basis, following
multiple price increases in Texas. Cement product gross profit grew to $67.7
million, an increase of 35.8%, and product gross margin expanded 380 basis
points to 41.5%, as pricing gains more than offset higher energy costs in the
period.

On an organic basis, ready mix shipments were down 16.8%, largely due to
significant rainfall in Texas during August as well as the completion of certain
large projects. Organic pricing increased 20.3% due to multiple price increases
implemented during the year. Ready mix product revenues and gross profit from
continuing operations declined 29.1% and 40.3%, respectively, driven primarily
by the divestiture of the Company's Colorado and Central Texas ready mixed
concrete businesses on April 1, which was partially offset by acquired
operations in Arizona.

Including contributions from the acquired West Coast operations, total asphalt
shipments and pricing increased 31.3% and 26.1%, respectively. On an organic
basis, total asphalt shipments and pricing increased 4.3% and 22.0%,
respectively. Total asphalt and paving products and services gross profit
increased to a record $50.5 million. However, continued acceleration of liquid
asphalt, or bitumen, costs contributed to products and services gross margin
compression of 360 basis points in the third quarter.

Magnesia Specialties Business



Magnesia Specialties third-quarter product revenues decreased 4.0% to $69.0
million, driven largely by lower demand in the steel industry for dolomitic lime
products. Product gross profit declined 22.9% to $21.6 million, as higher energy
costs, particularly natural gas, depressed gross margin in the quarter.

Consolidated Operating Results

Consolidated SG&A for third quarter 2022 was 5.2% of total revenues compared with 5.5% in the prior-year quarter, a 30-basis-point improvement.



Among other items, other operating income, net, includes gains and losses on the
sale of assets; recoveries and write-offs related to customer accounts
receivable; rental, royalty and services income; and accretion expense,
depreciation expense and gains and losses related to asset retirement
obligations. For the third quarter, consolidated other operating income, net,
was income of $14.8 million in 2022 and $8.4 million in 2021, with the increase
driven by higher gains on sales of surplus land and other assets.

Earnings from operations for the quarter were $405.9 million in 2022 compared
with $356.9 million in 2021, with the increase driven by year-over-year price
increases, partially offset by higher costs for energy, supplies, and freight.

Aggregates End-Use Markets

Organic aggregates shipments to the infrastructure market increased 4%, primarily driven by increased highway construction activity across many of the Company's key markets. The infrastructure market accounted for 35% of year-to-date organic aggregates shipments.



Organic aggregates shipments to the nonresidential market increased 1%, driven
by several large warehouse projects in the Central and Southwest Divisions,
partially offset by several large projects in the West Division that were not
replaced in the current period. The nonresidential market represented 35% of
year-to-date organic aggregates shipments.

Organic aggregates shipments to the residential market remained flat compared with strong prior-year activity, but slowed in the third quarter. The residential market accounted for 25% of year-to-date organic aggregates shipments.



The ChemRock/Rail market accounted for the remaining 5% of year-to-date organic
aggregates shipments. Volumes to this end use increased 4%, driven by increased
ballast shipments for a large project and increased agricultural lime shipments.

        MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
                             RESULTS OF OPERATIONS
                                  (Continued)


Building Materials Business

Year-to-date organic aggregates shipments increased 2.0%, reflecting healthy
underlying public product demand partially constrained by logistics-related
bottlenecks and inclement weather in certain key markets. Organic aggregates
pricing increased 9.4%, or 8.6% on a mix-adjusted basis. Inclusive of acquired
operations, aggregates shipments grew 8.9% and pricing also increased 8.9%, both
compared with the comparable prior-year period. East Group total shipments
remained flat, reflecting healthy construction activity that was offset by
logistical bottlenecks and weather-related disruptions, while pricing increased
8.5%. West Group total shipments increased 25.2%, driven by robust underlying
demand in Texas and shipments from acquired operations. West Group pricing,
inclusive of acquisitions, increased 11.0%, while organic West Group pricing
increased 11.5%, or 9.7% on a mix-adjusted basis, reflecting price increases and
a larger percentage of shipments from higher-priced distribution yards.
Aggregates product gross margin decreased 290 basis points to 27.9%, as the
impact from year-over-year price increases were more than offset by higher costs
for energy, fuel, supplies, repairs and contract services.

Texas cement shipments increased 10.3% year-to-date, supported by robust product
demand. Cement pricing improved 16.1%, or 15.5% on a mix-adjusted basis,
benefitting from multiple price increases. Product gross margin expanded 380
basis points to 32.1% compared with the prior-year period, as shipment and
pricing growth more than offset energy and other cost headwinds.

Organic ready mixed concrete shipments decreased 5.4%. Organic pricing grew
15.2% in the first nine months of 2022 compared with 2021. Consolidated ready
mixed concrete shipments decreased 17.4%, primarily reflecting the impact of
divested operations, partially offset by contributions from acquired ready mix
operations in Arizona, and pricing increased 9.4%. Product gross margin declined
120 basis points to 7.3%, driven primarily by higher raw material costs which
more than offset price increases.

Organic asphalt shipments increased 2.6%. Organic asphalt pricing increased
19.7%. Including contributions from the acquired West Coast operations, total
asphalt shipments and pricing increased 46.1% and 25.5%, respectively. Product
and services gross margin decreased 630 basis points to 11.0%, driven by higher
liquid asphalt and energy costs.

Magnesia Specialties Business



Magnesia Specialties product revenues increased 3.5% to $214.4 million for the
nine months ended September 30, 2022, driven by robust global demand for
magnesia-based chemical products. Product gross profit was $74.3 million
compared with $84.4 million. Product gross margin decreased 610 basis points to
34.6%, as higher costs for energy, supplies and raw materials more than offset
pricing growth.

Consolidated Operating Results

Consolidated SG&A for nine months ended September 30 was 6.3% of total revenues in 2022 and 2021.



Among other items, other operating income, net, includes gains and losses on the
sale of assets; recoveries and write-offs related to customer accounts
receivable; rental, royalty and services income; accretion expense, depreciation
expense and gains and losses related to asset retirement obligations. For the
nine months ended September 30, consolidated other operating income, net, was
income of $177.4 million in 2022 and $28.2 million in 2021. The increase in
other operating income, net, was primarily attributable to the $151.9 million
gain on the divestiture of the Colorado and Central Texas ready mixed concrete
operations. Other operating income, net, for the nine months ended September 30,
2021 included a $12.3 million gain on the sale of the Company's former corporate
headquarters.

Earnings from operations for the nine months ended September 30 were $944.4 million in 2022 compared with $763.7 million in 2021, with the increase driven by the $151.9 million gain on the divestiture of the Colorado and Central Texas

ready mixed concrete operations and year-over-year price increases, partially offset by higher costs for energy, fuel, supplies, freight and personnel.



Other nonoperating income, net, includes interest income; pension and
postretirement benefit cost excluding service cost; foreign currency transaction
gains and losses; equity earnings or losses from nonconsolidated affiliates; and
other miscellaneous income and expenses. For the nine months ended September 30,
other nonoperating income, net, was $40.1 million and $23.8 million in 2022 and
2021, respectively. The 2022 amount included a $12.0 million pretax gain related
to repurchases of the Company's debt.

Income Tax Expense



For the nine months ended September 30, 2022 and 2021, the effective income tax
rates for continuing operations were 22.1% and 20.6%, respectively. The higher
2022 effective income tax rate versus 2021 was driven by the impact of the
divestiture of the Colorado and Central Texas ready mixed concrete businesses.

LIQUIDITY AND CAPITAL RESOURCES



Cash provided by operating activities for the nine months ended September 30,
2022 and 2021 was $560.7 million and $780.3 million, respectively, driven by
increased cash taxes and changes in working capital. Operating cash flow is
primarily derived from consolidated net earnings before deducting depreciation,
depletion and amortization, and the impact of changes in working capital.
Depreciation, depletion and amortization were as follows:

                   Nine Months Ended
                     September 30,
                   2022            2021

Depreciation   $       296.9      $ 262.1
Depletion               45.9         29.5
Amortization            37.5         28.4
Total          $       380.3      $ 320.0

The seasonal nature of construction activity impacts the Company's interim operating cash flow when compared with the full year. Full-year 2021 net cash provided by operating activities was $1.14 billion.

During the nine months ended September 30, 2022 and 2021, the Company paid $309.1 million and $321.3 million, respectively, for capital investments. In October 2022, the Company entered into a commitment for 691 railcars at an aggregate value of $75.8 million.



The Company can repurchase its common stock through open-market purchases
pursuant to authority granted by its Board of Directors or through private
transactions at such prices and upon such terms as the Chief Executive Officer
deems appropriate. The Company repurchased 418,336 shares of common stock during
the first nine months of 2022 at an aggregate cost of $150.0 million. At
September 30, 2022, 13,102,616 shares of common stock can be purchased under the
Company's repurchase authorization.

During the nine months ended September 30, 2022, the Company repurchased $67.7
million (par value) of its Senior Notes, resulting in a pretax gain of $12.0
million.

On September 29, 2022, the Company satisfied and discharged its 0.650% Senior
Notes due 2023 (the 2023 Notes). In connection with the satisfaction and
discharge, the Company irrevocably deposited with Regions Bank (the Trustee)
funds in an amount sufficient to satisfy all remaining principal and interest
payments on the 2023 Notes. The funds are invested in a fund that invests
exclusively in U.S. Treasury securities and are classified as Restricted
investments (to satisfy discharged debt and related interest) on the
consolidated balance sheet at September 30, 2022. Holders of the 2023 Notes will
receive payment of principal on the scheduled maturity date and payment of
interest at the per annum rate (and on the dates) set forth in the 2023 Notes
indenture. The Company utilized existing cash resources to fund the satisfaction
and discharge. As a result of the satisfaction and discharge of the 2023 Notes,
the obligations of the Company under the indenture in respect of the 2023 Notes
have been terminated, except those provisions of the indenture that, by their
terms, survive the satisfaction and discharge. The 2023 Notes remain on the
Company's consolidated balance sheet at September 30, 2022 and will continue to
accrete to their par value over the period until maturity in July 2023.

The Company, through a wholly-owned special-purpose subsidiary, has a $400 million trade receivable securitization facility (the Trade Receivable Facility). On September 21, 2022, the Company extended the maturity of the Trade Receivable Facility to September 20, 2023. The Trade Receivable Facility contains a cross-default provision to the Company's other debt agreements.



The Company has an $800 million five-year senior unsecured revolving facility
(the Revolving Facility), which expires in December 2026. The Revolving Facility
requires the Company's ratio of consolidated debt-to-consolidated EBITDA, as
defined, for the trailing-twelve-month period (the Ratio) to not exceed 3.50
times as of the end of any fiscal quarter, provided that the Company may exclude
from the Ratio debt incurred in connection with certain acquisitions during the
quarter or the three preceding quarters so long as the Ratio calculated without
such exclusion does not exceed 4.00 times. Additionally, if there are no amounts
outstanding under the Revolving Facility and the Trade Receivable Facility,
consolidated debt, including debt for which the Company is a guarantor, may be
reduced in an amount equal to the lesser of $500.0 million or the sum of the
Company's unrestricted cash and temporary investments, for purposes of the
covenant calculation. The Company was in compliance with the Ratio at September
30, 2022.

In the event of a default on the Ratio, the lenders can terminate the Revolving
Facility and Trade Receivable Facility and declare any outstanding balances as
immediately due. There were no amounts outstanding under the Trade Receivable
Facility or the Revolving Facility at September 30, 2022.

Cash on hand and restricted investments, along with the Company's projected
internal cash flows and availability of financing resources, including its
access to debt and equity capital markets, is expected to continue to be
sufficient to provide the capital resources necessary to support anticipated
operating needs, cover debt service requirements, address near-term debt
maturities, meet capital expenditures and discretionary investment needs, fund
certain acquisition opportunities that may arise, allow the repurchase of shares
of the Company's common stock and allow for payment of dividends for the
foreseeable future. At September 30, 2022, the Company had $1,197.4 million of
unused borrowing capacity under its Revolving Facility and Trade Receivable
Facility, subject to complying with the related leverage covenant. Historically,
the Company has successfully extended the maturity dates of these credit
facilities.

The Coronavirus Aid, Relief and Economic Security Act (CARES Act) was signed
into law in March 2020 and provided liquidity support for businesses. Through
the CARES Act, the Company deferred payment of $27.6 million, representing the
6.2% employer share of Social Security taxes for the period from March 27, 2020
through December 31, 2020. Half of the deferred obligation was repaid in 2021
and the remaining half is due December 31, 2022. There will be no interest
assessed on amounts deferred.

TRENDS AND RISKS

The Company outlined the risks associated with its business in its Annual Report on Form 10-K for the year ended December 31, 2021. Management continues to evaluate its exposure to all operating risks on an ongoing basis.



On August 16, 2022, the U.S. enacted the Inflation Reduction Act of 2022, which,
among other things, implements a 15% minimum tax on book income of certain large
corporations, a 1% excise tax on net stock repurchases and several tax
incentives to promote clean energy. Based on the Company's current analysis of
the provisions, management does not believe this legislation will have a
material impact on the Company's consolidated financial statements.

OTHER MATTERS



If you are interested in Martin Marietta stock, management recommends that, at a
minimum, you read the Company's current annual report and Forms 10-K, 10-Q and
8-K reports to the Securities and Exchange Commission (SEC) over the past year.
The Company's recent proxy statement for the annual meeting of shareholders also
contains important information. These and other materials that have been filed
with the SEC are accessible through the Company's website at
www.martinmarietta.com and are also available at the SEC's website at
www.sec.gov. You may also write or call the Company's Corporate Secretary, who
will provide copies of such reports.

Investors are cautioned that all statements in this Form 10-Q that relate to the
future involve risks and uncertainties, and are based on assumptions that the
Company believes in good faith are reasonable but which may be materially
different from actual results. These statements, which are forward-looking
statements under the Private Securities Litigation Reform Act of 1995, provide
the investor with the Company's expectations or forecasts of future events. You
can identify these statements by the fact that they do not relate only to
historical or current facts. They may use words such as "anticipate," "may,"
"expect," "should," "believe," "project," "intend," "will," and other words of
similar meaning in connection with future events or future operating or
financial performance. Any or all of management's forward-looking statements
here and in other publications may turn out to be wrong.

The Company's outlook is subject to various risks and uncertainties and is based
on assumptions that the Company believes in good faith are reasonable but which
may be materially different from actual results. Factors that the Company
currently believes could cause actual results to differ materially from the
forward-looking statements in this Form 10-Q include, but are not limited to:
the ability of the Company to face challenges, including shipment declines
resulting from economic events beyond the Company's control; a widespread
decline in aggregates pricing, including a decline in aggregates shipment volume
negatively affecting aggregates price; the history of both cement and ready
mixed concrete being subject to significant changes in supply, demand and price
fluctuations; the termination, capping and/or reduction or suspension of the
federal and/or state gasoline tax(es) or other revenue related to public
construction; the level and timing of federal, state or local transportation or
infrastructure or public projects funding, most particularly in Texas, Colorado,
California, North Carolina, Georgia, Minnesota, Iowa, Florida, Indiana and
Maryland; the United States Congress' inability to reach agreement among
themselves or with the Administration on policy issues that impact the federal
budget; the ability of states and/or other entities to finance approved projects
either with tax revenues or alternative financing structures; levels of
construction spending in the markets the Company serves; a reduction in defense
spending and the subsequent impact on construction activity on or near military
bases; a decline in energy-related construction activity resulting from
suspension of the gas tax or a sustained period of low global oil prices or
changes in oil production patterns or capital spending, particularly in Texas
and West Virginia; increasing residential mortgage interest rates and other
factors that could result in a slowdown in residential construction; unfavorable
weather conditions, particularly Atlantic Ocean and Gulf of Mexico hurricane
activity, wildfires, the late start to spring or the early onset of winter and
the impact of a drought or excessive rainfall in the markets served by the
Company, any of which can significantly affect production schedules, volumes,
product and/or geographic mix and profitability; the volatility of fuel costs,
particularly diesel fuel,

notably related to the current conflict between Russia and Ukraine, and the
impact on the cost, or the availability generally, of other consumables, namely
steel, explosives, tires and conveyor belts, and with respect to the Company's
Magnesia Specialties business, natural gas; continued increases in the cost of
other repair and supply parts; construction labor shortages and/or supply­chain
challenges; unexpected equipment failures, unscheduled maintenance, industrial
accident or other prolonged and/or significant disruption to production
facilities; the resiliency and potential declines of the Company's various
construction end-use markets; the potential negative duration, severity and
impact of a resurgence of the COVID-19 pandemic on the Company's ability to
continue supplying heavy-side building materials and related services at normal
levels or at all in the Company's key regions, including the markets in which it
does business, its suppliers, customers or other business partners as well as on
its employees; the economic impact of government responses to a resurgence of
COVID-19; the performance of the United States economy; the impact of
governmental orders restricting activities imposed to prevent further outbreak
of COVID-19 on travel, potentially reducing state fuel tax revenues used to fund
highway projects; a decline in the commercial component of the nonresidential
construction market, notably office and retail space, including a decline
resulting from economic distress related to the COVID-19 pandemic; increasing
governmental regulation, including environmental laws; the failure of relevant
government agencies to implement expected regulatory reductions; transportation
availability or a sustained reduction in capital investment by the railroads,
notably the availability of railcars, locomotive power and the condition of rail
infrastructure to move trains to supply the Company's Texas, Colorado, Florida,
Carolinas and Gulf Coast markets, including the movement of essential dolomitic
lime for magnesia chemicals to the Company's plant in Manistee, Michigan and its
customers; increased transportation costs, including increases from higher or
fluctuating passed-through energy costs or fuel surcharges, and other costs to
comply with tightening regulations, as well as higher volumes of rail and water
shipments; availability of trucks and licensed drivers for transport of the
Company's materials; availability and cost of construction equipment in the
United States; weakening in the steel industry markets served by the Company's
dolomitic lime products; trade disputes with one or more nations impacting the
U.S. economy, including the impact of tariffs on the steel industry; unplanned
changes in costs or realignment of customers that introduce volatility to
earnings, including that of the Magnesia Specialties business that is running at
capacity; proper functioning of information technology and automated operating
systems to manage or support operations; inflation and its effect on both
production and interest costs; the concentration of customers in construction
markets and the increased risk of potential losses on customer receivables; the
impact of the level of demand in the Company's end-use markets, production
levels and management of production costs on the operating leverage and
therefore profitability of the Company; the possibility that the expected
synergies from acquisitions will not be realized or will not be realized within
the expected time period, including achieving anticipated profitability to
maintain compliance with the Company's leverage ratio debt covenant; changes in
tax laws, the interpretation of such laws and/or administrative practices,
including acquisitions or divestitures, that would increase the Company's tax
rate; violation of the Company's debt covenant if price and/or volumes return to
previous levels of instability; downward pressure on the Company's common stock
price and its impact on goodwill impairment evaluations; the possibility of a
reduction of the Company's credit rating to non-investment grade; and other risk
factors listed from time to time found in the Company's filings with the SEC.

You should consider these forward-looking statements in light of risk factors
discussed in the Company's Annual Report on Form 10-K for the year ended
