OVERVIEW

Martin Marietta Materials, Inc. (the Company or Martin Marietta) is a natural
resource-based building materials company. The Company supplies aggregates
(crushed stone, sand and gravel) through its network of approximately 300
quarries, mines and distribution yards in 27 states, Canada and The Bahamas. In
the southwestern and western United States, 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. 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.

Effective January 1, 2020, the Company moved the management of its one quarry in
the state of Washington from the Mid-America Group to the West Group, resulting
in an immaterial change to its reportable segments. During the period covered by
this report, the Company conducted its Building Materials business through three
reportable business segments: Mid-America Group, Southeast Group and West Group.

        MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND

                             RESULTS OF OPERATIONS

                       Second Quarter Ended June 30, 2020

                                  (Continued)



RESULTS OF OPERATIONS

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 and paving 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 and
southwest. 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 on the Company's operations
of weather and the coronavirus (COVID-19) pandemic, including governmental
responses to prevent further outbreak of COVID-19 and other matters, current
period results are not indicative of expected performance for other interim
periods or the full year.

Earnings before interest; income taxes; depreciation, depletion and
amortization; and the earnings/loss from nonconsolidated equity affiliates
(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
and, as such, should not be construed as an alternative to net earnings,
operating earnings or operating cash flow. 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 attributable to Martin Marietta to consolidated Adjusted EBITDA is as follows:

(1) Volume/pricing variances reflect the percentage increase/(decrease) from the comparable period in the prior year.

(2) Total aggregates operations include acquisitions from the date of acquisition and divestitures through the date of disposal.

Mid-America Group shipments decreased 7.2%, driven by near-record rainfall
across much of its footprint, limited COVID-19 impacts and anticipated lower
infrastructure shipments in portions of North Carolina. Geographic mix limited
pricing growth to 2.3% as the Central Division, which has lower selling prices
relative to the consolidated average, contributed a higher percentage of
second-quarter shipments to the Group. Shipments for the Southeast Group
increased 3.0%, as the Florida Department of Transportation (DOT) accelerated
certain transportation projects to leverage construction efficiencies driven by
lower vehicle traffic during the COVID-19 shelter-in-place orders, along with
continued strength in warehouse, data center and distribution facility
construction. These favorable trends were partially offset by weather-impacted
construction delays. Product mix, reflecting a higher percentage of lower-priced
base shipments, limited pricing growth to 0.7%. West Group shipments decreased
1.0%, with double-digit growth in North Texas and Colorado offset by the
completion of certain Gulf Coast liquefied natural gas (LNG) projects and
reduced energy-sector shipments. Pricing improved 5.5%.

Aggregates End-Use Markets

Aggregates shipments to the infrastructure market increased modestly. The
Company benefited from large transportation projects in Texas, Colorado and
Florida, as most state DOTs continued to advance transportation projects during
the COVID-19 shelter-in-place orders. However, consistent with expectations
prior to COVID-19, North Carolina DOT temporarily suspended awards for certain
transportation projects in response to funding issues specific to
weather-related disaster spending and Map Act settlements. The infrastructure
market accounted for 38% of second-quarter aggregates shipments, which is below
the Company's most recent ten-year annual average of 45%.

Aggregates shipments to the nonresidential market declined following double-digit growth in commercial and heavy industrial construction activity in the prior-year quarter. Precipitation and temporary project delays hindered otherwise

robust distribution center, warehouse and data center construction activity. The
Company also experienced reduced energy-related shipments due to the completion
of certain windfarm and LNG projects, as well as lower overall demand to the
shale sector. The nonresidential market represented 32% of second-quarter
aggregates shipments.

Aggregates shipments to the residential market increased, with notable growth
throughout Texas, as well as in Denver and Charlotte. Following a brief
COVID-19-related pause in activity by national homebuilders, housing
construction returned to pre-COVID levels, reflective of pent-up demand, low
available inventories and favorable interest rates. The residential market
accounted for 24% of second-quarter aggregates shipments.

The ChemRock/Rail market accounted for the remaining 6% of second-quarter aggregates shipments. Volumes to this end use increased, driven by improved ballast shipments to the Class I western railroads.

Building Materials Business Product Lines



Second-quarter aggregates shipments declined 3.7% compared with prior-year
quarter volumes that benefited from carryover work from an extraordinarily wet
2018. Near-record wet weather resulted in a double-digit shipment decline in the
Mid-Atlantic division. Pricing improved 3.3% compared with the prior-year
quarter, with all divisions contributing to the growth. Aggregates product gross
margin increased 230 basis points to 35.5%, largely driven by improved pricing,
production efficiencies and lower diesel fuel costs.

Second-quarter cement shipments decreased 2.7%, driven by reduced demand for
West Texas oil-well specialty cement products caused by historically low oil
prices. While cement pricing increased in North Texas, Houston, and portions of
Central Texas, notably lower sales of higher-priced oil-well specialty cement
products limited overall pricing growth to 0.1% compared with prior-year
quarter. Cement product gross margin expanded 210 basis points over the
prior-year quarter to 39.7%, driven by reduced fuel costs and improved kiln
reliability.

Ready mixed concrete shipments and pricing improved 0.3% and 1.3%, respectively,
in the second quarter compared with the prior-year quarter. Shipments in the
prior-year quarter included 168,000 cubic yards from the Southwest Ready Mix
Division's business in the Arkansas, Louisiana and eastern Texas (ArkLaTex)
areas that was divested in January 2020. Excluding these divested operations in
the prior period, shipment volumes increased 8.7%. Lower delivery expenses and
improved leveraging of costs along with cost reduction initiatives drove a
270-basis-point increase in gross margin. Asphalt volume increased 34.6% versus
an extremely weather-challenged prior-year quarter. Asphalt pricing decreased
1.4% due to unfavorable product mix from a higher percentage of shipments to
lower-priced municipal projects.

Magnesia Specialties Business



Magnesia Specialties product revenues decreased 30.6% to $48.9 million. Lime and
periclase shipments to the steel industry declined in response to the
COVID-19-induced shutdown of domestic auto manufacturers. Additionally, domestic
and international demand for chemicals products slowed due to COVID-19. Product
gross profit was $18.2 million compared with $29.2 million. Product gross margin
was 37.3% compared with 41.5%. Second-quarter earnings from operations were
$13.2 million in 2020 compared with $25.2 million in 2019.

Consolidated Operating Results



Consolidated SG&A for second quarter 2020 was 5.6% of total revenues compared
with 5.7% in the prior-year quarter. During second-quarter 2020, the Company
incurred $3.4 million in COVID-19 related expenses for enhanced cleaning and
sanitizing protocols across the Company's operations, which are recorded in
SG&A. Earnings from operations for the quarter were $306.4 million in 2020
compared with $285.9 million in 2019.

Among other items, other operating income and expenses, 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 second quarter, consolidated other operating income and
expenses, net, was an expense of $2.4 million in 2020 and income of $1.4 million
in 2019. The income in 2019 reflected the reversal of $4.2 million of accruals
for unclaimed property contingencies.

Other nonoperating income and expenses, 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 second quarter,
other nonoperating expenses and income, net, was income of $3.8 million and
expense of $13.2 million in 2020 and 2019, respectively. The expense in 2019 was
primarily due to a $15.7 million ($12.0 million net of tax) out-of-period
correction of a Company-identified overstatement of the investment balance for a
nonconsolidated equity affiliate.

For the six months ended June 30, 2020, aggregates shipments to the infrastructure market accounted for 36% of year-to-date aggregates volumes and increased modestly, driven by large projects in Texas and Colorado, and partially offset by lower volumes in North Carolina.



Aggregates shipments to the nonresidential market declined following
double-digit growth in commercial and heavy industrial construction activity,
namely in Iowa and Texas, in the prior-year period. Additionally, energy-sector
shipments declined, driven by historically low oil prices. The nonresidential
market represented 33% of year-to-date aggregates shipments.

                                  (Continued)



Following a slowdown in the residential market due to rainfall in the first
quarter and COVID-19, aggregates shipments to the residential market increased
during the spring selling season due to pent-up housing demand and emerging
homebuying trends as prospective buyers look to move to small metro or suburban
locations. The residential market accounted for 24% of year-to-date aggregates
shipments.

The ChemRock/Rail market accounted for the remaining 7% of year-to-date aggregates shipments. Volumes to this end use increased, driven by improved ballast shipments to the Class I western railroads.

Building Materials Business Product Lines



For the six months ended June 30, 2020, aggregates shipments decreased 1.2% as
prior year volumes benefited from carryover work from 2018. Pricing increased
3.1% compared with the prior-year period. Aggregates product gross margin
improved 50 basis points to 27.3%.

For the six months ended June 30, 2020, cement shipments and pricing increased
1.1% and 1.3%, respectively, compared with the prior-year period. Production
efficiencies, lower fuel costs and improved kiln reliability contributed to the
620-basis-point expansion in cement product gross margin to 32.7%.

Ready mixed concrete pricing improved 2.8% while shipments declined 6.5% in the
first half of the year as compared with the prior-year period. The volume
decline is attributable to the divestiture of the Southwest Ready Mix Division's
ArkLaTex operations in January 2020, which accounted for 300,000 cubic yards in
the prior-year period. Excluding ArkLaTex shipments from the prior period,
volumes were flat. Asphalt volume increased 39.6% attributable to favorable
weather compared with the prior-year period. Asphalt pricing decreased 1.5% due
to unfavorable product mix.

Magnesia Specialties Business



For the six months ended June 30, 2020, Magnesia Specialties reported product
revenues of $108.8 million compared with $139.5 million for the prior-year
period. Year over year revenue decline is attributable to lower lime and
periclase shipments to the steel industry in response to the COVID-19-induced
shutdown of domestic auto manufacturers. Additionally, the business experienced
a continued decline in chemicals products sales as both domestic and
international customers experienced a downturn in economic activity related to
COVID-19. Product gross profit was $44.3 million compared with $55.8 million.
Product gross margin improved 70 basis points to 40.7% over the six months ended
June 30, 2019. Earnings from operations were $34.9 million compared with $47.9
million.

Consolidated Operating Results



For the six months ended June 30, 2020, consolidated SG&A was 6.7% of total
revenues compared with 6.8% in 2019. During the first six months of 2020, the
Company incurred $3.5 million in COVID-19 related expenses for enhanced cleaning
and sanitizing protocols across the Company's operations, which are recorded in
SG&A. Earnings from operations for the six months ended June 30 were $364.2
million in 2020 compared with $355.1 million in 2019. Among other items, other
operating income and expenses, 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 six months
ended June 30, consolidated other operating income and expenses, net, was an
expense of $8.0 million and income of $6.2 million in 2020 and 2019,
respectively. The 2020 amount reflected a $2.5 million increase in credit loss
expenses and a $2.8 million increase in asset reclamation costs compared with
the prior-year period. The 2019 amount included the reversal of $4.2 million of
accruals for unclaimed property contingencies. Other nonoperating income and
expenses, net, includes interest

currency transaction gains and losses; equity in earnings or losses of
nonconsolidated affiliates and other miscellaneous income. For the six months
ended June 30, other nonoperating income and expenses, net, was income of $1.9
million in 2020 and an expense of $11.7 million in 2019. The 2020 amount
included an expense of $5.6 million for third-party railroad track maintenance.
The 2019 expense included a $15.7 million ($12.0 million net of tax)
out-of-period correction of a Company-identified overstatement of the investment
balance for a nonconsolidated equity affiliate.

Income Tax Expense



For the six months ended June 30, 2020, the effective income tax rate reflected
a $6.9 million discrete benefit from financing third-party railroad track
maintenance. In exchange, the Company received a federal income tax credit and
deduction. For the six months ended June 30, 2019, the effective income tax rate
reflected a $13.2 million discrete benefit from a change in the tax status of a
subsidiary from a partnership to a corporation.

LIQUIDITY AND CAPITAL RESOURCES



For the six months ended June 30, cash provided by operating activities was
$373.2 million in 2020 compared with $333.7 million in 2019. 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:

Total          $      193.4       $ 182.0




The seasonal nature of construction activity impacts the Company's quarterly
operating cash flow when compared with the full year. Full-year 2019 net cash
provided by operating activities was $966.1 million.

During the six months ended June 30, 2020, the Company paid $175.7 million for capital investments.



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 210,616 shares of common stock during
the first six months of 2020, at an aggregate cost of $50.0 million. Future
share repurchases are at the discretion of management and were temporarily
paused in March 2020 in light of the COVID-19 pandemic. Management may resume
share repurchases as circumstances dictate. At June 30, 2020, 13,520,952 shares
of common stock were remaining under the Company's repurchase authorization.

On March 5, 2020, the Company issued $500 million aggregate principal amount of
2.500% Senior Notes due 2030 (the 2.500% Senior Notes). The 2.500% Senior Notes
are carried net of original issue discount, which is being amortized by the
effective interest method over the life of the issue. The 2.500% Senior Notes
are redeemable prior to December 15, 2029 at their make-whole redemption price
at a discount rate of the U.S. Treasury Rate plus 30 basis points, or on or
after December 15, 2029 at a redemption price equal to 100% of the principal
amount plus accrued and unpaid interest to the date of redemption. The Company
used the net proceeds for general corporate purposes, including the repayment of
$300 million of floating rate senior notes due at maturity in May 2020.

The Company has a $700 million five-year senior unsecured revolving facility
(the Revolving Facility), which expires on December 5, 2024. 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 3.50x 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 3.75x. Additionally, if there
are no amounts outstanding under the Revolving Facility and the $400 million
trade receivable securitization facility (the Trade Receivable Facility) held by
the Company's wholly-owned special-purpose subsidiary, consolidated debt,
including debt for which the Company is a co-borrower, may be reduced by the
Company's unrestricted cash and cash equivalents in excess of $50 million, such
reduction not to exceed $200 million, for purposes of the covenant calculation.

The Ratio is calculated as debt, including debt for which the Company is a
co-borrower, divided by consolidated EBITDA, as defined by the Company's
Revolving Facility, for the trailing-twelve months. Consolidated EBITDA is
generally defined as earnings before interest expense, income tax expense, and
depreciation and amortization expense. Additionally, stock-based compensation
expense is added back and interest income is deducted in the calculation of
consolidated EBITDA. During periods that include an acquisition, pre-acquisition
adjusted EBITDA of the acquired company is added to consolidated EBITDA as if
the acquisition occurred on the first day of the calculation period. Certain
other nonrecurring items, if they occur, can affect the calculation of
consolidated EBITDA.

At June 30, 2020, the Company's ratio of consolidated debt-to-consolidated EBITDA, as defined by the Company's Revolving Facility, for the trailing-twelve months was 2.11 times and was calculated as follows:

The Trade Receivable Facility contains a cross-default provision to the
Company's other debt agreements. 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. Outstanding amounts on the
Trade Receivable Facility have been classified as a current liability on the
Company's consolidated balance sheets.

Cash on hand, 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 when the
repurchase program is resumed and allow for payment of dividends for the
foreseeable future. Any future significant strategic acquisition for cash would
likely require an appropriate balance of newly-issued equity with debt in order
to maintain a composite investment-grade credit rating. At June 30, 2020, the
Company had $967.7 million of unused borrowing capacity under its Revolving
Facility and Trade Receivable Facility, subject to complying with the related
leverage covenant. The Revolving Facility matures on December 5, 2024 and the
Trade Receivable Facility expires September 23, 2020. Historically, the Company
has successfully extended the maturity dates of these credit
facilities. Further, as of June 30, 2020, the Company does not have any
publicly-traded debt that matures prior to 2024. While the future impact of the
COVID-19 pandemic is not currently quantifiable, management believes the
Company's liquidity is sufficient to meet its cash flow needs through the
foreseeable future.

The Coronavirus Aid, Relief and Economic Security Act (CARES Act) was signed
into law in March 2020 and provides liquidity support for businesses. The CARES
Act allows the Company to defer the payment of 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 will be due December 31, 2021 and the
remaining half will be due December 31, 2022. There will be no interest assessed
on amounts deferred. The Company estimates it will defer payment of
approximately $25 million under this provision.

The CARES Act also provides a quarterly refundable employee retention credit if
companies suspend operations due to government restrictions or experience a 50%
or more decline in quarterly revenues compared with the prior-year quarter. The
credit is equal to 50% of qualified wages, up to $10,000 per employee who is not
performing services for the Company. While the Company has had minimal
short-term shutdowns related to the COVID-19 pandemic such that the Company has
not utilized this aid, if future shutdowns are mandated and more extensive, the
Company would be eligible to claim this credit.

The CARES Act also includes other provisions, including increasing the interest
expense deduction limitation to 50% of adjusted taxable income and providing a
credit facility for investment-grade companies. The Company does not currently
expect the interest expense deduction provision to result in a change in its
ability to take a full income tax deduction. The Company also believes it has
adequate liquidity and does not currently expect to utilize the credit facility
under the CARES Act.

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, 2019. Management continues to
