                CORE MOLDING TECHNOLOGIES, INC. AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)


1.  PRESENTATION

        The accompanying unaudited consolidated financial statements have been
prepared in accordance with the instructions to Form 10Q and include all of the
information and disclosures required by accounting principles generally accepted
in the United States of America for interim reporting, which are less than those
required for annual reporting. In the opinion of management, the accompanying
unaudited consolidated financial statements contain all adjustments (all of
which are normal and recurring in nature) necessary to present fairly the
financial position of Core Molding Technologies, Inc. and its subsidiaries
("Core Molding Technologies") at September 30, 2003, and the results of their
operations and cash flows. The "Consolidated Notes to Financial Statements",
which are contained in the 2002 Annual Report to Shareholders, should be read in
conjunction with these Consolidated Financial Statements. Certain
reclassifications have been made to prior year's amounts to conform to the
classifications of such amounts for 2003.

        Core Molding Technologies and its subsidiaries operate in the plastics
market in a family of products known as "reinforced plastics". Reinforced
plastics are combinations of resins and reinforcing fibers (typically glass or
carbon) that are molded to shape. The Columbus, Ohio and Gaffney, South Carolina
facilities produce reinforced plastics by compression molding sheet molding
compound ("SMC") in a closed mold process. The Matamoros, Mexico facility
produces reinforced plastic products by spray-up and hand-lay-up open mold
processes and vacuum assisted resin infused ("VRIM") closed mold process.


2. EARNINGS PER COMMON SHARE

        Basic earnings per common share is computed based on the weighted
average number of common shares outstanding during the period. Diluted earnings
per common share is computed similarly but include the effect of the exercise of
stock options under the treasury stock method. In calculating net income per
share for the three and nine months ended September 30, 2003, and September 30,
2002, stock options had no effect on the weighted average shares for the
computation of diluted income per share and consequently basic and diluted net
income per share were the same.


3. MAIN CUSTOMERS

        Core Molding Technologies currently has four major customers,
International Truck & Engine Corporation ("International"), Yamaha Motor
Corporation ("Yamaha"), Lear Corporation ("Lear"), and Freightliner, LLC
("Freightliner"). The following table presents net sales for the above-mentioned
customers for the three and nine months ended September 30, 2003 and September
30, 2002:

5. STOCK-BASED COMPENSATION

        Core Molding Technologies accounts for its stock option plans in
accordance with APB Opinion No. 25, under which no compensation cost has been
recognized. Had compensation cost for all stock option plans been determined
consistent with SFAS No. 123, "Accounting for Stock Based Compensation," Core
Molding Technologies' net income and earnings per common share would have
resulted in the amounts as reported below.

6. NEW ACCOUNTING PRONOUNCEMENTS

        In November 2002, the Financial Accounting Standards Board ("FASB")
issued FASB Interpretation ("FIN") No. 45, "Guarantor's Accounting and
Disclosure Requirements for Guarantees, Including Indirect Guarantees of
Indebtedness of Others." FIN No. 45 clarifies the requirements of Statement of
Financial Accounting Standards ("SFAS") No. 5, "Accounting for Contingencies,"
relating to the guarantor's accounting for and disclosures of certain guarantees
issued. The initial recognition and measurement provisions of the interpretation
are applicable on a prospective basis to guarantees issued or modified after
December 31, 2002, irrespective of the guarantor's fiscal year-end. The
disclosure requirements of the interpretation were effective for financial
statements of interim or annual periods ending after December 15, 2002. The
provisions of FIN 45 did not have a material impact on Core Molding
Technologies' financial condition or results of operations.

        In January 2003, the FASB issued Interpretation No. 46, "Consolidation
of Variable Interest Entities." This interpretation addresses consolidation
requirements of certain off balance sheet entities. The provisions of this
interpretation are effective for years beginning after December 15, 2003. The
provisions of FIN 46 are not expected to have a material impact on Core Molding
Technologies' financial condition or results of operations.

        In April 2003, the FASB issued SFAS No. 149, "Amendment of Statement 133
on Derivative Instruments and Hedging Activities," which amends and clarifies
accounting and reporting for certain derivative instruments. This statement is
effective for contracts entered into or modified after June 30, 2003, and for
hedging relationships designated after June 30, 2003, and is to be applied
prospectively. Core Molding Technologies has adopted SFAS No. 149 and its
adoption did not have a material impact on the consolidated financial statements
of Core Molding Technologies.

        In May 2003, the FASB issued SFAS No. 150, "Accounting for Certain
Financial Instruments with Characteristics of both Liabilities and Equity,"
which establishes standards for how an issuer classifies and measures certain
financial instruments with characteristics of both liabilities and equity. This
statement is effective for financial instruments entered into or modified after
May 31, 2003, and otherwise is effective at the beginning of the first interim
period beginning after June 15, 2003. The adoption of SFAS No. 150 did not have
a material impact on Core Molding Technologies' consolidated financial
statements.

                         PART I - FINANCIAL INFORMATION
                                     ITEM 2

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS

        This Management's Discussion and Analysis of Financial Condition and
Results of Operations contains forward-looking statements within the meaning of
the federal securities laws. As a general matter, forward-looking statements are
those focused upon future plans, objectives or performance as opposed to
historical items and include statements of anticipated events or trends and
expectations and beliefs relating to matters not historical in nature. Such
forward-looking statements involve known and unknown risks and are subject to
uncertainties and factors relating to Core Molding Technologies' operations and
business environment, all of which are difficult to predict and many of which
are beyond Core Molding Technologies' control. These uncertainties and factors
could cause Core Molding Technologies' actual results to differ materially from
those matters expressed in or implied by such forward-looking statements.

        Core Molding Technologies believes that the following factors, among
others, could affect its future performance and cause actual results to differ
materially from those expressed or implied by forward-looking statements made in
this quarterly report: business conditions in the plastics, transportation,
watercraft and commercial product industries; general economic conditions in the
markets in which Core Molding Technologies operates; dependence upon four major
customers as the primary source of Core Molding Technologies' sales revenues;
recent efforts of Core Molding Technologies to expand its customer base; failure
of Core Molding Technologies' suppliers to perform their contractual
obligations; new technologies; competitive and regulatory matters; labor
relations; the loss or inability of Core Molding Technologies to attract key
personnel; the availability of capital; the ability of Core Molding Technologies
to provide on-time delivery to customers, which may require additional shipping
expenses to ensure on-time delivery or otherwise result in late fees; risk of
cancellation or rescheduling of orders; and management's decision to pursue new
products or businesses which involve additional costs, risks or capital
expenditures.

                                    OVERVIEW

        Core Molding Technologies is a compounder of sheet molding composite
("SMC") and molder of fiberglass reinforced plastics. Core Molding Technologies
produces high quality fiberglass reinforced molded products and SMC materials
for varied markets, including medium and heavy-duty trucks, automobiles,
personal watercraft and other commercial products. The demand for Core Molding
Technologies' products is affected by economic conditions in the United States,
Canada and Mexico. Core Molding Technologies' manufacturing operations have a
significant fixed cost component. Accordingly, during periods of changing
demands, the profitability of Core Molding Technologies' operations may change
proportionately more than revenues from operations.

        On December 31, 1996, Core Molding Technologies acquired substantially
all of the assets and assumed certain liabilities of Columbus Plastics, a wholly
owned operating unit of International Truck & Engine Corporation's
("International") truck manufacturing division since its formation in late 1980.
Columbus Plastics, located in Columbus, Ohio, was a compounder and compression
molder of SMC. In 1998 Core Molding Technologies began compression molding
operations at its second facility in Gaffney, South Carolina, and in October
2001, Core Molding Technologies acquired certain assets of Airshield
Corporation. As a result of this acquisition, Core Molding Technologies expanded
its fiberglass molding capabilities to include the spray up, hand-lay-up and
vacuum assisted resin infusion molding processes in Matamoros, Mexico.


RESULTS OF OPERATIONS

THREE MONTHS ENDED SEPTEMBER 30, 2003, AS COMPARED TO THREE MONTHS ENDED
SEPTEMBER 30, 2002

        Net sales for the three months ended September 30, 2003, totaled
$19,335,000 representing an approximate 17% decrease from the $23,399,000
reported for the three months ended September 30, 2002. The primary reason for
the decrease in sales was due to a reduction in completed tooling projects and
lower product sales to truck original equipment manufacturers. Revenue from
tooling projects totaled $45,000 for the three months ended September 30, 2003.
Tooling project revenues for the three months ended September 30, 2002, totaled
$2,473,000. Tooling project revenues are sporadic in nature and do not represent
a recurring trend. Tooling project revenues


                                       10




represented the primary reason for the decrease in sales to International for
the three months ended September 30, 2003, as compared to the three months ended
September 30, 2002. Total product sales revenue, excluding tooling project
revenue, was lower by approximately 8% for the three months ended September 30,
2003, as compared to September 30, 2002. The primary reason for this decrease
was due to the negative impact general economic conditions have had on the
demand for medium and heavy-duty trucks. Sales to Yamaha increased by $706,000
for the three months ended September 30, 2003, compared to the same time period
last year. The primary reason for this increase was due to an increase in
purchases of SMC by Yamaha.

        Gross Margin was approximately 14.5% of sales for the three months ended
September 30, 2003, compared with 14.1% for the three months ended September 30,
2002. Improvements in material usage, labor efficiency and repairs and
maintenance spending were offset by increased healthcare benefits, natural gas
pricing, sales price adjustments and the impact of lower product sales volumes.
In October 2003, Core Molding Technologies incurred unplanned premium freight
expenses in order to provide on-time delivery to one of its customers. The
circumstances, which related to a secondary supply system, were temporary in
nature and have been resolved. The premium freight expenses incurred will have
an adverse effect on gross margin and earnings of approximately $0.03 per share
in the fourth quarter of 2003. Despite these circumstances, the Company
anticipates that the fourth quarter 2003 will still be profitable.

        Selling, general and administrative expenses ("SG&A") totaled $2,310,000
for the three months ended September 30, 2003, decreasing from $2,455,000 for
the three months ended September 30, 2002. The primary reasons for this decrease
were due to decreases in profit sharing accruals and real estate and property
taxes. These decreases were partially offset by increases in Core Molding
Technologies' insurance costs.

        Interest expense totaled $430,000 for the three months ended September
30, 2003, decreasing from $509,000 for the three months ended September 30,
2002. The primary reason for the decrease was due to the principal payment made
on the secured note payable due to International Truck and Engine Corporation
(see Note 6 in the 2002 Annual Report to Shareholders). Interest rates for the
industrial revenue bond were favorable; however, due to the interest rate swap,
the interest rate is essentially fixed for this debt instrument.

        Income taxes for the three months ended September 30, 2003, are
estimated to be approximately 32% of total earnings before taxes. The lower rate
is a result of a foreign tax adjustment recorded in the quarter and does not
represent a change in Core Molding Technologies' effective tax rate, which is
estimated to be 39%. Actual tax payments will be lower than the recorded
expenses as Core Molding Technologies has substantial federal tax loss
carryforwards. These loss carryforwards were recorded as a deferred tax asset.
As the tax loss carryforwards are utilized to offset federal income tax
payments, Core Molding Technologies reduces the deferred tax asset as opposed to
recording a reduction in income tax expense.

        Net income for the three months ended September 30, 2003, was $56,000,
or $.01 per basic and diluted share, representing a decrease of $429,000 as
compared to the net income for the three months ended September 30, 2002, of
$485,000, or $.05 per basic and diluted share.

NINE MONTHS ENDED SEPTEMBER 30, 2003, AS COMPARED TO NINE MONTHS ENDED SEPTEMBER
30, 2002

        Net sales for the nine months ended September 30, 2003, totaled
$70,019,000 representing an approximate 1% decrease from the $71,077,000
reported for the nine months ended September 30, 2002. Total product sales
revenue, excluding tooling project revenue, was lower by approximately 5% for
the nine months ended September 30, 2003, as compared to September 30, 2002. The
primary reason for this decrease was due to the negative impact general economic
conditions have had on the demand for medium and heavy-duty trucks. Also
contributing to the decrease were price adjustments given to certain customers.
Revenue from tooling projects totaled $10,691,000 for the nine months ended
September 30, 2003. Tooling project revenues for the nine months ended September
30, 2002, totaled $8,412,000. Tooling project revenues represented the primary
reason for the increase in sales to International. Tooling project revenues are
sporadic in nature and do not represent a recurring trend.

        Sales to customers other than the four major customers for the nine
months ended September 30, 2003, decreased approximately 39% to $6,634,000 from
$10,793,000 for the nine months ended September 30, 2002. The decrease in sales
was primarily due to revenue from completed tooling projects from other
customers being less for the nine months ended September 30, 2003, as compared
to the nine months ended September 30, 2002.

        Gross Margin was approximately 16.0% of sales for the nine months ended
September 30, 2003, compared with 15.3% for the nine months ended September 30,
2002. The increase in gross margin, as a percentage of sales


                                       11




from the prior year, was primarily due to improvements in material usage and
labor efficiency, which were largely offset by increases in employee benefit
programs, most notably healthcare costs and postretirement healthcare and higher
energy cost, specifically natural gas pricing. In October 2003, Core Molding
Technologies incurred unplanned premium freight expenses in order to provide
on-time delivery to one of its customers. The circumstances, which related to a
secondary supply system, were temporary in nature and have been resolved. The
premium freight expenses incurred will have an adverse effect on gross margin
and earnings of approximately $0.03 per share in the fourth quarter of 2003.
Despite these circumstances, the Company anticipates that the fourth quarter
2003 will still be profitable.

        Selling, general and administrative expenses ("SG&A") totaled $7,176,000
for the nine months ended September 30, 2003, increasing from $7,044,000 for the
nine months ended September 30, 2002. The primary reasons for this increase were
largely due to increases in insurance costs.

        Interest expense totaled $1,365,000 for the nine months ended September
30, 2003, decreasing from $1,518,000 for the nine months ended September 30,
2002. The primary reason for the decrease was due to the principal payment made
on the secured note payable due to International (see Note 6 in the 2002 Annual
Report to Shareholders). Interest rates for the industrial revenue bond were
favorable; however, due to the interest rate swap, the interest rate is
essentially fixed for this debt instrument.

        Income taxes for the nine months ended September 30, 2003, are estimated
to be approximately 39% of total earnings before taxes. Actual tax payments will
be lower than the recorded expenses as Core Molding Technologies has substantial
federal tax loss carryforwards. These loss carryforwards were recorded as a
deferred tax asset. As the tax loss carryforwards are utilized to offset federal
income tax payments, Core Molding Technologies reduces the deferred tax asset as
opposed to recording a reduction in income tax expense.

        Net income for the nine months ended September 30, 2003, was $1,699,000,
or $.17 per basic and diluted share, representing a decrease of $27,000 as
compared to the net income for the nine months ended September 30, 2002, of
$1,726,000, or $.18 per basic and diluted share.

LIQUIDITY AND CAPITAL RESOURCES

        Core Molding Technologies' primary cash requirements are for operating
expenses, debt service and capital expenditures. These cash requirements have
historically been met through a combination of cash flow from operations,
equipment leasing, issuance of Industrial Revenue Bonds and bank lines of
credit.

        Cash provided by operations for the nine months ended September 30,
2003, totaled $4,554,000. Net income increased operating cash flows by
$1,699,000. Non-cash deductions included depreciation and amortization of
$1,602,000, an increase of accrued interest payable of $358,000 and an increase
in the postretirement healthcare benefits liability of $990,000. The
postretirement healthcare accrual will continue to increase until retirees begin
to utilize their retirement medical benefits. A decrease in deferred income
taxes also had a positive impact on operating cash flows of $789,000, which is a
result of Core Molding Technologies' net operating loss carryforwards reducing
current year tax obligations. Partially offsetting the above mentioned increases
in operating cash flows were increases in accounts receivable of $2,504,000 and
inventories of $1,199,000.

        Investing activities decreased cash flow by $1,300,000 for the nine
months ended September 30, 2003. Capital expenditures totaled $1,304,000, which
was primarily related to the acquisition of machinery and equipment. Core
Molding Technologies anticipates spending an additional $500,000 for the
remainder of the year for capital projects.

        Financing activities reduced cash flow by $2,151,000 due to principal
repayments on the secured note payable due to International Truck and Engine of
$1,861,000 and for the regularly scheduled payment on the Industrial Revenue
Bond of $290,000.

        At September 30, 2003, Core Molding Technologies had cash on hand of
$10,079,000 and an available line of credit of $7,500,000, which is scheduled to
mature on April 30, 2004. As of September 30, 2003, Core Molding Technologies
was in compliance of all three of its financial debt covenants for the Line of
Credit and letter of credit securing the Industrial Revenue Bond and certain
equipment leases. The covenants relate to maintaining certain financial ratios.
Management expects Core Molding Technologies to meet these covenants for the
year 2003. However, if a material adverse change in the financial position of
Core Molding Technologies should occur, Core


                                       12




Molding Technologies' liquidity and ability to obtain further financing to fund
future operating and capital requirements could be negatively impacted.

        Core Molding Technologies does not have off-balance sheet arrangements,
financings, or other relationships with unconsolidated entities or other persons
that have or are reasonably likely to have a current or future material effect
on our financial condition, changes in financial condition, revenues or
expenses, results of operation, liquidity or capital expenditures.



CRITICAL ACCOUNTING POLICIES AND ESTIMATES

        Management's Discussion and Analysis of Financial Condition and Results
of Operations discusses Core Molding Technologies' consolidated financial
statements, which have been prepared in accordance with accounting principles
generally accepted in the United States. The preparation of these consolidated
financial statements requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and the disclosure of
contingent assets and liabilities at the date of the consolidated financial
statements and the reported amounts of revenues and expenses during the
reporting period. On an on-going basis, management evaluates its estimates and
judgments, including those related to accounts receivable, inventories, goodwill
and long-lived assets, post retirement benefits, and income taxes. Management
bases its estimates and judgments on historical experience and on various other
factors that are believed to be reasonable under the circumstances, the results
of which form the basis for making judgments about the carrying value of assets
and liabilities that are not readily apparent from other sources. Actual results
may differ from these estimates under different assumptions or conditions.

        Management believes the following critical accounting policies, among
others, affect its more significant judgments and estimates used in the
preparation of its consolidated financial statements.

Accounts receivable allowances:
        Management maintains allowances for doubtful accounts for estimated
losses resulting from the inability of its customers to make required payments.
If the financial condition of Core Molding Technologies' customers were to
deteriorate, resulting in an impairment of their ability to make payments,
additional allowances may be required. Core Molding Technologies had recorded an
allowance for doubtful accounts of $533,000 at September 30, 2003, and $543,000
at December 31, 2002. Management also records estimates for customer returns,
deductions and price adjustments. Should customer returns, deductions and price
adjustments fluctuate from the estimated amounts, additional allowances may be
required. Core Molding Technologies had recorded an allowance for these
chargebacks of $693,000 at September 30, 2003, and $473,000 at December 31,
2002.

Inventories:
        Management identifies slow moving or obsolete inventories and estimates
appropriate loss provisions related to these inventories. Historically, these
loss provisions have not been significant. Should actual results differ from
these estimates, additional provisions may be required. Core Molding
Technologies had recorded an allowance for slow moving and obsolete inventory of
$393,000 at September 30, 2003, and $278,000 at December 31, 2002.

Goodwill and Long-Lived Assets:
        Management evaluates whether impairment exists for goodwill and
long-lived assets. Should actual results differ from the assumptions used to
determine the implied value of goodwill, an impairment may be required. In
particular, decreases in future cash flows from operations below the assumptions
could have an adverse affect on Core Molding Technologies' operations. Core
Molding Technologies has not recorded any impairment to goodwill or long-lived
assets for the nine months ended September 30, 2003 or the year ended December
31, 2002.

Postretirement benefits:
        Management records an accrual for post retirement costs associated with
the Company sponsored health care plan for certain employees. Should actual
results differ from the assumptions used to determine the reserves, additional
provisions may be required. In particular, increases in future healthcare costs
above the assumptions could have an adverse affect on Core Molding Technologies'
operations. Core Molding Technologies had recorded a liability for post
retirement healthcare benefits based on actuarially computed estimates of
$6,952,000 at September 30, 2003, and $5,962,000 at December 31, 2002.


                                       13



Income taxes:
        Management records a valuation allowance to reduce its deferred tax
assets to the amount that it believes is more likely than not to be realized.
Core Molding Technologies has considered future taxable income in assessing the
need for the valuation allowance and recorded a valuation allowance (see Note 10
in the 2002 Annual Report to Shareholders). The valuation reserve will be
adjusted as the Company determines the actual amount of deferred tax assets that
will be realized. Core Molding Technologies had recorded a valuation allowance
of $1,425,000 at September 30, 2003 and December 31, 2002.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

        Core Molding Technologies' primary market risk results from fluctuations
in interest rates. Core Molding Technologies is also exposed to changes in the
price of commodities used in its manufacturing operations and foreign currency
fluctuations associated with the Mexican peso. The Company does not hold any
material market risk sensitive instruments for trading purposes.

        Core Molding Technologies has the following three items that are
sensitive to market risks: (1) Industrial Revenue Bond ("IRB") with a variable
interest rate. Core Molding Technologies has an interest rate swap to fix the
interest rate at 4.89%; (2) Revolving line of credit, which bears a variable
interest rate; and (3) Foreign currency purchases in which Core Molding
Technologies purchases Mexican pesos with United States dollars to meet certain
obligations that arise due to the facility located in Mexico.

        Assuming a hypothetical 20% change in short-term interest rates in both
the nine month periods ended September 30, 2003, and 2002, interest expense
would not change significantly, as the interest rate swap agreement would
generally offset the impact, and Core Molding Technologies has no borrowings
under the revolving line of credit.

CONTROLS AND PROCEDURES

        As of the end of the period covered by this Quarterly Report on Form
10-Q Core Molding Technologies carried out an evaluation, under the supervision
and with the participation of Core Molding Technologies' management, including
Core Molding Technologies' Chief Executive Officer and Chief Financial Officer,
of the effectiveness of the design and operation of Core Molding Technologies'
disclosure controls and procedures (as defined in Rules 13a-15(e) and
15(d)-15(e) of the Securities Exchange Act of 1934, (as amended the "Exchange
Act")). Based upon that evaluation, the Chief Executive Officer and Chief
Financial Officer concluded that Core Molding Technologies' disclosure controls
and procedures are effective in timely alerting them to material information
required to be included in this Quarterly Report on Form 10-Q. There have been
no significant changes in Core Molding Technologies' internal controls or in
other factors, which could significantly affect internal controls subsequent to
the date Core Molding Technologies carried out its evaluation.

        No changes were made to Core Molding Technologies' system of internal
controls over financial reporting (as such term is defined in Rules 13a-15(f)
and 15d-15(f) of the Exchange Act) during the most recent fiscal quarter that
has materially affected, or is reasonably likely to materially affect, Core
Molding Technologies' internal control over financial reporting.
