Notes to Consolidated Financial Statements

(Unaudited)

1. BASIS OF PRESENTATION

The accompanying unaudited consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q 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” or the “Company”) at March 31, 2024, and the results of operations and cash flows for the three months ended March 31, 2024. The “Notes to Consolidated Financial Statements” contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2023, should be read in conjunction with these consolidated financial statements.

Core Molding Technologies and its subsidiaries operate in the engineered materials market as one operating segment as a molder of thermoplastic and thermoset structural products. The Company produces and sells molded products for varied markets, including medium and heavy-duty trucks, power sports, building products, industrial and utilities and other commercial markets. Core Molding Technologies has its headquarters in Columbus, Ohio, and operates six production facilities in the United States, Canada and Mexico.

2. CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Principles of Consolidation: 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.

Use of Estimates: The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities, and reported amounts of revenues and expenses during the reporting period. On an on-going basis, management evaluates its estimates and judgments. 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 and conditions.

Revenue Recognition: The Company historically has recognized revenue from two streams, product revenue and tooling revenue. Product revenue is earned from the manufacture and sale of sheet molding compounds and thermoset and thermoplastic products. Revenue from product sales is generally recognized when products are shipped, as the Company transfers control to the customer and is entitled to payment upon shipment. In certain circumstances, the Company recognizes revenue from product sales when products are produced and the customer takes control at our production facility.

Tooling revenue is earned from manufacturing multiple tools, molds and assembly equipment as part of a tooling program for a customer. Given that the Company is providing a significant service of producing highly interdependent component parts of the tooling program, each tooling program consists of a single performance obligation to provide the customer the capability to produce a single product. Based on the arrangement with the customer, the Company recognizes revenue either at a point in time or over a given period. When the Company does not have an enforceable right to payment, the Company recognizes tooling revenue at a point in time. In such cases, the Company recognizes revenue upon customer acceptance, which is when the customer has legal title to the tools.

Certain tooling programs include an enforceable right to payment. In those cases, the Company recognizes revenue over time based on the extent of progress towards completion of its performance obligation. The Company uses a cost-to-cost measure of progress for such contracts because it best depicts the transfer of value to the customer and also correlates with the amount of consideration to which the entity expects to be titled in exchange for transferring the promised goods or services to the customer. Under the cost-to-cost measure of progress, progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. Revenues are recorded proportionally as costs are incurred.

Cash and Cash Equivalents: The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Cash is held primarily in three banks in three separate jurisdictions. The Company had $26,618,000 cash on hand at March 31, 2024 and had $24,104,000 cash on hand at December 31, 2023.

8

Accounts Receivable Allowances: Management maintains allowances for credit losses resulting from the inability of its customers to make required payments. If the financial condition of the Company’s customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required. The Company has determined that a $90,000 allowance for credit losses is needed at March 31, 2024 and none is needed at December 31, 2023. Management also records estimates for customer returns and deductions, discounts offered to customers, and for price adjustments. Should customer returns and deductions, discounts, and price adjustments fluctuate from the estimated amounts, additional allowances may be required. The Company had an allowance for estimated chargebacks of $123,000 at March 31, 2024 and $138,000 at December 31, 2023. There have been no material changes in the methodology of these calculations.

Inventories: Inventories, which include material, labor and manufacturing overhead, are valued at the lower of cost or net realizable value. The inventories are accounted for using the first-in, first-out (FIFO) method of determining inventory costs. Inventory quantities on-hand are regularly reviewed, and where necessary, provisions for excess and obsolete inventory are recorded based on historical and anticipated usage. The Company has recorded an allowance for slow moving and obsolete inventory of $730,000 at March 31, 2024 and $671,000 at December 31, 2023.

Contract Assets/Liabilities: Contract assets and liabilities represent the net cumulative customer billings, vendor payments and revenue recognized for tooling programs. For tooling programs where net revenue recognized and vendor payments exceed customer billings, the Company recognizes a contract asset. For tooling programs where net customer billings exceed revenue recognized and vendor payments, the Company recognizes a contract liability. Customer payment terms vary by contract and can range from progress payments based on work performed or one single payment once the contract is completed. The Company has recorded contract assets of $80,000 at March 31, 2024, and $77,000 at December 31, 2023. Contract assets are generally classified as current within prepaid expenses and other current assets on the Consolidated Balance Sheets. For the three months ended March 31, 2024 and March 31, 2023 the Company recognized no impairments on contract assets. For the three months ended March 31, 2024, the Company recognized $1,841,000 of revenue from contract liabilities related to open jobs outstanding as of December 31, 2023.

Income Taxes: The Company evaluates the balance of deferred tax assets that will be realized based on the premise that the Company is more-likely-than-not to realize deferred tax benefits through the generation of future taxable income.

Long-Lived Assets: Long-lived assets consist primarily of property, plant and equipment and definite-lived intangibles. The recoverability of long-lived assets is evaluated by an analysis of operating results and consideration of other significant events or changes in the business environment. The Company evaluates whether impairment exists for property, plant and equipment on the basis of undiscounted expected future cash flows from operations before interest. There were no impairment charges of the Company’s long-lived assets for the three months ended March 31, 2024 and March 31, 2023, respectively.

Goodwill: The purchase consideration of acquired businesses has been allocated to the assets and liabilities acquired based on the estimated fair values on the respective acquisition dates. Based on these values, the excess purchase consideration over the fair value of the net assets acquired was allocated to goodwill. The Company accounts for goodwill in accordance with FASB ASC Topic 350, Intangibles - Goodwill and Other. FASB ASC Topic 350 prohibits the amortization of goodwill and requires these assets be reviewed for impairment.

The annual impairment tests of goodwill may be completed through qualitative assessments; however, the Company may elect to bypass the qualitative assessment and proceed directly to a quantitative impairment test for any period. The Company may resume the qualitative assessment in any subsequent period.

Under a qualitative and quantitative approach, the impairment test for goodwill consists of an assessment of whether it is more-likely-than-not that the fair value is less than its carrying amount. As part of the qualitative assessment, the Company considers relevant events and circumstances that affect the fair value or carrying amount of the Company. Such events and circumstances could include changes in economic conditions, industry and market conditions, cost factors, overall financial performance, and capital markets pricing. The Company places more weight on the events and circumstances that most affect the Company's fair value or carrying amount. These factors are all considered by management in reaching its conclusion about whether to perform step one of the impairment test. If the Company elects to bypass the qualitative assessment, or if a qualitative assessment indicates it is more-likely-than-not that the estimated carrying value exceeds its fair value, the Company proceeds to a quantitative approach. There were no impairment charges of the Company's goodwill for the three months ended March 31, 2024 and March 31, 2023, respectively.

Self-Insurance: The Company is self-insured with respect to its facilities in Columbus, Ohio; Gaffney, South Carolina; Winona, Minnesota; and Brownsville, Texas for medical, dental and vision claims and Columbus, Ohio for workers’ compensation claims, all of which are subject to stop-loss insurance thresholds. The Company is also self-insured for dental and

9

vision with respect to its Cobourg, Canada location. The Company has recorded an estimated liability for self-insured medical, dental and vision claims incurred but not reported and worker’s compensation claims incurred but not reported at March 31, 2024 and December 31, 2023 of $997,000 and $988,000, respectively. Estimated liabilities for self-insurance are classified as current within accrued other liabilities on the Consolidated Balance Sheets.

Post-Retirement Benefits: Management records an accrual for post-retirement costs associated with the health care plan sponsored by Core Molding Technologies. 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 effect on Core Molding Technologies’ operations. The effect of a change in healthcare costs is described in Note 12, "Post Retirement Benefits", of the Notes to Consolidated Financial Statements contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2023. Core Molding Technologies had a liability for post-retirement healthcare benefits based on actuarial computed estimates of $3,008,000 at March 31, 2024 and $3,116,000 at December 31, 2023.

3. NET INCOME PER COMMON SHARE

Net income per common share is computed based on the weighted average number of common shares outstanding during the period. Diluted net income per common share is computed similarly but includes the effect of the assumed exercise of dilutive stock appreciation rights and restricted stock under the treasury stock method.

On May 13, 2021, the Company's stockholders approved the 2021 Long Term Equity Incentive Plan (the “2021 Plan”) that replaced the 2006 Long Term Equity Incentive Plan (the “2006 Plan”) approved in May 2006 and amended in May 2015. The 2021 Plan provides restricted stock award recipients voting rights equivalent to the Company's common stock and accrual of dividends but not receipt of dividends until all conditions or restrictions related to such award have been satisfied. Accordingly, the restricted shares are not considered participating shares. The 2006 Plan provides restricted stock award recipients voting rights equivalent to the Company’s common stock and accrual and receipt of dividends irrespective of any conditions or restrictions related to such award being satisfied. Accordingly, the restricted shares granted from the 2006 Plan are considered a participating security and the Company is required to apply the two-class method to consider the impact of the restricted shares on the calculation of basic and diluted earnings per share.

The computation of basic and diluted net income per common share (in thousands, except for per share data) is as follows:

	Three months ended March 31,
	2024		2023
Net income	$	3,759	$	5,852
Less: net income allocated to participating securities	—		54
Net income available to common stockholders	$	3,759	$	5,798
Weighted average common shares outstanding — basic	8,666,000		8,418,000
Effect of weighted average dilutive securities	166,000		334,000
Weighted average common and potentially issuable common shares outstanding — diluted	8,832,000		8,752,000
Basic net income per common share	$	0.43	$	0.69
Diluted net income per common share	$	0.43	$	0.66

The computation of basic and diluted net income per participating share is as follows (in thousands, except for per share data):

	Three months ended March 31,
	2024		2023
Net income allocated to participating securities	$	—	$	54

Operating leases are included in operating lease right-of-use ("ROU") assets, accrued other liabilities and other non-current liabilities in the Consolidated Balance Sheets. ROU assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease.

The Company used the applicable incremental borrowing rate at implementation date to measure lease liabilities and ROU assets. The incremental borrowing rate used by the Company was based on baseline rates and adjusted by the credit spreads commensurate with the Company’s secured borrowing rate. At each reporting period when there is a new lease initiated, the Company will utilize its incremental borrowing rate to perform lease classification tests on lease components and to measure ROU assets and lease liabilities.

The components of lease expense were as follows (in thousands):

	Three months ended March 31,
	2024		2023
Operating lease cost	$	538	$	427

Huntington Credit Agreement

On July 22, 2022, the Company entered into a credit agreement (the “Huntington Credit Agreement”) with The Huntington National Bank (“Huntington”), as the sole lender, administrative agent, lead arranger and book runner, and the lenders from time to time thereto. Pursuant to the terms of the Huntington Credit Agreement, Huntington made available to the Company secured loans (the “Huntington Loans”) in the maximum aggregate principal amount of $75,000,000, comprised of three $25,000,000 commitments: a term loan commitment, a CapEx loan commitment and a revolving loan commitment.

At the option of the Company, the Huntington Loans shall be comprised of Alternative Base Rate (ABR) Loans or Secure Overnight Financing Rate (SOFR) Loans.

ABR Loans bear interest at a per annum rate equal to ABR plus a margin of 280 to 330 basis points determined based on the Company’s leverage ratio. ABR is the greatest of (a) the Prime Rate in effect on such day, (b) the Federal Funds Rate in effect on such day plus 0.50% per annum and (c) Daily Simple SOFR for such day (taking into account any floor set forth in the definition of “Daily Simple SOFR”) plus 1.00% per annum; provided, that if the ABR shall be less than 0.00%, then ABR shall be deemed to be 0.00%.

SOFR Loans bear interest at a per annum rate equal to Daily Simple SOFR plus a margin of 180 to 230 basis points determined based on the Company’s leverage ratio. Daily Simple SOFR means, for any day (a “SOFR Rate Day”), a rate per annum equal to the greater of (a) SOFR for the day (such day, the “SOFR Determination Date”) that is five (5) U.S. Government Securities

14

Business Days prior to (i) if such SOFR Rate Day is a U.S. Government Securities Business Day, such SOFR Rate Day or (ii) if such SOFR Rate Day is not a U.S. Government Securities Business Day, the U.S. Government Securities Business Day immediately preceding such SOFR Rate Day, in each case, as such SOFR is published by the SOFR Administrator on the SOFR Administrator’s Website, and (b) 0.00%.

The Company’s obligations under the Huntington Credit Agreement are secured by all of the U.S. and Canadian assets of the Company, including all of its equity interests in each of the Company’s U.S. and Canadian subsidiaries and 65% of the Company’s equity interest in its Mexican subsidiaries, and are unconditionally guaranteed by certain subsidiaries of the Company.

The Huntington Credit Agreement contains certain customary representations and warranties, conditions, affirmative and negative covenants and events of default. The Company is in compliance with such covenants as of March 31, 2024.

Voluntary prepayments of amounts outstanding under the Huntington Loans are permitted at any time without premium or penalty.

The Company incurred debt origination fees of $402,000 related to the Huntington Credit Agreement, which is being amortized over the life of the agreement.

Huntington Capex Loan

Pursuant to the terms of the Huntington Credit Agreement, Huntington made available to the Company secured Capex loan (the “Huntington Capex Loan”) in the maximum aggregate principal amount of $25,000,000. Proceeds of the Huntington Capex Loan will be used to finance the ongoing capital expenditure needs of the Company.

Any borrowings from the Huntington Capex Loan will be converted to new term loans annually each February, beginning February 2025, and will have monthly principal repayments based on a sixty-month amortization period with all amounts outstanding on the Huntington Capex Loan being fully due on July 22, 2027.

Huntington Revolving Loan

Pursuant to the terms of the Huntington Credit Agreement, Huntington made available to the Company a revolving loan commitment (the “Huntington Revolving Loan”) of $25,000,000. The Company has $25,000,000 of available revolving loans of which none was outstanding as of March 31, 2024 and December 31, 2023, respectively.

The Huntington Credit Agreement makes available to the Company a revolving commitment in the maximum amount of $25,000,000 at the Company’s option at any time during the five-year period following the closing. The revolving loan commitment terminates, and all outstanding borrowings thereunder must be repaid on July 22, 2027.

The interest rate for the Huntington Revolving Loan was 7.11% and 7.11% as of March 31, 2024 and December 31, 2023, respectively.

Huntington Term Loan

Pursuant to the terms of the Huntington Credit Agreement, Huntington made available to the Company a Term Loan commitment (the “Huntington Term Loan”) of $25,000,000 ($25,000,000 of which was advanced to the Company on July 22, 2022). The Huntington Term Loan is to be repaid in monthly installments beginning August 2022 of $104,000 per month for the first 24 months, $156,000 per month for the next 24 months, $208,000 for the next 12 months and the remaining balance to be paid on July 22, 2027. The interest rate for the Huntington Term Loan was 7.11% and 7.11% as of March 31, 2024 and December 31, 2023, respectively.

Interest Rate Swap Agreement

The Company entered into an interest rate swap agreement that became effective July 22, 2022 and continues through July 2027, which was designed as a cash flow hedge for $25,000,000 of the Huntington Term Loan. Under this agreement, the Company will pay a fixed rate of 2.95% to the swap counterparty in exchange for the Term Loans daily variable SOFR. As a result the interest rate paid on the Huntington Term Loan was 4.75% as of March 31, 2024 and December 31, 2023. The fair value of the interest rate swap was an asset of $797,000 and $524,000 at March 31, 2024 and December 31, 2023, respectively.

Leaf Capital Funding

On April 24, 2020 the Company entered into a finance agreement with Leaf Capital Funding of $175,000 for equipment. The parties agreed to a fixed interest rate of 5.50% and a term of 60 months.

11. INCOME TAXES

The Company evaluates the balance of deferred tax assets that will be realized based on the premise that the Company is more-likely-than-not to realize deferred tax benefits through the generation of future taxable income. Management makes assumptions, judgments, and estimates to determine the deferred tax assets and liabilities. The Company evaluates provisions and deferred tax assets quarterly to determine if adjustments to our valuation allowance are required based on the consideration of all available evidence.

At March 31, 2024, the Company had a net deferred tax asset of $1,595,000 related to tax positions in Mexico and deferred tax liabilities of $1,182,000 and $43,000 related to tax positions in the United States and Canada. Deferred tax assets are included in "Other non-current assets" on the Consolidated Balance Sheets and deferred tax liabilities are included in "Other non-current liabilities" on the Consolidated Balance Sheets. As of March 31, 2024, the Company had a valuation allowance of $1,530,000, against the deferred tax asset related to local tax positions in the Unites States, due to cumulative losses over the last three years and uncertainty related to the Company's ability to realize the deferred assets. The Company believes that the deferred tax assets associated with the Canadian, Mexican, and federal United States tax jurisdictions are more-likely-than-not to be realizable based on estimates of future taxable income.

Income tax expense for the three months ended March 31, 2024 is estimated to be $1,029,000, approximately 21.5% of income before income taxes. Income tax expense for the three months ended March 31, 2023 was estimated to be $1,919,000, approximately 24.7% of income before income taxes.

The Company files income tax returns in the United States, Mexico, Canada and various state and local jurisdictions. The Company is subject to federal income tax examinations for tax years 2014 through 2017 but the scope of examination is limited to adjustments resulting from Net Operating Loss carry back claims from the 2019, and 2020 tax years. The Company is subject to federal income tax examinations for years 2020 through 2023 with unlimited scope. The Company is not subject to state examinations for years before 2020. The Company is not subject to Mexican income tax examinations by Mexican authorities for the years before 2018 and is not subject to Canadian income tax examinations by Canadian authorities for the years before 2019.

12. STOCK BASED COMPENSATION

On May 13, 2021, The Company's stockholders approved the 2021 Long Term Equity Incentive Plan (the “2021 Plan”) that replaced the 2006 Long Term Equity Incentive Plan (the “2006 Plan”) approved in May 2006 and amended in May 2015. The 2021 Plan allows for grants to employees, officers, non-employee directors, consultants, independent contractors and advisors of non-qualified stock options, incentive stock options, stock appreciation rights, restricted stock, restricted stock units, and other stock-based awards (“stock awards”) up to an aggregate of 152,501 awards. Awards can be granted under the 2021 Plan through the earlier of May 13, 2031, or the date the maximum number of available awards under the 2021 Plan have been granted. No new awards may be granted from the 2006 Plan.

Awards under the 2021 Plan vest over one to three years and shares previously awarded and currently unvested under the 2006 Plan vest over three years. Shares granted under both the 2006 and 2021 Plans vest immediately upon the date of a participant’s death, disability or change in control.

The Company follows the provisions of FASB ASC 718 requiring that compensation cost relating to share-based payment transactions be recognized in the financial statements. The cost is measured at the grant date, based on the calculated fair value of the award, and is recognized as an expense over the employee's requisite service period (generally the vesting period of the equity award).

Restricted Stock

The Company grants shares of its common stock to certain directors, officers, key managers and employees in the form of unvested stock and units (“Restricted Stock”). These awards are measured at the fair value of the Company's common stock on the date of issuance and recognized ratably as compensation expense over the applicable vesting period, which is typically three years. The Company adjusts compensation expense for actual forfeitures, as they occur.

16

The following summarizes the status of Restricted Stock and changes during the three months ended March 31, 2024:

	Number of Shares	Weighted Average Grant Date Fair Value
Unvested balance at December 31, 2023	373,583	$	12.81
Granted	94,704	19.18
Vested	(61,508)	15.98
Forfeited	—	—
Unvested balance at March 31, 2024	406,779	$	14.31

At March 31, 2024 and 2023, there was $4,113,000 and $5,702,000, respectively, of total unrecognized compensation expense, related to Restricted Stock grants. The unrecognized compensation expense at March 31, 2024 is expected to be recognized over the weighted-average period of 2.3 years. Total compensation cost related to Restricted Stock grants for the three months ended March 31, 2024 and 2023 was $711,000 and $725,000, respectively, all of which was recorded to selling, general and administrative expense.

During the three months ended March 31, 2024 , employees withheld 17,773 shares of the Company's common stock to satisfy income tax withholding obligations in connection with the vesting of restricted awards, and in March 31, 2023 no shares of the Company's common stock was withheld. During the three months ended March 31, 2023, employees withheld 1,318 shares of common stock to satisfy income tax withholding obligations in connection with the exercise of stock appreciation rights.

Performance Restricted Stock Awards

The Company grants shares of its common stock to certain officers and key managers in the form of shares of performance-based restricted stock ("Performance Restricted Stock Awards"). These awards are measured at the fair value of the Company's common stock on the date of issuance and recognized ratably as compensation expense over the applicable vesting period to the extent that the performance measures have been satisfied as of the last day of the performance period of the award. The total amount payable as of the award's vesting date is determined by the three year average Operational Income and Return on Capital Employed performance measure achievement. The Company adjusts compensation expense for actual forfeitures as they occur, and for estimated performance measure achievement.

The following summarizes the status of Performance Restricted Stock Awards and changes during the three months ended March 31, 2024:

	Number of Shares	Weighted Average Grant Date Fair Value
Unvested balance at December 31, 2023	11,737	$	15.98
Granted	28,483	19.18
Vested	—	—
Forfeited	—	—
Unvested balance at March 31, 2024	40,220	$	18.24

At March 31, 2024 and 2023, there was $651,000 and $207,000 of total unrecognized compensation expense related to Performance Restricted Stock Awards. The unrecognized compensation expense at March 31, 2024 is expected to be recognized over the weighted-average period of 2.6 years. Total compensation cost related to Performance Restricted Stock Awards for the three months ended March 31, 2024 and March 31, 2023 was $28,000 and 6,000, all of which was recorded to selling, general and administrative expense.

13. FAIR VALUE OF FINANCIAL INSTRUMENTS

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in a transaction between market participants as of the measurement date. Fair value is measured using the fair value hierarchy and related valuation methodologies as defined in the authoritative literature. This hierarchical valuation methodology provides a fair value framework that describes the categorization of assets and liabilities in three levels based upon the assumptions (inputs) used to price the assets or liabilities. Level 1 provides the most reliable measure of fair value, whereas Level 3 generally requires significant management judgment.

The three levels are defined as follows:

Level 1 - Quoted prices in active markets for identical assets and liabilities.

Level 2 - Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-derived valuations, in which all significant inputs are observable in active markets.

Level 3 -Significant unobservable inputs reflecting management's own assumptions about the inputs used in pricing the asset or liability.

The Company’s financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable, debt, interest rate swaps and foreign currency derivatives. Cash and cash equivalents, accounts receivable and accounts payable carrying values as of March 31, 2024 and December 31, 2023 approximate fair value due to the short-term maturities of these financial instruments. As of March 31, 2024 and December 31, 2023, the carrying amounts of the Huntington Term Loan and Huntington Revolving Loan approximated fair value due to the short-term nature of the underlying variable rate SOFR used to determine interest charged on the loans. The Company had Level 2 fair value measurements at March 31, 2024 relating to the Company’s interest rate swaps and foreign currency derivatives.

Derivative and hedging activities

Foreign Currency Derivatives

The Company conducted business in foreign countries and paid certain expenses in foreign currencies; therefore, the Company was exposed to foreign currency exchange risk between the U.S. Dollar and foreign currencies, which could impact the Company’s operating income and cash flows. To mitigate risk associated with foreign currency exchange, the Company entered into forward contracts to exchange a fixed amount of U.S. Dollars for a fixed amount of foreign currency, which will be used to fund future foreign currency cash flows. At inception, all forward contracts are formally documented as cash flow hedges and are measured at fair value each reporting period.

Derivatives are formally assessed both at inception and at least quarterly thereafter, to ensure that derivatives used in hedging transactions are highly effective in offsetting changes in cash flows of the hedged item. If it is determined that a derivative ceases to be a highly effective hedge, or if the anticipated transaction is no longer probable of occurring, hedge accounting is discontinued, and any future mark-to-market adjustments are recognized in earnings. The effective portion of gain or loss is reported in other comprehensive income and the ineffective portion is reported in earnings. The impacts of these contracts were largely offset by gains and losses resulting from the impact of changes in exchange rates on transactions denominated in the foreign currency. As of March 31, 2024, the Company had no ineffective portion related to the cash flow hedges. The notional contract value of foreign currency derivatives was $5,063,000 and $28,592,000 as of March 31, 2024 and 2023, respectively.

Interest Rate Swap

The Company entered into an interest rate swap contract to fix the interest rate on an initial aggregate amount of $25,000,000 thereby reducing exposure to interest rate changes. The interest rate swap pays a fixed rate of 2.95% to the swap counterparty in exchange for daily SOFR. At inception, all interest rate swaps were formally documented as cash flow hedges and are measured at fair value each reporting period. See Note 10, "Debt", for additional information. The notional contract value of the interest rate swap was $22,917,000 and $24,167,000 as of March 31, 2024 and 2023, respectively.

Description of the Company

Core Molding Technologies and its subsidiaries operate in the engineered materials market as one operating segment as a molder of thermoplastic and thermoset structural products. The Company produces and sells molded products for varied markets, including medium and heavy-duty trucks, power sports, building products, industrial and utilities and other commercial markets. Core Molding Technologies has its headquarters in Columbus, Ohio, and operates six production facilities in the United States, Canada and Mexico.

Business Overview

General

The Company’s business and operating results are directly affected by changes in overall customer demand, operational costs and performance and leverage of our fixed cost and selling, general and administrative ("SG&A") infrastructure.

Product sales fluctuate in response to several factors, including many that are beyond the Company’s control, such as general economic conditions, interest rates, government regulations, consumer spending, raw material cost inflation, labor availability, and our customers’ production rates and inventory levels. The Company's customers operate in many different markets with different cyclicality and seasonality.

Operating performance is dependent on the Company’s ability to manage changes in input costs for items such as raw materials, labor, and overhead operating costs. The Company has certain contractual commitments that restrict its ability to pass through changes in input costs to certain customers. As a result, during periods of significant increases or decreases in input costs operating results may be impacted.

Performance is also affected by manufacturing efficiencies, including items such as on time delivery, quality, scrap, and productivity. Market factors of supply and demand can impact operating costs. In periods of rapid increases or decreases in customer demand, the Company is required to ramp operational activity up or down quickly, which may impact manufacturing efficiencies more than in periods of steady demand.

Operating performance is also dependent on the Company’s ability to effectively launch new customer programs, which are extremely complex in nature. The start of production of a new program is the result of a process of developing new molds and assembly equipment, validation testing, manufacturing process design, development and testing, along with training and often hiring employees. Meeting the targeted levels of manufacturing efficiency for new programs usually occurs over time as the Company gains experience with new tools and processes. Therefore, during a new program launch period, start-up costs and inefficiencies can affect operating results.

Business Outlook

Looking forward, based on industry analyst projections, customer forecasts, anticipated price changes, as well as anticipated new program launches, offset by current programs that we expect to begin to ramp down in the second half of 2024 as further described below, the Company expects revenues for calendar year 2024 to decrease by approximately 10 to 15 percent as compared to 2023. Additional factors contributing to our anticipated 2024 revenue outlook include an expected cyclical demand slowdown, decreased customer inventory builds due to stabilizing inventory levels as well as a consumer demand environment that is more consistent with pre-pandemic levels. The Company anticipates the revenue decrease to be more significant in the first half of 2024 and a lesser decrease in the second half of 2024 compared to the same periods in 2023.

22

Beginning in the second half of 2024 and continuing through 2026, the Company’s business with Volvo will begin transitioning from existing programs that the Company currently supplies to new programs that the Company does not support. Notwithstanding this transition and the completion of existing programs with Volvo, the Company continues to actively bid for new Volvo business, which we believe we will continue to secure outside of the current programs. Going forward we remain focused on continuing to replace phased out business from existing programs with new programs from Volvo or other customers.

The Company’s raw material supply chains remain stable, and the Company anticipates raw material pricing in 2024 to remain flat or slightly higher as compared to 2023. Labor markets have also stabilized, although at higher cost levels over the past several years. The Company does not anticipate challenges in hiring hourly labor, although management believes wage pressure will continue, especially in Mexico.

Results of Operations

Three Months Ended March 31, 2024, as Compared to Three Months Ended March 31, 2023

Net sales for the three months ended March 31, 2024 and 2023 totaled $78,145,000 and $99,507,000, respectively. Included in net sales were tooling project sales of $2,314,000 and $1,170,000 for the three months ended March 31, 2024 and 2023, respectively. Tooling sales are sporadic in nature and fluctuate in regard to scope and related revenue on a period-to-period basis. Product sales, excluding tooling project sales, for the three months ended March 31, 2024 were $75,831,000 compared to $98,337,000 for the same period in 2023. The decrease in sales is primarily the result of lower demand across all industries. The Company's product sales for the three months ended March 31, 2024 compared to the same period in 2023 by market are as follows (in thousands):

	Three months ended March 31,
	2024		2023
Medium and heavy-duty truck	$	41,509	$	49,516
Power sports	18,859		22,036
Building products	6,545		11,787
Industrial and utilities	3,346		6,430
All other	5,572		8,568
Net product revenue	$	75,831	$	98,337

Gross margin was 17.0% and 17.8% of sales for the three months ended March 31, 2024 and 2023, respectively. Gross margin compared to last year was impacted by increased net changes in selling price and raw material costs of 1.7%, offset by lower fixed cost leverage of 1.7% and operational inefficiencies and product mix of 0.8%.

Selling general and administrative expense ("SG&A") was $8,573,000 for the three months ended March 31, 2024, compared to $9,668,000 for the three months ended March 31, 2023. Decreased SG&A expenses resulted primarily from lower bonus of $512,000, favorable foreign currency translation of $210,000 and lower labor and benefits costs of $117,000 .

Net interest expense totaled $82,000 for the three months ended March 31, 2024, compared to $356,000 for the three months ended March 31, 2023. Lower interest expense was primarily due to higher interest income from cash accumulation of $252,000.

Income tax expense for the three months ended March 31, 2024 is estimated to be $1,029,000, approximately 21.5% of income before income taxes. Income tax expense for the three months ended March 31, 2023 was estimated to be $1,919,000, approximately 24.7% of income before income taxes.

The Company recorded net income for the three months ended March 31, 2024 of $3,759,000 or $0.43 per basic and diluted share compared with net income of $5,852,000, or $0.69 per basic and $0.66 diluted share, for the three months ended March 31, 2023.

23

Comprehensive income totaled $3,465,000 for the three months ended March 31, 2024, compared to comprehensive income of $5,900,000 for the same period ended March 31, 2023. The decrease was primarily related to the decrease in net income of $2,093,000.

Liquidity and Capital Resources

Historically, the Company’s primary sources of funds have been cash generated from operating activities and borrowings from third parties. Primary cash requirements are for operating expenses, capital expenditures, repayments of debt, and acquisitions. The Company from time to time will enter into foreign exchange contracts and interest rate swaps to mitigate risk of foreign exchange and interest rate volatility. As of March 31, 2024, the Company had outstanding foreign exchange contracts with notional amounts totaling $5,063,000. As of March 31, 2024, the Company had outstanding interest rate swaps with notional amounts totaling $22,917,000.

Cash provided by operating activities for the three months ended March 31, 2024 totaled $5,072,000. Net income of $3,759,000 positively impacted operating cash flows. Non-cash deductions of depreciation and amortization, and share-based compensation included in net income amounted to $3,292,000 and $739,000, respectively. Increased working capital decreased cash provided by operating activities by $2,504,000. Higher working capital was primarily related to changes in accrued liabilities and inventory offset by changes in in prepaid assets, accounts receivable and accounts payable.

Cash used in investing activities for the three months ended March 31, 2024 was $1,893,000, which related to purchases of property, plant and equipment. The Company anticipates spending approximately $13,000,000 during 2024 on property, plant and equipment purchases for all of the Company's operations. At March 31, 2024, purchase commitments for capital expenditures in progress were $2,939,000. The Company anticipates using cash from operations, its available revolving line of credit or its capex line to fund capital investments.

Cash used for financing activities for the three months ended March 31, 2024 totaled $665,000, which consisted of the purchase of treasury stock of $343,000 in exchange for payment of taxes related to net shares settlements of equity awards and repayments of long-term debt of $322,000.

At March 31, 2024, the Company had $26,618,000 cash on hand, a $25,000,000 revolving loan facility of which none is outstanding, and a $25,000,000 Capex loan facility with no outstanding balance.

The Company is required to meet certain financial covenants included in the Huntington Credit Agreement (defined below), which covenants include a net debt leverage and a fixed charge coverage ratio. As of March 31, 2024, the Company was in compliance with its financial covenants associated with the loans made under the Huntington Credit Agreement as described below.

Management believes cash on hand, cash flow from operating activities and available borrowings under the Company's credit agreement will be sufficient to meet the Company's current liquidity needs.

Huntington Credit Agreement

On July 22, 2022, the Company entered into a credit agreement (the “Huntington Credit Agreement”) with The Huntington National Bank (“Huntington”), as the sole lender, administrative agent, lead arranger and book runner, and the lenders from time to time thereto. Pursuant to the terms of the Huntington Credit Agreement, Huntington made available to the Company secured loans (the “Huntington Loans”) in the maximum aggregate principal amount of $75,000,000, comprised of three $25,000,000 commitments: a term loan commitment, a CapEx loan commitment and a revolving loan commitment.

At the option of the Company, the Huntington Loans shall be comprised of Alternative Base Rate (ABR) Loans or Secure Overnight Financing Rate (SOFR) Loans.

ABR Loans bear interest at a per annum rate equal to ABR plus a margin of 280 to 330 basis points determined based on the Company’s leverage ratio. ABR is the greatest of (a) the Prime Rate in effect on such day, (b) the Federal Funds Rate in effect on such day plus 0.50% per annum and (c) Daily Simple SOFR for such day (taking into account any floor set forth in the definition of “Daily Simple SOFR”) plus 1.00% per annum; provided, that if the ABR shall be less than 0.00%, then ABR shall be deemed to be 0.00%.

SOFR Loans bear interest at a per annum rate equal to Daily Simple SOFR plus a margin of 180 to 230 basis points determined based on the Company’s leverage ratio. Daily Simple SOFR means, for any day (a “SOFR Rate Day”), a rate per annum equal to the greater of (a) SOFR for the day (such day, the “SOFR Determination Date”) that is five (5) U.S. Government Securities Business Days prior to (i) if such SOFR Rate Day is a U.S. Government Securities Business Day, such SOFR Rate Day or (ii) if

24

such SOFR Rate Day is not a U.S. Government Securities Business Day, the U.S. Government Securities Business Day immediately preceding such SOFR Rate Day, in each case, as such SOFR is published by the SOFR Administrator on the SOFR Administrator’s Website, and (b) 0.00%.

The Company’s obligations under the Huntington Credit Agreement are secured by all of the U.S. and Canadian assets of the Company, including all of its equity interests in each of the Company’s U.S. and Canadian subsidiaries and 65% of the Company’s equity interest in its Mexican subsidiaries, and are unconditionally guaranteed by certain subsidiaries of the Company.

The Huntington Credit Agreement contains certain customary representations and warranties, conditions, affirmative and negative covenants and events of default. The Company is in compliance with such covenants as of March 31, 2024.

Voluntary prepayments of amounts outstanding under the Huntington Loans are permitted at any time without premium or penalty.

The Company incurred debt origination fees of $402,000 related to the Huntington Credit Agreement, which is being amortized over the life of the agreement.

Huntington Capex Loan

Pursuant to the terms of the Huntington Credit Agreement, Huntington made available to the Company secured Capex loan (the “Huntington Capex Loan”) in the maximum aggregate principal amount of $25,000,000. Proceeds of the Huntington Capex Loan will be used to finance the ongoing capital expenditure needs of the Company.

Any borrowings from the Huntington Capex Loan will be converted to new term loans annually each February, beginning February 2025, and will have monthly principal repayments based on a sixty-month amortization period with all amounts outstanding on the Huntington Capex Loan being fully due on July 22, 2027.

Huntington Revolving Loan

Pursuant to the terms of the Huntington Credit Agreement, Huntington made available to the Company a revolving loan commitment (the “Huntington Revolving Loan”) of $25,000,000. The Company has $25,000,000 of available revolving loans of which none was outstanding as of March 31, 2024 and December 31, 2023, respectively.

The Huntington Credit Agreement makes available to the Company a revolving commitment in the maximum amount of $25,000,000 at the Company’s option at any time during the five-year period following the closing. The revolving loan commitment terminates, and all outstanding borrowings thereunder must be repaid on July 22, 2027.

The interest rate for the Huntington Revolving Loan was 7.11% and 7.11% as of March 31, 2024 and December 31, 2023, respectively.

Huntington Term Loan

Pursuant to the terms of the Huntington Credit Agreement, Huntington made available to the Company a Term Loan commitment (the “Huntington Term Loan”) of $25,000,000 ($25,000,000 of which was advanced to the Company on July 22, 2022). The Huntington Term Loan is to be repaid in monthly installments beginning August 2022 of $104,000 per month for the first 24 months, $156,000 per month for the next 24 months, $208,000 for the next 12 months and the remaining balance to be paid on July 22, 2027. The interest rate for the Huntington Term Loan was 7.11% and 7.11% as of March 31, 2024 and December 31, 2023, respectively.

Interest Rate Swap Agreement

The Company entered into an interest rate swap agreement that became effective July 22, 2022 and continues through July 2027, which was designed as a cash flow hedge for $25,000,000 of the Huntington Term Loan. Under this agreement, the Company will pay a fixed rate of 2.95% to the swap counterparty in exchange for the Term Loans daily variable SOFR. As a result the interest rate paid on the Huntington Term Loan was 4.75% as of March 31, 2024 and December 31, 2023. The fair value of the interest rate swap was an asset of $797,000 and $524,000 at March 31, 2024 and December 31, 2023, respectively.

Leaf Capital Funding

On April 24, 2020 the Company entered into a finance agreement with Leaf Capital Funding of $175,000 for equipment. The parties agreed to a fixed interest rate of 5.50% and a term of 60 months.

Off-Balance Sheet Arrangements

The Company did not have any significant off-balance sheet arrangements as of March 31, 2024 or December 31, 2023.

25

The Company did not have or experience any material changes outside the ordinary course of business as to contractual obligations, including long-term debt obligations, capital lease obligations, operating lease obligations, purchase obligations or other long-term liabilities reflected in the Company’s Consolidated Balance Sheet under GAAP, as of March 31, 2024 and December 31, 2023.

Critical Accounting Policies and Estimates

For information on critical accounting policies and estimates, see Note 2, "Critical Accounting Policies and Estimates," to the consolidated financial statements included herein.

Item 3.    Quantitative and Qualitative Disclosures About Market Risk

Core Molding Technologies’ primary market risk results from changes in the price of commodities used in its manufacturing operations. Core Molding Technologies is also exposed to fluctuations in interest rates and foreign currency fluctuations associated with the Mexican Peso and Canadian Dollar. Core Molding Technologies does not hold any material market risk sensitive instruments for trading purposes. The Company uses derivative financial instruments to hedge exposure to fluctuations in foreign exchange rates and interest rates.

Core Molding Technologies has the following three items that are sensitive to market risks: (1) non-hedged loans under the Huntington Credit Agreement, all of which bear a variable interest rate; (2) non-hedged foreign currency purchases in which the Company purchases Mexican Pesos and Canadian Dollars with United States Dollars to meet certain obligations; and (3) raw material purchases in which Core Molding Technologies purchases various resins, fiberglass, and metal components for use in production. The prices and availability of these materials are affected by the prices of crude oil, natural gas and other feedstocks, tariffs, as well as processing capacity versus demand.

Assuming a hypothetical 10% change in short-term interest rates, interest paid on the Term Loan would be impacted, as the interest rate on these loans is based upon SOFR. It would not, however, have a material effect on earnings before tax as the Company has entered into a hedge to offset changes in SOFR.

Assuming a hypothetical 10% decrease in the United States Dollar to Mexican Peso and Canadian Dollar exchange rate, the Company would be impacted by an increase in operating costs, which would have an adverse effect on operating margins.

Assuming a hypothetical 10% increase in commodity prices, Core Molding Technologies would be impacted by an increase in raw material costs, which would have an adverse effect on operating margins.

Item 4.    Controls and Procedures

As of the end of the period covered by this report, the Company has carried out an evaluation, under the supervision and with the participation of its management, including its Chief Executive Officer and its Chief Financial Officer, of the effectiveness of the design and operation of its disclosure controls and procedures (as defined in Rule 13a-15(e) of the Exchange Act). Based upon this evaluation, the Company’s management, including its Chief Executive Officer and its Chief Financial Officer, concluded that the Company’s disclosure controls and procedures were (i) effective to ensure that information required to be disclosed in the Company’s reports filed or submitted under the Exchange Act was accumulated and communicated to the Company’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure, and (ii) effective to ensure that information required to be disclosed in the Company’s reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms. There were no changes in internal controls over financial reporting (as such term is defined in Exchange Act Rule 13a-15(f)) that occurred in the last fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

Basis of Presentation

BASIS OF PRESENTATION

The accompanying unaudited consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q 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” or the “Company”) at March 31, 2024, and the results of operations and cash flows for the three months ended March 31, 2024. The “Notes to Consolidated Financial Statements” contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2023, should be read in conjunction with these consolidated financial statements.

Core Molding Technologies and its subsidiaries operate in the engineered materials market as one operating segment as a molder of thermoplastic and thermoset structural products. The Company produces and sells molded products for varied markets, including medium and heavy-duty trucks, power sports, building products, industrial and utilities and other commercial markets. Core Molding Technologies has its headquarters in Columbus, Ohio, and operates six production facilities in the United States, Canada and Mexico.

Critical Accounting Policies and Estimates

3 Months Ended

Accounting Policies [Abstract]

Critical Accounting Policies and Estimates

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Principles of Consolidation: 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.

Use of Estimates: The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities, and reported amounts of revenues and expenses during the reporting period. On an on-going basis, management evaluates its estimates and judgments. 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 and conditions.

Revenue Recognition: The Company historically has recognized revenue from two streams, product revenue and tooling revenue. Product revenue is earned from the manufacture and sale of sheet molding compounds and thermoset and thermoplastic products. Revenue from product sales is generally recognized when products are shipped, as the Company transfers control to the customer and is entitled to payment upon shipment. In certain circumstances, the Company recognizes revenue from product sales when products are produced and the customer takes control at our production facility.

Tooling revenue is earned from manufacturing multiple tools, molds and assembly equipment as part of a tooling program for a customer. Given that the Company is providing a significant service of producing highly interdependent component parts of the tooling program, each tooling program consists of a single performance obligation to provide the customer the capability to produce a single product. Based on the arrangement with the customer, the Company recognizes revenue either at a point in time or over a given period. When the Company does not have an enforceable right to payment, the Company recognizes tooling revenue at a point in time. In such cases, the Company recognizes revenue upon customer acceptance, which is when the customer has legal title to the tools.

Certain tooling programs include an enforceable right to payment. In those cases, the Company recognizes revenue over time based on the extent of progress towards completion of its performance obligation. The Company uses a cost-to-cost measure of progress for such contracts because it best depicts the transfer of value to the customer and also correlates with the amount of consideration to which the entity expects to be titled in exchange for transferring the promised goods or services to the customer. Under the cost-to-cost measure of progress, progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. Revenues are recorded proportionally as costs are incurred.

Cash and Cash Equivalents: The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Cash is held primarily in three banks in three separate jurisdictions. The Company had $26,618,000 cash on hand at March 31, 2024 and had $24,104,000 cash on hand at December 31, 2023.

Accounts Receivable Allowances: Management maintains allowances for credit losses resulting from the inability of its customers to make required payments. If the financial condition of the Company’s customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required. The Company has determined that a $90,000 allowance for credit losses is needed at March 31, 2024 and none is needed at December 31, 2023. Management also records estimates for customer returns and deductions, discounts offered to customers, and for price adjustments. Should customer returns and deductions, discounts, and price adjustments fluctuate from the estimated amounts, additional allowances may be required. The Company had an allowance for estimated chargebacks of $123,000 at March 31, 2024 and $138,000 at December 31, 2023. There have been no material changes in the methodology of these calculations.

Inventories: Inventories, which include material, labor and manufacturing overhead, are valued at the lower of cost or net realizable value. The inventories are accounted for using the first-in, first-out (FIFO) method of determining inventory costs. Inventory quantities on-hand are regularly reviewed, and where necessary, provisions for excess and obsolete inventory are recorded based on historical and anticipated usage. The Company has recorded an allowance for slow moving and obsolete inventory of $730,000 at March 31, 2024 and $671,000 at December 31, 2023.

Contract Assets/Liabilities: Contract assets and liabilities represent the net cumulative customer billings, vendor payments and revenue recognized for tooling programs. For tooling programs where net revenue recognized and vendor payments exceed customer billings, the Company recognizes a contract asset. For tooling programs where net customer billings exceed revenue recognized and vendor payments, the Company recognizes a contract liability. Customer payment terms vary by contract and can range from progress payments based on work performed or one single payment once the contract is completed. The Company has recorded contract assets of $80,000 at March 31, 2024, and $77,000 at December 31, 2023. Contract assets are generally classified as current within prepaid expenses and other current assets on the Consolidated Balance Sheets. For the three months ended March 31, 2024 and March 31, 2023 the Company recognized no impairments on contract assets. For the three months ended March 31, 2024, the Company recognized $1,841,000 of revenue from contract liabilities related to open jobs outstanding as of December 31, 2023.

Income Taxes: The Company evaluates the balance of deferred tax assets that will be realized based on the premise that the Company is more-likely-than-not to realize deferred tax benefits through the generation of future taxable income.

Long-Lived Assets: Long-lived assets consist primarily of property, plant and equipment and definite-lived intangibles. The recoverability of long-lived assets is evaluated by an analysis of operating results and consideration of other significant events or changes in the business environment. The Company evaluates whether impairment exists for property, plant and equipment on the basis of undiscounted expected future cash flows from operations before interest. There were no impairment charges of the Company’s long-lived assets for the three months ended March 31, 2024 and March 31, 2023, respectively.

Goodwill: The purchase consideration of acquired businesses has been allocated to the assets and liabilities acquired based on the estimated fair values on the respective acquisition dates. Based on these values, the excess purchase consideration over the fair value of the net assets acquired was allocated to goodwill. The Company accounts for goodwill in accordance with FASB ASC Topic 350, Intangibles - Goodwill and Other. FASB ASC Topic 350 prohibits the amortization of goodwill and requires these assets be reviewed for impairment.

The annual impairment tests of goodwill may be completed through qualitative assessments; however, the Company may elect to bypass the qualitative assessment and proceed directly to a quantitative impairment test for any period. The Company may resume the qualitative assessment in any subsequent period.

Under a qualitative and quantitative approach, the impairment test for goodwill consists of an assessment of whether it is more-likely-than-not that the fair value is less than its carrying amount. As part of the qualitative assessment, the Company considers relevant events and circumstances that affect the fair value or carrying amount of the Company. Such events and circumstances could include changes in economic conditions, industry and market conditions, cost factors, overall financial performance, and capital markets pricing. The Company places more weight on the events and circumstances that most affect the Company's fair value or carrying amount. These factors are all considered by management in reaching its conclusion about whether to perform step one of the impairment test. If the Company elects to bypass the qualitative assessment, or if a qualitative assessment indicates it is more-likely-than-not that the estimated carrying value exceeds its fair value, the Company proceeds to a quantitative approach. There were no impairment charges of the Company's goodwill for the three months ended March 31, 2024 and March 31, 2023, respectively.

Self-Insurance: The Company is self-insured with respect to its facilities in Columbus, Ohio; Gaffney, South Carolina; Winona, Minnesota; and Brownsville, Texas for medical, dental and vision claims and Columbus, Ohio for workers’ compensation claims, all of which are subject to stop-loss insurance thresholds. The Company is also self-insured for dental and

vision with respect to its Cobourg, Canada location. The Company has recorded an estimated liability for self-insured medical, dental and vision claims incurred but not reported and worker’s compensation claims incurred but not reported at March 31, 2024 and December 31, 2023 of $997,000 and $988,000, respectively. Estimated liabilities for self-insurance are classified as current within accrued other liabilities on the Consolidated Balance Sheets.

Post-Retirement Benefits: Management records an accrual for post-retirement costs associated with the health care plan sponsored by Core Molding Technologies. 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 effect on Core Molding Technologies’ operations. The effect of a change in healthcare costs is described in Note 12, "Post Retirement Benefits", of the Notes to Consolidated Financial Statements contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2023. Core Molding Technologies had a liability for post-retirement healthcare benefits based on actuarial computed estimates of $3,008,000 at March 31, 2024 and $3,116,000 at December 31, 2023.

Earnings Per Share [Abstract]

Net Income Per Common Share

NET INCOME PER COMMON SHARE

Net income per common share is computed based on the weighted average number of common shares outstanding during the period. Diluted net income per common share is computed similarly but includes the effect of the assumed exercise of dilutive stock appreciation rights and restricted stock under the treasury stock method.

On May 13, 2021, the Company's stockholders approved the 2021 Long Term Equity Incentive Plan (the “2021 Plan”) that replaced the 2006 Long Term Equity Incentive Plan (the “2006 Plan”) approved in May 2006 and amended in May 2015. The 2021 Plan provides restricted stock award recipients voting rights equivalent to the Company's common stock and accrual of dividends but not receipt of dividends until all conditions or restrictions related to such award have been satisfied. Accordingly, the restricted shares are not considered participating shares. The 2006 Plan provides restricted stock award recipients voting rights equivalent to the Company’s common stock and accrual and receipt of dividends irrespective of any conditions or restrictions related to such award being satisfied. Accordingly, the restricted shares granted from the 2006 Plan are considered a participating security and the Company is required to apply the two-class method to consider the impact of the restricted shares on the calculation of basic and diluted earnings per share.

The computation of basic and diluted net income per common share (in thousands, except for per share data) is as follows:

	Three months ended March 31,
	2024		2023
Net income	$	3,759	$	5,852
Less: net income allocated to participating securities	—		54
Net income available to common stockholders	$	3,759	$	5,798
Weighted average common shares outstanding — basic	8,666,000		8,418,000
Effect of weighted average dilutive securities	166,000		334,000
Weighted average common and potentially issuable common shares outstanding — diluted	8,832,000		8,752,000
Basic net income per common share	$	0.43	$	0.69

Leases

LEASES

The Company has operating leases with fixed payment terms for certain buildings and warehouses. The Company's leases have remaining lease terms of less than one year to four years, some of which include options to extend the lease for five years. Operating leases are included in operating lease right-of-use ("ROU") assets, accrued other liabilities and other non-current liabilities in the Consolidated Balance Sheets. ROU assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease.

The Company used the applicable incremental borrowing rate at implementation date to measure lease liabilities and ROU assets. The incremental borrowing rate used by the Company was based on baseline rates and adjusted by the credit spreads commensurate with the Company’s secured borrowing rate. At each reporting period when there is a new lease initiated, the Company will utilize its incremental borrowing rate to perform lease classification tests on lease components and to measure ROU assets and lease liabilities.

The components of lease expense were as follows (in thousands):

	Three months ended March 31,

Huntington Credit Agreement

On July 22, 2022, the Company entered into a credit agreement (the “Huntington Credit Agreement”) with The Huntington National Bank (“Huntington”), as the sole lender, administrative agent, lead arranger and book runner, and the lenders from time to time thereto. Pursuant to the terms of the Huntington Credit Agreement, Huntington made available to the Company secured loans (the “Huntington Loans”) in the maximum aggregate principal amount of $75,000,000, comprised of three $25,000,000 commitments: a term loan commitment, a CapEx loan commitment and a revolving loan commitment.

At the option of the Company, the Huntington Loans shall be comprised of Alternative Base Rate (ABR) Loans or Secure Overnight Financing Rate (SOFR) Loans.

ABR Loans bear interest at a per annum rate equal to ABR plus a margin of 280 to 330 basis points determined based on the Company’s leverage ratio. ABR is the greatest of (a) the Prime Rate in effect on such day, (b) the Federal Funds Rate in effect on such day plus 0.50% per annum and (c) Daily Simple SOFR for such day (taking into account any floor set forth in the definition of “Daily Simple SOFR”) plus 1.00% per annum; provided, that if the ABR shall be less than 0.00%, then ABR shall be deemed to be 0.00%.

SOFR Loans bear interest at a per annum rate equal to Daily Simple SOFR plus a margin of 180 to 230 basis points determined based on the Company’s leverage ratio. Daily Simple SOFR means, for any day (a “SOFR Rate Day”), a rate per annum equal to the greater of (a) SOFR for the day (such day, the “SOFR Determination Date”) that is five (5) U.S. Government Securities

Business Days prior to (i) if such SOFR Rate Day is a U.S. Government Securities Business Day, such SOFR Rate Day or (ii) if such SOFR Rate Day is not a U.S. Government Securities Business Day, the U.S. Government Securities Business Day immediately preceding such SOFR Rate Day, in each case, as such SOFR is published by the SOFR Administrator on the SOFR Administrator’s Website, and (b) 0.00%.

The Company’s obligations under the Huntington Credit Agreement are secured by all of the U.S. and Canadian assets of the Company, including all of its equity interests in each of the Company’s U.S. and Canadian subsidiaries and 65% of the Company’s equity interest in its Mexican subsidiaries, and are unconditionally guaranteed by certain subsidiaries of the Company.

The Huntington Credit Agreement contains certain customary representations and warranties, conditions, affirmative and negative covenants and events of default. The Company is in compliance with such covenants as of March 31, 2024.

Voluntary prepayments of amounts outstanding under the Huntington Loans are permitted at any time without premium or penalty.

The Company incurred debt origination fees of $402,000 related to the Huntington Credit Agreement, which is being amortized over the life of the agreement.

Huntington Capex Loan

Pursuant to the terms of the Huntington Credit Agreement, Huntington made available to the Company secured Capex loan (the “Huntington Capex Loan”) in the maximum aggregate principal amount of $25,000,000. Proceeds of the Huntington Capex Loan will be used to finance the ongoing capital expenditure needs of the Company.

Any borrowings from the Huntington Capex Loan will be converted to new term loans annually each February, beginning February 2025, and will have monthly principal repayments based on a sixty-month amortization period with all amounts outstanding on the Huntington Capex Loan being fully due on July 22, 2027.

Huntington Revolving Loan

Pursuant to the terms of the Huntington Credit Agreement, Huntington made available to the Company a revolving loan commitment (the “Huntington Revolving Loan”) of $25,000,000. The Company has $25,000,000 of available revolving loans of which none was outstanding as of March 31, 2024 and December 31, 2023, respectively.

The Huntington Credit Agreement makes available to the Company a revolving commitment in the maximum amount of $25,000,000 at the Company’s option at any time during the five-year period following the closing. The revolving loan commitment terminates, and all outstanding borrowings thereunder must be repaid on July 22, 2027.

The interest rate for the Huntington Revolving Loan was 7.11% and 7.11% as of March 31, 2024 and December 31, 2023, respectively.

Huntington Term Loan

Pursuant to the terms of the Huntington Credit Agreement, Huntington made available to the Company a Term Loan commitment (the “Huntington Term Loan”) of $25,000,000 ($25,000,000 of which was advanced to the Company on July 22, 2022). The Huntington Term Loan is to be repaid in monthly installments beginning August 2022 of $104,000 per month for the first 24 months, $156,000 per month for the next 24 months, $208,000 for the next 12 months and the remaining balance to be paid on July 22, 2027. The interest rate for the Huntington Term Loan was 7.11% and 7.11% as of March 31, 2024 and December 31, 2023, respectively.

Interest Rate Swap Agreement

The Company entered into an interest rate swap agreement that became effective July 22, 2022 and continues through July 2027, which was designed as a cash flow hedge for $25,000,000 of the Huntington Term Loan. Under this agreement, the Company will pay a fixed rate of 2.95% to the swap counterparty in exchange for the Term Loans daily variable SOFR. As a result the interest rate paid on the Huntington Term Loan was 4.75% as of March 31, 2024 and December 31, 2023. The fair value of the interest rate swap was an asset of $797,000 and $524,000 at March 31, 2024 and December 31, 2023, respectively.

Leaf Capital Funding

Income Taxes

INCOME TAXES

The Company evaluates the balance of deferred tax assets that will be realized based on the premise that the Company is more-likely-than-not to realize deferred tax benefits through the generation of future taxable income. Management makes assumptions, judgments, and estimates to determine the deferred tax assets and liabilities. The Company evaluates provisions and deferred tax assets quarterly to determine if adjustments to our valuation allowance are required based on the consideration of all available evidence.

At March 31, 2024, the Company had a net deferred tax asset of $1,595,000 related to tax positions in Mexico and deferred tax liabilities of $1,182,000 and $43,000 related to tax positions in the United States and Canada. Deferred tax assets are included in "Other non-current assets" on the Consolidated Balance Sheets and deferred tax liabilities are included in "Other non-current liabilities" on the Consolidated Balance Sheets. As of March 31, 2024, the Company had a valuation allowance of $1,530,000, against the deferred tax asset related to local tax positions in the Unites States, due to cumulative losses over the last three years and uncertainty related to the Company's ability to realize the deferred assets. The Company believes that the deferred tax assets associated with the Canadian, Mexican, and federal United States tax jurisdictions are more-likely-than-not to be realizable based on estimates of future taxable income.

Income tax expense for the three months ended March 31, 2024 is estimated to be $1,029,000, approximately 21.5% of income before income taxes. Income tax expense for the three months ended March 31, 2023 was estimated to be $1,919,000, approximately 24.7% of income before income taxes.

The Company files income tax returns in the United States, Mexico, Canada and various state and local jurisdictions. The Company is subject to federal income tax examinations for tax years 2014 through 2017 but the scope of examination is limited to adjustments resulting from Net Operating Loss carry back claims from the 2019, and 2020 tax years. The Company is subject to federal income tax examinations for years 2020 through 2023 with unlimited scope. The Company is not subject to state examinations for years before 2020. The Company is not subject to Mexican income tax examinations by Mexican authorities for the years before 2018 and is not subject to Canadian income tax examinations by Canadian authorities for the years before 2019.

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments

FAIR VALUE OF FINANCIAL INSTRUMENTS

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in a transaction between market participants as of the measurement date. Fair value is measured using the fair value hierarchy and related valuation methodologies as defined in the authoritative literature. This hierarchical valuation methodology provides a fair value framework that describes the categorization of assets and liabilities in three levels based upon the assumptions (inputs) used to price the assets or liabilities. Level 1 provides the most reliable measure of fair value, whereas Level 3 generally requires significant management judgment.

The three levels are defined as follows:

Level 1 - Quoted prices in active markets for identical assets and liabilities.

Level 2 - Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-derived valuations, in which all significant inputs are observable in active markets.

Level 3 -Significant unobservable inputs reflecting management's own assumptions about the inputs used in pricing the asset or liability.

The Company’s financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable, debt, interest rate swaps and foreign currency derivatives. Cash and cash equivalents, accounts receivable and accounts payable carrying values as of March 31, 2024 and December 31, 2023 approximate fair value due to the short-term maturities of these financial instruments. As of March 31, 2024 and December 31, 2023, the carrying amounts of the Huntington Term Loan and Huntington Revolving Loan approximated fair value due to the short-term nature of the underlying variable rate SOFR used to determine interest charged on the loans. The Company had Level 2 fair value measurements at March 31, 2024 relating to the Company’s interest rate swaps and foreign currency derivatives.

Derivative and hedging activities

Foreign Currency Derivatives

The Company conducted business in foreign countries and paid certain expenses in foreign currencies; therefore, the Company was exposed to foreign currency exchange risk between the U.S. Dollar and foreign currencies, which could impact the Company’s operating income and cash flows. To mitigate risk associated with foreign currency exchange, the Company entered into forward contracts to exchange a fixed amount of U.S. Dollars for a fixed amount of foreign currency, which will be used to fund future foreign currency cash flows. At inception, all forward contracts are formally documented as cash flow hedges and are measured at fair value each reporting period.

Derivatives are formally assessed both at inception and at least quarterly thereafter, to ensure that derivatives used in hedging transactions are highly effective in offsetting changes in cash flows of the hedged item. If it is determined that a derivative ceases to be a highly effective hedge, or if the anticipated transaction is no longer probable of occurring, hedge accounting is discontinued, and any future mark-to-market adjustments are recognized in earnings. The effective portion of gain or loss is reported in other comprehensive income and the ineffective portion is reported in earnings. The impacts of these contracts were largely offset by gains and losses resulting from the impact of changes in exchange rates on transactions denominated in the foreign currency. As of March 31, 2024, the Company had no ineffective portion related to the cash flow hedges. The notional contract value of foreign currency derivatives was $5,063,000 and $28,592,000 as of March 31, 2024 and 2023, respectively.

Interest Rate Swap

The Company entered into an interest rate swap contract to fix the interest rate on an initial aggregate amount of $25,000,000 thereby reducing exposure to interest rate changes. The interest rate swap pays a fixed rate of 2.95% to the swap counterparty in exchange for daily SOFR. At inception, all interest rate swaps were formally documented as cash flow hedges and are measured at fair value each reporting period. See Note 10, "Debt", for additional information. The notional contract value of the interest rate swap was $22,917,000 and $24,167,000 as of March 31, 2024 and 2023, respectively.

Critical Accounting Policies and Estimates (Policies)

3 Months Ended

Mar. 31, 2024

Accounting Policies [Abstract]

Principles of Consolidation

Principles of Consolidation: 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.

Use of Estimates

Use of Estimates: The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities, and reported amounts of revenues and expenses during the reporting period. On an on-going basis, management evaluates its estimates and judgments. 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 and conditions.

Revenue Recognition

Revenue Recognition: The Company historically has recognized revenue from two streams, product revenue and tooling revenue. Product revenue is earned from the manufacture and sale of sheet molding compounds and thermoset and thermoplastic products. Revenue from product sales is generally recognized when products are shipped, as the Company transfers control to the customer and is entitled to payment upon shipment. In certain circumstances, the Company recognizes revenue from product sales when products are produced and the customer takes control at our production facility.

Tooling revenue is earned from manufacturing multiple tools, molds and assembly equipment as part of a tooling program for a customer. Given that the Company is providing a significant service of producing highly interdependent component parts of the tooling program, each tooling program consists of a single performance obligation to provide the customer the capability to produce a single product. Based on the arrangement with the customer, the Company recognizes revenue either at a point in time or over a given period. When the Company does not have an enforceable right to payment, the Company recognizes tooling revenue at a point in time. In such cases, the Company recognizes revenue upon customer acceptance, which is when the customer has legal title to the tools.

Certain tooling programs include an enforceable right to payment. In those cases, the Company recognizes revenue over time based on the extent of progress towards completion of its performance obligation. The Company uses a cost-to-cost measure of progress for such contracts because it best depicts the transfer of value to the customer and also correlates with the amount of consideration to which the entity expects to be titled in exchange for transferring the promised goods or services to the customer. Under the cost-to-cost measure of progress, progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. Revenues are recorded proportionally as costs are incurred.

Cash and Cash Equivalents: The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Cash is held primarily in three banks in three separate jurisdictions. The Company had $26,618,000 cash on hand at March 31, 2024 and had $24,104,000 cash on hand at December 31, 2023.

Accounts Receivable Allowances

Accounts Receivable Allowances: Management maintains allowances for credit losses resulting from the inability of its customers to make required payments. If the financial condition of the Company’s customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required. The Company has determined that a $90,000 allowance for credit losses is needed at March 31, 2024 and none is needed at December 31, 2023. Management also records estimates for customer returns and deductions, discounts offered to customers, and for price adjustments. Should customer returns and deductions, discounts, and price adjustments fluctuate from the estimated amounts, additional allowances may be required. The Company had an allowance for estimated chargebacks of $123,000 at March 31, 2024 and $138,000 at December 31, 2023. There have been no material changes in the methodology of these calculations.

Inventories

Inventories: Inventories, which include material, labor and manufacturing overhead, are valued at the lower of cost or net realizable value. The inventories are accounted for using the first-in, first-out (FIFO) method of determining inventory costs. Inventory quantities on-hand are regularly reviewed, and where necessary, provisions for excess and obsolete inventory are recorded based on historical and anticipated usage. The Company has recorded an allowance for slow moving and obsolete inventory of $730,000 at March 31, 2024 and $671,000 at December 31, 2023.

Contract Assets/Liabilities

Contract Assets/Liabilities: Contract assets and liabilities represent the net cumulative customer billings, vendor payments and revenue recognized for tooling programs. For tooling programs where net revenue recognized and vendor payments exceed customer billings, the Company recognizes a contract asset. For tooling programs where net customer billings exceed revenue recognized and vendor payments, the Company recognizes a contract liability. Customer payment terms vary by contract and can range from progress payments based on work performed or one single payment once the contract is completed. The Company has recorded contract assets of $80,000 at March 31, 2024, and $77,000 at December 31, 2023. Contract assets are generally classified as current within prepaid expenses and other current assets on the Consolidated Balance Sheets. For the three months ended March 31, 2024 and March 31, 2023 the Company recognized no impairments on contract assets. For the three months ended March 31, 2024, the Company recognized $1,841,000 of revenue from contract liabilities related to open jobs outstanding as of December 31, 2023.

Income Taxes

Income Taxes: The Company evaluates the balance of deferred tax assets that will be realized based on the premise that the Company is more-likely-than-not to realize deferred tax benefits through the generation of future taxable income.

Long-Lived Assets

Long-Lived Assets: Long-lived assets consist primarily of property, plant and equipment and definite-lived intangibles. The recoverability of long-lived assets is evaluated by an analysis of operating results and consideration of other significant events or changes in the business environment. The Company evaluates whether impairment exists for property, plant and equipment on the basis of undiscounted expected future cash flows from operations before interest. There were no impairment charges of the Company’s long-lived assets for the three months ended March 31, 2024 and March 31, 2023, respectively.

Goodwill

Goodwill: The purchase consideration of acquired businesses has been allocated to the assets and liabilities acquired based on the estimated fair values on the respective acquisition dates. Based on these values, the excess purchase consideration over the fair value of the net assets acquired was allocated to goodwill. The Company accounts for goodwill in accordance with FASB ASC Topic 350, Intangibles - Goodwill and Other. FASB ASC Topic 350 prohibits the amortization of goodwill and requires these assets be reviewed for impairment.

The annual impairment tests of goodwill may be completed through qualitative assessments; however, the Company may elect to bypass the qualitative assessment and proceed directly to a quantitative impairment test for any period. The Company may resume the qualitative assessment in any subsequent period.

Under a qualitative and quantitative approach, the impairment test for goodwill consists of an assessment of whether it is more-likely-than-not that the fair value is less than its carrying amount. As part of the qualitative assessment, the Company considers relevant events and circumstances that affect the fair value or carrying amount of the Company. Such events and circumstances could include changes in economic conditions, industry and market conditions, cost factors, overall financial performance, and capital markets pricing. The Company places more weight on the events and circumstances that most affect the Company's fair value or carrying amount. These factors are all considered by management in reaching its conclusion about whether to perform step one of the impairment test. If the Company elects to bypass the qualitative assessment, or if a qualitative assessment indicates it is more-likely-than-not that the estimated carrying value exceeds its fair value, the Company proceeds to a quantitative approach. There were no impairment charges of the Company's goodwill for the three months ended March 31, 2024 and March 31, 2023, respectively.

Self-Insurance

Self-Insurance: The Company is self-insured with respect to its facilities in Columbus, Ohio; Gaffney, South Carolina; Winona, Minnesota; and Brownsville, Texas for medical, dental and vision claims and Columbus, Ohio for workers’ compensation claims, all of which are subject to stop-loss insurance thresholds. The Company is also self-insured for dental and

vision with respect to its Cobourg, Canada location. The Company has recorded an estimated liability for self-insured medical, dental and vision claims incurred but not reported and worker’s compensation claims incurred but not reported at March 31, 2024 and December 31, 2023 of $997,000 and $988,000, respectively. Estimated liabilities for self-insurance are classified as current within accrued other liabilities on the Consolidated Balance Sheets.

Post-retirement Benefits

Post-Retirement Benefits: Management records an accrual for post-retirement costs associated with the health care plan sponsored by Core Molding Technologies. 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 effect on Core Molding Technologies’ operations. The effect of a change in healthcare costs is described in Note 12, "Post Retirement Benefits", of the Notes to Consolidated Financial Statements contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2023. Core Molding Technologies had a liability for post-retirement healthcare benefits based on actuarial computed estimates of $3,008,000 at March 31, 2024 and $3,116,000 at December 31, 2023.

Fair Value Measurement

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in a transaction between market participants as of the measurement date. Fair value is measured using the fair value hierarchy and related valuation methodologies as defined in the authoritative literature. This hierarchical valuation methodology provides a fair value framework that describes the categorization of assets and liabilities in three levels based upon the assumptions (inputs) used to price the assets or liabilities. Level 1 provides the most reliable measure of fair value, whereas Level 3 generally requires significant management judgment.

The three levels are defined as follows:

Level 1 - Quoted prices in active markets for identical assets and liabilities.

Level 2 - Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-derived valuations, in which all significant inputs are observable in active markets.

Level 3 -Significant unobservable inputs reflecting management's own assumptions about the inputs used in pricing the asset or liability.

The Company’s financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable, debt, interest rate swaps and foreign currency derivatives. Cash and cash equivalents, accounts receivable and accounts payable carrying values as of March 31, 2024 and December 31, 2023 approximate fair value due to the short-term maturities of these financial instruments. As of March 31, 2024 and December 31, 2023, the carrying amounts of the Huntington Term Loan and Huntington Revolving Loan approximated fair value due to the short-term nature of the underlying variable rate SOFR used to determine interest charged on the loans. The Company had Level 2 fair value measurements at March 31, 2024 relating to the Company’s interest rate swaps and foreign currency derivatives.

Derivative and hedging activities

Foreign Currency Derivatives

The Company conducted business in foreign countries and paid certain expenses in foreign currencies; therefore, the Company was exposed to foreign currency exchange risk between the U.S. Dollar and foreign currencies, which could impact the Company’s operating income and cash flows. To mitigate risk associated with foreign currency exchange, the Company entered into forward contracts to exchange a fixed amount of U.S. Dollars for a fixed amount of foreign currency, which will be used to fund future foreign currency cash flows. At inception, all forward contracts are formally documented as cash flow hedges and are measured at fair value each reporting period.

Derivatives are formally assessed both at inception and at least quarterly thereafter, to ensure that derivatives used in hedging transactions are highly effective in offsetting changes in cash flows of the hedged item. If it is determined that a derivative ceases to be a highly effective hedge, or if the anticipated transaction is no longer probable of occurring, hedge accounting is discontinued, and any future mark-to-market adjustments are recognized in earnings. The effective portion of gain or loss is reported in other comprehensive income and the ineffective portion is reported in earnings. The impacts of these contracts were largely offset by gains and losses resulting from the impact of changes in exchange rates on transactions denominated in the foreign currency. As of March 31, 2024, the Company had no ineffective portion related to the cash flow hedges. The notional contract value of foreign currency derivatives was $5,063,000 and $28,592,000 as of March 31, 2024 and 2023, respectively.
