FORWARD-LOOKING STATEMENTS AND RISK FACTORS

This Quarterly Report on Form 10-Q (“Form 10-Q”) contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements may be preceded by, followed by or include words such as “could,” “may,” “believe,” “expect,” “anticipate,” “plan,” “estimate,” “expect,” “would,” or similar expressions. These statements are based on the beliefs and assumptions of our management at the time such statements are made. Generally, forward-looking statements include information concerning our possible or assumed future actions, events or results of operations. Forward-looking statements specifically include, without limitation, the information in this Form 10-Q regarding: future sales, earnings, cash flow, revenue recognition, uses of cash and other measures of financial performance, projections or expectations for future operations, including costs to complete contracts, goodwill impairment evaluations, useful life of intangible assets, unrecognized tax benefits and effective tax rate, environmental remediation costs, insurance recoveries, industry trends and expectations, including ramp up times for build rates, our plans with respect to restructuring activities, capital expenditures, completed acquisitions, future acquisitions and dispositions and expected business opportunities that may be available to us.

Although we believe that the expectations reflected in the forward-looking statements are based on reasonable assumptions, these forward-looking statements are subject to numerous factors, risks and uncertainties that could cause actual outcomes and results to be materially different from those projected. We cannot guarantee future results, performance or achievements. Moreover, neither we nor any other person assumes responsibility for the accuracy and completeness of the forward-looking statements. All written and oral forward-looking statements made in connection with this Form 10-Q that are attributable to us or persons acting on our behalf are expressly qualified in their entirety by the “Risk Factors” contained within Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2023 (“Form 10-K”).

There can be no assurance that other factors will not affect the accuracy of these forward-looking statements or that our actual results will not differ materially from the results anticipated in such forward-looking statements. While it is impossible to identify all such factors, some factors that could cause actual results to differ materially from those estimated by us include, but are not limited to, those factors or conditions described under Risk Factors contained within Part I, Item 1A of our Form 10-K and the following:

•our level of indebtedness;

•our ability to service our indebtedness;

•the covenants in our credit facilities impose restrictions that may limit our operating and financial flexibility;

•the typical trading volume of our common stock may affect an investor’s ability to sell significant stock holdings in the future without negatively impacting our stock price;

•our amount of debt may require us to raise additional capital to fund acquisitions;

•our end use markets are cyclical and we depend upon a select base of industries and customers;

•a significant portion of our business depends on the U.S. Government defense spending;

•exports of certain of our products and our production facility in Guaymas, Mexico are subject to various export control regulations and authorizations for proposed sales to certain foreign customers;

•contracts with some of our customers give them a variety of rights that are unfavorable to us and the OEMs to whom we provide products and services, including the ability to terminate a contract at any time for convenience;

•further consolidation in the aerospace industry;

•our ability to execute our growth strategy, which includes evaluating select acquisitions;

•we may not be successful in achieving expected operating efficiencies and sustaining or improving operating expense reductions, and may experience business disruptions associated with restructuring, performance center consolidations, realignment, cost reduction, and other strategic initiatives;

•enhanced design, product development, manufacturing, supply chain project management and other skills will be required as we move up the value chain to become a more value added supplier, and we are dependent upon our ability to attract and retain key personnel;

•risks associated with operating and conducting our business outside the United States;

•customer pricing pressures could reduce the demand and/or price for our products and services;

3

•our products and processes are subject to risk of obsolescence as a result of changes in technology and evolving industrial and regulatory standards;

•we may not have the ability to renew facilities leases on terms favorable to us and relocation of operations presents risks due to business interruptions;

•we are subject to a number of procurement laws with which we must comply;

•our operations are subject to numerous extensive, complex, costly and evolving laws, regulations and restrictions, including the Defense Contract Audit Agency and cybersecurity requirements;

•possible goodwill and other asset impairments;

•the risk of environmental liabilities and our environmental, social and governance, and sustainability responsibilities;

•we may be subject to litigation, other legal proceedings and indemnity claims;

•our ability to implement changes in estimates when bidding on fixed-price contracts;

•unanticipated changes in our tax provision or exposure to additional income tax liabilities;

•our ability to accurately report our financial results or prevent fraud if our internal control over financial reporting is not effective;

•labor disruptions and the ability of our suppliers to meet the quality and delivery expectations of our customers;

•cybersecurity attacks;

•assertions by third parties of violations of intellectual property rights; and

•damage or destruction of our facilities caused by natural disasters.

We caution the reader that undue reliance should not be placed on any forward-looking statements, which speak only as of the date of this Form 10-Q. We do not undertake any duty or responsibility to update any of these forward-looking statements to reflect events or circumstances after the date of this Form 10-Q, except as required by law.

Notes to Condensed Consolidated Financial Statements (Unaudited)

Note 1. Summary of Significant Accounting Policies

Description of Business

We are a leading global provider of innovative, value-added proprietary products and manufacturing solutions for high-performance products and high-cost-of failure applications used primarily in the aerospace and defense (“A&D”), industrial, medical and other industries (collectively, “Industrial”). Our operations are organized into two primary businesses: the Electronic Systems segment (“Electronic Systems”) and the Structural Systems segment (“Structural Systems”), each of which is a reportable operating segment. Electronic Systems designs, engineers and manufactures high-reliability electronic and electromechanical products used in worldwide technology-driven markets including A&D and Industrial end-use markets. Electronic Systems’ product offerings primarily range from prototype development to complex assemblies. Structural Systems designs, engineers and manufactures large, complex contoured aerostructure components and assemblies and supplies composite and metal bonded structures and assemblies. Structural Systems’ products are primarily used on commercial aircraft, military fixed-wing aircraft, and military and commercial rotary-wing aircraft. Both reportable operating segments follow the same accounting principles.

Basis of Presentation

The unaudited condensed consolidated financial statements include the accounts of Ducommun Incorporated and its subsidiaries (“Ducommun,” the “Company,” “we,” “us” or “our”), after eliminating intercompany balances and transactions. The December 31, 2023 condensed consolidated balance sheet data was derived from audited financial statements, but does not contain all disclosures required by accounting principles generally accepted in the United States of America (“GAAP”).

Our significant accounting policies were described in Part IV, Item 15(a)(1), “Note 1. Summary of Significant Accounting Policies” in our Annual Report on Form 10-K for the year ended December 31, 2023 (“2023 Form 10-K”). The financial information included in this Quarterly Report on Form 10-Q (“Form 10-Q”) should be read in conjunction with the 2023 Form 10-K.

In the opinion of management, all adjustments, including recurring accruals, have been made that are necessary to fairly state our condensed consolidated financial position, statements of income, comprehensive income, changes in shareholders’ equity, and cash flows in accordance with GAAP for the periods covered by this Form 10-Q. The results of operations for the three and six months ended June 29, 2024 are not necessarily indicative of the results to be expected for the full year ending December 31, 2024.

Our fiscal quarters typically end on the Saturday closest to the end of March, June and September for the first three fiscal quarters of each year, and on December 31 for our fourth fiscal quarter. As a result of using fiscal quarters for the first three quarters combined with leap years, our first and fourth fiscal quarters can range between 12 1/2 weeks to 13 1/2 weeks while the second and third fiscal quarters remain at a constant 13 weeks per fiscal quarter.

Certain reclassifications have been made to prior period amounts to conform to the current year’s presentation.

Use of Estimates

Certain amounts and disclosures included in the unaudited condensed consolidated financial statements require management to make estimates and judgments that affect the amounts of assets, liabilities (including contract liabilities), revenues and expenses, and related disclosures of contingent assets and liabilities. These estimates are based on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates.

Unsolicited Non-Binding Indication of Interest

On April 8, 2024, our Board of Directors (“BOD”) confirmed receipt of the first unsolicited non-binding indication of interest dated April 1, 2024 (“First IOI”) from Albion River LLC (“Albion”), a private direct investment firm. Albion expressed interest in acquiring all the outstanding shares of Ducommun for $60.00 per share in cash. On April 16, 2024, we issued a press release responding to the First IOI that the BOD had unanimously determined it was not in the best interests of Ducommun and Ducommun shareholders to pursue further discussions regarding the proposal.

Subsequent to our quarter ended June 29, 2024, on July 15, 2024, our BOD received an unsolicited revised non-binding indication of interest from Albion (“Second IOI”), to acquire all outstanding shares of Ducommun for $65.00 per share in cash.

On July 25, 2024, we issued a press release responding to the Second IOI that the BOD had unanimously determined it was not in the best interests of Ducommun and Ducommun shareholders to pursue further discussions regarding the revised proposal.

Earnings Per Share

Basic earnings per share are computed by dividing income available to common shareholders by the weighted-average number of common shares outstanding in each period. Diluted earnings per share is computed by dividing income available to common shareholders by the weighted-average number of common shares outstanding, plus any potentially dilutive shares that could be issued if exercised or converted into common stock in each period.

The net income and weighted-average common shares outstanding used to compute earnings per share were as follows:

Fair Value

Assets and liabilities that are measured, recorded or disclosed at fair value on a recurring basis are categorized using the fair value hierarchy. The fair value hierarchy has three levels based on the reliability of the inputs used to determine the fair value. Level 1, the highest level, refers to the values determined based on quoted prices in active markets for identical assets. Level 2 refers to fair values estimated using significant observable inputs. Level 3, the lowest level, includes fair values estimated using significant unobservable inputs.

We have money market funds which are included as cash and cash equivalents. We also have forward interest rate swap agreements and the fair value of the forward interest rate swap agreements was determined using pricing models that use observable market inputs as of the balance sheet date, a Level 2 measurement.

There were no transfers between Level 1, Level 2, or Level 3 financial instruments in the three months ended June 29, 2024.

11

Cash and Cash Equivalents

Cash equivalents consist of highly liquid instruments purchased with original maturities of three months or less. These assets are valued at cost, which approximates fair value, and we classify as Level 1. See Fair Value above.

Derivative Instruments

We recognize derivative instruments on our condensed consolidated balance sheets at their fair value. On the date that we enter into a derivative contract, we designate the derivative instrument as a fair value hedge, a cash flow hedge, or a derivative instrument that will not be accounted for using hedge accounting methods. In November 2021, we entered into forward interest rate swap agreements with an aggregate notional amount of $150.0 million, all with an effective date of January 1, 2024 (“Forward Interest Rate Swaps”), to manage our exposure to interest rate movements on a portion of our debt. At the time we entered into the Forward Interest Rate Swaps, there was a high probability of forecasted interest payments on our debts occurring and the swaps were highly effective in offsetting those interest payments; therefore, we elected to apply cash flow hedge accounting. In July 2022, as a result of refinancing all our existing debt, which allowed borrowing based on a Secured Overnight Financing Rate (“SOFR”), we were required to complete an amendment of the Forward Interest Rate Swaps from One Month London Interbank Offered Rate (“LIBOR”) to One Month Term SOFR (“Amended Forward Interest Rate Swaps”), which occurred on the same day. After the transition of the Forward Interest Rate Swaps and debt to SOFR was completed, we determined the hedging relationships were still highly effective as of the amendment date. See Note 4 and Note 8. As of June 29, 2024, all of our derivative instruments were designated as cash flow hedges.

We record changes in the fair value of a derivative instrument that is highly effective and that is designated and qualifies as a cash flow hedge in other comprehensive income (loss), net of tax until our earnings are affected by the variability of cash flows of the underlying hedged item. We report changes in the fair values of derivative instruments that are not designated or do not qualify for hedge accounting in current period earnings. We classify cash flows from derivative instruments in the condensed consolidated statements of cash flows in the same category as the item being hedged or on a basis consistent with the nature of the instrument. Prior to the Amended Forward Interest Rate Swaps being effective on January 1, 2024, we only recorded the changes in fair value of the derivative instruments that were highly effective and that were designated and qualified as cash flow hedges prior to the effective date. See Note 4.

When we determine that a derivative instrument is not highly effective as a hedge, we discontinue hedge accounting prospectively. In all situations in which we discontinue hedge accounting and the derivative instrument remains outstanding, we will carry the derivative instrument at its fair value on our condensed consolidated balance sheets and recognize subsequent changes in its fair value in our current period earnings.

Inventories

Inventories are stated at the lower of cost or net realizable value with cost being determined using a moving average cost basis for raw materials and actual cost for work-in-process and finished goods. The majority of our inventory is charged to cost of sales as raw materials are placed into production. Inventoried costs include raw materials, outside processing, direct labor and allocated overhead, adjusted for any abnormal amounts of idle performance center expense, freight, handling costs, and wasted materials (spoilage) incurred. We assess the inventory carrying value and reduce it, if necessary, to its net realizable value based on customer orders on hand, and internal demand forecasts using management’s best estimates given information currently available. The majority of our revenues are recognized over time, however, for revenue contracts where revenue is recognized using the point in time method, inventory is not reduced until it is shipped or transfer of control to the customer has occurred. Our ending inventory consists of raw materials, work-in-process, and finished goods.

Accumulated Other Comprehensive Income

Accumulated other comprehensive income, as reflected on the condensed consolidated balance sheets under the equity section, was comprised of cumulative pension and retirement liability adjustments, net of tax, and change in net unrealized gains and losses on cash flow hedges, net of tax.

Revenue Recognition

Our customers typically engage us to manufacture products based on designs and specifications provided by the end-use customer. This requires the building of tooling and manufacturing first article inspection products (prototypes) before volume manufacturing. Contracts with our customers generally include a termination for convenience clause.

We have a significant number of contracts that are started and completed within the same year, as well as contracts derived from long-term agreements and programs that can span several years. We recognize revenue under ASC 606, “Revenue from Contracts with Customers” (“ASC 606”), which utilizes a five-step model.

12

The definition of a contract for us is typically defined as a customer purchase order as this is when we achieve an enforceable right to payment. The majority of our contracts are firm fixed-price contracts. The deliverables within a customer purchase order are analyzed to determine the number of performance obligations. In addition, at times, in order to achieve economies of scale and based on our customer’s forecasted demand, we may build in advance of receiving a purchase order from our customer. When that occurs, we would not recognize revenue until we have received the customer purchase order.

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account under ASC 606. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, control is transferred and the performance obligation is satisfied. The majority of our contracts have a single performance obligation as the promise to transfer the individual goods or services are highly interrelated or met the series guidance. For contracts with multiple performance obligations, we allocate the contract transaction price to each performance obligation using our best estimate of the standalone selling price of each distinct good or service in the contract. The primary method used to estimate the standalone selling price is the expected cost plus a margin approach, under which we forecast our expected costs of satisfying a performance obligation and then add an appropriate margin for that distinct good or service.

We manufacture most products to customer specifications, and the product cannot be easily modified for another customer. As such, these products are deemed to have no alternative use once the manufacturing process begins. In the event the customer invokes a termination for convenience clause, we would be entitled to costs incurred to date plus a reasonable profit. Contract costs typically include labor, materials, overhead, and when applicable, subcontractor costs. For most of our products, we are building assets with no alternative use and have enforceable right to payment, and thus, we recognize revenue using the over time method.

The majority of our performance obligations are satisfied over time as work progresses. Typically, revenue is recognized over time using an input measure (i.e., costs incurred to date relative to total estimated costs at completion, also known as cost-to-cost plus reasonable profit) to measure progress. Our typical revenue contract is a firm fixed price contract, and the cost of raw materials could make up a significant amount of the total costs incurred. As such, we believe using the total costs incurred input method would be the most appropriate method. While the cost of raw materials could make up a significant amount of the total costs incurred, there is a direct relationship between our inputs and the transfer of control of goods or services to the customer.

Contract estimates, known as estimates at completion, are based on various assumptions to project the outcome of future events that can span multiple months or years. These assumptions include among others, labor productivity and availability; the complexity of the work to be performed; the cost and availability of materials; overhead cost rates; and the performance of subcontractors. As a significant change in one or more of these estimates could affect the progress completed (and related profitability) on our contracts, we review and update our contract-related estimates on a regular basis. We recognize such adjustments under the cumulative catch-up method. Under this method, the impact of the adjustment is recognized in the period the adjustment is identified. In any given reporting period, we have a large number of active contracts, which we have defined as a customer purchase order, and changes in estimates may occur on a significant number of these contracts. Given the significant number of contracts that we may have at any given point in time, the varied nature of products produced under such contracts, and the different assumptions, facts and circumstances associated with each individual contract, and the fact that such changes at the contract level are typically not material, we disclose cumulative catch-up adjustments on a net basis.

Net cumulative favorable and unfavorable catch-up adjustments to contracts had the following impact on our operating results:

	(Dollars in thousands)				(Dollars in thousands)
	Three Months Ended				Six Months Ended
	June 29, 2024		July 1, 2023		June 29, 2024		July 1, 2023
Total net revenues	$	387	$	(4,184)	$	(1,548)	$	(7,440)
Operating income	$	387	$	(4,184)	$	(1,548)	$	(7,440)

Payments under long-term contracts may be received before or after revenue is recognized. When revenue is recognized before we bill our customer, a contract asset is created for the work performed but not yet billed. Similarly, when we receive payment before we ship our products to our customer and have met the shipping terms, a contract liability is created for the advance or progress payment. When a contract liability and a contract asset exist on the same contract, we report it on a net basis.

We record provisions for the total anticipated losses on contracts, considering total estimated costs to complete the contract compared to total anticipated revenues, in the period in which such losses are identified. The provisions for estimated losses on contracts require us to make certain estimates and assumptions, including those with respect to the future revenue under a contract and the future cost to complete the contract. Our estimate of the future cost to complete a contract may include assumptions as to changes in manufacturing efficiency, operating and material costs, and our ability to resolve claims and assertions with our customers. If any of these or other assumptions and estimates do not materialize in the future, we may be

13

required to adjust the provisions for estimated losses on contracts. The provision for estimated losses on contracts is included as part of contract liabilities on the condensed consolidated balance sheets. As of June 29, 2024 and December 31, 2023, provision for estimated losses on contracts were $5.2 million and $5.4 million, respectively. It is reasonably possible we may incur additional losses in the future.

Production cost of contracts includes non-recurring production costs, such as design and engineering costs, and tooling and other special-purpose machinery necessary to build parts as specified in a contract. Production costs of contracts are recorded to cost of sales using the over time revenue recognition model. We review the value of the production cost of contracts on a quarterly basis to ensure when added to the estimated cost to complete, the value is not greater than the estimated realizable value of the related contracts. As of June 29, 2024 and December 31, 2023, production cost of contracts were $6.2 million and $7.8 million, respectively.

Contract Assets and Contract Liabilities

Contract assets consist of our right to payment for work performed but not yet billed. Contract assets are transferred to accounts receivable when we bill our customers. We bill our customers when we ship the products and meet the shipping terms within the revenue contract. Contract liabilities consist of advance or progress payments received from our customers prior to the time transfer of control occurs plus the estimated losses on contracts. When a contract liability and a contract asset exist on the same contract, we report it on a net basis.

Contract assets and contract liabilities from revenue contracts with customers are as follows:

	(Dollars in thousands)
	June 29, 2024		December 31, 2023
Contract assets	$	210,314	$	177,686
Contract liabilities	$	50,034	$	53,492

The increase in our contract assets as of June 29, 2024 compared to December 31, 2023 was primarily due to a net increase of products in work in process in the current period.

The decrease in our contract liabilities as of June 29, 2024 compared to December 31, 2023 was primarily due to a net decrease of advance or progress payments received from our customers in the current period. We recognized $21.0 million of the contract liabilities as of December 31, 2023 as revenues during the six months ended June 29, 2024.

Performance obligations are defined as customer placed purchase orders (“POs”) with firm fixed price and firm delivery dates. Our remaining performance obligations as of June 29, 2024 totaled $840.0 million. Of the remaining performance obligations as of June 29, 2024, we anticipate recognizing an estimated 65% of our remaining performance obligations as revenue during the next 12 months with the remaining performance obligations being recognized in the remainder of 2025 and beyond.

Recent Accounting Pronouncements

Recently Issued Accounting Standards

In March 2024, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2024-02, “Codification Improvements - Amendments to Remove References to the Concepts Statements” (“ASU 2024-02”), which removed references to various FASB Concepts Statements and updates technical corrections such as conforming amendments, clarification to guidance, simplifications to wording or the structure of guidance, and other minor improvements. The new guidance is effective for fiscal years beginning after December 15, 2024, which is our annual period beginning January 1, 2025. Early adoption is permitted. We are evaluating the impact of this standard.

In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“ASU 2023-09”), which provides more transparency about tax information primarily related to the rate reconciliation and the income taxes paid. The new guidance is effective for fiscal years beginning after December 15, 2024, which will be our annual period beginning January 1, 2025. Early adoption is permitted. We are evaluating the impact of this standard.

In November 2023, the FASB issued ASU 2023-07, “Segment Reporting (Topic 280), Improvements to Reportable Segment Disclosures” (“ASU 2023-07”), which expands reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The new guidance is effective for fiscal years beginning after December 15, 2023, which is our annual period beginning January 1, 2024, and interim periods within fiscal years beginning after December 15, 2024, which will be our interim period beginning January 1, 2025. Early adoption is permitted. We are evaluating the impact of this standard.

In October 2023, the FASB issued ASU 2023-06, “Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative” (“ASU 2023-06”), which incorporates updates to the Accounting Standards Codification to align certain SEC disclosure requirements. The amendments impact a variety of topics but are relatively narrow in nature. For entities required to comply with the SEC’s existing disclosure requirements, the effective date for each amendment will be the effective date of the removal of the disclosure requirement from SEC Regulation S-X or SEC Regulation S-K, with early adoption prohibited. The amendments should be applied prospectively. We are evaluating the impact of this standard.

Note 2. Business Combinations

BLR Aerospace, L.L.C. Acquisition

In April 2023, we acquired 100.0% of the outstanding equity interests of BLR Aerospace, L.L.C. (“BLR”), a privately-held leading provider of aerodynamic systems that enhance the productivity, performance, and safety of rotary and fixed-wing aircraft on commercial and military platforms. BLR is located in Everett, Washington. The acquisition of BLR added to our strategy to diversify and offer more customized, value-driven engineered products with aftermarket opportunities.

The initial purchase price for BLR was $115.0 million, net of cash acquired, all payable in cash, subject to adjustments for working capital. We paid a gross aggregate of $117.0 million in cash upon the closing of the transaction. Subsequent to the closing of the transaction, during the three months ended September 30, 2023, the working capital was finalized, resulting in an immaterial adjustment for a final purchase price of $114.4 million, net of cash acquired. We allocated the gross purchase price of $117.0 million to the assets acquired and liabilities assumed at their estimated fair values. The excess of the purchase price over the aggregate fair values of the net assets was recorded as goodwill.

The following table summarizes the estimated fair value of the assets acquired and liabilities assumed at the date of acquisition (in thousands):

	Estimated Fair Value
Cash	$	2,656
Accounts receivable	4,149
Inventories	12,011
Other current assets	891
Property and equipment	2,632
Operating lease right-of-use assets	874
Intangible assets	55,500
Goodwill	41,193
Total assets acquired	119,906
Current liabilities	(2,145)
Other non-current liabilities	(727)
Total liabilities assumed	(2,872)
Total purchase price allocation	$	117,034

	Useful Life (In years)	Estimated Fair Value (In thousands)
Intangible assets:
Technology	23	$	35,600
Customer relationships	10-22	15,000
Trade name	18	4,900
		$	55,500

The intangible assets acquired of $55.5 million were determined based on the estimated fair values using valuation techniques consistent with the income approach to measure fair value, which represented Level 3 fair value measurements. The useful lives were estimated based on the underlying agreements or the future economic benefit expected to be received from the assets. The values for technology and trade name were assessed using the relief from royalty methodology, while the value for customer relationships was estimated based on a multi-period excess earnings approach. Inputs to the income approach models and other aspects of the allocation of the purchase price require judgment. The more significant inputs used in the technology intangible asset valuation included (i) future revenues, (ii) the technology decay rate, (iii) the royalty rate, and (iv) the discount rate. The more significant inputs used in the customer relationships intangible asset valuation included (i) future revenues, (ii) the projected earnings before interest, taxes, and amortization (“EBITA”) margins, (iii) the customer attrition rates, and (iv) the discount rate.

The goodwill of $41.2 million arising from the acquisition is attributable to the benefits we expect to derive from expected synergies from the transaction, including complementary products that will enhance our overall product portfolio, opportunities within new markets, and an acquired assembled workforce. All the goodwill was assigned to the Structural Systems segment.

16

The BLR acquisition, for tax purposes, is deemed an asset acquisition and thus, the goodwill recognized is deductible for income tax purposes.

Acquisition related transaction costs were not included as components of consideration transferred but have been expensed as incurred. Total acquisition-related transaction costs incurred by us were zero and $0.5 million during the three months ended June 29, 2024 and July 1, 2023, respectively, and zero and $1.3 million during the six months ended June 29, 2024 and July 1, 2023, respectively, and charged to selling, general and administrative expenses.

BLR’s results of operations have been included in our condensed consolidated statements of income since the date of acquisition as part of the Structural Systems segment, and its revenues were less than three percent of total company revenues since the date of acquisition. Pro forma results of operations of the BLR acquisition have not been presented as the effect of the BLR acquisition was not material to our financial results.

Note 3. Restructuring Activities

Summary of 2022 Restructuring Plan

In April 2022, management approved and commenced a restructuring plan that will better position us for stronger performance. The restructuring plan will mainly reduce headcount and consolidate facilities. As a result of this restructuring plan, we analyzed the need to write-down inventory and impair long-lived assets, including operating lease right-of-use assets. During the three and six months ended June 29, 2024, we recorded total charges of $2.1 million ($0.9 million of which was recorded as cost of sales) and $3.5 million ($0.9 million of which was recorded as cost of sales), respectively. Cumulative through the six months ended June 29, 2024, we recorded aggregate total charges of $25.0 million ($1.7 million of which was recorded as cost of sales). As of June 29, 2024, we estimate the remaining amount of charges related to this initiative will be $3.0 million to $4.0 million in total pre-tax restructuring charges through early 2025 for employee separation and other facility consolidation related expenses.

In the Electronics Systems segment, we recorded no restructuring charges during the three months ended June 29, 2024. We recorded charges of $0.3 million and $0.2 million during the six months ended June 29, 2024, for severance and benefits that were classified as restructuring charges, and other restructuring charges, respectively. Cumulative through the six months ended June 29, 2024, we recorded total charges for severance and benefits that were classified as restructuring charges, accelerated depreciation of property and equipment that was classified as restructuring charges, charges for inventory write down that was classified as cost of sales, and other restructuring of $9.9 million, $0.3 million, $0.3 million, and $0.3 million, respectively.

In the Structural Systems segment, we recorded $0.8 million and $0.4 million during the three months ended June 29, 2024 for severance and benefits that were classified as restructuring charges and other restructuring charges, respectively. We recorded charges of $1.0 million and $1.1 million during the six months ended June 29, 2024, for severance and benefits that were classified as restructuring charges, and other restructuring charges, respectively. Cumulative through the six months ended June 29, 2024, we recorded total charges for severance and benefits that were classified as restructuring charges, accelerated depreciation of property and equipment/impairment of property and equipment that was classified as restructuring charges, charges for inventory write down that was classified as cost of sales, and other restructuring of $6.9 million, $2.0 million, $1.4 million, and $3.9 million, respectively.

Our restructuring activities during the six months ended June 29, 2024 were as follows (in thousands):

	December 31, 2023		Six Months Ended June 29, 2024								June 29, 2024
	Balance		Charges		Cash Payments		Non-Cash Payments		Change in Estimates		Balance

Note 6. Goodwill

We perform our annual goodwill impairment test as of the first day of the fourth quarter. If certain factors occur, including significant underperformance of our business relative to expected operating results, significant adverse economic and industry trends, a significant decline in our market capitalization for an extended period of time relative to net book value, a decision to divest individual businesses within a reporting unit, or a decision to group individual businesses differently, we may be required to perform an interim impairment test prior to the fourth quarter.

We may use either a qualitative or quantitative approach when testing a reporting unit’s goodwill for impairment. The qualitative approach for potential impairment analysis to determine whether it is more likely than not that the fair value of a reporting unit was less than its carrying amount.

The quantitative approach for potential impairment analysis is performed by comparing the fair value of a reporting unit to its carrying value, including goodwill. Fair value is estimated by management using a combination of the income approach (which is based on a discounted cash flow model) and market approach. Management’s cash flow projections include significant judgments and assumptions, including the amount and timing of expected cash flows, long-term growth rates, and discount rates. The cash flows used in the discounted cash flow model are based on our best estimate of future revenues, gross margins, and adjusted after-tax earnings. If any of these assumptions are incorrect, it will impact the estimated fair value of a reporting unit. The market approach also requires management judgment in selecting comparable business acquisitions and the transaction values observed and its related control premiums.

No material adverse factors/changes have occurred since the fourth quarter of 2023 that would require us to perform another qualitative or quantitative assessment. As such, for the second quarter of 2024, it was also not more likely than not that the fair values of the reporting units were less than their carrying amounts and thus, the respective goodwill amounts were not deemed to be impaired.

In April 2023, we completed the acquisition of BLR. The excess of the purchase price over the aggregate fair values of the net assets was recorded as goodwill. See Note 2 for further information.

The carrying amounts of our goodwill were as follows:

	(Dollars in thousands)

In July 2022, we completed a refinancing of all our existing debt by entering into a new term loan (“2022 Term Loan”) and a new revolving credit facility (“2022 Revolving Credit Facility”). The 2022 Term Loan is a $250.0 million senior secured loan that matures on July 14, 2027. The 2022 Revolving Credit Facility is a $200.0 million senior secured revolving credit facility that matures on July 14, 2027. The 2022 Term Loan and 2022 Revolving Credit Facility, collectively, represent our credit facilities (“2022 Credit Facilities”).

The 2022 Term Loan bears interest, at our option, at a rate equal to either (i) Term Secured Overnight Financing Rate (“Term SOFR”) plus an applicable margin ranging from 1.375% to 2.375% per year or (ii) Base Rate (defined as the highest of [a] Federal Funds Rate plus 0.50%, [b] Bank of America’s prime rate, and [c] Term SOFR plus 1.00%, and if the Base Rate is less than zero percent, it will be deemed zero percent) plus an applicable margin ranging from 0.375% to 1.375% per year, in each case based upon the consolidated total net adjusted leverage ratio. Interest payments are typically paid either on a monthly or quarterly basis, depending on the interest rate selected, on the last business day each month or quarter. In addition, the 2022 Term Loan requires quarterly amortization payments of 0.625% during year one and year two, 1.250% during year three and year four, and 1.875% during year five of the original outstanding principal balance of the 2022 Term Loan amount, on the last business day each quarter. The required quarterly amortization payments began in the fourth quarter of 2022.

The 2022 Revolving Credit Facility bears interest, at our option, at a rate equal to either (i) Term SOFR plus an applicable margin ranging from 1.375% to 2.375% per year or (ii) Base Rate (defined as the highest of [a] Federal Funds Rate plus 0.50%, [b] Bank of America’s prime rate, and [c] Term SOFR plus 1.00%, and if the Base Rate is less than zero percent, it will be deemed zero percent) plus an applicable margin ranging from 0.375% to 1.375% per year, in each case based upon the consolidated total net adjusted leverage ratio. Interest payments are typically paid on a monthly or quarterly basis, depending on the interest rate selected, on the last business day each month or quarter. The undrawn portion of the commitment of the 2022 Revolving Credit Facility is subject to a commitment fee ranging from 0.175% to 0.275%, based upon the consolidated total net adjusted leverage ratio, typically paid on a quarterly basis, on the last business day each quarter. However, the 2022 Revolving Credit Facility does not require any principal installment payments.

In conjunction with the closing of the 2022 Credit Facilities, we utilized the entire $250.0 million of proceeds from the 2022 Term Loan plus our existing cash on hand to pay off our entire debt balance outstanding of $254.2 million under our prior credit facilities.

20

For each of the three months ended June 29, 2024 and July 1, 2023, we made the required quarterly amortization payments on the 2022 Term Loan of $1.6 million. For each of the six months ended June 29, 2024 and July 1, 2023, we made the required amortization payments on the 2022 Term Loan totaling $3.1 million.

As of June 29, 2024, we had $176.0 million of unused borrowing capacity under the 2022 Revolving Credit Facility, after deducting $0.2 million for standby letters of credit.

As of June 29, 2024, we were in compliance with all covenants required under the 2022 Credit Facilities.

The 2022 Term Loan was considered a modification of debt for some lenders and an extinguishment of debt for other lenders, and thus, a loss of $0.2 million was recorded related to the extinguishment. In addition, the new fees incurred of $0.8 million were capitalized and will be amortized over the life of the 2022 Term Loan. Further, the remaining debt issuance costs related to the prior term loans of $1.0 million as of the modification date will be amortized over the life of the 2022 Term Loan, using the effective interest method.

The 2022 Revolving Credit Facility that replaced the prior revolving credit facility was considered a modification of debt except for the portion related to the creditor that is no longer a part of the 2022 Revolving Credit Facility and, in which case, it was considered an extinguishment of debt. As a result, we expensed the portion of the unamortized debt issuance costs related to the prior revolving credit facility that was considered an extinguishment of debt of $0.1 million. In addition, the new fees incurred of $1.7 million as part of the 2022 Revolving Credit Facility were capitalized and will be amortized over the life of the 2022 Revolving Credit Facility. Further, the remaining debt issuance costs related to the prior revolving credit facility of $0.8 million as of the modification date will also be amortized over the life of the 2022 Revolving Credit Facility.

The 2022 Credit Facilities were entered into by us (“Parent Company”) and guaranteed by all of our domestic subsidiaries, other than two subsidiaries that were considered minor (“Subsidiary Guarantors”). The Subsidiary Guarantors jointly and severally guarantee the 2022 Credit Facilities. The Parent Company has no independent assets or operations, and therefore, no consolidating financial information for the Parent Company and its subsidiaries is presented.

In April 2023, we completed the acquisition of BLR. The initial purchase price for BLR was $115.0 million, net of cash acquired, all payable in cash. We paid a gross aggregate of $117.0 million in cash upon the closing of the transaction. We utilized the 2022 Revolving Credit Facility to complete the acquisition. See Note 2 for further information.

In May 2023, we completed a public offering of our common stock resulting in net proceeds of $85.1 million. We utilized the net proceeds plus cash on hand to pay down $85.2 million on the 2022 Revolving Credit Facility. See Note 9 for further information.

In November 2021, we entered into derivative contracts, U.S. dollar-one month LIBOR forward interest rate swaps designated as cash flow hedges, all with an effective date of January 1, 2024, for an aggregate total notional amount of $150.0 million, weighted average fixed rate of 1.8%, and all terminating on January 1, 2031 (“Forward Interest Rate Swaps”). The Forward Interest Rate Swaps mature on a monthly basis, with fixed amount payer payment dates on the first day of each calendar month, commencing on February 1, 2024 through January 1, 2031. The Forward Interest Rate Swaps were deemed to be highly effective upon entering into the derivative contracts, and thus, hedge accounting treatment was utilized. Since the Amended Forward Interest Rate Swaps (as defined below) were not effective until January 1, 2024, we only recorded the changes in fair value of the derivative instruments that were highly effective and that were designated and qualified as cash flow hedges in other comprehensive income through December 31, 2023. See Note 1 and Note 4 for further information.

In July 2022, as a result of completing a refinancing of our existing debt, we were required to complete an amendment of the Forward Interest Rate Swaps (“Amended Forward Interest Rate Swaps”). The Forward Interest Rate Swaps were based on U.S. dollar-one month LIBOR and were amended to be based on one month Term SOFR as borrowings using LIBOR were no longer available under the 2022 Credit Facilities. Since this was an amendment of just the reference rate as a result of the cessation of LIBOR, utilizing the guidance under ASU 2020-04, we determined the Amended Forward Interest Rate Swaps as of the amendment date to continue to be highly effective. The Amended Forward Interest Rate Swaps weighted average fixed rate is 1.7%, as a result of the difference between U.S. dollar-one month LIBOR and one month Term SOFR.

Note 9. Shareholders’ Equity

In May 2023, we completed a public offering of 2.3 million shares of our common stock at $40.00 per share, for gross proceeds of $92.0 million. The common stock offering was made under our effective shelf registration statement. We incurred aggregate total out of pocket stock offering related fees of $6.9 million, resulting in net proceeds of $85.1 million. As such, we recorded an increase to common stock at par value of less than $0.1 million with the remaining amount as an increase to additional paid-in capital of $85.1 million. The net proceeds of the public stock offering along with cash on hand were used to pay down $85.2 million on the 2022 Revolving Credit Facility that was drawn on and utilized to complete the acquisition of BLR. See Note 2 and Note 8 for further information.

Note 10. Indemnifications

We have made guarantees and indemnities under which we may be required to make payments to a guaranteed or indemnified party, in relation to certain transactions, including revenue transactions in the ordinary course of business. Additionally, we indemnify our directors and officers to the maximum extent permitted under the laws of the State of Delaware and have a directors and officers insurance policy that may reduce our exposure in certain circumstances and may enable us to recover a portion of future amounts that may be payable, if any. Moreover, in connection with certain performance center leases, we have indemnified our lessors for certain claims arising from the performance center or the lease.

The duration of the guarantees and indemnities varies and, in many cases, is indefinite but subject to applicable statutes of limitations. The majority of guarantees and indemnities do not provide any limitations on the maximum potential future payments we could be obligated to make. Historically, payments related to these guarantees and indemnities have been immaterial. We estimate the fair value of our indemnification obligations as insignificant based on this history and insurance coverage and have, therefore, not recorded any liability for these guarantees and indemnities in the accompanying condensed consolidated balance sheets.

Note 11. Income Taxes

The provision for income taxes is determined using an estimated annual effective tax rate, which is generally less than the U.S. Federal statutory rate, primarily due to research and development (“R&D”) tax credits. Our effective tax rate may be subject to fluctuations during the year as new information is obtained, which may affect the assumptions used to estimate the annual effective tax rate, including factors such as expected utilization of R&D tax credits, valuation allowances against deferred tax assets, recognition or derecognition of tax benefits related to uncertain tax positions, and changes in or the interpretation of tax laws in jurisdictions where we conduct business. Also, excess tax benefits and tax detriments related to our equity compensation recognized in the condensed consolidated income statement could result in fluctuations in our effective tax rate period-over-period depending on the volatility of our stock price, number of restricted or performance stock units that vests, and stock options exercised during the period. We recognize deferred tax assets and liabilities, using enacted tax rates, for temporary differences between the financial reporting basis and the tax basis of our assets and liabilities along with net operating loss and tax credit carryovers.

We record a valuation allowance against our deferred tax assets to reduce the net carrying value to an amount that we believe is more likely than not to be realized. When we establish or reduce our valuation allowances against our deferred tax assets, the provision for income taxes will increase or decrease, respectively, in the period when that determination is made.

We recorded income tax expense of $2.2 million for the three months ended June 29, 2024 compared to $1.0 million for the three months ended July 1, 2023. The increase in income tax expense for the second quarter of 2024 compared to the second quarter of 2023 was primarily due to higher pre-tax income and higher income tax expense related to non-deductible book compensation expenses in the second quarter of 2024 compared to the second quarter of 2023. The increase in income tax expense was partially offset by higher income tax benefits related to the U.S. Federal research and development credit recognized in the second quarter of 2024 compared to the second quarter of 2023.

We recorded income tax expense of $4.1 million for the six months ended June 29, 2024 compared to $1.8 million for the six months ended July 1, 2023. The increase in income tax expense for the six months ended June 29, 2024 compared to the six months ended July 1, 2023 was primarily due to higher pre-tax income and higher income tax expense related to non-deductible book compensation expenses in the six months ended June 29, 2024 compared to the six months ended July 1, 2023. The increase in income tax expense was partially offset by higher income tax benefits related to the U.S. Federal research and development credit recognized in the six months ended June 29, 2024 compared to the six months ended July 1, 2023.

Our total amount of unrecognized tax benefits was $4.8 million and $4.5 million as of June 29, 2024 and December 31, 2023, respectively. If recognized, $3.0 million would affect the effective tax rate. We record interest and penalty charges, if any, related to uncertain tax positions as a component of tax expense and unrecognized tax benefits. The amounts accrued for interest and penalty charges as of June 29, 2024 and December 31, 2023 were not significant. As a result of statute of limitations set to expire in the fourth quarter of 2024, we expect decreases to our unrecognized tax benefits of approximately $1.0 million in the next twelve months.

We file U.S. Federal and state income tax returns. We are subject to examination by the Internal Revenue Service (“IRS”) for tax years after 2019 and by state taxing authorities for tax years after 2018. While we are no longer subject to examination prior to those periods, carryforwards generated prior to those periods may still be adjusted upon examination by the IRS or state taxing authorities if they either have been or will be used in a subsequent period. We believe we have adequately accrued for tax deficiencies or reductions in tax benefits, if any, that could result from the examination and all open audit years.

Note 12. Commitments and Contingencies

California’s Wage and Hour Laws Complaint

In December 2020, a representative action under California’s Private Attorneys General Act was filed against us in the Superior Court for the State of California, County of San Bernardino. We received service of process of this complaint in January 2021. The complaint alleged violations of California’s wage and hour laws relating to our current and former employees and sought attorney’s fees and penalties. We vigorously refuted and defended against these claims and reached a tentative settlement of $0.8 million during the fourth quarter 2021, which was subject to court approval. Thus, we recorded accrued liabilities of $0.8 million as of December 31, 2021. During the second quarter of 2022, additional factual information was identified resulting in an increase in the amount of the tentative settlement to $0.9 million. Therefore, we recorded an additional accrued liabilities of $0.1 million for a total accrued liabilities amount of $0.9 million as of the end of the second quarter of 2022 which remained unchanged as of December 31, 2022 as we were awaiting final court approval of this settlement. Subsequent to final court approval and paying of the $0.9 million in January 2023, during the third quarter of 2023 and upon plaintiff's motion, the court re-opened the settlement agreement to determine whether the class list captured all affected employees. We are appealing this decision and intend to defend our position vigorously. Any amount of additional liability is still undetermined pending the appeal and as such, there is no amount of loss that is probable and reasonably estimable at this time. Thus, no additional accrual was recorded during the three and six months ended June 29, 2024.

Groundwater

Structural Systems has been directed by California environmental agencies to investigate and take corrective action for groundwater contamination at our facilities located in El Mirage and Monrovia, California. Based on currently available information, we have established an accrual for its estimated liability for such investigation and corrective action of $1.5 million at both June 29, 2024 and December 31, 2023, which is reflected in other long-term liabilities on our condensed consolidated balance sheets.

Waste Disposal

Structural Systems also faces liability as a potentially responsible party for hazardous waste disposed at landfills located in Casmalia and West Covina, California. Structural Systems and other companies and government entities have entered into consent decrees with respect to these landfills with the United States Environmental Protection Agency and/or California environmental agencies under which certain investigation, remediation and maintenance activities are being performed. Based on currently available information, we preliminarily estimate that the range of our future liabilities in connection with the landfill located in West Covina, California is between $0.4 million and $3.1 million. We have established an accrual for the estimated liability in connection with the West Covina landfill of $0.4 million as of both June 29, 2024 and December 31, 2023, which is reflected in other long-term liabilities on our condensed consolidated balance sheets. Our ultimate liability in connection with these matters will depend upon a number of factors, including changes in existing laws and regulations, the design and cost of construction, operation and maintenance activities, and the allocation of liability among potentially responsible parties.

Guaymas Performance Center Fire

In June 2020, a fire severely damaged our performance center in Guaymas, Mexico, which is part of our Structural Systems segment. There were no injuries; however, property and equipment, inventories, and tooling in this leased facility were damaged. Our Guaymas performance center, comprised of two buildings with an aggregate total of 62,000 square feet, was severely damaged. The loss of production from the Guaymas performance center was absorbed by our other existing performance centers; however, we have reestablished our operations and are in the process of certification with various customers and ramping up our manufacturing capabilities in a different leased facility with 117,000 square feet in Guaymas. A neighboring, non-related manufacturing facility, also suffered fire damage during the same time as the fire that severely damaged our Guaymas performance center, and in November 2023, the occupant of the neighboring facility filed suit against us in U.S. District Court for the Central District of California seeking unspecified amounts for damages relating to the fire. In addition, subsequent to the quarter end, we received a subrogation demand from our landlord’s insurer, which we are currently evaluating. We intend to defend these matters vigorously and believe we have substantial defenses in relation to these claims. As responsibility for the fire is still undetermined, there is no amount of loss that is probable and reasonably estimable at this time. If we are ultimately deemed to be responsible or party responsible, it is possible we could incur a loss in excess of our insurance coverage limits, which could be material to our cash flow, liquidity, or financial results.

Our insurance covers damage, up to a capped amount, to the facility, equipment, unfinished inventory, and other assets at replacement cost, finished goods inventory at selling price, as well as business interruption, third party property damage, and recovery related expenses caused by the fire, less our per claim deductible. The anticipated insurance recoveries related to losses and incremental costs incurred are recognized when receipt is probable. The anticipated insurance recoveries in excess of net book value of the damaged operating assets and business interruption are not recorded until all contingencies related to our

23

claim have been resolved.

The insurance claim for damages to our operating assets and business interruption was deemed final and closed by our insurance company during the three months ended July 1, 2023. Thus, the final $3.8 million of insurance recoveries were also received and recorded as other income during the three months ended July 1, 2023. In addition, the remaining general insurance recoveries that were received in 2020 of $3.9 million, but recognition was deferred until all the gain contingencies were resolved, such gain contingencies were deemed resolved and thus, recorded as other income during the three months ended July 1, 2023. Cumulatively, as of July 1, 2023, we received insurance recoveries in aggregate total of $23.7 million, with $7.5 million for business interruption and $16.2 million for damages to property and equipment, inventories, and tooling. Further, all insurance recovery amounts received related to this claim have been recognized up to the amount of net book value loss and presented within the same financial statement line item in the condensed consolidated statements of income resulting in no net impact, with the remaining amounts recognized as other income in our condensed consolidated statements of income when the contingencies were deemed resolved.

Other Structural Systems Performance Center Fire

In April 2023, a fire damaged a relatively small portion of one of our performance centers in our Structural Systems reporting segment. There were no injuries; however, subsequent to the fire, we determined that some property and equipment in this company-owned facility were damaged. Our insurance covers damage, up to a capped amount, to the property and equipment at replacement cost, as well as business interruption and recovery related expenses caused by the fire, less our per claim deductible. There was a loss of production in this damaged portion of the performance center for a short period of time, but the incident did not otherwise result in significant disruption to customer delivery schedules. Production in this damaged portion resumed later that same quarter. As such, during the three months ended July 1, 2023, we wrote off property and equipment with an aggregate total net book value of $0.2 million. Also during the three months ended July 1, 2023, we received insurance recoveries of $0.3 million (which was net of our deductible of $0.1 million) and thus, such insurance recoveries were also presented within the same financial statement line item in the condensed consolidated statements of income resulting in no net impact. The amount of the insurance recoveries received in excess of the loss on operating assets was deemed a contingent gain, and since the gain contingencies were deemed resolved, the $0.1 million was also recorded as other income during the three months ended July 1, 2023. Finally, during the three months ended December 31, 2023, the insurance claim was deemed final and closed by our insurance company and we received a final payment of $0.3 million, which was recorded as other income.

Real Estate Obligations

Real estate obligations, which include legally binding minimum lease payments for an executed lease that had not yet commenced, were $5.8 million as of June 29, 2024, and will be paid over the lease term of 10 years.

In the normal course of business, Ducommun and its subsidiaries are defendants in certain other litigation, claims and inquiries, including matters relating to environmental laws. In addition, Ducommun makes various commitments and incurs contingent liabilities in the ordinary course of business. While it is not feasible to predict the outcome of these matters, Ducommun does not presently expect that any sum it may be required to pay in connection with these matters would have a material adverse effect on its condensed consolidated financial position, results of operations or cash flows.

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

Overview

Ducommun Incorporated (“Ducommun,” “the Company,” “we,” “us” or “our”) is a leading global provider of engineering and manufacturing services for high-performance products and high-cost-of failure applications used primarily in the aerospace and defense (“A&D”), industrial, medical and other industries (collectively, “Industrial”). We differentiate ourselves as a full-service solution-based provider, offering a wide range of value-added products and services in our primary businesses of electronics, structures and integrated solutions. We operate through two primary business segments: Electronic Systems and Structural Systems, each of which is a reportable segment.

In its 2023 Annual Report on Form 10-K, The Boeing Company (“Boeing”) indicated that in 2023, global air traffic largely recovered to 2019 levels with domestic travel continuing to be the most robust and international travel has mostly recovered. For 2024, while both major large aircraft manufacturers, Boeing and Airbus SE, have announced either similar or increases in build rates compared to 2023, the ramp up to date has been slower than initially expected and below pre-pandemic levels. In addition, Boeing, one of our largest customers, was notified by the Federal Aviation Administration (“FAA”) in early January 2024 that the FAA had initiated an investigation into Boeing’s quality control system. This notification was followed by the FAA announcing actions to increase its oversight of Boeing as well as not approving production rate increases or additional production lines for the 737 MAX until it is satisfied that Boeing is in full compliance with required quality control procedures. In July 2024, Boeing also pleaded guilty to conspiracy fraud charges, which may result in additional external oversight on its manufacturing and quality control process. Since Boeing is one of our largest customers, if Boeing is unable to meet the full compliance of the FAA’s required quality control procedures, it could have a material adverse impact on our business, results of operations and financial condition.

Second quarter 2024 recap:

•Net revenues of $197.0 million

•Net income of $7.7 million, or 3.9% of net revenues, or $0.52 per diluted share

•Adjusted EBITDA of $30.0 million, or 15.2% of net revenues

Net revenues for the three months ended June 29, 2024 were $197.0 million, compared to $187.3 million for the three months ended July 1, 2023. The year-over-year increase in our key end-use markets were primarily due to the following:

•$9.9 million higher revenues in our commercial aerospace end-use markets due to higher production on selected single-aisle and twin-aisle aircraft, buffer stock build for the Monrovia performance center closure, and growth in regional and business aircraft platforms, partially offset by lower revenues from in-flight entertainment; and

•$3.2 million higher revenues in our military and space end-use markets due to higher rates on rotary-wing aircraft and naval platforms, partially offset by lower rates on fixed-wing aircraft platforms.

In addition, revenues for our industrial end-use markets for the three months ended June 29, 2024 decreased $3.4 million compared to the three months ended July 1, 2023 mainly due to our selectively pruning non-core business.

Net revenues for the six months ended June 29, 2024 were $387.8 million, compared to $368.5 million for the six months ended July 1, 2023. The year-over-year increase in our key end-use markets were primarily due to the following:

•$18.0 million higher revenues in our commercial aerospace end-use markets due to higher rates on select single-aisle and twin-aisle aircraft, buffer stock for the Monrovia performance center closure, growth in regional and business aircraft platforms, partially offset by lower revenues from in-flight entertainment; and

•$4.4 million higher revenues in our military and space end-use markets due to higher rates on naval and submarine platforms, naval and rotary-wing aircraft platforms, and various radar platforms, partially offset by lower rates on fixed-wing aircraft platforms and various missile platforms.

In addition, revenues for our industrial end-use markets for the six months ended June 29, 2024 decreased $3.1 million compared to the six months ended July 1, 2023 mainly due to our selectively pruning non-core business.

Net Revenues by Major Customers

A significant portion of our net revenues are from our top ten customers as follows:

	Three Months Ended				Six Months Ended
	June 29, 2024		July 1, 2023		June 29, 2024		July 1, 2023
Boeing Company	9.1	%	8.0	%	8.6	%	7.8	%

Spirit AeroSystems Holdings, Inc.	6.6	%	5.7	%	6.3	%	6.4	%
Viasat, Inc.	3.2	%	4.9	%	3.5	%	5.2	%
Total top ten customers (1)	56.8	%	56.5	%	55.6	%	57.4	%

(1)Includes The Boeing Company (“Boeing”), Lockheed Martin Corporation (“Lockheed”), Northrop Grumman Corporation (“Northrop”), RTX Corporation (“RTX”), Spirit AeroSystems Holdings, Inc. (“Spirit”), and Viasat, Inc. (“Viasat”) for the three and six months ended June 29, 2024 and July 1, 2023.

Boeing, Lockheed, Northrop, RTX, Spirit, and Viasat represented the following percentages of total accounts receivable:

	June 29, 2024		December 31, 2023
Boeing	12.4	%	7.5	%
Lockheed	3.2	%	1.3	%
Northrop	4.6	%	2.5	%
RTX	14.4	%	16.4	%
Spirit	3.1	%	4.2	%
Viasat	3.5	%	8.3	%

The net revenues and accounts receivable from Boeing, Lockheed, Northrop, RTX, Spirit, and Viasat are diversified over a number of commercial, military and space programs and were generated by both operating segments.

Gross Profit

Gross profit consists of net revenues less cost of sales. Cost of sales includes the cost of production of finished products and other expenses related to inventory management, manufacturing quality, and order fulfillment. Gross profit as a percentage of net revenues increased year-over-year with the three months ended June 29, 2024 of 26.0%, compared to the three months ended July 1, 2023 of 21.4% primarily due to higher manufacturing volume and favorable product mix, partially offset by higher other manufacturing costs.

Gross profit as a percentage of net revenues increased year-over-year with the six months ended June 29, 2024 of 25.3%, compared to the six months ended July 1, 2023 of 20.9% primarily due to higher manufacturing volume and favorable product mix, partially offset by higher other manufacturing costs.

Selling, General and Administrative (“SG&A”) Expenses

SG&A expenses increased $5.7 million year-over-year in the three months ended June 29, 2024 compared to the three months ended July 1, 2023 primarily due to higher professional services fees of $2.9 million, of which $1.4 million was related to the unsolicited non-binding offer to acquire all common stock outstanding of Ducommun Incorporated, and BLR SG&A expenses of $1.3 million which did not exist until the acquisition of BLR was completed at the end of April 2023.

SG&A expenses increased $12.4 million year-over-year in the six months ended June 29, 2024 compared to the six months ended July 1, 2023 primarily due to BLR SG&A expenses of $6.8 million which did not exist until the acquisition of BLR was completed at the end of April 2023, higher professional services fees of $2.2 million, of which $1.4 million was related to the unsolicited non-binding offer to acquire all common stock outstanding of Ducommun Incorporated, and higher compensation and benefits expense of $1.8 million.

Restructuring Charges

Restructuring charges decreased $2.7 million and $5.5 million (including $0.9 million recorded as cost of sales in both periods) year-over-year in the three and six months ended June 29, 2024, compared to the three and six months ended July 1, 2023, respectively,

30

primarily due to the winding down of the previously disclosed restructuring plan that was approved and commenced in April 2022. See Note 3 for further information.

Interest Expense

Interest expense decreased $1.8 million and $2.1 million year-over-year in the three and six months ended June 29, 2024, compared to the three and six months ended July 1, 2023, respectively, primarily due to the interest rate swaps that became effective as of January 1, 2024, along with a lower debt balance.

Income Tax Expense

We recorded income tax expense of $2.2 million for the three months ended June 29, 2024 compared to $1.0 million for the three months ended July 1, 2023. The increase in income tax expense for the second quarter of 2024 compared to the second quarter of 2023 was primarily due to higher pre-tax income and higher income tax expense related to non-deductible book compensation expenses in the second quarter of 2024 compared to the second quarter of 2023. The increase in income tax expense was partially offset by higher income tax benefits related to the U.S. Federal research and development credit recognized in the second quarter of 2024 compared to the second quarter of 2023.

We recorded income tax expense of $4.1 million for the six months ended June 29, 2024 compared to $1.8 million for the six months ended July 1, 2023. The increase in income tax expense for the six months ended June 29, 2024 compared to the six months ended July 1, 2023 was primarily due to higher pre-tax income and higher income tax expense related to non-deductible book compensation expenses in the six months ended June 29, 2024 compared to the six months ended July 1, 2023. The increase in income tax expense was partially offset by higher income tax benefits related to the U.S. Federal research and development credit recognized in the six months ended June 29, 2024 compared to the six months ended July 1, 2023.

Our total amount of unrecognized tax benefits was $4.8 million and $4.5 million as of June 29, 2024 and December 31, 2023, respectively. If recognized, $3.0 million would affect the effective tax rate. We record interest and penalty charges, if any, related to uncertain tax positions as a component of tax expense and unrecognized tax benefits. The amounts accrued for interest and penalty charges as of June 29, 2024 and December 31, 2023 were not significant. As a result of statute of limitations set to expire in the fourth quarter of 2024, we expect decreases to our unrecognized tax benefits of approximately $1.0 million in the next twelve months.

We file U.S. Federal and state income tax returns. We are subject to examination by the Internal Revenue Service (“IRS”) for tax years after 2019 and by state taxing authorities for tax years after 2018. While we are no longer subject to examination prior to those periods, carryforwards generated prior to those periods may still be adjusted upon examination by the IRS or state taxing authorities if they either have been or will be used in a subsequent period. We believe we have adequately accrued for tax deficiencies or reductions in tax benefits, if any, that could result from the examination and all open audit years.

Net Income and Earnings per Share

Net income and earnings per share for the three months ended June 29, 2024 were $7.7 million, or 3.9% of revenues, or $0.52 per diluted share, compared to $2.4 million, or 1.3% of revenues, or $0.17 per diluted share, for the three months ended July 1, 2023. The increase in net income for the three months ended June 29, 2024 compared to the three months ended July 1, 2023 was primarily due to higher gross profit of $11.1 million and lower restructuring charges of $2.7 million ($0.9 million was recorded as cost of sales), partially offset by higher SG&A expenses of $5.7 million and lower other income of $4.1 million. A portion of the higher SG&A expenses were due to BLR SG&A expenses of $1.3 million which did not exist until the end of April 2023.

Net income and earnings per share for the six months ended June 29, 2024 were $14.6 million, or 3.8% of revenues, or $0.97 per diluted share, compared to $7.6 million, or 2.1% of revenues, or $0.58 per diluted share, for the six months ended July 1, 2023. The increase in net income for the six months ended June 29, 2024 compared to the six months ended July 1, 2023 was primarily due to higher gross profit of $21.3 million and lower restructuring charges of $5.5 million ($0.9 million was recorded as cost of sales), partially offset by higher SG&A expenses of $12.4 million and lower other income of $7.9 million. A portion of the higher SG&A expenses were due to BLR SG&A expenses of $6.8 million which did not exist until the end of April 2023.

The Structural Systems segment operating income in the three months ended June 29, 2024 compared to the three months ended July 1, 2023 increased $5.2 million primarily due to higher manufacturing volume, favorable product mix, and lower Guaymas fire related expenses.

The Structural Systems segment operating income in the six months ended June 29, 2024 compared to the six months ended July 1, 2023 increased $3.3 million primarily due to higher manufacturing volume, favorable product mix, lower Guaymas fire related expenses, and lower restructuring charges, partially offset by higher costs associated with the wind down of our Monrovia performance center.

In April 2023, we acquired 100.0% of BLR Aerospace L.L.C. (“BLR”). The initial purchase price for BLR was $115.0 million, net of cash acquired, all payable in cash. We paid a gross aggregate of $117.0 million in cash upon the closing of the transaction. BLR’s results of operations have been included in our condensed consolidated statements of income since the date of acquisition and is a part of the Structural Systems segment. See Note 2 to our condensed consolidated financial statements included in Part I, Item 1 of this Form 10-Q for further information.

In June 2020, a fire severely damaged our performance center in Guaymas, Mexico. We have insurance coverage and up to a capped amount, expect these items will be covered, less our deductible. The full financial impact cannot be estimated at this time as we are currently working with our insurance carriers to determine the cause of the fire. The loss of production from the Guaymas performance center was absorbed by our other existing performance centers, however, we have reestablished and are in the process of certification with various customers and ramping up our manufacturing capabilities in a different leased facility in Guaymas. A neighboring, non-related manufacturing facility, also suffered fire damage during the same time as the fire that severely damaged our Guaymas performance center. In addition, subsequent to the quarter end, we received a subrogation demand from our landlord’s insurer, which we are currently evaluating. As responsibility for the fire is still undetermined, there is no amount of loss that is probable and reasonably estimable at this time. If we are ultimately deemed to be responsible or partly responsible, it is possible we could incur a loss in excess of our insurance coverage limits, which could be material to our cash flow, liquidity, or financial results. See Note 12 to our condensed consolidated financial statements included in Part I, Item 1 of this Form 10-Q.

In April 2023, a fire damaged a relatively small portion of one of our performance centers in our Structural Systems reporting segment. Our insurance covers damage, up to a capped amount, to the property and equipment at replacement cost, as well as business interruption and recovery related expenses caused by the fire, less our per claim deductible. There was a loss of production in this damaged portion of the performance center for a short period of time, but the incident did not otherwise result in significant disruption to customer delivery schedules. Production in this damaged portion resumed during the three months ended July 1, 2023. See Note 12 to our condensed consolidated financial statements included in Part I, Item 1 of this Form 10-Q.

Corporate General and Administrative (“CG&A”) Expenses

CG&A expenses increased $3.5 million for the three months ended June 29, 2024 compared to the three months ended July 1, 2023 primarily due to higher professional services fees of $2.9 million, of which $1.4 million was related to the unsolicited non-binding offer to acquire all common stock outstanding of Ducommun Incorporated.

CG&A expenses increased $4.4 million for the six months ended June 29, 2024 compared to the six months ended July 1, 2023 primarily due to higher professional services fees of $2.1 million, of which $1.4 million was related to the unsolicited non-binding offer to acquire all common stock outstanding of Ducommun Incorporated, and higher compensation and benefits expense of $1.5 million.

Non-GAAP Financial Measures

Adjusted earnings before interest, taxes, depreciation, amortization, stock-based compensation expense, restructuring charges, professional fees related to unsolicited non-binding acquisition offer, Guaymas fire related expenses, insurance recoveries related to loss on operating assets, and inventory purchase accounting adjustments (“Adjusted EBITDA”) were $30.0 million and $26.1 million for the three months ended June 29, 2024 and July 1, 2023, respectively.

When viewed with our financial results prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and accompanying reconciliations, we believe Adjusted EBITDA provides additional useful information that clarifies and enhances the understanding of the factors and trends affecting our past performance and future prospects. We define this measure, explain how it is calculated and provide a reconciliation of this measure to the most comparable GAAP measure in the table below. Adjusted EBITDA and the related financial ratios, as presented in this Quarterly Report on Form 10-Q (“Form 10-Q”), are supplemental measures of our performance that are not required by, or presented in accordance with, GAAP. They are not a measurement of our financial performance under GAAP and should not be considered as alternatives to net income or any other performance measures derived in accordance with GAAP, or as an alternative to net cash provided by operating activities as measures of our liquidity. The presentation of these measures should not be interpreted to mean that our future results will be unaffected by unusual or nonrecurring items.

We use Adjusted EBITDA as a non-GAAP operating performance measure internally as a complementary financial measure to evaluate the performance and trends of our businesses. We present Adjusted EBITDA and the related financial ratios, as applicable, because we believe that measures such as these provide useful information with respect to our ability to meet our operating commitments.

Adjusted EBITDA has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our results as reported under GAAP. Some of these limitations include:

•It does not reflect our cash expenditures, future requirements for capital expenditures or contractual commitments;

•It does not reflect changes in, or cash requirements for, our working capital needs;

•It does not reflect the significant interest expense or the cash requirements necessary to service interest or principal payments on our debt;

•Although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and Adjusted EBITDA does not reflect any cash requirements for such replacements;

•It is not adjusted for all non-cash income or expense items that are reflected in our statements of cash flows;

•It does not reflect the impact on earnings of charges resulting from matters unrelated to our ongoing operations; and

•Other companies in our industry may calculate Adjusted EBITDA differently from us, limiting its usefulness as a comparative measure.

As a result of these limitations, Adjusted EBITDA and the related financial ratios should not be considered as measures of discretionary cash available to us to invest in the growth of our business or as a measure of cash that will be available to us to meet our obligations. You should compensate for these limitations by relying primarily on our GAAP results and using Adjusted EBITDA only as supplemental information. See our condensed consolidated financial statements contained in this Form 10-Q.

Even with the limitations above, we believe that Adjusted EBITDA is useful to an investor in evaluating our results of operations as this measure:

•Is widely used by investors to measure a company’s operating performance without regard to items excluded from the calculation of such terms, which can vary substantially from company to company depending upon accounting methods and book value of assets, capital structure and the method by which assets were acquired, among other factors;

•Helps investors to evaluate and compare the results of our operations from period to period by removing the effect of our capital structure from our operating performance; and

•Is used by our management team for various other purposes in presentations to our Board of Directors as a basis for strategic planning and forecasting.

The following financial items have been added back to or subtracted from our net income when calculating Adjusted EBITDA:

•Interest expense may be useful to investors for determining current cash flow;

•Income tax expense may be useful to investors because it represents the taxes which may be payable for the period and the change in deferred taxes during the period, and may reduce cash flow available for use in our business;

35

•Depreciation may be useful to investors because it generally represents the wear and tear on our property and equipment used in our operations;

•Amortization expense may be useful to investors because it represents the estimated attrition of our acquired customer base and the diminishing value of product rights;

•Stock-based compensation may be useful to our investors for determining current cash flow;

•Restructuring charges may be useful to our investors in evaluating our core operating performance;

•Professional fees related to unsolicited non-binding acquisition offer may be useful to our investors in evaluating our core operating performance;

•Guaymas fire related expenses may be useful to our investors in evaluating our core operating performance;

•Other fire related expenses may be useful to our investors in evaluating our core operating performance;

•Insurance recoveries related to loss on operating assets (property and equipment, inventories, and other assets) may be useful to our investors in evaluating our core operating performance;

•Insurance recoveries related to business interruption may be useful to our investors in evaluating our core operating performance; and

•Purchase accounting inventory step-ups may be useful to our investors as they do not necessarily reflect the current or on-going cash charges related to our core operating performance.

Reconciliations of net income to Adjusted EBITDA and the presentation of Adjusted EBITDA as a percentage of net revenues were as follows:

Backlog

We define backlog as customer placed purchase orders (“POs”) and long-term agreements (“LTAs”) with firm fixed price and expected delivery dates of 24 months or less. The majority of the LTAs do not meet the definition of a contract under ASC 606, and thus, the backlog amount disclosed below is greater than the remaining performance obligations amount disclosed in Note 1 to our condensed consolidated financial statements included in Part I, Item 1 of this Form 10-Q. Backlog is subject to delivery delays or program cancellations, which are beyond our control. Backlog is affected by timing differences in the placement of customer orders and tends to be concentrated in several programs to a greater extent than our net revenues. Backlog in industrial markets tends to be of a shorter duration and is generally fulfilled within a three month period. As a result of these factors, trends in our overall level of backlog may not be indicative of trends in our future net revenues.

The increase in backlog was primarily in the military and space end-use markets and commercial aerospace end-use markets. $668.0 million of total backlog is expected to be delivered over the next 12 months. The following table summarizes our backlog as of June 29, 2024 and December 31, 2023:

	(Dollars in thousands)
	Change		June 29, 2024		December 31, 2023

Liquidity and Capital Resources

Available Liquidity

Total debt, the weighted-average interest rate, cash and cash equivalents and available credit facilities were as follows:

	(Dollars in millions)
	June 29,			December 31,
	2024			2023
Total debt, including long-term portion	$	262.9		$	266.0
Weighted-average interest rate on debt	7.36		%	7.53		%
Term Loans interest rate	7.12		%	6.93		%
Cash and cash equivalents	$	29.4		$	42.9
Unused Revolving Credit Facility	$	176.0		$	176.0

In July 2022, we completed a refinancing of all our existing debt by entering into a new term loan (“2022 Term Loan”) and a new revolving credit facility (“2022 Revolving Credit Facility”). The 2022 Term Loan is a $250.0 million senior secured loan that matures on July 14, 2027. The 2022 Revolving Credit Facility is a $200.0 million senior secured revolving credit facility that matures on July 14, 2027. The 2022 Term Loan and 2022 Revolving Credit Facility, collectively, represent our new credit facilities (“2022 Credit Facilities”). In conjunction with the closing of the 2022 Credit Facilities, we utilized the entire $250.0 million of proceeds from the 2022 Term Loan plus our existing cash on hand to pay off our entire debt balance outstanding of $254.2 million under our prior credit facilities. At the same leverage ratio, the interest rate spread in the 2022 Credit Facilities is lower than the interest rate spread under our prior credit facilities. Interest payments are typically paid either on a monthly or quarterly basis, depending on the interest rate selected, on the last business day each month or quarter. In addition, the 2022 Term Loan requires quarterly amortization payments of 0.625% during year one and year two, 1.250% during year three and year four, and 1.875% during year five of the original outstanding principal balance of the 2022 Term Loan amount, on the last business day each quarter. Further, the undrawn portion of the commitment of the 2022 Revolving Credit Facility is subject to a commitment fee ranging from 0.175% to 0.275%, based upon the consolidated total net adjusted leverage ratio, typically paid on a quarterly basis, on the last business day each quarter. However, the 2022 Revolving Credit Facility does not require any principal installment payments. As of June 29, 2024, we were in compliance with all covenants required under the 2022 Credit Facilities. See Note 8 to our condensed consolidated financial statements included in Part I, Item 1 of this Form 10-Q for further information.

For each of the three months ended June 29, 2024 and July 1, 2023, we made the required quarterly amortization payments on the 2022 Term Loan of $1.6 million. For each of the six months ended June 29, 2024 and July 1, 2023, we made the required amortization payments on the 2022 Term Loan of $3.1 million. We made no voluntary prepayments on our term loans during each of the three and six months ended June 29, 2024 and July 1, 2023.

In April 2022, management approved and commenced a restructuring plan that will position us for stronger performance. The restructuring plan will mainly reduce headcount and consolidate facilities. As a result of this restructuring plan, we analyzed the need to write-down inventory and impair long-lived assets, including operating lease right-of-use assets. As of June 29, 2024, we estimate the remaining amount of charges related to this initiative will be $3.0 million to $4.0 million in total pre-tax restructuring charges through early 2025 for employee separation and other facility consolidation related expense. The restructuring accrual for severance and benefits of $4.5 million as of June 29, 2024 are expected to be paid out through 2024. On an annualized basis, we anticipate these restructuring actions will result in total cost savings of $11.0 million to $13.0 million. See Note 3 to our condensed consolidated financial statements included in Part I, Item 1 of this Form 10-Q for further information.

In November 2021, we entered into derivative contracts, U.S. dollar-one month LIBOR forward interest rate swaps designated as cash flow hedges, all with an effective date of January 1, 2024, for an aggregate total notional amount of $150.0 million, weighted average fixed rate of 1.8%, and all terminating on January 1, 2031 (“Forward Interest Rate Swaps”). The Forward Interest Rate Swaps mature on a monthly basis, with fixed amount payer payment dates on the first day of each calendar month, commencing on February 1, 2024 through January 1, 2031. See Note 1, Note 4, and Note 8 to our condensed consolidated financial statements included in Part I, Item 1 of this Form 10-Q for further information.

In July 2022, as a result of completing a refinancing of our existing debt, we were required to complete an amendment of the Forward Interest Rate Swaps (“Amended Forward Interest Rate Swaps”). The Forward Interest Rate Swaps were based on U.S. dollar-one month LIBOR and were amended to be based on one month Term SOFR as borrowings using LIBOR are no longer available under the 2022 Credit Facilities. The Amended Forward Interest Rate Swaps weighted average fixed rate is 1.7%, as a result of the difference between U.S. dollar-one month LIBOR and one month Term SOFR. See Note 1, Note 4, and Note 8 to our condensed consolidated financial statements included in Part I, Item 1 of this Form 10-Q for further information.

38

In April 2023, we completed the acquisition of BLR. The initial purchase price for BLR was $115.0 million, net of cash acquired, all payable in cash. We paid a gross aggregate of $117.0 million in cash upon the closing of the transaction. We utilized the 2022 Revolving Credit Facility to complete the acquisition. See Note 2 to our condensed consolidated financial statements included in Part I, Item 1 of this Form 10-Q for further information.

In May 2023, we completed a public offering of our common stock resulting in net proceeds of $85.1 million. The net proceeds of the public stock offering along with cash on hand were used to pay down $85.2 million on the 2022 Revolving Credit Facility that was drawn on and utilized to complete the acquisition of BLR. See Note 2, Note 8, and Note 9 to our condensed consolidated financial statements included in Part I, Item 1 of this Form 10-Q for further information.

We expect to spend a total of $23.0 million to $25.0 million for capital expenditures in 2024 financed by cash generated from operations, principally to support new contract awards in Electronic Systems and Structural Systems. As part of our strategic plan to become a supplier of higher-level assemblies and win new contract awards, additional up-front investment in tooling will be required for newer programs which have higher engineering content and higher levels of complexity in assemblies.

We believe the ongoing aerospace and defense subcontractor consolidation makes acquisitions an increasingly important component of our future growth. We will continue to make prudent acquisitions and capital expenditures for manufacturing equipment and facilities to support long-term contracts for commercial and military aircraft and defense programs.

We monitor our asset base, including the market dynamics of the properties we own, and we may sell such properties and/or enter into sale-leaseback transactions. Such transactions would provide cash for various capital deployment options.

We continue to depend on operating cash flow and the availability of our 2022 Credit Facilities to provide short-term liquidity. Cash generated from operations and bank borrowing capacity is expected to provide sufficient liquidity to meet our obligations during the next twelve months from the date of issuance of these financial statements.

Cash Flow Summary

Net cash provided by operating activities for the six months ended June 29, 2024 was $1.8 million, compared to a net cash used of $9.7 million for the six months ended July 1, 2023. The higher net cash provided by operating activities during the first six months of 2024 was mainly due to higher net income and higher accounts payable, partially offset by higher contract assets.

Net cash used in investing activities was $8.3 million for the six months ended June 29, 2024, compared to $125.3 million in the six months ended July 1, 2023. The lower net cash used in investing activities during the first six months of 2024 compared to the prior year period was mainly due to no acquisitions in the first six months of 2024.

Net cash used in financing activities was $7.0 million for the six months ended June 29, 2024, compared to a net cash provided by financing activities of $111.6 million for the six months ended July 1, 2023. The higher net cash used in financing activities during the first six months of 2024 was mainly due to the issuance of common stock in a public offering in the first six months of 2023 that did not recur in 2024 and lower net borrowings in the first six months of 2024.

Off-Balance Sheet Arrangements

Our off-balance sheet arrangements consist of operating and finance leases not recorded as a result of the practical expedients utilized, right of offset of industrial revenue bonds and associated failed sales-leasebacks on property and equipment, and indemnities, none of which we believe may have a material current or future effect on our financial condition, liquidity, capital resources, or results of operations.

Critical Accounting Policies

The preparation of our condensed consolidated financial statements in accordance with accounting principles generally accepted in the United States requires estimation and judgment that affect the reported amounts of net revenues, expenses, assets and liabilities. For a description of our critical accounting policies, please refer to “Critical Accounting Policies” in Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our 2023 Annual Report on Form 10-K. There have been no material changes in any of our critical accounting policies during the three months ended June 29, 2024.

Recent Accounting Pronouncements

See “Part I, Item 1. Ducommun Incorporated and Subsidiaries—Notes to Condensed Consolidated Financial Statements—Note 1. Summary of Significant Accounting Policies—Recent Accounting Pronouncements” for further information.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Our main market risk exposure relates to changes in U.S. interest rates on our outstanding long-term debt. At June 29, 2024, we had total borrowings of $262.9 million under our 2022 Credit Facilities.

39

The 2022 Term Loan bears interest, at our option, at a rate equal to either (i) Term Secured Overnight Financing Rate (“Term SOFR”) plus an applicable margin ranging from 1.375% to 2.375% per year or (ii) Base Rate (defined as the highest of [a] Federal Funds Rate plus 0.50%, [b] Bank of America’s prime rate, and [c] Term SOFR plus 1.00%, and if the Base Rate is less than zero percent, it will be deemed zero percent) plus an applicable margin ranging from 0.375% to 1.375% per year, in each case based upon the consolidated total net adjusted leverage ratio.

The 2022 Revolving Credit Facility bears interest, at our option, at a rate equal to either (i) Term SOFR plus an applicable margin ranging from 1.375% to 2.375% per year or (ii) Base Rate (defined as the highest of [a] Federal Funds Rate plus 0.50%, [b] Bank of America’s prime rate, and [c] Term SOFR plus 1.00%, and if the Base Rate is less than zero percent, it will be deemed zero percent) plus an applicable margin ranging from 0.375% to 1.375% per year, in each case based upon the consolidated total net adjusted leverage ratio.

A hypothetical 10% increase or decrease in the interest rate would have an immaterial impact on our financial condition and results of operations.

Item 4. Controls and Procedures

Disclosure Controls and Procedures

The Company’s chief executive officer (“CEO”) and chief financial officer (“CFO”) have conducted an evaluation of the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934) as of June 29, 2024. The Company had previously reported a material weakness in internal control over financial reporting related to not designing and maintaining effective controls over the accuracy of contract terms and the reasonableness of gross margin assumptions used to recognize revenue. Specifically, the Company did not verify that amendments to purchase orders and gross margin percentage assumptions used in the Company’s revenue recognition analysis were properly reviewed at a sufficient level of precision, which was described in Item 9A in the Management’s Report on Internal Control Over Financial Reporting in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023. As a result of the material weakness in the Company’s internal control over financial reporting, which was not remediated as of June 29, 2024, the CEO and CFO concluded the Company’s disclosure controls and procedures were not effective as of June 29, 2024.

Remediation of Material Weakness

We have implemented remediation steps to address the material weakness described above to improve our internal control over verification of amendments to purchase orders and the gross margin percentage assumptions used to recognize revenue.

Actions taken:

•We have redesigned our existing controls to expand the selection criteria for contracts requiring an estimate at completion (“EAC”) analysis to support the gross margin percentage used for revenue recognition.

•We have increased the rigor and review of the EAC process, including standardization of the analysis and related documentation and verification of the contract value utilized to the underlying customer purchase order.

•We have implemented additional analytical procedures to ensure the accuracy of gross margin assumptions.

While significant progress has been made to enhance our internal control over financial reporting relating to the material weakness, additional time will be required to assess and ensure the sustainability of these processes and procedures. We expect to complete the assessment and ensure sustainability of these processes and procedures during 2024; however, we cannot make any assurances that such actions will be completed during 2024. Until the remediation steps set forth above are fully implemented and concluded to be operating effectively, the material weakness described above will continue to exist.

Changes in Internal Control over Financial Reporting

Except as otherwise discussed above under “Remediation of Material Weakness,” there were no other changes in our internal control over financial reporting during the three months ended June 29, 2024 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

The Annual Meeting of Stockholders shall be held each year on such day, other than a legal holiday, and at such time and place, or by virtual platform, as may be designated by the Board of Directors and stated in the notice of the meeting or in a duly executed waiver of notice thereof, for the purpose of electing Directors and for the transaction of such other business as may be brought before the meeting. If such annual meeting is not held, or the Directors are not elected thereat, Directors may be elected at a special meeting held for that purpose, and it shall be the duty of the Chairman of the Board of Directors, the Chief Executive Officer, the President, any Executive Vice President, any Senior Vice President, any Vice President or the Secretary, upon the demand of any stockholder entitled to vote, to call such special meeting.

In the absence of a quorum, any meeting of stockholders may be adjourned from time to time by the vote of a majority of the voting stock, the holders of which are either present in person or represented by proxy thereat. The stockholders present at a meeting at which a quorum is present may continue to do business until adjournment, notwithstanding the withdrawal of enough stockholders to leave less than a quorum.

Section 6.    Adjournments. When a meeting is adjourned for thirty (30) days or more, notice of the adjourned meeting shall be given as in the case of the original meeting, but when a meeting is adjourned for less than thirty (30) days it is not necessary to give any notice of the time and place of the adjourned meeting or of the business to be transacted thereat other than by announcement at the meeting at which the adjournment is taken.

The Secretary of the Corporation shall act as Secretary at all meetings of the stockholders, but in the absence of the Secretary at

any meeting of the stockholders, the presiding officer may appoint any person to act as Secretary of the meeting.

Section 8.    Voting.

(a)    Each stockholder shall, at each meeting of the stockholders, be entitled to vote in person or by proxy each share or fractional share of the stock of the Corporation having voting rights on the matter in question and which shall have been held by him and registered in his name on the books of the Corporation:

(i)    on the date fixed pursuant to Article II, Section 11 of these Bylaws as the record date for the determination of stockholders entitled to notice of and to vote at such meeting, or

(ii)    if no such record date shall have been so fixed, then (a) at the close of business on the day next preceding the day on which notice of the meeting shall be given, or (b) if notice of the meeting shall be waived, at the close of business on the day next preceding the day on which the meeting shall be held.

(b)    Shares of its own stock belonging to the Corporation shall not be entitled to vote. Persons holding in a fiduciary capacity stock of the Corporation shall be entitled to vote such stock so held. A person whose stock is pledged shall be entitled to vote such stock, unless in the transfer by the pledger on the books of the Corporation he shall have expressly empowered the pledgee to vote thereon, in which case only the pledgee, or his proxy, may represent such stock and vote thereon. Stock having voting power standing of record in the names of two or more persons, whether fiduciaries, members of a partnership, joint tenants, tenants in common, tenants by the entirety or otherwise, or with respect to which two or more persons have the same fiduciary relationship, shall be voted in accordance with the provisions of the General Corporation Law of the State of Delaware.

(c)    Any such voting rights may be exercised by the stockholder entitled thereto in person or by his proxy appointed by an instrument in writing or by a transmission permitted by law, including Rule 14a-19 promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), subscribed by such stockholder or by his attorney thereunto authorized and delivered to the Secretary of the meeting; provided, however, that no proxy shall be voted or acted upon after three years from its date unless said proxy shall provide for a longer period. The attendance at any meeting of a stockholder who may theretofore have given a proxy shall not have the effect of revoking the same unless he shall in writing so notify the Secretary of the meeting prior to the voting of the proxy. At any meeting of the stockholders all matters other than the election of Directors, except as otherwise provided in the Certificate of Incorporation, these Bylaws or by law, shall be decided by the vote of majority in voting interest of the stockholders present in person or by proxy and entitled to vote thereat and thereon, a quorum being present. The vote at any meeting of the stockholders on any question need not be by ballot, unless so directed by the Chairman of the meeting. On a

vote by ballot each ballot shall be signed by the stockholder voting, or by his proxy, if there be such proxy, and it shall state the number of shares voted. Except as otherwise provided in the Certificate of Incorporation, Directors shall be elected by a plurality of the votes cast by the holders of the shares present in person or represented by proxy at the meeting and entitled to vote for the election of such Directors.

Section 9.    Inspectors of Election. In advance of any meeting of stockholders, the Board of Directors may appoint inspectors of election to act at such meeting or any adjournment thereof. If inspectors of election be not so appointed, the Chairman of any such meeting may make such appointment at the meeting. The number of inspectors shall be either one or three.

Section 10.    Consent of Absentees. The transactions of any meeting of stockholders, either annual or special, however called and noticed, shall be as valid as though had at a meeting duly held after regular call and notice, if a quorum be present either in person or by proxy, and if, either before or after the meeting, each of the stockholders entitled to vote, not present in person or by proxy, signs a written waiver of notice. All such waivers shall be filed with the corporate records or made a part of the minutes of the meeting. Attendance of a person at a meeting of stockholders shall constitute a waiver of notice of such meeting, except when the stockholder attends the meeting for the express purpose of objecting, at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened.

Section 11.    Record Date and Closing Stock Books. The Board of Directors may fix a record date for the determination of the stockholders entitled to notice of and to vote at any meeting of stockholders, or for the determination of the stockholders entitled to receive any dividend or distribution or any allotment of rights, or to exercise rights in respect to any change, conversion or exchange of shares. The record date so fixed shall not be more than sixty (60) nor less than ten (10) days before the date of any such meeting, nor more than sixty (60) days prior to any other action. When a record date is so fixed, only stockholders who are such of record on that date are entitled to notice of and to vote at the meeting or to receive the dividend, distribution, or allotment of rights, or to exercise the rights, as the case may be, notwithstanding any transfer of any shares on the books of the Corporation after the record date. The Board of Directors may close the books of the Corporation against transfers of shares during the whole or any part of a period not more than sixty (60) days prior to the date of a stockholders’ meeting, the date when the right to any dividend, distribution, or allotment of rights vests, or the effective date of any change, conversion or exchange of shares. A determination of stockholders entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of such meeting; provided, however, that the Board of Directors may fix a new record date for the adjourned meeting.

Section 12.    Conduct of Meetings. The Chairman of the Board of Directors shall have complete authority to establish rules of conduct governing all meetings of stockholders. These rules may include, but shall not be limited to, rules related to attendance, questions from the audience and similar matters. Notwithstanding the above, the nomination at any meeting of stockholders of any person to serve as a Director shall not be valid unless (i) the nomination of such person has been approved by resolution of the Board of Directors of the Corporation, or (ii)

notice of the nomination of such person has been delivered to the Secretary of the Corporation in full compliance with the procedures set forth in Article II, Section 13 hereof.

Section 13.    Notice of Stockholder Business and Nominations.

No business (including nominations) shall be conducted at the annual meeting except in accordance with the procedures set forth in this Article II, Section 13.

The Corporation may require any proposed nominee to furnish such other information as it may reasonably require to determine the eligibility of such proposed nominee to serve as a director of the Corporation, including any information that could be material to a reasonable stockholder’s understanding of the independence, or lack thereof, of such nominee.

(c)    A stockholder providing notice of business proposed to be brought before a meeting, including with respect to nominations of directors, shall, in order for such notice to be considered timely, further update and supplement such notice, if necessary, so that the information provided or required to be provided in such notice under this Section 13 shall be true and correct as of the record date for the meeting and as of the date that is ten (10) business days prior to the date of the meeting or any adjournment or postponement thereof, and such update and supplement shall be delivered in writing to the Secretary at the principal executive offices of the Corporation not later than ten (10) days after the record date for the meeting (in the case of the update and supplement required to be made as of the record date), and not later than eight (8) business days prior to the date for the meeting or any adjournment or postponement thereof (in the case of the update and supplement required to be made as of ten (10) business days prior to the meeting or any adjournment or postponement thereof).

stockholder (1) provides notice pursuant to Rule 14a-19(b) promulgated under the Exchange Act and (2) subsequently fails to comply with the requirements of Rule 14a-19(a)(2) and Rule 14a-19(a)(3) promulgated under the Exchange Act, including the provision to the Corporation of notices required thereunder in a timely manner, then the Corporation shall disregard any proxies or votes solicited for such stockholder’s director nominees. Upon request by the Corporation, if any such stockholder provides notice pursuant to Rule 14a-19(b) promulgated under the Exchange Act, such stockholder shall deliver to the Corporation, no later than five (5) business days prior to the applicable meeting, reasonable evidence that it has met the requirements of Rule 14a-19(a)(3) promulgated under the Exchange Act.

    3.    Vesting. The Award shall vest at the end of the 3-year performance period, beginning as ofJanuary 1, 202_ and ending on December 31, 202_(the “Performance Period”). The vesting of the Award shall be subject to the Corporation achieving during the Performance Period the Diluted Earnings Per Share and Relative Total Shareholder Return, as provided in Exhibit A attached hereto. Following the end of each fiscal year of the Performance Period and the collection of relevant data necessary to determine the extent to which the performance goals set forth in Exhibit A have been satisfied, the Committee will determine: (a) the amount of Diluted Earnings Per Share that was achieved by the Corporation for each fiscal year of the Performance Period, and (b) the percentage and number of the Target Units for each fiscal year (for each such fiscal year, the “Earned Units”) that will become Vested Units (as defined in Exhibit A) as of the last day of the Performance Period or earlier as provided in Section 5(b). Following the end of the Performance Period and collection of relevant data necessary to determine the extent to which the performance goals set forth in Exhibit A have been satisfied, the Committee will determine: (a) the Relative Total Shareholder Return that was achieved by the Corporation over the Performance Period, and (b) the multiplier that will be applied to the Earned Units to calculate the total number of Vested Units as of the last day of the Performance Period, as provided in Exhibit A attached hereto. The Committee shall make these determinations in its sole discretion. The level of achievement of Diluted Earnings Per Share and Relative Total Shareholder Return shall be evidenced by the Committee’s written certification. For the avoidance of doubt, any performance stock units subject to this Award that do not vest in accordance with the forgoing shall expire without consideration at the end of the Performance Period.

4.    Settlement of Vested Units. Upon the Committee’s written certification as set forth in Section 3, of the vesting of all or a portion of the Award, one share of Common Stock shall be issuable for each Vested Unit (as defined in Exhibit A) (the “PSU Shares”). Thereafter, the Corporation will transfer such PSU Shares to the Award Holder no later than March 15th of the calendar year after the end of the Performance Period subject to the satisfaction of any required tax withholding obligations, securities law registration or other requirements, and applicable stock exchange listing.

Notwithstanding the foregoing, the Award Holder may elect, on a form and in a manner prescribed by the Corporation, to defer any payment of Vested Units, provided that any such deferral of payment must comply with any applicable requirements of Section 409A of the Code.

2

employment.

As used herein, the term “retirement” shall mean the Award Holder’s termination of employment with the Corporation or a Subsidiary, when either (x) the Award Holder is sixty-five (65) or more years of age, or (y) the Award Holder is sixty (60) or more years of age and has completed at least five (5) years of service with the Corporation or a Subsidiary. As used herein, the term “permanent disability” shall mean the date on which the Award Holder has not worked or been able to work due to physical or mental incapacity for a period of one hundred eighty (180) consecutive days.

    (b)    Upon the termination of the Award Holder’s employment with the Corporation or a Subsidiary as a result of death or permanent disability as provided in Section 5(a), (i) for each full fiscal year that the Award Holder was employed by the Corporation or a Subsidiary, the Earned Units (as defined in Section 3) shall vest immediately (and such Earned Units shall be settled into shares of Common Stock as soon as practicable following the Award Holder’s termination of employment but in no event later than 60 days after such termination), and (ii) for the remaining fiscal years of the Performance Period, the Target Units shall vest at such time as they become Earned Units (based on actual performance and subject to Committee certification in accordance with, Section 3) and such Earned Units shall be settled into shares of Common Stock as soon as practicable following the Committee’s certification of the Earned Units but in no event later than sixty (60) days after such certification. For the avoidance of doubt, the Total Vested Units Modifier (as defined in Exhibit A) shall not be applied in determining the Vested Units for any Award covered by this Section 5(b)(i)-(ii). Upon the termination of the Award Holder’s employment with the Corporation or a Subsidiary as a result of retirement as provided in Section 5(a), (iii) for each full fiscal year that the Award Holder was employed by the Corporation or a Subsidiary, the Earned Units (as defined in Section 3) shall continue to be subject to the vesting provisions of Section 3 based on the actual amount of Diluted Earnings Per Share that was achieved by the Corporation for each such full fiscal year that the Award Holder was employed by the Corporation or a Subsidiary, and (iv) for the remaining fiscal years of the Performance Period, the Target Units shall vest at such time as they become Earned Units (based on actual performance and subject to Committee certification in accordance with Section 3) and such Earned Units shall be settled into shares of Common Stock as soon as practicable following the Committee’s certification of the Earned Units but in no event later than 60 days after such certification. For the avoidance of doubt, the Total Vested Units Modifier (as defined in Exhibit A) shall be applied in determining the Vested Units for any Award covered by this Section 5(b)(iii)-(iv). To the extent any payment hereunder is considered nonqualified deferred compensation subject to Section 409A of the Code, all such payments and settlements shall be made in compliance with Section 409A of the Code and a termination of employment shall not be deemed to have occurred for purposes of any payments contingent thereon unless such termination is also a “separation from service” within the meaning of Section 409A of the Code. In addition, if the Award Holder is deemed at the time of such separation from service to be a specified employee (within the meaning of Section 409A of the Code) and such delayed commencement is otherwise required in order to avoid a prohibited distribution under Section 409A(a)(2) of the Code, any payment or benefit hereunder that is deemed to

3

constitute nonqualified deferred compensation shall be delayed and paid, without interest, on the earlier of (i) the first day of the seventh month following the date of such Award Holder’s separation from service or (ii) the date of the Award Holder’s death.

    8.    Legal Requirements.

Exhibit A

For purposes of this performance stock unit agreement, the “Diluted Earnings Per Share” means the diluted earnings per share of the Corporation for each of the Corporation’s fiscal years ending December 31, 202_, December 31, 202_ and December 31, 202_ as included in the Corporation’s audited financial statements, subject to adjustment as provided herein. The Diluted Earnings Per Share shall be adjusted (as determined by the Committee) (i) for changes in accounting, (ii) for discontinued operations (including businesses and product lines that are sold), (iii) to exclude gain or loss on the sale of any business or product line, including but not limited to post-closing adjustments to the purchase price, any indemnity or similar payments, and any costs or expenses in connection therewith, (iv) to exclude any asset impairment write-offs or charges (whether of goodwill, intangible or tangible assets), (v) to exclude any transaction-related costs or expenses arising in connection with the purchase or sale of any business or product line, including but not limited to the effects of Financial Accounting Standards Board Accounting Standards Codification Topic 805, (vi) to exclude any costs or expenses arising in connection with the refinancing, restructuring or prepayment of any Debt, including but not limited to the unamortized portion of any original issue discount, the unamortized portion of any original issue costs and expenses, and any prepayment or make-whole payments, costs or expenses and (vii) any restructuring, reorganization or other costs, expenses or charges that the Compensation Committee determines should be adjusted to fairly reflect the operating performance of the Company. An appropriate adjustment in the Diluted Earnings Per Share amounts in the table below also shall be made for any of the events described in Section 6(a) above.

For purposes of this performance stock unit agreement, the “Relative Total Shareholder Return” means the percentile ranking over the Performance Period of the Corporation’s total shareholder return as compared to the total shareholder return of the companies in the Russell 2000 Index at the beginning of the Performance Period. The determination of the total shareholder return for the Corporation and the companies in the Russell 2000 Index shall include the appreciation or depreciation of stock prices plus dividends paid as if reinvested, and shall be determined based on the average closing price of the Corporation’s common stock and the average closing price of the companies in the Russell 2000 Index over the first thirty (30) trading days of the Performance Period compared to the last thirty (30) trading days of the Performance Period. If the Russell 2000 Index ceases to be published, the Committee shall, in its discretion, substitute another broad-based stock index that it determines is appropriate.

After the end of the Corporation’s fiscal year ending December 31, 202_, the Committee shall determine the Corporation’s Diluted Earnings Per Share for such fiscal year and the applicable percentage of Target Units earned with respect to such performance measure for such fiscal year. After the end of the Corporation’s fiscal year ending December 31, 202_, the Committee shall determine the Corporation’s Diluted Earnings Per Share for such fiscal year and the applicable percentage of Target Units earned with respect to such performance measure for such fiscal year. After the end of the Corporation’s fiscal year ending December 31, 202_, the Committee shall determine the Corporation’s Diluted Earnings Per Share for such fiscal year and

7

the applicable percentage of Target Units earned with respect to such performance measure for such fiscal year. If the Diluted Earnings Per Share does not equal or exceed the thresholds in the table below, the Award shall expire without consideration.

Diluted Earnings Per Share	202_	202_	202_	Total
Threshold      Vesting % of Target Units	$x.xx 10%	$x.xx 10%	$x.xx 10%	30%
Target      Vesting % of Target Units	$x.xx 33%	$x.xx 33%	$x.xx 34%	100%
Maximum      Vesting % of Target Units	$x.xx 66%	$x.xx 66%	$x.xx 68%	200%

In the event that the Corporation’s Diluted Earnings Per Share for any fiscal year of the Performance Period falls between two of the percentages listed in the table above, the applicable percentage of Target Units earned based on such achievement shall be determined by linear interpolation. The total number of performance stock units subject to the Award that are earned based upon the Corporation’s achievement over the Performance Period (as determined by the Committee) will be equal to the sum of (i) the percentage determined by reference to the table above with respect to the Corporation’s Diluted Earnings Per Share for the fiscal year ending December 31, 202_ multiplied by the number of Target Units set forth in Section 1 above, plus (ii)  the percentage determined by reference to the table above with respect to the Corporation’s Diluted Earnings Per Share for the fiscal year ending December 31, 202_ multiplied by the number of Target Units set forth in Section 1 above, plus (iii) the percentage determined by reference to the table above with respect to the Corporation’s Diluted Earnings Per Share for the fiscal year ending December 31, 202_ multiplied by the number of Target Units set forth in Section 1 above (such units collectively, the “Earned Units”).

After the end of the Performance Period, the Committee shall determine the Corporation’s Relative Total Shareholder Return (compared to the companies in the Russell 2000 Index at the beginning of the Performance Period) over the Performance Period. The Committee, in its discretion, shall establish such procedures as it deems appropriate to determine the Corporation’s percentile rank in Relative Total Shareholder Return. The total “Vested Units” will then be determined by multiplying the Earned Units by the Total Vested Units Modifier in the table below.

8

Notwithstanding the foregoing, the Total Vested Units Modifier shall not be greater than 1.0 unless the Corporation’s total shareholder return over the Performance Period is greater than zero.

Relative Total Shareholder Return v. Russell 2000 Index
Total Shareholder Return Percentile Rank	Total Vested Units Modifier
81% - 100%	1.25
71% - 80%	1.15
61% - 70%	1.10
41% - 60%	1.00
31% - 40%	.90
21% - 30%	.85
0% - 20%	.75

Notwithstanding anything herein to the contrary, in no event will more than two hundred fifty percent (250%) of the number of Target Units become vested hereunder. Performance stock units granted under this Award that are not vested and remain subject to forfeiture are referred to herein as “Unvested Units.”

1

Following the end of each fiscal year of the Performance Period and the collection of relevant data necessary to determine the extent to which the performance goals set forth in Exhibit A have been satisfied, the Committee will determine: (a) the amount of Diluted Earnings Per Share that was achieved by the Corporation for each fiscal year of the Performance Period, and (b) the percentage of the Target Award for each fiscal year (for each such fiscal year, the “Earned Award”) that will become the Vested Award (as defined in Exhibit A) as of the last day of the Performance Period or earlier as provided in Section 5(b).

The Committee shall make these determinations in its sole discretion. The level of achievement of Diluted Earnings Per Share and Relative Total Shareholder Return shall be evidenced by the Committee’s written certification.

4.    Settlement of Vested Award.

5.    Termination.

    (a)    If the Award Holder’s employment with the Corporation or a Subsidiary terminates before the end of the Performance Period for any reason, except as provided in this Section 5, then the Award will be forfeited and cancelled and surrendered to the Corporation without payment of any consideration, effective on the date of the Award Holder’s termination of employment. Upon the termination of the Award Holder’s employment with the Corporation or a Subsidiary as a result of (i) death or “permanent disability” (as defined herein) or (ii) “retirement” (as defined herein), the amount of the Vested Award and the vesting of such Vested Award shall be determined in accordance with Section 5(b) below.

For the avoidance of doubt, the Total Vested Award Modifier (as described in Exhibit A) shall not be applied in determining the Vested Award for any Award covered by this Section 5(b).

For the avoidance of doubt, the Total Vested Units Modifier (as defined in Exhibit A) shall be applied in determining the Vested Units for any Award covered by this Section 5(b)(iii)-(iv). To the extent any payment hereunder is considered nonqualified deferred compensation subject to Section 409A of the Code, all such payments and settlements shall be made in compliance with Section 409A of the Code and a termination of employment shall not be deemed to have occurred for purposes of any payments contingent thereon unless such termination is also a “separation from service” within the meaning of Section 409A of the Code. In addition, if the Award Holder is deemed at the time of such separation from service to be a specified employee (within the meaning of Section 409A of the Code) and such delayed commencement is otherwise required in order to avoid a prohibited distribution under Section 409A(a)(2) of the Code, any payment or benefit hereunder that is deemed to constitute nonqualified deferred compensation shall be delayed and paid, without interest, on the earlier of (i) the first day of the seventh month following the date of such Award Holder’s separation from service or (ii) the date of the Award Holder’s death.

6.         Reserved.

    12.    Other Programs.

CASH-BASED LONG-TIME INCENTIVE AWARD AGREEMENT

Exhibit A

For purposes of this Agreement, the “Diluted Earnings Per Share” means the diluted earnings per share of the Corporation for each of the Corporation’s fiscal years ending December 31, 202_, December 31, 202_ and December 31, 202_ as included in the Corporation’s audited financial statements, subject to adjustment as provided herein. The Diluted Earnings Per Share shall be adjusted (as determined by the Committee) (i) for changes in accounting, (ii) for discontinued operations (including businesses and product lines that are sold), (iii) to exclude gain or loss on the sale of any business or product line, including but not limited to post-closing adjustments to the purchase price, any indemnity or similar payments, and any costs or expenses in connection therewith, (iv) to exclude any asset impairment write-offs or charges (whether of goodwill, intangible or tangible assets), (v) to exclude any transaction-related costs or expenses arising in connection with the purchase or sale of any business or product line, including but not limited to the effects of Financial Accounting Standards Board Accounting Standards Codification Topic 805, (vi) to exclude any costs or expenses arising in connection with the refinancing, restructuring or prepayment of any Debt, including but not limited to the unamortized portion of any original issue discount, the unamortized portion of any original issue costs and expenses, and any prepayment or make-whole payments, costs or expenses and (vii) any restructuring, reorganization or other costs, expenses or charges that the Compensation Committee determines should be adjusted to fairly reflect the operating performance of the Company. An appropriate adjustment in the Diluted Earnings Per Share amounts in the table below also shall be made for any change in capitalization as described in the Plan.

For purposes of this Agreement, the “Relative Total Shareholder Return” means the percentile ranking over the Performance Period of the Corporation’s total shareholder return as compared to the total shareholder return of the companies in the Russell 2000 Index at the beginning of the Performance Period. The determination of the total shareholder return for the Corporation and the companies in the Russell 2000 Index shall include the appreciation or depreciation of stock prices plus dividends paid as if reinvested, and shall be determined based on the average closing price of the Corporation’s common stock and the average closing price of the companies in the Russell 2000 Index over the first thirty (30) trading days of the Performance Period compared to the last thirty (30) trading days of the Performance Period. If the Russell 2000 Index ceases to be published, the Committee shall, in its discretion, substitute another broad-based stock index that it determines is appropriate.

After the end of the Corporation’s fiscal year ending December 31, 202_, the Committee shall determine the Corporation’s Diluted Earnings Per Share for such fiscal year and the applicable percentage of Target Award earned with respect to such performance measure for such fiscal year. After the end of the Corporation’s fiscal year ending December 31, 202_, the Committee shall determine the Corporation’s Diluted Earnings Per Share for such fiscal year and the applicable percentage of Target Award earned with respect to such performance measure for such fiscal year. After the end of the Corporation’s fiscal year ending December 31, 202_, the

6

Committee shall determine the Corporation’s Diluted Earnings Per Share for such fiscal year and the applicable percentage of Target Award earned with respect to such performance measure for such fiscal year. If the Diluted Earnings Per Share does not equal or exceed the thresholds in the table below, the Award shall expire without consideration.

Diluted Earnings Per Share	202_	202_	202^	Total
Threshold      Vesting % of Target Award	$x.xx 10%	$x.xx 10%	$x.xx 10%	30%
Target      Vesting % of Target Award	$x.xx 33%	$x.xx 33%	$x.xx 34%	100%
Maximum      Vesting % of Target Award	$x.xx 66%	$x.xx 66%	$x.xx 68%	200%

In the event that the Corporation’s Diluted Earnings Per Share for any fiscal year of the Performance Period falls between two of the percentages listed in the table above, the applicable percentage of Target Award earned based on such achievement shall be determined by linear interpolation. The total value of the Award earned based upon the Corporation’s achievement over the Performance Period (as determined by the Committee) will be equal to the sum of (i) the percentage determined by reference to the table above with respect to the Corporation’s Diluted Earnings Per Share for the fiscal year ending December 31, 202_ multiplied by the amount of the Target Award set forth in Section 1 above, plus (ii)  the percentage determined by reference to the table above with respect to the Corporation’s Diluted Earnings Per Share for the fiscal year ending December 31, 202_ multiplied by the amount of the Target Award set forth in Section 1 above, plus (iii) the percentage determined by reference to the table above with respect to the Corporation’s Diluted Earnings Per Share for the fiscal year ending December 31, 202_ multiplied by the amount of the Target Award set forth in Section 1 above (collectively, the “Earned Award”).

After the end of the Performance Period, the Committee shall determine the Corporation’s Relative Total Shareholder Return (compared to the companies in the Russell 2000 Index at the beginning of the Performance Period) over the Performance Period. The Committee, in its discretion, shall establish such procedures as it deems appropriate to determine the Corporation’s percentile rank in Relative Total Shareholder Return. The total Vested Award will then be determined by multiplying the Earned Award by the Total Vested Award Modifier in the table below. Notwithstanding the foregoing, the Total Vested Award Modifier shall not be greater

7

than 1.0 unless the Corporation’s total shareholder return over the Performance Period is greater than zero.

The Corporation or any Subsidiary of the Corporation may make such provisions as it may deem appropriate for the withholding of any taxes which the Corporation or such Subsidiary determines it is required to withhold in connection with this stock option agreement and the transactions contemplated hereby, and the Corporation or any such Subsidiary may require the Option Holder or other person exercising this Option to pay to the Corporation or such Subsidiary in cash any amount or amounts which may be required to be paid as withheld taxes in connection with any exercise of this Option or any other transaction contemplated hereby as a condition to the exercise of this Option and issuance of shares of the Common Stock, provided, however, that any amount withheld for taxes in connection with any exercise of this Option may, at the election of the Option Holder, be paid with previously issued shares of Common Stock or the deduction of shares of Common Stock to be issued in connection with the exercise of this Option.

    12.    No Assignments. Neither this stock option agreement, nor this option nor any other rights and privileges granted hereby shall be transferred, assigned, pledged or hypothecated in any way, whether by operation of law of descent and distribution. Upon any attempt to so transfer, assign, pledge, hypothecate or otherwise dispose of this stock option agreement, this option or any other right or privilege granted hereby contrary to the provisions hereof, this stock option agreement, this option and all of such rights and privileges shall immediately become null and void provided however, that the Award Holder may transfer an Award to any “family member” (as such term is defined in Section A.1(a)(5) of the General Instructions to Form S-8 under the Securities Act of 1933, as amended (“Form S-8”)), to trusts solely for the benefit of such family members and to partnerships in which such family members and/or trusts are the only partners; provided that the transfer is pursuant to a gift or a domestic relations order to the extent permitted under the General Instructions to Form S-8, and provided further, that such

transferee acknowledges and agrees that the Award remains subject to all of the terms and conditions of this Agreement and the Plan.

    13.    Other Programs. Nothing contained in this stock option agreement shall affect the right of the Option Holder to participate in and receive benefits under and in accordance with the then current provisions of any pension, insurance, profit-sharing or other employee benefit plan or program of the Corporation or of any Subsidiary of the Corporation.

    14.    Non-Solicitation of Customers; Non-Competition. By signing this stock option agreement, the Option Holder agrees that while employed by the Corporation and for a period of one year following the Option Holder’s departure from the Corporation, the Option Holder will not (directly or in association with others) call on or solicit any of the Corporation’s customers with whom the Option Holder had personal contact while employed by the Corporation, for the purpose of providing the customers with goods and/or services similar in nature to those provided by the Corporation in its Business (as defined below). The Option Holder further agrees that for the same time period, the Option Holder will not, directly or indirectly, engage in any activity which is the same as or competitive with the Business including, without limitation, engagement as an officer, director, proprietor, employee, partner, investor (other than as a holder of less than 2% of the outstanding capital stock of a publicly traded corporation), guarantor, consultant, advisor, agent, sales representative or other participant, in any market which the Corporation conducts its Business. For purposes of this stock option agreement, the term “Business” means engineering and manufacturing services for high-performance products and high-cost-of failure applications used primarily in the aerospace and defense, industrial, medical and other industries, and any other activity of the Corporation or any of its affiliates. This Section 14 is not intended to prevent the Option Holder from engaging in any activity that is not the same as or competitive with the Business. The Option Holder acknowledges that the Corporation would not have awarded the option granted under this stock option agreement absent the Option Holder’s agreement to be bound by the promises made in this Section 14.

15.Acknowledgment; Injunctive Relief. By signing this stock option agreement, the Option Holder acknowledges having carefully read and considered all the terms and conditions of this stock option agreement, including the restraints imposed pursuant to Section 14. The Option Holder also agrees that each of the restraints contained herein is necessary for the protection of the goodwill, confidential information, trade secrets and other legitimate interests of the Corporation; that each and every one of these restraints is reasonable in respect to subject matter, length of time and geographic area; and that these restraints, individually or in the aggregate, will not prevent the Option Holder from obtaining other suitable employment during the period of such restraints. The Option Holder further acknowledges that breach any of the covenants contained in Section 14 would result in irreparable damage to the Corporation. The Option Holder therefore agrees that the Corporation, in addition to any other remedies available to it, shall be entitled to injunctive relief against the breach or threatened breach of said covenants. The Option Holder and the Corporation further agree that, in the event that any provision of Section 14 shall be determined by any court of competent jurisdiction to be unenforceable by reason of its being extended over too great a time, too large a geographic area

or too great a range of activities, such provision shall be deemed to be modified to permit its enforcement to the maximum extent permitted by law.

    16.    Violation of Promises. By signing this stock option agreement, the Option Holder agrees that if the Option Holder violates any of the promises in Section 14, the Option Holder’s right to the shares of Common Stock upon exercise of the option shall not have been earned and the unexercised portion of the option, whether vested or not, will be immediately cancelled.

    17.    The Plan. The option hereby granted is subject to, and the Corporation and Option Holder agree to be bound by all of the terms and conditions of the Plan as the same may be amended from time to time in accordance with the terms thereof, but no such amendment may adversely affect the Option Holder’s rights under this stock option agreement. Option Holder acknowledges receipt of a complete copy of the Plan.

    18.    Consideration. The consideration for the rights and benefits conferred on Option Holder by this option are the services rendered by the Option Holder after and not before the grant of this option.

    19.    Applicable Law. The interpretation, performance and enforcement of this Agreement shall be governed by the laws of the state in which the Option Holder is employed by the Corporation. Sections 14, 15 and 16 shall not apply to Option Holders employed by the Corporation in California.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Description of Business

We are a leading global provider of innovative, value-added proprietary products and manufacturing solutions for high-performance products and high-cost-of failure applications used primarily in the aerospace and defense (“A&D”), industrial, medical and other industries (collectively, “Industrial”). Our operations are organized into two primary businesses: the Electronic Systems segment (“Electronic Systems”) and the Structural Systems segment (“Structural Systems”), each of which is a reportable operating segment. Electronic Systems designs, engineers and manufactures high-reliability electronic and electromechanical products used in worldwide technology-driven markets including A&D and Industrial end-use markets. Electronic Systems’ product offerings primarily range from prototype development to complex assemblies. Structural Systems designs, engineers and manufactures large, complex contoured aerostructure components and assemblies and supplies composite and metal bonded structures and assemblies. Structural Systems’ products are primarily used on commercial aircraft, military fixed-wing aircraft, and military and commercial rotary-wing aircraft. Both reportable operating segments follow the same accounting principles.

Basis of Presentation

The unaudited condensed consolidated financial statements include the accounts of Ducommun Incorporated and its subsidiaries (“Ducommun,” the “Company,” “we,” “us” or “our”), after eliminating intercompany balances and transactions. The December 31, 2023 condensed consolidated balance sheet data was derived from audited financial statements, but does not contain all disclosures required by accounting principles generally accepted in the United States of America (“GAAP”).

Our significant accounting policies were described in Part IV, Item 15(a)(1), “Note 1. Summary of Significant Accounting Policies” in our Annual Report on Form 10-K for the year ended December 31, 2023 (“2023 Form 10-K”). The financial information included in this Quarterly Report on Form 10-Q (“Form 10-Q”) should be read in conjunction with the 2023 Form 10-K.

In the opinion of management, all adjustments, including recurring accruals, have been made that are necessary to fairly state our condensed consolidated financial position, statements of income, comprehensive income, changes in shareholders’ equity, and cash flows in accordance with GAAP for the periods covered by this Form 10-Q. The results of operations for the three and six months ended June 29, 2024 are not necessarily indicative of the results to be expected for the full year ending December 31, 2024.

Our fiscal quarters typically end on the Saturday closest to the end of March, June and September for the first three fiscal quarters of each year, and on December 31 for our fourth fiscal quarter. As a result of using fiscal quarters for the first three quarters combined with leap years, our first and fourth fiscal quarters can range between 12 1/2 weeks to 13 1/2 weeks while the second and third fiscal quarters remain at a constant 13 weeks per fiscal quarter.

Certain reclassifications have been made to prior period amounts to conform to the current year’s presentation.

Use of Estimates

Certain amounts and disclosures included in the unaudited condensed consolidated financial statements require management to make estimates and judgments that affect the amounts of assets, liabilities (including contract liabilities), revenues and expenses, and related disclosures of contingent assets and liabilities. These estimates are based on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates.

Unsolicited Non-Binding Indication of Interest

On April 8, 2024, our Board of Directors (“BOD”) confirmed receipt of the first unsolicited non-binding indication of interest dated April 1, 2024 (“First IOI”) from Albion River LLC (“Albion”), a private direct investment firm. Albion expressed interest in acquiring all the outstanding shares of Ducommun for $60.00 per share in cash. On April 16, 2024, we issued a press release responding to the First IOI that the BOD had unanimously determined it was not in the best interests of Ducommun and Ducommun shareholders to pursue further discussions regarding the proposal.

Subsequent to our quarter ended June 29, 2024, on July 15, 2024, our BOD received an unsolicited revised non-binding indication of interest from Albion (“Second IOI”), to acquire all outstanding shares of Ducommun for $65.00 per share in cash.

On July 25, 2024, we issued a press release responding to the Second IOI that the BOD had unanimously determined it was not in the best interests of Ducommun and Ducommun shareholders to pursue further discussions regarding the revised proposal.

Earnings Per Share

Basic earnings per share are computed by dividing income available to common shareholders by the weighted-average number of common shares outstanding in each period. Diluted earnings per share is computed by dividing income available to common shareholders by the weighted-average number of common shares outstanding, plus any potentially dilutive shares that could be issued if exercised or converted into common stock in each period.

The net income and weighted-average common shares outstanding used to compute earnings per share were as follows:

Fair Value

Assets and liabilities that are measured, recorded or disclosed at fair value on a recurring basis are categorized using the fair value hierarchy. The fair value hierarchy has three levels based on the reliability of the inputs used to determine the fair value. Level 1, the highest level, refers to the values determined based on quoted prices in active markets for identical assets. Level 2 refers to fair values estimated using significant observable inputs. Level 3, the lowest level, includes fair values estimated using significant unobservable inputs.

We have money market funds which are included as cash and cash equivalents. We also have forward interest rate swap agreements and the fair value of the forward interest rate swap agreements was determined using pricing models that use observable market inputs as of the balance sheet date, a Level 2 measurement.

There were no transfers between Level 1, Level 2, or Level 3 financial instruments in the three months ended June 29, 2024.

Cash and Cash Equivalents

Cash equivalents consist of highly liquid instruments purchased with original maturities of three months or less. These assets are valued at cost, which approximates fair value, and we classify as Level 1. See Fair Value above.

Derivative Instruments

We recognize derivative instruments on our condensed consolidated balance sheets at their fair value. On the date that we enter into a derivative contract, we designate the derivative instrument as a fair value hedge, a cash flow hedge, or a derivative instrument that will not be accounted for using hedge accounting methods. In November 2021, we entered into forward interest rate swap agreements with an aggregate notional amount of $150.0 million, all with an effective date of January 1, 2024 (“Forward Interest Rate Swaps”), to manage our exposure to interest rate movements on a portion of our debt. At the time we entered into the Forward Interest Rate Swaps, there was a high probability of forecasted interest payments on our debts occurring and the swaps were highly effective in offsetting those interest payments; therefore, we elected to apply cash flow hedge accounting. In July 2022, as a result of refinancing all our existing debt, which allowed borrowing based on a Secured Overnight Financing Rate (“SOFR”), we were required to complete an amendment of the Forward Interest Rate Swaps from One Month London Interbank Offered Rate (“LIBOR”) to One Month Term SOFR (“Amended Forward Interest Rate Swaps”), which occurred on the same day. After the transition of the Forward Interest Rate Swaps and debt to SOFR was completed, we determined the hedging relationships were still highly effective as of the amendment date. See Note 4 and Note 8. As of June 29, 2024, all of our derivative instruments were designated as cash flow hedges.

We record changes in the fair value of a derivative instrument that is highly effective and that is designated and qualifies as a cash flow hedge in other comprehensive income (loss), net of tax until our earnings are affected by the variability of cash flows of the underlying hedged item. We report changes in the fair values of derivative instruments that are not designated or do not qualify for hedge accounting in current period earnings. We classify cash flows from derivative instruments in the condensed consolidated statements of cash flows in the same category as the item being hedged or on a basis consistent with the nature of the instrument. Prior to the Amended Forward Interest Rate Swaps being effective on January 1, 2024, we only recorded the changes in fair value of the derivative instruments that were highly effective and that were designated and qualified as cash flow hedges prior to the effective date. See Note 4.

When we determine that a derivative instrument is not highly effective as a hedge, we discontinue hedge accounting prospectively. In all situations in which we discontinue hedge accounting and the derivative instrument remains outstanding, we will carry the derivative instrument at its fair value on our condensed consolidated balance sheets and recognize subsequent changes in its fair value in our current period earnings.

Inventories

Inventories are stated at the lower of cost or net realizable value with cost being determined using a moving average cost basis for raw materials and actual cost for work-in-process and finished goods. The majority of our inventory is charged to cost of sales as raw materials are placed into production. Inventoried costs include raw materials, outside processing, direct labor and allocated overhead, adjusted for any abnormal amounts of idle performance center expense, freight, handling costs, and wasted materials (spoilage) incurred. We assess the inventory carrying value and reduce it, if necessary, to its net realizable value based on customer orders on hand, and internal demand forecasts using management’s best estimates given information currently available. The majority of our revenues are recognized over time, however, for revenue contracts where revenue is recognized using the point in time method, inventory is not reduced until it is shipped or transfer of control to the customer has occurred. Our ending inventory consists of raw materials, work-in-process, and finished goods.

Accumulated Other Comprehensive Income

Accumulated other comprehensive income, as reflected on the condensed consolidated balance sheets under the equity section, was comprised of cumulative pension and retirement liability adjustments, net of tax, and change in net unrealized gains and losses on cash flow hedges, net of tax.

Revenue Recognition

Our customers typically engage us to manufacture products based on designs and specifications provided by the end-use customer. This requires the building of tooling and manufacturing first article inspection products (prototypes) before volume manufacturing. Contracts with our customers generally include a termination for convenience clause.

We have a significant number of contracts that are started and completed within the same year, as well as contracts derived from long-term agreements and programs that can span several years. We recognize revenue under ASC 606, “Revenue from Contracts with Customers” (“ASC 606”), which utilizes a five-step model.

The definition of a contract for us is typically defined as a customer purchase order as this is when we achieve an enforceable right to payment. The majority of our contracts are firm fixed-price contracts. The deliverables within a customer purchase order are analyzed to determine the number of performance obligations. In addition, at times, in order to achieve economies of scale and based on our customer’s forecasted demand, we may build in advance of receiving a purchase order from our customer. When that occurs, we would not recognize revenue until we have received the customer purchase order.

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account under ASC 606. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, control is transferred and the performance obligation is satisfied. The majority of our contracts have a single performance obligation as the promise to transfer the individual goods or services are highly interrelated or met the series guidance. For contracts with multiple performance obligations, we allocate the contract transaction price to each performance obligation using our best estimate of the standalone selling price of each distinct good or service in the contract. The primary method used to estimate the standalone selling price is the expected cost plus a margin approach, under which we forecast our expected costs of satisfying a performance obligation and then add an appropriate margin for that distinct good or service.

We manufacture most products to customer specifications, and the product cannot be easily modified for another customer. As such, these products are deemed to have no alternative use once the manufacturing process begins. In the event the customer invokes a termination for convenience clause, we would be entitled to costs incurred to date plus a reasonable profit. Contract costs typically include labor, materials, overhead, and when applicable, subcontractor costs. For most of our products, we are building assets with no alternative use and have enforceable right to payment, and thus, we recognize revenue using the over time method.

The majority of our performance obligations are satisfied over time as work progresses. Typically, revenue is recognized over time using an input measure (i.e., costs incurred to date relative to total estimated costs at completion, also known as cost-to-cost plus reasonable profit) to measure progress. Our typical revenue contract is a firm fixed price contract, and the cost of raw materials could make up a significant amount of the total costs incurred. As such, we believe using the total costs incurred input method would be the most appropriate method. While the cost of raw materials could make up a significant amount of the total costs incurred, there is a direct relationship between our inputs and the transfer of control of goods or services to the customer.

Contract estimates, known as estimates at completion, are based on various assumptions to project the outcome of future events that can span multiple months or years. These assumptions include among others, labor productivity and availability; the complexity of the work to be performed; the cost and availability of materials; overhead cost rates; and the performance of subcontractors. As a significant change in one or more of these estimates could affect the progress completed (and related profitability) on our contracts, we review and update our contract-related estimates on a regular basis. We recognize such adjustments under the cumulative catch-up method. Under this method, the impact of the adjustment is recognized in the period the adjustment is identified. In any given reporting period, we have a large number of active contracts, which we have defined as a customer purchase order, and changes in estimates may occur on a significant number of these contracts. Given the significant number of contracts that we may have at any given point in time, the varied nature of products produced under such contracts, and the different assumptions, facts and circumstances associated with each individual contract, and the fact that such changes at the contract level are typically not material, we disclose cumulative catch-up adjustments on a net basis.

Net cumulative favorable and unfavorable catch-up adjustments to contracts had the following impact on our operating results:

	(Dollars in thousands)				(Dollars in thousands)
	Three Months Ended				Six Months Ended
	June 29, 2024		July 1, 2023		June 29, 2024		July 1, 2023
Total net revenues	$	387	$	(4,184)	$	(1,548)	$	(7,440)
Operating income	$	387	$	(4,184)	$	(1,548)	$	(7,440)

Payments under long-term contracts may be received before or after revenue is recognized. When revenue is recognized before we bill our customer, a contract asset is created for the work performed but not yet billed. Similarly, when we receive payment before we ship our products to our customer and have met the shipping terms, a contract liability is created for the advance or progress payment. When a contract liability and a contract asset exist on the same contract, we report it on a net basis.

We record provisions for the total anticipated losses on contracts, considering total estimated costs to complete the contract compared to total anticipated revenues, in the period in which such losses are identified. The provisions for estimated losses on contracts require us to make certain estimates and assumptions, including those with respect to the future revenue under a contract and the future cost to complete the contract. Our estimate of the future cost to complete a contract may include assumptions as to changes in manufacturing efficiency, operating and material costs, and our ability to resolve claims and assertions with our customers. If any of these or other assumptions and estimates do not materialize in the future, we may be

required to adjust the provisions for estimated losses on contracts. The provision for estimated losses on contracts is included as part of contract liabilities on the condensed consolidated balance sheets. As of June 29, 2024 and December 31, 2023, provision for estimated losses on contracts were $5.2 million and $5.4 million, respectively. It is reasonably possible we may incur additional losses in the future.

Production cost of contracts includes non-recurring production costs, such as design and engineering costs, and tooling and other special-purpose machinery necessary to build parts as specified in a contract. Production costs of contracts are recorded to cost of sales using the over time revenue recognition model. We review the value of the production cost of contracts on a quarterly basis to ensure when added to the estimated cost to complete, the value is not greater than the estimated realizable value of the related contracts. As of June 29, 2024 and December 31, 2023, production cost of contracts were $6.2 million and $7.8 million, respectively.

Contract Assets and Contract Liabilities

Contract assets consist of our right to payment for work performed but not yet billed. Contract assets are transferred to accounts receivable when we bill our customers. We bill our customers when we ship the products and meet the shipping terms within the revenue contract. Contract liabilities consist of advance or progress payments received from our customers prior to the time transfer of control occurs plus the estimated losses on contracts. When a contract liability and a contract asset exist on the same contract, we report it on a net basis.

Contract assets and contract liabilities from revenue contracts with customers are as follows:

	(Dollars in thousands)
	June 29, 2024		December 31, 2023
Contract assets	$	210,314	$	177,686
Contract liabilities	$	50,034	$	53,492

The increase in our contract assets as of June 29, 2024 compared to December 31, 2023 was primarily due to a net increase of products in work in process in the current period.

The decrease in our contract liabilities as of June 29, 2024 compared to December 31, 2023 was primarily due to a net decrease of advance or progress payments received from our customers in the current period. We recognized $21.0 million of the contract liabilities as of December 31, 2023 as revenues during the six months ended June 29, 2024.

Performance obligations are defined as customer placed purchase orders (“POs”) with firm fixed price and firm delivery dates. Our remaining performance obligations as of June 29, 2024 totaled $840.0 million. Of the remaining performance obligations as of June 29, 2024, we anticipate recognizing an estimated 65% of our remaining performance obligations as revenue during the next 12 months with the remaining performance obligations being recognized in the remainder of 2025 and beyond.

Recent Accounting Pronouncements

Recently Issued Accounting Standards

In March 2024, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2024-02, “Codification Improvements - Amendments to Remove References to the Concepts Statements” (“ASU 2024-02”), which removed references to various FASB Concepts Statements and updates technical corrections such as conforming amendments, clarification to guidance, simplifications to wording or the structure of guidance, and other minor improvements. The new guidance is effective for fiscal years beginning after December 15, 2024, which is our annual period beginning January 1, 2025. Early adoption is permitted. We are evaluating the impact of this standard.

In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“ASU 2023-09”), which provides more transparency about tax information primarily related to the rate reconciliation and the income taxes paid. The new guidance is effective for fiscal years beginning after December 15, 2024, which will be our annual period beginning January 1, 2025. Early adoption is permitted. We are evaluating the impact of this standard.

In November 2023, the FASB issued ASU 2023-07, “Segment Reporting (Topic 280), Improvements to Reportable Segment Disclosures” (“ASU 2023-07”), which expands reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The new guidance is effective for fiscal years beginning after December 15, 2023, which is our annual period beginning January 1, 2024, and interim periods within fiscal years beginning after December 15, 2024, which will be our interim period beginning January 1, 2025. Early adoption is permitted. We are evaluating the impact of this standard.

In October 2023, the FASB issued ASU 2023-06, “Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative” (“ASU 2023-06”), which incorporates updates to the Accounting Standards Codification to align certain SEC disclosure requirements. The amendments impact a variety of topics but are relatively narrow in nature. For entities required to comply with the SEC’s existing disclosure requirements, the effective date for each amendment will be the effective date of the removal of the disclosure requirement from SEC Regulation S-X or SEC Regulation S-K, with early adoption prohibited. The amendments should be applied prospectively. We are evaluating the impact of this standard.

BLR Aerospace, L.L.C. Acquisition

In April 2023, we acquired 100.0% of the outstanding equity interests of BLR Aerospace, L.L.C. (“BLR”), a privately-held leading provider of aerodynamic systems that enhance the productivity, performance, and safety of rotary and fixed-wing aircraft on commercial and military platforms. BLR is located in Everett, Washington. The acquisition of BLR added to our strategy to diversify and offer more customized, value-driven engineered products with aftermarket opportunities.

The initial purchase price for BLR was $115.0 million, net of cash acquired, all payable in cash, subject to adjustments for working capital. We paid a gross aggregate of $117.0 million in cash upon the closing of the transaction. Subsequent to the closing of the transaction, during the three months ended September 30, 2023, the working capital was finalized, resulting in an immaterial adjustment for a final purchase price of $114.4 million, net of cash acquired. We allocated the gross purchase price of $117.0 million to the assets acquired and liabilities assumed at their estimated fair values. The excess of the purchase price over the aggregate fair values of the net assets was recorded as goodwill.

The following table summarizes the estimated fair value of the assets acquired and liabilities assumed at the date of acquisition (in thousands):

	Estimated Fair Value
Cash	$	2,656
Accounts receivable	4,149
Inventories	12,011
Other current assets	891
Property and equipment	2,632
Operating lease right-of-use assets	874
Intangible assets	55,500
Goodwill	41,193
Total assets acquired	119,906
Current liabilities	(2,145)
Other non-current liabilities	(727)
Total liabilities assumed	(2,872)
Total purchase price allocation	$	117,034

	Useful Life (In years)	Estimated Fair Value (In thousands)
Intangible assets:
Technology	23	$	35,600
Customer relationships	10-22	15,000
Trade name	18	4,900
		$	55,500

The intangible assets acquired of $55.5 million were determined based on the estimated fair values using valuation techniques consistent with the income approach to measure fair value, which represented Level 3 fair value measurements. The useful lives were estimated based on the underlying agreements or the future economic benefit expected to be received from the assets. The values for technology and trade name were assessed using the relief from royalty methodology, while the value for customer relationships was estimated based on a multi-period excess earnings approach. Inputs to the income approach models and other aspects of the allocation of the purchase price require judgment. The more significant inputs used in the technology intangible asset valuation included (i) future revenues, (ii) the technology decay rate, (iii) the royalty rate, and (iv) the discount rate. The more significant inputs used in the customer relationships intangible asset valuation included (i) future revenues, (ii) the projected earnings before interest, taxes, and amortization (“EBITA”) margins, (iii) the customer attrition rates, and (iv) the discount rate.

The goodwill of $41.2 million arising from the acquisition is attributable to the benefits we expect to derive from expected synergies from the transaction, including complementary products that will enhance our overall product portfolio, opportunities within new markets, and an acquired assembled workforce. All the goodwill was assigned to the Structural Systems segment.

The BLR acquisition, for tax purposes, is deemed an asset acquisition and thus, the goodwill recognized is deductible for income tax purposes.

Acquisition related transaction costs were not included as components of consideration transferred but have been expensed as incurred. Total acquisition-related transaction costs incurred by us were zero and $0.5 million during the three months ended June 29, 2024 and July 1, 2023, respectively, and zero and $1.3 million during the six months ended June 29, 2024 and July 1, 2023, respectively, and charged to selling, general and administrative expenses.

BLR’s results of operations have been included in our condensed consolidated statements of income since the date of acquisition as part of the Structural Systems segment, and its revenues were less than three percent of total company revenues since the date of acquisition. Pro forma results of operations of the BLR acquisition have not been presented as the effect of the BLR acquisition was not material to our financial results.

Summary of 2022 Restructuring Plan

In April 2022, management approved and commenced a restructuring plan that will better position us for stronger performance. The restructuring plan will mainly reduce headcount and consolidate facilities. As a result of this restructuring plan, we analyzed the need to write-down inventory and impair long-lived assets, including operating lease right-of-use assets. During the three and six months ended June 29, 2024, we recorded total charges of $2.1 million ($0.9 million of which was recorded as cost of sales) and $3.5 million ($0.9 million of which was recorded as cost of sales), respectively. Cumulative through the six months ended June 29, 2024, we recorded aggregate total charges of $25.0 million ($1.7 million of which was recorded as cost of sales). As of June 29, 2024, we estimate the remaining amount of charges related to this initiative will be $3.0 million to $4.0 million in total pre-tax restructuring charges through early 2025 for employee separation and other facility consolidation related expenses.

In the Electronics Systems segment, we recorded no restructuring charges during the three months ended June 29, 2024. We recorded charges of $0.3 million and $0.2 million during the six months ended June 29, 2024, for severance and benefits that were classified as restructuring charges, and other restructuring charges, respectively. Cumulative through the six months ended June 29, 2024, we recorded total charges for severance and benefits that were classified as restructuring charges, accelerated depreciation of property and equipment that was classified as restructuring charges, charges for inventory write down that was classified as cost of sales, and other restructuring of $9.9 million, $0.3 million, $0.3 million, and $0.3 million, respectively.

In the Structural Systems segment, we recorded $0.8 million and $0.4 million during the three months ended June 29, 2024 for severance and benefits that were classified as restructuring charges and other restructuring charges, respectively. We recorded charges of $1.0 million and $1.1 million during the six months ended June 29, 2024, for severance and benefits that were classified as restructuring charges, and other restructuring charges, respectively. Cumulative through the six months ended June 29, 2024, we recorded total charges for severance and benefits that were classified as restructuring charges, accelerated depreciation of property and equipment/impairment of property and equipment that was classified as restructuring charges, charges for inventory write down that was classified as cost of sales, and other restructuring of $6.9 million, $2.0 million, $1.4 million, and $3.9 million, respectively.

Our restructuring activities during the six months ended June 29, 2024 were as follows (in thousands):

	December 31, 2023		Six Months Ended June 29, 2024								June 29, 2024

Goodwill

Goodwill

We perform our annual goodwill impairment test as of the first day of the fourth quarter. If certain factors occur, including significant underperformance of our business relative to expected operating results, significant adverse economic and industry trends, a significant decline in our market capitalization for an extended period of time relative to net book value, a decision to divest individual businesses within a reporting unit, or a decision to group individual businesses differently, we may be required to perform an interim impairment test prior to the fourth quarter.

We may use either a qualitative or quantitative approach when testing a reporting unit’s goodwill for impairment. The qualitative approach for potential impairment analysis to determine whether it is more likely than not that the fair value of a reporting unit was less than its carrying amount.

The quantitative approach for potential impairment analysis is performed by comparing the fair value of a reporting unit to its carrying value, including goodwill. Fair value is estimated by management using a combination of the income approach (which is based on a discounted cash flow model) and market approach. Management’s cash flow projections include significant judgments and assumptions, including the amount and timing of expected cash flows, long-term growth rates, and discount rates. The cash flows used in the discounted cash flow model are based on our best estimate of future revenues, gross margins, and adjusted after-tax earnings. If any of these assumptions are incorrect, it will impact the estimated fair value of a reporting unit. The market approach also requires management judgment in selecting comparable business acquisitions and the transaction values observed and its related control premiums.

No material adverse factors/changes have occurred since the fourth quarter of 2023 that would require us to perform another qualitative or quantitative assessment. As such, for the second quarter of 2024, it was also not more likely than not that the fair values of the reporting units were less than their carrying amounts and thus, the respective goodwill amounts were not deemed to be impaired.

In April 2023, we completed the acquisition of BLR. The excess of the purchase price over the aggregate fair values of the net assets was recorded as goodwill. See Note 2 for further information.

The carrying amounts of our goodwill were as follows:

	(Dollars in thousands)

In July 2022, we completed a refinancing of all our existing debt by entering into a new term loan (“2022 Term Loan”) and a new revolving credit facility (“2022 Revolving Credit Facility”). The 2022 Term Loan is a $250.0 million senior secured loan that matures on July 14, 2027. The 2022 Revolving Credit Facility is a $200.0 million senior secured revolving credit facility that matures on July 14, 2027. The 2022 Term Loan and 2022 Revolving Credit Facility, collectively, represent our credit facilities (“2022 Credit Facilities”).

The 2022 Term Loan bears interest, at our option, at a rate equal to either (i) Term Secured Overnight Financing Rate (“Term SOFR”) plus an applicable margin ranging from 1.375% to 2.375% per year or (ii) Base Rate (defined as the highest of [a] Federal Funds Rate plus 0.50%, [b] Bank of America’s prime rate, and [c] Term SOFR plus 1.00%, and if the Base Rate is less than zero percent, it will be deemed zero percent) plus an applicable margin ranging from 0.375% to 1.375% per year, in each case based upon the consolidated total net adjusted leverage ratio. Interest payments are typically paid either on a monthly or quarterly basis, depending on the interest rate selected, on the last business day each month or quarter. In addition, the 2022 Term Loan requires quarterly amortization payments of 0.625% during year one and year two, 1.250% during year three and year four, and 1.875% during year five of the original outstanding principal balance of the 2022 Term Loan amount, on the last business day each quarter. The required quarterly amortization payments began in the fourth quarter of 2022.

The 2022 Revolving Credit Facility bears interest, at our option, at a rate equal to either (i) Term SOFR plus an applicable margin ranging from 1.375% to 2.375% per year or (ii) Base Rate (defined as the highest of [a] Federal Funds Rate plus 0.50%, [b] Bank of America’s prime rate, and [c] Term SOFR plus 1.00%, and if the Base Rate is less than zero percent, it will be deemed zero percent) plus an applicable margin ranging from 0.375% to 1.375% per year, in each case based upon the consolidated total net adjusted leverage ratio. Interest payments are typically paid on a monthly or quarterly basis, depending on the interest rate selected, on the last business day each month or quarter. The undrawn portion of the commitment of the 2022 Revolving Credit Facility is subject to a commitment fee ranging from 0.175% to 0.275%, based upon the consolidated total net adjusted leverage ratio, typically paid on a quarterly basis, on the last business day each quarter. However, the 2022 Revolving Credit Facility does not require any principal installment payments.

In conjunction with the closing of the 2022 Credit Facilities, we utilized the entire $250.0 million of proceeds from the 2022 Term Loan plus our existing cash on hand to pay off our entire debt balance outstanding of $254.2 million under our prior credit facilities.

For each of the three months ended June 29, 2024 and July 1, 2023, we made the required quarterly amortization payments on the 2022 Term Loan of $1.6 million. For each of the six months ended June 29, 2024 and July 1, 2023, we made the required amortization payments on the 2022 Term Loan totaling $3.1 million.

As of June 29, 2024, we had $176.0 million of unused borrowing capacity under the 2022 Revolving Credit Facility, after deducting $0.2 million for standby letters of credit.

As of June 29, 2024, we were in compliance with all covenants required under the 2022 Credit Facilities.

The 2022 Term Loan was considered a modification of debt for some lenders and an extinguishment of debt for other lenders, and thus, a loss of $0.2 million was recorded related to the extinguishment. In addition, the new fees incurred of $0.8 million were capitalized and will be amortized over the life of the 2022 Term Loan. Further, the remaining debt issuance costs related to the prior term loans of $1.0 million as of the modification date will be amortized over the life of the 2022 Term Loan, using the effective interest method.

The 2022 Revolving Credit Facility that replaced the prior revolving credit facility was considered a modification of debt except for the portion related to the creditor that is no longer a part of the 2022 Revolving Credit Facility and, in which case, it was considered an extinguishment of debt. As a result, we expensed the portion of the unamortized debt issuance costs related to the prior revolving credit facility that was considered an extinguishment of debt of $0.1 million. In addition, the new fees incurred of $1.7 million as part of the 2022 Revolving Credit Facility were capitalized and will be amortized over the life of the 2022 Revolving Credit Facility. Further, the remaining debt issuance costs related to the prior revolving credit facility of $0.8 million as of the modification date will also be amortized over the life of the 2022 Revolving Credit Facility.

The 2022 Credit Facilities were entered into by us (“Parent Company”) and guaranteed by all of our domestic subsidiaries, other than two subsidiaries that were considered minor (“Subsidiary Guarantors”). The Subsidiary Guarantors jointly and severally guarantee the 2022 Credit Facilities. The Parent Company has no independent assets or operations, and therefore, no consolidating financial information for the Parent Company and its subsidiaries is presented.

In April 2023, we completed the acquisition of BLR. The initial purchase price for BLR was $115.0 million, net of cash acquired, all payable in cash. We paid a gross aggregate of $117.0 million in cash upon the closing of the transaction. We utilized the 2022 Revolving Credit Facility to complete the acquisition. See Note 2 for further information.

In May 2023, we completed a public offering of our common stock resulting in net proceeds of $85.1 million. We utilized the net proceeds plus cash on hand to pay down $85.2 million on the 2022 Revolving Credit Facility. See Note 9 for further information.

In November 2021, we entered into derivative contracts, U.S. dollar-one month LIBOR forward interest rate swaps designated as cash flow hedges, all with an effective date of January 1, 2024, for an aggregate total notional amount of $150.0 million, weighted average fixed rate of 1.8%, and all terminating on January 1, 2031 (“Forward Interest Rate Swaps”). The Forward Interest Rate Swaps mature on a monthly basis, with fixed amount payer payment dates on the first day of each calendar month, commencing on February 1, 2024 through January 1, 2031. The Forward Interest Rate Swaps were deemed to be highly effective upon entering into the derivative contracts, and thus, hedge accounting treatment was utilized. Since the Amended Forward Interest Rate Swaps (as defined below) were not effective until January 1, 2024, we only recorded the changes in fair value of the derivative instruments that were highly effective and that were designated and qualified as cash flow hedges in other comprehensive income through December 31, 2023. See Note 1 and Note 4 for further information.

In July 2022, as a result of completing a refinancing of our existing debt, we were required to complete an amendment of the Forward Interest Rate Swaps (“Amended Forward Interest Rate Swaps”). The Forward Interest Rate Swaps were based on U.S. dollar-one month LIBOR and were amended to be based on one month Term SOFR as borrowings using LIBOR were no longer available under the 2022 Credit Facilities. Since this was an amendment of just the reference rate as a result of the cessation of LIBOR, utilizing the guidance under ASU 2020-04, we determined the Amended Forward Interest Rate Swaps as of the amendment date to continue to be highly effective. The Amended Forward Interest Rate Swaps weighted average fixed rate is 1.7%, as a result of the difference between U.S. dollar-one month LIBOR and one month Term SOFR.

In May 2023, we completed a public offering of 2.3 million shares of our common stock at $40.00 per share, for gross proceeds of $92.0 million. The common stock offering was made under our effective shelf registration statement. We incurred aggregate total out of pocket stock offering related fees of $6.9 million, resulting in net proceeds of $85.1 million. As such, we recorded an increase to common stock at par value of less than $0.1 million with the remaining amount as an increase to additional paid-in capital of $85.1 million. The net proceeds of the public stock offering along with cash on hand were used to pay down $85.2 million on the 2022 Revolving Credit Facility that was drawn on and utilized to complete the acquisition of BLR.

Indemnifications

Indemnifications

We have made guarantees and indemnities under which we may be required to make payments to a guaranteed or indemnified party, in relation to certain transactions, including revenue transactions in the ordinary course of business. Additionally, we indemnify our directors and officers to the maximum extent permitted under the laws of the State of Delaware and have a directors and officers insurance policy that may reduce our exposure in certain circumstances and may enable us to recover a portion of future amounts that may be payable, if any. Moreover, in connection with certain performance center leases, we have indemnified our lessors for certain claims arising from the performance center or the lease.

The duration of the guarantees and indemnities varies and, in many cases, is indefinite but subject to applicable statutes of limitations. The majority of guarantees and indemnities do not provide any limitations on the maximum potential future payments we could be obligated to make. Historically, payments related to these guarantees and indemnities have been immaterial. We estimate the fair value of our indemnification obligations as insignificant based on this history and insurance coverage and have, therefore, not recorded any liability for these guarantees and indemnities in the accompanying condensed consolidated balance sheets.

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

The provision for income taxes is determined using an estimated annual effective tax rate, which is generally less than the U.S. Federal statutory rate, primarily due to research and development (“R&D”) tax credits. Our effective tax rate may be subject to fluctuations during the year as new information is obtained, which may affect the assumptions used to estimate the annual effective tax rate, including factors such as expected utilization of R&D tax credits, valuation allowances against deferred tax assets, recognition or derecognition of tax benefits related to uncertain tax positions, and changes in or the interpretation of tax laws in jurisdictions where we conduct business. Also, excess tax benefits and tax detriments related to our equity compensation recognized in the condensed consolidated income statement could result in fluctuations in our effective tax rate period-over-period depending on the volatility of our stock price, number of restricted or performance stock units that vests, and stock options exercised during the period. We recognize deferred tax assets and liabilities, using enacted tax rates, for temporary differences between the financial reporting basis and the tax basis of our assets and liabilities along with net operating loss and tax credit carryovers.

We record a valuation allowance against our deferred tax assets to reduce the net carrying value to an amount that we believe is more likely than not to be realized. When we establish or reduce our valuation allowances against our deferred tax assets, the provision for income taxes will increase or decrease, respectively, in the period when that determination is made.

We recorded income tax expense of $2.2 million for the three months ended June 29, 2024 compared to $1.0 million for the three months ended July 1, 2023. The increase in income tax expense for the second quarter of 2024 compared to the second quarter of 2023 was primarily due to higher pre-tax income and higher income tax expense related to non-deductible book compensation expenses in the second quarter of 2024 compared to the second quarter of 2023. The increase in income tax expense was partially offset by higher income tax benefits related to the U.S. Federal research and development credit recognized in the second quarter of 2024 compared to the second quarter of 2023.

We recorded income tax expense of $4.1 million for the six months ended June 29, 2024 compared to $1.8 million for the six months ended July 1, 2023. The increase in income tax expense for the six months ended June 29, 2024 compared to the six months ended July 1, 2023 was primarily due to higher pre-tax income and higher income tax expense related to non-deductible book compensation expenses in the six months ended June 29, 2024 compared to the six months ended July 1, 2023. The increase in income tax expense was partially offset by higher income tax benefits related to the U.S. Federal research and development credit recognized in the six months ended June 29, 2024 compared to the six months ended July 1, 2023.

Our total amount of unrecognized tax benefits was $4.8 million and $4.5 million as of June 29, 2024 and December 31, 2023, respectively. If recognized, $3.0 million would affect the effective tax rate. We record interest and penalty charges, if any, related to uncertain tax positions as a component of tax expense and unrecognized tax benefits. The amounts accrued for interest and penalty charges as of June 29, 2024 and December 31, 2023 were not significant. As a result of statute of limitations set to expire in the fourth quarter of 2024, we expect decreases to our unrecognized tax benefits of approximately $1.0 million in the next twelve months.

We file U.S. Federal and state income tax returns. We are subject to examination by the Internal Revenue Service (“IRS”) for tax years after 2019 and by state taxing authorities for tax years after 2018. While we are no longer subject to examination prior to those periods, carryforwards generated prior to those periods may still be adjusted upon examination by the IRS or state taxing authorities if they either have been or will be used in a subsequent period. We believe we have adequately accrued for tax deficiencies or reductions in tax benefits, if any, that could result from the examination and all open audit years.

California’s Wage and Hour Laws Complaint

In December 2020, a representative action under California’s Private Attorneys General Act was filed against us in the Superior Court for the State of California, County of San Bernardino. We received service of process of this complaint in January 2021. The complaint alleged violations of California’s wage and hour laws relating to our current and former employees and sought attorney’s fees and penalties. We vigorously refuted and defended against these claims and reached a tentative settlement of $0.8 million during the fourth quarter 2021, which was subject to court approval. Thus, we recorded accrued liabilities of $0.8 million as of December 31, 2021. During the second quarter of 2022, additional factual information was identified resulting in an increase in the amount of the tentative settlement to $0.9 million. Therefore, we recorded an additional accrued liabilities of $0.1 million for a total accrued liabilities amount of $0.9 million as of the end of the second quarter of 2022 which remained unchanged as of December 31, 2022 as we were awaiting final court approval of this settlement. Subsequent to final court approval and paying of the $0.9 million in January 2023, during the third quarter of 2023 and upon plaintiff's motion, the court re-opened the settlement agreement to determine whether the class list captured all affected employees. We are appealing this decision and intend to defend our position vigorously. Any amount of additional liability is still undetermined pending the appeal and as such, there is no amount of loss that is probable and reasonably estimable at this time. Thus, no additional accrual was recorded during the three and six months ended June 29, 2024.

Groundwater

Structural Systems has been directed by California environmental agencies to investigate and take corrective action for groundwater contamination at our facilities located in El Mirage and Monrovia, California. Based on currently available information, we have established an accrual for its estimated liability for such investigation and corrective action of $1.5 million at both June 29, 2024 and December 31, 2023, which is reflected in other long-term liabilities on our condensed consolidated balance sheets.

Waste Disposal

Structural Systems also faces liability as a potentially responsible party for hazardous waste disposed at landfills located in Casmalia and West Covina, California. Structural Systems and other companies and government entities have entered into consent decrees with respect to these landfills with the United States Environmental Protection Agency and/or California environmental agencies under which certain investigation, remediation and maintenance activities are being performed. Based on currently available information, we preliminarily estimate that the range of our future liabilities in connection with the landfill located in West Covina, California is between $0.4 million and $3.1 million. We have established an accrual for the estimated liability in connection with the West Covina landfill of $0.4 million as of both June 29, 2024 and December 31, 2023, which is reflected in other long-term liabilities on our condensed consolidated balance sheets. Our ultimate liability in connection with these matters will depend upon a number of factors, including changes in existing laws and regulations, the design and cost of construction, operation and maintenance activities, and the allocation of liability among potentially responsible parties.

Guaymas Performance Center Fire

In June 2020, a fire severely damaged our performance center in Guaymas, Mexico, which is part of our Structural Systems segment. There were no injuries; however, property and equipment, inventories, and tooling in this leased facility were damaged. Our Guaymas performance center, comprised of two buildings with an aggregate total of 62,000 square feet, was severely damaged. The loss of production from the Guaymas performance center was absorbed by our other existing performance centers; however, we have reestablished our operations and are in the process of certification with various customers and ramping up our manufacturing capabilities in a different leased facility with 117,000 square feet in Guaymas. A neighboring, non-related manufacturing facility, also suffered fire damage during the same time as the fire that severely damaged our Guaymas performance center, and in November 2023, the occupant of the neighboring facility filed suit against us in U.S. District Court for the Central District of California seeking unspecified amounts for damages relating to the fire. In addition, subsequent to the quarter end, we received a subrogation demand from our landlord’s insurer, which we are currently evaluating. We intend to defend these matters vigorously and believe we have substantial defenses in relation to these claims. As responsibility for the fire is still undetermined, there is no amount of loss that is probable and reasonably estimable at this time. If we are ultimately deemed to be responsible or party responsible, it is possible we could incur a loss in excess of our insurance coverage limits, which could be material to our cash flow, liquidity, or financial results.

Our insurance covers damage, up to a capped amount, to the facility, equipment, unfinished inventory, and other assets at replacement cost, finished goods inventory at selling price, as well as business interruption, third party property damage, and recovery related expenses caused by the fire, less our per claim deductible. The anticipated insurance recoveries related to losses and incremental costs incurred are recognized when receipt is probable. The anticipated insurance recoveries in excess of net book value of the damaged operating assets and business interruption are not recorded until all contingencies related to our

claim have been resolved.

The insurance claim for damages to our operating assets and business interruption was deemed final and closed by our insurance company during the three months ended July 1, 2023. Thus, the final $3.8 million of insurance recoveries were also received and recorded as other income during the three months ended July 1, 2023. In addition, the remaining general insurance recoveries that were received in 2020 of $3.9 million, but recognition was deferred until all the gain contingencies were resolved, such gain contingencies were deemed resolved and thus, recorded as other income during the three months ended July 1, 2023. Cumulatively, as of July 1, 2023, we received insurance recoveries in aggregate total of $23.7 million, with $7.5 million for business interruption and $16.2 million for damages to property and equipment, inventories, and tooling. Further, all insurance recovery amounts received related to this claim have been recognized up to the amount of net book value loss and presented within the same financial statement line item in the condensed consolidated statements of income resulting in no net impact, with the remaining amounts recognized as other income in our condensed consolidated statements of income when the contingencies were deemed resolved.

Other Structural Systems Performance Center Fire

In April 2023, a fire damaged a relatively small portion of one of our performance centers in our Structural Systems reporting segment. There were no injuries; however, subsequent to the fire, we determined that some property and equipment in this company-owned facility were damaged. Our insurance covers damage, up to a capped amount, to the property and equipment at replacement cost, as well as business interruption and recovery related expenses caused by the fire, less our per claim deductible. There was a loss of production in this damaged portion of the performance center for a short period of time, but the incident did not otherwise result in significant disruption to customer delivery schedules. Production in this damaged portion resumed later that same quarter. As such, during the three months ended July 1, 2023, we wrote off property and equipment with an aggregate total net book value of $0.2 million. Also during the three months ended July 1, 2023, we received insurance recoveries of $0.3 million (which was net of our deductible of $0.1 million) and thus, such insurance recoveries were also presented within the same financial statement line item in the condensed consolidated statements of income resulting in no net impact. The amount of the insurance recoveries received in excess of the loss on operating assets was deemed a contingent gain, and since the gain contingencies were deemed resolved, the $0.1 million was also recorded as other income during the three months ended July 1, 2023. Finally, during the three months ended December 31, 2023, the insurance claim was deemed final and closed by our insurance company and we received a final payment of $0.3 million, which was recorded as other income.

Real Estate Obligations

Real estate obligations, which include legally binding minimum lease payments for an executed lease that had not yet commenced, were $5.8 million as of June 29, 2024, and will be paid over the lease term of 10 years.

In the normal course of business, Ducommun and its subsidiaries are defendants in certain other litigation, claims and inquiries, including matters relating to environmental laws. In addition, Ducommun makes various commitments and incurs contingent liabilities in the ordinary course of business. While it is not feasible to predict the outcome of these matters, Ducommun does not presently expect that any sum it may be required to pay in connection with these matters would have a material adverse effect on its condensed consolidated financial position, results of operations or cash flows.

Summary of Significant Accounting Policies (Policies)

6 Months Ended

Jun. 29, 2024

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The unaudited condensed consolidated financial statements include the accounts of Ducommun Incorporated and its subsidiaries (“Ducommun,” the “Company,” “we,” “us” or “our”), after eliminating intercompany balances and transactions. The December 31, 2023 condensed consolidated balance sheet data was derived from audited financial statements, but does not contain all disclosures required by accounting principles generally accepted in the United States of America (“GAAP”).

Our significant accounting policies were described in Part IV, Item 15(a)(1), “Note 1. Summary of Significant Accounting Policies” in our Annual Report on Form 10-K for the year ended December 31, 2023 (“2023 Form 10-K”). The financial information included in this Quarterly Report on Form 10-Q (“Form 10-Q”) should be read in conjunction with the 2023 Form 10-K.

In the opinion of management, all adjustments, including recurring accruals, have been made that are necessary to fairly state our condensed consolidated financial position, statements of income, comprehensive income, changes in shareholders’ equity, and cash flows in accordance with GAAP for the periods covered by this Form 10-Q. The results of operations for the three and six months ended June 29, 2024 are not necessarily indicative of the results to be expected for the full year ending December 31, 2024.

Our fiscal quarters typically end on the Saturday closest to the end of March, June and September for the first three fiscal quarters of each year, and on December 31 for our fourth fiscal quarter. As a result of using fiscal quarters for the first three quarters combined with leap years, our first and fourth fiscal quarters can range between 12 1/2 weeks to 13 1/2 weeks while the second and third fiscal quarters remain at a constant 13 weeks per fiscal quarter.

Use of Estimates

Use of Estimates

Certain amounts and disclosures included in the unaudited condensed consolidated financial statements require management to make estimates and judgments that affect the amounts of assets, liabilities (including contract liabilities), revenues and expenses, and related disclosures of contingent assets and liabilities. These estimates are based on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates.

Earnings Per Share

Earnings Per Share

Basic earnings per share are computed by dividing income available to common shareholders by the weighted-average number of common shares outstanding in each period. Diluted earnings per share is computed by dividing income available to common shareholders by the weighted-average number of common shares outstanding, plus any potentially dilutive shares that could be issued if exercised or converted into common stock in each period.

Fair Value

Fair Value

Assets and liabilities that are measured, recorded or disclosed at fair value on a recurring basis are categorized using the fair value hierarchy. The fair value hierarchy has three levels based on the reliability of the inputs used to determine the fair value. Level 1, the highest level, refers to the values determined based on quoted prices in active markets for identical assets. Level 2 refers to fair values estimated using significant observable inputs. Level 3, the lowest level, includes fair values estimated using significant unobservable inputs.

We have money market funds which are included as cash and cash equivalents. We also have forward interest rate swap agreements and the fair value of the forward interest rate swap agreements was determined using pricing models that use observable market inputs as of the balance sheet date, a Level 2 measurement.

Cash and Cash Equivalents

Cash and Cash Equivalents

Cash equivalents consist of highly liquid instruments purchased with original maturities of three months or less. These assets are valued at cost, which approximates fair value, and we classify as Level 1.

Derivative Instruments

Derivative Instruments

We recognize derivative instruments on our condensed consolidated balance sheets at their fair value. On the date that we enter into a derivative contract, we designate the derivative instrument as a fair value hedge, a cash flow hedge, or a derivative instrument that will not be accounted for using hedge accounting methods. In November 2021, we entered into forward interest rate swap agreements with an aggregate notional amount of $150.0 million, all with an effective date of January 1, 2024 (“Forward Interest Rate Swaps”), to manage our exposure to interest rate movements on a portion of our debt. At the time we entered into the Forward Interest Rate Swaps, there was a high probability of forecasted interest payments on our debts occurring and the swaps were highly effective in offsetting those interest payments; therefore, we elected to apply cash flow hedge accounting. In July 2022, as a result of refinancing all our existing debt, which allowed borrowing based on a Secured Overnight Financing Rate (“SOFR”), we were required to complete an amendment of the Forward Interest Rate Swaps from One Month London Interbank Offered Rate (“LIBOR”) to One Month Term SOFR (“Amended Forward Interest Rate Swaps”), which occurred on the same day. After the transition of the Forward Interest Rate Swaps and debt to SOFR was completed, we determined the hedging relationships were still highly effective as of the amendment date. See Note 4 and Note 8. As of June 29, 2024, all of our derivative instruments were designated as cash flow hedges.

We record changes in the fair value of a derivative instrument that is highly effective and that is designated and qualifies as a cash flow hedge in other comprehensive income (loss), net of tax until our earnings are affected by the variability of cash flows of the underlying hedged item. We report changes in the fair values of derivative instruments that are not designated or do not qualify for hedge accounting in current period earnings. We classify cash flows from derivative instruments in the condensed consolidated statements of cash flows in the same category as the item being hedged or on a basis consistent with the nature of the instrument. Prior to the Amended Forward Interest Rate Swaps being effective on January 1, 2024, we only recorded the changes in fair value of the derivative instruments that were highly effective and that were designated and qualified as cash flow hedges prior to the effective date. See Note 4.

When we determine that a derivative instrument is not highly effective as a hedge, we discontinue hedge accounting prospectively. In all situations in which we discontinue hedge accounting and the derivative instrument remains outstanding, we will carry the derivative instrument at its fair value on our condensed consolidated balance sheets and recognize subsequent changes in its fair value in our current period earnings.

Inventories

Inventories

Inventories are stated at the lower of cost or net realizable value with cost being determined using a moving average cost basis for raw materials and actual cost for work-in-process and finished goods. The majority of our inventory is charged to cost of sales as raw materials are placed into production. Inventoried costs include raw materials, outside processing, direct labor and allocated overhead, adjusted for any abnormal amounts of idle performance center expense, freight, handling costs, and wasted materials (spoilage) incurred. We assess the inventory carrying value and reduce it, if necessary, to its net realizable value based on customer orders on hand, and internal demand forecasts using management’s best estimates given information currently available. The majority of our revenues are recognized over time, however, for revenue contracts where revenue is recognized using the point in time method, inventory is not reduced until it is shipped or transfer of control to the customer has occurred. Our ending inventory consists of raw materials, work-in-process, and finished goods.

Accumulated Other Comprehensive Income

Accumulated Other Comprehensive Income

Accumulated other comprehensive income, as reflected on the condensed consolidated balance sheets under the equity section, was comprised of cumulative pension and retirement liability adjustments, net of tax, and change in net unrealized gains and losses on cash flow hedges, net of tax.

Revenue Recognition

Revenue Recognition

Our customers typically engage us to manufacture products based on designs and specifications provided by the end-use customer. This requires the building of tooling and manufacturing first article inspection products (prototypes) before volume manufacturing. Contracts with our customers generally include a termination for convenience clause.

We have a significant number of contracts that are started and completed within the same year, as well as contracts derived from long-term agreements and programs that can span several years. We recognize revenue under ASC 606, “Revenue from Contracts with Customers” (“ASC 606”), which utilizes a five-step model.

The definition of a contract for us is typically defined as a customer purchase order as this is when we achieve an enforceable right to payment. The majority of our contracts are firm fixed-price contracts. The deliverables within a customer purchase order are analyzed to determine the number of performance obligations. In addition, at times, in order to achieve economies of scale and based on our customer’s forecasted demand, we may build in advance of receiving a purchase order from our customer. When that occurs, we would not recognize revenue until we have received the customer purchase order.

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account under ASC 606. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, control is transferred and the performance obligation is satisfied. The majority of our contracts have a single performance obligation as the promise to transfer the individual goods or services are highly interrelated or met the series guidance. For contracts with multiple performance obligations, we allocate the contract transaction price to each performance obligation using our best estimate of the standalone selling price of each distinct good or service in the contract. The primary method used to estimate the standalone selling price is the expected cost plus a margin approach, under which we forecast our expected costs of satisfying a performance obligation and then add an appropriate margin for that distinct good or service.

We manufacture most products to customer specifications, and the product cannot be easily modified for another customer. As such, these products are deemed to have no alternative use once the manufacturing process begins. In the event the customer invokes a termination for convenience clause, we would be entitled to costs incurred to date plus a reasonable profit. Contract costs typically include labor, materials, overhead, and when applicable, subcontractor costs. For most of our products, we are building assets with no alternative use and have enforceable right to payment, and thus, we recognize revenue using the over time method.

The majority of our performance obligations are satisfied over time as work progresses. Typically, revenue is recognized over time using an input measure (i.e., costs incurred to date relative to total estimated costs at completion, also known as cost-to-cost plus reasonable profit) to measure progress. Our typical revenue contract is a firm fixed price contract, and the cost of raw materials could make up a significant amount of the total costs incurred. As such, we believe using the total costs incurred input method would be the most appropriate method. While the cost of raw materials could make up a significant amount of the total costs incurred, there is a direct relationship between our inputs and the transfer of control of goods or services to the customer.

Contract estimates, known as estimates at completion, are based on various assumptions to project the outcome of future events that can span multiple months or years. These assumptions include among others, labor productivity and availability; the complexity of the work to be performed; the cost and availability of materials; overhead cost rates; and the performance of subcontractors. As a significant change in one or more of these estimates could affect the progress completed (and related profitability) on our contracts, we review and update our contract-related estimates on a regular basis. We recognize such adjustments under the cumulative catch-up method. Under this method, the impact of the adjustment is recognized in the period the adjustment is identified. In any given reporting period, we have a large number of active contracts, which we have defined as a customer purchase order, and changes in estimates may occur on a significant number of these contracts. Given the significant number of contracts that we may have at any given point in time, the varied nature of products produced under such contracts, and the different assumptions, facts and circumstances associated with each individual contract, and the fact that such changes at the contract level are typically not material, we disclose cumulative catch-up adjustments on a net basis.

Recent Accounting Pronouncements and Recently Issued Accounting Standards

Recent Accounting Pronouncements

Recently Issued Accounting Standards

In March 2024, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2024-02, “Codification Improvements - Amendments to Remove References to the Concepts Statements” (“ASU 2024-02”), which removed references to various FASB Concepts Statements and updates technical corrections such as conforming amendments, clarification to guidance, simplifications to wording or the structure of guidance, and other minor improvements. The new guidance is effective for fiscal years beginning after December 15, 2024, which is our annual period beginning January 1, 2025. Early adoption is permitted. We are evaluating the impact of this standard.

In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“ASU 2023-09”), which provides more transparency about tax information primarily related to the rate reconciliation and the income taxes paid. The new guidance is effective for fiscal years beginning after December 15, 2024, which will be our annual period beginning January 1, 2025. Early adoption is permitted. We are evaluating the impact of this standard.

In November 2023, the FASB issued ASU 2023-07, “Segment Reporting (Topic 280), Improvements to Reportable Segment Disclosures” (“ASU 2023-07”), which expands reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The new guidance is effective for fiscal years beginning after December 15, 2023, which is our annual period beginning January 1, 2024, and interim periods within fiscal years beginning after December 15, 2024, which will be our interim period beginning January 1, 2025. Early adoption is permitted. We are evaluating the impact of this standard.

In October 2023, the FASB issued ASU 2023-06, “Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative” (“ASU 2023-06”), which incorporates updates to the Accounting Standards Codification to align certain SEC disclosure requirements. The amendments impact a variety of topics but are relatively narrow in nature. For entities required to comply with the SEC’s existing disclosure requirements, the effective date for each amendment will be the effective date of the removal of the disclosure requirement from SEC Regulation S-X or SEC Regulation S-K, with early adoption prohibited. The amendments should be applied prospectively. We are evaluating the impact of this standard.
