**NEWS RELEASE**

**Ducommun Incorporated Reports**

**Fourth Quarter 2025 Results**

*Strong Finish to 2025; Record Full Year Revenue and Gross Margins*

COSTA MESA, CALIFORNIA (February 26, 2026) – Ducommun Incorporated (NYSE: DCO) ("Ducommun" or the "Company") today reported results for its fourth quarter and year ended December 31, 2025.

**Fourth Quarter 2025 Recap**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net revenue of $215.8 million, an increase of 9.4% over Q4 2024

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Gross margin of 27.7% showed year-over-year growth of 420 bps

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net income of $7.4 million increased 10% year-over-year, or $0.48 per diluted share, or 3.4% of revenue

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Non-GAAP adjusted net income for the quarter of $16.2 million which increased 43% year-over-year, or $1.05 per diluted share

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Adjusted EBITDA of $37.9 million (increase of 39% year-over-year), or 17.5% of revenue, up 370 bps year-over-year

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Revenue Remaining Performance Obligations ("RPO") at a new record of $1.1 billion with book-to-bill ratio of 1.3x

"We continued to make excellent progress to close out year three of our five year VISION 2027 with gross margin and Adjusted EBITDA margins at record levels along with Engineered Products at 23% of our revenue mix. In addition, I am very happy to report that in 2025, the Company set a new record for revenue for the third consecutive year, exceeding $800 million for the first time, and getting to $825 million for 2025. In Q4, net revenue grew 9.4% to a new quarterly record of $215.8 million, led by our military and space business," said Stephen G. Oswald, chairman, president and chief executive officer. "Our defense business was fueled by growth in DCO's missiles platforms, fixed-wing aircraft and rotorcraft platforms. Book-to-bill remained strong during the quarter at 1.3x with orders from missile components driving bookings. With the Department of War's focus on ramping up production and long-term agreements now in place with RTX, our largest customer and Lockheed, we expect our missile franchise to continue to gain strength in 2026 and beyond.

"Ducommun also continues to make strong progress in its margin expansion journey with quarterly gross margins expanding 420 bps year-over-year to 27.7%, and full year gross margins at 26.9%, both new records for us. Adjusted EBITDA margins as well benefited from favorable product mix, expanding 370 bps year-over-year to 17.5%, with full year 2025 Adjusted EBITDA margins at 16.4%. Solid progress continues towards our VISION 2027 commitment of 18% Adjusted EBITDA with eight quarters to go.

"The tariff environment has not had a material impact on our financial results thus far and with the recent Supreme Court decision, it further mitigates risk on this front. At this time, we do not expect tariffs to have any material impact on our financial outlook. Ducommun is largely a U.S. manufacturer with U.S. workers and our domestic facilities generate more than 95% of Ducommun's revenue. We are also making progress in mitigating raw materials tariff exposures through either duty exemptions on military products or by passing through to our customers under the terms of our contracts.

"In summary, Q4 was another strong performance for our team and 2025 was another record year for the Company. With Boeing continuing to make significant progress on their production rate ramp and destocking headwinds easing through 2026, our commercial aerospace business is better positioned in the back half of this year and

------

beyond. Growth in defense spending, particularly the significant ramp in missile production activity will be a boost for our military and space segment in 2026 and several years after that. These drivers accompanied by our continued work to expand margins positions us and the DCO shareholder very well going forward."

**Fourth Quarter Results**

Net revenue for the fourth quarter of 2025 was $215.8 million, compared to $197.3 million for the fourth quarter of 2024. The 9.4% increase year-over-year was primarily due to the following in the Company's key end-use markets:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $14.7 million higher revenue within the Company's military and space end-use markets due to higher rates on selected fixed-wing and rotary-wing aircraft platforms, a classified program, and missile platforms, partially offset by lower rates on electronic warfare platforms; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $0.5 million higher revenue within the Company's commercial aerospace end-use markets due to growth in Airbus and higher revenues from in-flight entertainment, partially offset by lower revenues from Boeing on the 737 MAX.

In addition, revenue for the Company's industrial end-use markets for the fourth quarter of 2025 increased $3.3 million compared to the fourth quarter of 2024 mainly due to restocking and last time buys.

Remaining Performance Obligations as of December 31, 2025 reached a new record of $1,106.0 million driven by strong bookings during the quarter and a book-to-bill ratio of 1.3x. Bookings were driven by strong order flow for missile platforms.

Net income for the fourth quarter of 2025 was $7.4 million, or $0.48 per diluted share, compared to $6.8 million, or $0.45 per diluted share, for the fourth quarter of 2024. This reflects higher gross profit of $13.4 million, partially offset by higher litigation settlement and related costs of $7.6 million, higher selling, general and administrative ("SG&A") expenses of $3.4 million, and higher income tax expense of $2.5 million. Non-GAAP adjusted net income for the fourth quarter of 2025 was $16.2 million, or $1.05 per diluted share, compared to $11.4 million, or $0.75 per diluted share for the fourth quarter of 2024.

Gross profit for the fourth quarter of 2025 was $59.8 million, or 27.7% of revenue, compared to gross profit of $46.4 million, or 23.5% of revenue, for the fourth quarter of 2024. The increase in gross margin percentage year-over-year was primarily due to higher manufacturing volume and favorable product mix, partially offset by lower restructuring and other one-time charges related to the shutdown of the Company's Monrovia performance center.

Operating income for the fourth quarter of 2025 was $14.0 million, or 6.5% of revenue, compared to $10.4 million, or 5.3% of revenue, in the comparable period last year. The year-over-year increase was primarily due to higher gross profit noted above, partially offset by higher litigation settlement and related costs and higher SG&A expenses. Non-GAAP adjusted operating income for the fourth quarter of 2025 was $24.6 million, or 11.4% of revenue, compared to $16.1 million, or 8.2% of revenue, in the comparable period last year.

Interest expense for the fourth quarter of 2025 was $3.5 million compared to $3.6 million in the comparable period of 2024. The year-over-year decrease was primarily due to lower interest rates partially offset by a higher debt balance in the fourth quarter of 2025.

Adjusted EBITDA for the fourth quarter of 2025 was $37.9 million, or 17.5% of revenue, compared to $27.3 million, or 13.8% of revenue, for the comparable period in 2024.

During the fourth quarter of 2025, the net cash used in operations was $74.7 million compared to net cash provided by operations of $18.4 million during the fourth quarter of 2024. The lower net cash provided by operations year-over-year was primarily due to litigation settlement and related costs, net, higher accounts receivable, and lower accounts payable, partially offset by lower inventories and higher contract liabilities. Due to the size and one-time nature of litigation settlement and related payments made during the fourth quarter of 2025, the Company is disclosing Non-GAAP adjusted cash flow from operations. Non-GAAP adjusted net cash provided by operating activities was $26.5 million during the fourth quarter of 2025 compared to $18.4 million during the fourth quarter of 2024.

**Business Segment Information**

<u>Electronic Systems</u>

Electronic Systems reported net revenue for the current quarter of $119.6 million, compared to $107.0 million for the fourth quarter of 2024. The year-over-year increase was primarily due to the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $9.4 million higher revenue within the Company's military and space end-use markets due to higher rates on selected fixed-wing aircraft, a classified program, and missile platforms, partially offset by lower rates on electronic warfare platforms; partially offset by

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $0.1 million lower revenue within the Company's commercial aerospace end-use markets due to lower rates on large commercial aircraft platforms, partially offset by higher revenues from in-flight entertainment.

In addition, revenue for the Company's industrial end-use markets for the fourth quarter of 2025 increased $3.3 million compared to the fourth quarter of 2024 mainly due to restocking and last time buys.

Electronic Systems operating income for the current year fourth quarter was $22.0 million, or 18.4% of revenue, compared to $19.0 million, or 17.7% of revenue, for the comparable quarter in 2024. The year-over-year increase was primarily due to higher manufacturing volume and favorable product mix, partially offset by higher other manufacturing costs.

<u>Structural Systems</u>

Structural Systems reported net revenue for the current quarter of $96.2 million, compared to $90.3 million for the fourth quarter of 2024. The year-over-year increase was primarily due to the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $5.3 million higher revenue within the Company's military and space end-use markets due to higher rates on selected rotary-wing aircraft and fixed-wing aircraft platforms; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $0.5 million higher revenue within the Company's commercial aerospace end-use markets due to growth in Airbus, partially offset by lower revenues from Boeing on the 737 MAX.

Non-GAAP adjusted operating income for the fourth quarter of 2025 was $17.2 million, or 17.8% of revenue, compared to $8.3 million, or 9.2% of revenue, in the comparable period last year.

<u>Corporate General and Administrative ("CG&A") Expense</u>

CG&A expense for the fourth quarter of 2025 was $22.5 million, or 10.4% of total Company revenue, compared to $11.8 million, or 6.0% of total Company revenue, in the comparable quarter in the prior year. The year-over-year increase in CG&A expenses was primarily due to higher litigation settlement and related costs of $7.6 million, higher stock-based compensation expense of $1.9 million, and higher compensation and benefits costs of $1.3 million, partially offset by lower professional services fees of $0.9 million. Non-GAAP adjusted CG&A expense excluding litigation settlement and related costs for the fourth quarter of 2025 was $14.9 million compared to $11.8 million for the fourth quarter of 2024.

The Company generally uses the words "may," "will," "could," "expect," "anticipate," "believe," "estimate," "plan," "intend," "continue" and similar expressions in this press release and any attachments to identify forward-looking statements. The Company bases these forward-looking statements on its current views with respect to future events and financial performance. Actual results could differ materially from those projected in the forward-looking statements. These forward-looking statements are subject to risks, uncertainties and assumptions, including, among other things: the cyclicality of our end-use markets, the level of U.S. government defense spending, our customers may experience changes in production rates or delays in the launch and certification of new products, timing of orders from our customers which are subject to cancellation, modification or rescheduling, our ability to obtain additional financing and service existing debt to fund capital expenditures and meet our working capital needs, legal and regulatory risks, including pending litigation matters generally and as well as any potential losses arising from third party subrogation claims related to the Guaymas performance center fire that may become material, the cost of expansion, consolidation and acquisitions, competition, economic and geopolitical developments – including supply chain issues, our ability to successfully implement restructuring, realignment and cost reduction activities that could adversely impact our ability to achieve our strategic objectives, international trade restrictions and our ability to obtain necessary U.S. government approvals for proposed sales to certain foreign customers, the impact of tariffs and elevated interest rates, risks associated with a prolonged partial or total U.S. federal government shutdown, the ability to attract and retain key personnel and avoid labor disruptions, the ability to adequately protect and enforce intellectual property rights, pandemics, disasters – natural or otherwise, and risk of cybersecurity attacks and other risks and uncertainties, including those detailed from time to time in the Company's periodic reports filed with the Securities and Exchange Commission.

**<u>Note Regarding Non-GAAP Financial Information</u>**

This release contains non-GAAP financial measures, including Adjusted EBITDA (which excludes interest expense, income tax expense (benefit), depreciation, amortization, stock-based compensation expense, restructuring charges, professional fees related to unsolicited non-binding acquisition offer, litigation settlement and related costs, net, loss extinguishment of debt, other debt refinancing costs, gain on sale of property and other assets, and inventory purchase accounting adjustments), including as a percentage of net revenues, non-GAAP operating income, including as a percentage of net revenues, non-GAAP net income, non-GAAP diluted earnings per share, non-GAAP cash flow from operating activities, and backlog. In addition, certain other prior period amounts have been reclassified to conform to current year's presentation.

The Company believes the presentation of these non-GAAP measures provide important supplemental information to management and investors regarding financial and business trends relating to its financial condition and results of operations. The Company's management uses these non-GAAP financial measures along with the most directly comparable GAAP financial measures in evaluating the Company's actual and forecasted operating performance, capital resources and cash flow. The non-GAAP financial information presented herein should be considered supplemental to, and not as a substitute for, or superior to, financial measures calculated in accordance with GAAP. The Company discloses different non-GAAP financial measures in order to provide greater transparency and to help the Company's investors to more meaningfully evaluate and compare Ducommun's results to its previously reported results. The non-GAAP financial measures that the Company uses may not be comparable to similarly titled financial measures used by other companies.

The Company defines backlog as customer placed purchase orders 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 herein may or may not be greater than the remaining performance obligations disclosed under ASC 606. Backlog is subject to delivery delays or program cancellations, which are beyond the Company's control. Backlog is affected by timing differences in the placement of customer orders and tends to be concentrated in some of the Company's programs.
