**NEWS RELEASE**

**Ducommun Incorporated Reports**

**First Quarter 2026 Results**

*New Record for Q1 Revenue, Strong Gross Margins and Net Income*

COSTA MESA, CALIFORNIA (May 12, 2026) – Ducommun Incorporated (NYSE: DCO) ("Ducommun" or the "Company") today reported results for its first quarter ended April 4, 2026.

**First Quarter 2026 Recap**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net Revenue was $209.0 million, an increase of 9% over Q1 2025\*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Gross margin of 26.9%, year-over-year growth of 70 bps

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net income of $9.9 million (increase of 607% year-over-year) or $0.64 per diluted share, and 4.7% of revenue, up 400 bps year-over-year

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Non-GAAP adjusted net income of $11.7 million (increase of 232% year-over-year), or $0.75 per diluted share

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Adjusted EBITDA of $35.4 million (increase of 19% year-over-year), or 16.9% of revenue, up 150 bps year-over-year

"An excellent quarter and strong start to 2026 for Ducommun. Our team continued to make great progress towards our VISION 2027 goals with another record for revenue during the first quarter along with strong gross margin and Adjusted EBITDA margins. Net revenue grew a very healthy 9%, led by strength in commercial aerospace which we have been waiting for, along with gains in our defense business," said Stephen G. Oswald, chairman, president and chief executive officer. "Significant growth in single-aisle demand for Airbus A220, A320, and Boeing 737 MAX along with commercial rotorcraft resulted in 18% year-over-year growth in our commercial aerospace business which was a very nice rebound. Ducommun's defense business saw growth yet again with our missile franchise specifically the Patriot missile platform being a highlight along with good growth on fixed-wing aircraft platforms including the F35 and the F-15.

"The Company continues to make solid progress as well with its margin expansion journey started back in 2023 with gross margins expanding 70 bps year-over-year to 26.9%. Adjusted EBITDA exceeded $30 million for the fourth consecutive quarter, expanding 150 bps year-over-year from 15.4% to 16.9% and keeping us on a good pace to meet the VISION 2027 financial goal of 18% Adjusted EBITDA and with seven quarters remaining, we have high confidence.

"I also look at the Q1 results as a very healthy start to the fourth year of our VISION 2027 plan, especially in commercial aerospace. While we expect to see some destocking headwinds in the remaining quarters of 2026, the outlook is very promising, especially in 2027 and 2028. Ducommun's strong missile franchise should also continue to gather momentum throughout the year as we are well positioned to benefit from the Department of War's long-term 7 year framework agreements for key missile programs with defense primes including RTX, our largest customer and Lockheed Martin."

**First Quarter Results**

Net revenue for the first quarter of 2026 was $209.0 million compared to $192.5 million for the first quarter of 2025. The year-over-year increase was primarily due to the following in the Company's key end-use markets:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $12.5 million higher revenue in the Company's commercial aerospace end-use markets due to higher rates on large aircraft and rotary-wing aircraft platforms; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $5.4 million higher revenue in the Company's military and space end-use markets due to higher rates on selected fixed-wing aircraft and missiles platforms, partially offset by lower rates on electronic warfare, ground vehicle weapons, and radar platforms.

In addition, revenue for the Company's industrial end-use markets for the first quarter of 2026 decreased $1.4 million compared to the first quarter of 2025 mainly due to timing of orders.

Net income for the first quarter of 2026 was $9.9 million, or 4.7% of revenue, or $0.64 per diluted share, compared to net income of $1.4 million, or 0.7% revenue, or $0.09 per diluted share, for the first quarter of 2025. This reflects higher gross profit of $5.8 million and lower stock-based compensation expense of $4.3 million, partially offset by higher income tax expense of $1.5 million.

Gross profit for the first quarter of 2026 was $56.2 million, or 26.9% of revenue, compared to gross profit of $50.5 million, or 26.2% of revenue, for the first quarter of 2025. The increase in gross profit as a percentage of net revenue year-over-year was primarily due to lower other manufacturing costs, favorable product mix, and higher manufacturing volume.

Operating income for the first quarter of 2026 was $15.7 million, or 7.5% of revenue, compared to operating income of $5.0 million, or 2.6% of revenue, in the comparable period last year. The year-over-year increase of $10.7 million was primarily due to higher gross profit and lower selling, general and administrative expenses. Non-GAAP adjusted operating income for the first quarter of 2026 was $18.0 million, or 8.6% of revenue, compared to $7.6 million, or 4.0% of revenue, in the comparable period last year.

Adjusted EBITDA for the first quarter of 2026 was $35.4 million, or 16.9% of revenue, compared to $29.7 million, or 15.4% of revenue, for the comparable period in 2025.

Interest expense for the first quarter of 2026 was $4.0 million compared to $3.3 million in the comparable period of 2025. The year-over-year increase was primarily due to a higher debt balance, partially offset by lower interest rates.

During the first quarter of 2026, the net cash provided by operations was $11.2 million compared to $0.8 million during the first quarter of 2025. The higher net cash provided by operations during the first quarter of 2026 was primarily due to higher net income and higher contract liabilities, partially offset by lower accrued and other liabilities.

\* As restated in the Company's Form 10-K/A filed with the Securities and Exchange Commission on May 8, 2026.

**Business Segment Information**

<u>Electronic Systems</u>

Electronic Systems segment net revenue for the quarter ended April 4, 2026 was $117.6 million, compared to $109.1 million for the first quarter of 2025. The year-over-year increase was primarily due to the following in the Company's key end-use markets:

&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 fixed-wing aircraft and missile platforms, partially offset by lower rates on electronic warfare and radar platforms; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $4.6 million higher revenue in the Company's commercial aerospace end-use markets due to higher rates on other commercial aerospace and large aircraft platforms.

In addition, revenue for the Company's industrial end-use markets for the first quarter of 2026 decreased $1.4 million compared to the first quarter of 2025 mainly due timing of orders.

------

<u>Structural Systems</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $0.1 million higher revenue within the Company's military and space end-use markets due to higher rates on selected missile platforms, partially offset by lower rates on selected rotary-wing aircraft platforms.
